Cable & Wireless Selects Priority Call to Expand Global Calling Card Business.

WILMINGTON, Mass.--(BUSINESS WIRE)--July 20, 1999--

Priority Call Named Group Standard Supplier in Deal That Strengthens C&W's Ability to Compete in International Postpaid and Prepaid Market

Priority Call Inc. announced today that it has been selected by Cable & Wireless, Global Card Services to provide equipment and services to support expansion of its postpaid and prepaid calling card businesses around the globe.

The deal will effectively enhance Cable & Wireless' ability to compete in one of the fastest-growing sectors of the international telecommunications market.

Cable & Wireless already has millions of calling cardholders worldwide. Utilizing the new global database technology developed by Priority Call to enhance its ORYX(R) service node, Cable & Wireless will be able to offer customers what are essentially "roaming card" services. This will allow users to place long distance telephone calls using the same card, whether they are in London, Chicago, or Sydney.

Since the ORYX system doesn't require that the call be trunked back to the home node, the calls are more efficiently and cost effectively placed through the Cable & Wireless network.

This agreement represents the first of three Priority Call systems to be installed in Cable & Wireless' expanding global network. The first node was installed in the United Kingdom in late 1998. The additional platforms are to be deployed in the near future, and are important benchmarks in Cable & Wireless' efforts to globalize and brand its calling card business.

"It is important for us to have a platform supplier that can allow us to expand capabilities in this evolving market," said Phil Mehrtens, development and operations director of Cable & Wireless' Global Card Services division. "With Priority Call, we will be able to implement innovative systems that allow Cable & Wireless to offer customers cost-effective global calling card options."

"Cable & Wireless is an emerging force in the international calling card business," commented Lois Andreasen, vice president of marketing for Priority Call. "Utilizing innovative technologies will expand the reach of its vast communications resources, allowing the company to effectively compete with other network-based carriers."
