Such instrument or instruments (and the action embodied therein and evidenced thereby) are herein sometimes referred to as the “Act” of the Holders signing such instrument or instruments. Proof of execution of any such instrument or of a writing appointing any such agent shall be sufficient for any purpose of this Indenture and (subject to Section 601) conclusive in favor of the Trustee and the Company, if made in the manner provided in this Section 104.

(b)    The fact and date of the execution by any Person of any such instrument or writing may be proved by the affidavit of a witness of such execution or by a certificate of a notary public or other officer authorized by law to take acknowledgments of deeds, certifying that the individual signing such instrument or writing acknowledged to him the execution thereof. Where such execution is by a signer acting in a capacity other than his individual capacity, such certificate or affidavit shall also constitute sufficient proof of his authority.

If any record date is set pursuant to this paragraph, the Holders of Outstanding Securities of the relevant series 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 Securities of such series on such record date. Nothing in this paragraph shall be construed to prevent the Company 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

11

previously set shall automatically and with no action by any Person be canceled 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 Securities of the relevant series on the date such action is taken. Promptly after any record date is set pursuant to this paragraph, the Company, 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 Securities of the relevant series in the manner set forth in Section 106.

(f)    The Trustee may set any day as a record date for the purpose of determining the Holders of Outstanding Securities of any series entitled to join in the giving or making of (i) any Notice of Default, (ii) any declaration of acceleration referred to in Section 502, (iii) any request to institute proceedings referred to in Section 507(2) or (iv) any direction referred to in Section 512, in each case with respect to Securities of such series. If any record date is set pursuant to this paragraph, the Holders of Outstanding Securities of such series on such record date, and no other Holders, shall be entitled to join in such notice, declaration, request or direction, 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 Securities of such series on such record date. Nothing in this paragraph shall be construed to prevent the Trustee from setting a new record date for any action (whereupon the record date previously set shall automatically and without any action by any Person be canceled and of no effect), nor shall anything in this paragraph be construed to render ineffective any action taken by Holders of the requisite principal amount of Outstanding Securities of the relevant series on the date such action is taken. Promptly after any record date is set pursuant to this paragraph, the Trustee, at the Company’s expense, shall cause notice of such record date, the proposed action by Holders and the applicable Expiration Date to be given to the Company in writing and to each Holder of Securities of the relevant series in the manner set forth in Section 106.

(g)    With respect to any record date set pursuant to this Section 104, the party hereto that sets such record date may designate any day as the “Expiration Date” and from time to time may change the Expiration Date to any earlier or later day; provided that no such change shall be effective unless notice of the proposed new Expiration Date is given to the other party hereto in writing, and to each Holder of Securities of the relevant series in the manner set forth in Section 106, 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 104, the party hereto that 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.

12

Without limiting the foregoing, a Holder entitled hereunder to take any action hereunder with regard to any particular Security may do so with regard to all or any part of the principal amount of such Security 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.

SECTION 105.     Notices, Etc., to Trustee, Paying Agent and Company .

Any request, demand, authorization, direction, notice, consent, waiver or Act of Holders or other document provided or permitted by this Indenture to be made upon, given or furnished to, or filed with:

(1)    the Trustee or the Paying Agent by any Holder or by the Company shall be sufficient for every purpose hereunder if made, given, furnished or filed in writing (which may be by facsimile) to or with the Trustee or the Paying Agent at its Corporate Trust Office, or

(2)    the Company by the Trustee, the Paying Agent or by any Holder shall be sufficient for every purpose hereunder (unless otherwise herein expressly provided) if in writing and mailed, first-class postage prepaid, to the Company addressed to it at the address of its principal office specified in the first paragraph of this instrument, Attention: Chief Financial Officer, or at any other address previously furnished in writing to the Trustee by the Company.

The Trustee may rely upon and comply with instructions or directions sent by any Holder or by the Company via unsecured facsimile or email transmission and the Trustee shall not be liable for any loss, liability or expense of any kind incurred by the Company or any Holder due to the Trustee’s reliance upon and compliance with such instructions or directions; provided , however , that such losses, liabilities or expenses have not arisen from the negligence or willful misconduct of the Trustee, it being understood that the failure of the Trustee to verify or confirm that the person providing the instructions or directions, is, in fact, an authorized representative of the Holder or the Company does not constitute negligence or willful misconduct.

SECTION 106.     Notice to Holders; Waiver .

Notices to Holders of any securities that are not in the form of a Global Security shall be mailed to them by first-class by the Company or, at the Company’s request, by the Trustee. Notices to the Holders of any Securities that are not in the form of a Global Security shall be given to the Depositary in accordance with the Applicable Procedures.

Notices shall be deemed to have been given on the date of delivery to the depositary or mailing, as applicable.

Any notice or communication mailed to a Holder of any Securities that are not in the form of a Global Security shall be mailed to such Holder’s address as it appears on the Register and shall be sufficiently given if so mailed within the time prescribed.

13

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

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

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.

SECTION 107.     Conflict with Trust Indenture Act .

Subsequent to the qualification of this Indenture under the Trust Indenture Act, if any provision hereof limits, qualifies or conflicts with a provision of the Trust Indenture Act that is required under such Act to be a part of and govern this Indenture, the latter provision shall control. Subsequent to the qualification of this Indenture under the Trust Indenture Act, if any provision of this Indenture modifies or excludes any provision of the Trust Indenture Act that may be so modified or excluded, the latter provision shall be deemed to apply to this Indenture as so modified or to be excluded, as the case may be.

SECTION 108.     Effect of Headings and Table of Contents .

The Article and Section headings herein and the Table of Contents are for convenience only and shall not affect the construction hereof.

SECTION 203.     Form of Reverse of Security .

This Security is one of a duly authorized issue of securities of the Company (the “Securities”), issued and to be issued in one or more series under an Indenture, dated as of October 1, 2018 (the “Indenture”), among the Company, Citibank, N.A., as Trustee (the “Trustee,” which term includes any successor trustee under the Indenture), Registrar and Transfer Agent, and Citibank, N.A., London Branch, as Paying Agent, and reference is hereby made to the Indenture for a statement of the respective rights, limitations of rights, duties and immunities thereunder of the Company, the Trustee and the Holders of the Securities and of the terms upon which the Securities are, and are to be, authenticated and delivered. The terms, conditions and provisions of this Security are those stated in the Indenture (including those made a part of the Indenture by reference to the Trust Indenture Act). This Security is one of the series designated on the face hereof.

Additional securities on terms and conditions identical to those of this Security (except for issue date, issue price and the date from which interest shall accrue and, if applicable, first be paid) may be issued by the Company without the consent of the Holders of the Securities. The amount evidenced by such additional securities shall increase the aggregate principal amount of, and shall be consolidated and form a single series with, the Securities, in which case the Schedule of Increases and Decreases in Global Security attached hereto will be correspondingly adjusted.

In any case where any Interest Payment Date, Redemption Date or Stated Maturity of any Security shall not be a Business Day, then (notwithstanding any other provision of the Indenture or of the Securities) payment of principal and premium, if any, or interest need not be made on such date, but may be made on the next succeeding Business Day with the same force and effect as if made on the Interest Payment Date, Redemption Date or at the Stated Maturity, as the case may be; provided that no interest shall accrue for the period from and after such Interest Payment Date, Redemption Date or Stated Maturity, as the case may be.

[ If applicable, insert  — The Securities of this series are subject to redemption upon not less than ……days’ nor more than ……days’ notice, at any time [ if applicable, insert  — on or after ……, 20…], as a whole or in part, at the election of the Company, at the following Redemption Prices (expressed as percentages of the principal amount): If redeemed [ if applicable, insert  — on or before ……,…%, and if redeemed] during the 12-month period beginning …… ……of the years indicated,

20

and thereafter at a Redemption Price equal to …… % of the principal amount, together in the case of any such redemption with accrued interest to the Redemption Date, but interest installments whose Stated Maturity is on or prior to such Redemption Date shall be payable to the Holders of such Securities or one or more Predecessor Securities, of record at the close of business on the relevant Record Dates referred to on the face hereof, all as provided in the Indenture. ]

[ If the Security is subject to redemption of any kind, insert  — In the event of redemption of this Security in part only, a new Security or Securities of this series and of like tenor for the unredeemed portion hereof shall be issued in the name of the Holder hereof upon the cancellation hereof. ]

[ If the Security is not an Original Issue Discount Security, insert  — If an Event of Default with respect to Securities of this series shall occur and be continuing, the principal of all of the Securities of this series may be declared due and payable in the manner and with the effect provided in the Indenture. ]

[ If the Security is an Original Issue Discount Security, insert  — If an Event of Default with respect to Securities of this series shall occur and be continuing, an amount of principal of all of the Securities of this series may be declared due and payable in the manner and with the effect provided in the Indenture. Such amount shall be equal to — insert formula for determining the amount . Upon payment (i) of the amount of principal so declared due and payable and (ii) of interest on any overdue principal, premium and interest (in each case to the extent that the payment of such interest shall be legally enforceable), all of the Company’s obligations in respect of the payment of the principal of and premium and interest, if any, on the Securities of this series shall terminate. ]

All payments of principal, premium, if any, and interest in respect of the Securities shall be made after withholding or deduction for any present or future taxes, duties, assessments or governmental charges of whatever nature imposed, levied, collected, withheld or assessed by or on behalf of Mexico or any authority therein or thereof having power to tax (“Mexican Taxes”). To the extent Mexican Taxes are required to be withheld or deducted from any such payment, the Company shall pay, as provided for in and subject to the exceptions set forth in the Indenture, such additional amounts as may be necessary to ensure that the net amount actually received by the Holder after such withholding or deduction is equal to the amount that the Holder would have received had no such withholding or deduction been required.

The Company shall pay all stamp, issue, registration, documentary or other similar duties, if any, which may be imposed by Mexico or any governmental entity or political subdivision therein or thereof, or any taxing authority of or in any of the foregoing, with respect to the Indenture or the issuance of the Securities.

21

All references herein, in the Indenture, or in one or more supplemental indentures thereto and the Securities to principal, premium, if any, interest or any other amount payable in respect of any Security shall be deemed to include all Additional Amounts, if any, payable in respect of such principal, premium, interest or other amount payable, unless the context otherwise requires, and express mention of the payment of Additional Amounts in any provision hereof or thereof shall not be construed as excluding reference to Additional Amounts in those provisions hereof where such express mention is not made.

In the event that Additional Amounts actually paid with respect to the Securities pursuant to the preceding paragraphs are based on rates of deduction or withholding of withholding taxes in excess of the appropriate rate applicable to the Holder of such Securities, and, as a result thereof such Holder is entitled to make claim for a refund or credit of such excess from the authority imposing such withholding tax, then such Holder shall, by accepting such Securities, be deemed to have assigned and transferred all right, title, and interest to any such claim for a refund or credit of such excess to the Company. However, by making such assignment, the Holder makes no representation or warranty that the Company will be entitled to receive such claim for a refund or credit and incurs no other obligation with respect thereto.

All references in the Indenture, one or more supplemental indentures thereto and the Securities to principal in respect of any Security shall be deemed to mean and include any Redemption Price payable in respect of such Security pursuant to any redemption right hereunder (and all such references to the Stated Maturity of the principal in respect of any Security shall be deemed to mean and include the Redemption Date with respect to any such Redemption Price), and all such references to principal, premium, interest or Additional Amounts shall be deemed to mean and include any amount payable in respect hereof pursuant to Section 1009 of the Indenture.

The Company may, at its option, redeem the Securities upon not less than 30 nor more than 60 days’ notice, at any time, in whole but not in part, at a Redemption Price equal to the sum of (A) 100% of the principal amount of the Securities being redeemed, (B) any accrued and unpaid interest thereon to the Redemption Date, (C) any premium applicable in the case of redemption prior to Maturity and (D) any Additional Amounts which would otherwise be payable thereon up to but not including the Redemption Date, solely if, as a result of any amendment to, or change in, the laws (or any rules or regulations thereunder) of Mexico or any political subdivision or taxing authority thereof or therein affecting taxation or any amendment to or change in an official interpretation or application of such laws, rules or regulations, which amendment to or change in such laws, rules or regulations becomes effective on or after …… ……, the Company would be obligated, after taking such measures as the Company may consider reasonable to avoid such requirement, to pay Additional Amounts in excess of the Additional Amounts that the Company would be obligated to pay if payments made on the Securities were subject to withholding or deduction of Mexican Taxes at the rate of 4.9%; provided, however , that (1) no notice of redemption pursuant to this paragraph may be given earlier than 90 days prior to the earliest date on which the Company would but for such redemption be obligated to pay such Additional Amounts if a payment on the Securities were then due and (2) at the time such notice of redemption is given, the Company’s obligation to pay such Additional Amounts remains in effect.

22

The Indenture permits, with certain exceptions as therein provided, the amendment thereof and the modification of the rights and obligations of the Company, on the one hand, and the rights of the Holders of the Securities of each series, on the other hand, to be affected under the Indenture at any time by the Company and the Trustee with the consent of the Holders of a majority in principal amount of the Securities at the time Outstanding of such series. The Indenture also contains provisions (i) permitting the Holders of a majority in principal amount of the Securities at the time Outstanding of each series to be affected under the Indenture, on behalf of the Holders of all Securities of such series, to waive compliance by the Company with certain provisions of the Indenture with respect to such series and (ii) permitting the Holders of a majority in principal amount of the Securities at the time Outstanding of each series to be affected under the Indenture, on behalf of the Holders of all Securities of such series, to waive certain past defaults under the Indenture and their consequences. Any such consent or waiver by the Holder of this Security shall be conclusive and binding upon such Holder and upon all future Holders of this Security and of any Security issued upon the registration of transfer hereof or in exchange hereof or in lieu hereof, whether or not notation of such consent or waiver is made upon this Security.

As provided in and subject to the provisions of the Indenture, the Holder of this Security shall not have the right to institute any proceeding with respect to the Indenture, or for the appointment of a receiver or trustee, or for any other remedy thereunder, unless such Holder shall have previously given the Trustee written notice of a continuing Event of Default with respect to the Securities of this series, the Holders of not less than 25% in principal amount of the Securities of this series at the time Outstanding shall have made written request to the Trustee to institute proceedings in respect of such Event of Default as Trustee and offered the Trustee indemnity and/or security satisfactory to it, and the Trustee shall not have received from the Holders of a majority in principal amount of Securities of this series at the time Outstanding a direction inconsistent with such request, and shall have failed to institute any such proceeding, for 60 days after receipt of such notice, request and offer of indemnity and/or security. The foregoing shall not apply to any suit instituted by the Holder of this Security for the enforcement of any payment of principal hereof or premium, if any, and/or interest hereon on or after the respective due dates expressed herein.

No reference herein to the Indenture and no provision of this Security or of the Indenture shall alter or impair the obligation of the Company, which is absolute and unconditional, to pay the principal of and premium, if any, and interest on this Security 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 (including, without limitation, the restrictions on transfer under Section 304 of the Indenture), the transfer of this Security is registrable in the Register, upon surrender of this Security for registration of transfer at the office of the Trustee or agency of the Company in any place where the principal of and any premium and interest on this

Security are payable, duly endorsed by, or accompanied by a written instrument of transfer in form satisfactory to the Company and the Registrar duly executed by, the Holder hereof or his attorney duly authorized in writing, and thereupon one or more new Securities of this series and of like tenor, of authorized denominations and for the same aggregate principal amount, shall be issued to the designated transferee or transferees.

The Securities of this series are issuable only in registered form without coupons in 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, Securities of this series are exchangeable for a like aggregate principal amount of Securities of this series of like tenor of a different authorized denomination, as requested by the Holder surrendering the same.

No service charge shall be made for any such registration of transfer or exchange, but the Company or the Trustee may require payment of a sum sufficient to cover any tax or other governmental charge payable in connection therewith.

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

[ If the Security is a Global Security, then insert — This Security is a Global Security and is subject to the provisions of the Indenture relating to Global Securities, including the limitations in Section 304 of the Indenture on transfers and exchanges of Global Securities. ]

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

Notwithstanding the provisions of Section 301 and of the preceding paragraph, if all Securities of a series are not to be originally issued at one time, it shall not be necessary to deliver the Officer’s Certificate otherwise required pursuant to Section 301 or the Company Order and Opinion of Counsel otherwise required pursuant to such preceding paragraph at or prior to the authentication of each Security of such series if such documents are delivered at or prior to the authentication upon original issuance of the first Security of such series to be issued.

Each Security shall be dated the date of its authentication.

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

SECTION 304.     Registration, Registration of Transfer and Exchange .

The Company 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 1002 being herein sometimes collectively referred to as the “Register”) in which, subject to such reasonable regulations as it may prescribe, the Company shall provide for the registration of Securities and of transfers of Securities. The Trustee is hereby appointed “Registrar” for the purpose of registering Securities and “Transfer Agent” for the purpose of transferring Securities as herein provided. Upon surrender for registration of transfer of any Security at an office or agency of the Company designated pursuant to Section 1002 for such purpose, and subject to the other provisions of this Section 304, the Company shall execute, and upon receipt of a Company Order, the Trustee shall authenticate and deliver, in the name of the designated transferee or transferees, one or more new Securities of any authorized denominations and of a like aggregate principal amount. In acting hereunder and in connection with the Securities, the Registrar and the Transfer Agent shall act solely as agents of the Company, and will not thereby assume any obligations towards or relationships of agency or trust for or with any Holder.

At the option of the Holder, and subject to the other provisions of this Section 304, Securities of any series may be exchanged for other Securities of any same series, of any authorized denominations and of a like aggregate principal amount, upon surrender

29

of the Securities to be exchanged at such office or agency. Whenever any Securities are so surrendered for exchange, and subject to the other provisions of this Section 304, the Company shall execute, and upon receipt of a Company Order, the Trustee shall authenticate and deliver, the Securities which the Holder making the exchange is entitled to receive.

All Securities issued upon any registration of transfer or exchange of Securities shall be the valid obligations of the Company, evidencing the same debt, and subject to the other provisions of this Section 304, entitled to the same benefits under this Indenture, as the Securities surrendered upon such registration of transfer or exchange.

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

No service charge shall be made for any registration of transfer or exchange of Securities, but the Company 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 Securities, other than exchanges pursuant to Section 906 or Section 1105 not involving any transfer.

If the Securities of any series (or of any series and specified tenor) are to be redeemed in part, the Company shall not be required (A) to issue, register the transfer of or exchange any Securities of that series (or of that series and specified tenor, as the case may be) during a period beginning at the opening of business 15 days before the day of the mailing of a notice of redemption of any such Securities selected for redemption under Section 1102 and ending at the close of business on the day of such mailing, or (B) to register the transfer of or exchange any Security so selected for redemption in whole or in part, except the unredeemed portion of any Security being redeemed in part.

The provisions of Clauses (1), (2), (3), (4) and (5) below shall apply only to Global Securities:

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

(2)    Notwithstanding any other provision in this Indenture or the Securities, no Global Security may be exchanged in whole or in part for Securities registered, and no transfer of a Global Security in 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 Company that it is unwilling or unable to continue as Depositary for such Global Security and a successor Depositary is not appointed within 90 days or (ii) has ceased to be a clearing

30

agency registered under the Exchange Act and a successor Depositary is not appointed within 90 days, (B) there shall have occurred and be continuing an Event of Default with respect to such Global Security or (C) a request for certificates has been made by the Company upon 60 days’ prior written notice given to the Trustee in accordance with the Depositary’s customary procedures and a copy of such notice has been received by the Company from the Trustee. Any Global Security exchanged pursuant to Clause (A) above shall be so exchanged in whole and not in part and any Global Security exchanged pursuant to Clause (B) or (C) above may be exchanged in whole or from time to time in part as directed by the Depositary. Any Security issued in exchange for a Global Security or any portion thereof shall be a Global Security; provided that any such Security so issued that is registered in the name of a Person other than the Depositary or a nominee thereof shall not be a Global Security.

(3)    Securities issued in exchange for a Global Security or any portion thereof pursuant to Clause (2) above shall be issued in definitive, fully registered form, without interest coupons, shall have an aggregate principal amount equal to that of such Global Security or portion thereof to be so exchanged, shall be registered in such names and be in such authorized denominations as the Depositary shall designate and shall bear any legends required hereunder. Any Global Security to be exchanged in whole shall be surrendered by the Depositary to the Trustee, as Registrar. With regard to any Global Security to be exchanged in part, either such Global Security shall be so surrendered for exchange or, if the Trustee is acting as custodian for the Depositary or its nominee with respect to such Global Security, the principal amount thereof shall be reduced, by an amount equal to the portion thereof to be so exchanged, by means of an appropriate adjustment made on the records of the Trustee. Upon any such surrender or adjustment and its receipt of a Company Order, the Trustee shall authenticate and deliver the Security issuable on such exchange to or upon the order of the Depositary or an authorized representative thereof.

(4)    In the event of the occurrence of any of the events specified in Clause (2) above, the Company shall promptly make available to the Trustee a reasonable supply of certificated Securities in definitive, fully registered form, without interest coupons.

(5)    Neither any members of, or participants in, the Depositary (“Agent Members”) nor any other Persons on whose behalf Agent Members may act, shall have any rights under this Indenture with respect to any Global Security, or under any Global Security, and the Depositary or such nominee, as the case may be, may be treated by the Company, the Trustee and any agent of the Company or the Trustee as the absolute owner and holder of such Global Security for all purposes whatsoever. Notwithstanding the foregoing, nothing herein shall prevent the Company, the Trustee or any agent of the Company or the Trustee from giving effect to any written certification, proxy or other authorization furnished by the Depositary or such nominee, as the case may be, or impair, as between the Depositary, its Agent Members and any other person on whose behalf an Agent Member may act, the operation of customary practices of such Persons governing the exercise of the rights of a holder of any Security.

31

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

The Trustee shall have no obligation or duty to monitor, determine or inquire as to compliance with any restrictions on transfer imposed under this Indenture or under applicable law with respect to any transfer of any interest in any Security (including any transfers between or among the Depositary participants, members or beneficial owners in any Global Security) other than to require delivery of such certificates and other documentation or evidence as are expressly required by, and to do so if and when expressly required by, the terms of this Indenture, and to examine the same to determine substantial compliance as to form with the express requirements hereof. Neither the Trustee nor any of its agents shall have any responsibility for any actions taken or not taken by the Depositary.

SECTION 305.     Mutilated, Destroyed, Lost and Stolen Securities .

If any mutilated Security is surrendered to the Trustee, the Company shall execute and upon receipt of a Company Order, the Trustee shall authenticate and deliver in exchange therefor a new Security of the same series and of like tenor and principal amount and bearing a number not contemporaneously outstanding.

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

32

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

Upon the issuance of any new Security under this Section 305, the Company may require the payment of a sum sufficient to cover any tax or other governmental charge that may be imposed in relation thereto and any other expenses (including the fees and expenses of the Trustee) connected therewith.

Every new Security of any series issued pursuant to this Section 305 in lieu of any destroyed, lost or stolen Security shall constitute an original additional contractual obligation of the Company, whether or not the destroyed, lost or stolen Security 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 Securities of that series duly issued hereunder.

The provisions of this Section 305 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 Securities.

SECTION 306.     Payment of Interest; Interest Rights Preserved .

Interest on any Security 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 Security (or one or more Predecessor Securities) is registered at the close of business on the Regular Record Date for such interest.

Any interest on any Security of any series which is payable, but is not punctually paid or duly provided for, on any Interest Payment Date (“Defaulted Interest”) shall forthwith cease to be payable to the Holder on the relevant Regular Record Date by virtue of having been such Holder, and such Defaulted Interest may be paid by the Company, at its election in each case, as provided in Clause (1) or (2) below:

(1)    The Company may elect to make payment of any Defaulted Interest to the Persons in whose names the Securities of such series (or their respective Predecessor Securities) 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 Company shall notify the Trustee in writing of the amount of Defaulted Interest proposed to be paid on each Security of such series and the date of the proposed payment, and at the same time the Company shall deposit with the Paying Agent 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 with the Paying Agent to be held 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

33

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 Company of such Special Record Date and, in the name and at the expense of the Company, 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 of Securities of such series at his address as it appears in the 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 Securities of such series (or their respective Predecessor Securities) are registered at the close of business on such Special Record Date and shall no longer be payable pursuant to the following Clause (2).

(2)    The Company may make payment of any Defaulted Interest on the Securities of any series in any other lawful manner not inconsistent with the requirements of any securities exchange on which such Securities may be listed, and upon such notice as may be required by such exchange, if, after notice given by the Company 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 306, each Security delivered under this Indenture upon registration of transfer of or in exchange for or in lieu of any other Security shall carry the rights to interest accrued and unpaid, and to accrue, which were carried by such other Security.

SECTION 307.     Persons Deemed Owners .

Prior to due presentment of a Security for registration of transfer, the Company, the Trustee and any agent of the Company or the Trustee may treat the Person in whose name such Security is registered as the owner of such Security for the purpose of receiving payment of principal of (and premium, if any) and (subject to Section 306) interest on such Security and for all other purposes whatsoever, whether or not such Security be overdue, and neither the Company, the Trustee nor any agent of the Company or the Trustee shall be affected by notice to the contrary.

SECTION 308.     Cancellation .

All Securities 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 canceled by it. The Company may at any time deliver to the Trustee for cancellation any Securities previously authenticated and delivered hereunder which the Company may have acquired in any manner whatsoever, and all Securities so delivered shall be promptly canceled by the Trustee. No Securities shall be authenticated in lieu of or in exchange for any Securities canceled as provided in this Section 308, except as expressly permitted by this Indenture. All canceled Securities held by the Trustee shall be disposed of in accordance with its customary procedures unless otherwise directed by a Company Order.

34

SECTION 309.     Computation of Interest .

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

SECTION 310.     CUSIP and ISIN Numbers .

The Company in issuing the Securities may use “CUSIP” and “ISIN” numbers (if then generally in use), and, if so, the Trustee shall use “CUSIP” and “ISIN” numbers in notices of redemption as a convenience to Holders; provided that any such notice may state that no representation is made as to the correctness of such numbers either as printed on the Securities or as contained in any notice of a redemption and that reliance may be placed only on the other identification numbers printed on the Securities, and any such redemption shall not be affected by any defect in or omission of such numbers. The Company shall promptly notify the Trustee in writing of any change in the “CUSIP” and “ISIN” numbers.

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 511.     Delay or Omission Not Waiver .

No delay or omission of the Trustee or of any Holder of any Security 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.

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

SECTION 515.     Waiver of Usury, Stay or Extension Laws .

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

The Trustee, any Authenticating Agent, any Paying Agent, any Registrar or any other agent of the Company, in its individual or any other capacity, may become the owner or pledgee of Securities and, subject to Section 608 and Section 613, may otherwise deal with the Company with the same rights it would have if it were not Trustee, Authenticating Agent, Paying Agent, Registrar or such other agent.

SECTION 606.     Money Held in Trust .

SECTION 607.     Compensation and Reimbursement .

The Company agrees

(1)    to pay to the Trustee from time to time such compensation as shall be agreed in writing between the parties for all services rendered by it hereunder (which compensation shall not be limited by any provision of law in regard to the compensation of a trustee of an express trust);

(2)    except as otherwise expressly provided herein, to reimburse the Trustee upon its request for all reasonable and documented expenses, disbursements and advances incurred or made by the Trustee in accordance with any provision of this Indenture (including the reasonable compensation and the expenses and disbursements of its agents and counsel), except any such expense, disbursement or advance as may be attributable to its negligence or willful misconduct (as determined by a court of competent jurisdiction in a final, non-appealable decision); and

To secure the Company’s obligation under this Section 607, the Trustee shall have a lien prior to the Securities upon all money or property held or collected by the Trustee in its capacity as Trustee or the Paying Agent, except for such money and property which is held in trust by the Trustee or held by the Paying Agent to pay principal (and premium, if any) or interest on particular Securities.

48

SECTION 609.     Corporate Trustee Required; Eligibility .

There shall at all times be one (and only one) Trustee hereunder with respect to the Securities of each series, which may be Trustee hereunder for Securities of one or more other series. Each Trustee shall be a Person that is eligible pursuant to the Trust Indenture Act to act as such, has a combined capital and surplus of at least U.S.$50,000,000 and has its Corporate Trust Office in the Borough of Manhattan, New York City. If any such Person publishes reports of condition at least annually, pursuant to law or to the requirements of its supervising or examining authority, then for the purposes of this Section 609 and to the extent permitted by the Trust Indenture Act, 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 with respect to the Securities of any series shall cease to be eligible in accordance with the provisions of this Section 609, it shall resign immediately in the manner and with the effect hereinafter specified in this Article Six.

SECTION 610.     Resignation and Removal; Appointment of Successor .

The Trustee may resign at any time with respect to the Securities of one or more series by giving written notice thereof to the Company. If the instrument of acceptance by a successor Trustee required by Section 611 shall not have been delivered to the Trustee

49

within 60 days after the giving of such notice of resignation, the resigning Trustee may petition any court of competent jurisdiction for the appointment of a successor Trustee with respect to the Securities of such series.

The Trustee may be removed at any time with respect to the Securities of any series by Act of the Holders of a majority in principal amount of the Outstanding Securities of such series, delivered to the Trustee and to the Company.

If at any time:

(1)    the Trustee shall fail to comply with Section 608 after written request therefor by the Company or by any Holder who has been a bona fide Holder of a Security for at least six months, or

(2)    the Trustee shall cease to be eligible under Section 609 and shall fail to resign after written request therefor by the Company 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, (A) the Company by a Board Resolution may remove the Trustee with respect to all Securities, or (B) subject to Section 514, any Holder who has been a bona fide Holder of a Security for at least six months may, on behalf of himself and all others similarly situated, petition any court of competent jurisdiction for the removal of the Trustee with respect to all Securities and the appointment of a successor Trustee or Trustees.

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, with respect to the Securities of one or more series, the Company, by a Board Resolution, shall promptly appoint a successor Trustee or Trustees with respect to the Securities of that or those series (it being understood that any such successor Trustee may be appointed with respect to the Securities of one or more or all of such series and that at any time there shall be only one Trustee with respect to the Securities of any particular series) and shall comply with the applicable requirements of Section 611. If, within one year days after such resignation, removal or incapability, or the occurrence of such vacancy, a successor Trustee with respect to the Securities of any series shall be appointed by Act of the Holders of a majority in principal amount of the Outstanding Securities of such series delivered to the Company and the retiring Trustee, the successor Trustee so appointed shall, forthwith upon its acceptance of such appointment in accordance with the applicable requirements of Section 611, become the successor Trustee with respect to the Securities of such series and to that extent supersede the successor Trustee appointed by the Company. If no successor Trustee with respect to the Securities of any series shall have been so appointed by the Company or the Holders and accepted appointment in the manner required by

50

Section 611, the Trustee or any Holder who has been a bona fide Holder of a Security of such series for at least six months may, at the expense of the Company, on behalf of himself and all others similarly situated, petition any court of competent jurisdiction for the appointment of a successor Trustee with respect to the Securities of such series.

The Company shall give notice of each resignation and each removal of the Trustee with respect to the Securities of any series and each appointment of a successor Trustee with respect to the Securities of any series to all Holders of Securities of such series in the manner provided in Section 106. Each notice shall include the name of the successor Trustee with respect to the Securities of such series and the address of its Corporate Trust Office.

SECTION 611.     Acceptance of Appointment by Successor .

In case of the appointment hereunder of a successor Trustee with respect to all Securities, every such successor Trustee so appointed shall execute, acknowledge and deliver to the Company and to the retiring Trustee an instrument accepting such appointment, and thereupon the resignation or removal of the retiring Trustee shall become effective and such successor Trustee, without any further act, deed or conveyance, shall become vested with all the rights, powers, trusts and duties of the retiring Trustee; but, on the written request of the Company 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.

In case of the appointment hereunder of a successor Trustee with respect to the Securities of one or more (but not all) series, the Company, the retiring Trustee and each successor Trustee with respect to the Securities of one or more series shall execute and deliver a supplemental indenture hereto wherein each successor Trustee shall accept such appointment and which (1) shall contain such provisions as shall be necessary or desirable to transfer and confirm to, and to vest in, each successor Trustee all the rights, powers, trusts and duties of the retiring Trustee with respect to the Securities of that or those series to which the appointment of such successor Trustee relates, (2) if the retiring Trustee is not retiring with respect to all Securities, shall contain such provisions as shall be deemed necessary or desirable to confirm that all the rights, powers, trusts and duties of the retiring Trustee with respect to the Securities of that or those series as to which the retiring Trustee is not retiring shall continue to be vested in the retiring Trustee, and (3) shall add to or change any of the provisions of this Indenture as shall be necessary to provide for or facilitate the administration of the trusts hereunder by more than one Trustee, it being understood that nothing herein or in such supplemental indenture shall constitute such Trustees co-trustees of the same trust and that each such Trustee shall be trustee of a trust or trusts hereunder separate and apart from any trust or trusts hereunder administered by any other such Trustee; and upon the execution and delivery of such supplemental indenture the resignation or removal of the retiring Trustee shall become effective to the extent provided therein and each such successor Trustee, without any further act, deed or conveyance, shall become vested with all the rights, powers, trusts

51

and duties of the retiring Trustee with respect to the Securities of that or those series to which the appointment of such successor Trustee relates; but, on request of the Company or any successor Trustee, such retiring Trustee shall duly assign, transfer and deliver to such successor Trustee all property and money held by such retiring Trustee hereunder with respect to the Securities of that or those series to which the appointment of such successor Trustee relates.

Upon request of any such successor Trustee, the Company shall execute any and all instruments for more fully and certainly vesting in and confirming to such successor Trustee all such rights, powers and trusts referred to in the first or second preceding paragraph, as the case may be.

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 Six.

Notwithstanding the replacement of the Trustee pursuant to Section 610 hereof, the Company’s obligations under Section 607 shall continue for the benefit of the retiring Trustee with respect to expenses and liabilities incurred by it for actions taken or omitted to be taken in accordance with its rights, powers and duties under this Indenture prior to such replacement.

SECTION 612.     Merger, Conversion, Consolidation or Succession to Business .

Any corporation into which the Trustee may be merged or converted or with which it may be consolidated, or any corporation resulting from any merger, conversion or consolidation to which the Trustee shall be a party, or any corporation succeeding to all or substantially all the corporate trust business of the Trustee, shall be the successor of the Trustee hereunder; provided such corporation shall be otherwise qualified and eligible under this Article Six, without the execution or filing of any paper or any further act on the part of any of the parties hereto. In case any Securities 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 Securities so authenticated with the same effect as if such successor Trustee had itself authenticated such Securities.

SECTION 613.     Preferential Collection of Claims Against Company .

If and when the Trustee shall be or become a creditor of the Company (or any other obligor upon the Securities), the Trustee shall be subject to the provisions of the Trust Indenture Act regarding the collection of claims against the Company (or any such other obligor).

SECTION 614.     Appointment of Authenticating Agent .

The Trustee may appoint an Authenticating Agent or Agents which shall be authorized to act on behalf of the Trustee to authenticate Securities issued upon original issue and upon exchange, registration of transfer or partial redemption or pursuant to

52

Section 306, and Securities 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 Securities 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 Company and shall at all times be a corporation organized and doing business under the laws of the United States of America, 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 condition at least annually, pursuant to law or to the requirements of said supervising or examining authority, then for the purposes of this Section 614, 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 614, such Authenticating Agent shall resign immediately in the manner and with the effect specified in this Section 614.

Any corporation into which an Authenticating Agent may be merged or converted or with which it may be consolidated, or any corporation resulting from any merger, conversion or consolidation to which such Authenticating Agent shall be a party, or any corporation succeeding to the corporate agency or corporate trust business of an Authenticating Agent, shall continue to be an Authenticating Agent; provided such corporation shall be otherwise eligible under this Section 614, 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 Company. 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 Company. 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 614, the Trustee may appoint a successor Authenticating Agent which shall be acceptable to the Company and shall mail written notice of such appointment by first-class mail, postage prepaid, to all Holders as their names and addresses appear in the Register. 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 614.

The Company agrees to pay to each Authenticating Agent from time to time reasonable compensation for its services under this Section 614.

53

If an appointment is made pursuant to this Section 614, the Securities may have annexed thereto or endorsed thereon, in addition to the Trustee’s certificate of authentication, an alternative certificate of authentication in the following form:

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

Any application by the Trustee for written instructions from the Company 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 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 five Business Days after the date any officer of the Company 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 an omission), the Trustee shall have received written instructions in response to such application specifying the action to be taken or omitted.

Whenever the Company shall have one or more Paying Agents for any series of Securities, it shall, one business day prior to each due date of the principal of or any premium or interest on any Securities of that series, deposit with a Paying Agent a sum sufficient to pay such amount, such sum to be held as provided by the Trust Indenture Act, and (unless such Paying Agent is the Trustee) the Company shall promptly notify the Trustee of its action or failure so to act.

The Company shall cause each Paying Agent for any series of Securities other than the Trustee 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 1003, that such Paying Agent shall (1) comply with the provisions of the Trust Indenture Act applicable to it as a Paying Agent and (2) during the continuance of any default by the

The Company may at any time, for the purpose of obtaining the satisfaction and discharge of this Indenture or for any other purpose, pay, or by Company Order direct any Paying Agent to pay, to the Trustee all sums (i) held in trust by the Company, or (ii) held by such Paying Agent, such sums to be held by the Trustee in trust; 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 in trust or any Paying Agent, or then held by the Company in trust, for the payment of the principal of or any premium or interest on any Security of any series and remaining unclaimed for two years after such principal, premium or interest has become due and payable shall be paid to the Company on Company Request, or (if then held by the Company) shall be discharged from such trust; and the Holder of such Security shall thereafter, as an unsecured general creditor, look only to the Company for payment thereof, and all liability of the Trustee or such Paying Agent with respect to such trust money, and all liability of the Company as trustee thereof, shall thereupon cease; provided, however, that the Trustee or such Paying Agent, before being required to make any such repayment, may, at the expense of the Company, cause to be published once, in a newspaper published in the English language, customarily published on each Business Day and of general circulation in New York City, notice that such money remains unclaimed and that, after a date specified therein, which shall not be less than 30 days from the date of such publication, any unclaimed balance of such money then remaining shall be repaid to the Company.

The Company authorizes and directs the Paying Agent, from the amounts paid to it, to make payment of the principal of, and interest on, the Securities on the due date for payment set forth in this Indenture and the applicable Security.

The Paying Agent is entitled to make payments net of any taxes or other sums required to be withheld or deducted by any applicable law. If the Paying Agent is, in respect of any payment of principal or interest in respect of the Securities, required by applicable law to withhold or deduct any amount for or on account of any taxes, duties, assessments or governmental charges, it shall give notice of that fact to the Company as soon as it becomes aware of the obligation to withhold or deduct. The Company acknowledges and agrees that the Paying Agent may debit any amount available in any balance held for the Company and apply such amount in satisfaction of taxes. The Paying Agent will timely pay the full amount debited or withheld to the relevant authority in accordance with applicable law. If any taxes become payable with respect to any prior credit to the Company by the Paying Agent, the Company acknowledges that the Paying Agent may debit any balance held for it in satisfaction of such prior taxes; provided , that the Paying Agent notifies the Company as soon as it becomes aware of such taxes

62

payable. The Company shall remain liable for any deficiency and agrees that it shall pay any such deficiency promptly upon notice from the Paying Agent or any authority. If taxes are paid by the Paying Agent or any of its affiliates, the Company agrees that it shall promptly reimburse the Paying Agent for such payment to the extent not covered by withholding from any payment or debited from any balance held for it.

In acting hereunder and in connection with the Securities, the Paying Agent shall act solely as agent of the Company and will not assume any fiduciary duty or other obligation towards, or relationship of agency or trust for or with, any of the beneficial owners or Holders of the Securities. Any funds held by the Paying Agent are held as banker and not subject to the UK FCA Client Money Rules.    In making any payment required hereunder, the Trustee or the Paying Agent (as applicable) shall not be bound to make such payment until satisfied that full payment has been received from or on behalf of the Company by the Trustee or the Paying Agent (as applicable) in cleared funds at the Place of Payment. Upon request, the Company undertakes that it will provide to the Trustee, the Paying Agent or any other agent all documentation and other information required by the Trustee, the Paying Agent or such other agent from time to time needed to comply with applicable law forthwith unless such documentation or information is not reasonably available or cannot be obtained or the provision of such documentation or information or would constitute a breach of applicable law.

SECTION 1004.     Statement by Officers as to Default .

The Company shall deliver to the Trustee, within 120 days after the end of each fiscal year (which fiscal year currently ends on December 31) of the Company ending after the date hereof, an Officer’s Certificate, stating whether or not to the best knowledge of the signers thereof the Company is in default in the performance and observance of any of the terms, provisions and conditions of this Indenture (without regard to any period of grace or requirement of notice provided hereunder) and, if the Company shall be in default, specifying all such defaults and the nature and status thereof of which they may have knowledge.

The Company shall deliver to the Trustee, as soon as possible and in any event within 15 days after the Company becomes aware that a default or an Event of Default, or an event that, with notice or the lapse of time or both, would constitute an Event of Default, as the case may be, has occurred and is continuing, an Officer’s Certificate setting forth the details of such Event of Default or default and the action which the Company proposes to take with respect thereto.

SECTION 1005.     Exchange Act Reports .

The Company shall file with the Trustee, within 15 days after it files the same with the Commission, copies of the information, documents and other reports (or copies of such portions of any of the foregoing as the Commission may by rules and regulations prescribe) which the Company is required to file with the Commission pursuant to Section 13 or 15(d) of the Exchange Act, including its annual reports on Form 20-F and its reports on Form 6-K. In addition, the Company shall make the same information,

63

documents and other reports available, at its expense, to Holders who so request in writing. In the event that, in the future, the Company is not required to file such information, documents or other reports pursuant to Section 13 or 15(d) of the Exchange Act, the Company shall furnish on a reasonably prompt basis to the Trustee and Holders who so request in writing, substantially the same financial and other information that the Company would be required to include and file in an annual report on Form 20-F and reports on Form 6-K. To the extent any Securities are issued pursuant to Rule 144A under the Securities Act and solely with respect to such Securities, the Company agrees that if it is not subject to the reporting requirements of Section 13 or 15(d) of the Exchange Act at any time when the Securities are “restricted securities” within the meaning of Rule 144(a)(3) under the Securities Act, then it shall promptly furnish or cause to be furnished financial and other information described in Rule 144A(d)(4) under the Securities Act (or any successor provision thereto) with respect to the Company to any Holder or to a prospective purchaser of any such Security who is designated by such Holder and is a qualified institutional buyer (as defined in Rule 144A), upon the request of such Holder or prospective purchaser, to the extent required to permit such Holder to comply with Rule 144A under the Securities Act in connection with any resale of Securities held by such Holder.

Delivery of such reports, information and documents to the Trustee is for informational purposes only and the Trustee’s receipt of such shall not constitute constructive notice of any information contained therein or determinable from information contained therein, including the Company’s compliance with any of its covenants hereunder (as to which the Trustee is entitled to rely exclusively on Officer’s Certificates).

SECTION 1006.     Limitation on Liens .

The Company shall not, and shall not permit any Restricted Subsidiary to, create, incur, issue or assume any Lien on any Restricted Property to secure Indebtedness without, in any such case, effectively providing that the Securities (together with, if the Company shall so determine, any other Indebtedness of the Company or any Restricted Subsidiary then existing or thereafter created) shall be secured equally with or prior to such secured Indebtedness for so long as such secured Indebtedness shall be so secured, unless, after giving effect thereto, the aggregate principal amount of all such secured Indebtedness then outstanding (excluding Indebtedness secured by any Lien permitted under subsections (a) through (e) below) plus the aggregate amount of Attributable Debt of the Company and its Restricted Subsidiaries in respect of Sale/Leaseback Transactions then outstanding (other than any Sale/Leaseback Transaction permitted by (i) Clause (b) of the first paragraph of Section 1008, (ii) the proviso to the first paragraph of Section 1008 or (iii) the second paragraph of Section 1008) would not exceed an amount equal to an aggregate of 15% of Consolidated Net Tangible Assets; provided, however, that nothing contained in this Section 1006 shall prevent or restrict:

(a)    any Lien existing on any Restricted Property on the date of acquisition thereof by the Company or any of its Restricted Subsidiaries, or any Lien arising after such acquisition pursuant to contractual commitments entered into prior to such acquisition;

64

(b)    any Lien on any Restricted Property securing Indebtedness incurred or assumed for the purpose of financing the purchase price thereof or the cost of construction, improvement or repair of all or any part thereof; provided that such Lien attaches to such Restricted Property within 12 months after the acquisition thereof or completion of construction, improvement or repair thereof and does not attach to any other Restricted Property;

(c)    any Lien existing on any Restricted Property of any Restricted Subsidiary prior to the time such Restricted Subsidiary becomes a Subsidiary of the Company, or any Lien arising after such time pursuant to contractual commitments entered into prior to and not in contemplation thereof;

(d)    any Lien on any Restricted Property securing Indebtedness owed by a Subsidiary to the Company or to another Subsidiary; or

(e)    any Lien arising out of the refinancing, extension, renewal or refunding of any Indebtedness described in any of subsections (a) through (d) above; provided that the aggregate principal amount of such Indebtedness is not increased and such Lien does not extend to any additional Restricted Property.

For the purposes of this Section 1006, the giving of a guarantee which is secured by a Lien on a Restricted Property, and the creation of a Lien on a Restricted Property to secure Indebtedness which existed prior to the creation of such Lien, shall be deemed to involve the creation of Indebtedness in an amount equal to the principal amount guaranteed or secured by such Lien; but the amount of Indebtedness secured by Liens on Restricted Properties shall be computed without cumulating the underlying Indebtedness with any guarantee thereof or Lien securing the same.

SECTION 1007.     [Reserved] .

SECTION 1008.     Limitation on Sale/Leaseback Transactions .

The Company shall not, and shall not permit any Restricted Subsidiary to, enter into any Sale/Leaseback Transaction without in any such case effectively providing that the Securities (together with, if the Company shall so determine, any other Indebtedness of the Company or any Restricted Subsidiary then existing or thereafter created) shall be secured equally and ratably with or prior to such Sale/Leaseback Transaction, so long as such Sale/Leaseback Transaction shall be outstanding, unless, after giving effect thereto, (a) the aggregate principal amount of all Indebtedness then outstanding secured by any Lien on any Restricted Property, which Lien does not equally and ratably secure the Securities (excluding any Indebtedness secured by any Lien permitted under subsections (a) through (e) of Section 1006) plus the aggregate amount of Attributable Debt of the Company and its Restricted Subsidiaries in respect of Sale/Leaseback Transactions then outstanding (other than any Sale/Leaseback Transaction permitted by

65

(i) Clause (b) of this first paragraph of Section 1008; (ii) the proviso to this first paragraph of Section 1008; or (iii) the second paragraph of this Section 1008) would not exceed an amount equal to 15% of Consolidated Net Tangible Assets or (b) the Company or a Restricted Subsidiary, within 12 months after such Sale/Leaseback Transaction, applies to the retirement of secured Indebtedness of the Company or a Restricted Subsidiary permitted under Section 1006 which is not subordinate to the Securities an amount equal to the greater of (i) the net proceeds of the sale or transfer of the property or other assets that are the subject of such Sale/Leaseback Transaction and (ii) the fair market value of the Restricted Property so leased (in each case as reasonably determined by the Company); provided, however, that nothing contained in this Section 1008 shall prevent or restrict any Sale/Leaseback Transaction in which a Subsidiary of the Company is the lessee and the Company or another Subsidiary is the lessor of such Restricted Property.

In addition, where the Company or any Restricted Subsidiary is the lessee in any Sale/Leaseback Transaction, Attributable Debt shall not include any Indebtedness resulting from the guarantee by the Company or any other Restricted Subsidiary of the lessee’s obligation thereunder.

SECTION 1009.     Payment of Additional Amounts .

(a)    All payments of principal, premium and interest in respect of the Securities shall be made after withholding or deduction for any present or future taxes, duties, assessments or governmental charges of whatever nature imposed, levied, collected, withheld or assessed by or on behalf of Mexico or any authority therein or thereof having power to tax (“Mexican Taxes”). In the event of any withholding or deduction for any Mexican Taxes, the Company shall pay such additional amounts (“Additional Amounts”) as will result in receipt by the Holders of Securities on the respective due dates of such amounts as would have been received by them had no such withholding or deduction (including for any Mexican Taxes payable in respect of Additional Amounts) been required, except that no such Additional Amounts shall be payable with respect to any payment on a Security to the extent:

(i)    that any such taxes, duties, assessments or other governmental charges are imposed solely because of (A) a connection between the Holder and Mexico other than the ownership or holding of such Security and the mere receipt of payments with respect to such Security or (B) failure by the Holder or any other Person to comply with any certification, identification or other reporting requirement concerning the nationality, residence, identity or connection with Mexico of the Holder or any beneficial owner of such Security if compliance is required by law, regulation or by an applicable income tax treaty to which Mexico is a party, as a precondition to exemption from, or reduction in the rate of, the tax, assessment or other governmental charge and the Company has given the Holders at least 30 days’ notice prior to the first payment date with respect to which such certification, identification or reporting requirement is required to the effect that Holders will be required to provide such information and identification;

66

(ii)    of any such taxes, duties, assessments or other governmental charges with respect to a Security presented for payment more than 15 days after the date on which such payment became due and payable or the date on which payment thereof is duly provided for and notice thereof given to Holders, whichever occurs later, except to the extent that the Holder of such Security would have been entitled to such Additional Amounts on presenting such Security for payment on any date during such 15-day period;

(iii)    of any estate, inheritance, gift or other similar taxes, assessments or other governmental charges imposed with respect to a Security;

(iv)    of any tax, duty, assessment or other governmental charge payable otherwise than by deduction or withholding from payments on such Security;

(v)    of any payment on a Security to a Holder that is a fiduciary or partnership or a person other than the sole beneficial owner of any such payment, to the extent that a beneficiary or settlor with respect to such fiduciary, a member of such a partnership or the beneficial owner of such payment would not have been entitled to the Additional Amounts had such beneficiary, settlor, member or beneficial owner been the Holder of such Security; and

(vi)    any combination of the items in Clauses (i) through (v) above.

For purposes of the provisions described in Clause (i) above, the term “Holder” of any Security means the direct nominee of any beneficial owner of such Security, which holds such beneficial owner’s interest in such Security. Notwithstanding the foregoing, the limitations on the Company’s obligation to pay Additional Amounts set forth in Clause (i)(B) above shall not apply if (a) the provision of information, documentation or other evidence described in such Clause (i)(B) would be materially more onerous, in form, in procedure or in the substance of information disclosed, to a Holder or beneficial owner of a Security (taking into account any relevant differences between U.S. and Mexican law, regulation or administrative practice) than comparable information or other reporting requirements imposed under U.S. tax law (including the United States - Mexico Income Tax Treaty), regulations (including proposed regulations) and administrative practice or (b) Article 166, Section II, subsection (a) of the Mexican Income Tax Law (or any substantially similar successor provision, whether included in any law or regulation) is in effect, unless (1) the provision of the information, documentation or other evidence described in such Clause (i)(B) is expressly required by laws and regulations in order to apply Article 166, Section II, subsection (a) of the Mexican Income Tax Law (or any substantially similar successor provision, whether included in any law or regulation), (2) the Company cannot obtain such information, documentation or other evidence on its own through reasonable diligence and (3) the Company, as applicable, otherwise would meet the requirements for application of Article 166, Section II, subsection (a) of the Mexican Income Tax Law (or any substantially similar successor provision, whether included in any law or regulation). In addition, such Clause (i)(B) shall not be construed

67

to require that a non-Mexican pension or retirement fund or a non-Mexican financial institution or any other Person register with the Ministry of Finance and Public Credit for the purpose of establishing eligibility for an exemption from or reduction of Mexican withholding tax.

The Company shall remit the full amount of any Mexican Taxes withheld to the applicable Mexican authorities in accordance with applicable law. The Company shall also provide the Trustee with the constancia or other relevant documentation, if any (which may consist of certified copies of such documentation), satisfactory to the Trustee evidencing the payment of Mexican Taxes in respect of which the Company has paid any Additional Amounts. Copies of such documentation shall be made available to the Holders of the Securities or the Paying Agent, as applicable, upon request therefor.

In respect of the Securities issued hereunder, at least 10 days’ prior to the first date of payment of interest on the Securities and at least 10 days’ prior to each date, if any, of payment of principal or interest thereafter if there has been any change with respect to the matters set forth in the below-mentioned Officer’s Certificate, the Company shall furnish the Trustee and each Paying Agent with an Officer’s Certificate instructing the Trustee and such Paying Agent as to whether such payment of principal of or any interest on such Securities shall be made without deduction or withholding for or on account of any tax, duty, assessment or other governmental charge. If any such deduction or withholding shall be required by Mexico or under the federal laws of the United States, then such certificate shall specify, by country, the amount, if any, required to be deducted or withheld on such payment to Holders of such Securities, and the Company shall pay or cause to be paid to the Trustee or such Paying Agent Additional Amounts, if any, required by this Section 1009. The Company agrees to indemnify the Trustee and each Paying Agent for, and to hold them harmless against, any loss, liability or expense incurred without negligence, bad faith or willful misconduct on their part arising out of or in connection with actions taken or omitted by them in reliance on any Officer’s Certificate furnished pursuant to this Section 1009.

(b)    The Company shall pay all stamp, issue, registration, documentary or other similar duties, if any, which may be imposed by Mexico or any other governmental entity or political subdivision therein or thereof, or any taxing authority of or in any of the foregoing, with respect to this Indenture or the issuance of the Securities.

(c)    The Company shall provide each Paying Agent and any withholding agent under relevant tax regulations with copies of each certificate received by the Company from a Holder of a Security pursuant to the text of such Security. Each such Paying Agent and withholding agent shall retain each such certificate received by it for as long as any Security is outstanding and in no event for less than four years after its receipt, and for such additional period thereafter, as set forth in an Officer’s Certificate, as such certificate may become material in the administration of applicable tax laws.

(d)    In the event that Additional Amounts actually paid with respect to the Securities pursuant to the preceding paragraphs are based on rates of deduction or withholding of withholding taxes in excess of the appropriate rate applicable to the

68

Holder of such Securities, and, as a result thereof such Holder is entitled to make claim for a refund or credit of such excess from the authority imposing such withholding tax, then such Holder shall, by accepting such Securities, be deemed to have assigned and transferred all right, title, and interest to any such claim for a refund or credit of such excess to the Company. However, by making such assignment, the Holder makes no representation or warranty that the Company shall be entitled to receive such claim for a refund or credit and incurs no other obligation with respect thereto.

(e)    All references in this Indenture, one or more supplemental indentures hereto and the Securities to principal, premium, if any, interest or any other amount payable in respect of any Security shall be deemed to include all Additional Amounts, if any, payable in respect of such principal, premium, interest or other amount payable, unless the context otherwise requires, and express mention of the payment of Additional Amounts in any provision hereof shall not be construed as excluding reference to Additional Amounts in those provisions hereof where such express mention is not made. All references in this Indenture, one or more supplemental indentures thereto and the Securities to principal in respect of any Security shall be deemed to mean and include any Redemption Price payable in respect of such Security pursuant to any redemption right hereunder (and all such references to the Stated Maturity of the principal in respect of any Security shall be deemed to mean and include the Redemption Date with respect to any such Redemption Price), and all such references to principal, premium, interest or Additional Amounts shall be deemed to mean and include any amount payable in respect hereof pursuant to this Section 1009.

SECTION 1010.     Indemnification of Judgment Currency .

The Company shall indemnify the Trustee and any Holder of a Security against any loss incurred by the Trustee or such Holder, as the case may be, as a result of any judgment or order being given or made for any amount due under this Indenture or such Security and being expressed and paid in a currency (the “Judgment Currency”) other than Dollars or such other currency in which such Security is denominated (the “Security Currency”), and as a result of any variation between (i) the rate of exchange at which the Security Currency amount is converted into the Judgment Currency for the purpose of such judgment or order and (ii) the spot rate of exchange in New York City at which the Trustee or such Holder, as the case may be, on the date of payment of such judgment or order is able to purchase the Security Currency with the amount of the Judgment Currency actually received by the Trustee or such Holder. Notwithstanding the preceding sentence of this Section 1010, in the event that the amount of the Security Currency purchased by any Holder as a result of such indemnification exceeds the amount originally to be paid to such Holder, such Holder shall reimburse such excess to the Company. The foregoing indemnity shall constitute a separate and independent obligation of the Company and shall continue in full force and effect notwithstanding any such judgment or order as aforesaid. The term “spot rate of exchange” shall include any premiums and costs of exchange payable in connection with the purchase of, or conversion into, the Security Currency.

SECTION 1011.     Waiver of Certain Covenants .

Except as otherwise specified as contemplated by Section 301 for Securities of such series, the Company may, with respect to the Securities of any series, omit in any particular instance to comply with any term, provision or condition set forth in any covenant provided pursuant to Section 301(18), Section 901(2) or Section 901(7) for the benefit of the Holders of such series or in Section 1006 or Section 1007, if before the time for such compliance the Holders of at least a majority in principal amount of the Outstanding Securities of such series shall, by Act of such Holders, either waive such compliance in such instance or generally waive compliance with such term, provision or condition, but no such waiver shall extend to or affect such term, provision or condition except to the extent so expressly waived, and, until such waiver shall become effective, the obligations of the Company and the duties of the Trustee in respect of any such term, provision or condition shall remain in full force and effect.

SECTION 1012.     Calculation of Original Issue Discount .

If the Securities of a series are issued with original issue discount for U.S. federal income tax purposes, the Company shall file with the Trustee promptly at the end of each calendar year (i) a written notice specifying the amount of original issue discount (including daily rates and accrual periods), if any, accrued on Outstanding Securities as of the end of such year and (ii) such other specific information relating to such original issue discount, if any, as may then be relevant under the U.S. Internal Revenue Code of 1986, as amended from time to time.

SECTION 1103.     Deposit of Redemption Price .

SECTION 1104.     Securities Payable on Redemption Date .

Notice of redemption having been given as aforesaid, the Securities so to be redeemed shall, on the Redemption Date, become due and payable at the Redemption Price herein specified, and from and after such date (unless the Company shall default in the payment of the Redemption Price and accrued interest) such Securities shall cease to bear interest. Upon surrender of any such Security for redemption in accordance with said notice, such Security shall be paid by the Company at the Redemption Price, together with accrued interest to the Redemption Date; provided, however, that installments of interest whose Stated Maturity is on or prior to the Redemption Date shall be payable to the Holders of such Securities, or one or more Predecessor Securities, registered as such at the close of business on the relevant Record Dates according to their terms and the provisions of Section 306.

If any Security called for redemption shall not be so paid upon surrender thereof for redemption, the principal shall, until paid, bear interest from the Redemption Date at the rate borne by the Security.

SECTION 1105.     Securities Redeemed in Part .

Any Security which is to be redeemed only in part shall be surrendered at a Place of Payment therefor (with, if the Company or the Trustee so requires, due endorsement by, or a written instrument of transfer in form satisfactory to the Company and the

72

Trustee duly executed by the Holder thereof or his attorney duly authorized in writing), and the Company shall execute, and upon receipt of a Company Order, the Trustee shall authenticate and deliver to the Holder of such Security without service charge, a new Security or Securities of the same series and of like tenor, of any authorized denomination as requested by such Holder, in aggregate principal amount equal to and in exchange for the unredeemed portion of the principal of the Security so surrendered.

SECTION 1206.     Reinstatement .

If the Trustee or any Paying Agent is unable to apply any money or Government Securities in accordance with Section 1204 by reason of any legal proceeding or by reason of any order or judgment of any court or governmental authority enjoining, restraining or otherwise prohibiting such application, the Company’s obligations under this Indenture and the Securities of a series shall be revived and reinstated as though no deposit had occurred pursuant to Section 1204, until such time as the Trustee or such Paying Agent is permitted to apply all such money or Government Securities in accordance with Section 1204; provided that, if the Company has made any payment of principal of or interest on the Securities of such series because of the reinstatement of its obligations, the Company shall be subrogated to the rights of the Holders of the Securities of such series to receive such payment from the money or Government Securities held by the Trustee or such Paying Agent.
