WorldCom, SembCorp And Singapore MRT Form Consortium To Bid For Second Telecom License In Singapore

SINGAPORE (May 30, 1997) WorldCom, Inc.

(Nasdaq/NM:WCOM) SembCorp Ltd and Singapore MRT Ltd (SMRT) announced
today that they have joined forces to enter a joint bid for a Public
Basic Telecommunication Services License ("the License") to
be issued by the Telecommunication Authority of Singapore in 1998.

The three companies, who have been in close discussions for over a
year, bring together complimentary strengths, which combined create a
Consortium that can be a significant telecommunications competitor in
the region.

WorldCom is one of the fourth largest long distance
telecommunications companies in the United States. It also owns the
world's biggest ISP, UUNET Technologies.

WorldCom has proven experience and success in pioneering the
development of competitive local, long distance and international
telecommunications services in the U.S. and across Europe, where it has
been at the forefront of regulatory change. It has also designed, built
and operates fiber-optic telecommunication networks in over 40 cities
in the US and Europe. In addition to its 20,000 mile fiber-optic
network spanning the U.S., the company is making major investments in
strategic long distance, cross border networks. These include a 20
gigabit transatlantic cable system and a pan-European fiber-optic
network. Both of these new systems are due to be operational in early
1998.

SembCorp has extensive experience in engineering and the
construction of large-scale infrastructure projects in Singapore and
abroad and is well placed to support a smooth and rapid roll-out of the
telecommunication infrastructure. SembCorp is also a premier multimedia
player with business information technology, particularly related to
the Internet.

SMRT's tunnel and viaduct network throughout the island will
provide ideal routes for cabling and sites for collocation of
telecommunication equipment. SMRT has already deployed a fiber-optic
network for its own telecommunication needs. The company's strong
service culture will provide a further asset to the Consortium.

"WorldCom's mission is to be the premier supplier of
telecommunications to customers world wide," said Mr. Bernard J.
Ebbers, Chairman and Chief Executive Officer of WorldCom, Inc.
"Singapore is a recognized world center for business and trade and
we are very pleased to have the opportunity to join with such strong
Singapore companies in our bid to deliver world class
telecommunications services. Our goal is to replicate both the quality
of service to customers and the resulting commercial success we have
enjoyed in the U.S. and in Europe."

"WorldCom is setting the agenda for a competitive
telecommunications market world wide. It is time for new, dynamic
players in this burgeoning market to set the stage for the next
millennium. The natural choice for Singapore is a consortium whose
entrepreneurial vigor is demonstrated by a proven track record in
successfully rolling out innovative and competitive customer-focused
services," said Mr. Colin Williams, Executive Vice President,
International, WorldCom.

SembCorp's Chairman, Mr. Philip Yeo, described the Consortium as
a new breed of constructive and vibrant competitor. "Vibrant
because we aim to breathe vitality into the telecommunications industry
. Our vision is to develop a state-of-the-art telecommunications
infrastructure and provide the best services at competitive prices
without compromise on the quality of service. Constructive because we
want to participate in developing Singapore into a thriving regional
and international telecommunications hub," said Mr. Yeo. He added
that SembCorp's entry into telecommunications was part of the
conglomerate's strategy to build an integrated information
technology group encompassing multimedia/Internet, systems integration
and telecommunications.

Said Mr. Goh Kim Leong, Chairman of SMRT: "With a decade of
experience in operating the Mass Rapid Systems in Singapore, SMRT is
ready to develop new businesses that compliment the strength and
competitive advantages of our organization. We think that
telecommunications will be a natural fit for our diversification plans.
"

WorldCom will have a 35% stake in the Consortium. SembCorp and SMRT
will hold the remaining 65%.
