Any notice given or action taken by a Holder or its agents with regard to different parts of such principal amount pursuant to this paragraph shall have the same effect as if given or taken by separate Holders of each such different part.

(f) Without limiting the generality of the foregoing, a Holder, including a Depositary that is the Holder of a Global Note, may make, give or take, by a proxy or proxies duly appointed in writing, any request, demand, authorization, direction, notice, consent, waiver or other action under this Indenture to be made, given or taken by Holders, and a Depositary that is the Holder of a Global Note may provide its proxy or proxies to the beneficial owners of interests in any such Global Note through such Depositary’s standing instructions and customary practices.

No act will be valid or effective for more than 90 days after the record date.

(h) With respect to any record date set pursuant to this Section 1.4, the party hereto that sets such record date may designate any day as the “expiration date” and from time to time may change the expiration date to any earlier or later day; provided that no such change shall be effective unless notice of the proposed new expiration date is given to the other

15

party hereto in writing, and to each Holder of Notes in the manner set forth in Section 11.2, on or prior to both the existing and the new expiration date.

ARTICLE 2

THE NOTES

Section 2.1 Form and Dating.

(a) The (i) Original Notes and the U.S. Trustee’s certificate of authentication and (ii) any Additional Notes (if issued as Transfer Restricted Notes) and the U.S. Trustee’s certificate of authentication shall be substantially in the form of Exhibit A hereto, which is hereby incorporated in and expressly made a part of this Indenture. The Notes may have notations, legends or endorsements required by law, stock exchange rule, agreements to which the Company, the Issuer or any Subsidiary Guarantor is subject, if any, or usage (provided that any such notation, legend or endorsement is in a form acceptable to the Issuer but which notation, legend or endorsement does not affect the rights, duties or obligations of either of the Trustees). Each Note shall be dated the date of its authentication. The Notes shall be issuable only in registered form without interest coupons and only in denominations of $2,000 and whole multiples of $1,000 in excess thereof. The terms of the Notes set forth in the Exhibits hereto are part of the terms of this Indenture. However, to the extent any provision of any Note conflicts with the express provisions of this Indenture, the provisions of this Indenture shall govern and be controlling. The Notes issued on the Issue Date shall be (A) offered and sold by the Issuer pursuant to the Purchase Agreement and (B) resold, initially only to (1) QIBs in reliance on Rule 144A and (2) Persons other than U.S. Persons (as defined in Regulation S) in reliance on Regulation S and in compliance with Canadian Securities Laws. Such Notes may thereafter be transferred to, among others, QIBs and purchasers in reliance on Regulation S and in compliance with Canadian Securities Laws. Additional Notes offered after the Issue Date may be offered and sold by the Issuer from time to time in accordance with the provisions of this Indenture and applicable law.

(b) Global Notes. Notes offered and sold in their initial distribution in reliance on Rule 144A shall be issued in the form of one or more global notes in registered form without interest coupons attached (“Rule 144A Global Notes”) deposited with the U.S. Trustee as custodian for the Depositary and registered in the name of Cede & Co., as nominee for the

16

Depositary, duly executed by the Issuer and authenticated by the U.S. Trustee as herein provided, for credit by the Depositary to the respective accounts of beneficial owners of the Notes represented thereby (or such other accounts as they may direct). Notes offered and sold in their initial distribution in reliance on Regulation S shall be issued in the form of one or more global notes in registered form without interest coupons attached (“Regulation S Global Notes” and, collectively with the 144A Global Notes, the “Global Notes”) deposited with the U.S. Trustee as custodian for the Depositary and registered in the name of Cede & Co., as nominee for the Depositary, duly executed by the Issuer and authenticated by the U.S. Trustee as herein provided, for credit by the Depositary to the respective accounts of beneficial owners of the Notes represented thereby (or such other accounts as they may direct). The aggregate principal amount of the Global Notes may from time to time be increased or decreased by adjustments made on the records of the Custodian and the Depositary or its nominee and on the schedules thereto as hereinafter provided.

(c) Book Entry Provisions. This Section 2.1(c) shall apply only to Global Notes deposited with or on behalf of the Depositary.

The Issuer shall execute and the U.S. Trustee shall, in accordance with this Section 2.1(c), authenticate and deliver initially one or more Global Notes that (i) shall be registered in the name of the Depositary for such Global Note or Global Notes or the nominee of such Depositary and (ii) shall be delivered by the U.S. Trustee to such Depositary or pursuant to such Depositary’s instructions or held by the U.S. Trustee as Custodian.

Members of, or participants in, the Depositary (“Agent Members”) shall have no rights under this Indenture with respect to any Global Note held on their behalf by the Depositary or by the U.S. Trustee as the Custodian or under such Global Note, and the Depositary may be treated by the Issuer, the U.S. Trustee and any agent of the Issuer or the U.S. Trustee as the absolute owner of such Global Note for all purposes whatsoever. Notwithstanding the foregoing, nothing herein shall prevent the Issuer, the U.S. Trustee or any agent of the Issuer or the U.S. Trustee from giving effect to any written certification, proxy or other authorization furnished by the Depositary or impair, as between the Depositary and its Agent Members, the operation of customary practices of such Depositary governing the exercise of the rights of a Holder of a beneficial interest in any Global Note.

(d) Definitive Registered Notes. Except as otherwise provided herein, owners of beneficial interests in Global Notes will not be entitled to receive physical delivery of Definitive Registered Notes.

Section 2.2 Execution and Authentication. One Officer shall sign the Notes for the Issuer by manual or facsimile signature. If an Officer whose signature is on a Note no longer holds that office at the time the U.S. Trustee authenticates the Note, the Note shall be valid nevertheless.

A Note shall not be valid until an authorized signatory of the U.S. Trustee manually or electronically signs the certificate of authentication on the Note. The signature shall be conclusive evidence that the Note has been authenticated under this Indenture.

17

On the Issue Date, the U.S. Trustee shall authenticate and deliver $650.0 million of 4.125% Senior Notes due 2031 and, at any time and from time to time thereafter, the U.S. Trustee shall authenticate and deliver Additional Notes in an aggregate principal amount specified in a Issuer Order. Such Issuer Order shall specify the amount of the Additional Notes to be authenticated and the date on which the issue of Additional Notes is to be authenticated. The aggregate principal amount of Notes which may be authenticated and delivered under this Indenture is unlimited.

The U.S. Trustee may appoint an authenticating agent reasonably acceptable to the Issuer to authenticate the Notes. Any such appointment shall be evidenced by an instrument signed by a Responsible Trust Officer, a copy of which shall be furnished to the Issuer. Unless limited by the terms of such appointment, an authenticating agent may authenticate Notes whenever the U.S. Trustee may do so. Each reference in this Indenture to authentication by the U.S. Trustee includes authentication by such agent. An authenticating agent has the same rights as any Registrar, Paying Agent or agent for service of notices and demands.

The U.S. Trustee shall receive a Company Order in connection with all requests to authenticate Notes under this Indenture.

Section 2.3 Registrar and Paying Agent.

(a) The Issuer shall maintain an office or agency where Notes may be presented for registration of transfer or for exchange (the “Registrar”) and an office or agency where Notes may be presented for payment (the “Paying Agent”). The Registrar shall keep a register of the Notes and of their transfer and exchange (the “Register”). The Issuer may have one or more co-registrars and one or more additional paying agents. The term “Paying Agent” includes any additional paying agent, and the term “Registrar” includes any co-registrars. The Issuer initially appoints the U.S. Trustee as Registrar and Paying Agent for the Global Notes, for which the U.S. Trustee shall be Custodian.

(b) The Issuer shall enter into an appropriate agency agreement with any Registrar, Paying Agent or co-registrar not a party to this Indenture. The agreement shall implement the provisions of this Indenture that relate to such agent. The Issuer shall notify the Trustees in writing of the name and address of any such agent. If the Issuer fails to maintain a Registrar or Paying Agent, the U.S. Trustee shall act as such and shall be entitled to appropriate compensation and indemnification therefor pursuant to Section 7.7. The Issuer or any of its domestically organized wholly owned Subsidiaries may act as Paying Agent (prior to an Event of Default), Registrar, co-registrar or transfer agent.

(c) The Issuer may remove any Registrar or Paying Agent upon written notice to such Registrar or Paying Agent and to the Trustees; 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 Issuer and such successor Registrar or Paying Agent, as the case may be, and delivered to the Trustees and the passage of any waiting or notice periods required by the procedures of the Depositary or (ii) written notification to the Trustees that the U.S. Trustee shall serve as Registrar or Paying Agent until the appointment of a

18

successor in accordance with clause (i) above. The Registrar or Paying Agent may resign at any time upon 30 days’ written notice to the Issuer and the Trustees.

Section 2.4 Paying Agent To Hold Money in Trust. No later than the Business Day prior to each due date of the principal, premium, if any, and interest on any Note, the Issuer shall deposit with the Paying Agent (or if the Issuer or a wholly owned Subsidiary is acting as Paying Agent, segregate and hold in trust for the benefit of the Persons entitled thereto) a sum sufficient to pay such principal, premium, if any, and interest when so becoming due. The Issuer shall require each Paying Agent (other than the U.S. Trustee) to agree in writing that the Paying Agent shall hold in trust for the benefit of Holders or the Trustees all money held by the Paying Agent for the payment of principal of or premium, if any, or interest on the Notes and shall notify the Trustees in writing of any default by the Issuer in making any such payment. If the Issuer or a Subsidiary acts as Paying Agent, it shall segregate the money held by it as Paying Agent and hold it as a separate trust fund. The Issuer at any time may require a Paying Agent to pay all money held by it to the U.S. Trustee and to account for any funds disbursed by the Paying Agent. Upon complying with this Section 2.4, the Paying Agent shall have no further liability for the money delivered to the U.S. Trustee.

Section 2.5 Holder Lists. The U.S. 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 Holders. If the U.S. Trustee is not the Registrar, the Issuer shall furnish to the U.S. Trustee, in writing at least five Business Days before each Interest Payment Date and at such other times as the U.S. Trustee may request in writing, a list in such form and as of such date as the U.S. Trustee may reasonably require of the names and addresses of Holders.

Section 2.6 Transfer and Exchange.

(a) Transfer and Exchange of Definitive Registered Notes. When Definitive Registered Notes are presented to the Registrar or a co-registrar with a request:

(i) to register the transfer of such Definitive Registered Notes; or

(ii) to exchange such Definitive Registered Notes for an equal principal amount of Definitive Registered Notes of other authorized denominations,

the Registrar or co-registrar shall register the transfer or make the exchange as requested if its reasonable requirements for such transaction are met; provided, however, that the Definitive Registered Notes surrendered for transfer or exchange:

(i) shall be duly endorsed or accompanied by a written instrument of transfer in form reasonably satisfactory to the Issuer and the Registrar or co-registrar, duly executed by the Holder thereof or his attorney duly authorized in writing; and

(ii) in the case of Transfer Restricted Notes that are Definitive Registered Notes, are being transferred or exchanged pursuant to an

19

effective registration statement under the Securities Act, a prospectus qualified under Canadian Securities Laws or pursuant to clause (A), (B) or (C) below, and are accompanied by the following additional information and documents, as applicable:

(A) if such Transfer Restricted Notes are being delivered to the Registrar by a Holder for registration in the name of such Holder, without transfer, a certification from such Holder to that effect (in substantially the form set forth on the reverse side of the Note);

(B) if such Transfer Restricted Notes are being transferred to the Issuer, a certification to that effect (in substantially the form set forth on the reverse side of the Note); or

(C) if such Transfer Restricted Notes are being transferred pursuant to an exemption from registration in reliance upon an exemption from the registration requirements of the Securities Act or an exemption from the prospectus requirement under Canadian Securities Laws, (1) a certification to that effect (in the form set forth on the reverse side of the Note) and (2) if the Issuer so requests, an opinion of counsel or other evidence reasonably satisfactory to it as to the compliance with the restrictions set forth in the legend set forth in Section 2.6(e)(i).

(b) Restrictions on Transfer of a Definitive Registered Note for a Beneficial Interest in a Global Note. A Definitive Registered Note may not be exchanged for a beneficial interest in a Global Note except upon satisfaction of the requirements set forth below. Upon receipt by the U.S. Trustee of a Definitive Registered Note, duly endorsed or accompanied by appropriate instruments of transfer, in form satisfactory to the U.S. Trustee, together with:

(i) certification (in the form set forth on the reverse side of the Note) that such Definitive Registered Note is being transferred (A) to the Issuer, (B) to the Registrar for registration in the name of a Holder, without transfer, (C) pursuant to an effective registration statement under the Securities Act or a prospectus qualified under Canadian Securities Laws, (D) to a QIB in accordance with Rule 144A, or (E) outside the United States in an offshore transaction within the meaning of Regulation S and in compliance with Rule 904 under the Securities Act (other than as provided by Rule 144) under the Securities Act and in compliance with Canadian Securities Laws, as applicable; and

(ii) written instructions directing the U.S. Trustee to make, or to direct the Custodian to make, an adjustment on its books and records with respect to such Global Note to reflect an increase in the aggregate principal amount of the Notes represented by the Global Note, such instructions to contain information regarding the Depositary account to be credited with such increase,

20

then the U.S. Trustee shall cancel such Definitive Registered Note and cause, or direct the Custodian to cause, in accordance with the standing instructions and procedures existing between the Depositary and the Custodian, the aggregate principal amount of Notes represented by the Global Note to be increased accordingly. If no Global Notes are then outstanding, the Issuer shall issue and the U.S. Trustee shall authenticate, upon written order of the Issuer in the form of an Officers’ Certificate, a new Global Note in the appropriate principal amount.

(c) Transfer and Exchange of Global Notes. The transfer and exchange of Global Notes or beneficial interests therein shall be effected through the Depositary, in accordance with this Indenture (including applicable restrictions on transfer set forth herein, if any) and the procedures of the Depositary therefor. A transferor of a beneficial interest in a Global Note shall deliver a written order given in accordance with the Depositary’s procedures containing information regarding the participant account of the Depositary to be credited with a beneficial interest in such Global Note or another Global Note and such account shall be credited in accordance with such order with a beneficial interest in the applicable Global Note and the account of the Person making the transfer shall be debited by an amount equal to the beneficial interest in the Global Note being transferred. Transfers by an owner of a beneficial interest in the Rule 144A Global Note to a transferee who takes delivery of such interest through the Regulation S Global Note, whether before or after the expiration of the Restricted Period, shall be made only upon receipt by the U.S. Trustee of (1) a certification in the form provided on the reverse side of the Notes from the transferor to the effect that such transfer is being made in accordance with Regulation S or (if available) Rule 144 under the Securities Act and in compliance with Canadian Securities Laws, as applicable, and (2) if the Issuer so requests, an opinion of counsel or other evidence reasonably satisfactory to it as to the compliance with the restrictions set forth in the legend set forth in Section 2.6(e)(i).

(i) If the proposed transfer is a transfer of a beneficial interest in one Global Note to a beneficial interest in another Global Note, the Registrar shall reflect on its books and records the date and an increase in the principal amount of the Global Note to which such interest is being transferred in an amount equal to the principal amount of the interest to be so transferred, and the Registrar shall reflect on its books and records the date and a corresponding decrease in the principal amount of the Global Note from which such interest is being transferred.

(ii) Notwithstanding any other provisions of this Indenture (other than the provisions set forth in Section 2.7), a Global Note may not be transferred as a whole except by the Depositary to a nominee of the Depositary or by a nominee of the Depositary to the Depositary or another nominee of the Depositary or by the Depositary or any such nominee to a successor Depositary or a nominee of such successor Depositary.

(d) Restrictions on Transfer of Regulation S Global Notes.

(i) Prior to the expiration of the Restricted Period, interests in the Regulation S Global Note may only be held through Euroclear or Clearstream. During the Restricted Period, beneficial ownership interests in the

21

Regulation S Global Note may only be sold, pledged or transferred through Euroclear or Clearstream in accordance with the Applicable Procedures and only (A) to the Issuer, (B) so long as such security is eligible for resale pursuant to Rule 144A, to a person whom the selling holder reasonably believes is a QIB that purchases for its own account or for the account of a QIB to whom notice is given that the resale, pledge or transfer is being made in reliance on Rule 144A, (C) in an offshore transaction in accordance with Regulation S, or (D) pursuant to an effective registration statement under the Securities Act or a prospectus qualified under Canadian Securities Laws, in each case in accordance with any applicable securities laws of any state of the United States and in compliance with Canadian Securities Laws. Prior to the expiration of the Restricted Period, transfers by an owner of a beneficial interest in the Regulation S Global Note to a transferee who takes delivery of such interest through the Rule 144A Global Note shall be made only in accordance with Applicable Procedures and upon receipt by the U.S. Trustee of a written certification from the transferor of the beneficial interest in the form provided on the reverse side of the Note to the effect that such transfer is being made to a QIB within the meaning of Rule 144A in a transaction meeting the requirements of Rule 144A. Such written certification shall no longer be required after the expiration of the Restricted Period.

(ii) Upon the expiration of the Restricted Period, beneficial ownership interests in the Regulation S Global Note shall be transferable in accordance with applicable law, including Canadian Securities Laws, and the other terms of this Indenture.

(e) Legend.

(i) Each Note certificate evidencing the Global Notes and the Definitive Registered Notes (and all Notes issued in exchange therefor or substitution thereof) shall bear a legend in substantially the following form (the “Restricted Notes Legend;” and the sixth paragraph of which is herein referred to as the “Canadian Restricted Notes Legend”):

23

HOLDING AND DISPOSITION OF THIS SECURITY OR ANY INTEREST HEREIN WILL NOT CONSTITUTE A NON-EXEMPT PROHIBITED TRANSACTION UNDER SECTION 406 OF ERISA OR SECTION 4975 OF THE CODE OR A SIMILAR VIOLATION UNDER ANY APPLICABLE SIMILAR LAWS.

UNLESS PERMITTED UNDER CANADIAN SECURITIES LEGISLATION, THE HOLDER OF THIS SECURITY MUST NOT TRADE THE SECURITY BEFORE THE DATE THAT IS FOUR MONTHS AND A DAY AFTER THE LATER OF (I) [INSERT THE ORIGINAL DISTRIBUTION DATE OF THE NOTES]; AND (II) THE DATE THE ISSUER BECAME A REPORTING ISSUER IN ANY PROVINCE OR TERRITORY OF CANADA.

(ii) Upon any sale or transfer of a Transfer Restricted Note that is a Definitive Registered Note, the Registrar shall permit the Holder thereof to exchange such Transfer Restricted Note for a Definitive Registered Note that does not bear the Restricted Notes Legend and the Definitive Registered Notes Legend and rescind any restriction on the transfer of such Transfer Restricted Note if the Holder certifies in writing to the Registrar that its request for such exchange was made in reliance on Rule 144 (such certification to be in the form set forth on the reverse side of the Notes) and, if the Issuer so requests, an opinion of counsel or other evidence reasonably satisfactory to it as to the compliance with the restrictions set forth in the legend set forth in Section 2.6(e)(i).

(iii) Any Additional Notes sold in a registered offering shall not be required to bear the Restricted Notes Legend.

At such time as all beneficial interests in a Global Note have either been exchanged for Definitive Registered Notes, redeemed, repurchased or canceled, such Global Note shall be returned to the Depositary for cancellation or retained and canceled by the U.S. Trustee in accordance with its customary procedures. At any time prior to such cancellation, if any beneficial interest in a Global Note is exchanged for Definitive Registered Notes, redeemed, repurchased or canceled, the principal amount of Notes represented by such Global Note shall be reduced and an adjustment shall be made on the books and records of the U.S. Trustee (if it is then the Custodian for such Global Note) with respect to such Global Note, by the U.S. Trustee or the Custodian, to reflect such reduction.

(g) Obligations with Respect to Transfers and Exchanges of Notes.

(i) To permit registrations of transfers and exchanges, the Issuer shall execute and the U.S. Trustee shall authenticate Definitive Registered Notes and Global Notes at the Registrar’s or co-registrar’s request.

(ii) No service charge shall be made for any registration of transfer or exchange, but the Issuer may require payment of a sum sufficient to cover any transfer tax, assessments, or similar governmental charge payable in connection therewith (other than any such transfer taxes, assessments or similar governmental charge payable upon exchanges pursuant to Sections 3.7, 4.9 and 9.4 of this Indenture).

(iii) The Registrar need not register the transfer of or exchange any Notes selected for redemption (except, in the case of a Note to be redeemed in part, the portion of the Note not to be redeemed) or to transfer or exchange any Notes for a period of 15 days prior to any date fixed for the redemption of such notes, for a period of 15 days immediately prior to the date fixed for selection of such Notes to be redeemed in part, for a period of 15 days prior to the record date with respect to any interest payment date applicable to such Notes; or which the Holder has tendered (and not withdrawn) for repurchase in connection with a Change of Control Offer.

(iv) Prior to the due presentation for registration of transfer of any Note, the Issuer, the U.S. Trustee, the Paying Agent, the Registrar or any co-registrar shall deem and treat the person in whose name a Note is registered as the absolute owner of such Note for the purpose of receiving payment of principal of and interest on such Note and for all other purposes whatsoever (whether or not such Note is overdue) and none of the Issuer, the U.S. Trustee, the Paying Agent, the Registrar or any co-registrar shall be affected by notice to the contrary.

(v) All Notes issued upon any transfer or exchange pursuant to the terms of this Indenture shall evidence the same debt and shall be entitled to the same benefits under this Indenture as the Notes surrendered upon such transfer or exchange.

(h) No Obligation of the Trustees.

(i) The Trustees shall have no responsibility or obligation to any beneficial owner of a Global Note, a member of, or a participant in the Depositary or other Person with respect to the accuracy of the records of the Depositary or its nominee or of any participant or member thereof, with respect to any ownership interest in the Notes or with respect to the delivery to any participant, member, beneficial owner or other Person (other than the Depositary) of any notice (including any notice of redemption) or the payment of any amount, under or with respect to such Notes. All notices and communications to be given to the Holders and all payments to be made to Holders under the Notes shall be given or made only to or upon the order of the registered Holders (which shall be

25

the Depositary or its nominee in the case of a Global Note). The rights of beneficial owners in any Global Note in global form shall be exercised only through the Depositary subject to the applicable rules and procedures of the Depositary. The Trustees may conclusively rely and shall be fully protected in relying upon information furnished by the Depositary with respect to its members, participants and any beneficial owners.

(ii) The Trustees shall have no obligation or duty to monitor, determine or inquire as to compliance with any restrictions on transfer imposed under this Indenture or under applicable law with respect to any transfer of any interest in any Note (including without limitation any transfers between or among Depositary participants, members or beneficial owners in any Global Note) other than to require delivery of such certificates and other documentation or evidence as are expressly required by, and to do so if and when expressly required by, the terms of this Indenture, and to examine the same to determine substantial compliance as to form with the express requirements hereof.

(i) Transfer.

Any purported transfer of such Note, or any interest therein to a purchaser or transferee that does not comply with the requirements specified in this Section 2.6 will be of no force and effect and shall be null and void ab initio.

Section 2.7 Definitive Registered Notes.

(a) The U.S. Trustee shall promptly exchange a Global Note deposited with the Depositary or with The Bank of New York Mellon, as Custodian pursuant to Section 2.1 of this Indenture for Definitive Registered Notes to be transferred to the beneficial owners thereof in an aggregate principal amount equal to the principal amount of such Global Note, in exchange for such Global Note, if (i) the Depositary notifies the Issuer that it is unwilling or unable to continue as a Depositary for such Global Note or if at any time the Depositary ceases to be a “clearing agency” registered under the Exchange Act and, in each case, a successor depositary is not appointed by the Issuer within 90 days of such notice or after the Issuer becomes aware of such cessation, or (ii) an Event of Default has occurred and is continuing and the Registrar has received a request from the Depositary or (iii) the Issuer, in its sole discretion and subject to the procedures of the Depositary, notifies the Trustees in writing that it elects to cause the issuance of Definitive Registered Notes under the Indenture.

(b) Any Global Note that is transferable to the beneficial owners thereof pursuant to this Section 2.7 shall be surrendered by the Depositary to the U.S. Trustee, to be so transferred, in whole or from time to time in part, without charge, and the U.S. Trustee shall authenticate and deliver, upon such transfer of each portion of such Global Note, an equal aggregate principal amount of Definitive Registered Notes of authorized denominations. Any portion of a Global Note transferred pursuant to this Section 2.7 shall be executed, authenticated and delivered only in denominations of $2,000 and integral multiples of $1,000 in excess thereof and registered in such names as the Depositary shall direct. Any certificated Note in the form of

26

a Definitive Registered Note delivered in exchange for an interest in the Global Note shall, except as otherwise provided by Section 2.6(e), bear the Restricted Notes Legend.

(c) Subject to the provisions of Section 2.7(b) above, the registered Holder of a Global Note may grant proxies and otherwise authorize any Person, including Agent Members and Persons that may hold interests through Agent Members, to take any action which a Holder is entitled to take under the Indenture or the Notes.

(d) In the event of the occurrence of any of the events specified in Section 2.7(a)(i), (ii) or (iii), the Issuer shall promptly make available to the U.S. Trustee a reasonable supply of Definitive Registered Notes in fully registered form without interest coupons.

Section 2.8 Replacement Notes. If a mutilated Note is surrendered to the Registrar or if a Holder claims that the Note has been lost, destroyed or wrongfully taken, the Issuer shall issue and the U.S. Trustee shall authenticate a replacement Note if the requirements of Section 8-405 of the Uniform Commercial Code are met, such that the Holder (i) notifies the Issuer and the U.S. Trustee of such loss, destruction or wrongful taking within a reasonable time after such Holder has notice of such loss, destruction or wrongful taking and the Registrar does not register a transfer prior to receiving such notification, (ii) requests a replacement Note from the Issuer and the U.S. Trustee prior to the Note being acquired by a protected purchaser and (iii) satisfies any other reasonable requirements of the Issuer and the U.S. Trustee. If required by the U.S. Trustee or the Issuer, such Holder shall furnish an indemnity bond sufficient in the judgment of the Issuer and the U.S. Trustee to protect the Issuer, the U.S. Trustee, the Paying Agent, the Registrar and any co-registrar from any loss that any of them may suffer if a Note is replaced. The Issuer and the U.S. Trustee may charge the Holder for their expenses in replacing a Note.

Section 2.9 Outstanding Notes. Notes outstanding at any time are all Notes authenticated by the U.S. Trustee except for those canceled by it, those delivered to it for cancellation and those described in this Section 2.9 as not outstanding. A Note does not cease to be outstanding because the Issuer or an Affiliate of the Issuer holds the Note.

If a Note is replaced pursuant to Section 2.8, it ceases to be outstanding unless the Trustees and the Issuer receive proof satisfactory to them that the replaced Note is held by a bona fide purchaser.

If the Paying Agent segregates and holds in trust, in accordance with this Indenture, on a redemption date or maturity date money sufficient to pay all principal and interest payable on that date with respect to the Notes (or portions thereon) to be redeemed or maturing, as the case may be, and the Paying Agent is not prohibited from paying such money to the Holders on that date pursuant to the terms of this Indenture, then on and after that date such Notes (or portions thereof) cease to be outstanding and interest on them ceases to accrue.

Section 2.10 Temporary Notes. In the event that Definitive Registered Notes are to be issued under the terms of this Indenture, until such Definitive Registered Notes are ready for delivery, the Issuer may prepare and the U.S. Trustee, upon receipt of an Issuer Order,

27

shall authenticate temporary Notes. Temporary Notes shall be substantially in the form of Definitive Registered Notes but may have variations that the Issuer considers appropriate for temporary Notes. Without unreasonable delay, the Issuer shall prepare and the U.S. Trustee shall authenticate Definitive Registered Notes and deliver them in exchange for temporary Notes upon surrender of such temporary Notes at the office or agency of the Issuer, without charge to the Holder.

Section 2.11 Defaulted Interest. If the Issuer defaults in payment of interest on the Notes, the Issuer will pay the defaulted interest (plus interest on such defaulted interest to the extent lawful) in any lawful manner. The Issuer may pay the defaulted interest to the Persons who are Holders on a subsequent special record date. The Issuer will fix or cause to be fixed any such special record date and payment date to the reasonable satisfaction of the Trustees and shall promptly mail or cause to be mailed to each Holder a notice that states the special record date, the payment date and the amount of defaulted interest to be paid.

Section 2.12 Cancellation. The Issuer at any time may deliver Notes to the U.S. Trustee for cancellation and the U.S. Trustee shall cancel such Notes in accordance with its customary procedures. The Registrar and the Paying Agent shall forward to the U.S. Trustee any Notes surrendered to them for registration of transfer, exchange or payment. The U.S. Trustee or, at the direction of the U.S. Trustee, the Registrar or the Paying Agent and no one else shall cancel and destroy (subject to the record retention requirements of the Exchange Act) all Notes surrendered for registration of transfer, exchange, payment or cancellation unless the Issuer directs the U.S. Trustee to deliver canceled Notes to the Issuer. The Issuer may not issue new Notes to replace Notes it has redeemed, paid or delivered to the U.S. Trustee for cancellation. The U.S. Trustee shall not authenticate Notes in place of canceled Notes other than pursuant to the terms of this Indenture.

Section 2.13 Additional Amounts.

(a) The Issuer, the Company and any Subsidiary Guarantor are required to make all payments under this Indenture or on the Notes free and clear of and without withholding or deduction for or on account of any present or future tax, duty, levy, impost, assessment or other governmental charge (including penalties, interest and other liabilities related thereto) (hereinafter “Taxes”) imposed or levied by or on behalf of the government of the country in which the Company, the Issuer or Subsidiary Guarantor and any successor thereof is organized or incorporated or any political subdivision or any authority or agency therein or thereof having power to tax, or any other jurisdiction in which the Company, the Issuer or any Subsidiary Guarantor is otherwise resident for tax purposes or the jurisdiction of any Paying Agent (each, a “Relevant Taxing Jurisdiction”), unless the Company, the Issuer or a Subsidiary Guarantor or Paying Agent is required to withhold or deduct Taxes by law or by the interpretation or administration thereof.

(b) If the Company, the Issuer or any Subsidiary Guarantor, or a Paying Agent is so required to withhold or deduct any amount for or on account of Taxes imposed by a Relevant Taxing Jurisdiction from any payment made under or with respect to the Notes, the Company, the Issuer or any Subsidiary Guarantor will be required to pay such additional amounts (“Additional Amounts”) with respect to the Notes as may be necessary so that the net

28

amount received by any Holder or beneficial owner (including Additional Amounts) after such withholding or deduction will not be less than the amount such Holder or beneficial owner would have received if such Taxes had not been withheld or deducted; provided, however, that the foregoing obligation to pay Additional Amounts does not apply to:

(i) any Taxes that would not have been so imposed but for the existence of any present or former connection between the relevant Holder or beneficial owner and the Relevant Taxing Jurisdiction (including a connection between a fiduciary, settlor, beneficiary, partner, member or shareholder of, or possessor of power over, the relevant holder or beneficial owner, if the relevant holder or beneficial owner is an estate, nominee, trust, partnership or corporation, and the Relevant Taxing Jurisdiction) including, without limiting the generality of the foregoing, such Holder or beneficial owner (or such fiduciary, settlor, beneficiary, partner, member, shareholder, or possessor) of the Notes being or having been a citizen, resident, or national thereof or being or having been present or engaged in a trade or business therein or having or having had a permanent establishment therein;

(ii) any estate, inheritance, gift, sales, transfer or personal property tax or similar Taxes;

(iii) any withholding or deduction in respect of the Notes (a) presented for payment by or on behalf of a Holder or beneficial owner who would have been able to avoid such withholding or deduction by presenting the relevant note to any other paying agent, or (b) where the payment could have been made without such deduction or withholding if the beneficiary of the payment had presented the notes for payment within 30 days after the date on which such payment on the notes became due and payable or the date on which payment thereof is duly provided for, whichever is later (except to the extent that the holder or beneficial owner would have been entitled to Additional Amounts had the notes been presented on the last day of such 30-day period);

(iv) any Taxes imposed with respect to any payment of principal (or premium, if any) or interest on the Notes by the Company, the Issuer or any Subsidiary Guarantor to any Holder or beneficial owner who is a fiduciary or partnership or any Person other than the sole beneficial owner of such payment, to the extent that a beneficiary or settlor with respect to such fiduciary, a member of such a partnership or the beneficial owner of such payment would not have been entitled to the Additional Amounts had such beneficiary, settlor, member or beneficial owner been the actual Holder or beneficial owner of such Notes;

(v) any Taxes that are payable other than by deduction or withholding from payments made under or with respect to the Notes;

(vi) any Taxes that would not have been imposed but for the failure of the Holder and/or beneficial owner (a) to comply with the Company’s, the Issuer’s, the Subsidiary Guarantor’s or the Paying Agent’s

29

request in writing at least 30 days before any withholding for such Taxes to the Holder to provide certification, documentation, information or other evidence concerning the nationality, residence, entitlement to treaty benefits, identity, direct or indirect ownership of or investment in the Notes, or connection with the Relevant Taxing Jurisdiction of the Holder and/or beneficial owner of such Notes, or (b) to make any valid or timely declaration or similar claim or satisfy any other reporting requirement or to provide any information relating to such matters, whether required or imposed by statute, treaty, regulation or administrative practice of the Relevant Taxing Jurisdiction, as a precondition to exemption from, or reduction in the rate of withholding or deduction of, Taxes imposed by the Relevant Taxing Jurisdiction;

(vii) with respect to any payment made by the Company or any Subsidiary Guarantor that is resident in Canada, or is a partnership any partner of which is resident in Canada, in each case, for purposes of Part XIII of the Income Tax Act (Canada), any Taxes that are required to be deducted or withheld from any payment under or in respect of the Notes as a consequence of the Holder or beneficial owner of Notes or the recipient of the interest payable on the Notes not dealing at arm’s length (within the meaning of the Income Tax Act (Canada)) with the Company or any Subsidiary Guarantor at the time of making any such payment;

(viii) with respect to any payment made by the Company or any Subsidiary Guarantor that is resident in Canada, or is a partnership any partner of which is resident in Canada, in each case, for purposes of Part XIII of the Income Tax Act (Canada), any Taxes that are required to be deducted or withheld from any payment under or in respect of the Notes as a consequence of the Holder or beneficial owner of the Notes being at any time a ‘‘specified non-resident shareholder’’ (within the meaning of subsection 18(5) of the Income Tax Act (Canada)) of the Company, the Issuer or any Subsidiary Guarantor or at any time not dealing at arm’s length (within the meaning of the Income Tax Act (Canada)) with a “specified shareholder” (within the meaning of subsection 18(5) of the Income Tax Act (Canada)) of the Company, the Issuer or any Subsidiary Guarantor or as a consequence of the payment being deemed to be a dividend under the Income Tax Act (Canada);

(ix) any Taxes payable under section 1471 through 1474 of the Code (or any successor or amended versions thereof), any regulations or other official guidance thereunder, or any agreement (including any intergovernmental agreement or any law implementing such governmental agreement) entered into in connection therewith (“FATCA”);

(x) any Taxes or penalties arising from the Holder’s or beneficial owner’s failure to comply with the Holder’s or beneficial owner’s obligations imposed under Part XVIII of the Income Tax Act (Canada), the Canada-United States Enhanced Tax Information Exchange Agreement Implementation Act (Canada) or the similar provisions of legislation of any other

30

jurisdiction that has entered into an agreement with the United States of America to provide for the implementation of FATCA based reporting; or

(xi) any combination of, or any Taxes arising from a combination of the factors described in, (i) to (x) above.

(c) At least 30 calendar days prior to each date on which any payment under or with respect to the Notes is due and payable (unless such obligation to pay Additional Amounts arises shortly before or after the 30th day prior to such date, in which case it shall be promptly thereafter), if the Issuer, the Company or any Subsidiary Guarantor will be obligated to pay Additional Amounts with respect to such payment, the Issuer will deliver to the U.S. Trustee and paying agent for the affected Notes an Officers’ Certificate stating the fact that such Additional Amounts will be payable and the amounts so payable and will set forth such other information necessary to enable the U.S. Trustee or paying agent, as the case may be, to pay such Additional Amounts to Holders and beneficial owners of such Notes on the payment date. Each such Officers’ Certificate shall be relied upon until receipt of a further Officers’ Certificate addressing such matters.

(d) The Issuer, the Company or the applicable Subsidiary Guarantor will also (i) make such withholding or deduction and (ii) remit the full amount deducted or withheld to the relevant authority in accordance with applicable law. The Issuer will provide the U.S. Trustee with official receipts or, if notwithstanding the efforts of the Issuer official receipts are not obtainable, other documentation reasonably satisfactory to the U.S. Trustee, evidencing the payment of any Tax so deducted or withheld for each Relevant Taxing Jurisdiction imposing such Taxes. The Issuer will attach to each official receipt or other documentation a certificate stating (x) that the amount of such Tax evidenced by the official receipt or other documentation was paid in connection with payments in respect of the principal amount of such Notes then outstanding and (y) the amount of such Tax paid per $1,000 of principal amount of such Notes.

(e) Whenever reference is made in this Indenture, in any context, to (i) the payment of principal, (ii) redemption prices or purchase prices in connection with a redemption or purchase of Notes, (iii) interest or (iv) any other amount payable on or with respect to the Notes, such reference will be deemed to include payment of Additional Amounts as described under this heading to the extent that, in such context, Additional Amounts are or would be payable in respect thereof.

(f) The Issuer will pay any present or future stamp, court, documentary or other similar taxes, charges or levies that arise in any jurisdiction from the execution, delivery or registration of, or enforcement of rights under, this Indenture or any related document.

(g) The obligations described under this Section 2.13 will survive any termination, defeasance or discharge of this Indenture and will apply mutatis mutandis to any jurisdiction in which any successor Person to the Company or any Subsidiary Guarantor is organized or any political subdivision or taxing authority or agency thereof or therein.

(h) The Issuer, the Company and the Subsidiary Guarantors shall indemnify and hold harmless the Trustees for the amount of any Taxes in respect of which the

31

Company, the Issuer or any Subsidiary Guarantor, is required to pay Additional Amounts pursuant to Section 2.13(b) that are levied or imposed and paid by the Trustees as a result of payments made under or with respect to the Notes, the Company Guarantee or any Subsidiary Guarantee, including any reimbursements under this clause 2.13(h).

Section 2.14 CUSIP Numbers. The Issuer in issuing the Notes may use “CUSIP” numbers, ISINs and “Common Code” numbers (in each case if then generally in use) and, if so, the U.S. Trustee shall use “CUSIP” numbers, ISINs and “Common Code” numbers in notices of redemption as a convenience to Holders; provided, however, 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 a redemption and that reliance may be placed only on the other identification numbers printed on the Notes, and any such redemption shall not be affected by any defect in or omission of such numbers. The Issuer will advise the U.S. Trustee in writing of any change in any “CUSIP” numbers, ISINs or “Common Code” numbers applicable to the Notes.

Section 2.15 Issuance of Additional Notes. After the Issue Date, the Issuer will be entitled to issue Additional Notes under this Indenture, which Notes shall have identical terms as the Notes issued on the Issue Date, other than with respect to the date of issuance, issue price, original interest accrual date and original interest payment date. All the Notes issued under this Indenture shall be treated as a single class for all purposes of this Indenture including waivers, amendments, redemptions and offers to purchase; provided, however, that unless such Additional Notes are issued under a separate CUSIP, either such Additional Notes shall be part of the same “issue” for U.S. Federal income tax purposes or shall be issued pursuant to a “qualified reopening” for U.S. Federal income tax purposes.

With respect to any Additional Notes, the Issuer will set forth in a resolution of the Board of Directors and an Officers’ Certificate, a copy of each which shall be delivered to the Trustees, the following information:

(a) the aggregate principal amount of such Additional Notes to be authenticated and delivered pursuant to this Indenture; and

(b) the issue price, the issue date and the CUSIP number of such Additional Notes.

Section 2.16 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 calendar year in which the period for which such interest or fee is payable (or compounded) ends, 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

32

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.

(c) Notwithstanding anything to the contrary herein, the Trustees shall not have any duty or obligation to calculate any interest, defaulted interest or premium on or with respect to the Notes.

ARTICLE 3

REDEMPTION

Section 3.1 Notices to the Trustees. If the Issuer elects to redeem Notes pursuant to Section 5 of the Notes, it shall notify the Trustees in writing of the redemption date and the principal amount of Notes to be redeemed.

The Issuer shall give each notice to the Trustees provided for in this Section 3.1 at least 10 days before the redemption date unless the Trustees consent to a shorter period. Such notice shall be accompanied by an Officers’ Certificate and an Opinion of Counsel from the Issuer to the effect that such redemption shall comply with the conditions herein. Any such notice may be canceled by written notice of the Issuer to the Trustees at any time prior to notice of such redemption being mailed to any Holder pursuant to Section 3.4 and shall thereby be void and of no effect.

Section 3.2 Selection of Notes To Be Redeemed. If fewer than all the Notes are to be redeemed, selection of the Notes for redemption will be made in compliance with the requirements of the principal national securities exchange, if any, on which the Notes are listed or, if the Notes are not listed but are in global form, then by lot or otherwise in accordance with the procedures of the Depositary or if the Notes are not listed and not in global form on a pro rata basis, by lot, although no note of $2,000 in original principal amount or less will be redeemed in part.

Notes and portions of them selected for redemption shall be in principal amounts of $2,000 or a whole multiple of $1,000 in excess thereof, to the extent practicable. The Issuer will redeem Notes in principal amounts of $2,000 or less in whole and not in part. Provisions of this Indenture that apply to Notes called for redemption also apply to portions of Notes called for redemption. If the Notes are being redeemed other than on a pro rata basis, the U.S. Trustee shall notify the Issuer promptly of the Notes or portions of Notes to be redeemed.

Section 3.3 Effect of Notice of Redemption. Once a notice of redemption has been sent under Section 3.4, Notes that are to be redeemed in accordance with such notice and the terms of this Article 3 shall become due and payable on the redemption date; subject to the satisfaction of any conditions in connection with the redemption. With respect to registered Notes issued in global form, the principal amount of such Note or Notes will be adjusted in accordance with the Applicable Procedures. Upon surrender to the Paying Agent, such Notes shall be paid under the terms stated in Section 3.6; provided that if the redemption date is after a record date for the payment of interest and on or prior to the related Interest Payment Date, the

33

accrued interest shall be payable to the Holder of the redeemed Notes registered on the relevant record date.

Section 3.4 Notice of Redemption.

(a) At least 10 days but not more than 60 days before a date for redemption of Notes, the Issuer will mail (in the case of Definitive Registered Notes) a notice of redemption by first-class mail (or otherwise deliver in accordance with the applicable procedures of the Depositary) to each Holder of Notes to be redeemed at such Holder’s registered address, except that redemption notices may be mailed (or otherwise delivered in accordance with the applicable procedures of the Depositary) more than 60 days prior to the redemption date if the notice is issued in connection with a defeasance of the Notes or a satisfaction and discharge of this Indenture. Any inadvertent defect in the notice of redemption, including an inadvertent failure to give notice, to any Holder selected for redemption shall not impair or affect the validity of the redemption of any other Note redeemed in accordance with the provisions of this Indenture.

The notice shall identify the Notes to be redeemed and shall state:

(i) the redemption date;

(ii) the redemption price and the amount of accrued interest to the redemption date;

(iii) the name and address of the Paying Agent;

(iv) that Notes called for redemption must be surrendered to the Paying Agent to collect the redemption price;

(v) if fewer than all the outstanding Notes are to be redeemed (and if other than on a pro rata basis), the identification numbers and principal amounts (which amounts may be stated as a ratio of the amount to be redeemed per $1,000 principal amount outstanding) of the particular Notes to be redeemed;

(vi) that, unless the Issuer defaults in making such redemption payment, interest on Notes (or portion thereof) called for redemption ceases to accrue on and after the redemption date;

(vii) the “CUSIP” number, ISIN or “Common Code” number, if any, printed on the Notes being redeemed;

(viii) that no representation is made as to the correctness or accuracy of the “CUSIP” number, ISIN or “Common Code” number, if any, listed in such notice or printed on the Notes; and

(ix) the conditions, if any, applicable to such redemption.

34

(b) At the Issuer’s request, upon written notice provided to the U.S. Trustee at least 10 days (unless a shorter period is satisfactory to the U.S. Trustee) prior to the date the redemption notice must be given to the Holders, the U.S. Trustee shall give the notice of redemption in the Issuer’s name and at the Issuer’s expense. In such event, the Issuer will provide the U.S. Trustee with the information required by this Section 3.4 and a copy of the proposed notice of redemption to be mailed to the Holders.

(c) Any redemption may, at the Issuer’s discretion, be subject to one or more conditions precedent, which will be set forth in the related notice of redemption, including, but not limited to, completion of a Qualified Equity Offering, other offering or financing or other transaction or event. In addition, if such redemption is subject to satisfaction of one or more conditions precedent, such notice will describe each such condition, and if applicable, will state that, in the Company’s discretion, the redemption date may be delayed until such time (provided, however, that any redemption date will not be more than 60 days after the date of the notice of redemption) as any or all such conditions will be satisfied, or such redemption may not occur and such notice may be rescinded in the event that any or all such conditions will not have been satisfied by the redemption date, or by the redemption date as so delayed. If any such condition precedent has not been satisfied, the Company will provide written notice to the Trustees prior to the close of business one Business Day prior to the redemption date. Upon receipt of such notice, the notice of redemption shall be rescinded or delayed, and the redemption of the Notes shall be rescinded or delayed as provided in such notice. Upon receipt, the U.S. Trustee shall provide such notice to each Holder of the Notes in the same manner in which the notice of redemption was given.

Section 3.5 Tax Redemption. The Notes may be redeemed, at the option of the Issuer, in whole but not in part, at any time upon giving not less than 15 nor more than 60 days’ written notice to the Holders (which notice shall be irrevocable) in accordance with Section 3.4 hereof, at a redemption price equal to 100% of the principal amount thereof, plus accrued and unpaid interest, if any, to the date fixed by the Company for redemption (the ‘‘Tax Redemption Date’’) if, as a result of (a) any change in, or amendment to, the laws or treaties (or any regulations or rulings promulgated thereunder) of a Relevant Taxing Jurisdiction affecting taxation (including a proposed change or amendment that, if enacted, will be effective prior to the enactment date) or (b) any change in the existing official position regarding the application, administration or interpretation of such laws, treaties, regulations or rulings (including a holding, judgment or order by a court of competent jurisdiction), which change, amendment, application, administration or interpretation is announced or becomes effective on or after the Issue Date, the Issuer, the Company or any Subsidiary Guarantor, as the case may be, is, or on the next interest payment date would be, required to pay any Additional Amounts with respect to any payment due or becoming due under the Notes or this Indenture and such requirement cannot be avoided by the taking of reasonable measures by the Issuer, the Company or a Subsidiary Guarantor, as determined in good faith by the relevant Board of Directors. Prior to the publication and mailing of any notice of redemption of the notes pursuant to this Section 3.5, the Issuer will deliver to the Trustees an Opinion of Counsel reasonably acceptable to the Trustees and setting forth in reasonable detail the circumstances giving rise to such right of redemption pursuant to clause (a) or (b) above. The provisions described under this Section 3.5 will survive any termination, defeasance or discharge of this Indenture and will apply mutatis mutandis to any jurisdiction in which any successor Person to the Issuer is organized or any political subdivision or taxing

35

authority or agency thereof or therein. Any Notes that are redeemed pursuant to this Section 3.5 shall be cancelled.

Section 3.6 Deposit of Redemption Price. On or prior to 10:00 a.m. New York City time on the relevant redemption date, the Issuer will deposit with the Paying Agent (or, if the Issuer or a wholly owned Subsidiary is the Paying Agent, shall segregate and hold in trust) money sufficient to pay the redemption price of and accrued interest, and Applicable Premium, if any, on all Notes or portions thereof to be redeemed on that date other than Notes or portions of Notes called for redemption that have been delivered by the Issuer to the U.S. Trustee for cancellation. On and after the redemption date, interest shall cease to accrue on Notes or portions thereof called for redemption so long as the Issuer has deposited with the Paying Agent funds sufficient to pay the principal of, plus accrued and unpaid interest, and Applicable Premium, if any, on, the Notes to be redeemed, unless the Paying Agent is prohibited from making such payment pursuant to the terms of this Indenture.

Section 3.7 Notes Redeemed in Part. Upon surrender of a Note that is redeemed in part, if such Note is in certificated form, the Issuer shall execute and the Trustees shall authenticate for the Holder (at the Issuer’s expense) a new Note equal in principal amount to the unredeemed portion of the Note surrendered.

53

Section 6.2 Acceleration. If an Event of Default (other than an Event of Default specified in Section 6.1(f) or (g)) occurs and is continuing, the U.S. Trustee (by written notice to the Issuer) or the Holders of not less than 30.0% in aggregate principal amount of the outstanding Notes (by written notice to the Issuer and the U.S. Trustee) may, and the U.S. Trustee at the written request of such holders shall, declare the principal amount of and premium, if any, and accrued but unpaid interest and any other monetary obligations on the Notes to be due and payable immediately. Upon that declaration, the principal amount, premium, if any, and interest shall become immediately due and payable. If an Event of Default specified in Section 6.1(f) or (g) occurs, the principal, premium, if any, and interest on all the Notes shall ipso facto become and be immediately due and payable without any declaration or other act on the part of the Trustees or any Holders. At any time after a declaration of acceleration has been made, but before a judgment or decree for payment of the money due has been obtained, the Holders of not less than a majority in aggregate principal amount of the Notes by notice to either of the Trustees may rescind and annul that declaration of acceleration and its consequences if the rescission and annulment would not conflict with any judgment or decree and if all existing Events of Default have been cured or waived except nonpayment of principal or interest that has become due solely because of acceleration. No such rescission shall affect any subsequent Default or impair any right consequent thereto.

Section 6.3 Other Remedies. If an Event of Default occurs and is continuing, the Trustees may pursue any available remedy to collect the payment of principal of or interest on the Notes or to enforce the performance of any provision of the Notes or this Indenture.

Either of the Trustees may maintain a proceeding even if they do not possess any of the Notes or do not produce any of them in the proceeding. A delay or omission by the Trustees or any Holder 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. No remedy is exclusive of any other remedy. All available remedies are cumulative.

Section 6.4 Waiver of Past Defaults. The Holders of a majority in principal amount of the Notes by notice to the Trustees may waive an existing Default and its consequences except (a) a Default in the payment of the principal of or interest on a Note, (b) a Default arising from the failure to redeem or purchase any Note when required pursuant to the terms of this Indenture or (c) a Default in respect of a provision that under Section 9.2 cannot be amended without the consent of each Holder affected. When a Default is waived, it is deemed cured, but no such waiver shall extend to any subsequent or other Default or impair any consequent right.

Section 6.5 Control by Majority. The Holders of a majority in aggregate principal amount of outstanding Notes may direct the time, method and place of conducting any proceeding for any remedy available to the U.S. Trustee or of exercising any trust or power conferred on the U.S. Trustee. However, each Trustee may refuse to follow any direction that conflicts with law or this Indenture or, subject to Section 7.1, that each Trustee determines is unduly prejudicial to the rights of other Holders or would involve each Trustee in personal liability; provided, however, that each Trustee may take any other action deemed proper by such Trustee that is not inconsistent with such direction. Prior to taking any action hereunder, each

54

Trustee shall be entitled to indemnification satisfactory to it in its sole discretion against all losses and expenses caused by taking or not taking such action.

Section 6.6 Limitation on Suits.

(a) Except to enforce the right to receive payment of principal, premium (if any) or interest when due, a Holder may not pursue any remedy with respect to this Indenture or the Notes unless:

(i) such Holder has previously given to the Trustees written notice stating that an Event of Default is continuing;

(ii) the Holders of at least 30.0% in principal amount of the outstanding Notes make a written request to the U.S. Trustee to pursue the remedy;

(iii) such Holder or Holders offer to each of the Trustees security or indemnity satisfactory to each of them against any loss, liability or expense;

(iv) the U.S. Trustee does not comply with the request within 90 days after receipt of the request and the offer of security or indemnity reasonably satisfactory to the U.S. Trustee; and

(v) the Holders of a majority in principal amount of the outstanding Notes do not give the U.S. Trustee a direction inconsistent with the request during such 90-day period.

(b) 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 neither of the Trustees has an affirmative duty to ascertain whether or not any actions or forbearances by a Holder are unduly prejudicial to other Holders. In the event that the Definitive Registered Notes are not issued to any beneficial owner promptly after the Registrar has received a request from the Holder of a Global Note to issue such Definitive Registered Notes to such beneficial owner of its nominee, the Issuer expressly agrees and acknowledges, with respect to the right of any Holder to pursue a remedy pursuant to this Indenture, the right of such beneficial holder of Notes to pursue such remedy with respect to the portion of the Global Note that represents such beneficial holder’s Notes as if such Definitive Registered Notes had been issued.

Section 6.7 Rights of Holders to Receive Payment. Notwithstanding any other provision of this Indenture, the right of any Holder to receive payment of principal of and interest on the Notes held by such Holder, on or after the respective due dates expressed in the Notes, 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 6.8 Collection Suit by U.S. Trustee. If an Event of Default specified in Section 6.1(a) or (b) occurs and is continuing, the U.S. Trustee may recover judgment in its own name and as trustee of an express trust against the Issuer or any other obligor on the Notes for

55

the whole amount then due and owing (together with interest on overdue principal and (to the extent lawful) on any unpaid interest at the rate provided for in the Notes) and the amounts provided for in Section 7.7.

Section 6.9 Trustees May File Proofs of Claim. The Trustees may file such proofs of claim and other papers or documents and take such other actions, including participating as members, voting or otherwise, of any committee of creditors appointed in the matter, as may be necessary or advisable in order to have the claims of the Trustees (including any claim for the reasonable compensation, expenses, disbursements and advances of each of the Trustees, their respective agents and counsel) and the Holders allowed in any judicial proceedings relative to the Company, the Issuer, any Subsidiary or any Subsidiary Guarantor, their creditors or their property and, unless prohibited by law or applicable regulations, may vote on behalf of the Holders in any election of a trustee in bankruptcy or other Person performing similar functions, and any custodian in any such judicial proceeding is hereby authorized by each Holder to make payments to the Trustees and, in the event that the Trustees shall consent to the making of such payments directly to the Holders, to first pay to the Trustees any amount due it for the reasonable compensation, expenses, disbursements and advances of the Trustees, their agents and counsel, and any other amounts due the Trustees under Section 7.7.

Section 6.10 Priorities. If either Trustee collects any money or property pursuant to this Article 6, it shall pay out the money or property in the following order:

FIRST: to each of the Trustees for amounts due under Section 7.7;

SECOND: Holders for amounts due and unpaid on the Notes for principal and interest, ratably, and Applicable Premium (if any), ratably, without preference or priority of any kind, according to the amounts due and payable on the Notes for principal and interest and Applicable Premium (if any), respectively; and

THIRD: to the Issuer or to such party as a court of competent jurisdiction shall direct, including the Company or a Subsidiary Guarantor, if applicable.

The U.S. Trustee may fix a record date and payment date for any payment to Holders pursuant to this Section 6.10. At least 15 days before such record date, the U.S. Trustee shall mail to each Holder and the Issuer a notice that states the record date, the payment date and amount to be paid.

Section 6.11 Undertaking for Costs. In any suit for the enforcement of any right or remedy under this Indenture or in any suit against either Trustee for any action taken or omitted by it as Trustee, a court in its discretion may require the filing by any party litigant in the 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 6.11 does not apply to a suit by the Issuer, a suit by either Trustee, a suit by a Holder pursuant to Section 6.7 or a suit by Holders of more than 10.0% in aggregate principal amount of the then outstanding Notes.

56

Section 6.12 Waiver of Stay or Extension Laws. The Company, the Issuer and each Subsidiary Guarantor agrees (to the extent it may lawfully do so) that it shall not at any time insist upon, or plead, or in any manner whatsoever claim or take the benefit or advantage of, any stay or extension law wherever enacted, now or at any time hereafter in force, which may affect the covenants or the performance of this Indenture; and the Company, the Issuer and each Subsidiary Guarantor (to the extent that it may lawfully do so) hereby expressly waives all benefit or advantage of any such law, and shall not hinder, delay or impede the execution of any power herein granted to the Trustees, but shall suffer and permit the execution of every such power as though no such law had been enacted.

ARTICLE 7

(g) No provision of this Indenture shall require the U.S. 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.

(q) No provision of this Indenture shall be deemed to impose any duty or obligation on the U.S. Trustee to take or omit to take any action, or suffer any action to be taken or omitted, in the performance of their duties or obligations under this Indenture, or to exercise any right or power thereunder, to the extent that taking or omitting to take such action or suffering such action to be taken or omitted would violate applicable law binding upon them.

(r) The U.S. Trustee may request that the Issuer deliver an Officers’ Certificate setting forth the names of individuals and/or titles of officers authorized at such time to take specific actions pursuant to this Indenture, which Officers’ Certificate may be signed by any Person authorized to sign an Officers’ Certificate, including any Person specified as son authorized in any such Officers’ Certificate previously delivered and not superseded.

(a) The Company, the Issuer and the Subsidiary Guarantors, jointly and severally, shall pay to each of the Trustees from time to time such compensation for its services as shall be agreed to in writing from time to time by the Company, the Issuer, the Subsidiary Guarantors and the Trustees. Neither of the Trustee’s compensation shall be limited by any law on compensation of a trustee of an express trust. The Issuer shall reimburse each of the Trustees upon request for all 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 reasonable compensation and expenses, disbursements and advances of each of the Trustees’ agents, counsel, accountants and experts. The Company, the Issuer and the Subsidiary

61

Guarantors, jointly and severally, shall indemnify each of the Trustees, their agents, representatives, officers, directors, employees and attorneys against any and all loss, liability, damage, claim (whether asserted by the Company, the Issuer, a Subsidiary Guarantor, a Holder or any other person) or expense (including reasonable compensation and expenses and disbursements of each of the Trustees’ counsel) arising out of or in connection with the administration of this trust and the performance of its duties, or in connection with the enforcement of any rights hereunder, or arising out of or in connection with the exercise or performance of any of its rights or powers hereunder. Each Trustee shall notify the Issuer promptly of any claim for which it may seek indemnity. Failure by a Trustee to so notify the Issuer shall not relieve the Issuer of its obligations hereunder. The Issuer shall defend the claim and each of the Trustees shall provide reasonable cooperation in such defense. Each of the Trustees may have separate counsel of its selection and the Issuer shall pay the reasonable fees and expenses of such counsel reasonably acceptable to the Issuer; provided, however, that the Issuer shall not be required to pay such fees and expenses if the Issuer assumes such defense unless there is a conflict of interest between the Issuer and either of the Trustees in connection with such defense as determined by such Trustee in consultation with counsel or if there are additional or separate defenses available to such Trustee that are not available to the Issuer and the Issuer is unable to assert any such defense on such Trustee’s behalf. Notwithstanding the foregoing, the Issuer need not reimburse any expense or indemnify against any loss, liability, damage, claim or expense incurred by either Trustee through its own willful misconduct, bad faith or negligence.

(b) To secure the payment obligations of the Company, the Issuer and the Subsidiary Guarantors in this Section 7.7, the Trustees shall have a Lien prior to the Notes on all money or property held or collected by the Trustees, in its capacity as Trustees, other than money or property held in trust to pay principal of and interest, if any, on particular Notes.

(c) The Issuer’s payment obligations pursuant to this Section 7.7 shall survive the resignation or removal of either of the Trustees and the discharge of this Indenture. When either of the Trustees incurs expenses after the occurrence of a Default specified in Section 6.1(f) or (g) with respect to the Issuer, the expenses are intended to constitute expenses of administration under the Bankruptcy Law.

Section 7.8 Replacement of Trustees.

(a) The Trustees may resign at any time by giving 30 days’ prior notice of such resignation to the Issuer and be discharged from the trust hereby created by so notifying the Issuer. The Holders of a majority in aggregate principal amount of the outstanding Notes may remove a Trustee by so notifying such Trustee and the Issuer 30 days prior in writing. The Issuer shall remove a Trustee if:

(i) such Trustee is no longer eligible under Section 7.10;

(ii) such Trustee is adjudged a bankrupt or an insolvent or an order for relief is entered with respect to such Trustee under any Bankruptcy Law;

62

(iii) a receiver or public officer takes charge of such Trustee or its property; or

(iv) such Trustee otherwise becomes incapable of acting.

(b) If a 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 a Trustee resigns or is removed (and such Holders do not reasonably promptly appoint a successor Trustee), or if a vacancy exists in the office of Trustee for any reason, the Issuer 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 Issuer. The U.S. Trustee can only be replaced by another U.S. Trustee and the Canadian Trustee can only be replaced by another Canadian Trustee, unless the responsibilities and obligations of the U.S. Trustee and the Canadian Trustee have been combined into a single trustee or the Canadian Trustee has been removed, in each case, pursuant to Section 9.1(a)(xiii).

(c) A successor Trustee shall deliver a written acceptance of its appointment to the retiring Trustee and to the Issuer. 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 7.7.

(d) If a successor Trustee does not take office within 60 days after the retiring Trustee resigns or is removed, the retiring Trustee, the Issuer or the Holders of at least 10% in principal amount of the Notes may petition, at the expense of the Issuer, 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 7.8, the Issuer’s obligations under Section 7.7 shall continue for the benefit of the retiring Trustee.

Section 7.9 Successor Trustee by Merger.

(a) If either the Canadian Trustee or U.S. Trustee consolidates with, merges or converts into, or transfers all or substantially all its corporate trust business or assets to, another Person, the resulting, surviving or transferee Person without any further act shall, if such resulting, surviving or transferee Person is otherwise eligible under this Indenture, be the successor Canadian Trustee or U.S. Trustee, as applicable.

(b) In case at the time such successor or successors by merger, conversion or consolidation to either the Canadian Trustee or U.S. Trustee shall succeed to the

63

trusts created by this Indenture, any of the Notes shall have been authenticated but not delivered, any such successor to the U.S. Trustee may adopt the certificate of authentication of any applicable 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 U.S. Trustee may authenticate such Notes either in the name of any predecessor hereunder or in the name of the successor to the U.S. 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 U.S. Trustee shall have.

Section 7.10 Eligibility; Disqualification.

(a) There shall at all times be one or more Trustees under this Indenture, at least one of whom shall at all times be a corporation organized and doing business under the laws of the United States or of any state or of the District of Columbia or a corporation or other person permitted to act as trustee by the SEC, which (1) is authorized under such laws to exercise corporate trust powers, and (2) is subject to supervision or examination by federal, state, or District of Columbia authorities.

(b) Such Trustee shall have at all times a combined capital and surplus of not less than $150,000,000 as set forth in its most recent published annual report of condition.

(c) The rights, powers, duties, and obligations conferred or imposed upon the Trustees or any of them shall be conferred or imposed upon and exercised or performed by such Trustee and such co- trustees jointly, except to the extent that under any law of any jurisdiction in which any particular act or acts are to be performed, such Trustee shall be incompetent or unqualified to perform such act or acts, in which event such rights, powers, duties, and obligations shall be exercised and performed by such co-trustees.

Section 7.11 No Liability for Co-Trustee.

No Trustee appointed hereunder shall be personally liable or responsible by reason of any act or omission of any other Trustee hereunder.

Section 7.12 Limitation on Trustees’ Liability.

Except as provided in this Article 7, in accepting the trusts hereby created, the entities acting as Trustees are acting solely as Trustees hereunder and not in their individual capacity and, except as provided in this Article 7, all Persons having any claim against either of the Trustees by reason of the transactions contemplated by this Indenture or any Note shall look only to the Issuer for payment or satisfaction thereof.

ARTICLE 8

DISCHARGE OF INDENTURE; DEFEASANCE

Section 8.1 Discharge of Liability On Notes; Defeasance.

64

(a) When (i) the Issuer delivers to the U.S. Trustee all outstanding Notes (other than Notes replaced pursuant to Section 2.8) for cancellation or (ii) all outstanding Notes not previously delivered to the U.S. Trustee for cancellation: have become due and payable, will become due and payable whether at their stated maturity within one year or are to be called for redemption within one year as a result of a mailing of a notice of irrevocable redemption pursuant to Article 3 hereof, and the Company, the Issuer or a Subsidiary Guarantor irrevocably deposits or causes to be deposited with the U.S. Trustee, in trust, money or U.S. Government Obligations, or a combination thereof (such amount to be certified in the case of U.S. Government Obligations by a nationally recognized firm of independent accountants, a nationally recognized investment bank or a nationally recognized appraisal or valuation firm, with customary assumptions expressing their opinion to the effect that the payments of principal and interest when due and without reinvestment on the deposited U.S. Government Obligations plus any deposited money without investment will provide cash at such times and in such amounts as will be sufficient to pay principal and interest when due on all the Notes to maturity or redemption, as the case may be) sufficient to pay and discharge the entire Indebtedness on the Notes not previously delivered to the U.S. Trustee for cancellation (other than Notes replaced pursuant to Section 2.8), for the principal of, premium, if any, and interest on the Notes to the date of the deposit or to the stated maturity or redemption, as the case may be, then this Indenture and all of the Issuer’s obligations in respect of the Notes shall, subject to Section 8.1(c), cease to be of further effect, and the Issuer shall be deemed to have satisfied and discharged the Indenture and all of its obligations in respect of the Notes. The Trustees shall acknowledge satisfaction and discharge of this Indenture on demand of the Issuer accompanied by an Officers’ Certificate and an Opinion of Counsel and at the cost and expense of the Issuer. For the avoidance of doubt, the Issuer will continue to be obligated to pay all other sums due under the Indenture to the Trustees.

(b) Subject to Sections 8.1(c) and 8.2, the Issuer at any time may terminate (i) all its obligations under the Notes and this Indenture (“legal defeasance option”) or (ii) its obligations under Article 4 (with the exception of Sections 4.1 and 4.3) and Article 5 and the operation of Sections 6.1(c), 6.1(d) (with respect to Sections 4.2, 4.5, 4.6, 4.7 and 4.9), 6.1(e), 6.1(f), 6.1(g), 6.1(h) and 6.1(i) (but, in the case of Sections 6.1(f) and 6.1(g), with respect only to Significant Subsidiaries and the Subsidiary Guarantors) (“covenant defeasance option”). The Issuer may exercise its legal defeasance option notwithstanding its prior exercise of its covenant defeasance option.

If the Issuer exercises its legal defeasance option, payment of the Notes may not be accelerated because of an Event of Default. If the Issuer exercises its covenant defeasance option, payment of the Notes may not be accelerated because of an Event of Default specified in Sections 6.1(c), 6.1(d) (with respect to Sections 4.2, 4.5, 4.6, 4.7 and 4.9), 6.1(e), 6.1(f), 6.1(g), 6.1(h) and 6.1(i) (but, in the case of Sections 6.1(f) and 6.1(g), with respect only to Significant Subsidiaries and the Subsidiary Guarantors) or because of the failure of the Issuer to comply with Article 5. If the Issuer exercises its legal defeasance option or its covenant defeasance option, each Subsidiary Guarantor shall be released from all its obligations with respect to its Subsidiary Guarantee.

65

Upon satisfaction of the conditions set forth herein and upon request of the Issuer, the Trustees shall acknowledge in writing the discharge of those obligations that the Issuer terminates.

(c) Notwithstanding clauses (a) and (b) above, the Issuer’s rights and obligations in Sections 2.3, 2.4, 2.5, 2.6, 2.8, 2.9, 2.10, 2.11, 2.12, 7.7, 7.8 and this Article 8 shall survive until the Notes have been paid in full. Thereafter, the Issuer’s rights and obligations in Sections 7.7 and 8.4 shall survive.

Section 8.2 Conditions to Defeasance.

(a) The Issuer or the Company may exercise its legal defeasance option or its covenant defeasance option only if:

(i) the Company or the Issuer irrevocably deposits in trust with the U.S. Trustee money in an amount sufficient or U.S. Government Obligations, the principal of and interest on which shall be sufficient, or a combination thereof sufficient to pay the principal of, and premium (if any), and interest, on the Notes when due at maturity or redemption, as the case may be, including interest thereon to maturity or such redemption date;

(ii) the Company or the Issuer delivers to the U.S. Trustee a certificate from a nationally recognized firm of independent public accountants, a nationally recognized investment bank or a nationally recognized appraisal or valuation firm, with customary assumptions expressing their opinion to the effect that the payments of principal and interest when due and without reinvestment on the deposited U.S. Government Obligations plus any deposited money without investment will provide cash at such times and in such amounts as will be sufficient to pay principal and interest when due on all the Notes to maturity or redemption, as the case may be;

(iii) the Company or the Issuer delivers to the Trustees an Opinion of Counsel in Canada to the effect that the beneficial owners of the notes will not recognize income, gain or loss for Canadian federal income tax purposes as a result of the defeasance or covenant defeasance and the defeasance or covenant defeasance will not otherwise alter those beneficial owners’ Canadian federal income tax treatment of principal and interest payments on the notes;

(iv) such defeasance or covenant defeasance does not result in a breach or violation of, or constitute a default under, any indenture or other agreement or instrument for borrowed money to which the Company is a party or by which the Issuer is bound (other than a default or event of default resulting from the borrowing of funds to be applied to such deposit and any simultaneous deposit relating to other indebtedness and, in each case, the granting of Liens in connection therewith);

(v) no Default or Event of Default under this Indenture has occurred and is continuing after giving effect to such defeasance or covenant

(viii) in the case of the covenant defeasance option, the Company or the Issuer shall have delivered to the Trustees an Opinion of Counsel to the effect that the beneficial owners of the Notes will not recognize income, gain or loss for United States federal income tax purposes as a result such defeasance and that such defeasance will not otherwise alter those beneficial owners’ United States federal income tax treatment of principal and interest payments on the Notes; and

(ix) the Company or the Issuer delivers to the Trustees an Officers’ Certificate and an Opinion of Counsel, each to the effect that all conditions precedent to such defeasance or covenant defeasance as contemplated by this Article 8 have been complied with.

(b) In connection with any defeasance or covenant defeasance involving a redemption that requires the payment of the Applicable Premium, the amount deposited with the U.S. Trustee as provided in Section 8.2(a)(i) in respect of such Applicable Premium shall be sufficient if equal to the Applicable Premium calculated as of the date of deposit, with any deficit as of the date of redemption (any such amount, the “Applicable Premium Deficit”) only required to be deposited with the U.S. Trustee on or prior to the date of redemption. Any Applicable Premium Deficit shall be set forth in an Officer’s Certificate delivered to the U.S. Trustee simultaneously with the deposit of such Applicable Premium Deficit that confirms that such Applicable Premium Deficit shall be applied toward such redemption.

Subject to any applicable abandoned property law, the U.S. Trustee and the Paying Agent shall pay to the Issuer upon request any money held by them for the payment of principal or interest that remains unclaimed for two years, and, thereafter, Holders entitled to the money must look to the Issuer for payment as general creditors.

Section 8.5 Reinstatement.

ARTICLE 9

69

not materially and adversely affect the rights of Holders to transfer the Notes (except as may be required to comply with securities laws); or

(xv) to supplement any provisions of this Indenture necessary to defease and discharge the Notes or this Indenture (in accordance with Article 8 herein); provided that such action does not adversely affect the interests of the Holders of any Notes in any material respect (as determined in good faith by the Issuer).

(b) After an amendment under this Section 9.1 becomes effective, the Issuer shall mail to Holders a notice briefly describing such amendment. The failure to give such notice to all Holders, or any defect therein, shall not impair or affect the validity of an amendment under this Section.

(a) The Company, the Issuer, the Subsidiary Guarantors and the Trustees may modify and amend any of this Indenture, the Notes and the Subsidiary Guarantees with the written consent of the Holders of not less than a majority in aggregate principal amount of the then outstanding Notes (including, without limitation, consents obtained in connection with a purchase of, or tender offer or exchange offer for, such Notes). However, no modification or amendment may, without the consent of the Holder of each outstanding Note affected thereby:

(i) change the stated maturity of the principal of, or any installment of interest payable on, the outstanding Notes;

(ii) reduce the principal amount of, or the rate of interest on, any outstanding Notes or the premium, if any, payable upon the redemption thereof that would be due and payable upon redemption of such Note (other than the provisions pursuant to Section 4.9) or would be provable in bankruptcy, or adversely affect any right of repayment of the Holder of the outstanding Notes;

(viii) release the Company from any of its obligations under the Company Guarantee or this Indenture or modify the Company Guarantee in any manner adverse to the Holders of the Notes; or

(ix) modify any of the provisions of this Section 9.2 or any of the provisions relating to the waiver of certain past defaults or provisions of this Indenture, except to increase the required percentage to effect such action or to provide that certain other provisions may not be modified or waived without the consent of all of the Holders of Notes.

(b) It shall not be necessary for the consent of the Holders under this Section to approve the particular form of any proposed amendment, but it shall be sufficient if such consent approves the substance thereof.

(c) After an amendment under this Section 9.2 becomes effective, the Issuer shall mail to Holders a notice briefly describing such amendment. The failure to give such notice to all Holders, or any defect therein, shall not impair or affect the validity of an amendment under this Section.

(d) Subject to Sections 9.1(a) and 9.2(a), 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 (including, without limitation, by consent obtained in connection with a purchase of, or tender offer or exchange offer for, such Notes) compliance by the Company or the Issuer with any provision of this Indenture. 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 (including, without limitation, by consent obtained in connection with a purchase of, or tender offer or exchange offer for, such Notes) past defaults by the Company or the Issuer under certain covenants of this Indenture which relate to the Notes. However, a default in the payment of the principal of, premium, if any, or interest on, any of the Notes or relating to a provision which under this Indenture cannot be modified or amended without the consent of the Holder of each outstanding Note affected may not be so waived.

Section 9.3 Revocation and Effect of Consents and Waivers.

(a) A consent to an amendment or a waiver by a Holder of a Note shall bind the Holder and every subsequent Holder of that Note or portion of the Note that evidences the same debt as the consenting Holder’s Note, even if notation of the consent or waiver is not made on the Note. However, any such Holder or subsequent Holder may revoke the consent or waiver as to such Holder’s Note or portion of the Note if the Trustees receive written notice of revocation at the Corporate Trust Office of the U.S. Trustee before the date the amendment or waiver becomes effective. After an amendment or waiver becomes effective, it shall bind every

71

Holder. An amendment or waiver becomes effective upon the (i) receipt by the Issuer or the Trustees of the requisite number of consents, (ii) satisfaction of the conditions to effectiveness as set forth in this Indenture and any indenture supplemental hereto containing such amendment or waiver and (iii) execution of such amendment or waiver (or Guarantee Agreement) by the Issuer and the Trustees.

(b) The Issuer may, but shall not be obligated to, fix a record date for the purpose of determining the Holders entitled to give their consent or take any other action described above or required or permitted to be taken pursuant to this Indenture. If a record date is fixed, then notwithstanding the immediately preceding paragraph, those Persons who were Holders at such record date (or their duly designated proxies), and only those Persons, shall be entitled to give such consent or to revoke any consent previously given or to take any such action, whether or not such Persons continue to be Holders after such record date. No such consent shall be valid or effective for more than 120 days after such record date.

Section 9.4 Notation on or Exchange of Notes. If an amendment changes the terms of a Note, the U.S. Trustee may require the Holder of the Note to deliver it to the U.S. Trustee. The U.S. Trustee may place an appropriate notation on the Note regarding the changed terms and return it to the Holder. Alternatively, if the Issuer or the U.S. Trustee so determines, the Issuer in exchange for the Note shall issue and the U.S. Trustee shall authenticate a new Note that reflects the changed terms. Failure to make the appropriate notation or to issue a new Note shall not affect the validity of such amendment.

Section 9.5 Trustees To Sign Amendments, etc. Each of the Trustees shall sign any amendment, supplement or waiver authorized pursuant to this Article 9 if the amendment does not adversely affect the rights, duties, liabilities or immunities of such Trustee. If it does, such Trustee may but need not sign it. In signing such amendment the Trustees shall be entitled to receive indemnity reasonably satisfactory to it and to receive, and (subject to Section 7.1) shall be fully protected in relying upon, an Officers’ Certificate and an Opinion of Counsel to the effect that such amendment is authorized or permitted by this Indenture and complies with the provisions hereof and is legally valid and binding against the Company, the Issuer and the Subsidiary Guarantors.

ARTICLE 10

The Company and each Subsidiary Guarantor hereby waive any right to which they may be entitled to require that the Issuer be sued prior to an action being initiated against the Company or such Subsidiary Guarantor.

(d) The Company and each Subsidiary Guarantor further agree that their Company Guarantee or Subsidiary Guarantee, as applicable, herein constitute a guarantee of payment, performance and compliance when due (and not a guarantee of collection) and waive any right to require that any resort be had by any Holder or the Trustees to any security held for payment of the Guaranteed Obligations.

(e) Except as expressly set forth in Section 8.1(b), 10.2 and 10.6, the obligations of the Company and each Subsidiary Guarantor hereunder shall not be subject to any reduction, limitation, impairment or termination for any reason, including any claim of waiver, release, surrender, alteration or compromise, and shall not be subject to any defense of setoff, counterclaim, recoupment or termination whatsoever or by reason of the invalidity, illegality or unenforceability of the Guaranteed Obligations or otherwise.

Without limiting the generality of the foregoing, the obligations of the Company and each Subsidiary Guarantor herein shall not be discharged or impaired or otherwise affected by the failure of any Holder or the Trustees to assert any claim or demand or to enforce any remedy

73

under this Indenture, the Notes or any other agreement, by any waiver or modification of any thereof, by any default, failure or delay, willful or otherwise, in the performance of the obligations, or by any other act or thing or omission or delay to do any other act or thing which may or might in any manner or to any extent vary the risk of the Company or any Subsidiary Guarantor or would otherwise operate as a discharge of the Company or any Subsidiary Guarantor as a matter of law or equity.

(f) Subject to Section 10.6, the Company and each Subsidiary Guarantor agree that their Company Guarantee or Subsidiary Guarantee, as applicable, shall remain in full force and effect until payment in full of all the Guaranteed Obligations. The Company and each Subsidiary Guarantor further agree, subject to Section 10.6, that their Company Guarantee or Subsidiary Guarantee, as applicable, herein shall continue to be effective or be reinstated, as the case may be, if at any time payment, or any part thereof, of principal of or interest on any Guaranteed Obligation is rescinded or must otherwise be restored by any Holder or the Trustees upon the bankruptcy or reorganization of the Issuer or otherwise.

(g) In furtherance of the foregoing and not in limitation of any other right which any Holder or the Trustees have at law or in equity against the Company or any Subsidiary Guarantor by virtue hereof, upon the failure of the Issuer to pay the principal of or interest on any Guaranteed Obligation when and as the same shall become due, whether at maturity, by acceleration, by redemption or otherwise, or to perform or comply with any other Guaranteed Obligation, the Company and each Subsidiary Guarantor hereby promise to and shall, upon receipt of written demand by the Trustees, forthwith pay, or cause to be paid, in cash, to the Holders or the Trustees an amount equal to the sum of (i) the unpaid principal amount of such Guaranteed Obligations, (ii) accrued and unpaid interest on such Guaranteed Obligations (but only to the extent not prohibited by law) and (iii) all other monetary obligations of the Issuer to the Holders and the Trustees.

(h) The Company and each Subsidiary Guarantor agree that they shall not be entitled to any right of subrogation in relation to the Holders in respect of any Guaranteed Obligations guaranteed hereby until payment or discharge in full of all Guaranteed Obligations other than obligations for fees and expenses. The Company and each Subsidiary Guarantor further agree that, as between it, on the one hand, and the Holders and the Trustees, on the other hand, (i) the maturity of the Guaranteed Obligations guaranteed hereby may be accelerated as provided in Article 6 for the purposes of the Company Guarantee or any Subsidiary Guarantee herein, notwithstanding any stay, injunction or other prohibition preventing such acceleration in respect of the Guaranteed Obligations guaranteed hereby, and (ii) in the event of any declaration of acceleration of such Guaranteed Obligations as provided in Article 6, such Guaranteed Obligations (whether or not due and payable) shall forthwith become due and payable by the Company or such Subsidiary Guarantor for the purposes of this Section 10.1.

(i) The Company and each Subsidiary Guarantor also agree to pay any and all costs and expenses (including reasonable attorneys’ fees and expenses) incurred by the Trustees or any Holder in enforcing any rights under this Section 10.1.

74

(j) Upon request of the Trustees, the Company and each Subsidiary Guarantor shall execute and deliver such further instruments and do such further acts as may be reasonably necessary or proper to carry out more effectively the purpose of this Indenture.

Section 10.2 Limitation on Liability. Any term or provision of this Indenture to the contrary notwithstanding, the maximum aggregate amount of the Guaranteed Obligations guaranteed hereunder by the Company or any Subsidiary Guarantor shall not exceed the maximum amount that can be hereby guaranteed without rendering this Indenture, as it relates to the Company or such Subsidiary Guarantor, voidable under applicable law relating to fraudulent conveyance or fraudulent transfer or voidable transaction or similar laws affecting the rights of creditors generally. This Indenture does not apply to any liability to the extent that it would result in this Indenture constituting unlawful financial assistance within the meaning of s. 678 or s. 679 of the Companies Act 2006 of the United Kingdom.

Section 10.3 Successors and Assigns. This Article 10 shall be binding upon the Company and each Subsidiary Guarantor and their successors and assigns and shall inure to the benefit of the successors and assigns of the Trustees and the Holders and, in the event of any transfer or assignment of rights by any Holder or the Trustees, the rights and privileges conferred upon that party in this Indenture and in the Notes shall automatically extend to and be vested in such transferee or assignee, all subject to the terms and conditions of this Indenture.

Section 10.4 No Waiver. Neither a failure nor a delay on the part of either the Trustees or the Holders in exercising any right, power or privilege under this Article 10 shall operate as a waiver thereof, nor shall a single or partial exercise thereof preclude any other or further exercise of any right, power or privilege. The rights, remedies and benefits of the Trustees and the Holders herein expressly specified are cumulative and not exclusive of any other rights, remedies or benefits which either may have under this Article 10 at law, in equity, by statute or otherwise.

Section 10.5 Modification. No modification, amendment or waiver of any provision of this Article 10, nor the consent to any departure by the Company or any Subsidiary Guarantor therefrom, shall in any event be effective unless the same shall be in writing and signed by the Trustees, and then such waiver or consent shall be effective only in the specific instance and for the purpose for which given. No notice to or demand on the Company or any Subsidiary Guarantor in any case shall entitle the Company or such Subsidiary Guarantor to any other or further notice or demand in the same, similar or other circumstances.

Section 10.6 Release of Guarantor. Each of the guarantors, other than the Company, may be released upon the occurrence of certain conditions. A Subsidiary Guarantor shall be automatically released from its obligations under this Article 10 (other than any obligation that may have arisen under Section 10.7) upon:

(a)

(i) the release of such Subsidiary Guarantor from its obligations as a guarantor under the Senior Credit Facilities (other than in connection with payment in full of such Senior Credit Facilities) or in respect of

(ii) the sale, issuance or other disposition of Capital Stock of such Subsidiary Guarantor (including by way of merger, amalgamation or consolidation) such that such Subsidiary Guarantor ceases to be a Subsidiary of the Company, or the sale of all or substantially all of the assets of such Subsidiary Guarantor to a Person that is not (either before or after giving effect to such transaction) the Company or a Subsidiary, so long as such sale, issuance or other disposition of Capital Stock is not prohibited by the terms of this Indenture;

(iii) immediately prior to or following the dissolution of such Subsidiary Guarantor; or

(iv) the Issuer exercising its legal defeasance option or its covenant defeasance option pursuant to Article 8 or if the Issuer’s obligations under this Indenture are discharged in accordance with the terms of this Indenture;

(b) the Company, the Issuer or such Subsidiary Guarantor delivering to the Trustees an Officers’ Certificate and an Opinion of Counsel, each stating that all conditions provided for in this Indenture relating to such transaction have been complied with, except in the case of a merger, consolidation or amalgamation of a Subsidiary Guarantor into or with the Company or the Issuer; and

(c) at the request of the Issuer, the Trustees shall execute and deliver an appropriate instrument evidencing such release (in the form provided by the Issuer).

Section 10.7 Execution of Guarantee Agreement for Future Subsidiary Guarantors. The Issuer shall cause each Subsidiary which is required to become a Subsidiary Guarantor pursuant to Section 4.7 to within the time period specified therein execute and deliver to the Trustees a Guarantee Agreement pursuant to which such Subsidiary shall become a Subsidiary Guarantor under this Article 10 and shall guarantee the Guaranteed Obligations. Concurrently with the execution and delivery of such Guarantee Agreement, the Issuer will deliver to the Trustees an Officers’ Certificate and an Opinion of Counsel stating that all conditions provided for in this Indenture relating to such transaction have been complied with except in the case of a merger, consolidation or amalgamation of a Subsidiary Guarantor into or with the Company or the Issuer.

Section 10.8 Non-Impairment. The failure to endorse a Company Guarantee or a Subsidiary Guarantee on any Note shall not affect or impair the validity thereof.

Section 10.9 Contribution. The Company and each Subsidiary Guarantor that makes a payment under its Company Guarantee or Subsidiary Guarantee, as applicable, shall be entitled upon payment in full of all Guaranteed Obligations under this Indenture to a contribution from the Company and each Subsidiary Guarantor in an amount equal to the Company’s or such Subsidiary Guarantor’s pro rata portion of such payment based on the respective net assets of the

76

Company and all the Subsidiary Guarantors at the time of such payment determined in accordance with GAAP.

The Company, the Issuer, any Subsidiary Guarantor or the Trustees by notice to the other may designate additional or different addresses for subsequent notices or communications.

Any notice or communication mailed to a Holder shall be mailed to the Holder at the Holder’s address as it appears on the Register and shall be sufficiently given if so mailed within the time prescribed.

Failure to mail a notice or communication to a Holder or any defect in it shall not affect its sufficiency with respect to other Holders. If a notice or communication is mailed in the manner provided above, it is duly given, whether or not the addressee receives it.

Where this Indenture provides for notice in any manner, such notice may be waived in writing by the Person entitled to receive such notice, either before or after the event, and such waiver shall be the equivalent of such notice. Waivers of notice by Holders shall be filed with the Trustees, but such filing shall not be a condition precedent to the validity of any action taken in reliance upon such waiver.

Where this Indenture provides for notice of any event (including any notice of redemption) to a Holder of a Global Note (whether by mail or otherwise), such notice shall be sufficiently given if given to the Depositary for such Note (or its designee), pursuant to the applicable procedures of such Depositary, if any, prescribed for the giving of such notice.

If the Issuer sends a notice or communication to the Holders, it shall mail a copy to each of the Trustees at the same time.

Section 11.3 Trustee Instructions. “Electronic Means” shall mean the following communications methods: e-mail, facsimile transmission, secure electronic transmission containing applicable authorization codes, passwords and/or authentication keys issued by the Trustees, or another method or system specified by the Trustees as available for use in connection with its services hereunder.

The Trustees shall have the right to accept and act upon instructions, including funds transfer instructions (“Instructions”) given pursuant to this Indenture and delivered using Electronic Means; provided, however, that the Issuer shall provide to the Trustees an incumbency certificate listing officers with the authority to provide such Instructions (“Authorized Officers”) and containing specimen signatures of such Authorized Officers, which incumbency certificate shall be amended by the Issuer whenever a person is to be added or deleted from the listing. If the Issuer elects to give the Trustees Instructions using Electronic Means and the Trustees in their

78

discretion elects to act upon such Instructions, the Trustees’ understanding of such Instructions shall be deemed controlling. The Issuer understands and agrees that the Trustees cannot determine the identity of the actual sender of such Instructions and that the Trustees shall conclusively presume that directions that purport to have been sent by an Authorized Officer listed on the incumbency certificate provided to the Trustees have been sent by such Authorized Officer. The Issuer shall be responsible for ensuring that only Authorized Officers transmit such Instructions to the Trustees and that the Issuer and all Authorized Officers are solely responsible to safeguard the use and confidentiality of applicable user and authorization codes, passwords and/or authentication keys upon receipt by the Issuer. The Trustees shall not be liable for any losses, costs or expenses arising directly or indirectly from the Trustees’ reliance upon and compliance with such Instructions notwithstanding such directions conflict or are inconsistent with a subsequent written instruction. The Issuer agrees: (i) to assume all risks arising out of the use of Electronic Means to submit Instructions to the Trustees, including without limitation the risk of the Trustees acting on unauthorized Instructions, and the risk of interception and misuse by third parties; (ii) that it is fully informed of the protections and risks associated with the various methods of transmitting Instructions to the Trustees and that there may be more secure methods of transmitting Instructions than the method(s) selected by the Issuer; (iii) that the security procedures (if any) to be followed in connection with its transmission of Instructions provide to it a commercially reasonable degree of protection in light of its particular needs and circumstances; and (iv) to notify the Trustees immediately upon learning of any compromise or unauthorized use of the security procedures.

Section 11.4 Certificate and Opinion as to Conditions Precedent. Upon any request or application by the Issuer to the Trustees to take or refrain from taking any action under this Indenture (except for authentication of the Notes by the Trustees on the Issue Date, which shall not require an Opinion of Counsel), the Issuer shall furnish to the Trustees:

(a) an Officers’ Certificate in form and substance reasonably satisfactory to the Trustees (which shall include the statements set forth in Section 11.5) to the effect that, in the opinion of the signers, all conditions precedent and covenants, if any, provided for in this Indenture relating to the proposed action have been complied with; and

(b) an Opinion of Counsel in form and substance reasonably satisfactory to the Trustees (which shall include the statements set forth in Section 11.5) to the effect that, in the opinion of such counsel, all such conditions precedent and covenants have been complied with.

Section 11.5 Statements Required in Certificate or Opinion. Each certificate or opinion with respect to compliance with a covenant or condition provided for in this Indenture shall include:

(a) a statement to the effect that the individual making such certificate or opinion has read such covenant or condition and the related definitions;

(b) a brief statement as to the nature and scope of the examination or investigation upon which the statements or opinions contained in such certificate or opinion are based;

79

(c) a statement to the effect that, in the opinion of such individual, he or she has made such examination or investigation as is necessary to enable him or her to express an informed opinion as to whether or not such covenant or condition has been complied with; and

(d) a statement as to whether or not, in the opinion of such individual, such covenant or condition has been complied with.

Section 11.6 When Notes Disregarded. In determining whether the Holders of the required principal amount of Notes have concurred in any direction, waiver or consent, Notes owned by the Company, the Issuer, any Subsidiary Guarantor or by any Person directly or indirectly controlling or controlled by or under direct or indirect common control with the Company, the Issuer or any Subsidiary Guarantor shall be disregarded and deemed not to be outstanding, except that, for the purpose of determining whether the Trustees shall be protected in relying on any such direction, waiver or consent, only Notes which the Trustees know are so owned shall be so disregarded. Also, subject to the foregoing, only Notes outstanding at the time shall be considered in any such determination.

Section 11.7 Rules by U.S. Trustee, Paying Agent and Registrar. The U.S. Trustee may make reasonable rules for action by or a meeting of Holders. The Canadian Trustee, Registrar or the Paying Agent may make reasonable rules for their functions.

Section 11.8 Business Days. If a payment date is not a Business Day, payment shall be made on the next succeeding day that is a Business Day, and no interest shall accrue for the intervening period. If a regular record date is not a Business Day, the record date shall not be affected.

Section 11.9 Governing Law. This Indenture and the Notes shall be governed by, and construed in accordance with, the laws of the State of New York. This Indenture provides that the Company, the Issuer, the Trustees, and each Holder by its acceptance hereof, irrevocably waives, to the fullest extent permitted by applicable law, any and all right to trial by jury in any legal proceeding arising out of or relating to this Indenture, the Notes or any transaction contemplated hereby or thereby.

Section 11.10 No Recourse Against Others. A director, officer, employee or stockholder, as such, of the Company, the Issuer or any Subsidiary Guarantor, or of any stockholder of the Company, the Issuer or any Subsidiary Guarantor, shall not have any liability for any obligations of the Company, the Issuer or any Subsidiary Guarantor, either directly or through the Company, the Issuer or any Subsidiary Guarantor, as the case may be, under the Notes or this Indenture or for any claim based on, in respect of or by reason of such obligations or their creation whether by virtue of any rule of law, statute or constitutional provision or by the enforcement of any assessment or by any legal or equitable proceeding or otherwise. By accepting a Note, each Holder shall waive and release all and all such liability. The waiver and release shall be part of the consideration for the issue of the Notes.

80

Section 11.11 Successors. All agreements of the Company, the Issuer and any Subsidiary Guarantor in this Indenture and the Notes shall bind its successors. All agreements of either of the Trustees in this Indenture shall bind each of its respective successors.

Section 11.12 Multiple Originals. The parties may sign any number of copies of this Indenture. Each signed copy shall be an original, but all of them together represent the same agreement. The exchange of copies of this Indenture and of signature pages by facsimile or PDF transmission shall constitute effective execution and delivery of this Indenture as to the parties hereto and may be used in lieu of the original Indenture for all purposes. Signatures of all the parties hereto transmitted by facsimile or PDF shall be deemed to be their original signatures for all purposes other than the U.S. Trustee’s signature on the certificate of authentication on each Note.

Section 11.13 Table of Contents; Headings. The table of contents, cross reference sheet and headings of the Articles and Sections of this Indenture have been inserted for convenience of reference only, are not intended to be considered a part hereof and shall not modify or restrict any of the terms or provisions hereof.

Section 11.14 WAIVER OF TRIAL BY JURY. EACH PARTY HERETO, AND EACH HOLDER OF SECURITIES BY ITS ACCEPTANCE THEREOF, HEREBY IRREVOCABLY WAIVES, TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, ANY AND ALL RIGHT IT MAY HAVE TO TRIAL BY JURY IN ANY LEGAL PROCEEDING DIRECTLY OR INDIRECTLY ARISING OUT OF OR RELATING TO THIS INDENTURE, THE NOTES OR THE TRANSACTIONS CONTEMPLATED HEREBY OR THEREBY.

Section 11.15 Force Majeure. In no event shall either of the Trustees be responsible or liable for any failure or delay in the performance of their 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 Trustees shall use reasonable efforts that are consistent with accepted practices in the banking industry to resume performance as soon as practicable under the circumstances.

Section 11.16 USA Patriot Act Compliance. To help the government fight the funding of terrorism and money laundering activities, federal law requires all financial institutions to obtain, verify and record information that identifies each Person who opens an account. For a non-individual Person such as a business entity, a charity, a trust or other legal entity, the Trustees will ask for documentation to verify its formation and existence as a legal entity. The Trustees may also ask to see financial statements, licenses, identification and authorization documents from individuals claiming authority to represent the entity or other relevant documentation. The Company, the Issuer and the Subsidiary Guarantors agree to provide all such information and documentation as to themselves as requested by the U.S. Trustee to ensure compliance with federal law.

81

Section 11.17 Submission to Jurisdiction.

The Company and each Subsidiary Guarantor not organized in the United States shall appoint Corporation Service Company as its agent for service of process in any suit, action or proceeding with respect to this Indenture, the Notes, the Company Guarantee and the Subsidiary Guarantees and for actions brought under the U.S. federal or state securities laws brought in any U.S. federal or state court located in the Borough of Manhattan in the County and City of New York. The Company, the Issuer and each Subsidiary Guarantor irrevocably and unconditionally submit to the non-exclusive jurisdiction of the U.S. federal or state 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, the Company Guarantee and the Subsidiary Guarantees and for actions brought under the U.S. federal or state securities laws. Service of any process on Corporation Service Company in any such action (and written notice of such service to the Issuer) shall be effective service of process against the Company or any Subsidiary Guarantor not organized in the United States with respect to any such suit, action or proceeding. The Company, the Issuer and each Subsidiary Guarantor irrevocably and unconditionally waives any objection to the laying of venue of any such suit, action or proceeding brought in any such court and any claim that any such suit, action or proceeding has been brought in an inconvenient forum. A final judgment in any such suit, action or proceeding brought in any such court shall be conclusive and binding upon the Company, the Issuer and each Subsidiary Guarantor and may be enforced in any other courts to whose jurisdiction the Issuer is or may be subject, by suit upon judgment. The Company, the Issuer and each Subsidiary Guarantor further agrees that nothing herein shall affect any Holder’s right to effect service of process in any other manner permitted by law or bring a suit action or proceeding (including a proceeding for enforcement of a judgment) in any other court or jurisdiction in accordance with applicable law.

Section 11.18 Waiver of Immunity.

To the extent that each of the Company, the Issuer and the Subsidiary Guarantors, or any of their respective properties, assets or revenues may have or may hereafter become entitled to, or have attributed to each of the Company, the Issuer and the Subsidiary Guarantors, any right of immunity, on the grounds of sovereignty or otherwise, from any legal action, suit or proceeding, from the giving of any relief in any such legal action, suit or proceeding, from setoff or counterclaim, from the jurisdiction of any Canadian, New York state or U.S. federal court, from service of process, from attachment upon or prior to judgment, from attachment in aid of execution of judgment, or from execution of judgment, or other legal process or proceeding for the giving of any relief or for the enforcement of any judgment, in any such court in which proceedings may at any time be commenced, with respect to the obligations and liabilities of each of the Company, the Issuer and the Subsidiary Guarantors or any other matter under or arising out of or in connection with this Indenture, each of the Company, the Issuer and the Subsidiary Guarantors hereby irrevocably and unconditionally waives or will waive such right to the extent permitted by applicable law, and agrees not to plead or claim, any such immunity and consent to such relief and enforcement.

Section 11.19 Conversion of Currency.

82

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, the Issuer 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, the Issuer, 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, the Issuer’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 U.S. 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 U.S. 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, the Issuer and the Subsidiary Guarantors, jointly and severally, agrees, as a separate obligation and notwithstanding any such judgment, to indemnify the Holder and the U.S. 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 U.S. Trustee, as the case may be, such Holder or the U.S. Trustee, as the case may be, will pay the Company, the Issuer and the Subsidiary Guarantors, such excess; provided that such Holder or the U.S. Trustee, as the case may be, shall not have any obligation to pay any such excess as long as a Default under the Notes or this Indenture has occurred and is continuing or if the Company, the Issuer or the Subsidiary Guarantors shall have failed to pay any Holder or the U.S. Trustee any amounts then due and payable under such Note or this Indenture, in which case such excess may be applied by such Holder or the U.S. Trustee to such Obligations.

Section 11.20 OFAC Sanctions.

(a) Each of the Issuer and the Company covenants and represents that neither it nor any of its affiliates, subsidiaries, directors or officers are the target or subject of any sanctions enforced by the US Government, (including, the Office of Foreign Assets Control of the US Department of the Treasury (“OFAC”)), the United Nations Security Council, the European Union, Her Majesty’s Treasury, or other relevant sanctions authority (collectively “Sanctions”).

(b) Each of the Issuer and the Company covenants and represents that neither it nor any of its affiliates, subsidiaries, directors or officers will use any part of the proceeds received in connection with the Indenture or any other of the transaction documents (i) to fund or facilitate any activities of or business with any person who, at the time of such funding or facilitation, is the subject or target of Sanctions, (ii) to fund or facilitate any activities of or business with any country or territory that is the target or subject of Sanctions, or (iii) in any other manner that will result in a violation of Sanctions by any person.

[FORM OF REVERSE SIDE OF NOTE]

4.125% Senior Note due 2031

1. Interest

Open Text Holdings, Inc., a corporation organized under the laws of Delaware (such corporation, and its successors and assigns under the Indenture hereinafter referred to, being herein called the “Issuer”), promises to pay interest on the principal amount of this Note at the rate per annum shown above. The Issuer shall pay interest semiannually on June 1 and December 1 of each year. Interest on the Notes shall accrue from the most recent date to which interest has been paid or duly provided for or, if no interest has been paid or duly provided for, from November 24, 2021 until the principal hereof is due. Interest shall be computed on the basis of a 360-day year of twelve 30-day months.

For purposes of the Interest Act (Canada), whenever any interest or fee under the Notes or the 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 calendar year in which the period for which such interest or fee is payable (or compounded) ends, 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 the Indenture. The rates of interest stipulated in the Notes and the Indenture are intended to be nominal rates and not effective rates or yields.

2. Method of Payment

The Issuer shall pay interest on the Notes (except defaulted interest) to the Persons who are registered Holders at the close of business on the May 15 or November 15 preceding the interest payment date even if Notes are canceled after the record date and on or before the interest payment date. Holders must surrender Notes to a Paying Agent to collect principal payments. The Issuer shall pay principal, premium, if any, and interest in money of the United States of America that at the time of payment is legal tender for payment of public and private debts. Payments in respect of the Notes represented by a Global Note (including principal, premium, if any, and interest) shall be made by wire transfer of immediately available funds to the accounts specified by The Depository Trust Company or any successor Depositary. The Issuer shall make all payments in respect of a Definitive Registered Note (including principal, premium, if any, and interest), at the office of the Paying Agent, except that, at the option of the Issuer, payment of interest may be made by mailing a check to the registered address of each Holder thereof; provided, however, that payments on the Notes may also be made, in the case of a Holder of at least $1,000,000 aggregate principal amount of Notes, by wire transfer to a U.S. dollar account maintained by the payee with a bank in the United States if such Holder elects payment by wire transfer by giving written notice to the U.S. Trustee or the Paying Agent to such effect designating such account no later than 30 days immediately preceding the relevant due date for payment (or such other date as the U.S. Trustee may accept in its discretion).

3. Paying Agent and Registrar

A-7

Initially, The Bank of New York Mellon (the “U.S. Trustee”), shall act as Paying Agent and Registrar. The Issuer may appoint and change any Paying Agent or Registrar without notice. The Issuer or any of its domestically incorporated wholly owned Subsidiaries may act as Paying Agent (prior to an Event of Default) or Registrar.

4. Indenture

The Issuer issued the Notes under an Indenture dated as of November 24, 2021 (the “Indenture”), among the Issuer, Open Text Corporation (the “Company”), the Subsidiary Guarantors named therein and the Trustees. Terms defined in the Indenture and not defined herein have the meanings ascribed thereto in the Indenture. The Notes are subject to all terms and provisions of the Indenture and Holders (as defined in the Indenture) are referred to the Indenture for a statement of such terms and provisions.

The Notes are senior unsecured obligations of the Issuer. The Issuer shall be entitled to issue Additional Notes pursuant to Section 2.15 of the Indenture. The Original Notes (as defined in the Indenture) and any Additional Notes shall be treated as a single class for all purposes of the Indenture. The Indenture imposes certain limitations on the ability of the Company, the Issuer and its Subsidiaries to, among other things, create or incur Liens, and enter into certain Sale/Leaseback Transactions. The Indenture also imposes limitations on the ability of the Company, the Issuer and the Subsidiary Guarantors to consolidate, amalgamate or merge with or into any other Person or convey, transfer or lease all or substantially all its property.

To guarantee the due and punctual payment of the principal of, and interest on the Notes and all other amounts payable by the Issuer under the Indenture and the Notes when and as the same shall be due and payable, whether at maturity, by acceleration or otherwise, according to the terms of the Notes and the Indenture, the Company and the Subsidiary Guarantors have jointly and severally unconditionally guaranteed the Guaranteed Obligations on a senior unsecured basis pursuant to the terms of the Indenture.

5. Optional Redemption

Except as set forth in Section 3.5 of the Indenture and in the following paragraphs of this Section 5, the Notes shall not be redeemable at the option of the Issuer prior to December 1, 2026.

On and after December 1, 2026, the Issuer shall be entitled at its option on one or more occasions to redeem all or a portion of the Notes (which, for the avoidance of doubt, includes Additional Notes, if any) at the following redemption prices (expressed in percentages of principal amount on the redemption date), plus accrued and unpaid interest, if any, to the redemption date (subject to the right of Holders of record on the relevant record date to receive interest due on the relevant interest payment date), if redeemed during the 12-month period commencing on December 1 of the years set forth below:

A-8

In addition, at any time prior to December 1, 2024, the Issuer may at its option on one or more occasions redeem in an aggregate principal amount not to exceed 40.0% of the aggregate principal amount of the Notes (which, for the avoidance of doubt, includes Additional Notes, if any) originally issued at a redemption price (expressed as a percentage of principal amount) of 104.125%, plus accrued and unpaid interest, if any, to the redemption date (subject to the right of Holders of record on the relevant record date to receive interest due on the relevant interest payment date), with the net cash proceeds from one or more Qualified Equity Offerings; provided, however, that (a) at least 50% of such aggregate principal amount of Notes (excluding any Additional Notes, if any) originally issued under the Indenture remains outstanding immediately after the occurrence of each such redemption; and (b) each such redemption occurs within 90 days after the date of the related Qualified Equity Offering.

Prior to December 1, 2026, the Issuer shall be entitled at its option to redeem all or a portion of the Notes (which, for the avoidance of doubt, includes Additional Notes, if any) at a redemption price equal to 100% of the principal amount of the Notes plus the Applicable Premium as of, and accrued and unpaid interest, if any, to, the redemption date (subject to the right of Holders on the relevant record date to receive interest due on the relevant interest payment date).

Any redemption may, at the Issuer’s discretion, be subject to one or more conditions precedent, which will be set forth in the related notice of redemption, including, but not limited to, completion of a Qualified Equity Offering, other offering or financing or other transaction or event. In addition, if such redemption is subject to satisfaction of one or more conditions precedent, such notice will describe each such condition, and if applicable, will state that, in the Issuer’s discretion, the redemption date may be delayed until such time (provided, however, that any redemption date will not be more than 60 days after the date of the notice of redemption) as any or all such conditions will be satisfied, or such redemption may not occur and such notice may be rescinded in the event that any or all such conditions will not have been satisfied by the redemption date, or by the redemption date as so delayed. If any such condition precedent has not been satisfied, the Issuer will provide written notice to the U.S. Trustee prior to the close of business one Business Day prior to the redemption date. Upon receipt of such notice, the notice of redemption shall be rescinded or delayed, and the redemption of the Notes shall be rescinded or delayed as provided in such notice. Upon receipt, the U.S. Trustee shall provide such notice to each Holder of the Notes in the same manner in which the notice of redemption was given.

6. Sinking Fund

The Notes are not subject to any sinking fund.

7. Notice of Redemption

Notice of any redemption pursuant to Section 5 above shall be mailed (in the case of Definitive Registered Notes) by first-class mail (or otherwise delivered in accordance with the Applicable Procedures) at least 10 days but not more than 60 days before the redemption date to each Holder of Notes to be redeemed at his or her registered address, except that redemption notices may be mailed (or otherwise delivered in accordance with the Applicable Procedures) more than 60 days prior to the redemption date if the notice is issued in connection with a

A-9

defeasance of the Notes or a satisfaction and discharge of the Indenture. Any inadvertent defect in the notice of redemption, including an inadvertent failure to give notice, to any Holder selected for redemption shall not impair or affect the validity of the redemption of any other Note redeemed in accordance with provisions of the Indenture. Notes in denominations of $2,000 or less may be redeemed in whole but not in part.

If any Note is to be redeemed in part only, the notice of redemption that relates to that Note will state the portion of the principal amount thereof to be redeemed. We will issue a new Note in a principal amount equal to the unredeemed portion of the original Note in the name of the Holder upon cancellation of the original Note. Notes called for redemption become due on the date fixed for redemption. With respect to registered Notes issued in global form, the principal amount of such Note or Notes will be adjusted in accordance with the Applicable Procedures. Notes held in certificated form must be surrendered to the Paying Agent in order to collect the redemption price. Unless the Issuer defaults in the payment of the redemption price, on and after the redemption date, interest ceases to accrue on Notes or portions of them called for redemption.

8. Repurchase of Notes at the Option of Holders upon Change of Control Triggering Event

In accordance with Section 4.9 of the Indenture, the Issuer shall be required to offer to purchase Notes upon the occurrence of a Change of Control Triggering Event. Any Holder of Notes shall have the right, subject to certain conditions specified in the Indenture, to cause the Issuer to repurchase all or any part of the Notes of such Holder at a purchase price equal to 101.0% of the principal amount of the Notes to be repurchased plus accrued and unpaid interest, if any, to, but excluding, the date of repurchase (subject to the right of Holders of record on the relevant record date to receive interest due on the relevant interest payment date) as provided in, and subject to the terms of, the Indenture.

9. Denominations; Transfer; Exchange

The Notes are in registered form without coupons in denominations of $2,000 and whole multiples of $1,000 in excess thereof. A Holder may transfer or exchange Notes in accordance with the Indenture. Upon any transfer or exchange, the Registrar and the Trustees may require a Holder, among other things, to furnish appropriate endorsements or transfer documents and to pay any taxes required by law or permitted by the Indenture. The Registrar need not register the transfer of or exchange any Notes selected for redemption (except, in the case of a Note to be redeemed in part, the portion of the Note not to be redeemed) or to transfer or exchange any Notes for a period of 15 days prior to any date fixed for the redemption of such notes, for a period of 15 days immediately prior to the date fixed for selection of such Notes to be redeemed in part, for a period of 15 days prior to the record date with respect to any interest payment date applicable to such Notes; or which the Holder has tendered (and not withdrawn) for repurchase in connection with a Change of Control Offer.

10. Persons Deemed Owners

The registered Holder of this Note shall be treated as the owner of it for all purposes.

A-10

11. Unclaimed Money

If money for the payment of principal, interest, or Applicable Premium (if any) remains unclaimed for two years, the Trustees and the Paying Agent shall pay the money to the Issuer upon its written request unless an applicable abandoned property law designates another Person. After any such payment, Holders entitled to the money must look to the Issuer for payment as general creditors and the Trustees and the Paying Agent shall have no further liability with respect to such monies.

12. Discharge and Defeasance

Subject to certain conditions set forth in the Indenture, the Issuer at any time may terminate some of or all its obligations under the Notes and the Indenture if the Issuer deposits with the U.S. Trustee money or U.S. Government Obligations for the payment of principal of, and interest on, the Notes to redemption or maturity, as the case may be.
