Research In Motion Limited announced yesterday that it has received a copy of an unsolicited “mini-tender” offer made by TRC Capital Corporation , pursuant to which TRC Capital has offered to purchase up to 1,000,000, or approximately 0.5%, of the outstanding common shares of RIM. The offer price of Cdn$69.00 per common share represents a 2.89% discount to the Cdn$71.05 closing price for RIM’s common shares on the Toronto Stock Exchange on November 1, 2005, the day before the offer was made.

RIM wishes to inform its shareholders that it does not recommend or endorse this unsolicited offer, and that RIM is not associated with TRC Capital, the offer or the offer documentation. TRC Capitals unsolicited offer is not related to RIMs previously announced plan to repurchase, from time to time, up to 9,500,000 of its common shares on the Nasdaq National Market.

Securities regulators in the United States and Canada have recommended that shareholders exercise caution in connection with “mini-tender” offers and that they consult their investment advisors regarding these types of offers.
