Fortum to acquire City of Oslo’s shares in Hafslund
- Major step in Nordic power and heat strategy

Fortum has agreed to acquire City of Oslo’s 53.7% share of capital
in Hafslund ASA for EUR 660 million (NOK 5.4 billion). On 9 May,
the Oslo City Board (Byrådet) signed the agreement and recommended
it to the City Council (Bystyret) for approval. With Hafslund,
Fortum can take a major step in the development of the leading pan-
Nordic power and heat company with significant skills and scale in
Norway, Sweden and Finland.

The acquisition of City of Oslo’s shares will enable Fortum to
gain control of Hafslund and is a major step in Fortum’s Nordic
power & heat strategy:

- Positions Fortum as #1 in Nordic and Norwegian retail

- Strengthens Fortum’s #1 market position in Nordic distribution
and positions Fortum as #1 in Norwegian distribution

- Strengthens Fortum’s #2 position in Nordic power generation

- Increases cash flows from stable distribution activities,
creates a larger customer base and broader geographic scope

- Provides EUR 20 million of annual synergy benefits by 2006

Oslo City Board has approved the agreement and it remains subject
to approval by Oslo City Council and that there are no higher
offers prior to early July. The transaction is expected to close
during the summer after which Fortum will own 87.8% of Hafslund’s
capital and will launch a mandatory tender offer to the remaining
minority shareholders at the same price.

“I am delighted that we can continue to deliver on our pan-Nordic
strategy, and that we have reached an agreement with the City
board of Oslo. We are an owner with strong industrial competence
and financial resources to develop Hafslund’s business in Norway
and beyondö, says Mikael Lilius, President and CEO of Fortum.

“Hafslund is a fine company with a long history and strong market
position. It fits excellently into our strategy. Together we can
combine key skills in the two companies in a way that will enhance
our competitiveness not only in Norway, but in all Nordic markets.
With this transaction we can continue to leverage skills and
experience in our Nordic organization to the long term benefit of
customers, employees and owners.ö Mikael Lilius concluded.

Transaction overview

Fortum has agreed to acquire City of Oslo’s 67,524,647 A-shares
and 37,342,907 B-shares in Hafslund ASA at a cash price of NOK
53.0 for A-shares and NOK 48.0 for B-shares for a total of EUR 660
million (NOK 5.4 billion). These shares represent 53.7% of
Hafslund’s share capital.

Fortum’s total acquisition price for 100% of Hafslund will be NOK
45.4 per share (EUR 1.1 billion or NOK 8.9 billion) including the
price paid for Fortum’s existing 34.1% holding in Hafslund and the
price to be paid to remaining minority shareholders. In addition,
Fortum will assume EUR 1.4 billion (NOK 10.9 billion) of net
financial debt.

The combination of Hafslund and Fortum, and the integration of
Fortum’s existing Norwegian assets with Hafslund, will create
significant business opportunities and are also expected to
generate EUR 20 million of annual synergy benefits by 2006. The
synergy benefits are in addition to Hafslund’s own announced
efficiency improvement target of approximately EUR 50 million. The
synergy benefits will be realised through the sharing of best
practices in operation and maintenance, economies of scale (e.g.
combined purchasing) and combination of competencies. The
transaction is expected to be accretive to Fortum’s earnings in
2006. The Aggregate Value / last twelve months EBITDA as of March
31, 2004 is 9.6x post synergies.

Due to Norwegian regulations governing ownership of hydroelectric
assets, Fortum will initially through the agreement with City of
Oslo and the tender offer acquire shares resulting in an aggregate
ownership of 89.9% of Hafslund. The acquisition of the remaining
City of Oslo’s shares remains subject to obtaining an exemption
from the regulatory concession requirement. If such exemption is
not granted, City of Oslo will remain a minority shareholder in
the hydroelectricity generation business while Fortum will fully
own all the remaining assets and operations of Hafslund.

The acquisition will be financed through bank borrowings. Fortum
is committed to manage Hafslund in full recognition of its
obligations to bondholders and other lenders. Over the medium
term, Fortum plans to repay debt incurred in the acquisition by
internal cash flows.
