MILPITAS, Calif.--(BUSINESS WIRE)--Feb. 15, 1999--

Leading Cable Modem Supplier in Europe Extends Reach to

Strengthen Leading Market Position Throughout Europe

Com21, Inc., (Nasdaq:CMTO), the No.1 ranked cable modem supplier in Europe, based on an independent market study by U.S.-based RHK, today announced the opening of its main European office in Rotterdam, The Netherlands.

Com21 also maintains a sales office in Berlin, Germany.

A number of recent new business wins -- including Spain's Cable i Televisio de Catalunya, in Barcelona, Spain -- are helping Com21 bring high-speed access to the Internet to customers across Europe. Com21 is also working with such leading companies as Eneco, United Telekabel Holding (a UPC company), and France Telecom.

Com21 launched its European operations in early 1996 and sells through a network of system integrators throughout Europe including: Philips Broadband Networks, Eindhoven, The Netherlands, Siemens A.G., Munich, Germany and Fringes Networking Services, Valencia, Spain.

Since that time, the company has seen its European market share grow to over 4 million HHP (households passed).

With its European staff now extending the company's reach into all major markets in Europe, such as France, The Netherlands, Denmark, Switzerland, Sweden, Spain and Eastern Europe, Com21 is positioned to continue building on the excellent progress it has made to date.

"The opening of our sales and support operations in Europe is an exciting step for Com21 in what represents a crucial marketplace for us," said Pete Fenner, president and CEO of Com21. "Industry analysts are projecting the European cable modem market to grow in excess of 100 percent per year, and Com21 is determined to help drive the market forward with superior products and service."

"Already number one in Europe, and with full ISO 9001 'Registered Firm' status, Com21 is committed to even further improving our business processes and the quality of our support to the benefit of our European customers," Pete Fenner said.

Com21 is rapidly growing its worldwide market share with the total number of homes passed now reaching 9.2 million HHP.
