For the purposes of disclosure under the Interest Act (Canada), if and to the extent applicable, whenever interest is to be paid hereunder and such interest is to be calculated on the basis of a period of less than a calendar year, the yearly rate of interest to which the rate determined pursuant to such calculation is equivalent is the rate so determined multiplied by the actual number of days in the calendar year in which the same is to be ascertained and divided by the number of days in such period.

Section 1.3 Limitation on Interest.

If any provision of this Agreement or of any of the other Loan Documents would obligate any Credit Party to make any payment of interest or other amount payable to the Lenders in an amount or calculated at a rate which would be prohibited by law or would result in a receipt by the Lenders of interest at a criminal rate (as such terms are construed under the Criminal Code (Canada)) then, notwithstanding such provisions, such amount or rate shall be deemed to have been adjusted with retroactive effect to the maximum amount or rate of interest, as the case may be, as would not be so prohibited by law or so result in a receipt by the Lenders of interest at a criminal rate, such adjustment to be effected, to the extent necessary, as follows: (1) firstly, by reducing the amount or rate of interest required to be paid to the Lenders, and (2) thereafter, by reducing any fees, commissions, premiums and other amounts required to be paid to the Lenders which would constitute “interest” for purposes of Section 347 of the Criminal Code (Canada). Notwithstanding the foregoing, and after giving effect to all adjustments contemplated thereby, if the Lenders shall have received an amount in excess of the maximum permitted by that section of the Criminal Code (Canada), the Credit Parties shall be entitled, by notice in writing to the Agent, to obtain reimbursement from the Lenders in an amount equal to such excess and, pending such reimbursement, such amount shall be deemed to be an amount payable by the Lenders to the Borrower. Any amount or rate of interest referred to in this Section 1.3 shall be determined in accordance with generally accepted actuarial practices and principles as an effective annual rate of interest over the term that the applicable Credit remains outstanding on the assumption that any charges, fees or expenses that fall within the meaning of “interest” (as defined in the Criminal Code (Canada)) shall, if they relate to a specific period of time, be pro- rated over that period of time and otherwise be pro-rated over the period from the Effective Date to the applicable maturity date, and, in the event of a dispute, a certificate of a Fellow of the Canadian Institute of Actuaries appointed by the Agent shall be conclusive absent manifest error for the purposes of such determination.

Section 1.4 Currency Calculations

For purposes of preparing the Collateral Coverage Certificate, financial statements, calculating financial covenants and determining compliance with covenants expressed in Dollars, Canadian Dollars or Euros shall be converted to Dollars on a weighted average in accordance with GAAP.

Section 1.5 Accounting Terms and Determinations

Unless otherwise specified herein, all accounting terms used herein shall be interpreted, all accounting determinations hereunder (including without limitation determinations made pursuant to the exhibits hereto) shall be made, and all financial statements required to be

delivered hereunder shall be prepared on a consolidated basis in accordance with GAAP applied on a basis consistent with the most recent audited consolidated financial statements of the Borrower and its Subsidiaries delivered to Agent and each of the Lenders. If at any time any change in GAAP , including the adoption into GAAP or otherwise of the International Financial Reporting Standards, or in the application thereof, would affect the computation of any financial ratio or financial requirement set forth in any Loan Document, and the Borrower or the Majority Lenders shall so request, the Agent, the Lenders and the Borrower shall negotiate in good faith to amend such ratio or requirement to preserve the original intent thereof in light of such change in GAAP (subject to the approval of the Majority Lenders); provided that, until so amended, (i) such ratio or requirement shall continue to be computed in accordance with GAAP prior to such change therein and (ii) the Borrower shall provide to the Agent and the Lenders financial statements and other documents required under this Agreement which include a reconciliation between calculations of such ratio or requirement made before and after giving effect to such change in GAAP. All amounts used for purposes of financial calculations required to be made herein shall be without duplication. Notwithstanding any other provision contained herein, all terms of an accounting or financial nature used herein shall be construed, and all computations of amounts and ratios referred to herein shall be made, without giving effect to any election under Statement of Financial Accounting Standards 159 (or any other Financial Accounting Standard having a similar result or effect) to value any Indebtedness or other liabilities of any Loan Party at “fair value”, as defined therein.

ARTICLE 2 — REVOLVING CREDIT.

Section 2.1 Commitment

Subject to the terms and conditions of this Agreement (including without limitation Section 2.4 hereof), each Revolving Credit Lender severally and for itself alone agrees to make Advances of the Revolving Credit in Dollars to the Borrower from time to time on any Business Day during the period from the Effective Date hereof until (but excluding) the Revolving Credit Maturity Date in an aggregate amount, not to exceed at any one time outstanding such Lender’s Revolving Credit Percentage of the Revolving Credit Aggregate Commitment. Subject to the terms and conditions set forth herein, advances, repayments and readvances may be made under the Revolving Credit.

Section 2.2 Commitment Increase

(1) Commitment Increase. The Borrower may, at any time and from time to time, but not more frequently than twice annually, add additional financial institutions as Lenders under this Agreement and/or, by agreement with any existing Lender, increase the Revolving Credit Commitment Amount of such existing Lender, and the Revolving Credit Aggregate Commitment shall thereby be increased by the amounts of the Revolving Credit Commitment Amount of any such additional Lenders and/or the amounts of the increases in the Revolving Credit Commitment Amount of any such existing Lenders, provided that:

(a) No Default or Event of Default shall have occurred and be continuing at the time of any such addition of a new Lender and/or increase in the Revolving Credit Commitment Amount of an existing Lender;

(b) After giving effect to any such addition of a new Lender and/or increase in the Revolving Credit Commitment Amount of an existing Lender, the Revolving Credit Aggregate Commitment shall not be greater than US$60,000,000;

(c) The Agent, Issuing Lender and Swing Line Lender shall have consented, acting reasonably, to the identity and allocation of any such new Lender or to the allocation to any existing Lender resulting in an increased Revolving Credit Commitment Amount to such Lender;

(d) Any fees or other compensation payable to a new Lender (including facility or upfront fees) shall not be greater (in absolute terms or as a percentage) than the equivalent fees or other compensation paid to the existing Lenders in connection with their Commitments;

(e) The Borrower shall have delivered to the Agent:

(i) A certificate signed by a Responsible Person on behalf of the Borrower, effective as of the date of the increase in the Revolving Credit Aggregate Commitment as contemplated herein, confirming and certifying (A) the accuracy of the statement in (a) above, (B) the resolutions of the Credit Parties and all other authorizations necessary to authorize the increase in the Revolving Credit Aggregate Commitment in the manner contemplated herein and the execution, delivery and performance by the Credit Parties of all Loan Documents required to give effect to same and the transactions contemplated thereby, and (C) no Governmental Approvals or other consents, approvals or authorizations of any other Person are required for such increase in the Revolving Credit Aggregate Commitment (except as have been obtained and are in full force and effect); and

(ii) Such Loan Documents as the Agent may reasonably require to give effect to the increase in the Revolving Credit Aggregate Commitment, together with a legal opinion of counsel for the Credit Parties satisfactory to the Agent with respect to any Loan Document executed in connection with the increase in the Revolving Credit Aggregate Commitment and any Loan Documents executed in connection therewith.

For greater certainty, any Lender that becomes a party to this Agreement in accordance with this Section 2.2 shall be a “Lender” under this Agreement and shall have all of the rights and obligations of a “Lender” under this Agreement and the other Loan Documents.

(2) Adjustments Between Lenders. Subject to the following sentence of this Section 2.2(2), concurrent with the addition of any financial institution as a new Lender or the increase in the Revolving Credit Commitment Amount of any existing Lender, such new Lender or existing Lender shall purchase from each other Lender such portion of the outstanding Indebtedness owed to each such other Lender as may be determined by the Agent, acting reasonably, as is necessary, to ensure that the outstanding Indebtedness owed to all Lenders (including any such new Lender) are in accordance with the Revolving Credit Percentage of the Lenders and any such new Lender shall execute such documentation as is required by the Agent, acting reasonably, to incorporate such new Lender as a Lender under, and upon and subject to all

the terms and conditions of, this Agreement. Notwithstanding the foregoing, (a) there shall not be any purchases made or indemnifications given in respect of any Eurodollar-based Advance, BBA LIBOR-Advance or CDOR-based Advance outstanding at the time of the increase in the Revolving Credit Aggregate Commitment, however if any Advance or repayment is made prior to the end of the applicable Interest Period or Contract Period of any such any Eurodollar-based Advance, BBA LIBOR-Advance or CDOR-based Advance, the Agent will make adjustments between the Lenders so as to ensure that the outstanding Indebtedness owed to all Lenders (including any such new Lender) are as near as practicable in accordance with the Revolving Credit Percentages of the Lenders (given that such Eurodollar-based Advances, BBA LIBOR- Advances or CDOR-based Advances remain outstanding), and (b) provided that any request for an additional financial institution as a Lender or an increase in the Revolving Credit Agreement Commitment may not be made after the first anniversary of the Effective Date. Nothing in this Section 2.2(2) shall obligate any Lender to make available borrowings in excess of its Revolving Credit Commitment Amount at any time.

Section 2.3 Accrual of Interest and Maturity; Evidence of Indebtedness.

(1) The Borrower hereby unconditionally promises to pay to the Agent for the account of each Revolving Credit Lender the then unpaid principal amount of each Revolving Credit Advance (plus all accrued and unpaid interest) of such Revolving Credit Lender to the Borrower on the Revolving Credit Maturity Date and on such other dates and in such other amounts as may be required from time to time pursuant to this Agreement. Subject to the terms and conditions hereof, each Revolving Credit Advance shall, from time to time from and after the date of such Advance (until paid), bear interest at its Applicable Interest Rate.

(2) Each Revolving Credit Lender shall maintain in accordance with its usual practice an account or accounts evidencing indebtedness of the Borrower to the appropriate lending office of such Revolving Credit Lender resulting from each Revolving Credit Advance made by such lending office of such Revolving Credit Lender from time to time, including the amounts of principal and interest payable thereon and paid to such Revolving Credit Lender from time to time under this Agreement.

(3) The Agent shall maintain the Register pursuant to Section 12.8(6), and a subaccount therein for each Revolving Credit Lender, in which Register and subaccounts (taken together) shall be recorded (i) the amount of each Revolving Credit Advance made hereunder, the type thereof and each Euro-Interest Period applicable to any Eurodollar-based Advance or BBA LIBOR-based Advance or Contract Period applicable to any CDOR-based Advance, (ii) the amount of any principal or interest due and payable or to become due and payable from the Borrower to each Revolving Credit Lender hereunder in respect of the Revolving Credit Advances and (iii) both the amount of any sum received by the Agent hereunder from the Borrower in respect of the Revolving Credit Advances and each Revolving Credit Lender’s share thereof.

(4) The entries made in the Register maintained pursuant to paragraph (c) of this Section 2.3 shall, absent manifest error, to the extent permitted by applicable law, be prima facie evidence of the existence and amounts of the obligations of the Borrower therein recorded; provided, however, that the failure of any Revolving Credit Lender or the Agent to maintain the Register or any account, as applicable, or any error therein, shall not in any manner affect the obligation of

the Borrower to repay the Revolving Credit Advances (and all other amounts owing with respect thereto) made to the Borrower by the Revolving Credit Lenders in accordance with the terms of this Agreement.

(5) The Borrower agrees that, upon written request to the Agent by any Revolving Credit Lender, the Borrower will execute and deliver, to such Revolving Credit Lender, at the Borrower’s own expense, a Revolving Credit Note evidencing the outstanding Revolving Credit Advances owing to such Revolving Credit Lender.

Section 2.4 Requests for and Refundings and Conversions of Advances

The Borrower may request an Advance of the Revolving Credit, a refund of any Revolving Credit Advance in the same type of Advance or to convert any Revolving Credit Advance to any other type of Revolving Credit Advance only by delivery to the Agent of a Request for Revolving Credit Advance executed by an Authorized Signer for the Borrower, subject to the following:

(2) each such Request for Revolving Credit Advance shall be delivered to the Agent by 12:00 p.m. (Toronto time) three (3) Business Days prior to the proposed date of the Revolving Credit Advance, except in the case of a US Base Rate Advance or a Canadian Prime Rate Advance, for which the Request for Revolving Credit Advance must be delivered by 12:00 p.m. (Toronto time) on the proposed date for such Revolving Credit Advance;

(6) a Request for Revolving Credit Advance, once delivered to the Agent, shall not be revocable by the Borrower and shall constitute a certification by the Borrower as of the date thereof that:

(b) there is no Default or Event of Default in existence, and none will exist upon the making of such Revolving Credit Advance (both before and immediately after giving effect to such Revolving Credit Advance); and

The Agent, acting on behalf of the Revolving Credit Lenders, may also, at its option, lend under this Section 2.4 upon the telephone or email request of an Authorized Signer of the Borrower to make such requests and, in the event the Agent, acting on behalf of the Revolving Credit Lenders, makes any such Advance upon a telephone or email request, an Authorized Signer shall fax or deliver by electronic file to the Agent, on the same day as such telephone or email request, an executed Request for Revolving Credit Advance. The Borrower hereby authorizes the Agent to disburse Advances under this Section 2.4 pursuant to the telephone or email instructions of any person purporting to be an Authorized Signer. Notwithstanding the foregoing, the Borrower acknowledges that the Borrower shall bear all risk of loss resulting from disbursements made upon any telephone or email request. Each telephone or email request for an Advance from an Authorized Signer for the Borrower shall constitute a certification of the matters set forth in the Request for Revolving Credit Advance form as of the date of such requested Advance.

Section 2.5 Disbursement of Advances.

(1) Upon receiving any Request for Revolving Credit Advance from the Borrower under Section 2.4 hereof, the Agent shall promptly notify each Revolving Credit Lender by electronic mail, facsimile, wire, telex or telephone (confirmed by electronic mail, facsimile, wire, telecopy or telex) of the amount of such Advance being requested and the date such Revolving Credit Advance is to be made by each Revolving Credit Lender in an amount equal to its Revolving Credit Percentage of such Advance. Unless such Revolving Credit Lender’s commitment to make Revolving Credit Advances hereunder shall have been suspended or terminated in accordance with this Agreement, each such Revolving Credit Lender shall make available the amount of its Revolving Credit Percentage of each Revolving Credit Advance in immediately available funds to the Agent, as follows:

(a) for US Base Rate Advances, not later than 4:00 p.m. (Toronto time) on the date of such Revolving Credit Advance, by credit to an account of the Borrower maintained with the Agent or to such other account or third party as the Borrower may reasonably direct in writing, provided such direction is timely given;

(b) for Canadian Prime Rate Advances or CDOR-based Advances, not later than 4:00 p.m. (Toronto time) on the date of such Revolving Credit Advance, by credit to an account of the Borrower maintained with the Agent or to such other account or third party as the Borrower may direct, provided such direction is timely given; and

(3) The Agent shall deliver the documents and papers received by it for the account of each Revolving Credit Lender to such Revolving Credit Lender. Unless the Agent shall have been notified by any Revolving Credit Lender prior to the date of any proposed Revolving Credit

Advance that such Revolving Credit Lender does not intend to make available to the Agent such Revolving Credit Lender’s Percentage of such Advance, the Agent may assume that such Revolving Credit Lender has made such amount available to the Agent on such date, as aforesaid. The Agent may, but shall not be obligated to, make available to the Borrower the amount of such payment in reliance on such assumption. If such amount is not in fact made available to the Agent by such Revolving Credit Lender, as aforesaid, the Agent shall be entitled to recover such amount on demand from such Revolving Credit Lender. If such Revolving Credit Lender does not pay such amount forthwith upon the Agent’s demand therefor and the Agent has in fact made a corresponding amount available to the Borrower, the Agent shall promptly notify the Borrower and the Borrower shall pay such amount to the Agent, if such notice is delivered to the Borrower prior to 3:00 p.m. (Toronto time) on a Business Day, on the day such notice is received, and otherwise on the next Business Day, and such amount paid by the Borrower shall be applied as a prepayment of the Revolving Credit (without any corresponding reduction in the Revolving Credit Aggregate Commitment), reimbursing the Agent for having funded said amounts on behalf of such Revolving Credit Lender. The Borrower shall retain its claim against such Revolving Credit Lender with respect to the amounts repaid by it to the Agent and, if such Revolving Credit Lender subsequently makes such amounts available to the Agent, the Agent shall promptly make such amounts available to the Borrower as a Revolving Credit Advance. The Agent shall also be entitled to recover from such Revolving Credit Lender or the Borrower, as the case may be, but without duplication, interest on such amount in respect of each day from the date such amount was made available by the Agent to the Borrower, to the date such amount is recovered by the Agent, at a rate per annum equal to:

(a) in the case of such Revolving Credit Lender, for the first two (2) Business Days such amount remains unpaid, the Federal Funds Effective Rate, and thereafter, at the rate of interest then applicable to such Revolving Credit Advances; and

(b) in the case of the Borrower, the rate of interest then applicable to such Advance of the Revolving Credit.

Until such Revolving Credit Lender has paid the Agent such amount, such Revolving Credit Lender shall have no interest in or rights with respect to such Advance for any purpose whatsoever. The obligation of any Revolving Credit Lender to make any Revolving Credit Advance hereunder shall not be affected by the failure of any other Revolving Credit Lender to make any Advance hereunder, and no Revolving Credit Lender shall have any liability to the Borrower or any of its Subsidiaries, the Agent, any other Revolving Credit Lender, or any other party for another Revolving Credit Lender’s failure to make any loan or Advance hereunder.

The entries made in such account or accounts of Swing Line Lender shall be prima facie evidence, absent manifest error, of the existence and amounts of the obligations of the Borrower therein recorded; provided, however, that the failure of Swing Line Lender to maintain such account, as applicable, or any error therein, shall not in any manner affect the obligation of the Borrower to repay the Swing Line Advances (and all other amounts owing with respect thereto) in accordance with the terms of this Agreement.

(b) The Borrower agrees that, upon the written request of Swing Line Lender, the Borrower will execute and deliver to Swing Line Lender a Swing Line Note.

(5) Refunding of or Participation Interest in Swing Line Advances.

(a) The Agent, at any time in its sole and absolute discretion, may, in each case on behalf of the Borrower (which hereby irrevocably directs the Agent to act on their behalf) request each of the Revolving Credit Lenders (including the Swing Line Lender in its capacity as a Revolving Credit Lender) to make an Advance of the Revolving Credit to the Borrower, in an amount equal to such Revolving Credit Lender’s Revolving Credit Percentage of the aggregate principal amount of the Swing Line Advances outstanding on the date such notice is given (the “Refunded Swing Line Advances”). The applicable Revolving Credit Advances used to refund any Swing Line Advances shall be US Base Rate Advances. In connection with the making of any such Refunded Swing Line Advances or the

purchase of a participation interest in Swing Line Advances under Section 2.6(5)(b) hereof, the Swing Line Lender shall retain its claim against the Borrower for any unpaid interest or fees in respect thereof accrued to the date of such refunding. Unless any of the events described in Section 8.1(i) hereof shall have occurred (in which event the procedures of Section 2.6(5)(b) shall apply) and regardless of whether the conditions precedent set forth in this Agreement to the making of a Revolving Credit Advance are then satisfied (but subject to Section 2.6(5)(b)), each Revolving Credit Lender shall make the proceeds of its Revolving Credit Advance available to the Agent for the benefit of the Swing Line Lender at the office of the Agent specified in Section 2.5(1) hereof prior to 11:00 a.m. (Toronto time) on the Business Day next succeeding the date such notice is given, in immediately available funds.

Each Revolving Credit Lender within the time periods specified in Section 2.6(5)(a) hereof, as applicable, shall immediately transfer to the Agent, for the benefit of the Swing Line Lender, in immediately available funds, an amount equal to its Revolving Credit Percentage of the aggregate principal amount of all Swing Line Advances outstanding as of such date.

(c) Each Revolving Credit Lender’s obligation to make Revolving Credit Advances to refund Swing Line Advances, and to purchase participation interests, in accordance with Section 2.6(5)(a) and Section 2.6(5)(b), respectively, shall be absolute and unconditional and shall not be affected by any circumstance, including, without limitation, (A) any set-off, counterclaim, recoupment, defense or other right which such Revolving Credit Lender may have against Swing Line Lender, the Borrower or any other Person for any reason whatsoever; (B) the occurrence or continuance of any Default or Event of Default; (C) any adverse change in the condition (financial or otherwise) of the Borrower or any other Person; (D) any breach of this Agreement or any other Loan Document by the Borrower or any other Person; (E) any inability of the Borrower to satisfy the conditions precedent to borrowing set forth in this Agreement on the date upon which such Revolving Credit Advance is to be made or such participating interest is to be purchased; (F) the termination of the Revolving Credit Aggregate Commitment hereunder; or (G) any other circumstance, happening or event whatsoever, whether or not similar to any of the foregoing.

The obligation of any Revolving Credit Lender to make available its pro rata portion of the amounts required pursuant to Section 2.6(5)(a) and Section 2.6(5)(b) hereof shall not be affected by the failure of any other Revolving Credit Lender to make such amounts available, and no Revolving Credit Lender shall have any liability to any Credit Party, the Agent, the Swing Line Lender, or any other Revolving Credit Lender or any other party for another Revolving Credit Lender’s failure to make available the amounts required under Section 2.6(5)(a) and Section 2.6(5)(b) hereof.

(d) Notwithstanding the foregoing, no Revolving Credit Lender shall be required to make any Revolving Credit Advance to refund a Swing Line Advance or to purchase a participation in a Swing Line Advance if at least two (2) Business Days prior to the making of such Swing Line Advance by the Swing Line Lender, the officers of the Swing Line Lender immediately responsible for matters concerning this Agreement shall have received written notice from the Agent or any Lender that Swing Line Advances should be suspended based on the occurrence and continuance of a Default or Event of Default and stating that such notice is a “notice of default”; provided, however that the obligation of the Revolving Credit Lenders to make or refund such Swing Line Advance or purchase a participation in such Swing Line Advance) shall be reinstated upon the date on which such Default or Event of Default has been waived by the requisite Lenders.

Section 2.7 Hedging Transactions

Upon receipt thereof, the Agent will deliver to such Revolving Credit Lender a participation certificate evidencing its participation interest in respect of such payment and expenses. To the extent that a Revolving Credit Lender fails to make such amount available to the Agent by 11:00 a.m. (Toronto time) on the Business Day next succeeding the date such notice is given, such Revolving Credit Lender shall pay interest on such amount in respect of each day from the date such amount was required to be paid, to the date paid to the Agent, at a rate per annum equal to the Federal Funds Effective Rate. The failure of any Revolving Credit Lender to make its pro rata portion of any such amount available to the Agent shall not relieve any other Revolving Credit Lender of its obligation to make available its pro rata portion of such amount, but no Revolving Credit Lender shall be responsible for failure of any other Revolving Credit Lender to make such pro rata portion available to the Agent.

(5) In the case of any Advance made under Section 3.7(3), each such Advance shall be disbursed notwithstanding any failure to satisfy any conditions for disbursement of any Advance set forth in Article 2 hereof or Article 4 hereof, and, to the extent of the Advance so disbursed, the Reimbursement Obligation of the Borrower to the Agent under Section 3.7(3) shall be deemed satisfied (unless, in each case, taking into account any such deemed Advances, the aggregate outstanding principal amount of Advances of the Revolving Credit and the Swing Line, plus the Letter of Credit Obligations (other than the Reimbursement Obligations to be reimbursed by this Advance), plus the Hedging Obligations on such date exceed the then applicable Revolving Credit Aggregate Commitment).

(6) If the Issuing Lender shall honour a draft or other demand for payment presented or made under any Letter of Credit, the Issuing Lender shall provide notice thereof to the Borrower on the date such draft or demand is honoured, and to each Revolving Credit Lender on such date unless the Borrower shall have satisfied its reimbursement obligations by payment to the Agent (for the benefit of the Issuing Lender) as required under this Section 3.7. The Issuing Lender shall further use reasonable efforts to provide notice to the Borrower prior to honouring any such draft or other demand for payment, but such notice, or the failure to provide such notice, shall not affect the rights or obligations of the Issuing Lender with respect to any Letter of Credit or the rights and obligations of the parties hereto, including without limitation the obligations of the Borrower under this Section 3.7.

(7) Notwithstanding the foregoing however no Revolving Credit Lender shall be deemed to have acquired a participation in a Letter of Credit if the officers of the Issuing Lender immediately responsible for matters concerning this Agreement shall have received written notice from the Agent or any Lender at least two (2) Business Days prior to the date of the issuance or extension of such Letter of Credit or, with respect to any Letter of Credit subject to automatic extension, at least five (5) Business Days prior to the date that the beneficiary under such Letter of Credit must be notified that such Letter of Credit will not be renewed, that the issuance or extension of Letters of Credit should be suspended based on the occurrence and continuance of a Default or Event of Default and stating that such notice is a “notice of default”; provided, however that the Revolving Credit Lenders shall be deemed to have acquired such a participation upon the date on which such Default or Event of Default has been waived by the requisite Revolving Credit Lenders, as applicable. In the event that the Issuing Lender receives such a notice, the Issuing Lender shall have no obligation to issue any Letter of Credit until such notice is withdrawn by the Agent or such Lender or until the requisite Lenders have waived such Default or Event of Default in accordance with the terms of this Agreement.

(8) Nothing in this Agreement shall be construed to require or authorize any Revolving Credit Lender to issue any Letter of Credit, it being recognized that the Issuing Lender shall be the sole issuer of Letters of Credit under this Agreement.

(9) In the event that any Revolving Credit Lender becomes a Defaulting Lender, the Issuing Lender may, at its option, require that the Borrower enter into arrangements satisfactory to Issuing Lender to eliminate the Fronting Exposure with respect to the participation in the Letter of Credit Obligations by such Defaulting Lender, including creation of a cash collateral account on terms satisfactory to Agent or delivery of other security to assure payment of such Defaulting Lender’s Percentage of all outstanding Letter of Credit Obligations.

Section 3.8 Obligations Irrevocable

The obligations of Borrower to make payments to the Agent for the account of Issuing Lender or the Revolving Credit Lenders with respect to Letter of Credit Obligations under Section 3.7 hereof, shall be unconditional and irrevocable and not subject to any qualification or exception whatsoever, including, without limitation:

(a) Any lack of validity or enforceability of any Letter of Credit, any Letter of Credit Agreement, any other documentation relating to any Letter of Credit, this Agreement or any of the other Loan Documents (the “Letter of Credit Documents”);

(b) Any amendment, modification, waiver, consent, or any substitution, exchange or release of or failure to perfect any interest in collateral or security, with respect to or under any Letter of Credit Document;

(c) The existence of any claim, setoff, defense or other right which the Borrower may have at any time against any beneficiary or any transferee of any Letter of Credit (or any persons or entities for whom any such beneficiary or any such transferee may be acting), the Agent, the Issuing Lender or any Revolving Credit Lender or any other Person, whether in connection with this Agreement, any of the Letter of

Credit Documents, the transactions contemplated herein or therein or any unrelated transactions;

(d) Any draft or other statement or document presented under any Letter of Credit proving to be forged, fraudulent, invalid or insufficient in any respect or any statement therein being untrue or inaccurate in any respect, other than in respect of the gross negligence or wilful misconduct of the Issuing Lender;

(e) Payment by the Issuing Lender to the beneficiary under any Letter of Credit against presentation of documents which do not comply with the terms of such Letter of Credit, including failure of any documents to bear any reference or adequate reference to such Letter of Credit, other than in respect of the gross negligence or wilful misconduct of the Issuing Lender;

(f) Any failure, omission, delay or lack on the part of the Agent, Issuing Lender or any Revolving Credit Lender or any party to any of the Letter of Credit Documents or any other Loan Document to enforce, assert or exercise any right, power or remedy conferred upon the Agent, Issuing Lender, any Revolving Credit Lender or any such party under this Agreement, any of the other Loan Documents or any of the Letter of Credit Documents, or any other acts or omissions on the part of the Agent, Issuing Lender, any Revolving Credit Lender or any such party; or

(g) Any other event or circumstance that would, in the absence of this Section 3.8, result in the release or discharge by operation of law or otherwise of the Borrower from the performance or observance of any obligation, covenant or agreement contained in Section 3.7 hereof.

No setoff, counterclaim, reduction or diminution of any obligation or any defense of any kind or nature which the Borrower has or may have against the beneficiary of any Letter of Credit shall be available hereunder to the Borrower against the Agent, Issuing Lender or any Revolving Credit Lender. With respect to any Letter of Credit, nothing contained in this Section 3.8 shall be deemed to prevent the Borrower, after satisfaction in full of the absolute and unconditional obligations of the Borrower hereunder with respect to such Letter of Credit, from asserting in a separate action any claim, defense, set off or other right which they (or any of them) may have against the Agent, Issuing Lender or any Revolving Credit Lender in connection with such Letter of Credit.

In the administration of Letters of Credit, Issuing Lender shall not be liable for

Issuing Lender will, upon request, furnish the Revolving Credit Lenders with copies of Letter of Credit Documents related thereto.

(3) In connection with the issuance and administration of Letters of Credit and the assignments hereunder, Issuing Lender makes no representation and shall have no responsibility with respect to (i) the obligations of the Borrower or the validity, sufficiency or enforceability of any document or instrument given in connection therewith, or the taking of any action with respect to same, (ii) the financial condition of, any representations made by, or any act or omission of the Borrower or any other Person, or (iii) any failure or delay in exercising any rights or powers possessed by Issuing Lender in its capacity as issuer of Letters of Credit in the absence of its gross negligence or wilful misconduct.

If at any time any Revolving Credit Lender shall receive from any source whatsoever any payment on any such unreimbursed amount or interest thereon in excess of such Revolving Credit Lender’s Percentage of such payment, such Revolving Credit Lender will promptly pay over such excess to the Agent, for redistribution in accordance with this Agreement.

No Borrower shall be required to indemnify any L/C Indemnified Person for any L/C Indemnified Amounts to the extent such amounts result from the gross negligence or wilful misconduct of such L/C Indemnified Person or any officer, director, employee or agent of such L/C Indemnified Person and the Agent and the Issuing Lender shall be liable to the Borrower to the extent, but only to the extent, of any direct, as opposed to consequential or incidental, damages suffered by the Borrower which were caused by the gross negligence or wilful misconduct of the Issuing Lender or any officer, director, employee or agent of the Issuing Lender or by the Issuing Lender’s wrongful dishonour of any Letter of Credit after the presentation to it by the beneficiary thereunder of a draft or other demand for payment and other documentation strictly complying with the terms and conditions of such Letter of Credit.

(l) any Loan Document shall at any time for any reason cease to be in full force and effect (other than in accordance with the terms thereof or the terms of any other Loan Document), as applicable, or the validity, binding effect or enforceability thereof shall be contested by any party thereto (other than any Lender, the Agent, Issuing Lender or Swing Line Lender), or any Person shall deny that it has any or further liability or obligation under any Loan Document, or any such Loan Document shall be terminated (other than in accordance with the terms thereof or the terms of any other Loan Document), invalidated, revoked or set aside or in any way cease to give or provide to the Lenders and the Agent the benefits purported to be created thereby, or any Loan Document purporting to grant a Lien to secure any Indebtedness shall, at any time after the delivery of such Loan Document, fail to create a valid and enforceable Lien on any Collateral purported to be covered thereby or such Lien shall fail to cease to be a perfected Lien with the priority required in the relevant Loan Document.

Section 8.2 Exercise of Remedies

If an Event of Default has occurred and is continuing hereunder: (a) the Agent may, and shall, upon being directed to do so by the Majority Lenders, declare the Revolving Credit Aggregate Commitment terminated; (b) the Agent may, and shall, upon being directed to do so by the Majority Lenders, declare the entire unpaid principal Indebtedness, including the Notes, immediately due and payable, without presentment, notice or demand, all of which are hereby expressly waived by the Borrower; (c) upon the occurrence of any Event of Default specified in Section 8.1(i) and notwithstanding the lack of any declaration by the Agent under preceding clauses (a) or (b), the entire unpaid principal Indebtedness shall become automatically and immediately due and payable, and the Revolving Credit Aggregate Commitment shall be automatically and immediately terminated; (d) the Agent shall, upon being directed to do so by the Majority Lenders, demand immediate delivery of cash collateral, and the Borrower agrees to deliver such cash collateral upon demand, in an amount equal to 105% of the maximum amount that may be available to be drawn at any time prior to the stated expiry of all outstanding Letters of Credit, for deposit into an account controlled by the Agent; (e) the Agent may, and shall, upon being directed to do so by the Majority Lenders, notify the Borrower or any Credit Party that interest shall be payable on demand on all Indebtedness (other than Revolving Credit Advances with respect to which Section 2.6 hereof shall govern) owing from time to time to the Agent or any Lender, at a per annum rate equal to the then applicable US Base Rate or Canadian Prime Rate plus three percent (3%); and (f) the Agent may, and shall, upon being directed to do so by the Majority Lenders or the Lenders, as applicable (subject to the terms hereof), exercise any remedy permitted by this Agreement, the other Loan Documents or law.

Section 8.3 Rights Cumulative

No delay or failure of the Agent and/or Lenders in exercising any right, power or privilege hereunder shall affect such right, power or privilege, nor shall any single or partial exercise thereof preclude any further exercise thereof, or the exercise of any other power, right or

privilege. The rights of the Agent and Lenders under this Agreement are cumulative and not exclusive of any right or remedies which Lenders would otherwise have.

Section 8.4 Waiver by the Borrower of Certain Laws

To the extent permitted by applicable law, the Borrower hereby agrees to waive, and does hereby absolutely and irrevocably waive and relinquish the benefit and advantage of any valuation, stay, appraisement, extension or redemption laws now existing or which may hereafter exist, which, but for this provision, might be applicable to any sale made under the judgment, order or decree of any court, on any claim for interest on the Notes, or any security interest or mortgage contemplated by or granted under or in connection with this Agreement. These waivers have been voluntarily given, with full knowledge of the consequences thereof.

Section 8.5 Waiver of Defaults

No Event of Default shall be waived by the Lenders except in a writing signed by an officer of the Agent in accordance with Section 12.10 hereof. No single or partial exercise of any right, power or privilege hereunder, nor any delay in the exercise thereof, shall preclude other or further exercise of their rights by the Agent or the Lenders. No waiver of any Event of Default shall extend to any other or further Event of Default. No forbearance on the part of the Agent or the Lenders in enforcing any of their rights shall constitute a waiver of any of their rights. The Borrower expressly agrees that this Section may not be waived or modified by the Lenders or the Agent by course of performance, estoppel or otherwise.

Section 8.6 Set Off

Upon the occurrence and during the continuance of any Event of Default, each Lender may at any time and from time to time, without notice to the Borrower but subject to the provisions of Section 9.3 hereof (any requirement for such notice being expressly waived by the Borrower), setoff and apply against any and all of the obligations of the Borrower now or hereafter existing under this Agreement, whether owing to such Lender, any Affiliate of such Lender or any other Lender or the Agent, 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 such Lender to or for the credit or the account of the Borrower and any property of the Borrower from time to time in possession of such Lender, irrespective of whether or not such deposits held or indebtedness owing by such Lender may be contingent and unmatured and regardless of whether any Collateral then held by the Agent or any Lender is adequate to cover the Indebtedness. Promptly following any such setoff, such Lender shall give written notice to the Agent and the Borrower of the occurrence thereof. The Borrower hereby grants to the Lenders and the Agent a lien on and security interest in all such deposits, indebtedness and property as collateral security for the payment and performance of all of the obligations of the Borrower under this Agreement. The rights of each Lender under this Section 8.6 are in addition to the other rights and remedies (including, without limitation, other rights of setoff) which such Lender may have.

Section 8.7 Receiver

Upon the occurrence of an Event of Default, the Agent may, without notice or consent and without regard to the adequacy of any security for the Indebtedness, obtain appointment of a receiver, interim receiver or receiver manager for the business of the Borrower, the Collateral

(including, without limitation, the rents and profits derived from any Collateral), and the Borrower hereby consents to such appointment. This appointment will be in addition to any other rights, relief or remedies afforded the Agent and the Lenders. Such receiver, in addition to any other rights to which he is entitled, may sell any and all property of the Borrower for the benefit of the Agent and the Lenders pursuant to provisions of applicable law. The Agent may initiate receivership proceedings in any forum selected by Agent.

ARTICLE 9 — PAYMENTS, RECOVERIES AND COLLECTIONS.

Section 9.1 Payment Procedure

(1) All payments to be made by the Borrower shall be made without condition or deduction for any counterclaim, defense, recoupment or setoff. Except as otherwise provided herein, all payments made by the Borrower of principal, interest or fees hereunder shall be made without setoff or counterclaim on the date specified for payment under this Agreement and must be received by the Agent not later than 1:00 p.m. (Toronto time) on the date such payment is required or intended to be made in the applicable currency of such Advance being Dollars, CAD Dollars or EUR, as applicable, in immediately available funds to the Agent at the Agent’s office located at Suite 2210, South Tower, Royal Bank Plaza, 200 Bay Street, Toronto, Ontario M5J 2J2 for the ratable benefit of the Revolving Credit Lenders in the case of payments in respect of the Revolving Credit, any Letter of Credit Obligations and Hedging Obligations. Any payment received by the Agent after 1:00 p.m. (Toronto time) shall be deemed received on the next succeeding Business Day and any applicable interest or fee shall continue to accrue. Upon receipt of each such payment, the Agent shall make prompt payment to each applicable Lender in like funds and currencies, of all amounts received by it for the account of such Lender.

(2) Unless the Agent shall have been notified in writing by the Borrower at least two (2) Business Days prior to the date on which any payment to be made by the Borrower is due that the Borrower does not intend to remit such payment, the Agent may, in its sole discretion and without obligation to do so, assume that the Borrower has remitted such payment when so due and the Agent may, in reliance upon such assumption, make available to each Revolving Credit Lender, on such payment date an amount equal to such Lender’s share of such assumed payment. If the Borrower has not in fact remitted such payment to the Agent, each Lender shall forthwith on demand repay to the Agent the amount of such assumed payment made available or transferred to such Lender, together with the interest thereon, in respect of each day from and including the date such amount was made available by the Agent to such Lender to the date such amount is repaid to the Agent at a rate per annum equal to the Federal Funds Effective Rate for the first two (2) Business Days that such amount remains unpaid, and thereafter at a rate of interest then applicable to such Revolving Credit Advances.

(3) Subject to the definition of “Interest Period” in Article 1 of this Agreement, whenever any payment to be made hereunder shall otherwise be due on a day which is not a Business Day, such payment shall be made on the next succeeding Business Day and such extension of time shall be included in computing interest, if any, in connection with such payment.

(4) All payments to be made by the Borrower under this Agreement or any of the Notes (including without limitation payments under the Swing Line and/or Swing Line Note) shall be made without setoff or counterclaim, as aforesaid, and, subject to full compliance by each Lender (and each assignee and participant pursuant to Section 12.8) with Section 12.13, without

deduction for or on account of any present or future withholding or other taxes of any nature imposed by any Governmental Authority or of any political subdivision thereof or any federation or organization of which such Governmental Authority may at the time of payment be a member (other than any taxes on the overall income, net income, net profits or net receipts or similar taxes (or any franchise taxes imposed in lieu of such taxes) on the Agent or any Lender (or any branch maintained by the Agent or a Lender) as a result of a present or former connection between the Agent or such Lender and the Governmental Authority, political subdivision, federation or organization imposing such taxes), unless the Borrower is compelled by law to make payment subject to such tax. In such event, the Borrower shall:

(a) pay to the Agent for the Agent’s own account and/or, as the case may be, for the account of the Lenders such additional amounts as may be necessary to ensure that the Agent and/or such Lender or Lenders (including the Swing Line Lender) receive a net amount equal to the full amount which would have been receivable had payment not been made subject to such tax; and

(b) remit such tax to the relevant taxing authorities according to applicable law, and send to the Agent or the applicable Lender or Lenders (including the Swing Line Lender), as the case may be, such certificates or certified copy receipts as the Agent or such Lender or Lenders shall reasonably require as proof of the payment by the Borrower of any such taxes payable by the Borrower.

As used herein, the terms “tax”, “taxes” and “taxation” include all taxes, levies, imposts, duties, fees, deductions and withholdings or similar charges together with interest (and any taxes payable upon the amounts paid or payable pursuant to this Section 9.1) thereon. The Borrower shall be reimbursed by the applicable Lender for any payment made by the Borrower under this Section 9.1 if the applicable Lender is not in compliance with its obligations under Section 12.13 at the time of the Borrower’s payment.

Section 9.2 Application of Proceeds of Collateral

Notwithstanding anything to the contrary in this Agreement, in the case of any Event of Default under Section 8.1(i), immediately following the occurrence thereof, and in the case of any other Event of Default: (a) upon the termination of the Revolving Credit Aggregate Commitment, (b) the acceleration of any Indebtedness arising under this Agreement, (c) at the Agent’s option, or (d) upon the request of the Majority Lenders after the commencement of any remedies hereunder, the Agent shall apply the proceeds of any Collateral, together with any offsets, voluntary payments by any Credit Party or others and any other sums received or collected in respect of the Indebtedness first, to pay all incurred and unpaid fees and expenses of the Agent under the Loan Documents and any protective advances made by the Agent with respect to the Collateral under or pursuant to the terms of any Loan Document, next, to pay any fees and expenses owed to the Issuing Lender hereunder, next, to the Indebtedness under the Revolving Credit (including any Reimbursement Obligations), on a pro rata basis, next to any obligations owing by any Credit Party under any Hedging Agreements on a pro rata basis, next, to any other Indebtedness on a pro rata basis, and then, if there is any excess, to the Credit Parties, as the case may be.

Section 9.3 Pro-rata Recovery

If any Lender shall obtain any payment or other recovery (whether voluntary, involuntary, by application of setoff or otherwise) on account of principal of, or interest on, any of the Advances made by it, or the participations in Letter of Credit Obligations, Hedging Obligations or Swing Line Advances held by it in excess of its pro rata share of payments then or thereafter obtained by all Lenders upon principal of and interest on all such Indebtedness, such Lender shall purchase from the other Lenders such participations in the Revolving Credit, the Letter of Credit Obligations and/or Hedging Obligations held by them as shall be necessary to cause such purchasing Lender to share the excess payment or other recovery ratably in accordance with the applicable Percentages of the Lenders; provided, however, that if all or any portion of the excess payment or other recovery is thereafter recovered from such purchasing holder, the purchase shall be rescinded and the purchase price restored to the extent of such recovery, but without interest.

Section 9.4 Treatment of a Defaulting Lender; Reallocation of Defaulting Lender’s Fronting Exposure.

(1) The obligation of any Lender to make any Advance hereunder shall not be affected by the failure of any other Lender to make any Advance under this Agreement, and no Lender shall have any liability to the Borrower or any of their Subsidiaries, the Agent, any other Lender, or any other Person for another Lender’s failure to make any loan or Advance hereunder.

(2) If any Lender shall become a Defaulting Lender, then such Defaulting Lender’s right to vote in respect of any amendment, consent or waiver of the terms of this Agreement or such other Loan Documents, or to direct or approve any action or inaction by the Agent shall be subject to the restrictions set forth in Section 12.10.

(3) To the extent and for so long as a Lender remains a Defaulting Lender and notwithstanding the provisions of Section 9.3 hereof, the Agent shall be entitled, without limitation, (i) to withhold or setoff and to apply in satisfaction of those obligations for payment (and any related interest) in respect of which the Defaulting Lender shall be delinquent or otherwise in default to the Agent or any Lender (or to hold as cash collateral for such delinquent obligations or any future defaults) the amounts otherwise payable to such Defaulting Lender under this Agreement or any other Loan Document, (ii) if the amount of Advances made by such Defaulting Lender is less than its Percentage requires, apply payments of principal made by the Borrower amongst the Non-Defaulting Lenders on a pro rata basis until all outstanding Advances are held by all Lenders according to their respective Percentages and (iii) to bring an action or other proceeding, in law or equity, against such Defaulting Lender in a court of competent jurisdiction to recover the delinquent amounts, and any related interest. Performance by the Borrower of its obligations under this Agreement and the other Loan Documents shall not be excused or otherwise modified as a result of the operation of this Section, except to the extent expressly set forth herein. Furthermore, the rights and remedies of the Borrower, the Agent, the Issuing Lender, the Swing Line Lender and the other Lenders against a Defaulting Lender under this section shall be in addition to any other rights and remedies such parties may have against the Defaulting Lender under this Agreement or any of the other Loan Documents, applicable law or otherwise, and the Borrower does not waive any rights or remedies against any Defaulting Lender.

(4) If any Lender shall become a Defaulting Lender, then, for so long as such Lender remains a Defaulting Lender, any Fronting Exposure shall be reallocated by the Agent at the request of the Swing Line Lender and/or the Issuing Lender among the Non-Defaulting Lenders in accordance with their respective Percentages of the Revolving Credit, but only to the extent that the sum of the aggregate principal amount of all Revolving Credit Advances made by each Non- Defaulting Lender, plus such Non-Defaulting Lender’s Percentage of the aggregate outstanding principal amount of Swing Line Advances, Letter of Credit Obligations and Hedging Obligations prior to giving effect to such reallocation plus such Non-Defaulting Lender’s Percentage of the Fronting Exposure to be reallocated does not exceed such Non- Defaulting Lender’s Percentage of the Revolving Credit Aggregate Commitment, and only so long as no Default or Event of Default has occurred and is continuing on the date of such reallocation.

Section 9.5 Currency Matters

Principal, interest, reimbursement obligations, fees, and all other amounts payable under this Agreement and the other Loan Documents to the Agent and the Lenders shall be payable in the currency in which such Indebtedness is denominated. Unless stated otherwise, all calculations, comparisons, measurements or determinations under this Agreement shall be made in Dollars. For the purpose of such calculations, comparisons, measurements or determinations, amounts denominated in other currencies shall be converted to the Dollar Amount on the date of calculation, comparison, measurement or determination.

ARTICLE 10 — CHANGES IN LAW OR CIRCUMSTANCES; INCREASED COSTS.

Section 10.1 Reimbursement of Prepayment Costs

If (i) the Borrower makes any payment of principal with respect to any Eurodollar-based Advance or CDOR-based Advance on any day other than the last day of the Interest Period applicable thereto (whether voluntarily, pursuant to any mandatory provisions hereof, by acceleration, or otherwise); (ii) the Borrower converts or refunds (or attempts to convert or refund) any such Advance on any day other than the last day of the Interest Period applicable thereto (except as described in Section 2.6(5)); (iii) the Borrower fails to borrow, refund or convert any Eurodollar-based Advance or CDOR-based Advance after notice has been given by the Borrower to the Agent in accordance with the terms hereof requesting such Advance; or (iv) or if the Borrower fails to make any payment of principal in respect of a Eurodollar-based Advance or CDOR-based Advance when due, the Borrower shall reimburse the Agent for itself and/or on behalf of any Lender, as the case may be, within ten (10) Business Days of written demand therefor for any resulting loss, cost or expense incurred (excluding the loss of any Applicable Margin) by the Agent and Lenders, as the case may be, as a result thereof, including, without limitation, any such loss, cost or expense incurred in obtaining, liquidating, employing or redeploying deposits from third parties, whether or not the Agent and Lenders, as the case may be, shall have funded or committed to fund such Advance. The amount payable hereunder by the Borrower to the Agent for itself and/or on behalf of any Lender, as the case may be, shall be deemed to equal an amount equal to the excess, if any, of (a) the amount of interest which would have accrued on the amount so prepaid, or not so borrowed, refunded or converted, for the period from the date of such prepayment or of such failure to borrow, refund or convert, through the last day of the relevant Interest Period, at the applicable rate of interest for said Advance(s) provided under this Agreement, over (b) the amount of interest (as reasonably determined by the

Agent and Lenders, as the case may be) which would have accrued to the Agent and Lenders, as the case may be, on such amount by placing such amount on deposit for a comparable period with leading banks in the interbank eurodollar market. Calculation of any amounts payable to any Lender under this paragraph shall be made as though such Lender shall have actually funded or committed to fund the relevant Advance through the purchase of an underlying deposit in an amount equal to the amount of such Advance and having a maturity comparable to the relevant Interest Period or Contract Period, as applicable, provided, however, that any Lender may fund any Eurodollar-based Advance or CDOR-based Advance, as the case may be, in any manner it deems fit and the foregoing assumptions shall be utilized only for the purpose of the calculation of amounts payable under this paragraph. Upon the written request of the Borrower, the Agent and Lenders shall deliver to the Borrower a certificate setting forth the basis for determining such losses, costs and expenses, which certificate shall be conclusively presumed correct, absent manifest error.

Section 10.2 Circumstances Affecting LIBOR Rate, BBA LIBOR Rate or CDOR Rate Availability

If the Agent or the Majority Lenders (after consultation with the Agent) shall determine in good faith that, by reason of circumstances affecting the foreign exchange and interbank markets generally, deposits in eurodollars in the applicable amounts are not being offered to the Agent or such Lenders at the applicable LIBOR Rate, BBA LIBOR Rate or CDOR Rate, then the Agent shall forthwith give notice thereof to the Borrower. Thereafter, until the Agent notifies the Borrower that such circumstances no longer exist, (i) the obligation of Lenders to make Advances which bear interest at or by reference to the LIBOR Rate or CDOR Rate, and the right of the Borrower to convert an Advance to or refund an Advance as an Advance which bear interest at or by reference to the LIBOR Rate, BBA LIBOR Rate or CDOR Rate shall be suspended, (ii) effective upon the last day of each Euro-Interest Period or Contract Period, as applicable, related to any existing Eurodollar-based Advance, BBA LIBOR-based Advance or CDOR-Based Advance, each such Eurodollar-based Advance, BBA LIBOR-based Advance or CDOR-Based Advance shall automatically be converted into an Advance which bears interest at or by reference to the US Base Rate or Canadian Prime Rate, respectively (without regard to the satisfaction of any conditions to conversion contained elsewhere herein), and (iii) effective immediately following such notice, each Advance which bears interest at or by reference to the Daily Adjusting LIBOR Rate, BBA LIBOR Rate or CDOR Rate shall automatically be converted into an Advance which bears interest at or by reference to the US Base Rate or Canadian Prime Rate, respectively (without regard to the satisfaction of any conditions to conversion contained elsewhere herein).

Section 10.3 Laws Affecting LIBOR Rate, BBA LIBOR Rate or CDOR Rate Availability

If any Change in Law shall make it unlawful or impossible for any of the Lenders to honor its obligations hereunder to make or maintain any Advance which bears interest at or by reference to the LIBOR Rate, BBA LIBOR Rate or CDOR Rate, such Lender shall forthwith give notice thereof to the Borrower and to the Agent. Thereafter, (a) the obligations of the applicable Lenders to make Advances which bear interest at or by reference to the LIBOR Rate, BBA LIBOR Rate or CDOR Rate and the right of the Borrower to convert an Advance into or refund an Advance as an Advance which bears interest at or by reference to the LIBOR Rate, BBA LIBOR Rate or CDOR Rate shall be suspended and thereafter only the US Base Rate or

Canadian Prime Rate, as applicable, shall be available, and (b) if any of the Lenders may not lawfully continue to maintain an Advance which bears interest at or by reference to the LIBOR Rat, BBA LIBOR Rate e or CDOR Rate, the applicable Advance shall immediately be converted to an Advance which bears interest at or by reference to the US Base Rate or Canadian Prime Rate, as applicable.

Section 10.4 Increased Cost of Advances Carried at the LIBOR Rate, BBA LIBOR Rate or CDOR Rate

If any Change in Law shall:

(1) subject any of the Lenders to any tax, duty or other charge with respect to any Advance or shall change the basis of taxation of payments to any of the Lenders of the principal of or interest on any Advance or any other amounts due under this Agreement in respect thereof (except for changes in the rate of tax on the overall net income of any of the Lenders); or

(2) impose, modify or deem applicable any reserve (including, without limitation, any imposed by the Board of Governors of the Federal Reserve System), special deposit or similar requirement against assets of, deposits with or for the account of, or credit extended by, any of the Lenders or shall impose on any of the Lenders or the foreign exchange and interbank markets any other condition affecting any Advance;

and the result of any of the foregoing matters is to increase the costs to any of the Lenders of maintaining any part of the Indebtedness hereunder as an Advance which bears interest at or by reference to the LIBOR Rate, BBA LIBOR Rate or CDOR Rate or to reduce the amount of any sum received or receivable by any of the Lenders under this Agreement in respect of an Advance which bears interest at or by reference to the LIBOR Rate, BBA LIBOR Rate or CDOR Rate, then such Lender shall promptly notify the Agent, and the Agent shall promptly notify the Borrower of such fact and demand compensation therefor and, within ten (10) Business Days after such notice, the Borrower agrees to pay to such Lender or Lenders such additional amount or amounts as will compensate such Lender or Lenders for such increased cost or reduction, provided that each Lender agrees to take any reasonable action, to the extent such action could be taken without cost or administrative or other burden or restriction to such Lender, to mitigate or eliminate such cost or reduction, within a reasonable time after becoming aware of the foregoing matters. The Agent will promptly notify the Borrower of any event of which it has knowledge which will entitle Lenders to compensation pursuant to this Section, or which will cause the Borrower to incur additional liability under Section 10.1 hereof, provided that the Agent shall incur no liability whatsoever to the Lenders or the Borrower in the event it fails to do so. A certificate of the Agent (or such Lender, if applicable) setting forth the basis for determining such additional amount or amounts necessary to compensate such Lender or Lenders shall accompany such demand and shall be conclusively presumed to be correct absent manifest error.

Section 10.5 Capital Adequacy and Other Increased Costs

(1) If any Change in Law affects or would affect the amount of capital required to be maintained by a Lender or the Agent (or any corporation controlling such Lender or the Agent) and such Lender or the Agent, as the case may be, determines that the amount of such capital is increased by, or based upon the existence of such Lender’s or the Agent’s obligations or

Advances hereunder, the effect of such Change in Law is to result in such an increase, and such increase has the effect of reducing the rate of return on such Lender’s or the Agent’s (or such controlling corporation’s) capital as a consequence of such obligations or Advances hereunder to a level below that which such Lender or the Agent (or such controlling corporation) could have achieved but for such circumstances (taking into consideration its policies with respect to capital adequacy) by an amount deemed by such Lender or the Agent to be material (collectively, “Increased Costs”), then the Agent or such Lender shall notify the Borrower, and thereafter the Borrower shall pay to such Lender or the Agent, as the case may be, within ten (10) Business Days of written demand therefor from such Lender or the Agent, additional amounts sufficient to compensate such Lender or the Agent (or such controlling corporation) for any increase in the amount of capital and reduced rate of return which such Lender or the Agent reasonably determines to be allocable to the existence of such Lender’s or the Agent’s obligations or Advances hereunder. A statement setting forth the amount of such compensation, the methodology for the calculation and the calculation thereof which shall also be prepared in good faith and in reasonable detail by such Lender or the Agent, as the case may be, shall be submitted by such Lender or by the Agent to the Borrower, reasonably promptly after becoming aware of any event described in this Section 10.5 and shall be conclusively presumed to be correct, absent manifest error. No amounts shall be due under this Section 10.5 to the extent such amounts are due and payable under Section 10.4.

(2) Failure or delay on the part of the Lender to demand compensation pursuant to Sections 10.4 or 10.5 shall not constitute a waiver of such Lender’s right to demand such compensation, except that the Credit Parties shall not be required to compensate the Lenders pursuant to Sections 10.4 or 10.5 for any increased costs incurred or reductions suffered more than 180 days prior to the making of a Lender’s initial request for such additional amounts, unless the event giving rise to such increased costs or reductions is retroactive, in which case the 180 day period referred to above shall be extended to include the period of retroactive effect thereof.

Section 10.6 Right of Lenders to Fund through Branches and Affiliates

Each Lender (including without limitation the Swing Line Lender) may, if it so elects, fulfill its commitment as to any Advance hereunder by designating a branch or Affiliate of such Lender to make such Advance; provided that (a) such Lender shall remain solely responsible for the performances of its obligations hereunder and (b) no such designation shall result in any material increased costs to the Borrower.

Section 10.7 Margin Adjustment

Adjustments to the Applicable Margins and the Applicable Fee Percentages, based on Schedule 1.1(11), shall be implemented on a quarterly basis as follows:

(1) Such adjustments shall be given prospective effect only, effective as to all Advances outstanding hereunder, the Applicable Fee Percentage and the Letter of Credit Fee, upon the date of delivery of the financial statements under Sections 7.1(a) and 7.1(b) hereunder and the Covenant Compliance Report under Section 7.2(a) hereof, in each case establishing applicability of the appropriate adjustment and in each case with no retroactivity or claw-back. In the event the Borrower shall fail timely to deliver such financial statements or the Covenant Compliance Report and such failure continues for three (3) Business Days, then (but without affecting any Event of Default resulting therefrom) from the date delivery of such financial statements and

report was required until such financial statements and report are delivered, the Applicable Margins and Applicable Fee Percentages shall be at the highest level on the Pricing Matrix attached to this Agreement as Schedule 1.1(11).

(2) Notwithstanding the foregoing, however, if, prior to the payment and discharge in full (in cash) of the Indebtedness (other than indemnification obligations for which no claim has been asserted) and the termination of any and all commitments hereunder, as a result of any restatement of or adjustment to the financial statements of the Borrower and any of its Subsidiaries (relating to the current or any prior fiscal period) or for any other reason, the Agent determines that the Applicable Margin and/or the Applicable Fee Percentages as calculated by the Borrower as of any applicable date of determination were inaccurate in any respect and a proper calculation thereof would have resulted in different pricing for any fiscal period, then (x) if the proper calculation thereof would have resulted in higher pricing for any such period, the Borrower shall automatically and retroactively be obligated to pay to the Agent, promptly upon demand by the Agent or the Majority Lenders, an amount equal to the excess of the amount of interest and fees that should have been paid for such period over the amount of interest and fees actually paid for such period and, if the current fiscal period is affected thereby, the Applicable Margin and/or the Applicable Fee Percentages for the current period shall be adjusted based on such recalculation; and (y) if the proper calculation thereof would have resulted in lower pricing for such period, the Agent and Lenders shall have no obligation to recalculate such interest or fees or to repay any interest or fees to the Borrower.

Section 10.8 Illegality

If any Lender determines that any applicable law has made it unlawful, or that any Governmental Authority has asserted that it is unlawful, for any Lender or its applicable lending office to make or maintain any Advance (or to maintain its obligation to make any Advance), to the Borrower or to receive the benefit of a Guarantee from a Guarantor, or receive the benefit of security over the assets or shares of such Borrower or Guarantor, or do business with such Borrower or Guarantor, then, on notice thereof by such Lender to the Borrower through the Agent, any obligation of such Lender with respect to the activity that is unlawful shall be suspended until such Lender notifies the Agent and the Borrower that the circumstances giving rise to such determination no longer exist. Upon receipt of such notice, the Borrower shall, upon demand from such Lender (with a copy to the Agent), either, at the direction of the Lender, (i) agree that the Borrower or such Guarantor shall not become the Borrower or such Guarantor with respect to the Lender and /or agree that the Lender shall not make or maintain any Advance (or maintain its obligation to make any Advance) to the Borrower or receive the benefit of a Guarantee from a Guarantor, or receive the benefit of security over the assets or shares of such Borrower or Guarantor, or do business with such Borrower or Guarantor or (ii) prepay (without prepayment penalty) or, if conversion would avoid the activity that is unlawful, convert any Advances in order to avoid the activity that is unlawful. Upon any such prepayment or conversion, the Borrower shall also pay accrued interest on the amount so prepaid or converted. Each Lender agrees to designate a different lending office if such designation will avoid the need for such notice and will not, in the good faith judgment of such Lender, otherwise be materially disadvantageous to such Lender.

ARTICLE 11 — AGENT

Section 11.1 Appointment of the Agent

Each Lender and the holder of each Note (if issued) irrevocably appoints and authorizes the Agent to act on behalf of such Lender or holder under this Agreement and the other Loan Documents and to exercise such powers hereunder and thereunder as are specifically delegated to the Agent by the terms hereof and thereof, together with such powers as may be reasonably incidental thereto, including without limitation the power to execute or authorize the execution of financing or similar statements or notices, and other documents. In performing its functions and duties under this Agreement, the Agent shall act solely as agent of the Lenders and does not assume and shall not be deemed to have assumed any obligation towards or relationship of agency or trust with or for any Credit Party.

Section 11.2 Deposit Account with the Agent or any Lender

The Borrower authorizes the Agent and each Lender, in the Agent’s or such Lender’s sole discretion, upon notice to the Borrower to charge its general deposit account(s), if any, maintained with the Agent or such Lender for the amount of any principal, interest, or other amounts or costs due under this Agreement when the same become due and payable under the terms of this Agreement or the Notes.

Section 11.3 Scope of the Agent’s Duties

The Agent shall have no duties or responsibilities except those expressly set forth herein, and shall not, by reason of this Agreement or otherwise, have a fiduciary relationship with any Lender (and no implied covenants or other obligations shall be read into this Agreement against the Agent). None of the Agent, its Affiliates nor any of their respective directors, officers, employees or agents shall be liable to any Lender for any action taken or omitted to be taken by it or them under this Agreement or any document executed pursuant hereto, or in connection herewith or therewith with the consent or at the request of the Majority Lenders (or all of the Lenders for those acts requiring consent of all of the Lenders) (except for its or their own willful misconduct or gross negligence), nor be responsible for or have any duties to ascertain, inquire into or verify (a) any recitals or warranties made by the Credit Parties or any Affiliate of the Credit Parties, or any officer thereof contained herein or therein, (b) the effectiveness, enforceability, validity or due execution of this Agreement or any document executed pursuant hereto or any security thereunder, (c) the performance by the Credit Parties of their respective obligations hereunder or thereunder, or (d) the satisfaction of any condition hereunder or thereunder, including without limitation in connection with the making of any Advance or the issuance of any Letter of Credit. The Agent and its Affiliates shall be entitled to rely upon any certificate, notice, document or other communication (including any cable, telegraph, telex, facsimile transmission or oral communication) believed by it to be genuine and correct and to have been sent or given by or on behalf of a proper person. The Agent may treat the payee of any Note as the holder thereof. The Agent may employ agents and may consult with legal counsel, independent public accountants and other experts selected by it and shall not be liable to the Lenders (except as to money or property received by them or their authorized agents), for the negligence or misconduct of any such agent selected by it with reasonable care or for any action taken or omitted to be taken by it in good faith in accordance with the advice of such counsel, accountants or experts.

Section 11.4 Successor Agent

The Agent may resign as such at any time upon at least thirty (30) days prior notice to the Borrower and each of the Lenders. If the Agent at any time shall resign or if the office of the Agent shall become vacant for any other reason, Majority Lenders shall, by written instrument, appoint successor agent(s) (“Successor Agent”) satisfactory to such Majority Lenders and, so long as no Default or Event of Default has occurred and is continuing, to the Borrower (which approval shall not be unreasonably withheld or delayed); provided, however that any such successor Agent shall be a bank or a trust company or other financial institution which maintains an office in the United States or Canada, or a commercial bank organized under the laws of the United States, Canada or any state or province thereof, or any Affiliate of such bank or trust company or other financial institution which is engaged in the banking business, and shall have a combined capital and surplus of at least $500,000,000. Such Successor Agent shall thereupon become the Agent hereunder, as applicable, and the Agent shall deliver or cause to be delivered to any successor agent such documents of transfer and assignment as such Successor Agent may reasonably request. If a Successor Agent is not so appointed or does not accept such appointment before the resigning Agent’s resignation becomes effective, the resigning Agent may appoint a temporary successor to act until such appointment by the Majority Lenders and, if applicable, the Borrower, is made and accepted, or if no such temporary successor is appointed as provided above by the resigning Agent, the Majority Lenders shall thereafter perform all of the duties of the resigning Agent hereunder until such appointment by the Majority Lenders and, if applicable, the Borrower, is made and accepted. Such Successor Agent shall succeed to all of the rights and obligations of the resigning Agent as if originally named. The resigning Agent shall duly assign, transfer and deliver to such Successor Agent all moneys at the time held by the resigning Agent hereunder after deducting therefrom its expenses for which it is entitled to be reimbursed hereunder. Upon such succession of any such Successor Agent, the resigning Agent shall be discharged from its duties and obligations, in its capacity as the Agent hereunder, except for its gross negligence or willful misconduct arising prior to its resignation hereunder, and the provisions of this Article 11 shall continue in effect for the benefit of the resigning Agent in respect of any actions taken or omitted to be taken by it while it was acting as the Agent.

Section 11.5 Credit Decisions

Each Lender acknowledges that it has, independently of the Agent and each other Lender and based on the financial statements of the Borrower and such other documents, information and investigations as it has deemed appropriate, made its own credit decision to extend credit hereunder from time to time. Each Lender also acknowledges that it will, independently of the Agent and each other Lender and based on such other documents, information and investigations as it shall deem appropriate at any time, continue to make its own credit decisions as to exercising or not exercising from time to time any rights and privileges available to it under this Agreement, any Loan Document or any other document executed pursuant hereto.

Section 11.6 Authority of the Agent to Enforce This Agreement

Each Lender, subject to the terms and conditions of this Agreement, grants the Agent full power and authority as attorney-in-fact to institute and maintain actions, suits or proceedings for the collection and enforcement of any Indebtedness outstanding under this Agreement or any other Loan Document and to file such proofs of debt or other documents as may be necessary to

100

have the claims of the Lenders allowed in any proceeding relative to any Credit Party, or their respective creditors or affecting their respective properties, and to take such other actions which the Agent considers to be necessary or desirable for the protection, collection and enforcement of the Notes, this Agreement or the other Loan Documents.

Section 11.7 Indemnification of the Agent

The Lenders agree (which agreement shall survive the expiration or termination of this Agreement) to indemnify the Agent and its Affiliates (to the extent not reimbursed by the Borrower, but without limiting any obligation of the Borrower to make such reimbursement), ratably according to their respective Weighted Percentages, from and against any and all claims, damages, losses, liabilities, costs or expenses of any kind or nature whatsoever (including, without limitation, reasonable fees and expenses of house and outside counsel) which may be imposed on, incurred by, or asserted against the Agent and its Affiliates in any way relating to or arising out of this Agreement, any of the other Loan Documents or the transactions contemplated hereby or any action taken or omitted by the Agent and its Affiliates under this Agreement or any of the Loan Documents; provided, however, that no Lender shall be liable for any portion of such claims, damages, losses, liabilities, costs or expenses resulting from the Agent’s or its Affiliate’s gross negligence or willful misconduct. Without limitation of the foregoing, each Lender agrees to reimburse the Agent and its Affiliates promptly upon demand for its ratable share of any reasonable out-of-pocket expenses (including, without limitation, reasonable fees and expenses of house and outside counsel) incurred by the Agent and its Affiliates in connection with the preparation, execution, delivery, administration, modification, amendment or enforcement (whether through negotiations, legal proceedings or otherwise) of, or legal advice in respect of rights or responsibilities under, this Agreement or any of the other Loan Documents, to the extent that the Agent and its Affiliates are not reimbursed for such expenses by the Borrower, but without limiting the obligation of the Borrower to make such reimbursement. Each Lender agrees to reimburse the Agent and its Affiliates promptly upon demand for its ratable share of any amounts owing to the Agent and its Affiliates by the Lenders pursuant to this Section, provided that, if the Agent or its Affiliates are subsequently reimbursed by the Borrower for such amounts, they shall refund to the Lenders on a pro rata basis the amount of any excess reimbursement. If the indemnity furnished to the Agent and its Affiliates under this Section shall become impaired as determined in the Agent’s reasonable judgment or the Agent shall elect in its sole discretion to have such indemnity confirmed by the Lenders (as to specific matters or otherwise), the Agent shall give notice thereof to each Lender and, until such additional indemnity is provided or such existing indemnity is confirmed, the Agent may cease, or not commence, to take any action. Any amounts paid by the Lenders hereunder to the Agent or its Affiliates shall be deemed to constitute part of the Indebtedness hereunder.

Section 11.8 Knowledge of Default

It is expressly understood and agreed that the Agent shall be entitled to assume that no Default or Event of Default has occurred and is continuing, unless the officers of the Agent immediately responsible for matters concerning this Agreement shall have received a written notice from a Lender or the Borrower specifying such Default or Event of Default and stating that such notice is a “notice of default”. Upon receiving such a notice, the Agent shall promptly notify each Lender of such Default or Event of Default and provide each Lender with a copy of such notice and shall endeavor to provide such notice to the Lenders within three (3) Business

101

Days (but without any liability whatsoever in the event of its failure to do so). The Agent shall also furnish the Lenders, promptly upon receipt, with copies of all other notices or other information required to be provided by the Borrower hereunder.

Section 11.9 The Agent’s Authorization; Action by Lenders

Except as otherwise expressly provided herein, whenever the Agent is authorized and empowered hereunder on behalf of the Lenders to give any approval or consent, or to make any request, or to take any other action on behalf of the Lenders (including without limitation the exercise of any right or remedy hereunder or under the other Loan Documents), the Agent shall be required to give such approval or consent, or to make such request or to take such other action only when so requested in writing by the Majority Lenders or the Lenders, as applicable hereunder. Action that may be taken by the Majority Lenders, any other specified Percentage of the Lenders or all of the Lenders, as the case may be (as provided for hereunder) may be taken (i) pursuant to a vote of the requisite percentages of the Lenders as required hereunder at a meeting (which may be held by telephone conference call), provided that the Agent exercises good faith, diligent efforts to give all of the Lenders reasonable advance notice of the meeting, or (ii) pursuant to the written consent of the requisite percentages of the Lenders as required hereunder, provided that all of the Lenders are given reasonable advance notice of the requests for such consent.

Section 11.10 Enforcement Actions by the Agent

Except as otherwise expressly provided under this Agreement or in any of the other Loan Documents and subject to the terms hereof, the Agent will take such action, assert such rights and pursue such remedies under this Agreement and the other Loan Documents as the Majority Lenders or all of the Lenders, as the case may be (as provided for hereunder), shall direct; provided, however, that the Agent shall not be required to act or omit to act if, in the reasonable judgment of the Agent, such action or omission may expose the Agent to personal liability for which the Agent has not been satisfactorily indemnified hereunder or is contrary to this Agreement, any of the Loan Documents or applicable law. Except as expressly provided above or elsewhere in this Agreement or the other Loan Documents, no Lender (other than the Agent, acting in its capacity as agent) shall be entitled to take any enforcement action of any kind under this Agreement or any of the other Loan Documents.

Section 11.11 Collateral Matters.

(1) The Agent is authorized on behalf of all the Lenders, without the necessity of any notice to or further consent from the Lenders, from time to time to take any action with respect to any Collateral or the Collateral Documents which may be necessary to perfect and maintain a perfected security interest in and Liens upon the Collateral granted pursuant to the Loan Documents.

(2) The Lenders irrevocably authorize the Agent, in its reasonable discretion, to the full extent set forth in Section 12.10(4) hereof, (1) to release or terminate any Lien granted to or held by the Agent upon any Collateral (a) upon termination of the Revolving Credit Aggregate Commitment and payment in full of all Indebtedness (other than indemnification obligations for which no claim has been asserted) payable under this Agreement and under any other Loan Document; (b) constituting property (including, without limitation, Equity Interests in any

102

Person) sold or to be sold or disposed of as part of or in connection with any disposition (whether by sale, by merger or by any other form of transaction and including the property of any Subsidiary that is disposed of as permitted hereby) permitted in accordance with the terms of this Agreement; (c) constituting property in which a Credit Party owned no interest at the time the Lien was granted or at any time thereafter; or (d) if approved, authorized or ratified in writing by the Majority Lenders, or all the Lenders, as the case may be, as provided in Section 12.10; (2) to subordinate the Lien granted to or held by the Agent on any Collateral to any other holder of a Lien on such Collateral which is permitted by Section 7.2(2) hereof; and (3) if all of the Equity Interests held by the Credit Parties in any Person are sold or otherwise transferred to any transferee other than the Borrower or a Subsidiary of the Borrower as part of or in connection with any disposition (whether by sale, by merger or by any other form of transaction) permitted in accordance with the terms of this Agreement, to release such Person from all of its obligations under the Loan Documents (including, without limitation, under any Guarantee). Upon request by the Agent at any time, the Lenders will confirm in writing the Agent’s authority to release particular types or items of Collateral pursuant to this Section 11.11(2).

Section 11.12 The Agents in their Individual Capacities

Comerica Bank and its Affiliates, successors and assigns shall each have the same rights and powers hereunder as any other Lender and may exercise or refrain from exercising the same as though such Lender were not the Agent. Comerica Bank and its Affiliates may (without having to account therefor to any Lender) accept deposits from, lend money to, and generally engage in any kind of banking, trust, financial advisory or other business with the Credit Parties as if such Lender were not acting as the Agent hereunder, and may accept fees and other consideration therefor without having to account for the same to the Lenders.

Section 11.13 The Agent’s Fees

Until the Indebtedness (other than indemnification obligations for which no claim has been asserted) has been repaid and discharged in full and no commitment to extend any credit hereunder is outstanding, the Borrower shall pay to the Agent, as applicable, any agency or other fee(s) set forth (or to be set forth from time to time) in the Fee Letter on the terms set forth therein. The agency fees referred to in this Section 11.13 shall not be refundable under any circumstances.

Section 11.14 Documentation Agent or other Titles

Any Lender identified on the facing page or signature page of this Agreement or in any amendment hereto or as designated with consent of the Agent in any assignment agreement as Lead Arranger, Documentation Agent, Syndications Agent or any similar titles, shall not have any right, power, obligation, liability, responsibility or duty under this Agreement as a result of such title other than those applicable to all Lenders as such. Without limiting the foregoing, the Lenders so identified shall not have or be deemed to have any fiduciary relationship with any Lender as a result of such title.

Section 11.15 Patriot Act, AML Laws, and Customer Identification Program

(1) Each Lender acknowledges and agrees that neither such Lender, nor any of its Affiliates, participants or assignees, may rely on the Agent to carry out such Lender’s, Affiliate’s, participant’s or assignee’s customer identification program, or other obligations required or imposed under or pursuant to the USA Patriot Act or the regulations thereunder, including the regulations contained in 31 CFR 103.121 (as hereafter amended or replaced, the “CIP Regulations”), or any other AML Laws, including any programs involving any of the following items relating to or in connection with the Borrower or any of its Subsidiaries, any of their respective Affiliates or agents, the Loan Documents or the transactions hereunder: (i) any identify verification procedures, (ii) any record keeping, (iii) any comparisons with government lists, (iv) any customer notices or (v) any other procedures required under the CIP Regulations or such other laws.

(2) Each Lender or assignee or participant of a Lender that is not organized under the laws of the United States or a state thereof (and is not excepted from the certification requirement contained in Section 313 of the USA Patriot Act and the applicable regulations because it is both (i) an affiliate of a depository institution or foreign bank that maintains a physical presence in the United States or foreign country, and (ii) subject to supervision by a banking authority regulating such affiliated depository institution or foreign bank) shall, upon request by the Agent, deliver to the Agent the certification, or, if applicable, recertification, certifying that such Lender is not a “shell” and certifying to other matters as required by Section 313 of the USA Patriot Act and the applicable regulations in such form as is no less than the Agent reasonably believes is necessary for compliance therewith: (x) within 10 days after the Effective Date, and (y) upon request by the Agent, at such other times as are required under the USA Patriot Act.

(3) If the Agent has ascertained the identity of the Borrower or any authorized signatories of the Borrower for the purposes of applicable AML Laws, then the Agent (i) shall be deemed to have done so as an agent for each Lender, and this Agreement shall constitute a “written agreement” in such regard between each Lender and the Agent within the meaning of the applicable AML Laws; and (ii) shall provide to each Lender copies of all information obtained in such regard without any representation or warranty as to its accuracy or completeness. Notwithstanding the preceding sentence and except as may otherwise be agreed in writing, each Lender agrees that the Agent has no obligation to ascertain the identity of the Borrower or any authorized signatories of the Borrower on behalf of any Lender, or to confirm the completeness or accuracy of any information it obtains from the Borrower or any such authorized signatory in doing so.

ARTICLE 12 — MISCELLANEOUS.

This Agreement, the Notes and, except where otherwise expressly specified therein to be governed by local law, the other Loan Documents shall be governed by and construed and enforced in accordance with the laws of the Province of Ontario and the federal laws of Canada applicable therein (without regard to its conflict of laws provisions). Whenever possible each provision of this Agreement shall be interpreted in such manner as to be effective and valid under applicable law, but if any provision of this Agreement shall be prohibited by or invalid under applicable law, such provision shall be ineffective to the extent of such prohibition or invalidity, without invalidating the remainder of such provision or the remaining provisions of this Agreement.

All of said amounts required to be paid by the Borrower hereunder and not paid forthwith upon demand, as aforesaid, shall bear interest, from the date incurred to the date payment is received by the Agent, at the US Base Rate, plus three percent (3%).

(2) The Borrower agrees to indemnify and hold the Agent and each of the Lenders (and their respective Affiliates and their respective employees, agents, officers and directors) harmless from all loss, cost, damage, liability or expenses, including reasonable in-house and outside attorneys’ fees and disbursements (but without duplication of such fees and disbursements for the same services), incurred by the Agent and each of the Lenders by reason of an Event of Default, or enforcing the obligations of any Credit Party under this Agreement or any of the other Loan Documents, as applicable, or in the prosecution or defense of any action or proceeding concerning any matter growing out of or connected with this Agreement or any of the Loan Documents, excluding, however, any loss, cost, damage, liability or expenses to the extent arising as a result of the gross negligence or wilful misconduct of the party seeking to be indemnified under this Section 12.5(2).

The Borrower, from time to time, upon written request of the Agent will make, execute, acknowledge and deliver or cause to be made, executed, acknowledged and delivered, all such further and additional instruments, and take all such further action as may reasonably be required to carry out the intent and purpose of this Agreement or the Loan Documents, and to provide for Advances under and payment of the Notes, according to the intent and purpose herein and therein expressed.

Section 12.8 Successors and Assigns; Participations; Assignments.

(1) This Agreement shall be binding upon and shall inure to the benefit of the Borrower and the Lenders and their respective successors and assigns.

(2) The foregoing shall not authorize any assignment by the Borrower of its rights or duties hereunder, and, except as otherwise provided herein, no such assignment shall be made (or be effective) without the prior written approval of the Lenders.

(3) No Lenders may at any time assign or grant participations in such Lender’s rights and obligations hereunder and under the other Loan Documents except (i) by way of assignment to any Eligible Assignee in accordance with clause (4) of this Section, (ii) by way of a participation in accordance with the provisions of clause (5) of this Section or (iii) by way of a pledge or assignment of a security interest subject to the restrictions of clause (6) of this Section (and any other attempted assignment or transfer by any Lender shall be deemed to be null and void).

(4) Each assignment by a Lender of all or any portion of its rights and obligations hereunder and under the other Loan Documents, shall be subject to the following terms and conditions:

(a) each such assignment shall be made on a pro rata basis and shall be in a minimum amount of the lesser of (x) Five Million Dollars (US$5,000,000) or such lesser amount as the Agent and the Borrower (unless there is an Event of Default that has occurred and is continuing, in which case the Agent alone may determine such assignment), shall agree and (y) the entire remaining amount of assigning Lender’s aggregate interest in the Revolving Credit (and participations in any outstanding Letters of Credit); provided however that, after giving effect to such assignment, in no event shall the entire remaining amount (if any) of assigning Lender’s aggregate interest in the Revolving Credit (and participations in any outstanding Letters of Credit) be less than US$5,000,000; and

(b) the parties to any assignment shall execute and deliver to the Agent an Assignment Agreement substantially (as determined by the Agent) in the form attached hereto as Exhibit H (with appropriate insertions acceptable to the Agent), together with a processing and recordation fee in the amount, if any, required as set forth in the Assignment Agreement.

Until the Assignment Agreement becomes effective in accordance with its terms, and the Agent has confirmed that the assignment satisfies the requirements of this Section 12.8, the Borrower and the Agent shall be entitled to continue to deal solely and directly with the assigning Lender in connection with the interest so assigned. From and after the effective date of each Assignment

108

Agreement that satisfies the requirements of this Section 12.8, the assignee thereunder shall be deemed to be a party to this Agreement, such assignee shall have the rights and obligations of a Lender under this Agreement and the other Loan Documents (including without limitation the right to receive fees payable hereunder in respect of the period following such assignment) and the assigning Lender shall relinquish its rights and be released from its obligations under this Agreement and the other Loan Documents.

Upon request, the Borrower shall execute and deliver to the Agent, new Note(s) payable to the order of the assignee in an amount equal to the amount assigned to the assigning Lender pursuant to such Assignment Agreement, and with respect to the portion of the Indebtedness retained by the assigning Lender, to the extent applicable, new Note(s) payable to the order of the assigning Lender in an amount equal to the amount retained by such Lender hereunder. The Agent, the Lenders and the Borrower acknowledges and agrees that any such new Note(s) shall be given in renewal and replacement of the Notes issued to the assigning lender prior to such assignment and shall not effect or constitute a novation or discharge of the Indebtedness evidenced by such prior Note, and each such new Note may contain a provision confirming such agreement.

(5) The Borrower and the Agent acknowledge that each of the Lenders may at any time and from time to time, subject to the terms and conditions hereof, grant participations in such Lender’s rights and obligations hereunder (on a pro rata basis only) and under the other Loan Documents to any Person (other than a natural person or to the Borrower or any of the Borrower’s Affiliates or Subsidiaries); provided that any participation permitted hereunder shall comply with all applicable laws and shall be subject to a participation agreement that incorporates the following restrictions:

(a) such Lender shall remain the holder of its Notes hereunder (if such Notes are issued), notwithstanding any such participation;

(b) a participant shall not reassign or transfer, or grant any sub-participations in its participation interest hereunder or any part thereof;

(c) such Lender shall retain the sole right and responsibility to enforce the obligations of the Credit Parties relating to the Notes and the other Loan Documents, including, without limitation, the right to proceed against any Guarantors, or cause the Agent to do so (subject to the terms and conditions hereof), and the right to approve any amendment, modification or waiver of any provision of this Agreement without the consent of the participant (unless such participant is an Affiliate of such Lender), except for those matters requiring the consent of each of the Lenders under Section 12.10(2) (provided that a participant may exercise approval rights over such matters only on an indirect basis, acting through such Lender and the Credit Parties, the Agent and the other Lenders may continue to deal directly with such Lender in connection with such Lender’s rights and duties hereunder). Notwithstanding the foregoing, however, in the case of any participation granted by any Lender hereunder, the participant shall not have any rights under this Agreement or any of the other Loan Documents against the Agent, any other Lender or any Credit Party; provided, however that the participant may have rights against such Lender in respect of such participation as may be set forth in the applicable participation agreement and all amounts payable

109

by the Credit Parties hereunder shall be determined as if such Lender had not so ld such participation. Each such participant shall be entitled to the benefits of Article 10 of this Agreement to the same extent as if it were a Lender and had acquired its interest by assignment pursuant to clause (d) of this Section, provided that no participant shall be entitled to receive any greater amount pursuant to such the provisions of Article 10 than the issuing Lender would have been entitled to receive in respect of the amount of the participation transferred by such issuing Lender to such participant had no such transfer occurred and each such participant shall also be entitled to the benefits of Section 8.6 hereof as though it were a Lender, provided that such participant agrees to be subject to Section 9.3 hereof as though it were a Lender; and

(d) each participant shall provide the relevant tax form required under Section 12.11.

(6) Any Lender may at any time pledge or assign a security interest in all or any portion of its rights under this Agreement (including its Notes, if any) to secure obligations of such Lender, including any pledge or assignment to secure obligations to a Federal Reserve Bank; provided that no such pledge or assignment shall release such Lender from any of its obligations hereunder or substitute any such pledge or assignee for such Lender as a party hereto.

(7) The Agent shall maintain at its principal office a copy of each Assignment Agreement delivered to it and a register (the “Register”) for the recordation of the names and addresses of the Lenders, the Percentages of such Lenders and the principal amount of each type of Advance owing to each such Lender from time to time. The entries in the Register shall be conclusive evidence, absent manifest error, and the Borrower, the Agent, and the Lenders may treat each Person whose name is recorded in the Register as the owner of the Advances recorded therein for all purposes of this Agreement. The Register shall be available for inspection by the Borrower or any Lender (but only with respect to any entry relating to such Lender’s Percentages and the principal amounts owing to such Lender) upon reasonable notice to the Agent and a copy of such information shall be provided to any such party on their prior written request. The Agent shall give prompt written notice to the Borrower of the making of any entry in the Register or any change in such entry.

(8) The Borrower authorizes each Lender to disclose to any prospective assignee or participant which has satisfied the requirements hereunder, any and all financial information in such Lender’s possession concerning the Credit Parties which has been delivered to such Lender pursuant to this Agreement, provided that each such prospective assignee or participant shall execute a confidentiality agreement consistent with the terms of Section 12.11 hereof or shall otherwise agree to be bound by the terms thereof.

(9) Nothing in this Agreement, the Notes or the other Loan Documents, expressed or implied, is intended to or shall confer on any Person other than the respective parties hereto and thereto and their successors and assignees and participants permitted hereunder and thereunder any benefit or any legal or equitable right, remedy or other claim under this Agreement, the Notes or the other Loan Documents.

(iv) any modifications to the definitions of “Collateral Coverage Amount”, “Eligible Accounts” and “Eligible Insured Accounts”;

111

(i) except as expressly permitted hereunder or under the Collateral Documents, release all or substantially all of the Collateral (provided that neither the Agent nor any Lender shall be prohibited thereby from proposing or participating in a consensual or non-consensual debtor-in- possession or similar financing), or release any material guarantee provided by any Person in favour of the Agent and the Lenders, provided however that the Agent shall be entitled, without notice to or any further action or consent of the Lenders, to release any Collateral which any Credit Party is permitted to sell, assign or otherwise transfer in compliance with this Agreement or the other Loan Documents or release any guarantee to the extent expressly permitted in this Agreement or any of the other Loan Documents (whether in connection with the sale, transfer or other disposition of the applicable Guarantor or otherwise),

(ii) increase the maximum duration of Interest Periods permitted hereunder; or

(iii) modify Sections 9.2 or 9.3 hereof;

(3) Notwithstanding anything to the contrary herein, no Defaulting Lender shall have any right to approve or disapprove of any amendment, consent, waiver or any other modification to any Loan Document (and all amendments, consents, waivers and other modifications may be effected without the consent of the Defaulting Lenders), except that the foregoing shall not permit, in each case without such Defaulting Lender’s consent, (i) an increase in such Defaulting Lender’s stated commitment amounts, (ii) the waiver, forgiveness or reduction of the principal amount of any Indebtedness owing to such Defaulting Lender (unless all other Lenders affected thereby are treated similarly), (iii) the extension of the final maturity date(s) of such Defaulting Lenders’ portion of any of the Indebtedness or the extension of any commitment to extend credit of such Defaulting Lender, or (iv) any other modification which requires the consent of all Lenders or the Lender(s) affected thereby which affects such Defaulting Lender more adversely than the other affected Lenders (other than a modification which results in a reduction of such Defaulting Lender’s Percentage of any Commitments or repayment of any amounts owing to such Defaulting Lender on a non pro-rata basis).

112

(4) The Agent shall, upon the written request of the Borrower, execute and deliver to the Credit Parties such documents as may be necessary to evidence (1) the release of any Lien granted to or held by the Agent upon any Collateral: (a) upon termination of the Revolving Credit Aggregate Commitment and payment in full of all Indebtedness (other than in respect of contingent indemnification obligations for which no claim has been asserted) payable under this Agreement and under any other Loan Document; (b) which constitutes property (including, without limitation, Equity Interests in any Person) sold or to be sold or disposed of as part of or in connection with any disposition (whether by sale, by merger or by any other form of transaction and including the property of any Subsidiary that is disposed of as permitted hereby) permitted in accordance with the terms of this Agreement; (c) which constitutes property in which a Credit Party owned no interest at the time the Lien was granted or at any time thereafter; or (d) if approved, authorized or ratified in writing by the Majority Lenders, or all the Lenders, as the case may be, as provided in this Section 12.10; or (2) the release of any Person from its obligations under the Loan Documents (including without limitation the Guarantee) if all of the Equity Interests of such Person that were held by a Credit Party are sold or otherwise transferred to any transferee other than the Borrower or a Subsidiary of the Borrower as part of or in connection with any disposition (whether by sale, by merger or by any other form of transaction) permitted in accordance with the terms of this Agreement; provided that (i) the Agent shall not be required to execute any such release or subordination agreement under clauses (1) or (2) above on terms which, in the Agent’s opinion, would expose the Agent to liability or create any obligation or entail any consequence other than the release of such Liens without recourse or warranty or such release shall not in any manner discharge, affect or impair the Indebtedness or any Liens upon any Collateral retained by any Credit Party, including (without limitation) the proceeds of the sale or other disposition, all of which shall constitute and remain part of the Collateral.

(5) Notwithstanding anything to the contrary herein the Agent may, with the consent of the Borrower only, amend, modify or supplement this Agreement or any of the other Loan Documents to cure any ambiguity, omission, mistake, defect or inconsistency

Section 12.11 Confidentiality

113

(2) Each Lender acknowledges that the Borrower: (i) is permitted to reference this Agreement including any Schedules or Exhibits hereto (and any amendments hereto or thereto) in any and all public and private filings with applicable securities regulators and (ii) is permitted to publicly file a copy of this Agreement including any Schedules or Exhibits hereto (and any amendments hereto or thereto) with applicable securities regulators (subject to such redactions permitted by securities regulators as may reasonably be requested by the Lenders).

Section 12.12 Substitution or Removal of Lenders

(1) With respect to any Lender (i) whose obligation to make Eurodollar-based Advances or CDOR-based Advances has been suspended pursuant to Section 10.2 or Section 10.3, (ii) that has demanded compensation under Sections 3.5, 10.4 or 10.5, (iii) that has become a Defaulting Lender or (iv) that has failed to consent to a requested amendment, waiver or modification to any Loan Document as to which the Majority Lenders have already consented (in each case, an “Affected Lender”), then the Agent or the Borrower may, at the Borrower’s sole expense, require the Affected Lender to sell and assign all of its interests, rights and obligations under this Agreement, including, without limitation, its Commitments, to an assignee (which may be one or more of the Lenders) (such assignee shall be referred to herein as the “Purchasing Lender” or “Purchasing Lenders”) within two (2) Business Days after receiving notice from the Borrower requiring it to do so, for an aggregate price equal to the sum of the portion of all Advances made by it, interest and fees accrued for its account through but excluding the date of such payment, and all other amounts payable to it hereunder, from the Purchasing Lender(s) (to the extent of such outstanding principal and accrued interest and fees) or the Borrower (in the case of all other amounts, including without limitation, if demanded by the Affected Lender, the amount of any compensation that due to the Affected Lender under Sections 3.5, 10.1, 10.4 or 10.5 to but excluding said date), payable (in immediately available funds) in cash. The Affected Lender, as assignor, such Purchasing Lender, as assignee, the Borrower and the Agent, shall enter into an Assignment Agreement pursuant to Section 12.8 hereof, whereupon such Purchasing Lender shall be a Lender party to this Agreement, shall be deemed to be an assignee hereunder and shall have all the rights and obligations of a Lender with a Revolving Credit Percentage equal to its ratable share of the then applicable Revolving Credit Aggregate Commitment of the Affected Lender, provided, however, that if the Affected Lender does not execute such Assignment Agreement within (2) Business Days of receipt thereof, the Agent may execute the Assignment Agreement as the Affected Lender’s attorney-in-fact. Each of the Lenders hereby irrevocably constitutes and appoints the Agent and any officer or agent thereof, with full power of substitution, as its true and lawful attorney-in-fact with full power and authority in the name of such Lender or in its own name to execute and deliver the Assignment Agreement while such Lender is an Affected Lender hereunder (such power of attorney to be deemed coupled with an interest and irrevocable). In connection with any assignment pursuant to this Section 12.12, the Borrower or the Purchasing Lender shall pay to the Agent the administrative fee for processing such assignment referred to in Section 13.8.

(2) If any Lender is an Affected Lender of the type described in Section 12.10(2)(c) and (d) (any such Lender, a “Non-Compliant Lender”), the Borrower may, with the prior written consent of the Agent, and notwithstanding Section 9.3 of this Agreement or any other provisions requiring pro rata payments to the Lenders, elect to reduce any Commitments by an amount equal to the Non-Compliant Lender’s Percentage of the Commitment of such Impaired Lender and repay such Non-Compliant Lender an amount equal the principal amount of all Advances

114

owing to it, all interest and fees accrued for its account through but excluding the date of such repayment, and all other amounts payable to it hereunder (including without limitation, if demanded by the Non-Compliant Lender, the amount of any compensation that due to the Non- Compliant Lender under Sections 3.5, 10.1, 10.4 or 10.5 to but excluding said date), payable (in immediately available funds) in cash, so long as, after giving effect to the termination of Commitments and the repayments described in this clause (b), any Fronting Exposure of such Non-Compliant Lender shall be reallocated among the Lenders that are not Non-Compliant Lenders in accordance with their respective Revolving Credit Percentages, but only to the extent that the sum of the aggregate principal amount of all Revolving Credit Advances made by each such Lender, plus such Lender’s Percentage of the aggregate outstanding principal amount of Swing Line Advances, Letter of Credit Obligations and Hedging Obligations prior to giving effect to such reallocation plus such Lender’s Percentage of the Fronting Exposure to be reallocated does not exceed such Lender’s Percentage of the Revolving Credit Aggregate Commitment, and with respect to any portion of the Fronting Exposure that may not be reallocated, the Borrower shall deliver to the Agent, for the benefit of the Issuing Lender and/or Swing Line Lender, as applicable, cash collateral or other security satisfactory to the Agent, with respect any such remaining Fronting Exposure.

Section 12.13 Withholding Taxes

(1) If any Lender is not a “united states person” within the meaning of Section 7701(a)(30) of the Internal Revenue Code, such Lender shall promptly (but in any event prior to the initial payment of interest hereunder or prior to its accepting any assignment under Section 12.8 hereof, as applicable) deliver to the Agent two original executed copies of (i) Internal Revenue Service Form W-8BEN or any successor form specifying the applicable tax treaty between the United States and the jurisdiction of such Lender’s domicile which provides for the exemption from withholding on interest payments to such Lender, (ii) Internal Revenue Service Form W-8ECI or any successor form evidencing that the income to be received by such Lender hereunder is effectively connected with the conduct of a trade or business in the United States or (iii) other evidence satisfactory to the Agent that such Lender is exempt from United States income tax withholding with respect to such income; provided, however, that such Lender shall not be required to deliver to the Agent the aforesaid forms or other evidence with respect to Advances to the Borrower, if such Lender has assigned its entire interest hereunder (including its Revolving Credit Commitment Amount, any outstanding Advances hereunder and participations in Letters of Credit issued hereunder and any Notes issued to it by the Borrower), to an Affiliate which is incorporated under the laws of the United States or a state thereof, and so notifies the Agent. Such Lender shall amend or supplement any such form or evidence as required to insure that it is accurate, complete and non-misleading at all times. Promptly upon notice from the Agent of any determination by the CRA or the Internal Revenue Service that any payments previously made to such Lender hereunder were subject to United States income tax withholding when made, such Lender shall pay to the Agent the excess of the aggregate amount required to be withheld from such payments over the aggregate amount actually withheld by the Agent. In addition, from time to time upon the reasonable request and the sole expense of the Borrower, each Lender and the Agent shall (to the extent it is able to do so based upon applicable facts and circumstances), complete and provide the Borrower with such forms, certificates or other documents as may be reasonably necessary to allow the Borrower, as applicable, to make any payment under this Agreement or the other Loan Documents without any withholding for or on the account of any tax under Section 9.1(4) hereof (or with such withholding at a reduced rate),

115

provided that the execution and delivery of such forms, certificates or other documents does not adversely affect or otherwise restrict the rights and benefits (including without limitation economic benefits) available to such Lender or the Agent, as the case may be, under this Agreement or any of the other Loan Documents, or under or in connection with any transactions not related to the transactions contemplated hereby.

(2) Any Lender (or assignee or participant permitted under Section 12.8 that is a “united states person” within the meaning of Section 7701(a)(30) of the Internal Revenue Code shall promptly (but in any event prior to the initial payment of interest hereunder or prior to its accepting any assignment under Section 12.8 hereof, as applicable) deliver to the Agent and the Borrower two properly completed and duly executed originals of Internal Revenue Service Form W-9, or any subsequent versions thereof or successors thereto.

Section 12.14 Taxes and Fees

Should any tax (other than as a result of a Lender’s failure to comply with Section 12.13 or a tax based upon the net income or capitalization of any Lender or the Agent by any jurisdiction where a Lender or the Agent is or has been located), or recording or filing fee become payable in respect of this Agreement or any of the other Loan Documents or any amendment, modification or supplement hereof or thereof, the Borrower agrees to pay the same, together with any interest or penalties thereon arising from the Borrower’s actions or omissions, and agrees to hold the Agent and the Lenders harmless with respect thereto provided, however, that the Borrower shall not be responsible for any such interest or penalties which were incurred prior to the date that notice is given to the Credit Parties of such tax or fees. Notwithstanding the foregoing, nothing contained in this Section 12.14 shall affect or reduce the rights of any Lender or the Agent under Section 10.4 hereof. Each Credit Party will, and will cause each of its Subsidiaries to, withhold all employee withholdings and make all employer contributions to be withheld and made by it pursuant to applicable Law on account of the Canada Pension Plan and the Quebec Pension Plans, employment insurance and employee income taxes.

Section 12.15 WAIVER OF JURY TRIAL

THE LENDERS, THE AGENT AND THE BORROWER KNOWINGLY, VOLUNTARILY AND INTENTIONALLY WAIVE ANY RIGHT ANY OF THEM MAY HAVE TO A TRIAL BY JURY IN ANY LITIGATION BASED UPON OR ARISING OUT OF THIS AGREEMENT OR ANY RELATED INSTRUMENT OR AGREEMENT OR ANY OF THE TRANSACTIONS CONTEMPLATED BY THIS AGREEMENT OR ANY COURSE OF CONDUCT, DEALING, STATEMENTS (WHETHER ORAL OR WRITTEN) OR ACTION OF ANY OF THEM. NEITHER THE LENDERS, THE AGENT NOR THE BORROWER SHALL SEEK TO CONSOLIDATE, BY COUNTERCLAIM OR OTHERWISE, ANY SUCH ACTION IN WHICH A JURY TRIAL HAS BEEN WAIVED WITH ANY OTHER ACTION IN WHICH A JURY TRIAL CANNOT BE OR HAS NOT BEEN WAIVED. THESE PROVISIONS SHALL NOT BE DEEMED TO HAVE BEEN MODIFIED IN ANY RESPECT OR RELINQUISHED BY THE LENDERS AND THE AGENT OR THE BORROWER EXCEPT BY A WRITTEN INSTRUMENT EXECUTED BY ALL OF THEM.

116

Section 12.16 Patriot Act and AML Laws Notice

The Agent and the Lenders that are subject to the AML Laws and USA Patriot Act hereby notify the Credit Parties, pursuant to AML Laws and section 326 of the USA Patriot Act, that if they or any of their Subsidiaries open an account, including any loan, deposit account, treasury management account, or other extension of credit with the Agent or any Lender, the Agent or the applicable Lender will request the applicable Person’s name, tax identification number, business address and other information necessary to identify such Person (and may request such Person’s organizational documents or other identifying documents) to the extent necessary for the Agent and the applicable Lender to comply with AML Laws and the USA Patriot Act.

Section 12.21 Independence of Covenants

Each covenant hereunder shall be given independent effect (subject to any exceptions stated in such covenant) so that if a particular action or condition is not permitted by any such covenant (taking into account any such stated exception), the fact that it would be permitted by an exception to, or would be otherwise within the limitations of, another covenant shall not avoid the occurrence of a Default or an Event of Default.

To: Borrower
and

Comerica Bank (“Agent”)

Re: Revolving Credit Agreement made as of the 1st day of June, 2012 (as amended, restated, supplemented or otherwise modified from time to time, the “Credit Agreement”), by and among the financial institutions from time to time signatory thereto (individually a “Lender,” and any and all such financial institutions collectively, “Lenders”), Comerica Bank, as administrative agent for the Lenders (in such capacity, the “Agent”), and DragonWave Inc. as borrower (the “Borrower”).

Ladies and Gentlemen:

Reference is made to Section 12.8 of the Credit Agreement. Unless otherwise defined herein or the context otherwise requires, all initially capitalized terms used herein without definition shall have the meanings specified in the Credit Agreement.

This Agreement constitutes notice to each of you of the proposed assignment7 and delegation by [insert name of assignor] (the “Assignor”) to [insert name of assignee] (the “Assignee”), and, subject to the terms and conditions of the Credit Agreement, the Assignor hereby sells and assigns to the Assignee, and the Assignee hereby purchases and assumes from the Assignor, effective on the “Effective Date” (as hereafter defined) that undivided interest in each of Assignor’s rights and obligations under the Credit Agreement and the other Loan Documents in the amounts as set forth on the attached Schedule 1, such that, after giving effect to the foregoing assignment and assumption, and the concurrent assignment by Assignor to Assignee on the date hereof, the Assignee’s interest in the Revolving Credit (and participations in any outstanding Letters of Credit and Swing Line Advances) shall be as set forth in the attached Schedule 2 with respect to the Assignee.

The Assignor hereby instructs the Agent to make all payments from and including the Effective Date hereof in respect of the interest assigned hereby, directly to the Assignee. The Assignor and the Assignee agree that all interest and fees accrued up to, but not including, the Effective Date of the assignment and delegation being made hereby are the property of the Assignor, and not the Assignee. The Assignee agrees that, upon receipt of any such interest or fees accrued up to the Effective Date, the Assignee will promptly remit the same to the Assignor.

The Assignee hereby confirms that it has received a copy of the Credit Agreement and the exhibits and schedules referred to therein, and all other Loan Documents which it considers necessary, together with copies of the other documents which were required to be delivered under the Credit Agreement as a condition to the making of the loans thereunder. The Assignee

H - 1

acknowledges and agrees that it: (a) has made and will continue to make such inquiries and has taken and will take such care on its own behalf as would have been the case had its Percentage been granted and its loans been made directly by such Assignee to the Borrower without the intervention of the Agent, the Assignor or any other Lender; and (b) has made and will continue to make, independently and without reliance upon the Agent, the Assignor or any other Lender, and based on such documents and information as it has deemed appropriate, its own credit analysis and decisions relating to the Credit Agreement. The Assignee further acknowledges and agrees that neither the Agent, nor the Assignor has made any representations or warranties about the creditworthiness of the Borrower or any other party to the Credit Agreement or any other of the Loan Documents, or with respect to the legality, validity, sufficiency or enforceability of the Credit Agreement, or any other of the Loan Documents. This assignment shall be made without recourse to or warranty by the Assignor, except as set forth herein.

Assignee represents and warrants that it is a Person to which assignments are permitted pursuant to Section 12.8 of the Credit Agreement.

Except as otherwise provided in the Credit Agreement, effective as of the Effective Date:

(a) the Assignee: (i) shall be deemed automatically to have become a party to the Credit Agreement and the other Loan Documents, to have assumed all of the Assignor’s obligations thereunder to the extent of the Assignee’s percentage referred to in the second paragraph of this Assignment Agreement, and to have all the rights and obligations of a party to the Credit Agreement and the other Loan Documents, as if it were an original signatory thereto to the extent specified in the second paragraph hereof; and (ii) agrees to be bound by the terms and conditions set forth in the Credit Agreement and the other Loan Documents as if it were an original signatory thereto; and

(b) the Assignor’s obligations under the Credit Agreement and the other Loan Documents shall be reduced by the Percentage referred to in the second paragraph of this Assignment Agreement.

As used herein, the term “Effective Date” means the date on which all of the following have occurred or have been completed, as reasonably determined by the Agent:

(a) the delivery to the Agent of an original of this Assignment Agreement executed by the Assignor and the Assignee;

(b) the payment to the Agent, of all accrued fees, expenses and other items for which reimbursement is then owing under the Credit Agreement;

(d) all other restrictions and items noted in Section 12.8 of the Credit Agreement have been completed.

The Agent shall notify the Assignor and the Assignee, along with Borrower, of the Effective Date.
