<P><FONT FACE="Times New Roman, Times, Serif" SIZE=2><B>WATERLOO, ON &#150; </B>Research
In Motion (RIM) (Nasdaq: RIMM; TSX: RIM) today announced the immediate availability of
BlackBerry&reg; Enterprise Server Express&#153;, a new offering aimed at small and
medium-sized businesses, branch offices and companies new to BlackBerry. BlackBerry
Enterprise Server Express provides the same enterprise-level security, reliability,
features and functionality of BlackBerry Enterprise Server v4.1 and is available as a free
download from RIM via the Internet to any customer who purchases a new BlackBerry device.* </FONT></P>

<!-- MARKER FORMAT-SHEET="Para Flush" FSL="Default" -->
<P><FONT FACE="Times New Roman, Times, Serif" SIZE=2>&#147;Mobile access is an
increasingly essential requirement of doing business and this is especially prevalent in
smaller businesses,&#148; said Mike Lazaridis, President and Co-CEO at RIM.
&#147;BlackBerry Enterprise Server is renowned for helping companies become more
productive and responsive, while providing industry-leading security, functionality,
manageability, and back-end integration. With BlackBerry Enterprise Server Express,
we&#146;re now making it easier than ever for new customers to derive the full benefits of
the BlackBerry solution.&#148; </FONT></P>

<!-- MARKER FORMAT-SHEET="Para Flush" FSL="Default" -->
<P><FONT FACE="Times New Roman, Times, Serif" SIZE=2>BlackBerry Enterprise Server Express
provides tight integration with Microsoft&reg; Exchange, IBM&reg; Lotus&reg; Domino&reg;
or Novell&reg; GroupWise&reg; to enable secure, pushed-based wireless access to email,
organizer, Internet and intranet applications. BlackBerry Enterprise Server Express
software comes with a single user license and is upgradeable to support up to 15 users
(with purchase of additional client access licenses). It can also be upgraded beyond 15
users (with the purchase of an electronic unlock key) to a full BlackBerry Enterprise
Server. </FONT></P>
