 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. $2,360,430,000 6.490% Notes due 2027 (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. $2,360,430,000, 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”). 

  
 R-2 

 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 and Pemex Logística and their respective successors and assignees, each a productive state-owned company of the Federal 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, September 23, 2019, September 27, 2019 and
October 11, 2019, 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 July 23, 2020 or from the most recent Interest Payment Date to which interest has
been paid or duly provided for, at the rate of 6.490% 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. 

  
 R-3 

 (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 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. 

  
 R-4 

 (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.

 (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. 

  
 R-5 

 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. 

(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). 

  
 R-6 

 (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. 

  
 R-7 

 (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. 

(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.

60 days’ notice by mail, in whole or in part, at any time or from time to time prior to Stated Maturity, as specified below.
