after such transaction).

and the Board shall promptly fill the vacancy with such successor Nominee (it being understood that any such Nominee shall serve the remainder of the term of the director whom such Nominee replaces). 

(g) If a Nominee is not appointed or elected to the Board because of such person’s death, disability, disqualification, withdrawal as a
