CONTRACTS, PROXIES, ETC.
SECTION 7.1 Contracts. Except as otherwise required by law, the Certificate of Incorporation or these By-Laws, any contracts or other instruments may be executed and delivered in the name and on the behalf of the Corporation by such officer or officers of the Corporation as the Board of Directors may from time to time specify. Such authority may be general or confined to specific instances as the Board of Directors may determine. The Chairman of the Board, the Chief Executive Officer or such other persons as the Board of Directors may authorize may execute bonds, contracts, deeds, leases and other instruments to be made or executed for or on behalf of the Corporation. Subject to any restrictions imposed by the Board of Directors or the Chairman of the Board, the Chief Executive Officer or such other persons as the Board of Directors may authorize may delegate contractual powers to others under his or her jurisdiction, it being understood, however, that any such delegation of power shall not relieve such person of responsibility with respect to the exercise of such delegated power.
SECTION 7.2 Proxies. Unless otherwise provided by resolution adopted by the Board of Directors, the Chairman of the Board, the Chief Executive Officer, the President or any Vice President may from time to time appoint an attorney or attorneys or agent or agents of the Corporation, in the name and on behalf of the Corporation, to cast the votes that the Corporation may be entitled to cast as the holder of stock or other securities in any other entity, any of whose stock or other securities may be held by the Corporation, at meetings of the holders of the stock or other securities of such other entity, or to consent in writing, in the name of the Corporation as such holder, to any action by such other entity, and may instruct the person or persons so appointed as to the manner of casting such votes or giving such consent, and may execute or cause to be executed, in the name and on behalf of the Corporation and under its corporate seal or otherwise, all such written proxies or other instruments as he or she may deem necessary or proper in the premises.
