(1) A provision treating a corporation's indemnification of or advance for expenses to directors that is contained in its articles of incorporation, its bylaws, a resolution of its members or board of directors, a contract, or other instrument is valid only if and to the extent the provision is consistent with 35-2-446 through 35-2-454.
