PSI AG Executive Board Decides on Continuation of Share Buyback

The Executive Board of PSI AG (ISIN DE0006968225) decided on 4 May 2009 to
buy back up to 800,000 of its own shares (this corresponds to approx. 6.7
percent of the capital stock) through the stock exchange.

The decision follows the authorization of the Annual General Meeting on 25
April 2008 for the buyback of own shares of up to 10 % of the capital
stock. The buyback program is limited to 30 September 2009. The shares may
be used for all the purposes authorized in the General Meeting. This
includes in particular the use as acquisition funds for the upcoming
corporate acquisitions. The purchase price per share may not exceed the
closing price per share of the Xetra trading system on the preceding day by
more than 10%, nor may it be less than 20% below the same price.
