YIT CORPORATION STOCK EXCHANGE RELEASE March 10, 2010 at 18:05 YIT IMPLEMENTS A SHARE-BASED INCENTIVE SCHEME The Board of Directors of YIT Corporation has decided to implement a new share-based incentive scheme. The objective of the incentive scheme is to support YIT's strategy of profitable growth and supplement the already available incentive schemes. YIT's objective is providing its employees competitive terms of employment, including various incentive schemes as well as opportunities for development and participation. The share-based incentive scheme aims at promoting the employees in determined work, rewarding their good performance and committing them to long-term persistent work. The scheme consists of three earnings period, i.e., the calendar years 2010, 2011 and 2012. Shares will be handed over in 2011, 2012 and 2013 to employees, based on the results of the previous year. A total of approximately 700,000 shares can be annually rewarded, of which a maximum of 20,000 to the President and CEO. Furthermore, employees included in the scope of the incentive scheme will receive part of their reward in cash to cover the deferred taxes and other charges ordered by the authorities caused by the share rewards. Employees included in the scope of the incentive scheme are obliged to not transfer their shares within two years of having obtained them; i.e., during a commitment period. If the employment of an employee included in the scope of the scheme is terminated during the commitment period, the employee must return any shares obtained as rewards to the company free of charge. Under all circumstances, the Board has the right to amend the rewards in a reasonable manner. The Board of the company annually decides on the performance criteria and the employees included in the scope of the incentive scheme. In the case of 2010, the performance criteria are return on investment and revenue growth, and the incentive scheme covers approximately 250 employees whom the Board will name by the end of March 2010.
