&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;7. <u>Indemnification and Contribution</u>.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a)&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; <u>Indemnification of the Underwriters</u>. The Company agrees to indemnify and hold harmless each Underwriter and its affiliates and the directors, officers, employees and agents of each Underwriter or any such affiliates and each person, if any, who controls such Underwriter 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, reasonable and documented 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) that arise out of, or are based upon, (i) any untrue statement or alleged untrue statement of a material fact contained in the 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 (ii) any untrue statement or alleged untrue statement of a material fact contained in the Prospectus (or any amendment or supplement thereto), any Issuer Free Writing Prospectus or the Time of Sale Disclosure Package, 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, Underwriter Information.<br>

------

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b)&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; <u>Indemnification of the Company</u>. Each Underwriter agrees, severally and not jointly, to indemnify and hold harmless the Company, its directors and officers, and each person, if any, who controls the Company 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 7(a) hereof, but only with respect to any losses, claims, damages or liabilities that arise out of, or are based upon, Underwriter Information.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(c)&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; <u>Notice and Procedures</u>. If any suit, action, proceeding (including any governmental or regulatory investigation), claim or demand will be brought or asserted against any person in respect of which indemnification may be sought pursuant to either Section 7(a) hereof or Section 7(b) hereof, such person (the "<u>Indemnified Person</u>") will promptly notify the person against whom such indemnification may be sought (the "<u>Indemnifying Person</u>") in writing; <u>provided</u> that the failure to notify the Indemnifying Person will not relieve it from any liability that it may have under Sections 7(a) and 7(b) hereof, except to the extent that it has been materially prejudiced (through the forfeiture of substantive rights or defenses) by such failure; and <u>provided</u>, <u>further</u>, that the failure to notify the Indemnifying Person will not relieve it from any liability that it may have to an Indemnified Person otherwise than under Sections 7(a) and 7(b) hereof. If any such proceeding will be brought or asserted against an Indemnified Person and it will have notified the Indemnifying Person thereof, the Indemnifying Person will retain counsel reasonably satisfactory to the Indemnified Person (who shall not, without the consent of the Indemnified Person, be counsel to the Indemnifying Person) to represent the Indemnified Person and any others entitled to indemnification pursuant to this Section 7 that the Indemnifying Person may designate in such proceeding and will pay the fees and expenses of such counsel related to such proceeding, as incurred. In any such proceeding, any Indemnified Person will have the right to retain its own counsel, but the fees and expenses of such counsel will be at the expense of such Indemnified Person unless (i) the Indemnifying Person and the Indemnified Person will 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 will 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 will 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 will be reimbursed as they are incurred. Any such separate firm for the Underwriters, their affiliates, directors and officers and any control persons of the Underwriters will be designated in writing by the Representatives on the behalf of the Underwriters, and any such separate firm for the Company and any control persons of the Company will be designated in writing by the Company. The Indemnifying Person will not be liable for any settlement of any proceeding effected without its written consent (which consent will not be unreasonably withheld), but if settled with such consent or if there be a final judgment for the plaintiff, the Indemnifying Person agrees, subject to the provisions of this Section 7, 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 will have requested that an Indemnifying Person reimburse the Indemnified Person for fees and expenses of counsel as contemplated by this Section 7(c), the Indemnifying Person will 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 will not have reimbursed the Indemnified Person in accordance with such request prior to the date of such settlement. No Indemnifying Person will, 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 or contribution could have been sought hereunder by such Indemnified Person, unless such settlement (x) 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 (y) 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.

------

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(d)&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; <u>Contribution</u>. If the indemnification provided for in Sections 7(a) and 7(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 Sections, in lieu of indemnifying such Indemnified Person thereunder, will 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 on the one hand and the Underwriters on the other from the offering of the Securities 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 on the one hand and the Underwriters 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 benefits received by the Company on the one hand and the Underwriters on the other will be deemed to be in the same respective proportions as the net proceeds (before deducting expenses) received by the Company from the sale of the Securities and the total discounts and commissions received by the Underwriters in connection therewith, as provided in the Pricing Agreement, bear to the aggregate offering price of the Securities. The relative fault of the Company on the one hand and the Underwriters on the other will 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 or by the Underwriters and the parties' relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(e)&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; <u>Limitation on Liability</u>. The Company and the Underwriters agree that it would not be just and equitable if contribution pursuant to this Section 7 were determined by <u>pro rata</u> allocation or by any other method of allocation that does not take account of the equitable considerations referred to in Section 7(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 7(d) hereof will be deemed to include, subject to the limitations set forth above, any reasonable and documented legal or other expenses incurred by such Indemnified Person in connection with any such action or claim. Notwithstanding the provisions of this Section 7, in no event will any Underwriter be required to contribute any amount in excess of the amount by which the total discounts and commissions received by such Underwriter with respect to the offering of the Securities exceeds the amount of any damages that such Underwriter 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) will be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. The Underwriters' obligations to contribute pursuant to this Section 7 are several in proportion to their respective purchase obligations hereunder and not joint.

------

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(f)&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; <u>Non-Exclusive Remedies</u>. The remedies provided for in this Section 7 are not exclusive and will not limit any rights or remedies that may otherwise be available to any Indemnified Person at law or in equity.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;8.&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; <u>Termination</u>. The Pricing Agreement may be terminated in the absolute discretion of the Representatives, by notice to the Company, if after the execution and delivery of the Pricing Agreement and prior to the Closing Date (i) trading generally will have been suspended or materially limited on the New York Stock Exchange, the NASDAQ market, the Mexican Stock Exchange or the over-the-counter market in the United States or Mexico or minimum prices will have been established on any of such exchanges or such market by such exchange or by any regulatory body having jurisdiction over such exchange or market; (ii) trading of any securities issued or guaranteed by the Company will have been suspended on any exchange or the over-the-counter market in the United States or Mexico; (iii) a material disruption in securities settlement, payment or clearance services in the United States or Mexico will have occurred; (iv) a general moratorium on commercial banking activities will have been declared by U.S. federal or New York State authorities or by Mexican authorities; (v) there will have occurred any outbreak or escalation of hostilities or any change in financial markets or any calamity or crisis that in the judgment of the Representatives is material and adverse and makes it impracticable or inadvisable to proceed with the offering, sale or delivery of the Securities on the terms and in the manner contemplated by the Pricing Agreement and the Prospectus; (vi) any material adverse change or development involving a prospective material adverse change in taxation, exchange controls or other applicable law or regulation in the United States or Mexico directly affecting the Securities or the imposition of restrictions on repatriation of remittances or interest payments or dividends from Mexico, the effect of which change or development on the financial markets of the United States, Mexico or elsewhere is such as to make it inadvisable or impracticable to market the Securities; or (vii) there will have been such a material adverse change in U.S., Mexican or international monetary, general economic, political or financial conditions as to make it, in the judgment of the Representatives, inadvisable to proceed with the payment for and delivery of the Securities.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;9. <u>Payment of Expenses</u>.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a)&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; Whether or not the transactions contemplated by the Pricing Agreement are consummated or the Pricing Agreement is terminated, the Company will, subject to Section 9(b) hereof, pay or cause to be paid all fees, expenses and costs incident to the performance of its obligations hereunder, including, without limitation, (i) the costs incident to the authorization, issuance, sale, preparation and delivery of the Securities and any documentary, stamp, transfer or similar taxes payable in that connection; (ii) the costs incident to the preparation and/or printing of the Registration Statement, any Preliminary Prospectus, the Pricing Prospectus, any Issuer Free Writing Prospectus and the Prospectus (including any amendment or supplement thereto) and the distribution thereof; (iii) the costs of reproducing and distributing each of the Transaction Documents; (iv) the fees and expenses of U.S. and Mexican counsel to the Company; (v) the fees and expenses of the independent public accountants of the Company; (vi) the fees and expenses incurred in connection with the registration or qualification and determination of eligibility for investment of the Securities under the laws of such jurisdictions as the Representatives may designate; (vii) all expenses and application fees related to the admission to listing, trading and/or quotation of the Securities on any listing authority, exchange or system; (viii) any fees charged by rating agencies for rating the Securities; (ix) the fees and expenses of the Trustee and any paying agent (including related fees and expenses of any counsel to such parties); (x) any expenses and application fees incurred in connection with the approval of the Securities for book-entry transfer by DTC or other depositary; and (xi) all expenses incurred by the Company in connection with any "road show" presentation to potential investors. Notwithstanding the preceding sentence, solely if the transactions contemplated by the Pricing Agreement are consummated, the Underwriters will reimburse the Company for the fees, expenses and costs, if any, specified in the Pricing Agreement.

------

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b)&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; If (i) the Company for any reason fails to tender the Securities for delivery to the Underwriters or (ii) the Underwriters decline to purchase the Securities for any reason permitted hereunder, the Company agrees to reimburse the Underwriters for all out-of-pocket costs and expenses (including the fees and expenses of their counsel) reasonably incurred by the Underwriters in connection with the Pricing Agreement and the offering contemplated thereby.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;10. <u>Persons Entitled to Benefit of Agreement</u>. The Pricing Agreement will inure to the benefit of and be binding upon the Representatives and the Company and their respective successors and any controlling persons referred to in Section 7(b) hereof, and the affiliates, officers and directors of the Underwriters referred to in Section 7(a) hereof. Nothing in the Pricing Agreement is intended or will be construed to give any other person any legal or equitable right, remedy or claim under or in respect of the Pricing Agreement or any provision contained herein. No purchaser of Securities from the Underwriters will be deemed to be a successor merely by reason of such purchase.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;11.&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; <u>Process Agent</u>. Each of the parties hereto irrevocably agrees that any legal suit, action or proceeding arising out of or based upon the Pricing Agreement or the transactions contemplated hereby may be instituted in any U.S. federal or New York state court located in The Borough of Manhattan, The City of New York and any competent court located in the domicile of such party, with respect to actions brought against it as defendant, and irrevocably waives, to the fullest extent permitted by law, any objection which it may now or hereafter have to the laying of venue of any such proceeding and waives any right to which it may be entitled on account of place of residence or domicile and irrevocably submits to the exclusive jurisdiction of such courts in any such suit, action or proceeding. The Company has appointed CT Corporation System as its authorized agent (the "<u>Authorized Agent</u>") upon which process may be served in any such action arising out of or based on the Pricing Agreement or the transactions contemplated hereby which may be instituted in any New York court by any Underwriter or by any person who controls such Underwriter, designates CT Corporation System's address in New York City as its designated address to receive such process, expressly consents to the jurisdiction of any such court in respect of any such action, and waives any other requirements of or objections to personal jurisdiction with respect thereto.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;12.&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; <u>Survival</u>. The respective indemnities, rights of contribution, representations, warranties and agreements of the Company, on the one hand, and the Underwriters, on the other hand, contained in the Pricing Agreement or made by or on behalf of the Company or the Underwriters pursuant to the Pricing Agreement or any certificate delivered pursuant hereto will survive the delivery of and payment for the Securities and will remain in full force and effect, regardless of any termination of the Pricing Agreement or any investigation made by or on behalf of the Company or the Underwriters.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;13.&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; <u>Additional Amounts</u>. If the compensation (including the Underwriters' commissions and concessions) or any other amounts to be received by the Underwriters under the Pricing Agreement (including, without limitation, indemnification and contribution payments), as a result of entering into the Pricing Agreement, are subject to any present or future taxes, assessments, deductions, withholdings or charges of any nature imposed or levied by or on behalf of Mexico or any political subdivision thereof or taxing authority therein ("<u>Mexican Taxes</u>"), then the Company will pay to the Underwriters an additional amount so that the Underwriters will retain, after taking into consideration all such Mexican Taxes, an amount equal to the amounts owed to them as compensation or otherwise under the Pricing Agreement as if such amounts had not been subject to Mexican Taxes. If any Mexican Taxes are collected by deduction or withholding, the Company will upon request provide to the Underwriters copies of documentation evidencing the transmittal to the proper authorities of the amount of Mexican Taxes deducted or withheld.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;14.&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; <u>J</u><u>udgment Currency</u>. The Company will indemnify each Underwriter, jointly and severally, against any loss incurred by them as a result of any judgment or order against the Company, being given or made and expressed and paid in a currency ("<u>Judgment Currency</u>") 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 such Underwriter 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 such Underwriter. The foregoing indemnity will constitute a separate and independent obligation of the Company and will continue in full force and effect notwithstanding any such judgment or order as aforesaid. The term "spot rate of exchange" will include any premiums and costs of exchange payable in connection with the purchase of, or conversion into, U.S. dollars.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;15.&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; <u>Absence of Fiduciary Relationship</u>. The Company acknowledges and agrees that:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a)&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; the Underwriters have been retained solely to act as underwriters in connection with the sale of the Securities and that no fiduciary, advisory or agency relationship between the Company and the Underwriters has been created in respect of any of the transactions contemplated by the Pricing Agreement, irrespective of whether the Underwriters have advised or are advising the Company on other matters;

------

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(c)&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; any review by the Underwriters of the Company, the transactions contemplated hereby or other matters relating to such transactions will be performed solely for the benefit of the Underwriters and will not be on behalf of the Company;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(d)&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; it has been advised that the Underwriters and their affiliates are engaged in a broad range of transactions which may involve interests that differ from those of the Company and that the Underwriters have no obligation to disclose such interests and transactions to the Company by virtue of any fiduciary, advisory or agency relationship; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(e)&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; it waives, to the fullest extent permitted by law, any claims it may have against the Underwriters for breach of fiduciary duty or alleged breach of fiduciary duty and agrees that the Underwriters shall have no liability (whether direct or indirect) to the Company in respect of such a fiduciary duty claim or to any person asserting a fiduciary duty claim on behalf of or in right of the Company, including stockholders, employees or creditors of the Company.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;16.&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; <u>Miscellaneous</u>.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a)&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; <u>Notices</u>.

The headings herein are included for convenience of reference only and are not intended to be part of, or to affect the meaning or interpretation of, the Pricing Agreement.

------

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;17.&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; <u>Defaulting Underwriter</u>.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a)&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; If, on the Closing Date, any Underwriter defaults on its obligation to purchase the Securities that it has agreed to purchase hereunder, the non-defaulting Underwriters may in their discretion arrange for the purchase of such Securities by other persons satisfactory to the Company on the terms contained in this Agreement. If, within 36 hours after any such default by any Underwriter, the non-defaulting Underwriters do not arrange for the purchase of such Securities, then the Company will be entitled to a further period of 36 hours within which to procure other persons satisfactory to the non-defaulting Underwriters to purchase such Securities on such terms. If other persons become obligated or agree to purchase the Securities of a defaulting Underwriter, either the non-defaulting Underwriter or the Company may postpone the Closing Date for up to five full business days in order to effect any changes that in the opinion of counsel to the Company or counsel to the Underwriters may be necessary in the Time of Sale Disclosure Package, the Prospectus or in any other document or arrangement, and the Company agrees to promptly prepare any amendment or supplement to the Time of Sale Disclosure Package or the Prospectus that effects any such changes. As used in this Agreement, the term "Underwriter" includes, for all purposes of this Agreement unless the context otherwise requires, any person not listed in Schedule I to the Pricing Agreement that, pursuant to this Section 17, purchases Securities that a defaulting Underwriter agreed but failed to purchase.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b)&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; If, after giving effect to any arrangements for the purchase of the Securities of a defaulting Underwriter or Underwriters by the non-defaulting Underwriters and the Company as provided in Section 17(a) hereof, the aggregate principal amount of such Securities that remains unpurchased does not exceed one-eleventh of the aggregate principal amount of all the Securities, then the Company will have the right to require each non-defaulting Underwriter to purchase the principal amount of Securities that such Underwriter agreed to purchase hereunder plus such Underwriter's pro rata share (based on the principal amount of Securities that such Underwriter agreed to purchase hereunder) of the Securities of such defaulting Underwriter or Underwriters for which such arrangements have not been made.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(c)&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; If, after giving effect to any arrangements for the purchase of the Securities of a defaulting Underwriter or Underwriters by the non-defaulting Underwriters and the Company as provided in Section 17(a) hereof, the aggregate principal amount of such Securities that remains unpurchased exceeds one-eleventh of the aggregate principal amount of all the Securities, or if the Company shall not exercise the right described in Section 17(b) hereof, then this Agreement will terminate without liability on the part of the non-defaulting Underwriters. Any termination of this Agreement pursuant to this Section 17 will be without liability on the part of the Company, except that the Company will continue to be liable for the payment of expenses as set forth in Section 9(a) hereof and provided that the provisions of Section 7 hereof will not terminate and will remain in effect.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(d)&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; Nothing contained herein will relieve a defaulting Underwriter of any liability it may have to the Company or any non-defaulting Underwriter for damages caused by its default.

This Note is one of a duly authorized issue of securities of the Company (the "<u>Notes</u>"), issued under the Indenture, dated as of October 1, 2018 (the "<u>Base Indenture</u>"), among the Company, Citibank, N.A., as Trustee (the "<u>Trustee</u>," which term includes any successor trustee under the Indenture), Registrar and Transfer Agent, and Citibank, N.A., London Branch, as Paying Agent (in such capacity, the "<u>Paying Agent</u>"), as supplemented by the Seventh Supplemental Indenture, dated as of February 1, 2024, among the Company, the Trustee and Citibank, N.A., London Branch, as Paying Agent, Authenticating Agent (in such capacity, the Authenticating Agent) and London Transfer Agent (in such capacity, the "<u>London Transfer Agent</u>") (the "<u>Seventh Supplemental Indenture</u>"), as supplemented by (a) the Additional Notes Supplement to the Seventh Supplemental Indenture, dated as of July 8, 2025 (the "<u>Existing Additional Notes Supplement</u>"), and (b) the Additional Notes Supplement to the Seventh Supplemental Indenture dated as of November 25, 2025 (the "<u>Additional Notes Supplement</u>" and, together with the Base Indenture, the Seventh Supplemental Indenture and the Existing Additional Notes Supplement, the "<u>Indenture</u>"), and reference is hereby made to the Indenture for a statement of the respective rights, limitations of rights, indemnities, duties and immunities thereunder of the Company, the Trustee, the Paying Agent, each Transfer Agent, the Authenticating Agent and the Holders of the Notes and of the terms upon which the Notes are, and are to be, authenticated and delivered. The terms, conditions and provisions of this Note are those stated in the Indenture (including those made a part of the Indenture by reference to the Trust Indenture Act) and those set forth in this Note. 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, the date on which interest will 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 the 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, premium, if any, 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 ("<u>Mexican Taxes</u>"). In the event of any withholding or deduction for any Mexican Taxes, the Company shall pay such additional interest ("<u>Additional Interest</u>") 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 Interest) been required, except that no such Additional Interest 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 the Company has given the Holders at least 30 days' notice prior to the first payment date with respect to which such certification, identification or reporting requirement is required, to the effect that Holders will be required to provide such information and identification;

(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 Interest on presenting such Note for payment on any date during such 15-day period;

<br> (iii) of any estate, inheritance, gift or other similar taxes, assessments or other governmental charges imposed with respect to such Note;

<br> (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 Interest had such beneficiary, settlor, member or beneficial owner been the Holder of such Note; and

------

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

For purposes of the provisions described in Clause (i) above, the term "Holder" of any 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 Interest 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 (i) the provision of the information, documentation or other evidence described in such Clause (i)(B) is expressly required by the applicable Mexican laws and regulations (including Article 166, Section II, subsection (a) of the Mexican Income Tax Law or any substantially similar successor provision, whether included in any law or regulation), (ii) the Company cannot obtain such information, documentation or other evidence necessary to comply with the applicable Mexican laws and regulations on its own through reasonable diligence and (iii) the Company otherwise would meet the requirements for application of the applicable Mexican laws and regulations (including Article 166, Section II, subsection (a) of the Mexican Income Tax Law or any substantially similar successor provision, whether included in any law or regulation). In addition, such Clause (i)(B) shall not be construed 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.

Neither the Trustee nor the Paying Agent shall have any duty to calculate the Additional Interest nor shall they have any duty to review or verify the Company´s calculations of the Additional Interest.

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 Interest. 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 issuance of the Notes.

All references herein and in the Indenture to principal, premium, if any, interest or any other amount payable in respect of any Note shall be deemed to include all Additional Interest, 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 Interest (or Additional Amounts) in any provision hereof or thereof shall not be construed as excluding reference to Additional Interest (or Additional Amounts) in those provisions hereof or thereof where such express mention is not made.

------

In the event that Additional Interest actually paid with respect to the Notes pursuant to the preceding paragraphs is 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 such references to the Stated Maturity of the principal in respect of any Note shall be deemed to mean and include the Redemption Date with respect to any such Redemption Price), and all such references to principal, premium, interest or Additional Interest (or Additional Amounts) shall be deemed to mean and include any amount payable in respect hereof pursuant to Section 1009 of the Base Indenture.

The Company may, at its option, redeem the Notes as provided below in the following clauses (i) and (ii) upon the terms set forth in Section 1101 of the Base Indenture:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(i)&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; The Company may, at its option, redeem the Notes upon not less than 30 nor more than 60 days' notice, in whole but not in part, at a Redemption Price equal to the sum of (A) 100% of the principal amount of the Notes being redeemed, (B) any accrued and unpaid interest thereon to the Redemption Date and (C) any Additional Interest which would otherwise be payable thereon up to but not including the Redemption Date, solely if, as a result of any amendment to, or change in, the laws (or any rules or regulations thereunder) of Mexico or any political subdivision or taxing authority thereof or therein affecting taxation or any amendment to or change in an official interpretation or application of such laws, rules or regulations, which amendment to or change in such laws, rules or regulations becomes effective on or after February 1, 2024, the Company would be obligated, after taking such measures as the Company may consider reasonable to avoid such requirement, to pay Additional Interest in excess of the Additional Interest 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 but for such redemption be obligated to pay such Additional Interest 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 Interest remains in effect;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(ii)&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; The Company may, at its option, redeem the Notes upon not less than 10 nor more than 60 days' notice, at any time, or from time to time:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(A) prior to the Par Call Date, in whole or in part, at a Redemption Price equal to the greater of (1)(a) the sum of the present values of the remaining scheduled payments of principal and interest thereon discounted to the Redemption Date (assuming the Notes matured on the Par Call Date) on a semi-annual basis (assuming a 360-day year consisting of twelve 30-day months) at the M Bono Rate plus 15 basis points less (b) interest accrued to the Redemption Date and (2) 100% of the principal amount of the Notes to be redeemed, plus, in the case of (1) and (2), accrued and unpaid interest on the principal amount of the Notes being redeemed to the Redemption Date; and

------

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(B) on or after the Par Call Date, in whole or in part, at a Redemption Price equal to 100% of the principal amount of the Notes being redeemed, plus accrued and unpaid interest on the outstanding principal amount of the Notes being redeemed to the Redemption Date.

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

"<u>Par Call Date</u>" means October 30, 2033 (the date that is three months prior to the stated maturity of the Notes).

"<u>M Bono Rate</u>" 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 M Bono Issue, assuming a price for the Comparable M Bono Issue (expressed as a percentage of its principal amount) equal to the Comparable M Bono Price for such Redemption Date.

"<u>Comparable M Bono Issue</u>" means the Mexican *Bonos de Desarrollo del Gobierno Federal con Tasa de Interés Fija* 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 (assuming, for this purpose, that the Notes matured on the Par Call Date).

"<u>Independent Investment Banker</u>" means one of the Reference M Bono Dealers appointed by us.

"<u>Comparable M Bono Price</u>" means, with respect to any redemption date (1) the average of the Reference M Bono Dealer Quotations for such redemption date, after excluding the highest and lowest such Reference M Bono Dealer Quotation or (2) if we obtain fewer than four such Reference M Bono Dealer Quotations, the average of all such quotations.

"<u>Reference M Bono Dealer</u>" means (i) Casa de Bolsa BBVA México, S.A. de C.V., Grupo Financiero BBVA México; (ii) Citibanamex Casa de Bolsa, S.A. de C.V., Casa de Bolsa, Integrante del Grupo Financiero Citibanamex; (iii) Goldman Sachs México, Casa de Bolsa, S.A. de C.V.; (iv) HSBC Casa de Bolsa, S.A. de C.V., Grupo Financiero HSBC; (v) J.P.

"<u>Reference M Bono Dealer Quotation</u>" means, with respect to each Reference M Bono Dealer and any redemption date, the average, as determined by us, of the bid and ask prices for the Comparable M Bono Issue (expressed in each case as a percentage of its principal amount) quoted in writing to us by such Reference M Bono Dealer at 2:30 p.m. (Mexico City time) on the third business day preceding such redemption date.

The Indenture also contains provisions (1) 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 (2) 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.

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 304 of the Base Indenture), the transfer of this Note is registrable in the Register, upon surrender of this Note for registration of transfer at the corporate trust office of the Trustee or agency of the Company in any place where the principal of and any 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 and the 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 Ps.2,000,000 and integral multiples of Ps.10,000 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.

No service charge shall be made for any such registration of transfer or exchange, but the Company or the Trustee or the Paying Agent 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 Trustee and any agent of the Company or of the Trustee may treat the Person in whose name this Note is registered as the owner hereof for all purposes, whether or not this Note is overdue, and neither the Company, the Trustee nor any such agent shall be affected by notice to the contrary.

*Form of Reverse of Note*.

This Note is one of a duly authorized issue of securities of the Company (the "<u>Notes</u>"), issued under the Indenture, dated as of October 1, 2018 (the "<u>Base Indenture</u>"), among the Company, Citibank, N.A., as Trustee (the "<u>Trustee</u>," which term includes any successor trustee under the Indenture), Registrar and Transfer Agent, and Citibank, N.A., London Branch, as Paying Agent (in such capacity, the "<u>Paying Agent</u>"), as supplemented by the Seventh Supplemental Indenture, dated as of February 1, 2024, among the Company, the Trustee and Citibank, N.A., London Branch, as Paying Agent, Authenticating Agent (in such capacity, the Authenticating Agent) and London Transfer Agent (in such capacity, the "<u>London Transfer Agent</u>") (the "<u>Seventh Supplemental Indenture</u>"), as supplemented by (a) the Additional Notes Supplement to the Seventh Supplemental Indenture, dated as of July 8, 2025 (the "<u>Existing Additional Notes Supplement</u>"), and (b) the Additional Notes Supplement to the Seventh Supplemental Indenture dated as of November 25, 2025 (the "<u>Additional Notes Supplement</u>" and, together with the Base Indenture, the Seventh Supplemental Indenture and the Existing Additional Notes Supplement, the "<u>Indenture</u>"), and reference is hereby made to the Indenture for a statement of the respective rights, limitations of rights, indemnities, duties and immunities thereunder of the Company, the Trustee, the Paying Agent, each Transfer Agent, the Authenticating Agent and the Holders of the Notes and of the terms upon which the Notes are, and are to be, authenticated and delivered. The terms, conditions and provisions of this Note are those stated in the Indenture (including those made a part of the Indenture by reference to the Trust Indenture Act) and those set forth in this Note. 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, the date on which interest will 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 the 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, premium, if any, 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 ("<u>Mexican Taxes</u>"). In the event of any withholding or deduction for any Mexican Taxes, the Company shall pay such additional interest ("<u>Additional Interest</u>") 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 Interest) been required, except that no such Additional Interest 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 the Company has given the Holders at least 30 days' notice prior to the first payment date with respect to which such certification, identification or reporting requirement is required, to the effect that Holders will be required to provide such information and identification;

(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 Interest on presenting such Note for payment on any date during such 15-day period;

<br> (iii) of any estate, inheritance, gift or other similar taxes, assessments or other governmental charges imposed with respect to such Note;

<br> (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 Interest had such beneficiary, settlor, member or beneficial owner been the Holder of such Note; and

------

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

For purposes of the provisions described in Clause (i) above, the term "Holder" of any 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 Interest 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 (i) the provision of the information, documentation or other evidence described in such Clause (i)(B) is expressly required by the applicable Mexican laws and regulations (including Article 166, Section II, subsection (a) of the Mexican Income Tax Law or any substantially similar successor provision, whether included in any law or regulation), (ii) the Company cannot obtain such information, documentation or other evidence necessary to comply with the applicable Mexican laws and regulations on its own through reasonable diligence and (iii) the Company otherwise would meet the requirements for application of the applicable Mexican laws and regulations (including Article 166, Section II, subsection (a) of the Mexican Income Tax Law or any substantially similar successor provision, whether included in any law or regulation). In addition, such Clause (i)(B) shall not be construed 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.

Neither the Trustee nor the Paying Agent shall have any duty to calculate the Additional Interest nor shall they have any duty to review or verify the Company´s calculations of the Additional Interest.

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 Interest. 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 issuance of the Notes.

All references herein and in the Indenture to principal, premium, if any, interest or any other amount payable in respect of any Note shall be deemed to include all Additional Interest, 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 Interest (or Additional Amounts) in any provision hereof or thereof shall not be construed as excluding reference to Additional Interest (or Additional Amounts) in those provisions hereof or thereof where such express mention is not made.

------

In the event that Additional Interest actually paid with respect to the Notes pursuant to the preceding paragraphs is 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 such references to the Stated Maturity of the principal in respect of any Note shall be deemed to mean and include the Redemption Date with respect to any such Redemption Price), and all such references to principal, premium, interest or Additional Interest (or Additional Amounts) shall be deemed to mean and include any amount payable in respect hereof pursuant to Section 1009 of the Base Indenture.

The Company may, at its option, redeem the Notes as provided below in the following clauses (i) and (ii) upon the terms set forth in Section 1101 of the Base Indenture:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(i)&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; The Company may, at its option, redeem the Notes upon not less than 30 nor more than 60 days' notice, in whole but not in part, at a Redemption Price equal to the sum of (A) 100% of the principal amount of the Notes being redeemed, (B) any accrued and unpaid interest thereon to the Redemption Date and (C) any Additional Interest which would otherwise be payable thereon up to but not including the Redemption Date, solely if, as a result of any amendment to, or change in, the laws (or any rules or regulations thereunder) of Mexico or any political subdivision or taxing authority thereof or therein affecting taxation or any amendment to or change in an official interpretation or application of such laws, rules or regulations, which amendment to or change in such laws, rules or regulations becomes effective on or after February 1, 2024, the Company would be obligated, after taking such measures as the Company may consider reasonable to avoid such requirement, to pay Additional Interest in excess of the Additional Interest 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 but for such redemption be obligated to pay such Additional Interest 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 Interest remains in effect;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(ii)&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; The Company may, at its option, redeem the Notes upon not less than 10 nor more than 60 days' notice, at any time, or from time to time:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(B) on or after the Par Call Date, in whole or in part, at a Redemption Price equal to 100% of the principal amount of the Notes being redeemed, plus accrued and unpaid interest on the outstanding principal amount of the Notes being redeemed to the Redemption Date.

"<u>M Bono Rate</u>" 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 M Bono Issue, assuming a price for the Comparable M Bono Issue (expressed as a percentage of its principal amount) equal to the Comparable M Bono Price for such Redemption Date.

"<u>Independent Investment Banker</u>" means one of the Reference M Bono Dealers appointed by us.

"<u>Comparable M Bono Price</u>" means, with respect to any redemption date (1) the average of the Reference M Bono Dealer Quotations for such redemption date, after excluding the highest and lowest such Reference M Bono Dealer Quotation or (2) if we obtain fewer than four such Reference M Bono Dealer Quotations, the average of all such quotations.

------

"<u>Reference M Bono Dealer Quotation</u>" means, with respect to each Reference M Bono Dealer and any redemption date, the average, as determined by us, of the bid and ask prices for the Comparable M Bono Issue (expressed in each case as a percentage of its principal amount) quoted in writing to us by such Reference M Bono Dealer at 2:30 p.m. (Mexico City time) on the third business day preceding such redemption date.

The Indenture permits, with certain exceptions as therein provided, the amendment thereof and the modification of the rights and obligations of the Company, on the one hand, and the rights of the Holders of the Notes, on the other hand, to be affected under the Indenture at any time by the Company and the Trustee with the consent of the Holders of a majority in principal amount of the Notes at the time Outstanding. The Indenture also contains provisions (1) 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 (2) 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.

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.

This Note is one of a duly authorized issue of securities of the Company (the "<u>Notes</u>"), issued under the Indenture, dated as of October 1, 2018 (the "<u>Base Indenture</u>"), among the Company, Citibank, N.A., as Trustee (the "<u>Trustee</u>," which term includes any successor trustee under the Indenture), Registrar and Transfer Agent, and Citibank, N.A., London Branch, as Paying Agent (in such capacity, the "<u>Paying Agent</u>"), as supplemented by the Eighth Supplemental Indenture, dated as of March 27, 2024, among the Company, the Trustee and Citibank, N.A., London Branch, as Paying Agent, Authenticating Agent (in such capacity, the Authenticating Agent) and London Transfer Agent (in such capacity, the "<u>London Transfer Agent</u>") (the "<u>Eighth Supplemental Indenture</u>"), as supplemented by (a) the Additional Notes Supplement, dated as of July 8, 2025 (the "<u>Existing Additional Notes Supplement</u>"), and (b) the Existing Additional Notes Supplement to the Eighth Supplemental Indenture dated as of November 25, 2025 (the "<u>Additional Notes Supplement</u>" and, together with the Base Indenture, the Eighth Supplemental Indenture and the Existing Additional Notes Supplement, the "<u>Indenture</u>"), and reference is hereby made to the Indenture for a statement of the respective rights, limitations of rights, indemnities, duties and immunities thereunder of the Company, the Trustee, the Paying Agent, each Transfer Agent, the Authenticating Agent and the Holders of the Notes and of the terms upon which the Notes are, and are to be, authenticated and delivered. The terms, conditions and provisions of this Note are those stated in the Indenture (including those made a part of the Indenture by reference to the Trust Indenture Act) and those set forth in this Note. 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, the date on which interest will 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 the 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, premium, if any, 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 ("<u>Mexican Taxes</u>"). In the event of any withholding or deduction for any Mexican Taxes, the Company shall pay such additional interest ("<u>Additional Interest</u>") 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 Interest) been required, except that no such Additional Interest 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 the Company has given the Holders at least 30 days' notice prior to the first payment date with respect to which such certification, identification or reporting requirement is required, to the effect that Holders will be required to provide such information and identification;

(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 Interest on presenting such Note for payment on any date during such 15-day period;

<br> (iii) of any estate, inheritance, gift or other similar taxes, assessments or other governmental charges imposed with respect to such Note;

<br> (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 Interest had such beneficiary, settlor, member or beneficial owner been the Holder of such Note; and

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

------

For purposes of the provisions described in Clause (i) above, the term "Holder" of any 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 Interest 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 (i) the provision of the information, documentation or other evidence described in such Clause (i)(B) is expressly required by the applicable Mexican laws and regulations (including Article 166, Section II, subsection (a) of the Mexican Income Tax Law or any substantially similar successor provision, whether included in any law or regulation), (ii) the Company cannot obtain such information, documentation or other evidence necessary to comply with the applicable Mexican laws and regulations on its own through reasonable diligence and (iii) the Company otherwise would meet the requirements for application of the applicable Mexican laws and regulations (including Article 166, Section II, subsection (a) of the Mexican Income Tax Law or any substantially similar successor provision, whether included in any law or regulation). In addition, such Clause (i)(B) shall not be construed 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.

Neither the Trustee nor the Paying Agent shall have any duty to calculate the Additional Interest nor shall they have any duty to review or verify the Company´s calculations of the Additional Interest.

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 Interest. 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 issuance of the Notes.

All references herein and in the Indenture to principal, premium, if any, interest or any other amount payable in respect of any Note shall be deemed to include all Additional Interest, 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 Interest (or Additional Amounts) in any provision hereof or thereof shall not be construed as excluding reference to Additional Interest (or Additional Amounts) in those provisions hereof or thereof where such express mention is not made.

In the event that Additional Interest actually paid with respect to the Notes pursuant to the preceding paragraphs is 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 such references to the Stated Maturity of the principal in respect of any Note shall be deemed to mean and include the Redemption Date with respect to any such Redemption Price), and all such references to principal, premium, interest or Additional Interest (or Additional Amounts) shall be deemed to mean and include any amount payable in respect hereof pursuant to Section 1009 of the Base Indenture.

The Company may, at its option, redeem the Notes as provided below in the following clauses (i) and (ii) upon the terms set forth in Section 1101 of the Base Indenture:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(i)&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; The Company may, at its option, redeem the Notes upon not less than 30 nor more than 60 days' notice, in whole but not in part, at a Redemption Price equal to the sum of (A) 100% of the principal amount of the Notes being redeemed, (B) any accrued and unpaid interest thereon to the Redemption Date and (C) any Additional Interest which would otherwise be payable thereon up to but not including the Redemption Date, solely if, as a result of any amendment to, or change in, the laws (or any rules or regulations thereunder) of Mexico or any political subdivision or taxing authority thereof or therein affecting taxation or any amendment to or change in an official interpretation or application of such laws, rules or regulations, which amendment to or change in such laws, rules or regulations becomes effective on or after March 27, 2024, the Company would be obligated, after taking such measures as the Company may consider reasonable to avoid such requirement, to pay Additional Interest in excess of the Additional Interest 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 but for such redemption be obligated to pay such Additional Interest 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 Interest remains in effect;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(ii)&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; The Company may, at its option, redeem the Notes upon not less than 10 nor more than 60 days' notice, at any time, or from time to time:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(A) prior to the Par Call Date, in whole or in part, at a Redemption Price equal to the greater of (1)(a) the sum of the present values of the remaining scheduled payments of principal and interest thereon discounted to the Redemption Date (assuming the Notes matured on the Par Call Date) on a semi-annual basis (assuming a 360-day year consisting of twelve 30-day months) at the M Bono Rate plus 15 basis points less (b) interest accrued to the Redemption Date and (2) 100% of the principal amount of the Notes to be redeemed, plus, in the case of (1) and (2), accrued and unpaid interest on the principal amount of the Notes being redeemed to the Redemption Date; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(B) on or after the Par Call Date, in whole or in part, at a Redemption Price equal to 100% of the principal amount of the Notes being redeemed, plus accrued and unpaid interest on the outstanding principal amount of the Notes being redeemed to the Redemption Date.

"<u>M Bono Rate</u>" 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 M Bono Issue, assuming a price for the Comparable M Bono Issue (expressed as a percentage of its principal amount) equal to the Comparable M Bono Price for such Redemption Date.

"<u>Comparable M Bono Issue</u>" means the Mexican *Bonos de Desarrollo del Gobierno Federal con Tasa de Interés Fija* 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 (assuming, for this purpose, that the Notes matured on the Par Call Date).

"<u>Independent Investment Banker</u>" means one of the Reference M Bono Dealers appointed by us.

"<u>Comparable M Bono Price</u>" means, with respect to any redemption date (1) the average of the Reference M Bono Dealer Quotations for such redemption date, after excluding the highest and lowest such Reference M Bono Dealer Quotation or (2) if we obtain fewer than four such Reference M Bono Dealer Quotations, the average of all such quotations.

"<u>Reference M Bono Dealer Quotation</u>" means, with respect to each Reference M Bono Dealer and any redemption date, the average, as determined by us, of the bid and ask prices for the Comparable M Bono Issue (expressed in each case as a percentage of its principal amount) quoted in writing to us by such Reference M Bono Dealer at 2:30 p.m. (Mexico City time) on the third business day preceding such redemption date.

The Indenture permits, with certain exceptions as therein provided, the amendment thereof and the modification of the rights and obligations of the Company, on the one hand, and the rights of the Holders of the Notes, on the other hand, to be affected under the Indenture at any time by the Company and the Trustee with the consent of the Holders of a majority in principal amount of the Notes at the time Outstanding. The Indenture also contains provisions (1) 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 (2) 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.

------

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 and/or security 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 and/or security. 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 304 of the Base Indenture), the transfer of this Note is registrable in the Register, upon surrender of this Note for registration of transfer at the corporate trust office of the Trustee or agency of the Company in any place where the principal of and any 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 and the 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.

*Form of Reverse of Note*.

This Note is one of a duly authorized issue of securities of the Company (the "<u>Notes</u>"), issued under the Indenture, dated as of October 1, 2018 (the "<u>Base Indenture</u>"), among the Company, Citibank, N.A., as Trustee (the "<u>Trustee</u>," which term includes any successor trustee under the Indenture), Registrar and Transfer Agent, and Citibank, N.A., London Branch, as Paying Agent (in such capacity, the "<u>Paying Agent</u>"), as supplemented by the Eighth Supplemental Indenture, dated as of March 27, 2024, among the Company, the Trustee and Citibank, N.A., London Branch, as Paying Agent, Authenticating Agent (in such capacity, the Authenticating Agent) and London Transfer Agent (in such capacity, the "<u>London Transfer Agent</u>") (the "<u>Eighth Supplemental Indenture</u>"), as supplemented by (a) the Additional Notes Supplement, dated as of July 8, 2025 (the "<u>Existing Additional Notes Supplement</u>"), and (b) the Existing Additional Notes Supplement to the Eighth Supplemental Indenture dated as of November 25, 2025 (the "<u>Additional Notes Supplement</u>" and, together with the Base Indenture, the Eighth Supplemental Indenture and the Existing Additional Notes Supplement, the "<u>Indenture</u>"), and reference is hereby made to the Indenture for a statement of the respective rights, limitations of rights, indemnities, duties and immunities thereunder of the Company, the Trustee, the Paying Agent, each Transfer Agent, the Authenticating Agent and the Holders of the Notes and of the terms upon which the Notes are, and are to be, authenticated and delivered. The terms, conditions and provisions of this Note are those stated in the Indenture (including those made a part of the Indenture by reference to the Trust Indenture Act) and those set forth in this Note. 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, the date on which interest will 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 the 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, premium, if any, 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 ("<u>Mexican Taxes</u>"). In the event of any withholding or deduction for any Mexican Taxes, the Company shall pay such additional interest ("<u>Additional Interest</u>") 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 Interest) been required, except that no such Additional Interest 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 the Company has given the Holders at least 30 days' notice prior to the first payment date with respect to which such certification, identification or reporting requirement is required, to the effect that Holders will be required to provide such information and identification;

(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 Interest on presenting such Note for payment on any date during such 15-day period;

<br> (iii) of any estate, inheritance, gift or other similar taxes, assessments or other governmental charges imposed with respect to such Note;

<br> (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 Interest had such beneficiary, settlor, member or beneficial owner been the Holder of such Note; and

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

------

For purposes of the provisions described in Clause (i) above, the term "Holder" of any 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 Interest 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 (i) the provision of the information, documentation or other evidence described in such Clause (i)(B) is expressly required by the applicable Mexican laws and regulations (including Article 166, Section II, subsection (a) of the Mexican Income Tax Law or any substantially similar successor provision, whether included in any law or regulation), (ii) the Company cannot obtain such information, documentation or other evidence necessary to comply with the applicable Mexican laws and regulations on its own through reasonable diligence and (iii) the Company otherwise would meet the requirements for application of the applicable Mexican laws and regulations (including Article 166, Section II, subsection (a) of the Mexican Income Tax Law or any substantially similar successor provision, whether included in any law or regulation). In addition, such Clause (i)(B) shall not be construed 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.

Neither the Trustee nor the Paying Agent shall have any duty to calculate the Additional Interest nor shall they have any duty to review or verify the Company´s calculations of the Additional Interest.

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 Interest. 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 issuance of the Notes.

All references herein and in the Indenture to principal, premium, if any, interest or any other amount payable in respect of any Note shall be deemed to include all Additional Interest, 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 Interest (or Additional Amounts) in any provision hereof or thereof shall not be construed as excluding reference to Additional Interest (or Additional Amounts) in those provisions hereof or thereof where such express mention is not made.

In the event that Additional Interest actually paid with respect to the Notes pursuant to the preceding paragraphs is 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 such references to the Stated Maturity of the principal in respect of any Note shall be deemed to mean and include the Redemption Date with respect to any such Redemption Price), and all such references to principal, premium, interest or Additional Interest (or Additional Amounts) shall be deemed to mean and include any amount payable in respect hereof pursuant to Section 1009 of the Base Indenture.

The Company may, at its option, redeem the Notes as provided below in the following clauses (i) and (ii) upon the terms set forth in Section 1101 of the Base Indenture:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(i)&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; The Company may, at its option, redeem the Notes upon not less than 30 nor more than 60 days' notice, in whole but not in part, at a Redemption Price equal to the sum of (A) 100% of the principal amount of the Notes being redeemed, (B) any accrued and unpaid interest thereon to the Redemption Date and (C) any Additional Interest which would otherwise be payable thereon up to but not including the Redemption Date, solely if, as a result of any amendment to, or change in, the laws (or any rules or regulations thereunder) of Mexico or any political subdivision or taxing authority thereof or therein affecting taxation or any amendment to or change in an official interpretation or application of such laws, rules or regulations, which amendment to or change in such laws, rules or regulations becomes effective on or after March 27, 2024, the Company would be obligated, after taking such measures as the Company may consider reasonable to avoid such requirement, to pay Additional Interest in excess of the Additional Interest 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 but for such redemption be obligated to pay such Additional Interest 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 Interest remains in effect;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(ii)&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; The Company may, at its option, redeem the Notes upon not less than 10 nor more than 60 days' notice, at any time, or from time to time:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(A) prior to the Par Call Date, in whole or in part, at a Redemption Price equal to the greater of (1)(a) the sum of the present values of the remaining scheduled payments of principal and interest thereon discounted to the Redemption Date (assuming the Notes matured on the Par Call Date) on a semi-annual basis (assuming a 360-day year consisting of twelve 30-day months) at the M Bono Rate plus 15 basis points less (b) interest accrued to the Redemption Date and (2) 100% of the principal amount of the Notes to be redeemed, plus, in the case of (1) and (2), accrued and unpaid interest on the principal amount of the Notes being redeemed to the Redemption Date; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(B) on or after the Par Call Date, in whole or in part, at a Redemption Price equal to 100% of the principal amount of the Notes being redeemed, plus accrued and unpaid interest on the outstanding principal amount of the Notes being redeemed to the Redemption Date.

------

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

"<u>Par Call Date</u>" means December 22, 2028 (the date that is one month prior to the stated maturity of the Notes).

"<u>M Bono Rate</u>" 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 M Bono Issue, assuming a price for the Comparable M Bono Issue (expressed as a percentage of its principal amount) equal to the Comparable M Bono Price for such Redemption Date.

"<u>Comparable M Bono Issue</u>" means the Mexican *Bonos de Desarrollo del Gobierno Federal con Tasa de Interés Fija* 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 (assuming, for this purpose, that the Notes matured on the Par Call Date).

"<u>Independent Investment Banker</u>" means one of the Reference M Bono Dealers appointed by us.

"<u>Comparable M Bono Price</u>" means, with respect to any redemption date (1) the average of the Reference M Bono Dealer Quotations for such redemption date, after excluding the highest and lowest such Reference M Bono Dealer Quotation or (2) if we obtain fewer than four such Reference M Bono Dealer Quotations, the average of all such quotations.

"<u>Reference M Bono Dealer</u>" means (i) Casa de Bolsa BBVA México, S.A. de C.V., Grupo Financiero BBVA México; (ii) Citibanamex Casa de Bolsa, S.A. de C.V., Casa de Bolsa, Integrante del Grupo Financiero Citibanamex; (iii) Goldman Sachs México, Casa de Bolsa, S.A. de C.V.; (iv) HSBC Casa de Bolsa, S.A. de C.V., Grupo Financiero HSBC; (v) J.P.

"<u>Reference M Bono Dealer Quotation</u>" means, with respect to each Reference M Bono Dealer and any redemption date, the average, as determined by us, of the bid and ask prices for the Comparable M Bono Issue (expressed in each case as a percentage of its principal amount) quoted in writing to us by such Reference M Bono Dealer at 2:30 p.m. (Mexico City time) on the third business day preceding such redemption date.

The Indenture permits, with certain exceptions as therein provided, the amendment thereof and the modification of the rights and obligations of the Company, on the one hand, and the rights of the Holders of the Notes, on the other hand, to be affected under the Indenture at any time by the Company and the Trustee with the consent of the Holders of a majority in principal amount of the Notes at the time Outstanding. The Indenture also contains provisions (1) 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 (2) 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 hereof 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 and/or security 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 and/or security. 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 304 of the Base Indenture), the transfer of this Note is registrable in the Register, upon surrender of this Note for registration of transfer at the corporate trust office of the Trustee or agency of the Company in any place where the principal of and any 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 and the 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.

Mexico

Ladies and Gentlemen:

We have acted as special United States counsel to América Móvil, S.A.B. de C.V. (the "<u>Company</u>"), a corporation (*sociedad anónima bursátil de capital variable*) organized under the laws of the United Mexican States, in connection with the Company's offering pursuant to a registration statement on Form F-3 (File No. 333-287731) (the "<u>Registration Statement</u>") of (i) Ps.3,500, 0000,000 aggregate principal amount of its 10.125% Senior Notes due 2029 (the "<u>2029 Notes</u>") and (ii) Ps.6,500,000,000 aggregate principal amount of its 10.300% Senior Notes due 2034 (the "<u>2034 Notes</u>," and together with the 2029 Notes, the "<u>Notes</u>") to be issued under an indenture, dated as of October 1, 2018 (the "<u>Base Indenture</u>"), among the Company, Citibank, N.A., as trustee (the "<u>Trustee</u>"), registrar and transfer agent, and Citibank, N.A., London Branch, as paying agent (the "<u>Paying Agent</u>"), as supplemented by (i) with respect to the 2029 Notes, the Eighth Supplemental Indenture, dated as of March 27, 2024 (the "<u>Eighth Supplemental Indenture</u>"), as further amended and supplemented by (a) the Additional Notes Supplement to the Eighth Supplemental Indenture, dated as of July 8, 2025 (the "<u>2029 Existing Additional Notes Supplement</u>"), and (b) the Additional Notes Supplement to the Eighth Supplemental Indenture dated as of November 25, 2025 (the "<u>2029 Additional Notes Supplement</u>") and (ii) with respect to the 2034 Notes, the Seventh Supplemental Indenture, dated as of February 1, 2024 (the "<u>Seventh Supplemental Indenture</u>," together with the Eighth Supplemental Indenture, the "<u>Supplemental Indentures</u>"), as further amended and supplemented by (a) the Additional Notes Supplement to the Seventh Supplemental Indenture, dated as of July 8, 2025 (the "<u>2034 Existing Additional Notes Supplement</u>"), and (b) the Additional Notes Supplement to the Seventh Supplemental Indenture dated as of November 25, 2025 (the "<u>2034 Additional Notes Supplement</u>," together with the 2029 Additional Notes Supplement, the "<u>Additional Notes Supplements</u>"), each among the Company, the Trustee and the Paying Agent.

In arriving at the opinion expressed below, we have reviewed the Registration Statement, including the Base Indenture, which is filed as an exhibit thereto, and we have reviewed the Supplemental Indentures, the Additional Notes Supplements and the global notes representing the Notes, as executed by the Company and authenticated by the Trustee. In addition, we have reviewed the originals or copies certified or otherwise identified to our satisfaction of all such corporate records of the Company and such other documents, and we have made such investigations of law, as we have deemed appropriate as a basis for the opinion expressed below.

------

In rendering the opinion expressed below, we have assumed the authenticity of all documents submitted to us as originals and the conformity to the originals of all documents submitted to us as copies. In addition, we have assumed and have not verified the accuracy as to factual matters of each document we have reviewed.

Based on the foregoing, and subject to the further assumptions and qualifications set forth below, it is our opinion that the Notes are the valid, binding and enforceable obligations of the Company.

Insofar as the foregoing opinion relates to the validity, binding effect or enforceability of any agreement or obligation of the Company, (a) we have assumed that the Company and each other party to such agreement or obligation has satisfied those legal requirements that are applicable to it to the extent necessary to make such agreement or obligation enforceable against it (except that no such assumption is made as to the Company regarding matters of the federal law of the United States of America or the law of the State of New York that in our experience normally would be applicable to general business entities with respect to such agreement or obligation), (b) such opinion is subject to applicable bankruptcy, insolvency and similar laws affecting creditors' rights generally, to general principles of equity and to the effect of judicial application of foreign laws or foreign governmental actions affecting creditors' rights.

We express no opinion as to the subject matter jurisdiction of any United States federal court to adjudicate any action relating to the Base Indenture, the Supplemental Indentures and the Additional Notes Supplements or the Notes where jurisdiction based on diversity of citizenship under 28 U.S.C. §1332 does not exist.

We note that (a) the designation in Section 115 of the Base Indenture of the U.S. federal courts located in the Borough of Manhattan, The City of New York as the venue for actions or proceedings arising out of or relating to the Base Indenture or the Notes, the designation in Section 301 of each of the Supplemental Indentures of the U.S. federal courts located in the Borough of Manhattan, The City of New York as the venue for actions or proceedings arising out of or relating to the Supplemental Indentures, are (notwithstanding the waivers in Section 115 of the Base Indenture and Section 301 of each of the Supplemental Indentures) subject to the power of such courts to transfer actions pursuant to 28 U.S.C. §1404(a) or to dismiss such actions or proceedings on the grounds that such a federal court is an inconvenient forum for such an action or proceeding and (b) the enforceability in the United States of the waiver in Section 115 of the Base Indenture and Section 301 of each of the Supplemental Indentures by the Company of any immunity from jurisdiction or to service of process is subject to the limitations imposed by the United States Foreign Sovereign Immunities Act of 1976.

We note that by statute New York provides that a judgment or decree rendered in a currency other than the currency of the United States shall be converted into U.S. dollars at a rate of exchange prevailing on the date of entry of the judgment or decree. There is no corresponding U.S. federal statute and no controlling U.S. federal court decision on this issue. Accordingly, we express no opinion as to whether a U.S. federal court would award a judgment in a currency other than U.S. dollars or, if it did so, whether it would order the conversion of the judgment into U.S. dollars.

------

We express no opinion as to the enforceability of the judgment currency indemnities in Section 1010 of the Base Indenture.

The foregoing opinion is limited to the federal law of the United States of America and the law of the State of New York.

We hereby consent to the incorporation by reference of this opinion in the Registration Statement and to the reference to this firm in the prospectus constituting a part of the Registration Statement under the heading "*Validity of MXN Notes*" and in any prospectus supplements related thereto under the heading "*Validity of Notes*" as counsel for the Company who have passed on the validity of the Notes being registered by the Registration Statement. In giving such consent, we do not thereby admit that we are within the category of persons whose consent is required under Section 7 of the Securities Act or the rules and regulations of the Commission thereunder. We assume no obligation to advise you or any other person, or to make any investigations, as to any legal developments or factual matters arising subsequent to the date hereof that might affect the opinions expressed herein.

Ladies and Gentlemen:

We have acted as special Mexican counsel to América Móvil, S.A.B. de C.V. (the "<u>Company</u>"), a corporation (*sociedad anónima bursátil de capital variable*) organized under the laws of the United Mexican States ("<u>Mexico</u>"), in connection with the Company's offering pursuant to a registration statement on Form F-3 (No. 333-287731) (the "<u>Registration Statement</u>") (i) of Ps. 6,500,000,000.00 aggregate principal amount of its 10.300% Senior Notes due 2034 (the "<u>2034 Notes</u>"); and (ii) of Ps. 3,500,000,000.00 aggregate principal amount of its 10.125% Senior Notes due 2029 (the "<u>2029 Notes</u>", and, together with the 2034 Notes, the "<u>Notes</u>") to be issued under an indenture, dated as of October 1, 2018 (the "<u>Base Indenture</u>") among the Company, Citibank, N.A., as trustee (the "<u>Trustee</u>"), registrar and transfer agent, and Citibank, N.A., London Branch, as paying agent (the "<u>Paying Agent</u>"), as amended and supplemented by (i) the seventh supplemental indenture dated as of February 1, 2024, as further supplemented by an additional notes supplement, dated as of November 25, 2025, relating to the 2034 Notes (the "<u>Additional 2034 Notes Supplement</u>"); and (ii) the eighth supplemental indenture dated as of March 27, 2024, as further supplemented by an additional notes supplement, dated as of November 25, 2025, relating to the 2029 Notes (the "<u>Additional 2029 Notes Supplement</u>" and, together with the Additional 2034 Notes Supplement, the "<u>Supplemental Indentures</u>" and, together with the "Base Indenture, the "<u>Indenture</u>") between the Company, the Trustee and the Paying Agent.

The Notes have been concurrently offered and sold in Mexico pursuant to a public offering in Mexico. Furthermore, (i) the 2034 Notes constitute a further issuance by the Company of its 10.300% Senior Notes due 2034, which were originally issued in an aggregate principal amount of Ps.20,000,000,000.00 on February 1, 2024 and in the aggregate principal amount of Ps.3,500,000,000 on July 8, 2025; and (ii) the 2029 Notes constitute a further issuance by the Company of its 10.125% Senior Notes due 2029, which were originally issued in an aggregate principal amount of Ps.17,500,000,000.00 on March 27, 2024 and in the aggregate principal amount of Ps.6,000,000,000 on July 8, 2025.

For purposes of rendering this opinion, we have examined (i) the Registration Statement, including the Base Indenture, which is incorporated therein as an exhibit, (ii) the Supplemental Indentures, (iii) the global notes representing the Notes, (iv) the *estatutos sociales* (by-laws) of the Company, and (v) the corresponding corporate actions, and such other documents, records and matters of law, as we have deemed necessary, and have assumed the genuineness of all signatures and the authenticity of all documents submitted to us as originals and the conformity with the originals of all documents submitted to us as copies. In addition, we have assumed and have not verified the accuracy as to factual matters of each document we have reviewed.

Based on the foregoing, and subject to the further assumptions and qualifications set forth below, it is our opinion that:

<br> 1. The Company is duly incorporated and validly existing under the laws of Mexico.

<br> 2. The Company has the corporate power to, and all necessary corporate action has been taken to, execute and deliver the Notes.

<br> 3. The Notes are the valid, binding and enforceable obligations of the Company, entitled to the benefits of the Indenture, respectively.

This opinion is subject to the following qualifications:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a)&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; Enforcement may be limited or affected by *concurso mercantil*, bankruptcy, insolvency, liquidation, reorganization, moratorium and other similar laws of general application relating to or affecting the rights of creditors generally; among other things, interest on principal will not accrue after declaration of bankruptcy, and the obligations of the Company in foreign currency shall be converted into Mexican currency at the rate of exchange published in the *Diario Oficial de la Federación* (Official Daily Gazette of the Federation) by *Banco de México* (the Central Bank of Mexico) in force on the date the declaration of *concurso mercantil* is made; such Mexican currency obligations shall then be converted into "*Unidades de Inversión*" or "*UDIS*" (inflation indexed units) at the rate of conversion published by *Banco de México* for such date, because the Notes are unsecured (*quirografarias*) and therefore no senior status is granted thereto under Mexican law; also pursuant to the laws of Mexico, labor claims, claims of tax authorities for unpaid taxes will have priority over claims of the holders of the Notes;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b)&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; We note that the payment of interest on interest may not be enforceable under Mexican law; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(c)&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; We note that Article 1093 of the Mexican Commerce Code (*Código de Comercio*), provides that for a choice of jurisdiction to be valid under Mexican Law, such jurisdiction must relate to the domicile of one of the parties to the relevant agreement, to the place where the obligations under such agreement are to be fulfilled, or to the location of the relevant item.

In addition, we have assumed that the Company and the Trustee have satisfied those legal requirements that are applicable to each of them under the law other than federal law of Mexico to the extent necessary to make the Base Indenture, the Supplemental Indentures and the Notes enforceable against each of them.

We express no opinion as to the laws of any jurisdiction other than Mexico and we have assumed that there is nothing in any other law that affects our opinion, which is delivered, based upon Mexican law applicable on the date hereof. In particular, we have made no independent investigation of the laws of the United States of America or any state or other political subdivision thereof or therein as a basis for the opinions stated herein and do not express or imply any opinion on or based on such laws. To the extent that the federal laws of the United States of America and the State of New York are relevant to our opinion set forth above, we have, without making any independent investigation with respect thereto, assumed the accuracy of, and our opinion is subject to the qualifications, assumptions and exceptions set forth in, the opinion, dated today, of Cleary Gottlieb Steen & Hamilton LLP, special United States counsel to the Company.

In rendering the foregoing opinion, we have relied (i) as to factual matters on certificates of directors and executive officers of the Company and (ii) as to matters of United States federal and New York law on the opinion of Cleary Gottlieb Steen & Hamilton LLP, United States counsel for the Company.

We note that Rafael Robles Miaja, a partner of this firm, is currently Pro-Secretary of the Board of Directors of the Company.

We hereby consent to the filing of this opinion as an exhibit to the Registration Statement and to the reference to this firm in the prospectus constituting a part of the Registration Statement under the heading "Validity of Securities" and "Enforceability of Civil Liabilities" and in any prospectus supplements related thereto under the heading "Validity of Notes" as counsel for the Company who have passed on the validity of the notes being registered by the Registration Statement. In giving such consent, we do not thereby admit that we are experts with respect to any part of the Registration Statement, including this exhibit, within the meaning of the term "expert" as used in the U.S. Securities Act of 1933, as amended, or the rules and regulations of the U.S. Securities and Exchange Commission issued thereunder. Cleary Gottlieb Steen & Hamilton LLP may rely upon this opinion in rendering their opinion to you.
