Tekelec Growth Drives Organizational Changes; Headquarters to transition from Calabasas, Calif., to Morrisville, N.C.

CALABASAS, Calif. -- Tekelec (NASDAQ:TKLC), a leading developer of telecommunications products for next-generation fixed, mobile, digital and packet networks, today announced that it is adding key resources to its top corporate management structure.

"During the past year, our company's revenue grew more than 50 percent, we greatly expanded our global business and we completed several major acquisitions that increased our capabilities to provide integrated communications solutions for our customers on a global basis," said Fred Lax, president and CEO of Tekelec. "Similarly, we're now strengthening our strategic management and operational infrastructure as we concentrate on further expanding as a global, market-focused solutions company."

In order to increase senior executive focus to customers and the rapidly growing market opportunities for Tekelec's advanced signaling, switching and communications software solutions, Lori Craven has been appointed as executive vice president, Global Sales & Marketing and Customer Service. In addition, Rick Mace, current president and general manager of Tekelec's Communications Software Solutions Group (CSSG), is appointed executive vice president, Global Business Group Operations, also in Morrisville, NC. Mace will be focusing on the day-to-day operations of Tekelec's business groups, including manufacturing operations, that comprise Tekelec's diversified telecommunications business. Further, also coming to North Carolina from his former role leading Tekelec's French operations will be Eric Gehl, succeeding Mace as president and general manager of CSSG.

"I'm very pleased with the expanded leadership team," added Lax. "We are making the strategic decisions that give us the scale, flexibility and resources needed to sustain our global growth and success. As part of that process, we've also decided to transition Tekelec's headquarters to our North Carolina location to allow for better alignment and coordination with Tekelec's core operating groups."

The transition of Tekelec's headquarters will occur in stages over the next year as it vacates the current facility in Calabasas, Calif. where as many as 145 people had recently been employed. Over the past year, the number of Calabasas-based employees has been reduced to about 40 people as Tekelec closely aligned its manufacturing operations with its business units and expanded the use of contract manufacturing. The additional realignment will provide a significant opportunity to further improve Tekelec's operations by fully integrating the California-based finance, accounting and IT functions into the business units they support.
