The intention is that the next time share subscriptions related to Fortum share
option schemes are registered will be approximately on 15 March 2007, when
new shares subscribed for by 7 March 2007 will be registered. The shares
subscribed for with options by 7 March 2007 are entitled to a dividend possibly
paid for 2006 during the spring of 2007. The holders of these new shares are
entitled to participate in the Annual General Meeting in the spring of 2007
the terms indicated in the notice to the shareholders' meeting.

Since the subscription price of the shares subscribed for under any Fortum
scheme equals the nominal value of the share (EUR 3.40), any dividends paid do
not reduce the subscription price.
