ICG Communications Expands Network to Serve Cincinnati; Provides Competitive Alternative for Commercial, ISP Customers.

CINCINNATI--(BUSINESS WIRE)--April 12, 1999--

Company switch site has historical significance

as location of first Ohio telephone exchange

At the same location where telephone service began more than 120 years ago in Ohio, competitive local telecommunications provider ICG Communications, Inc. (NASDAQ: ICGX) announced today it has placed in service network switching equipment for Cincinnati and surrounding communities.

ICG, based in Englewood, Colo., has activated a Lucent 5ESS(R) switch at its facility at Fourth and Walnut streets in downtown Cincinnati. The enhanced switch provides data networking capabilities to the circuit-switched network. ICG also is installing a synchronous optical network (SONET) that will link with other markets in the Ohio Valley.

Customers in the greater Cincinnati region will be able to take advantage of ICG's suite of bundled services for the commercial and the Internet service provider (ISP) business segments. These services include local, long distance and enhanced telephony, data communications, Digital Subscriber Line and network management for ISPs.

The original Cincinnati telephone exchange - the first in Ohio and tenth in the nation - went into service on Sept. 1, 1878, on the same city block where ICG now operates its equipment.

"The location of our switch site is historically significant to the development of telecommunications in Ohio. We intend to build on this tradition by ushering in a new era of commercial local telephone and ISP service, an era that will give Cincinnati consumers competitive alternatives," said John Humphries, ICG's regional president. Humphries noted that the Cincinnati market has more than a quarter million business access lines, with an emphasis on the retail, manufacturing and health care industries. He added that ICG plans to compete aggressively for market share in Cincinnati as it has in other Ohio cities. ICG also operates local switches and SONET networks in Akron, Cleveland, Columbus and Dayton.

ICG's presence in Cincinnati also will help further develop the city's information highway infrastructure, and will create additional employment opportunities for telecommunications employees in the market, Humphries said.
