If the articles of incorporation or the bylaws so provide, the board of directors, by resolution adopted by a majority of the directors in office, may designate and appoint one or more committees each of which shall consist of two or more directors. The committees, to the extent provided in the resolution, in the articles of incorporation or in the bylaws of the corporation, shall have and exercise all the authority of the board of directors, except that no committee shall have the authority of the board of directors in reference to amending, altering or repealing the bylaws; electing, appointing or removing any member of any committee or any director or officer of the corporation; amending the articles of incorporation, restating articles of incorporation, adopting a plan of merger or adopting a plan of consolidation with another corporation; authorizing the sale, lease, exchange or mortgage of all or substantially all of the property and assets of the corporation; authorizing the voluntary dissolution of the corporation or revoking proceedings therefor; adopting a plan for the distribution of the assets of the corporation; or amending, altering or repealing any resolution of the board of directors which by its terms provides that it shall not be amended, altered or repealed by the committee. The designation and appointment of any committee and the delegation thereto of authority shall not operate to relieve the board of directors, or any individual director, of any responsibility imposed upon it or him by law.
