Such resolutions may also provide that, at any time before the validation effective time in respect of any defective corporate act set forth therein, notwithstanding the approval of the ratification of such defective corporate act by stockholders, the board of directors may abandon the ratification of such defective corporate act without further action of the stockholders. The quorum and voting requirements applicable to the ratification by the board of directors of any defective corporate act shall be the quorum and voting requirements applicable to the type of defective corporate act proposed to be ratified at the time the board adopts the resolutions ratifying the defective corporate act; provided that if the certificate of incorporation or bylaws of the corporation, any plan or agreement to which the corporation was a party or any provision of this title, in each case as in effect as of the time of the defective corporate act, would have required a larger number or portion of directors or of specified directors for a quorum to be present or to approve the defective corporate act, such larger number or portion of such directors or such specified directors shall be required for a quorum to be present or to adopt the resolutions to ratify the defective corporate act, as applicable, except that the presence or approval of any director elected, appointed or nominated by holders of any class or series of which no shares are then outstanding, or by any person that is no longer a stockholder, shall not be required.
In the absence of actual fraud in the transaction, the judgment of the board of directors that shares of stock are valid stock or putative stock shall be conclusive, unless otherwise determined by the Court of Chancery in a proceeding brought pursuant to § 205 of this title.
