2011 at 12:45 p.m.


TRIMBLE TO COMPLETE THE PUBLIC TENDER OFFER FOR ALL THE SHARES IN TEKLA
CORPORATION SUBJECT TO FINAL RESULTS OF THE OFFERING

The extended offer period in the public tender offer by Trimble Finland Oy
("Trimble Finland"), a wholly owned indirect subsidiary of Trimble Navigation
Limited, for all of the issued and outstanding shares in Tekla Corporation
("Tekla") that are not owned by Tekla (the "Tender Offer") expired on 27 June
2011.

According to the initial result of the Tender Offer, the shares tendered in the
Tender Offer represent approximately 99.46 percent of all the shares and votes
in Tekla. All the conditions to completion of the Tender Offer have been
fulfilled provided that the final results of the Tender Offer confirm the
current estimate that over 90 percent of the shares in Tekla have been tendered.
Subject to this confirmation, Trimble Finland will complete the Tender Offer in
accordance with its terms and conditions.

The offer consideration will be paid to the shareholders who have validly
accepted the Tender Offer in accordance with the terms and conditions of the
Tender Offer after the final results have been confirmed. The final offer price
is expected to be paid on or about 8 July 2011, as of which date the ownership
of the tendered shares will be transferred to Trimble Finland.

The Board of Directors of Tekla may decide to pay a distribution of up to EUR
18,000,000 in the aggregate based on the authorization of Tekla's annual general
meeting held on 6 April 2011. In the event that the Board of Directors resolves
to distribute an additional dividend pursuant hereto, and a shareholder who has
accepted the Tender Offer is entitled to such distribution of additional
dividend or other assets, the additional dividend paid or other assets
distributed will, pursuant to the terms and conditions of the combination
agreement between Tekla and Trimble Navigation Limited and the terms and
conditions of the Tender Offer, be deducted from the offer price. Based on an
additional dividend payment of EUR 0.80 per share, the final offer price would
be EUR 14.20 per issued and outstanding share.

Trimble Finland's intention is to acquire all the shares in Tekla. As Trimble
Finland's ownership upon completion of the Tender Offer is expected to exceed
nine-tenths (9/10) of the shares and voting rights in Tekla, Trimble Finland
will initiate compulsory redemption proceedings for the remaining shares in
Tekla under the Finnish Companies Act. Trimble Finland may purchase shares in
Tekla also in public trading on NASDAQ OMX Helsinki or otherwise at a price not
exceeding the offer price.
