At any one time, each non-Employee Director may receive only one additional annual retainer fee in connection with service as the Chair of a committee (whether in the position of Lead Director, Audit Committee Chair, Compensation and Benefits Committee Chair or Other Committee Chair), regardless of how many committee Chair positions held by such director. For the avoidance of doubt, a non-Employee Director may simultaneously serve as the Chair of more than one committee, but will receive for such service only one additional annual retainer fee, equal to the highest of the additional annual retainer fees associated with his or her Chair positions.
