For these purposes, rental payments do not include any amounts required to be paid for taxes, maintenance, repairs, insurance, assessments, utilities, operating and labor costs and other items that do not constitute payments for property rights. In the case of any lease that the lessee may terminate by paying a penalty, if the net amount (including payment of the penalty) would be reduced if the lessee terminated the lease on the first date that it could be terminated, then this lower net amount will be used.

“Change of Control” means the occurrence of any of the following after the date of issuance of the Notes:

(d)          during any period of twelve (12) consecutive calendar months, individuals who were members of the Board of Directors on the first day of such period cease to constitute a majority of the Board of Directors unless such new directors were approved by a majority of the directors who were directors on the first day of such period; or

The Trustee shall make the selection from the Notes outstanding not previously called for redemption. The Trustee may select for redemption portions of the principal of the Notes that have denominations greater than a principal amount of $2,000. Securities of the Series and portions of them it selects shall be in amounts of $1,000 or whole multiples of $1,000 or, with respect to Securities of any Series issuable in other denominations pursuant to Section 2.2.10, the minimum principal denomination for each Series and the authorized integral multiples thereof. Provisions of this Indenture that apply to Securities of a Series called for redemption also apply to portions of Securities of that Series called for redemption.”

SECTION 2.9.  Optional Redemption. A new Section 3.7 shall be added after Section 3.6 of the Base Indenture, which shall read as follows:

“Section 3.7 Optional Redemption.

(a)          Prior to December 1, 2033 (three months prior to their maturity date) (the “Par Call Date”), the Company may redeem the Notes at its option, in whole or in part, at any time and from time to time, at a redemption price (expressed as a percentage of principal amount and rounded to three decimal places) equal to the greater of (i)(a) the sum of the present values of the remaining scheduled payments of principal and interest thereon discounted to the redemption date (assuming the Notes matured on the Par Call Date) on a semi-annual basis (assuming a 360-day year consisting of twelve 30-day months) at the Treasury Rate plus 15 basis points, less (b) interest accrued to the date of redemption, and (ii) 100% of the principal amount of the Notes to be redeemed, plus, in the case of either clause (i) or (ii), accrued and unpaid interest thereon to the redemption date.

(b)          On or after the Par Call Date, the Company may redeem the Notes, in whole or in part, at any time and from time to time, at a redemption price equal to 100% of the principal amount of the Notes being redeemed plus accrued and unpaid interest thereon to the redemption date.

(c)          The Treasury Rate shall be determined by the Company after 4:15 p.m., New York City time (or after such time as yields on U.S. government securities are posted daily by the Board of Governors of the Federal Reserve System), on the third business day preceding the redemption date based upon the yield or yields for the most recent day that appear after such time on such day in the most recent statistical release published by the Board of Governors of the Federal Reserve System designated as “Selected Interest Rates (Daily) — H.15” (or any successor designation or publication) (“H.15”) under the caption “U.S. government securities — Treasury constant maturities — Nominal” (or any successor caption or heading) (“H.15 TCM”) (such rate, the “Treasury Rate”). In determining the Treasury Rate, the Company shall select, as applicable: (i) the yield for the Treasury constant maturity on H.15 exactly equal to the period from the redemption date to the Par Call Date (the “Remaining Life”); or (ii) if there is no such Treasury constant maturity on H.15 exactly equal to the Remaining Life, the two yields — one yield corresponding to the Treasury constant maturity on H.15 immediately shorter than and one yield corresponding to the Treasury constant maturity on H.15 immediately longer than the Remaining Life — and shall interpolate to the Par Call Date on a straight-line basis (using the actual number of days) using such yields and rounding the result to three decimal places; or (iii) if there is no such Treasury constant maturity on H.15 shorter than or longer than the Remaining Life, the yield for the single Treasury constant maturity on H.15 closest to the Remaining Life. For purposes of this Section 3.7(c), the applicable Treasury constant maturity or maturities on H.15 shall be deemed to have a maturity date equal to the relevant number of months or years, as applicable, of such Treasury constant maturity from the redemption date.

If on the third business day preceding the redemption date H.15 TCM or any successor designation or publication is no longer published, the Company shall calculate the Treasury Rate based on the rate per annum equal to the semi-annual equivalent yield to maturity at 11:00 a.m., New York City time, on the second business day preceding such redemption date of the United States Treasury security maturing on, or with a maturity that is closest to, the Par Call Date, as applicable. If there is no United States Treasury security maturing on the Par Call Date but there are two or more United States Treasury securities with a maturity date equally distant from the Par Call Date, one with a maturity date preceding the Par Call Date and one with a maturity date following the Par Call Date, the Company shall select the United States Treasury security with a maturity date preceding the Par Call Date. If there are two or more United States Treasury securities maturing on the Par Call Date or two or more United States Treasury securities meeting the criteria of the preceding sentence, the Company shall select from among these two or more United States Treasury securities the United States Treasury security that is trading closest to par based upon the average of the bid and asked prices for such United States Treasury securities at 11:00 a.m., New York City time. In determining the Treasury Rate in accordance with the terms of this paragraph, the semi-annual yield to maturity of the applicable United States Treasury security shall be based upon the average of the bid and asked prices (expressed as a percentage of principal amount) at 11:00 a.m., New York City time, of such United States Treasury security, and rounded to three decimal places.

The Company’s actions and determinations in determining the redemption price shall be conclusive and binding for all purposes, absent manifest error.

(d)          In the case of a partial redemption, selection of the Notes for redemption will be made pro rata, by lot or by such other method as the Trustee in its sole discretion deems appropriate and fair. No Notes of a principal amount of $2,000 or less will be redeemed in part. If any Note is to be redeemed in part only, the notice of redemption that relates to the Note will state the portion of the principal amount of the Note to be redeemed. A new Note in a principal amount equal to the unredeemed portion of the Note will be issued in the name of the holder of the Note upon surrender for cancellation of the original Note. For so long as the Notes are held by DTC (or another depositary), the redemption of the Notes shall be done in accordance with the policies and procedures of the Depositary.

(e)          Unless the Company defaults in payment of the redemption price, on and after the redemption date interest will cease to accrue on the Notes or portions thereof called for redemption.

(f)           Notice of any redemption of Notes may, at the Company’s discretion, be given subject to one or more conditions precedent, including, but not limited to, completion of a corporate transaction that is pending (such as an equity or equity-linked offering, an incurrence of indebtedness or an acquisition or other strategic transaction involving a change of control in the Company or another entity). If such redemption is so subject to satisfaction of one or more conditions precedent, such notice shall describe each such condition, and such notice may be rescinded in the event that any or all such conditions shall not have been satisfied or otherwise waived on or prior to the business day immediately preceding the relevant redemption date.

The Company shall notify holders of any such rescission as soon as practicable after the Company determines that such conditions precedent will not be able to be satisfied or the Company is not able or willing to waive such conditions precedent, in each case subject to applicable procedures of DTC. Once notice of redemption is mailed or sent, subject to the satisfaction of any conditions precedent provided in the notice of redemption, the Notes called for redemption will become due and payable on the redemption date and at the applicable redemption price as set forth in this Section 3.7.

(g)          The Company is entitled to redeem the Notes then outstanding, at its option, at any time, in whole but not in part, upon not less than 15 nor more than 60 days’ prior notice, with a copy to the Trustee, to the registered address of each Holder (such notice to be provided not more than 90 days before the next date on which the Company would be obligated to pay Additional Amounts), at a redemption price equal to 100% of the principal amount thereof, plus accrued and unpaid interest, if any, to, but excluding, the redemption date (subject to the right of Holders of Notes of record on the relevant record date to receive interest due on an interest payment that is on or prior to the redemption date), in the event the Company becomes, or will become, obligated to pay, on the next date on which any amount may be payable with respect to the Notes, any Additional Amounts as a result of (i) a change in, or amendment to, the laws or regulations of any Relevant Taxing Jurisdiction or (ii) a change in any official position or the introduction of an official position regarding the application or interpretation thereof (including a holding by a court of competent jurisdiction), which is publicly announced and becomes effective on or after the issue date of the Notes and such Additional Amounts cannot (as certified in an Officer’s Certificate to the Trustee) be avoided by the use of reasonable measures available to the Company. Notice of the Company’s intent to redeem the Notes pursuant to this Section 3.7(g) shall not be effective until such time as it delivers to the Trustee an (1) Officer’s Certificate stating that the Company is entitled to effect such redemption and setting forth a statement of facts showing that the conditions precedent to such right of redemption have occurred and (2) opinion of independent legal counsel stating that the Company is or will become obligated to pay Additional Amounts because of an amendment to or change in law or regulation or position as set forth in this Section 3.7(g).”

SECTION 2.10.  Limitation on Liens. A new Section 4.6 shall be added after Section 4.5 in the Base Indenture, which shall read as follows:

“Section 4.6         Limitation on Liens.

(a)           The Company will not, and will not permit any of its Restricted Subsidiaries to, create, incur, assume or suffer to exist, directly or indirectly, any Indebtedness secured by a Security Interest upon any Principal Property of the Company or of a Restricted Subsidiary, whether owned as of the date of this Indenture or hereafter acquired, without making effective provision (and the Company hereby covenants that in any such case it shall make or cause to be made effective provision) whereby the Notes then outstanding and any other Indebtedness of the Company or any Restricted Subsidiary then entitled thereto shall be secured by such Security Interest equally and ratably with (or prior to) any and all other Indebtedness of the Company or any Restricted Subsidiary thereby secured for so long as any such other Indebtedness of the Company or any Restricted Subsidiary shall be so secured; provided, that nothing in this Section 4.6 shall prevent, restrict or apply to Indebtedness secured by:

(xv)        any extension, renewal or refunding (or successive extensions, renewals or refundings) in whole or in part of any Indebtedness secured by any Security Interest referred to in the foregoing clauses (i) through (xiv), inclusive, provided that the Security Interest securing such Indebtedness shall be limited to the property or assets which, immediately prior to such extension, renewal or refunding, secured such Indebtedness and additions to such property or assets, and the principal amount of such refinancing Indebtedness secured by such Security Interest does not exceed (x) the principal amount of such Indebtedness being refinanced plus (y) the aggregate amount of fees, underwriting discounts, accrued and unpaid interest, premiums and other costs and expenses incurred in connection with such above-referenced refinancings.

Notwithstanding the foregoing provisions of this Section 4.6(a), the Company or any of its Restricted Subsidiaries may create, incur, assume or suffer to exist any Indebtedness secured by a Security Interest without so securing the Notes if, at the time such Security Interest becomes a Security Interest upon any Principal Property of the Company or such Restricted Subsidiary and after giving effect thereto, the aggregate outstanding principal amount of all Indebtedness of the Company and its Restricted Subsidiaries secured by Security Interests and permitted by this sentence (including the Attributable Debt in respect of Sale and Leaseback Transactions, but excluding Attributable Debt in respect of any Sale and Leaseback Transactions the proceeds of which have been applied in accordance with Section 4.7(b)) does not exceed 15% of Consolidated Tangible Assets.

(b)           In the event that the Company shall hereafter secure the Notes equally and ratably with or prior to any other obligation or Indebtedness pursuant to the provisions of this Section 4.6, the Trustee is hereby authorized to enter into an indenture or agreement supplemental hereto and to take such action, if any, as it may deem advisable to enable it to enforce effectively the rights of the Holders of the Notes so secured, equally and ratably with or prior to such other obligations or Indebtedness.”

SECTION 2.11.  Limitations on Sale and Leaseback Transactions. A new Section 4.7 shall be added after the newly added Section 4.6 of the Base Indenture, which shall read as follows:

“Section 4.7         Limitations on Sale and Leaseback Transactions.

The Company will not, and will not permit any Restricted Subsidiary to, enter into any arrangement with any person providing for the leasing to the Company or any Restricted Subsidiary of any Principal Property owned or hereafter acquired by the Company or such Restricted Subsidiary (except for temporary leases for a term of not more than three years and except for leases between the Company and a Restricted Subsidiary or between Restricted Subsidiaries), which Principal Property has been or is to be sold or transferred by the Company or such Restricted Subsidiary to such person (herein referred to as a “Sale and Leaseback Transaction”) unless:

(a)          the Company or such Restricted Subsidiary would be permitted pursuant to Section 4.6 to incur Indebtedness secured by a Security Interest on the Principal Property to be leased, in an aggregate principal amount equal to the Attributable Debt associated with such Sale and Leaseback Transaction, without equally and ratably securing the Notes;

(b)          within 180 days after the effective date of the Sale and Leaseback Transaction, the Company applies an amount equal to the fair value (as determined by the Board of Directors) of such Principal Property to be leased to the redemption or retirement of the Notes and/or any other Securities issued under the Indenture or to the payment or other retirement of other Indebtedness of the Company that ranks senior to or pari passu with the Notes or of Indebtedness incurred by any Restricted Subsidiary (other than, in either case, Indebtedness owned by the Company or any Restricted Subsidiary); or

(c)          within 180 days after entering into the Sale and Leaseback Transaction, the Company enters into a bona fide commitment or commitments to expend for the acquisition or capital improvement of a Principal Property an amount at least equal to the fair value (as determined by the Board of Directors) of such Principal Property to be leased.

Notwithstanding the foregoing, the Company may, and may permit any Restricted Subsidiary to, effect any Sale and Leaseback Transaction that is not allowable under clauses (a) through (c) of this Section 4.7 if, at the time of such Sale and Leaseback Transaction, the Attributable Debt associated with such Sale and Leaseback Transaction, together with the aggregate principal amount of outstanding Indebtedness secured by Security Interests upon Principal Property pursuant to the last sentence of Section 4.6(a), does not exceed 15% of Consolidated Tangible Assets. The calculation of such aggregate principal amount of outstanding Indebtedness secured by Security Interests upon Principal Property shall exclude (i) the aggregate amount of fees, underwriting discounts, accrued and unpaid interest, premiums and other costs and expenses incurred in connection with any refinancing and (ii) any Attributable Debt in connection with which the Company has purchased property, retired or defeased Indebtedness as described in Section 4.7(b).”

SECTION 2.12.  Withholding Taxes and Other Taxes. A new Section 4.8 shall be added after the newly added Section 4.7 of the Base Indenture, which shall read as follows:

“Section 4.8         Withholding Taxes and Other Taxes.

(a)           All payments made by or on behalf of the Company under or with respect to the Notes will be made without withholding or deduction for, or on account of, any present or future tax, duty, assessment or other governmental charge (including penalties, interest and other liabilities related thereto) (“Taxes”) imposed or levied by or on behalf of (1) the government of Canada or any province or territory of Canada, (2) any other jurisdiction in which the Company is organized or otherwise is resident for tax purposes or (3) any jurisdiction from or through which payment is made, in each case including any political subdivision or any authority or agency therein or thereof having power to tax (each, a “Relevant Taxing Jurisdiction”), unless required by law or the interpretation or administration thereof. If the Company is obligated to withhold or deduct any amount on account of Taxes imposed by a Relevant Taxing Jurisdiction from any payment made under or with respect to the Notes, the Company shall:

(i)           make such withholding or deduction;

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

(iii)         subject to the limitations in Section 4.8(b), pay such additional amounts (“Additional Amounts”) as additional interest as may be necessary so that the net amounts received by each Holder, after such withholding or deduction (including any such withholding or deduction on such Additional Amounts) will not be less than the amount such Holder would have received if such Taxes had not been withheld or deducted;

(iv)         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 applicable law, certified copies of an official receipt of the relevant government authority for all amounts deducted or withheld pursuant to applicable law, or if such receipts are not reasonably obtainable, other documentation evidencing the remittance by the Company of those Taxes; and

(v)          at least 15 days prior to each date on which any Additional Amounts are payable, deliver to the Trustee an Officer’s Certificate setting forth the calculation of the Additional Amounts to be paid and such other information as the Trustee may request to enable the Trustee to pay such Additional Amounts to Holders of Notes on the payment date.

(b)          Notwithstanding the foregoing Section 4.8(a), no Additional Amounts will be paid with respect to or in respect of a payment made to or in respect of any Holder or beneficial owner of the Notes (an “Excluded Holder”):

(i)           with which the Company does not deal at arm’s length (within the meaning of the Income Tax Act (Canada)) at the time of making such payment;

(ii)          for or on account of Canadian withholding Taxes imposed on a payment under or with respect to a Note that is deemed under subsection 214(16) of the Income Tax Act (Canada) (or any similar successor provision or equivalent provision of any provincial or territorial law) to be a dividend;

(iii)         for or on account of any Taxes that are imposed or withheld as a result of the presentation of any Note for payment (where presentation is required) by or on behalf of a Holder or beneficial owner who would have been able to avoid such Taxes by presenting the relevant Note to another Paying Agent;

(iv)         which is subject to such Taxes by reason of the Holder or the beneficial owner of the Note (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 solely by the mere acquisition, holding or disposition of the Notes or the receipt of payments or enforcement of rights thereunder;

(v)          for or on account of any Taxes imposed or deducted or withheld by reason of the failure of the Holder or beneficial owner of the Note to complete, execute and deliver to the Company, any reasonable form or document concerning such Holder’s or beneficial owner’s nationality, citizenship, residence, identity or connection with the Relevant Taxing Jurisdiction, provided (1) such form or document is required by law (including any applicable tax treaty) or by reason of the interpretation or administration of such law in order to enable the Company to make payments on the Note without deduction or withholding for Taxes, or with deduction or withholding of a lesser amount, and (2) the Company has provided a timely written request to the Holder for such form or document;

(vi)         for or on account of any Taxes imposed 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);

(vii)        for or on account of any estate, inheritance, gift, sales, transfer, excise, personal property or similar Tax;

(viii)       for or on account of any Tax that is payable otherwise than by withholding 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);

(ix)          if the Holder is a fiduciary, partnership or person other than the sole beneficial owner of that payment, to the extent that such payment would be required to be included in income under the laws of the Relevant Taxing Jurisdiction 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 such Additional Amounts had that beneficiary, settlor, member or beneficial owner been the Holder of the Note;

(x)           for or on account of any Tax imposed pursuant to Sections 1471 through 1474 of the Code (including any amended or successor version), any current or future regulations or official interpretations thereof, any fiscal or regulatory legislation, rules or practices adopted pursuant to an intergovernmental agreement, treaty or convention 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;

(xi)          for or on account of any Taxes imposed by the United States or any political subdivision thereof; or

(xii)         for or on account of any combination of the exceptions listed in clauses (i) through (xi) immediately above.

(c)           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 Company’s obligation to make payments of Additional Amounts will survive any termination of this Indenture or the defeasance of any rights hereunder.

(d)           Without duplication of the foregoing, the Company shall indemnify and hold harmless each Holder and beneficial owner of Notes (other than an Excluded Holder), and upon written request therefor, shall reimburse each such Holder and beneficial owner (without duplication), for the full amount of (x) any Taxes imposed by a Relevant Taxing Jurisdiction and paid by such Holder or beneficial owner as a result of payments made under or with respect to the Notes and (y) any Taxes levied or imposed and paid by such Holder or beneficial owner with respect to any reimbursement under (x) above, but excluding any such Taxes on or computed by reference to such Holder’s or beneficial owner’s net income, revenue, profits or capital.

(e)           Without duplication of the foregoing, the Company shall pay any present or future stamp, issue, registration, court or documentary taxes or any other excise, property or similar Taxes that arise in any Relevant Taxing Jurisdiction from the execution, delivery, issuance, registration or enforcement of the Notes, this Indenture or any other document or instrument in relation thereto, and the Company shall indemnify the Holders and beneficial owners of the Notes for any such amounts (including penalties, interest and other liabilities related thereto) paid by such Holders and beneficial owners.

(f)            Each Holder or beneficial owner of the Notes shall cooperate with the Company and the Trustee to provide any information or documentation reasonably requested by the Company or the Trustee in connection with the foregoing and to assist the Company or the Trustee in determining the applicable withholding tax rate and the amount of Additional Amounts or indemnity payments payable in respect thereof (though the foregoing shall impose no obligation on the Trustee other than pursuant to applicable laws or regulations).”

SECTION 2.13.  When the Company May Merge, Amalgamate, Etc. The first paragraph of Section 5.1 of the Base Indenture shall be amended and restated in its entirety to read as follows:

“The Company shall not, in a single transaction or through a series of related transactions, consolidate with or merge or amalgamate with or into, or convey, transfer or lease all or substantially all of its properties and assets to, any person (a “successor person”) if such transaction or series of transactions, in the aggregate, would result in a conveyance, transfer or lease of all or substantially all of the properties and assets of the Company and its Restricted Subsidiaries on a consolidated basis to any successor person, unless:

(a)          the Company is the surviving corporation or the successor person (if other than the Company) is a corporation organized and validly existing under the laws of Canada or any province or territory thereof or any U.S. domestic jurisdiction and assumes by supplemental indenture the Company’s obligations under the Notes and the Indenture; and

(b)          immediately after giving effect to such transaction, no default or event of default shall have occurred and be continuing.”

5.000% Senior Notes due 2034

This Security is one of a duly authorized issue of Securities of the Company designated as its 5.000% Senior Notes due 2034 (herein called the “Securities”), initially in aggregate principal amount to $750,000,000, issued under and subject to the terms of an indenture (herein called the “Indenture”) dated as of November 16, 2018, between the Company and U.S. Bank Trust Company, National Association, as successor in interest to U.S. Bank National Association, as trustee (herein called the “Trustee,” which term includes any successor trustee under the Indenture), as supplemented by an Eighth Supplemental Indenture, dated as of February 21, 2024, between the Company and the Trustee to which the Indenture reference is hereby made for a statement of the respective rights, limitations of rights, duties, obligations and immunities thereunder of the Company, the Trustee and the Holders of the Securities, and of the terms upon which the Securities are, and are to be, authenticated and delivered.

This Security is subject to optional redemption and a special tax redemption, and may be the subject of an offer to purchase, as further described in the Indenture. The Company shall not be required to make mandatory redemption or sinking fund payments with respect to the Securities. In the event of redemption of this Security in accordance with the Indenture in part only, a new Security or Securities in principal amount equal to the unredeemed portion hereof shall be issued in the name of the Holder hereof upon the cancellation hereof.

Upon the occurrence of a Change of Control Triggering Event with respect to the Securities, unless the Company has exercised its right to redeem the Securities pursuant to Article III of the Indenture, each Holder of the Securities shall have the right to require the Company to purchase all or a portion (such that (i) any such portion to be purchased must be an integral multiple of $1,000 and (ii) the principal amount of any Note remaining after such purchase must equal $2,000 or an integral multiple of $1,000 in excess thereof) of such Holder’s Security pursuant to Article XII of the Indenture.

If an Event of Default shall occur and be continuing, the principal amount of all the Securities may be declared due and payable in the manner and with the effect provided in the Indenture.

The Indenture contains provisions for defeasance at any time of (a) the entire Indebtedness on the Securities and (b) certain covenants and Events of Default, in each case upon compliance with certain conditions set forth therein.

The Indenture permits, with certain exceptions (including certain amendments permitted without the consent of any Holders and certain amendments which require the consent of all of the Holders) as therein provided, the amendment thereof and the modification of the rights and obligations of the Company and the rights of the Holders under the Indenture and the Securities at any time by the Company and the Trustee with the consent of the Holders of at least a majority in aggregate principal amount of the Securities at the time Outstanding that are affected. The Indenture also contains provisions permitting the Holders of at least a majority in aggregate principal amount of the Securities (100% of the Holders in certain circumstances) at the time Outstanding that are affected, to waive compliance by the Company with certain provisions of the Indenture and the Securities and certain past Defaults and Events of Default under the Indenture and the Securities and their consequences. Any such consent, amendment or waiver by or on behalf of the Holder of this Security, once effective, shall be conclusive and binding upon every Holder affected by such amendment or waiver, with certain exceptions, and upon all future Holders of this Security and of any Security issued upon the registration of transfer hereof or in exchange herefor or in lieu hereof whether or not notation of such consent or waiver is made upon this Security.

No reference herein to the Indenture and no provision of this Security or of the Indenture shall alter or impair the obligation of the Company or any other obligor on the Securities (in the event such other obligor is obligated to make payments in respect of the Securities), which is absolute and unconditional, to pay the principal of, and premium, if any, and interest, if any, on, this Security at the times, place, and rate, and in the coin or currency, herein prescribed without the consent of the Holder of this Security.

As provided in the Indenture and subject to certain limitations therein set forth, the transfer of this Security is registrable in the register that the Registrar shall keep with respect to the Securities and to their transfer and exchange, upon surrender of this Security for registration of transfer at the office or agency of the Company at the Corporate Trust Office, and thereupon one or more new Securities, of authorized denominations and for the same aggregate principal amount, will be issued to the designated transferee or transferees.

Except as indicated in the Indenture, no service charge shall be made for any registration of transfer or exchange of Securities, but the Company may require payment of a sum sufficient to cover any tax or other governmental charge payable in connection therewith.

A director, officer, employee or stockholder (past or present), as such, of the Company shall not have any liability for any obligations of the Company under the Securities or the Indenture or for any claim based on, in respect of or by reason of such obligations or their creation. By accepting a Security, each Holder waives and releases all such liability. The waiver and release are part of the consideration for the issue of the Securities.

Prior to due presentment of this Security for registration of transfer, the Company, the Trustee and any agent of the Company or the Trustee may treat the person in whose name this Security is registered as the owner hereof for all purposes, whether or not this Security is overdue, and neither the Company, the Trustee nor any such agent shall be affected by notice to the contrary.

The Company, the Trustee and any Agent shall treat a person as the Holder of such principal amount of outstanding Notes represented by a Global Security as shall be specified in a written statement of the Depositary or by the applicable procedures of such Depositary with respect to such Global Security, for purposes of obtaining any consents, declarations, waivers or directions required to be given by the Holders pursuant to the Indenture.

THIS SECURITY SHALL BE DEEMED TO BE A CONTRACT MADE UNDER THE LAWS OF THE STATE OF NEW YORK AND THIS SECURITY SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK.
