at Employees' Fingertips Anywhere and Anyplace

READING, United Kingdom, 16 December 2004 - MCI (NASDAQ: MCIP) today announced that it has been selected to deliver Internet services for Airbus. MCI will expand the existing relationship to Airbus SAS by providing a set of advanced Internet-based digital communication services in France, the United Kingdom, Germany, Russia, China and the United States.

The MCI solution increases the efficiency of Airbus's communications infrastructure by introducing a broad range of new all-digital Internet access services for the company's nomad employees across the globe, including traditional PSTN/ISDN technologies but also mobile technologies such as GSM and GPRS, hot-spot services such as WiFi, as well as broadband, including DSL and LAN-to-LAN connectivity. Those technologies enable Airbus to provide its employees access to business resources from anywhere in the world making real time information access a reality. Initially, more than 5,000 nomad users of Airbus France will get immediate and direct access to the Airbus corporate network with security supported by tunneling technology and strong authentication. The service will then be extended to additional 3,000 employees of Airbus in other countries.

"Our aim was to increase the competitiveness of our company," says Pierre Nelkin, head of IS Services & Subcontracting General Procurement for Airbus. "This meant that we had to be able to provide all our staff with easy and quick access to information resources, wherever they are in the world. Our company has a global presence and we will rely on the expanding MCI IP network to securely route all the information required for the applications and processes that make Airbus a leader on its market."

Under the terms of the agreement, the offer may also be extended to additional EADS subsidiaries to enable them to use the global MCI solution.

"MCI has a long and successful relationship with Airbus providing the company advanced communication services. The new contract will enable us to offer Airbus an integrated set of solutions combining the existing voice services with new and innovative Internet capabilities driving efficiency and productivity for Airbus," says Jean-Francois Rallet, Vice President Sales and Service Southern Region for MCI in Europe, the Middle East and Africa.
