(a) Savings banks organized under this chapter shall amend their certificates of incorporation by and under this section.
(b) Any savings bank may, from time to time, when and as desired, amend its certificate of incorporation relating to the regulation and governance of corporations established under Title 8, where the same are not inconsistent with the express provisions of this chapter, including, but not limited to, addition to its corporate powers and purposes or diminution thereof, or both (provided such additional corporate power or purpose to be such as is authorized or contemplated under any of the provisions of this chapter); or, if organized as a stock corporation, by increasing or decreasing its authorized capital stock (provided that such increase or decrease be expressly approved by the State Bank Commissioner, and provided also that the capital stock shall not be reduced below the amount prescribed by § 1645 of this title as capital stock for a corporation organized under this chapter); by changing the number or par value of its shares of stock; or by changing its corporate title; and by increasing or decreasing its number of directors (provided that in no case shall the whole number of directors be less than 5). Any or all such changes or alterations may be effected by 1 certificate of amendment. No amendment shall contain a provision which would not have been lawful and proper to insert in an original certificate of incorporation granted or issued under this chapter. In the case of an increase of capital stock, the amendment may provide that the increased stock may, in whole or in part, be disposed of without being offered to the stockholders, but in no case shall any stock be issued except upon payment in full in cash.
(c) The procedure for amendment and the manner of making and effecting the same shall be as prescribed in Chapter 1 of Title 8 for the amendment of the certificate of incorporation of a corporation. No certificate of amendment shall be received or filed by the Secretary of State or be deemed or held to be effective unless and until the proposed certificate of amendment shall have been submitted to the State Bank Commissioner and shall have been approved both in substance and in form by the Commissioner.
