PalmSource and RIM to Extend BlackBerry Wireless Email and Data Connectivity Solution for Palm Powered Devices

PALMSOURCE DEVELOPERS SEMINAR, San Mateo, CA - May 6, 2003 - PalmSource, Inc., provider of the world's most popular operating system for handhelds and smartphones, and the Palm OS® subsidiary of Palm, Inc. (Nasdaq: PALM), and Research In Motion (RIM) (Nasdaq: RIMM; TSX: RIM), the leading developer of wireless enterprise solutions, today announced they will work together to market and promote the BlackBerry Connect™ solution to Palm OS licensees to enable secure, push-based email and data connectivity for wireless Palm Powered™ handhelds and smartphones.

As the enterprise becomes increasingly mobile, demand for easily deployable, wireless solutions that immediately increase productivity and reduce IT costs continue to grow. Mobile professionals and IT departments require reliable and secure access to corporate data from their wireless device and the ease of integration with existing back-end resources. Through RIM's BlackBerry Connect licensing program, Palm OS licensees will be offered RIM's software solution for Palm Powered handhelds and smartphones, that will enable behind-the-firewall, enterprise-ready BlackBerry® email and corporate data connectivity.

"The BlackBerry connectivity architecture and infrastructure has been certified by leading wireless carriers around the world and BlackBerry Enterprise Server™ has been deployed in more than ten thousand companies and government organizations," said Mike Lazaridis, president and co-CEO at Research In Motion. "Together with PalmSource, we will enable carriers and customers to leverage their existing investments and deliver the BlackBerry wireless experience to new users of Palm Powered wireless devices."

"We are pleased to partner with RIM to deliver an industry-leading robust, secure wireless email and corporate data solution for Palm Powered mobile devices," said David Nagel, president and chief executive officer for PalmSource. "BlackBerry Connect for Palm Powered devices will widen the choices of wireless messaging solutions for Palm OS licensees in order to better meet the needs of our enterprise customers."

BlackBerry Connect on Palm OS will deliver a powerful combination for Palm Powered mobile devices to execute on enterprise customer requirements for enhanced flexibility, security and manageability, uncompromised power and ease of use, and low training, support and maintenance costs. Palm OS has achieved a leading position in the enterprise because it offers a low total cost of ownership (TCO), while also supporting the largest base of mobile software worldwide1.

BlackBerry is a leading wireless enterprise platform that has been widely deployed to provide mobile access to information. BlackBerry Enterprise Server supports both Microsoft® Exchange and IBM Lotus® Domino™ environments with single mailbox integration and provides IT departments with centralized administration, end-to-end security (using Triple DES encryption), multi-network support and a powerful development platform. RIM's BlackBerry Connect licensing program enables mobile device manufacturers to equip their handsets with the same reliable, secure and push-based BlackBerry wireless data experience.

Further details regarding the agreement have not been disclosed at this time.
