Proposed resolution

The meeting decides to renew the authorization to the board of directors, to increase, in accordance with the circumstances and purposes stated in the report in compliance with article 7:199 of the Companies Code, the capital in one or more installments by an amount of forty-four million seven hundred and thirty-three thousand seven hundred and fifty-two United States dollars and four cents (USD 44 733 752.04) for a period of five (5) years from the date of the publication in the Annexes to the Belgian Official Journal (Belgisch Staatsblad/Moniteur belge) of the decision of the extraordinary general meeting on that matter, and accordingly amend in the text of Article 6 of the Articles of Association the date "June 2020" to 14 June 2023, so that the article will read:

"Article 6: Authorized capital"

6.1. The board of directors is authorized to increase the capital by notarial deed in one or more installments by an amount of forty-four million seven hundred and thirty-three thousand seven hundred and fifty-two United States dollars and four cents (USD 44 733 752.04). The board of directors may exercise this power for five (5) years after the publication in the Annexes to the Belgian Official Journal of the decision by the extraordinary general meeting of 14 June 2023 to amend the articles of association with regard to the renewal of the authorization.

This authorization may be renewed in accordance with the applicable legal provisions.

The board of directors may also exercise this power in accordance with the procedures set down in points 2 and 3 below, for a period of three (3) years from the publication in the Annexes to the Belgian Official Journal of the amendment to the articles of association as decided by the extraordinary general meeting of 14 June 2023 in the event of a public bid to acquire the securities of the company, as referred to in Article 7:202 of the Companies Code.

This authorization may be renewed in accordance with the applicable legal provisions.

• 6.2. The capital increases decided upon pursuant to this authorization may occur in accordance with the procedures to be established by the board of directors, such as:
  • by means of a contribution in cash or in kind within the limits permitted by the Companies Code
  • by converting reserves and share premiums
  • with or without issue of new shares, with or without voting rights
  • by issuing convertible bonds, whether subordinated or not
  • by issuing subscription rights or bonds to which subscription rights or other securities are attached
  • by issuing other securities, such as shares under a share option plan.
• 6.3. In the interests of the company, the board of directors can limit or cancel the preferential right of the shareholders, within the limits and in accordance with the conditions set down in the Companies Code. This limitation or cancellation may also occur in favor of one or more specific persons or in favor of the personnel.

If an issue premium is paid as a result of an increase in the authorized capital, this will be automatically, after deduction of any possible costs, booked on the "Issue Premiums" account, which will constitute the guarantee for third parties to the same extent as the share capital and which, save the possibility of conversion into capital, may only be used in accordance with the conditions laid down by the Companies Code for the amendment of articles of association. The board of directors has the power, with the possibility of substitution, to bring the articles of association in line with the new situation of the capital and the shares after each capital increase within the limits of the authorized capital."

of the Companies Code, without the prior permission of the general meeting of shareholders.

These shares may also be disposed of under share option plans in favor of directors, self-employed staff members and/or members of personnel of the company and/or companies in which the company, alone or by virtue of a shareholders' agreement, directly holds, exercises, or controls the majority of the voting rights, or in which the company has the right to directly appoint the majority of directors or managers.
