Cookson Group plc ('Cookson'), a leading materials science company, announces
that it has today completed the disposal of the Carbon Bonded Ceramics business

On 11 January 2008, it was announced that a conditional agreement had been

the acquisition of Foseco by Cookson on 4 April 2008 and confirmation from the
European Commission and the United States Department of Justice that this sale
satisfies the condition concerning CBC included in the anti-trust clearances
obtained on 4 March 2008, the sale of CBC to RHI has now been completed.

CBC had revenue of approximately £19 million for the year ended 31 December 2007
and gross assets of approximately £8 million as at 31 December 2007.
