and the Exchange Offer shall be deemed to have been consummated notwithstanding any such extension of the tender period. 
  

 6 

 The Company and the Guarantor shall commence the Exchange Offer by mailing the related
Prospectus, appropriate letters of transmittal and other accompanying documents to each Holder stating, in addition to such other disclosures as are required by applicable law: 

(i) that the Exchange Offer is being made pursuant to this Agreement and that all Registrable Notes validly tendered and
not properly withdrawn will be accepted for exchange; 
 (ii) the dates of acceptance for exchange (which shall
be a period of at least 20 Business Days from the date such notice is mailed) (the “Exchange Dates”); 

(iii) that any Registrable Note not tendered will remain outstanding and continue to accrue interest but will not retain
any rights under this Agreement; 
 (iv) that any Holder electing to have a Registrable Note exchanged pursuant
to the Exchange Offer will be required to surrender such Registrable Note, together with the appropriate letters of transmittal, to the institution and at the address (located in New York City) and in the manner specified in the notice, prior to the
close of business on the last Exchange Date; and 
 (v) that any Holder will be entitled to withdraw its
election, not later than the close of business on the last Exchange Date, in the manner specified in such notice. 
 As a
condition to participating in the Exchange Offer, a Holder will be required to represent to the Company and the Guarantor that (i) any Exchange Notes to be received by it will be acquired in the ordinary course of its business, (ii) at the
time of the commencement of the Exchange Offer it has no arrangement or understanding with any Person to participate in the distribution (within the meaning of the Securities Act) of the Exchange Notes in violation of the provisions of the
Securities Act, (iii) it is not an “affiliate” (within the meaning of Rule 405 under Securities Act) of the Company or the Guarantor and (iv) if such Holder is a broker-dealer, that it will receive Exchange Notes for its own
account in exchange for Registrable Notes that were acquired as a result of market-making or other trading activities, and that it will deliver, to the extent required by applicable law or regulation or SEC pronouncement, a Prospectus in connection
with any resale of such Exchange Notes. 
 As soon as practicable after the last Exchange Date, the Company and the Guarantor
shall: 
 (i) accept for exchange Registrable Notes or portions thereof validly tendered and not properly
withdrawn pursuant to the Exchange Offer; and 
  

 7 

 (ii) deliver, or cause to be delivered, to the Trustee for cancellation all
Registrable Notes or portions thereof so accepted for exchange by the Company and issue, and cause the Trustee to promptly authenticate and deliver to each Holder, Exchange Notes equal in principal amount to the principal amount of the Registrable
Notes surrendered by such Holder. 
 The Company and the Guarantor shall use their reasonable best efforts to complete the
Exchange Offer as provided above and shall comply with the applicable requirements of the Securities Act, the Exchange Act and other applicable laws and regulations in connection with the Exchange Offer. 

(b) In the event that (i) the Company and the Guarantor determine that the Exchange Offer Registration provided for in
Section 2(a) hereof is not permitted or may not be completed as soon as practicable after the last Exchange Date because it would violate any applicable law or applicable interpretations of the Staff of the SEC, or because the Exchange Notes
received by Holders are not or would not be, upon receipt, transferable by each such holder without need for further compliance with Section 5 of the Securities Act (except for the requirement to deliver a Prospectus in connection with any
resale by a Participating Broker-Dealer), (ii) the Exchange Offer is not for any other reason completed by August 31, 2010 or (iii) upon completion of the Exchange Offer any of the Initial Purchasers shall so request in connection
with any offering or sale of Registrable Notes initially purchased by it pursuant to the Purchase Agreement, the Company and the Guarantor shall use their reasonable best efforts to cause to be filed as soon as practicable after such determination,
date or request, as the case may be, a Shelf Registration Statement providing for the sale of all the Registrable Notes by the Holders thereof and to have such Shelf Registration Statement become effective under the Securities Act. 

If the Company and the Guarantor receive reasonable advance notice that they will be required to file a Shelf Registration Statement
pursuant to clause (iii) of the preceding paragraph, the Company and the Guarantor shall use their reasonable best efforts to file and have become effective under the Securities Act both an Exchange Offer Registration Statement pursuant to
Section 2(a) hereof with respect to all Registrable Notes and a Shelf Registration Statement (which may be a combined Registration Statement with the Exchange Offer Registration Statement) with respect to offers and sales of Registrable Notes
held by the Initial Purchasers after completion of the Exchange Offer. 
 The Company and the Guarantor agree to use their
reasonable best efforts to keep the Shelf Registration Statement continuously effective for a period of not less than 90 days with respect to the Registrable Notes or such shorter period that will terminate when all the Registrable Notes covered by
the Shelf Registration Statement have been sold pursuant to the Shelf Registration Statement (the “Shelf Effectiveness Period”). The Company and the Guarantor further agree to supplement or amend the Shelf Registration Statement,
the related Prospectus and any Free Writing Prospectus if 
  

 8 

 
required by the rules, regulations or instructions applicable to the registration form used by the Company and the Guarantor for such Shelf Registration Statement or by the Securities Act or by
any other rules and regulations thereunder for shelf registration or if reasonably requested by a Holder of Registrable Notes with respect to information relating to such Holder, and to use their reasonable best efforts to cause any such amendment
to become effective and such Shelf Registration Statement, Prospectus or Free Writing Prospectus, as the case may be, to become usable as soon as thereafter practicable. The Company and the Guarantor agree to furnish to the Holders of Registrable
Notes copies of any such supplement or amendment promptly after its being used or filed with the SEC. 
 (c) The Company and the
Guarantor shall pay all Registration Expenses in connection with the registration provided in Sections 2(a) and 2(b). Each Holder shall pay all underwriting discounts and commissions and transfer taxes, if any, relating to the sale or disposition of
such Holder’s Registrable Notes pursuant to the Shelf Registration Statement. 
 (d) An Exchange Offer Registration
Statement pursuant to Section 2(a) hereof will not be deemed to have become effective unless it has been declared effective by the SEC. A Shelf Registration Statement pursuant to Section 2(b) hereof will not be deemed to have become
effective unless it has been declared effective by the SEC or becomes automatically effective upon filing with the SEC as provided by Rule 462 under the Securities Act. Any obligation to file with the SEC a Shelf Registration Statement pursuant to
Section 2(b) hereof will be deemed to be satisfied if the Company has previously filed a registration statement with the SEC that may be used without limitation or restriction for the purposes contemplated by Section 2(b) hereof.

 (e) In the event that either the Exchange Offer is not completed or the Shelf Registration Statement, if required hereby, has
not become effective under the Securities Act on or prior to August 31, 2010 (September 30, 2010 solely in the case of a Shelf Registration Statement required pursuant to Section 2(b)(iii) hereof), the interest rate on the Registrable
Notes will be increased by 0.50% per annum until the Exchange Offer is completed or the Shelf Registration Statement, if required hereby, become effective under the Securities Act or the Notes become freely tradable under the Securities Act, at
which time the increased interest shall cease to accrue. 
 If the Shelf Registration Statement has become
effective under the Securities Act and thereafter either ceases to be effective or the Prospectus contained therein ceases to be usable at any time during the Shelf Effectiveness Period, and such failure to remain effective or usable exists for more
than 30 days (whether or not consecutive) in any 12-month period (two suspensions not to exceed 30 days each in any 365-day period in the case of a suspension described in Section 3), then the interest rate on the Registrable Notes will be
increased by 0.50% per annum commencing on the 31st
day in such 12-month period and ending on such date that the 
  

 9 

 
Shelf Registration Statement has again become effective under the Securities Act or the Prospectus again becomes usable, at which time the increased interest shall cease to accrue;
provided, however, that if the Prospectus ceases to be usable because audited financial statements are required to be filed with the SEC and incorporated by reference in the Shelf Registration Statement to comply with the undertaking of the
Company and the Guarantor pursuant to Item 512(a)(4) of Regulation S-K (or any successor provision), such a suspension shall not be a suspension for purposes of the foregoing provision unless and to the extent its duration exceeds 60 days.

 3. Registration Procedures. In connection with their obligations pursuant to Sections 2(a) and 2(b) hereof, the
Company and the Guarantor shall as expeditiously as possible: 
 (a) prepare and file with the SEC a Registration Statement on
the appropriate form under the Securities Act, which form (i) shall be selected by the Company, (ii) shall, in the case of a Shelf Registration, be available for the sale of the Registrable Notes by selling Holders thereof and
(iii) shall comply as to form in all material respects with the requirements of the applicable form and include all financial statements and other information required by the SEC to be filed therewith; and use their reasonable best efforts to
cause such Registration Statement to become effective and remain effective for the applicable period in accordance with Section 2 hereof; 

(b) prepare and file with the SEC such amendments and post-effective amendments to each Registration Statement as may be necessary to

or Exchange Notes;

(d) in the case of a Shelf Registration, furnish to each Holder of Registrable Notes, to U.S. counsel for the Initial Purchasers, to
counsel for such Holders and to each Underwriter of an Underwritten Offering of Registrable Notes, if any, without charge, as many copies of each Prospectus, including each preliminary Prospectus or Free Writing Prospectus, and any amendment or
supplement thereto as they may reasonably request, in order to facilitate the sale or other disposition of the Registrable Notes thereunder; and the Company and the Guarantor consent to the use of such Prospectus, preliminary Prospectus or Free
Writing Prospectus and any amendment or supplement thereto in accordance with applicable law by each of the 
  

 10

preliminary Prospectus or Free Writing Prospectus or any amendment or supplement thereto in accordance with applicable law; 

(e) use their reasonable best efforts to register or qualify the Registrable Notes under all applicable state securities or blue sky laws
of such jurisdictions as a majority of the Holders of Registrable Notes covered by a Registration Statement shall reasonably request in writing by the time the applicable Registration Statement has become effective under the Securities Act;
cooperate with the Holders in connection with any filings required to be made with the Financial Industry Regulatory Authority; and do any and all other acts and things that may be reasonably necessary or advisable to enable each Holder to complete
the disposition in each such jurisdiction of the Registrable Notes owned by such Holder; provided that neither the Company nor the Guarantor shall be required to (i) qualify as a foreign corporation or other entity or as a dealer in
securities in any such jurisdiction where it would not otherwise be required to so qualify, (ii) file any general consent to service of process in any such jurisdiction or (iii) subject itself to taxation in any such jurisdiction if it is
not otherwise so subject; 
 (f) in the case of a Shelf Registration, notify each Holder of Registrable Notes, counsel for such
Holders and counsel for the Initial Purchasers promptly and, if requested by any such Holder or counsel, confirm such advice in writing (i) when a Registration Statement has become effective and when any post-effective amendment thereto has
been filed and becomes effective, when any Free Writing Prospectus has been filed or any amendment or supplement to the Prospectus or any Free Writing Prospectus has been filed, (ii) of any request by the SEC or any state securities authority
for amendments and supplements to a Registration Statement, Prospectus or any Free Writing Prospectus or for additional information after the Registration Statement has become effective, (iii) of the issuance by the SEC or any state securities
authority of any stop order suspending the effectiveness of a Registration Statement or the initiation of any proceedings for that purpose, including the receipt by the Company of any notice of objection of the SEC to the use of a Shelf Registration
Statement or any post-effective amendment thereto pursuant to Rule 401(g)(2) under the Securities Act, (iv) if, between the effective date of a Registration Statement and the closing of any sale of Registrable Notes covered thereby, the
representations and warranties of the Company and the Guarantor contained in any underwriting agreement, securities sales agreement or other similar agreement, if any, relating to an offering of such Registrable Notes cease to be true and correct in
all material respects or if the Company receives any notification with respect to the suspension of the qualification of the Registrable Notes for sale in any jurisdiction or the initiation of any proceeding for such purpose (to the extent that such
agreement provides for such notice), (v) of the happening of any event during the period a Shelf Registration Statement is effective that makes any statement made in such Registration Statement or the related Prospectus or any Free Writing
Prospectus untrue in any material respect or that requires the making of any changes in such Registration Statement or Prospectus or any Free Writing Prospectus 

 

 11 

 
in order to make the statements therein not misleading and (vi) of any determination by the Company or the Guarantor that a post-effective amendment to a Registration Statement or any

 (g) use their reasonable best
efforts to obtain the withdrawal of any order suspending the effectiveness of a Registration Statement or, in the case of a Shelf Registration, the resolution of any objection of the SEC pursuant to Rule 401(g)(2), including by filing an amendment

(h) use all reasonable efforts to obtain the consent or approval of each Mexican or U.S. governmental agency or authority, whether
federal or state that may be required to effect the Exchange Offer and the offering and sale of Exchange Notes;

Registrable Notes to facilitate the timely preparation and delivery of certificates representing Registrable Notes to be sold and not bearing any restrictive legends and enable such Registrable Notes to be issued in such denominations and registered

(k) in the case of a Shelf Registration, upon the occurrence of any event contemplated by Section 3(f)(v) hereof, use their
reasonable best efforts to prepare and file with the SEC a supplement or post-effective amendment to a Registration Statement or the related Prospectus or any Free Writing Prospectus or any document incorporated therein by reference or file any
other required document so that, as thereafter delivered (or, to the extent permitted by law, made available) to purchasers of the Registrable Notes, such Prospectus or Free Writing Prospectus, as the case may be, will not contain any untrue
statement of a material fact or omit to state a material fact required to be stated therein or necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading; and the Company and the Guarantor
shall notify the Holders of Registrable Notes to suspend use of the Prospectus or any Free Writing Prospectus as promptly as practicable after the occurrence of such an event, and such Holders hereby agree to suspend use of the Prospectus or any
Free Writing Prospectus, as the case may be, until the Company and the Guarantor have amended or supplemented the Prospectus or the Free Writing Prospectus, as the case may be, to correct such misstatement or omission;

Offer Registration Statement), provide copies of such document to the Initial Purchasers and U.S. counsel for the Initial Purchasers (and, in the case of a Shelf Registration Statement, to the Holders of Registrable Notes and their counsel) and make
such of the representatives of the Company and the Guarantor as shall be reasonably requested by the Initial Purchasers or such counsel (and, in the case of a Shelf Registration Statement, the Holders of Registrable Notes or their counsel) available
for discussion of such document; and, in such event, the Company and the Guarantor shall not, at any time after initial filing of a Registration Statement, use or file any Prospectus, any Free Writing Prospectus, any amendment of or supplement to a
Registration Statement or a Prospectus or a Free Writing Prospectus, or any document that is to be incorporated by reference into a Registration Statement, a Prospectus or a Free Writing Prospectus, of which the Initial Purchasers and such counsel
(and, in the case of a Shelf Registration Statement, the Holders of Registrable Notes and their counsel) shall not have previously been advised and furnished a copy or to which the Initial Purchasers or such counsel (and, in the case of a Shelf
Registration Statement, the Holders or their counsel) shall reasonably and timely object;

case may be, in a form eligible for deposit with the Depositary; 
 (n) take all reasonable action necessary to ensure that the
Exchange Notes, at the time of the consummation of the Exchange Offer (or as soon as reasonably practicable thereafter), are admitted to listing on the Luxembourg Stock Exchange and trading on the Euro MTF or the New York Stock Exchange; 

(o) cause the Indenture to be qualified under the Trust Indenture Act in connection with the registration of the Exchange Notes or
Registrable Notes, as the case may be; cooperate with the Trustee and the Holders to effect such changes to the Indenture as may be required for the Indenture to be so qualified in accordance with the terms of the Trust Indenture Act; and execute,
and use their reasonable best efforts to cause the Trustee to execute, all documents as may be required to effect such changes and all other forms and documents required to be filed with the SEC to enable the Indenture to be so qualified in a timely
manner; 
  

 13 

 (p) in the case of a Shelf Registration, make available for inspection by a representative
of Holders of Registrable Notes that confirm to the Company and the Guarantor that it is their current intention to sell Registrable Notes pursuant to a Shelf Registration (an “Inspector”), any Underwriter participating in any
disposition pursuant to such Shelf Registration Statement, and counsel and accountants designated by the Holders, at reasonable times and in a reasonable manner, all pertinent financial and other records, documents and properties of the Company and
the Guarantor as may be reasonably requested by any such Inspector, Underwriter, counsel or accountant in connection with a Shelf Registration Statement, and cause the respective officers, directors and employees of the Company and the Guarantor to
supply such information; provided that if any such information is identified in writing by the Company and the Guarantor as being confidential or proprietary, each Person receiving such information shall use such Person’s reasonable best
efforts to protect the confidentiality of such information to the extent such action is otherwise not inconsistent with, an impairment of or in derogation of the substantial and necessary rights and interests of any Inspector, Holder or Underwriter;

 (q) if reasonably requested by any Holder of Registrable Notes covered by a Registration Statement, promptly incorporate in a
Prospectus supplement or post-effective amendment such information with respect to such Holder as such Holder reasonably requests to be included therein and make all required filings of such Prospectus supplement or such post-effective amendment as
soon as the Company has received notification of the matters to be incorporated in such filing; and 
 (r) in the case of a
Shelf Registration, enter into such customary agreements and take all such other actions in connection therewith (including those requested by the Holders of a majority in principal amount of the Registrable Notes being sold) in order to expedite or
facilitate the disposition of such Registrable Notes including, but not limited to, an Underwritten Offering and in such connection, (i) to the extent possible, make such representations and warranties to the Holders and any Underwriters of
such Registrable Notes with respect to the business of the Company and the Guarantor and their respective subsidiaries, the Registration Statement, Prospectus, any Free Writing Prospectus and documents incorporated by reference or deemed
incorporated by reference, if any, in each case, in form, substance and scope as are customarily made by issuers to underwriters in underwritten offerings and confirm the same if and when requested, (ii) obtain opinions of counsel to the
Company and the Guarantor (which counsel and opinions, in form, scope and substance, shall be reasonably satisfactory to the Holders and such Underwriters and their respective counsel) addressed to each selling Holder and Underwriter of Registrable
Notes, covering the matters customarily covered in opinions requested in underwritten offerings, (iii) subject to receipt of the documentation to the extent required by Statement of Auditing Standard No. 72 (or successor pronouncements),
obtain “comfort” letters from the independent certified public accountants of the Company and the Guarantor (and, if necessary, any other certified public accountant of any subsidiary of the Company and the Guarantor, or of any business
acquired by the Company and 
  

 14 

 
the Guarantor for which financial statements and financial data are or are required to be included in the Registration Statement) addressed to each selling Holder and Underwriter of Registrable
Notes, such letters to be in customary form and covering matters of the type customarily covered in “comfort” letters in connection with underwritten offerings, including but not limited to financial information contained or incorporated
by reference in any preliminary Prospectus, Prospectus or Free Writing Prospectus, (iv) deliver such documents and certificates as may be reasonably requested by the Holders of a majority in principal amount of the Registrable Notes being sold
or the Underwriters, and which are customarily delivered in underwritten offerings, to evidence the continued validity of the representations and warranties of the Company and the Guarantor made pursuant to clause (i) above and to evidence
compliance with any customary conditions contained in an underwriting agreement. 
 In the case of a Shelf Registration
Statement, the Company and the Guarantor may require each Holder of Registrable Notes to furnish to the Company or the Guarantor, as the case may be, such information regarding such Holder and the proposed disposition by such Holder of such
Registrable Notes as the Company or the Guarantor may from time to time reasonably request in writing. 
 In the case of any
Registration Statement, each Holder of Registrable Notes agrees that, upon receipt of any notice from the Company or the Guarantor to the effect of the happening of any event of the kind described in Section 3(f)(iii) or 3(f)(iv) hereof or that
the Prospectus included in any Registration Statement cannot be used for any other reason, such Holder will forthwith discontinue disposition of Registrable Notes pursuant to such Registration Statement until such Holder’s receipt of the copies
of the supplemented or amended Prospectus and any Free Writing Prospectus contemplated by Section 3(k) hereof and, if so directed by the Company and the Guarantor, such Holder will deliver to the Company and the Guarantor all copies in its
possession, other than permanent file copies then in such Holder’s possession, of the Prospectus and any Free Writing Prospectus covering such Registrable Notes that is current at the time of receipt of such notice. The Company and the
Guarantor may give any such notice only twice during any 365-day period and any such suspensions shall not exceed 30 days for each suspension and there shall not be more than two suspensions in effect during any 365-day period; provided,
however, that if the Prospectus ceases to be usable because audited financial statements are required to be filed with the SEC and incorporated by reference in the Shelf Registration Statement to comply with the undertaking of the Company and the
Guarantor pursuant to Item 512(a)(4) of Regulation S-K (or any successor provision), such a suspension shall not be a suspension for purposes of the foregoing provision unless and to the extent its duration exceeds 60 days. 

If the Company and the Guarantor shall give any such notice to suspend the disposition of Registrable Notes pursuant to any Registration
Statement, the Company and the Guarantor shall extend the period during which the Registration Statement shall be maintained effective pursuant to this Agreement by the number of days during the period from and including the date of the giving of
such notice to and 
  

 15 

 
including the date when the Holders shall have received copies of the supplemented or amended Prospectus or any Free Writing Prospectus necessary to resume such dispositions. 

The Holders of Registrable Notes covered by a Shelf Registration Statement who desire to do so may sell such Registrable Notes in an
Underwritten Offering. In any such Underwritten Offering, the investment banker or investment bankers and manager or managers (the “Underwriters”) that will administer the offering will be selected by the Majority Holders of the
Registrable Notes included in such offering. 
 4. Participation of Broker-Dealers in Exchange Offer. (a) The Staff
of the SEC has taken the position that any broker-dealer that receives Exchange Notes for its own account in the Exchange Offer in exchange for Notes that were acquired by such broker-dealer as a result of market-making or other trading activities
(a “Participating Broker-Dealer”) may be deemed to be an “underwriter” within the meaning of the Securities Act and must deliver a prospectus meeting the requirements of the Securities Act in connection with any resale of
such Exchange Notes. 
 The Company and the Guarantor understand that it is the Staff’s position that if the Prospectus
contained in the Exchange Offer Registration Statement includes a plan of distribution containing a statement to the above effect and the means by which Participating Broker-Dealers may resell the Exchange Notes, without naming the Participating
Broker-Dealers or specifying the amount of Exchange Notes owned by them, such Prospectus may be delivered by Participating Broker-Dealers to satisfy their prospectus delivery obligation under the Securities Act in connection with resales of Exchange
Notes for their own accounts, so long as the Prospectus otherwise meets the requirements of the Securities Act. 
 (b) In light
of the above, and notwithstanding the other provisions of this Agreement, the Company and the Guarantor agree to amend or supplement the Prospectus contained in the Exchange Offer Registration Statement, as would otherwise be contemplated by
Section 3(k) hereof, for a period of up to 120 days after the last Exchange Date (as such period may be extended pursuant to the penultimate paragraph of Section 3 of this Agreement), if requested by the Initial Purchasers or by one or
more Participating Broker-Dealers, in order to expedite or facilitate the disposition of any Exchange Notes by Participating Broker-Dealers consistent with the positions of the Staff recited in Section 4(a) hereof. The Company and the Guarantor
further agree that Participating Broker-Dealers shall be authorized to deliver such Prospectus during such period in connection with the resales contemplated by this Section 4. 

(c) The Initial Purchasers shall have no liability to the Company, the Guarantor or any Holder with respect to any request that they may
make pursuant to Section 4(b) hereof. 
  

 16 

 5. Indemnification and Contribution. (a) The Company and the Guarantor, jointly
and severally, agree to indemnify and hold harmless the Initial Purchasers and each Holder, their respective affiliates, directors and officers and each Person, if any, who controls the Initial Purchasers or any Holder within the meaning of
Section 15 of the Securities Act or Section 20 of the Exchange Act, from and against any and all losses, claims, damages and liabilities (including, without limitation, legal fees and other expenses incurred in connection with any suit,
action or proceeding or any claim asserted, as such fees and expenses are incurred), joint or several, that arise out of, or are based upon, (1) any untrue statement or alleged untrue statement of a material fact contained in any Registration
Statement or any omission or alleged omission to state therein a material fact required to be stated therein or necessary in order to make the statements therein not misleading, or (2) any untrue statement or alleged untrue statement of a
material fact contained in any Prospectus, any Free Writing Prospectus or any “issuer information” (“Issuer Information”) filed or required to be filed pursuant to Rule 433(d) under the Securities Act, or any omission or alleged
omission to state therein a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading, in each case except insofar as such losses, claims, damages or liabilities
arise out of, or are based upon, any untrue statement or omission or alleged untrue statement or omission made in reliance upon and in conformity with any information furnished to the Company or the Guarantor in writing or to any selling Holder by
or on behalf of such Person expressly for use therein. In connection with any Underwritten Offering permitted by Section 3, the Company and the Guarantor, jointly and severally, will also indemnify the Underwriters, their directors and officers
and each Person who controls such Underwriters (within the meaning of the Securities Act and the Exchange Act) to the same extent as provided above with respect to the indemnification of the Holders, if requested in connection with any Registration
Statement, any Prospectus, any Free Writing Prospectus or any Issuer Information. Notwithstanding the preceding sentences of this Section 5(a), with respect to any such untrue statement in or omission from a preliminary Prospectus, the
indemnity agreement contained in this Section 5(a) shall not inure to the benefit of any Holder to the extent that the sale to the Person asserting any such loss, claim, damage or liability was an initial resale by such Holder and any such
loss, claim, damage or liability of or with respect to such Holder results from the fact that both (i) a copy of the final Prospectus (excluding any documents incorporated by reference therein) was not sent or given to such Person at or prior
to the written confirmation of the sale of such Exchange Notes to such Person and (ii) the untrue statement in or omission from such preliminary Prospectus was corrected in the final Prospectus unless, in either case, such failure to deliver
the final Prospectus was a result of non-compliance by the Company with the provisions of Section 3 hereof. 
 (b) Each
Holder agrees, severally and not jointly, to indemnify and hold harmless the Company, the Guarantor, the Initial Purchasers and the other selling Holders, their respective affiliates, the directors of the Company and the Guarantor, each officer of
the Company and the Guarantor who signed the Registration Statement 
  

 17 

 
and each Person, if any, who controls the Company, the Guarantor, any Initial Purchaser and any other selling Holder within the meaning of Section 15 of the Securities Act or Section 20
of the Exchange Act to the same extent as the indemnity set forth in Section 5(a) hereof, but only with respect to any losses, claims, damages or liabilities that arise out of, or are based upon, any untrue statement or omission or alleged
untrue statement or omission made in reliance upon and in conformity with any information relating to such Holder furnished to the Company or the Guarantor in writing by such Holder expressly for use in any Registration Statement, any Prospectus and
any Free Writing Prospectus and, subject to the limitation set forth immediately preceding this clause, shall reimburse such Persons for any legal or other expenses reasonably incurred by them in connection with investigating or defending any loss,
claim, damage, liability or action in respect thereof. 
 (c) If any suit, action, proceeding (including any governmental or
regulatory investigation), claim or demand shall be brought or asserted against any Person in respect of which indemnification may be sought pursuant to either Section 5(a) or Section 5(b) hereof, such Person (the “Indemnified
Person”) shall promptly notify the Person against whom such indemnification may be sought (the “Indemnifying Person”) in writing; provided that the failure to notify the Indemnifying Person shall not relieve it from
any liability that it may have under this Section 5 except to the extent that it has been materially prejudiced (through the forfeiture of substantive rights or defenses) by such failure; and provided, further, that the failure to
notify the Indemnifying Person shall not relieve it from any liability that it may have to an Indemnified Person otherwise than under this Section 5. If any such proceeding shall be brought or asserted against an Indemnified Person and it shall
have notified the Indemnifying Person thereof, the Indemnifying Person shall retain counsel reasonably satisfactory to the Indemnified Person to represent the Indemnified Person and any others entitled to indemnification pursuant to this
Section 5 that the Indemnifying Person may designate in such proceeding and shall pay the fees and expenses of such counsel related to such proceeding, as incurred. In any such proceeding, any Indemnified Person shall have the right to retain
its own counsel, but the fees and expenses of such counsel shall be at the expense of such Indemnified Person unless (i) the Indemnifying Person and the Indemnified Person shall have mutually agreed to the contrary; (ii) the Indemnifying
Person has failed within a reasonable time to retain counsel reasonably satisfactory to the Indemnified Person; (iii) the Indemnified Person shall have reasonably concluded that there may be legal defenses available to it that are different
from or in addition to those available to the Indemnifying Person; or (iv) the named parties in any such proceeding (including any impleaded parties) include both the Indemnifying Person and the Indemnified Person and representation of both
parties by the same counsel would be inappropriate due to actual or potential differing interests between them. It is understood and agreed that the Indemnifying Person shall not, in connection with any proceeding or related proceeding in the same
jurisdiction, be liable for the fees and expenses of more than one separate firm (in addition to any local counsel) for all Indemnified Persons, and that all such fees and expenses shall be reimbursed as they

  

 18 

 
are incurred. Any such separate firm (x) for the Initial Purchasers, their respective affiliates, directors and officers and any control Persons of each of the Initial Purchasers shall be
jointly designated in writing by the Initial Purchasers, (y) for any Holder, its affiliates, directors and officers and any control Persons of such Holder shall be designated in writing by the Majority Holders and (z) in all other cases
shall be designated in writing by the Company. The Indemnifying Person shall not be liable for any settlement of any proceeding effected without its written consent, but if settled with such consent or if there be a final judgment for the plaintiff,
the Indemnifying Person agrees to indemnify each Indemnified Person from and against any loss or liability by reason of such settlement or judgment. Notwithstanding the foregoing sentence, if at any time an Indemnified Person shall have requested
that an Indemnifying Person reimburse the Indemnified Person for fees and expenses of counsel as contemplated by this Section 5(c), the Indemnifying Person shall be liable for any settlement of any proceeding effected without its written
consent if (i) such settlement is entered into more than 30 days after receipt by the Indemnifying Person of such request and (ii) the Indemnifying Person shall not have reimbursed the Indemnified Person in accordance with such request
prior to the date of such settlement. No Indemnifying Person shall, without the written consent of the Indemnified Person, effect any settlement of any pending or threatened proceeding in respect of which any Indemnified Person is or could have been
a party and indemnification could have been sought hereunder by such Indemnified Person, unless such settlement (A) includes an unconditional release of such Indemnified Person, in form and substance reasonably satisfactory to such Indemnified
Person, from all liability on claims that are the subject matter of such proceeding and (B) does not include any statement as to or any admission of fault, culpability or a failure to act by or on behalf of any Indemnified Person. 

(d) If the indemnification provided for in Section 5(a) and Section 5 (b) hereof is unavailable to an Indemnified Person
or insufficient in respect of any losses, claims, damages or liabilities referred to therein, then each Indemnifying Person under such Section, in lieu of indemnifying such Indemnified Person thereunder, shall contribute to the amount paid or
payable by such Indemnified Person as a result of such losses, claims, damages or liabilities (i) in such proportion as is appropriate to reflect the relative benefits received by the Company and the Guarantor from the offering of the Notes and
the Exchange Notes, on the one hand, and by the Holders from receiving Notes or Exchange Notes registered under the Securities Act, on the other hand, or (ii) if the allocation provided by clause (i) is not permitted by applicable law, in
such proportion as is appropriate to reflect not only the relative benefits referred to in clause (i) but also the relative fault of the Company and the Guarantor on the one hand and the Holders on the other in connection with the statements or
omissions that resulted in such losses, claims, damages or liabilities, as well as any other relevant equitable considerations. The relative fault of the Company and the Guarantor on the one hand and the Holders on the other shall be determined by
reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information supplied by the Company

  

 19 

 
and the Guarantor or by the Holders and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission. 

(e) The Company, the Guarantor and the Holders agree that it would not be just and equitable if contribution pursuant to this
Section 5 were determined by pro rata allocation (even if the Holders were treated as one entity for such purpose) or by any other method of allocation that does not take account of the equitable considerations referred to in
Section 5(d) hereof. The amount paid or payable by an Indemnified Person as a result of the losses, claims, damages and liabilities referred to in Section 5(d) hereof shall be deemed to include, subject to the limitations set forth above,
any legal or other expenses incurred by such Indemnified Person in connection with any such action or claim. Notwithstanding the provisions of this Section 5, in no event shall a Holder be required to contribute any amount in excess of the
amount by which the total price at which the Notes or Exchange Notes sold by such Holder exceeds the amount of any damages that such Holder has otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or
alleged omission. No Person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any Person who was not guilty of such fraudulent misrepresentation.

 (f) The remedies provided for in this Section 5 are not exclusive and shall not limit any rights or remedies that may
otherwise be available to any Indemnified Person at law or in equity. 
 (g) The indemnity and contribution provisions contained
in this Section 5 shall remain operative and in full force and effect regardless of (i) any termination of this Agreement, (ii) any investigation made by or on behalf of the Initial Purchasers or any Holder, their respective
affiliates or any Person controlling each of the Initial Purchasers or any Holder, or by or on behalf of the Company or the Guarantor, their respective affiliates or the officers or directors of or any Person controlling the Company or the
Guarantor, (iii) acceptance of any of the Exchange Notes and (iv) any sale of Registrable Notes pursuant to a Shelf Registration Statement. 

6. General. 

(a) Rule 144 and Rule 144A. If the Company ceases to be subject to the reporting requirements of Section 13 or 15 of the
Exchange Act, the Company covenants that it will upon the request of any Holder or beneficial owner of Registrable Notes (i) make publicly available such information (including, without limitation, the information specified in Rule 144(c)(2)
under the Securities Act) as is necessary to permit sales pursuant to Rule 144 under the Securities Act, (ii) deliver or cause to be delivered, promptly following a request by any Holder or beneficial owner of Registrable Notes or any
prospective purchaser or transferee designated by such Holder or beneficial owner, such information (including, without limitation, the information specified in Rule 144A(d)(4) under the Securities Act) as is necessary to permit sales

  

 20 

 
pursuant to Rule 144A under the Securities Act, and (iii) take such further action that is reasonable in the circumstances, in each case to the extent required from time to time to
enable such Holder to sell its Registrable Notes without registration under the Securities Act within the limitation of the exemptions provided by (A) to the extent applicable, Rule 144 under the Securities Act, as such Rule may be amended from
time to time, (B) Rule 144A under the Securities Act, as such Rule may be amended from time to time, or (C) any similar rules or regulations hereafter adopted by the SEC. 

(b) Specific Performance. The Company and the Guarantor acknowledge that there would be no adequate remedy at law if the Company
and the Guarantor failed to perform any of their obligations in this Agreement (including, without limitation, their obligations under Section 2(a) and Section 2(b) hereof) and that any such failure may result in material irreparable
injuries to the Initial Purchasers and the Holders from time to time of the Registrable Notes and that it will not be possible to measure damages for such injuries precisely, and, accordingly the Company and the Guarantor agree that the Initial
Purchasers and such Holders, in addition to any other remedy to which they may be entitled at law or in equity, shall be entitled to compel specific performance of the obligations of the Company and the Guarantor under this Agreement in accordance
with the terms and conditions of this Agreement, in any U.S. federal or New York court located in the Borough of Manhattan, The City of New York. 

(c) No Inconsistent Agreements. The Company and the Guarantor represent, warrant and agree that (i) the rights granted to the
Holders hereunder do not in any way conflict with and are not inconsistent with the rights granted to the holders of any other outstanding securities issued or guaranteed by the Company and the Guarantor under any other agreement and
(ii) neither the Company nor the Guarantor has not entered into, or on or after the date of this Agreement will enter into, any agreement that is inconsistent with the rights granted to the Holders of Registrable Notes in this Agreement or
otherwise conflicts with the provisions hereof. 
 (d) Amendments and Waivers. The provisions of this Agreement,
including the provisions of this sentence, may not be amended, modified or supplemented, and waivers or consents to departures from the provisions hereof may not be given unless the Company and the Guarantor have obtained the written consent of
Holders of at least a majority in aggregate principal amount of the outstanding Registrable Notes affected by such amendment, modification, supplement, waiver or consent; provided that no amendment, modification, supplement, waiver or consent
to any departure from the provisions of Section 5 hereof shall be effective as against any Holder of Registrable Notes unless consented to in writing by such Holder. Any amendments, modifications, supplements, waivers or consents pursuant to
this Section 6(c) shall be by a writing executed by each of the parties hereto. 
 (e) Notices. All notices and
other communications provided for or permitted hereunder shall be made in writing by hand-delivery, registered first-class mail, telex, telecopier, or any courier guaranteeing overnight delivery (i) if to a Holder, at

  

 21 

 
the most current address given by such Holder to the Company by means of a notice given in accordance with the provisions of this Section 6(d), which address initially is, with respect to
the Initial Purchasers, the address set forth in the Purchase Agreement; (ii) if to the Company and the Guarantor, initially at the Company’s address set forth in the Purchase Agreement and thereafter at such other address, notice of which
is given in accordance with the provisions of this Section 6(d); and (iii) to such other persons at their respective addresses as provided in the Purchase Agreement and thereafter at such other address, notice of which is given in
accordance with the provisions of this Section 6(d). All such notices and communications shall be deemed to have been duly given: at the time delivered by hand, if personally delivered; five Business Days after being deposited in the mail,
postage prepaid, if mailed; when answered back, if telexed; when receipt is acknowledged, if telecopied; and on the next Business Day if timely delivered to an air courier guaranteeing overnight delivery. Copies of all such notices, demands or other
communications shall be concurrently delivered by the Person giving the same to the Trustee, at the address specified in the Indenture. 

(f) Successors and Assigns. This Agreement shall inure to the benefit of and be binding upon the successors, assigns and
transferees of each of the parties, including, without limitation and without the need for an express assignment, subsequent Holders; provided that nothing herein shall be deemed to permit any assignment, transfer or other disposition of
Registrable Notes in violation of the terms of the Purchase Agreement or the Indenture. If any transferee of any Holder shall acquire Registrable Notes in any manner, whether by operation of law or otherwise, such Registrable Notes shall be held
subject to all the terms of this Agreement, and by taking and holding such Registrable Notes such Person shall be conclusively deemed to have agreed to be bound by and to perform all of the terms and provisions of this Agreement and such Person
shall be entitled to receive the benefits hereof. The Initial Purchasers (in their capacity as Initial Purchasers) shall have no liability or obligation to the Company and the Guarantor with respect to any failure by a Holder to comply with, or any
breach by any Holder of, any of the obligations of such Holder under this Agreement. 
 (g) Third-Party Beneficiaries.
Each Holder shall be a third-party beneficiary to the agreements made hereunder between the Company and the Guarantor, on the one hand, and the Initial Purchasers, on the other hand, and shall have the right to enforce such agreements directly to
the extent it deems such enforcement necessary or advisable to protect its rights or the rights of other Holders hereunder. 

(h) Purchases and Sales of Notes. The Company and the Guarantor shall not, and shall use their reasonable best efforts to cause
their affiliates (as defined in Rule 405 under the Securities Act) not to, purchase and then resell or otherwise transfer any Registrable Notes. 
  

 22 

 (i) Counterparts. This Agreement may be executed in any number of counterparts and by
the parties hereto in separate counterparts, each of which when so executed shall be deemed to be an original and all of which taken together shall constitute one and the same agreement. 

(j) Jurisdiction, Venue and Service of Process. Each of the parties hereto hereby submits to the jurisdiction
of any U.S. federal or New York state court in the Borough of Manhattan, The City of New York or to the courts of its own corporate domicile, in respect of actions brought against it as a defendant, in any legal suit, action or proceeding based on
or arising under this Agreement and agrees that all claims in respect of such suit or proceeding may be determined in any such court. Each of the Company and the Guarantor waives, to the extent permitted by law, the defense of an inconvenient forum
or objections to personal jurisdiction with respect to the maintenance of such legal suit, action or proceeding. Each of the Company and the Guarantor hereby designates and appoints CT Corporation System, 111 Eighth Avenue,
13th Floor, New York, New York 10011 (the “Process
Agent”), as its authorized agent, upon whom process may be served in any such legal suit, action or proceeding based on or arising under this Agreement, it being understood that the designation and appointment of CT Corporation System as
such authorized agent shall become effective immediately without any further action on the part of the Company or the Guarantor. Such appointment shall be irrevocable to the extent permitted by applicable law and subject to the appointment of a
successor agent in the United States on terms substantially similar to those contained in this Section 6(j). If the Process Agent shall cease to act as agent for service of process, the Company and the Guarantor shall each appoint, without
unreasonable delay, another such agent, and notify the holders of such appointment. Each of the Company and the Guarantor represents to the holders that it has notified the Process Agent of such designation and appointment and that the Process Agent
has accepted the same in writing. Each of the Company and the Guarantor hereby authorizes and directs the Process Agent to accept such service. Each of the Company and the Guarantor further agrees that service of process upon the Process Agent and
written notice of said service to such party shall be deemed in every respect effective service of process upon the Company, in any such legal suit, action or proceeding. Nothing herein shall affect the right of any holder or any person controlling
any holder to serve process in any other manner permitted by law. 
 (k) Additional Amounts. If any amounts to be
received by the Initial Purchasers or the Holders under this Agreement are subject to any present or future taxes, assessments, deductions, withholdings, governmental charges or charges of any nature imposed or levied by or on behalf of Mexico or
any political subdivision thereof or taxing authority therein (“Mexican Taxes”), then the Company and the Guarantor shall, jointly and severally, pay to the Initial Purchasers and the Holders, an additional amount so that the
Initial Purchasers and the Holders, shall retain, after taking into consideration all such Mexican Taxes, an amount equal to the amounts owed to them under this Agreement as if such amounts had not been subject to Mexican Taxes. If any Mexican Taxes
are collected by deduction or withholding, the Company and the Guarantor shall, 
  

 23 

 
upon request provide to the Initial Purchasers and the Holders, copies of documentation evidencing the transmittal to the proper authorities of the amount of Mexican Taxes deducted or withheld.
Notwithstanding the preceding sentences of this Section 6(k), any withholding or deduction of Mexican Taxes in respect of payments under the Notes (as opposed to amounts to be received by the Initial Purchasers or the Holders under this
Agreement) shall be subject to the gross-up provisions of the Notes and the Indenture. 
 (l) Judgment Currency. The
Company and the Guarantor, jointly and severally, shall indemnify the Initial Purchasers and the Holders against any loss incurred by them as a result of any judgment or order against the Company or the Guarantor being given or made and expressed
and paid in a currency (“Judgment Currency”) other than U.S. dollars and as a result of any variation as between (i) the rate of exchange at which the U.S. dollar 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, New York at which the Initial Purchasers on the date of payment of such judgment or order are able to purchase U.S. dollars with the amount of the Judgment Currency
actually received by the Initial Purchasers. The foregoing indemnity shall constitute a separate and independent obligation of the Company and the Guarantor 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, U.S. dollars. 

(m) Headings. The headings in this Agreement are for convenience of reference only, are not a part of this Agreement and shall not
limit or otherwise affect the meaning hereof. 
 (n) Severability. The remedies provided herein are cumulative and not
exclusive of any remedies provided by law. If any term, provision, covenant or restriction of this Agreement is held by a court of competent jurisdiction to be invalid, illegal, void or unenforceable, the remainder of the terms, provisions,
covenants and restrictions set forth herein shall remain in full force and effect and shall in no way be affected, impaired or invalidated, and the parties hereto shall use their reasonable best efforts to find and employ an alternative means to
achieve the same or substantially the same result as that contemplated by such term, provision, covenant or restriction. It is hereby stipulated and declared to be the intention of the parties that they would have executed the remaining terms,
provisions, covenants and restrictions without including any of such that may be hereafter declared invalid, illegal, void or unenforceable. 

(o) Governing Law. This Agreement shall be governed by, and construed in accordance with, the laws of the State of New York.

 (p) Miscellaneous. This Agreement contains the entire agreement between the parties relating to the subject matter
hereof and supersedes all oral statements and prior writings with respect thereto. If any term, provision, covenant or 

 

 24 

 
restriction contained in this Agreement is held by a court of competent jurisdiction to be invalid, void or unenforceable or against public policy, the remainder of the terms, provisions,
covenants and restrictions contained herein shall remain in full force and effect and shall in no way be affected, impaired or invalidated. The Company, the Guarantor and the Initial Purchasers shall endeavor in good faith negotiations to replace
the invalid, void or unenforceable provisions with valid provisions the economic effect of which comes as close as possible to that of the invalid, void or unenforceable provisions. 

 

 25 

 IN WITNESS WHEREOF, the parties have executed this Agreement as of the date first written

GENERAL TERMS AND CONDITIONS OF THE NOTES 

Section 201. Designation, Principal Amount and Interest Rate. 

(a) There is hereby authorized and established a series of Securities designated the “3.625% Senior Notes due 2015,” initially
in an aggregate principal amount of U.S.$750,000,000 (which amount does not include Notes authenticated and delivered upon registration of transfer of, in exchange for, or in lieu of, other Securities of such series pursuant to Sections 304, 305,
306, 906 or 1205 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. 
 (b) The Company may, from time to time and without the consent of the Holders, issue additional notes,
with Guarantees of the Guarantor duly annexed thereto or endorsed thereon, on terms and conditions identical to those of the Notes (except for issue date, issue price and the date from which interest shall accrue and, if applicable, first be paid),
which additional notes, together with Guarantees of the Guarantor duly annexed thereto or endorsed thereon, shall increase the aggregate principal amount of, and shall be consolidated and form a single series with, the Notes. 

(c) The Company may issue Exchange Notes, with Guarantees of the Guarantor duly annexed thereto or endorsed thereon, pursuant to an
Exchange Offer, in each case pursuant to a Board Resolution and subject to Section 303 of the Base Indenture, in authorized denominations in exchange for a like principal amount of the Original Notes. Upon any such exchange of Original Notes,
the Original Notes so exchanged shall be canceled in accordance with Section 308 of the Base Indenture and shall no longer be deemed Outstanding for any purpose. The Original Notes and any Exchange Notes shall vote and consent together on all
matters as one class and none of the Original Notes nor the Exchange Notes shall have the right to vote or consent as a class separate from one another on any matter. 

(d) The Stated Maturity of the Notes shall be March 30, 2015. The Notes shall bear interest at the rate of 3.625% per annum
from March 30, 2010 or from the most recent Interest Payment Date to which interest has been paid or duly provided for, as the case may be, payable semi-annually in arrears on March 30 and September 30, commencing on
September 30, 2010, until the principal thereof is paid or 
  

 4 

 
made available for payment on or prior to the Stated Maturity of the Notes; provided, however, that, with respect to any Registrable Notes, if a Registration Default occurs, such
Registrable Notes shall bear additional interest as a result thereof (at an incremental rate per annum of 0.50%), as liquidated damages and not as a penalty, from the day such Registration Default occurs to but not including the first day thereafter
that no Registration Default is continuing, all in accordance with the provisions of the Registration Rights Agreement, payable on each Interest Payment Date commencing on the first Interest Payment Date after the day on which such Registration
Default occurs; and provided, further, 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. Denominations. 

The Notes shall be issued only in denominations of U.S.$100,000 and integral multiples of U.S.$1,000 in excess thereof. 

Section 203. Payment of Additional Amounts. 

Section 1009(a) of the Base Indenture is hereby amended and restated in its entirety with respect to the Notes (but not with respect
to any other series of Securities) as follows: 
 “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 are imposed solely because of (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 with Mexico of 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, 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;

 (ii) of any such taxes, duties, assessments or other governmental charges with respect to such 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; 
  

 5 

 (iii) of estate, inheritance, gift or other similar taxes, assessments or
other governmental charge imposed with respect to such Note; 
 (iv) of any tax, duty, assessment or other
governmental charge payable otherwise than by deduction or withholding from payments on such Note; 
 (v) of any
payment on such 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; and 

(vi) of any tax, duty, assessment or governmental charge imposed on a payment to an individual and required to be made
pursuant to any law implementing or complying with, or introduced in order to conform to, any European Union Directive on the taxation of savings. 

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 (a) if 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), regulations (including proposed regulations) and administrative practice or (b) unless the provision of the information, documentation or other evidence described in such Clause (i)(B) is expressly required by the applicable
Mexican regulations 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 the applicable Mexican regulations.
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 remit the full
amount of any Mexican Taxes withheld to the applicable Mexican taxing authorities in accordance with applicable law. The Company shall also provide the Trustee with the constancia or other relevant documentation, if any (which may consist of
certified copies of such documentation), satisfactory to the Trustee evidencing the payment of Mexican Taxes in respect of which the Company has paid any Additional Amounts. Copies of such documentation shall be made available to the Holders of the
Notes or the Paying Agent, as applicable, upon request therefor. 
 In respect of the Notes issued hereunder, at least 10
days’ prior to the first date of payment of interest on the Notes 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 Notes 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 

 

 6 

 
of such Notes, 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.” 
 Section 204. Forms Generally.

 The Notes and the Guarantees annexed thereto or endorsed thereon shall be in substantially the forms set forth in this
Section 204 with such appropriate insertions, omissions, substitutions and other variations as are required or permitted by this Second 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, with Guarantees duly
annexed thereto or endorsed thereon; provided that if any Notes are issued in certificated and not global form, such Notes shall be in substantially the form set forth in this Section 204, but shall not contain the legends relating to
Global Notes or the “Schedule of Increases or Decreases in Global Note.” 
 Upon their original issuance, Notes
offered and sold to Qualified Institutional Buyers in accordance with Rule 144A shall be issued in the form of one or more Global Notes in definitive, fully registered form, with Guarantees annexed thereto or endorsed thereon, without coupons,
substantially in the form set forth in this Section 204 with such applicable legends as provided herein (each, a “Restricted Global Note”). Such Restricted 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, with Guarantees duly annexed thereto or endorsed thereon, and authenticated by the Trustee as hereinafter
provided. The aggregate amount of any Restricted 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. 

Upon their original issuance, Notes offered and sold in reliance on Regulation S shall be issued in the form of one or more Global Notes
in definitive, fully registered form, with Guarantees annexed thereto or endorsed thereon, without coupons, substantially in the form set forth in this Section 204, with such applicable legends as provided herein (each, a “Regulation S
Global Note”). Such Regulation S Global Notes shall be registered in the name of the Depositary, or its nominee, and deposited with the Trustee, at its Corporate Trustee Office, as custodian for the Depositary, duly executed by the Company,

records of the Trustee, as custodian for the Depositary, as provided in Section 206 hereof. 
 For all purposes of this
Second Supplemental Indenture, the term “Restricted Note” shall include all Notes, together with Guarantees of the Guarantor annexed thereto or endorsed thereon, issued upon registration or transfer of, in exchange for or in lieu of,
another Restricted Note except as otherwise provided in Section 206 hereof.

Note is a Registrable Note, then insert — that, upon the occurrence of a Registration Default, the per annum interest rate borne by this Note shall increase by adding 0.50% thereto, as liquidated damages and not as a penalty, for the
period from the first day on which such Registration Default occurs to but not including the first day thereafter until no Registration Default is continuing, all in accordance with the provisions of the Registration Rights Agreement, and in which
case the Company shall provide notice to the Trustee of such increase in the interest rate, and shall cause the Trustee to provide appropriate notice thereof to the Holder of this Note; and provided, further,] 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 Base Indenture. 
 Interest on the
Notes shall be computed on the basis of a 360-day year of twelve 30-day months. 
  

 9 

 The interest so payable, and punctually paid or duly provided for, on any Interest Payment
Date shall, as provided in the Indenture, be paid to the Person in whose name this Note (or one or more Predecessor Securities) is registered at the close of business on the Regular Record Date for such interest, which shall be the March 15 and
September 15 (whether or not a Business Day), as the case may be, next preceding such Interest Payment Date [if the Note is a Registrable Note, then insert —; provided that any accrued and unpaid interest (including
additional interest as a result of any Registration Default, if applicable) on this Note upon the issuance of an Exchange Note in exchange for this Note shall cease to be payable to the Holder hereof and shall be payable instead on the next Interest
Payment Date for such Exchange Note to the Holder thereof on the related Regular Record Date]. Any such interest not so punctually paid or duly provided for shall 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 Securities) 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 this Note not less than 10 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 this Note may be listed, and
upon such notice as may be required by such exchange, all as more fully provided in the Indenture. 
 Payment of the principal
of and interest on this Note shall be made at the office of the Trustee or agency of the Company in the Borough of Manhattan, The City of New York, New York and, if and for so long as the Notes are admitted to listing on the Official List of the
Luxembourg Stock Exchange and trading on the Euro MTF, at the office of the Luxembourg Paying Agent, in each case 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; 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 Security Register; and 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 in writing, the Company, or its agent at least 10 Business Days prior to the applicable payment date, shall 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 — Notwithstanding the foregoing, payment of any amount payable in respect
of a Global Note shall be made in accordance with the Applicable Procedures of the Depositary.] 
 Reference is hereby made to
the further provisions of this Note set forth on the reverse hereof, which further provisions shall for all purposes have the same effect as if set forth at this place. 

Unless the certificate of authentication hereon has been executed by the Trustee referred to on the reverse hereof by manual signature,
this Note shall not be entitled to any benefit under the Indenture or be valid or obligatory for any purpose. 
 IN WITNESS
WHEREOF, the Company has caused this instrument to be duly executed.

 (b) Form of Reverse of Note. 

This Note is one of a duly authorized issue of securities of the Company (herein collectively called the “Notes”), issued under
an Indenture, dated as of September 30, 2009 (herein called the “Base Indenture”) among the Company, Radiomóvil Dipsa, S.A. de C.V., a sociedad anónima de capital variable organized and existing under the laws of
Mexico (herein called the “Guarantor,” which term includes any successor Person under the Indenture), The Bank of New York Mellon, as Trustee (herein called the “Trustee,” which term includes any successor trustee under the
Indenture), Security Registrar, Paying Agent and Transfer Agent, as supplemented by the Second Supplemental Indenture dated as of March 30, 2010 (herein called the “Second Supplemental Indenture” and, together with the Base Indenture,
the “Indenture”), among the Company, the Guarantor, the Trustee and The Bank of New York Mellon (Luxembourg) S.A., as Luxembourg Paying Agent (herein called the “Luxembourg Paying Agent”) and Luxembourg 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 Guarantor, 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 (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
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 which case the Schedule of Increases and Decreases in Global Note attached
hereto will be correspondingly adjusted. 
 In any case where any Interest Payment Date, Redemption Date or Stated Maturity of
any Note shall not be a Business Day, then (notwithstanding any other provision of the Indenture or of the Notes) 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. 
 In the event of redemption of this Note in part only, a new Note or
Notes 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 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. 
 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 

 

 11 

 
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 are imposed solely because of (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 with Mexico of 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, 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; 

(ii) of any such taxes, duties, assessments or other governmental charges with respect to such 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 charge imposed with respect
to such Note; 
 (iv) of any tax, duty, assessment or other governmental charge payable otherwise than by
deduction or withholding from payments on such Note; 
 (v) of any payment on such 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; and 

(vi) of any tax, duty, assessment or governmental charge imposed on a payment to an individual and required to be made
pursuant to any law implementing or complying with, or introduced in order to conform to, any European Union Directive on the taxation of savings. 

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 (a) if 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

  

 12 

 
(including the United States - Mexico Income Tax Treaty), regulations (including proposed regulations) and administrative practice or (b) unless the provision of the information,
documentation or other evidence described in such Clause (i)(B) is expressly required by the applicable Mexican regulations 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 the applicable Mexican regulations. 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 Notes 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 First Supplemental
Indenture or the issuance of the Notes. 
 All references herein and in the Indenture or the Guarantees, to principal, premium,
if any, or 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, 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 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 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 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 herein and in the Indenture to principal in respect of any Note shall be deemed to mean and include any Redemption Price
payable in respect of such Note pursuant to any redemption right hereunder (and all 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 all 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 Notes upon not less than 30 nor more than 60 days’ notice, at any time: 

(i) in whole but not in part at a Redemption Price equal to the sum of (A) 100% of the outstanding principal amount of the Notes,
(B) accrued and unpaid interest on the principal amount of the Notes to but not including the Redemption Date and (C) 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 
  

 13 

 
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 of such laws, rules or regulations becomes effective on or after March 23, 2010, 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 4.9%; provided, however, that (1) no notice of redemption pursuant to this clause (i) 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 Notes 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; and 

(ii) in whole or in part, at a Redemption Price equal to the greater of (1) 100% of the outstanding principal amount of the Notes
being redeemed and (2) the sum of the present values of the remaining scheduled payments of principal and interest thereon (exclusive of interest accrued to the Redemption Date) discounted to the Redemption Date on a semi-annual basis (assuming
a 360-day year consisting of twelve 30-day months) at the Treasury Rate plus 20 basis points, plus, in the case of (1) and (2), accrued and unpaid interest on the principal amount of such Notes to but not including the Redemption Date.

 For purposes of clause (ii) above, the following terms shall have the specified meanings: 

“Treasury Rate” means, with respect to any Redemption Date, the rate per annum equal to the semi-annual 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 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 Quotations or (y) if the
Trustee obtains fewer than four such Reference Treasury Dealer Quotations, the average of all such quotations. 

“Reference Treasury Dealer” means Citigroup Global Markets Inc., Goldman, Sachs & Co. and J.P. Morgan Securities Inc.,
or their respective Affiliates which are primary United States government securities dealers and two other leading primary United States government securities dealers in New York City reasonably designated by the Company; provided, however, that if
any of the foregoing shall cease to be a primary United States government securities dealer in New York City (a “Primary Treasury Dealer”), the Company shall 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 each case as a percentage of its principal amount) quoted in writing to the Trustee by such Reference Treasury Dealer at 3:30 p.m.
(New York time) on the third Business Day preceding such Redemption Date. 
  

 14 

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

As provided in and subject to the provisions of the Indenture, the Holder of this Note 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 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 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 Note 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 Note at the times, place and rate, and in the coin
or currency, herein prescribed. 
 As provided in the Indenture and subject to certain limitations therein set forth (including,
without limitation, the restrictions on transfer under Section 202 of the Second Supplemental Indenture and Sections 202 and 304 of the Base 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, premium and interest on this Note are payable, duly endorsed by, or accompanied by a written instrument of transfer in form
satisfactory to the Company, the Guarantor 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, shall be issued to the designated transferee or transferees. 
 The Notes are
issuable only in registered form without coupons in denominations of U.S.$100,000 and integral multiples of U.S.$1,000 in excess thereof. As provided in the Indenture and subject to certain limitations therein set forth, Notes are exchangeable for a
like aggregate principal amount of Notes of like tenor of a different authorized denomination, as requested by the Holder surrendering the same. 
  

 15 

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

Prior to due presentment of this Note for registration of transfer, the Company, the Guarantor, the Trustee and any agent of the Company,
the Guarantor 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 Guarantor, the Trustee nor any such agent shall be
affected by notice to the contrary. 
 [If the Note is a Global Note, then insert — This Note is a Global
Note and is subject to the provisions of the Indenture relating to Global Securities, including the limitations in Section 202 of the Second Supplemental Indenture and Sections 202 and 304 of the Base Indenture on transfers and exchanges of
Global Notes.] 
 This Note, the Guarantees and the Indenture shall be governed by, and construed in accordance with, the laws
of the State of New York. 
 All terms used in this Note which are defined in the Indenture shall have the meanings assigned to
them in the Indenture.

GUARANTEE 
 OF

 RADIOMÓVIL DIPSA, S.A. DE C.V. 

Radiomóvil Dipsa, S.A. de C.V., a sociedad anónima de capital variable organized and existing under the laws of
Mexico (the “Guarantor”), hereby fully and unconditionally guarantees (such guarantee being referred to herein as the “Guarantee”), in accordance with the terms of the Indenture, dated as of September 30, 2009 (herein called

Indenture. 
 The obligations of the Guarantor to the Holders and to the Trustee pursuant to this Guarantee and the Indenture

 Section 206. 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 204, unless compliance with the Transfer Restrictions
shall be waived by the Company and the Guarantor in writing delivered to the Trustee. 
 Subject to the following paragraph, the
Transfer Restrictions shall cease and terminate with respect to any particular Restricted Note, and the applicable Restrictive Legend shall be removed from such Restricted Note, in the Company’s sole discretion and upon delivery of a Company
Order by the Company to the Trustee upon receipt by the Company of evidence satisfactory to it that, as of the date of determination, such Restricted Note has been transferred by the Holder (a) pursuant to an exemption from registration under
the Securities Act (if available) or (b) pursuant to an effective registration statement under the Securities Act. In the case of clause (a), the Company or the Trustee may require the delivery of any documents or other evidence (including,
without limitation, an Opinion of Counsel experienced in matters of United States federal securities laws) that the Company or the Trustee, in its sole discretion, deems necessary or appropriate to evidence compliance with any such exemption. All
references in the preceding sentence to any regulation, rule or provision thereof shall be deemed also to refer to any 

 

 18 

 
successor provisions thereof. In addition, the Company may terminate the Transfer Restrictions with respect to, and remove a Restrictive Legend from, 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 an Officer’s Certificate certifying that the Transfer Restrictions have ceased and terminated with respect to
such Note. 
 Notwithstanding the preceding paragraph, the Company may, in its sole discretion, terminate the Transfer
Restrictions with respect to, and instruct the Trustee by Company Order to remove a Restrictive Legend from, any Restricted Global Note or any Regulation S Global Note after determining that such Restricted Legend is no longer required under
applicable securities laws (which determination shall be set forth in such Company Order), in each case without delivering an Officer’s Certificate or Opinion of Counsel to the Trustee. 

At the request of the Holder and upon the surrender of such Restricted Note, together with Guarantees of the Guarantor annexed thereto or
endorsed thereon, to the Trustee or Security Registrar for exchange in accordance with the provisions of this Section 206, any Restricted Note as to which the Transfer Restrictions shall have terminated in accordance with the preceding
paragraphs 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 First Supplemental Indenture. 

The Company shall notify the Trustee in writing of the effective date of any registration statement registering any Restricted Note 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 206(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
