Any individual or entity, acting individually or jointly, who acquires a number of shares representing a proportion of the capital or of voting rights equal to or exceeding 1% of the share capital, or any multiple of this percentage, even beyond the minimum declaration limits laid down by the legal and regulatory provisions, must inform the company of the total number of shares and voting rights held by the individual or entity and also of any securities giving future access to the  capital or voting rights which may potentially be attached.

Article 8 - Conveyance and transfer of shares  The shares are freely negotiable.

A double voting right is assigned to each registered share that is paid for in full and that has been registered in the name of the same shareholder for at least two years.  The double vote ceases automatically for any share converted into a bearer share or transferred from one owner to another, subject to exceptions laid down by law. Bonus shares arising from an increase of share capital by incorporation of reserves, profits or share premiums receive the benefit of the double vote as from the time of their issue in so far as they have been assigned on the basis of shares already benefiting from this right.  Article 10 - Paying-up (libération) of shares  Sums that are due on shares to be paid for in cash are requested by the Board of Directors which determines the dates and extent of the calls for funds.
