Should the Ordinary General Meeting of Shareholders not be able to deliberate validly or should it be postponed for any reason whatsoever, the aforementioned special proxyholder is authorized to attend any subsequent meeting having the same or a similar agenda. However, this shall only apply insofar the principal has in due time complied with the required formalities to participate and vote at the subsequent ordinary general meeting of shareholders.

The effect of (possible) exercise of the right to add items to the agenda and to file proposed resolutions on the proxy form

One or more shareholders holding alone or together three per cent (3%) of the share capital of the company can exercise his/her/its/their right in accordance with section 533ter of the Belgian Companies Code to add to the agenda of the Ordinary General Meeting of Shareholders one or more items to be dealt with and to file proposed resolutions relating to items already on or to be added to the agenda.

In any such case, the company will no later than Monday, 30 April 2018, make available to its shareholders on its website under "Investor Relations" – "Shareholders' meeting" (www.eliagroup.eu) the relevant forms that can be used to vote by proxy, to which are added the additional items to be dealt with and the attendant proposed resolutions that might be placed on the agenda and/or just the proposed resolutions that might be formulated.

In that case, the following rules will apply:

(a) If the present proxy has been validly notified to the company before publication of the revised agenda of the Ordinary General Meeting of Shareholders (i.e. on Monday, 30 April 2018 at the latest), it will remain valid with regard to the items mentioned on the agenda for which it was given;

• (b) If the company has published a revised agenda including one or more new proposed resolutions for items which were initially mentioned on the agenda, the special proxyholder may deviate from any instructions given by the principal if execution of such instructions might compromise the principal's interests. In that case, the special proxyholder must inform the principal thereof.
• (c) If the company has published a revised agenda including one or more new items to be dealt with, the proxy must indicate whether or not the special proxyholder is authorised to vote on these new items or whether he/she should abstain. In view of the foregoing, and as applicable, the special proxyholder must: 4
• □ abstain on the new items and the attendant proposed resolutions that might be placed on the agenda of the Ordinary General Meeting of Shareholders;
• □ vote on the new items and the attendant proposed resolutions that might be placed on the agenda of the Ordinary General Meeting of Shareholders, as he/she considers appropriate, taking into account the principal's interests.

If the principal has not marked either of these boxes or if the principal has marked both boxes, the special proxyholder must abstain from voting on the new items and the attendant proposed resolutions that might be placed on the agenda of the Ordinary General Meeting of Shareholders.
