1.5  Advance Notice of Other Matters to be Presented by Stockholders.   At any annual meeting or special meeting of stockholders, only such business as is properly brought before the meeting in accordance with this paragraph may be transacted. To be properly brought before any meeting, any proposed business must be either (a) specified in the notice of the meeting (or any supplement thereto) given by or at the direction of the Board, (b) otherwise properly brought before the meeting by or at the direction of the Board, or (c) if brought before the meeting by a stockholder, then (1) written notification of such proposed business (a “Stockholder Notification” ) must have been received by the Secretary of the Corporation from a stockholder of record on the record date for the determination of stockholders entitled to vote at such meeting not later than (i), with respect to business to be proposed at an annual meeting of stockholders, 120 days prior to the anniversary date of the immediately preceding annual meeting ( provided , that if the date of the annual meeting is more than 30 days before or after the anniversary date of the immediately preceding annual meeting, the Stockholder Notification must have been received within 15

days after the public announcement by the Corporation of the date of the annual meeting) and (ii) with respect to business to be proposed at a special meeting of stockholders, the close of business on the 15th day following the date on which notice of such meeting is first given to stockholders or public disclosure of the meeting is made, whichever is earlier. Such Stockholder Notification shall set forth (A) a brief description of the business desired to be brought before the 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 (B) as to the stockholder giving notification, (i) the name and address of such stockholder and (ii) the class or series and total number of all shares of the Corporation that are owned beneficially and of record by such stockholder and, if such shares are not beneficially owned solely and directly by such stockholder, the beneficial owner(s) of such shares.

The notifying stockholder may cure such deficiencies within 14 days after receipt of such advice, failing which the Stockholder Notification shall be deemed invalid.

1.6  Quorum for Stockholder Meetings.   At any meeting of the stockholders, the presence, in person or by proxy, of stockholders entitled to cast at least a majority of the votes which all stockholders are entitled to vote upon a matter shall constitute a quorum for the transaction of business upon such matter, and the stockholders present at a duly organized meeting can continue to do business until adjournment, notwithstanding the withdrawal of enough stockholders to leave less than a quorum. If a meeting cannot be organized because a quorum has not attended, those present may, except as otherwise provided by law, adjourn the meeting to such time and place as they may determine, but in the case of any meeting called for the election of directors, those who attend the second of such adjourned meetings, although less than a quorum, shall nevertheless constitute a quorum for the purpose of electing directors.

1.7  Voting.   Except as otherwise provided in the Corporation’s Certificate of Incorporation, each stockholder of record shall have, at every stockholders’ meeting, one vote for every share standing in his or her name on the books of the Corporation. “Certificate of Incorporation” means the Certificate of Incorporation of the Corporation, as filed with the Secretary of State of the State of Delaware, as it may from time to time be amended and in effect in accordance with law, and shall include any certificate of designations determining the designation, voting rights, preferences, limitations and special rights of any shares of the Corporation which have been adopted by the Board as permitted by the certificate of incorporation and the law, as then in effect.

1.8  Proxies.   Every stockholder entitled to vote at a meeting of stockholders may authorize another person or persons to act for such stockholder by proxy. A proxy may be submitted to the Secretary by a stockholder in writing, by telephone, electronically or any other means permitted by law.

1.9  Required Votes for Stockholder Action.   Except in respect of the election of directors (as to which the requisite vote is outlined in the following paragraph ), all questions submitted to the stockholders and all actions by the stockholders shall be decided by the affirmative vote of the stockholders present, in person or by proxy, entitled to cast at least a majority of the votes which all stockholders present are entitled to vote on the matter, at any meeting at which a quorum is present, unless otherwise provided by the Certificate of Incorporation, the Bylaws or by law. For purposes of this section, in the event that a holder of shares of a class or series which are entitled to vote on a matter is present in person or by proxy at a meeting but is not permitted by reason of a legal disability or by a contractual restriction or otherwise to vote the shares such holder holds on such matter, the shares held by such holder and not so permitted to be voted shall nevertheless be considered entitled to vote and present for purposes of determining the number of votes required for stockholder action.

Notwithstanding the foregoing provisions of this Section 1.9, a nominee for director of the Corporation shall only be elected if, at any meeting of the stockholders held for the election of directors at which a quorum is present, the votes cast for the nominee’s election exceed the votes cast against the nominee’s election; provided, however, that a plurality of all votes cast at a meeting of stockholders at which a quorum is present is sufficient to elect a nominee to the Board if, in connection with the meeting, (i) a stockholder has duly nominated an individual for election to the Board in accordance with the advance notice and other nomination procedures and requirements adopted by the Corporation from time to time and set forth in these Bylaws and (ii) the stockholder nomination has not been

withdrawn on or prior to the date that is fourteen (14) days prior to the date on which the Corporation first mails its notice of meeting to the stockholders. Votes cast “for” and “against” a nominee shall exclude votes “withheld”, “abstentions” and “broker non-votes” with respect to that nominee’s election. If directors are to be elected by a plurality of the votes cast, stockholders shall not be permitted to vote against a nominee.

1.10  Ballots; Judges of Election.   Elections for directors need not be by ballot but the Board or the presiding officer at a meeting of stockholders may direct the use of ballots for voting at the meeting. In advance of any meeting of stockholders, the Board may appoint judges of election who need not be stockholders to act at such meeting or any adjournment thereof, and if such appointment is not made, the presiding officer of any such meeting may, and on request of any stockholder or his proxy shall, make such appointment at the meeting. The number of judges shall be one or three and, if appointed at a meeting on request of one or more stockholders or their proxies, the majority of the shares present and entitled to vote shall determine whether one or three judges are to be appointed. No person who is a candidate for office shall act as a judge. In case any person appointed as judge fails to appear or fails or refuses to act, the vacancy may be filled by appointment made by the Board in advance of the convening of the meeting or at the meeting by the person or officer presiding at the meeting. On request of the presiding officer of the meeting or of any stockholder or his proxy, the judges shall make a report in writing of any challenge or question or matter determined by them and execute a certificate of any fact found by them.

1.11  Action by Consent Without a Meeting.   To the fullest extent and in the manner permitted by law, any action required or permitted to be taken at a meeting of the stockholders or of a class or series of stockholders may be taken without a meeting of the stockholders or of such class or series of stockholders upon the consent in writing signed by such stockholders who would have been entitled to vote the minimum number of votes that would be necessary to authorize the action at a meeting at which all the stockholders entitled to vote thereon were present and voting. The consents shall be filed with the Secretary.

1.12  List of Stockholders Entitled to Vote.   The officer who has charge of the stock ledger shall prepare and make, at least 10 days before every meeting of stockholders, a complete list of the stockholders entitled to vote at the meeting, arranged in alphabetical order, and showing the address of each stockholder and the number of shares registered in the name of each stockholder. Such list shall be open to the examination of any stockholder, for any purpose germane to the meeting at least 10 days prior to the meeting during ordinary business hours at the principal place of business of the Corporation. A list of stockholders entitled to vote at the meeting shall be produced and kept at the time and place of the meeting during the whole time thereof and may be examined by any stockholder who is present. Except as otherwise provided by law, the stock ledger shall be the only evidence as to who are the stockholders entitled to examine the list of stockholders required by this Section 1.12 or to vote in person or by proxy at any meeting of stockholders.

1.13  Inclusion of Stockholder Director Nominations in the Corporation’s Proxy Materials.

(a)                                  The Corporation shall include in its proxy statement for any annual meeting of stockholders the name, together with the Required Information (as defined below), of any Stockholder Nominee identified in a timely notice that satisfies this Section 1.13 delivered by one or more stockholders who at the time the request is delivered satisfy, or are acting on behalf of persons who satisfy, the ownership and other requirements of both Sections 1.4 and this Section 1.13 (such stockholder or stockholders, and any person on whose behalf they are acting, the “ Eligible Stockholder ”), and who expressly elects at the time of providing the notice required by this Section 1.13 to have its nominee included in the Corporation’s proxy materials pursuant to this Section 1.13.

(b)                                  For purposes of this Section 1.13, the “ Required Information ” that the Corporation will include in its proxy statement is (i) the information concerning the Stockholder Nominee and the Eligible Stockholder that, as determined by the Corporation, is required to be disclosed in a proxy statement filed pursuant to the proxy rules of the SEC, and (ii) if the Eligible Stockholder so elects, a Statement (as defined below).

(d)                                  The number of Stockholder Nominees (including Stockholder Nominees that were submitted by an Eligible Stockholder for inclusion in the Corporation’s proxy statement pursuant to this Section 1.13 but either are subsequently withdrawn or that the Board decides to nominate (a “ Board Nominee ”)) appearing in the Corporation’s proxy statement with respect to a meeting of stockholders shall not exceed the greater of (i) two or (ii) 20% of the number of directors in office as of the last day on which notice of a nomination may be delivered pursuant to Section 1.4 (the “ Final Proxy Access Nomination Date ”) or, if such 20% amount is not a whole number, the closest whole number below 20% (the greater of (i) and (ii), the “ Permitted Number ”); provided, however, that in the event that one or more vacancies for any reason occurs on the Board of Directors at any time after the Final Proxy Access Nomination Date and before the date of the applicable annual meeting of stockholders and the Board resolves to reduce the size of the Board of Directors in connection therewith, the Permitted Number shall be calculated based on the number of directors in office as so reduced. In the event that the number of Stockholder Nominees submitted by Eligible Stockholders pursuant to this Section 1.13 exceeds the Permitted Number, each Eligible Stockholder shall select one Stockholder Nominee for inclusion in the Corporation’s proxy statement until the Permitted Number is reached, going in order of the amount (greatest to least) of the Corporation’s common stock entitled to vote on the election of directors as disclosed as owned in the written notice of nomination submitted to the Corporation.

(f)                                    For purposes of this Section 1.13, an Eligible Stockholder shall be deemed to “own” only those outstanding shares of the Corporation’s common stock as to which the stockholder possesses both (i) the full voting and investment rights pertaining to the shares and (ii) the full economic interest in (including the opportunity for profit and risk of loss on) such shares; provided that the number of shares calculated in accordance with clauses (i) and (ii) shall not include any shares (x) sold by such stockholder or any of its affiliates in any transaction that has not been settled or closed, (y) borrowed by such stockholder or any of its affiliates for any purposes or purchased by such stockholder or any of its affiliates pursuant to an agreement to resell or (z) subject to any option, warrant, forward contract, swap, contract of sale, other derivative or similar agreement entered into by such stockholder or any of its affiliates, whether any such instrument or agreement is to be settled with shares or with cash based on the notional amount or value of outstanding shares of the Corporation’s common stock, in any such case which instrument or agreement has, or is intended to have, the purpose or effect of (1) reducing in any manner, to any extent or at any time in the future, such stockholder’s or affiliates’ full right to vote or direct the voting of any such shares, and/or (2) hedging, offsetting or altering to any degree gain or loss arising from the full economic ownership of such shares by such stockholder or affiliate. A stockholder shall “own” shares held in the name of a nominee or other intermediary so long as the stockholder retains the right to instruct how the shares are voted with respect to the election of directors and possesses the full economic interest in the shares. A stockholder’s ownership of shares shall be deemed to continue during any period in which (i) the stockholder has loaned such shares, provided that the stockholder has the power to recall such loaned shares on three business days’ notice; or (ii) the stockholder has delegated any voting power by means of a proxy, power of attorney or other instrument or arrangement, provided that such delegation is revocable at any time by the stockholder.

Notwithstanding anything to the contrary contained in this Section 1.13, the Corporation may omit from its proxy materials any information or Statement that it believes would violate any applicable law, rule, regulation or listing standard.

(h)                                  The Corporation shall not be required to include, pursuant to this Section 1.13, a Stockholder Nominee in its proxy materials (i) if the Eligible Stockholder who has nominated such Stockholder Nominee has engaged in or is currently engaged in, or has been or is a “participant” in another person’s, “solicitation” within the meaning of Rule 14a-1(l) under the Exchange Act in support of the election of any individual as a director at the meeting other than its Stockholder Nominee(s) or a Board Nominee, (ii) who is not independent under the Applicable Independence Standards, as determined by the Board of Directors, (iii) whose election as a member of the Board of Directors would cause the Corporation to be in violation of these By-Laws, the Corporation’s certificate of incorporation, the listing standards of the principal exchange upon which the Corporation’s capital stock is traded, or any applicable state or federal law, rule or regulation, (iv) who is or has been, within the past three years, an officer or director of a competitor, as defined in Section 8 of the Clayton Antitrust Act of 1914, (v) who is a named subject of a pending

(i)                                      Notwithstanding anything to the contrary set forth herein, the Board of Directors or the presiding officer at the annual meeting shall declare a nomination by an Eligible Stockholder to be invalid, and such nomination shall be disregarded notwithstanding that proxies in respect of such vote may have been received by the Corporation, if (i) the Stockholder Nominee and/or the applicable Eligible Stockholder shall have breached its or their obligations, agreements or representations under this Article I, as determined by the Board of Directors or the presiding officer at the annual meeting, or (ii) the Eligible Stockholder (or any member of a group that together is an Eligible Stockholder pursuant to the terms hereof) or a qualified representative thereof does not appear at the meeting to present any nomination pursuant to this Section 1.13.

(j)                                     The Eligible Stockholder (including any person who owns shares that constitute part of the Eligible Stockholder’s ownership for purposes of satisfying Section 1.13(e)) shall file with the SEC any solicitation or other communication with the Corporation’s stockholders relating to the meeting at which the Stockholder Nominee will be nominated, regardless of whether any such filing is required under Regulation 14A of the Exchange Act or whether any exemption from filing is available for such solicitation or other communication under Regulation 14A of the Exchange Act.

(k)                                  No person may be a member of more than one group of persons constituting an Eligible Stockholder under this Section 1.13.

(l)                                      Any Stockholder Nominee who is included in the Corporation’s proxy materials for a particular meeting of stockholders but either (i) withdraws from or becomes ineligible or unavailable for election at the meeting, or (ii) does not receive at least 25% of the votes cast in favor of the Stockholder Nominee’s election, shall be ineligible to be a Stockholder Nominee for purposes of this Section 1.13 for the next two annual meetings of stockholders following the meeting for which the Stockholder Nominee has been nominated for election.

2.9  Resignation and Removal of Directors.

(a)                                  Any director may resign at any time by delivering his resignation in writing to the President or Secretary of the Corporation, to take effect at the time specified in the resignation.

A Chairman or Vice Chairman of the Board shall not be considered an officer of the Corporation unless otherwise provided by the Board. The position of Chairman of the Board shall not be held by the then current Chief Executive Officer of the Corporation.

2.11  Vacancies.   In the event of any vacancy on the Board, however occurring (including any vacancy created by an increase in the size of the Board), such vacancy shall be filled promptly by the affirmative vote of a majority of directors then in office or a remaining sole director or in accordance with Section 1.9 of these Bylaws, the stockholders of the Corporation.

2.13  Indemnification and Advancement of Defense Costs for Directors and Officers.

(a)                                  Right to Indemnification.

Each person who was or is a party or is threatened to be made a party to or is involved in any threatened, pending or completed action, suit or proceeding, whether civil, criminal, administrative or investigative (“ Proceeding ”), by reason of the fact that he or she, or a person of whom he or she is the legal representative, is or was a director or officer of the Corporation or, as a director or officer of the Corporation, is or was serving at the written request of the Corporation’s Board of Directors or its designee as a director, officer, employee or agent of another corporation, partnership, joint venture, trust or other enterprise, including service with respect to employee benefit plans, whether the basis of such Proceeding is alleged action in an official capacity as a director, officer, trustee, employee or agent or in any other capacity, shall be indemnified and held harmless by the Corporation to the fullest extent authorized by law, including but not limited to the Delaware General Corporation Law, as the same exists or may hereafter be amended (but, in the case of any such amendment, only to the extent that such amendment permits the Corporation to provide broader indemnification rights than said Law permitted the Corporation to provide prior to such amendment), against all expenses, liability and loss (including attorney’s fees, judgments, fines, ERISA excise taxes or penalties and amounts paid or to be paid in settlement) reasonably incurred or suffered by such person in connection therewith; provided, however, that the Corporation shall indemnify any such person seeking indemnity in connection with an action, suit or proceeding (or part thereof) initiated by such person only if such action, suit or proceeding (or part thereof) initiated by such person was authorized by the board of directors of the Corporation. Such right shall include the right to be paid by the Corporation expenses, including attorney’s fees, incurred in defending any such Proceeding in advance of its final disposition; provided, however, that the payment of such expenses in advance of the final disposition of such Proceeding shall be made only upon delivery to the Corporation of an undertaking, by or on behalf of such director or officer, in which such director or officer agrees to repay all amounts so advanced if it should be ultimately determined by a court or other tribunal that such person is not entitled to be indemnified under this Section or otherwise.

(b)                                  Right of Claimant to Bring Suit.

(i)                            If a claim under paragraph (a) is not paid in full by the Corporation within thirty days after a written claim therefor has been received by the Corporation, the claimant may any time thereafter bring suit against the Corporation to recover the unpaid amount of the claim and, if successful in whole or in part, the claimant shall be entitled to be paid also the expense of prosecuting such claim. In any such action, the burden of proof shall be on the Corporation to prove the claimant is not entitled to such payment.

(ii)                         Neither the failure of the Corporation (including its Board of Directors, independent legal counsel, or its shareholders) to have made a determination prior to the commencement of such action that the claimant is entitled to indemnification or advancement under the circumstances, nor an actual determination by the Corporation (including its Board of Directors, independent legal counsel, or its shareholders) that the claimant is not entitled to indemnification or advancement, shall be a defense to the action or create a presumption that the claimant is not entitled to indemnification or advancement.

(c)                                   Contractual Rights; Applicability.

The right to be indemnified or to the reimbursement or advancement of expenses pursuant hereto (i) is a contract right based upon good and valuable consideration, pursuant to which the person entitled thereto may bring suit as if the provisions hereof were set forth in a separate written contract between the Corporation and the director or officer, (ii) is intended to be retroactive and shall be available with respect to events occurring prior to the adoption hereof, and (iii) shall continue to exist after the rescission or restrictive modification hereof with respect to events occurring prior thereto.

(d)                                  Requested Service.

Any director or officer of the Corporation serving, in any capacity, and any other person serving as director or officer of, (i) another organization of which a majority of the outstanding voting securities representing the present right to vote for the election of its directors or equivalent executives is owned directly or indirectly by the Corporation, or (ii) any employee benefit plan of the Corporation or of any organization referred to in clause (i), shall be deemed to be doing so at the written request of the Corporation’s Board of Directors.

(e)                                   Non-Exclusivity of Rights.

The rights conferred on any person by paragraphs (a) through (d) above shall not be exclusive of and shall be in addition to any other right which such person may have or may hereafter acquire under any statute, provision of the Certificate of Incorporation, Code of Regulations, bylaws, agreement, vote of shareholders or disinterested directors or otherwise.

(f)                                    Insurance.

The Corporation may maintain insurance, at its expense, to protect itself and any such director, officer, employee or agent of the Corporation or another corporation, partnership, joint venture, trust or other enterprise against such expense, liability or loss, whether or not the Corporation would have the power to indemnify such person against such expense, liability or loss under the Delaware General Corporation Law.

2.14   Failed Director Election.   Any director who fails to receive the requisite number of votes for reelection shall be required to promptly tender his or her resignation to the Board. The corporate governance and nominating committee of the Board shall make a recommendation to the Board on whether to accept or reject the offer of resignation, or whether other action should be taken. In reaching its decision, the Board will consider the corporate governance and nominating committee’s recommendation and may consider any other factors it deems relevant, which may include the director’s qualifications, the director’s past and expected future contributions to the Corporation, the overall composition of the Board and committees of the Board, whether accepting the tendered resignation would cause the Corporation to fail to meet any applicable rule or regulation (including the New York Stock Exchange listing standards and the requirements of the federal securities laws) and the percentage of outstanding shares represented by the votes cast at the meeting. The director who tenders his or her offer of resignation shall not participate in the corporate governance and nominating committee’s recommendation or the Board’s decision. The Board will act on the resignation within 90 days following certification of the stockholder vote for the meeting and will promptly disclose its decision and rationale as to whether to accept the resignation (or the reasons for rejecting the resignation, if applicable) in a press release, in a filing with the Securities and Exchange Commission or by other public announcement, which may include a posting on the Corporation’s website.

3.                                       COMMITTEES.

3.1  Committees of the Board.   The Board may, by resolution adopted by a majority of the entire Board, at any time designate one or more committees, each committee to consist of one or more of the directors of the Corporation, except as otherwise provided by the Bylaws. In the absence or disqualification of any member of a committee, the member or members present at a meeting of the committee and not disqualified, whether or not a quorum, may unanimously appoint another director to act at the meeting in place of the absent or disqualified member. Any such committee, to the extent provided in such resolution, shall have and may exercise any or all of the authority and responsibility of the Board in the management of the business and affairs of the Corporation, except as otherwise provided by law, the Certificate of Incorporation or the Bylaws. Except as otherwise provided by the Certificate of Incorporation, the Bylaws or action of the Board, with respect to all standing committees of the Board, including the Audit Committee, a majority of each such committee shall be necessary to constitute a quorum. Each committee shall keep a record of its actions and all material actions taken by a committee on behalf of the Board shall be reported to the full Board periodically. In all other respects, the Board may, by resolution adopted by a majority of the entire Board, establish rules of procedure for a committee, including designating a member of a committee as its chair, and a committee shall meet as provided by those rules or by resolutions of the Board. In the absence of such rules each committee shall conduct its business in the same manner as the Board conducts its business pursuant to Article II. In the absence of the designation by the Board of the chairman of a committee or the adoption by the Board of rules of procedure for a committee, the committee may adopt its own rules of procedure and elect its chair. In the event any or all of the members of any committee are required to be independent under any then applicable listing standards to which the Company is subject or any other legal requirement, for the performance of some, but not all, of the duties of such committee, the Board may establish a separate committee for the performance of only those duties the performance of which requires such independent directors.

The Board shall approve a charter describing the purposes, functions and responsibilities of each standing committee of the Board. Each standing committee of the Board shall prepare and recommend to the Board for its approval the committee’s charter. Each standing committee of the Board shall have the authority and responsibility provided by its Board-approved charter, subject to further action by the Board, and no further authorization of the Board shall be

necessary for actions by a committee within the scope of its charter. Any other committee of the Board may likewise prepare and recommend to the Board a charter for the committee and shall have the authority and responsibility provided by its Board-approved charter.
