     office of the corporation, not less than 90 days before the first 
     anniversary of the date of the preceding year's annual meeting of

     mailed and received not less than 90 days before such annual meeting or, 
     if later, within 10 days after the first public announcement of the date 
     of such annual meeting.  If a special meeting of shareholders of the

     first public announcement of the date of such special meeting or such
