(2) Article III, Section 4 - To align the notice requirement for regular stockholders’ meetings with Section 49 of the RCC, which provides for at least 21 day-notice for regular meetings. (3) Article III, Section 7 - To align the By-Laws with Section 57 of the RCC, which establishes the five-year limit on proxy validity. (4) Article V, Sections 1 and 2 – To align Article V more clearly with the RCC and to clarify the scope and limitations of the authority that may be delegated by the Board to the duly constituted committees. (5) Article VI, Section 1 - To ensure consistency among the provisions on corporate officers by expressly including the Assistant Secretary and Assistant Treasurer among those who may be elected or appointed by the Board of Directors, as already contemplated under Article VI, Sections 11 and 13 of the By-Laws.
