(a) Amendment.--An existing business corporation may become a benefit corporation by amending its articles so that they contain, in addition to the requirements of section 1306(a) (relating to articles of incorporation), a statement that the corporation is a benefit corporation. The amendment shall not be effective unless it is adopted by at least the minimum status vote.

(b) Fundamental transactions.--If an association that is not a benefit corporation is a party to a merger or division or is the exchanging association in an interest exchange, and the surviving, new or any resulting association in the merger, division or interest exchange is to be a benefit corporation, then the plan of merger, division or interest exchange shall not be effective unless it is adopted by the association by at least the minimum status vote.
