# ASUR ANNOUNCES THE TRANSFER OF TRIBASAS STAKE IN INVERSIONES Y 
TÉCNICAS AEROPORTUARIAS TO NACIONALFINANCIERA

Mexico City, January 8, 2004, Grupo
Aeroportuario del Sureste, S.A. de C.V. (NYSE: ASR; BMV: ASUR) (ASUR) announced the
transfer of Triturados Basálticos y Derivados, S.A. de C.V. (Tribasa) shares
in ASURs strategic partner, Inversiones y Técnicas Aeroportuarias, S.A. de
C.V. (ITA) to Nacional Financiera, S.N.C (NAFIN).

ITA, whose capital stock was held by
four shareholders, Copenhagen Airports, Tribasa, Concesiones de Infraestructuras de
Transporte, S.A. (Cintra), Groupe GTM, S.A. became ASURs strategic partner when it
acquired 15% of ASURs capital in 1998 as part of the privatization of the airport
system in Mexico.

According to the original agreements
signed by ASUR and the Mexican Federal Government, Copenhagen Airports, acting as
ITAs operating partner, and Tribasa, acting as the Mexican partner, were required to
maintain their ownership stake in ITA for 15 years (except for transfers permitted under
certain conditions provided in such agreements). These conditions were satisfied in
connection with Tribasas transfer to NAFIN, and the transfer was approved by
ASURs shareholders during its General Ordinary and Extraordinary Shareholders
Meeting held on December 30, 2003.

Tribasas transfer of its stake
in ITA to NAFIN was carried out as part of Tribasas settlement with its creditors.
As a result, NAFIN is now ITAs temporary Mexican partner, until its ownership stake
is sold to another shareholder, who meets the requirements to be part of ITA as its
Mexican partner.
