NOTIFICATION OF A CHANGE IN SHAREHOLDING PURSUANT TO CHAPTER 9, SECTION 5 OF THE
FINNISH SECURITIES MARKET ACT

Stonesoft Corporation has on 12 June 2013 received the following notification in
accordance with the Securities Markets Act from Intel Corporation (Delaware
Secretary of State File No. 2189074) and its wholly-owned indirect subsidiary
McAfee Suomi Funding LLC (Delaware Secretary of State File No. 5328874):

If the tender offer for all the shares and option rights in Stonesoft
Corporation is completed, the ownership of McAfee Suomi Funding LLC in Stonesoft
Corporation will, based on the shares and option rights tendered into the tender
offer by 11 June 2013, conditional upon the completion of settlement trades,
exceed 2/3 of all the shares and voting rights in Stonesoft, based on the tender
offer published on 6 May 2013 for the shares and option rights as well as the
irrevocable undertakings of the three largest shareholders of Stonesoft.

According to the notification the ownership of McAfee Suomi Funding LLC,
conditional upon the completion of the tender offer, (including the irrevocable
undertakings given by the three largest shareholders of Stonesoft Corporation to
accept the tender offer) would, after the completion of the offer be 44,003,778
(66.91%) shares and votes, assuming that all option rights offered in the tender
offer would be used to subscribe shares.

Intel Corporation has on 6 May 2013 published a public tender offer made by its
subsidiary McAfee Suomi Funding LLC, for all issued and outstanding shares and
option rights in Stonesoft Corporation. The offer period for the tender offer
