Research In Motion Records Provision For NTP Inc. vs. RIM Litigation

Waterloo, ON - Research In Motion (RIM) (Nasdaq: RIMM; TSX: RIM) today provided an update with respect to the fourth quarter financial impact of the NTP Inc. litigation resulting from the February 28th, 2003 hearing. Following the completion of a legal and financial analysis of the Court's rulings, the Company has decided to take a provision of between $7 million and $8 million in the fourth quarter of fiscal 2003.

The Court ruled on two procedural issues at the February 28th hearing. The first ruling set the pre-judgment interest rate on damages at the prime rate. The second ruling ordered RIM to provide, for the purposes of determining potential damages, an accounting through February 28, 2003 of RIM's U.S. sales of products and services that the jury had found to infringe in its November, 2002 verdict. The Court did not rule on key post-trial motions and ordered the parties to mediation before a U.S. Magistrate Judge.

As a result of these rulings, RIM expects to record a pre-tax provision in the fourth quarter of between $7 million and $8 million. This accrual encompasses the Company's estimate for: a potential increase in damages beyond the previously announced $23 million awarded by the jury in November, 2002; the Company's estimate for pre-judgment interest at the prime rate; and an increase to RIM's current and future legal fees provision as previously recorded. This brings the estimated fiscal 2003 provision recorded to date to between $39.7 million to $40.7 million. This provision is subject to the outcome of mediation, final rulings and potential appeals.

The fourth quarter provision excludes any allowance for plaintiff's attorney's fees and any other potential damages or other awards resulting from motions upon which the Court has not yet ruled.

Other than the accrual described above, the Company has not altered its guidance for the fourth quarter of fiscal 2003. RIM is scheduled to report its fiscal fourth quarter and year end results after the market close on April 3, 2003.

The litigation between NTP Inc. and RIM remains before the Court. Further comment and details were not disclosed.
