KASTEN CHASE AND RESEARCH IN MOTION TO PROVIDE BLACKBERRY WIRELESS EMAIL SOLUTION FOR U.S. GOVERNMENT'S DEFENSE MESSAGE SYSTEM STERLING, VIRGINIA February 8, 2001 - Kasten Chase (TSE:KCA), a leading provider of high-assurance data security systems, and Research In Motion Limited (RIM) (Nasdaq: RIMM; TSE: RIM), a world leader in the mobile communications market, today announced an agreement focused on providing secure wireless access to the U.S. Government's Defense Message System (DMS) via RIM's BlackBerry(tm) wireless email solution. Kasten Chase will integrate its RASP Data Security(tm) for wireless applications and message handling software with RIM's award-winning BlackBerry(tm) wireless email solution to provide secure 'Always On, Always Connected.' access to DMS. The integrated solution will be designed to meet government standards for remote access to DMS. Under the terms of the agreement, Kasten Chase will also market the solution to government end-user organizations and select BlackBerry government resellers. "We are very pleased to be working with RIM to introduce, for the first time, secure wireless access to the DMS application," said Paul Hyde, Chief Executive Officer at Kasten Chase. "Our RASP Data Security and message handling software integrated with RIM's popular BlackBerry wireless email solution is a very compelling proposition for the existing 300,000 plus DMS users within the U.S. Department of Defense [DoD] and allied countries." "BlackBerry incorporates a fundamentally sound security model that enables end-to-end encryption. This end-to-end design is crucial for meeting the security standards of most organizations," said Don Morrison, Chief Operating Officer at Research In Motion. "End-to-end, Triple DES encryption technology is a key component and a contributing success factor of the BlackBerry solution for Microsoft Exchange and Lotus Domino environments. Similarly, the Kasten Chase RASP Data Security solution for wireless communications will provide the approved encryption technology and enhanced security features necessary for DMS environments." BlackBerry is an end-to-end wireless email solution designed to allow mobile users access to their email wherever they go. BlackBerry features an integrated package that includes the industry's most advanced wireless handhelds, innovative software and nationwide airtime on leading wireless data networks. DMS is a global messaging system for military and intelligence communities. The system was initially designed for use by the allied countries and has been implemented by governments in the United States, Great Britain and Canada. Within the U.S. Department of Defense (DoD), the Defense Information System Agency (DISA), began implementing DMS in 1988. DISA's objective is to provide some 2,000,000 defense personnel around the globe with DMS services based on commercial products such as BlackBerry with RASP Data Security and RASP Secure Access. BlackBerry with RASP Data Security will offer a complete, secure wireless solution for DMS, providing authentication of sender and receiver, end-to-end confidentiality, integrity of message content, and non-repudiation. It will be fully compatible with global DMS desktop systems. The integrated BlackBerry and RASP solution is scheduled to be available from Kasten Chase later this year.
