Montreal, Canada - Alcan Inc.

An agreement on the sale was announced December 29, 2004, and its completion follows the approval by the Greek Competition Commission and the Greek Ministry of Development.

'We are pleased to have completed this transaction and welcome the commitment demonstrated by Mytilineos toward AdG?s long term success,' said Cynthia Carroll, President and Chief Executive Officer, Alcan Primary Metal Group.
