In the absence of such provision, all officers shall be elected or appointed annually by a board of directors. Any 2 or more offices may be held by the same person unless otherwise provided in the articles of incorporation or bylaws.  

2.  Authority to make contracts.  Unless they have reason to believe otherwise, persons dealing with a corporation are entitled to assume that its president has authority to make, on its behalf, all contracts which are within the ordinary course of those activities in which the corporation is already engaged.
