TEXT OF RESOLUTIONS

First resolution

Creation of a class of preferred shares referred to as “Class A preferred shares” convertible into ordinary shares (the “A Shares”) - determination of the specific rights attached to the A Shares—corresponding amendment to the bylaws

The general meeting, deliberating in accordance with the quorum and majority requirements for extraordinary general meetings,

after having reviewed :

•

the board of directors’ report,

•

the special report of the statutory auditors referred to in Articles L. 228-12 and R. 228-18 of the French Commercial Code,

•

the report of the specially appointed auditor (commissaire aux avantages particuliers)’s on the specific rights attached to preferred shares prepared in accordance with Articles L. 228-15 and L. 225-147 of the French Commercial Code,

•

the draft of the Company’s new bylaws appended to the board of directors’ report to this shareholders’ meeting (the “Revised Bylaws”), which is available free of charge at the registered office and can be consulted on the Company’s website under the heading “General Meeting of [-] 2023”.

•

the approval of the terms of this resolution by each meeting of holders of securities giving access to the Company’s share capital,

subject to the condition subsequent (condition résolutoire) of the non-adoption of the second and the fourth resolutions below,

resolves, in accordance with the provisions of Article L. 228-11 of the French Commercial Code, to create a new class of preferred shares convertible into ordinary shares referred to as “Class A preferred shares” (hereinafter the “A Shares”), the characteristics of which are as follows:

from their date of issuance, the A Shares carry one voting right per A Share at the Company’s shareholders’ general meetings. The A Shares will therefore not be eligible for double voting rights,

no application will be made for the A Shares to be admitted for trading on the Euronext Growth market or any other market on which the Company’s shares (or ADSs or ADRs) may be admitted,

the A Shares will have a par value equal to that of the Company’s ordinary shares, i.e. EUR 0.05,

the A Shares will be held in registered form and may not be transferred to bearer form,

the A Shares will not be transferable except to an “Affiliate” (as this term is defined in the Revised Bylaws) of the holder of A Shares,

the A Shares benefit from a preferential distribution right of the boni in the event of a liquidation of the Company, as described in the Revised Bylaws,

any holder of A Shares may request the conversion of some or all of its A Shares into new ordinary shares of the Company in accordance with the terms and conditions set out in the Revised Bylaws, on the basis of one ordinary share for one A Share (the “Conversion Ratio”),

The new ordinary shares resulting from the conversion of the A Shares will be assimilated to the outstanding ordinary shares and will carry dividend rights as from the first day of the financial year in progress on the date of their conversion, and will confer to their holders, as from their delivery, all the rights attached to ordinary shares. They will be subject to a request for admission for trading on the Euronext Growth market on the same quotation line as the ordinary shares.

The board of directors will acknowledge the conversion of the A Shares into ordinary shares, will acknowledge the number of ordinary shares resulting from the conversion of A Shares and will make the necessary amendments to the bylaws. This power may be delegated to the managing director (Directeur Général) under the conditions provided for by law.

Notwithstanding the foregoing, any A Shares outstanding will automatically convert into ordinary shares on the basis of the Conversion Ratio upon the acquisition by any person of such number of ordinary shares causing such person to hold over ninety (90) per cent of the share capital and voting rights of the Company,

acknowledges that the conversion of the A Shares into ordinary shares results in shareholders waiving their preferential subscription rights to the new ordinary shares resulting from the conversion,

resolves that the specific rights attached to the A Shares are attached to the A Shares and not to their holders, and will therefore benefit to the successive holders of said A Shares,

resolves that in the event of a share capital increase by incorporating reserves and distribution of free shares, distribution of dividends in the form of shares or allocation of free shares, the shares allocated by virtue of the rights attached to the A Shares will themselves be A Shares,

resolves that new shares subscribed to by a shareholder holding A Shares through the exercise of a preferential subscription right will themselves be A Shares, unless otherwise decided by the general meeting authorizing such share capital increase,

specifies, as necessary, that in the event of a reverse stock-split or split of the nominal value of the Company’s shares (or other equivalent transactions), the shares allotted in respect of the A Shares will themselves be A Shares,

specifies that the specific rights attached to A Shares are set out in the Revised Bylaws, which shall form an integral part of this first resolution,

resolves, as a consequence of the foregoing, to amend the Company’s bylaws and to adopt the Articles of the Revised Bylaws relating to the A Shares, as appended to the board of directors’ report to the general meeting.

Second resolution

Delegation of authority to the board of directors to increase the share capital by a maximum nominal amount of EUR 500,000, through the issuance of a maximum of 10,000,000 A Shares, with cancellation of the shareholders’ preferential subscription rights in favor of a named person.

resolves that the issuance price of the A Shares issued under this delegation will be 5 US dollars, the euro equivalent of which will be determined by the board of directors on the date on which the share capital increase is decided,

resolves to issue a maximum of 10,000,000 ordinary shares, representing a maximum par value of EUR 500,000, which may be issued by the Company in the event of conversion of the A Shares in accordance with the terms and conditions set out in the Revised Bylaws,
