Hampshire constitutes a finding by the Secretary of State of New Hampshire that any document filed under
RSA 421-B is true, complete and not misleading. Neither any such fact nor the fact that an exemption or
exception is available for a security or a transaction means that the Secretary of State has passed in any way
upon the merits or qualifications of, or recommended or given approval to, any person, security, or
transaction. It is unlawful to make, or cause to be made, to any prospective purchaser, customer, or client
any representation inconsistent with the provisions of this paragraph.

References in this Offering Circular to "Euros" or "" are to the lawful currency of the European Economic and
Monetary Union. References in this Offering Circular to "U.S. dollars", "U.S. $", "dollars" or "$" are to the lawful
currency of the United States of America. References in this Offering Circular to "pesos" or "Ps." are to the lawful
currency of Mexico. We use the term "billion" in this Offering Circular to mean one thousand million.
This Offering Circular contains translations of certain peso amounts into U.S. dollars at specified rates solely for
your convenience. You should not construe these translations as representations that the peso amounts actually
represent the actual U.S. dollar amounts or could be converted into U.S. dollars at the rate indicated. Unless we
indicate otherwise, the U.S. dollar amounts have been translated from pesos at an exchange rate of Ps. 9.1423 to
U.S. $1.00, which is the exchange rate that the Ministry of Finance and Public Credit gave to Petróleos Mexicanos
on December 31, 2001.
On April 2, 2003, the U.S. dollar noon buying rate for cable transfers in New York reported by the Federal Reserve
Bank of New York was Ps. 10.6730 = U.S. $1.00.

Presentation of Financial Information
The Issuer does not prepare separate financial statements; its results are consolidated with those of PEMEX, which
maintains its financial statements and records in nominal pesos. The Issuer, the Guarantor and the Subsidiary
Guarantors believe that separate financial statements of the Issuer would not be material to you because (i) the
Guarantor is an SEC reporting company and controls the Issuer, (ii) the Issuer has no independent operations, and
(iii) the Guarantor has fully and unconditionally guaranteed the Issuer's obligations under the Notes and the
Subsidiary Guarantors have, jointly and severally, unconditionally guaranteed the Guarantor's obligations under the
Guarantee and Subsidiary Guaranties (as defined below).
The audited consolidated financial statements of PEMEX as of December 31, 2001 and 2000 and for each of the
three years in the period ended December 31, 2001 (the "2001 Financial Statements") are included in Item 18 of the
2001 Form 20-F of Petróleos Mexicanos, which is included in this Offering Circular at Annex A. We also include
unaudited condensed consolidated financial statements of PEMEX as of June 30, 2002 and for the six-month periods
ended June 30, 2001 and 2002 (the "Interim Financial Statements"), which is included in this Offering Circular at
Annex B. The 2001 Financial Statements and the Interim Financial Statements were prepared in accordance with
accounting principles generally accepted in Mexico, or "Mexican GAAP," and as to the recognition of inflation, in
accordance with the guidelines established in Financial Reporting Standard NIF-06 BIS "A," section A. Notes 2 b)
and 15 to the 2001 Financial Statements describe the inflation accounting rules that apply to PEMEX. Mexican
GAAP differs in certain significant respects from United States generally accepted accounting principles ("U.S.
GAAP"). The differences that are material to the 2001 Financial Statements and to the Interim Financial Statements
are described in Note 19 to the 2001 Financial Statements and Note 12 to the Interim Financial Statements. We also
include summary financial data for the eleven months ended November 30, 2002 of Petróleos Mexicanos, the
Subsidiary Entities and the Pemex Project Funding Master Trust, but excluding the Subsidiary Companies, which is
not audited and was prepared in accordance with Mexican GAAP, except as to the recognition of inflation, which is
in accordance with the guidelines established in NIF-06 BIS "A," section A.

Forward-Looking Statements
This Offering Circular contains forward-looking statements. Statements that are not historical facts, including
statements about our beliefs and expectations, are forward-looking statements. We have based these statements on
current plans, estimates and projections and you should therefore not place undue reliance on them. Forward-
looking statements speak only as of the date they are made, and we undertake no obligation to update publicly any
of them in light of new information or future events. Forward-looking statements involve inherent risks and
uncertainties.

For a discussion of important factors that could cause actual results to differ materially from those contained in any
forward-looking statement, you should read "Risk Factors" below.

Selected Financial Data
The selected financial data set forth below should be read in conjunction with, and are qualified in their entirety by
reference to, the audited 2001 Financial Statements and the unaudited Interim Financial Statements of PEMEX,
included in this Offering Circular as Annexes A and B, respectively. The selected financial data set forth below as
of the five years ended December 31, 2001 and as of June 30, 2002 have been derived from the consolidated
financial statements of PEMEX for the years ended December 31, 1997 and 1998 (which are not included herein),
the consolidated financial statements of PEMEX for the years ended December 31, 1999, 2000 and 2001 and the
Interim Financial Statements of PEMEX for the six-month periods ended June 30, 2001 and 2002. The consolidated
financial statements of PEMEX for the years ended December 31, 1999 and 2000 were audited by Mancera, S.C. (A
Member Practice of Ernst & Young Global), and the consolidated financial statements of PEMEX for the year ended
December 31, 2001 were audited by PricewaterhouseCoopers, S.C. See Annex A "Item 5Operating and Financial
Review and ProspectsChange in Independent Auditors." The Interim Financial Statements of PEMEX as of June
30, 2002 and for the six-month periods ended June 30, 2001 and 2002 have not been audited.
The consolidated financial statements are prepared in accordance with Mexican GAAP and, as to the recognition of
inflation, in accordance with the guidelines established in Financial Reporting Standard NIF-06 BIS "A," section A.
See Notes 2 b) and 15 to the 2001 Financial Statements for a discussion of the inflation accounting rules applicable
to PEMEX. Mexican GAAP differs in certain significant respects from U.S. GAAP. The most important of the
material items generating a difference between operating results under U.S. GAAP and Mexican GAAP are the
accounting methodologies for the treatment of exploration and drilling costs, pension premiums and post-retirement
benefit obligations, financial instruments, inflation, foreign exchange losses, capitalized interest and depreciation
and impairment of fixed assets, which are described in Note 19 to the 2001 Financial Statements included in Annex
A and Note 12 to the Interim Financial Statements included in Annex B.
For a further discussion of the accounting principles applicable to PEMEX, see Annex A "Item 3--Key
InformationSelected Financial Data," Annex A "Item 5--Operating and Financial Review and Prospects--U.S.
GAAP Reconciliation," and Note 12 to the Interim Financial Statements included in Annex B.

section A, which is different from Mexican GAAP Bulletin B-10. Mexican GAAP differs from U.S. GAAP. The most important of the material
differences between U.S. GAAP and Mexican GAAP affecting PEMEX are the accounting treatment of: (1) exploration and drilling costs, (2)
pensions and post-retirement obligations, (3) financial instruments, (4) inflation, (5) foreign exchange losses, (6) capitalized interest, (7)

million for 1999, Ps. 624 million for 2000, Ps. 10,857 million for 2001, Ps. 3,833 million for the six-month period ended June 30, 2001 and
Ps. 8,023 million for the six-month period ended June 30, 2002. Under Mexican GAAP, earnings for the years ended December 31, 1998, 1999,
2000 and 2001, and for the six-month periods ended June 30, 2001 and 2002, were insufficient to cover fixed charges. The amount by which fixed

PEMEX does not currently prepare comprehensive price-level adjusted financial statements in accordance with
Bulletin B-10, "Recognition of the Effects of Inflation on Financial Information," under Mexican GAAP. For the
years ended December 31, 1997 and 1998, Mexico was deemed to be a hyperinflationary economy. Pursuant to
Rule 3-20(c) of Regulation S-X promulgated by the U.S. Securities and Exchange Commission, unaudited selected
financial data prepared on the basis of price-level adjusted financial information for these years has been included
reflecting the impact of U.S. GAAP adjustments and reclassifications. For the years ended December 31, 1999,
2000 and 2001, and for the six-month periods ended June 30, 2001 and 2002, Mexico was not considered a
hyperinflationary economy. However, supplemental unaudited price-level adjusted financial information for these
subsequent years has been provided in lieu of a comprehensive price-level adjustment that would result from
PEMEX's adoption of Bulletin B-10. In the opinion of PEMEX management, all adjustments that are necessary for
a fair presentation of the price-level adjusted financial information have been included herein. This unaudited price-
level adjusted financial data is derived from the supplemental price-level adjusted financial information included
elsewhere in this Offering Circular and should also be read in conjunction the 2001 Financial Statements and
Condensed Consolidated Financial Statements for the six-month periods ended June 30, 2001 and 2002.

Risk Factors

Risk Factors Related to the Operations of PEMEX
Crude oil prices are volatile, and low oil prices negatively affect PEMEX's income.
International crude oil prices fluctuate due to many factors, including:
changes in global supply and demand for crude oil and refined petroleum products;
availability and price of competing commodities;
international economic trends;
currency exchange fluctuations;
expectations of inflation;
actions of commodity markets participants;
domestic and foreign government regulations; and
political events in major oil producing and consuming nations.
PEMEX has no control over these factors. Historically, the weighted average price of the crude oil that PEMEX
exports has fluctuated from a high of U.S. $26.82 per barrel in 1984 to a low of U.S. $15.55 per barrel in 1999. In
2002, the weighted average price of PEMEX's crude oil exports was U.S. $21.58 per barrel, 16% higher than the
weighted average price during 2001. On March 26, 2003, the weighted average spot price of PEMEX crude oil was
U.S. $21.17.
When international crude oil and natural gas prices are low, PEMEX earns less export sales revenue, and, therefore,
lower income because its costs remain roughly constant. Conversely, when crude oil and natural gas prices are high,
PEMEX earns more export sales revenue and its income increases. As a result, future fluctuations in international
crude oil prices will directly affect PEMEX's results of operations and financial condition.
Decreases in PEMEX's estimates from time to time of Mexico's hydrocarbon reserves could reduce PEMEX's
potential future income.
The reserve data set forth in Annex A and under "Recent Developments" represent only estimates. Estimating
quantities of proved hydrocarbon reserves and projecting future rates of production and timing of development
expenditures is an inexact process and is subject to many factors beyond PEMEX's control. The accuracy of any
reserve estimate depends on the quality of available data and engineering and geological interpretation and
judgment. As a result, estimates of different engineers may vary. Additionally, the results of drilling, testing and
production subsequent to the date of an estimate may justify revision of an estimate. Therefore, proved reserve
estimates may be materially different from the quantities of crude oil and natural gas that PEMEX can ultimately
recover.
Pemex-Exploration and Production revises its estimates of Mexico's hydrocarbon reserves annually. This process
may result in material revisions to PEMEX's estimates of Mexico's hydrocarbon reserves.

PEMEX is an integrated oil and gas company and is exposed to production, equipment and transportation risks.
PEMEX is subject to production, equipment and transportation risks that are common among oil and gas companies.
For example, PEMEX encounters:
production risk--i.e., risk related to fluctuations in production that may be affected by reserve levels,
accidents, mechanical difficulties, adverse natural conditions, such as bad weather and other acts of
God, as well as the inability to manage unforeseen production costs;
equipment risk--i.e., risk related to adequacy and condition of the production facilities, including
equipment becoming obsolete; and
transportation risk--i.e., risk related to the condition of pipelines and vulnerability of other modes of
transportation.
In particular, PEMEX's business is subject to the risk of:
pipeline explosions (oil or natural gas);
explosions in refineries, petrochemical plants, storage and distribution terminals or buoys and
monobuoys;
hurricanes in the Gulf of Mexico;
unexpected geological formations or pressures;
blow outs, which are sudden, violent explosions of oil, natural gas or water from a drilling well,
followed by an uncontrolled flow from the well;
fires and cratering, which is the caving in and collapse of the earth's structure around a blow out well;
and
mechanical failures and collapsed holes, particularly in horizontal wellbores.
The occurrence of any of these events could result in:
personal injuries or loss of life;
environmental damage and the necessary clean-up costs and expenses; or
other damage to PEMEX's property or the property of others.
In accordance with customary industry practice, PEMEX has purchased insurance policies covering some of these
risks. However, these policies do not cover all potential liabilities that may result from these risks. In addition,
insurance is not available for some of these risks. See Annex A "Item 4--Information on the Company--Business
Overview--PEMEX Corporate Matters--Insurance."
