At the expiration of any term of three (3) years, any director may be re-elected. In any event, each director’s term shall be deemed extended or shortened until such time as his or her successor shall be duly elected and have qualified.

SEVENTH: The duration of the Corporation is to be perpetual.

Such right, power and authority shall include, but not be limited to, amending the Corporation’s by-laws, appointing committees of the Board of Directors, each of which, when duly appointed shall act with the delegated power and authority of the entire Board of Directors to the fullest extent permitted by the Not-For-Profit Corporation Law, establishing classes of membership and the respective rights, designations and preferences, if any, of each such class, determining criteria for membership in the Corporation and in any such class (including determining and/or varying the terms and conditions of any standard agreement between and/or among the Corporation and its members), and setting, amending and/or waiving membership dues generally and with respect to any particular member.

Notwithstanding the foregoing, no indemnification may be made to or on behalf of any director or officer if a judgment or other final adjudication adverse to the director or officer establishes that his or her acts were committed in bad faith or the result of active and deliberate dishonesty and were material to the cause of action so adjudicated, or that he or she personally gained in fact a financial profit or other advantage to which he or she was not legally entitled.
