     ATLANTA, Feb. 14 /PRNewswire/-- World Access, Inc. (Nasdaq: WAXS)
announced today that it has signed a definitive merger agreement with
Communication TeleSystems International d/b/a WorldxChange Communications
("WorldxChange"), a private multinational telecommunications service provider.
Operating 45 switches in 12 countries, WorldxChange offers an array of
telecommunications services concentrating on the needs of its business and
residential customers. WorldxChange generated pro-forma revenues in 1999 of
approximately $600 million, through its primary operations in North America,
Germany, the United Kingdom, France, the Netherlands, Belgium, Australia and
New Zealand.

      Pursuant to the terms of the agreement, shareholders of WorldxChange will
receive approximately 31 million shares of World Access common stock, subject
to adjustment under certain circumstances. In addition, World Access will
assume approximately $225 million in WorldxChange debt. The transaction, which
is expected to close by the end of the second quarter, is subject to, among
other things, certain regulatory approvals and the approval of the shareholders
of World Access and WorldxChange. The merger is intended to qualify as a
tax-free reorganization, and will be accounted for as a purchase transaction.
World Access has agreed to provide bridge financing to WorldxChange in an
amount up to $30 million. WorldxChange will be entitled to elect one director to
the World Access Board of Directors.

      John D. Phillips, Chairman and Chief Executive Officer of World Access,
said, "Our acquisition of WorldxChange represents a major step forward in our
plans to be a leader in enhanced retail telecommunications services throughout
Europe. WorldxChange has a significant presence in key European markets such as
the UK, Germany and the Benelux, principally serving SME customers. More
importantly, WorldxChange has developed state-of-the-art, Internet-based
information management systems, incorporating all key aspects of retail telecom
services, including provisioning, billing, fraud protection and customer care.
We believe these capabilities are among the finest in the industry, and will
serve as the foundation for our retail management systems throughout Europe. In
addition to the impressive systems and significant network assets, WorldxChange
has a talented and dedicated management team that will play a key role in our
strategic development."

      Walt Anderson, Chairman of WorldxChange, commented, "This is an exciting
opportunity for WorldxChange to become part of a company that is focused on
leading the consolidation of the fragmented European telecom industry. Our
retail and wholesale volumes and expertise, combined with the significant scale
and network assets of World Access, will help to solidify World Access'
position as a leading provider of bundled voice, data and Internet services
to SME markets in Europe. We anticipate that our integration into World Access
will result in significant cost savings in the areas of network costing, least
cost routing, network operations, and some general and administrative costs. We
expect that these savings, together with enhanced product offerings, will
further increase our competitiveness as we continue to rapidly grow our
European and Pacific retail operations."

      "The combination of World Access with NETnet, Star and WorldxChange,"
continued Mr. Phillips, "creates one of the largest independent telecom

   2

service companies focused on the European market. The network strengths,
attractive retail customer bases, developed sales organizations, and
significant traffic tonnage and scale of these operations significantly
accelerates our strategic development."
