Conflicts of interest and voting instructions

According to article 7:143 of the Belgian Companies and Associations Code (the "CAC"), a conflict of interest arises between the shareholder and his proxy, when the proxy holder: (1) is the Company itself or one of its subsidiaries, or a shareholder controlling the Company or an entity controlled by such shareholder, (2) is a member of the management body of the Company or one of its subsidiaries, or of a shareholder controlling the Company or of an entity controlled by such shareholder, (3) is an employee or statutory auditor of the Company or one of its subsidiaries, or of a shareholder controlling the Company or of an entity controlled by such shareholder,(4) has a parental relationship with a natural person as referred to in (1) through (3), or a spouse or legal cohabitating partner of such person or of a relative of such person.

In the event of such a conflict of interest, the following rules shall apply:

1. the proxy holder must disclose the precise facts that are important to the shareholder in order to assess whether there is a risk that the proxy holder would pursue any interest other than the interest of the shareholder; and

2. the proxy holder may only vote on behalf of the shareholder on the condition that he disposes of specific voting instructions for each agenda item.

SIPEF therefore invites you to issue specific voting instructions by ticking the boxes below for each item on the agenda of the Meeting.

If no specific voting instruction is provided on the proxy form for an item on the below agenda, it shall be assumed that the proxy holder has been specifically instructed to vote "FOR" this item.

The proxy holder shall ABSTAIN from voting on new topics to be discussed that, in application of the legal and statutory provision in this regard, would be added to the agenda at the request of certain

shareholders. (Please strike through the preceding phrase should you expressly wish to mandate your proxy to vote on such agenda items.)

Agenda of the Meeting
