Telegroup Acquires South East Telecom and Corporate Networks.

FAIRFIELD, Iowa--(BUSINESS WIRE)--June 10, 1998--As part of its growing U.K. presence, Telegroup(R), Inc. (Nasdaq: TGRP), a leading global telecommunications provider, has acquired the Corporate Networks group of companies, including South East Telecom Limited and its affiliate, Phone Centre Communication (Service) Limited. South East Telecom offers telecommunications services under the Corporate Networks brand name.

Telegroup UK Managing Director Gary Muchmore said: "The acquisition of the Corporate Networks group of companies is consistent with our strategy to expand our U.K. market share by offering corporate customers a broad range of low cost international and national telecommunications services."

Telegroup, Inc.'s Senior Vice President, Global Retail Businesses and Services, Eric Stakland, commented: "Telegroup recently demonstrated its commitment to the U.K. market by increasing our ownership of transatlantic bandwidth capacity more than 30 times, by purchasing an STM-1 on the Gemini (New York - London) cable system. This enables us to provide our U.K. customers with lower cost services, greater access to Telegroup's global switching network, and redundant routing capability in the event of cable failure. We are very pleased to be able to offer these advantages to existing and future Corporate Networks customers."

Mr. Muchmore continued: "We see Corporate Network's existing dealer distribution network as an ideal base upon which to expand our corporate distribution through attractive channel incentives."
