     As the final step of the acquisition process, the remaining shares of
Murex will be acquired by an indirect wholly owned subsidiary of Abbott in a 
compulsory acquisition procedure for $13 per share. Under this procedure, a 
formal notice regarding the process for purchasing the remaining shares will
be sent to Murex shareholders. Given Abbott's controlling interest in Murex,
Abbott will own 100 percent of Murex upon completion of the compulsory
acquisition procedure.

     Under the terms of Abbott's March 16, 1998, definitive agreement with
Murex, Abbott will pay the Murex equity holders approximately $234 million, net
of the exercise price on existing Murex options, for 100 percent of the equity
in Murex.

     Murex develops, manufactures and markets a wide range of products for the
detection, screening and monitoring of infectious diseases and other medical
conditions.

     Abbott Laboratories is a global, diversified health care company devoted to
the discovery, development, manufacture and marketing of pharmaceutical,
