Cambridge Telcom Report, April 17, 2000

WINSTAR COMMUNICATIONS, INC. (NASDAQ: WCII) Tuesday announced that its advanced, high-speed broadband capabilities will be made available in the commercial buildings owned by Cofinimmo SA, a leading listed property company in Belgium. This is Winstar's first building access rights agreement with a major portfolio owner based outside of the United States.

Under the terms of the agreement, Winstar is permitted to offer its broadband services, which include high-speed Internet and data, Web-based information and local and long distance services, to Cofinimmo's portfolio of 86 office buildings. Cofinimmo owns buildings in several key business markets throughout Belgium.

The agreement also allows Winstar to install hub sites on existing and future Cofinimmo buildings. Winstar will be able to provide its state-of-the-art broadband services to both Cofinimmo properties and other major office facilities located in the vicinity of the hub buildings, without relying on access to the copper-wire local loops operated by other carriers.

"The Cofinimmo agreement is a clear illustration of Winstar's successful strategy to replicate our proven U.S. business model in the international marketplace," said Richard J. Uhl, president and chief operating officer of Winstar for Buildings. "We look to build on the momentum of this achievement with similar deals in the future."

"We are pleased to be working with Cofinimmo to bring the very best in advanced, end-to-end broadband communications services to their tenants," said David Ralston, senior vice president and managing director of Winstar Europe. "This agreement provides us with access to premier buildings in a key Winstar market."

"Cofinimmo is a customer-focused company and the agreement with Winstar enables us to increase our level of service to our customers," said Jean Franken, chief executive of Cofinimmo. "It is an opportunity to equip our customers with the best available technology and provide them with a more productive business environment."

Winstar works with commercial building owners and managers to provide tenants with a wide range of e-business solutions - including data, voice, videoconferencing, Web hosting and applications services - through its broadband network.
