He will combine this role with his new position on the Executive Board and will also assume responsibility for the environmental business line of ARCADIS. Mr. Blake has been with ARCADIS U.S. and predecessor companies since 1987 in various managerial roles. Given his experience in the industry and the successful leadership he has provided to ARCADIS' U.S. operations, the Supervisory Board considers him eminently qualified to assume his expanded role. Mr. Perez was an external member of the Board of Malcolm Pirnie until that company joined ARCADIS in July 2009. As such he has broad knowledge of the consultancy and engineering business particularly with the water related activities of Malcolm Pirnie. He has spent almost his entire professional career with Exxon and ExxonMobil in senior managerial roles at the local, regional and global levels. The experience of Mr. Perez with a major multinational company is also relevant in view of ARCADIS' ambition to expand its business with this client category across the globe.
