(b) Any person dealing with the Company shall be entitled to rely on a certificate of the Secretary or any Assistant Secretary as conclusive evidence of the incumbency of any Officer and his authority to take action on behalf of the Company and shall be entitled to rely on a copy of any resolution or other action taken by the Committee and certified by any Officer not named in the resolution, as conclusive evidence of such action of the authority of the Officer referred to in such resolution to bind the Company to the extent set forth therein.
