but no later than March 1, 2018. The Exchange Offers will be registered under the Securities Act on the appropriate form and will comply with all applicable rules and regulations under the
Exchange Act. The Issuer further agrees to use its best efforts to commence and complete the Exchange Offers promptly, but no later than April 5, 2018, hold the Exchange Offers open for at least 30 days and issue and deliver Exchange
Securities in exchange for all Registrable Securities that have been properly tendered and not withdrawn on or prior to the expiration of the Exchange Offers. Each holder of Registrable Securities who wishes to exchange such Registrable Securities
for Exchange Securities in, and in accordance with the terms of, the Exchange Offers will be required to make certain customary representations in connection therewith, including representations that such holder is not a Restricted Holder. Upon the
effectiveness of the Exchange Offer Registration Statement, the Issuer shall promptly commence the Exchange Offers, it being the objective of such Exchange Offers that each holder (other than a Restricted Holder) electing to participate in the
Exchange Offers will receive Exchange Securities that are, upon receipt, transferable by each such holder without restriction under the Securities Act and the Exchange Act and without material restrictions under the blue sky or securities laws of a

Securities pursuant to the Exchange Offers and (ii) the Issuer having exchanged, pursuant to the Exchange Offers, Exchange Securities for all Registrable Securities that have been properly tendered and not withdrawn before the expiration of the
Exchange Offers, which shall be on a date that is at least 30 days following the commencement of the Exchange Offers. The Issuer agrees (x) to include in the Exchange Offer Registration Statement a prospectus for use in any resales by any
holder of Exchange Securities that is a broker-dealer and (y) to keep such Exchange Offer Registration Statement effective for a period (the “Resale Period”) beginning when Exchange Securities are first issued in the Exchange Offers
and ending upon the earlier of the expiration of the 180th day after the Exchange Offers have been completed or such time as such broker-dealers no longer own any Registrable Securities. With respect to such Exchange Offer Registration
Statement, such holders shall have the benefit of the rights of indemnification and contribution set forth in Sections 6(a), (c), (d) and (e) hereof. 

(b) If (i) on or prior to the time the Exchange Offers are completed, existing Commission interpretations are changed such
that the debt securities or the related guaranties received by holders other than Restricted Holders in the Exchange Offers for Registrable Securities are not or would not be, upon receipt, transferable by each such holder without restriction under
the Securities Act, (ii) the Exchange Offers have not been completed on or before April 5, 2018 or (iii) any holder notifies the Issuer prior to 20 days after the consummation of the Exchange Offers that (A) based on the
advice of counsel, due to a change in law or Commission policy it may not resell the Exchange Securities acquired by it in the Exchange Offers to the public without delivering a prospectus and the prospectus contained in the Exchange Offer
Registration Statement is not appropriate or available for such resales by such holder or (B) it is a purchaser and owns Registrable Securities acquired directly from the Issuer or an affiliate of the Issuer or (C) on or prior to the
consummation of the Exchange Offers existing laws, regulations and/or applicable Commission interpretations have been changed such that the holders of at least a majority in aggregate principal amount of the Registrable Securities would not be able
to resell the Exchange Securities acquired by them in, and in accordance with the terms of, the Exchange Offers to the public without restriction under the Securities Act and without restriction under applicable blue sky or state securities laws,
the Issuer shall, in lieu of (or, in the case of clause (iii), in addition to) conducting the Exchange Offers contemplated by Section 2(a), use its best efforts to file or cause to be filed under the Securities Act as soon as practicable,
but no later 

  
 5 








 
than the later of March 1, 2018 or 30 days after the time such obligation to file arises (but in no event prior to August 1 or after September 30 of any calendar year), a
“shelf” registration statement providing for the registration of, and the sale on a continuous or delayed basis by the holders of, all of the Registrable Securities, pursuant to Rule 415 or any similar rule that may be adopted by the
Commission (such filing, the “Shelf Registration” and such registration statement, the “Shelf Registration Statement”). 

The Issuer agrees to use its best efforts (x) to cause the Shelf Registration Statement to become or be declared effective
on or prior to 60 days after such filing was required to be made hereunder (but in no event prior to August 1 or after September 30 of any calendar year) and (y) to keep such Shelf Registration Statement continuously effective
for a period of one year (or, if shorter, the period after which Rule 144(d) generally becomes available to non-affiliates of the Issuer) from the effective date of the Shelf Registration Statement (subject to extension pursuant to
Sections 2(d) and 3(h)); provided, however, that if such Shelf Registration Statement has been filed solely at the request of the Purchasers pursuant to clause (iii)(B) of this Section 2(b), the Issuer shall only be
required to use its best efforts to keep such Shelf Registration Statement continuously effective for a period of one year from the date of issuance of the Securities (subject to extension pursuant to Sections 2(d) and 3(h)) or until all
of the Securities covered by the Shelf Registration Statement have been sold pursuant to the Shelf Registration Statement or cease to be outstanding; provided further, however, that no holder shall be entitled to be named as a selling
securityholder in the Shelf Registration Statement or to use the prospectus forming a part thereof for resales of Registrable Securities unless such holder is an Electing Holder. The Issuer further agrees to supplement or make amendments to the
Shelf Registration Statement, as and when required by the rules, regulations or instructions applicable to the registration form used by the Issuer for such Shelf Registration Statement or by the Securities Act or rules and regulations thereunder
for shelf registration, and the Issuer agrees to furnish to each Electing Holder copies of any such supplement or amendment promptly after its being used or promptly following its filing with the Commission. 

(c) If (i) the Exchange Offer Registration Statement (or a Shelf Registration Statement in lieu thereof) is not filed on
or before September 30, 2017, (ii) the Exchange Offer Registration Statement (or a Shelf Registration Statement in lieu thereof) is not declared effective by the Commission on or before March 1, 2018, (iii) the Exchange Offers
are not consummated on or before April 5, 2018, (iv) a Shelf Registration Statement required to be filed is not filed on or before the date specified above for such filing, (v) a Shelf Registration Statement otherwise required to be
filed is not declared effective on or before the date specified above for effectiveness thereof or (vi) a Shelf Registration Statement is declared effective but thereafter, subject to certain exceptions, ceases to be effective or usable
(whether due to a stop order or otherwise) in connection with resales of Registrable Securities during the period specified in Section 2(b) above (each such event referred to in clauses (i) through (vi) above, a
“Registration Default”), then, in the case of a Registration Default referred to in clause (i), (ii) or (iii) above, the interest rate on all Registrable Securities or, in the case of a Registration Default referred to in
clause (iv), (v) or (vi) above, the interest rate on the Registrable Securities to which such Registration Default relates, will increase by 0.25% per annum with respect to each 90-day period that passes until all such
Registration Defaults have been cured, up to a maximum amount of 1.00% per annum (“Additional Interest”); provided, however, that such Additional Interest will cease to accrue at the later of (i) the date on which
the Securities become freely transferable pursuant to Rule 144 and (ii) the date on which the Barclays Capital U.S. Aggregate Bond Index is modified to permit the inclusion of freely transferable securities that have not been registered under
the Securities Act. Upon the cure of any such Registration Default, the interest rate borne by the Registrable Securities shall be reduced thereafter by the full amount of any such increase or increases that resulted from such Registration Default.


  
 6 








 The Issuer shall notify the Trustee within three business days after each
and every date on which an event occurs in respect of which Additional Interest is required to be paid (an “Event Date”). Additional Interest shall be paid by depositing with the Trustee, in trust, for the benefit of the holders, on or
before the applicable semiannual interest payment date, immediately available funds in sums sufficient to pay the Additional Interest then due. The Additional Interest due shall be payable on each interest payment date to the record holder entitled
to receive the interest payment to be paid on such date as set forth in the Indenture. Each obligation to pay Additional Interest shall be deemed to accrue from and including the day following the applicable Event Date. 

(d) Any Exchange Offer Registration Statement pursuant to Section 2(a) and any Shelf Registration Statement pursuant to
Section 2(b) will not be deemed to have become effective unless it has been declared effective by the Commission; provided, however, that, if after it has been declared effective, the offering of Securities pursuant to a Shelf
Registration Statement is subject to any stop order, injunction or other order or requirement of the Commission or any other governmental agency or court, such Registration Statement will be deemed not to have been effective for such Securities
during the period it was so subject, until the offering of such Securities pursuant to such Registration Statement may legally resume. 

In no event shall the Issuer be deemed to be in breach of its obligations under the second paragraph of Section 2(b) nor
shall a Registration Default described in Section 2(c)(vi) be deemed to have occurred (i) as a result of any action required by applicable law which renders the Issuer unable to comply with the Commission disclosure requirements or
(ii) if compliance with its obligations under this Agreement to maintain the effectiveness of, supplement or amend any Registration Statement, upon advice of U.S. counsel to the Issuer, would require additional disclosure of material non-public
information by the Issuer or its subsidiaries as to which, and so long as, the Issuer or its subsidiaries has a bona fide business purpose in preserving its confidentiality; provided, however, that the maximum period of time
during which the Issuer shall be entitled to postpone the effectiveness, supplementing or amending of any Registration Statement pursuant to clause (ii) of this paragraph shall be 45 calendar days; provided, further,
that (x) upon the exercise of its right under clause (ii) of this paragraph to postpone the effectiveness, supplementing or amending of any such Registration Statement, the Issuer shall give the holders prompt written notice of such
exercise and an approximation of the anticipated length of such postponement and (y) after the exercise of its right under clause (ii) of this paragraph to postpone the effectiveness, supplementing or amending of any such Registration
Statement, the Issuer shall not, within six months of the expiration of any such postponement, exercise again its right of postponement under clause (ii) of this paragraph. The holders hereby acknowledge that any notice given by the Issuer
pursuant to this paragraph may constitute material non-public information and that the United States securities laws prohibit any person who has material non-public information about a company from purchasing or selling securities of the company or
from communicating such information to any other person under circumstances in which it is reasonably foreseeable that such person is likely to purchase or sell such securities. 

(e) The Issuer shall take all actions necessary or advisable to cause the Guaranties to be registered under the registration
statement contemplated in Section 2(a) or 2(b) hereof, as applicable. 

  
 7 








 (f) Any reference herein to a registration statement as of any time shall be
deemed to include any document incorporated, or deemed to be incorporated, therein by reference as of such time and any reference herein to any post-effective amendment to a registration statement as of any time shall be deemed to include any
document incorporated, or deemed to be incorporated, therein by reference as of such time.

shall be required to maintain in confidence and not to disclose to any other person any information or records reasonably designated by the Issuer as being confidential, until such time as (A) such information becomes a matter of public record
(whether by virtue of its inclusion in such registration statement or otherwise), (B) such person shall be required so to disclose such information pursuant to a subpoena or order of any court or other governmental agency or body having
jurisdiction over the matter (subject to the requirements of such order, and only after such person shall have given the Issuer prompt prior written notice of such requirement) unless such release is against Mexican law, or (C) in an opinion
addressed to the Issuer of counsel experienced in such matters and approved by the Issuer, such information is required to be set forth in such Shelf Registration Statement or the prospectus included therein or in an amendment to such Shelf
Registration Statement or an amendment or supplement to such prospectus in order that such Shelf Registration Statement, prospectus, amendment or supplement, as the case may be, complies with applicable requirements of the federal securities laws
and the rules and regulations of the Commission and does not contain an untrue statement of a material fact or omit to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading in light of
the circumstances then existing; 
 (vi) promptly notify each of the Electing Holders, any sales or placement agent therefor
and any underwriter thereof (which notification may be made through any managing underwriter that is a representative of such underwriter for such purpose) and confirm such advice in writing, (A) when such Shelf Registration Statement or the

(E) of the receipt by the Issuer of any notification with respect to the suspension of the qualification of the Registrable Securities for sale in any jurisdiction or the initiation or threatening of any proceeding for such purpose, or
(F) if at any time when a prospectus is required to be delivered under the Securities Act, that such Shelf Registration Statement, prospectus, prospectus amendment or supplement or post-effective amendment does not conform in all material
respects to the applicable requirements of the Securities Act and the Trust Indenture Act and the rules and regulations of the Commission thereunder or contains an untrue statement of a material fact or omits to state any material fact required to
be stated therein or necessary to make the statements therein not misleading in light of the circumstances then existing;

supplement or post-effective amendment such information as is required by the applicable rules and regulations of the Commission and as such managing underwriter or underwriters, or such Electing Holder specifies should be included therein relating
to the terms of the sale of such Registrable Securities, including information with respect to the principal amount of Registrable Securities being sold by such Electing Holder or to any underwriters, the name and description of such Electing Holder
or underwriter, the offering price of such Registrable Securities and any discount, commission or other compensation payable in respect thereof, the purchase price being paid therefor by such underwriters and with respect to any other terms of the
offering of the Registrable Securities to be sold by such Electing Holder or to such underwriters; and make all required filings of such prospectus supplement or post-effective amendment promptly after notification of the matters to be incorporated
in such prospectus supplement or post-effective amendment; 
 (ix) furnish to each Electing Holder, therefor, each
underwriter, if any, thereof and the respective counsel referred to in Section 3(d)(iv) an executed copy (or, in the case of an Electing Holder, a conformed copy) of such Shelf Registration Statement, each such amendment and supplement thereto
(in each case including all exhibits thereto (in the case of an Electing Holder of Registrable Securities, upon request) and documents incorporated by reference therein) and such number of copies of such Shelf Registration Statement (excluding
exhibits thereto and documents incorporated by reference therein unless reasonably so requested by such Electing Holder, agent or underwriter, as the case may be) and of the prospectus included in such Shelf Registration Statement (including each
preliminary prospectus and any summary prospectus), in conformity in all material respects with the applicable requirements of the Securities Act and the Trust Indenture Act and the rules and regulations of the Commission thereunder, and such other
documents, as such Electing Holder, agent, if any, and underwriter, if any, may reasonably request in order to facilitate the offering and disposition of the Registrable Securities owned by such Electing Holder, offered or sold by such agent or

prospectus (including such preliminary and summary prospectus) and any amendment or supplement thereto by each such Electing Holder and by any such agent and underwriter, in each case in the form most recently provided to such person by the Issuer,

Statement under such securities laws or blue sky laws of such jurisdictions as any Electing Holder and each underwriter, if any, thereof shall reasonably request, (B) keep such registrations or qualifications in effect and comply


  
 12 








 
with such laws so as to permit the continuance of offers, sales and dealings therein in such jurisdictions during the period the Shelf Registration is required to remain effective under

requirements of this Section 3(d)(x), (2) consent to general service of process in any such jurisdiction or (3) make any changes to its certificate of incorporation or by-laws or any agreement between it and its stockholders; 

(xi) unless any Registrable Securities shall be in book-entry only form, cooperate with the Electing Holders and the managing
underwriters, if any, to facilitate the timely preparation and delivery of certificates representing Registrable Securities to be sold, and, in the case of an underwritten offering, enable such Registrable Securities to be in such denominations and

(xii) enter into one or more underwriting agreements, engagement letters, agency agreements, “best efforts”

or such Electing Holder or Electing Holders and dated the effective date of such Shelf Registration Statement; (C) obtain a “cold comfort” letter or letters from the independent certified public accountants of the Issuer addressed to
the managing underwriters (if any) or, in the event there are no managing underwriters, use reasonable efforts to have such letters addressed to the selling Electing Holders, dated (i) the effective date of such Shelf Registration Statement and
(ii) the effective date of any prospectus supplement to the prospectus included in such Shelf Registration Statement or post-effective amendment to such Shelf Registration Statement which includes unaudited or audited financial statements as of
a date or for a period subsequent to that of the latest such statements included in such prospectus, such letter or letters to be in customary form and covering such matters of the type customarily covered by letters of such type; (D) deliver

as are provided in Section 6 hereof; 
 (xiv) notify in writing each holder of Registrable Securities of any proposal by
the Issuer to amend or waive any provision of this Agreement pursuant to Section 9(g) hereof and of any amendment or waiver effected pursuant thereto, each of which notices shall contain the text of the amendment or waiver proposed or effected,
as the case may be; 
 (xv) in the event that any broker-dealer registered under the Exchange Act shall underwrite any
Registrable Securities or participate as a member of an underwriting syndicate or selling group or “assist in the distribution” (within the meaning of the Conduct Rules (the “Conduct Rules”) of the Financial Industry Regulatory
Authority (“FINRA”, formerly the National Association of Securities Dealers, Inc.) or any successor thereto, as amended from time to time) thereof, whether as a holder of such Registrable Securities or as an underwriter, a placement or
sales agent or a broker or dealer in respect thereof, or otherwise, assist such broker-dealer in complying with the requirements of such Conduct Rules, including by (A) if such Conduct Rules shall so require, engaging a “qualified
independent underwriter” (as defined in such Conduct Rules) to participate in the preparation of the Shelf Registration Statement relating to such Registrable Securities, to exercise usual standards of due diligence in respect thereto and, if
any portion of the offering contemplated by such Shelf Registration Statement is an underwritten offering or is made through a placement or sales agent, to recommend the yield of such Registrable Securities, (B) indemnifying any such qualified
independent underwriter to the extent of the indemnification of underwriters provided in Section 6 hereof (or to such other customary extent as may be requested by such underwriter), and (C) providing such information to such broker-dealer
as may be required in order for such broker-dealer to comply with the requirements of the Conduct Rules; and 
 (xvi) comply
with all applicable rules and regulations of the Commission, and make generally available to its securityholders as soon as practicable but, in any event, not later than 24 months after the effective date of such Shelf Registration Statement,
an earnings statement of the Issuer and its subsidiaries complying with Section 11(a) of the Securities Act (including, at the option of the Issuer, Rule 158 thereunder) (it being understood that the Issuer may satisfy its obligations
under this clause through the filing of its annual report on Form 20-F for the first full fiscal year after such effective date). 

(e) In the event that the Issuer would be required, pursuant to Section 3(d)(vi)(F) above, to notify the Electing Holders
and the managing underwriters, if any, thereof, the Issuer shall without delay prepare and furnish to each of the Electing Holders and to each such underwriter, if any, a reasonable number of copies of a prospectus supplemented or amended so that,
as thereafter delivered to purchasers of Registrable Securities, such prospectus shall conform in all material respects to the applicable requirements of the Securities Act and the Trust Indenture Act


  
 14 








 
and the rules and regulations of the Commission thereunder and shall not contain an untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary
to make the statements therein not misleading in light of the circumstances then existing. Each Electing Holder agrees that upon receipt of any notice from the Issuer pursuant to Section 3(d)(vi)(F) above, such Electing Holder shall forthwith
discontinue the disposition of Registrable Securities pursuant to the Shelf Registration Statement applicable to such Registrable Securities until such Electing Holder shall have received copies of such amended or supplemented prospectus, and if so
directed by the Issuer, such Electing Holder shall deliver to the Issuer (at the Issuer’s expense) all copies, other than permanent file copies, then in such Electing Holder’s possession of the prospectus covering such Registrable
Securities at the time of receipt of such notice. 
 (f) In the event of a Shelf Registration, in addition to the information
required to be provided by each Electing Holder in its Notice Questionnaire, the Issuer may require such Electing Holder to furnish to the Issuer such additional information regarding such Electing Holder and such Electing Holder’s intended
method of distribution of Registrable Securities as the Issuer may, after consulting with counsel, determine is required in order to comply with the Securities Act. Each such Electing Holder agrees to notify the Issuer as promptly as practicable of
any inaccuracy or change in information previously furnished by such Electing Holder to the Issuer or of the occurrence of any event in either case as a result of which any prospectus relating to such Shelf Registration contains or would contain an
untrue statement of a material fact regarding such Electing Holder or such Electing Holder’s intended method of disposition of such Registrable Securities or omits to state any material fact regarding such Electing Holder or such Electing
Holder’s intended method of disposition of such Registrable Securities required to be stated therein or necessary to make the statements therein not misleading in light of the circumstances then existing, and promptly to furnish to the Issuer
any additional information required to correct and update any previously furnished information or required so that such prospectus shall not contain, with respect to such Electing Holder or the disposition of such Registrable Securities, an untrue
statement of a material fact or omit to state a material fact required to be stated therein or necessary to make the statements therein not misleading in light of the circumstances then existing. 

(g) Until the expiration of one year after the Settlement Date, the Issuer will not, and will not permit any of the
Issuer’s direct and indirect subsidiaries or the Guarantors to, resell any of the Securities that have been reacquired by any of them except pursuant to an effective registration statement under the Securities Act. 

(h) In the case of a Shelf Registration Statement or the notification of the Issuer by broker-dealers seeking to sell Exchange
Securities and required to deliver prospectuses that will be utilizing the prospectus contained in the Exchange Offer Registration Statement, each holder agrees that, upon receipt of any notice from the Issuer of (i) the happening of any event
of the kind described in any of clauses (B) – (F) of Section 3(d)(vi) or (ii) the exercise of the Issuer’s right, under clause (ii) of the second paragraph of Section 2(d), to postpone the effectiveness,
supplementing or amending of any such Registration Statement, such holder will forthwith discontinue disposition of Securities pursuant to the applicable Registration Statement until such holder receives the copies of the supplemented or amended
prospectus contemplated by Section 3(c)(iv) or Section 3(e) or until such holder is advised in writing (the “Advice”) by the Issuer that the use of the applicable prospectus may be resumed, and, if so directed by the Issuer, such
holder will deliver to the Issuer (at the Issuer’s expense) all copies in such holder’s possession, other than permanent file copies, of the prospectus covering such Securities current at 

  
 15 








 
the time of receipt of such notice. If the Issuer shall give any such notice to suspend the disposition of any Securities pursuant to a Registration Statement, the Issuer shall use its best
efforts to file a supplement or an amendment to the Registration Statement and, in the case of an amendment, have such amendment declared effective as soon as practicable and shall extend the period during which such Registration Statement shall be
maintained effective pursuant to this Agreement by the number of days in the period from and including the date of the giving of such notice to and including the date when the Issuer shall have made available to the holders (i) copies of the
supplemented or amended prospectus necessary to resume such dispositions or (ii) the Advice. 
 4. Registration Expenses. 

The Issuer agrees, unless otherwise agreed in writing among the Issuer and the Purchasers, to bear and to pay or cause to be paid promptly the
following expenses incident to the Issuer’s performance of or compliance with this Agreement: (a) all Commission and any FINRA registration, filing and review fees and other expenses (except as noted herein) in connection with the
registration of the Securities with the Commission in connection with such registration, filing and review; (b) all fees and expenses in connection with the qualification of the Securities for offering and sale under the state securities and
blue sky laws referred to in Section 3(d)(x) hereof and determination of their eligibility for investment under the laws of such jurisdictions as any managing underwriters or the Electing Holders may designate, including any fees and
disbursements of counsel for the Electing Holders or underwriters in connection with such qualification; (c) fees and expenses of the Trustee under the Indenture, any agent of the Trustee and any counsel for the Trustee and of any collateral

Expenses”). The Purchasers agree to bear and to pay or cause to be paid promptly the following expenses incident to the Purchasers’ compliance with this Agreement: (a) all expenses relating to the preparation, printing, production,
distribution and reproduction of each registration statement required to be filed hereunder, each prospectus included therein or prepared for distribution pursuant hereto, each amendment or supplement to the foregoing (including the cost of
preparing such registration statement, prospectus, amendment or supplement for filing with the Commission in electronic format), the expenses of preparing the Securities for delivery and the expenses of printing or producing any underwriting

the one-time payment of Moody’s quarterly fee for the current quarter, as well as the one-time payment of Moody’s transaction fee, as it relates to the initial sale of the Securities), up to U.S. $50,000; and (e) any fees associated
with listing the Exchange Securities on the Luxembourg Stock Exchange and the consummation by the transactions contemplated by this Agreement in Luxembourg. To the extent that any Registration Expenses are incurred, assumed or paid


  
 16 








 
by any holder of Registrable Securities therefor or underwriter thereof, the Issuer shall reimburse such person for the full amount of the Registration Expenses so incurred, assumed or paid
promptly after receipt of a request therefor. Notwithstanding the foregoing, the holders of the Registrable Securities being registered shall pay all agency fees and commissions and underwriting discounts and commissions attributable to the sale of
such Registrable Securities and the fees and disbursements of any counsel or other advisors or experts retained by such holders (severally or jointly), other than the counsel and experts specifically referred to above. 

5. Representations and Warranties. 

The Issuer represents and warrants to, and agrees with, the Purchasers and each of the holders from time to time of Registrable Securities
that: 
 (a) The compliance by the Issuer with the provisions of this Agreement, and the consummation of the transactions
herein contemplated will not conflict with or result in a breach of any of the terms or provisions of, or constitute a default under, any material agreement or material instrument to which the Issuer or any of the Guarantors is a party or by which
the Issuer or any of the Guarantors is bound or to which any of the property or assets of the Issuer or any of the Guarantors is subject, nor will such action result in any violation of the provisions of the Ley de Petróleos Mexicanos
(the “Petróleos Mexicanos Law”) and related regulations or any other statute or any order, rule or regulation of any court or governmental agency or body having jurisdiction over the Issuer or any of the Guarantors or any of its or
their respective properties; 
 (b) This Agreement has been duly authorized, executed and delivered by the Issuer. 

6. Indemnification. 

(a) Indemnification by the Issuer. The Issuer will indemnify and hold harmless each of the holders of Registrable
Securities included in an Exchange Offer Registration Statement, each of the Electing Holders of Registrable Securities included in a Shelf Registration Statement and each person who participates as an underwriter in any offering or sale of such
Registrable Securities against any losses, claims, damages or liabilities, joint or several, to which such holder or underwriter may become subject under the Securities Act or otherwise, insofar as such losses, claims, damages or liabilities (or
actions in respect thereof) arise out of or are based upon an untrue statement or alleged untrue statement of a material fact contained in any Exchange Offer Registration Statement or Shelf Registration Statement, as the case may be (or any
amendment or supplement thereto), under which such Registrable Securities were registered under the Securities Act, including all exhibits therein and documents incorporated by reference thereto, or any preliminary or final prospectus contained
therein or furnished by the Issuer to any such holder, Electing Holder or underwriter, or any amendment or supplement thereto, or any free writing prospectus (as defined in Rule 405) prepared by or on behalf of the Issuer or used or referred to by
the Issuer in connection with the Exchange Offers or the Shelf Registration, or arise out of or are based upon the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements
therein, in light of the circumstances under which they were made, not misleading, and will reimburse such holder, such Electing Holder and such underwriter for any reasonable and duly documented legal or other expenses incurred by them in
connection with investigating or defending any such action or claim as such expenses are incurred; provided, however, that the Issuer shall not be liable to any such person in any such case to the extent that any such loss, claim,
damage or liability arises out of or is based upon an untrue statement or alleged untrue statement or omission or alleged omission made in such registration statement, or preliminary, final or summary prospectus, or amendment or supplement thereto,
in reliance upon and in conformity with written information furnished to the Issuer by such person expressly for use therein. 

  
 17 








 (b) Indemnification by the Holders and Underwriters. The Issuer may
require, as a condition to including any Registrable Securities in any registration statement filed pursuant to Section 2(b) hereof and to entering into any underwriting agreement with respect thereto, that the Issuer shall have received an
undertaking reasonably satisfactory to it from the Electing Holder of such Registrable Securities and from each underwriter named in any such underwriting agreement, severally and not jointly, to (i) indemnify and hold harmless the Issuer and
all other holders of Registrable Securities, against any losses, claims, damages or liabilities to which the Issuer or such other holders of Registrable Securities may become subject, under the Securities Act or otherwise, insofar as such losses,
claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon an untrue statement or alleged untrue statement of a material fact contained in such registration statement, or any preliminary, final or summary
prospectus contained therein or furnished by the Issuer to any such Electing Holder or underwriter, or any amendment or supplement thereto, or arise out of or are based upon the omission or alleged omission to state therein a material fact required
to be stated therein or necessary to make the statements therein, in light of the circumstances under which they were made, not misleading, in each case to the extent, but only to the extent, that such untrue statement or alleged untrue statement or
omission or alleged omission was made in reliance upon and in conformity with written information furnished to the Issuer by such Electing Holder or underwriter expressly for use therein, and (ii) reimburse the Issuer for any reasonable and
duly documented legal or other expenses incurred by the Issuer in connection with investigating or defending any such action or claim as such expenses are incurred; provided, however, that no such Electing Holder shall be required to
undertake liability to any person under this Section 6(b) for any amounts in excess of the dollar amount of the proceeds to be received by such Electing Holder from the sale of such Electing Holder’s Registrable Securities pursuant to such
registration. 
 (c) Notices of Claims, Etc. Promptly after receipt by an indemnified party under
Section 6(a) or Section 6(b) above of written notice of the commencement of any action, such indemnified party shall, if a claim in respect thereof is to be made against an indemnifying party pursuant to the indemnification provisions
of or contemplated by this Section 6, notify such indemnifying party in writing of the commencement of such action; but the omission so to notify the indemnifying party shall not relieve it from any liability which it may have to any
indemnified party otherwise than under the indemnification provisions of or contemplated by Section 6(a) or Section (b) above. In case any such action shall be brought against any indemnified party and it shall notify an indemnifying party
of the commencement thereof, such indemnifying party shall be entitled to participate therein and, to the extent that it shall wish, jointly with any other indemnifying party similarly notified, to assume the defense thereof, with counsel reasonably
satisfactory to such indemnified party (who shall not, except with the consent of the indemnified party, be counsel to the indemnifying party), and, after notice from the indemnifying party to such indemnified party of its election so to assume the
defense thereof, such indemnifying party shall not be liable to such indemnified party for any legal expenses of other counsel or any other expenses, in each case subsequently incurred by such indemnified party, in connection with the defense
thereof other than reasonable and duly documented costs in a manner customary for the indemnified party of investigation. The indemnifying party shall not be liable for any settlement of any proceeding effected without its written consent, which
shall not be unreasonably withheld. No indemnifying party shall, without the written consent of the indemnified party, effect the settlement or compromise of, or consent to the entry of any judgment with respect to, any pending


  
 18 








 
or threatened action or claim in respect of which indemnification or contribution may be sought hereunder (whether or not the indemnified party is an actual or potential party to such action or
claim) unless such settlement, compromise or judgment (i) includes an unconditional release of the indemnified party from all liability arising out of such action or claim and (ii) does not include a statement as to or an admission of
fault, culpability or a failure to act by or on behalf of any indemnified party. 
 (d) Contribution. If for any
reason the indemnification provisions contemplated by Section 6(a) or Section 6(b) are unavailable to hold harmless an indemnified party in respect of any losses, claims, damages or liabilities (or actions in respect thereof) referred to
therein although applicable in accordance with their terms, then each indemnifying party shall contribute to the amount paid or payable by such indemnified party as a result of such losses, claims, damages or liabilities (or actions in respect
thereof) in such proportion as is appropriate to reflect the relative fault of the indemnifying party and the indemnified party in connection with the statements or omissions which resulted in such losses, claims, damages or liabilities (or actions
in respect thereof), as well as any other relevant equitable considerations. The relative fault of such indemnifying party and indemnified party shall be determined by reference to, among other things, whether the untrue or alleged untrue statement
of a material fact or omission or alleged omission to state a material fact relates to information supplied by such indemnifying party or by such indemnified party, and the parties’ relative intent, knowledge, access to information and
opportunity to correct or prevent such statement or omission. The parties hereto agree that it would not be just and equitable if contributions pursuant to this Section 6(d) were determined by pro rata allocation (even if the holders or any
underwriters or all of them were treated as one entity for such purpose) or by any other method of allocation which does not take account of the equitable considerations referred to in this Section 6(d). The amount paid or payable by an
indemnified party as a result of the losses, claims, damages or liabilities (or actions in respect thereof) referred to above shall be deemed to include any legal or other fees or expenses reasonably incurred by such indemnified party in connection
with investigating or defending any such action or claim. Notwithstanding the provisions of this Section 6(d), no holder shall be required to contribute any amount in excess of the amount by which the dollar amount of the proceeds received by
such holder from the sale of any Registrable Securities (after deducting any fees, discounts and commissions applicable thereto) exceeds the amount of any damages which such holder has otherwise been required to pay by reason of such untrue or
alleged untrue statement or omission or alleged omission, and no underwriter shall be required to contribute any amount in excess of the amount by which the total price at which the Registrable Securities underwritten by it and distributed to the
public were offered to the public exceeds the amount of any damages which 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) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. The holders’ and any underwriters’ obligations in
this Section 6(d) to contribute shall be several in proportion to the principal amount of Registrable Securities registered or underwritten, as the case may be, by them and not joint. 

(e) The obligations of the Issuer under this Section 6 shall be in addition to any liability which the Issuer may
otherwise have and shall extend, upon the same terms and conditions, to each officer, director and partner of each holder and underwriter and each person, if any, who controls any holder, agent or underwriter within the meaning of the Securities
Act, and the obligations of the holders and any agents or underwriters contemplated by this Section 6 shall be in addition to any liability which the respective holder, agent or underwriter may otherwise have


  
 19 








 
and shall extend, upon the same terms and conditions, to each officer and director of the Issuer (including any person who, with his consent, is named in any registration statement as about to
become a director of the Issuer) and to each person, if any, who controls the Issuer within the meaning of the Securities Act. 
 7.
Underwritten Offerings. 
 (a) Selection of Underwriters. If any of the Registrable Securities covered by the
Shelf Registration are to be sold pursuant to an underwritten offering, the managing underwriter or underwriters thereof shall be designated by Electing Holders holding at least a majority in aggregate principal amount of the Registrable Securities
to be included in such offering, provided, however, that such designated managing underwriter or underwriters is or are acceptable to the Issuer. 

(b) Participation by Holders. Each holder of Registrable Securities hereby agrees with each other such holder that no
such holder may participate in any underwritten offering hereunder unless such holder (i) agrees to sell such holder’s Registrable Securities on the basis provided in any underwriting arrangements approved by the persons entitled hereunder
to approve such arrangements and (ii) completes and executes all questionnaires, powers of attorney, indemnities, underwriting agreements and other documents reasonably required under the terms of such underwriting arrangements. 

8. Rule 144. 
 The
Issuer covenants to the holders of Registrable Securities that to the extent it shall be required to do so under the Exchange Act, the Issuer shall timely file the reports required to be filed by it under the Exchange Act or the Securities Act
(including the reports under Sections 13 and 15(d) of the Exchange Act referred to in subparagraph (c)(1) of Rule 144 adopted by the Commission under the Securities Act) and the rules and regulations adopted by the Commission
thereunder, and shall take such further action as any holder of Registrable Securities may reasonably request, all to the extent required from time to time to enable such holder to sell Registrable Securities without registration under the
Securities Act within the limitations of the exemption provided by Rule 144, as such Rule may be amended from time to time, or any similar or successor rule or regulation hereafter adopted by the Commission. Upon the request of any holder
of Registrable Securities in connection with that holder’s sale pursuant to Rule 144, the Issuer shall deliver to such holder a written statement as to whether it has complied with such requirements.

any amendment or waiver effected pursuant to this Section 9(g), whether or not any notice, writing or marking indicating such amendment or waiver appears on such Registrable Securities or is delivered to such holder.

 (j) Agent for Service; Submission to Jurisdiction; Waiver of Immunities. The Issuer hereby appoints the Consul
General of Mexico in New York City (currently Ms. Sandra Fuentes-Berain) and its successors as its authorized agent (the “Authorized Agent”) upon which process may be served in any action by any Purchaser, or by any persons

District of New York and any appellate court or body thereto (collectively, the “Federal Courts”) referred to below. Each of the parties hereto irrevocably submits to the jurisdiction of the Federal Courts in respect of any action arising
out of or based upon this Agreement and irrevocably waives any objection which it may now or hereafter have to the laying of venue of any such action in any such court, and each such party further waives any right to which it may be entitled on
account of present or future residence or domicile. The appointment made by the Issuer shall be irrevocable as long as any of the Securities remain outstanding, unless and until a successor agent shall have been appointed the Issuer’s
Authorized Agent and such successor agent shall have accepted such appointment. The Issuer will take any and all action, including the filing of any and all documents and instruments, that may be necessary to continue such appointment or
appointments in full force and effect as aforesaid. Service of process upon the Authorized Agent at 27 East 39th Street, New York, New York 10016, and written notice of such service mailed or delivered to the Issuer at the address set forth in
Section 9(b) above shall be deemed, in every respect, effective service of process upon the Issuer. The Issuer hereby waives irrevocably any immunity from jurisdiction to which it might otherwise be entitled (including, to the extent
applicable, sovereign immunity, immunity to pre-judgment attachment, post-judgment attachment and execution) in any such action in any federal court in The City of New York, or in any competent court in Mexico, subject to certain restrictions
pursuant to applicable law, including (i) the adoption of the Law of Petróleos Mexicanos, the Hydrocarbons Law and any other new law or regulation or (ii) any amendment to, or change in the interpretation or administration of, any
existing law or regulation, in each case, pursuant to or in connection with the Energy Reform Decree by any governmental authority in Mexico with oversight or authority over the Issuer or its subsidiaries.
