The agenda of the Extraordinary General Meeting of Shareholders is as follows:

Double capital increase in favour of the personnel

• 1. Presentation of the report of the Board of Directors and of the report of the statutory auditors, both drawn up in accordance with sections 582 and 596 of the Belgian Companies Code, with respect to the possibility that class B shares might be issued at below the par value of the existing shares of the same class, with elimination of the preferential subscription right of the existing shareholders within the framework of the double capital increase as envisaged in item 2 of the agenda;
• 1. Double capital increase in a maximum total amount of EUR 6,000,000, composed of a first capital increase in 2018 (hereinafter the "2018 Capital Increase") in a maximum amount of EUR 5,300,000 and a second capital increase to be effected in 2019 (hereinafter the "2019 Capital Increase") in a maximum amount of EUR 700,000, by means of the issue of new class B shares, with elimination of the preferential

subscription right of the existing shareholders in favour of the personnel of the company and its Belgian subsidiaries, as the case may be at below the par value of the existing shares of the same class;

Proposed resolution: the Extraordinary General Meeting of Shareholders resolves:

1° to increase the capital within the framework of the 2018 Capital Increase with elimination of the preferential subscription right of the existing shareholders in favour of members of the personnel of the company and its Belgian subsidiaries, by a maximum of EUR 5,300,000, by means of the issue of new class B shares subscribed in cash and fully paid up, which have the same rights and benefits as the existing class B shares and which will participate in the profits of the company as from 1 January 2018. The 2018 Capital Increase will be composed of (i) a tax part, (ii) a guaranteed part and (iii) a supplementary part. The maximum amount of the tax part equals approximately EUR 770 per member of the personnel of the company and its Belgian subsidiaries that satisfies the criteria for subscribing to the 2018 Capital Increase (taking into account that the exact amount of the tax part will be determined by dividing EUR 770 by the issue price per share, rounded up to the upper unit). The maximum amount of the guaranteed part depends on the gross monthly wage of the various groups of members of the personnel of the company and its Belgian subsidiaries (for the members of the Management: maximum 2 x their gross monthly wage; for the executives: maximum 1.1 x their gross monthly wage; for the employees: maximum 0.7 x their gross monthly wage with the exception of the fixed index amount). The maximum amount of the supplementary part equals the difference between EUR 5,300,000 and the total amount of the tax and guaranteed parts that are actually subscribed. The Extraordinary General Meeting of Shareholders decides to fix the issue price at a price equal to the average of the closing prices of the last thirty calendar days preceding 25 October 2018, reduced by 16.66%.

2° to increase the capital within the framework of the 2019 Capital Increase with elimination of the preferential subscription right of the existing shareholders in favour of members of the personnel of the company and its Belgian subsidiaries, by a maximum of EUR 700,000, by means of the issue of new class B shares subscribed in cash and fully paid up, which have the same rights and benefits as the existing class B shares and which will participate in the profits of the company as from 1 January 2019. The Extraordinary General Meeting of Shareholders decides to fix the issue price at a price equal to the average of the closing prices of the last thirty calendar days preceding 31 January 2019, reduced by 16.66%. The maximum amount of the 2019 Capital Increase equals the maximum tax advantage that a member of the personnel will be able to enjoy in the tax declaration of 2020 (revenues 2019), multiplied by 80% of the total number of members of the personnel of the company and its Belgian subsidiaries that satisfy the criteria for subscribing to the 2019 Capital Increase, with an absolute maximum of EUR 700,000. If the amount of the maximum tax advantage has not yet been determined on 31 January 2019, an amount of approximately EUR 770 will be applied per member of the personnel of the company and its Belgian subsidiaries (taking into account that the exact amount of the tax part will be determined, either by the new amount of the maximum tax advantage for revenues year 2019, either by dividing EUR 770 by the issue price per share, rounded up to the upper unit).

The Extraordinary General Meeting of Shareholders decides that the shares to be issued within the framework of the 2018 Capital Increase and within the framework of the 2019 Capital Increase are non-transferable for a term of two years after their respective issues. The Extraordinary General Meeting of Shareholders decides that, if the 2018 Capital Increase and the 2019 Capital Increase are not fully placed, the capital will be increased by the amount of the placed subscriptions.

1. Power of attorney regarding the Capital Increases mentioned in item 2 of the agenda.

Proposed resolution: the Extraordinary General Meeting of Shareholders resolves to grant power of attorney to two directors, acting jointly, (i) to fix the issue price of the 2018 Capital Increase in accordance with the formula mentioned under item 2.1° of the agenda, (ii) to fix the issue price of the 2019 Capital Increase in accordance with the formula mentioned under item 2.2° of the agenda, (iii) to fix the number of shares to be issued, the criteria for subscription by the personnel of the company and its Belgian subsidiaries and the periods for subscription, both for the 2018 Capital Increase and for the 2019 Capital Increase, on the basis of the report of the Board of Directors mentioned in item 1 of the agenda and (iv) to procure recording of complete or partial realization of the 2018 and 2019 Capital Increases in two notarial deeds and to adjust the articles of association accordingly.

Establishment of a strategic committee

1. Introduction of a new article sixteen bis in the articles of association of the company in order to establish a strategic committee as an advisory committee to the board of directors;

Proposed resolution: the Extraordinary General Meeting of Shareholders decides to insert the next article in the articles of association as article 16bis:

"16bis.1 The board of directors can set up a strategic committee, composed of at least three (3) and maximum five (5) non-executive directors. This strategic committee, which has an advisory role, is in charge of drawing up recommendations for the board of directors regarding strategy.

16bis.2 The board of directors, in concertation with the strategic committee, shall draw up the internal rules setting out, inter alia, the rules with respect to the functioning of the strategic committee and the way in which it reports."

1. Determination of the remuneration of the members of the strategic committee in accordance with the remuneration policy as determined by the Ordinary General Meeting of Shareholders of 17 May 2016;

Proposed resolution: the Extraordinary General Meeting of Shareholders decides that the members of the strategic committee will not be remunerated, with the exception of the Chairman, who will be remunerated in the same way as the Chairmen of the other advisory committees of the board of directors.

Abolition of the VVPR-strips

1. Abolition of the VVPR-strips

Proposed resolution: the Extraordinary General Meeting of Shareholders notes that the VVPR-strips have become without value or object since 2013 in view of the amended Belgian tax law (programme act of 27 December 2012). The Extraordinary General Meeting of Shareholders therefore decides on the formal abolition of all VVPR-strips (ISIN Code BE0005597688) issued by the company in the past. The board of directors is granted power of attorney to take all the necessary steps in order to give complete execution to this abolition of the VVPR-strips.
