The articles of a corporation may also authorize the board of directors to determine the number, which may be unlimited, of shares in each series of a class of shares, and the designation, rights and restrictions attaching to the shares of each such series.
Before issuing shares of such a series, the board of directors amends the articles of the corporation without shareholder authorization to include the designation of the series and the number of shares it comprises and to set out the rights and restrictions attaching to the shares of the series. The board of directors authorizes a director or an officer of the corporation to sign the articles of amendment.
