10. The chairman of the board of directors of the company, under pain of forfeiture of his office, shall not have any direct or indirect interest in an undertaking that puts his personal interest in conflict with that of the company. Such forfeiture is not incurred, however, if such interest devolves to him by succession or gift and he renounces or disposes of it with all possible dispatch.
Any other member of the board of directors having a direct or indirect interest in an undertaking must, under pain of forfeiture of his office, disclose it in writing to the chairman and abstain from participating in any decision dealing with the undertaking in which he has an interest.
