Private Mexican operator Satelites
Mexicanos S.A. de C.V. (Satmex) has selected Europe’s Ariane to launch its
Satmex 6 satellite from the European Spaceport in Kourou, French Guiana,
during the first quarter of 2003. The launch contract should be signed

Satmex 6, a Space Systems/Loral-built satellite, is currently under
construction at SS/L’s facilities in Palo Alto, California. Weighing
approximately 5,700 kilograms at liftoff, the satellite will be positioned at
109.2 degrees West and carry 36 C-band and 24 Ku-band transponders. Satmex
will use the state-of-the-art Satmex 6 satellite to bolster its
telecommunications and Internet transmission capacity for all of Mexico, as
well as other parts of North America and Latin America.

“This choice once again demonstrates our adaptability and flexibility,”
said Jean-Marie Luton, Chairman and CEO of Arianespace, emphasizing the
importance of Satmex’s decision. “Today, only Arianespace and Ariane 5 give
operators fast access to space for their heavy satellites. We are extremely
proud of our role in building the Mexican telecommunications system, and of
Satmex’s renewed confidence in us. This will be the fourth Mexican satellite
launched by Arianespace, and the second for Satmex, following Satmex 5, which
was launched on Flight 114 in December 1998.”

“Our team selected Ariane after a thorough evaluation of all possible
Satmex 6 launch options,” said Lauro Gonzalez, president, Satmex. “Ariane
provides Satmex with the most reliable solution to launch what will be the
largest and most important satellite for Satmex and Mexico.”
