The Board of Directors of Vaisala Corporation Resolved on Key Employees' Share-
Based Incentive Plan

Vaisala's Board of Directors has resolved for the Group key employees a share-
based incentive plan that is based on the development of Group's profitability
in calendar year 2018. The reward will be paid partly in the company's series A
shares and partly in cash in spring 2021. The cash proportion will cover taxes
and tax-related costs arising from the reward to a key employee. No reward will
be paid if a key employee's employment or service ends before the reward payment
date. The maximum amount of this plan corresponding to 160,000 shares will be
paid depending on the number of entitled persons at the end of vesting period.
