"Attributable Debt" in respect of a sale and leaseback transaction means, at the time of determination, the present value of the obligation of the lessee for net rental payments during the remaining term of the lease included in such sale and leaseback transaction including any period for which such lease has been extended or may, at the option of the lessor, be extended. Such present value shall be calculated using a discount rate equal to the rate of interest implicit in such transaction, determined in accordance with IFRS. As used in the preceding sentence, the "net rental payments" under any lease for any such period shall mean the sum of rental and other payments required to be paid with respect to such period by the lessee thereunder, excluding any amounts required to be paid by such lessee on account of maintenance and repairs, insurance, taxes, assessments, water rates or similar charges. In the case of any lease that is terminable by the lessee upon payment of penalty, such net rental payment shall also include the amount of

such penalty, but no rent shall be considered as required to be paid under such lease subsequent to the first date upon which it may be so terminated.

“Bankruptcy Law” means Title 11, U.S. Code, the Bankruptcy and Insolvency Act (Canada), the Companies’ Creditors Arrangement Act (Canada), the Winding-Up and Restructuring Act (Canada), or any similar federal, state or provincial law of the United States or Canada or other insolvency law in the applicable jurisdictions for the relief of debtors that are insolvent or bankrupt from time to time in effect and affecting the rights of creditors generally.

The terms “Beneficially Owns,” “Beneficially Owned” and “Beneficial Ownership” have correlative meanings.

"Cash Equivalents" means:

(1) securities issued or directly and fully guaranteed or insured by (a) the federal government of the United States or Canada or any agency or instrumentality of the federal government of the United States or Canada (provided that the full faith and credit of the United States or Canada, in each case, is pledged in support of those securities) or (b) any foreign country whose sovereign debt has a rating of at least “A3” from Moody’s, “A-” from S&P or “A-” from Fitch, or any agency or instrumentality of such foreign country (provided that the full faith and credit of such foreign country is pledged in support of those securities), in each case having maturities of not more than two years from the date of acquisition;

For the avoidance of doubt, any items identified as Cash Equivalents under this definition (other than clause (15) above) will be deemed to be Cash Equivalents for all purposes under this indenture regardless of the treatment of such items under IFRS.

"Change of Control" means the occurrence of any of the following:

(1) the direct or indirect sale, lease, transfer, conveyance or other disposition (other than by way of merger, amalgamation or consolidation), in one or a series of related transactions, of all or substantially all of the properties or assets (including Capital Stock of the Restricted Subsidiaries) of the Parent or the Issuer and their Restricted Subsidiaries taken as a whole, to any "person" (as that term is used in Section 13(d)(3) of the Exchange Act); and

For the purposes of this definition, (a) no Change of Control shall be deemed to have occurred solely as a result of a transfer of equity interests or other assets, or the consummation of any transaction (including, without limitation, any merger, arrangement, amalgamation or consolidation), among the Parent and its Restricted Subsidiaries; (b) a Person shall not be deemed to have beneficial ownership of securities subject to a stock purchase agreement, merger, arrangement or amalgamation agreement or similar agreement until the consummation of the transactions contemplated by such agreement; and (c) to the extent that one or more regulatory

Notwithstanding the preceding or any provision of Section 13d-3 of the Exchange Act:

(a) a Person shall not be deemed to have Beneficial Ownership of Voting Stock (i) pursuant to a stock purchase agreement, merger, arrangement or amalgamation agreement or similar agreement until the consummation of the transactions contemplated by such agreement, (ii) as a result of the right to acquire Voting Stock (so long as such Person does not have the right to direct the voting of the Voting Stock subject to such right) or any veto power in connection with the acquisition or disposition of Voting Stock or (iii) as a result of any veto or approval rights in any joint venture agreement, shareholder agreement or other similar agreement;

(b) (i) a conversion of the Parent, the Issuer or any other Restricted Subsidiary from a limited partnership, corporation, limited liability company or other form of entity to a limited liability company, corporation, limited partnership or other form of entity or (ii) an exchange of all of the outstanding Equity Interests in one form of entity for Equity Interests in another form of entity shall not constitute a Change of Control, so long as immediately following such conversion or exchange the "persons" (as that term is used in Section 13(d)(3) of the Exchange Act) who Beneficially Owned the Capital Stock of the Issuer immediately prior to such transactions continue to Beneficially Own in the aggregate more than 50% of the Voting Stock of such new entity; and

(c) with respect to any Parent Entity, no person shall be deemed to be or become a Beneficial Owner of more than 50% of the total voting power of the Voting Stock of the Parent or the Issuer unless such person shall be or become a Beneficial Owner of more than 50% of the total voting power of the Voting Stock of such Parent Entity.

"Change of Control Triggering Event" means the occurrence of both a Change of Control and Rating Decline.

For the avoidance of doubt, if the Parent elects to use the Transaction Agreement Date as the applicable date of determination in accordance with the foregoing, (a) such election may not be revoked, (b) any fluctuation or change in the Consolidated Leverage Ratio, Fixed Charge Coverage Ratio, Consolidated Net Income, Consolidated Cash Flow or Consolidated Net Tangible Assets of the Parent, the target business, or assets to be acquired subsequent to the Transaction Agreement Date and prior to the consummation of such Limited Condition Transaction, will not be taken into account for purposes of determining whether any Investment, Restricted Payment, Indebtedness, Disqualified Stock, Preferred Stock or Lien that is being made, incurred or issued in connection with such Limited Condition Transaction is permitted to be made, incurred or issued or in connection with compliance by the Parent or any of the Restricted Subsidiaries with any other provision of this Indenture or the Notes or any other action or transaction undertaken in connection with such Limited Condition Transaction and (c) until such Limited Condition Transaction is consummated or the definitive agreements related thereto are terminated of the relevant notice revoked, such Limited Condition Transaction and all transactions proposed to be undertaken in connection therewith (including the making of any Restricted Payment, or Investments, or the incurrence of Indebtedness and Liens) will be given pro forma effect when determining compliance of other transactions (including the making of any Restricted Payment, or Investments, or the incurrence or issuance of Indebtedness, Disqualified Stock, Preferred Stock and Liens unrelated to such Investment, acquisition or repayment, repurchase or refinancing of Indebtedness) that are consummated after the Transaction Agreement Date and on or prior to the consummation of such Limited Condition Transaction and any such transactions (including any incurrence or issuance of Indebtedness, Disqualified Stock or Preferred Stock and the use of proceeds thereof) will be deemed to have occurred on the Transaction Agreement Date and outstanding thereafter for purposes of calculating any baskets or ratios under this Indenture

after the date of such agreement and before the consummation of such Limited Condition Transaction; provided that for purposes of any such calculation of the Fixed Charge Coverage Ratio, consolidated interest expense will be calculated using an assumed interest rate for the Indebtedness to be incurred in connection with such Limited Condition Transaction based on the indicative interest margin contained in any financing commitment documentation with respect to such Indebtedness or, if no such indicative interest margin exists, as reasonably determined by the Parent in good faith.

Notwithstanding anything herein to the contrary, if the Parent or any of its Restricted Subsidiaries (x) incurs Indebtedness, issues Disqualified Stock or Preferred Stock, creates Liens, makes Asset Sales, makes Investments, makes Restricted Payments, designates any Subsidiary as a Restricted Subsidiary or an Unrestricted Subsidiary or repays any Indebtedness, Disqualified Stock or Preferred Stock in connection with any Limited Condition Transaction under a ratio-based basket and (y) incurs Indebtedness, issues Disqualified Stock or Preferred Stock, creates Liens, makes Asset Sales, Investments or Restricted Payments, designates any Subsidiary as a Restricted Subsidiary or an Unrestricted Subsidiary or repays any Indebtedness, Disqualified Stock or Preferred Stock in connection with any Limited Condition Transaction under a non-ratio-based basket (which occurs within five (5) Business Days of the events in clause (x) above), then the applicable ratio will be calculated with respect to any such action under the applicable ratio-based basket without regard to any such action under such non-ratio-based basket made in connection with such Limited Condition Transaction.

In addition, compliance with any requirement relating to absence of Default or Event of Default may be determined as of the Transaction Agreement Date and not as of any later date as would otherwise be required under this Indenture.

In the event an item of Indebtedness, Disqualified Stock or Preferred Stock (or any portion thereof) is incurred or issued, any Lien is incurred or other transaction is undertaken on the same date that any other item of Indebtedness, Disqualified Stock or Preferred Stock (or any portion thereof) is incurred or issued, any other Lien is incurred or other transaction is undertaken on reliance on a ratio basket based on the Fixed Charge Coverage Ratio or the Consolidated Leverage Ratio then such ratio will be calculated with respect to such incurrence, issuance or other transaction without regard to any other incurrence, issuance or transaction. Each item of Indebtedness, Disqualified Stock or Preferred Stock that is incurred or issued, each Lien incurred and each other transaction undertaken will be deemed to have been incurred, issued or taken first, to the extent available, pursuant to the relevant Fixed Charge Coverage Ratio or Consolidated Leverage Ratio.

ARTICLE II

THE NOTES

Section 2.01 Form and Dating.

(a) General. The Notes and the Trustee’s certificate of authentication will be substantially in the form of Exhibit A hereto. The Notes may have notations, legends or endorsements required by law, stock exchange rule or usage. Each Note will be dated the date of its authentication. The Notes shall be in minimum denominations of $2,000 and integral multiples of $1,000 in excess thereof.

The terms and provisions contained in the Notes will constitute, and are hereby expressly made, a part of this Indenture and the Issuer, the Guarantors and the Trustee, by their execution and delivery of this Indenture, expressly agree to such terms and provisions and to be bound thereby. 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.

(b) Global Notes. Notes issued in global form will be substantially in the form of Exhibit A hereto (including the Global Note Legend thereon and the "Schedule of Exchanges of Interests in the Global Note" attached thereto). Notes issued in definitive form will be substantially in the form of Exhibit A hereto (but without the Global Note Legend thereon and without the "Schedule of Exchanges of Interests in the Global Note" attached thereto). Each Global Note will represent such of the outstanding Notes as will be specified therein and each shall provide that it represents the aggregate principal amount of outstanding Notes from time to time endorsed thereon and that the aggregate principal amount of outstanding Notes represented thereby may from time to time be reduced or increased, as appropriate, to reflect exchanges and redemptions. Any endorsement of a Global Note to reflect the amount of any increase or decrease in the aggregate principal amount of outstanding Notes represented thereby will be made by the Trustee or the Custodian, at the direction of the Trustee, in accordance with instructions given by the Holder thereof as required by Section 2.06 thereof.

Section 2.02 Execution and Authentication.

At least one Officer must sign the Notes for the Issuer by manual, electronic or facsimile signature.

If an Officer whose signature is on a Note no longer holds that office at the time a Note is authenticated, the Note will nevertheless be valid.

A Note will not be valid until authenticated by the manual or electronic signature of the Trustee. The signature will be conclusive evidence that the Note has been authenticated under this Indenture.

The Trustee will, upon receipt of a written order of the Issuer signed by an Officer of the Issuer (an "Authentication Order"), authenticate the Notes for original issue that may be validly issued under this Indenture, including any Additional Notes. The aggregate principal amount of Notes outstanding at any time may not exceed the aggregate principal amount of Notes authorized for issuance by the Issuer pursuant to one or more Authentication Orders, except as provided in Section 2.07 thereof.

The Trustee may appoint an authenticating agent acceptable to the Issuer to authenticate Notes. An authenticating agent may authenticate Notes whenever the Trustee may do so. Each reference in this Indenture to authentication by the Trustee includes authentication by such agent. An authenticating agent has the same rights as an Agent to deal with Holders or an Affiliate of the Issuer.

Section 2.03 Registrar and Paying Agent.

The Issuer will maintain an office or agency where Notes may be presented for registration of transfer or for exchange (“Registrar”) and an office or agency where Notes may be presented for payment (“Paying Agent”). The Registrar will keep a register of the Notes and of their transfer and exchange. The Issuer may appoint one or more co-registrars and one or more additional paying agents. The term “Registrar” includes any co-registrar and the term “Paying Agent” includes any additional paying agent. The Issuer may change any Paying Agent or Registrar without notice to any Holder. The Issuer will notify the Trustee in writing of the name and address of any Agent not a party to this Indenture. If the Issuer fails to appoint or maintain another entity as Registrar or Paying Agent, the Trustee shall act as such. The Parent or any of the Parent’s Subsidiaries may act as Paying Agent or Registrar.

The Issuer initially appoints The Depository Trust Company (“DTC”) to act as Depositary with respect to the Global Notes.

The Issuer initially appoints the Trustee to act as the Registrar and Paying Agent (at its offices indicated in the definition of Corporate Trust Office of the Trustee in Section 1.01 hereof) and to act as Custodian with respect to the Global Notes.

Section 2.04 Paying Agent to Hold Money in Trust.

The Issuer will require each Paying Agent other than the Trustee to agree in writing that the Paying Agent will hold in trust for the benefit of Holders or the Trustee all money held by the Paying Agent for the payment of principal of, premium on, if any, or interest on, the Notes, and will notify the Trustee of any default by the Issuer in making any such payment. While any such default continues, the Trustee may require a Paying Agent to pay all money held by it to the Trustee. The Issuer at any time may require a Paying Agent to pay all money held by it to the Trustee. Upon payment over to the Trustee, the Paying Agent (if other than the Issuer or a Subsidiary) will have no further liability for the money. If the Issuer or a Subsidiary acts as Paying Agent, it will segregate and hold in a separate trust fund for the benefit of the Holders all money held by it as Paying Agent. Upon any bankruptcy or reorganization proceedings relating to the Issuer, the Trustee will serve as Paying Agent for the Notes.

Section 2.05 Holder Lists.

The Trustee will preserve in as current a form as is reasonably practicable the most recent list available to it of the names and addresses of all Holders. If the Trustee is not the Registrar, the Issuer will furnish to the Trustee at least seven Business Days before each interest payment date and at such other times as the Trustee may request in writing, a list in such form and as of such date as the Trustee may reasonably require of the names and addresses of the Holders of Notes.

Section 2.06 Transfer and Exchange.

(a) Transfer and Exchange of Global Notes. A Global Note may not be transferred except as a whole by the Depositary to a nominee of the Depositary, by a nominee of the Depositary to the Depositary or to another nominee of the Depositary, or by the Depositary or any such nominee to a successor Depositary or a nominee of such successor Depositary. All Global Notes will be exchanged by the Issuer for Definitive Notes if:

(1) the Depositary (A) notifies the Issuer that it is unwilling or unable to continue to act as Depositary or has ceased to be a clearing agency registered under the Exchange Act and, in either case, a successor Depositary is not appointed by the Issuer within 90 days after the date of such notice from the Depositary;

(2) the Issuer, at its option but subject to the Depositary’s requirements, notifies the Trustee in writing that it elects to cause the issuance of the Definitive Notes; or

(3) there has occurred and is continuing an Event of Default, and the Depositary notifies the Trustee of its decision to exchange such Global Note for Definitive Notes.

Upon the occurrence of any of the preceding events in (1), (2) or (3) above, Definitive Notes shall be issued in such names as the Depositary shall instruct the Trustee. Global Notes also may be exchanged or replaced, in whole or in part, as provided in Sections 2.07 and 2.10 hereof. Every Note authenticated and delivered in exchange for, or in lieu of, a Global Note or any portion thereof, pursuant to this Section 2.06 or Section 2.07 or 2.10 hereof, shall be authenticated and delivered in the form of, and shall be, a Global Note. A Global Note may not be exchanged for another Note other than as provided in this Section 2.06(a), however, beneficial interests in a Global Note may be transferred and exchanged as provided in Section 2.06(b) or (c) hereof.

(b) Transfer and Exchange of Beneficial Interests in the Global Notes. The transfer and exchange of beneficial interests in the Global Notes will be effected through the Depositary, in accordance with the provisions of this Indenture and the Applicable Procedures.

Beneficial interests in any Restricted Global Note may be transferred to Persons who take delivery thereof in the form of a beneficial interest in the same Restricted Global Note in accordance with the transfer restrictions set forth in the Private Placement Legend; provided, however, that prior to the expiration of the Restricted Period, transfers of beneficial interests in the Regulation S Global Note may not be made to a U.S. Person or for the account or benefit of a U.S. Person (other than an Initial Purchaser). Beneficial interests in any Unrestricted Global Note may be transferred to Persons who take delivery thereof in the form of a beneficial interest in an Unrestricted Global Note. No written orders or instructions shall be required to be delivered to the Registrar to effect the transfers described in this Section 2.06(b)(1).

(2) All Other Transfers and Exchanges of Beneficial Interests in Global Notes. In connection with all transfers and exchanges of beneficial interests that are not

subject to Section 2.06(b)(1) above, the transferor of such beneficial interest must deliver to the Registrar either:

(i) a written order from a Participant or an Indirect Participant given to the Depositary in accordance with the Applicable Procedures directing the Depositary to credit or cause to be credited a beneficial interest in another Global Note in an amount equal to the beneficial interest to be transferred or exchanged; and

(ii) instructions given in accordance with the Applicable Procedures containing information regarding the Participant account to be credited with such increase; or

Upon satisfaction of all of the requirements for transfer or exchange of beneficial interests in Global Notes contained in this Indenture and the Notes or otherwise applicable under the Securities Act, the Trustee shall adjust the principal amount of the relevant Global Note(s) pursuant to Section 2.06(h) hereof.

(3) Transfer of Beneficial Interests to Another Restricted Global Note. A beneficial interest in any Restricted Global Note may be transferred to a Person who takes delivery thereof in the form of a beneficial interest in another Restricted Global Note if the transfer complies with the requirements of Section 2.06(b)(2) above and the Registrar receives the following:

If any such transfer is effected pursuant to subparagraph (A) or (B) above at a time when an Unrestricted Global Note has not yet been issued, the Issuer shall issue and, upon receipt of an Authentication Order in accordance with Section 2.02 thereof, the Trustee shall authenticate one or more Unrestricted Global Notes in an aggregate principal amount equal to the aggregate principal amount of beneficial interests transferred pursuant to subparagraph (A) or (B) above.

Beneficial interests in an Unrestricted Global Note cannot be exchanged for, or transferred to Persons who take delivery thereof in the form of, a beneficial interest in a Restricted Global Note.

(i) General Provisions Relating to Transfers and Exchanges.

(1) To permit registrations of transfers and exchanges, the Issuer will execute and the Trustee will authenticate Global Notes and Definitive Notes upon receipt of an Authentication Order in accordance with Section 2.02 hereof or at the Registrar’s request.

(2) No service charge will be made to a Holder of a beneficial interest in a Global Note or to a Holder of a Definitive Note for any registration of transfer or exchange, but the Issuer may require payment of a sum sufficient to cover any transfer tax or similar governmental charge payable in connection therewith (other than any such transfer taxes or similar governmental charge payable upon exchange or transfer pursuant to Sections 2.10, 3.06, 3.09, 4.10, 4.15 and 9.05 thereof).

(4) All Global Notes and Definitive Notes issued upon any registration of transfer or exchange of Global Notes or Definitive Notes will be the valid obligations of the Issuer, evidencing the same debt, and entitled to the same benefits under this Indenture, as the Global Notes or Definitive Notes surrendered upon such registration of transfer or exchange.

(5) Neither the Registrar nor the Issuer will be required:

(A) to issue, to register the transfer of or to exchange any Notes during a period beginning at the opening of business 15 days before the day of any selection of Notes for redemption under Section 3.02 hereof and ending at the close of business on the day of selection;

(B) to register the transfer of or to exchange any Note selected for redemption in whole or in part, except the unredeemed portion of any Note being redeemed in part; or

(7) The Trustee will authenticate Global Notes and Definitive Notes in accordance with the provisions of Section 2.02 thereof.

(8) All certifications, certificates and Opinions of Counsel required to be submitted to the Registrar pursuant to this Section 2.06 to effect a registration of transfer or exchange may be submitted by electronic image scan.

(9) Neither the Trustee nor any agent of the Trustee shall have any 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 any transfers of any interest in a Global Note between or among Participants or Beneficial Owners of any such interest) 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 thereof.

(10) The Trustee will have no responsibility or obligation to any Beneficial Owner of any interest in a Global Note, a Participant or any other Person with respect to the accuracy of the records of the Depositary or its nominee or of any Participant, with respect to any ownership interest in the Notes or with respect to the delivery to any Participant, Beneficial Owner or other Person (other than the Depositary or any Holder)

of any notice or the payment of any amount, under or with respect to the Notes. All notices and communications to be given to the Holders and all payments to be made to the Holders under the Notes and this Indenture will be given or made only to the registered Holders (which will be the Depositary or its nominee in the case of a Global Note). The rights of Beneficial Owners of any interest in a Global Note will be exercised only through the Procedures of the Depositary. The Trustee may rely and will be fully protected in relying on information furnished by the Depositary with respect to its Participants and any Beneficial Owners.

Section 2.07 Replacement Notes.

If any mutilated Note is surrendered to the Trustee or the Issuer and the Trustee receives evidence to its satisfaction of the destruction, loss or theft of any Note, the Issuer will issue and the Trustee, upon receipt of an Authentication Order, will authenticate a replacement Note if the Trustee's requirements are met. An indemnity bond must be supplied by the Holder that is sufficient in the judgment of each of the Trustee and the Issuer to protect the Issuer, the Trustee, any Agent and any authenticating agent from any loss that any of them may suffer if a Note is replaced. The Issuer may charge for its expenses in replacing a Note.

Every replacement Note is an additional obligation of the Issuer and will be entitled to all of the benefits of this Indenture equally and proportionately with all other Notes duly issued hereunder.

Section 2.08 Outstanding Notes.

The Notes outstanding at any time are all the Notes authenticated by the Trustee except for those canceled by it, those delivered to it for cancellation, those reductions in the interest in a Global Note effected by the Trustee in accordance with the provisions thereof, and those described in this Section 2.08 as not outstanding. Except as set forth in Section 2.09 thereof, a Note does not cease to be outstanding because the Issuer or an Affiliate of the Issuer holds the Note, however, Notes held by the Parent or a Subsidiary of the Parent shall not be deemed to be outstanding for purposes of Section 3.07(a) thereof.

If a Note is replaced pursuant to Section 2.07 hereof, it ceases to be outstanding unless the Trustee receives proof satisfactory to it that the replaced Note is held by a protected purchaser.

If the principal amount of any Note is considered paid under Section 4.01 hereof, it ceases to be outstanding and interest on it ceases to accrue.

If the Paying Agent (other than the Issuer, a Subsidiary or an Affiliate of any thereof) holds, by 10:00 a.m. Eastern Time on a redemption date or other maturity date, money sufficient to pay Notes payable on that date, then on and after that date such Notes will be deemed to be no longer outstanding and will cease to accrue interest.

Section 2.09 Treasury Notes.

In determining whether the Holders of the required principal amount of Notes have concurred in any direction, waiver or consent, Notes owned by the Issuer or any Guarantor, or by any Person directly or indirectly controlling or controlled by or under direct or indirect common control with the Issuer or any Guarantor, will be considered as though not outstanding, except that for the purposes of determining whether the Trustee will be protected in relying on any such direction, waiver or consent, only Notes that a Responsible Officer of the Trustee actually knows are so owned will be so disregarded.

Section 2.10 Temporary Notes.

Until certificates representing Notes are ready for delivery, the Issuer may prepare and the Trustee, upon receipt of an Authentication Order, will authenticate temporary Notes. Temporary Notes will be substantially in the form of certificated Notes but may have variations that the Issuer considers appropriate for temporary Notes and as may be reasonably acceptable to the Trustee. Without unreasonable delay, the Issuer will prepare and the Trustee will authenticate definitive Notes in exchange for temporary Notes.

Holders of temporary Notes will be entitled to all of the benefits of this Indenture.

Section 2.11 Cancellation.

The Issuer at any time may deliver Notes to the Trustee for cancellation. The Registrar and Paying Agent will forward to the Trustee any Notes surrendered to them for registration of transfer, exchange or payment. The Trustee and no one else will cancel all Notes surrendered for registration of transfer, exchange, payment, replacement or cancellation and will dispose of canceled Notes in accordance with the Trustee's customary procedures. Certification of the destruction of all canceled Notes will be delivered to the Issuer upon written request. The Issuer may not issue new Notes to replace Notes that it has paid or that have been delivered to the Trustee for cancellation.

Section 2.12 Defaulted Interest.

If the Issuer defaults in a payment of interest on the Notes, they will pay the defaulted interest in any lawful manner plus, to the extent lawful, interest payable on the defaulted interest,

to the Persons who are Holders on a subsequent special record date, in each case at the rate provided in the Notes and in Section 4.01 hereof, provided that no special record date shall be required with respect to a payment of interest that is made within the applicable grace period. The Issuer will notify the Trustee in writing of the amount of defaulted interest proposed to be paid on each Note and the date of the proposed payment. The Issuer will fix or cause to be fixed each such special record date and payment date; provided that no such special record date may be less than 10 days prior to the related payment date for such defaulted interest. At least 15 days before the special record date, the Issuer (or, upon the written request of the Issuer, the Trustee in the name and at the expense of the Issuer) will send to Holders a notice that states the special record date, the related payment date and the amount of such interest to be paid. The Trustee will not have any duty to determine whether any defaulted interest is payable or the amount thereof.

ARTICLE III

REDEMPTION AND PREPAYMENT

Section 3.01 Notices to Trustee.

If the Issuer elects to redeem Notes pursuant to the optional redemption provisions of Section 3.07 hereof, they must furnish to the Trustee, at least five Business Days prior to the giving of notice of redemption pursuant to Section 3.03 hereof, a notice in writing setting forth:

(1) the clause of this Indenture pursuant to which the redemption shall occur and the conditions precedent, if any, to the redemption;
(2) the redemption date;
(3) the principal amount of Notes to be redeemed; and
(4) the redemption price (if then determined and otherwise the method of determination).

The Trustee shall not be required make any calculations or verify or confirm any payment amounts with respect to any redemption.

Section 3.02 Selection of Notes to Be Redeemed.

If less than all of the Notes are to be redeemed at any time, the Trustee will select Notes for redemption on a pro rata basis (or, in the case of Notes issued in global form pursuant to Article 2 hereof, by such method as DTC may require), unless otherwise required by law.

In the event of partial redemption, the particular Notes to be redeemed will be selected, unless otherwise provided herein, not less than 10 nor more than 60 days prior to the redemption date by the Trustee from the outstanding Notes not previously called for redemption.

The Trustee will promptly notify the Issuer in writing of the Notes selected for redemption and, in the case of any Note selected for partial redemption, the principal amount thereof to be redeemed. Notes and portions of Notes selected will be in amounts of $2,000 or whole multiples of $1,000 in excess thereof; except that if all of the Notes of a Holder are to be

redeemed, the entire outstanding amount of Notes held by such Holder shall be redeemed. Except as provided in the preceding sentence, provisions of this Indenture that apply to Notes called for redemption also apply to portions of Notes called for redemption.

Section 3.03 Notice of Redemption.

(a) At least 10 (or in respect of a redemption made pursuant to Section 3.07(e), 15) days but not more than 60 days before a redemption date, the Issuer will send a notice of redemption to each Holder whose Notes are to be redeemed at its registered address, except that redemption notices may be sent more than 60 days prior to a redemption date if the notice is issued in connection with a defeasance of the Notes or a satisfaction and discharge of this Indenture pursuant to Article 8 or 11 hereof, respectively, or if the redemption date is delayed as described in Section 3.03(c).

The notice will identify the Notes, including CUSIP numbers, to be redeemed and will state:

(1) the redemption date;
(2) the redemption price (if then determined and otherwise the method of determination);
(3) if any Note is being redeemed in part, the portion of the principal amount of such Note to be redeemed and that, after the redemption date upon surrender of such Note, a new Note or Notes in principal amount equal to the unredeemed portion will be issued in the name of the Holder thereof upon cancellation of the original Note;
(4) the name and address of the Paying Agent;
(5) that Notes called for redemption must be surrendered to the Paying Agent to collect the redemption price;
(6) that, unless the Issuer defaults in making such redemption payment or the redemption is subject to conditions precedent that are not satisfied prior to the redemption date, interest on Notes or portions thereof called for redemption ceases to accrue on and after the redemption date;
(7) the paragraph of the Notes and/or Section of this Indenture pursuant to which the Notes called for redemption are being redeemed and the conditions precedent, if any, to the redemption; and
(8) that no representation is made as to the correctness or accuracy of the CUSIP number listed in such notice or printed on the Notes.

(b) At the Issuer's written request, the Trustee will give the notice of redemption in the Issuer's name and at the Issuer's expense; provided, however, that the notice delivered to the Trustee pursuant to Section 3.01 hereof requests that the Trustee give such notice

of redemption and sets forth the information to be stated in such notice as provided in the preceding paragraph.

(c) If such redemption or notice of 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 on one or more occasions either to a date specified in a subsequent notice to the Holders of the Notes or until such time (which date or time may be more than 60 days after the date the notice of redemption was mailed or delivered, including by electronic transmission) as any or all such conditions are satisfied (or waived by the Issuer in its sole discretion), or that such redemption may not occur and such notice may be rescinded in the event that any or all such conditions are not satisfied (or waived by the Issuer in its sole discretion) by the redemption date, or by the redemption date as so delayed, or that such notice may be rescinded at any time in the Issuer's discretion if as determined in good faith by the Issuer, any or all of such conditions will not be satisfied.

Section 3.04 Effect of Notice of Redemption.

Once notice of redemption is given in accordance with Section 3.03 hereof, Notes called for redemption without any condition precedent become irrevocably due and payable on the redemption date at the redemption price. Any redemption or notice of redemption may, at the Issuer's discretion, be subject to one or more conditions precedent. Any Note called for redemption subject to any conditions precedent, which conditions have become satisfied prior to the redemption date, shall become irrevocably due and payable on the redemption date at the redemption price.

Section 3.05 Deposit of Redemption Price.

No later than 10:00 a.m. Eastern Time on the redemption date, the Issuer will deposit with the Trustee or with the Paying Agent money sufficient to pay the redemption price of, and accrued interest on, all Notes to be redeemed on that date. The Trustee or the Paying Agent will as promptly as practicable return to the Issuer any money deposited with the Trustee or the Paying Agent by the Issuer in excess of the amounts necessary to pay the redemption price of, and accrued interest on, all Notes to be redeemed.

If the Issuer complies with the provisions of the preceding paragraph, on and after the redemption date, interest will cease to accrue on the Notes or the portions of Notes called for redemption. If a Note is redeemed on or after an interest record date but on or prior to the related interest payment date, then any accrued and unpaid interest shall be paid to the Person in whose name such Note was registered at the close of business on such record date. If any Note called for redemption is not so paid upon surrender for redemption because of the failure of the Issuer to comply with the preceding paragraph, interest shall be paid on the unpaid principal, from the redemption date until such principal is paid, and to the extent lawful on any interest not paid on such unpaid principal, in each case at the rate provided in the Notes and in Section 4.01 thereof.

Section 3.06 Notes Redeemed in Part.

Upon surrender of a Note that is redeemed in part, the Issuer will issue and, upon receipt of an Authentication Order, the Trustee will authenticate for the Holder at the expense of the Issuer a new Note equal in principal amount to the unredeemed portion of the Note surrendered.

Section 3.07 Optional Redemption.

Year	Percentages
2028	103.438%

Unless the Issuer defaults in the payment of the redemption price, interest will cease to accrue on the Notes or portions thereof called for redemption on the applicable redemption date.

(e) The Issuer may redeem all (but not a portion of) the Notes when permitted by, and pursuant to the conditions in, Section 4.15(d) hereof.

(f) The Issuer may, at its option at any time, redeem the Notes in whole but not in part, at 100.0% of the principal amount thereof, plus accrued and unpaid interest thereon, if any, to, but not including, the applicable redemption date (subject to the right of Holders of record on the relevant record date to receive interest due on an interest payment date that is on or prior to the applicable redemption date), and Additional Amounts, if any, in respect thereof, in the event any Guarantor has become or would become obligated to pay, on the next date on which any amount would be payable with respect to the Notes, any Additional Amounts as a result of:

(g) Any redemption pursuant to this Section 3.07 shall be made pursuant to the provisions of Sections 3.01 through 3.06 hereof.

Section 3.08 Mandatory Redemption. Other than set forth in Section 3.09, the Issuer is not required to make mandatory redemption or sinking fund payments with respect to the Notes.

Section 3.09 Offer to Purchase by Application of Excess Proceeds.

In the event that, pursuant to Section 4.10 hereof, the Issuer is required to commence an Asset Sale Offer, it will follow the procedures specified below.

The Asset Sale Offer shall be made to all Holders and all holders of other Senior Debt containing provisions similar to those set forth in this Indenture with respect to offers to

purchase, prepay or redeem with the proceeds of sales of assets. The Asset Sale Offer will remain open for a period of at least 20 Business Days following its commencement and not more than 30 Business Days, except to the extent that a longer period is required by applicable law (the "Offer Period"). No later than three Business Days after the termination of the Offer Period (the "Purchase Date"), the Issuer will apply all Excess Proceeds (the "Offer Amount") to the purchase of Notes and such other Senior Debt (on a pro rata basis based on the principal amount of Notes and such other Senior Debt surrendered, if applicable, except that any Notes represented by a Note in global form will be selected by such basis as DTC may require) or, if less than the Offer Amount has been tendered, all Notes and other Indebtedness tendered in response to the Asset Sale Offer. Payment for any Notes so purchased will be made in the same manner as interest payments are made.

If the Purchase Date is on or after an interest record date and on or before the related interest payment date, any accrued and unpaid interest will be paid to the Person in whose name a Note is registered at the close of business on such record date, and no additional interest will be payable to Holders who tender Notes pursuant to the Asset Sale Offer.

Upon the commencement of an Asset Sale Offer, the Issuer will send a notice to each of the Holders, with a copy to the Trustee. The notice will contain all instructions and materials necessary to enable such Holders to tender Notes pursuant to the Asset Sale Offer. The notice, which will govern the terms of the Asset Sale Offer, will state:

(1) that the Asset Sale Offer is being made pursuant to this Section 3.09 and Section 4.10 hereof and the length of time the Asset Sale Offer will remain open;
(2) the Offer Amount, the purchase price and the expiration date of the Asset Sale Offer;
(3) that any Note not tendered or accepted for payment will continue to accrue interest;
(4) that, unless the Issuer defaults in making such payment, any Note accepted for payment pursuant to the Asset Sale Offer will cease to accrue interest after the Purchase Date;
(5) that Holders electing to have a Note purchased pursuant to an Asset Sale Offer may elect to have Notes purchased in denominations of $2,000 or an integral multiple of $1,000 in excess thereof;
(6) that Holders electing to have Notes purchased pursuant to any Asset Sale Offer will be required to surrender the Note, with the form entitled “Option of Holder to Elect Purchase” attached to the Notes completed, or transfer by book-entry transfer, to the Issuer, a depositary, if appointed by the Issuer, or a Paying Agent at the address specified in the notice at least three days before the Purchase Date;
(7) that Holders will be entitled to withdraw their election if the Issuer, the Depositary or the Paying Agent, as the case may be, receives, not later than the expiration of the Offer Period, a telegram, electronic image scan or letter setting forth the name of

the Holder, the principal amount of the Note the Holder delivered for purchase and a statement that such Holder is withdrawing his election to have such Note purchased;

(8) that, if the aggregate principal amount of Notes surrendered by Holders thereof exceeds the Offer Amount allocated to the purchase of Notes in the Asset Sale Offer, the Trustee will select the Notes to be purchased on a pro rata basis (except that any Notes represented by a Global Note shall be selected by such method as DTC may require) based on the principal amount of Notes surrendered (with such adjustments as may be deemed appropriate by the Issuer so that only Notes in denominations of $2,000, or an integral multiple of $1,000 in excess thereof, will be purchased); and

(9) that Holders whose Notes were purchased only in part will be issued new Notes equal in principal amount to the unpurchased portion of the Notes surrendered (or transferred by book-entry transfer).

On or before the Purchase Date, the Issuer will, to the extent lawful, accept for payment, on a pro rata basis to the extent necessary, the Notes or portions thereof tendered pursuant to the Asset Sale Offer and required to be purchased pursuant to this Section 3.09 and Section 4.10, or if Notes in an aggregate principal amount less than the Offer Amount allocated to the purchase of Notes in an Asset Sale Offer have been tendered, all Notes tendered, and will deliver or cause to be delivered to the Trustee the Notes properly accepted together with an Officer’s Certificate stating that such Notes or portions thereof were accepted for payment by the Issuer in accordance with the terms of this Section 3.09. The Issuer, the depositary for the Asset Sale Offer or the Paying Agent, as the case may be, will promptly (but in any case not later than five days after the Purchase Date) mail or deliver to each tendering Holder an amount equal to the purchase price of the Notes tendered by such Holder and accepted by the Issuer for purchase, and the Issuer will promptly issue a new Note, and the Trustee, upon receipt of an Authentication Order, will authenticate and mail or deliver (or cause to be transferred by book entry) such new Note to such Holder, in a principal amount equal to any unpurchased portion of the Note surrendered. Any Note not so accepted shall be promptly mailed or delivered by the Issuer to the Holder thereof. The Issuer will publicly announce the results of the Asset Sale Offer on the Purchase Date.

ARTICLE IV COVENANTS

Section 4.01 Payment of Notes.

The Issuer will pay or cause to be paid the principal of, premium on, if any, and interest on the Notes on the dates and in the manner provided in the Notes. Principal, premium, if any, and interest will be considered paid on the date due if the Paying Agent, if other than the Parent or a Subsidiary of the Parent, holds as of 10:00 a.m. Eastern Time on the due date money deposited by the Issuer in immediately available funds and designated for and sufficient to pay all principal, premium, if any, and interest, if any, then due.

The Issuer will pay interest (including post-petition interest in any proceeding under any Bankruptcy Law) on overdue principal at a rate that is equal to the then applicable interest rate on the Notes to the extent lawful; it will pay interest (including post-petition interest in any

proceeding under any Bankruptcy Law) on overdue installments of interest (without regard to any applicable grace period), at the same rate to the extent lawful.

Section 4.02 Maintenance of Office or Agency.

The Issuer will maintain in the City and State of New York, an office or agency (which may be an office of the Trustee or an affiliate of the Trustee or Registrar) where Notes may be surrendered for payment, and it will maintain in the continental United States an office or agency where Notes may be surrendered for registration of transfer or for exchange and where notices and demands to or upon the Issuer in respect of the Notes and this Indenture may be served. The Issuer will give prompt written notice to the Trustee of any change in the location of such office or agency. If at any time the Issuer fails to maintain any such required office or agency or fail to furnish the Trustee with notice of a change in the address thereof, such presentations, surrenders, notices and demands (not including service of process) may be made or served at the Corporate Trust Office of the Trustee.

The Issuer may also from time to time designate one or more other offices or agencies where the Notes may be presented or surrendered for any or all such purposes and may from time to time rescind such designations; provided, however, that no such designation or rescission will in any manner relieve the Issuer of its obligation to maintain an office or agency in the City and State of New York for purposes of making payments on the Notes. The Issuer will give prompt written notice to the Trustee of any such designation or rescission and of any change in the location of any such other office or agency.

Section 4.03 Reports.

(a) So long as any Notes are outstanding, the Parent will provide to the Trustee and the Trustee shall deliver to the Holders, a copy of:

(1) on or prior to the later of (A) 90 days after the end of each fiscal year of the Parent or (B) the date on which the Parent would be required to file (after giving effect to any extension of time required for such filing granted by the applicable Canadian securities regulatory authorities) such information as a reporting issuer pursuant to Canadian Securities Legislation, annual consolidated financial statements of the Parent for such fiscal year (along with customary comparable results for the prior year), audited by the Parent's independent accountants and prepared in accordance with IFRS, and management's discussion and analysis ("MD&A") in respect of those audited annual consolidated financial statements that the Parent would be required to file as a reporting issuer in the Province of Alberta under Canadian Securities Legislation;

(2) on or prior to the later of (A) 45 days after the end of each of the first three fiscal quarters of each fiscal year of the Parent or (B) the date on which the Parent would be required to file (after giving effect to any extension of time required for such filing granted by the applicable Canadian securities regulatory authorities) such information as a reporting issuer pursuant to Canadian Securities Legislation, unaudited interim consolidated financial statements of the Parent in respect of the fiscal quarter or quarters then ended and the corresponding fiscal quarter or quarters from the prior year, and

MD&A in respect of those unaudited interim consolidated financial statements that the Parent would be required to file as a reporting issuer in the Province of Alberta under Canadian Securities Legislation; and

(3) so long as the Parent is a reporting issuer in any province of Canada, on or prior to the later of (A) the tenth day following an event that would give rise to a requirement for the Parent to file a material change report and (B) the date on which the Parent would be required to publicly file (after giving effect to any extension of time required for such filing granted by the applicable Canadian securities regulatory authorities) a material change report, in either case pursuant to Canadian Securities Legislation, such material change report.

(b) For purposes of this Section 4.03, "material change report" and "reporting issuer" have the meanings prescribed under applicable Canadian Securities Legislation.

(c) Any and all Defaults or Events of Default arising from a failure to furnish or file in a timely manner any financial information, document, information or report required by this Section 4.03 will be deemed cured (and the Parent will be deemed to be in compliance with this Section 4.03) upon furnishing or filing such financial statement, document, information or report as contemplated by this Section 4.03 (but without regard to the date on which such financial statement, document, information or report is so furnished or filed), and, if the Notes have been accelerated in accordance with the terms of this Indenture as a result of a failure to furnish or file such financial statement, document, information or report in a timely manner, upon such cure, such acceleration shall be deemed rescinded or canceled.

(d) In addition, the Parent will make available to the Holders of the Notes and to prospective investors, upon request, the information required to be delivered pursuant to Rule 144A(d)(4) under the Securities Act so long as the Notes are not freely transferable under Rule 144 under the Securities Act.

(e) The Parent will be deemed to have provided to the Trustee the financial statements, information, documents and reports, as applicable, referred to in Section 4.03(a)(1), (2) and (3) (each a "Financial Report") if the Parent has filed such Financial Report (including as part of a larger report) with the SEC via the EDGAR filing system (or any successor filing system) or on SEDAR+ (or any successor filing system).

(f) At any time that any of the Parent's Subsidiaries are Unrestricted Subsidiaries and any such Unrestricted Subsidiary or group of Unrestricted Subsidiaries, taken as a whole, constitutes a Significant Subsidiary of the Parent, then the quarterly and annual financial information required by Section 4.03(a)(1) or (2) will include a reasonably detailed presentation (which need not be audited or reviewed by the Parent's independent accounting firm or auditors), either on the face of the financial statements or in the footnotes thereto, or in the MD&A, of the financial condition and results of operations of the Parent and the Restricted Subsidiaries separate from the financial condition and results of operations of the Unrestricted Subsidiaries of the Parent.

(g) The Financial Reports to be provided as described above may be those of (i) the Parent, (ii) a Parent Entity or (iii) any other direct or indirect parent of the Parent, so long as, in the case of (iii), such direct or indirect parent of the Parent does not conduct, transact or otherwise engage, or commit to conduct, transact or otherwise engage, in any business or operations other than its direct or indirect ownership of all of the Equity Interests in, its management of the Parent and activities ancillary thereto, including corporate maintenance and regulatory compliance activities of such direct or indirect parent; provided that, if the financial information so furnished relates to a Parent Entity or any other direct or indirect parent of the Parent, the same is accompanied by a reasonably detailed description of the quantitative differences between the information relating to such parent, on the one hand, and the information relating to the Parent and its Restricted Subsidiaries on a standalone basis, on the other hand. Alternatively, the obligations of the Parent to deliver any Financial Report as described above will be deemed satisfied if a Parent Entity of the Parent has delivered to the Trustee (including by making them publicly available on EDGAR or SEDAR+) that Financial Report, that would otherwise be required to be provided in respect of the Parent, with respect to such Parent Entity; provided, however, that such obligations will only be deemed to be satisfied to the extent that the Parent would, by virtue of that Parent Entity's Financial Report, be exempt from the obligation to provide its own Financial Report to the applicable securities regulatory authorities pursuant to Section 13.4 of National Instrument 51-102 – Continuous Disclosure Obligations (“NI 51-102”) (or any similar successor provision of that instrument or any replacement therefor under Canadian Securities Legislation), and if the Parent would be required to provide any Financial Report separately from the reporting of the Parent Entity pursuant to Section 13.4 of NI 51-102 (or any successor or replacement provision therefor), the Parent will remain obligated to provide such Financial Report (and may not satisfy that obligation by providing such Financial Report with respect to its Parent Entity).

(h) It is understood that the Trustee shall have no duty or obligation whatsoever to monitor or confirm, on a continuing basis or otherwise, the Parent’s compliance with this Section 4.03, to determine whether or not such financial statements, information, documents or reports have been posted on any website or online data system or filed with the SEC via the EDGAR filing system (or any successor filing system) or on the SEDAR+ filing system (or any successor filing system) or to participate in any conference calls. The posting or delivery of any such financial statements, information documents or reports to the Trustee is for informational purposes only and the Trustee’s receipt of such shall not constitute actual or constructive knowledge or notice of any information contained therein or determinable from information contained therein, including the Parent’s compliance with any of the covenants under this Indenture (as to which the Trustee is entitled to rely exclusively on an Officer’s Certificate).

Section 4.04 Compliance Certificate.

(a) The Issuer or at its option, the Parent, shall deliver to the Trustee, within 90 days after the end of each fiscal year, beginning with the fiscal year ending December 31, 2025, an Officer’s Certificate stating that a review of the activities of the Parent and its Subsidiaries during the preceding fiscal year has been made under the supervision of the signing Officer with a view to determining whether the Parent and the Issuer have kept, observed, performed and fulfilled their obligations under this Indenture, and further stating, as to such Officer signing such certificate, that to the best of his or her knowledge the Parent and the Issuer

have kept, observed, performed and fulfilled each and every covenant contained in this Indenture and are not in default in the performance or observance of any of the terms, provisions and conditions of this Indenture (or, if a Default or Event of Default has occurred, describing all such Defaults or Events of Default of which he or she may have knowledge and what action the Parent and the Issuer are taking or propose to take with respect thereto).

(b) So long as any of the Notes are outstanding, the Issuer will deliver to the Trustee, within ten Business Days upon any Officer of the Parent or the Issuer becoming aware of any Default or Event of Default, a written statement specifying such Default or Event of Default and what action the Issuer is taking or propose to take with respect thereto.

Section 4.05 Taxes.

The Parent will pay, and will cause each of its Subsidiaries to pay, prior to delinquency, all material taxes, assessments, and governmental levies except such as are contested in good faith and by appropriate proceedings or where the failure to effect such payment is not adverse in any material respect to the Holders of the Notes.

Section 4.06 Stay, Extension and Usury Laws.

The Issuer and each of the Guarantors covenants (to the extent that it may lawfully do so) that it will not at any time insist upon, plead, or in any manner whatsoever claim or take the benefit or advantage of, any stay, extension or usury law wherever enacted, now or at any time hereafter in force, that may affect the covenants or the performance of this Indenture; and the Issuer and each of the Guarantors (to the extent that it may lawfully do so) hereby expressly waives all benefit or advantage of any such law, and covenants that it will not, by resort to any such law, hinder, delay or impede the execution of any power herein granted to the Trustee, but will suffer and permit the execution of every such power as though no such law has been enacted.

Section 4.07 Restricted Payments.

The Fair Market Value of any assets or securities that are required to be valued by this Section 4.07 will be determined by the management of the Parent. For purposes of determining compliance with this Section 4.07, in the event that a Restricted Payment or Permitted Investment at any time meets the criteria of one or more categories of Restricted Payments described in Section 4.07(b)(1) through (19), meets the criteria of one or more categories of the definition of Permitted Investments and/or is permitted pursuant to the first paragraph of this Section 4.07, the Parent will be permitted in its sole discretion to divide or classify (or later redivide or reclassify) in whole or in part such Restricted Payment or Permitted Investment in any manner that complies with this Section 4.07 at such time. For purposes of this Section 4.07, (i) unsecured Indebtedness of any Person will not be deemed to be subordinated in right of payment to secured Indebtedness of that Person merely because it is unsecured and (ii) Indebtedness of any Person will not be deemed to be subordinated in right of payment to Indebtedness of a Restricted Subsidiary of such Person merely because it is structurally subordinated thereto.

such Preferred Stock do not expressly restrict the ability of such Restricted Subsidiary to pay dividends or make distributions on its Capital Stock;

(2) make loans or advances to the Parent or any of its Restricted Subsidiaries (it being understood that the subordination of loans or advances made to the Parent or any of its Restricted Subsidiaries to other Indebtedness incurred by the Parent or any of its Restricted Subsidiaries shall not be deemed a restriction on the ability to make loans or advances); or

(7) any agreement for the sale or other disposition of a Restricted Subsidiary of the Parent that restricts distributions by that Restricted Subsidiary pending its sale or other disposition;

(11) any agreement or instrument relating to any property or assets acquired after the Issue Date, so long as such encumbrance or restriction relates only to the property or assets so acquired and is not and was not created in anticipation of such acquisitions;

(12) Hedging Contracts permitted from time to time under this Indenture;

(13) restrictions on cash, Cash Equivalents or other deposits or net worth imposed by customers under contracts entered into in the ordinary course of business;

(14) with respect to any Foreign Subsidiary, any encumbrance or restriction contained in the terms of any Indebtedness or any agreement pursuant to which such Indebtedness was incurred if either (a) the encumbrance or restriction applies only in the event of a payment default or a default with respect to a financial covenant in such Indebtedness or agreement or (b) the Parent determines that any such encumbrance or restriction will not materially affect the Issuer's ability to make principal or interest payments on the Notes, as determined in good faith by the Parent, whose determination shall be conclusive; and

(15) any other agreement governing Indebtedness of the Issuer or any Guarantor that is permitted to be incurred under Section 4.09; provided, however, that such encumbrances or restrictions are not materially more restrictive, taken as a whole, than those contained in this Indenture or the Credit Agreement, whichever is more restrictive, as in effect on the Issue Date, as determined in the good faith judgment of the Parent.

Section 4.09 Incurrence of Indebtedness and Issuance of Preferred Stock.

(a) The Parent will not, and will not permit any of its Restricted Subsidiaries to, directly or indirectly, create, incur, issue, assume, guarantee or otherwise become directly or

indirectly liable, contingently or otherwise, with respect to (collectively, “incur”) any Indebtedness (including Acquired Debt); the Parent will not, and will not permit any of its Restricted Subsidiaries to, issue any Disqualified Stock; and the Parent will not permit any of its Restricted Subsidiaries to issue any other Preferred Stock (other than Non-Economic Preferred Securities); provided, however, that the Parent, the Issuer and any Guarantor may incur Indebtedness (including Acquired Debt) or issue Disqualified Stock and the Issuer and any Restricted Subsidiary of the Parent may issue other Preferred Stock, if, for the Parent’s most recently ended Test Period immediately preceding the date on which such additional Indebtedness is incurred or such Disqualified Stock or other Preferred Stock are issued, the Fixed Charge Coverage Ratio would have been at least 2.00 to 1.00, determined on a pro forma basis (including a pro forma application of the net proceeds therefrom), as if the additional Indebtedness had been incurred or Disqualified Stock or other Preferred Stock had been issued, as the case may be, at the beginning of such Test Period.

(b) Section 4.09(a) will not prohibit the incurrence of any of the following items of Indebtedness (collectively, “Permitted Debt”) or the issuance of any Preferred Stock described in Section 4.09(b)(11) or (14):

(1) the incurrence by the Parent or any of its Restricted Subsidiaries of Indebtedness under one or more Credit Facilities, provided that, after giving effect to any such incurrence, the aggregate principal amount of all Indebtedness incurred under this Section 4.09(b)(1) (with letters of credit being deemed to have a principal amount equal to the maximum potential liability of the Parent and its Subsidiaries thereunder) and then outstanding does not exceed the greater of (a) $1,000.0 million and (b) 45.0% of the Parent’s Consolidated Net Tangible Assets; provided that any Indebtedness incurred under this Section 4.09(b)(1) may be extended, replaced, refunded, refinanced, renewed or defeased (including through successive extensions, replacements, refundings, refinancings, renewals and defeasances) with new Indebtedness so long as the principal amount (or accreted value, if applicable) of such new Indebtedness does not exceed the sum of (x) the principal amount (or accreted value, if applicable) of the Indebtedness being so extended, replaced, refunded, refinanced, renewed or defeased, plus (y) any accrued and unpaid interest on the Indebtedness being refinanced, plus (z) the amount of any tender premium or penalty or premium required to be paid under the terms of the instrument or documents governing such refinanced Indebtedness and any defeasance costs and any fees and expenses (including original issue discount, upfront fees or similar fees) incurred in connection with the incurrence of such new Indebtedness or the extension, replacement, refunding, refinancing, renewal or defeasance of such refinanced Indebtedness;

(2) the incurrence by the Parent or its Restricted Subsidiaries of the Existing Indebtedness;

(3) the incurrence by the Issuer and the Guarantors of Indebtedness represented by the Initial Notes and the related Guarantees to be issued on the Issue Date;

(4) the incurrence by the Parent or any of its Restricted Subsidiaries of Indebtedness represented by Finance Lease Obligations, Attributable Debt, mortgage

financings or purchase money obligations, in each case, incurred for the purpose of financing all or any part of the purchase price or cost of construction or improvement of property, plant or equipment used in the business of the Parent or such Restricted Subsidiary (together with improvements, additions, accessions and contractual rights relating primarily thereto), including all Permitted Refinancing Indebtedness incurred to extend, refinance, renew, replace, defease or refund any Indebtedness incurred pursuant to this Section 4.09(b)(4), provided that after giving effect to any such incurrence, the principal amount of all Indebtedness incurred pursuant to this Section 4.09(b)(4) and then outstanding does not exceed an amount equal to the greater of (a) $120.0 million and (b) 5.00% of the Parent’s Consolidated Net Tangible Assets;

(5) the incurrence by the Parent or any of its Restricted Subsidiaries of Indebtedness to a customer to finance the acquisition of any equipment necessary for the Parent or such Restricted Subsidiary to perform services for such customer in the ordinary course of business;

(6) the incurrence by the Parent or any of its Restricted Subsidiaries of Permitted Refinancing Indebtedness in exchange for, or the net proceeds of which are used to, extend, refinance, renew, replace, defease or refund Indebtedness of the Parent or any of its Restricted Subsidiaries (other than intercompany Indebtedness), in each case, that was permitted by this Indenture to be incurred under Section 4.09(a) or Section 4.09(b) (2), (3) or (14) or this Section 4.09(b)(6);

(7) the incurrence by the Parent or any of its Restricted Subsidiaries of intercompany Indebtedness between or among the Parent and any of its Restricted Subsidiaries; provided, however, that:

(A) if the Issuer is the obligor on such Indebtedness and a Guarantor is not the obligee, such Indebtedness must be expressly subordinated to the prior payment in full in cash of all Obligations with respect to the Notes, or if a Guarantor is the obligor on such Indebtedness and neither the Issuer nor another Guarantor is the obligee, such Indebtedness must be expressly subordinated to the prior payment in full in cash of all Obligations with respect to the Guarantee of such Guarantor, except, in any case, in respect of intercompany Indebtedness incurred in the ordinary course of business in connection with the cash management operations of the Parent and its Restricted Subsidiaries; and

(B) (i) any subsequent issuance or transfer of Equity Interests that results in any such Indebtedness being held by a Person other than the Parent or a Restricted Subsidiary of the Parent and (ii) any sale or other transfer of any such Indebtedness to a Person that is neither the Parent nor a Restricted Subsidiary of the Parent will be deemed, in each case, to constitute an incurrence of such Indebtedness by the Parent or such Restricted Subsidiary, as the case may be, that was not permitted by this Section 4.09(b)(7);

(8) the incurrence by the Parent or any of its Restricted Subsidiaries of obligations under Hedging Contracts in the ordinary course of business or consistent with past practice and not for speculative purposes;

(9) the guarantee by the Parent or any of its Restricted Subsidiaries of Indebtedness of the Parent or any of its Restricted Subsidiaries that was permitted to be incurred by another provision of this Section 4.09; provided that in the event such Indebtedness being guaranteed is subordinated in right of payment to the Notes or the Guarantees, then the guarantee shall be subordinated in right of payment to the Notes or the Guarantees, as the case may be;

(10) the incurrence by the Parent or any of its Restricted Subsidiaries of Indebtedness in respect of (a) workers' compensation claims, bank guarantees, warehouse receipt or similar facilities, property, casualty or liability insurance, take-or-pay obligations in supply arrangements, self-insurance obligations or completion, bid, performance, surety, customs, appeals and advance payment bonds, standby letters of credit or surety and similar obligations issued for the account of the Parent and any of its Restricted Subsidiaries in the ordinary course of business or in connection with the enforcement of rights or claims of the Parent or any of its Restricted Subsidiaries or in connection with judgments that do not result in a Default or an Event of Default, including guarantees or obligations of the Parent or any of its Restricted Subsidiaries with respect to letters of credit supporting such obligations (in each case other than an obligation for money borrowed) and (b) netting, overdraft protection and other arrangements arising under standard business terms of any bank at which the Parent or any Restricted Subsidiary maintains an overdraft, cash pooling or other similar facility or arrangement;

(11) the issuance by any of the Parent's Restricted Subsidiaries to the Parent or to any of its Restricted Subsidiaries of any Preferred Stock; provided, however, that:

(A) any subsequent issuance or transfer of Equity Interests that results in any such Preferred Stock being held by a Person other than the Parent or a Restricted Subsidiary of the Parent, and

(B) any sale or other transfer of any such Preferred Stock to a Person that is not either the Parent or a Restricted Subsidiary of the Parent shall be deemed, in each case, to constitute an issuance (as of the date of such issuance, sale or transfer) of such Preferred Stock by such Restricted Subsidiary that was not permitted by this Section 4.09(b)(11);

(12) the incurrence by the Parent or any of its Restricted Subsidiaries of liability in respect of the Indebtedness of any Unrestricted Subsidiary of the Parent or any Joint Venture but only to the extent that such liability is the result of the Parent's or any such Restricted Subsidiary's being a general partner of such Unrestricted Subsidiary or Joint Venture and not as guarantor of such Indebtedness and provided that, after giving effect to any such incurrence, the aggregate principal amount of all Indebtedness incurred under this Section 4.09(b)(12) and then outstanding does not exceed $25.0 million;

(13) the incurrence by the Parent or any of its Restricted Subsidiaries of Permitted Acquisition Indebtedness;

(14) the incurrence by the Parent or any of its Restricted Subsidiaries of additional Indebtedness, provided that, after giving effect to any such incurrence, the aggregate principal amount of all Indebtedness incurred under this Section 4.09(b)(14) and then outstanding does not exceed an amount equal to the greater of (a) $120.0 million and (b) 5.00% of the Parent’s Consolidated Net Tangible Assets, and any Permitted Refinancing Indebtedness in respect thereof;

(15) the incurrence by the Parent or any of its Restricted Subsidiaries of (i) Indebtedness representing deferred compensation to directors, officers, members of management or employees of the Parent or any of its Restricted Subsidiaries and incurred in the ordinary course of business and (ii) Indebtedness consisting of promissory notes issued by the Parent or any of its Restricted Subsidiaries to any current or former employee, director or consultant of the Parent (or any direct or indirect parent of the Parent) or any of its Restricted Subsidiaries (or permitted transferees, assigns, spouses or former spouses, estates or heirs of such employee, director or consultant), to finance the purchase or redemption of Equity Interests of the Parent (or any direct or indirect parent of the Parent) that is permitted under Section 4.07;

(16) the incurrence by the Parent or any of its Restricted Subsidiaries of Indebtedness arising in connection with endorsement of instruments for deposit in the ordinary course of business;

(17) the incurrence by the Parent or any of its Restricted Subsidiaries of any obligation, or guarantee of any obligation, to reimburse or indemnify a Person extending credit to customers of the Parent or any of its Restricted Subsidiaries incurred in the ordinary course of business or consistent with past practice for all or any portion of the amounts payable by such customers to the Persons extending such credit;

(18) the incurrence of Indebtedness consisting of obligations for indemnification, adjustment of purchase price, earnouts or similar obligations, in each case, incurred or assumed in connection with any Investment or any acquisition or disposition of any business, assets or a Subsidiary, other than guarantees of Indebtedness incurred by any Person acquiring all or any portion of such business, assets or a Subsidiary for the purpose of financing such acquisition; and

(19) Convertible Securities issued by the Parent.

For purposes of determining compliance with this Section 4.09:

(1) in the event that an item of Indebtedness (including Acquired Debt), Disqualified Stock or other Preferred Stock meets the criteria of more than one of the categories of Permitted Debt described in Section 4.09(b)(1) through (19) above, or is entitled to be incurred or issued pursuant to Section 4.09(a), the Parent will be permitted to classify (or later classify or reclassify in whole or in part in its sole discretion) such item of Indebtedness, Disqualified Stock or other Preferred Stock, as the case may be, in

any manner that complies with this Section 4.09. Any Indebtedness under Credit Facilities on the Issue Date shall be considered incurred under Section 4.09(b)(1) and may not be reclassified. The principal amount of Indebtedness outstanding under any clause of this Section 4.09 shall be determined after giving effect to the application of proceeds of any Indebtedness incurred to refinance any such Indebtedness;

(2) Any Indebtedness incurred pursuant to Sections 4.09(b)(2) through (19) above shall cease to be deemed incurred or outstanding for purposes of such clause but shall be deemed incurred pursuant to the Fixed Charge Coverage Ratio test set forth in Section 4.09(a) from and after the first date on which the Parent or its Restricted Subsidiaries could have incurred such Indebtedness pursuant to the Fixed Charge Coverage Ratio test set forth Section 4.09(a) without reliance on such clause;

(3) For the avoidance of doubt, Indebtedness permitted by this Section 4.09 need not be permitted solely by reference to one provision permitting such Indebtedness but may be permitted in part by one such provision and in part by one or more other provisions of this Section 4.09 permitting such Indebtedness;

(4) The amount of Indebtedness issued at a price that is less than the principal amount thereof will be equal to the amount of the liability in respect thereof determined in accordance with IFRS; and

(5) The accrual of interest, the accretion of accreted value, the accretion or amortization of original issue discount, the payment of interest on any Indebtedness in the form of additional Indebtedness with the same terms, the accretion of liquidation preference, increases in the amount of Indebtedness outstanding solely as a result of fluctuations in the exchange rate of currencies and the payment of dividends on Disqualified Stock or other Preferred Stock in the form of additional shares of the same class of Disqualified Stock or other Preferred Stock, as the case may be, will not be deemed to be an incurrence of Indebtedness or an issuance of Disqualified Stock or other Preferred Stock for purposes of this Section 4.09, provided, in each such case, that the amount thereof is included in Fixed Charges of the Parent as accrued.

Unsecured Indebtedness of any Person will not be deemed to be subordinated in right of payment to secured Indebtedness of that Person merely because it is unsecured and Indebtedness of the Parent will not be deemed to be subordinated in right of payment to Indebtedness of a Restricted Subsidiary merely because it is structurally subordinated thereto. Further, the accounting reclassification of any obligation of the Parent or any of its Restricted Subsidiaries as Indebtedness will not be deemed an incurrence of Indebtedness for purposes of this Section 4.09.

For purposes of determining compliance with any U.S. dollar-denominated restriction on the incurrence of Indebtedness, the U.S. dollar-equivalent principal amount of Indebtedness denominated in a foreign currency shall be calculated based on the relevant currency exchange rate in effect on the date such Indebtedness was incurred, in the case of term Indebtedness, or first committed, in the case of revolving credit Indebtedness; provided that if such Indebtedness is incurred to refinance other Indebtedness denominated in a foreign currency, and such refinancing would cause the applicable U.S. dollar-denominated restriction to be exceeded if

calculated at the relevant currency exchange rate in effect on the date of such refinancing, such U.S. dollar-denominated restriction shall be deemed not to have been exceeded so long as the principal amount of such refinancing Indebtedness does not exceed the principal amount of such Indebtedness being refinanced. Notwithstanding any other provision of this Section 4.09, the maximum amount of Indebtedness that the Parent and its Restricted Subsidiaries may incur pursuant to this Section 4.09 shall not be deemed to be exceeded solely as a result of fluctuations in the exchange rate of currencies. The principal amount of any Permitted Refinancing Indebtedness, if incurred in a different currency from the Indebtedness being refinanced, shall be calculated based on the currency exchange rate applicable to the currencies in which such Permitted Refinancing Indebtedness is denominated that is in effect on the date of such refinancing.

Section 4.10 Asset Sales.

The Parent will not, and will not permit any of its Restricted Subsidiaries to, consummate an Asset Sale unless:

(1) the Parent (or a Restricted Subsidiary of the Parent, as the case may be) receives consideration at the time of the Asset Sale at least equal to the Fair Market Value (measured as of the date of the definitive agreement with respect to such Asset Sale) of the assets or Equity Interests issued or sold or otherwise disposed of; and

(2) at least 75% of the aggregate consideration received by the Parent and its Restricted Subsidiaries in the Asset Sale and all other Asset Sales since the Issue Date is in the form of cash, Cash Equivalents, Additional Assets or a combination thereof (collectively, "Asset Sale Consideration"). For purposes of this Section 4.10, each of the following will be deemed to be Asset Sale Consideration:

(A) any liabilities (excluding contingent liabilities), as shown on the Parent's most recent consolidated balance sheet (or if incurred subsequent to such balance sheet date, such liabilities that would have been reflected on such balance sheet or notes thereto if such incurrence had taken place on or prior to such balance sheet date, as determined in good faith by the Parent), of the Parent or any of its Restricted Subsidiaries (other than contingent liabilities and liabilities that are by their terms subordinated to the Notes or any Guarantee) that are (x) assumed by the transferee of any such assets pursuant to a customary novation agreement that releases the Parent or such Restricted Subsidiary from further liability or (y) otherwise cancelled or terminated in connection with the transaction with such transferee (other than intercompany Indebtedness owed to the Parent or a Restricted Subsidiary);

(B) any securities, notes or other obligations received by the Parent or any of its Restricted Subsidiaries from such transferee that are, within 180 days after the Asset Sale, converted by the Parent or such Restricted Subsidiary into cash, to the extent of the cash received in that conversion;

(C) any Designated Non-cash Consideration received by the Parent or any of its Restricted Subsidiaries in such Asset Sale having an aggregate Fair Market Value, taken together with all other Designated Non-cash Consideration received since the Issue Date pursuant to this clause (2)(C) that at the time has not been converted to cash, not to exceed an amount equal to the greater of (x) $75.0 million and (y) 3.00% of the Parent’s Consolidated Net Tangible Assets, with the Fair Market Value of each item of Designated Non-cash Consideration being measured at the time received and without giving effect to subsequent changes in value; and

(D) Indebtedness of any Restricted Subsidiary that ceases to be a Restricted Subsidiary as a result of such Asset Sale (other than intercompany debt owed to the Parent or a Restricted Subsidiary), to the extent such Indebtedness becomes Non-Recourse Debt.

Within 365 days after the receipt of any Net Proceeds from an Asset Sale (such period, the “Asset Sale Proceeds Application Period”), the Parent or any Restricted Subsidiary may apply an amount equal to those Net Proceeds at its option to any combination of the following:

(1) to repay, purchase, redeem or otherwise retire Senior Debt;

(2) to acquire Additional Assets;

(3) to acquire a majority of the Voting Stock of a Person primarily engaged in a Permitted Business; or

(4) to make capital expenditures.

The requirement of clause (2), (3) or (4) of the preceding paragraph of this Section 4.10 shall be deemed to be satisfied if a bona fide binding contract committing to make the investment, acquisition or expenditure referred to therein is entered into by the Parent or any of its Restricted Subsidiaries with a Person other than an Affiliate of the Parent within the time period specified in the preceding paragraph and such Net Proceeds are subsequently applied in accordance with such contract within six months following the date such agreement is entered into.

Pending the final application of any Net Proceeds, the Parent or any Restricted Subsidiary may temporarily reduce revolving credit borrowings or otherwise invest the Net Proceeds in any manner that is not prohibited by this Indenture. To the extent the amount applied as provided in the preceding paragraph of this Section 4.10 is less than the amount of Net Proceeds, the amount that is not so applied will constitute “Excess Proceeds.”

On the 366th day after the Asset Sale (or at the Issuer’s option, any earlier date), if the aggregate amount of Excess Proceeds then exceeds $35.0 million, within 30 days thereafter the Issuer will make an Asset Sale offer (an “Asset Sale Offer”) to all Holders of Notes (with a copy to the Trustee), and all holders of other Senior Debt containing provisions similar to those set forth in this Section 4.10 with respect to offers to purchase, prepay or redeem with the proceeds of sales of assets, to purchase, prepay or redeem, on a pro rata basis (except that Notes

represented by a Note in global form will be selected by such method as DTC may require), the maximum principal amount of Notes and such other Senior Debt that may be purchased, prepaid or redeemed out of the Excess Proceeds. The offer price in any Asset Sale Offer will be equal to 100% of the principal amount thereof plus accrued and unpaid interest (and Additional Amounts), if any, to the date of settlement, subject to the right of Holders of record on the relevant record date to receive interest due on an interest payment date that is on or prior to the date of settlement, and will be payable in cash. If any Excess Proceeds remain after consumption of an Asset Sale Offer, the Parent or any of its Restricted Subsidiaries may use those Excess Proceeds for any purpose not otherwise prohibited by this Indenture. If the aggregate principal amount of Notes and such other Senior Debt tendered into (or to be prepaid or redeemed in connection with) such Asset Sale Offer exceeds the amount of Excess Proceeds, the Excess Proceeds will be allocated to the purchase of Notes and such other Indebtedness on a pro rata basis (except that any Notes represented by a Note in global form will be selected by such method as DTC may require). The Parent may satisfy the foregoing obligation with respect to any Net Proceeds from an Asset Sale by making an Asset Sale Offer with respect to the amount of all or a part of the available Net Proceeds in advance of being required to do so by this Indenture. Upon completion of each Asset Sale Offer, the amount of Excess Proceeds will be reset at zero.

Notwithstanding clauses (1) through (4) of the second paragraph of this Section 4.10, to the extent that repatriating any or all of the Asset Sale Consideration from any Asset Sale by a Foreign Subsidiary (x) would result in material adverse tax consequences to the Parent or any of its Subsidiaries or (y) is prohibited or delayed by applicable local law from being repatriated to the United States or Canada (in the case of the foregoing clauses (x) and (y), as reasonably determined by the Parent in good faith which determination shall be conclusive), the portion of such Asset Sale Consideration so affected will not be required to be applied in compliance with clauses (1) through (4) of the second paragraph of this Section 4.10, and such amounts may be retained by the applicable Foreign Subsidiary; provided that, in the case of clause (y), the Parent shall take commercially reasonable efforts to cause the applicable Foreign Subsidiary to take all actions reasonably required by the applicable local law, applicable organizational impediments or other impediment to permit such repatriation, and, if such repatriation of any of such affected Asset Sale Consideration can be achieved such repatriation will be promptly effected and such repatriated Asset Sale Consideration will be applied (whether or not repatriation actually occurs) in compliance with clauses (1) through (4) of the second paragraph of this Section 4.10. The time periods set forth in this Section 4.10 with respect to an Asset Sale by a Foreign Subsidiary shall not start until such time as the Asset Sale Consideration may be repatriated whether or not such repatriation actually occurs.

Provisions hereunder relating to the Parent's obligation to make an offer to repurchase the Notes as a result of an Asset Sale may be waived or modified with the written consent of the Holders of a majority in principal amount of the then outstanding Notes.

The Issuer will comply with the requirements of Rule 14e-1 under the Exchange Act and any other securities laws and regulations thereunder to the extent those laws and regulations are applicable in connection with each repurchase of Notes pursuant to an Asset Sale Offer. To the extent that the provisions of any securities laws or regulations conflict with Section 3.09 or this Section 4.10, the Issuer will comply with the applicable securities laws and regulations and will

not be deemed to have breached its obligations under Section 3.09 or this Section 4.10 by virtue of such conflict.

Section 4.11 Transactions with Affiliates.

(a) The Parent will not, and will not permit any of its Restricted Subsidiaries to, make any payment to, or sell, lease, transfer or otherwise dispose of any of its properties or assets to, or purchase any property or assets from, or enter into or make or amend any transaction, contract, agreement, understanding, loan, advance or guarantee with, or for the benefit of, any Affiliate (each, an “Affiliate Transaction”), involving aggregate payments or consideration in excess of $25.0 million unless:

(1) the Affiliate Transaction is on terms (taken as a whole) that are not materially less favorable to the Parent or the relevant Restricted Subsidiary than those that would have been obtained in a comparable transaction by the Parent or such Restricted Subsidiary with an unrelated Person or, if in the good faith judgment of the Board of Directors no comparable transaction is available with which to compare such Affiliate Transaction, such Affiliate Transaction is otherwise fair to the Parent or such Restricted Subsidiary from a financial point of view; and

(2) the Parent delivers to the Trustee, with respect to any Affiliate Transaction or series of related Affiliate Transactions involving aggregate consideration in excess of $75.0 million, an Officer’s Certificate certifying that such Affiliate Transaction or series of related Affiliate Transactions complies with this Section 4.11 and that such Affiliate Transaction or series of related Affiliate Transactions has been approved by a majority of the disinterested members of the Board of Directors of the Parent.

(b) The following items will not be deemed to be Affiliate Transactions and, therefore, will not be subject to Section 4.11(a) hereof:

(1) any employment agreement, customary benefit program or arrangement, equity award, equity option or equity appreciation agreement or plan entered into by the Parent or any of its Restricted Subsidiaries with or for the benefit of officers, directors or employees of the Parent or any of its Restricted Subsidiaries in the ordinary course of business;

(2) transactions between or among any of the Parent and its Restricted Subsidiaries, including between any Restricted Subsidiaries;

(3) transactions with a Person (other than an Unrestricted Subsidiary of the Parent) that is an Affiliate of the Parent solely because the Parent owns, directly or through one of its Restricted Subsidiaries, an Equity Interest in such Person;

(4) customary compensation, indemnification and other benefits made available to officers, directors or employees of the Parent or any of its Restricted Subsidiaries, including reimbursement or advancement of out-of-pocket expenses and provisions of officers’ and directors’ liability insurance;

(5) issuances, transfers or sales of Equity Interests (other than Disqualified Stock) to, or receipt of capital contributions from, Affiliates of the Parent;

(6) (a) Permitted Investments or (b) Restricted Payments that are permitted by Section 4.07 hereof;

(7) transactions with customers, clients, suppliers, or purchasers or sellers of goods or services, in each case in the ordinary course of business that, in the good faith judgment of the executive officers of the Parent, are fair to the Parent and its Restricted Subsidiaries, or are on terms at least as favorable as might reasonably have been obtained at such time from an unaffiliated Person;

(8) any transaction in which the Parent or any of its Restricted Subsidiaries, as the case may be, delivers to the Trustee a letter from an accounting, appraisal or investment banking firm of national standing in the United States or Canada stating that such transaction is fair to the Parent or such Restricted Subsidiary from a financial point of view or that such transaction meets the requirements of Section 4.11(a)(1);

(9) (a) the existence of, or the performance by the Parent or any Restricted Subsidiary of its obligations under the terms of, any equityholders, investor rights or similar agreement (including any registration rights agreement or purchase agreements related thereto) to which it is party as of the Issue Date and (b) the payment of fees, costs and expenses related to registration rights and indemnities provided to equityholders pursuant to equityholders, investor rights, registration rights or similar agreements;

(10) transactions between the Parent or any Restricted Subsidiary of the Parent and any Person, a director of which is also a director of the Parent and such director is the sole cause for such Person to be deemed an Affiliate of the Parent or such Restricted Subsidiary; provided that such director shall abstain from voting as a director of the Parent on any matter involving such other Person;

(11) loans, advances or guarantees provided to or reimbursement of expenses incurred by employees, officers, directors, consultants or independent contracts for bona fide business purposes or in the ordinary course of business and permitted under clause (11) of the definition of Permitted Investments;

(12) (i) guarantees by the Parent or any of its Restricted Subsidiaries of performance of obligations of the Parent's Unrestricted Subsidiaries in the ordinary course of business, except for guarantees of Indebtedness and (ii) pledges by the Parent or any of its Restricted Subsidiaries of (or any guarantee by the Parent or any of its Restricted Subsidiaries limited in recourse solely to) Equity Interests in the Parent's Unrestricted Subsidiaries for the benefit of lenders or other creditors of such Unrestricted Subsidiaries;

(13) pledges and granting of Liens by the Parent or any Restricted Subsidiary of, and Guarantees by the Parent or any Restricted Subsidiary limited in recourse solely to, Capital Stock in Unrestricted Subsidiaries and Joint Ventures solely for the purposes

of securing Non-Recourse Debt, and occurrences of liabilities with respect to Customary Recourse Exceptions;

(14) any Affiliate Transaction with a Person in its capacity as a holder of Indebtedness or Equity Interests of the Parent or any Restricted Subsidiary if such Person is treated no more favorably than the other similarly situated holders of Indebtedness or Equity Interests of the Parent or such Restricted Subsidiary; and

(15) the existence of and transactions effected in accordance with (a) the terms of agreements or arrangements in effect on the Issue Date, (b) any amendment or replacement of any of such agreements or (c) any agreements entered into hereafter that are similar to any of such agreements, so long as, in the case of clauses (b) or (c) of this Section 4.11(b)(15), the terms of any such amendment or replacement agreement or future agreement are, on the whole, either not materially less advantageous to the Parent than the agreement so amended or replaced or the similar agreement referred to in the preceding clause (a) of this Section 4.11(b)(15), respectively, as determined in the good faith judgment of the Parent.

Section 4.12 Liens.

The Parent will not and will not permit any of its Restricted Subsidiaries to, create, incur, assume or otherwise cause or suffer to exist or become effective any Lien of any kind (other than Permitted Liens) securing Indebtedness upon any of their property or assets, now owned or hereafter acquired, unless the Notes or any Guarantee of the Parent or such Restricted Subsidiary, as applicable, is secured on an equal and ratable basis with (or on a senior basis to, in the case of obligations subordinated in right of payment to the Notes or such Guarantee, as the case may be) the obligations so secured until such time as such obligations are no longer secured by such Lien. A Lien created for the benefit of the Holders pursuant to this paragraph shall provide by its terms that such Lien shall be automatically and unconditionally released and discharged upon the release and discharge of the Lien that gave rise to the obligation to secure the Notes.

Section 4.13 [Reserved].

Section 4.14 Parent Existence.

Subject to Article 5 and Section 10.04 hereof, each of the Parent and the Issuer shall do or cause to be done all things necessary to preserve and keep in full force and effect:

(1) their respective corporate or partnership existence, as applicable, and the corporate, partnership or other existence of each other Restricted Subsidiary of the Parent, in accordance with the respective organizational documents (as the same may be amended from time to time) of the Parent, the Issuer or any such other Restricted Subsidiary of the Parent; and

(2) the rights (charter and statutory), licenses and franchises of the Parent and its Restricted Subsidiaries;

provided, however, that the Parent shall not be required to preserve the corporate, partnership or other existence of any of its Restricted Subsidiaries (other than the Issuer) or any such right, license or franchise, if the Parent shall determine that the preservation thereof is no longer desirable in the conduct of the business of the Parent and its Restricted Subsidiaries, taken as a whole, and that the loss thereof is not adverse in any material respect to the Holders of the Notes.

Section 4.15 Offer to Repurchase Upon Change of Control.

(a) Upon the occurrence of a Change of Control Triggering Event the Issuer will make an offer (a “Change of Control Offer”) to each Holder to repurchase all or any part (equal to $2,000 or an integral multiple of $1,000 in excess thereof) of that Holder’s Notes at a purchase price in cash equal to 101% of the aggregate principal amount of Notes repurchased, plus accrued and unpaid interest, if any, on the Notes repurchased to the date of settlement (the “Change of Control Settlement Date”, and such payment, the “Change of Control Payment”), subject to the rights of Holders of record on the relevant record date to receive interest due on the relevant interest payment date that is on or prior to the Change of Control Settlement Date. Within 30 days following any Change of Control Triggering Event, the Issuer will send a notice to each Holder and the Trustee describing the transaction or transactions that constitute the Change of Control and stating:

(1) that the Change of Control Offer is being made pursuant to this Section 4.15 and that all Notes tendered will be accepted for payment;

(2) the purchase price and the expiration date of the Change of Control Offer, which shall be no earlier than 15 days and no later than 60 days from the date such notice is sent (except in the case of a conditional Change of Control Offer made in advance of a Change of Control as described below);

(3) that any Note not tendered will continue to accrue interest;

(4) that, unless the Issuer defaults in the payment of the Change of Control Payment, all Notes accepted for payment pursuant to the Change of Control Offer will cease to accrue interest after the Change of Control Settlement Date;

(5) that Holders electing to have any Notes purchased pursuant to a Change of Control Offer will be required to surrender the Notes, with the form entitled “Option of Holder to Elect Purchase” attached to the Notes completed, or transfer by book-entry transfer, to the Paying Agent at the address specified in the notice prior to the expiration date of the Change of Control Offer;

(6) that Holders will be entitled to withdraw their election if the Paying Agent receives, not later than the close of business on the second Business Day preceding the expiration date of the Change of Control Offer, a telegram, electronic image scan or letter setting forth the name of the Holder, the principal amount of Notes delivered for purchase, and a statement that such Holder is withdrawing its election to have the Notes purchased; and

(7) that Holders whose Notes are being purchased only in part will be issued new Notes equal in principal amount to the unpurchased portion of the Notes surrendered, which unpurchased portion must be equal to $2,000 in principal amount or an integral multiple of $1,000 in excess thereof.

A Change of Control Offer or Alternate Offer may be made at the same time as consents are solicited with respect to an amendment, supplement or waiver of this Indenture, Notes and/or Guarantees (but the Change of Control Offer or Alternate Offer may not condition tenders on the delivery of such consents).

The Issuer will comply with the requirements of Rule 14e-1 under the Exchange Act and any other securities laws and regulations thereunder to the extent those laws and regulations are applicable in connection with the repurchase of the Notes as a result of a Change of Control Triggering Event. To the extent that the provisions of any securities laws or regulations conflict with this Section 4.15, the Issuer will comply with the applicable securities laws and regulations and will not be deemed to have breached its obligations under this Section 4.15 by virtue of such conflict.

(b) Promptly following the expiration of the Change of Control Offer, the Issuer will, to the extent lawful, accept for payment all Notes or portions of Notes properly tendered pursuant to the Change of Control Offer. Promptly after such acceptance, the Issuer will on the Change of Control Settlement Date:

(1) deposit with the Paying Agent an amount equal to the Change of Control Payment in respect of all Notes or portions of Notes properly tendered; and

(2) deliver or cause to be delivered to the Trustee the Notes properly accepted together with an Officer’s Certificate stating the aggregate principal amount of Notes or portions of Notes being purchased by the Issuer.

On the Change of Control Settlement Date, the Paying Agent will promptly pay (but in any case not later than five Business Days after the Change of Control Settlement Date) to each Holder of Notes properly tendered the Change of Control Payment for such Notes (or, if all the Notes are then in global form, it will make such payment through the facilities of DTC), and the Trustee will promptly authenticate and mail (or cause to be transferred by book entry) to each Holder a new Note equal in principal amount to any unpurchased portion of the Notes surrendered, if any; provided, however, that each new Note will be in a principal amount of $2,000 or an integral multiple of $1,000 in excess of $2,000. The Issuer will publicly announce the results of the Change of Control Offer on or as soon as practicable after the Change of Control Settlement Date.

(c) Notwithstanding anything to the contrary in this Section 4.15, the Issuer will not be required to make a Change of Control Offer upon a Change of Control Triggering Event if (1) a third party (including the Parent or a Subsidiary of the Parent) makes the Change of Control Offer in the manner, at the time and otherwise in compliance with the requirements set forth in this Section 4.15 applicable to a Change of Control Offer made by the Issuer and purchases all Notes properly tendered and not withdrawn under the Change of Control Offer,

(2) notice of redemption of all outstanding Notes has been previously or concurrently given pursuant to Section 3.03 hereof, unless and until there is a default in payment of the applicable redemption price, or (3) in connection with or in contemplation of any Change of Control, the Issuer has made an offer to purchase any and all outstanding Notes validly tendered at a cash price equal to or higher than the Change of Control Payment (an “Alternate Offer”) and has purchased all outstanding Notes properly tendered in accordance with the terms of such Alternate Offer.

(d) In the event that Holders of not less than 90.0% of the aggregate principal amount of the then outstanding Notes validly tender and do not validly withdraw such Notes in connection with such Change of Control Offer, Alternate Offer or other tender offer and the Issuer purchases, or any third party making such Change of Control Offer, Alternate Offer or other tender offer in lieu of the Issuer purchases, all of the Notes validly tendered and not validly withdrawn by such Holders, all of the Holders of the Notes will be deemed to have consented to such Change of Control Offer, Alternate Offer or other tender offer and accordingly, the Issuer or such third party will have the right upon not less than 15 days’ nor more than 60 days’ prior notice, given not more than 60 days following such purchase date, to redeem (with respect to the Issuer) or purchase (with respect to a third party) all Notes that remain outstanding following such purchase at a price equal to the highest price offered to each other Holder in such Change of Control Offer, Alternate Offer or other tender offer, plus, to the extent not included in the Change of Control Offer, Alternate Offer or other tender offer payment, accrued and unpaid interest, if any, to, but not including, the applicable redemption date (subject to the right of the Holders of record on the relevant record date to receive interest due on an interest payment date that is on or prior to the applicable redemption date).

(e) Any notice in respect of a Change of Control Offer or Alternate Offer may be sent prior to the occurrence of a Change of Control if a definitive agreement is in place for the Change of Control at the time the Change of Control Offer or Alternate Offer is made, to the extent that such notice states that the Change of Control Offer or Alternate Offer is conditional on the occurrence of such Change of Control and describes each such condition, and, if applicable, stating that, in the Parent’s discretion, the Change of Control Settlement Date may be delayed until such time (including more than 60 days after the notice is mailed or delivered, including by electronic transmission) as any or all such conditions shall be satisfied (or waived by Parent in its sole discretion), or that such purchase may not occur and such notice may be rescinded in the event that the Parent shall determine that any or all such conditions shall not have been satisfied (or waived by Parent in its sole discretion) by the Change of Control Settlement Date, or by the Change of Control Settlement Date as so delayed, or such notice may be rescinded at any time in the Parent’s discretion if in the good faith judgment of the Parent any or all such conditions will not be satisfied.

(f) The Issuer’s obligation to make a Change of Control Offer may be waived, modified or terminated with the consent of the Holders of a majority in principal amount of the Notes then outstanding (including consents obtained in connection with a tender offer or exchange offer for the Notes).

Section 4.16 [Reserved].

Section 4.17 Additional Guarantees.

If, after the Issue Date, any Restricted Subsidiary of the Parent that is not already a Guarantor (excluding the Issuer) guarantees or otherwise becomes a borrower with respect to any Indebtedness under the Credit Agreement, then that Subsidiary will become a Guarantor by executing a supplemental indenture substantially in the form of Exhibit E hereto and delivering it to the Trustee within 20 Business Days of the date on which it guaranteed or otherwise became a borrower of such Indebtedness; provided, however, that the preceding shall not apply to Subsidiaries of the Parent that have properly been designated as Unrestricted Subsidiaries in accordance with Section 4.18 for so long as they continue to constitute Unrestricted Subsidiaries. Notwithstanding the preceding, any Guarantee of a Restricted Subsidiary that was incurred pursuant to this Section 4.17 will be released in the circumstances described under Section 10.05(e).

Section 4.18 Designation of Restricted and Unrestricted Subsidiaries.

The Board of Directors of the Parent may designate any Restricted Subsidiary of the Parent (other than the Issuer) to be an Unrestricted Subsidiary if that designation would not cause a Default or Event of Default. If a Restricted Subsidiary of the Parent is designated as an Unrestricted Subsidiary, the aggregate Fair Market Value of all outstanding Investments owned by the Parent and its Restricted Subsidiaries in the Subsidiary properly designated as an Unrestricted Subsidiary will be deemed to be either an Investment made as of the time of the designation that will reduce the amount available for Restricted Payments under Section 4.07(a) or represent Permitted Investments, as determined by the Parent. Such designation of a Restricted Subsidiary as an Unrestricted Subsidiary will only be permitted if the Investment would be permitted at that time and if the Subsidiary so designated otherwise meets the definition of an Unrestricted Subsidiary.

The Board of Directors of the Parent may at any time designate any Unrestricted Subsidiary to be a Restricted Subsidiary, provided that such designation will be deemed to be an incurrence of Indebtedness by a Restricted Subsidiary of the Parent of any outstanding Indebtedness of such Unrestricted Subsidiary and such designation of an Unrestricted Subsidiary as a Restricted Subsidiary will only be permitted if (1) such Indebtedness is permitted under Section 4.09, calculated on a pro forma basis as if such designation had occurred at the beginning of the Test Period, and Section 4.12 and (2) no Default or Event of Default with respect to Section 4.09 and Section 4.12 or any other covenant in this Indenture would be in existence following such designation.

Any designation of a Subsidiary of the Parent as an Unrestricted Subsidiary will be evidenced to the Trustee by filing with the Trustee a Board Resolution giving effect to such designation and an Officer's Certificate certifying that such designation complied with the preceding conditions and was permitted by Section 4.07. If, at any time, any Unrestricted Subsidiary would fail to meet the preceding requirements as an Unrestricted Subsidiary, it will thereafter cease to be an Unrestricted Subsidiary for purposes of this Indenture, and any Indebtedness of such Subsidiary will be deemed to be incurred by a Restricted Subsidiary of the Parent as of such date and, if such Indebtedness is not permitted to be incurred as of such date under Section 4.09, or if such Subsidiary is not in compliance with any other covenants in this

Indenture applicable to Restricted Subsidiaries of the Parent, a Default will have occurred under this Indenture.

Section 4.19 Covenant Termination.

Notwithstanding any provision of this Indenture or of the Notes to the contrary, if at any time (a) the rating assigned to the Notes by at least two out of the three Rating Agencies is an Investment Grade Rating, (b) no Default has occurred and is continuing under this Indenture and (c) the Issuer has delivered to the Trustee an Officer’s Certificate certifying to the foregoing provisions of this sentence (the occurrence of the events described in Section 4.19(a), (b) and (c) being collectively referred to as a “Covenant Termination Event”), then, beginning on that day, the Parent and its Restricted Subsidiaries will no longer be subject to, and will be permanently released from the obligations under Sections 4.07, 4.08, 4.09, 4.10, 4.11, 4.18 and Section 5.01(a)(4) of this Indenture and no Default or Event of Default shall result from any failure to comply with any of the provisions of such Sections.

The Trustee shall not have any obligation to monitor the ratings of the Notes or independently determine or verify if any Covenant Termination Event has occurred or the date thereof and may rely conclusively on the Officer’s Certificate referenced above with respect to the same. The Trustee shall not have any obligation to notify the Holders of the occurrence or date of any Covenant Termination Event, but may provide a copy of such Officer’s Certificate to any Holder upon request.

Section 4.20 Additional Amounts

(a) All payments made by or on behalf of any Guarantor pursuant to the Guarantees, will be made without withholding or deduction for, or on account of, any Taxes imposed or levied by or on behalf of any taxing authority in any jurisdiction in which any Guarantor is then incorporated, organized, engaged in business or resident for tax purposes, or any political subdivision or governmental authority thereof or therein having power to tax or any jurisdiction from or through which payment is made by any Guarantor (the “Relevant Taxing Jurisdiction”), unless required by law or the interpretation or administration thereof. If a Guarantor is obligated to withhold or deduct any amount on account of such Taxes from any payment made under or with respect to the Notes, such Guarantor, as applicable, will:

(1) make such withholding or deduction;

(2) remit the full amount deducted or withheld to the relevant government authority in accordance with the applicable law;

(3) subject to the limitations below, pay such additional amounts (“Additional Amounts”) as may be necessary so that the net amounts received by each Holder or beneficial owner of Notes, after such withholding or deduction (including any such withholding or deduction on such Additional Amounts) will not be less than the amount such Holder or beneficial owner would have received if such Taxes had not been withheld or deducted;

(4) furnish to the Trustee for the benefit of the Holders and beneficial owners of Notes, within 60 days after the date of the payment or remittance of any Taxes is due pursuant to

100

applicable law, certified copies of an official receipt of the relevant government authorities for all amounts deducted or withheld pursuant to applicable law or other documentation evidencing the payment by such Guarantor, as applicable, of those Taxes; and

(5) at least 15 days prior to each date on which any Additional Amounts are payable (or promptly if the obligation to pay Additional Amounts arises after the 15th day prior to that payment date), deliver to the Trustee an Officer’s Certificate (which shall be conclusive absent manifest error) setting forth the calculation of the Additional Amounts to be paid and such other information as the Trustee may reasonably request to enable the Trustee to pay such Additional Amounts to Holders on the payment date.

Notwithstanding the foregoing, no Additional Amounts will be paid with respect to or in respect of a payment:

(1) for Taxes imposed by reason of any Holder or beneficial owner of the Notes not dealing at arm’s length (within the meaning of the Income Tax Act (Canada)) with the Issuer or such Guarantor at the time of making such payment;

(2) for or on account of Taxes imposed on a payment under or with respect to a Note or Guarantee all or a portion of which is deemed under subsection 214(16) of the Income Tax Act (Canada) to be a dividend;

(3) to the extent that any Taxes giving rise to the Additional Amounts are assessed or imposed by reason of the Holder or beneficial owner being a “specified shareholder” as defined in subsection 18(5) of the Income Tax Act (Canada) of the Parent or not dealing at arm’s length (within the meaning of the Income Tax Act (Canada)) with a “specified shareholder” of the Parent;

(4) to the extent that any Taxes giving rise to the Additional Amounts are assessed or imposed by reason of the Holder or beneficial owner being a “specified entity” as defined in subsection 18.4(1) of the Income Tax Act (Canada) in respect of the Parent;

(5) for or on account of Taxes assessed or imposed by reason of the legal nature of the Holder or beneficial owner disentitling such Holder or beneficial owner to the benefit of an applicable treaty or convention if, and to the extent that, the application of such treaty or convention would have resulted in the reduction or elimination of any Taxes as to which Additional Amounts would otherwise have been payable to a Holder or beneficial owner;

(6) for or on account of Taxes assessed or imposed by reason of the Holder or the beneficial owner of the Notes (or a fiduciary, settlor, beneficiary, partner of, member or shareholder of, or possessor of a power over, the relevant Holder or beneficial owner, if the relevant Holder or beneficial owner is an estate, trust, nominee, partnership, limited liability company or corporation) being a resident, domiciliary or national of, incorporated in, or engaged in business or maintaining a permanent establishment or other physical presence in or otherwise having some present or former connection with the Relevant Taxing Jurisdiction otherwise than by the mere acquisition, holding or disposition of the Notes or the receipt of payments or enforcement rights thereunder;

101

(7) for or on account of any Taxes assessed, imposed or deducted or withheld by reason of the failure of the Holder or beneficial owner of the Note to comply with any certification, identification, documentation or other reporting requirements if compliance is required by law (including any applicable tax treaty), regulation or by reason of the interpretation or administration of such law by the relevant Governmental Authority, and the Holder or beneficial owner is legally eligible to do so, as a pre-condition to exemption from, or reduction in the rate of withholding or deduction of such Taxes;

(8) for or on account of any Tax assessed, imposed or deducted or withheld as a result of the presentation of any Note for payment (where presentation is required) more than 30 days after the relevant payment is first made available for payment to the Holder or beneficial owner (except to the extent that the Holder or beneficial owner would have been entitled to Additional Amounts had the Note been presented on the last day of such 30 day period);

(9) for or on account of any estate, inheritance, gift, sales, value added, transfer, use, capital gains, excise Tax, personal property or similar Tax, assessment or other governmental charge;

(10) for or on account of any Tax, duty, assessment or other governmental charge that is payable otherwise than by withholding or deduction from payments under or with respect to the Notes (other than Taxes payable pursuant to Regulation 803 of the Income Tax Act (Canada), or any similar successor provision or equivalent provision of any provincial or territorial law);

(11) for or on account of any Tax imposed or assessed with respect to any payment on a Note to any Holder who is a fiduciary, partnership or other entity other than the sole beneficial owner of that payment to the extent that such Tax would not have been imposed had the Holder of the Notes been the beneficiary or settler with respect to the fiduciary, a member of that partnership or sole beneficial owner of the payment;

(12) for or on account of any Tax, duty, assessment or other governmental charge imposed pursuant to Sections 1471 through 1474 of the Code as of the Issue Date (and any amended or successor version that is substantively comparable), any current or future regulations or official interpretations thereof, any similar law or regulation adopted pursuant to an intergovernmental agreement between a non-U.S. jurisdiction and the United States with respect to the foregoing or any agreements entered into pursuant to Section 1471(b)(1) of the Code; or

(13) any combination of the exceptions listed in clauses (1) through (12) immediately above.

(b) Any reference in this Indenture to the payment of principal, premium, if any, interest, purchase price, redemption price or any other amount payable under or with respect to any Note, will be deemed to include the payment of Additional Amounts to the extent that, in such context, Additional Amounts are, were or would be payable in respect thereof. The Guarantors' obligation to make payments of Additional Amounts will survive any termination of this Indenture or the defeasance of any rights thereunder, any transfer by a Holder of its Notes (subject to the exclusions described in clauses (1) through (13) of Section 4.20(a)), and will apply, mutatis mutandis, to any jurisdiction in which any successor Person to any Guarantor is

102

organized, incorporated, engaged in business or is otherwise resident or treated as resident for tax purposes, or any jurisdiction from or through which payment is made by or on behalf of such successor Person (including, without limitation, the jurisdiction of the Paying Agent).

(c) The Trustee shall have no duty whatsoever to determine whether any Additional Amounts are payable or the amount thereof.

(3) failure by the Issuer or the Parent to comply with the provisions of Section 4.10, 4.15 or 5.01 hereof;

(6) default under any mortgage, indenture or instrument under which there may be issued or by which there may be secured or evidenced any Indebtedness for money borrowed by the Parent or any of its Restricted Subsidiaries, or the payment of which is guaranteed by the Parent or any of its Restricted Subsidiaries (other than the Indebtedness owed to the Parent or a Restricted Subsidiary), whether such Indebtedness or guarantee now exists, or is created after the Issue Date, if that default:

(A) is caused by a failure to pay principal of, premium on, if any, or interest on, if any, such Indebtedness prior to the expiration of the grace period provided in such Indebtedness on the date of such default (a “Payment Default”); or

(B) results in the acceleration of such Indebtedness prior to its Stated Maturity,

and, in each case, the principal amount of any such Indebtedness, together with the principal amount of any other such Indebtedness under which there has been a Payment Default or the maturity of which has been so accelerated, exceeds in the aggregate $75.0 million; provided, however, if, prior to any acceleration of the Notes, (i) any such Payment Default is cured or waived, (ii) any such acceleration is rescinded, or (iii) such Indebtedness is repaid during the 60 Business Day period commencing upon the end of any applicable grace period for such Payment Default or the occurrence of such acceleration, as the case may be, any Default or Event of Default (but not any acceleration of the Notes) caused by such Payment Default or acceleration shall be automatically rescinded, so long as such rescission does not conflict with any judgment, decree or applicable law;

(7) failure by the Parent or any of its Restricted Subsidiaries to pay final non-appealable judgments entered by a court or courts of competent jurisdiction aggregating in excess of $75.0 million (to the extent not covered by insurance by a reputable and creditworthy insurer as to which the insurer has not disclaimed coverage), which judgments are not paid, satisfied, annulled, rescinded, discharged or stayed, for a period of 60 days after they become final and non-appealable;

(8) the Issuer or any of the Parent’s Restricted Subsidiaries that is a Significant Subsidiary or any group of Restricted Subsidiaries of the Parent that, taken together, would constitute a Significant Subsidiary pursuant to or within the meaning of Bankruptcy Law:

(B) consents to the entry of an order for relief against it in an involuntary case,

(D) makes a general assignment for the benefit of its creditors, or

(E) generally is not paying its debts as they become due;

(9) a court of competent jurisdiction enters an order or decree under any Bankruptcy Law that:

106

(A) is for relief against the Issuer or any of the Parent’s Restricted Subsidiaries that is a Significant Subsidiary or any group of Restricted Subsidiaries of the Parent that, taken together, would constitute a Significant Subsidiary in an involuntary case;

(B) appoints a custodian of the Parent, the Issuer or any of the Parent’s Restricted Subsidiaries that is a Significant Subsidiary or any group of Restricted Subsidiaries of the Parent that, taken together, would constitute a Significant Subsidiary or for all or substantially all of the property of the Parent or any of its Restricted Subsidiaries that is a Significant Subsidiary or any group of Restricted Subsidiaries of the Parent that, taken together, would constitute a Significant Subsidiary; or

(C) orders the liquidation of the Issuer or any of the Parent’s Restricted Subsidiaries that is a Significant Subsidiary or any group of Restricted Subsidiaries of the Parent that, taken together, would constitute a Significant Subsidiary;

and the order or decree remains unstayed and in effect for 60 consecutive days; or

(10) except as permitted by this Indenture, any Guarantee of any Guarantor that is a Significant Subsidiary of the Parent is held in any final non-appealable judgment by a court of competent jurisdiction to be unenforceable or invalid or ceases for any reason to be in full force and effect, or any Guarantor that is a Significant Subsidiary of the Parent, or any Person acting on behalf of such Guarantor, denies or disaffirms its obligations under its Guarantee.

Notwithstanding the foregoing, a Default under Section 6.01(6) or 6.01(7) will not constitute an Event of Default until the Trustee or the Holders of at least 30% in principal amount of the outstanding Notes (with a copy to the Trustee) notify the Parent of the Default and, with respect to Section 6.01(7), the Issuer does not cure such Default within the time specified in Section 6.01(7) after receipt of such notice. Any notice of Default may not be given with respect to any action taken, and reported publicly or to Holders, more than two years prior to such notice of Default.

Any notice of Default may not be given with respect to any action taken, and reported publicly or to Holders, more than two years prior to such notice of Default. Any notice of Default, notice of acceleration or instruction to the Trustee to provide a notice of Default, notice of acceleration or take any other action (a “Noteholder Direction”) provided by any one or more Holders (each, a “Directing Holder”) must be accompanied by a signed Position Representation and Verification Form (in the form attached to this Indenture) delivered to the Parent and the Trustee (a “Position Representation and Verification Form”). The Position Representation and Verification Form will contain a representation that the applicable Directing Holder is not (or, in the case such Holder is DTC or its nominee, that such Holder is being instructed solely by Beneficial Owners that have represented to such Holder that they are not) Net Short (a “Position Representation”), which representation, in the case of a Noteholder Direction relating to the delivery of a notice of Default shall be deemed a continuing representation until the resulting

107

Event of Default is cured or otherwise ceases to exist or the Notes are accelerated. The Position Representation and Verification Form will also contain a covenant by the applicable Directing Holder to provide the Parent with such other information as the Parent may reasonably request from time to time in order to verify the accuracy of such Holder’s Position Representation within five Business Days of request therefor (a “Verification Covenant”). The Trustee shall have no duty whatsoever to obtain for, or provide such other information to, the Parent. In any case in which the Holder is DTC or its nominee, any Position Representation and Verification Form required hereunder shall be provided by the Beneficial Owners of the Notes in lieu of DTC or its nominee and DTC shall be entitled to conclusively rely on such Position Representation and Verification Form in delivering its notice or instruction to the Trustee.

If, following the delivery of a Noteholder Direction, but prior to acceleration of the Notes, the Parent determines in good faith that there is a reasonable basis to believe a Directing Holder was, at any relevant time, in breach of its Position Representation and provides to the Trustee an Officer’s Certificate stating that the Parent has initiated litigation in a court of competent jurisdiction seeking a determination that such Directing Holder was, at such time, in breach of its Position Representation, and seeking to invalidate any Default, Event of Default or acceleration (or notice thereof) that resulted from the applicable Noteholder Direction, the cure period with respect to such Default or Event of Default shall be automatically stayed and the cure period with respect to such Default or Event of Default shall be automatically reinstituted and any remedy stayed pending a final and non-appealable determination of a court of competent jurisdiction on such matter. If, following the delivery of a Noteholder Direction, but prior to acceleration of the Notes, the Parent provides to the Trustee an Officer’s Certificate stating that a Directing Holder failed to satisfy its Verification Covenant, the cure period with respect to such Default or Event of Default shall be automatically stayed and the cure period with respect to any such Default or Event of Default that resulted from the applicable Noteholder Direction shall be automatically reinstituted and any remedy stayed pending satisfaction of such Verification Covenant. Any breach of the Position Representation (as confirmed by a court determination) shall result in such Holder’s participation in such Noteholder Direction being disregarded; and, if, without the participation of such Holder, the percentage of Notes held by the remaining Holders that provided such Noteholder Direction would have been insufficient to validly provide such Noteholder Direction, such Noteholder Direction shall be void ab initio, with the effect that such Default or Event of Default shall be deemed never to have occurred, acceleration voided and the Trustee shall be deemed not to have received such Noteholder Direction or any notice of such Default or Event of Default; provided, however, such voiding of such Noteholder Direction shall not void or invalidate any indemnity or security provided by the Directing Holders to the Trustee, which such indemnification or security obligations shall continue to survive.

Notwithstanding anything in the preceding two paragraphs to the contrary, any Noteholder Direction delivered to the Trustee during the pendency of an Event of Default as the result of a bankruptcy, insolvency, receivership, reorganization or similar proceeding shall not require compliance with the foregoing paragraphs.

For the avoidance of doubt, the Trustee shall be entitled to conclusively rely on any Noteholder Direction delivered to it in accordance with this section, shall have no duty to inquire as to or investigate the accuracy of any Position Representation, enforce compliance with any Verification Covenant, verify any statements in any Officer’s Certificate delivered to it, or

108

otherwise make calculations, investigations or determinations with respect to Derivative Instruments, Net Shorts, Long Derivative Instruments, Short Derivative Instruments or otherwise. The Trustee shall have no liability to the Parent, any Holder or any other Person in acting in good faith on a Noteholder Direction or on any Officer’s Certificate with respect to a Noteholder Direction or Verification Covenant, and the Parent, any Holder or any such other Person waives any and all claims, in law and/or in equity, against the Trustee and agrees not to commence any legal proceeding against the Trustee in respect of, and agrees that the Trustee will not be liable for any action that the Trustee takes with respect to, a Noteholder Direction or any Officer’s Certificate with respect to a Noteholder Direction or Verification Covenant or in accordance with the foregoing paragraphs.

With its acquisition of the Notes, each Holder and subsequent purchaser of the Notes consents to the delivery of its Position Representation by the Trustee to the Parent in accordance with this Section 6.01. Each Holder and subsequent purchaser of the Notes waives any and all claims, in law and/or in equity, against the Trustee and agrees not to commence any legal proceeding against the Trustee in respect of, and agrees that the Trustee will not be liable for any action that the Trustee takes in accordance with this Section 6.01, or arising out of or in connection with following instructions or taking actions in accordance with a Noteholder Direction. The Parent and the Issuer hereby waive any and all claims, in law and/or in equity, against the Trustee, and agree not to commence any legal proceeding against the Trustee in respect of, and agree that the Trustee will not be liable for any action that the Trustee takes in accordance with this Section 6.01, or arising out of or in connection with following instructions or taking actions in accordance with a Noteholder Direction. The Parent and the Issuer hereby confirm that any and all other actions that the Trustee takes or omits to take under this Section 6.01 and all fees, costs and expenses of the Trustee and its agents and counsel arising hereunder and in connection herewith shall be covered by the Issuer’s indemnification under Section 7.07. The Trustee will treat all Holders equally with respect to their rights under this Section 6.01, and in connection with the requisite percentages required under this Section 6.01, and the Trustee will also treat all outstanding Notes equally irrespective of any Position Representation in determining whether the requisite percentage has been obtained with respect to the initial delivery of the Noteholder Direction.

Section 6.02 Acceleration.

In the case of an Event of Default specified in clause (8) or (9) of Section 6.01 hereof, with respect to the Issuer, all outstanding Notes will become due and payable immediately without further action or notice. If any other Event of Default occurs and is continuing, the Trustee or the Holders of at least 30% in principal amount of the then total outstanding Notes by written notice to the Issuer and the Trustee may declare the principal, premium, if any, interest and any other monetary obligations (including with respect to any Additional Amounts) on all the then outstanding Notes to be due and payable immediately.

Upon the effectiveness of such declaration, such principal of and premium, if any, and interest (including with respect to any Additional Amounts) will be due and payable immediately.

109

The Holders of a majority in aggregate principal amount of the then outstanding Notes by written notice to the Issuer and the Trustee may, on behalf of all of the Holders of all the Notes, rescind an acceleration and its consequences hereunder, if the rescission would not conflict with any judgment or decree and if all existing Events of Default (except nonpayment of principal of, premium on, if any, or interest on the Notes that has become due solely because of the acceleration) have been cured or waived.

Section 6.03 Other Remedies.

If an Event of Default occurs and is continuing, the Trustee may pursue any available remedy to collect the payment of principal of, premium on, if any, or interest on the Notes or to enforce the performance of any provision of the Notes or this Indenture.

The Trustee may maintain a proceeding even if it does not possess any of the Notes or does not produce any of them in the proceeding. A delay or omission by the Trustee or any Holder of a Note in exercising any right or remedy accruing upon an Event of Default shall not impair the right or remedy or constitute a waiver of or acquiescence in the Event of Default. All remedies are cumulative to the extent permitted by law.

Section 6.04 Waiver of Past Defaults.

The Holders of a majority in aggregate principal amount of the then outstanding Notes may, by notice to the Trustee, on behalf of the Holders of all of the Notes, waive any existing Default or Event of Default and its consequences hereunder, except a continuing Default or Event of Default in the payment of principal of, premium on, if any, or interest, if any, on the Notes (including in connection with an offer to purchase any Notes). Upon notice to the Trustee of any such waiver, such Default shall cease to exist, and any Event of Default arising therefrom shall be deemed to have been cured for every purpose of this Indenture; but no such waiver shall extend to any subsequent or other Default or impair any right consequent thereon.

Section 6.05 Control by Majority.

Holders of a majority in aggregate principal amount of the then outstanding Notes may direct the time, method and place of conducting any proceeding for exercising any remedy available to the Trustee or exercising any trust or power conferred on it. However, the Trustee may refuse to follow any direction that conflicts with law or this Indenture that the Trustee determines may be unduly prejudicial to the rights of other Holders of Notes (it being understood that the Trustee does not have an affirmative duty to determine whether or not any such direction is unduly prejudicial to the rights of Holders of the Notes not joining in giving such direction) or that may involve the Trustee in personal liability; provided, however, that the Trustee may take any other action deemed proper by the Trustee that is not inconsistent with such direction.

Section 6.06 Limitation on Suits.

No Holder of a Note may pursue any remedy with respect to this Indenture or the Notes unless:

(1) such Holder has previously given to the Trustee written notice that an Event of Default is continuing;

(2) Holders of at least 25% in aggregate principal amount of the then outstanding Notes make a written request to the Trustee to pursue the remedy;

(3) such Holder or Holders offer and, if requested, provide to the Trustee security or indemnity satisfactory to the Trustee against any loss, liability or expense;

(4) the Trustee does not comply with such request within 60 days after receipt of the request and the offer of security or indemnity; and

(5) during such 60-day period, Holders of a majority in aggregate principal amount of the then outstanding Notes do not give the Trustee a direction inconsistent with such request.

A Holder of a Note may not use this Indenture to prejudice the rights of another Holder of a Note or to obtain a preference or priority over another Holder of a Note. The Trustee will have no duty to determine whether any Holder’s use of this Indenture complies with the preceding sentence.

Section 6.07 Rights of Holders of Notes to Receive Payment.

Notwithstanding any other provision of this Indenture, the right of any Holder of a Note to receive payment of principal of, premium on, if any, or interest, if any, on the Note, on or after the respective due dates expressed in the Note (including in connection with an offer to purchase), or to bring suit for the enforcement of any such payment on or after such respective dates, shall not be impaired or affected without the consent of such Holder.

Section 6.08 Collection Suit by Trustee.

If an Event of Default specified in Section 6.01(1) or (2) hereof occurs and is continuing, the Trustee is authorized to recover judgment in its own name and as trustee of an express trust against the Issuer for the whole amount of principal of, premium on, if any, and interest, if any, remaining unpaid on, the Notes and, to the extent lawful, interest on overdue principal and interest and such further amount as shall be sufficient to cover the costs and expenses of collection, including the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel.

Section 6.09 Trustee May File Proofs of Claim.

The Trustee is authorized to file such proofs of claim and other papers or documents as may be necessary or advisable in order to have the claims of the Trustee (including any claim for the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel) and the Holders of the Notes allowed in any judicial proceedings relative to the Issuer (or any other obligor upon the Notes), its creditors or its property and shall be entitled and empowered to collect, receive and distribute any money or other property payable or deliverable on any such claims and any custodian in any such judicial proceeding is hereby authorized by

111

each Holder to make such payments to the Trustee, and in the event that the Trustee shall consent to the making of such payments directly to the Holders, to pay to the Trustee any amount due to it for the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel, and any other amounts due the Trustee under Section 7.07 hereof. To the extent that the payment of any such compensation, expenses, disbursements and advances of the Trustee, its agents and counsel, and any other amounts due the Trustee under Section 7.07 hereof out of the estate in any such proceeding, shall be denied for any reason, payment of the same shall be secured by a Lien on, and shall be paid out of, any and all distributions, dividends, money, securities and other properties that the Holders may be entitled to receive in such proceeding whether in liquidation or under any plan of reorganization or arrangement or otherwise. Nothing herein contained shall be deemed to authorize the Trustee to authorize or consent to or accept or adopt on behalf of any Holder any plan of reorganization, arrangement, adjustment or composition affecting the Notes or the rights of any Holder, or to authorize the Trustee to vote in respect of the claim of any Holder in any such proceeding.

Section 6.10 Priorities.

If the Trustee collects any money pursuant to this Article 6, it shall pay out the money in the following order:

First: to the Trustee, its agents and attorneys for amounts due under Section 7.07 hereof, including payment of all compensation, expenses and liabilities incurred, and all advances made, by the Trustee and the costs and expenses of collection;

Second: to Holders of Notes for amounts due and unpaid on the Notes for principal, premium, if any, and interest, if any, ratably, without preference or priority of any kind, according to the amounts due and payable on the Notes for principal, premium, if any, and interest, if any, respectively; and

Third: to the Issuer or to such party as a court of competent jurisdiction shall direct.

The Trustee may fix a record date and payment date for any payment to Holders of Notes pursuant to this Section 6.10.

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 the Trustee for any action taken or omitted by it as a Trustee, a court in its discretion may require the filing by any party litigant in 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, 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 Trustee, a suit by a Holder of a Note pursuant to Section 6.07 hereof, or a suit by Holders of more than 10% in aggregate principal amount of the then outstanding Notes.

Section 7.01 Duties of Trustee.

(j) The Trustee may request that the Issuer deliver an Officer’s Certificate setting forth the names of individuals and/or titles of officers authorized at such time to take specified actions pursuant to this Indenture, which Officer’s Certificate may be signed by any person authorized to sign an Officer’s Certificate, including any person specified as so authorized in any such certificate previously delivered and not superseded.

Section 7.03 Individual Rights of Trustee.

The Trustee in its individual or any other capacity may become the owner or pledgee of Notes and may otherwise deal with the Issuer or any Affiliate of the Issuer with the same rights it would have if it were not Trustee. However, in the event that the Trustee acquires any conflicting interest (as defined in the TIA after a Default has occurred and is continuing) it must eliminate such conflict within 90 days or resign. Any Agent may do the same with like rights and duties. The Trustee is also subject to Sections 7.10 and 7.11 thereof.

Except in the case of a Default or Event of Default in payment of principal of, premium on, if any, or interest on, any Note, the Trustee may withhold the notice if and so long as a committee of its Responsible Officers in good faith determines that withholding the notice is in the interests of the Holders of the Notes.

Section 7.06 [Reserved].

Section 7.07 Compensation and Indemnity.

(a) The Issuer will pay to the Trustee from time to time reasonable compensation for its acceptance of this Indenture and services hereunder. The Trustee's compensation will not be limited by any law on compensation of a trustee of an express trust. The Issuer will reimburse the Trustee promptly upon request for all reasonable disbursements, advances and expenses incurred or made by it in addition to the compensation for its services. Such expenses will include the reasonable compensation, disbursements and expenses of the Trustee's agents and counsel.

(b) The Issuer and the Guarantors, jointly and severally, will indemnify, defend and protect each of the Trustee and its officers, directors, agents and employees for, and hold them harmless against, any and all losses, liabilities, damages, claims or expenses, including taxes (other than taxes based upon, measured by or determined by the earnings or income of the Trustee) and court costs, incurred by it arising out of or in connection with the acceptance or administration of its duties under this Indenture, including the costs and expenses of enforcing this Indenture against the Issuer and the Guarantors (including this Section 7.07) and defending itself against any claim (whether asserted by the Issuer, the Guarantors, any Holder or any other Person) or liability in connection with the exercise or performance of any of its powers or duties hereunder, except to the extent any such loss, liability or expense may be attributable to its willful misconduct or gross negligence as determined by a final, non-appealable judgment of a court of competent jurisdiction. The Trustee will notify the Issuer promptly of any claim for which it may seek indemnity. Failure by the Trustee to so notify the Issuer will not relieve the Issuer or any of the Guarantors of their obligations hereunder. The Issuer or any such Guarantor will defend the claim (to the extent such the Issuer or any such Guarantor does not have a conflict with the defenses available to the Trustee, as determined by the Trustee) and the Trustee will reasonably cooperate in the defense. The Trustee may have separate counsel, and the Issuer will pay the reasonable fees and expenses of such counsel. Neither the Issuer nor any Guarantor need pay for any settlement made without its consent, which consent will not be unreasonably withheld.

116

(c) The obligations of the Issuer and the Guarantors under this Section 7.07 will survive resignation or removal of the Trustee and the satisfaction and discharge of this Indenture.

(d) To secure the Issuer’s and the Guarantors’ payment obligations in this Section 7.07, the Trustee will have a Lien prior to the Notes on all money or property held or collected by the Trustee, except that held in trust to pay principal of, premium on, if any, or interest, if any, on, particular Notes. Such Lien will survive the satisfaction and discharge of this Indenture.

(e) When the Trustee incurs expenses or renders services after an Event of Default specified in Section 6.01(8) or (9) hereof occurs, the expenses and the compensation for the services (including the fees and expenses of its agents and counsel) are intended to constitute expenses of administration under any Bankruptcy Law.

Section 7.08 Replacement of Trustee.

(a) A resignation or removal of the Trustee and appointment of a successor Trustee will become effective only upon the successor Trustee’s acceptance of appointment as provided in this Section 7.08.

(b) The Trustee may resign in writing at any time and be discharged from the trust hereby created by so notifying the Issuer. The Holders of a majority in aggregate principal amount of the then outstanding Notes may remove the Trustee by so notifying the Trustee and the Issuer in writing at least 30 days in advance of such removal. The Issuer may remove the Trustee if:

(1) the Trustee fails to comply with Section 7.10 hereof;

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

(3) a custodian or public officer takes charge of the Trustee or its property; or

(4) the Trustee becomes incapable of acting.

(c) If the Trustee resigns or is removed or if a vacancy exists in the office of Trustee for any reason, the Issuer will 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 appoint a successor Trustee to replace the successor Trustee appointed by the Issuer.

(d) If a successor Trustee does not take office within 60 days after the retiring Trustee resigns or is removed, the retiring Trustee (at the Issuer’s expense), the Issuer, or the Holders of at least 10% in aggregate principal amount of the then outstanding Notes may petition any court of competent jurisdiction for the appointment of a successor Trustee.

117

(e) If the Trustee, after written request by any Holder who has been a Holder for at least six months, fails to comply with Section 7.10 hereof, such Holder may petition any court of competent jurisdiction for the removal of the Trustee and the appointment of a successor Trustee.

(f) A successor Trustee will deliver a written acceptance of its appointment to the retiring Trustee and to the Issuer. Thereupon, the resignation or removal of the retiring Trustee will become effective, and the successor Trustee will have all the rights, powers and duties of the Trustee under this Indenture. The successor Trustee will send a notice of its succession to Holders. The retiring Trustee will promptly transfer all property held by it as Trustee to the successor Trustee; provided all sums owing to the Trustee hereunder have been paid and subject to the Lien provided for in Section 7.07 hereof. Notwithstanding replacement of the Trustee pursuant to this Section 7.08, the Issuer's obligations under Section 7.07 hereof will continue for the benefit of the retiring Trustee.

Section 7.09 Successor Trustee by Merger, etc.

If the Trustee consolidates, merges or converts into, or transfers all or substantially all of its corporate trust business to, another Person, the successor Person without any further act will be the successor Trustee.

Section 7.10 Eligibility; Disqualification.

The Trustee is subject to TIA §311(a), excluding any creditor relationship listed in TIA §311(b). A Trustee who has resigned or been removed shall be subject to TIA §311(a) to the extent indicated therein.

ARTICLE VIII

LEGAL DEFEASANCE AND COVENANT DEFEASANCE

Section 8.01 Option to Effect Legal Defeasance or Covenant Defeasance.

At the option of the Board of Directors of the Parent evidenced by a resolution set forth in an Officer's Certificate, elect to have either Section 8.02 or 8.03 hereof be applied to all outstanding Notes upon compliance with the conditions set forth below in this Article 8.

Section 8.02 Legal Defeasance and Discharge.

Upon the Issuer's exercise under Section 8.01 hereof of the option applicable to this Section 8.02, the Issuer and each of the Guarantors will, subject to the satisfaction of the

118

conditions set forth in Section 8.04 hereof, be deemed to have been discharged from their obligations with respect to all outstanding Notes (including the Guarantees) on the date the conditions set forth below are satisfied (hereinafter, “Legal Defeasance”). For this purpose, Legal Defeasance means that the Issuer and the Guarantors will be deemed to have paid and discharged the entire Indebtedness represented by the outstanding Notes (including the Guarantees), which will thereafter be deemed to be “outstanding” only for the purposes of Section 8.05 hereof and the other Sections of this Indenture referred to in Section 8.02(1) and (2), and to have satisfied all their other obligations under such Notes, the Guarantees and this Indenture (and the Trustee, on demand of and at the expense of the Issuer, shall execute proper instruments acknowledging the same), except for the following provisions which will survive until otherwise terminated or discharged hereunder:

(1) the rights of Holders of outstanding Notes to receive payments in respect of the principal of, premium on, if any, or interest on, such Notes when such payments are due from the trust referred to in Section 8.04 hereof;

(2) the Issuer’s obligations with respect to such Notes under Article 2 and Section 4.02 hereof;

(3) the rights, powers, trusts, duties and immunities of the Trustee hereunder and the Issuer’s and the Guarantors’ obligations in connection therewith; and

(4) this Article 8.

Subject to compliance with this Article 8, the Issuer may exercise its option under this Section 8.02 notwithstanding the prior exercise of their option under Section 8.03 hereof.

Section 8.03 Covenant Defeasance.

Upon the Issuer’s exercise under Section 8.01 hereof of the option applicable to this Section 8.03, the Issuer and each of the Guarantors will, subject to the satisfaction of the conditions set forth in Section 8.04 hereof, be released from each of their respective obligations under the covenants contained in Sections 4.03, 4.07, 4.08, 4.09, 4.10, 4.11, 4.12, 4.15, 4.17 and 4.18 hereof and Section 5.01(a)(4) hereof with respect to the outstanding Notes on and after the date the conditions set forth in Section 8.04 hereof are satisfied (hereinafter, “Covenant Defeasance”), and the Notes will thereafter be deemed not “outstanding” for the purposes of any direction, waiver, consent or declaration or act of Holders (and the consequences of any thereof) in connection with such covenants, but will continue to be deemed “outstanding” for all other purposes hereunder (it being understood that such Notes will not be deemed outstanding for accounting purposes to the extent permitted by IFRS). For this purpose, Covenant Defeasance means that, with respect to the outstanding Notes and Guarantees, the Issuer and the Guarantors may omit to comply with and will have no liability in respect of any term, condition or limitation set forth in any such covenant, whether directly or indirectly, by reason of any reference elsewhere herein to any such covenant or by reason of any reference in any such covenant to any other provision herein or in any other document and such omission to comply will not constitute a Default or an Event of Default under Section 6.01 hereof, but, except as specified above, the remainder of this Indenture and such Notes and Guarantees will be unaffected thereby. In

119

addition, upon the Issuer’s exercise under Section 8.01 hereof of the option applicable to this Section 8.03, subject to the satisfaction of the conditions set forth in Section 8.04 hereof, Sections 6.01(3), (4), (5), (6), (7) and (10) hereof will not constitute Events of Default.

(2) in the case of an election under Section 8.02 hereof, the Issuer must deliver to the Trustee an Opinion of Counsel reasonably acceptable to the Trustee confirming that:

(A) the Issuer has received from, or there has been published by, the Internal Revenue Service a ruling; or

(B) since the Issue Date, there has been a change in the applicable U.S. federal income tax law,

in either case to the effect that, and based thereon such Opinion of Counsel will confirm that, the Holders of the outstanding Notes will not recognize income, gain or loss for U.S. federal income tax purposes as a result of such Legal Defeasance and will be subject to U.S. federal income tax on the same amounts, in the same manner and at the same times as would have been the case if such Legal Defeasance had not occurred;

(3) in the case of an election under Section 8.03 hereof, the Issuer must deliver to the Trustee an Opinion of Counsel reasonably acceptable to the Trustee confirming that the Holders of the outstanding Notes will not recognize income, gain or loss for U.S. federal income tax purposes as a result of such Covenant Defeasance and will be subject to U.S. federal income tax on the same amounts, in the same manner and

at the same times as would have been the case if such Covenant Defeasance had not occurred;

(4) no Default or Event of Default has occurred and is continuing on the date of the deposit made pursuant to Section 8.04(1) (other than a Default or Event of Default resulting from the incurrence of Indebtedness, the proceeds of which are applied to such deposit (and any similar concurrent deposit relating to other Indebtedness), or the incurrence of Liens to secure such Indebtedness);

(5) such Legal Defeasance or Covenant Defeasance will not result in a breach or violation of, or constitute a default under, any material agreement or instrument (other than this Indenture and the agreements governing any other Indebtedness being defeased, discharged or replaced) to which the Parent or any of its Subsidiaries is a party or by which the Parent or any of its Subsidiaries is bound;

(6) the Issuer must deliver to the Trustee an Officer’s Certificate stating that the deposit was not made by the Issuer with the intent of preferring the Holders of Notes over the other creditors of the Issuer or with the intent of defeating, hindering, delaying or defrauding creditors of the Issuer or others; and

(7) the Issuer must deliver to the Trustee an Officer’s Certificate and an Opinion of Counsel (which may be subject to customary assumptions and exclusions), each stating that all conditions precedent relating to the Legal Defeasance or the Covenant Defeasance have been complied with.

Subject to Section 8.06 hereof, all money and non-callable Government Securities (including the proceeds thereof) deposited with the Trustee (or other qualifying trustee, collectively for purposes of this Section 8.05, the "Trustee") pursuant to Section 8.04 hereof in respect of the outstanding Notes will be held in trust and applied by the Trustee, in accordance with the provisions of such Notes and this Indenture, to the payment, either directly or through any Paying Agent (including the Parent or any of its Subsidiaries acting as Paying Agent) as the Trustee may determine, to the Holders of such Notes of all sums due and to become due thereon in respect of principal, premium, if any, and interest, but such money need not be segregated from other funds except to the extent required by law.

The Issuer will pay and indemnify the Trustee against any tax, fee or other charge imposed on or assessed against the cash or non-callable Government Securities deposited pursuant to Section 8.04 hereof or the principal and interest received in respect thereof other than any such tax, fee or other charge which by law is for the account of the Holders of the outstanding Notes.

Notwithstanding anything in this Article 8 to the contrary, the Trustee will deliver or pay to the Issuer from time to time upon the request of the Issuer any money or non-callable Government Securities held by it as provided in Section 8.04 hereof which, in the opinion of a nationally recognized firm of independent public accountants expressed in a written certification

121

thereof delivered to the Trustee (which may be the opinion delivered under Section 8.04(1) hereof), are in excess of the amount thereof that would then be required to be deposited to effect an equivalent Legal Defeasance or Covenant Defeasance.

Section 8.06 Repayment to Issuer.

Subject to applicable escheat and abandoned property laws, any money deposited with the Trustee or any Paying Agent, or then held by the Issuer, in trust for the payment of the principal of, premium on, if any, or interest, if any, on, any Note and remaining unclaimed for two years after such principal, premium, if any, or interest has become due and payable shall be paid to the Issuer on their request or (if then held by the Issuer) will be discharged from such trust; and the Holder of such Note will thereafter be permitted to look only to the Issuer for payment thereof, and all liability of the Trustee or such Paying Agent with respect to such trust money, and all liability of the Issuer as trustee thereof, will thereupon cease; provided, however, that, if any Definitive Notes are then outstanding, the Trustee or such Paying Agent, before being required to make any such repayment, may at the expense of the Issuer cause to be published once, in the New York Times and The Wall Street Journal (national edition), notice that such money remains unclaimed and that, after a date specified therein, which will not be less than 30 days from the date of such notification or publication, any unclaimed balance of such money then remaining will be repaid to the Issuer.

Section 8.07 Reinstatement.

If the Trustee or Paying Agent is unable to apply any U.S. dollars or non-callable Government Securities in accordance with Section 8.02 or 8.03 thereof, as the case may be, by reason of any order or judgment of any court or governmental authority enjoining, restraining or otherwise prohibiting such application, then the Issuer's and the Guarantors' obligations under this Indenture and the Notes and the Guarantees will be revived and reinstated as though no deposit had occurred pursuant to Section 8.02 or 8.03 thereof until such time as the Trustee or Paying Agent is permitted to apply all such money in accordance with Section 8.02 or 8.03 thereof, as the case may be; provided, however, that, if the Issuer makes any payment of principal of, premium on, if any, or interest on any Note following the reinstatement of its obligations, the Issuer will be subrogated to the rights of the Holders of such Notes to receive such payment from the money held by the Trustee or Paying Agent.

123

contained, but the Trustee will not be obligated to enter into such amended or supplemental indenture that affects its own rights, duties or immunities under this Indenture or otherwise.

Section 9.02 With Consent of Holders of Notes.

Except as provided below in this Section 9.02, the Issuer, the Guarantors and the Trustee may amend or supplement this Indenture (including, without limitation, Sections 3.09, 4.10 and 4.15 hereof) and the Notes and the Guarantees with the consent of the Holders of a majority in aggregate principal amount of the then outstanding Notes (including, without limitation, Additional Notes, if any) voting as a single class (including, without limitation, consents obtained in connection with a tender offer or exchange offer for, or purchase of, the Notes or an issuance of Additional Notes), and, subject to Sections 6.04 and 6.07 hereof, any existing Default or Event of Default (other than a Default or Event of Default in the payment of the principal of, premium on, if any, or interest on, the Notes, except a payment default resulting from an acceleration that has been rescinded) or compliance with any provision of this Indenture or the Notes or the Guarantees may be waived with the consent of the Holders of a majority in aggregate principal amount of the then outstanding Notes (including, without limitation, Additional Notes, if any) voting as a single class (including, without limitation, consents obtained in connection with a tender offer or exchange offer for, or purchase of, the Notes or an issuance of Additional Notes). (Section 2.08 hereof shall determine which Notes are considered to be "outstanding" for purposes of this Section 9.02.) However, without the consent of each Holder affected, an amendment, supplement or waiver under this Section 9.02 may not (with respect to any Notes held by a non-consenting Holder):

(1) reduce the principal amount of Notes whose Holders must consent to an amendment, supplement or waiver;

(2) reduce the principal of or change the fixed maturity of any Note or alter the provisions with respect to the redemption or repurchase of the Notes (other than provisions under Sections 4.10 and 4.15);

(3) reduce the rate of or change the time for payment of interest on any Note;

(4) waive a Default or Event of Default in the payment of principal of, or interest, premium or Additional Amount, if any, on the Notes (except a rescission of acceleration of the Notes by the Holders of a majority in aggregate principal amount of the Notes and a waiver of the payment default that resulted from such acceleration);

(5) make any Note payable in currency other than that stated in the Notes;

(6) make any change in the provisions of this Indenture relating to waivers of past Defaults or the rights of Holders of Notes to receive payments of principal of, or interest or premium, if any, on the Notes (other than as permitted in Section 9.02(7) below);

(7) waive a redemption or repurchase payment with respect to any Note (other than a payment required by Section 4.10 or 4.15);

124

(8) release any Guarantor from any of its obligations under its Guarantee or this Indenture, except in accordance with the terms of this Indenture; or
(9) make any change in the preceding amendment, supplement and waiver provisions.

Upon the request of the Issuer accompanied by a resolution of its Board of Directors authorizing the execution of any such amended or supplemental indenture, and upon the filing with the Trustee of evidence satisfactory to the Trustee of the consent of the Holders of Notes as aforesaid, and upon receipt by the Trustee of the documents described in Section 9.06 hereof, the Trustee will join with the Issuer and the Guarantors in the execution of such amended or supplemental indenture unless such amended or supplemental indenture directly affects the Trustee's own rights, duties or immunities under this Indenture or otherwise, in which case the Trustee may in its discretion, but will not be obligated to, enter into such amended or supplemental indenture.

It is not necessary for the consent of the Holders of Notes under this Section 9.02 to approve the particular form of any proposed amendment, supplement or waiver, but it is sufficient if such consent approves the substance thereof.

After an amendment, supplement or waiver under this Section 9.02 becomes effective, the Issuer will send to the Holders of Notes affected thereby a notice briefly describing the amendment, supplement or waiver. Any failure of the Issuer to give such notice, or any defect therein, will not, however, in any way impair or affect the validity of any such amended or supplemental indenture or waiver.

Section 9.03 [Reserved].

Section 9.04 Revocation and Effect of Consents.

Until an amendment, supplement or waiver becomes effective, a consent to it by a Holder of a Note is a continuing consent by the Holder of a Note and every subsequent Holder of a Note or portion of a Note that evidences the same debt as the consenting Holder's Note, even if notation of the consent is not made on any Note. However, any such Holder of a Note or subsequent Holder of a Note may revoke the consent as to its Note if the Trustee receives written notice of revocation before the date the amendment, supplement or waiver becomes effective. An amendment, supplement or waiver becomes effective in accordance with its terms and thereafter binds every Holder.

Section 9.05 Notation on or Exchange of Notes.

The Trustee may place an appropriate notation about an amendment, supplement or waiver on any Note thereafter authenticated. The Issuer in exchange for all Notes may issue and the Trustee shall, upon receipt of an Authentication Order, authenticate new Notes that reflect the amendment, supplement or waiver.

Failure to make the appropriate notation or issue a new Note will not affect the validity and effect of such amendment, supplement or waiver.

125

Section 9.06 Section 9.06 Trustee to Sign Amendments, etc.

The Trustee will sign any amended or supplemental indenture authorized pursuant to this Article 9 if the amendment or supplement does not adversely affect the rights, duties, liabilities or immunities of the Trustee. In executing any amended or supplemental indenture, the Trustee will be entitled to receive and (subject to Section 7.01 hereof) will be fully protected in relying upon, in addition to the documents required by Sections 7.02(b) and 12.04 hereof, an Officer’s Certificate and an Opinion of Counsel stating that the execution of such amended or supplemental indenture is authorized or permitted by this Indenture.

ARTICLE X GUARANTEES

Section 10.01 Guarantee.

(a) Subject to this Article 10, each of the Guarantors hereby, jointly and severally, unconditionally Guarantees to each Holder of a Note authenticated and delivered by the Trustee and to the Trustee and its successors and assigns, irrespective of the validity and enforceability of this Indenture, the Notes or the obligations of the Issuer hereunder or thereunder, that:

(1) the principal of, premium on, if any, and interest on, the Notes will be promptly paid in full when due, whether at Stated Maturity, by acceleration, redemption or otherwise, and interest on the overdue principal of, premium on, if any, and interest on, the Notes, if lawful, and all other obligations of the Issuer to the Holders or the Trustee hereunder or thereunder will be promptly paid in full or performed, all in accordance with the terms hereof and thereof; and

(2) in case of any extension of time of payment or renewal of any Notes or any of such other obligations, that same will be promptly paid in full when due or performed in accordance with the terms of the extension or renewal, whether at Stated Maturity, by acceleration or otherwise.

Failing payment when due of any amount so Guaranteed or any performance so Guaranteed for whatever reason, the Guarantors will be jointly and severally obligated to pay the same immediately. Each Guarantor agrees that this is a Guarantee of payment and not a Guarantee of collection.

(b) The Guarantors hereby agree that their obligations hereunder are unconditional, irrespective of the validity, regularity or enforceability of the Notes or this Indenture, the absence of any action to enforce the same, any waiver or consent by any Holder of the Notes with respect to any provisions hereof or thereof, the recovery of any judgment against the Issuer, any action to enforce the same or any other circumstance which might otherwise constitute a legal or equitable discharge or defense of a guarantor. Each Guarantor hereby waives diligence, presentment, demand of payment, filing of claims with a court in the event of insolvency or bankruptcy of the Issuer, any right to require a proceeding first against the Issuer, protest, notice and all demands whatsoever and covenant that this Guarantee will not be

126

discharged except by complete performance of the obligations contained in the Notes and this Indenture.

(c) If any Holder or the Trustee is required by any court or otherwise to return to the Issuer, the Guarantors or any custodian, trustee, liquidator or other similar official acting in relation to either the Issuer or the Guarantors, any amount paid by any of them to the Trustee or such Holder, this Guarantee, to the extent theretofore discharged, will be reinstated in full force and effect.

(d) Each Guarantor agrees that it will not be entitled to any right of subrogation in relation to the Holders in respect of any obligations Guaranteed hereby until payment in full of all obligations Guaranteed hereby. Each Guarantor further agrees that, as between the Guarantors, on the one hand, and the Holders and the Trustee, on the other hand, (1) the maturity of the obligations Guaranteed hereby may be accelerated as provided in Article 6 hereof for the purposes of this Guarantee, notwithstanding any stay, injunction or other prohibition preventing such acceleration in respect of the obligations Guaranteed hereby, and (2) in the event of any declaration of acceleration of such obligations as provided in Article 6 hereof, such obligations (whether or not due and payable) will forthwith become due and payable by the Guarantors for the purpose of this Guarantee. The Guarantors will have the right to seek contribution from any non-paying Guarantor so long as the exercise of such right does not impair the rights of the Holders under the Guarantee.

Section 10.02 Limitation on Guarantor Liability.

(a) Each Guarantor, and by its acceptance of Notes, each Holder, hereby confirm that it is the intention of all such parties that the Guarantee of such Guarantor not constitute a fraudulent transfer or conveyance for purposes of Bankruptcy Law, the Uniform Fraudulent Conveyance Act, the Uniform Fraudulent Transfer Act or any similar federal, state, provincial or other applicable U.S., Canadian or foreign law to the extent applicable to any Guarantee. To effectuate the foregoing intention, the Trustee, the Holders and the Guarantors hereby irrevocably agree that the obligations of such Guarantor will be limited to the maximum amount that will, after giving effect to such maximum amount and all other contingent and fixed liabilities of such Guarantor that are relevant under such laws, and after giving effect to any collections from, rights to receive contribution from or payments made by or on behalf of any other Guarantor in respect of the obligations of such other Guarantor under this Article 10, result in the obligations of such Guarantor under its Guarantee not constituting a fraudulent transfer or conveyance.

(b) Limitation on Argentinian Guarantors.

127

right to invoke any defense of payment impossibility (including any defense under Section 1091 of the Argentine Civil and Commercial Code), impossibility of paying in U.S. dollars (assuming liability for any force majeure or act of God), or similar defenses or principles (including, without limitation, equity or sharing of efforts principles, impossibility to comply with the obligations under Section 1732 of the Argentine Civil and Commercial Code, “onerosidad sobreviniente”, “lesión enorme” or “abuso del derecho” under Section 10 of the Argentine Civil and Commercial Code). Nothing in this Indenture or the Notes shall impair any of the rights of the Holders of the Notes or justify the Argentinian Guarantors in refusing to make payments hereunder in U.S. dollars for any reason whatsoever, including, without limitation, any of the following: (i) the purchase of U.S. dollars in Argentina by any means becoming more onerous or burdensome for the Issuer and/or the Argentinian Guarantors than as of the date thereof and (ii) the exchange rate in force in Argentina increasing significantly from that in effect as of the date thereof. Accordingly, the Argentinian Guarantors assume the risk of, and take responsibility for any present or future circumstance (including circumstances that may constitute events of force majeure) that may affect the foreign exchange market or any methods for obtaining U.S. dollars, or prevent or make more burdensome the acquisition of U.S. dollars owed hereunder, and it agrees, in any event, to honor all its obligations by the delivery of the exact amount of U.S. dollars owed hereunder outside Argentina.

(2) The Argentinian Guarantors hereby agree that, if there is any restriction or prohibition to access to the Argentine foreign exchange market, or on the payment outside of Argentina of any amounts due under this Indenture or the Notes, or a requirement to have prior authorization of the Central Bank of the Republic of Argentina (Banco Central de la República Argentina) or of any other authority, and such authorization is not obtained prior to the applicable payment date, the Argentinian Guarantors shall, at its own expense, obtain the required amount of U.S. dollars to pay the relevant amount, to the extent permitted by law, through (i) the purchase of any public or private bond or tradable debt or equity security listed in Argentina and denominated in U.S. dollars, and transfer and sale of the same out of Argentina for the payment of the then-due amount in U.S. dollars; (ii) the purchase of the due amount in U.S. dollars in any market in which it may be purchased, with any legal tender; or (iii) any other lawful mechanism for the acquisition of U.S. dollars. Any payment obligations shall only be discharged upon the receipt by the Paying Agent of the full payment of all such payment obligations, in U.S. dollars. Interest shall continue to accrue as specified in this Indenture on any amounts that are not paid on the due date therefor as a result of the Argentinian Guarantors or any other entity's entering into or consummating any transaction to obtain U.S. dollars to make any required payment hereunder or under the Notes and such shall continue to accrue until full payment of such amount due is made to the Paying Agent.

(3) Without limiting the generality of any other provision of this Indenture, the Argentinian Guarantors hereby irrevocably and unconditionally waive, to the fullest extent permitted by applicable law, all rights and benefits set forth in Articles 1584 (Excepciones al beneficio de excusión), 1583 (Beneficio de excusión) the first paragraph of 1585 (Beneficio de excusión en caso de coobligados), 1586 (Subsistencia del plazo),

(1) With respect to each Guarantor organized under the laws of the Kingdom of Bahrain (each, a “Bahraini Guarantor”), without prejudice to the nature of this Guarantee as a continuing guarantee for all obligations and liabilities of the Issuer under this Indenture, the liability of a Bahraini Guarantor under this Guarantee shall not exceed, at any time, the aggregate amount of Obligations outstanding under the Notes. Each Bahraini Guarantor expressly agrees (and waives any right it may have to argue to the contrary) and irrevocably acknowledges that the Trustee may make a demand under the Guarantee by such Bahraini Guarantor even after the expiration of three months from the date on which such Bahraini Guarantor has sent a notification to the Agent under Article 753 of Law No. 19 of 2001 promulgating the Bahrain Civil Code, as amended (“Bahrain Civil Code”) that the provisions of Article 753 of the Bahrain Civil Code are not applicable to the Guarantee by such Bahraini Guarantor and waives any rights it may have under Article 753.

(d) Limitation on Colombian Guarantors.

Section 10.03 Execution and Delivery of Guarantee.

To evidence its Guarantee set forth in Section 10.01 hereof, each Guarantor hereby agrees that this Indenture or a supplemental indenture in substantially the form attached as

129

Exhibit E hereto will be executed by an Officer of such Guarantor on behalf of such Guarantor by manual, electronic or facsimile signature.

Each Guarantor hereby agrees that its Guarantee set forth in Section 10.01 hereof will remain in full force and effect notwithstanding the absence of an endorsement on each Note of such Guarantee.

If an Officer whose signature is on this Indenture or supplemental indenture, as applicable, no longer holds that office at the time the Trustee authenticates the Note, the Guarantee will be valid nevertheless.

The delivery of any Note by the Trustee, after the authentication thereof hereunder, will constitute due delivery of the Guarantee set forth in this Indenture on behalf of the Guarantors.

Section 10.04 Guarantors May Consolidate, etc., on Certain Terms.

A Guarantor other than the Parent may not sell or otherwise dispose of all or substantially all of its properties or assets to, or consolidate or amalgamate with or merge with or into (whether or not such Guarantor is the surviving Person) another Person, other than the Issuer or another Guarantor, unless:

(1) immediately after giving effect to such transaction, no Default or Event of Default exists; and
(2) either:

(A) the Person acquiring the properties or assets in any such sale, exchange, transfer or other disposition or the Person formed by or surviving any such consolidation, amalgamation or merger (if other than the Guarantor) unconditionally assumes, pursuant to a supplemental indenture substantially in the form specified as Exhibit E hereto, all the obligations of that Guarantor under, the Notes, its Guarantee and this Indenture on the terms set forth herein; or
(B) such transaction does not violate Section 4.10 thereof.

In case of any such consolidation, merger, sale or disposition and upon the assumption by the successor Person, by supplemental indenture, executed and delivered to the Trustee and satisfactory in form to the Trustee, of the Guarantee of the Guarantor and the due and punctual performance of all of the covenants and conditions of this Indenture to be performed by the Guarantor, such successor Person will succeed to and be substituted for the Guarantor with the same effect as if it had been named herein as a Guarantor. Such successor Person thereupon may cause to be signed any or all of the notations of Guarantees to be endorsed upon all of the Notes issuable hereunder which theretofore shall not have been signed by the Issuer and delivered to the Trustee. All the Guarantees so issued will in all respects have the same legal rank and benefit under this Indenture as the Guarantees theretofore and thereafter issued in accordance with the terms of this Indenture as though all of such Guarantees had been issued at the date of the execution thereof.

130

Except as set forth in Articles 4 and 5 hereof, and notwithstanding Section 10.04(2)(A) and (B), nothing contained in this Indenture or in any of the Notes will prevent any consolidation or merger of a Guarantor with or into the Issuer or another Guarantor, or will prevent any sale or disposition of all or substantially all of the properties or assets of a Guarantor to the Issuer or another Guarantor.

(A) all Notes that have been authenticated, except lost, stolen or destroyed Notes that have been replaced or paid and Notes for whose payment money has been deposited in trust and thereafter repaid to the Issuer, have been delivered to the Trustee for cancellation; or

(B) all Notes that have not been delivered to the Trustee for cancellation have become due and payable or will become due and payable within one year by reason of the sending of a notice of redemption or otherwise and the Issuer or any Guarantor has irrevocably deposited or caused to be deposited with the Trustee as trust funds in trust solely for the benefit of the Holders, cash in U.S. dollars, non-callable Government Securities, or a combination of cash in U.S. dollars and non-callable Government Securities, in amounts as will be sufficient without consideration of any reinvestment of interest (which in the case of a deposit in whole or in part of non-callable Government Securities will be evidenced by the opinion of a nationally recognized firm of independent public accountants as to the sufficiency of such deposit), to pay and discharge the entire indebtedness on the Notes not delivered to the Trustee for cancellation for principal, premium, if any, and accrued interest to the date of fixed maturity or redemption; provided that upon any redemption that requires the payment of the Make Whole Premium, the amount deposited shall be sufficient for purposes of this Indenture to the extent that an amount is deposited with the Trustee that is equal to the Make Whole Premium calculated as of the date of the notice of redemption with any Make Whole Premium Deficit only required to be deposited with the Trustee on or prior to the date of redemption;

(2) in respect of Section 11.01(1)(B), no Event of Default has occurred and is continuing on the date of the deposit (other than an Event of Default resulting from the borrowing of funds to be applied to such deposit and any similar deposit relating to other Indebtedness and, in each case, the granting of Liens to secure such borrowings), and the deposit will not result in a breach or violation of, or constitute a default under, any material agreement or instrument (other than this Indenture and the agreements governing any other Indebtedness that is being defeased, discharged or replaced) to which the Parent or any of its Subsidiaries is a party or by which the Parent or any of its Subsidiaries is

132

bound (other than with respect to the borrowing of funds to be applied concurrently to make the deposit required to effect such satisfaction and discharge and any similar concurrent deposit relating to other Indebtedness, and in each case the granting of Liens to secure such borrowings);

(3) the Issuer or any Guarantor has paid or caused to be paid all sums payable by it under this Indenture; and

(4) the Issuer has delivered irrevocable instructions to the Trustee to apply the deposited money toward the payment of the Notes at fixed maturity or the redemption date, as the case may be.

In addition, the Issuer must deliver an Officer’s Certificate stating that all conditions precedent to satisfaction and discharge have been satisfied and an Opinion of Counsel (which may be subject to customary assumptions and exclusions) stating that all such conditions precedent set forth in Section 11.01(2) and (4) have been satisfied.

Notwithstanding the satisfaction and discharge of this Indenture, if funds have been deposited with the Trustee pursuant to Section 11.01(1)(B), the obligation set forth in Section 11.01(1)(B)(y) and the provisions of Sections 11.02 and 8.06 hereof will survive. In addition, nothing in this Section 11.01 will be deemed to discharge those provisions of Section 7.07 hereof, that, by their terms, survive the satisfaction and discharge of this Indenture.

Section 11.02 Application of Trust Money; Miscellaneous.

Subject to the provisions of Section 8.06 hereof, all money deposited with the Trustee pursuant to Section 11.01 hereof shall be held in trust and applied by it, in accordance with the provisions of the Notes and this Indenture, to the payment, either directly or through any Paying Agent (including the Parent or any of its Subsidiaries acting as the Paying Agent) as the Trustee may determine, to the Persons entitled thereto, of the principal, premium, if any, and interest for whose payment such money has been deposited with the Trustee; but such money need not be segregated from other funds except to the extent required by law.

If the Trustee or Paying Agent is unable to apply any money or Government Securities in accordance with Section 11.01 hereof by reason of any legal proceeding or by reason of any order or judgment of any court or governmental authority enjoining, restraining or otherwise prohibiting such application, the Issuer’s and any Guarantor’s obligations under this Indenture and the Notes shall be revived and reinstated as though no deposit had occurred pursuant to Section 11.01 hereof; provided that if the Issuer has made any payment of principal of, premium on, if any, or interest on, any Notes because of the reinstatement of their obligations, the Issuer shall be subrogated to the rights of the Holders of such Notes to receive such payment from the money or Government Securities held by the Trustee or Paying Agent.

The Issuer will pay and indemnify the Trustee against any tax, fee or other charge imposed on or assessed against the cash or non-callable Government Securities deposited pursuant to Section 11.01 hereof or the principal and interest received in respect thereof other than any such tax, fee or other charge which by law is for the account of the Holders of the outstanding Notes.

If the Issuer, Parent and/or any Guarantor, as applicable, elects to give the Trustee Instructions using Electronic Means and the Trustee in its discretion elects to act upon such Instructions, the Trustee’s understanding of such Instructions shall be deemed controlling. The Issuer, the Parent and the Guarantors understand and agree that the Trustee cannot determine the identity of the actual sender of such Instructions and that the Trustee shall conclusively presume that directions that purport to have been sent by an Authorized Officer listed on the incumbency certificate provided to the Trustee have been sent by such Authorized Officer. The Issuer, the Parent and the Guarantors shall be responsible for ensuring that only Authorized Officers transmit such Instructions to the Trustee and that the Issuer, the Parent, any Guarantor 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 Parent and/or any Guarantor, as applicable.

The Issuer, the Parent and the Guarantors agree: (i) to assume all risks arising out of the use of Electronic Means to submit Instructions to the Trustee, including without limitation the risk of the Trustee 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 Trustee and that there may be more secure methods of transmitting Instructions than the method(s) selected by the Issuer, the Parent and/or the Guarantor, as applicable; (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 Trustee immediately upon learning of any compromise or unauthorized use of the security procedures.

Any notice or communication to a Holder will be mailed by first class mail or by overnight air courier guaranteeing next day delivery to its address shown on the register kept by the Registrar, or in any case where DTC or its nominee is the Holder, any notice or communication will be given by the method specified by DTC. Failure to give a notice or communication to a Holder or any defect in it will not affect its sufficiency with respect to other Holders.

If a notice or communication is given in the manner provided above within the time prescribed, it is duly given, whether or not the addressee receives it.

If the Issuer mails a notice or communication to Holders, they will mail a copy to the Trustee and each Agent at the same time.
