The Corporation may require any stockholder-proposed nominee to furnish such other information as may reasonably be required by the Corporation to determine the eligibility of such proposed nominee to serve as a director of the Corporation.

(d) Derivative and Short Information. “Derivative and Short Information” shall mean a description of any agreement, arrangement or understanding (including without limitation, any derivative or short positions, profit interests, options, hedging transactions, and borrowed or loaned shares) that has been entered into as of the date of the stockholder’s notice by, or on behalf of, the stockholder or any of its affiliates or associates, the effect or intent of which is to mitigate loss to, manage risk or benefit of share price changes for, or provide 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, or increase or decrease the voting power of the stockholder or any of its affiliates or associates with respect to shares of stock of the Company. Thus, for example, Derivative and Short Information, includes without limitation, 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 directly or indirectly owned beneficially by such stockholder or any of its affiliates or associates.

such information is available only to stockholders of the Corporation. If the meeting is to be held at a place, then the list shall be produced and kept at the time and place of the meeting during the whole time thereof, and may be inspected by any stockholder who is present. If the meeting is to be held solely by means of remote communication, then the list shall also be open to the examination of any stockholder during the whole time of the meeting on a reasonably accessible electronic network, and the information required to access such list shall be provided with the notice of the meeting.

2.7 Organization and Conduct of Business. The Chairman of the Board or, in his or her absence, the Lead Director, or in his or her absence, the Chief Executive Officer of the Corporation or, in their absence, such person as the Board may have designated or, in the absence of such a person, such person as may be chosen by the holders of a majority of the stocks entitled to vote who are present, in person or by proxy, shall call to order any meeting of the stockholders and act as Chairman of the meeting. In the absence of the Secretary of the Corporation, the Secretary of the meeting shall be such person as the Chairman appoints.

The Chairman of any meeting of stockholders shall determine the order of business and the procedure at the meeting, including such regulation of the manner of voting and the conduct of discussion as seems to him or her in order.

Except where otherwise provided by law or in the Amended and Restated Certificate of Incorporation or these By-laws, the holders of a majority of the stock issued and outstanding and entitled to vote, present in person or represented in proxy, shall constitute a quorum at all meetings of the stockholders. The chairman of the meeting or a majority of the stockholders entitled to vote at the meeting, present in person or represented by proxy, shall have power to adjourn the meeting from time to time, without notice other than announcement at the meeting. At such adjourned meeting at which a quorum is present or represented, any business may be transacted which might have been transacted at the meeting as originally noticed.

2.9 Voting Rights. Except as may be provided in the Amended and Restated Certificate of Incorporation, each stockholder shall at every meeting of the stockholders be entitled to one vote in person or by proxy for each share of the capital stock having voting power held by such stockholder as there is no right to cumulate votes in the election of directors.

In the election of directors, no stockholder shall be entitled to vote in favor of any candidate unless such candidate’s names have been placed in nomination prior to the voting. In any election of directors, the candidates receiving the highest number of affirmative votes of the shares entitled to be voted for them, up to the number of directors to be elected by such shares, are elected. Votes against a director and votes withheld shall have no legal effect.

Voting may be by voice or ballot, provided that any election of directors must be by ballot upon the demand of any stockholder made at the meeting and before the voting begins.

2.11 Record Date for Stockholder Notice and Voting.

(a) In order that the Corporation may determine the stockholders entitled to notice of or to vote at any meeting of stockholders or any adjournment thereof, the Board may fix a record date, which record date shall not precede the date upon which the resolution fixing the record date is adopted by the Board, and which record date shall not be more than sixty or fewer than ten days before the date of such meeting. If no record date is fixed by the Board, the record date for determining stockholders entitled to notice of or to vote at any meeting of stockholders or any adjournment thereof shall be at the close of business on the day next preceding the day on which notice is given, or, if notice is waived, at the close of business on the day next preceding the day on which the meeting is held.

Such record date shall not precede the date upon which the resolution fixing such record date is adopted, and shall not be more than sixty days prior to such action. If no record date is fixed, the record date for determining stockholders for any such purpose shall be the close of business on the day on which the Board adopts the resolution relating thereto.

the stockholder’s attorney-in-fact. A validly executed proxy which does not state that it is irrevocable shall continue in full force and effect unless (a) revoked by the person executing it, before the vote pursuant to that proxy, by a writing delivered to the Corporation stating that the proxy is revoked or by a subsequent proxy executed by the maker of the proxy, or by that person’s attendance and vote at the meeting; or (b) written notice of the death or incapacity of the maker of that proxy is received by the Corporation before the vote pursuant to that proxy is counted; provided, however, that no proxy shall be valid after the expiration of eleven months from the date of the proxy, unless otherwise provided in the proxy.

2.13 Inspectors of Election. Before any meeting of stockholders, the Board may appoint any person other than nominees for office to act as inspectors of election at the meeting or its adjournment. If no inspectors of election are so appointed, the Chairman of the meeting may, and on the request of any stockholder or a stockholder’s proxy shall, appoint inspectors of election at the meeting. The number of inspectors shall be either one (1) or three (3). If inspectors are appointed at a meeting on the request of one or more stockholders or proxies, the holders of a majority of shares or their proxies present at the meeting shall determine whether one (1) or three (3) inspectors are to be appointed. If any person appointed as inspector fails to appear or fails or refuses to act, the Chairman of the meeting may, and upon the request of any stockholder or a stockholder’s proxy shall, appoint a person to fill that vacancy or to act in place of such inspector.

2.14 No Action Without Meeting by Written Consent. The stockholders shall not be entitled to act by written consent; all actions of stockholders are required to be taken at an annual or special meeting.

Directors shall be elected at the annual meeting or at any special meeting of the stockholders, except as provided in Section 3.2 hereof, and each director so elected shall hold office until the expiration of the term for which elected, or until his successor is elected and qualified, or until his earlier resignation or removal. All elections of directors shall be by written ballot, unless otherwise provided in the Amended and Restated Certificate of Incorporation; if authorized by the Board, such requirement of a written ballot shall be satisfied by a ballot submitted by electronic transmission, provided that any such electronic transmission must either set forth or be submitted with information from which it can be determined that the electronic transmission was authorized by the stockholder or proxy holder.

3.2 Resignation and Vacancies.

The stockholders may elect a director or directors at any time to fill any vacancy or vacancies not filled by the directors. If the Board accepts the resignation of a director tendered to take effect at a future time, the Board shall have power to elect a successor to take office when the resignation is to become effective. If there are no directors in office, then an election of directors may be held in the manner provided by statute.

6.2 Indemnification of Others. The Corporation shall have the power, to the maximum extent and in the manner permitted by the General Corporation Law of Delaware, to indemnify each of its employees and agents (other than directors and officers) against expenses (including attorneys’ fees), judgments, fines, settlements and other amounts actually and reasonably incurred in connection with any proceeding, arising by reason of the fact that such person is or was an agent of the Corporation. For purposes of this Section 6.2, an “employee” or “agent” of the Corporation (other than a director or officer) includes any person (a) who is or was an employee or agent of the Corporation, (b) who is or was serving at the request of the Corporation as an employee or agent of another corporation, partnership, joint venture, trust or other enterprise, or (c) who was an employee or agent of a corporation which was a predecessor corporation of the Corporation or of another enterprise at the request of such predecessor corporation.

indemnification is permitted pursuant to Section 6.2 hereof, following authorization thereof by the Board, shall be paid by the Corporation in advance of the final disposition of such action or proceeding upon receipt of an undertaking by or on behalf of the indemnified party to repay such amount, if it shall ultimately be determined that the indemnified party is not entitled to be indemnified as authorized in this Article 6.

6.4 Indemnity Not Exclusive. The indemnification provided by this Article 6 shall not be deemed exclusive of any other rights to which those seeking indemnification may be entitled under any bylaw, agreement, vote of stockholders or disinterested directors or otherwise, both as to action in an official capacity and as to action in another capacity while holding such office, to the extent that such additional rights to indemnification are authorized in the Amended and Restated Certificate of Incorporation.

7.4 Registered Stockholders. The Corporation shall be entitled to recognize the exclusive right of a person registered on its books as the owner of stock to receive dividends, and to vote as such owner, and to hold liable for calls and assessments a percent registered on its books as the owner of stock, and shall not be bound to recognize any equitable or other claim to or interest in such stock on the part of any other person, whether or not it shall have express or other notice thereof, except as otherwise provided by the laws of Delaware.

7.5 Lost, Stolen or Destroyed Certificates. The Board may direct that a new certificate or certificates be issued to replace any certificate or certificates theretofore issued by the Corporation alleged to have been lost, stolen or destroyed, upon the making of an affidavit of that fact by the person claiming the certificate of stock to be lost, stolen or destroyed.
