| | (D) | in any other circumstances falling within Article 3(2) of the Prospectus Directive;
| | --- | -----------------------------------------------------------------------------------

provided that no such offer of Securities shall result in a requirement for the publication by the Company
or any Initial Purchaser of a prospectus pursuant to Article 3 of the Prospectus Directive.

For the purposes of this provision, the expression an offer to the public in relation to any
Securities in any Relevant Member State means the communication in any form and by any means of sufficient information on the terms of the offer and the Securities to be offered so as to enable an investor to decide to purchase any Securities, as
the same may be varied in that Member State by any measure implementing the Prospectus Directive in that Member State and the expression Prospectus Directive means Directive 2003/71/EC and includes any relevant implementing measure in
each Relevant Member State.

5. Agreements. The Company agrees with each Initial Purchaser that:

(a) The Company will furnish to each Initial Purchaser and to counsel for the Initial Purchasers, without
charge, during the Distribution Period (as defined in Section 5(c) below), as many copies of the materials contained in the Disclosure Package and the Final Memorandum and any amendments and supplements thereto as they may reasonably
request.

(b) The Company will prepare a final term sheet, containing solely a description of final terms of
the Securities and the offering thereof, in the form approved by you attached as Schedule II hereto.

(c) The Company will not amend or supplement the Disclosure Package or the Final Memorandum, other than by filing
documents under the Exchange Act that are incorporated by reference therein, without the prior written consent of the Representatives, which consent, following the Closing Date, may not be unreasonably withheld; provided, however, that
prior to the earlier of (i) the completion of the distribution of the Securities by the Initial Purchasers (as determined by the Representatives and communicated to the Company) and (ii) twelve (12) months after the date of the Final
Memorandum (the Distribution Period), the Company will not file any document under the Exchange Act that is incorporated by reference in the Disclosure Package or the Final Memorandum unless, prior to such proposed filing, the Company
has furnished the Representatives with a copy of such document for their review and



12



---

the Representatives have not reasonably objected to the filing of such document. The Company will promptly advise the Representatives when any document filed under the Exchange Act that is
incorporated by reference in the Disclosure Package or the Final Memorandum shall have been filed with the Commission.

(d) If at any time prior to the completion of the Distribution Period, any event occurs as a result of which the
Disclosure Package or the Final Memorandum, as then amended or supplemented, would include any untrue statement of a material fact or omit to state any material fact necessary to make the statements therein, in the light of the circumstances under
which they were made or the circumstances then prevailing, not misleading, or if it should be necessary to amend or supplement the Disclosure Package or the Final Memorandum to comply with applicable law, the Company will promptly (i) notify
the Representatives of any such event; (ii) subject to the requirements of Section 5(c), prepare an amendment or supplement that will correct such statement or omission or effect such compliance; and (iii) supply any
supplemented or amended Disclosure Package or Final Memorandum to the several Initial Purchasers and counsel for the Initial Purchasers without charge in such quantities as they may reasonably request.

(e) Without the prior written consent of the Representatives, the Company has not given and will not give to any
prospective purchaser of the Securities any written information concerning the offering of the Securities other than materials contained in the Disclosure Package, the Final Memorandum or any other offering materials prepared by or with the prior
written consent of the Representatives. For the avoidance of doubt, the foregoing shall not apply to any written information or other materials provided to any related party in connection with the preparation, execution and delivery of the
Amendment.

(f) The Company will arrange, if necessary, for the qualification of the Securities for sale by
the Initial Purchasers under the laws of such jurisdictions as the Representatives may designate and will maintain such qualifications in effect so long as required for the sale of the Securities; provided that in no event shall the Company
be obligated to qualify to do business in any jurisdiction where it is not now so qualified or to take any action that would subject it to service of process in suits, other than those arising out of the offering or sale of the Securities, in any
jurisdiction where it is not now so subject. The Company will promptly advise the Representatives of the receipt by the Company of any notification with respect to the suspension of the qualification of the Securities for sale in any jurisdiction or
the initiation or threatening of any proceeding for such purpose.

(g) As required under Article 7 of the
Mexican Securities Market Law (Ley del Mercado de Valores), the Company will, no later than one Business Day after the Closing Date, notify the Mexican National Banking and Securities Commission (Comisión Nacional Bancaria y de
Valores) of the offering of the Securities as set forth herein, in the Disclosure Package and in the Final Memorandum.

(h) The Company shall cause to have ADSs to be delivered upon conversion of the Securities to be approved for listing on
the New York Stock Exchange.



13



---

(i) The Company will not, and will not permit any of its Affiliates to,
resell any Securities or ADSs issued upon conversion thereof that have been acquired by any of them except for, (i) in a transaction registered under the Act or (ii) in a transaction exempt from the registration requirements under the Act
if such transaction does not cause the holding periods under Rule 144 under the Act to be extended for other holders of Securities.

(j) None of the Company, its Affiliates, or any person acting on its or their behalf will, directly or indirectly, make
offers or sales of any security, or solicit offers to buy any security, under circumstances that would require the registration of the Securities or ADSs issuable upon conversion thereof under the Act.

(k) Any information provided by the Company, its Affiliates or any person acting on its or their behalf to publishers of
publicly available databases about the terms of the Securities shall include a statement that the Securities have not been registered under the Act and are subject to restrictions under Rule 144A under the Act;

(l) None of the Company, its Affiliates, or any person acting on its or their behalf will engage in any form of general
solicitation or general advertising (within the meaning of Regulation D) in connection with any offer or sale of the Securities in the United States.

(m) For so long as any of the Securities are outstanding and are restricted securities within the meaning of
Rule 144(a)(3) under the Act, the Company, during any period in which it is not subject to and in compliance with Section 13 or 15(d) of the Exchange Act or it is not exempt from such reporting requirements pursuant to and in compliance with
Rule 12g3-2(b) under the Exchange Act, will provide to each holder of such restricted securities and to each prospective purchaser (as designated by such holder) of such restricted securities, upon the request of such holder or prospective
purchaser, any information required to be provided by Rule 144A(d)(4) under the Act. This covenant is intended to be for the benefit of the holders, and the prospective purchasers designated by such holders, from time to time of such restricted
securities.

(n) The Company will cooperate with the Representatives and use its best efforts to permit the
Securities to be eligible for clearance and settlement through DTC, and any other relevant clearing system.

(o) Each of the Securities and the ADSs issuable upon conversion thereof will bear, to the extent applicable, the legend
contained in Transfer Restrictions in the Preliminary Memorandum and the Final Offering Memorandum for the time period and upon the other terms stated therein.

(p) The Company will not, for a period of 90 days following the Execution Time, without the prior written consent of
Citigroup Global Markets, Inc., directly or indirectly, (i) offer, pledge, announce the intention to sell, sell, contract to sell, sell any option or contract to purchase, purchase any option or contract to sell, grant any option, right or
warrant to purchase, or otherwise transfer or dispose of, or file with the Commission a registration under the Act or with the Comisión Nacional Bancaria y de Valores a prospectus under Mexican securities laws relating to, any of the
Companys ADSs, CPOs or ordinary shares or any securities convertible



14



---

into or exercisable or exchangeable for the Companys ADSs, CPOs or ordinary shares (other than the Securities), or publicly disclose the intention to make any of the foregoing, or
(ii) enter into any swap or other agreement that transfers, in whole or in part, any of the economic consequences of ownership of the Companys ADSs, CPOs or ordinary shares, or such other securities, whether any such transaction described
in clause (i) or (ii) above is to be settled by delivery of the Companys ADSs, CPOs or ordinary shares or such other securities, in cash or otherwise, other than (i) securities convertible into or exchangeable for the
Companys ADSs, CPOs or ordinary shares pursuant to any stock option plan, stock ownership plan or dividend reinvestment plan of the Company described in the Disclosure Package and the Final Memorandum and in effect at the Execution Time; and
(ii) any of the Companys ADSs, CPOs or ordinary shares issued upon the exercise of options outstanding as of the Execution Time, including upon conversion of mandatory convertible securities of the Company outstanding as of the Execution
Time, in both cases described in the Disclosure Package and the Final Memorandum.

(q) The Company will not
take, directly or indirectly, any action designed to or that has constituted, or that might reasonably be expected to cause or result, under the Exchange Act or otherwise, in stabilization or manipulation of the price of any security of the Company
to facilitate the sale or resale of the Securities.

(r) Between the date hereof and the Closing Date, the
Company will not do or authorize any act or thing that would result in an adjustment of the conversion price of the Securities.

(s) The Company will, for a period of twelve months following the Execution Time, furnish to the Representatives
(i) all reports or other communications (financial or other) generally made available to stockholders, and deliver such reports and communications to the Representatives as soon as they are available, unless such documents are furnished to or
filed with the Commission or any securities exchange on which any class of securities of the Company is listed and generally made available to the public and (ii) such additional information concerning the business and financial condition of
the Company as the Representatives may from time to time reasonably request (such statements to be on a consolidated basis to the extent the accounts of the Company and its subsidiaries are consolidated in reports furnished to stockholders).

(t) The Company will comply with all applicable securities and other laws, rules and regulations, including,
without limitation, the Sarbanes-Oxley Act, and use its best efforts to cause the Companys directors and officers, in their capacities as such, to comply with such laws, rules and regulations, including, without limitation, the provisions of
the Sarbanes-Oxley Act.

(u) The Company agrees to pay the costs and expenses relating to the following
matters: (i) the preparation of the Indenture, the Capped Call Transaction Documents, the issuance of the Securities, the fees of the Trustee and the issuance of the ADSs (including fees of the depositary under the ADSs Deposit Agreement for
the creation and delivery of such ADSs) upon conversion of the Securities; (ii) the preparation, printing or reproduction of the materials contained in the Disclosure Package and the Final Memorandum and each amendment or supplement to either
of them; (iii) the printing (or reproduction) and delivery (including postage,



15



---

air freight charges and charges for counting and packaging) of such copies of the materials contained in the Disclosure Package and the Final Memorandum, and all amendments or supplements to
either of them, as may, in each case, be reasonably requested for use in connection with the offering and sale of the Securities; (iv) the preparation, printing, authentication, issuance and delivery of the Securities; (v) any stamp or
transfer taxes in connection with the original issuance and sale of the Securities; (vi) the printing (or reproduction) and delivery of this Agreement, any blue sky memorandum and all other agreements or documents printed (or reproduced) and

pursuant to Section 5(f) (including filing fees and the reasonable fees and expenses of counsel for the Initial Purchasers relating to such registration and qualification); (viii) the transportation and other expenses incurred by or
on behalf of Company representatives in connection with presentations to prospective purchasers of the Securities; (ix) the fees and expenses of the Companys accountants and the fees and expenses of counsel (including local and special
counsel) for the Company; (x) fees and expenses incurred in connection with any notice to be provided to the Luxembourg regulatory authorities, including the Luxembourg Stock Exchange; and (xi) all other costs and expenses incident to the
performance by the Company of its obligations hereunder.

(v) The Company agrees to reimburse the
Representatives, on behalf of the Initial Purchasers, for all their reasonable expenses incurred in connection with the sale of the Securities provided for herein (including, without limitation, reasonable fees, disbursements and expenses of legal
advisors for the Initial Purchasers). The reimbursement obligations of the Company in respect of the legal advisors for the Initial Purchasers pursuant to this Section 5(v) and Section 7 hereof will be limited to U.S.$900,000
(excluding reimbursements in respect of disbursements and expenses of such legal advisors).

(w) The Company
will apply the aggregate net proceeds from the offering of the Securities in the manner specified in the Final Memorandum under the heading Use of Proceeds.

Section 3 hereof, to the accuracy of the statements of the Company made in any certificates pursuant to the provisions hereof, to the performance by the Company of its obligations hereunder and to the following additional conditions:

(a) The Company shall have requested and caused Skadden, Arps, Slate, Meagher & Flom LLP, special
U.S. counsel for the Company, to furnish to the Representatives its opinion, tax opinion and negative assurance letter, each dated as of the Closing Date and addressed to the Representatives, substantially in the form of Schedule III attached
hereto.



16



---

(b) The Company shall have requested and caused Mr. Ramiro G.
Villarreal, General Counsel for the Company, to furnish to the Representatives his opinion, subject to certain applicable exceptions, qualifications and conditions acceptable to the Representatives, dated as of the Closing Date and addressed to the
Representatives, substantially in the form of Schedule IV attached hereto.

(c) The Representatives
shall have received from Cleary Gottlieb Steen & Hamilton LLP and Ritch Mueller, S.C., counsel for the Initial Purchasers, such opinion or opinions, dated the Closing Date and addressed to the Representatives, with respect to the issuance
and sale of the Securities, the Indenture, the Capped Call Transaction Documents, the Disclosure Package, the Final Memorandum (as amended or supplemented at the Closing Date) and other related matters as the Representatives may reasonably require,
and the Company shall have furnished to such counsel such documents as they request for the purpose of enabling them to pass upon such matters.

(d) The Company shall have requested and caused Elvinger, Hoss & Prussen, special Luxembourg counsel for the
Company, to furnish such opinion or opinions, dated the Closing Date, providing, among other related matters as the Representatives may reasonably require, that the issuance and sale of the Securities as provided in the General Disclosure Package
and the Final Memorandum, constitutes a public offering under the laws of Luxembourg, and the Company shall have furnished to such counsel such documents as they request for the purpose of enabling them to pass upon such matters; provided,
however, that, prior to the delivery of such opinion on the Closing Date, Citigroup Global Markets, Inc. agrees to furnish a representation letter to Elvinger, Hoss & Prussen to the effect that Citigroup Global Markets, Inc. has offered
the Securities to at least five persons within the Grand Duchy of Luxembourg.

(e) The Company shall have
furnished to the Representatives a certificate of the Company, signed by an executive officer of the Company, dated as of the Closing Date, substantially in the form of Schedule V attached hereto.

(f) At the Execution Time and at the Closing Date, the Company shall have requested and caused KPMG Cárdenas
Dosal, S.C. to furnish to the Representatives, letters, dated respectively as of the Execution Time and as of the Closing Date, in form and substance satisfactory to the Representatives and confirming that they are independent auditors within the
meaning of Article 2.21 of the Mexican Institute of Public Accountants Code of Professional Conduct and within the meaning in the Act and the applicable rules and regulations thereunder adopted by the Commission and the Public Company
Accounting Oversight Board (United States), substantially in the form of Schedule VI attached hereto.

(g) Subsequent to the Execution Time or, if earlier, the dates as of which information is given in the Disclosure Package
(exclusive of any amendment or supplement thereto) and the Final Memorandum (exclusive of any amendment or supplement thereto), there shall not have been (i) any change or decrease specified in the letter or letters referred to in paragraph
(d) of this Section 6; or (ii) any change, or any development involving a prospective change, in or affecting the condition (financial or otherwise), prospects, earnings, business or properties of the Company and its
subsidiaries taken as a whole, whether or not arising from transactions in the ordinary course of business, except as set forth in or contemplated in the Disclosure Package and the Final Memorandum (exclusive of any amendment or supplement



17



---

thereto), the effect of which, in any case referred to in clause (i) or (ii) above, is, in the sole judgment of the Representatives, so material and adverse as to make it impractical or
inadvisable to proceed with the offering or delivery of the Securities as contemplated in the Disclosure Package and the Final Memorandum (exclusive of any amendment or supplement thereto).

(h) The Securities shall be eligible for clearance and settlement through DTC and any other relevant clearing system.

(i) Subsequent to the Execution Time, there shall not have been any decrease in the rating of any of the
Companys or any of its subsidiaries debt securities by Standard & Poors and Fitch Ratings or any notice given of any intended or potential decrease in any such rating. For the avoidance of doubt, any reiteration or

in this Section 6 shall not have been fulfilled when and as provided in this Agreement, or if any of the opinions and certificates mentioned above or elsewhere in this Agreement shall not be reasonably satisfactory in form and substance
to the Representatives and counsel for the Initial Purchasers, this Agreement and all obligations of the Initial Purchasers hereunder may be cancelled at, or at any time prior to, the Closing Date by the Representatives. Notice of such cancellation
shall be given to the Company in writing or by telephone or facsimile confirmed in writing.

The documents
required to be delivered under this Section 6 will be delivered at the office of counsel for the Initial Purchasers, at Cleary Gottlieb Steen & Hamilton LLP, One Liberty Plaza, New York, New York, 10006, Attention: Duane
McLaughlin, Esq., on the Closing Date.

7. Reimbursement of Expenses. If the sale of the Securities
provided for herein is not consummated because any condition to the obligations of the Initial Purchasers set forth in Section 6 hereof is not satisfied, because of any termination pursuant to Section 10 hereof or because of
any refusal, inability or failure on the part of the Company to perform any agreement herein or comply with any provision hereof other than by reason of a default by any of the Initial Purchasers, the Company will reimburse the Initial Purchasers
severally through Citigroup on demand for all expenses (including reasonable fees and disbursements of counsel subject to the limit set forth in Section 5(v) above) that shall have been incurred by them in connection with the proposed

18

8. Indemnification and Contribution. (a) The Company agrees to
indemnify and hold harmless each Initial Purchaser, the directors, officers, employees, Affiliates and agents of each Initial Purchaser and each person who controls any Initial Purchaser within the meaning of either the Act or the Exchange Act
against any and all losses, claims, damages or liabilities, joint or several, to which they or any of them may become subject under the Act, the Exchange Act or other U.S. federal or state statutory law or regulation, at common law or otherwise,
insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon any untrue statement or alleged untrue statement of a material fact contained in the Preliminary Memorandum, the Final Memorandum,
any Issuer Written Information or any other written information used by or on behalf of the Company in connection with the offer or sale of the Securities, or in any amendment or supplement thereto, or arise out of, or are based upon, the omission
or alleged omission to state therein 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 agrees to reimburse each such
indemnified party, as incurred, for any legal or other expenses reasonably incurred by it in connection with investigating or defending any such loss, claim, damage, liability or action; provided, however, that the Company will not be
liable in any such case to the extent that any such loss, claim, damage or liability arises out of or is based upon any such untrue statement or alleged untrue statement or omission or alleged omission made in the Preliminary Memorandum, the Final
Memorandum, or in any amendment thereof or supplement thereto, in reliance upon and in conformity with written information furnished to the Company by or on behalf of any Initial Purchaser through the Representatives specifically for inclusion
therein. This indemnity agreement will be in addition to any liability that the Company may otherwise have.

(b) Each Initial Purchaser severally, and not jointly, agrees to indemnify and hold harmless the Company, each of its
directors, each of its officers, and each person who controls the Company within the meaning of either the Act or the Exchange Act, to the same extent as the foregoing indemnity to each Initial Purchaser, but only with reference to written
information relating to such Initial Purchaser furnished to the Company by or on behalf of such Initial Purchaser through the Representatives specifically for inclusion in the Preliminary Memorandum, the Final Memorandum or in any amendment or
supplement thereto. This indemnity agreement will be in addition to any liability that any Initial Purchaser may otherwise have. The Company acknowledges that (i) the statements set forth in the last paragraph of the cover page regarding
delivery of the Securities, and (ii), under the heading Plan of Distribution, (A) the table of Initial Purchasers, and (B) the eighth and ninth paragraphs, in the Preliminary Memorandum and the Final Memorandum constitute the
only information furnished in writing by or on behalf of the Initial Purchasers for inclusion in the Preliminary Memorandum or the Final Memorandum or in any amendment or supplement thereto.

(c) Promptly after receipt by an indemnified party under this Section 8 of notice of the commencement of any
action, such indemnified party will, if a claim in respect thereof is to be made against the indemnifying party under this Section 8, notify the indemnifying party in writing of the commencement thereof; but the failure so to notify the
indemnifying party (i) will not relieve it from liability under paragraph (a) or (b) above unless and to the extent it did not



19



---

otherwise learn of such action and such failure results in the forfeiture by the indemnifying party of substantial rights and defenses and (ii) will not, in any event, relieve the
indemnifying party from any obligations to any indemnified party other than the indemnification obligation provided in paragraph (a) or (b) above. The indemnifying party shall be entitled to appoint counsel (including local counsel) of the
indemnifying partys choice at the indemnifying partys expense to represent the indemnified party in any action for which indemnification is sought (in which case the indemnifying party shall not thereafter be responsible for the fees and
expenses of any separate counsel, other than local counsel if not appointed by the indemnifying party, retained by the indemnified party or parties except as set forth below); provided, however, that such counsel shall be satisfactory
to the indemnified party. Notwithstanding the indemnifying partys election to appoint counsel (including local counsel) to represent the indemnified party in an action, the indemnified party shall have the right to employ separate counsel
(including local counsel), and the indemnifying party shall bear the reasonable fees, costs and expenses of such separate counsel if (i) the use of counsel chosen by the indemnifying party to represent the indemnified party would present such
counsel with a conflict of interest; (ii) the actual or potential defendants in, or targets of, any such action include both the indemnified party and the indemnifying party and the indemnified party shall have reasonably concluded that there
may be legal defenses available to it and/or other indemnified parties that are different from or additional to those available to the indemnifying party; (iii) the indemnifying party shall not have employed counsel satisfactory to the
indemnified party to represent the indemnified party within a reasonable time after notice of the institution of such action; or (iv) the indemnifying party shall authorize the indemnified party to employ separate counsel at the expense of the
indemnifying party. If none of the conditions in clauses (i) through (iv) in the preceding sentence are satisfied as to any indemnified party, it is understood that the Company shall, in connection with any one such action be liable for
the reasonable fees and expenses of only one separate firm of attorneys in each jurisdiction (and in addition to any local counsel) at any time (other than reasonable overlapping of engagements) for all such indemnified parties. An indemnifying
party will not, without the prior written consent of the indemnified parties, settle or compromise or consent to the entry of any judgment with respect to any pending or threatened claim, action, suit or proceeding in respect of which
indemnification or contribution may be sought hereunder (whether or not the indemnified parties are actual or potential parties to such claim or action) unless such settlement, compromise or consent includes an unconditional release of each
indemnified party from all liability arising out of such claim, action, suit or proceeding.

(d) In the event
that the indemnity provided in paragraph (a) or (b) of this Section 8 is unavailable to or insufficient to hold harmless an indemnified party for any reason, the Company and the Initial Purchasers severally agree to contribute
to the aggregate losses, claims, damages and liabilities (including legal or other expenses reasonably incurred in connection with investigating or defending any loss, claim, damage, liability or action) (collectively Losses) to which
the Company and one or more of the Initial Purchasers may be subject in such proportion as is appropriate to reflect the relative benefits received by the Company on the one hand and by the Initial Purchasers on the other from the offering of the
Securities; provided, however, that in no case shall any Initial Purchaser be responsible for any amount in excess of the purchase discount or commission applicable to the Securities purchased by such Initial Purchaser hereunder. If
the allocation provided by the immediately preceding sentence is unavailable for any reason, the Company and the Initial Purchasers severally shall contribute in such proportion as is appropriate to reflect not only such relative benefits but also
the relative fault of the



20



---

Company on the one hand and the Initial Purchasers on the other in connection with the statements or omissions that resulted in such Losses, as well as any other relevant equitable
considerations. Benefits received by the Company shall be deemed to be equal to the total net proceeds from the offering (before deducting expenses) received by it, and benefits received by the Initial Purchasers shall be deemed to be equal to the
total purchase discounts and commissions. Relative fault shall be determined by reference to, among other things, whether any untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates
to information provided by the Company on the one hand or the Initial Purchasers on the other, the intent of the parties and their relative knowledge, access to information and opportunity to correct or prevent such untrue statement or omission. The
Company and the Initial Purchasers agree that it would not be just and equitable if contribution were determined by pro rata allocation or any other method of allocation that does not take account of the equitable considerations referred to above.
Notwithstanding the provisions of this paragraph (d), no person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Act) shall be entitled to contribution from any person who was not guilty of such fraudulent
misrepresentation. For purposes of this Section 8, each person who controls an Initial Purchaser within the meaning of either the Act or the Exchange Act and each director, officer, employee, Affiliate and agent of an Initial Purchaser
shall have the same rights to contribution as such Initial Purchaser, and each person who controls the Company within the meaning of either the Act or the Exchange Act and each officer and director of the Company shall have the same rights to
contribution as the Company, subject in each case to the applicable terms and conditions of this paragraph (d).

9. Default by an Initial Purchaser. If any one or more Initial Purchasers shall fail to purchase and pay for any
of the Securities agreed to be purchased by such Initial Purchaser hereunder and such failure to purchase shall constitute a default in the performance of its or their obligations under this Agreement, the remaining Initial Purchasers shall be
obligated severally to take up and pay for (in the respective proportions which the principal amount of Securities set forth opposite their names in Schedule I hereto bears to the aggregate principal amount of Securities set forth opposite
the names of all the remaining Initial Purchasers) the Securities which the defaulting Initial Purchaser or Initial Purchasers agreed but failed to purchase; provided, however, that in the event that the aggregate principal amount of
Securities which the defaulting Initial Purchaser or Initial Purchasers agreed but failed to purchase shall exceed 10% of the aggregate principal amount of Securities set forth in Schedule I hereto, the remaining Initial Purchasers shall have
the right to purchase all, but shall not be under any obligation to purchase any, of the Securities, and if such non-defaulting Initial Purchasers do not purchase all the Securities, this Agreement will terminate without liability to any
non-defaulting Initial Purchaser or the Company. In the event of a default by any Initial Purchaser as set forth in this Section 9, the Closing Date shall be postponed for such period, not exceeding five Business Days, as the
Representatives and the Company shall determine in order that the required changes in the Final Memorandum or in any other documents or arrangements may be effected. Nothing contained in this Agreement shall relieve any defaulting Initial Purchaser
of its liability, if any, to the Company or any non-defaulting Initial Purchaser for damages occasioned by its default hereunder.



21



---

10. Termination. This Agreement shall be subject to termination in
the absolute discretion of the Representatives, by notice given to the Company prior to delivery of, and payment for, the Securities, if at any time prior to such delivery and payment (i) trading in the Companys CPOs in the Mexican Stock
Exchange (Bolsa Mexicana de Valores, S.A.B. de C.V.) shall have been suspended; (ii) trading in the Companys ADSs in the New York Stock Exchange shall have been suspended; (iii) trading in securities generally on the Mexican
Stock Exchange (Bolsa Mexicana de Valores, S.A.B. de C.V.) or the New York Stock Exchange shall have been suspended or limited or minimum prices shall have been established on either such exchanges; (iv) a banking moratorium shall have
been declared either by Mexican, U.S. federal or New York State authorities; or (iv) there shall have occurred any outbreak or escalation of hostilities, declaration by Mexico or the United States of a national emergency or war or other
calamity or crisis the effect of which on financial markets is such as to make it, in the sole judgment of the Representatives, impractical or inadvisable to proceed with the offering or delivery of the Securities as contemplated in the Disclosure
Package and the Final Memorandum (exclusive of any amendment or supplement thereto).

11. Representations
and Indemnities to Survive. The respective agreements, representations, warranties, indemnities and other statements of the Company or its officers and of the Initial Purchasers set forth in or made pursuant to this Agreement will remain in full
force and effect, regardless of any investigation made by or on behalf of the Initial Purchasers or the Company or any of the indemnified persons referred to in Section 8 hereof, and will survive delivery of and payment for the
Securities. The provisions of Sections 7 and 8 hereof shall survive the termination or cancellation of this Agreement.

12. Notices. All communications hereunder will be in writing and effective only on receipt, and, if sent to the
Representatives, will be mailed, delivered or telefaxed to the Citigroup General Counsel (fax no.: (212) 816-7912) and confirmed to Citigroup at 388 Greenwich Street, New York, New York 10013, Attention: General Counsel; or, if sent to the
Company, will be mailed, delivered or telefaxed to +5281-8888-4399 and confirmed to it at CEMEX, S.A.B. de C.V., Av. Ricardo Margáin, Zozaya #325, Colonia Valle del Campestre, Garza García, Nuevo León, México 66265.
Attention: Legal Department.

13. Successors. This Agreement will inure to the benefit of and be
binding upon the parties hereto and their respective successors and the indemnified persons referred to in Section 8 hereof and their respective successors, and, except as expressly set forth in Section 5(m) hereof, no other
person will have any right or obligation hereunder.

14. Jurisdiction. Each of the parties hereto
agrees that any suit, action or proceeding arising out of or based upon this Agreement or the transactions contemplated hereby may be instituted in any State or U.S. federal court in The City of New York and County of New York and in the courts of
its own domicile in respect of actions brought against such party as a defendant, and waives any objection which it may now or hereafter have to the laying of venue of any such proceeding, and irrevocably submits to the jurisdiction of such courts
in any suit, action or proceeding and waives the right to any other jurisdiction that it may be entitled to by reason of its present or future, domicile or any other reason. The Company hereby appoints Corporate Creations Network Inc., 1040 Avenue

agrees to take any and all action, including the execution and filing of any and all documents that may be necessary to continue such appointment in full force and effect as aforesaid. Service of process upon the Authorized Agent shall be deemed, in
every respect, effective service of process upon the Company. Notwithstanding the foregoing, any action arising out of or based upon this Agreement may be instituted by any Initial Purchaser, the directors, officers, employees, Affiliates and agents
of any Initial Purchaser, or by any person who controls any Initial Purchaser, in any court of competent jurisdiction in Mexico.

15. Internet Document Service. The Company hereby agrees that Citigroup may provide copies of the Preliminary
Memorandum and Final Memorandum and any other agreement or document relating to the offer and sale of the Securities, including, without limitation, the Indenture, to Xtract Research LLC (Xtract) following the Closing Date for inclusion
in an online research service sponsored by Xtract, access to which is restricted to qualified institutional buyers (as defined in Rule 144A under the Act); it being understood and agreed that the Company shall have no obligation to
update or supplement any such documents provided to Xtract.

16. Integration. This Agreement supersedes
all prior agreements and understandings (whether written or oral) between the Company and the Initial Purchasers, or any of them, with respect to the subject matter hereof.

17. Applicable Law. This Agreement will be governed by and construed in accordance with the laws of the State of
New York applicable to contracts made and to be performed within the State of New York.

18. Waiver of Jury
Trial. Each of the parties hereto hereby irrevocably waives, to the fullest extent permitted by applicable law, any and all right to trial by jury in any legal proceeding arising out of or relating to this Agreement or the transactions
contemplated hereby.

19. No Fiduciary Duty. The Company hereby acknowledges that (a) the purchase
and sale of the Securities pursuant to this Agreement is an arms-length commercial transaction between the Company, on the one hand, and the Initial Purchasers and any Affiliate through which it may be acting, on the other, (b) the
Initial Purchasers are acting as principal and not as an agent or fiduciary of the Company and (c) the Companys engagement of the Initial Purchasers in connection with the offering and the process leading up to the offering is as
independent contractors and not in any other capacity. Furthermore, the Company agrees that it is solely responsible for making its own judgments in connection with the offering (irrespective of whether any of the Initial Purchasers has advised or
is currently advising the Company on related or other matters). The Company agrees that it will not claim that the Initial Purchasers have rendered advisory services of any nature or respect, or owe an agency, fiduciary or similar duty to the
Company in connection with such transaction or the process leading thereto.

20. Currency. Each
reference in this Agreement to U.S. dollars (the relevant currency), including by use of the symbol US$, is of the essence. To the fullest extent permitted by law, the obligation of the Company in respect of any amount due
under this



23



---

Agreement will, notwithstanding any payment in any other currency (whether pursuant to a judgment or otherwise), be discharged only to the extent of the amount in the relevant currency that the
party entitled to receive such payment may, in accordance with its normal procedures, purchase with the sum paid in such other currency (after any premium and costs of exchange) on the Business Day immediately following the day on which such party
receives such payment. If the amount in the relevant currency that may be so purchased for any reason falls short of the amount originally due, the Company will pay such additional amounts, in the relevant currency, as may be necessary to compensate
for the shortfall. Any obligation of the Company not discharged by such payment will, to the fullest extent permitted by applicable law, be due as a separate and independent obligation and, until discharged as provided herein, will continue in full
force and effect.

21. Waiver of Immunity. To the extent that the Company has or hereafter may acquire
any immunity (sovereign or otherwise) from any legal action, suit or proceeding, from jurisdiction of any court or from set-off or any legal process (whether service or notice, attachment in aid or otherwise) with respect to itself or any of its
property, the Company hereby irrevocably waives and agrees not to plead or claim such immunity in respect of its obligations under this Agreement.

22. Waiver of Tax Confidentiality. Notwithstanding anything herein to the contrary, purchasers of the Securities
(and each employee, representative or other agent of a purchaser) may disclose to any and all persons, without limitation of any kind, the U.S. tax treatment and U.S. tax structure of any transaction contemplated herein and all materials of any kind
(including opinions or other tax analyses) that are provided to the purchasers of the Securities relating to such U.S. tax treatment and U.S tax structure, other than any information for which nondisclosure is reasonably necessary in order to comply
with applicable securities laws.

23. Taxes. Any and all payments of fees or other amounts due to the
Initial Purchasers under this Agreement shall, except as required by applicable law, be made without withholding or deduction for or on account of any taxes imposed by any jurisdiction. If any taxes are required to be withheld or deducted from any
such payment, the Company shall pay such additional amounts as may be necessary to ensure that the net amount actually received by the Initial Purchasers after such withholding or deduction is equal to the amount that the Initial Purchasers would
have received had no such withholding or deduction been required. At the reasonable request of the Initial Purchasers, the Company shall provide evidence of payment of taxes when due.

24. Counterparts. This Agreement may be signed in one or more counterparts, each of which shall constitute an
original and all of which together shall constitute one and the same agreement.

|Conversion Rights                              |  | Holders may convert their Notes into the Issuers ADSs (which represent CPOs, which in turn represent ordinary
shares) at an initial conversion rate of 73.5402 ADSs per $1,000 principal amount of Notes at any time prior to the close of business on the fourth Business Day (as defined in the Preliminary Offering Memorandum) immediately preceding the maturity
date for the Notes. The conversion rate is equivalent to an initial conversion price of approximately U.S.$13.60 per ADS. 
The indenture governing the Notes contains a covenant requiring the Issuer to issue sufficient Series A shares and Series B shares in
order to fulfill its obligations to deliver ADSs, within the time limits set forth in the indenture, following a conversion.

of the Notes in connection with a fundamental change as described in the Preliminary Offering Memorandum, based on the ADS price and effective date of the fundamental change.

holders option, to require the Issuer to purchase all or part of their Notes for cash at a repurchase price equal to 100% of their principal amount, plus accrued and unpaid interest (including additional interest, if any) and additional
amounts, if any, up to, but excluding, the repurchase date.
|                               | 
|Redemptions                    |  |       Other than in the event of a tax redemption, the Issuer may not redeem any Notes

|                                                     |  |       Upon the Issuer giving notice that it will redeem the Notes because of such a change
in the withholding tax treatment, holders will have the option to convert their notes as if a fundamental change had occurred.

|Use of Proceeds                                      |  | The estimated net proceeds from this offering, after deducting the initial purchasers discounts and commissions and estimated offering expenses, will be
approximately U.S.$635.5 million, assuming the initial purchasers do not exercise their over-allotment option, and approximately U.S.$699.3 million if they exercise their over-allotment option in full. The Issuer intends to use approximately
U.S.$95.4 million of the net proceeds from this offering to pay the cost of the capped call transaction described in the Preliminary Offering Memorandum and expect to use a portion of the net proceeds from the sale of additional Notes in the event
the initial purchasers exercise their over-allotment option to increase the number of ADSs underlying the capped call transaction on a proportionate basis, and the Issuer intends to use the remaining net proceeds for general corporate purposes and
to repay indebtedness, which may include indebtedness under the Financing Agreement.
|                                                     | 
|Capped Call Option                                   |  | In connection with this offering, the Issuer expects to enter into a capped call transaction with a counterparty, which is an affiliate of Citigroup Global
Markets Inc., covering, subject to customary anti-dilution adjustments, approximately 47,801,130 of the Issuers ADSs, assuming the initial purchasers do not exercise their over-allotment option. If the initial purchasers exercise their option
to purchase additional Notes to cover over-allotments, the Issuer expects to increase the number of ADSs underlying the capped call transaction on a proportionate basis. Because the capped call transaction is cash settled, it does not provide an
offset to any ADSs the Issuer may deliver to holders upon conversion of the Notes. The capped call transaction has a cap price 80% higher than the closing price of the Issuers ADSs on March 24, 2010.

January 2010, and U.S.$26,250,000 from premiums related to such issuance under the Financing Agreement of the Senior Secured Notes, which were issued at a price of U.S.$105.25 per U.S.$100 principal amount of interest from December 14, 2009,
yielding 8.477%. As permitted under the Financing Agreement, CEMEX retained approximately U.S.$115.5 million of such net proceeds from the issuance of Senior Secured Notes in January 2010 for general corporate purposes, including to repay financial
obligations outside the Financing Agreement. Also includes a mandatory pre-payment of U.S.$173.4 million under the Financing Agreement on January 13, 2010 in relation to the December U.S. Dollar-denominated and Euro-denominated note
issuances. See SummaryRecent DevelopmentsReopening of U.S. Dollar-denominated Senior Secured Notes in January 2010.

|(2) | Reflects additional application of the net proceeds from this offering. Assumes approximately U.S.$635.5 million of cash retained for general
corporate purposes and to repay indebtedness, which may include indebtedness under the Financing Agreement. Also assumes the initial purchasers do not exercise their over-allotment option. Amounts in Dollars have been converted from Pesos at an
exchange rate of Ps13.09 to U.S.$1.00, the CEMEX accounting rate as of December 31, 2009.

9.625% Senior Secured Notes due 2017 issued by CEMEX Finance LLC on December 14, 2009; also includes in the adjusted columns the U.S.$500,000,000 additional aggregate principal amount of 9.50% Senior Secured Notes due 2016 issued by CEMEX

CEMEX España, S.A.
|--- | -------------------------------------------------------------------------------------------------------------------------------------------------------------

|(10) | Under MFRS, the Notes offered hereby will be recorded as debt in the Issuers balance sheet; however, the Notes will not be considered as debt
for purposes of the leverage ratio calculations under the Financing Agreement.
|---- | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

|(11) | Under MFRS, the Mandatory Convertible Securities issued in Mexico on December 10, 2009 in exchange for CBs represent a combined instrument with
liability and equity components. The liability component, approximately Ps2,090 million (U.S.$160 million) as of December 31, 2009, corresponds to the net present value of interest payments due under the Mandatory Convertible Securities,
assuming no early conversion, and was recognized under Other Financial Obligations in the Issuers balance sheet. The equity component, approximately Ps1,971 million (U.S.$151 million) as of December 31, 2009, represents the
difference between principal amount and the liability component, and was recognized within Other equity reserves net of commissions in the Issuers balance sheet. See notes 13(A) and 17(B) to the Issuers consolidated financial
statements included elsewhere in this offering memorandum. Although the Issuer has not completed the Issuers U.S. GAAP reconciliation of the Issuers 2009 financial statements, the Issuer currently anticipates that there will be a new
reconciliation item in the Issuers U.S. GAAP reconciliation of the Issuers 2009 financial statements in respect of the Mandatory Convertible Securities, which the Issuer expects will be recorded as debt until conversion. The Issuer
cannot assure you that the Issuer will not identify additional reconciliation items or that this reconciliation item will be reflected therein in accordance with the Issuers current expectations.

|(12) | Issued by special purpose vehicles. In accordance with MFRS, these securities are accounted for as equity due to the fact that they do not have a
specified maturity date and the Issuers option to defer payment of interest. However, for purposes of the Issuers U.S. GAAP reconciliation, the Issuer record these debentures as debt and interest payments thereon as part of financial
expenses in the Issuers consolidated income statement.
|---- | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

|(13) | As used in this table, total capitalization equals short- and long-term debt plus the Mandatory Convertible Notes plus the Notes and plus total
stockholders equity.

each of such parties has complied and will comply with all aspects of the laws of all relevant jurisdictions (including the laws of its jurisdiction of organization) in connection with the transactions contemplated by, and the performance of its

Based upon the foregoing, and subject to the further qualifications set

1. The Company has been duly incorporated and is
validly existing as a corporation under the laws of Mexico, with full corporate power and authority to own or lease, as the case may be, and to operate their properties and conduct their businesses as described in the Disclosure Package and the

2. (i) The Companys authorized equity capitalization is as set forth, and conforms to the
description thereof contained, in the Disclosure Package and the Final Memorandum; (ii) the outstanding ordinary shares of the Company have been duly authorized and validly issued and are fully paid and nonassessable; (iii) the outstanding
CPOs of the Company have been duly authorized and validly issued in accordance with the CPO Trust and the CPO Deed; (iv) the outstanding ADSs of the Company have been, and the ADSs issuable upon conversion of the Securities will be, duly
authorized and validly issued pursuant to the ADS Deposit Agreement; (v) based on the initial conversion rate and without considering any fundamental change or antidilution adjustment that may occur subsequent to the Closing Date as provided in
the Indenture, the Company has duly and validly issued a sufficient number of ordinary shares, free of preemptive or similar rights, and has a sufficient number of CPOs available to be released and delivered by the CPO Trustee, for issuance of ADSs
upon conversion of the Securities, (vi) following the occurrence of a fundamental change or antidilution adjustment after the Closing Date as provided in the Indenture, any ordinary shares issued, and any CPOs released and delivered by the CPO
Trustee, for the issuance of ADSs upon conversion of the Securities against payment of the conversion price, will be duly and validly issued pursuant to the Companys bylaws, the CPO Trust and the CPO Deed, free of preemptive or similar rights;
(vii) except as set forth in the Disclosure Package and the Final Memorandum, no options, warrants or other rights to purchase, agreements or other obligations to issue, or rights to convert any obligations into or exchange any securities for,
ownership interests, ordinary shares, CPOs or ADSs in the Company are outstanding, and (viii) except as otherwise set forth in the Disclosure Package and the Final Memorandum, all outstanding shares of capital stock or other equity interests of
the Companys significant subsidiaries are owned by the Company either directly or through wholly owned and majority-owned subsidiaries free and clear of any security interest, claim, lien or encumbrance.

3. Each of the Transaction Documents to which the Company is a party, has been duly authorized, executed
and delivered by the Company and constitutes a legal, valid and binding agreement, enforceable against the Company in accordance with its terms; and, in the case of the notarized Spanish translation of the Indenture, it has also been duly filed for
registration with the Public Registry of Commerce of Monterrey, Nuevo León.

4. Neither
the execution and delivery of the Transaction Documents, nor the consummation of any other of the transactions therein contemplated, nor the fulfillment of the terms thereof will conflict with, result in a breach or violation of, or imposition of
any lien, charge or encumbrance (except for the security interest created pursuant to the security agreement in the Capped Call Transaction Documents) upon any property or asset of the Company pursuant to, (i) the charter or by laws
(estatutos sociales) of the Company; (ii) the

Público de la Propiedad y del Comercio) of Monterrey Nuevo León, México, which does not affect it validity or enforceability.

6. The choice of New York state law as the governing law of the Purchase Agreement, the Indenture, the
Capped Call Transaction Documents and the issuance and sale of the Securities, is legal, valid and binding to the Company under the laws of Mexico and there is no reason why the courts of Mexico would not give effect to the choice of New York law as
the proper law of the Purchase Agreement, the Indenture, the Capped Call Transaction Documents, and the Securities; the Company has the legal capacity to sue and be sued in its own name under the laws of Mexico; the Company has the power to submit,
and has irrevocably submitted, to the jurisdiction of the New York courts and the Company has validly and irrevocably appointed Corporate Creations Network Inc. as its authorized agent under the laws of Mexico for service of process under the
Purchase Agreement, the Indenture, the Capped Call Transaction Documents, and the Securities; the irrevocable submission of the Company to the jurisdiction of the New York courts and the waiver by the Company of any immunity and any objection to the
venue of the proceeding in a New York court in the Purchase Agreement, in the Indenture, the Capped Call Transaction Documents, and in the Securities, are legal, valid and binding under the laws of Mexico and there is no reason why the courts of
Mexico would not give effect to such submission and waiver; and the courts in Mexico will recognize as valid and final, and will enforce, any final and conclusive judgment against the Company obtained in a New York court arising out of or in
relation to the obligations of the Company under the Purchase Agreement, the Indenture, the Capped Call Transaction Documents, or the Securities, without re-examination of the issues pursuant to Articles 569 and 571 of the Mexican Federal Code of
Civil Procedure and Article 1347A of the Mexican Commerce Code, which provide, inter alia, that any judgment rendered outside of Mexico may be enforced by Mexican Courts, provided that:



| | (i) | such judgment is obtained in compliance with (a) all legal requirements of the jurisdiction of the court rendering such judgment, and
(b) all legal requirements of the relevant Transaction Documents;
| | --- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



IV-3



---

| | (ii) | such judgment is not rendered in a real action (acción real);
| | ---- | -------------------------------------------------------------



| | (iii) | such judgment is final, non-appealable and authenticated by the appropriate governmental authorities, and is strictly for the payment of a certain
sum of money, provided that, under Mexican Monetary Law, payments that should be made in Mexico in foreign currency, whether by agreement or upon a judgment of a Mexican Court, may be discharged in Mexican currency at a rate of exchange for
such currency prevailing at the time of payment;
| | ----- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | (iv) | the court rendering such judgment is competent to render such judgment in accordance with applicable rules under international law and such rules
are compatible with the rules adopted under the Mexican Code of Commerce;
| | ---- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | (v) | service of process was made personally on the Company or on an appropriate Process Agent of the Company;
| | --- | --------------------------------------------------------------------------------------------------------



| | (vi) | such judgment does not contravene Mexican public policy or laws (and we have no reason to believe that a judgment based upon the Transaction
Documents would contravene Mexican public policy);
| | ---- | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | (vii) | the applicable procedure under the laws of Mexico with respect to the enforcement for foreign judgments (including the issuance of a letter rogatory
by the competent authority of such jurisdiction requesting enforcement of such judgment and the certification of such judgment as authentic by the corresponding authorities of such jurisdiction in accordance with the laws thereof) is complied with;
| | ----- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | (viii) | the courts of such jurisdiction recognize the principles of reciprocity in connection with the enforcement of Mexican judgments in such
jurisdiction; and
| | ------ | ---------------------------------------------------------------------------------------------------------------------------------------------------------



| | (ix) | the cause of action in connection with which such judgment is rendered is not the same cause of action between the same parties that is pending
before a Mexican court.
| | ---- | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------

7. Except as described in the Disclosure Package and
the Final Memorandum, with respect to non-residents of Mexico, no stamp or other issuance or transfer taxes or duties and no capital gains, income, withholding or other taxes are payable by or on behalf of the Initial Purchasers to Mexico or to any
political subdivision or taxing authority thereof or therein in connection with the sale and delivery by the Company of the Securities as contemplated in the Purchase Agreement to the Initial Purchasers, the sale and delivery by the Initial
Purchasers of the Securities as contemplated in the Purchase Agreement or the entering into or performance of the terms of the Purchase Agreement.

8. Other than as described in the Disclosure Package and the Final Memorandum, under the current laws and
regulations of Mexico, all payments of principal, premium (if any) and interest on the Securities may be paid, if applicable, by the Company to the registered holder thereof in U.S. dollars (that may be obtained through conversion of Mexican



IV-4



---

Pesos) that may be freely transferred out of Mexico, and all such payments and other distributions made to holders of the Securities who are non-residents of Mexico, will not be subject to
Mexican income, withholding or other taxes under the laws and regulations of Mexico and are otherwise free and clear of any other tax, duty withholding or deduction in Mexico and without the necessity of obtaining any governmental authorization in
Mexico.

9. It is not necessary in order to enable the Initial Purchasers, the Trustee, the
counterparty to the Capped Call Transaction Documents or the holders of the Securities to exercise or enforce any of their rights under the Purchase Agreement, the Indenture, the Capped Call Transaction Documents, or the Securities in Mexico or by
reason of the entry into and/or the performance of the Purchase Agreement, the Indenture, and the Capped Call Transaction Documents, that the Initial Purchasers or the counterparty to the Capped Call Transaction Documents should be licensed or
qualified to do business in Mexico. The Initial Purchasers, the counterparty to the Capped Call Transaction Documents and the non-Mexican holders of the Securities will not be deemed resident, domiciled, carrying on business or subject to taxation
in Mexico solely by reason of the execution, delivery, performance or enforcement of the Purchase Agreement or the Capped Call Transaction Documents.

10. Except as disclosed in the Disclosure Package and the Final Memorandum, there is no pending or, to the
best of our knowledge, threatened action, suit or proceeding by or before any court or governmental agency, authority or body or any arbitrator involving the Company or any of its subsidiaries or its or their property that is not adequately
disclosed in the Disclosure Package and the Final Memorandum, except in each case (A) for such proceedings that, if the subject of an unfavorable decision, ruling or finding would not singly or in the aggregate, have a Material Adverse Effect;
and (B) (i) the statements in the Preliminary Memorandum and the Final Memorandum under the headings Recent Developments, Managements Discussion and Analysis of Financial Condition and Results of Operations 
Recent Developments, Regulatory Matters and Legal Proceedings, Important Federal Tax Considerations, Description of Common Stock, Description of CPOs and Description of ADSs, fairly
summarize the matters therein described.

11. There is no reason to believe that the Disclosure
Package, as amended or supplemented at the Execution Time, contained any untrue statement of a material fact or omitted to state any 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, other than the financial statements and other financial information contained therein, as to which such counsel need express no opinion).

12. There is no reason to believe that the Final Memorandum, as of its date or on the Closing Date,
contained or contains any untrue statement of a material fact or omitted or omits to state any material fact necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading (in each case, other
than the financial statements and other financial information contained therein, as to which such counsel need express no opinion).

I express no opinion as to any laws other than the laws of
Mexico. In rendering my opinion, I have relied, (i) as to matters governed by United States Federal and New York law, upon the opinion of Skadden, Arps, Slate, Meagher & Flom LLP delivered pursuant to the Purchase Agreement and
(ii) as to matters of fact, on certificates of responsible officers of the Company and public officials that are furnished to the Initial Purchasers.

This opinion is subject to the following qualifications:

a. Enforcement of the Transaction Documents may be limited by concurso mercantil, bankruptcy,
insolvency, liquidation, reorganization, moratorium and other similar laws or general principles of equity affecting the rights of creditors generally;

b. Labor claims, claims of tax authorities for unpaid taxes, social security quotas, workers housing
fund quotas, retirement fund quotas, as well as claims from secured or privileged creditors, will have priority over claims of the parties to, or in connection with, the Purchase Agreement, the Indenture, the Capped Call Transaction Documents, and
the Securities;

c. In the event that proceedings are brought in Mexico seeking performance of
the obligations of the Company in Mexico, pursuant to the Mexican Monetary Law, such entity may discharge its obligations by paying any sums due in a currency other than Mexican currency, in Mexican currency at the rate of exchange prevailing in
Mexico on the date when payment is made;

d. In the event that any legal proceedings are
brought in the courts of Mexico, a Spanish translation of the documents required in such proceedings prepared by a court-approved translator would have to be approved by the court after the defendant has been given an opportunity to be heard with
respect to the accuracy of the translation, and proceedings would thereafter be based upon the translated documents;

e. Claims may become barred under the statutes of limitation, which are not waivable under Mexican law, or
may become subject to defenses or set-off or counterclaim;

f. A Mexican court may stay
proceedings held in such court if concurrent proceedings are being held elsewhere;

g. With
respect to the provisions contained in each of the Transaction Documents in connection with service of process, it should be noted that service of process by mail does not constitute personal service of process under Mexican law and, since such
service is considered to be a basic procedural requirement, if for purposes of proceedings outside Mexico service of process is made by mail, a final judgment based on such process would not be enforced by the courts of Mexico; and

h. An obligation to pay interest on interest may not be enforceable in Mexico.

This opinion is furnished only to you as representative of the Initial Purchasers and is solely for the
Initial Purchasers benefit in connection with the closing occurring today and the offering of the Securities, in each case pursuant to the Purchase Agreement and for Citibank, N.A. as counterparty under the Capped Call Transaction Documents.
Without my prior written consent, this opinion may not be used, circulated, quoted or otherwise referred to for any other purpose or relied upon by, or assigned to, any other person for any purpose, including any

other person that acquires any Securities or that seeks to assert your rights in respect of this opinion (other than an Initial Purchasers successor in interest by means of merger,
consolidation, transfer of a business or other similar transaction), except that Skadden, Arps, Slate, Meagher & Flom LLP may rely upon this opinion as to matters of the laws of the Mexico in rendering their opinion pursuant to
Section 6(a) of the Purchase Agreement.
