Dear Sir
Resignation of Alan McGregor
James Hardie regrets to advise that former Chairman, Mr Alan McGregor, has today resigned as a Director, due to continuing ill health. Mr McGregor’s medical treatment means it is difficult for him to continue his directors’ duties until his planned retirement in September. Mr McGregor’s resignation as Director is effective immediately.
The Company acknowledges the long and valuable contribution that Mr McGregor has made to the development of James Hardie. The Board and management extend their best wishes for his full recovery.
Yours faithfully
/s/ Pim Vlot
Pim Vlot
Company Secretary
