(a) Antitakeover provisions.--A transaction under this chapter to which a registered corporation is a party may not impair any right or obligation that a person has under, and may not make applicable to the corporation, any provision of section 2538 (relating to approval of transactions with interested shareholders) or Subchapters E (relating to control transactions), F (relating to business combinations), G (relating to control-share acquisitions), H (relating to disgorgement by certain controlling shareholders following attempts to acquire control), I (relating to severance compensation for employees terminated following certain control-share acquisitions) and J (relating to business combination transactions - labor contracts) of Chapter 25, nor shall it change the standard of care applicable to the directors under Subchapter B of Chapter 17 (relating to fiduciary duty) unless:

(1) If the corporation does not survive the transaction, the transaction satisfies any requirements of the provision.

(2) If the corporation survives the transaction, the approval of the transaction is by a vote of the shareholders or directors which would be sufficient to impair the right or obligation under or make the corporation subject to the provision.

(b) Transitional provision.--

(1) This subsection applies to a transaction of a type authorized by this chapter if:

(i) prior to July 1, 2015, a step has been taken to effectuate the transaction; but

(ii) the transaction does not take effect by July 1, 2015.

(2) Except as set forth in paragraph (3), the transaction shall remain subject to the former provisions of law supplied by this chapter until the transaction:

(i) is abandoned; or

(ii) takes effect.

(3) Notwithstanding paragraph (2), if the plan provides that this chapter applies to the transaction, this chapter shall apply to the transaction after June 30, 2015.
