Before any corporation shall issue any shares of stock of any class or of any series of any class of which the voting powers, designations, preferences and relative, participating, optional or other rights, if any, or the qualifications, limitations or restrictions thereof, if any, shall not have been set forth in the articles of incorporation or in any amendment thereto but shall be provided for in a resolution or resolutions adopted by the board of directors pursuant to authority expressly vested in it by the provisions of the articles of incorporation or an amendment thereto, a certificate setting forth a copy of such resolution or resolutions and the number of shares of stock of such class or series shall be made under the seal of the corporation and signed by the president or a vice-president and by the secretary or an assistant secretary of the corporation and acknowledged by such president or vice-president before an officer authorized by the laws of the United States Virgin Islands to take acknowledgments and shall be filed and indexed in the same manner as articles of incorporation are required to be filed and indexed by the provisions of section 3 of this title. Unless otherwise provided in any such resolution or resolutions, the number of shares of stock of any such class or series so set forth in such resolution or resolutions may be increased or decreased (but not below the number of shares thereof then outstanding) by a certificate likewise made, signed, filed and indexed setting forth a statement that a specified increase or decrease therein had been authorized and directed by a resolution or resolutions likewise adopted by the board of directors. In case the number of such shares shall be so decreased, the number of shares so specified in the certificate shall resume the status which they had prior to the adoption of the first resolution or resolutions.
