6,166,146 shares of CMS Energy Corporation Common Stock, par value $.01 per
share ("CMS Energy Common Stock"), for all issued and outstanding shares of its
CMS Energy Class G Common Stock, no par value per share ("Class G Common
Stock"), in accordance with its Restated Articles of Incorporation. CMS Energy
