                              Lawrence plc
                     Update on Aivlosin Registration

Following  the  meeting of the EMEA Committee for  Veterinary  Medicinal
Products (CVMP) on 17 March we have been given a timetable which advises
us  that  an official CVMP opinion will be given early in May which  may
lead  to a full European registration by the end of June 2004. In  which
case,  ECO  is  expecting to start marketing Aivlosin in Europe  in  the
second half of this year.
