                         reduction in gas imports and the generation of economic
                         well being in the northeast of the country.

REYNOSA, Tamps.- Petroleos Mexicanos started in this city the works of the first
four blocks of the Multiple Service Contracts (CSM) of the Burgos Basin. These
will allow increasing the national production of natural gas to nearly 400
million cubic feet per day. It will also reduce natural gas imports and generate
an economic well being that will have an important impact in the northeast of
the country.

In representation of the Director General of Petroleos Mexicanos, Raul Munoz
Leos, the Director General of PEMEX Exploration and Production, Luis Ramirez
Corzo, considered that the start of these Works, under the Multiple Service
Contracts, mark a decisive moment in the relationships of PEMEX with the
national and international oil industry.

He underlined that with the formal beginning of these works in the Burgos Basin,
the efforts of two years of intense works are concluded, and a new relationship
starts in which PEMEX will be strengthened with the success of the participant
companies.

He recognized that the Multiple Service Contracts represent a unique opportunity
for the growth and consolidation of PEMEX, which shall not waive the
responsibility the nation has put into it.

The scheme of the Multiple Service Contracts, he said, is a tool to increase the
production of natural gas and reduce imports, with the application of the state
of the art technology, of the best execution and financing practices to benefit
the country.

On his part, the Executive Director of the Multiple Service Contracts of PEMEX
Exploration and Production, Sergio Guaso, highlighted the importance of this
event. He expressed that with the starting of the Burgos Basin works it is
reaffirmed that the international experience and the technical reputation of the
companies winning the contracts guaranty PEMEX the efficient execution of the
works of the Reynosa-Monterrey, Cuervito, Mision and Fronterizo blocks.

The representatives of the consortiums, Roberto de Toledo of PTD Multiple
Services, formed by Petroleo Brasileiro, Teikoku and Grupo Diavaz; Julio Vieriro
of Burgos Multiple Services, formed by Techint, Tecpetrol and Industrial
Perforadora Campeche; and Guillermo Alvarezof Repsol Exploracion Mexico, which
won the bid of the first blocks of the Multiple Services Contracts, presented
the organization and the equipment that they have to develop the works.

         During their interviews, the representatives of these companies
concurred that the project is beneficial for the communities, for PEMEX and for
the companies.
