Yahoo! and Research In Motion Announce Worldwide
Relationship to Bring Yahoo! Services to BlackBerry

SUNNYVALE, CALIFORNIA and WATERLOO, ONTARIO--(CCNMatthews - March 14,

The Yahoo! Messenger service on the BlackBerry platform will allow
consumers to see which friends are online, send and receive instant
messages, have multiple conversations at once, participate in online
conferences and even send and view emoticons. Yahoo! Messenger will
leverage the BlackBerry "push" technology to deliver a premier instant
messaging experience for mobile users.

"We are excited to extend the Yahoo! experience to millions of
BlackBerry users around the world," said Doug Garland, senior vice
president, Yahoo! Mobile. "Yahoo! has become an essential part of the
lives of millions of its users and by bringing the services they love to
these great mobile devices we are making it easier for people to
communicate however they want, anywhere, anytime."

"BlackBerry provides optimized messaging capabilities with its popular
keyboards, large screens, intuitive navigation and push-based
connectivity," said Mark Guibert, Vice President, Corporate Marketing at
Research In Motion. "Through our relationship with Yahoo!, BlackBerry
users will enjoy another powerful communications option to keep them
connected while away from their desk."
