PRESS RELEASE

ARCADIS PLANREALISATIE BV TAKES FINE FROM DUTCH COMPETITION AUTHORITY INTO CONSIDERATION

ARNHEM, The Netherlands, December 19, 2003—ARCADIS NV (Nasdaq: ARCAF; Euronext: ARCAD) today acknowledged receipt of a decision from the Dutch Competition Authority in which its subsidiary ARCADIS Planrealisatie BV was fined € 369,000 for the role it played in the construction of athletic tracks in the period 1998-2000. The Company has the decision under consideration.

Within ARCADIS Planrealisatie BV, the contracting activities of ARCADIS are concentrated. These activities comprise less than 5% of the total gross revenue of ARCADIS. A part of these activities has been reduced in the recent past. In addition, ARCADIS has implemented a worldwide integrity code in the beginning of 2003. Through active integrity management programs this should warrant sound and transparent business operations.

With client success central to our total business approach, we fulfill project or program needs from concept to completion and beyond. Together, we generate EUR 850 million in annual revenues.
