conversion or exchange of stock or for the purpose of any other lawful action, the Board may fix, in advance, a record date, which shall not be more than sixty (60) nor less than ten (10) days before the date of such meeting, nor more than sixty (60) days prior to any other action.

For purposes of this Section 2.11, any adjournment(s) or postponement(s) of the original meeting shall be deemed for purposes of notice to be a continuation of the original meeting and no business may be brought before any reconvened meeting unless such timely notice of such business was given to the Secretary of the Corporation for the meeting as originally scheduled. A stockholder’s notice to the Secretary shall set forth as to each matter the stockholder proposes to bring before the annual meeting (i) a brief description of the business desired to be brought before the annual meeting, (ii) the name and record address of the stockholder proposing such business, (iii) the class and number of shares of the Corporation which are beneficially owned by the stockholder, and (iv) any material interest of the stockholder in such business. Notwithstanding the foregoing, nothing in this Section 2.11 shall be interpreted or construed to require the inclusion of information about any such proposal in any proxy statement distributed by, at the direction of, or on behalf of the Board.

(b) The chairman of an annual meeting shall, if the business facts warrant, determine and declare to the meeting that business was not properly brought before the meeting in accordance with the provisions of this Section 2.11, and if the chairman should so determine, the chairman shall so declare to the meeting and any such business not properly brought before the meeting shall not be transacted.

For purposes of this Section 2.12, any adjournment(s) or postponement(s) of the original meeting shall be deemed for purposes of notice to be a continuation of the original meeting and no nominations by a stockholder of persons to be elected directors of the Corporation may be made at any such reconvened meeting unless pursuant to a notice which is timely for the meeting on the date originally scheduled. Such stockholder’s notice shall set forth: (i) as to each person whom the stockholder proposes to nominate for election or re-election as a director, all information relating to such person that is required to be disclosed in solicitations of proxies for election of directors, or is otherwise required, in each case pursuant to the Securities Exchange Act of 1934, as amended, (including such person’s written consent to being named in the proxy statement as a nominee and to serving as a director if elected); and (ii) as to the stockholder giving the notice (A) the name and address, as they appear on the Corporation’s books, of such stockholder, and (B) the class and number of shares of the Corporation which are beneficially owned by such stockholder.
