(a) Each director, before assuming office, shall take an oath or affirmation that he will diligently and honestly perform his duties in the administration of the affairs of the bank or trust company, that he will not permit a willful violation of law by the bank or trust company, and that he meets the eligibility requirements of this chapter and of the articles and bylaws.

(b) A copy of the oath shall be signed by each director and shall be placed into the minutes of the meetings of the directors. No director shall be authorized to participate in the affairs of the board or receive any compensation for service as a director until the oath has been executed by such director. Any person seeking to act in the capacity of a director before subscribing to the oath and otherwise qualifying for service pursuant to the bylaws of the bank or the laws and regulations governing the operations of the bank shall be fully liable for his actions to the same extent as if that person had qualified to serve as a bank director.
