Petróleos Mexicanos and its four subsidiary entities, Pemex-Exploración y Producción (Pemex-Exploration and Production), Pemex-Refinación (Pemex-Refining), Pemex-Gas y Petroquímica Básica (Pemex-Gas and Basic Petrochemicals) and Pemex-Petroquímica (Pemex-Petrochemicals and together with Pemex-Exploration and Production, Pemex-Refining and Pemex-Gas and Basic Petrochemicals, collectively referred to as the subsidiary entities), comprise the state oil and gas company of the United Mexican States, which we refer to as Mexico. Each of Petróleos Mexicanos and the subsidiary entities is a decentralized public entity of the Federal Government of Mexico, which we refer to as the Mexican Government, and is a legal entity empowered to own property and carry on business in its own name. In addition, a number of subsidiary companies that are defined in Note 2 and listed in Note 3(b) to our consolidated financial statements incorporated in Item 18, including the Pemex Project Funding Master Trust (which we refer to as the Master Trust) and Fideicomiso Irrevocable de Administración No. F/163 (which we refer to as Fideicomiso F/163) (which are described below under “Item 5—Operating and Financial Review and Prospects—Liquidity and Capital Resources—Commitments for Capital Expenditures and Sources of Funding”), are incorporated into the consolidated financial statements; these subsidiary companies are also identified with the corresponding ownership percentages in “—Consolidated Structure of PEMEX” on page 3. Petróleos Mexicanos, the subsidiary entities and the subsidiary companies are collectively referred to as “PEMEX” or “we.”

References herein to “U.S. $,” “$,” “U.S. dollars” or “dollars” are to United States dollars. References herein to “pesos” or “Ps.” are to the legal currency of Mexico. References herein to “euros” or “€” are to the legal currency of the European Economic and Monetary Union. References herein to “pounds” or “£” are to the legal currency of the United Kingdom. References herein to “Swiss Francs” or “CHF” are to the legal currency of the Swiss Confederation. References herein to “Japanese yen” or “¥” are to the legal currency of Japan. The term “billion” as used herein means one thousand million.

We maintain our consolidated financial statements and records in pesos. Unless otherwise indicated, we have translated all peso amounts to U.S. dollars in this Form 20-F, including all convenience translations of our consolidated financial statements included herein, at an exchange rate of Ps. 13.0587 = U.S. $1.00, which is the exchange rate that Secretaría de Hacienda y Crédito Público (Ministry of Finance and Public Credit, or the SHCP) instructed us to use on December 31, 2009. You should not construe these translations from pesos into dollars as actually representing such U.S. dollar amounts or meaning that you could convert such amounts into U.S. dollars at the rates indicated. The peso has depreciated substantially in relation to the U.S. dollar since the end of 1994, when the Mexican Government allowed the peso to float freely against the U.S. dollar and the Mexican Government established a broad economic reform program in response to these and other events. Due to the volatility of the peso/dollar exchange rate, the exchange rate on any date subsequent to the date hereof could be materially different from the rate indicated above. See “Item 3—Key Information—Exchange Rates” for information regarding the rates of exchange between pesos and U.S. dollars.

FORWARD-LOOKING STATEMENTS

This Form 20-F contains words, such as “believe,” “expect,” “anticipate” and similar expressions that identify forward-looking statements, which reflect our views about future events and financial performance. We have made forward-looking statements that address, among other things, our:

• drilling and other exploration activities;

• import and export activities;

• projected and targeted capital expenditures and other costs, commitments and revenues; and

• liquidity.

Actual results could differ materially from those projected in such forward-looking statements as a result of various factors that may be beyond our control. These factors include, but are not limited to:

• changes in international crude oil and natural gas prices;

• effects on us from competition;

• limitations on our access to sources of financing on competitive terms;

• significant developments in the global economy;

• significant economic or political developments in Mexico;

• developments affecting the energy sector; and

• changes in our regulatory environment.

Accordingly, you should not place undue reliance on these forward-looking statements. In any event, these statements speak only as of their dates, and we undertake no obligation to update or revise any of them, whether as a result of new information, future events or otherwise.

For a discussion of important factors that could cause actual results to differ materially from those contained in any forward-looking statement, you should see “Item 3—Key Information—Risk Factors.”

PRESENTATION OF INFORMATION CONCERNING RESERVES

The estimates of Mexico’s proved reserves of crude oil and natural gas for the five years ended December 31, 2009 included in this annual report have been calculated according to the technical definitions required by the U.S. Securities and Exchange Commission, or SEC. Although DeGolyer and MacNaughton, Netherland, Sewell International, S. de R.L. de C.V. and Ryder Scott Company, L.P. reviewed our estimates of the hydrocarbon reserves of Mexico as of December 31, 2009, all reserves estimates involve some degree of uncertainty. See “Item 3—Key Information—Risk Factors—Risk Factors Related to the Relationship between PEMEX and the Mexican Government—The Mexican nation, not PEMEX, owns the hydrocarbon reserves in Mexico,” and “—Information on Mexico’s hydrocarbon reserves is based on estimates, which are uncertain and subject to revision” for a description of the risks relating to reserves and reserves estimates.

SELECTED FINANCIAL DATA

The selected financial data set forth below should be read in conjunction with our consolidated financial statements included in Item 18.

The selected financial data set forth below as of and for the five years ended December 31, 2009 have been derived from our consolidated financial statements for the years ended December 31, 2005 and 2006, which are not included herein, and the consolidated financial statements of PEMEX for the years ended December 31, 2007, 2008 and 2009, which were audited by KPMG Cárdenas Dosal, S.C., an independent registered public accounting firm, for the 2007, 2008 and 2009 fiscal years and by PricewaterhouseCoopers, S.C., an independent registered public accounting firm, for the two previous years.

Our consolidated financial statements for the year ended December 31, 2005 were prepared in accordance with Mexican Generally Accepted Accounting Principles, which we refer to as Mexican GAAP. Our consolidated financial statements for the years ended December 31, 2006, 2007, 2008 and 2009 were prepared in accordance with Normas de Información Financiera Mexicanas (Mexican Financial Reporting Standards, or Mexican FRS or NIFs), which replaced Mexican GAAP, although this change had no accounting implications for PEMEX in 2006, 2007, 2008 or 2009. In this document, unless otherwise stated, we use the term Mexican FRS to mean (1) Mexican GAAP for periods ending prior to January 1, 2006 and (2) NIFs for periods ending on or after January 1, 2006.

Beginning January 1, 2003, we recognized the effects of inflation in accordance with Governmental Standard GS-06 BIS “A” Section C, which required the adoption of Bulletin B-10, “Recognition of the Effects of Inflation on Financial Information,” under Mexican FRS (which we refer to as Bulletin B-10). As a result of the provisions of Bulletin B-10, we restated our consolidated financial statements for the years ended December 31, 2005 and 2006, in order to present our results for each of these years on the same basis and purchasing power as the results for the year ended December 31, 2007 with respect to the recognition of the effects of inflation. Consequently, the amounts shown in our consolidated financial statements for the years then ended are expressed in thousands of constant Mexican pesos as of December 31, 2007. The December 31, 2007 restatement factors applied to the financial statements at December 31, 2005 and 2006 were 1.0405 and 1.0376, respectively, which correspond to inflation from January 1, 2006 and 2007 through December 31, 2007, respectively, based on the national consumer price index (NCPI).

In accordance with FRS B-10 “Effects of Inflation” (which we refer to as FRS B-10), because the economic environment in the three-year periods ended December 31, 2007 and 2008 did not qualify as inflationary (because accumulated inflation for such periods was below 26%), we did not use inflation accounting to prepare our consolidated financial statements as of December 31, 2008 and 2009. As a result, amounts in this report are presented in nominal terms; however, such amounts do reflect inflationary effects recognized up to December 31, 2007. See Note 3(a) to our consolidated financial statements included herein for a summary of the effects of application of FRS B-10 and Notes 3(h), 3(p), 3(q), 3(u) and 3(v) to our consolidated financial statements included herein for discussion of the inflation accounting rules applied prior to the adoption of FRS B-10.

In addition to the above, our consolidated financial statements for the years ended December 31, 2005, 2006, 2007 and 2008 have been reclassified in certain accounts with the purpose of making them comparable with our consolidated financial statements as of December 31, 2009.

Mexican FRS differ in certain significant respects from United States Generally Accepted Accounting Principles (which we refer to as U.S. GAAP). The principal differences between our net income and equity under U.S. GAAP and Mexican FRS are described in Note 21 to our consolidated financial statements included herein and in “Item 5—Operating and Financial Review and Prospects—U.S. GAAP Reconciliation.”

RISK FACTORS

Risk Factors Related to the Operations of PEMEX

Crude oil and natural gas prices are volatile, and low crude oil and natural gas prices negatively affect PEMEX’s income and cash flows and the amount of Mexico’s hydrocarbon reserves.

International crude oil and natural gas prices are subject to global supply and demand and fluctuate due to many factors beyond our control. These factors include competition within the oil and natural gas industry, the prices and availability of alternative sources of energy, international economic trends, exchange rate fluctuations, expectations of inflation, domestic and foreign government regulations or international laws, political and other events in major oil and natural gas producing and consuming nations and actions taken by Organization of the Petroleum Exporting Countries (OPEC) members and other oil exporting countries, trading activity in oil and natural gas and transactions in derivative financial instruments (which we refer to as DFIs) related to oil and gas.

When international crude oil and natural gas prices are low, we earn less export sales revenue and, therefore, generate lower cash flows and earn less income, because our costs remain roughly constant. Conversely, when crude oil and natural gas prices are high, we earn more export sales revenue and our income before taxes and duties increases. As a result, future fluctuations in international crude oil and natural gas prices will have a direct effect on our results of operations and financial condition, and may affect Mexico’s hydrocarbon reserves estimates. See “—Risk Factors Related to the Relationship between PEMEX and the Mexican Government—Information on Mexico’s hydrocarbon reserves is based on estimates, which are uncertain and subject to revisions” and “Item 11—Quantitative and Qualitative Disclosures about Market Risk—Commodity Price Risk.”

PEMEX is an integrated oil and gas company and is exposed to production, equipment and transportation risks and deliberate acts of terror.

We are subject to several risks that are common among oil and gas companies. These risks include production risks (fluctuations in production due to operational hazards, natural disasters or weather, accidents, etc.), equipment risks (relating to the adequacy and condition of our facilities and equipment) and transportation risks (relating to the condition and vulnerability of pipelines and other modes of transportation). More specifically, our business is subject to the risks of explosions in pipelines, refineries, plants, drilling wells and other facilities, hurricanes in the Gulf of Mexico and other natural or geological disasters and accidents, fires, mechanical failures and theft.

Our facilities are also subject to the risk of sabotage and terrorism. In July 2007, two of our pipelines were attacked. In September 2007, six different sites were attacked and 12 of our pipelines were affected. During 2008, 2009 and as of the date of this report in 2010, there have been no further acts of sabotage and terrorism. However, the occurrence of any of these events or of accidents connected with production, processing and transporting oil and oil products could result in personal injuries, loss of life, environmental damage with resulting containment, clean-up and repair expenses, equipment damage and damage to our facilities. A shutdown of the affected facilities could disrupt our production and increase our production costs.

Although we purchase comprehensive insurance policies covering most of these risks, these policies may not cover all liabilities, and insurance may not be available for some of the consequential risks. There can be no assurance that accidents or acts of terror will not occur in the future, that insurance will adequately cover the entire scope or extent of our losses or that we may not be found directly liable in connection with claims arising from these and other events. See “Item 4—Information on the Company—Business Overview—PEMEX Corporate Matters—Insurance.”

PEMEX has a substantial amount of liabilities that could adversely affect our financial health and results of operations.

We have a substantial amount of debt. As of December 31, 2009, our total indebtedness, excluding accrued interest, was approximately U.S. $47.9 billion, in nominal terms, which is an 11.9% increase, as compared to our

7

total indebtedness, excluding accrued interest, of U.S. $42.8 billion at December 31, 2008. Our level of debt may increase further in the near or medium term and may have an adverse effect on our financial condition and results of operations.

To service our debt, we have relied and may continue to rely on a combination of cash flows provided by operations, drawdowns under our available credit facilities and the incurrence of additional indebtedness. Certain rating agencies have expressed concerns regarding the total amount of our debt, our increase in indebtedness over the last several years and our substantial unfunded reserve for retirement pensions and seniority premiums, which as of December 31, 2009 was equal to approximately U.S. $44.1 billion. Due to our heavy tax burden, we have resorted to financings to fund our capital investment projects. Any further lowering of our credit ratings may have adverse consequences on our ability to access the financial markets and/or our cost of financing. Similarly, any further lowering of the credit ratings of Mexico may have an adverse effect on our credit ratings. See “Item 5—Operating and Financial Review and Prospects—Liquidity and Capital Resources—Commitments for Capital Expenditures and Sources of Funding” and “Item 4—Information on the Company—United Mexican States—Public Debt—Rating Agency Considerations.” If we are unable to obtain financing on favorable terms, this may hamper our ability to obtain further financing as well as hamper investment in downstream facilities financed through debt. As a result, we may not be able to make the capital expenditures needed to maintain our current production levels and to maintain, as well as increase, Mexico’s hydrocarbon reserves, which may adversely affect our financial health and results of operations. See “—Risk Factors Related to the Relationship between PEMEX and the Mexican Government—PEMEX must make significant capital expenditures to maintain its current production levels, and to maintain, as well as increase, Mexico’s hydrocarbon reserves. Mexican Government budget cuts, reductions in PEMEX’s income and inability to obtain financing may limit PEMEX’s ability to make capital investments” and “—Considerations Related to Mexico—The current global financial crisis has led to lower oil prices and a lack of available credit; if the crisis continues or worsens, it could adversely affect our results of operations, financial condition and cash flows” below.

PEMEX’s compliance with environmental regulations in Mexico could result in material adverse effects on its results of operations.

A wide range of general and industry-specific Mexican federal and state environmental laws and regulations apply to our operations. Numerous Mexican Government agencies and departments issue environmental rules and regulations, which are often difficult and costly to comply with and which carry substantial penalties for non-compliance. This regulatory burden increases our costs because it requires us to make significant capital expenditures and limits our ability to extract hydrocarbons, resulting in lower revenues. For an estimate of our accrued environmental liabilities, see “Item 4—Information on the Company—Environmental Regulation—Environmental Liabilities.” In addition, we have agreed with third parties to make investments to reduce our carbon emissions. See “Item 4—Information on the Company—Environmental Regulation—Carbon Dioxide Emissions Reduction.”

PEMEX publishes less U.S. GAAP financial information than U.S. companies are required to file with the SEC.

We prepare our financial statements according to Mexican FRS, which differ in certain significant respects from U.S. GAAP. See “Item 3—Key Information—Selected Financial Data,” “Item 5—Operating and Financial Review and Prospects—U.S. GAAP Reconciliation” and Note 21 to our consolidated financial statements included herein. As a foreign issuer, we are not required to prepare quarterly U.S. GAAP financial information, and we therefore generally prepare a reconciliation of our net income and equity under Mexican FRS to U.S. GAAP as well as explanatory notes and additional disclosure required under U.S. GAAP on a yearly basis only. As a result, there may be less or different publicly available information about us than there is about U.S. issuers.

8

If PEMEX were unable to properly adopt and implement International Financial Reporting Standards, its ability to produce and publish timely and accurate financial information could be materially affected.

Beginning with the fiscal year starting January 1, 2012, Mexican issuers with securities registered in the Registro Nacional de Valores (National Securities Registry) of the Comisión Nacional Bancaria y de Valores (which we refer to as the CNBV) will be required to prepare financial statements in accordance with International Financial Reporting Standards as issued by the International Accounting Standards Board (IFRS). In connection with this implementation, we will be required to evaluate our internal controls over financial reporting in order to verify that they will continue to be effective once the implementation of IFRS is complete. As of the date of this report, we are in the process of implementing IFRS and expect to fulfill this requirement. However, we cannot be certain that no event will occur which could prevent us from adopting, by the deadline established by the CNBV, the modifications necessary to issue our financial statements under IFRS. If we were not able to implement IFRS by the date required, our ability to issue timely and accurate financial information could be materially affected. Consequently, we could be subject to penalties for such non-compliance, including having our securities delisted from the Bolsa Mexicana de Valores, S.A.B. de C.V (which we refer to as the BMV).

Risk Factors Related to the Relationship between PEMEX and the Mexican Government

The Mexican Government controls PEMEX and it could limit PEMEX’s ability to satisfy its external debt obligations or could reorganize or transfer PEMEX or its assets.

Petróleos Mexicanos is a decentralized public entity of the Mexican Government, and therefore the Mexican Government controls us, as well as our annual budget, which is approved by the Mexican Congress. However, our financing obligations do not constitute obligations of and are not guaranteed by the Mexican Government. The Mexican Government has the power to intervene directly or indirectly in our commercial and operational affairs. Intervention by the Mexican Government could adversely affect our ability to make payments under any securities issued or guaranteed by us.

The Mexican Government’s agreements with international creditors may affect our external debt obligations. In certain past debt restructurings of the Mexican Government, Petróleos Mexicanos’ external indebtedness was treated on the same terms as the debt of the Mexican Government and other public sector entities. In addition, Mexico has entered into agreements with official bilateral creditors to reschedule public sector external debt. Mexico has not requested restructuring of bonds or debt owed to multilateral agencies.

The Mexican Government would have the power, if federal law and the Constitución Política de los Estados Unidos Mexicanos (Political Constitution of the United Mexican States) were amended, to reorganize PEMEX, including a transfer of all or a portion of Petróleos Mexicanos and the subsidiary entities or their assets to an entity not controlled by the Mexican Government. Such a reorganization or transfer could adversely affect production, cause a disruption in our workforce and our operations, and cause us to default on certain obligations. See also “—Considerations Related to Mexico” below.

Petróleos Mexicanos and the subsidiary entities pay special taxes, duties and dividends to the Mexican Government, which may limit PEMEX’s capacity to expand its investment program.

The Mexican Government taxes PEMEX heavily, particularly the revenues of Pemex-Exploration and Production, which may limit PEMEX’s ability to make capital investments. In 2009, approximately 50.2% of the sales revenues of PEMEX was used to pay taxes to the Mexican Government. These special taxes, duties and dividends constitute a substantial portion of the Mexican Government’s revenues. For further information, see “Item 4—Information on the Company—Taxes and Duties” and “Item 5—Operating and Financial Review and Prospects—IEPS Tax, Hydrocarbon Duties and Other Taxes.”

The Mexican Government has entered into agreements with other nations to limit production.

Although Mexico is not a member of OPEC, in the past it has entered into agreements with OPEC and non-OPEC countries to reduce global crude oil supply. We do not control the Mexican Government’s

9

international affairs and the Mexican Government could agree with OPEC or other countries to reduce our crude oil production or exports in the future. A reduction in our oil production or exports could reduce our revenues.

The Mexican Government has imposed price controls in the domestic market on PEMEX’s products.

The Mexican Government has from time to time imposed price controls on the sales of natural gas, liquefied petroleum gas (LPG), gasoline, diesel, domestic gas oil and fuel oil number 6, among others. As a result of these price controls, PEMEX has not been able to pass on all of the increases in the prices of its product purchases to its customers in the domestic market. We do not control the Mexican Government’s domestic policies and the Mexican Government could impose additional price controls on the domestic market in the future. The imposition of such price controls would adversely affect our results of operations. For more information, see “Item 4—Information on the Company—Business Overview—Refining—Pricing Decrees” and “Item 4—Information on the Company—Business Overview—Gas and Basic Petrochemicals—Pricing Decrees.”

The Mexican nation, not PEMEX, owns the hydrocarbon reserves in Mexico.

The Political Constitution of the United Mexican States provides that the Mexican nation, not PEMEX, owns all petroleum and other hydrocarbon reserves located in Mexico. Although Mexican law gives Pemex-Exploration and Production the exclusive right to exploit Mexico’s hydrocarbon reserves, it does not preclude the Mexican Congress from changing current law and assigning some or all of these rights to another company. Such an event would adversely affect our ability to generate income.

Information on Mexico’s hydrocarbon reserves is based on estimates, which are uncertain and subject to revisions.

The information on oil, gas and other reserves set forth in this Form 20-F is based on estimates. Reserves valuation is a subjective process of estimating underground accumulations of crude oil and natural gas that cannot be measured in an exact manner; the accuracy of any reserves estimate depends on the quality and reliability of available data, engineering and geological interpretation and subjective judgment. Additionally, estimates may be revised based on subsequent results of drilling, testing and production. These estimates are also subject to certain adjustments based on changes in variables, including crude oil prices. Therefore, proved reserves estimates may differ materially from the ultimately recoverable quantities of crude oil and natural gas. See “—Risk Factors Related to the Operations of PEMEX—Crude oil and natural gas prices are volatile, and low crude oil and natural gas prices negatively affect PEMEX’s income and cash flows and the amount of Mexico’s hydrocarbon reserves.” Pemex-Exploration and Production revises its estimates of Mexico’s hydrocarbon reserves annually, which may result in material revisions to our estimates of Mexico’s hydrocarbon reserves.

PEMEX must make significant capital expenditures to maintain its current production levels, and to maintain, as well as increase, Mexico’s proved hydrocarbon reserves. Mexican Government budget cuts, reductions in PEMEX’s income and inability to obtain financing may limit PEMEX’s ability to make capital investments.

We invest funds to maintain, as well as increase, the amount of extractable hydrocarbon reserves in Mexico. We also continually invest capital to enhance our hydrocarbon recovery ratio and improve the reliability and productivity of our infrastructure. While the replacement rate for proved hydrocarbon reserves has increased in recent years, from 50.3% in 2007 to 71.8% in 2008 and to 77.1% in 2009, the overall replacement rate is still less than 100%, which represents a decline in Mexico’s proved hydrocarbon reserves. Pemex-Exploration and Production’s crude oil production decreased by 5.5% from 2006 to 2007, by 9.2% from 2007 to 2008 and by 6.8% from 2008 to 2009, primarily as a result of the decline of production in the Cantarell complex. Our ability to make capital expenditures is limited by the substantial taxes that we pay to the Mexican Government and cyclical decreases in our revenues primarily related to lower oil prices. In addition, budget cuts imposed by the Mexican Government and the availability of financing may also limit our ability to make capital investments. For more information, see “Item 4—Information on the Company—History and Development—Capital Expenditures and Investments.”

PEMEX may claim some immunities under the Foreign Sovereign Immunities Act and Mexican law, and your ability to sue or recover may be limited.

Petróleos Mexicanos and the subsidiary entities are decentralized public entities of the Mexican Government. Accordingly, you may not be able to obtain a judgment in a U.S. court against us unless the U.S. court determines that we are not entitled to sovereign immunity with respect to that action. In addition, Mexican law does not allow attachment prior to judgment or attachment in aid of execution upon a judgment by Mexican courts upon the assets of Petróleos Mexicanos or the subsidiary entities. As a result, your ability to enforce judgments against us in the courts of Mexico may be limited. We also do not know whether Mexican courts would enforce judgments of U.S. courts based on the civil liability provisions of the U.S. federal securities laws. Therefore, even if you were able to obtain a U.S. judgment against us, you might not be able to obtain a judgment in Mexico that is based on that U.S. judgment. Moreover, you may not be able to enforce a judgment against our property in the United States except under the limited circumstances specified in the Foreign Sovereign Immunities Act of 1976, as amended. Finally, if you were to bring an action in Mexico seeking to enforce our obligations under any of our securities, satisfaction of those obligations may be made in pesos, pursuant to the laws of Mexico.

PEMEX’s directors and officers, as well as some of the experts named in this Form 20-F, reside outside the United States. Substantially all of our assets and those of most of our directors, officers and experts are located outside the United States. As a result, you may not be able to effect service of process on our directors or officers or those experts within the United States.

Considerations Related to Mexico

The current global financial crisis has led to lower oil prices and a lack of available credit; if the crisis continues or worsens, it could adversely affect our results of operations, financial condition and cash flows.

The current global financial crisis has had significant consequences worldwide, such as a global economic recession, exchange rate volatility, a lack of available credit, higher interest rates and a worldwide decrease in the demand for crude oil, natural gas and petrochemical products, which has led to lower oil and gas product prices. In Mexico, the consequences of this crisis have led to a 6.5% contraction in gross domestic product (GDP) during 2009 as compared to 2008 and a Mexican public sector deficit that has grown, in real terms, from 0.1% of Mexico’s GDP during 2008 to an estimated 2.3% of Mexico’s GDP during 2009. Any of these factors may adversely affect our results of operations, financial condition and cash flows, and may impact our ability both to access the financial markets and to maintain our budgeted level of capital expenditures.

Economic conditions and government policies in Mexico may have a material impact on PEMEX’s operations.

Further deterioration in Mexico’s economic condition, social instability, political unrest or other adverse social developments in Mexico could adversely affect our business and financial condition. Those events could also lead to increased volatility in the foreign exchange and financial markets, thereby affecting our ability to obtain and service foreign debt. Additionally, the Mexican Government may cut spending in the future. These cuts could adversely affect our business, financial condition and prospects. In addition to the current financial crisis, Mexico has experienced several past periods of slow or negative economic growth, high inflation, high interest rates, currency devaluation and other economic problems. These problems may worsen or reemerge, as applicable, in the future, and could adversely affect our business and our ability to service our debt.

Changes in exchange rates or in Mexico’s exchange control laws may hamper the ability of PEMEX to service its foreign currency debt.

The Mexican Government does not currently restrict the ability of Mexican companies or individuals to convert pesos into U.S. dollars or other currencies, and Mexico has not had a fixed exchange rate control policy since 1982. However, in the future, the Mexican Government could impose a restrictive exchange control policy, as it has done in the past. We cannot provide assurances that the Mexican Government will maintain its current

11

policies with regard to the peso or that the peso’s value will not fluctuate significantly in the future. The peso has been subject to significant devaluations against the U.S. dollar in the past and may be subject to significant fluctuations in the future. Mexican Government policies affecting the value of the peso could prevent us from paying our foreign currency obligations.

Most of our debt is denominated in U.S. dollars. In the future, we may incur additional indebtedness denominated in U.S. dollars or other currencies. Declines in the value of the peso relative to the U.S. dollar or other currencies may increase our interest costs in pesos and result in foreign exchange losses.

For information on historical peso/U.S. dollar exchange rates, see “Item 3—Key Information—Exchange Rates.”

Political conditions in Mexico could materially and adversely affect Mexican economic policy and, in turn, PEMEX’s operations.

Political events in Mexico may significantly affect Mexican economic policy and, consequently, our operations. On December 1, 2006, Felipe de Jesús Calderón Hinojosa, a member of the Partido Acción Nacional (National Action Party, or PAN), formally assumed office for a six-year term as the President of Mexico. Currently, no political party holds a simple majority in either house of the Mexican Congress.

Mexico has experienced a period of increasing criminal violence and such activities could affect PEMEX’s operations.

Recently, Mexico has experienced a period of increasing criminal violence, primarily due to the activities of drug cartels and related organized crime. In response, the Mexican Government has implemented various security measures and has strengthened its military and police forces. Despite these efforts, drug-related crime continues to exist in Mexico. These activities, their possible escalation and the violence associated with them, in an extreme case, may have a negative impact on our financial condition and results of operations.

Item 4. Information on the Company

HISTORY AND DEVELOPMENT

We are the largest company in Mexico, and according to the November 30, 2009 issue of Petroleum Intelligence Weekly, we were the third largest crude oil producer and the eleventh largest oil and gas company in the world based on data from the year 2008. In 1938, President Lázaro Cárdenas del Río nationalized the foreign-owned oil companies which were then operating in Mexico, and the Mexican Congress established Petróleos Mexicanos by a decree effective on July 20, 1938. Since 1938, Mexican federal laws and regulations have entrusted Petróleos Mexicanos with the central planning and management of Mexico’s petroleum industry. On July 17, 1992, the Mexican Congress created the subsidiary entities out of operations that had previously been directly managed by Petróleos Mexicanos. Petróleos Mexicanos and its four subsidiary entities, Pemex-Exploration and Production, Pemex-Refining, Pemex-Gas and Basic Petrochemicals and Pemex-Petrochemicals, are decentralized public entities of the Mexican Government, and each is a legal entity empowered to own property and carry on business in its own name.

PEMEX’s executive offices are located at Avenida Marina Nacional No. 329, Colonia Huasteca, México, D.F. 11311, México. PEMEX’s telephone number is (52-55) 1944-2500.

The activities of Petróleos Mexicanos and its subsidiary entities are regulated primarily by:

• the Ley Reglamentaria del Artículo 27 Constitucional en el Ramo del Petróleo (Regulatory Law to Article 27 of the Political Constitution of the United Mexican States Concerning Petroleum Affairs, which we also refer to as the Regulatory Law); and

• the Ley de Petróleos Mexicanos (Petróleos Mexicanos Law).

The Regulatory Law and the Petróleos Mexicanos Law grant Petróleos Mexicanos and certain of the subsidiary entities the exclusive right to:

• explore, exploit, refine, transport, store, distribute and sell (first-hand) crude oil;

• explore, exploit, produce and sell (first-hand) natural gas and transport and store natural gas, to the extent the transportation and storage activities are inextricably linked with such exploitation and production; and

• produce, store, transport, distribute and sell (first-hand) the derivatives of petroleum (including petroleum products) and natural gas used as basic industrial raw materials that constitute basic petrochemicals, which include ethane, propane, butanes, pentanes, hexanes, heptanes, naphthas, carbon black feedstocks and methane, but, in the case of methane, only if obtained from hydrocarbons used as basic raw materials by the petrochemical industry and obtained from deposits located in Mexico.

The operating activities of Petróleos Mexicanos are allocated among the four subsidiary entities, each of which has the characteristics of a subsidiary of Petróleos Mexicanos. The principal business lines of the subsidiary entities are as follows:

• Pemex-Exploration and Production explores for and exploits crude oil and natural gas and transports, stores and markets these hydrocarbons;

• Pemex-Refining refines petroleum products and derivatives that may be used as basic industrial raw materials and stores, transports, distributes and markets these products and derivatives;

• Pemex-Gas and Basic Petrochemicals processes natural gas, natural gas liquids and derivatives that may be used as basic industrial raw materials and stores, transports, distributes and markets these products and derivatives and produces, stores, transports, distributes and markets basic petrochemicals; and

13

• Pemex-Petrochemicals engages in industrial petrochemical processes and stores, distributes and markets petrochemicals other than basic petrochemicals.

Under the Petróleos Mexicanos Law, which replaced the Ley Orgánica de Petróleos Mexicanos y Organismos Subsidiarios (Organic Law of Petróleos Mexicanos and the Subsidiary Entities), the subsidiary entities will continue to conduct business in accordance with their mandates under existing law until the President of Mexico issues the appropriate reorganization decrees, based on a proposal by the Board of Directors of Petróleos Mexicanos.

In 1995, the Mexican Congress amended the Regulatory Law to allow private and social sector companies, which include labor-controlled organizations and industries, to participate, with the Mexican Government’s approval, in the storage, distribution and transportation of natural gas. Pursuant to the Regulatory Law, as amended, these types of companies may construct, own and operate pipelines, installations and equipment. Since 1997, the Mexican Government has required that we divest our existing natural gas distribution assets but has allowed us to retain exclusive authority over the exploration, exploitation, production and first-hand sale of natural gas, as well as the transportation and storage inextricably linked with this type of exploitation and production. See “Item 4—Information on the Company—Business Overview—Gas and Basic Petrochemicals—Private Sector Participation in Natural Gas Distribution.”

The Regulatory Law and the Petróleos Mexicanos Law have allowed us to co-generate electric energy and to enter into agreements with the Comisión Federal de Electricidad (Federal Electricity Commission) and Luz y Fuerza del Centro (Central Light and Power) to sell our production excess to these entities. On October 11, 2009, President Calderón issued a decree, in the Diario Oficial de la Federación (Official Gazette of the Federation), mandating the dissolution and liquidation of Central Light and Power. The funds and the public investment projects required to carry out these co-generation works and allow the acquisition of any additional production by such entities have been required to be (and in the case of the Federal Electricity Commission, still must be) included in the annual Presupuesto de Egresos de la Federación (Federal Expenditures Budget), which is subject to discussion by and approval of the Chamber of Deputies.

On October 28, 2008, the Mexican Congress approved ten bills, six of which amended the following laws:

• the Regulatory Law;

• the Ley Orgánica de la Administración Pública Federal (Federal Public Administration Organic Law);

• the Ley de la Comisión Reguladora de Energía (Energy Regulatory Commission Law);

• the Ley Federal de las Entidades Paraestatales (Federal Law of Decentralized Public Entities);

• the Ley de Obras Públicas y Servicios Relacionados con las Mismas (Law of Public Works and Related Services); and

• the Ley de Adquisiciones, Arrendamientos y Servicios del Sector Público (Law of Acquisitions, Leasing and Services of the Public Sector).

The other four bills enacted the following new laws:

• the Petróleos Mexicanos Law;

• the Ley de la Comisión Nacional de Hidrocarburos (National Hydrocarbons Commission Law);

• the Ley para el Aprovechamiento de Energías Renovables y el Financiamiento de la Transición Energética (Law of Use of Renewable Energy and Financing of the Energy Transition); and

• the Ley para el Aprovechamiento Sustentable de la Energía (Sustainable Use of Energy Law).

These bills became effective on November 29, 2008. None of them included any amendment to the Political Constitution of the United Mexican States.

14

In addition, the fiscal regime applicable to PEMEX was amended, effective January 1, 2009, to apply a differentiated fiscal regime that considers the complexities of our crude oil and natural gas fields. See “—Taxes and Duties—Fiscal Regime for PEMEX” in this Item 4.

PEMEX expects to benefit in several ways from the reforms adopted by these bills. In particular, we expect to improve, among other things, our decision-making processes and our execution capabilities through the adoption of corporate governance practices in line with international standards, the creation of seven executive committees to support the Board of Directors of Petróleos Mexicanos, the appointment of new professional members to the Boards of Directors of Petróleos Mexicanos and each of the subsidiary entities (see “Item 6—Directors, Senior Management and Employees”), the implementation of the differentiated fiscal regime that considers field complexities and the ability to issue bonos ciudadanos (Citizen Bonds) linked to our performance.

We are now permitted to have a more flexible contracting structure for our core production activities. In order to strengthen our ability to execute contracts, we are authorized to offer cash compensation to contractors that provide us with benefits from new technologies, faster execution or greater profits, subject to the requirement that payment obligations in respect of construction and services contracts always be made in cash and that in no case ownership rights over hydrocarbons be granted. We describe the main changes implemented by these laws in this report.

On October 21, 2008, the Mexican Congress approved a bill to modify the Federal Law of Budget and Fiscal Accountability, which became effective on November 14, 2008. Under these amendments:

• As of January 30, 2009, our Proyectos de Infraestructura Productiva de Largo Plazo (long-term productive infrastructure projects, which we refer to as PIDIREGAS) related debt was included in our balance sheet prepared under Mexican Governmental Accounting Standards and is now recognized as public sector debt. For Mexican FRS purposes, all of our PIDIREGAS-related financing and assets were already included in our consolidated balance sheet and, therefore, these amendments did not have a material effect on our consolidated balance sheet or income statement for any period.

• During the second half of 2009, Petróleos Mexicanos assumed, as primary obligor, all payment obligations under PIDIREGAS financing entered into by the Master Trust and Fideicomiso F/163, our principal PIDIREGAS financing vehicles. The legal procedures relating to this assumption were carried out in the second half of 2009.

On September 4, 2009, the Reglamento de la Ley de Petróleos Mexicanos (Regulations to the Petróleos Mexicanos Law) were published in the Official Gazette of the Federation. The Regulations to the Petróleos Mexicanos Law are a set of rules that regulate the application of the Petróleos Mexicanos Law in respect of, among other things: (i) the operation of the Board of Directors and committees of Petróleos Mexicanos; (ii) the authority of and the process for replacing the members of the Board of Directors and the Director General of Petróleos Mexicanos; (iii) Petróleos Mexicanos’ business planning and budgeting process, including provisions relating to acquisitions and financing programs; (iv) the approval of investment programs and specific investment projects; (v) the procurement of contracts by Petróleos Mexicanos (including contracts related to its core production activities); and (vi) the control, monitoring and performance evaluation of Petróleos Mexicanos. The Regulations to the Petróleos Mexicanos Law became effective as of September 5, 2009.

On September 4, 2009, the Board of Directors of Petróleos Mexicanos approved the Estatuto Orgánico de Petróleos Mexicanos (Organic Statute of Petróleos Mexicanos), which was published in the Official Gazette of the Federation on September 24, 2009, and became effective as of September 25, 2009.

On September 23, 2009, the new Reglamento de la Ley Reglamentaria del Artículo 27 Constitucional en el Ramo del Petróleo (Regulations to the Regulatory Law to Article 27 of the Political Constitution of the United Mexican States Concerning Petroleum Affairs) became effective. These new regulations relate to the oversight of Petróleos Mexicanos and its subsidiary entities, as well as their relations with the Mexican Government.

15

On December 18, 2009, the Disposiciones administrativas en materia de adquisiciones, arrendamientos, obras y servicios de las actividades sustantivas de carácter productivo de Petróleos Mexicanos y Organismos Subsidiarios (Administrative Guidelines for Acquisitions, Leasing, Works and Services of the Core Activities of Petróleos Mexicanos and Subsidiary Entities) were issued by the Board of Directors of Petróleos Mexicanos in accordance with the Petróleos Mexicanos Law. These guidelines were published on the Official Gazette of the Federation on January 6, 2010, and became effective on January 7, 2010. These guidelines regulate contracting procedures and the preparation, assignment and execution of contracts in connection with these activities. On March 10, 2010, modifications to these guidelines were also published to clarify the scope of these guidelines, in accordance with the Regulatory Law.

We have budgeted a total of Ps. 229.9 billion in nominal terms for capital expenditures in 2010. We expect to direct Ps. 186.5 billion (or 81.1% of total capital expenditures) to exploration and production programs in 2010.

Our main objectives for upstream investment are to maximize the long-term economic value, and increase as well as improve the quality of Mexico’s oil and gas reserves, enhance Pemex-Exploration and Production’s reserves recovery ratio, improve the reliability of its production and transportation infrastructure for crude oil and natural gas operations and continue to emphasize industrial safety and environmental compliance. The 2010 budget objectives include strengthening Pemex-Exploration and Production’s Strategic Gas Program to increase the supply of natural gas for the domestic market in the medium to long term.

Our downstream investment program seeks to improve the quality of our product selection and the reliability of our logistics and distribution services, to achieve a level of efficiency similar to that of our international competitors and to continue to emphasize industrial safety and environmental compliance. In addition, on August 12, 2009, with the required donation of land for the project by the government of Hidalgo having been completed, we announced the construction of a new refinery in Tula in the state of Hidalgo. We expect to invest approximately Ps. 137.0 billion in the new refinery, which is expected to have a Maya crude oil processing capacity of 250 thousand barrels per day and to produce approximately 142 thousand barrels per day of gasoline, 130 thousand barrels per day of diesel and 12 thousand barrels per day of jet fuel. We are also planning to renovate and upgrade our refinery in Salamanca, in the state of Guanajuato.

BUSINESS OVERVIEW

Overview by Business Segment

Exploration and Production

Pemex-Exploration and Production’s primary objectives for 2010 include: (1) sustaining current crude oil production levels in order to satisfy domestic demand and have surpluses available for export; (2) increasing natural gas production levels in order to reach a growth rate that satisfies domestic demand and decreases our dependence on natural gas imports; (3) continuing to increase the replacement rate of proved and total reserves; (4) maintaining discovery and development costs similar to those of our international competitors; and (5) improving performance in terms of industrial security and environmental protection, as well as continuing to build relationships with the communities in which we operate. Our downstream investment program seeks to meet these objectives by: maximizing the value of produced reserves; improving the quality of our product selection; and improving the reliability of our logistics and distribution services to achieve an optimal level of efficiency, while continuing to emphasize industrial safety and environmental compliance.

Pemex-Exploration and Production explores for and produces crude oil and natural gas, primarily in the northeastern and southeastern regions of Mexico and offshore in the Gulf of Mexico. In nominal peso terms, our capital investment in exploration and production activities increased by 32.6% in 2009, and we continued to finance an array of programs to expand production capacity and efficiency. As a result of our investments in previous years, our total hydrocarbon production reached a level of approximately 3,776 thousand barrels of oil equivalent per day in 2009. Pemex-Exploration and Production’s crude oil production decreased by 6.8% from 2008 to 2009, averaging 2,601.5 thousand barrels per day in 2009. This decrease was largely due to the decline of the Cantarell complex. Pemex-Exploration and Production’s natural gas production (excluding natural gas liquids) increased by 1.6% from 2008 to 2009, averaging 7,030.7 million cubic feet per day in 2009. This increase in natural gas production was a result of greater volumes from the Burgos, Ku-Maloob-Zaap, Delta del Grijalva, Costero, Crudo Ligero Marino and Ixtal-Manik projects. Exploration drilling activity increased by 15.4% from 2008 to 2009, from 65 exploratory wells completed in 2008 to 75 exploratory wells completed in 2009. Development drilling activity increased by 61.9% from 2008 to 2009, from 664 development wells completed in 2008 to 1,075 development wells completed in 2009. In 2009, we completed the drilling of 1,150 wells in total. Our drilling activity in 2009 was focused on increasing the production of non-associated gas in the Burgos and Macuspana regions and of heavy crude oil in the Ku-Maloob-Zaap project.

Our well-drilling activities during 2009 led to significant offshore discoveries of heavy and extra-light crude oil fields, specifically in the Southeastern basins, the Marine region and the part of the Northern region that is located within the Veracruz basin. Our current challenge with respect to these discoveries is their immediate development in order to maintain current production levels.

Pemex-Exploration and Production’s production goals for 2010 include maintaining its crude oil production at approximately 2.51 million barrels per day and maintaining its natural gas production at approximately 6.48 billion cubic feet per day, in order to better satisfy domestic demand for natural gas, and thus lower the rate of increase of imports of natural gas and natural gas derivatives.

Refining

Pemex-Refining converts crude oil into gasoline, jet fuel, diesel, fuel oil, asphalts and lubricants. It also distributes and markets most of these products throughout Mexico, where it experiences significant demand for its refined products. Pemex-Refining’s atmospheric distillation refining capacity remained constant at approximately 1,540 thousand barrels per day during 2009. In 2009, Pemex-Refining produced 1,343 thousand barrels per day of refined products as compared to 1,307 thousand barrels per day of refined products in 2008. This increase in refined products production was primarily due to greater crude oil processing as well as increased utilization of plants performing greater value-adding processing activities.

21

Gas and Basic Petrochemicals

Pemex-Gas and Basic Petrochemicals processes wet natural gas in order to obtain dry natural gas, LPG and other natural gas liquids. Additionally, it transports, distributes and sells natural gas and LPG throughout Mexico and produces and sells several basic petrochemical feedstocks, which are used by Pemex-Refining or Pemex-Petrochemicals. In 2009, Pemex-Gas and Basic Petrochemicals’ total sour natural gas processing capacity remained constant at 4,503 million cubic feet per day. Pemex-Gas and Basic Petrochemicals processed 3,381 million cubic feet per day of sour natural gas in 2009, a 6.1% increase from the 3,188 million cubic feet per day of sour natural gas processed in 2008. It produced 378 thousand barrels per day of natural gas liquids in 2009, a 0.5% increase from the 376 thousand barrels per day of natural gas liquids production in 2008. It also produced 3,572 million cubic feet of dry gas per day in 2009, 3.2% more than the 3,461 million cubic feet of dry gas per day produced in 2008.

Petrochemicals

Pemex-Petrochemicals manufactures different petrochemical products, including: (1) methane derivatives, such as ammonia and methanol; (2) ethane derivatives, such as ethylene, polyethylene, vinyl chloride monomer and ethylene oxide; (3) aromatics and their derivatives, such as styrene, toluene, paraxylene, benzene and xylene; (4) propylene and its derivatives, such as acrylonitrile; and (5) oxygen, nitrogen and other products. Pemex-Petrochemicals’ total annual production (excluding ethane and butane gases) decreased by 3.2% in 2009, from 7,841 thousand tons in 2008 to 7,587 thousand tons in 2009, mainly due to decreased production of certain products during 2009 (including ammonia, carbonic anhydride, ethylene oxide and glycols, gasoline blend and paraxylene) due to lower production of ethane and methane derivatives, as a result of the integration of the ethylene oxide project at the Morelos petrochemical complex and scheduled maintenance at the Cosoleacaque petrochemical complex. In addition, production of aromatics decreased, due to the shutdown of the paraxylene plant during the last quarter of 2008, because of market conditions, modifications made in the gasoline blend production program, shutdowns for the annual maintenance program and preparations undertaken to ensure compliance with the imported naphtha program for 2010. In order to provide figures comparable to those from past years, we have not included in this total an additional 3,899 thousand tons of refined products that were produced in a plant at the Cangrejera petrochemical complex which was transferred during 2008 from Pemex-Refining to Pemex-Petrochemicals.

International Trading

In 2009, our crude oil exports decreased by 12.9%, from 1,403.4 thousand barrels per day in 2008 to 1,222.1 thousand barrels per day in 2009. Natural gas imports decreased by 5.6% in 2009, from 447.1 million cubic feet per day in 2008 to 422.0 million cubic feet per day in 2009. In 2009, exports of petrochemical products by volume increased by 44.4%, from 539.6 thousand metric tons in 2008 to 779.4 thousand metric tons in 2009, while imports of petrochemical products by volume increased by 29.2%, from 439.8 thousand metric tons in 2008 to 568.3 thousand metric tons in 2009. In 2009, exports of refined products by volume increased by 33.0%, from 184.1 thousand barrels per day in 2008 to 244.8 thousand barrels per day in 2009, while imports of refined products by volume decreased by 7.6%, from 548.2 thousand barrels per day in 2008 to 506.4 thousand barrels per day in 2009.

We are a major supplier of crude oil to the United States. P.M.I. Comercio Internacional, S.A. de C.V. (which we refer to as PMI), P.M.I. Trading, Ltd. and their affiliates (which, together with PMI, we collectively refer to as the PMI Group) provide us and a number of independent customers with international trading, distribution and related services. The PMI Group sells, buys and transports crude oil, refined products and petrochemicals in world markets. The PMI Group also provides us with related risk management, insurance, transportation and storage services. The PMI Group has offices in Mexico City, Houston and Madrid. Our trading volume of sales and imports totaled U.S. $44,595.4 million in 2009, including U.S. $25,605.4 million in crude oil sales.

Exploration and Production

Exploration and Drilling

We seek to identify new oil reservoirs through our exploration program in order to increase the future replacement rate of proved reserves. From 1990 through 2009, we completed 7,754 exploration and development wells. During 2009, our average success rate for exploratory wells was 36% and our average success rate for development wells was 94%. From 2005 to 2009, we discovered 20 new crude oil fields and 49 new natural gas fields, bringing the total number of our crude oil and natural gas producing fields to 394 at the end of 2009.

The 2009 exploration program was comprised of exploration in both onshore and offshore regions, including the deep waters in the Gulf of Mexico, where we discovered new reservoirs that represent new drilling opportunities. These exploratory activities yielded 388.9 million barrels of oil equivalent of proved reserves in 2009. A total of 13 fields were discovered, seven of which contain non-associated gas and six of which contain crude oil. Within the currently producing fields, 14 reservoirs were discovered, seven of which contain non-associated gas and seven of which contain crude oil. In addition, two fields were delineated, a process that involves the drilling of several wells to determine the extent of the reserves found at each field. We also continued our main seismic data acquisition activities, in particular, those related to three-dimensional seismic data. We acquired 18,287 square kilometers of three-dimensional seismic data in 2009, of which 56% was in the deep waters of the Gulf of Mexico.

Extensions and Discoveries

During 2009, we discovered new sources of crude oil and natural gas reserves in 13 fields, ten of which were discovered onshore, six in the Northern region and four in the Southern region. We made three offshore field discoveries, two of which were in the Northeastern Marine region and the other of which was in the Southwestern Marine region. In addition, 14 reservoirs were discovered in currently producing fields. The new discoveries yielded a total of 388.9 million barrels of oil equivalent of proved reserves.

During 2009, in the Northeastern Marine region, the drilling of the Kayab-1DL well was completed and the Kayab field was delineated, which together led to the addition of 144.3 million barrels of oil equivalent of proved reserves. In the Southwestern Marine region, the drilling of the Xux-1 well and the delineation of the Ichalkil field through the drilling of the Ichalkil-1DL well led to the addition of 121.6 million barrels of oil equivalent of proved reserves. In the Northern region’s Burgos and Sabinas basins, the drilling of the Artimón-1, Barunda-1, Cucaña-1, Trapiche-1 and Cougar-1 wells, among others, as well as the discovery of new reservoirs in existing fields, led to the addition of 21.7 million barrels of oil equivalent of proved reserves. Finally, the drilling of the Bricol-1, Cupache-1, Madrefil-1 and Terra-1 wells and the discovery of new reservoirs in the Tupilco, Cinco Presidentes, Teotleco and Pijije fields in the Southern region led to the addition of 79.5 million barrels of oil equivalent of proved reserves.

With respect to the Aceite Terciario del Golfo project, Pemex-Exploration and Production has contracted with five firms for the installation of field laboratories in order to increase production volume and to develop new production mechanisms. This installation is expected to improve oil and gas recovery and lower our operating costs. The firms that will install these field laboratories are: Weatherford International Ltd., Halliburton Company, Baker Hughes Incorporated, Tecpetrol Internacional S.A. and Schlumberger Limited. This initiative has been undertaken in accordance with the principal strategy of Pemex-Exploration and Production relating to reorganization and technological improvements at the project, in order to increase the reservoir’s productivity. In addition, we have undertaken a 3D seismic acquisition program to better capture reservoir geometry and to increase the reliability of our geological models, thereby improving field development activities and secondary recovery methods at the project.

Reserves

Under the Political Constitution of the United Mexican States and the Regulatory Law, all oil and other hydrocarbon reserves within Mexico are owned by the Mexican nation and not by us. Under the Petróleos Mexicanos Law, Petróleos Mexicanos and the subsidiary entities, except for Pemex-Petrochemicals, have the exclusive right to extract, but not own, these reserves, and to sell the resulting production. The exploration and development activities of Petróleos Mexicanos and the subsidiary entities are limited to reserves located in Mexico.

Effective January 1, 2010, certain of the SEC’s rules have been revised in order to modernize the reporting requirements applicable to companies such as PEMEX in respect of oil and other hydrocarbon reserves. The most significant of these revisions include the following:

• Crude oil prices. Evaluation of the economic producibility of reserves and discounted cash flows must each now be based on a 12-month average crude oil price that is calculated by using the price on the first day of each month during the period, unless contractual arrangements designate a different price to be used.

• Proved undeveloped reserves. Reserves may now be classified as proved undeveloped reserves if: (1) there is a high degree of confidence that the relevant quantities of such reserves will be recovered; and (2) the related drilling is scheduled to begin within the next five years, unless the specific circumstances justify a longer time.

• Reserves estimation using new technologies. Reserves may now be estimated through the use of reliable advanced technologies in addition to those, such as flow tests and production history, previously recognized by the SEC.

25

• Reserves estimation personnel and process. Additional disclosure is now required regarding the qualifications of those who oversee a company’s reserves estimation process. A general discussion is also now required of the internal controls used to assure the objectivity of reserves estimates.

There has been no material change in Mexico’s proved reserves as a result of the application of these revised SEC rules.

Proved oil and natural gas reserves are those estimated quantities of crude oil, natural gas and natural gas liquids which geological and engineering data demonstrate with reasonable certainty to be economically producible—from a given date forward, from known reservoirs, and under existing economic conditions, operating methods and government regulations.

Proved reserves estimates as of December 31, 2009 were prepared by Pemex-Exploration and Production and were reviewed by the Independent Engineering Firms (as defined below), which audit our hydrocarbon reserves. However, pursuant to the Regulatory Law, the Comisión Nacional de Hidrocarburos (National Hydrocarbons Commission) is currently reviewing our hydrocarbon reserves estimates. Once this review has been completed, the Secretaría de Energía (Ministry of Energy) will disclose the hydrocarbon reserves of Mexico, as estimated by the National Hydrocarbons Commission. Differences may arise between our reserves estimates and those of the National Hydrocarbons Commission.

Pemex-Exploration and Production estimates Mexico’s reserves using standard geological and engineering methods generally accepted by the petroleum industry. The choice of method or combination of methods employed in the analysis of each reservoir is determined by:

• experience in the area;

• stage of development;

• quality and completeness of basic data; and

• production and pressure histories.

Reserves data set forth herein represent only estimates. Reserves valuation is a subjective process of estimating underground accumulations of crude oil and natural gas that cannot be measured in an exact manner. The accuracy of any reserves estimate depends on the quality of available data, engineering and geological interpretation and professional judgment. As a result, estimates of different engineers may vary. In addition, the results of drilling, testing and producing subsequent to the date of an estimate may lead to the revision of an estimate.

During 2009, we did not record any material increase in Mexico’s hydrocarbons reserves as a result of the use of new technologies.

In order to ensure the reliability of our reserves estimation efforts, since 1996 we have undertaken the internal certification of our estimates of Mexico’s reserves as follows. Initially, teams of geoscientists from Pemex-Exploration and Production’s exploration and exploitation business units (each of these units consisting of a series of projects) prepare the reserves estimates, using distinct estimation processes for valuations relating to new discoveries and developed fields, respectively. Subsequently, the regional reserves offices collect these reserves estimates from the units and request from the Gerencia de Reservas de Hidrocarburos y Proyectos de Explotación (the Hydrocarbons Reserves and Exploitation Projects Management Office), the central hydrocarbon reserves management body of Pemex-Exploration and Production, the review and certification of such valuations and the booking of the related reserves. This internal certification process is undertaken in accordance with internal guidelines for estimating and classifying proved reserves that are based on the SEC’s rules and definitions. The Hydrocarbons Reserves and Exploitation Projects Management Office, which additionally oversees and conducts an internal audit of the above process, consists entirely of professionals with geological, geophysical, petrophysical and reservoir engineering backgrounds. The engineers who participate in our reserves

estimation process are experienced in: reservoir numerical simulation; wells drilling and completion; Pressure, Volume and Temperature (PVT) analysis; NODAL^TM (an analytical tool used in forecasting the performance of the various elements comprising the production system) analysis; and design strategies in petroleum field development. Furthermore, all of our personnel have been previously certified by the Mexican Ministry of Education, most have earned master’s degrees in areas of study such as Petroleum Engineering, Geology and Geophysical Engineering and they possess an average of over ten years of professional experience.

In addition to the above internal review process, Pemex-Exploration and Production’s final reserves estimates are audited by independent engineering firms. Three independent engineering firms audited Pemex-Exploration and Production’s estimates of Mexico’s proved reserves as of December 31, 2009: Netherland, Sewell International, S. de R.L. de C.V. (Netherland Sewell); DeGolyer and MacNaughton (D&M); and Ryder Scott Company, L.P. (Ryder Scott, and, together with Netherland Sewell and D&M, the Independent Engineering Firms). The reserves estimates reviewed by the Independent Engineering Firms totaled 99.4% of Mexico’s reserves. The remaining 0.6% of reserves consisted of (a) reserves that are in the process of review but have not yet been certified and (b) reserves located in certain areas in which third parties provide drilling services to Pemex-Exploration and Production. Netherland Sewell reviewed the reserves in the Northeastern Marine region and Southern region, D&M reviewed the reserves in the Southwestern Marine region and Ryder Scott reviewed the reserves in the Northern region. In addition, Ryder Scott reviewed a portion of Mexico’s reserves located in areas in which third parties provide services to Pemex-Exploration and Production through the Financed Public Works Contracts program, as described under “—Information on the Company—Business Overview—Exploration and Production—Financed Public Works Contracts” in this Item 4. Under such agreements, the corresponding third party is responsible for assessing the volume of reserves, which is in turn certified by an engineering firm hired by such party. The audits conducted by the Independent Engineering Firms consisted primarily of: (1) analysis of historical static and dynamic reservoir data provided by Pemex-Exploration and Production; (2) construction or updating of the Independent Engineering Firms’ own static and dynamic reservoir characterization models of Mexican oil fields; (3) economic analysis of selected fields; and (4) review of Pemex-Exploration and Production’s production forecasts and reserves estimates.

Since reserves estimates are, by definition, only estimates, they cannot be reviewed for the purpose of verifying exactness. Instead, the Independent Engineering Firms conducted a detailed review of Pemex-Exploration and Production’s reserves estimates so that they could express an opinion as to whether, in the aggregate, the reserves estimates we furnished were reasonable and had been estimated and presented in conformity with generally accepted petroleum engineering and evaluation principles.

All questions that arose during the Independent Engineering Firms’ review process were resolved by Pemex-Exploration and Production to the satisfaction of the Independent Engineering Firms. The Independent Engineering Firms have concluded that our estimated total proved oil and natural gas reserve volumes set forth in this report are, in the aggregate, reasonable and have been prepared in accordance with Rule 4-10(a) of Regulation S-X of the SEC, as amended (which we refer to as Rule 4-10(a)), are consistent with international reserves reporting practice, and are in accordance with the revised oil and gas reserves disclosure provisions of the U.S. Financial Accounting Standards Board (FASB) Accounting Standards Codification (ASC) Topic 932-10-5 “Extractive Activities—Oil and Gas” (which we refer to as Topic 932).

Mexico’s total proved developed and undeveloped reserves of crude oil, condensates and liquefiable hydrocarbons recoverable from field processing plants decreased by 1.5% in 2009, from 11,865 million barrels at December 31, 2008 to 11,691 million barrels at December 31, 2009. Mexico’s proved developed reserves of crude oil, condensates and liquefiable hydrocarbons recoverable from processing plants decreased by 5.2% in 2009, from 8,618 million barrels at December 31, 2008 to 8,167 million barrels at December 31, 2009. These decreases were principally due to crude oil and condensates production during 2009, as well as a decline in crude oil reserves in the Akal field and the Paleocanal de Chicontepec, which were partially offset by the field development and reserves reclassification activities described below, as well as exploratory additions.

27

Mexico’s total proved developed and undeveloped dry gas reserves decreased by 5.8% in 2009, from 12,702 billion cubic feet at December 31, 2008 to 11,966 billion cubic feet at December 31, 2009. Mexico’s proved developed dry gas reserves decreased by 7.6% in 2009, from 8,206 billion cubic feet at December 31, 2008 to 7,586 billion cubic feet at December 31, 2009. Mexico’s proved undeveloped dry gas reserves decreased by 2.6% in 2009, from 4,496 billion cubic feet at December 31, 2008 to 4,380 billion cubic feet at December 31, 2009. These decreases were principally due to the volume of dry gas production during 2009, which was partially offset by exploratory additions.

Due to various field development activities performed during 2009, 750.9 million barrels of oil equivalent were reclassified from proved undeveloped, probable and possible reserves to proved developed reserves, at a cost of Ps. 150,135 million. The only fields containing material volumes of Mexico’s proved reserves that have remained undeveloped for five years or more are the Ayín and Alux fields, with this delay due to our having insufficient geological data relating to these fields. We have begun to address this lack of information by conducting additional studies aimed at reducing uncertainty in existing geological models. As a result, on February 18, 2010, the Ayín-Alux project commenced production with an initial oil flow rate of 4,700 barrels per day through the Alux-1A well. In addition, we completed the construction of 22 kilometers of 20” diameter pipeline connecting the Ayín field and the Alux-1A well to the host platform, which will allow us to better manage this project’s production.

The following three tables of crude oil and dry gas reserves set forth our estimates of Mexico’s proved reserves determined in accordance with Rule 4-10(a).

Pemex-Exploration and Production’s reserves replacement ratio (which we refer to as the RRR) has steadily improved over recent years. The RRR for a given period is calculated by dividing the sum of reserves additions due to discoveries, developments, delineations and revisions by that period’s total production. In 2009, the RRR was 77.1%, which was 5.3 percentage points higher than the 2008 RRR of 71.8%, and represented the highest rate attained since our adoption of Rule 4-10(a). This increase in our RRR was mainly due to decreased production in 2009, as compared to 2008.

Our goal is to achieve a 100% RRR by 2012, including by increasing Mexico’s proved reserves over the coming years. We aim to accomplish this primarily through development of the Ku-Maloob-Zaap, Crudo Ligero Marino and Aceite Terciario del Golfo projects, as well as through the performance of delineation activities. We have developed these objectives based on reserves estimates, which are subject to the uncertainty and risks associated with hydrocarbon exploration and production activities. Additionally, future decisions regarding authorized exploration and exploitation investment levels may lead to related changes.

Our reserves production ratio, which is presented in terms of years, is calculated by dividing the estimated remaining reserves at the end of the relevant year by the total production of hydrocarbons for that year. As of December 31, 2009, this ratio was equal to 10.2 years for proved reserves, which represents an increase of 3% as compared to the 2008 reserves production ratio of 9.9 years for proved reserves.

Sales Prices and Production Costs

The following table sets forth our average sales price per unit of oil and gas produced and our average production cost per unit of production, in the aggregate and for each field containing 15% or more of Mexico’s proved reserves.

In 2009, our average production cost of U.S. $4.85 per barrel of oil equivalent decreased by 21.3% as compared to U.S. $6.16 per barrel in 2008. This decrease resulted primarily from a 21% devaluation in the exchange rate of the Mexican peso against the U.S. dollar, as well as a 9.1% decrease in production expenses, from Ps. 99.5 billion in 2008 to Ps. 90.4 billion in 2009, mainly due to lower gas purchase costs. These factors were only partially offset by an increase in nitrogen acquisitions and a 5.0% reduction in total hydrocarbons production in 2009 as compared to 2008, from 1,451 million barrels of oil equivalent in 2008 to 1,378 million barrels of oil equivalent in 2009.

Pemex-Exploration and Production calculates and discloses our production costs pursuant to international practices. In accordance with ASC Topic 932, the production cost per barrel of oil equivalent is calculated by dividing total production expenses (in U.S. dollars) by total production of hydrocarbons (in barrels of oil equivalent) for the relevant period.

Our total production cost consists of all direct and indirect costs incurred to produce crude oil and gas, including costs associated with the operation and maintenance of wells and related equipment and facilities. In addition, it includes costs of labor to operate the wells and facilities, the costs of materials, supplies and fuel consumed, including gas used for gas lifting, nitrogen and other chemicals, repair and non-capitalized maintenance costs, and other costs, such as fees for general services, a labor fund for active personnel, corporate services and indirect overhead. However, it excludes non-cash expenses such as amortization of capitalized well expenses, the depreciation of fixed assets, expenses associated with the distribution and handling of hydrocarbons and other expenses that are related to exploration and drilling activities.

Crude Oil and Natural Gas Production

In 2009, we produced an average of 2,602 thousand barrels per day of crude oil, 6.8% less than our average daily production in 2008 of 2,792 thousand barrels per day of crude oil. The decrease in 2009 was due mainly to the decline of production in the Cantarell complex, which was only partially offset by an increase in crude oil production in the Ku-Maloob-Zaap complex. Shutdowns of wells in the offshore regions as a result of adverse weather conditions, maintenance and inventory accumulations also contributed to this decrease, as did the completion and workover of several wells in the Southwestern Marine and Southern regions. Accordingly, our production of heavy crude oil decreased by 245.7 thousand barrels per day, to 13.9% less than the average daily production in 2008; however, our light and extra-light crude oil production during 2009 increased by 55.6 thousand barrels per day, or a 5.4% increase as compared to 2008.

32

Crude oil can be classified by its sulfur content. “Sour” or heavy crude oil contains 3.4% or greater sulfur content by weight and “sweet” or light crude oil contains less than 1.0% sulfur content by weight. Most of our production is classified as sour or heavy crude oil.

Pemex-Exploration and Production produces four types of crude oil:

• Altamira, a heavy crude oil;

• Maya, a heavy crude oil;

• Isthmus, a light crude oil; and

• Olmeca, an extra-light crude oil.

Most of Pemex-Exploration and Production’s production consists of Isthmus and Maya crude oil. In 2009, 58.4% of Pemex-Exploration and Production’s total production of crude oil consisted of heavy crude oil and 41.6% consisted of light and extra-light crude oil. The Marine region yields mostly heavy crude oil (71.9% of this region’s production in 2009), although significant volumes of light crude oil are also produced there (28.1% of this region’s production in 2009). The Southern region yields mainly light and extra-light crude oil (together, 97.3% of this region’s production in 2009), and the Northern region yields both heavy crude oil (65.0% of this region’s production in 2009) and light and extra-light crude oil (35.0% of this region’s production in 2009).

The most productive crude oil and natural gas fields in the Gulf of Mexico are located in the Cantarell and Ku-Maloob-Zaap complexes in the Northeastern Marine region, and in the Chuc, Caan, Sinán and Ixtal fields in the Southwestern Marine region. In particular, the Cantarell business unit produced 684.8 thousand barrels per day of crude oil in 2009, or 26.3% of our total crude oil production for the year, and 1,455.3 million cubic feet per day of natural gas, or 20.7% of our total natural gas production for the year.

The following table sets forth our annual crude oil production rates by type of oil for the five years ended December 31, 2009.

Investments and Production by Project

We conduct exploration, production and development activities in fields throughout Mexico. Our eleven main projects are Cantarell, the Strategic Gas Program, Ku-Maloob-Zaap, Aceite Terciario del Golfo, Burgos, Antonio J. Bermúdez, Jujo-Tecominoacán, Delta del Grijalva, Integral Yaxché, Bellota-Chinchorro and Chuc. They are described below.

Cantarell Project. The Cantarell project is located on the continental shelf of the Gulf of Mexico. It consists of the Akal, Chac, Ixtoc, Kutz, Nohoch, Sihil and Takin fields, which extend over an area of 185.5 square kilometers. The Akal field is considered one of the last super giant oil fields in the world discovered in the past several decades. As of December 31, 2009, there were a total of 480 wells drilled in the Cantarell project, 163 of which were producing. During 2009, the Cantarell business unit, of which the Cantarell project is part, was the second most important producer of crude oil in Mexico, averaging 684.8 thousand barrels per day of crude oil. This was 34.1% less than 2008 production, which was 1,039.5 thousand barrels per day, as a result of the decline of these fields. Natural gas production from the Cantarell business unit during 2009 averaged 1,455.3 million cubic feet per day. This was 10.6% lower than the 2008 average natural gas production, which was 1,628.5 million cubic feet per day.

37

The Cantarell project averaged 646.5 thousand barrels per day of crude oil production during 2009. This was 35.9% less than production in 2008, which was 1,008.8 thousand barrels per day. Natural gas production from the Cantarell project during 2009 averaged 1,452.5 million cubic feet per day. This was 10.7% lower than the 2008 average natural gas production, which was 1,626.4 million cubic feet per day.

As of December 31, 2009, cumulative production of the Cantarell project was 13.3 billion barrels of crude oil and 6.4 trillion cubic feet of natural gas. As of December 31, 2009, proved hydrocarbon reserves of the Cantarell project totaled 2.4 billion barrels of crude oil and 1.4 trillion cubic feet of natural gas. As of December 31, 2009, total proved reserves were 2.7 billion barrels of oil equivalent, 2.4 billion of which were developed.

We note that the annual rate of decline in production of the Akal field, which is the most important field in the Cantarell project, decreased from 38% in the first half of 2008 to 15% in the second half of 2009. This decrease in the decline rate contributed to our maintaining the production levels described above.

In nominal peso terms, Pemex-Exploration and Production’s capital expenditure on developing reservoirs in the Marine region totaled Ps. 21,009 million in 2007, Ps. 29,073 million in 2008 and Ps. 41,002 million in 2009. For 2010, we have budgeted Ps. 38,041 million for capital expenditures for the Cantarell project. By the end of 2010, we expect our capital expenditures to total approximately U.S. $29.6 billion for this project.

On October 10, 1997, we awarded a build-own-operate contract for a nitrogen cryogenic plant at the Cantarell complex to a consortium formed by BOC Holdings, Linde, Marubeni, West Coast Energy and ICA Fluor Daniel. Under this contract, the consortium is responsible for the financing, design, construction and operation of the plant. The plant began operations in 2000 and cost approximately Ps. 10,131 million in nominal terms. Pursuant to the terms of the agreement, Pemex-Exploration and Production has the right to acquire the nitrogen plant in the case of a default by the consortium. Pemex-Exploration and Production has the obligation to acquire the nitrogen plant if it defaults under the contract. Under the terms of the contract, Pemex-Exploration and Production has committed to purchase 1.2 billion cubic feet per day of nitrogen from the consortium for a period of 15 years. Because less pressure will be necessary as the Cantarell fields decline, the volume of nitrogen needed for injection into these fields will decrease over time. We therefore plan to direct an increasing amount of this nitrogen instead to the Ku-Maloob-Zaap project.

During 2009, Pemex-Exploration and Production paid approximately U.S. $60 million under this contract for an approximate total volume of 14 billion cubic feet of nitrogen, which was injected into the Cantarell fields. In 2010, Pemex-Exploration and Production expects to pay approximately U.S. $63 million under this contract for an approximate total volume of 14 billion cubic feet of nitrogen to be injected into the fields.

Strategic Gas Program (SGP). In 2001, Pemex-Exploration and Production began a nine-year, U.S.$8,105 million Strategic Gas Program. Based on the expected acceleration of growth in the demand for natural gas in the medium- and long-term as compared to its projected supply, Pemex-Exploration and Production reviewed its energy policy. With the objective of addressing natural gas shortages, Pemex-Exploration and Production identified and selected a portfolio of investment options aimed at increasing gas production. Field development and production optimization represents 76% of SGP expenditures, with the goal of increasing the production of natural gas to 2,308 million cubic feet per day by 2015. Exploration activities, which include twelve different exploratory natural gas and integral gas projects, represent 12% of SGP expenditures, with the goal of increasing proved reserves. Development of newly discovered fields represents 12% of SGP expenditures. The Veracruz and Crudo Ligero Marino projects in the Northern and Southwestern Marine regions are the SGP’s most important projects.

• Veracruz Project. The Veracruz project is the second most important non-associated gas project in Mexico. It is located on the western margin of the Gulf of Mexico, in central Veracruz. During 2009, it produced an average of 0.8 billion cubic feet of natural gas per day. As of December 31, 2009,

38

cumulative production totaled 2.6 trillion cubic feet of natural gas. Proved hydrocarbon reserves totaled 0.9 trillion cubic feet of natural gas or 182.5 million barrels of oil equivalent. In addition, developed reserves totaled 0.9 trillion cubic feet of natural gas, or 172.9 million barrels of oil equivalent. Three of the most important fields in the Veracruz project are Lizamba, Papán and Cauchy.

• Lizamba. This field covers an area of 40 square kilometers. During 2009, it produced an average of 263.8 million cubic feet of natural gas per day. As of December 31, 2009, the drilling of 57 wells had been completed, and 42 of these wells were operating. Proved reserves were 144.1 billion cubic feet of natural gas or 27.6 million barrels of oil equivalent, all of which were developed.

• Papán. This field covers an area of 29.4 square kilometers. Gas production averaged 244.5 million cubic feet of natural gas per day in 2009. As of December 31, 2009, the drilling of 24 wells had been completed, and 22 of these wells were operating. As of December 31, 2009, proved reserves totaled 198.9 billion cubic feet of natural gas or 38.2 million barrels of oil equivalent, all of which were developed.

• Cauchy. This field, which was discovered in 2008, is one of the most important discoveries of non-associated gas in the Veracruz basin. The field covers an area of 18.0 square kilometers. As of December 31, 2009, 14 wells had been completed, of which only seven were operating due to the lack of gas transportation capacity. As of the date of this report, all wells are now operating. As of December 31, 2009, proved reserves totaled 250.3 billion cubic feet of natural gas or 48.1 million barrels of oil equivalent, of which 224.7 billion cubic feet of natural gas or 43.2 million barrels of oil equivalent were developed.

• Crudo Ligero Marino Project. This project is located on the continental shelf of the Gulf of Mexico off the coast of the states of Tabasco and Campeche, 76 kilometers northeast from the Dos Bocas Marine Terminal in Paraíso, Tabasco. The project is composed of the Bolontikú, Citam, Ichalkil, Kab, Kix, May, Men, Misón, Nak, Sinán, Yum, Tsimin and the newly discovered Xux fields, all in the Southwestern Marine region. As of December 31, 2009, the drilling of 70 wells had been completed, and 37 of these wells were producing. Approximately half of the fields in this project are not yet developed. During 2009, average daily production totaled 166.7 thousand barrels of crude oil and 471.0 million cubic feet of natural gas. As of December 31, 2009, cumulative production totaled 249.6 million barrels of crude oil and 644.6 billion cubic feet of natural gas. Proved hydrocarbon reserves totaled 352.0 million barrels of crude oil and 1.7 trillion cubic feet of natural gas. Total proved reserves were 696.0 million barrels of oil equivalent, of which 301.3 million barrels were developed.

In nominal peso terms, Pemex-Exploration and Production’s capital expenditures for the SGP were Ps. 20,211 million in 2007, Ps. 26,717 million in 2008 and Ps. 28,626 in 2009. For 2010, we expect capital expenditures to be Ps. 32,482 million, which would bring our total capital expenditures for the program to approximately U.S. $17.5 billion through December 31, 2010.

From 2005 to 2009, average production from the SGP was 1.7 billion cubic feet of natural gas per day. Since 2005, 121 exploratory wells have demonstrated offshore and onshore gas potential, resulting in a 40% exploratory success ratio. During 2009, one field was discovered in the Veracruz basin through the Cervelo 1A well, which added 7.2 billion cubic feet of natural gas to proved reserves. Development activities have focused mainly on the Costero project, specifically on the Costero field, where 34.2 million barrels of oil equivalent were added from the drilling of two wells during 2009. Similar development activities were performed in the Crudo Ligero Marino project, specifically at the May, Kab and Sinán fields, and in the Veracruz project, mainly in the Cauchy field.

Ku-Maloob-Zaap Project. The Ku-Maloob-Zaap project is one of the main producers of heavy crude oil and plays an important part in the production of the Maya crude oil mix. It is the most important project in Mexico in terms of total proved hydrocarbon reserves and crude oil production. It is composed of the Bacab, Lum, Ku, Maloob and Zaap fields, and extends over an area of 149.5 square kilometers. As of December 31, 2009, there

Maya crude oil accounted for 31% of domestic consumption in 2009. Due to its high sulfur content, Maya crude oil requires extra processing and has lower refining yields than most valuable sweet crudes, and thus requires extra investment by the purchaser to refine. Therefore, we receive a lower price for Maya crude oil than we do for sweeter crude oils that cost less to refine. As a consequence of this price difference, we have supported the export value of sour crude oil such as Maya crude oil in relation to other grades of crude oil by creating incentives for refiners to invest in high-conversion refineries capable of upgrading the relatively large proportion of residue produced from processing sour crude oil. We have done this by entering into long-term Maya crude oil supply agreements pursuant to which purchasers have agreed to undertake projects to expand the capacity of their respective refineries to upgrade residue from Maya crude oil, and we have provided, for a limited period, support mechanisms to protect refinery margins in certain adverse market conditions. See “—Business Overview—International Trading—Geographic Distribution of Export Sales” in this Item 4.

Gas Flaring

The flaring of produced gas, which consists of the burning off of surplus combustible vapors from a well, either as a means of disposal or as a safety measure to relieve well pressure, is considered to be one of the most significant sources of air emissions from offshore oil and gas installations. In 2009, gas flaring represented

44

14.7% of our total natural gas production, which is a decrease from 2008, when gas flaring represented 19.3% of total natural gas production. This decrease was due to a reduction in operational problems and to increased efficiency of platforms as a result of maintenance. Pemex-Exploration and Production’s goal is to reduce gas flaring to 3.5% of total natural gas production by the end of 2010.

Pipelines

The crude oil and natural gas pipeline network owned by Pemex-Exploration and Production connects crude oil and natural gas producing centers with refineries and petrochemical plants. At the end of 2009, this pipeline network consisted of approximately 37,758 kilometers of pipelines, of which 3,516 kilometers were located in the Marine region, 11,974 kilometers were located in the Southern region and 22,268 kilometers were located in the Northern region. For a description of products transported by the pipeline network, see “—Business Overview—Transportation and Distribution” in this Item 4.

Financed Public Works Contracts

Our Financed Public Works Contracts program, or FPWC, previously known as the Multiple Services Contracts program, was first announced in December 2001. The objective of the program is to provide a contractual framework that promotes an efficient execution of public works, in order to increase Mexico’s hydrocarbons production. The FPWC are public works contracts based on unit prices that aggregate a number of different services into a single contract. Under the FPWC framework, Pemex-Exploration and Production retains the rights and title to all hydrocarbons produced and works performed under each FPWC, because all work is performed on behalf of Pemex-Exploration and Production.

The invitation for bids for the first three rounds of FPWC bidding, corresponding to works and services necessary for non-associated natural gas production in nine blocks in the Burgos basin, occurred in July 2003, in the second half of 2004 and in August of 2006, respectively. The following table summarizes the results of those rounds.

During 2009, among other works performed under the FPWC program, 87 wells were drilled, which represents approximately 22% of all wells drilled in Burgos. Also in 2009, 104 wells were completed, consisting of 90 development wells and 14 exploratory wells. All but five of these completed wells were productive. In addition, 1,466 square kilometers of three-dimensional seismic information were acquired during 2009, which represents 52% of the total seismic information acquired for the Burgos project. The works carried out in 2009 represented an investment of approximately U.S. $290 million. By the end of 2009, natural gas production in the existing FPWC blocks reached 468 million cubic feet per day.

There is one pending legal proceeding related to the FPWC program. See “Item 8—Financial Information—Legal Proceedings––Civil Actions.”

These broad agreements of technological and scientific collaboration are strictly non-commercial, i.e., there is no transfer of resources among the parties.

Refining

Refining Processes and Capacity

Pemex-Refining’s production processes include the following:

• Atmospheric distillation. This process heats crude oil in a tube furnace at atmospheric pressure to distill refined products. The primary products produced are gasoline, kerosene, jet fuel, diesel, atmospheric gas oil and atmospheric residual crude oil.

• Vacuum distillation. This process heats crude oil or other feedstock in a vacuum distillation column, which is operated at low pressures. The objective of this process is to maximize production of heavy vacuum gas oil, which is produced by boiling crude oil.

• Cracking. This process uses either heat and pressure or a catalytic agent to increase gasoline yields from crude oil.

• Visbreaking. This is a thermal cracking process, which uses a horizontal-tube heater fired to a high temperature. Visbreaking reduces flasher bottom viscosity and produces some heavy gas oil.

• Reforming processes. These processes use heat and catalysts to transform smaller or unstable hydrocarbon molecules into larger, more useful refining or blending products. For example, Pemex-Refining uses reforming processes to convert low octane gasoline into higher octane stocks that are suitable for blending into finished gasoline and to convert naphthas into more volatile, higher octane products.

• Hydrotreatment or resid hydrocracking. This process uses a catalyst and hydrogen at high temperature and pressure to remove sulfur, nitrogen and some aromatic compounds. Hydrotreatment also processes some lighter liquid product off-take.

• Alkylation and isomerization. This polymerization process unites olefins and isoparaffins. Butylenes and isobutanes are combined with sulfuric acid or hydrofluoric acid to rearrange straight-chain hydrocarbon molecules into branched-chain products. Pentanes and hexanes, which are difficult to reform, are isomerized through the use of aluminum chloride and other precious-metal catalysts. Normal butane may be isomerized to provide a portion of the isobutane feed needed for the alkylation process. The process produces a high octane, low sensitivity blending agent for gasoline.

• Coking. This process is a severe method of thermal cracking used to upgrade heavy residuals into lighter products or distillates. Coking produces straight-run gasoline (coker naphtha) and various middle-distillate fractions used as catalytic feedstock, thus generating a concentrated solid material called coke of petroleum.

At the end of 2009, Pemex-Refining owned and operated six refineries: Cadereyta, Madero, Minatitlán, Salamanca, Salina Cruz and Tula. Our refineries are comprised of atmospheric and vacuum distillation units, where the bulk of crude oil input is processed. Secondary processing facilities include desulfurization units and facilities for catalytic cracking, reforming and hydrotreating. During 2009, our refineries processed 1,295 thousand barrels per day of crude oil (217 thousand barrels per day at Cadereyta, 152 thousand barrels per day at Madero, 167 thousand barrels per day at Minatitlán, 192 thousand barrels per day at Salamanca, 277 thousand barrels per day at Salina Cruz and 290 thousand barrels per day at Tula), which total consisted of 778 thousand barrels per day of Olmeca and Isthmus crude oil and 517 thousand barrels per day of Maya crude oil.

Since 1993, through our subsidiary company, P.M.I. Norteamérica, S.A. de C.V., we have participated in a limited partnership with Shell Oil Company in a refinery located in Deer Park, Texas, which has the capacity to process 340 thousand barrels per day of crude oil. Under the Deer Park Limited Partnership agreement, P.M.I. Norteamérica, S.A. de C.V. and Shell Oil Company each provide 50% of the refinery’s crude oil input and own 50% of the refinery’s output.

Production

Pemex-Refining produces a wide range of products derived from crude oil and natural gas, including LPG, gasoline, jet fuel, diesel, fuel oil, asphalts, lubricants and other refined products. Pemex-Refining produced 1,343 thousand barrels per day of refined products (including dry gas by-products of the refining process) in 2009, an increase of 2.7% from 2008 levels. This increase in refined products production was primarily due to greater crude oil processing, as well as increased utilization of plants performing greater value-adding activities.

Fuel oil, automotive gasoline and diesels represent the bulk of Pemex-Refining’s production. In 2009, fuel oil represented 24%, gasoline represented 35% and diesel fuel represented 25% of total refined products production. Jet fuel represented 4% and LPG represented 2% of total production of refined products in 2009. The remainder of Pemex-Refining’s production consisted of a variety of other refined products.

As a result of our strategy of investing in technology to improve the quality of our fuels, over the past several years Pemex-Refining has increased its production of unleaded gasoline (including Pemex Premium) as opposed to leaded gasoline (Nova Base, a leaded gasoline, is produced only as a base for other products). All of

49

our automotive gasoline production now consists of unleaded gasoline. In addition, we have introduced new environmentally sound products such as Ultra Low Sulfur gasoline and diesel. We also promote LPG as an environmentally sound substitute fuel for gasoline in motor vehicles.

Domestic Sales

We market a full range of refined products, including gasoline, jet fuel, diesel, fuel oil and petrochemicals. We are one of a few major producers of crude oil worldwide that experiences significant domestic demand for our refined products.

Over the five years ended December 31, 2009, the value of Pemex-Refining’s domestic sales of refined products and petrochemicals was as follows:

The largest consumers of fuels in Mexico are the Federal Electricity Commission and our subsidiary entities. The Federal Electricity Commission consumed approximately 82% of our fuel oil production during 2009, pursuant to a fuel oil supply contract entered into in November 1995 and amended effective January 1, 2005. Pursuant to this amendment, the minimum amount of fuel oil that we agreed to supply to the Federal Electricity Commission during 2009 was 71,940 barrels per day, in accordance with the supply capacity of Pemex-Refining and the reduced requirements of the Federal Electricity Commission under its official program of substitution of fuel oil with natural gas. The price per cubic meter of the fuel oil supplied to the Federal Electricity Commission is based on the three-month average spot price per cubic meter of Fuel Oil No. 6 (3% sulfur) at Houston, Texas, as quoted in Platt’s U.S. Marketscan and adjusted for quality and transportation cost differentials. In addition, the price of the fuel oil is discounted by a commercial margin on each cubic meter of fuel oil. In 2009, this volume discount amounted to approximately 0.7% of total fuel oil sales to the Federal Electricity Commission. The contract can be terminated by either party upon six months’ notice. The total amount paid to us by the Federal Electricity Commission under this contract in 2009 was Ps. 43,217 million, which represented 9.3% of our total revenues from domestic sales of refined products.

In 2009, our domestic sales of refined oil products decreased by Ps. 23,457 million, or 4.8% in value, as compared to 2008 levels. This decrease was primarily due to lower international prices of refined products in 2009 and a 2.9% decrease in the volume of domestic sales.

The volume of our domestic gasoline sales decreased by 0.03% in 2009, from 792.6 thousand barrels per day in 2008 to 792.4 thousand barrels per day in 2009. The volume of our domestic diesel sales decreased by 6.0%, from 382.0 thousand barrels per day in 2008 to 359.0 thousand barrels per day in 2009. The volume of our domestic sales of fuel oil decreased by 4.8%, from 219.6 thousand barrels per day in 2008 to 209.0 thousand barrels per day in 2009, primarily due to a decrease in the Federal Electricity Commission’s demand for fuel oil, which they are replacing with natural gas under the official program discussed above.

The volume of Pemex-Refining’s domestic sales of refined products for the five-year period ended December 31, 2009 was distributed as follows.

Since 1998, at the retail level, we have offered standard and premium grades of unleaded gasoline throughout the country. As of October 2006, all Pemex Premium gasoline has an ultra-low sulfur content of 0.003%. Since January 2007, diesel sold at the northern border of Mexico has a sulfur content of 0.0015%. Our efforts to build and enhance our brands have also progressed during the past five years. All of Mexico’s independent gasoline service stations now participate in our franchise program, which provides financial assistance to upgrade equipment and facilities, as well as technical assistance in the development of marketing and customer service programs. At the end of 2009, there were 8,803 retail service stations franchised by Pemex-Refining, of which 8,754 were privately owned and operated as franchises and 49 were owned by Pemex-Refining. This total number of retail service stations represented an increase of 5.4% from the 8,351 service stations as of December 31, 2008.

Pricing Decrees

In September 2007, the Mexican Government announced that it was suspending the periodic increases in retail prices of unleaded gasoline and diesel from October 2007 to December 2007. On December 21, 2007, the Mexican Government renewed the periodic increases in these prices. During 2008, these increases ranged from two to ten Mexican cents per liter per month for unleaded gasoline.

On January 7, 2009, President Calderón announced the Acuerdo Nacional en favor de la Economía Familiar y el Empleo (National Agreement in Favor of Family Economy and Employment), an agreement aimed at mitigating the effects on Mexico of the global economic crisis. The agreement suspended the periodic increases in the retail price of unleaded gasoline until December 18, 2009. From December 19, 2009 to May 8, 2010, the Mexican Government renewed these periodic price increases, which ranged from four to nine Mexican cents per liter per month.

Periodic increases in diesel prices ranged from two to eight Mexican cents per liter per month during the first seven months of 2008, and from 20 to 30 Mexican cents per liter per month from August 2008 to February 6, 2009. From February 7, 2009 to December 25, 2009, diesel prices were periodically increased by five Mexican cents per liter per month. From December 26, 2009 to May 8, 2010, the Mexican Government renewed these periodic price increases in increments of eight Mexican cents per liter per month. Despite these increases, diesel prices in Mexico have remained below most international diesel reference prices.

Since the early 1980s, the Mexican Government has also established a discount of 30% on the price at which we sell domestic gas oil to the State of Chihuahua during the months of January, February and December of each year.

On January 29, 2008, the Mexican Government established a discount of 10% on the price at which we sell fuel oil to the Federal Electricity Commission. This discount was effective from January 1, 2008 to March 31, 2008. From April 2008 to November 2008, the discount was 8%. Since December 2008, the price at which we sell fuel oil to the Federal Electricity Commission has been linked to international market prices in accordance with a pricing methodology established by the Mexican Government. This methodology is based on the price of fuel oil in the U.S. Gulf of Mexico coastal region, and is then adjusted for quality as well as expenses related to distribution.

In addition, during 2009, pursuant to the National Agreement in Favor of Family Economy and Employment, the international reference price we use in sales of fuel oil to the Federal Electricity Commission was changed from a three-month daily average to a one-month daily average in an effort to reduce the cost of electricity to end users. On January 8, 2009, and also under the National Agreement in Favor of Family Economy

52

and Employment, a resolution was issued establishing terms and conditions applicable to the transportation, storage, distribution and first-hand sale of fuel oil and basic petrochemicals, as well as related pricing methodologies.

The Mexican Government could modify these price controls or impose additional price controls in the future.

Investments

Over the past several years, Pemex-Refining has focused its investment program on enhancing the quality of the gasoline and diesel it produces to meet new environmental standards in Mexico, improving its ability to process heavy crudes in order to optimize the crude oil blend in its refineries and increasing the production of unleaded gasoline and diesel to supply growing demand at low cost, as opposed to increasing its overall crude oil processing capacity. This focus is primarily the result of the abundance of heavy crudes in Mexico. In addition, due to the reduced availability of heavy crudes in the export markets, the lower cost of raw materials in Mexico leads to higher profit margins on the heavy crudes we do export. In the medium term, Pemex-Refining will continue to import unleaded gasoline to satisfy domestic demand. During 2009, Pemex-Refining imported approximately 330 thousand barrels per day of unleaded gasoline, which represented almost 41.6% of total domestic demand for unleaded gasoline in that year. In 2009, Pemex-Refining invested Ps. 18,526 million in capital expenditures, 6.6% more than its Ps. 17,380 million of capital expenditures in 2008. Of this total investment, Pemex-Refining allocated Ps. 5,159 million to the Minatitlán project, Ps. 1,736 million to its investments to expand and upgrade refineries and related installations, Ps. 1,636 million to environmental and industrial safety projects, Ps. 7,174 million to rehabilitation projects, Ps. 2,782 million to other projects and acquisitions and Ps. 39 million in preinvestment studies related to the new refinery in Tula, Hidalgo.

Clean Fuels Project. This project will be developed in our six refineries, with a first phase to include the installation of eight ultra-low sulfur gasoline (ULSG) post-treatment units, the capacities of which are set forth below by refinery. Construction on these units was planned to begin in 2009 and to be completed by 2013. However, delays in the related bidding process have postponed the beginning of construction to the end of 2010. The second phase of this project, which involves the construction of five new ultra-low sulfur diesel facilities and the reconfiguration of 17 existing units, is currently in the engineering development stage and is expected to be completed by 2014. This project has two components: construction at the Cadereyta refinery is planned to begin in late 2010, while construction at the country’s remaining refineries is expected to begin in 2011. Until construction is completed, we will import ultra-low sulfur fuels in order to meet local demand.

New Refinery at Tula. On August 12, 2009, with the required donation of land for the project by the government of Hidalgo having been completed, we announced the construction of a new refinery in Tula in the state of Hidalgo. The new refinery is expected to have a Maya crude oil processing capacity of 250 thousand barrels per day, and to produce approximately 142 thousand barrels per day of gasoline, 130 thousand barrels per day of diesel and 12 thousand barrels per day of jet fuel. All distilled products of the refinery will meet ultra-low sulfur content specifications, and no fuel oil will be produced. As of December 2009, the total estimated cost of the refinery was Ps. 137.0 billion.

Reconfiguration of the Salamanca Refinery. On April 14, 2009, the Director General of Petróleos Mexicanos also announced plans for the reconfiguration of the “Ingeniero Antonio M. Amor” refinery in Salamanca, with a focus on residual conversion into high-value distillates (without a need for increased crude oil processing), as well as upgrading of the lubricants train to produce group II lubricants. This reconfiguration, together with the construction of the new refinery in Tula, is expected to increase the capacity and profitability of the entire national refining system. In 2009, the selection of technologies for residual conversion was performed for all except the lubricants portion of the project. This project is currently in preparation for the engineering phase.

Samsung Ingeniería Minatitlán, S.A. de C.V. and Samsung Engineering, Co. Ltd.	February 2005		154.1

The execution strategy of the Minatitlán project has been to manage it in six packages. Package No. 1 (consisting of site preparation activities) was completed in October 2005. Due to delays in the construction process during 2009, Package No. 2 (relating to utilities) was completed in early 2010 and is expected to begin operations in July 2010. We now expect the four remaining Packages of the project to start operations as follows: Packages No. 3 (consisting of an atmospheric and vacuum unit to process 100% Maya crude oil, a catalytic cracking unit and a diesel hydrotreatment unit) and No. 4 (consisting of a gas oil hydrotreatment plant, a hydrogen unit and a sulfur recovery unit) in December 2010; Package No. 5 (consisting of a delayed coking unit, an amine regenerator plant and a coker naphtha hydrotreatment unit) in March 2011; and Package No. 6 (consisting of two alkylation plants—U-18000 and U-19000) in January 2011. During 2009, we spent an estimated Ps. 5,159 million on the Minatitlán project.

Tuxpan Pipeline. This project is intended to help meet the increasing demand for refined products in the metropolitan area of the Mexico Valley. We are investing Ps. 3,366 million in the project, which includes the construction of a pipeline measuring 18 inches in diameter and 109 kilometers in length, five storage tanks located at the Tuxpan Maritime Terminal with a capacity of 100,000 barrels each and a research study to determine the best option for the discharge of refined products from tankers and pipelines to these storage tanks. ARB Arendal, S. de R.L. de C.V. began construction of the pipeline in June 2009: the pipeline is scheduled to be completed in December 2010. Tradeco Infraestructura, Tradeco Industrial, ITECSA and Grupo OLRAM were, in association, awarded the contract for construction of the storage tanks, which they began in December 2009 and

54

are scheduled to complete in December 2010. Finally, the Federal Electricity Commission conducted the research study, the results of which were delivered to us in April 2010. The Federal Electricity Commission concluded that we do not need to invest in additional discharge systems, due to our having a sufficient amount of monobuoys already in operation.

2010 Refining Investment Budget. For 2010, Pemex-Refining has budgeted Ps. 32,000 million of expenditures for investment projects. Pemex-Refining will invest 31% of this amount to expand and upgrade refineries and related installations, 12% on the planning of the new refinery in Tula, 19% environmental and industrial safety projects, 30% rehabilitation projects and 8% other projects and acquisitions.

Gas and Basic Petrochemicals

Natural Gas and Condensates

Pemex-Exploration and Production’s average natural gas production increased by 1.6% in 2009, from 6,919 million cubic feet per day in 2008 to 7,031 million cubic feet per day in 2009, while the average wet natural gas processed by Pemex-Gas and Basic Petrochemicals increased by 4.6%, from 4,240 million cubic feet per day in 2008 to 4,436 million cubic feet per day in 2009. Natural gas production associated with crude oil production accounted for 63.7% of total natural gas production in 2009, with the remainder of natural gas production consisting of extraction from fields holding natural gas reserves. Although natural gas production is more geographically diverse than crude oil production, 174 fields (or 44.2% of the 394 producing fields) accounted for 36.3% of all natural gas production in 2009. Of total natural gas production, 41.2% originated in the Marine region, 22.7% in the Southern region and the remainder, 36.1%, originated in the Northern region.

All wet natural gas production is directed to Pemex-Gas and Basic Petrochemicals’ gas processing facilities. At the end of 2009, Pemex-Gas and Basic Petrochemicals owned 12 facilities.

Domestic consumption of dry gas totaled 5,296 million cubic feet per day in 2009, a 0.6% increase from the 2008 domestic consumption of 5,263 million cubic feet per day. The subsidiary entities consumed approximately 41.1% of the total domestic dry gas consumed in 2009, while the industrial-distributor sector consumed 18.9%, the electrical sector consumed 34.0%, the electrical autogeneration sector consumed 2.6% and the trading sector consumed 3.4%.

We import dry gas to satisfy shortfalls in our production and to meet demand in areas of northern Mexico that, due to their distance from the fields, can be supplied more efficiently by importing natural gas from the United States. We imported 422.0 million cubic feet per day of dry gas in 2009, a decrease of 5.6% from the 447.1 million cubic feet per day imported in 2008.

Pemex-Gas and Basic Petrochemicals also produces liquid hydrocarbons obtained from sweet natural gas and recovered in surface separating facilities, as well as liquid hydrocarbons condensed in natural gas pipelines. Our production of natural gas liquids, including stabilized condensates and reprocessing and other fractionating streams, increased from 376 thousand barrels per day in 2008 to 378 thousand barrels per day in 2009.

Pemex-Gas and Basic Petrochemicals processes sour condensates, which have a higher sulfur content, to produce stabilized sweet condensates. The volume of sour condensates we processed from Pemex-Exploration and Production and internal streams of Pemex-Gas and Basic Petrochemicals amounted to 40.6 thousand barrels per day in 2009, a 15.1% decrease from the 47.8 thousand barrels per day processed in 2008. Pemex-Gas and Basic Petrochemicals also processes sweet condensates at its Reynosa and Burgos facilities to produce solvents, naphtha and heavy naphtha.

57

In January 2007, Pemex-Gas and Basic Petrochemicals commenced construction of cryogenic plants numbers 5 and 6, each with a processing capacity of 200 million cubic feet per day. Cryogenic plant number 5 began operations in December 2008 and plant number 6 began commercial operations in February 2009. With the completion of these plants, the total cryogenic capacity at the Burgos gas processing center has reached 1,200 million cubic feet per day.

The Regulatory Law limits basic petrochemicals to the following nine products that are used in the petrochemical production process: ethane, propane, butane, pentanes, hexane, heptane, carbon black, naphthas and methane, when obtained from hydrocarbon reservoirs in Mexico and used as raw material for petrochemical industrial processes. All other petrochemical products may be produced by Pemex-Petrochemicals, by Pemex-Refining or by private sector companies. However, the Regulatory Law also allows companies that produce basic petrochemicals, as by-products of non-basic petrochemical production, to sell them either internally, within plants in the same unit or complex, or to sell them to Petróleos Mexicanos and the subsidiary entities.

Over the five years ended December 31, 2009, the value of Pemex-Gas and Basic Petrochemicals’ domestic sales was distributed as follows.

Private Sector Participation in Natural Gas Distribution

The Regulatory Law, as amended on May 12, 1995, provides that private and “social sector” companies may, with governmental authorization, store, distribute and transport natural gas, and may construct, own and operate natural gas pipelines, facilities and equipment. The regulations implementing this amendment went into effect on November 9, 1995.

Since 1997, the Regulatory Law has required us to provide the private sector with open access to our transportation system for distribution, ending our prior exclusive rights over the distribution lines. We continue to market natural gas and may develop natural gas storage systems.

In 1996, the Comisión Reguladora de Energía (Energy Regulatory Commission) approved the Gradual Access Program for 1996-1997, which required that we open access to our natural gas distribution system to the private sector and prohibited vertical integration between transportation and distribution. As a result, Pemex-Gas and Basic Petrochemicals’ distribution assets located within the following official distribution zones have been privatized: Chihuahua, Toluca, Saltillo, Nuevo Laredo, Río Pánuco, Norte de Tamaulipas, Distrito Federal, Valle de Cuautitlán, Texcoco, Querétaro, La Laguna, Bajío Norte, Puebla, Tlaxcala, Guadalajara, Piedras Negras and Ciudad Juárez. As of 1999, all of our natural gas distribution pipelines were opened to private sector use and there were no further distribution assets left to divest pursuant to the program, although a portion of these assets are still held in trust and the distribution assets located within Veracruz have not yet been divested.

59

The Energy Regulatory Commission is expected to put in place significant campaigns to promote the natural gas market in Mexico. These campaigns will include a new system for first-hand sales of natural gas. Although Pemex-Gas and Basic Petrochemicals, in coordination with the Energy Regulatory Commission, has informed clients of the advantages of moving from the current transitory scheme to the new permanent system, as well as designed mechanisms for clients to estimate their consumptions under the new system, only electrical sector customers have expressed interest. Pemex-Gas and Basic Petrochemicals is prepared to operate under the new system at such time as the Energy Regulatory Commission declares the effectiveness of the new system.

Pricing Decrees

Natural gas prices for domestic sale are calculated in accordance with directives issued by the Energy Regulatory Commission on July 20, 2009. These prices reflect natural gas opportunity costs and competitive conditions in international markets and at the point of sale.

Since 2003, price control mechanisms for LPG have been implemented through governmental decrees. On December 28, 2007, President Calderón issued a decree establishing the maximum LPG price for first-hand and end-user sales. The decree became effective in January 2008, and established a monthly price increase from January 2008 to May 2008 of Ps. 0.0317 per kilogram over the weighted average end-user price of LPG after taxes. From June 2008 to December 2008, the amount of these price increases varied from month to month.

On December 29, 2008, the Mexican Government issued a decree establishing a national weighted average end-user price of LPG before taxes of Ps. 8.92 per kilogram, effective January 2009. Subsequently, on January 9, 2009, the Mexican Government issued a decree modifying the national weighted average end-user price of LPG before taxes to Ps. 8.03 per kilogram, representing a discount of almost 10%. This decree also suspended the periodic increases in the retail price of LPG, beginning on January 12, 2009 and effective through December 31, 2009.

In January 2010, the Mexican Government issued a decree establishing the maximum weighted average end-user price of LPG before taxes of Ps. 8.08 per kilogram. Subsequently, from February to May 2010, the maximum price was increased by five Mexican cents per kilogram per month.

The Mexican Government could modify these price controls or impose additional price controls in the future.

Natural Gas Hedging Operations

Pemex-Gas and Basic Petrochemicals offers, as a value added service, various hedging contracts to its domestic customers to protect them against fluctuations in the prices of natural gas. For information on hedging contracts offered to natural gas domestic customers, see “Item 11—Quantitative and Qualitative Disclosures about Market Risk—Instruments Entered into for Trading Purposes.”

Investments

In nominal peso terms, Pemex-Gas and Basic Petrochemicals invested Ps. 3,941 million in 2009, as compared to Ps. 4,203 million in 2008, in projects primarily related to natural gas and condensates processing, transportation and storage. For 2010, the Mexican Government has approved Ps. 5,720 million in nominal terms of capital expenditures for Pemex-Gas and Basic Petrochemicals, including Ps. 1,869 million for the cryogenic plant at the Poza Rica gas processing complex.

Cryogenic Plant at the Poza Rica Gas Processing Complex (GPC)

In order to provide the infrastructure necessary to process the wet natural gas produced by the Aceite Terciario del Golfo project, Pemex-Gas and Basic Petrochemicals is constructing at the Poza Rica GPC a cryogenic plant, which will have a processing capacity of 200 million cubic feet per day of sweet wet gas, and a

60

liquids fractionating plant, which will be located on Pemex-Gas and Basic Petrochemicals’ property and utilizing the facilities of the Poza Rica GPC. This project also includes, among others, the construction of two storage tanks for liquid gas, each with a capacity of 20 thousand barrels, an ecological burner, an effluent treatment plant and supporting infrastructure. The tender for this project was awarded on May 15, 2009 to ICA Flúor Daniel and Linde Process Plants, Inc., in association, with the contract signed on June 12, 2009. Construction began on August 17, 2009, and the project is scheduled to be completed in August 2011.

Electric Energy Cogeneration Program

As part of our Programa de Cogeneración de Energía Eléctrica (Electric Energy Cogeneration Program), on August 28, 2008, we launched an international tender for the construction of our first large-scale cogeneration plant at the GPC at the Nuevo Pemex complex in the state of Tabasco. Pemex-Gas and Basic Petrochemicals will be able to use the electric energy generated by the plant at the GPC, and may use any surplus electric energy production in other PEMEX facilities.

The Electric Energy Cogeneration Program is a two-stage program. In the short term, the program is intended to permit us to reduce our reliance on energy supplied by the Federal Electricity Commission. Over the medium and long term, we expect that these large-scale cogeneration projects will permit us to replace inefficient equipment at the end of their useful lives and to sell excess energy production to the Federal Electricity Commission.

Petrochemicals

Capacity

At the end of 2009, Pemex-Petrochemicals owned the following: seven petrochemical complexes; one petrochemical unit for the production of non-basic petrochemical products; the Camargo petrochemical complex, which ceased operations nine years ago; and a petrochemical unit at Reynosa, which ceased operations in August 1998. At the end of 2009, Pemex-Petrochemicals owned 51 plants, including some that were not producing. Pemex-Petrochemicals had a total installed capacity of 13.96 million tons of petrochemical products per year in 2009, representing a decrease from 2008 as a result of the initiation of gasoline blend production at the Cangrejera petrochemical complex under a change in its processing program.

Pemex-Petrochemicals’ total production capacity for the last five years was distributed among its facilities as set forth below.

The total annual production of Pemex-Petrochemicals in 2009 was 11,486 thousand tons, which included 3,899 thousand tons of refined products. Our combined total annual petrochemical production (including all subsidiaries) decreased by 0.1%, from 11,973 thousand tons in 2008 to 11,956 thousand tons in 2009. Of this amount, Pemex-Petrochemicals produced 7,587 thousand tons, representing a 3.2% decrease from Pemex-Petrochemicals’ production of 7,841 thousand tons of petrochemical products in 2008. The remainder of these petrochemical products were produced by Pemex-Refining and Pemex-Gas and Basic Petrochemicals. The decrease in petrochemical production was a result of decreased production: (1) of ammonia, resulting from annual maintenance at the ammonia plants; (2) of ethane derivatives, in particular ethylene oxide, due to the integration of the ethylene oxide project at the Morelos petrochemical complex; (3) of vinyl chloride monomer at the Pajaritos petrochemical complex, as a result of certain operational difficulties; and (4) in the aromatics chain, due to (a) shutdowns for the annual maintenance program, (b) the shutdown of the paraxylene plant, because of market conditions, (c) modifications made in the gasoline blend production program and (d) preparations undertaken to ensure readiness of operations in order to comply the 2010 imported naphtha program for 2010. For information on Pemex-Gas and Basic Petrochemicals’ petrochemical production, see “—Gas and Basic Petrochemicals” above.

Investments

Pemex-Petrochemicals invested Ps. 2,052.9 million in 2009 in capital expenditures, of which Ps. 0.8 million corresponded to the Fondo de Aprovechamiento de Obras (Fund for Use of Infrastructure Works), Ps. 2.4 million corresponded to the Fondo de Ingresos Excedentes (Fund for Surplus Revenues) and Ps. 2,049.7 million was used in the following ongoing projects: expansion of the oxygen plant at the Morelos petrochemical complex; expansion at the same complex of the first phase of our ethylene oxide production capacity, from 225 thousand tons per year to 360 thousand tons per year; complementary projects at the same complex’s high density polyethylene production plant (swing plant) to produce 300 thousand tons per year of low and/or high density polyethylene; the expansion of the same complex’s ethylene plant production capacity, from 600 to 900 thousand tons per year (second phase); modernization and expansion of the aromatics train (first phase) at the Cangrejera

petrochemical complex, to increase that complex’s paraxylene production capacity from 240 thousand tons per year to 468 thousand tons per year; the expansion of that complex’s styrene plant production capacity, from 150 thousand tons per year to 250 thousand tons per year; and investments in security as well as maintaining capacity at Pemex-Petrochemicals’ facilities generally.

Pemex-Petrochemicals’ 2010 budget includes Ps. 4,780 million in capital expenditures, of which it has allocated Ps. 2,600 million to the expansion of aromatics capacity, Ps. 0.2 million to completion of the expansion of ethylene oxide capacity (first phase), Ps. 1,034.3 million to complementary project acquisitions, Ps. 865.8 million to maintaining plant production capacity and Ps. 279.7 million to modernization, optimization and infrastructure projects, among others.

Pemex-Petrochemicals expects that its investment budget for 2010 will allow it to meet its contractual and other commitments arising from the engineering and construction bidding processes in connection with the projects mentioned above.

Domestic Sales

In 2009, the value of the domestic sales of Pemex-Petrochemicals’ petrochemical products decreased by 25.1%, from Ps. 25,823.5 million in 2008 to Ps. 19,329.3 million in 2009. This decrease was primarily due to a reduction in the prices of ammonia, methanol, vinyl chloride monomer, ethylene, ethylene oxide, glycols, styrene and propylene, due to market conditions, as well as to a decrease in the volume of sales of ethylene oxide, glycols, ethylene, styrene, paraxylene, orthoxylenes and methanol. The decrease in ethylene oxide and glycols sales volume was due to lower production as a result of reconfiguration works in the related plant; in the case of ammonia, the decrease was due to plant maintenance taking longer than scheduled to complete; the decrease in ethylene sales was due to the shutdown of our principal customer’s plant for such product, due to market conditions; in the case of methanol, the decrease was due to market conditions; and aromatics sales decreased due to lower sales of styrene as a result of reduced purchases by our principal customer for such product and a lack of sales of paraxylene due to market conditions.

Over the five years ended December 31, 2009, the value of Pemex-Petrochemicals’ domestic sales was distributed as set forth in the table below. The sales of petrochemical products by Pemex-Gas and Basic Petrochemicals and Pemex-Refining, respectively, are included under “—Gas and Basic Petrochemicals” and “—Refining” above.

International Trading

The PMI Group

The PMI Group conducts international commercial activities for our crude oil, refined and petrochemical products, except for natural gas, which is marketed directly by Pemex-Gas and Basic Petrochemicals. The PMI Group’s main objective is to assist in maximizing our profitability and optimizing our operations through the use of international trade, facilitating our link with the international markets and pursuing new business opportunities in marketing our products. The PMI Group manages the international sales of our crude oil and petroleum products and acquires in the international markets those petroleum products that we import to satisfy domestic demand. Sales of crude oil are carried out through PMI. Sales and purchases of petroleum products in the international markets are carried out through P.M.I. Trading, Ltd., which also performs third-party trading, transportation and risk management activities.

Exports and Imports

PMI purchases crude oil from Pemex-Exploration and Production and then sells it to PMI’s customers. PMI sold an average of 1,222 thousand barrels per day of crude oil in 2009, which represented 47.0% of our total crude oil production.

The following tables set forth the composition and average prices of our crude oil exports for the periods indicated.

PMI sells a significant percentage of its crude oil under evergreen contracts, which can be terminated by either party pursuant to a three month phase-out clause. For more detailed information regarding PEMEX’s sales of crude oil, see “PEMEX’s Customers and Receivables.” PMI sells crude oil on a Free On Board (FOB) basis (at the shipping point).

Beginning in 1998, PMI entered into several long-term Maya crude oil supply agreements pursuant to which the purchasers have agreed to undertake projects to expand the capacity of their respective refineries to upgrade residue from Maya crude oil. Under these agreements, PMI provided purchasers with certain support mechanisms to protect, in certain adverse market conditions, the purchasers’ investments. Upon the expiration of these contracts, the commercial relationship continues under evergreen contracts that do not contain support mechanisms. These agreements include:

• An agreement with Port Arthur Coker Co., signed on March 10, 1998, which was assigned to Valero Energy Corporation on November 1, 2005, to supply its Port Arthur, Texas refinery with Maya crude oil for a period of eight years following project completion, which occurred in March 2001; the amount of Maya crude oil supplied was adjusted every six months. On December 31, 2007, the volume to be supplied was set at 188 thousand barrels per day and on May 1, 2008, the volume was adjusted to 177 thousand barrels per day. This agreement expired in March 2009.

• An agreement with Pecten Trading Company, which is a trading subsidiary of Shell Oil Company, executed on May 1, 1999, and an agreement with P.M.I. Norteamérica, S.A. de C.V., to supply the Deer Park refinery joint venture with a total of approximately 200 thousand barrels per day of Maya crude oil, 50 thousand barrels of which were under the support mechanism for such contract for a period of seven years following project completion, which occurred in April 2001. Effective May 2008, the support mechanism ended, and the contract volume was set at 220 thousand barrels per day from 2009 to 2011. This agreement will expire in 2023.

• An agreement with Valero Marketing and Supply Company and Valero Refining-Texas, L.P., executed on December 17, 2001, to supply their Texas City, Texas refinery with approximately 90 thousand barrels per day of Maya crude oil for a period of five years following project completion, which occurred in January 2004. This agreement expired in January 2009, though PMI currently has an evergreen contract to supply 200 thousand barrels per day to Valero Marketing and Supply Company.

• An agreement with Hunt Crude Oil Supply Company, signed on December 19, 2005, to supply its refinery in Tuscaloosa, Alabama, with approximately 14 thousand barrels per day of Altamira crude oil for a period of five years following project completion, which occurred in June 2007.

• An agreement with Chevron Products Company, a division of Chevron U.S.A. Inc., executed and delivered on October 1, 2008, to supply its refinery in Pascagoula, Mississippi with approximately 145 thousand barrels per day of Maya crude oil for a period of three years, with an option for an additional year subject to the express agreement of both parties.

We expect to fulfill the majority of these supply commitments with proved developed reserves. In addition, we anticipate using proved undeveloped reserves and spot market purchases to fulfill these commitments.

These long-term crude oil supply agreements further our strategy of enhancing the export value of Mexican heavy crude oil in relation to the value of other grades of oil by creating incentives for refiners to invest in new high-conversion refineries, which are capable of upgrading a significant proportion of the residue produced from processing Maya and Altamira crude oil.

Crude oil exports decreased by 12.9% in 2009, from 1,403.4 thousand barrels per day in 2008 to 1,222.1 thousand barrels per day in 2009, mainly as a result of lower crude oil production.

Natural gas imports decreased by 5.6% in 2009, from 447.1 million cubic feet per day in 2008 to 422.0 million cubic feet per day in 2009, due to increased production by Pemex-Gas and Basic Petrochemicals’ plants that made it unnecessary to increase natural gas imports. We exported 66.5 million cubic feet per day of natural gas in 2009, a decrease of 38.1% as compared to natural gas exports in 2008 of 107.4 million cubic feet per day.

In 2009, exports of refined products increased by 33%, from 184.1 thousand barrels per day in 2008 to 244.8 thousand barrels per day in 2009, due to increased sales of fuel oil and diesel. Imports of refined products decreased by 7.6% in 2009, from 548.2 thousand barrels per day in 2008 to 506.4 thousand barrels per day in 2009, due to decreased demand for jet fuel, gasoline and diesel. As of January 2007, clean fuels specifications for gasoline and diesel for transportation were established in Mexico. Since that time, imports of ultra-low sulfur diesel and ultra-low sulfur premium gasoline have been required to meet domestic demand. During 2010, import volumes of refined products are expected to remain stable as compared to 2009, with a slight upward trend due to the recovery of the Mexican economy. We also expect a decrease in exports of residuals, due to a reduction in products supplied by PEMEX.

Imports of natural gas decreased in value by 55.5% during 2009, mainly as a result of increased production by Pemex-Gas and Basic Petrochemicals’ plants.

In 2009, imports of refined products decreased both in value, by 41.1%, and in volume, by 7.6%. These decreases were due to lower demand for jet fuel, gasoline and diesel. Production from the national refining system increased slightly with respect to previous years, leading to decreased demand for imported products. Exports of refined products decreased in value by 14.3% in 2009, in line with lower prices of these products in the international market. Our net imports of refined products for 2009 totaled U.S. $7,993.1 million, a 50.6% decrease from the refined products trade deficit of U.S. $16,175.9 million in 2008.

In 2009, our exports of petrochemical products increased by 44.4%, from 539.6 thousand metric tons in 2008 to 779.4 thousand metric tons in 2009, while imports of petrochemical products also increased by 29.2%, from 439.8 thousand metric tons in 2008 to 568.3 thousand metric tons in 2009. Petrochemical exports increased in 2009, due to higher sales of ethylene and sulfur. The increase in ethylene exports resulted from a larger production surplus due to process adjustments and maintenance works in the derivatives processing plants. The increase in sulfur exports resulted from a decrease in domestic demand.

Imports of petrochemical products increased in 2009, due to greater requirements for isobutane (a raw material in the production of alkylates, butane-1 and hexane-1), for monomers used as additives in Pemex-Petrochemicals’ linear low-density polyethylene plant, for toluene, which is supplied to the solvents market, and to increased demand for ammonia and lower ammonia production.

Hedging Operations

P.M.I. Trading, Ltd. engages in hedging operations to cover its price exposure in the trading of petroleum products, as well as to protect the revenues of other companies within the PMI Group and to ensure the fulfillment of contractual obligations. The internal policies of P.M.I. Trading, Ltd. establish a limit on the maximum capital at risk. Capital at risk is calculated daily in order to compare the actual figures with the aforementioned limit. Internal controls include a risk comptroller responsible for ensuring compliance, an internal auditing department and a risk management committee. See “Item 11—Quantitative and Qualitative Disclosures about Market Risk—Commodity Price Risk.”

Transportation and Distribution

Our pipelines connect crude oil and natural gas producing centers with refineries and petrochemical plants, and our refineries and petrochemical plants with Mexico’s major cities. At the end of 2009, our pipeline network measured approximately 65,339 kilometers in length. Of these pipelines, 51,691 kilometers are currently operational and 13,647 kilometers are out of operation. Most of the pipelines out of operation are classified as being in “stand-by” status, which occurs when there is a decline in production in a field where the pipeline is located or when transportation service is irregular, making operation of the pipeline unprofitable. Once production is restored in such field, we change the status of the pipelines back to “operational.” Approximately 8,417 kilometers of the pipelines currently in operation transport crude oil, 10,425 kilometers transport petroleum products and petrochemicals, 14,452 kilometers transport natural gas, 1,811 kilometers transport LPG, 1,151 kilometers transport basic petrochemicals, 1,706 kilometers are crude oil and natural gas gathering pipelines, 13,003 kilometers are production lines (discharge lines) and 725 kilometers correspond to other services, including aqueducts. Ownership of the pipelines is distributed among the subsidiary entities according to the products they transport.

71

Petróleos Mexicanos has been working to implement a Pipeline Integrity Management Plan, which provides that detailed records covering all periods from the design stage to current conditions must be maintained in order to ensure that optimal investments are being made in pipelines. The Pipeline Integrity Management Plan is derived from the guidelines of American Petroleum Institute (API) Standard 1160, “Managing System Integrity for Hazardous Liquid Pipelines,” and from American Society of Mechanical Engineers (ASME) B31.8S, “Managing System Integrity of Gas Pipelines.” In Mexico, Norma Oficial Mexicana (Mexican Official Standard) NOM-027-SESH-2010, “Integrity Management of Hydrocarbons Collection and Transportation Pipelines,” (which we refer to as NOM-027), became effective in June 2010.

The Pipeline Integrity Management Plan consists of the following stages:

• information gathering and database development;

• segmentation and identification of threats that might affect pipeline integrity, safety and operation;

• identification of high consequence areas;

• risk and reliability assessment;

• integrity assessment;

• programming of maintenance and risk mitigation measures;

• subsequent assessments;

• repetition of the integrity management process; and

• ongoing monitoring during all stages.

In this respect, Petróleos Mexicanos and the subsidiary entities have made considerable progress in satisfying the requirements of NOM-027, concerning risk assessment. We have analyzed 60% of our pipeline network in length terms, undertaking at the same time several of the measures relating to the other stages of the Pipeline Integrity Management Plan. In addition, we have satisfied the documentation requirements of this standard.

The transportation of crude oil, natural gas and other products through a pipeline network is subject to leaks and spills in soil. See “Item 3—Key Information—Risk Factors— Risk Factors Related to the Operations of PEMEX.” In 2009, we incurred a total of U.S. $375.4 million of expenditures for the remediation and maintenance of our pipelines network and we have budgeted an additional U.S.$ 423.3 million of expenditures in 2010. For more information on recent problems with our pipeline network, see “Item 3—Key Information—Risk Factors—PEMEX is an integrated oil and gas company and is exposed to production, equipment and transportation risks and deliberate acts of terror” above and “—Environmental Regulation—Environmental Liabilities” below.

During 2009, we transported approximately 76.8 billion tons per kilometer of crude oil to be processed in our refining system and petroleum products to satisfy domestic demand, as compared to the 74.6 billion tons per kilometer carried in 2008. Of the total amount we transported in 2009, we carried 62.0% through pipelines, 30.3% by vessels and the remainder by train tank cars as well as tank trucks.

At the end of 2009, we owned ten refined product tankers and had leased another nine. We also owned 77 major wholesale storage centers, 19 liquefied gas terminals and five maritime terminals. These facilities, together with our pipeline network, constitute our hydrocarbon transportation and distribution infrastructure.

PEMEX Corporate Matters

In addition to the operating activities that we undertake through the activities of our subsidiary entities and subsidiary companies, we have certain centralized corporate operations that coordinate general labor, safety, insurance and legal matters.

72

Industrial Safety and Environmental Protection

Petróleos Mexicanos’ Corporate Operations Office is responsible for planning, conducting and coordinating programs to:

• foster a company culture of safety and environmental protection;

• improve the safety of our workers and facilities;

• reduce risks to residents of the areas surrounding our facilities; and

• protect the environment.

We intend to develop further the industrial safety and environmental programs for each subsidiary entity. The environmental and safety division of each subsidiary entity coordinates closely with the Corporate Operations Office.

Insurance

We maintain a comprehensive property and civil liability insurance program for onshore and offshore properties and liabilities. All onshore properties, such as refineries, processing plants, pipelines and storage facilities are covered, as are all of our offshore assets, such as drilling platforms, rigs, gas gathering systems, maritime terminals and production facilities. Our insurance covers risks of sudden and accidental physical destruction to all properties, as well as against all risk of physical loss, including as a consequence of purposeful terrorist acts. This insurance also provides coverage for the contents of pipelines, storage facilities and wells, and any liabilities of PEMEX arising from such acts. Our offshore general and civil liability insurance also covers extraordinary costs related to the operation of offshore wells, such as control and re-drilling costs, evacuation expenses and liability costs associated with spills. We also maintain protection and indemnity insurance for our full marine fleet, as well as life insurance, automobile and heavy equipment insurance, and cargo and marine hull insurance.

In accordance with Mexican law, we have entered into all of our insurance contracts with Mexican insurance carriers. These policies have limits of U.S. $2.0 billion for onshore property, U.S. $1.3 billion for offshore property, U.S. $0.3 billion for extraordinary costs related to the operation of offshore wells, U.S. $1.0 billion for protection and indemnification for marine-related liabilities, U.S. $0.5 billion for civil liabilities, U.S. $0.5 billion for offshore terrorist acts and U.S. $0.3 billion for onshore terrorist acts. Limits of insurance policies purchased for each category of risk are determined using professional risk management assessment surveys conducted by international companies on an annual basis and the market capacity available per risk.

Since June 2003, we have not maintained business interruption insurance, which in the past compensated us for loss of revenues resulting from damages to our facilities. We have discontinued such insurance based on the following factors: (1) the existence of mitigating factors across all of our facilities, (2) the nature and operation of our facilities, such as the ability of any of our six refineries to compensate for the loss of any one refinery and the physical separation of plants within the refineries, and (3) the excess processing capacity available across our different lines of business, vis-a-vis the restricted coverage available in the international reinsurance markets. These factors led us to conclude that the benefits of this type of coverage were outweighed by the costs. Instead, we purchase ad-hoc business interruption mitigation insurance coverage, which compensates us for the additional expenses necessary to recover our production capabilities in the shortest time possible.

All PEMEX insurance policies are in turn reinsured through Kot Insurance Company, AG, which we refer to as Kot AG. Kot AG is a wholly owned subsidiary company organized under the laws of Switzerland (previously organized under the laws of Bermuda as Kot Insurance Company, Ltd.), which is used as a risk management tool to structure and distribute risks across the international reinsurance markets. The purpose of Kot AG is to reinsure policies of the local insurance carriers of Petróleos Mexicanos and maintain control over the cost and

73

quality of the insurance covering our risks. Kot AG reinsures over 96.8% of its reinsurance policies with unaffiliated third party reinsurers. Kot AG carefully monitors the financial performance of its reinsurers and actively manages counterparty credit risk across its reinsurance portfolio to ensure its own financial stability and maintain its A- rating from Standard & Poor’s (which we refer to as S&P). Kot AG maintains solid capitalization and solvency margins consistent with guidelines provided by Swiss insurance authorities and regulations. Kot AG’s net risk retention is capped at U.S. $120 million and is diversified across different reinsurance coverages to mitigate potential aggregation factors.

Property, Plants and Equipment

General

Substantially all of our property, consisting of refineries, storage, production, manufacturing and transportation facilities and certain retail outlets, is located in Mexico, including Mexican waters in the Gulf of Mexico. The location, character, utilization and productive capacity of our exploration, drilling, refining, petrochemical production, transportation and storage facilities are described above. See “—Exploration and Production,” “—Refining,” “—Gas and Basic Petrochemicals,” “—Petrochemicals” and “—Transportation and Distribution.”

Reserves

Under Mexican law, all crude oil and other hydrocarbon reserves within Mexico are owned by the Mexican nation and not by us. Pemex-Exploration and Production has the exclusive right to exploit those reserves under the Regulatory Law and related laws and regulations. Our estimates of Mexico’s hydrocarbon reserves are described under “—Exploration and Production—Reserves” above.

74

GENERAL REGULATORY FRAMEWORK

The Mexican Government and its agencies closely regulate and supervise our operations. The Ministry of Energy monitors our activities and the Secretary of Energy acts as the chairperson of the Board of Directors of Petróleos Mexicanos. The SHCP approves the annual budget and financing program of Petróleos Mexicanos and the subsidiary entities. The Mexican Government incorporates the annual budget and financing program of Petróleos Mexicanos and the subsidiary entities into its budget, which the Mexican Congress must approve each year. The Mexican Government is not, however, liable for the financial obligations that we incur.

Under the Petróleos Mexicanos Law, Petróleos Mexicanos will each year provide to the SHCP, through the Ministry of Energy, its projected financial balance for each of the next five years. If Petróleos Mexicanos maintains compliance with these annual balance goals, and if its wage and salary expenditures have not increased, then the Board of Directors of Petróleos Mexicanos will be permitted to approve adjustments to its own budget and those of the subsidiary entities without approval from the SHCP. If these same conditions are met, the Board of Directors of Petróleos Mexicanos will also be permitted to authorize, without SHCP approval, increases in the expenditures of Petróleos Mexicanos and the subsidiary entities to the extent that their revenues exceed the amounts contemplated in the budget.

The Secretaría de Medio Ambiente y Recursos Naturales (Ministry of the Environment and Natural Resources), which we refer to as SEMARNAT, in conjunction with other Mexican federal and state authorities, regulates our activities that affect the environment. The President of Mexico appoints the comisario (supervising officer) of Petróleos Mexicanos.

In addition to the regulatory powers that the Energy Regulatory Commission already has over natural gas and LPG activities, this Commission is now vested, pursuant to the amendments to the Energy Regulatory Commission Law, with the authority to regulate: (1) first-hand sales of gas, fuel oil and basic petrochemicals; (2) pipeline transportation and distribution of gas and refined products, as well as storage of such products to the extent that this is directly linked with such pipeline transportation and distribution, or forms an integral part of the importation and distribution terminals of such products; and (3) pipeline transportation and distribution of biofuels, as well as storage of such products to the extent that this is directly linked with such pipeline transportation and distribution, or forms an integral part of the importation and distribution terminals of such products.

The National Hydrocarbons Commission Law, which became effective on November 29, 2008, provides for the establishment of a new National Hydrocarbons Commission, which is responsible for regulating and supervising hydrocarbons exploration and exploitation as well as the processing, transportation and storage activities directly related to exploration and exploitation projects. The members of the National Hydrocarbons Commission were appointed on May 20, 2009 by President Calderón. On August 28, 2009, the Reglamento Interno de la Comisión Nacional de Hidrocarburos (Internal Regulation of the National Hydrocarbons Commission) was published in the Official Gazette of the Federation. This regulation establishes, among other things, the National Hydrocarbons Commission’s organizational structure and the activities to be performed by its respective areas.

The Auditoría Superior de la Federación (Superior Audit Office of the Federation, or the ASF) reviews annually the Cuenta Pública (Public Account) of the Mexican Government entities, including Petróleos Mexicanos and the subsidiary entities. This review focuses mainly on the entities’ compliance with budgetary benchmarks and budget and accounting laws. The ASF prepares reports of its observations based on this review. The reports are subject to our analysis and, if necessary, our clarification and explanation of any issues raised during the audit. Discrepancies in amounts spent may subject our officials to legal sanctions. However, in most instances, the observed issues are explained and clarified. The financial information provided to the ASF is prepared in accordance with Mexican Governmental Standards applicable to Mexican public sector entities, which differ in several respects from Mexican FRS. As a result, our financial statements reflect different financial data than those included in the Public Account.

75

ENVIRONMENTAL REGULATION

Legal Framework

We are subject to various laws related to the environmental protection of natural resources, as well as the management of hazardous and non-hazardous wastes. In particular, Petróleos Mexicanos and the subsidiary entities are subject to the provisions of the Ley General del Equilibrio Ecológico y la Protección al Ambiente (General Law on Ecological Equilibrium and Environmental Protection), which we refer to as the Environmental Law, the regulations issued thereunder and several technical environmental norms issued by the SEMARNAT. We are also subject to the Law of Use of Renewable Energy and Financing of the Energy Transition and the Sustainable Use of Energy Law, each of which became effective on November 29, 2008, and we will be subject to the regulations that the Ministry of Energy, in coordination with SEMARNAT, is expected to issue thereunder. The Secretaría de Salud (Ministry of Health), the Secretaría de Comunicaciones y Transportes (Ministry of Communications and Transportation), the Secretaría de Marina (Ministry of the Navy) and the Ministry of Energy assist the SEMARNAT in its functions. In addition, Petróleos Mexicanos and the subsidiary entities are subject to the environmental laws and regulations issued by the governments of each state of Mexico where our facilities are located.

The Environmental Law and related regulations require that we obtain certain authorizations from the SEMARNAT before we carry out any activity that may have an adverse effect on the environment. In particular, these environmental regulations apply to chemical, petrochemical, crude oil refining and extraction activities, as well as the construction of crude oil and natural gas pipelines. Before authorizing a new project, the SEMARNAT requires the submission of an environmental impact analysis and any other information that it may request. The SEMARNAT is entitled to independently grant or deny its authorization of any activity.

The environmental regulations that apply generally to Mexican industry apply to us. These regulations specify, among other matters, permissible levels of emissions, water discharges and hazardous substances discharges as well as atmospheric pollution level limits. The technical regulations for oil and petrochemical industries set forth maximum permissible levels of pollution in residual water discharges and natural gas emissions. These regulations also establish procedures for measuring pollution levels.

Mexico generally updates and revises its environmental regulatory framework as necessary, and we participate with the Mexican Government in developing environmental regulations that are related to our activities. The new Law of Use of Renewable Energy and Financing of the Energy Transition and the Sustainable Use of Energy Law are designed to further Mexico’s transition to cleaner, more environmentally friendly fuels and renewable energy sources. On January 30, 2006, the SEMARNAT issued Mexican Official Standard NOM-086-SEMARNAT-SENER-SCFI-2005, which sets forth environmental specifications for fossil fuels. In order to comply with this Standard, we will be required to meet certain targets for the optimal use of energy in all of our processes and activities as well as to meet domestic market demand for low-sulfur fossil fuels.

In April 1997, the SEMARNAT issued regulations governing the procedures for obtaining an environmental license, under which new industrial facilities can comply with all applicable environmental requirements by way of a single administrative procedure. Each environmental license integrates all of the different permits, licenses and authorizations related to environmental matters for a particular facility. Since these regulations went into effect, we have been required to obtain an environmental license for any new facility, while our facilities that existed prior to the effectiveness of these regulations are not subject to this obligation.

Federal and state authorities in Mexico may inspect any facility to determine compliance with the Environmental Law, local environmental laws, regulations and technical environmental regulations. Violations or non-compliance with the legal provisions may result in the application of substantial fines, temporary or permanent shutdown of a facility, required capital expenditures to minimize the effect of our operations on the environment, cleanup of contaminated land and water, cancellation of a concession or revocation of authorization

76

to carry out certain activities and, in certain cases, criminal prosecution of employees and individuals. See “Item 3—Key Information—Risk Factors—Risk Factors Related to the Operations of PEMEX—PEMEX’s compliance with environmental regulations in Mexico could result in material adverse effects on our results of operations.”

On November 28, 2007, the SEMARNAT issued NOM-148-SEMARNAT-2006 (which we refer to as NOM-148), which establishes standards for sulfur recovery in all refineries. The refineries located in Cadereyta, Nuevo León; Ciudad Madero, Tamaulipas; Tula, Hidalgo; and Salamanca, Guanajuato are currently in compliance with NOM-148 and the refineries located in Minatitlán, Veracruz and Salina Cruz, Oaxaca will be in compliance in 2010. Compliance with NOM-148 resulted in costs to Petróleos Mexicanos and the subsidiary entities of approximately Ps. 450 million in 2008 and Ps. 396 million in 2009, related to the rehabilitation, optimization and construction of new sulfur recovery plants and the construction of new plants and their corresponding installations. We expect to spend an additional Ps. 1,156 million in 2010 and 2011 to maintain and bring our remaining facilities into compliance with NOM-148.

Global Climate Change

In May 2007, the Federal Executive Office submitted its Estrategia Nacional de Cambio Climático (National Climate Change Strategy), which identified various opportunities to mitigate and adapt to climate change, as well as noted Mexico’s participation in the international community with respect to climate change awareness.

Since the National Climate Change Strategy was published, the various government offices that participate in the Comisión Intersecretarial de Cambio Climático (Inter-Ministry Climate Change Commission, which we refer to as the CICC) have worked to develop the Programa Especial de Cambio Climático 2009-2012 (Special Climate Change Program for 2009-2012, which we refer to as the PECC). On August 28, 2009, SEMARNAT issued the PECC, which will allow us to consolidate agreements, reinforce already negotiated commitments and identify, upon further consideration, new measures and additional changes necessary to progressively reach adequate greenhouse gas emissions levels under the National Climate Change Strategy.

We have identified several activities and projects to be undertaken in respect of issues addressed by the chapter of the PECC relating to mitigation measures, including increased energy efficiency, sour gas re-injection, co-generation and reduction in fugitive emissions, and we have set a goal of reducing carbon dioxide emissions by 9.94 million tons per year by 2012. During 2009, we reduced carbon dioxide emissions by an estimated 4.5 million tons, which represents progress of approximately 45% toward our goal for such annual reductions by 2012, primarily as a result of more efficient gas use. Also addressed in this chapter of the PECC is the goal of increased adaptability by energy sector participants in responding to climate change’s effects by designing and implementing: contingency programs in case of extreme hydrometeorological events; strategies of territorial planning and ecological territorial planning; as well as a vulnerability map reflecting the potential effects of climate change.

PEMEX’s Internal Monitoring

We believe that we are currently in substantial compliance with current federal and state environmental laws as those laws have been historically interpreted and enforced. We maintain an organizational structure that permits us to implement and monitor our environmental program. The subsidiary entities have specialized departments, depending on the size and geographic distribution of their respective sites, which implement their own environmental programs and conduct internal environmental audits and inspections of their sites and their immediate surroundings based on the standards of the SEMARNAT. When these internal audits reveal deficiencies, the subsidiary entities take the necessary remedial actions to eliminate these deficiencies. If soil or bodies of water are contaminated at levels that exceed the levels stipulated in the applicable regulation, the remediation requirements derived from these internal audits and inspections are recorded in our financial statements as environmental liabilities when they are known and estimable.

77

We maintain an internal structure to identify and solve environmental problems and we retain external consultants to perform operational audits at our industrial plants, including cost estimates for remedying any shortfall in compliance with Mexican environmental laws. Such remedies can include improving the operating efficiency of plants, cleaning up contaminated land and water and capital expenditures to minimize the effect of our operations on the environment.

In addition to our internal monitoring structure for identifying affected areas, areas of non-compliance and improvement opportunities, Petróleos Mexicanos and the subsidiary entities’ environmental program is subject to the review of the Procuraduría Federal de Protección al Ambiente (Office of the Federal Attorney for Environmental Protection, which we refer to as PROFEPA). PROFEPA administers the Mexican environmental regulatory rubric and establishes acceptable standards of environmental remediation. Although PROFEPA has the authority to review and inspect remediation works performed by us, and compliance with permitted contamination levels established by laws and regulations, it does not determine our environmental liabilities. We maintain proper records of all of the studies, estimations, performed works and any other information that PROFEPA may request from time to time.

Since 1993, we have participated in the National Program of Environmental Auditing, a voluntary environmental audit program, with PROFEPA. As each environmental audit is completed, we send the audit report (which includes the estimated costs for remedying environmental anomalies) to PROFEPA for its review and approval. After approval by PROFEPA, we review the audits and determine which findings can be resolved by changing current plant or drilling operations and implementing the current capital expenditures plan. If the audit report is approved by PROFEPA, we negotiate a corrective action plan with PROFEPA, stipulating the time period, amounts to be expended and the steps to be taken to bring each site into compliance. As of December 31, 2009, Petróleos Mexicanos and the subsidiary entities were in the process of auditing a total of 735 facilities with the objective of obtaining the same number of “clean industry” certificates. As of the same date, 109 of these certificates were effective, 102 were in the process of re-certification and 524 were in the process of certification, with audits begun but not yet complete. From the institution of the program through December 31, 2009, corrective action plans for 211 audits had been implemented and all of these sites had received or retained “clean industry” certifications from PROFEPA. We will continue including new facilities under this program as we expand our activities in the areas of exploration, exploitation, refining and distribution of hydrocarbons.

During 2009, we experienced 216 environmental incidents, the fewest in the last five years. The number of such events decreased by 34% from 2008 to 2009. This was due in part to the application of strategies focused on improving the integrity and operation of our pipeline systems.

Petróleos Mexicanos experienced two major incidents during 2009, one of which took place at a Pemex-Exploration and Production facility and the other at a Pemex-Refining facility. The incident that occurred at Pemex-Exploration and Production’s facility involved a 16-inch diameter oil pipeline located in the municipality of Cunduacán in the State of Tabasco. A rupture in the pipeline caused spillage totaling 15,000 barrels of crude oil. The major incident that occurred at Pemex-Refining’s distribution facilities was a rupture in an 8-inch diameter pipeline located in the municipality of Guaymas in the State of Sonora. This incident caused the spillage of 6,272 barrels of distillates. However, in each case, and in coordination with the relevant state government, the military, civil protection services and local authorities, among others, we implemented an emergency action plan which reinforced the existing emergency procedures and helped to isolate the damaged areas and to evacuate nearby towns in a very short period of time. In this way, damage to local residents and properties was significantly reduced. In the Pemex-Refining case, PROFEPA requested that we initiate an environmental impact evaluation.

In order to protect itself from civil environmental liabilities, Petróleos Mexicanos obtains insurance covering most of the expenses directly related to such incidents. This coverage does not, however, cover the deductible and those expenses excluded from the insurance policies, such as fines, public relations expenses and site clean-up not directly related to the incident, among others. For information relating to our environmental liabilities, see “—Environmental Liabilities” below. The majority of our remediation activities in connection

78

with the two major 2009 incidents described above have been completed. However, certain related legal proceedings are still pending resolution by Mexican environmental authorities, as a result of various administrative delays, including site analysis and other investigations into the causes of the incidents.

With a goal of achieving zero incidents, injuries, emissions of pollutants and illnesses for all of our work centers, in January 2006, we began to implement the PEMEX Safety, Health and Environmental Protection System (which we refer to as the PEMEX-SSPA), as well as the revision of and adherence to root-cause analysis; process safety management, with strong emphasis on mechanical integrity; environmental protection; occupational health; operational discipline; effective audits; emergency response plans; protection tests; and risk analysis systems. The PEMEX-SSPA includes the incorporation of 12 of the worldwide oil and gas industry’s best practices in preventive and corrective safety measures. The PEMEX-SSPA is comprised of three subsystems: Process Safety Management (SASP), Health Management (SAST) and Environmental Management (SAA). During 2007, we began to implement improvements to the PEMEX-SSPA and added a process management system as a complementary process, in order to supervise and coordinate the three aforementioned subsystems. In addition, we established guidelines to regulate the functions and activities of the areas involved in order to implement and monitor the PEMEX-SSPA.

During 2009, we continued implementing the PEMEX-SSPA and performed the following principal related activities:

• consolidated the organizational structure of our environment, health and security personnel throughout all levels of PEMEX;

• addressed issues concerning improvement in observance of operating discipline, especially those critical to the operation of the PEMEX-SSPA;

• provided the majority of our employees with training in the PEMEX-SSPA;

• incorporated an additional principle concerning contractors to our PEMEX-SSPA policies;

• measured the degree of implementation of all PEMEX-SSPA subsystems, as well as formulated and executed related plans therein, in order to promote systemic improvement; and

• improved the quality of execution of our Effective Safety Audits Program throughout all PEMEX facilities.

As a result of the above actions, our accident frequency rate decreased by 10.6% from 2008 to 2009, from 0.47 to 0.42 injuries per million man hours worked with exposure to risk. The accident frequency rate is the number of accidents that result in incapacitating injuries per million man hours of risk exposure during the relevant period. An incapacitating accident is a sudden or unexpected event that provokes a bodily injury, functional disability or death, immediately or at a later time, while working or as a result of work. Risk exposure man hours are the number of hours worked by all personnel, inside or outside of working facilities, during and outside standard working hours, including overtime hours. The lost days due to injuries indicator also decreased from 2008 to 2009, by 3.7%, from 27 to 26 lost days per million man hours worked with exposure to risk. The lost days due to injuries indicator is the number of days lost per million man hours of risk exposure during the relevant period. Lost days are those missed due to medical incapacity as a result of work accident injuries or rewarded as compensation for partial, total or permanent incapacity, or for death.

As a result of the implementation of the PEMEX-SSPA, our contractors also reported a decrease in their accident frequency rate from 2008 to 2009, of 32%, from 0.75 to 0.51 injuries per million man hours worked with exposure to risk.

Other than as disclosed herein, there are currently no material legal or administrative proceedings pending against us with respect to any environmental matters.

Environmental Liabilities

At December 31, 2009, our estimated and accrued environmental liabilities totaled Ps. 6,032.92 million. Of this total, Ps. 2,398.55 million were attributable to Pemex-Exploration and Production, Ps. 3,605.87 million to Pemex-Refining, Ps. 22.40 million to Pemex-Gas and Basic Petrochemicals and Ps. 6.10 million to Pemex-Petrochemicals. There were no environmental liabilities at the subsidiary company level. The following tables detail our environmental liabilities by subsidiary entity and operating region at December 31, 2009.

Our estimates of environmental liabilities include cost estimates for general and site-specific evaluation studies and the corresponding remediation. The remediation sites consist of sites identified in the audit process described above, as well as those previously identified sites in more mature petroleum operating areas that were not cleaned up in the past. Our environmental liabilities also include the elimination of holding ponds created by abandoned petroleum wells. Additionally, our environmental liabilities include an accrual for information requested and received periodically from field managers as to probable environmental liabilities identified in their respective areas of responsibility. We accrue environmental liabilities when sufficient basic knowledge is available to form a preliminary estimation as to remediation cost. Although the full potential scope of the remediation cost may not be known with certainty, these accruals are made when the liability is probable and the amount is reasonably estimable, in accordance with Bulletin C-9 “Liabilities, provisions, contingent assets and liabilities and commitments” for Mexican FRS purposes and with ASC Topic 450 “Contingencies” for U.S. GAAP purposes. These estimated liabilities include assumptions resulting from an initial evaluation of damage, including land acreage to be remediated, depth of contamination and type of contamination. While the initial evaluation is extensive, there is a possibility that the actual scope of remediation could vary depending upon information gathered during the remediation process. For a further discussion of our environmental liabilities, see Note 21 II(c) to our consolidated financial statements included herein.

Unasserted or additional claims are not reflected in our identified liabilities. We are not aware of any such claims that would be of such magnitude as to materially affect our estimates of environmental liabilities.

At the end of 2009, we were not aware of uncertainties with respect to joint and several liabilities that could affect our assessment of environmental contingencies or otherwise result in a major environmental liability. We are responsible for all production, processing, storage and distribution of petroleum and its derivatives in Mexico. As a result, we believe we are positioned to know immediately of any claims and are therefore directly accountable for any claims that may be brought against us.

81

The timing of remediation or cleanup of the sites accounted for in these environmental liabilities is dependent upon the annual budget assigned to us by the Mexican Congress.

Carbon Dioxide Emissions Reduction

Emission Reduction Purchase Agreements

In 2000, Mexico ratified the Kyoto Protocol to the United Nations Framework Convention on Climate Change (which we refer to as the Kyoto Protocol) as a non-Annex B country. Accordingly, Mexico is not subject to emissions caps under the Kyoto Protocol, but Mexican companies, such as PEMEX, are allowed to develop Clean Development Mechanism (CDM) projects. These CDM projects generate carbon dioxide emissions-reductions certificates or credits that can be traded in international markets.

In 2009, we signed three emission reduction purchase agreements for the marketing of carbon dioxide emission-reduction certificates. Two of these agreements are with Carbon Solutions de México and the other is with Statoil. Under these agreements, we will sell emission reduction certificates to be generated by the following three projects that could potentially reduce greenhouse gas emissions: increasing thermal efficiency and recovery of combustion gases at the Dos Bocas Marine Terminal; installing dry seals in gas compressors; and undertaking a cogeneration project at the Ciudad Pemex GPC. These projects would potentially reduce greenhouse gas emissions by more than 373 thousand tons annually. Each of these three projects is in the design phase.

Social Responsibility

Petróleos Mexicanos has implemented various initiatives in the area of corporate social responsibility, primarily with respect to the protection and preservation of the environment, community relations, ethical work practices, respect for labor rights and the general promotion of quality of life for employees. In particular, we note the following specific actions taken by Petróleos Mexicanos in 2009:

• We contributed Ps. 1.5 billion to a variety of charities and development projects in the communities in which we carry out our activities, including the following projects:

• construction of the Special Education and Rehabilitation Center in Jalapa, Veracruz;

• participation in productive agricultural and environmental sustainability projects in different locations in the municipal areas in the state of Tabasco;

• construction of residual water treatment plants in the municipality of Álamo Temapache in the state of Veracruz;

• reconditioning of the “Laguna del Carpintero” metropolitan park in the municipality of Tampico in the state of Tamaulipas;

• support for productive projects in the riverside fishing sector in the municipality of Carmen in the state of Campeche;

• extension of the support provided to the conservation program of the Sierra Lacandona, Chiapas and “Casa del Agua” areas in the Pantanos de Centla swamps in the state of Tabasco;

• support for school reconstruction and rehabilitation programs in several municipalities of the state of Veracruz;

• support for the construction of the Los Encinos and Arboledas highways in the municipality of Altamira in the state of Tamaulipas, as well as the repair of streets damaged by extreme rains and unexpected floods in the area; and

• construction of Reforma’s regional hospital, which will offer health care and specialty services in the municipality of Reforma, in the northern region of the state of Chiapas.

82

• We continued remediation work at the former refinery in Azcapotzalco to transform it into a recreational park. The second phase of this project began during the last quarter of 2008, and continued throughout 2009 with the remediation of 33 hectares in the areas located to the north of the former refinery in Azcapotzalco. This second phase of the remediation program included the activities of vapor extraction, bio-venting and bio-remediation, as well as air stripping, to remove volatile organic compounds in the groundwater. During October, November and December of 2009, the SEMARNAT confirmed remediation of 13.75 hectares to be complete, and allowed us to begin construction projects for the park on 10.97 hectares located in zone 5 of the former refinery site and 2.78 hectares located in zone 6 of the former refinery site. During December 2009, we requested from the SEMARNAT its confirmation of the conclusion of remediation of an additional area covering 16.40 hectares, and informed it of the continuing remediation of 2.85 hectares, due to concentrations of benzene being registered at levels above those permitted by the Comisión Federal para la Protección contra Riesgos Sanitarios (Federal Commission for Protection against Sanitary Risks) and the SEMARNAT.

In addition to the above, we have continued to implement other reforestation and environmental restoration activities, and to conduct environmental education and research in protected nature conservation areas.

Environmental Projects and Expenditures

In 2009, we spent approximately Ps. 5,643 million on environmental projects and related expenditures, as compared to Ps. 4,255 million in 2008. For 2010, we have budgeted Ps. 11,214 million for environmental projects and expenditures, including modernization of installations, implementation of systems and mechanisms to monitor and control atmospheric pollution, acquisition of equipment to address contingencies related to hydrocarbon spills, the expansion of water effluent systems, restoration and reforestation of affected areas, studies for environmental investigation and the conducting of environmental audits. In addition, we continue to conduct extensive research and development efforts to increase our capacity to produce gasoline, diesel and fuel oil with lower sulfur content.

We do not believe that the cost of complying with environmental laws or environmental requirements related to the North American Free Trade Agreement (NAFTA) among the governments of Mexico, the United States and Canada, the Vienna Convention for the Protection of the Ozone Layer, the Agreement on Environmental Cooperation between the Governments of Mexico and Canada or Mexico’s membership in the Organization for Economic Cooperation and Development, has caused or will cause a significant increase in our environmental expenditures.

83

TRADE REGULATION AND EXPORT AGREEMENTS

Although Mexico is not a member of OPEC, it has periodically announced increases and decreases in PEMEX’s crude oil exports in conjunction with production revisions by other oil producing countries, in order to stabilize oil prices. However, since 2004, PEMEX has not changed its export levels as a result of announcements by OPEC, and we believe that Mexico has no plans to change PEMEX’s current level of crude oil exports.

NAFTA did not affect the exclusive rights of Mexico, through Pemex-Exploration and Production, Pemex-Refining and Pemex-Gas and Basic Petrochemicals, to explore and exploit crude oil and natural gas in Mexico, to refine or process crude oil and natural gas or to produce basic petrochemicals in Mexico. Since 2003, non-basic petrochemical products enjoy a zero tariff under NAFTA and, subject to limited exceptions, exports of crude oil and petroleum products from Mexico to the United States and Canada are free or exempt from tariffs. Similarly, since 2003, imports of petroleum products from the United States and Canada to Mexico are free or exempt from tariffs. In addition, in 2004 NAFTA phased in lower tariffs on certain materials and equipment that we import into Mexico. The zero tariff on imports of non-basic petrochemicals from the United States and Canada to Mexico could, over time, increase competition in the non-basic petrochemicals industry in Mexico. To the extent that domestic and international prices for our products remain constant, lower tariffs on the products, materials and equipment that we import from and export to the United States and Canada will decrease our expenses and increase our income.

84

TAXES AND DUTIES

General

Taxes and duties applicable to PEMEX are a significant source of revenues to the Mexican Government. We contributed approximately 33.8% of the Mexican Government’s revenues in 2008 and 26.8% in 2009. In 2009, PEMEX paid a number of special hydrocarbon taxes and duties, in addition to the other taxes and duties paid by some of the subsidiary companies, as described below under “—Other Taxes.” Until 2006, the rates at which the Mexican Congress assessed hydrocarbon taxes and duties could vary from year to year and were set after taking into consideration our operating budget, our capital expenditure program and our financing needs. A new fiscal regime for Petróleos Mexicanos and the subsidiary entities, described below, became effective in 2006.

Fiscal Regime for PEMEX

The Mexican Congress approved a new fiscal regime for Petróleos Mexicanos and the subsidiary entities on November 10, 2005. The new fiscal regime went into effect on January 1, 2006, but was modified in 2007, with effect from January 1, 2008, in 2008, with effect from January 1, 2009, and again in 2009, with effect from January 1, 2010. Under the current fiscal regime, Pemex-Exploration and Production is governed by the Ley Federal de Derechos (Federal Duties Law), while the other subsidiary entities are governed by the Ley de Ingresos de la Federación (Federal Revenue Law) for the applicable fiscal year.

Effective January 1, 2009, the fiscal regime for Pemex-Exploration and Production consisted of the following duties:

Derecho Ordinario sobre Hidrocarburos (Ordinary Hydrocarbons Duty)	This duty is applied to the annual value of extracted production of crude oil and natural gas minus certain permitted deductions (including specific investments, certain costs and expenses, and the other duties referred to below, subject to certain conditions), and applies to all crude oil and natural gas extracted from fields other than those located in Paleocanal de Chicontepec and the deep waters in the Gulf of Mexico. The applicable rate for this duty was 73.5% in 2009, and will be 73.0% in 2010, 72.5% in 2011 and 71.5% in 2012 and thereafter. Deduction of costs must not exceed U.S. $6.50 per barrel of crude oil and U.S. $2.70 per thousand cubic feet of non-associated natural gas.
Derecho sobre la Extracción de Hidrocarburos (Extraction of Hydrocarbons Duty)	A floating annual rate is applied to the value of the crude oil and natural gas extracted from fields located in Paleocanal de Chicontepec and the deep waters in the Gulf of Mexico. The rate fluctuates between 10% and 20%, depending on the weighted average Mexican crude oil export price.
Derecho Especial sobre Hidrocarburos para Campos en el Paleocanal de Chicontepec (Special Hydrocarbons Duty for Paleocanal de Chicontepec Fields)	A 71.5% rate is applied annually to the value of crude oil and natural gas extracted from the Paleocanal de Chicontepec fields, minus certain permitted deductions (including specific investments, certain costs and expenses, and the other duties referred to below, subject to certain conditions).

85

Derecho Especial sobre Hidrocarburos para Campos en Aguas Profundas (Special Hydrocarbons Duty for Deep Water Fields)	A floating annual rate is applied to the value of the crude oil and natural gas extracted from fields located in the deep waters in the Gulf of Mexico, minus certain permitted deductions (including specific investments, certain costs and expenses, and the other duties referred to below, subject to certain conditions). The rate fluctuates between 60% and 71.5%, depending on the weighted average Mexican crude oil export price.
Derecho sobre Hidrocarburos para el Fondo de Estabilización (Hydrocarbons Duty for the Stabilization Fund)	Rates between 1% and 10% are applied to the value of the extracted crude oil production when the weighted average Mexican crude oil export price for a certain year exceeds between U.S. $22.00 and U.S. $31.00 per barrel.
Derecho para la Investigación Científica y Tecnológica en Materia de Energía (Duty for Scientific and Technological Research on Energy)	A rate of 0.30% of the value of extracted crude oil and natural gas production applied in 2009. This rate increased to 0.40% in 2010, and will increase further to 0.50% in 2011 and 0.65% in 2012 and thereafter.
Derecho para la Fiscalización Petrolera (Duty for Oil Monitoring)	A rate of 0.003% is applied to the value of extracted production of crude oil and natural gas for the year.
Derecho Extraordinario sobre la Exportación de Petróleo Crudo (Extraordinary Duty on Crude Oil Exports)	A rate of 13.1% is applied to the value resulting from the multiplication of (i) the difference between the annual weighted average Mexican crude oil export price and the budgeted crude oil price, times (ii) the annual export volume. The budgeted crude oil price for 2009 was U.S. $70.00 per barrel and for 2010 is U.S. $59.00 per barrel.
Derecho Único sobre Hidrocarburos (Sole Hydrocarbons Duty)	A floating annual rate is applied to the value of the extracted crude oil and natural gas from abandoned fields or fields that are in the process of being abandoned. The rate fluctuates between 37% and 57%, depending on the weighted average Mexican crude oil export price.

The Federal Duties Law, for purposes of the duties mentioned above, defines the deep water fields as those located in waters with an average depth of 500 meters or greater, and the Paleocanal de Chicontepec fields as those located in the following areas: in the state of Veracruz, Castillo de Teayo, Coatzintla, Coyutla, Chicontepec, Espinal, Ixhuatlán de Madero, Temapache, Papantla, Poza Rica de Hidalgo, Tepetzintla, Tihuatlán and Ignacio de la Llave; and in the state of Puebla, Francisco Z. Mena, Pantepec and Venustiano Carranza.

On November 27, 2009, an amendment to the Federal Duties Law was published in the Official Gazette of the Federation in which the Special Hydrocarbons Duty for Paleocanal de Chicontepec Fields and the Special Hydrocarbons Duty for Deep Water Fields were replaced by a new “Special Hydrocarbons Duty,” the Extraction

86

of Hydrocarbons Duty was modified, and a new “Additional Duty on Hydrocarbons” was created. Effective January 1, 2010, the fiscal regime for Pemex-Exploration and Production’s production from fields located in the Paleocanal de Chicontepec and the deep waters in the Gulf of Mexico consisted of the following duties:

Derecho Especial sobre Hidrocarburos (Special Hydrocarbons Duty)	A rate ranging from 30% to 36% is applied to the value of extracted production of crude oil and natural gas for the year from the fields located in the Paleocanal de Chicontepec and the deep waters in the Gulf of Mexico minus certain permitted deductions (including specific investments, certain expenses and costs, among others, subject to certain conditions).
Derecho sobre la Extracción de Hidrocarburos (Extraction of Hydrocarbons Duty)	A rate of 15% is applied to the value of extracted production of crude oil and natural gas for the year from fields located in the Paleocanal de Chicontepec and the deep waters in the Gulf of Mexico.
Derecho Adicional sobre Hidrocarburos (Additional Duty on Hydrocarbons)	A rate of 52% is applied to the value resulting from the multiplication of (i) the difference between the annual Mexican crude oil export price corresponding to the field from which such crude oil is extracted, and U.S. $60.00, times (ii) the extracted volume for the relevant year. This duty is applied only to fields located in the Paleocanal de Chicontepec and the deep waters in the Gulf of Mexico, and only if the Mexican crude oil export price per barrel of the extracted crude oil is greater than U.S. $60.00.

As set forth below, some of the above duties paid by Pemex-Exploration and Production did not have an impact on our cash outflow, because they were either credited against other taxes and duties, or deducted from the tax base of other duties:

• the Extraordinary Duty on Crude Oil Exports is credited against the Hydrocarbons Duty for the Stabilization Fund;

• the Extraordinary Duty on Crude Oil Exports, the Duty for Scientific and Technological Research on Energy and the Duty for Oil Monitoring are deducted from the tax base of the Ordinary Hydrocarbons Duty and a portion of these duties is deducted from the tax base of the Special Hydrocarbons Duties, as applicable;

• the amount paid in respect of the Hydrocarbons Duty for the Stabilization Fund, after credit from the Extraordinary Duty on Crude Oil Exports, is deducted from the tax base of the Ordinary Hydrocarbons Duty: and

• since 2010, a portion of the Duty for Scientific and Technological Research on Energy, the Duty for Oil Monitoring and the Extraction of Hydrocarbons Duty is deducted from the tax base of the Special Hydrocarbons Duty.

As described above, varying crude oil price levels directly affect the level of certain taxes paid.

87

The fiscal regime for Petróleos Mexicanos and its subsidiary entities, with the exception of Pemex-Exploration and Production, consists of the following taxes and duties:

Impuesto a los Rendimientos Petroleros (Hydrocarbons Income Tax)

A tax rate of 30% is applied to net income, as determined in accordance with the Federal Revenue Law for the applicable fiscal year.

IEPS tax

The IEPS tax is an indirect tax on domestic sales of gasoline and diesel that Pemex-Refining collects on behalf of the Mexican Government. The IEPS tax on the sale of gasoline and diesel is equivalent to the difference between the international reference price of each product (adjusted by freight costs and quality factors) and the retail price of the product (not including value added tax, the retailers’ margin and freight costs). Thus, the Mexican Government ensures that we retain an amount reflecting the international prices (adjusted as described above) of these products, while the Mexican Government collects the difference between the international prices and the prices at which these products are sold in Mexico. Since 2005, as a result of the new rules to calculate this tax rate, some rates have been negative. The Federal Revenue Law for each of the Fiscal Years of 2006 to 2009 provided that the IEPS tax amounts resulting from applying negative rates could be credited against the IEPS tax liability, and, if in excess, could be credited against the value added tax. Any remaining amount could be credited against the Ordinary Hydrocarbons Duty. Negative IEPS taxes, if any, in 2010 may also be credited in accordance with the same rules.

In 2009, we paid total taxes and duties in the amount of Ps. 546.6 billion (50.2% of sales revenues), as compared to the Ps. 771.7 billion (58.1% of sales revenues) of taxes and duties that we paid in 2008, mainly due to a reduction in Mexican crude oil export prices in 2009.

No assurance can be given that our tax regime will not be changed in the future.

Other Taxes

Since 1994, our interest payments on our external debt have been subject to Mexican Government withholding taxes. Nevertheless, withholding taxes do not represent a substantial portion of our total tax liability.

We are subject to municipal and state taxes, such as real property and payroll taxes. However, because most of our facilities are located on federal property, which is not subject to municipal taxation, real property taxes are not a significant part of our overall taxes. Similarly, payroll taxes do not represent a substantial portion of our total tax liability.

Petróleos Mexicanos and the subsidiary entities are exempt from Mexican corporate income tax; however, some of our subsidiary companies are Mexican corporations and are subject to the tax regime applicable to all other Mexican corporations. Mexican companies pay the higher of the two tax rates described below: The first is a corporate income tax at a rate of 30% applied to revenues, less certain deductions. The second is the Impuesto Empresarial a Tasa Única (Flat Rate Business Tax), which replaced the asset tax at the beginning of 2008 and imposed a minimum tax equal to 17.0% of a corporation’s sales revenues (less certain deductions and certain investment expenditures) in 2009; the rate of this tax has increased to 17.5% in 2010 and thereafter.

In addition, we have a number of non-Mexican subsidiary companies that may be subject to taxation in the jurisdiction of their incorporation or operations. The aggregate taxes paid by the subsidiary companies were Ps. 3,402 million in 2007, Ps. 2,625 million in 2008 and Ps. 1,778 million in 2009.

UNITED MEXICAN STATES

The information in this section with regard to Mexico has been included due to Petróleos Mexicanos’ and the subsidiary entities’ relationship with the Mexican Government and has been reviewed by the SHCP.

Form of Government

The President is the chief of the executive branch of the Mexican Government. In accordance with Mexico’s electoral law, on September 5, 2006, the Tribunal Electoral del Poder Judicial de la Federación (the federal electoral court) officially validated the results of the presidential election held in Mexico on July 2, 2006 and declared Felipe de Jesús Calderón Hinojosa, a member of the PAN, elected President. Mr. Calderón took office as President of Mexico on December 1, 2006 and his term expires on November 30, 2012. The Political Constitution of the United Mexican States limits the President to one six-year term and does not allow reelection for any additional terms.

The Partido Revolucionario Institucional (Institutional Revolutionary Party, or PRI) was the dominant political party in Mexico for several decades. From 1929 to 1994, the PRI won all presidential elections, and from 1929 until July 1997, the PRI held a majority of the seats in both chambers of the Mexican Congress. Until 1989, the PRI also won all of the state gubernatorial elections. However, in July 2000, the candidate of the Alianza por el Cambio (Alliance for Change), a coalition of the PAN, the oldest opposition party in the country, and the Partido Verde Ecologista de México (Ecological Green Party of Mexico), won the presidential election.

Local elections for state governorships were held on July 5, 2009 in Campeche, Colima, Nuevo León, Querétaro, San Luis Potosí and Sonora. The PAN currently holds seven state governorships, the Partido de la Revolución Democrática (Democratic Revolution Party, or PRD) holds four state governorships and the governorship of the Federal District and the Coalición Por el Bien de Todos (Coalition for the Well-being of Everyone), an alliance formed by the PRD, the Labor Party and the Convergence for Democracy Party, holds one state governorship. The PRI holds the remaining 19 of the 31 state governorships. Local elections for state governorships will be held again in Mexico on July 4, 2010.

Legislative authority is vested in the Mexican Congress, which is composed of the Senate and the Chamber of Deputies. Senators serve a six-year term, deputies serve a three-year term and neither may serve consecutive terms in the same chamber. The Senate is composed of 128 members, 96 of whom are elected directly while the other 32 are elected through a system of proportional representation. The Chamber of Deputies is composed of 500 members, 300 of whom are elected directly by national electoral districts and 200 of whom are elected through a system of proportional representation that allocates those seats to political party representatives based on the proportion of the votes cast for those parties that receive at least 2.0% of the national vote. The Political Constitution of the United Mexican States provides that the President may veto bills and that the Mexican Congress may override such vetoes with a two-thirds majority vote of each chamber.

In the congressional election held on July 5, 2009, all of the seats in the Chamber of Deputies were up for election. The members of the Senate were elected on July 2, 2006. The following table provides the current distribution of congressional seats, reflecting certain post-election changes in the party affiliations of certain senators and deputies.

The Economy

Gross Domestic Product

According to preliminary figures, Mexico’s GDP grew by 1.5% in real terms during 2008, as compared to 2007. As a result of the adverse international economic environment and the deepening of the global financial crisis in the fourth quarter of 2008, economic activity in Mexico lost momentum during the year. During the first three quarters of 2008, economic growth slowed in response to the gradual deterioration of external demand, with real GDP growing by 2.4% through the end of the third quarter of 2008 as compared to the same period of 2007, and during the last quarter of the year, Mexico registered negative real GDP growth of 1.6% in annual terms. During 2008, the finance and insurance sector increased by 18.6%; the information sector increased by 8.0%; the real estate, rental and leasing sector increased by 3.2%; the professional, scientific and technical services sector increased by 3.1%; the wholesale and retail trade sector increased by 2.2%; the administrative support, waste management and remediation services sector increased by 1.6%; the education services sector increased by 1.6%; the arts, entertainment and recreation sector increased by 1.5%; the agriculture, forestry, fishing and hunting sector increased by 1.2%; the public administration sector increased by 1.2%; the accommodation and food services sector increased by 0.9%; the construction sector increased by 0.6%; the transportation and warehousing sector increased by 0.1% and the other services (except public administration) sector increased by 0.6%, each in real terms as compared to 2007.

According to preliminary figures, Mexico’s GDP decreased by 6.5% in real terms during 2009, as compared to 2008. Global economic activity began to recover beginning in the second half of 2009, after a deep contraction observed in the previous six months. The recovery was driven by fiscal and monetary stimulus programs implemented in many advanced economies and in some emerging market countries, as well as the several measures taken to stabilize the operation of the international financial system. During 2009, the public administration sector increased by 3.7%; the agriculture, forestry, fishing and hunting sector increased by 1.8%; the information sector increased by 1.6%; the utilities sector increased by 1.2% and the mining sector increased by 1.0%, each in real terms as compared to 2008. In contrast, the wholesale and retail trade sector decreased by 14.5%; the manufacturing sector decreased by 10.2%; the accommodation and food services sector decreased by 9.6%; the transportation and warehousing sector decreased by 8.1%; the construction sector decreased by 7.5%; the professional, scientific and technical services sector decreased by 5.7%; the administrative support, waste management and remediation services sector decreased by 5.4%; the real estate, rental and leasing sector

Inflation for 2009 was 3.6%, 3.0 percentage points lower than inflation in 2008, mainly due to the fall in demand resulting from the economic recession and lower food prices.

Inflation for the five months ended May 31, 2010 was 1.4%, 0.3 percentage points higher than during the same period of 2009.

2009 Monetary Program

Mexico’s monetary program for 2009 had as its principal objective the achievement of an inflation rate no higher than 3.0% (+/-1.0%) by the end of 2009. Mexico’s monetary program for 2009 was made up of the following elements:

• the announcement of an explicit, multi-year plan to control inflation;

• a systematic analysis of the economy and inflationary pressures;

• a description of the instruments used by Banco de México to achieve its objectives; and

• a policy of communication that promotes transparency, credibility and effective monetary policy.

During 2009, the M1 money supply increased by 5.1% in real terms, as compared with 2008. This increase was driven by higher amounts of bills and coins held by the public and checking account deposits. The amount of bills and coins held by the public at December 31, 2009 was 4.9% greater in real terms than at December 31, 2008, while the aggregate amount of checking account deposits denominated in pesos at December 31, 2009 was 1.4% greater in real terms than the amount of checking account deposits at December 31, 2008.

The Securities Market

The Mexican Stock Exchange is the only authorized stock exchange involved in the listing and trading of equity and debt securities in Mexico. Upon the consummation of the initial public offering of its shares on June 18, 2008, the Mexican Stock Exchange was transformed from a sociedad anónima de capital variable (private company) to a sociedad anónima bursátil de capital variable (public company). In connection with the initial public offering of shares, certain of the former stockholders of the Mexican Stock Exchange (banks and brokerage houses) created a control trust into which they deposited more than 50% of the issued and outstanding shares of the Mexican Stock Exchange, for purposes of voting such shares in the future as a single block. Both debt and equity securities are listed and traded on the Mexican Stock Exchange, including stocks and bonds of private sector corporations, equity certificates or shares issued by banks, commercial paper, bankers’ acceptances, certificates of deposit, Mexican Government debt and special hedging instruments linked to the dollar. Currently, institutional investors are the most active participants in the Mexican Stock Exchange, although retail investors also play a role in the market. The Mexican equity market is one of Latin America’s largest in terms of market capitalization, but it remains relatively small and illiquid compared to major world markets.

At December 31, 2009, the Mexican Stock Market Index stood at 32,120.5 points, representing a 43.5% nominal increase from the level at December 31, 2008. At June 15, 2010, the Mexican Stock Market Index stood at 32,685.4 points, representing a 1.8% increase from the level at December 31, 2009.

The renewal of the IMF contingent credit line was requested due to continued uncertainties related to global economic conditions and credit availability. On March 25, 2010, the IMF approved a one-year renewal of the contingent credit line. To date, no amounts have been disbursed under the contingent credit line.

On October 8, 2008, Banco de México announced a new policy under which it would conduct an auction of U.S. $400 million on any day during which the depreciation of the peso exceeded 2%, as compared to the previous day’s exchange rate. On March 5, 2009, Banco de México announced that it was reducing the value of these auctions to U.S. $300 million. In addition, Banco de México announced that beginning on March 9, 2009, it would auction U.S. $100 million each day through additional auctions. These additional auctions would be conducted by Banco de México irrespective of whether the peso had depreciated as compared to the previous day’s exchange rate. On May 29, 2009, Banco de México announced that the value of the depreciation-contingent auctions would be reduced to U.S. $250 million each day and that, beginning on June 9, 2009, the value of the daily additional auctions would be reduced to U.S. $50 million. On September 1, 2009, Banco de México announced that the daily additional auctions would be suspended as from October 1, 2009; however, the

95

depreciation-contingent auctions remained unchanged. On April 8, 2010, Banco de México announced that it was suspending the depreciation-contigent auctions as from April 12, 2010. From October 9, 2008 through September 30, 2009, Mexico sold an aggregate of U.S. $10.3 billion through the special daily auctions. From October 9, 2008 through April 9, 2010, Mexico sold an aggregate of U.S. $8.3 billion through the depreciation-contingent auctions.

On February 22, 2010, the Exchange Commission announced that it would conduct auctions of options, which would allow the holder of the option to sell U.S. dollars to Banco de México. This system is designed to allow Mexico to gradually accumulate international reserves without affecting the exchange rate.

Pursuant to the new auction policy and commencing in February 2010, Banco de México began conducting an auction on the last business day of each month, in which participating financial institutions can purchase options to sell U.S. dollars to Banco de México. These options remain exercisable on any day of the month immediately following the auction. The holders of these options are able to sell U.S. dollars to Banco de México at the tipo de cambio interbancario de referencia (reference interbank exchange rate, or FIX) as determined by Banco de México on the business day immediately prior to the exercise of the option, so long as the applicable rate does not exceed the observed average of the FIX over the 20 business days preceding the exercise date. The amount of options available for auction each month is U.S. $600 million. From February 25, 2010 through June 15, 2010, Banco de México auctioned an aggregate of U.S.$2.4 billion in options through this mechanism and through June 15, 2010, Banco de México had purchased an aggregate of U.S. $1.6 billion pursuant to the exercise of these options by their holders.

Exchange Controls and Foreign Exchange Rates

Since December 22, 1994, the Mexican Government has maintained a floating exchange rate policy, with Banco de México intervening in the foreign exchange market from time to time to minimize volatility and ensure an orderly market, as described under “—Balance of International Payments” above. The Mexican Government has also promoted market-based mechanisms for stabilizing the exchange rate, such as over-the-counter forward and options contracts between banks and their clients in Mexico, and authorization of peso futures trading on the Chicago Mercantile Exchange. In addition, since October 1996, Banco de México has permitted foreign financial institutions to open peso-denominated accounts and to borrow and lend pesos (subject to general restrictions on conducting banking activities in Mexico).

The peso/dollar exchange rate closed at Ps. 13.0659 = U.S. $1.00 on December 31, 2009, a 5.9% appreciation in dollar terms from the rate at the end of 2008. During 2009, the monthly average peso/dollar exchange rate was Ps. 13.5076 = U.S. $1.00. The peso/dollar exchange rate announced by Banco de México on June 16, 2010 (to take effect on the second business day thereafter) was Ps. 12.5878 = U.S. $1.00.

Public Finance

Fiscal Policy

The rationalization of public expenditure and the augmentation of revenue have been important components of the Mexican Government’s economic stabilization strategy, which has two fundamental objectives: (1) a reduction in poverty and (2) an increase in the rate of economic growth and employment.

The Mexican Government’s principal fiscal policy objectives in order to promote economic growth and employment opportunity are to:

• reduce the costs and risks associated with investment in Mexico;

• improve the ability of Mexican businesses to compete in global markets; and

• reduce the costs of goods and services to the consumer.

To achieve these objectives, the Mexican Government plans to:

• strengthen the rule of law and improve public security;

• simplify the administration of the tax system and facilitate the consistent application of tax law;

• improve the efficiency of the public sector through increased coordination among government entities and increased transparency of public spending, in order to permit increased spending on social development and infrastructure;

• further develop the Mexican equity and debt markets;

• improve the pension system for public sector workers;

• consolidate macroeconomic stability through fiscal discipline and the effective use of petroleum resources as well as the utilization of transparent and efficient budgetary procedures;

• improve the regulation (or pursue deregulation) of various sectors of the economy, as appropriate; and

• continue trade liberalization policies.

The Programa Nacional de Financiamiento al Desarrollo 2008-2012 (National Program to Finance Development 2008-2012, or PRONAFIDE), announced on May 27, 2008, established Mexican Government fiscal policy goals that include increased spending on social and economic development and greater investment in infrastructure, while maintaining a stable and responsible approach to public finances. To meet these policy objectives, the PRONAFIDE has outlined the following specific objectives:

• to strengthen the framework of fiscal responsibility to ensure a responsible and efficient fiscal policy, including a balanced budget and a prudent management of debt, each of which are core components of the development strategy, with the goals of reducing the historical balance of the public sector’s borrowing requirements and strengthening the mechanisms to carry out counter-cyclical policies;

• to continue to simplify the Mexican taxation system, seeking additional mechanisms to facilitate compliance with tax obligations and reduce tax evasion, in order to improve tax collection;

• to ensure the proper implementation of public finance reforms, in particular the Flat Rate Business Tax, in order to increase non-oil tax revenues and reduce the volatility of total government revenues;

• to improve the allocation and use of expenditures by evaluating their results, based on greater transparency and accountability, including the implementation of an expenditure programs evaluation system, integrating the Mexican Government’s accounting systems at all three levels of government and giving priority in the allocation of expenditures to sectors and programs that produce better results; and

97

• to promote the development of local financial markets and achieve savings in the financial costs of the public sector through the active management of public debt, while maintaining a level of risk consistent with the natural evolution of public finances and the development of local financial markets.

2009 Budget and Fiscal Results

During 2009, the Mexican Government’s public finance policy was aimed at creating conditions contributing to economic recovery, by increasing infrantructure investment and strengthening public security, while at the same time addressing the basic needs of the population, in accordance with the availability of resources and consistent with the budget approved by Congress. Due to the decrease in oil and non-oil revenues in 2009 resulting from the global financial and economic crisis, the Mexican Government implemented Ps. 90.7 billion in expenditure reductions.

According to preliminary figures, during 2009, the public sector overall balance registered a deficit of Ps. 274.5 billion, equivalent to approximately 2.3% of GDP. The public sector deficit exceeded the deficit approved in the 2009 budget by Ps. 47.0 billion, due to (i) an increase of Ps. 23.6 billion in physical investments by PEMEX, as a result of the depreciation of the exchange rate and (ii) an additional public deficit, excluding physical investments by PEMEX, of Ps. 23.4 billion, corresponding to 0.2% of GDP. Excluding physical investment by PEMEX, the public sector registered a deficit of Ps. 23.4 billion in 2009, as compared with a surplus of Ps. 62.1 billion in 2008.

According to preliminary figures, during 2009, the public sector primary balance, defined as total public sector revenues less expenditures other than interest payments on public debt registered a deficit of Ps. 10.6 billion, as compared to a surplus of Ps. 216.5 billion recorded in 2008. This was mainly due to the elimination of the PIDIREGAS program, so that investment expenditures by budgetary entities are now recognized when incurred.

According to preliminary figures, during 2009, public sector budgetary revenues decreased by 6.5% in real terms as compared to 2008. Oil revenues decreased by 21.4% in real terms and non-oil tax revenues decreased by 11.5% in real terms. Non-tax revenues, excluding those from PEMEX, increased from approximately 5.2% of total public sector budgetary revenues during 2008 to approximately 13.6% at the end of 2009. Non-tax revenues, excluding those from PEMEX, increased by 142.3% in real terms, due to revenues from the Mexican Government’s oil price hedge, the use of resources from the Oil Revenues Stabilization Fund and the Fund to Support Pension Restructuring and an increase in profits from the operations of Banco de México. Oil prices decreased by 31.9% in 2009, from an average price of U.S. $84.35 per barrel in 2008 to U.S. $57.44 per barrel in 2009, while PEMEX’s non-tax revenues as a percentage of total public sector budgetary revenues increased from approximately 12.7% in 2008 to approximately 13.5% in 2009.

According to preliminary figures, during 2009, public sector budgetary expenditures increased by 2.2% in real terms as compared to public sector budgetary expenditures during 2008. In 2009, public sector financing costs increased by 10.0% in real terms as compared to 2008.

At December 31, 2009, the balance of the Oil Revenues Stabilization Fund totaled Ps. 25.2 billion, the balance of the Federal Entities Revenue Stabilization Fund totaled Ps. 6.2 billion, the balance of the Fund for the Stabilization of Investment in the Infrastructure of Petróleos Mexicanos totaled Ps. 30.6 billion and the balance of the Fund to Support Pension Restructuring totaled Ps. 58.2 billion.

2010 Budget and Fiscal Package

On September 8, 2009, the Federal Executive Office submitted to the Mexican Congress the proposal for the Federal Annual Revenue Law for 2010 and the Federal Expenditure Decree for 2010.

98

On November 5, 2009, the Federal Annual Revenue Law for 2010 was published in the Official Gazette of the Federation and became effective on January 1, 2010. On November 17, 2009, the Federal Expenditure Decree for 2010 (together with the Federal Annual Revenue Law for 2010, the 2010 Budget) was published in the Official Gazette of the Federation and became effective on January 1, 2010.

The 2010 Budget contemplates an overall public sector budget deficit (excluding PEMEX’s physical investment) of Ps. 90 billion (0.7% of GDP). The total public sector deficit approved (including PEMEX’s physical investment) is equivalent to 2.8% of GDP.

The 2010 Revenue Law approved by the Mexican Congress anticipates public sector budgetary revenues totaling Ps. 2,797 billion and public expenditures totaling Ps. 2,887 billion. The measures approved by the Mexican Congress are expected to result in an estimated increase in non-oil revenues in the amount of Ps. 136.4 billion, or 1.1% of GDP.

The 2010 Budget will permit the Mexican Government to increase education expenditures by 2.5%, social security expenditures by 18.4%, social assistance expenditures by 17.0%, transportation and communications expenditures by 3.7% and sustainable development expenditures by 14.9%, each as compared with the 2009 budget.

The preliminary results for 2008 and 2009, as well as the budget assumptions and targets for the 2009 and 2010 budgets, are presented below.

(1) Preliminary. This note only applies to real GDP growth and figures expressed as a percentage of GDP, which are subject to periodic revision.

(2) 2009 budget figures represent budgetary estimates, based on the economic assumptions contained in the General Economic Policy Guidelines for 2009 published in November 2008 and in the Programa Económico 2009 (Economic Program 2009) published in November 2008, and do not reflect actual results for the year or the adverse global and domestic financial and economic environment in 2009.

(3) The Mexican Government entered into agreements to hedge oil prices in order to isolate the 2009 and 2010 budgets from the effect of reductions in the price of oil with respect to the level that was assumed in the Federal Revenue Law for each year. The annual average price guaranteed by these hedges was U.S. $70.00 in the fiscal year 2009 and U.S. $57.00 in the fiscal year 2010. Therefore, the approved expenditures level should not be affected if a lower Mexican oil mix price than the one assumed in each budget were observed. The total amount hedged in 2009 was 330 million barrels, which is the amount of net oil exports contemplated in the Economic Program 2009. The aggregate cost of hedging the oil revenues was U.S. $1.5 billion in 2009 and U.S. $1.2 billion in 2010.

According to preliminary figures, during the first quarter of 2010, the public sector overall balance registered a surplus of Ps. 11.3 billion, as compared with a deficit of Ps. 38.3 billion in the same period of 2009. Excluding physical investment by PEMEX, the public sector balance registered a surplus of Ps. 71.1 billion, Ps. 60.4 billion greater than the Ps. 10.7 billion surplus registered for the same period of 2009. The primary balance registered a surplus of Ps. 45.4 billion for the first quarter of 2010, as compared with the deficit of Ps. 234.7 million registered for the same period of 2009.

Public Debt

Internal Public Debt

Internal debt of the Mexican Government includes only the internal portion of indebtedness incurred directly by the Mexican Government, Banco de México’s general account balance (which was positive at December 31, 2009, indicating monies owed to the Mexican Government) and the assets of the Fondo del Sistema de Ahorro Para el Retiro (Retirement Savings System Fund). Net internal debt includes Cetes and other securities sold to the public in primary auctions, but does not include debt allocated to Banco de México for its use in regulating liquidity (Regulación Monetaria). See footnote 1 to the table “Internal Debt of the Mexican Government” below. Internal debt does not include the debt of the Instituto para la Protección al Ahorro Bancario (Bank Savings Protection Institute, or IPAB) or the debt of budget-controlled or administratively controlled agencies.

Over the last decade, the Mexican Government has pursued an internal debt strategy aimed at lengthening the average maturity of its debt in order to reduce its refinancing risk. To further this goal, the Mexican Government has in recent years introduced new instruments of longer maturities. In the last quarter of 1999, the Mexican Government offered for the first time 10-year securities denominated in Unidades de Inversión (UDIs) as well as 30-year UDI-indexed bonds, and subsequently began offering three-year, five-year, seven-year, ten-year, 20-year and 30-year fixed-rate peso-denominated bonds. Since the first quarter of 2008, twenty-year UDI-denominated bonds are no longer offered.

With the issuance of these securities, the Mexican Government has established a long-dated benchmark yield curve. The issuance of these instruments has also encouraged:

• increased use of long-term fixed rate contracts;

• the issuance of long-term peso-denominated securities by Mexican companies;

• the development of long-term financial hedging products; and

• the potential to direct long-term savings toward the financing of long-term investment projects.

According to preliminary figures, at December 31, 2009, the net internal debt of the Mexican Government totaled Ps. 2,471.3 billion, as compared to Ps. 2,332.7 billion of net internal debt at December 31, 2008. At December 31, 2009, the gross internal debt of the Mexican Government totaled Ps. 2,702.8 billion, as compared to Ps. 2,401.3 billion of gross internal debt at December 31, 2008. This total gross internal debt at December 31, 2009 was comprised of Ps. 388.6 billion of short-term debt and Ps. 2,314.2 billion of long-term debt, as compared to Ps. 281.3 billion of short-term debt and Ps. 2,120.1 billion of long-term debt at December 31, 2008.

100

The average maturity of the Mexican Government’s internal debt decreased by 0.02 years during 2009, from 6.36 years at December 31, 2008 to 6.34 years at December 31, 2009. The Mexican Government’s financing costs on internal debt totaled Ps. 173.3 billion, or 1.5% of GDP, during 2009, an increase of 9.11%, or 0.2% of GDP, as compared to 2008.

According to preliminary figures, at December 31, 2009, the net internal debt of the public sector (including liabilities associated with the Ley del Instituto de Seguridad y Servicios Sociales de los Trabajadores del Estado) totaled Ps. 2,594.1 billion, as compared to Ps. 2,268.5 billion outstanding at December 31, 2008. At December 31, 2009, the gross internal debt of the public sector totaled Ps. 2,887.9 billion, as compared to Ps. 2,498.7 billion outstanding at December 31, 2008. For purposes of this “Public Debt” section, public sector debt consists of the long-term indebtedness incurred directly by the Mexican Government, the long-term indebtedness incurred by budget-controlled agencies, the long-term indebtedness incurred directly or guaranteed by administratively controlled agencies (including, but not limited to, national development banks) and the short-term debt of the public sector. It does not include private sector debt guaranteed by the Mexican Government, unless and until the Mexican Government is called upon to make payment under its guaranty. Also for purposes of this “Public Debt” section, long-term debt is defined as all debt with maturities of one year or more from the date of issue, while short-term debt is defined as all debt with maturities of less than one year from the date of issue.

According to preliminary figures, at March 31, 2010, the net internal debt of the Mexican Government totaled Ps. 2,497.3 billion, as compared to the Ps. 2,471.3 billion outstanding at December 31, 2009. At March 31, 2010, according to preliminary figures, the gross internal debt of the Mexican Government totaled Ps. 2,841.4 billion, as compared to Ps. 2,702.8 billion at December 31, 2009.

At March 31, 2010, the gross internal debt of the public sector including PIDIREGAS recognition totaled Ps. 3,018.6 billion, as compared to Ps. 2,887.9 billion outstanding at December 31, 2009. The Mexican Government financing costs on internal debt totaled Ps. 12.5 billion for the first quarter of 2010, a 17.2% decrease in nominal terms, as compared to the same period of 2009.

(1) Internal debt figures do not include securities sold by Banco de México in open-market operations pursuant to Regulación Monetaria, which amounted to approximately Ps. 1.2 billion at March 31, 2010. Regulación Monetaria does not increase the Mexican Government’s overall level of internal debt, because Banco de México must reimburse the Mexican Government for any allocated debt that Banco de México sells into the secondary market and that is presented to the Mexican Government for payment. If Banco de México undertakes extensive sales of allocated debt in the secondary market, however, Regulación Monetaria can result in a situation in which the level of outstanding internal debt is higher than the Mexican Government’s figure for net internal debt.

External Public Debt

The total external debt of the public sector consists of the external portion of the long-term indebtedness incurred directly by the Mexican Government, the external long-term indebtedness incurred by budget-controlled agencies, the external long-term indebtedness incurred directly or guaranteed by administratively controlled agencies (including but not limited to national development banks) and the short-term external debt of the public sector. Private sector debt guaranteed by the Mexican Government is not included, unless and until the Mexican Government is called upon to make payment under the applicable guaranty. External public debt does not include, among other things, repurchase obligations of Banco de México with the IMF or the debt of the IPAB. For purposes hereof, long-term debt includes all debt with maturities of one year or more from the date of issue.

According to preliminary figures, at December 31, 2009, outstanding public sector gross external debt equaled U.S. $96.4 billion, an increase of approximately U.S. $39.4 billion from U.S. $56.9 billion at December 31, 2008, primarily due to the recognition as public sector debt of certain PIDIREGAS obligations, which were previously treated as off-balance sheet liabilities. Of this amount, U.S. $94.6 billion represented long-term debt while U.S. $1.8 billion represented short-term debt. Public sector external debt financing costs totaled U.S. $5.2 billion in 2009, a 16.0% decrease in nominal terms, as compared to 2008.

According to preliminary figures, at December 31, 2009, commercial banks held approximately 18.5% of Mexico’s total public sector external debt, multilateral and bilateral creditors (excluding the IMF) held approximately 20.0%, bondholders held approximately 60.7% and other creditors held the remaining 0.9%.

102

According to preliminary figures, total public debt (gross external debt plus net internal debt) at December 31, 2009 represented approximately 30.8% of nominal GDP, an increase of 5.7 percentage points as compared to December 31, 2008.

According to preliminary figures, outstanding public sector gross external debt increased by approximately U.S. $0.4 billion during the first quarter of 2010, from U.S. $96.4 billion at December 31, 2009, to U.S. $96.8 billion at March 31, 2010. Of this amount, U.S. $94.9 billion represented long-term debt and U.S. $1.9 billion represented short-term debt.

Our income is affected by a number of factors, including:

• changes in international prices of crude oil, refined petroleum products and petrochemical products, which are denominated in U.S. dollars, and domestic prices of petroleum products, which are denominated in pesos;

• the type and volume of crude oil produced and exported;

• the type and volume of natural gas produced, processed and sold;

• the results of development and exploration activities;

• the amount of taxes and duties that the Mexican Government imposes on us;

• fluctuations in the peso-U.S. dollar exchange rate; and

• Mexican and global economic conditions, including the levels of international interest rates.

Overview

Pursuant to the 2008 energy reform, PEMEX has been given the mandate to maximize the value that it creates through the activities of a productive nature with which it has been entrusted. We are fulfilling this mandate in the short term by increasing the profitability of our business lines through:

• an improved corporate governance structure, which will operate in accordance with the oil and gas industry’s best practices;

• new contracting mechanisms, which we expect to be able to implement in the near future; and

• the issuance of Citizen Bonds, which will serve both to further capitalize PEMEX and to increase our accountability.

105

In the medium term, changes in our operations are necessary to achieve results that show tangible improvements in efficiency and profitability. These changes must include:

• increased discipline in conducting our operations;

• incorporation of new technologies to efficiently develop our fields;

• enhanced project management;

• improved decision-making processes to shorten lengths of the time between discovery and production;

• increased administrative efficiency to reduce costs; and

• enhanced procurement processes.

We have reported significant losses in recent years. In 2008, we reported a net loss of Ps. 112.1 billion, primarily due to foreign exchange losses that we registered as a result of the depreciation of the Mexican peso in relation to the U.S. dollar during the fourth quarter of the year, the variation in inventories due the reduction in export crude oil prices and greater cost associated with the reserve for labor obligations, which increased due to the modification of FRS D-3 “Employee Benefits” (which we refer to as FRS D-3). In 2009, we reported a net loss of Ps. 94.7 billion as compared to a net loss of Ps. 112.1 in 2008, primarily due to reduced purchases of imported products and a benefit from the comprehensive financing result of Ps. 92.2 billion resulting from foreign exchange gains. PEMEX continued to report losses during 2009 mainly as a result of the high taxes and duties that we pay to the Mexican Government. We cannot predict whether we will report income or a loss for the 2010 fiscal year.

In 2008, our equity decreased by Ps. 23.0 billion, from Ps. 49.9 billion as of December 31, 2007, to Ps. 26.9 billion as of December 31, 2008. This decrease was primarily due to our net loss for the year of Ps. 112.1 billion, which was only partially offset by payments totaling Ps. 35.5 billion to PEMEX from the FEIIP and the FIEX, as well as the cancellation of the effect in equity of labor obligations in an amount of Ps. 51.8 billion. In 2009, PEMEX’s equity decreased by Ps. 93.7 billion, from Ps. 26.9 billion as of December 31, 2008 to negative Ps. 66.8 billion as of December 31, 2009. This decrease was primarily due to the net losses recorded in 2009 and previous years. We note that under the Ley de Concursos Mercantiles (Commercial Bankruptcy Law of Mexico), decentralized public entities such as Petróleos Mexicanos and the subsidiary entities cannot be subject to a bankruptcy proceeding. In addition, our current financing agreements do not include financial covenants or events of default that would be triggered as a result of our having negative equity. See “—Liquidity and Capital Resources” below.

Critical Accounting Policies

Some of our accounting policies require the application of judgment by management in selecting the appropriate assumptions for calculating financial estimates. By their nature, these judgments are subject to a degree of uncertainty and are based on: our historical experience; terms of existing contracts; management’s view of trends in the oil and gas industry, both internationally and within Mexico; economic factors in Mexico; and information from outside sources. We believe that the following critical accounting policies, among others, affect management’s judgments and estimates used in the preparation of our consolidated financial statements, and could potentially impact our financial results and future financial performance.

Successful Efforts Method of Oil and Gas Accounting

We apply the successful efforts method of oil and gas accounting. This accounting principle requires that development costs, including the costs of drilling exploratory wells and exploratory-type stratigraphic test wells, are initially capitalized and, if proved reserves are not discovered, the capitalized costs are later charged to expenses. The capitalized costs of wells and related equipment are amortized over proved developed reserves, as the related oil and gas reserves are extracted. Our reserves estimates are determined in accordance with earth science and petroleum engineering principles and practices pursuant to Rule 4-10(a), and can vary as a result of changes in such factors as forecasted oil and gas prices, reservoir performance and oil field technology.

Downward revision of our reserves estimates can result in: (a) higher depreciation and depletion expense per barrel in future periods; (b) an immediate write-down of an asset’s book value in accordance with accounting

106

rules for the impairment of properties; or (c) changes in our accrual of the asset retirement obligation. An impairment of oil and gas producing fixed assets will result if the downward revisions are so significant that the estimated future cash flows from the remaining reserves in the field are insufficient to recover the unamortized capitalized costs. Conversely, if the oil and gas reserves quantities are revised upward, our per barrel depreciation and depletion expense will be lower.

The application of successful efforts accounting can also cause material fluctuations between periods in exploration expense if drilling results are different than expected or if we change our exploration and development plans. The determination that exploratory drilling was unsuccessful in finding economically producible reserves requires the immediate expensing of previously capitalized drilling costs. We make semi-annual assessments of the amounts included within fixed assets to determine whether capitalization is initially appropriate and should continue. Exploration wells capitalized beyond 12 months are subject to additional judgment as to whether the facts and circumstances have changed, and therefore whether the conditions described in clauses (a) and (b) below no longer apply. Exploration wells more than 12 months old are expensed unless: (a) (i) they are in an area requiring major capital expenditures before production can begin, (ii) commercially productive quantities of reserves have been found, and (iii) they are subject to further exploration or appraisal activity, in that either drilling of additional exploratory wells is under way or firmly planned for the near future; or (b) proved reserves are recorded within 12 months following the completion of exploratory drilling.

Environmental Remediation, Asset Retirement Obligations

We also make judgments and estimates in recording liabilities for environmental cleanup and asset retirement obligations. Estimated liabilities for environmental remediation and asset retirement obligations are subject to change as a result of changes in laws, regulations and their interpretation, the review of additional information on the extent and nature of site contamination, the determination of additional works that need to be undertaken, improvements in technology, the nature and timing of expenditure, foreign currency exchange rates to the extent that some of these costs are incurred in U.S. dollars, and changes in discount rates. In addition, with respect to offshore properties, our historical dismantlement and plugging experiences have been very limited, and, therefore, our estimates of the expected cost or salvage value may vary from what will actually be incurred for many of these long-term properties when these activities are ultimately undertaken.

While we believe that our environmental remediation and asset retirement obligation provisions are adequate and that the interpretations of existing law we have applied are appropriate, the amounts estimated for future liabilities, which are based on discounted cash flows, may differ materially from the costs that will actually be incurred to remediate our properties. If we determine that an environmental remediation or asset retirement obligation provision is insufficient, it will be adjusted accordingly in the results of operations of the period in which the determination is made.

Employee Benefit Plans

We provide a range of benefits to our current and retired employees, including pensions, post-retirement health care benefits and post-employment benefits (primarily health services and supplemental payments). We annually record amounts relating to these plans based on calculations which include various actuarial assumptions, such as nominal discount rates, assumed rates of return, compensation increases, turnover rates and health care cost trend rates. We review our actuarial assumptions on an annual basis and modify them based on current rates and trends when it is deemed appropriate to do so. As required by Mexican FRS and U.S. GAAP, the effect of these modifications is generally recorded or amortized over future periods. We believe that the assumptions used in recording our obligations under our plans, which are presented in Notes 12 and 21 II(e) to our consolidated financial statements included herein, are reasonable based on our experience and on the advice of our independent actuaries.

Financial Instruments

Under Mexican FRS, effective January 1, 2005, we adopted the provisions of Bulletin C-10, “Derivative Financial Instruments and Hedging Operations” (which we refer to as Bulletin C-10), which provides expanded

107

guidance for the recognition, valuation, accounting treatment and disclosures applicable to derivative financial instruments including hedges and embedded derivatives. Bulletin C-10 requires that all financial instruments, with the exception of “held to maturity” investments, be recorded at fair value. Held to maturity investments are recorded at amortized cost subject to an impairment review.

We have calculated the fair value of these derivatives using common market valuation methods and value-influencing market data at the relevant respective balance sheet dates. We believe that the assumptions used in calculating the fair value of these instruments, which are presented in Notes 11 and 21 I(h) to our consolidated financial statements included herein, are appropriate based on our experience, applicable accounting standards and the available inputs.

Impairment of Long-Lived Assets

In addition to our oil and gas assets that could become impaired under the application of successful efforts accounting, other long-lived assets could become impaired and require write-down if circumstances warrant. Conditions that could cause our assets to become impaired include lower than forecasted commodity sales prices, changes in our business plans and plant modernizations, or a significant adverse change in the national or international business climate. The amount of an impairment charge would be based on estimates of an asset’s fair value compared with its book value. While we believe that our estimates of future cash flows are reasonable, different assumptions regarding projected commodity sales prices, production and overhead costs and foreign currency exchange rates and inflation could materially affect the anticipated cash flows to be generated by long-lived assets, thereby affecting the evaluations of the carrying values of those long-lived assets.

Accounting for Income Taxes

As described under “Item 4—Information on the Company—Taxes and Duties” above and in Note 19 to our consolidated financial statements included herein, a new fiscal regime applicable to Petróleos Mexicanos and the subsidiary entities became effective on January 1, 2006 and amendments to the fiscal regime applicable to Pemex-Exploration and Production became effective on January 1, 2008, January 1, 2009 and January 1, 2010. In addition, PMI and PMI Norteamérica, S.A. de C.V. are subject to the tax regime applicable to all other Mexican corporations. In general, Mexican companies are taxed based on pre-tax income at a statutory rate.

As a consequence of the tax regime applicable to Petróleos Mexicanos and its subsidiary entities, and in accordance with Mexican FRS, in the preparation of our consolidated financial statements, Petróleos Mexicanos and the subsidiary entities (except Pemex-Exploration and Production) are required to estimate taxable income and the period over which deferred tax assets will be recoverable. This process involves an estimation of our actual current tax and an assessment of temporary differences resulting from differing treatment of items for tax and accounting purposes. These differences result in deferred assets and liabilities, which are included within our consolidated balance sheet. We must then assess the likelihood that our deferred assets will be recovered from future taxable income and to the extent we believe that recovery is not likely, we must establish a valuation allowance. To the extent we establish a valuation allowance or increase this allowance in a period, we must include a charge against the tax provision in the statement of operations.

Management judgment is required in determining our provision for income taxes, our deferred tax assets and liabilities and any valuation allowance recorded against our net deferred tax asset. The valuation allowance is based on our estimates of taxable income and the period over which our deferred tax asset will be recoverable. In the event that actual results differ from these estimates or we adjust these estimates in future periods, we may need to establish an additional valuation allowance, which could materially impact our financial position and results of operations.

Contingencies

In the ordinary course of business, we are named in a number of lawsuits of various types. We evaluate the merit of each claim and assess the likely outcome. Liabilities for loss contingencies are recorded when an unfavorable decision is probable and the amount is reasonably estimable. When a reasonable estimation cannot be made, qualitative disclosure is provided in the notes to our consolidated financial statements. We do not recognize contingent revenues, earnings or assets until their realization is assured.

108

Inflation Accounting

In accordance with FRS B-10, effective January 1, 2008, we no longer use inflation accounting, unless the economic environment in which we operate qualifies as “inflationary,” as defined by Mexican FRS. Because the economic environment in the three-year periods ended December 31, 2008 and 2009 did not qualify as inflationary, we did not use inflation accounting to prepare our consolidated financial statements as of December 31, 2008 and 2009 included herein. As a result, unless otherwise indicated, all amounts included in “Item 5—Operating and Financial Review and Prospects” are presented in nominal terms; however, such amounts do reflect inflationary effects recognized up to December 31, 2007.

These policies are more fully described in Notes 3 and 21 to our consolidated financial statements included herein.

Sales Volumes and Prices

The profitability of our operations in any particular accounting period is directly related to the sales volume of, and average realized prices for, the crude oil and natural gas that we sell. These average realized prices for crude oil and natural gas fluctuate from one period to another due to world market conditions and other factors.

Export Volumes and Prices

Pemex-Exploration and Production sells crude oil to PMI, which then sells it to international clients. The volume of crude oil that we export is the volume delivered to international clients as adjusted for water content according to the bill of lading and standard market practice. PMI bases crude oil export price formulas on a basket of international reference prices and a constant set according to specific market conditions. We determine export prices of petroleum products and natural gas by reference to market conditions and direct negotiations with our clients.

Significant changes in international crude oil prices directly affect our financial results. The impact of changes in crude oil prices on our refining activities and petrochemicals business depends on:

• the magnitude of the change in crude oil prices;

• how quickly petroleum and petrochemical product prices in international markets adjust to reflect changes in crude oil prices; and

• the extent to which prices in Mexico, where we sell most of our petroleum products and petrochemicals, reflect international prices for those products.

The following table sets forth the weighted average price per barrel of crude oil that PMI received from exports and the average price of its benchmark, West Texas Intermediate crude oil, for the years indicated. Note that the average prices of West Texas Intermediate crude oil are higher than the average prices of crude oil that we export. This is primarily due to the higher cost of refining sour crude oils, which make up a majority of our exports. See “Item 4—Information on the Company—Business Overview—International Trading.”

Domestic Prices

The formulas used to determine prices for petroleum and petrochemical products sold in the Mexican market are determined by the SHCP and the Energy Regulatory Commission, in accordance with the Federal Public Administration Organic Law, the Ley de Planeación, the Reglamento Interior of the SHCP and the Energy Regulatory Commission Law. The SHCP and the Energy Regulatory Commission receive input from PEMEX and other governmental agencies through committees composed of officials of Petróleos Mexicanos, the subsidiary entities, some of the subsidiary companies, and representatives of various governmental agencies including, among others, the SHCP, the Ministry of Energy, the Secretaría de la Función Pública (Ministry of Public Function, which we refer to as the SFP), and the Ministry of Economy. The SHCP and the Energy Regulatory Commission determine wholesale and first-hand sale prices based on opportunity cost, which considers international prices, and makes adjustments to reflect transportation expenses and differences in the quality of our products relative to international benchmarks. The retail price is determined based on the wholesale price plus the value added tax, the retailer’s margin and freight costs. The SHCP adjusts prices for petroleum and petrochemical products sold in the Mexican market, so that they are consistent with the Mexican Government’s macroeconomic targets. See “Item 4—Information on the Company—Business Overview—Refining—Pricing Decrees” and “—Gas and Basic Petrochemicals—Pricing Decrees.”

The following table compares the average prices in nominal terms of petroleum products in Mexico and in the United States for the years indicated.

IEPS Tax, Hydrocarbon Duties and Other Taxes

The following table sets forth the taxes and duties that we recorded for each of the past three years.

	2007	2008	2009
	(in millions of pesos)(1)

Note: For a description of these taxes and duties, see “Item 4—Information on the Company—Taxes and Duties.”

Numbers may not total due to rounding.

(1) Figures for 2008 and 2009 are stated in nominal pesos.

(2) During 2007, 2008 and 2009, no IEPS tax was generated due to negative IEPS tax rates, as explained below.

Source: PEMEX’s audited financial statements.

The IEPS tax ensures that Pemex-Refining retains the portion of our sales revenues that represents the adjusted international reference prices of our products, and the Mexican Government receives the difference between the domestic retail prices, which are prices that are set by the Mexican Government based on target rates of inflation, and the adjusted international reference prices of diesel and gasoline.

Our retail prices for gasoline and diesel reflect the addition of the IEPS tax as described below, as well as the value added tax. We charge the IEPS tax only on gasoline and diesel.

For financial statement purposes, the IEPS tax, when due to the Mexican Government, is presented as part of net domestic sales and then deducted after “Income before hydrocarbon extraction duties.” From the end of 2005 through the end of 2009, the IEPS tax rate was negative, and therefore was not reflected as part of net domestic sales. In 2006, 2007, 2008 and 2009 (but not in 2005), we received a tax credit equal to the amount of negative IEPS taxes, which is reflected in our income statement under “other revenues.”

The SHCP determines retail prices of gasoline and diesel before the beginning of each fiscal year in conjunction with the preparation of the Mexican Government’s budget for that year.

For automotive fuels, the IEPS tax is equal to (a) the retail price at which gasoline and automotive diesel are sold to retailers, less (b) value-added tax, less (c) Pemex-Refining’s wholesale price, less (d) freight to gas stations and less (e) retailer’s margin.

111

When international prices increase, our wholesale price will increase and, as a result, the IEPS tax that we collect from consumers and transfer to the Mexican Government will decrease, since the retail prices of gasoline and diesel are fixed.

Since the end of 2005, the retail prices of gasoline and diesel have been less than the sum of Pemex-Refining’s wholesale price, the value-added tax, the freight to gas stations and the retailer’s margin, which has generated a “negative” IEPS tax rate. Beginning in 2006, the Federal Revenue Law established that PEMEX was permitted to credit negative IEPS taxes against its IEPS tax liability. Any remaining surplus could then be credited first toward its value added tax liability and then toward ordinary hydrocarbon duties. These IEPS tax credits are recorded in our income statement under “other revenues.” In 2009, we were permitted to credit Ps. 37.2 billion of negative IEPS tax, of which we credited Ps. 28.1 billion against our IEPS tax and value added tax liabilities. The remaining surplus was credited against the Ordinary Hydrocarbons Duty.

Relation to the Mexican Government

Petróleos Mexicanos and the subsidiary entities were created as decentralized public entities of the Mexican Government, rather than as Mexican corporations. Therefore, we do not have the power to issue shares of equity securities evidencing ownership interests and are not required, unlike Mexican corporations, to have multiple shareholders. The Mexican Government closely regulates and supervises our operations. However, our financing obligations do not constitute obligations of and are not guaranteed by the Mexican Government. Mexican Government secretaries control key executive decisions at PEMEX. The President of Mexico appoints six of the 15 members of the Board of Directors of Petróleos Mexicanos. The President of Mexico also appoints four professional members to the Board of Directors of Petróleos Mexicanos, whose appointments are ratified by the Senate. In addition, the SFP appoints the external auditors of the subsidiary entities.

The Mexican Government incorporates the annual budget and financing program of Petróleos Mexicanos and the subsidiary entities into its consolidated annual budget, which it submits to the Mexican Congress for approval.

Inflation

Mexico experienced high inflation during the 1980s. The annual rate of inflation (as measured by the change in the NCPI) decreased from a high of 159.2% in 1987 to 11.9% in 1992, 8.0% in 1993 and 7.1% in 1994. However, the economic events that followed the devaluation of the peso against the U.S. dollar in late 1994 and 1995, along with turbulence in international financial markets, caused inflation to increase to 52.0% in 1995. After 1995, inflation decreased to 27.7% in 1996 and 15.7% in 1997. The annual inflation rate was 3.3% in 2005, 4.1% in 2006, 3.8% in 2007, 6.5% in 2008 and 3.6% in 2009.

Mexican inflation has affected our consolidated financial statements in the following ways:

• Until December 31, 2007, we adjusted the value of certain of our fixed assets, materials and spare parts on our balance sheet to reflect the effects of inflation, using the NCPI in a comprehensive manner. This revaluation increased our assets in periods of high inflation. See Note 3(a) to our consolidated financial statements included herein. When we revalued fixed assets and inventories to reflect the effects of inflation, our subsequent depreciation and cost of sales charges increased, reducing our income. The higher carrying value further exposed us to subsequent impairment charges. See Note 3(i) to our consolidated financial statements included herein.

• Until December 31, 2007, Mexican FRS required that financial statements recognize the effects of inflation in accordance with Bulletin B-10. A component of inflation accounting which is not reflected in historical based accounting is the recognition of a gain or loss on monetary position, which is included in the income statement as a component of comprehensive financing cost. The gain or loss on monetary position captures the impact of purchasing power fluctuations on monetary assets and

112

liabilities. To the extent that we have had a net monetary liability position, the income statement reflected a monetary gain as measured by the change in the NCPI. To the extent that we have had a net monetary asset position, the income statement reflected a monetary loss as measured by the change in the NCPI.

Effective January 1, 2008, we adopted FRS B-10, which superseded Bulletin B-10 and its five amendments, as well as the related circulars and Interpretación de las Normas de Información Financiera (Interpretation of Financial Reporting Standards, or INIF) No. 2. The principal effects of FRS B-10 on our consolidated financial statements are:

• Recognition of the effects of inflation on the financial information until December 31, 2007, based on the NCPI, as reported by Banco de México. In 2008 and 2009, the effects of inflation were not recognized in our consolidated financial statements because the accumulated inflation over the three-year periods ended December 31, 2008 and 2009 was less than 26%, and the economic environment therefore did not qualify as “inflationary.”

• If at the end of a future year, the accumulated inflation over the most recent three-year period were to be equal to or higher than 26%, the economic environment would be considered “inflationary,” and we would therefore be required to retroactively recognize the effects of inflation not previously included in our consolidated financial statements while the economic environment was considered non-inflationary.

• The indexes used for the recognition of inflation in 2007, 2008 and 2009 were as follows.

December 31,	NCPI	Inflation

In addition, beginning in 2008, comparisons of financial results of different years are presented in nominal, not constant, terms.

The initial effects derived from the adoption of FRS B-10 included a Ps. 171.7 billion charge in the restatement of equity and a credit to results from prior years in the same amount. However, our income statement, assets, liabilities and the balance sheet were not otherwise affected.

Consolidation

Our financial statements consolidate the results of Petróleos Mexicanos, the subsidiary entities and the subsidiary companies. Certain non-material subsidiary companies are not consolidated and are accounted for under either the cost method or the equity method. For a list of the consolidated subsidiary companies, see Note 3(b) to our consolidated financial statements included herein.

Export Agreements

Even though Mexico is not a member of OPEC, in the past, following OPEC announcements of production cuts and increases of production, and in order to maintain oil market stability, Mexico has announced increases and decreases in Mexico’s crude oil exports in connection with increases or decreases of crude oil production by other oil producing countries. However, since 2004, PEMEX has not changed its export levels as a result of announcements by OPEC, and we believe that Mexico has no plans to change PEMEX’s current level of crude oil exports.

Results of Operations of Petróleos Mexicanos, the Subsidiary Entities and the Subsidiary Companies—For the Year Ended December 31, 2009 Compared to the Year Ended December 31, 2008

Sales

Total sales decreased by 18.0% in 2009, from Ps. 1,328.9 billion in 2008 to Ps. 1,089.9 billion in 2009. This decrease resulted primarily from lower crude oil prices and a lower volume of crude oil exports.

Domestic Sales

Domestic sales decreased by 12.3% in 2009, from Ps. 679.8 billion in 2008 to Ps. 596.4 billion in 2009, primarily due to decreases in the prices and volumes of sales of natural gas, petroleum products and petrochemicals sold by PEMEX. Domestic sales of natural gas decreased by 43.9% in 2009, from Ps. 106.8 billion in 2008 to Ps. 59.9 billion in 2009, as a result of a decrease in the price of natural gas, as well as a 16.5% decrease in the volume of sales of natural gas. Domestic sales of petroleum products decreased by 5.0% in 2009, from Ps. 540.7 billion in 2008 to Ps. 513.4 billion in 2009, primarily due to lower prices and a 3.0% decrease in the volume of domestic sales of petroleum products. The decrease in the sales volumes of petroleum products, from 1,827 thousand barrels per day in 2008 to 1,772 thousand barrels per day in 2009, was primarily due to lower demand attributable to the contraction of economic growth in Mexico. Domestic petrochemical sales (including sales of certain by-products of the petrochemical production process) decreased by 28.6%, from Ps. 32.2 billion in 2008 to Ps. 23.0 billion in 2009, due to decreases in the prices of most petrochemical products sold by PEMEX, which was only partially offset by a 0.3% increase in the volume of petrochemical product sales.

Export Sales

Export sales decreased by 24.2% in peso terms in 2009, from Ps. 644.4 billion in 2008 to Ps. 488.3 billion in 2009. Excluding the trading activities of the PMI Group (in order to show only the amount of export sales related to the subsidiary entities), export sales by the subsidiary entities to the PMI Group and third parties decreased by 24.1% in peso terms, from Ps. 536.0 billion in 2008 to Ps. 406.9 billion in 2009. In dollar terms, excluding the trading activities of the PMI Group, export sales (which are dollar-denominated) decreased by 38.8% in 2009, from U.S. $49.5 billion in 2008 to U.S. $30.3 billion in 2009. This decrease was the result of a decline in crude oil and product prices and a reduction in the volume of crude oil exports. The trading and export activities of the PMI Group generated additional marginal revenues of Ps. 81.4 billion in 2009, 24.9% less in peso terms than the Ps. 108.4 billion of additional revenues generated in 2008, mainly due to a decrease in average price of crude oil. The weighted average price per barrel of crude oil that the PMI Group sold to third parties in 2009 was U.S. $57.42, 31.9% less than the weighted average price of U.S. $84.38 in 2008.

Export crude oil sales by Pemex-Exploration and Production to PMI accounted for 84.5% of export sales (excluding the trading activities of the PMI Group) in 2009, as compared to 87.2% in 2008. These crude oil sales decreased in peso terms by 26.5% in 2009, from Ps. 467.6 billion in 2008 to Ps. 343.9 billion in 2009, and decreased in dollar terms by 40.9% in 2009, from U.S. $43.3 billion in 2008 to U.S. $25.6 billion in 2009. The weighted average price per barrel of crude oil that Pemex-Exploration and Production sold to PMI for export in 2009 was U.S. $57.44, 31.8% less than the weighted average price of U.S. $84.26 in 2008. The volume of crude oil exports decreased by 12.7%, from 1,403 thousand barrels per day in 2008 to 1,225 thousand barrels per day in 2009, mainly as a consequence of the decline in production of the Cantarell fields.

Export sales of petroleum products by Pemex-Refining and Pemex-Gas and Basic Petrochemicals to the PMI Group and third parties, including natural gas and natural gas liquids, as a percentage of export sales of petroleum products (excluding the trading activities of the PMI Group), increased from 12.1% of those export sales in 2008 to 15.2% of those export sales in 2009. Export sales of petroleum products, including natural gas and natural gas liquids, decreased by 5.4%, from Ps. 64.8 billion in 2008 to Ps. 61.3 billion in 2009, primarily due to lower prices of petroleum product exports. In dollar terms, export sales of petroleum products, including

114

natural gas and natural gas liquids, decreased by 22.0%, from U.S. $5.9 billion in 2008 to U.S. $4.6 billion in 2009. Export sales of natural gas decreased by 72.2%, from Ps. 3.6 billion in 2008 to Ps. 1.0 billion in 2009. This decrease was mainly due to a decline in natural gas prices and a decrease in natural gas production.

Petrochemical products accounted for the remainder of export sales in 2008 and 2009. Export sales of petrochemical products (including certain by-products of the petrochemical process) decreased by 52.8% in 2009, from Ps. 3.6 billion in 2008 to Ps. 1.7 billion in 2009, primarily due to a decrease in the volume of petrochemical product exports. In dollar terms, export sales of petrochemical products (including certain by-products of the petrochemical process) decreased by 61.1% in 2009, from U.S. $340.9 million in 2008 to U.S. $132.5 million in 2009.

Services Income

In 2008 and 2009, services income amounted to Ps. 4.8 billion and Ps. 5.3 billion, respectively. This 10.8% increase in 2009 was mainly due to increased fees charged by Pemex-Refining for freight services provided to third parties.

Costs of Sales and General Expenses

Costs of sales decreased by 14.2%, from Ps. 654.0 billion in 2008 to Ps. 561.1 billion in 2009. This decrease was mainly due to a reduction of Ps. 104.4 billion in purchases of imported products to then be sold in Mexico, which was only partially offset by an inventory variation of Ps. 10.2 billion, based on results of inventories valuation.

General expenses, which include transportation, distribution and administrative expenses, decreased by 3.2%, from Ps. 103.8 billion in 2008 to Ps. 100.5 billion in 2009. This reduction was primarily due to a decrease of Ps. 5.0 billion in the net cost for the year of employee benefits, which was partially offset by an increase of Ps. 2.3 billion in operating expenses.

Other Revenues (principally IEPS benefit), Net

Other revenues, net, decreased by 79.6% in 2009, from Ps. 198.0 billion in 2008 to Ps. 40.3 billion in 2009, primarily due to a decrease in revenues resulting from lower negative rates of the IEPS tax in 2009, as compared to 2008. As a result, PEMEX recognized revenues from IEPS tax credits of Ps. 194.6 billion in 2008 and Ps. 37.2 billion in 2009.

Comprehensive Financing Result

Under Mexican FRS, comprehensive financing result reflects interest income (including gains and losses on certain derivative instruments), interest expense and foreign exchange gain or loss. In 2009, our loss associated with comprehensive financing result decreased by 85.8%, from a loss of Ps. 107.5 billion in 2008 to a loss of Ps. 15.3 billion in 2009, as a result of the following.

Exchange Rate Gain/Loss. A substantial portion of PEMEX’s indebtedness, 80.5% at December 31, 2009, is denominated in foreign currencies. The appreciation of the peso therefore resulted in a foreign exchange gain of Ps. 14.7 billion in 2009, as compared to a loss of Ps. 71.1 billion in 2008. The peso/dollar exchange rate appreciated by 3.7% in dollar terms in 2009, from Ps. 13.5383 = U.S. $1.00 on December 31, 2008 to Ps. 13.0587 = U.S. $1.00 on December 31, 2009, as compared to a 24.6% depreciation of the exchange rate in 2008.

Interest, Net. PEMEX’s net interest expense decreased by Ps. 6.5 billion in 2009, primarily as a result of our net unrealized gains on DFIs treated as non-hedges. See Note 11(vii) to our consolidated financial statements included herein.

115

Taxes and Duties

Hydrocarbon extraction duties and other duties and taxes (including the IEPS tax) decreased by 29.2% in 2009, from Ps. 771.7 billion in 2008 to Ps. 546.6 billion in 2009, largely due to lower average crude oil prices and production volumes. In 2009, duties and taxes represented 50.2% of total sales, whereas in 2008 they represented 58.1% of total sales, because our effective rate of taxes and duties declines as oil prices fall.

Net Loss

In 2009, we had a net loss of Ps. 94.7 billion from Ps. 1,089.9 billion in total sales revenues, as compared to a net loss of Ps. 112.1 billion from Ps. 1,328.9 billion in total sales revenues in 2008. This decrease in net loss in 2009 resulted from the various factors described above.

Results of Operations of Petróleos Mexicanos, the Subsidiary Entities and the Subsidiary Companies—For the Year Ended December 31, 2008 Compared to the Year Ended December 31, 2007

Sales

Total sales increased by 16.6% in 2008, from Ps. 1,139.3 billion in 2007 to Ps. 1,328.9 billion in 2008. This increase resulted primarily from a 14.8% increase in domestic sales, from Ps. 592.0 billion in 2007 to Ps. 679.8 billion in 2008, due to increased unit prices and greater volumes of sales, mainly of petroleum products. In addition, total sales also increased due to an 18.7% increase in export sales, from Ps. 542.9 billion in 2007 to Ps. 644.4 billion in 2008, due to higher crude oil prices.

Domestic Sales

Domestic sales increased by 14.8% in 2008, from Ps. 592.0 billion in 2007 to Ps. 679.8 billion in 2008, due to increased prices and volumes of sales of principal petroleum and petrochemicals products. Domestic sales of petroleum products increased by 11.7% in 2008, from Ps. 484.1 billion in 2007 to Ps. 540.7 billion in 2008, primarily due to increases in the average sales prices of products sold in Mexico and a 0.6% increase in the sales volumes of petroleum products. The increase in the sales volumes of petroleum products, from 1,816 thousand barrels per day in 2007 to 1,827 thousand barrels per day in 2008, was primarily due to an increase in sales of gasoline and diesel. Domestic petrochemical sales (including sales of certain by-products of the petrochemical production process) increased by 25.8%, from Ps. 25.6 billion in 2007 to Ps. 32.2 billion in 2008, due to an increase in the domestic sales of some of the products manufactured by Pemex-Petrochemicals, such as polyethylenes and monoethylene glycol. Sales of natural gas increased by 29.8% in 2008, from Ps. 82.3 billion in 2007 to Ps. 106.8 billion in 2008, as a result of an increase in average prices.

Export Sales

Export sales increased by 18.7% in peso terms in 2008, from Ps. 542.9 billion in 2007 to Ps. 644.4 billion in 2008. Excluding the trading activities of the PMI Group (in order to show only the amount of export sales related to the subsidiary entities), export sales by the subsidiary entities to the PMI Group and third parties increased by 13.2% in peso terms, from Ps. 473.7 billion in 2007 to Ps. 536.0. In dollar terms, excluding the trading activities of the PMI Group, export sales (which are dollar-denominated) increased by 16.2% in 2008, from U.S. $42.6 billion in 2007 to U.S. $49.5 billion in 2008. This increase was mainly a result of increased crude oil and product prices. The trading and export activities of the PMI Group generated additional marginal revenues of Ps. 108.4 billion in 2008, 56.6% higher in peso terms than the Ps. 69.2 billion of additional revenues generated in 2007, mainly due to increased export prices of crude oil. The weighted average price per barrel of crude oil that the PMI Group sold to third parties in 2008 was U.S. $84.38, 36.9% higher than the weighted average price of U.S. $61.64 in 2007.

Export crude oil sales by Pemex-Exploration and Production to PMI accounted for 87.2% of export sales (excluding the trading activities of the PMI Group) in 2008, as compared to 89.0% in 2007. These crude oil sales

116

increased in peso terms by 10.9% in 2008, from Ps. 421.7 billion in 2007 to Ps. 467.6 billion in 2008, and increased in dollar terms by 14.2% in 2008, from U.S. $37.9 billion in 2007 to U.S. $43.3 billion in 2008. The weighted average price per barrel of crude oil that Pemex-Exploration and Production sold to PMI for export in 2008 was U.S. $84.26, 36.9% higher than the weighted average price of U.S. $61.57 in 2007. The volume of crude oil exports decreased by 16.8%, from 1,686 thousand barrels per day in 2007 to 1,403 thousand barrels per day in 2008, mainly as a consequence of the decline in production of the Cantarell fields and production shutdowns due to adverse weather conditions in the Gulf of Mexico.

Export sales of petroleum products by Pemex-Refining and Pemex-Gas and Basic Petrochemicals to the PMI Group and third parties, including natural gas and natural gas liquids, increased from 10.5% of export sales (excluding the trading activities of the PMI Group) in 2007 to 12.1% of those export sales in 2008. Export sales of petroleum products, including natural gas liquids, increased by 31.4%, from Ps. 49.3 billion in 2007 to Ps. 64.8 billion in 2008, primarily due to an increase in export prices of petroleum products. In dollar terms, export sales of petroleum products, including natural gas liquids, increased by 34.1%, from U.S. $4.4 billion in 2007 to U.S. $5.9 billion in 2008. Export sales of natural gas decreased by Ps. 0.5 billion, from Ps. 4.1 billion in 2007 to Ps. 3.6 billion in 2008. This decrease was mainly due to a decrease in natural gas production.

Petrochemical products accounted for the remainder of export sales in 2007 and 2008. Export sales of petrochemical products (including certain by-products of the petrochemical process) increased by 38.5% in 2008, from Ps. 2.6 billion in 2007 to Ps. 3.6 billion in 2008, primarily due to increased petrochemical product volume. In dollar terms, export sales of petrochemical products (including certain by-products of the petrochemical process) increased by 44.6% in 2008, from U.S. $235.6 million in 2007 to U.S. $340.7 million in 2008.

Services Income

In 2007 and 2008, services income amounted to Ps. 4.3 billion and Ps. 4.8 billion, respectively. This 11.6% increase in 2008 was mainly due to higher fees charged by Pemex-Refining for freight services provided to third parties.

Costs of Sales and General Expenses

Costs of sales, transportation, distribution expenses and administrative expenses increased by 38.9% in 2008, from Ps. 545.6 billion in 2007 to Ps. 757.8 billion in 2008. This increase was mainly due to higher product prices, greater product purchases, principally of petroleum products such as gasoline, diesel and liquefied gas, and an increase in the charges to net periodic cost of employee benefits, due to the effects of new amortization guidelines for the amortization of unrecognized/unamortized items under FRS D-3.

Due to existing price controls imposed by the Mexican Government on gasoline, diesel and LPG products sold in the domestic market, in 2008, we were not able to pass on all of the increases in the prices of our product purchases to our retail customers in Mexico.

Other Revenues (principally IEPS benefit), Net

Other revenues, net, increased by 148.1% in 2008, from Ps. 79.8 billion in 2007 to Ps. 198.0 billion in 2008, primarily due to an increase in revenues resulting from higher negative rates of the IEPS tax in 2008, as compared to 2007. As a result, PEMEX recognized revenues from IEPS tax credits of Ps. 72.1 billion and Ps. 194.6 billion in 2007 and 2008, respectively.

Comprehensive Financing Result

Under Mexican FRS, comprehensive financing result reflects interest income (including gains and losses on certain derivative instruments), interest expense and foreign exchange gain or loss. In 2008, our loss associated with comprehensive financing result increased by 437.5%, from a loss of Ps. 20.0 billion in 2007 to a loss of Ps. 107.5 billion in 2008, as a result of the following.

117

Exchange Rate Loss. A substantial portion of PEMEX’s indebtedness, 77.8% at December 31, 2008, is denominated in foreign currencies. The depreciation of the peso therefore resulted in a foreign exchange loss of Ps. 71.1 billion in 2008, as compared to a loss of Ps. 1.4 billion in 2007. The peso/dollar exchange rate depreciated by 19.7% in dollar terms in 2008, from Ps. 10.8662 = U.S. $1.00 on December 31, 2007 to Ps. 13.5383 = U.S. $1.00 on December 31, 2008, as compared to a 0.1% appreciation of the exchange rate in 2007.

Monetary Position Result. In accordance with FRS B-10, because the Mexican economy was not “inflationary” during the three-year period ended December 31, 2007, PEMEX did not recognize the effects of inflation in its 2008 financial results. As a result, PEMEX did not register a gain in monetary position in 2008, while in 2007 PEMEX registered a gain in monetary position of Ps. 12.9 billion.

Interest, Net. PEMEX’s net interest expense increased by Ps. 5.0 billion in 2008, primarily due to the net result of our derivative transactions. See Note 11(vii) to our consolidated financial statements included herein.

Taxes and Duties

Hydrocarbon extraction duties and other duties and taxes (including the IEPS tax) increased by 13.9% in 2008, from Ps. 677.3 billion in 2007 to Ps. 771.7 billion in 2008, largely due to the increase of the Hydrocarbons Extraction Duty, from Ps. 663.1 billion in 2007 to Ps. 761.2 billion in 2008. In 2008, duties and taxes represented 58.1% of total sales, whereas in 2007 they represented 59.4% of total sales, because our effective rate of taxes and duties rises as oil prices increase.

Net Loss

In 2008, we had a net loss of Ps. 112.1 billion from Ps. 1,328.9 billion in total sales revenues, as compared to a net loss of Ps. 18.3 billion from Ps. 1,139.3 billion in total sales revenues in 2007. This increase in net loss resulted from the various factors described above.

Liquidity and Capital Resources

Equity Structure and Certificates of Contribution “A”

Our total equity as of December 31, 2009 was Ps. (66.8 billion), and our total capitalization (long-term debt plus equity) amounted to Ps. 462.4 billion. Under the Commercial Bankruptcy Law of Mexico, decentralized public entities such as Petróleos Mexicanos and the subsidiary entities cannot be subject to a bankruptcy proceeding.

In March 1990, the Mexican Government exchanged U.S. $7.58 billion worth of external debt of Petróleos Mexicanos with international commercial banks for 30-year Collateralized Fixed Rate Bonds Due 2019 and Collateralized Floating Rate Bonds Due 2019 (also called Brady Bonds) issued by the Mexican Government. In exchange for the cancellation of this external debt, Petróleos Mexicanos’ indebtedness to the Mexican Government increased by an amount equal to U.S. $7.58 billion. The new indebtedness was denominated in currencies other than pesos. In December 1990, the Mexican Government and Petróleos Mexicanos agreed to capitalize the indebtedness incurred in March 1990 into Petróleos Mexicanos’ equity as Certificates of Contribution “A.” As a condition to this capitalization, Petróleos Mexicanos agreed to pay a minimum guaranteed dividend to the Mexican Government equal to the debt service on the capitalized debt at the exchange rates in effect at the date the payments were made. The total dividend on the Certificates of Contribution “A” was approved annually by the Board of Directors of Petróleos Mexicanos after the close of each fiscal year. In each quarter until January 2007, Petróleos Mexicanos made advance payments to the Mexican Government that totaled a prorated portion of the minimum guaranteed dividend. Following a payment of Ps. 4,270 million in January 2007, and because PEMEX’s obligation to pay minimum guaranteed dividends was fully performed in 2007, no further advance payments on the minimum guaranteed dividend are payable to the Mexican Government.

118

However, the Mexican Government may still require Petróleos Mexicanos to declare and pay dividends to it at any time.

From 2005 to 2009, Petróleos Mexicanos made advance payments and declared dividends to the Mexican Government as follows:

	Year Ended December 31,
	2005		2006		2007		2008		2009
	(in millions of pesos)(1)
Total advance payments to the Mexican Government	Ps.	16,501	Ps.	269	Ps.	4,270	Ps.	—	—
Dividends declared in respect of Certificates of Contribution “A”(2)		11,483		16,393		263		4,270	—

See “Item 3—Key Information—Selected Financial Data” for the inflation factors. Figures for 2008 and 2009 are stated in nominal pesos.

(2) In each of the four years ended December 31, 2008 the dividends were approved by the Board of Directors of Petróleos Mexicanos.

In December 2007, the Mexican Government made payments in the aggregate amount of Ps. 11,160 million to Petróleos Mexicanos, which it capitalized in equity. This total consisted of one payment in the amount of Ps. 11,132 million, derived from excess revenues that were paid in accordance with the Federal Law of Budget and Fiscal Accountability, article 19, fraction IV, clauses b) and c), and a payment of Ps. 19.7 million, which was received from the FIEX. During 2008, Petróleos Mexicanos also capitalized interest in the amount of Ps. 9.3 million related to these excess revenues payments.

In February 2008, the Mexican Government made another payment to Petróleos Mexicanos under the Federal Law of Budget and Fiscal Accountability, in the amount of Ps. 2,806.2 million. Petróleos Mexicanos capitalized this amount in equity. In December 2008, the Mexican Government made further payments in the aggregate amount of Ps. 32,639 million to Petróleos Mexicanos to fund infrastructure works, which were also capitalized in equity. In addition, Petróleos Mexicanos capitalized interest in the amount of Ps. 12.2 million related to these payments by the Mexican Government, for a total amount capitalized in 2008 of Ps. 35,457 million. In December 2009, Petróleos Mexicanos capitalized interest in the amount of Ps. 467.2 million.

Cash Flows from Operating, Financing and Investing Activities

During 2009, under Mexican FRS, net funds provided by operating activities were Ps. 173.1 billion, as compared to Ps. 34.2 billion in 2008. Net income before taxes and duties, determined on a cash flow basis, was Ps. 458.4 billion and items that did not require cash outlays totaled Ps. 187.2 billion in 2009, as compared to net income before taxes and duties of Ps. 536.3 billion and items that did not require cash outlays of Ps. 295.7 billion in 2008. Our net indebtedness increased by Ps. 55.3 billion in 2009, as compared to an increase of net indebtedness of Ps. 14.3 billion in 2008. Payments of pensions, seniority benefits and other post-retirement obligations totaled Ps. 24.5 billion in 2009, as compared to Ps. 22.0 billion in 2008. During 2009, we applied net funds of Ps. 215.0 billion for net investments at cost in fixed assets (Ps. 215.9 billion of new investments and capitalized comprehensive result, less Ps. 0.9 billion in dispositions of fixed assets), as compared to our application of net funds of Ps. 140.8 billion in 2008 for net investments at cost in fixed assets (Ps. 141.1 billion of new investments and capitalized comprehensive result, less Ps. 0.3 billion in dispositions of fixed assets).

At December 31, 2009, our cash and cash equivalents totaled Ps. 128.2 billion, as compared to Ps. 114.2 billion at December 31, 2008.

Investment Policies

Our Finance and Treasury Department requires that we maintain financial resources sufficient to meet our payment commitments and those of the subsidiary entities, as well as a comprehensive, consolidated cash position and related projections in anticipation of such commitments.

We also develop mechanisms for investment of our financial resources aimed at allowing us to take advantage of the most favorable market conditions and to access the most favorable service contracting conditions offered by financial institutions.

Investment of financial resources by our Finance and Treasury Department, in both pesos and dollars, is made in accordance with the following policies:

Investments of Financial Resources in Pesos

We are obligated, during the structuring and development phase of our financial transactions, to observe and comply with the applicable guidelines issued by the Mexican Government. These include the Lineamientos para el manejo de las disponibilidades de las entidades paraestatales del Gobierno Federal (Investment Guidelines for Public Sector Entities), as issued by the SHCP, and which provide that Petróleos Mexicanos may only invest in the following:

a) Mexican Government-issued securities;

b) financial transactions entered into with the Mexican Government;

c) demand deposits made in banking institutions, the balance of which should not exceed 10% of available financial resources (cash);

d) treasury deposits; and

e) representative shares of capital stock in mutual funds, whose investments are limited to Mexican Government securities.

In addition, repurchase agreements (which are sometimes called repo transactions) may only be entered into with financial institutions that maintain, at a minimum, the following credit ratings as issued by the applicable rating agency:

Domestic scale	Fitch Ratings	S&P	Moody’s
Long term	AA(mex)	MxAA	AA.mx

Investments of Financial Resources in Dollars

When transacting in dollars, it is our policy to invest in funds in which our resources are held for no more than 48 hours. Thereafter, such resources are deposited in dollar accounts held by Petróleos Mexicanos at Banco de México. All foreign exchange transactions, due to their volume, are performed with Banco de México.

The funds in which we invest must comply with PEMEX’s operational and strategic requirements, and have been previously approved by Banco de México on a case-by-case basis.

Currencies in which Cash and Temporary Investments are Maintained

We generally maintain cash and cash equivalents in pesos and in dollars, due to the revenues generated from both domestic and international sales of our products being denominated in these currencies. Similarly, we make payments of our various expenses, including those relating to our debt, in the same currencies.

Commitments for Capital Expenditures and Sources of Funding

Our current aggregate commitments for capital expenditures for 2010 total approximately Ps. 229.9 billion. For a general description of our current commitments for capital expenditures, see “Item 4—Information on the Company—History and Development—Capital Expenditures and Investments.”

In 2009, in nominal peso terms, Pemex-Exploration and Production invested a total of Ps. 180.5 billion in capital expenditures on exploration and production. In 2010, Pemex-Exploration and Production has 23 projects in its capital expenditures budget, for which Ps. 186.5 billion has been budgeted. For more detail on the expenditures for and purpose of these investments, see “Item 4—Information on the Company—Business Overview—Exploration and Production—Investment in Exploration and Production.”

Pemex-Refining invested in four infrastructure projects in 2009 and invested in other general operating projects, strategic planning, acquisition of equipment, research and development and complementary investments for a total of Ps. 18.5 billion in capital expenditures in nominal peso terms. In 2010, Pemex-Refining expects to invest Ps. 32.0 billion in capital expenditures. For more detail on the expenditures for and purpose of Pemex-Refining’s investments, see “Item 4—Information on the Company—Business Overview—Refining—Investments.”

Pemex-Gas and Basic Petrochemicals invests in projects primarily related to natural gas and condensates processing, transportation and storage. In 2010, Pemex-Gas and Basic Petrochemicals expects to invest Ps. 5.7 billion in capital expenditures, as compared to Ps. 3.9 billion of capital expenditures in 2009. For more detail on the expenditures for and purpose of Pemex-Gas and Basic Petrochemicals’ investments, see “Item 4—Information on the Company—Business Overview—Gas and Basic Petrochemicals—Investments.”

In 2010, Pemex-Petrochemicals expects to invest Ps. 4.8 billion in capital expenditures for six projects, as compared to Ps. 2.1 billion of capital expenditures in 2009. For more detail on the expenditures for and purpose of Pemex-Petrochemicals’ investments, see “Item 4—Information on the Company—Business Overview—Petrochemicals—Investments.”

Our current commitments for capital expenditures have increased in recent years as compared to previous years. Based on past experience, we expect to generate sufficient funds for our working capital, capital expenditures and investments through:

• cash flow generated by operations;

• the issuance of certificados bursátiles (peso-denominated publicly traded notes) in the Mexican market;

• the issuance of debt securities in the international capital markets;

• the renewal of existing lines of credit and the entering into of new lines of credit from international and local commercial banks; and

• other financing activities.

The securities that we issue may vary in tenor, amount, currency and type of interest rate. We may issue debt securities in U.S. dollars, Japanese yen, euros, pounds, pesos or Swiss francs, among others; these securities may be issued with fixed or floating rates and with maturities of one or more years including perpetual debt securities, depending on market conditions and funding requirements. We may issue securities in the international capital markets or in the Mexican domestic market, or in both markets. Commercial bank syndicated loans may be established with single or multiple tranches with varying maturities. Bilateral loans may vary in tenor and range, which may be of one year or more. See also “—Financing Activities” below.

The current global financial crisis could impact our ability to access the financial markets in 2010. If it does so, we may be required to reduce our budgeted capital expenditures.

Effective January 1, 2009, in connection with the amendments to the Federal Law of Budget and Fiscal Accountability described under “Item 4—Information on the Company—History and Development—Capital Expenditures and Investments,” Petróleos Mexicanos assumed primary responsibility for the payment of all indebtedness of the Master Trust and Fideicomiso F/163, respectively. However, the Master Trust and Fideicomiso F/163, as applicable, continued to act as servicer of all indebtedness until Petróleos Mexicanos legally assumed, as primary obligor, their indebtedness under the related agreements. These legal assumptions were carried out during the second half of 2009.

Effective January 30, 2009, the Master Trust and Fideicomiso F/163 assigned certain rights to Petróleos Mexicanos in consideration of the cancellation of debt that these entities had issued to Petróleos Mexicanos between 2006 and 2008 pursuant to several inversiones de disponibilidades (which we refer to as inter-company private placements). The inter-company private placements were debt securities issued by the Master Trust or by Fideicomiso F/163 and purchased by Petróleos Mexicanos at prevailing market conditions. Under this program, which allowed Petróleos Mexicanos to invest part of its cash position in debt securities for use in PIDIREGAS, we were able to obtain significant benefits because the interest rate paid by these entities to Petróleos Mexicanos exceeded the average return on our cash investments. Additionally, the inter-company private placements did not increase our total indebtedness on a consolidated basis since they were eliminated as part of the consolidation process. Petróleos Mexicanos obtained all the required legal and corporate authorizations to establish this program. Through December 31, 2008, the Master Trust had issued U.S. $26.2 billion in debt securities through inter-company private placements to Petróleos Mexicanos and Fideicomiso F/163 had issued an additional Ps. 42.0 billion through inter-company private placements through December 31, 2008. All of these inter-company private placements were canceled effective January 30, 2009, as a result of the changes to the Federal Law of Budget and Fiscal Accountability that became effective in November 2008.

A number of our financing agreements contain restrictions on (a) our ability to create liens on our assets to secure external indebtedness, subject to certain exceptions, (b) our ability to enter into forward sales of crude oil or natural gas, receivables financings and advance payment arrangements, subject to certain baskets, and (c) our ability to merge or consolidate with other entities or to sell all or substantially all of our assets. In addition, a number of our financing agreements contain events of default, including an event of default if the Mexican Government ceases to control Petróleos Mexicanos, or if Petróleos Mexicanos or any of Pemex-Exploration and Production, Pemex-Refining or Pemex-Gas and Basic Petrochemicals ceases to have the exclusive right and authority to conduct the petroleum industry on behalf of Mexico. At December 31, 2009 and at the date of this report, we were not in default on any of our financing agreements.

In order to be able to carry out our planned capital expenditures program, we will need to seek financing from a variety of sources, and we cannot guarantee that we will be able to obtain financing on terms that would be acceptable to us. Our inability to obtain additional financing could have an adverse effect on our planned capital expenditures program and result in our being required to limit or defer this program.

Rating Agency Considerations

On May 11, 2009, S&P revised PEMEX’s ratings outlook from stable to negative, but affirmed its long-term foreign currency credit rating of BBB+ and its long-term local currency credit rating of A-. Subsequently, on December 14, 2009, S&P revised PEMEX’s ratings outlook from negative to stable, downgraded PEMEX’s long-term foreign currency credit rating from BBB+ to BBB and upgraded PEMEX’s long-term local currency credit rating from A- to A. In addition, S&P removed PEMEX from its credit watch list of companies with the potential for developing positive credit implications or improvements in ratings. These revisions from S&P followed its June 2009 publication of a new methodology for rating government-related entities, such as PEMEX. Additionally, on December 23, 2009, Moody’s affirmed its Baa1 rating of PEMEX’s long-term foreign currency denominated debt.

Financing Activities of Pemex Finance, Ltd.

Commencing on December 1, 1998, Petróleos Mexicanos, Pemex-Exploration and Production, PMI and P.M.I. Services, B.V. have entered into several agreements with Pemex Finance, Ltd. Under these contracts, Pemex Finance, Ltd. purchases certain existing PMI accounts receivable for crude oil as well as certain accounts receivable to be generated in the future by PMI related to crude oil. The receivables sold are those generated by the sale of Maya crude oil to designated customers in the United States, Canada and Aruba. The net proceeds obtained by Pemex-Exploration and Production from the sale of such receivables under the agreements are utilized for capital expenditures. Pemex Finance, Ltd. obtains resources for the acquisition of such accounts receivable through the placement of debt instruments in the international markets.

On July 1, 2005, we entered into an option agreement with BNP Paribas Private Bank and Trust Cayman Limited to acquire 100% of the shares of Pemex Finance, Ltd. As a result, the financial results of Pemex Finance, Ltd., under Mexican FRS are consolidated into the financial statements of Petróleos Mexicanos. Consequently, sales of accounts receivable by Pemex Finance, Ltd. have been reclassified as debt. The option to purchase the shares of Pemex Finance, Ltd. can only be exercised once its remaining debt, which was approximately U.S. $902.6 million as of December 31, 2009, has been redeemed.

As of December 31, 2009, the outstanding debt of Pemex Finance, Ltd. was composed of U.S. $893.3 million aggregate principal amount of notes with maturities ranging from 2010 to 2018 and interest rates between 8.875% and 10.61%, as well as two series of floating rate notes.

2010 Financing Activities. During the first five months of 2010, Pemex Finance, Ltd. made payments of U.S. $106.7 million in principal of its notes. Pemex Finance, Ltd. did not incur any additional indebtedness during the first five months of 2010.

2009 Financing Activities. During 2009, Pemex Finance, Ltd. made payments of U.S. $303.3 million in principal of its notes. Pemex Finance, Ltd. did not incur any additional indebtedness during 2009.

2008 Financing Activities. During 2008, Pemex Finance, Ltd. made payments of U.S. $333.0 million in principal of its notes. Pemex Finance, Ltd. did not incur any additional indebtedness during 2008.

Contractual Obligations and Off-Balance Sheet Arrangements

Information about our long-term contractual obligations and off-balance sheet arrangements outstanding as of December 31, 2009 is set forth below. This information is important in understanding our financial position. In considering the economic viability of investment opportunities, we view any source of financing, for example, operating leases or sales of future accounts receivable, as being economically equivalent to consolidated debt.

2009 Compared to 2008

Exploration and Production

In 2009, Pemex-Exploration and Production’s sales of crude oil to the PMI Group decreased by 26.5% in peso terms and by 40.8% in U.S. dollar terms, each as compared to 2008, mainly due to a decrease in the average sales prices and volumes of our principal petroleum products. The weighted average price of crude oil sold by Pemex-Exploration and Production to the PMI Group for export was U.S. $57.44 in 2009, as compared to U.S. $84.26 in 2008. Intersegment sales decreased by 27.3%, principally as a result of the decrease in crude oil export prices. Net income related to exploration and production activities decreased by 76.8%, or Ps. 18,037 million, from Ps. 23,473 million in 2008 to Ps. 5,436 million in 2009, primarily as a result of the decrease in the average price of crude oil and a decrease in crude oil production.

Refining

In 2009, trade sales related to refining activities decreased by 4.3%, from Ps. 490,556 million in 2008 to Ps. 469,614 million in 2009, due to a decrease in the average sales prices and volumes of our principal petroleum products. Intersegment sales increased by Ps. 4,009 million, or 7.0%, from Ps. 56,992 million in 2008 to Ps. 61,001 million in 2009, mainly due to higher demand for our principal petroleum products. In 2009, the total loss related to refining activities was Ps. 92,455 million, 22.6% less than the loss of Ps. 119,475 million in 2008. The decrease in loss was primarily due to lower operating costs and expenses.

Gas and Basic Petrochemicals

In 2009, trade sales related to the natural gas and basic petrochemical business segment decreased by 33.4%, from Ps. 167,108 million in 2008 to Ps. 111,245 million in 2009. LPG sales decreased by 11.6%, from Ps. 55,972 million in 2008 to Ps. 49,461 million in 2009, principally due to a decrease in LPG prices. Natural gas

131

sales decreased by 43.9%, from Ps. 106,821 million in 2008 to Ps. 59,916 million in 2009, mainly due to a decrease in natural gas prices. Income related to natural gas and basic petrochemicals decreased by 152.6%, or Ps. 3,454 million, from Ps. 2,264 million in 2008 to a loss of Ps. 1,190 million in 2009, mainly due to decreased sales, which were partially offset by decreased cost of sales, operating costs and expenses.

Petrochemicals

In 2009, trade sales related to the petrochemicals business segment decreased by 26.2%, from Ps. 25,576 million in 2008 to Ps. 18,885 million in 2009. Prices for petrochemicals sold domestically decreased for a majority of our petrochemical products. In 2009, the volume of petrochemical exports increased by 28.7%, from 590.9 thousand tons in 2008 to 760.3 thousand tons in 2009. Losses related to petrochemical activities increased by 7.1%, from Ps. 18,671 million in 2008 to Ps. 19,998 million in 2009, mainly due to decreased sales.

Corporate and subsidiary companies

In 2009, trade sales relating to PMI’s exports of crude oil and petroleum products to third parties and the trading activities of the PMI Group decreased by 24.1% in peso terms, from Ps. 645,710 million in 2008 to Ps. 490,176 million in 2009, as a result of lower prices of the crude oil that we exported and a reduction in the volume of crude oil exports. In 2009, net income related to corporate and subsidiary companies after inter-company eliminations, which includes the international trading activities of the PMI Group, increased from Ps. 332 million in 2008 to Ps. 13,545 million in 2009, primarily due to a decrease in related expenses and an increase in services income.

2008 Compared to 2007

Exploration and Production

In 2008, Pemex-Exploration and Production’s sales of crude oil to the PMI Group increased by 10.9% in peso terms and by 14.2% in U.S. dollar terms, each as compared to 2007, mainly due to an increase in the average sales prices and volumes of our principal petroleum products. The weighted average price of crude oil sold by Pemex-Exploration and Production to the PMI Group for export was U.S. $84.26 in 2008, as compared to U.S. $61.57 in 2007. Intersegment sales increased by 24.7%, principally as a result of the increase in crude oil export prices. Net income related to exploration and production activities increased by 17.6%, or Ps. 3,507 million, from Ps. 19,966 million in 2007 to Ps. 23,473 million in 2008, primarily as a result of an increase in the average price of crude oil.

Refining

In 2008, trade sales related to refining activities increased by 13.1%, from Ps. 433,604 million in 2007 to Ps. 490,556 million in 2008, due to an increase in the average sales prices and volumes of our principal petroleum products. Intersegment sales increased by Ps. 14,762 million, or 35.0%, to Ps. 56,992 million, mainly due to higher prices of our principal petroleum products. In 2008, the total loss related to refining activities was Ps. 119,475 million, 161.7% more than the loss of Ps. 45,654 million in 2007. The loss was primarily due to higher prices and volume of purchases by Pemex-Refining of imported petroleum products, mainly gasoline and diesel, which reduced its margins.

Gas and Basic Petrochemicals

In 2008, trade sales related to the natural gas and basic petrochemical business segment increased by 19.4%, from Ps. 139,963 million in 2007 to Ps. 167,108 million in 2008.

132

gas sales increased by 29.8%, from Ps. 82,295 million in 2007 to Ps. 106,821 million in 2008, mainly due to an increase in natural gas prices. Income related to natural gas and basic petrochemicals decreased by 54.3%, or Ps. 2,694 million, from Ps. 4,958 million in 2007 to Ps. 2,264 million in 2008, mainly due to an increase in operating and labor costs.

Petrochemicals

In 2008, trade sales related to the petrochemicals business segment increased by 17.9%, from Ps. 21,702 million in 2007 to Ps. 25,576 million in 2008. Prices for petrochemicals sold domestically increased for a majority of our petrochemical products. In 2008, the volume of petrochemical exports decreased by 11.2%, from 665.6 thousand tons in 2007 to 590.9 thousand tons in 2008. Losses related to petrochemical activities increased by 16.1%, from Ps. 16,086 million in 2007 to Ps. 18,671 million in 2008, mainly due to an increase in the volume of imports of methanol and xylene.

Corporate and subsidiary companies

In 2008, trade sales relating to PMI’s exports of crude oil and petroleum products to third parties and the trading activities of the PMI Group increased by 18.7% in peso terms, from Ps. 543,988 million in 2007 to Ps. 645,710 million in 2008, as a result of increased prices of the crude oil that we exported. In 2008, net income related to corporate and subsidiary companies after inter-company eliminations, which includes the international trading activities of the PMI Group, decreased from Ps. 18,508 million in 2007 to Ps. 332 million in 2008, primarily due to the expense associated with an increase in the reserve for employee benefits.

U.S. GAAP Reconciliation

Net income (loss) under U.S. GAAP differs from net income (loss) under Mexican FRS due to several factors, which include differences in methods of accounting for exploration and drilling costs, pension, seniority premiums and post-retirement benefit obligations, accrued vacation, capitalized interest, impairment of fixed assets, depreciation, derivatives, profit in inventory, deferred taxes, reclassification of Pemex Finance, Ltd. net income to non-controlling interest and our investment in Repsol shares. The amounts of these adjustments vary each year. For further information regarding these and other differences between Mexican FRS and U.S. GAAP as they relate to our results, see Note 21 to our consolidated financial statements included herein.

Income (Loss) and Equity (Deficit) under U.S. GAAP

For the year ended December 31, 2009, our loss under U.S. GAAP was approximately Ps. 52.6 billion, representing a Ps. 42.1 billion decrease from the net loss recorded under Mexican FRS. For the year ended December 31, 2008, our net loss under U.S. GAAP was approximately Ps. 67.8 billion, representing a Ps. 44.3 billion decrease from the net loss recorded under Mexican FRS. For the year ended December 31, 2007, our net loss under U.S. GAAP was approximately Ps. 32.6 billion, representing a Ps. 14.3 billion increase from the net loss recorded under Mexican FRS. For further detail regarding the adjustments related to these amounts, see Note 21 to our consolidated financial statements included herein.

Our equity deficit under U.S. GAAP was approximately Ps. 423.2 billion at December 31, 2009, as compared to an equity deficit of Ps. 145.4 billion at December 31, 2008. For further detail regarding the adjustments related to these amounts, see Note 21 to our consolidated financial statements included herein.

Recently Issued Accounting Standards

New Mexican FRS Accounting Standards

Accounting basis for the preparation of financial information

The accompanying consolidated financial statements have been prepared in accordance with Mexican FRS as promulgated by the Consejo Mexicano para la Investigación y Desarollo de Normas de Información Financiera, A.C. (Mexican Financial Reporting Standards Board, or CINIF).

Certain line items from the financial statements as of December 31, 2007 and 2008 have been reclassified in order to make the presentation of such financial statements comparable to that of the financial statements as of December 31, 2009.

New NIFs issued by the CINIF

The CINIF has issued the following NIFs, effective for fiscal years beginning as of January 1, 2010 or 2011, as indicated below:

• FRS B-5 “Financial Information by Segments,” which will take effect as of January 1, 2011 and supersedes Bulletin B-5 “Financial Information by Segment.” The principal changes established by this FRS are: (1) it requires that the information to be disclosed by operating segment be that which is regularly used by senior management; (2) it establishes that such information need not be segregated into primary and secondary categories, nor refer to segments identified on the basis of particular goods or services (economic segments), geographic areas or homogeneous groups of customers; (3) it requires that a reporting entity disclose aggregate information about its goods or services, geographical areas and main customers and suppliers; (4) it does not require that, in order to qualify as operating segments, the reporting entity’s business areas be subject to distinct types of risks; (5) it permits the business areas to be classified as operating segments during the pre-operations phase; (6) it requires the disclosure, by segment and separately, of interest income and expenses, as well as other components of the comprehensive financing result; (7) in certain situations, it permits disclosure of net interest income; and (8) it requires disclosure of the amounts of the liabilities included in the operating segment regularly used by senior management in making the reporting entity’s operating decisions. We estimate that the initial effects of this new FRS will not be material.

• FRS B-9 “Financial Information at Interim Dates,” which will take effect as of January 1, 2011 and supersedes Bulletin B-9 “Financial Information at Interim Dates.” The principal changes established by this FRS are: (1) it requires that financial information at interim dates include, in condensed and comparative form, in addition to the statements of financial condition and of income, the statement of changes in shareholders’ equity and the statement of cash flows, as well as—in the case of non-profit entities—presentation of the statement of activities; (2) it establishes that the financial information presented at the close of an interim period be presented comparatively with its equivalent interim period from the prior year, and, in the case of the balance sheet, that it also be compared with such financial statement as at year-end for the immediately preceding period; and (3) it incorporates and defines new terminology. We estimate that the initial effects of this new FRS will not be material.

• FRS C-1 “Cash and Cash Equivalents,” which will take effect as of January 1, 2010 and supersedes Bulletin C-1, “Cash.” The principal changes established by this FRS are: (1) it requires that cash and restricted cash equivalents be presented on the balance sheet under the heading “Cash and cash equivalents”; (2) the term “temporary investments on demand” is replaced by the term “investments available on demand”; (3) it includes, as a criterion for identifying investments available on demand, that they must be immediately available securities, such as investments with a maturity of no more than three months as of their acquisition date; and (4) it includes definitions of the following terms: “acquisition cost,” “cash equivalents,” “cash and restricted cash equivalents,” “investments available on demand,” “net realization value,” “par value” and “fair value.” We estimate that the initial effects of this new FRS will not be material.

In October 2009, the FASB issued Accounting Standards Update (ASU) 2009-13, Revenue Recognition (Topic 605): “Multiple-Deliverable Revenue Arrangements” (which we refer to as ASU 2009-13). ASU 2009-13 amends ASC Subtopic 605-25 “Multiple-Element Arrangements” to eliminate the requirement that all undelivered elements have vendor specific objective evidence (VSOE) of selling price or third party evidence (TPE) of selling price before a reporting entity can recognize the portion of an overall arrangement fee that is attributable to items that already have been delivered. In the absence of VSOE and TPE for one or more delivered or undelivered elements in a multiple-element arrangement, entities will be required to estimate the selling prices of those elements. The overall arrangement fee will be allocated to each element (both delivered and undelivered items) based on their relative selling prices, regardless of whether those selling prices are evidenced by VSOE or TPE or are based on the entity’s estimated selling price. Application of the “residual method” of allocating an overall arrangement fee between delivered and undelivered elements will no longer be permitted upon adoption of ASU 2009-13. Additionally, the new guidance will require entities to disclose more information about their multiple-element revenue arrangements. ASU 2009-13 is effective prospectively for revenue arrangements entered into or materially modified in a reporting entity’s fiscal years beginning on or after June 15, 2010. However, early adoption is permitted. We estimate that the initial effects of this new ASU will not be material.

In December 2009, the FASB issued ASU 2009-16, Transfers and Servicing (Topic 860): “Accounting for Transfers of Financial Assets” (which we refer to as ASU 2009-16). ASU 2009-16 removes the concept of a qualifying special-purpose entity (QSPE) from ASC Topic 860 “Transfers and Servicing” (which we refer to as Topic 860), and eliminates also the exception from applying ASC Subtopic 810-10 “Consolidation” (which we refer to as Subtopic 810-10) to QSPEs, thereby requiring transferors of financial assets to evaluate whether to consolidate transferees that previously were considered QSPEs. Transferor-imposed constraints on transferees whose sole purpose is to engage in securitization or asset-backed financing activities are evaluated in the same manner under the provisions of ASU 2009-16 as transferor-imposed constraints on QSPEs were evaluated under the provisions of Topic 860 prior to the effective date of ASU 2009-16 when determining whether a transfer of financial assets qualifies for sale accounting. ASU 2009-16 also clarifies the Topic 860 sale accounting criteria pertaining to legal isolation and effective control, and creates more stringent conditions for reporting a transfer of a portion of a financial asset as a sale. ASU 2009-16 is effective for a reporting entity’s annual as well as interim periods, beginning with its first annual reporting period that begins after November 15, 2009. Early adoption is not permitted. We estimate that the initial effects of this new ASU will not be material.

In December 2009, the FASB issued ASU 2009-17, Consolidations (Topic 810): “Improvements to Financial Reporting by Enterprises Involved with Variable Interest Entities” (which we refer to as ASU 2009-17). ASU 2009-17 amends the VIE Subsections of Subtopic 810-10 and, overall, revises the test for determining the primary beneficiary of a VIE—from a primarily quantitative calculation of risks and rewards, based on the VIE’s expected losses and expected residual returns, to a primarily qualitative analysis based on identifying the party or related-party group (if any) with (a) the power to direct the activities that most significantly impact the VIE’s economic performance and (b) the obligation to absorb losses of, or the right to receive benefits from, the VIE that could potentially be significant to the VIE. ASU 2009-17 requires that kick-out rights and participating rights be ignored in evaluating whether a variable interest holder meets the power criterion, unless those rights are unilaterally exercisable by a single party or related party group. ASU 2009-17 also revises the criteria for determining whether fees paid by an entity to a decision maker or another service provider are a variable interest in the entity, and revises the scope characteristic in ASC Topic 810 “Consolidations” that identifies an entity as a VIE if equity-at-risk investors as a group do not have the right to control the entity through their equity interests, in order to address the impact of kick-out rights and participating rights on the analysis. Finally, ASU 2009-17 adds a new requirement to reconsider whether an entity is a VIE if the holders of the equity investment at risk, as a group, lose the power, through the rights of those interests, to direct the activities that most significantly impact the VIE’s economic performance; it further requires a company to reassess on an ongoing basis whether it is deemed to be the primary beneficiary of a VIE. ASU 2009-17 is effective for a reporting entity’s annual as well

135

as interim periods, beginning with its first annual reporting period that begins after November 15, 2009. Early adoption is not permitted. We estimate that the initial effects of this new ASU will not be material.

Item 6. Directors, Senior Management and Employees

Under the Petróleos Mexicanos Law, Petróleos Mexicanos is governed by a 15 member Board of Directors composed as follows:

• The President of Mexico appoints six members, who are Mexican Government representatives. These include the Chairperson, who is the Secretary of Energy.

• The Sindicato de Trabajadores Petroleros de la República Mexicana (Petroleum Workers’ Union) selects five directors from among the employees of Petróleos Mexicanos and the subsidiary entities.

• Four professional members, who are Mexican Government representatives, are appointed by the President of Mexico, subject to ratification by the Senate.

Except in the case of the professional members, who cannot designate alternates, alternate directors are authorized to serve on the Board of Directors of Petróleos Mexicanos in place of those who are unable to attend meetings or otherwise participate in the activities of the Board of Directors of Petróleos Mexicanos. Budgetary actions can only be approved by the directors who are Mexican Government representatives.

Each of the Boards of Directors of the subsidiary entities is to be composed of:

• the Director General of Petróleos Mexicanos, who will be the Chairperson;

• Mexican Government representatives appointed by the President of Mexico; and

• at least two professional members appointed by the President of Mexico, who will be Mexican Government representatives. The number of professional members on each Board of Directors cannot exceed that of the other Mexican Government representatives on such Board of Directors.

As of the date of this report, the professional members have been appointed to the Board of Directors of Petróleos Mexicanos, as described below, but have not yet been appointed to the Boards of Directors of the subsidiary entities.

Except in the case of the professional members first appointed under the Petróleos Mexicanos Law, the four professional members will be appointed to six year terms, and may be appointed for an additional term of the same length. Other members of the Boards of Directors of Petróleos Mexicanos and each of the subsidiary entities are not appointed for a specific term.

In February 2009, President Calderón nominated the individuals named below to serve as professional members to the Board of Directors of Petróleos Mexicanos; their appointments were ratified by the Senate on March 17, 2009. The professional members will serve initial terms as set forth below.

• Mr. Fluvio César Ruíz Alarcón, for three years;

• Mr. Rogelio Gasca-Neri, for four years;

• Mr. Héctor Moreira Rodríguez, for five years; and

• Mr. José Fortunato Álvarez Enríquez, for six years.

On May 14, 2009, Mr. Alejandro Fleming Kauffman, Head of the Legal Affairs Unit of the Ministry of Energy, was ratified as Secretary of the Board of Directors of Petróleos Mexicanos. On December 18, 2009, Mr. Iván Aleksei Alemán Loza, Technical Secretary of the Director General of Petróleos Mexicanos, was appointed as Alternate Secretary.

136

On January 15, 2010, Mr. Felipe Mellado Flores was appointed Comisario (Commissioner) of Petróleos Mexicanos by President Calderón. In accordance with the Petróleos Mexicanos Law, the Commissioner, among other activities, will represent the holders of the Citizen Bonds and will report on the operational and financial condition of Petróleos Mexicanos.

The Organic Statute of Petróleos Mexicanos, which became effective as of September 25, 2009, establishes the structure, organizational basis and functions of the administrative units of Petróleos Mexicanos, and also delineates the duties and internal regulations of the Board of Directors of Petróleos Mexicanos.

On December 18, 2009 and January 25, 2010, the Board of Directors of Petróleos Mexicanos authorized several actions relating to the reorganization of Petróleos Mexicanos and the subsidiary entities, which are in the process of being implemented. These include:

• the elimination of the Corporate Engineering and Project Development Office, the activities of which will be carried out in the future by the Corporate Operations Office of Petróleos Mexicanos and by the subsidiary entities;

• the assignment of the finance and management activities previously carried out by the subsidiary entities to the Corporate Finance Office of Petróleos Mexicanos; and

• the creation of the new Corporate Office of Information Technology and Business Processes of Petróleos Mexicanos.

The following tables set forth certain information with respect to directors and executive officers of Petróleos Mexicanos and each of the subsidiary entities as of June 15, 2010.

The Petroleum Workers’ Union represents approximately 72% of the work force of Petróleos Mexicanos and the subsidiary entities. Petroleum Workers’ Union members are our employees and they elect their own leadership from among their ranks. Since the Petroleum Workers’ Union’s official establishment in 1938, we have experienced no labor strikes, and although we have experienced work stoppages for short periods of time, none of these stoppages has had a significant material adverse effect on our operations.

Our relationship with our employees is regulated by the Ley Federal del Trabajo (Federal Labor Law) and a collective bargaining agreement between Petróleos Mexicanos and the Petroleum Workers’ Union. The collective bargaining agreement regulates extensively all aspects of the relationship of Petróleos Mexicanos and the subsidiary entities with their employees. The collective bargaining agreement is subject to renegotiation every two years, although salaries are reviewed annually.

On July 23, 2009, Petróleos Mexicanos and the Petroleum Workers’ Union entered into a new collective bargaining agreement that became effective on August 1, 2009. The terms of the agreement provided for a 4.9% increase in wages and a 1.5% increase in other benefits. By its terms, the current collective bargaining agreement is scheduled to expire on July 31, 2011.

In accordance with the collective bargaining agreement and the Federal Labor Law, Petróleos Mexicanos and the subsidiary entities are under an obligation to pay seniority premiums to retiring employees and pensions to retired employees, as well as death benefits and pensions to the survivors of retired employees. Retirees are entitled to receive increases in their pensions whenever salary increases are granted to current employees. We also provide health and medical benefits to employees, retired employees and their families and, subject to our overall budgetary constraints, we provide an interest-rate subsidy on employees’ mortgage loans.

On November 5, 1997, the SHCP and the Board of Directors of Petróleos Mexicanos authorized the formation of a trust called the Pemex Labor Fund. This fund is a vehicle to fund labor liabilities, current pension payments and seniority premiums. We have designed a contribution plan to increase the funds held in this trust and to continue to make payments on outstanding labor and pension liabilities. Our contributions to the plan assets for the retirement benefits of PEMEX totaled Ps. 17,949 million in 2008 and Ps. 20,331 million in 2009.

Item 7. Major Shareholders and Related Party Transactions

Major Shareholders

Petróleos Mexicanos and the subsidiary entities have no shareholders because they are decentralized public entities of the Mexican Government. The Mexican Government closely regulates and supervises our operations; it incorporates the annual budget and financing programs of Petróleos Mexicanos and the subsidiary entities into its consolidated annual budget, which it submits to the Mexican Congress for approval.

Mexican Government secretaries hold six of the 15 seats on the Board of Directors of Petróleos Mexicanos, and the Secretary of Energy is the Chairperson of the Board of Directors of Petróleos Mexicanos. An additional four seats on the Board of Directors are held by professional members appointed by the President of Mexico and ratified by the Senate. The various committees of the Board of Directors are comprised only of Mexican Government representatives, i.e., a combination of Mexican Government secretaries and professional members of the Board of Directors. The Director General of Petróleos Mexicanos is a member of the President of Mexico’s cabinet. See also “Item 3—Key Information—Risk Factors—Risk Factors Related to the Relationship between PEMEX and the Mexican Government.”

Related Party Transactions

Under Article 8, Section XI of the Ley Federal de Responsabilidades Administrativas de los Servidores Públicos (Federal Law of Administrative Responsibilities of Public Officials), which applies to all of our employees, our employees are obligated to “recuse themselves from intervening in any way in the attention to, processing or resolution of matters in which they might have personal, family or business interest, including those where some benefit can result for themselves, their spouse, blood or affinity relatives up to the fourth degree, or civil relatives, or for third parties with which they have professional, labor or business relations, or for partners or partnerships where the public officials or the persons referred above are or have been members thereof.”

Additionally, in accordance with the Petróleos Mexicanos Law, a member of the Board of Directors of Petróleos Mexicanos or of the board of directors of a subsidiary entity may be removed from his or her position for, among other causes: (1) utilizing for personal benefit or for the benefit of any third party the information made available to him or her in connection with the exercise of his or her duties as a member; (2) disclosing such information in violation of applicable law; or (3) not recusing him or herself from discussion of and voting on matters in respect of which he or she has a conflict of interest. A member of the Board of Directors of Petróleos Mexicanos or of the board of directors of a subsidiary entity who acts in contravention of the Petróleos Mexicanos Law may be held liable for any damages thereby caused to Petróleos Mexicanos or a subsidiary entity.

As an employee benefit, we offer salary advances to all of our eligible Petroleum Workers’ Union and non-union workers, including our executive officers, pursuant to the programs set forth in the collective bargaining agreement and in the Reglamento de Trabajo del Personal de Confianza de Petróleos Mexicanos y Organismos Subsidiarios (Employment Regulation of White Collar Employees of Petróleos Mexicanos and Subsidiary Entities), respectively. The salary advances, which are non-interest bearing, are offered to each eligible employee in an amount up to a maximum of four months’ salary and are repaid through salary deductions in equal installments over a period of either one or two years, as elected by the employee. Most of our employees take advantage of this benefit. The largest amount of salary advances outstanding to executive officers at any one time during 2009 was Ps. 20.2 million. As of May 31, 2010, the aggregate amount of salary advances outstanding to our executive officers was Ps. 19.3 million.

Item 8. Financial Information

Legal Proceedings

In the ordinary course of our business, we are named in a number of lawsuits of various types. We evaluate the merit of each claim and assess the likely outcome, accruing a contingent liability when an unfavorable decision is probable and the amount is reasonably estimable. Other than as disclosed below, we do not believe a materially unfavorable outcome is probable for any known or pending lawsuits or threatened litigation for which we have not made any accruals. At December 31, 2009, the amount claimed in connection with these lawsuits totaled approximately Ps. 44.3 billion. At December 31, 2009, we had accrued a reserve of Ps. 9.9 billion for the contingent liabilities described below.

Labor-Related Proceedings

We are a party to various legal actions involving labor claims of former and present employees. These labor disputes relate to severance payments, life insurance benefits, extensions of labor contracts, level of wages, improper termination and employee housing. We do not expect these lawsuits to have a material adverse effect on our financial condition or future results of operations.

For information on our negotiations with the Petroleum Workers’ Union and collective bargaining agreements, see “Item 6—Directors, Senior Management and Employees—Employees.”

Mexican Government Audits and Other Investigations

Certain rules have been enacted in order to promote a culture of ethics and prevent corruption in our daily operations. On July 31, 2002, a Código de Ética de los Servidores Públicos de la Administración Pública Federal (Code of Ethics for Public Servants of the Federal Public Administration) was published in the Official Gazette of the Federation, containing rules to promote legality, honesty, integrity, loyalty, impartiality and efficiency in the performance of public work by public officers. On October 3, 2003, we announced a corporate code of conduct for Petróleos Mexicanos and the subsidiary entities, the Código de Conducta de Petróleos Mexicanos y Organismos Subsidiarios (Code of Conduct of Petróleos Mexicanos and the Subsidiary Entities) that defines the code of conduct expected from all employees of Petróleos Mexicanos and its subsidiary entities in the daily performance of their duties, and which is designed to promote transparency and prevent abuses. In addition, on May 12, 2004, the Board of Directors of Petróleos Mexicanos adopted a Code of Ethics for our chief executive officer, chief financial officer, chief accounting officer and all other employees performing similar functions in Petróleos Mexicanos, the subsidiary entities and the subsidiary companies. For more information on this Code of Ethics, see “Item 16B—Code of Ethics.” We expect that these efforts will result in a more effective system of internal controls.

In July 2007, the SFP announced that it had fined each of Mr. Raúl Muñoz Leos, ex-Director General of Petróleos Mexicanos and Mr. Juan Carlos Soriano Rosas, ex-General Counsel of Petróleos Mexicanos, an amount of Ps. 862.2 million and banned each of them from holding public office for ten years for allegedly breaking budgetary laws and regulations in connection with a side agreement (No. 10275/04) dated August 1, 2004, between Petróleos Mexicanos and the Petroleum Workers’ Union. On August 25, 2005, Petróleos Mexicanos and the Petroleum Workers’ Union amended this side agreement in order to make certain adjustments required by applicable regulations. These penalties have been appealed by the former officers and a final resolution of the matter is pending.

On December 12, 2008, the SEC filed a settled enforcement action charging Siemens AG with violations of the U.S. Foreign Corrupt Practices Act of 1977, as amended. Among other matters, the SEC alleged that two Siemens AG subsidiaries made three illicit payments totaling approximately U.S. $2.6 million to a consultant to assist in settling cost overrun claims in connection with three refinery upgrade projects, and that some portion of those payments was passed on to a senior PEMEX official.

170

In response to the allegations related to Siemens AG, on December 22, 2008, PEMEX requested an investigation concerning these alleged events, and on December 23, 2008, an investigation was formally initiated by the Internal Control Body of PEMEX, which is independent of PEMEX’s management and under the supervision of the SFP. The investigation is attempting to determine whether any person associated with PEMEX acted improperly in the matters related to the SEC allegations. A Mexican public official who in the course of his or her official duties acts in contravention of, or fails to act in accordance with, applicable law and regulations is subject to administrative penalties and criminal prosecution and punishment. Receipt of a payment to influence a decision regarding a contract would violate Mexican law and the Code of Ethics for Public Servants of the Federal Public Administration.

In May 2010, the SFP filed two criminal complaints and initiated an administrative proceeding against Mary Karen Miyazaki Hara, who served as PMI’s Deputy Director of Trading of Intermediate Distillates, for allegedly committing acts of corruption to the detriment of PMI in the amount of U.S. $13 million. The alleged acts involved the sale of ultra low sulfur diesel, to the economic benefit of foreign companies including Blue Oil Trading Ltd. As of the date of this report, this matter remains under investigation.

In March and April 2010, the SFP filed seven criminal complaints against public officials of Pemex-Refining, arising out of an investigation conducted by the Internal Control Body of Pemex-Refining, beginning in 2006. This investigation related to works executed in connection with a ruptured pipeline in Nanchital, Veracruz. It is alleged that the related agreement was executed in contravention of the applicable legal provisions, causing up to Ps. 1,065 million in damages to Pemex-Refining. In addition, the SFP imposed administrative penalties against these public officials, as well as contractors. These penalties have been appealed, and as of the date of this report, a final resolution is still pending.

Actions Against the Illicit Market in Fuels

In conjunction with the SHCP and the Ministry of Energy, we have implemented a number of measures to combat the illegal market in fuels, with the objective of minimizing losses of refined products caused by acts of theft, illegal extraction, tampering and illicit marketing of petroleum products and the associated risks to personnel, facilities and the environment. We report any unlawful activity of which we become aware to the appropriate local or federal authorities.

We have implemented a workplace operational technical assessment program, which has helped us to identify and eliminate areas of vulnerability. In addition, theft in the workplace has been reduced as a result of our analyzing the information provided by certain measurement systems, field surveillance and control instruments. These include mobile laboratories, volumetric control for service stations, terminal operations measurement, integrated control systems (SIMCOT), a satellite tracking system, closed circuit television and online measurement systems. Additionally, we have obtained information through dedicated interfaces in institutional information systems, which were put in place to detect any inconsistencies in the handling of fuels.

During 2009, we implemented several strategic measures in order to decrease incidents of theft in our facilities, including the following:

• The carrying out of 106 technical operational assessments in PEMEX facilities to detect those areas most vulnerable to illegal activities, along with the issuance of recommendations for preventing such activities.

• The acquisition of 18 new mobile laboratories, for a total of 42 mobile laboratories in operation (which total was increased in March 2010 to 53, upon the activation of 11 more such mobile laboratories). These mobile laboratories made 19,150 visits to service stations to verify the quality of the products being sold and discourage the sale of altered products.

• The detection, through the use of satellite tracking systems, of 25 cases of illegal re-routing of fuel deliveries to service stations and unauthorized sites involving PEMEX fuel tank trucks. A total of 17

171

PEMEX employees implicated in these cases received administrative sanctions in accordance with applicable law, including monetary fines or the suspension of their employment.

• The monitoring, with closed circuit television systems, of areas at 31 storage and distribution terminals where suspicious transactions were suspected of taking place.

• The performance of automated product handling and operations in 66 storage and distribution terminals, through the use of measurement and integrated control systems, which led to the timely identification of possible cases of illegal fuel extraction. Additionally, the use of the satellite tracking and closed circuit television systems discussed above has provided valuable evidence in resolving related administrative investigations.

• The installation and calibration of 60 flow meters at major custody transfer points, in order to measure volumes and determine product balances. Further, the addition of these flow meters has permitted the full automation of the custody transfer system and facilitated information analysis, which enhances the usefulness of the implemented metering equipment by permitting identification of pipelines where constant pressure drops are registered.

• The monitoring of fuel volumes at the service station level, by comparing PEMEX deliveries against retail sales, and thereby further improving volumetric control monitoring. PEMEX, in conjunction with the Procuraduría General de la República (Office of the Federal Attorney General) and the Tax Administration System, conducts physical product management inspection visits to service stations.

In connection with the effort to combat thefts in the national pipeline system, we carried out the following actions during 2009: the inspection of 4,687 kilometers of pipelines with the use of in-line devices known as go-devils; the re-inspection of certain vulnerable pipelines; and the ongoing evaluation of our monitoring activities. Also during 2009, in coordination with the Ministry of National Defense, the Secretary of the Navy and the Office of the Federal Attorney General, we identified and sealed off 439 illegal pipeline taps, as compared to 367 such taps in 2008. We proceeded, as well, in these cases to file the corresponding criminal reports.

The illicit market in fuels impacts our results of operations due to the loss of revenues that would have been generated from the sale of such products, the production cost of which is already included in our cost of sales. The preventive actions, conducting of in-line inspections and timely monitoring and analysis of pipeline pressure drops, each as described above, have allowed us to more quickly detect illegal pipeline taps, reducing our time of exposure to theft and thereby decreasing the estimated volumes of stolen product. The estimated volume loss for 2009 was 3,078,363 barrels, 38% less than the estimated loss of 4,984,571 barrels in 2008. In the period of May 2009 to December 2009 in particular, estimated lost volumes of product decreased by 69%, as compared to the same period of 2008, from 3,982,135 barrels to 1,228,416 barrels.

On August 18, 2009, Petróleos Mexicanos received a payment of U.S. $2.4 million from the Office of the Federal Attorney General to compensate PEMEX for the illegal sale by Trammo Petroleum Inc., a company based in Houston, Texas of condensates stolen from PEMEX facilities. The Office of the Federal Attorney General had received this sum from U.S. Immigration and Customs Enforcement.

On June 7, 2010, Pemex-Exploration and Production filed a civil claim before the United States District Court for the Southern District of Texas, following an investigation by Mexican and United States authorities of the illicit market for petroleum products originating in the Burgos basin. This investigation revealed the alleged participation of several companies, such as BASF Corporation, Murphy Energy Corporation, Trammo Petroleum Inc., Bio-UN Southwest, Inc., Valley Fuels and U.S. Petroleum Depot, Inc., along with several individuals who have pleaded guilty to criminal charges relating to this scheme. Pemex-Exploration and Production is seeking to recover the value of the petroleum condensate that it believes has been stolen.

172

As discussed above, in coordination with the SHCP and the Ministry of Energy, we have introduced a number of measures to combat the illegal trade in fuels, and we remain committed to continuing to take actions against such market.

Civil Actions

In September 2001, Conproca, S.A. de C.V. (which we refer to as CONPROCA), the construction company performing construction and maintenance services for Pemex-Refining’s Cadereyta refinery, filed a claim for arbitration before the International Court of Arbitration of the International Chamber of Commerce (the ICA) against Pemex-Refining and Petróleos Mexicanos (No. 11760/KGA) related to expenses incurred by CONPROCA for, among other things, additional work performed and value added. On December 17, 2008, the ICA issued a general liability award in favor of CONPROCA (of which Pemex-Refining was notified on December 22, 2008), without specifying an amount to be paid by Pemex-Refining or Petróleos Mexicanos. On November 30, 2009, the parties submitted briefs and evidence in support of the respective amounts of their claimed liability. CONPROCA is seeking a total amount of U.S. $424.9 million and Petróleos Mexicanos and Pemex-Refining are seeking U.S. $116 million. As of the date of this report, Petróleos Mexicanos and Pemex-Refining are preparing a brief in connection with a hearing to determine the amounts due to each party.

As of the date of this report, only one of the several claims filed by a group of Congressmen from the LIX^th Legislature related to the FPWC program (see “Item 4—Information on the Company—Business Overview—Pemex-Exploration and Production—Financed Public Works Contracts”) remains pending. Pemex-Exploration and Production has obtained favorable judgments in the other similar claims filed by these plaintiffs. This remaining claim (No. 226/2004-IV) is related to the FPWC entered into between Pemex-Exploration and Production and PTD Servicios Múltiples, S. de R.L. de C.V. for the Cuervito natural gas production block, and was filed before the Juzgado Noveno de Distrito en Materia Civil del Distrito Federal (Ninth Civil District Court of the Federal District). The claim does not seek monetary relief, but instead to prevent the performance of this FPWC through a declaration that it is void based on the alleged violation of Article 27 of the Political Constitution of the United Mexican States. On June 7, 2008, Pemex-Exploration and Production responded to this claim. On April 19, 2010, the court issued a resolution declaring that the period for legal action had lapsed. The plaintiffs filed an appeal of this resolution before the Primer Tribunal Unitario en Materia Civil del Primer Circuito (First Unit Civil Court of the First Circuit), which confirmed the resolution but released the plaintiffs from a requirement that they pay court expenses.

In July 2000, Petroquímica Cosoleacaque, S.A. de C.V. (PECOSA, which has since been merged into Pemex-Petrochemicals) filed a claim (No. 18/2000) against Afianzadora Insurgentes, S.A. de C.V. (Afianzadora Insurgentes) and Fianzas México Bital, S.A., Grupo Financiero Bital (Fianzas México) before the Juzgado Décimo de Distrito (Tenth District Court) in Coatzacoalcos, Veracruz. The claim seeks an award of approximately Ps. 218.8 million for a surety bond granted in favor of Agronitrogenados, S.A. de C.V., an ammonia customer of PECOSA. In June 2004, a judgment in favor of PECOSA was issued. In October 2004, the defendants filed an appeal. The Segundo Tribunal Colegiado del Décimo Circuito (Second Joint Court of the Tenth Circuit) in Villahermosa, Tabasco issued a new resolution on June 9, 2008 in favor of Pemex-Petrochemicals. Afianzadora Insurgentes was ordered to pay Ps. 141.3 million in principal, Ps. 6.9 million in interest and Ps. 50.7 million for delay. Fianzas México was ordered to pay Ps. 13.9 million in principal, Ps. 278,200 in interest and Ps. 5.8 million for delay. Both defendants were also ordered to pay the corresponding interest and value added tax related to this claim. In July 2008, each party filed a form of constitutional relief known as an amparo against this resolution. On March 4, 2009, the Primer Tribunal Colegiado del Décimo Circuito (First Joint Court of the Tenth Circuit) in the state of Tabasco admitted such amparos (No. 197/2009, No. 198/2009 and No. 199/2009) for consideration. The related resolutions are still pending.

In December 2004, Corporación Mexicana de Mantenimiento Integral, S. de R.L. de C.V. (COMMISA) filed an arbitration claim before the ICA against Pemex-Exploration and Production (arbitration related to project No. IPC-01) for, among other things, a breach of a construction agreement in connection with two platforms in

173

the Cantarell complex. The detailed claim filed by COMMISA seeks damages of U.S. $319.9 million and Ps. 37.2 million. Pemex-Exploration and Production responded to the claim and filed a counterclaim against COMMISA, seeking U.S. $125.9 million and Ps. 41.5 million. On January 13, 2010, the ICA notified Pemex-Exploration and Production that it had rendered a decision, dated December 16, 2009, requiring Pemex-Exploration and Production to pay COMMISA sums of approximately U.S. $293.6 million and Ps. 34.5 million, plus interest, but also requiring COMMISA to pay Pemex-Exploration and Production a sum of approximately U.S. $5.7 million, plus interest. On January 11, 2010, Pemex-Exploration and Production had been notified that COMMISA had filed a motion before the U.S. District Court for the Southern District of New York requesting the enforcement of the ICA award in its favor. As of the date of this report, Pemex-Exploration and Production is seeking to have this action dismissed. On July 1, 2010, a hearing will be held. In addition, Pemex-Exploration and Production has filed a motion before the Juzgado Quinto de Distrito en Materia Civil (Fifth Civil District Court), requesting that the award be declared null and void. The resolution of this claim is still pending.

In January 2006, Tejas Gas de Toluca, S. de R.L. de C.V. (TGT) commenced an arbitration proceeding against Gas Natural México, S.A. de C.V. (GNM) and Pemex-Gas and Basic Petrochemicals, seeking, among other things, to enforce compliance with a transportation agreement and its amendments dated February 2001 and November 2001. This agreement was entered into for the operation of the Palmillas-Toluca pipeline. On May 27, 2010, the parties executed a settlement agreement in connection with this claim. Additionally, they agreed to execute a new transportation agreement. On May 28, 2010, the parties notified the ICA of the settlement agreement, to facilitate its issuance of a final award on such terms.

On December 16, 2005, Asociación de Transportistas al Servicio de Petróleos Mexicanos, Clientes o Empresas Sustitutos, A.C. (Asociación de Transportistas) filed a claim (No. 271/2005-I) before the Juzgado Quinto de Distrito en Materia Civil (Fifth Civil District Court) in the Federal District seeking a declaration that Pemex-Refining was in breach of a transportation agreement dated March 26, 1993, as well as the payment of related damages. Asociación de Transportistas is also seeking that Pemex-Refining authorize the plaintiff to replace tank trucks older than ten years, register these new tank trucks and assign them a cargo. On April 29, 2008, a judgment was issued against Pemex-Refining. Pemex-Refining filed an appeal (No. 425/2008) against this resolution before the Primer Tribunal Unitario en materia Civil y Administrativa del Primer Circuito (First Unit Civil and Administrative Court of the First Circuit), which was granted on October 26, 2009. The plaintiff filed an amparo (No. 696/2009) against this resolution before the Décimo Segundo Tribunal Colegiado (Twelfth Joint Court), which affirmed the previous resolution in favor of Pemex-Refining. This proceeding has therefore concluded. In three other claims filed separately by Asociación de Transportistas against Pemex-Refining, judgments have been granted in favor of Pemex-Refining.

On August 20, 2007, Petróleos Mexicanos and Pemex-Refining were summoned before the Juzgado Decimocuarto de Distrito del Décimo Circuito (Fourteenth District Court of the Tenth Circuit) in Coatzacoalcos, Veracruz in connection with a civil claim (No. 12/2007) filed by Leoba Rueda Nava, seeking approximately Ps. 2,896.9 million for, among other things, civil liability and damages resulting from the pollution of land used to store oil waste. On May 19, 2010, a final judgment was issued in favor of the plaintiff. Petróleos Mexicanos and Pemex-Refining were ordered to pay Ps. 995.1 million plus interest, as well as expenses related to the claim. On May 26, 2010, the defendants filed an appeal against this judgment before a Tribunal Unitario del Décimo Circuito (Unit Court of the Tenth Circuit) in Villahermosa, Tabasco. As of the date of this report, a final resolution is still pending.

In December 2003, Unión de Sistemas Industriales, S.A. de C.V. filed a claim (No. 202/2003) before the Juzgado Tercero de Distrito en Materia Civil (Third Civil District Court) in the Federal District against Pemex-Refining, seeking approximately Ps. 393 million for, among other things, work performed and not paid for under a pipeline construction agreement, as well as expenses related to the claim. A final judgment was issued against Pemex-Refining in which it was ordered to pay Ps. 89.0 million. Both parties filed appeals (No. 204/2009 and No. 205/2009) against this resolution before the Segundo Tribunal Unitario en Materia Civil y Administrativa del Primer Circuito (Second Unit Civil and Administrative Court of the First Circuit). On November 23, 2009, a resolution was granted in favor of Pemex-Refining. The plaintiff filed an amparo (D.C. 03/2010) before the

174

Décimo Tribunal Colegiado en material Civil (Tenth Joint Civil Court) against this resolution. Pemex-Refining also filed an amparo (D.C. 04/2010) before the Tenth Joint Civil Court since it was ordered to grant a discharge in favor of the plaintiff. On May 26, 2010, a resolution was issued against Pemex-Refining’s amparo and in favor of the plaintiff’s. The court ordered that the pleadings filed by the plaintiff be analyzed. As of the date of this report, a final resolution is still pending.

On August 16, 2006, two separate amparos (No. 723/2006 and No. 724/2006) were filed by Minera Carbonífera Río Escondido, S.A. de C.V. and Minerales Monclova, S.A. de C.V. before the Juzgado Cuarto de Distrito en Materia Administrativa (Fourth Administrative District Court) in the Federal District, alleging that the Regulatory Law was unconstitutional and that Pemex-Exploration and Production had violated each entity’s constitutional rights by carrying out development, infrastructure and maintenance projects in non-associated gas fields under a public works contract. A constitutional hearing will be held on July 6, 2010. An expert’s opinion on geology to be filed by Pemex-Exploration and Production is still pending.

On April 14, 2010, Petróleos Mexicanos and Pemex-Gas and Basic Petrochemicals were summoned before the Juzgado Séptimo de Distrito (Seventh District Court) in Reynosa, Tamaulipas, in connection with a claim filed by Irma Ayala Tijerina de Barroso and others, seeking approximately Ps. 1,490.9 million for, among other things, civil liability and damages resulting from the pollution of land used for water treatment in the Reynosa GPC. On May 7, 2010, Petróleos Mexicanos and Pemex-Gas and Basic Petrochemicals responded to this claim, objecting that the court lacked jurisdiction to hear it. This objection was admitted and the principal claim has therefore been suspended. A final resolution is still pending.

In January 1993, Pemex-Refining entered into a joint venture with Impulsora Jalisciense, S.A. de C.V. (Impulsora) to establish a new company called Mexicana de Lubricantes, S.A. de C.V. (Mexicana de Lubricantes), which manufactures, bottles and distributes automotive and industrial lubricants and greases. Currently, Pemex-Refining is involved in certain litigation and administrative proceedings in connection with this joint venture, including the following:

• On December 5, 2005, Impulsora filed an amparo (No. 1519/2005) before the Juzgado Quinto de Distrito en Materia Administrativa (Fifth Administrative District Court) in the state of Jalisco, in connection with a constitutional challenge to the Ley Federal de Procedimiento Administrativo (Federal Law of Administrative Procedure) and a resolution (Acuerdo No. PMREF-00-002) modifying the franchise agreement among Pemex-Refining and the service stations franchised by Pemex-Refining. This proceeding has been joined with a pending claim filed by Bardahl de México, S.A. de C.V. (Bardahl), a competitor in the lubricants market, in which Bardahl asserts that it is the owner of the “Mexlub” trademark. As described further below, Bardahl seeks a ruling under which it would be permitted to sell its products in the service stations franchised by Pemex-Refining, thereby eliminating Mexicana de Lubricantes’ exclusive right to sell its lubricants in these service stations. A constitutional hearing will be held on July 9, 2010.

• On December 20, 2005, Pemex-Refining filed a commercial claim (No. 127/2005) against Mexicana de Lubricantes before the Juzgado Segundo de Distrito en Materia Civil (Second Civil District Court) in the state of Jalisco, to compel Impulsora to convene a general shareholders’ meeting to discuss Mexicana de Lubricantes’ financial information, as well as the appointment of its new board members and comptroller. On June 29, 2007, a judgment was issued in favor of Pemex-Refining, and Mexicana de Lubricantes was ordered to convene a general shareholders’ meeting. As of the date of this report, compliance with this final resolution is still pending.

• On June 7, 2006, Pemex-Refining filed a criminal complaint before the Federal Attorney General’s Office for fraud allegedly committed by members of the board of directors of Mexicana de Lubricantes. On July 17, 2009, Pemex-Refining filed an accounting report stating that it had suffered up to Ps. 25.8 million in damages as a result of this alleged fraud. As of the date of this report, an expert’s opinion to be provided by the Federal Attorney General’s Office is still pending, and the matter remains under investigation.

• On October 17, 2006, Pemex-Refining filed a commercial claim (No. 222/2006) against Impulsora before the Juzgado Octavo de Distrito en Materia Civil (Eight Civil District Court) in Mexico City, seeking to enforce its contractual right to exercise an option to purchase those shares of Mexicana de Lubricantes owned by Impulsora. On November 30, 2009, a judgment was issued in favor of Impulsora on the basis of Mexicana de Lubricantes’ financial statements not yet having been approved—which would be necessary in determining whether it had realized any profit. Pemex-Refining filed an appeal against this resolution, which was denied on April 29, 2010. Pemex-Refining was ordered to pay court expenses and filed an amparo (No. 345/2010) against this resolution before the Sexto Tribunal Colegiado en Materia Civil del Primer Circuito (Sixth Joint Civil Court of the First Circuit). A final resolution is still pending.

• On February 2, 2007, Mexicana de Lubricantes filed a commercial claim (No. 28/2007) against Pemex-Refining before the Juzgado Primero de Distrito en Materia Civil (First Civil District Court) in the Federal District seeking, among other things, a judgment declaring null and void any advance termination or cancellation of the following agreements executed between Mexicana de Lubricantes and Pemex-Refining: (i) a license and trademark contract; (ii) a basic greases supply contract; and (iii) a contract for the manufacture of lubricants and greases for Petróleos Mexicanos and the subsidiary entities. On March 16, 2010, a judgment was issued in favor of Pemex-Refining. Mexicana de Lubricantes and Pemex-Refining each filed an appeal against this resolution before the First Unit Civil and Administrative Court of the First Circuit. A final resolution is still pending.

• On May 2, 2007, Bardahl filed a commercial claim (No. 95/2007) against Mexicana de Lubricantes and Pemex-Refining before the Juzgado Quinto de Distrito en Materia Civil del Tercer Circuito (Fifth Civil District Court of the Third Circuit) in Guadalajara, Jalisco, seeking that a trademark license agreement between Pemex-Refining and Mexicana de Lubricantes and its amendments be declared invalid because of an exclusivity clause that prevents the sale of Bardahl’s products in the service stations franchised by Pemex-Refining, as well as related damages. The plaintiff’s expert claims that Bardahl’s damages total up to Ps. 18,008 million, while the defendants’ expert claims that there are no damages. The trial is in the evidentiary stage, with the opinion of an independent expert still pending.

• On November 3, 1997, the Comisión Federal de Competencia (Federal Competition Commission) initiated an investigation into Pemex-Refining’s business practices in connection with an exclusivity clause included in its license and trademark contracts executed with service stations franchised by Pemex-Refining, which provided that those service stations could only sell lubricants and greases bearing PEMEX or Mexicana de Lubricantes trademarks. On July 10, 2003, the Federal Competition Commission issued a resolution prohibiting Pemex-Refining from engaging in anti-competitive practices in relation to that exclusivity clause, requiring amendment of the related contracts within a period of six months to remove the clause and imposing a fine of 1,500 daily minimum wage units per day until such contracts were brought into compliance. However, this six-month deadline was suspended due to a motion filed by Impulsora. On January 23, 2008, the Federal Competition Commission notified Pemex-Refining that it would require compliance with the resolution described above within a period of no more than 15 business days, except for the requirement to amend the relevant contracts. On February 12, 2008, Pemex-Refining filed a response stating that it would be unable to comply with the resolution due to a definitive suspension granted to Bardhal in a related amparo (No. 373/2006, which is currently joined with amparo No. 1519/2005). On April 10, 2008, the Federal Competition Commission rejected this response and Pemex-Refining filed a subsequent motion to suspend the Federal Competition Commission’s resolution. That motion was granted on May 6, 2008. An amparo had been granted on April 30, 2008 in favor of Pemex-Refining, declaring unconstitutional the resolution originally issued by the Federal Competition Commission. The Federal Competition Commission filed a revised motion (No. R.A. 246/2008) before the Décimo Tribunal Colegiado del Primer Circuito (Tenth Joint Court of the First Circuit) objecting to the amparo, but that motion was denied. On September 28, 2009, the Federal Competition Commission reviewed the evidence filed by Pemex-Refining and ratified its initial resolution. On October 20, 2009, Pemex- Refining filed a new amparo (No. 1691/2009) before the Juzgado Décimo Tercero de Distrito en Materia Administrativa (Thirteenth Administrative District Court) in the Federal District, and a provisional suspension was granted. A constitutional hearing was to be held on June 17, 2010.

The result of these proceedings is uncertain until the final resolutions are issued by the appropriate authorities.

Dividends

In March 1990, as a result of the implementation of the 1989-92 Financing Package for Mexico, our commercial bank creditors exchanged U.S. $7.58 billion of Petróleos Mexicanos’ external indebtedness for Brady Bonds issued by the Mexican Government. At the same time, Petróleos Mexicanos’ indebtedness to the Mexican Government was increased by the same amount; the new indebtedness was denominated in currencies other than pesos. In December 1990, the Mexican Government and Petróleos Mexicanos agreed to capitalize this indebtedness, converting it into Certificates of Contribution “A.” As a condition of this capitalization, Petróleos Mexicanos agreed to pay a minimum guaranteed dividend to the Mexican Government equal to the debt service on the capitalized debt. The Board of Directors of Petróleos Mexicanos approves the total dividend on the Certificates of Contribution “A” after the end of each fiscal year, although until January 2007 Petróleos Mexicanos paid an amount equal to the minimum guaranteed dividend to the Mexican Government in monthly advance payments during the year. During 2005, 2006 and 2007, Petróleos Mexicanos made advance payments to the Mexican Government in aggregate annual amounts of Ps. 16,501 million, Ps. 269 million and Ps. 4,260 million, respectively, toward the minimum guaranteed dividends for those years. On January 2, 2007, Petróleos Mexicanos made its final advance payment of minimum guaranteed dividends. We do not have a dividend policy; the Mexican Government may require that we make dividend payments at any time. On August 20, 2008, the Board of Directors of Petróleos Mexicanos approved the payment of a Ps. 4,270 million dividend to the Mexican Government. No dividends were declared or paid in 2009. See “Item 5—Operating and Financial Review and Prospects—Liquidity and Capital Resources—Equity Structure and Certificates of Contribution ‘A.’”

Item 9. The Offer and Listing

Trading in the debt securities issued by Petróleos Mexicanos takes place primarily in the over-the-counter market. All the debt securities issued by Petróleos Mexicanos that are registered pursuant to the U.S. Securities Act of 1933 (which we refer to as the Securities Act) are also listed on the Luxembourg Stock Exchange and traded on the Euro MTF, the alternative market of the Luxembourg Stock Exchange.

Item 10. Additional Information

Memorandum and Articles of Association

The Mexican Congress established Petróleos Mexicanos by a decree dated June 7, 1938, effective July 20, 1938. None of Petróleos Mexicanos or the subsidiary entities has bylaws or articles of association. On July 17, 1992, the Mexican Congress created the subsidiary entities out of operations that had previously been directly managed by Petróleos Mexicanos. Petróleos Mexicanos and its four subsidiary entities, Pemex-Exploration and Production, Pemex-Refining, Pemex-Gas and Basic Petrochemicals and Pemex-Petrochemicals, are decentralized public entities of the Mexican Government, and each is a legal entity empowered to own property and carry on business in its own name. The activities of Petróleos Mexicanos and the subsidiary entities are regulated by the Political Constitution of the United Mexican States, the Regulatory Law, the Petróleos Mexicanos Law, Regulations to the Petróleos Mexicanos Law, regulations issued pursuant to the Regulatory Law and other federal laws and regulations. See “Item 4—Information on the Company—History and Development.” Under the Petróleos Mexicanos Law, the Board of Directors of Petróleos Mexicanos has the following committees: Audit and Performance Evaluation Committee, Transparency and Accountability Committee, Strategy and Investment Committee, Compensation Committee, Acquisitions, Leasing, Works and Services Committee, Environmental and Sustainability Committee and Development and Technological Research Committee. See “Item 6—Directors, Senior Management and Employees.”

177

Under the Federal Law of Administrative Responsibilities of Public Officials, our directors are obligated to abstain from voting on a proposal, arrangement or contract in which they have a personal, family or business interest. Our directors do not have the power to vote compensation to themselves or any other member of the board. Except in the case of the professional board members, our directors do not receive compensation for their services as members of the Boards of Directors of Petróleos Mexicanos and the subsidiary entities. Under the Federal Law of Administrative Responsibilities of Public Officials, our directors must perform their duties without obtaining or attempting to obtain any benefits greater than those granted by law. Therefore, our directors do not have borrowing powers exercisable by themselves. There is no requirement for early retirement for our directors.

Material Contracts

On November 10, 1998, Petróleos Mexicanos, The Bank of New York Mellon (formerly The Bank of New York) and The Bank of New York (Delaware) entered into a Trust Agreement, which created the Master Trust and designated The Bank of New York Mellon as Managing Trustee and The Bank of New York (Delaware) as Delaware Trustee. On the same date, Petróleos Mexicanos, the subsidiary entities (except for Pemex-Petrochemicals) and the Master Trust, acting through The Bank of New York Mellon, entered into an Assignment and Indemnity Agreement. This agreement provided for the assignment by such subsidiary entities to the Master Trust of certain payment obligations relating to PIDIREGAS, the arrangement by Petróleos Mexicanos of financing on behalf of the Master Trust to meet such payment obligations, the payment by Petróleos Mexicanos and such subsidiary entities to the Master Trust of the amounts necessary to meet the Master Trust’s obligations under such financings and the indemnification of the Master Trust by Petróleos Mexicanos and such subsidiary entities. The Trust Agreement was amended on each of November 17, 2004, December 22, 2004 and August 17, 2006, and the Assignment and Indemnity Agreement was amended on August 17, 2006. The purpose of the August 17, 2006 amendment was to include Pemex-Petrochemicals as a party to the Assignment and Indemnity Agreement. Effective January 30, 2009, the Master Trust and Fideicomiso F/163 assigned certain rights to Petróleos Mexicanos in consideration of the cancellation of debt that these entities had issued to Petróleos Mexicanos between 2006 and 2008 pursuant to several inter-company private placements. In addition, effective January 1, 2009, in connection with amendments to the Federal Law of Budget and Fiscal Accountability, Petróleos Mexicanos agreed to assume primary responsibility for the payment of all indebtedness of the Master Trust and Fideicomiso F/163, respectively. However, the Master Trust and Fideicomiso F/163 continued to act as servicers of all of this indebtedness until such time as Petróleos Mexicanos legally assumed, as primary obligor, their indebtedness under the related agreements. These assumptions occurred during the second half of 2009.

On December 30, 2004, the Master Trust and Petróleos Mexicanos entered into an indenture with Deutsche Bank Trust Company Americas (Deutsche Bank), as Trustee. This agreement provided for the issuance by the Master Trust from time to time of unsecured debt securities. All issuances of debt securities under this indenture were unconditionally guaranteed by Petróleos Mexicanos. Pursuant to a guaranty agreement, dated as of July 29, 1996, Petróleos Mexicanos’ obligations are jointly and severally guaranteed by Pemex-Exploration and Production, Pemex-Refining and Pemex-Gas and Basic Petrochemicals. Under the indenture, Petróleos Mexicanos was permitted, without the consent of the holders of the outstanding debt securities, to assume as primary obligor all of the Master Trust’s obligations under such debt securities in substitution of the Master Trust and, upon such assumption, the Master Trust would be released from its obligations under such debt securities. Effective September 30, 2009, Petróleos Mexicanos assumed all of the Master Trust’s obligations under the 2004 indenture and the debt securities issued under the 2004 indenture, and all of the Master Trust’s obligations under an indenture dated as of July 31, 2000, among the Master Trust, Petróleos Mexicanos and Deutsche Bank, as well as the debt securities issued under the 2000 indenture.

On each of February 11, 2005, February 23, 2007, October 11, 2007 and July 18, 2008, the Master Trust further increased the aggregate amount of debt securities issuable under its Medium-Term Notes program to U.S. $20,000,000,000, U.S. $30,000,000,000, U.S. $40,000,000,000 and U.S. $60,000,000,000, respectively.

178

Following these increases and pursuant to the 2004 indenture referred to above, the Master Trust issued various new series of securities. See “Item 5—Operating and Financial Review and Prospects—Liquidity and Capital Resources—Financing Activities.” All of the Master Trust’s obligations under these securities were assumed by Petróleos Mexicanos effective as of September 30, 2009.

As of December 31, 2008 and 2009, we have entered into contracts with various contractors for approximate amounts of Ps. 483,256 million and Ps. 195,097 million, respectively. These contracts are for the development of investment projects under the PIDIREGAS program, which projects will continue notwithstanding the changes to the Federal Law of Budget and Fiscal Accountability described above. See Note 3(g) to our consolidated financial statements included herein.

On January 27, 2009, Petróleos Mexicanos entered into an indenture with Deutsche Bank Trust Company Americas, as Trustee. This agreement provides for the issuance by Petróleos Mexicanos from time to time of unsecured debt securities. On the same date, Petróleos Mexicanos entered into a distribution agreement with Calyon Securities (USA) Inc., Citigroup Global Markets Inc., Citigroup Global Markets Limited, HSBC Securities (USA) Inc. and Santander Investment Securities Inc. pursuant to which Petróleos Mexicanos established a U.S. $7 billion medium-term note, Series C, program. Pursuant to the 1996 guaranty agreement referred to above, Petróleos Mexicanos’ obligations under all notes issued under this program are jointly and severally guaranteed by Pemex-Exploration and Production, Pemex-Refining and Pemex-Gas and Basic Petrochemicals. Petróleos Mexicanos issued approximately U.S. $6.1 billion of notes under this program in 2009. In January 2010, Petróleos Mexicanos increased the size of this program to U.S. $12 billion.

Exchange Controls

Mexico has had a free market for foreign exchange since 1991, and the Mexican Government has allowed the peso to float freely against the U.S. dollar since December 1994. PEMEX has no control over or influence on this exchange rate policy. The Mexican Government has announced that it does not intend to change its floating exchange rate policy, but there is no guarantee that the Mexican Government will not change this policy. See “Item 3—Key Information—Exchange Rates” and “Item 3—Key Information—Risk Factors—Considerations Related to Mexico.”

Taxation Generally

The following summary contains a description of the principal Mexican and U.S. federal income tax consequences of the ownership and disposition of the Registered Securities, but it does not purport to be a comprehensive description of all of the tax considerations that may be relevant to a decision to invest in, or dispose of, the Registered Securities.

This summary is based on the federal tax laws of Mexico and the United States in force on the date of this Form 20-F, including the provisions of the income tax treaty between the United States and Mexico together with related protocols (which are subject to change), and does not describe any tax consequences arising under the laws of any state or municipality in Mexico, the United States or any other jurisdiction, or the laws of any taxing jurisdiction other than the federal laws of Mexico and the United States.

Mexico has also entered into, or is negotiating, tax treaties with various countries that may have effects on holders of Registered Securities. This summary does not discuss the consequences (if any) of such treaties.

Each holder or beneficial owner of Registered Securities should consult its tax advisor as to the Mexican, United States or other tax consequences of the ownership and disposition of those securities, including the effect of any foreign, state or municipal tax laws, and the consequences of the application of any tax treaty to which Mexico is a party.

Mexican Taxation

This summary of certain Mexican federal tax considerations refers only to holders of Registered Securities that are not residents of Mexico for Mexican tax purposes and that will not hold the Registered Securities or a beneficial interest therein through a permanent establishment for tax purposes (we refer to any such non-resident holder as a Foreign Holder). For purposes of Mexican taxation, an individual is a resident of Mexico if he/she has established his/her domicile in Mexico. When an individual also has a place of residence in another country, that individual will be considered a resident of Mexico for tax purposes, if such individual has his/her center of vital interest in Mexico. An individual would be deemed to have his/her center of vital interest in Mexico if, among other things: (a) more than 50% of his/her total income for the year were derived from Mexican sources, or (b) his/her principal center of professional activities were located in Mexico.

181

A legal entity is a resident of Mexico if:

• it maintains the principal administration of its business in Mexico; or

• it has established its effective management in Mexico.

A Mexican national is presumed to be a resident of Mexico unless such person can demonstrate the contrary. If a legal entity or individual has a permanent establishment in Mexico, such permanent establishment shall be required to pay taxes in Mexico on income attributable to such permanent establishment in accordance with Mexican federal tax law.

Taxation of Interest. Under the Mexican Income Tax Law and rules issued by the SHCP applicable to PEMEX, payments of interest (which is deemed to include any amounts paid in excess of the original issue price of the relevant securities), made by a Mexican issuer (including Petróleos Mexicanos) in respect of notes or bonds and other debt securities to a Foreign Holder will generally be subject to a Mexican withholding tax assessed at a rate of 4.9%, if the following requirements are met:

• notice relating to the offering of such notes or bonds is given to the National Banking and Securities Commission as required under the Securities Market Law and evidence of such notice is timely filed with the SHCP;

• such notes or bonds are placed outside of Mexico through banks or brokerage houses in a country that has entered into a treaty to avoid double taxation with Mexico; and

• the issuer duly complies with the information requirements established in the general rules issued by the SHCP for such purposes.

If the effective beneficiaries, directly or indirectly, individually or jointly with related parties, receive more than 5% of the interest paid on such notes or bonds and are holders, directly or indirectly, individually or jointly, with related parties of more than 10% of the voting stock of the issuer or entities 20% or more of whose stock is owned directly or indirectly, individually or jointly, by parties related to the issuer, the withholding tax rate applicable to payment of interest on such notes or bonds may be significantly higher.

Payments of interest made by Petróleos Mexicanos, Pemex-Exploration and Production, Pemex-Refining or Pemex-Gas and Basic Petrochemicals in respect of the Registered Securities to non-Mexican pension or retirement funds will be exempt from Mexican withholding taxes, provided that:

• such fund is duly organized pursuant to the laws of its country of origin and is the effective beneficiary of the interest payment;

• the income from such interest payment is exempt from income tax in such country of residence; and

• such fund is registered with the SHCP for that purpose.

Additional Amounts. Petróleos Mexicanos, Pemex-Exploration and Production, Pemex-Refining and Pemex-Gas and Basic Petrochemicals have agreed, subject to specified exceptions and limitations, to:

• pay Additional Amounts (as defined in the indenture dated as of September 18, 1997, between Petróleos Mexicanos and Deutsche Bank (the 1997 Indenture)) to the holders of the 1997 Securities in respect of the Mexican withholding taxes mentioned above;

• pay Additional Amounts (as defined in the indenture dated as of August 7, 1998, between Petróleos Mexicanos and Deutsche Bank (the 1998 Indenture)) to the holders of the 1998 Securities in respect of the Mexican withholding taxes mentioned above;

• pay Additional Amounts (as defined in the indenture dated as of July 31, 2000, as supplemented, between Petróleos Mexicanos and Deutsche Bank) to the holders of the 2001 Securities, the 2003 Securities and the 2004 Securities in respect of the Mexican withholding taxes described above;

182

• pay Additional Amounts (as defined in the indenture dated as of December 30, 2004, as supplemented, between Petróleos Mexicanos and Deutsche Bank) to the holders of the 2006 Securities and the 2008 Securities in respect of the Mexican withholding taxes described above; and

• pay Additional Amounts (as defined in the indenture dated as of January 27, 2009, between Petróleos Mexicanos and Deutsche Bank) to the holders of the 2009 Securities in respect of the Mexican withholding taxes described above.

If Petróleos Mexicanos pays Additional Amounts in respect of such Mexican withholding taxes, any refunds received with respect to such Additional Amounts will be for the account of Petróleos Mexicanos.

Holders or beneficial owners of the Registered Securities may be requested to provide certain information or documentation necessary to enable Petróleos Mexicanos, Pemex-Exploration and Production, Pemex-Refining or Pemex-Gas and Basic Petrochemicals to establish the appropriate Mexican withholding tax rate applicable to such holders or beneficial owners. In the event that the specified information or documentation concerning such holder or beneficial owner, if requested, is not provided on a timely basis, the obligation of Petróleos Mexicanos, Pemex-Exploration and Production, Pemex-Refining or Pemex-Gas and Basic Petrochemicals to pay Additional Amounts may be limited.

Taxation of Dispositions. Capital gains resulting from the sale or other disposition of the Registered Securities by a Foreign Holder will not be subject to Mexican income or withholding taxes.

Other Mexican Tax Considerations. Under the Income Tax Law, any discount received by a non-resident upon purchase of the notes or bonds from a Mexican resident or a non-resident with a permanent establishment in Mexico is deemed interest income, and therefore, subject to taxes in Mexico. Such interest income results from the difference between the face value (plus accrued interest not subject to withholding) and the purchase price of such notes or bonds.

Transfer and Other Taxes. There are no Mexican stamp, registration or similar taxes payable by a Foreign Holder in connection with the purchase, ownership or disposition of the Registered Securities. A Foreign Holder of the Registered Securities will not be liable for Mexican estate, succession, gift, inheritance or similar tax with respect to such securities.

United States Taxation

This summary of certain U.S. federal income tax considerations deals principally with persons that hold the Registered Securities as capital assets and whose functional currency is the U.S. dollar. As used in this section “Taxation,” the term “United States Holder” means an individual who is a citizen or resident of the United States, a U.S. domestic corporation or any other person that is subject to U.S. federal income taxation on a net income basis in respect of its investment in the Registered Securities.

This summary does not purport to be a comprehensive description of all the tax considerations that may be relevant to any particular investor, including tax considerations that arise from rules of general application or that are assumed to be known to investors. This summary generally does not address the tax treatment of holders that may be subject to special tax rules, such as banks, insurance companies, tax-exempt organizations, dealers in securities or currencies, certain short-term holders of Registered Securities, traders in securities electing to mark to market, or persons that hedge their exposure in the Registered Securities or hold the Registered Securities as a position in a “straddle” for tax purposes or as part of a “synthetic security” or a “conversion transaction” or other integrated investment comprised of such securities and one or more other investments, nor does it address the tax treatment of holders that did not acquire the Registered Securities at their issue price as part of the initial distribution. Investors who purchased the Registered Securities at a price other than the issue price should consult their tax advisor as to the possible applicability to them of the amortizable bond premium or market discount

183

rules. United States Holders should be aware that the U.S. federal income tax consequences of holding the Registered Securities may be materially different for investors described in the prior sentence, including as a result of recent changes in law applicable to investors with short holding periods or that engage in hedging transactions.

Taxation of Interest and Additional Amounts. A United States Holder will treat the gross amount of interest and Additional Amounts (i.e., without reduction for Mexican withholding taxes) as ordinary interest income in respect of the Registered Securities. Mexican withholding taxes paid at the appropriate rate applicable to the United States Holder will be treated as foreign income taxes eligible, subject to generally applicable limitations and conditions, for credit against such United States Holder’s U.S. federal income tax liability, at the election of such United States Holder, or for deduction in computing such United States Holder’s taxable income, provided that the United States Holder does not elect to claim a foreign tax credit for any foreign income taxes paid or accrued for the relevant taxable year. Interest and Additional Amounts will constitute income from sources without the United States and generally will be treated separately along with other items of “passive” income for purposes of determining the credit for foreign income taxes allowed under the Internal Revenue Code of 1986, as amended.

The calculation and availability of foreign tax credits or deductions involves the application of rules that depend on a United States Holder’s particular circumstances. United States Holders should consult their own tax advisors regarding the availability of foreign tax credits and the treatment of Additional Amounts.

Foreign tax credits may not be allowed for withholding taxes imposed in respect of certain short-term or hedged positions in securities or in respect of arrangements in which a United States Holder’s expected economic profits is insubstantial. United States Holders should consult their own advisors concerning the implications of these rules in light of their particular circumstances.

Taxation of Dispositions. Upon the sale, exchange or retirement of a Registered Security, a United States Holder will generally recognize a gain or loss equal to the difference between the amount realized (less any amounts attributable to accrued and unpaid interest not previously includible in gross income, which will be taxable as ordinary income) and the holder’s tax basis in such security. Gain or loss recognized by a United States Holder on the sale, redemption or other disposition of the Registered Securities generally will be long-term capital gain or loss if, at the time of disposition, the securities have been held for more than one year. Long-term capital gain realized by an individual United States Holder is generally taxed at lower rates than short-term capital gains or ordinary income.

Non-United States Holders. Holders of the Registered Securities that are, with respect to the United States, non-resident aliens or foreign corporations (which we refer to as Non-United States Holders) will not be subject to U.S. federal income taxes, including withholding taxes, on payments of interest on the securities so long as the requirements described under “Backup Withholding and Information Reporting” are satisfied, unless such income is effectively connected with the conduct by the Non-United States Holder of a trade or business in the United States.

The gain realized on any sale or exchange of the Registered Securities by a Non-United States Holder will not be subject to U.S. federal income tax, including withholding tax, unless (1) such gain is effectively connected with the conduct by the holder of a trade or business in the United States or (2) in the case of gain realized by an individual holder, the holder is present in the United States for 183 days or more in the taxable year of the sale and either (A) such gain or income is attributable to an office or other fixed place of business maintained in the United States by such holder or (B) such holder has a tax home in the United States.

A Registered Security held by an individual holder who at the time of death is a non-resident alien will not be subject to U.S. federal estate tax.

184

Backup Withholding and Information Reporting. The principal paying agent for each of the Registered Securities will be required to file information returns with the Internal Revenue Service with respect to payments made to certain United States Holders of those securities. In addition, certain United States Holders may be subject to a backup withholding tax in respect of such payments, unless they (1) provide their accurate taxpayer identification numbers to the principal paying agent and certify that they are not subject to backup withholding or (2) otherwise establish an exemption from the backup withholding tax. Non-United States Holders may be required to comply with applicable certification procedures to establish that they are not United States Holders in order to avoid the application of such information reporting requirements and backup withholding tax.

Item 11. Quantitative and Qualitative Disclosures about Market Risk

Risk Management and Financial Instruments

PEMEX faces market risks caused by the volatility of hydrocarbon prices, exchange rates and interest rates. In order to monitor and manage these risks, Petróleos Mexicanos and the subsidiary entities have developed regulations relating to market risk management, which are comprised of policies and guidelines applicable to Petróleos Mexicanos and the subsidiary entities that promote an integrated scheme for market risk management, regulate the use of DFIs, guide the development of hedging strategies and provide strategies for the formulation of risk limits.

Risk management regulations of Petróleos Mexicanos and the subsidiary entities establish that DFIs should generally be used only for the purpose of hedging. The use of DFIs for any other purpose must be approved in accordance with PEMEX’s internal procedures.

Petróleos Mexicanos and the subsidiary entities have a policy of reducing the impact of market risk on their financial results by promoting a balance between expected incoming cash flows from operations and outgoing cash flows relating to their liabilities.

Finally, the PMI Group has implemented separate policies for risk management, based on their “General Guidelines for Risk Management,” and which contains procedures and instructions to ensure the realization of essential risk controls, in accordance with industry best practices, such as generation of a periodic portfolio risk report for risk takers and management. The PMI Group also has its own internal audit unit and a risk management subcommittee.

Hydrocarbon Price Risk

Petróleos Mexicanos and the subsidiary entities periodically evaluate their exposure to international hydrocarbon prices and use DFIs as a mechanism to mitigate identified potential sources of risk.

Since 2003, PEMEX has been required to trade LPG under a price scheme imposed by the Mexican Government. This scheme fixes the sale price of LPG throughout Mexico and generates a risk exposure in the geographic areas where PEMEX sells imported LPG. During 2009, PEMEX mitigated the market risk generated by this exposure by employing a hedging strategy consisting of propane swaps. Propane is the primary component of LPG.

185

P.M.I. Trading, Ltd. periodically enters into DFIs to mitigate risk generated in the purchase and sale of refined products and liquid gas, thereby reducing the potential volatility of its income. P.M.I. Trading, Ltd. policies establish an upper limit for capital at risk, which is compared on a daily basis with the value-at-risk portfolio in order to execute risk mitigation mechanisms if necessary.

We did not hedge any of our crude oil production for the years 2006, 2007, 2008 or 2009.

Exchange Rate and Interest Rate Risks

Exchange Rate Risk

A significant amount of our revenues is derived from exports of crude oil and petroleum products, which are priced and payable in U.S. dollars. Moreover, our revenues net of the IEPS tax from domestic sales of petroleum products and petrochemicals are related to the international dollar-denominated prices of these products. By contrast, most of our costs of sales and other expenses, other than hydrocarbon duties and investment expenditures, are payable in pesos and are not linked to the U.S. dollar. As a result, the peso’s depreciation against the U.S. dollar increases our income in peso terms. Appreciation of the peso relative to the U.S. dollar has the opposite effect. We perceive this risk as manageable, without the need for hedging instruments, because most of our investments and debt issuances are made in U.S. dollars and therefore, the impact of the fluctuation in the exchange rate between the U.S. dollar and the peso on our revenues is offset by its impact on our obligations.

Cross-Currency Swaps

Most of our debt is denominated in U.S. dollars or pesos. However, we borrow in currencies other than the peso or the U.S. dollar. Therefore, fluctuations in non-dollar currencies (other than pesos) can increase our costs of funding. Since 1991, we have entered into currency swaps to hedge against movements in exchange rates when we borrow in currencies other than pesos and U.S. dollars.

In 2009, we entered into various cross-currency swaps to hedge currency risk arising from debt obligations denominated in euros, pounds, and Swiss francs for an aggregate notional amount of U.S. $2,667.7 million.

During the first five months of 2010, we entered into further cross-currency swaps whose aggregate notional amounts as of May 31, 2010 were U.S. $139.7 million and Ps. 3,540.2 million.

As described above, most of our revenues are either in U.S. dollars or indexed to the U.S. dollar and our policy for debt issuances is either to issue debt in pesos or U.S. dollars or to swap debt issued in other currencies back to U.S. dollar terms, or, in the case of debt denominated in UDIs, to pesos. As a result of this policy, we believe that our debt portfolio’s sensitivity to currencies other than the peso and U.S. dollar is negligible.

In 2002 and 2004, the Master Trust entered into cross-currency swaps to hedge its exposure in Japanese yen and euros, with termination dates in 2023 and 2016. Given the long-term nature of these obligations, the swaps used to hedge these risks include an option linked to a well-defined set of credit default events. In case such an event occurs, the swaps terminate without any payment obligation by either party. These swaps have a notional amount of U.S. $241.4 million and U.S. $1,028.5 million, respectively.

We recorded total net foreign exchange losses in the comprehensive financing cost item of Ps. 1,435 million and Ps. 71,063 million in 2007 and 2008, respectively, and total net foreign exchange gains in this item of Ps. 14,685 million in 2009. The significant increase in our foreign exchange losses in 2008 was due to the effect of the depreciation of the peso on the value in pesos of our U.S. dollar-denominated debt. Our foreign exchange gains recorded in 2009 were primarily the result of the appreciation of the Mexican peso against the U.S. dollar, which resulted in the opposite effect on the value of such debt.

186

Interest Rate Risk

We are exposed to fluctuations in interest rates on short- and long-term floating rate instruments. We are predominantly exposed to U.S. dollar LIBOR interest rates because, as discussed above, our borrowings are primarily denominated in, or swapped into, U.S. dollars. We use derivative instruments as described below to achieve a desired mix of fixed and floating rate instruments in our debt portfolio. As of December 31, 2009, approximately 42.4% of our total net debt outstanding consisted of floating rate debt.

Interest Rate Swaps

Under interest rate swap agreements, we are obligated to make payments based on a fixed interest rate and are entitled to receive payments based on either the floating six-month LIBOR, for U.S. dollar-denominated swaps, or the Mexican Interbank Interest Rate (TIIE) for peso-denominated swaps. Some interest rate swaps have as their underlying rate, not the TIIE, but a rate referenced to or calculated from the TIIE. As of December 31, 2009, we were a party to interest rate swap agreements for a notional amount of U.S. $1,135.2 million, an average fixed interest rate of approximately 4.94% in U.S. dollars and 11.36% in pesos, respectively, and a weighted average term of approximately 3.0 years. In 2008, 2009 and the first five months of 2010, we did not enter into any new interest rate swap agreements.

The market value of our foreign exchange, equity and interest rate derivatives position was Ps. (2,018.8 million) as of December 31, 2008, and Ps. 8,511.7 million as of December 31, 2009.

The effects on the consolidated statements of income of entering into swap transactions designated as hedges are recorded as incurred, and when the precise settlement amounts are known. The effects on the consolidated statements of income of derivative instruments not designated as hedges are recognized in earnings according to changes in their fair value. Such amounts are included in the consolidated statements of income within the “Interest, Net” caption. See Note 11 to our consolidated financial statements included herein.

Credit Risk

When the fair value of DFIs is favorable to PEMEX, we face the risk that counterparties will not be able to meet their obligations. To reduce this risk, we monitor our counterparties’ creditworthiness and credit exposure risk in our DFIs. During 2009, we entered into various long-term cross-currency swap agreements containing recouponing provisions for hedging purposes, thereby limiting our exposure with our counterparties to a specific threshold amount. Additionally, we enter into agreements mostly with major financial institutions and maintain a diversified portfolio.

Instruments Entered into for Trading Purposes

We enter into derivative transactions with the purpose of hedging financial risks related to our operations, assets or liabilities. Nonetheless, some of these transactions do not qualify for accounting treatment as hedges and are recorded in our financial statements as entered into for trading purposes, despite the fact that the profits or losses are offset by the profits or losses of the positions to which they relate.

Petróleos Mexicanos retains a synthetic long position on 58,679,799 shares of Repsol YPF, with the objective of maintaining corporate rights over these shares. This is accomplished by using four total return swaps under which Petróleos Mexicanos pays fixed amounts and receives total return on Repsol shares. Two of the aforementioned DFIs contain an option structure comprised of one short call and one long put spread.

Pemex-Gas and Basic Petrochemicals offers DFIs to its domestic customers to help them mitigate the risk associated with natural gas prices. Through its subsidiary, MGI Supply Ltd., Pemex-Gas and Basic Petrochemicals enters into DFIs with the position opposite those DFIs it offers to its customers, in order to cancel

187

out the market risk it bears under such offered DFIs. MGI Supply Ltd. enters into these opposite position DFIs with international counterparties, in order to transfer the related price risk to such parties. This system allows Pemex-Gas and Basic Petrochemicals to maintain overall its natural risk profile. Because neither Bulletin C-10 nor ASC Topic 815 “Derivatives and Hedging” allows derivative positions to serve as hedges for other derivatives, these operations are treated, for accounting purposes, as having been entered into for trading purposes.

The following tables set forth our portfolio of debt and DFIs as of December 31, 2009. It should be noted that:

• for debt obligations, this table presents principal cash flows and related weighted average interest rates for fixed rate debt;

• for interest rate and currency swaps, this table presents notional amounts and weighted average interest rates by expected (contractual) maturity dates;

• for natural gas DFIs, volumes are presented in millions of British thermal units (MMBtu), and average fixed and strike prices are presented in U.S. dollars per MMBtu;

• weighted average variable rates are based on implied forward rates in the yield curve at the reporting date;

• fair values are obtained from market quotes received from market sources such as Reuters and Bloomberg;

• where quotes are not available, fair value is calculated internally, discounting from the corresponding zero coupon yield curve in the original currency;

• for all instruments, the tables show the contract terms in order to determine future cash flows categorized by expected maturity dates;

• the information is presented in equivalents of the peso, which is our reporting currency; and

• each instrument’s actual cash flows are denominated in U.S. dollars or other foreign currencies as indicated in parentheses.

Item 14. Material Modifications to the Rights of Security Holders and Use of Proceeds

Not applicable.

Item 15. Controls and Procedures

(a) Disclosure Controls and Procedures

We carried out an evaluation under the supervision and with the participation of our management, including our Director General and our chief financial officer, of the effectiveness of the design and operation of our disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) of the Exchange Act) as of December 31, 2009. There are inherent limitations to the effectiveness of any system of disclosure controls and procedures, including the possibility of human error and the circumvention or overriding of the controls and procedures. Accordingly, effective disclosure controls and procedures can provide only reasonable assurance of achieving their control objectives.

Based upon our evaluation, our Director General and our chief financial officer concluded that our disclosure controls and procedures as of December 31, 2009 were effective to provide reasonable assurance that information required to be disclosed in the reports we file and submit under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms, and that such information is accumulated and communicated to our management, including our Director General and our chief financial officer, as appropriate, to allow timely decisions regarding required disclosures.

(b) Management’s annual report on internal control over financial reporting

Management is responsible for establishing and maintaining adequate internal control over financial reporting as defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act. Our internal control over financial reporting is designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with Mexican FRS. Our internal control over financial reporting includes those policies and procedures that:

(1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of PEMEX;

(2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with Mexican FRS, including the reconciliation to U.S. GAAP in accordance with Item 18 of Form 20-F, and that receipts and expenditures of PEMEX are being made only in accordance with authorizations of management and directors of the relevant entity; and

(3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use or disposition of PEMEX’s assets that could have a material effect on our financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

Management assessed the effectiveness of PEMEX’s internal control over financial reporting as of December 31, 2009. In making this assessment, management used the criteria set forth by the Committee of

193

Sponsoring Organizations of the Treadway Commission (COSO) in its Internal Control-Integrated Framework and the Control Objectives for Information and Related Technology (COBIT) created by the IT Governance Institute.

Management relied on Auditing Standards No. 2 and 5 of the PCAOB (as defined below) in order to create an appropriate framework to evaluate the effectiveness of the design and operation of PEMEX’s internal control over financial reporting.

Based on our assessment and those criteria, management concluded that PEMEX maintained effective internal control over financial reporting as of December 31, 2009.

(4) The effectiveness of our control over financial reporting as of December 31, 2009 has been audited by KPMG Cárdenas Dosal, S.C., our independent registered public accounting firm, as stated in their attestation report dated as of June 28, 2010, which appears below in Item 15(c) (Attestation Report of the Independent Registered Public Accounting Firm).

(c) Attestation report of the independent registered public accounting firm

Report of Independent Registered Public Accounting Firm

To the General Comptroller’s Office

and the Board of Directors of

Petróleos Mexicanos

We have audited the internal control over financial reporting of Petróleos Mexicanos as of December 31, 2009, based on criteria established in Internal Control-Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). Petróleos Mexicanos’ management is responsible for maintaining effective internal control over financial reporting, and for its assessment of the effectiveness of internal control over financial reporting included in the accompanying Management’s Annual Report on Internal Control Over Financial Reporting. Our responsibility is to express an opinion on the Petróleos Mexicanos’ internal control over financial reporting based on our audit.

We conducted our audit in accordance with the standards of the Public Company Accounting Oversight Board (which we refer to as the PCAOB). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects. Our audit included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists and testing and evaluating the design and operating effectiveness of internal control based on the assessed risk. Our audit also included performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion.

A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that: (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of consolidated financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

194

In our opinion, Petróleos Mexicanos maintained, in all material respects, effective internal control over financial reporting as of December 31, 2009, based on criteria established in Internal Control-Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission.

We also have audited, in accordance with the standards issued by the PCAOB and with auditing standards generally accepted in Mexico, the consolidated balance sheets of Petróleos Mexicanos, Subsidiary Entities and Subsidiary Companies as of December 31, 2009 and 2008, and the related consolidated statements of operations, changes in equity for each of the years in the three year period ended December 31, 2009, the related consolidated statements of cash flows for the two-year period ended December 31, 2009 and the related consolidated statement of changes in financial position for the year ended December 31, 2007, and our report dated June 28, 2010 expressed an unqualified opinion on those consolidated financial statements.

We have audited the accompanying consolidated balance sheets of Petróleos Mexicanos, Subsidiary Entities and Subsidiary Companies (“PEMEX”) as of December 31, 2009 and 2008, and the related consolidated statements of operations and changes in equity for each of the years in the three-year period ended December 31, 2009, the related consolidated statements of cash flows for the years ended December 31, 2009 and 2008; and the related consolidated statement of changes in financial position for the year ended December 31, 2007. These consolidated financial statements are the responsibility of the management of PEMEX. Our responsibility is to express an opinion on these consolidated financial statements based on our audits.

We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States) and with auditing standards generally accepted in Mexico. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion.

In our opinion, the consolidated financial statements referred to above present fairly, in all material respects, the financial position of Petróleos Mexicanos, Subsidiary Entities and Subsidiary Companies as of December 31, 2009 and 2008, and the results of their operations for each of the years in the three-year period ended December 31, 2009, the results of their cash flows for the years ended December 31, 2008 and 2009; and the changes in their financial position for the year ended December 31, 2007, in conformity with Mexican Financial Reporting Standards.

As disclosed in note 3 (y) to the consolidated financial statements, on January 1, 2008, PEMEX adopted the FRS B-2 “Statement of Cash Flows”, FRS B-10 “Effect of Inflation”, FRS B-15 “Translation of Foreign Currencies”, D-3 “Employee Benefits” and D-4 “Taxes on Profit”.

Mexican Financial Reporting Standards vary in certain significant respects from U.S. generally accepted accounting principles. Information relating to the nature and effect of such differences is presented in note 21 to the consolidated financial statements.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), Petróleos Mexicanos’ internal control over financial reporting as of December 31, 2009, based on criteria established in Internal Control-Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO), and our report dated June 28, 2010, expressed an unqualified opinion on the effectiveness of the Petróleos Mexicanos’ internal control over financial reporting.

The final consolidated financial statements were authorized for issuance herein by Public Accountant Víctor M. Cámara Peón, Deputy Director of Financial Information Systems, and Public Accountant Enrique Díaz Escalante, Associate Managing Director of Accounting, on June 28, 2010, as updated to consider subsequent events, including those related to Notes 16 and 20, through such date.

NOTE 2—STRUCTURE AND BUSINESS OPERATIONS OF PETRÓLEOS MEXICANOS, SUBSIDIARY ENTITIES AND SUBSIDIARY COMPANIES:

Petróleos Mexicanos was created on June 7, 1938, and began operations on July 20, 1938 in accordance with a decree of the Mexican Congress stating that all foreign-owned oil companies in operation at that time in the United Mexican States (“Mexico”) were thereby nationalized. Petróleos Mexicanos and its four Subsidiary Entities (as defined below) are decentralized public entities of the Federal Government of Mexico (the “Mexican Government”) and together comprise the Mexican oil and gas industry.

The operations of Petróleos Mexicanos and its Subsidiary Entities are regulated by the Constitución Política de los Estados Unidos Mexicanos (Political Constitution of the United Mexican States, or the “Mexican Constitution”), the Ley Reglamentaria del Artículo 27 Constitucional en el Ramo del Petróleo (Regulatory Law to Article 27 of the Political Constitution of the United Mexican States concerning Petroleum Affairs, or the “Regulatory Law”), effective on November 29, 2008, which establishes that the State will be exclusively entrusted with the activities in the strategic areas of petroleum, hydrocarbons and basic petrochemicals through Petróleos Mexicanos and its Subsidiary Entities in accordance with the Regulatory Law and its regulations pursuant to which Petróleos Mexicanos is entitled to exercise control over the management and strategic direction of the business.

On November 28, 2008, amendments to the following laws were published in the Diario Oficial de la Federación (Official Gazette of the Federation):

• the Regulatory Law;

• the Ley Orgánica de la Administración Pública Federal (Federal Public Administration Organic Law);

• the Ley de la Comisión Reguladora de Energía (Energy Regulatory Commission Law); and

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS—(Continued)

FOR THE YEARS ENDED DECEMBER 31, 2009, 2008 AND 2007

(Figures stated in thousands of Mexican pesos, except as noted)

• the Ley Federal de las Entidades Paraestatales (Federal Law of Decentralized Public Entities).

On that same date, the following new laws were issued:

• the Petróleos Mexicanos Law, which replaced the Ley Orgánica de Petróleos Mexicanos y Organismos Subsidiarios (Organic Law of Petróleos Mexicanos and the Subsidiary Entities);

• the Ley de la Comisión Nacional de Hidrocarburos (National Hydrocarbons Commission Law);

• the Ley para el Aprovechamiento de Energías Renovables y el Financiamiento de la Transición Energética (Law of Use of Renewable Energy and Financing of the Energy Transition); and

• the Ley para el Aprovechamiento Sustentable de la Energía (Sustainable Use of Energy Law).

This new legal framework, among other aspects, includes changes in the structure of the Board, the development of specific contracting procedures for substantive production activities, increased flexibility to invest excess funds generated through surplus income, a differentiated fiscal regime that takes into consideration the complexity of crude oil and natural gas fields and the ability to issue bonos ciudadanos (Citizen Bonds).

In addition, on November 13, 2008, amendments to the Federal Law of Budget and Fiscal Accountability were published in the Official Gazette of the Federation. The principal effects of these amendments were the following:

• Elimination of the Proyectos de Infraestructura Productiva de Largo Plazo (long-term productive infrastructure projects, or “PIDIREGAS”) legal framework. On January 1, 2009, Norma Específica de Información Financiera Gubernamental para el Sector Paraestatal (Specific Standard for Governmental Financial Information of the State-owned Sector, or “NEIFGSP”) 009 (“NEIFGSP 009”) was declared ineffective, pursuant to which, PEMEX (as defined below) immediately was required to recognize the investments and related liabilities for which it had contracted, thereby eliminating one of the principal differences between NEIFGSP and Mexican FRS.

• As of January 31, 2009, PEMEX recognized as direct public debt, for accounting and budgeting purposes, all financings relating to PIDIREGAS.

• As of December 31, 2009, PEMEX formally recognized, as direct public debt, all obligations derived from PIDIREGAS-related financings that had been entered into by the Pemex Project Funding Master Trust (the “Master Trust”) and Fideicomiso Irrevocable de Administración No. F/163 (“Fideicomiso F/163”).

In September 2009, new regulations to the Reglamento de la Ley de Petróleos Mexicanos (Regulations to the Petróleos Mexicanos Law) and to the Reglamento de la Ley Reglamentaria del Artículo 27 Constitucional en el Ramo del Petróleo (Regulations to the Regulatory Law to Article 27 of the Political Constitution of the United Mexican States concerning Petroleum Affairs, or the “Regulations”) were published. These new regulations regulate the application of the Petróleos Mexicanos Law and relate to the oversight of Petróleos Mexicanos and its Subsidiary Entities, as well as their relationship with the Mexican Government, respectively.

In addition, on September 4, 2009, the Board approved the Estatuto Orgánico de Petróleos Mexicanos (Organic Statute of Petróleos Mexicanos), which establishes the structure, organizational basis and functions of the administrative units of Petróleos Mexicanos, and also delineates the internal regulations and powers of the Board. The Organic Statute of Petróleos Mexicanos became effective as of September 25, 2009.

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS—(Continued)

FOR THE YEARS ENDED DECEMBER 31, 2009, 2008 AND 2007

(Figures stated in thousands of Mexican pesos, except as noted)

Petróleos Mexicanos’ purpose is the exploration, exploitation and other activities mentioned above, as well as the central business management and strategic direction of Mexico’s petroleum industry, in accordance with the Petróleos Mexicanos Law.

Petróleos Mexicanos may rely on decentralized Subsidiary Entities to carry out the activities that constitute the petroleum industry. The Petróleos Mexicanos Law establishes that the four Subsidiary Entities (as listed below) will continue carrying out their activities in accordance with their objectives, guaranteeing the commitments they have already assumed in Mexico and abroad, until the Mexican Government issues the corresponding decrees of reorganization based on a proposal by the Board.

The Subsidiary Entities are decentralized public entities of a technical, industrial and commercial nature with their own corporate identity and equity and with the legal authority to own property and conduct business in their own names. The Subsidiary Entities are controlled by and have the characteristics of subsidiaries of Petróleos Mexicanos. The Subsidiary Entities are:

• Pemex-Exploración y Producción (“Pemex-Exploration and Production”);

• Pemex-Refinación (“Pemex-Refining”);

• Pemex-Gas y Petroquímica Básica (“Pemex-Gas and Basic Petrochemicals”); and

• Pemex-Petroquímica (“Pemex-Petrochemicals”).

The strategic activities entrusted to Petróleos Mexicanos and the Subsidiary Entities, other than those entrusted to Pemex-Petrochemicals, can be performed only by Petróleos Mexicanos and the Subsidiary Entities and cannot be delegated or subcontracted. Pemex-Petrochemicals is an exception and may delegate and/or subcontract certain of its entrusted activities.

The principal objectives of the Subsidiary Entities are as follows:

I. Pemex-Exploration and Production explores for and produces crude oil and natural gas; additionally, this entity transports, stores and markets such products;

II. Pemex-Refining refines petroleum products and derivatives thereof that may be used as basic industrial raw materials; additionally, this entity stores, transports, distributes and markets such products and derivatives;

III. Pemex-Gas and Basic Petrochemicals processes natural gas, natural gas liquids and derivatives thereof that may be used as basic industrial raw materials, and stores, transports, distributes and markets such products; additionally, this entity stores, transports, distributes and markets basic petrochemicals; and

IV. Pemex-Petrochemicals engages in industrial petrochemical processing of products that do not form part of the basic petrochemicals industry, as well as stores, distributes and markets these products.

Petróleos Mexicanos assigned to the Subsidiary Entities all the assets and liabilities needed to carry out these activities; these assets and liabilities were incorporated into the Subsidiary Entities’ initial capital contribution. Additionally, Petróleos Mexicanos assigned to the Subsidiary Entities all the personnel needed for their operations, and the Subsidiary Entities assumed all the related labor liabilities. There were no changes in the carrying value of assets and liabilities upon their contribution by Petróleos Mexicanos to the Subsidiary Entities.

For purposes of these consolidated financial statements, any capitalized word that is not defined herein will have the meaning attributed to it in the Regulatory Law or in the Petróleos Mexicanos Law.

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS—(Continued)

FOR THE YEARS ENDED DECEMBER 31, 2009, 2008 AND 2007

(Figures stated in thousands of Mexican pesos, except as noted)

The principal distinction between the Subsidiary Entities and the Subsidiary Companies (as defined below) is that the Subsidiary Entities are decentralized public entities created by the Organic Law of Petróleos Mexicanos and the Subsidiary Entities, whereas the Subsidiary Companies are companies that have been formed in accordance with the applicable laws of each of the respective jurisdictions in which they have been incorporated, and are managed in the same way as any other private corporations subject to the laws and regulations of their respective jurisdictions.

As used herein, the “Subsidiary Companies” are defined as (a) those companies which are not the Subsidiary Entities but in which Petróleos Mexicanos has more than 50% ownership investment and effective control, (b) the Master Trust, a Delaware statutory trust, (c) Fideicomiso F/163, a Mexican statutory trust incorporated in 2003 in Mexico (both the Master Trust and Fideicomiso F/163 are controlled by Petróleos Mexicanos), (d) RepCon Lux, S.A. (“RepCon Lux”), a Luxembourg finance vehicle whose debt is guaranteed by Petróleos Mexicanos, and (e) Pemex Finance, Ltd. (see Note 3(b)).

“Non-consolidated subsidiary companies,” as used herein, means (a) those non-material subsidiary companies which are not Subsidiary Entities or Subsidiary Companies, as defined above in this Note, and (b) those companies in which PEMEX (as defined below) has 50% or less ownership investment and does not have effective control.

Petróleos Mexicanos, the Subsidiary Entities and the Subsidiary Companies are referred to collectively herein as “PEMEX.”

NOTE 3—SIGNIFICANT ACCOUNTING POLICIES:

The preparation of the financial statements requires the use of estimates and assumptions made by PEMEX’s management that affect the recorded amounts of assets and liabilities and the disclosures of contingent assets and liabilities as of the date of the consolidated financial statements, as well as the recorded amounts of income and expenses during the year. The important items subject to such estimates and assumptions include the carrying value of properties, plant and equipment, the valuation of the allowance for doubtful accounts, inventories, work in progress, deferred tax assets and liabilities, and the valuation of financial instruments and liabilities related to employee benefits. Actual results could differ from those estimates and assumptions.

In these consolidated financial statements and the related notes, “pesos” or “Ps.” refers to Mexican pesos, “U.S. dollars” or “U.S. $” refers to dollars of the United States of America, “yen” or “¥” refers to Japanese yen, “euros” or “€” refers to the legal currency of the European Economic and Monetary Union, “Pounds sterling” or “£” refers to the legal currency of the United Kingdom and “Swiss francs” or “CHF” refers to Swiss francs. Figures in all currencies are presented in thousands of the relevant currency unit, except exchange rates and product prices.

The U.S. dollar amounts shown in the consolidated balance sheets, the consolidated statements of operations, the consolidated statements of changes in equity and the consolidated statements of cash flows have been included solely for the convenience of the reader and are unaudited. Such amounts have been translated from amounts in pesos, as a matter of arithmetic computation only, at the exchange rate for the settlement of obligations in foreign currencies provided by Banco de México and the Secretaría de Hacienda y Crédito Público (Ministry of Finance and Public Credit, or the “SHCP”) at December 31, 2009 of 13.0587 pesos per U.S. dollar. Translations herein should not be construed as a representation that the peso amounts have been or could be converted into U.S. dollars at the foregoing or any other rate.

For accounting purposes the functional currency of PEMEX is the Mexican peso.

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS—(Continued)

FOR THE YEARS ENDED DECEMBER 31, 2009, 2008 AND 2007

(Figures stated in thousands of Mexican pesos, except as noted)

Below is a summary of the principal accounting policies followed by PEMEX in the preparation of these consolidated financial statements:

(a) Effects of inflation on the financial information

PEMEX recognizes the effects of inflation on its financial information in accordance with FRS B-10 “Effects of Inflation” (“FRS B-10”).

These consolidated financial statements include recognition of the effects of inflation on the financial information until December 31, 2007, based on the Mexican National Consumer Price Index (“NCPI”) issued by Banco de México. In accordance with FRS B-10, in 2008 and 2009, effects of inflation were not recognized in the financial statements because the accumulated inflation over the three-year periods ended December 31, 2008 and 2009 was less than 26%, and the economic environment therefore did not qualify as “inflationary.”

If at the end of the year in future years the accumulated inflation over the most recent three-year period were to be equal to or higher than 26%, the economic environment would be considered “inflationary,” and PEMEX would therefore be required to retroactively recognize the effects of inflation not previously included in its financial statements while the economic environment was considered non-inflationary.

The indexes used for the recognition of inflation were as follows:

December 31,	Inflation
	NCPI	For the year		Accumulated
2009	138.5410	3.57	%	14.48	%
2008	133.7610	6.52	%	15.01	%
2007	125.5640	3.76	%	11.56	%

(b) Consolidation

The consolidated financial statements include the accounts of Petróleos Mexicanos, the Subsidiary Entities and the Subsidiary Companies. All significant intercompany balances and transactions have been eliminated in the consolidation, and the consolidation has been made based on the audited financial statements of the Subsidiary Companies as of December 31, 2009 and 2008.

The consolidated Subsidiary Companies are as follows: P.M.I. Comercio Internacional, S.A. de C.V. (“PMI CIM”); P.M.I. Trading, Ltd. (“PMI Trading”); P.M.I. Holdings North America, Inc. (“PMI HNA”); P.M.I. Holdings Petróleos España, S.L. (“PMI HPE”); P.M.I. Holdings, B.V. (“PMI HBV”); P.M.I. Norteamérica, S.A. de C.V. (“PMI NASA”); Kot Insurance Company, AG (“KOT”); Integrated Trade Systems, Inc. (“ITS”); P.M.I. Marine, Ltd. (“PMI Mar”); P.M.I. Services, B.V. (“PMI-SHO”); Pemex Internacional España, S.A. (“PMI-SES”); Pemex Services Europe, Ltd. (“PMI-SUK”); P.M.I. Services North America, Inc. (“PMI-SUS”); Mex Gas International, Ltd. (“MGAS”); the Master Trust (i.); Fideicomiso F/163 (i.); RepCon Lux (ii.) and Pemex Finance, Ltd.

i. The principal function of the Master Trust and Fideicomiso F/163 (the “Trusts”) consisted of issuing bonds and entering into other financings for the purpose of funding PIDIREGAS. As discussed in Note 2, amendments to the Law of Budget and Fiscal Accountability published in the Official Gazette of the Federation on November 13, 2008 prohibited PEMEX from continuing to apply the PIDIREGAS framework. Therefore, during 2009, the Trusts transferred all of the rights and obligations derived from PIDIREGAS financings to PEMEX, which recognized them as direct public debt, while the Trusts

PETRÓLEOS MEXICANOS, SUBSIDIARY ENTITIES AND SUBSIDIARY COMPANIES

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS—(Continued)

FOR THE YEARS ENDED DECEMBER 31, 2009, 2008 AND 2007

(Figures stated in thousands of Mexican pesos, except as noted)

ceased to act as financing vehicles. Consequently, the continued existence of the Trusts will depend on decisions taken by PEMEX’s management. The changes described here have had no impact on the financial information, since the Trusts have been consolidated in the financial statements of PEMEX.

ii. Historically, PEMEX has consolidated the financial information of RepCon Lux pursuant to an administration contract with that company. Under the terms of that contract, PEMEX had the right to veto resolutions adopted by RepCon Lux’s board of directors if such resolutions were against PEMEX’s interest, or related to the issuance of bonds exchangeable for shares of Repsol (see Note 8). The contract provided for termination if RepCon Lux were to dissolve, and on July 28, 2009, RepCon Lux was formally liquidated. Therefore, as of such date, RepCon Lux has no longer been consolidated in the financial statements of PEMEX.

(c) Translation of foreign currency financial statements

Effective January 1, 2008 the financial statements of consolidated foreign subsidiaries are translated into the reporting currency by initially determining if the functional currency and the currency for recording the foreign operations are different and then translating the functional currency to the reporting currency, using the historical exchange rate or the exchange rate at year end and the inflation index of the country of origin, depending on whether the inflation derives from a non-inflationary or an inflationary economy.

(d) Cash and cash equivalents

Cash and cash equivalents consist of checking accounts, foreign currency and other highly liquid instruments. As of the date of these consolidated financial statements, earned interest income and foreign exchange gains or losses are included in the results of operations, under comprehensive financing result (“CFR”).

(e) Inventories and cost of sales

Inventories are valued as follows:

I. Crude oil, refined products, derivatives and petrochemicals are valued at the lowest of their production, acquisition or market costs.

II. Materials, spare parts and fixtures are valued at their average acquisition cost and are presented net of an allowance for slow-moving and obsolete materials.

III. Materials in transit are valued at their acquisition cost.

PEMEX records the necessary allowance for inventory impairment arising from obsolescence, slow-moving inventory and other factors that may indicate that the realization value of inventory may be lower than the recorded value.

Cost of sales is determined by adding to inventories at the beginning of the year the operating cost of oil fields, refineries and plants (including internally-consumed products) and the purchase cost of refined and other products, then deducting the value of inventories at the end of the year. Until December 31, 2007, the result of this calculation was adjusted for inflation based on factors derived from the NCPI. Cost of sales also includes the depreciation and amortization expense associated with assets used in operations, as well as the expense associated with the reserve for abandonment cost of wells.

(f) Investment in shares of non-consolidated subsidiary companies and affiliates

Investments in shares of non-consolidated subsidiary companies are valued by the equity method, based on the unaudited financial statements of the issuing companies as of December 31, 2009 and 2008. Other

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS—(Continued)

FOR THE YEARS ENDED DECEMBER 31, 2009, 2008 AND 2007

(Figures stated in thousands of Mexican pesos, except as noted)

non-consolidated affiliates and subsidiary companies were recorded at their acquisition cost, and based on their insignificance relative to the total assets and revenues of PEMEX, have been neither consolidated nor valued by the equity method. Until December 31, 2007, these companies were adjusted for inflation using factors derived from the NCPI.

(g) Long-term productive infrastructure projects (PIDIREGAS)

Until December 31, 2008, PIDIREGAS investments and related liabilities were recorded for accounting purposes in accordance with NEIFGSP 009 applicable to Entidades Paraestatales de la Administración Pública Federal (“State-owned Entities of the Federal Public Administration”), which provided that only liabilities maturing within two years should be recognized. In addition to establishing specific accounting treatment, NEIFGSP 009 identified specific legal and budgetary requirements relating to PIDIREGAS.

As of January 1, 2009, the provisions of NEIFGSP 009 were declared ineffective (see Note 2). Therefore, all PIDIREGAS-related accounting items have since such date been incorporated into the NEIFGSP consolidated financial statements. For Mexican FRS purposes, there has been no effect on the financial information.

(h) Wells, pipelines, properties, plant and equipment

Investments in properties, wells, pipelines, furniture and equipment are recorded at the cost of acquisition or construction, using—in the case of wells—the successful efforts method. Until December 31, 2007, these costs were adjusted for inflation using factors derived from the NCPI.

During the construction period, the CFR directly related to these assets is capitalized as part of the construction cost of these assets.

Depreciation is calculated from the month following the date when the asset was placed in service, using the straight-line method of accounting based on the expected useful lives of the assets, based on appraisals prepared by independent appraisers. The annual depreciation rates used by PEMEX are as follows:

	%	Years
Buildings	3	33
Plants and drilling equipment	3-5	20-33
Furniture and fixtures	10-25	4-10
Offshore platforms	4	25
Transportation equipment	4-20	5-25
Pipelines	4	25
Software/computers	10-25	4-10

The gains or losses generated by the sale or disposal of fixed assets are recognized in income for the period in which they are incurred.

The amortization of wells is determined based on the estimated commercial life of the field in which they are located, considering the ratio of the production of barrels of crude oil equivalent for the period to proved developed reserves of the field, as determined at the beginning of the year.

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS—(Continued)

FOR THE YEARS ENDED DECEMBER 31, 2009, 2008 AND 2007

(Figures stated in thousands of Mexican pesos, except as noted)

The carrying value of these assets is subject to an annual impairment assessment (see Note 9(d)).

(i) Impairment of the value of long-lived assets

Long-lived assets are subject to an annual study to determine their value of use and whether there is any impairment. Recoverability of assets to be held and used is measured by a comparison of the carrying value of an asset to future net revenues expected to be generated by the asset. If the carrying value of an asset exceeds its estimated net revenues, an impairment charge is recognized in the amount by which the asset’s carrying value exceeds its fair value. During 2009 and 2008, an impairment was recorded of Ps. 1,731,229 and Ps. 807,050, respectively. Additionally in 2008, a reversal of impairment in the amount of Ps. 699,847 was recorded. Therefore, for the year ended December 31, 2008, the net effect of the impairment of the value of long-lived assets represented an expense of Ps. 107,203, which was recognized directly in the statement of operations. For the year ended December 31, 2007, no impairment of assets was recognized.

(j) Exploration and drilling costs and specific oil-field exploration and depletion of fields reserve

PEMEX uses the successful efforts method of accounting for the recording of oil and gas exploration and drilling costs. Exploration costs are charged to income when incurred, while expenditures for exploratory drilling costs are included in fixed assets while pending determination of proven reserves. Exploration wells more than 12 months old are expensed unless: (a) (i) they are in an area requiring major capital expenditure before production can begin, (ii) commercially productive quantities of reserves have been found, and (iii) they are subject to further exploration or appraisal activity, in that either drilling of additional exploratory wells is underway or firmly planned for the near future; or (b) proved reserves are recorded within 12 months following the completion of exploratory drilling. The costs for the drilling of development wells are capitalized, whether or not successful.

PEMEX’s management makes semi-annual assessments of the amounts included within fixed assets to determine whether capitalization is initially appropriate and can continue. Exploration wells capitalized beyond 12 months are subject to additional scrutiny as to whether the facts and circumstances have changed and therefore whether the conditions described in clauses (a) and (b) of the preceding paragraph no longer apply.

(k) Reserve for abandonment cost of wells

The Reglamento de Trabajos Petroleros (Petroleum Works Law) provides that once a well turns out to be dry, is invaded with salt water or is abandoned due to mechanical failure, or when the well’s production has been depleted such that abandonment is necessary due to economic unfeasibility of production, it must be plugged to ensure the maintenance of sanitary and safe conditions and to prevent the seepage of hydrocarbons to the surface. All activities required for plugging a well are undertaken for the purpose of properly and definitively isolating the cross formations in the perforation that contains oil, gas or water, to ensure that hydrocarbons do not seep to the surface. This law also requires that PEMEX obtain approval from the Secretaría de Energía (Ministry of Energy) for the dismantlement of hydrocarbon installations, either for the purpose of replacing them with new installations or for permanent retirement.

The abandonment costs related to wells currently in production and wells temporary closed are recorded based on the Units of Production (“UOP”) method. In the case of non-producing wells subject to abandonment

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS—(Continued)

FOR THE YEARS ENDED DECEMBER 31, 2009, 2008 AND 2007

(Figures stated in thousands of Mexican pesos, except as noted)

and dismantlement the full cost is recognized at the end of each period. All estimates are based on the useful life of the wells, considering their present value (discounted). Salvage values are not considered, as these values commonly have not existed. These costs are initially capitalized as part of the well value, and amortized according to its useful life.

The reserve for abandonment costs of wells (plugging and dismantling), as of December 31, 2009 and 2008 was Ps. 24,488,953 and Ps. 18,775,600, respectively, and is included in long-term liabilities.

(l) Accruals

PEMEX recognizes, based on management estimates, accruals for those present obligations for which the transfer of assets or the rendering of services is probable and arises as a consequence of past events—primarily the payment of salaries and other employee payments, as well as environmental liabilities. In certain cases, such amounts are recorded at their present value.

(m) Employee benefits

Effective January 1, 2008, PEMEX adopted the provisions of FRS D-3 “Employee Benefits,” as issued by the Consejo Mexicano para la Investigación y Desarollo de Normas de Información Financiera, A.C. (Mexican Financial Reporting Standards Board, or “CINIF”), which has the principal objective of anticipating the recognition of the liabilities generated with respect to the benefits provided to employees.

The accumulated benefits related to pensions, seniority premiums, other post-retirement benefits and employment termination for causes other than restructuring, to which all employees are entitled, are recorded in the statement of operations of each year based on actuarial valuations performed by independent experts, using the projected unit-credit method (see Note 12).

The amortization periods of the unamortized items are as follows:

• Retirement benefits:

i. Initial transition liability and salary increases due to promotions, over a maximum of five years.

ii. Plan amendments and actuarial gains and losses for the period, over the employees’ average remaining labor life.

• Termination benefits:

i. Initial transition liability and plan amendments, over a maximum of five years.

ii. Salary increases due to promotions, over a maximum of one year.

iii. Actuarial gains and losses, immediate recognition.

As of December 31, 2009, the employees’ average remaining labor life for those employees entitled to benefits in the plan was approximately nine years. PEMEX has incorporated the effect of its labor obligations into these consolidated financial statements.

The plan for other post-retirement benefits includes medical services for retired personnel and their dependents, as well as benefits payable in cash for gas, gasoline and basic necessities.

(Figures stated in thousands of Mexican pesos, except as noted)

(n) Financial instruments and hedging operations

As of January 1, 2005, PEMEX adopted the provisions of Bulletin C-10 “Derivative Financial Instruments and Hedging Operations” (“Bulletin C-10”), as issued by the Mexican Institute of Public Accountants, A.C., which details the criteria for the recognition, valuation, registration, disclosure, presentation and, where appropriate, bifurcation from the host contract, that are applicable to derivative financial instruments (“DFIs”) for trading and hedging purposes, and to embedded derivatives.

As of December 31, 2009 and 2008, the DFIs recognized in the balance sheet were valued at their fair value, in accordance with the provisions of Bulletin C-10 (see Note 11). Changes in the fair value of DFIs held for trading purposes are recorded in the CFR. DFIs that are designated as hedges are recorded using cash flow or fair value hedge accounting, as is established in Bulletin C-10.

(o) Financial instruments with characteristics of liability, equity or both

Financial instruments issued by PEMEX with characteristics of liability, equity or both, are recorded at the time of issuance as a liability, equity or both, depending on their components, in accordance with FRS C-12 “Financial Instruments with characteristics of Liability, Equity or both.”

Initial costs incurred in the issuance of those instruments are assigned to liabilities and equity in the same proportion as the amounts of their components. Gains or losses related to the components of financial instruments classified as liabilities are recorded in the CFR. The distribution of profits to the owners of the components of financial instruments classified as equity is charged to equity.

(p) Restatement of equity, other contributions and retained earnings

Until December 31, 2007, the restatement of equity, other contributions and accumulated losses was determined by applying factors derived from the NCPI measuring accumulated inflation from the dates when the contributions were made; accumulated losses were generated to the 2007 year-end. As discussed above, as of December 31, 2007, the economic environment became non-inflationary, as defined by FRS B-10.

(q) Surplus in the restatement of equity

Until December 31, 2007, the surplus in the restatement of equity represented the cumulative results from the initial net monetary position and the results from holding non-monetary assets (mainly inventories and properties and equipment), restated in Mexican pesos with purchasing power as of the most recent balance sheet date. In 2008, the surplus in the restatement of equity was reclassified to accumulated results.

(r) Taxes and federal duties

Petróleos Mexicanos and the Subsidiary Entities are subject to special tax laws, which are based mainly on petroleum production, price forecasts and revenues from oil and refined products. Petróleos Mexicanos and the Subsidiary Entities are not subject to the Ley del Impuesto Sobre la Renta (Income Tax Law) or the Ley del Impuesto Empresarial a Tasa Única (Flat Rate Business Tax, or “IETU”) (see Note 18).

(s) Special Tax on Production and Services (“IEPS Tax”)

The IEPS Tax charged to customers is a tax on domestic sales of gasoline and diesel. The applicable rates depend on, among other factors, the product, producer’s price, freight costs, commissions and the region in which the respective product is sold.

(Figures stated in thousands of Mexican pesos, except as noted)

(t) Revenue recognition

For all export products, risk of loss and ownership (title) is transferred upon shipment. PEMEX therefore records sales revenue upon shipment to customers abroad. In the case of certain domestic sales in which the customer takes product delivery at a PEMEX facility, sales revenues are recorded at the time of delivery. For domestic sales in which PEMEX is responsible for product delivery, risk of loss and ownership is transferred at the delivery point, and PEMEX records sales revenue upon delivery.

(u) Comprehensive result

Comprehensive result represents the sum of net income (loss) for the period, and the accumulated translation effect, plus the effect of valuation of financial instruments designated as cash flow hedges. Until December 31, 2007, comprehensive result included the effects of inflation restatement, the equity effect of the employee benefits provision as well as items required by specific accounting standards to be reflected in equity but not constituting equity contributions, reductions or distributions, and was adjusted for inflation using factors derived from the NCPI.

(v) Comprehensive financing result (CFR)

CFR includes interest income and expense, foreign exchange gains and losses, the valuation effects of financial instruments and, until December 31, 2007, the gain or loss attributable to the effects of inflation on monetary assets and liabilities, minus any portion of the CFR capitalized (see Notes 9 and 11).

Transactions in foreign currencies are recorded at the exchange rate in effect on the date of execution or settlement. Foreign currency assets and liabilities are translated at the exchange rate in effect at the balance sheet date. Foreign exchange differences arising from assets and liabilities denominated in foreign currencies are recorded in income for the year.

Until December 31, 2007, the monetary position presented was determined by multiplying the difference between monetary assets and liabilities at the beginning of each month, including deferred taxes, by inflation rates through year-end. The aggregate of these results represented the monetary gain or loss for the year arising from inflation, which was reported in the statement of operations for the year.

(w) Contingencies

Liabilities for loss contingencies are recorded when it is probable that a liability has been incurred and the amount thereof can be reasonably estimated. When a reasonable estimation cannot be made, qualitative disclosure is provided in the notes to the consolidated financial statements. Contingent revenues, earnings or assets are not recognized until realization is assured (see Note 16).

(x) Deferred taxes

Deferred taxes are recorded based on the assets and liabilities method, which consists of the recognition of deferred taxes by applying the rate of the tax on hydrocarbon income to the temporary differences between the book and the tax values of assets and liabilities at the date of the consolidated financial statements. One Subsidiary Entity generated deferred hydrocarbon taxes, derived mainly from customer advances, accruals and fixed assets (see Note 18).

(y) Accounting changes

The CINIF issued the following FRS effective for fiscal years beginning January 1, 2008.

(i) FRS B-10 “Effects of Inflation”—FRS B-10 superseded the previous Bulletin B-10 “Recognition of the effects of inflation on the financial information” and its five amendments, as well as the related circulars and Interpretation of Financial Reporting Standards (“INIF”) No. 2. The principal guidelines established by this FRS include:

• Recognition of the effects of inflation. An entity operates in either a) an “inflationary” economic environment, when cumulative inflation over the immediately preceding 3-year period is equal to or greater than 26%; or b) a “non-inflationary” economic environment, when inflation over the aforementioned period is less than 26%.

In case a), as under the superseded previous Bulletin B-10, the comprehensive recognition of the effects of inflation is required. In case b), the effects of inflation are not recognized. However, as of the effective date of this FRS and when an entity ceases to operate in an inflationary economic environment, the restatement effects determined through the last period in which the entity operated in an inflationary economic environment (in PEMEX’s case, the 2007 year), must be retained and reclassified on the same date and using the same procedure as that of the corresponding assets, liabilities and stockholders’ equity. Should the entity in the future be once again operating in an inflationary economic environment, the cumulative effects of inflation not recognized in the periods when the environment was non-inflationary must be recognized retroactively.

• Price index. The change in the NCPI or in the value of the Unidad de Inversión (Investment Unit, or “UDI”) may be used for determining the inflation for a given period.

• Valuation of inventories and of foreign machinery and equipment. The use of replacement costs for inventories and of specific indexation for foreign machinery and equipment are no longer allowed.

• Equity adjustment for non-monetary assets. As of the effective date of this FRS, the unrealized portion of the equity adjustment for non-monetary assets maintained in equity should be identified, in order to be reclassified to earnings for the year when the originating item is realized. The realized portion, or when it is not feasible to identify the unrealized portion then both the realized and unrealized portions, should be reclassified to retained earnings.

• Monetary position gains or losses. Such gains or losses (included under deficit or surplus in the restatement of equity) were reclassified to retained earnings as of the effective date of this FRS.

As a consequence of the adoption of this FRS, as of January 1, 2008, equity items were reclassified as shown in the statement of changes in equity.

In these consolidated financial statements, amounts pertaining to the year ended December 31, 2007 are presented in constant pesos at December 31, 2007, the date on which the comprehensive method for recognizing the effects of inflation was last used.

(Figures stated in thousands of Mexican pesos, except as noted)

(ii) FRS D-3 “Employee benefits”—FRS D-3 superseded the previous Bulletin D-3 “Labor Obligations” and the portions of Bulletin D-4 “Accounting for income and asset taxes and employee statutory profit sharing” and INIF 4 that are applicable to Employee Statutory Profit Sharing (“ESPS”). The principal guidelines established by this FRS are:

• A change in the rates for the financial assumptions to be used in actuarial valuations from real rates to nominal rates.

• The incorporation of the term “salary increases due to promotions” with effect in liability and in cost.

• A maximum five-year period for amortizing unrecognized/unamortized items and, in the context of retirement benefits, for amortizing salary increases due to promotions.

• Unlike termination benefits, post-employment benefits and actuarial gains or losses may be immediately recognized in the results of operations or amortized over the employees’ average remaining labor life or a maximum of five years.

• Elimination of the recognition of an additional liability, the related intangible asset and the effect on equity from labor obligations.

As a result of the adoption of this FRS, PEMEX eliminated in 2008 an intangible asset of Ps. 72,008,835 and additional minimum pension liability of Ps. 123,768,374 previously reflected in the balance sheet, as well as an effect on equity from labor obligations of Ps. 51,759,539 previously presented in equity.

(iii) FRS D-4 “Taxes on income”—FRS D-4 superseded Bulletin D-4 and Circulars 53 and 54. The principal guidelines established by this FRS are:

• Reclassification, on January 1, 2008, of the balance of the cumulative income tax effects resulting from the initial adoption of Bulletin D-4 in 2000 to retained earnings, unless identified with any other comprehensive item pending reclassification.

• Transfer of the accounting treatment of ESPS (current and deferred) to FRS D-3, as outlined above.

As a result of the recognition of this FRS, the deferred income tax effect of Ps. 3,596 was reclassified to the comprehensive result within equity as of December 31, 2008.

(iv) FRS B-2 “Statement of cash flows”—FRS B-2 superseded Bulletin B-12 “Statement of changes in financial position” and paragraph 33 of Bulletin B-16. The principal guidelines established by this FRS are:

• Replacement in the financial statements of the statement of changes in financial position with the statement of cash flows for all periods, except those for periods prior to 2008, presented comparatively with those of the current period.

• Reporting of cash inflows and cash outflows in nominal currency units, i.e., not including the effects of inflation.

• Establishment of two alternative preparation methods (direct and indirect), without stating a preference for either method. In addition, cash flows from operating activities are to be reported first, followed by cash flows from investing activities and finally cash flows from financing activities.

(Figures stated in thousands of Mexican pesos, except as noted)

• Reporting of captions of principal items as gross, with certain exceptions, and required disclosure of the composition of items considered cash equivalents.

Accordingly, PEMEX has prepared a statement of changes in financial position for 2007 and statements of cash flows for 2008 and 2009 under the indirect method.

(v) FRS B-15 “Translation of foreign currencies”—FRS B-15 superseded the previous Bulletin B-15 “Foreign currency transactions and translation of financial statements of foreign operations.” The principal guidelines established by this FRS are:

• Substitution of the integrated foreign operation and foreign entity concepts for determining recording, functional and reporting currencies, requiring that translation be made based on the economic environment in which the entity operates, regardless of its dependency on a holding company.

• Inclusion of translation procedures for those cases where the recording and reporting currencies differ from the functional currency, providing the option not to conduct such translation to companies not subject to consolidation or valuation based on the equity method.

• The requirement that the accounting changes produced by the initial application of this standard be recognized prospectively; i.e., in a non-inflationary economic environment, without modifying the translation already recognized in the consolidated financial statements of prior periods.

The effect as of December 31, 2008 on the consolidated financial statements of the adoption of this FRS is a credit to equity of Ps. 2,809,574, as part of foreign operations translation effect, and a loss in the statement of operations of Ps. 2,847,846.

(z) Reclassifications

PEMEX’s consolidated financial statements as of December 31, 2008 and 2007 have been reclassified in certain accounts with the purpose of making them comparable with the consolidated financial statements as of December 31, 2009.

(1) As of December 31, 2007, the investment in Repsol YPF, S.A. (“Repsol”) consisted of 59,884,453 shares. On September 24, 2008, RepCon Lux announced the early redemption of its bonds exchangeable for Repsol shares, exercising its right of redemption in cash to certain holders. For such purpose, the equivalent shares were sold in the market through financial institutions. The settlement was realized and carried out in its entirety on October 24, 2008. However, the majority of the holders chose to exchange their bonds for shares prior to the date of the settlement. Considering that the holders had the right to exchange their bonds for Repsol shares prior to redemption, the intrinsic value of the bonds at the time of the redemption proved substantially equivalent to the value of the Repsol shares.

In order to retain the economic and voting rights in respect of 58,679,800 Repsol shares, or approximately 4.81% of Repsol’s share capital, PEMEX entered into four equity swaps with financial institutions, thereby obtaining the economic and voting rights in respect of 58,679,799 Repsol shares; PEMEX holds the remaining Repsol share through PMI-SES (see Note 11(v)).

(2) PMI NASA has a 50% joint venture with Shell Oil Company for the operation of a refinery located in Deer Park, Texas. The investment is accounted for under the equity method. During 2009, 2008 and 2007, PEMEX recorded Ps. (1,363,510), Ps. 1,748,582 and Ps. 4,944,329 of (loss) and profit, respectively, related to its equity in the results of the joint venture, which has been recorded under “profit sharing in non-consolidated subsidiaries, affiliates and others” in the statement of operations.

b. The combined depreciation of fixed assets and amortization of wells for the fiscal years ended December 31, 2009, 2008 and 2007, recognized in operating costs, was Ps. 76,890,687, Ps. 89,840,495 and Ps. 72,591,718, respectively, which includes amortization costs related to dismantlement and abandonment of wells for the years ended December 31, 2009, 2008 and 2007 of Ps. 1,648,884, Ps. 2,144,911 and Ps. 2,554,062, respectively.

c. As of December 31, 2009 and 2008, the capitalized portion related to dismantlement and abandonment costs, net of accumulated amortization, and determined based on the present value (discounted) of the project cost, was Ps. 24,488,953 and Ps. 18,775,600, respectively.

d. As of December 31, 2009 and 2008, an impairment of Ps. 1,731,229 and Ps. 807,050, respectively, was recorded. Additionally, in 2008, there was a reversal of impairment of Ps. 699,847 related to the Cosoleacaque petrochemical complex due to the recovery of the markets where that complex’s main product is sold. Therefore, for the year ended December 31, 2008, the net impairment of long-lived assets under FRS C-15 was Ps. 107,203, which was recorded in the statement of operations. As of December 31, 2009 and 2008, PEMEX recognized cumulative impairment charges in the value of long-lived assets amounting to Ps. 16,217,180 and Ps. 14,485,951, respectively.

NOTE 10—DEBT:

Under the Ley General de Deuda Pública (General Law of Public Debt), the SHCP authorizes Mexican Government entities, including Petróleos Mexicanos and the Subsidiary Entities, to negotiate and execute external financing agreements, defining the requirements that must be observed in each case.

Pursuant to the amendments to the Federal Law of Budget and Fiscal Accountability discussed in Note 2, Petróleos Mexicanos assumed during 2009, as primary obligor, all payment obligations under PIDIREGAS financings entered into by the Master Trust and Fideicomiso F/163, which had been guaranteed by Petróleos Mexicanos.

During 2009, the significant financing activities of Petróleos Mexicanos were as follows:

a. During the period from January 1 to December 31, 2009, Petróleos Mexicanos obtained U.S. $1,350,000 in nominal terms in loans made or guaranteed by export credit agencies for use in financing its investment program.

b. On January 21, 2009, Petróleos Mexicanos borrowed U.S. $984,000 under a revolving credit line, which it entered into on September 7, 2007.

NOTE 11—FINANCIAL INSTRUMENTS (DFIs):

PEMEX’s cash flows arising from its commercial and financial activities are exposed to the volatility of interest rates, currency exchange rates and hydrocarbons prices in the national and international markets.

In order to monitor and manage these risks, PEMEX has developed regulations relating to market risk management, which are comprised of policies and guidelines applicable to PEMEX that promote a comprehensive approach to managing such risk, regulate the use of DFIs, guide the development of hedging strategies and provide strategies for the formulation of risk limits estimates.

PEMEX’s risk management regulations provide that DFIs should generally be used only for the purpose of hedging. The use of DFIs for any other purpose must be approved in accordance with current internal regulations.

PEMEX has a policy of reducing the potential impact of market risk factors on its financial results by promoting a balance between expected incoming cash flows from operations and those outgoing, which relate to its liabilities.

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS—(Continued)

FOR THE YEARS ENDED DECEMBER 31, 2009, 2008 AND 2007

(Figures stated in thousands of Mexican pesos, except as noted)

(i) Counterparty and credit risk associated with DFIs

When the fair value of DFIs is favorable to PEMEX, it faces the risk that counterparties will not be able to meet their obligations. To reduce that risk, PEMEX monitors the creditworthiness of its counterparties and the credit risk exposure of the DFIs. PEMEX enters into transactions primarily with major financial institutions and hydrocarbon intermediaries with appropriate credit ratings, which ratings are issued and revised periodically by risk rating agencies. Additionally, PEMEX maintains a diversified portfolio of counterparties.

Pemex-Gas and Basic Petrochemicals faces additional credit risk due to its offering DFIs to its domestic customers to help them mitigate the volatility in the price of natural gas (see section (iv)). In order to qualify for these DFIs, Pemex-Gas and Basic Petrochemicals’ customers must be party to a current natural gas supply contract and sign a master hedging agreement, which is ancillary to such supply contract. These circumstances mean that the credit risk treatment of the DFIs is the same as that for the supply contracts.

Certain of Pemex-Gas and Basic Petrochemicals’ customers are exempt from presenting guarantees, while others make purchases on credit and are required to provide guarantees. In the event of nonpayment, supply is suspended and any open DFIs are liquidated. In 2009, the overdue accounts for natural gas of customers in the industrial and distribution sectors accounted for less than 1.00% of the total sales of Pemex-Gas and Basic Petrochemicals.

As of December 31, 2009, Pemex-Gas and Basic Petrochemicals had entered into DFIs with 186 of its customers, of which 174 (94%) were industrial customers and 12 (6%) were distributors. Of the total traded volume of DFIs, industrial customers represented 44% while distributors represented 56%.

As of December 31, 2009, MGI Supply, Ltd., a subsidiary of Pemex-Gas and Basic Petrochemicals, had provided U.S. $17,325,000 in collateral, as compared to no collateral having been provided for such DFIs at December 31, 2008.

(ii) Interest rate risk

PEMEX constantly monitors its exposure to the risk generated by volatility in the various reference interest rates applicable to its debt portfolio, as recognized in the balance sheet. To establish an appropriate proportion of fixed rate instruments in its portfolio, thus reducing its exposure to adverse movements in floating interest rates, PEMEX contracts for interest rate swaps associated with its variable-rate debt instruments. Under these swaps, PEMEX makes payments based on a fixed interest rate and receives payments based on a floating rate. LIBOR is the underlying floating rate for U.S. dollar-denominated swaps of PEMEX’s debt.

(iii) Foreign exchange rate risk

Most of PEMEX’s debt is denominated in U.S. dollars and Mexican pesos. Debt denominated in other currencies generates foreign exchange rate exposure that can increase PEMEX’s financing costs. Therefore, PEMEX regularly enters into cross-currency swaps to mitigate the exposure caused by the volatility in the exchange rates of currencies other than the U.S. dollar and the Mexican peso. The parity currencies underlying these swaps are the euro, Japanese yen, pound sterling and Swiss franc, which are swapped against the U.S. dollar.

FOR THE YEARS ENDED DECEMBER 31, 2009, 2008 AND 2007

(Figures stated in thousands of Mexican pesos, except as noted)

(iv) Hydrocarbon price risk

PEMEX’s tax structure permits it to transfer most hydrocarbon price risk to the Mexican Government. Therefore, PEMEX does not enter into long-term strategic hedging arrangements relating to the prices of the hydrocarbons that it trades.

However, PEMEX does periodically evaluate its exposure to international hydrocarbon prices and uses DFIs as a mechanism to mitigate identified potential sources of risk.

In addition to supplying natural gas, Pemex-Gas and Basic Petrochemicals enters as a counterparty into DFIs for natural gas with its domestic customers, in order to help those customers mitigate the risk of volatility in the prices of natural gas. In providing this service, Pemex-Gas and Basic Petrochemicals enters into corresponding DFIs through its subsidiary MGI Supply, Ltd., taking the positions opposite to those in its DFIs with customers—thereby mitigating the market risk generated by those DFIs offered to customers. In turn, MGI Supply, Ltd. enters into opposite position DFIs with international counterparties in order to transfer the related price risk. This system allows Pemex-Gas and Basic Petrochemicals to maintain overall its natural risk profile.

Since 2003, Pemex-Gas and Basic Petrochemicals has been required to trade Liquefied Petroleum Gas (“LPG”) under a price system imposed by the Mexican Government. This system fixes the sale price of LPG throughout Mexico, generating risk exposure in the geographic areas where Pemex-Gas and Basic Petrochemicals sells imported LPG. During 2009, Pemex-Gas and Basic Petrochemicals mitigated the market risk generated by that exposure by employing a hedging strategy consisting of propane swaps. Propane is the primary component of LPG.

(v) Risk relating to the portfolio of third-party shares

PEMEX retains a synthetic long position (holding) on 58,679,799 shares of Repsol YPF, with the objective of maintaining corporate rights over those shares. This is accomplished by using four total return swaps under which PEMEX has the right to receive the total return on the Repsol YPF shares with respect to an exercise price in U.S. dollars, as well as the dividends and corporate rights relating to those shares. Under these DFIs, PEMEX agrees to cover its financial counterparties for any capital losses that the Repsol YPF shares may experience in reference to an exercise price, as well as to make payments at a fixed interest rate. Additionally, two of these DFIs include structures composed of combinations of options, consisting in each case of one short call and one long put spread. The aforementioned DFIs have maturities between October 2010 and the first six months of 2011. As of December 31, 2009 and 2008, the share price for the related Repsol YPF shares was U.S. $26.66 and U.S. $21.10, respectively.

(vi) Fair value of DFIs

PEMEX monitors the fair value of its DFIs portfolio on a periodic basis. Fair value represents the price at which one party would assume the rights and obligations of the other, and is calculated for DFIs through models used commonly in the international financial markets, based on inputs obtained from major market information systems and price providers.

PEMEX’s DFIs portfolio is composed primarily of swaps whose prices can be estimated by discounting flows using appropriate factors, and contains no exotic instruments that require numerical methods for their valuation.

FOR THE YEARS ENDED DECEMBER 31, 2009, 2008 AND 2007

(Figures stated in thousands of Mexican pesos, except as noted)

The options contained in PEMEX’s DFIs portfolio are European in style, consisting of plain or digital calls or puts, and are valued internally based on the traditional Black-Scholes model or certain specialized variations thereof.

The inputs used in valuing PEMEX’s DFIs portfolio come from widely recognized price providers and do not require special adjustments or conversions.

(vii) Embedded derivatives due to a non-functional currency component

As of December 31, 2009 and 2008, in accordance with Bulletin C-10, PEMEX recognized several agreements relating to, among other things, services in connection with works projects, acquisitions, leases and insurance commitments. These agreements were entered into by PEMEX in foreign currencies, and in accordance with their terms, the related foreign currency components do not meet the criteria to generate an embedded derivative.

PEMEX enters into derivatives transactions with the sole purpose of hedging financial risks related to its operations, assets or liabilities recorded within its balance sheet. Nonetheless, some of these transactions do not qualify for hedge accounting treatment, because they do not meet the strict requirements of Bulletin C-10 for being designated as hedges. They are therefore recorded in the financial statements as non-hedge instruments or as instruments entered into for trading purposes, despite the fact that their cash flows are offset by the cash flows of the positions to which they relate. As a result, the changes in their fair value affect the CFR.

As of December 31, 2009 and 2008, the fair value of PEMEX’s DFIs was Ps. 9,239,778 and Ps. (2,429,936), respectively. These amounts include the DFIs designated as cash flow hedges and their net fair value of Ps. (64,711) and Ps. (2,374,351), respectively, which was recognized under other comprehensive loss.

The following table shows the fair values and the notional amounts of PEMEX’s over-the-counter derivative instruments that are designated as cash flow hedges outstanding as of December 31, 2009 and 2008:

DFIs designated as cash flow hedges that have the same critical characteristics as the item being hedged are considered highly effective.

In light of the foregoing, these instruments do not have an impact on earnings that is due to hedge inefficiency, and the change in their fair value is recognized in its entirety as part of equity through other comprehensive income. The fair value of these instruments is reclassified into earnings at the same time as the hedged item cash flows affect earnings.

As of December 31, 2009, 2008 and 2007, net (loss) income of Ps. (62,375), Ps. 1,062,359 and Ps. (1,479,284), respectively, was reclassified from other comprehensive income into earnings in the CFR. It is estimated that, in 2010, net income of Ps. 185,622 will be reclassified from other comprehensive income into earnings.

NOTE 12—EMPLOYEE BENEFITS:

a. Pensions, seniority premiums and other post-retirement benefits

PEMEX has established employee non-contributory retirement plans, under which benefits are determined based on employees’ years of service and final salary at their retirement date. Liabilities and costs of such plans, including those related to the seniority premium benefit, to which every employee is entitled upon termination of employment, are recorded in accordance with actuarial valuations performed by independent actuaries. PEMEX partially funds its employee benefits through a Mexican trust structure, the resources of which come from the seniority premium item of the Governmental Budget, or any other item that substitutes or could be connected to this item, or that is associated to the same item and the interests, dividends and capital gains obtained from the investments of the trusts.

PEMEX has also established plans for other post-retirement benefit obligations whose actuarial amounts are determined by independent actuaries. Such plans include medical services and cash provided to retired personnel and their dependents for basic necessities.

b. Benefits for employment termination for causes other than restructuring

Petróleos Mexicanos has established defined benefit plans to cover the payments that must be made when terminating employment, for causes other than restructuring, before the employee’s retirement age. These benefits are calculated based on years of service and the employee’s compensation at the time employment ends. The obligations and costs corresponding to these plans are recorded in accordance with actuarial valuations performed by independent actuaries.

Cash flows:

Plan contributions and benefits paid were as follows:

	Retirement Benefits
	2009		2008
Contribution to the pension plan assets	Ps.	20,331,433	Ps.	17,948,524
Payments charged to the plan assets		22,620,838		20,662,053

Payments charged to the reserve for medical and hospital services for retired personnel and pension recipients in 2009 and 2008 were Ps. 4,260,829 and Ps. 4,039,137, respectively. Payments for employment termination before the employee’s retirement age were Ps. 26,525 in 2009. Such payments were not required in 2008.

The cost, obligations and other elements of the pension plan, seniority premium and other post-retirement benefits plans for termination for causes other than restructuring, mentioned in Note 3(m), were determined based on calculations prepared by independent actuaries as of December 31, 2009 and 2008.

NOTE 14—EQUITY:

On December 31, 1990, certain debt owed by Petróleos Mexicanos to the Mexican Government was capitalized as equity. This capitalization amounted to Ps. 22,334,195 in nominal terms (U.S. $7,577,000) and was authorized by the Board.

In December 1997, the Board and the Mexican Government agreed to a reduction in equity of the Certificates of Contribution “A” in exchange for a payment in cash to the Mexican Government of Ps. 12,118,050 (U.S. $1,500,000). As of December 31, 2009, the value of the Certificates of Contribution “A” was Ps. 10,222,463 (historical value of Ps. 10,216,145 plus an adjustment of Ps. 6,318).

The capitalization agreement between Petróleos Mexicanos and the Mexican Government states that the Certificates of Contribution “A” constitute permanent capital. As a result, the Certificates of Contribution “A” are as follows:

	Amount
Certificates of Contribution “A”	Ps.	10,222,463

During January 2007, Petróleos Mexicanos paid Ps. 4,270,224 to the Mexican Government in advance for a minimum guaranteed dividend to be paid as a condition of this capitalization. Through the CA-122/2008 agreement of August 20, 2008, the Board approved the application of this minimum guaranteed dividend, which was recognized in September 2008, as accumulated loss.

During 2007, the Mexican Government assigned to Petróleos Mexicanos excess revenues in accordance with the Federal Law of Budget and Fiscal Accountability, article 19, fraction IV, clauses b) and c) in the amount of Ps. 13,938,000. As of December 31, 2007, Petróleos Mexicanos had received Ps. 11,131,800 that it capitalized in equity. The other Ps. 2,806,200 was recognized as uncalled capital until it was received by Petróleos Mexicanos in February 2008. Additionally, Petróleos Mexicanos received Ps. 19,700 from the Fondo sobre Ingresos Excedentes (“FIEX”).

During 2008, the Mexican Government assigned to Petróleos Mexicanos excess revenues in accordance with the Federal Law of Budget and Fiscal Accountability, article 19, fraction IV, clauses b) and c) in the amount of Ps. 32,639,044. In addition, interest in the amount of Ps. 12,218 related to these payments by the Mexican Government was capitalized.

During 2009, due to certain changes in the fiscal regime of Petróleos Mexicanos, the SHCP requested the return of Ps. 40,104 as reimbursement of funds that had been received by Petróleos Mexicanos in 2008 under article 19, fraction IV, clause c) of the Federal Law of Budget and Fiscal Accountability. Additionally, PEMEX received under the terms of the same provision a payment in the amount of Ps. 12,600 corresponding to excess income from the 2008 fiscal year. The SHCP authorized application of this payment toward implementation of programs and investments in infrastructure projects. In addition, PEMEX capitalized an amount of Ps. 494,714, corresponding to interest earned at the end of 2009 on funds provided by the Mexican Government for use in infrastructure works, resulting in an overall increase in equity of Ps. 467,210 for the year.

In 2004, Petróleos Mexicanos signed an agency agreement establishing the Funds for Specific Purposes—Trade Commission (the “Trade Commission Funds”) with Banco Santander, S.A. as an agent in order to manage the funds transferred by the Mexican Government to Petróleos Mexicanos and the Subsidiary Entities. In accordance with the Ley de Ingresos de la Federación (Federal Revenues Law), these funds are to be utilized only for infrastructure works related to exploration, refining, gas and petrochemicals. Payments made by the Mexican Government that increase the equity of Petróleos Mexicanos and the Subsidiary Entities are deposited into the Trade Commission Funds.

As of December 31, 2009 and 2008, the outstanding balances of the Trade Commission Funds were as follows:

	2009		2008
Trade Commission “FEIIP”	Ps.	30,590,241	Ps.	29,023,651
Trade Commission “FEX”		982,967		15,179,213

Total funds for specific purposes	Ps.	31,580,688	Ps.	44,656,862

During recent years, PEMEX has recorded negative earnings. However, under the Ley de Concursos Mercantiles (“Commercial Bankruptcy Law of Mexico”), decentralized public entities such as Petróleos Mexicanos and the Subsidiary Entities cannot be subject to a bankruptcy proceeding.

agreements to which PEMEX currently is a party do not provide for financial covenants that would be breached or events of default that would be triggered as a consequence of negative equity. The Mexican Government has focused its recent efforts on consolidating PEMEX’s institutional strategy, including through the adoption of November 2008 amendments to PEMEX’s legal framework, which will permit it greater autonomy in decision making and enhanced operational viability.

NOTE 15—COMMITMENTS:

(a) PEMEX, through Pemex-Exploration and Production, is party to an evergreen contract to sell to PMI CIM crude oil destined for sale in the international market. Pursuant to this contract, PEMEX is required to sell to PMI CIM the volumes of crude oil that the latter needs to meet its commitments to its clients. The relative sale prices are fixed in accordance with those prevailing in the international market at the time of sale. PMI CIM’s hydrocarbons sales commitments to its clients are backed by PEMEX.

PMI has entered into several contracts for the sale of crude oil on the international market to foreign companies. The terms and conditions of these contracts are specific to each client, and their durations may be indefinite (evergreen contracts), and in some cases with a minimum obligatory period (long-term contracts).

(b) PEMEX has entered into a nitrogen supply contract for the pressure maintenance program at the Cantarell complex. During 2007, an additional contract was entered into with the purpose of supplying nitrogen to the Ku-Maloob-Zap complex and extending the original contract until 2027. As of December 31, 2009 and 2008, the value of the nitrogen to be supplied during the term of the contract was approximately Ps. 17,309,316 and Ps. 19,972,377, respectively. In the event of the annulment of the contract and depending on the circumstances, PEMEX has the right and obligation to acquire the vendor’s nitrogen plant under the terms of the contract.

Estimated future payments under this contract for upcoming fiscal years are as follows:

2010	Ps.	2,007,406
2011		2,022,583
2012		2,055,395
2013		1,392,635
2014		1,409,580
More than 5 years		8,421,717
Total	Ps.	17,309,316

(c) During 2008, PEMEX entered into a nitrogen supply contract for pressure maintenance at the Jujo Tecominoacán complex in the Southern Region. The term of this contract runs until 2017.

As of December 31, 2009 and 2008, the value of the nitrogen to be supplied during the term of the contract was approximately Ps. 2,443,574 and Ps. 2,661,262, respectively.

In the event of early termination of contract, under its terms, PEMEX would be required to pay for services received and for unrecoverable expenses of the counterparty.

NOTE 16—CONTINGENCIES:

In the ordinary course of business, PEMEX is named in a number of lawsuits of various types. PEMEX evaluates the merit of each claim and assesses the likely outcome, accruing a contingent liability when an unfavorable decision is probable and the amount is reasonably estimable. Other than as described in this note, there are no pending lawsuits to which PEMEX is a party in which it anticipates a significant contrary decision, and for which it has accrued related reserves.

(a) PEMEX is subject to the provisions of the Ley General del Equilibrio Ecológico y la Protección al Ambiente (General Law on Ecological Equilibrium and Environmental Protection). To comply with this law, environmental audits of PEMEX’s larger operating, storage and transportation facilities have been or are being conducted. Following the completion of such audits, PEMEX has signed various agreements with the Procuraduría Federal de Protección al Ambiente (Federal Attorney of Environmental Protection, or “PROFEPA”) to implement environmental remediation and improve environmental plans. Such plans contemplate remediation for environmental damages, as well as related investments for the improvement of equipment, maintenance, labor and materials.

As of December 31, 2009 and 2008, the reserve for environmental remediation expenses totaled Ps. 6,032,931 and Ps. 1,751,453, respectively. This reserve is included in the reserve for sundry creditors and others as a long-term liability in the balance sheet.

(b) PEMEX is involved in various civil, tax, criminal, administrative, labor, commercial lawsuits and arbitration proceedings. The result of these proceedings is uncertain as of this date. Based on the information available, the amount claimed in connection with these lawsuits as of December 31, 2009 totaled approximately Ps. 44,291,614. As of December 31, 2009, PEMEX had accrued a reserve of Ps. 9,918,378 for these contingent liabilities. The current status of the principal lawsuits in which PEMEX is involved is as follows:

In September 2001, Conproca, S.A. de C.V. (“CONPROCA”), the construction company performing construction and maintenance services for Pemex-Refining’s Cadereyta refinery, filed a claim for arbitration before the International Court of Arbitration of the International Chamber of Commerce (the “ICA”) against Pemex-Refining and Petróleos Mexicanos (No. 11760/KGA) related to expenses incurred by CONPROCA for, among other things, additional work performed and value added. On December 17, 2008, the ICA issued a general liability award in favor of CONPROCA (of which Pemex-Refining was notified on December 22, 2008), without specifying an amount to be paid by Pemex-Refining or Petróleos Mexicanos. On November 30, 2009, the parties submitted briefs and evidence in support of the respective amounts of

their claimed liability. CONPROCA is seeking a total amount of U.S. $424,890.3 and Petróleos Mexicanos and Pemex-Refining are seeking U.S. $116,025.1. As of the date of this report, Petróleos Mexicanos and Pemex-Refining are preparing a brief in connection with a hearing to determine the amounts due to each party.

As of the date of this report, only one of the several claims filed by a group of Congressmen from the LIXth Legislature related to the FPWC program remains pending. Pemex-Exploration and Production has obtained favorable judgments in the other similar claims filed by these plaintiffs. This remaining claim (No. 226/2004-IV) is related to the FPWC entered into between Pemex-Exploration and Production and PTD Servicios Múltiples, S. de R.L. de C.V. for the Cuervito natural gas production block, and was filed before the Juzgado Noveno de Distrito en Materia Civil del Distrito Federal (Ninth Civil District Court of the Federal District). The claim does not seek monetary relief, but instead to prevent the performance of this FPWC through a declaration that it is void based on the alleged violation of Article 27 of the Mexican Constitution. On June 7, 2008, Pemex-Exploration and Production responded to this claim. On April 19, 2010, the court issued a resolution declaring that the period for legal action had lapsed. The plaintiffs filed an appeal of this resolution before the Primer Tribunal Unitario en Materia Civil del Primer Circuito (First Unit Civil Court of the First Circuit), which confirmed the resolution but released the plaintiffs from a requirement that they pay court expenses.

In December 2004, Corporación Mexicana de Mantenimiento Integral, S. de R.L. de C.V. (“COMMISA”) filed an arbitration claim before the ICA against Pemex-Exploration and Production (arbitration related to project No. IPC-01) for, among other things, a breach of a construction agreement in connection with two platforms in the Cantarell complex. The detailed claim filed by COMMISA seeks damages of U.S. $319,920.3 and Ps. 37,209.4. Pemex-Exploration and Production responded to the claim and filed a counterclaim against COMMISA, seeking U.S. $125,897.7 and Ps. 41,513. On January 13, 2010, the ICA notified Pemex-Exploration and Production that it had rendered a decision, dated December 16, 2009, requiring Pemex-Exploration and Production to pay COMMISA sums of approximately U.S. $293,645.9 and Ps. 34,459.5, plus interest, but also requiring COMMISA to pay Pemex-Exploration and Production a sum of approximately U.S. $5,737, plus interest. On January 11, 2010, Pemex-Exploration and Production had been notified that COMMISA had filed a motion before the U.S. District Court for the Southern District of New York requesting the enforcement of the ICA award in its favor. As of the date of this report, Pemex-Exploration and Production is seeking to have this action dismissed. On July 1, 2010, a hearing will be held. In addition, Pemex-Exploration and Production has filed a motion before the Juzgado Quinto de Distrito en Materia Civil (Fifth Civil District Court), requesting that the award be declared null and void. The resolution of this claim is still pending.

In January 2006, Tejas Gas de Toluca, S. de R.L. de C.V. (“TGT”) commenced an arbitration proceeding against Gas Natural México, S.A. de C.V. (“GNM”) and Pemex-Gas and Basic Petrochemicals, seeking, among other things, to enforce compliance with a transportation agreement and its amendments dated February 2001 and November 2001. This agreement was entered into for the operation of the Palmillas-Toluca pipeline. On May 27, 2010, the parties executed a settlement agreement in connection with this claim. Additionally, they agreed to execute a new transportation agreement. On May 28, 2010, the parties notified the ICA of the settlement agreement, to facilitate its issuance of a final award on such terms.

On December 16, 2005, Asociación de Transportistas al Servicio de Petróleos Mexicanos, Clientes o Empresas Sustitutos, A.C. (“Asociación de Transportistas”) filed a claim (No. 271/2005-I) before the Juzgado Quinto de Distrito en Materia Civil (Fifth Civil District Court) in the Federal District, seeking a declaration that Pemex-Refining was in breach of a transportation agreement dated March 26, 1993, as well

as the payment of related damages. Asociación de Transportistas is also seeking that Pemex-Refining authorize the plaintiff to replace tank trucks older than ten years, register these new tank trucks and assign them a cargo. On April 29, 2008, a judgment was issued against Pemex-Refining. Pemex-Refining filed an appeal (No. 425/2008) against this resolution before the Primer Tribunal Unitario en Materia Civil y Administrativa del Primer Circuito (First Unit Civil and Administrative Court of the First Circuit), which was granted on October 26, 2009. The plaintiff filed a form of constitutional relief known as an amparo (No. 696/2009) against this resolution before the Décimo Segundo Tribunal Colegiado (Twelfth Joint Court), which affirmed the previous resolution in favor of Pemex-Refining. This proceeding has therefore concluded. In three other claims filed separately by Asociación de Transportistas against Pemex-Refining, judgments have been granted in favor of Pemex-Refining.

On August 20, 2007, Petróleos Mexicanos and Pemex-Refining were summoned before the Juzgado Decimocuarto de Distrito del Décimo Circuito (Fourteenth District Court of the Tenth Circuit) in Coatzacoalcos, Veracruz in connection with a civil claim (No. 12/2007) filed by Leoba Rueda Nava, seeking approximately Ps. 2,896,927.4 for, among other things, civil liability and damages resulting from the pollution of land used to store oil waste. On May 19, 2010, a final judgment was issued in favor of the plaintiff. Petróleos Mexicanos and Pemex-Refining were ordered to pay Ps. 995,136.8, plus interest, as well as expenses related to the claim. On May 26, 2010, the defendants filed an appeal against this judgment before a Tribunal Unitario del Décimo Circuito (Unit Court of the Tenth Circuit) in Villahermosa, Tabasco. As of the date of this report, a final resolution is still pending.

In December 2003, Unión de Sistemas Industriales, S.A. de C.V. filed a claim (No. 202/2003) before the Juzgado Tercero de Distrito en Materia Civil (Third Civil District Court) in the Federal District against Pemex-Refining, seeking approximately Ps. 393,000 for, among other things, work performed and not paid for under a pipeline construction agreement, as well as expenses related to the claim. A final judgment was issued against Pemex-Refining in which it was ordered to pay Ps. 89,000. Both parties filed appeals (No. 204/2009 and No. 205/2009) against this resolution before the Segundo Tribunal Unitario en Materia Civil y Administrativa del Primer Circuito (Second Unit Civil and Administrative Court of the First Circuit). On November 23, 2009, a resolution was granted in favor of Pemex-Refining. The plaintiff filed an amparo (D.C. 03/2010) before the Décimo Tribunal Colegiado en Materia Civil (Tenth Joint Civil Court) against this resolution. Pemex-Refining also filed an amparo (D.C. 04/2010) before the Tenth Joint Civil Court since it was ordered to grant a discharge in favor of the plaintiff. On May 26, 2010, a resolution was issued against Pemex-Refining’s amparo and in favor of the plaintiff’s. The court ordered that the pleadings filed by the plaintiff be analyzed. As of the date of this report, a final resolution is still pending.

On August 16, 2006, two separate amparos (No. 723/2006 and No. 724/2006) were filed by Minera Carbonífera Río Escondido, S.A. de C.V. and Minerales Monclova, S.A. de C.V. before the Juzgado Cuarto de Distrito en Materia Administrativa (Fourth Administrative District Court) in the Federal District, alleging that the Regulatory Law was unconstitutional and that Pemex-Exploration and Production had violated each entity’s constitutional rights by carrying out development, infrastructure and maintenance projects in non-associated gas fields under a public works contract. A constitutional hearing will be held on July 6, 2010. An expert’s opinion on geology to be filed by Pemex-Exploration and Production is still pending.

On April 14, 2010, Petróleos Mexicanos and Pemex-Gas and Basic Petrochemicals were summoned before the Juzgado Séptimo de Distrito (Seventh District Court) in Reynosa, Tamaulipas, in connection with a claim filed by Irma Ayala Tijerina de Barroso and others, seeking approximately Ps. 1,490,873 for, among other things, civil liability and damages resulting from the pollution of land used for water treatment in the Reynosa Gas Processing Complex. On May 7, 2010, Petróleos Mexicanos and Pemex-Gas and Basic

Petrochemicals responded to this claim, objecting that the court lacked jurisdiction to hear it. This objection was admitted and the principal claim has therefore been suspended. A final resolution is still pending.

In January 1993, Pemex-Refining entered into a joint venture with Impulsora Jalisciense, S.A. de C.V. (“Impulsora”) to establish a new company called Mexicana de Lubricantes, S.A. de C.V. (“Mexicana de Lubricantes”), which manufactures, bottles and distributes automotive and industrial lubricants and greases. Currently, Pemex-Refining is involved in certain litigation and administrative proceedings in connection with this joint venture, including the following:

• On December 5, 2005, Impulsora filed an amparo (No. 1519/2005) before the Juzgado Quinto de Distrito en Materia Administrativa (Fifth Administrative District Court) in the state of Jalisco, in connection with a constitutional challenge to the Ley Federal de Procedimiento Administrativo (Federal Law of Administrative Procedure) and a resolution (Acuerdo No. PMREF-00-002) modifying the franchise agreement among Pemex-Refining and the service stations franchised by Pemex-Refining. This proceeding has been joined with a pending claim filed by Bardahl de México, S.A. de C.V. (“Bardahl”), a competitor in the lubricants market, in which Bardahl asserts that it is the owner of the “Mexlub” trademark. As described further below, Bardahl seeks a ruling under which it would be permitted to sell its products in the service stations franchised by Pemex-Refining, thereby eliminating Mexicana de Lubricantes’ exclusive right to sell its lubricants in these service stations. A constitutional hearing will be held on July 9, 2010.

• On December 20, 2005, Pemex-Refining filed a commercial claim (No. 127/2005) against Mexicana de Lubricantes before the Juzgado Segundo de Distrito en Materia Civil (Second Civil District Court) in the state of Jalisco, to compel Impulsora to convene a general shareholders’ meeting to discuss Mexicana de Lubricantes’ financial information, as well as the appointment of its new board members and comptroller. On June 29, 2007, a judgment was issued in favor of Pemex-Refining, and Mexicana de Lubricantes was ordered to convene a general shareholders’ meeting. As of the date of this report, compliance with this final resolution is still pending.

• On June 7, 2006, Pemex-Refining filed a criminal complaint before the Procuraduría General de la República (Federal Attorney General’s Office) for fraud allegedly committed by members of the board of directors of Mexicana de Lubricantes. On July 17, 2009, Pemex-Refining filed an accounting report stating that it had suffered up to Ps. 25,828 in damages as a result of this alleged fraud. As of the date of this report, an expert’s opinion to be provided by the Federal Attorney General’s Office is still pending, and the matter remains under investigation.

• On October 17, 2006, Pemex-Refining filed a commercial claim (No. 222/2006) against Impulsora before the Juzgado Octavo de Distrito en Materia Civil (Eight Civil District Court) in Mexico City, seeking to enforce its contractual right to exercise an option to purchase those shares of Mexicana de Lubricantes owned by Impulsora. On November 30, 2009, a judgment was issued in favor of Impulsora on the basis of Mexicana de Lubricantes’ financial statements not yet having been approved—which would be necessary in determining whether it had realized any profit. Pemex-Refining filed an appeal against this resolution, which was denied on April 29, 2010. Pemex-Refining was ordered to pay court expenses and filed an amparo (No. 345/2010) against this resolution before the Sexto Tribunal Colegiado en Materia Civil del Primer Circuito (Sixth Joint Civil Court of the First Circuit). A final resolution is still pending.

• On February 2, 2007, Mexicana de Lubricantes filed a commercial claim (No. 28/2007) against Pemex-Refining before the Juzgado Primero de Distrito en Materia Civil (First Civil District

Court) in the Federal District seeking, among other things, a judgment declaring null and void any advance termination or cancellation of the following agreements executed between Mexicana de Lubricantes and Pemex-Refining: (i) a license and trademark contract; (ii) a basic greases supply contract; and (iii) a contract for the manufacture of lubricants and greases for Petróleos Mexicanos and the subsidiary entities. On March 16, 2010, a judgment was issued in favor of Pemex-Refining. Mexicana de Lubricantes and Pemex-Refining each filed an appeal against this resolution before the First Unit Civil and Administrative Court of the First Circuit. A final resolution is still pending.

• On May 2, 2007, Bardahl filed a commercial claim (No. 95/2007) against Mexicana de Lubricantes and Pemex-Refining before the Juzgado Quinto de Distrito en Materia Civil del Tercer Circuito (Fifth Civil District Court of the Third Circuit) in Guadalajara, Jalisco, seeking that a trademark license agreement between Pemex-Refining and Mexicana de Lubricantes and its amendments be declared invalid because of an exclusivity clause that prevents the sale of Bardahl’s products in the service stations franchised by Pemex-Refining, as well as related damages. The plaintiff’s expert claims that Bardahl’s damages total up to Ps. 18,008,000, while the defendants’ expert claims that there are no damages. The trial is in the evidentiary stage, with the opinion of an independent expert still pending.

On November 3, 1997, the Comisión Federal de Competencia (Federal Competition Commission) initiated an investigation into Pemex-Refining’s business practices in connection with an exclusivity clause included in its license and trademark contracts executed with service stations franchised by Pemex-Refining, which provided that those service stations could only sell lubricants and greases bearing PEMEX or Mexicana de Lubricantes trademarks. On July 10, 2003, the Federal Competition Commission issued a resolution prohibiting Pemex-Refining from engaging in anti-competitive practices in relation to that exclusivity clause, requiring amendment of the related contracts within a period of six months to remove the clause and imposing a fine of 1,500 daily minimum wage units per day until such contracts were brought into compliance. However, this six-month deadline was suspended due to a motion filed by Impulsora. On January 23, 2008, the Federal Competition Commission notified Pemex-Refining that it would require compliance with the resolution described above within a period of no more than 15 business days, except for the requirement to amend the relevant contracts. On February 12, 2008, Pemex-Refining filed a response stating that it would be unable to comply with the resolution due to a definitive suspension granted to Bardhal in a related amparo (No. 373/2006, which is currently joined with amparo No. 1519/2005). On April 10, 2008, the Federal Competition Commission rejected this response and Pemex-Refining filed a subsequent motion to suspend the Federal Competition Commission’s resolution. That motion was granted on May 6, 2008. An amparo had been granted on April 30, 2008 in favor of Pemex-Refining, declaring unconstitutional the resolution originally issued by the Federal Competition Commission. The Federal Competition Commission filed a revised motion (No. R.A. 246/2008) before the Décimo Tribunal Colegiado del Primer Circuito (Tenth Joint Court of the First Circuit) objecting to the amparo, but that motion was denied. On September 28, 2009, the Federal Competition Commission reviewed the evidence filed by Pemex-Refining and ratified its initial resolution. On October 20, 2009, Pemex-Refining filed a new amparo (No. 1691/2009) before the Juzgado Décimo Tercero de Distrito en Materia Administrativa (Thirteenth Administrative District Court) in the Federal District, and a provisional suspension was granted. A constitutional hearing was to be held on June 17, 2010.

NOTE 17—SEGMENT FINANCIAL INFORMATION:

PEMEX’s primary business is the exploration and production of crude oil and natural gas and the refining and marketing of petroleum products, conducted through four business segments: Pemex-Exploration and Production, Pemex-Refining, Pemex-Gas and Basic Petrochemicals and Pemex-Petrochemicals. Management makes decisions related to the operations of the consolidated business along these four strategic lines.

The primary sources of revenue for the segments are as described below:

• Pemex-Exploration and Production earns revenues from domestic crude oil sales, as well as from the exporting of crude oil, through the PMI Group, to international markets. Export sales are made through the PMI Group to approximately 25 major customers in various foreign markets. Less than half of PEMEX’s crude oil is sold domestically; however, these amounts are in large part sufficient to satisfy Mexican domestic demand.

• Pemex-Refining earns revenues from sales of refined petroleum products and derivatives. Most of Pemex-Refining’s sales are to third parties and occur within the domestic market. The entity supplies the Comisión Federal de Electricidad (“CFE”) with a significant portion of its fuel oil production. Pemex-Refining’s most important products are different types of gasoline.

• Pemex-Gas and Basic Petrochemicals earns revenues primarily from domestic sources. Pemex-Gas and Basic Petrochemicals also consumes high levels of its own natural gas production. Most revenues of this entity are obtained from the sale of ethane and butane gas.

• Pemex-Petrochemicals is engaged in the sale of petrochemical products to the domestic market. Pemex-Petrochemicals offers a wide range of products. The majority of Pemex-Petrochemicals’ revenues comes from methane derivatives, ethane derivatives and aromatics and derivatives.

In making performance analyses for the entities, PEMEX’s management focuses on sales volumes and gross revenues as primary performance indicators.

Income (loss) and identifiable assets for each segment have been determined before intersegment adjustments. Sales between segments are made at internal transfer prices established by PEMEX, which reflect international market prices.

NOTE 18—FISCAL REGIME:

On December 21, 2005, the Mexican Congress approved a new fiscal regime for Petróleos Mexicanos and the Subsidiaries Entities, which was published in the Official Gazette of the Federation, effective January 1, 2006. This regime was modified on October 1, 2007 and again on November 13, 2008.

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS—(Continued)

FOR THE YEARS ENDED DECEMBER 31, 2009, 2008 AND 2007

(Figures stated in thousands of Mexican pesos, except as noted)

Under this new fiscal regime, PEMEX’s contribution scheme continues to be established by the Ley Federal de Derechos (Federal Duties Law) and the Ley de Ingresos de la Federación (Federal Income Law). The fiscal regime for PEMEX for 2009 contemplates the following duties:

(a) Ordinary Hydrocarbons Duty (“DOSH”)—During 2009 and 2008, the applicable rates of this duty were 73.50% and 74%, respectively. The computation of this duty is based on the value of the extracted total production of crude oil and natural gas during the year, minus certain permitted deductions established in the Federal Duties Law (including certain investments, costs, expenses and duties).

During 2009, Pemex-Exploration and Production made daily, weekly and monthly advance payments in the amounts of Ps. 160,630,027, Ps. 162,686,276, and Ps. 120,532,240, respectively, totaling Ps. 443,848,543, which amount was credited to the annual payment of the DOSH. During 2008, Pemex-Exploration and Production made daily, weekly and monthly advance payments in the amounts of Ps. 175,359,039, Ps. 183,755,212 and Ps. 340,347,198, respectively, totaling Ps. 699,461,449, which amount was credited to the annual payment of the DOSH.

In computing this duty, deductions derived from the residual value of investments made before the current fiscal regime took effect may be applied as a deferred deduction, referred to as a “temporary difference,” in accordance with FRS D-4. These deductions may be made in a maximum remaining period of ten years, the effect of which, if applied, can have a favorable effect in an amount up to approximately Ps. 271,226,118, depending on certain conditions established in the Federal Duties Law. To date, PEMEX has not recognized such effect from these deferred deductions because they are considered unlikely to materialize.

(b) Hydrocarbons Duty for the Stabilization Fund—Pemex-Exploration and Production must pay this duty when, during the applicable year, the weighted average Mexican crude oil export price exceeds U.S. $22.00. The applicable rate will be between 1% and 10%, depending on the weighted average price of crude oil exports, with the maximum rate of 10% applying when the price exceeds U.S. $31.00 per barrel. Collections of this duty are deposited in the Oil Revenues Stabilization Fund.

(c) Extraordinary Duty on Crude Oil Exports—This duty is calculated by applying a rate of 13.1% to the value resulting from multiplication of (i) the difference between the annual weighted average Mexican crude oil export price and the budgeted crude oil price as provided for in the Federal Income Law (U.S. $70.00 and U.S. $49.00 during 2009 and 2008, respectively), times (ii) the annual export volume. The duty actually paid may be credited against the Hydrocarbons Duty for the Stabilization Fund. Collections of this duty are directed to the Federative Entities through the Stabilization Fund for the Income of Federative Entities.

(d) Duty for Scientific and Technological Research on Energy—This duty is applied at a rate of 0.30% to the value of the extracted production of crude oil and natural gas for the year. The collections from this tax are directed as follows:

• 65% to the Sectorial Fund CONACYT of the Ministry of Energy for Hydrocarbons;

• 20% to the Scientific Research and Technological Development Fund of the Instituto Mexicano del Petróleo (Mexican Petroleum Institute, or “IMP”); and

• 15% to the Sectorial Fund CONACYT of the Ministry of Energy for Energy Sustainability.

(e) Duty for Oil Monitoring—This duty was applied at a rate of 0.003% to the value of extracted production of crude oil and natural gas for the year. The revenues from this tax are designated for the Auditoría Superior de la Federación (Supreme Federal Audit) in accordance with the Federal Expenditures Budget.

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS—(Continued)

FOR THE YEARS ENDED DECEMBER 31, 2009, 2008 AND 2007

(Figures stated in thousands of Mexican pesos, except as noted)

(f) Sole Hydrocarbons Duty—This duty is applied to the value of the extracted crude oil and natural gas from abandoned fields or fields that are in the process of being abandoned. The rate fluctuates between 37% and 57%, depending on the weighted average Mexican crude oil export price.

(g) Extraction of Hydrocarbons Duty—Effective November 14, 2008, this duty is applied to the value of the crude oil and natural gas extracted from the fields in Paleocanal de Chicontepec and in deep waters, at a floating rate between 10% and 20%, depending on the weighted average price per barrel of Mexican crude oil exports. Collections of this duty are deposited in the Oil Revenues Stabilization Fund.

(h) Special Hydrocarbons Duty for Paleocanal de Chicontepec fields (“Paleocanal de Chicontepec Duty”)—Effective November 14, 2008, this duty is applied at a rate of 71.5% to the value of the crude oil and natural gas extracted from the fields in the Paleocanal de Chicontepec, less certain deductions, which may not exceed the cost limit established in article 257 of the Federal Duties Law.

(i) Special Hydrocarbons Duty for Deep Water fields—Effective November 14, 2008, this duty is applied to the value of the crude oil and natural gas extracted from the fields in deep waters, less certain deductions, which may not exceed the cost limit established in article 257 of the Federal Duties Law. The applicable rate will be between 60% and 71.5%, depending on the weighted average price per barrel of Mexican crude oil exports.

(j) IEPS Tax—In accordance with current regulations, PEMEX is subject to the IEPS Tax, which applies to the importing and sale of gasoline and diesel. The IEPS is paid to the SHCP monthly, after deducting daily advance payments made in accordance with applicable rules. The effective rate of this tax depends on factors such as the type of product, reference price, the region where the product is sold, additional freight costs and applicable commissions.

In 2009, 2008 and 2007, increases in international prices of hydrocarbons and petroleum products caused the rate of the IEPS Tax to be negative. Effective January 1, 2006, the Federal Revenues Law was amended, allowing PEMEX to credit the negative IEPS Tax against other taxes and payments to which PEMEX is also subject. As a result of this credit, PEMEX recognized a benefit during 2009, 2008 and 2007 in other revenues of approximately Ps. 37,247,260, Ps. 194,575,700 and Ps. 72,137,000, respectively.

(k) Hydrocarbon Income Tax (“IRP”)—This tax is applicable to Petróleos Mexicanos and the Subsidiary Entities other than Pemex-Exploration and Production, and is calculated by applying a 30% rate on the excess of total revenues minus authorized deductions, pursuant to the specific rules provided by the SHCP in accordance with the Federal Income Law.

For the years ended December 31, 2009, 2008 and 2007, PEMEX generated an IRP as follows:

This tax will be declared through a tax form filed with the Federal Treasury no later than the last business day of March 2010, and the daily and weekly advance payments made during the fiscal year will be credited against that amount.

Petróleos Mexicanos will comply for its own account, and for the account of the Subsidiary Entities, with all obligations under the Federal Income Law and other fiscal laws, except as explicitly provided for in relation to the making of daily and weekly payments. As such, Petróleos Mexicanos will be solely responsible for the payment of contributions and duties owed by the Subsidiary Entities to the Mexican Government.

(l) Value Added Tax (“VAT”)—For VAT purposes, final monthly payments are determined in cash flow, in accordance with the provisions of the Value Added Tax Law, which is applicable to payers of this tax.

On November 25, 2009, the Federal Income Law was published in the Official Gazette of the Federation. Article 7, section III of that law provides for an additional procedure that applies exclusively to PEMEX, regarding treatment of the VAT in respect of imports of tangible goods. To be in compliance with this law, PEMEX recognized on December 31, 2009 a provision in the amount of Ps. 8,000,000.

(m) Income Tax—Certain of the Subsidiary Companies are subject to the Income Tax Law and to the IETU, and are therefore required to pay the greater of their IETU or Income Tax.

For the years ended December 31, 2009, 2008 and 2007, the Subsidiary Companies incurred the following income tax:

NOTE 19—NEW ACCOUNTING PRONOUNCEMENTS:

The CINIF has issued the following Mexican FRS that will take effect for fiscal years beginning as of January 1, 2010 or 2011, as indicated below:

(a) FRS B-5 “Financial Information by Segments”—This FRS will take effect as of January 1, 2011, and establishes the following principal changes as compared to Bulletin B-5 “Financial Information by Segment,” which it supersedes:

• It requires that information to be disclosed by operating segment be that which is regularly used by upper management, and establishes that such information need not be segregated into primary and secondary categories, nor refer to segments identified on the basis of particular goods or services (economic segments), geographic areas or homogeneous groups of customers. Additionally, it requires that the entity disclose aggregate information about its goods or services, geographical areas and main customers and suppliers.

• It does not require that, in order to qualify as operating segments, the entity’s business areas be subject to distinct types of risks.

• It permits the business areas to be classified as operating segments during the pre-operations phase.

• It requires the disclosure, by segment and separately, of interest income and expenses, as well as other components of the CFR. In certain situations, it permits disclosure of net interest income.

• It requires disclosure of the amounts of the liabilities included in the operating segment regularly used by upper management in making the entity’s operating decisions.

PEMEX’s management believes that the adoption of this new FRS will not have any material effects.

(b) FRS B-9 “Financial Information at Interim Dates”—This FRS will take effect as of January 1, 2011, and establishes the following principal changes as compared to Bulletin B-9 “Financial Information at Interim Dates,” which it supersedes:

• It requires that financial information at interim dates include, in condensed and comparative form, in addition to the statements of financial condition and of income, the statement of changes in shareholders’ equity and the statement of cash flows, as well as—in the case of non-profit entities—presentation of the statement of activities.

• It establishes that the financial information presented at the close of an interim period be presented comparatively with its equivalent interim period from the prior year, and, in the case of the balance sheet, that it also be compared with such financial statement as at year-end for the immediately preceding period.

• It incorporates and defines new terminology.

PEMEX’s management believes that the adoption of this new FRS will not have any material effects.

(c) FRS B-16 “Financial Statements of Non-Profit Entities”—This FRS will take effect as of January 1, 2010, and establishes the following principal changes as compared to Bulletin B-16 “Financial Statements of Non-Profit Entities,” which it supersedes:

• It establishes that donations received must be recorded as income.

• It defines the principal levels and classifications that must be presented on the statement of activities.

• It requires that cash and restricted cash equivalents be presented on the balance sheet under the heading “Cash and cash equivalents.”

• The term “temporary investments on demand” is replaced by the term “investments available on demand.”

• It includes, as a criterion for identifying investments available on demand, that they must be immediately available securities, such as investments with a maturity of no more than three months as of their acquisition date.

• It includes definitions of the following terms: “acquisition cost,” “cash equivalents,” “cash and restricted cash equivalents,” “investments available on demand,” “net realization value,” “par value” and “fair value.”

PEMEX’s management believes that the adoption of this FRS will not have any material effects.

(e) FRS E-2 “Donations Received or Given by Non-Profit Entities”—This FRS will take effect on January 1, 2010, and establishes the following principal changes as compared to Bulletin E-2 “Income and contributions received as well as made by non-profit entities,” which it supersedes:

• It uses the term “donation” in place of the term “contribution,” and the name of the standard is changed accordingly.

• It states that donations received are considered income.

• It uses, in the valuation of donations, the concepts of value established in FRS A­6 “Recognition and Valuation.”

• It establishes that collectibles (works of art, historical artifacts and similar assets) are not depreciated, but are subject to impairment.

• It establishes the classification of income from sale of goods or provision of services independently of whether their prices are below market prices.

• It eliminates the requirement of recognizing donations received in the form of services.

• It requires that, for purposes of recognizing unconditional promises to donate, they be accrued and be payable. It also requires estimation of the probable breach of unconditional promises that have been recognized and, if applicable, the cancellation of the related recognition of income.

• It requires that collectibles that have been acquired for purposes of being sold and obtaining funds be recognized at their cost or net realization value, whichever is less.

• Collectibles that the entity has acquired and plans to keep must be recognized, initially and subsequently, at their acquisition cost, and it is not permissible to make adjustments due to changes in their fair value, except in cases of impairment.

• The expense for donations made in the form of non-monetary assets must be recognized at the net book value of the donated asset.

PEMEX’s management believes that the adoption of this FRS will not have any material effects.

NOTE 21—DIFFERENCES BETWEEN MEXICAN FRS AND U.S. GAAP:

PEMEX’s consolidated financial statements are prepared in accordance with Mexican FRS, which differ in certain significant respects from U.S. GAAP. As described in Note 3(a) to these consolidated financial statements, until December 31, 2007, PEMEX recognized the effects of inflation on its financial information in accordance with FRS B-10, the guidelines of which are applied prospectively and do not require any adjustments for periods prior to January 1, 2008. For periods prior to January 1, 2008, all of the related U.S. GAAP adjustments have also been restated to reflect the effects of inflation. None of the adjustments to the financial statements for the effects of inflation required under Mexican FRS have been eliminated in the U.S. GAAP reconciliation for such periods.

Financial Accounting Standards Board (the “FASB”) Accounting Standards Codification^TM (the “Codification,” or “ASC”)

The Codification is the single source of authoritative generally accepted accounting principles (“GAAP”) recognized by the FASB to be applied by non-governmental entities in the preparation of financial statements in conformity with U.S. GAAP. Rules and interpretive releases of the U.S. Securities and Exchange Commission (the “SEC”) under authority of federal securities laws are also sources of authoritative GAAP for SEC registrants. The Codification became effective for interim and annual periods ending after September 15, 2009 and superseded all previously existing non-SEC accounting and reporting standards. All other non-grandfathered non-SEC accounting literature not included in the Codification is non-authoritative. All of PEMEX’s references to GAAP now use the Codification’s specific Accounting Standards Update (“ASU”), Topic or Subtopic, rather than prior accounting and reporting standards. The Codification did not change existing GAAP and, therefore, did not affect PEMEX’s financial position or results of operations.

I. Explanation of reconciling items:

(a) Exploration and drilling costs

Effective on January 1, 2004, for Mexican FRS purposes, PEMEX changed its accounting policy for the recognition of well exploration and drilling costs to the successful efforts method of accounting. Therefore, as of January 1, 2004, there has not been any related difference between Mexican FRS and U.S. GAAP.

PEMEX follows the successful efforts method of accounting, under which costs of drilling exploratory wells and exploratory-type stratigraphic test wells are initially capitalized and are later charged to expenses if proved reserves are not discovered. Development costs, including the costs of drilling development wells and development-type stratigraphic test wells, are capitalized. The capitalized costs of wells and related equipment are amortized on a UOP basis over proved developed reserves, as the related oil and gas reserves are extracted.

Consequently, as of December 31, 2009 and 2008, the U.S. GAAP equity adjustment represented the cumulative costs of capitalized unsuccessful wells in proven areas under U.S. GAAP, not capitalized under Mexican FRS through December 31, 2003, net of the amortization of such capitalized amounts. The 2009, 2008 and 2007 U.S. GAAP net loss adjustment reflects the amortization of such capitalized costs on a UOP basis.

ASC Topic 932-10-05 “Extractive Activities—Oil and Gas” (“Topic 932”) addresses the circumstances that would permit the continued capitalization of exploratory well costs beyond one year, other than when additional exploration wells are necessary to justify major capital expenditures and drilling of those wells is under way or firmly planned for the near future. Under the provisions of Topic 932, exploration costs would continue to be capitalized after the completion of drilling when (a) a quantity of reserves sufficient to justify completion as a producing well has been found in the well and (b) the enterprise is making sufficient progress assessing the reserves and the economic and operating viability of the project. If either condition is not met, or if an enterprise obtains information that raises substantial doubt about the economic or operational viability of the project, the exploratory well would be assumed to be impaired, and its costs, net of any salvage value, would be charged to expenses. Topic 932 provides a number of indicators that need to be present to demonstrate that sufficient progress has been made in assessing the reserves and the economic viability of the project.

PEMEX’s policy is to determine whether or not exploratory well costs are capitalized or expensed shortly after completion of drilling. As such, PEMEX does not have significant suspended well costs for the three years ended December 31, 2009. No capitalized exploratory well costs have been charged as expense since the adoption of Topic 932.

(b) Employee benefits

Under U.S. GAAP, PEMEX has recognized ASC Topic 715 “Compensation—Retirement Benefits” (“Topic 715”) and included its effects in the results of the actuarial valuation of its labor obligations.

Under Mexican FRS, PEMEX follows FRS D-3, which establishes the procedures for measuring the expenses and liabilities for pension plans, seniority premiums, and severance payments. The main differences between PEMEX’s application of FRS D-3 and the U.S. GAAP guidance that is now provided in Topic 715 regarding accounting for seniority premiums, pensions, health services and other supplemental payments provided to retirees and other eligible family members are summarized as follows:

(c) Accrued vacations

Under Mexican FRS, PEMEX recognizes vacation expenses when the vacations are utilized by its employees. Under U.S. GAAP, vacation expense is accrued when it is earned by the employee.

(d) Fixed assets—Capitalized gains and losses of derivative financial instruments

Under Mexican FRS, finance costs related to loans allocated to construction projects are capitalized as part of capitalized interest, and are included net of gains and losses arising from DFIs designated as hedges.

Under ASC Subtopic 815-25-35 “Derivatives and Hedging—Fair Value Hedges—Subsequent Measurements,” gains and losses arising from financial instruments designated as cash flow hedges cannot be capitalized as part of qualifying assets. These amounts are accumulated in other comprehensive income and are reclassified into earnings over the life of the assets to which the hedged transaction relates.

Through December 31, 2008, the Master Trust and Fideicomiso F/163 issued debt securities through inter-company private placements to Petróleos Mexicanos for the purpose of funding PIDIREGAS-related projects. As discussed in Note 2, amendments to the Federal Law of Budget and Fiscal Accountability became effective in November 2008. Effective January 1, 2009, in connection with these amendments, Petróleos Mexicanos assumed primary responsibility for the payment of all indebtedness of the Master Trust and Fideicomiso F/163, respectively. However, the Master Trust and Fideicomiso F/163, as applicable, continued to act as servicer of all indebtedness until Petróleos Mexicanos legally assumed, as primary obligor, their indebtedness under the related agreements. These legal assumptions were carried out during the second half of 2009. In addition, all of these inter-company private placements were canceled effective January 30, 2009, as a result of the changes to the Federal Law of Budget and Fiscal Accountability. These financings had been hedged through DFIs, but in connection with the amendments described above, PEMEX decided to remove such designation and discontinue the hedging activities of those derivatives related to PIDIREGAS financings. Accordingly, for the year ended December 2009, there was no capitalized gain or loss adjustment related to cash flow hedge derivatives covering the financings entered into for infrastructure projects.

For the years ended December 31, 2008 and 2007, the capitalized loss adjustments in the reconciliation were Ps. 1,163,278 and Ps. 19,439, respectively, arising from hedging instruments.

The 2009, 2008 and 2007 net loss adjustments also include a depreciation effect of Ps. 110,586, Ps. 157,117 and Ps. 157,895, respectively, related to amounts previously capitalized.

(e) Fixed assets—Capitalization of interest

Effective January 1, 2007, PEMEX adopted FRS D-6 “Capitalization of Comprehensive Financing Result,” which establishes the rules that must be observed in the capitalization of the CFR attributable to certain assets, whose acquisition required a substantial (prolonged) period before their intended use.

The capitalized CFR is composed of interest cost, the foreign exchange effect and other costs associated with obtaining financing identified with qualifying assets, which directly affect the investment cost during the acquisition period. For periods ending prior to January 1, 2008, the result in monetary position is also included.

Under U.S. GAAP, prior to 2007, a portion of debt generated interest that was capitalized by applying an average interest rate to the average amount of accumulated expenditures for the qualifying asset during the

period. However, until the adoption of FRS D-6, the accounting criteria under Mexican FRS differed in this regard. PEMEX has accordingly adjusted its results of operations and equity to reflect the U.S. GAAP requirements for capitalizing interest.

Interest costs and the foreign exchange effect for the years ended December 31, 2009, 2008 and 2007, for Mexican FRS and U.S. GAAP purposes, were allocated as follows:

	2009		2008		2007
Under Mexican FRS:
Interest and foreign exchange fluctuation capitalized	Ps.	2,054,190	Ps.	1,057,440	Ps.	5,350,849
Interest expense		78,300,095		73,883,856		57,847,569
Total interest cost and foreign exchange fluctuation	Ps.	80,354,285	Ps.	74,941,296	Ps.	63,198,418
Under U.S. GAAP:
Interest capitalized	Ps.	3,813,746	Ps.	559,607	Ps.	7,797,815
Interest expense and foreign exchange fluctuation		76,540,539		74,381,689		55,400,603
Total interest cost and foreign exchange fluctuation	Ps.	80,354,285	Ps.	74,941,296	Ps.	63,198,418

During 2009, the only difference between Mexican FRS and U.S. GAAP was the net foreign exchange effect of Ps. 1,759,556 capitalized under Mexican FRS.

In addition, the net income adjustments for capitalized interest presented herein also include a depreciation effect of Ps. 941,818, Ps. 980,800 and Ps. 1,062,994 for the years ended December 31, 2009, 2008 and 2007, respectively, related to the cumulative difference in amounts previously capitalized for such assets because the cumulative amounts capitalized under Mexican FRS have exceeded those amounts under U.S. GAAP.

(f) Fixed assets—Impairment

For Mexican FRS purposes, as described in Note 3(i), PEMEX evaluates the impairment of long-lived assets whenever there are events or circumstances indicating that the book value of a given asset may not be recoverable under Bulletin C-15.

For each of the cash-generating units, if the book value of the long-lived assets exceeds the estimated future value (discounted) of cash flows recoverable by such long-lived assets, a charge is made to income for the period for an impairment loss. PEMEX performs this calculation at least annually. In accordance with Bulletin C-15, the impairment recorded can be reversed in subsequent periods if the subsequent impairment analysis does not indicate a loss in such future periods.

For U.S. GAAP purposes, an evaluation of impairment is undertaken whenever events or circumstances indicate that the carrying amount of an asset may not be recoverable, as is the case under Mexican FRS. However, under U.S. GAAP, the impairment criteria are met when the carrying value of assets exceeds the sum of expected future cash flows (undiscounted and without financing charges) of the related assets. The asset is written down to fair value as determined by using the present value of expected future cash flows. U.S. GAAP does not allow for reversal of losses; PEMEX measures impairment of its oil and gas producing assets based on the undiscounted estimated future cash flows associated with estimated proved reserves on a field-by-field basis.

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS—(Continued)

FOR THE YEARS ENDED DECEMBER 31, 2009, 2008 AND 2007

(Figures stated in thousands of Mexican pesos, except as noted)

In determining the estimated future cash flows for impairment purposes for all periods presented, hydrocarbon duties based on sales to third parties have not been included in the net cash flows calculation for either Mexican FRS or U.S. GAAP. PEMEX’s management believes that the hydrocarbon duties paid are similar in nature to income taxes or dividend distributions payable to a parent, and therefore are properly excluded from the net cash flow calculation.

Under Mexican FRS, Bulletin C-15 became effective on January 1, 2004. Prior to this bulletin becoming effective, under U.S. GAAP, PEMEX would recognize an impairment charge in the U.S. GAAP net (loss) income reconciliation. During 2009 and 2008, PEMEX recognized an impairment charge under Mexican FRS of Ps. 1,731,229 and Ps. 807,050, respectively. Because the assets related to the 2008 Mexican FRS impairment charge had already been impaired under U.S. GAAP, these charges have been reversed for U.S. GAAP purposes. During 2007, there was no impairment under Mexican FRS. The 2009, 2008 and 2007 U.S. GAAP net income reconciliation also includes a credit of Ps. 2,413,928, Ps. 3,094,290 and Ps. 3,344,517, respectively, for depreciation due to the difference in carrying values of long-lived assets between Mexican FRS and U.S. GAAP. In addition, the 2008 U.S. GAAP net loss reconciliation includes a debit of Ps. 699,847, because the impairment reversal accounted for under Mexican FRS during 2008 is not permitted under U.S. GAAP.

(g) Fixed assets—Depreciation convention

Until 2002, under PEMEX’s accounting policies, assets would begin to depreciate in the year after which they were placed in service. Under U.S. GAAP, however, assets are depreciated from the date they were placed in service. Beginning in 2003, PEMEX prospectively changed its accounting policies requiring depreciation from the month after the asset was placed into service, thereby eliminating any differences between Mexican FRS and U.S. GAAP for assets placed in service in 2003 and later years. The 2007 U.S. GAAP adjustments reflect a credit to income of Ps. 783,144 for the reversal of the depreciation expense previously recorded under U.S. GAAP for assets placed in service before 2003. Commencing January 1, 2008, no reversal of the depreciation expense previously recorded for assets placed in service before 2003 is required.

(h) Accounting for derivative financial instruments and fair value measurements

Derivative financial instruments (DFIs)

For U.S. GAAP purposes, PEMEX applies ASC Topic 815 “Derivatives and Hedging” (“Topic 815”), which requires that all derivative instruments (including certain derivative instruments embedded in other contracts) be recognized in the balance sheet as assets or liabilities at their fair values and that changes to fair values be recognized immediately in earnings, unless the derivative qualifies as a “hedge” (as defined in Topic 815), for which certain special accounting treatment is permitted.

In accordance with U.S. GAAP, hedge effectiveness is assessed consistently with the method and risk management strategy documented for each hedging relationship. PEMEX assesses the effectiveness of each hedging relationship prospectively and retrospectively to ensure that the application of hedge accounting treatment was appropriate at the designation date, and continues to be appropriate for subsequent future periods. PEMEX considers hedge accounting to be appropriate if the assessment of hedge effectiveness indicates that the change in fair value of the designated hedging instrument is highly effective at offsetting the change in fair value or cash flow variability due to the hedged risk of the hedged item or transaction.

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS—(Continued)

FOR THE YEARS ENDED DECEMBER 31, 2009, 2008 AND 2007

(Figures stated in thousands of Mexican pesos, except as noted)

If a derivative instrument qualifies as a fair value hedge, the change in the fair value of the derivative and the change in the fair value of the hedged item that is due to the hedged risks are recorded in earnings based on the income classification of the item being hedged. These hedges also adjust the book values of the derivatives and hedged items.

If a derivative instrument qualifies as a cash flow hedge, the effective portion of the hedging instrument’s gain or loss is reported as stockholders’ equity (as a component of AOCI) and is reclassified into earnings in the period during which the transaction being hedged affects earnings. Effective gains or losses reclassified from stockholders’ equity to earnings are classified in accordance with the earnings treatment of the hedged transaction. The ineffective portion of the hedging instrument’s gain or loss is recognized in the statement of operations in the CFR. If a derivative instrument does not qualify as a hedge under the applicable guidance, the change in the fair value of the derivative is immediately recognized in the statement of operations in the CFR.

PEMEX also evaluates contracts for “embedded” derivatives, and considers whether any embedded derivatives have to be bifurcated or separated from the host contracts in accordance with Topic 815 requirements. Embedded derivatives may have terms that are not clearly and closely related to the terms of the host contract in which they are included. If embedded derivatives exist that are not clearly and closely related to the host contract or include either leverage features or exposure to the substantial loss of the principal in the case of structured products, they are accounted for separately from the host contract as freestanding derivatives, with changes in their fair value recorded in current earnings in the CFR to the extent that the hybrid instrument is not already recorded at fair value with changes in fair value recorded in earnings.

When hedge accounting is discontinued under the fair value hedge accounting model due to PEMEX’s determination that the derivative no longer qualifies as an effective fair value hedge, PEMEX will continue to carry the derivative on the balance sheet at its fair value with changes in fair value recorded in earnings under the CFR item. The related hedged asset, liability or firm commitment will cease to be adjusted for changes in fair value that are due to the previously hedged risk and subsequent interest accrual will be recognized based on the new effective interest yield or funding cost, taking into account the fair value hedge adjustment amount as of the termination date of the hedge relationship. When PEMEX discontinues hedge accounting in a cash flow hedge relationship, because it is no longer probable that the forecasted transaction will occur in the originally expected period or within two months, the effective gain or loss on the derivative remaining in AOCI is reclassified immediately into earnings; if a derivative instrument ceases to meet the criteria for hedge accounting, any subsequent gains or losses are recognized in current earnings and the effective portion, as of the date the cash flow hedge relationship ceased to exist, is recorded in earnings based on where the hedged item had an effect, in the amount needed to achieve the effective yield or funding cost provided by the derivative while the hedged item still impacts earnings.

The remaining adjustment of the carrying amount of a fair value hedged asset, liability or firm commitment will remain part of the carrying amount of that asset, liability or firm commitment until the asset or liability is sold or written off, the liability expires, is paid or transferred or the firm commitment ceases to exist. In fair value hedges, an adjustment of the carrying amount of a hedged interest-bearing financial instrument will be amortized to earnings as part of the new effective yield; amortization will begin no later than when the hedged item ceases to be adjusted for changes in its fair value attributable to the risk being hedged.

For Mexican FRS purposes, effective on January 1, 2005, PEMEX adopted the provisions of Bulletin C-10. Bulletin C-10 contains provisions similar to those of Topic 815, and provides expanded guidance for the

F-69

(Figures stated in thousands of Mexican pesos, except as noted)

recognition, valuation, accounting treatment and disclosure applicable to DFIs, such as hedges and embedded derivatives, including the need for contemporaneous hedge documentation and effectiveness testing requirements.

Similar to the requirements under U.S. GAAP, contracts need to be assessed for embedded derivatives with such derivatives needing to be bifurcated from the host contracts under certain conditions and recognized at fair value with fluctuations recognized in earnings. For Mexican FRS purposes, PEMEX, in accordance with Bulletin C-10, recognized embedded derivatives within several contractual agreements related to, among other things, services in connection with construction projects, acquisitions, leases and insurance commitments. These agreements were entered into by PEMEX and denominated in foreign currencies and, in accordance with their terms, the related foreign currency components generate embedded derivatives, but these embedded derivatives are not required to be bifurcated from the host contracts under Bulletin C-10, because the agreements do not meet the net settlement criteria. For U.S. GAAP purposes, foreign currency embedded derivatives in either recognized financial instruments or non-recognized contractual agreements are bifurcated from host contracts when the payments under such contracts are not denominated in one of the functional currencies of either of the counterparties.

Therefore, as of December 31, 2009, there are differences between Mexican FRS and U.S. GAAP related to accounting for derivative instruments and hedging activities (including embedded derivatives attributable to an embedded non-functional currency component). Additionally, U.S. GAAP allows for non-effectiveness testing associated with the use of interest rate swaps when they meet certain general and particular conditions in designated hedging relationships (known as the “short-cut method criteria”).

As a result of the above, PEMEX has recognized a U.S. GAAP adjustment for the years ended December 31, 2009, 2008 and 2007, representing a net gain (loss) of Ps. 11,862,782, Ps. (15,188,098) and Ps. (8,149,706), respectively, reported in the CFR in the consolidated statements of operations.

For the years ended December 31, 2009, 2008 and 2007, PEMEX recognized a net gain (loss) of Ps. 2,532,882, Ps. (1,268,722) and Ps. 656,699, respectively, reported as “derivative financial instruments” in the consolidated other comprehensive income (loss) statement under U.S. GAAP.

As to permissible exclusions under both Mexican FRS and U.S. GAAP, for hedge effectiveness testing on formalized hedge relationships, PEMEX uses all components of each derivative’s gain or loss that were included in the assessment and measurement of hedge effectiveness, except for the time value (extrinsic value changes) in the case of option contracts. The time value exclusion effect with respect to options-based hedges is reflected in the CFR within earnings.

PEMEX’s DFIs portfolio does not contain any exotic instruments whose valuation would require reference to parameters or inputs, i.e., parameters that cannot be implied from liquid instruments readily observable in the financial markets.

The valuation of PEMEX’s DFIs portfolio is based on market information obtained from established independent sources of market prices, as well as pricing information provided by the major world trading markets, including the New York Mercantile Exchange (“NYMEX”) and the Chicago Board of Trade (“CBOT”).

Fair value measurements

Additionally, for U.S. GAAP purposes, PEMEX applies ASC Topic 820 “Fair Value Measurement and Disclosures” (“Topic 820”), which defines fair value, establishes a framework for the measurement of fair value and enhances disclosure about fair value measurements.

In accordance with Topic 820, PEMEX values its DFIs under standard methodologies commonly applied in the financial markets. PEMEX’s related assumptions therefore fall under Level 2 of the Topic 820 fair value hierarchy for market participant assumptions.

Pursuant to the provisions of Topic 820, fair values determined by Level 1 inputs utilize quoted prices in active markets for identical assets or liabilities. Fair values determined by Level 2 inputs are based on quoted

prices for similar assets or liabilities in active markets, and inputs other than quoted prices that are observed for assets or liabilities. Level 3 inputs are unobservable inputs for the assets or liabilities, and include situations where there is little, if any, market activity for the assets or liabilities. Management uses appropriate valuation techniques based on the available inputs to measure the fair values of PEMEX’s applicable assets and liabilities.

When available, PEMEX measures fair value using Level 1 inputs, because they generally provide the most reliable evidence of fair value.

PEMEX periodically evaluates its exposure to international hydrocarbon prices, interest rates and foreign currencies, and uses derivative instruments as a mitigation mechanism when potential sources of market risk are identified.

The following table presents information about PEMEX’s assets and liabilities measured at fair value, and indicates the fair value hierarchy of the inputs utilized to determine the fair values as of December 31, 2009. PEMEX’s accounting for these assets and liabilities was impacted by the adoption of Topic 820 as described below.

For the year ended December 31, 2009, PEMEX has recognized a net loss of Ps. 1,648,565 as the credit risk adjustment required by Topic 820 on the fair value of PEMEX’s DFIs, reported in the CFR in the consolidated statements of operations.

(Figures stated in thousands of Mexican pesos, except as noted)

The valuation methods used to measure PEMEX’s financial instruments’ fair value include (1) obtaining directly comparable market quotes from major market sources, and (2) where directly comparable quotes are not available, calculating fair value based on quotes from major market sources which are then adjusted internally using standard market pricing models for interest rate, currency, equity and commodities derivatives.

The estimated fair value of financial assets and liabilities, as of December 31, 2009 and 2008, in nominal terms, was as follows:

	2009				2008
	Carrying Value		Fair Value		Carrying Value		Fair Value
Assets:
Cash and cash equivalents	Ps.	128,179,628	Ps.	128,179,628	Ps.	114,224,395	Ps.	114,224,395
Accounts, notes receivable and other		158,336,065		158,336,065		162,309,939		162,309,939

Accounts and accumulated expenses payable		11,590,917		11,590,917		7,970,593		7,970,593
Taxes payable		48,453,301		48,453,301		16,672,511		16,672,511
Current portion of long-term debt		102,600,324		102,600,324		91,223,879		91,223,879
Long-term debt		529,258,434		495,590,992		495,486,625		475,496,718

Pursuant to Topic 820, the fair values of the financial assets and liabilities presented in the table above appear for informational purposes, and they fall under Level 2 of the Topic 820 fair value hierarchy.

The fair values of financial assets and short-term liabilities are estimated as a proportion of their nominal values, due to short-term maturities yielding nominal values that are very close to their corresponding fair values.

The fair value of long-term debt is estimated using quotes from major market sources, which are then adjusted internally using standard market pricing models. As a result of relevant assumptions, estimated fair values do not necessarily represent the actual terms at which existing transactions could be liquidated or unwound.

Pursuant to ASC Topic 360 “Property, Plant and Equipment” (“Topic 360”), PEMEX reviews property for impairment when events and circumstances indicate a possible decline in the recoverability of the carrying value of such property. PEMEX estimates the future cash flows expected in connection with the property and compares such future cash flows to the carrying amount of the property to determine if the carrying amount is recoverable. If the carrying amount of the property exceeds its estimated undiscounted future cash flows, the carrying amount of the property is reduced to its estimated fair value. Fair value may be estimated using comparable market data, a discounted cash flow method, or a combination of the two. In the discounted cash flow method, estimated future cash flows are based on management’s expectations for the future and include estimates of future oil and gas production, commodity prices based on published forward commodity price curves as of the date of the estimate, operating and development costs, and a risk-adjusted discount rate.

(1) Amount represents the fair values of the impaired properties as of December 31, 2009. See Note 9—Wells, Pipelines, Properties, Plant and Equipment for additional information.

(i) Profit in inventory

Until December 31, 2007, under Mexican FRS, PEMEX valued crude oil and derivatives for export at realizable value, with the difference between the realizable value and cost recorded in earnings. In contrast, U.S. GAAP requires that inventories be recorded at the lower of cost or market value. For U.S. GAAP equity reconciliation purposes, PEMEX has eliminated the effect of recognizing a profit within its ending inventory balance at each period end. For net (loss) income reconciliation purposes, the adjustment for 2008 reflects the reversal of the prior year’s equity adjustment as inventory was sold. As of January 1, 2008, there is no longer a difference between Mexican FRS and U.S. GAAP with respect to inventory valuation.

(j) Accounting for available-for-sale securities (Repsol)

Pursuant to ASC Topic 320 “Investments—Debt and Equity Securities” (“Topic 320”), PEMEX classifies its investment securities as “available-for-sale” and, accordingly, they are recorded at fair value with unrealized gains and losses excluded from the statement of operations and reported in other comprehensive (loss) income. The fair value of the securities is determined by reference to quoted market prices at December 31, 2009, 2008 and 2007. An impairment loss is recognized when the loss is considered other than temporary.

Under Mexican FRS, these investment securities are also recorded at fair value, but the unrealized gains and losses are reflected in earnings. The income (loss) adjustments for the years ended December 31, 2008 and 2007 reflect the reversal of the fair value adjustment to earnings as reflected under Mexican FRS, because U.S. GAAP requires such adjustment to be reflected in other comprehensive (loss) income.

(k) Effects of inflation on the U.S. GAAP adjustments

For the year ended December 31, 2007, various U.S. GAAP adjustments included herein are adjustments to monetary assets and liabilities recorded under Mexican FRS pursuant to FRS B-10, as described in Note 3(a). Therefore, the adjustments to the balance would also result in an adjustment to the monetary gain or loss as reported under Mexican FRS for the year then ended. Effective on January 1, 2008, no U.S. GAAP adjustments were made to the monetary assets and liabilities recorded under Mexican FRS pursuant to FRS B-10.

(l) Deferred income taxes

As described in Note 18, during 2005, a new fiscal regime was enacted that became applicable to Petróleos Mexicanos and its Subsidiary Entities effective January 1, 2006. Due to the related change in tax regime, Petróleos Mexicanos and its Subsidiary Entities began recognizing deferred income taxes during 2005. The U.S. GAAP equity adjustment represents the cumulative impact of deferred income taxes relating to the other U.S. GAAP adjustments applicable to Petróleos Mexicanos and its Subsidiary Entities.

(m) Non-controlling interest

Effective July 1, 2005, PEMEX entered into an option agreement with BNP Paribas Private Bank and Trust Cayman Limited to acquire 100% of the shares of Pemex Finance, Ltd. (“Pemex Finance”). As a result, since 2005, the financial results of Pemex Finance have been consolidated into the financial statements of PEMEX for Mexican FRS purposes. Historically, Pemex Finance has been consolidated in the accompanying condensed consolidated U.S. GAAP information included herein for all periods presented. However, under U.S. GAAP, net income and retained earnings from Pemex Finance are reclassified as non-controlling interest due to the fact that PEMEX does not currently own any of the shares of Pemex Finance. The U.S. GAAP adjustment related to Pemex Finance represents the reclassification of net income and equity recognized under Mexican FRS to non-controlling interest.

(n) Sale of shares of Repsol

As discussed in Notes 8 and 11, during 2008, PEMEX’s subsidiary RepCon Lux redeemed its bonds exchangeable for Repsol shares representing approximately 4.81% of Repsol’s share capital. PEMEX entered into four related equity swaps with financial institutions, monetizing the value of 58,679,799 shares. PEMEX thereby retained the economic and voting rights in respect of those shares, utilizing the proceeds of the swaps to liquidate the exchangeable bonds.

II. Additional disclosure requirements:

(a) Consolidation of Pemex Finance

PEMEX and certain of its subsidiaries have entered into several agreements with Pemex Finance, under which Pemex Finance purchases existing accounts receivable and rights to future receivables from certain customers. Pemex Finance obtains resources for such purchases through the placement of debt instruments in the international markets, as well as from the recurring returns on its investments. Since 2005, the financial results of Pemex Finance have been consolidated in the financial statements of PEMEX under Mexican FRS.

Under ASC Topic 860 “Transfers and Servicing” (“Topic 860”), PEMEX has evaluated the Pemex Finance structure in light of the permitted and non-permitted activities of a Qualified Special Purpose Entity (“QSPE”), and has determined that Pemex Finance does not qualify as a QSPE, and should therefore be consolidated for U.S. GAAP purposes. Consequently, Pemex Finance has been consolidated in the accompanying condensed consolidated U.S. GAAP information included herein for all periods presented; however, its net income and equity recognized under Mexican FRS are reclassified as non-controlling interest, as described in Note 21 I(m).

(b) IEPS Tax

Under Mexican FRS, the IEPS Tax is reflected as part of net domestic sales when charged to customers and the amounts payable to the Mexican Government are then deducted from income before hydrocarbon extraction duties and other, special taxes on production and services, and cumulative effect of adoption of new accounting standards.

FOR THE YEARS ENDED DECEMBER 31, 2009, 2008 AND 2007

(Figures stated in thousands of Mexican pesos, except as noted)

Under U.S. GAAP, this tax would have no net effect on revenues nor would it be deducted from income before taxes and duties, net of IEPS tax, as both the amount charged to customers and the amount accrued as payable to the tax authorities would be excluded from revenues (i.e., there is no gross-up).

(c) Environmental, dismantlement and abandonment liabilities

PEMEX establishes accruals for its environmental liabilities using estimates based on costs of similar remediation works most recently contracted and in progress at that time.

PEMEX has internal guidelines for estimating and recording environmental liabilities, the Guía para la Determinación de las Provisiones y Revelaciones de Carácter Ambiental (Guidelines for the Determination of Environmental Liabilities and their Disclosure). These guidelines’ purpose is to standardize and improve PEMEX’s internal procedures for identifying necessary remediation works and estimating and monitoring environmental liabilities.

These guidelines establish that an environmental liability exists when:

(i) as a result of the activities of PEMEX, an affected area is identified in a particular site, and PEMEX undertakes a formal commitment to correct the environmental deficiency, in accordance with the criteria, guidelines, standards and legal framework in effect; and

(ii) a reasonable estimate of the costs of remediation or cleanup of the identified affected area has been made, including the costs of the assessment studies.

As stated above, in accordance with past and present internal guidelines, PEMEX conducts site-by-site studies to identify environmental liabilities and develop a reasonable estimate of such liabilities. These guidelines consider many factors, but are tailored to specific Mexican requirements. Each contaminated site must be characterized, quantified and assessed through a specific study. The contamination of the affected sites may extend to the soil, subsoil and bodies of water, including water deposits, lagoons, swamps and others. These sites may be located inside PEMEX’s facilities, in surrounding areas, in abandoned areas where PEMEX had activity in the past or along the pipelines.

Once the corresponding contaminated site has been identified and evaluated, expenses for the cleanup of (i) hydrocarbon seepage and other spills that may cause pollution and that cannot be corrected in a short timeframe, (ii) water deposits and (iii) the concentration of hazardous residuals will be included in the remediation or restoration of affected areas. Estimates are kept current based on the best available information.

Based on reports from field managers and other available information, management prepares reports for identified affected areas on a periodic basis. When the contamination relates to a new incident, PEMEX informs PROFEPA and responds immediately to eliminate the cause of the incident or to minimize its impact. Subsequently, PEMEX and PROFEPA jointly determine whether the contamination has been eliminated or if additional actions are necessary for the remediation of the site.

PEMEX believes its environmental liabilities are probable when its initial studies reveal the existence of contamination in the inspected areas at levels above those permitted by Mexican law, indicating that PEMEX will have to perform remediation works necessary to bring the site into compliance. PEMEX believes the liability is reasonably estimable when (i) an assessment of the size of the affected area has been made, (ii) it has compared the affected area to other affected areas identified and addressed in the past and (iii) based on

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS—(Continued)

FOR THE YEARS ENDED DECEMBER 31, 2009, 2008 AND 2007

(Figures stated in thousands of Mexican pesos, except as noted)

PEMEX’s experience with current or recent activities on similar sites, PEMEX can assess the estimated remediation costs in order to be able to calculate the corresponding environmental liability. Thus, PEMEX accrues for these environmental liabilities when it identifies affected areas with contamination levels above those permitted by Mexican law and PEMEX is able to make a reasonable estimate of the size of the affected area and the remediation cost. In addition, PEMEX periodically revises its estimates of environmental liabilities as it obtains new information during the course of the remediation works, in order to ensure that its estimates are based on the most accurate and updated information.

PROFEPA administers the Mexican environmental regulatory rubric and establishes acceptable standards of environmental remediation. Although PROFEPA has the authority to review and inspect remediation works performed by PEMEX and compliance with permitted contamination levels established by laws and regulations, it does not determine PEMEX’s environmental liabilities. PEMEX maintains proper records of all of the studies, estimations, performed works and any other information that PROFEPA may request from time to time.

During 2009, 2008 and 2007, PEMEX spent Ps. 5,643,069, Ps. 4,254,586 and Ps. 4,120,000, respectively, on various environmental projects and related expenditures. The most significant projects have included the modernization of installations, the implementation of systems and control mechanisms to monitor atmospheric pollution, the acquisition of equipment to clean hydrocarbon spills, the expansion of aquatic effluent systems, the restoration and reforestation of affected areas, environmental investigative studies and the conducting of environmental audits. In addition, PEMEX has engaged in extensive research and development efforts to develop capacity for increased production of unleaded gasoline, diesel and fuel oil with lower sulfur content and alternative fuels, such as industrial oil gas and natural gas.

PEMEX’s management believes that its operations are in substantial compliance with the General Law on Ecological Equilibrium and Environmental Protection (the “Environmental Law”), as such law has been historically interpreted and enforced.

Environmental expenditures are expensed or capitalized depending on their future economic benefit. Expenditures that relate to an existing condition caused by past operations that have no future economic benefit are expensed. Liabilities for expenditures of a non-capital nature are recorded on a discounted basis when (a) expenses include payments during periods longer than one year, (b) environmental assessment and/or remediation is probable and (c) the costs can be reasonably estimated.

Because PEMEX has exclusive rights over production and processing of crude oil, natural gas and refined products within Mexico, there are no instances of joint liability; PEMEX is the sole responsible party in the event of environmental damage. PEMEX obtains insurance policies to cover the cost of certain environmental contingencies. The liability accruals are not reflected net of any amounts forthcoming under such policies. Environmental liabilities accrued in the consolidated financial statements, for both Mexican FRS and U.S. GAAP purposes, as of December 31, were divided among the operating units as follows:

	2009		2008
Pemex-Exploration and Production	Ps.	2,398,560	Ps.	269,703
Pemex-Refining		3,605,870		1,371,819

(d) Dismantlement and abandonment costs

Under current Mexican law, PEMEX’s legal obligation related to dismantlement and abandonment activities is governed by the following two federal laws: the Petroleum Works Law and the Environmental Law described in this Note. Although PEMEX is subject to other laws and regulations established at a local level in areas where PEMEX undertakes petroleum extraction activities, these local laws and regulations do not contain any specific guidance on abandonment, restoration and removal of oil and gas facilities, or otherwise impose a higher standard on PEMEX in this regard. Mexico is not a party to any international treaty or convention that would affect PEMEX’s understanding of its obligation with regard to dismantlement and abandonment activities. Thus, the only relevant body of law for PEMEX as to abandonment and removal of facilities related to oil- and gas-producing activities is Mexican federal law.

The Petroleum Works Law provides that wells must be plugged, or in certain cases, capped, to ensure the maintenance of sanitary and safe conditions and to prevent the seepage of hydrocarbons to the surface. The Petroleum Works Law requires that PEMEX plug a well when it turns out to be dry, is invaded with salt water or is abandoned due to a mechanical accident, or once a well’s production has been depleted such that abandonment is necessary due to economic unfeasibility of production. All activities required for plugging a well are undertaken with the purpose of isolating, in a definitive and convenient manner, the cross-formations in the perforation that contain oil, gas or water in order to ensure that hydrocarbons do not seep to the surface.

PEMEX must obtain authorization from the Ministry of Energy before performing any plugging activities. The Petroleum Works Law also provides that the Ministry of Energy may authorize temporary plugging of exploratory wells where production of hydrocarbons is commercially feasible, but for which there are no adequate means of exploitation.

PEMEX monitors and reviews its own internal estimates of costs to undertake dismantlement and abandonment at levels consistent with Mexican legal requirements and guidelines for oil and gas industry extraction activities. Estimates as to aggregate costs include PEMEX’s operational specifics such as the number of onshore and offshore wells, depth of wells, the varying nature of offshore platforms, expected production lives, current expectations as to when the costs will be incurred based on present production rates and other operational specifics. The actual costs incurred in the dismantlement and retirement of wells are considered where practicable, as described above. The average cost for plugging and dismantlement varies from producing region to producing region and from platform to platform. For the offshore regions, to the extent that actual costs are not available due to limited plugging and dismantlement activity historically, PEMEX relies on estimates based on services costs. The estimated costs are both peso- and U.S. dollar-denominated.

(e) Employee benefits

Disclosures of classifications of employee benefits determined in accordance with U.S. GAAP have been presented, for purposes of comparison, in a format consistent with Mexican FRS requirements.

(Figures stated in thousands of Mexican pesos, except as noted)

Actuarial assumptions, expressed in nominal rates, used in the calculation of employee benefits plan cost under U.S. GAAP as of December 31, 2009, 2008 and 2007, were as follows:

	2009			2008			2007
Discount rate	8.	75	%	8.	75	%	8.	42	%
Rate of increase in compensation levels	5.	50	%	5.	00	%	4.	52	%
Expected long-term rate of return on assets	8.	75	%	8.	50	%	8.	42	%
Health care cost trend rate	5.	93	%	5.	50	%	5.	56	%

The calculation of employee benefits plan cost under Topic 715 requires considerable judgment with respect to choosing actuarial assumptions. Each significant assumption reflects PEMEX’s best estimate of the plan’s future performance solely with respect to that assumption. Assumed discount rates and compensation levels often have the greatest effect on employee benefits plan cost, and are related, because both are affected by some of the same economic factors. The discount rate is based upon the current prices for settling the pension obligation, referred to as the “settlement rate,” and the current yield on high quality corporate bonds (AA or better) of term and currency consistent with the benefit obligation as of the measurement date. According to the external actuary, assumed compensation levels reflect PEMEX’s estimate of actual future compensation levels for the individuals involved and are consistent with assumed discount rates to the extent that both incorporate expectations of the same future economic conditions.

PEMEX makes supplemental payments in respect of its obligations for gas, gasoline and basic food supplies, and provides healthcare benefits, in each case to retired employees and their immediate family members. PEMEX regularly adjusts the level of its supplemental payments based on inflationary conditions. Healthcare is provided through a regional network of PEMEX hospitals and medical centers, which also provide care to active PEMEX employees. No commitments have been made regarding the level of such contributions in the future.

Payments charged to the reserve for medical and hospital services for retired personnel and pension recipients in 2009 and 2008 were Ps. 4,260,829 and Ps. 4,039,137, respectively.

The expected timing of payments of employee benefits according to the plans in each of the next ten years, through 2019, is as follows:

Year	Retirement and Termination Expected Benefit Payment		Post-retirement Expected Benefit Payment
2010	Ps.	57,362,238	Ps.	37,657,960

(Figures stated in thousands of Mexican pesos, except as noted)

The objective of PEMEX’s investment guidelines with respect to its plan assets is to ensure the highest security together with an adequate rate of return, maintaining the purchasing power of the investments. The comparative benchmark used by PEMEX is the monthly average of primary interest rates of Mexican Government 28-day Treasury bills (“Cetes 28”).

The investment guidelines list certain prohibited investments, such as: securities of companies that are subject to intervention by a regulatory authority; subordinated securities; convertible securities; certain foreign exchange securities; derivatives such as futures, forwards, swaps, options, exotic options, swaptions, etc. (except structured notes denominated in pesos with protected initial investment); securities having terms with certain characteristics such as liquidity, risk, return, or maturity that do not comply with certain requirements set by PEMEX’s Financial Resources Committee; and securities not listed on the Mexican Stock Exchange.

The expected long-term rate of return is based on the guidelines of the Mexican Society of Consulting Actuaries, which annually issues recommendations for selecting financial assumptions based on a historical analysis conducted using economic variables such as inflation, risk-free interest rates and increases to the legal minimum wage as well as salaries in general.

As of December 31, 2009 and 2008, all of PEMEX’s plan assets were invested in Mexican Government bonds and bonds issued by financial institutions listed on the Mexican Stock Exchange. The following table shows PEMEX’s actual investment allocation at December 31 of each year.

Securities	2009		2008
Mexican Government Securities (“MGS”)	Ps.	1,090,442	Ps.	3,712,782
Bonds issued by financial institutions listed on the Mexican Stock Exchange		1,536,327		1,396,624
Mutual Funds		522,351		—
Total	Ps.	3,149,120	Ps.	5,109,406

Since the other post-retirement benefits are not based on levels of compensation, it is not necessary to use salary increase assumptions to determine expenses. The effect of a 1% increase in the healthcare cost trend rate was to increase net expense for other post-retirement benefits by Ps. 24,607,685 for 2009, Ps. 14,053,773 for 2008 and Ps. 9,686,783 for 2007, and to increase the accumulated post-retirement benefit obligation by Ps. 238,461,119 for 2009, Ps. 99,032,498 for 2008 and Ps. 14,698,361 for 2007. The effect of a 1% decrease in the healthcare cost trend rate was to decrease net expense for other post-retirement benefits by Ps. 16,036,265 for 2009, Ps. 11,706,879 for 2008 and Ps. 6,386,544 for 2007, and to decrease the accumulated post-retirement benefit obligation by Ps. 160,752,480 for 2009, Ps. 82,636,860 for 2008 and Ps. 12,007,042 for 2007.

Additional information about plan assets, including methods and assumptions used to estimate the fair values of plan assets, is as follows:

• Mexican Government Securities (MGS) include short-term Cetes, fixed rate Bonos, floating rate Bondes and inflation-linked Udibonos. Fixed rate long-term Bonos, in particular, have become the main source of funding for the Federal Treasury and have allowed the extension of the term of public debt. Each quarter, the Ministry of Finance and Public Credit announces the auction schedule for all MGS. The fair value of these investments is based on market prices obtained from local professional price providers as of the measurement date.

(Figures stated in thousands of Mexican pesos, except as noted)

• Bonds issued by financial institutions listed on the Mexican Stock Exchange are medium- and long-term debt securities that can be denominated in pesos or UDIs. The fair value of these investments is based on market prices obtained from local professional price providers as of the measurement date.

• Mutual funds, better known as “funds,” are the most accessible way for small and medium-sized investors to benefit from their savings, by investing in baskets of market securities. Investors buy shares of the funds, the performance of which is determined by the difference between the buying and selling prices of their shares. The financial resources supplied by investors are used by fund managers to buy baskets of securities and market instruments, in order to diversify risk. The fair values of these investments are based on quoted market prices for identical assets as of the measurement date.

(f) Leases

As of December 31, 2009, PEMEX did not have any significant operating lease arrangements. However, PEMEX did enter in 2008 into capital lease arrangements for a total amount of U.S. $435,235 at a fixed rate of 1.99% and an established term of 2008-2019 (see Note 10).

(g) Supplemental geographic information

Note: The above valuation and qualifying accounts are presented in accordance with U.S. GAAP. The Mexican FRS accounts titled “Reserve for sundry creditors and others” and “Reserve for employee benefits” are accrued liability accounts, not valuation and qualifying accounts, and have not been included in the table above (which includes the reserve for dismantlement and abandonment activities).

(i) Significant risks and uncertainties

Environmental

The ultimate costs to be incurred in relation to PEMEX’s environmental contingencies may exceed the total amounts reserved. Additional liabilities may be accrued as the assessment work is completed, and formal remediation plans are formulated. Numerous factors affect the reliability and precision of cleanup cost estimates, including the individual characteristics of the site, the lack of specific guidance as to permissible levels of pollution and the type of technology available for remediation, as well as general economic factors, such as inflation.

As discussed above in this Note, PEMEX accrues an environmental liability when a reasonable estimate of the costs for remediation or cleanup of the identified affected area has been made. In some cases, investigations are not yet at a stage where PEMEX is able to quantify the liability or estimate a range of possible exposure. In such cases, the amounts of PEMEX’s liabilities are indeterminate due to the unknown magnitude of possible contamination, the imprecise and potentially conflicting engineering evaluations and estimates of proper cleanup methods and costs, the unknown timing and extent of the corrective actions that may be required, and the ambiguities in Mexican environmental laws and regulations.

PEMEX is not aware of any unasserted claims or assessments that may give rise to an environmental liability, and therefore, no amounts related to such items have been reflected in the environmental accrual.

(Figures stated in thousands of Mexican pesos, except as noted)

Mexican Government

The operations and earnings of PEMEX have been, and may in the future be, affected from time to time in varying degrees by political developments and laws and regulations, such as forced divestiture of assets, budgetary adjustments, restrictions on production levels and capital expenditures, price controls, tax increases, cancellation of contract rights, refined product specifications and environmental, health and safety regulations. Both the likelihood of such occurrences and their overall effect upon PEMEX are not estimable.

Labor

PEMEX employees belonging to the Petroleum Workers’ Union (the “Union”) represent approximately 72.0% of its workforce. They have a collective bargaining agreement, which is renegotiated every two years. On July 23, 2009, Petróleos Mexicanos and the Union executed a new collective bargaining agreement that became effective on August 1, 2009. By its terms, the new collective bargaining agreement is scheduled to expire on July 31, 2011. In addition, in July 2009, Petróleos Mexicanos and the Union agreed to a 4.9% increase in wages and a 1.5% increase in other benefits under the existing collective bargaining agreement.

Product prices

Because PEMEX’s major products are energy-related commodities, significant changes in the international prices of crude oil, natural gas, refined products and petrochemical products could have a significant impact on PEMEX’s results of operations in any particular year. In 2009, crude oil represented approximately 32% of PEMEX’s sales revenues net of the IEPS Tax, and prices of the products that PEMEX produces can be influenced by changes in crude oil prices, which makes it reasonably possible that PEMEX could suffer near-term severe impacts from fluctuations in such prices.

(j) Capitalized software costs

Direct internal and external costs related to the development of internal use software are deferred and included in other assets. Capitalized software costs, net of amortization, as of December 31, 2009 and 2008, amounted to Ps. 32,755 and Ps. 140,606, respectively. Amortization expense for the years ended December 31, 2009, 2008 and 2007 amounted to Ps. 96,336, Ps. 325,529 and Ps. 112,310, respectively.

(l) Recently adopted accounting standards

Recent SEC rule revisions

Effective January 1, 2010, certain of the SEC’s rules have been revised in order to modernize the reporting requirements applicable to companies such as PEMEX in respect of oil and other hydrocarbon reserves. PEMEX adopted these rules effective December 31, 2009. See Note 23—Supplementary Information on Oil and Gas Exploration and Production Activities (Unaudited).

In addition, in January 2010, the FASB issued ASU 2010-03, Oil and Gas Reserve Estimation and Disclosures (“ASU 2010-03”) to provide consistency between the oil and gas accounting standards and the new SEC oil and gas reporting rules. ASU 2010-03 amends existing standards to align the reserves calculation and disclosure requirements under U.S. GAAP with the requirements under the SEC rules. PEMEX adopted these new standards effective December 31, 2009. The new standards are applied prospectively as a change in estimate. See Note 23—Supplementary Information on Oil and Gas Exploration and Production Activities (Unaudited).

Post-retirement benefit plan asset disclosures

In December 2008, the FASB issued GAAP that are now codified in Topic 715, which provides guidance on an employer’s disclosures about plan assets of a defined benefit pension or other post-retirement plan. Topic 715 also includes a technical amendment to the former SFAS 132(R) “Employers’ Disclosures about Pensions and other Postretirement Benefits,” effective immediately. This amendment requires non-public entities to disclose net periodic benefit cost for each annual period for which a statement of income is presented. PEMEX has disclosed net periodic benefit cost in Note 16. The disclosures about plan assets required by Topic 715 must be provided for fiscal years ending after December 15, 2009. PEMEX adopted these new standards on December 31, 2009. Adoption of Topic 715 has had no impact on PEMEX’s financial position or results of operations. See paragraph II(e) Employee benefits.

Business combinations and non-controlling interests in consolidated financial statements

In 2007, the FASB issued GAAP that are now codified in ASC Topic 805 “Business Combinations” (“Topic 805”) and ASC Topic 810 “Consolidation” (“Topic 810”), respectively. Topic 805 and Topic 810 require most identifiable assets, liabilities, non-controlling interests (previously referred to as minority interest) and goodwill acquired in a business combination to be recorded at “full fair value” and require non-controlling interests to be reported as a component of equity. This changes the accounting for transactions with non-controlling interest holders. Both Topic 805 and Topic 810 are effective for periods beginning on or after December 15, 2008 (i.e., the period beginning on January 1, 2009 for entities such as PEMEX with calendar year-ends) and earlier adoption is prohibited. Topic 805 is applied to business combinations occurring after the effective date. Topic 810 is applied prospectively to all non-controlling interests, including any that arose before the effective date. PEMEX adopted these new standards as of December 31, 2009. Non-controlling interests totaled Ps. 1,377,635 at the adoption date. See paragraph I(m) Non-controlling interest.

Fair value measurements

The FASB’s fair value measurement standard, which is now codified in ASC Topic 820 “Fair Value Measurements and Disclosures” (“Topic 820”), establishes a single authoritative definition of “fair value” based

(Figures stated in thousands of Mexican pesos, except as noted)

upon the assumptions that market participants would use when pricing an asset or liability, and creates a fair value hierarchy that prioritizes the information used to develop those assumptions. The standard requires additional disclosures, including disclosures of fair value measurements by level within the fair value hierarchy. As of December 31, 2008, PEMEX adopted the new standard as relates to its financial assets and liabilities. As of December 31, 2009, PEMEX adopted the new standard as relates to its non-financial assets and liabilities, including non-financial assets and liabilities measured at fair value in a business combination; impaired property, plant and equipment; goodwill impairment; and initial recognition of asset retirement obligations. See paragraph I(h) Accounting for derivative financial instruments and fair value measurements.

In April 2009, the FASB issued additional guidance clarifying the application of what is now Topic 820 for fair value measurements in the current economic environment, modifying the recognition of other-than-temporary impairments of debt securities, and requiring companies to disclose the fair value of financial instruments in interim periods. The revised guidance was effective for interim and annual periods ending after June 15, 2009. The guidance:

• describes how to determine the fair value of assets and liabilities in the current economic environment and reemphasizes that the objective of a fair value measurement is to reflect the price that would be received to sell an asset, or paid to transfer a liability, at the measurement date;

• modifies the requirements for recognizing other-than-temporarily impaired debt securities and significantly changes the existing impairment model for such securities;

• modifies the presentation of other-than-temporary impairment losses and increases the frequency of and expands already required disclosures about other-than-temporary impairment for debt and equity securities; and

• requires disclosure of the fair value of financial instruments in interim financial statements, the method or methods and significant assumptions used to estimate the fair value of financial instruments, and a discussion of changes, if any, in the method or methods and significant assumptions during the period.

PEMEX adopted this new guidance for the quarter ended December 31, 2009. Adoption of the new guidance had no impact on PEMEX’s financial position or results of operations.

In August 2009, the FASB issued ASU 2009-5, Measuring Liabilities at Fair Value (“ASU 2009-5”) in order to provide further guidance on how to measure the fair value of liabilities. ASU 2009-5 clarifies that, in circumstances in which a quoted price in an active market for the identical liability is not available, a reporting entity is required to measure fair value using one or more prescribed techniques. PEMEX adopted this new guidance as of December 31, 2009. Adoption of the new guidance has had no impact on PEMEX’s financial position or results of operations.

Fair value option

Under FASB guidance relating to fair value measurements now codified in ASC Topic 825 “Financial Instruments” (“Topic 825”), companies have an option to report selected financial assets and liabilities at fair value. PEMEX adopted this new guidance for optional fair value measurements as of December 31, 2008. Adoption of the new guidance has had no effect on PEMEX’s financial position or results of operations, as it has made no elections to report selected financial assets or liabilities at fair value.

(Figures stated in thousands of Mexican pesos, except as noted)

Derivative instruments and hedging activities

In March 2008, the FASB issued GAAP that are now codified in ASC Topic 815 “Derivatives and Hedging Overview” (“Topic 815”). Topic 815 requires entities that utilize derivative instruments to provide qualitative disclosures about their objectives and strategies for using such instruments, as well as any details of credit risk-related contingent features contained within derivatives. Topic 815 also requires entities to disclose additional information about the amounts and location of derivatives located within the financial statements, how the provisions of the former SFAS 133 have been applied, and the impact that hedges have on an entity’s financial position, financial performance and cash flows. Topic 815 is effective for fiscal years and interim periods beginning after November 15, 2008. PEMEX adopted this new standard as of December 31, 2009, which provides only for enhanced disclosures. Adoption of the new standard has had no impact on PEMEX’s financial position or results of operations. See paragraph I(h) Accounting for derivative financial instruments and fair value measurements.

Subsequent events

In May 2009, the FASB issued GAAP that are now codified in ASC Topic 855 “Subsequent Events” (“Topic 855”), which establishes general standards for the accounting for and disclosure of events that occur after the balance sheet date but before financial statements are issued or are available to be issued. Topic 855 sets forth (1) the period after the balance sheet date during which management of a reporting entity should evaluate events or transactions that may occur, for potential recognition or disclosure in the financial statements; (2) the circumstances under which an entity should recognize events or transactions occurring after the balance sheet date in its financial statements; and (3) the disclosures that an entity should make about events or transactions occurring after the balance sheet date. Topic 855 is effective for interim and annual reporting periods ending after June 15, 2009. PEMEX adopted this new standard as of December 31, 2009, and has evaluated subsequent events after the balance sheet date of December 31, 2009 through the time of filing these financial statements with the SEC on June 28, 2010, which is the date the financial statements were issued.

Accounting Standards Codification

As discussed above in this Note 21, in June 2009, the FASB established the Codification, which became effective on July 1, 2009, and is the source of authoritative U.S. GAAP recognized by the FASB to be applied by non-governmental entities. Rules and interpretive releases of the SEC under authority of the federal securities laws are also sources of authoritative U.S. GAAP for SEC registrants. Generally, the Codification is not expected to change U.S. GAAP. All other accounting literature excluded from the Codification will be considered non-authoritative. PEMEX adopted the Codification for the quarter ending December 31, 2009. All references to authoritative accounting literature are now referenced in accordance with the Codification.

Equity method investments

In November 2008, the FASB’s Emerging Issues Task Force (the “EITF”) reached a consensus on EITF Issue No. 08-6 “Equity Method Investment Accounting Considerations,” which is now codified in ASC Topic 323 “Investments—Equity Method and Joint Ventures” (“Topic 323”). Topic 323 continues to follow the accounting method for the initial carrying value of equity investments found in the former Accounting Principles Board (the “APB”) Opinion No. 18 “The Equity Method of Accounting for Investments in Common Stock” (“APB 18”). This method is based on a cost accumulation model and generally excludes contingent consideration. Topic 323 also specifies that other-than-temporary impairment testing should be performed by the

(Figures stated in thousands of Mexican pesos, except as noted)

investor at the investment level, and that a separate impairment assessment of the underlying assets is not required. An impairment charge by the investee should result in an adjustment of the investor’s basis of the impaired asset for the investor’s pro-rata share of such impairment. In addition, Topic 323 announces a consensus on how to account for an issuance of shares by an investee that reduces the investor’s ownership share of the investee; the investor should account for such transactions as if it had sold a proportionate share of its investment, with any gains or losses recorded in earnings. Topic 323 also addresses the accounting for a change in an investment from the equity method to the cost method after adoption of the former SFAS 160. Topic 323 affirms the existing guidance in the former APB 18, which requires cessation of the equity method of accounting and application of the former SFAS 115, or the cost method under the former APB 18, as appropriate. Topic 323 is effective for transactions occurring on or after December 15, 2008. PEMEX adopted the new guidance as of December 31, 2009. The adoption of Topic 323 has not had a material effect on PEMEX’s financial position or results of operations.

Offsetting of amounts related to certain contracts

As of January 1, 2008, PEMEX adopted guidance now codified in ASC Topic 210 “Offsetting” allowing companies to offset fair value amounts recognized for derivative instruments and the fair value amounts recognized for the right to reclaim cash collateral or the obligation to return cash collateral. The cash collateral (commonly referred to as a “margin”) must arise from derivative instruments recognized at fair value that are executed with the same counterparty under a master netting arrangement. As of December 31, 2009 and 2008, PEMEX had no cash collateral obligations.

Accounting for uncertainty in income taxes

As of January 1, 2007, PEMEX adopted new standards now codified in ASC Topic 740 “Income Taxes” (“Topic 740”), which clarified the accounting for uncertainty in income taxes recognized in a company’s financial statements. The new standards prescribed a recognition threshold and measurement attribute for the financial statement recognition and measurement of a tax position taken or expected to be taken in a tax return. They also provided guidance on derecognition, classification, interest and penalties, accounting in interim periods, disclosure, and transition. This guidance provided that a company’s tax position will be considered settled if the taxing authority has completed its examination, the company does not plan to appeal, and the possibility is remote that the taxing authority would reexamine the tax position in the future. Adoption of the new guidance had no effect on PEMEX’s financial position or results of operations.

(m) Recently issued accounting standards

In December 2009, the FASB issued ASU 2009-16, Transfers and Servicing (Topic 860): “Accounting for Transfers of Financial Assets” (“ASU 2009-16”). ASU 2009-16 removes the concept of a QSPE from Topic 860, and also eliminates the exception from applying ASC Subtopic 810-10 “Consolidation” to QSPEs, thereby requiring transferors of financial assets to evaluate whether to consolidate transferees that previously were considered QSPEs. Transferor-imposed constraints on transferees whose sole purpose is to engage in securitization or asset-backed financing activities are evaluated in the same manner under the provisions of ASU 2009-16 as transferor-imposed constraints on QSPEs were evaluated under the provisions of what is now Topic 860 prior to the effective date of ASU 2009-16 when determining whether a transfer of financial assets qualifies for sale accounting. ASU 2009-16 also clarifies the ASC Topic 860 sale accounting criteria pertaining to legal isolation and effective control, and creates more stringent conditions for reporting a transfer of a portion of a

financial asset as a sale. ASU 2009-16 is effective for a reporting entity’s annual as well as interim periods, beginning with its first annual reporting period that begins after November 15, 2009. Early adoption is not permitted. Management estimates that the initial effects of this new ASU will not be material.

In December 2009, the FASB issued ASU 2009-17, Consolidations (Topic 810): “Improvements to Financial Reporting by Enterprises Involved with Variable Interest Entities” (“ASU 2009-17”). ASU 2009-17 amends the Variable Interest Entity (“VIE”) Subsections of Subtopic 810-10 and, overall, revises the test for determining the primary beneficiary of a VIE—from a primarily quantitative calculation of risks and rewards based on the VIE’s expected losses and expected residual returns, to a primarily qualitative analysis based on identifying the party or related-party group (if any) with (a) the power to direct the activities that most significantly impact the VIE’s economic performance, and (b) the obligation to absorb losses of, or the right to receive benefits from, the VIE that could potentially be significant to such VIE. ASU 2009-17 requires that kick-out rights and participating rights be ignored in evaluating whether a variable interest holder meets the power criterion, unless those rights are unilaterally exercisable by a single party or related party group. ASU 2009-17 also revises the criteria for determining whether fees paid by an entity to a decision maker or another service provider are a variable interest in the entity, and revises the Topic 810 scope characteristic that identifies an entity as a VIE if equity-at-risk investors as a group do not have the right to control the entity through their equity interests, in order to address the impact of kick-out rights and participating rights on the analysis. Finally, ASU 2009-17 adds a new requirement to reconsider whether an entity is a VIE if the holders of the equity investment at risk, as a group, lose the power, through the rights of those interests, to direct the activities that most significantly impact the VIE’s economic performance; it further requires a company to reassess on an ongoing basis whether it is deemed to be the primary beneficiary of a VIE. ASU 2009-17 is effective for a reporting entity’s annual as well as interim periods, beginning with its first annual reporting period that begins after November 15, 2009. Early adoption is not permitted. Management estimates that the initial effects of this new ASU will not be material.

In October 2009, the FASB issued ASU 2009-13, Revenue Recognition (Topic 605): “Multiple-Deliverable Revenue Arrangements” (“ASU 2009-13”). ASU 2009-13 amends ASC Subtopic 605-25 “Multiple-Element Arrangements” to eliminate the requirement that all undelivered elements have vendor-specific objective evidence (“VSOE”) of selling price or third party evidence (“TPE”) of selling price before a reporting entity can recognize the portion of an overall arrangement fee that is attributable to items that already have been delivered. In the absence of VSOE and TPE for one or more delivered or undelivered elements in a multiple-element arrangement, entities will be required to estimate the selling prices of those elements. The overall arrangement fee will be allocated to each element (both delivered and undelivered items) based on their relative selling prices, regardless of whether those selling prices are evidenced by VSOE or TPE or are based on the entity’s estimated selling price. Application of the “residual method” of allocating an overall arrangement fee between delivered and undelivered elements will no longer be permitted upon adoption of ASU 2009-13. Additionally, the new guidance will require entities to disclose more information about their multiple-element revenue arrangements. ASU 2009-13 is effective prospectively for revenue arrangements entered into or materially modified in a reporting entity’s fiscal years beginning on or after June 15, 2010. However, early adoption is permitted. Management estimates that the initial effects of this new ASU will not be material.

In January 2010, the provisions of Topic 820 were modified to require additional disclosures, including of transfers in and out of Level 1 and 2 fair value measurements and the gross basis presentation of the reconciliation of Level 3 fair value measurements. This guidance is effective for interim and annual reporting periods beginning after December 15, 2009, except for disclosures related to Level 3 fair value measurements,

which are effective for fiscal years beginning after December 15, 2010 (including interim periods). Early adoption is permitted. PEMEX has adopted all of these provisions of Topic 820 effective December 31, 2009. Since only disclosures are affected by these requirements, the adoption of these provisions did not affect PEMEX’s financial position or results of operations.

(n) Deferred income taxes

PEMEX follows the provisions of the revised FRS D-4 for Mexican FRS purposes. Accounting for income taxes in accordance with this statement is similar to accounting for income taxes under U.S. GAAP in accordance with ASC Topic 740 “Income taxes.”

As described in Note 18, during 2005, a new fiscal regime applicable to Petróleos Mexicanos and its Subsidiary Entities was enacted. Beginning on January 1, 2006, certain Subsidiary Companies of PEMEX became subject to the tax regime applicable to all other Mexican corporations. In general, Mexican companies are taxed based on pre-tax income at a statutory rate. The statutory rate in Mexico for both 2007 and 2008 was 28%, and for 2009 was 30%. As a result of the change in fiscal regime in 2005, PEMEX began generating deferred income taxes during that year.

In July 2006, the FASB issued GAAP that PEMEX adopted on January 1, 2007, and which are now codified in Topic 740. Topic 740 clarifies the accounting for uncertain tax positions, requiring that an entity recognize in its consolidated financial statements the impact of a tax position if—based on the technical merits of that position—it is more likely than not to be sustained upon further examination. Recognized income tax positions are measured at the largest amount for which there is a greater than 50% likelihood of being realized. Changes in recognition or measurement are reflected in the period during which the change in judgment occurs. PEMEX’s accounting policy is to accrue interest and penalties related to unrecognized tax benefits only if and when required as a component of other income (expense) in the consolidated statements of operations. The adoption of Topic 740 did not have any effect on PEMEX’s consolidated financial statements.

As of January 1, 2007, and for the years ended December 31, 2009, 2008 and 2007, PEMEX did not have any unrecognized tax benefits and thus recorded no related deferred tax, Income Tax or Hydrocarbon Income Tax. In addition, PEMEX does not expect its amount of unrecognized tax benefits to change significantly within the next 12 months. The income tax returns of Petróleos Mexicanos, its Subsidiary Companies and Subsidiary Entities, for tax years 2003 and thereafter, remain subject to examination by the Mexican tax authorities.

(o) Asset retirement obligations

PEMEX’s liability provisions recognized in the balance sheet represent obligations whose settlement will likely require the future use of estimated economic resources. These provisions have been recorded based on the present value of management’s best estimate of future payments necessary to settle the liability. However, actual results could differ from the provisions recognized. No assets or trust funds have been established to satisfy these obligations.

In March 2005, the FASB issued GAAP that PEMEX adopted on December 31, 2005 and which are now codified in ASC Topic 410 “Asset Retirement and Environmental Obligations” (“Topic 410”). Topic 410 clarifies that the phrase “conditional asset retirement obligation,” as used in Topic 410, refers to a legal obligation to perform an asset retirement activity for which the timing and/or method of settlement are conditioned on a future event that may or may not be within the control of the entity. The obligation to perform the asset retirement activity is unconditional even though uncertainty exists as to the timing and/or method of settlement. Uncertainty about the timing and/or method of settlement of a conditional asset retirement obligation should be factored into the measurement of the liability when sufficient information exists. Topic 410 acknowledges that, in some cases, sufficient information may not be available to reasonably estimate the fair value of an asset retirement obligation. Topic 410 also clarifies when an entity would have sufficient information to reasonably estimate the fair value of an asset retirement obligation. The adoption of Topic 410 has not had a material impact on PEMEX’s financial position or results of operations.

The following table indicates the changes to PEMEX’s pre-tax asset retirement obligations in 2009 and 2008:

	2009		2008
Balance as of January 1	Ps.	18,775,594	Ps.	17,148,390

(p) Reclassifications

PEMEX’s condensed consolidated financial statements for the year ended December 31, 2007 have been reclassified in certain accounts with the purpose of making them comparable with the consolidated financial statements for the years ended December 31, 2008 and December 31, 2009.

NOTE 22—SUBSIDIARY GUARANTOR INFORMATION, PIDIREGAS LIABILITIES

AND THE PEMEX PROJECT FUNDING MASTER TRUST (THE MASTER TRUST):

The following consolidating information presents condensed consolidating balance sheets at December 31, 2009 and 2008 and condensed consolidating statements of operations and cash flows for the years ended December 31, 2009, 2008 and 2007 of Petróleos Mexicanos, the Master Trust, Pemex-Exploration and Production, Pemex-Refining, Pemex-Gas and Basic Petrochemicals and the Non-Guarantor Subsidiaries (as defined below; excluding the Master Trust).

These statements are prepared in conformity with Mexican FRS, and until December 31, 2007, include the recognition of inflation in accordance with FRS B-10, with one exception: for the purposes of the presentation of the subsidiary guarantor information, the Subsidiary Entities and Subsidiary Companies have been accounted for as investments under the equity method by Petróleos Mexicanos. Earnings of subsidiaries are therefore reflected in Petróleos Mexicanos’ investment account and earnings. The principal elimination entries eliminate Petróleos Mexicanos’ investment in subsidiaries and inter-company balances and transactions. Pemex-Exploration and Production, Pemex-Refining and Pemex-Gas and Basic Petrochemicals (collectively, the “Subsidiary

Guarantors”) and Pemex-Petrochemicals are 100%-owned subsidiaries of Petróleos Mexicanos. Pemex-Petrochemicals, Pemex Finance and the Subsidiary Companies collectively comprise the non-guarantor subsidiaries (the “Non-Guarantor Subsidiaries”). Petróleos Mexicanos’ guaranty of the indebtedness of the Master Trust is full and unconditional. The guaranties by the Subsidiary Guarantors of Petróleos Mexicanos’ guaranty of the Master Trust’s payment obligations are full and unconditional and joint and several.

The Master Trust, a consolidated entity that is a Delaware statutory trust, was organized under the laws of Delaware on November 10, 1998. On December 31, 1998, PEMEX transferred all assets and liabilities related to PIDIREGAS for an amount equaling Ps. 12,471,156 (in nominal terms) to the Master Trust. The main objective of the Master Trust was, until December 31, 2008, to administer financial resources related to PIDIREGAS, such financial resources being designated by PEMEX for that purpose, by assuming payment obligations under contracts relating to PIDIREGAS and acting as the borrower under financing arrangements for PIDIREGAS.

Under an Assignment and Indemnity Agreement dated November 10, 1998, among Petróleos Mexicanos, the Master Trust and the Subsidiary Guarantors, Petróleos Mexicanos and the Subsidiary Guarantors have certain obligations to the Master Trust with respect to the liabilities incurred by the Master Trust in connection with PIDIREGAS. These obligations include:

(i) the obligation of Petróleos Mexicanos to guarantee the repayment of the debt obligations undertaken by the Master Trust to finance PIDIREGAS;

(ii) the obligation of Petróleos Mexicanos and of the Subsidiary Guarantor which is sponsoring the relevant PIDIREGAS to make such payments to the Master Trust as may be necessary for the Master Trust to fulfill its payment obligations in respect of any financings that the Master Trust has entered into in connection with such project; and

(iii) the joint and several obligation of Petróleos Mexicanos and each of the aforementioned Subsidiary Guarantors to indemnify the Master Trust with respect to any liability incurred by the Master Trust in connection with PIDIREGAS.

As discussed in Note 3(g), as a result of the amendments to the Federal Law of Budget and Fiscal Accountability, the Master Trust will no longer participate in PIDIREGAS financings and Petróleos Mexicanos has assumed, as primary obligor, all payment obligations under PIDIREGAS financings entered into by the Master Trust. Petróleos Mexicanos completed its assumption of the Master Trust’s payment obligations under its financings during the second half of 2009.

The Master Trust is consolidated in the financial statements of PEMEX for each of the periods presented in accordance with consolidation principles detailed in FRS B-8 “Consolidated and Combined Financial Statements.” In accordance with U.S. GAAP, the Master Trust is a special purpose entity requiring consolidation in the financial statements, as it does not meet non-consolidation criteria as specified in U.S. accounting literature.

The significant differences between Mexican FRS and U.S. GAAP, as they affect PEMEX, are described in Note 21. The following also presents the reconciliation of equity to U.S. GAAP as of December 31, 2009 and 2008, and the reconciliation of income to U.S. GAAP for each of the three years ended December 31, 2009, 2008 and 2007, for each of Petróleos Mexicanos, the Master Trust, the Subsidiary Guarantors and the Non-Guarantor Subsidiaries. For the year ended December 31, 2007, the following reconciliation to U.S. GAAP does not include the reversal of Mexican FRS inflation accounting adjustments. There were no Mexican FRS inflation accounting adjustments made for any other year.

Petróleos Mexicanos is the only PEMEX entity that is authorized to contract debt and has debt outstanding as of the date of this report, and all guaranteed debt is issued by Petróleos Mexicanos. The guarantees of the Subsidiary Guarantors are full and unconditional and joint and several. PEMEX’s management has not presented separate financial statements for the Subsidiary Guarantors, because it has determined that such information is not material to investors.

(Figures stated in thousands of Mexican pesos, except as noted)

NOTE 23—SUPPLEMENTARY INFORMATION ON OIL AND GAS EXPLORATION AND

PRODUCTION ACTIVITIES (UNAUDITED):

Effective January 1, 2010, certain of the SEC’s rules have been revised in order to modernize the reporting requirements applicable to companies such as PEMEX in respect of oil and other hydrocarbon reserves. The most significant of these revisions include the following:

• Crude oil prices. Evaluation of the economic producibility of reserves and discounted cash flows must each now be based on a 12-month average crude oil price that is calculated by using the price on the first day of each month during the period, unless contractual arrangements designate a different price to be used.

• Proved undeveloped reserves. Reserves may now be classified as proved undeveloped reserves if: (1) there is a high degree of confidence that the relevant quantities of such reserves will be recovered; and (2) the related drilling is scheduled to begin within the next five years, unless the specific circumstances justify a longer time.

• Reserves estimation using new technologies. Reserves may now be estimated through the use of reliable advanced technologies in addition to those, such as flow tests and production history, previously recognized by the SEC.

• Reserves estimation personnel and process. Additional disclosure is now required regarding the qualifications of those who oversee a company’s reserves estimation process. A general discussion is also now required of the internal controls used to assure the objectivity of reserves estimates.

• Non-Traditional Resources. The definition of “oil and gas producing activities” has been expanded, and now focuses on the marketable product, rather than on the method of extraction.

There has been no material change in Mexico’s proved reserves as a result of the application of these revised SEC rules.

During 2009, PEMEX did not record any material increase in Mexico’s hydrocarbons reserves as a result of the use of new technologies.

In order to ensure the reliability of its reserves estimation efforts, since 1996 PEMEX has undertaken the internal certification of its estimates of Mexico’s reserves as follows. Initially, teams of geoscientists from Pemex-Exploration and Production’s exploration and exploitation business units (each of these units consisting of a series of projects) prepare the reserves estimates, using distinct estimation processes for valuations relating to new discoveries and developed fields, respectively. Subsequently, the regional reserves offices collect these reserves estimates from the units and request from the Gerencia de Reservas de Hidrocarburos y Proyectos de Explotación (the Hydrocarbons Reserves and Exploitation Projects Management Office), the central hydrocarbon reserves management body of Pemex-Exploration and Production, the review and certification of such valuations and the booking of the related reserves. This internal certification process is undertaken in accordance with internal guidelines for estimating and classifying proved reserves that are based on the SEC’s rules and definitions. The Hydrocarbons Reserves and Exploitation Projects Management Office, which additionally oversees and conducts an internal audit of the above process, consists entirely of professionals with geological, geophysical, petrophysical and reservoir engineering backgrounds. The engineers who participate in PEMEX’s reserves estimation process are experienced in: reservoir numerical simulation; wells drilling and completion; Pressure, Volume and Temperature (“PVT”) analysis; NODAL^TM (an analytical tool used in forecasting the

Furthermore, all of these personnel have been previously certified by the Mexican Ministry of Education, most have earned master’s degrees in areas of study such as Petroleum Engineering, Geology and Geophysical Engineering, and they possess an average of over ten years of professional experience.

In addition to the above internal review process, Pemex-Exploration and Production’s final reserves estimates are audited by independent engineering firms. Three independent engineering firms audited Pemex-Exploration and Production’s estimates of Mexico’s proved reserves as of December 31, 2009: Netherland, Sewell International, S. de R.L. de C.V. (“Netherland Sewell”); DeGolyer and MacNaughton (“D&M”); and Ryder Scott Company, L.P. (“Ryder Scott,” and, together with Netherland Sewell and D&M, the “Independent Engineering Firms”). The reserves estimates reviewed by the Independent Engineering Firms totaled 99.4% of Mexico’s reserves. The remaining 0.6% of reserves consisted of (a) reserves that are in the process of review but have not yet been certified, and (b) reserves located in certain areas in which third parties provide drilling services to Pemex-Exploration and Production. Netherland Sewell reviewed the reserves in the Northeastern Marine region and Southern region, D&M reviewed the reserves in the Southwestern Marine region, and Ryder Scott reviewed the reserves in the Northern region. In addition, Ryder Scott reviewed a portion of Mexico’s reserves located in areas in which third parties provide services to Pemex-Exploration and Production through the FPWC program. Under such agreements, the corresponding third party is responsible for assessing the volume of reserves, which is in turn certified by an engineering firm hired by such party. The audits conducted by the Independent Engineering Firms consisted primarily of: (1) analysis of historical static and dynamic reservoir data provided by Pemex-Exploration and Production; (2) construction or updating of the Independent Engineering Firms’ own static and dynamic reservoir characterization models of Mexican oil fields; (3) economic analysis of selected fields; and (4) review of Pemex-Exploration and Production’s production forecasts and reserves estimates.

Since reserves estimates are, by definition, only estimates, they cannot be reviewed for the purpose of verifying exactness. Instead, the Independent Engineering Firms conducted a detailed review of Pemex-Exploration and Production’s reserves estimates so that they could express an opinion as to whether, in the aggregate, the reserves estimates that Pemex-Exploration and Production furnished were reasonable and had been estimated and presented in conformity with generally accepted petroleum engineering and evaluation principles.

All questions that arose during the Independent Engineering Firms’ review process were resolved by Pemex-Exploration and Production to the satisfaction of the Independent Engineering Firms. The Independent Engineering Firms have concluded that the estimated total proved oil and natural gas reserve volumes set forth in this report are, in the aggregate, reasonable and have been prepared in accordance with Rule 4-10(a) of Regulation S-X of the SEC, as amended, are consistent with international reserves reporting practice, and are in accordance with the oil and gas reserves disclosure provisions of Topic 932.

The following tables provide supplementary information on the oil and gas exploration, development and production activities of Pemex-Exploration and Production in compliance with Topic 932 and ASU 2010-03.

All exploration and production activities of Pemex-Exploration and Production are conducted in Mexico.

The supplemental data presented herein reflect information for all of Pemex-Exploration and Production’s oil and gas producing activities. Capitalized costs and results of operations presented herein have been prepared in accordance with U.S. GAAP.

Under the Mexican Constitution and the Regulatory Law, all oil and other hydrocarbon reserves within Mexico are owned by the Mexican nation and not by PEMEX. Under the Petróleos Mexicanos Law, Petróleos Mexicanos and the Subsidiary Entities other than Pemex-Petrochemicals do not own these reserves but have the exclusive rights to extract them and to market the resulting products. The exploration and development activities of Petróleos Mexicanos and the Subsidiary Entities are limited to those reserves that are located in Mexico. As discussed in Note 18, a new fiscal regime, the Federal Duties Law, became applicable to PEMEX, effective on January 1, 2006, and was subsequently modified in October 2007, November 2008 and November 2009.

Taxes for 2009 were calculated pursuant to the Federal Duties Law effective as amended on November 13, 2008, which is described in Note 18. For 2010 and future years, the Federal Duties Law includes the following duties:

• Ordinary Hydrocarbons Duty—A variable rate of 73.0% in 2010, 72.5% in 2011 and 71.5% in 2012-2034 is applied as a function of the crude oil and gas prices as of December 31. The base for calculating this duty is the value of total crude oil and natural gas production during the year minus certain allowed deductions (depreciation, costs, expenses and applicable duties). The deductions allowed may not exceed the value obtained by multiplying the produced volume for a particular year times the price of U.S. $6.50 per barrel of oil equivalent for crude oil and associated natural gas, and U.S. $2.70 per thousand cubic feet of non-associated natural gas, respectively.

• Hydrocarbons Duty for the Stabilization Fund—A rate between 1% and 10% is applied to the value of crude oil production when the weighted average price of the crude oil for export for a year exceeds U.S. $22.00 to U.S. $31.00 per barrel.

• Duty for Scientific and Technological Research on Energy—A rate of 0.65% in 2010-2034 is applied to the value of crude oil and natural gas production during the year.

• Duty for Oil Monitoring—A rate of 0.003% is applied to the value of total crude oil and natural gas production during the year.

• Extraordinary Duty on Crude Oil Exports—A rate of 13.1% is applied to the value resulting from the multiplication of (i) the difference between the annual weighted average Mexican crude oil export price and the budgeted crude oil price times; and (ii) the annual export volume. The budgeted crude oil price

for 2009 was U.S. $70.00 per barrel and for 2010 is U.S. $59.00 per barrel. This duty is credited against the Hydrocarbons Duty for the Stabilization Fund. The income from this duty is directed to the states of Mexico via the Income of the Federative Entities Stabilization Fund.

• Extraction of Hydrocarbons Duty—From 2010-2034, a rate of 15% is applied to the value of extracted production of crude oil and natural gas for the year from the fields located in the Paleocanal de Chicontepec and the deep waters in the Gulf of Mexico.

• Special Hydrocarbons Duty—A rate ranging from 30% to 36% is applied to the value of extracted production of crude oil and natural gas for the year from the fields located in the Paleocanal de Chicontepec and the deep waters in the Gulf of Mexico, minus certain permitted deductions (including specific investments, certain expenses and costs, among others, subject to certain conditions), which may not exceed the cost limit established in article 257 of the Federal Duties Law.

Proved oil and natural gas reserves are those estimated quantities of crude oil, natural gas and natural gas liquids which geological and engineering data demonstrate with reasonable certainty to be economically producible—from a given date forward, from known reservoirs, and under existing economic conditions, operating methods and government regulations. Mexico’s proved reserves are estimated by Pemex-Exploration and Production’s technical staff, using the year-end crude oil and natural gas prices to calculate its reserves estimates, and reviewed by a central group within Pemex-Exploration and Production to ensure consistency.

Pemex-Exploration and Production estimates Mexico’s reserves using standard geological and engineering methods generally accepted by the petroleum industry. The choice of method or combinations of methods employed in the analysis of each reservoir is determined by: experience in the area; stage of development; quality and completeness of basic data; and production and pressure histories.

Reserves data set forth herein represent only estimates. Reserves valuation is a subjective process of estimating underground accumulations of crude oil and natural gas that cannot be measured in an exact manner. The accuracy of any reserves estimate depends on the quality of available data, engineering and geological interpretation and professional judgment. As a result, estimates from different engineers may vary. In addition, the results of drilling, testing and producing subsequent to the date of an estimate may lead to its revision.

Mexico’s total proved developed and undeveloped reserves of crude oil, condensates and liquefiable hydrocarbons recoverable from processing plants decreased by 1.5% in 2009, from 11,865 million barrels of oil equivalent as of December 31, 2008 to 11,691 million barrels of oil equivalent as of December 31, 2009.

Mexico’s proved developed reserves of crude oil, condensates and liquefiable hydrocarbons recoverable from processing plants decreased by 5.2% in 2009, from 8,618 million barrels of oil equivalent as of December 31, 2008 to 8,167 million barrels of oil equivalent as of December 31, 2009.

Mexico’s total proved developed and undeveloped dry gas reserves decreased by 5.8% in 2009, from 12,702 billion cubic feet at December 31, 2008 to 11,966 billion cubic feet at December 31, 2009. Mexico’s proved developed dry gas reserves decreased by 7.6% in 2009, from 8,206 billion cubic feet at December 31, 2008 to 7,586 billion cubic feet at December 31, 2009.

Based on reservoir performance, new information, and discoveries and production during 2009, proved reserves of crude oil, natural gas, condensates and liquefiable hydrocarbons for all regions as of December 31, 2009 were estimated to be 13,992.1 million barrels of oil equivalent, as compared to 14,307.7 million barrels of oil equivalent as of December 31, 2008.

C. Standardized measure of discounted future net cash flows related to proved oil and gas reserves (unaudited)

The standardized measure tables presented below relate to proved oil and gas reserves excluding proved reserves scheduled to be produced after the year 2034. This measure is presented in accordance with Topic 932.

Estimated future cash inflows from production are computed by applying average prices of oil and gas, as measured on the first day of the month during each of the 12 months of 2009. Future development and production costs are those estimated future expenditures needed to develop and produce the year-end estimated proved reserves after a net cash flows discount factor of 10%, assuming constant year-end economic conditions.

Future tax expenses are computed by applying the appropriate year-end statutory tax rates with consideration of the tax rates of the new fiscal regime for Pemex-Exploration and Production already approved for 2010 to the future pre-tax net cash flows related to Mexico’s proved oil and gas reserves.

The estimated future payment of taxes was calculated based on the new fiscal regime made applicable to Pemex-Exploration and Production by decree, effective January 1, 2010, and which reformed Chapter XII of the Federal Law of Hydrocarbon Duties.

The standardized measure provided below represents a comparative benchmark value rather than an estimate of expected future cash flows or fair market value of PEMEX’s production rights. There are numerous uncertainties inherent in estimating quantities of proved reserves and in projecting future rates of production and timing of development expenditures, including many factors beyond the control of the producer. Accordingly, reserves estimates may be materially different from the quantities of crude oil and natural gas that are ultimately recovered.

México 11311, D.F.

Dear Ing. Morales:

At the request of Pemex Exploración y Producción (Pemex), Ryder Scott Company (Ryder Scott) has conducted a reserves audit of the estimates of the proved reserves as prepared by Pemex’s engineering and geological staff based on the definitions and disclosure guidelines contained in the United States Securities and Exchange Commission Title 17, Code of Federal Regulations, Modernization of Oil and Gas Reporting, Final Rule released January 14, 2009 in the Federal Register (SEC regulations).

The reserves audit conducted by Ryder Scott was completed on March 24, 2010. This third party letter report presents the results of our reserves audit based on the guidelines set forth under Section 229.1202(a)(7) and (8) of the SEC regulations.

The properties reviewed by Ryder Scott incorporate Pemex reserve determinations comprised of the Northern Region and are located in the states of Coahuila, Nuevo Leon, Puebla, San Luis Potosi, Tamaulipas and Veracruz. Certain properties are located in territorial waters, offshore Gulf of Mexico. Pemex owns interests in other Regions located in Mexico that were not evaluated by Ryder Scott. The proved net reserves attributable to the properties that we reviewed account for 94.2 percent of the total proved net oil equivalent barrels (BOE) for the Northern Region.

As prescribed by the Society of Petroleum Engineers in Paragraph 2.2(f) of the Standards Pertaining to the Estimating and Auditing of Oil and Gas Reserves Information (SPE auditing standards), a reserves audit is defined as “the process of reviewing certain of the pertinent facts interpreted and assumptions made that have resulted in an estimate of reserves prepared by others and the rendering of an opinion about (1) the appropriateness of the methodologies employed; (2) the adequacy and quality of the data relied upon; (3) the depth and thoroughness of the reserves estimation process; (4) the classification of reserves appropriate to the relevant definitions used; and (5) the reasonableness of the estimated reserve quantities.”

Based on our review, including the data, technical processes and interpretations presented by Pemex, it is our opinion that the overall procedures and methodologies utilized by Pemex in determining the proved reserves comply with the current SEC regulations and that the overall proved reserves for the reviewed properties as estimated by Pemex are, in the aggregate, reasonable and within the established audit tolerance guidelines set forth in the SPE auditing standards.

The estimated reserves presented in this report are related to hydrocarbon prices. Pemex has informed us that in the preparation of their reserve and income projections, as of December 31, 2009, they used average prices during the 12-month period prior to the ending date of the period covered in this report, determined as unweighted arithmetic averages of the prices in effect on the first-day-of-the-month for each month within such period, unless prices were defined by contractual arrangements as required by the SEC regulations. Actual future prices may vary significantly from the prices required by SEC regulations; therefore, volumes of reserves actually recovered may differ significantly from the estimated quantities presented in this report. The net reserves as estimated by Pemex attributable to Pemex’s interest in properties that we reviewed and the reserves of properties that we did not review are summarized as follows:

Reserves Included in This Report

In our opinion, the proved reserves presented in this report comply with the definitions, guidelines and disclosure requirements as required by the SEC regulations.

Proved oil and gas reserves are those quantities of oil and gas, which, by analysis of geoscience and engineering data, can be estimated with reasonable certainty to be economically producible from a given date forward. Moreover, estimates of reserves may increase or decrease as a result of future operations, effects of regulation by governmental agencies or geopolitical risks. As a result, the estimates of oil and gas reserves have an intrinsic uncertainty. The reserves included in this report are therefore estimates only and should not be construed as being exact quantities. They may or may not be actually recovered.

An abridged version of the SEC reserves definitions from 210.4-10(a) entitled “Petroleum Reserves Definitions” is included as an attachment to this report.

Audit Data, Methodology, Procedure and Assumptions

The reserves for the properties that we reviewed were estimated by performance methods or the volumetric method. In general, reserves attributable to producing wells and/or reservoirs were estimated by performance methods such as decline curve analysis, material balance and/or reservoir simulation which utilized extrapolations of historical production and pressure data available through December 31, 2009 in those cases where such data were considered to be definitive. In certain cases, producing reserves were estimated by the volumetric method where there were inadequate historical performance data to establish a definitive trend and where the use of production performance data as a basis for the reserve estimates was considered to be inappropriate. Reserves attributable to non-producing and undeveloped reserves included herein were estimated by the volumetric method or the analogy method, which utilized all pertinent well and seismic data available through December 31, 2009.

To estimate economically recoverable oil and gas reserves, we consider many factors and assumptions including, but not limited to, the use of reservoir parameters derived from geological, geophysical and engineering data which cannot be measured directly, economic criteria based on current costs and SEC pricing requirements, and forecasts of future production rates. Under the SEC regulations 210.4-10(a)(22)(v) and (26), proved reserves must be demonstrated to be economically producible based on existing economic conditions including the prices and costs at which economic producibility from a reservoir is to be determined as of the effective date of the report. Pemex has informed us that they have furnished us all of the accounts, records, geological and engineering data, and reports and other data required for this investigation. In performing our audit of Pemex’s forecast of future production and income, we have relied upon data furnished by Pemex with respect to property interests owned, production and well tests from examined wells, normal direct costs of operating the properties, other costs such as transportation and/or processing fees, recompletion and development costs, product prices based on the SEC regulations, geological structural and isochore maps, well logs, core analyses, and pressure measurements. Ryder Scott reviewed such factual data for its reasonableness; however, we have not conducted an independent verification of the data supplied by Pemex.

As previously stated, the hydrocarbon prices used by Pemex are based on SEC price parameters using the average prices during the 12-month period prior to the ending date of the period covered in this report, determined as the unweighted arithmetic averages of the prices in effect on the first-day-of-the-month for each month within such period, unless prices were defined by contractual

RYDER SCOTT COMPANY    PETROLEUM CONSULTANTS

Pemex Exploración y Producción

arrangements. For hydrocarbon products sold under contract, the contract prices, including fixed and determinable escalations exclusive of inflation adjustments, were used until expiration of the contract. Upon contract expiration, the prices were adjusted to the 12-month unweighted arithmetic average as previously described. Product prices which were actually used for each property reflect adjustment for gravity, quality, local conditions, and/or distance from market.

The effects of derivative instruments designated as price hedges of oil and gas quantities are not reflected in Pemex’s individual property evaluations.

While it may reasonably be anticipated that the future prices received for the sale of production and the operating costs and other costs relating to such production may also increase or decrease from existing levels, such changes were, in accordance with rules adopted by the SEC, omitted from consideration in making this evaluation.

Gas imbalances, if any, were not taken into account in the gas reserve estimates reviewed. The gas volumes included herein do not attribute gas consumed in operations as reserves.

Operating costs used by Pemex are based on the operating expense reports of Pemex and include only those costs directly applicable to the properties. The operating costs include a portion of general and administrative costs allocated directly to the properties. As we were informed by Pemex, the operating costs for operated properties include an appropriate level of corporate general administrative and overhead costs. The operating costs and capital costs for non-operated properties include certain costs pertaining to operating agreements as executed between Pemex and the operating companies. No deduction was made for loan repayments, interest expenses, or exploration and development prepayments that were not charged directly to the properties.

Development costs used by Pemex are based on authorizations for expenditure for the proposed work or actual costs for similar projects.

Because of the direct relationship between volumes of proved undeveloped reserves and development plans, we include in the proved undeveloped category only reserves assigned to undeveloped locations that we have been assured will definitely be drilled. Pemex has assured us of their intent and ability to proceed with the development activities included in this report, and that they are not aware of any legal, regulatory or political obstacles that would significantly alter their plans.

Current costs used by Pemex were held constant throughout the life of the properties.

Pemex’s forecasts of future production rates are based on historical performance from wells now on production or estimated initial production rates based on test data and other related information for those wells or locations that are not currently producing. Forecasts of future production rates may be more or less than estimated because of changes in the timing of future development plans. Wells or locations that are not currently producing may start producing earlier or later than anticipated in the forecasts prepared by Pemex for the Northern Region.

Ryder Scott did not evaluate country and geopolitical risks in the country of Mexico. Pemex’s operations may be subject to various levels of governmental controls and regulations. These controls and regulations may include matters relating to land tenure, drilling, production practices, environmental protection, marketing and pricing policies, royalties, various taxes and levies including income tax and are subject to change from time to time. Such changes in governmental regulations and policies may cause volumes of reserves actually recovered to differ significantly from the estimated quantities.

The estimates of reserves presented herein were based upon a detailed study of the properties in which Pemex owns an interest; however, we have not made any field examination of the properties. No consideration was given in this report to potential environmental liabilities that may exist nor were any costs included for potential liability to restore and clean up damages, if any, caused by past operating practices.

Certain technical personnel of Pemex are responsible for the preparation of reserve estimates on new properties and for the preparation of revised estimates, when necessary, on old properties. These personnel assembled the necessary data and maintained the data and workpapers in an orderly manner. We consulted with these technical personnel and had access to their workpapers and supporting data in the course of our audit.

The data described herein were accepted as authentic and sufficient for determining the reserves unless, during the course of our examination, a matter of question came to our attention in which case the data were not accepted until all questions were satisfactorily resolved. Our audit included such tests and procedures as we considered necessary under the circumstances to render the conclusions set forth herein.

Audit Opinion

In our opinion, Pemex’s estimates of future reserves for the reviewed properties were prepared in accordance with generally accepted petroleum engineering and evaluation principles for the estimation of future reserves as set forth in the Society of Petroleum Engineers’ Standards Pertaining to the Estimating and Auditing of Oil and Gas Reserves Information, and we found no bias in the utilization and analysis of data in estimates for these properties.

The overall proved reserves for the reviewed properties as estimated by Pemex are, in the aggregate, reasonable and within the established audit tolerance guidelines of 10 percent as set forth in the Standards Pertaining to the Estimating and Auditing of Oil and Gas Reserves Information promulgated by the Society of Petroleum Engineers.

In general, we were in reasonable agreement with Pemex’s estimates of proved reserves for the properties which we reviewed; however, in certain cases there was more than an acceptable variance between Pemex’s estimates and our estimates due to a difference in interpretation of data or due to our having access to data which were not available to Pemex when its reserve estimates were prepared. In these cases, Pemex revised its estimates to conform to our estimates. As a consequence, it is our opinion that the data presented herein for the properties that we reviewed fairly reflect the estimated net reserves owned by Pemex.

Other Properties

Other properties, as used herein, are those properties of Pemex which we did not review. The proved net reserves attributable to the other properties account for 5.8 percent of the total proved net equivalent barrels of reserves based on estimates prepared by Pemex as of December 31, 2009.

The same technical personnel of Pemex were responsible for the preparation of the reserve estimates for the properties that we reviewed as well as for the properties not reviewed by Ryder Scott.

As Adapted From:

RULE 4-10(a) of REGULATION S-X PART 210

UNITED STATES SECURITIES AND EXCHANGE COMMISSION (SEC)

PREAMBLE

On January 14, 2009, the United States Securities and Exchange Commission (SEC) published the “Modernization of Oil and Gas Reporting; Final Rule” in the Federal Register of National Archives and Records Administration (NARA). The “Modernization of Oil and Gas Reporting; Final Rule” includes revisions and additions to the definition section in Rule 4-10 of Regulation S-X, revisions and additions to the oil and gas reporting requirements in Regulation S-K, and amends and codifies Industry Guide 2 in Regulation S-K. The “Modernization of Oil and Gas Reporting; Final Rule”, including all references to Regulation S-X and Regulation S-K, shall be referred to herein collectively as the “SEC Regulations”. The SEC Regulations take effect for all filings made with the United States Securities and Exchange Commission as of December 31, 2009, or after January 1, 2010. Reference should be made to the full text under Title 17, Code of Federal Regulations, Regulation S-X Part 210, Rule 4-10(a) for the complete definitions, as the following definitions, descriptions and explanations rely wholly or in part on excerpts from the original document (direct passages excerpted from the aforementioned SEC document are denoted in italics herein).

Reserves are those estimated remaining quantities of petroleum which are anticipated to be economically producible, as of a given date, from known accumulations under defined conditions. All reserve estimates involve some degree of uncertainty. The uncertainty depends chiefly on the amount of reliable geologic and engineering data available at the time of the estimate and the interpretation of these data. The relative degree of uncertainty may be conveyed by placing reserves into one of two principal classifications, either proved or unproved. Unproved reserves are less certain to be recovered than proved reserves and may be further sub-classified as probable and possible reserves to denote progressively increasing uncertainty in their recoverability. Under the SEC Regulations as of December 31, 2009, or after January 1, 2010, a company may optionally disclose estimated quantities of probable or possible oil and gas reserves in documents publicly filed with the Commission. The SEC Regulations continue to prohibit disclosure of estimates of oil and gas resources other than reserves and any estimated values of such resources in any document publicly filed with the Commission unless such information is required to be disclosed in the document by foreign or state law as noted in §229.1202 Instruction to Item 1202.

Reserves estimates will generally be revised as additional geologic or engineering data become available or as economic conditions change.

Reserves may be attributed to either natural energy or improved recovery methods. Improved recovery methods include all methods for supplementing natural energy or altering natural forces in the reservoir to increase ultimate recovery. Examples of such methods are pressure maintenance, natural gas cycling, waterflooding, thermal methods, chemical flooding, and the use of miscible and immiscible displacement fluids. Other improved recovery methods may be developed in the future as petroleum technology continues to evolve.

RYDER SCOTT COMPANY    PETROLEUM CONSULTANTS

PETROLEUM RESERVES DEFINITIONS

Page 2

Reserves may be attributed to either conventional or unconventional petroleum accumulations. Petroleum accumulations are considered as either conventional or unconventional based on the nature of their in-place characteristics, extraction method applied, or degree of processing prior to sale. Examples of unconventional petroleum accumulations include coalbed or coalseam methane (CBM/CSM), basin-centered gas, shale gas, gas hydrates, natural bitumen and oil shale deposits. These unconventional accumulations may require specialized extraction technology and/or significant processing prior to sale.

Reserves do not include quantities of petroleum being held in inventory.

Because of the differences in uncertainty, caution should be exercised when aggregating quantities of petroleum from different reserves categories.

RESERVES (SEC DEFINITIONS)

Securities and Exchange Commission Regulation S-X §210.4-10(a)(26) defines reserves as follows:

Reserves. Reserves are estimated remaining quantities of oil and gas and related substances anticipated to be economically producible, as of a given date, by application of development projects to known accumulations. In addition, there must exist, or there must be a reasonable expectation that there will exist, the legal right to produce or a revenue interest in the production, installed means of delivering oil and gas or related substances to market, and all permits and financing required to implement the project.

Note to paragraph (a)(26): Reserves should not be assigned to adjacent reservoirs isolated by major, potentially sealing, faults until those reservoirs are penetrated and evaluated as economically producible. Reserves should not be assigned to areas that are clearly separated from a known accumulation by a non-productive reservoir (i.e., absence of reservoir, structurally low reservoir, or negative test results). Such areas may contain prospective resources (i.e., potentially recoverable resources from undiscovered accumulations).

PROVED RESERVES (SEC DEFINITIONS)

Securities and Exchange Commission Regulation S-X §210.4-10(a)(22) defines proved oil and gas reserves as follows:

Proved oil and gas reserves. Proved oil and gas reserves are those quantities of oil and gas, which, by analysis of geoscience and engineering data, can be estimated with reasonable certainty to be economically producible—from a given date forward, from known reservoirs, and under existing economic conditions, operating methods, and government regulations—prior to the time at which contracts providing the right to operate expire, unless evidence indicates that renewal is reasonably certain, regardless of whether deterministic or probabilistic methods are used for the estimation. The project to extract the hydrocarbons must have commenced or the operator must be reasonably certain that it will commence the project within a reasonable time.

(i) The area of the reservoir considered as proved includes:

(A) The area identified by drilling and limited by fluid contacts, if any, and

RYDER SCOTT COMPANY    PETROLEUM CONSULTANTS

PETROLEUM RESERVES DEFINITIONS

Page 3

(B) Adjacent undrilled portions of the reservoir that can, with reasonable certainty, be judged to be continuous with it and to contain economically producible oil or gas on the basis of available geoscience and engineering data.

(ii) In the absence of data on fluid contacts, proved quantities in a reservoir are limited by the lowest known hydrocarbons (LKH) as seen in a well penetration unless geoscience, engineering, or performance data and reliable technology establishes a lower contact with reasonable certainty.

PROVED RESERVES (SEC DEFINITIONS) CONTINUED

(iii) Where direct observation from well penetrations has defined a highest known oil (HKO) elevation and the potential exists for an associated gas cap, proved oil reserves may be assigned in the structurally higher portions of the reservoir only if geoscience, engineering, or performance data and reliable technology establish the higher contact with reasonable certainty.

(iv) Reserves which can be produced economically through application of improved recovery techniques (including, but not limited to, fluid injection) are included in the proved classification when:

(A) Successful testing by a pilot project in an area of the reservoir with properties no more favorable than in the reservoir as a whole, the operation of an installed program in the reservoir or an analogous reservoir, or other evidence using reliable technology establishes the reasonable certainty of the engineering analysis on which the project or program was based; and

(B) The project has been approved for development by all necessary parties and entities, including governmental entities.

(v) Existing economic conditions include prices and costs at which economic producibility from a reservoir is to be determined. The price shall be the average price during the 12-month period prior to the ending date of the period covered by the report, determined as an unweighted arithmetic average of the first-day-of-the-month price for each month within such period, unless prices are defined by contractual arrangements, excluding escalations based upon future conditions.

Reserves status categories define the development and producing status of wells and reservoirs. Reference should be made to Title 17, Code of Federal Regulations, Regulation S-X Part 210, Rule 4-10(a) and the SPE-PRMS as the following reserves status definitions are based on excerpts from the original documents (direct passages excerpted from the aforementioned SEC and SPE-PRMS documents are denoted in italics herein).

DEVELOPED RESERVES (SEC DEFINITIONS)

Securities and Exchange Commission Regulation S-X §210.4-10(a)(6) defines developed oil and gas reserves as follows:

Developed oil and gas reserves are reserves of any category that can be expected to be recovered:

(i) Through existing wells with existing equipment and operating methods or in which the cost of the required equipment is relatively minor compared to the cost of a new well; and

(ii) Through installed extraction equipment and infrastructure operational at the time of the reserves estimate if the extraction is by means not involving a well.

Developed Producing (SPE-PRMS Definitions)

While not a requirement for disclosure under the SEC regulations, developed oil and gas reserves may be further sub-classified according to the guidance contained in the SPE-PRMS as Producing or Non-Producing.

Developed Producing Reserves

Developed Producing Reserves are expected to be recovered from completion intervals that are open and producing at the time of the estimate.

Improved recovery reserves are considered producing only after the improved recovery project is in operation.

RESERVES STATUS DEFINITIONS AND GUIDELINES

Page 2

Developed Non-Producing

Developed Non-Producing Reserves include shut-in and behind-pipe reserves.

Shut-In

Shut-in Reserves are expected to be recovered from:

(1) completion intervals which are open at the time of the estimate but which have not yet started producing;

(2) wells which were shut-in for market conditions or pipeline connections; or

(3) wells not capable of production for mechanical reasons.

Behind-Pipe

Behind-pipe Reserves are expected to be recovered from zones in existing wells which will require additional completion work or future re-completion prior to start of production.

In all cases, production can be initiated or restored with relatively low expenditure compared to the cost of drilling a new well.

UNDEVELOPED RESERVES (SEC DEFINITIONS)

Securities and Exchange Commission Regulation S-X §210.4-10(a)(31) defines undeveloped oil and gas reserves as follows:

Undeveloped oil and gas reserves are reserves of any category that are expected to be recovered from new wells on undrilled acreage, or from existing wells where a relatively major expenditure is required for recompletion.

(i) Reserves on undrilled acreage shall be limited to those directly offsetting development spacing areas that are reasonably certain of production when drilled, unless evidence using reliable technology exists that establishes reasonable certainty of economic producibility at greater distances.

(ii) Undrilled locations can be classified as having undeveloped reserves only if a development plan has been adopted indicating that they are scheduled to be drilled within five years, unless the specific circumstances, justify a longer time.

(iii) Under no circumstances shall estimates for undeveloped reserves be attributable to any acreage for which an application of fluid injection or other improved recovery technique is contemplated, unless such techniques have been proved effective by actual projects in the same reservoir or an analogous reservoir, as defined in paragraph (a)(2) of this section, or by other evidence using reliable technology establishing reasonable certainty.

Dear Ing. Morales:

In accordance with your request, we have audited the estimates prepared January 18, 2010, by Pemex Exploración y Producción (PEP), as of January 1, 2010, of the gross (100 percent) proved reserves in 25 Northeastern Marine Region fields in the Bay of Campeche, offshore west of the Yucatan Peninsula of Mexico. It is our understanding that the proved reserves estimates shown herein constitute approximately 48 percent of all proved reserves owned by PEP. We have examined the estimates with respect to reserves quantities, reserves categorization, and future producing rates, using the definitions set forth in U.S. Securities and Exchange Commission (SEC) Regulation S-X Rule 4-10(a). The estimates of reserves have been prepared in accordance with the definitions and guidelines of the SEC and conform to the FASB Accounting Standards Codification Topic 932, Extractive Activities—Oil and Gas. This report has been prepared for Petróleos Mexicanos’ use in filing with the SEC.

The following table sets forth PEP’s estimates of the gross (100 percent) reserves, as of January 1, 2010, for the audited properties:

Category	Gross (100 Percent) Reserves
	Crude Oil (MMBBL)	Condensate (MMBBL)	Plant Liquids (MMBBL)	Dry Gas(1) (MMBOE)	BOE (MMBBL)
Proved Developed Producing	3,579.2	77.8	86.7	168.1	3,911.8
Proved Developed Non-Producing	1,079.4	53.1	42.1	81.7	1,256.3
Proved Undeveloped	1,432.4	24.6	28.5	58.1	1,543.7
Total Proved	6,091.0	155.6	157.4	307.9	6,711.8

Totals may not add because of rounding.

⁽¹⁾ Dry gas reserves are the dry, sweetened gas available for sale by Pemex Gas y Petroquímica Básica at the tailgate of the processing plants.

Crude oil, condensate, plant liquids, and barrels of oil equivalent (BOE) volumes are expressed in millions of barrels (MMBBL); a barrel is equivalent to 42 United States gallons. Dry gas volumes are expressed in millions of barrels of oil equivalent (MMBOE), determined using dry gas conversion factors provided by PEP.

When compared on a field-by-field basis, some of the estimates of PEP are greater and some are less than the estimates of Netherland, Sewell International, S. de R.L. de C.V. However, in our opinion the estimates of PEP’s gross reserves shown herein are, in the aggregate, reasonable and have been prepared in accordance with generally accepted petroleum engineering and evaluation principles. These principles are set forth in the

1601 ELM STREET, SUITE 4500 Ÿ DALLAS, TEXAS 75201-4754 Ÿ PH: 214-969-5401 Ÿ FAX: 214-969-5411

Standards Pertaining to the Estimating and Auditing of Oil and Gas Reserves Information promulgated by the Society of Petroleum Engineers. We are satisfied with the methods and procedures used by PEP in preparing the January 1, 2010, estimates of reserves, and with consideration given to the variations on a field-by-field basis as noted above, we saw nothing of an unusual nature that would cause us to take exception with the estimates, in the aggregate, as prepared by PEP.

The estimates shown herein are for proved reserves only. PEP’s estimates do not include probable or possible reserves that exist for these properties. Reserves categorization conveys the relative degree of certainty; reserves subcategorization is based on development and production status. The estimates of reserves included herein have not been adjusted for risk.

Prices used by PEP are based on the 12-month unweighted arithmetic average of the first-day-of-the-month price for the period January through December 2009. All prices are held constant throughout the lives of the properties.

Lease and well operating costs used by PEP are based on historical operating expense records. These costs include district and regional overhead expenses along with costs incurred at the field level. No headquarters general and administrative overhead expenses of PEP or Petróleos Mexicanos are included. Lease and well operating costs are held constant throughout the lives of the properties. PEP’s estimates of capital costs are included as required for workovers, new development wells, and facilities, such as production equipment, pipelines, platforms, and nitrogen rejection plants. The future capital costs are held constant to the date of expenditure.

The reserves shown in this report are estimates only and should not be construed as exact quantities. Proved reserves are those quantities of oil and gas which, by analysis of engineering and geoscience data, can be estimated with reasonable certainty to be economically producible. If the reserves are recovered, the revenues therefrom and the costs related thereto could be more or less than the estimated amounts. Because of governmental policies and uncertainties of supply and demand, the sales rates, prices received for the reserves, and costs incurred in recovering such reserves may vary from assumptions made while preparing these estimates. Estimates of reserves may increase or decrease as a result of future operations, market conditions, or changes in regulations.

This audit was based on an independent reserves study of PEP’s oil and gas properties for 25 fields located in the Northeastern Marine Region. Our audit consisted primarily of a detailed review of all properties making up the total proved reserves in the Northeastern Marine Region. In the conduct of our audit, we have not independently verified the accuracy and completeness of information and data furnished by PEP with respect to oil and gas production, well test data, historical costs of operation and development, product prices, or any agreements relating to current and future operations of the properties and sales of production. However, if in the course of our examination something came to our attention that brought into question the validity or sufficiency of any such information or data, we did not rely on such information or data until we had satisfactorily resolved our questions relating thereto or had independently verified such information or data. We used standard engineering and geoscience methods, or a combination of methods, such as performance analysis, volumetric analysis, analogy, and reservoir modeling, that we considered to be appropriate and necessary to establish the conclusions set forth herein. Our audit did not include a review of PEP’s overall reserves management processes and practices.

In evaluating the information at our disposal concerning this audit, we have excluded from our consideration all matters as to which the controlling interpretation may be political, socioeconomic, legal, or accounting, rather than engineering and geoscience. As in all aspects of oil and gas evaluation, there are uncertainties inherent in the interpretation of engineering and geoscience data; therefore, our conclusions necessarily represent only informed professional judgment.

Supporting data documenting this audit, along with data provided by PEP, are on file in our office. The technical persons responsible for conducting this audit meet the requirements regarding qualifications, independence, objectivity, and confidentiality set forth in the Standards Pertaining to the Estimating and Auditing of Oil and Gas Reserves Information promulgated by the Society of Petroleum Engineers. We are independent petroleum engineers, geologists, geophysicists, and petrophysicists; we do not own an interest in these properties and are not employed on a contingent basis.

If the reserves are recovered, the revenues therefrom and the costs related thereto could be more or less than the estimated amounts. Because of governmental policies and uncertainties of supply and demand, the sales rates, prices received for the reserves, and costs incurred in recovering such reserves may vary from assumptions made while preparing these estimates. Estimates of reserves may increase or decrease as a result of future operations, market conditions, or changes in regulations.

This audit was based on an independent reserves study of PEP’s oil and gas properties for the 120 fields located in the Southern Region. Our audit consisted primarily of a detailed review of certain properties making up approximately 81 percent of the total proved reserves in the Southern Region. In the conduct of our audit, we have not independently verified the accuracy and completeness of information and data furnished by PEP with respect to oil and gas production, well test data, historical costs of operation and development, product prices, or any agreements relating to current and future operations of the properties and sales of production. However, if in the course of our examination something came to our attention that brought into question the validity or sufficiency of any such information or data, we did not rely on such information or data until we had satisfactorily resolved our questions relating thereto or had independently verified such information or data. We used standard engineering and geoscience methods, or a combination of methods, such as performance analysis, volumetric analysis, analogy, and reservoir modeling, that we considered to be appropriate and necessary to establish the conclusions set forth herein. Our audit did not include a review of PEP’s overall reserves management processes and practices.

In evaluating the information at our disposal concerning this audit, we have excluded from our consideration all matters as to which the controlling interpretation may be legal or accounting, rather than engineering and geoscience. As in all aspects of oil and gas evaluation, there are uncertainties inherent in the interpretation of engineering and geoscience data; therefore, our conclusions necessarily represent only informed professional judgment.

Supporting data documenting this audit, along with data provided by PEP, are on file in our office. The technical persons responsible for conducting this audit meet the requirements regarding qualifications, independence, objectivity, and confidentiality set forth in the Standards Pertaining to the Estimating and Auditing of Oil and Gas Reserves Information promulgated by the Society of Petroleum Engineers.

We are independent petroleum engineers, geologists, geophysicists, and petrophysicists; we do not own an interest in these properties and are not employed on a contingent basis.

Gentlemen:

Pursuant to your request, we have conducted a reserves audit of the net proved crude oil, condensate, natural gas liquids (NGL), and sales-gas reserves, as of January 1, 2010, of certain properties owned by Pemex Exploración y Producción (PEP) in the Región Marina Suroeste of Mexico. PEP has represented that these properties account for 13.5 percent on a net total liquids equivalent barrel basis of PEP’s net proved reserves as of January 1, 2010, and that the net proved reserves estimates have been prepared in accordance with the reserves definitions of Rules 4-10(a) (1)–(32) of Regulation S–X of the Securities and Exchange Commission (SEC) of the United States. We have reviewed information provided to us by PEP that it represents to be PEP’s estimates of the net reserves, as of January 1, 2010, for the same properties as those which we evaluated.

Reserves included herein are expressed as net reserves as represented by PEP. Gross reserves are defined as the total estimated petroleum to be produced from these properties after December 31, 2009. Net reserves are defined as that portion of the gross reserves attributable to the interests owned by PEP after deducting all interests owned by others.

Estimates of oil, condensate, NGL, and sales gas should be regarded only as estimates that may change as further production history and additional information become available. Not only are such reserves estimates based on that information which is currently available, but such estimates are also subject to the uncertainties inherent in the application of judgmental factors in interpreting such information.

DEGOLYER AND MACNAUGHTON

Data used in this audit were obtained from reviews with PEP personnel and PEP files. In the preparation of this report we have relied, without independent verification, upon such information furnished by PEP with respect to property interests, production from such properties, current costs of operation and development, current prices for production, agreements relating to current and future operations and sale of production, and various other information and data that were accepted as represented. A field examination of the properties was not considered necessary for the purposes of this report.

Methodology and Procedures

Estimates of reserves were prepared by the use of standard geological and engineering methods generally accepted by the petroleum industry. The method or combination of methods used in the analysis of each reservoir was tempered by experience with similar reservoirs, stage of development, quality and completeness of basic data, and production history.

When applicable, the volumetric method was used to estimate the original oil in place (OOIP) and the original gas in place (OGIP). Structure and isopach maps were constructed to estimate reservoir volume. Electrical logs, radioactivity logs, core analyses, and other available data were used to prepare these maps as well as to estimate representative values for porosity and water saturation. When adequate data were available and when circumstances justified, material balance and other engineering methods were used to estimate OOIP or OGIP.

Estimates of ultimate recovery were obtained after applying recovery factors to OOIP or OGIP. These recovery factors were based on consideration of the type of energy inherent in the reservoirs, analyses of the petroleum, the structural positions of the properties, and the production histories. When applicable, material balance and other engineering methods were used to estimate recovery factors. An analysis of reservoir performance, including production rate, reservoir pressure, and gas-oil ratio behavior, was used in the estimation of reserves.

For depletion-type reservoirs or those whose performance disclosed a reliable decline in producing-rate trends or other diagnostic characteristics, reserves were estimated by the application of appropriate decline curves or other performance relationships. In the analyses of production-decline curves, reserves were estimated only to the limits of economic production or to the limit of the production licenses as appropriate.

DEGOLYER AND MACNAUGHTON

Definition of Reserves

Petroleum reserves estimated by PEP and by us included in this report are classified by degree of proof as proved and are judged to be economically producible in future years from known reservoirs under existing economic and operating conditions and assuming continuation of current regulatory practices using conventional production methods and equipment. In the analyses of production-decline curves, reserves were estimated only to the limit of economic rates of production under existing economic and operating conditions using prices and costs consistent with the effective date of this report, including consideration of changes in existing prices provided only by contractual arrangements but not including escalations based upon future conditions. Proved reserves classifications by PEP and by us used in this report are in accordance with the reserves definitions of Rules 4-10(a) (1)–(32) of Regulation S–X of the SEC. The petroleum reserves are classified as follows:

Proved oil and gas reserves – Proved oil and gas reserves are those quantities of oil and gas, which, by analysis of geoscience and engineering data, can be estimated with reasonable certainty to be economically producible—from a given date forward, from known reservoirs, and under existing economic conditions, operating methods, and government regulations—prior to the time at which contracts providing the right to operate expire, unless evidence indicates that renewal is reasonably certain, regardless of whether deterministic or probabilistic methods are used for the estimation. The project to extract the hydrocarbons must have commenced or the operator must be reasonably certain that it will commence the project within a reasonable time.

(i) The area of the reservoir considered as proved includes: (A) The area identified by drilling and limited by fluid contacts, if any, and (B) Adjacent undrilled portions of the reservoir that can, with reasonable certainty, be judged to be continuous with it and to contain economically producible oil or gas on the basis of available geoscience and engineering data.

4

DEGOLYER AND MACNAUGHTON

(ii) In the absence of data on fluid contacts, proved quantities in a reservoir are limited by the lowest known hydrocarbons (LKH) as seen in a well penetration unless geoscience, engineering, or performance data and reliable technology establishes a lower contact with reasonable certainty.

(iii) Where direct observation from well penetrations has defined a highest known oil (HKO) elevation and the potential exists for an associated gas cap, proved oil reserves may be assigned in the structurally higher portions of the reservoir only if geoscience, engineering, or performance data and reliable technology establish the higher contact with reasonable certainty.

(iv) Reserves which can be produced economically through application of improved recovery techniques (including, but not limited to, fluid injection) are included in the proved classification when:

(A) Successful testing by a pilot project in an area of the reservoir with properties no more favorable than in the reservoir as a whole, the operation of an installed program in the reservoir or an analogous reservoir, or other evidence using reliable technology establishes the reasonable certainty of the engineering analysis on which the project or program was based; and (B) The project has been approved for development by all necessary parties and entities, including governmental entities.

(v) Existing economic conditions include prices and costs at which economic producibility from a reservoir is to be determined. The price shall be the average price during the 12-month period prior to the ending date of the period covered by the report, determined as an unweighted arithmetic average of the first-day-of-the-month price for each month within such period, unless prices are defined by contractual arrangements, excluding escalations based upon future conditions.

5

DEGOLYER AND MACNAUGHTON

Developed oil and gas reserves – Developed oil and gas reserves are reserves of any category that can be expected to be recovered:

(i) Through existing wells with existing equipment and operating methods or in which the cost of the required equipment is relatively minor compared to the cost of a new well; and

(ii) Through installed extraction equipment and infrastructure operational at the time of the reserves estimate if the extraction is by means not involving a well.

Undeveloped reserves – Undeveloped oil and gas reserves are reserves of any category that are expected to be recovered from new wells on undrilled acreage, or from existing wells where a relatively major expenditure is required for recompletion.

(i) Reserves on undrilled acreage shall be limited to those directly offsetting development spacing areas that are reasonably certain of production when drilled, unless evidence using reliable technology exists that establishes reasonable certainty of economic producibility at greater distances.

(ii) Undrilled locations can be classified as having undeveloped reserves only if a development plan has been adopted indicating that they are scheduled to be drilled within five years, unless the specific circumstances, justify a longer time.

(iii) Under no circumstances shall estimates for undeveloped reserves be attributable to any acreage for which an application of fluid injection or other improved recovery technique is contemplated, unless such techniques have been proved effective by actual projects in the same reservoir or an analogous reservoir, as defined in [section 210.4–10 (a) Definitions], or by other evidence using reliable technology establishing reasonable certainty.

DEGOLYER AND MACNAUGHTON

Primary Economic Assumptions

The following economic assumptions were used for estimating existing and future prices and costs:

Oil, Condensate, and NGL Prices

PEP has represented that the oil, condensate, and NGL prices were based on a 12-month average price (reference price), calculated as the unweighted arithmetic average of the first-day-of-the-month price for each month within the 12-month period prior to the end of the reporting period.

Natural Gas Prices

PEP has represented that the natural gas prices were based on a reference price, calculated as the unweighted arithmetic average of the first-day-of-the-month price for each month within the 12-month period prior to the end of the reporting period.

Operating Expenses and Capital Costs

Operating expenses and capital costs, based on information provided by PEP, were used in estimating future costs required to operate the properties. In certain cases, future costs, either higher or lower than existing costs, may have been used because of anticipated changes in operating conditions. These costs were not escalated for inflation.

While the oil and gas industry may be subject to regulatory changes from time to time that could affect an industry participant’s ability to recover its oil and gas reserves, we are not aware of any such governmental actions which would restrict the recovery of the January 1, 2010, estimated oil and gas volumes. The reserves estimated in this report can be produced under current regulatory guidelines.

DEGOLYER AND MACNAUGHTON

PEP has represented that estimated net proved reserves attributable to the reviewed properties are based on the definitions of proved reserves of the SEC. PEP represents that its estimates of the net proved reserves attributable to these properties which represent 13.5 percent of PEP’s reserves on a total liquids equivalent basis are as follows, expressed in thousands of barrels (Mbbl), millions of cubic feet (MMcf):

	Estimated by PEP Net Proved Reserves as of January 1, 2010
	Oil and Condensate (Mbbl)	NGL (Mbbl)	Sales Gas (MMcf)	Total Liquids Equivalent* (Mbbl)
Properties reviewed by DeGolyer and MacNaughton
Mexico
Proved Developed	664,471	108,007	1,027,284	969,998
Proved Undeveloped	535,099	117,876	1,398,304	921,831
Total Proved	1,199,570	225,883	2,425,588	1,891,829

* Total liquids equivalent volumes are based on heating values that vary for each field.

In our opinion, the information relating to estimated proved reserves of oil, condensate, natural gas liquids, and gas contained in this report has been prepared in accordance with Paragraphs 932-235-50-4, 932-235-50-6, 932-235-50-7 and 932-235-50-9 of the Accounting Standards Update 932-235-50, Extractive Industries – Oil and Gas (Topic 932): Oil and Gas Reserve Estimation and Disclosures (January 2010) of the Financial Accounting Standards Board and Rules 4–10(a) (1)–(32) of Regulation S–X and Rules 302(b), 1201, 1202(a) (1), (2), (3), (4), (8), and 1203(a) of Regulation S–K of the Securities and Exchange Commission.

DEGOLYER AND MACNAUGHTON

In comparing the detailed net proved reserves estimates prepared by us and by PEP, we have found differences, both positive and negative. It is our opinion that the net proved reserves estimates prepared by PEP on the properties reviewed by us and referred to above, when compared on the basis of net total liquids equivalent barrels, in aggregate, differ by 9 percent and are considered to be reasonable. DeGolyer and MacNaughton is an independent petroleum engineering consulting firm that has been providing petroleum consulting services throughout the world for over 70 years. DeGolyer and MacNaughton does not have any financial interest, including stock ownership, in PEP. Our fees were not contingent on the results of our evaluation. This letter report has been prepared at the request of PEP. DeGolyer and MacNaughton has used all procedures and methods that it considers necessary to prepare this report.
