BlackBerry Ranks #1 With Legal Industry

Over 85% of AmLaw 100 and 70% of AmLaw 200 Use BlackBerry to Stay Connected and Productive

Waterloo, ON - Research In Motion (RIM) (Nasdaq: RIMM; TSX: RIM) today revealed that over 85% of AmLaw* 100 and 70% of AmLaw 200 law firms have selected BlackBerry® to help stay productive through secure, push-based, always-on, wireless connectivity. BlackBerry provides a complete wireless solution for managing email, phone, corporate data, SMS (Short Message Service), web browser and organizer applications. Many firms have also gone beyond the built-in wireless data applications by working with RIM's software development community to wirelessly enable additional applications such as time and billing management, CRM (Customer Relationship Management), case management, document management and research tools.

BlackBerry has proven to be popular with both users and IT departments. According to a recent survey (conducted by LawNet, Inc.) of IT professionals in law firms with more than 200 attorneys, BlackBerry is the "most popular technology purchased over the last three years" and (for the third year in a row) BlackBerry was also chosen as "the coolest new technology that lawyers would actually use."

"BlackBerry is a real business productivity tool. Once people start to use it, they soon find they can't live without BlackBerry. Partners saw the handhelds and immediately recognized that it would make their working lives easier," said Dave Turley, Global Manager of Back Office Systems and Electronic Messaging at Clifford Chance LLP. "Our use of BlackBerry is one of the rare instances when the introduction of technology has been driven by users. It is also the first time that the company itself has been willing to purchase wireless technology for staff, due to the obvious business benefits that BlackBerry delivers."

"Our experience with BlackBerry has been very positive. The productivity enhancements that we've gained for the attorneys and the senior professionals here have been significant. We definitely achieved those very early on in the process of getting the people the mobility, the connectivity and the accessibility that they need to continue to deliver an enhanced level of client service. The return on investment has skyrocketed," said David Gregson, Director of Information Systems, Mintz Levin.

"My BlackBerry handheld has provided me with the technology to keep in touch with the office and our clients whether or not I am in the office," says David A. Rogers, Partner, Bricker & Eckler. "It helps me stay connected and productive, truly offering a great benefit for my clients, the firm and me - personally."

"The BlackBerry wireless solution has been widely deployed in law firms because of its ability to deliver a compelling return on investment and a strong competitive edge through enhanced client service, increased productivity, improved collaboration and direct cost savings," said Mark Guibert, Vice President of Corporate Marketing at Research In Motion. "BlackBerry is available with a broad choice of handhelds and services that can meet the needs of large law firms as well as smaller boutique firms or individual lawyers."

BlackBerry is the industry-leading wireless solution that keeps mobile professionals connected to their important information and communications while on the go. It is an award-winning solution that can provide users with integrated wireless access to a range of business applications, including email, phone, corporate data, web, SMS and organizer applications. BlackBerry Enterprise Server™ software tightly integrates with Microsoft® Exchange or IBM Lotus® Domino™ and works with existing enterprise systems to enable push-based, secure access to wireless email and other corporate data. BlackBerry Web Client, an Internet-based email interface, allows users to access multiple existing corporate and/or personal email accounts from a single BlackBerry handheld.
