Tekelec Names Ron de Lange as President and Chief Executive Officer

MORRISVILLE, NC--(Marketwire - May 31, 2011) - Tekelec (NASDAQ: TKLC), the mobile broadband solutions company, has appointed Ron de Lange as president and chief executive officer (CEO). He replaces Krish Prabhu, Tekelec's interim CEO and a Board member, who will step down from his Board seat as planned. Mr. de Lange has also been appointed to the company's Board of Directors.

Ron de Lange joined Tekelec in July 2005 as president and general manager for the Network Signaling Group and was promoted to executive vice president Global Product Solutions in 2007. As the primary architect of the company's product strategy, Ron has a keen understanding of service provider networks and their challenges, and serves on key industry technical committees. Prior to Tekelec, Ron spent 24 years at Lucent Technologies, where he held a number of leadership roles. He directed next-generation strategy, devising cross-functional convergence solutions and has managed multiple functions, including sales, marketing, manufacturing and finance.

"Ron has successfully led Tekelec's product strategy and transformation, from establishing global leadership in signaling for fixed and wireless voice networks, to addressing network intelligence problems associated with mobile data and video," said Mr. Prabhu, Tekelec's interim CEO.

"I look forward to working closely with Ron to achieve our goal of delivering substantial shareholder value from the success of our current and next generation products," said Hubert de Pesquidoux, chairman of the Board of Directors. "I also wish to thank Krish for his leadership during his interim role."

"I am excited to serve Tekelec's employees, customers, and shareholders in my new role," said Mr. de Lange, president and chief executive officer. "I believe the worldwide explosion in usage of wireless devices presents us with an excellent opportunity to work closely with our customers in accelerating their time to market for new services and grow our market share."
