    (a) If the restated articles of incorporation merely restate and integrate, but do not further amend the articles of incorporation as previously amended, the board may adopt the restated articles of incorporation without a vote of the shareholders or members, or the shareholders or members may adopt them, in which case the procedure and vote required under section 611(3) are applicable.

    (b) If the restated articles of incorporation restate, integrate, and also further amend the articles of incorporation, but those amendments include only amendments adopted under section 611(1)(b) or (2), the board may adopt the restated articles of incorporation without a vote of the shareholders or members.

    (c) If the restated articles of incorporation restate and integrate and also further amend in any material respect the articles of incorporation, as previously amended, in a way that is not previously addressed under this section, a vote of the shareholders, members, or directors under section 611(3) is required to adopt restated articles of incorporation.

    (4) An amendment that is adopted in connection with the restatement of the articles of incorporation is subject to any other provision of this act, not inconsistent with this section, that would apply if a certificate of amendment were filed to effect that amendment.
