2. (i) the report of the Board of Directors, drawn up in accordance with sections 7:179 and 7:191 of the Code of companies and associations, and the report of the statutory auditors, also drawn up in accordance with the aforementioned sections of the Code of companies and associations, concerning a capital increase in cash with cancellation of the preferential subscription right of the shareholders in favour of the members of the personnel of the company and of its Belgian subsidiaries within the meaning of section 1:15 of the Code of companies and associations, and

3. (ii) the report of the Board of Directors, drawn up in accordance with section 7:155 of the Code of companies and associations, and the report of the statutory auditors, also drawn up in accordance with the aforementioned section of the Code of companies and associations, concerning the amendment of the rights attached to classes of shares;
4. 1. Double capital increase for a total amount of maximum EUR 6,000,000, composed of a first capital increase in 2022 (hereinafter "2022 Capital Increase") with a maximum of EUR 5,000,000 and a second capital increase in 2023 (hereinafter "2023 Capital Increase") with a maximum of EUR 1,000,000 by means of the issue of new class B shares, with cancellation of the preferential subscription right of the existing shareholders, in favour of the members of personnel of the company and of its Belgian subsidiaries;

Proposed resolution: the Extraordinary General Meeting of Shareholders resolves:

1° to increase the capital within the framework of the 2022 Capital Increase with cancellation of the preferential subscription right of the existing shareholders, in favour of members of the personnel of the company and of its Belgian subsidiaries, with a maximum of EUR 5,000,000, 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 2022. The 2022 Capital Increase will be composed of (i) a tax part, (ii) a guaranteed part and (iii) a supplementary part. The amount of the tax part equals approximately EUR 800 per member of the personnel of the company and of its Belgian subsidiaries that satisfies the criteria for subscribing to the 2022 Capital Increase (taking into account that the exact amount of the tax part will be determined by dividing EUR 780 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 of its Belgian subsidiaries (for the members of the management: maximum 2 x the gross monthly wage; for the executives: maximum 1.1 x the gross monthly wage; for the employees: maximum 0.7 x the gross monthly wage with the exception of the fixed index amount). The maximum amount of the supplementary part equals the difference between EUR 5,000,000 and the total amount of the tax and guaranteed parts that are actually subscribed. The Extraordinary General Meeting of Shareholders resolves to fix the issue price at a price equal to the average of the closing prices of the last thirty calendar days preceding 15 October 2022, reduced by 16.66%

2° to increase the capital within the framework of the 2023 Capital Increase with cancellation of the preferential subscription right of the existing shareholders, in favour of members of the personnel of the company and of its Belgian subsidiaries, with a maximum of EUR 1,000,000, 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

⁴ TICK WHAT APPLIES

the existing class B shares and which will participate in the profits of the company as from 1 January 2023. The Extraordinary General Meeting of Shareholders resolves to fix the issue price at a price equal to the average of the closing prices of the last thirty calendar days preceding 6 March 2023, reduced by 16.66%. The maximum amount of the 2023 Capital Increase equals the maximum tax advantage that a member of the personnel will be able to enjoy in the tax declaration of 2024 (revenues 2023), taking into account that the exact amount shall be obtained by dividing EUR 780 by the subscription price per share, rounded up to the nearest unit, multiplied by 80% of the total number of members of the personnel of the company and of its Belgian subsidiaries that satisfy the criteria for subscribing to the 2023 Capital Increase, with an absolute maximum of EUR 1,000,000. If the amount of the maximum tax advantage has not yet been determined on 31 January 2023, the amount applicable for revenues year 2022 will be used, which is EUR 780 at present, so that an amount of approximately EUR 800 will be applied per member of the personnel of the company and of its Belgian subsidiaries for the tax part (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 2021, either by dividing EUR 780 by the issue price per share, rounded up to the upper unit).

The Extraordinary General Meeting of Shareholders resolves that the shares to be issued within the framework of the 2022 Capital Increase and within the framework of the 2023 Capital Increase are non-transferable for a term of two years after their respective issues. The Extraordinary General Meeting of Shareholders resolves that, if the 2022 Capital Increase and the 2023 Capital Increase are not fully placed, the capital will be increased by the amount of the placed subscriptions.
