 REVERSE OF BOND 
  

1. This Bond is one of a duly authorized series of Securities of Pemex Project Funding Master Trust (the “Issuer”) designated as its 8.625%
Guaranteed Bonds due 2023 (the “Bonds”), issued and to be issued in accordance with an indenture, dated as of December 30, 2004 (herein called the “Indenture”), among the Issuer, Petróleos Mexicanos, as Guarantor (the
“Guarantor”), and Deutsche Bank Trust Company Americas, as Trustee (herein called the “Trustee,” which term includes any successor trustee under 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 Bonds 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 Bonds and of the terms upon which the Bonds are, and are to be,
authenticated and delivered. The Bonds represented hereby will be consolidated to form a single series with, and be fully fungible with, the U.S. $[    ] principal amount of 8.625% Guaranteed Bonds due 2023 issued by the Issuer
on [    ], 2005. The Bonds are initially limited to an aggregate initial principal amount of U.S. $250,000,000 subject to increase as provided in Paragraph 10 below. Capitalized terms not otherwise defined herein or on the face
of this Bond shall have the meanings assigned to them in the Indenture. 
  
 The Bonds are direct, unsecured and unsubordinated Public External Indebtedness (as defined in Paragraph 8 below) of the Issuer for money borrowed and will rank pari passu with each other and with all other present and future
unsecured and unsubordinated Public External Indebtedness for money borrowed of the Issuer. The Bonds are not obligations of, or guaranteed by, the United Mexican States (“Mexico”). 
  
 Each of the Bonds will have the benefit of the unconditional guaranty
endorsed hereon (the “Guaranty”) as to punctual payment when due of all amounts of principal of and interest (including Additional Amounts) on the Bonds, and any other amounts payable by the Issuer under the Bonds or the Indenture. The
Guarantor’s payment obligations under the Guaranty and the Indenture will have the benefit of an unconditional guaranty as to payment of principal and interest (including Additional Amounts) jointly and severally from each of
Pemex-Exploración y Producción, Pemex-Refinación and Pemex-Gas y Petroquímica Básica (each, a “Subsidiary Guarantor” and together, the “Subsidiary Guarantors”), pursuant to a Guaranty Agreement,
dated July 29, 1996 (the “Subsidiary Guaranty”), among the Guarantor and the Subsidiary Guarantors. The Guarantor has designated its Guaranty of each of the Bonds and the Indenture as obligations of the Guarantor entitled to the benefits
of the Subsidiary Guaranty, pursuant to certificates of designation, each dated [    ], 2005 (the “Certificates of Designation”). 
  

The Bonds are denominated in U.S. dollars. The Bonds are issuable only in fully registered form, without interest coupons. The Bonds are issuable in
authorized denominations of U.S. $250,000 and integral multiples of U.S. $10,000 in excess thereof. 
  
 2. (a) The Bonds will bear interest from the date specified on the face hereof or from the most recent Interest Payment Date to which interest has been
paid or duly provided for, at the interest rate per annum specified on the face hereof, until the principal hereof has been 

  

 R-1 








 
paid or duly made available for payment. The interest on this Bond 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 Bond 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 Bond (or one or more predecessor Bonds) 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 on the Maturity Date will be payable to the
person to whom principal shall be payable; and provided, further, that if this Bond is a Global Security, any payment of interest on this Bond 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 Bond (or one or more predecessor Bonds) 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 Bonds 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 Bonds may be listed, and upon such notice as may be required by such exchange. 
  
 (c) Payment of principal and any interest due with respect to the Bonds on
the Maturity Date will be made in immediately available funds upon surrender of such Bonds 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 Bond 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 any interest in respect of this Bond to be made other
than on the Maturity Date 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 Bonds 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 Bond shall remain in effect with respect to any further payments with respect to such Bond
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 Bonds may be surrendered for registration of transfer or exchange. The Issuer has initially appointed the corporate trust office of the Trustee as its agent 

  

 R-2 








 
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 Bonds and registration of transfers of Bonds. 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 Bonds 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 Bond is registrable on the aforementioned register upon surrender of such Bond 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 Bond for registration of transfer, the Issuer shall execute one or more new Bonds of any authorized denominations and of a like form, tenor and terms and a like aggregate principal amount, the Guarantor shall
execute the Guaranty endorsed thereon, and the Trustee shall authenticate and deliver in the name of the designated transferee or transferees, such new Bonds, dated the date of authentication thereof. At the option of the Holder upon request
confirmed in writing, Bonds may be exchanged for Bonds of any authorized denominations and of a like form, tenor and terms and a like aggregate principal amount upon surrender of the Bonds to be exchanged at the office of any Transfer Agent or at
the corporate trust office of the Trustee. Whenever any Bonds are so surrendered for exchange, the Issuer and shall execute the Bonds which the Holder making the exchange is entitled to receive, the Guarantor shall execute the Guaranty endorsed
thereon, and the Trustee shall authenticate and deliver such Bonds. 
  
 (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) All Bonds issued upon any registration of transfer or exchange of Bonds shall be the valid obligations of the Issuer, evidencing the same debt, and
entitled to the same benefits, as the Bonds 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 Bond not involving any registration of a transfer. 
  
 Prior to due presentment of this Bond for registration of transfer, the
Issuer, the Guarantor, each Subsidiary Guarantor, the Trustee and any agent of the Issuer, the Guarantor, any Subsidiary Guarantor or the Trustee may treat the person in whose name this Bond is registered as the owner hereof for all purposes,
whether or not this Bond shall be overdue, and neither the Issuer, the Guarantor, any Subsidiary Guarantor, the Trustee nor any such agent shall be affected by any notice to the contrary. 
  

 R-3 








 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 Maturity Date of the Bonds, 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 Bonds due and payable on such Interest Payment Date, redemption date or Maturity Date, 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 Bonds. Any monies paid by the Issuer to the Trustee for the payment of the principal
of or interest on any Bonds and remaining unclaimed at the end of two years after such principal or interest shall have become due and payable (whether on the Maturity Date, 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 interest on each Bond as the same
shall become due. Notwithstanding the foregoing, the right of the Holders to receive any payment of principal of (whether on the Maturity Date, upon call for redemption or otherwise) or interest on the Bonds 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 Bond. 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 the Guarantor or a Subsidiary
Guarantor, such Guarantor or Subsidiary Guarantor, will pay to the Holder of this Bond such additional amounts (“Additional Amounts”) as may be necessary in order that every net payment made by the Issuer, the Guarantor or a Subsidiary
Guarantor on this Bond 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 then due and payable on this Bond. 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 Bond 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 Bond; (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 

  

 R-4 








 
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, the Guarantor or a Subsidiary 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, the Guarantor or a Subsidiary Guarantor, as the case may be, shall have notified the Trustee in writing that the Holders of Bonds 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 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 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 Bond 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 Bond 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 Bond; or (vii) any withholding tax or deduction imposed on a payment to an individual and required to be made pursuant to European Council Directive 2003/48/EC or any
other European Union Directive implementing the conclusions of the ECOFIN Council meeting of November 26-27, 2000 on the taxation of savings income, or any law implementing or complying with, or introduced in order to conform to, such a directive or
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 Bond to another Paying Agent in a Member State of the European Union. All references in this Bond or in the
Indenture to principal of and interest on the Bonds 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). 
  
 (c) Notwithstanding the foregoing, the limitations on the Issuer’s, the
Guarantor’s and the Subsidiary Guarantors’ obligation to pay Additional Amounts set forth in clauses (iii) and (iv) 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 Bond (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, the Guarantor’s and the Subsidiary Guarantors’ obligation to pay Additional
Amounts set forth in clauses (iii) and (iv) above shall not apply if Article 195, 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 

  

 R-5 








 
required by statute, regulation, general rules or administrative practice in order to apply Article 195, Section II, paragraph a) (or a substantially similar
successor of such provision), the Issuer, the Guarantor or the applicable Subsidiary 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, the Guarantor or the applicable Subsidiary Guarantor otherwise would meet the requirements for application of Article 195, Section II, paragraph a) (or such successor of such provision) or (B) in the
case of a Holder or beneficial owner of a Bond 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 195, Section II,
paragraph a) if the information, documentation or other evidence required under clause (iv) above were provided. In addition, clauses (iii) and (iv) 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 Bond 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, the
Guarantor or a Subsidiary 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, Guarantor or Subsidiary Guarantor has withheld or deducted in respect of any payments made under or with respect to the Bonds, the Guaranty or the Subsidiary Guaranty, as the case may be. 
  
 (e) In the event that Additional Amounts actually paid with respect to this
Bond are based on rates of deduction or withholding of Mexican Withholding Taxes in excess of the appropriate rate applicable to the Holder of this Bond, and, as a result thereof, such Holder is entitled to make a claim for a refund or credit of
such excess, then such Holder shall, by accepting this Bond, 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, the Guarantor or the applicable Subsidiary
Guarantor, as the case may be. However, by making such assignment, the Holder makes no representation or warranty that the Issuer, the Guarantor or the applicable Subsidiary Guarantor, as the case may be, will be entitled to receive such claim for a
refund or credit and incurs no other obligation with respect thereto. 
  
 6. (a) The Bonds may be redeemed at the option of the Issuer in whole, but not in part, at any time, at par, together with, if applicable, interest accrued to but excluding the date fixed for redemption, on giving not less than 30 nor more
than 60 days’ notice to the Holders of the Bonds (which notice shall be irrevocable), if (i) the Issuer or the 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 Bonds (or payments under the Guaranties with respect to interest on the Bonds) 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 

  

 R-6 








 
the Bonds and (ii) prior to the publication of any notice of redemption, the Issuer or the 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 the 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 Bonds; provided that no such notice of redemption shall be given earlier than 90
days prior to the earliest date on which the Issuer or the 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 Bonds then due and, at the time such notice is
given, such obligation to pay such Additional Amounts remains in effect. 
  
 (b) The Issuer, the Guarantor or any Subsidiary Guarantor may at any time purchase Bonds at any price in the open market or otherwise. Bonds so purchased by the Issuer, the Guarantor or any Subsidiary Guarantor may be
held, resold (subject to compliance with applicable securities and tax laws) or surrendered to the Trustee for cancellation. 
  
 7. The Bonds are not redeemable at the option of the Issuer, except as provided in Paragraph 6, and are not repayable at the option of the Holder, except
as provided in Paragraph 8 in the event of acceleration. 
  
 8. If
any of the following events (each, an “Event of Default”) occurs and is continuing, the Trustee, if so requested in writing by Holders of at least 20% in principal amount of the Bonds then outstanding, shall give notice to the Issuer and
the Guarantor that the Bonds are, and they shall immediately become, due and payable at their principal amount together with accrued interest: 
  
 (a) Non-Payment: default is made in payment of principal (or any part thereof) of or any interest on, any of the Bonds when
due and such failure continues, in the case of non-payment of principal for seven days, and of interest for fourteen days after the due date; or 
  
 (b) Breach of Other Obligations: the Issuer or the Guarantor defaults in performance or observance of or compliance with any
of its other obligations set out in the Bonds or the Guaranties or (insofar as it concerns the Bonds or the Guaranties) the Indenture which default is incapable of remedy or, if capable of remedy, is not remedied within 30 days after written notice
of such default shall have been given to the Issuer, the Guarantor and the Subsidiary Guarantors by the Trustee; or 
  
 (c) Cross-Default: default by the Issuer, the Guarantor or any of the Guarantor’s Material Subsidiaries (as defined
below) or the Subsidiary Guarantors or any of them or any of their respective Material Subsidiaries in the payment of the principal of, or interest on, any Public External Indebtedness (as defined below) of, or guaranteed by, the Issuer, the
Guarantor or any of the Guarantor’s Material Subsidiaries or the Subsidiary Guarantors or any of them or any of their respective Material Subsidiaries, in an aggregate principal amount exceeding U.S. $40,000,000 or its equivalent, when and as
the same shall become due and payable, if such default shall continue for more than the period of grace, if any, originally applicable thereto; or 
  

 R-7 








 (d) Enforcement Proceedings: a distress or execution or other legal process
is levied or enforced or sued out upon or against any substantial part of the property, assets or revenues of the Issuer, the Guarantor or any of the Guarantor’s Material Subsidiaries or the Subsidiary Guarantors or any of them or any of their
respective Material Subsidiaries and is not discharged or stayed within 60 days of having been so levied, enforced or sued out; or 
  
 (e) Security Enforced: an encumbrancer takes possession or a receiver, manager or other similar officer is appointed of the
whole or any substantial part of the undertaking, property, assets or revenues of the Issuer, the Guarantor or any of the Guarantor’s Material Subsidiaries or the Subsidiary Guarantors or any of them or any of their respective Material
Subsidiaries; or 
  
 (f) Insolvency: the
Issuer, the Guarantor or any of the Guarantor’s Material Subsidiaries or the Subsidiary Guarantors or any of them or any of their respective Material Subsidiaries becomes insolvent or is generally unable to pay its debts as they mature or
applies for or consents to or suffers the appointment of an administrator, liquidator, receiver or similar officer of the Issuer, the Guarantor or any of the Guarantor’s Material Subsidiaries or the Subsidiary Guarantors or any of them or any
of their respective Material Subsidiaries or the whole or any substantial part of the undertaking, property, assets or revenues of the Issuer, the Guarantor or any of the Guarantor’s Material Subsidiaries or the Subsidiary Guarantors or any of

 (g) Winding-up: an order is made or an
