1.       Name and Address of Company

         Research In Motion Limited (the "Company" or "RIM")
         295 Phillip Street
         Waterloo, Ontario
         N2L 3W8

2.       Date of Material Change

         October 7, 2005.

3.       News Release

         A news release was issued in Waterloo, Ontario on October 7, 2005
         through the newswire services of CCN Matthews and BusinessWire, and
         is annexed hereto as Schedule "A".

4.       Summary of Material Change

         RIM announced that the U.S. Court of Appeals for the Federal Circuit
         ("Federal Circuit") issued a ruling on October 7, 2005 in the patent
         litigation between RIM and NTP, Inc. ("NTP"). The Federal Circuit
         denied RIM's petition to rehear the three-judge panel decision that
         was issued in this case on August 2, 2005.

5.       Full Description of Material Change

         RIM announced that the Federal Circuit issued a ruling on October 7,
         2005 in the patent litigation between RIM and NTP. The Federal Circuit
         denied RIM's petition to rehear the three-judge panel decision that
         was issued in this case on August 2, 2005.

         The August 2, 2005 three-judge panel decision would reverse the
         District Court's ruling of infringement on 6 of the 16 claims, and
         would find that RIM does not infringe those 6 claims. That decision
         would also vacate the District Court's finding of infringement of an
         additional 3 of the 16 patent claims asserted against RIM in this
         case, because the District Court erred in construing their scope, and
         would remand to the District Court for further proceedings based on
         the new claim construction. The decision would affirm infringement of
         the remaining 7 claims of the NTP patents. But the decision would
         vacate the damages award and injunction originally entered by the
         District Court, and would remand the case for further proceedings.

         All of the NTP patent claims have now been rejected by the U.S. Patent
         and Trademark Office ("Patent Office") in its initial rulings in
         reexamination proceedings, based in part on prior art not considered
         in the District Court trial in 2002.

         The Federal Circuit's ruling on October 7, 2005 lets stand the
         three-judge panel decision of August 2, 2005. RIM now plans to seek
         review of that decision by the U.S. Supreme Court. While en banc
         review at the Federal Circuit or further review by the Supreme Court
         is generally uncommon, RIM continues to believe this case raises
         significant national and international issues warranting further
         appellate review. On October 13, 2005, RIM filed a motion asking the
         Federal Circuit to stay further proceedings in the case until the

<PAGE>

         Supreme Court decides whether it wants to review the critical issues
         presented by the Federal Circuit's decision. If the patent dispute
         returns to the District Court on remand proceedings, RIM expects the
         District Court will decide all matters relating to enforcement of the
         settlement agreement announced by the parties on March 16, 2005, as
         well as the impact of the Patent Office re-examinations of the NTP
         patents on the litigation proceedings. RIM expects that NTP will ask
         the court to enter an injunction prohibiting RIM from providing
         BlackBerry service and from using, selling, manufacturing or importing
         its handhelds and software in the United States. While RIM maintains
         that an injunction is inappropriate given the facts of the case and
         substantial doubts raised subsequent to trial as to the validity of
         the patents in question, it ultimately will be up to the Courts to
         decide these matters and there can never be an assurance of a
         favorable outcome in any litigation. If a further injunction is
         granted to NTP and RIM is not able to promptly vacate, stay or
         overturn the injunction, provide services or products outside the
         scope of the NTP patents, or conclude a license with NTP on reasonable
         terms: (a) RIM may be unable to continue to export or make available
         for sale its wireless handhelds and software into the United States
         and/or make available BlackBerry service to users in the United
         States, which is the largest market for RIM's products and services;
         and (b) the Company may have to terminate the contractual arrangements
         with its customers, carriers and resellers in the United States, and
         the Company could be subject to claims for any losses incurred or
         claims against such customers, carriers and resellers.

6.       Reliance on subsection 7.1(2) or (3) of National Instrument 51-102

         Not applicable.

7.       Omitted Information

         No significant facts have been omitted from this report.

8.       Executive Officer

         For further information, please contact Dennis Kavelman - Chief
         Financial Officer of the Company at (519) 888-7465.

9.       Date of Report

         Dated at Waterloo, Ontario, this 17th day of October, 2005.

FOR IMMEDIATE RELEASE

RIM Provides Update on NTP Litigation


Waterloo, ON - The U.S. Court of Appeals for the Federal Circuit ("Federal
Circuit") issued a ruling today in the patent litigation between Research In
Motion Limited ("RIM") (Nasdaq: RIMM; TSX: RIM) and NTP, Inc. ("NTP"). The
Federal Circuit denied RIM's petition to rehear the three-judge panel decision
that was issued in this case on August 2, 2005.

That three-judge panel decision would reverse the District Court's ruling of
infringement on 6 of the 16 claims, and would find that RIM does not infringe
those 6 claims. That decision would also vacate the District Court's finding of
infringement of an additional 3 of the 16 patent claims asserted against RIM in
this case, because the District Court erred in construing their scope, and
would remand to the District Court for further proceedings based on the new
claim construction. The decision would affirm infringement of the remaining 7
claims of the NTP patents. But the decision would vacate the damages award and
injunction originally entered by the District Court, and would remand the case
for further proceedings.

All of the NTP patent claims have now been rejected by the U.S. Patent and
Trademark Office ("Patent Office") in its initial rulings in reexamination
proceedings, based in part on prior art not considered in the District Court
trial in 2002.

The Federal Circuit's ruling today lets stand the three-judge panel decision of
August 2, 2005. RIM now plans to seek review of that decision by the U.S.
Supreme Court. While en banc review at the Federal Circuit or further review by
the Supreme Court is generally uncommon, RIM continues to believe this case

appellate review. RIM will ask the Federal Circuit to stay further proceedings
in the case until the Supreme Court decides whether it wants to review the
critical issues presented by the Federal Circuit's decision. If the patent
dispute returns to the District Court on remand proceedings, RIM expects the
District Court will decide all matters relating to enforcement of the

impact of the Patent Office re-examinations of the NTP patents on the
litigation proceedings. RIM expects that NTP will ask the court to enter an
