(2) "Equity shares" means shares of any class, whether or not preferred as to dividends or assets, which have unlimited dividend rights.

(3) "Voting rights" means the right to vote for the election of one or more directors, excluding a right so to vote which is dependent on the happening of an event specified in the certificate of incorporation which would change the voting rights of any class of shares.

(5) "Preemptive right" means the right to purchase shares or other securities to be issued or subjected to rights or options to purchase, as such right is defined in this section.

(b) (1) With respect to any corporation incorporated prior to the effective date of subparagraph (2) of this paragraph, except as otherwise provided in the certificate of incorporation, and except as provided in this section, the holders of equity shares of any class, in case of the proposed issuance by the corporation of, or the proposed granting by the corporation of rights or options to purchase, its equity shares of any class or any shares or other securities convertible into or carrying rights or options to purchase its equity shares of any class, shall, if the issuance of the equity shares proposed to be issued or issuable upon exercise of such rights or options or upon conversion of such other securities would adversely affect the unlimited dividend rights of such holders, have the right during a reasonable time and on reasonable conditions, both to be fixed by the board, to purchase such shares or other securities in such proportions as shall be determined as provided in this section.

(2) With respect to any corporation incorporated on or after the effective date of this subparagraph, the holders of such shares shall not have any preemptive right, except as otherwise expressly provided in the certificate of incorporation.

(d) The preemptive right provided for in paragraphs (b) and (c) shall entitle shareholders having such rights to purchase the shares or other securities to be offered or optioned for sale as nearly as practicable in such proportions as would, if such preemptive right were exercised, preserve the relative unlimited dividend rights and voting rights of such holders and at a price or prices not less favorable than the price or prices at which such shares or other securities are proposed to be offered for sale to others, without deduction of such reasonable expenses of and compensation for the sale, underwriting or purchase of such shares or other securities by underwriters or dealers as may lawfully be paid by the corporation. In case each of the shares entitling the holders thereof to preemptive rights does not confer the same unlimited dividend right or voting right, the board shall apportion the shares or other securities to be offered or optioned for sale among the shareholders having preemptive rights to purchase them in such proportions as in the opinion of the board shall preserve as far as practicable the relative unlimited dividend rights and voting rights of the holders at the time of such offering. The apportionment made by the board shall, in the absence of fraud or bad faith, be binding upon all shareholders.

(e) Unless otherwise provided in the certificate of incorporation, shares or other securities offered for sale or subjected to rights or options to purchase shall not be subject to preemptive rights under paragraph (b) or (c) of this section if they:

(1) Are to be issued by the board to effect a merger or consolidation or offered or subjected to rights or options for consideration other than cash;

(f) Shareholders of record entitled to preemptive rights on the record date fixed by the board under section 604 (Fixing record date), or, if no record date is fixed, then on the record date determined under section 604, and no others shall be entitled to the right defined in this section.

(g) The board shall cause to be given to each shareholder entitled to purchase shares or other securities in accordance with this section, a notice directed to him in the manner provided in section 605 (Notice of meetings of shareholders) setting forth the time within which and the terms and conditions upon which the shareholder may purchase such shares or other securities and also the apportionment made of the right to purchase among the shareholders entitled to preemptive rights. Such notice shall be given personally or by mail at least fifteen days prior to the expiration of the period during which the shareholder shall have the right to purchase. All shareholders entitled to preemptive rights to whom notice shall have been given as aforesaid shall be deemed conclusively to have had a reasonable time in which to exercise their preemptive rights.

(h) Shares or other securities which have been offered to shareholders having preemptive rights to purchase and which have not been purchased by them within the time fixed by the board may thereafter, for a period of not exceeding one year following the expiration of the time during which shareholders might have exercised such preemptive rights, be issued, sold or subjected to rights or options to any other person or persons at a price, without deduction of such reasonable expenses of and compensation for the sale, underwriting or purchase of such shares by underwriters or dealers as may lawfully be paid by the corporation, not less than that at which they were offered to such shareholders. Any such shares or other securities not so issued, sold or subjected to rights or options to others during such one year period shall thereafter again be subject to the preemptive rights of shareholders.

(i) Except as otherwise provided in the certificate of incorporation and except as provided in this section, no holder of any shares of any class shall as such holder have any preemptive right to purchase any other shares or securities of any class which at any time may be sold or offered for sale by the corporation. Unless otherwise provided in the certificate of incorporation, holders of bonds on which voting rights are conferred under section 518 shall have no preemptive rights.
