15 Pa. C.S. § 3305
(a) Amendment.--A benefit corporation may terminate its status as a benefit corporation and cease to be subject to this chapter by amending its articles to delete the provision required under section 3304 (relating to election of an existing business corporation to become a benefit corporation) to be stated in the articles of a benefit corporation. The amendment shall not be effective unless it is adopted by at least the minimum status vote.
(b) Fundamental transactions.--If a plan would have the effect of terminating the status of a business corporation as a benefit corporation, the plan shall not be effective unless it is adopted by at least the minimum status vote. Any sale, lease, exchange or other disposition of all or substantially all of the assets of a benefit corporation, unless the transaction is in the usual and regular course of business, shall not be effective unless the transaction is approved by at least the minimum status vote.
