CTC Continues Branch Sales Office and Network Expansion

CTC Communications Group Inc. (NASDAQ NM: CPTL)--a rapidly expanding provider of state-of-the-art integrated communications solutions for medium-to-large enterprises-- announced that it has installed and activated its Integrated Communications Network called IntelliNET(SM), in Philadelphia, PA. and Baltimore, MD. to serve business customers in these metro and surrounding areas as the Company continues its geographic expansion along the East Coast.

In advance of this network expansion, CTC already opened and staffed three sales offices in the eastern Pennsylvania region and two in Maryland to acquire and serve new business customers. CTC's announcement today represents a major commitment to both the Philadelphia and Baltimore areas and their surrounding communities. By activating its ATM+IP integrated communications network in these markets, the Company will now be able to deliver broadband voice and data services to business customers from Philadelphia to Allentown, PA and into Southern New Jersey markets, including Princeton and Trenton. In the Baltimore, MD marketplace, CTC will service Washington D.C. as well as the greater Baltimore area. The Company now enjoys contiguous sales and network coverage from Maine to Maryland.

In a related matter, CTC also announced the addition of Steven Cundall as Vice President of Branch Development. Mr. Cundall joins CTC with over 17 years experience in recruitment and development of sales and service teams in the field of telecommunications. Prior to joining CTC, Mr. Cundall operated Cornerstone Group, which provided consulting services to telecommunications and other businesses in both sales and organizational development. Mr. Cundall will be responsible for supporting CTC's rapid expansion plans in the company wide hiring and development of sales and service personnel.

"We are very excited about both of these announcements today" stated Robert Fabbricatore, Chairman and CEO of CTC. "The response to IntelliNET(SM) has been great and by activating our network in Philadelphia and Baltimore we now have access to business customers from Maine to Washington D.C. that spend over $25 billion on telecommunications services and over $16 billion in our medium to larger business target market." Mr. Fabbricatore continued, "The addition of Steve Cundall will permit us to open and staff branch sales offices more efficiently and make them productive more rapidly. His expertise in hiring experienced and qualified individuals is exceptional and a critical skill set in this tight job market. He is on track in meeting our sales and service staffing needs as we aggressively expand our market presence and execute our growth plan."
