Stonesoft Corporation Stock Exchange Release December 20, 2012 at 10:55 a.m.

STONESOFT SEGREGATES PART OF ITS SERVICE BUSINESS TO ITS SUBSIDIARY

Stonesoft segregates its post sales technical support by selling it to its newly
founded, fully owned subsidiary Stonesoft Global Support Ltd. The new company
will from now on perform the technical support services offered to Stonesoft's
customers as a subcontractor. The contracts between Stonesoft and its customers
remain unchanged. The support service business personnel will be transferred to
the new company as old employees. The incorporation will not affect current
customers' service level or contractual relations. In the long run the
transaction enables a more flexible development of post sales technical support.
Based on Stonesoft's understanding, it is likely that along with the
geographical expansion the need to offer services in other languages than
English will grow, which is likely to result in e.g. establishing additional
service sites. This transaction supports the company's growth strategy.

The internal transaction, the price of which has been set to MEUR 18.5, will be
effective on December 31st, 2012. The price is based on external valuation of
the fair price of the technical support business. The purchase price will remain
as debt of Stonesoft Global Support Ltd to Stonesoft Corporation. The company
has received an advance ruling from the Finnish tax authorities related to the
tax handling of the case.
