An amendment, to the extent that it alters an existing provision of the certificate of incorporation or adds a provision not theretofore included in the certificate of incorporation, shall contain only such provision as it would be lawful and proper to insert in an original certificate of incorporation made at the time of the filing of such amendment; except that, when the amendment is made to increase the capital stock of a bank created prior to the effective date of this act, such amendment may be made notwithstanding that the amount of such capital stock as increased will be less than the amount required on original incorporation of a bank as specified in section 4.
