2.2Defined Terms

Section 1.1 of the Credit Agreement is hereby amended by adding the following definitions of “Swingline Lender” and “Swingline Loan” immediately after the existing definition of “Order”:

“Swingline Lender” means The Bank of Nova Scotia or any other Lender with an Individual Commitment selected by the Agent and acceptable to the Borrower who assumes in writing the obligation of making Swingline Loans on behalf of the Lenders.

“Swingline Loan” shall have the meaning ascribed thereto in Section 3.15.

2.3Increase of Credit Facility

Section 2.6 of the Credit Agreement is hereby amended by (x) deleting “and” at the end of paragraph (d), (y) deleting “.” at the end of paragraph (e) and replacing it with “; and” and (z) adding the following new paragraph (f) after the existing paragraph (e):

2

“(f)The Agent shall forthwith advise the Swingline Lender of its receipt of an Accordion Notice.  In the event that a bank that is not an existing Lender is to become a Lender in accordance with Section 2.6(a), such bank must be approved by the Swingline Lender, in its reasonable discretion, and the Swingline Lender shall notify the Agent whether or not it approves of such new Lender within ten Business Days of the Swingline Lender’s receipt of such notice.”.

2.4Swingline Loans

The Credit Agreement is hereby amended by adding the following new Section 3.15 immediately after the existing Section 3.14:

“3.15Swingline Loans.

Subject to the following provisions of this Section, overdrafts on the accounts of the Borrower maintained with the Agent shall be deemed to be outstanding as an extension of credit to the Borrower from the Swingline Lender under the Credit Facility (each, a “Swingline Loan”) as follows:

(i)in the case of overdrafts in Canadian dollars, as Prime Rate Loans; and

(ii)in the case of overdrafts in United States dollars, as Base Rate Canada Loans.

For certainty, notwithstanding Section 4.1, no Drawdown Notice need be delivered by the Borrower in respect of Swingline Loans:

(a)Except as otherwise specifically provided herein, all references to Prime Rate Loans and Base Rate Canada Loans shall include Swingline Loans made in Canadian and United States dollars, respectively.

(b)Swingline Loans shall be made by the Swingline Lender alone, without assignment to or participation by the other Lenders.

(c)The aggregate principal amount of the Swingline Loans shall not exceed $15,000,000 or the U.S. Dollar Equivalent thereof.

(d)If the Borrower shall request a drawdown under the Credit Facility other than under this Section 3.15 (a “Syndicated Drawdown”) and the Swingline Lender’s Pro Rata Share of such Syndicated Drawdown would cause the Swingline Lender’s Pro Rata Share of all Syndicated Loans together with the Swingline Loans then outstanding to exceed the Swingline Lender’s Individual Commitment then the Borrower shall be deemed to have given a repayment notice notifying the Agent of a repayment of the Swingline Loans to the extent of such excess (without any bonus or penalty being payable in respect thereof) and the Borrower shall make such repayment on the requested date of such Syndicated Drawdown. 

3

For the purposes hereof “Syndicated Loans” means all credit outstanding under the Credit Facility other than Swingline Loans.

(e)The Borrower may make repayments of Swingline Loans (together with accrued interest thereon) by deposit to the applicable account of the Borrower from time to time without penalty.

(f)All interest payments and principal repayments of or in respect of Swingline Loans shall be solely for the account of the Swingline Lender.  Subject to Section 3.15(h), all costs and expenses relating to the Swingline Loans shall be solely for the account of the Swingline Lender.

(g)Notwithstanding anything to the contrary herein contained or contrary to the provisions of Law, (a) if an Event of Default occurs and is continuing or (b) if the Swingline Lender so requires, and there are then outstanding any Swingline Loans, then, effective on the day of notice to that effect to the other Lenders with Individual Commitments from the Swingline Lender, the Borrower shall be deemed to have requested, and hereby requests, an extension of credit by way of drawdown of an amount of Syndicated Loans, in the currency or currencies of the Swingline Loans, sufficient to repay the Swingline Loans and accrued and unpaid interest in respect thereof, and on the day of receipt of such notice, each of the other relevant Lenders shall disburse to the Swingline Lender its respective Pro Rata Share of such amounts and such amounts shall thereupon be deemed to have been advanced by the relevant Lenders to the Borrower and to constitute Syndicated Loans (by way of Base Rate Canada Loans if the Swingline Loans were so denominated or Prime Rate Loans if the Swingline Loans were so denominated, or both).  Such Syndicated Loans shall be deemed to be comprised of principal and accrued and unpaid interest in the same proportions as the corresponding Swingline Loans.  If a relevant Lender does not disburse to the Swingline Lender its respective Pro Rata Share of any amount under this Section 3.15(g) then, for the purpose only of any distributions or payments to such Lenders (and not, for greater certainty, for purposes of any obligations of such Lenders, including those under Section 14.10), including any distribution or payment with respect to the Borrower in the event of any enforcement or realization proceedings or any bankruptcy, winding-up, liquidation, arrangement, compromise or composition, the Individual Commitment of such Lender shall be deemed to be nil and the Individual Commitment of the Swingline Lender shall be increased by the Individual Commitment of such Lender until the amounts owed by the Borrower are outstanding to each relevant Lender in accordance with its Pro Rata Share determined without regard to this sentence.  If any amount disbursed by a relevant Lender to the Swingline Lender under this Section 3.15(g) and deemed to have been advanced to the Borrower must be repaid by the Swingline Lender or by the relevant Lender to the Borrower then no reduction of the Swingline Loans as contemplated above shall be deemed to have occurred, but the relevant Lenders shall purchase participations in the Swingline Loans (without

4

recourse to the Swingline Lender) for an amount or otherwise effect transactions to achieve the financial results contemplated by this Section.

(h)For certainty, it is hereby acknowledged and agreed that the Lenders shall be obligated to advance their Pro Rata Share of an extension of credit by way of drawdown contemplated by Section 3.15(g) and to disburse to the Swingline Lender their Pro Rata Shares of the Syndicated Loan referenced therein irrespective of:

(i)whether a Default or Event of Default is then continuing or whether any other condition in Article 12 is met; and

(ii)whether or not the Borrower has in fact actually requested such extension of credit by way of drawdown (by delivery of a Drawdown Notice or otherwise).”.

2.5Affirmative Covenants — Prompt Payments

2.8SCHEDULE D — FORM OF ASSIGNMENT
