The Notes shall be substantially in the form set out in Exhibit 1-A, Exhibit 1-B and Exhibit 1-C, with such changes therefrom, if any, as may be approved by you and the Company. Certain capitalized terms used in this Agreement are defined in Schedule B; and references to a “Section,” “Schedule” or an “Exhibit” are, unless otherwise specified, to a Section of, or a Schedule or an Exhibit attached to, this Agreement.

Section 2. Sale and Purchase of Notes.

Section 2.1. Sale and Purchase of Notes. Subject to the terms and conditions of this Agreement, the Company will issue and sell to you and you will purchase from the Company, at the Closing provided for in Section 3, Notes in the principal amount and of the series specified opposite your name in Schedule A at the purchase price of 100% of the principal amount thereof. Contemporaneously with entering into this Agreement, the Company is entering into separate Note Purchase Agreements (the “Other Agreements”) identical with this Agreement with each of the other purchasers named in Schedule A (the “Other Purchasers”), providing for the sale at such Closing to each of the Other Purchasers of Notes in the principal amount and of the series specified opposite its name in Schedule A. Your obligation hereunder, and the obligations of the Other Purchasers under the Other Agreements, are several and not joint obligations, and you shall have no obligation under any Other Agreement and no liability to any Person for the performance or nonperformance by any Other Purchaser thereunder.

Section 2.2. Subsidiary Guaranty. Payment by the Company of all amounts due with respect to the Notes shall be absolutely and unconditionally guaranteed by the Subsidiary Guarantors pursuant to a guaranty and subordination agreement dated as of the date hereof substantially in the form attached to this Agreement as Exhibit 2.2 (the “Subsidiary Guaranty”) in favor of the holders of the Notes.

Section 2.3. Subordination Agreements. Pursuant to Section 9.11, each Subsidiary (other than a Subsidiary Guarantor) of the Company, if any, (i) which is owed Debt by the Company, a Restricted Subsidiary or any Subsidiary Guarantor and (ii) which has entered into a subordination agreement relating to the Bank Facility, the Existing Notes or the Additional Notes, shall enter into a subordination agreement substantially in the form attached to this Agreement as Exhibit 2.3 (individually, a “Subordination Agreement,” and, collectively the “Subordination Agreements”) pursuant to which each of such Subsidiaries will subordinate its right to receive payments of Debt, interest accrued thereon and premium, if any, and all other sums which may from time to time be due and owing to it from the Company, the Subsidiary Guarantors or any other Restricted Subsidiary of the Company to the prior payment in full in cash of the Notes, all upon the terms and conditions set forth in the Subordination Agreements.

Section 2.4. Release. (a) The holders of the Notes acknowledge and agree that any Subsidiary Guarantor (any of the foregoing a “Guarantor”) shall be deemed automatically discharged and released from the Note Documents to which it is a party pursuant to the written request of the Company, provided that (i) such Guarantor has been released and discharged, or is being simultaneously released and discharged, as an obligor and guarantor under and in respect of all Debt of the Company under the Bank Facility, the Existing Notes and any Additional Notes and the Company so certifies to the holders of the Notes in a certificate which accompanies such request for release and discharge, (ii) any such release and discharge shall be expressly conditioned upon receipt by the holders of the Notes of a written agreement executed by the Guarantor to be released pursuant to which such Guarantor shall agree that if, for any reason whatsoever, it thereafter becomes an obligor or guarantor under and in respect of any Debt of the Company under the Bank Facility, the Existing Notes or any Additional Notes, then such Guarantor shall contemporaneously provide written notice thereof to the holders of the Notes accompanied by a Subsidiary Guaranty of such Guarantor, (iii) at the time of such release and discharge, the Company shall deliver a certificate of a Responsible Officer to the holders of the Notes to the effect that no Default or Event of Default exists and (iv) such Guarantor shall be designated an Unrestricted Subsidiary in accordance and in compliance with the terms of Section 10.8.

Section 5.1. Organization; Power and Authority. The Company is a corporation duly organized, validly existing and in good standing under the laws of its jurisdiction of incorporation, and is duly qualified as an extra-provincial or a foreign corporation and is in good standing in each jurisdiction in which such qualification is required by law, other than those jurisdictions as to which the failure to be so qualified or in good standing could not, individually or in the aggregate, reasonably be expected to have a Material Adverse Effect. The Company has the corporate power and authority to own or hold under lease the properties it purports to own or hold under lease, to transact the business it transacts and proposes to transact, to execute and deliver this Agreement, the Other Agreements and the Notes and to perform the provisions hereof and thereof. The Company is subject to the relevant commercial law and civil law and is generally subject to suit and it is not, nor does any of its properties or revenues, enjoy any right of immunity from any judicial proceedings, including attachment prior to judgment, attachment in aid of execution, execution of the judgment or otherwise. The Company represents that the execution and delivery of this Agreement, the Other Agreements and the Notes constitute private and commercial acts rather than governmental or public acts of the Company.

-6-

Section 5.2. Authorization, Etc. This Agreement, the Other Agreements and the Notes have been duly authorized by all necessary corporate action on the part of the Company, and this Agreement constitutes, and upon execution and delivery thereof each Note will constitute, a legal, valid and binding obligation of the Company enforceable against the Company in accordance with its terms, except as such enforceability may be limited by (a) applicable bankruptcy, insolvency, reorganization, moratorium or other similar laws affecting the enforcement of creditors’ rights generally and (b) general principles of equity (regardless of whether such enforceability is considered in a proceeding in equity or at law).

Section 5.3. Disclosure. The Company, through its agent, Citigroup Global Markets, Inc., has delivered to you and each Other Purchaser a copy of a Confidential Offering Memorandum dated March 2012 (the “Memorandum”), relating to the transactions contemplated hereby. The Memorandum fairly describes, in all material respects, the general nature of the business and principal properties of the Company and its Subsidiaries as of the date hereof. Except as disclosed in Schedule 5.3, this Agreement, the Memorandum, the documents, certificates or other writings delivered to you by or on behalf of the Company in connection with the transactions contemplated hereby and the financial statements listed in Schedule 5.5 (this Agreement, the Other Agreements, the Notes, the Subsidiary Guaranty, the Memorandum and such documents, certificates or other writings and financial statements delivered to you and the Other Purchasers prior to March 30, 2012 being referred to collectively as the “Disclosure Documents”), taken as a whole, do not contain any untrue statement of a material fact or omit to state any material fact necessary to make the statements therein not misleading in light of the circumstances under which they were made. Except as disclosed in the Disclosure Documents, since December 31, 2011,there has been no change in the financial condition, operations, business, properties or prospects of the Company or any Restricted Subsidiary except changes that individually or in the aggregate could not reasonably be expected to have a Material Adverse Effect. There is no fact known to the Company that could reasonably be expected to have a Material Adverse Effect that has not been set forth herein or in the Disclosure Documents.

Section 5.4. Organization and Ownership of Shares of Subsidiaries; Affiliates. (a) Schedule 5.4 contains (except as noted therein) complete and correct lists of (i) the Company’s Subsidiaries, showing, as to each Subsidiary, the correct name thereof, the jurisdiction of its organization and the percentage of shares of each class of its capital stock or similar equity interests outstanding owned by the Company and each other Subsidiary, (ii) of the Company’s Affiliates, other than its Subsidiaries, (iii) the Subsidiary Guarantors and Restricted Subsidiaries of the Company and (iv) the Company’s directors and senior officers.

(b) All of the outstanding shares of capital stock or similar equity interests of each Subsidiary shown in Schedule 5.4 as being owned by the Company and its Subsidiaries have been validly issued, are fully paid and non-assessable and are owned by the Company or another Subsidiary free and clear of any Lien (except as otherwise disclosed in Schedule 5.4).

(c) Each Subsidiary or Affiliate identified in Schedule 5.4 is a corporation, unlimited liability company, trust, partnership or other legal entity duly organized, validly existing and in good standing under the laws of its jurisdiction of organization, and is duly qualified as an extra-provincial or a foreign corporation or other legal entity and is in good standing in each jurisdiction in which such qualification is required by law, other than those jurisdictions as to which the failure to be so qualified or in good standing could not, individually or in the aggregate, reasonably be expected to have a Material Adverse Effect. Each such Subsidiary has the corporate or other power and authority to own or hold under lease the properties it purports to own or hold under lease and to transact the business it transacts and proposes to transact.

(d) Except pursuant to the Bank Facility, the senior notes previously issued or assumed by the Company and the subordination agreements and guaranties related to each of the foregoing, all as described in Schedule 5.15, no Restricted Subsidiary is a party to, or otherwise subject to, any legal restriction or any agreement (other than this Agreement and customary limitations imposed by corporate law or legally equivalent statutes) restricting the ability of such Restricted Subsidiary to pay dividends out of profits or make any other similar distributions of profits to the Company or any of the Restricted Subsidiaries that owns outstanding shares of capital stock or similar equity interests of such Restricted Subsidiary.

Section 5.5. Financial Statements; Material Liabilities. The Company has delivered to each Purchaser copies of the financial statements of the Company listed on Schedule 5.5. All of said financial statements (including in each case the related schedules and notes) fairly present in all material respects the consolidated financial position of the Company and its consolidated Subsidiaries as of the respective dates specified in such financial statements and the Company’s consolidated results of operations and cash flows for the respective periods so specified and have been prepared in accordance with GAAP consistently applied throughout the periods involved except as set forth in the notes thereto (subject, in the case of any interim financial statements, to normal year-end adjustments). The Company and its Subsidiaries do not have any Material liabilities that are not disclosed on such financial statements or otherwise disclosed in the Disclosure Documents.

Section 5.6. Compliance with Laws, Other Instruments, Etc.

(b) Event of Default — a statement that such officer has reviewed the relevant terms hereof and has made, or caused to be made, under his or her supervision, a review of the transactions and conditions of the Company and the Restricted Subsidiaries from the beginning of the quarterly or annual period covered by the statements then being furnished to the date of the certificate and that such review shall not have disclosed the existence during such period of any condition or event that constitutes a Default or an Event of Default or, if any such condition or event existed or exists (including, without limitation, any such event or condition resulting from the failure of the Company or any Restricted Subsidiary to comply with any Environmental Law), specifying the nature and period of existence thereof and what action the Company shall have taken or proposes to take with respect thereto.

The Company shall not be required to disclose the following information pursuant to Section 7.1(c), 7.1(h) or 7.3:

Section 8.2. Optional Prepayments. The Company may, at its option, upon notice provided below, prepay at any time all, or from time to time any part of, any series of the Notes in an amount not less than 10% of the aggregate principal amount of the Notes of such series then outstanding, at 100% of the principal amount so prepaid, together with interest accrued thereon to the date of such prepayment, plus the Make-Whole Amount determined for the prepayment date with respect to such principal amount. The Company will give each holder of Notes of such series written notice of each optional prepayment under this Section 8.2 not less than 30 days and not more than 60 days prior to the date fixed for such prepayment. Each such notice shall specify such date (which shall be a Business Day), the aggregate principal amount of the Notes of such series to be prepaid on such date, the principal amount of each Note held by such holder to be prepaid (determined in accordance with Section 8.5), and the interest to be paid on the prepayment date with respect to such principal amount being prepaid, and shall also be accompanied by a certificate of a Senior Financial Officer as to the estimated Make-Whole Amount due in connection with such prepayment (calculated as if the date of such notice were the date of the prepayment), setting forth the details of such computation. Two Business Days prior to any prepayment pursuant to this Section 8.2, the Company shall deliver to each holder of Notes to be prepaid a certificate of a Senior Financial Officer specifying the calculation of such Make-Whole Amount as of the specified prepayment date.

Section 8.3. Designated Event.

(a) Notice of Designated Event. The Company will, within five Business Days after any Responsible Officer has knowledge of the occurrence of any Designated Event, give written notice of such Designated Event to each holder of Notes unless notice in respect of such Designated Event shall have been given pursuant to Section 8.3(b). If the Company for any reason whatsoever fails to comply with Section 10.11, it shall offer to prepay Notes as described in Section 8.3(c) and the offer shall be accompanied by the certificate described in Section 8.3(g).

-23-

(b) Condition to Company Action. The Company will not take any action that consummates or finalizes a Designated Event unless at least 15 days prior to such action it shall have given to each holder of Notes written notice of its intention to prepay the Bank Facility as a result thereof, describing such Designated Event and the amount of such payment.

(c) Offer to Prepay Notes. The offer to prepay Notes contemplated by Section 8.3(a) shall be an offer to prepay, in accordance with and subject to this Section 8.3, the Notes held by each holder (in this case only, “holder” in respect of any Note registered in the name of a nominee for a disclosed beneficial owner shall mean such beneficial owner) on a date specified in such offer (the “Proposed Prepayment Date”) on an equal basis with each of the Lenders which are being prepaid pursuant to the Bank Facility as a result of the occurrence of such Designated Event. If such Proposed Prepayment Date is in connection with an offer contemplated by Section 8.3(a), such date shall be not less than 15 days and not more than 20 days after the date of such offer (if the Proposed Prepayment Date shall not be specified in such offer, the Proposed Prepayment Date shall be the first Business Day after the 15th day after the date of such offer).

(d) Rejection. A holder of Notes may accept the offer to prepay made pursuant to this Section 8.3 by causing a notice of such acceptance to be delivered to the Company not later than 10 days after receipt by such holder of the most recent offer of prepayment. A failure by a holder of Notes to respond to an offer to prepay made pursuant to this Section 8.3 shall be deemed to constitute a rejection of such offer by such holder.

(e) Prepayment. Prepayment of the Notes to be prepaid pursuant to this Section 8.3 shall be at 100% of the principal amount of such Notes, together with interest on such Notes accrued to the date of prepayment, but without the Make-Whole Amount or any other premium. The prepayment shall be made on the Proposed Prepayment Date except as provided in Section 8.3(f).

(f) Deferral Pending Designated Event. The obligation of the Company to prepay Notes pursuant to the offers required by Section 8.3(c) and accepted in accordance with Section 8.3(d) is subject to the occurrence of the Designated Event in respect of which such offers and acceptances shall have been made. In the event that such Designated Event has not occurred on the Proposed Prepayment Date in respect thereof, the prepayment shall be deferred until, and shall be made on, the date on which such Designated Event occurs. The Company shall keep each holder of Notes reasonably and timely informed of (i) any such deferral of the date of prepayment, (ii) the date on which such Designated Event and the prepayment are expected to occur, and (iii) any determination by the Company that efforts to effect such Designated Event have ceased or been abandoned (in which case the offers and acceptances made pursuant to this Section 8.3 in respect of such Designated Event shall be deemed rescinded).

-24-

(g) Officer’s Certificate. Each offer to prepay the Notes pursuant to this Section 8.3 shall be accompanied by a certificate, executed by a Senior Financial Officer of the Company and dated the date of such offer, specifying: (i) the Proposed Prepayment Date; (ii) that such offer is made pursuant to this Section 8.3; (iii) the principal amount of each Note offered to be prepaid; (iv) the interest that would be due on each Note offered to be prepaid, accrued to the Proposed Prepayment Date; (v) that the conditions of this Section 8.3 have been fulfilled; and (vi) in reasonable detail, the nature and date or proposed date of the Designated Event.

Section 8.4. Prepayment for Tax Reasons. If at any time as a result of a Change in Tax Law (as defined below) the Company is or becomes obligated to make any Additional Payments (as defined below) in respect of any payment of interest on account of any of the Notes in an aggregate amount for all affected U.S. Dollar Notes or Canadian Notes equal to 5% or more of the aggregate amount of such interest payment on account of all of the U.S. Dollar Notes or Canadian Notes, as the case may be, the Company may give the holders of all affected Notes irrevocable written notice (each, a “Tax Prepayment Notice”) of the prepayment of such affected Notes on a specified prepayment date (which shall be a Business Day not less than 30 days nor more than 60 days after the date of such notice) and the circumstances giving rise to the obligation of the Company to make any Additional Payments and the amount thereof and stating that all of the affected Notes shall be prepaid on the date of such prepayment at 100% of the principal amount so prepaid together with interest accrued thereon to the date of such prepayment plus an amount equal to the Make-Whole Amount for each such Note, except in the case of an affected Note if the holder of such Note shall, by written notice given to the Company no more than 20 days after receipt of the Tax Prepayment Notice, reject such prepayment of such Note (each, a “Rejection Notice”). Such Tax Prepayment Notice shall be accompanied by a certificate of a Senior Financial Officer as to the estimated Make-Whole Amount due in connection with such prepayment (calculated as if the date of such notice were the date of the prepayment), setting forth the details of such computation. The form of Rejection Notice shall also accompany the Tax Prepayment Notice and shall state with respect to each Note covered thereby that execution and delivery thereof by the holder of such Note shall operate as a permanent waiver of such holder’s right to receive the Additional Payments arising as a result of the circumstances described in the Tax Prepayment Notice in respect of all future payments of interest on such Note (but not of such holder’s right to receive any Additional Payments that arise out of circumstances not described in the Tax Prepayment Notice or which exceed the amount of the Additional Payment described in the Tax Prepayment Notice), which waiver shall be binding upon all subsequent transferees of such Note. The Tax Prepayment Notice having been given as aforesaid to each holder of the affected Notes, the principal amount of such Notes together with interest accrued thereon to the date of such prepayment plus the Make-Whole Amount shall become due and payable on such prepayment date, except in the case of Notes the holders of which shall timely give a Rejection Notice as aforesaid. Two Business Days prior to such prepayment, the Company shall deliver to each holder of a Note being so prepaid a certificate of a Senior Financial Officer specifying the calculation of such Make-Whole Amount as of such prepayment date.

No prepayment of the Notes pursuant to this Section 8.4 shall affect the obligation of the Company to pay Additional Payments in respect of any payment made on or prior to the date of such prepayment. For purposes of this Section 8.4, any holder of more than one affected Note may act separately with respect to each affected Note so held (with the effect that a holder of more than one affected Note may accept such offer with respect to one or more affected Notes so held and reject such offer with respect to one or more other affected Notes so held).

-25-

The Company may not offer to prepay or prepay Notes pursuant to this Section 8.4 (a) if a Default or Event of Default then exists, (b) until the Company shall have taken commercially reasonable steps to mitigate the requirement to make the related Additional Payments or (c) if the obligation to make such Additional Payments directly results or resulted from actions taken by the Company or any Subsidiary (other than actions required to be taken under applicable law), and any Tax Prepayment Notice given pursuant to this Section 8.4 shall certify to the foregoing and describe such mitigation steps, if any.

For purposes of this Section 8.4: “Additional Payments” means additional amounts required to be paid to a holder of any Note pursuant to Section 13 by reason of a Change in Tax Law; and a “Change in Tax Law” means (individually or collectively with one or more prior changes) (i) an amendment to, or change in, any law, treaty, rule or regulation of Canada after the date of the Closing, or an amendment to, or change in, an official interpretation or application of such law, treaty, rule or regulation after the date of the Closing, which amendment or change is in force and continuing and meets the opinion and certification requirements described below or (ii) in the case of any other jurisdiction that becomes a Taxing Jurisdiction after the date of the Closing, an amendment to, or change in, any law, treaty, rule or regulation of such jurisdiction, or an amendment to, or change in, an official interpretation or application of such law, treaty, rule or regulation, in any case after such jurisdiction shall have become a Taxing Jurisdiction, which amendment or change is in force and continuing and meets such opinion and certification requirements. No such amendment or change shall constitute a Change in Tax Law unless the same would in the opinion of the Company (which shall be evidenced by an Officer’s Certificate of the Company and supported by a written opinion of counsel having recognized expertise in the field of taxation in the Taxing Jurisdiction, which for certainty includes Blake, Xxxxxxx & Xxxxxxx LLP in any appropriate jurisdiction, both of which shall be delivered to all holders of the Notes prior to or concurrently with the Tax Prepayment Notice in respect of such Change in Tax Law) affect the deduction or require the withholding of any Tax imposed by such Taxing Jurisdiction on any payment payable on the Notes.

Section 8.5. Allocation of Partial Prepayments. In the case of each partial prepayment of the Notes pursuant to Section 8.2, the principal amount of the Notes of a series to be prepaid shall be allocated pro rata among all of the holders of the Notes of such series at the time outstanding in proportion, as nearly as practicable, to the respective unpaid principal amounts thereof not theretofore called for prepayment. All prepayments pursuant to Section 8.3 or 8.4 shall be applied as therein provided.

Section 8.6. Maturity; Surrender, Etc. In the case of each prepayment of Notes pursuant to this Section 8, the principal amount of each Note to be prepaid shall mature and become due and payable on the date fixed for such prepayment (which shall be a Business Day), together with interest on such principal amount accrued to such date and the applicable Make-Whole Amount, if any. From and after such date, unless the Company shall fail to pay such principal amount when so due and payable, together with the interest and Make-Whole Amount, if any, as aforesaid, interest on such principal amount shall cease to accrue. Any Note paid or prepaid in full shall be surrendered to the Company and cancelled and shall not be reissued, and no Note shall be issued in lieu of any prepaid principal amount of any Note.

-26-

Section 8.7. Purchase of Notes. The Company will not and will not permit any Affiliate to purchase, redeem, prepay or otherwise acquire, directly or indirectly, any of the outstanding Notes of a series except (a) upon the payment or prepayment of the Notes of such series in accordance with the terms of this Agreement and the Notes of such series or (b) pursuant to an offer to purchase made by the Company or an Affiliate pro rata to the holders of all Notes of such series at the time outstanding upon the same terms and conditions. Any such offer shall provide each holder with sufficient information to enable it to make an informed decision with respect to such offer, and shall remain open for at least 15 Business Days. If the holders of more than 25% of the principal amount of the Notes of such series then outstanding accept such offer, the Company shall promptly notify the remaining holders of such fact and the expiration date for the acceptance by holders of Notes of such offer shall be extended by the number of days necessary to give each such remaining holder at least 10 Business Days from its receipt of such notice to accept such offer. The Company will promptly cancel all Notes acquired by it or any Affiliate pursuant to any payment, prepayment or purchase of Notes pursuant to any provision of this Agreement and no Notes may be issued in substitution or exchange for any such Notes.

Section 8.8. Make-Whole Amount.

(a) U.S. Dollar Notes. The term “Make-Whole Amount” means, with respect to any U.S. Dollar Note, an amount equal to the excess, if any, of the Discounted Value of the Remaining Scheduled Payments with respect to the Called Principal of such U.S. Dollar Note over the amount of such Called Principal; provided that the Make-Whole Amount may in no event be less than zero. For the purposes of determining the Make-Whole Amount, the following terms have the following meanings:

“Called Principal” means, with respect to any U.S. Dollar Note, the principal of such U.S. Dollar Note that is to be prepaid pursuant to Section 8.2 or 8.4 or has become or is declared to be immediately due and payable pursuant to Section 12.1, as the context requires.

“Discounted Value” means, with respect to the Called Principal of any U.S. Dollar Note, the amount obtained by discounting all Remaining Scheduled Payments with respect to such Called Principal from their respective scheduled due dates to the Settlement Date with respect to such Called Principal, in accordance with accepted financial practice and at a discount factor (applied on the same periodic basis as that on which interest on the Notes is payable) equal to the Reinvestment Yield with respect to such Called Principal.

-27-

“Reinvestment Yield” means, with respect to the Called Principal of any U.S. Dollar Note, (a) 0.50% in the case of any prepayment of the U.S. Dollar Notes pursuant to Section 8.2 or in the case of the acceleration of the U.S. Dollar Notes pursuant to Section 12.1 or (b) 0.75% in the case of any prepayment or payment of the U.S. Dollar Notes pursuant to Section 8.4 over, in each such case the yield to maturity implied by (i) the yields reported, as of 10:00 A.M. (New York City time) on the second Business Day preceding the Settlement Date with respect to such Called Principal, on the display designated as “Page PX1” (or such other display as may replace Page PX1) on the Bloomberg Financial Markets for the most recently issued actively traded on-the-run U.S. Treasury securities having a maturity equal to the Remaining Average Life of such Called Principal as of such Settlement Date, or (ii) if such yields are not reported as of such time or the yields reported as of such time are not ascertainable (including by way of interpolation), the Treasury Constant Maturity Series Yields reported, for the latest day for which such yields have been so reported as of the second Business Day preceding the Settlement Date with respect to such Called Principal, in Federal Reserve Statistical Release H.15 (or any comparable successor publication) for U.S. Treasury securities having a constant maturity equal to the Remaining Average Life of such Called Principal as of such Settlement Date.

In the case of each determination under clause (i) or (ii) as the case may be, of the preceding paragraph, such implied yield will be determined, if necessary, by (a) converting U.S. Treasury xxxx quotations to bond-equivalent yields in accordance with accepted financial practice and (b) interpolating linearly between (1) the applicable U.S. Treasury security with the maturity closest to and greater than such Remaining Average Life and (2) the applicable U.S. Treasury security with the maturity closest to and less than such Remaining Average Life. The Reinvestment Yield shall be rounded to the number of decimal places as it appears in the interest rate of the applicable U.S. Dollar Note.

“Remaining Average Life” means, with respect to any Called Principal, the number of years (calculated to the nearest one-twelfth year) obtained by dividing (a) such Called Principal into (b) the sum of the products obtained by multiplying (i) the principal component of each Remaining Scheduled Payment with respect to such Called Principal by (ii) the number of years (calculated to the nearest one-twelfth year) that will elapse between the Settlement Date with respect to such Called Principal and the scheduled due date of such Remaining Scheduled Payment.

“Remaining Scheduled Payments” means, with respect to the Called Principal of any U.S. Dollar Note, all payments of such Called Principal and interest thereon that would be due after the Settlement Date with respect to such Called Principal if no payment of such Called Principal were made prior to its scheduled due date; provided that if such Settlement Date is not a date on which interest payments are due to be made under the terms of the U.S. Dollar Notes, then the amount of the next succeeding scheduled interest payment will be reduced by the amount of interest accrued to such Settlement Date and required to be paid on such Settlement Date pursuant to Sections 8.2, 8.4 or 12.1.

“Settlement Date” means, with respect to the Called Principal of any U.S. Dollar Note, the date on which such Called Principal is to be prepaid pursuant to Section 8.2 or 8.4 or has become or is declared to be immediately due and payable pursuant to Section 12.1, as the context requires.

-28-

(b) Series A Notes. The term “Make-Whole Amount” means, with respect to any Series A Note, an amount equal to the excess, if any, of the Discounted Value of the Remaining Scheduled Payments with respect to the Called Principal of such Series A Note over the amount of such Called Principal; provided that the Make-Whole Amount may in no event be less than zero. For the purposes of determining the Make-Whole Amount, the following terms have the following meanings:

“Called Principal” means, with respect to any Series A Note, the principal of such Series A Note that is to be prepaid pursuant to Section 8.2 or has become or is declared to be immediately due and payable pursuant to Section 12.1, as the context requires.

“Discounted Value” means, with respect to the Called Principal of any Series A Note, the amount obtained by discounting all Remaining Scheduled Payments with respect to such Called Principal from their respective scheduled due dates to the Settlement Date with respect to such Called Principal, in accordance with accepted financial practice and at a discount factor (applied on the same periodic basis as that on which interest on the Notes is payable) equal to the Reinvestment Yield with respect to such Called Principal.

“Reinvestment Yield” means, with respect to the Called Principal of any Series A Note, 0.50% in the case of any prepayment of the Series A Notes pursuant to Section 8.2 or in the case of the acceleration of the Series A Notes pursuant to Section 12.1 over the yield to maturity as of the third Business Day preceding the Settlement Date with respect to such Called Principal, as provided by two major Canadian investment dealers designated by the holders of at least 51% in principal amount of the Series A Notes (the “Designated Investment Dealers”), for a non-callable Government of Canada bond in Canadian Dollars having a maturity equal to the Remaining Average Life of such Called Principal as of such Settlement Date, or (ii) if such yields are not reported as of such time or the yields reported as of such time are not ascertainable (including by way of interpolation) or if such yields are not agreed to by the Designated Investment Dealers, the average of the yields for such securities as determined by the Designated Investment Dealers.

In the case of each determination under the preceding paragraph, such implied yield will be determined, if necessary, by interpolating linearly between (1) the non-callable Government of Canada bond in Canadian Dollars with the maturity closest to and greater than the Remaining Average Life of such Called Principal and (2) the non callable Government of Canada bond in Canadian Dollars with the maturity closest to and less than the Remaining Average Life of such Called Principal. The Reinvestment Yield shall be rounded to the number of decimal places as appears in the interest rate of such Series A Note.

-29-

“Remaining Scheduled Payments” means, with respect to the Called Principal of any Series A Note, all payments of such Called Principal and interest thereon that would be due after the Settlement Date with respect to such Called Principal if no payment of such Called Principal were made prior to its scheduled due date; provided that if such Settlement Date is not a date on which interest payments are due to be made under the terms of the Series A Notes, then the amount of the next succeeding scheduled interest payment will be reduced by the amount of interest accrued to such Settlement Date and required to be paid on such Settlement Date pursuant to Section 8.2 or 12.1.

“Settlement Date” means, with respect to the Called Principal of any Series A Note, the date on which such Called Principal is to be prepaid pursuant to Section 8.2 or has become or is declared to be immediately due and payable pursuant to Section 12.1, as the context requires.

Section 8.9. Change in Control. (a) Notice of Change in Control. The Company will, within five Business Days after any Responsible Officer has knowledge of the occurrence of any Change in Control, give written notice of such Change in Control to each holder of Notes. Such notice shall contain and constitute an offer to prepay Notes as described in subparagraph (b) of this Section 8.9 and shall be accompanied by the certificate described in subparagraph (e) of this Section 8.9.

(b) Offer to Prepay Notes. The offer to prepay Notes contemplated by subparagraph (a) of this Section 8.9 shall be an offer to prepay, in accordance with and subject to this Section 8.9, all, but not less than all, the Notes held by each holder (in this case only, “holder” in respect of any Note registered in the name of a nominee for a disclosed beneficial owner shall mean such beneficial owner) on a date specified in such offer (the “Proposed Prepayment Date”). Such date shall be not less than 30 days and not more than 120 days after the date of such offer (if the Proposed Prepayment Date shall not be specified in such offer, the Proposed Prepayment Date shall be the first Business Day after the 45th day after the date of such offer).

(c) Acceptance/Rejection. A holder of Notes may accept the offer to prepay made pursuant to this Section 8.9 by causing a notice of such acceptance to be delivered to the Company not later than 15 days after receipt by such holder of the most recent offer of prepayment. A failure by a holder of Notes to respond to an offer to prepay made pursuant to this Section 8.9 shall be deemed to constitute rejection of such offer by such holder.

(d) Prepayment. Prepayment of the Notes to be prepaid pursuant to this Section 8.9 shall be at 100% of the principal amount of such Notes, together with interest on such Notes accrued to the Proposed Prepayment Date, but without Make-Whole Amount or other premium.

(f) Effect on Required Payments. The amount of each payment of the principal of a series of Notes made pursuant to this Section 8.9 shall be applied against and reduce each of the then remaining principal payments of such series due pursuant to Section 8.1 by a percentage equal to the aggregate principal amount of the Notes of such series so paid divided by the aggregate principal amount of the Notes of such series outstanding immediately prior to such payment.

(g) Certain Definitions. “Change in Control” shall be deemed to have occurred if, following the consummation of a transaction or a series of related transactions any person (as such term is used in Section 13(d) and Section 14(d)(2) of the Exchange Act as in effect on the date of the Closing) or related persons constituting a group (as such term is used in Rule 13d-5 under the Exchange Act),

(i) become the “beneficial owners” (as such term is used in Rule 13d-3 under the Exchange Act as in effect on the date of the Closing), directly or indirectly, of more than 50% of the total voting power of all classes then outstanding of the Company’s Voting Equity Capital, or

(ii) acquire after the date of the Closing (x) the power to elect, appoint or cause the election or appointment of at least a majority of the members of the board of directors of the Company through beneficial ownership of the capital stock of the Company or otherwise, or (y) all or substantially all of the consolidated properties and assets of the Company (other than by a Wholly-owned Subsidiary of the Company), or

(h) All calculations contemplated in this Section 8.9 involving the capital stock of any Person shall be made with the assumption that all convertible Securities of such Person then outstanding and all convertible Securities issuable upon the exercise of any warrants, options and other rights outstanding at such time were converted at such time and that all options, warrants and similar rights to acquire shares of capital stock of such Person were exercised at such time.

-31-

Section 9. Affirmative Covenants.

The Company covenants that so long as any of the Notes are outstanding:

Section 9.1. Compliance with Law. (a) Without limiting Section 10.13, the Company will, and will cause each of the Restricted Subsidiaries to, comply with all laws, ordinances or governmental rules or regulations to which each of them is subject, including, without limitation, ERISA, the USA Patriot Act and applicable laws in respect of Non-U.S. Pension Plans and all Environmental Laws, and the other laws and regulations that are referred to in Section 5.16, and will obtain and maintain in effect all licenses, certificates, permits, franchises and other governmental authorizations necessary to the ownership of their respective properties or to the conduct of their respective businesses, in each case to the extent necessary to ensure that non-compliance with such laws, ordinances or governmental rules or regulations or failures to obtain or maintain in effect such licenses, certificates, permits, franchises and other governmental authorizations could not, individually or in the aggregate, reasonably be expected to have a Material Adverse Effect.

(b) Without limiting Section 9.1(a), the Company will not, and will not permit any of the Restricted Subsidiaries to, take any action that would cause any supplemental pension plan, any employee pension arrangement or any employee benefit plan maintained by it to be terminated in a manner which could reasonably be anticipated to result in the imposition of a Material Lien on any property of the Company or any Restricted Subsidiary pursuant to any Canadian federal or provincial law, nor will the Company or any of the Restricted Subsidiaries withdraw from any multiemployer plan if such withdrawal would subject the Company or any of the Restricted Subsidiaries to a liability that would have a Material Adverse Effect.

Section 9.2. Insurance.

Section 12. Remedies on Default, Etc.

Section 12.1. Acceleration. (a) If an Event of Default with respect to the Company described in paragraph (i) or (j) or (k) of Section 11 (other than an Event of Default described in clause (i) of paragraph (i) or described in clause (vi) of paragraph (i) by virtue of the fact that such clause encompasses clause (i) of paragraph (i)) has occurred, all the Notes then outstanding shall automatically become immediately due and payable.

(b) If any other Event of Default has occurred and is continuing, any holder or holders of 51% or more in principal amount of the Notes at the time outstanding may at any time at its or their option, by notice or notices to the Company, declare all the Notes then outstanding to be immediately due and payable.

(c) If any Event of Default described in paragraph (a) or (b) of Section 11 has occurred and is continuing, any holder or holders of Notes at the time outstanding affected by such Event of Default may at any time, at its or their option, by notice or notices to the Company, declare all the Notes held by it or them to be immediately due and payable.

Upon any Note’s becoming due and payable under this Section 12.1, whether automatically or by declaration, such Note will forthwith mature and the entire unpaid principal amount of such Note, plus (i) all accrued and unpaid interest thereon (including, without limitation, interest accrued thereon at the Default Rate) and (ii) the Make-Whole Amount determined in respect of such principal amount (to the full extent permitted by applicable law), shall all be immediately due and payable, in each and every case without presentment, demand, protest or further notice, all of which are hereby waived. The Company acknowledges, and the parties hereto agree, that each holder of a Note has the right to maintain its investment in the Notes free from repayment by the Company (except as herein specifically provided for), and that the provision for payment of a Make-Whole Amount by the Company in the event that the Notes are prepaid or are accelerated as a result of an Event of Default, is intended to provide compensation for the deprivation of such right under such circumstances.

-44-

Section 12.2. Other Remedies. If any Default or Event of Default has occurred and is continuing, and irrespective of whether any Notes have become or have been declared immediately due and payable under Section 12.1, the holder of any Note at the time outstanding may proceed to protect and enforce the rights of such holder by an action at law, suit in equity or other appropriate proceeding, whether for the specific performance of any agreement contained herein or in any Note, or for an injunction against a violation of any of the terms hereof or thereof, or in aid of the exercise of any power granted hereby or thereby or by law or otherwise.

Section 12.3. Rescission. At any time after any Notes have been declared due and payable pursuant to clause (b) or (c) of Section 12.1, the holders of not less than 51% in principal amount of the Notes then outstanding, by written notice to the Company, may rescind and annul any such declaration and its consequences if (a) the Company has paid all overdue interest on the Notes, all principal of and Make-Whole Amount, if any, on any Notes that are due and payable and are unpaid other than by reason of such declaration, and all interest on such overdue principal and Make-Whole Amount, if any, and (to the extent permitted by applicable law) any overdue interest in respect of the Notes, at the Default Rate, (b) all Events of Default and Defaults, other than non-payment of amounts that have become due solely by reason of such declaration, have been cured or have been waived pursuant to Section 18, and (c) no judgment or decree has been entered for the payment of any monies due pursuant hereto or to the Notes. No rescission and annulment under this Section 12.3 will extend to or affect any subsequent Event of Default or Default or impair any right consequent thereon.

Section 12.4. No Waivers or Election of Remedies, Expenses, Etc. No course of dealing and no delay on the part of any holder of any Note in exercising any right, power or remedy shall operate as a waiver thereof or otherwise prejudice such holder’s rights, powers or remedies. No right, power or remedy conferred by this Agreement or by any Note upon any holder thereof shall be exclusive of any other right, power or remedy referred to herein or therein or now or hereafter available at law, in equity, by statute or otherwise. Without limiting the obligations of the Company under Section 16, the Company will pay to the holder of each Note on demand such further amount as shall be sufficient to cover all costs and expenses of such holder incurred in any enforcement or collection under this Section 12, including, without limitation, reasonable attorneys’ fees, expenses and disbursements.

Section 13. Tax Indemnification.

All payments whatsoever under this Agreement and the U.S. Dollar Notes will be made by the Company in lawful currency of the United States of America and, in the case of the Series A Notes, lawful currency of Canada, free and clear of, and without liability for withholding or deduction for or on account of, any present or future Taxes of whatever nature imposed or levied by or on behalf of any jurisdiction, unless the withholding or deduction of such Tax is compelled by law.

-45-

If any deduction or withholding for any Tax shall at any time be required in respect of any amounts to be paid by the Company under this Agreement or the Notes, the Company will pay to the relevant jurisdiction the full amount required to be withheld, deducted or otherwise paid before penalties attach thereto or interest accrues thereon and pay with respect to any deduction or withholding for any Tax of any jurisdiction other than the United States (or any political subdivision or taxing authority of or in such jurisdiction) (hereinafter a “Taxing Jurisdiction”) to each holder of a Note such additional amounts as may be necessary in order that the net amounts paid to such holder pursuant to the terms of this Agreement or the Notes after such deduction, withholding or payment (including, without limitation, any required deduction or withholding of Tax on or with respect to such additional amount), shall be not less than the amounts then due and payable to such holder under the terms of this Agreement or the Notes before the assessment of such Tax, provided that no payment of any additional amounts hereunder shall be required to be made for or on account of:

(a) any Tax that would not have been imposed but for the existence of any present or former connection between such holder (or a fiduciary, settlor, beneficiary, member of, shareholder of, or possessor of a power over, such holder, if such holder is an estate, trust, partnership or corporation or any Person other than the holder to whom the Notes or any amount payable thereon is attributable for the purposes of such Tax) and the Taxing Jurisdiction, other than the mere holding of the relevant Note or the receipt of payments thereunder or in respect thereof, including, without limitation, such holder (or such other Person described in the above parenthetical) being or having been a citizen or resident thereof, or being or having been present or engaged in trade or business therein or having or having had an establishment, office, fixed base or branch therein, provided that this exclusion shall not apply with respect to a Tax that would not have been imposed but for the Company, after the date of the Closing, opening an office in, moving an office to, reincorporating in, or changing the Taxing Jurisdiction from or through which payments on account of this Agreement or the Notes are made to, the Taxing Jurisdiction imposing the relevant Tax;

(b) any Tax that would not have been imposed but for the delay or failure by such holder (following a written request by the Company) in the filing with the relevant Taxing Jurisdiction or providing to the Company Forms (as defined below) that are required to be filed or provided by such holder to avoid or reduce such Taxes (including for such purpose any refilings or renewals that may from time to time be required by the relevant Taxing Jurisdiction), provided that the filing or provision of such Forms would not (in such holder’s reasonable judgment) impose any unreasonable burden (in time, resources or otherwise) on such holder or result in any confidential or proprietary income tax return information being revealed, either directly or indirectly, to any Person and such delay or failure could have been lawfully avoided by such holder, and provided further that such holder shall be deemed to have satisfied the requirements of this clause (b) upon the good faith completion and submission of such Forms (including refilings or renewals) as may be specified in a written request of the Company no later than 60 days after receipt by such holder of such written request (accompanied by copies of such Forms and related instructions, if any, all in the English language or with an English translation thereof); or

-46-

and, provided, further that in no event shall the Company be obligated to pay such additional amounts to any holder of a Note (i) not resident in the United States of America or any other jurisdiction in which you (being, for greater certainty, the purchaser of the Notes under this Agreement and not any substituted Purchaser pursuant to Section 22 or successor or assign (including, without limitation, any subsequent holder of a Note) pursuant to Section 23.3) are resident for tax purposes on the date of the Closing in excess of the amounts that the Company would be obligated to pay if such holder had been a resident of the United States of America or such other jurisdiction, as applicable, for purposes of, and eligible for the benefits of, any double taxation treaty from time to time in effect between the United States of America or such other jurisdiction and the relevant Taxing Jurisdiction or (ii) registered in the name of a nominee if under the law of the relevant Taxing Jurisdiction (or the current regulatory interpretation of such law) securities held in the name of a nominee do not qualify for an exemption from the relevant Tax and the Company shall have given timely notice of such law or interpretation to such holder.

Each holder shall, upon the occurrence of any event giving rise to the operation of this Section 13 with respect to such holder, if requested by the Company, use reasonable efforts (subject to overall policy considerations of such holder) to designate another lending office for any Note affected by such event with the object of avoiding the consequences of such event; provided, that such designation is made on terms that, in the sole judgment of such holder, cause such holder and its lending office(s) to suffer no economic, legal or regulatory disadvantage, and provided, further, that nothing in this paragraph shall affect or postpone any of the obligations of the Company or the rights of any holder pursuant to this Section 13.

By acceptance of any Note, the holder of such Note agrees, subject to the limitations of clause (b) above, that it will from time to time with reasonable promptness (x) duly complete and deliver to or as reasonably directed by the Company all such forms, certificates, documents and returns provided to such holder by the Company (collectively, together with instructions for completing the same, “Forms”) required to be provided or filed by or on behalf of such holder in order to avoid or reduce any such Tax pursuant to the provisions of an applicable statute, regulation or administrative practice of the relevant Taxing Jurisdiction or of a tax treaty entered into by such Taxing Jurisdiction and (y) provide the Company with such information with respect to such holder as the Company may reasonably request in order to complete any such Forms, provided that nothing in this Section 13 shall require any holder to provide information with respect to any such Form or otherwise if in the opinion of such holder such Form or disclosure of information would involve the disclosure of tax return or other information that is confidential or proprietary to such holder, and provided further that each such holder shall be deemed to have complied with its obligation under this paragraph with respect to any Form if such Form shall have been duly completed and delivered by such holder to the Company or mailed to the appropriate taxing authority, whichever is applicable, within 60 days following a written request of the Company (which request shall be accompanied by copies of such Form and English translations of any such Form not in the English language) and, in the case of a transfer of any Note, at least 90 days prior to the relevant interest payment date.

-47-

On or before the date of the Closing the Company will furnish you with copies of the appropriate Form (and English translation if required as aforesaid) currently required to be filed in Canada pursuant to clause (b) of the first paragraph of this Section 13, if any, and in connection with the transfer of any Note the Company will furnish the transferee of such Note with copies of any Form and English translation then required.

If any payment is made by the Company to or for the account of the holder of any Note after deduction for or on account of any Taxes, and increased payments are made by the Company pursuant to this Section 13, then, if such holder at its sole discretion determines that it has received or been granted a refund of such Taxes, such holder shall, to the extent that it can do so without prejudice to the retention of the amount of such refund, reimburse to the Company such amount as such holder shall, in its sole discretion, determine to be attributable to the relevant Taxes or deduction or withholding. Nothing herein contained shall interfere with the right of the holder of any Note to arrange its tax affairs in whatever manner it thinks fit and, in particular, no holder of any Note shall be under any obligation to claim relief from its corporate profits or similar tax liability in respect of such Tax in priority to any other claims, reliefs, credits or deductions available to it or (other than as set forth in clause (b) above) oblige any holder of any Note to disclose any information relating to its tax affairs or any computations in respect thereof.

The Company will furnish the holders of Notes, promptly and in any event within 60 days after the date of any payment by the Company of any Tax in respect of any amounts paid under this Agreement or the Notes, the original tax receipt issued by the relevant taxation or other authorities involved for all amounts paid as aforesaid (or if such original tax receipt is not available or must legally be kept in the possession of the Company, a duly certified copy of the original tax receipt or any other reasonably satisfactory evidence of payment), together with such other documentary evidence with respect to such payments as may be reasonably requested from time to time by any holder of a Note.

If the Company is required by any applicable law, as modified by the practice of the taxation or other authority of any relevant Taxing Jurisdiction, to make any deduction or withholding of any Tax in respect of which the Company would be required to pay any additional amount under this Section 13, but for any reason does not make such deduction or withholding with the result that a liability in respect of such Tax is assessed directly against the holder of any Note, and such holder pays such liability, then the Company will promptly reimburse such holder for such payment (including any related interest or penalties to the extent such interest or penalties arise by virtue of a default or delay by the Company) upon demand by such holder accompanied by an official receipt (or a duly certified copy thereof) issued by the taxation or other authority of the relevant Taxing Jurisdiction.

-48-

If the Company makes payment to or for the account of any holder of a Note and such holder is entitled to a refund of the Tax to which such payment is attributable upon the making of a filing (other than a Form described above), then such holder shall, as soon as practicable after receiving written request from the Company (which shall specify in reasonable detail and supply the refund forms to be filed), use reasonable efforts to complete and deliver such refund forms to or as directed by the Company, subject, however, to the same limitations with respect to Forms as are set forth above.

The obligations of the Company under this Section 13 shall survive the payment or transfer of any Note and the provisions of this Section 13 shall also apply to successive transferees of the Notes.

Section 14. Registration; Exchange; Substitution of Notes.

Section 14.1. Registration of Notes. The Company shall keep at its principal executive office a register for the registration and registration of transfers of Notes. The name and address of each holder of one or more Notes, each transfer thereof and the name and address of each transferee of one or more Notes shall be registered in such register. Prior to due presentment for registration of transfer, the Person in whose name any Note shall be registered shall be deemed and treated as the owner and holder thereof for all purposes hereof, and the Company shall not be affected by any notice or knowledge to the contrary. The Company shall give to any holder of a Note that is an Institutional Investor promptly upon request therefor, a complete and correct copy of the names and addresses of all registered holders of Notes.

Section 14.2. Transfer and Exchange of Notes. Upon surrender of any Note to the Company at the address and to the attention of the designated officer (all as specified in Section 19) for registration of transfer or exchange (and in the case of a surrender for registration of transfer, duly endorsed or accompanied by a written instrument of transfer duly executed by the registered holder of such Note or its attorney duly authorized in writing and accompanied by the address for notices of each transferee of such Note or part thereof) within ten Business Days thereafter, the Company shall execute and deliver, at the Company’s expense (except as provided below), one or more new Notes of the same series (as requested by the holder thereof) in exchange therefor, in an aggregate principal amount equal to the unpaid principal amount of the surrendered Note of such series. Each such new Note shall be payable to such Person as such holder may request and shall be substantially in the form of Exhibit 1-A, Exhibit 1-B and Exhibit 1-C, as the case may be. Each such new Note shall be dated and bear interest from the date to which interest shall have been paid on the surrendered Note or dated the date of the surrendered Note if no interest shall have been paid thereon. The Company may require payment of a sum sufficient to cover any stamp tax or governmental charge imposed in respect of any such transfer of Notes. Notes shall not be transferred in denominations of less than U.S. $500,000 or Cdn. $500,000, as applicable; provided that if necessary to enable the registration of transfer by a holder of its entire holding of Notes, one Note may be in a denomination of less than U.S. $500,000 or Cdn. $500,000, as applicable. Any transferee, by its acceptance of a Note registered in its name (or the name of its nominee), shall be deemed to have made the representation set forth in Section 6.2.

Section 14.3. Replacement of Notes. Upon receipt by the Company at the address and to the attention of the designated officer (all as specified in Section 19(iii)) of evidence reasonably satisfactory to it of the ownership of and the loss, theft, destruction or mutilation of any Note (which evidence shall be, in the case of an Institutional Investor, notice from such Institutional Investor of such ownership and such loss, theft, destruction or mutilation), and

-49-

(a) in the case of loss, theft or destruction, of indemnity reasonably satisfactory to it (provided that if the holder of such Note is, or is a nominee for, an original Purchaser or another holder of a Note with a minimum net worth of at least U.S.$25,000,000 or a Qualified Institutional Buyer, such Person’s own unsecured agreement of indemnity shall be deemed to be satisfactory), or

(b) in the case of mutilation, upon surrender and cancellation thereof,

within ten Business Days thereafter the Company at its own expense shall execute and deliver, in lieu thereof, a new Note of the same series, dated and bearing interest from the date to which interest shall have been paid on such lost, stolen, destroyed or mutilated Note or dated the date of such lost, stolen, destroyed or mutilated Note if no interest shall have been paid thereon.

Section 15. Payments on Notes.

Section 15.1. Place of Payment. Subject to Section 15.2, payments of principal, Make-Whole Amount, if any, and interest becoming due and payable on the Notes shall be made in Calgary, Canada at the principal office of the Company in such jurisdiction. The Company may at any time, by notice to each holder of a Note, change the place of payment of the Notes so long as such place of payment shall be either the principal office of the Company in such jurisdiction or the principal office of a bank or trust company in such jurisdiction.

Section 15.2. Home Office Payment. So long as you or your nominee shall be the holder of any Note, and notwithstanding anything contained in Section 15.1 or in such Note to the contrary, the Company will pay all sums becoming due on such Note for principal, Make-Whole Amount, if any, and interest by the method and at the address specified for such purpose below your name in Schedule A, or by such other method or at such other address as you shall have from time to time specified to the Company in writing for such purpose, without the presentation or surrender of such Note or the making of any notation thereon, except that upon written request of the Company made concurrently with or reasonably promptly after payment or prepayment in full of any Note, you shall surrender such Note for cancellation, reasonably promptly after any such request, to the Company at its principal executive office or at the place of payment most recently designated by the Company pursuant to Section 15.1. The Company will make such payments in immediately available funds, no later than 11:00 a.m. New York, New York time on the date due. If for any reason whatsoever the Company does not make any such payment by such 11:00 a.m. transmittal time, such payment shall be deemed to have been made on the next following Business Day and such payment shall bear interest at the Default Rate set forth in the Note. Prior to any sale or other disposition of any Note held by you or your nominee you will, at your election, either endorse thereon the amount of principal paid thereon and the last date to which interest has been paid thereon or surrender such Note to the Company in exchange for a new Note or Notes of the same series pursuant to Section 14.2. The Company will afford the benefits of this Section 15.2 to any Institutional Investor that is the direct or indirect transferee of any Note purchased by you under this Agreement and that has made the same agreement relating to such Note as you have made in this Section 15.2.

-50-

The Company agrees to pay all stamp, documentary or similar taxes or fees which may be payable in respect of the execution and delivery or the enforcement of this Agreement or the execution and delivery (but not the transfer) or the enforcement of any of the Notes in the United States or Canada or of any amendment of, or waiver or consent under or with respect to, this Agreement, any of the Notes, the Subsidiary Guaranty or any of the Subordination Agreements and to pay any value added tax due and payable in respect of reimbursement of costs and expenses by the Company, any Subsidiary Guarantor or any other party to any of the Subordination Agreements pursuant to this Section 16, and will save each holder of a Note to the extent permitted by applicable law harmless against any loss or liability resulting from nonpayment or delay in payment of any such tax or fee required to be paid by the Company hereunder.

-51-

Section 17. Survival of Representations and Warranties; Entire Agreement.

All representations and warranties contained herein shall survive the execution and delivery of this Agreement, the Notes, the Subsidiary Guaranty and the Subordination Agreements, the purchase or transfer by you of any Note or portion thereof or interest therein and the payment of any Note, and may be relied upon by any subsequent holder of a Note, regardless of any investigation made at any time by or on behalf of you or any other holder of a Note. All statements contained in any certificate or other instrument delivered by or on behalf of the Company pursuant to this Agreement shall be deemed representations and warranties of the Company, or any Subsidiary Guarantor, as the case may be, pursuant to this Agreement, the Subsidiary Guaranty or the Subordination Agreement to which it is a party. Subject to the preceding sentence, this Agreement, the Notes, the Subsidiary Guaranty and the Subordination Agreement embody the entire agreement and understanding between you and the Company and supersede all prior agreements and understandings relating to the subject matter hereof.

Section 18. Amendment and Waiver.

Section 18.1. Requirements. This Agreement, the Notes, the Subsidiary Guaranty and each Subordination Agreement may be amended, and the observance of any term hereof or of the Notes may be waived (either retroactively or prospectively), with (and only with) the written consent of the Company and the Required Holders, except that (a) no amendment or waiver of any of the provisions of Section 1, 2.1, 3, 4, 5, 6 or 22 hereof, or any defined term (as it is used therein), will be effective as to you unless consented to by you in writing, and (b) no such amendment or waiver may, without the written consent of the holder of each Note at the time outstanding affected thereby, (i) subject to the provisions of Section 12 relating to acceleration or rescission, change the amount or time of any prepayment or payment of principal of, or reduce the rate or change the time of payment or method of computation of interest or of the Make-Whole Amount on, the Notes or any series thereof, (ii) change the percentage of the principal amount of the Notes the holders of which are required to consent to any such amendment or waiver, or (iii) amend any of Section 8, 11(a), 11(b), 12, 13, 14.3, 18 or 21 or 23.9.

Section 18.2. Solicitation of Holders of Notes.

(a) Solicitation. The Company will provide each holder of the Notes (irrespective of the amount or series of Notes then owned by it) with sufficient information, sufficiently far in advance of the date a decision is required, to enable such holder to make an informed and considered decision with respect to any proposed amendment, waiver or consent in respect of any of the provisions hereof or of the Notes, the Subsidiary Guaranty or any Subordination Agreement. The Company will deliver executed or true and correct copies of each amendment, waiver or consent effected pursuant to the provisions of this Section 18 to each holder of outstanding Notes promptly following the date on which it is executed and delivered by, or receives the consent or approval of, the requisite holders of Notes.

-52-

(b) Payment. The Company will not directly or indirectly pay or cause to be paid any remuneration, whether by way of supplemental or additional interest, fee or otherwise, or grant any security or provide other credit support, to any holder of any series of Notes as consideration for or as an inducement to the entering into by any holder of Notes of any waiver or amendment of any of the terms and provisions hereof or of the Subsidiary Guaranty or any Subordination Agreement unless such remuneration is concurrently paid, or security is concurrently granted or other credit support concurrently provided, on the same terms, ratably to each holder of Notes of each series then outstanding even if such holder did not consent to such waiver or amendment.

(c) Consent in Contemplation of Transfer. Any consent made pursuant to this Section 18.2 by the holder of any Note that has transferred or has agreed to transfer, or has accepted an offer of prepayment of, such Note to the Company, any Subsidiary or any Affiliate of the Company and has provided or has agreed to provide such written consent as a condition to such transfer or prepayment shall be void and of no force or effect except solely as to such holder, and any amendments effected or waivers granted or to be effected or granted that would not have been or would not be so effected or granted but for such consent (and the consents of all other holders of Notes that were acquired under the same or similar conditions) shall be void and of no force or effect except solely as to such transferring holder or holder whose Note is being prepaid.

Section 18.3. Binding Effect, Etc. Any amendment or waiver consented to as provided in this Section 18 applies equally to all holders of each series of Notes and is binding upon them and upon each future holder of any Note of each series and upon the Company without regard to whether such Note has been marked to indicate such amendment or waiver. No such amendment or waiver will extend to or affect any obligation, covenant, agreement, Default or Event of Default not expressly amended or waived or impair any right consequent thereon. No course of dealing between the Company and the holder of any Note of any series nor any delay in exercising any rights hereunder or under any Note of any series, the Subsidiary Guaranty or any Subordination Agreement shall operate as a waiver of any rights of any holder of such Note. As used herein, the term “this Agreement” and references thereto shall mean this Agreement as it may from time to time be amended or supplemented.

Section 18.4. Notes Held by Company, Etc. Solely for the purpose of determining whether the holders of the requisite percentage of the aggregate principal amount of Notes then outstanding approved or consented to any amendment, waiver or consent to be given under this Agreement, the Notes, the Subsidiary Guaranty or any Subordination Agreement or have directed the taking of any action provided herein or in the Notes to be taken upon the direction of the holders of a specified percentage of the aggregate principal amount of Notes then outstanding, Notes directly or indirectly owned by the Company or any of its Affiliates shall be deemed not to be outstanding.

Section 23. Miscellaneous.

Section 23.1. Interest Act of Canada. For the purposes of the Interest Act (Canada) and disclosure thereunder, whenever interest to be paid hereunder or in connection herewith is to be calculated on the basis of a year of 360 days consisting of twelve 30-day months, the yearly rate of interest to which the rate used in such calculation is equivalent during any particular period is the rate so used multiplied by a fraction of which:

(a) the numerator is the product of:

(i) the actual number of days in the calendar year in which such period ends; and

(ii) the sum of (A) the product of 30 and the number of complete months elapsed in the relevant period, and (B) the number of days elapsed in any incomplete month in the relevant period; and

(b) the denominator is the product of 360 and the actual number of days in the relevant period.

Section 23.2. Time. Time shall be of the essence of this Agreement. The mere lapse of the time provided for the Company to perform its obligations or the arrival of the term shall automatically create a default, without any notice being required.

Section 23.3. Successors and Assigns. All covenants and other agreements contained in this Agreement by or on behalf of any of the parties hereto bind and inure to the benefit of their respective successors and assigns (including, without limitation, any subsequent holder of a Note) whether so expressed or not; provided that no successor or assignee shall be entitled to receive any greater amount pursuant to Section 13 than that to which the assignor would have been entitled to receive had no such assignment occurred.

Section 23.4. Payments Due on Non-Business Days. Anything in this Agreement or the Notes to the contrary notwithstanding (but without limiting the requirement in Section 8.6 that notice of any optional prepayment specify a Business Day as the date fixed for such prepayment), any payment of principal of or Make-Whole Amount or interest on any Note that is due on a date other than a Business Day shall be made on the next succeeding Business Day without including the additional days elapsed in the computation of the interest payable on such next succeeding Business Day; provided that if the maturity date of any Note is a date other than a Business Day, the payment otherwise due on such maturity date shall be made on the next succeeding Business Day and shall include the additional days elapsed in the computation of interest payable on such next succeeding Business Day.

-56-

Section 23.5. Accounting Terms. (a) All accounting terms used herein which are not expressly defined in this Agreement have the meanings respectively given to them in accordance with GAAP. Except as otherwise specifically provided herein, all computations made pursuant to this Agreement shall be made in accordance with GAAP, and all financial statements shall be prepared in accordance with GAAP. For purposes of determining compliance with the financial covenants contained in this Agreement, any election by the Company to measure an item of Debt using fair value (as permitted by International Accounting Standard 39 or any similar accounting standard) shall be disregarded and such determination shall be made as if such election had not been made.

(b) If:

(i) there occurs a material change in GAAP; or

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

and in either case the above change would require disclosure under GAAP in the consolidated financial statements of the Company and would cause an amount required to be determined for the purposes of a financial covenant under Section 10.1, 10.2 or 10.3 or otherwise (a “Financial Covenant”) to be materially different than the amount that would be determined without giving effect to such change, the Company shall notify each holder of such change (an “Accounting Change”). Such notice (an “Accounting Change Notice”) shall describe the nature of the Accounting Change, its effect or anticipated effect on the current and immediately prior year’s financial statements in accordance with GAAP and state whether the Company desires to revise the method of calculating one or more of the Financial Covenants (including the revision of any of the defined terms used in the determination of such Financial Covenant) in order that amounts determined after giving effect to such Accounting Change and the revised method of calculating such Financial Covenant will approximate the amount that would be determined without giving effect to such Accounting Change and without giving effect to the revised method of calculating such Financial Covenant. The Accounting Change Notice shall be delivered to the holders within 60 days of the end of the fiscal quarter in which the Accounting Change is implemented or, if such Accounting Change is implemented in the fourth fiscal quarter or in respect of an entire fiscal year, within 120 days of the end of such period.

If, pursuant to the Accounting Change Notice, the Company does not indicate that it desires to revise the method of calculating one or more of the Financial Covenants, the Required Holders may, within 30 days of receipt of the date of the Accounting Change Notice, notify the Company that they wish to revise the method of calculating one or more of the Financial Covenants in the manner described above.

-57-

If either the Company or the Required Holders so indicate that they wish to revise the method of calculating one or more of the Financial Covenants, the Company and the Required Holders shall in good faith attempt to agree on a revised method of calculating the Financial Covenants. If, however, within 120 days of the foregoing notice by the Company or the Required Holders of their desire to revise the method of calculating one or more of the Financial Covenants, the Company and the Required Holders have not reached agreement in writing on such revised method of calculation, such method of calculation shall not be revised and all amounts to be determined thereunder shall be determined without giving effect to the Accounting Change. For greater certainty, if no notice of a desire to revise the method of calculating the Financial Covenants in respect of an Accounting Change is given by either the Company or the Required Holders within the applicable time period described above, the method of calculating the Financial Covenants shall not be revised in response to such Accounting Change and all amounts to be determined pursuant to the Financial Covenants shall be determined after giving effect to such Accounting Change.

If a certificate is delivered pursuant to Section 7.2 in respect of a fiscal quarter or fiscal year in which an Accounting Change is implemented without giving effect to any revised method of calculating any of the Financial Covenants, and subsequently, as provided above, the method of calculating one or more of the Financial Covenants is revised in response to such Accounting Change, or the amounts to be determined pursuant to any of the Financial Covenants are to be determined without giving effect to such Accounting Change, the Company shall deliver within 30 days of such revision a revised certificate in accordance with Section 7.2. Any Default or Event of Default arising as a result of the Accounting Change and which is cured by this Section 23.5 shall be deemed to be of no effect ab initio.

Section 23.6. Severability. Any provision of this Agreement that is prohibited or unenforceable in any jurisdiction shall, as to such jurisdiction, be ineffective to the extent of such prohibition or unenforceability without invalidating the remaining provisions hereof, and any such prohibition or unenforceability in any jurisdiction shall (to the full extent permitted by law) not invalidate or render unenforceable such provision in any other jurisdiction.

Section 23.7. Construction, Etc. Each covenant contained herein shall be construed (absent express provision to the contrary) as being independent of each other covenant contained herein, so that compliance with any one covenant shall not (absent such an express contrary provision) be deemed to excuse compliance with any other covenant. Where any provision herein refers to action to be taken by any Person, or which such Person is prohibited from taking, such provision shall be applicable whether such action is taken directly or indirectly by such Person.

For the avoidance of doubt, all Schedules and Exhibits attached to this Agreement shall be deemed to be a part hereof.

Section 23.8. Counterparts. This Agreement may be executed in any number of counterparts, each of which shall be an original but all of which together shall constitute one instrument. Each counterpart may consist of a number of copies hereof, each signed by less than all, but together signed by all, of the parties hereto.

Section 23.9. Governing Law. This Agreement shall be construed and enforced in accordance with, and the rights of the parties shall be governed by, the law of the Province of Alberta and the laws of Canada applicable therein, excluding choice-of-law principles of the law of such Province that would require the application of the laws of a jurisdiction other than such Province.

The Company agrees that such service upon receipt (i) shall be deemed in every respect effective service of process upon it in any such suit, action or proceeding and (ii) shall, to the fullest extent permitted by applicable law, be taken and held to be valid personal service upon and personal delivery to it. Notices hereunder shall be conclusively presumed received as evidenced by a delivery receipt furnished by the United States Postal Service or any reputable commercial delivery service.

(c) Nothing in this Section 23.10 shall affect the right of any holder of a Note to serve process in any manner permitted by law, or limit any right that the holders of any of the Notes may have to bring proceedings against the Company in the courts of any appropriate jurisdiction or to enforce in any lawful manner a judgment obtained in one jurisdiction in any other jurisdiction.

Article 6

Affirmative Covenants

Each Guarantor covenants that so long as this Agreement remains outstanding:

Section 6.1. Compliance with Law. (a) Such Guarantor will comply with all laws, ordinances or governmental rules or regulations to which each of them is subject, including, without limitation, ERISA, the USA Patriot Act and applicable laws in respect of Non-U.S. Pension Plans and all Environmental Laws, and will obtain and maintain in effect all licenses, certificates, permits, franchises and other governmental authorizations necessary to the ownership of their respective properties or to the conduct of its businesses, in each case to the extent necessary to ensure that non-compliance with such laws, ordinances or governmental rules or regulations or failures to obtain or maintain in effect such licenses, certificates, permits, franchises and other governmental authorizations could not, individually or in the aggregate, reasonably be expected to have a Material Adverse Effect.

(b) Without limiting Section 6.1(a), such Guarantor will not take any action that would cause any supplemental pension plan, any employee pension arrangement or any employee benefit plan maintained by it to be terminated in a manner which could reasonably be anticipated to result in the imposition of a Material Lien on any property of such Guarantor pursuant to any Canadian federal or provincial law, nor will such Guarantor withdraw from any multiemployer plan if such withdrawal would subject such Guarantor to a liability that would have a Material Adverse Effect.

Section 6.2. Insurance. Such Guarantor will maintain, with financially sound and reputable insurers, insurance with respect to their respective properties and businesses against such casualties and contingencies, of such types, on such terms and in such amounts (including deductibles, co-insurance and self-insurance, if adequate reserves are maintained with respect thereto) as is customary in the case of entities of established reputations engaged in the same or a similar business and similarly situated.

Section 6.3. Maintenance of Properties. Such Guarantor will maintain and keep, or cause to be maintained and kept, its properties in good repair, working order and condition (other than ordinary wear and tear), so that the business carried on in connection therewith may be properly conducted at all times; provided that this Section 6.3 shall not prevent such Guarantor from discontinuing the operation and the maintenance of any of its properties if such discontinuance is desirable in the conduct of its business and such Guarantor has concluded that such discontinuance could not, individually or in the aggregate, reasonably be expected to have a Material Adverse Effect.

-12-

Section 6.4. Payment of Taxes and Claims. Such Guarantor will file all tax returns required to be filed in any jurisdiction and to pay and discharge all taxes shown to be due and payable on such returns and all other taxes, assessments, governmental charges, or levies imposed on them or any of their properties, assets, income or franchises, to the extent such taxes and assessments have become due and payable and before they have become delinquent and all claims for which sums have become due and payable that have or might become a Lien on properties or assets of such Guarantor; provided that such Guarantor need not pay or discharge any such tax assessment, charge or levy if (a) the amount, applicability or validity thereof is contested by such Guarantor on a timely basis in good faith and in appropriate proceedings, and such Guarantor has established adequate reserves therefor in accordance with GAAP on the books of the Company or such Guarantor or (b) the nonpayment of all such taxes, assessments, charges and levies in the aggregate could not reasonably be expected to have a Material Adverse Effect.

Section 6.5. Legal Existence, Etc. Subject to and except as permitted by Sections 10.6 and 10.7 and by Section 23.3 of the Note Purchase Agreement, such Guarantor will at all times preserve and keep in full force and effect its legal existence (unless merged, amalgamated, consolidated or wound-up into the Company or a Wholly-owned Subsidiary) and all rights and franchises of such Guarantor unless, in the good faith judgment of such Guarantor, the termination of or failure to preserve and keep in full force and effect such corporate existence, right or franchise could not, individually or in the aggregate, have a Material Adverse Effect.

Section 6.6. Nature of Business. Such Guarantor will not engage in any business if, as a result, the general nature of the business, taken on a consolidated basis, which would then be engaged in by such Guarantor and its Subsidiaries would be substantially changed from its business relating to the development, production, processing and transportation of hydrocarbons.

Section 6.7. Guarantee to Rank Pari Passu. All obligations under this Agreement of such Guarantor are and at all times shall remain direct and unsecured obligations of such Guarantor ranking pari passu as against the assets of such Guarantor with all other present and future unsecured Debt (actual or contingent) of such Guarantor which is not expressed to be subordinate or junior in rank to any other unsecured Debt of such Guarantor.

-13-

Section 8.1. Organization; Power and Authority. Such Guarantor is a legal entity duly organized, validly existing and in good standing under the laws of its jurisdiction of organization, and is in good standing in each jurisdiction in which such qualification is required by law, other than those jurisdictions as to which the failure to be so qualified or in good standing could not, individually or in the aggregate, reasonably be expected to have a Material Adverse Effect. Such Guarantor has the power and authority to own or hold under lease the properties it purports to own or hold under lease, to transact the business it transacts and proposes to transact, to execute and deliver this Agreement and to perform the provisions hereof. Each Guarantor is subject to the relevant commercial law and civil law and is generally subject to suit and it is not, nor does any of its properties or revenues, enjoy any right of immunity from any judicial proceedings, including attachment prior to judgment, attachment in aid of execution, execution of the judgment or otherwise. Such Guarantor represents that the execution and delivery of this Agreement constitute private and commercial acts rather than governmental or public acts of such Guarantor.

Section 8.3. Compliance with Laws, Other Instruments, Etc. The execution, delivery and performance by such Guarantor of this Agreement will not (a) contravene, result in any breach of, or constitute a default under, or result in the creation of any Lien in respect of any property of such Guarantor under, any indenture, mortgage, deed of trust, loan, purchase or credit agreement, lease, corporate charter or by-laws or the legal equivalent of the foregoing, or any other agreement or instrument to which such Guarantor is bound or by which such Guarantor or any of its respective properties may be bound or affected, (b) conflict with or result in a breach of any of the terms, conditions or provisions of any order, judgment, decree, or ruling of any court, arbitrator or Governmental Authority applicable to such Guarantor, or (c) violate any provision of any statute or other rule or regulation of any Governmental Authority applicable to such Guarantor.

Section 8.4. Governmental Authorizations, Etc. No consent, approval or authorization of, or registration, filing or declaration with, any Governmental Authority is required in connection with the execution, delivery or performance by such Guarantor of this Agreement, including, without limitation, any thereof required in connection with the obtaining of U.S. Dollars to make payments under this Agreement or the U.S. Dollar Notes and the payment of such U.S. Dollars to Persons resident in the United States of America or Japan, other than (i) the filing of a Form 45-106F1 with the applicable Canadian securities regulatory authorities on or before the tenth day following the date of Closing, together with the applicable fees, and (ii) the filing of the Memorandum and any other document that constitutes an “offering memorandum” within the meaning of applicable Canadian provincial securities laws with the applicable Canadian securities regulatory authorities, together with the applicable fees. It is not necessary to ensure the legality, validity, enforceability or admissibility into evidence in Canada of this Agreement that this Agreement or any other document be filed, recorded or enrolled with any Governmental Authority, or that any such agreement or document be stamped with any stamp, registration or similar transaction tax that may be required in connection with admissibility into evidence.

-14-

Section 8.5. Foreign Assets Control Regulations, Etc. Neither such Guarantor nor any Subsidiary is a Blocked Person. To such Guarantor’s actual knowledge after making due inquiry, neither such Guarantor nor any Subsidiary (i) is under investigation by any Governmental Authority for, or has been charged with, or convicted under Anti-Money Laundering Laws, (ii) has been assessed civil penalties under any Anti-Money Laundering Laws or (iii) has had any of its funds seized or forfeited in an action under any Anti-Money Laundering Laws. Such Guarantor has taken reasonable measures appropriate to the circumstances (in any event as required by applicable law) to ensure that such Guarantor and each Subsidiary is in compliance with all applicable current Anti-Money Laundering Laws.

Section 8.6. Guarantee Rank Pari Passu. The obligations of such Guarantor under this Agreement rank at least pari passu in right of payment with all other senior unsecured Debt (actual or contingent) of such Guarantor, including, without limitation, all senior unsecured Debt of such Guarantor described in Schedule 5.15 of the Note Purchase Agreement.

Section 9.11. Obligation to Make Payment in Dollars. Any payment on account of an amount that is payable hereunder in U.S. Dollars which is made to or for the account of any holder of U.S. Dollar Notes in any other currency, whether as a result of any judgment or order or the enforcement thereof or the realization of any security or the liquidation of each Guarantor, shall constitute a discharge of the obligation of the Guarantors under this Agreement only to the extent of the amount of U.S. Dollars which such holder could purchase in the foreign exchange markets in New York, New York, with the amount of such other currency in accordance with normal banking procedures at the rate of exchange prevailing on the New York Banking Day following receipt of the payment first referred to above. If the amount of U.S. Dollars that could be so purchased is less than the amount of U.S. Dollars originally due to such holder, each Guarantor agrees to the fullest extent permitted by law, to indemnify and save harmless such holder from and against all loss or damage arising out of or as a result of such deficiency. This indemnity shall, to the fullest extent permitted by law, constitute an obligation separate and independent from the other obligations contained in this Agreement, shall give rise to a separate and independent cause of action, shall apply irrespective of any indulgence granted by such holder from time to time and shall continue in full force and effect notwithstanding any judgment or order for a liquidated sum in respect of an amount due hereunder or under the Notes or under any judgment or order. As used herein the term “New York Banking Day” shall mean any day other than Saturday or Sunday or a day on which commercial banks are required or authorized by law to be closed in New York, New York.

Section 9.12. Copy Received. Each Guarantor acknowledges receipt of a copy of this Agreement.

Section 9.13. Time of the Essence. Time shall be of the essence.

Section 9.14. Tax Indemnification. All payments whatsoever under this Agreement with respect to the U.S. Dollar Notes will be made by each Guarantor in lawful currency of the United States of America free and clear of, and without liability for withholding or deduction for or on account of, any present or future Taxes of whatever nature imposed or levied by or on behalf of any jurisdiction, unless the withholding or deduction of such Tax is compelled by law.

If any deduction or withholding for any Tax shall at any time be required in respect of any amounts to be paid by any Guarantor under this Agreement with respect to the U.S. Dollar Notes, such Guarantor will pay to the relevant jurisdiction the full amount required to be withheld, deducted or otherwise paid before penalties attach thereto or interest accrues thereon and pay with respect to any deduction or withholding for any Tax of any jurisdiction other than the United States (or any political subdivision or taxing authority of or in such jurisdiction) (hereinafter a “Taxing Jurisdiction”) to each holder of a U.S. Dollar Note such additional amounts as may be necessary in order that the net amounts paid to such holder pursuant to the terms of this Agreement or the U.S. Dollar Notes after such deduction, withholding or payment (including, without limitation, any required deduction or withholding of Tax on or with respect to such additional amount), shall be not less than the amounts then due and payable to such holder under the terms of this Agreement or the U.S. Dollar Notes before the assessment of such Tax, provided that no payment of any additional amounts hereunder shall be required to be made for or on account of:

-17-

(a) any Tax that would not have been imposed but for the existence of any present or former connection between such holder (or a fiduciary, settlor, beneficiary, member of, shareholder of, or possessor of a power over, such holder, if such holder is an estate, trust, partnership or corporation or any Person other than the holder to whom the U.S. Dollar Notes or any amount payable thereon is attributable for the purposes of such Tax) and the Taxing Jurisdiction, other than the mere holding of the relevant Note or the receipt of payments thereunder or in respect thereof, including, without limitation, such holder (or such other Person described in the above parenthetical) being or having been a citizen or resident thereof, or being or having been present or engaged in trade or business therein or having or having had an establishment, office, fixed base or branch therein, provided that this exclusion shall not apply with respect to a Tax that would not have been imposed but for a Guarantor, after the date of the Closing, opening an office in, moving an office to, reincorporating in, or changing the Taxing Jurisdiction from or through which payments on account of this Agreement or the U.S. Dollar Notes are made to, the Taxing Jurisdiction imposing the relevant Tax;

(b) any Tax that would not have been imposed but for the delay or failure by such holder (following a written request by the Guarantors) in the filing with the relevant Taxing Jurisdiction or providing to each Guarantor Forms (as defined below) that are required to be filed or provided by such holder to avoid or reduce such Taxes (including for such purpose any refilings or renewals that may from time to time be required by the relevant Taxing Jurisdiction), provided that the filing or provision of such Forms would not (in such holder’s reasonable judgment) impose any unreasonable burden (in time, resources or otherwise) on such holder or result in any confidential or proprietary income tax return information being revealed, either directly or indirectly, to any Person and such delay or failure could have been lawfully avoided by such holder, and provided further that such holder shall be deemed to have satisfied the requirements of this clause (b) upon the good faith completion and submission of such Forms (including refilings or renewals) as may be specified in a written request of any Guarantor no later than 60 days after receipt by such holder of such written request (accompanied by copies of such Forms and related instructions, if any, all in the English language or with an English translation thereof); or

and, provided, further that in no event shall any Guarantor be obligated to pay such additional amounts to any holder of a U.S. Dollar Note (i) not resident in the United States of America or any other jurisdiction in which the purchaser of the Notes under the Note Purchase Agreement and not any substituted Purchaser pursuant to Section 22 of the Note Purchase Agreements or successor or assign (including, without limitation, any subsequent holder of a Note) pursuant to Section 23.3 of the Note Purchase Agreements) are resident for tax purposes on the date of the Closing in excess of the amounts that such Guarantor would be obligated to pay if such holder had been a resident of the United States of America or such other jurisdiction, as applicable, for purposes of, and eligible for the benefits of, any double taxation treaty from time to time in effect between the United States of America or such other jurisdiction and the relevant Taxing Jurisdiction or (ii) registered in the name of a nominee if under the law of the relevant Taxing Jurisdiction (or the current regulatory interpretation of such law) securities held in the name of a nominee do not qualify for an exemption from the relevant Tax and such Guarantor shall have given timely notice of such law or interpretation to such holder.

-18-

Each holder of a U.S. Dollar Note shall, upon the occurrence of any event giving rise to the operation of this Section 9.14 with respect to such holder, if requested by any Guarantor, use reasonable efforts (subject to overall policy considerations of such holder) to designate another lending office for any U.S. Dollar Note affected by such event with the object of avoiding the consequences of such event; provided, that such designation is made on terms that, in the sole judgment of such holder, cause such holder and its lending office(s) to suffer no economic, legal or regulatory disadvantage, and provided, further, that nothing in this paragraph shall affect or postpone any of the obligations of such Guarantor or the rights of any holder pursuant to this Section 9.14.

By acceptance of any U.S. Dollar Note, the holder of such U.S. Dollar Note agrees, subject to the limitations of clause (b) above, that it will from time to time with reasonable promptness (x) duly complete and deliver to or as reasonably directed by any Guarantor all such forms, certificates, documents and returns provided to such holder by such Guarantor (collectively, together with instructions for completing the same, “Forms”) required to be provided or filed by or on behalf of such holder in order to avoid or reduce any such Tax pursuant to the provisions of an applicable statute, regulation or administrative practice of the relevant Taxing Jurisdiction or of a tax treaty entered into by such Taxing Jurisdiction and (y) provide such Guarantor with such information with respect to such holder as such Guarantor may reasonably request in order to complete any such Forms, provided that nothing in this Section 9.14 shall require any holder to provide information with respect to any such Form or otherwise if in the opinion of such holder such Form or disclosure of information would involve the disclosure of tax return or other information that is confidential or proprietary to such holder, and provided further that each such holder shall be deemed to have complied with its obligation under this paragraph with respect to any Form if such Form shall have been duly completed and delivered by such holder to each Guarantor or mailed to the appropriate taxing authority, whichever is applicable, within 60 days following a written request of such Guarantor (which request shall be accompanied by copies of such Form and English translations of any such Form not in the English language) and, in the case of a transfer of any Note, at least 90 days prior to the relevant interest payment date.

On or before the date of the Closing the Guarantors will furnish you with copies of the appropriate Form (and English translation if required as aforesaid) currently required to be filed in Canada pursuant to clause (b) of the first paragraph of this Section 9.14, if any, and in connection with the transfer of any Note the Guarantors will furnish the transferee of such Note with copies of any Form and English translation then required.

If any payment is made by a Guarantor to or for the account of the holder of any U.S. Dollar Note after deduction for or on account of any Taxes, and increased payments are made by such Guarantor pursuant to this Section 9.14, then, if such holder at its sole discretion determines that it has received or been granted a refund of such Taxes, such holder shall, to the extent that it can do so without prejudice to the retention of the amount of such refund, reimburse to such Guarantor such amount as such holder shall, in its sole discretion, determine to be attributable to the relevant Taxes or deduction or withholding. Nothing herein contained shall interfere with the right of the holder of any U.S. Dollar Note to arrange its tax affairs in whatever manner it thinks fit and, in particular, no holder of any U.S. Dollar Note shall be under any obligation to claim relief from its corporate profits or similar tax liability in respect of such Tax in priority to any other claims, reliefs, credits or deductions available to it or (other than as set forth in clause (b) above) oblige any holder of any U.S. Dollar Note to disclose any information relating to its tax affairs or any computations in respect thereof.

-19-

Each Guarantor will furnish the holders of U.S. Dollar Notes, promptly and in any event within 60 days after the date of any payment by a Guarantor of any Tax in respect of any amounts paid under this Agreement or the U.S. Dollar Notes, the original tax receipt issued by the relevant taxation or other authorities involved for all amounts paid as aforesaid (or if such original tax receipt is not available or must legally be kept in the possession of the Guarantors, a duly certified copy of the original tax receipt or any other reasonably satisfactory evidence of payment), together with such other documentary evidence with respect to such payments as may be reasonably requested from time to time by any holder of a Note.

If any Guarantor is required by any applicable law, as modified by the practice of the taxation or other authority of any relevant Taxing Jurisdiction, to make any deduction or withholding of any Tax in respect of which such Guarantor would be required to pay any additional amount under this Section 9.14, but for any reason does not make such deduction or withholding with the result that a liability in respect of such Tax is assessed directly against the holder of any U.S. Dollar Note, and such holder pays such liability, then such Guarantor will promptly reimburse such holder for such payment (including any related interest or penalties to the extent such interest or penalties arise by virtue of a default or delay by such Guarantor) upon demand by such holder accompanied by an official receipt (or a duly certified copy thereof) issued by the taxation or other authority of the relevant Taxing Jurisdiction.

If any Guarantor makes payment to or for the account of any holder of a U.S. Dollar Note and such holder is entitled to a refund of the Tax to which such payment is attributable upon the making of a filing (other than a Form described above), then such holder shall, as soon as practicable after receiving written request from such Guarantor (which shall specify in reasonable detail and supply the refund forms to be filed), use reasonable efforts to complete and deliver such refund forms to or as directed by such Guarantor, subject, however, to the same limitations with respect to Forms as are set forth above.

The obligations of the Guarantors under this Section 9.14 shall survive the payment or transfer of any U.S. Dollar Note and the provisions of this Section 9.14 shall also apply to successive transferees of the U.S. Dollar Notes.
