[Translated from Spanish] MINISTRY OF COMMUNICATIONS AND TRANSPORATION

Concession granted by the Federal Government, through the Ministry of Communications and Transportation in favor of Ferrocarril del Noreste, S.A. de C.V., pursuant to the following antecedents and conditions.

On March 2, 1995 the amendment to the fourth paragraph of article 28 of the Political Constitution of the United Mexican States was published at the Official Gazette of the Federation in order to substitute the regime of exclusive participation of the State in rail transportation services, for a regime that would allow the participation of private entities and, as a consequence thereof, on May 12 of such year the Railway Service Regulatory Law (Ley Reglamentaria del Servicio Ferroviario) was enacted with the purpose of setting forth the fundamental regulatory framework for such activity.

The Inter-ministerial Commission of De-incorporation approved the scheme to perform the restructuring of the railroad system, through its Ruling of July 18, 1995, which consisted in the regional segmentation of the Mexican railroad service in order to conform three principal lines: pacific-north, northeast and southeast, as well as a terminal of interconnection services and maneuvers in the Valley of Mexico.

The Ministry of Comptrollership and Administrative Development (Secretaría de Contraloría y Desarrollo Administrativo), through its Ruling published at the Official Gazette of the Federation of November 29, 1996, allocated to the service of the Ministry of Communications and Transportation the real estate properties that constitute the general communication route of the Northeast, as well as the real estate properties where the facilities for auxiliary services are located, in order for such Ministry to grant over such real estate properties the respective concessions and permits, in terms of that set forth in the Railway Service Regulatory Law.

The Ministry of Finance and Public Credit (Secretaría de Hacienda y Crédito Público), with the previous favorable opinion of the Inter-ministerial Commission of Expenses and Financing, authorized the incorporation Ferrocarril del Noreste, S.A. de C.V. as an entity with a majority of State participation, which corporate purpose consists mainly in the operation and exploitation of a general railroad communication route and in providing rail transportation services.

Ferrocarril del Noreste was incorporated as a limited liability company with variable capital (sociedad anónima de capital variable), pursuant to the laws of Mexico, as evidenced in public deed number 50,413, of November 22, 1996, witnessed by Mr. Miguel Alessio Robles Landa, Notary Public number 19 of the Federal District, which first official copy is being registered at the Public Registry of Commerce of Monterrey, Nuevo León.
