STONESOFT RECEIVED ORDER FROM RUSSIA AT THE VALUE OF USD 1.9 MILLION

Stonesoft has received an order from a major Russian telecom operator
at the value of USD 1.9 million. The order includes Stonesoft's
StoneGate network security products and is related to renewing the
network of the operator. The order is a one-time order. Stonesoft has
not delivered its products to the customer before. The delivery will
take place during this year."We are really pleased about this order and it further strengthens
Stonesoft's position in Russia. The order manifests our success to
invest in expertise of large and critical service offerings", said
Ilkka Hiidenheimo, CEO of Stonesoft Corporation.

The order is strategically significant to the company and a very
large one-time order in this category. Based on finance market
turbulence, this order unlikely does not change the previous estimate
given by the company regarding the net sales and operating results
for the full year. The effect of the order will become visible during
this year and its effects on the development of the company's net
sales and operating result in the coming years in form of possible
further orders cannot be estimated at this point.
