(c) US LIBOR on such day for a period of one month plus 75 basis points per annum

as to which a certificate of the Administrative Agent, absent manifest error, shall be conclusive evidence from time to time.

“Capital Lease” means a lease of (or other agreement conveying the right to use) real and/or personal property, which lease is required to be classified and accounted for as a capital lease on a balance sheet of the lessee under IFRS, but excluding any operating leases required to be reclassified as capital leases in accordance with any changes to IFRS after the Closing Date.

With respect to that portion of a proposed CDOR Rate Advance being funded by a Lender that is not a bank under Schedule I to the Bank Act (Canada), the CDOR Rate will be the lesser of (i) the CDOR Rate (as determined above) plus one-tenth of one (1/10%) percent; and (ii) the annual rate, expressed as a percentage, determined by the Administrative Agent (on the basis of quotations provided to the Administrative Agent by the Reference Lenders) as the average discount rate for bankers’ acceptances having a comparable face value and a comparable issue and maturity date to the face value and issue and maturity date of that CDOR Rate Advance calculated on the basis of a year of 365 days, accepted by the Reference Lenders at or about 10:00 a.m. (Toronto time) on the funding date of that CDOR Rate Advance.

(e) so long as no default has occurred in respect of such debentures or notes and provided the Borrower is in compliance with all applicable securities Laws and such common shares are qualified for distribution as required and listed on the Toronto Stock Exchange or another national securities exchange, then any and all payments of interest and principal due and payable under such debentures or notes can be satisfied, at the option of the Borrower, by delivering common shares in accordance with the indenture or agreement governing such debentures or notes (whether such common shares are received by the holders of such debentures or notes as payment or are sold by a trustee or representative under such indenture or agreement to provide cash for payment to holders of such debentures or notes);

(2) If:

(a) the Borrower or any of its subsidiaries adopts a material change in an accounting policy in order to more appropriately present events or transactions in its financial statements, and such change would require disclosure under IFRS in the consolidated financial statements of the Borrower; or

(b) the Borrower has made a determination to maintain its accounts in accordance with US GAAP;

and either such event would cause an amount required to be determined for the purposes of the financial covenants in section 10.2(12) or any financial term used in this agreement (each a “Financial Covenant/Term”) to be materially different than the amount that would be determined without giving effect to such change, the Borrower shall notify the Administrative Agent of such change (an “Accounting Change”). Such notice (an “Accounting Change Notice”) shall describe the nature of the Accounting Change, its effect on the current and immediately prior year’s financial statements in accordance with (in the case of (a) above) IFRS or (in the case of (b) above) US GAAP and state whether the Borrower desires to revise the method of calculating one or more of the Financial Covenants/Terms (including the revision of any of the defined terms used in the determination of such Financial/Covenant Term) in order that amounts determined after giving effect to such Accounting Change and the revised method of calculating such Financial Covenant/Term will approximate the amount that would be determined without giving effect to such Accounting Change and without giving effect to the revised method of calculating such Financial Covenant/Term. The Accounting Change Notice shall be delivered to the Administrative Agent within 60 days after the end of the Financial Quarter in which the Accounting Change is implemented or, if such Accounting Change is implemented in the fourth Financial Quarter or in respect of an entire Financial Year, within 120 days after the end of such period. In connection with any Accounting Change Notice, the Borrower shall forthwith provide to the Administrative Agent any additional information regarding the Accounting Change as the Administrative Agent shall reasonably request.

(3) If, pursuant to the Accounting Change Notice, the Borrower does not indicate it desires to revise the method of calculating one or more of the Financial Covenants/Terms, the Majority Lenders may within 30 days after receipt of the Accounting Change Notice notify the Borrower that they wish to revise the method of calculating one or more of the Financial Covenants/Terms that has been affected by the Accounting Change in the manner described above.

(4) If either the Borrower or the Majority Lenders so indicate that they wish to revise the method of calculating one or more of the Financial Covenants/Terms, the Borrower and the Majority Lenders shall in good faith attempt to agree on a revised method of calculating such Financial Covenants/Terms so as to reflect equitably such Accounting Change with the desired result that the criteria for evaluating the Borrower’s financial condition shall be substantially the same after such Accounting Change as if such Accounting Change had not been made. Until the Borrower and the Majority Lenders have reached agreement in writing on such revised method of calculation, all amounts to be determined hereunder shall continue to be determined without giving effect to the Accounting Change. For greater certainty, if no notice of a desire to revise the method of calculating the Financial Covenants/Terms in respect of an Accounting Change is given by either the Borrower or the Majority Lenders within the applicable time period described

39

above, then the method of calculating the Financial Covenants/Terms shall not be revised in response to such Accounting Change and all amounts to be determined pursuant to the Financial Covenants/Terms shall be determined after giving effect to such Accounting Change.

(5) If a compliance certificate is delivered under section 10.1(8)(c) in respect of a Financial Quarter or Financial Year in which an Accounting Change is implemented without giving effect to any revised method of calculating any of the Financial Covenants/Terms, and subsequently, as provided above, the method of calculating one or more of the Financial Covenants/Terms is revised in response to such Accounting Change, or the amounts to be determined pursuant to any of the Financial Covenants/Terms are to be determined without giving effect to such Accounting Change, the Borrower shall deliver a revised compliance certificate. Any Event of Default which arises as a result of the Accounting Change and which is cured by this section 1.3(5) shall be deemed to have never occurred.

1.4 Incorporation of Schedules.

Schedules 1 to 11 annexed hereto shall, for all purposes hereof, form an integral part of this agreement.

1.5 Gender; Singular, Plural, etc.

As used herein, each gender shall include all genders, and the singular shall include the plural and the plural the singular, as the context shall require.

40

1.9 General Provisions as to Certificates and Opinions, etc.

Whenever the delivery of a certificate is a condition precedent to the taking of any action by the Administrative Agent or any Lender hereunder, the truth and accuracy of the facts and the diligent and good faith determination of the opinions stated in such certificate shall in each case be conditions precedent to the right of the Borrower to have such action taken, and any certificate executed by the Borrower shall be deemed to represent and warrant that the facts stated in such certificate are true and accurate

1.10 Existing Accommodations.

For greater certainty, the parties confirm that, at such time as the conditions precedent set forth in section 6.1 have been satisfied, fulfilled or otherwise met to the satisfaction of the Lenders, the obligations outstanding under the Credit Facility (as defined in the Existing Credit Agreement) and described in schedule 7 annexed hereto shall for all purposes constitute Obligations under the Revolving Facility.

(b) the Term Facility, to be made available to the Borrower by the Term Lenders on a non-revolving basis in the principal amount of up to but not exceeding US$500 million (or the Equivalent Amount in Canadian Dollars); provided that:

(i) in the event that the 2012 Notes have been issued by the Borrower prior to the Closing Date or are issued on the Closing Date concurrently with the initial availability of the Term Facility, the maximum principal amount of the Term Facility shall be reduced by an amount equal to the principal amount of the 2012 Notes so issued; and

(ii) any issue of the 2012 Notes after the Closing Date shall require a mandatory prepayment and reduction of the Term Facility in accordance with section 2.3(1)(b).

Subject to the terms and conditions herein set forth, each Lender shall make Accommodations available under a Credit Facility pro rata on the basis of such Lender’s Commitment under such Credit Facility as set forth in schedule 1 annexed hereto.

Subject to section 2.11, in no event shall a Lender be obligated to make Accommodations available under a Credit Facility if after making such Accommodations the US$ Equivalent Principal Outstanding of that Lender’s Accommodations under such Credit Facility would exceed such Lender’s Commitment thereunder.

Any unused amount of the Term Facility shall be permanently canceled as of the close of business on November 2, 2012 and the aggregate Commitments in respect of the Term Facility shall be permanently reduced and canceled in an equal amount (on a pro rata basis among the Term Lenders based upon their respective Commitments). Notwithstanding anything else in this agreement to the contrary, for the purpose of determining the Principal Outstanding under the Term Facility at all times under this agreement, the conversion of the C$ Initial Advance will be made at the exchange rate referenced in the first sentence of this paragraph and the C$ Initial Advance may not be converted or maintained thereafter into or as any other Type of Advance other than a Prime Rate Advance or a CDOR Rate Advance.

(5) Revolving Repayments.

(a) The Revolving Facility is a so-called “revolving” facility and amounts repaid thereunder may be made the subject of a further Accommodation (subject to compliance with the terms and conditions of this agreement); repayments of the Revolving Facility in accordance with its revolving nature shall be made on one Business Day’s notice for Prime Rate Advances, CDOR Rate Advances, and Base Rate Advances, and three Business Days’ notice for US LIBOR Advances.

(b) The Term Facility shall not revolve, and amounts repaid or prepaid thereunder may not be the subject of any further Accommodations (other than by way of Conversions or Rollovers) and shall give rise to a cancellation and reduction of the relevant Commitments as set forth in section 2.4.

(6) Swingline Advances. In the event that the Borrower has a requirement for a Prime Rate Advance or a Base Rate Advance in same day funds in an amount up to US$30 million (or the Equivalent Amount in Canadian Dollars) in the aggregate, the Borrower may (subject to satisfaction of applicable terms and conditions hereof) obtain such Advance (in this section 2.1(6), a “Swingline Advance”) under the Revolving Facility from the Swingline Lender alone. Each Swingline Advance (i) may be made on the same day’s telephone request made on or before 1:00 pm (Toronto time) on such day in the case of Swingline Advances denominated in Canadian Dollars, and 12:00 noon (Toronto time) on such day in the case of Swingline Advances denominated in US Dollars, by the Borrower providing to the Swingline Lender (with a copy to the Administrative Agent) the same information as would be contained in a Borrowing Notice (which shall be deemed to have been so provided), or (ii) shall be made by the Swingline Lender, without notice from or to the Borrower, in respect of any overdraft in any one or more of the Borrower’s accounts with the Swingline Lender by deposit to such account of an amount at least equal to such overdraft. Each Swingline Advance shall be deemed to constitute a utilization of the Revolving Facility funded wholly by the Swingline Lender (and, prior to the repayment of such Swingline Advance with the proceeds of an Accommodation under the Revolving Facility provided by all of the Revolving Lenders, the payments on account thereof shall be allocated wholly to the Swingline Lender) and may not be outstanding more than seven Business Days. The Borrower shall, on or before the seventh Business Day forthwith following the making of a Swingline Advance, repay such Swingline Advance in full, together with all accrued or unpaid interest, either from its own resources or with the proceeds of an Accommodation under the Revolving Facility, failing which the Borrower shall be deemed to have delivered to the Administrative Agent at the close of business in Vancouver on such seventh Business Day an Accommodation Request requesting a Prime Rate Advance or a Base Rate Advance (as the case may be) under the Revolving Facility in the amount of such Swingline Advance. The proceeds of the funding by the other Revolving Lenders under such Accommodation Request shall be applied by the Administrative Agent to repay the Swingline Lender that portion of the Swingline Advance that does not represent the Swingline Lender’s pro rata share (as a Revolving Lender) of the requested Prime Rate Advance or Base Rate Advance. For certainty, it is acknowledged and agreed that the Revolving Lenders shall be obligated to fund their Rateable Portions of any Prime Rate Advance or Base Rate Advance required by this Section 2.1(6) regardless of whether (i) a Default or Event of Default has occurred and is continuing, (ii) an Accommodation Request has actually been delivered by the Borrower or (iii) any other condition in Section 6.2 has been satisfied, fulfilled or otherwise met.

(7) Acquisitions. In the event that (other than with respect to the Acquisition) the Borrower wishes to utilize proceeds of one or more Accommodations under the Revolving Facility to, or to provide funds to any subsidiary, affiliate or other person to, finance an offer to acquire (which shall include an offer to purchase securities, solicitation of an offer to sell securities, an acceptance of an offer to sell securities, whether or not the offer to sell was solicited, or any combination of the foregoing) outstanding securities of any person (the “Target”) which constitutes a “take-over bid” pursuant to applicable corporate or securities legislation (in any case, a “Takeover”), and if the Takeover is, under applicable Law, such as to require the board of directors of the Target to prepare a directors circular or like document that includes either a recommendation to accept or reject the Takeover or a statement that they are unable to make or are not making a recommendation, then either:

44

(a) prior to or concurrently with delivery to the Administrative Agent of any Accommodation Request, the proceeds of which are intended to be utilized as aforesaid, the Borrower shall provide to the Administrative Agent evidence satisfactory to the Administrative Agent (acting reasonably) that the board of directors or like body of the Target, or the holders of all of the securities of the Target, has or have approved, accepted, or recommended to security holders acceptance of, the Takeover;

or:

(b) the following steps shall be followed:

(i) at least five Business Days prior to the delivery to the Administrative Agent of such Accommodation Request, the Borrower shall advise the Administrative Agent (who shall promptly advise each Revolving Lender) of the particulars of such Takeover;

(ii) within three Business Days of being so advised, each Revolving Lender shall notify the Administrative Agent of such Lender’s determination as to whether it is willing to fund under such Accommodation Request; provided that, in the event such Lender does not so notify the Administrative Agent within such three Business Day period, such Lender shall be deemed to have notified the Administrative Agent that it is not so willing to fund; and

(iii) the Administrative Agent shall promptly notify the Borrower of each such Lender’s determination;

and in the event that any Revolving Lender (each, a “Declining Lender”) has notified or is deemed to have notified the Administrative Agent that it is not willing to fund under such Accommodation Request, then such Declining Lender shall have no obligation to fund under such Accommodation Request, notwithstanding any other provision of this agreement to the contrary; provided, however, that each other Revolving Lender (each, a “Financing Lender”) which has advised the Administrative Agent it is willing to fund under such Accommodation Request shall have an obligation, up to the amount of its unused Commitment under the Revolving Facility, to fund under such Accommodation Request, and such funding shall be provided by each Financing Lender in accordance with the ratio, determined prior to the provision of such funding, that the Commitment of such Financing Lender under the Revolving Facility bears to the aggregate the Commitments of all the Financing Lenders under the Revolving Facility.

If Accommodations are provided in the manner contemplated by section 2.1(7)(b) and there are Declining Lenders, subsequent Accommodations under the Revolving Facility shall be funded firstly by Declining Lenders having unused Commitments under the Revolving Facility, and subsequent repayments under the Revolving Facility shall be applied firstly to Financing Lenders, in each case until such time as the proportion that the amount of each Revolving Lender’s Principal Outstanding under the Revolving Facility bears to the aggregate Principal Outstanding under the Revolving Facility is equal to such proportion which would have been in effect but for the application of this section 2.1(7).

45

For greater certainty, in no event shall a Declining Lender be obligated to purchase any participation in accordance with section 14.1(2) to the extent that the shortfall in such Declining Lender’s share of outstanding Obligations under the Revolving Facility is attributable to the operation of this section 2.1(7).

(8) Accordion. Upon written notice to the Administrative Agent, the Borrower may at any time request an increase in the aggregate Commitments under the Revolving Facility of up to US$300 million. The Lenders at the time of such request shall not be obliged to participate in any requested increase and the Borrower may pursue and include new lenders to assist in funding the increase in the Revolving Facility; provided that the addition of new lenders shall be subject to:

(a) the consent of the Administrative Agent and the Fronting Lender;

(b) the provision by the Administrative Agent of notice of the submission by the Borrower of a request under this section 2.1(8) not less than five Business Days’ prior to the date of any increase in the aggregate Commitments; and

(c) the execution and delivery by such new lenders of such accession or similar agreements as may be advised by Lenders’ Counsel in order that such new lenders shall be bound by the terms and conditions of this agreement.

(9) Lending Offices. A Lender may from time to time by written notice to the Administrative Agent (with a copy to the Borrower) make an election to change a Lending Office to another office, branch or location; provided that, unless an Event of Default shall have occurred and be continuing, the consent of the Borrower to a change under this section 2.1(9) shall be required (which consent shall not be unreasonably withheld, it being acknowledged that the Borrower may reasonably object to a change if the result thereof would be to subject the Borrower to a gross-up obligation under section 11.6 or other Increased Costs).

2.2 Repayment.

(1) Credit Facilities Repayment.

(a) Revolving Facility – The Principal Outstanding under the Revolving Facility will be repaid in full on the Final Maturity Date.

(b) Term Facility – The Principal Outstanding under the Term Facility will be repaid as set forth in this section 2.2(1)(b). In this section 2.2(1)(b), the term “Closing Date Balance (Term)” means the Principal Outstanding under the Term Facility at the close of business in Toronto on the Closing Date before giving effect to any payment described in the immediately following items (i) to (v).

(i) On the first anniversary of the last day of the Financial Quarter in which the Closing Date occurs, 5% of the Closing Date Balance (Term) will be repaid;

(ii) On the last day of each of the four Financial Quarters immediately following the payment in (i), 1.25% of the Closing Date Balance (Term) will be repaid;

(iii) On the last day of each of the four Financial Quarters immediately following the last of the payments in (ii), 2.5% of the Closing Date Balance (Term) will be repaid;

46

(iv) On the last day of each of the three Financial Quarters immediately following the last of the payments in (iii), 2.5% of the Closing Date Balance (Term) will be repaid; and

(v) On the Final Maturity Date, the remaining Principal Outstanding under the Term Facility will be repaid in full.

(2) Interest. At the same time as any mandatory or voluntary repayment or prepayment of principal is made hereunder, the Borrower shall also pay all accrued and unpaid interest on the principal amount being repaid or prepaid.

(3) Foreign Exchange Fluctuations. If at any time the US$ Equivalent Principal Outstanding under a Credit Facility (subject in the case of the Term Facility to the last paragraph of section 2.1(3)), as calculated by the Administrative Agent as at the first Business Day of a calendar month, shall exceed 105% of the aggregate Commitments of the Lenders thereunder by virtue of a change in the Equivalent Amount in US Dollars of Accommodations made in any other currencies, the Borrower shall within five Business Days following demand therefor by the Administrative Agent at the Borrower’s election either (i) pay to the Administrative Agent on account of the Principal Outstanding such amount as is required to reduce such US$ Equivalent Principal Outstanding to, or below, such aggregate Commitments, or (ii) pay such excess amount to the Administrative Agent, to be held by the Administrative Agent as cash collateral security for the Obligations under the relevant Credit Facility as they come due.

(4) Exceeding Commitments. Subject to section 2.2(3), if at any time the US$ Equivalent Principal Outstanding under a Credit Facility (subject in the case of the Term Facility to the last paragraph of section 2.1(3)), as calculated by the Administrative Agent, shall exceed the aggregate Commitments of the Lenders under such Credit Facility, the Borrower shall within five Business Days following demand therefor by the Administrative Agent pay to the Administrative Agent such amount as is required to reduce such US$ Equivalent Principal Outstanding to, or below, such aggregate Commitments.

2.3 Mandatory Reductions and Prepayments.

(1) Term Facility. Upon the occurrence of any of events set forth in (a) to (d) below, the Borrower shall be required to apply the net proceeds of such event to the mandatory prepayment of the Term Facility in accordance with the terms of this section 2.3, which prepayment shall permanently reduce the availability of the Term Facility:

(a) subject to section 2.3(3), Asset Dispositions by any MDA Party or MDA Pledgor, excluding Permitted Dispositions; provided that it will not be necessary to effect a mandatory prepayment in the event that, both before and on a pro forma basis after such disposition, the ratio of Consolidated Debt to EBITDA does not exceed 1.75:1 (and, in the event that such ratio does exceed 1.75:1 after such Asset Disposition, it shall be necessary to effect such a prepayment only to the extent necessary to bring such ratio down to 1.75:1); provided further that, in the case of a disposition of Orbital Receivables, it shall be necessary to effect a mandatory prepayment hereunder in the full amount of the net proceeds thereof notwithstanding the said ratio;

(b) the incurrence by any MDA Party of indebtedness for borrowed money, including obligations with respect to bankers’ acceptances, but excluding:

(i) the Credit Facilities;

47

(ii) the 2012 LC Facility (or its replacement);

(iii) proceeds of Purchase Money Mortgages;

(iv) Convertible Debentures; and

(v) transactions between the Borrower and any subsidiary of the Borrower or between subsidiaries of the Borrower; and

(c) the issuance of equity securities by the Borrower; provided that, for the purposes of this section 2.3(1)(c), the issuance of Convertible Debentures shall be deemed to be an issuance of equity securities irrespective of the treatment of same under IFRS; provided further that it will not be necessary to effect a mandatory prepayment:

(i) in respect of an issuance of equity securities to the extent that the proceeds of such equity issuance are used in an acquisition within six months of such issuance, if the pro forma (post-acquisition) ratio of Consolidated Debt to EBITDA (the “Post-Acquisition Ratio”) does not exceed the ratio of Consolidated Debt to EBITDA as reported by the Borrower as at the most recently-completed Financial Quarter (the “Pre-Acquisition Ratio”) (and, in the event that such Post-Acquisition Ratio does exceed such Pre-Acquisition Ratio, it shall be necessary to effect such a prepayment only to the extent necessary to bring such Post-Acquisition Ratio down to such Pre-Acquisition Ratio);

(ii) in any case, in respect of an issuance of equity securities if, both before and on a pro forma basis after such issuance, the ratio of Consolidated Debt to EBITDA does not exceed 1.75:1 (and, in the event that such ratio does exceed 1.75:1 after such issuance, it shall be necessary to effect such a prepayment only to the extent necessary to bring such ratio down to 1.75:1); or

(iii) in respect of the issuance of equity securities pursuant to any equity compensation plan of the Borrower.

(d) subject to section 2.3(3), receipt by the Borrower of any monies by way of a rebate, refund or reduction of the purchase price payable under the Purchase Agreement (including pursuant to litigation or a settlement thereof); provided that it will not be necessary to effect a mandatory prepayment in the event that, both before and on a pro forma basis after such receipt, the ratio of Consolidated Debt to EBITDA does not exceed 1.75:1 (and, in the event that such ratio does exceed 1.75:1 after such receipt, it shall be necessary to effect such a prepayment only to the extent necessary to bring such ratio down to 1.75:1);

(2) Reduction and Repayment. Any reduction in the Commitments, and resulting prepayment, under the Term Facility by virtue of an event described in section 2.3(1) shall be applied or allocated to each Lender in an amount equal to the Prepayment Portion applicable to such Lender of the amount of net proceeds in respect of such event, and shall be applied in inverse order against amounts payable in accordance with section 2.2(1)(b) (excluding any amounts payable on the Final Maturity Date). In the event and to the extent that any one or more holders of Prudential Notes and 2012 Notes shall fail to accept a Prepayment Offer under and as defined in the relevant note purchase agreement, all amounts that would have been used to redeem such Prudential Notes or 2012 Notes under such note purchase agreement shall be used to effect a further prepayment under this section 2.3, which further prepayment will be allocated to the Lenders pro rata on the basis of their respective Principal Outstanding under the Term Facility.

48

(3) Reinvestment. In the event that the Borrower shall effect an Asset Disposition, or receive monies by way of a rebate, refund or reduction of the purchase price payable under the Purchase Agreement (including pursuant to litigation or a settlement thereof), in circumstances where a mandatory prepayment would have been required by section 2.3(1) but for the fact that the Term Facility had been retired in full, the Borrower shall ensure that the proceeds of such Asset Disposition, rebate, refund or reduction shall be reinvested in the Borrower’s business within 180 days of receipt.

2.4 Voluntary Reductions and Prepayments.

(1) Reductions of Revolving Commitments. The Borrower shall have the right at any time and from time to time, without penalty or bonus, upon at least three Business Days’ prior notice to the Administrative Agent in the form of schedule 6 annexed hereto, to terminate the whole or reduce in part on a permanent basis the unused portion of the Commitments of the Revolving Lenders under the Revolving Facility (pro rata among the Revolving Lenders on the basis of their respective Commitments under the Revolving Facility); provided that each partial reduction shall be in an aggregate minimum amount of US$5 million and multiples in excess thereof of US$1 million.

(2) Prepayment of Credit Facilities. In addition to repayments made under the Revolving Facility in accordance with the revolving nature thereof under section 2.1(5)(a), the Borrower shall have the right at any time and from time to time, without penalty or bonus but subject to section 11.5, upon at least three Business Days’ prior notice to the Administrative Agent, to effect a voluntary prepayment on account of the Principal Outstanding under either or both Credit Facilities, which prepayment (subject to the Majority Lenders under the relevant Credit Facility in any specific instance waiving such requirement) shall be in an aggregate minimum amount of $5 million and multiples in excess thereof of $1 million or in the full amount of the Principal Outstanding under such Credit Facility; provided that any prepayment under this section 2.4(2) shall be applied firstly against the Term Facility.

(3) Order. Any prepayment under section 2.4(2) shall reduce the Commitments of the Lenders in respect of the relevant Credit Facility on a permanent basis (pro rata among such Lenders on the basis of their respective Commitments under such Credit Facility), and in the case of the Term Facility shall be applied pro rata against amounts payable in accordance with section 2.2(1)(b) (excluding any amounts payable on the relevant Final Maturity Date).

(4) Return of Letters of Credit. The Borrower may at any time and from time to time, at its option, return any outstanding Letter of Credit to the Fronting Lender for cancellation.

2.5 Payments.

(1) Payment Account. The Borrower shall make each payment to be made hereunder not later than 10:00 a.m. (Vancouver time) in the currency of the Accommodation or other obligation in respect of which such payment is made (be it Canadian Dollars, US Dollars or another currency) on the day (subject to section 2.5(2)) when due, in immediately available funds, by deposit of such funds to the applicable Payment Account.

49

(2) Business Day. Subject to the next following sentence, whenever any payment hereunder is due on a day other than a Business Day, such payment shall be made on the next succeeding Business Day, and such extension of time shall in such case be included in the computation of interest or fees, as the case may be. If any such extension would cause any payment of interest or fees on an Accommodation to be made in the next following calendar month, such payment shall be made on the last preceding Business Day.

(3) Application. Unless otherwise provided herein, all amounts received by the Administrative Agent on account of the Obligations shall be applied by the Administrative Agent as follows:

(a) first, to fulfil the Borrower’s obligation to pay accrued and unpaid interest due and owing (including interest on overdue interest and on other amounts), excluding interest accruing on BA Equivalent Loans;

(b) second, to fulfil the Borrower’s obligation to pay any fees which are due and owing to the Lenders hereunder (including those fees set forth in section 2.7), and any Increased Costs and other unpaid costs, expenses and other amounts payable to the Lenders in connection with any of the Credit Facility Documents;

(c) third, to fulfil the Borrower’s obligation to pay interest accruing on BA Equivalent Loans and any amounts due and owing on account of Principal Outstanding under the Credit Facilities (including in respect of the Face Amount of outstanding Bankers’ Acceptances and Letters of Credit); and

(d) fourth, to the Borrower or as any court of competent jurisdiction may otherwise direct;

and in respect of which each claim at the same level as set forth in paragraph (a), (b) or (c) above shall rank pari passu in all respects.

(4) Pro Rata Basis. All payments of principal, interest and fees to the Lenders, unless otherwise expressly stipulated, shall be made for the account of, and distributed by the Administrative Agent to, the Lenders pro rata on the basis of the amounts respectively owed to them as (as applicable) principal, interest or fees under the relevant Credit Facility.

(5) Netting. If on any date liquidated amounts (other than interest and fees) would be payable under this agreement in the same currency by the Borrower to certain Lenders and by such Lenders to the Borrower, then on such date, at the election of and upon notice from the Administrative Agent stating that netting is to apply to such payments, each such party’s obligations to make payment of any such amount will be automatically satisfied and discharged and, if the aggregate amount that would otherwise have been payable by the Borrower to such Lenders exceeds the aggregate amount that would otherwise have been payable by such Lenders to the Borrower or vice versa, such obligations shall be replaced by an obligation upon the Borrower or such Lenders by whom the larger aggregate amount would have been payable to pay to the other the excess of the larger aggregate amount over the smaller aggregate amount.

(6) Payments Free of Set-off. Except as set forth in section 2.5(5), each payment made by the Borrower on account of the Obligations shall be made without set-off or counterclaim.

50

2.6 Computations.

(1) Basis. All computations of:

(a) interest based on the Prime Rate or the Base Rate shall be made by the Administrative Agent on the basis of a year of 365 days or, in the case of a leap year, 366 days and the actual number of days (including the first day but excluding the last day) occurring in the period for which such interest is payable; and

(b) interest based on US LIBOR shall be made by the Administrative Agent on the basis of a year of 360 days and the actual number of days (including the first day but excluding the last day) occurring in the period for which such interest is payable.

Computation of fees under sections 2.7(a), 4.6 and 5.8(1) and (2) shall be made by the Administrative Agent on the basis of a year of 365 days or (in the case of a leap year and only with respect to fees under sections 2.7(a) and 5.8(1) and (2)) 366 days and the actual number of days (including the first day but excluding the last day) occurring in the period for which such fees are payable. Each determination by the Administrative Agent of an amount of interest, Discount Proceeds or fees payable by the Borrower hereunder shall be conclusive and binding for all purposes, absent demonstrated error.

(2) Interest Act (Canada).

(a) For purposes of disclosure pursuant to the Interest Act (Canada), the yearly rate of interest to which any rate of interest based on US LIBOR is equivalent may be determined by multiplying the applicable rate by a fraction, the numerator of which is the number of days to the same calendar date in the next calendar year (or 365 days if the calculation is made as of February 29) and the denominator of which is 360.

(b) In no event shall aggregate “interest” as defined in Section 347 of the Criminal Code, R.S.C. 1985, c. C-46 (as the same shall be amended, replaced or re-enacted from time to time) payable by the Borrower to the Administrative Agent or any Lender under this agreement or any other Credit Facility Document exceed the effective annual rate of interest on the “credit advanced” (as defined in that section) under this agreement or such other Credit Facility Document lawfully permitted under that section and, if any payment, collection or demand pursuant to this agreement or any other Credit Facility Document in respect of “interest” (as defined in that section) is determined to be contrary to the provisions of that section, such payment, collection or demand shall be deemed to have been made by mutual mistake of the Administrative Agent, the Lenders and the Borrower. For the purposes of this agreement and each other Credit Facility Document to which the Borrower is a party, the effective annual rate of interest payable by the Borrower shall be determined in accordance with generally accepted actuarial practices and principles over the term of the loans on the basis of annual compounding for the lawfully permitted rate of interest and, in the event of dispute, a certificate of a Fellow of the Canadian Institute of Actuaries appointed by the Administrative Agent for the account of the Borrower will be conclusive for the purpose of such determination in the absence of evidence to the contrary.

2.7 Fees.

The Borrower shall pay to the Administrative Agent the following fees, calculated as follows:

(a) a standby fee (for the account of the Revolving Lenders pro rata on the basis of their respective Commitments under the Revolving Facility) payable by the Borrower at the rate per annum equal to the applicable percentage set forth in

51

the definition of Applicable Margin, calculated on the difference from time to time between the aggregate Commitments under the Revolving Facility (as reduced in accordance with section 2.4) and the aggregate Principal Outstanding under the Revolving Facility (excluding Swingline Advances); such fee shall be payable in US Dollars, calculated daily from the Closing Date to the Final Maturity Date, and payable quarterly in arrears on the first day of each January, April, July, and October and on the Final Maturity Date; and

(b) the fees agreed with the Administrative Agent in a letter of even date.

2.8 Interest on Overdue Amounts.

Except as otherwise provided in this agreement, each amount owed by the Borrower to a Lender which is not paid when due (whether at stated maturity, on demand, by acceleration or otherwise) shall bear interest (both before and after judgment), from the date on which such amount is due until such amount is paid in full, payable on demand, at a rate per annum equal at all times to the Base Rate (in the case of amounts denominated in US Dollars) or the Prime Rate (in the case of amounts denominated in Canadian Dollars), in each case plus two (2%) percent per annum in excess of the Applicable Margin.

2.9 Where Borrower Fails to Pay.

Unless the Administrative Agent has been notified in writing by the Borrower at least one Business Day prior to the date on which any payment to be made by the Borrower hereunder is due that the Borrower does not intend to remit such payment, the Administrative Agent may, in its discretion, assume that the Borrower has remitted such payment when so due and the Administrative Agent may, in its discretion and in reliance upon such assumption, make available to each relevant Lender on such payment date an amount equal to the portion of such payment which is due to such Lender pursuant to this agreement. If the Borrower does not in fact remit such payment to the Administrative Agent, the Administrative Agent shall promptly notify each such Lender and such Lender shall forthwith on demand repay to the Administrative Agent an amount equal to the portion of such assumed payment made available to such Lender, together with interest thereon until the date of repayment thereof at a rate determined by the Administrative Agent (such rate to be conclusive and binding on such Lender) in accordance with the Administrative Agent’s usual banking practice for similar advances to financial institutions of like standing as such Lender but in no event greater than, as the case may be, the Prime Rate or the Base Rate.

2.10 Account Debit Authorization.

The Borrower authorizes and directs the Administrative Agent, in its discretion, to automatically debit, by mechanical, electronic or manual means, all bank accounts of the Borrower maintained with the Administrative Agent for all amounts due and payable under this agreement on account of principal, interest and fees hereunder comprised in the Obligations.

2.11 Administrative Agent’s Discretion on Allocation.

In the event that it is not practicable to:

(a) allocate to each relevant Lender its Rateable Portion of an Accommodation in accordance with section 3.2 or 4.1(2) by reason of the occurrence of circumstances described in Article 11; or

(b) allocate a Drawing among the relevant Lenders in accordance with section 4.1(2) such that the aggregate amount of Bankers’ Acceptances required to be accepted hereunder complies with the minimum amounts or increments set forth in section 2.1(4);

52

the Administrative Agent is authorized by the Borrower and each relevant Lender to make such allocation as the Administrative Agent determines in its sole and unfettered discretion may be equitable in the circumstances. All fees in respect of and repayments in connection with any such Accommodation, as well as future Accommodations, shall be adjusted as among the relevant Lenders by the Administrative Agent accordingly.

2.12 Rollover and Conversion.

(1) General. Subject to the terms and conditions of this agreement, the Borrower may from time to time request that any Bankers’ Acceptance or type of Advance or any portion thereof be rolled over or converted in accordance with the provisions hereof.

(2) Request. Each request by the Borrower for a Rollover or Conversion shall be made by the delivery of a duly completed and executed Accommodation Request to the Administrative Agent and the provisions of Article 3 or Article 4 shall apply to each request for a Rollover or Conversion as if such request were a request thereunder for a Borrowing or a Drawing (as the case may be).

(3) Effective Date. Each Rollover or Conversion of a CDOR Rate Advance, a US LIBOR Advance or Bankers’ Acceptance shall be made effective as of, in the case of a CDOR Rate Advance or a LIBOR Advance, the last day of the subsisting Interest Period and, in the case of a Bankers’ Acceptance, the maturity date applicable thereto.

(4) Failure to Elect. If the Borrower does not deliver an Accommodation Request at or before the time required by section 2.12(2) and:

(a) in the case of a Bankers’ Acceptance fails to give three Business Days prior notice that it will pay to the Administrative Agent for the account of the applicable Lender the Face Amount thereof on the maturity date or if the Borrower gives such notice but fails to act in accordance with it, the Borrower shall be deemed to have requested a Conversion of the Face Amount thereof to a Prime Rate Advance and all of the provisions hereof relating to a Prime Rate Advance shall apply thereto;

(b) in the case of a CDOR Rate Advance, fails to give two Business Days prior notice that it will pay to the Administrative Agent for the account of the applicable Lender the principal amount thereof at the end of the relevant Interest Period or if the Borrower gives such notice but fails to act in such accordance with it, the Borrower shall be deemed to have requested a Rollover of such Advance for a further Interest Period of one¹ month, and all of the provisions hereof applicable to CDOR Rate Advances shall apply thereto; or

(c) in the case of a US LIBOR Advance, fails to give three Business Days prior notice that it will pay to the Administrative Agent for the account of the applicable Lender the principal amount thereof at the end of the relevant Interest Period or if the Borrower gives such notice but fails to act in such accordance with it, the Borrower shall be deemed to have requested a Rollover of such Advance for a further Interest Period of one month, and all of the provisions hereof applicable to US LIBOR Advances shall apply thereto.

¹  Please note that the Second Amendment to the 2012 Credit Agreement dated May 14, 2014, called for replacement of the word “one” with the word “two” in this Section 2.12(4)(b). We have assumed this only referred to the first instance of the word “one”, and have left the second instance unchanged.

53

2.13 Extensions of Final Maturity Date.

(1) The Borrower may, at its option, by delivering to the Administrative Agent a written extension request, request the Lenders to extend the Final Maturity Date, provided that (a) this request cannot be made more than once in any calendar year and (b) the requested Final Maturity Date not exceed four years from the effective date of such requested extension.

(2) Promptly after receipt from the Borrower of an executed extension request, the Administrative Agent shall deliver to each Lender a copy of such request, and each such Lender shall, within 30 days after receipt of such extension request (the “Election Date”), advise the Administrative Agent in writing whether such Lender will agree to extend its Final Maturity Date; provided that if any Lender fails to so advise the Administrative Agent by the Election Date, then such Lender shall be deemed to have advised the Administrative Agent that it will not agree to extend its Final Maturity Date. The Administrative Agent shall promptly notify the Borrower if any Lender advises that it will not agree to extend its Final Maturity Date. Subject to any replacement of Non-Extending Lenders under Section 11.7, the Administrative Agent shall only extend the Final Maturity Date upon the agreement of the Majority Lenders, and any such extension shall apply only to those Lenders which provided their consent to such extension (the “Extending Lenders”). The determination of each Lender whether or not to extend the Final Maturity Date applicable to it shall be made by each individual Lender in its sole discretion.

(3) As soon as all of the Lenders have advised, or are deemed to have advised, the Administrative Agent whether or not they will be extending the Final Maturity Date, the Agent shall either:

(a) deliver to the Borrower (with a copy to each such Lender) a written extension signed by the Administrative Agent; or

(b) notify the Borrower that the request for extension has been denied.

(4) If the extension is approved by less than all of the Lenders, then the Administrative Agent shall also advise the Borrower of any Lender(s) which did not agree to the requested extension (each, a “Non-Extending Lender”), each Non-Extending Lender’s Rateable Portion of the Obligations then outstanding and the amount, if any, by which each Extending Lender is prepared to increase its Commitment in the event the Borrower proposes to assign the Commitment of a Non-Extending Lender under Section 11.7.

(5) Upon the delivery to the Borrower of a written extension, the current Final Maturity Date of the Extending Lenders shall be extended for up to four years as specified in such written extension and the current Final Maturity Date for the Non-Extending Lenders will remain unchanged.

(6) Each Non-Extending Lender shall be deemed to be an Affected Lender for the purposes of Section 11.7.

(7) Clauses (1) through (6) of this Section 2.13 shall apply from time to time to permit successive extensions to the Final Maturity Date prior to the then current Final Maturity Date of the Extending Lenders; provided that, unless agreed otherwise by the Borrower, the Administrative Agent and any Non-Extending Lender, such Non-Extending Lender shall be excluded from this Section 2.13 with respect to any future extensions.

54

Article 3

ADVANCES

3.1 Advances.

(1) Commitments.

(a) Each Revolving Lender agrees (on a several basis with the other Revolving Lenders, up to the amount of such Lender’s Commitment under the Revolving Facility), on the terms and conditions herein set forth, to make Advances under the Revolving Facility.

(b) Each Term Lender agrees (on a several basis with the other Term Lenders, up to the amount of such Lender’s Commitment under the Term Facility), on the terms and conditions herein set forth, to make an Advance under the Term Facility on the Closing Date.

(2) Amounts; Availability. The aggregate principal amount of each Borrowing shall comply with, and the availability thereof shall be subject to, section 2.1(4).

3.2 Making the Advances.

(1) Notice. Each Borrowing shall be made on at least three Business Days’ (in the case of US LIBOR Advances) or two Business Days’ (in the case of CDOR Rate Advances) or one Business Day’s (in the case of other types of Advance) prior notice given not later than 10:00 a.m. (Local Time) by the Borrower to the Administrative Agent, and the Administrative Agent shall give to each relevant Lender prompt notice thereof and of such Lender’s Rateable Portion of each type of Borrowing to be made under the Borrowing. Each such notice of a Borrowing shall be given by way of an Accommodation Request or by telephone (confirmed promptly in writing), with the same information as would be contained in an Accommodation Request, including the requested date of such Borrowing and the aggregate amount of each type of Advance comprising such Borrowing.

(2) Lender Funding. Except in connection with a Rollover or Conversion (other than a Conversion from one currency to another), each Lender shall, before 10:00 a.m. (Local Time) on the date and in the currency of the requested Borrowing, deposit to the applicable Payment Account in immediately available funds such Lender’s Rateable Portion (subject to section 2.11) of each type of Advance comprising such Borrowing. Promptly upon receipt by the Administrative Agent of such funds and upon fulfilment of the applicable conditions set forth in Article 6, the Administrative Agent will make such funds available to the Borrower by debiting the Payment Account (or causing such account to be debited), and by crediting such account as the Borrower shall designate (or causing such account to be credited) with such Advances.

(3) Failure by Lender to Fund. Unless the Administrative Agent shall have received notice from a Lender prior to the date of any Borrowing that such Lender will not make available to the Administrative Agent such Lender’s Rateable Portion of each type of Advance comprising such Borrowing, the Administrative Agent may assume that such Lender has made each such Rateable Portion available to the Administrative Agent on the date of such Borrowing in accordance with section 3.2(2) and the Administrative Agent may, in reliance upon such assumption, make available to the Borrower on such date corresponding amounts. If and to the extent that such Lender shall not have made its Rateable Portion available to the Administrative Agent, such Lender shall pay such corresponding amounts to the Administrative Agent forthwith on demand. If such Lender

55

shall pay such corresponding amounts to the Administrative Agent, the amounts so paid shall constitute such Lender’s Rateable Portion of such Borrowing for the purposes of this agreement. The Administrative Agent shall also be entitled to recover from such Lender interest on such corresponding amounts, for each day from the date such amounts were made available by the Administrative Agent to the Borrower until the date such amounts are repaid to the Administrative Agent, at a rate determined by the Administrative Agent (such rate to be conclusive and binding on such Lender) in accordance with the Administrative Agent’s usual banking practice for similar advances to financial institutions of like standing as such Lender but in no event greater than, as the case may be, the Prime Rate or the Base Rate, together with the Administrative Agent’s reasonable administrative fee. If such Lender shall not pay such corresponding amounts to the Administrative Agent forthwith on demand, the Borrower shall pay such corresponding amounts (together with accrued and unpaid interest at the applicable rate herein set forth for each type of Advance) to the Administrative Agent within two Business Days of demand being made upon it.

(4) Ibid. The Administrative Agent shall notify the Borrower of the failure of any Lender to make an Advance if:

(a) such failure has not been remedied within seven days; or

(b) the Administrative Agent reasonably believes that such failure was caused by any reason other than a technical failure or as a result of a defect in the arrangements hereunder for funding Advances.

The Administrative Agent shall not be liable to the Borrower or any Lender in respect of notice given or not given pursuant to this section 3.2(4). In the event of the continuing failure by any Lender (in this section 3.2(4), the “defaulting Lender”) to make an Advance, the Borrower and the Administrative Agent shall use their reasonable best efforts to arrange for one or more other persons (in this section 3.2(4), the “assuming Lender”) reasonably satisfactory to the Borrower and the Administrative Agent to assume all or a portion of the relevant Commitments and acquire the outstanding Accommodations and other rights and interests of the defaulting Lender hereunder. The assuming Lender and defaulting Lender shall execute all such documents as may be reasonably required by the Administrative Agent and the Borrower to effect such assumption and acquisition.

3.3 Interest on Advances.

The Borrower shall pay interest on the unpaid principal amount of each Advance at the following rates per annum:

(a) Prime Rate Advances. If and so long as such Advance is a Prime Rate Advance, at a rate per annum equal at all times to the sum of the Prime Rate in effect from time to time plus the Applicable Margin, calculated daily and payable in Canadian Dollars in arrears:

(i) monthly on the last Business Day of each month; and

(ii) when such Prime Rate Advance becomes due and payable in full or is the subject of a Conversion.

(b) CDOR Rate Advances. If and so long as such Advance is a CDOR Rate Advance, at a rate per annum equal at all times during each Interest Period for such CDOR Rate Advance to the sum of the CDOR Rate for such Interest Period plus the Applicable Margin, calculated daily and payable in Canadian Dollars:

56

(i) at the end of each Interest Period (except where such Interest Period exceeds three months in duration, in which case such interest shall be payable on the dates falling every three months following the commencement of the Interest Period and, finally, at the end of such Interest Period); and

(ii) when such CDOR Rate Advance becomes due and payable in full or is the subject of a Conversion.

(c) Base Rate Advances. If and so long as such Advance is a Base Rate Advance, at a rate per annum equal at all times to the sum of the Base Rate in effect from time to time plus the Applicable Margin, calculated daily and payable in US Dollars in arrears:

(i) monthly on the last Business Day of each month; and

(ii) when such Base Rate Advance becomes due and payable in full or is the subject of a Conversion.

(d) US LIBOR Advances. If and so long as such Advance is a US LIBOR Advance, at a rate per annum equal at all times during each Interest Period for such US LIBOR Advance to the sum of US LIBOR for such Interest Period plus the Applicable Margin, calculated daily and payable in US Dollars:

(i) at the end of each Interest Period (except where such Interest Period exceeds three months in duration, in which case such interest shall be payable on the dates falling every three months following the commencement of the Interest Period and, finally, at the end of such Interest Period); and

(ii) when such US LIBOR Advance becomes due and payable in full or is the subject of a Conversion.

Article 4

BANKERS’ ACCEPTANCES

4.1 Acceptances.

(1) Commitment. Each Lender agrees (on a several basis with the other Lenders, up to the amount of such Lender’s Commitment under the relevant Credit Facility), on the terms and conditions herein set forth, to create and purchase Bankers’ Acceptances under the Credit Facilities.

(2) Amounts. Each Drawing shall be in a Face Amount not less than the minimum amount (or requisite multiple in excess thereof) set forth in, and the availability thereof shall be subject to, section 2.1(4), and such Drawing shall consist of the creation of Bankers’ Acceptances, effected or arranged by the relevant Lenders in accordance with section 4.4, rateably according to their respective relevant Commitments (subject to section 2.11).

57

4.2 Drawdown Request.

(1) Notice. Each Drawing shall be made on at least two Business Days’ prior notice, given not later than 10:00 a.m. (Vancouver time) by the Borrower to the Administrative Agent and the Administrative Agent shall give to each Lender prompt notice thereof and of such Lender’s Rateable Portion thereof (subject to section 2.11). Each such notice of a Drawing shall be given by way of an Accommodation Request or by telephone (confirmed promptly in writing) with the same information as would be contained in an Accommodation Request, including the requested Drawing Date and the Face Amounts of the Bankers’ Acceptances.

(2) Maturity. The Borrower shall not request in an Accommodation Request a term for Bankers’ Acceptances which would end on a date subsequent to the Final Maturity Date or that would conflict with any repayment stipulated herein.

4.3 Form of Bankers’ Acceptances.

(1) Form. Each Bankers’ Acceptance shall:

(a) be in a Face Amount allowing for conformance with section 4.1(2);

(b) be dated the Drawing Date;

(c) mature and be payable by the Borrower (in common with all other Bankers’ Acceptances created in connection with such Drawing) on a Business Day which occurs approximately 30 to 180 days after the date thereof or such other periods as shall be acceptable to the relevant Lender(s), in each case subject to availability; and

(d) be in a form satisfactory to the relevant Lender(s).

(2) Applicability of DBNA. It is the intention of the parties that, unless the Lender is utilizing a non-interest bearing bill of exchange as defined in the Bills of Exchange Act (Canada), each Bankers’ Acceptance accepted by a Lender under this agreement shall be issued in the form of a “depository bill” (as that term is defined in the Depository Bills and Notes Act (Canada) (the “DBNA”)), be deposited with CDS Clearing and Depository Services Inc. and be made payable to “CDS & Co.” The Administrative Agent and the Lenders shall effect the following practices and procedures and, subject to the approval of the Majority Lenders under the applicable Credit Facility, establish and notify the Borrower and the Lenders of any additional procedures, consistent with the terms of this agreement and the requirements of the DBNA, as are reasonably necessary to accomplish this intention:

(a) each Bankers’ Acceptance accepted and purchased by a Lender hereunder shall have marked prominently and legibly on its face and within its text, at or before the time of issue, the words “This is a depository bill subject to the Depository Bills and Notes Act”;

(b) any reference to authentication of that Bankers’ Acceptance will be removed; and

(c) that Bankers’ Acceptance shall not be marked with any words prohibiting negotiation, transfer or assignment of it or of an interest in it.

(3) Grace. The Borrower hereby waives presentment for payment and any other defence to payment of any amounts due in respect of any Bankers’ Acceptance, and hereby renounces, and shall not claim, any days of grace for the payment of any Bankers’ Acceptance.

58

4.4 Completion of Bankers’ Acceptance.

Upon receipt of the notice from the Administrative Agent pursuant to section 4.2(1), each relevant Lender is thereupon authorized to execute Bankers’ Acceptances as the duly authorized attorney of the Borrower pursuant to section 4.8, in accordance with the particulars provided by the Administrative Agent.

4.5 Proceeds.

In the case of a Drawing, each relevant Lender shall, for same day value on the Drawing Date specified by the Borrower in the applicable Drawing Notice, credit the Payment Account with the applicable Discount Proceeds of the Bankers’ Acceptances purchased by such Lender for the account of the Borrower.

4.6 Stamping Fee.

The Borrower shall pay to each relevant Lender a stamping fee in Canadian dollars. Such stamping fee shall be payable by the Borrower in advance, on the Drawing Date, and shall be calculated on the Face Amount of such Bankers’ Acceptances on the basis of the number of days in the term of such Bankers’ Acceptances (including the Drawing Date but excluding the maturity date) at a rate per annum equal to the applicable percentage set forth in the definition of Applicable Margin. The parties acknowledge that, inasmuch as the Discount Proceeds are net of the stamping fee, the Borrower shall be deemed to have paid the stamping fee to a Lender upon that Lender paying the applicable Discount Proceeds pursuant to section 4.5.

4.7 Payment at Maturity.

The Borrower shall pay to the Administrative Agent, and there shall become due and payable, on the maturity date for each Bankers’ Acceptance an amount in immediately available funds equal to the Face Amount of the Bankers’ Acceptance. The Borrower shall make each payment hereunder in respect of Bankers’ Acceptances by deposit of the required funds to the applicable Payment Account. Upon receipt of such payment, the Administrative Agent will promptly thereafter cause such payment to be distributed to the relevant Lenders in like funds relating to the payment of Bankers’ Acceptances rateably (based on the proportion that the Face Amount of Bankers’ Acceptances accepted by a relevant Lender maturing on the relevant date bears to the Face Amount of Bankers’ Acceptances accepted by all relevant Lenders maturing on such date). Such payment to the Administrative Agent shall satisfy the Borrower’s obligations under a Bankers’ Acceptance to which it relates and the accepting institution shall thereafter be solely responsible for the payment of such Bankers’ Acceptance.

Unless the Borrower notifies the Administrative Agent prior to 10:00 a.m. (Vancouver time) two Business Days’ immediately prior to the maturity date of a Bankers’ Acceptance that the Borrower intends to pay to the Administrative Agent the Face Amount thereof with funds other than the proceeds of Advances, (i) the Borrower shall be deemed to have given an Accommodation Request to the Administrative Agent under the relevant Credit Facility requesting the relevant Lenders to make a Prime Rate Advance on such maturity date in an amount equal to such Face Amount, and (ii) the relevant Lenders shall, on such maturity date, make such Prime Rate Advance and apply the proceeds thereof to payment of such Face Amount.

4.8 Power of Attorney Respecting Bankers’ Acceptances.

In order to facilitate issues of Bankers’ Acceptances pursuant to this agreement, the Borrower authorizes each Lender, and for this purpose appoints each Lender its lawful attorney (with full power of substitution), to complete, sign and endorse drafts issued in accordance with section 4.4 on its behalf in

59

handwritten or by facsimile or mechanical signature or otherwise and, once so completed, signed and endorsed, and following acceptance of them as Bankers’ Acceptance under this agreement, then purchase, discount or negotiate such Bankers’ Acceptances in accordance with the provisions of this Article 4. Drafts so completed, signed, endorsed and negotiated on behalf of the Borrower by any Lender shall bind the Borrower as fully and effectively as if so performed by an authorized officer of the Borrower.

No such Lender shall be liable for any damage, loss or other claim arising by reason of any loss or improper use of any draft or Bankers’ Acceptances executed in blank except any such damage, loss or claim arising by reason of the gross negligence, wilful misconduct or fraud of such Lender or its officers, employees, agents or representatives or arising by reason of such Lender or its officers, employees, agents or representatives failing to exercise such care in the custody and safekeeping of such draft or Bankers’ Acceptances as it would exercise in the custody and safekeeping of similar property owned by it.

4.9 Prepayments.

Except as required by section 2.2(3) or (4), 2.3 or 4.10, no payment of the Face Amount of a Bankers’ Acceptance shall be made by the Borrower to a Lender prior to the maturity date thereof. Any such required payment made before the applicable maturity date shall be held in an interest bearing account by the Administrative Agent as cash collateral security to provide for or to secure payment of the Face Amount of such outstanding Bankers’ Acceptance upon maturity, and the Borrower hereby irrevocably authorizes and directs the Administrative Agent to apply such amount on the maturity date for the relevant Drawing to the repayment of the relevant Bankers’ Acceptance. Interest on amounts held on deposit by the Administrative Agent for such deposits shall be paid to the Borrower on the maturity date for the relevant Drawing; provided that, if an Event of Default has occurred, such interest shall be retained by the Administrative Agent and applied to the Obligations. Any such required payment made before the applicable maturity date by the Borrower to the Administrative Agent shall satisfy the Borrower’s obligations under the Bankers’ Acceptance to which it relates. The accepting institution shall thereafter be solely responsible for the payment of the Bankers’ Acceptance and shall indemnify and hold the Borrower harmless against any liabilities, costs or expenses incurred by the Borrower as a result of any failure by such Lender to pay the Bankers’ Acceptance in accordance with its terms.

4.10 Default.

Upon the occurrence of an Event of Default and the Administrative Agent declaring the Obligations to be due and payable pursuant to section 12.2, and notwithstanding the date of maturity of any outstanding Bankers’ Acceptances, an amount equal to the Face Amount of all outstanding Bankers’ Acceptances which the Lenders are required to honour shall thereupon forthwith become due and payable by the Borrower to the Administrative Agent.

4.11 Non-Acceptance Lenders.

The parties acknowledge that a Lender (a “Non-Acceptance Lender”) may not be permitted by applicable Law to, or may not by virtue of customary market practices, stamp or accept commercial drafts. A Non-Acceptance Lender shall, in lieu of accepting and purchasing Bankers’ Acceptances on a Drawing, make a BA Equivalent Loan.

The amount of each BA Equivalent Loan shall be equal to the Discount Proceeds which would be realized from a hypothetical sale of those Bankers’ Acceptances which that Non-Acceptance Lender would otherwise be required to accept and purchase as part of such Drawing. To determine the amount of those Discount Proceeds, the hypothetical sale shall be deemed to take place at the Non-Acceptance Discount Rate for that BA Equivalent Loan.

Any BA Equivalent Loan shall be made on the relevant Drawing Date, and shall remain outstanding for the term of the relevant Bankers’ Acceptances.

60

For greater certainty, concurrently with the making of a BA Equivalent Loan, a Non-Acceptance Lender shall be entitled to deduct therefrom an amount equal to the stamping fee which that Lender would otherwise be entitled to receive pursuant to section 4.6 as part of that BA Equivalent Loan if that BA Equivalent Loan was a Bankers’ Acceptance, based on the amount of principal and interest payable on the maturity date of that BA Equivalent Loan. The parties acknowledge that, inasmuch as Discount Proceeds are net of the stamping fees, no further deduction from the BA Equivalent Loan will be necessary on account of the amount equal to such stamping fee.

On the maturity date for the Bankers’ Acceptances required by the Borrower, the Borrower shall pay to each Non-Acceptance Lender the amount of such Lender’s BA Equivalent Loan plus interest on the principal amount of that BA Equivalent Loan calculated at the applicable Non-Acceptance Discount Rate (in effect the date such BA Equivalent Loan was made) from the date of acceptance to but excluding the maturity date of that BA Equivalent Loan.

(b) for greater certainty and without limiting the generality of section 14.1, the Principal Outstanding among the Revolving Lenders shall be adjusted in the circumstances and in the manner contemplated by section 14.1 in order to reflect the Issuance by the Fronting Lender on behalf of the Revolving Lenders.

77

(vi) any lease, license or other agreement or any property subject to a Purchase Money Security Interest, Capital Lease obligation or similar arrangements, in each case, to the extent permitted under the Credit Facility Documents to the extent that a grant of a security interest therein would violate or invalidate such lease, license or agreement, purchase money, capital lease or a similar arrangement or create a right of termination in favour of any other party thereto (other than any MDA Party) after giving effect to the applicable anti-assignment provisions of the PPSA, UCC or other applicable Law, other than proceeds and receivables thereof, the assignment of which is expressly deemed effective under applicable Law notwithstanding such prohibition;

78

(vii) any property and assets the pledge of which would require governmental consent, approval, license or authorization that has not been obtained;

(viii) those assets as to which the Administrative Agent and the Borrower reasonably agree that the costs of obtaining such a security interest or perfection thereof are excessive in relation to the value to the Lenders of the security to be afforded thereby; provided that, in the case of clauses (v)(B), (vi) and (vii), such exclusion shall not apply:

(xi) any inventory that is “specifically identified to contracts-in-process” as such phrase is used in the footnotes to the financial statements of Loral attached as Schedule 4.7(a) to the Purchase Agreement, where the granting of a Lien over such inventory would result in the breach of a contract;

(b) no control agreements will be required over any deposit accounts or securities accounts except as required to comply with section 10.2(14);

(1) In the event that the Borrower receives a Rating of “Baa3” from Moody’s or “BBB-” from S&P, then:

provided, however (and for the avoidance of doubt), if the Borrower receives a Rating from both Moody’s and S&P, then for purposes of this section 8.8(1), the lower of the two Ratings shall apply to these provisions; provided further that, to the extent any consideration is paid or given to any lender or other creditor under any of the Intercreditor Agreement, the Prudential Note Agreement, the 2012 Note Agreement or any other applicable Credit Document in connection with any such release, discharge or return described above, the Borrower shall pay or provide to the Lenders equivalent consideration, determined based upon the respective amounts of credit provided under this agreement and such other Credit Document receiving such consideration, and on a pro rata basis.

(2) In the event that, following any release of security pursuant to section 8.8(1), (i) the Borrower shall fail to maintain a Rating of “Baa3” from Moody’s or “BBB-” from S&P (and, for the avoidance of doubt, if the Company receives a Rating on its unsecured Debt from both Moody’s and S&P, then the lower of the two Ratings shall apply for purpose of this clause (i)), or (ii) the Borrower shall fail to maintain any Rating from either of Moody’s or S&P, then:

(e) upon receipt of such request by the Borrower, the Borrower shall be under no further obligation to maintain a Rating from either of Moody’s or S&P.

(3) If any MDA Party or MDA Pledgor makes or proposes to make an Asset Disposition permitted hereunder, then:

Neither the Collateral Agent nor the Administrative Agent shall be responsible for any loss by reason of the failure to maintain or insufficiency of any insurance or by reason of the failure of any insurer to pay the full amount of any loss against which such insurer may have insured.

(b) after the Collateral shall have been disposed of by the Collateral Agent or the Secured Parties or any receiver to any third party or parties in the course of realization on the Security; except where such Claims arise by reason of any act or omission of or by the relevant MDA Party, or of or by the Collateral Agent or the Secured Parties or a receiver (if the Collateral Agent or the Secured Parties or the receiver would have been entitled to indemnification hereunder if such Claims had been raised prior to such disposition), occurring prior to the disposition.

(13) Material Contracts. It will, and will cause each Designated Subsidiary to, comply with, and diligently enforce, all material obligations under material contracts, save where failure to do so neither has, nor would reasonably be expected to have, an MAE, and without limiting the generality of the foregoing will use reasonable commercial efforts to cure any matter referred to in a notice given under section 10.1(9).

(14) Acquisitions. The Borrower will provide 15 Business Days’ prior written notice to the Administrative Agent of any proposed acquisition or investment in a person (other than an MDA Party) by the Borrower or any subsidiary for a purchase price or investment in excess of $100 million, together with:

Within 45 days after the end of any Financial Quarter where EBITDA (calculated only with respect to the Borrower and the Designated Subsidiaries), as at the end of such Financial Quarter on the basis of the four Financial Quarters then ended, comprises less than 85% of EBITDA (excluding, for greater certainty, Non-Recourse Subsidiaries) (provided that, for this purpose, the EBITDA of an MDA Party shall be reduced by the portion thereof attributable (determined on a basis satisfactory to the Lenders, acting reasonably) to assets which are subject to a Permitted Lien of the nature

86

described in item (o) or (p) thereof in priority to the Lien of the Security) then the Borrower shall designate as Designated Subsidiaries such one or more additional subsidiaries as would have been sufficient to achieve compliance with the foregoing 85% threshold had such subsidiaries been Designated Subsidiaries throughout the relevant period(s). In addition, the Borrower shall concurrently cause to be provided such additional Security as shall be required by section 8.1 and 8.2.

(19) Intellectual Property.

(a) Each Lender and the Administrative Agent (for itself and not on behalf of any Lender) hereby notifies the Borrower that pursuant to the requirements of the Proceeds of Crime (Money Laundering) and Terrorist Financing Act (Canada), the PATRIOT Act or any other applicable anti-money laundering, anti-terrorist financing, government sanction and “know your client” Applicable Laws (collectively, including any guidelines or orders thereunder, “AML Legislation”), it may be required to obtain, verify and record information that identifies the Borrower and each subsidiary of the Borrower, which information includes the name and address of each such person and such other information that will allow such Lender or the Administrative Agent, as applicable, to identify each such person in accordance with AML Legislation (including information regarding such person’s directors, authorized signing officers, or other persons in control of each such person). The Borrower shall provide, to the extent commercially reasonable, such information and take such actions as are reasonably requested by the Administrative Agent or any Lender in order to assist the Administrative Agent and the Lenders in maintaining compliance with AML Legislation. The Borrower shall promptly provide all such information, including supporting documentation and other evidence, as may be reasonably requested by any Lender or the Administrative Agent (for itself and not on behalf of any Lender), or any prospective assignee of a Lender or the Administrative Agent, in order to comply with any applicable AML Legislation, whether now or hereafter in existence.

(b) Notwithstanding anything to the contrary in this section 10.1(20), each of the Lenders agrees that the Administrative Agent has no obligation to ascertain the identity of the Borrower or any subsidiary or any authorized signatories of such person, on behalf of any Lender, or to confirm the completeness or accuracy of any information it obtains from any such person or any such authorized signatory in doing so.

(21) Merger, etc. In the event that any MDA Party or MDA Pledgor shall merge, consolidate or amalgamate with or into, or sell, convey, transfer, lease or otherwise dispose of (in one transaction or a series of transactions) all or substantially all of its assets to, any other person, the Borrower shall:

(23) Most Favoured Lender. The Borrower covenants and agrees that if at any time any Credit Document (as defined below) shall include any financial requirement or condition pertaining to any MDA Party and/or any MDA Pledgor (however expressed and whether stated as a covenant, event of default or otherwise), which is not included in this agreement or which is more restrictive than any comparable provision included in this agreement (a “Most Favoured Provision”), then (i) such Most Favoured Provision shall immediately and automatically be incorporated by reference in this agreement as if set forth fully herein, mutatis mutandis, (ii) the Borrower shall promptly, and in any event within five days of such Most Favoured Provision becoming effective under any Credit Document, so advise the Administrative Agent in writing, providing with such notice a copy of the applicable Credit Document(s), (iii) thereafter, (A) so long as no Default or Event of Default shall then exist under or in respect of such incorporated Most Favoured Provision, then such Most Favoured Provision shall automatically (without any action being taken by the Borrower, the Administrative Agent or any Lender) cease to be incorporated in this agreement simultaneously with the termination of such Credit Document (in accordance with its terms and not in connection with a temporary waiver of rights thereunder), or (B) if a Default or Event of Default shall exist under or in respect of such incorporated Most Favoured Provision on such termination date, then such Most Favoured Provision shall continue in effect until such Default or Event of Default shall be cured or waived in accordance with the applicable provisions of this agreement, and (iv) such Most Favoured Provision shall automatically (without any further action being taken by the Borrower, the Administrative Agent or any Lender other than as set forth below) be further modified if such Most Favoured Provision is made more or less restrictive on any MDA Party and/or MDA Pledgor, as the case may be, by way of a permanent written amendment or modification of such Credit Document (and not by temporary waiver of rights thereunder); provided that (1) to the extent any consideration is paid or given to any lender or other creditor under any Credit Document in connection with any amendment or modification of any Most Favoured Provision, the Borrower shall pay or provide each Lender equivalent consideration, determined based upon the respective amounts of credit provided under this agreement and the Credit Document and on a pro rata basis, and (2) in no event shall any modification of any such Most Favoured Provision have the effect of making any change to any covenant or other provision operative under this agreement (other than as a result of the incorporation therein pursuant to this section 10.1(23).

(26) Further Assurances. It will at its cost and expense, upon request of the Administrative Agent or the Collateral Agent, duly execute and deliver, or cause to be duly executed and delivered, to the Administrative Agent (or, as the case may be, the Collateral Agent) such further instruments and do and cause to be done such further acts as may be necessary or proper in the reasonable opinion of the Administrative Agent (or, as the case may be, the Collateral Agent) to carry out more effectually the provisions and purposes of this agreement and the other Credit Facility Documents.

Article 11

CHANGES IN CIRCUMSTANCES

11.1 Illegality.

If the enactment of any applicable Law in any jurisdiction or any province, state, territory or other political subdivision thereof, or any change therein or in the interpretation or application thereof by any Official Body or compliance by a Lender with any guideline, official directive, request or direction (whether or not having the force of Law) of any Official Body in any jurisdiction or any province, state, territory or other political subdivision thereof, hereafter makes it unlawful for a Lender to make, fund or maintain any type of Accommodation or to give effect to its obligations in respect of such type of Accommodation, such Lender may, by written notice thereof to the Borrower and to the Administrative Agent, declare its obligations under this agreement in respect of such type of Accommodation to be terminated, whereupon the same shall forthwith terminate, and the Borrower shall within the time required by such Law (or at the end of such longer period as such Lender at its discretion has agreed) repay or effect a Conversion of the Principal Outstanding in respect of such type of Accommodation from such Lender, and shall pay all accrued interest and fees payable hereunder and all Increased Costs incurred in connection with the termination or Conversion of such type of Accommodation.

11.2 Circumstances Requiring Different Pricing.

If, on or before any date on which an interest rate or Discount Rate is to be determined on the basis of the CDOR Rate or US LIBOR, either:

(a) the Administrative Agent (acting reasonably) determines that, because of circumstances affecting the London interbank market, adequate and fair means do not exist for ascertaining US LIBOR with respect to, or deposits are not available in sufficient amounts in the ordinary course of business to fund, a requested US LIBOR Advance;

94

(b) the Administrative Agent (acting reasonably) determines that the making or continuing of the requested US LIBOR Advance by the Lenders has been made impracticable by the occurrence of an event which materially adversely affects the London interbank market generally;

(c) the Agent is advised by Lenders holding at least 25% of the Commitments of all Lenders hereunder by written notice, such notice received by the Administrative Agent no later than 2:00 p.m. (Toronto time) on the third Business Day prior to the date of the requested US LIBOR Advance that such Lenders have determined (acting reasonably) that US LIBOR will not adequately reflect the cost of funds to such Lenders of US Dollar deposits in such market for the relevant Interest Period;

(d) the Administrative Agent (acting reasonably) makes a determination, which determination shall be conclusive and binding upon the Borrower, and notifies the Borrower, that there no longer exists an active market for Bankers’ Acceptances accepted by the Lenders; or

(e) the Administrative Agent is advised by Lenders holding at least 25% of the Commitments of all Lenders hereunder by written notice that such Lenders have determined (acting reasonably) that the Discount Rate will not or does not accurately reflect the cost of funds of such Lenders or the discount rate which would be applicable to a sale of Bankers’ Acceptances accepted by such Lenders in the market;

then the Administrative Agent shall forthwith give notice of such event to the Borrower and each Lender, whereupon the obligation of each Lender to make CDOR Rate Advances, US LIBOR Advances or Drawings (as the case may be) to the Borrower shall be suspended until the Administrative Agent gives notice to the Borrower and the Lenders that the circumstances giving rise to such determination no longer exist.

11.3 Ibid.

If the Administrative Agent receives notice from a Lender that, by reason of circumstances affecting financial markets inside or outside Canada, such Lender is unable to fund US Dollar Advances in Canada, then:

(a) it shall so notify the Borrower and all Lenders and the right of the Borrower to select any affected type of Accommodation shall be suspended;

(b) if any affected type of Accommodation is not yet outstanding, any applicable Notice shall be cancelled insofar as it relates to that type of Accommodation and that type of Accommodation requested therein shall not be made in that form, without affecting the right of the Borrower to request another type of Accommodation; and

(c) if any affected type of Accommodation is already outstanding at any time when the right of the Borrower to select such type of Accommodation is suspended, it shall upon ten days’ notice to the Borrower become a Prime Rate Advance by Conversion (or on such earlier date as may be required to comply with applicable Law).

95

11.4 Increased Costs.

If:

(a) the enactment or amendment of any Law or any change in the interpretation or application thereof by any Official Body; or

(b) compliance by any Lender with any amendment or change to any existing directive, request or requirement (whether or not having the force of Law) of any Official Body (including the Bank for International Settlements’ Paper on Capital Convergence, as implemented in Canada by the Office of the Superintendent of Financial Institutions’ Release dated August 19, 1988 and any further or other document), or with any new such directive, request or requirement;

shall have the effect of:

(c) increasing the cost to such Lender of performing its obligations under this agreement or in respect of any Accommodation, including the costs of maintaining any capital, reserve or special deposit requirements with respect to this agreement or any Accommodation or with respect to its obligations hereunder or thereunder;

(d) requiring such Lender to maintain or allocate any capital (including a requirement affecting such Lender’s allocation of capital to its obligations) or additional capital in respect of its obligations under this agreement or in respect of any Accommodation or otherwise reducing the effective return to such Lender under this agreement or in respect of any Accommodation or on its total capital as a result of entering into this agreement or making any Accommodation;

(e) reducing any amount payable to it by or in an amount it deems material (other than a reduction resulting from a higher rate of income or capital Tax or other special Tax relating to such Lender’s income or capital in general); or

(f) causing such Lender to make any payment or to forgo any return on or calculated by reference to any amount received or receivable by such Lender under this agreement or in respect of any Accommodation;

such Lender may give notice to the Borrower (with a copy to the Administrative Agent) specifying the nature of the event giving rise to such additional cost, reduction, payment or forgone return and the Borrower shall promptly pay such amounts as such Lender may specify to be necessary to compensate it for any such additional cost, reduction, payment or forgone return. A certificate setting out, in reasonable detail, the amount of any such additional cost, reduction, payment or forgone return, submitted in good faith by such Lender to the Borrower, shall be conclusive and binding for all purposes absent demonstrated error.

If such circumstances continue in effect for 60 consecutive days, on request from the Borrower, the Borrower and the Administrative Agent shall use their reasonable best efforts to arrange for one or more other persons (in this section 11.4, the “assuming Lender”) reasonably satisfactory to the Borrower and the Administrative Agent to assume all or a portion of the relevant Commitments and acquire the outstanding Accommodations and other rights and interests of the affected Lender hereunder. The assuming Lender and affected Lender shall execute all such documents as may be reasonably required by the Administrative Agent and the Borrower to effect such assumption and acquisition. Failing such assumption and acquisition, the Borrower may effect a prepayment and cancellation of the relevant Commitments of the affected Lender (without reducing or prepaying the Commitment(s) of any other Lender(s)).

96

11.5 Indemnification.

(1) Matching Funds. The Borrower shall promptly pay to each Lender any amounts required to compensate such Lender or its Participants for any breakage or similar cost, loss, cost of redeploying funds or other cost or expense suffered or incurred by such Lender or Participant as a result of:

(a) any payment being made by the Borrower in respect of a US LIBOR Advance, CDOR Rate Advance or Bankers’ Acceptance (due to acceleration hereunder or a mandatory repayment or prepayment of principal or for any other reason) on a day other than the last day of an Interest Period or the maturity date applicable thereto; provided that, where the event giving rise to such payment is a mandatory repayment or prepayment, the Borrower may at its option instead deposit the amount of the repayment or prepayment to a segregated account pending expiry of the existing Interest Period or (as the case may be) maturity of outstanding Bankers Acceptances, and the monies in such segregated account shall be applied by the Administrative Agent to the required repayment or prepayment on the expiry of such Interest Period or maturity of such Bankers Acceptance;

(b) the Borrower’s failure to give notice in the manner and at the times required hereunder; or

(c) the failure of the Borrower to fulfil or honour, before the date specified for any Accommodation, the applicable conditions set forth in Article 6 or to accept an Accommodation after delivery of a Notice in the manner and at the time specified in such Notice.

A certificate of such Lender submitted to the Borrower (copy to the Administrative Agent) as to the amount necessary to so compensate such Lender or its Participants shall be conclusive evidence, absent demonstrated error, of the amount due from the Borrower to such Lender.

(2) General. Without limiting section 10.1(12), the Borrower agrees to indemnify the Administrative Agent, the Lenders and their respective affiliates, and the directors, officers and employees of each of them, from and against any and all liabilities, obligations, losses, damages, penalties, actions, judgments, suits, costs, expenses or disbursements of any kind or nature whatsoever which may be imposed on, incurred by, or asserted against the indemnitees or any of them, related to or arising out of the transactions contemplated hereunder or under any other Credit Facility Document; provided that no amount shall be payable under this section 11.5(2) to the extent that same arises out of the gross negligence or wilful misconduct of an indemnified person, or out of a breach by it of the terms of this agreement or any other Credit Facility Document.

11.6 Taxes, Costs, etc.

(1) Gross-Up. Any and all payments by the Borrower under this agreement or any other Credit Facility Document shall be made free and clear of and without deduction or withholding for Taxes unless such Taxes are required by Law to be deducted or withheld. If the Borrower shall be required by Law to deduct or withhold any Taxes from or in respect of any sum payable hereunder or thereunder:

(a) the sum payable shall be increased as may be necessary so that after making all required deductions or withholdings (including deductions or withholdings applicable to additional amounts paid under this section) the Administrative Agent or the relevant Lender (as the case may be) receives an amount equal to the sum it would have received if no deduction or withholding had been made;

97

(b) the Borrower shall make such deductions or withholdings; and

(c) the Borrower shall pay the full amount deducted or withheld to the relevant taxation or other authority in accordance with applicable Law.

Within 30 days after paying any sum from which it is required by Law to make any deduction or withholding, and within thirty days after the due date of payment of any Tax which it is required by section 11.6(1)(b) above to pay, the Borrower shall deliver to the Administrative Agent an official receipt or other evidence satisfactory to the other affected parties of such deduction, withholding or payment and of the remittance thereof to the relevant Official Body.

(2) Prepayment; Replacement. In the event that the Borrower shall become obligated to make additional payments to a Lender by virtue of this section 11.6, the Borrower shall be permitted to:

(a) effect a voluntary prepayment under section 2.4(2) of all (but not less than all) of the Obligations owed to such Lender under each relevant Credit Facility, without the obligation to effect concurrent prepayments to any other Lenders as contemplated by section 2.4(3); or

(b) as to the entire Commitment of such Lender under each relevant Credit Facility, replace such Lender with one or more existing Lenders or by a new Lender, in each case where such existing or new Lender is satisfactory to the Borrower, the Administrative Agent and the Fronting Lender.

(3) Pay Taxes. The Borrower shall pay all Taxes which arise from any payment made hereunder or under any other Credit Facility Document or from the execution, delivery or registration of, or otherwise with respect to, this agreement or such other Credit Facility Document.

(4) Indemnity. The Borrower shall indemnify and save harmless the Administrative Agent and each Lender for the full amount of Taxes (including any Taxes imposed by any jurisdiction on amounts payable under this section) paid by the Administrative Agent or such Lender (as the case may be) and any liability (including penalties, interest and expense) arising therefrom or with respect thereto, whether or not such Taxes were correctly or legally asserted. Payment under this indemnification shall be made within 30 days from the date the Administrative Agent or such Lender (as the case may be) makes written demand therefor. A certificate as to the amount of such Taxes submitted by the Administrative Agent or such Lender (as the case may be) to the Borrower (copy to the Administrative Agent if submitted by a Lender) shall be conclusive evidence, absent demonstrated error, of the amount due from the Borrower to Administrative Agent or such Lender (as the case may be).

(5) Survival. Without prejudice to the survival of any other agreement or obligation of the Borrower hereunder or under any other Credit Facility Document, the obligations of the Borrower under this section 11.6 shall survive the payment and performance of the Obligations.

(6) Limitation. The Administrative Agent or the relevant Lender (as the case may be) shall exercise reasonable commercial efforts to limit the incidence of any additional amounts payable under this section 11.6, and the Borrower shall not be obligated to pay any such amounts to the extent that they arise after the cause of same is rescinded, removed, repealed or withdrawn.

98

(7) FATCA. If a payment made to a Lender hereunder would be subject to United States federal withholding Taxes imposed by FATCA if such Lender were to fail to comply with the applicable reporting requirements of FATCA (including those contained in Section 1471(b) or 1472(b) of the Code, as applicable), such Lender shall deliver to the Borrower and the Administrative Agent, at the time or times prescribed by Law and at such time or times reasonably requested by the Borrower or the Administrative Agent, such documentation prescribed by applicable Law (including as prescribed by Section 1471(b)(3)(C)(i) of the Code) and such additional documentation reasonably requested by the Borrower or the Administrative Agent as may be necessary for the Borrower and the Administrative Agent to comply with their obligations under FATCA and to determine that such Lender has complied with such Lender’s obligations under FATCA or to determine the amount to deduct and withhold from such payment. Solely for purposes of this clause (7), “FATCA” shall include any amendments made to FATCA after the date of this agreement.

11.7 Affected Lender.

(1) Replacement of Affected Lender. If any Lender does not provide its consent or agreement to a request by the Borrower for a waiver, approval or amendment which requires the consent of all of the Lenders pursuant to the provisions of this agreement (each such non-consenting Lender being herein referred to as an “Affected Lender”), then the Borrower may, provided no Event of Default has occurred and is continuing, give the Administrative Agent notice of its intention to cause such Affected Lender to assign its Commitment in full to one or more financial institutions acceptable to the Administrative Agent, the Swingline Lender and the Fronting Lender, and the Borrower shall pay any fees payable thereunder in connection with such assignment; provided that, on the date of such assignment:

(a) such Affected Lender shall execute and deliver such documents assigning its Commitment as shall be required for such purpose, as contemplated by section 14.8;

(b) the replacement Lender shall pay to such Affected Lender an amount equal to the principal of, and all accrued interest on, all outstanding Accommodations of such Affected Lender; and

(c) the Borrower shall pay any amounts payable to such Affected Lender under section 11.5 as if it were a voluntary prepayment under section 2.4.

(2) Repayment of Affected Lender. In addition, in the circumstances set forth in section 11.7(1) the Borrower may at its option, instead of causing such Affected Lender to assign its Commitment as aforesaid and provided no Event of Default has occurred and is continuing, elect to prepay and permanently cancel the Commitment of such Affected Lender, in which case:

(a) the Borrower shall pay to such Affected Lender an amount equal to the principal of, and all accrued interest on, all outstanding Accommodations of such Affected Lender; and

(b) the Borrower shall pay any amounts payable to such Affected Lender under section 11.5 as if it were a voluntary prepayment under section 2.4.

99

(3) No Obligation. Neither the Administrative Agent nor any Lender shall be obligated to take up any Affected Lender’s Commitment or to locate or provide a replacement for any Affected Lender.

(4) More Than One Affected Lender. If, in any circumstances, there is more than one Affected Lender, the Borrower shall deal with each such Affected Lender in an equivalent manner.

(b) shall, at the request of the Majority Lenders, by notice to the Borrower declare the Obligations to be forthwith due and payable, without presentment, demand, protest or further notice of any kind, all of which are hereby expressly waived by the Borrower.

(2) Specific Defaults. If any Event of Default specified in section 12.1(7) or 12.1(8) shall occur, then all obligations of the Lenders in respect of the Commitments shall be automatically cancelled and the Obligations shall be forthwith due and payable, all as if the request and notice specified in each of sections 12.2(1)(a) and 12.2(1)(b) had been received and given by the Administrative Agent.

(3) Enforcement. Upon the occurrence of an Event of Default and acceleration of the Obligations, the Administrative Agent may, and shall at the request of the Majority Lenders, commence such legal action or proceedings as it may deem expedient, including exercising and enforcing its rights and remedies under any Security (subject to the Intercreditor Agreement), all without any additional notice, presentation, demand, protest, notice of dishonour, entering into of possession of any of the property or assets of any MDA Party or MDA Pledgor, or any other action, notice of all of which the Borrower hereby expressly waives. The rights and remedies of the Administrative Agent, the Lenders, the other Secured Parties and the Collateral Agent hereunder and under the other Credit Facility Documents are cumulative and are in addition to and not in substitution for any other rights or remedies provided by Law; provided that nothing herein contained shall permit any Lender to take any steps which, pursuant to this agreement, may only be undertaken by or with the consent of all Lenders or the Majority Lenders. Nothing contained herein or in any Security now or hereafter held by the Collateral Agent, with respect to the Collateral or any part thereof, nor any act or omission of the Collateral Agent, the Administrative Agent, any Lender or any other Secured Party with respect to such Security, shall in any way prejudice or affect the rights, remedies and powers of the Collateral Agent, the Administrative Agent, the Lenders or any other Secured Party with respect to any other such Security.

12.3 Right of Set-Off.

Following the occurrence of an Event of Default and a declaration under section 12.2(1)(b) or the Obligations becoming due and payable under section 12.2(2), each Lender is hereby authorized by the Borrower at any time and from time to time to the fullest extent permitted by Law to set off and apply any and all deposits (general or special, time or demand, provisional or final) at any time held and other Debt at any time owing to or for the credit or the account of the Borrower against any and all of the Obligations of the Borrower then due and payable hereunder and unpaid, and without limitation the Administrative Agent may debit any account of the Borrower for any such Obligations, whether owed to the Administrative Agent in its capacity as Administrative Agent or Lender or owed to other Lenders. Each Lender shall promptly notify the Borrower, the Administrative Agent and each other Lender after any such set-off and application made by such Lender; provided that the failure to give such notice shall not affect

103

the validity of such set-off and application. The rights of the Lenders under this section 12.3 are, as between themselves, subject to section 14.1, and the rights of the Administrative Agent and the Lenders under this section 12.3 are in addition to all other rights and remedies (including other rights of set-off) which the Administrative Agent or the Lenders may have.

12.4 Currency Conversion After Acceleration.

At any time following the occurrence of an Event of Default and the acceleration of the Obligations, each Lender shall be entitled to convert, with two Business Days’ prior notice to the Borrower, its unpaid and outstanding Canadian Dollar Advances under the Credit Facilities, or either of them, to Base Rate Advances. Any such conversion shall be calculated so that the resulting Base Rate Advances shall be the Equivalent Amount in US Dollars on the date of conversion of the amount of Canadian Dollars so converted. Any accrued and unpaid interest denominated in Canadian Dollars at the time of any such conversion shall be similarly converted to US Dollars, and such Base Rate Advances and accrued and unpaid interest thereon shall thereafter bear interest in accordance with Article 3.

Article 13

THE ADMINISTRATIVE AGENT AND THE LENDERS

13.1 Authorization and Action.

Each Lender hereby appoints and authorizes the Administrative Agent to take such action as agent on its behalf and to exercise such powers under this agreement and the other Credit Facility Documents as are delegated to the Administrative Agent by the terms hereof and thereof, together with such powers as are reasonably incidental thereto. As to any matters not expressly provided for by this agreement or such other Credit Facility Documents, the Administrative Agent shall not be required to exercise any discretion or take any action, but shall be required to act or to refrain from acting (and shall be fully indemnified and protected in so acting or refraining from acting) upon the instructions of the Majority Lenders and such instructions shall be binding upon all Lenders; provided that the Administrative Agent shall not be required to take any action which exposes it to personal liability or which is contrary to this agreement or such other Credit Facility Documents or applicable Law.

The Administrative Agent is hereby authorized and directed to enter into the Intercreditor Agreement in its capacity as Administrative Agent hereunder. Without limiting the immediately prior sentence, each Lender hereby authorizes the Administrative Agent to enter into the Intercreditor Agreement on behalf of such Lender (each Lender hereby agreeing to be bound by the terms of the Intercreditor Agreement as if it were a party thereto, with the Collateral Agent and the other Secured Parties being intended third-party beneficiaries of the authorization and agreement of this sentence).

Each Lender acknowledges that Royal Bank may also act as Collateral Agent, and hereby consents to Royal Bank doing so and the performance by Royal Bank of its duties and obligations as Collateral Agent under the Intercreditor Agreement. Each Lender further acknowledges that, in so acting, Royal Bank will be representing the interests of and acting as agent for all of the Secured Parties, and agrees that it will not claim or assert that, by entering into the Intercreditor Agreement as Collateral Agent or performing its duties and obligations thereunder, Royal Bank has breached any duty or obligation to such Lender or is subject to a conflict of interest.

13.2 Duties and Obligations.

The duties and obligations of the Administrative Agent hereunder shall be mechanical and administrative in nature, and the Administrative Agent shall not have by reason of this agreement or any other Credit Facility Document any fiduciary relationship or duty with or to any Lender.

104

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

(a) may treat any Lender as the payee of amounts attributable to such Lender’s Commitment unless and until the Administrative Agent receives written notice of the assignment thereof signed by such Lender and the Administrative Agent receives the written agreement of the assignee that such assignee is bound hereby as if it had been an original Lender party hereto, in each case in form satisfactory to the Administrative Agent and otherwise in accordance with section 14.8;

(b) may consult with legal counsel (including counsel for the Borrower), independent public accountants and other experts selected by it and shall not be liable to the Lenders 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;

(c) shall incur no liability under or in respect of this agreement or any other Credit Facility Document by acting upon any notice, consent, certificate or other instrument or writing (which may be by telegram, cable, facsimile or similar means of recorded communication) believed by it to be genuine and signed or sent by the proper party or parties or by acting upon any representation or warranty of the Borrower made or deemed to be made hereunder or thereunder;

(d) may assume that no Default or Event of Default has occurred and is continuing unless it has actual knowledge to the contrary; and

(e) may rely as to any matters of fact which might reasonably be expected to be within the knowledge of any person upon a certificate signed by or on behalf of such person.

Further, the Administrative Agent:

(f) makes no warranty or representation to any Lender and shall not be responsible to any Lender for the accuracy or completeness of the documents, information or financial data made available to the Lenders in connection with the negotiation of this agreement, or for any statements, warranties or representations (whether written or oral) made in or in connection with this agreement or any other Credit Facility Document;

(g) shall not have any duty to ascertain or to inquire as to the performance or observance of any of the terms, covenants or conditions of this agreement or any other Credit Facility Document on the part of any MDA Party or MDA Pledgor or any other person or to inspect any assets (including books and records); or

(h) shall not be responsible to any Lender for the due execution, legality, validity, enforceability, genuineness, sufficiency or value of this agreement or any other Credit Facility Document.

The Administrative Agent shall promptly distribute to the Lenders copies of all material received from the Borrower in compliance with the Borrower’s reporting obligations hereunder.

105

13.3 Administrative Agent and Affiliates.

With respect to its Commitment and Accommodations made and to be made by it, the Administrative Agent, which is also a Lender, shall have the same rights and powers under this agreement and every other Credit Facility Document as any other Lender and may exercise the same as though it were not an agent; and the terms “Lender” and “Lenders” shall, unless otherwise expressly indicated, include the Administrative Agent in its capacity as Lender. Each Lender (including the Administrative Agent) and its affiliates may accept deposits from, lend money to and generally engage in any kind of business with the Borrower and its affiliates, or any corporation or other entity owned or controlled by such persons, and any person which may do business with such persons, all as if it were not a party hereto and without any duty to account therefor to any Lender; provided that nothing in this section 13.3 shall affect in any manner whatsoever any covenant or other obligation on the part of the Borrower or any other person to be observed or performed under this agreement or any other Credit Facility Document.

13.4 Lender Credit Decision.

It is understood and agreed by each Lender that it has itself been, and will continue to be, solely responsible for making its own independent appraisal of and investigations into the financial condition, creditworthiness, condition, affairs, status and nature of the Borrower and its affiliates. Accordingly, each Lender confirms to the Administrative Agent and each other Lender that it has not relied, and will not hereafter rely, on the Administrative Agent or any other Lender:

(a) to check or inquire on its behalf into the adequacy, accuracy or completeness of any information provided by or on behalf of the Borrower or any affiliate under or in connection with this agreement or any other Credit Facility Document or the transactions herein or therein contemplated (whether or not such information has been or is hereafter distributed to such Lender by the Administrative Agent or another Lender), or

(b) to assess or keep under review on its behalf the financial condition, creditworthiness, condition, affairs, status or nature of the Borrower or any affiliate.

Each Lender acknowledges that a copy of this agreement has been made available to it for its review and that it is satisfied with the form and substance hereof.

13.5 Indemnifications.

Each Lender shall indemnify the Administrative Agent, each affiliate thereof, and each respective director, officer, and employee of the Administrative Agent and of each such affiliate (to the extent not indemnified by the Borrower), rateably with all other Lenders according to their respective Commitments, from and against any and all liabilities, obligations, losses, damages, penalties, actions, judgments, suits, costs, expenses or disbursements of any kind or nature whatsoever which may be imposed on, incurred by, or asserted against the Administrative Agent or any such affiliate, director, officer or employee in any way relating to or arising out of this agreement or any other Credit Facility Document or any action taken or omitted by the Administrative Agent or any such affiliate, director, officer or employee under this agreement or any other Credit Facility Document; provided that no Lender shall be liable for any portion of such liabilities, obligations, losses, damages, penalties, actions, judgments, suits, costs, expenses or disbursements resulting from the gross negligence or wilful misconduct of the indemnitee. Without limiting the generality of the foregoing, each Lender agrees to reimburse the Administrative Agent and each such affiliate, director, officer or employee promptly upon demand for its share (determined rateably as aforesaid) of any out-of-pocket expenses (including counsel fees) incurred by the indemnitee in connection with the preservation of any rights of the Administrative Agent or the Lenders under, or the enforcement of, or legal advice in respect of rights or responsibilities under, this agreement or any other Credit Facility Document, to the extent that the Administrative Agent or such affiliate, director, officer or employee is not reimbursed for such expenses by the Borrower.

106

13.6 Successor Administrative Agent.

The Administrative Agent may, as hereinafter provided, resign at any time by giving written notice thereof to the Lenders and the Borrower and may be removed at any time with cause by the Majority Lenders. Upon any such resignation or removal, the Lenders, after consultation with the Borrower if no Event of Default exists, shall have the right to appoint a successor Administrative Agent, which shall be a Lender. If no successor Administrative Agent shall have been so appointed by the Lenders and shall have accepted such appointment within 30 days after the retiring Administrative Agent’s giving of notice of resignation or the Lenders’ removal of the retiring Administrative Agent, then the retiring Administrative Agent shall on behalf of the Lenders forthwith designate a Lender (if such Lender shall have accepted such designation) the pro tem successor Administrative Agent, and such designated Lender shall act as Administrative Agent hereunder pending the appointment of its successor. Upon the acceptance of any appointment as Administrative Agent hereunder by a successor Administrative Agent, such successor Administrative Agent shall thereupon succeed to and become vested with all the rights, powers, privileges and duties of the retiring Administrative Agent, and the retiring Administrative Agent shall be discharged from any further duties and obligations under this agreement. After any retiring Administrative Agent’s resignation or removal hereunder as Administrative Agent, the provisions of this Article 13 shall enure to its benefit as to any actions taken or omitted to be taken by it while it was Administrative Agent under this agreement.

13.7 Sub-Agent or Co-Agent.

At any time or times, in order to comply with any legal requirement in any province, state or other jurisdiction, or to facilitate the taking by the Administrative Agent of any action provided for in any Credit Facility Document, the Administrative Agent may appoint one or more trust companies, chartered banks or other persons (any of whom may, but need not be, a Lender) to act either as co-agent or sub-agent, jointly with the Administrative Agent or as a separate agent or agents on behalf of the Lenders, with such powers and authorities as the Administrative Agent deems necessary for the effective operation of the provisions of any Credit Facility Document. In the discretion of the Administrative Agent, any instrument or agreement appointing any such co-agent or sub-agent may include provisions for the protection of such co-agent or sub-agent similar to but no broader than the provisions of this Article 13. Upon the appointment of any such co-agent or sub-agent by the Administrative Agent, all references in this agreement and in all other Credit Facility Documents to the Administrative Agent shall thereafter be construed as references to such co-agent or sub-agent to the extent necessary in order to give effect to its powers, authorities and obligations.

13.8 Assignment of Documents.

Upon the resignation or removal of the Administrative Agent pursuant to section 13.6, the Administrative Agent shall assign and transfer to the successor Administrative Agent all of its right, title and interest, as agent, in and to the Credit Facility Documents. The successor Administrative Agent shall ensure that all required notices, registrations and filings in connection with such assignment are given or made, as the case may be, and the Borrower shall reimburse the successor Administrative Agent for and in respect of all of its reasonable costs and expenses in connection therewith.

13.9 Collective Action of the Lenders.

Each of the Lenders hereby acknowledges that to the extent permitted by applicable Law, any collateral security and the remedies provided under the Credit Facility Documents to the Lenders are for the benefit of the Lenders collectively and acting together and not severally and further acknowledges that its rights hereunder and under any collateral security are to be exercised not severally, but by the Administrative Agent upon the decision of the Majority Lenders (or such other number or percentage of the Lenders or other Secured Parties as shall be expressly provided for in the Credit Facility Documents). Accordingly, notwithstanding any of the provisions contained herein or in any other Credit Facility Document, each of the Lenders hereby covenants and agrees that it shall not be entitled to take any action hereunder or thereunder including any declaration of default hereunder or thereunder but that any such action shall be

107

taken only by the Administrative Agent with the prior written agreement of the Majority Lenders (or such other number or percentage of the Lenders or other Secured Parties as shall be expressly provided for in the Credit Facility Documents). Each of the Lenders hereby further covenants and agrees that upon any such written agreement being given, it shall co-operate fully with the Administrative Agent to the extent requested by the Administrative Agent. Notwithstanding the foregoing, in the absence of instructions from the Lenders and where in the sole opinion of the Administrative Agent, acting reasonably and in good faith, the exigencies of the situation warrant such action, the Administrative Agent may without notice to or consent of the Lenders take such action on behalf of the Lenders as it deems appropriate or desirable in the interest of the Lenders.

13.10  No Other Duties, etc.

Anything herein to the contrary notwithstanding, none of the bookrunners, arrangers or holders of similar titles, if any, specified in this agreement shall have any powers, duties or responsibilities under this agreement or any of the other Credit Facility Documents, except in its capacity, as applicable, as Administrative Agent or a Lender hereunder.

Article 14

MISCELLANEOUS

14.1 Sharing of Payments; Records.

(1) The Fronting Lender. Upon the occurrence of an Event of Default, adjustments shall be made among the Revolving Lenders as set forth in this section 14.1(1).

(a) Unless the Fronting Lender and the Majority Lenders under the Revolving Facility agree otherwise, if an Event of Default occurs and either:

(i) a payment had previously been made by the Fronting Lender under a Letter of Credit without full reimbursement by the Borrower (whether or not such failure to reimburse was the basis for such Event of Default); or

(ii) a Letter of Credit is thereafter drawn upon which results in a payment by the Fronting Lender thereunder;

(each, in this section 14.1(1), an “LC Payment”, in the case of item (i) only to the extent not previously reimbursed by the Borrower to the Fronting Lender), then the Fronting Lender will promptly request the Administrative Agent on behalf of the Borrower (and for this purpose the Fronting Lender is irrevocably authorized by the Borrower to do so) for a Borrowing by way of an Advance in the relevant currency from the Revolving Lenders pursuant to Article 3 to reimburse the Fronting Lender for such LC Payment. The Revolving Lenders are irrevocably directed by the Borrower to make any Advance if so requested by the Fronting Lender and pay the proceeds thereof directly to the Administrative Agent for the account of the Fronting Lender. Each Revolving Lender unconditionally agrees to pay to the Administrative Agent for the account of the Fronting Lender such Revolving Lender’s Rateable Portion of each Advance requested by the Fronting Lender on behalf of the Borrower to repay LC Payments made by the Fronting Lender.

(b) Except as provided in section 14.1(1)(d), the obligations of each Revolving Lender under section 14.1(1)(a) are unconditional, shall not be subject to any qualification or exception whatsoever and shall be performed in accordance with the terms and conditions of this agreement under all circumstances including:

108

(i) any lack of validity or enforceability of the Borrower’s obligations;

(ii) the occurrence of any Default or Event of Default or the exercise of any rights by the Administrative Agent under Article 12; and

(iii) the absence of any demand for payment being made, any proof of claim being filed, any proceeding being commenced or any judgment being obtained by the Fronting Lender against the Borrower.

(c) If a Revolving Lender (a “Defaulting Lender”) fails to make payment on the due date therefor of any amount due from it for the account of the Fronting Lender pursuant to section 14.1(1)(a) (the balance thereof for the time being unpaid being referred to in this section 14.1(1)(c) as an “overdue amount”) then, until the Fronting Lender has received payment of that amount (plus interest as provided below) in full (and without in any way limiting the rights of the Fronting Lender in respect of such failure):

(i) the Fronting Lender shall be entitled to receive any payment which the Defaulting Lender would otherwise have been entitled to receive in respect of the Revolving Facility or otherwise in respect of any Credit Facility Document; and

(ii) the overdue amount shall bear interest payable by the Defaulting Lender to the Fronting Lender at the rate payable by the Borrower in respect of the Obligations which gave rise to such overdue amount.

(d) If for any reason an Advance may not be made pursuant to section 14.1(1)(a) to reimburse the Fronting Lender as contemplated thereby, then promptly upon receipt of notification of such fact from the Administrative Agent, each Revolving Lender shall deliver to the Administrative Agent for the account of the Fronting Lender in immediately available funds the purchase price for such Revolving Lender’s participation interest in the relevant unreimbursed LC Payments (including interest then accrued thereon and unpaid by the Borrower). Without duplication, each Revolving Lender shall, upon demand by the Fronting Lender made to the Administrative Agent, deliver to the Administrative Agent for the account of the Fronting Lender interest on such Revolving Lender’s Rateable Portion from the date of payment by the Fronting Lender of such unreimbursed LC Payments until the date of delivery of such funds to the Fronting Lender by such Revolving Lender at a rate per annum in accordance with the Administrative Agent’s usual banking practice for similar advances to financial institutions of like standing as such Lender but in no event greater than, as the case may be, the Prime Rate or the Base Rate. Such payment shall only, however, be made by the Revolving Lenders in the event and to the extent the Fronting Lender has not been reimbursed in full by the Borrower for interest on the amount of such unreimbursed LC Payments.

(e) The Fronting Lender shall, forthwith upon its receipt of any reimbursement (in whole or in part) by the Borrower for any unreimbursed LC Payments in relation to which other Revolving Lenders have purchased a participation interest pursuant to section 14.1(1)(d), or of any other amount from the Borrower or any other person in respect of such payment, transfer to each other Revolving Lender such other Revolving Lender’s Rateable Portion of such reimbursement or other amount. In the event that any receipt by the Fronting Lender of any reimbursement or other amount is found to have been a transfer in fraud of creditors or a preferential payment under any applicable insolvency legislation or is otherwise required to be returned, such Revolving Lender shall promptly return to the Fronting Lender any portion thereof previously transferred to it by the Fronting Lender, without interest to the extent that interest is not payable by the Fronting Lender in connection therewith.

109

(2) Sharing. If:

(a) any Lender shall receive any payment or reduction (whether voluntary, involuntary, through the exercise of any right of set-off pursuant to section 12.3 or at law or equity, or otherwise) of the Obligations owed to it under a Credit Facility (other than Increased Costs paid to it) in excess of its Rateable Portion of such payment or reduction;

(b) after acceleration of the Obligations, any Lender shall receive any payment or reduction (whether voluntary, involuntary, through the exercise of any right of set-off pursuant to section 12.3 or at law or equity, or otherwise) of a proportion of the Obligations owed to it (other than Increased Costs paid to it) in excess of the proportion received by any other Lender (with all determinations of proportions being made on the basis of Obligations expressed as the Equivalent Amount of US Dollars); or

(c) (without regard to outstanding Increased Costs) any Lender shall at the time of acceleration of the Obligations have outstanding Obligations which are less than its Rateable Portion of all outstanding Obligations;

then such Lender shall forthwith purchase from the other Lenders such participations in the Accommodations made by such other Lenders as shall be necessary to cause such purchasing Lender to share the excess payment or reduction, or be owed such outstanding Obligations, rateably with such other Lenders.

In the case of paragraph (a) above, if all or any portion of such excess payment or reduction is thereafter recovered from such purchasing Lender, such purchase from each other Lender shall be rescinded and each Lender shall repay to the purchasing Lender the purchase price to the extent of such recovery together with an amount equal to such other Lender’s rateable share (according to the proportion that the amount such other Lender’s required repayment bears to the total amount so recovered from the purchasing Lender) of any interest or other amount paid or payable by the purchasing Lender in respect of the total amount so recovered.

Any Lender purchasing a participation from another Lender pursuant to this section 14.1 may, to the fullest extent permitted by Law, exercise all its rights of payment (including the right of set-off) with respect to such participation as fully as if such Lender were a direct creditor of the Borrower in the amount of such participation.

(3) Records. The Principal Outstanding and/or the US$ Equivalent Principal Outstanding under a Credit Facility, the unpaid interest accrued thereon, the interest rate or rates applicable to any unpaid principal amounts, the duration of such application, the date of acceptance or issue, Face Amount and maturity of all Bankers’ Acceptances and Letters of Credit and the Commitments shall at all times be ascertained from the records of the Administrative Agent, which shall be conclusive absent demonstrated error.

14.2 Amendments, etc.

(1) Amendments – General. Subject to section 14.2(2), no amendment or waiver of any provision of this agreement or of any other Credit Facility Document, nor any consent to any departure by the Borrower or any affiliate herefrom or therefrom, shall in any event be effective unless the same shall be in writing and signed by the Majority Lenders (or by the Administrative Agent on their authorization), and then such waiver or consent shall be effective only in the specific instance and for the specific purpose for which given.

110

(2) Amendments – Unanimous. No amendment, waiver or consent shall, unless in writing and signed by all the Lenders (or by the Administrative Agent on their authorization):

(b) reduce the principal amount of any Accommodation (including any amount owed to Lenders under section 5.7(1)) or reduce the rate of interest or any fee applicable to any Accommodation;

(c) postpone the scheduled date of payment of the principal amount of any Accommodation (including any amount owed to Lenders under section 5.7(1)), or any interest thereon or any fees payable in respect thereof, or waive or excuse any such payment;

(d) waive any of the conditions specified in Article 6;

(e) amend this section 14.2;

(i) except as set forth in section 8.8(1), release (or agree, consent to or approve the release of) all or substantially all of the Security; or

(j) amend the Intercreditor Agreement.

(3) Amendments – Administrative Agent. No amendment, waiver or consent shall, unless in writing and signed by the Administrative Agent (in addition to the Majority Lenders, if so required hereunder), affect the rights or duties of the Administrative Agent under any Credit Facility Document.

(4) Amendments – Fronting Lender. No amendment, waiver or consent shall, unless in writing and signed by the Fronting Lender (in addition to the Majority Lenders, if so required hereunder), affect the rights or duties of the Fronting Lender under any Credit Facility Document.

111

(b) An amendment, waiver or consent that affects only the rights or obligations of the Lenders under a particular Credit Facility, and does not affect the rights and obligations of the Lenders under the other Credit Facility, need only be approved by the Majority Lenders under such Credit Facility (or, if the circumstances contemplated by section 14.2(2) apply, by all of the Lenders under such Credit Facility).

14.3 Notices, etc.

14.4 No Waiver; Remedies.

No failure on the part of the Administrative Agent or any of the Lenders to exercise, and no delay in exercising, any right under any Credit Facility Document shall operate as a waiver thereof, nor shall any single or partial exercise of any right under any Credit Facility Document preclude any other or further exercise thereof or the exercise of any other right. The remedies herein and therein provided are cumulative and not exclusive of any remedies provided by Law.

14.5 Expenses.

The Borrower shall pay to the Administrative Agent, on its own account and on behalf of the Lenders, all reasonable costs and expenses (including all reasonable legal fees and disbursements on a solicitor and his own client basis) incurred:

(a) by the Administrative Agent in connection with this agreement, the other Credit Facility Documents and the Credit Facilities, including:

(i) the negotiation of the term sheet and the negotiation, preparation, printing, execution, delivery, syndication and interpretation, both prior and subsequent to the Closing Date, of this agreement and any other Credit Facility Document (in this section 14.5, collectively, the “Documents”);

(ii) the performance by the Administrative Agent of its obligations and duties under any Document;

(iii) advice of counsel with respect to the administration of or other matters relating to the Credit Facilities, any Document or any transaction contemplated thereunder;

(iv) the enforcement of any Document or the enforcement or preservation of rights under and the refinancing, renegotiation or restructuring (including negotiation of any so-called “workout” or similar transaction) of the Credit Facility under this agreement or any other Document or the bringing of any action, suit or proceeding with respect to the enforcement of any Document or any such right or seeking any remedy which may be available to the Administrative Agent or the Lenders at law or in equity; and

(v) any amendments, waivers or consents (including extensions) requested by or in respect of the Borrower or any affiliate pursuant to the provisions hereof or any other Document;

(b) by each of the Lenders in connection with:

114

(i) the enforcement of any Document or the enforcement or preservation of rights under and the refinancing, renegotiation or restructuring (including negotiation of any so-called “workout” or similar transaction) of the Credit Facilities under this agreement or any other Document or the bringing of any action, suit or proceeding with respect to the enforcement of any Document or any such right or seeking any remedy which may be available to the Lenders at law or in equity; and

(ii) any amendments, waivers or consents (including extensions) requested by or in respect of the Borrower or any affiliate pursuant to the provisions hereof or any other Document.

In addition, the Borrower shall pay any present or future stamp, documentary or other like duties and taxes or any other excise or property taxes, charges or similar levies which arise from any payment made under any Credit Facility Document or from the execution, delivery or registration of, or otherwise in respect to, any Credit Facility Document and shall indemnify and save the Administrative Agent and the Lenders harmless from and against any and all liabilities with respect to or resulting from any delay in paying or omission to pay such duties or taxes. The obligations of the Borrower under this section 14.5 shall survive the payment and performance of the Obligations.

14.6 Judgment Currency.

(1) Exchange Rate. If, for the purposes of obtaining judgment in any court, it is necessary to convert a sum due hereunder to the Administrative Agent or a Lender in one currency (in this section 14.6, the “Original Currency”) into another currency (in this section 14.6, the “Judgment Currency”), the parties agree, to the fullest extent that they may effectively do so, that the rate of exchange used shall be that at which in accordance with normal banking procedures the Administrative Agent or Lender could purchase the Original Currency with the Judgment Currency on the Business Day preceding that on which final judgment is paid or satisfied.

(2) Obligation. The obligations of the Borrower in respect of any sum due in the Original Currency from it to the Administrative Agent or a Lender under any Credit Facility Document shall, notwithstanding any judgment in any Judgment Currency, be discharged only to the extent that, on the Business Day following receipt by the Administrative Agent or Lender of any sum adjudged to be so due in such Judgment Currency, the Administrative Agent or Lender may in accordance with normal banking procedures purchase the Original Currency with such Judgment Currency. If the amount of the Original Currency so purchased is less than the sum originally due to the Administrative Agent or Lender in the Original Currency, the Borrower agrees, as a separate obligation and notwithstanding any such judgment, to indemnify the Administrative Agent or Lender against such loss and, if the amount of the Original Currency so purchased exceeds the sum originally due to the Administrative Agent or Lender in the Original Currency, the Administrative Agent or Lender agrees to remit such excess to the Borrower.

14.7 Governing Law.

(1) Governing Law. This agreement shall be governed by and construed in accordance with the Laws of the Province of British Columbia and the Laws of Canada applicable therein.

(2) Submission to Jurisdiction. Each party hereby irrevocably submits to the jurisdiction of the courts of British Columbia in any action or proceeding arising out of or relating to this agreement and hereby irrevocably agrees that all claims in respect of any such action or proceeding may be heard and determined in such courts. Each party hereby irrevocably waives, to the fullest extent it may effectively do so, the defence of an inconvenient forum to the maintenance of such action or proceeding. When a name and address is so

115

indicated opposite a party on the signature pages hereof, such party hereby irrevocably appoints the person of such name (in this section 14.7(2), its “Process Agent”) as its agent to receive on behalf of such party and its property service of copies of the summons and complaint and any other process which may be served in any such action or proceeding. Such service may be made by delivering a copy of such process to the party in care of its Process Agent at such Process Agent’s address so indicated, and such party hereby irrevocably authorizes and directs its Process Agent to accept such service on its behalf. As an alternative method of service, each party also irrevocably consents to the service of any and all process in any such action or proceeding by the mailing of copies of such process to it at its address referred to in section 14.3 or at such other address as it may direct in accordance with section 14.3. Each party agrees that a final judgment in any such action or proceeding shall be conclusive and may be enforced in other jurisdictions by suit on the judgment or in any other manner provided by Law.

(3) Non-Exclusive. Nothing in this section 14.7 shall affect the right of any party to serve legal process in any other manner permitted by Law or affect the right of a party to bring any action or proceeding against another party or its property in the courts of other jurisdictions.

(4) Trial by Jury. Each of the parties hereto, to the fullest extent permitted by Law, hereby waives its rights to a trial by jury.

14.8 Successors and Assigns.

(1) Effectiveness. This agreement shall become effective when it shall have been executed by the Borrower, the Administrative Agent and each Lender and thereafter shall be binding upon and enure to the benefit of each such person, its successors and permitted assigns.

(2) Borrower not to Assign. The Borrower shall not have the right to assign its rights or obligations hereunder or any interest herein (other than in compliance with section 10.2(3), without the prior consent of all the Lenders, which consent may be arbitrarily withheld.

(3) Participations. A Lender may grant participations in all or any part of a Credit Facility to one or more persons (each a “Participant”), and each Participant shall be entitled to the benefits of sections 11.4, 11.5 and 11.6, inclusive, to the same extent as if it were a Lender and had acquired its interest by assignment pursuant to section 14.8(4); provided that a Participant shall not be entitled to receive any greater payment under section 11.4 or 11.6 than the applicable Lender would have been entitled to receive with respect to the participation sold to such Participant, unless:

(a) the sale of the participation to such Participant is made with the Borrower’s prior written consent; or

(b) such entitlement to a greater payment results from a Change in Law occurring after the date such Participant became a participant.

For greater certainty, the Administrative Agent shall not be party to, receive notice of, consent to or otherwise be involved in any manner with participations, and shall not maintain any record of participations.

(4) Assignments. A Lender may assign all or any part (in a minimum amount of the lesser of (i) US$5 million, and (ii) such Lender’s remaining Commitments under the relevant Credit Facility) of its interest in either or both Credit Facilities to one or more persons (each an “Assignee”) and, to the extent of any such assignment (unless otherwise stated therein), the assignee shall have the same rights and benefits hereunder and under the other Credit Facility Documents as it would have if it were a Lender hereunder; provided that:

116

(a) unless:

(i) an Event of Default shall have occurred and be continuing; or

(ii) such assignment shall be to an affiliate of the assignor Lender, another Lender or an affiliate of another Lender;

the consent of the Borrower to an assignment under this section 14.8(4) shall be required (which consent shall not be unreasonably withheld, it being acknowledged that the Borrower may reasonably object to an assignment if the result thereof would be to subject the Borrower to an obligation to pay additional Increased Costs), and the Borrower shall have the right to request a period of 30 days within which to seek an alternate Assignee;

(b) the consent of the Administrative Agent, the Swingline Lender and the Fronting Lender to an assignment under this section 14.8(4) shall be required (which consent shall not be unreasonably withheld); and

(c) no Lender shall have an aggregate Commitment under both Credit Facilities below US$10 million as a result of an assignment by or to such Lender.

(5) Financial Information. A Lender may deliver a copy of any financial statement or any other information relating to the business, assets or condition (financial or otherwise) of the Borrower or its affiliates which may be furnished to it under this agreement or otherwise to any Participant or Assignee or any prospective Participant or Assignee to the extent reasonably required by such Participant or Assignee in connection with its interest or the proposed acquisition of an interest in a Credit Facility, subject to compliance by such Lender with section 14.10.

(6) Lender to Act. Prior to the occurrence of a Default or an Event of Default, the relevant Lender shall act on behalf of all of its Participants in all dealings with the Borrower in respect of each Credit Facility.

(7) Assumption. In order to effect an assignment contemplated by section 14.8(4), the relevant Lender (i) shall deliver to the Borrower (at such Lender’s cost but exclusive of the fees of the Borrower’s counsel) an agreement by which the Assignee assumes the obligations and agrees to be bound by all the terms and conditions of this agreement, all as if such Assignee had been an original party hereto, and (ii) shall pay an administration fee of US$3,500 to the Administrative Agent. Upon any such assignment and such assumption of the obligations of such Lender by such Assignee, such Lender and the Borrower shall be mutually released from their respective obligations hereunder to the extent of such assignment and assumption and shall thenceforth have no liability or obligations to each other to such extent, except in respect of actions taken or matters which have arisen prior to such assignment.

14.9 Conflict.

In the event of a conflict between the provisions of this agreement and the provisions of any other Credit Facility Document, the provisions of this agreement shall prevail.

117

14.10  Confidentiality.

Information provided by the Borrower hereunder will not be disclosed by the Administrative Agent or any Lender or used by the Administrative Agent or such Lender for any purpose other than evaluation, monitoring and review pursuant to this agreement; provided that such information may be disclosed:

(b) to any director, officer or employee of the Administrative Agent or Lender or its affiliates (for purposes related to this agreement); provided that same is treated in the same manner as other confidential information held by the Administrative Agent or Lender;

(c) to legal counsel, accountants and other consultants and professional advisors determined by the Administrative Agent or Lender to require such information for the purpose of assisting in or advising upon such evaluation, monitoring and review, if such persons are advised that such information is confidential to the Borrower;

(e) to the extent that such information is public;

(f) to the extent that such information was previously known to the Administrative Agent or Lender through means other than the Borrower, or was acquired from a third party not known to the Administrative Agent or Lender to be under a duty of confidentiality to the Borrower or its relevant affiliate; or

(g) with the written consent of the Borrower.

The Finance Parties acknowledge that the Borrower and/or its subsidiaries perform, or may from time to time perform, classified contracts funded by or for the benefit of the United States Federal Government and the Borrower and/or its subsidiaries possess or may possess information and items controlled under United States export control Laws and regulations and other national security regulations.

The Finance Parties agree that, in connection with any exercise of a right or remedy under the Credit Facility Documents, the United States Federal Government may remove classified information, export-controlled information, or government-issued materials prior to the implementation of any such remedial action implicating such classified information, export-controlled information, or government-issued materials, or that the parties may take other steps to acquire authorization, licenses or other arrangements to receive such information in accordance with United States laws and regulations.

118
