If any Record Date is set pursuant to this paragraph, the Holders of Outstanding Notes on such Record Date, and no other Holders, shall be entitled to take the relevant action, whether or not such Holders remain Holders after such Record Date; provided that no such action shall be effective hereunder unless taken on or prior to the applicable Expiration Date by Holders of the requisite principal amount of Outstanding Notes on such Record Date.

Nothing in this paragraph shall be construed to prevent the Trustee from (i) giving or making any notice required to be made pursuant to the Trustee’s duties and obligations under this Indenture and (ii) setting a new Record Date for any action for which a Record Date has previously been set pursuant to this paragraph (whereupon the Record Date previously set shall automatically and with no action by any Person be cancelled and of no effect), and nothing in this paragraph shall be construed to render ineffective any action taken by Holders of the requisite principal amount of Outstanding Notes on the date such action is taken. Promptly after any Record Date is set pursuant to this paragraph, the Trustee, at the Issuer’s expense, shall cause notice of such Record Date, the proposed action by Holders and the applicable Expiration Date to be given to the Issuer in writing and to each Holder of Notes in the manner set forth in Section 1.6.

16

Nothing in this paragraph shall be construed to prevent the Issuer from setting a new Record Date for any action for which a Record Date has previously been set pursuant to this paragraph (whereupon the Record Date previously set shall automatically and with no action by any Person be cancelled and of no effect), and nothing in this paragraph shall be construed to render ineffective any action taken by Holders of the requisite principal amount of Outstanding Notes on the date such action is taken. Promptly after any Record Date is set pursuant to this paragraph, the Issuer, at its own expense, shall cause notice of such Record Date, the proposed action by Holders and the applicable Expiration Date to be given to the Trustee in writing and to each Holder of Notes in the manner set forth in Section 1.6.

With respect to any Record Date set pursuant to this Section, the party hereto which sets such Record Dates 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 1.6, on or prior to the existing Expiration Date. If an Expiration Date is not designated with respect to any Record Date set pursuant to this Section, the party hereto which set such Record Date shall be deemed to have initially designated the 180th 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 paragraph. Notwithstanding the foregoing, no Expiration Date shall be later than the 180th day after the applicable Record Date.

Without limiting the foregoing, a Holder entitled hereunder 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.

In any case where notice to Holders is given by mail, neither the failure to mail such notice, nor any defect in any notice so mailed, to any particular Holder shall affect the sufficiency of such notice with respect to other Holders. 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.

In case by reason of the suspension of regular mail service or by reason of any other cause it shall be impracticable to give such notice by mail, then such notification as shall be made with the approval of the Trustee shall constitute a sufficient notification for every purpose hereunder.

Each of the Issuer and the Guarantors further agrees to take any and all action, including the execution and filing of any and all such documents and instruments as may be necessary to continue such designation and appointment of Cogency Global Inc. in full force and effect so long as this Indenture shall be in full force and effect; provided that the Issuer and the Guarantors may and shall (to the extent Cogency Global Inc. ceases to be able to be served on the basis contemplated herein), by written notice to the Trustee, designate such additional or alternative agents for service of process under this Section 1.13 that (i) maintains an office located in the Borough of Manhattan, The City of New York in the State of New York, (ii) are either (x) counsel for the Issuer and the Guarantors or (y) a corporate service company which acts as agent for service of process for other persons in the ordinary course of its business and (iii) agrees to act as agent for service of process in accordance with this Section 1.13. Such notice shall identify the name of such agent for process and the address of such agent for process in the Borough of Manhattan, The City of New York, State of New York. Upon the request of any Holder, the Trustee shall deliver such information to such Holder. Notwithstanding the foregoing, there shall, at all times, be at least one agent for service of process for the Issuer and the Guarantors appointed and acting in accordance with this Section 1.13.

(c) To the extent that the Issuer or the Guarantors has or hereafter may acquire any immunity from jurisdiction of any court or from any legal process (whether through service of notice, attachment prior to judgment, attachment in aid of execution, execution or otherwise) with respect to itself or its property, each of the Issuer and the Guarantors hereby irrevocably waives such immunity in respect of its obligations under this Indenture, the Notes and the Guarantees, to the fullest extent permitted by law.

Section 1.14. Currency of Account; Conversion of Currency; Foreign Exchange Restrictions.

(a) U.S. Dollars are the sole currency of account and payment for all sums payable by the Issuer and the Guarantors under or in connection with the Notes, the Guarantees or this Indenture, including damages. Any amount received or recovered in a currency other than U.S. dollars (whether as a result of, or of the enforcement of, a judgment or order of a court of any jurisdiction, in the winding-up or dissolution of the Issuer or the Guarantors or otherwise) by any Holder of the Notes in respect of any sum expressed to be due to it from the Issuer or the Guarantors shall only constitute a discharge to the Issuer or the Guarantors, as the case may be, to the extent of the U.S. dollar amount which the recipient is able to purchase with the amount so received or recovered in that other currency on the date of that receipt or recovery (or, if it is not practicable to make that purchase on that date, on the first date on which it is practicable to do so). If that U.S. dollar amount is less than the U.S. dollar amount expressed to be due to the recipient under the Notes, the Issuer and the Guarantors shall, jointly and severally, indemnify it

21

against any loss sustained by it as a result as set forth in Section 1.14(b). In any event, the Issuer and the Guarantors shall, jointly and severally, indemnify the recipient against the cost of making any such purchase. For the purposes of this Section 1.14, it will be sufficient for the Holder of a Note to certify in a satisfactory manner (indicating sources of information used) that it would have suffered a loss had an actual purchase of U.S. dollars been made with the amount so received in that other currency on the date of receipt or recovery (or, if a purchase of U.S. dollars on such date had not been practicable, on the first date on which it would have been practicable, it being required that the need for a change of date be certified in the manner mentioned above). The indemnities set forth in this Section 1.14 constitute separate and independent obligations from other obligations of the Issuer and the Guarantors, shall give rise to a separate and independent cause of action, shall apply irrespective of any indulgence granted by any Holder of the Notes and shall continue in full force and effect despite any other judgment, order, claim or proof for a liquidated amount in respect of any sum due under the Notes.

(b) The Issuer and the Guarantors covenant and agree that the following provisions shall apply to conversion of currency in the case of the Notes, the Guarantees and this Indenture:

(i) (A) if for the purpose of obtaining judgment in, or enforcing the judgment of, any court in any country, it becomes necessary to convert into a currency (the “judgment currency”) an amount due in any other currency (the “Base Currency”), then the conversion shall be made at the rate of exchange prevailing on the Business Day before the day on which the judgment is given or the order of enforcement is made, as the case may be (unless a court shall otherwise determine), and

(B) if there is change in the rate of exchange prevailing between the Business Day before the day on which the judgment is given or an order of enforcement is made, as the case may be (or such other date as a court shall determine), and the date of receipt of the amount due, the Issuer or the Guarantors, as the case may be, will pay such additional (or, as the case may be, such lesser) amount, if any, as may be necessary so that the amount paid in the judgment currency when converted at the rate of exchange prevailing on the date of receipt will produce the amount in the Base Currency originally due;

(ii) in the event of the winding-up of the Issuer or the Guarantors at any time while any amount or damages owing under the Notes, the Guarantees and this Indenture, or any judgment or order rendered in respect thereof, shall remain outstanding, the Issuer and the Guarantors shall, jointly and severally, indemnify and hold the Holders and the Trustee harmless against any deficiency arising or resulting from any variation in rates of exchange between (1) the date as of which the U.S. Dollar Equivalent of the amount due or contingently due under the Notes, the Guarantees and this Indenture (other than under this Subsection (b)(ii)) is calculated for the purposes of such winding-up and (2) the final date for the filing of proofs of claim in such winding-up. For the purpose of this subsection (b)(ii), the final date for the filing of proofs of claim in the winding-up of the Issuer or the Guarantors, as the case may be, shall be the date fixed by the liquidator or otherwise in accordance with the relevant provisions of applicable law as being the latest practicable date as at which liabilities of the Issuer or the Guarantors, as the case may be, may be ascertained for such winding-up prior to payment by the liquidator or otherwise in respect thereto;

22

(iii) the obligations contained in Subsections (a), (b)(i)(B) and (b)(ii) of this Section 1.14 shall constitute separate and independent obligations from the other obligations of the Issuer and the Guarantors under the terms of this Indenture, shall give rise to separate and independent causes of action against the Issuer and the Guarantors, shall apply irrespective of any waiver or extension granted by any Holder or the Trustee or either of them from time to time and shall continue in full force and effect notwithstanding any judgment or order or the filing of any proof of claim in the winding-up of the Issuer or the Guarantors for a liquidated sum in respect of amounts due hereunder (other than under Subsection (b)(ii) above) or under any such judgment or order. Any such deficiency as aforesaid shall be deemed to constitute a loss suffered by the Holders or the Trustee, as the case may be, and no proof or evidence of any actual loss shall be required by the Issuer or the Guarantors or the liquidator or otherwise or any of them. In the case of subsection (b)(ii) above, the amount of such deficiency shall not be deemed to be reduced by any variation in rates of exchange occurring between the said final date and the date of any liquidating distribution; and

(iv) the term “rate(s) of exchange” shall mean the rate of exchange quoted by Reuters at 10:00 a.m. (New York time) for spot purchases of the Base Currency with the judgment currency other than the Base Currency referred to in Subsections (b)(i) and (b)(ii) above and includes any premiums and costs of exchange payable.

(c) In the event that on any Interest Payment Date, the Maturity Date or Redemption Date, as the case may be, in respect of the Guarantee provided by a Guarantor, any restrictions or prohibition of access to the foreign exchange market of the jurisdiction of incorporation of a Guarantor exists, such Guarantor agrees to pay all amounts payable under the Notes and such Guarantee in the currency of the Notes by means of any legal procedure existing in such jurisdiction of incorporation (except commencing legal proceedings against the relevant Central Bank), on any due date for payment under the Notes, for the purchase of the currency of such Notes. All costs and taxes payable in connection with the procedures referred to in this Section 1.14 shall be borne by the relevant Guarantor.

(d) Notwithstanding anything to the contrary contained herein, neither the Trustee nor the Principal Paying Agent shall have any liability for converting into U.S. Dollars any amount received by any Holder in a currency other than U.S. Dollars.

Section 1.15. Counterparts.

This Indenture may be executed in two or more counterparts, each of which shall be deemed to be an original, but all of which together shall constitute one and the same instrument.

The use of electronic signatures and electronic records (including, without limitation, any contract or other record created, generated, sent, communicated, received, or stored by electronic methods) shall be of the same legal effect, validity and enforceability as a manually executed signature or use of a paper-based recordkeeping system to the fullest extent permitted by applicable law, including, without limitation, the Federal Electronic Signatures in Global and National Commerce Act, the New York State Electronic Signatures and Records Act and any other applicable law, including, without limitation, any state law based on the Uniform Electronic Transactions Act or the Uniform Commercial Code.

Section 1.16. Force Majeure.

In no event shall the Trustee or any Agent 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, pandemics, epidemics, 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 or such Agent shall use reasonable efforts which are consistent with accepted practices in the banking industry to resume performance as soon as practicable under the circumstances.

In order to comply with the laws, rules, regulations and executive orders in effect from time to time applicable to banking institutions, including, without limitation, those relating to the funding of terrorist activities and money laundering, including Section 326 of the USA PATRIOT Act of the United States (“Applicable Law”), the Trustee and Agents are required to obtain, verify, record and update certain information relating to individuals and entities which maintain a business relationship with the Trustee and Agents. Accordingly, each of the parties agrees to provide to the Trustee and Agents, upon their request from time to time such identifying information and documentation as may be available for such party in order to enable the Trustee and Agents to comply with Applicable Law.

Section 1.18. Anti-Money Laundering, Terrorism and Economic Sanctions.

(a) The Trustee or any Agent may take and instruct any delegate to take any action which it in its sole discretion considers appropriate so as to comply with any applicable law, regulation, request of a public or regulatory authority or any internal group policy (including any “Know Your Client” and/or other compliance policy) which relates to the prevention of fraud, money laundering, terrorism or other criminal activities or the provision of financial and other services to sanctioned persons or entities. Such action may include but is not limited to the interception and investigation of transactions on the Issuer’s or any Guarantor’s accounts (particularly those involving the international transfer of funds) including the source of the intended recipient of funds paid into or out of the Issuer’s or any Guarantor’s accounts. None of the Trustee, any Agent or any delegate will be liable for any loss (whether direct or consequential and including, without limitation, loss of profit or interest) caused in whole or in part by any actions which are taken by the Trustee, any Agent or any delegate pursuant to this Section 1.18.

24

(b) The Issuer and each Guarantor covenants and represents, jointly and severally, that neither it nor any of their respective subsidiaries or their respective directors or officers, and, to the knowledge of the Issuer or any Guarantor, any of their affiliates are the target or subject of any sanctions enforced by the US Government, (including, without limitation, the Office of Foreign Assets Control of the US Department of the Treasury or the US Department of State), the United Nations Security Council, the European Union, His Majesty’s Treasury, or other relevant sanctions authority (collectively “Sanctions”);

The Issuer and each Guarantor agrees that (a) if reasonably requested by the Trustee or any of the Agents and required by FATCA, in relation to a payment made under this Indenture and the Notes issued hereunder, the Issuer or the Guarantors will provide such information if and to the extent that (i) such information is reasonably necessary for each of the Trustee and the Agents to determine that it is in compliance with FATCA as relates to the payments made under this Indenture and the Notes issued hereunder and (ii) such information is reasonably available to the Issuer or the Guarantors, as applicable with regard to the Issuer or Guarantors in relation to the requirements of FATCA that are actually imposed upon such requesting Trustee or Agent, as applicable; provided, however, that neither the Issuer nor any Guarantor shall be required to provide information that it is prohibited legally from disclosing and (b) the Trustee and each applicable Agent shall be entitled to make any withholding or deduction from payments to the extent necessary to comply with FATCA, for which the Trustee and the Agents shall have no liability.

Section 2.3. Form of Reverse of Note.

This Note is one of a duly authorized issue of Notes of the Issuer designated as its 6.750% Senior Unsecured Notes due 2034 (the “Notes”) issued under an Indenture, dated as of April 9, 2024 (herein called the “Indenture”), among the Issuer, the Guarantors named therein, and The Bank of New York Mellon, a New York banking corporation, as trustee (the “Trustee”), as principal paying agent (the “Principal Paying Agent” and any other paying agents to be appointed hereunder, the “Paying Agents”), as transfer agent (the “Transfer Agent”) and registrar (the “Registrar”). Reference is hereby made to the Indenture and all indentures supplemental thereto for a statement of the respective rights, limitations of rights, duties and immunities thereunder of the Issuer, the Guarantors, the Trustee, the Transfer Agent and the Notes are, and are to be, authenticated and delivered. Terms used but not defined in this Note are defined in the Indenture.

As provided in the Indenture and subject to certain limitations therein set forth, the obligations of the Issuer under the Indenture and this Note are guaranteed pursuant to the Guarantees set forth in the Indenture. Each Holder, by holding this Note, agrees to all of the terms and provisions of said Guarantees. Reference is hereby made to the Indenture for a statement of the respective rights, limitations of rights, duties and obligations thereunder of the Guarantors, the Trustee and the Holders.

The Issuer may from time to time, without the consent of the Holders of the Notes, create and issue Additional Notes having the same terms and conditions as the Initial Notes in all respects, except that the issue date, the issue price and the first payment of interest thereon may differ; provided, however, that unless the Additional Notes are treated as part of the same “issue” of debt instruments as the Initial Notes or are issued pursuant to a “qualified reopening” of the Initial Notes, or are issued with less than a de minimis amount of original issue discount, in each case for U.S. federal income tax purposes, the Additional Notes will have a separate CUSIP or ISIN number (as applicable). Additional Notes shall be consolidated with and shall form a single series and vote together with the previously issued Notes for all purposes under the Indenture.

If as a result of any Change of Law (as defined in the Indenture): (i) the Issuer or a Guarantor is or would be required on the next succeeding Interest Payment Date to pay any Additional Amounts referred to in Section 11.9 of the Indenture in excess of the Additional Amounts that the Issuer or such Guarantor, as the case may be, would pay if payments in respect of the Notes were subject to deduction or withholding for Taxes imposed by the applicable taxing jurisdiction at the rate applicable on the Issue Date; or (ii) the issuers/borrowers of certain intercompany debt are or would be required on the next succeeding interest payment date to pay Brazilian withholding taxes in excess of a general rate of 15%, or 25% in case of amounts paid to residents of countries or locations which do not impose any income tax or which impose it at a maximum rate lower than 17% or where the laws of that country or location impose restrictions on the disclosure (x) of shareholding composition; (y) of the ownership of the investment; or (z) to the identification of the beneficial owner of income attributed to non-resident persons, pursuant to article 8 of Law No. 9,779, of January 19, 1999, and articles 24 and 24-A of Law No. 9,430, of December 27, 1996; provided that, such requirement to pay such taxes in excess of such rate was not caused by, or otherwise the result of, whether directly or indirectly, wholly or in part, any amendment to the intercompany debt, and in either case, the payment of such excess

30

amounts cannot be avoided by the use of any reasonable measures available to the Issuer or a Guarantor, the Notes may be redeemed, by the Issuer at the option of the Issuer or a Guarantor, in whole but not in part, upon not less than 30 nor more than 90 days’ notice to the Holders, which notice will be published, at any time following such Change of Law at a Redemption Price equal to the principal amount thereof, plus accrued and unpaid interest, if any, to the date fixed for redemption. The Issuer, any Guarantor or any of their respective Affiliates will also pay to Holders of the Notes on the Redemption Date any Additional Amounts which are payable.

Following such redemption, the Notes will be cancelled, or remain Outstanding, at the Issuer’s or a Guarantor’s election. Prior to the delivery of any notice of redemption in accordance with the foregoing, the Issuer or a Guarantor shall deliver to the Trustee and the Agents an Officer’s Certificate stating that the Issuer or a Guarantor, as the case may be, is entitled to effect such redemption based on an Opinion of Counsel or written advice of a qualified tax expert, that the Issuer or a Guarantor has or will become obligated to pay such excess amounts with respect to Taxes as a result of such Change of Law. Such notice, once delivered by the Issuer or a Guarantor to the Trustee, will be irrevocable.

At any time before January 9, 2034 (which is the date that is three months prior to maturity of the notes (the “Par Call Date”)), the Issuer or a Guarantor has the right to redeem the Notes, in whole or in part and from time to time, at a Redemption Price equal to the greater of (1) 100% of the principal amount of the Notes being redeemed and (2) the sum of the present values of the remaining scheduled payments of principal and interest on the Notes being redeemed that would be due if the Notes matured on the Par Call Date (inclusive of interest accrued to the redemption date), discounted to the Redemption Date on a semi-annual basis (assuming a 360-day year consisting of twelve 30-day months) at the Treasury Rate plus 40 basis points, less interest accrued to, but excluding, the Redemption Date; plus, in either case, accrued and unpaid interest on the principal amount of the Notes being redeemed and Additional Amounts, if any, to, but excluding, 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).

At any time on or after the Par Call Date, the Issuer or a Guarantor has the right to redeem the Notes, in whole or in part and from time to time, at a Redemption Price equal to 100% of the principal amount of the Notes being redeemed plus accrued and unpaid interest on the principal amount of the Notes being redeemed to, but excluding, such 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).

The “Treasury Rate” shall be determined by the Issuer or a Guarantor after 4:15 p.m., New York City time (or after such time as yields on U.S. government securities are posted daily by the Board of Governors of the Federal Reserve System), on the third Business Day preceding the Redemption Date based upon the yield or yields for the most recent day that appear after such time on such day in the most recent statistical release published by the Board of Governors of the Federal Reserve System designated as “Selected Interest Rates (Daily) - H.15” (or any successor designation or publication) (“H.15”) under the caption “U.S. government securities–Treasury constant maturities–Nominal” (or any successor caption or heading). In determining the Treasury Rate, the Issuer or a Guarantor shall select, as applicable: (i) the yield for the Treasury constant maturity on H.15 exactly equal to the period from the redemption date to the Par Call

Date (the “Remaining Life”); or (ii) if there is no such Treasury constant maturity on H.15 exactly equal to the Remaining Life, the two yields – one yield corresponding to the Treasury constant maturity on H.15 immediately shorter than and one yield corresponding to the Treasury constant maturity on H.15 immediately longer than the Remaining Life – and shall interpolate to the Par Call Date on a straight-line basis (using the actual number of days) using such yields and rounding the result to three decimal places; or (iii) if there is no such Treasury constant maturity on H.15 shorter than or longer than the Remaining Life, the yield for the single Treasury constant maturity on H.15 closest to the Remaining Life. For purposes of this paragraph, the applicable Treasury constant maturity or maturities on H.15 shall be deemed to have a maturity date equal to the relevant number of months or years, as applicable, of such Treasury constant maturity from the Redemption Date.

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

The Issuer or a Guarantor’s actions and determinations in determining the Redemption Price shall be conclusive and binding for all purposes, absent manifest error.

The Issuer, any Guarantor or any of their respective Affiliates may at any time repurchase the Notes at any price in the open market or otherwise. The Issuer, any Guarantor or any of their respective Affiliates may hold or resell the Notes it purchases or may surrender them to the Trustee or an Agent for cancellation.

Optional Clean-up Redemption. Notwithstanding the foregoing, in connection with any tender offer for the notes (including an Offer to Purchase in connection with a Change of Control that results in a Rating Decline made in accordance with the terms of the Indenture), in the event that the Holders of not less than 85% of the aggregate principal amount of the outstanding Notes validly tender and do not validly withdraw Notes in such tender offer and the Issuer, or any other Person making such offer in lieu of the Issuer, purchases all of the Notes validly tendered and not

32

validly withdrawn by such Holders, then the Issuer or the Guarantor will have the right, on not less than 10 nor more than 60 days’ prior notice to the Holders (with a copy to the Trustee), to redeem all of the Notes that remain outstanding at a Redemption Price equal to the purchase price paid to each other Holder in such tender offer plus, to the extent not included in the purchase price, accrued and unpaid interest and Additional Amounts, if any, on the Notes that remain outstanding, to, but excluding, the Redemption Date.

[Include if Note is a Regulation S Global Note — If the holder of a beneficial interest in this Regulation S Global Note at any time wishes to transfer such interest to a Person who wishes to take delivery thereof in the form of a beneficial interest in the Restricted Global Note, such transfer may be effected, subject to the rules and procedures of the Depositary, Euroclear and Clearstream, in each case to the extent applicable and as in effect from time to time, only in accordance with the terms of this paragraph. Upon receipt by the Trustee, as Registrar, of (A) written instructions given by or on behalf of the Depositary in accordance with the rules and procedures of the Depositary, Euroclear and Clearstream, in each case to the extent applicable and as in effect from time to time directing the Trustee to credit or cause to be credited to a specified Agent Member’s account a beneficial interest in the Restricted Global Note in a specified principal amount and to cause to be debited from another specified Agent Member’s account a beneficial interest in this Regulation S Global Note in an equal principal amount; and (B) a certificate in substantially the form set forth in Exhibit B to the Indenture signed by or on behalf of the Agent Member holding such beneficial interest in this Regulation S Global Note, the Trustee, as Registrar, shall reduce the principal amount of this Regulation S Global Note and increase the principal amount of the Restricted Global Note by such specified principal amount.]

[Include if Note is a Restricted Global Note — If the holder of a beneficial interest in this Restricted Global Note wishes at any time to transfer such interest to a Person who wishes to take delivery thereof in the form of a beneficial interest in the Regulation S Global Note, such transfer may be effected, subject to the rules and procedures of the Depositary, Euroclear and Clearstream, in each case to the extent applicable and as in effect from time to time, only in accordance with the terms of this paragraph. Upon receipt by the Trustee, as Registrar of:

(A) written instructions given by or on behalf of the Depositary in accordance with the rules and procedures of the Depositary, Euroclear and Clearstream, in each case to the extent applicable and as in effect from time to time directing the Trustee to credit or cause to be credited to a specified Agent Member’s account a beneficial interest in the Regulation S Global Note in a specified principal amount and to cause to be debited from another specified Agent Member’s account a beneficial interest in the Restricted Global Note in an equal principal amount; and

(B) a certificate in substantially the form set forth in Exhibit A of the Indenture signed by or on behalf of the Agent Member holding such beneficial interest in this Restricted Global Note,

the Trustee, as Registrar, shall reduce the principal amount of this Restricted Global Note, and increase the principal amount of the Regulation S Global Note by such specified principal amount.]

33

The Notes do not have the benefit of any sinking fund obligations.

In the event of redemption or purchase of this Note in part only, a new Note or Notes of like tenor for the unredeemed or unpurchased portion hereof will be issued in the name of the Holder hereof upon the cancellation hereof.

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

The Indenture contains provisions for defeasance at any time of (i) the entire indebtedness of this Note, or (ii) certain restrictive covenants and Events of Default with respect to this Note, in each case upon compliance with certain conditions set forth therein.

Unless the context otherwise requires, the Notes shall constitute one series for all purposes under the Indenture, including without limitation, amendments, waivers or redemption.

The Indenture permits, with certain exceptions as therein provided, the amendment thereof and the modification of the rights and obligations of the Issuer and the Guarantors and the rights of the Holders of the Notes under the Indenture at any time by the Issuer and the Trustee with the consent of the Holders of a majority in aggregate principal amount of the Notes at the time Outstanding. The Indenture also contains provisions permitting the Holders of specified percentages in aggregate principal amount of the Notes at the time Outstanding, on behalf of the Holders of all the Notes, to waive compliance by the Issuer or the Guarantors with certain provisions of the Indenture and certain past defaults under the Indenture and their consequences.

Any such consent or waiver by the Holder of this Note shall be conclusive and binding upon such Holder and upon all future Holders of this Note and of any Note issued upon the registration of transfer hereof or in exchange herefor or in lieu hereof, whether or not notation of such consent or waiver is made upon this Note.

No reference herein to the Indenture and no provision of this Note or of the Indenture shall alter or impair the obligation of the Issuer, which is absolute and unconditional, to pay the principal of (and premium, if any) and interest on this Note at the times, place and rate, and in the coin or currency, herein prescribed.

As provided in the Indenture and subject to certain limitations therein set forth, the transfer of this Note is registrable in the Note Register, upon surrender of this Note for registration of transfer at the office or agency of the Issuer in the Borough of Manhattan, The City of New York, New York, or of any of the Transfer Agents duly endorsed by, or accompanied by a written instrument of transfer in form satisfactory to the Issuer duly executed by, the Holder hereof or his attorney duly authorized in writing, and thereupon one or more new Notes, of authorized denominations and like tenor and for the same aggregate principal amount, will be issued to the designated transferee or transferees.

The Notes are issuable only in registered form without coupons in minimum denominations of U.S.$200,000 and integral multiples of U.S.$1,000 in excess thereof. As provided in the Indenture and subject to certain limitations therein set forth, Notes are exchangeable for a like tenor and aggregate principal amount of Notes of a different authorized denomination, as requested by the Holder surrendering the same.

34

No service charge shall be made for any such registration of transfer or exchange, but the Issuer or the Trustee may require payment of a sum sufficient to cover any tax or other governmental charge payable in connection therewith, other than for any transfer or exchange pursuant to Section 3.4, 10.5 or 11.5 of the Indenture.

Prior to due presentment of this Note for registration of transfer, the Issuer, the Trustee, the Transfer Agents and any agent of the Issuer or the Trustee may treat the Person in whose name this Note is registered as the owner hereof for all purposes, whether or not this Note be overdue, and none of the Issuer, the Trustee or any such agent shall be affected by notice to the contrary.

Interest on this Note shall be computed on the basis of a 360-day year of twelve 30-day months each and, in the case of an incomplete month, on the number of days elapsed based on a 30-day month.

All terms used in this Note which are defined in the Indenture shall have the meanings assigned to them in the Indenture.

THE INDENTURE, THIS NOTE AND THE GUARANTEES SHALL BE GOVERNED BY, AND CONSTRUED IN ACCORDANCE WITH, THE LAWS OF THE STATE OF NEW YORK, without regard to conflicts of laws principles thereof. For the purposes of paragraph 2 of article 9 of the Brazilian Decree-Law No. 4,567, dated September 4, 1942, as amended, the Trustee shall be deemed the “proponent” of the transactions contemplated by the Indenture. Articles 84 through 94-8 of the Luxembourg law dated August 10, 1915 on commercial companies, as amended, which set the provisions related to the representation of the Holders of the Notes, are not applicable to the Notes or the Guarantees.

The Issuer and the Guarantors agree that any suit, action or proceeding against any of them brought by any Holder or the Trustee arising out of or based upon this Indenture, the Notes or the Guarantees may be instituted in any state or Federal court in The City of New York, New York, and waive any objection which any of them may now or hereafter have to the laying of venue of any such proceeding, and irrevocably submits to the non-exclusive jurisdiction of such courts in any suit, action or proceeding.

The Issuer may change any Paying Agent, the Registrar or Transfer Agent; provided that the Issuer will maintain an office or agency where the Notes may be presented or surrendered for payment and for registration of transfer in the Borough of Manhattan, The City of New York. Upon any such change, the Issuer shall give written notice thereof to the Trustee, the Principal Paying Agent and the Holders.

U.S. dollars are the sole currency of account and payment for all sums payable by the Issuer and the Guarantors under or in connection with the Notes, the Guarantees or the Indenture, including damages. The Issuer and the Guarantors have agreed that the provisions of Section 1.14 of the Indenture shall apply to conversion of currency in the case of the Notes, the Guarantees and the Indenture. Among other things, Section 1.14 specifies that if there is a

35

change in the rate of exchange prevailing between the Business Day before the day on which a judgment is given or an order of enforcement is made, as the case may be (or such other date as a court shall determine), and the date of receipt of the amount due, the Issuer or the relevant Guarantor, as the case may be, will pay such additional (or, as the case may be, such lesser) amount, if any, as may be necessary so that the amount paid in the judgment currency when converted at the rate of exchange prevailing on the date of receipt will produce the amount in the Base Currency originally due.

Each of the Issuer and the Guarantors has appointed Cogency Global Inc., currently located at 122 East 42nd Street, 18th Floor, New York, NY 10168, as its authorized agent upon which process may be served in any suit, or proceeding with respect to, arising out of, or relating to, this Note, the Indenture or the Guarantees, that may be instituted in any Federal or state court in the State of New York, The City of New York, the Borough of Manhattan, or brought under Federal or state securities laws and has agreed that there shall, at all times, be at least one agent for service of process for the Issuer and the Guarantors appointed and acting in accordance with the provisions of Section 1.13 of the Indenture relating to agent for service of process. To the extent that the Issuer or the Guarantors has or hereafter may acquire any immunity from jurisdiction of any court or from any legal process (whether through service of notice, attachment prior to judgment, attachment in aid of execution, execution or otherwise) with respect to itself or its property, each of the Issuer and the Guarantors has irrevocably waived such immunity in respect of its obligations under the Indenture, this Note and the Guarantees, to the fullest extent permitted by law.

Article III

THE NOTES

Section 3.1. Title and Terms.

On the Issue Date, the Trustee shall authenticate and deliver U.S.$600,000,000 aggregate principal amount of 6.750% Senior Unsecured Notes due 2034. The Issuer may from time to time, without the consent of the Holders of the Notes, create and issue Additional Notes having the same terms and conditions as the Initial Notes in all respects, except that the issue date, the issue price and the first payment of interest thereon may differ; provided, however, that unless the Additional Notes are treated as part of the same “issue” of debt instruments as the Initial Notes or are issued pursuant to a “qualified reopening” of the Initial Notes, or are issued with less than a de minimis amount of original issue discount, in each case for U.S. federal income tax purposes, the Additional Notes will have a separate CUSIP or ISIN number (as applicable). Any Additional Notes shall be consolidated with and shall form a single series and vote together with the previously issued Notes for all purposes under this Indenture.

The Notes shall be known and designated as the “6.750% Senior Unsecured Notes due 2034” of the Issuer. The Stated Maturity of the Notes shall be April 9, 2034. The Notes shall bear interest at the rate of 6.750% per annum, from April 9, 2024 or from the most recent Interest Payment Date thereafter to which interest has been paid or duly provided for, as the case may be, payable semiannually in arrears on April 9 and October 9, commencing on October 9, 2024, until the principal thereof is paid or made available for payment.

In the case of a default in payment of principal and premium, if any, upon acceleration or redemption, interest (and Additional Amounts, if any) shall be payable pursuant to the second paragraph of this Section 3.1 on such overdue principal (and premium, if any), such interest shall be payable on demand and, if not so paid on demand, such interest shall itself bear interest at the rate per annum stated in the form of security contained herein plus 1% per annum (to the extent that the payment of such interest shall be legally enforceable), and shall accrue from the date such principal and/or premium, as the case may be, was due and payable to the date payment of such interest (and Additional Amounts, if any) has been made or duly provided for, and such interest on unpaid interest shall also be payable on demand.

The principal of and premium, if any, and interest on the Notes shall be payable at the Corporate Trust Office, the office of the Paying Agents and at any other office or agency maintained by the Issuer for such purpose; provided, however, that at the option of the Issuer upon five (5) Business Days’ notice to the applicable Paying Agent, payment of interest may be made by check mailed to the address of the Person entitled thereto as such address shall appear in the Note Register.

The Notes shall be redeemable or repurchasable as provided in Article XI. The Notes shall not have the benefit of any sinking fund obligations.

The Notes shall be subject to defeasance at the option of the Issuer as provided in Article XII.

38

Unless the context otherwise requires, the Notes shall constitute one series for all purposes under this Indenture, including, without limitation, amendments, waivers or redemptions

Section 3.2. Denominations.

The Notes are issuable only in fully registered form, without coupons, in a minimum denomination of U.S.$200,000 and integral multiples of U.S.$1,000 in excess thereof.

Section 3.3. Execution, Authentication, Delivery and Dating.

The Notes shall be executed on behalf of the Issuer by an authorized signatory or authorized signatories of the Issuer. The signature of any signatory on the Notes may be manual, electronic or facsimile.

Notes bearing the manual, electronic or facsimile signatures of individuals who were at any time the proper officers of the Issuer shall bind the Issuer, notwithstanding that such individuals or any of them have ceased to hold such offices prior to the authentication and delivery of such Notes or did not hold such offices at the date of such Notes.

At any time and from time to time after the execution and delivery of this Indenture, the Issuer may deliver Notes executed by the Issuer and having endorsed (by attachment or imprint) thereon the Guarantees executed as provided in Section 14.2 by the Guarantors, to the Trustee for authentication, together with an Issuer Order for the authentication and delivery of such Notes; and the Trustee in accordance with such Issuer Order shall authenticate and deliver such Notes as in this Indenture provided and not otherwise.

Each Note shall be dated the date of its authentication.

No Note or Guarantee shall be entitled to any benefit under this Indenture or be valid or obligatory for any purpose unless there appears on such Note a certificate of authentication substantially in the form provided for herein executed by the Trustee by manual or electronic signature, and such certificate upon any Note shall be conclusive evidence, and the only evidence, that such Note has been duly authenticated and delivered hereunder and that the Guarantees referred to therein have been duly executed and delivered hereunder.

Section 3.4. Global Notes; Registration, Registration of Transfer and Exchange.

(a) Global Notes. The provisions of clauses (1) through (7) below shall apply only to Global Notes:

(1) each Global Note authenticated under this Indenture shall be registered in the name of the Depositary or a nominee thereof and delivered to the Depositary or a nominee thereof or custodian therefor, and each such Global Note shall constitute a single Note for all purposes of this Indenture;

(2) notwithstanding any other provision in this Indenture, no Global Note may be exchanged in whole or in part for Notes registered, and no transfer of a Global Note in

39

whole or in part may be registered, in the name of any Person other than the Depositary or a nominee thereof unless (A) the Depositary (i) has notified the Issuer that it is unwilling or unable to continue as Depositary for such Global Note and the Issuer thereupon fails to appoint a successor Depositary or (ii) has ceased to be a clearing agency registered under the Exchange Act, (B) the Issuer, at its option, notifies the Trustee in writing that it elects to cause the issuance of the Notes in definitive registered certificated form, or (C) an Event of Default has occurred and is continuing and the Registrar has received a written request from a beneficial owner of the Notes through an Agent Member to issue its proportionate interest in the Global Note in certificated form;

(3) if any Global Note is to be exchanged for other Notes or cancelled in whole, it shall be surrendered by or on behalf of the Depositary or its nominee to the Trustee, as Registrar, for exchange or cancellation as provided in this Article III. If any Global Note is to be exchanged for other Notes or cancelled in part, or if another Note is to be exchanged in whole or in part for a beneficial interest in any Global Note, such Global Note shall be so surrendered for exchange or cancellation as provided in this Article III or, if the Trustee is acting as custodian for the Depositary or its nominee (or is party to a similar arrangement) with respect to such Global Note, the principal amount thereof shall be reduced or increased by an amount equal to the portion thereof to be so exchanged or cancelled, or the principal amount of such other Note to be so exchanged for a beneficial interest therein, as the case may be, in each case by means of an appropriate adjustment made on the records of the Trustee, whereupon the Trustee, in accordance with the Applicable Procedures, shall instruct the Depositary or its authorized representatives to make a corresponding adjustment to its records (including by crediting or debiting any Agent Member’s account as necessary to reflect any transfer or exchange of a beneficial interest pursuant to Section 3.4(c)). Upon any such surrender or adjustment of a Global Note, the Trustee shall, subject to Section 3.4(a)(2) and as otherwise provided in this Article III, authenticate and deliver any Notes issuable in exchange for such Global Note (or any portion thereof) to or upon the order of, and registered in such names as may be directed by, the Depositary or its authorized representative. Upon the request of the Trustee in connection with the occurrence of any of the events specified in the preceding paragraph, the Issuer shall promptly make available to the Trustee a reasonable supply of Notes that are not in the form of Global Notes. The Trustee shall be entitled to conclusively rely upon any order, direction or request of the Depositary or its authorized representative which is given or made pursuant to this Article III if such order, direction or request is given or made in accordance with the Applicable Procedures;

(4) every Note authenticated and delivered upon registration of transfer of, or in exchange for or in lieu of, a Global Note or any portion thereof, whether pursuant to this Article III or Section 10.5 or otherwise, shall be authenticated and delivered in the form of, and shall be, a Global Note, unless such Note is registered in the name of a Person other than the Depositary or a nominee thereof;

(5) none of the Issuer, the Guarantors, the Trustee, any agent of the Trustee, any Paying Agent or the Registrar will have any responsibility or liability for any aspect of the Depositary’s records (or the records of the participant of such Depositary) relating to or payments made on account of beneficial ownership interests of a Global Note or for maintaining, supervising or reviewing any records of the Depositary relating to such beneficial ownership interests;

40

(6) subject to the provisions in the legends required by Section 2.2 above, the registered Holder may grant proxies and otherwise authorize any Person, including Agent Members and Persons who may hold interests in Agent Members, to take any action that such Holder is entitled to take under this Indenture;

(7) except as provided in Section 3.4(a)(2) herein, neither Agent Members nor any other Person on whose behalf Agent Members may act shall have any rights under this Indenture with respect to any Global Note held on their behalf by the Depositary or under the 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 Guarantors, 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 governing the exercise of the rights of a Holder of any Note.

(b) Registration, Registration of Transfer and Exchange and Legends. The Issuer shall cause to be kept at the Corporate Trust Office of the Trustee a register (the register maintained in such office and in any other office or agency designated pursuant to Section 11.2 being herein sometimes collectively referred to as the “Note Register”) in which, subject to such reasonable regulations as they may prescribe, the Issuer shall provide for the registration of Notes and of transfers and exchanges of Notes. The Trustee is hereby appointed “Registrar” for the purpose of registering Notes and transfers and exchanges of Notes as herein provided.

Upon surrender for registration of transfer of any Note at an office or agency of the Issuer designated pursuant to Section 11.2 for such purpose in accordance with the terms hereof, the Issuer shall, subject to the other provisions of this Section 3.4, execute, and the Trustee shall, upon receipt of an Issuer Order, authenticate and deliver, in the name of the designated transferee or transferees, one or more new Notes of any authorized denominations and of a like tenor and aggregate principal amount and bearing the applicable legends set forth in Section 2.2.

Subject to Section 3.4(c), at the option of the Holder, Notes may be exchanged for other Notes of any authorized denominations and of a like tenor and aggregate principal amount and bearing the applicable legend set forth in Section 2.2, if any, each such new Note having the benefit of the Guarantees executed by the Guarantors, upon surrender of the Note to be exchanged at such office or agency. Whenever any Note is so surrendered for exchange, the Issuer shall execute, and the Trustee shall, upon receipt of an Issuer Order, authenticate and deliver, the Note which the Holder making the exchange is entitled to receive.

The Trustee shall have no obligation or duty to monitor, determine or inquire as to compliance with U.S. securities laws, including but not limited to any restrictions on transfer imposed under this Indenture or under applicable law with respect to any transfer of any interest in any Note (including any transfers between or among Agent Members or beneficial owners of

41

interests 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 solely as to form with the express requirements hereof. Neither the Trustee nor any Agent shall have any responsibility or liability for any actions taken or not taken by the Depositary.

All Notes and the Guarantees issued upon any registration of transfer or exchange of Notes shall be the valid obligations of the Issuer and the Guarantors, evidencing the same debt, and entitled to the same benefits under this Indenture, as the Notes and the Guarantees endorsed thereon, respectively, surrendered upon such registration of transfer or exchange.

Every Note presented or surrendered for registration of transfer or for exchange shall (if so required by the Issuer or the Trustee) be duly endorsed, or be accompanied by a written instrument of transfer in form satisfactory to the Issuer and the Registrar duly executed, by the Holder thereof or his attorney duly authorized in writing.

No service charge shall be made to the Holder for any registration of transfer or exchange of Notes, but the Issuer or the Trustee may require payment of a sum sufficient to cover any tax or other governmental charge that may be imposed in connection with any registration of transfer or exchange of Notes, other than any transfer or exchange pursuant to Section 3.4, Section 10.5 or Section 11.5.

The Issuer and the Registrar shall not be required (i) to issue, register the transfer of or exchange any Note during a period beginning at the opening of business 15 days before the due date for any payment of principal in respect of the Notes selected for redemption under Section 4.6 and ending at the close of business on the day of such mailing, or (ii) to register the transfer of or exchange any Note so selected for redemption in whole or in part, except the unredeemed portion of any Note being redeemed in part.

All Notes, initially issued hereunder shall, upon issuance, bear the relevant legends specified in Section 2.2, if any, to be applied to such a Note and, in the case of the legend specifically required for the Restricted Global Note, such required legend shall not be removed unless the Issuer shall have delivered to the Trustee (and the Notes Registrar, if other than the Trustee) an Issuer Order which states that such Note may be issued without such legend thereon. If such legend has been removed from a Note as provided above, no other Note issued in exchange for all or any part of such Note shall bear such legend, unless the Issuer has reasonable cause to believe that such other Note is a “restricted security” within the meaning of Rule 144 of the Notes Act and instructs the Trustee to cause a legend to appear thereon:

(c) Certain Transfers and Exchanges. Upon presentation for transfer or exchange of any Note at the office of the Trustee, as Registrar, located in The City of New York, accompanied by a written instrument of transfer or exchange in the form approved by the Issuer (it being understood that, until notice to the contrary is given to Holders of Notes, the Issuer shall be deemed to have approved the form of instrument of transfer or exchange, if any, printed on any Note), executed by the registered Holder, in person or by such Holder’s attorney thereunto duly authorized in writing, and upon compliance with this Section 3.4, such Note shall be

42

transferred upon the Note Register, and a new Note shall be authenticated and issued in the name of the transferee. Notwithstanding any provision to the contrary herein or in the Notes, transfers of a Global Note, in whole or in part, and transfers of interests therein of the kind described in this Section 3.4 (c), shall only be made in accordance with this Section 3.4(c). Transfers and exchanges subject to this Section 3.4(c) shall also be subject to the other provisions of this Indenture that are not inconsistent with this Section 3.4(c).

(1) General. A Global Note may not be transferred, in whole or in part, to any Person other than the Depositary or a nominee thereof, and no such transfer to any such other Person may be registered; provided, however, that this clause (1) shall not prohibit any transfer of a Note that is issued in exchange for a Global Note but is not itself a Global Note. No transfer of a Note to any Person shall be effective under this Indenture or the Notes unless and until such Note has been registered in the name of such Person. Nothing in this clause (1) shall prohibit or render ineffective any transfer of a beneficial interest in a Global Note effected in accordance with the other provisions of this Section 3.4(c).

(2) Restricted Global Note to Regulation S Global Note. If the holder of a beneficial interest in the Restricted Global Note wishes at any time to transfer such interest to a Person who wishes to take delivery thereof in the form of a beneficial interest in the Regulation S Global Note, such transfer may be effected, subject to the rules and procedures of the Depositary, Euroclear and Clearstream, in each case to the extent applicable and as in effect from time to time (the “Applicable Procedures”), only in accordance with this clause (2). Upon receipt by the Trustee, as Registrar, of (A) written instructions given by or on behalf of the Depositary in accordance with the Applicable Procedures directing the Trustee to credit or cause to be credited to a specified Agent Member’s account a beneficial interest in the Regulation S Global Note in a specified principal amount and to cause to be debited from another specified Agent Member’s account a beneficial interest in the Restricted Global Note in an equal principal amount and (B) a certificate in substantially the form set forth in Exhibit A signed by or on behalf of the Agent Member holding such beneficial interest in the Restricted Global Note, the Trustee, as Registrar, shall reduce the principal amount of a Restricted Global Note, and increase the principal amount of the Regulation S Global Note by such specified principal amount as provided in Section 3.4(a)(3).

(3) Regulation S Global Note to Restricted Global Note. If the holder of a beneficial interest in the Regulation S Global Note at any time wishes to transfer such interest to a Person who wishes to take delivery thereof in the form of a beneficial interest in the Restricted Global Note, such transfer may be effected, subject to the Applicable Procedures, only in accordance with this clause (3). Upon receipt by the Trustee, as Registrar, of (A) written instructions given by or on behalf of the Depositary in accordance with the Applicable Procedures directing the Trustee to credit or cause to be credited to a specified Agent Member’s account a beneficial interest in the Restricted Global Note in a specified principal amount and to cause to be debited from another specified Agent Member’s account a beneficial interest in the Regulation S Global Note and (B) a certificate in substantially the form set forth in Exhibit B signed by or on behalf of the Agent Member holding such beneficial interest in the Regulation S Global Note, the Trustee, as Registrar, shall reduce the principal amount of such Regulation S Global Note and increase the principal amount of the Restricted Global Note by such specified principal amount as provided in Section 3.4(a)(3).

43

(4) Non-Global Restricted Note to Global Note. If the holder of a Restricted Note (other than a Global Note) wishes at any time to transfer all or any portion of such Note to a Person who wishes to take delivery thereof in the form of a beneficial interest in the Restricted Global Note or the Regulation S Global Note, such transfer may be effected, subject to the Applicable Procedures, only in accordance with this clause (4). Upon receipt by the Trustee, as Registrar, of (A) such Note and written instructions given by or on behalf of such Holder as provided in Section 3.4(b) directing the Trustee to credit or cause to be credited to a specified Agent Member’s account a beneficial interest in the Restricted Global Note or the Regulation S Global Note, as the case may be, in a specified principal amount equal to the principal amount of the Restricted Note (or portion thereof) to be so transferred, and (B) an appropriately completed certificate substantially in the form set forth in Exhibit C-1 hereto, if the specified account is to be credited with a beneficial interest in the Restricted Global Note, or Exhibit C-2 hereto, if the specified account is to be credited with a beneficial interest in the Regulation S Global Note, signed by or on behalf of such Holder, then the Trustee, as Registrar, shall cancel such Restricted Note (and issue a new Note in respect of any untransferred portion thereof) as provided in Section 3.4(b) and increase the principal amount of the Restricted Global Note or Regulation S Global Note, as the case may be, by the specified principal amount as provided in Section 3.4(a)(3).

(5) Non-Global Regulation S Note to Restricted Global Note or Regulation S Global Note. If the Holder of a Regulation S Note (other than a Global Note) wishes at any time to transfer all or any portion of such Note to a Person who wishes to take delivery thereof in the form of a beneficial interest in the Restricted Global Note or the Regulation S Global Note, as the case may be, such transfer may be effected only in accordance with this clause (5) and subject to the Applicable Procedures. Upon receipt by the Trustee, as Registrar, of (A) such Note and written instructions given by or on behalf of such Holder as provided in Section 3.4(b) directing the Trustee to credit or cause to be credited to a specified Agent Member’s account a beneficial interest in the Restricted Global Note or the Regulation S Global Note, as the case may be, in a principal amount equal to the principal amount of the Note (or portion thereof) to be so transferred, and (B)(i) with respect to a transfer which is to be delivered in the form of a beneficial interest in the Restricted Global Note, a certificate in substantially the form set forth in Exhibit D-l, signed by or on behalf of such Holder, and (ii) with respect to a transfer which is to be delivered in the form of a beneficial interest in the Regulation S Global Note, a certificate in substantially the form set forth in Exhibit D-2, signed by or on behalf of such Holder, then the Trustee, as Registrar, shall cancel such Note (and issue a new Note in respect of any untransferred portion thereof) as provided in Section 3.4(b) and increase the principal amount of the Restricted Global Note or the Regulation S Global Note, as the case may be, by the specified principal as provided in Section 3.4(a)(3).

Section 3.5. Mutilated, Destroyed, Lost and Stolen Notes.

If any mutilated or defaced Note is surrendered to the Trustee, the Issuer shall execute and the Trustee shall, upon receipt of an Issuer Order, authenticate or cause to be authenticated and deliver in exchange therefor a new Note of like tenor and principal amount, having endorsed thereon the Guarantees executed by the Guarantors and bearing a number not contemporaneously outstanding.

If there shall be delivered to the Issuer and the Trustee (i) evidence to their satisfaction of the destruction, loss or theft of any Note and (ii) such security or indemnity as may be required by them to save each of them, the Guarantors and any agent of either of them harmless, then, in the absence of notice to the Issuer or the Trustee that such Note has been acquired by a bona fide purchaser, the Issuer shall execute and the Trustee shall, upon receipt of an Issuer Order, authenticate and deliver, in lieu of any such destroyed, lost or stolen Note, a new Note of like tenor and principal amount, having endorsed thereon the Guarantees executed by the Guarantors and bearing a number not contemporaneously outstanding.

In case any such mutilated, defaced, destroyed, lost or stolen Note has become or is about to become due and payable, the Issuer may in its discretion, instead of issuing a new Note, pay such Note.

Upon the issuance of any new Note under this Section, the Issuer may require the payment of a sum sufficient to cover any tax or other governmental charge that may be imposed in relation thereto and any other expenses (including the fees and expenses of the Trustee, its counsel, the Registrar and the Paying Agents) connected therewith.

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

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

Section 3.6. Payment of Interest; Interest Rights Preserved.

Interest on any Note which is payable, and is punctually paid or duly provided for, on any Interest Payment Date shall be paid to the Person in whose name that Note (or one or more Predecessor Notes) is registered at the close of business on the Record Date for such interest.

Any interest on any Note which is payable, but is not punctually paid or duly provided for, on any Interest Payment Date (herein called “Defaulted Interest”) shall (a) bear interest at the rate per annum stated in the form of Note included herein, (to the extent that the payment of such interest shall be legally enforceable), and (b) forthwith cease to be payable to the Holder on the relevant Record Date by virtue of having been such Holder, and such Defaulted Interest may be paid by the Issuer, at its election in each case, as provided in clause (1) or (2) below:

45

(1) the Issuer may elect to make payment of any Defaulted Interest to the Persons in whose names the Notes (or their respective Predecessor Notes) are registered at the close of business on a Special Record Date for the payment of such Defaulted Interest, which shall be fixed in the following manner. The Issuer shall notify the Trustee in writing of the amount of Defaulted Interest proposed to be paid on each Note and the date of the proposed payment, and at the same time the Issuer shall deposit with the Trustee an amount of money equal to the aggregate amount proposed to be paid in respect of such Defaulted Interest or shall make arrangements satisfactory to the Trustee for such deposit prior to the date of the proposed payment, such money when deposited to be held in trust for the benefit of the Persons entitled to such Defaulted Interest as in this clause provided.

Thereupon the Trustee shall fix a Special Record Date for the payment of such Defaulted Interest which shall be not more than 15 days and not less than 10 days prior to the date of the proposed payment and not less than 10 days after the receipt by the Trustee of the notice of the proposed payment. The Trustee shall promptly notify the Issuer of such Special Record Date and, in the name and at the expense of the Issuer, shall cause notice of the proposed payment of such Defaulted Interest and the Special Record Date therefor to be mailed, first-class postage prepaid, to each Holder at his address as it appears in the Note Register, not less than 10 days prior to such Special Record Date. Notice of the proposed payment of such Defaulted Interest and the Special Record Date therefor having been so mailed, such Defaulted Interest shall be paid to the Persons in whose names the Notes (or their respective Predecessor Notes) are registered at the close of business on such Special Record Date and shall no longer be payable pursuant to the following clause (2); and

(b) the Issuer may make payment of any Defaulted Interest in any other lawful manner not inconsistent with the requirements of any securities exchange on which the Notes may be listed, and upon such notice as may be required by such exchange, if, after notice given by the Issuer to the Trustee of the proposed payment pursuant to this clause, such manner of payment shall be deemed practicable by the Trustee.

Subject to the foregoing provisions of this Section, each Note delivered under this Indenture upon registration of transfer of or in exchange for or in lieu of any other Note shall carry the rights to interest accrued and unpaid, and to accrue, which were carried by such other Note.

Section 3.7. Persons Deemed Owners.

Prior to due presentment of a Note for registration of transfer and the effective registration of such transfer by the Registrar, the Issuer, the Guarantors, the Trustee and any agent of the Issuer, the Guarantors or the Trustee may treat the Person in whose name such Note is registered as the owner of such Note for the purpose of receiving payment of principal of and premium, if any, and (subject to Section 3.6) interest on such Note and for all other purposes whatsoever, whether or not such Note be overdue, and none of the Issuer, the Guarantors, the Trustee or any agent of the Issuer, the Guarantors or the Trustee shall be liable for so treating such Holder.

46

Section 3.8. Cancellation.

Except as provided for in Section 4.2 and 4.3, Notes surrendered for payment, redemption, registration of transfer or exchange shall, if surrendered to any Person other than the Trustee, be delivered to the Trustee and shall be promptly cancelled by it. The Issuer may at any time deliver to the Trustee for cancellation, accompanied by an Issuer Order, any Notes previously authenticated and delivered hereunder which the Issuer may have acquired in any manner whatsoever, and all Notes so delivered shall be promptly cancelled by the Trustee. No Notes shall be authenticated in lieu of or in exchange for any Notes cancelled as provided in this Section, except as expressly permitted by this Indenture. All cancelled Notes held by the Trustee shall be disposed of in accordance with its standard procedures or as directed by an Issuer Order; provided, however, that the Trustee shall not be required to destroy such Notes.

Section 3.9. Computation of Interest.

The amount of interest payable on the Notes for any interest period will be calculated by applying the rate of interest to the principal amount of such Note, on the basis of a year of 360 days consisting of 12 months of 30 days each and, in the case of an incomplete month, on the number of days elapsed based on a 30 day month provided, however, that Defaulted Interest shall be computed on the basis of a 365 or 366-day year, as the case may be, and the number of days actually elapsed.

Section 3.10. CUSIP Numbers.

The Issuer shall in issuing the Notes use CUSIP numbers, and the Trustee shall use the applicable CUSIP number in notices of redemption or exchange as a convenience to the Holders; provided, that any such notice may state that no representation is made as to the accuracy or correctness of the CUSIP number or numbers printed in the notice or on the certificates representing the Notes and that reliance may be placed only on the other identification numbers printed on the certificates representing the Notes. The Issuer shall promptly notify the Trustee in writing of any change in CUSIP numbers.

Section 3.11. Paying Agents; Discharge of Payment Obligations; Indemnity of Holders.

(a) The Issuer may from time to time appoint one or more paying agents under this Indenture and the Notes. By its execution and delivery of this Indenture, the Issuer hereby initially designates and appoints The Bank of New York Mellon, as Principal Paying Agent. Subject to Section 11.3, the Issuer or a Guarantor may act as paying agent.

(b) Unless the Issuer or a Guarantor shall be acting as paying agent as provided in Section 11.3, the Issuer shall, by 11:00 a.m. New York City time, no later than one Business Day prior to each Interest Payment Date, Redemption Date or Maturity Date on any Notes (whether on maturity, redemption or otherwise) (each, a “Payment Date”), deposit with the Principal Paying Agent in immediately available funds a sum sufficient to pay such principal, any

47

premium, and interest when so becoming due (including any Additional Amounts). The Issuer shall request that the bank through which such payment is to be made agree to supply to the Principal Paying Agent in New York City by 11:00 a.m. (New York City time) two Business Days prior to the due date for any such payment an irrevocable confirmation (by authenticated SWIFT MT 100 Message) of its intention to make such payment. The Principal Paying Agent shall arrange with all other Paying Agents for the payment, from funds furnished by the Issuer or the Guarantors to the Principal Paying Agent pursuant to this Indenture, of the principal, and premium, if any, and interest (including Additional Amounts, if any) on the Notes and of the compensation of such Paying Agents for their services as such.

All Paying Agents will hold in trust, for the benefit of Holders or the Trustee, all money held by such Paying Agent for the payment of principal, or premium if any, of or interest on the Notes and shall notify the Trustee in writing of any default by the Issuer in making any such payment. 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 it. Upon complying with this Section 3.11 and the applicable provisions of Section 11.3, the Paying Agents shall have no further liability for the money delivered to the Trustee.

(c) Any payment to be made in respect of the Notes or the Guarantees by the Issuer or the Guarantors, as the case may be, to or to the order of any Paying Agent shall be in satisfaction pro tanto of the obligations of the Issuer under the Notes.

(d) Each payment in full of principal, redemption amount, Additional Amounts and/or interest payable under this Indenture in respect of any Note made by or on behalf of the Issuer to or to the order of any Paying Agent in the manner specified in this Indenture on the date due shall be valid and effective to satisfy and discharge the obligation of the Issuer to make payment of principal, redemption amount, Additional Amounts and/or interest payable under this Indenture on such date, provided, however, that the liability of any Paying Agent hereunder shall not exceed any amounts paid to it by the Issuer, or held by it, on behalf of the Holders under this Indenture; and provided further that, in the event that there is a default by the Paying Agent or the Principal Paying Agent in any payment of principal, redemption amount, Additional Amounts and/or interest in respect of any Note in accordance with this Indenture, the Issuer and the Guarantors shall pay on demand such further amounts as will result in receipt by the Holder of such amounts as would have been received by it had no such default. This obligation constitutes a separate and independent obligation from the other obligations of the Issuer under the Notes and the Guarantors under the Guarantees, shall give rise to a separate and independent cause of action, will apply irrespective of any waiver granted by the Trustee and/or any Holder of Notes and shall continue in full force and effect despite any judgment, order, claim, or proof for a liquidated amount in respect of any sum due under this Indenture, the Notes or any judgment or order.

Article IV

REDEMPTION OF NOTES

Section 4.1. Redemption for Tax Reasons.

If as a result of any Change of Law (as defined below):

(1) the Issuer or a Guarantor is or would be required on the next succeeding Interest Payment Date to pay any Additional Amounts in excess of the Additional Amounts that the Issuer or such Guarantor, as the case may be, would pay if payments in respect of the Notes were subject to deduction or withholding for Taxes imposed by the applicable taxing jurisdiction at the rate applicable on the Issue Date; or

(2) the issuers/borrowers of certain intercompany debt are or would be required on the next succeeding interest payment date to pay Brazilian withholding taxes in excess of a general rate of 15%, or 25% in case of amounts paid to residents of countries or locations which do not impose any income tax or which impose it at a maximum rate lower than 17% or where the laws of that country or location impose restrictions on the disclosure (x) of shareholding composition; (y) of the ownership of the investment; or (z) to the identification of the beneficial owner of income attributed to non-resident persons, pursuant to article 8 of Law No. 9,779, of January 19, 1999, and articles 24 and 24-A of Law No. 9,430, of December 27, 1996; provided that, such requirement to pay such taxes in excess of such rate was not caused by, or otherwise the result of, whether directly or indirectly, wholly or in part, any amendment to the intercompany debt,

and in either case, the payment of such excess amounts cannot be avoided by the use of any reasonable measures available to the Issuer or a Guarantor, the Notes may be redeemed, by the Issuer at the option of the Issuer or a Guarantor, in whole but not in part, upon not less than 30 nor more than 90 days’ notice to the Holders, which notice will be published, at any time following such Change of Law at a Redemption Price equal to the principal amount thereof, plus accrued and unpaid interest, if any, to the date fixed for redemption. The Issuer, any Guarantor or any of their respective Affiliates will also pay to the Holders of the Notes on the Redemption Date any Additional Amounts which are payable. Following such redemption, the Notes will be cancelled, or remain Outstanding, at the Issuer’s or a Guarantor’s election.

“Change of Law” means any change in or amendment to the laws or regulations of Luxembourg, Brazil or Peru (or of any political subdivision thereof or therein) or the adoption, amendment or modification of any resolution of the Central Bank of Luxembourg, the Central Bank of Brazil or the Central Reserve Bank of Peru (or any successor authority thereto) which becomes effective on or after the date of this Indenture (or with respect to a successor, on or after the date such successor assumes the obligations under the Notes), resulting in the Issuer or a Guarantor on a consolidated basis being required to pay amounts with respect to Taxes as described above in a total aggregate amount in excess of that payable immediately prior to such change or amendment.

49

Prior to the delivery of any notice of redemption in accordance with the foregoing, the Issuer or a Guarantor shall deliver to the Trustee and the Agents an Officer’s Certificate stating that the Issuer or a Guarantor, as the case may be, is entitled to effect such redemption based on an Opinion of Counsel or written advice of a qualified tax expert, that the Issuer or a Guarantor has or will become obligated to pay such excess amounts with respect to Taxes as a result of such Change of Law. Such notice, once delivered by the Issuer or a Guarantor to the Trustee, will be irrevocable.

If the Issuer or a Guarantor becomes subject at any time to any taxing jurisdiction other than Luxembourg, Brazil or Peru, references herein to Luxembourg, Brazil or Peru, as applicable, shall be construed to include such other jurisdiction.

Section 4.2. Optional Redemption.

At any time before January 9, 2034 (which is the date that is three months prior to maturity of the notes (the “Par Call Date”)), the Issuer or a Guarantor has the right to redeem the Notes, in whole or in part and from time to time, at a Redemption Price equal to the greater of (1) 100% of the principal amount of the Notes being redeemed and (2) the sum of the present values of the remaining scheduled payments of principal and interest on the Notes being redeemed that would be due if the Notes matured on the Par Call Date (inclusive of interest accrued to the redemption date), discounted to the Redemption Date on a semi-annual basis (assuming a 360-day year consisting of twelve 30-day months) at the Treasury Rate plus 40 basis points, less interest accrued to, but excluding, the Redemption Date; plus, in either case, accrued and unpaid interest on the principal amount of the Notes being redeemed and Additional Amounts, if any, to, but excluding, 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).

At any time on or after the Par Call Date, the Issuer or a Guarantor has the right to redeem the Notes, in whole or in part and from time to time, at a Redemption Price equal to 100% of the principal amount of the Notes being redeemed plus accrued and unpaid interest on the principal amount of the Notes being redeemed to, but excluding, such 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).

The “Treasury Rate” shall be determined by the Issuer or a Guarantor after 4:15 p.m., New York City time (or after such time as yields on U.S. government securities are posted daily by the Board of Governors of the Federal Reserve System), on the third Business Day preceding the Redemption Date based upon the yield or yields for the most recent day that appear after such time on such day in the most recent statistical release published by the Board of Governors of the Federal Reserve System designated as “Selected Interest Rates (Daily) - H.15” (or any successor designation or publication) (“H.15”) under the caption “U.S. government securities–Treasury constant maturities–Nominal” (or any successor caption or heading). In determining the Treasury Rate, the Issuer or a Guarantor shall select, as applicable: (i) the yield for the Treasury constant maturity on H.15 exactly equal to the period from the redemption date to the Par Call Date (the “Remaining Life”); or (ii) if there is no such Treasury constant maturity on H.15 exactly equal to the Remaining Life, the two yields – one yield corresponding to the Treasury constant maturity on H.15 immediately shorter than and one yield corresponding to the Treasury

50

constant maturity on H.15 immediately longer than the Remaining Life – and shall interpolate to the Par Call Date on a straight-line basis (using the actual number of days) using such yields and rounding the result to three decimal places; or (iii) if there is no such Treasury constant maturity on H.15 shorter than or longer than the Remaining Life, the yield for the single Treasury constant maturity on H.15 closest to the Remaining Life. For purposes of this paragraph, the applicable Treasury constant maturity or maturities on H.15 shall be deemed to have a maturity date equal to the relevant number of months or years, as applicable, of such Treasury constant maturity from the Redemption Date.

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

The Issuer or a Guarantor’s actions and determinations in determining the Redemption Price shall be conclusive and binding for all purposes, absent manifest error.

The Issuer, any Guarantor or any of their respective Affiliates may at any time repurchase the Notes at any price in the open market or otherwise. The Issuer, any Guarantor or any of their respective Affiliates may hold or resell the Notes it purchases or may surrender them to the Trustee or an Agent for cancellation.

Optional Clean-up Redemption. Notwithstanding the foregoing, in connection with any tender offer for the notes (including an Offer to Purchase in connection with a Change of Control that results in a Rating Decline made in accordance with the terms of the Indenture), in the event that the Holders of not less than 85% of the aggregate principal amount of the outstanding Notes validly tender and do not validly withdraw Notes in such tender offer and the Issuer, or any other Person making such offer in lieu of the Issuer, purchases all of the Notes validly tendered and not validly withdrawn by such Holders, then the Issuer or the Guarantor will have the right, on not less than 10 nor more than 60 days’ prior notice to the Holders (with a copy to the Trustee), to redeem all of the Notes that remain outstanding at a Redemption Price equal to the purchase price paid to each other Holder in such tender offer plus, to the extent not included in the purchase price, accrued and unpaid interest and Additional Amounts, if any, on the Notes that remain outstanding, to, but excluding, the Redemption Date.

51

Section 4.3. Applicability of Article.

Redemption of Notes at the election of the Issuer, as permitted or required by any provision of this Indenture, shall be made in accordance with such provision and this Article.

Section 4.4. Election to Redeem; Notice to Trustee, Registrar and Paying Agent.

In the case of any redemption of Notes prior to the expiration of any restriction on such redemption provided in the terms of such Notes or elsewhere in this Indenture, the Issuer shall furnish the Trustee with an Officer’s Certificate evidencing compliance with such restriction.

The Issuer shall provide notice of redemption to the Trustee, Registrar and Paying Agents at least 15 days (or such shorter period as agreed to by the Trustee) prior to when such notice of redemption shall be provided to the Holders.

Section 4.5. Notice of Redemption.

Notice of redemption pursuant to Section 4.1 and 4.2 hereof shall be given in the manner provided for in Section 1.6 hereof. The Trustee, Registrar and Paying Agent will notify the Holders at such Holder’s address appearing in the Note register at least 10 but not more than 60 days prior to the Redemption Date. A notice of any redemption may, at the Issuer’s or a Guarantor’s discretion, be subject to one or more conditions precedent.

All notices of redemption shall state:

(1) the Redemption Date;

(2) the Redemption Price;

(3) that on the Redemption Date, the Redemption Price will become due and payable upon each such Note to be redeemed and that interest thereon will cease to accrue on and after said date;

(4) the place or places where such Notes are to be surrendered for payment of the Redemption Price;

(5) the aggregate principal amount of Notes being redeemed;

(6) the CUSIP number or numbers of the Notes being redeemed;

(7) if fewer than all the outstanding Notes are to be redeemed, or if a Note is to be redeemed in part only, the identification and principal amounts at maturity of the particular Notes (or portion thereof) to be redeemed; and

52

(8) that no representation is made as to the correctness or accuracy of the CUSIP numbers, if any, listed in such notice or printed on the Notes.

Section 4.6. Deposit of Redemption Price.

By 11:00 a.m. (New York City time) on the Business Day prior to any Redemption Date, the Issuer or a Guarantor shall deposit with the Principal Paying Agent (or, if the Issuer is acting as its own Paying Agent, segregate and hold in trust as provided in Section 11.3) an amount of money sufficient to pay the Redemption Price on all of the Notes which are to be repurchased on that date. In the case of a partial redemption of Notes that are represented by a Global Note, the relevant Notes will be redeemed in accordance with the rules of DTC.

Section 4.7. Notes Payable on Redemption Date.

Notice of redemption having been given as aforesaid, the Notes so to be redeemed shall, on the Redemption Date, become due and payable at the Redemption Price therein specified, and from and after such date (unless the Issuer shall default in the payment of the Redemption Price and accrued and unpaid interest) such Notes shall cease to bear interest. Upon surrender of any such Note for redemption in accordance with said notice, such Note shall be paid by the Issuer at the Redemption Price, together with accrued and unpaid interest to the Redemption Date; provided, however, that installments of interest whose Maturity Date is on or prior to the Redemption Date shall be payable to the Holders of such Notes, or one or more Predecessor Notes, registered as such at the close of business on the relevant Record Dates according to their terms and the provisions of Section 3.7.

If any Note called for redemption shall not be so paid upon surrender thereof for redemption, the principal (and premium, if any) shall, until paid, bear interest from the Redemption Date at the rate provided by the Note.

Article V

(6) all or substantially all of the assets of the Issuer (on a consolidated basis) shall be condemned, seized or otherwise appropriated, or custody of such property shall be assumed by any governmental authority or court or other person purporting to act under the authority of the federal government of any jurisdiction, or the Issuer shall be prevented from exercising normal control over all or substantially all of its property or revenues (on a consolidated basis), if the whole or part of such property or revenues is material to the Issuer (on a consolidated basis);

(7) (a) a secured party takes possession of all or substantially all the assets or revenues of the Issuer (on a consolidated basis) or (b) a receiver or similar officer is appointed, of all or substantially all the assets or revenues of the Issuer (on a consolidated basis);

(8) the Issuer or any Guarantor pursuant to or under or within the meaning of any Bankruptcy Law (a) commences a voluntary case or proceeding; (b) consents to the making of a Bankruptcy Order in an involuntary case or proceeding or the

(10) any of the Guarantees is not (or is claimed by any Guarantor not to be) in full force and effect.

If any Event of Default shall occur and be continuing, either (i) the Trustee or (ii) the Holders, with written notice to the Trustee, of at least 25% in aggregate principal amount of the Outstanding Notes may accelerate the maturity of all Notes; provided that, after such acceleration, but before a judgment or decree based on acceleration, the Holders of a majority in aggregate principal amount of Outstanding Notes may, as provided in Section 6.12, rescind and annul such acceleration if all Events of Default, other than the nonpayment of accelerated principal, have been cured or waived as provided in this Indenture. The Trustee shall not be deemed to have notice of any Default or Event of Default (other than a payment default) unless a Responsible Officer of the Trustee has actual knowledge thereof or unless written notice of any event which is in fact such a default is received by a Responsible Officer of the Trustee at the Corporate Trust Office of the Trustee, and such notice references the Notes and this Indenture. If an Event of Default specified in clause (8) above occurs with respect to the Issuer, the Outstanding Notes will ipso facto become immediately due and payable without any declaration or other act on the part of the Trustee or any Holder.

Section 6.2. Collection of Indebtedness and Suits for Enforcement by Trustee. The Issuer and the Guarantors covenant that if

(1) default is made in the payment of any interest on any Note, (including Additional Amounts, if any), when such amounts become due and payable and such default continues for a period of 30 days; or

(2) default is made in the payment of the principal of (or premium, if any, on) any Note at the Maturity thereof or, with respect to any Note to be redeemed, at the Redemption Date thereof,

the Issuer and the Guarantors (subject to the limitations provided in this Indenture) will, jointly and severally, upon demand of the Trustee, pay to it, for the benefit of the Holders of such Notes, the whole amount then due and payable on such Notes for principal (and premium, if any) and interest (including Additional Amounts, if any), and, to the extent that payment of interest on overdue amounts shall be legally enforceable, interest on any overdue principal (and premium, if any) and on any overdue interest, at the rate provided by the Notes, and, in addition thereto, such further amount as shall be sufficient to cover the costs and expenses incurred by the Trustee

56

under this Indenture, including the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel.

If the Issuer and the Guarantors fail to pay such amounts forthwith upon such demand, the Trustee, in its own name and as trustee of an express trust, may institute a judicial proceeding for the collection of the sums so due and unpaid, may prosecute such proceeding to judgment or final decree, and may enforce the same against the Issuer, the Guarantors or any other obligor upon the Notes and collect the moneys adjudged or decreed to be payable in the manner provided by law out of the property of the Issuer, the Guarantors or any other obligor upon the Notes, wherever situated.

If an Event of Default occurs and is continuing, the Trustee may in its discretion proceed to protect and enforce its rights and the rights under this Indenture of the Holders by such appropriate judicial proceedings as the Trustee shall deem most effective to protect and enforce any such rights, whether for the specific enforcement of any covenant or agreement in this Indenture or in aid of the exercise of any power granted herein including, without limitation, seeking recourse against the Issuer or the Guarantors or proceeding to enforce any other proper remedy.

Section 6.3. Trustee May File Proofs of Claim.

The Trustee may file such proofs of claim and other papers or documents as may be necessary or advisable in order to have the claims of the Trustee and the Holders allowed in any judicial proceedings relative to the Issuer, the Guarantors, their respective creditors or its property and, unless prohibited by law or applicable regulations, may vote on behalf of the Holders at their direction 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 pay to the Trustee any amount due it for the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and its counsel, and any other amounts due the Trustee under Section 7.7.

Section 6.4. Trustee May Enforce Claims Without Possession of Notes.

All rights of action and claims under this Indenture or the Notes may be prosecuted and enforced by the Trustee without the possession of any of the Notes or the production thereof in any proceeding relating thereto, and any such proceeding instituted by the Trustee shall be brought in its own name as trustee of an express trust, and any recovery of judgment shall, after provision for the payment of the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel, be for the ratable benefit of the Holders of the Notes in respect of which such judgment has been recovered.

Section 6.5. Application of Money Collected.

Any money collected by the Trustee pursuant to this Article shall be applied in the following order, at the date or dates fixed by the Trustee and, in case of the distribution of such money on account of principal (or premium, if any) or interest, upon presentation of the Notes

57

and the notation thereon of the payment if only partially paid and upon surrender thereof if fully paid;

| FIRST: | To the payment of all amounts due to the Trustee and the Agents under this Indenture; and

| SECOND: | To the payment of the amounts then due and unpaid for principal of (and premium, if any) and interest on the Notes in respect of which or for the benefit of which such money has been collected, ratably, without preference or priority of any kind, according to the amounts due and payable on such Notes for principal (and premium, if any) and interest, respectively.

The Trustee, upon prior written notice to the Issuer, may fix a Record Date and payment date for any payment to the Holders pursuant to this Section 6.5.

Section 6.6. Limitation on Suits.

No Holder of any Note shall have any right to institute any proceeding, judicial or otherwise, with respect to this Indenture, or for the appointment of a receiver or trustee, or for any other remedy hereunder, unless:

(1) such Holder shall have previously given written notice to the Trustee of a continuing Event of Default;

(2) the Holders of at least 25% in aggregate principal amount of the Outstanding Notes shall have made written request to the Trustee to institute proceedings in respect of such Event of Default in its own name as Trustee hereunder and shall have offered to the Trustee indemnity and/or security reasonably satisfactory to the Trustee against the costs, expenses and liabilities to be incurred in compliance with such request;

(3) the Trustee for 60 days after its receipt of such notice, request and offer shall have failed to institute any such proceeding; and

(4) no direction inconsistent with such written request shall have been given to the Trustee during such 60-day period by the Holders of a majority in principal amount of the Outstanding Notes;

it being understood and intended that no one or more Holders shall have any right in any manner whatever by virtue of, or by availing of, any provision of this Indenture or any Note or the Guarantees to affect, disturb or prejudice the rights of any other Holders, or to obtain or to seek to obtain priority or preference over any other Holders or to enforce any right under this Indenture (it being understood that the Trustee does not have an affirmative duty to ascertain whether or not such actions or forbearances are unduly prejudicial to such Holders), any Note or the Guarantees, except in the manner herein provided and for the equal and ratable benefit of all the Holders.

58

Section 6.7. Unconditional Right of Holders to Receive Principal, Premium and Interest.

Notwithstanding any other provision in this Indenture, the Notes or the Guarantees, the Holder of any Note shall have the right, which is absolute and unconditional, to receive payment of the principal of (and premium, if any) and (subject to Section 3.6) interest on such Note on the respective Stated Maturities expressed in such Note (or earlier Redemption Date) and to institute suit for the enforcement of any such payment, and such rights shall not be impaired without the consent of such Holder.

Section 6.8. Restoration of Rights and Remedies.

If the Trustee or any Holder has instituted any proceeding to enforce any right or remedy under this Indenture, any Note or the Guarantees, and such proceeding has been discontinued or abandoned for any reason, or has been determined adversely to the Trustee or to such Holder, then and in every such case, subject to any determination in such proceeding, the Issuer, the Guarantor, the Trustee and the Holders shall be restored severally and respectively to their former positions hereunder and thereafter all rights and remedies of the Trustee and the Holders shall continue as though no such proceeding had been instituted.

Section 6.9. Rights and Remedies Cumulative.

Except as otherwise provided with respect to the replacement or payment of mutilated, destroyed, lost or stolen Notes in the last paragraph of Section 3.5 hereof, no right or remedy herein conferred upon or reserved to the Trustee or to the Holders is intended to be exclusive of any other right or remedy, and every right and remedy shall, to the extent permitted by law, be cumulative and in addition to every other right and remedy given hereunder or now or hereafter existing at law or in equity or otherwise. The assertion or employment of any right or remedy hereunder, or otherwise, shall not prevent the concurrent assertion or employment of any other appropriate right or remedy.

Section 6.10. Delay or Omission Not Waiver.

No delay or omission of the Trustee or of any Holder of any Note to exercise any right or remedy accruing upon any Event of Default shall impair any such right or remedy or constitute a waiver of any such Event of Default or an acquiescence therein. Every right and remedy given by this Article or by law to the Trustee or to the Holders may be exercised from time to time, and as often as may be deemed expedient, by the Trustee or by the Holders, as the case may be.

Section 6.11. Control by Holders.

The Holders of a majority of the aggregate principal amount of the Outstanding Notes shall have the right to direct the time, method and place of conducting any proceeding for any remedy available to the Trustee or exercising any trust or power conferred on the Trustee, provided that:

59

(1) such direction shall not be in conflict with any rule of law or with this Indenture or expose the Trustee to personal liability (as determined in the sole discretion of the Trustee); and

(2) the Trustee may take any other action deemed proper by the Trustee which is not inconsistent with such direction.

The Trustee may refuse, however, to follow any direction that the Trustee, in its sole discretion, determines may be unduly prejudicial to the rights of the Holders or that may subject the Trustee to any liability, loss or expense if the Trustee determines, in its sole discretion, that it lacks satisfactory indemnification and/or security against such liability, loss or expense.

Section 6.12. Waiver of Past Defaults.

The Holders of not less than a majority in aggregate principal amount of the Outstanding Notes may by written notice to the Issuer and the Trustee waive any past default hereunder and rescind and annul any declaration of acceleration and its consequences, except a default:

(1) in the payment of the principal of (or premium, if any) or interest on any Note; or

(2) in respect of a covenant or provision hereof which under Article X cannot be modified or amended without the consent of the Holder of each Outstanding Note affected.

Upon any such waiver, such default shall cease to exist, and any Event of Default arising therefrom shall be deemed to have been cured, for every purpose of this Indenture; but no such waiver shall extend to any subsequent or other default or impair any right consequent thereon.

Section 6.13. Undertaking for Costs.

In any suit for the enforcement of any right or remedy under this Indenture or in any suit against the Trustee for any action taken or omitted by it as a Trustee, a court in its discretion may require the filing by any party litigant in the suit of an undertaking to pay the costs of the suit, and the court in its discretion may assess reasonable costs, including reasonable attorney’s 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 6.13 does not apply to a suit by the Trustee, a suit by a Holder pursuant to Section 6.7 hereof, or a suit by Holders of more than 10% in principal amount of the then Outstanding Notes.

Article VII
THE TRUSTEE

Section 7.1. Certain Duties and Responsibilities.

(a) Except during the continuance of an Event of Default,

60

(1) the Trustee undertakes to perform solely such duties and only such duties as are specifically set forth in this Indenture, and 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

(2) in the absence of gross negligence on its part, the Trustee may conclusively rely, as to the truth of the statements and the correctness of the opinions expressed therein, upon certificates or opinions furnished to the Trustee and conforming to the requirements of this Indenture; but 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 to the form requirements of this Indenture (but need not confirm or investigate the accuracy of mathematical calculations or other facts stated therein).

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

(c) No provision of this Indenture shall be construed to relieve the Trustee from liability for its own grossly negligent action or its own willful misconduct, except that:

(1) this Subsection shall not be construed to limit the effect of Subsection (a) of this Section;

(2) the Trustee shall not be liable for any error of judgment made in good faith by a Responsible Officer or Officers of the Trustee, unless it shall be proved that the Trustee was grossly negligent in ascertaining the pertinent facts;

(3) the Trustee shall not be liable with respect to any action taken or omitted to be taken by it in good faith in accordance with the direction of the Holders of a majority in principal amount of the Outstanding Note of any series, determined as provided in Section 6.2, relating to the time, method and place of conducting any proceeding for any remedy available to the Trustee, or exercising any trust or power conferred upon the Trustee, under this Indenture with respect to the Note;

(4) no provision of this Indenture shall require the Trustee to expend or risk its own funds or otherwise incur any 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 for believing that repayment of such funds or adequate indemnity and/or security against such risk or liability is not reasonably assured to it;

(5) the Trustee shall not be liable in respect of any payment (as to the correctness of amount, entitlement to receive or any other matters relating to payment) or notice effected by the Issuer or any Paying Agent or any records maintained by any co-Note Registrar with respect to the Notes;

61

(6) if any party fails to deliver a notice relating to an event the fact of which, pursuant to this Indenture, requires notice to be sent to the Trustee, the Trustee may conclusively rely on its failure to receive such notice as reason to act as if no such event occurred, unless a Responsible Officer of the Trustee had actual knowledge of such event;

(7) the delivery of any information to the Trustee under this Indenture, including but not limited to any Rule 144A information, or reports to the Trustee is for informational purposes only and the receipt of such information or reports by the Trustee shall not constitute constructive notice of any information contained therein;

(8) in the absence of written investment direction from the Issuer, all cash received by the Trustee shall be placed in a non-interest bearing trust account, and in no event shall the Trustee be liable for the selection of investments or for investment losses incurred thereon or for losses incurred as a result of the liquidation of any such investment prior to its maturity date or the failure of the party directing such investments prior to its maturity date or the failure of the party directing such investment to provide timely written investment direction, and the Trustee shall have no obligation to invest or reinvest any amounts held hereunder in the absence of such written investment direction from the Issuer;

(9) in the event that the Trustee is also acting as custodian, Registrar, Paying Agent, exchange agent, bid solicitation agent or transfer agent hereunder, the rights and protections afforded to the Trustee pursuant to this Article VII shall also be afforded to such custodian, Registrar, Paying Agent, exchange agent, bid solicitation agent or transfer agent;

(10) any application by the Trustee for written instructions from the Issuer (other than with regard to any action proposed to be taken or omitted to be taken by the Trustee that affects the rights of the Holders of the Notes under this Indenture) may, at the option of the Trustee, set forth in writing any action proposed to be taken or omitted by the Trustee under this Indenture and the date on and/or after which such action shall be taken or such omission shall be effective. The Trustee shall not be liable to the Issuer for any action taken by, or omission of, the Trustee in accordance with a proposal included in such application on or after the date specified in such application (which date shall not be less than three Business Days after the date any officer that the Issuer has indicated to the Trustee should receive such application actually receives such application, unless any such officer shall have consented in writing to any earlier date), unless, prior to taking any such action (or the effective date in the case of any omission), the Trustee shall have received written instructions in accordance with this Indenture in response to such application specifying the action to be taken or omitted.

(d) Whether or not therein expressly so provided, 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 this Section.

The Trustee shall give the Holders notice of any Default (“Notice of Default”) that has occurred and is continuing and of which a Responsible Officer of the Trustee has actual knowledge, within 90 days after the occurrence of such Default (but not less than 15 days after knowledge thereof). The Trustee may withhold from Holders notice of any continuing Default or Event of Default (except a Default or Event of Default relating to the payment of principal, premium, if any, or interest on, the Notes) if it determines that withholding such notice is in their interest; provided that, in the case of a default of a character specified in Section 6.1(4), no such notice to Holders shall be given until at least 30 days after the occurrence thereof.

Section 7.3. Certain Rights of Trustee and the Agents.

Subject to the provisions of Section 7.1:

(a) the Trustee and the Agents may rely conclusively and shall be protected in acting or refraining from acting upon any resolution, certificate, statement, instrument, opinion, report, notice, request, direction, consent, order, bond, debenture, note, other evidence of indebtedness or other paper or document believed by it to be genuine and to have been signed or presented by the proper party or parties;

(d) the Trustee or the Agents may consult with counsel of its selection, at the expense of the Issuer, and the advice of such counsel or any Opinion of Counsel shall be full and complete authorization and protection in respect of any action taken, suffered or omitted by it hereunder in good faith and in reliance thereon;

(e) the Trustee and each Agent shall 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 of the Holders pursuant to this Indenture, unless such Holders shall have offered to the Trustee or such Agent, as applicable, security and/or indemnity satisfactory to it against the costs, expenses and liabilities which might be incurred by it in compliance with such request or direction satisfactory to the Trustee or such Agent, as applicable;

(f) neither the Trustee nor any Agent shall be bound to make any investigation into the facts or matters stated in any resolution, certificate, statement, instrument, report, opinion, notice, request, direction, consent, order, bond, debenture, note, other evidence of indebtedness or other paper or document, but the Trustee and each Agent, in its discretion, may make such further inquiry or investigation into such facts or matters as it may see fit, and, if the Trustee or

63

an Agent shall determine to make such further inquiry or investigation, it shall be entitled to examine the books, records and premises of the Issuer and the Guarantor, personally or by agent or attorney at the sole cost of the Issuer and shall incur no liability or additional liability of any kind by reason of such inquiry or investigation;

(g) the Trustee and each Agent may execute any of the trusts or powers hereunder or perform any duties hereunder either directly or by or through agents or attorneys and the Trustee and each Agent shall not be responsible for any misconduct or negligence on the part, or for the supervision of, any agent or attorney appointed with due care by it hereunder;

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

The Trustee shall not be accountable for the use or application by the Issuer of Notes or the proceeds thereof.

64

Section 7.5. May Hold Notes.

The Trustee, any Paying Agent or Transfer Agent, any Registrar (if other than the Trustee) or any other agent of the Issuer or the Guarantors, in its individual or any other capacity, may become the owner or pledgee of Notes and, subject to Section 7.8 and 7.12, may otherwise deal with the Issuer and the Guarantors with the same rights it would have if it were not Trustee, Paying Agent, Transfer Agent, Registrar or such other agent.

Section 7.6. Money Held in Trust.

All moneys received by the Trustee or any Paying Agent shall, until used or applied as herein provided, be held in trust for the purposes for which they were received, and need not be segregated from other funds of the Trustee or Paying Agent, except as otherwise required by law. Neither the Trustee nor any Paying Agent shall be under any liability for interest on any moneys received by it hereunder except such as it may agree in writing with the Issuer to pay thereon.

Section 7.7. Compensation and Reimbursement.

The Issuer and the Guarantors agree:

(1) to, jointly and severally, pay to the Trustee and the Agents from time to time upon demand such compensation for all services rendered by it hereunder as shall be agreed upon in writing (which compensation shall not be limited by any provision of law in regard to the compensation of a trustee of an express trust), as such fees may be adjusted from time to time;

(2) except as otherwise expressly provided herein, to, jointly and severally, reimburse each of the Trustee and the Agents upon its request for all reasonable expenses and disbursements incurred or made by it in accordance with any provision of this Indenture (including the reasonable compensation and the expenses and disbursements of their agents and counsel), except any such expense, disbursement or advance as may be attributable to its gross negligence or willful misconduct; and

(3) to, jointly and severally, indemnify each the Trustee and the Agents for, and to hold each harmless against, any loss, liability, cost, damage, claim or expense (including taxes, other than taxes based on or measured by income, and the reasonable compensation, expenses and disbursements of its agents, accountants, experts and counsel) incurred without gross negligence or willful misconduct on its part as determined in a final judgment of a court with competent jurisdiction, arising out of or in connection with the acceptance or administration of this trust or the performance by it of its duties and obligations or the exercise of its rights hereunder, including the costs and expenses of enforcing this Indenture against the Issuer or the Guarantors, as the case may be (including, without limitation, this Section 7.7), and of defending against any claim (whether asserted by any Holder or the Issuer or the Guarantors or any other Person, as the case may be) or liability in connection with the exercise or performance of any of its powers or duties hereunder. The provisions of this Section 7.7 shall survive any termination of this Indenture and the resignation or removal of the Trustee, the Principal Paying Agent or other Paying Agent.

65

As security for the performance of the obligations of the Issuer or the Guarantors, as the case may be, under this Section 7.7, the Trustee shall have a lien prior to the Notes upon all property and funds held or collected by the Trustee, except funds held in trust for the payment of principal of (and premium, if any) or interest on particular Notes. The Trustee’s right to receive payment of any amounts due under this Section 7.7 shall not be subordinate to any other liability or indebtedness of the Issuer or the Guarantors, as the case may be (even though the Notes may be so subordinated).

The obligation of the Issuer under this Section 7.7 shall survive the satisfaction and discharge of this Indenture and the earlier resignation or removal or the Trustee. The indemnification provided in this Section 7.7 shall extend to the officers, directors, agents and employees of the Trustee.

When the Trustee incurs expenses or renders services after an Event of Default specified in Section 6.1 occurs, the expenses and the compensation for such services are intended to constitute expenses of administration under Title 11, U.S. Code, or any similar Federal, State or analogous foreign law for the relief of debtors.

Section 7.8. Corporate Trustee Required; Eligibility.

There shall at all times be a Trustee hereunder which shall be a Person that is eligible pursuant to the Trust Indenture Act to act as such and has a combined capital and surplus of at least U.S.$50,000,000 and its Corporate Trust Office in The City of New York, New York. If such Person publishes reports of condition at least annually, pursuant to law or to the requirements of a Federal, State, Territorial or District of Columbia supervising or examining authority, then for the purposes of this Section, the combined capital and surplus of such Person shall be deemed to be its combined capital and surplus as set forth in its most recent report of condition so published. If at any time the Trustee shall cease to be eligible in accordance with the provisions of this Section, it shall resign immediately in the manner and with the effect hereinafter specified in this Article.

Section 7.9. Resignation and Removal; Appointment of Successor.

(a) No resignation or removal of the Trustee and no appointment of a successor Trustee pursuant to this Article shall become effective until the acceptance of appointment by the successor Trustee under Section 7.10, at which time the retiring Trustee shall be fully discharged from its obligations hereunder.

(b) The Trustee and the Principal Paying Agent may resign at any time by giving written notice thereof to the Issuer. If an instrument of acceptance by a successor Trustee or Principal Paying Agent shall not have been delivered to the Trustee or Principal Paying Agent, as the case may be, within 30 days after the giving of such notice of resignation, the resigning Trustee or Principal Paying Agent may petition, at the expense of the Issuer, any court of competent jurisdiction for the appointment of a successor Trustee or Principal Paying Agent, as the case may be.

(c) The Trustee may be removed at any time by Act of the Holders of a majority in principal amount of the Outstanding Notes, delivered to the Trustee and to the Issuer. If an

66

instrument of acceptance by a successor Trustee shall not have been delivered to the Trustee within 30 days after the giving of such notice of removal, the Issuer may petition, at its expense, any court of competent jurisdiction for the appointment of a successor Trustee.

(d) The Agents (other than the Principal Paying Agent) may resign at any time by giving written notice thereof to the Issuer. The Agents may appoint a successor Agent if the Issuer does not.

(e) So long as no Event of Default has occurred and is continuing, the Issuer may remove the Trustee or any Agent and appoint a new Trustee or Agent, as applicable, provided that such Trustee meets the eligibility requirements of Section 7.8.

(f) If at any time:

(1) the Trustee shall fail to comply with Section 7.8 after written request therefor by the Issuer or by any Holder who has been a bona fide Holder of a Note for at least six months; or

(2) the Trustee shall cease to be eligible under Section 7.8 and shall fail to resign after written request therefor by the Issuer or by any such Holder; or

(3) the Trustee shall become incapable of acting or shall be adjudged a bankrupt or insolvent or a receiver of the Trustee or of its property shall be appointed or any public officer shall take charge or control of the Trustee or of its property or affairs for the purpose of rehabilitation, conservation or liquidation, then, in any such case, (i) the Issuer by a Board Resolution may remove the Trustee, or (ii) any Holder who has been a bona fide Holder of a Note for at least six months may, on behalf of himself or herself and all others similarly situated, petition any court of competent jurisdiction for the removal of the Trustee and the appointment of a successor Trustee.

(g) If the Trustee shall resign, be removed or become incapable of acting, or if a vacancy shall occur in the office of Trustee for any cause, the Issuer, by a Board Resolution, shall promptly appoint a successor Trustee. If, within one year after such resignation, removal or incapability, or the occurrence of such vacancy, a successor Trustee shall be appointed by Act of the Holders of a majority in principal amount of the Outstanding Notes delivered to the Issuer and the retiring Trustee, the successor Trustee so appointed shall, forthwith upon its acceptance of such appointment, become the successor Trustee and supersede the successor Trustee appointed by the Issuer. If no successor Trustee shall have been so appointed by the Issuer or the Holders and accepted appointment in the manner hereinafter provided, any Holder who has been a bona fide Holder of a Note for at least six months may, on behalf of himself or herself and all others similarly situated, petition any court of competent jurisdiction at the expense of the Issuer for the appointment of a successor Trustee.

(h) The Issuer shall give notice of each resignation and each removal of the Trustee and each appointment of a successor Trustee to all Holders in the manner provided in Section 1.6. Each notice shall include the name of the successor Trustee and the address of its Corporate Trust Office at the expense of the Issuer.

67

Section 7.10. Acceptance of Appointment by Successor.

Every successor Trustee appointed hereunder shall execute, acknowledge and deliver to the Issuer, the Guarantors 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 request of the Issuer or the successor Trustee, such retiring Trustee shall, upon payment of its charges, 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, if any, provided for in Section 7.7. Upon request of any such successor Trustee, the Issuer and the Guarantors shall execute any and all instruments for more fully and certainty vesting in and confirming to such successor Trustee all such rights, powers and trusts. No successor Trustee shall accept its appointment unless at the time of such acceptance such successor Trustee shall be qualified and eligible under this Article.

Section 7.11. Merger, Conversion, Consolidation or Succession to Business.

Any corporation or other entity into which the Trustee may be merged or convened or with which it may be consolidated, or any corporation or other entity resulting from any merger, conversion or consolidation to which the Trustee shall be a party, or any corporation or other entity succeeding to all or substantially all the corporate trust business of the Trustee, shall be the successor of the Trustee hereunder, provided that such corporation or other entity shall be otherwise qualified and eligible under this Article, without the execution or filing of any paper or any further act on the part of any of the parties hereto. In case any Notes shall have been authenticated, but not delivered, by the Trustee then in office, any successor by merger, conversion or consolidation to such authenticating Trustee may adopt such authentication and deliver the Notes so authenticated with the same effect as if such successor Trustee had itself authenticated such Notes.

Section 7.12. Appointment of Authenticating Agent.

The Trustee may appoint an Authenticating Agent or Agents with respect to the Notes which shall be authorized to act on behalf of the Trustee to authenticate Notes issued upon original issue and upon exchange, registration of transfer or partial redemption thereof or pursuant to Section 3.5, and Notes so authenticated shall be entitled to the benefits of this Indenture and shall be valid and obligatory for all purposes as if authenticated by the Trustee hereunder. Wherever reference is made in this Indenture to the authentication and delivery of Notes by the Trustee or the Trustee’s certificate of authentication, such reference shall be deemed to include authentication and delivery on behalf of the Trustee by an Authenticating Agent and a certificate of authentication executed on behalf of the Trustee by an Authenticating Agent. Each Authenticating Agent shall be acceptable to the Issuer and shall at all times be a corporation organized and doing business under the laws of the United States, any State thereof or the District of Columbia, authorized under such laws to act as Authenticating Agent, having a combined capital and surplus of not less than U.S.$50,000,000 and subject to supervision or examination by Federal or State authority. If such Authenticating Agent publishes reports of

68

condition at least annually, pursuant to law or to the requirements of said supervising or examining authority, then for the purposes of this Section, the combined capital and surplus of such Authenticating Agent shall be deemed to be its combined capital and surplus as set forth in its most recent report of condition so published. If at any time an Authenticating Agent shall cease to be eligible in accordance with the provisions of this Section, such Authenticating Agent shall resign immediately in the manner and with the effect specified in this Section.

Any corporation or other entity into which an Authenticating Agent may be merged or converted or with which it may be consolidated, or any corporation or other entity resulting from any merger, conversion or consolidation to which such Authenticating Agent shall be a party, or any corporation or other entity succeeding to all or substantially all the corporate agency or corporate trust business of an Authenticating Agent, shall continue to be an Authenticating Agent, provided such corporation or other entity shall be otherwise eligible under this Section, without the execution or filing of any paper or any further act on the part of the Trustee or the Authenticating Agent.

An Authenticating Agent may resign at any time by giving written notice thereof to the Trustee and to the Issuer. The Trustee may at any time terminate the agency of an

Authenticating Agent by giving written notice thereof to such Authenticating Agent and to the Issuer. Upon receiving such a notice of resignation or upon such a termination, or in case at any time such Authenticating Agent shall cease to be eligible in accordance with the provisions of this Section, the Trustee may appoint a successor Authenticating Agent which shall be acceptable to the Issuer and shall give notice of such appointment in the manner provided in Section 1.6 to all Holders of Notes. Any successor Authenticating Agent upon acceptance of its appointment hereunder shall become vested with all the rights, powers and duties of its predecessor hereunder, with like effect as if originally named as an Authenticating Agent. No successor Authenticating Agent shall be appointed unless eligible under the provisions of this Section.

The Issuer agrees to pay to each Authenticating Agent from time to time reasonable compensation for its services under this Section.

If an appointment is made pursuant to this Section, the Notes may have endorsed thereon, in lieu of the Trustee’s certificate of authentication, an alternative certificate of authentication in the following form:

“This is one of the Notes referred to in the within-mentioned Indenture.

THE BANK OF NEW YORK MELLON
as Trustee

|  |  | By: |  |
|  |  | as Authenticating Agent” |

The Issuer will furnish or cause to be furnished to the Trustee

(a) semi-annually, not more than 15 days after each Record Date, a list, in such form as the Trustee may reasonably require, of the names and addresses of the Holders as of such Record Date; and

(b) at such other times as the Trustee may request in writing, within 30 days after the receipt by the Issuer of any such request, a list of similar form and content as of a date not more than 15 days prior to the time such list is furnished;

The Trustee may destroy any list furnished to it as provided in Section 8.1 upon receipt of a new list so furnished.

(b) If a Holder (herein referred to as an “applicant”) applies in writing to the Trustee, and furnishes to the Trustee reasonable proof that each such applicant has owned a Note for a period of at least six months preceding the date of such application, and such application states that such applicant desires to communicate with other Holders with respect to their rights under this Indenture or under the Notes and is accompanied by a copy of the form of proxy or other communication which such applicant proposes to transmit, then the Trustee shall, within five Business Days after the receipt of such application, at its election, either

(1) afford such applicant access to the information preserved at the time by the Trustee in accordance with Section 8.2(a); or

(2) inform such applications as to the approximate number of Holders whose names and addresses appear in the information preserved at the time by the Trustee in accordance with Section 8.2(a), as to the approximate cost of mailing to such Holders the form of proxy or other communication, if any, specified in such application.

(c) Every Holder of Notes, by receiving and holding the same, agrees with the Issuer and the Trustee that neither the Issuer nor the Trustee nor any agent of either of them shall be held accountable by reason of the disclosure of any such information as to the names and addresses of the Holders in accordance with Section 8.2(b), regardless of the source from which

70

such information was derived, and that the Trustee shall not be held accountable by reason of mailing any material pursuant to a request made under Section 8.2(b).

Article IX
CONSOLIDATION, MERGER, CONVEYANCE, TRANSFER OR LEASE

Section 9.1. Mergers, Consolidations and Certain Sales of Assets.

So long as any of the Notes are Outstanding, neither the Issuer nor any Guarantor may, in a single transaction or a series of related transactions:

(1) unless the Issuer or such Guarantor, as applicable, is the surviving Person, consolidate with or merge into any other Person or permit any other Person to consolidate with or merge into the Issuer or such Guarantor, as applicable (other than a consolidation or merger of a Wholly Owned Subsidiary organized under the laws of Luxembourg, Brazil, Peru, the United States or any OECD country, in each case, with or into the Issuer or such Guarantor, as applicable); or

(2) directly or indirectly, transfer, sell, lease or otherwise dispose of all or substantially all of its assets (determined on a consolidated basis of the Issuer and its Subsidiaries or the relevant Guarantor and its Subsidiaries, as applicable) to any Person (other than the Issuer or a Guarantor) (provided that the creation of a Lien on or in any of its assets shall not in and of itself constitute the transfer, sale, lease or disposition of the assets subject to the Lien),

unless the following conditions, to the extent applicable, are met:

(i) in the case of a transaction in which the Issuer or a Guarantor does not survive or in which the Issuer or a Guarantor sells, leases or otherwise disposes of all or substantially all of its assets to any other Person, the successor entity to the Issuer or such Guarantor (1) shall expressly assume, by a supplemental indenture executed and delivered to the Trustee, all of the Issuer’s or such Guarantor’s obligations under this Indenture and (2) shall be organized under the laws of (x) Luxembourg, Brazil, Peru or any state or political subdivision thereof, (y) the United States or any state thereof or the District of Columbia or (z) any other country if such successor entity undertakes, in such supplemental indenture, to pay such additional amounts in respect of principal (and premium, if any) and interest as may be necessary in order that the net amounts paid pursuant to the Notes after deduction or withholding of any present or future withholding taxes, duties, assessments, levies, imposts or charges whatsoever imposed by or for the account of such country or any political subdivision or taxing authority thereof or therein shall equal the respective amounts of principal (and premium, if any) and interest specified in the Notes, subject to the same exceptions set forth under clauses (1) through (7) of Section 11.9, but replacing existing references in such clauses to the jurisdiction of incorporation of the Issuer or such Guarantor, as applicable, with references to such other country and references to the jurisdiction of incorporation of the Issuer or such

71

Guarantor, as applicable, under Section 4.1 shall automatically be deemed to be references to such other country;

(ii) if, as a result of any such transaction, property or assets of the Issuer or such Guarantor would become subject to a Lien prohibited by Section 12.10, the Issuer or such Guarantor, as applicable, or the successor entity to the Issuer or such Guarantor, as applicable, shall have secured the Notes as described thereunder; and

(iii) the Issuer or such Guarantor, as applicable, has delivered to the Trustee an Officer’s Certificate and an Opinion of Counsel, each stating that such consolidation, merger, conveyance, transfer, lease or acquisition and, if a supplemental indenture is required in connection with such transaction, such supplemental indenture complies with this covenant and that all conditions precedent provided for in this Indenture relating to such transaction have been complied with.

In the event of any transaction (other than a lease) described in and complying with the provisions of this Section 9.1 in which the Issuer or a Guarantor, as applicable, is not the surviving Person and the surviving Person assumes all the obligations of the Issuer or such Guarantor, as applicable, under this Indenture and the Notes or the Guarantee, as applicable, pursuant to a supplemental Indenture, such surviving Person shall succeed to, and be substituted for, and may exercise every right and power of, the Issuer or such Guarantor, as applicable, and the Issuer or such Guarantor, as applicable, will be discharged from its obligations under this Indenture and the Notes or the Guarantee, as applicable.

Article X
SUPPLEMENTAL INDENTURES

Without the consent of any Holders, the Issuer and the Trustee, at any time and from time to time, may enter into one or more supplemental indentures hereto in form satisfactory to the Trustee, for any of the following purposes:

Section 10.2. Supplemental Indentures with Consent of Holders.

With the consent of the Holders of not less than a majority in aggregate principal amount of the Outstanding Notes, by Act of said Holders delivered to the Issuer and the Trustee, and consistent with Section 6.13, the Issuer and the Trustee may enter into an indenture or supplemental indentures hereto for the purpose of adding any provisions to or changing in any manner or eliminating any of the provisions of this Indenture or of modifying in any manner the rights of the Holders under this Indenture; provided, however, that no such supplemental indenture shall, without the consent of the Holder of each outstanding Note affected thereby:

(1) change the Stated Maturity of the principal of, or any installment of interest on, any Note, or reduce the principal amount thereof or the rate of interest thereon or any premium payable thereon, or change the place of payment where, or the coin or currency in which, any Note or any premium or interest thereon is payable, or impair the right to institute suit for the enforcement of any such payment on or with respect to any Note on or after the Stated Maturity thereof (or, in the case of redemption, on or after the Redemption Date),

(2) reduce the percentage in principal amount of the Outstanding Notes, the consent of whose Holders is required for any such supplemental indenture, or the consent of whose Holders is required for any waiver (of compliance with certain provisions of this Indenture or certain defaults hereunder and their consequences) provided for in this Indenture;

(3) modify any of the provisions of this Section 10.2 or Section 6.12 or Section 11.9, except to increase any such percentage described in clause (2) above or to provide that certain other provisions of this Indenture cannot be modified or waived without the consent of the Holder of each Outstanding Note affected thereby;

73

(4) release any Guarantors from its obligations under its Guarantee or this Indenture, except in compliance with the terms of this Indenture.

It shall not be necessary for any Act of Holders under this Section to approve the particular form of any proposed supplemental indenture, but it shall be sufficient if such Act shall approve the substance thereof.

Section 10.3. Execution of Supplemental Indentures.

In executing, or accepting the additional trusts created by, any supplemental indenture permitted by this Article or the modifications thereby of the trusts created by this Indenture, the Trustee shall receive, and (subject to Section 7.1) shall be fully protected in conclusively relying upon, in addition to the documents required by Section 1.2, an Officer’s Certificate and Opinion of Counsel stating that the execution of such supplemental indenture is authorized or permitted by this Indenture. The Trustee may, but shall not be obligated to, enter into any such supplemental indenture which affects the trustee’s own rights, duties or immunities under this Indenture.

Section 10.4. Effect of Supplemental Indentures.

Notes authenticated and delivered after the execution of any supplemental indenture pursuant to this Article may, and shall if required by the Trustee, bear a notation in form approved by the Trustee as to any matter provided for in such supplemental indenture.

Section 10.6. Notice to Holders.

After a supplemental indenture under this Article becomes effective, the Issuer will send to the Holders affected thereby a notice briefly describing the terms of the supplement. The Issuer will send supplemental indentures to Holders upon request. Any failure of the Issuer to send such notice, or any defect therein, will not, however, in any way impair or affect the validity of any such supplemental indenture.

74

Article XI

COVENANTS

Section 11.1. Payment Under the Notes.

Each of the Issuer and the Guarantors shall duly and punctually pay all amounts owed by it, and comply with all its other obligations, under the terms of the Notes, the Guarantees and this Indenture (collectively, the “Transaction Documents”).

Section 11.2. Maintenance of Office or Agency.

The Issuer and the Guarantors will maintain in the Borough of Manhattan, The City of New York, New York, an office or agency where Notes may be presented or surrendered for payment, where Notes may be surrendered for registration of transfer or exchange and where notices and demands to or upon the Issuer or the Guarantors in respect of the Notes, the Guarantees and this Indenture may be served. Initially, this office will be at the Corporate Trust Office of the Trustee, unless the Issuer shall designate and maintain any other office or agency for one or more such purposes, and the Issuer and the Guarantors shall agree not to change the designation of such office without prior written notice to the Trustee and designation of a replacement office in the same general location. The Issuer will give prompt written notice to the Trustee of the location, and any change in the location, of such offices or agencies. If at any time the Issuer or the Guarantors shall fail to maintain any such required offices or agencies or shall fail to furnish the Trustee with the address thereof, such presentations, surrenders, notices and demands may be made or served at the Corporate Trust Office of the Trustee. The Issuer and the Guarantors hereby appoint the Trustee as their agent to receive all such presentations, surrenders, notices and demands.

The Issuer may also from time to time designate one or more other offices or agencies (in or outside the Borough of Manhattan, The City of New York, New York) where the Notes may be presented or surrendered for any or all such purposes and may from time to time rescind such designations (each, a “Transfer Agent”); provided, however, that no such designation or rescission shall in any manner relieve the Issuer of its obligation to maintain an office or agency in the Borough of Manhattan, The City of New York, New York. The Issuer has initially designated the offices of The Bank of New York Mellon to act as Transfer Agent. The Issuer will give prompt written notice to the Trustee of any such designation or rescission and of any change in the location of any such other office or agency.

Section 11.3. Money for Note Payments to Be Held in Trust.

If the Issuer shall at any time act as its own Paying Agent, it will, on or before each due date of the principal of (and premium, if any) or interest on any of the Notes, segregate and hold in trust for the benefit of the Persons entitled thereto a sum sufficient to pay the principal (and premium, if any) or interest so becoming due until such sums shall be paid to such Persons or otherwise disposed of as herein provided and will promptly notify the Trustee in writing of its action or failure so to act.

75

Whenever the Issuer shall have one or more Paying Agents, it will, prior to each due date of the principal of (and premium, if any) or interest on any Notes, deposit with the Principal Paying Agent a sum sufficient to pay the principal (and premium, if any) or interest (including Additional Amounts, if any) so becoming due, such sum to be held in trust for the benefit of the Persons entitled to such principal, premium or interest, and (unless such Paying Agent is the Trustee) the Issuer will promptly notify the Trustee in writing of its action or failure so to act.

The Issuer will cause each Paying Agent other than the Trustee and the Principal Paying Agent to execute and deliver to the Trustee an instrument in which such Paying Agent shall agree with the Trustee, subject to the provisions of this Section 11.3, that such Paying Agent will:

(1) hold all sums held by it for the payment of the principal of (and premium, if any) or interest on Notes in trust for the benefit of the Persons entitled thereto until such sums shall be paid to such Persons or otherwise disclosed of as herein provided;

(2) give the Trustee written notice of any default by the Issuer (or any other obligor upon the Notes) in the making of any payment of principal (and premium, if any) or interest;

(3) at any time during the continuance of any such default, upon the written request of the Trustee, forthwith pay to the Trustee all sums so held in trust by such Paying Agent; and

(4) acknowledge, accept and agree to comply in all respects with the provisions of this Indenture relating to the duties, rights and obligations of such Paying Agent.

The Issuer may at any time, for the purpose of obtaining the satisfaction and discharge of this Indenture or for any other purpose, pay, or by Issuer Order direct any Paying Agent to pay, to the Trustee all sums held in trust by the Issuer or such Paying Agent, such sums to be held by the Trustee upon the same trusts as those upon which such sums were held by the Issuer or such Paying Agent; and, upon such payment by any Paying Agent to the Trustee, such Paying Agent shall be released from all further liability with respect to such money.

Any money deposited with the Trustee or any Paying Agent, or then held by the Issuer, in trust for the payment of the principal of (and premium, if any) or interest on any Note and remaining unclaimed for two years after such principal (and premium, if any) or interest has become due and payable shall be paid to the Issuer on the Issuer’s Request, or (if then held by the Issuer) shall be discharged from such trust; and the Holder of such Note shall thereafter, as an unsecured general creditor, look only to the Issuer for payment thereof, and all liability of the Trustee or such Paying Agent with respect to such trust money, and all liability of the Issuer as trustee thereof, shall thereupon cease.

Section 11.4. Maintenance of Corporate Existence.

The Issuer and the Guarantors shall, and shall cause each of their respective Subsidiaries to, maintain in effect its corporate existence and all registrations necessary therefor and take all

76

actions to maintain all rights, privileges, titles to property, franchises and the like necessary or desirable in the normal conduct of its business, activities or operations provided that this covenant shall not require (i) the Issuer, the Guarantors or any of their respective Subsidiaries to maintain any such registration, right, privilege, title to property, franchise or the like or require the Issuer or the Guarantors to preserve the corporate existence of any of their respective Subsidiaries (other than a Subsidiary that is a Guarantor), if the failure to do so would not have a material adverse effect on the Issuer and its Subsidiaries taken as a whole or have a material adverse effect on the rights of the Holders or (ii) the Guarantors or the Issuer to preserve its corporate existence if it complies with the provisions of Section 9.1.

Section 11.5. Repurchases at the Option of the Holders upon Change of Control.

If a Change of Control occurs that results in a Rating Decline, each Holder will have the right to require the repurchase of all or any part (equal to U.S.$200,000 and integral multiples of U.S.$1,000 in excess thereof) of the Notes of that Holder pursuant to a Change of Control Offer by the Issuer or the Guarantors. No such purchase in part shall reduce the principal amount of the Notes held by any Holder to below U.S.$200,000. In the Change of Control Offer, the Issuer or a Guarantor will offer a “Change of Control Payment” in U.S. dollars equal to 101% of the aggregate principal amount of Notes repurchased plus accrued and unpaid interest and Additional Amounts, if any, on the Notes repurchased, to the date of purchase (subject to the right of the Holders of record on the relevant Record Date to receive interest and Additional Amounts, if any, on the relevant Interest Payment Date).

Within 30 days following any Change of Control that results in a Rating Decline the Issuer or the Guarantor will make a “Change of Control Offer” by notice to each Holder of Notes in accordance with the provision set out under Section 1.6, describing the transaction or transactions that constitute the Change of Control and offering to repurchase Notes on the date specified in the notice (the “Change of Control Payment Date”), which date will be no earlier than 30 days and no later than 60 days from the date such notice is mailed, pursuant to the procedures required by this Indenture and described in such notice.

The Issuer or the applicable Guarantor will comply, to the extent applicable, with the requirements of Section 14(e)-1 of the Exchange Act and any other applicable securities laws or regulations in connection with the repurchase of Notes pursuant to this covenant. To the extent that the provisions of any applicable securities laws or regulations conflict with provisions of this covenant, the Issuer or the applicable Guarantor will comply with the applicable securities laws and regulations and will not be deemed to have breached its obligations under this covenant by virtue of its compliance with such securities laws or regulations.

On the Change of Control Payment Date, the Issuer or the applicable Guarantor will, to the extent lawful:

(1) accept for payment all Notes or portions of Notes properly tendered pursuant to the Change of Control Offer; and

(2) procure that the Change of Control Payment is made in respect of all Notes or portions of Notes properly tendered.

77

The Paying Agents will promptly mail to each Holder who properly tendered Notes the Change of Control Payment for such Notes, and the Trustee will promptly authenticate and mail (or cause to be transferred by book entry) to each Holder a new Note equal in principal amount to any unpurchased portion of the Notes surrendered, if any; provided that each new Note will be in minimum denominations of U.S.$200,000 and integral multiples of U.S.$1,000 in excess thereof.

The provisions described above that require the Issuer or a Guarantor to make a Change of Control Offer following a Change of Control will be applicable whether or not any other provisions of this Indenture are applicable. However, a Change of Control Offer is only required to be made in the event that a Change of Control results in a Rating Decline. Consequently, if a Change of Control were to occur which does not result in a Rating Decline, none of the Issuer and the Guarantors would be required to launch a Change of Control Offer. Except as described above with respect to a Change of Control, this Indenture does not contain provisions that permit the Holders to require that the Issuer or a Guarantor repurchase or redeem the Notes in the event of a takeover, recapitalization or similar transaction.

None of the Issuer or the Guarantors will be required to make a Change of Control Offer upon a Change of Control 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, that are applicable to a Change of Control Offer made by the Issuer or a Guarantor and such third party purchases all Notes properly tendered and not withdrawn under the Change of Control Offer or (2) a notice of redemption has been given for all outstanding Notes pursuant to this Indenture as described under Section 4.2 unless and until there is a default in payment of the applicable Redemption Price.

Notwithstanding anything to the contrary contained herein and subject to applicable law, a Change of Control Offer may be made in advance of a Change of Control and conditioned upon the occurrence of such Change of Control and Rating Decline if a definitive agreement is in place for the Change of Control at the time of making of the Change of Control Offer.

In the event that the Holders of not less than 85% of the aggregate principal amount of Outstanding Notes accept a Change of Control Offer and the Issuer or a Guarantor or a third party purchases all the Notes held by such holders, the Issuer or a Guarantor will have the right, on not less than 10 nor more than 60 days’ prior notice to the Holders, given not more than 30 days following the purchase date pursuant to the Change of Control Offer, to redeem all of the Notes that remain outstanding following such purchase at the purchase price equal to that in the Change of Control Offer plus, to the extent not included in the purchase price, accrued and unpaid interest and Additional Amounts, if any, on the Notes that remain Outstanding, to, but excluding, the date of redemption.

Section 11.6. Payment of Taxes and Other Claims.

The Issuer and the Guarantors shall, and shall cause each of their respective Subsidiaries to, pay or discharge or cause to be paid or discharged before the same shall become delinquent, (i) all taxes, assessments and governmental charges levied or imposed upon the Issuer and the Guarantors or any of their respective Subsidiaries, as the case may be, and (ii) all lawful claims

78

for labor, materials and supplies which, if unpaid, might by law become a Lien upon the property of the Issuer or a Guarantor or any of their respective Subsidiaries, as the case may be; provided, however, that neither the Issuer nor any Guarantor nor any of their respective Subsidiaries shall be required to pay or discharge or cause to be paid or discharged any such tax, assessment, charge or claim whose amount, applicability or validity is being contested in good faith and, if appropriate, by appropriate legal proceedings, or where the failure to do so would not have a material adverse effect on the Issuer, the Guarantors and their Subsidiaries taken as a whole or have a material adverse effect on the rights of the Holders.

Section 11.7. Provision of Financial Information.

The Issuer has agreed that it will furnish to the Trustee and the Holders and to any prospective purchasers of such Notes, to the extent permitted by applicable law or contractual restrictions, upon their request, the information required to be delivered pursuant to Rule 144A(d)(4) under the Securities Act; provided that the foregoing obligation will only apply to the Issuer if it ceases to be subject to and in compliance with the reporting requirements of Section 13 or 15(d) of the Exchange Act or exempt from reporting pursuant to Rule 12g3-2(b) under the Exchange Act.

Additionally, the Issuer shall provide the Trustee and the Holders, within 120 days of the end of each fiscal year and within 60 days of the end of each of the first three fiscal quarters, annual or quarterly financial statements, as applicable, in accordance with applicable GAAP and audited in the case of annual financial statements.

Notwithstanding the foregoing, if the Issuer makes available the information described above on the Issuer’s or an Affiliate’s website or on the Electronic Data Gathering, Analysis, and Retrieval (EDGAR) website of the SEC, the Issuer will be deemed to have satisfied the reporting requirement set forth in such applicable clause. It is understood that the Trustee shall have no responsibility to determine whether any information has been posted on such websites.

Delivery of such reports, information and documents to the Trustee is for informational purposes only and the Trustee’s receipt of such reports shall not constitute constructive notice of any information contained therein or determinable from information contained therein, including the Issuer’s compliance with any of its covenants hereunder (as to which the Trustee is entitled to rely exclusively on an Officer’s Certificate or notice). The Trustee shall have no obligation to determine if and when the Issuer’s statements or reports are publicly available and accessible electronically.

Section 11.8. Statement by Officers as to Default.

(a) The Issuer will be required to furnish to the Trustee together with the delivery (or the posting on the Issuer’s or an Affiliate’s website) of its annual financial statements and in any event within 120 days after the end of each such fiscal period, an Officer’s Certificate stating whether or not to the best knowledge of the signer thereof none of the Issuer or any Guarantor is in default in the performance and observance of any of the terms, provisions and conditions of this Indenture and if the Issuer or any Guarantor is in default, specifying all such defaults and the nature and status thereof of which they may have knowledge.

Section 11.9. Payment of Additional Amounts.

Any and all payments to a Holder of principal (and premium, if any) and interest in respect of the Notes will be made free and clear of, and without withholding or deduction for, any and all present and future withholding taxes, duties, assessments, levies, imposts or charges (“Taxes”) whatsoever imposed by or on behalf of, Luxembourg, Brazil, Peru or any political subdivision or taxing authority thereof or therein or any other jurisdiction from or through which payment on the Notes is made, unless such withholding or deduction is required by law. In that event, the Issuer or a Guarantor, as the case may be, shall pay such additional amounts (the “Additional Amounts”) as will result in the receipt by the Holders of such amounts as would have been received by them if no such withholding or deduction had been required, except that no such Additional Amounts shall be payable in respect of any Note:

(1) held by, or by a third party on behalf of, a Holder or beneficial owner which is liable for such taxes, duties, assessments, levies, imposts or charges in respect of such Note by reason of its (or a fiduciary, settlor, member, shareholder or beneficiary of, or possessor of a power over, such Holder, if such Holder is an estate, trust, partnership or corporation) having some present or former connection with Luxembourg, Brazil or Peru (including being or having been a citizen or resident of Luxembourg, Brazil or Peru or being or having been engaged in trade or business therein) other than the mere holding of such Note or the enforcement of rights in respect of such Note; or

(2) where (in the case of a payment of principal, premium, if any, or interest on the Maturity Date or date of earlier redemption) the relevant Note is surrendered for payment more than 30 days after the Relevant Date except to the extent that the relevant Holder would have been entitled to such Additional Amounts if it had surrendered the relevant Note on the last day of such period of 30 days; or

(3) if such tax is an estate, inheritance, gift, sales, transfer or personal property tax or any similar tax, assessment, levy, impost or charge; or

(4) if such tax, duty, assessment, levy, impost or charge is (a) payable other than by withholding or deduction from a payment on such Note, or (b) required to be withheld or deducted by a Paying Agent and such Holder of a Note would have been able to avoid such withholding or deduction by presenting the relevant Note to another Paying Agent; or

(5) if such tax, duty, assessment, levy, impost or charge would not have been imposed but for the failure of a Holder or beneficial owner of the Note to comply with applicable certification, information, documentation or other reporting requirements

80

concerning the nationality, residence, identity or connection with Luxembourg, Brazil or Peru of such Holder or beneficial owner if (i) such compliance is required as a precondition to relief or exemption from withholding or deduction of all or part of such tax, duty, assessment, levy, impost or charge and (ii) at least 30 days prior to the date on which the Issuer or a Guarantor, as the case may be, applies this clause (5), it will have notified such Holder or beneficial owner that it will be required to comply with such requirement;

(6) if such tax, duty, assessment, levy, impost or charge is payable pursuant to the Luxembourg law dated December 23, 2005, as amended, introducing a domestic withholding tax on interest income for Luxembourg resident individuals (Relibi law); or

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

(8) in the case of any combination of items (1) through (7).

“Relevant Date” means whichever is the later of (a) the date on which the payment in question first becomes due and (b) if the full amount payable has not been received by the Paying Agent on or prior to such due date, the date on which (the full amount having been so received) notice to that effect has been given to the Holders.

Notwithstanding anything to the contrary above, none of the Issuer, a Guarantor, any Paying Agent or any other Person shall be required to pay any Additional Amounts with respect to any withholding or deduction imposed on or in respect of any Note pursuant to FATCA, any treaty, law, regulation or other official guidance enacted by any jurisdiction implementing FATCA, or any agreement between the Issuer and the United States or any authority thereof implementing FATCA.

The Issuer or the relevant Guarantor, as applicable, shall pay any present or future stamp, court or documentary taxes, or any other excise or property taxes, charges or similar levies which arise in any jurisdiction from the execution, delivery or registration of the Notes, this Indenture or any other document or instrument referred to therein, excluding any such taxes, charges or similar levies imposed by any jurisdiction outside of Luxembourg, Brazil or Peru, as applicable, except those resulting from, or required to be paid in connection with, (i) the execution in or bringing to such jurisdiction of the Notes or any document or instrument; (ii) the production before a court of such jurisdiction of the Notes or any document or instrument or (iii) the enforcement of the Notes or any other such document or instrument following the occurrence of any Event of Default with respect to the Notes.

References to principal, premium, if any, or interest in this Indenture or the Notes shall be deemed to include any Additional Amounts in respect of principal, premium, if any, or interest (as the case may be) which may be payable under the Notes.

81

If the Issuer or a Guarantor becomes subject at any time to any taxing jurisdiction other than Luxembourg, Brazil or Peru, references herein to Luxembourg, Brazil or Peru, as applicable, shall be construed to include such other jurisdiction.

The Trustee shall have no obligation to determine whether any Additional Amounts are owed or for the calculation thereof.

87

Section 12.6. Reinstatement.

If the Defeasance Trustee or the Paying Agent is unable to apply any money in accordance with Section 12.2 or 12.3 by reason of any order or judgment of any court or governmental authority enjoining, restraining or otherwise prohibiting such application, then the obligations of the Issuer and the Guarantors under this Indenture, the Guarantees and the Notes, if any, shall be revived and reinstated as though no deposit had occurred pursuant to this Article until such time as the Defeasance Trustee or Paying Agent is permitted to apply all such money in accordance with Section 12.2 or 12.3; provided, however, that if the Issuer or the Guarantors makes any payment of principal of (and premium, if any) any Note following the reinstatement of such obligations, the Issuer or the Guarantors shall be subrogated to the rights of the Holders of such Notes to receive such payment from the money held by the Defeasance Trustee or the Paying Agent.

In case of the failure of the Issuer punctually to make any such payment, each of the Guarantors hereby agrees to cause such payment to be made punctually when and as the same shall become due and payable, whether at the Stated Maturity or by acceleration, call for redemption, purchase or otherwise, and as if such payment were made by the Issuer.

The Guarantees constitute unconditional and unsubordinated obligations of each of the Guarantors that will at all times rank at least equally with all other present and future unsecured senior obligations of each such Guarantor, except for any obligations that may be preferred by provisions of law that are both mandatory and of general application.

Each of the Guarantors hereby agrees that its obligations hereunder shall be unconditional, irrespective of the validity, regularity or enforceability of any Note or this Indenture, the absence of any action to enforce the same, any release or amendment or waiver of any term of any other guarantee of, or any consent to depart from any requirement of any other guarantee, of all or any of the Notes, any waiver or consent by the Holder of any Note or by the Trustee with respect to any provisions thereof or of this Indenture, the obtaining of any judgment against the Issuer or any action to enforce the same or any other circumstances which might otherwise constitute a legal or equitable discharge or defense of a guarantor. Each of the Guarantors hereby waives notice of the acceptance of its Guarantee and of any of the obligations under this Indenture or the Notes (the “Obligations”) or of the accrual thereof, and further waives presentment, protest, notice or demand. This is a continuing guarantee and is a guarantee of payment and not of collection, and each of the Guarantors waives any right to require the Holders to initiate collection proceeds or otherwise enforce payment of the Obligations or any security or other guarantee therefor before obtaining payment hereunder.

The Guarantees shall continue to be in effect or be reinstated, as the case may be, if at any time (i) any payment in respect of any of the Obligations is rescinded or must otherwise be returned by the Holders, whether by reason of the insolvency, bankruptcy, receivership, reorganization or liquidation of the Issuer or any Guarantor or any other obligor or otherwise, all as though such payment had not been made or (ii) a Substituted Issuer, as defined in Section 13.1, assumes the Issuer’s obligations under the Notes pursuant to Article XIII hereof.

Each of the Guarantors hereby waives the benefits of diligence, presentment, demand of payment, any requirement that the Trustee or any of the Holders protect, secure, perfect or insure any security interest in or other Lien on any property subject thereto or exhaust any right or take any action against the Issuer or any other Person or any collateral, filing of claims with a court in the event of insolvency or bankruptcy of the Issuer, any right to require a proceeding first against the Issuer, protest or notice with respect to any Note or the indebtedness evidenced thereby and all demands whatsoever, and covenants, that these Guarantees will be discharged in respect of

91

any Note except by complete performance of the obligations contained in such Note and in the Guarantees. Each of the Guarantors hereby agrees that, in the event of a default in payment of principal (or premium, if any) or interest on any Note, whether at its Stated Maturity or by acceleration, redemption, purchase or otherwise, legal proceedings may be instituted by the Trustee on behalf of, or by, the Holder of such Note, subject to the terms and conditions set forth in this indenture, directly against any or all of the Guarantors to enforce the Guarantees without first proceeding against the Issuer. Each of the Guarantors agrees that if, after the occurrence and during the continuance of an Event of Default, the Trustee or any of the Holders are prevented by applicable law from exercising their respective rights to accelerate the maturity of the Notes, to collect interest on the Notes or to enforce or exercise any other right or remedy with respect to the Notes, or the Trustee or the Holders are prevented from taking any action to realize on any collateral, each of the Guarantor agrees to pay to the Trustee for the account of the Holders, upon demand therefor, the amount that would otherwise have been due and payable had such rights and remedies been permitted to be exercised by the Trustee or any of the Holders.

No provision of the Guarantees, Notes or of this Indenture shall alter or impair the Guarantees of the Guarantors, of which the Guarantees are absolute and unconditional, of the due and punctual payment of the principal (and premium, if any) and interest (and Additional Amounts, if any) on the Note and the obligation under this Indenture upon which each Guarantee is endorsed.

Each of the Guarantors shall be subrogated to all rights of the Holders of the Notes upon which its Guarantee is endorsed against the Issuer in respect of any amounts paid by each of the Guarantors on account of such Note pursuant to the provisions of the Guarantees or this Indenture; provided, however, that none of the Guarantors shall be entitled to enforce or to receive any payments arising out of, or based upon, such right of subrogation until the principal of (and premium, if any) and interest (and Additional Amounts, if any) on all Notes issued hereunder shall have been paid in full.

The Guarantees shall remain in full force and effect and continue to be effective should any petition be filed by or against the Issuer for liquidation or reorganization, should the Issuer become insolvent or make an assignment for the benefit of creditors or should a receiver or trustee be appointed for all or any significant part of the Issuer’s assets, and shall, to the fullest extent permitted by law, continue to be effective or be reinstated, as the case may be, if at any time payment and performance of the obligations under the Notes is, pursuant to applicable law, rescinded or reduced in amount, or must otherwise be restored or returned by any obligee on the Notes, whether as a “voidable preference,” “fraudulent transfer” or otherwise, all as though such payment or performance had not been made. In the event that any payment, or any part thereof, is rescinded, reduced, restored or returned, the Notes shall, to the fullest extent permitted by law, be reinstated and deemed reduced only by such amount paid and not so rescinded, reduced, restored or returned.

Each of the Guarantors hereby irrevocably waives all benefits set forth in the following provisions of the Brazilian law: articles 333, sole paragraph, 366, 368, 827, 829, sole paragraph, 830, 834, 835, 837 and 838 of the Brazilian Civil Code and articles 130 and 794 of the Brazilian Civil Procedure Code.

92

No stockholder, officer, director, employer or incorporator, past, present or future, of any Guarantor, as such, shall have any personal liability under the Guarantee by reason of his, her or its status as such stockholder, officer, director, employer or incorporator.

Section 14.2. Delivery of the Guarantee.

The delivery of any Note by the Trustee, after the authentication thereof hereunder, shall constitute due delivery of the Guarantees set forth herein on behalf of the Guarantors.

Section 14.3. Release of Guarantor.

(a) Concurrently with any consolidation or merger of any of the Guarantors or any sale or conveyance of the property of any of the Guarantors as an entirety or substantially as an entirety, in each case as permitted by Section 9.1(a) hereof, and upon delivery by such Guarantor to the Trustee of an Officer’s Certificate and an Opinion of Counsel to the effect that such consolidation, merger, sale or conveyance was made in accordance with Section 9.1(a) hereof, the Trustee shall execute any documents reasonably required in order to evidence the release of such Guarantor from its obligations under its Guarantee endorsed on the Notes and under this Article XIV.

(b) Concurrently with the defeasance of the Notes under Section 12.2 hereof or the covenant defeasance of the Notes under Section 12.3 hereof, each of the Guarantors shall be released from all of its obligations under its Guarantee endorsed on the Notes and under this Article XIV.

Article XV

MEETINGS OF HOLDERS OF SECURITIES

Section 15.1. Purposes for Which Meetings May Be Called.

A meeting of Holders of Notes may be called at any time and from time to time pursuant to this Article to consider any matter affecting their interests, including, if proposed by the Issuer, the modification of the terms and conditions of the Notes; provided that any modification postponing the date for payment of any interest, reducing or canceling any amount of principal or the rate of interest payable or altering the currency of payment in respect of the Notes will only be binding if passed at a meeting of Holders at which a special quorum (as set forth in Section 15.4) is present.

Section 15.2. Call, Notice and Place of Meetings.

(1) The Trustee may at any time call a meeting of Holders of Notes of any series for any purpose specified in Section 15.1, to be held at such time and at such place in the Borough of Manhattan, The City of New York as the Trustee shall determine. Notice of every meeting of Holders of Notes, setting forth the time and the place of such meeting and in general terms the action proposed to be taken at such meeting, shall be given, in the manner provided in Section 1.6, not less than 21 nor more than 180 days prior to the date fixed for the meeting.

93

(2) In case at any time the Issuer, pursuant to a Board Resolution, or the Holders of at least 10% in principal amount of the Outstanding Notes shall have requested the Trustee to call a meeting of the Holders of Notes for any purpose specified in Section 15.1, by written request setting forth in reasonable detail the action proposed to be taken at the meeting, and the Trustee shall not have made the first publication of the notice of such meeting within 21 days after receipt of such request or shall not thereafter proceed to cause the meeting to be held as provided herein, then the Issuer or the Holders of Notes in the amount specified above, as the case may be, may determine the time and the place in the Borough of Manhattan, The City of New York for such meeting and may call such meeting for such purposes by giving notice thereof as provided in subsection (1) of this Section.

Section 15.3. Persons Entitled to Vote at Meetings.

To be entitled to vote at any meeting of Holders of Notes, a Person shall be (i) a Holder on a Record Date established pursuant to Section 15.5 of one or more Outstanding Notes, or (ii) a Person appointed by an instrument in writing as proxy for a Holder or Holders of one or more Outstanding Notes by such Holder or Holders. The only Persons who shall be permitted to be present or to speak at any meeting of Holders of Notes of any series shall be the Persons entitled to vote at such meeting and their counsel, any representatives of the Trustee and its counsel and any representatives of the Issuer and its counsel.

Section 15.4. Quorum; Action.

The Persons entitled to vote a majority in principal amount of the Outstanding Notes shall constitute a “quorum” for a meeting of Holders of Notes, however, any modification postponing the date for payment of any interest, reducing or canceling any amount of principal or the rate of interest payable or altering the currency of payment in respect of the Notes will only be binding if passed at a meeting of Holders of at least 66 ⅔% of the Notes (a “special quorum”). In the absence of a quorum or a special quorum, as the case may be, within 15 minutes (or such longer period not exceeding 30 minutes as the chairman may decide) of the time appointed for any such meeting, the meeting shall if convened upon the requisition of Holders be dissolved. In any other case it shall stand adjourned to the same day in the next week (or if such day is not a Business Day the next succeeding Business Day) at the same time and place. If within 15 minutes (or such longer period not exceeding 30 minutes as the chairman may decide) after the time appointed for any adjourned meeting a quorum or a special quorum, as the case may be, is not present for the transaction of any particular business, then, subject and without prejudice to the transaction of the business (if any) for which a quorum or a special quorum, as the case may be, is present, the chairman may either (with the approval of the Trustee) dissolve such meeting or adjourn the same for such period, being not less than ten calendar days (but without any maximum number of calendar days), and to such place as may be appointed by the chairman either at or subsequent to such adjourned meeting and approved by the Trustee, and the provisions of this sentence shall apply to all further adjourned such meetings.

Notice of the reconvening of any adjourned meeting shall be given as provided in Section 15.2(1), except that such notice need be given only once not less than five days prior to the date on which the meeting is scheduled to be reconvened. Notice of a reconvening of an adjourned

94

meeting shall state expressly the percentage, as provided above, of the principal amount of the Outstanding Notes of such series which shall constitute a quorum.

Any resolution passed or decision taken at any meeting of Holders of Notes of any series duly held in accordance with this Section shall be binding on all the Holders of Notes of such series, whether or not presented or represented at the meeting. However, for the avoidance of doubt, no actions taken at such meeting shall be binding on all Holders of Notes unless such actions were approved by the minimum percentage in principal amount of the Outstanding Notes of the series as required elsewhere in this Indenture with respect to such actions.

Section 15.5. Determination of Voting Rights; Conduct and Adjournment of Meetings.

(a) Notwithstanding any other provisions of this Indenture, the Trustee may make such reasonable regulations as it may deem advisable for any meeting of Holders of Notes of a series in regard to proof of the holding of Notes of such series and the appointment of proxies and in regard to the appointment and duties of inspectors of votes, the submission and examination of proxies, certificates and other evidence of the right to vote, and such other matters concerning the conduct of the meeting as it shall deem appropriate. Except as otherwise permitted or required by any such regulations, the holding of Notes shall be proved in the manner specified in Section 1.4 and the appointment of any proxy shall be proved in the manner specified in Section 1.4. Such regulations may provide that written instruments appointing proxies, regular on their face, may be presumed valid and genuine without the proof specified in Section 1.4 or other proof.

(b) The Trustee shall, by an instrument in writing, appoint a temporary chairman of the meeting, unless the meeting shall have been called by the Issuer or by Holders of Notes as provided in Section 15.2(2), in which case the Issuer or the Holders of Notes of the series calling the meeting, as the case may be, shall in like manner appoint a temporary chairman. A permanent chairman and a permanent secretary of the meeting shall be elected by vote of the Persons entitled to vote a majority in principal amount of the Outstanding Notes of such series represented at the meeting.

(c) At any meeting each Holder of a Note of such series or proxy shall be entitled to one vote for each $1,000 principal amount of the Outstanding Notes of such series held or represented by him or her; provided, however, that no vote shall be cast or counted at any meeting in respect of any Note challenged as not Outstanding and ruled by the chairman of the meeting to be not Outstanding. The chairman of the meeting shall have no right to vote, except as a Holder of a Note of such series or proxy.

(d) Any meeting of Holders of Notes of any series duly called pursuant to Section 15.2 at which a quorum is present may be adjourned from time to time by Persons entitled to vote a majority in principal amount of the Outstanding Notes of such series represented at the meeting, and the meeting may be held as so adjourned without further notice.

Section 15.6. Counting Votes and Recording Action of Meetings.

The vote upon any resolution submitted to any meeting of Holders of Notes of any series shall be by written ballots on which shall be subscribed the signatures of the Holders of Notes of

95

such series or of their representatives by proxy and the principal amounts and serial numbers of the Outstanding Notes of such series held or represented by them. The permanent chairman of the meeting shall appoint two inspectors of votes who shall count all votes cast at the meeting for or against any resolution and who shall make and file with the secretary of the meeting their verified written reports in duplicate of all votes cast at the meeting. A record, at least in duplicate, of the proceedings of each meeting of Holders of Notes of any series shall be prepared by the secretary of the meeting and there shall be attached to said record the original reports of the inspectors of votes on any vote by ballot taken thereat and affidavits by one or more persons having knowledge of the facts setting forth a copy of the notice of the meeting and showing that said notice was given as provided in Section 15.2 and, if applicable, Section 15.5. Each copy shall be signed and verified by the affidavits of the permanent chairman and secretary of the meeting and one such copy shall be delivered to the Issuer, and another to the Trustee to be preserved by the Trustee, the latter to have attached thereto the ballots voted at the meeting. Any record so signed and verified shall be conclusive evidence of the matters therein stated.

In connection with such request, and in respect of such Notes, the Transferor does hereby certify that such transfer has been effected in accordance with the transfer restrictions set forth in the Notes and that:

(A) The offer of the Notes was not made to a person in the United States; and

(B) either:
