N.J. Stat. Ann. § 17:9A-27.52

In order to have shares of its capital stock available for the purposes of this act, a bank may provide in its certificate of incorporation, or an amendment thereof, for authorized but unissued shares of its capital stock. An amendment of the certificate of incorporation for such purpose shall be made in the manner provided by Article 19 of the act of which this act is a supplement. Such authorized but unissued shares of capital stock of the bank shall not become issued and fully paid shares of the capital stock of the bank until the option or options to which the shares of stock are subject have been exercised, and such shares of capital stock shall not become part of the capital stock of the bank except for the purposes hereof until such time as such shares of stock have been issued and paid for in cash.
