RIM and Sun Microsystems Enable End-to-End Wireless Enterprise Solutions

Leading Software Developers Extend Enterprise Applications to Mobile Environments

JavaOneSM - San Francisco, CA - March 28, 2002 - Research In Motion Limited (RIM) (Nasdaq: RIMM; TSE: RIM) and Sun Microsystems, Inc. (Nasdaq: SUNW) are showcasing Java™-based wireless enterprise technologies this week at JavaOne in San Francisco. Following the introduction of the BlackBerry 5810™ (the first Java-powered wireless handheld available for 2.5G GSM/GPRS networks in North America), RIM and Sun are working together to provide the platform, products, services and tools necessary for leading enterprise software developers to extend their applications wirelessly.

"This is a compelling example of how Java technologies are helping create cutting edge solutions to provide services on the Web anywhere, anytime, using wireless devices," said Aisling MacRunnels, Director, Market Solutions, Java and XML, Sun Microsystems, Inc. "Sun is working closely with RIM to mobilize enterprise applications through the Java platform and drive the next wave of business productivity increases and the wireless value chain."

"Network carriers, device manufacturers and application developers are embracing Java as the enterprise platform of choice," said David Yach, Vice President, Software at Research In Motion. "With a standards-based J2ME™ platform and support from leading enterprise software companies such as Siebel Systems, Computer Associates, Cognos and PointBase, we are now opening BlackBerry™ beyond email to allow broader wireless integration within the enterprise."

RIM and Sun address all aspects of wireless solutions deployment from back-end systems and end-user devices to support and consulting services required by customers. Following a true end-to-end wireless strategy, RIM and Sun enable the entire development chain including: back-end technologies that drive the delivery of portal and content services; core and access network software that provides an open, carrier-grade foundation for building network infrastructure applications; mobile devices that leverage Java technology to access and run rich enterprise applications and services; and developer tools that provide an ideal environment and comprehensive resources for building wireless Java applications. The solution is then completed with integration services through Sun Professional Services that significantly ease the development and deployment of Java-based solutions through plan, design and implementation consultation; and support services that pull together all elements of the wireless strategy and also provide training, and education to customers.

RIM and Sun provide a powerful platform to enable leading software developers to extend enterprise applications wirelessly. Java technology provides an industry standard programming platform that significantly eases the development and deployment of wireless applications and RIM has implemented Java 2 Micro Edition (J2ME) as the core operating system for BlackBerry 5800 series handhelds allowing ISVs to tightly integrate their applications with BlackBerry.

Siebel Systems has certified Siebel 7, the latest version of Siebel eBusiness Applications, with BlackBerry. Companies that deploy Siebel eBusiness Applications for sales force automation or field service automation on BlackBerry can increase productivity, improve customer relationships and responsiveness and can enhance decision-making capabilities through wireless access to current corporate information.

"Siebel Systems is committed to developing mobile solutions that take full advantage of open standards platforms," said David Schmaier, Executive Vice President, Siebel Systems. "By extending the entire family of Siebel eBusiness Applications to Java-based BlackBerry handhelds, our customers can access their existing Siebel eBusiness Applications in a wireless environment and maximize the return on their investment."

Computer Associates is committed to supporting J2EE™ and J2ME in its industry-leading portfolios of infrastructure and information management solutions, including Unicenter for enterprise management, eTrust for security, BrightStor for storage, AllFusion for application life cycle management, Advantage for database management and application development, and CleverPath for portal and business intelligence.

"Our strong partnerships with RIM and Sun provide our mutual customers with powerful, standards-based resources for the development, deployment and management of multi-tier, enterprise-class eBusiness applications based on BlackBerry and Java technologies," said Jeff Gartner, CA's Vice President of Marketing for Emerging eBusiness Solutions. "We will continue to leverage each other's expertise to help customers take advantage of the significant opportunities in the mobile marketplace and to ensure that their wireless applications can be effectively managed by CA's eBusiness management solutions and those from our solution partners."

Cognos is developing mobile business intelligence solutions for BlackBerry and has included BlackBerry support for its NoticeCast application. NoticeCast provides BlackBerry users with the ability to determine business patterns and develop wireless agent alerts to better inform mobile professionals within an organization.

"RIM continues to extend the enterprise business value of BlackBerry Wireless Handhelds. Today, BlackBerry users can benefit from the powerful interplay of Cognos' robust, industry-leading business analytics and Cognos NoticeCast's unique narrowcast, push business intelligence functionality. By embracing Java-based wireless technologies, BlackBerry users will have access to even richer business information, delivered in mission-critical time frames with Cognos NoticeCast," said Patrick O'Leary, Vice President of Strategic Alliances at Cognos.

PointBase's pure Java RDBMS extends corporate data beyond the firewall out to BlackBerry Wireless Handhelds. By enabling Java developers to integrate a SQL database and bi-directional data synchronization into enterprise applications, mobile users can work with important corporate information and easily synchronize that information.

"The combined technologies of RIM and PointBase empower the mobile worker with valuable corporate information and applications on their BlackBerry handheld," said Cameron McEachern, Executive Vice President of Sales and Marketing for PointBase. "By delivering a persistent data store on BlackBerry handhelds, PointBase increases productivity and efficiency and shortens workflow processes for mobile users."
