 (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 (herein called the “Indenture”, which term shall have the meaning assigned to it in such instrument), as amended,
supplemented and otherwise modified by a Second Supplemental Indenture dated as of January 27, 2005 (herein called the “Second 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 Second 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 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 

  

 -12- 

 
the Indenture, as amended, supplemented and otherwise modified by the Second 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 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 holding of such Note and the receipt of
payments with respect to such Note or (B) failure by the Holder to comply with any certification, identification or other reporting requirement concerning the nationality, residence, identity or connection between Mexico and the Holder, 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 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 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; 
  
 (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. 
  

 -13- 

 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) above shall not apply if (a) the provision of information, documentation or other evidence described in such Clause (i) 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 3.25.15 is in effect, unless the provision of the information, documentation or other evidence described in such Clause
(i) is expressly required by statute, regulation, rule or administrative practice in order to apply Rule 3.25.15, 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 3.25.15. In addition, such Clause (i) 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. 
  
 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 Second Supplemental Indenture or the issuance of the Notes. 
  
 All references herein, in the Indenture or in the Second Supplemental Indenture, to principal, premium or interest in respect of any Note shall be deemed to include all Additional Amounts, if any, payable in respect
of such principal, premium or interest, 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 paragraph 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 Notes, 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 

  

 -14- 

 
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 Second
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. 
  
 The Notes are subject to redemption upon not less than 30 nor more than 60
days’ notice by mail, at any time: 
  
 (i)
as a whole but not in part, at the election of the Company, at a cash price equal to the sum of (A) the principal amount of the Notes being redeemed, (B) accrued and unpaid current interest thereon to but not including the date fixed for redemption,
and (C) any Additional Amounts which would otherwise be payable up to but not including the date fixed for redemption, if, as a result of any amendment to, or change in, the laws (or any laws, 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, administration or application of such laws, rules, or regulations (including a holding by a court of
competent jurisdiction), which amendment or change of such laws, rules, or regulations becomes effective on or after the date of the Second Supplemental Indenture, 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 Notes were subject to withholding or deduction of Mexican Taxes at the rate of 10 percent; and 

 
 (ii) in whole or in part, at a Redemption Price equal to
the greater of (A) 100% of the principal amount of such Notes and (B) the sum of the present values of the remaining scheduled payments of principal and interest thereon (exclusive of interest accrued to the date of redemption) discounted to the
Redemption Date on a semiannual basis (assuming a 360-day year consisting of twelve 30-day months) at, in each case, the Treasury Rate plus 20 basis points, plus, in the case of (A) and (B), accrued interest on the principal amount of such Notes to
(but not including) the date of redemption. “Treasury Rate” means, with respect to any Redemption Date, the rate per annum equal to the semiannual equivalent yield to maturity or interpolated maturity (on a day count basis) of the
Comparable Treasury Issue, assuming a price for the Comparable Treasury Issue (expressed as a percentage of its principal amount) equal to the Comparable Treasury Price for such Redemption Date. “Comparable Treasury Issue” means the United
States Treasury security or securities selected by an Independent Investment Banker as having an actual or interpolated maturity comparable to the remaining term of the Notes to be redeemed that would be utilized, at the time of selection and in

  

 -15- 

 
accordance with customary financial practice, in pricing new issues of corporate debt securities of a comparable maturity to the remaining term of such
notes. “Independent Investment Banker” means one of the Reference Treasury Dealers appointed by the Company. “Comparable Treasury Price” means, with respect to any Redemption Date, (x) the average of the Reference Treasury Dealer
Quotations for such Redemption Date, after excluding the highest and lowest such Reference Treasury Dealer Quotation or (y) if the Trustee obtains fewer than four such Reference Treasury Dealer Quotations, the average of all such quotations.
“Reference Treasury Dealer” means each of Credit Suisse First Boston LLC and J.P. Morgan Securities Inc. or their Affiliates which are primary United States government securities dealers, and their respective successors; provided, however,
that if any of the foregoing shall cease to be a primary United States government securities dealer in the City of New York (a “Primary Treasury Dealer”), the Company will substitute therefor another Primary Treasury Dealer.
“Reference Treasury Dealer Quotation” means, with respect to each Reference Treasury Dealer and any Redemption Date, the average, as determined by the Trustee, of the bid and asked prices for the Comparable Treasury Issue (expressed in
case as a percentage of its principal amount) quoted in writing to the Trustee by such Reference Treasury Dealer at 3:30 pm New York time on the third business day preceding such Redemption Date. 
  
 If a Change in Control occurs, the Holder of this Note, at the Holder’s
option, shall have the right, in accordance with the provisions of the Indenture, to require the Company to repurchase this Note (or any portion of the principal amount thereof that is equal to $1,000 or any integral multiple of $1,000 in excess
thereof) for cash at a Repurchase Price equal to the sum of (i) the principal amount of this Note being repurchased (ii) accrued and unpaid interest hereon to the Holder Repurchase Date, (iii) any original issue discount applicable to this Note and
(iv) any Additional Amounts which would otherwise be payable. 
  
 The Indenture, as amended, supplemented and otherwise modified by the Second 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 Second 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 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 Second 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 Second 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 

  

 -16- 

 
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 Second Supplemental Indenture, the Holder of this Note shall not have the right to institute any proceeding with respect to the Indenture, the Second
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 Second Supplemental Indenture and no provision of this Note or of the Indenture or the Second 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 Second Supplemental Indenture and subject to certain limitations therein set forth (including, without limitation,
the restrictions on transfer under Sections 302 and 303 of the Second Supplemental Indenture) 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 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 $100,000 and any integral multiple of $1,000 in excess thereof. As provided in the Indenture, as amended, supplemented and otherwise modified by the Second 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. 
  

 -17- 

 Prior to due presentment of this Note 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 Note is registered as the owner hereof for all purposes, whether or not this Note is overdue, and neither the Company, the Trustee nor any such agent shall be affected by
notice to the contrary.

 Section 303. Transfers and Exchanges 
  
 (a) Restricted Notes. Restricted Notes shall be subject to the restrictions on transfer (the “Transfer Restrictions”) provided in the
applicable legend(s) (the “Restrictive Legends”) required to be set forth on the face of each Restricted Note pursuant to Section 302 hereof, unless compliance with the Transfer Restrictions shall be waived by the Company in writing
delivered to the Trustee. 
  
 The Transfer Restrictions shall
cease and terminate with respect to any particular Restricted Note upon receipt by the Company of evidence satisfactory to it (which may include an opinion of independent counsel experienced in matters of United States federal securities law) that,
as of the date of determination, such Restricted Note (a) has been transferred by the Holder 

  

 -18- 

 
thereof pursuant to Rule 144, (b) has been sold pursuant to an effective registration statement under the Securities Act, or (c) has been transferred (i) in
a transaction satisfying all the requirements of Rule 903 or 904 (as applicable) of Regulation S or (ii) pursuant to Rule 144A, and receipt by the Trustee of an Officer’s Certificate certifying that the Company has received such evidence which
may include an opinion of counsel stating that the Transfer Restrictions have ceased and terminated with respect to such Note. All references in the preceding sentence to any regulation, rule or provision thereof shall be deemed also to refer to any
successor provisions thereof. In addition, the Company may terminate the Transfer Restrictions with respect to any particular Restricted Note in such other circumstances as it determines are appropriate for this purpose and shall deliver to the
Trustee an opinion of counsel, if any, and Officer’s Certificate certifying that the Transfer Restrictions have ceased and terminated with respect to such Note. 
  
 At the request of the Holder and upon the surrender of such Restricted Notes to the Trustee or Security Registrar for
exchange in accordance with the provisions of this Section 303, any Restricted Note as to which the Transfer Restrictions shall have terminated in accordance with the preceding paragraph shall be exchanged for a new Note of like aggregate principal
amount, but without the Restrictive Legends. Any Restricted Note as to which the Restrictive Legends shall have been removed pursuant to this paragraph (and any Note issued upon registration of transfer of, exchange for or in lieu of such Restricted
Note) shall thereupon cease to be a “Restricted Note” for all purposes of this Second Supplemental Indenture. 
  
 The Company shall notify the Trustee in writing of the effective date of any registration statement registering any Restricted Notes under the Securities
Act and shall ensure that any opinion of counsel received by it in connection with the removal of any Restrictive Legend is also addressed to the Trustee. The Trustee shall not be liable for any action taken or omitted to be taken by it in good
faith and without negligence on its part in accordance with such notice or any opinion of counsel. 
  
 As used in this Section 303(a), the term “transfer” encompasses any sale, pledge, transfer or other disposition of any Notes referred to herein.

  
 (b) Transfers Between Global Notes 
  
 (i) Restricted Global Note to Regulation S Global
Note. If the owner of a beneficial interest (an “Owner Transferor”) in a Restricted Global Note wishes at any time to transfer such beneficial interest to a Person (an “Owner Transferee”) who wishes to take delivery thereof
in the form of a beneficial interest in a Regulation S Global Note, such transfer may be effected, subject to the Applicable Procedures, only in accordance with the provisions of this Section 303(b)(i). Upon receipt by the Trustee, as Security
Registrar, at the Corporate Trust Office of (l) written instructions given in accordance with the Applicable Procedures from the Agent Member, whose account is to be debited (an “Agent Member Transferor”) with respect to the Restricted
Global Note, directing the Trustee, as Security Registrar, to credit or cause to be credited to a specified account of another Agent Member (an “Agent Member Transferee”) (which shall be an account with Euroclear or Clearstream or both) a
beneficial interest in a Regulation S Global Note in a principal amount equal to the beneficial interest in the Restricted Global Note to be so 

  

 -19- 

 
transferred (the “Restricted Global Transferred Amount”), (2) a written order given in accordance with the Applicable Procedures containing
information regarding the account of the Agent Member Transferee to be credited with, and the Agent Member Transferor to be debited by, the Restricted Global Transferred Amount, and (3) a certificate in substantially the form set forth in Annex A
given by the Owner Transferor, the Trustee, as Security Registrar, shall instruct the Depositary to reduce the principal amount of the Restricted Global Note, and to increase the principal amount of the Regulation S Global Note, by the Restricted
Global Transferred Amount, and to credit, or cause to be credited to, the account of the Agent Member Transferee a beneficial interest in the Regulation S Global Note, and to debit, or cause to be debited to, the account of the Agent Member
Transferor a beneficial interest in the Restricted Global Note, in each case having a principal amount equal to the Restricted Global Transferred Amount. 
  
 (ii) Restricted Global Note to Unrestricted Global Note. If an Owner Transferor wishes at any time to transfer a beneficial
interest in a Restricted Global Note to an Owner Transferee who wishes to take delivery thereof in the form of a beneficial interest in an Unrestricted Global Note, such transfer may be effected, subject to the Applicable Procedures, only in
accordance with this Section 303(b)(ii). Upon receipt by the Trustee, as Security Registrar, at the Corporate Trust Office of (l) written instructions given in accordance with the Applicable Procedures from the Agent Member Transferor directing the
Trustee, as Security Registrar, to credit or cause to be credited to a specified account of an Agent Member Transferee (which may but need not be an account with Euroclear or Clearstream) a beneficial interest in the Unrestricted Global Note in a
principal amount equal to the Restricted Global Transferred Amount, (2) a written order given in accordance with the Applicable Procedures containing information regarding the account of the Agent Member Transferee to be credited with, and the
account of the Agent Member Transferor to be debited for, the Restricted Global Transferred Amount, and (3) a certificate in substantially the form set forth in Annex B given by the Owner Transferor, the Trustee, as Security Registrar, shall
instruct the Depositary to reduce the principal amount of the Restricted Global Note, and to increase the principal amount of the Unrestricted Global Note, by the Restricted Global Transferred Amount, and to credit, or cause to be credited to, the
account of the Agent Member Transferee a beneficial interest in the Unrestricted Global Note, and to debit, or cause to be debited to, the account of the Agent Member Transferor a beneficial interest in the Restricted Global Note, in each case
having a principal amount equal to the Restricted Global Transferred Amount. 
  
 (iii) Regulation S Global Note or Unrestricted Global Note to Restricted Global Note. If an Owner Transferor wishes at any time to transfer a beneficial interest in a Regulation S Global Note or an Unrestricted
Global Note to an Owner Transferee who wishes to take delivery thereof in the form of a beneficial interest in a Restricted Global Note, such transfer may be effected, subject to the Applicable Procedures, only in accordance with this Section
303(b)(iii). Upon receipt by the Trustee, as Security Registrar, at the Corporate Trust Office of (1) written instructions given in accordance with the Applicable Procedures from the Agent Member Transferor, directing the Trustee, as Security
Registrar, to credit, or cause to be credited to, a specified account of 

  

 -20- 

 
an Agent Member Transferee a beneficial interest in the Restricted Global Note in a principal amount equal to that of the beneficial interest in the
Regulation S Global Note or Unrestricted Global Note to be so transferred, (2) a written order given in accordance with the Applicable Procedures containing information regarding the account of the Agent Member Transferee to be credited with, and
the account of the Agent Member Transferor (which, in the case of beneficial interest in the Regulation S Global Note, must be an account with Euroclear or Clearstream or both) to be debited for, such beneficial interest, and (3) with respect to a
transfer of a beneficial interest in the Regulation S Global Note (but not the Unrestricted Global Note), a certificate in substantially the form set forth in Annex C given by the Owner Transferor, the Trustee, as Security Registrar, shall instruct
the Depositary to reduce the principal amount of the Regulation S Global Note or Unrestricted Global Note, as the case may be, and increase the principal amount of the Restricted Global Note, by the principal amount of the beneficial interest in the
Regulation S Global Note or Unrestricted Global Note to be so transferred, and to credit, or cause to be credited to, the account of the Agent Member Transferee such beneficial interest in the Restricted Global Note, and to debit, or cause to be
debited to, the account of the Agent Member Transferor such beneficial interest in the Regulation S Global Note or Unrestricted Global Note, as the case may be. 
  

(c) In case of any transfer or exchange the procedures and requirements for which are not addressed in detail in this Section 303, such transfer or
exchange will be subject to such procedures and requirements as may be reasonably prescribed by the Company and the Trustee from time to time and, in the case of a transfer or exchange invoking a Global Note, the Applicable Procedures. 

 
 (d) Notwithstanding the foregoing, during the period of two years after
the Closing Date (as defined in the Purchase Agreement), the Company shall not, and shall not permit any of its Affiliates that are Subsidiaries to, purchase or agree to purchase or otherwise acquire any Restricted Notes, whether as beneficial owner
or otherwise (except as agent on behalf of and for the account of customers in the ordinary course of business as a securities broker in unsolicited broker’s transactions) unless, immediately upon any such purchase, the Company or any such
Affiliate shall submit such Restricted Notes to the Trustee for cancellation. The Company further agrees to ask its Affiliates that are not Subsidiaries to agree not to purchase or otherwise acquire any Restricted Notes, whether as beneficial owner
or otherwise, except as permitted in the preceding sentence.
