                             On September 26, 1997,  the Company  announced that
                    the labor unions  representing the workers of Sintel,  S.A.,
                    the  company's  Spanish  subsidiary,   have  announced  work
                    stoppages at Sintel in response to Sintel's  application  to
                    the Spanish labor  authorities to restructure  Sintel's work
                    force.  The unions  announced that the workers will not work
                    two half days per week until a labor  agreement  is reached.

                    the application in mid to late October.

                    the  foregoing  event, a copy of which  is  attached  as
                    exhibit 99.1 which is incorporated  herein by reference.
