175. Each institution shall assume the defence of any member of its board of directors who is prosecuted by a third person for an act done in the performance of his duties.
In penal or criminal proceedings, however, the institution shall assume the payment of the expenses of a member of the board of directors only where he had reasonable grounds to believe that his conduct was in conformity with the law, or if he has been freed or acquitted or if the proceedings have been withdrawn or dismissed.
