WorldCom, Inc. and Telecomunicaciones De Mexico Sign Agreement To Jointly Offer Frame Relay Services

JACKSON, Miss. (July 22, 1996) --

WorldCom International, a business unit of WorldCom, Inc., recently
signed an agreement with Telecomunicaciones de Mexico (Telecomm) to
extend frame relay services to various cities of Mexico. The
network-to-network interface agreement interconnects the WorldCom
International and Telecomm public frame relay networks.

WorldCom International will expand its current service to Mexico,
adding Puebla and numerous remote cities where its customers'
Mexico operations are based. Also, Telecomm customers will send
critical data traffic northbound to connect with the WorldCom
International frame relay network which then will distribute the
traffic to key financial centers throughout the world.

"We are pleased to have signed an agreement of this magnitude
with Telecomunicaciones de Mexico," said Richard Gibbens, vice
president of WorldCom International data services. "We have a
long-standing relationship with this administration as together we
have provided telecommunications services for many years. We look
forward to continuing this relationship by giving customers of both
organizations high-quality frame relay network services
worldwide."

Telecomm, the government-owned satellite organization, and
WorldCom International entered into another agreement at the Global
Traffic Meeting in Washington, D.C. The U.S.-based company signed a
modified agreement for general satellite interconnection
services.

"The combination of the satellite agreement and this new
frame relay interconnection agreement shows the strength of this
relationship that has developed over the past 60 years with
Telecomm," said Michael Sauer, WorldCom International executive
vice president international relations. "Both organizations are
committed to providing end users with the finest telecommunications
services available today."

Initially, Telecomm will originate its customers' frame relay
traffic via satellite from four major cities -- Mexico City,
Guadalajara, Monterrey and Puebla. The traffic then will be placed on
terrestrial fiber-optic facilities northbound to the interconnection
point along the U.S.-Mexico border. Traffic then will ride the
WorldCom International frame relay fiber-optic network to the point
of destination. Later in the year, Telecomm is scheduled to extend
its frame relay network into Cancun, Ciudad Juarez, Tijuana and
Puerto Vallarta.

Primary frame relay users are multinational firms which require
high-speed data communications between manufacturing operations,
software and hardware equipment vendors and financial institutions
located throughout the world.

"Companies expanding their operations into international
markets become highly dependent on quality telecommunication services
including frame relay," Gibbens explained. "Companies are
looking for cost-efficient, flexible and reliable data communications
services which span the world to support their mission-critical data
applications needs. Many times, frame relay is the best answer.

"We believe with the growth of telecommunications in Mexico
and the North American Free Trade Agreement, frame relay is one
answer to provide high-speed data solutions for customers."

WorldCom International's frame relay network, with connections
between 56K and T-1 in the U.S., and 56K to E-1 in countries where
E-1 is available, is accessible throughout Europe, the Pacific Rim
and North America.

WorldCom, Inc. is one of the largest long distance
telecommunications companies in the United States offering domestic

company operates a diverse international network of fiber-optic
submarine cable and transmission services and provides numerous
