MISSISSAUGA, Ontario, Sept. 20, 2004 - Astris Energi Inc. (OTCBB: ASRNF), the world's leading alkaline fuel cell (AFC) technology company, today announced that it has signed a Memorandum of Understanding with Macnor Corp. for the purchase of Macnor's 70% share of Astris s.r.o., Astris Energi's affiliate company in the Czech Republic. With the completion of this purchase, Astris will own 100% of the issued and outstanding shares of Astris s.r.o.

Under the terms of the Memorandum, Macnor will receive an aggregate consideration of 5,000,000 purchase units.

The warrants expire three years from the closing date.

Since Macnor Corp. is controlled by Jiri K. Nor, President, CEO and Director of Astris Energi, the transaction was negotiated by a special committee of the Astris Energi Board of Directors.

The acquisition is subject to all regulatory rules and other approvals dealing with related party transactions, including shareholder approval.
