given or taken by Holders may be embodied in and evidenced by one or more instruments of substantially similar tenor signed by such Holders in person or by agent duly appointed in writing; and, except as herein otherwise expressly provided, such
action shall become effective when such instrument or instruments are delivered to the Trustee and, where it is hereby expressly required, to the Company. 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. 

  
 10 

 (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. The fact and date of the execution of any
such instrument or writing, or the authority of the Person executing the same, may also be proved in any other manner which the Trustee deems sufficient. 
 (c) The ownership of Securities shall be proved by the Security Register and the Trustee may rely on such information and shall not be affected by notice to the contrary. 

(d) Any request, demand, authorization, direction, notice, consent, waiver or other Act of the Holder of any Security shall bind every
future Holder of the same Security and the Holder of every Security issued upon the registration of transfer thereof or in exchange therefor or in lieu thereof in respect of anything done, omitted or suffered to be done by the Trustee or the Company
in reliance thereon, whether or not notation of such action is made upon such Security. 
 (e) The Company may set any day as a
record date for the purpose of determining the Holders of Outstanding Securities of any series entitled to give, make or take any request, demand, authorization, direction, notice, consent, waiver or other action provided or permitted by this
Indenture to be given, made or taken by Holders of Securities of such series; provided that the Company may not set a record date for, and the provisions of this paragraph shall not apply with respect to, the giving or making of any notice,
declaration, request or direction referred to in the next paragraph. 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 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. 

  
 11 

 (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. 

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. 

  
 12 

 SECTION 105. Notices, Etc., to Trustee 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 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 at its Corporate Trust Office, or 

(2) the Company by the Trustee 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. 
 Where this Indenture provides for notice to Holders of any event, such notice shall be sufficiently given (unless otherwise herein expressly provided) if in writing and mailed, first-class postage
prepaid, to each Holder affected by such event, at his address as it appears in the Security Register, not later than the latest date (if any), and not earlier than the earliest date (if any), prescribed for the giving of such notice. In any case
where notice to Holders is given by mail, neither the failure to mail such notice, nor any defect in any notice so mailed, to any particular Holder shall affect the sufficiency of such notice with respect to other Holders. Where this Indenture
provides for notice in any manner, such notice may be waived in writing by the Person entitled to receive such notice, either before or after the event, and such waiver shall be the equivalent of such notice. Waivers of notice by Holders shall be
filed with the Trustee, but such filing shall not be a condition precedent to the validity of any action taken in reliance upon such waiver. 
 In case by reason of the suspension of regular mail service or by reason of any other cause it shall be impracticable to give such notice by mail, then such notification as shall be made with the approval
of the Trustee shall constitute a sufficient notification for every purpose hereunder. 

  
 13 

 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 109. Successors and Assigns. 
 All covenants and agreements in this
Indenture by the Company shall bind its successors and assigns, whether so expressed or not. 
 SECTION 110. Separability Clause.

 In case any one or more of the provisions contained in this Indenture shall be invalid, illegal or unenforceable in any
respect, such invalidity, illegality or unenforceability shall not affect any other provisions contained in this Indenture, and to the extent and only to the extent that any such provision is invalid, illegal or unenforceable, this Indenture shall
be construed as if such provision had never been contained herein. 
 SECTION 111. Counterparts. 

This Indenture may be simultaneously executed and delivered in any number of counterparts, each of which so executed and delivered shall
be deemed to be an original, and such counterparts shall together constitute but one and the same instrument. 
 SECTION 112. Benefits of
Indenture.

parties hereto and their successors hereunder and the Holders of Securities, any benefit or any legal or equitable right, remedy or claim under this Indenture.

SECTION 114. Legal Holidays. 
 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 this Indenture or of the
Securities) payment of interest or principal (and premium, if any) 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.

domicile and irrevocably submits to the jurisdiction of any such court in any such suit, action or proceeding. The Company hereby designates and appoints CT Corporation System, 111 Eighth Avenue, 13th Floor, New York, New York 10011, as its authorized agent upon which
process may be served in any legal suit, action or proceeding arising out of or relating to this Indenture or the Securities which may be instituted in any U.S. federal or New York state court in the Borough of Manhattan, The City of New York,

promptly appoint a successor agent for this purpose reasonably acceptable to the Trustee. The Company agrees to take any and all actions as may be necessary to maintain such designation and appointment of such agent in full force and effect.

 SECTION 116. Language of Notices, Etc.

 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 June 28, 2012 (the “Indenture”), between the Company and The Bank of New York Mellon, as Trustee (the “Trustee,” which term includes any successor trustee under the Indenture),
Security 

  
 19 

 
Registrar, Paying Agent and Transfer 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,

 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.] 

  
 20 

 [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”). 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 we have 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; 

  
 21 

 (ii) of any such taxes, duties, assessments or other governmental charges
with respect to such 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 estate, inheritance, gift or other similar taxes, assessments or other governmental charge imposed with respect
to such 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 such Security to a Holder who
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; 
 (vi) of any tax, duty, assessment or other governmental charge imposed on a payment to an individual and required to be made pursuant to European Council Directive 2003/48/EC on the taxation of savings
income or any other directive implementing the conclusions of the ECOFIN Council meetings of November 26 and 27, 2000, December 13, 2001, and January 21, 2003, or any law or agreement implementing or complying with, or introduced
in order to conform to, such a directive; and 
 (vii) any combination of the items in Clauses (i) through
(vi) 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 

  
 22 

 
practice or (b) Rule I.3.17.11 (or any successor provision) is in effect, unless the provision of the information, documentation or other evidence described in such Clause (i)(B) is
expressly required by statute, regulation, rule or administrative practice in order to apply Rule I.3.17.11 (or any successor provision) and the Company cannot obtain such information, documentation or other evidence on its own through reasonable
diligence and the Company otherwise would meet the requirements for application of Rule I.3.17.11 (or any successor provision). In addition, such Clause (i)(B) shall not be construed 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 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 any Paying Agent, as applicable, upon request therefor. 
 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. 
 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 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. 

  
 23 

 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 original issue discount thereon to the Redemption Date, (C) any accrued and unpaid interest thereon to the Redemption Date, (D) any premium applicable in the case of redemption prior to Maturity and (E) 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 making reasonable endeavors 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 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. 
 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 herefor or in lieu hereof, whether or not notation of such consent or waiver is made upon this Security. 

  
 24 

 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 reasonably 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. 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 Security 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 Security 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. 

  
 25 

 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.

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.

 SECTION 303. Execution, Authentication,
Delivery and Dating. 
 The Securities shall be executed on behalf of the Company by any two of its Chief Executive Officer,
its Treasurer, its Chief Financial Officer, its General Counsel or any Division Head. The signature of any of these officers on the Securities may be manual or facsimile. 
 Securities bearing the manual or facsimile signatures of individuals who were at any time the proper officers of the Company shall bind the Company, notwithstanding that such individuals or any of them
have ceased to hold such offices prior to the authentication and delivery of such Securities or did not hold such offices at the date of such Securities. 

  
 29 

 At any time and from time to time after the execution and delivery of this Indenture, the
Company may deliver Securities of any series executed by the Company to the Trustee for authentication, together with a Company Order for the authentication and delivery of such Securities, and the Trustee in accordance with such Company Order shall
authenticate and deliver such Securities. If the form or terms of the Securities of the series have been established by or pursuant to one or more Board Resolutions as permitted by Sections 201 and 301, in authenticating such Securities, and
accepting the additional responsibilities under this Indenture in relation to such Securities, the Trustee shall be entitled to receive, and (subject to Section 601) shall be fully protected in relying upon, an Opinion of Counsel stating:

 (1) if the form of such Securities has been established by or pursuant to Board Resolution as permitted by
Section 201, that such form has been established in conformity with the provisions of this Indenture; 
 (2)
if the terms of such Securities have been established by or pursuant to Board Resolution as permitted by Section 301, that such terms have been established in conformity with the provisions of this Indenture; and 

(3) that such Securities, when authenticated and delivered by the Trustee and issued by the Company in the manner and
subject to any conditions specified in such Opinion of Counsel, shall constitute valid and legally binding obligations of the Company enforceable in accordance with their terms, subject to bankruptcy, insolvency, fraudulent transfer, reorganization,
moratorium and similar laws of general applicability relating to or affecting creditors’ rights and to general equity principles. 
 If such form or terms have been so established, the Trustee shall not be required to authenticate such Securities if, in the opinion of counsel to the Trustee, the issue of such Securities pursuant to
this Indenture will affect the Trustee’s own rights, duties or immunities under the Securities and this Indenture. 

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. 

  
 30 

 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 “Security 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 “Security Registrar” for the purpose of registering Securities and transfers of 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 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. 

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 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 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 Security 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 1105 not involving any
transfer. 

  
 31 

 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 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 Security Registrar. With regard to any Global
Security to be 

  
 32 

 
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, 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. 

SECTION 305. Mutilated, Destroyed, Lost and Stolen Securities. 
 If any mutilated Security is surrendered to the Trustee, the Company shall execute and 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 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. 

  
 33 

 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 Trustee an amount of money equal to the aggregate amount
proposed to be paid in respect of such Defaulted Interest or shall make arrangements satisfactory to the Trustee for such deposit prior to the date of the proposed payment, such money when deposited to be held in trust for the benefit of the Persons
entitled to such Defaulted Interest as in this Clause provided. Thereupon the Trustee shall fix a Special Record Date for the payment of such 

  
 34 

 
Defaulted Interest which shall be not more than 15 days and not less than 10 days prior to the date of the proposed payment and not less than 10 days after the receipt by the
Trustee of the notice of the proposed payment. The Trustee shall promptly notify the 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 Security 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. 

  
 35 

 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. 
 ARTICLE FOUR 

SATISFACTION AND DISCHARGE 

SECTION 401. Satisfaction and Discharge of Indenture. 
 This Indenture shall cease to be of further effect (except as to any surviving rights of registration of transfer or exchange of Securities herein expressly provided for), and the Trustee, on demand of
and at the expense of the Company, shall execute proper instruments acknowledging satisfaction and discharge of this Indenture, when

 (A) all Securities theretofore authenticated and
delivered (other than (i) Securities which have been destroyed, lost or stolen and which have been replaced or paid as provided in Section 305 and (ii) Securities for whose payment money has theretofore been deposited in trust or
segregated and held in trust by the Company and thereafter repaid to the Company or discharged from such trust, as provided in Section 1003) have been delivered to the Trustee for cancellation; or

cancellation 
 (i) have become due and payable, or 

(ii) will become due and payable at their Stated Maturity within one year, or 

(iii) are to be called for redemption within one year under arrangements satisfactory to the Trustee for the giving of
notice of redemption by the Trustee in the name, and at the expense, of the Company, 
 and the Company, in the case of Clause
(i), (ii) or (iii) above, has deposited or caused to be deposited with the Trustee as trust funds in trust for the purpose funds in an amount sufficient to pay and discharge the entire indebtedness on such Securities not theretofore
delivered to the Trustee for cancellation, for principal (and premium, if any) and interest to the date of such deposit (in the case of Securities which have become due and payable) or to the Stated Maturity or Redemption Date, as the case may be;

 (2) the Company has paid or caused to be paid all other sums payable hereunder by the Company; and 

(3) the Company has delivered to the Trustee an Officer’s Certificate and an Opinion of Counsel, each stating that
all conditions precedent herein provided for relating to the satisfaction and discharge of this Indenture have been complied with. 
 Notwithstanding the satisfaction and discharge of this Indenture, the obligations of the Company to the Trustee under Section 607, the obligations of the Trustee to any Authenticating Agent under
Section 614 and, if money shall have been deposited with the Trustee pursuant to subclause (B) of Clause (1) of this Section 401, the obligations of the Trustee under Section 402 and the last paragraph of Section 1003
shall survive such satisfaction and discharge. 
 SECTION 402. Application of Trust Money. 

Subject to the provisions of the last paragraph of Section 1003, all money deposited with the Trustee pursuant to Section 401
shall be held in trust and applied by it, in accordance with the provisions of the Securities and this Indenture, to the payment, either directly or through any Paying Agent (including the Company acting as its own Paying Agent) as the Trustee may
determine, to the Persons entitled thereto, of the principal (and premium, if any) and interest for whose payment such money has been deposited with the Trustee. All moneys deposited with the Trustee pursuant to Section 401 (and held by it or
any Paying Agent) for the payment of Securities subsequently converted shall be returned to the Company upon Company Request. 

  
 37

 39 

 SECTION 502. Acceleration of Maturity; Rescission and Annulment. 

If an Event of Default with respect to any series of Securities (other than an Event of Default specified in Section 501(6) or
(7)) occurs and is continuing, then and in every such case the Trustee shall, at the written request of the Holders of not less than 25% in principal amount of the Outstanding Securities of that series, by notice in writing to the Company,
declare the principal of all the Securities to be due and payable immediately, and upon any such declaration such principal and any accrued interest and any unpaid Additional Amounts thereon shall become immediately due and payable. If an Event of
Default specified in Sections 501(6) and (7) with respect to Securities of any series at the time Outstanding occurs and is continuing, the principal and any accrued interest, together with any Additional Amounts thereon, on all of the
Securities of that series then Outstanding shall automatically, and without any declaration or other action on the part of the Trustee or any Holder, become immediately due and payable. 

At any time after such a declaration of acceleration with respect to Securities of any series at the time Outstanding has been made and
before a judgment or decree for payment of the money due has been obtained by the Trustee as hereinafter in this Article Five provided, the Holders of a majority in aggregate principal amount of the Outstanding Securities of that series, by written
notice to the Company and the Trustee, may rescind and annul such declaration and its consequences if 
 (1) the
Company has paid or deposited with the Trustee a sum sufficient to pay 
 (A) all overdue interest and any
Additional Amounts thereon on all of the Securities of that series, 
 (B) the principal of any Securities of
that series which have become due otherwise than by such declaration of acceleration, 
 (C) to the extent that
payment of such interest is lawful, interest upon overdue interest at the rate borne by the Securities of that series, and 
 (D) all sums paid or advanced by the Trustee hereunder and all amounts owing the Trustee under Section 607; 
 and 
 (2) all Events of Default, other than the non-payment of the
principal of Securities which have become due solely by such declaration of acceleration, have been cured or waived as provided in Section 513. 

  
 40 

 No such rescission shall affect any subsequent default or impair any right consequent
thereon. 
 SECTION 503. Collection of Indebtedness and Suits for Enforcement by Trustee. 

The Company covenants that if: 
 (1) default is made in the payment of any interest (including any Additional Amounts) on any Security when such interest becomes due and payable and such default continues for a period of 30 days, or

 (2) default is made in the payment of the principal (including any Redemption Price) of (or premium, if any,
on) any Security at the Maturity thereof, 
 the Company shall, upon demand of the Trustee, pay to it, for the benefit of the Holders of such
Securities, the whole amount then due and payable on such Securities for principal and any premium and interest, and, to the extent that payment of such interest shall be legally enforceable, interest on any overdue principal and premium and on any
overdue interest, at the rate borne by such Securities, together with any Additional Amounts thereon, and, in addition thereto, such further amount as shall be sufficient to cover the costs and expenses of collection, including the reasonable
compensation, expenses, disbursements and advances of the Trustee, its agents and counsel, and all amounts due the Trustee under Section 607. 
 If an Event of Default with respect to Securities of any series occurs and is continuing, the Trustee may in its discretion proceed to protect and enforce its rights and the rights of the Holders of that
series by such appropriate judicial proceedings as the Trustee shall deem most effectual to protect and enforce any such rights, whether for the specific enforcement of any covenant or agreement in this Indenture or in aid of the exercise of any
power granted herein, or to enforce any other proper remedy. 
 SECTION 504. Trustee May File Proofs of Claim. 

In case of any judicial proceeding relative to the Company (or any other obligor upon the Securities), its property or its creditors, the
Trustee shall be entitled and empowered, by intervention in such proceeding or otherwise, to take any and all actions authorized under the Trust Indenture Act in order to have claims of the Holders and the Trustee allowed in any such proceeding. In
particular, the Trustee shall be authorized to collect and receive any moneys or other property payable or deliverable on any such claims and to distribute the same; and any custodian, receiver, assignee, trustee, liquidator, sequestrator or other
similar official in any such judicial proceeding is hereby authorized by each Holder to make such payments to the Trustee and, in the event that the Trustee shall consent to the making of such payments directly to the Holders, to pay to the Trustee
any amount due it for the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel, and any other amounts due the Trustee under Section 607. 

  
 41 

 No provision of this Indenture shall be deemed to authorize the Trustee to authorize or
consent to or accept or adopt on behalf of any Holder any plan of reorganization, arrangement, adjustment or composition affecting the Securities or the rights of any Holder thereof or to authorize the Trustee to vote in respect of the claim of any
Holder in any such proceeding; provided, however, that the Trustee may, on behalf of the Holders, vote for the election of a trustee in bankruptcy or similar official and be a member of a creditors’ or other similar committee.

 SECTION 505. Trustee May Enforce Claims Without Possession of Securities. 

All rights of action and claims under this Indenture or the Securities may be prosecuted and enforced by the Trustee without the
possession of any of the Securities or the production thereof in any proceeding relating thereto, and any such proceeding instituted by the Trustee shall be brought in its own name as trustee of an express trust, and any recovery of judgment shall,
after provision for the payment of the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel, be for the ratable benefit of the Holders of the Securities in respect of which such judgment has been
recovered. 
 SECTION 506. Application of Money Collected. 
 Any money collected by the Trustee pursuant to this Article Five shall be applied in the following order, at the date or dates fixed by the Trustee and, in case of the distribution of such money on
account of principal or any premium or interest, upon presentation of the Securities and the notation thereon of the payment if only partially paid and upon surrender thereof if fully paid: 

FIRST: To the payment of all amounts due the Trustee under Section 607; 

SECOND: To the payment of the amounts then due and unpaid for principal of and any premium and interest on the Securities
in respect of which or for the benefit of which such money has been collected, ratably, without preference or priority of any kind, according to the amounts due and payable on such Securities for principal and any premium and interest, respectively;
and 
 THIRD: Any remaining amounts shall be repaid to the Company. 

  
 42 

 SECTION 507. Limitation on Suits. 

No Holder of any Securities of any series shall have any right to institute any proceeding, judicial or otherwise, with respect to this
Indenture, or for the appointment of a receiver or trustee, or for any other remedy hereunder, unless 
 (1) such
Holder has previously given written notice to the Trustee of a continuing Event of Default with respect to the Securities of that series; 
 (2) the Holders of not less than 25% in principal amount of the Outstanding Securities of that series shall have made written request to the Trustee to institute action or proceedings in respect of such
Event of Default in its own name as Trustee hereunder; 
 (3) such Holder or Holders have offered to the Trustee
indemnity reasonably satisfactory to the Trustee against the costs, expenses and liabilities to be incurred in compliance with such request; 
 (4) the Trustee for 60 days after its receipt of such notice, request and offer of indemnity has failed to institute any such action or proceeding; and 

(5) no direction inconsistent with such written request has been given to the Trustee during such 60-day period by the
Holders of a majority in principal amount of the Outstanding Securities of that series; 
 it being understood and intended that
no one or more of such Holders shall have any right in any manner whatever by virtue of, or by availing of, any provision of this Indenture to affect, disturb or prejudice the rights of any other of such Holders, or to obtain or to seek to obtain
priority or preference over any other of such Holders or to enforce any right under this Indenture, except in the manner herein provided and for the equal and ratable benefit of all of such Holders. For the protection and enforcement of the
provisions of this Section 507, each and every Holder of the Outstanding Securities of any series and the Trustee shall be entitled, subject to Section 513, to such relief as can be given at law or in equity. 

SECTION 508. Unconditional Right of Holders to Receive Principal, Premium and Interest and to Convert. 

Notwithstanding any other provision in this Indenture, the Holder of any Security shall have the right, which is absolute and
unconditional, to receive payment of the principal of and any premium and (subject to Section 306) interest on such Security on the respective Stated Maturities expressed in such Security (or, in the case of redemption, on the Redemption Date).

  
 43 

 SECTION 509. Restoration of Rights and Remedies. 

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

SECTION 510. Rights and Remedies Cumulative. 
 Except as otherwise provided with respect to the replacement or payment of mutilated, destroyed, lost or stolen Securities in the last paragraph of Section 305, no right or remedy herein conferred
upon or reserved to the Trustee or to the Holders is intended to be exclusive of any other right or remedy, and every right and remedy shall, to the extent permitted by law, be cumulative and in addition to every other right and remedy given
hereunder or now or hereafter existing at law or in equity or otherwise. The assertion or employment of any right or remedy hereunder, or otherwise, shall not prevent the concurrent assertion or employment of any other appropriate right or remedy.

 SECTION 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. Every right and remedy given by this Article Five or by law to the Trustee or to the Holders may be exercised from time to time, and as often as may be deemed expedient, by the Trustee or by the
Holders, as the case may be. 
 SECTION 512. Control by Holders. 
 The Holders of a majority in principal amount of the Outstanding Securities of any series shall have the right to direct the time, method and place of conducting any proceeding for any remedy available to
the Trustee or exercising any trust or power conferred on the Trustee, with respect to the Securities of such series; provided that 
 (1) such direction shall not be in conflict with any rule of law or with this Indenture, and 
 (2) the Trustee may take any other action deemed proper by the Trustee which is not inconsistent with such direction. 

  
 44 

 SECTION 513. Waiver of Past Defaults. 

Subject to Section 502, the Holders of not less than a majority in principal amount of the Outstanding Securities of any series may
on behalf of the Holders of all the Securities of such series waive any past default hereunder with respect to such series and its consequences, except a default 

(1) in the payment of the principal of or any premium or interest on any Security of such series, or 

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

SECTION 514. Undertaking for Costs. 
 In any suit for the enforcement of any right or remedy under this Indenture, or in any suit against the Trustee for any action taken, suffered or omitted by it as Trustee, a court may require any party
litigant in such suit to file an undertaking to pay the costs of such suit, and may assess costs, including reasonable attorneys’ fees and expenses, against any such party litigant, in the manner and to the extent provided in the Trust
Indenture Act; provided that neither this Section 514 nor the Trust Indenture Act shall be deemed to authorize any court to require such an undertaking or to make such an assessment in any suit instituted by the Company or the Trustee or
to require the Company to repurchase any Security in accordance with its terms. 
 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. 

  
 45 

 ARTICLE SIX 
 THE TRUSTEE 
 SECTION 601. Certain Duties and Responsibilities. 

The duties and responsibilities of the Trustee shall be as provided by the Trust Indenture Act. Notwithstanding the foregoing, no
provision of this Indenture shall require the Trustee to expend or risk its own funds or otherwise incur any financial liability in the performance of any of its duties hereunder, or in the exercise of any of its rights or powers, if it shall have
reasonable grounds for believing that repayment of such funds or adequate indemnity against such risk or liability is not reasonably assured to it. Whether or not therein expressly so provided, every provision of this Indenture relating to the
conduct or affecting the liability of or affording protection to the Trustee shall be subject to the provisions of this Section 601. 

SECTION 602. Notice of Defaults. 
 If a default occurs hereunder with respect to Securities of any series, the Trustee shall give the Holders of Securities of such series notice of such default as and to the extent provided by the Trust
Indenture Act; provided, however, that in the case of any default of the character specified in Section 501(3) with respect to Securities of such series, no such notice to Holders shall be given until at least 30 days after the
occurrence thereof. For the purpose of this Section 602, the term “default” means any event which is, or after notice or lapse of time or both would become, an Event of Default with respect to Securities of such series.

 46 

 (d) the Trustee may consult with counsel of its own choice and the advice of

(e) the Trustee shall be under no obligation to exercise any of the rights or powers vested in it by this Indenture at the

compliance with such request or direction; 
 (f) the Trustee shall not be bound to make any investigation into
the facts or matters stated in any resolution, certificate, statement, instrument, opinion, report, notice, request, direction, consent, order, bond, debenture, note, other evidence of indebtedness or other paper or document in connection with this
Indenture, but the Trustee, in its discretion, may make such further inquiry or investigation into such facts or matters as it may see fit, and, if the Trustee shall determine to make such further inquiry or investigation, it shall be entitled to
examine the books, records and premises of the Company, personally or by agent or attorney and shall incur no liability or additional liability of any kind by reason of such inquiry or investigation; 

(g) the Trustee may execute any of the trusts or powers hereunder or perform any duties hereunder either directly or by or
through agents or attorneys and the Trustee shall not be responsible for any misconduct or negligence on the part of any agent or attorney appointed with due care by it hereunder; provided that the Trustee shall be required to terminate any
such agent if it has actual knowledge of any failure by such agent to perform its delegated duties; 
 (h) the
Trustee shall not be deemed to have notice of any default or Event of Default unless a Responsible Officer of the Trustee has actual knowledge thereof or unless written notice of any event which is in fact such a default is received by the Trustee
at the Corporate Trust Office of the Trustee, and such notice references the Securities and this Indenture; 

(i) the permissive rights of the Trustee enumerated herein shall not be construed as duties; 

(j) in no event shall the Trustee be liable for any special, indirect, punitive, incidental or consequential loss or
damage of any kind whatsoever (including, without limitation, loss of profit), even if the Trustee has been advised as to the likelihood of such loss or damage and regardless of the form of action; and 

  
 47 

 (k) in no event shall the Trustee be responsible or liable for any failure
or delay in the performance of its obligations hereunder arising out of or caused by, directly or indirectly, forces beyond its control, including strikes, work stoppages, accidents, acts of war or terrorism, civil or military disturbances, nuclear
or natural catastrophes or acts of God, and interruptions, loss or malfunctions of utilities, communications or computer (software and hardware) services; provided that the Trustee shall use reasonable efforts which are consistent with accepted
practices in the banking industry to resume performance as soon as practicable under the circumstances. 
 SECTION 604. Not Responsible for
Recitals or Issuance of Securities. 
 Neither the Trustee nor any Authenticating Agent assume any responsibility for the
correctness of the recitals contained herein and in the Securities, except the Trustee’s certificates of authentication. The Trustee makes no representations as to the validity or sufficiency of this Indenture or of the Securities, except that
the Trustee represents that it is duly authorized to execute and deliver this Indenture, authenticate the Securities and perform its obligations hereunder. Neither the Trustee nor any Authenticating Agent shall be accountable for the use or
application by the Company of Securities or the proceeds thereof. 
 SECTION 605. May Hold Securities. 

The Trustee, any Authenticating Agent, any Paying Agent, any Security 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 Sections 608 and 613, may otherwise deal with the Company with the same rights it would have if it were not Trustee, Authenticating Agent, Paying Agent, Security
Registrar or such other agent. 
 SECTION 606. Money Held in Trust. 

Money held by the Trustee in trust hereunder need not be segregated from other funds except to the extent required by law. The Trustee
shall be under no liability for interest on any money received by it hereunder except as otherwise agreed in writing with the Company. 

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; and 

  
 48 

 (3) to fully indemnify each of the Trustee and any predecessor Trustee for,
and to hold it harmless against, any and all losses, liabilities, damages, claims or expenses incurred without negligence or willful misconduct on its part, arising out of or in connection with the acceptance or administration of the trust or trusts
hereunder, including the costs and expenses of defending itself against any claim (whether asserted by the Company, a Holder or any other Person) or liability in connection with the exercise or performance of any of its powers or duties hereunder.

 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, except for such money and property which is held in trust to pay principal (and premium, if any) or interest on particular Securities. 

When the Trustee incurs expenses or renders services in connection with an Event of Default specified in Section 501(6) or
Section 501(7), the expenses (including the reasonable charges and expenses of its counsel) and the compensation for the services are intended to constitute expenses of administration under any applicable Federal or State bankruptcy, insolvency
or other similar law. 
 The provisions of this Section 607 shall survive the resignation or removal of the Trustee and the
termination of this Indenture. 
 SECTION 608. Conflicting Interests. 

If the Trustee has or shall acquire a conflicting interest within the meaning of the Trust Indenture Act, the Trustee shall either
eliminate such interest or resign, to the extent and in the manner provided by, and subject to the provisions of, the Trust Indenture Act and this Indenture. To the extent permitted by the Trust Indenture Act, the Trustee shall not be deemed to have
a conflicting interest by virtue of being a trustee under this Indenture with respect to Securities of more than one series. 
 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 

  
 49 

 
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. 
 No resignation or removal of the Trustee and no appointment of a successor Trustee pursuant to this Article Six shall become effective until the acceptance of appointment by the successor Trustee in
accordance with the applicable requirements of Section 611. 
 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 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. 

  
 50 

 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 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 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 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. 

  
 51 

 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 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. 
 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. 

  
 52 

 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 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. 

  
 53 

 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 Security 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. 
 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

required for any such supplemental indenture, or the consent of whose Holders is required for any waiver (of compliance with certain provisions of this Indenture or certain defaults hereunder and their consequences) provided for in this Indenture,
or 

  
 59 

 (3) modify any of the provisions of this Section 902, Section 513
or Section 1011, except to increase any such percentage or to provide that certain other provisions of this Indenture cannot be modified or waived without the consent of the Holder of each Outstanding Security affected thereby; provided,
however, that this Clause (3) shall not be deemed to require the consent of any Holder with respect to changes in the references to “the Trustee” and concomitant changes in this Section 902 and Section 1011, or the
deletion of this proviso, in accordance with the requirements of Section 611. 
 A supplemental indenture which changes or
eliminates any covenant or other provision of this Indenture which has expressly been included solely for the benefit of one or more particular series of Securities, or which modifies the rights of the Holders of Securities of such series with
respect to such covenant or other provision, shall be deemed not to affect the rights under this Indenture of the Holders of Securities of any other series. 
 It shall not be necessary for any Act of Holders under this Section 902 to approve the particular form of any proposed supplemental indenture, but it shall be sufficient if such Act shall approve the
substance thereof. 
 SECTION 903. Execution of Supplemental Indentures. 

In executing, or accepting the additional trusts created by, any supplemental indenture permitted by this Article Nine or the
modifications thereby of the trusts created by this Indenture, the Trustee shall be entitled to receive, in addition to the documents required under Section 102, and (subject to Section 601) shall be fully protected in relying upon, an
Opinion of Counsel stating that the execution of such supplemental indenture is authorized or permitted by this Indenture. The Trustee may, but shall not be obligated to, enter into any such supplemental indenture which affects the Trustee’s
own rights, duties or immunities under this Indenture or otherwise. 
 SECTION 904. Effect of Supplemental Indentures. 

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

SECTION 905. Conformity with Trust Indenture Act. 
 Subsequent to the qualification of this Indenture under the Trust Indenture Act, every supplemental indenture executed pursuant to this Article Nine shall conform to the requirements of the Trust
Indenture Act. 

  
 60 

 SECTION 906. Reference in Securities to Supplemental Indentures. 

Securities of any series authenticated and delivered after the execution of any supplemental indenture pursuant to this Article Nine may,
and shall if required by the Trustee, bear a notation in form approved by the Trustee as to any matter provided for in such supplemental indenture. If the Company shall so determine, new Securities of any series so modified as to conform, in the
opinion of the Trustee and the Company, to any such supplemental indenture may be prepared and executed by the Company and authenticated and delivered by the Trustee in exchange for Outstanding Securities of such series. 

ARTICLE TEN 

COVENANTS 
 SECTION 1001.
Payment of Principal, Premium and Interest. 
 The Company shall duly and punctually pay the principal of and any premium
and interest (together with any Additional Amounts payable thereon) on the Securities in accordance with the terms of the Securities and this Indenture. 
 SECTION 1002. Maintenance of Office or Agency. 
 With respect to any Global
Security, and except as otherwise may be specified for such Global Security as contemplated by Section 301, the Corporate Trust Office of the Trustee shall be the Place of Payment where such Global Security may be presented or surrendered for
payment or for registration of transfer or exchange, or where successor Securities may be delivered in exchange therefor; provided, however, that any such payment, presentation, surrender or delivery effected pursuant to the Applicable
Procedures of the Depositary for such Global Security shall be deemed to have been effected at the Place of Payment for such Global Security in accordance with the provisions of this Indenture. 

With respect to any securities that are not in the form of a Global Security, the Company shall maintain, in the Borough of Manhattan,
New York City, an office or agency where Securities may be presented or surrendered for payment, where Securities may be surrendered for registration of transfer or exchange and where notices and demands to or upon the Company in respect of the
Securities and this Indenture may be served. The Company shall give prompt written notice to the Trustee of the location, and any change in the location, of such office or agency. If at any time the Company shall fail to maintain any such required
office or agency or shall fail to furnish the Trustee with the address thereof, such presentations, surrenders, notices and demands may be made or served at the Corporate Trust Office of the Trustee, and the Company hereby appoints the Trustee as
its agent to receive all such presentations, surrenders, notices and demands. 

  
 61 

 The Company may also from time to time designate one or more other offices or agencies (in
or outside the Borough of Manhattan, New York City) where the Securities of one or more series, notices and other items may be presented or surrendered for any or all such purposes and may from time to time rescind such designations; provided,
however, that no such designation or rescission shall in any manner relieve the Company of its obligation to maintain an office or agency in the Borough of Manhattan, New York City for such purposes. The Company shall give prompt written notice
to the Trustee of any such designation or rescission and of any change in the location of any such other office or agency. 
 SECTION 1003.
Money for Security Payments to Be Held in Trust. 
 If the Company shall at any time act as its own Paying Agent with
respect to any series of Securities, it shall, on or before each due date of the principal of or any premium or interest on any of the Securities of that series, segregate and hold in trust for the benefit of the Persons entitled thereto a sum
sufficient to pay the principal and any premium and interest so becoming due until such sums shall be paid to such Persons or otherwise disposed of as herein provided and shall promptly notify the Trustee of its action or failure so to act.

 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 Company (or any other obligor upon the Securities of that series) in the making
of any payment in respect of the Securities of that series, upon the written request of the Trustee, forthwith pay to the Trustee all sums held in trust by such Paying Agent for payment in respect of the Securities of that series. 

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 held in trust by the Company or such Paying Agent, such sums to be held by the Trustee upon the same trusts as those upon which such sums were held by the Company or such
Paying Agent; and, upon such payment by any Paying Agent to the Trustee, such Paying Agent shall be released from all further liability with respect to such money. 

  
 62 

 Any money deposited with the Trustee 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. 
 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 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, 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

  
 63 

 
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 such 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. Limitation on Sale of Capital Stock of Telcel. 

The Company shall not, and shall not allow any of its Subsidiaries to, sell, transfer or otherwise dispose of any shares of capital stock
of Telcel if following such sale, transfer or disposition the Company would own, directly or indirectly, less than (1) 50% of the voting power of all of the shares of capital stock of Telcel and (2) 50% of all of the shares of capital
stock of Telcel. 
 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 

  
 65 

 
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 (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 

  
 66 

 
rate of, the tax, assessment or other governmental charge and we have 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; 
 (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 estate, inheritance, gift or other
similar taxes, assessments or other governmental charge 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 who 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;

 (vi) of any tax, duty, assessment or other governmental charge imposed on a payment to an individual and
required to be made pursuant to European Council Directive 2003/48/EC on the taxation of savings income or any other directive implementing the conclusions of the ECOFIN Council meetings of November 26 and 27, 2000, December 13, 2001,
and January 21, 2003, or any law or agreement implementing or complying with, or introduced in order to conform to, such a directive; and 
 (vii) any combination of the items in Clauses (i) through (vi) 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 

  
 67 

 
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) Rule I.3.17.11 (or any successor provision) is in effect, unless the provision of the information, documentation or other evidence described in such Clause (i)(B) is expressly required by statute, regulation, rule or administrative
practice in order to apply Rule I.3.17.11 (or any successor provision) and the Company cannot obtain such information, documentation or other evidence on its own through reasonable diligence and the Company otherwise would meet the requirements
for application of Rule I.3.17.11 (or any successor provision). In addition, such Clause (i)(B) shall not be construed 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 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 reasonably incurred without negligence or bad faith 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. 

  
 68 

 (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 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 

  
 69 

 
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), 901(2) or 901(7) for the benefit of the Holders of such series or in
Section 1006 or 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. 
 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. 

ARTICLE ELEVEN 

REDEMPTION OF SECURITIES 

SECTION 1101. Right of Redemption. 
 (a) The Securities of any series which are redeemable before their Stated Maturity may not be redeemed at the election of the Company except in accordance with their terms and (except as otherwise
specified as contemplated by Section 301 for such Securities) in accordance with the provisions of this Article Eleven. 

  
 70 

 (b) The election of the Company to redeem any Securities shall be evidenced by a Board
Resolution. In case of any redemption at the election of the Company of less than all the Securities of any series, the Company shall, at least 45 days prior to the Redemption Date fixed by the Company, notify the Trustee of such Redemption Date, of
the principal amount of Securities of such series to be redeemed and, if applicable, of the tenor of the Securities to be redeemed. 
 (c) If, as a result of any amendment to, or change in, the laws (or any rules or regulation 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 or change of such laws, rules or regulations becomes effective on or after the date of issuance of the Securities of any
series, the Company would be obligated to pay on the next succeeding Interest Payment Date Additional Amounts in respect of interest payments on the Securities of such series pursuant to the terms and conditions thereof in excess of those
attributable to the Mexican withholding tax on the basis of a statutory rate of 4.9% imposed on interest payments with respect to such series of Securities, and if such obligation cannot be avoided by the Company after taking measures the Company
considers reasonable to avoid it, then, at the Company’s option, the Securities of such series may be redeemed in whole, but not in part, at any time, on giving not less than 30 nor more than 60 days’ notice to the Trustee and the
Holders of such Securities, at a Redemption Price equal to 100% of the principal amount thereof and any premium applicable thereto, together with accrued interest up to but not including the Redemption Date and any Additional Amounts which would
otherwise be payable; provided, however, that (1) no notice of such redemption 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 were a payment on such Securities then due, and (2) at the time such notice is given, such obligation to pay such Additional Amounts remains in effect. 
 (d) Before any notice of redemption pursuant to Section 1101(c) is given to the Trustee or the Holders of Securities of the relevant series, the Company shall deliver to the Trustee (i) an
Officer’s Certificate stating that the Company is entitled to effect such redemption and setting forth a statement of facts showing that the condition or conditions precedent to the right of the Company so to redeem have occurred or been
satisfied and (ii) an Opinion of Counsel from Mexican legal counsel (which may be the Company’s outside counsel) of recognized standing to the effect that the Company has or shall become obligated to pay such Additional Amounts as a result
of such change or amendment. Such notice, once given to the Trustee, shall be irrevocable. 
 SECTION 1102. Notice of Redemption.

 Notice of redemption shall be given by first-class mail, postage prepaid, mailed not less than 30 nor more than 60 days
prior to the Redemption Date, to each Holder of Securities to be redeemed, at his address appearing in the Security Register. 

  
 71 

 All notices of redemption shall state: 

(1) the Redemption Date, 
 (2) the Redemption Price and amount of accrued interest, if any, 

(3) that on the Redemption Date the Redemption Price and any accrued interest shall become due and payable upon each
Security to be redeemed and that interest thereon shall cease to accrue on and after said date, 
 (4) the place
or places where such Securities are to be surrendered for payment of the Redemption Price and any accrued interest, and 
 (5) applicable “CUSIP” and “ISIN” numbers. 
 Notice of
redemption of Securities to be redeemed at the election of the Company shall be given by the Company or, at the Company’s request, by the Trustee in the name and at the expense of the Company, and such notice, when given to the Holders, shall
be irrevocable. 
 SECTION 1103. Deposit of Redemption Price. 
 On the Business Day prior to any Redemption Date, the Company shall deposit with the Trustee or with a Paying Agent (or, if the Company is acting as its own Paying Agent, segregate and hold in trust as
provided in Section 1003) an amount of money sufficient to pay the Redemption Price of, and (except if the Redemption Date shall be an Interest Payment Date) accrued interest on, all the Securities which are to be redeemed on that date other
than any Securities called for redemption on that date which have been converted prior to the date of such deposit. 
 If any
Security called for redemption is converted, any money deposited with the Trustee or with any Paying Agent or so segregated and held in trust for the redemption of such Security shall (subject to any right of the Holder of such Security or any
Predecessor Security to receive interest as provided in the last paragraph of Section 306) be paid to the Company upon Company Request or, if then held by the Company, shall be discharged from such trust. 

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, 

  
 72 

 
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 Trustee duly executed by the Holder thereof or his attorney duly authorized in writing), and the Company shall execute, and 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. 
 ARTICLE TWELVE 

LEGAL DEFEASANCE AND COVENANT DEFEASANCE 
 SECTION 1201. Applicability of Article; Company’s Option to Effect Legal Defeasance or Covenant Defeasance. 
 If pursuant to Section 303 provision is made for either or both of (a) legal defeasance of the Securities of a series under Section 1202 or (b) covenant defeasance of the Securities of
a series under Section 1203 to apply to Securities of any series, then the provisions of such Section or Sections, as the case may be, together with the other provisions of this Article Twelve, shall be applicable to the Securities of such
series, and the Company may at its option, at any time, with respect to the Securities of such series, elect to have either Section 1202 (if applicable) or Section 1203 (if applicable) be applied to the Outstanding Securities of such
series upon compliance with the conditions set forth below in Section 1204. 

  
 73 

 SECTION 1202. Legal Defeasance and Discharge. 

Upon the Company’s exercise of the above option applicable to this Section 1202, the Company shall be deemed to have been
discharged from its obligations with respect to the Outstanding Securities of such series on the date the conditions set forth below are satisfied (hereinafter, “legal defeasance”). 

For this purpose, such legal defeasance means that the Company shall be deemed to have paid and discharged the entire indebtedness
represented by the Outstanding Securities of such series and to have satisfied all its other obligations under such Securities and this Indenture insofar as such Securities are concerned (and the Trustee, at the expense of the Company, shall execute
proper instruments acknowledging the same), except for the following which shall survive until otherwise terminated or discharged hereunder: 
 (a) the rights of Holders of Outstanding Securities of such series to receive, solely from the trust fund described in Section 1204 and as more fully set forth in such Section, payments in respect of
the principal of and interest on and Additional Amounts, if any, with respect to, such Securities when such payments are due; 
 (b) the Company’s obligations with respect to such Securities under Sections 304, 305, 607, 1002, 1003 and 1009 (but only to the extent that any Additional Amounts payable exceed the amount deposited
in respect of such Additional Amounts pursuant to Section 1204); 
 (c) the rights, powers, trusts, duties
and immunities and other provisions in respect of the Trustee hereunder; and 
 (d) this Article Twelve.

 Subject to compliance with this Article Twelve, the Company may exercise its option under this Section 1202 notwithstanding the prior
exercise of its option under Section 1203 with respect to the Securities of such series. 
 SECTION 1203. Covenant Defeasance.

 Upon the Company’s exercise of the above option applicable to this Section 1203, the Company shall be released from
its obligations under Sections 801, 1004, 1102, 501(3) (as to Sections 801 and 1004), 501(6) and 501(7) with respect to the Outstanding Securities of such series on and after the date the conditions set forth below are satisfied
(hereinafter, “covenant defeasance”). 

  
 74 

 For this purpose, such covenant defeasance means that, with respect to the Outstanding
Securities of such series, the Company may omit to comply with and shall have no liability in respect of any term, condition or limitation set forth in any such Section, whether directly or indirectly by reason of any reference elsewhere herein to
any such Section or by reason of any reference in any such Section to any other provision herein or in any other document, but the remainder of this Indenture and such Securities shall be unaffected thereby. Following a covenant defeasance, payment
of the Securities of such series may not be accelerated because of an Event of Default specified above in this Section 1203. 
 SECTION
1204. Conditions to Defeasance or Covenant Defeasance. 
 The following shall be the conditions to application of either
Section 1202 or Section 1203 to the Outstanding Securities of such series. 
 (a) The Company shall
irrevocably have deposited or caused to be deposited with the Trustee (or another trustee satisfying the requirements of Section 609 who shall agree to comply with the provisions of this Article Twelve applicable to it) as trust funds in trust
for the purpose of making the following payments, specifically pledged as security for, and dedicated solely to, the benefit of the Holders of such Securities, (A) an amount in the Security Currency, or (B) Government Securities which
through the scheduled payment of principal and interest in respect thereof in accordance with their terms will provide, within two weeks of the due date of any payment, money in an amount, or (C) a combination thereof, sufficient, in the
opinion of a nationally recognized firm of independent public accountants expressed in a written certification thereof delivered to the Trustee, to pay and discharge, and which shall be applied by the Trustee (or other qualifying trustee) to pay and
discharge, the principal of and each installment of interest on the Outstanding Securities of such series on the Stated Maturity of such principal or interest in accordance with the terms of this Indenture and of such Securities. Before such a
deposit, the Company may make arrangements satisfactory to the Trustee for the redemption of any series of Securities at a future date in accordance with any redemption provisions relating to such series, which shall be given effect in applying the
foregoing. 
 (b) No event which is, or which with notice or lapse of time or both would become, an Event of
Default with respect to the Securities of such series shall have occurred and be continuing on the date of such deposit. 
 (c) Such legal defeasance or covenant defeasance shall not cause the Trustee for the Securities of such series to have a conflicting interest for purposes of the Trust Indenture Act with respect to any
Securities of the Company. 
 (d) Such legal defeasance or covenant defeasance shall not result in a breach or
violation of, or constitute a default under, this Indenture or any other agreement or instrument to which the Company is a party or by which it is bound. 
 (e) Such legal defeasance or covenant defeasance shall not cause any Securities of such series then listed on any registered national securities exchange under the Exchange Act to be deleted. 

  
 75 

 (f) In the case of an election under Section 1202, the Company shall
have delivered to the Trustee an Opinion of Counsel stating that (i) the Company has received from, or there has been published by, the Internal Revenue Service a ruling, or (ii) since the date of this Indenture there has been a change in
the applicable federal income tax law, in either case to the effect that, and based thereon such opinion shall confirm that, the Holders of the Outstanding Securities of such series will not recognize income, gain or loss for federal income tax
purposes as a result of such legal defeasance and will be subject to federal income tax on the same amounts, in the same manner and at the same times as would have been the case if such legal defeasance had not occurred. 

(g) In the case of an election under Section 1203, the Company shall have delivered to the Trustee an Opinion of
Counsel to the effect that the Holders of the Outstanding Securities of such series will not recognize income, gain or loss for federal income tax purposes as a result of such covenant defeasance and will be subject to federal income tax on the same
amounts, in the same manner and at the same times as would have been the case if such covenant defeasance had not occurred. 
 (h) Such legal defeasance or covenant defeasance shall be effected in compliance with any additional terms, conditions or limitations which may be imposed on the Company in connection therewith pursuant
to Section 301. 
 (i) The Company shall have delivered to the Trustee an Officer’s Certificate or an
Opinion of Counsel, stating that all conditions precedent provided for in the Indenture relating to either the legal defeasance under Section 1202 or the covenant defeasance under or Section 1203 (as the case may be) have been complied
with. 
 SECTION 1205. Deposited Money and Government Securities to be Held in Trust; Other Miscellaneous Provisions. 

Subject to the provisions of the last two paragraphs of Section 1003, all money and Government Securities (including the proceeds
thereof) deposited with the Trustee (or other qualifying trustee, collectively, for purposes of this Section 1205, the “Trustee”) pursuant to Section 1204 in respect of the Outstanding Securities of such series shall be held in
trust and applied by the Trustee, in accordance with the provisions of such Securities and this Indenture, to the payment, either directly or through any Paying Agent (but not including the Company acting as its own Paying Agent) as the Trustee may
determine, to the Holders of such Securities, of all sums due and to become due thereon in respect of principal and interest and Additional Amounts, if any, but such money need not be segregated from other funds except to the extent required by law.

 The Company shall pay and indemnify the Trustee against any tax, fee or other charge imposed on or assessed against the
Government Securities deposited pursuant to Section 1204 or the principal and interest received in respect thereof other than any such tax, fee or other charge which by law is for the account of the Holders of the Outstanding Securities of such
series. 

  
 76 

 Anything in this Article Twelve to the contrary notwithstanding, the Trustee shall deliver
or pay to the Company from time to time upon Company Request any money or Government Securities held by it as provided in Section 1204 which, in the opinion of a nationally recognized firm of independent public accountants expressed in a
written certification thereof delivered to the Trustee, are in excess of the amount thereof which would then be required to be deposited to effect an equivalent defeasance or covenant defeasance. 

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 Sections 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.

provisions of the Base Indenture, and thereafter “Depositary” shall mean such successor Depositary;

extent applicable to such transaction and as in effect from time to time. 
 (g) the following terms have, with
respect to the Notes (but not with respect to any other series of Securities), the meanings given to them in this Section 102 (g):

 “Rate Calculation Date” means the second Mexican FX Day immediately preceding an Interest Payment
Date, Redemption Date, Stated Maturity or other Maturity, as applicable. Notwithstanding the preceding sentence, if the Rate Calculation Date is not a Business Day, then the Rate Calculation Date will be the immediately preceding Mexican FX Day

the event that the FIX FX Rate is not so available by 3:00 p.m. (Mexico City time) on any Rate Calculation Date, then the Settlement Rate for such Rate Calculation Date will be determined by the Calculation Agent by taking the arithmetic mean (such
mean, the “Alternative Rate”) of the Peso/Dollar exchange rate for the foreign exchange market in Mexico for transactions payable in 48 hours offered at or about such time on such date by (i) Banco Nacional de México, S.A.,
Institución de Banca Múltiple, Integrante del Grupo Financiero Banamex, (ii) Banco Inbursa, S.A., Institución de Banca Múltiple, Grupo Financiero Inbursa, (iii) Bank of America Global FX, (iv) Banco Credit

Banks”); provided, however, that if any of the Reference Banks ceases to offer such an exchange rate, then, for the purpose of determining the Alternative Rate, the Company shall timely select a leading bank or financial institution as a
replacement Reference Bank. In the event that the Calculation Agent determines (in its sole and absolute discretion) that neither the FIX FX Rate nor the Alternative Rate can be ascertained on a Rate Calculation Date in accordance with the
foregoing, the Company shall determine the Settlement Rate (and method of determining the Settlement Rate) in respect of such date in its sole and absolute discretion, taking into consideration all available information that in good faith it deems
relevant. 
 ARTICLE TWO 
 GENERAL TERMS AND CONDITIONS OF THE NOTES 

Section 201. Designation and Principal Amount.  
 There is hereby authorized and established a series of securities designated the 8.75% Senior Notes due 2016 (the “Notes”), in an aggregate principal amount of Ps.4,500,000,000 (which amount
does not include Notes authenticated and delivered upon registration of transfer of, or in exchange for, or in lieu of, other securities of such series pursuant to Sections 304, 305, 906 or 1105 of the Base Indenture), which amount shall be
specified in the Company Order for the authentication and delivery of Notes pursuant to Section 303 of the Base Indenture. The principal of the Notes shall be due and payable at their Stated Maturity. 

The Company may, from time to time and without the consent of the Holders, issue additional notes on terms and conditions identical to
those of the Notes, which additional notes shall increase the aggregate principal amount of, and shall be consolidated and form a single series with, the Notes. 

  
 4 

 The Notes shall be known and designated as the “8.75% Senior Notes due 2016” of
the Company. The Stated Maturity of the Notes shall be January 31, 2016 and they shall bear interest at the rate of 8.75% per annum, from January 31, 2006 or from the most recent Interest Payment Date (or, in the case that
Section 202 hereof is applicable, the subsequent Business Day) to which interest has been paid or duly provided for, as the case may be, payable semi-annually on January 31 and July 31 of each year, commencing July 31, 2006,
until the principal thereof is paid or made available for payment; provided, however, that any amount of interest on any Note which is overdue shall bear interest (to the extent that payment thereof shall be legally enforceable) at the rate
per annum then borne by such Note from the date such amount is due to the day it is paid or made available for payment, and such overdue interest shall be paid as provided in Section 306 of the Base Indenture. 

Section 202. Legal Holidays.  
 Section 114 of the Base Indenture is hereby amended and restated with respect to the Notes (but not with respect to any other series of Securities) as follows: 

“In any case where any Interest Payment Date, Redemption Date, Stated Maturity or other Maturity of the Notes shall not be a
Business Day, then (notwithstanding any other provision of this Indenture or the Notes) payment of interest, principal or Additional Amounts will not be made on such date, but will be made on the next succeeding Business Day with the same force and
effect as if made on the Interest Payment Date, Redemption Date, Stated Maturity or other Maturity, as the case may be; provided that interest will accrue on the principal of the Notes at the applicable interest rate from the original
Interest Payment Date, Redemption Date, Stated Maturity or other Maturity, as the case may be, to (but excluding) that next Business Day.” 

Section 203. Denominations.  
 Section 302 of the Base Indenture is hereby amended and restated with respect to the Notes (but not with respect to any other series of Securities) as follows: 

“The Notes shall be issued only in denominations of Ps.1,000,000 and integral multiples of Ps.100,000 in excess thereof.”

 Section 204. Computation of Interest.  
 Section 309 of the Base Indenture is hereby amended and restated with respect to the Notes (but not with respect to any other series of Securities) as follows: 

“Interest on the Notes shall be computed on the basis of the actual number of days during the relevant interest period and a 360-day
year.” 

  
 5 

 Section 205. ISIN Numbers.  

Section 310 of the Base Indenture is hereby amended and restated with respect to the Notes (but not with respect to any other series
of Securities) as follows: 
 “The Company in issuing the Notes may use an “ISIN” number, and, if
so, the Trustee shall use an “ISIN” number 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 number either as printed on the
Notes or as contained in any notice of a redemption and that reliance may be placed only on the other identification numbers printed on the Notes, and any such redemption shall not be affected by any defect in or omission of such number. The Company
shall promptly notify the Trustee in writing of any change in the “ISIN” number. The Company may also use a “Common Code” number.” 
 Additionally, clause (1) of Section 301 of the Base Indenture is hereby amended and restated with respect to the Notes (but not with respect to any other series of Securities) as “(1) the
title of the Securities, including “ISIN” numbers, of the series, which shall distinguish the Securities of the series from Securities of any other series”; and clause (6) of Section 1102 of the Base Indenture is hereby
amended and restated with respect to the Notes (but not with respect to any other series of Securities) as “(6) applicable “ISIN” number.” 
 Section 206. Registration of Transfer and Exchange.  
 Clause
(2) of Section 304 of the Base Indenture is hereby amended and restated with respect to the Notes (but not with respect to any other series of Securities) as follows: 

“(2) Notwithstanding any other provision in this Indenture or the Notes, no Global Notes may be exchanged in whole or
in part for Notes registered, and no transfer of a Global Note 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 has notified the Company that it is
unwilling or unable to continue as Depositary for such Global Note 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 Note 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 Note exchanged pursuant to Clause (A) above shall be so exchanged in whole and not in part and any Global Note exchanged pursuant to Clause (B) or (C) above may be exchanged in whole or from time to time in part as
directed by the Depositary. Any Note issued in exchange for a Global Note or any portion thereof shall be a Global Note, provided that any such Note so issued that is registered in the name of a Person other than the Depositary or a nominee
thereof shall not be a Global Note.” 

  
 6 

 Clause (5) of Section 304 of the Base Indenture is hereby amended and restated
with respect to the Notes (but not with respect to any other series of Securities) as follows: 
 “(5)
Neither any members of, or participants in, (“Agent Members”) Clearstream Banking, Société Anonyme (“Clearstream, Luxembourg”) or Euroclear Bank S.A./N.V. (“Euroclear”) shall have any rights under this
Indenture with respect to any Global Note, or under any Global Note, 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 Note 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, Clearstream, Luxembourg, Euroclear, their respective Agent Members and any other person on whose behalf an Agent Member may act, the
operation of customary practices of such Persons governing the exercise of the rights of a holder of any Note.” 
 Section 207.
Payment Currency.  
 Payment of principal, interest, Additional Amounts and any other amounts due in respect of the Notes
shall be made, except as provided below, in Dollars, in amounts determined by the Calculation Agent by translating the corresponding Peso amounts into Dollars at the Settlement Rate on the Rate Calculation Date applicable to the relevant Interest
Payment Date, Redemption Date, Stated Maturity or other Maturity or payment date for Defaulted Interest pursuant to Section 306 of the Base Indenture. 
 Holders of the Notes may elect to receive payment of principal, interest, Additional Amounts and any other amounts due in respect of the Notes in Pesos. Holders who wish to elect to receive a particular
payment of principal, interest, Additional Amount and any other amounts due in respect of the Notes in Pesos must notify the principal Paying Agent (initially, the Trustee) no later than the
8th day preceding the applicable Interest Payment Date,
Redemption Date, Stated Maturity or other Maturity (but not earlier than the applicable Regular Record Date or Special Record Date). Any notice referred to in this paragraph must be delivered in accordance with the provisions of Section 105 of
the Base Indenture for notices by Holders to the Trustee or, if the Holder is a common depositary (or nominee) for Clearstream, Luxembourg and Euroclear, pursuant to a “swift message” or similar communication. The principal Paying Agent
shall notify the Company, the Trustee and any other Paying Agent of any elections by Holders to receive payment in Pesos (including the amounts so selected) as soon as reasonably practicable (and in no case later than 24 hours) after receipt thereof
as set forth above. 

  
 7 

 Clause (1) of Section 306 of the Base Indenture is hereby amended and restated
with respect to the Notes (but not with respect to any other series of Securities) as follows: 
 “(1) The
Company may elect to make payment of any Defaulted Interest to the Persons in whose names the Notes (or their respective Predecessor Notes) are registered at the close of business on a Special Record Date for the payment of such Defaulted Interest,
which shall be fixed in the following manner. The Company shall notify the Trustee in writing of the amount of Defaulted Interest proposed to be paid on each Note and the date of the proposed payment, and at the same time the Company shall make
arrangements satisfactory to the Trustee for the deposit with the Trustee of an amount of money equal to the aggregate amount proposed to be paid in respect of such Defaulted Interest prior to the time of the proposed payment, such money when
deposited to be held in trust for the benefit of the Persons entitled to such Defaulted Interest as in this Clause provided. Thereupon the Trustee shall fix a Special Record Date for the payment of such Defaulted Interest which shall be not more
than 20 days and not less than 15 days prior to the date of the proposed payment and not less than 15 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 Security Register, not less than 15 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).” 
 Section 208. Forms Generally.  

The Notes shall be in substantially the forms set forth in this Section 208, with such appropriate insertions, omissions,
substitutions and other variations as are required or permitted by this Fourth Supplemental Indenture, and may have such letters, numbers or other marks of identification and such legends or endorsements placed thereon as may be required to comply
with the rules of any securities exchange or as may, consistently herewith, be determined by the officers executing such Notes, as evidenced by their execution thereof.

 Upon their original issuance, the Notes shall be issued in the form of one or more Global
Notes in definitive, fully registered form without coupons, substantially in the form set forth in this Section 208, with such applicable legends as provided herein. Such Global Notes shall be registered in the name of the Depositary, or its
nominee, and deposited with the Trustee, at its Corporate Trust Office, as custodian for the Depositary, duly executed by the Company and authenticated by the Trustee as hereinafter provided. The aggregate amount of any Global Notes may from time to
time be increased or decreased by adjustments made on the records of the Trustee, as custodian for the Depositary, as provided in Section 206 hereof.

organized and existing under the laws of the United Mexican States (“Mexico”) (herein called the “Company”, which term includes any successor Person under the Indenture, as amended, supplemented and otherwise modified by the
Fourth Supplemental Indenture hereinafter referred to), for value received, hereby promises to pay to                     , or registered assigns,

taken together with the principal amounts of all other Outstanding Notes, shall initially equal Ps.4,500,000,000 in the aggregate, provided, however, that the Company may from time to time or at any time, without the consent of the Holders of
the Notes, issue additional notes with terms and conditions identical to those of the Notes, which additional notes shall increase the aggregate principal amount of, and shall be consolidated and form a single series with, the Notes) as may be set
forth in the records of the Trustee hereinafter referred to in accordance with the Indenture, as amended, supplemented and otherwise modified by the Fourth Supplemental Indenture,] on January 31, 2016 (unless earlier redeemed, in which case, on

July 31 in each year, commencing July 31, 2006 at the rate of 8.75% per annum, until the principal hereof is paid or made available for payment, provided, however, that any amount of interest on this Note which is overdue shall
bear interest (to the extent that payment thereof shall be legally enforceable) at the rate per annum then borne by this Note from the date such amount is due to but not including the day it is paid or made available for payment, and such overdue
interest shall be paid as provided in Section 306 of the Indenture. 
 Payment of principal, interest, Additional Amounts
and any other amounts due in respect of the Notes shall be made in Dollars or, subject to certain conditions as set forth in the reverse hereof, Pesos.

 The interest so payable, and punctually paid or duly provided for, on any Interest Payment
Date will, as provided in such Indenture and Fourth Supplemental Indenture, be paid to the Person in whose name this Note (or one or more Predecessor Notes) is registered at the close of business on the Regular Record Date for such interest, which
shall be January 16 or July 16 (whether or not a Business Day), as the case may be, next preceding such Interest Payment Date. Any such interest not so punctually paid or duly provided for will forthwith cease to be payable to the Holder
on the relevant Regular Record Date and may either be paid to the Person in whose name this Note (or one or more Predecessor Notes) is registered at the close of business on a Special Record Date for the payment of such Defaulted Interest to be
fixed by the Trustee, notice whereof shall be given to Holders of the Notes not less than 15 days prior to such Special Record Date, or be paid at any time in any other lawful manner not inconsistent with the requirements of any securities exchange
on which the Note may be listed, and upon such notice as may be required by such exchange, all as more fully provided in the Indenture or Fourth Supplemental Indenture. Interest on this Note shall be computed on the basis set forth in the Indenture

Trustee or agency of the Company in the Borough of Manhattan, the City of New York, New York, maintained for such purpose and at any other office or agency maintained by the Company for such purpose, in such coin or currency of the United States of
America as at the time of payment is legal tender for payment of public and private debts against surrender of this Note in the case of any payment due at the Maturity of the principal thereof (other than any payment of interest that first becomes
payable on a day other than an Interest Payment Date); provided, however, that at the option of the Company payment of interest may be made by check mailed to the address of the Person entitled thereto as such address shall appear in the
Securities Register; provided, further, that all payments of the principal of and interest on this Note, the Permitted Holders of which have given wire transfer instructions to the Trustee, the Company, or its agent at least 8 Business Days
prior to the applicable payment date, will be required to be made by wire transfer of immediately available funds to the accounts specified by such Permitted Holders in such instructions. [if the Note is a Global Note, then insert —

 (b) Form of Reverse of Note. 

This Note is a duly authorized issue of securities of the Company (herein called the “Notes”), issued under an Indenture, dated
as of November 19, 2003, as amended, supplemented and otherwise modified by the Second Supplemental Indenture dated as of January 27, 2005 (herein called the “Indenture”, which term shall have the meaning assigned to it in such
instrument), as amended, supplemented and otherwise modified by a Fourth Supplemental Indenture dated as of January 31, 2006 (herein called the “Fourth Supplemental Indenture”), between the Company and JPMorgan Chase Bank, N.A., as
Trustee (herein called the “Trustee”, which term includes any successor trustee under the Indenture), and reference is hereby made to the Indenture, as amended, supplemented and otherwise modified by the Fourth Supplemental 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 Notes and of the terms upon which the Notes are, and are to be, authenticated and delivered. This Note
is one of the series designated on the face hereof. 
 Additional notes on terms and conditions identical to those of this Note
may be issued by the Company without the consent of the Holders of the Notes. The amount evidenced by such additional Notes shall increase the aggregate principal amount of, and shall be consolidated and form a single series with, the Notes.

 In any case where any Interest Payment Date, Redemption Date, Stated Maturity or other Maturity of the Notes shall not be a
Business Day, then (notwithstanding any other provision of this Indenture or the Notes) payment of interest, principal or 

  
 12 

 
Additional Amounts will not be made on such date, but will be made on the next succeeding Business Day with the same force and effect as if made on the Interest Payment Date, Redemption Date,
Stated Maturity or other Maturity, as the case may be; provided that interest will accrue on the principal of the Notes at the applicable interest rate from the original Interest Payment Date, Redemption Date, Stated Maturity or other
Maturity, as the case may be, to (but excluding) that next Business Day. 
 Each payment of principal, interest or Additional
Amounts and any other amounts due in respect of the Notes will be made, except as provided below, in Dollars, in the amount determined by the Calculation Agent by translating the applicable Peso amount of such payment into Dollars at the Settlement
Rate as in effect on the Rate Calculation Date applicable to the relevant Interest Payment Date, Redemption Date, Stated Maturity or other Maturity or payment date for Defaulted Interest pursuant to Section 306 of the Base Indenture.

 For the purposes of translating Peso amounts into Dollars: 

“Mexican FX Day” means each Monday, Tuesday, Wednesday, Thursday and Friday that is (i) not a day on which
banking institutions or foreign exchange markets in Mexico City generally are authorized or obligated by law, regulation or executive order to close and (ii) a day on which banking institutions and foreign exchange markets in Mexico City are
open for business with the general public. 
 “Rate Calculation Date” means the second Mexican FX Day
immediately preceding an Interest Payment Date, Redemption Date, Stated Maturity or other Maturity, as applicable. Notwithstanding the preceding sentence, if the Rate Calculation Date is not a Business Day, then the Rate Calculation Date will be the
immediately preceding Mexican FX Day (i.e., prior to such second Mexican FX Day) that is a Business Day. 

“Settlement Rate” means the Peso/Dollar exchange rate (the “FIX FX Rate”) reported by the Central Bank
of Mexico on its website (which, as of the date of the original execution of the Fourth Supplemental Indenture, is located at http://www.banxico.gob.mx) on the applicable Rate Calculation Date as the average of quotes in the wholesale foreign
exchange market in Mexico for transactions payable within 48 hours. In the event that the FIX FX Rate is not so available by 3:00 p.m. (Mexico City time) on any Rate Calculation Date, then the Settlement Rate for such Rate Calculation Date will be
determined by the Calculation Agent by taking the arithmetic mean (such mean, the “Alternative Rate”) of the Peso/Dollar exchange rate for the foreign exchange market in Mexico for transactions payable in 48 hours offered at or about such
time on such date by (i) Banco Nacional de México, S.A., Institución de Banca Múltiple, Integrante del Grupo Financiero Banamex, (ii) Banco Inbursa, S.A., Institución de 

  
 13 

 Banca Múltiple, Grupo Financiero Inbursa, (iii) Bank of America Global FX,
(iv) Banco Credit Suisse (México) S.A., Institución de Banca Múltiple, Grupo Financiero Credit Suisse (México), and (v) JPMorgan Chase Bank, N.A. (such banks, together with their respective successors, the
“Reference Banks”); provided, however, that if any of the Reference Banks ceases to offer such an exchange rate, then, for the purpose of determining the Alternative Rate, the Company shall timely select a leading bank or financial
institution as a replacement Reference Bank. In the event that the Calculation Agent determines (in its sole and absolute discretion) that neither the FIX FX Rate nor the Alternative Rate can be ascertained on a Rate Calculation Date in accordance
with the foregoing, the Company shall determine the Settlement Rate (and method of determining the Settlement Rate) in respect of such date in its sole and absolute discretion, taking into consideration all available information that in good faith
it deems relevant. 
 Holders of the Notes may elect to receive any payment of principal, interest, Additional Amounts and any
other amounts due in respect of the Notes in Pesos. In order to receive a particular payment in Pesos, the Holder must notify the Trustee no later than the eighth day preceding the applicable Interest Payment Date, Redemption Date, Stated Maturity
or other Maturity or payment date for Defaulted Interest pursuant to Section 306 of the Base Indenture for such payment (but not earlier than the applicable Regular Record Date or Special Record Date). A separate notice of such election in
accordance with the foregoing procedures must be made with respect to each payment for which a payment denominated in Pesos is elected. Holders who own beneficial interests in the Global Note through accounts with Clearstream, Luxembourg or
Euroclear must arrange to have such notice given on their behalf. 
 So long as any Notes are outstanding, the Company shall
maintain a calculation agent for determining the Settlement Rate on each Rate Calculation Date. The Company has initially appointed the Calculation Agent to serve as such. Each determination of the Calculation Agent will, in the absence of manifest
error, be conclusive for all purposes and binding on the Company and the Holders of the Notes. 
 In the event of redemption of
this Note in part only, a new Note of this series and of like tenor for the unredeemed portion hereof will be issued in the name of the Holder hereof upon the cancellation hereof. 

If an Event of Default with respect to Notes shall occur and be continuing, the principal of all of the Notes may be declared due and
payable in the manner and with the effect provided in the Indenture, as amended, supplemented and otherwise modified by the Fourth Supplemental Indenture. 
 All payments of principal and interest in respect of the Notes shall be made after withholding or deduction for any present or future taxes, duties, assessments or

  
 14 

 
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 Notes 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 Note to the extent: 
 (i) that any such taxes, duties, assessments or other governmental charges
would not have been imposed but for (A) a connection between the Holder and Mexico other than the ownership or holding of such Note and the mere receipt of payments with respect to such Note 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 between Mexico and the Holder or any beneficial owner of such Note, if compliance is required by law,
regulation or by an applicable income tax treaty to which Mexico is a party and which is in effect, 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 or reporting requirement is required to the effect that Holders will be required to provide such information and identification;

 (ii) of any such taxes, duties, assessments or other governmental charges with respect to a Note 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
Note would have been entitled to such Additional Amounts on presenting such Note for payment on any date during such 15-day period; 
 (iii) of estate, inheritance, gift or other similar taxes, assessments, or other governmental charges imposed with respect to a Note; 

(iv) any tax, duty, assessment or other governmental charge payable otherwise than by deduction or withholding from
payments on any series of Notes; and 
 (v) any payment on a Note to a Holder who 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 Note. 

  
 15 

 For purposes of the provisions described in Clause (i) above, the term “Holder” of any Note
means the direct nominee of any beneficial owner of such Note, which holds such beneficial owner’s interest in such Note. 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 Note (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), regulation (including proposed regulations) and administrative practice or (b) Rule 3.23.8 is in effect, unless the provision of the information, documentation or other evidence described in
such Clause (i)(B) is expressly required by statute, regulation, rule or administrative practice in order to apply Rule 3.23.8, and the Company cannot obtain such information, documentation or other evidence on its own through reasonable diligence
and the Company otherwise would meet the requirements for application of Rule 3.23.8. In addition, such Clause (i)(B) shall not be construed 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. [If the Note is a Global Note, then insert — Persons who hold a
beneficial interest in the Global Note through S.D. Indeval, S.A. de C.V., Institución para el Depósito de Valores (“Indeval”) may be required to certify as to their residency in accordance with procedures established
by Indeval.] 
 At the request of the Trustee, the Company shall provide the Trustee with documentation (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
Notes or the Paying Agent, as applicable, upon written request therefor. 
 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,
the Fourth Supplemental Indenture or the issuance of the Notes. 
 All references herein, in the Indenture or in the Fourth
Supplemental Indenture, to principal, premium, interest or any other amount payable in respect of any Note shall be deemed to include all Additional Amounts, if any, payable in respect of such principal,

  
 16 

 
premium, interest or any 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. 
 In the event
that Additional Amounts actually paid with respect to the Notes 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 Notes, 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 Additional Amounts, 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, the Fourth
Supplemental Indenture and the Notes to principal in respect of any Note shall be deemed to mean and include any Redemption Price or Repurchase Price payable in respect of such Note pursuant to any redemption or repurchase right hereunder (and all
such references to the Stated Maturity of the principal in respect of any Note shall be deemed to mean and include the Redemption Date with respect to any such Redemption Price and the Repurchase Date with respect to any such Repurchase 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 1010 of the Indenture. 

In the event of any Change in Control occurring prior to the Stated Maturity, each Holder of Notes will have the right, at the
Holder’s option, to require the Company to repurchase all or any portion (provided that such portion is Ps.100,000 or an integral multiple thereof) of the principal amount of the Holder’s notes on the date that is 60 days after the
date the Company provides notice of the Change in Control, at a cash price equal to the sum of: (i) 100% of the principal amount of, and any premium on, the Notes being repurchased, (ii) accrued and unpaid current interest thereon to but
not including the Holder Repurchase Date and (iii) any Additional Amounts that would otherwise be payable. 
 The
Indenture, as amended, supplemented and otherwise modified by the Fourth Supplemental Indenture, permits, with certain exceptions as therein provided, the amendment thereof and the modification of the rights and obligations of the Company and the
rights of the Holders of the Notes of each series to be affected under the Indenture, as amended, supplemented and otherwise modified by the Fourth Supplemental Indenture, at any time by the Company and the Trustee with the consent of the Holders of
a majority in principal amount of the Notes at the time Outstanding all series to be affected (considered together as one class for this purpose). The Indenture 

  
 17 

 
also contains provisions (i) permitting the Holders of a majority in principal amount of the Notes at the time Outstanding of all series to be affected under the Indenture as supplemented
(considered together as one class for this purpose), on behalf of the Holders of all Notes of such series, to waive compliance by the Company with certain provisions of the Indenture as amended, supplemented and otherwise modified by the Fourth
Supplemental Indenture and (ii) permitting the Holders of a majority in principal amount of the Notes at the time Outstanding of any series to be affected under the Indenture as supplemented (with each such series considered separately for this
purpose), on behalf of the Holders of all Notes of such series, to waive certain past defaults under the Indenture as amended, supplemented and otherwise modified by the Fourth Supplemental Indenture and their consequences. Any such consent or
waiver by the Holder of this Note shall be conclusive and binding upon such Holder and upon all future Holders of this Note and of any Note issued upon the registration of transfer hereof or in exchange herefor or in lieu hereof, whether or not
notation of such consent or waiver is made upon this Note. 
 As provided in and subject to the provisions of the Indenture, as
amended, supplemented and otherwise modified by the Fourth Supplemental Indenture, the Holder of this Note shall not have the right to institute any proceeding with respect to the Indenture, the Fourth Supplemental 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 Notes, the Holders of not less than 25% in principal amount
of the Notes 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 reasonably satisfactory to it, and the Trustee shall not
have received from the Holders of a majority in principal amount of Notes 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. The foregoing shall not apply to any suit instituted by the Holder of this Note for the enforcement of any payment of principal hereof or any interest hereon on or after the respective due dates expressed herein. 

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

 As provided in the Indenture and the Fourth Supplemental Indenture and subject to certain limitations therein set forth, the
transfer of this Note is registrable in the Security Register, upon surrender of this Note for registration of transfer at the office of the Trustee or agency of the Company in any place where the principal of and any interest on this Note are
payable, duly endorsed by, or accompanied by a written instrument of transfer in form satisfactory to the Company and the Security Registrar 

  
 18 

 
duly executed by, the Holder hereof or his attorney duly authorized in writing, and thereupon one or more new Notes of this series and of like tenor, of authorized denominations and for the same
aggregate principal amount, will be issued to the designated transferee or transferees. 
 The Notes are issuable only in
registered form without coupons in denominations of Ps.1,000,000 and any integral multiple of Ps.100,000 in excess thereof. As provided in the Indenture, as amended, supplemented and otherwise modified by the Fourth Supplemental Indenture, and
subject to certain limitations therein set forth, Notes are exchangeable for a like aggregate principal amount of Notes 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 may require payment of a sum
sufficient to cover any tax or other governmental charge payable in connection therewith.
