Stuart Brown, chief financial officer and acting joint chief executive officer of the
De Beers Group, has decided to step down after nearly 20 years with the
company.

Brown will  stay on until July 31, to help Philippe Mellier settle into his new
role as CEO.

“During the past three years in particular, Stuart has led a comprehensive restructure and
a successful refinancing of the group all while seeing the company through the
most challenging financial crisis since World War II and helping it to post the best
financial results we’ve seen in more than a decade,” De Beers chairman Nicky
Oppenheimer said in a statement.

Brown joined De Beers in 1992 at the Premier (now Cullinan) Mine as internal auditor.
