Waterloo, ON - Research In Motion Limited ("RIM") (Nasdaq: RIMM; TSX: RIM) announced today that a wholly-owned subsidiary of RIM will be extending the expiry date of its offer to acquire all of the outstanding common shares of Certicom Corp. ("Certicom") (TSX: CIC) for CDN $1.50 in cash per share from January 15, 2009 to 5:00 p.m. (Toronto time) on January 27, 2009.  All other terms and conditions of the offer remain unchanged. The formal notice of extension will be mailed to Certicom's shareholders next week.
