News releases were issued in Waterloo, Ontario on October 21, 2005 and October 26, 2005 through the newswire services of CCN Matthews and BusinessWire, and are annexed hereto respectively as Schedules “A” and “B”.

4.	Summary of Material Change

On October 21, 2005, RIM announced that the U.S. Court of Appeals for the Federal Circuit ("Federal Circuit") had issued a ruling that day in the patent litigation between RIM and NTP, Inc. ("NTP"). The Federal Circuit denied RIM's motion to stay further proceedings in the case until the U.S. Supreme Court (“Supreme Court”) decides whether it will accept an appeal of the decision in this case.

On October 26, 2005, RIM announced that the Supreme Court issued a ruling that day in the patent litigation between RIM and NTP. The Supreme Court denied RIM's motion to stay further proceedings in the case until the Supreme Court decides whether it will accept an appeal of the decision in this case.

5.	Full Description of Material Change

On October 21, 2005, RIM announced that the Federal Circuit issued a ruling that day in the patent litigation between RIM and NTP. The Federal Circuit denied RIM's motion to stay further proceedings in the case until the Supreme Court decides whether it will accept an appeal of the decision in this case.

The Federal Circuit decision of August 2, 2005 vacated the injunction and damages award originally entered as a result of the District Court trial in 2002 and remanded the case to the District Court for further proceedings. The Federal Circuit decision also reversed or vacated the infringement finding on 9 of the 16 litigated patent claims.

The Supreme Court was not asked to, and did not decide, whether it ultimately will accept an appeal of the decision in this case. Rather, the Supreme Court merely decided that it would follow its normal course of allowing the District Court to decide whether and to what extent to continue the litigation in light of all relevant circumstances, including the prospect that the Supreme Court may decide to hear the case. The process by which the Supreme Court will decide whether to hear the case is expected to occur over the next few months. While 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.

During the upcoming proceedings, the District Court will be asked to decide a variety of matters relating to the litigation including the enforcement of the settlement agreement announced by the parties on March 16, 2005, the impact of the Patent Office re-examinations of the NTP patents on the litigation, and the further proceedings ordered by the Federal Circuit in its August 2, 2005 ruling. RIM also expects NTP to ask the District Court to enter a new injunction prohibiting RIM from providing BlackBerry service and from using, selling, manufacturing or importing its handhelds and software in the United States. RIM expects the District Court will schedule briefings or hearings prior to deciding each of these matters. 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.

The next step in the litigation is expected to be a scheduling conference between the parties and the District Court within the next few weeks to begin discussing the subject and timing of further briefings, hearings and other proceedings relating to all matters under consideration, including any potential motion for an injunction that NTP may decide to file.

No significant facts have been omitted from this report.

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 motion to stay further proceedings in the case until the U.S. Supreme Court decides whether it will accept an appeal of the decision in this case.

The Federal Circuit issued its ruling today and remanded the case to the District Court for further proceedings based on the Federal Circuit's decision of August 2, 2005. The Federal Circuit has now reversed or vacated the infringement finding on 9 of the 16 litigated patent claims and has vacated the damages award and injunction originally entered as a result of the District Court trial in 2002.

RIM expects the District Court will decide all matters relating to the enforcement of the settlement agreement announced by the parties on March 16, 2005, the impact of the Patent Office re-examinations of the NTP patents on the litigation, and the further proceedings ordered by the Federal Circuit in its August 2, 2005 ruling. RIM also expects that NTP will imminently file a new motion asking the District 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.

In addition, RIM will ask the Supreme Court to suspend the court proceedings while RIM seeks Supreme Court review of the case. While 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.

All of the NTP patent claims have now been rejected by the Patent Office in its initial rulings in re-examination proceedings, based in part on prior art not considered in the District Court trial in 2002.
