ARTICLE 2

CREDIT FACILITIES

2.01 Revolving Credit

(1) Establishment

Subject to the terms and conditions of this Agreement, each Lender severally (and not jointly or jointly and severally) agrees to make Advances rateably to the Borrower in accordance with its Commitment pursuant to a revolving line of credit (the “Revolving Credit”) from time to time on any Business Day during the Revolving Period by way of Cdn. Prime Rate Loans, US Base Rate Loans, LIBOR Loans, Bankers’ Acceptances and Letters of Credit.

(2) Use of Proceeds

Advances shall only be used by the Borrower for general corporate purposes (which for greater certainty shall include financing capital expenditures and Permitted Acquisitions).

2.02 Revolving Credit Limit

(1) The Outstanding Principal Amount of the Revolving Credit shall not at any time exceed the Revolving Credit Limit and the aggregate Outstanding Principal Amount of Letters of Credit shall not at any time exceed $75,000,000.

(2) the Borrower may, from time to time, upon not less than 30 days prior written notice (a “Cancellation Notice”) to the Administrative Agent, permanently reduce the Revolving Credit Limit (and at the same time permanently reduce the Commitments of the Lenders in respect thereof, pro rata) by the amount of the Unutilized Portion of the Revolving Credit or any part thereof in excess of Cdn. $5,000,000.

2.03 Overdrafts

(1) The Borrower shall be entitled to incur overdrafts (“Overdrafts”) to a Cdn. Dollar account and a US Dollar account (collectively, the “Overdraft Accounts”) of the Borrower with, and designated for such purpose by, the Overdraft Lender in an

- 31 -

aggregate Outstanding Principal Amount which when added to the aggregate Outstanding Principal Amount of all other outstanding Advances made by the Overdraft Lender to the Borrower shall not exceed the Commitment of the Overdraft Lender. Overdrafts shall only be used for general corporate purposes of the Borrower. Overdrafts in Cdn. Dollars shall be deemed to be Cdn. Prime Rate Loans, and Overdrafts in US Dollars shall be deemed to be US Base Rate Loans, made by the Overdraft Lender to the Borrower under the Revolving Credit. Notwithstanding any other provisions hereof no notice of any kind is required of the Borrower to obtain or repay any Cdn. Prime Rate Loan or US Base Rate Loan in the form of an Overdraft and no such Loan may be converted to any other type of Advance. Except as otherwise expressly provided in this section, Overdrafts shall be made solely by the Overdraft Lender without assignment to, or participation by, any of the other Lenders. Interest on Overdrafts and any fees relating to the administration and operation of the Overdraft Accounts shall be for the sole benefit of, and debited to the Overdraft Accounts by, the Overdraft Lender. Subject to the other terms and conditions hereof, Overdrafts shall be paid as and when deposits are made to the Overdraft Accounts.

(2) In the event that a New Advance (other than by way of an Overdraft) would result in the Outstanding Principal Amount of all Advances (including Overdrafts) owing to the Overdraft Lender under the Revolving Credit exceeding the Commitment of the Overdraft Lender, the Borrower shall, on or prior to the Borrowing Date of the New Advance, reduce the Overdrafts by the amount required to reduce the Outstanding Principal Amount of all Advances (including the Overdraft Lender’s rateable portion of the New Advance) owing to the Overdraft Lender to the amount of its Commitment. In the event that the Outstanding Principal Amount of the Overdrafts (the “Overdraft Exposure”) exceeds $5,000,000 at the beginning of the second Business Day (or such other day as may be agreed by the Overdraft Lender and the Borrower) of any calendar week, the Overdraft Lender may, and shall at any time that a Default or Event of Default has occurred and is continuing, give written notice (an “Overdraft Repayment Notice”) of the amount of the Overdraft Exposure to the Administrative Agent and require the Overdrafts to be paid in full. Upon receipt of an Overdraft Repayment Notice the Administrative Agent shall promptly give written notice (a “Funding Notice”) to all of the Lenders (including the Overdraft Lender) that the Borrower is required to pay the Overdrafts in full from Loans made rateably by all of the Lenders under the Revolving Credit and setting out the amount of the Cdn. Prime Rate Loan and US Base Rate Loan (each, a “Required Overdraft Repayment Loan”) that each Lender is required to make to the Borrower rateably in accordance with its Commitment under the Revolving Credit in order for the Overdrafts to be paid in full. Upon receipt of a Funding Notice each Lender shall pay its Required Overdraft Repayment Loans to the Administrative Agent, and the Borrower shall be deemed to have been advanced such Required Overdraft Repayment Loans by the Lender under the Revolving Credit. The Administrative Agent shall immediately deposit, upon receipt, such Required Overdraft Loans to the Overdraft Accounts in payment of the Overdrafts and the Borrower shall be deemed to have irrevocably directed and authorized the Administrative Agent to make such deposits.

- 32 -

(3) In the event that a Lender does not transfer the funds representing its Required Overdraft Repayment Loans to the Administrative Agent for the benefit of the Overdraft Lender when required, such Defaulting Lender shall pay the Administrative Agent on demand, the amount (the “Funding Shortfall”) that the Defaulting Lender has failed to transfer to the Administrative Agent. Until such time as the Funding Shortfall has been paid to the Administrative Agent for the benefit of the Overdraft Lender, the Overdraft Lender shall be entitled to all interest payable by the Borrower to the Defaulting Lender in respect of the Required Overdraft Repayment Loan represented by the Funding Shortfall and for purposes of Section 12.04 only, the Commitment of the Defaulting Lender shall be treated as a Commitment of the Overdraft Lender (with the result that the Defaulting Lender shall not be entitled to receive any payments on account of the Obligations and all payments that would have otherwise been received by the Defaulting Lender shall be payable to the Overdraft Lender on account of the Funding Shortfall until paid in full). If any amount transferred by a Lender to the Administrative Agent or paid to the Overdraft Lender under this section and deemed to be advanced to the Borrower must be repaid by the Administrative Agent, the Overdraft Lender or other Lender to the Borrower, the Overdrafts shall not be reduced by the amount that is required to be repaid and the relevant Lenders shall purchase participations in the Overdrafts (without recourse to the Overdraft Lender) for an amount which will, or otherwise effect transactions to, achieve the financial results contemplated by this section.

(4) For greater certainty, the Lenders shall be obligated to transfer the funds representing the Required Overdraft Repayment Loans to the Administrative Agent for the benefit of the Overdraft Lender in payment of the Overdrafts in full irrespective of whether (i) any Default or Event of Default has occurred and is continuing; (ii) any conditions precedent under ARTICLE 6 have been satisfied; (iii) the Borrower has requested the Required Overdraft Repayment Loans; (iv) the Revolving Credit has been terminated; (v) the Revolving Period has expired; or (vi) the occurrence of any other event or circumstance.

2.04 Mandatory Prepayments and Credit Reductions

(1) Subject to the rights of the Administrative Agent and the Majority Lenders to accelerate payment pursuant to Section 10.02, the Borrower shall pay, and there shall become due and payable by the Borrower to the Administrative Agent for the benefit of the Lenders, on the Maturity Date (i) the Outstanding Principal Amount of all Loans made to the Borrower, plus any accrued and unpaid interest thereon and any amounts payable pursuant to Section 13.06(3) in respect thereof; (ii) the Outstanding Principal Amount of all BAs issued by or on behalf of the Borrower; (iii) the Outstanding Principal Amount of all Letters of Credit issued for the account of the Borrower; (iv) all other outstanding Obligations that are due and payable by the Borrower; and (v) an amount (the “Sanger Cash Collateral”) equal to the Maximum Sanger LC Amount. Any amount paid by the Borrower pursuant to this section shall be allocated in respect

- 33 -

of the Obligations (the “Cash Collateralized Obligations”) relating to BAs, undrawn amounts under Letters of Credit and the Sanger Cash Collateral after the payment of all other Obligations (other than Obligations under Secured Hedging Agreements that are not then due and payable) has been made in full. All amounts (the “Cash Collateral”) paid in respect of the Cash Collateralized Obligations shall be held as security by the Administrative Agent for the Obligations pursuant to the one or more Security Documents constituting a perfected Lien therein in favour of the Administrative Agent and shall be applied in payment of the Cash Collateralized Obligations and any other Obligations of the Borrower as and when due. The Borrower shall execute and deliver all such agreements and documents and do all such further things as may be reasonably required to give effect to the foregoing security arrangements. In the event that there is any Cash Collateral remaining after all of the Obligations (other than Obligations under Secured Hedging Agreements that are not then due and payable) have been paid in full, it shall, except as may otherwise be required by Applicable Law, be paid over to the Borrower.

(2) The Borrower shall cause the first $70,000,000 of the Net Proceeds from any Refinancing Debt Issues (and the Borrower shall give the Administrative Agent reasonable prior written notice of each such Refinancing Debt Issue) to be used upon the completion of each such Refinancing Debt Issue to pay all outstanding St. Leon Senior Debt (whether due or not). Upon the St. Leon Debt being repaid in full by the Net Proceeds from any Refinancing Debt Issues, the Borrower shall cause the St. Leon Credit Agreement and all commitments of the lenders thereunder to be immediately terminated and shall thereafter use any remaining or new Net Proceeds from any Refinancing Debt Issue to prepay outstanding Obligations to the extent required to reduce the Outstanding Principal Amount of the Revolving Credit to the amount equal to the Maximum Credit Limit minus $22,000,000 (the occurrence of all of the foregoing being, the “Completion of the St. Leon Refinancing”). Upon the Completion of the St. Leon Refinancing the Maximum Credit Limit shall be reduced by $22,000,000 (and the Commitments of the Lenders shall be permanently reduced, pro rata, by the same amount).

(3) The Borrower shall cause the Net Proceeds from a Capital Transaction to be used for Approved Reinvestments or to prepay outstanding Advances within the 12 month period (the “Reinvestment Period”) following the completion of the Capital Transaction. Any non-cash consideration received as part of a Capital Transaction will be treated as being an Investment made with the Net Proceeds thereof if it is not applied to prepay Advances or used for an Approved Reinvestment within the Reinvestment Period. In the event that the Net Proceeds from a Capital Transaction are equal to or greater than $35,000,000, the Maximum Credit Limit shall be reduced, and the Commitments of the Lenders shall be permanently reduced pro rata, automatically on the completion of the Capital Transaction by the amount of the Net Proceeds.

- 34 -

(4) In the event that the aggregate Outstanding Principal Amount under the Revolving Credit shall on any day exceed the Revolving Credit Limit as a result of any reduction made to the Maximum Credit Limit or any change in the exchange rate used to calculate the Outstanding Principal Amount of Advances outstanding in US Dollars, the Borrower shall, on the 3rd Business Day following its receipt of written notice thereof from the Administrative Agent, prepay (a “Mandatory Prepayment”) outstanding Advances to the extent required to reduce the Outstanding Principal Amount of the Revolving Credit to the Revolving Credit Limit.

(5) In the event that any Mandatory Prepayment would require any LIBOR Loan to be repaid prior to the end of the applicable LIBOR Period, any Banker’s Acceptance being repaid prior to the end of its term or any Letter of Credit being repaid (by returning it to the Issuing Lender for cancellation) prior to its expiry date, the Borrower may, in lieu of prepaying or causing the prepayment of such outstanding Advances (also “Cash Collateralized Obligations”), deposit cash (also “Cash Collateral”) with the Administrative Agent in an amount equal to the amount by which such outstanding Advances would need to be prepaid in order to reduce the Outstanding Principal Amount of the Revolving Credit to the Revolving Credit Limit, as security for the Obligations pursuant to one or more Security Documents constituting perfected Liens therein in favour of the Administrative Agent, having the priority set out in Section 7.07, provided the Security Documents and such opinions and other acts and things as may be required by the Administrative Agent in connection therewith are, in all respects, reasonably satisfactory, and are completed and delivered, to the Administrative Agent at the time that the prepayment would have otherwise been due. Such Cash Collateral shall be applied by the Administrative Agent in payment of such Cash Collateralized Obligations as and when due. The Borrower shall execute and deliver all such further agreements and documents and do all such further things as may be reasonably required to give effect to the foregoing security arrangements. In the event the Administrative Agent holds any such Cash Collateral for any Letter of Credit and such Letter of Credit is repaid (by return to the Issuing Lender for cancellation) at a time when the Outstanding Principal Amount of the Revolving Credit does not exceed the Revolving Credit Limit, any such Cash Collateral shall promptly be paid to the Borrower.

2.05 Conversions and Continuations of Advances

Subject to the terms and conditions of this Agreement, the Borrower may convert a Loan from one type to another or into Bankers’ Acceptances, continue LIBOR Loans for additional LIBOR Periods and roll over Bankers’ Acceptances into new Acceptances or convert Acceptances into Loans. No Conversion or Continuation shall constitute a repayment or prepayment of any Advance.

- 35 -

2.06 Standby Fee

During the Revolving Period the Borrower shall pay the Administrative Agent, for the rateable benefit of the Lenders, a standby fee (the “Standby Fee”) at the Applicable Rate on the daily Available Commitment under the Revolving Credit, payable in Cdn. Dollars quarterly in arrears on the 1st Business Day of January, April, July and October of each year for the period up to and including the last day of the preceding calendar quarter and on the date that the aggregate Outstanding Principal Amount of the Revolving Credit becomes due and payable.

2.07 Rateable Advances and Payments

(1) Unless the Administrative Agent receives notice from a Lender prior to the date of an Advance that the Lender will not make its rateable portion of the Advance available to the Administrative Agent, the Administrative Agent may assume that the Lender has made its portion available to the Administrative Agent on the date of the Advance and the Administrative Agent may, in reliance upon such assumption, make a corresponding amount available to the Borrower on such date. If and to the extent the Lender has not made its rateable portion available to the Administrative Agent, the Lender shall pay the corresponding amount to the Administrative Agent immediately upon demand. If the Lender pays the corresponding amount to the Administrative Agent, the amount so paid shall constitute the Lender’s part of the Advance for purposes of this Agreement. If the Lender does not pay the amount to the Administrative Agent upon demand and such amount has been made available to the Borrower, the Borrower shall pay the corresponding amount to the Administrative Agent upon demand and agrees that any such amount received and so reimbursed would not and shall not constitute an Advance. The Administrative Agent shall be entitled to recover interest on the corresponding amount from the Borrower from the date the amount was made available to the Borrower until the date it is repaid to the Administrative Agent at the rate applicable to Cdn. Prime Rate Loans, in the case of amounts made available in Cdn. Dollars, or the rate applicable to US Base Rate Loans, in the case of amounts made available in US Dollars. A Lender who defaults in the payment of any corresponding amount to the Administrative Agent under this section shall pay (as compensation to the Administrative Agent for the additional services required of the Administrative Agent as a result of the Lender’s default) interest to the Administrative Agent at the Interbank Rate on the corresponding amount from the date that the amount was made available to the Borrower by the Administrative Agent until the date it is repaid to the Administrative Agent. Nothing in this section shall affect any Commitment of any Lender to the Borrower.

(2) Unless the Administrative Agent receives notice from the Borrower prior to the date on which any payment is due to the Lenders that the Borrower will not make the payment in full, the Administrative Agent may assume that the Borrower has made the payment in full on that date and the Administrative Agent may, in reliance upon that

- 36 -

assumption, distribute to each Lender on the due date an amount equal to the amount then due to the Lender. If and to the extent the Borrower has not made such a payment in full, each Lender shall repay to the Administrative Agent upon demand the amount distributed to it together with interest at the Interbank Rate from the date such amount was distributed to the Lender until the date the Lender repays it to the Administrative Agent.

(3) References in this Agreement to a Lender’s rateable portion of Advances, rateable share of payments of principal, interest, fees or any other amount, shall mean and refer to a rateable portion or share as nearly as may be rateable in the circumstances, as determined in good faith by the Administrative Agent. Each such determination by the Administrative Agent shall be prima facie evidence of such rateable share.

(4) The Administrative Agent shall give each Lender prompt notice of (i) each Borrowing Notice received from the Borrower and of each Lender’s rateable portion of any Advance, and (ii) any other written notice received by it under this Agreement.

2.08 Payments under this Agreement

(1) All payments to be made by the Borrower to any Finance Party under this Agreement shall, unless otherwise required by the Administrative Agent, be made by the Administrative Agent debiting the amount of the payment in the relevant currency to the appropriate Operating Account on the date upon which the payment is due in accordance with the terms hereof. The Borrower shall ensure that there are sufficient funds having same day value to the Lenders on deposit in the appropriate Operating Accounts or that the credit available under the Overdraft Accounts is sufficient to cover all such payments on the date of payment. Any amount payable by the Borrower hereunder which is not paid to the Administrative Agent or any Lender when due may be debited by the Administrative Agent or any Lender to any other accounts of the Borrower. The Administrative Agent shall distribute all amounts due and payable to each Lender promptly upon receipt of payment. Any payment received by the Administrative Agent after 1:00 p.m. shall be deemed, for all purposes hereof, to have been received by the Administrative Agent on the next Business Day. Any amount received by the Administrative Agent for the account of the Lenders shall be held in trust for their benefit pending distribution and shall bear interest at the Interbank Rate from and after the date of receipt by the Administrative Agent.

(2) Unless otherwise expressly provided herein, the Administrative Agent shall make Advances and other payments to the Borrower by crediting, or causing to be credited, the relevant Operating Account with the amount of the payment.

(3) The Borrower shall give the Administrative Agent a Payment Notice in respect of any payment to be applied in reduction of the Outstanding Principal Amount of any Advances, other than Overdrafts.

- 37 -

(4) No Lender shall be responsible for any default by any other Lender to make Advances to the Borrower nor shall the Commitment of any Lender be increased as a result of any such default.

2.09 Application of Payments

All amounts received by the Administrative Agent from or on behalf of the Borrower and not previously applied pursuant to this Agreement shall, notwithstanding any Payment Notice, be applied or paid by the Administrative Agent (i) firstly, in reduction of any amount due and owing to the Administrative Agent for services rendered under this Agreement; (ii) secondly, in reduction of the obligation of the Borrower to pay any unpaid interest and any fees which are due and owing hereunder; (iii) thirdly, in reduction of the obligation of the Borrower to pay any Claims or Losses referred to in Sections 13.06, 13.07 or 13.08; (iv) fourthly, in reduction of the obligation of the Borrower to pay any amounts due and owing on account of the Outstanding Principal Amount of the Loans; (v) fifthly, in reduction of the obligation of the Borrower to pay any other unpaid Advances which are due and owing; (vi) sixthly, in reduction of any other obligation of the Borrower under this Agreement; (vii) seventhly, in reduction of any Obligations due and owing in respect of any Hedging Agreements, pro rata, in accordance with the outstanding amount owed to each Lender in respect thereof; and (viii) lastly, to the Borrower or such other Persons as may be entitled to receive the remainder.

2.10 Netting

In the event that on any date amounts that would otherwise be payable pursuant to this Agreement by each of the Administrative Agent and a Lender to the other, or by the Borrower and a Lender to the other, then, on such date, each party’s obligation to make payment of any such amount will be automatically satisfied and discharged and, if the aggregate amount that would otherwise have been payable by one party exceeds the aggregate amount that would otherwise have been payable by the other party, replaced by an obligation upon the party by whom the larger aggregate amount would have been payable to pay to the other party the excess of the larger aggregate amount over the smaller aggregate amount.

2.11 Computation of Interest and Fees

All computations of interest hereunder shall be made by the Administrative Agent taking into account the actual number of days in the period for which interest is payable, and in the case of Cdn. Prime Rate Loans and US Base Rate Loans, on the basis of a year of 365 days, and in the case of LIBOR Loans or any calculation of the Federal Funds Rate, on the basis of a year of 360 days. All computations of fees shall be made by the Administrative Agent on the basis of a year of 365 days, taking into account the actual number of days in the period for which the fees are payable. For purposes of the Interest Act (Canada) whenever any interest or fee under

- 38 -

this Agreement is calculated at any time using a rate based on a year of 360 days, or is calculated during a leap year using a rate based on a year of 365 days, the rate determined pursuant to such calculation, when expressed as an annual rate is equivalent to the applicable rate based on a year of 360 days or 365 days, as the case may be, multiplied by the actual number of days in the calendar year in which the period for which the interest or fee is payable ends, divided by 360 or 365 days, as the case may be. The principle of deemed reinvestment does not apply to any interest calculation under this Agreement and the rates of interest and fees stipulated in this Agreement are intended to be nominal rates and are not effective rates or yields.

2.12 Agency Fees

The Borrower shall pay the Administrative Agent, for its own account, an agency fee in an amount to be agreed upon in writing by the Administrative Agent and the Borrower.

- 39 -

3.02 Conversion and Continuation Rights

Prime Rate Loan or US Base Rate Loan, the date on which the Loan is repaid in full or converted to another type of Loan or into Bankers’ Acceptances.

- 40 -

prepayment all of the other outstanding Advances under the Revolving Credit are being paid in full, in which case, all accrued and unpaid interest shall be paid at the time of the prepayment.

(1) A Borrowing Notice in respect of Bankers’ Acceptances shall be signed by the Borrower and given to the Administrative Agent not later than 11:00 a.m. 3 Business Days prior to the requested Borrowing Date. The Administrative Agent shall, promptly following receipt of a Borrowing Notice in respect of Bankers’ Acceptances, advise each BA Lender and each Non-BA Lender of the face amount and term of each Draft to be completed and purchased by it. The term of all Bankers’ Acceptances issued pursuant to a Borrowing Notice shall be identical. The face amount of each Bankers’ Acceptance shall be Cdn. $100,000 or any whole multiple of Cdn. $100,000 and the aggregate face amount of Bankers’ Acceptances issued pursuant to any Borrowing Notice shall not be less than Cdn. $5,000,000 in the aggregate. Subject to the following, each Bankers’ Acceptance shall be dated the Borrowing Date on which it is issued and shall be for a term of one, two, three or six months. The Borrower shall not be entitled to select any term for a Bankers’ Acceptance that expires after the Maturity Date or conflicts with, in the opinion of the Administrative Agent, any payment obligations of the Borrower under ARTICLE 2. The aggregate face amount (the “Individual Lender Face Amount”) of the Drafts to be completed and purchased by each BA Lender and Non-BA Lender shall be equal to the pro rata share of such Lender of the aggregate face amount (the “Requested Face Amount”) of the Bankers’ Acceptances requested by the Borrower, except that, if an Individual Lender Face Amount would not be a whole multiple of Cdn. $100,000, such Individual Lender Face Amount shall be increased or reduced by the Administrative Agent in its sole discretion to the nearest whole multiple of Cdn. $100,000. In order to facilitate the issuance of Bankers’ Acceptances pursuant to this Article, the Borrower hereby irrevocably authorizes each Lender and appoints each Lender its attorney to complete, sign and endorse Drafts on its behalf in handwritten form or by facsimile or mechanical signature or otherwise and, once so completed, signed and endorsed to accept, purchase, discount or negotiate such Bankers’ Acceptances in accordance with this Article. Drafts so completed, signed, endorsed and negotiated on behalf of the Borrower by any Lender shall bind the Borrower as fully and effectively as if so performed by an authorized officer of the Borrower and shall mature on the last day of the period specified therein. Any Bankers’ Acceptance purchased by a Lender may be held by the Lender for its own account or sold or traded in the money market, either directly or through securities brokers or

- 43 -

dealers or a clearing house within the meaning of the Depository Bills and Notes Act (Canada) in accordance with arrangements made by the Lender.

(2) The Borrower shall pay each Bankers’ Acceptance issued on its behalf on its maturity by paying the Outstanding Principal Amount thereof to the Administrative Agent. The Borrower shall not claim any days of grace for the payment at maturity of any Bankers’ Acceptance and the obligations of the Borrower in respect thereof shall be unconditional and irrevocable and shall be paid strictly in accordance with the terms of this Agreement under all circumstances, including, without limitation, irrespective of any lack of validity or enforceability of any Draft accepted as a Bankers’ Acceptance, or the existence of any claim, setoff, defence or other right which the Borrower may have at any time against the holder of a Bankers’ Acceptance, or any other Person, whether in connection with this Agreement or otherwise.

(3) Each Lender on the applicable Borrowing Date, shall (i) complete and accept one or more Drafts as advised by the Administrative Agent pursuant to this Article; (ii) purchase the resulting Bankers’ Acceptances at a price equal to the BA Discount Proceeds applying thereto; and (iii) after deducting the Stamping Fee payable to the Lender in respect of such Acceptances, pay the remaining balance of the purchase price to the Administrative Agent.

4.02 Stamping Fee

Upon the issuance of a Bankers’ Acceptance by a Lender, the Borrower, shall pay the Lender a fee (the “Stamping Fee”) equal to (i) the Applicable Margin in effect on the Borrowing Date on which the Bankers’ Acceptance is issued; multiplied by (ii) the face amount of the Bankers’ Acceptance; multiplied by (iii) a fraction, (A) the numerator of which is the term to maturity of the Bankers’ Acceptance, and (B) the denominator of which is 365 days. The Stamping Fee paid by the Borrower in respect of a Bankers’ Acceptance shall be recalculated from time to time if there is any change in the Applicable Margin during the term of the Bankers’ Acceptance. All adjustments in respect of Stamping Fees shall be payable by the Borrower to the Administrative Agent for the rateable benefit of the Lenders or by the Lenders, rateably, to the Borrower, as the case may be, on or prior the 10^th Business Day following the date on which the Administrative Agent gives notice of the adjustments to the Borrower and the Lenders.

4.03 Conversion and Continuation Rights

(1) The Borrower may, pursuant to a Borrowing Notice given to the Administrative Agent not later than 11:00 a.m. 3 Business Days prior to the maturity of a Bankers’ Acceptance, elect to (i) issue a replacement Bankers’ Acceptance on the maturity of the outstanding Acceptance; (ii) convert any part of the Outstanding Principal Amount of the Bankers’ Acceptance into one or more Loans on the maturity date of the outstanding Acceptance; or (iii) pay the Bankers’ Acceptance on its maturity date as provided herein.

- 44 -

(2) Each Borrowing Notice given in respect of the Conversion or Continuation of a Bankers’ Acceptance shall specify (i) the requested date of the Conversion or Continuation (which shall be the maturity date of the Bankers’ Acceptance); and (ii) the type of Loan into which the outstanding Acceptance is to be converted or the Principal Amount and term of any replacement Bankers’ Acceptances.

(3) In the event that the Borrower shall fail to make an election in respect of any Bankers’ Acceptance pursuant to this section, the Bankers’ Acceptance shall automatically be converted upon maturity into a Cdn. Prime Rate Loan.

4.04 Bankers’ Acceptances Unavailable

In the event that the Administrative Agent determines in good faith, and so notifies the Borrower, that by reason of circumstances affecting the money market, there is no market for Bankers’ Acceptances, (i) the right of the Borrower to borrow by way of Bankers’ Acceptances shall be suspended until the Administrative Agent determines in good faith that the circumstances causing the suspension no longer exist and so notifies the Borrower; and (ii) if Bankers’ Acceptances have been requested but not accepted and purchased pursuant to a Borrowing Notice, the request for the Bankers’ Acceptances shall be deemed to be a request for Cdn. Prime Rate Loans in an amount equal to the Principal Amount of the requested Bankers’ Acceptances.

ARTICLE 5

LETTERS OF CREDIT

5.01 Letters of Credit

Advances under the Revolving Credit by way of Letters of Credit shall be made available by the Issuing Lender on behalf of all Lenders pursuant to a Borrowing Notice signed by the Borrower and given to the Administrative Agent well enough in advance of the requested Borrowing Date to provide the Issuing Lender a reasonable period of time to review any related documents or information and prepare the requested Letter of Credit (at a minimum, the Borrowing Notice must be given to the Administrative Agent not later than 11:00 a.m. 3 Business Days prior to the requested Borrowing Date). Concurrently with the delivery of a Borrowing Notice requesting a Letter of Credit, the Borrower shall execute and deliver to the Administrative Agent the LC Documents required by the Issuing Lender in respect of the requested type of Letter of Credit. No Letter of Credit shall have a term of more than 12 months (but may contain a clause which will automatically renew the Letter of Credit for successive 12 month (or shorter) terms from time to time unless prior to the date of such renewal, the Issuing Lender notifies the beneficiary that the Letter of Credit will not be renewed) and shall otherwise be, in form and substance, satisfactory to the Issuing Lender. Unless, otherwise agreed by the Issuing Lender, no Letter of Credit shall have a term that extends past the Maturity Date.

- 45 -

5.02 Fees

The Borrower shall pay the Administrative Agent for the rateable benefit of the Lenders a fee (an “LC Issuance Fee”) for the issuance and renewal of each Letter of Credit issued for its account under the Revolving Credit and an LC Fronting Fee to the Issuing Lender for its own account. The LC Issuance Fee and LC Fronting Fee shall be payable in advance on the issue date of the Letter of Credit and on each renewal date thereof in the currency in which the Letter of Credit has been issued. In addition to the LC Fronting Fee payable in respect of a Letter of Credit, the Borrower shall also pay the Issuing Lender, for its own account, its customary cable charges and other standard administrative charges in respect of any amendment, transfer or renewal of the Letter of Credit or any drawings thereunder. The LC Issuance Fee for a Letter of Credit shall equal the greater of (i) $150 (in the currency of the Letter of Credit); and (ii) the amount equal to (A) the maximum liability of the Issuing Lender on the date that the fee is payable; multiplied by (B) a fraction (1) the numerator of which shall equal the product resulting from multiplying the Applicable Rate on the date that the fee is due and payable by the number of days in the term of the Letter of Credit; and (2) the denominator of which shall consist of 365 days. The LC Issuance Fees paid by the Borrower in respect of each Letter of Credit shall be recalculated from time to time if there is any change in the Applicable Rate during the term of the Letter of the Credit. All adjustments in respect of the LC Issuance Fees paid in respect of a Letter of Credit shall be payable by the Borrower to the Administrative Agent for the rateable benefit of the Lenders or by the Lenders, rateably, to the Borrower, as the case may be, on or prior the 10^th Business Day following the date on which the Administrative Agent gives notice of the adjustments to the Issuing Lender and the Borrower.

5.03 Participation

Each Lender, upon issuance of a Letter of Credit under the Revolving Credit (or upon the execution and delivery of this Agreement in the case of each Existing Letter of Credit) shall be deemed to have purchased, without recourse, a risk participation from the Issuing Lender in the Letter of Credit and the obligations arising thereunder, in each case in an amount equal to its pro rata share of the obligations under the Letter of Credit (based on the respective Commitments of the Lenders) and shall absolutely, unconditionally and irrevocably assume, as primary obligor and not as surety, and be obligated to pay to the Issuing Lender therefor and discharge when due, its pro rata share of the obligations arising under the Letter of Credit. Without limiting the scope and nature of each Lender’s participation in any Letter of Credit, to the extent that the Issuing Lender has not been reimbursed as required hereunder or under any Letter of Credit issued under the Revolving Credit, each Lender shall pay to the Issuing Lender its pro rata share of such unreimbursed amounts pursuant to the provisions hereof. Simultaneously with the making of each such payment by a Lender to the Issuing Lender, the Lender shall, automatically and without any further action on the part of the Issuing Lender or the Lender, acquire a participation in an amount equal to such payment

- 46 -

(excluding the portion of such payment constituting interest owing to the Issuing Lender) in the related unreimbursed amount and in the interest thereon and in the related LC Documents. The obligation of a Lender to reimburse the Issuing Lender shall be absolute and unconditional and shall not be affected by the occurrence of a Default, an Event of Default or any other occurrence or event. Any such reimbursement shall not relieve or otherwise impair the obligation of the Borrower to reimburse the Issuing Lender under any Letter of Credit, together with interest as provided herein.

5.04 Reimbursement Obligations

(1) In the event of any drawing under a Letter of Credit outstanding under the Revolving Credit, the Administrative Agent shall promptly notify the Borrower and the Lenders thereof, and the Borrower shall reimburse the amount drawn to the Issuing Lender in the currency of the drawing in same day funds not later than 12:00 noon, on the date of such drawing, if the Borrower shall have received notice thereof prior to 10:00 a.m. on such date, or, if such notice has not been received by the Borrower prior to such time on such date, then not later than 12:00 noon, on (i) the Business Day that the Borrower receives such notice, if such notice is received prior to 10:00 a.m., on the day of receipt, or (ii) the Business Day immediately following the day that the Borrower receives such notice, if such notice is not received prior to such time on the day of receipt. In the event that the Borrower fails to reimburse the Issuing Lender following a drawing as contemplated by the immediately preceding sentence, the Borrower shall be deemed to have requested a Loan from the Lenders under the Revolving Credit (a Cdn. Prime Rate Loan in the case of a drawing in Cdn. Dollars, and a US Base Rate Loan, in the case of a drawing in US Dollars) on the date such reimbursement was required, in an amount and in the currency of the drawing, the proceeds of which will be used to satisfy the reimbursement obligations of the Borrower to the Issuing Lender in respect of the drawing.

(2) Each Lender hereby irrevocably agrees to make its pro rata share of each Loan deemed to have been requested pursuant to subsection (1) above immediately upon any such deemed request in the amount, in the currency, in the manner and on the date specified in (1) above notwithstanding (i) the amount of the Loan may not comply with the requirements hereunder or may result in the Outstanding Principal Amount of the Revolving Credit exceeding the Revolving Credit Limit, (ii) whether any conditions specified herein are then satisfied, (iii) whether a Default or an Event of Default then exists, (iv) that any such request or deemed request for a Loan is not made by the time otherwise required hereunder, (v) whether the date of such Borrowing is a date on which Loans are otherwise permitted to be made hereunder or (vi) any termination of the Commitments relating thereto at any time prior to or contemporaneously with such Borrowing. In the event that any such Loan cannot for any reason be made on the date otherwise required above (including, as a result of the commencement of any insolvency proceeding under any Applicable Laws with respect to any APCO Entities), then each Lender shall promptly purchase (as of the date such Borrowing would otherwise have

- 47 -

occurred, but adjusted for any payments received from the Borrower on or after such date and prior to such purchase) from the Issuing Lender such participation in the outstanding LC Obligations as shall be necessary to cause each such Lender to share in such LC Obligations rateably (based upon the respective Commitments of the Lenders (determined before giving effect to any termination of the Commitments pursuant to Section 10.02)), provided that at the time any purchase of a participation pursuant to this sentence is actually made, the purchasing Lender shall be required to pay to the Issuing Lender, to the extent not paid to the Issuing Lender by the Borrower, interest on the principal amount of the participation purchased for each day from and including the day upon which such Borrowing would otherwise have occurred to but excluding the date of payment for such participation, at a rate equal to the Interbank Rate.

(3) The reimbursement obligations of the Borrower hereunder shall be absolute and unconditional under all circumstances irrespective of any rights of setoff, counterclaim or defence to payment the Borrower may claim or have against the Issuing Lender, any other Finance Parties, the beneficiary of the Letter of Credit drawn upon or any other Persons, including any defence based on any failure of the Borrower to receive consideration or the legality, validity, regularity or unenforceability of the Letter of Credit.

(4) A Letter of Credit issued under the Revolving Credit may contain a statement that the Letter of Credit is for the account of the Borrower and another Person, however, notwithstanding such statement, the Borrower shall be the actual and sole account party for all purposes of this Agreement for such Letter of Credit and no such statement shall affect any Obligations of the Borrower to the Lenders in respect thereof.

5.05 Dealing with Letters of Credit

(1) The Borrower agrees that neither the Issuing Lender nor its officers, directors or correspondents shall assume liability for, or be responsible for, (i) the use which may be made of any Letter of Credit; (ii) any acts or omissions of the beneficiary of any Letter of Credit including the application of any payment made to such beneficiary; (iii) the form, validity, sufficiency, correctness, genuineness or legal effect of any document or instrument relating to any Letter of Credit, even if such document or instrument should in fact prove to be in any respect invalid, insufficient, inaccurate, fraudulent or forged; (iv) payment by the Issuing Lender of any draft which does not comply with the terms of any Letter of Credit, unless such payment results from the gross negligence or wilful misconduct of the Issuing Lender; (v) any failure to note the amount of any draft on any Letter of Credit or on any related document or instrument; (vi) any failure of the beneficiary of any Letter of Credit to meet the obligations of such beneficiary to the Borrower or any other Person; (vii) any errors, inaccuracies, omissions, interruptions or delays in transmission or delivery of any messages, directions or correspondence by mail, facsimile or otherwise, whether or not they are in cipher; (viii) any inaccuracies in the translation of any messages, directions or

- 48 -

correspondence or for errors in the interpretation of any technical terms; (ix) or any failure by the Issuing Lender to make payment under any Letter of Credit as a result of any Applicable Laws, control or restriction rightfully or wrongfully exercised or imposed by any Governmental Authority or as a result of any other cause beyond the control of the Issuing Lender or its officers, directors or correspondents.

(2) The obligations of the Borrower under this ARTICLE 5 with respect to each Letter of Credit shall be absolute, unconditional and irrevocable, and shall be performed strictly in accordance with the terms of this Agreement under all circumstances including (i) any matter referred to in Section 5.05(1); (ii) any invalidity of any obligation secured by any Letter of Credit; (iii) any incapacity, disability or lack or limitation of status or of power of the Borrower or the beneficiary of any Letter of Credit; (iv) any lack of validity or enforceability of any Letter of Credit; (v) the existence of any claim, set-off, defence or other right which the Borrower may have at any time against the Issuing Lender, any other Finance Party, the beneficiary of any Letter of Credit or any other Person; or (vi) any breach of contract or other dispute between the Borrower and the Issuing Lender any other Finance Party, the beneficiary of any Letter of Credit or any other Person.

(3) The Issuing Lender may accept as complying with the terms of any Letter of Credit any document or instrument required by such Letter of Credit to be completed, signed, presented or delivered by or on behalf of any beneficiary thereunder which has been completed, signed, presented or delivered by a receiver, trustee in bankruptcy, assignee for the benefit of creditors, secured party or other like Person believed in good faith by the Issuing Lender to be lawfully entitled to the property of such beneficiary, and the Issuing Lender may make payments under such Letter of Credit to such Person. For greater certainty, the preceding sentence is for the sole benefit of the Issuing Lender and the other Finance Parties, and may not be relied on by any other Person.

(4) No acts or omissions of any current or prior beneficiary of a Letter of Credit shall in any way affect or impair the rights of the Issuing Lender to enforce any right, power or benefit under this Agreement.

(5) Each Letter of Credit, except as specifically provided therein, and subject to any provision hereof to the contrary, shall be subject to the Uniform Customs and Practice for Documentary Credits or the International Standby Practices, as applicable, of the International Chamber of Commerce, as in effect at the time of issuance of the Letter of Credit.

5.06 Responsibility of Issuing Lender to Other Lenders

It is expressly understood and agreed that the obligations of the Issuing Lender hereunder to the other Lenders are only those expressly set forth in this Agreement and that the Issuing Lender shall be entitled to assume that the conditions precedent set forth in ARTICLE 6 have been satisfied unless it shall have acquired actual

- 49 -

knowledge that any such condition precedent has not been satisfied.

5.07 Participation in Sanger LC Payment Obligations

(1) Each Lender, shall be deemed to have purchased, without recourse, a risk participation from the Sanger Lender in the Sanger LC Payment Advance Obligations, in each case in an amount equal to its pro rata share of the Sanger LC Payment Advance Obligations (based on the respective Commitments of the Lenders) and shall absolutely, unconditionally and irrevocably assume, as primary obligor and not as surety, and be obligated to pay and discharge when due, its pro rata share of the Sanger LC Payment Advance Obligations. The obligation of a Lender to make a Sanger LC Payment Advance in accordance with its pro rata share of the Sanger LC Payment Advance Obligations shall be absolute and unconditional and shall not be affected by the occurrence of a Default, an Event of Default or any other occurrence or event. On the date that each Sanger LC Payment Advance is to be made pursuant to a Sanger LC Payment Advance Obligation, the Borrower shall be deemed to have requested, under the Revolving Credit, a US Base Rate Loan in the amount, and as of the due date, of such Sanger LC Payment Advance and the Sanger Lender shall promptly advise the Administrative Agent in writing of the obligation of the Lenders to make such Sanger LC Payment Advance rateably under the Revolving Credit.

(2) Each Lender hereby irrevocably agrees to make its pro rata share of each US Base Rate Loan deemed to have been requested under the Revolving Credit pursuant to Section 5.07(1) immediately upon any such deemed request in the amount, and as of the date specified in Section 5.07(1) notwithstanding (i) the amount of the Loan may not comply with the requirements hereunder, (ii) whether any conditions specified herein are then satisfied, (iii) whether a Default or an Event of Default then exists, (iv) that any such request or deemed request for a Loan is not made by the time otherwise required hereunder, (v) whether the date of such Borrowing is a date on which Loans are otherwise permitted to be made hereunder or (vi) any termination of the Commitments relating thereto at any time prior to or contemporaneously with such Borrowing. In the event that any such Loan cannot for any reason be made on the date otherwise required above (including, without limitation, as a result of the commencement of any insolvency proceeding under any Applicable Laws with respect to any APCO Entities), then each Lender shall promptly purchase (as of the date such Borrowing would otherwise have occurred, but adjusted for any payments received from the Borrower on or after such date and prior to such purchase) from the Sanger Lender such participation in the outstanding Sanger LC Payment Advances as shall be necessary to cause each such Lender to share in such Sanger LC Payment Advances rateably (based upon the

- 50 -

respective Commitment of the Lenders (determined before giving effect to any termination of the Commitments pursuant to Section 10.02)), provided that at the time any purchase of a participation pursuant to this sentence is actually made, the purchasing Lender shall be required to pay to the Sanger Lender, to the extent not paid to Sanger Lender by the Borrower, interest on the principal amount of the participation purchased for each day from and including the day upon which such Borrowing would otherwise have occurred to but excluding the date of payment for such participation, at a rate equal to the Interbank Rate.

Enforce any and all Liens and other rights and interests created and existing under the Documents and all rights of set-off.

(2) Notwithstanding the foregoing, if an Event of Default specified in Section 10.01(k) or 10.01(l) shall occur, then the Commitments shall automatically terminate and all Obligations owing to the Administrative Agent or any Lenders hereunder shall automatically and immediately become and be due and payable without the giving of any notice or other action by the Administrative Agent or any Lenders.

10.03   Remedies Not Exclusive

The Borrower expressly agrees that the rights and remedies of the Finance Parties under the Documents are cumulative and in addition to, and not in substitution for, any other rights or remedies. Any single or partial exercise by the Administrative Agent or any Lenders of any rights or remedies for a default or breach of any term, covenant, condition or agreement under any Documents shall not constitute or be deemed a waiver of or alter, affect or prejudice any other rights or remedies to which the Administrative Agent or any Lenders may be lawfully entitled for the same default or breach. Any waiver by the Administrative Agent or any Lenders of the strict observance of, performance of or compliance with any term, covenant, condition or agreement under any Documents and any indulgence granted, either expressly or by course of conduct, by the Administrative Agent or any Lenders shall be effective only in the specific instance and for the purpose given and shall not constitute or be deemed a waiver of any other rights or remedies of the Administrative Agent or any Lenders as a result of any other default.

ARTICLE 12

THE AGENT AND THE LENDERS

12.01   Authorization and Action

(1) Each Lender irrevocably appoints and authorizes the Administrative Agent to take such actions as agent on its behalf and to exercise such powers under this Agreement as are delegated to it by the terms of this Agreement, and such other powers as are reasonably incidental thereto which it may be necessary for the Administrative Agent to exercise in order for the provisions of the Documents to be carried out. As to any matters not expressly provided for by this Agreement, the Administrative Agent shall act or refrain from acting (and shall be fully protected in so doing) upon the joint instructions of the Majority Lenders which instructions shall be binding upon all Lenders. The Administrative Agent shall not be required to take any action pursuant to

- 81 -

such instructions or otherwise which (i) exposes it to personal liability, (ii) is contrary to this Agreement or Applicable Laws, (iii) would require the Administrative Agent to become registered to do business in any jurisdiction, or (iv) would subject the Administrative Agent to taxation. Each Lender acknowledges and agrees that, prior to the termination of the Commitments and the repayment in full of all Obligations (other than those Obligations arising under any Continuing Secured Hedging Agreements), no Lender may take independent legal action to enforce any obligation of the Borrower or any other Obligor hereunder (any such action to be taken by the Administrative Agent upon the decision of the Majority Lenders). Each Lender hereby acknowledges that, prior to the termination of the Commitments and the repayment in full of all Obligations (other than those Obligations arising under any Continuing Secured Hedging Agreements) and to the extent permitted by Applicable Law, the Security Documents and the remedies provided thereunder to the Lenders are for the benefit of the Administrative Agent and Lenders collectively and acting together and not severally, and further acknowledges that, prior to the termination of the Commitments and the repayment in full of all Obligations (other than those Obligations arising under any Continuing Secured Hedging Agreements), each Lender’s rights hereunder and under the Security Documents are to be exercised collectively, not severally, by the Administrative Agent upon the decision of the Majority Lenders.

(2) The Administrative Agent has no duties or obligations other than as expressly set out in this Agreement. Nothing contained herein shall be construed or is intended to impose any other duties (including fiduciary duties) or obligations on the Administrative Agent. The Administrative Agent may execute or perform, and may delegate the execution and performance of, any of its powers, rights, duties or discretion under the Documents through or to any Persons designated by it and references in any Document to the Administrative Agent shall be deemed to include any such Persons.

(3) The Administrative Agent is not obliged to (i) take or refrain from taking any action or exercise or refrain from exercising any right or discretion under the Documents, or (ii) incur or subject itself to any cost in connection with the Documents, unless it is first specifically indemnified or furnished with security by the Lenders on a rateable basis, in form and substance satisfactory to the Administrative Agent (which may include further agreements of indemnity or the deposit of funds or security).

(4) The Administrative Agent shall promptly deliver to each Lender any notices, reports or other communications contemplated under this Agreement and intended for the benefit of the Lenders.

12.02   No Liability

Neither the Administrative Agent nor its directors, officers, agents or employees shall be liable to any Lender for any action taken or omitted to be taken by it or them in connection with the Documents except for its or their own gross negligence or wilful misconduct. Without limiting the generality of the foregoing, the Administrative

- 82 -

Agent (i) may treat any Lender as the payee of amounts attributable to the Lender’s Commitments unless and until the Administrative Agent receives an agreement in the form contemplated in Section 13.10, (ii) may consult with legal counsel (including legal counsel for the Borrower), independent accountants and other experts selected by it and shall not be liable for any action taken or omitted to be taken by it in accordance with their advice, (iii) makes no representation or warranty to any Lender and shall not be responsible to any Lender for the form, substance, accuracy or completeness of any Document or any other documents or information made available to the Lenders, or for any statements, representations or warranties made in connection with this Agreement or any other Documents, (iv) has no duty to inspect the property (including books and records) of the Borrower or any other Person, (v) has no duty to ascertain or enquire as to the existence of a Default or an Event of Default or the observance of any of the terms or conditions of the Documents, (vi) is not responsible to any Lender for the execution, validity, enforceability, genuineness, sufficiency or value of any of the Documents or any Collateral, and (vii) shall incur no liability by acting upon any notice, consent, certificate or other instrument believed by it to be genuine and signed or sent by the proper Person.

12.03   Accommodations by Administrative Agent

With respect to its Commitment and the Advances made by it in its capacity as a Lender, the Administrative Agent has the same rights and powers under this Agreement as any other Lender and may exercise such rights and powers as though it were not the Administrative Agent. The term “Lender” or “Lenders” shall, unless otherwise expressly indicated, include the Administrative Agent in its individual capacity. The Administrative 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, any APUC Entities, any Related Parties or any Person who may do business with or own securities of such Persons, all as if it were not the Administrative Agent and without any duty to account to the Lenders.

12.04   Security and Payments

(1) The Security Documents shall be held by the Administrative Agent for its benefit as Administrative Agent and the rateable benefit of the Lenders and any proceeds from any realization of the Security Documents shall be applied in payment of outstanding Obligations in accordance with Section 2.09 (whether such Security Documents are held in the name of the Administrative Agent or in the name of any one or more of the Lenders and without regard to any priority to which any Lender may otherwise be entitled under Applicable Laws).

(2) Without prejudice to the foregoing, each Lender hereby irrevocably appoints and authorizes National Bank of Canada (and any successor acting as Administrative Agent) to act as the person holding the power of attorney (fondé de pouvoir) (in such capacity “Attorney”) of the Lenders as contemplated under Article 2692 of the Civil Code of Quebec, and to enter into, to take and to hold on their behalf,

- 83 -

and for their benefit, any hypothec, and to exercise such powers and duties which are conferred upon the Attorney under any hypothec and the Administrative Agent agrees to act in such capacity. Moreover, without prejudice to such appointment and authorization to act as the person holding the power of attorney as aforesaid, each Lender hereby irrevocably appoints and authorizes National Bank of Canada (and any successor acting as Administrative Agent) (in such capacity, the “Custodian”) to act as agent and custodian for and on behalf of the Lenders to hold and to be the sole registered holder of any bond which may be issued under any hypothec, the whole notwithstanding Section 32 of the Act respecting the special powers of legal persons (Quebec) or any other Applicable Law. In this respect (i) the Custodian shall keep a record indicating the names and addresses of, and the pro rata portion of the Obligations secured by any pledge of any such bond and owing to each Lender, and (ii) each Lender will be entitled to the benefits of any Collateral covered by any hypothec and will participate in the proceeds of realization of any such Collateral, the whole in accordance with the terms hereof.

(3) Each of the Attorney and the Custodian shall (i) have the sole and exclusive right and authority to exercise, except as may be otherwise specifically restricted by the terms hereof, all rights and remedies given to the Attorney and the Custodian (as applicable) pursuant to any hypothec, bond, pledge, Applicable Law or otherwise, (ii) benefit from and be subject to all provisions hereof with respect to the Administrative Agent, mutatis mutandis, including, all such provisions with respect to the liability or responsibility to and indemnification by the Lenders, and (iii) be entitled to delegate from time to time any of its powers or duties under any hypothec, bond, or pledge on such terms and conditions as it may determine from time to time.

(4) Any Person who becomes a Lender shall be deemed to have consented to and confirmed (i) the Attorney as the person holding the power of attorney as aforesaid and to have ratified, as of the date it becomes a Lender, all actions taken by the Attorney in such capacity, and (ii) the Custodian as the agent and custodian as aforesaid and to have ratified, as of the date it becomes a Lender, all actions taken by the Custodian in such capacity.

(5) Each Lender agrees with the other Lenders that it will not, without the prior consent of the other Lenders, take or obtain any Lien on any present or after-acquired undertaking or property of any Obligors to secure payment or performance of any obligations of any Obligors under any Documents, except for the benefit of all Lenders or as may otherwise be required by law.

(6) If any Lender obtains any payment (whether voluntary, involuntary or through the exercise of any right of set-off or realization of any Security Documents) on account of Advances made by the Lender (other than amounts paid pursuant to Section 13.06) in excess of its rateable share of payments obtained by all the Lenders, the Lender shall account to and pay over to the other Lenders their rateable share and shall,

- 84 -

upon request, immediately purchase from the other Lenders such participations in the Advances made by the other Lenders as shall be necessary to cause the purchasing Lender to share the excess payment rateably with the other Lenders. If all or any portion of the excess payment is recovered from the purchasing Lender, the purchase price shall be rescinded and each Lender shall repay to the purchasing Lender the purchase price to the extent of the recovery together with an amount equal to the Lender’s rateable share (according to the proportion that the amount the Lender’s required repayment bears to the total amount recovered from the purchasing Lender) of any interest or other amount paid by the purchasing Lender in respect of the total amount recovered. The Lender purchasing a participation from another Lender pursuant to this Section may, to the fullest extent permitted by law, but subject to Section 13.11, exercise all of its rights of payment (including any right of set-off) with respect to such participation as fully as if the Lender where a direct creditor of the Borrower in the amount of the participation and the Borrower expressly acknowledge the creation of such right.

12.05   Credit Decisions

Each Lender acknowledges that it has, independently and without reliance upon the Administrative Agent, made its own credit analysis and decision to enter into this Agreement. Each Lender also acknowledges that it will, independently and without reliance upon the Administrative Agent, and based on such documents and information as it shall deem appropriate at the time, continue to make its own credit decisions in taking or not taking action under this Agreement.

12.06   Indemnification

Each Lender shall indemnify and save the Administrative Agent harmless (to the extent not reimbursed by the Obligors) rateably from any Claim or Loss suffered by, imposed upon or asserted against the Administrative Agent as a result of, or arising out of, the Documents or any action taken or omitted by the Administrative Agent under the Documents provided that no Lender shall be liable for any part of a Claim or Loss resulting from the gross negligence or wilful misconduct of the Administrative Agent, in its capacity as agent. Without limiting the foregoing, each Lender shall reimburse the Administrative Agent upon demand for its rateable share of any out-of-pocket expenses incurred by the Administrative Agent in connection with the preparation, execution, administration or enforcement of, or legal advice in respect of any rights or responsibilities under the Documents (to the extent not reimbursed by the Obligors).

12.07   No Implied Liability to Other Lenders

Except as otherwise expressly provided in this Agreement, none of the Lenders has or shall have any duty or obligation, or shall in any way be liable to any other Lenders in respect of any Documents or any actions taken or omitted to be taken in connection therewith.

- 85 -

12.08   Successor Administrative Agents

The Administrative Agent may resign at any time by giving written notice to the Lenders and the Borrower, such resignation to be effective upon the appointment of a successor Administrative Agent. Upon notice of a resignation, the Majority Lenders shall have the right to appoint a successor Administrative Agent from among the Lenders. If no successor Administrative Agent is appointed or has accepted the appointment within thirty days after the retiring Administrative Agent’s notice of resignation, then the retiring Administrative Agent shall, on behalf of the Lenders, appoint a bank, chartered under the Bank Act (Canada) and having a branch in Montreal, Quebec, as the successor Administrative Agent, unless an Event of Default has occurred and is continuing, in which case, the retiring Administrative Agent may appoint any Person as the successor Administrative Agent. Upon the acceptance by a successor Administrative Agent of its appointment, the successor Administrative Agent shall succeed to and become vested with all the rights, powers, privileges and duties of the retiring Administrative Agent and the retiring Administrative Agent shall be discharged from its duties and obligations under this Agreement. After any retiring Administrative Agent’s resignation, the provisions of this Article shall enure to its benefit as to any actions taken or omitted to be taken by it while it was the Administrative Agent under this Agreement.

12.09   Secured Hedging Agreements

Notwithstanding that the Obligations under any Secured Hedging Agreement are secured by the Liens granted under and pursuant to the Security Documents, prior to the termination of all Commitments and the repayment in full of all Obligations, other than those Obligations arising under any Secured Hedging Agreements, all decisions regarding the administration and enforcement of the Security Documents shall be made by the Administrative Agent and Majority Lenders, and any Administrative Agent or Lender which is also a counterparty under any Secured Hedging Agreement shall not, in its capacity as a counterparty under any Secured Hedging Agreement, have any voting rights under this Agreement and no other right whatsoever to participate in any decisions regarding the administration or enforcement of the Security Documents. After termination of all Commitments and repayment in full of all Obligations other than any Obligations arising under and pursuant to the Secured Hedging Agreements, all decisions regarding the administration and enforcement of the Security Documents shall be made by the Administrative Agent on instructions from any Lender with exposure owed under and pursuant to any Continuing Secured Hedging Agreement (as defined in Section 12.10).

12.10   Continuing Secured Hedging Agreements

If, after the Maturity Date, the termination of all Commitments and the repayment in full of all CDN Prime Rate Loans, US Base Rate Loans, LIBOR Loans, Bankers Acceptances and Letters of Credit and any other Obligations under and pursuant hereto (but not including any amounts owing under any Secured Hedging Agreements which are not

- 86 -

terminated on and as of the Maturity Date), any Obligations under and pursuant to any Secured Hedging Agreements which are not, by their terms or otherwise, terminated on and as of the Maturity Date (the “Continuing Secured Hedging Agreements”) remain outstanding, the Administrative Agent may resign at any time by giving written notice to the Lenders with Continuing Secured Hedging Agreements, such resignation to be effective immediately upon the appointment of a successor Administrative Agent. Upon delivery of such a notice of resignation, the Lenders holding 66% of the exposure owed under and pursuant to the Continuing Secured Hedging Agreements shall appoint a successor Administrative Agent from among the Lenders that are counterparty to a Continuing Secured Hedging Agreement. Upon the appointment of the successor Administrative Agent, the successor Administrative Agent shall succeed to and become vested with all the rights, powers, privileges and duties of the retiring Administrative Agent under and pursuant to the Security Documents and the retiring Administrative Agent shall be discharged from its duties and obligations under such Security Documents.

13.03   Evidence of Indebtedness and Borrowing Notices

(1) The Indebtedness of the Borrower resulting from Advances under the Credit shall be evidenced by the records of the Lenders (or the Administrative Agent acting on behalf of the Lenders) which shall constitute prima facie evidence of such indebtedness.

A certificate as to amounts due pursuant to this Section 13.06(2), submitted in good faith by the Lender to the Borrower shall be conclusive and binding for all purposes, absent manifest error.

(3) The Borrower shall pay to each Lender on demand any amounts required to compensate the Lender for any Loss suffered or incurred by it as a result of (i) any payment being made (due to acceleration of the maturity of any Advance pursuant to ARTICLE 10, a mandatory or optional prepayment of principal or otherwise) in respect of a Bankers’ Acceptance or LIBOR Loan, other than on maturity or on the last day of a LIBOR Period applicable to the Loan, as the case may be, (ii) the failure of the Borrower to give any notice in the manner and at the times required by this Agreement, (iii) the failure of the Borrower to effect a Borrowing in the manner and at the time specified in any Borrowing Notice, or (iv) the failure of the Borrower to make a payment or a mandatory repayment in the manner and at the time specified in this Agreement.

(1) All payments to a Finance Party by the Borrower under any of the Documents shall be made free and clear of and without deduction or withholding for any Indemnified Taxes, unless such Indemnified Taxes are required by Applicable Laws to be deducted or withheld. If the Borrower shall be required by Applicable Laws to deduct or withhold any Indemnified Taxes (“Withholding Taxes”) from or in respect of

- 91 -

any amount payable under any of the Documents, (i) the amount payable shall be increased (and for greater certainty, in the case of interest, the amount of interest shall be increased) as may be necessary so that after making all required deductions or withholdings (including deductions or withholdings applicable to any additional amounts paid under this Section), the Finance Party receives an amount equal to the amount it would have received if no such deduction or withholding had been made, (ii) the Borrower shall make such deductions or withholdings, and (iii) the Borrower shall immediately pay the full amount deducted or withheld to the relevant Governmental Authority in accordance with Applicable Laws.

(2) The Borrower agrees to immediately pay any present or future stamp or documentary Taxes or any other similar Taxes (all such Taxes being collectively referred to as “Document Taxes”) which arise from any payment made by the Borrower under any Documents or from the execution, delivery or registration of, or otherwise with respect to, any Documents.

The provisions of Sections 13.06, 13.07 and 13.08 shall survive the termination of this Agreement. The Borrower acknowledges that neither its obligation to indemnify nor any actual indemnification by it of any Finance Party or any other Indemnified Person under this Agreement in respect of their Losses for legal fees and expenses shall in any way affect the confidentiality or privilege relating to any information communicated by the Indemnified Person to their counsel.

(a) except if an Event of Default has occurred and is continuing or in the case of an assignment of the entire remaining amount of the assigning Lender’s Commitment and the Advances at the time owing to it or in the case of an assignment to a Lender or an Affiliate of a Lender or an Approved Fund with respect to a Lender, the aggregate amount of the Commitment being assigned (which for this purpose includes Advances outstanding thereunder) or, if the applicable Commitment is not then in effect, the principal outstanding balance of the Advances of the assigning Lender subject to each such assignment (determined as of the date the Assignment and Assumption with respect to such assignment is delivered to the Administrative Agent or, if “Trade Date” is specified in the Assignment and Assumption, as of the Trade Date) shall not be less than $5,000,000, unless each of the Administrative Agent and, so long as no Event of Default has occurred and is continuing, the Borrower otherwise consents to a lower amount (each such consent not to be unreasonably withheld or delayed);

(b) each partial assignment shall be made as an assignment of a proportionate part of all the assigning Lender’s rights and obligations under this Agreement with respect to the Advance or the Commitment assigned;

(c) any assignment of a Commitment must be approved by the Issuing Lender (such approval not to be unreasonably withheld or delayed) unless the Person that is the proposed assignee is itself already a Lender;

(d) any assignment must be approved by the Administrative Agent (such approval not to be unreasonably withheld or delayed) unless:

(i) the proposed assignee is itself already a Lender, or

- 93 -

(ii) the proposed assignee is a bank whose senior, unsecured, non-credit enhanced, long term debt is rated at least A3, A- or A low by at least two of Moody’s Investor Services Inc., Standard & Poor’s, a division of The McGraw-Hill Companies, Inc. and Dominion Bond Rating Service Limited, respectively;

(e) any assignment must be approved by the Borrower (such approval not to be unreasonably withheld or delayed) unless the proposed assignee is itself already a Lender or an Event of Default has occurred and is continuing; and

(f) the parties to each assignment shall execute and deliver to the Administrative Agent an Assignment and Assumption, together with a processing and recordation fee in the amount of $5,000 and the Eligible Assignee, if it shall not be a Lender, shall deliver to the Administrative Agent an Administrative Questionnaire.

Subject to acceptance and recording thereof by the Administrative Agent pursuant to subsection (3) of this Section, from and after the effective date specified in each Assignment and Assumption, the Eligible Assignee thereunder shall be a party to this Agreement and, to the extent of the interest assigned by such Assignment and Assumption, have the rights and obligations of a Lender under this Agreement and the other Documents, including the Security Documents, and the assigning Lender thereunder shall, to the extent of the interest assigned by such Assignment and Assumption, be released from its obligations under this Agreement (and, in the case of an Assignment and Assumption covering all of the assigning Lender’s rights and obligations under this Agreement, such Lender shall cease to be a party hereto) but shall continue to be entitled to the benefits of Sections 13.06, 13.07 and 13.08 and shall continue to be liable for any breach of this Agreement by such Lender, with respect to facts and circumstances occurring prior to the effective date of such assignment. Any assignment or transfer by a Lender of rights or obligations under this Agreement that does not comply with this Section 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 subsection (4) of this Section. Any payment by an assignee to an assigning Lender in connection with an assignment or transfer shall not be or be deemed to be a repayment by the Borrower or a new Advance to the Borrower.

(3) Register

The Administrative Agent shall maintain at one of its offices in Toronto, Ontario a copy of each Assignment and Assumption 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 Advances owing to, each Lender pursuant to the terms hereof from time to time (the “Register”). The entries in the Register shall be conclusive, absent manifest error, and the Borrower and the Finance Parties may treat each Person whose

- 94 -

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 Borrower and any Lender, at any reasonable time and from time to time upon reasonable prior notice.

(4) Participations

Subject to the following sentence, any Lender may at any time, without the consent of, or notice to, the Borrower or the Administrative Agent, sell participations to any Person (each, a “Participant”) in any rights or obligations of the Lender under this Agreement (including any of its Commitment or any Advances owing to it), provided that (i) the Lender’s obligations under this Agreement shall remain unchanged, (ii) the Lender shall remain solely responsible to the other parties hereto for the performance of such obligations; and (iii) the Borrower, the Administrative Agent and the other Lenders shall continue to deal solely and directly with the Lender in connection with the Lender’s rights and obligations under this Agreement. The sale of a participation at a time when no Event of Default has occurred and is continuing shall require the consent of, and notice to, the Borrower and the Administrative Agent, unless the Participant is a bank or other financial institution. Any payment by a Participant to a Lender in connection with a sale of a participation shall not be or be deemed to be a repayment by the Borrower or a new Advance to the Borrower.

Subject to subsection (5) of this Section, the Borrower agree that each Participant shall be entitled to the benefits of Sections 13.06, 13.07 and 13.08 to the same extent as if it were a Lender and had acquired its interest by assignment pursuant to subsection (2) of this Section. To the extent permitted by law, each Participant also shall be entitled to the benefits of Section 13.11 as though it were a Lender, provided such Participant agrees to be subject to Section 12.04(6) as though it were a Lender.

(5) Limitations upon Participant Rights

A Participant shall not be entitled to receive any greater payment under Sections 13.06(2) or 13.08 than the relevant Lender would have been entitled to receive with respect to the participation sold to such Participant, unless the sale of the participation to such Participant is made with the Borrower’ prior written consent.

(6) Certain Pledges

Any Lender may at any time pledge or assign a security interest in all or any portion of its rights under this Agreement to secure obligations of the Lender, but no such pledge or assignment shall release the Lender from any of its obligations hereunder or substitute any such pledgee or assignee for the Lender as a party hereto. The Borrower shall, and shall cause each of the other Obligors to, execute and deliver all such further agreements, instruments and documents, and do all such further acts and things, as any assigning Lender may reasonably require to give effect to an Assignment.

- 95 -

13.11   Right of Set-off

Upon the occurrence and during the continuance of any Event of Default, each Lender is authorized at any time and from time to time, to the fullest extent permitted by Applicable Laws, 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 it to or for the credit or the account of the Borrower against any and all of the obligations of the Borrower under any of the Documents. Each Lender shall promptly notify the Borrower of any set-off and application made by the Lender, provided that the failure to give such notice shall not affect the validity of the set-off and application. The rights of each Lender under this Section are in addition to the other rights and remedies (including all other rights of set-off) which the Lender may have.

13.12   Judgment Currency

(1) In the event that for purposes of obtaining judgment in a court, it is necessary to convert any amount due to the Administrative Agent or any Lender in any currency (the “Original Currency”) into another currency (the “Other Currency”), the parties agree, to the fullest extent that they may effectively do so, that the rate of exchange used shall be that at which, in accordance with normal banking procedures, the Administrative Agent could purchase the Original Currency with the Other Currency on the Business Day preceding the day on which final judgment is given or, if permitted by Applicable Laws, on the day on which the judgment is paid or satisfied.

(2) The obligations of an Obligor to pay any amount due in the Original Currency to the Administrative Agent or any Lender (the “Payee”) under any Documents shall, notwithstanding any judgment in any Other Currency, be discharged only to the extent that on the Business Day following receipt by the Payee of any sum adjudged to be so due in the Other Currency, the Payee may, in accordance with normal banking procedures, purchase the Original Currency with the Other Currency. If the amount of the Original Currency so purchased is less than the amount originally due to the Payee in the Original Currency, the Obligor agrees, as a separate obligation and notwithstanding the judgment, to indemnify the Payee, against any loss, and, if the amount of the Original Currency so purchased exceeds the amount originally due to the Payee in the Original Currency, the Payee shall remit such excess to the Obligor.

13.13   Interest on Overdue Amounts Generally

Except as may be otherwise expressly provided in this Agreement, all amounts owed by the Borrower or any other Obligor to the Administrative Agent or any Lender, which are not paid when due (whether at stated maturity, on demand, by acceleration or otherwise) shall bear interest (after default and judgment), from the date on which such amount is due until such amount is paid in full, payable on demand, at a rate per annum equal at all times to (i) in the case of an amount payable in US Dollars, the interest rate applicable to a US Base Rate Loan plus 2% per annum, and (ii) in the

- 96 -

case of an amount payable in Canadian Dollars, the rate of interest applicable to a Canadian Prime Rate Loan plus 2% per annum.

13.14   Survival

Notwithstanding anything else contained herein, the provisions of Article 12 and Sections 13.06, 13.07 and 13.08 (and all other provisions of this Agreement which are necessary to give effect to each of the provisions of such Articles) shall survive the termination of the Commitments until the repayment in full of all Obligations (including all Obligations under any Continuing Secured Hedging Agreements); provided that after the repayment in full of all Obligations other than those Obligations under the Continuing Secured Hedging Agreements, the provisions of such Articles (other than those that survive pursuant to Sections 5.09 and 13.09 (which shall survive in accordance with such sections)) shall continue for the benefit of those Lenders that are counterparty to a Continuing Secured Hedging Agreement.

13.15   Governing Law

This Agreement shall be governed by and construed in accordance with the laws of the Province of Ontario and the laws of Canada applicable therein. Notwithstanding the previous sentence, the appointment of the Attorney contemplated by Section 12.04 hereto shall be governed by the laws of the Province of Quebec.

13.16   Most Favored Lender Provision

(1) If the governing documentation for any Refinancing Debt Issue, including any amendments thereto (and the Borrower agrees to provide the Administrative Agent with a copy of any such amendment within five Business Days of the effectiveness thereof) contains, at any time, any (i) financial covenant or maintenance test (including any other comparable measure of financial performance or condition, however expressed), (ii) negative or restrictive covenant or (iii) event of default, and such covenant or event of default is not contained in this agreement in substantially equivalent form or is more restrictive on any Obligor or would be more beneficial to the Lenders than the analogous covenant or event of default set forth in this Agreement (any such covenant or event of default, an “Additional Covenant”), all as determined by the Majority Lenders, acting reasonably, then upon written notice from the Administrative Agent to the Borrower specifying any such Additional Covenant, such Additional Covenant (including any necessary corresponding definitions) shall be deemed automatically incorporated into this Agreement, mutatis mutandis, as if set forth fully herein, without any further action required on the part of any Person, effective as of the date when such Additional Covenant became effective under the relevant Refinancing Debt Issue; provided that any such notice has been provided to the Borrower within 20 Business Days of the delivery to the Administrative Agent of the governing documentation for the relevant Refinancing Debt Issue. Notwithstanding the foregoing, the provisions of this Section 13.16 shall not apply to include terms and conditions

- 97 -

applicable in respect of any Refinancing Debt Issue relating to the rate of interest or payment of fees charged or payable thereunder or other “administrative” matters.

(2) Any Additional Covenant incorporated into this Agreement pursuant to this Section 13.16 (i) shall remain unchanged herein notwithstanding any subsequent waiver of such covenant under the Refinancing Debt Issues, (ii) provided that no Event of Default is then in existence, shall be deemed automatically amended herein to reflect any subsequent amendments agreed and implemented in relation to such Additional Covenant under the Refinancing Debt Issues and (iii) shall be deemed deleted from this Agreement at such time as such Additional Covenant is deleted or otherwise eliminated from the Refinancing Debt Issues or the Refinancing Debt Issues facility and all commitments thereunder are terminated and no amounts are outstanding thereunder.

(3) The breach of any Additional Covenant incorporated into this Agreement pursuant to this Section 13.16 shall constitute an Event of Default under and pursuant to this Agreement, and the period of grace (if any) applicable to the breach of such Additional Covenant in the Refinancing Debt Issues shall apply hereunder. Certificates delivered to the Administrative Agent in respect of Section 9.03 shall include the information (including detailed calculations) required in order to establish whether the Borrower and/or APUC, as applicable, was in compliance with each Additional Covenant that is a financial covenant and is incorporated into this Agreement pursuant to this Section 13.16.

(4) Upon the request of the Administrative Agent, acting reasonably, the Borrower and other Obligors shall enter into any additional agreement or amendment to this Agreement reasonably requested evidencing any of the foregoing.
