MCLEAN, Va.--(BUSINESS WIRE)--April 15, 2004--PRIMUS Telecommunications Group, Incorporated (Nasdaq:PRTL)(PRIMUS), a global telecommunications service provider offering an integrated portfolio of voice, Internet, voice over Internet protocol (VOIP), data and hosting services, announced today that PRIMUS Telecommunications Canada, Inc. (PRIMUS Canada), its wholly owned subsidiary in Canada, acquired Magma Communications Ltd (Magma), a leading provider of Internet solutions to corporate, government and residential customers in Toronto, Ottawa and Montreal. Magma's product offerings include Web hosting, server co-location and managed services (system administration and security), and Internet access. PRIMUS Canada will acquire 100% of the issued stock of Magma for a total consideration of approximately C$16 million, half of which will be payable from available cash and the balance in shares of Common Stock of PRIMUS.

The acquisition adds approximately 30,000 customers to PRIMUS Canada's existing Internet customer base of over 70,000 and significantly expands its network and operations in Ottawa where Magma operates a 7,000 square foot Data Center. "We believe Magma provides an excellent infrastructure to enhance our existing Internet and Data Center business, particularly to government and corporate accounts," said Ted Chislett, President and Chief Operating Officer of PRIMUS Canada.

Founded in 1995, Magma has earned a reputation for providing quality customer service, winning the Consumers Choice Award for Internet Service Providers in Ottawa seven years in a row. Magma has also experienced consistent revenue growth with a five-year average annual growth rate of over 30%.

K. Paul Singh, Chairman and Chief Executive of PRIMUS, stated: "We have previously articulated the essential criteria we have established for acquisitions - they have to add scale in our existing major markets, they should be focused on growing our retail customer base, and they need to be accretive to our operating profitably and cash flow. The Magma acquisition meets all of those measures, as well as broadening our service offerings and targeted customers. In addition, Magma's customer base presents opportunities for bundling our VOIP and voice products."
