On the margin, a seal with the National Emblem that states: United Mexican States- Presidency of the Republic.

FELIPE DE JESÚS CALDERÓN HINOJOSA, President of the United Mexican States, exercising the authority granted to me under Article 89, Section I, of the Constitución Política de los Estados Unidos Mexicanos (Political Constitution of the United Mexican States), and pursuant to Article 25, paragraph four, and Article 28, paragraph five, of the aforementioned Constitution; Article 4, paragraph one, of 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); Article 1, last paragraph, Article 2, Article 3, paragraph two, and the Third Transitory Provision, paragraph one, of the Ley de Petróleos Mexicanos (Petróleos Mexicanos Law); Article 3, paragraph four of the Ley Federal de las Entidades Paraestatales (Federal Law of Decentralized Public Entities); and Articles 31, 33, 37 and 45 of the Ley Orgánica de la Administración Pública Federal (Federal Public Administration Organic Law); and

PREAMBLE

Whereas the Political Constitution of the United Mexican States grants the Government exclusive authority to exercise all activities in the strategic areas of petroleum and all other hydrocarbons, as well as basic petrochemicals;

Whereas on November 28, 2008 a decree enacting the Petróleos Mexicanos Law was published in the Diario Oficial de la Federación (Official Gazette of the Federation) that adds to Article 3 of the Law of Decentralized Public Entities; Article 1 of the Ley de Obras Públicas y Servicios Relacionados con las Mismas (Law of Public Works and Related Services); and adds a third paragraph to Article 1 of the Ley de Adquisiciones, Arrendamientos y Servicios del Sector Público (Law of Acquisitions, Leasing and Services of the Public Sector);

Whereas the duties and other activities that the Government exercises exclusive authority over in the strategic areas of petroleum and all other hydrocarbons, as well as basic petrochemicals, the manufacturing of petrochemical products other than basic petrochemicals, as well as their transportation, storage, distribution and marketing, correspond to Petróleos Mexicanos, through its subsidiary entities which are Pemex-Exploración y Producción, Pemex-Refinación, Pemex-Gas y Petroquímica Básica, and Pemex-Petroquímica;

Whereas the Third Transitory Provision of the Petróleos Mexicanos Law establishes that the Federal Executive shall issue decrees for the reorganization of the existing subsidiary entities of Petróleos Mexicanos, based on a proposal submitted to such effect by the Board of Directors of the aforementioned decentralized entity;

Whereas the Board of Directors of Petróleos Mexicanos, through its Director General, has submitted for consideration of the Federal Executive a proposal to maintain the current structure of Petróleos Mexicanos based on the four subsidiary entities mentioned above;

Whereas the decision of the above-mentioned governing body corresponds to Petróleos Mexicanos’s framework of autonomy to decide its internal organization, in order to respond in the most appropriate manner to the duties entrusted to it;

Whereas the reorganization of the subsidiary entities of Petróleos Mexicanos is based on an institutional model with certain characteristics, among them, Petróleos Mexicanos’ continuing authority to

direct the central planning and strategic management of the subsidiary entities as set forth in the Petróleos Mexicanos Law, and its commitment to provide general corporate services of an administrative and technical nature, as required by the subsidiary entities;

Whereas within the aforementioned institutional model the subsidiary entities shall continue to undertake all activities related to technical and industrial operations, in accordance with their purpose, that is, those activities that are strictly productive and commercial in nature;

Whereas the aforementioned institutional model distinguishes the assignment of authority and duties related to central planning and strategic management, as well as the specialized and general administrative services provided by Petróleos Mexicanos, from the core productive activities undertaken by the subsidiary entities, which enables these entities to focus their resources, efforts and time on undertaking and specializing in the activities and productive and marketing processes that generate economic value;

Whereas in accordance with the foregoing, the subsidiary entities shall not diverge from their efforts by undertaking other types of duties that, under this institutional, administrative and corporate model, shall be performed by Petróleos Mexicanos;

Whereas the organization continues to subdivide the duties corresponding to each subsidiary entity in accordance with the rationale of distributing core activities of productive character as referred to in the Petróleos Mexicanos Law; and

Whereas in this respect, the activities relating to petrochemical products, distinct from basic petrochemicals, must be undertaken by the subsidiary entities, and such products shall continue to be manufactured by the subsidiary entity Pemex-Petroquímica, notwithstanding undertakings by the private sector, pursuant to the Regulatory Law to Article 27 of the Political Constitution of the United Mexican States Concerning Petroleum Affairs, I have issued the following:
