NAVASTREAM AND GSMK PARTNER TO BRING ENCRYPTED CELL PHONE TO THE UNITED STATES

San Francisco California, Frankfurt Germany, Berlin Germany -- February 18th, 2005

Navastream, a world leader in managed security services, and GSMK mbH, Germany's top mobile encryption manufacturer, today announced a strategic partnership to bring the CryptoPhoneTM 200 and other new encrypted mobile phones to the U.S. market. Under the terms of the agreement, Navastream will distribute GSMK devices in the U.S., and the companies will work together to serve the security needs of top executive teams around the world.

The CryptoPhone is the new standard in encrypted mobile communication devices. GSMK's CryptoPhone technology is based on the strongest encryption and voice processing algorithms in the industry (AES and Twofish with 256 bit effective keylength). CryptoPhone users can travel the world knowing that their conversations are secure, no matter which country or what network they are using.

The CryptoPhone will strengthen Navastream's core offering, the Imperial Cipher Suite, which is a complete encryption solution for top-executive teams, delivering AES-based 256-bit encryption on all forms of communications, including voice, audio, video and data. The Imperial Cipher Suite enables its customers to dramatically reduce their exposure to industrial espionage, theft and sabotage.

"We are excited to work with Navastream, the leading communications security vendor, to address the emerging customer requirement for true end-to-send security solutions across a variety of platforms," said Bjoern Rupp, CEO of GSMK. "Their knowledge and experience providing robust security solutions for executive communication makes them the ideal partner for this next stage in secure communications."

"The rapid expansion of mobile voice and data communications combined with Internet-enabled cell phones have blurred the lines of traditional telecommunications, posing new security risks," said Altura Ewers, CEO of Navastream. "A major mobile communications network was compromised recently, which led to a breach of their clients' email and a massive spate of fraudulent activity. These new risk exposures mean voice, video, email, and mobile communications now require the same level of advanced security. By adding GSMK CryptoPhone devices to Navastream's offerings, we.re further closing the security loop for executives."

The Navastream-GSMK partnership is the result of ongoing efforts of both companies to expand their security offerings to include the latest means of communication. Navastream will release new products, fortified by encryption technology from GSMK, to head off an array of new and rapidly expanding security risks.
