Nuance Communications, Inc. (NASDAQ: NUAN) today announced that it is extending its previously announced offer to purchase all of the outstanding common shares of Zi Corporation (NASDAQ: ZICA, TSX: ZIC) for US$0.40 per share in cash to 5:00 p.m. (Calgary time) on February 13, 2009, unless further extended or withdrawn. The tender offer, which was previously scheduled to expire at 5:00 p.m. (Calgary time) on January 30, 2009, has been extended to provide Zi shareholders additional time to consider the merits of the offer. All other terms and conditions of the tender offer described in the offer to purchase and accompanying circular dated November 26, 2008, as amended on December 3, 2008, remain unchanged.
