     Telecommunications Inc. ("Microcell"), and consideration of Cdn.$29.00
     per Class A Share in cash plus (2) the product of 34,827,210 (which
     includes 5,747,857 outstanding stock options and warrants for) class B
     non-voting shares ("Class B Shares"), of Microcell and the tender offer

     May 3, 2004 as set forth in a press release issued by Microcell, dated
     May 5, 2004, which was attached to a Form 6-K filed by Microcell with the
