Directorate Change

Cookson Group PLC 05 May 2004 5 May 2004 DIRECTORATE CHANGE Cookson Group plc announces that Stephen Howard intends to relinquish the role as Group Chief Executive, after the identification and appointment of a successor. The process of identifying a successor has commenced and the Board envisages that an appointment will be made during the course of 2004. Accordingly, it is expected that Mr Howard will leave the Company on or before 31 December 2004. Stephen Howard has been a Director of Cookson since 1992 and Group Chief Executive since 1997. During the seven years of his tenure as Group Chief Executive, Cookson has been fundamentally reshaped into a highly focused group, centred around Electronics and Ceramics, with the Precious Metals division the subject of an ongoing strategic review, as announced on 15 March 2004. Stephen Howard said: 'My eighteen years at Cookson, including twelve on the Board and seven as Chief Executive, have been enormously fulfilling, but the time has simply come to do something else. The Company is now in excellent competitive shape and the long-awaited recovery is clearly underway, making this year the appropriate time to pass the baton on.' Bob Beeston, Chairman of Cookson, said: 'The Board of Cookson is very grateful for Stephen Howard's contribution to, and leadership of, the Company over many years. After three years of very difficult trading conditions, Cookson is now firmly on the recovery path, is in a sound financial position and is therefore very well positioned to prosper under his successor. The Company will continue to enjoy Stephen's leadership whilst we identify a suitable candidate to take over from him.' An announcement concerning a successor will be made at the appropriate time.
