RIM and mmO2 Expand European Agreement for BlackBerry

mmO2 to Offer BlackBerry Roaming Across the UK, The Netherlands, Ireland and Germany

Waterloo, ON - Research In Motion Limited (RIM) (Nasdaq: RIMM; TSE: RIM), a world leader in the mobile communications market, today announced it is extending its UK agreement signed last year with mmO2 (formerly part of British Telecommunications) to supply the BlackBerry™ wireless email solution throughout mmO2's European operating businesses.

BlackBerry is now commercially available in Europe in the UK, the Netherlands and Ireland. BlackBerry user trials are also underway in Germany. As a result of the latest agreement, corporate users will be able to immediately benefit from full roaming capabilities across the mmO2 footprint. During 2002, this roaming capability is expected to extend to other European territories where GPRS (2.5G) services can be accessed.

Peter Erskine, chief executive officer of mmO2 , commented: "BlackBerry has been highly successful in North America and is a long-awaited mobile data application for our European customer-base. The initial response in the UK has been extremely encouraging. There has been 100% take-up on trials and, in just three months since the solution was launched into the market, we have signed up over 100 corporate customers. The extension of our partnership with RIM to include all of our operations is a key illustration of the strength the mmO2 group brings through its ability to work together and reflects its leading position in the provision of mobile data to the business market."

Charles Meyer, director and vice president, RIM Europe, said: "We are pleased to extend the BlackBerry experience to Germany, the Netherlands and the Republic of Ireland through our partnership with the mmO2 group. Together, we have demonstrated the power and reliability of BlackBerry in the UK, and we will build on that success to further the status of BlackBerry as the premier wireless solution for corporate data. Through this agreement, we have substantially increased our distribution and market opportunity."

BlackBerry is the leading wireless email solution for mobile professionals. It is the only completely integrated package that includes software, airtime and wireless handhelds to provide easy access to email while on the go. mmO2 is the first to market a solution of this calibre in its four European territories.
