SUNNYVALE, Calif.--(BUSINESS WIRE)--Oct. 24, 2001

Harmonic Inc. (Nasdaq:HLIT) announced today that David R. Van Valkenburg, Chairman of Balfour Associates, has been named to the Company's Board of Directors. For nearly 30 years, Van Valkenburg has been an innovator in broadband, telecommunications, and Internet access markets around the world.

Van Valkenburg has held top leadership and key executive positions at trend-setting cable and communications service providers in the United States and Europe. His past experience includes: Chief Executive Officer for Telewest Communications, a leading broadband communications and media company in the U.K.; Executive Vice President of MediaOne Group, Inc. located in Colorado; President of Multivision Cable TV Corp, headquartered in Greenwich, Connecticut; and President of Cox Cable Communications, Inc. based in Atlanta, Georgia. Van Valkenburg is currently on the board of directors of several public and private companies -- such as MDSI of British Columbia, Canada -- in addition to his current role as Chairman of Balfour Associates.

"The convergence of the video, telephony, and Internet services is driving a new generation of service providers and service packages for both businesses and consumers. David is a true industry pioneer and visionary who has been instrumental in evolving the industry far beyond its traditional entertainment focus," said Anthony Ley, Chairman, President, and Chief Executive Officer of Harmonic. "We look forward to the benefit of his experience, knowledge, and counsel as Harmonic expands into new market segments and geographies."

The Harvard University-educated Van Valkenburg was honored as a Member of the Cable TV Pioneers.
