Richardson, Texas, June 14, 2005 — The Board of Directors of Sipera Systems Inc is pleased to announce the immediate appointment of Seshu Madhavapeddy as the company's President and Chief Executive Officer. Sipera Systems delivers comprehensive security systems for protection of session based real-time IP applications such as VoIP, Video & Multimedia.

We are delighted to have been able to recruit someone of Seshu's caliber".

"I am very excited about the market opportunity for Sipera's VoIP Security Solutions and impressed with the technology", said Seshu Madhavapeddy, Sipera's newly appointed CEO.
