               ECO receives further drug marketing authorisations

Lawrence  plc  is pleased to report that its Eco Animal Health (Eco)  subsidiary
has received further marketing authorisations for Ecomectin, its veterinary anti-
parasitic endectocide.

These  approvals  have  been  received through the European  Mutual  Recognition
Procedure  (MRP) and will now allow Eco to market Ecomectin injection in  eleven
key  European markets for the treatment of pigs. Ecomectin injection is  already
authorised  for  the  treatment of cattle and sheep.  A  further  round  of  MRP
applications  is  in  process  to extend this claim  for  pigs  into  additional
important European markets.

Peter Lawrence, Chairman of Lawrence plc commented:
"This further authorisation is another important and valuable step for Eco. It
will enable us to extend our sales effort by providing new applications within
the fast growing European market for animal health products"
