(a)           The Merger shall not become effective until, and shall become effective at, 11:59 p.m. on October 31, 2007; provided that, prior to such time, a certificate of merger shall have been executed and accepted for filing in the office of the Delaware Secretary of State in accordance with the DLLCA specifying such effective time.
