Each class shall consist of shares that have the designations and relative voting, distribution, liquidation, and other rights, preferences, and limitations, that are consistent with this act, stated in the articles of incorporation or bylaws.

(b) The articles of incorporation or bylaws may deny, limit, or otherwise prescribe the distribution or liquidation rights of shares of any class. Approval by the shareholders and each affected class of shareholders, if any, voting as a class, is required to adopt, amend, or repeal any bylaw denying, limiting, or otherwise prescribing the voting rights of shareholders or the affected class of shareholders.

(c) If the shares are divided into 2 or more classes, the shares of each class shall be designated to distinguish them from the shares of the other classes.

(f) Any of the voting, distribution, liquidation, or other rights, preferences, or limitations of a class may be made dependent on facts or events ascertainable outside of the articles of incorporation or the bylaws, if the manner in which the facts or events operate on the rights, preferences, or limitations is set forth in the articles of incorporation or the bylaws.
