"VOTING RIGHTS.  Any securities held in the investment funds, including the Employer stock fund (within the meaning of Section 5.1), the Pfizer stock fund (within the meaning of Section 7.1), and the Zoetis stock fund (within the meaning of Section 7.1) shall be voted in the manner provided in the Trust Agreement."
