Research In Motion and Glenayre Announce Alliance for New Solutions, and Settlement of Patent and Trademark Infringement Litigation

Companies Agree to Integrate Unified Communications Solution with BlackBerry

Waterloo, Canada and Atlanta, Georgia - February 5, 2002 - Research In Motion Limited (RIM) (Nasdaq: RIMM; TSE: RIM), a world leader in the mobile communications market, and Glenayre Electronics, Inc. (Nasdaq: GEMS), a leading global provider of advanced and next-generation messaging solutions, today announced that the companies are working together to integrate Glenayre's messaging services with RIM's BlackBerry Wireless Handheld™. This collaboration will create a carrier-grade offering that will provide seamless integration of voice mail, e-mail, fax, and text messages on a single device.

"BlackBerry is built on an extensible Java-based architecture that allows RIM to partner with other leading technology companies to continuously expand the BlackBerry value proposition," said Mike Lazaridis, President and Co-CEO at Research In Motion. "Our development effort with Glenayre is designed to expand our carrier partners' service offering and deliver another compelling mobile application for BlackBerry users."

"Glenayre is excited by the opportunities this alliance presents," said Eric Doggett, President and Chief Executive Officer for Glenayre. "We are focused on using technology as a tool to simplify communications. Together with RIM, our unified communications solutions will make it easier for subscribers to stay in touch by increasing the degree of control over when, where and how they communicate, while reducing the number of devices they need to purchase and carry. By leveraging RIM's impressive secure enterprise reach and expertise with Glenayre's carrier-grade unified communications solutions, we believe our joint offering will be both highly differentiating and compelling for service providers and users."

Based on the initial collaboration, a technology demonstration is planned for Glenayre's stand #B31 during the GSM World Congress tradeshow from February 19-22, 2002 in Cannes, France. The technology demonstration will illustrate how subscribers will be able to manage, receive and listen to voice messages using BlackBerry handhelds.

The companies also announced they have reached a settlement of the patent and trademark infringement complaint filed by RIM in May 2001. Under the terms of the agreement, both parties acknowledge that RIM's Single Mailbox Integration Patent (United States Patent No. 6,219,694) is valid and both parties agree to dismiss all pending claims. Further details of the settlement were not disclosed. Glenayre's suit filed in July 1999 has also been resolved.
