In addition

-10- SC1:3839600.5 to and without limitation of the foregoing, for purposes of this definition, “Consolidated Adjusted EBITDA” and “Consolidated Fixed Charges” shall be calculated after giving effect, on a Pro Forma Basis for the period of such calculation, to any Asset Sales or other dispositions or Asset Acquisitions, investments, mergers, amalgamations, consolidations and discontinued operations (as determined in accordance with IFRS) and designations of any Restricted Subsidiary to be an Unrestricted Subsidiary or any Unrestricted Subsidiary to be a Restricted Subsidiary occurring during the Four Quarter Period or any time subsequent to the last day of the Four Quarter Period and on or prior to the Transaction Date, as if such Asset Sale or other disposition or Asset Acquisition (including the Incurrence or assumption of any such Acquired Debt), investment, merger, amalgamation, consolidation, disposed operation or designation occurred on the first day of the Four Quarter Period. For purposes of this definition, Pro Forma calculations shall be made in accordance with Article 11 of Regulation S-X promulgated under the Securities Act or in accordance with Canadian Securities Laws. If the Debt which is the subject of a determination of the Consolidated Fixed Charge Coverage Ratio is Acquired Debt, or Debt Incurred in connection with the simultaneous Asset Acquisition, or Debt of an Unrestricted Subsidiary being designated as a Restricted Subsidiary, then such ratio shall be determined by giving effect (on a Pro Forma Basis, as if the transaction had occurred at the beginning of the Four Quarter Period) to (x) the Incurrence of such Acquired Debt or such other Debt by the Company or any of its Restricted Subsidiaries and (y) the inclusion, in Consolidated Adjusted EBITDA, of the Consolidated Adjusted EBITDA of the acquired Person, business, property or assets or redesignated Subsidiary. For purposes of calculating Debt which is the subject of a determination of the Consolidated Fixed Charge Coverage Ratio, the U.S. dollar equivalent principal amount of Debt denominated in another currency shall be calculated based on the relevant currency exchange rate in effect on the last day of the most recently ended fiscal quarter for which internal financial information is available at the time of calculation.

The Notes and any Additional Notes shall be substantially identical other than the issuance dates, offering price, and, if applicable, the date from which interest shall accrue. Except as described under Article 9, the Initial Notes and any Additional Notes subsequently issued under this Indenture will be treated as a single class for all purposes under this Indenture, including waivers, amendments, redemptions and offers to purchase, and shall vote together as one class on all matters with respect to the Notes, provided that if the Additional Notes are not fungible with the Notes for U.S. federal income tax purposes the Additional Notes will have a separate CUSIP number, if applicable. Unless the context requires otherwise, references to

-50- SC1:3839600.5 “Notes” for all purposes of this Indenture include any Additional Notes that are actually issued. Any Additional Notes shall be issued with the benefit of an indenture supplemental to this Indenture. In authenticating and delivering Additional Notes, the Trustee shall be entitled to receive and shall be fully protected in conclusively relying upon, in addition to the Opinion of Counsel and Officer’s Certificate required by Section 12.03, an Opinion of Counsel (i) as to the due authorization, execution, delivery, validity and enforceability of such Additional Notes, (ii) stating that the form and terms of such Additional Notes have been established by a supplemental indenture and pursuant to a resolution of the Board of Directors of the Company in conformity with the provisions of this Indenture and (iii) stating that all laws and requirements in respect of the execution and delivery by the Company of such Additional Notes have been complied with. (d) The provisions of the “Operating Procedures of the Euroclear System” and “Terms and Conditions Governing Use of Euroclear” and the “General Terms and Conditions of Clearstream Banking” and “Customer Handbook” of Clearstream shall be applicable to transfers of beneficial interests in the Regulation S Temporary Global Note and the Regulation S Permanent Global Note that are held by Participants through Euroclear or Clearstream. Section 2.02 Execution and Authentication. (a) At least one Authorized Officer shall execute the Notes on behalf of the Company by manual or facsimile signature. If an Authorized Officer whose signature is on a Note no longer holds that office at the time a Note is authenticated, the Note shall nevertheless be valid. (b) A Note shall not be entitled to any benefit under this Indenture or be valid or obligatory for any purpose until authenticated substantially in the form provided for in Exhibit A attached hereto by the manual signature of an authorized signatory of the Trustee. The signature shall be conclusive evidence that the Note has been duly authenticated and delivered under this Indenture. (c) On the Issue Date, the Trustee shall, upon receipt of a written order of the Company signed by an Authorized Officer (an “Authentication Order”), authenticate and deliver the Initial Notes. In addition, at any time and from time to time, the Trustee shall, upon receipt of an Authentication Order, authenticate and deliver any Additional Notes in an aggregate principal amount specified in such Authentication Order for such Additional Notes issued hereunder and, in the case of any issuance of Additional Notes pursuant to Section 2.01, such Authentication Order shall certify that such issuance is in compliance with Section 4.09. (d) The Trustee may appoint an authenticating agent acceptable to the Company to authenticate Notes. An authenticating agent may authenticate Notes whenever the Trustee may do so. Each reference in this Indenture to authentication by the Trustee includes authentication by such agent. An authenticating agent has the same rights as an Agent to deal with Holders or an Affiliate of the Company.

-51- SC1:3839600.5 Section 2.03 Registrar and Paying Agent. (a) The Company shall maintain an office or agency in the United States where Notes may be presented for registration of transfer or for exchange (“Registrar”) and at least one office or agency in the United States where Notes may be presented for payment (“Paying Agent”), which shall initially be the Corporate Trust Office of the Trustee located at 60 Livingston Avenue, St. Paul, Minnesota 55107. The Registrar shall keep a register of the Notes and of their transfer and exchange (“Note Register”). The Company may appoint one or more co-registrars and one or more additional paying agents. The term “Registrar” includes any co- registrar, and the term “Paying Agent” includes any additional paying agent. The Company may change any Paying Agent or Registrar without prior notice to any Holder; provided, however, that no such removal shall become effective until (i) acceptance of an appointment by a successor as evidenced by an appropriate agreement entered into by the Company and such successor Registrar or Paying Agent, as the case may be, and delivered to the Trustee and the passage of any waiting or notice periods required by the Depositary’s procedures or (ii) written notification to the Trustee that the Trustee shall serve as Registrar or Paying Agent until the appointment of a successor in accordance with clause (i) above. The Company shall enter into an appropriate agency agreement with any Registrar or Paying Agent not a party to this Indenture. The agreement shall implement the provisions of this Indenture that relate to such Agent. The Company shall notify the Trustee in writing of the name and address of any Agent not a party to this Indenture. If the Company fails to appoint or maintain another entity as Registrar or Paying Agent, the Trustee shall act as such and shall be entitled to appropriate compensation therefor pursuant to Section 7.07. The Company or any Affiliate incorporated or organized within the United States of America may act as Paying Agent (except for purposes of Article 8) or Registrar. (b) The Company initially appoints DTC to act as Depositary with respect to the Global Notes. The Company initially appoints the Trustee to act as Paying Agent and Registrar for the Notes, for which the Trustee shall be Custodian. If, at any time, the Trustee is not the Registrar, the Registrar shall make available to the Trustee ten days prior to each Interest Payment Date and at such other times as the Trustee may reasonably request the names and addresses of the Holders as they appear in the Note Register. Section 2.04 Paying Agent to Hold Money in Trust. The Company shall require each Paying Agent other than the Trustee to agree in writing that such Paying Agent shall hold in trust for the benefit of Holders or the Trustee all money held by such Paying Agent for the payment of principal, premium, if any, or interest, if any, on the Notes, and shall notify the Trustee of any default by the Company in making any such payment. While any such default continues, the Trustee may require a Paying Agent to pay all money held by it to the Trustee. The Company at any time may require a Paying Agent to pay all money held by it to the Trustee. Upon payment over to the Trustee, a Paying Agent (if other than the Company or a Subsidiary) shall have no further liability for the money. If the Company or an Affiliate of the Company acts as Paying Agent, it shall segregate and hold in a separate trust fund for the benefit of the Holders all money held by it as Paying Agent until such

-52- SC1:3839600.5 sum of money shall be paid to such Holders or otherwise disposed of as provided in this Indenture, and shall promptly notify the Trustee in writing of any action or failure to act as required by this Section. Upon any bankruptcy or reorganization proceedings relating to the Company, the Trustee shall serve as Paying Agent for the Notes. Section 2.05 Holder Lists. The Trustee shall preserve in as current a form as is reasonably practicable the most recent list available to it of the names and addresses of all Holders. If the Trustee is not the Registrar, the Company shall furnish to the Trustee in writing at least five Business Days before each Interest Payment Date and at such other times as the Trustee may reasonably request in writing, a list in such form and as of such date as the Trustee may reasonably require of the names and addresses of the Holders. Section 2.06 Transfer and Exchange. (a) Transfer and Exchange of Global Notes. Except as otherwise set forth in this Section 2.06, a Global Note may be transferred, in whole and not in part, only to another nominee of the Depositary or to a successor Depositary or a nominee of such successor Depositary. A beneficial interest in a Global Note may not be exchanged for a Definitive Note unless (i) the Depositary (x) notifies the Company that it is unwilling or unable to continue as Depositary for such Global Note or (y) has ceased to be a “clearing agency” registered under the Exchange Act and, in either case, a successor Depositary is not appointed by the Company within 90 days, (ii) there shall have occurred and be continuing a Default with respect to the Notes or (iii) the Company, at its option, notifies the Trustee in writing that it elects to cause the issuance of Definitive Notes (although Regulation S Temporary Global Notes at the Company’s election pursuant to this clause may not be exchanged for Definitive Notes prior to (a) the expiration of the Restricted Period and (b) the receipt of any certificates required under the provisions of Regulation S). Upon the occurrence of any of the preceding events in (i), (ii) or (iii) above, Definitive Notes delivered in exchange for any Global Note or beneficial interests therein will be registered in the names, and issued in any approved denominations, requested by or on behalf of the Depositary (in accordance with its customary procedures). Global Notes also may be exchanged or replaced, in whole or in part, as provided in Section 2.07 and Section 2.10. Every Note authenticated and delivered in exchange for, or in lieu of, a Global Note or any portion thereof, pursuant to this Section 2.06 or Section 2.07 or Section 2.10, shall be authenticated and delivered in the form of, and shall be, a Global Note, except for Definitive Notes issued subsequent to any of the preceding events in (i), (ii) or (iii) above and pursuant to Sections 2.06(c) or (e). A Global Note may not be exchanged for another Note other than as provided in this Section 2.06(a); provided, however, beneficial interests in a Global Note may be transferred and exchanged as provided in Sections 2.06(b) and (c). (b) Transfer and Exchange of Beneficial Interests in the Global Notes. The transfer and exchange of beneficial interests in the Global Notes shall be effected through the Depositary in accordance with the provisions of this Indenture and the Applicable Procedures. Beneficial interests in the Restricted Global Notes shall be subject to restrictions on transfer comparable to those set forth herein to the extent required by the Securities Act. Transfers of

-53- SC1:3839600.5 beneficial interests in the Global Notes also shall require compliance with either subparagraph (i), (ii), (iii) or (iv) below, as applicable, as well as one or more of the other following subparagraphs, as applicable: (i) Transfer of Beneficial Interests in the Same Global Note. Beneficial interests in any Restricted Global Note may be transferred to Persons who take delivery thereof in the form of a beneficial interest in the same Restricted Global Note in accordance with the transfer restrictions set forth in the Private Placement Legend; provided, however, that prior to the expiration of the Restricted Period, transfers of beneficial interests in the Regulation S Temporary Global Note may not be made to a U.S. Person or for the account or benefit of a U.S. Person (other than an Initial Purchaser). Beneficial interests in any Unrestricted Global Note may be transferred to Persons who take delivery thereof in the form of a beneficial interest in an Unrestricted Global Note. No written orders or instructions shall be required to be delivered to the Registrar to effect the transfers described in this Section 2.06(b)(i). (ii) All Other Transfers and Exchanges of Beneficial Interests in Global Notes. In connection with all transfers and exchanges of beneficial interests that are not subject to Section 2.06(b)(i), the transferor of such beneficial interest must deliver to the Registrar either (A) (1) a written order from a Participant or an Indirect Participant given to the Depositary in accordance with the Applicable Procedures directing the Depositary to credit or cause to be credited a beneficial interest in another Global Note in an amount equal to the beneficial interest to be transferred or exchanged and (2) instructions given in accordance with the Applicable Procedures containing information regarding the Participant account to be credited with such increase or (B) (1) a written order from a Participant or an Indirect Participant given to the Depositary in accordance with the Applicable Procedures directing the Depositary to cause to be issued a Definitive Note in an amount equal to the beneficial interest to be transferred or exchanged and (2) instructions given by the Depositary to the Registrar containing information regarding the Person in whose name such Definitive Note shall be registered to effect the transfer or exchange referred to in (B) (1) above; provided that in no event shall Definitive Notes be issued upon the transfer or exchange of beneficial interests in the Regulation S Temporary Global Note prior to (A) the expiration of the Restricted Period and (B) the receipt by the Registrar of any certificates required pursuant to Rule 903; provided, further, that in no event shall a beneficial interest in an Unrestricted Global Note be credited, or an Unrestricted Definitive Note be issued, to a Person who is an affiliate (as defined in Rule 144) of the Company. Upon satisfaction of all of the requirements for transfer or exchange of beneficial interests in Global Notes contained in this Indenture and the Notes or otherwise applicable under the Securities Act, the Trustee shall adjust the principal amount of the relevant Global Note(s) pursuant to Section 2.06(g).

-54- SC1:3839600.5 (iii) Transfer of Beneficial Interests to Another Restricted Global Note. A beneficial interest in any Restricted Global Note may be transferred to a Person who takes delivery thereof in the form of a beneficial interest in another Restricted Global Note if the transfer complies with the requirements of Section 2.06(b)(ii) and the Registrar receives the following: (A) if the transferee will take delivery in the form of a beneficial interest in the 144A Global Note, then the transferor must deliver a certificate in the form of Exhibit B hereto, including the certifications in item (1) thereof; or (B) if the transferee will take delivery in the form of a beneficial interest in the Regulation S Temporary Global Note or the Regulation S Permanent Global Note, then the transferor must deliver a certificate in the form of Exhibit B hereto, including the certifications in item (2) thereof.

A beneficial interest in any Restricted Global Note may be exchanged by any Holder thereof for a beneficial interest in an Unrestricted Global Note or transferred to a Person who takes delivery thereof in the form of a beneficial interest in an Unrestricted Global Note if the exchange or transfer complies with the requirements of Section 2.06(b)(ii) and: (A) the Registrar receives the following: (1) if the holder of such beneficial interest in a Restricted Global Note proposes to exchange such beneficial interest for a beneficial interest in an Unrestricted Global Note, a certificate from such Holder substantially in the form of Exhibit C hereto, including the certifications in item (1)(a) thereof; or (2) if the holder of such beneficial interest in a Restricted Global Note proposes to transfer such beneficial interest to a Person who shall take delivery thereof in the form of a beneficial interest in an Unrestricted Global Note, a certificate from such holder in the form of Exhibit B hereto, including the certifications in item (4) thereof; and, in each such case set forth in this subparagraph (A), if the Registrar so requests or if the Applicable Procedures so require, an Opinion of Counsel in form reasonably acceptable to the Registrar to the effect that such exchange or transfer is in compliance with the Securities Act and that the restrictions on transfer contained

-55- SC1:3839600.5 herein and in the Private Placement Legend are no longer required in order to maintain compliance with the Securities Act. If any such transfer is effected pursuant to subparagraph (A) above at a time when an Unrestricted Global Note has not yet been issued, the Company shall issue and, upon receipt of an Authentication Order in accordance with Section 2.02, the Trustee shall authenticate one or more Unrestricted Global Notes in an aggregate principal amount equal to the aggregate principal amount of beneficial interests transferred pursuant to subparagraph (A) above.

At any time prior to such cancellation, if any beneficial interest in a Global Note is exchanged for or transferred to a Person who will take delivery thereof in the form of a beneficial interest in another Global Note or for Definitive Notes, the principal amount of Notes

-64- SC1:3839600.5 represented by such Global Note shall be reduced accordingly, and an endorsement shall be made on such Global Note by the Trustee or by the Depositary at the direction of the Trustee to reflect such reduction.

(v) Neither the Company nor the Registrar shall be required (A) to issue, to register the transfer of, or to transfer or exchange any, Notes during a period of 15 days before a selection of Notes is to be redeemed under Section 3.02, (B) to register the transfer of or to exchange any Note so selected for redemption in whole or in part, except the unredeemed portion of any Note being redeemed in part, (C) to register the transfer of or to exchange a Note between a Record Date and the next succeeding Interest Payment Date or (D) to register the transfer of or to exchange a Note tendered and not withdrawn in connection with an Offer to Purchase.

Section 2.07 Replacement Notes. If any mutilated Note is surrendered to the Trustee or the Company and the Trustee receives evidence to its satisfaction of the ownership and destruction, loss or theft of any Note, the Company shall issue and the Trustee, upon receipt of an Authentication Order, shall authenticate a replacement Note if the Trustee’s requirements are met. An indemnity bond must be supplied by the Holder that is sufficient in the judgment of the Trustee and the Company to protect the Company, the Trustee, any Agent and any authenticating agent from any loss that any of them may suffer if a Note is replaced. The Company or the Trustee may charge for their expenses in replacing a Note, which may include any expenses of the Trustee. Every replacement Note is a contractual obligation of the Company and shall be entitled to all of the benefits of this Indenture equally and proportionately with all other Notes duly issued hereunder. Section 2.08 Outstanding Notes. (a) The Notes outstanding at any time are all the Notes that have been authenticated by the Trustee except for those canceled by it, those delivered to it for cancellation, those reductions in the interest in a Global Note effected by the Trustee in accordance with the provisions hereof, those described in this Section 2.08 as not outstanding and, solely to the extent provided for in Article 8, Notes that are subject to Legal Defeasance or Covenant Defeasance as provided in Article 8. Except as set forth in Section 2.09, a Note does not cease to be outstanding because the Company or an Affiliate of the Company holds the Note; provided that Notes held by the Company or a Subsidiary will not be deemed to be outstanding for purposes of Section 3.07(b). (b) If a Note is replaced or paid pursuant to Section 2.07, it ceases to be outstanding unless the Trustee receives proof satisfactory to it that the replaced Note is held by a protected purchaser, as such term is defined in Section 8-303 of the Uniform Commercial Code in effect in the State of New York. (c) If the principal amount of any Note is considered paid under Section 4.01, it ceases to be outstanding and interest on it ceases to accrue from and after the date of such payment.

-67- SC1:3839600.5 (d) If a Paying Agent (other than the Company, a Subsidiary or any Affiliate thereof) holds, on the maturity date or any redemption date or date for repurchase of the Notes money sufficient to pay Notes payable or to be redeemed or purchased on that date, then on and after that date such Notes shall be deemed to be no longer outstanding and shall cease to accrue interest. Section 2.09 Treasury Notes. In determining whether the Holders of the requisite principal amount of Notes have concurred in any direction, waiver or consent, Notes beneficially owned by the Company, or by any Affiliate of the Company, shall be considered as though not outstanding, except that for the purposes of determining whether the Trustee shall be protected in relying on any such direction, waiver or consent, only Notes that a Responsible Officer of the Trustee actually knows are so owned shall be so disregarded. Notes so owned that have been pledged in good faith shall not be disregarded if the pledgee establishes to the satisfaction of the Trustee the pledgee’s right to deliver any such direction, waiver or consent with respect to the Notes and that the pledgee is not the Company or any obligor under the Notes or any Affiliate of the Company or of such other obligor. Section 2.10 Temporary Notes. Until definitive Notes are ready for delivery, the Company may prepare and the Trustee, upon receipt of an Authentication Order, shall authenticate temporary Notes. Temporary Notes shall be substantially in the form of definitive Notes but may have variations that the Company considers appropriate for temporary Notes and as shall be reasonably acceptable to the Trustee. Without unreasonable delay, the Company shall prepare and the Trustee shall authenticate definitive Notes in exchange for temporary Notes upon surrender of such temporary Notes at the office or agency of the Company, without charge to the Holder. Until so exchanged, the Holders and beneficial holders, as the case may be, of temporary Notes shall be entitled to all of the benefits accorded to Holders, or beneficial holders, respectively, of Notes under this Indenture. Section 2.11 Cancellation. The Company at any time may deliver Notes to the Trustee for cancellation. The Registrar and Paying Agent shall forward to the Trustee any Notes surrendered to them for registration of transfer, exchange or payment. The Trustee or, at the direction of the Trustee, the Registrar or the Paying Agent and no one else shall cancel all Notes surrendered for registration of transfer, exchange, payment, replacement or cancellation and shall dispose of canceled Notes in accordance with its customary procedures (subject to the record retention requirement of the Exchange Act). Certification of the disposal of all canceled Notes shall, upon the written request of the Company, be delivered to the Company. The Trustee shall retain all canceled Notes in accordance with its standard procedures (subject to the record retention requirements of the Exchange Act), and copies of the canceled Notes shall be provided to the Company upon the Company’s written request. The Company may not issue new Notes to replace Notes that it has paid or that have been delivered to the Trustee for cancellation. If the Company acquires any of

-68- SC1:3839600.5 the Notes, such acquisition shall not operate as a redemption or satisfaction of Debt represented by such Notes unless or until the same are delivered to the Trustee for cancellation. The Trustee shall not authenticate Notes in place of canceled Notes other than pursuant to the terms of this Indenture. Section 2.12 Defaulted Interest. (a) If the Company defaults in a payment of interest on the Notes, it shall pay, or shall deposit with the Paying Agent money in immediately available funds sufficient to pay, the defaulted interest in any lawful manner plus, to the extent lawful, interest payable on the defaulted interest, to the Persons who are Holders on a subsequent special record date, in each case at the rate provided in the Notes and in Section 4.01. The Company shall notify the Trustee in writing of the amount of defaulted interest proposed to be paid on each Note and the date of the proposed payment, and at the same time the Company shall deposit with the Trustee an amount of money equal to the aggregate amount proposed to be paid in respect of such defaulted interest or shall make arrangements reasonably satisfactory to the Trustee for such deposit prior to the date of the proposed payment, such money when deposited to be held in trust for the benefit of the Persons entitled to such defaulted interest as provided in this Section 2.12. The Company shall fix or cause to be fixed each such special record date and payment date; provided that no such special record date shall be less than 10 days prior to the related payment date for such defaulted interest. At least 15 days before the special record date, the Company (or, upon the written request of the Company, the Trustee in the name and at the expense of the Company) shall send, or cause to be sent, to each Holder a notice that states the special record date, the related payment date and the amount of such interest to be paid. (b) Subject to the foregoing provisions of this Section 2.12 and for greater certainty, each Note delivered under this Indenture upon registration of transfer of or in exchange for or in lieu of any other Note shall carry the rights to interest accrued and unpaid, and to accrue interest, which were carried by such other Note. Section 2.13 Additional Amounts. (a) All payments made by or on behalf of the Company or any Guarantor (each such person who pays or credits such amounts, a “Payor”) under or with respect to the Notes or any Note Guarantee will be made free and clear of, and without deduction or withholding for, or on account of, any and all present or future income, stamp and other taxes, levies, imposts, duties, charges, fees, deductions or withholdings (hereinafter referred to as “taxes”) now or hereafter imposed, levied, collected, withheld or assessed by or on behalf of any jurisdiction in which such Payor is organized, resident or carrying on business for tax purposes or from or through which payments are made by or on behalf of such Payor or any political subdivision or authority of the foregoing that has the power to tax (each a “Taxing Jurisdiction”), unless the deduction or withholding is required by applicable law or by the interpretation or administration thereof by the relevant governmental authority. (b) At any time a relevant Taxing Jurisdiction requires deductions or withholdings of taxes from any payment made under or in respect of the Notes, the Payor will

-69- SC1:3839600.5 pay such additional amounts (“Additional Amounts”) as may be necessary so that the net amounts received by each Holder (including Additional Amounts), after such deduction or withholding (including withholding or deduction attributable to Additional Amounts payable hereunder), shall not be less than the amount the Holder would have received had no such deduction or withholding been required. (c) However, notwithstanding the foregoing, no Additional Amounts will be payable to a Holder of a Note by any Payor with respect to: (i) taxes that would not have been imposed but for the existence of any present or former connection between such Holder or beneficial owner (or between a fiduciary, settlor, beneficiary, partner, member or shareholder of the relevant Holder or beneficial owner, if the relevant Holder or beneficial owner is an estate, nominee, trust, partnership or corporation) and any Taxing Jurisdiction (including without limitation, by virtue of the Holder or beneficial owner being a citizen or resident of, incorporated in or carrying on a business, having a permanent establishment or having a place of business in such jurisdiction), other than solely by reason of the Holder or beneficial owner purchasing, holding or disposing of the Notes; (ii) taxes imposed on, or deducted or withheld from, payments in respect of the Notes if such payments could have been made without such imposition, deduction or withholding of such taxes had such Notes been presented for payment (where presentation is required) within 30 days after the relevant date (except to the extent that the Holder thereof would have been entitled to such Additional Amounts on presenting a Note for payment on the last day of such 30 day period); for this purpose, the “relevant date” in relation to any payments on any Note means: (a) the due date for payment thereof, or (b) if the full amount of the monies payable on such date have not been received by the Trustee on or prior to such due date, the date on which the full amount of such monies having been so received, provided that notice to that effect is duly given to Holders of the Notes in accordance with this Indenture; (iii) taxes imposed or withheld by reason of the failure by the Holder or beneficial owner of such Note to provide certification, information, documents or other evidence concerning the nationality, residence or identity of the Holder or beneficial owner or to make any declaration or similar claim or satisfy any other reporting requirement relating to such matters, within 30 days after a specific written request therefor from a Payor, which is required by law, regulation or administrative practice or applicable treaty as a precondition to exemption from or reduction in the rate of deduction or withholding of all or part of such taxes; (iv) withholding tax payable under Part XIII of the Income Tax Act (Canada) (the “Tax Act”) that is imposed on amounts payable to or for the account of a beneficial owner of a Note as a consequence of such beneficial owner not dealing at arm’s length (within the meaning of the Tax Act) with a Payor at the time of such payment; (v) any withholding tax payable under Part XIII of the Tax Act that is imposed on amounts payable to or for the account of a beneficial owner of a Note as a consequence of such beneficial owner being, at any time, a “specified non-resident shareholder” (within the meaning of subsection 18(5) of the Tax Act) of the Company, or, at any time, not dealing at arm’s length (within the meaning of the Tax Act) with a “specified shareholder” (within the meaning of subsection 18(5) of the Tax Act) of the Company; (vi) any estate, inheritance, gift , sales, transfer or similar tax; (vii) any tax or penalty arising from the Holder’s failure to properly comply with the Holder’s obligations imposed under Part XVIII of the Tax Act or the similar provisions of legislation of any other jurisdiction that has entered into an agreement with the United States of America to provide for the implementation of reporting in that jurisdiction in

-70- SC1:3839600.5 compliance with Sections 1471 through 1474 of the U.S. Internal Revenue Code of 1986, as amended (the “Code”); or (viii) taxes arising from any combination of the foregoing clauses (i) to (vii). (d) The Payors will (1) make such withholding or deduction and (2) remit the full amount deducted or withheld to the relevant government authority in accordance with applicable law. The Payors will furnish to the Trustee, within 30 days after the date the payment of any taxes is due pursuant to applicable law, certified copies of tax receipts evidencing that such payment has been made or other evidence of such payment satisfactory to the Trustee. (e) The Payors, jointly and severally, will indemnify and hold harmless each Holder and beneficial owner of Notes and upon written request reimburse each such Holder and beneficial owner for the amount of (x) any taxes so levied or imposed and paid by such Holder or beneficial owner (including, for greater certainty, taxes imposed and paid pursuant to subsection 215(4) of the Tax Act and section 803 of the Income Tax Regulations (Canada) or any successor provision) as a result of payments made under or with respect to the Notes, (y) any liability (including penalties, interest, additions to tax and reasonable expenses) arising therefrom or with respect thereto, and (z) any taxes levied or imposed and paid by such Holder or beneficial owner with respect to any reimbursement under (x) or (y) above; provided, however, that the indemnification or reimbursement obligations provided for in this Section 2.13(e) shall not extend to taxes for which the applicable Holder would not have been eligible to receive payment of Additional Amounts hereunder by virtue of clauses (i) through (viii) of Section 2.13(c) if the Payor had been required to withhold from such payments or to the extent such Holder received Additional Amounts with respect to such payments. (f) In addition, any amounts to be paid by a Payor on the Notes will be paid net of any deduction or withholding imposed or required pursuant to Sections 1471 through 1474 of the Code, any current or future regulations or official interpretations thereof, any agreement entered into pursuant to Section 1471(b) of the Code, or any fiscal or regulatory legislation, rules or practices adopted pursuant to any intergovernmental agreement entered into in connection with the implementation of such Sections of the Code (“FATCA Withholding”). Neither any Guarantor nor the Company will be required to pay Additional Amounts on account of any FATCA Withholding. (g) Each Holder entitled to any Additional Amounts shall cooperate, to the extent described in clause (iii) of Section 2.13(c) above, with the Company and the Trustee in providing any information or documentation that is required by applicable law or by the taxing authority of the relevant Taxing Jurisdiction and that is reasonably requested in writing by the Company or the Trustee to confirm the identity and/or tax status of such Holder and any affected beneficial owner and to assist the Company or Trustee in determining the applicable withholding tax rate and the amount of Additional Amounts payable in respect thereof. (h) At least 30 calendar days prior to each date on which any payment under or with respect to the Notes or any Note Guarantee is due and payable, if a Payor will be obligated to pay Additional Amounts with respect to such payment, the Company will deliver to the Trustee an Officer’s Certificate stating that such Additional Amounts will be payable and the

-71- SC1:3839600.5 amounts so payable, and will set forth such other information necessary to enable the Trustee to pay such Additional Amounts to Holders on the payment date net of any taxes required to be withheld or deducted. (i) In addition, the Payor will pay any stamp, issue, registration, court, documentation, excise or other similar taxes, charges and duties, including any interest, penalties and any similar liabilities with respect thereto, imposed by any Taxing Jurisdiction at any time in respect of the execution, issuance, registration or delivery of the Notes, any Note Guarantee, this Indenture or any other document or instrument referred to hereunder or thereunder and any such taxes, charges or duties imposed by a Taxing Jurisdiction on any payments made pursuant to the Notes or as a result of, or in connection with, the enforcement of the Notes, any Note Guarantee and/or any other such document or instrument. (j) The obligations under this Section 2.13 will survive any termination, defeasance or discharge of this Indenture and will apply mutatis mutandis to any successor Person to the Payor and to any jurisdiction in which such successor is organized or is otherwise resident or carrying on business for tax purposes or any jurisdiction from or through which payment is made by such successor or its respective agents. (k) Whenever this Indenture refers to, in any context, the payment of principal, premium, if any, interest or any other amount payable under or with respect to any Note or any Note Guarantee, such reference shall be deemed to include the payment of Additional Amounts or indemnification payments as described in this Section 2.13, to the extent that, in such context, Additional Amounts are, were or would be payable in respect thereof. Section 2.14 CUSIP and ISIN Numbers. The Company in issuing the Notes may use CUSIP or ISIN numbers (if then generally in use) and if it does, the Trustee shall use CUSIP or ISIN numbers in notices of redemption or exchange or in Offers to Purchase as a convenience to Holders; provided that any such notice may state that no representation is made as to the correctness of such numbers either as printed on the Notes or as contained in any notice of redemption or exchange or in Offers to Purchase and that reliance may be placed only on the other identification numbers printed on the Notes, and any such redemption or exchange or Offer to Purchase shall not be affected by any defect in or omission of such numbers. The Company shall promptly notify the Trustee in writing of any change in the CUSIP or ISIN numbers. Section 2.15 Computation of Interest. (a) Interest shall be computed on the basis of a 360-day year comprised of twelve 30-day months. (b) For purposes of the Interest Act (Canada), whenever any interest or fee under the Notes or this Indenture is calculated using a rate based on a number of days less than a full year, such rate determined pursuant to such calculation, when expressed as an annual rate, is equivalent to (x) the applicable rate, (y) multiplied by the actual number of days in the relevant

-72- SC1:3839600.5 year of calculation, and (z) divided by the number of days based on which such rate is calculated. The principle of deemed reinvestment of interest does not apply to any interest calculation under the Notes or this Indenture. The rates of interest stipulated in the Notes and this Indenture are intended to be nominal rates and not effective rates or yields. ARTICLE 3 REDEMPTION Section 3.01 Notices to Trustee. If the Company elects to redeem Notes pursuant to Section 3.07 or Section 3.09, it shall furnish to the Trustee, at least five Business Days before notice of redemption is required to be sent or caused to be sent to Holders pursuant to Section 3.03 (unless a shorter notice shall be agreed to by the Trustee in writing) but not more than 60 days before a redemption date, an Officer’s Certificate setting forth (1) the paragraph or subparagraph of such Note or Section of this Indenture pursuant to which the redemption shall occur, (2) the redemption date, (3) the principal amount of the Notes to be redeemed and (4) the redemption price, if then ascertainable. Section 3.02 Selection of Notes to Be Redeemed or Purchased. (a) If less than all of the Notes are to be redeemed pursuant to Section 3.07 or purchased in an Offer to Purchase at any time, the Trustee shall select the Notes to be redeemed or purchased (1) if the Notes are listed on any national securities exchange, in compliance with the requirements of the principal national securities exchange on which the Notes are listed or (2) if the Notes are not so listed, on a pro rata basis, by lot or by such other method as the Trustee in its sole discretion shall deem fair and appropriate, all in accordance with the procedures of the Depositary in the case of Global Notes. In the event of partial redemption or purchase by lot, the particular Notes to be redeemed or purchased shall be selected, unless otherwise provided herein, not less than 30 nor more than 60 days prior to the redemption date by the Trustee from the then outstanding Notes not previously called for redemption or purchase. (b) The Trustee shall promptly notify the Company in writing of the Notes selected for redemption or purchase and, in the case of any Note selected for partial redemption or purchase, the principal amount thereof to be redeemed or purchased. Notes and portions of Notes selected shall be in amounts of $1,000 or whole number multiples of $1,000; no Notes of $2,000 or less shall be redeemed in part, except that if all of the Notes of a Holder are to be redeemed or purchased, the entire outstanding amount of Notes held by such Holder, even if not $2,000 or a multiple of $1,000 in excess thereof, shall be redeemed or purchased. Except as provided in the preceding sentence, provisions of this Indenture that apply to Notes called for redemption or purchase also apply to portions of Notes called for redemption or purchase. (c) After the redemption date, upon surrender of a Note to be redeemed in part only, a new Note or Notes in principal amount equal to the unredeemed portion of the original Note, representing the same Debt to the extent not redeemed, shall be issued in the name of the

-73- SC1:3839600.5 Holder of the Notes upon cancellation of the original Note (or appropriate book entries shall be made to reflect such partial redemption). Section 3.03 Notice of Redemption. (a) The Company shall send, or cause to be sent (in the case of Notes held in book-entry form, by electronic transmission) notices of redemption of Notes at least 30 days but not more than 60 days before the redemption date to each Holder whose Notes are to be redeemed pursuant to this Article at such Holder’s registered address or otherwise in accordance with the Applicable Procedures of the Depositary, except that redemption notices may be sent more than 60 days prior to a redemption date if the notice is issued in connection with Article 8 or Article 11. (b) The notice shall identify the Notes to be redeemed (including CUSIP and ISIN number, if applicable) and shall state: (1) the redemption date; (2) the redemption price, including the portion thereof representing any accrued and unpaid interest, if any; provided that in connection with a redemption under Section 3.07(a), the notice need not set forth the redemption price but only the manner of calculation thereof; (3) if any Note is to be redeemed in part only, the portion of the principal amount of that Note that is to be redeemed; (4) the name and address of the Paying Agent; (5) that Notes called for redemption must be surrendered to the Paying Agent to collect the redemption price; (6) that, unless the Company defaults in making such redemption payment or the Paying Agent is prohibited from making such payment pursuant to the terms of this Indenture, interest on Notes called for redemption ceases to accrue on and after the redemption date; (7) the paragraph or subparagraph of the Notes or Section of this Indenture pursuant to which the Notes called for redemption are being redeemed; and (8) that no representation is made as to the correctness or accuracy of the CUSIP or ISIN number, if any, listed in such notice or printed on the Notes. (c) At the Company’s request, the Trustee shall give the notice of redemption in the Company’s name and at the Company’s expense; provided that the Company shall have delivered to the Trustee, at least five Business Days before notice of redemption is required to be sent or caused to be sent to Holders pursuant to this Section 3.03 (unless a shorter notice shall be

-74- SC1:3839600.5 agreed to by the Trustee), an Officer’s Certificate requesting that the Trustee give such notice and setting forth the information to be stated in such notice as provided in Section 3.03(b). Section 3.04 Effect of Notice of Redemption. Once notice of redemption is sent in accordance with Section 3.03, Notes called for redemption become irrevocably due and payable on the redemption date at the redemption price. The notice, if sent in a manner herein provided, shall be conclusively presumed to have been given, whether or not the Holder receives such notice. In any case, failure to give such notice or any defect in the notice to the Holder of any Note designated for redemption in whole or in part shall not affect the validity of the proceedings for the redemption of any other Note. Subject to Section 3.05, on and after the redemption date, interest ceases to accrue on Notes or portions of Notes called for redemption. Section 3.05 Deposit of Redemption or Purchase Price. (a) By no later than 11:00 a.m. (New York City time) on the redemption or purchase date, the Company shall deposit with the Trustee or with the Paying Agent money sufficient to pay the redemption or purchase price of and accrued and unpaid interest, if any, on all Notes to be redeemed or purchased on that date. The Paying Agent shall promptly mail to each Holder whose Notes are to be redeemed or repurchased the applicable redemption or purchase price thereof and accrued and unpaid interest, if any, thereon. The Trustee or the Paying Agent shall promptly return to the Company any money deposited with the Trustee or the Paying Agent by the Company in excess of the amounts necessary to pay the redemption or purchase price of, and accrued and unpaid interest, if any, on, all Notes to be redeemed or purchased.

(b) However, the preceding provisions shall not prohibit the following encumbrances or restrictions existing under or by reason of: (1) any encumbrance or restriction in existence on the Issue Date, including those under the Credit Agreement, and any amendments, modifications, restatements, renewals, increases, supplements, refundings, replacements or refinancings thereof; provided that the amendments, modifications, restatements, renewals, increases, supplements, refundings, replacements or refinancings, in the good faith judgment of the Company and conclusively evidenced by an Officer’s Certificate, are no more restrictive in any material respect, taken as a whole, with respect to such dividend or other payment restrictions than those contained in these agreements on the Issue Date or refinancings thereof; (2) any encumbrance or restriction which exists with respect to an acquired property in existence at the time of such acquisition pursuant to an agreement, so long as the encumbrances or restrictions in any such agreement relate solely to the property so acquired (and are not or were not created in anticipation of or in connection with the acquisition thereof); (3) any encumbrance or restriction which exists with respect to a Person that becomes a Restricted Subsidiary or merges or amalgamates with or into a Restricted Subsidiary of the Company on or after the Issue Date, which is in existence at the time such Person becomes a Restricted Subsidiary, but not created in connection with or in anticipation of such Person becoming a Restricted Subsidiary, and which is not applicable to any Person or the property or assets of any Person other than such Person or the property or assets of such Person becoming a Restricted Subsidiary; (4) any encumbrance or restriction under the terms of Refinancing Debt Incurred to renew, refund, replace, refinance or extend any agreement containing any encumbrance or restriction referred to in the foregoing clauses (1) through (3), so long as the encumbrances and restrictions contained in any such Refinancing Debt are no less favorable in any material respect to the Holders than the encumbrances and restrictions contained in the agreements governing the Debt being renewed, refunded,

-87- SC1:3839600.5 replaced, refinanced, or extended, in the good faith judgment of the Company and conclusively evidenced by an Officer’s Certificate; (5) customary provisions restricting subletting or assignment of any lease, contract, or license of the Company or any Restricted Subsidiary or any rights thereunder; (6) any encumbrance or restriction by reason of applicable law, rule, regulation or order; (7) any encumbrance or restriction under this Indenture, the Notes and the Note Guarantees; (8) any encumbrance or restriction under a contract for the sale or other disposition of assets or Capital Interests, including, without limitation, any agreement for the sale or other disposition of a Subsidiary, that restricts distributions of the applicable assets or Capital Interests to be issued or sold, or of any assets of a Subsidiary to be sold, pending such sale or other disposition; (9) restrictions on cash and other deposits or net worth imposed by customers under contracts entered into in the ordinary course of business; (10) customary provisions with respect to the disposition or distribution of property or assets in joint venture agreements, asset sale agreements, stock sale agreements (including underwriting agreements), sale leaseback agreements and other similar agreements; (11) any restriction with respect to the Company or a Restricted Subsidiary (or any of its property or assets) imposed by customary provisions in Hedging Obligations or Swap Contracts, in each case, not entered into for speculative purposes; (12) Purchase Money Debt and Capital Lease Obligations permitted under this Indenture for property acquired in the ordinary course of business that impose restrictions on that property so acquired of the nature described in Section 4.08(a)(3); (13) Liens securing Debt otherwise permitted to be Incurred under this Indenture, including Section 4.12; and (14) any other agreement governing Debt entered into after the Issue Date that contains encumbrances and restrictions that are not materially more restrictive with respect to any Restricted Subsidiary than those in effect on the Issue Date with respect to that Restricted Subsidiary pursuant to agreements in effect on the Issue Date. (c) Nothing contained in this Section 4.08 shall prevent the Company or any Restricted Subsidiary from (i) creating, Incurring, assuming or suffering to exist any Liens otherwise permitted by Section 4.12 or (ii) restricting the sale or other disposition of property or

-88- SC1:3839600.5 assets of the Company or any of its Restricted Subsidiaries that secure Debt of the Company or any of its Restricted Subsidiaries Incurred in accordance with Section 4.09 and Section 4.12. Section 4.09 Incurrence of Debt. (a) The Company will not, and will not permit any of its Restricted Subsidiaries to Incur any Debt (including Acquired Debt); provided, that the Company and any of its Restricted Subsidiaries may Incur Debt (including Acquired Debt) if, immediately after giving effect to the Incurrence of such Debt and the receipt and application of the proceeds therefrom: (1) the Consolidated Fixed Charge Coverage Ratio of the Company and its Restricted Subsidiaries, determined on a Pro Forma Basis, including as if any such Debt (including any other Debt being Incurred contemporaneously), and any other Debt Incurred since the beginning of the Four Quarter Period had been Incurred and the proceeds thereof had been applied at the beginning of the Four Quarter Period, and any other Debt repaid since the beginning of the Four Quarter Period had been repaid at the beginning of the Four Quarter Period, would be greater than 2.00 to 1.00; and (2) no Event of Default shall have occurred and be continuing at the time or as a consequence of the Incurrence of such Debt. (b) Notwithstanding Section 4.09(a), the Company and its Restricted Subsidiaries may Incur Permitted Debt. (c) For purposes of determining compliance with this Section 4.09: (1) in the event that an item of Debt meets the criteria of more than one of the types of Debt described in Section 4.09(a) or (b), including categories of Permitted Debt, the Company, in its sole discretion, shall classify, and from time to time may reclassify, all or any portion of such item of Debt in any manner that complies with Section 4.09 and shall only be required to include the amount and type of such Debt in one of such clauses under Section 4.09 or the definition of “Permitted Debt” hereunder; provided that any Debt outstanding on the Issue Date under any Credit Facility shall at all times be treated as Incurred on the Issue Date pursuant to clause (1) of the definition of “Permitted Debt” hereunder; (2) Debt permitted by this Section 4.09 need not be permitted solely by reference to one provision permitting such Debt but may be permitted in part by one such provision and in part by one or more other provisions of this Section 4.09 (including categories of Permitted Debt) permitting such Debt; and (3) Guarantees of, or obligations with respect to letters of credit supporting, Debt that is otherwise included in the determination of a particular amount of Debt shall not be included.

-89- SC1:3839600.5 The accrual of interest, the accretion or amortization of original issue discount and the payment of interest on Debt in the form of additional Debt or payment of dividends on Capital Interests in the forms of additional shares of Capital Interests with the same terms will not be deemed to be an Incurrence of Debt for purposes of this Section 4.09. For purposes of determining compliance with any U.S. dollar-denominated restriction on the Incurrence of Debt, the U.S. dollar-equivalent principal amount of Debt denominated in another currency shall be calculated based on the relevant currency exchange rate in effect on the date such Debt was Incurred, in the case of term Debt, or first committed, in the case of revolving credit Debt; provided that if such Debt is Incurred as Refinancing Debt to refinance Debt denominated in another currency, and such refinancing would cause the applicable U.S. dollar-denominated restriction to be exceeded if calculated at the relevant currency exchange rate in effect on the date of such refinancing, such U.S. dollar-denominated restriction shall be deemed not to have been exceeded so long as the principal amount of such Refinancing Debt does not exceed (i) the principal amount of such Debt being refinanced, plus (ii) the aggregate amount of fees, underwriting discounts, defeasance costs, premiums and other costs and expenses Incurred in connection with such refinancing. Notwithstanding any other provision of this covenant, the maximum amount of Debt that the Company may Incur pursuant to this covenant shall not be deemed to be exceeded solely as a result of fluctuations in the exchange rate of currencies. Section 4.10 Asset Sales. (a) The Company will not, and will not permit any of its Restricted Subsidiaries to, consummate an Asset Sale unless: (1) the Company or such Restricted Subsidiary, as the case may be, receives consideration at the time of the Asset Sale at least equal to the Fair Market Value (such Fair Market Value to be determined at the time of contractually agreeing to such Asset Sale) of the assets or Capital Interests issued or sold or otherwise disposed of; and (2) at least 75% of the consideration received in the Asset Sale by the Company or such Restricted Subsidiary, as the case may be, is in the form of cash or Eligible Cash Equivalents. (b) For the purposes of Section 4.10(a)(2) above, each of the following will be deemed to be cash: (1) any liabilities (as shown on the most recent consolidated balance sheet of the Company or any Restricted Subsidiary) of the Company or any of its Restricted Subsidiaries (other than contingent liabilities and liabilities that are by their terms subordinated to the Notes or any Note Guarantee) that are assumed by the transferee of any such assets pursuant to a customary assignment and assumption agreement that releases the Company or such Restricted Subsidiary from further liability;

-90- SC1:3839600.5 (2) any securities, notes or other obligations received by the Company or any of its Restricted Subsidiaries from the transferee that are converted by the Company or such Restricted Subsidiary into cash within 180 days of their receipt to the extent of the cash received in that conversion; (3) any Designated Non-cash Consideration received by the Company or any of its Restricted Subsidiaries in such Asset Sale having an aggregate Fair Market Value, taken together with all other Designated Non-cash Consideration received pursuant to this clause (3) that is at that time outstanding, not to exceed 2.0% of Consolidated Total Assets at the time of the receipt of such Designated Non-cash Consideration (with the Fair Market Value of each item of Designated Non-cash Consideration being measured at the time received and without giving effect to subsequent changes in value); and (4) any Investment, stock, asset, property or capital expenditure of the kind referred to in clauses (3), (4), (5) or (6) of Section 4.10(c). (c) Within 365 days after the receipt of any Net Cash Proceeds from an Asset Sale (the “Asset Sale Proceeds Application Period”), the Company or the applicable Restricted Subsidiary, as the case may be, may apply such Net Cash Proceeds, at its option: (1) to prepay, repay, redeem or purchase any Secured Debt (other than Subordinated Obligations) of the Company or any Restricted Subsidiary and cause such Debt to be permanently retired and the related commitment (if any) to be permanently reduced in an amount equal to the principal amount so prepaid, repaid, redeemed or repurchased; (2) to prepay, repay, redeem or purchase any unsecured Debt (other than Subordinated Obligations) of the Company or any Restricted Subsidiary and cause such Debt to be permanently retired and the related commitment (if any) to be permanently reduced in an amount equal to the principal amount so prepaid, repaid, redeemed or repurchased; provided that to the extent the Company (or the applicable Restricted Subsidiary, as the case may be) repays any such Debt other than the Notes, the Company shall offer to purchase an equal and ratable amount of the Notes as provided under Article 3 by making an Offer to Purchase (in accordance with the procedures set forth in Section 4.10(d)) to all Holders of Notes to purchase their Notes at 100% of the principal amount thereof, plus accrued but unpaid interest to, but not including, the date of purchase, if any; (3) to acquire all or substantially all of the assets of, or any Capital Interests of, another Permitted Business, if, after giving effect to any such acquisition of Capital Interests, the Permitted Business is or becomes a Restricted Subsidiary of the Company; (4) to make a capital expenditure in or that is used or useful (as determined in the good faith judgment of the Company) in a Permitted Business or to

-91- SC1:3839600.5 make expenditures for maintenance, repair or improvement of existing properties and assets in accordance with the provisions of this Indenture; (5) to acquire other assets that are not classified as current assets under IFRS and that are used or useful (as determined in the good faith judgment of the Company) in a Permitted Business; or (6) any combination of the foregoing, provided that, in the case of clause (4) of this Section 4.10(c), a binding commitment shall be treated as a permitted application of the Net Cash Proceeds from the date of such commitment so long as the Company or such Restricted Subsidiary enters into such commitment with the good faith expectation that such Net Cash Proceeds will be applied to satisfy such commitment within 180 days of the Asset Sale Proceeds Application Period (an “Acceptable Commitment”) and such Net Cash Proceeds are actually applied in such manner within the later of 365 days from the consummation of the Asset Sale and 180 days from the date of the Acceptable Commitment, and, in the event any Acceptable Commitment is later cancelled or terminated for any reason before the Net Cash Proceeds are applied in connection therewith, then such Net Cash Proceeds shall constitute Excess Proceeds to the extent the Asset Sale Proceeds Application Period has expired. (d) Any Net Cash Proceeds from Asset Sales that are not applied or invested as provided in Section 4.10(c) will constitute “Excess Proceeds.” When the aggregate amount of Excess Proceeds exceeds the greater of (x) $25 million and (y) 1.0% of Consolidated Total Assets, the Company will, within 30 days after the expiry of the Asset Sale Proceeds Application Period, make an Offer to Purchase to all Holders of Notes (on a pro rata basis to each series of Notes), and to all holders of other Debt ranking pari passu with the Notes containing provisions similar to those set forth in this Indenture with respect to assets sales, in an amount equal to the Excess Proceeds. The offer price in any Offer to Purchase will be equal to 100% of the principal amount plus accrued and unpaid interest, if any, to, but not including, the date of purchase, and will be payable in cash. If any Excess Proceeds remain after consummation of an Offer to Purchase, the Company may use those funds for any purpose not otherwise prohibited by this Indenture and such remaining Excess Proceeds will no longer constitute Excess Proceeds. If the aggregate principal amount of Notes and other pari passu Debt tendered into such Offer to Purchase exceeds the amount of Excess Proceeds, the Trustee will select the Notes to be purchased on a pro rata basis among each series. Upon completion of each Offer to Purchase, the amount of Excess Proceeds will be reset at zero. (e) Pending the final application of any Net Cash Proceeds pursuant to this Section 4.10, such Net Cash Proceeds may be applied temporarily to reduce Debt outstanding under a revolving credit facility or may otherwise be invested in any manner not prohibited by this Indenture. (f) The Company will comply with the applicable requirements of Rule 14e-1 under the Exchange Act and any other applicable securities laws and regulations thereunder, including Canadian Securities Laws, to the extent those laws and regulations are applicable in

-92- SC1:3839600.5 connection with each repurchase of Notes pursuant to an Offer to Purchase. To the extent that the provisions of any securities laws or regulations conflict with the provisions of this Indenture, the Company will comply with the applicable securities laws and regulations and will be deemed to have complied with its obligations under the provisions of this Section 4.10 by virtue of such compliance with the applicable securities laws and regulations. (g) Other than as specifically provided in this Section 4.10, any purchase pursuant to this Section 4.10 shall be made pursuant to the provisions of Sections 3.02, 3.05 and 3.06. Section 4.11 Transactions with Affiliates. (a) The Company will not, and will not permit any of its Restricted Subsidiaries to, directly or indirectly, make any payment to, or sell, lease, transfer or otherwise dispose of any of its properties or assets to, or purchase any property or assets from, or enter into or make or amend any transaction (or series of related transactions), contract, agreement, loan, advance or Guarantee with, or for the benefit of, any Affiliate of the Company involving aggregate consideration in excess of $2.5 million (each of the foregoing, an “Affiliate Transaction”), unless: (1) such Affiliate Transaction is on terms that are not materially less favorable to the Company or the relevant Subsidiary than those that could reasonably have been obtained in a comparable arm’s length transaction by the Company or such Subsidiary with a Person who is not an Affiliate; and (2) with respect to any Affiliate Transaction or series of related Affiliate Transactions involving an aggregate consideration in excess of $10 million, the Company delivers to the Trustee a resolution adopted in good faith by the majority of the Board of Directors of the Company approving such Affiliate Transaction and set forth in an Officer’s Certificate certifying that such Affiliate Transaction complies with clause (1) above. (b) Section 4.11(a) shall not apply to: (1) any Restricted Payment permitted to be made pursuant to Section 4.07 and any Permitted Investments (other than a Permitted Investment described in clause (6) of the definition thereof); (2) the payment of reasonable and customary fees and other benefits and indemnities to officers, consultants, employees of the Company or a Restricted Subsidiary, and members of the Board of Directors of the Company or a Restricted Subsidiary who are outside directors; (3) the payment of reasonable and customary compensation and other benefits (including retirement, health, option, deferred compensation and other benefit plans, and annual retainer fees for directors (or a duly authorized committee thereof)) and

-93- SC1:3839600.5 indemnities to directors, officers and employees of the Company or any Restricted Subsidiary as determined by the Board of Directors thereof in good faith; (4) transactions between or among the Company and/or its Restricted Subsidiaries; (5) any agreement or arrangement as in effect on the Issue Date and any amendment or modification thereto so long as such amendment or modification is no less favorable in any material respect to the Holders; (6) any contribution of capital to the Company or a Restricted Subsidiary; (7) transactions permitted by, and complying with, the provisions of Section 5.01; (8) any transaction with a joint venture, partnership, limited liability company or other entity (other than an Unrestricted Subsidiary) that would constitute an Affiliate Transaction solely because the Company or a Restricted Subsidiary owns an equity interest in such joint venture, partnership, limited liability company or other entity; (9) transactions with customers, distributors, clients, suppliers or purchasers or sellers of goods or services, in each case, in the ordinary course of business and on terms that are not materially less favorable to the Company or such Restricted Subsidiary, as the case may be, as determined in good faith by the Company, than those that could be obtained in a comparable arm’s length transaction with a Person that is not an Affiliate of the Company; (10) any issuance of securities, or other payments, awards or grants in cash, securities or otherwise pursuant to, or the funding of, employment arrangements, equity purchase agreements, stock options, long term incentive plans and stock ownership plans approved by the Board of Directors of the Company; (11) any purchase of Capital Interests (other than Redeemable Capital Interests) of the Company or a Restricted Subsidiary or any contribution to the equity capital of the Company or a Restricted Subsidiary; (12) (i) payments by the Company and any of its Restricted Subsidiaries pursuant to any tax sharing agreements among any of a Parent Entity, the Company and any of its Restricted Subsidiaries on customary terms that require each party to make payments when taxes are due or refunds received of amounts equal to the income tax liabilities and refunds generated by each such party and (ii) payments by any Parent Entity, the Company or any of its Restricted Subsidiaries pursuant to any tax sharing agreements among such Parent Entity, the Company and any of its Restricted Subsidiaries on customary terms that require each party to make payments when taxes are due or refunds received of amounts equal to the income tax liabilities and refunds

-94- SC1:3839600.5 generated by each such party calculated on a separate return basis, and payments to the party generating tax benefits and credits of amounts equal to the value of such tax benefits and credits made available to the party making the payments; and (13) transactions in which the Company or any Restricted Subsidiary, as the case may be, delivers to the Trustee a letter from a nationally recognized investment bank or accounting or appraisal firm stating substantially to the effect that such transaction is fair to the Company or such Restricted Subsidiary from a financial point of view or stating that the terms are not materially less favorable to the Company or such Restricted Subsidiary than those that would have been obtained in a comparable transaction by the Company or such Restricted Subsidiary with an unrelated Person on an arm’s length basis. Section 4.12 Liens. The Company will not, and will not permit any of its Restricted Subsidiaries to, create, Incur, assume or otherwise cause or suffer to exist or become effective any Lien of any kind securing Debt (other than Permitted Liens) upon any of their property or assets, whether owned on the Issue Date or acquired thereafter, unless, contemporaneously with the Incurrence of such Liens, all payments due under this Indenture and the Notes are secured on an equal and ratable basis with the obligations so secured (or in the case of Subordinated Obligations, prior or senior thereto, with the same relative priority as the Notes shall have with respect to such Subordinated Obligations) until such time as such obligations are no longer secured by a Lien. Any Lien created for the benefit of Holders pursuant to this Section 4.12 shall be automatically and unconditionally released and discharged upon the release and discharge of the Lien that gave rise to the obligation to secure the payments due under this Indenture and the Notes. Section 4.13 Corporate Existence. Subject to Article 5, the Company shall do or cause to be done all things necessary to preserve and keep in full force and effect (1) its corporate existence and the corporate, partnership, limited liability company or other existence of each of its Restricted Subsidiaries, in accordance with the respective organizational documents (as the same may be amended from time to time) of the Company or any such Restricted Subsidiary and (2) the material rights, licenses and franchises of the Company and its Restricted Subsidiaries; provided that the Company shall not be required to preserve any such right, license or franchise, or the corporate, partnership, limited liability company or other existence of any of its Restricted Subsidiaries, if the Company in good faith shall determine that the preservation thereof is no longer desirable in the conduct of the business of the Company and its Restricted Subsidiaries, taken as a whole; and provided, further, that the Company and its Restricted Subsidiaries that are organized in a jurisdiction in Canada (including a jurisdiction in any province, territory or political subdivision thereof) shall be permitted to change the jurisdiction of its existence to another jurisdiction in Canada or the United States (including a jurisdiction in any state, province, territory or political subdivision thereof).

-95- SC1:3839600.5 Section 4.14 Change of Control. (a) Upon the occurrence of a Change of Control, the Company will make an Offer to Purchase all of the outstanding Notes at a Purchase Price in cash equal to 101% of the principal amount tendered, together with accrued interest, if any, to, but not including, the Purchase Date; provided that if the Company has exercised its right to redeem all of the Notes pursuant to Section 3.07 prior to the time the Company would be required to make an Offer to Purchase, the Company shall not be required to make such Offer to Purchase. (b) For purposes of this Section 4.14, an Offer to Purchase shall be deemed to have been made if (i) within 60 days following the date of the consummation of a transaction or series of transactions that constitutes a Change of Control, the Company commences an Offer to Purchase for all outstanding Notes at the Purchase Price and (ii) all Notes properly tendered pursuant to the Offer to Purchase are purchased on the terms of such Offer to Purchase. (c) The Company will comply with the requirements of Rule 14e-1 under the Exchange Act and any other applicable securities laws or regulations, including Canadian Securities Laws, in connection with any repurchase of the Notes pursuant to this Section 4.14. To the extent that the provisions of any applicable securities laws or regulations conflict with the provisions of this Indenture, the Company will comply with the applicable securities laws and regulations and will be deemed to have complied with its obligations under this Indenture by virtue of such compliance with the applicable securities laws and regulations. (d) The Company will not be required to make an Offer to Purchase upon a Change of Control if (i) a third party makes such Offer to Purchase contemporaneously with or upon a Change of Control in the manner, at the times and otherwise in compliance with the requirements set forth in this Section 4.14 and such third party purchases all Notes validly tendered and not withdrawn under such Offer to Purchase or (ii) a notice of redemption has been given pursuant to Section 3.07. (e) If Holders of not less than 90% in aggregate principal amount of the outstanding Notes validly tender and do not withdraw such Notes in an Offer to Purchase and the Company, or any other Person making an Offer to Purchase in lieu of the Company pursuant to this Section 4.14, purchases all of the Notes validly tendered and not withdrawn by such Holders, then the Company or such Person will have the right, upon not less than 15 nor more than 60 days’ prior notice; provided that such notice is given not more than 30 days following such purchase pursuant to the Offer to Purchase pursuant to this Section 4.14, to redeem all Notes that remain outstanding following such purchase at a price in cash equal to 101% of the aggregate principal amount of such Notes, plus, to the extent not already included, accrued and unpaid interest, if any, on the Notes that remain outstanding to, but not including, the redemption date (subject to the right of Holders of record on the relevant Record Date to receive interest due on an Interest Payment Date that is on or prior to the redemption date). (f) An Offer to Purchase may be made in advance of a Change of Control, conditional upon the occurrence of such Change of Control, if a definitive agreement is in place for the Change of Control at the time of launching the Offer to Purchase.

-96- SC1:3839600.5 (g) Other than as specifically provided in this Section 4.14, any purchase pursuant to this Section 4.14 shall be made pursuant to the provisions of Sections 3.02, 3.05 and 3.06. Section 4.15 Additional Note Guarantees. (a) After the Issue Date, the Company will cause each of its Restricted Subsidiaries (other than any Restricted Subsidiary that is a “controlled foreign corporation” as defined under Section 957 of the Code) that (1) is a borrower under any Credit Facility or (2) Guarantees any Debt of the Company or any of its Restricted Subsidiaries Incurred under any Credit Facility to Guarantee the Notes pursuant to a supplemental indenture substantially in the form of Exhibit D attached to this Indenture (or such other documents or instruments in form reasonably satisfactory to the Trustee); provided that, for the duration of any period during which no such Credit Facilities exist, the Company will cause a sufficient number of its Restricted Subsidiaries to Guarantee the Notes such that (i) each Non-Guarantor Subsidiary comprises no more than 5% of (x) Consolidated Total Assets or (y) Consolidated Adjusted EBITDA and (ii) all Non-Guarantor Subsidiaries comprise, in the aggregate, no more than 10% of (x) Consolidated Total Assets or (y) Consolidated Adjusted EBITDA. (b) Each Note Guarantee will state that it will be limited to an amount not to exceed the maximum amount that can be Guaranteed by that Restricted Subsidiary without rendering the Guarantee, as it relates to such Restricted Subsidiary, voidable under applicable law relating to fraudulent conveyance or fraudulent transfer or similar laws affecting the rights of creditors generally. (c) Each Note Guarantee shall be released in accordance with the provisions of Section 10.06. Section 4.16 Sale and Leaseback Transactions. (a) The Company will not, and will not permit any of its Restricted Subsidiaries to, enter into any Sale and Leaseback Transaction involving an aggregate amount in excess of $10 million unless: (1) the consideration received in such Sale and Leaseback Transaction is at least equal to the Fair Market Value of the property sold; (2) prior to and after giving effect to the Attributable Debt in respect of such Sale and Leaseback Transaction, the Company and such Restricted Subsidiary comply with Section 4.09; and (3) at or after the time of giving effect to the Attributable Debt in respect of such Sale and Leaseback Transaction, the Company and such Restricted Subsidiary comply with Section 4.10.

-97- SC1:3839600.5 Section 4.17 Business Activities. (a) The Company will not, and will not permit any Restricted Subsidiary to, engage in any business other than a Permitted Business. Section 4.18 Creation of Unrestricted Subsidiaries. (a) After the Issue Date, the Company may designate any Subsidiary of the Company to be an “Unrestricted Subsidiary” as provided in this Section 4.18, in which event such Subsidiary and each other Person that is then or thereafter becomes a Subsidiary of such Subsidiary will be deemed to be an Unrestricted Subsidiary. (b) The Board of Directors of the Company may designate any Subsidiary of the Company (including any newly acquired or newly formed Subsidiary or a Person becoming a Subsidiary through merger, amalgamation, consolidation, arrangement or Investment therein) to be an Unrestricted Subsidiary after the Issue Date only if: (1) neither the Company nor any of its Restricted Subsidiaries: (A) provides credit support for, or Guarantee of, any Debt of such Subsidiary or any Subsidiary of such Subsidiary (including any undertaking, agreement or instrument evidencing such Debt); (B) is directly or indirectly liable for any Debt of such Subsidiary or any Subsidiary of such Subsidiary; or (C) has any obligation to maintain or preserve such Subsidiary’s financial condition or to cause such Subsidiary to achieve any specified levels of operating results, including by way of subscription for additional Capital Interests of such Subsidiary; and such Subsidiary does not own any Capital Interests of, or own or hold any Lien on any property of, any Restricted Subsidiary of the Company; and (2) either: (A) the Subsidiary to be so designated has total assets of $2 million or less; or (B) the Company could make a Restricted Payment at the time of designation in an amount equal to the greater of the Fair Market Value or net book value of such Subsidiary pursuant to Section 4.07 (and such amount is thereafter treated as a Restricted Payment for the purpose of calculating the amount available for Restricted Payments thereunder).

-98- SC1:3839600.5 (c) Any such designation by the Company shall be evidenced to the Trustee by filing with the Trustee an Officer’s Certificate certifying that such designation complies with the foregoing conditions. (d) The Company may designate any Unrestricted Subsidiary to be a Restricted Subsidiary of the Company; provided that, immediately after giving effect to such designation, (i) the Company could Incur at least $1.00 of additional Debt pursuant to Section 4.09(a) on a Pro Forma Basis taking into account such designation, and (ii) the Company could Incur the Liens on the property and assets of such Unrestricted Subsidiary pursuant to Section 4.12. (e) Nothing in this Indenture shall prevent the Company or a Restricted Subsidiary from pledging the Capital Interests of any Unrestricted Subsidiary so long as such transaction otherwise complies with the provisions of this Indenture. Section 4.19 Covenant Suspension on Investment Grade Rating. (a) During any period of time (a “Suspension Period”) that: (1) the Notes have Investment Grade Ratings from both of the Rating Agencies; and (2) no Default or Event of Default has occurred and is continuing, (the occurrence of the events described in the foregoing clauses (1) and (2) being collectively referred to as a “Covenant Suspension Event”), the Company and its Restricted Subsidiaries will not be subject to the provisions of Sections 4.07, 4.08, 4.09, 4.10, 4.11, 4.16 and 5.01(a)(3) (collectively, the “Suspended Covenants”). (b) In the event that the Company and its Restricted Subsidiaries are not subject to the Suspended Covenants with respect to the Notes for any Suspension Period and, subsequently, (i) either one or both Rating Agencies withdraws its rating or downgrades the rating assigned to the Notes below the required Investment Grade Rating or (ii) the Company or any of its affiliates enters into an agreement to effect a transaction that would result in a Change of Control and either one or both Rating Agencies indicate that, if consummated, such transaction (alone or together with any related recapitalization or refinancing transactions) would cause such Rating Agency to withdraw its Investment Grade Rating or downgrade the ratings assigned to the Notes below an Investment Grade Rating, and such event in clause (i) or (ii) occurs prior to the Satisfaction of the Notes (such date of withdrawal or downgrade in clause (i) or (ii), a “Reinstatement Date”), then the Company and its Restricted Subsidiaries will, after the Reinstatement Date, again be subject to the Suspended Covenants with respect to future events for the benefit of the Notes (unless and until a Suspension Event again exists) until the Satisfaction of the Notes. (c) On the Reinstatement Date, all Debt Incurred during the Suspension Period shall be classified as having been Incurred pursuant to Section 4.09(a) or, at the

-99- SC1:3839600.5 Company’s option, one of the clauses set forth in the definition of “Permitted Debt” hereunder (to the extent such Debt would be permitted to be Incurred thereunder as of the Reinstatement Date and after giving effect to Debt Incurred prior to the Suspension Period and outstanding on the Reinstatement Date), and subject to Section 4.09. To the extent such Debt would not be so permitted to be Incurred pursuant to Section 4.09(a) or (b), such Debt shall be deemed to have been outstanding on the Issue Date, so that it is classified as permitted under clause (4) of the definition of “Permitted Debt” hereunder. (d) Calculations made after the Reinstatement Date of the amount available to be made as Restricted Payments under Section 4.07 shall be made as though Section 4.07 had been in effect since the Issue Date and throughout the Suspension Period. Accordingly, Restricted Payments made during the Suspension Period shall reduce the amount available to be made as Restricted Payments under Section 4.07(a) to the extent provided therein. (e) Notwithstanding that the Suspended Covenants may be reinstated, no Default or Event of Default will be deemed to have occurred as a result of a failure to comply with the Suspended Covenants during a Suspension Period (or on the Reinstatement Date or after a Suspension Period based solely on events that occurred during the Suspension Period). (f) During a Suspension Period, but prior to the repayment, repurchase, retirement or redemption of all of the outstanding principal amount of the Notes or defeasance or satisfaction and discharge of this Indenture (collectively, the “Satisfaction of the Notes”), the Company may not designate any of the Company’s Subsidiaries as Unrestricted Subsidiaries pursuant to this Indenture unless the Company could have designated such Subsidiaries as Unrestricted Subsidiaries in compliance with this Indenture assuming the Suspended Covenants had not been suspended. (g) The Company will provide prompt written notice to the Trustee of any Covenant Suspension Event and any Reinstatement Date. The Trustee is not required under this Indenture to monitor the ratings of the Notes or to give notice to the Holders of the occurrence of any Covenant Suspension Event or any Reinstatement Date.

(b) Notwithstanding Section 5.01(a), failure to satisfy clauses (2) and (3) of Section 5.01(a) will not prohibit:

(b) In the event of a declaration of acceleration of the Notes solely because an Event of Default described in clause (5) of Section 6.01(a) has occurred and is continuing, the declaration of acceleration of the Notes shall be automatically rescinded and annulled if:

-104- SC1:3839600.5 (1) the default triggering such Event of Default pursuant to clause (5) of Section 6.01(a) shall be remedied or cured by the Company or any of its Restricted Subsidiaries or waived by the holders of the relevant Debt within 20 Business Days after the declaration of acceleration with respect thereto; and (2) (A) the rescission and annulment of the acceleration of the Notes would not conflict with any judgment or decree of a court of competent jurisdiction obtained by the Trustee for the payment of principal, premium, if any, or interest due on the Notes and (B) all existing Events of Default, except nonpayment of principal, premium, if any, or interest on the Notes that became due solely because of the acceleration of the Notes, have been cured or waived. Section 6.02 Acceleration. (a) If an Event of Default (other an Event of Default specified in clause (7) or (8) of Section 6.01(a) with respect to the Company) occurs and is continuing, the Trustee by written notice to the Company, specifying the Event of Default, or the Holders of at least 25% in aggregate principal amount of the then outstanding Notes by written notice to the Company and the Trustee, may, and the Trustee at the written request of such Holders shall, declare the principal of, premium, if any, and accrued and unpaid interest, if any, on all the Notes to be due and payable immediately. Upon such a declaration, such principal, premium, if any, and accrued and unpaid interest, if any, shall be due and payable immediately. (b) If an Event of Default specified in clause (7) or (8) of Section 6.01(a) occurs with respect to the Company and is continuing, the principal of, premium, if any, and accrued and paid interest, if any, on all the Notes shall become and be immediately due and payable without any declaration or other act on the part of the Trustee or any Holders. Section 6.03 Other Remedies. If an Event of Default occurs and is continuing, the Trustee may pursue any available remedy to collect the payment of principal, premium, if any, and interest, if any, on the Notes or to enforce the performance of any provision of the Notes or this Indenture. The Trustee may maintain a proceeding even if it does not possess any of the Notes or does not produce any of them in the proceeding. A delay or omission by the Trustee or any Holder of a Note in exercising any right or remedy accruing upon an Event of Default shall not impair the right or remedy or constitute a waiver of or acquiescence in the Event of Default. All remedies are cumulative to the extent permitted by law. Section 6.04 Waiver of Past Defaults. The Holders of not less than a majority in aggregate principal amount of the outstanding Notes may on behalf of the Holders of all the Notes waive any past Default or Event of Default and its consequences hereunder, except a Default or Event of Default:

-105- SC1:3839600.5 (1) in any payment in respect of the principal of (or premium, if any) or interest on any Notes (including any Note which is required to have been purchased pursuant to an Offer to Purchase which has been made by the Company), or (2) in respect of a covenant or provision hereof which under the Indenture cannot be modified or amended without the consent of the Holder of each outstanding Note affected, each of which, for the avoidance of doubt, shall require the consent of all the Holders of the Notes outstanding. Upon any such waiver, such Default shall cease to exist, and any Event of Default arising therefrom shall be deemed to have been cured for every purpose of this Indenture, but no such waiver shall extend to any subsequent or other Default or impair any right consequent thereon. Section 6.05 Control by Majority. The Holders of a majority in aggregate principal amount of the outstanding Notes may direct the time, method and place of conducting any proceeding for exercising any remedy available to the Trustee or of exercising any trust or power conferred on the Trustee. However, the Trustee may refuse to follow any direction that conflicts with applicable law or this Indenture, the Notes or any Note Guarantee, or that the Trustee determines in good faith is unduly prejudicial to the rights of any other Holder or that would involve the Trustee in personal liability or expense for which the Trustee has not been offered an indemnity reasonably satisfactory to it. Section 6.06 Limitation on Suits. Subject to Section 6.07, no Holder of a Note may pursue any remedy with respect to this Indenture or the Notes unless: (1) such Holder has previously given the Trustee written notice that an Event of Default is continuing; (2) the Holders of at least 25% in aggregate principal amount of the then outstanding Notes have requested in writing that the Trustee pursue the remedy; (3) such Holders have offered and if requested, agreed to provide, the Trustee with security or indemnity reasonably satisfactory to the Trustee against any loss, liability or expense; (4) the Trustee has not complied with such written request made hereunder within 60 days after the receipt thereof and the offer of, and, if requested, the agreement to provide security or indemnity; and

-106- SC1:3839600.5 (5) the Holders of a majority in aggregate principal amount of the then outstanding Notes have not given the Trustee a direction that, in the reasonable opinion of the Trustee, is inconsistent with such request within such 60-day period. A Holder may not use this Indenture to prejudice the rights of another Holder or to obtain a preference or priority over another Holder, it being understood that the Trustee does not have an affirmative duty to ascertain whether or not any actions or forbearances by a Holder are unduly prejudicial to other Holders. Section 6.07 Rights of Holders to Receive Payment. Notwithstanding any other provision of this Indenture, the right of any Holder to receive payment of principal, premium, if any, and interest, if any, on its Note, on or after the respective due dates expressed or provided for in such Note (including in connection with an Offer to Purchase), or to bring suit for the enforcement of any such payment on or after such respective dates, shall not be impaired or affected without the consent of such Holder. Section 6.08 Collection Suit by Trustee. If an Event of Default specified in Section 6.01(a)(1) or (2) occurs and is continuing, the Trustee may recover judgment in its own name and as trustee of an express trust against the Company and any other obligor on the Notes, including the Guarantors, for the whole amount of principal of, premium, if any, and interest, if any, remaining unpaid on the Notes, together with interest, if any, on overdue principal and, to the extent lawful, interest, if any, and such further amount as shall be sufficient to cover the costs and expenses of collection, including the reasonable compensation, expenses, disbursements and advances of the Trustee and its agents and counsel. Section 6.09 Restoration of Rights and Remedies. If the Trustee or any Holder has instituted any proceeding to enforce any right or remedy under this Indenture and such proceeding has been discontinued or abandoned for any reason, or has been determined adversely to the Trustee or to such Holder, then and in every such case, subject to any determination in such proceedings, the Company, the Guarantors, the Trustee and the Holders shall be restored severally and respectively to their former positions hereunder and thereafter all rights and remedies of the Trustee and the Holders shall continue as though no such proceeding has been instituted. Section 6.10 Rights and Remedies Cumulative. Except as otherwise provided with respect to the replacement or payment of mutilated, destroyed, lost or stolen Notes in Section 2.07, no right or remedy herein conferred upon or reserved to the Trustee or to the Holders is intended to be exclusive of any other right or remedy, and every right and remedy are, to the extent permitted by law, cumulative and in addition to every other right and remedy given hereunder or now or hereafter existing at law or in equity or otherwise. The assertion or employment of any right or remedy hereunder, or

-107- SC1:3839600.5 otherwise, shall not prevent the concurrent assertion or employment of any other appropriate right or remedy. Section 6.11 Delay or Omission Not Waiver. No delay or omission of the Trustee or of any Holder to exercise any right or remedy accruing upon any Event of Default shall impair any such right or remedy or constitute a waiver of any such Event of Default or an acquiescence therein. Every right and remedy given by this Article or by law to the Trustee or to the Holders may be exercised from time to time, and as often as may be deemed expedient, by the Trustee or by the Holders, as the case may be. Section 6.12 Trustee May File Proofs of Claim. The Trustee may file proofs of claim and other papers or documents as may be necessary or advisable in order to have the claims of the Trustee (including any claim for the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel) and the Holders of the Notes allowed in any judicial proceedings relative to the Company (or any other obligor upon the Notes, including the Guarantors), its creditors or its property and is entitled and empowered to participate as a member in any official committee of creditors appointed in such matter and to collect, receive and distribute any money or other property payable or deliverable on any such claims. Any custodian in any such judicial proceeding is hereby authorized by each Holder to make such payments to the Trustee, and in the event that the Trustee shall consent to the making of such payments directly to the Holders, to pay to the Trustee any amount due to it for the reasonable compensation, expenses, disbursements and advances of the Trustee and its agents and counsel, and any other amounts due the Trustee under Section 7.07. To the extent that the payment of any such compensation, expenses, disbursements and advances of the Trustee, its agents and counsel, and any other amounts due the Trustee under Section 7.07 out of the bankruptcy estate in any such proceeding, shall be denied for any reason, payment of the same shall be secured by a Lien on, and shall be paid out of, any and all distributions, dividends, money, securities and other properties that the Holders may be entitled to receive in such proceeding whether in liquidation or under any plan of reorganization or arrangement or otherwise. Nothing herein contained shall be deemed to authorize the Trustee to authorize or consent to or accept or adopt on behalf of any Holder any plan of reorganization, arrangement, adjustment or composition affecting the Notes or the rights of any Holder, or to authorize the Trustee to vote in respect of the claim of any Holder in any such proceeding. Section 6.13 Priorities. If the Trustee collects any money or property pursuant to this Article 6, it shall pay out the money in the following order: (1) to the Trustee and its agents and attorneys for amounts due under Section 7.07, including payment of all reasonable compensation, expenses and liabilities incurred, and all advances made, by the Trustee and the costs and expenses of collection;

-108- SC1:3839600.5 (2) to Holders for amounts due and unpaid on the Notes for principal, premium, if any, and interest, if any, ratably, without preference or priority of any kind, according to the amounts due and payable on the Notes for principal, premium, if any, and interest, if any, respectively; and (3) to the Company or to such party as a court of competent jurisdiction shall direct, including a Guarantor, if applicable. The Trustee may fix a record date and payment date for any payment to Holders pursuant to this Section 6.13. Promptly after any record date is set pursuant to this Section 6.13, the Trustee shall cause notice of such record date and payment date to be given to the Company and to each Holder in the manner set forth in Section 12.01. Section 6.14 Undertaking for Costs. In any suit for the enforcement of any right or remedy under this Indenture or in any suit against the Trustee for any action taken or omitted by it as a Trustee, a court in its discretion may require the filing by any party litigant in such suit of an undertaking to pay the costs of the suit, and the court in its discretion may assess reasonable costs, including reasonable attorneys’ fees and expenses, against any party litigant in the suit, having due regard to the merits and good faith of the claims or defenses made by the party litigant. This Section 6.14 does not apply to a suit by the Trustee, a suit by a Holder pursuant to Section 6.07, or a suit by Holders of more than 10% in aggregate principal amount of the then outstanding Notes. ARTICLE 7 TRUSTEE Section 7.01 Duties of Trustee. (a) If an Event of Default has occurred and is continuing, the Trustee shall exercise the rights and powers vested in it by this Indenture and use the same degree of care and skill in its exercise as a prudent person would exercise or use under the circumstances in the conduct of such person’s own affairs. (b) Except during the continuance of an Event of Default: (1) the Trustee undertakes to perform such duties and only such duties as are specifically set forth in this Indenture, and no implied covenants or obligations shall be read into this Indenture against the Trustee; and (2) in the absence of bad faith or willful misconduct on its part, the Trustee may, conclusively rely, as to the truth of the statements and the correctness of the opinions expressed therein, upon certificates or opinions furnished to the Trustee and conforming to the requirements of this Indenture. However, in the case of any such certificates or opinions which by any provision hereof are specifically required to be

-109- SC1:3839600.5 furnished to the Trustee, the Trustee shall be under a duty to examine the same to determine whether or not they conform to the requirements of this Indenture (but need not confirm or investigate the accuracy of mathematical calculations or other facts stated therein).

(d) Subject to this Article 7, if an Event of Default occurs and is continuing, the Trustee shall be under no obligation to exercise any of its rights or powers under this Indenture at the request or direction of any of the Holders unless the Holders have offered to the Trustee indemnity or security reasonably satisfactory to it against any loss, liability or expense. (e) The Trustee shall not be liable for interest on any money received by it except as the Trustee may agree in writing with the Company. (f) Money held in trust by the Trustee need not be segregated from other funds except to the extent required by law and except for money held in trust under Article 8. (g) No provision of this Indenture shall require the Trustee to expend or risk its own funds or otherwise incur financial liability in the performance of any of its duties hereunder or in the exercise of any of its rights or powers, if it shall have reasonable grounds to believe that repayment of such funds or adequate indemnity against such risk or liability is not reasonably assured to it. (h) Every provision of this Indenture relating to the conduct or affecting the liability of or affording protection to the Trustee shall be subject to the provisions of this Section 7.01. Section 7.02 Rights of Trustee. (a) In the absence of bad faith or willful misconduct on its part, the Trustee may conclusively rely on any document believed by it to be genuine and to have been signed or presented by the proper Person. The Trustee need not investigate any fact or matter stated in the document, but, in the case of any document which is specifically required to be furnished to the

-110- SC1:3839600.5 Trustee pursuant to any provision hereof, the Trustee shall examine the document to determine whether it conforms to the requirements of this Indenture (but need not confirm or investigate the accuracy of mathematical calculations or other facts stated therein). (b) Before the Trustee acts or refrains from acting, it may require an Officer’s Certificate or an Opinion of Counsel or both conforming to Section 12.03. The Trustee shall not be liable for any action it takes or omits to take in good faith in conclusive reliance on the Officer’s Certificate or Opinion of Counsel. (c) The Trustee may act through agents and shall not be responsible for the misconduct or negligence of any agent appointed with due care. (d) The Trustee shall not be liable for any action it takes or omits to take in good faith which it believes to be authorized or within its rights or powers. (e) The Trustee may consult with counsel of its selection, and the advice or opinion of counsel with respect to legal matters relating to this Indenture and the Notes, including any Opinion of Counsel, shall be full and complete authorization and protection from liability in respect to any action taken, omitted or suffered by it hereunder in good faith and in accordance with the advice or opinion of such counsel, including any Opinion of Counsel. (f) The Trustee shall not be required to give any bond or surety in respect of the performance of its powers and duties hereunder.

(h) The permissive rights of the Trustee to do things enumerated in this Indenture shall not be construed as a duty. (i) Except for an Event of Default under Sections 6.01(a)(1) or (2) hereof, the Trustee shall not be deemed to have notice or be charged with knowledge of any Default or Event of Default unless a Responsible Officer of the Trustee has actual knowledge thereof or shall have received from the Company or the Holders of not less than 25% in aggregate principal amount of the Notes then outstanding written notice thereof at the Corporate Trust Office of the Trustee, and such notice references the Notes and this Indenture. In the absence of any such notice or actual knowledge, and except for a default under Sections 6.01(a)(1) or (2) hereof, the Trustee may conclusively assume that no Default or Event of Default exists. (j) The rights, privileges, protections, immunities and benefits given to the Trustee, including, without limitation, its right to be indemnified, are extended to, and shall be enforceable by, the Trustee in each of its capacities hereunder.

-111- SC1:3839600.5 (k) In no event shall the Trustee be responsible or liable for any failure or delay in the performance of its obligations hereunder arising out of or caused by, directly or indirectly, forces beyond its control, including, without limitation, strikes, work stoppages, accidents, acts of war or terrorism, civil or military disturbances, nuclear or natural catastrophes or acts of God, and interruptions, loss or malfunctions of utilities, communications or computer (software and hardware) services, it being understood that the Trustee shall use reasonable efforts which are consistent with accepted practices in the banking industry to resume performance as soon as practicable under the circumstances and that the Company may elect to replace the Trustee pursuant to Section 7.08(a)(4) under such circumstances. (l) In no event shall the Trustee be responsible or liable for special, indirect, punitive or consequential loss or damage of any kind whatsoever (including, but not limited to, loss of profit) irrespective of whether the Trustee has been advised of the likelihood of such loss or damage and regardless of the form of action.

Section 7.03 Individual Rights of Trustee. The Trustee in its individual or any other capacity may become the owner or pledgee of Notes and may otherwise deal with the Company or its Affiliates with the same rights it would have if it were not Trustee. Any Paying Agent or Registrar may do the same with like rights. However, in the event that a Responsible Officer of the Trustee becomes aware of any conflicting interest at the time a Default or Event of Default has occurred, the Trustee must eliminate such conflict within 90 days or resign, unless such Default or Event of Default has been cured or waived prior to such 90th day. The Trustee must also comply with Section 7.10. Section 7.04 Trustee’s Disclaimer. The Trustee shall not be responsible for and makes no representation as to the validity or adequacy of this Indenture or the Notes, it shall not be accountable for the Company’s use of the proceeds from the Notes, and it shall not be responsible for any statement of the Company in this Indenture or in any document issued in connection with the sale of the Notes or in the Notes other than the Trustee’s certificate of authentication. To the extent permitted by applicable law, no recourse may be taken, directly or indirectly, with respect to the obligations of the Company or the Guarantors under the Note, the Note Guarantees or this Indenture or any related documents, any certificate or other writing delivered in connection therewith, against (i) the Trustee in its individual capacity, (ii) any

-112- SC1:3839600.5 partner, owner, beneficiary, agent, officer, director, employee, agent, successor or assign of the Trustee, each in its individual capacity, or (iii) any holder of equity in the Trustee. Section 7.05 Notice of Defaults. If a Default occurs and is continuing and is actually known to a Responsible Officer of the Trustee, the Trustee shall send to each Holder a notice of the Default within 30 days after it occurs. Except in the case of an Event of Default specified in clauses (1) or (2) of Section 6.01(a), the Trustee may withhold from the Holders notice of any continuing Default if the Trustee determines in good faith that withholding the notice is in the interests of the Holders. Notice to Holders under this Section 7.05 shall be given in the manner and to the extent provided in Trust Indenture Act Section 313(c) (whether or not applicable by law). Section 7.06 Reports by Trustee to Holders of the Notes. (a) The Trustee shall transmit to Holders reports concerning the Trustee and its actions under this Indenture. The interval between transmission of reports to be transmitted at intervals shall be 12 months. Such report shall be due on March 1 of each year following the first issuance of Notes.

The Trustee’s compensation shall not be limited by any law on compensation of a trustee of an express trust. The Company shall reimburse the Trustee upon request for all documented and reasonable out-of-pocket expenses incurred or made by it, including costs of collection, in addition to the compensation for its services. Such expenses shall include the documented and reasonable compensation and expenses, disbursements and advances of the Trustee’s agents, counsel, accountants and experts. The Company and the Guarantors, jointly and severally, shall indemnify the Trustee, its agents, representatives, officers, directors, employees and attorneys against any and all loss, liability, damage, claim (whether asserted by the Company, a Guarantor, a Holder or any other person) or expense (including documented and reasonable compensation and expenses and disbursements of the Trustee’s counsel) incurred by it in connection with the administration of this trust and the performance of its duties or in connection with the exercise or performance of any of its rights or powers hereunder. The Trustee shall notify the Company promptly of any claim for which it may seek indemnity. Failure by the Trustee to so notify the Company shall not relieve the Company of its obligations hereunder, except to the extent that such delay increases the liability of the Company or a Guarantor. The Company shall defend the claim and the Trustee shall provide reasonable cooperation in such defense. The Trustee may have separate counsel of its

-113- SC1:3839600.5 selection and the Company shall pay the documented and reasonable fees and expenses of such counsel reasonably acceptable to the Company; provided, however, that the Company shall not be required to pay such fees and expenses if the Company assumes such defense unless there is a conflict of interest between the Company and the Trustee in connection with such defense as determined by Trustee in consultation with counsel. Notwithstanding the foregoing, the Company need not reimburse any expense or indemnify against any loss, liability, damage, claim or expense incurred by the Trustee through the Trustee’s own bad faith, willful misconduct or negligence. (b) To secure the Company’s payment obligations of the Company and the Guarantors in this Section 7.07, the Trustee shall have a Lien prior to the Notes on all money or property held or collected by the Trustee, in its capacity as Trustee, other than money or property held in trust to pay principal of and interest, if any, on particular Notes. (c) The Company’s payment obligations pursuant to this Section 7.07 shall survive the resignation or removal of the Trustee and the discharge of this Indenture. When the Trustee incurs expenses after the occurrence of an Event of Default specified in Section 6.01(a)(7) or (8) with respect to the Company, the expenses are intended to constitute expenses of administration under the Bankruptcy Law. Section 7.08 Replacement of Trustee. (a) The Trustee may resign at any time by giving 30 days’ prior notice of such resignation to the Company and be discharged from the trust hereby created by so notifying the Company. The Holders of a majority in aggregate principal amount of the outstanding Notes may remove the Trustee by so notifying the Trustee and the Company in writing. The Company shall remove the Trustee if: (1) the Trustee fails to comply with Section 7.10; (2) Trustee is adjudged a bankrupt or an insolvent or an order for relief is entered with respect to the Trustee under any Bankruptcy Law; (3) a receiver or public officer takes charge of the Trustee or its property; or (4) Trustee otherwise becomes incapable of acting. (b) If the Trustee resigns or has been removed by the Holders, Holders of a majority in principal amount of the outstanding Notes may appoint a successor Trustee. Otherwise, if the Trustee resigns or is removed, or if a vacancy exists in the office of Trustee for any reason, the Company shall promptly appoint a successor Trustee. Within one year after the successor Trustee takes office, the Holders of a majority in aggregate principal amount of the then outstanding Notes may remove the successor Trustee to replace it with another successor Trustee appointed by the Company.

-114- SC1:3839600.5 (c) A successor Trustee shall deliver a written acceptance of its appointment to the retiring Trustee and to the Company. Thereupon the resignation or removal of the retiring Trustee shall become effective, and the successor Trustee shall have all the rights, powers and duties of the Trustee under this Indenture. The successor Trustee shall send a notice of its succession to Holders, and include in the notice its name and address of its Corporate Trust Office. The retiring Trustee shall promptly transfer all property held by it as Trustee to the successor Trustee, subject to the Lien provided for in Section 7.07. (d) If a successor Trustee does not take office within 60 days after the retiring Trustee resigns or is removed, the retiring Trustee, the Company or the Holders of at least 10% in principal amount of the Notes may petition, at the expense of the Company, any court of competent jurisdiction for the appointment of a successor Trustee. (e) If the Trustee fails to comply with Section 7.10, any Holder of Notes may petition any court of competent jurisdiction for the removal of the Trustee and the appointment of a successor Trustee with respect to the Notes. (f) Notwithstanding the replacement of the Trustee pursuant to this Section, the Company’s obligations under Section 7.07 shall continue for the benefit of the retiring Trustee. Section 7.09 Successor Trustee by Merger. (a) If the Trustee consolidates with, merges or converts into, or transfers all or substantially all its corporate trust business or assets to, another corporation or banking association, the resulting, surviving or transferee corporation without any further act shall, if such resulting, surviving or transferee corporation or banking association is otherwise eligible under this Indenture, be the successor Trustee. (b) In case at the time such successor or successors by merger, conversion or consolidation to the Trustee shall succeed to the trusts created by this Indenture any of the Notes shall have been authenticated but not delivered, any such successor to the Trustee may adopt the certificate of authentication of any predecessor trustee, and deliver such Notes so authenticated; and in case at that time any of the Notes shall not have been authenticated, any successor to the Trustee may authenticate such Notes either in the name of any predecessor hereunder or in the name of the successor to the Trustee; and in all such cases such certificates shall have the full force which the Notes provide or this Indenture provides that the certificate of the Trustee shall have. Section 7.10 Eligibility; Disqualification. The Trustee hereunder shall at all times be a corporation organized and doing business under the laws of the United States of America or of any state thereof that is authorized under such laws to exercise corporate trustee power, that is subject to supervision or examination by federal or state authorities and that has a combined capital and surplus of at least $100.0 million as set forth in its most recent published annual report of condition. Neither the

-115- SC1:3839600.5 Company, a Guarantor nor any person directly or indirectly controlling, controlled by, or under common control with the Company or a Guarantor may serve as Trustee. Section 7.11 Preferential Collection of Claims Against the Company. The Trustee shall comply with Trust Indenture Act Section 311(a) (whether or not applicable by law), excluding any creditor relationship listed in Trust Indenture Act Section 311(b). A Trustee who has resigned or been removed shall be subject to Trust Indenture Act Section 311(a) (whether or not applicable by law) to the extent indicated therein. ARTICLE 8 LEGAL DEFEASANCE AND COVENANT DEFEASANCE Section 8.01 Legal Defeasance. (a) Subject to the satisfaction of the conditions set forth in Section 8.03, the Company may elect, at its option, to have its obligations discharged with respect to the outstanding Notes (“Legal Defeasance”). (b) For this purpose, Legal Defeasance means that the Company will be deemed to have paid and discharged the entire indebtedness represented by the outstanding Notes which shall thereafter be deemed to be “outstanding” only for the purposes of Section 8.04 and the other Sections of this Indenture referred to in (1), (2), (4) and (5) below, and to have satisfied all of its other obligations under such Notes and this Indenture, including that of the Guarantors (and the Trustee, on demand of and at the expense of the Company, shall execute proper instruments acknowledging the same), except for the following provisions which shall survive until otherwise terminated or discharged hereunder: (1) the rights of Holders of such Notes to receive payments in respect of the principal of and any premium and interest on such Notes when payments are due; (2) the Company’s obligations with respect to such Notes concerning issuing temporary Notes, registration of Notes, mutilated, destroyed, lost or stolen Notes and the maintenance of an office or agency for payment and money for security payments held in trust; (3) the rights, powers, trusts, duties and immunities of the Trustee; (4) the Company’s right of optional redemption pursuant to Section 3.07; and (5) this Section 8.01. (c) Following the Company’s exercise of its Legal Defeasance option, payment of the Notes may not be accelerated because of an Event of Default.

-116- SC1:3839600.5 (d) Subject to compliance with this Article 8, the Company may exercise its option under this Section 8.01 notwithstanding the prior exercise of its option under Section 8.02. Section 8.02 Covenant Defeasance. (a) Subject to the satisfaction of the conditions set forth in Section 8.03, the Company may elect, at its option, to be released from its obligations under the covenants contained in Sections 4.03, 4.07, 4.08, 4.09, 4.10, 4.11, 4.12, 4.14, 4.15, 4.16, 4.17 and 4.19 and clause (4) of Section 5.01(a), including, without limitation, its obligation to make Offers to Purchase in connection with Asset Sales and any Change of Control and any omission to comply with such obligation shall not constitute a Default or an Event of Default with respect to the Notes, and the Guarantors shall be deemed to have been discharged from their obligations with respect to all Note Guarantees, on and after the date the conditions set forth in Section 8.03 are satisfied (“Covenant Defeasance”), and the Notes shall thereafter be deemed not “outstanding” for the purposes of any direction, waiver, consent or declaration or act of Holders (and the consequences of any thereof) in connection with such covenants, but shall continue to be deemed “outstanding” for all other purposes hereunder (it being understood that such Notes shall not be deemed outstanding for accounting purposes). (b) For this purpose, Covenant Defeasance means that, with respect to this Indenture and the outstanding Notes, the Company may omit to comply with and shall have no liability in respect of any term, condition or limitation set forth in any such covenant, whether directly or indirectly, by reason of any reference elsewhere herein to any such covenant or by reason of any reference in any such covenant to any other provision herein or in any other document, and such omission to comply shall not constitute a Default or an Event of Default under Section 6.01, but, except as specified above, the remainder of this Indenture and such Notes shall be unaffected thereby. In addition, upon the Company’s exercise of the option under this Section 8.02, subject to the satisfaction of the conditions set forth in Section 8.03, Sections 6.01(a)(3), 6.01(a)(4) (only with respect to the failure of the Company to comply with clause (3) of Section 5.01(a) and with respect to covenants that are released as a result of such Covenant Defeasance), 6.01(a)(5), 6.01(a)(6), 6.01(a)(7) (solely with respect to Significant Subsidiaries or a group of Restricted Subsidiaries of the Company that, taken together would constitute a Significant Subsidiary), and 6.01(a)(8) (solely with respect to Significant Subsidiaries or a group of Restricted Subsidiaries of the Company that, taken together would constitute a Significant Subsidiary), in each case, shall not constitute Events of Default. Section 8.03 Conditions to Legal or Covenant Defeasance.

Subject to any applicable abandoned property law, any money deposited with the Trustee or any Paying Agent, or then held by the Company, in trust for the payment of the principal, premium, if any, or interest on any Note and remaining unclaimed for two years after such principal, premium, if any, or interest, if any, has become due and payable shall be paid to the Company on its request or (if then held by the Company) shall be discharged from such trust; and the Holder of such Note shall thereafter look only to the Company for payment thereof, and

ARTICLE 9 AMENDMENT, SUPPLEMENT AND WAIVER Section 9.01 Without Consent of Holders. (a) Notwithstanding Section 9.02, without the consent of any Holder, the Company, the Guarantors and the Trustee, at any time and from time to time, may enter into one or more indentures supplemental to this Indenture for any of the following purposes: (1) to evidence the succession of another Person to the Company and the assumption by any such Successor Entity of the covenants of the Company in this Indenture, the Note Guarantees and the Notes in accordance with the terms of this Indenture; (2) to add to the covenants of the Company for the benefit of the Holders, or to surrender any right or power herein conferred upon the Company; (3) to add additional Events of Default; (4) to provide for certificated Notes in addition to or in place of the uncertificated Notes; (5) to evidence and provide for the acceptance of appointment under this Indenture by a successor Trustee; (6) to provide for or confirm the issuance of Additional Notes in accordance with the terms of this Indenture;

It shall be sufficient if such consent approves the substance thereof. (e) After an amendment, supplement or waiver under this Section 9.02 becomes effective, the Company shall send to the Holders of Notes affected thereby a notice briefly describing the amendment, supplement or waiver. Any failure of the Company to send such notice, or any defect therein, shall not, however, in any way impair or affect the validity of any such amendment, supplement or waiver.

-123- SC1:3839600.5 ARTICLE 10 GUARANTEES Section 10.01 Guarantee. (a) Subject to this Article 10, each of the Guarantors hereby, jointly and severally, irrevocably and unconditionally guarantees, on a senior unsecured basis, to each Holder and to the Trustee and its successors and assigns, irrespective of the validity and enforceability of this Indenture, the Notes or the obligations of the Company hereunder or thereunder, that: (1) the principal, premium, if any, and interest, if any, on the Notes shall be promptly paid in full when due, whether at Stated Maturity, by acceleration, redemption or otherwise, and interest on the overdue principal and interest on the Notes, if any, if lawful, and all other Obligations of the Company to the Holders or the Trustee hereunder or under the Notes shall be promptly paid in full or performed, all in accordance with the terms hereof and thereof; and (2) in case of any extension of time of payment or renewal of any Notes or any of such other obligations, that same shall be promptly paid in full when due or performed in accordance with the terms of the extension or renewal, whether at Stated Maturity, by acceleration or otherwise. Failing payment by the Company when due of any amount so guaranteed or any performance so guaranteed for whatever reason, the Guarantors shall be jointly and severally obligated to pay the same immediately. The Company hereby fully and unconditionally guarantees the Guarantee of each Guarantor on an unsecured, unsubordinated basis. Each Guarantor agrees that this is a guarantee of payment and not a guarantee of collection. (b) The Guarantors hereby agree that their obligations hereunder shall be unconditional, irrespective of the validity, regularity or enforceability of the Notes or this Indenture, the absence of any action to enforce the same, any waiver or consent by any Holder with respect to any provisions hereof or thereof, the recovery of any judgment against the Company, any action to enforce the same or any other circumstance which might otherwise constitute a legal or equitable discharge or defense of a guarantor. Each Guarantor hereby waives diligence, presentment, demand of payment, filing of claims with a court in the event of insolvency or bankruptcy of the Company, any right to require a proceeding first against the Company, protest, notice and all demands whatsoever and covenants that this Note Guarantee shall not be discharged except by complete performance of the obligations contained in the Notes and this Indenture, or pursuant to Section 10.06. (c) Each of the Guarantors also agrees, jointly and severally, to pay any and all costs and expenses (including reasonable attorneys’ fees and expenses) incurred by the Trustee or any Holder in enforcing any rights under this Section 10.01. (d) If any Holder or the Trustee is required by any court or otherwise to return to the Company, the Guarantors or any custodian, trustee, liquidator or other similar official acting in relation to the Company or the Guarantors, any amount paid either to the Trustee or such Holder, this Note Guarantee, to the extent theretofore discharged, shall be reinstated in full force and effect.

-124- SC1:3839600.5 (e) Each Guarantor agrees that it shall not be entitled to any right of subrogation in relation to the Holders in respect of any obligations guaranteed hereby until payment in full of all obligations guaranteed hereby. Each Guarantor further agrees that, as between the Guarantors, on the one hand, and the Holders and the Trustee, on the other hand, (1) the maturity of the obligations guaranteed hereby may be accelerated as provided in Article 6 for the purposes of this Note Guarantee, notwithstanding any stay, injunction or other prohibition preventing such acceleration in respect of the obligations guaranteed hereby, and (2) in the event of any declaration of acceleration of such obligations as provided in Article 6, such obligations (whether or not due and payable) shall forthwith become due and payable by the Guarantors for the purpose of this Note Guarantee. The Guarantors shall have the right to seek contribution from any non-paying Guarantor so long as the exercise of such right does not impair the rights of the Holders under the Note Guarantees. (f) Each Note Guarantee shall remain in full force and effect and continue to be effective should any petition be filed by or against the Company for liquidation or reorganization, should the Company become insolvent or make an assignment for the benefit of creditors or should a receiver or trustee be appointed for all or any significant part of the Company’s assets, and shall, to the fullest extent permitted by law, continue to be effective or be reinstated, as the case may be, if at any time payment and performance of the Notes are, pursuant to applicable law, rescinded or reduced in amount, or must otherwise be restored or returned by any obligee on the Notes or the Note Guarantees, whether as a “voidable preference,” “fraudulent transfer” or otherwise, all as though such payment or performance had not been made. In the event that any payment or any part thereof, is rescinded, reduced, restored or returned, the Notes shall, to the fullest extent permitted by law, be reinstated and deemed reduced only by such amount paid and not so rescinded, reduced, restored or returned. (g) In case any provision of any Note Guarantee shall be invalid, illegal or unenforceable, the validity, legality and enforceability of the remaining provisions shall not in any way be affected or impaired thereby. (h) Each payment to be made by a Guarantor in respect of its Note Guarantee shall be made without set-off, counterclaim, reduction or diminution of any kind or nature. Section 10.02 Limitation on Guarantor Liability. Each Guarantor, and by its acceptance of Notes, each Holder, hereby confirms that it is the intention of all such parties that the Note Guarantee of such Guarantor not constitute a fraudulent conveyance or a fraudulent transfer for purposes of Bankruptcy Law, the Uniform Fraudulent Conveyance Act, the Uniform Fraudulent Transfer Act or any similar federal, Canadian, provincial or state law to the extent applicable to any Note Guarantee. To effectuate the foregoing intention, the Trustee, the Holders and the Guarantors hereby irrevocably agree that the obligations of each Guarantor shall be limited to the maximum amount as will, after giving effect to such maximum amount and all other contingent and fixed liabilities of such Guarantor that are relevant under such laws and after giving effect to any collections from, rights to receive contribution from or payments made by or on behalf of any other Guarantor in respect of the obligations of such other Guarantor under this Article 10, result in the obligations of such

-125- SC1:3839600.5 Guarantor under its Note Guarantee not constituting a fraudulent conveyance or fraudulent transfer under applicable law.

The Company and each Guarantor irrevocably and unconditionally submit to the non-exclusive jurisdiction of the state and federal courts sitting in the Borough of Manhattan in the County and City of New York over any suit, action or proceeding arising out of or relating to this Indenture, the Notes or the Note Guarantees and for actions brought under the U.S. federal or state securities laws.

-134- SC1:3839600.5 Section 12.18 Conversion of Currency. If for the purposes of obtaining judgment in any court it is necessary to convert a sum due under this Indenture to the Holder from U.S. dollars to another currency, the Company and each Subsidiary Guarantor has agreed, and each Holder by holding such Note will be deemed to have agreed, to the fullest extent that the Company, each Subsidiary Guarantor and they may effectively do so, that the rate of exchange used shall be that at which in accordance with normal banking procedures such Holder could purchase U.S. dollars with such other currency in New York City, New York on the Business Day preceding the day on which final judgment is given. The Company’s and Subsidiary Guarantors’ obligations to any Holder will, notwithstanding any judgment in a currency (the “Judgment Currency”) other than U.S. dollars, be discharged only to the extent that on the Business Day following receipt by such Holder or the Trustee, as the case may be, of any amount in such Judgment Currency, such Holder may in accordance with normal banking procedures purchase U.S. dollars with the Judgment Currency. If the amount of the U.S. dollars so purchased is less than the amount originally to be paid to such Holder or the Trustee in the Judgment Currency (as determined in the manner set forth in the preceding paragraph), as the case may be, each of the Company and the Subsidiary Guarantors, jointly and severally, agrees, as a separate obligation and notwithstanding any such judgment, to indemnify the Holder and the Trustee, as the case may be, against any such loss. If the amount of the U.S. dollars so purchased is more than the amount originally to be paid to such Holder or the Trustee, as the case may be, such Holder or the Trustee, as the case may be, will pay the Company and the Subsidiary Guarantors, such excess; provided that such Holder or the Trustee, as the case may be, shall not have any obligation to pay any such excess if the Company or the Subsidiary Guarantors shall have failed to pay any Holder or the Trustee any amounts then due and payable under such Note or this Indenture, in which case such excess shall be applied by such Holder or the Trustee to satisfy (to the extent thereof) such Obligations. Section 12.19 Accounting Provisions. Except as otherwise expressly provided herein, all terms of an accounting or financial nature shall be construed in accordance with IFRS, as in effect from time to time; provided that, in the event that any Accounting Change occurs and such change results in a change in the method of calculation of financial covenants, standards or terms, as determined in good faith by the Company, then, upon the written notice of the Company to the Trustee, such financial covenants, standards or terms shall be calculated on the same basis as calculated prior to giving effect to such Accounting Change and as if such Accounting Change had not occurred. Any such election with respect to such Accounting Change may not thereafter be changed. Notwithstanding anything to the contrary above or in the definition of Capital Lease Obligations, in the event of a change under IFRS (or the application thereof) requiring all leases to be capitalized, only those leases that would result or would have resulted in Capital Lease Obligations on the Issue Date (assuming for purposes hereof that they were in existence on the Issue Date) shall be considered Capital Lease Obligations and all calculations and deliverables under the Indenture shall be made in accordance therewith.
