Alcoa subsidiaries issue $2.6B for proposed South32 deal

Alcoa Corporation (AA) subsidiaries Alumina Pty Ltd and Alcoa Nederland Holding B.V. completed offerings on September 23, 2026, of $1.5 billion of 6.625% senior notes due 2034 and $1.1 billion of 6.875% senior notes due 2036.

Rhea-AI Filing Summary

Alcoa Corporation (AA) subsidiaries Alumina Pty Ltd and Alcoa Nederland Holding B.V. completed offerings on September 23, 2026, of $1.5 billion of 6.625% senior notes due 2034 and $1.1 billion of 6.875% senior notes due 2036. Alcoa and certain subsidiaries guarantee the notes on a senior unsecured basis. At the issuers’ option, redemptions may begin September 30, 2029 for the 2034 notes and September 30, 2031 for the 2036 notes.

Net proceeds, together with cash on hand, are intended to fund the approximately $3.1 billion cash portion of consideration for Alcoa’s proposed acquisition of South32 Limited’s interests in bauxite, alumina and aluminum operations, and related fees and expenses. The acquisition remains subject to South32 shareholder approval, required regulatory approvals and customary closing conditions. If it is not completed by the later applicable Conditions Precedent End Date (initially June 29, 2027), or the Deed is terminated or Alcoa or an issuer notifies a trustee before completion that closing will not occur by then, each issuer must redeem its notes at 100% of initial issue price plus accrued and unpaid interest. Alcoa terminated all remaining commitments under its 364-day bridge term loan facility.

Filing Explained

The indentures also impose a separate contingent payment obligation: after a change of control is completed, if during the trigger period one rating agency lowers the notes’ rating and a rating agency rates them below investment grade, the issuer must offer to repurchase them for 101% of principal plus accrued, unpaid interest.

Special Mandatory Redemption financial

"such redemption, the “Special Mandatory Redemption”"

A special mandatory redemption is a contractual obligation that forces a company to repay certain debt or preferred shares early when a specific trigger event occurs (for example, a change in tax law, regulatory change, or sale). For investors it matters because it ends the expected income stream and returns principal at a pre-set price, potentially altering returns, tax outcomes and a company’s cash needs — like a lender calling a loan back when rules change.

make-whole redemption price financial

"at a “make-whole” redemption price set forth in the applicable Indenture"

The make-whole redemption price is the amount an issuer pays to buy back debt early that compensates bondholders for the interest they will miss out on. It is usually calculated by taking the present value of the remaining scheduled payments, discounted at a specified rate (often a Treasury yield plus a spread), sometimes with a small premium — like refunding a prepaid service by reimbursing the remaining value today. It matters because it determines how much bondholders receive if the debt is called and affects the issuer’s cost of early repayment.

Change of Control Repurchase Event financial

"“Change of Control Repurchase Event” means"

A change of control repurchase event happens when a company is sold or otherwise taken over and that sale triggers contractual rights for holders of stock, options, or debt to force the company to buy their securities back for cash. Think of it like a lease that lets the tenant cash out when the building is sold: it gives certain investors a predictable exit price and timeline. This matters because it can change who owns the company, alter cash on hand, affect future returns and dilution, and influence how attractive a takeover or investment looks.

Rule 144A regulatory

"in accordance with Rule 144A under the Securities Act"

Rule 144A is a regulation that makes it easier for companies to sell private bonds to large investors without going through all the usual rules that apply to public sales. It matters because it helps companies raise money more quickly and privately, often attracting big investors looking for special deals.

The 2034 Notes were issued pursuant to an indenture dated as of September 23, 2026 (the “2034 Notes Indenture”) among (i) the 2034 Notes Issuer, (ii) the Company, (iii) certain subsidiaries of the Company, and (iv) The Bank of New York Mellon Trust Company, N.A., as trustee (the “2034 Notes Trustee”), and the 2036 Notes were issued pursuant to an indenture dated as of September 23, 2026 (the “2036 Notes Indenture” and, together with the 2034 Notes Indenture, each an “Indenture” and together, the “Indentures”) among (i) the 2036 Notes Issuer, (ii) the Company, (iii) certain subsidiaries of the Company, and (iv) The Bank of New York Mellon Trust Company, N.A., as trustee (the “2036 Notes Trustee” and, together with the 2034 Notes Trustee, each a “Trustee”). The Notes are guaranteed on a senior unsecured basis by the Company and its subsidiaries that are party to the 2034 Notes Indenture, in the case of the 2034 Notes, and its subsidiaries that are party to the 2036 Notes Indenture, in the case of the 2036 Notes.

Each Indenture contains certain restrictive covenants that limit the applicable Issuer’s and each applicable guarantor’s ability to, among other things, create liens on certain assets to secure debt; consolidate, merge, sell or otherwise dispose of all or substantially all of their assets; and enter into certain sale and leaseback transactions. These covenants are subject to a number of limitations and exceptions. Each Indenture also contains customary events of default.

The Notes may be redeemed at the applicable Issuer’s option, in whole or in part, at any time and from time to time on or after September 30, 2029, in the case of the 2034 Notes, and September 30, 2031, in the case of the 2036 Notes, at the applicable redemption prices set forth in the applicable Indenture. At any time prior to such date, the applicable Issuer will be entitled at its option to redeem all, but not less than all, of the 2034 Notes or the 2036 Notes, as applicable, at a “make-whole” redemption price set forth in the applicable Indenture. At any time prior to September 30, 2029, the applicable Issuer may, on one or more occasions, redeem up to 40% of the aggregate principal amount of the 2034 Notes or 2036 Notes, as applicable, at the applicable redemption prices set forth in the applicable Indenture with the net cash proceeds of certain equity offerings. The 2034 Notes may also be redeemed at the option of the 2034 Notes Issuer and the 2036 Notes may also be redeemed at the option of the 2036 Notes Issuer at any time in connection with certain changes in withholding taxes. If a change of control repurchase event occurs, the 2034 Notes Issuer must offer to purchase the 2034 Notes and the 2036 Notes Issuer must offer to purchase the 2036 Notes, as applicable, at a purchase price in cash equal to 101% of the principal amount thereof on the date of purchase, plus accrued and unpaid interest.

The Notes and related guarantees were sold in a private placement to qualified institutional buyers in accordance with Rule 144A under the Securities Act of 1933, as amended (the “Securities Act”), and to certain non-United States persons in offshore transactions in accordance with Regulation S under the Securities Act.

The Issuers intend to use the net proceeds of the issuance of the Notes, together with cash on hand, to fund the approximately $3.1 billion cash portion of the consideration for the previously announced proposed acquisition by the Company (the “Acquisition”) of South32 Limited’s (“South32”) interests in certain bauxite, alumina and aluminum smelter operations pursuant to the Umbrella Implementation Deed (as it may be amended or otherwise modified from time to time, the “Deed”), dated as of June 30, 2026, and to pay related fees and expenses.

Each Indenture contains customary events of default. Failure to make the Special Mandatory Redemption with respect to the 2034 Notes, if required in accordance with the terms described above, will constitute an event of default with respect to the 2034 Notes, and failure to make the Special Mandatory Redemption with respect to the 2036 Notes, if required in accordance with the terms described above, will constitute an event of default with respect to the 2036 Notes. If an event of default with respect to the 2034 Notes or the 2036 Notes, as applicable, occurs and is continuing, the applicable Trustee or the holders of at least 30% in principal amount of the 2034 Notes or the 2036 Notes, as applicable, then outstanding may declare the principal of and accrued but unpaid interest on all the 2034 Notes or the 2036 Notes, as applicable, to be immediately due and payable.

(e)Without limiting the foregoing, a Holder entitled to take any action hereunder with regard to any particular Note may do so with regard to all or any part of the principal amount of such Note or by one or more duly appointed agents, each of which may do so pursuant to such appointment with regard to all or any part of such principal amount. Any notice given or action taken by a Holder or its agents with regard to different parts of such principal amount pursuant to this paragraph shall have the same effect as if given or taken by separate Holders of each such different part.

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

ARTICLE 2.

THE NOTES

SECTION 2.1 Form and Dating.

(a)The (i) Original Notes and the Trustee’s certificate of authentication and (ii) any Additional Notes (if issued as Transfer Restricted Notes) and the Trustee’s certificate of authentication shall be substantially in the form of Exhibit A hereto, as applicable, which is hereby incorporated in and expressly made a part of this Indenture. The Notes may have notations, legends or endorsements required by law, stock exchange rule, agreements to which the Issuer or any Guarantor is subject, if any, or usage (provided that any such notation, legend or endorsement is in a form acceptable to the Issuer but which notation, legend or endorsement does not affect the rights, duties or obligations of the Trustee). Each Note shall be dated the date of its authentication. The Notes shall be issuable only in registered form without interest coupons and only in denominations of $200,000 and whole multiples of $1,000 in excess thereof. The terms of the Notes set forth in the Exhibits hereto are part of the terms of this Indenture. However, to the extent any provision of any Note conflicts with the express provisions of this Indenture, the provisions of this Indenture shall govern and be controlling. The Notes issued on the Issue Date shall be (A) offered and sold by the Issuer pursuant to the Purchase Agreement and (B) resold, initially only to (1) QIBs in reliance on Rule 144A and (2) Persons other than U.S. Persons (as defined in Regulation S) in reliance on Regulation S. Such Notes may thereafter be transferred to, among others, QIBs and purchasers in reliance on Regulation S. Additional Notes offered after the Issue Date may be offered and sold by the Issuer from time to time in accordance with the provisions of this Indenture and applicable law.

(b)Global Notes. Notes offered and sold in their initial distribution in reliance on Rule 144A shall be issued in the form of one or more global notes in registered form, bearing the applicable legends set forth in Exhibit A, without interest coupons attached (“Rule 144A Global Notes”) deposited with the Trustee as custodian for the Depositary and registered in the name of Cede & Co., as nominee for the Depositary, duly executed by the Issuer and authenticated by the Trustee as herein provided, for credit by the Depositary to the respective accounts of beneficial owners of the Notes represented thereby (or such other accounts as they may direct). Notes offered and sold in their initial distribution in reliance on Regulation S shall be issued in the form of one or more global securities in fully registered form, bearing the applicable legends set forth in Exhibit A, without interest coupons attached (“Regulation S Global Notes”), deposited with the Trustee as custodian for the Depositary and registered in the name of Cede & Co., as nominee for the Depositary, duly executed by the Issuer and authenticated by the Trustee as herein provided, for credit by the Depositary to the respective accounts of beneficial owners of the Notes represented thereby (or such other accounts as they may direct). Rule 144A Global Notes and Regulation S Global Notes are referred to herein

-36-

collectively as “Global Notes”. Beneficial interests in a Rule 144A Global Note may be transferred to a Person who takes delivery in the form of an interest in a Regulation S Global Note, whether before or after the expiration of the Restricted Period, only if the transferor first delivers to the Trustee a written certificate to the effect that such transfer is being made in accordance with Rule 903 or 904 of Regulation S or Rule 144 (if applicable). The aggregate principal amount of the Global Notes may from time to time be increased or decreased by adjustments made on the records of the Custodian and the Depositary or its nominee and on the schedules thereto as hereinafter provided.

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

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

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

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

SECTION 2.2 Execution and Authentication. One Officer shall sign the Notes for the Issuer by manual or electronic signature. 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 or electronically signs the certificate of authentication on the Note. The signature shall be conclusive evidence that the Note has been authenticated under this Indenture.

On the Issue Date, upon receipt of an Issuer Order, the Trustee shall authenticate and deliver $1,500,000,000 of Original Notes and, at any time and from time to time thereafter, the Trustee shall authenticate and deliver Additional Notes in an aggregate principal amount specified in an Issuer Order. Such Issuer Order shall specify the amount of the Additional Notes to be authenticated and the date on which the issue of Additional Notes is to be authenticated.

-37-

The aggregate principal amount of Notes which may be authenticated and delivered under this Indenture is unlimited.

The Trustee may appoint an authenticating agent reasonably acceptable to the Issuer to authenticate the Notes. Any such appointment shall be evidenced by an instrument signed by a Trust Officer, a copy of which shall be furnished to the Issuer. Unless limited by the terms of such appointment, an authenticating agent may authenticate Notes whenever the 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 any Registrar, Paying Agent or agent for service of notices and demands.

SECTION 2.3 Registrar and Paying Agent.

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

(b)The Issuer shall enter into an appropriate agency agreement with any Registrar, Paying Agent or co-registrar not a party to this Indenture. The agreement shall implement the provisions of this Indenture that relate to such agent. The Issuer shall notify the Trustee in writing of the name and address of any such agent. If the Issuer fails to maintain a Registrar or Paying Agent, the Trustee shall act as such and shall be entitled to appropriate compensation and indemnification therefor pursuant to Section 7.6. The Issuer or any of its wholly owned subsidiaries organized under the laws of the United States or any state thereof may act as Paying Agent (prior to an Event of Default), Registrar, co-registrar or transfer agent.

(c)The Issuer may remove any Registrar or Paying Agent upon written notice to such Registrar or Paying Agent and to the Trustee; provided, however, that no such removal shall become effective until (i) acceptance of an appointment by a successor as evidenced by an appropriate agreement entered into by the Issuer and such successor Registrar or Paying Agent, as the case may be, and delivered to the Trustee and the passage of any waiting or notice periods required by the procedures of the Depositary or (ii) written notification to the Trustee that the Trustee shall serve as Registrar or Paying Agent until the appointment of a successor in accordance with clause (i) above. The Registrar or Paying Agent may resign at any time upon 30 days’ written notice to the Issuer and the Trustee.

SECTION 2.4 Paying Agent To Hold Money in Trust. No later than the Business Day prior to each due date of the principal, premium, if any, and interest on any Note, the Issuer shall deposit with the Paying Agent (or if the Issuer or a wholly owned subsidiary is acting as Paying Agent, segregate and hold in trust for the benefit of the Persons entitled thereto) a sum sufficient to pay such principal, premium, if any, and interest when so becoming due. The Issuer shall require each Paying Agent (other than the Trustee) to agree in writing that the Paying

-38-

Agent shall hold in trust for the benefit of Holders or the Trustee all money held by the Paying Agent for the payment of principal of or premium, if any, or interest on the Notes and shall notify the Trustee in writing of any default by the Issuer in making any such payment. If the Issuer or a subsidiary acts as Paying Agent, it shall segregate the money held by it as Paying Agent and hold it as a separate trust fund. The Issuer at any time may require a Paying Agent to pay all money held by it to the Trustee and to account for any funds disbursed by the Paying Agent. Upon complying with this Section 2.4, the Paying Agent shall have no further liability for the money delivered to the Trustee.

SECTION 2.5 Holder Lists. The Trustee shall preserve in as current a form as is reasonably practicable the most recent list available to it of the names and addresses of Holders. If the Trustee is not the Registrar, the Issuer shall furnish to the Trustee, in writing at least five Business Days before each Interest Payment Date and at such other times as the Trustee may 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 Holders.

SECTION 2.6 Transfer and Exchange.

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

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

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

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

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

(ii)in the case of Transfer Restricted Notes that are Definitive Registered Notes, are being transferred or exchanged pursuant to an effective registration statement under the Securities Act or pursuant to clause (A), (B) or (C) below, and are accompanied by the following additional information and documents, as applicable:

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

-39-

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

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

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

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

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

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

(c)Transfer and Exchange of Global Notes. The transfer and exchange of Global Notes or beneficial interests therein shall be effected through the Depositary, in accordance with this Indenture (including applicable restrictions on transfer set forth herein, if any) and the procedures of the Depositary therefor. A transferor of a beneficial interest in a Global Note shall deliver a written order given in accordance with the Depositary’s procedures containing information regarding the participant account of the Depositary to be credited with a

-40-

beneficial interest in such Global Note or another Global Note and such account shall be credited in accordance with such order with a beneficial interest in the applicable Global Note and the account of the Person making the transfer shall be debited by an amount equal to the beneficial interest in the Global Note being transferred. Transfers by an owner of a beneficial interest in the Rule 144A Global Note to a transferee who takes delivery of such interest through the Regulation S Global Note, whether before or after the expiration of the Restricted Period, shall be made only upon receipt by the Trustee of (1) a certification in the form provided on the reverse side of the Notes from the transferor to the effect that such transfer is being made in accordance with Regulation S or (if available) Rule 144 under the Securities Act and (2) if the Issuer so requests, an Opinion of Counsel or other evidence reasonably satisfactory to it as to the compliance with the restrictions set forth in the legend set forth in Section 2.6(e)(i).

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

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

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

(i)Prior to the expiration of the Restricted Period, interests in the Regulation S Global Note may only be held through Euroclear or Clearstream. During the Restricted Period, beneficial ownership interests in the Regulation S Global Note may only be sold, pledged or transferred through Euroclear or Clearstream in accordance with the Applicable Procedures and only (A) to the Issuer, (B) so long as such security is eligible for resale pursuant to Rule 144A, to a person whom the selling holder reasonably believes is a QIB that purchases for its own account or for the account of a QIB to whom notice is given that the resale, pledge or transfer is being made in reliance on Rule 144A, (C) in an offshore transaction in accordance with Regulation S, or (D) pursuant to an effective registration statement under the Securities Act, in each case in accordance with any applicable securities laws of the United States and any state thereof. Prior to the expiration of the Restricted Period, transfers by an owner of a beneficial interest in the Regulation S Global Note to a transferee who takes delivery of such interest through the Rule 144A Global Note shall be made only in accordance with Applicable Procedures and upon receipt by the Trustee of a written certification from the transferor of the beneficial interest in the form provided on the reverse side of the Note to the effect that such transfer is being

-41-

made to a QIB within the meaning of Rule 144A in a transaction meeting the requirements of Rule 144A. Such written certification shall no longer be required after the expiration of the Restricted Period.

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

(e)Legend.

(i)Each Note certificate evidencing the Global Notes and the Definitive Registered Notes (and all Notes issued in exchange therefor or substitution thereof) shall bear a legend in substantially the following form (the “Restricted Notes Legend”):

THIS SECURITY HAS NOT BEEN REGISTERED UNDER THE U.S. SECURITIES ACT OF 1933, AS AMENDED (THE “SECURITIES ACT”) OR THE SECURITIES LAWS OF ANY STATE OR OTHER JURISDICTIONS AND, ACCORDINGLY, MAY NOT BE OFFERED OR SOLD WITHIN THE UNITED STATES OR TO, OR FOR THE ACCOUNT OR BENEFIT OF, U.S. PERSONS EXCEPT AS SET FORTH BELOW. BY ITS ACQUISITION HEREOF, THE HOLDER (1) REPRESENTS THAT (A) IT IS A “QUALIFIED INSTITUTIONAL BUYER” (AS DEFINED IN RULE 144A UNDER THE SECURITIES ACT) OR (B) IT IS NOT A U.S. PERSON AND IS ACQUIRING THIS SECURITY IN AN OFFSHORE TRANSACTION IN COMPLIANCE WITH REGULATION S UNDER THE SECURITIES ACT, (2) AGREES THAT IT WILL NOT RESELL OR OTHERWISE TRANSFER THIS SECURITY EXCEPT (A) TO THE ISSUER, ANY GUARANTOR OR ANY OTHER SUBSIDIARY THEREOF, (B) INSIDE THE UNITED STATES TO A “QUALIFIED INSTITUTIONAL BUYER” (AS DEFINED IN RULE 144A UNDER THE SECURITIES ACT) IN COMPLIANCE WITH RULE 144A UNDER THE SECURITIES ACT, (C) OUTSIDE THE UNITED STATES IN AN OFFSHORE TRANSACTION IN COMPLIANCE WITH RULE 903 OR RULE 904 OF REGULATION S UNDER THE SECURITIES ACT, (D) PURSUANT TO THE EXEMPTION FROM REGISTRATION PROVIDED BY RULE 144 UNDER THE SECURITIES ACT (IF AVAILABLE), (E) IN ACCORDANCE WITH ANOTHER EXEMPTION FROM THE REGISTRATION REQUIREMENTS OF THE SECURITIES ACT (AND BASED UPON AN OPINION OF COUNSEL IF THE ISSUER, ANY GUARANTOR OR ANY OTHER SUBSIDIARY THEREOF SO REQUEST), OR (F) PURSUANT TO AN EFFECTIVE REGISTRATION STATEMENT UNDER THE SECURITIES ACT AND (3) AGREES THAT IT WILL GIVE TO EACH PERSON TO WHOM THIS SECURITY IS TRANSFERRED A NOTICE SUBSTANTIALLY TO THE EFFECT OF THIS LEGEND. AS USED HEREIN, THE TERMS “OFFSHORE TRANSACTION,” “UNITED STATES” AND “U.S. PERSON” HAVE THE MEANING GIVEN TO THEM BY REGULATION S UNDER THE SECURITIES ACT.

-42-

In the case of Regulation S Notes, the Notes shall be the following additional legend:

BY ITS ACQUISITION HEREOF, THE HOLDER HEREOF REPRESENTS THAT IT IS NOT A U.S. PERSON, NOR IS IT PURCHASING FOR THE ACCOUNT OF A U.S. PERSON, AND IS ACQUIRING THIS SECURITY IN AN OFFSHORE TRANSACTION IN ACCORDANCE WITH REGULATION S UNDER THE SECURITIES ACT.

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

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

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

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

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

(ii)No service charge shall be made for any registration of transfer or exchange, but the Issuer may require payment of a sum sufficient to cover any transfer tax, assessments, or similar governmental charge payable in connection therewith (other than any such transfer taxes, assessments or similar governmental charge payable upon exchanges pursuant to Sections 3.7, 4.6 and 9.4 of this Indenture).

(iii)The Issuer need not transfer or exchange any Note selected for redemption or tendered (and not withdrawn) for repurchase in connection with a Change of Control Offer, need not issue, register the transfer of or exchange any Note during the period of 15 days before the sending of a notice of redemption of

-43-

Notes to be redeemed and need not register the transfer or exchange of any Note during the period of 15 days prior to an interest payment date.

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

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

(h)No Obligation of the Trustee.

(i)The Trustee shall have no responsibility or obligation to any beneficial owner of a Global Note, a member of, or a participant in the Depositary or other Person with respect to the accuracy of the records of the Depositary or its nominee or of any participant or member thereof, with respect to any ownership interest in the Notes or with respect to the delivery to any participant, member, beneficial owner or other Person (other than the Depositary) of any notice (including any notice of redemption) or the payment of any amount, under or with respect to such Notes. All notices and communications to be given to the Holders and all payments to be made to Holders under the Notes shall be given or made only to or upon the order of the registered Holders (which shall be the Depositary or its nominee in the case of a Global Note). The rights of beneficial owners in any Global Note in global form shall be exercised only through the Depositary subject to the applicable rules and procedures of the Depositary. The Trustee may conclusively rely and shall be fully protected in relying upon information furnished by the Depositary with respect to its members, participants and any beneficial owners.

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

-44-

(iii)Transfer.

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

SECTION 2.7 Definitive Registered Notes.

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

(b)Any Global Note that is transferable to the beneficial owners thereof pursuant to this Section 2.7 shall be surrendered by the Depositary to the Trustee, to be so transferred, in whole or from time to time in part, without charge, and the Trustee shall authenticate and deliver, upon such transfer of each portion of such Global Note, an equal aggregate principal amount of Definitive Registered Notes of authorized denominations. Any portion of a Global Note transferred pursuant to this Section 2.7 shall be executed, authenticated and delivered only in denominations of $200,000 and integral multiples of $1,000 in excess thereof and registered in such names as the Depositary shall direct. Any certificated Note in the form of a Definitive Registered Note delivered in exchange for an interest in the Global Note shall, except as otherwise provided by Section 2.6(e), bear the Restricted Notes Legend.

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

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

SECTION 2.8 Replacement Notes. If a mutilated Note is surrendered to the Registrar or if a Holder claims that the Note has been lost, destroyed or wrongfully taken, the Issuer shall issue and the Trustee shall authenticate a replacement Note if the requirements of Section 8-405 of the Uniform Commercial Code are met, such that the Holder (i) notifies the Issuer and the Trustee of such loss, destruction or wrongful taking within a reasonable time after such Holder has notice of such loss, destruction or wrongful taking and the Registrar does not register a transfer prior to receiving such notification, (ii) requests a replacement Note from the

-45-

Issuer and the Trustee prior to the Note being acquired by a protected purchaser and (iii) satisfies any other reasonable requirements of the Issuer and the Trustee. If required by the Trustee or the Issuer, such Holder shall furnish an indemnity bond sufficient in the judgment of the Issuer and the Trustee to protect the Issuer, the Trustee, the Paying Agent, the Registrar and any co-registrar from any loss that any of them may suffer if a Note is replaced. The Issuer and the Trustee may charge the Holder for their expenses in replacing a Note.

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

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

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

SECTION 2.10 Temporary Notes. In the event that Definitive Registered Notes are to be issued under the terms of this Indenture, until such Definitive Registered Notes are ready for delivery, the Issuer may prepare and the Trustee, upon receipt of an Issuer Order, shall authenticate temporary Notes. Temporary Notes shall be substantially in the form of Definitive Registered Notes but may have variations that the Issuer considers appropriate for temporary Notes. Without unreasonable delay, the Issuer shall prepare and the Trustee shall authenticate Definitive Registered Notes and deliver them in exchange for temporary Notes upon surrender of such temporary Notes at the office or agency of the Issuer, without charge to the Holder.

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

SECTION 2.12 Cancellation. The Issuer at any time may deliver Notes to the Trustee for cancellation and the Trustee shall cancel such Notes in accordance with its customary procedures. The Registrar and the Paying Agent shall forward to the Trustee any Notes surrendered to them for registration of transfer, exchange or payment. The Trustee or, at the direction of the Trustee, the Registrar or the Paying Agent and no one else shall cancel and destroy (subject to the record retention requirements of the Exchange Act) all Notes surrendered for registration of transfer, exchange, payment or cancellation unless the Issuer directs the

-46-

Trustee to deliver canceled Notes to the Issuer. The Issuer may not issue new Notes to replace Notes it has redeemed, paid or delivered to the Trustee for cancellation. The Trustee shall not authenticate Notes in place of canceled Notes other than pursuant to the terms of this Indenture.

SECTION 2.13 Additional Amounts.

(a)All payments on the Notes will be made free and clear of and without withholding or deduction for or on account of any Taxes imposed or levied by or on behalf of the government of Australia, The Netherlands, the United States or, in each case, any political subdivision or any authority or agency therein or thereof having power to tax, or within any other jurisdiction in which the Issuer (or its successor), the Company (or its successor) or any Subsidiary Guarantor is organized or is otherwise resident for tax purposes or any jurisdiction from or through which payment is made (each a “Relevant Taxing Jurisdiction”), unless withholding or deduction is required by law or by the interpretation or administration thereof.

(b)If the Issuer, the Company or any Subsidiary Guarantor is so required to withhold or deduct any amount for or on account of Taxes imposed by a Relevant Taxing Jurisdiction from any payment made under or with respect to the Notes, the Issuer, the Company or such Subsidiary Guarantor will be required to pay such additional amounts (“Additional Amounts”) as may be necessary so that the net amount received by any Holder or beneficial owner (including Additional Amounts) after such withholding or deduction will not be less than the amount such Holder or beneficial owner would have received if such Taxes had not been withheld or deducted; provided, however, that the foregoing obligation to pay Additional Amounts does not apply to:

(1)any Taxes that would not have been so imposed but for the existence of any present or former connection between the relevant Holder or beneficial owner (or between a fiduciary, settlor, beneficiary, member or shareholder of, or possessor of power over, the relevant Holder, if the relevant Holder or beneficial owner is an estate, nominee, trust or corporation) and the Relevant Taxing Jurisdiction (other than the mere receipt of such payment or the ownership or holding outside of the Relevant Taxing Jurisdiction of such Note);

(2)any Taxes that would not have been imposed, withheld or deducted but for the failure by the Holder or the beneficial owner of the Note to comply with a written request of the Issuer, the Company or any Subsidiary Guarantor addressed to the Holder or the beneficial owner, after reasonable notice at least 30 days before any such Taxes would be imposed, withheld or deducted, to provide certification, information, documents or other evidence concerning the nationality, residence, identity or connection with the Relevant Taxing Jurisdiction of the Holder or such beneficial owners or to make any declaration or similar claim or satisfy any certification, identification, information or other reporting requirement relating to such matters, required by applicable law, regulation, treaty, any (multilateral) exchange of information regime, or administrative practice of, or entered into by, the Relevant Taxing Jurisdiction as a precondition to exemption from all or part of such Tax, including, for the avoidance of doubt, the failure of the Holder to provide its Australian tax file

-47-

number or Australian business number (if applicable) or evidence of an exemption from doing so;

(3)any Taxes that are payable otherwise than by deduction or withholding from a payment under or with respect to the Notes or any Notes Guarantee;

(4)any estate, succession, death, goods and services or other value added, sales, transfer, stamp, issue, registration or similar Taxes;

(5)any Taxes imposed in connection with a Note presented for payment (where presentation is permitted or required for payment) by or on behalf of a Holder or beneficial owner who would have been able to avoid such Tax by presenting the relevant Note to, or otherwise accepting payment from, another paying agent;

(6)any Taxes which would not have been imposed if the Holder had presented the Note for payment (where presentation is permitted or required for payment) within 30 days after the relevant payment was first made available for payment to the Holder (except for Additional Amounts with respect to Taxes that would have been imposed had the Holder presented the Note for payment within such 30-day period);

(7)any Taxes imposed on or with respect to a payment to a Holder that is a fiduciary or partnership or any Person other than the sole beneficial owner of such payment or Note, to the extent that a beneficiary or settlor with respect to such fiduciary, a member of such partnership or the beneficial owner of such payment or Note would not have been entitled to the Additional Amounts had such beneficiary, settlor, member or beneficial owner been the actual Holder of such Note;

(8)any Taxes imposed pursuant to Sections 1471 to 1474 of the Code (or any regulations or agreements thereunder or official interpretations thereof) also referred to as “FATCA,” any intergovernmental agreement facilitating the implementation thereof (or any law implementing such intergovernmental agreement), any successor law or regulation implementing or complying with, or introduced in order to conform to, such sections of the Code, or any agreement entered into pursuant to Section 1471(b)(1) of the Code;

(9)any Tax imposed under the Australian Tax Act (or any associated legislation) in respect of amounts on the Notes which arises in circumstances where a Holder is the Issuer’s “associate” (as that term is defined in Section 128F(9) of the Australian Tax Act);

(10)any loss, liability or cost that arises as a result of a direction or notice being given under section 255 of the Australian Tax Act or section 260-5 of Schedule 1 to the Taxation Administration Act 1953 (Cth) or any analogous provision;

-48-

(11)any Taxes imposed pursuant to the Dutch Withholding Tax Act 2021 (Wet bronbelasting 2021); or

(12)any combination of the above.

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

(d)Upon request, the Issuer will provide the Trustee with official receipts, or official information reporting forms, or other documentation evidencing the payment of the Taxes with respect to which Additional Amounts are paid. The Issuer or the applicable Guarantor will also (i) make such withholding or deduction and (ii) remit the full amount deducted or withheld to the relevant authority in accordance with applicable law.

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

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

(g)The Issuer and the Guarantors shall indemnify and hold harmless the Trustee for the amount of any Taxes in respect of which the Issuer, or any Guarantor, is required to pay Additional Amounts pursuant to Section 2.13(b) that are levied or imposed and paid by the Trustee as a result of payments made under or with respect to the Notes or any Guarantee, including any reimbursements under this Section 2.13(g).

SECTION 2.14 CUSIP Numbers. The Issuer in issuing the Notes may use “CUSIP” numbers, ISINs and “Common Code” numbers (in each case if then generally in use) and, if so, the Trustee shall use “CUSIP” numbers, ISINs and “Common Code” numbers in notices of redemption as a convenience to Holders; provided, however, that any such notice may state that no representation is made as to the correctness of such numbers either as printed on the Notes or as contained in any notice of a redemption and that reliance may be placed only on the other identification numbers printed on the Notes, and any such redemption shall not be affected by any defect in or omission of such numbers. The Issuer will advise the Trustee in writing of any change in any “CUSIP” numbers, ISINs or “Common Code” numbers applicable to the Notes.

-49-

SECTION 2.15 Issuance of Additional Notes. After the Issue Date, the Issuer will be entitled to issue Additional Notes under this Indenture, which Notes shall have identical terms as the Notes issued on the Issue Date, other than with respect to the date of issuance, issue price, original interest accrual date and original interest payment date. All the Notes issued under this Indenture shall be treated as a single class for all purposes of this Indenture including waivers, amendments, redemptions and offers to purchase; provided that, such Additional Notes will have a separate CUSIP, ISIN or other identifying number unless the Additional Notes are issued pursuant to a “qualified reopening” of the original series, are otherwise treated as part of the same “issue” of debt instruments as the original series, or are issued with less than a de minimis amount of original discount, in each case for U.S. federal income tax purposes.

With respect to any Additional Notes, the Issuer will set forth in a resolution of the Board of Directors and an Officer’s Certificate, a copy of each which shall be delivered to the Trustee along with an Opinion of Counsel pursuant to Section 11.3, the following information:

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

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

SECTION 2.16 Computation of Interest.

(a)Interest shall be computed on the basis of a 360-day year comprised of twelve 30-day months.

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

-50-

ARTICLE 3.

REDEMPTION

SECTION 3.1 Notices to the Trustee. If the Issuer elects to redeem Notes pursuant to Section 5 of the Notes or otherwise in accordance with this Indenture, it shall notify the Trustee in writing of the redemption date and the principal amount of Notes to be redeemed.

The Issuer shall give each notice to the Trustee provided for in this Section 3.1 at least 5 days before the redemption date unless the Trustee consents to a shorter period. Such notice shall be accompanied by an Officer’s Certificate and an Opinion of Counsel from the Issuer to the effect that such redemption shall comply with the conditions herein. Any such notice may be canceled by written notice of the Issuer to the Trustee at any time prior to notice of such redemption being sent to any Holder pursuant to Section 3.4 and shall thereby be void and of no effect. This Section 3.1 shall not apply to any Special Mandatory Redemption pursuant to Section 3.9.

SECTION 3.2 Selection of Notes To Be Redeemed. If fewer than all the Notes are to be redeemed, selection of the Notes for redemption will be made by lot or otherwise in accordance with DTC procedures. The Issuer will redeem Notes of $200,000 or less in whole and not in part. Notes and portions of them selected for redemption shall be in principal amounts of $200,000 or a whole multiple of $1,000 in excess thereof, to the extent practicable. Provisions of this Indenture that apply to Notes called for redemption also apply to portions of Notes called for redemption. If any Note is to be redeemed in part only, the notice of redemption that relates to that Note will state the portion of the principal amount thereof to be redeemed. If the Notes are being redeemed other than on a pro rata basis, the Trustee shall notify the Issuer promptly of the Notes or portions of Notes to be redeemed.

SECTION 3.3 Effect of Notice of Redemption. Once a notice of redemption has been mailed or otherwise delivered under Section 3.4(a) or Section 3.9, Notes that are to be redeemed in accordance with such notice and the terms of this Article 3 shall become due and payable on the redemption date, subject where applicable to the satisfaction of any conditions in connection with the redemption. With respect to registered Notes issued in global form, the principal amount of such Note or Notes will be adjusted in accordance with the Applicable Procedures. With respect to any Notes represented by certificated notes, the Issuer will issue a new Note in a principal amount equal to the unredeemed portion of the original Note in the name of the holder upon cancelation of the original Note. Upon surrender to the Paying Agent, such Notes shall be paid under the terms stated in Section 3.4 and Section 3.9, as applicable; provided that if the redemption date is after a record date for the payment of interest and on or prior to the related Interest Payment Date, the accrued interest shall be payable to the Holder of the redeemed Notes registered on the relevant record date. On and after the redemption date, interest shall cease to accrue on Notes or portions thereof called for redemption.

-51-

SECTION 3.4 Notice of Redemption.

(a)At least 10 days but not more than 60 days before a date for redemption of Notes, the Issuer will mail a notice of redemption by first-class mail (or otherwise deliver in accordance with the applicable procedures of the Depositary) to each Holder of Notes to be redeemed at such Holder’s registered address, except that redemption notices may be sent (or otherwise delivered in accordance with the applicable procedures of the Depositary) more than 60 days prior to the redemption date if the notice is issued in connection with a defeasance of the Notes or a satisfaction and discharge of this Indenture. Any inadvertent defect in the notice of redemption, including an inadvertent failure to give notice, to any Holder selected for redemption shall not impair or affect the validity of the redemption of any other Note redeemed in accordance with the provisions of this Indenture. This Section 3.4(a) shall not apply to any Special Mandatory Redemption pursuant to Section 3.9.

(b)Any notice of redemption pursuant to Section 3.4(a) or Section 3.9 shall identify the Notes to be redeemed and shall state:

(i)the redemption date;

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

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

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

(v)solely in the case of a redemption pursuant to Section 3.4(a) (and not pursuant to Section 3.9), if fewer than all the outstanding Notes are to be redeemed (and if other than on a pro rata basis), the identification numbers and principal amounts (which amounts may be stated as a ratio of the amount to be redeemed per $1,000 principal amount outstanding) of the particular Notes to be redeemed;

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

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

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

(ix)solely in the case of a redemption pursuant to Section 3.4(a) (and not pursuant to Section 3.9), the conditions precedent, if any, applicable to such redemption. If such redemption or notice is subject to satisfaction of one or more

-52-

conditions precedent, such notice shall state that, in the Issuer’s discretion, the redemption date may be delayed until such time as any or all of such conditions shall be satisfied (or waived by the Issuer in its sole discretion), or such redemption may not occur and such notice may be rescinded in the event that any or all such conditions shall not have been satisfied (or waived by the Issuer in its sole discretion) by the redemption date, or by the redemption date so delayed.

(c)At the Issuer’s request, upon written notice provided to the Trustee at least 3 days (unless a shorter period is satisfactory to the Trustee) prior to the date the redemption notice must be given to the Holders (provided no such notice shall be required for a redemption in accordance with Section 3.9), the Trustee shall give the notice of redemption in the Issuer’s name and at the Issuer’s expense. In such event, the Issuer will provide the Trustee with the information required by this Section 3.4 and Section 3.9, as applicable, and a copy of the proposed notice of redemption to be sent to the Holders.

(d)Any redemption notice pursuant to Section 3.4(a) (but not Section 3.9) may, at the Issuer’s discretion, be subject to one or more conditions precedent, including completion of a Qualified Equity Offering, refinancing transaction or other corporate transaction. If any condition precedent has not been satisfied, the Issuer will provide written notice to the Trustee prior to the close of business on the Business Day prior to the redemption date. Upon receipt of such notice, the notice of redemption shall be rescinded and the redemption of the Notes shall not occur or, if specified in such notice, the date of such redemption shall be extended to the specified date, which shall not be later than the latest date upon which such redemption is permitted to occur under this Article 3. Upon receipt, the Trustee shall provide such notice to each Holder of the Notes in the same manner in which the notice of redemption was given.

SECTION 3.5 Tax Redemption. The Notes may be redeemed, at the option of the Issuer, in whole but not in part, at any time upon giving not less than 15 nor more than 60 days’ written notice to the Holders (which notice shall be irrevocable) in accordance with Section 3.4 hereof, at a redemption price equal to 100% of the principal amount thereof on the date of redemption, plus accrued and unpaid interest, if any, to but not including the date of redemption (subject to the right of Holders of record on the relevant record date to receive interest due on the relevant interest payment date) in the event the Issuer, the Company or any Subsidiary 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 (1) a change in or an amendment to the laws (including any regulations promulgated thereunder) of a Relevant Taxing Jurisdiction (or any political subdivision or taxing authority thereof or therein) or the official entry or any change in the official application or interpretation of such laws or regulations; or (2) any change in or amendment to any official position regarding the application or interpretation of such laws or regulations, which change or amendment is announced or becomes effective on or after the Issue Date (or, if the Relevant Taxing Jurisdiction has changed since the Issue Date, the date on which such jurisdiction became a Relevant Taxing Jurisdiction) and it cannot avoid such obligation by taking reasonable measures available to it. Before the Issuer delivers notice of redemption of the Notes as described above, it will deliver to the Trustee an Officer’s Certificate to the effect that it cannot avoid its obligation to pay Additional Amounts by taking reasonable measures available to it.

(c)For the purpose of this Section 4.4:

(1)Guarantees of, or obligations in respect of letters of credit relating to, Indebtedness that is otherwise included in the determination of a particular amount of Indebtedness shall not be included;

-57-

(2)if obligations in respect of letters of credit are Incurred pursuant to a credit agreement and are being treated as Incurred under clause (1) or (17) of the definition of Permitted Liens and the letters of credit relate to other Indebtedness, then such other Indebtedness shall not be included;

(3)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 GAAP;

(4)accrual of interest, accrual of dividends, the accretion of accreted value or original issue discount, the amortization of debt discount and the payment of interest in the form of additional indebtedness will not be deemed to be an Incurrence of the Indebtedness secured by the relevant Lien, and the amount of any Indebtedness secured by the relevant Lien outstanding as of any date shall be the accreted value thereof in the case of any Indebtedness issued with original issue discount or the aggregate principal amount outstanding in the case of Indebtedness issued with interest payable in kind and (ii) the principal amount or liquidation preference thereof, together with any interest thereon that is more than 30 days past due, in the case of any other Indebtedness;

penalties or premiums (including reasonable tender premiums), defeasance and satisfaction and discharge costs, accrued interest and other costs and expenses incurred in connection with such refinancing will not be deemed to be an Incurrence of Indebtedness secured by such Liens;

(1)the Company, the Issuer or such Restricted Subsidiary would be entitled to create a Lien on such Principal Property securing an amount at least equal to the Attributable Debt with respect to such arrangement, without equally and ratably securing (or securing on a senior basis, as applicable) the Notes or the Note Guarantees pursuant to Section 4.4; or

(c)Notwithstanding the foregoing, the Company, the Issuer and the Restricted Subsidiaries may enter into a Sale and Leaseback Transaction in addition to those permitted above, provided, however, that after giving effect thereto, Exempted Debt does not exceed 10% of Consolidated Total Assets of the Company measured as of the date of Incurrence of any Exempted Debt.

(d)For the purpose of this Section 4.5:

(1)in determining compliance with any U.S. dollar-denominated restriction on the entering into of any Sale and Leaseback Transaction, the U.S. dollar-equivalent principal amount of Attributable Debt denominated in a foreign currency shall be calculated based upon the relevant currency exchange rate in effect on the date such Attributable Debt was Incurred in respect of such Sale and Leaseback Transaction; and

(5)default under any mortgage, indenture or instrument under which there is issued or by which there is secured or evidenced any Indebtedness for money borrowed by the Company, the Issuer or any Restricted Subsidiary (or the payment of which is Guaranteed by the Company, the Issuer or any Restricted Subsidiary), whether such Indebtedness or Guarantee now exists, or is created after the Issue Date, which default:

(A)is caused by a failure to pay principal on such Indebtedness at its Stated Maturity (after giving effect to any applicable grace period provided in such Indebtedness) (“payment default”); or

(B)results in the acceleration of such Indebtedness prior to its maturity (the “cross acceleration provision”);

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 and remains unpaid, aggregates $250 million or more (or its

-66-

foreign currency equivalent) (it being understood, for the avoidance of doubt, that Indebtedness owed to the Company, the Issuer or any Restricted Subsidiary shall not constitute Indebtedness for the purposes of this clause (5));

(6)failure by the Company, the Issuer or any Significant Subsidiary or any group of Restricted Subsidiaries that, taken together (as of the date of the latest consolidated financial statements of the Company made available to the Holders), would constitute a Significant Subsidiary to pay final judgments aggregating in excess of $250 million (or its foreign currency equivalent) (net of any amounts covered by a reputable and creditworthy insurance company), which judgments are not paid, discharged or stayed for a period of 90 days or more after such judgment becomes final and non-appealable (the “judgment default provision”);

(7)(A) the Company, the Issuer or a Significant Subsidiary or any group of Restricted Subsidiaries that, taken together (as of the date of the latest consolidated financial statements of the Company made available to the Holders), would constitute a Significant Subsidiary, pursuant to or within the meaning of any Bankruptcy Law:

(i)commences a voluntary case;

(ii)consents to the entry of an order for relief against it in an involuntary case or the filing by it of a petition or answer or consent seeking an arrangement of debt, reorganization, dissolution, winding up or relief under applicable Bankruptcy Law;

(iv)makes a general assignment for the benefit of its creditors;

or takes any comparable action under any foreign laws relating to insolvency; or

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

(i)is for relief against the Company, the Issuer or a Significant Subsidiary or any group of Restricted Subsidiaries that, taken together (as of the date of the latest consolidated financial statements of the Company made available to the Holders), would constitute a Significant Subsidiary, in an involuntary case;

(ii)appoints a Bankruptcy Custodian of the Company, the Issuer or a Significant Subsidiary or any group of Restricted Subsidiaries that, taken together (as of the date of the latest consolidated financial statements of the Company

-67-

made available to the Holders), would constitute a Significant Subsidiary, or for any substantial part of the property of any of the foregoing; or

(iii)orders the winding up or liquidation of the Company, the Issuer or a Significant Subsidiary or any group of Restricted Subsidiaries that, taken together (as of the date of the latest consolidated financial statements of the Company made available to the Holders), would constitute a Significant Subsidiary;

(8)the Note Guarantee of the Company, or any Note Guarantee of a Significant Subsidiary or any group of Subsidiary Guarantors that, taken together (as of the date of the latest consolidated financial statements of the Company made available to the Holders), would constitute a Significant Subsidiary, ceases to be in full force and effect (except as contemplated by the terms of this Indenture) or is declared null and void in a final and non-appealable judicial proceeding or a responsible officer of the Company or any Subsidiary Guarantor that is a Significant Subsidiary or the responsible officers of any group of Subsidiary Guarantors that, taken together (as of the date of the latest consolidated financial statements of the Company made available to the Holders), would constitute a Significant Subsidiary, denies or disaffirms in writing its obligations under this Indenture or its Note Guarantee, other than by reason of the termination of this Indenture or release of any such Note Guarantee in accordance with this Indenture.

The foregoing clauses shall constitute Events of Default whatever the reason for any such Event of Default and whether it is voluntary or involuntary or is effected by operation of law or pursuant to any judgment, decree or order of any court or any order, rule or regulation of any administrative or governmental body.

However, a default under Section 6.1(a)(4) or (6) will not constitute an Event of Default until the Trustee or the holders of 30% in principal amount of the Notes then outstanding notify the Company and the Issuer of the default and the Company and the Issuer do not cure such default within the time specified after receipt of such notice. Any default for the failure to deliver any report within the time periods prescribed in Section 4.2 or to deliver any notice or certificate pursuant to any other provision of this Indenture shall be deemed to be cured upon the subsequent delivery of any such report, notice or certificate, even though such delivery is not within the prescribed period specified.

The term “Bankruptcy Law” means any law relating to bankruptcy, insolvency, receivership, winding-up, liquidation, reorganization or relief of debtors or any amendment to, succession to or change in any such law, including, without limitation, the United States Bankruptcy Code, 11 United States Code §§ 101 et seq. The term “Bankruptcy Custodian” means any receiver, trustee, assignee, liquidator, custodian or similar official under any Bankruptcy Law.

-68-

The Company shall deliver to the Trustee, within 30 days after obtaining knowledge of the occurrence thereof, written notice in the form of an Officer’s Certificate of any Default, its status and what action the Company is taking or proposes to take with respect thereto.

SECTION 6.2 Acceleration. If an Event of Default occurs and is continuing with respect to the Notes, the Trustee (by written notice to the Company) or the holders of at least 30% in principal amount of the Notes then outstanding (by written notice to the Company and the Trustee) may declare the principal of and accrued but unpaid interest on all the Notes to be due and payable. Upon such a declaration, such principal and interest shall be due and payable immediately. If an Event of Default specified under Section 6.1(a)(7) occurs and is continuing, the principal of and interest on all the Notes will ipso facto become and be immediately due and payable without any declaration or other act on the part of the Trustee or any Holders. At any time after a declaration of acceleration has been made, but before a judgment or decree for payment of the money due has been obtained, the Holders of not less than a majority in aggregate principal amount of the Notes by notice to the Trustee may rescind and annul that declaration of acceleration and its consequences if the rescission and annulment would not conflict with any judgment or decree and if all existing Events of Default have been cured or waived except nonpayment of principal or interest that has become due solely because of acceleration. No such rescission shall affect any subsequent Default or impair any right consequent thereto.

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

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 in exercising any right or remedy accruing upon an Event of Default shall not impair the right or remedy or constitute a waiver of or acquiescence in the Event of Default. No remedy is exclusive of any other remedy. All available remedies are cumulative.

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

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

-69-

with such direction. Prior to taking any action hereunder, the Trustee shall be entitled to indemnification or security reasonably satisfactory to it against any loss, liability or expense caused by taking or not taking such action.

SECTION 6.6 Limitation on Suits.

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

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

(2)Holders of at least 30% in principal amount of the Notes then outstanding have requested the Trustee to pursue the remedy;

(3)such Holders have offered the Trustee security or indemnity satisfactory to it against any loss, liability or expense;

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

(5)Holders of a majority in principal amount of the Notes then outstanding have not given the Trustee a direction inconsistent with such request within such 60-day period.

(b)A Holder may not use this Indenture to prejudice the rights of another Holder or to obtain a preference or priority over another Holder, it being understood that the Trustee has no affirmative duty to ascertain whether or not any actions or forbearances by a Holder are unduly prejudicial to other Holders. In the event that the Definitive Registered Notes are not issued to any beneficial owner promptly after the Registrar has received a request from the Holder of a Global Note to issue such Definitive Registered Notes to such beneficial owner of its nominee, the Issuer expressly agrees and acknowledges, with respect to the right of any Holder to pursue a remedy pursuant to this Indenture, the right of such beneficial holder of Notes to pursue such remedy with respect to the portion of the Global Note that represents such beneficial holder’s Notes as if such Definitive Registered Notes had been issued.

SECTION 6.7 Rights of Holders to Receive Payment. Notwithstanding any other provision of this Indenture, the contractual right of a Holder to bring suit for the payment of principal, interest or premium (if any) on the Notes held by such Holder, on or after the respective due dates, shall not be modified without the consent of such Holder.

SECTION 6.8 Collection Suit by Trustee. If an Event of Default specified in Section 6.1(a)(1) or (2) occurs and is continuing, the Trustee may recover judgment in its own name and as trustee of an express trust against the Issuer or any other obligor on the Notes for the whole amount then due and owing (together with interest on overdue principal and (to the extent lawful) on any unpaid interest at the rate provided for in the Notes) and the amounts provided for in Section 7.6.

-70-

SECTION 6.9 Trustee May File Proofs of Claim. The Trustee may file such proofs of claim and other papers or documents and take such other actions, including participating as members, voting or otherwise, of any committee of creditors appointed in the matter, as may be necessary or advisable in order to have the claims of the Trustee (including any claim for the reasonable compensation, expenses, disbursements and advances of the Trustee, and its agents and counsel) and the Holders allowed in any judicial proceedings relative to the Company, the Issuer or any Subsidiary Guarantor, their creditors or their property and, unless prohibited by law or applicable regulations, may vote on behalf of the Holders in any election of a trustee in bankruptcy or other Person performing similar functions, and any custodian in any such judicial proceeding is hereby authorized by each Holder to make payments to the Trustee and, in the event that the Trustee shall consent to the making of such payments directly to the Holders, to first pay to the Trustee any amount due 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 7.6.

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

FIRST: to the Trustee, its agents and attorneys, for amounts due under Section 7.6;

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

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

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

SECTION 6.11 Undertaking for Costs. In any suit for the enforcement of any right or remedy under this Indenture or in any suit against the Trustee for any action taken or omitted by it as Trustee, a court in its discretion may require the filing by any party litigant in the suit of an undertaking to pay the costs of the suit, and the court in its discretion may assess reasonable costs, including reasonable attorneys’ fees and expenses, against any party litigant in the suit, having due regard to the merits and good faith of the claims or defenses made by the party litigant. This Section 6.11 does not apply to a suit by the Issuer, a suit by the Trustee, a suit by a Holder pursuant to Section 6.7 or a suit by Holders of more than 10.0% in aggregate principal amount of the then outstanding Notes.

SECTION 6.12 Waiver of Stay or Extension Laws. The Issuer and each Guarantor agrees (to the extent it may lawfully do so) that it shall not at any time insist upon, or plead, or in any manner whatsoever claim or take the benefit or advantage of, any stay or

-71-

extension law wherever enacted, now or at any time hereafter in force, which may affect the covenants or the performance of this Indenture; and the Issuer and each Guarantor (to the extent that it may lawfully do so) hereby expressly waives all benefit or advantage of any such law, and shall not hinder, delay or impede the execution of any power herein granted to the Trustee, but shall suffer and permit the execution of every such power as though no such law had been enacted.

ARTICLE 7.

TRUSTEE

SECTION 7.1 Duties of Trustee.

(a)If an Event of Default has occurred and is continuing, the Trustee shall exercise the rights and powers vested in it by this Indenture and use the same degree of care and skill in its exercise as a prudent Person would exercise or use under the circumstances in the conduct of such Person’s own affairs.

(b)Except during the continuance of an Event of Default:

(i)the Trustee undertakes to perform such duties and only such duties as are specifically set forth in this Indenture and the Trustee shall not be liable except for the performance of such duties, and no implied covenants or obligations shall be read into this Indenture against the Trustee; and

However, in the case of any such certificates or opinions which by any provision hereof are specifically required to be furnished to the Trustee, the Trustee shall be under a duty to examine the same to determine whether or not they conform on their face to the requirements of this Indenture (but need not confirm or investigate the accuracy of mathematical calculations or other facts stated therein). The Trustee may (but shall in no way be obligated to) make further inquiry or investigation into such facts or materials as it sees fit.

(c)The Trustee may not be relieved from liability for its own negligent action, its own negligent failure to act, or bad faith or its own willful misconduct, except that:

-72-

(g)Every provision of this Indenture relating to the conduct or affecting the liability of or affording protection to the Trustee shall be subject to the provisions of Article 7.

SECTION 7.2 Rights of Trustee.

(b)Before the Trustee acts or refrains from acting, it may require an Officer’s Certificate or an Opinion of Counsel or both conforming to Section 11.3. The Trustee shall not be liable for any action it takes or omits to take in good faith in conclusive reliance on the Officer’s Certificate or Opinion of Counsel.

(c)The Trustee may act through attorneys and agents and shall not be responsible for the misconduct or negligence of any agent appointed with due care.

(d)The Trustee shall not be liable for any action it takes or omits to take in good faith which it believes to be authorized or within its rights or powers; provided, however, that the Trustee’s conduct does not constitute bad faith, willful misconduct or negligence.

-73-

(f)The Trustee shall not be required to give any bond or surety in respect of the performance of its powers and duties hereunder.

(g)The Trustee shall not be bound to ascertain or inquire as to the performance or observance of any covenants, conditions, or agreements on the part of the Issuer, but the Trustee may require of the Issuer full information and advice as to the performance of the covenants, conditions and agreements contained herein.

(h)The permissive rights of the Trustee to do things enumerated in this Indenture shall not be construed as a duty.

(i)The Trustee shall not be deemed to have notice or be charged with knowledge of any Default or Event of Default unless a Trust Officer of the Trustee has received from the Issuer or the Holders of not less than 30% in aggregate principal amount of the Notes then outstanding written notice thereof at the Corporate Trust Office of the Trustee, and such notice references the Notes and this Indenture.

(j)The rights, privileges, protections, immunities and benefits given to the Trustee, including, without limitation, its right to be indemnified, are extended to, and shall be enforceable by, the Trustee and each other agent, custodian and Person employed to act hereunder.

(k)In no event shall the Trustee be responsible or liable for special, indirect, punitive, incidental or consequential loss or damage of any kind whatsoever (including, but not limited to, loss of profit) irrespective of whether the Trustee has been advised of the likelihood of such loss or damage and regardless of the form of action.

(l)Any request or direction of the Issuer or other Person mentioned herein shall be sufficiently evidenced by an Officer’s Certificate or certificate of an Officer of such other Person and any resolution of the Board of Directors of the Issuer or of such other Person may be sufficiently evidenced by a board resolution certified by the secretary or assistant secretary (or similar officer) of such Person.

(m)The Trustee may request that the Issuer deliver a 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 certificate may be updated and delivered to the Trustee at any time by the Issuer in its discretion.

(o)No provision of this Indenture shall be deemed to impose any duty or obligation on the Trustee to take or omit to take any action, or suffer any action to be taken or omitted, in the performance of its duties or obligations under this Indenture, or to exercise any

-74-

right or power thereunder, to the extent that taking or omitting to take such action or suffering such action to be taken or omitted would violate applicable law binding upon it.

(p)The delivery of reports, information and documents to the Trustee is for informational purposes only, and the Trustee’s receipt of such shall not constitute actual or constructive notice or knowledge of any information contained therein or determinable from information contained therein, including the Issuer’s compliance with any of its covenants under this Indenture (as to which the Trustee is entitled to rely exclusively on Officer’s Certificates).

SECTION 7.3 Individual Rights of the 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 its Affiliates with the same rights it would have if it were not Trustee; and any Paying Agent, Registrar or any other agent of the Trustee may do the same with like rights; provided, however, that if any of them acquire any “conflicting interest” (within the meaning of Section 310(b) of the Trust Indenture Act), they must eliminate such conflict within 90 days or resign in accordance with the terms of this Indenture.

SECTION 7.4 Trustee’s Disclaimer. The Trustee shall not be responsible for and makes no representation as to the validity or adequacy of this Indenture or the Notes, it shall not be accountable for the Issuer’s use of the proceeds from the Notes, and it shall not be responsible for any statement of the Issuer or any other Person in this Indenture or in any document issued in connection with the sale of the Notes or in the Notes other than the Trustee’s certificate of authentication.

SECTION 7.5 Notice of Defaults. If a Default occurs and is continuing and a Trust Officer shall have received written notice thereof at its Corporate Trust Office and such notice references the Notes and this Indenture, the Trustee shall send to each Holder a notice of the Default within 90 days after it occurs. Except in the case of a Default specified in Sections 6.1(a)(1) or (2), the Trustee may withhold from Holders notice of any continuing Default if a committee of its Trust Officers determines in good faith that withholding the notice is not opposed to the interests of such Holders.

SECTION 7.6 Compensation and Indemnity.

(a)The Issuer and the Guarantors, jointly and severally, shall pay to the Trustee from time to time such compensation for its services as shall be agreed to in writing from time to time by the Issuer, the Guarantors and the Trustee. The Trustee’s compensation shall not be limited by any law on compensation of a trustee of an express trust. The Issuer shall reimburse the Trustee upon request for all reasonable out-of-pocket expenses incurred or made by it, including costs of collection, in addition to the compensation for its services. Such expenses shall include the reasonable compensation and expenses, disbursements and advances of the Trustee’s agents, counsel, accountants and experts. The Issuer and the Guarantors, jointly and severally, shall indemnify the Trustee, its agents, representatives, officers, directors, employees and attorneys against any and all loss, liability, damage, claim (whether asserted by the Issuer, a Guarantor, a Holder or any other person) or expense (including reasonable compensation and expenses and disbursements of the Trustee’s counsel) arising out of or in connection with the administration of this trust and the performance of its duties, or in

-75-

connection with the enforcement of any rights hereunder, or arising out of or in connection with the exercise or performance of any of its rights or powers hereunder. The Trustee shall notify the Issuer promptly of any claim for which it may seek indemnity. Failure by the Trustee to so notify the Issuer shall not relieve the Issuer or the Guarantors of their obligations hereunder. The Issuer shall defend the claim and the Trustee shall provide reasonable cooperation in such defense. The Issuer shall pay the reasonable fees and expenses of counsel to the Trustee reasonably acceptable to the Issuer; provided, however, that the Issuer shall not be required to pay such fees and expenses if the Issuer assumes such defense unless there is a conflict of interest between the Issuer and the Trustee in connection with such defense as determined by the Trustee in consultation with counsel or if there are additional or separate defenses available to the Trustee that are not available to the Issuer and the Issuer is unable to assert any such defense on the Trustee’s behalf. Notwithstanding the foregoing, the Issuer need not reimburse any expense or indemnify against any loss, liability, damage, claim or expense incurred by the Trustee through its own willful misconduct, bad faith or negligence.

(b)To secure the payment obligations of the Issuer and the Guarantors in this Section 7.6 the Trustee shall have a Lien prior to the Notes on all money or property held or collected by the Trustee, in its capacity as Trustee, other than money or property held in trust to pay principal of and interest, if any, on particular Notes.

(c)The Issuer’s payment obligations pursuant to this Section 7.6 shall survive the resignation or removal of the Trustee and the discharge of this Indenture. When the Trustee incurs expenses after the occurrence of a Default specified in Section 6.1(a)(7) with respect to the Issuer, the expenses are intended to constitute expenses of administration under the Bankruptcy Law.

SECTION 7.7 Replacement of Trustee.

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

(i)the Trustee is no longer eligible under Section 7.9;

(ii)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;

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

(iv)the Trustee otherwise becomes incapable of acting.

(b)If, with respect to the Notes, the Trustee resigns or has been removed by the Holders, Holders of a majority in principal amount of the outstanding Notes may appoint a successor Trustee with respect to the Notes. Otherwise, if the Trustee resigns or is removed (and

-76-

such Holders do not reasonably promptly appoint a successor Trustee), or if a vacancy exists in the office of Trustee for any reason, the Issuer shall promptly appoint a successor Trustee. Within one year after the successor Trustee takes office, the Holders of a majority in aggregate principal amount of the then outstanding Notes may remove the successor Trustee to replace it with another successor Trustee appointed by the Issuer.

(c)A successor Trustee shall deliver a written acceptance of its appointment to the retiring Trustee and to the Issuer. Thereupon the resignation or removal of the retiring Trustee shall become effective, and the successor Trustee shall have all the rights, powers and duties of the Trustee under this Indenture. The successor Trustee shall send a notice of its succession to Holders of the Notes, and include in the notice its name and address of its corporate trust office. The retiring Trustee shall promptly transfer all property held by it as Trustee to the successor Trustee, subject to the Lien provided for in Section 7.6.

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

(e)If the Trustee fails to comply with Section 7.9, any Holder may petition any court of competent jurisdiction for the removal of the Trustee and the appointment of a successor Trustee with respect to the Notes.

(f)Notwithstanding the replacement of the Trustee pursuant to this Section 7.7, the Issuer’s obligations under Section 7.6 shall continue for the benefit of the retiring Trustee.

SECTION 7.8 Successor Trustee by Merger.

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

(b)In case at the time such successor or successors by merger, conversion or consolidation to shall succeed to the trusts created by this Indenture, any of the Notes shall have been authenticated but not delivered, any such successor to the Trustee may adopt the certificate of authentication of any applicable predecessor Trustee, and deliver such Notes so authenticated; and in case at that time any of the Notes shall not have been authenticated, any successor to the Trustee may authenticate such Notes either in the name of any predecessor hereunder or in the name of the successor to the Trustee; and in all such cases such certificates shall have the full force which the Notes provide or this Indenture provides that the certificate of the Trustee shall have.

SECTION 7.9 Eligibility; Disqualification.

(a)There shall at all times be one or more Trustees under this Indenture, each of which (1) is a corporation organized and doing business under the laws of the United States or

-77-

of any state or of the District of Columbia or a corporation or other person permitted to act as trustee by the SEC, (2) is authorized under such laws to exercise corporate trust powers, and (3) is subject to supervision or examination by federal, state, or District of Columbia authorities.

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

SECTION 7.10 Multiple Trustees.

(a)Notwithstanding anything to the contrary herein, any successor Trustee may be appointed with respect to the Notes; provided, however, that at any one time there shall be only one Trustee with respect to the Notes.

(b)In case of the appointment hereunder of a successor Trustee with respect to the Notes, every such successor Trustee so appointed shall execute, acknowledge and deliver to the Issuer and to the retiring Trustee an instrument accepting such appointment, and thereupon the resignation or removal of the retiring Trustee shall become effective and such successor Trustee, without any further act, deed or conveyance, shall become vested with all the rights, powers, trusts and duties of the retiring Trustee; but, on the request of the Issuer or the successor Trustee, such retiring Trustee shall, upon payment of its reasonable charges, if any, execute and deliver an instrument transferring to such successor Trustee all the rights, powers and trusts of the retiring Trustee and shall duly assign, transfer and deliver to such successor Trustee all property and money held by such retiring Trustee hereunder; subject, nevertheless, to its lien provided for in Section 7.6.

(c)Upon request of any such successor Trustee, the Issuer shall execute any and all instruments for more fully and certainly vesting in and confirming to such successor Trustee all such rights, powers and trusts referred to in Section 7.10(b). No successor Trustee with respect to the Notes shall accept its appointment unless at the time of such acceptance such successor Trustee shall be qualified and eligible with respect to the Notes under this Article.

SECTION 7.11 Limitation on Trustee’s Liability. Except as provided in this Article 7, in accepting the trusts hereby created, the entity acting as Trustee is not acting in its individual capacity and, except as provided in this Article 7, all Persons having any claim against the Trustee by reason of the transactions contemplated by this Indenture or any Note shall look only to the Issuer or a Guarantor for payment or satisfaction thereof.

ARTICLE 8.

DISCHARGE OF INDENTURE; DEFEASANCE

SECTION 8.1 Discharge of Liability On Notes; Defeasance.

(a)When (i) the Issuer delivers to the Trustee all outstanding Notes that have been authenticated (other than lost, stolen or destroyed Notes replaced or paid pursuant to the terms of this Indenture and Notes for which payment money has been deposited in trust and thereafter repaid to the Issuer) for cancellation or (ii) (A) all outstanding Notes not previously delivered to the Trustee for cancellation have become due and payable by reason of maturity, the giving of a notice of redemption or otherwise, will become due and payable within one year or

-78-

may be called for redemption within one year under arrangements satisfactory to the Trustee for the giving of notice of redemption by the Trustee in the Issuer’s name and at the Issuer’s expense, and the Issuer has irrevocably deposited or caused to be deposited with the Trustee, as trust funds in trust solely for the benefit of the Holders, cash, U.S. Government Obligations, or a combination thereof, in such amounts as will be sufficient, in the opinion of a nationally recognized firm of independent public accountants, without consideration of any reinvestment of interest, to pay and discharge the entire Indebtedness on the Notes not theretofore delivered to the Trustee for cancellation for principal, premium, if any, and accrued interest to the date of maturity or redemption; (B) the Issuer has paid or caused to be paid all sums payable by it under this Indenture with respect to the Notes; and (C) the Issuer has delivered irrevocable instructions to the Trustee to apply the deposited money toward the payment of the Notes at maturity or the redemption date, as the case may be, then, this Indenture and all of the Issuer’s obligations in respect of the Notes shall, subject to Section 8.1(c), cease to be of further effect, and the Issuer shall be deemed to have satisfied and discharged this Indenture and all of its obligations in respect of the Notes. The Trustee shall acknowledge satisfaction and discharge of this Indenture on demand of the Issuer accompanied by an Officer’s Certificate and an Opinion of Counsel and at the cost and expense of the Issuer. For the avoidance of doubt, the Issuer will continue to be obligated to pay all other sums due under this Indenture to the Trustee.

(b)Subject to Sections 8.1(c) and 8.2, the Issuer at any time may terminate (i) all its obligations under the Notes and this Indenture (“legal defeasance option”) or (ii) its obligations with respect to the Notes under Article 4 (with the exception of Sections 4.1 and 4.3) and the operation of Section 6.1(a)(5)(B), Section 6.1(a)(6) and, with respect to Significant Subsidiaries and Subsidiary Guarantors, Section 6.1(a)(7) (“covenant defeasance option”). The Issuer may exercise its legal defeasance option with respect to the Notes notwithstanding its prior exercise of its covenant defeasance option with respect thereto. If the Issuer exercises its legal defeasance option with respect to the Notes, payment of the Notes may not be accelerated because of an Event of Default with respect to the Notes. If the Issuer exercises its covenant defeasance option with respect to the Notes, payment of the Notes may not be accelerated because of an Event of Default specified in Sections 6.1(a) (3), (4), (5), (6), (7) (with respect to Significant Subsidiaries) or (8). If the Issuer exercises its legal defeasance option or its covenant defeasance option with respect to the Notes, each Subsidiary Guarantor shall be released from all its obligations with respect to its Note Guarantee. Upon satisfaction of the conditions set forth herein and upon request of the Issuer, the Trustee shall acknowledge in writing the discharge of those obligations that the Issuer terminates.

(c)Notwithstanding clauses (a) and (b) above with respect to the Notes, the Issuer’s rights and obligations in Sections 2.3, 2.4, 2.5, 2.6, 2.8, 2.9, 2.10, 2.11, 2.12, 7.6, 7.7 and this Article 8 with respect to the Notes shall survive until the Notes have been paid in full, and, thereafter, the Issuer’s rights and obligations in Sections 7.6 and 8.4 shall survive.

SECTION 8.2 Conditions to Defeasance.

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

(i)the Issuer irrevocably deposits in trust (the “defeasance trust”) with the Trustee money or U.S. Government Obligations or a combination thereof (sufficient in the opinion of a nationally recognized certified public accounting

-79-

firm) for the payment of principal and interest on the Notes to redemption or maturity;

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

(iii)no Default or Event of Default under this Indenture has occurred and is continuing after giving effect to such defeasance or covenant defeasance (other than a Default or Event of Default resulting from the borrowing of funds to be applied to such deposit and any simultaneous deposit relating to other indebtedness and, in each case, the granting of Liens in connection therewith);

(iv)the Issuer is not an insolvent, unable to pay its debts in full or on the eve of insolvency under applicable law on the date of such deposit;

(v)the Issuer shall have delivered to the Trustee an Opinion of Counsel to the effect that Holders and beneficial owners of the Notes will not recognize income, gain or loss for Federal income tax purposes as a result of such deposit and defeasance and will be subject to Federal income tax on the same amounts and in the same manner and at the same times as would have been the case if such deposit and defeasance had not occurred (and, in the case of legal defeasance only, such Opinion of Counsel shall be based on a ruling of the Internal Revenue Service or other change in applicable Federal income tax law);

(vi)the Issuer shall have delivered to the Trustee an Opinion of Counsel in the jurisdiction of organization of the Issuer to the effect that Holders and beneficial owners of the Notes will not recognize income, gain or loss for income tax purposes of such jurisdiction as a result of such deposit and defeasance and will be subject to income tax of such jurisdiction on the same amounts and in the same manner and at the same times as would have been the case if such deposit and defeasance had not occurred; and

(vii)the Issuer delivers to the Trustee an Officer’s Certificate and an Opinion of Counsel, each to the effect that all conditions precedent to such defeasance or defeasance as contemplated by this Article 8 have been complied with.

(b)In connection with any defeasance or covenant defeasance involving a redemption that requires the payment of the Applicable Premium, the amount deposited with the Trustee as provided in Section 8.2(a)(i) in respect of such Applicable Premium shall be sufficient if equal to the Applicable Premium calculated as of the date of deposit, with any deficit as of the date of redemption (any such amount, the “Applicable Premium Deficit”) only required to be

-80-

deposited with the Trustee on or prior to the date of redemption. Any Applicable Premium Deficit shall be set forth in an Officer’s Certificate delivered to the Trustee simultaneously with the deposit of such Applicable Premium Deficit that confirms that such Applicable Premium Deficit shall be applied toward such redemption.

SECTION 8.3 Application of Trust Money. The Trustee shall hold in trust money or U.S. Government Obligations deposited with it pursuant to this Article 8. It shall apply the deposited money and the money from U.S. Government Obligations through the Paying Agent and in accordance with this Indenture to the payment of principal of, interest (if any) and Additional Amounts (if any) on the Notes.

SECTION 8.4 Repayment to the Issuer. The Trustee and the Paying Agent shall promptly turn over to the Issuer upon request any money or U.S. Government Obligations held by it as provided in this Article which, in the written opinion of a nationally recognized firm of independent public accountants delivered to the Trustee (which delivery shall only be required if U.S. Government Obligations have been so deposited), are in excess of the amount thereof which would then be required to be deposited to effect an equivalent discharge or defeasance in accordance with this Article.

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

SECTION 8.5 Reinstatement. If the Trustee or Paying Agent is unable to apply any money or U.S. Government Obligations in accordance with this Article 8 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 obligations under this Indenture and the Notes shall be revived and reinstated as though no deposit had occurred pursuant to this Article 8 until such time as the Trustee or Paying Agent is permitted to apply all such money or U.S. Government Obligations in accordance with this Article 8; provided, however, that, if the Issuer has made any payment of interest on or principal of any Notes because of the reinstatement of its obligations, the Issuer shall be subrogated to the rights of the Holders of such Notes to receive such payment from the money or U.S. Government Obligations held by the Trustee or Paying Agent.

ARTICLE 9.

SECTION 9.1 Without Consent of Holders.

(a)The Issuer, the Guarantors and the Trustee may enter into supplemental indentures that amend, waive or supplement the terms of this Indenture, the Notes or the Subsidiary Guarantees without notice to or consent of any Holder for the following specific purposes:

(9)to make any amendment to the provisions of this Indenture relating to the transfer and legending of Notes; provided, however, that (A) compliance with this Indenture as so amended would not result in Notes being transferred in violation of the Securities Act or any other applicable securities law and (B) such amendment does not materially and adversely affect the rights of Holders to transfer Notes except as required to satisfy any applicable requirements of the securities laws, including any exemption from registration thereunder;

(10)to evidence and provide for the acceptance and appointment under this Indenture of a successor Trustee thereunder pursuant to the requirements thereof; and

(11)to provide for the issuance of Additional Notes in accordance with the terms of this Indenture.

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

-82-

SECTION 9.2 With Consent of Holders; Waiver.

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

(1)reduce the amount of Notes whose Holders must consent to an amendment;

(2)reduce the rate of or extend the time for payment of interest on any Note;

(3)reduce the principal of or change the Stated Maturity of any Note;

(8)make any change in the ranking or priority of any Note or Note Guarantee that would adversely affect the Holders; or

(9)make any change in the provisions of Section 2.13 that adversely affects the rights of any Holder.

(b)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, but it shall be sufficient if such consent approves the substance thereof. For the avoidance of doubt, no amendment to, or deletion of any of the covenants contained in Article 4 (other than Section 4.1) shall be deemed to impair or affect any rights of Holders to institute suit for the enforcement of any payment on or with respect to, or to receive payment of principal of, or premium, if any, or interest on, the Notes.

-83-

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

SECTION 9.3 Revocation and Effect of Consents and Waivers.

(a)A consent to an amendment or a waiver by a Holder shall bind the Holder and every subsequent Holder of that Note or portion of the Note that evidences the same debt as the consenting Holder’s Note, even if notation of the consent or waiver is not made on the Note. However, any such Holder or subsequent Holder may revoke the consent or waiver as to such Holder’s Note or portion of the Note if the Trustee receives written notice of revocation at the Corporate Trust Office of the Trustee before the date the amendment or waiver becomes effective. After an amendment or waiver becomes effective, it shall bind every Holder. An amendment or waiver becomes effective upon the (i) receipt by the Issuer or the Trustee of the requisite number of consents, (ii) satisfaction of the conditions to effectiveness as set forth in this Indenture and any indenture supplemental hereto containing such amendment or waiver and (iii) execution of such amendment or waiver (or Guarantee Agreement) by the Issuer, the Company and the Trustee.

(b)The Issuer may, but shall not be obligated to, fix a record date for the purpose of determining the Holders entitled to give their consent or take any other action described above or required or permitted to be taken pursuant to this Indenture. If a record date is fixed, then notwithstanding the immediately preceding paragraph, those Persons who were Holders at such record date (or their duly designated proxies), and only those Persons, shall be entitled to give such consent or to revoke any consent previously given or to take any such action, whether or not such Persons continue to be Holders after such record date. No such consent shall be valid or effective for more than 90 days after such record date.

SECTION 9.4 Notation on or Exchange of Notes.

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

SECTION 9.5 Trustee To Sign Amendments, etc.

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

ARTICLE 10.

GUARANTEES

SECTION 10.1 Guarantees.

(a)The Company and each Subsidiary Guarantor hereby jointly and severally irrevocably and unconditionally guarantees to each Holder and to the Trustee and their respective successors and assigns (i) the full and punctual payment when due, whether at Stated Maturity, by acceleration, by redemption or otherwise, of all obligations of the Issuer under this Indenture (including obligations to the Trustee) and the Notes, whether for payment of principal of, or interest on the Notes and all other monetary obligations of the Issuer under this Indenture and the Notes and (ii) the full and punctual performance within applicable grace periods of all other obligations of the Issuer whether for fees, expenses, indemnification or otherwise under this Indenture and the Notes (all the foregoing being hereinafter collectively called the “Guaranteed Obligations”). Each Guarantor further agrees that the Guaranteed Obligations may be extended or renewed, in whole or in part, to the fullest extent permitted under applicable law, without notice or further assent from each such Guarantor, and that each such Guarantor shall remain bound under this Article 10 notwithstanding any extension or renewal of any Guaranteed Obligation.

(b)To the fullest extent permitted by applicable law, each Guarantor waives presentation to, demand of payment from and protest to the Issuer of any of the Guaranteed Obligations, notice of protest for nonpayment and notice of any default under the Notes or the Guaranteed Obligations. To the fullest extent permitted by applicable law, the obligations of each Guarantor hereunder shall not be affected by (i) the failure of any Holder or the Trustee to assert any claim or demand or to enforce any right or remedy against the Issuer or any other Person under this Indenture, the Notes or any other agreement or otherwise, (ii) any extension or renewal of any thereof, (iii) any rescission, waiver, amendment or modification of any of the terms or provisions of this Indenture, the Notes or any other agreement, (iv) the failure of any Holder or Trustee to exercise any right or remedy against any other guarantor of the Guaranteed Obligations or (vi) any change in the ownership of such Guarantor.

(c)To the fullest extent permitted by applicable law, each Guarantor hereby waives any right to which it may be entitled (i) to have its obligations hereunder divided among the Guarantors, such that such Guarantor’s obligations would be less than the full amount claimed, (ii) to have the assets of the Issuer first be used and depleted as payment of the Issuer’s or such Guarantor’s obligations hereunder prior to any amounts being claimed from or paid by such Guarantor hereunder and (iii) to require that the Issuer be sued prior to an action being initiated against such Guarantor.

(d)Each Guarantor further agrees that its Guarantee herein constitutes a guarantee of payment, performance and compliance when due (and not a guarantee of collection) and waives any right to require that any resort be had by any Holder or the Trustee to any security held for payment of the Guaranteed Obligations.

-85-

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

Without limiting the generality of the foregoing, the obligations of each Guarantor herein shall not be discharged or impaired or otherwise affected by the failure of any Holder or the Trustee to assert any claim or demand or to enforce any remedy under this Indenture, the Notes or any other agreement, by any waiver or modification of any thereof, by any default, failure or delay, willful or otherwise, in the performance of the obligations, or by any other act or thing or omission or delay to do any other act or thing which may or might in any manner or to any extent vary the risk of any Guarantor or would otherwise operate as a discharge of any Guarantor as a matter of law or equity.

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

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

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

-86-

(i)Each Guarantor also agrees to pay any and all costs and expenses (including reasonable attorneys’ fees and expenses) incurred by the Trustee or any Holder in enforcing any rights under this Section 10.1.

(j)The obligations and liabilities of any guarantor incorporated in Norway in its capacity as a guarantor (each a “Norwegian Guarantor”) shall not cover any indebtedness or liability which, if they did so extend, would cause an infringement of Section 8-10 and/or Section 8-7 cf. Section 1-3, or any of the other provisions in chapter 8 III, of the Norwegian Private Limited Companies Act 1997 (the “Norwegian Companies Act” regulating unlawful financial assistance and other prohibited loans, guarantees and joint and several liability as well as providing of security, and it is understood and agreed that the liability of any Norwegian Guarantor only applies to the extent permitted by the above-mentioned provisions of the Norwegian Companies Act. Under no circumstances shall the obligations and liabilities of any Norwegian Guarantor cover the debt and/or other liabilities incurred in respect of the purchase of the shares in any of such Norwegian Guarantor’s Holding.

(k)For each Guarantor incorporated in Switzerland (a “Swiss Guarantor”):

(1)If and to the extent (x) the Guarantee under this Article 10 or any other indemnity by a Swiss Guarantor under this Indenture or the Notes guarantees or indemnifies obligations of its (direct or indirect) parent companies (upstream security) or sister companies (cross-stream security) (the “Upstream or Cross-Stream Guaranteed Obligations”) and (y) using payments under this Indenture or the Notes to discharge the Upstream or Cross-Stream Guaranteed Obligations would constitute a repayment of capital (Einlagerückgewähr/Kapitalrückzahlung), a violation of the legally protected reserves (gesetzlich geschützte Reserven) or the payment of a (constructive) dividend (Gewinnausschüttung) under Swiss corporate law, the payments under this Indenture and the Notes shall be limited to the maximum amount of the Swiss Guarantor’s freely disposable shareholder equity at the time of enforcement (the “Maximum Amount”); provided that such limitation is required under the applicable law at that time; provided, further, that such limitation shall not free the Swiss Guarantor from its obligations in excess of the Maximum Amount, but merely postpone the performance date of those obligations until such time or times as performance is again permitted under then applicable law. This Maximum Amount of freely disposable shareholder equity shall be determined in accordance with Swiss law and applicable Swiss accounting principles, and, if and to the extent required by applicable Swiss law, shall be confirmed by the auditors of the Swiss Guarantor on the basis of an interim audited balance sheet as of that time.

(2)In respect of Upstream or Cross-Stream Guaranteed Obligations, at the time it is required to make a payment under this Indenture or the Notes,

-87-

the Swiss Guarantor shall, if and to the extent required by applicable law in force at the relevant time:

(A)use its best efforts to ensure that payment can be used to discharge Upstream or Cross-Stream Guaranteed Obligations without deduction of any taxes imposed under the Swiss Federal Act on the Withholding Tax (Bundesgesetz über die Verrechnungssteuer) of October 13, 1965, as amended from time to time (SR 642.21), together with the related ordinances, regulations and guidelines, all as amended and applicable from time to time (“Swiss Withholding Tax”) by discharging such tax liability by notification pursuant to applicable law rather than payment of the tax;

(B)if the notification procedure pursuant to sub-clause (i) above does not apply, deduct the Swiss Withholding Tax at such rate (currently 35% at the date of this Indenture) as is in force from time to time from any such payment used to discharge Upstream or Cross-Stream Guaranteed Obligations; or deduct Swiss Withholding Tax at the reduced rate resulting after discharge of part of such tax by notification if the notification procedure pursuant to sub clause (i) above applies for a part of Swiss Withholding Tax only, and pay, without delay, any such taxes deducted to the Swiss Federal Tax Administration;

(C)notify the Trustee that such notification or, as the case may be, deduction has been made, and provide the Trustee with evidence that such notification of the Swiss Federal Tax Administration has been made or, as the case may be, such taxes deducted have been paid to the Swiss Federal Tax Administration; and

(D)in the case of a deduction of Swiss Withholding Tax, use its best efforts to ensure that any Person, which is entitled to a full or partial refund of the Swiss Withholding Tax deducted from such payment, will, as soon as possible after such deduction,

(1) request a refund of the Swiss Withholding Tax under applicable law (including tax treaties), and

(2) pay to the Trustee upon receipt any amount so refunded.

(3)The Swiss Guarantor shall promptly take and promptly cause to be taken any action, including the following:

(A)the passing of any shareholders’ resolutions to approve the payment or other performance under this Article 10, which may be required as a matter of mandatory Swiss law in force at the time of the enforcement of the Guarantees or any other indemnity in order to allow a prompt payment;

-88-

(B)preparation of an up-to-date audited balance sheet of the Swiss Guarantor;

(C)confirmation of the auditors of the Swiss Guarantor that the relevant amount represents the Maximum Amount;

(D)conversion of restricted reserves into profits and reserves freely available for distribution as dividends (to the extent permitted by mandatory Swiss law);

(E)revaluation of hidden reserves (to the extent permitted by mandatory Swiss law);

(F)to the extent permitted by applicable law, Swiss accounting standards, and this Indenture and the Notes, write-up or realize any of its assets that are shown in the Swiss Guarantor’s balance sheet with a book value that is significantly lower than the market value of the assets, in case of realization, however, only if such assets are not necessary for the Swiss Guarantor’s business (nicht betriebsnotwendig); and

(G)all such other measures necessary or useful to allow the Swiss Guarantor to make payments as agreed hereunder with a minimum of limitations.

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

SECTION 10.2 Limitation on Liability.

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

SECTION 10.3 Successors and Assigns.

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

-89-

SECTION 10.4 No Waiver.

Neither a failure nor a delay on the part of either the Trustee or the Holders in exercising any right, power or privilege under this Article 10 shall operate as a waiver thereof, nor shall a single or partial exercise thereof preclude any other or further exercise of any right, power or privilege. The rights, remedies and benefits of the Trustee and the Holders herein expressly specified are cumulative and not exclusive of any other rights, remedies or benefits which either may have under this Article 10 at law, in equity, by statute or otherwise.

SECTION 10.5 Modification.

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

SECTION 10.6 Release of Subsidiary Guarantor.

(a)The Note Guarantee of a Subsidiary Guarantor will be automatically released and discharged:

(1)upon such Subsidiary Guarantor becoming an Excluded Subsidiary to the extent not prohibited by this Indenture;

(2)upon the release or discharge of such Subsidiary Guarantor as borrower or guarantor (as applicable) of, and of all Liens, if any, granted by such subsidiary in connection with the Amended Revolving Credit Agreement and any other Indebtedness that required such Subsidiary Guarantor to enter into a supplemental indenture to provide a Note Guarantee pursuant to Section 10.7, other than if such Subsidiary Guarantor would otherwise be required to enter into a supplemental indenture to provide a Note Guarantee pursuant to such Section 10.7 immediately upon such release;

(3)upon any sale, exchange, disposition, issuance or transfer (including by merger, amalgamation, consolidation or otherwise) of:

(b)A Subsidiary Guarantor may consolidate with, merge with or into, or liquidate or dissolve into, or transfer all or substantially all its assets to, any other Person to the extent set forth in Article 5, and upon completion of such a transaction in compliance with such Article 5, the Note Guarantee of such Subsidiary Guarantor will be automatically released and discharged.

SECTION 10.7 Execution of Guarantee Agreement for Future Subsidiary Guarantors.

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

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

Where this Indenture provides for notice in any manner, such notice may be waived in writing by the Person entitled to receive such notice, either before or after the event, and such waiver shall be the equivalent of such notice. Waivers of notice by Holders shall be filed with

-92-

the Trustee, but such filing shall not be a condition precedent to the validity of any action taken in reliance upon such waiver.

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

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

SECTION 11.2 Trustee Instructions.

The Trustee shall have the right to accept and act upon instructions, including funds transfer instructions (“Instructions”) given pursuant to this Indenture and delivered using Electronic Means; provided, however, that the Issuer and/or the Company, as applicable, shall provide to the Trustee an incumbency certificate listing officers with the authority to provide such Instructions (“Authorized Officers”) and containing specimen signatures of such Authorized Officers, which incumbency certificate shall be amended by the Issuer and/or the Company, as applicable, whenever a person is to be added or deleted from the listing. If the Issuer and/or the Company, 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 and the Company 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 and the Company shall be responsible for ensuring that only Authorized Officers transmit such Instructions to the Trustee and that the Issuer and the Company, as applicable, 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 and/or the Company, as applicable. The Trustee shall not be liable for any losses, costs or expenses arising directly or indirectly from the Trustee’s reliance upon and compliance with such Instructions notwithstanding such directions conflict or are inconsistent with a subsequent written instruction. The Issuer and the Company 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 and/or the Company, 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.

-93-

SECTION 11.3 Certificate and Opinion as to Conditions Precedent.

Upon any request or application by the Issuer to the Trustee to take or refrain from taking any action under this Indenture (except for authentication of the Notes by the Trustee on the Issue Date, which shall not require an Opinion of Counsel), the Issuer shall furnish to the Trustee:

(a)an Officer’s Certificate in form and substance reasonably satisfactory to the Trustee (which shall include the statements set forth in Section 11.4) to the effect that, in the opinion of the signers, all conditions precedent and covenants, if any, provided for in this Indenture relating to the proposed action have been complied with; and

(b)an Opinion of Counsel in form and substance reasonably satisfactory to the Trustee (which shall include the statements set forth in Section 11.4) to the effect that, in the opinion of such counsel, all such conditions precedent and covenants have been complied with.

SECTION 11.4 Statements Required in Certificate or Opinion.

Each certificate or opinion with respect to compliance with a covenant or condition provided for in this Indenture shall include:

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

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

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

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

SECTION 11.5 When Notes Disregarded.

In determining whether the Holders of the required principal amount of Notes have concurred in any direction, waiver or consent, Notes owned by the Issuer, 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 shall be disregarded and deemed not to be outstanding, except that, for the purpose of determining whether the Trustee shall be protected in relying on any such direction, waiver or consent, only Notes which the Trustee knows are so owned shall be so disregarded. Also, subject to the foregoing, only Notes outstanding at the time shall be considered in any such determination.

-94-

SECTION 11.6 Rules by Trustee, Paying Agent and Registrar.

The Trustee may make reasonable rules for action by or a meeting of Holders. The Trustee, the Registrar or the Paying Agent may make reasonable rules for their functions.

SECTION 11.7 Business Days.

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

SECTION 11.8 Governing Law.

This Indenture and the Notes shall be governed by, and construed in accordance with, the laws of the State of New York.

SECTION 11.9 No Recourse Against Others.

A past, present or future director, officer, employee, incorporator, member, partner or stockholder, as such, of the Issuer or any Guarantor, or of any stockholder of the Issuer or any Guarantor, shall not have any liability for any obligations of the Issuer or any Guarantor, either directly or through the Issuer or any Guarantor, as the case may be, under the Notes, Note Guarantees or this Indenture or for any claim based on, in respect of or by reason of such obligations or their creation whether by virtue of any rule of law, statute or constitutional provision or by the enforcement of any assessment or by any legal or equitable proceeding or otherwise. By accepting a Note, each Holder shall waive and release any and all such liability. The waiver and release shall be part of the consideration for the issue of the Notes.

SECTION 11.10 Successors.

All agreements of the Issuer and any Guarantor in this Indenture and the Notes shall bind their respective successors. All agreements of the Trustee in this Indenture shall bind its successors.

SECTION 11.11 Multiple Originals.

The parties may sign any number of copies of this Indenture. Each signed copy shall be an original, but all of them together represent the same agreement. The exchange of copies of this Indenture and of signature pages by PDF or other electronic transmission shall constitute effective execution and delivery of this Indenture as to the parties hereto and may be used in lieu of the original Indenture for all purposes. Signatures of all the parties hereto transmitted by PDF or other electronic means shall be deemed to be their original signatures for all purposes other than the Trustee’s signature on the certificate of authentication on each Note. Unless otherwise provided herein, the words “execute,” “execution,” “signed” and “signature” and words of similar import used in or related to any document to be signed in connection with this Indenture or any of the transactions contemplated hereby (including amendments, waivers, consents and other modifications) shall be deemed to include electronic signatures and the keeping of records in electronic form, each of which shall be of the same legal effect, validity or enforceability as a manually executed signature in ink or the use of a paper-based recordkeeping system, as

-95-

applicable, to the fullest extent and as provided for in any applicable law, including the Federal Electronic Signatures in Global and National Commerce Act, the New York State Electronic Signatures and Records Act and any other similar state laws based on the Uniform Electronic Transactions Act; provided that, notwithstanding anything herein to the contrary, the Trustee is under no obligation to agree to accept electronic signatures in any form or in any format unless expressly agreed to by the Trustee pursuant to reasonable procedures approved by the Trustee.

SECTION 11.12 Table of Contents; Headings.

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

SECTION 11.13 WAIVER OF TRIAL BY JURY.

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

SECTION 11.14 Force Majeure.

In no event shall the Trustee be responsible or liable for any failure or delay in the performance of its obligations hereunder arising out of or caused by, directly or indirectly, forces beyond its control, including, without limitation, strikes, work stoppages, accidents, acts of war or terrorism, civil or military disturbances, nuclear or natural catastrophes or acts of God, and interruptions, loss or malfunctions of utilities, communications or computer (software and hardware) services; it being understood that the Trustee shall use reasonable efforts that are consistent with accepted practices in the banking industry to resume performance as soon as practicable under the circumstances.

SECTION 11.15 USA Patriot Act Compliance.

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

-96-

SECTION 11.16 Submission to Jurisdiction.

Each of the Issuer and each Subsidiary Guarantor not organized in the United States hereby appoints the Company as its agent for service of process in any suit, action or proceeding with respect to this Indenture, the Notes and the Note Guarantees and for actions brought under the U.S. federal or state securities laws brought in any U.S. federal or state court located in the Borough of Manhattan in the County and City of New York. The Company hereby acknowledges and accepts its appointment by the Issuer and each Subsidiary Guarantor not organized in the United States. Such service may be made by mailing or delivering a copy of such process to the Issuer or such Subsidiary Guarantor not organized in the United States in care of the Company at its address as specified in Section 11.1 of this Indenture (or such other address as provided in a written notice to the Trustee). The Company, the Issuer and each Subsidiary Guarantor irrevocably and unconditionally submit to the exclusive jurisdiction of the U.S. federal or state courts sitting in the Borough of Manhattan in the County and City of New York over any suit, action or proceeding arising out of or relating to this Indenture, the Notes or the Note Guarantees and for actions brought under the U.S. federal or state securities laws. Service of any process on the Company in any such action (and written notice of such service to the Issuer) shall be effective service of process against the Issuer or any Guarantor with respect to any such suit, action or proceeding. The Company, the Issuer and each Subsidiary Guarantor irrevocably and unconditionally waive any objection to the laying of venue of any such suit, action or proceeding brought in any such court and any claim that any such suit, action or proceeding has been brought in an inconvenient forum. A final judgment in any such suit, action or proceeding brought in any such court shall be conclusive and binding upon the Company, the Issuer and each Subsidiary Guarantor and may be enforced in any other courts to whose jurisdiction the Issuer is or may be subject, by suit upon judgment. The Company, the Issuer and each Subsidiary Guarantor further agree that nothing herein shall affect any Holder’s right to effect service of process in any other manner permitted by law or bring a suit action or proceeding (including a proceeding for enforcement of a judgment) in any other court or jurisdiction in accordance with applicable law.

SECTION 11.17 Waiver of Immunity.

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

-97-

SECTION 11.18 Conversion of Currency.

If for the purposes of obtaining judgment in any court it is necessary to convert a sum due under this Indenture to the Holder from U.S. dollars to another currency, the Issuer and each Guarantor agree, and each Holder by holding such Note will be deemed to have agreed, to the fullest extent that the Issuer, each Guarantor and they may effectively do so, that the rate of exchange used shall be that at which in accordance with normal banking procedures such Holder could purchase U.S. dollars with such other currency in New York City, New York on the Business Day preceding the day on which final judgment is given.

The Issuer’s and Guarantors’ obligations to any Holder will, notwithstanding any judgment in a currency (the “Judgment Currency”) other than U.S. dollars, be discharged only to the extent that on the Business Day following receipt by such Holder or the Trustee, as the case may be, of any amount in such Judgment Currency, such Holder may in accordance with normal banking procedures purchase U.S. dollars with the Judgment Currency. If the amount of the U.S. dollars so purchased is less than the amount originally to be paid to such Holder or the Trustee in the Judgment Currency (as determined in the manner set forth in the preceding paragraph), as the case may be, each of the Issuer and the Guarantors, jointly and severally, agrees, as a separate obligation and notwithstanding any such judgment, to indemnify the Holder and the Trustee, as the case may be, against any such loss. If the amount of the U.S. dollars so purchased is more than the amount originally to be paid to such Holder or the Trustee, as the case may be, such Holder or the Trustee, as the case may be, will pay the Issuer and the Guarantors, such excess; provided that such Holder or the Trustee, as the case may be, shall not have any obligation to pay any such excess as long as a Default under the Notes or this Indenture has occurred and is continuing or if the Issuer or the Guarantors shall have failed to pay any Holder or the Trustee any amounts then due and payable under the Notes or this Indenture, in which case such excess may be applied by such Holder or the Trustee to such obligations.

SECTION 11.19 FATCA

The Paying Agent shall be entitled to deduct or withhold from payments under this Indenture to the extent necessary to comply with an agreement described in Section 1471(b) of the Code or otherwise imposed pursuant to FATCA. To the extent permitted under applicable privacy law and if expressly authorized by any agreement between the Issuer and such holder or beneficial owner or by the terms of any tax certification, the Issuer hereby covenants with the Trustee that it will use commercially reasonable efforts to provide the Trustee with any relevant tax certification in the possession of the Issuer or other information identified by the Issuer in its sole discretion as relevant for FATCA withholding tax purposes that may be useful to assist the Trustee to determine whether or not the Trustee is obliged, in respect of any payments to be made by it pursuant to this Indenture, to make any withholding or deduction pursuant to FATCA.

[FORM OF REVERSE SIDE OF NOTE]

6.625% Senior Note due 2034 (the “Notes”)

1. Interest

ALUMINA PTY LTD (ABN 85 004 820 419), a proprietary company limited by shares incorporated in Australia and registered in Victoria, Australia (such company, and its successors and assigns under the Indenture hereinafter referred to, being herein called the “Issuer”), promises to pay interest on the principal amount of this Note at the rate per annum shown above. The Issuer shall pay interest semiannually on March 31 and September 30 of each year. Interest on the Notes shall accrue from the most recent date to which interest has been paid or duly provided for or, if no interest has been paid or duly provided for, from September 23, 2026 until the principal hereof is due. Interest shall be computed on the basis of a 360-day year of twelve 30-day months.

2. Method of Payment

The Issuer shall pay interest on the Notes (except defaulted interest) to the Persons who are registered Holders at the close of business on the March 15 or September 15 next preceding the interest payment date; provided that for so long as the Notes are held by DTC, the Issuer shall pay interest on the Notes to the Persons who are registered Holders at the close of business on the Business Day immediately preceding the applicable interest payment date. The Issuer shall pay interest on the Notes on each interest payment date even if Notes are canceled after the record date and on or before the interest payment date. Holders must surrender Notes to a Paying Agent to collect principal payments. The Issuer shall pay principal, premium, if any, and interest in money of the United States of America that at the time of payment is legal tender for payment of public and private debts. Cash payments of principal of, premium, if any, and interest on the Notes are payable at the office or agency of the Issuer maintained for such purpose or, at the option of the Issuer, cash payment of interest may be made by check mailed to the Holders at their respective addresses or transmitted by wire in accordance with wiring instructions set forth in the register of Holders; provided, that (1) all cash payments of principal, premium, if any, and interest with respect to Global Notes registered in the name of or held by DTC or its nominee will be made by wire transfer of immediately available funds to the accounts specified by the registered Holder or Holders thereof and (2) all cash payments of principal, premium, if any, and interest with respect to certificated Notes will be made by wire transfer to a U.S. dollar account maintained by the payee with a bank in the United States if such Holder elects payment by wire transfer by giving written notice to the Trustee or the Paying Agent to such effect designating such account no later than 30 days immediately preceding the relevant due date for payment (or such other date as the Trustee may agree). Until otherwise designated by the Issuer, the Issuer’s office or agency is the office of the Trustee maintained for such purpose. If a payment date falls on a day that is not a Business Day, payment will be made on the next succeeding Business Day and no interest shall accrue for the intervening period.

A-6

3. Paying Agent and Registrar

Initially, The Bank of New York Mellon Trust Company, N.A. (the “Trustee”), shall act as Paying Agent and Registrar. The Issuer may appoint and change any Paying Agent or Registrar without notice. The Issuer or any of its wholly owned subsidiaries organized under the laws of the United States or any state thereof may act as Paying Agent (prior to an Event of Default), Registrar, co-registrar or transfer agent.

4. Indenture

The Issuer issued the Notes under an Indenture dated as of September 23, 2026 (the “Indenture”), among the Issuer, Alcoa Corporation (the “Company”), a Delaware corporation, the Subsidiary Guarantors party thereto and the Trustee. Terms defined in the Indenture and not defined herein have the meanings ascribed thereto in the Indenture. The Notes are subject to all terms and provisions of the Indenture and Holders are referred to the Indenture for a statement of such terms and provisions.

The Notes are senior unsecured obligations of the Issuer. The Issuer shall be entitled to issue Additional Notes pursuant to Section 2.15 of the Indenture. The Original Notes and any Additional Notes shall be treated as a single class for all purposes of the Indenture. The Indenture imposes certain limitations on the ability of the Company, the Issuer and certain of their subsidiaries to, among other things, create liens on certain assets to secure debt and enter into certain sale and leaseback transactions. The Indenture also imposes limitations on the ability of the Company, the Issuer and the Subsidiary Guarantors to consolidate, amalgamate or merge with or into any other Person or convey, transfer or lease all or substantially all their property.

To guarantee the due and punctual payment of the principal of, and interest on the Notes and all other amounts payable by the Issuer under the Indenture and the Notes when and as the same shall be due and payable, whether at maturity, by acceleration or otherwise, according to the terms of the Notes and the Indenture, the Company and the Subsidiary Guarantors have unconditionally guaranteed the Guaranteed Obligations on a senior unsecured basis pursuant to the terms of the Indenture. Certain other subsidiaries of the Company will be required to guarantee the Guaranteed Obligations on or after the Issue Date, subject to the limitations set forth in the Indenture.

5. Optional Redemption

Except as set forth in this Section 5, the Issuer shall not be entitled to redeem the Notes at its option.

(a) Prior to September 30, 2029, the Issuer will be entitled at its option to redeem all, but not less than all, of the Notes, upon not less than 10 nor more than 60 days’ notice, at a redemption price equal to 100% of the principal amount of the Notes plus the Applicable Premium as of, and accrued and unpaid interest to but not including, the redemption date (subject to the right of Holders of record on the relevant record date to receive interest due on the relevant interest payment date).

A-7

On and after September 30, 2029, the Issuer will be entitled at its option to redeem on one or more occasions all or a portion of the Notes, upon not less than 10 nor more than 60 days’ notice, at the redemption prices set forth below (expressed in percentages of principal amount on the redemption date), plus, in each case, accrued interest to but not including the redemption date (subject to the right of Holders of record on the relevant record date to receive interest due on the relevant interest payment date), if redeemed during the 12-month period commencing on September 30 of the years set forth below:

2029	103.313%
2030	101.656%
2031 and thereafter	100.000%

(b) In addition, at any time prior to September 30, 2029, the Issuer will be entitled at its option on one or more occasions to redeem the Notes, upon not less than 10 nor more than 60 days’ notice, in an aggregate principal amount not to exceed 40% of the aggregate principal amount of the Notes originally issued at a redemption price (expressed as a percentage of principal amount) of 106.625%, plus accrued and unpaid interest to but not including the redemption date (subject to the right of Holders of record on the relevant record date to receive interest due on the relevant interest payment date), if the principal and premium for such redemption is paid with the net cash proceeds from one or more Qualified Equity Offerings; provided, however, that

(1)at least 60% of the original aggregate principal amount of Notes remains outstanding immediately after the occurrence of each such redemption (other than Notes held, directly or indirectly, by the Company or its Affiliates); and

(2)each such redemption occurs within 180 days after the date of the related Qualified Equity Offering.

(c) The Issuer is also entitled to redeem the Notes, at its option, at any time as a whole but not in part, upon not less than 15 nor more than 60 days’ notice, at 100% of the principal amount thereof on the date of redemption, plus accrued and unpaid interest, if any, to, but not including, the date of redemption (subject to the right of Holders of record on the relevant record date to receive interest due on the relevant interest payment date), in the event the Issuer, the Company or any Subsidiary 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:

(1)a change in or an amendment to the laws (including any regulations promulgated thereunder) of a Relevant Taxing Jurisdiction (or any political subdivision or taxing authority thereof or therein) or the official entry or any change in the official application or interpretation of such laws or regulations; or

(2)any change in or amendment to any official position regarding the application or interpretation of such laws or regulations,

A-8

which change or amendment is announced or becomes effective on or after the Issue Date (or, if the Relevant Taxing Jurisdiction has changed since the Issue Date, the date on which such jurisdiction became a Relevant Taxing Jurisdiction) and it cannot avoid such obligation by taking reasonable measures available to it.

Before the Issuer delivers notice of redemption of the Notes as described above in this Section 5(c), it will deliver to the Trustee an Officer’s Certificate to the effect that it cannot avoid its obligation to pay Additional Amounts by taking reasonable measures available to it. The Issuer will also deliver an opinion of independent legal counsel of recognized standing stating that it would be obligated to pay Additional Amounts as a result of a change in tax laws or regulations or the application or interpretation of such laws or regulations.

(d) If Holders of not less than 90% in aggregate principal amount of the outstanding Notes validly tender and do not withdraw such Notes in a Change of Control Offer and the Issuer, or any third party making a Change of Control Offer in lieu of the Issuer as described in the Indenture, purchases all of the Notes validly tendered and not withdrawn by such Holders, the Issuer or such third party will have the right, upon not less than 15 days’ nor more than 60 days’ prior notice (provided that such notice is given not more than 30 days following such purchase pursuant to the Change of Control Offer described in the Indenture) to redeem all Notes that remain outstanding following such purchase at a price in cash equal to 101% of the principal amount thereof on the redemption date plus accrued and unpaid interest (if any) to but not including the redemption date (subject to the right of Holders of record on the relevant record date to receive interest due on the relevant interest payment date).

(e) Any optional redemption of the Notes under this Section 5 may, at the Issuer’s discretion, be subject to one or more conditions precedent, including completion of a Qualified Equity Offering, refinancing transaction or other corporate transaction. In addition, if such redemption or notice is subject to satisfaction of one or more conditions precedent, such notice shall state that, in the Issuer’s discretion, the redemption date may be delayed until such time as any or all of such conditions shall be satisfied (or waived by the Issuer in its sole discretion), or such redemption may not occur and such notice may be rescinded in the event that any or all such conditions shall not have been satisfied (or waived by the Issuer in its sole discretion) by the redemption date, or by the redemption date so delayed, and the redemption of the notes shall be rescinded or delayed as provided in such notice. If any condition precedent has not been satisfied, the Issuer will provide written notice to the Trustee prior to the close of business on the Business Day prior to the redemption date. Upon receipt of such notice, the notice of redemption shall be rescinded and the redemption of the Notes shall not occur or, if specified in such notice, the date of such redemption shall be extended to the specified date, which shall not be later than the latest date upon which such redemption is permitted to occur under this Section 5. Upon receipt, the Trustee shall provide such notice to each Holder of the Notes in the same manner in which the notice of redemption was given.

(f) The Notes are subject to Special Mandatory Redemption provisions as provided in Section 3.9 of the Indenture.

A-9

6. Sinking Fund

The Notes are not subject to any sinking fund.

7. Notice of Redemption

Notice of any redemption pursuant to Section 5(a) or (b) above shall be mailed by first-class mail (or otherwise delivered in accordance with the Applicable Procedures) at least 10 days but not more than 60 days before the redemption date to each Holder of Notes to be redeemed at his or her registered address and notice of any redemption pursuant to Section 5(c) or (d) above shall be mailed by first-class mail (or otherwise delivered in accordance with the Applicable Procedures) at least 15 days but not more than 60 days before the redemption date to each Holder of Notes to be redeemed at his or her registered address, except that, in each case, redemption notices may be mailed (or otherwise delivered in accordance with the Applicable Procedures) more than 60 days prior to the redemption date if the notice is issued in connection with a defeasance of the Notes or a satisfaction and discharge of the Indenture. Any inadvertent defect in the notice of redemption, including an inadvertent failure to give notice, to any Holder selected for redemption shall not impair or affect the validity of the redemption of any other Note redeemed in accordance with provisions of the Indenture. Notes in denominations of $200,000 or less may be redeemed in whole but not in part.

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

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

In accordance with Section 4.6 of the Indenture, the Issuer shall be required to offer to purchase Notes upon the occurrence of a Change of Control Repurchase Event. Any Holder of Notes shall have the right, subject to certain conditions specified in the Indenture, to cause the Issuer to repurchase all or any part of the Notes of such Holder at a purchase price equal to 101% of the principal amount of the Notes to be repurchased plus accrued and unpaid interest, if any, to, but excluding, the date of repurchase (subject to the right of Holders of record on the relevant record date to receive interest due on the relevant interest payment date) as provided in, and subject to the terms of, the Indenture.

9. Denominations; Transfer; Exchange

The Notes are in registered form without coupons in denominations of $200,000 and whole multiples of $1,000 in excess thereof. A Holder may transfer or exchange Notes in

A-10

accordance with the Indenture. Upon any transfer or exchange, the Registrar and the Trustee may require a Holder, among other things, to furnish appropriate endorsements or transfer documents and to pay any taxes required by law or permitted by the Indenture. The Issuer need not transfer or exchange any Note selected for redemption or tendered (and not withdrawn) for repurchase in connection with a Change of Control Offer, need not issue, register the transfer of or exchange any Note during the period of 15 days before the sending of a notice of redemption of Notes to be redeemed and need not register the transfer or exchange of any Note during the period of 15 days prior to an interest payment date.

10. Persons Deemed Owners

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

11. Unclaimed Money

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

12. Discharge and Defeasance

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

13. Amendment, Supplement and Waiver

Subject to certain exceptions, the Indenture may be amended 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 for the Notes) and any past default or compliance with any provisions may also be waived 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 for the Notes). However, without the consent of each Holder of an outstanding Note affected thereby, an amendment or waiver may not, among other things:

(1)reduce the amount of Notes whose Holders must consent to an amendment;

(2)reduce the rate of or extend the time for payment of interest on any Note;

A-11

(3)reduce the principal of or change the Stated Maturity of any Note;

(4)change the provisions applicable to the redemption of any Note as provided under Article 3, other than minimum or maximum notice requirements;

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

(6)modify the contractual right of a Holder to bring suit for the payment of principal, interest or premium (if any) on the Notes held by such Holder, on or after the respective due dates, including by modifying Section 6.7 of the Indenture;

(7)make any change in the amendment or waiver provisions which require each Holder’s consent as described in Sections 9.2(a)(1) through (6) or Sections 9.2(a)(8) and (9) of the Indenture;

(8)make any change in the ranking or priority of any Note or Note Guarantee that would adversely affect the Holders; or

(9)make any change in the provisions of Section 2.13 of the Indenture that adversely affects the rights of any Holder.

Notwithstanding the preceding, without the consent of any Holder, the Company, the Issuer and the Subsidiary Guarantors and the Trustee may amend the Indenture:

(1)to cure any ambiguity, omission, defect or inconsistency in the Indenture;

(2)to provide for the assumption by a successor entity of the obligations of the Company, the Issuer or any Subsidiary Guarantor under the Indenture;

(3)to provide for uncertificated Notes in addition to or in place of certificated Notes (provided that the uncertificated Notes are issued in registered form for purposes of Section 163(f) of the Code);

(4)to add Guarantees with respect to the Notes, including any Subsidiary Guarantee, or to secure the Notes;

(5)to add to the covenants of the Company, the Issuer or any Subsidiary Guarantor for the benefit of the Holders or to surrender any right or power conferred upon the Company, the Issuer or any Subsidiary Guarantor;

(6)to make any change that does not adversely affect the rights of any Holder in any material respect;

(7)to comply with any requirement of the SEC in connection with the qualification of the Indenture under the Trust Indenture Act;

A-12

(8)to conform the text of the Indenture, the Notes or any Note Guarantee to any provision of the “Description of Notes” in the Offering Memorandum, as determined in good faith by the Company;

(9)to make any amendment to the provisions of the Indenture relating to the transfer and legending of Notes; provided, however, that (A) compliance with the Indenture as so amended would not result in Notes being transferred in violation of the Securities Act or any other applicable securities law and (B) such amendment does not materially and adversely affect the rights of Holders to transfer Notes except as required to satisfy any applicable requirements of the securities laws, including any exemption from registration thereunder;

(10)to evidence and provide for the acceptance and appointment under the Indenture of a successor Trustee thereunder pursuant to the requirements thereof; and

(11)to provide for the issuance of Additional Notes in accordance with the terms of the Indenture.

14. Defaults and Remedies

Under the Indenture, each of the following is an Event of Default:

(1)a default in the payment of interest on the Notes when due, continued for 30 days;

(2)a default in the payment of principal of any Note when due at its Stated Maturity, upon redemption, upon required purchase, upon declaration of acceleration or otherwise, including the failure to consummate the Special Mandatory Redemption to the extent required by Section 3.9 of the Indenture;

(3)the failure by the Company, the Issuer or any Subsidiary Guarantor to comply with its obligations under Section 5.1 of the Indenture regarding certain mergers and consolidations;

(4)the failure by the Company, the Issuer or any Subsidiary Guarantor to comply for 60 days after notice with any of its obligations, covenants or other agreements under the Indenture or the Notes (other than a default referred to in clauses (1) or (2) or (3) above);

(5)default under any mortgage, indenture or instrument under which there is issued or by which there is secured or evidenced any Indebtedness for money borrowed by the Company, the Issuer or any Restricted Subsidiary (or the payment of which is Guaranteed by the Company, the Issuer or any

A-13

Restricted Subsidiary), whether such Indebtedness or Guarantee now exists, or is created after the Issue Date, which default:

(A)is caused by a failure to pay principal on such Indebtedness at its Stated Maturity (after giving effect to any applicable grace period provided in such Indebtedness) (“payment default”); or

(B)results in the acceleration of such Indebtedness prior to its maturity (the “cross acceleration provision”);

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 and remains unpaid, aggregates $250 million or more (or its foreign currency equivalent) (it being understood, for the avoidance of doubt, that Indebtedness owed to the Company, the Issuer or any Restricted Subsidiary shall not constitute Indebtedness for the purposes of this clause (5));

(6)failure by the Company, the Issuer or any Significant Subsidiary or any group of Restricted Subsidiaries that, taken together (as of the date of the latest consolidated financial statements of the Company made available to the Holders), would constitute a Significant Subsidiary to pay final judgments aggregating in excess of $250 million (or its foreign currency equivalent) (net of any amounts covered by a reputable and creditworthy insurance company), which judgments are not paid, discharged or stayed for a period of 90 days or more after such judgment becomes final and non-appealable (the “judgment default provision”);

(7)(A) the Company, the Issuer or a Significant Subsidiary or any group of Restricted Subsidiaries that, taken together (as of the date of the latest consolidated financial statements of the Company made available to the Holders), would constitute a Significant Subsidiary, pursuant to or within the meaning of any Bankruptcy Law:

(i)commences a voluntary case;

(ii)consents to the entry of an order for relief against it in an involuntary case or the filing by it of a petition or answer or consent seeking an arrangement of debt, reorganization, dissolution, winding up or relief under applicable Bankruptcy Law;

(iii)consents to the appointment of a Bankruptcy Custodian of it or for any substantial part of its property;

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

(i)is for relief against the Company, the Issuer or a Significant Subsidiary or any group of Restricted Subsidiaries that, taken together (as of the date of the latest consolidated financial statements of the Company made available to the Holders), would constitute a Significant Subsidiary, in an involuntary case;

However, a default under clause (4) or (6) will not constitute an Event of Default until the Trustee or the holders of 30% in principal amount of the Notes then outstanding notify the Company and the Issuer of the default and the Company and the Issuer do not cure such default within the time specified after receipt of such notice.

If an Event of Default occurs and is continuing, the Trustee or the holders of at least 30% in principal amount of the Notes then outstanding (by written notice to the Company and the Trustee) may declare the principal of and accrued but unpaid interest on all the Notes to be due and payable. Upon such a declaration, such principal and interest shall be due and payable immediately. If an Event of Default specified under clause (7) occurs and is continuing, the principal of and interest on all the Notes will ipso facto become and be immediately due and payable without any declaration or other act on the part of the Trustee or any Holders. Under certain circumstances, the Holders of a majority in principal amount of the Notes then outstanding may rescind any such acceleration with respect to the Notes and its consequences.

Holders may not enforce the Indenture or the Notes except as provided in the Indenture. The Trustee may refuse to enforce the Indenture or the Notes unless it receives indemnity or security reasonably satisfactory to it. Subject to certain limitations, Holders of a majority in principal amount of the Notes may direct the Trustee in its exercise of any trust or power. The Trustee may withhold from Holders notice of any continuing Default (except a Default in payment of principal or interest) so long as a committee of its Trust Officers in good faith determines that withholding notice is not opposed to the interest of the Holders.

15. Trustee Dealings with the Issuer

The Trustee under the Indenture, in its individual or any other capacity, may become the owner or pledgee of Notes and may otherwise deal with the Issuer or its Affiliates with the same rights it would have if it were not Trustee, subject to certain restrictions specified in the Indenture.

16. No Recourse Against Others

A past, present or future director, officer, employee, incorporator, member, partner or stockholder, as such, of the Issuer or any Guarantor, or of any stockholder of the Issuer or any Guarantor, shall not have any liability for any obligations of the Issuer or any Guarantor, either directly or through the Issuer or any Guarantor, as the case may be, under the Notes, Note Guarantees, or the Indenture or for any claim based on, in respect of or by reason of such obligations or their creation whether by virtue of any rule of law, statute or constitutional provision or by the enforcement of any assessment or by any legal or equitable proceeding or otherwise. By accepting a Note, each Holder shall waive and release any and all such liability. The waiver and release shall be part of the consideration for the issue of the Notes.

17. Authentication

This Note shall not be valid until an authorized signatory of the Trustee (or an authenticating agent) manually or electronically signs the certificate of authentication on the other side of this Note.

If any record date is set pursuant to this clause (c), the Holders on such record date, and only such Holders, shall be entitled to make, give or take such request, demand, authorization, direction, notice, consent, waiver or other action (including revocation of any action), whether or not such Holders remain Holders after such record date; provided that no such action shall be effective hereunder unless made, given or taken on or prior to the applicable expiration date by Holders of the requisite principal amount of Notes, or each affected Holder, as applicable, on such record date.

(e)Without limiting the foregoing, a Holder entitled to take any action hereunder with regard to any particular Note may do so with regard to all or any part of the principal amount of such Note or by one or more duly appointed agents, each of which may do so pursuant to such appointment with regard to all or any part of such principal amount. Any

-34-

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

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

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

(h)With respect to any record date set pursuant to this Section 1.4, the party hereto that sets such record date may designate any day as the “expiration date” and from time to time may change the expiration date to any earlier or later day; provided that no such change shall be effective unless notice of the proposed new expiration date is given to the other party hereto in writing, and to each Holder of Notes in the manner set forth in Section 11.1, on or prior to both the existing and the new expiration date. If an expiration date is not designated with respect to any record date set pursuant to this Section 1.4, the party hereto which set such record date shall be deemed to have initially designated the 30th day after such record date as the expiration date with respect thereto, subject to its right to change the expiration date as provided in this clause (h). No changed expiration date shall be more than 90 days from the initial expiration date.

(i)Any request, demand, authorization, direction, notice, consent, waiver or other action by the Holder of any Note shall bind every future Holder of the same Note and the Holder of every Note issued upon the registration of transfer thereof or in exchange therefor or in lieu thereof, in respect of any action taken, suffered or omitted by the Trustee, the Issuer or the Guarantors in reliance thereon, whether or not notation of such action is made upon such Note.

ARTICLE 2.

THE NOTES

SECTION 2.1 Form and Dating.

(a)The (i) Original Notes and the Trustee’s certificate of authentication and (ii) any Additional Notes (if issued as Transfer Restricted Notes) and the Trustee’s certificate of authentication shall be substantially in the form of Exhibit A hereto, as applicable, which is hereby incorporated in and expressly made a part of this Indenture. The Notes may have notations, legends or endorsements required by law, stock exchange rule, agreements to which the Issuer or any Guarantor is subject, if any, or usage (provided that any such notation, legend or endorsement is in a form acceptable to the Issuer but which notation, legend or endorsement does not affect the rights, duties or obligations of the Trustee). Each Note shall be dated the date of its authentication. The Notes shall be issuable only in registered form without interest coupons and only in denominations of $200,000 and whole multiples of $1,000 in excess thereof. The terms of the Notes set forth in the Exhibits hereto are part of the terms of this Indenture. However, to the extent any provision of any Note conflicts with the express provisions of this Indenture, the provisions of this Indenture shall govern and be controlling. The Notes issued on the Issue Date shall be (A) offered and sold by the Issuer pursuant to the Purchase Agreement and (B) resold, initially only to (1) QIBs in reliance on Rule 144A and (2) Persons other than U.S. Persons (as defined in Regulation S) in reliance on Regulation S. Such Notes may thereafter be transferred to, among others, QIBs and purchasers in reliance on Regulation S. Additional Notes offered after the Issue Date may be offered and sold by the Issuer from time to time in accordance with the provisions of this Indenture and applicable law.

(b)Global Notes. Notes offered and sold in their initial distribution in reliance on Rule 144A shall be issued in the form of one or more global notes in registered form, bearing the applicable legends set forth in Exhibit A, without interest coupons attached (“Rule 144A Global Notes”) deposited with the Trustee as custodian for the Depositary and registered in the name of Cede & Co., as nominee for the Depositary, duly executed by the Issuer and authenticated by the Trustee as herein provided, for credit by the Depositary to the respective accounts of beneficial owners of the Notes represented thereby (or such other accounts as they may direct). Notes offered and sold in their initial distribution in reliance on Regulation S shall be issued in the form of one or more global securities in fully registered form, bearing the applicable legends set forth in Exhibit A, without interest coupons attached (“Regulation S Global Notes”), deposited with the Trustee as custodian for the Depositary and registered in the name of Cede & Co., as nominee for the Depositary, duly executed by the Issuer and authenticated by the Trustee as herein provided, for credit by the Depositary to the respective accounts of beneficial owners of the Notes represented thereby (or such other accounts as they may direct). Rule 144A Global Notes and Regulation S Global Notes are referred to herein collectively as “Global Notes”. Beneficial interests in a Rule 144A Global Note may be transferred to a Person who takes delivery in the form of an interest in a Regulation S Global Note, whether before or after the expiration of the Restricted Period, only if the transferor first delivers to the Trustee a written certificate to the effect that such transfer is being made in accordance with Rule 903 or 904 of Regulation S or Rule 144 (if applicable). The aggregate principal amount of the Global Notes may from time to time be increased or decreased by adjustments made on the records of the Custodian and the Depositary or its nominee and on the schedules thereto as hereinafter provided.

-36-

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

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

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

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

SECTION 2.2 Execution and Authentication. One Officer shall sign the Notes for the Issuer by manual or electronic signature. 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 or electronically signs the certificate of authentication on the Note. The signature shall be conclusive evidence that the Note has been authenticated under this Indenture.

On the Issue Date, upon receipt of an Issuer Order, the Trustee shall authenticate and deliver $1,100,000,000 of Original Notes and, at any time and from time to time thereafter, the Trustee shall authenticate and deliver Additional Notes in an aggregate principal amount specified in an Issuer Order. Such Issuer Order shall specify the amount of the Additional Notes to be authenticated and the date on which the issue of Additional Notes is to be authenticated. The aggregate principal amount of Notes which may be authenticated and delivered under this Indenture is unlimited.

The Trustee may appoint an authenticating agent reasonably acceptable to the Issuer to authenticate the Notes. Any such appointment shall be evidenced by an instrument signed by a Trust Officer, a copy of which shall be furnished to the Issuer. Unless limited by the terms of such appointment, an authenticating agent may authenticate Notes whenever the 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 any Registrar, Paying Agent or agent for service of notices and demands.

SECTION 2.3 Registrar and Paying Agent.

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

(b)The Issuer shall enter into an appropriate agency agreement with any Registrar, Paying Agent or co-registrar not a party to this Indenture. The agreement shall implement the provisions of this Indenture that relate to such agent. The Issuer shall notify the Trustee in writing of the name and address of any such agent. If the Issuer fails to maintain a Registrar or Paying Agent, the Trustee shall act as such and shall be entitled to appropriate compensation and indemnification therefor pursuant to Section 7.6. The Issuer or any of its wholly owned subsidiaries organized under the laws of the United States or any state thereof may act as Paying Agent (prior to an Event of Default), Registrar, co-registrar or transfer agent.

(c)The Issuer may remove any Registrar or Paying Agent upon written notice to such Registrar or Paying Agent and to the Trustee; provided, however, that no such removal shall become effective until (i) acceptance of an appointment by a successor as evidenced by an appropriate agreement entered into by the Issuer and such successor Registrar or Paying Agent, as the case may be, and delivered to the Trustee and the passage of any waiting or notice periods required by the procedures of the Depositary or (ii) written notification to the Trustee that the Trustee shall serve as Registrar or Paying Agent until the appointment of a successor in accordance with clause (i) above. The Registrar or Paying Agent may resign at any time upon 30 days’ written notice to the Issuer and the Trustee.

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

-38-

SECTION 2.5 Holder Lists. The Trustee shall preserve in as current a form as is reasonably practicable the most recent list available to it of the names and addresses of Holders. If the Trustee is not the Registrar, the Issuer shall furnish to the Trustee, in writing at least five Business Days before each Interest Payment Date and at such other times as the Trustee may 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 Holders.

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

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

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

(ii)in the case of Transfer Restricted Notes that are Definitive Registered Notes, are being transferred or exchanged pursuant to an effective registration statement under the Securities Act or pursuant to clause (A), (B) or (C) below, and are accompanied by the following additional information and documents, as applicable:

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

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

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

Upon receipt by the Trustee of a Definitive Registered Note, duly endorsed or accompanied by appropriate instruments of transfer, in form satisfactory to the Trustee, together with:

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

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

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

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

-40-

Issuer so requests, an Opinion of Counsel or other evidence reasonably satisfactory to it as to the compliance with the restrictions set forth in the legend set forth in Section 2.6(e)(i).

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

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

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

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

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

-41-

BY ITS ACQUISITION HEREOF, THE HOLDER (1) REPRESENTS THAT (A) IT IS A “QUALIFIED INSTITUTIONAL BUYER” (AS DEFINED IN RULE 144A UNDER THE SECURITIES ACT) OR (B) IT IS NOT A U.S. PERSON AND IS ACQUIRING THIS SECURITY IN AN OFFSHORE TRANSACTION IN COMPLIANCE WITH REGULATION S UNDER THE SECURITIES ACT, (2) AGREES THAT IT WILL NOT RESELL OR OTHERWISE TRANSFER THIS SECURITY EXCEPT (A) TO THE ISSUER, ANY GUARANTOR OR ANY OTHER SUBSIDIARY THEREOF, (B) INSIDE THE UNITED STATES TO A “QUALIFIED INSTITUTIONAL BUYER” (AS DEFINED IN RULE 144A UNDER THE SECURITIES ACT) IN COMPLIANCE WITH RULE 144A UNDER THE SECURITIES ACT, (C) OUTSIDE THE UNITED STATES IN AN OFFSHORE TRANSACTION IN COMPLIANCE WITH RULE 903 OR RULE 904 OF REGULATION S UNDER THE SECURITIES ACT, (D) PURSUANT TO THE EXEMPTION FROM REGISTRATION PROVIDED BY RULE 144 UNDER THE SECURITIES ACT (IF AVAILABLE), (E) IN ACCORDANCE WITH ANOTHER EXEMPTION FROM THE REGISTRATION REQUIREMENTS OF THE SECURITIES ACT (AND BASED UPON AN OPINION OF COUNSEL IF THE ISSUER, ANY GUARANTOR OR ANY OTHER SUBSIDIARY THEREOF SO REQUEST), OR (F) PURSUANT TO AN EFFECTIVE REGISTRATION STATEMENT UNDER THE SECURITIES ACT AND (3) AGREES THAT IT WILL GIVE TO EACH PERSON TO WHOM THIS SECURITY IS TRANSFERRED A NOTICE SUBSTANTIALLY TO THE EFFECT OF THIS LEGEND. AS USED HEREIN, THE TERMS “OFFSHORE TRANSACTION,” “UNITED STATES” AND “U.S. PERSON” HAVE THE MEANING GIVEN TO THEM BY REGULATION S UNDER THE SECURITIES ACT.

In the case of Regulation S Notes, the Notes shall be the following additional legend:

BY ITS ACQUISITION HEREOF, THE HOLDER HEREOF REPRESENTS THAT IT IS NOT A U.S. PERSON, NOR IS IT PURCHASING FOR THE ACCOUNT OF A U.S. PERSON, AND IS ACQUIRING THIS SECURITY IN AN OFFSHORE TRANSACTION IN ACCORDANCE WITH REGULATION S UNDER THE SECURITIES ACT.

(ii)Upon any sale or transfer of a Transfer Restricted Note that is a Definitive Registered Note, the Registrar shall permit the Holder thereof to exchange such Transfer Restricted Note for a Definitive Registered Note that does not bear the Restricted Notes Legend and rescind any restriction on the transfer of

-42-

such Transfer Restricted Note if the Holder certifies in writing to the Registrar that its request for such exchange was made in reliance on Rule 144 (such certification to be in the form set forth on the reverse side of the Notes) and, if the Issuer so requests, an Opinion of Counsel or other evidence reasonably satisfactory to it as to the compliance with the restrictions set forth in the legend set forth in Section 2.6(e)(i).

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

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

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

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

(ii)No service charge shall be made for any registration of transfer or exchange, but the Issuer may require payment of a sum sufficient to cover any transfer tax, assessments, or similar governmental charge payable in connection therewith (other than any such transfer taxes, assessments or similar governmental charge payable upon exchanges pursuant to Sections 3.7, 4.6 and 9.4 of this Indenture).

(iii)The Issuer need not transfer or exchange any Note selected for redemption or tendered (and not withdrawn) for repurchase in connection with a Change of Control Offer, need not issue, register the transfer of or exchange any Note during the period of 15 days before the sending of a notice of redemption of Notes to be redeemed and need not register the transfer or exchange of any Note during the period of 15 days prior to an interest payment date.

(iv)Prior to the due presentation for registration of transfer of any Note, the Issuer, the Trustee, the Paying Agent, the Registrar or any co-registrar shall deem and treat the person in whose name a Note is registered as the absolute owner of such Note for the purpose of receiving payment of principal of and interest on such Note and for all other purposes whatsoever (whether or not such

-43-

Note is overdue) and none of the Issuer, the Trustee, the Paying Agent, the Registrar or any co-registrar shall be affected by notice to the contrary.

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

(h)No Obligation of the Trustee.

(i)The Trustee shall have no responsibility or obligation to any beneficial owner of a Global Note, a member of, or a participant in the Depositary or other Person with respect to the accuracy of the records of the Depositary or its nominee or of any participant or member thereof, with respect to any ownership interest in the Notes or with respect to the delivery to any participant, member, beneficial owner or other Person (other than the Depositary) of any notice (including any notice of redemption) or the payment of any amount, under or with respect to such Notes. All notices and communications to be given to the Holders and all payments to be made to Holders under the Notes shall be given or made only to or upon the order of the registered Holders (which shall be the Depositary or its nominee in the case of a Global Note). The rights of beneficial owners in any Global Note in global form shall be exercised only through the Depositary subject to the applicable rules and procedures of the Depositary. The Trustee may conclusively rely and shall be fully protected in relying upon information furnished by the Depositary with respect to its members, participants and any beneficial owners.

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

(iii)Transfer.

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

SECTION 2.7 Definitive Registered Notes.

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

(b)Any Global Note that is transferable to the beneficial owners thereof pursuant to this Section 2.7 shall be surrendered by the Depositary to the Trustee, to be so transferred, in whole or from time to time in part, without charge, and the Trustee shall authenticate and deliver, upon such transfer of each portion of such Global Note, an equal aggregate principal amount of Definitive Registered Notes of authorized denominations. Any portion of a Global Note transferred pursuant to this Section 2.7 shall be executed, authenticated and delivered only in denominations of $200,000 and integral multiples of $1,000 in excess thereof and registered in such names as the Depositary shall direct. Any certificated Note in the form of a Definitive Registered Note delivered in exchange for an interest in the Global Note shall, except as otherwise provided by Section 2.6(e), bear the Restricted Notes Legend.

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

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

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

-45-

SECTION 2.9 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 and those described in this Section 2.9 as not outstanding. A Note does not cease to be outstanding because the Issuer or an Affiliate of the Issuer holds the Note.

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

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

SECTION 2.10 Temporary Notes. In the event that Definitive Registered Notes are to be issued under the terms of this Indenture, until such Definitive Registered Notes are ready for delivery, the Issuer may prepare and the Trustee, upon receipt of an Issuer Order, shall authenticate temporary Notes. Temporary Notes shall be substantially in the form of Definitive Registered Notes but may have variations that the Issuer considers appropriate for temporary Notes. Without unreasonable delay, the Issuer shall prepare and the Trustee shall authenticate Definitive Registered Notes and deliver them in exchange for temporary Notes upon surrender of such temporary Notes at the office or agency of the Issuer, without charge to the Holder.

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

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

-46-

SECTION 2.13 Additional Amounts.

(a)All payments on the Notes will be made free and clear of and without withholding or deduction for or on account of any Taxes imposed or levied by or on behalf of the government of Australia, The Netherlands, the United States or, in each case, any political subdivision or any authority or agency therein or thereof having power to tax, or within any other jurisdiction in which the Issuer (or its successor), the Company (or its successor) or any Subsidiary Guarantor is organized or is otherwise resident for tax purposes or any jurisdiction from or through which payment is made (each a “Relevant Taxing Jurisdiction”), unless withholding or deduction is required by law or by the interpretation or administration thereof.

(b)If the Issuer, the Company or any Subsidiary Guarantor is so required to withhold or deduct any amount for or on account of Taxes imposed by a Relevant Taxing Jurisdiction from any payment made under or with respect to the Notes, the Issuer, the Company or such Subsidiary Guarantor will be required to pay such additional amounts (“Additional Amounts”) as may be necessary so that the net amount received by any Holder or beneficial owner (including Additional Amounts) after such withholding or deduction will not be less than the amount such Holder or beneficial owner would have received if such Taxes had not been withheld or deducted; provided, however, that the foregoing obligation to pay Additional Amounts does not apply to:

(1)any Taxes that would not have been so imposed but for the existence of any present or former connection between the relevant Holder or beneficial owner (or between a fiduciary, settlor, beneficiary, member or shareholder of, or possessor of power over, the relevant Holder, if the relevant Holder or beneficial owner is an estate, nominee, trust or corporation) and the Relevant Taxing Jurisdiction (other than the mere receipt of such payment or the ownership or holding outside of the Relevant Taxing Jurisdiction of such Note);

(2)any Taxes that would not have been imposed, withheld or deducted but for the failure by the Holder or the beneficial owner of the Note to comply with a written request of the Issuer, the Company or any Subsidiary Guarantor addressed to the Holder or the beneficial owner, after reasonable notice at least 30 days before any such Taxes would be imposed, withheld or deducted, to provide certification, information, documents or other evidence concerning the nationality, residence, identity or connection with the Relevant Taxing Jurisdiction of the Holder or such beneficial owners or to make any declaration or similar claim or satisfy any certification, identification, information or other reporting requirement relating to such matters, required by applicable law, regulation, treaty, any (multilateral) exchange of information regime, or administrative practice of, or entered into by, the Relevant Taxing Jurisdiction as a precondition to exemption from all or part of such Tax, including, for the avoidance of doubt, the failure of the Holder to provide its Australian tax file number or Australian business number (if applicable) or evidence of an exemption from doing so;

-47-

(3)any Taxes that are payable otherwise than by deduction or withholding from a payment under or with respect to the Notes or any Notes Guarantee;

(4)any estate, succession, death, goods and services or other value added, sales, transfer, stamp, issue, registration or similar Taxes;

(5)any Taxes imposed in connection with a Note presented for payment (where presentation is permitted or required for payment) by or on behalf of a Holder or beneficial owner who would have been able to avoid such Tax by presenting the relevant Note to, or otherwise accepting payment from, another paying agent;

(6)any Taxes which would not have been imposed if the Holder had presented the Note for payment (where presentation is permitted or required for payment) within 30 days after the relevant payment was first made available for payment to the Holder (except for Additional Amounts with respect to Taxes that would have been imposed had the Holder presented the Note for payment within such 30-day period);

(7)any Taxes imposed on or with respect to a payment to a Holder that is a fiduciary or partnership or any Person other than the sole beneficial owner of such payment or Note, to the extent that a beneficiary or settlor with respect to such fiduciary, a member of such partnership or the beneficial owner of such payment or Note would not have been entitled to the Additional Amounts had such beneficiary, settlor, member or beneficial owner been the actual Holder of such Note;

(8)any Taxes imposed pursuant to Sections 1471 to 1474 of the Code (or any regulations or agreements thereunder or official interpretations thereof) also referred to as “FATCA,” any intergovernmental agreement facilitating the implementation thereof (or any law implementing such intergovernmental agreement), any successor law or regulation implementing or complying with, or introduced in order to conform to, such sections of the Code, or any agreement entered into pursuant to Section 1471(b)(1) of the Code;

(9)any Tax imposed under the Australian Tax Act (or any associated legislation) in respect of amounts on the Notes which arises in circumstances where a Holder is the Issuer’s “associate” (as that term is defined in Section 128F(9) of the Australian Tax Act);

(10)any loss, liability or cost that arises as a result of a direction or notice being given under section 255 of the Australian Tax Act or section 260-5 of Schedule 1 to the Taxation Administration Act 1953 (Cth) or any analogous provision;

-48-

(11)any Taxes imposed pursuant to the Dutch Withholding Tax Act 2021 (Wet bronbelasting 2021); or

(12)any combination of the above.

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

(d)Upon request, the Issuer will provide the Trustee with official receipts, or official information reporting forms, or other documentation evidencing the payment of the Taxes with respect to which Additional Amounts are paid. The Issuer or the applicable Guarantor will also (i) make such withholding or deduction and (ii) remit the full amount deducted or withheld to the relevant authority in accordance with applicable law.

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

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

(g)The Issuer and the Guarantors shall indemnify and hold harmless the Trustee for the amount of any Taxes in respect of which the Issuer, or any Guarantor, is required to pay Additional Amounts pursuant to Section 2.13(b) that are levied or imposed and paid by the Trustee as a result of payments made under or with respect to the Notes or any Guarantee, including any reimbursements under this Section 2.13(g).

SECTION 2.14 CUSIP Numbers. The Issuer in issuing the Notes may use “CUSIP” numbers, ISINs and “Common Code” numbers (in each case if then generally in use) and, if so, the Trustee shall use “CUSIP” numbers, ISINs and “Common Code” numbers in notices of redemption as a convenience to Holders; provided, however, that any such notice may state that no representation is made as to the correctness of such numbers either as printed on the Notes or as contained in any notice of a redemption and that reliance may be placed only on the other identification numbers printed on the Notes, and any such redemption shall not be affected by any defect in or omission of such numbers. The Issuer will advise the Trustee in writing of any change in any “CUSIP” numbers, ISINs or “Common Code” numbers applicable to the Notes.

-49-

SECTION 2.15 Issuance of Additional Notes. After the Issue Date, the Issuer will be entitled to issue Additional Notes under this Indenture, which Notes shall have identical terms as the Notes issued on the Issue Date, other than with respect to the date of issuance, issue price, original interest accrual date and original interest payment date. All the Notes issued under this Indenture shall be treated as a single class for all purposes of this Indenture including waivers, amendments, redemptions and offers to purchase; provided that, such Additional Notes will have a separate CUSIP, ISIN or other identifying number unless the Additional Notes are issued pursuant to a “qualified reopening” of the original series, are otherwise treated as part of the same “issue” of debt instruments as the original series, or are issued with less than a de minimis amount of original discount, in each case for U.S. federal income tax purposes.

With respect to any Additional Notes, the Issuer will set forth in a resolution of the Board of Directors and an Officer’s Certificate, a copy of each which shall be delivered to the Trustee along with an Opinion of Counsel pursuant to Section 11.3, the following information:

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

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

SECTION 2.16 Computation of Interest.

(a)Interest shall be computed on the basis of a 360-day year comprised of twelve 30-day months.

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

ARTICLE 3.

REDEMPTION

SECTION 3.1 Notices to the Trustee. If the Issuer elects to redeem Notes pursuant to Section 5 of the Notes or otherwise in accordance with this Indenture, it shall notify the Trustee in writing of the redemption date and the principal amount of Notes to be redeemed.

The Issuer shall give each notice to the Trustee provided for in this Section 3.1 at least 5 days before the redemption date unless the Trustee consents to a shorter period. Such notice shall be accompanied by an Officer’s Certificate and an Opinion of Counsel from the Issuer to the effect that such redemption shall comply with the conditions herein. Any such notice may be canceled by written notice of the Issuer to the Trustee at any time prior to notice of such redemption being sent to any Holder pursuant to Section 3.4 and shall thereby be void and of no effect. This Section 3.1 shall not apply to any Special Mandatory Redemption pursuant to Section 3.9.

-50-

SECTION 3.2 Selection of Notes To Be Redeemed. If fewer than all the Notes are to be redeemed, selection of the Notes for redemption will be made by lot or otherwise in accordance with DTC procedures. The Issuer will redeem Notes of $200,000 or less in whole and not in part. Notes and portions of them selected for redemption shall be in principal amounts of $200,000 or a whole multiple of $1,000 in excess thereof, to the extent practicable. Provisions of this Indenture that apply to Notes called for redemption also apply to portions of Notes called for redemption. If any Note is to be redeemed in part only, the notice of redemption that relates to that Note will state the portion of the principal amount thereof to be redeemed. If the Notes are being redeemed other than on a pro rata basis, the Trustee shall notify the Issuer promptly of the Notes or portions of Notes to be redeemed.

SECTION 3.3 Effect of Notice of Redemption. Once a notice of redemption has been mailed or otherwise delivered under Section 3.4(a) or Section 3.9, Notes that are to be redeemed in accordance with such notice and the terms of this Article 3 shall become due and payable on the redemption date, subject where applicable to the satisfaction of any conditions in connection with the redemption. With respect to registered Notes issued in global form, the principal amount of such Note or Notes will be adjusted in accordance with the Applicable Procedures. With respect to any Notes represented by certificated notes, the Issuer will issue a new Note in a principal amount equal to the unredeemed portion of the original Note in the name of the holder upon cancelation of the original Note. Upon surrender to the Paying Agent, such Notes shall be paid under the terms stated in Section 3.4 and Section 3.9, as applicable; provided that if the redemption date is after a record date for the payment of interest and on or prior to the related Interest Payment Date, the accrued interest shall be payable to the Holder of the redeemed Notes registered on the relevant record date. On and after the redemption date, interest shall cease to accrue on Notes or portions thereof called for redemption.

SECTION 3.4 Notice of Redemption.

(a)At least 10 days but not more than 60 days before a date for redemption of Notes, the Issuer will mail a notice of redemption by first-class mail (or otherwise deliver in accordance with the applicable procedures of the Depositary) to each Holder of Notes to be redeemed at such Holder’s registered address, except that redemption notices may be sent (or otherwise delivered in accordance with the applicable procedures of the Depositary) more than 60 days prior to the redemption date if the notice is issued in connection with a defeasance of the Notes or a satisfaction and discharge of this Indenture. Any inadvertent defect in the notice of redemption, including an inadvertent failure to give notice, to any Holder selected for redemption shall not impair or affect the validity of the redemption of any other Note redeemed in accordance with the provisions of this Indenture. This Section 3.4(a) shall not apply to any Special Mandatory Redemption pursuant to Section 3.9.

(b)Any notice of redemption pursuant to Section 3.4(a) or Section 3.9 shall identify the Notes to be redeemed and shall state:

(i)the redemption date;

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

-51-

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

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

(v)solely in the case of a redemption pursuant to Section 3.4(a) (and not pursuant to Section 3.9), if fewer than all the outstanding Notes are to be redeemed (and if other than on a pro rata basis), the identification numbers and principal amounts (which amounts may be stated as a ratio of the amount to be redeemed per $1,000 principal amount outstanding) of the particular Notes to be redeemed;

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

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

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

(ix)solely in the case of a redemption pursuant to Section 3.4(a) (and not pursuant to Section 3.9), the conditions precedent, if any, applicable to such redemption. If such redemption or notice is subject to satisfaction of one or more conditions precedent, such notice shall state that, in the Issuer’s discretion, the redemption date may be delayed until such time as any or all of such conditions shall be satisfied (or waived by the Issuer in its sole discretion), or such redemption may not occur and such notice may be rescinded in the event that any or all such conditions shall not have been satisfied (or waived by the Issuer in its sole discretion) by the redemption date, or by the redemption date so delayed.

(c)At the Issuer’s request, upon written notice provided to the Trustee at least 3 days (unless a shorter period is satisfactory to the Trustee) prior to the date the redemption notice must be given to the Holders (provided no such notice shall be required for a redemption in accordance with Section 3.9), the Trustee shall give the notice of redemption in the Issuer’s name and at the Issuer’s expense. In such event, the Issuer will provide the Trustee with the information required by this Section 3.4 and Section 3.9, as applicable, and a copy of the proposed notice of redemption to be sent to the Holders.

(d)Any redemption notice pursuant to Section 3.4(a) (but not Section 3.9) may, at the Issuer’s discretion, be subject to one or more conditions precedent, including completion of a Qualified Equity Offering, refinancing transaction or other corporate transaction. If any condition precedent has not been satisfied, the Issuer will provide written notice to the Trustee prior to the close of business on the Business Day prior to the redemption date. Upon receipt of such notice, the notice of redemption shall be rescinded and the redemption of the Notes shall not occur or, if specified in such notice, the date of such redemption shall be

-52-

extended to the specified date, which shall not be later than the latest date upon which such redemption is permitted to occur under this Article 3. Upon receipt, the Trustee shall provide such notice to each Holder of the Notes in the same manner in which the notice of redemption was given.

SECTION 3.5 Tax Redemption. The Notes may be redeemed, at the option of the Issuer, in whole but not in part, at any time upon giving not less than 15 nor more than 60 days’ written notice to the Holders (which notice shall be irrevocable) in accordance with Section 3.4 hereof, at a redemption price equal to 100% of the principal amount thereof on the date of redemption, plus accrued and unpaid interest, if any, to but not including the date of redemption (subject to the right of Holders of record on the relevant record date to receive interest due on the relevant interest payment date) in the event the Issuer, the Company or any Subsidiary 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 (1) a change in or an amendment to the laws (including any regulations promulgated thereunder) of a Relevant Taxing Jurisdiction (or any political subdivision or taxing authority thereof or therein) or the official entry or any change in the official application or interpretation of such laws or regulations; or (2) any change in or amendment to any official position regarding the application or interpretation of such laws or regulations, which change or amendment is announced or becomes effective on or after the Issue Date (or, if the Relevant Taxing Jurisdiction has changed since the Issue Date, the date on which such jurisdiction became a Relevant Taxing Jurisdiction) and it cannot avoid such obligation by taking reasonable measures available to it. Before the Issuer delivers notice of redemption of the Notes as described above, it will deliver to the Trustee an Officer’s Certificate to the effect that it cannot avoid its obligation to pay Additional Amounts by taking reasonable measures available to it. The Issuer will also deliver an opinion of independent legal counsel of recognized standing stating that it would be obligated to pay Additional Amounts as a result of a change in tax laws or regulations or the application or interpretation of such laws or regulations. The provisions described under this Section 3.5 will survive any termination, defeasance or discharge of this Indenture and will apply mutatis mutandis to any jurisdiction in which any successor Person to the Issuer is organized or any political subdivision or taxing authority or agency thereof or therein. Any Notes that are redeemed pursuant to this Section 3.5 shall be cancelled.

SECTION 3.6 Deposit of Redemption Price. On or prior to 10:00 a.m. New York City time on the relevant redemption date, the Issuer will deposit with the Paying Agent (or, if the Issuer or a wholly owned subsidiary is the Paying Agent, shall segregate and hold in trust) money sufficient to pay the redemption price of and accrued interest, and Applicable Premium, if any, on all Notes or portions thereof to be redeemed on that date (including for any redemption pursuant to Section 3.4(a) or Section 3.9) other than Notes or portions of such Notes called for redemption that have been delivered by the Issuer to the Trustee for cancelation. On and after the redemption date, interest shall cease to accrue on Notes or portions thereof called for redemption so long as the Issuer has deposited with the Paying Agent funds sufficient to pay the principal of, plus accrued and unpaid interest, and Applicable Premium, if any, on, the Notes to be redeemed, unless the Paying Agent is prohibited from making such payment pursuant to the terms of this Indenture.

SECTION 4.4 Limitation on Liens.

(a)Neither the Company nor the Issuer shall, nor shall the Company or the Issuer permit any Restricted Subsidiary to, Incur any Lien (other than Permitted Liens) on any Principal Property now owned or hereafter acquired by it, to secure any Indebtedness of the Company, the Issuer or any Restricted Subsidiary, unless contemporaneously with the Incurrence of such Liens:

(1)in the case of Liens securing Subordinated Obligations, the Notes and related Note Guarantees are secured by a Lien on such Principal Property that is senior in priority to such Liens; or

(2)in all other cases, the Notes and related Note Guarantees are equally and ratably secured or are secured by a Lien on such Principal Property that is senior in priority to such Liens.

(b)Any Lien created for the benefit of Holders pursuant to this Section 4.4 shall be automatically and unconditionally released and discharged upon the release and discharge of each of the Liens that gave rise to the obligation to secure the Notes and related Note Guarantees pursuant to Sections 4.4(a)(1) and (2).

(c)For the purpose of this Section 4.4:

(1)Guarantees of, or obligations in respect of letters of credit relating to, Indebtedness that is otherwise included in the determination of a particular amount of Indebtedness shall not be included;

(2)if obligations in respect of letters of credit are Incurred pursuant to a credit agreement and are being treated as Incurred under clause (1) or (17) of the definition of Permitted Liens and the letters of credit relate to other Indebtedness, then such other Indebtedness shall not be included;

(3)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 GAAP;

(4)accrual of interest, accrual of dividends, the accretion of accreted value or original issue discount, the amortization of debt discount and the payment of interest in the form of additional indebtedness will not be deemed to be an Incurrence of the Indebtedness secured by the relevant Lien, and the amount of any Indebtedness secured by the relevant Lien outstanding as of any date shall be the accreted value thereof in the case of any Indebtedness issued with original issue discount or the aggregate principal amount outstanding in the case of Indebtedness issued with interest payable in kind and (ii) the principal amount or liquidation preference thereof, together with any interest thereon that is more than 30 days past due, in the case of any other Indebtedness;

-57-

(5)in determining compliance with any U.S. dollar-denominated restriction on the securing of Indebtedness, the U.S. dollar-equivalent principal amount of Indebtedness denominated in a foreign currency shall be calculated based upon 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;

(6)the principal amount of any Indebtedness Incurred to refinance other Indebtedness that is secured by a Lien, 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 refinancing indebtedness is denominated that is in effect on the date of such refinancing;

(7)in the case of any refinancing of any Indebtedness secured by any relevant Liens or any portion thereof, the amount of Indebtedness, being Incurred to finance the aggregate amount of fees (including upfront, commitment and ticking fees and original issue discount), underwriting discounts, penalties or premiums (including reasonable tender premiums), defeasance and satisfaction and discharge costs, accrued interest and other costs and expenses incurred in connection with such refinancing will not be deemed to be an Incurrence of Indebtedness secured by such Liens;

(8)notwithstanding anything in this Section 4.4 to the contrary, in the case of any Indebtedness Incurred to refinance Indebtedness secured by any relevant Liens, where such Liens are initially Incurred under the definition of Permitted Liens and measured by reference to a percentage of Consolidated Total Assets at the time of Incurrence, and such refinancing would cause the percentage of Consolidated Total Assets restriction to be exceeded if calculated based on the percentage of Consolidated Total Assets on the date of such refinancing, such percentage of Consolidated Total Assets restriction shall not be deemed to be exceeded so long as the principal amount of such refinancing Indebtedness, does not exceed the principal amount of such Indebtedness being refinanced, plus the aggregate amount of fees (including upfront, commitment and ticking fees and original issue discount), underwriting discounts, penalties or premiums (including reasonable tender premiums), defeasance and satisfaction and discharge costs and other costs and expenses incurred in connection with such refinancing; and

-58-

(9)the maximum amount of Indebtedness that the Company, the Issuer and the Restricted Subsidiaries may secure shall not be deemed to be exceeded solely as a result of fluctuations in the exchange rate of currencies.

SECTION 4.5 Limitation on Sale and Leaseback Transactions.

(a)The Company and the Issuer will not, and will not permit any Restricted Subsidiary to, enter into any arrangement (a “Sale and Leaseback Transaction”) with any Person providing for the leasing to the Company, the Issuer or any Restricted Subsidiary of any Principal Property, where such Principal Property has been or is to be sold or transferred by the Company, the Issuer or such Restricted Subsidiary to such Person, unless either:

(1)the Company, the Issuer or such Restricted Subsidiary would be entitled to create a Lien on such Principal Property securing an amount at least equal to the Attributable Debt with respect to such arrangement, without equally and ratably securing (or securing on a senior basis, as applicable) the Notes or the Note Guarantees pursuant to Section 4.4; or

(2)the Company applies an amount equal to the greater of the net proceeds of such sale or the Attributable Debt with respect to such arrangement to the retirement of Indebtedness that matures more than twelve months after the creation of such Indebtedness or to the purchase of assets that are useful to the Company’s business or a combination thereof.

(b)This restriction on Sale and Leaseback Transactions does not apply to any transaction (A) involving a lease for a term of not more than three years (or which may be terminated by the Company, the Issuer or the applicable Restricted Subsidiary within 3 years); or (B) between any of the Company, the Issuer or the Restricted Subsidiaries.

(c)Notwithstanding the foregoing, the Company, the Issuer and the Restricted Subsidiaries may enter into a Sale and Leaseback Transaction in addition to those permitted above, provided, however, that after giving effect thereto, Exempted Debt does not exceed 10% of Consolidated Total Assets of the Company measured as of the date of Incurrence of any Exempted Debt.

(d)For the purpose of this Section 4.5:

(1)in determining compliance with any U.S. dollar-denominated restriction on the entering into of any Sale and Leaseback Transaction, the U.S. dollar-equivalent principal amount of Attributable Debt denominated in a foreign currency shall be calculated based upon the relevant currency exchange rate in effect on the date such Attributable Debt was Incurred in respect of such Sale and Leaseback Transaction; and

(2)the maximum amount of Attributable Debt that the Company, the Issuer and the Restricted Subsidiaries may Incur in respect of any Sale and Leaseback Transaction shall not be deemed to be exceeded solely as a result of fluctuations in the exchange rate of currencies.

On and after the purchase date, interest will cease to accrue on the Notes or portions thereof purchased.

(e)The Issuer will not be required to make a Change of Control Offer following a Change of Control Repurchase Event if (1) a third party makes the Change of Control Offer in the manner, at the times and otherwise in compliance with the requirements set forth in this Indenture applicable to a Change of Control Offer made by the Issuer and purchases all Notes validly tendered and not withdrawn under such Change of Control Offer or (2) a notice of redemption in respect of all of the outstanding Notes that is or has become unconditional has been given as described under Article 3.

In the event that the Change of Control has not occurred as of the purchase date for the Change of Control Offer specified in the notice therefor (or amendment thereto), the Issuer (or third party offeror) may, in its discretion, rescind such notice or amend it to specify another purchase date.

(6)failure by the Company, the Issuer or any Significant Subsidiary or any group of Restricted Subsidiaries that, taken together (as of the date of the latest consolidated financial statements of the Company made available to the Holders), would constitute a Significant Subsidiary to pay final judgments aggregating in excess of $250 million (or its foreign currency equivalent) (net of any amounts covered by a reputable and creditworthy insurance company), which judgments are not paid, discharged or stayed for a period of 90 days or more after such judgment becomes final and non-appealable (the “judgment default provision”);

(7)(A) the Company, the Issuer or a Significant Subsidiary or any group of Restricted Subsidiaries that, taken together (as of the date of the latest consolidated financial statements of the Company made available to the Holders), would constitute a Significant Subsidiary, pursuant to or within the meaning of any Bankruptcy Law:

(i)commences a voluntary case;

(ii)consents to the entry of an order for relief against it in an involuntary case or the filing by it of a petition or answer or consent seeking an arrangement of debt, reorganization, dissolution, winding up or relief under applicable Bankruptcy Law;

(iii)consents to the appointment of a Bankruptcy Custodian of it or for any substantial part of its property; or

(iv)makes a general assignment for the benefit of its creditors;

or takes any comparable action under any foreign laws relating to insolvency; or

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

(i)is for relief against the Company, the Issuer or a Significant Subsidiary or any group of Restricted Subsidiaries that, taken together (as of the date of the latest consolidated financial statements of the Company made available to the Holders), would constitute a Significant Subsidiary, in an involuntary case;

(ii)appoints a Bankruptcy Custodian of the Company, the Issuer or a Significant Subsidiary or any group of Restricted Subsidiaries that, taken together (as of the date of the latest consolidated financial statements of the Company made available to the Holders), would constitute a Significant Subsidiary, or for any substantial part of the property of any of the foregoing; or

-67-

(iii)orders the winding up or liquidation of the Company, the Issuer or a Significant Subsidiary or any group of Restricted Subsidiaries that, taken together (as of the date of the latest consolidated financial statements of the Company made available to the Holders), would constitute a Significant Subsidiary;

or any similar relief is granted under any foreign laws and the order or decree remains unstayed and in effect for 90 days (the provisions of this Section 6.1(a)(7) being the “bankruptcy provisions”); or

(8)the Note Guarantee of the Company, or any Note Guarantee of a Significant Subsidiary or any group of Subsidiary Guarantors that, taken together (as of the date of the latest consolidated financial statements of the Company made available to the Holders), would constitute a Significant Subsidiary, ceases to be in full force and effect (except as contemplated by the terms of this Indenture) or is declared null and void in a final and non-appealable judicial proceeding or a responsible officer of the Company or any Subsidiary Guarantor that is a Significant Subsidiary or the responsible officers of any group of Subsidiary Guarantors that, taken together (as of the date of the latest consolidated financial statements of the Company made available to the Holders), would constitute a Significant Subsidiary, denies or disaffirms in writing its obligations under this Indenture or its Note Guarantee, other than by reason of the termination of this Indenture or release of any such Note Guarantee in accordance with this Indenture.

The foregoing clauses shall constitute Events of Default whatever the reason for any such Event of Default and whether it is voluntary or involuntary or is effected by operation of law or pursuant to any judgment, decree or order of any court or any order, rule or regulation of any administrative or governmental body.

However, a default under Section 6.1(a)(4) or (6) will not constitute an Event of Default until the Trustee or the holders of 30% in principal amount of the Notes then outstanding notify the Company and the Issuer of the default and the Company and the Issuer do not cure such default within the time specified after receipt of such notice. Any default for the failure to deliver any report within the time periods prescribed in Section 4.2 or to deliver any notice or certificate pursuant to any other provision of this Indenture shall be deemed to be cured upon the subsequent delivery of any such report, notice or certificate, even though such delivery is not within the prescribed period specified.

The term “Bankruptcy Law” means any law relating to bankruptcy, insolvency, receivership, winding-up, liquidation, reorganization or relief of debtors or any amendment to, succession to or change in any such law, including, without limitation, the United States Bankruptcy Code, 11 United States Code §§ 101 et seq. The term “Bankruptcy Custodian” means any receiver, trustee, assignee, liquidator, custodian or similar official under any Bankruptcy Law.

-68-

The Company shall deliver to the Trustee, within 30 days after obtaining knowledge of the occurrence thereof, written notice in the form of an Officer’s Certificate of any Default, its status and what action the Company is taking or proposes to take with respect thereto.

SECTION 6.2 Acceleration. If an Event of Default occurs and is continuing with respect to the Notes, the Trustee (by written notice to the Company) or the holders of at least 30% in principal amount of the Notes then outstanding (by written notice to the Company and the Trustee) may declare the principal of and accrued but unpaid interest on all the Notes to be due and payable. Upon such a declaration, such principal and interest shall be due and payable immediately. If an Event of Default specified under Section 6.1(a)(7) occurs and is continuing, the principal of and interest on all the Notes will ipso facto become and be immediately due and payable without any declaration or other act on the part of the Trustee or any Holders. At any time after a declaration of acceleration has been made, but before a judgment or decree for payment of the money due has been obtained, the Holders of not less than a majority in aggregate principal amount of the Notes by notice to the Trustee may rescind and annul that declaration of acceleration and its consequences if the rescission and annulment would not conflict with any judgment or decree and if all existing Events of Default have been cured or waived except nonpayment of principal or interest that has become due solely because of acceleration. No such rescission shall affect any subsequent Default or impair any right consequent thereto.

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

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 in exercising any right or remedy accruing upon an Event of Default shall not impair the right or remedy or constitute a waiver of or acquiescence in the Event of Default. No remedy is exclusive of any other remedy. All available remedies are cumulative.

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

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

-69-

with such direction. Prior to taking any action hereunder, the Trustee shall be entitled to indemnification or security reasonably satisfactory to it against any loss, liability or expense caused by taking or not taking such action.

SECTION 6.6 Limitation on Suits.

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

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

(2)Holders of at least 30% in principal amount of the Notes then outstanding have requested the Trustee to pursue the remedy;

(3)such Holders have offered the Trustee security or indemnity satisfactory to it against any loss, liability or expense;

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

(5)Holders of a majority in principal amount of the Notes then outstanding have not given the Trustee a direction inconsistent with such request within such 60-day period.

(b)A Holder may not use this Indenture to prejudice the rights of another Holder or to obtain a preference or priority over another Holder, it being understood that the Trustee has no affirmative duty to ascertain whether or not any actions or forbearances by a Holder are unduly prejudicial to other Holders. In the event that the Definitive Registered Notes are not issued to any beneficial owner promptly after the Registrar has received a request from the Holder of a Global Note to issue such Definitive Registered Notes to such beneficial owner of its nominee, the Issuer expressly agrees and acknowledges, with respect to the right of any Holder to pursue a remedy pursuant to this Indenture, the right of such beneficial holder of Notes to pursue such remedy with respect to the portion of the Global Note that represents such beneficial holder’s Notes as if such Definitive Registered Notes had been issued.

SECTION 6.7 Rights of Holders to Receive Payment. Notwithstanding any other provision of this Indenture, the contractual right of a Holder to bring suit for the payment of principal, interest or premium (if any) on the Notes held by such Holder, on or after the respective due dates, shall not be modified without the consent of such Holder.

SECTION 6.8 Collection Suit by Trustee. If an Event of Default specified in Section 6.1(a)(1) or (2) occurs and is continuing, the Trustee may recover judgment in its own name and as trustee of an express trust against the Issuer or any other obligor on the Notes for the whole amount then due and owing (together with interest on overdue principal and (to the extent lawful) on any unpaid interest at the rate provided for in the Notes) and the amounts provided for in Section 7.6.

-70-

SECTION 6.9 Trustee May File Proofs of Claim. The Trustee may file such proofs of claim and other papers or documents and take such other actions, including participating as members, voting or otherwise, of any committee of creditors appointed in the matter, as may be necessary or advisable in order to have the claims of the Trustee (including any claim for the reasonable compensation, expenses, disbursements and advances of the Trustee, and its agents and counsel) and the Holders allowed in any judicial proceedings relative to the Company, the Issuer or any Subsidiary Guarantor, their creditors or their property and, unless prohibited by law or applicable regulations, may vote on behalf of the Holders in any election of a trustee in bankruptcy or other Person performing similar functions, and any custodian in any such judicial proceeding is hereby authorized by each Holder to make payments to the Trustee and, in the event that the Trustee shall consent to the making of such payments directly to the Holders, to first pay to the Trustee any amount due 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 7.6.

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

FIRST: to the Trustee, its agents and attorneys, for amounts due under Section 7.6;

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

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

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

SECTION 6.11 Undertaking for Costs. In any suit for the enforcement of any right or remedy under this Indenture or in any suit against the Trustee for any action taken or omitted by it as Trustee, a court in its discretion may require the filing by any party litigant in the suit of an undertaking to pay the costs of the suit, and the court in its discretion may assess reasonable costs, including reasonable attorneys’ fees and expenses, against any party litigant in the suit, having due regard to the merits and good faith of the claims or defenses made by the party litigant. This Section 6.11 does not apply to a suit by the Issuer, a suit by the Trustee, a suit by a Holder pursuant to Section 6.7 or a suit by Holders of more than 10.0% in aggregate principal amount of the then outstanding Notes.

-71-

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

ARTICLE 7.

TRUSTEE

SECTION 7.1 Duties of Trustee.

(a)If an Event of Default has occurred and is continuing, the Trustee shall exercise the rights and powers vested in it by this Indenture and use the same degree of care and skill in its exercise as a prudent Person would exercise or use under the circumstances in the conduct of such Person’s own affairs.

(b)Except during the continuance of an Event of Default:

(i)the Trustee undertakes to perform such duties and only such duties as are specifically set forth in this Indenture and the Trustee shall not be liable except for the performance of such duties, and no implied covenants or obligations shall be read into this Indenture against the Trustee; and

However, in the case of any such certificates or opinions which by any provision hereof are specifically required to be furnished to the Trustee, the Trustee shall be under a duty to examine the same to determine whether or not they conform on their face to the requirements of this Indenture (but need not confirm or investigate the accuracy of mathematical calculations or other facts stated therein). The Trustee may (but shall in no way be obligated to) make further inquiry or investigation into such facts or materials as it sees fit.

(c)The Trustee may not be relieved from liability for its own negligent action, its own negligent failure to act, or bad faith or its own willful misconduct, except that:

(f)No provision of this Indenture shall require the Trustee to expend or risk its own funds or otherwise incur financial liability in the performance of any of its duties hereunder or in the exercise of any of its rights or powers, if it shall have reasonable grounds to believe that repayment of such funds or adequate indemnity against such risk or liability is not reasonably assured to it.

(g)Every provision of this Indenture relating to the conduct or affecting the liability of or affording protection to the Trustee shall be subject to the provisions of Article 7.

SECTION 7.2 Rights of Trustee.

(b)Before the Trustee acts or refrains from acting, it may require an Officer’s Certificate or an Opinion of Counsel or both conforming to Section 11.3. The Trustee shall not be liable for any action it takes or omits to take in good faith in conclusive reliance on the Officer’s Certificate or Opinion of Counsel.

(c)The Trustee may act through attorneys and agents and shall not be responsible for the misconduct or negligence of any agent appointed with due care.

(d)The Trustee shall not be liable for any action it takes or omits to take in good faith which it believes to be authorized or within its rights or powers; provided, however, that the Trustee’s conduct does not constitute bad faith, willful misconduct or negligence.

(f)The Trustee shall not be required to give any bond or surety in respect of the performance of its powers and duties hereunder.

(g)The Trustee shall not be bound to ascertain or inquire as to the performance or observance of any covenants, conditions, or agreements on the part of the Issuer, but the Trustee may require of the Issuer full information and advice as to the performance of the covenants, conditions and agreements contained herein.

(h)The permissive rights of the Trustee to do things enumerated in this Indenture shall not be construed as a duty.

(i)The Trustee shall not be deemed to have notice or be charged with knowledge of any Default or Event of Default unless a Trust Officer of the Trustee has received from the Issuer or the Holders of not less than 30% in aggregate principal amount of the Notes then outstanding written notice thereof at the Corporate Trust Office of the Trustee, and such notice references the Notes and this Indenture.

(j)The rights, privileges, protections, immunities and benefits given to the Trustee, including, without limitation, its right to be indemnified, are extended to, and shall be enforceable by, the Trustee and each other agent, custodian and Person employed to act hereunder.

(k)In no event shall the Trustee be responsible or liable for special, indirect, punitive, incidental or consequential loss or damage of any kind whatsoever (including, but not limited to, loss of profit) irrespective of whether the Trustee has been advised of the likelihood of such loss or damage and regardless of the form of action.

(l)Any request or direction of the Issuer or other Person mentioned herein shall be sufficiently evidenced by an Officer’s Certificate or certificate of an Officer of such other Person and any resolution of the Board of Directors of the Issuer or of such other Person may be sufficiently evidenced by a board resolution certified by the secretary or assistant secretary (or similar officer) of such Person.

(m)The Trustee may request that the Issuer deliver a 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 certificate may be updated and delivered to the Trustee at any time by the Issuer in its discretion.

-74-

(n)The Trustee will be under no obligation to exercise any of the rights or powers vested in it by this Indenture at the request or direction of any Holders unless such Holders have offered to the Trustee indemnity or security reasonably satisfactory to it against any loss, liability or expense that might be incurred by it in compliance with such request or direction.

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

(p)The delivery of reports, information and documents to the Trustee is for informational purposes only, and the Trustee’s receipt of such shall not constitute actual or constructive notice or knowledge of any information contained therein or determinable from information contained therein, including the Issuer’s compliance with any of its covenants under this Indenture (as to which the Trustee is entitled to rely exclusively on Officer’s Certificates).

SECTION 7.3 Individual Rights of the 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 its Affiliates with the same rights it would have if it were not Trustee; and any Paying Agent, Registrar or any other agent of the Trustee may do the same with like rights; provided, however, that if any of them acquire any “conflicting interest” (within the meaning of Section 310(b) of the Trust Indenture Act), they must eliminate such conflict within 90 days or resign in accordance with the terms of this Indenture.

SECTION 7.4 Trustee’s Disclaimer. The Trustee shall not be responsible for and makes no representation as to the validity or adequacy of this Indenture or the Notes, it shall not be accountable for the Issuer’s use of the proceeds from the Notes, and it shall not be responsible for any statement of the Issuer or any other Person in this Indenture or in any document issued in connection with the sale of the Notes or in the Notes other than the Trustee’s certificate of authentication.

SECTION 7.5 Notice of Defaults. If a Default occurs and is continuing and a Trust Officer shall have received written notice thereof at its Corporate Trust Office and such notice references the Notes and this Indenture, the Trustee shall send to each Holder a notice of the Default within 90 days after it occurs. Except in the case of a Default specified in Sections 6.1(a)(1) or (2), the Trustee may withhold from Holders notice of any continuing Default if a committee of its Trust Officers determines in good faith that withholding the notice is not opposed to the interests of such Holders.

SECTION 7.6 Compensation and Indemnity.

(a)The Issuer and the Guarantors, jointly and severally, shall pay to the Trustee from time to time such compensation for its services as shall be agreed to in writing from time to time by the Issuer, the Guarantors and the Trustee. The Trustee’s compensation shall not be limited by any law on compensation of a trustee of an express trust. The Issuer shall

-75-

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

(b)To secure the payment obligations of the Issuer and the Guarantors in this Section 7.6 the Trustee shall have a Lien prior to the Notes on all money or property held or collected by the Trustee, in its capacity as Trustee, other than money or property held in trust to pay principal of and interest, if any, on particular Notes.

(c)The Issuer’s payment obligations pursuant to this Section 7.6 shall survive the resignation or removal of the Trustee and the discharge of this Indenture. When the Trustee incurs expenses after the occurrence of a Default specified in Section 6.1(a)(7) with respect to the Issuer, the expenses are intended to constitute expenses of administration under the Bankruptcy Law.

SECTION 7.7 Replacement of Trustee.

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

(i)the Trustee is no longer eligible under Section 7.9;

-76-

(ii)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;

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

(iv)the Trustee otherwise becomes incapable of acting.

(b)If, with respect to the Notes, the Trustee resigns or has been removed by the Holders, Holders of a majority in principal amount of the outstanding Notes may appoint a successor Trustee with respect to the Notes. Otherwise, if the Trustee resigns or is removed (and such Holders do not reasonably promptly appoint a successor Trustee), or if a vacancy exists in the office of Trustee for any reason, the Issuer shall promptly appoint a successor Trustee. Within one year after the successor Trustee takes office, the Holders of a majority in aggregate principal amount of the then outstanding Notes may remove the successor Trustee to replace it with another successor Trustee appointed by the Issuer.

(c)A successor Trustee shall deliver a written acceptance of its appointment to the retiring Trustee and to the Issuer. Thereupon the resignation or removal of the retiring Trustee shall become effective, and the successor Trustee shall have all the rights, powers and duties of the Trustee under this Indenture. The successor Trustee shall send a notice of its succession to Holders of the Notes, and include in the notice its name and address of its corporate trust office. The retiring Trustee shall promptly transfer all property held by it as Trustee to the successor Trustee, subject to the Lien provided for in Section 7.6.

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

(e)If the Trustee fails to comply with Section 7.9, any Holder may petition any court of competent jurisdiction for the removal of the Trustee and the appointment of a successor Trustee with respect to the Notes.

(f)Notwithstanding the replacement of the Trustee pursuant to this Section 7.7, the Issuer’s obligations under Section 7.6 shall continue for the benefit of the retiring Trustee.

SECTION 7.8 Successor Trustee by Merger.

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

(b)In case at the time such successor or successors by merger, conversion or consolidation to shall succeed to the trusts created by this Indenture, any of the Notes shall have been authenticated but not delivered, any such successor to the Trustee may adopt the certificate

-77-

of authentication of any applicable predecessor Trustee, and deliver such Notes so authenticated; and in case at that time any of the Notes shall not have been authenticated, any successor to the Trustee may authenticate such Notes either in the name of any predecessor hereunder or in the name of the successor to the Trustee; and in all such cases such certificates shall have the full force which the Notes provide or this Indenture provides that the certificate of the Trustee shall have.

SECTION 7.9 Eligibility; Disqualification.

(a)There shall at all times be one or more Trustees under this Indenture, each of which (1) is a corporation organized and doing business under the laws of the United States or of any state or of the District of Columbia or a corporation or other person permitted to act as trustee by the SEC, (2) is authorized under such laws to exercise corporate trust powers, and (3) is subject to supervision or examination by federal, state, or District of Columbia authorities.

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

SECTION 7.10 Multiple Trustees.

(a)Notwithstanding anything to the contrary herein, any successor Trustee may be appointed with respect to the Notes; provided, however, that at any one time there shall be only one Trustee with respect to the Notes.

(b)In case of the appointment hereunder of a successor Trustee with respect to the Notes, every such successor Trustee so appointed shall execute, acknowledge and deliver to the Issuer and to the retiring Trustee an instrument accepting such appointment, and thereupon the resignation or removal of the retiring Trustee shall become effective and such successor Trustee, without any further act, deed or conveyance, shall become vested with all the rights, powers, trusts and duties of the retiring Trustee; but, on the request of the Issuer or the successor Trustee, such retiring Trustee shall, upon payment of its reasonable charges, if any, execute and deliver an instrument transferring to such successor Trustee all the rights, powers and trusts of the retiring Trustee and shall duly assign, transfer and deliver to such successor Trustee all property and money held by such retiring Trustee hereunder; subject, nevertheless, to its lien provided for in Section 7.6.

(c)Upon request of any such successor Trustee, the Issuer shall execute any and all instruments for more fully and certainly vesting in and confirming to such successor Trustee all such rights, powers and trusts referred to in Section 7.10(b). No successor Trustee with respect to the Notes shall accept its appointment unless at the time of such acceptance such successor Trustee shall be qualified and eligible with respect to the Notes under this Article.

SECTION 7.11 Limitation on Trustee’s Liability. Except as provided in this Article 7, in accepting the trusts hereby created, the entity acting as Trustee is not acting in its individual capacity and, except as provided in this Article 7, all Persons having any claim against the Trustee by reason of the transactions contemplated by this Indenture or any Note shall look only to the Issuer or a Guarantor for payment or satisfaction thereof.

(a)When (i) the Issuer delivers to the Trustee all outstanding Notes that have been authenticated (other than lost, stolen or destroyed Notes replaced or paid pursuant to the terms of this Indenture and Notes for which payment money has been deposited in trust and thereafter repaid to the Issuer) for cancellation or (ii) (A) all outstanding Notes not previously delivered to the Trustee for cancellation have become due and payable by reason of maturity, the giving of a notice of redemption or otherwise, will become due and payable within one year or may be called for redemption within one year under arrangements satisfactory to the Trustee for the giving of notice of redemption by the Trustee in the Issuer’s name and at the Issuer’s expense, and the Issuer has irrevocably deposited or caused to be deposited with the Trustee, as trust funds in trust solely for the benefit of the Holders, cash, U.S. Government Obligations, or a combination thereof, in such amounts as will be sufficient, in the opinion of a nationally recognized firm of independent public accountants, without consideration of any reinvestment of interest, to pay and discharge the entire Indebtedness on the Notes not theretofore delivered to the Trustee for cancellation for principal, premium, if any, and accrued interest to the date of maturity or redemption; (B) the Issuer has paid or caused to be paid all sums payable by it under this Indenture with respect to the Notes; and (C) the Issuer has delivered irrevocable instructions to the Trustee to apply the deposited money toward the payment of the Notes at maturity or the redemption date, as the case may be, then, this Indenture and all of the Issuer’s obligations in respect of the Notes shall, subject to Section 8.1(c), cease to be of further effect, and the Issuer shall be deemed to have satisfied and discharged this Indenture and all of its obligations in respect of the Notes. The Trustee shall acknowledge satisfaction and discharge of this Indenture on demand of the Issuer accompanied by an Officer’s Certificate and an Opinion of Counsel and at the cost and expense of the Issuer. For the avoidance of doubt, the Issuer will continue to be obligated to pay all other sums due under this Indenture to the Trustee.

(b)Subject to Sections 8.1(c) and 8.2, the Issuer at any time may terminate (i) all its obligations under the Notes and this Indenture (“legal defeasance option”) or (ii) its obligations with respect to the Notes under Article 4 (with the exception of Sections 4.1 and 4.3) and the operation of Section 6.1(a)(5)(B), Section 6.1(a)(6) and, with respect to Significant Subsidiaries and Subsidiary Guarantors, Section 6.1(a)(7) (“covenant defeasance option”). The Issuer may exercise its legal defeasance option with respect to the Notes notwithstanding its prior exercise of its covenant defeasance option with respect thereto. If the Issuer exercises its legal defeasance option with respect to the Notes, payment of the Notes may not be accelerated because of an Event of Default with respect to the Notes. If the Issuer exercises its covenant defeasance option with respect to the Notes, payment of the Notes may not be accelerated because of an Event of Default specified in Sections 6.1(a) (3), (4), (5), (6), (7) (with respect to Significant Subsidiaries) or (8). If the Issuer exercises its legal defeasance option or its covenant defeasance option with respect to the Notes, each Subsidiary Guarantor shall be released from all its obligations with respect to its Note Guarantee. Upon satisfaction of the conditions set forth herein and upon request of the Issuer, the Trustee shall acknowledge in writing the discharge of those obligations that the Issuer terminates.

-79-

(c)Notwithstanding clauses (a) and (b) above with respect to the Notes, the Issuer’s rights and obligations in Sections 2.3, 2.4, 2.5, 2.6, 2.8, 2.9, 2.10, 2.11, 2.12, 7.6, 7.7 and this Article 8 with respect to the Notes shall survive until the Notes have been paid in full, and, thereafter, the Issuer’s rights and obligations in Sections 7.6 and 8.4 shall survive.

SECTION 8.2 Conditions to Defeasance.

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

(i)the Issuer irrevocably deposits in trust (the “defeasance trust”) with the Trustee money or U.S. Government Obligations or a combination thereof (sufficient in the opinion of a nationally recognized certified public accounting firm) for the payment of principal and interest on the Notes to redemption or maturity;

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

(iii)no Default or Event of Default under this Indenture has occurred and is continuing after giving effect to such defeasance or covenant defeasance (other than a Default or Event of Default resulting from the borrowing of funds to be applied to such deposit and any simultaneous deposit relating to other indebtedness and, in each case, the granting of Liens in connection therewith);

(iv)the Issuer is not an insolvent, unable to pay its debts in full or on the eve of insolvency under applicable law on the date of such deposit;

(v)the Issuer shall have delivered to the Trustee an Opinion of Counsel to the effect that Holders and beneficial owners of the Notes will not recognize income, gain or loss for Federal income tax purposes as a result of such deposit and defeasance and will be subject to Federal income tax on the same amounts and in the same manner and at the same times as would have been the case if such deposit and defeasance had not occurred (and, in the case of legal defeasance only, such Opinion of Counsel shall be based on a ruling of the Internal Revenue Service or other change in applicable Federal income tax law);

(vi)the Issuer shall have delivered to the Trustee an Opinion of Counsel in the jurisdiction of organization of the Issuer to the effect that Holders and beneficial owners of the Notes will not recognize income, gain or loss for income tax purposes of such jurisdiction as a result of such deposit and defeasance and will be subject to income tax of such jurisdiction on the same

-80-

amounts and in the same manner and at the same times as would have been the case if such deposit and defeasance had not occurred; and

(vii)the Issuer delivers to the Trustee an Officer’s Certificate and an Opinion of Counsel, each to the effect that all conditions precedent to such defeasance or defeasance as contemplated by this Article 8 have been complied with.

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

SECTION 8.3 Application of Trust Money. The Trustee shall hold in trust money or U.S. Government Obligations deposited with it pursuant to this Article 8. It shall apply the deposited money and the money from U.S. Government Obligations through the Paying Agent and in accordance with this Indenture to the payment of principal of, interest (if any) and Additional Amounts (if any) on the Notes.

SECTION 8.4 Repayment to the Issuer. The Trustee and the Paying Agent shall promptly turn over to the Issuer upon request any money or U.S. Government Obligations held by it as provided in this Article which, in the written opinion of a nationally recognized firm of independent public accountants delivered to the Trustee (which delivery shall only be required if U.S. Government Obligations have been so deposited), are in excess of the amount thereof which would then be required to be deposited to effect an equivalent discharge or defeasance in accordance with this Article.

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

SECTION 8.5 Reinstatement. If the Trustee or Paying Agent is unable to apply any money or U.S. Government Obligations in accordance with this Article 8 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 obligations under this Indenture and the Notes shall be revived and reinstated as though no deposit had occurred pursuant to this Article 8 until such time as the Trustee or Paying Agent is permitted to apply all such money or U.S. Government Obligations in accordance with this Article 8; provided, however, that, if the Issuer has made any payment of interest on or principal of any Notes because of the reinstatement of its obligations, the Issuer shall be subrogated to the rights of the Holders of such Notes to receive such payment from the money or U.S. Government Obligations held by the Trustee or Paying Agent.

ARTICLE 9.

AMENDMENTS

SECTION 9.1 Without Consent of Holders.

(5)to add to the covenants of the Company, the Issuer or any Subsidiary Guarantor for the benefit of the Holders or to surrender any right or power conferred upon the Company, the Issuer or any Subsidiary Guarantor;

(9)to make any amendment to the provisions of this Indenture relating to the transfer and legending of Notes; provided, however, that (A) compliance with this Indenture as so amended would not result in Notes being transferred in violation of the Securities Act or any other applicable securities law and (B) such amendment does not materially and adversely affect the rights of Holders to transfer Notes except as required to satisfy any applicable requirements of the securities laws, including any exemption from registration thereunder;

-82-

(10)to evidence and provide for the acceptance and appointment under this Indenture of a successor Trustee thereunder pursuant to the requirements thereof; and

(11)to provide for the issuance of Additional Notes in accordance with the terms of this Indenture.

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

SECTION 9.2 With Consent of Holders; Waiver.

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

(1)reduce the amount of Notes whose Holders must consent to an amendment;

(2)reduce the rate of or extend the time for payment of interest on any Note;

(3)reduce the principal of or change the Stated Maturity of any Note;

(8)make any change in the ranking or priority of any Note or Note Guarantee that would adversely affect the Holders; or

(9)make any change in the provisions of Section 2.13 that adversely affects the rights of any Holder.

(b)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, but it shall be sufficient if such consent approves the substance thereof. For the avoidance of doubt, no amendment to, or deletion of any of the covenants contained in Article 4 (other than Section 4.1) shall be deemed to impair or affect any rights of Holders to institute suit for the enforcement of any payment on or with respect to, or to receive payment of principal of, or premium, if any, or interest on, the Notes.

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

SECTION 9.3 Revocation and Effect of Consents and Waivers.

(a)A consent to an amendment or a waiver by a Holder shall bind the Holder and every subsequent Holder of that Note or portion of the Note that evidences the same debt as the consenting Holder’s Note, even if notation of the consent or waiver is not made on the Note. However, any such Holder or subsequent Holder may revoke the consent or waiver as to such Holder’s Note or portion of the Note if the Trustee receives written notice of revocation at the Corporate Trust Office of the Trustee before the date the amendment or waiver becomes effective. After an amendment or waiver becomes effective, it shall bind every Holder. An amendment or waiver becomes effective upon the (i) receipt by the Issuer or the Trustee of the requisite number of consents, (ii) satisfaction of the conditions to effectiveness as set forth in this Indenture and any indenture supplemental hereto containing such amendment or waiver and (iii) execution of such amendment or waiver (or Guarantee Agreement) by the Issuer, the Company and the Trustee.

(b)The Issuer may, but shall not be obligated to, fix a record date for the purpose of determining the Holders entitled to give their consent or take any other action described above or required or permitted to be taken pursuant to this Indenture. If a record date is fixed, then notwithstanding the immediately preceding paragraph, those Persons who were Holders at such record date (or their duly designated proxies), and only those Persons, shall be entitled to give such consent or to revoke any consent previously given or to take any such action, whether or not such Persons continue to be Holders after such record date. No such consent shall be valid or effective for more than 90 days after such record date.

SECTION 9.4 Notation on or Exchange of Notes.

If an amendment changes the terms of a Note, the Trustee may require the Holder to deliver it to the Trustee. The Trustee may place an appropriate notation on the Note regarding the changed terms and return it to the Holder. Alternatively, if the Issuer or the Trustee so determines, the

-84-

Issuer in exchange for the Note shall issue and the Trustee shall authenticate a new Note that reflects the changed terms. Failure to make the appropriate notation or to issue a new Note shall not affect the validity of such amendment.

SECTION 9.5 Trustee To Sign Amendments, etc.

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

ARTICLE 10.

GUARANTEES

SECTION 10.1 Guarantees.

(a)The Company and each Subsidiary Guarantor hereby jointly and severally irrevocably and unconditionally guarantees to each Holder and to the Trustee and their respective successors and assigns (i) the full and punctual payment when due, whether at Stated Maturity, by acceleration, by redemption or otherwise, of all obligations of the Issuer under this Indenture (including obligations to the Trustee) and the Notes, whether for payment of principal of, or interest on the Notes and all other monetary obligations of the Issuer under this Indenture and the Notes and (ii) the full and punctual performance within applicable grace periods of all other obligations of the Issuer whether for fees, expenses, indemnification or otherwise under this Indenture and the Notes (all the foregoing being hereinafter collectively called the “Guaranteed Obligations”). Each Guarantor further agrees that the Guaranteed Obligations may be extended or renewed, in whole or in part, to the fullest extent permitted under applicable law, without notice or further assent from each such Guarantor, and that each such Guarantor shall remain bound under this Article 10 notwithstanding any extension or renewal of any Guaranteed Obligation.

(b)To the fullest extent permitted by applicable law, each Guarantor waives presentation to, demand of payment from and protest to the Issuer of any of the Guaranteed Obligations, notice of protest for nonpayment and notice of any default under the Notes or the Guaranteed Obligations. To the fullest extent permitted by applicable law, the obligations of each Guarantor hereunder shall not be affected by (i) the failure of any Holder or the Trustee to assert any claim or demand or to enforce any right or remedy against the Issuer or any other Person under this Indenture, the Notes or any other agreement or otherwise, (ii) any extension or renewal of any thereof, (iii) any rescission, waiver, amendment or modification of any of the terms or provisions of this Indenture, the Notes or any other agreement, (iv) the failure of any

-85-

Holder or Trustee to exercise any right or remedy against any other guarantor of the Guaranteed Obligations or (vi) any change in the ownership of such Guarantor.

(c)To the fullest extent permitted by applicable law, each Guarantor hereby waives any right to which it may be entitled (i) to have its obligations hereunder divided among the Guarantors, such that such Guarantor’s obligations would be less than the full amount claimed, (ii) to have the assets of the Issuer first be used and depleted as payment of the Issuer’s or such Guarantor’s obligations hereunder prior to any amounts being claimed from or paid by such Guarantor hereunder and (iii) to require that the Issuer be sued prior to an action being initiated against such Guarantor.

(d)Each Guarantor further agrees that its Guarantee herein constitutes a guarantee of payment, performance and compliance when due (and not a guarantee of collection) and waives any right to require that any resort be had by any Holder or the Trustee to any security held for payment of the Guaranteed Obligations.

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

Without limiting the generality of the foregoing, the obligations of each Guarantor herein shall not be discharged or impaired or otherwise affected by the failure of any Holder or the Trustee to assert any claim or demand or to enforce any remedy under this Indenture, the Notes or any other agreement, by any waiver or modification of any thereof, by any default, failure or delay, willful or otherwise, in the performance of the obligations, or by any other act or thing or omission or delay to do any other act or thing which may or might in any manner or to any extent vary the risk of any Guarantor or would otherwise operate as a discharge of any Guarantor as a matter of law or equity.

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

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

-86-

Guaranteed Obligations (but only to the extent not prohibited by law) and (iii) all other monetary obligations of the Issuer to the Holders and the Trustee.

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

(i)Each Guarantor also agrees to pay any and all costs and expenses (including reasonable attorneys’ fees and expenses) incurred by the Trustee or any Holder in enforcing any rights under this Section 10.1.

(j)The obligations and liabilities of any guarantor incorporated in Norway in its capacity as a guarantor (each a “Norwegian Guarantor”) shall not cover any indebtedness or liability which, if they did so extend, would cause an infringement of Section 8-10 and/or Section 8-7 cf. Section 1-3, or any of the other provisions in chapter 8 III, of the Norwegian Private Limited Companies Act 1997 (the “Norwegian Companies Act” regulating unlawful financial assistance and other prohibited loans, guarantees and joint and several liability as well as providing of security, and it is understood and agreed that the liability of any Norwegian Guarantor only applies to the extent permitted by the above-mentioned provisions of the Norwegian Companies Act. Under no circumstances shall the obligations and liabilities of any Norwegian Guarantor cover the debt and/or other liabilities incurred in respect of the purchase of the shares in any of such Norwegian Guarantor’s Holding.

(k)For each Guarantor incorporated in Switzerland (a “Swiss Guarantor”):

(1)If and to the extent (x) the Guarantee under this Article 10 or any other indemnity by a Swiss Guarantor under this Indenture or the Notes guarantees or indemnifies obligations of its (direct or indirect) parent companies (upstream security) or sister companies (cross-stream security) (the “Upstream or Cross-Stream Guaranteed Obligations”) and (y) using payments under this Indenture or the Notes to discharge the Upstream or Cross-Stream Guaranteed Obligations would constitute a repayment of capital (Einlagerückgewähr/Kapitalrückzahlung), a violation of the legally protected reserves (gesetzlich geschützte Reserven) or the payment of a (constructive) dividend (Gewinnausschüttung) under Swiss corporate law, the payments under this Indenture and the Notes shall be limited to the maximum amount of the Swiss Guarantor’s freely disposable shareholder equity at the time of enforcement (the “Maximum Amount”); provided that such limitation is required under the applicable law at that time;

-87-

provided, further, that such limitation shall not free the Swiss Guarantor from its obligations in excess of the Maximum Amount, but merely postpone the performance date of those obligations until such time or times as performance is again permitted under then applicable law. This Maximum Amount of freely disposable shareholder equity shall be determined in accordance with Swiss law and applicable Swiss accounting principles, and, if and to the extent required by applicable Swiss law, shall be confirmed by the auditors of the Swiss Guarantor on the basis of an interim audited balance sheet as of that time.

(2)In respect of Upstream or Cross-Stream Guaranteed Obligations, at the time it is required to make a payment under this Indenture or the Notes, the Swiss Guarantor shall, if and to the extent required by applicable law in force at the relevant time:

(A)use its best efforts to ensure that payment can be used to discharge Upstream or Cross-Stream Guaranteed Obligations without deduction of any taxes imposed under the Swiss Federal Act on the Withholding Tax (Bundesgesetz über die Verrechnungssteuer) of October 13, 1965, as amended from time to time (SR 642.21), together with the related ordinances, regulations and guidelines, all as amended and applicable from time to time (“Swiss Withholding Tax”) by discharging such tax liability by notification pursuant to applicable law rather than payment of the tax;

(B)if the notification procedure pursuant to sub-clause (i) above does not apply, deduct the Swiss Withholding Tax at such rate (currently 35% at the date of this Indenture) as is in force from time to time from any such payment used to discharge Upstream or Cross-Stream Guaranteed Obligations; or deduct Swiss Withholding Tax at the reduced rate resulting after discharge of part of such tax by notification if the notification procedure pursuant to sub clause (i) above applies for a part of Swiss Withholding Tax only, and pay, without delay, any such taxes deducted to the Swiss Federal Tax Administration;

(C)notify the Trustee that such notification or, as the case may be, deduction has been made, and provide the Trustee with evidence that such notification of the Swiss Federal Tax Administration has been made or, as the case may be, such taxes deducted have been paid to the Swiss Federal Tax Administration; and

-88-

(D)in the case of a deduction of Swiss Withholding Tax, use its best efforts to ensure that any Person, which is entitled to a full or partial refund of the Swiss Withholding Tax deducted from such payment, will, as soon as possible after such deduction,

(1)request a refund of the Swiss Withholding Tax under applicable law (including tax treaties), and

(2)pay to the Trustee upon receipt any amount so refunded.

(3)The Swiss Guarantor shall promptly take and promptly cause to be taken any action, including the following:

(A)the passing of any shareholders’ resolutions to approve the payment or other performance under this Article 10, which may be required as a matter of mandatory Swiss law in force at the time of the enforcement of the Guarantees or any other indemnity in order to allow a prompt payment;

(B)preparation of an up-to-date audited balance sheet of the Swiss Guarantor;

(C)confirmation of the auditors of the Swiss Guarantor that the relevant amount represents the Maximum Amount;

(D)conversion of restricted reserves into profits and reserves freely available for distribution as dividends (to the extent permitted by mandatory Swiss law);

(E)revaluation of hidden reserves (to the extent permitted by mandatory Swiss law);

(F)to the extent permitted by applicable law, Swiss accounting standards, and this Indenture and the Notes, write-up or realize any of its assets that are shown in the Swiss Guarantor’s balance sheet with a book value that is significantly lower than the market value of the assets, in case of realization, however, only if such assets are not necessary for the Swiss Guarantor’s business (nicht betriebsnotwendig); and

(G)all such other measures necessary or useful to allow the Swiss Guarantor to make payments as agreed hereunder with a minimum of limitations.

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

-89-

SECTION 10.2 Limitation on Liability.

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

SECTION 10.3 Successors and Assigns.

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

SECTION 10.4 No Waiver.

Neither a failure nor a delay on the part of either the Trustee or the Holders in exercising any right, power or privilege under this Article 10 shall operate as a waiver thereof, nor shall a single or partial exercise thereof preclude any other or further exercise of any right, power or privilege. The rights, remedies and benefits of the Trustee and the Holders herein expressly specified are cumulative and not exclusive of any other rights, remedies or benefits which either may have under this Article 10 at law, in equity, by statute or otherwise.

SECTION 10.5 Modification.

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

SECTION 10.6 Release of Subsidiary Guarantor.

(a)The Note Guarantee of a Subsidiary Guarantor will be automatically released and discharged:

(1)upon such Subsidiary Guarantor becoming an Excluded Subsidiary to the extent not prohibited by this Indenture;

(2)upon the release or discharge of such Subsidiary Guarantor as borrower or guarantor (as applicable) of, and of all Liens, if any, granted by such subsidiary in connection with the Amended Revolving Credit Agreement

-90-

and any other Indebtedness that required such Subsidiary Guarantor to enter into a supplemental indenture to provide a Note Guarantee pursuant to Section 10.7, other than if such Subsidiary Guarantor would otherwise be required to enter into a supplemental indenture to provide a Note Guarantee pursuant to such Section 10.7 immediately upon such release;

(3)upon any sale, exchange, disposition, issuance or transfer (including by merger, amalgamation, consolidation or otherwise) of:

(A)the Equity Interests of such Subsidiary Guarantor or any holder of Equity Interests of such Subsidiary Guarantor, after which the applicable Subsidiary Guarantor is no longer a subsidiary of the Company, or

(B)all or substantially all the assets of such Subsidiary Guarantor;

(4)upon the designation of such Subsidiary Guarantor as an Unrestricted Subsidiary in compliance with Section 4.7;

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

(6)upon the Issuer’s exercise of its legal defeasance option or its covenant defeasance option under Article 8 or if the Issuer’s obligations under this Indenture are discharged in accordance with the terms hereof.

(b)A Subsidiary Guarantor may consolidate with, merge with or into, or liquidate or dissolve into, or transfer all or substantially all its assets to, any other Person to the extent set forth in Article 5, and upon completion of such a transaction in compliance with such Article 5, the Note Guarantee of such Subsidiary Guarantor will be automatically released and discharged.

SECTION 10.7 Execution of Guarantee Agreement for Future Subsidiary Guarantors.

The Company and the Issuer will cause each subsidiary of the Company that is a Restricted Subsidiary and not a Subsidiary Guarantor that (i) becomes a borrower or guarantor under the Amended Revolving Credit Agreement or (ii) that Guarantees on the Issue Date or at any time thereafter, any other Indebtedness of the Company, the Issuer or any Subsidiary Guarantor under Credit Facilities that exceeds $150 million in aggregate principal amount, to execute and deliver to the Trustee within 30 days a Guarantee Agreement; provided, however, that, a Restricted Subsidiary shall not be required to Guarantee the Notes if such Restricted Subsidiary is an Excluded Subsidiary.

-92-

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

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

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

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

SECTION 11.2 Trustee Instructions.

The Trustee shall have the right to accept and act upon instructions, including funds transfer instructions (“Instructions”) given pursuant to this Indenture and delivered using Electronic Means; provided, however, that the Issuer and/or the Company, as applicable, shall provide to the Trustee an incumbency certificate listing officers with the authority to provide such Instructions (“Authorized Officers”) and containing specimen signatures of such Authorized Officers, which incumbency certificate shall be amended by the Issuer and/or the Company, as applicable, whenever a person is to be added or deleted from the listing. If the Issuer and/or the Company, 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 and the Company 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 and the Company shall be responsible for ensuring that only Authorized Officers transmit such Instructions to the Trustee and that the Issuer and the Company, as applicable, 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 and/or the Company, as applicable. The Trustee shall not be liable for any losses, costs or expenses arising directly or indirectly from the Trustee’s reliance upon and compliance with such Instructions notwithstanding such directions conflict or are inconsistent with a subsequent written instruction. The Issuer and the Company 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 and/or the Company, as applicable; (iii) that the security procedures (if any) to be followed in connection with its transmission of Instructions provide to it a commercially

-93-

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.

SECTION 11.3 Certificate and Opinion as to Conditions Precedent.

Upon any request or application by the Issuer to the Trustee to take or refrain from taking any action under this Indenture (except for authentication of the Notes by the Trustee on the Issue Date, which shall not require an Opinion of Counsel), the Issuer shall furnish to the Trustee:

(a)an Officer’s Certificate in form and substance reasonably satisfactory to the Trustee (which shall include the statements set forth in Section 11.4) to the effect that, in the opinion of the signers, all conditions precedent and covenants, if any, provided for in this Indenture relating to the proposed action have been complied with; and

(b)an Opinion of Counsel in form and substance reasonably satisfactory to the Trustee (which shall include the statements set forth in Section 11.4) to the effect that, in the opinion of such counsel, all such conditions precedent and covenants have been complied with.

SECTION 11.4 Statements Required in Certificate or Opinion.

Each certificate or opinion with respect to compliance with a covenant or condition provided for in this Indenture shall include:

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

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

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

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

SECTION 11.5 When Notes Disregarded.

In determining whether the Holders of the required principal amount of Notes have concurred in any direction, waiver or consent, Notes owned by the Issuer, 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 shall be disregarded and deemed not to be outstanding, except that, for the purpose of determining whether the Trustee shall be protected in relying on any such direction, waiver or consent, only Notes which the Trustee knows are so owned shall be so disregarded. Also, subject to the foregoing, only Notes outstanding at the time shall be considered in any such determination.

-94-

SECTION 11.6 Rules by Trustee, Paying Agent and Registrar.

The Trustee may make reasonable rules for action by or a meeting of Holders. The Trustee, the Registrar or the Paying Agent may make reasonable rules for their functions.

SECTION 11.7 Business Days.

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

SECTION 11.8 Governing Law.

This Indenture and the Notes shall be governed by, and construed in accordance with, the laws of the State of New York.

SECTION 11.9 No Recourse Against Others.

A past, present or future director, officer, employee, incorporator, member, partner or stockholder, as such, of the Issuer or any Guarantor, or of any stockholder of the Issuer or any Guarantor, shall not have any liability for any obligations of the Issuer or any Guarantor, either directly or through the Issuer or any Guarantor, as the case may be, under the Notes, Note Guarantees or this Indenture or for any claim based on, in respect of or by reason of such obligations or their creation whether by virtue of any rule of law, statute or constitutional provision or by the enforcement of any assessment or by any legal or equitable proceeding or otherwise. By accepting a Note, each Holder shall waive and release any and all such liability. The waiver and release shall be part of the consideration for the issue of the Notes.

SECTION 11.10 Successors.

All agreements of the Issuer and any Guarantor in this Indenture and the Notes shall bind their respective successors. All agreements of the Trustee in this Indenture shall bind its successors.

SECTION 11.11 Multiple Originals.

The parties may sign any number of copies of this Indenture. Each signed copy shall be an original, but all of them together represent the same agreement. The exchange of copies of this Indenture and of signature pages by PDF or other electronic transmission shall constitute effective execution and delivery of this Indenture as to the parties hereto and may be used in lieu of the original Indenture for all purposes. Signatures of all the parties hereto transmitted by PDF or other electronic means shall be deemed to be their original signatures for all purposes other than the Trustee’s signature on the certificate of authentication on each Note. Unless otherwise provided herein, the words “execute,” “execution,” “signed” and “signature” and words of similar import used in or related to any document to be signed in connection with this Indenture or any of the transactions contemplated hereby (including amendments, waivers, consents and other modifications) shall be deemed to include electronic signatures and the keeping of records in electronic form, each of which shall be of the same legal effect, validity or enforceability as a manually executed signature in ink or the use of a paper-based recordkeeping system, as

-95-

applicable, to the fullest extent and as provided for in any applicable law, including the Federal Electronic Signatures in Global and National Commerce Act, the New York State Electronic Signatures and Records Act and any other similar state laws based on the Uniform Electronic Transactions Act; provided that, notwithstanding anything herein to the contrary, the Trustee is under no obligation to agree to accept electronic signatures in any form or in any format unless expressly agreed to by the Trustee pursuant to reasonable procedures approved by the Trustee.

SECTION 11.12 Table of Contents; Headings.

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

SECTION 11.13 WAIVER OF TRIAL BY JURY.

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

SECTION 11.14 Force Majeure.

In no event shall the Trustee be responsible or liable for any failure or delay in the performance of its obligations hereunder arising out of or caused by, directly or indirectly, forces beyond its control, including, without limitation, strikes, work stoppages, accidents, acts of war or terrorism, civil or military disturbances, nuclear or natural catastrophes or acts of God, and interruptions, loss or malfunctions of utilities, communications or computer (software and hardware) services; it being understood that the Trustee shall use reasonable efforts that are consistent with accepted practices in the banking industry to resume performance as soon as practicable under the circumstances.

SECTION 11.15 USA Patriot Act Compliance.

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

-96-

SECTION 11.16 Submission to Jurisdiction.

Each of the Issuer and each Subsidiary Guarantor not organized in the United States hereby appoints the Company as its agent for service of process in any suit, action or proceeding with respect to this Indenture, the Notes and the Note Guarantees and for actions brought under the U.S. federal or state securities laws brought in any U.S. federal or state court located in the Borough of Manhattan in the County and City of New York. The Company hereby acknowledges and accepts its appointment by the Issuer and each Subsidiary Guarantor not organized in the United States. Such service may be made by mailing or delivering a copy of such process to the Issuer or such Subsidiary Guarantor not organized in the United States in care of the Company at its address as specified in Section 11.1 of this Indenture (or such other address as provided in a written notice to the Trustee). The Company, the Issuer and each Subsidiary Guarantor irrevocably and unconditionally submit to the exclusive jurisdiction of the U.S. federal or state courts sitting in the Borough of Manhattan in the County and City of New York over any suit, action or proceeding arising out of or relating to this Indenture, the Notes or the Note Guarantees and for actions brought under the U.S. federal or state securities laws. Service of any process on the Company in any such action (and written notice of such service to the Issuer) shall be effective service of process against the Issuer or any Guarantor with respect to any such suit, action or proceeding. The Company, the Issuer and each Subsidiary Guarantor irrevocably and unconditionally waive any objection to the laying of venue of any such suit, action or proceeding brought in any such court and any claim that any such suit, action or proceeding has been brought in an inconvenient forum. A final judgment in any such suit, action or proceeding brought in any such court shall be conclusive and binding upon the Company, the Issuer and each Subsidiary Guarantor and may be enforced in any other courts to whose jurisdiction the Issuer is or may be subject, by suit upon judgment. The Company, the Issuer and each Subsidiary Guarantor further agree that nothing herein shall affect any Holder’s right to effect service of process in any other manner permitted by law or bring a suit action or proceeding (including a proceeding for enforcement of a judgment) in any other court or jurisdiction in accordance with applicable law.

SECTION 11.17 Waiver of Immunity.

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

-97-

SECTION 11.18 Conversion of Currency.

If for the purposes of obtaining judgment in any court it is necessary to convert a sum due under this Indenture to the Holder from U.S. dollars to another currency, the Issuer and each Guarantor agree, and each Holder by holding such Note will be deemed to have agreed, to the fullest extent that the Issuer, each Guarantor and they may effectively do so, that the rate of exchange used shall be that at which in accordance with normal banking procedures such Holder could purchase U.S. dollars with such other currency in New York City, New York on the Business Day preceding the day on which final judgment is given.

The Issuer’s and Guarantors’ obligations to any Holder will, notwithstanding any judgment in a currency (the “Judgment Currency”) other than U.S. dollars, be discharged only to the extent that on the Business Day following receipt by such Holder or the Trustee, as the case may be, of any amount in such Judgment Currency, such Holder may in accordance with normal banking procedures purchase U.S. dollars with the Judgment Currency. If the amount of the U.S. dollars so purchased is less than the amount originally to be paid to such Holder or the Trustee in the Judgment Currency (as determined in the manner set forth in the preceding paragraph), as the case may be, each of the Issuer and the Guarantors, jointly and severally, agrees, as a separate obligation and notwithstanding any such judgment, to indemnify the Holder and the Trustee, as the case may be, against any such loss. If the amount of the U.S. dollars so purchased is more than the amount originally to be paid to such Holder or the Trustee, as the case may be, such Holder or the Trustee, as the case may be, will pay the Issuer and the Guarantors, such excess; provided that such Holder or the Trustee, as the case may be, shall not have any obligation to pay any such excess as long as a Default under the Notes or this Indenture has occurred and is continuing or if the Issuer or the Guarantors shall have failed to pay any Holder or the Trustee any amounts then due and payable under the Notes or this Indenture, in which case such excess may be applied by such Holder or the Trustee to such obligations.

SECTION 11.19 FATCA

The Paying Agent shall be entitled to deduct or withhold from payments under this Indenture to the extent necessary to comply with an agreement described in Section 1471(b) of the Code or otherwise imposed pursuant to FATCA. To the extent permitted under applicable privacy law and if expressly authorized by any agreement between the Issuer and such holder or beneficial owner or by the terms of any tax certification, the Issuer hereby covenants with the Trustee that it will use commercially reasonable efforts to provide the Trustee with any relevant tax certification in the possession of the Issuer or other information identified by the Issuer in its sole discretion as relevant for FATCA withholding tax purposes that may be useful to assist the Trustee to determine whether or not the Trustee is obliged, in respect of any payments to be made by it pursuant to this Indenture, to make any withholding or deduction pursuant to FATCA.

6.875% Senior Note due 2036 (the “Notes”)

1.Interest

ALCOA NEDERLAND HOLDING B.V., a besloten vennootschap met beperkte aansprakelijkheid incorporated under the laws of The Netherlands (such company, and its successors and assigns under the Indenture hereinafter referred to, being herein called the “Issuer”), promises to pay interest on the principal amount of this Note at the rate per annum shown above. The Issuer shall pay interest semiannually on March 31 and September 30 of each year. Interest on the Notes shall accrue from the most recent date to which interest has been paid or duly provided for or, if no interest has been paid or duly provided for, from September 23, 2026 until the principal hereof is due. Interest shall be computed on the basis of a 360-day year of twelve 30-day months.

2.Method of Payment

The Issuer shall pay interest on the Notes (except defaulted interest) to the Persons who are registered Holders at the close of business on the March 15 or September 15 next preceding the interest payment date; provided that for so long as the Notes are held by DTC, the Issuer shall pay interest on the Notes to the Persons who are registered Holders at the close of business on the Business Day immediately preceding the applicable interest payment date. The Issuer shall pay interest on the Notes on each interest payment date even if Notes are canceled after the record date and on or before the interest payment date. Holders must surrender Notes to a Paying Agent to collect principal payments. The Issuer shall pay principal, premium, if any, and interest in money of the United States of America that at the time of payment is legal tender for payment of public and private debts. Cash payments of principal of, premium, if any, and interest on the Notes are payable at the office or agency of the Issuer maintained for such purpose or, at the option of the Issuer, cash payment of interest may be made by check mailed to the Holders at their respective addresses or transmitted by wire in accordance with wiring instructions set forth in the register of Holders; provided, that (1) all cash payments of principal, premium, if any, and interest with respect to Global Notes registered in the name of or held by DTC or its nominee will be made by wire transfer of immediately available funds to the accounts specified by the registered Holder or Holders thereof and (2) all cash payments of principal, premium, if any, and interest with respect to certificated Notes will be made by wire transfer to a U.S. dollar account maintained by the payee with a bank in the United States if such Holder elects payment by wire transfer by giving written notice to the Trustee or the Paying Agent to such effect designating such account no later than 30 days immediately preceding the relevant due date for payment (or such other date as the Trustee may agree). Until otherwise designated by the Issuer, the Issuer’s office or agency is the office of the Trustee maintained for such purpose. If a payment date falls on a day that is not a Business Day, payment will be made on the next succeeding Business Day and no interest shall accrue for the intervening period.

A-6

3.Paying Agent and Registrar

Initially, The Bank of New York Mellon Trust Company, N.A. (the “Trustee”), shall act as Paying Agent and Registrar. The Issuer may appoint and change any Paying Agent or Registrar without notice. The Issuer or any of its wholly owned subsidiaries organized under the laws of the United States or any state thereof may act as Paying Agent (prior to an Event of Default), Registrar, co-registrar or transfer agent.

4.Indenture

The Issuer issued the Notes under an Indenture dated as of September 23, 2026 (the “Indenture”), among the Issuer, Alcoa Corporation (the “Company”), a Delaware corporation, the Subsidiary Guarantors party thereto and the Trustee. Terms defined in the Indenture and not defined herein have the meanings ascribed thereto in the Indenture. The Notes are subject to all terms and provisions of the Indenture and Holders are referred to the Indenture for a statement of such terms and provisions.

The Notes are senior unsecured obligations of the Issuer. The Issuer shall be entitled to issue Additional Notes pursuant to Section 2.15 of the Indenture. The Original Notes and any Additional Notes shall be treated as a single class for all purposes of the Indenture. The Indenture imposes certain limitations on the ability of the Company, the Issuer and certain of their subsidiaries to, among other things, create liens on certain assets to secure debt and enter into certain sale and leaseback transactions. The Indenture also imposes limitations on the ability of the Company, the Issuer and the Subsidiary Guarantors to consolidate, amalgamate or merge with or into any other Person or convey, transfer or lease all or substantially all their property.

To guarantee the due and punctual payment of the principal of, and interest on the Notes and all other amounts payable by the Issuer under the Indenture and the Notes when and as the same shall be due and payable, whether at maturity, by acceleration or otherwise, according to the terms of the Notes and the Indenture, the Company and the Subsidiary Guarantors have unconditionally guaranteed the Guaranteed Obligations on a senior unsecured basis pursuant to the terms of the Indenture. Certain other subsidiaries of the Company will be required to guarantee the Guaranteed Obligations on or after the Issue Date, subject to the limitations set forth in the Indenture.

5.Optional Redemption

Except as set forth in this Section 5, the Issuer shall not be entitled to redeem the Notes at its option.

(a) Prior to September 30, 2031, the Issuer will be entitled at its option to redeem all, but not less than all, of the Notes, upon not less than 10 nor more than 60 days’ notice, at a redemption price equal to 100% of the principal amount of the Notes plus the Applicable Premium as of, and accrued and unpaid interest to but not including, the redemption date (subject to the right of Holders of record on the relevant record date to receive interest due on the relevant interest payment date).

A-7

On and after September 30, 2031, the Issuer will be entitled at its option to redeem on one or more occasions all or a portion of the Notes, upon not less than 10 nor more than 60 days’ notice, at the redemption prices set forth below (expressed in percentages of principal amount on the redemption date), plus, in each case, accrued interest to but not including the redemption date (subject to the right of Holders of record on the relevant record date to receive interest due on the relevant interest payment date), if redeemed during the 12-month period commencing on September 30 of the years set forth below:

2031	103.438%
2032	101.719%
2033 and thereafter	100.000%

(b) In addition, at any time prior to September 30, 2029, the Issuer will be entitled at its option on one or more occasions to redeem the Notes, upon not less than 10 nor more than 60 days’ notice, in an aggregate principal amount not to exceed 40% of the aggregate principal amount of the Notes originally issued at a redemption price (expressed as a percentage of principal amount) of 106.875%, plus accrued and unpaid interest to but not including the redemption date (subject to the right of Holders of record on the relevant record date to receive interest due on the relevant interest payment date), if the principal and premium for such redemption is paid with the net cash proceeds from one or more Qualified Equity Offerings; provided, however, that

(1)at least 60% of the original aggregate principal amount of Notes remains outstanding immediately after the occurrence of each such redemption (other than Notes held, directly or indirectly, by the Company or its Affiliates); and

(2)each such redemption occurs within 180 days after the date of the related Qualified Equity Offering.

(c) The Issuer is also entitled to redeem the Notes, at its option, at any time as a whole but not in part, upon not less than 15 nor more than 60 days’ notice, at 100% of the principal amount thereof on the date of redemption, plus accrued and unpaid interest, if any, to, but not including, the date of redemption (subject to the right of Holders of record on the relevant record date to receive interest due on the relevant interest payment date), in the event the Issuer, the Company or any Subsidiary 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:

(1)a change in or an amendment to the laws (including any regulations promulgated thereunder) of a Relevant Taxing Jurisdiction (or any political subdivision or taxing authority thereof or therein) or the official entry or any change in the official application or interpretation of such laws or regulations; or

(2)any change in or amendment to any official position regarding the application or interpretation of such laws or regulations,

A-8

which change or amendment is announced or becomes effective on or after the Issue Date (or, if the Relevant Taxing Jurisdiction has changed since the Issue Date, the date on which such jurisdiction became a Relevant Taxing Jurisdiction) and it cannot avoid such obligation by taking reasonable measures available to it.

Before the Issuer delivers notice of redemption of the Notes as described above in this Section 5(c), it will deliver to the Trustee an Officer’s Certificate to the effect that it cannot avoid its obligation to pay Additional Amounts by taking reasonable measures available to it. The Issuer will also deliver an opinion of independent legal counsel of recognized standing stating that it would be obligated to pay Additional Amounts as a result of a change in tax laws or regulations or the application or interpretation of such laws or regulations.

(d) If Holders of not less than 90% in aggregate principal amount of the outstanding Notes validly tender and do not withdraw such Notes in a Change of Control Offer and the Issuer, or any third party making a Change of Control Offer in lieu of the Issuer as described in the Indenture, purchases all of the Notes validly tendered and not withdrawn by such Holders, the Issuer or such third party will have the right, upon not less than 15 days’ nor more than 60 days’ prior notice (provided that such notice is given not more than 30 days following such purchase pursuant to the Change of Control Offer described in the Indenture) to redeem all Notes that remain outstanding following such purchase at a price in cash equal to 101% of the principal amount thereof on the redemption date plus accrued and unpaid interest (if any) to but not including the redemption date (subject to the right of Holders of record on the relevant record date to receive interest due on the relevant interest payment date).

(e) Any optional redemption of the Notes under this Section 5 may, at the Issuer’s discretion, be subject to one or more conditions precedent, including completion of a Qualified Equity Offering, refinancing transaction or other corporate transaction. In addition, if such redemption or notice is subject to satisfaction of one or more conditions precedent, such notice shall state that, in the Issuer’s discretion, the redemption date may be delayed until such time as any or all of such conditions shall be satisfied (or waived by the Issuer in its sole discretion), or such redemption may not occur and such notice may be rescinded in the event that any or all such conditions shall not have been satisfied (or waived by the Issuer in its sole discretion) by the redemption date, or by the redemption date so delayed, and the redemption of the notes shall be rescinded or delayed as provided in such notice. If any condition precedent has not been satisfied, the Issuer will provide written notice to the Trustee prior to the close of business on the Business Day prior to the redemption date. Upon receipt of such notice, the notice of redemption shall be rescinded and the redemption of the Notes shall not occur or, if specified in such notice, the date of such redemption shall be extended to the specified date, which shall not be later than the latest date upon which such redemption is permitted to occur under this Section 5. Upon receipt, the Trustee shall provide such notice to each Holder of the Notes in the same manner in which the notice of redemption was given.

(f) The Notes are subject to Special Mandatory Redemption provisions as provided in Section 3.9 of the Indenture.

6.Sinking Fund

The Notes are not subject to any sinking fund.

A-9

7.Notice of Redemption

Notice of any redemption pursuant to Section 5(a) or (b) above shall be mailed by first-class mail (or otherwise delivered in accordance with the Applicable Procedures) at least 10 days but not more than 60 days before the redemption date to each Holder of Notes to be redeemed at his or her registered address and notice of any redemption pursuant to Section 5(c) or (d) above shall be mailed by first-class mail (or otherwise delivered in accordance with the Applicable Procedures) at least 15 days but not more than 60 days before the redemption date to each Holder of Notes to be redeemed at his or her registered address, except that, in each case, redemption notices may be mailed (or otherwise delivered in accordance with the Applicable Procedures) more than 60 days prior to the redemption date if the notice is issued in connection with a defeasance of the Notes or a satisfaction and discharge of the Indenture. Any inadvertent defect in the notice of redemption, including an inadvertent failure to give notice, to any Holder selected for redemption shall not impair or affect the validity of the redemption of any other Note redeemed in accordance with provisions of the Indenture. Notes in denominations of $200,000 or less may be redeemed in whole but not in part.

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

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

In accordance with Section 4.6 of the Indenture, the Issuer shall be required to offer to purchase Notes upon the occurrence of a Change of Control Repurchase Event. Any Holder of Notes shall have the right, subject to certain conditions specified in the Indenture, to cause the Issuer to repurchase all or any part of the Notes of such Holder at a purchase price equal to 101% of the principal amount of the Notes to be repurchased plus accrued and unpaid interest, if any, to, but excluding, the date of repurchase (subject to the right of Holders of record on the relevant record date to receive interest due on the relevant interest payment date) as provided in, and subject to the terms of, the Indenture.

9.Denominations; Transfer; Exchange

The Notes are in registered form without coupons in denominations of $200,000 and whole multiples of $1,000 in excess thereof. A Holder may transfer or exchange Notes in accordance with the Indenture. Upon any transfer or exchange, the Registrar and the Trustee may require a Holder, among other things, to furnish appropriate endorsements or transfer documents and to pay any taxes required by law or permitted by the Indenture. The Issuer need

A-10

not transfer or exchange any Note selected for redemption or tendered (and not withdrawn) for repurchase in connection with a Change of Control Offer, need not issue, register the transfer of or exchange any Note during the period of 15 days before the sending of a notice of redemption of Notes to be redeemed and need not register the transfer or exchange of any Note during the period of 15 days prior to an interest payment date.

10.Persons Deemed Owners

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

11.Unclaimed Money

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

12.Discharge and Defeasance

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

13.Amendment, Supplement and Waiver

Subject to certain exceptions, the Indenture may be amended 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 for the Notes) and any past default or compliance with any provisions may also be waived 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 for the Notes). However, without the consent of each Holder of an outstanding Note affected thereby, an amendment or waiver may not, among other things:

(1)reduce the amount of Notes whose Holders must consent to an amendment;

(2)reduce the rate of or extend the time for payment of interest on any Note;

(3)reduce the principal of or change the Stated Maturity of any Note;

(4)change the provisions applicable to the redemption of any Note as provided under Article 3, other than minimum or maximum notice requirements;

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

A-11

(6)modify the contractual right of a Holder to bring suit for the payment of principal, interest or premium (if any) on the Notes held by such Holder, on or after the respective due dates, including by modifying Section 6.7 of the Indenture;

(7)make any change in the amendment or waiver provisions which require each Holder’s consent as described in Sections 9.2(a)(1) through (6) or Sections 9.2(a)(8) and (9) of the Indenture;

(8)make any change in the ranking or priority of any Note or Note Guarantee that would adversely affect the Holders; or

(9)make any change in the provisions of Section 2.13 of the Indenture that adversely affects the rights of any Holder.

Notwithstanding the preceding, without the consent of any Holder, the Company, the Issuer and the Subsidiary Guarantors and the Trustee may amend the Indenture:

(1)to cure any ambiguity, omission, defect or inconsistency in the Indenture;

(2)to provide for the assumption by a successor entity of the obligations of the Company, the Issuer or any Subsidiary Guarantor under the Indenture;

(3)to provide for uncertificated Notes in addition to or in place of certificated Notes (provided that the uncertificated Notes are issued in registered form for purposes of Section 163(f) of the Code);

(4)to add Guarantees with respect to the Notes, including any Subsidiary Guarantee, or to secure the Notes;

(5)to add to the covenants of the Company, the Issuer or any Subsidiary Guarantor for the benefit of the Holders or to surrender any right or power conferred upon the Company, the Issuer or any Subsidiary Guarantor;

(6)to make any change that does not adversely affect the rights of any Holder in any material respect;

(7)to comply with any requirement of the SEC in connection with the qualification of the Indenture under the Trust Indenture Act;

(8)to conform the text of the Indenture, the Notes or any Note Guarantee to any provision of the “Description of Notes” in the Offering Memorandum, as determined in good faith by the Company;

(9)to make any amendment to the provisions of the Indenture relating to the transfer and legending of Notes; provided, however, that (A) compliance with the Indenture as so amended would not result in Notes being transferred in violation of the Securities Act or any other applicable

A-12

securities law and (B) such amendment does not materially and adversely affect the rights of Holders to transfer Notes except as required to satisfy any applicable requirements of the securities laws, including any exemption from registration thereunder;

(10)to evidence and provide for the acceptance and appointment under the Indenture of a successor Trustee thereunder pursuant to the requirements thereof; and

(11)to provide for the issuance of Additional Notes in accordance with the terms of the Indenture.

14.Defaults and Remedies

Under the Indenture, each of the following is an Event of Default:

(1)a default in the payment of interest on the Notes when due, continued for 30 days;

(2)a default in the payment of principal of any Note when due at its Stated Maturity, upon redemption, upon required purchase, upon declaration of acceleration or otherwise, including the failure to consummate the Special Mandatory Redemption to the extent required by Section 3.9 of the Indenture;

(3)the failure by the Company, the Issuer or any Subsidiary Guarantor to comply with its obligations under Section 5.1 of the Indenture regarding certain mergers and consolidations;

(4)the failure by the Company, the Issuer or any Subsidiary Guarantor to comply for 60 days after notice with any of its obligations, covenants or other agreements under the Indenture or the Notes (other than a default referred to in clauses (1) or (2) or (3) above);

(5)default under any mortgage, indenture or instrument under which there is issued or by which there is secured or evidenced any Indebtedness for money borrowed by the Company, the Issuer or any Restricted Subsidiary (or the payment of which is Guaranteed by the Company, the Issuer or any Restricted Subsidiary), whether such Indebtedness or Guarantee now exists, or is created after the Issue Date, which default:

(A)is caused by a failure to pay principal on such Indebtedness at its Stated Maturity (after giving effect to any applicable grace period provided in such Indebtedness) (“payment default”); or

(B)results in the acceleration of such Indebtedness prior to its maturity (the “cross acceleration provision”);

A-13

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 and remains unpaid, aggregates $250 million or more (or its foreign currency equivalent) (it being understood, for the avoidance of doubt, that Indebtedness owed to the Company, the Issuer or any Restricted Subsidiary shall not constitute Indebtedness for the purposes of this clause (5));

(6)failure by the Company, the Issuer or any Significant Subsidiary or any group of Restricted Subsidiaries that, taken together (as of the date of the latest consolidated financial statements of the Company made available to the Holders), would constitute a Significant Subsidiary to pay final judgments aggregating in excess of $250 million (or its foreign currency equivalent) (net of any amounts covered by a reputable and creditworthy insurance company), which judgments are not paid, discharged or stayed for a period of 90 days or more after such judgment becomes final and non-appealable (the “judgment default provision”);

(7)(A) the Company, the Issuer or a Significant Subsidiary or any group of Restricted Subsidiaries that, taken together (as of the date of the latest consolidated financial statements of the Company made available to the Holders), would constitute a Significant Subsidiary, pursuant to or within the meaning of any Bankruptcy Law:

(i)commences a voluntary case;

(ii)consents to the entry of an order for relief against it in an involuntary case or the filing by it of a petition or answer or consent seeking an arrangement of debt, reorganization, dissolution, winding up or relief under applicable Bankruptcy Law;

(iii)consents to the appointment of a Bankruptcy Custodian of it or for any substantial part of its property;

(iv)makes a general assignment for the benefit of its creditors; or

(v)takes any comparable action under any foreign laws relating to insolvency; or

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

(i)is for relief against the Company, the Issuer or a Significant Subsidiary or any group of Restricted Subsidiaries that, taken together (as of the date of the latest consolidated financial statements of the Company made available to the Holders), would constitute a Significant Subsidiary, in an involuntary case;

A-14

(ii)appoints a Bankruptcy Custodian of the Company, the Issuer or a Significant Subsidiary or any group of Restricted Subsidiaries that, taken together (as of the date of the latest consolidated financial statements of the Company made available to the Holders), would constitute a Significant Subsidiary, or for any substantial part of the property of any of the foregoing; or

(iii)orders the winding up or liquidation of the Company, the Issuer or a Significant Subsidiary or any group of Restricted Subsidiaries that, taken together (as of the date of the latest consolidated financial statements of the Company made available to the Holders), would constitute a Significant Subsidiary; or any similar relief is granted under any foreign laws and the order or decree remains unstayed and in effect for 90 days (the provisions of this clause (7) being the “bankruptcy provisions”); or

(8)the Note Guarantee of the Company, or any Note Guarantee of a Significant Subsidiary or any group of Subsidiary Guarantors that, taken together (as of the date of the latest consolidated financial statements of the Company made available to the Holders), would constitute a Significant Subsidiary, ceases to be in full force and effect (except as contemplated by the terms of the Indenture) or is declared null and void in a final and non-appealable judicial proceeding or a responsible officer of the Company or any Subsidiary Guarantor that is a Significant Subsidiary or the responsible officers of any group of Subsidiary Guarantors that, taken together (as of the date of the latest consolidated financial statements of the Company made available to the Holders), would constitute a Significant Subsidiary, denies or disaffirms in writing its obligations under the Indenture or its Note Guarantee, other than by reason of the termination of the Indenture or release of any such Note Guarantee in accordance with the Indenture.

However, a default under clause (4) or (6) will not constitute an Event of Default until the Trustee or the holders of 30% in principal amount of the Notes then outstanding notify the Company and the Issuer of the default and the Company and the Issuer do not cure such default within the time specified after receipt of such notice.

If an Event of Default occurs and is continuing, the Trustee or the holders of at least 30% in principal amount of the Notes then outstanding (by written notice to the Company and the Trustee) may declare the principal of and accrued but unpaid interest on all the Notes to be due and payable. Upon such a declaration, such principal and interest shall be due and payable immediately. If an Event of Default specified under clause (7) occurs and is continuing, the principal of and interest on all the Notes will ipso facto become and be immediately due and payable without any declaration or other act on the part of the Trustee or any Holders. Under

A-15

certain circumstances, the Holders of a majority in principal amount of the Notes then outstanding may rescind any such acceleration with respect to the Notes and its consequences.

Holders may not enforce the Indenture or the Notes except as provided in the Indenture. The Trustee may refuse to enforce the Indenture or the Notes unless it receives indemnity or security reasonably satisfactory to it. Subject to certain limitations, Holders of a majority in principal amount of the Notes may direct the Trustee in its exercise of any trust or power. The Trustee may withhold from Holders notice of any continuing Default (except a Default in payment of principal or interest) so long as a committee of its Trust Officers in good faith determines that withholding notice is not opposed to the interest of the Holders.

15.Trustee Dealings with the Issuer

The Trustee under the Indenture, in its individual or any other capacity, may become the owner or pledgee of Notes and may otherwise deal with the Issuer or its Affiliates with the same rights it would have if it were not Trustee, subject to certain restrictions specified in the Indenture.

16.No Recourse Against Others

A past, present or future director, officer, employee, incorporator, member, partner or stockholder, as such, of the Issuer or any Guarantor, or of any stockholder of the Issuer or any Guarantor, shall not have any liability for any obligations of the Issuer or any Guarantor, either directly or through the Issuer or any Guarantor, as the case may be, under the Notes, Note Guarantees, or the Indenture or for any claim based on, in respect of or by reason of such obligations or their creation whether by virtue of any rule of law, statute or constitutional provision or by the enforcement of any assessment or by any legal or equitable proceeding or otherwise. By accepting a Note, each Holder shall waive and release any and all such liability. The waiver and release shall be part of the consideration for the issue of the Notes.

17.Authentication

This Note shall not be valid until an authorized signatory of the Trustee (or an authenticating agent) manually or electronically signs the certificate of authentication on the other side of this Note.

18.Abbreviations

Exhibit 99.1

FOR IMMEDIATE RELEASE

Alcoa Corporation Announces Closing of Debt Offering to Finance Cash Consideration for Acquisition of South32’s Bauxite, Alumina and Aluminum Assets

September 23, 2026—Pittsburgh— Alcoa Corporation (NYSE:AA, ASX:AAI) (“Alcoa”) announced today the closing of the offering of $2,600,000,000 aggregate principal amount of senior notes (the “notes”), consisting of $1,500,000,000 aggregate principal amount of 6.625% senior notes due 2034 issued by Alumina Pty Ltd (ABN 85 004 820 419) (“Alumina”) and $1,100,000,000 aggregate principal amount of 6.875% senior notes due 2036 issued by Alcoa Nederland Holding B.V. (together with Alumina, the “Issuers”). Each of the Issuers is a wholly-owned subsidiary of Alcoa. The notes are guaranteed on a senior unsecured basis by Alcoa and certain of its subsidiaries.

The Issuers intend to use the net proceeds of the issuance of the notes, together with cash on hand, to fund the approximately $3.1 billion cash portion of the consideration for the previously announced proposed acquisition (the “Acquisition”) by Alcoa of South32 Limited’s (ASX: S32, LSE: S32.L, JSE: S32) (“South32”) interests in certain bauxite, alumina and aluminum smelter operations and to pay related fees and expenses.

Concurrently with the closing of the notes offering, Alcoa terminated all remaining outstanding commitments in respect of the senior unsecured 364-day bridge term loan credit facility entered into in connection with the Acquisition. Completion of the Acquisition is subject to the satisfaction or waiver (if applicable) of certain conditions, including approval of South32’s shareholders, receipt of required regulatory approvals and other customary closing conditions.

The notes and related guarantees were sold in a private placement to persons reasonably believed to be qualified institutional buyers in accordance with Rule 144A under the Securities Act of 1933, as amended (the “Securities Act”), and to certain non-United States persons in offshore transactions in accordance with Regulation S under the Securities Act. The notes and related guarantees have not been and will not be registered under the Securities Act or the securities laws of any other jurisdiction and may not be offered or sold in the United States or to, or for the benefit of, U.S. persons absent registration under, or an applicable exemption from, the registration requirements of the Securities Act.

This press release does not constitute an offer to buy or sell or a solicitation of an offer to buy or sell the notes and related guarantees or any other security or a solicitation of any vote of approval and there will be no offer, solicitation, purchase or sale in any state or jurisdiction in which, or to any persons to whom, such an offer, solicitation, purchase or sale would be unlawful. Any offers of the notes and related guarantees were made only by means of a private offering memorandum.

Cautionary Note Regarding Forward-Looking Statements

This press release contains statements that relate to future events and expectations and as such constitute forward-looking statements within the meaning of the Private Securities Litigation Reform Act of 1995. Forward-looking statements include those containing such words as “aims,” “ambition,” “anticipates,” “believes,” “could,” “develop,” “endeavors,” “estimates,” “expects,” “forecasts,” “goal,” “intends,” “may,” “outlook,” “potential,” “plans,” “projects,” “reach,” “seeks,” “sees,” “should,” “strive,” “targets,” “will,” “working,” “would,” or other words of similar meaning. All statements by Alcoa that reflect expectations, assumptions or projections about the future, other than statements of historical fact, are forward-looking statements, including, without limitation, statements regarding the Acquisition; the ability of the parties to complete the Acquisition on the expected timeline or at all considering the closing conditions; the expected benefits of the Acquisition, including the anticipated synergies and earnings per share and free cash flow accretion; the competitive ability and position following completion of the Acquisition; statements about the intended use of the net proceeds from the issuance of the notes; forecasts concerning global demand growth for bauxite, alumina, and aluminum, and supply/demand balances; statements, projections or forecasts of future or targeted financial results, or operating performance (including our ability to execute on strategies related to environmental, social and governance matters); statements about strategies, outlook, and business and financial prospects (including related to production and shipments); and statements about capital allocation and return of capital. These statements reflect beliefs and assumptions that are based on Alcoa’s perception of historical trends, current conditions, and expected future developments, as well as other factors that management believes are appropriate in the circumstances. Forward-looking statements are not guarantees of future performance and are subject to known and unknown risks, uncertainties, and changes in circumstances that are difficult to predict. Although Alcoa believes that the expectations reflected in any forward-looking statements are based on reasonable assumptions, it can give no assurance that these expectations will be attained and it is possible that actual results may differ materially from those indicated by these forward-looking statements due to a variety of risks and uncertainties. Such risks and uncertainties include, but are not limited to: (a) the non-satisfaction or non-waiver, on a timely basis or otherwise, of one or more closing conditions to the Acquisition; (b) the prohibition or delay of the completion of the Acquisition by a governmental entity; (c) the risk that the Acquisition may not be completed in the expected time frame or at all; (d) unexpected costs, charges or expenses, including financing commitment fees, resulting from the Acquisition; (e) uncertainty of the expected financial performance following completion of the Acquisition; (f) the risk that the parties to the Umbrella Implementation Deed, dated as of June 30, 2026 (the “Deed”), may agree to modify or waive the terms or conditions of the Deed without the consent of the holders of the notes; (g) uncertainty of any contingent payment required to be made in connection with the Acquisition following completion; (h) failure to realize the anticipated benefits of the Acquisition; (i) the occurrence of any event that could give rise to termination of the Acquisition; (j) potential litigation in connection with the Acquisition or other settlements or investigations that may affect the timing or occurrence of the contemplated transaction or result in significant costs of defense, indemnification and liability; (k) the impact of global economic conditions on the aluminum industry and aluminum end-use markets; (l) volatility and declines in aluminum and alumina demand and pricing, including global, regional, and product-specific prices, or significant changes in production costs which are linked to the London Metal Exchange (“LME”) or other commodities; (m) the disruption of market-driven balancing of global

2

aluminum supply and demand by non-market forces; (n) competitive and complex conditions in global markets; (o) our ability to obtain, maintain, or renew permits or approvals necessary for our mining operations; (p) rising energy costs and interruptions or uncertainty in energy supplies; (q) unfavorable changes in the cost, quality, or availability of raw materials or other key inputs, or by disruptions in the supply chain; (r) economic, political, and social conditions, including the impact of trade policies, tariffs, and adverse industry publicity; (s) legal proceedings, investigations, or changes in foreign and/or U.S. federal, state, or local laws, regulations, or policies; (t) changes in tax laws or exposure to additional tax liabilities; (u) climate change, climate change legislation or regulations, and efforts to reduce emissions and build operational resilience to extreme weather conditions; (v) disruptions in the global economy caused by ongoing regional conflicts and wars; (w) fluctuations in foreign currency exchange rates and interest rates, inflation and other economic factors in the countries in which we operate; (x) global competition within and beyond the aluminum industry; (y) our ability to achieve our strategies or expectations relating to environmental, social, and governance considerations; (z) claims, costs, and liabilities related to health, safety and environmental laws, regulations, and other requirements in the jurisdictions in which we operate; (aa) liabilities resulting from impoundment structures, which could impact the environment or cause exposure to hazardous substances or other damage; (bb) dilution of the ownership position of the Alcoa’s stockholders (including as a result of the Acquisition), price volatility, and other impacts on the price of Alcoa common stock by the secondary listing of the Alcoa common stock on the Australian Securities Exchange; (cc) our ability to obtain or maintain adequate insurance coverage; (dd) our ability to execute on our strategy to reduce complexity and optimize our asset portfolio and to realize the anticipated benefits from announced plans, programs, initiatives relating to our portfolio, capital investments, and developing technologies; (ee) our ability to integrate and achieve intended results from joint ventures, other strategic alliances, and strategic business transactions; (ff) significant declines in the market value of our marketable securities; (gg) our ability to fund capital expenditures; (hh) deterioration in our credit profile or increases in interest rates; (ii) impacts on our current and future operations due to our indebtedness and our ability to reduce indebtedness; (jj) our ability to continue to return capital to our stockholders through the payment of cash dividends and/or the repurchase of our common stock; (kk) cyber attacks, security breaches, system failures, software or application vulnerabilities, or other cyber incidents; (ll) labor market conditions, union disputes and other employee relations issues; and (mm) the other risk factors discussed in Alcoa’s Annual Report on Form 10-K for the fiscal year ended December 31, 2025 and other reports filed by Alcoa with the Securities and Exchange Commission (“SEC”). Alcoa cautions readers not to place undue reliance upon any such forward-looking statements, which speak only as of the date they are made. These risks, as well as other risks associated with the Acquisition, are also more fully discussed in the Registration Statement on Form S-4 referred to below. Alcoa disclaims any obligation to update publicly any forward-looking statements, whether in response to new information, future events or otherwise, except as required by applicable law. Neither Alcoa nor any other person assumes responsibility for the accuracy and completeness of any of these forward-looking statements.
