Transparency notification of Schwarz Vermögensverwaltung GmbH & Co, Financière de Tubize SA and UCB SA/NV

Shareholding on 29 September 2011 (according to Article 6 and 14 of the law of 2 May 2007 on the disclosure of large shareholdings).

Brussels (Belgium), October 5, 2011 – 19:00 PM CET - regulated information - As a result of transactions carried out by UCB SA/NV on 29 September 2011 relating to its own securities, UCB SA/NV received on 5 October 2011 various transparency notifications.

On 29 September 2011, UCB SA/NV carried out the following transactions: UCB SA/NV first sold 704.733 UCB SA/NV-shares, and later acquired 1.400.000 options on UCB SA/NV-shares. Afterwards, UCB SA/NV acquired OTC 1.114.259 UCB SA/NV-shares with voting rights from KBC Bank NV.

As a result of these transactions, UCB SA/NV holds more than 3% of its own voting rights (2,18% attached to the shares it holds and 1,20% to the options on its own shares, assuming that all options would be exercised). In addition, UCB SA/NV crosses, together with UCB Fipar SA and UCB SCA the threshold of 5% of the voting rights to UCB SA/NV (3,90% attached to the shares they hold and 1,20% to the options on UCB SA/NV-shares, under the same assumption). This information arises from each of the transparency notifications UCB SA/NV has received.

Furthermore, KBC Bank NV currently no longer holds any UCB SA/NV-shares in concert with Financière de Tubize SA. This has led to a transparency notification. The number of shares held by the concert between Financière de Tubize SA and Schwarz Vermögensverwaltung GmbH & Co KG henceforth reaches 41,44% of the voting rights to UCB SA/NV, and even 42,64% when taking into account the options held by UCB SA/NV on its own shares and once again assuming that all options would be exercised. For this reason, this concert made a transparency notification.

Finally, in order to properly inform the general public, the information relating to all concerts to which Financière de Tubize SA is a party (i.e., the concert with Degroof Corporate Finance SA, Imofig Sa and Levimmo SA; the one with Compar Finance SA; and the one with Pharmahold SA and Cosylva SA) was updated.

A chart with the total number of securities and the percentage of voting rights attached thereto is included in the corporate governance charter of UCB SA/NV, which is published on UCB SA/NV’s website. UCB SA/NV also published the transparency notifications on its website.
