Morrisville, NC — April 10, 2008 — Tekelec (NASDAQ: TKLC) today announced that the Company’s Board of Directors has nominated Krish Prabhu for election to the Board at the Company’s upcoming May 16 Annual Shareholders’ Meeting.

Prabhu retired as chief executive officer and president of Tellabs in February, 2008. Prior to joining Tellabs in 2004, Prabhu was a venture partner at Morgenthaler Ventures from 2001 until 2004, where he was involved with the funding and development of several communications and information technology companies. Prabhu served as chief operating officer of Alcatel Telecom from 1999-2001 and as chief executive officer of Alcatel USA from 1997 to 1999. He began his telecommunications career in 1980 at AT&T Bell Laboratories as a member of the technical staff. Among his degrees, Prabhu holds a Master of Science degree and a Ph.D. in electrical engineering from the University of Pittsburgh. He has previously served on the boards of public companies Symmetricom, Agere, ECI Telecom and Freescale.

“Krish Prabhu brings technical depth, international breadth, customer relationships and leadership experience, drawing from over twenty-five years in telecommunications,” said Mark Floyd, Chairman of the Board of Directors, Tekelec. “I believe Krish would make an excellent addition to the Tekelec Board, and the company will benefit from his substantial experience if he is elected in May.”
