RIM and JP Mobile Team to Wirelessly Extend Enterprise Applications With Two-Way Data Synchronization

SureWave and BlackBerry Enterprise Server Technologies to Further Support Corporate Data Applications on a Variety of Devices

Dallas and Waterloo, ON - Research In Motion (RIM) (Nasdaq: RIMM, TSX: RIM), a world leading developer of wireless enterprise solutions, and JP Mobile®, a leading provider of enterprise mobility software, today announced plans to work together to enable BlackBerry® users to securely access applications using RIM's BlackBerry Enterprise Server™ and JP Mobile's SureWave™ Enterprise Server technologies. Through this relationship, JP Mobile and RIM intend to use the Mobile Data Service feature of BlackBerry Enterprise Server and SureWave Enterprise Server to provide full, bi-directional synchronization of enterprise data.

JP Mobile and RIM plan to initially focus on providing enterprise customers with secure, integrated, push-based, connectivity solutions using RIM's award-winning BlackBerry handhelds. The companies also plan to add future support for a variety of additional wireless devices and operating systems (OS) in conjunction with RIM's BlackBerry Connect™ licensing program. The addition of SureWave technology with the BlackBerry Connect licensing program is designed to help manufacturers ready their wireless devices for a broader range of enterprise data applications.

"BlackBerry continues to lead the industry with secure wireless connectivity solutions," said Jim Balsillie, chairman and co-CEO of RIM. "The combination of JP Mobile's SureWave technology with the BlackBerry platform will enable corporate customers to leverage and extend their existing IT investments through wireless synchronization of applications and data."

"Enterprises who already invested in BlackBerry Enterprise Server will be able to extend their existing infrastructure to sync corporate data applications on a variety devices," said Dayakar Puskoor, CEO of JP Mobile. "We are working with RIM to provide enterprises with a win-win situation."

JP Mobile will demonstrate the SureWave solution this week (May 6-7, 2003) at the Wireless Enterprise Symposium (www.wirelessenterprisesymposium.com) in New Orleans, LA. Visit JP Mobile at booth #B32.

The BlackBerry Connect licensing program enables mobile device manufacturers to equip their handsets with the integrated ability to connect to BlackBerry Enterprise Server using the same secure, push-based BlackBerry architecture and infrastructure that has been approved and adopted by dozens of carriers and thousands of companies and government organizations around the world.
