AT&T UPDATE

                     "Last  week we  announced  plans  to  create  four new AT&T
                     companies.  Each will move faster to meet  customer  needs.
                     And I can  assure all AT&T  customers  --  individuals  and
                     businesses  -- that each  company  will  offer the  bundled
                     services  customers  want  over its  facilities.  And do it
                     better than anyone else."
