Maximum amount allocated to the share buy-back programme, maximum number and characteristics of shares, maximum purchase price The resolution proposed to the General Meeting provides that Societe Generale may purchase its ordinary shares up to 10% of the total number of shares.

This maximum amount is likely to change in case of transactions impacting its share capital.
