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 6.625% Guaranteed Bonds due 2035 (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. $1,249,000,000 principal amount of
6.625% Guaranteed Bonds due 2035 issued by the Issuer on February 13, 2006 and December 7, 2006.
This further issuance is initially limited to U.S. $501,000,000 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,
dated June 8, 2005, February 2, 2006 and October 22, 2007 (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. $10,000
and integral multiples of U.S. $1,000 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,




R-1 









 




at the interest rate per annum specified on the face hereof, until the principal hereof has
been 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 in U.S. dollars 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




R-2 









 




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 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) In the event of a redemption of Bonds in part (if permitted by the provisions hereof),
the Issuer shall not be required (i) to register the transfer of or exchange any Bond during a
period beginning at the opening of business 15 days before, and continuing until, the date on which
notice is given identifying the Bonds to be redeemed, or (ii) to register the transfer of or
exchange any Bond, or portion thereof, called for redemption.




          (e) 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.




R-3 









 








          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.




          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




R-4 









 




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 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




R-5 









 




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 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) This Bond may not be redeemed prior to the Stated Maturity, except as specified in
paragraphs (b) and (c) below.




          (b) 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




R-6 









 




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 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.




          (c) The Bonds 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 (the “Redemption Price”) equal to the sum of (A) 100% of the principal amount of
such Bonds and (B) the Make-Whole Amount (as defined below), plus accrued interest on the principal
amount of the Bonds to the date of redemption (the “Redemption Date”). “Make-Whole Amount” means
the excess of (A) the sum of the present values of each of the remaining scheduled payments of
principal and interest on the Bonds (exclusive of interest accrued to the Redemption Date)
discounted to the Redemption Date on a semiannual basis (assuming a 360-day year consisting of
twelve 30-day months) at the Treasury Rate (as defined below) plus 50 basis points over (ii) the
principal amount of such Bonds. “Treasury Rate” means, with respect to any Redemption Date, the
rate per annum equal to the semiannual equivalent yield to maturity or interpolated maturity of the
Comparable Treasury Issue (as defined below), assuming a price for the Comparable Treasury Issue
(expressed as a percentage of its principal amount) equal to the Comparable Treasury Price for such
Redemption Date. “Comparable Treasury Issue” means the United States Treasury security or
