CAUTIONARY ANNOUNCEMENT RELATING TO THE

POSSIBLE DISPOSAL OF AECI'S INVESTMENT IN POLIFIN LIMITED

SHAREHOLDERS OF AECI ARE REFERRED TO THE ANNOUNCEMENT PUBLISHED TODAY BY SASOL
LIMITED ("SASOL") IN WHICH SASOL ADVISES ITS SHAREHOLDERS THAT SASOL INTENDS TO
COMMENCE DISCUSSIONS WITH AECI WHICH, IF SUCCESSFULLY CONCLUDED, MAY LEAD TO
SASOL ACQUIRING AECI'S INTEREST IN POLIFIN LIMITED ("POLIFIN").

IN AN ANNOUNCEMENT TO AECI SHAREHOLDERS ON 21 OCTOBER 1998, A TRANSFORMATION
STRATEGY FOR AECI WAS COMMUNICATED WHICH INCLUDED THE EXIT FROM HIGH CAPITAL,
CONTINUOUS PROCESS COMMODITY CHEMICAL BUSINESSES. SPECIFIC MENTION WAS MADE
THAT AECI MAY CONSIDER DIVESTING FROM ENTITIES SUCH AS POLIFIN, BUT THAT THE
TIMING OF ANY SUCH DIVESTMENT WOULD DEPEND ON MARKET CIRCUMSTANCES.

WHILE SASOL HAS INDICATED ITS INTENTION TO COMMENCE DISCUSSIONS TO ACQUIRE
AECI'S INTEREST IN POLIFIN, AECI HAS AT THIS TIME NOT RECEIVED ANY OFFER FROM
SASOL AND HAS NOT RECEIVED ANY INDICATION AS TO THE TERMS, CONDITIONS OR PRICE
AT WHICH SUCH OFFER COULD BE MADE. THE RESPONSE OF AECI TO ANY OFFER FROM SASOL
WILL HAVE REGARD TO THE BEST INTERESTS OF AECI SHAREHOLDERS.

AECI SHAREHOLDERS ARE ADVISED TO EXERCISE CAUTION IN DEALING IN THEIR AECI
SHARES UNTIL SUCH TIME AS A FURTHER ANNOUNCEMENT IS MADE IN THIS REGARD.
