187.11. No member of the board of directors may, as part of his duties, perform any act involving expenses chargeable to the Société except with the prior authorization of the board to perform the act and incur, in consequence thereof, expenses not exceeding the amount fixed by the board.
However, the chairman of the board is not required to obtain prior authorization when acting in his capacity as representative of the Société. Such exemption also applies to any other member of the board of directors designated by the chairman to replace him as representative of the Société on any occasion on which neither vice-chairman is able to replace him in accordance with section 177.
