Possible Fast Track Inclusion Of Belgacom In The BEL20®-Index - Scenario

Following the announced listing of Belgacom on the first market of Euronext Brussels you will find the scenario that will be applied if and when the listing is confirmed.

In this scenario, it has to be taken into account that the prospectus contains a number of unknown elements concerning the final number of admitted shares on the one hand and the final IPO price on the other hand. Therefore it is important to note that the publication of the weights of the shares in the new index basket is purely indicative and based upon following assumptions:

• for the calculation we assume that a total of 387.619.050 shares will be admitted;
• two indicative baskets are calculated: one based on a price of 23 euro (lowest level of the published range) and another one based on a price of 26.5 euro (highest level of the published range).

Following rule 1.4 c) of the index rules a new security which ranks in position 10 or higher in the selection list immediately enters the BEL20® index. For the calculation of the data used for the selection list and relative to a new listing, the prospectus information is used (rule 5.3.4 a). Following this calculation, the free float of Belgacom has to be rounded up to 40%. The market capitalisation is calculated on the base of the price range and the number of shares mentioned above.

The ranking and the selection are based on the selection list, which is valid at the moment of the first listing, being the one calculated at the end of February (rule 5.3.2). The list is annexed. This list is valid for all replacements that would occur from 16 March up to and including 15 April after market close. In case of withdrawal, Tessenderlo would become first reserve candidate, followed by Deceuninck and CMB

Due to the importance of the changes, all weightings will be adapted on the base of the selection list on the one hand and, for Belgacom, on the IPO price on the other hand (rule 5.5.3).

Based on the data mentioned above, Belgacom ranks eighth of the selection list at a valuation of 23 euro (lowest price). Consequently, Belgacom is considered for immediate inclusion in the BEL20®-index.

As the final IPO price is unknown, only a conditional and indicative calculation (on the highest and the lowest prices) of the new basket can be published.

Following announcements will follow:

22 March after close: Announcement of the final composition of the basket

25 March: Confirmation of the changes (end of "if & when" period)

29 March after close: Effective change of the basket and inclusion of Belgacom replacing Tessenderlo.
