<P><FONT FACE="Times New Roman, Times, Serif" SIZE=2><B>Waterloo, ON</B> &#150; Research
In Motion (RIM) (Nasdaq: RIMM: TSX: RIM) today announced that more than three million
subscribers are now using the award-winning BlackBerry&reg; wireless platform, with one
million subscribers added in less than six months. This milestone demonstrates the rapidly
growing popularity of BlackBerry and follows another six months of intense activity with
RIM and its partners, including various new product introductions and many initiatives
with new and existing carriers, licensees, ISV&#146;s and other partners around the world.
With more than three million active BlackBerry subscribers worldwide, BlackBerry continues
to lead the industry. </FONT></P>

<!-- MARKER FORMAT-SHEET="Para Flush" FSL="Default" -->
<P><FONT FACE="Times New Roman, Times, Serif" SIZE=2>&#147;It&#146;s an exciting time as
BlackBerry continues to enjoy enormous success and rapid growth around the world,&#148;
said Jim Balsillie, Chairman and Co-CEO, Research In Motion. &#147;With over 50,000 retail
points of presence, accelerated geographic expansion and the anticipated addition of 100
new carriers in 2005, we are scaling our operations for the five million and 10 million
subscriber milestones.&#148; BlackBerry subscribers reached the one million mark in
February 2004 and doubled in less than ten months, reaching two million subscribers in
November 2004. The surge to three million subscribers demonstrates the continuing momentum
and expanding market opportunity for RIM and its partners. For corporate customers,
BlackBerry Enterprise Server&#153; software tightly integrates with Microsoft&reg;
Exchange, IBM&reg; Lotus&reg; Domino&#153; and Novell GroupWise&reg; and works with
existing enterprise systems to enable secure, push-based, wireless access to e-mail and
other corporate data.&nbsp; For individuals and smaller businesses, BlackBerry Internet
Service&#153; allows users to access up to ten corporate and/or personal e-mail accounts
(including Microsoft Exchange, IBM Lotus Domino and many popular ISP email accounts) from
a single device. This milestone is consistent with RIM&#146;s previous guidance for Q1
subscriber additions of 560,000-590,000 that RIM provided in its press release dated April
5, 2005. RIM&#146;s first quarter for fiscal year 2006 ends May 28, 2005 and results will
be reported June 29, 2005. </FONT></P>
