NTP AGREE TO RESOLVE LITIGATION </FONT></H1>

<!-- MARKER FORMAT-SHEET="Para Flush" FSL="Default" -->
<P><FONT FACE="Times New Roman, Times, Serif" SIZE=3><I>Waterloo, Canada</I> &#150;
Research In Motion Limited (RIM) (NASDAQ: RIMM; TSX: RIM) and NTP, Inc. (NTP) today
announced that they have signed a binding term sheet that resolves all current litigation
between them.&nbsp; As part of the resolution, NTP will grant RIM and its customers an
unfettered right to continue its BlackBerry-related wireless business without further
interference from NTP or its patents.&nbsp; NTP and RIM will be finalizing the terms of
this resolution in a definitive licensing and settlement agreement in upcoming weeks. </FONT></P>

<!-- MARKER FORMAT-SHEET="Para Flush" FSL="Default" -->
<P><FONT FACE="Times New Roman, Times, Serif" SIZE=3>This resolution relates to all NTP
patents involved in the current litigation as well as all current and future NTP
patents.&nbsp; The resolution covers all of RIM&#146;s past and future products, services
and technologies and also covers all customers and providers of RIM products and services,
including wireless carriers, distributors, suppliers and ISV partners.&nbsp; Under the
terms of the resolution, RIM will have the right to grant sublicenses under the NTP
patents to anyone for products or services that interface, interact or combine with
RIM&#146;s products, services or infrastructure.&nbsp; The resolution permits RIM and its
partners to sell its products, services and infrastructure completely free and clear of
any claim by NTP, including any claims that NTP may have against wireless carriers, ISV
partners or against third party products that use RIM&#146;s BlackBerry Connect /
BlackBerry Built-In technology. </FONT></P>

<!-- MARKER FORMAT-SHEET="Para Flush" FSL="Default" -->
<P><FONT FACE="Times New Roman, Times, Serif" SIZE=3>RIM will pay to NTP US$450 million in
final and full settlement of all claims to date against RIM, as well as for a perpetual,
fully-paid up license going forward.&nbsp; The amount relates primarily to settlement of
past damages, and includes the judgment and money escrowed to date totalling US$137
million (the US$152 million previously accrued included approximately US$15 million in
other litigation related fees).&nbsp; It is expected that a substantial portion of the
US$313 million, which is the balance of the settlement amount, will be expensed in the
fourth quarter, ended February 26, 2005. </FONT></P>

<!-- MARKER FORMAT-SHEET="Para Flush" FSL="Default" -->
<P><FONT FACE="Times New Roman, Times, Serif" SIZE=3>Further comment and details will not
be disclosed at this time.&nbsp; Additional details will be provided on RIM&#146;s Q4
results conference call scheduled for April 5, 2005, pending the completion of the
definitive licensing and settlement agreement.&nbsp; </FONT></P>
