Typographic and other minor errors or defects in any such facsimile signature shall not affect the validity or enforceability of any Note which has been authenticated and delivered by the Trustee.

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

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

The Trustee shall authenticate and make available for delivery the Notes for original issue in an initial aggregate principal amount of $750,000,000 and Additional Notes as contemplated by Section 2.1(c) hereof, upon receipt of a written order of the Company signed by an Officer of the Company (a “ Company Order ”).

The aggregate principal amount of Notes outstanding at any time may not exceed the applicable amounts in the foregoing sentence, except as provided in Sections 2.1(c) and 2.7 hereof.

The Company shall enter into an appropriate agency agreement with any Agent not a party to this Indenture. The agreement shall implement the provisions of this Indenture that relate to such Agent. The Company shall notify the Trustee of the name and address of any Agent not a party to this Indenture. If the Company fails to maintain a Registrar, Paying Agent or agent for service of notices and demands in any place required by this Indenture, or fail to give the foregoing notice, the Trustee shall act as such. The Company or any Affiliate of the Company may act as Paying Agent (except for the purposes of Section 4.1 and Article 8).

If the Company or an Affiliate of the Company acts as Paying Agent, the Company or such Affiliate shall, before 11:00 a.m., New York City time, on each due date of the principal of or interest on any Notes, segregate the money and hold it as a separate trust fund. The Company at any time may require a Paying Agent to pay all money held by it to the Trustee, and the Trustee may at any time during the continuance of any Default, upon written request to a Paying Agent, require such Paying Agent to pay forthwith to the Trustee all sums so held in trust by such Paying Agent. Upon doing so, the Paying Agent (other than the Company) shall have no further liability for the money. For the avoidance of doubt, in no event shall any Paying Agent (unless the Company or an Affiliate of the Company is acting as Paying Agent) be required to advance funds for any payment on the Notes hereunder or to make any such payment until the Paying Agent has actually received such funds from the Company.

Section 2.5 Noteholder Lists . The Trustee shall preserve in as current a form as is reasonably practicable the most recent list available to it of the names and addresses of Noteholders.

Any exchange or transfer shall be without charge, except that the Company or the Registrar may require payment of a sum sufficient to cover any tax or other governmental charge that may be imposed in relation thereto, and provided , that this sentence shall not apply to any exchange pursuant to Section 2.10, 2.12(a), 3.6, 3.11 or 9.5 hereof.

-26-

In case any such mutilated, destroyed, lost or stolen Note has become or is about to become due and payable, or is about to be purchased by the Company pursuant to Article 3, the Company in its discretion may, instead of issuing a new Note, pay or purchase such Note, as the case may be.

Upon the issuance of any new Notes under this Section 2.7, the Company may require the payment of a sum sufficient to cover any tax or other governmental charge that may be imposed in relation thereto and any other reasonable expenses (including the reasonable fees and expenses of the Trustee or the Registrar) in connection therewith.

Every new Note issued pursuant to this Section 2.7 in lieu of any mutilated, destroyed, lost or stolen Note shall constitute an original additional contractual obligation of the Company, whether or not the mutilated, destroyed, lost or stolen Note shall be at any time enforceable by anyone, and shall be entitled to all benefits of this Indenture equally and proportionately with any and all other Notes duly issued hereunder.

The provisions of this Section 2.7 are (to the extent lawful) exclusive and shall preclude (to the extent lawful) all other rights and remedies with respect to the replacement or payment of mutilated, destroyed, lost or stolen Notes.

Section 2.8 Outstanding Notes . Notes outstanding at any time are all Notes authenticated by the Trustee, except for those canceled by it, those delivered to it for cancellation or surrendered for transfer or exchange and those described in this Section 2.8 as not outstanding.

If a Note is replaced pursuant to Section 2.7 hereof, it ceases to be outstanding unless the Company receives proof satisfactory to it that the replaced Note is held by a bona fide purchaser.

If a Paying Agent (other than the Company or an Affiliate of the Company) holds on a Redemption Date, Change of Control Purchase Date or the Final Maturity Date money sufficient to pay the principal of (including premium, if any) and interest on Notes (or portions thereof) payable on that date, then on and after such Redemption Date, Change of Control Purchase Date or the Final Maturity Date, as the case may be, such Notes (or portions thereof, as the case may be) shall cease to be outstanding and interest on them shall cease to accrue.

Subject to the restrictions contained in Section 2.9 hereof, a Note does not cease to be outstanding because the Company or an Affiliate of the Company holds the Note.

Section 2.9 Treasury Notes . In determining whether the Holders of the required principal amount of Notes have concurred in any notice, direction, waiver or consent, Notes owned by the Company or any other obligor on the Notes or by any Affiliate of the Company or of such other obligor shall be disregarded, except that, for purposes of determining whether the Trustee shall be protected in relying on any such notice, direction, waiver or consent, only Notes which a Trust Officer of the Trustee actually knows are so owned shall be so disregarded. Notes so owned which have been pledged in good faith shall not be disregarded if the pledgee establishes to the satisfaction of the Trustee the pledgee’s right so to act with respect to the Notes and that the pledgee is neither the Company nor any other obligor on the Notes or any Affiliate of the Company or of such other obligor.

(c) Subject to the succeeding paragraph, every Note shall be subject to the restrictions on transfer provided in the Legend.

The Registrar shall not be required to accept for such registration of transfer or exchange any Note not so accompanied by a properly completed certificate.

(d) The restrictions imposed by the Legend upon the transferability of any Note shall cease and terminate when such Note has been sold pursuant to an effective registration statement under the Securities Act or transferred in compliance with Rule 144 under the Securities Act (or any successor provision thereto) or, if earlier, upon the expiration of the holding period applicable to sales thereof under Rule 144(d)(1)(ii) under the Securities Act (or any successor provision). Any Note as to which such restrictions on transfer shall have expired in accordance with their terms or shall have terminated may, upon a surrender of such Note for exchange to the Registrar in accordance with the provisions of this Section 2.12 (accompanied, in the event that such restrictions on transfer have terminated by reason of a transfer in compliance with Rule 144 or any successor provision, by, if requested by the Company or the Registrar, an opinion of counsel reasonably acceptable to the Company and addressed to the Company to the effect that the transfer of such Note has been made in compliance with Rule 144 or such successor provision), be exchanged for a new Note, of like tenor, series and aggregate principal amount, which shall not bear the restrictive Legend. The Company shall inform the Trustee of the effective date of any registration statement registering any Notes under the Securities Act. The Trustee shall not be liable for any action taken or omitted to be taken by it in good faith in accordance with the aforementioned opinion of counsel or registration statement.

(e) As used in this Section 2.12, the term “transfer” encompasses any sale, pledge, transfer, hypothecation or other disposition of any Note.

(f) The provisions of clauses (iii), (iv) and (v) below shall apply only to Global Notes:

(i) Notwithstanding any other provisions of this Indenture or the Notes, a Global Note shall not be exchanged in whole or in part for a Note registered in the name of any Person other than the Depositary or one or more nominees thereof, provided that a Global Note may be exchanged for Notes registered in the names of any person designated by the Depositary in the event that (A) the Depositary has notified the obligors that it is unwilling or unable to continue as Depositary for such Global Note and the Company fails to appoint a successor Depositary or (B) an Event of Default has occurred and is continuing with respect to the Notes. Any Global Note exchanged pursuant to clause (A) above shall be so exchanged in whole and not in part, and any Global Note exchanged pursuant to clause (B) above may be exchanged in whole or from time to time in part as directed by the applicable Depositary. Any Note issued in exchange for a Global Note or any portion thereof shall be a Global Note; provided that any such Note so issued that is registered in the name of a Person other than the applicable Depositary or a nominee thereof shall not be a Global Note.

(ii) Notes issued in exchange for a Global Note or any portion thereof shall be issued in definitive, fully registered form, without interest coupons, shall have an aggregate principal amount equal to that of such Global Note or portion thereof to be so exchanged, shall be registered in such names and shall be in such authorized denominations as the Depositary shall designate and shall bear the applicable legends provided for herein. Any Global Note to be exchanged in whole shall be surrendered by the Depositary to the Trustee, as Registrar. With regard to any Global Note to be exchanged in part, either such Global Note shall be so surrendered for exchange or, if the Trustee is acting as custodian for the Depositary or its nominee with respect to such Global Note, the principal amount thereof shall be reduced, by an amount equal to the portion thereof to be so exchanged, by means of an appropriate adjustment made on the records of the Trustee. Upon any such surrender or adjustment, the Trustee shall authenticate and deliver Notes issuable on such exchange to or upon the order of the Depositary or an authorized representative thereof.

Notwithstanding the foregoing, nothing herein shall prevent the Company, the Trustee or any agent of the Company or the Trustee from giving effect to any written certification, proxy or other authorization furnished by the Depositary or such nominee, as the case may be, or impair, as between the Depositary, its Agent Members and any other Person on whose behalf an Agent Member may act, the operation of customary practices of such Persons governing the exercise of the rights of a holder of any Note.

(C) any Designated Noncash Consideration having an aggregate Fair Market Value that, when taken together with all other Designated Noncash Consideration previously received and then outstanding, does not exceed at the time of the receipt of such Designated Noncash Consideration (with the Fair Market Value of each item of Designated Noncash Consideration being measured at the time received and without giving effect to subsequent changes in value) the greater of $800.0 million or 3.0% of Consolidated Total Assets.

(b) Within 450 days after the receipt of any Net Proceeds from an Asset Sale, Parent or the applicable Restricted Subsidiary may apply an amount equal to those Net Proceeds:

(i) to repay (w) Indebtedness and other Obligations under the Credit Agreement and, if the Indebtedness repaid under the Credit Agreement is revolving credit Indebtedness, to correspondingly reduce commitments with respect thereto, (x) other secured indebtedness, (y) other Indebtedness which ranks pari passu in right of payment with the Notes (provided in the case of this clause (y) the Company shall equally and ratably reduce obligations under the Notes in accordance with Section 3.7 hereof, through privately negotiated transactions or open market purchases (in each case, provided that such purchases are at or above 100% of the principal amount thereof), or by making an offer (in accordance with Section 4.14(c)) to all Holders to purchase, at a purchase price equal to 100% of the principal amount thereof, plus accrued and unpaid interest, the pro rata principal amount of Notes) or (z) other Indebtedness of a Subsidiary (other than the Company) that does not Guarantee the Notes, so long as the relevant assets were assets of such Subsidiary;

(ii) to acquire all or substantially all of the assets of, or a majority of the Voting Stock of, another Permitted Business or the minority interest in any Permitted Business;

(iii) to make payments with respect to the acquisition or license of intellectual property rights that are used in a Permitted Business;

(vi) to acquire other assets that are not classified as current assets (for the avoidance of doubt, including acquisitions of in-process research and development) under GAAP and that are used or useful in a Permitted Business;

provided that a binding commitment to apply any Net Proceeds from an Asset Sale as set forth in clauses (ii), (iii), (iv) or (vi) of this Section 4.14(b) shall be treated as a permitted application of the Net Proceeds from the date of such commitment so long as Parent or such Restricted Subsidiary enters into such commitment with the good faith expectation that such Net Proceeds will be applied to satisfy such commitment within 180 days of the end of such 450-day period (an “ Acceptable Commitment ”) and, in the event any Acceptable Commitment is later cancelled or

-49-

terminated for any reason before the Net Proceeds are applied in connection therewith, then Parent or such Restricted Subsidiary shall be permitted to apply the Net Proceeds in any manner set forth above before the expiration of such 180-day period and, in the event Parent or such Restricted Subsidiary fails to do so, then such Net Proceeds shall constitute Excess Proceeds.

Notwithstanding Sections 4.14(a) and 4.14(b), Parent and its Restricted Subsidiaries will not be required to apply an amount equal to any Net Proceeds in accordance with this covenant except to the extent that the aggregate Net Proceeds from all Asset Sales which are not applied in accordance with this covenant exceed the greater of $275.0 million or 1.0% of Consolidated Total Assets at the time of receipt of such Net Proceeds. Pending application of an amount equal to Net Proceeds pursuant to this Section 4.14, Parent or a Restricted Subsidiary may temporarily reduce revolving credit borrowings or otherwise invest the Net Proceeds in any manner that is not prohibited by this Indenture.

(c) Any Net Proceeds from Asset Sales that are not applied or invested as provided in Section 4.14(b) hereof shall constitute “ Excess Proceeds .” When the aggregate amount of Excess Proceeds exceeds the greater of $275.0 million or 1.0% of Consolidated Total Assets, the Company shall make an offer (an “ Asset Sale Offer ”) to all Holders of Notes and all holders of other Indebtedness that is pari passu with the Notes containing provisions similar to those set forth in this Indenture with respect to offers to purchase or redeem with the proceeds of sales of assets to purchase the maximum principal amount of Notes and such other pari passu Indebtedness that may be purchased out of the amount of such Excess Proceeds. The offer price in any Asset Sale Offer shall be equal to 100% of principal amount plus accrued and unpaid interest to, but not including, the date of purchase, and shall be payable in cash. If any Excess Proceeds remain after consummation of an Asset Sale Offer, Parent and its Restricted Subsidiaries may use the amount of such Excess Proceeds for any purpose not otherwise prohibited by this Indenture. If the aggregate principal amount of Notes and other pari passu Indebtedness tendered into such Asset Sale Offer exceeds the amount of Excess Proceeds, the Company shall select the Notes and such other pari passu Indebtedness to be purchased on a pro rata basis. Upon completion of each Asset Sale Offer, the amount of Excess Proceeds shall be reset at zero.

(d) The Company shall 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 the Asset Sale provisions of this Indenture, the Company shall comply with the applicable securities laws and regulations and shall not be deemed to have breached its obligations under the Asset Sale provisions of this Indenture by virtue of such compliance.

Section 4.15 Additional Note Guarantees . If any one of Parent’s Subsidiaries (other than the Company) that is not a Note Guarantor Guarantees any Indebtedness of Parent or any Guarantor under any syndicated Credit Facility or Capital Markets Indebtedness, that Subsidiary shall (i) execute and deliver to the Trustee a supplemental indenture in form reasonably satisfactory to the Trustee and a notation of Note Guarantee substantially in the form of Exhibit  B hereto or, in the case that such Subsidiary of Parent is a Canadian Note Guarantor, a Canadian Note Guarantee, pursuant to which such Subsidiary shall unconditionally Guarantee, on a senior secured basis, all of the Company’s obligations under the Notes and this Indenture on the terms set forth in this Indenture and, if applicable, the Canadian Note Guarantee, and (ii) deliver to the Trustee an Opinion of Counsel that such supplemental indenture and notation of Note Guarantee or, if applicable, Canadian Note Guarantee, has been duly authorized, executed and delivered by such Subsidiary and constitutes a legal, valid, binding and enforceable obligation of such Subsidiary. Thereafter, such Subsidiary shall be a Note Guarantor for all purposes hereof until such Note Guarantee is released in accordance herewith.

Notwithstanding the foregoing, the supplemental indenture and notation of Note Guarantee may be modified in respect of any Note Guarantor organized outside the United States of America as necessary or appropriate to (1) comply with applicable law, (2) avoid any general legal limitations such as general statutory limitations, financial assistance, corporate benefit, “thin capitalization” rules, retention of title claims or similar matters or (3) avoid a conflict with the fiduciary duties of such company’s directors, contravention of any legal prohibition or regulatory condition, or the material risk of personal or criminal liability for any officers or directors (collectively referred to as “ Agreed Guarantee Principles ”), in each case as determined by Parent in its sole discretion.

-50-

Section 4.16 Designation of Restricted and Unrestricted Subsidiaries . Parent’s Board of Directors may designate any Restricted Subsidiary (other than the Company) to be an Unrestricted Subsidiary if that designation would not cause a Default. Any designation of a Subsidiary as an Unrestricted Subsidiary will be deemed to be a designation of each of such entity’s Subsidiaries as Unrestricted Subsidiaries. Following the Issue Date, if a Restricted Subsidiary is designated as an Unrestricted Subsidiary, the aggregate Fair Market Value of all outstanding Investments owned by Parent and its Restricted Subsidiaries in the Subsidiary designated as an Unrestricted Subsidiary shall be deemed to be an Investment made as of the time of the designation and will reduce the amount available for Restricted Payments under Section 4.8 hereof or under one or more of the clauses of the definition of “Permitted Investments,” as determined by Parent. That designation will only be permitted if the Investment would be permitted at that time and if the Restricted Subsidiary otherwise meets the definition of an Unrestricted Subsidiary. Parent’s Board of Directors may redesignate any Unrestricted Subsidiary to be a Restricted Subsidiary if the redesignation would not cause a Default; provided that such redesignation will be deemed to be an incurrence of Indebtedness and, if applicable, an incurrence of related Liens by a Restricted Subsidiary of Parent of any outstanding Indebtedness and, if applicable, related Liens of such Unrestricted Subsidiary and such redesignation will only be permitted if such Indebtedness and, if applicable, related Liens are permitted under Section 4.9 hereof and, if applicable, Section 4.11 hereof (other than clause (3) under the definition of “Permitted Liens”), calculated, if applicable, on a pro forma basis as if such designation had occurred at the beginning of the four-quarter reference period.

Section 4.17 Business Activities . Parent shall not, and shall not permit any of its Restricted Subsidiaries to, engage in any business other than Permitted Businesses, except to such extent as would not be material to Parent and its Restricted Subsidiaries, taken as a whole.

Section 4.18 [ Reserved ].

Section 4.19 Stay, Extension and Usury Laws . The Company covenants (to the extent that it may lawfully do so) that it shall 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 or other law which would prohibit or forgive the Company from paying all or any portion of the principal of, premium, if any, or interest on the Notes as contemplated herein, wherever enacted, now or at any time hereafter in force, or which may affect the covenants or the performance of this Indenture, and the Company (to the extent it may lawfully do so) hereby expressly waives all benefit or advantage of any such law and covenant 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 had been enacted.

Section 4.20 Notice of Default . In the event that any Default or Event of Default under Section 6.1 hereof shall occur, the Company shall give prompt written notice of such Default or Event of Default to the Trustee after it becomes aware of the same.

Section 4.21 Payment of Additional Amounts .

(a) All payments made by or on behalf of any Note Guarantor, other than a Note Guarantor organized in the United States, any state thereof or the District of Columbia, under or with respect to any Note Guarantee (each such Person, a “ Payor ”) will be made free and clear of any withholding or deduction for or on account of any tax, duty, levy, impost, assessment or other governmental charge of whatever nature (collectively, “ Tax ”) imposed or levied by or on behalf of any jurisdiction in which such Payor is organized, resident or carrying on business for tax purposes or from or through which such Payor makes any payment on its Note Guarantee or any department or political subdivision of any of the foregoing (each, a “ Relevant Taxing Jurisdiction ”), unless the Payor (or an applicable withholding agent) is required to withhold or deduct Taxes by law. For the avoidance of doubt, a Relevant Taxing Jurisdiction shall not include the United States, any state thereof or the District of Columbia. If the Payor (or an applicable withholding agent) is required by law to withhold or deduct any amount for or on account of Taxes of a Relevant Taxing Jurisdiction from any payment made under or with respect to any Note Guarantee, the Payor, subject to the exceptions listed below, will pay additional amounts (“ Additional Amounts ”) as may be necessary to ensure that the net amount received by each Holder or beneficial owner of the Notes after such withholding or deduction (including withholding or deduction attributable to Additional Amounts payable hereunder) will not be less than the amount the Holder or beneficial owner would have received if such Taxes had not been required to be so withheld or deducted.

-51-

(b) A Payor will not, however, pay Additional Amounts to a Holder or beneficial owner of Notes:

(i) to the extent the Taxes giving rise to such Additional Amounts would not have been imposed but for the existence of any present or former connection between the Holder or beneficial owner (or between a fiduciary, settler, beneficiary, member or shareholder of, or possessor of a power over, such Holder or beneficial owner, if such Holder or beneficial owner is an estate, trust, partnership or corporation) and the Relevant Taxing Jurisdiction (other than any connection resulting solely from the acquisition, ownership, holding or disposition of Notes, the receipt of payments thereunder or under any Note Guarantee and/or the exercise or enforcement of rights under any Notes or any Note Guarantee);

(ii) to the extent the Taxes giving rise to such Additional Amounts would not have been imposed but for the failure of the Holder or beneficial owner of Notes, following the Company’s or the Payor’s written request addressed to the Holder, to the extent such Holder or beneficial owner is legally eligible to do so, to comply with any certification, identification, information or other reporting requirements, whether required by statute, treaty, regulation or administrative practice of a Relevant Taxing Jurisdiction, as a precondition to exemption from, or reduction in the rate of deduction or withholding of, Taxes imposed by the Relevant Taxing Jurisdiction (including, without limitation, a certification that the Holder or beneficial owner is not resident in the Relevant Taxing Jurisdiction);

(iii) with respect to any estate, inheritance, gift, sales, transfer, capital gains, excise or personal property tax or any similar Taxes;

(iv) to the extent the Taxes giving rise to such Additional Amounts would not have been imposed but for the presentation by the Holder or beneficial owner of any Note, where presentation is required, for payment on a date more than 30 days after the date on which payment became due and payable or the date on which payment thereof is duly provided for, whichever occurs later;

(v) to the extent the Taxes giving rise to such Additional Amounts would not have been imposed but for the Holder or beneficial owner not dealing at arm’s length, within the meaning of the Income Tax Act (Canada), with such Payor; or

(vi) any combination of items (i), (ii), (iii), (iv) and (v).

Additional Amounts also shall not be paid with respect to any payment on any Note Guarantee to a beneficial owner who is a fiduciary, a partnership (or entity treated as a partnership for tax purposes) or anyone other than the sole beneficial owner of that payment to the extent that payment would be required by the laws of the Relevant Taxing Jurisdiction to be included in the income, for tax purposes, of a beneficiary or settlor with respect to the fiduciary, a member of that partnership or a beneficial owner who would not have been entitled to the Additional Amounts had that beneficiary, settlor, member or interest holder been the beneficial owner.

(c) The Payor or applicable withholding agent will (i) make any such withholding or deduction required by applicable law and (ii) timely remit the full amount deducted or withheld to the relevant authority in accordance with applicable law. The Payor, or the applicable withholding agent, will make reasonable efforts to obtain certified copies of tax receipts evidencing the payment of any Taxes so deducted or withheld from each Relevant Taxing Jurisdiction imposing such Taxes. The Payor, or the applicable withholding agent, will provide to the Trustee, within a reasonable time after the date the payment of any Taxes so deducted or withheld are due pursuant to applicable law, either a certified copy of tax receipts evidencing such payment, or, if such tax receipts are not reasonably available to the Payor, such other documentation that provides reasonable evidence of such payment by the Payor.

-52-

(d) Where Tax is payable pursuant to Regulation 803 of the Income Tax Act (Canada) by a Holder or beneficial owner of the Notes in respect of any amount payable under any Note Guarantee to the Holder (other than by reason of a transfer of the Notes to a person resident in Canada with whom the transferor does not deal at arm’s length for the purposes of such Act), but no Additional Amount is paid in respect of such Tax, the Payor will pay as or on account of interest to the Holder an amount equal to such Tax (a “ Regulation 803 Reimbursement ”) plus an amount equal to any Tax required to be paid by the Holder or beneficial owner as a result of such Regulation 803 Reimbursement within 45 days after receiving from the Holder a notice containing reasonable particulars of the Tax so payable, provided such Holder or beneficial owner would have been entitled to receive Additional Amounts on account of such Tax (and only to the extent of such Additional Amounts that such Holder or beneficial owner would have been entitled to receive) but for the fact that it is payable otherwise than by deduction or withholding from payments made under or with respect to any Note Guarantee.

(e) The Payor will deliver to the Trustee an Officers’ Certificate stating that such Additional Amounts will be payable prior to the date on which such payments will be made, and the amounts so payable, and will set forth such other information necessary to enable the Trustee (or applicable paying agent) to pay such Additional Amounts to Holders on the payment date. Any such Officers’ Certificate will be delivered at least two Business Days in advance of when the payments in question are required to be made (unless a shorter period of time is acceptable to the Trustee in its reasonable discretion). The Payor will promptly publish a notice in accordance with Section 11.2 hereof stating that such Additional Amounts will be payable and describing the obligation to pay such amounts.

(f) The Payors, jointly and severally, will reimburse the Holders or beneficial owners of Notes, upon written request of such Holder or beneficial owner of Notes and certified proof of payment for the amount of (i) any Taxes levied or imposed by a Relevant Taxing Jurisdiction and payable by such Holder or beneficial owner in connection with payments made under or with respect to any Note Guarantee; and (ii) any Taxes levied or imposed with respect to any reimbursement under the foregoing clause (i) or this clause (ii), so that the net amount received by such Holder or beneficial owner after such reimbursement will not be less than the net amount such Holder or beneficial owner would have received if the Taxes giving rise to the reimbursement described in clauses (i) and/or (ii) had not been imposed, provided , however , that the indemnification obligation provided for in this Section 4.21(f) shall not extend to Taxes imposed for which the Holder or beneficial owner of the Notes would not have been eligible to receive payment of Additional Amounts hereunder by virtue of clauses (i) through (vi) of Section 4.21(b) hereof, or to the extent such Holder or beneficial owner received Additional Amounts with respect to such payments.

(g) In addition, the Payor will pay any stamp, issue, registration, court, documentary, excise or other similar taxes, charges and duties, including interest and penalties with respect thereto, imposed by any Relevant Taxing Jurisdiction at any time in respect of the execution, issuance, registration or delivery of any Note Guarantee or any other document or instrument referred to thereunder and any such taxes, charges or duties imposed by any Relevant Taxing Jurisdiction at any time as a result of, or in connection with, (i) any payments made pursuant to any Note Guarantee or any other such document or instrument referred to thereunder and/or (ii) the enforcement of any Note Guarantee or any other such document or instrument referred to thereunder.

(h) The obligations described under this Section 4.21 will survive any termination, defeasance or discharge of this Indenture and will apply mutatis mutandis to any successor Person, to any Payor and to any jurisdiction in which such successor is organized (other than the United States, any state thereof or the District of Columbia), carrying on business or is otherwise resident for Tax purposes or any jurisdiction (other than the United States, any state thereof or the District of Columbia) from or through which payment is made by such successor or its respective agents.

(i) Whenever this Indenture refers to, in any context, the payment of principal, premium, if any, interest or any other amount payable under any Note Guarantee, such reference includes the payment of Additional Amounts or other payments that would be payable pursuant to this Section 4.21, if applicable.

Any notice given pursuant to Section 6.1(d) hereof must be in writing and must specify the Default, demand that it be remedied and state that the notice is a “ Notice of Default .” When any Default under this Section 6.1 is cured, it ceases.

Section 6.2 Acceleration . If an Event of Default (other than an Event of Default specified in clause (i) or (j) of Section 6.1 hereof with respect to the Company) with respect to the Notes occurs and is continuing, the Trustee may, by notice to the Company, or the Holders of at least 25% in aggregate principal amount of the Notes then outstanding may, by notice to the Company and the Trustee, declare all unpaid principal to the date of acceleration on the Notes then outstanding (if not then due and payable) to be due and payable upon any such declaration, and the same shall become and be immediately due and payable. If an Event of Default specified in clause (i) or (j) of Section 6.1 hereof with respect to the Company occurs, all unpaid principal (including, without limitation, any premium, if any, then outstanding), and accrued interest, if any, on the Notes then outstanding shall ipso facto become and be immediately due and payable without any declaration or other act on the part of the Trustee or any Holder. The Holders of a majority in aggregate principal amount of Notes then outstanding by notice to the Trustee may rescind an acceleration and its consequences if (a) all existing Events of Default, other than the nonpayment of the principal of Notes which has become due solely by such declaration of acceleration, have been cured or waived; (b) the rescission would not conflict with any judgment or decree of a court of competent jurisdiction; and (c) all payments due to the Trustee and any predecessor Trustee under Section 7.7 hereof in respect of the Notes have been made. No such rescission shall affect any subsequent default or impair any right consequent thereto.

Section 6.3 Other Remedies .

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 Noteholder 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.

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

(b) reduce the principal of or change the Stated Maturity of any such Note or alter the provisions with respect to the redemption of such Notes (excluding, for the avoidance of doubt, provisions relating to Sections 3.8, 3.14 and 4.14 hereof);

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

(d) make any such Note payable in money other than U.S. dollars;

(e) make any change in the provisions of this Indenture relating to waivers of past Defaults or the rights of Holders of such Notes to receive payments of principal of, or interest or premium, if any, on such Notes;

(f) waive a redemption payment with respect to any such Note (excluding, for the avoidance of doubt, a payment required by Sections 3.8, 3.14 and 4.14 hereof);

(g) impair the right to institute suit for the enforcement of any payment on or with respect to such Notes;

(h) modify the Note Guarantees with respect to such Notes in any manner adverse to the Holders of such Notes; or

(i) make any change in the preceding amendment and waiver provisions with respect to the Notes;

provided that the written consent of the Holders of at least a majority in aggregate principal amount of the Notes then outstanding shall be required.

In addition, without the consent of Holders of at least 66  ² ⁄ ₃ % in principal amount of the Notes then outstanding (including, without limitation, consents obtained in connection with a purchase of, or tender offer or exchange offer for, Notes), except as set forth in Section 10.5 hereof, no amendment or supplement may release the Note Guarantees with respect to the Notes.

It shall not be necessary for the consent of the Holders under this Section 9.2 to approve the particular form of any proposed amendment, supplement or waiver, but it shall be sufficient if such consent approves the substance thereof.

-67-

Section 9.3 Notice of Amendment, Supplement or Waiver . After an amendment, supplement or waiver under Section 9.1 or Section 9.2 becomes effective, the Company shall mail to the Holders affected thereby a notice briefly describing the amendment, supplement or waiver. Any failure of the Company to mail such notice, or any defect therein, shall not, however, in any way impair or affect the validity of any such amendment, supplement or waiver.

Section 9.4 Revocation and Effect of Consents . Until an amendment, supplement or waiver becomes effective, a consent to it by a Holder is a continuing consent by the Holder 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 or subsequent Holder may revoke the consent as to its Note or portion of a Note if the Trustee receives the notice of revocation before the date the amendment, supplement or waiver becomes effective.

After an amendment, supplement or waiver becomes effective, it shall bind every Holder, unless it makes a change described in any of clauses (a) through (i) of Section 9.2 hereof. In that case the amendment, supplement or waiver shall bind each Holder of a Note who has consented to it and every subsequent Holder of a Note or portion of a Note that evidences the same debt as the consenting Holder’s Note.

Section 9.5 Notation on or Exchange of Notes . If an amendment, supplement or waiver changes the terms of a Note, the Trustee may require the Holder of the Note to deliver it to the Trustee. The Trustee may place an appropriate notation on the Note about the changed terms and return it to the Holder. Alternatively, if the Company or the Trustee so determines, the Company in exchange for the Note shall issue and the Trustee shall authenticate a new Note that reflects the changed terms.

Section 9.6 Trustee to Sign Amendments, Etc . The Trustee shall sign any amendment or supplemental indenture authorized pursuant to this Article 9 if the amendment or supplemental indenture does not adversely affect the rights, duties, liabilities or immunities of the Trustee. If it does, the Trustee may, in its sole discretion, but need not sign it. In signing or refusing to sign such amendment or supplemental indenture, the Trustee shall be provided with and, subject to Section 7.1 hereof, shall be fully protected in relying upon, an Opinion of Counsel and an Officers’ Certificate stating that such amendment or supplemental indenture is authorized or permitted by this Indenture and all conditions precedent in this Indenture to such execution have been complied with. The Company may not sign an amendment or supplemental indenture until its Board of Directors approves it in writing.

Section 9.7 Effect of Supplemental Indentures . Upon the execution of any supplemental indenture under this Article 9, this Indenture shall be modified in accordance therewith, and such supplemental indenture shall form a part of this Indenture for all purposes; and every Holder of Notes theretofore or thereafter authenticated and delivered hereunder shall be bound thereby.

(a) Each of the Note Guarantors, jointly and severally, hereby unconditionally Guarantees (and subject in each case to the Agreed Guarantee Principles set forth in any notation of Note Guarantee, supplemental indenture, or as contemplated by Section 4.15 hereof) 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 Company hereunder or thereunder that: (i) the due and punctual payment of principal, premium and interest on the Notes shall be promptly paid in full when due, whether at maturity, by acceleration, redemption or otherwise, (ii) the due and punctual payment of interest on the overdue principal of and interest on the Notes, if any, if lawful, and all other obligations of the Company to the Holders or the Trustee under this Indenture or any Note shall be promptly paid in full or performed, all in accordance with the terms hereof and thereof, and (iii) in case of any extension of time of payment or renewal of any Notes or any of such other obligations, that same shall be promptly paid in full when due or performed in accordance with the terms

(b) Each of the Note Guarantors hereby agrees that its obligations with regard to its Guarantee shall be joint and several, unconditional, irrespective of the validity or enforceability of the Notes or the obligations of the Company under this Indenture, the absence of any action to enforce the same, the recovery of any judgment against the Company or any other obligor with respect to this Indenture, the Notes or the obligations of the Company under this Indenture or the Notes, any action to enforce the same or any other circumstances (other than complete performance) which might otherwise constitute a legal or equitable discharge or defense of a Note Guarantor. Each Note Guarantor further, to the extent permitted by law, hereby waives and relinquishes all claims, rights and remedies accorded by applicable law to guarantors and agrees not to assert or take advantage of any such claims, rights or remedies, including but not limited to: (i) any right to require any of the Trustee, the Holders or the Company (each a “ Benefited Party ”), as a condition of payment or performance by such Note Guarantor, to (A) proceed against the Company, any other guarantor (including any other Note Guarantor) of the obligations under the Note Guarantees or any other person, (B) proceed against or exhaust any security held from the Company, any such other guarantor or any other person, (C) proceed against or have resort to any balance of any deposit account or credit on the books of any Benefited Party in favor of the Company or any other person, or (D) pursue any other remedy in the power of any Benefited Party whatsoever; (ii) any defense arising by reason of the incapacity, lack of authority or any disability or other defense of the Company including any defense based on or arising out of the lack of validity or the unenforceability of the obligations under the Note Guarantees or any agreement or instrument relating thereto or by reason of the cessation of the liability of the Company from any cause other than payment in full of the obligations under the Note Guarantees; (iii) any defense based upon any statute or rule of law which provides that the obligation of a surety must be neither larger in amount nor in other respects more burdensome than that of the principal; (iv) any defense based upon any Benefited Party’s errors or omissions in the administration of the obligations under the Note Guarantees, except behavior which amounts to bad faith; (v) (A) any principles or provisions of law, statutory or otherwise, which are or might be in conflict with the terms of the Note Guarantees and any legal or equitable discharge of such Note Guarantor’s obligations hereunder and under its Note Guarantee, (B) the benefit of any statute of limitations affecting such Note Guarantor’s liability hereunder and under its Note Guarantee or the enforcement hereof and thereof, (C) any rights to set-offs, recoupments and counterclaims and (D) promptness, diligence and any requirement that any Benefited Party protect, secure, perfect or insure any security interest or lien or any property subject thereto; (vi) notices, demands, presentations, protests, notices of protest, notices of dishonor and notices of any action or inaction, including acceptance of the Note Guarantees, notices of default under the Notes or any agreement or instrument related thereto, notices of any renewal, extension or modification of the obligations under the Note Guarantees or any agreement related thereto, and notices of any extension of credit to the Company and any right to consent to any thereof; (vii) to the extent permitted under applicable law, the benefits of any “One Action” rule; and (viii) any defenses or benefits that may be derived from or afforded by law which limit the liability of or exonerate guarantors or sureties, or which may conflict with the terms of the Note Guarantees. Except as set forth in Section 10.5 hereof, each Note Guarantor covenants that its Note Guarantee shall not be discharged except by complete performance of the obligations contained in its Note Guarantee and this Indenture.

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

(d) Each Note Guarantor agrees that it shall not be entitled to any right of subrogation in relation to the Holders in respect of any obligations guaranteed hereby until payment in full of all obligations guaranteed hereby. Each Note Guarantor shall further agree that, as between the Note Guarantors, on the one hand, and the Holders and the Trustee, on the other hand, (i) the maturity of the obligations guaranteed hereby may be accelerated as provided in Section 6.2 hereof for the purposes of any Guarantee, notwithstanding any stay, injunction or other prohibition preventing such acceleration in respect of the obligations guaranteed hereby and (ii) in the event of any declaration of acceleration of such obligations as provided in Section 6.2 hereof, such obligations (whether or not due and payable) shall forthwith become due and payable by the Note Guarantors for the purpose of any such Guarantee. The Note Guarantors shall have the right to seek contribution from any non-paying Note Guarantor so long as the exercise of such right does not impair the rights of the Holders under the applicable Guarantee.

-69-

Section 10.2 Execution and Delivery of Note Guarantees . To evidence its Guarantee set forth in Section 10.1 hereof, each Note Guarantor hereby agrees that a notation of such Note Guarantee substantially in the form of Exhibit  B hereto (as modified to reflect Agreed Guarantee Principles to the extent contemplated by Section 4.15 hereof) or, in the case of a Note Guarantor organized under the laws of Canada or any province or territory thereof, a Canadian Note Guarantee, shall be endorsed by an officer of such Note Guarantor, which notation shall be applicable to each Note authenticated and delivered by the Trustee, and that this Indenture shall be executed on behalf of such Note Guarantor by any of its Officers. Each of the Note Guarantors, jointly and severally, hereby agrees that its Guarantee set forth in Section 10.1 hereof shall remain in full force and effect notwithstanding any failure to endorse a notation of such Note Guarantee. If an officer or Officer whose signature is on this Indenture or on the Note Guarantee of a Note Guarantor no longer holds that office at the time the Trustee authenticates a Note, the Note Guarantee of such Note Guarantor shall be valid nevertheless. The delivery of any Note by the Trustee, after the authentication thereof hereunder, shall constitute due delivery of the Note Guarantees set forth in this Indenture on behalf of the Note Guarantors.

Section 10.3 Limitation on Note Guarantor Liability . Each Note Guarantor confirms, and by its acceptance of Notes, each Holder hereby confirms, that it is the intention of all such parties that any Guarantee of such Note 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 applicable law to the extent applicable to any Note Guarantee. To effectuate the foregoing intention, the Trustee and the Holders irrevocably agree, and the Note Guarantors irrevocably agree, that the obligations of such Note Guarantor under this Article 10 shall be limited to the maximum amount as will, after giving effect to such maximum amount and all other contingent and fixed liabilities of such Note 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 Note Guarantor in respect of the obligations of such other Note Guarantor under this Article 10, result in the obligations of such Note Guarantor under its Note Guarantee not constituting a fraudulent transfer or conveyance.

Section 10.4 Merger and Consolidation of Note Guarantors .

(a) In case of any sale or other disposition, consolidation, amalgamation, merger, sale or conveyance 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 Note Guarantee endorsed upon the Notes and the due and punctual performance of all of the covenants and conditions of this Indenture to be performed by the Note Guarantor, such successor person shall succeed to and be substituted for the Note Guarantor with the same effect as if it had been named herein as a Note Guarantor. Such successor person thereupon may cause to be signed any or all of the Note Guarantees to be endorsed upon all of the Notes available hereunder which theretofore shall not have been signed by the Company and delivered to the Trustee. All the Note Guarantees so issued shall in all respects have the same legal rank and benefit under this Indenture as the Note Guarantees theretofore and thereafter issued in accordance with the terms of this Indenture as though all of such Note Guarantees had been issued at the date of the execution hereof.

(b) Except as set forth in Articles 4 and 5 hereof, and notwithstanding clause (a) of this Section 10.4, nothing contained in this Indenture or in any of the Notes shall prevent any consolidation, amalgamation or merger of a Note Guarantor with or into another Person, or shall prevent any sale or conveyance of the property of a Note Guarantor as an entirety or substantially as an entirety.

Section 10.5 Release .
