Form of the securities: the shares shall be bearer shares. The settlement of the operations will only take place in a book-entry form through Euroclear Belgium (transfer between accounts). Thresholds of listing: As provided in the ETA Nr 2004-433 dated 20 September 2002, the static price range will be set at +/-20% around the reference price. If the price is outside the static price range the stock will be reserved during 15 minutes. The new reference price used will be the treshold (up or down) reached previously. The static price range will be set at +/- 10% of this new reference price. This procedure will be repeated until an opening price will be established. At the opening of the security, the opening price will be the new reference price with a static price range of +/-10% and a dynamic price range of +/-5%.
