Agenda item 5: renewal of the authorization to the Board of Directors to increase the share capital within the framework of the authorized capital by up to twenty per cent (20%) of the share capital

Consequently, the shareholders’ meeting resolved to delete the existing temporary provisions of the articles of association of the Company in their entirety and to replace them with the following text, which, together with the Share Buyback Authorization set out under agenda item 3, will form the new temporary provisions of the articles of association (whereby the amount of twenty per cent (20%) of the subscribed capital referred to between square brackets below shall be determined on the basis of the outstanding subscribed capital at that time):

“43. AUTHORIZED CAPITAL

The Board of Directors has been granted the authority to increase the subscribed capital of the company, in accordance with applicable law, in one or several times, to the extent set forth hereafter. This authorization is valid for a period of five years from the date of publication of this authorization in the Annexes to the Belgian State Gazette.

Without prejudice to more restrictive rules set forth by law, the Board of Directors can increase the subscribed capital of the company in one or several times with an amount of up to EUR [•], i.e. twenty per cent (20%) of the subscribed capital at the time of the convening of the shareholders’ meeting granting this authorization. In accordance with applicable law, the Board of Directors cannot use the aforementioned authorization after the Financial Services and Markets Authority (FSMA) has notified the company of a public takeover bid for the company’s shares.

The capital increases within the framework of the authorized capital may be achieved by the issuance of shares (below, above or at the fractional value of the existing shares, with or without voting rights, and as the case may be in the context of subscription right plans, restricted stock unit plans, performance stock unit plans and other incentive plans, for the company’s or its subsidiaries’ members of the personnel within the meaning of article 1:27 of the Belgian Companies and Associations Code (including members of the Board of Directors and/or independent consultants)), convertible bonds and/or subscription rights exercisable by contributions in cash or in kind, with or without issuance premium, and also by the conversion of reserves, issuance premiums, profits carried forward or other equity components. Aforementioned incentive plans can provide that, in exceptional circumstances (among others in the event of a change in control of the company or decease of the beneficiary), subscription rights, restricted stock units, performance stock units and other incentives can give rise to an accelerated exercise or vesting, before the third anniversary of their award, even if the beneficiary is a member of the Board of Directors or a person entrusted with the day-to-day management.

When increasing the subscribed capital within the limits of the authorized capital, the Board of Directors may, in the company’s interest, restrict or cancel the shareholders’ statutory preferential subscription rights, even if such restriction or cancellation is made for the benefit of one or more specific persons other than the company’s or its subsidiaries’ members of the personnel within the meaning of article 1:27 of the Belgian Companies and Associations Code.

The Board of Directors can ask for an issuance premium when issuing new shares in the framework of the authorized capital. If the Board of Directors decides to do so, such issuance premium is to be booked on a share premium account.

The Board of Directors is authorized to bring the company’s articles of association in line with the capital increases which have been decided upon within the framework of the authorized capital, or to instruct a notary public to do so.”

Until this proposed resolution is approved and published in the Annexes to the Belgian State Gazette, the existing authorization will continue to apply.

Agenda item 6: proxy for coordination of the articles of association

The shareholders’ meeting resolved to authorize each collaborator of undersigned notary or notary Matthieu Derynck to draw up, sign and file the coordinated text of the Company’s articles of association in the electronic database provided for that purpose under the applicable laws.

Agenda item 7: authorization to the Board of Directors

The shareholders’ meeting resolved to grant all powers to the Company’s Board of Directors to execute the decisions taken.
