Primus ACQUIRES 1492 TECHNOLOGIES TO GAIN LEADING-EDGE E-COMMERCE AND WEB SERVICES CAPABILITIES 

McLean, VA, November 22, 1999 -- Primus Telecommunications Group, Incorporated (Nasdaq: PRTL), a facilities-based global communications company offering a portfolio of bundled domestic and international voice, data and Internet services, announced today it has acquired the business of closely held 1492 Technologies LLC of Alexandria, VA. For more than three years, 1492 Technologies has been working with businesses in the planning, design, implementation and management of their web activities and enabling e-commerce applications. The entire management and key staff of 1492 Technologies will remain with the company. Terms of the acquisition were not disclosed.

"One of the most important trends over the next five years will be the entrance of small and medium-sized enterprises (SMEs) into the Digital Economy. The acquisition of 1492 Technologies enhances Primus’s plan to be a major provider of critical services to this customer segment," said K. Paul Singh, Chairman and Chief Executive Officer of Primus. "As businesses increasingly use Internet technologies to deliver the productivity benefits of intranets, extranets and e-commerce, Primus will be positioned to provide the connectivity, hosting and interactive architecture to bring wired business plans alive."

"Teaming with Primus provides us with the resources and capabilities to capitalize on a vast domestic and international market opportunity," said Ted Reynolds, co-founder of 1492 Technologies. "Primus’s expanding global ISP operations and its position as an enabler of e-commerce solutions for businesses are compelling for the prosperity of 1492, which specializes in helping companies compete in the Net Economy."

With the addition of 1492 Technologies (www.mxdii.com), Primus customers will receive end-to-end life-cycle management for their online presence. Clients will be able to rely on Primus to develop their Internet operations, network management and hosting services, and work with them to evolve their web presence as new technologies become available. 1492 Technologies provides a foundation of Professional Solutions Services from which to support customers and their applications that are increasingly being deployed in a network-centric manner, thus taking advantage of the efficiency Internet technologies allow.

1492 Technologies recently won Vice President Al Gore’s prestigious "Hammer Award" as part of the Access America team, working to reduce waste in government. Additionally, 1999 marks the second consecutive year in which 1492 Technologies was named as one of the US’s top web design companies by ChannelSeven Communications, a respected industry resource focused on web design and consulting firms. Clients of 1492 Technologies encompass a nationally arrayed list of large and small corporations in the financial services, media, entertainment, telecommunications and manufacturing industries, government, public sector and non-profit organizations, and Internet start-ups.
