extended offer period, the intention of Trimble Finland is to complete the
Tender Offer upon expiration of the extended offer period.

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 the company's annual
general meeting held on 6 April 2011. In the event that the Board of Directors
resolves to distribute a dividend pursuant hereto, the dividend paid or other
assets distributed will, pursuant to the terms and conditions of the Tender
Offer, be deducted from the offer price.
