MEETINGS OF STOCKHOLDERS

SECTION 10. Notice of Stockholder Business; Nominations.

(a) Annual Meeting of Stockholders.

(i) Nominations of persons for election to the Board at an annual meeting and the proposal of any other business to be considered by the stockholders at an annual meeting shall be made solely (A) as specified in the Corporation’s notice of such meeting (or any supplement thereto), (B) otherwise by or at the direction of the Board (or any duly authorized committee thereof), or (C) by any stockholder of the Corporation that was a stockholder of record at the time of giving the notice provided for in this Section 10, who is entitled to vote at such meeting and who complies with the notice procedures set forth in this Section 10.

(ii) For nominations for director or any other business to be properly brought before an annual meeting by a stockholder pursuant to clause (C) of subparagraph (a)(i) of this Section 10, the stockholder must have given timely notice thereof in writing to the Secretary of the Corporation, and such proposed business, other than nominations of persons for election to the Board, must constitute a proper matter for stockholder action. To be timely, a stockholder’s notice must be delivered to the Secretary at the principal executive offices of the Corporation not later than the close of business on the ninetieth day, nor earlier than the close of business on the one hundred twentieth day, prior to the anniversary of the next preceding annual meeting; provided, however, that in the event that the date of the annual meeting is more than 30 days before or after such anniversary date, to be timely notice by the stockholder must be so delivered not later than the close of business on the tenth day following the day on which public announcement of the date of such meeting is first made by the Corporation. In no event shall an adjournment or postponement of a meeting, or the public announcement thereof, commence a new time period (or extend any time period) of the giving of a stockholder’s notice as described above. Such stockholder’s notice shall set forth: (A) 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 Regulation 14A under the Securities Exchange Act of 1934, as amended (the “Exchange Act”), including such person’s written consent to being named in the proxy statement as a nominee and to serving as a director if elected; (B) as to any other business that the stockholder proposes to bring before the meeting, a brief description of the business desired to be brought before the meeting and the reasons for conducting such business at such meeting, the text of the proposal or business (including the text of any resolutions proposed for consideration and in the event that such business includes a proposal to amend the Bylaws of the Corporation, the language of the proposed amendment), the reasons for conducting such business at the meeting and any material interest in such business of such stockholder and the beneficial owner, if any, on whose behalf the proposal is made; and (C) as to the stockholder giving the notice and the beneficial owner, if any, on whose behalf the nomination or proposal is made (1) the name and address of such stockholder, as they appear on the Corporation’s books and records, and of such beneficial owner, (2) the class or series and number of shares of capital stock of the Corporation that are, directly or indirectly, owned beneficially and held of record by such stockholder and such beneficial owner, (3) any option, warrant, convertible security, stock appreciation right, or similar right with an exercise or conversion privilege or a settlement payment or mechanism at a price related to any class or series of shares of the Corporation or with a value derived in whole or in part from the value of any class or series of shares of the Corporation, whether or not such instrument or right shall be subject to settlement in the underlying class or series of capital stock of the Corporation or otherwise (a “Derivative Instrument”) directly or indirectly owned beneficially by such stockholder or beneficial owner and any other direct or indirect opportunity to profit or share in any profit derived from any increase or decrease in the value of shares of the Corporation, (4) any proxy, contract, arrangement, understanding, or relationship pursuant to which such stockholder or beneficial owner has a right to vote any shares of any security of the Corporation, (5) any short interest of such stockholder or beneficial owner in any security of the Corporation (for purposes of this Bylaw a person shall be deemed to have a short interest in a security if such person directly or indirectly, through any contract, arrangement, understanding, relationship or otherwise, has the opportunity to profit or share in any profit derived from any decrease in the value of the subject security), (6) any rights to dividends on the shares of the Corporation owned beneficially by such stockholder or beneficial owner that are separated or separable from the underlying shares of the Corporation,

(7) any proportionate interest in shares of the Corporation or Derivative Instruments held, directly or indirectly, by a general or limited partnership in which such stockholder or beneficial owner is a general partner or, directly or indirectly, beneficially owns an interest in a general partner, (8) any performance-related fees (other than an asset-based fee) that such stockholder or beneficial owner is entitled to based on any increase or decrease in the value of shares of the Corporation or Derivative Instruments, if any, as of the date of such notice, including without limitation any such interests held by members of such stockholder’s or beneficial owner’s immediate family sharing the same household (which information shall be supplemented by such stockholder and beneficial owner not later than 10 days after the record date for the meeting to disclose such ownership as of the record date), (9) any other information relating to such stockholder and beneficial owner that would be required to be disclosed in a proxy statement or other filings required to be made in connection with solicitations of proxies for, as applicable, the proposal and/or for the election of directors in a contested election pursuant to Section 14 of the Exchange Act and the rules and regulations promulgated thereunder, (10) a representation that the stockholder is a holder of record of stock of the Corporation entitled to vote at such meeting and intends to appear in person or by proxy at the meeting to propose such business or nomination, (11) a description of all agreements, arrangements or understandings between such stockholder and beneficial owner, if any, and any other Person or Persons (including their names) in connection with the proposal of such business by such stockholder and any material interest of such stockholder in such business, and (12) a representation whether the stockholder or the beneficial owner, if any, intends, or is, or intends to be part of a group that intends (x) to deliver a proxy statement and/or form of proxy to holders of at least the percentage of the Corporation’s outstanding capital stock required to approve or adopt the proposal or elect the nominee and/or (y) otherwise to solicit proxies from stockholders in support of such proposal or nomination. The Corporation may require any proposed nominee to furnish such other information as it may reasonably require to determine the eligibility of such proposed nominee to serve as a director of the Corporation.

(iii) Anything in the second sentence of subparagraph (a)(ii) of this Section 10 to the contrary notwithstanding, in the event that the number of directors to be elected to the Board is increased and there is no public announcement by the Corporation naming all the nominees for director or specifying the size of the increased Board at least 100 days prior to the first anniversary of the preceding year’s annual meeting, a stockholder’s notice required by this Section 10 shall also be considered timely, but only with respect to nominees for any new positions created by such increase, if it shall be delivered to the Secretary of the Corporation at the principal executive office of the Corporation not later than the close of business on the tenth day following the day on which such public announcement is first made by the Corporation.

(b) Special Meetings of Stockholders. Only such business shall be conducted at a special meeting of stockholders as shall have been brought before the meeting pursuant to the Corporation’s notice of such meeting. Nominations of persons for election to the Board may be made at a special meeting of stockholders at which directors are to be elected pursuant to the Corporation’s notice of such meeting solely (i) by or at the direction of the Board of Directors or (ii) provided that the Board has determined that directors shall be elected at such meeting, by any stockholder of the Corporation that was a stockholder of record at the time of giving the notice provided for in this Section 10, who shall be entitled to vote at the meeting and who complies with the notice procedures set forth in this Section 10. In the event the Corporation calls a special meeting of stockholders for the purpose of electing one or more directors to the Board, any such stockholder entitled to vote in such election of directors may nominate a person or persons (as the case may be), for election to such positions as specified in the Corporation’s notice of meeting, if the stockholder’s notice required by subparagraph (a)(ii) of this Section 10 shall be delivered to the Secretary of the Corporation at the principal executive offices of the Corporation not earlier than the one hundred twentieth day prior to such special meeting and not later than the close of business on the later of the ninetieth day prior to such special meeting or the tenth day following the day on which public announcement is first made of the date of the special meeting and of the nominees proposed by the Board to be elected at such meeting. In no event shall the public announcement of an adjournment or postponement of a special meeting commence a new time period (or extend any time period) of the giving of a stockholder’s notice as described above.

(c) General.

(i) Only such persons who are nominated in accordance with the procedures set forth in this Section 10 shall be eligible to serve as directors and only such business shall be conducted at a meeting of stockholders as shall have been brought before the meeting in accordance with the procedures set forth in this Section 10. Except as otherwise provided by law or these Bylaws, the chairman of the meeting shall have the power and duty to finally determine whether a nomination or any business proposed to be brought before the meeting was made or proposed, as the case may be, in accordance with the procedures set forth in this Section 10 and, if any proposed nomination or business is not in compliance herewith, to declare that such defective proposal or nomination shall be disregarded.

(ii) For purposes of this Section 10, the term “public announcement” shall mean disclosure in a press release reported by the Dow Jones News Service, Associated Press or comparable national news service or in a document publicly filed by the Corporation with the Securities and Exchange Commission pursuant to Section 13, 14 or 15(d) of the Exchange Act, and the meaning of the term “group” shall be within the meaning ascribed to such term under Section 13(d)(3) of the Exchange Act.

(iii) Notwithstanding the foregoing provisions of this Section 10, a stockholder shall also comply with all applicable requirements of the Exchange Act and the rules and regulations thereunder with respect to the matters set forth in this Section 10. Nothing in this Section 10 shall be deemed to affect any rights of stockholders to request inclusion of proposals in the Corporation’s proxy statement pursuant to Rule 14a-8 under the Exchange Act.
