PROPOSALS OF THE BOARD OF DIRECTORS

1. Re-election of the members of the Board of Directors and of the Chairman of the Board of Directors

The Board of Directors proposes the re-election of the following members: Fabien Jordan, Roland Loos, Yves Pillonel and Jonathan Cholak as members of the Board of Directors, and the re-election of José Achache as Chairman of the Board of Directors for a term that will end until completion of the next annual general meeting of the shareholders (pertaining to the business year 2023) (the "AGM").

Note:

Pursuant to article 21 of the Articles of Association, the members of the Board of Directors and the Chairman must be elected individually each year at the AGM, which must as a rule be held within a period of 6 months after the end of the business year (i.e., before June 30, 2024 with respect to the AGM relating to the business year 2023). Considering that the Company is not ready to hold the AGM within the statutory deadline, it is proposed to re-

elect the Board members through an extraordinary general meeting so that the Company will have a duly appointed Board of Directors until the holding of the AGM.

2. Re-election of the Independent Proxy

The Board of Directors proposes to re-elect Mr. Matthieu Sinner, notary, Avenue du Théâtre 7, 1005 Lausanne, Switzerland, as Independent Proxy for a term which will end until completion of the next AGM.

Note:

The rationale of the re-election of the Independent Proxy is the same as for the re-election of the Board of Directors mutatis mutandis.

3. Miscellaneous

Questions of the shareholders will be answered.
