 REVERSE OF NOTE 

1. This Note is one of a duly authorized series of Securities of Petróleos Mexicanos (the “Issuer”) designated as its
U.S. $2,000,000,000 6.500% Notes due 2029 (the “Notes”), issued and to be issued in accordance with an indenture dated as of January 27, 2009, between the Issuer and Deutsche Bank Trust Company Americas, as trustee (herein called
the “Trustee,” which term includes any successor trustee under the Indenture), as supplemented by (i) the First Supplemental Indenture, dated as of June 2, 2009, among the Issuer, the Trustee and Deutsche Bank AG, London Branch
as International Paying and Authenticating Agent, (ii) the Second Supplemental Indenture, dated as of October 13, 2009, among the Issuer, the Trustee, Credit Suisse AG, as Principal Swiss Paying Agent and Authenticating Agent, and BNP
Paribas (Suisse) S.A., as Swiss Paying Agent, (iii) the Third Supplemental Indenture, dated as of April 10, 2012, among the Issuer, the Trustee and Credit Suisse AG, as Swiss Paying Agent and Authenticating Agent, (iv) the Fourth
Supplemental Indenture, dated as of June 24, 2014, between the Issuer and the Trustee, (v) the Fifth Supplemental Indenture, dated as of October 15, 2014, between the Issuer and the Trustee, (vi) the Sixth Supplemental Indenture,
dated as of December 8, 2015, among the Issuer, the Trustee, BNP Paribas (Suisse) SA, as Principal Swiss Paying Agent and Authenticating Agent, and Credit Suisse AG, as Swiss Paying Agent, (vii) the Seventh Supplemental Indenture, dated as
of June 14, 2016, among the Issuer, the Trustee, Credit Suisse AG, as Principal Swiss Paying Agent and Authentication Agent, and UBS AG, as Swiss Paying Agent, (viii) the Eighth Supplemental Indenture, dated as of February 16, 2018,
between the Issuer and the Trustee and (ix) the Ninth Supplemental Indenture, dated as of June 4, 2018, among the Issuer, the Trustee, BNP Paribas (Suisse) as Principal Swiss Paying and Authentication Agent and UBS AG as Swiss Paying Agent
(as supplemented, the “Indenture”), copies of which Indenture are on file and available for inspection at the Corporate Trust Office of the Trustee in the Borough of Manhattan, The City of New York and, so long as the Notes are listed
on the Luxembourg Stock Exchange and such Exchange shall so require, at the office of the Paying Agent in Luxembourg. Reference is hereby made to the Indenture for a statement of the respective rights, limitations of rights, duties and immunities
thereunder of the Issuer and the Holders of the Notes and of the terms upon which the Notes are, and are to be, authenticated and delivered. The Notes are limited to an aggregate initial principal amount of U.S. $2,000,000,000, subject to
increase as provided in Paragraph 10 below. Capitalized terms not otherwise defined herein or on the face of this Note shall have the meanings assigned to them in the Indenture. 

The Notes are direct, unsecured and unsubordinated Public External Indebtedness (as defined in Paragraph 8 below) of the Issuer for money
borrowed and will at all times rank pari passu with each other. The payment obligations of the Issuer under the Notes will, except as may be provided by applicable law and subject to Section 10.06 of the Indenture, at all times rank
pari passu with all other present and future unsecured and unsubordinated Public External Indebtedness for money borrowed of the Issuer. The Notes are not obligations of, or guaranteed by, the United Mexican States
(“Mexico”). 
 The Issuer’s payment obligations under the Notes and the Indenture will have the benefit of unconditional,
joint and several guaranties (the “Guaranties”) as to payment of principal, interest and any other amounts payable by the Issuer under the Notes from each of Pemex Exploración y Producción, Pemex Transformación
Industrial, Pemex Perforación y Servicios and Pemex Logística, each a productive state-owned company of the Federal 

  
 5 

 
Government (each, a “Guarantor” and, together, the “Guarantors”), pursuant to a guaranty agreement, dated July 29, 1996 (the “Guaranty Agreement”), among the
Issuer and Pemex-Exploración y Producción, Pemex-Refinación and Pemex-Gas y Petroquímica Básica, each a decentralized public entity and former subsidiary entity of
Petróleos Mexicanos, whose rights and obligations under the Guaranty Agreement were expressly assumed by the Guarantors effective as of November 1, 2015. The Issuer has designated each of the Indenture and the Notes as obligations of the
Issuer entitled to the benefits of the Guaranty Agreement, pursuant to certificates of designation, each dated January 27, 2009, January 14, 2010, December 22, 2010, January 22, 2013, January 31, 2014, January 22, 2015,
January 25, 2016, February 9, 2017, April 17, 2018 and October 23, 2018, respectively (the “Certificates of Designation”). 

The Notes are denominated in U.S. dollars. Payments on the Notes will be made in U.S. dollars. The Notes are issuable only in fully registered
form, without interest coupons. The Notes are issuable in authorized denominations of U.S. $10,000 and integral multiples of U.S. $1,000 in excess thereof. 

2. (a) The Notes will bear interest from October 23, 2018 or from the most recent Interest Payment Date to which interest has been paid or
duly provided for, at the rate of 6.500% per annum, until the principal hereof has been paid or duly made available for payment. The interest on this Note shall be payable in arrears on each Interest Payment Date specified on the face hereof, and
shall be computed on the basis of a 360-day year consisting of twelve 30-day months. Any payment on this Note due on any day which is not a Business Day in The City of
New York or the place of payment need not be made on such day, but may be made on the next succeeding Business Day with the same force and effect as if made on the due date, and no interest shall accrue for the period from and after such due date.
“Business Day,” as used herein with respect to any particular location, means each Monday, Tuesday, Wednesday, Thursday and Friday which is not a day on which banking institutions in such location are authorized or obligated by law to
close in such location. 
 (b) The interest so payable, and punctually paid or duly provided for, on any Interest Payment Date will be paid
to the person in whose name this Note (or one or more predecessor Notes) is registered at the close of business on the 15th day (whether or not a Business Day) (the “Regular Record Date”) next preceding such Interest Payment Date;
provided that interest payable at Stated Maturity will be payable to the person to whom principal shall be payable; and provided, further, that if this Note is a Global Security, any payment of interest on this Note shall be
made to the applicable Depositary or its nominee, as the registered owner hereof. Any such interest not so punctually paid or duly provided for will forthwith cease to be payable to the Holder on such Regular Record Date and may either be paid to
the person in whose name this Note (or one or more predecessor Notes) is registered at the close of business on a special record date for the payment of such defaulted interest to be fixed by the Trustee, notice whereof shall be given to Holders of
Notes not less than 10 days prior to such special record date, or be paid at any time in any other lawful manner not inconsistent with the requirements of any securities exchange on which the Notes may be listed, and upon such notice as may be
required by such exchange. 
 (c) Payment of principal (and premium, if any) and any interest due with respect to the Notes at Stated
Maturity will be made in immediately available funds upon surrender of such Notes at the corporate trust office of the Trustee in the Borough of Manhattan, The City of 

  
 6 

 
New York, or at the specified office of any other Paying Agent, provided that the Note is presented to the Paying Agent in time for the Paying Agent to make such payments in such funds in
accordance with its normal procedures. Payments of principal (and premium, if any) and any interest in respect of this Note to be made other than at Stated Maturity or upon redemption will be made by check mailed on or before the due date for such
payments to the address of the persons entitled thereto as they appear in the Security Register; provided that (i) the applicable Depositary, as Holder of the Global Securities, shall be entitled to receive payments of interest by wire
transfer of immediately available funds and (ii) a Holder of U.S. $10,000,000 in aggregate principal or face amount of Notes having the same Interest Payment Date shall be entitled to receive payments of interest by wire transfer to an
account maintained by such Holder at a bank located in the United States as may have been appropriately designated by such person to the Paying Agent in writing no later than the relevant Regular Record Date. Unless such designation is revoked, any
such designation made by such Holder with respect to such Note shall remain in effect with respect to any further payments with respect to such Note payable to such Holder. 

3. (a) The Issuer shall maintain in the Borough of Manhattan, The City of New York, an office or agency where Notes may be surrendered for
registration of transfer or exchange. The Issuer has initially appointed the Corporate Trust Office of the Trustee as its agent in the Borough of Manhattan, The City of New York, for such purpose and has agreed to cause to be kept at such office a
register in which, subject to such reasonable regulations as it may prescribe, the Issuer will provide for the registration of Notes and registration of transfers of Notes. The Issuer reserves the right to vary or terminate the appointment of the
Trustee as security registrar or of any Transfer Agent or to appoint additional or other registrars or Transfer Agents or to approve any change in the office through which any security registrar or any Transfer Agent acts, provided that there
will at all times be a security registrar in the Borough of Manhattan, The City of New York and, so long as the Notes are listed on the Luxembourg Stock Exchange and such Exchange shall so require, a Transfer Agent in Luxembourg. 

(b) The transfer or exchange of a Note is registrable on the aforementioned register upon surrender of such Note at the Corporate Trust Office
of the Trustee or any Transfer Agent duly endorsed by, or accompanied by a written instrument of transfer in form satisfactory to the Issuer and the Trustee duly executed by the Holder thereof or his attorney duly authorized in writing. Upon such
surrender of a Note for registration of transfer, the Issuer shall execute one or more new Notes of any authorized denominations and of a like form, tenor and terms and a like aggregate principal amount, and the Trustee shall authenticate and
deliver in the name of the designated transferee or transferees, such new Notes, dated the date of authentication thereof. At the option of the Holder upon request confirmed in writing, Notes may be exchanged for Notes of any authorized
denominations and of a like form, tenor and terms and a like aggregate principal amount upon surrender of the Notes to be exchanged at the office of any Transfer Agent or at the corporate trust office of the Trustee. Whenever any Notes are so
surrendered for exchange, the Issuer shall execute the Notes which the Holder making the exchange is entitled to receive, and the Trustee shall authenticate and deliver such Notes. 

(c) Any registration of transfer or exchange will be effected upon the Transfer Agent or the Trustee, as the case may be, being satisfied with
the documents of title and identity of the person making the request and subject to such reasonable regulations as the Issuer may from time to time agree with any Transfer Agents and the Trustee. 

  
 7 

 (d) In the event of a redemption of Notes in part (if permitted by the provisions hereof),
the Issuer shall not be required (i) to register the transfer of or exchange any Note during a period beginning at the opening of business 15 days before, and continuing until, the date on which notice is given identifying the Notes to be
redeemed, or (ii) to register the transfer of or exchange any Note, or portion thereof, called for redemption. 
 (e) All Notes issued
upon any registration of transfer or exchange of Notes shall be the valid obligations of the Issuer, evidencing the same debt, and entitled to the same benefits, as the Notes surrendered upon such registration of transfer or exchange. No service
charge shall be made for any registration of transfer or exchange, but the Issuer may require payment of a sum sufficient to cover any stamp tax or other governmental charge payable in connection therewith, other than an exchange in connection with
a partial redemption of a Note not involving any registration of a transfer. 
 Prior to due presentment of this Note for registration of
transfer, the Issuer, each Guarantor, the Trustee and any agent of the Issuer, any Guarantor or 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 be overdue, and
neither the Issuer, any Guarantor, the Trustee nor any such agent shall be affected by any notice to the contrary. 
 4. The Issuer shall pay
to the Trustee at its principal office in the Borough of Manhattan, The City of New York, on or prior to 11:00 a.m., New York City time, on each Interest Payment Date, any Redemption Date and at the Stated Maturity of the Notes, in such amounts
sufficient (with any amounts then held by the Trustee and available for the purpose) to pay the interest on, the Redemption Price of and accrued interest (if the Redemption Date is not an Interest Payment Date) on, and the principal of, the Notes
due and payable on such Interest Payment Date, Redemption Date or Stated Maturity, as the case may be. The Trustee shall apply the amounts so paid to it to the payment of such interest, Redemption Price and principal in accordance with the terms of
the Notes. Any monies paid by the Issuer to the Trustee for the payment of the principal, premium (if any) or interest on any Notes and remaining unclaimed at the end of two years after such principal (or premium, if any) or interest shall have
become due and payable (whether at the Stated Maturity, upon call for redemption or otherwise) shall then be repaid to the Issuer upon its written request, and upon such repayment all liability of the Trustee with respect thereto shall cease,
without, however, limiting in any way any obligation the Issuer may have to pay the principal of (and premium, if any) and interest on each Note as the same shall become due. Notwithstanding the foregoing, the right of the Holders to receive any
payment of principal of (whether on the Stated Maturity, upon call for redemption or otherwise) or interest on the Notes will become void at the end of five years after the due date for such payment. 

5. (a) The Issuer will pay all stamp and other duties, if any, which may be imposed by the United States or any political subdivision thereof
or taxing authority of or in the foregoing with respect to the Indenture or the issuance of this Note. Except as otherwise provided herein, the Issuer shall not be required to make any payment with respect to any tax, assessment or other
governmental charge imposed by any government or any political subdivision or taxing authority thereof or therein. 

  
 8 

 (b) The Issuer, or, in the case of a payment by a Guarantor, such Guarantor, will pay to the
Holder of this Note such additional amounts (“Additional Amounts”) as may be necessary in order that every net payment made by the Issuer or a Guarantor on this Note after deduction or withholding for or on account of any present or future
tax, assessment or other governmental charge imposed upon or as a result of such payment by Mexico or any political subdivision or taxing authority thereof or therein (“Mexican Withholding Taxes”), will not be less than the amount provided
for in this Note and in the Indenture to be then due and payable on this Note. The foregoing obligation to pay Additional Amounts, however, will not apply to (i) any Mexican Withholding Taxes that would not have been imposed or levied on the
Holder of this Note but for the existence of any present or former connection between such Holder and Mexico or any political subdivision or territory or possession thereof or area subject to its jurisdiction, including, without limitation, such
Holder (A) being or having been a citizen or resident thereof, (B) maintaining or having maintained an office, permanent establishment or branch therein, or (C) being or having been present or engaged in trade or business therein,
except for a connection solely arising from the mere ownership of, or receipt of payment under, this Note; (ii) except as otherwise provided, any estate, inheritance, gift, sales, transfer or personal property or similar tax, assessment or
other governmental charge; (iii) any Mexican Withholding Taxes that are imposed or levied by reason of the failure by such Holder to comply with any certification, identification, information, documentation, declaration or other reporting
requirement that is required or imposed by a statute, treaty, regulation, general rule or administrative practice as a precondition to exemption from, or reduction in the rate of, the imposition, withholding or deduction of any Mexican Withholding
Taxes; provided that at least 60 days prior to (A) the first payment date with respect to which the Issuer or a Guarantor shall apply this clause (iii) and, (B) in the event of a change in such certification,
identification, information, documentation, declaration or other reporting requirement, the first payment date subsequent to such change, the Issuer or a Guarantor, as the case may be, shall have notified the Trustee in writing that the Holders of
Notes will be required to provide such certification, identification, information or documentation, declaration or other reporting; (iv) any Mexican Withholding Taxes imposed at a rate in excess of 4.9% in the event that such Holder has failed
to provide on a timely basis, at the reasonable request of the Issuer, information or documentation (not described in clause (iii) above) concerning such Holder’s eligibility, if any, for benefits under an income tax treaty that is in
effect to which Mexico is a party that is necessary to determine the appropriate rate of deduction or withholding of Mexican Withholding Taxes under any such treaty; (v) any Mexican Withholding Taxes that would not have been so imposed but for
the presentation by such Holder of this Note for payment on a date 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, whichever occurs later; (vi) any payment
on this Note to any Holder who is a fiduciary or partnership or other than the sole beneficial owner of any such payment, to the extent that a beneficiary or settlor with respect to such fiduciary, a member of such a partnership or the beneficial
owner of such payment would not have been entitled to the Additional Amounts had such beneficiary, settlor, member or beneficial owner been the Holder of this Note, or (vii) a Note presented for payment by or on behalf of a Holder who would
have been able to avoid such withholding or deduction by presenting the relevant Note to another Paying Agent in a member state of the European Union. All references in this Note or in the Indenture to principal, premium, if any, interest and
Redemption Price or any other amount payable under or with respect to the Notes shall, unless the context otherwise requires, be deemed to mean and include all Additional Amounts, if any, payable in respect thereof as set forth in this paragraph
(b). 

  
 9 

 (c) Notwithstanding the foregoing, the limitations on the Issuer’s and the
Guarantors’ obligation to pay Additional Amounts set forth in clauses (iii) and (iv) of paragraph (b) above shall not apply if the provision of the certification, identification, information, documentation, declaration or other
evidence described in such clauses (iii) and (iv) would be materially more onerous, in form, in procedure or in the substance of information disclosed, to a Holder or beneficial owner of this Note (taking into account any relevant differences
between United States and Mexican law, regulation or administrative practice) than comparable information or other applicable reporting requirements imposed or provided for under United States federal income tax law (including the United
States-Mexico Income Tax Treaty), regulation (including proposed regulations) and administrative practice. In addition, the limitations on the Issuer’s and the Guarantors’ obligation to pay Additional Amounts set forth in clauses
(iii) and (iv) of paragraph (b) above shall not apply if Article 166, Section II, paragraph a) of the Mexican Income Tax Law (or a substantially similar successor of such provision) is in effect, unless (A) the
provision of the certification, identification, information, documentation, declaration or other evidence described in clauses (iii) and (iv) is expressly required by statute, regulation, general rules or administrative practice in order to
apply Article 166, Section II, paragraph a) of the Mexican Income Tax Law (or a substantially similar successor of such provision), the Issuer or the applicable Guarantor cannot obtain such certification, identification, information,
documentation, declaration or evidence, or satisfy any other reporting requirements, on its own through reasonable diligence and the Issuer or the applicable Guarantor otherwise would meet the requirements for application of Article 166,
Section II, paragraph a) of the Mexican Income Tax Law (or such successor provision) or (B) in the case of a Holder or beneficial owner of a Note that is a pension fund or other tax-exempt organization,
such Holder or beneficial owner would be subject to Mexican Withholding Taxes at a rate less than that provided by Article 166, Section II, paragraph a) of the Mexican Income Tax Law (or such successor provision) if the information,
documentation or other evidence required under clause (iv) of paragraph (b) above were provided. In addition, clauses (iii) and (iv) of paragraph (b) above shall not be construed to require that a
non-Mexican pension or retirement fund, a non-Mexican tax-exempt organization or a
non-Mexican financial institution or any other Holder or beneficial owner of this Note register with the Ministry of Finance and Public Credit of Mexico for the purpose of establishing eligibility for an
exemption from or reduction of Mexican Withholding Taxes. 
 (d) The Issuer or a Guarantor, as the case may be, will, upon written request,
provide the Trustee, the Holders and the Paying Agents with a duly certified or authenticated copy of an original receipt of the payment of Mexican Withholding Taxes which such Issuer or Guarantor has withheld or deducted in respect of any payments
made under or with respect to the Notes or the Guaranties, as the case may be. 
 (e) Any reference herein or in the Indenture to principal,
interest, Redemption Price or any other amount payable under or with respect to the Notes will be deemed also to refer to any Additional Amounts which may be payable under the undertakings referred to herein. 

  
 10 

 (f) In the event that Additional Amounts actually paid with respect to this Note are based
on rates of deduction or withholding of Mexican Withholding Taxes in excess of the appropriate rate applicable to the Holder or beneficial owner of this Note, and, as a result thereof, such Holder or beneficial owner is entitled to make a claim for
a refund or credit of such excess, then such Holder or beneficial holder shall, by accepting this Note, 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 Issuer or
the applicable Guarantor, as the case may be. However, by making such assignment, the Holder or beneficial owner makes no representation or warranty that the Issuer or the applicable Guarantor, as the case may be, will be entitled to receive such
claim for a refund or credit and such Holder or beneficial owner incurs no other obligation with respect thereto. 
 6. (a) This Note may not
be redeemed prior to the Stated Maturity, except as specified in paragraphs (b) and (c) below. 
 (b) The Notes may be redeemed at the
option of the Issuer in whole, but not in part, at any time, together, if applicable, with interest accrued to but excluding the date fixed for redemption, at par, on giving not less than 30 nor more than 60 days’ notice to the Holders of the
Notes (which notice shall be irrevocable), if (i) the Issuer or any Guarantor certifies to the Trustee immediately prior to the giving of such notice that it has or will become obligated to pay Additional Amounts in excess of the Additional
Amounts that it would be obligated to pay if payments (including payments of interest) on the Notes (or payments under the Guaranties with respect to interest on the Notes) were subject to Mexican Withholding Tax at a rate of 10%, as a result of any
change in, amendment to, or lapse of, the laws, rules or regulations of Mexico or any political subdivision or any taxing authority thereof or therein affecting taxation, or any change in, or amendment to, an official interpretation or application
of such laws, rules or regulations, which change or amendment becomes effective on or after the date of issuance of the Notes and (ii) prior to the publication of any notice of redemption, the Issuer or any Guarantor shall deliver to the
Trustee an Officer’s Certificate stating that the obligation referred to in (i) above cannot be avoided by the Issuer or such Guarantor, as the case may be, taking reasonable measures available to it, and the Trustee shall be entitled to
accept such certificate as sufficient evidence of the satisfaction of the condition precedent set out in (i) above in which event it shall be conclusive and binding on the Holders of the Notes; provided that no such notice of redemption
shall be given earlier than 90 days prior to the earliest date on which the Issuer or such Guarantor, as the case may be, would be obligated but for such redemption to pay such Additional Amounts were a payment in respect of the Notes then due and,
at the time such notice is given, such obligation to pay such Additional Amounts remains in effect. 
 (c) The Notes are subject to
redemption upon not less than 30 nor more than 60 days’ notice by mail, in whole or in part, at any time or from time to time prior to Stated Maturity, at a Redemption Price equal to the sum of (A) 100% of the principal amount of such
Notes and (B) the Make-Whole Amount (as defined below), plus accrued interest on the principal amount of the Notes to the date of redemption. “Make-Whole Amount” means the excess of (i) the sum of the present values of each
remaining scheduled payment of principal and interest on the applicable Notes (exclusive of interest accrued to the Redemption Date), discounted to the Redemption Date on a semi-annual basis (assuming a
360-day year consisting of twelve 30-day months) at the Treasury Rate (as defined below) plus 50 basis points over 

  
 11 

 
(ii) the principal amount of such Notes. “Treasury Rate” means, with respect to any Redemption Date, the rate per annum equal to the semi-annual equivalent yield to maturity or

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

 (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, 2020 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 than the later of March 1, 2020 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, 2019, (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, 2020, (iii) the Exchange Offers are not consummated on or before April 5, 2020, (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. 
 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. 

  
 7 

 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. 

(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. 
 3. Registration Procedures. 

If the Issuer files a registration statement pursuant to Section 2(a) or Section 2(b), the following provisions shall apply: 

(a) At or before the Effective Time of the Exchange Offers or the Shelf Registration, as the case may be, the Issuer shall
cause the Indenture to be qualified under the Trust Indenture Act.

jurisdiction wherein it would not otherwise be required to qualify but for the requirements of this Section 3(c)(vi), (2) consent to general service of process in any such jurisdiction or (3) make any changes to its certificate of

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 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

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 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

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. 

  
 18 

 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. 

(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 

  
 19 

 
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 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 

  
 20 

 
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 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. 

  
 21 

 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. 
 9. Miscellaneous. 

(a) No Inconsistent Agreements. The Issuer represents, warrants, covenants and agrees that it has not granted, and shall
not grant, registration rights with respect to Registrable Securities or any other securities which would be inconsistent with the rights granted to the holders of the Registrable Securities in this Agreement. 

(b) Notices. All notices, requests, claims, demands, waivers and other communications hereunder shall be in writing and
shall be deemed to have been duly given when delivered by hand, if delivered personally or by courier, as follows: If to the Issuer, to it at Petróleos Mexicanos, Avenida Marina Nacional No. 329, Colonia Verónica Anzures, Ciudad
de México, 11300, México, and if to a holder, to the address of such holder set forth in the security register or other records of the Issuer, or to such other address as the Issuer or any such holder may have furnished to the other in
writing in accordance herewith, except that notices of change of address shall be effective only upon receipt. 

  
 22 

 (c) Parties in Interest. All the terms and provisions of this
Agreement shall be binding upon, shall inure to the benefit of and shall be enforceable by the parties hereto and the holders from time to time of the Registrable Securities and the respective successors and assigns of the parties hereto and such
holders. In the event that any transferee of any holder of Registrable Securities shall acquire Registrable Securities, in any manner, whether by gift, bequest, purchase, operation of law or otherwise, such transferee shall, without any further
writing or action of any kind, be deemed a beneficiary hereof for all purposes, and such Registrable Securities shall be held subject to all of the terms of this Agreement; and by taking and holding such Registrable Securities such transferee shall
be entitled to receive the benefits of, and be conclusively deemed to have agreed to be bound by, all of the applicable terms and provisions of this Agreement. If the Issuer shall so request, any such successor, assign or transferee shall agree in
writing to acquire and hold the Registrable Securities subject to all of the applicable terms hereof. 
 (d) Survival.
The respective indemnities, agreements, representations, warranties and each other provision set forth in this Agreement or made pursuant hereto shall remain in full force and effect regardless of any investigation (or statement as to the results
thereof) made by or on behalf of any holder of Registrable Securities, the Issuer, any director, officer or partner of such holder or the Issuer, any agent or underwriter or any director, officer or partner thereof, or any controlling person of any
of the foregoing, and shall survive delivery of and payment for the Registrable Securities pursuant to the Terms Agreement and the transfer and registration of Registrable Securities by such holder and the consummation of an Exchange Offer. 

(e) Governing Law. This Agreement, and any claim, controversy or dispute relating to or arising out of this Agreement,
shall be governed by and construed in accordance with the laws of the State of New York except that the authorization and execution of this Agreement by the Issuer shall be governed by the laws of the United Mexican States. 

(f) Headings. The descriptive headings of the several Sections and paragraphs of this Agreement are inserted for
convenience only, do not constitute a part of this Agreement and shall not affect in any way the meaning or interpretation of this Agreement. 

(g) Entire Agreement; Amendments. This Agreement and the other writings referred to herein (including the Indenture and
the form of Securities) or delivered pursuant hereto which form a part hereof contain the entire understanding of the parties with respect to its subject matter. This Agreement supersedes all prior agreements and understandings between the parties
with respect to its subject matter. This Agreement may be amended and the observance of any term of this Agreement may be waived (either generally or in a particular instance and either retroactively or prospectively) only by a written instrument
duly executed by the Issuer and the holders of at least a majority in aggregate principal amount of the Registrable Securities at the time outstanding. Each holder of any Registrable Securities at the time or thereafter outstanding shall be bound by
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. 

  
 23 

 (h) Counterparts. This Agreement may be executed by the parties in
counterparts, each of which shall be deemed to be an original, but all such respective counterparts shall together constitute one and the same instrument. 

(i) Commercial Activity. The Issuer and each of the Guarantors are subject to civil and commercial law with respect to
their obligations, as applicable, under the Agreements and the Securities. Neither the Issuer nor any of the Guarantors is entitled to any immunity, whether on grounds of sovereign immunity or otherwise, from any legal proceedings (whether through
service or notice, attachment prior to judgment, attachment in aid of execution, execution or otherwise) to enforce or collect upon this Agreement, the Indenture, the Guaranty Agreement, the Securities, or any other liability or obligation of the
Issuer and/or each of the Guarantors related to or arising from the transactions contemplated thereby in respect of itself or its property. 

(j) Agent for Service; Submission to Jurisdiction; Waiver of Immunities. The Issuer hereby appoints the Consul General
of Mexico in New York City (currently Mr Diego Gómez Pickering) 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 controlling such
Purchaser, arising out of or based upon this Agreement which each of the parties hereto hereby agrees that, in respect of any actions brought against it as a defendant may be instituted in the U.S. District Court for the Southern 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.

three (3) counterparts hereof, and upon the acceptance hereof by you, this letter and such acceptance hereof shall constitute a binding agreement among the Purchasers and the Issuer.

Notice of Registration Statement 

and 
 Selling Securityholder
Questionnaire 
 (Date) 
 Reference is
hereby made to the Exchange and Registration Rights Agreement dated October 23, 2018 (the “Exchange and Registration Rights Agreement”) among Petróleos Mexicanos (the “Issuer”) and the Purchasers named therein.
Pursuant to the Exchange and Registration Rights Agreement, the Issuer intends to file with the United States Securities and Exchange Commission (the “Commission”) a registration statement on Form [    ] (the
“Shelf Registration Statement”) for the registration and resale under Rule 415 of the Securities Act of 1933, as amended (the “Securities Act”), of the Issuer’s 6.500% Notes due 2029 (CUSIP Nos.: 71654QCM2 and
P78625DV2)) (the “Securities”). A copy of the Registration Rights Agreement is attached hereto. All capitalized terms not otherwise defined herein shall have the meanings ascribed thereto in the Exchange and Registration Rights Agreement.

 Each beneficial owner of Registrable Securities is entitled to have the Registrable Securities beneficially owned by it included in the Shelf
Registration Statement. In order to have Registrable Securities included in the Shelf Registration Statement, this Notice of Registration Statement and Selling Securityholder Questionnaire (“Notice and Questionnaire”) must be completed,

Questionnaire by such date (i) will not be named as selling securityholders in the Shelf Registration Statement and (ii) may not use the prospectus forming a part thereof for resales of Registrable Securities. 

Certain legal consequences arise from being named as a selling securityholder in the Shelf Registration Statement and related prospectus. Accordingly, holders
and beneficial owners of Registrable Securities are advised to consult their own securities law counsel regarding the consequences of being named or not being named as a selling securityholder in the Shelf Registration Statement and related
prospectus. 

 ELECTION 

The undersigned holder (the “Selling Securityholder”) of Registrable Securities hereby elects to include in the Shelf Registration Statement the
Registrable Securities beneficially owned by it and listed below in Item (3). The undersigned, by signing and returning this Notice and Questionnaire, agrees to be bound with respect to such Registrable Securities by the terms and conditions of
this Notice and Questionnaire and the Exchange and Registration Rights Agreement. Such holder agrees 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
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 holder 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 holder shall be required to undertake liability to any person hereunder for any amounts in excess of the dollar amount of the
proceeds to be received by such holder from the sale of such holder’s Registrable Securities pursuant to such registration. 
 Upon any sale of
Registrable Securities pursuant to the Shelf Registration Statement, the Selling Securityholder will be required to deliver to the Issuer and the Trustee the Notice of Transfer set forth in Appendix A to the Prospectus and as Exhibit B to
