Meetings of Stockholders

SECTION 1. Annual Meeting. The annual meeting of stockholders of the Corporation shall be held in each year on the third Wednesday in May, or on such other date as the Board of Directors may designate, and at such time and place as the Board of Directors may designate, for the election of directors and for the transaction of such other business as may properly come before the meeting.

SECTION 2. Special Meetings. Except as provided in the Certificate of Incorporation, special meetings of the stockholders may be called only on the order of the Chairman of the Board, Lead Director, or the Board of Directors and shall be held at such date, time and place as may be specified by such order.

SECTION 3. Election of Directors. Each director to be elected by stockholders shall be elected by the vote of the majority of the votes cast with respect to the director at any meeting for the election of directors at which a quorum is present by the holders of shares present in person or represented by proxy and entitled to vote on the election of directors; provided that if the number of nominees for director exceeds the number of directors to be elected, the directors shall be elected by the vote of a plurality of the shares represented in person or by proxy at any such meeting and entitled to vote on the election of directors. For purposes of this Section 3, a majority of the votes cast means that the number of shares voted “for” a director must exceed 50% of the number of votes cast with respect to that director’s election. Votes cast shall include votes to withhold authority and exclude abstentions with respect to that director’s election. If directors are to be elected by a plurality, stockholders shall be permitted to withhold votes from a nominee but shall not be permitted to vote against a nominee.

If at any meeting for the election of directors a nominee for director who is an incumbent director is not elected and no successor has been elected at such meeting, the director shall promptly tender to the Board his or her offer of resignation as a director. Such resignation shall be made subject to the Board’s acceptance. The Corporate Governance and Nominating Committee shall make a recommendation to the Board as to whether to accept or reject the tendered offer of resignation, or whether other action should be taken. In determining whether to accept or reject the tendered offer of resignation, the Corporate Governance and Nominating Committee shall be entitled to consider all factors believed relevant by the members of such Committee, including without limitation: (1) any stated reason for the director not receiving the required vote and whether the underlying cause or causes are curable, (2) the factors, if any, set forth in the guidelines or other policies that are to be considered by the Corporate Governance and Nominating Committee in evaluating potential candidates for the Board as such factors relate to each director who

has offered his or her resignation, (3) the length of service of such director, (4) the effect of such resignation on the Corporation’s compliance with any law, rule, regulation, stock exchange listing standards or contractual obligations, (5) such director’s contributions to the Corporation, and (6) any other factors that the Corporate Governance and Nominating Committee deems to be in the best interests of the Corporation. No director who has tendered his or her offer of resignation may participate in the Committee’s recommendation. If all of the members of the Corporate Governance and Nominating Committee have tendered their offers of resignation, then the Board shall act on the offers of resignation.

The Board shall act on the tendered offers of resignation, taking into account the recommendation of the Corporate Governance and Nominating Committee, and shall publicly disclose (by press release, a filing with the Securities and Exchange Commission or other broadly disseminated means of communication) its decision regarding the tendered offers of resignation and the rationale behind the decision within 90 days from the date of the certification of the election results. In determining whether to accept or reject any offer of resignation, the Board shall be entitled to consider all of the factors considered by the Corporate Governance and Nominating Committee and any additional information and factors that the Board believes to be relevant. No director who has tendered his or her offer of resignation may participate in the Board’s decision. Notwithstanding the foregoing, if the acceptance by the Board of all of the then pending offers of resignation would result in the Corporation having fewer than a majority of the directors who were in office prior to the applicable election, the Board may elect to extend such 90-day period by an additional 90 days if the Board shall determine that such an extension is in the best interests of the Corporation.

If any incumbent director’s offer of resignation is not accepted by the Board, such director shall continue to serve until the next annual meeting and until his or her successor is duly elected and qualified, subject to such director’s earlier death, resignation, disqualification or removal. If a director’s offer of resignation is accepted by the Board pursuant to this Section 3, or if a nominee for director is not elected and the nominee is not an incumbent director, then the Board, in its sole discretion, may fill any resulting vacancy pursuant to the provisions of Section 223 of the Delaware General Corporation Law or may decrease the size of the Board pursuant to the provisions of the Corporation’s Certificate of Incorporation.

SECTION 4. Notice; Stockholder Nominations and Proposals. Notice, in writing or by electronic transmission, of all meetings of the stockholders, shall be mailed or otherwise given as permitted by the laws of the State of Delaware to each stockholder not less than twenty nor more than sixty days before the meeting. The notice or an accompanying document shall identify the business to be transacted at the meeting and, if directors are to be elected, the candidates therefor, as determined by the Board of Directors. As used in these By-laws, the term “electronic transmission” shall mean any kind of electronic transmission or other form of remote communication that is permitted by the laws of the State of Delaware.

Other business may be transacted at the annual meeting (but not at any special meeting), only if the Secretary of the Corporation has received from the sponsoring stockholder (a) not less than ninety nor more than one hundred twenty days in advance of the date which is the anniversary of the date the Corporation’s proxy statement was released to security holders in connection with the previous year’s annual meeting or, if the date of the applicable annual meeting has been changed by more than thirty days from the date contemplated at the time of the previous year’s proxy statement, not less than ninety days before the date of the applicable annual meeting, a written notice setting forth (i) as to each matter the stockholder proposes to bring before the annual meeting, a brief description of the proposal desired to be brought before the annual meeting and the reasons for conducting such business at the annual meeting, (ii) the name and address, as they appear on the Corporation’s books, of the stockholder proposing such business, (iii) the class and number of shares which are beneficially owned by the stockholder on the date of such stockholder’s notice and (iv) any material interest of the stockholder in such proposal, and (b) not more than ten days after receipt by the sponsoring stockholder of a written request from the Secretary, such additional information as the Secretary may reasonably require. Notwithstanding anything in these By-laws to the contrary, no business shall be brought before or conducted at an annual meeting except in accordance with the provisions of this Section 3. The officer of the Corporation or other person presiding over the annual meeting shall, if the facts so warrant, determine that business was not properly brought before the meeting in accordance with the provisions of this Section 3 and, if he or she should so determine, such officer shall so declare to the meeting and any business so determined to be not properly brought before the meeting shall not be transacted.

Other candidates for director may be nominated at the annual meeting (but not at any special meeting), only if the Secretary of the Corporation has received from the nominating stockholder (a) not less than ninety nor more than one hundred twenty days in advance of the date which is the anniversary of the date the Corporation’s proxy statement was released to security holders in connection with the previous year’s annual meeting or, if the date of the applicable annual meeting has been changed by more than thirty days from the date contemplated at the time of the previous year’s proxy statement, not less than ninety days before the date of the applicable annual meeting, a written notice setting forth (i) with respect to each person whom such 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 (including such person’s written consent to being named in the proxy statement as a nominee and to serving as a director if elected) or any successor regulation or statute, (ii) the name and address, as they appear on the Corporation’s books, of the stockholder proposing such business and (iii) the class and number of shares which are beneficially owned by the stockholder on the date of such stockholder’s notice, and (b) not more than ten days after receipt by the nominating stockholder of a written request from the Secretary, such additional information as the Secretary may reasonably require. At the request of the Secretary of the Corporation, each nominee proposed by the Board of Directors shall provide the Corporation with such information concerning himself or herself as is required to be set forth in a stockholder’s notice of nomination. Notwithstanding anything in these By-laws to the contrary, no person shall be eligible for election as a director except in accordance with the provisions of this Section 3. The officer of the Corporation or other person presiding over the annual meeting shall, if the facts so warrant, determine that a nomination was not made in accordance with the provisions of this Section 3 and, if he or she should so determine, such officer shall so declare to the meeting and any such defective nomination shall be disregarded.

SECTION 5. Quorum. The holders of a majority of the voting power of the outstanding shares of the capital stock of the Corporation entitled to vote thereat, present in person or represented by proxy, shall constitute a quorum for the transaction of business at all meetings of the stockholders except as may otherwise be provided by law, by the Certificate of Incorporation or by these By-laws; but, if there be less than a quorum, the holders of a majority of the voting power so present or represented may adjourn the meeting from time to time.

SECTION 6. Voting and Proxies. Each stockholder shall, subject to the provisions of the Certificate of Incorporation, at each meeting of the stockholders be entitled to one vote in person or by proxy for each share of the stock of the Corporation which has voting power on the matter in question and which shall have been held by such stockholder and registered in his or her name on the books of the Corporation:

(b) if no such record date shall have been so fixed, then at the close of business on the day next preceding the day on which notice of the meeting shall be given.

At all meetings of the stockholders, all matters, except for the election of directors, which shall be decided pursuant to the provisions of Article III, Section 3, and as otherwise provided in the Certificate of Incorporation, in these By-laws, or by law, shall be decided by the vote of the holders of a majority of the voting power of the outstanding shares of the capital stock of the Corporation entitled to vote thereat present in person or by proxy, a quorum being present. Proxies may be submitted in any manner permitted by the laws of the State of Delaware. The vote at any meeting of the stockholders on any question need not be by ballot, unless so directed by the chairman of the meeting.
