Press Release







Montreal, Canada, Paris, France - September 5, 2003 - Alcan Inc. (NYSE, TSX: AL) announced today that the French Treasury Department cleared Alcan's offer to acquire Pechiney securities [NYSE: PY, Paris: PEC] filed on July 7, 2003. The decision followed a period of intensive review and consultation.

Alcan's plans for Pechiney's operations, allow Alcan to respond to the expectations of the French Government in aerospace and defense matters, in research and development, and in maintaining industrial sites and employment in France.

Commitments made by Alcan relate in particular to the continuity of operations at industrial sites, except those which Pechiney has, as of today, announced would be closed, and the location in France of the world headquarters for packaging operations, the world headquarters for aerospace operations, the global headquarters of new cell technology for primary aluminum and the European headquarters for primary aluminum operations.

Alcan is pleased that its willingness to ensure the continuity of Pechiney's French operations has responded to concerns raised by the French Government.

These commitments are the yardstick by which any alternative future plans for Pechiney will be measured.

Travis Engen, Alcan's President and Chief Executive Officer stated:

"I am very satisfied with the quality of the dialogue that we have established with the Government of France. We have done our utmost to respond accordingly to concerns expressed by the Government. France will have a prominent place within the combined entity - this is why Alcan is eager to establish a relationship with the French public authorities based on trust and cooperation. Our plans are built on a solid economic model. The combination of Alcan and Pechiney will, while creating value, allow for economic development and will support employment. This is the best option for Pechiney and its employees."

The French Government's clearance will permit the launch of the Alcan's previously announced public offer, once the French stock exchange authorities approve the final form of the offer documentation.

Alcan is a multinational, market-driven company and a global leader in aluminum, packaging, and recycling with 2002 revenues of US$12.5 billion. With world-class operations in primary aluminum, fabricated aluminum as well as flexible and specialty packaging, Alcan is well positioned to meet and exceed its customers' needs for innovative solutions and service.
