ARTICLE I
STOCKHOLDERS

     Section 1.1 Annual Meeting. An annual meeting of the stockholders, for the election of directors to succeed those whose terms expire and for the transaction of such other business as may properly come before the meeting, shall be held at such place, on such date, and at such time as the Board of Directors shall each year fix, which date shall be within thirteen months after the organization of the corporation or after its last annual meeting of stockholders.

     Section 1.2 Special Meetings. Special meetings of the stockholders, for any purpose or purposes prescribed in the notice of the meeting, may be called by (1) the Board of Directors pursuant to a resolution adopted by a majority of the total number of authorized directors (whether or not there exist any vacancies in previously authorized directorships at the time any such resolution is presented to the Board for adoption), or (2) the Chairman of the Board, and shall be held at such place, on such date, and at such time as they shall fix. Business transacted at special meetings shall be confined to the purpose or purposes stated in the notice.

     Section 1.3 Notice of Meetings. Written notice of the place, date, and time of all meetings of the stockholders shall be given, not less than ten (10) nor more than sixty (60) days before the date on which the meeting is to be held, to each stockholder entitled to vote at such meeting, as provided herein or otherwise required by law (meaning, here and hereinafter, as required from time to time by the Delaware General Corporation Law, the Certificate of Incorporation of the Corporation or the rules and regulations promulgated by the Securities and Exchange Commission).

     When a meeting is adjourned to another place, date or time, written notice need not be given of the adjourned meeting if the place, date and time thereof are announced at the meeting at which the adjournment is taken; provided, however, that if the date of any adjourned meeting is more than thirty (30) days after the date for which the meeting was originally noticed, or if a new record date is fixed for the adjourned meeting, written notice of the place, date, and time of the adjourned meeting shall be given in conformity herewith. At any adjourned meeting, any business may be transacted which might have been transacted at the original meeting.

     Section 1.4 Quorum. At any meeting of the stockholders, the holders of a majority of all of the shares of the stock entitled to vote at the meeting, present in person or by proxy, shall constitute a quorum for all purposes, unless or except to the extent that the presence of a larger number may be required by law or by the Certificate of Incorporation or Bylaws of this corporation.

     If a quorum shall fail to attend any meeting, the chairman of the meeting or the holders of a majority of the shares of stock entitled to vote who are present, in person or by proxy, may adjourn the meeting to another place, date, or time.

     If a notice of any adjourned special meeting of stockholders is sent to all stockholders entitled to vote thereat, stating that it will be held with those present constituting a quorum, then except as otherwise required by law, those present at such adjourned meeting shall constitute a quorum, and all matters shall be determined by a majority of the votes cast at such meeting.

     Section 1.5 Organization. Such person as the Board of Directors may have designated or, in the absence of such a person, the Chairman, if there is such an officer, or if not, the Presiding Director of the Corporation, or in the absence of all of the above, such person as may be chosen by the holders of a majority of the shares 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.

     Section 1.6 Conduct of Business. 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 seem to him in order.

     Section 1.7 Notice of Stockholder Business. At an annual or special meeting of the stockholders, only such business shall be conducted as shall have been properly brought before the meeting. To be properly brought before a meeting, business must be (a) specified in the notice of meeting (or any supplement thereto) given by or at the direction of the Board of Directors, (b) properly brought before the meeting by or at the direction of the Board of Directors, or (c) if, and only if, the notice of an annual meeting or special meeting specifically provides for and describes the business to be brought before the meeting by stockholders, properly brought before the annual meeting or special meeting by a stockholder. For business to be properly brought before a meeting by a stockholder, the stockholder must have given timely notice thereof in writing to the Secretary of the Corporation. To be timely, a stockholder’s notice must be delivered to or mailed and received at the principal offices of the Corporation no later than the date on which stockholder proposals to be included in the stockholder proxy must be received by the Corporation under the requirements of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), and the rules promulgated thereunder. A stockholder’s notice to the Secretary shall set forth as to each matter the stockholder proposes to bring before the annual or special meeting (i) a brief description of the business desired to be brought before the annual or special meeting and the reasons for conducting such business at the annual or special 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 of the Corporation which are beneficially owned by the stockholder, (iv) any material interest of the stockholder in such business, and (v) any direct or indirect pecuniary or economic interest in any capital stock or other security of the Corporation of such person, including, without limitation, any derivative instrument, swap, option, warrant, short interest, hedge, or profit-sharing arrangement. Notwithstanding anything in the Bylaws to the contrary (i) no business shall be conducted at an annual or special meeting except in accordance with the procedures set forth in this Section 1.7, (ii) other than with respect to stockholder nominations for the election of Directors, the procedures in clause (c) of this Section 1.7 shall be the exclusive means for a stockholder to properly submit business (other than business properly brought under Rule 14a-8 under the Exchange Act and included in the Corporation’s proxy statement) before an annual or special meeting of stockholders; it being understood that a

stockholder seeking to nominate directors at an annual or special meeting of stockholders must comply with notice and information requirements of Section 2.11, and (iii) the procedures in Section 2.11 (including the notice and information requirements therein) shall be the exclusive means for a stockholder to submit nominations for the election of Directors before an annual or special meeting of stockholders. The chairman of an annual or special meeting shall, if the facts warrant, determine and declare to the meeting that business was not properly brought before the meeting and in accordance with the provisions of this Section 1.7, and if he should so determine, he shall so declare to the meeting and any such business not properly brought before the meeting shall not be transacted.

     Section 1.8 Proxies and Voting. At any meeting of the stockholders, every stockholder entitled to vote may vote in person or by proxy authorized by an instrument in writing filed in accordance with the procedure established for the meeting.

     Each stockholder shall have one vote for every share of stock entitled to vote which is registered in his name on the record date for the meeting, except as otherwise provided herein or required by law.

     All voting, except where otherwise required by law, may be by a voice vote; provided, however, that upon demand therefor by a stockholder entitled to vote or by his proxy, a stock vote shall be taken. Every stock vote shall be taken by ballots, each of which shall state the name of the stockholder or proxy voting and such other information as may be required under the procedure established for the meeting. Every vote taken by ballots shall be counted by an inspector or inspectors appointed by the chairman of the meeting.

     Except as otherwise required by applicable law or by the Certificate of this Corporation or these Bylaws, at any meeting of stockholders for the election of one or more Directors at which a quorum is present, each Director shall be elected by the vote of a majority of the votes cast with respect to the Director, provided that if, as of a date that is ten (10) days in advance of the date on which the Corporation files its definitive proxy statement with the SEC (regardless of whether thereafter revised or supplemented), 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 votes cast by the Stockholders entitled to vote at the election. For purposes of this Section 1.8, a majority of the votes cast means that the number of shares voted “for” a Director exceeds the number of votes cast “against” that Director. The following shall not be votes cast: (a) a share otherwise present at the meeting but for which there is an abstention; and (b) a share otherwise present at the meeting as to which a shareholder gives no authority or direction. If a Director then serving on the Board of Directors does not receive the required majority, the Director shall tender his or her resignation to the Board. Within ninety (90) days after the date of the certification of the election results, the Governance and Nominating Committee or other committee that may be designated by the Board will make a recommendation to the Board on whether to accept or reject the resignation, or whether other action should be taken, and the Board will act on such committee’s recommendation and publicly disclose its decision and the rationale behind it. In addition, and except as otherwise required by law or by the Certificate of this Corporation or these Bylaws, all other matters shall be determined by a majority of the votes cast.

     Section 1.9 Stock List. A complete list of stockholders entitled to vote at any meeting of stockholders, arranged in alphabetical order for each class of stock and showing the address of each such stockholder and the number of shares registered in his name, shall be open to the examination of any such stockholder, for any purpose germane to the meeting, during ordinary business hours for a period of at least ten (10) days prior to the meeting, either at a place within the city where the meeting is to be held, which place shall be specified in the notice of the meeting, or if not so specified, at the place where the meeting is to be held.

     The stock list shall also be kept at the place of the meeting during the whole time thereof and shall be open to the examination of any such stockholder who is present. This list shall presumptively determine the identity of the stockholders entitled to vote at the meeting and the number of shares held by each of them.

     Section 1.10 No Stockholder Action by Written Consent. The stockholders of the Corporation may not act by written consent and may act only at an annual or special meeting of the stockholders.

ARTICLE II
BOARD OF DIRECTORS

     Section 2.1 Number and Term of Office. The number of directors shall be fixed from time to time exclusively by the Board of Directors pursuant to a resolution adopted by a majority of the total number of authorized directors (whether or not there exist any vacancies in previously authorized directorships at the time any such resolution is presented to the Board for adoption). The directors shall be elected at the annual meeting of the stockholders, who shall vote for such directors as provided in the Certificate of Incorporation. The directors shall be divided into three (3) classes, with the term of office of the first class to expire at the first annual meeting of stockholders held after the closing of the first sale of the Corporation’s common stock pursuant to a firmly underwritten registered public offering (the “IPO”); the term of office of the second class to expire at the second annual meeting of stockholders held after the IPO; the term of office of the third class to expire at the third annual meeting of stockholders held after the IPO; and thereafter for each such term to expire at each third succeeding annual meeting of stockholders after such election. All directors shall hold office until the expiration of the term for which elected and until their respective successors are elected, except in the case of the death, resignation or removal of any director. Directors need not be stockholders.

     Section 2.2 Vacancies and Newly Created Directorships. Subject to the rights of the holders of any series of Preferred Stock then outstanding, newly created directorships resulting from any increase in the authorized number of directors or any vacancies in the Board of Directors resulting from death, resignation, retirement, disqualification, or other cause (other then removal from office by a vote of the stockholders) may be filled only by a majority vote of the directors then in office, though less than a quorum, and directors so chosen shall hold office for a term expiring at the next annual meeting of stockholders at which the term of office to which they have been elected expires, and until their respective successors are elected, except in the case of death or resignation in which case the directors so chosen shall hold office for a term

expiring at the next annual meeting of stockholders. No decrease in the number of directors constituting the Board of Directors shall shorten the term of any incumbent director.

     Section 2.3 Removal. Subject to the limitations stated in the Certificate of Incorporation, any director, or the entire Board of Directors, may be removed from office at any time, with or without cause, but only by the affirmative vote of the holders of at least a majority of the voting power of its then outstanding shares of stock of the Corporation entitled to vote generally in the election of directors, voting together as a single class. Any director or the entire Board of Directors may be removed from office before the expiration of the applicable term of office only with cause. Vacancies in the Board of Directors resulting from such removal may be filled by (i) a majority of the directors then in office, though less than a quorum, or (ii) the stockholders at a special meeting of the stockholders properly called for that purpose, by the vote of the holders of a majority of the shares entitled to vote at such special meeting. Directors so chosen shall hold office until the next annual meeting of stockholders.

     Section 2.4 Regular Meetings. Regular meetings of the Board of Directors shall be held at such place or places, on such date or dates, and at such time or times as shall have been established by the Board of Directors and publicized among all directors. A notice of each regular meeting shall not be required.

     Section 2.5 Special Meetings. Special meetings of the Board of Directors may be called by one third of the directors then in office (rounded up to the nearest whole number), by the chairman of the board or by the Chief Executive Officer (“CEO”), or by the Presiding Director and shall be held at such place, on such date, and at such time as they or he shall fix. Notice of the place, date, and time of each such special meeting shall be given each director by whom it is not waived:

     (i) by mailing written notice not less than five (5) days before the meeting;

     (ii) delivering written notice by overnight courier not less than one (1) day before the meeting

     (iii) delivering written notice by overseas courier service not less than two (2) days before the meeting; or

     (iv) providing notice thereof by telephone, telecopy, email or personal delivery not less than twelve (12) hours before the meeting.

Unless otherwise indicated in the notice thereof, any and all business may be transacted at a special meeting.

     Section 2.6 Quorum. At any meeting of the Board of Directors, a majority of the total number of authorized directors shall constitute a quorum for all purposes. If a quorum shall fail to attend any meeting, a majority of those present may adjourn the meeting to another place, date, or time, without further notice or waiver thereof.

     Section 2.7 Participation in Meetings by Conference Telephone. Members of the Board of Directors, or of any committee of the Board of Directors, may participate in a meeting

of such Board or committee by means of conference telephone or similar communications equipment by means of which all persons participating in the meeting can hear each other and such participation shall constitute presence in person at such meeting.

     Section 2.8 Conduct of Business. At any meeting of the Board of Directors, business shall be transacted in such order and manner as the Board may from time to time determine, and all matters shall be determined by the vote of a majority of the directors present, except as otherwise provided herein or required by law. Action may be taken by the Board of Directors without a meeting if all members thereof consent thereto in writing, and the writing or writings are filed with the minutes of proceedings of the Board of Directors.

     Section 2.9 Powers. The Board of Directors may, except as otherwise required by law, exercise all such powers and do all such acts and things as may be exercised or done by the Corporation, including, without limiting the generality of the foregoing, the unqualified power:

          (1) To declare dividends from time to time in accordance with law;

          (2) To purchase or otherwise acquire any property, rights or privileges on such terms as it shall determine;

          (3) To authorize the creation, making and issuance, in such form as it may determine, of written obligations of every kind, negotiable or non negotiable, secured or unsecured, and

          (4) To remove any officer of the Corporation with or without cause, and from time to time to pass on the powers and duties of any officer upon any other person for the time being;

          (5) To confer upon any officer of the Corporation the power to appoint, remove and suspend subordinate officers, employees and agents;

          (6) To adopt from time to time such stock option, stock purchase, bonus or other compensation plans for directors, officers, employees and agents of the Corporation and its subsidiaries as it may determine;

          (7) To adopt from time to time such insurance, retirement, and other benefit plans for directors, officers, employees and agents of the Corporation and its subsidiaries as it may determine;

          (8) To adopt from time to time regulations, not inconsistent with these Bylaws, for the management of the Corporation’s business and affairs; and

          (9) To appoint one of the independent directors to serve as Presiding Director and to designate the authority and responsibilities of the Presiding Director.

     Section 2.10 Compensation of Directors. Directors, as such, may receive, pursuant to resolution of the Board of Directors, fixed fees and other compensation for their services as

directors, including, without limitation, their services as members of committees of the Board of Directors.

     Section 2.11 Nomination of Director Candidates. Subject to the rights of holders of any class or series of Preferred Stock then outstanding, nominations for the election of Directors may be made by the Board of Directors or a proxy committee appointed by the Board of Directors or by any stockholder entitled to vote in the election of Directors generally who complies with the procedures set forth in this Section 2.11 and who is a stockholder of record at the time notice is delivered to the Secretary of the Corporation. However, any stockholder entitled to vote in the election of Directors generally may nominate one or more persons for election as Directors at a meeting only if timely notice of such stockholder’s intent to make such nomination or nominations has been given in writing to the Secretary of the Corporation in accordance with this Section 2.11. To be timely, a stockholder nomination for a director to be elected at an annual meeting shall be received at the Corporation’s principal executive offices not less than 120 calendar days in advance of the first year anniversary of the date that the Corporation’s proxy statement was released to stockholders in connection with the previous year’s annual meeting of stockholders, except that if no annual meeting was held in the previous year or the date of the annual meeting has been changed by more than 30 calendar days from the date contemplated at the time of the previous year’s proxy statement, or in the event of a nomination for director to be elected at a special meeting, notice by the stockholders to be timely must be received not later than the close of business on the tenth day following the day on which such notice of the date of the special meeting was mailed or such public disclosure was made. Each such notice shall set forth: (a) the name and address of the stockholder who intends to make the nomination and of the person or persons to be nominated; (b) a representation that the stockholder is a holder of record of stock of the Corporation entitled to vote for the election of Directors on the date of such notice and intends to appear in person or by proxy at the meeting to nominate the person or persons specified in the notice; (c) a description of all arrangements or understandings between the stockholder and each nominee and any other person or persons (naming such person or persons) pursuant to which the nomination or nominations are to be made by the stockholder; (d) such other information regarding each nominee proposed by such stockholder as would be required to be included in a proxy statement filed pursuant to the proxy rules of the Securities and Exchange Commission, had the nominee been nominated, or intended to be nominated, by the Board of Directors; (e) the consent of each nominee to serve as a director of the Corporation if so elected; and (f) any direct or indirect pecuniary or economic interest in any capital stock or other security of the Corporation of such nominating stockholders, including, without limitation, any derivative instrument, swap, option, warrant, short interest, hedge, or profit-sharing arrangement.

     In the event that a person is validly designated as a nominee in accordance with this Section 2.11 and shall thereafter become unable or unwilling to stand for election to the Board of Directors, the Board of Directors or the stockholder who proposed such nominee, as the case may be, may designate a substitute nominee upon delivery, not fewer than five days prior to the date of the meeting for the election of such nominee, of a written notice to the Secretary setting forth such information regarding such substitute nominee as would have been required to be delivered to the Secretary pursuant to this Section 2.11 had such substitute nominee been initially proposed as a nominee. Such notice shall include a signed consent to serve as a director of the Corporation, if elected, of each such substitute nominee.

     If the chairman of the meeting for the election of Directors determines that a nomination of any candidate for election as a Director at such meeting was not made in accordance with the applicable provisions of this Section 2.11, such nomination shall be void; provided, however, that nothing in this Section 2.11 shall be deemed to limit any voting rights upon the occurrence of dividend arrearages provided to holders of Preferred Stock pursuant to the Preferred Stock designation for any series of Preferred Stock.

ARTICLE III

     Section 3.1 Committees of the Board of Directors. The Board of Directors, by a vote of a majority of the whole Board, may from time to time designate committees of the Board, with such lawfully delegable powers and duties as it thereby confers, to serve at the pleasure of the Board and shall, for those committees and any others provided for herein, elect a director or directors to serve as the member or members, designating, if it desires, other directors as alternate members who may replace any absent or disqualified member at any meeting of the committee. Any committee so designated may exercise the power and authority of the Board of Directors to declare a dividend, to authorize the issuance of stock or to adopt an agreement of merger or consolidation if the resolution which designates the committee or a supplemental resolution of the Board of Directors shall so provide. In the absence or disqualification of any member of any committee and any alternate member in his place, the member or members of the committee present at the meeting and not disqualified from voting, whether or not he or they constitute a quorum, may by unanimous vote appoint another member of the Board of Directors to act at the meeting in the place of the absent or disqualified member.

     Section 3.2 Conduct of Business. Each committee may determine the procedural rules for meeting and conducting its business and shall act in accordance therewith, except as otherwise provided herein or required by law. Adequate provision shall be made for notice to members of all meetings. If a quorum shall fail to attend any meeting, a majority of those present may adjourn the meeting to another place, date, or time, without further notice or waiver thereof. All matters shall be determined by a majority vote of the members present.

Neither the business nor the purpose of any meeting need be specified in such a waiver. Attendance of a person at a meeting shall constitute a waiver of notice for such meeting, except when the person attends a meeting for the express purpose of objecting, at the beginning of the meeting, to the transaction of any business because the meeting is not lawfully called or convened.

ARTICLE VIII
INDEMNIFICATION OF DIRECTORS AND OFFICERS

     Section 8.1 Right to Indemnification. Each person who was or is made a party or is threatened to be made a party to or is involved in any action, suit or proceeding, whether civil, criminal, administrative or investigative, or appellate (“Proceeding”), by reason of the fact that he or a person of whom he is the legal representative, is or was a director or officer, employee or agent of the Corporation or is or was serving at the request of the Corporation as a director or officer, employee or agent of another corporation, or of a 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, employee or agent or in any other capacity while serving as a director, officer, employee or agent, shall be indemnified and held harmless by the Corporation to the fullest extent authorized by 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, judgment, fines, ERISA excise taxes or penalties, amounts paid or to be paid in settlement and amounts expended in seeking indemnification granted to such person under applicable law, this Bylaw or any agreement with the Corporation) reasonably incurred or suffered by such person in connection therewith and such indemnification shall continue as to a person who has ceased to be a director, officer, employee or agent and shall inure to the benefit of his heirs, executors and administrators; provided, however, that, except as provided in Section 8.2, 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) was authorized by the Board of Directors of the Corporation; provided, however, that, if the Delaware General Corporation Law then so requires, the payment of such expenses incurred by a director or officer of the Corporation in his capacity as a director or officer (and not in any other capacity in which service was or is rendered by such person while a director or officer, including, without limitation, service to an employee benefit plan) 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, to repay all amounts so advanced if it should be determined ultimately that such director or officer is not entitled to be indemnified under this Section or otherwise.

     Section 8.2 Right of Indemnitee to Bring Suit. If a claim under Section 8.1 is not paid in full by the corporation within sixty (60) days after a written claim has been received by the corporation, except in the case of a claim for an advancement of expenses, in which case the applicable period shall be twenty (20) days, the indemnitee may at any time thereafter bring suit against the corporation to recover the unpaid amount of the claim. If successful in whole or in part in any such suit, or in a suit brought by the corporation to recover an advancement of expenses pursuant to the terms of an undertaking, the indemnitee shall be entitled to be paid also the expense of prosecuting or defending such suit. In (i) any suit brought by the indemnitee to enforce a right to indemnification hereunder (but not in a suit brought by the indemnitee to enforce a right to an advancement of expenses) it shall be a defense that, and (ii) in any suit by the corporation to recover an advancement of expenses pursuant to the terms of an undertaking the corporation shall be entitled to recover such expenses upon a final adjudication that, the indemnitee has not met the applicable standard of conduct set forth under the General Corporation Law of Delaware. Neither the failure of the corporation (including its board of directors, independent legal counsel, or its stockholders) to have made a determination prior to the commencement of such action that indemnification of the indemnitee is proper in the circumstances because he or she has met the applicable standard of conduct set forth in the General Corporation law of Delaware, nor an actual determination by the corporation (including its board of directors, independent legal counsel, or its stockholders) that the indemnitee has not met such applicable standard of conduct or, in the case of a suit brought by the indemnitee, be a defense to such a suit. In a suit brought by the indemnitee to enforce a right to indemnification or to an advancement of expenses hereunder, or by the corporation to recover an advancement of expenses pursuant to the terms of an undertaking, the burden of proving that the indemnitee is not entitled to be indemnified, or to such advancement of expenses, under this Article or otherwise shall be on the corporation.

     Section 8.3 Indemnification of Employees and Agents. The corporation may, to the extent authorized from time to time by the Board of Directors, grant rights to indemnification, and to the advancement of expenses to any employee or agent of the corporation to the fullest extent of the provisions of this Article with respect to the indemnification of and advancement of expenses to directors and officers of the corporation.

     Section 8.4 Non Exclusivity of Rights. The rights conferred on any person by Sections 8.1 and 8.2 shall not be exclusive of any other right which such persons may have or hereafter acquired under any statute, provisions of the Certificate of Incorporation, by law, agreement, vote of stockholders or disinterested directors or otherwise.

     Section 8.5 Indemnification Contracts. The Board of Directors is authorized to enter into a contract with any director or his affiliates, officer, employee or agent of the Corporation, or any person serving at the request of the Corporation as a director, officer, employee or agent of another corporation, partnership, joint venture, trust or other enterprise, including employee benefit plans, providing for indemnification rights equivalent to those provided for in this Article VIII.

     Section 8.6 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 any such expense, liability or loss, whether or not the Corporation would have the power to indemnify such person against such expenses, liability or loss under Delaware General Corporation Law.

     Section 8.7 Advance Payment of Expenses. Unless otherwise determined by (i) the Board of Directors, (ii) if more than half of the Directors are involved in a Proceeding by a majority vote of a committee of one or more distinguished Director(s) or (iii) if directed by the Board of Directors, by independent legal counsel in a written opinion, any indemnification extended to an officer or key employee pursuant to this Article VIII shall include payment by the Corporation or a subsidiary of the Corporation of expenses as the same are incurred in defending a Proceeding in advance of the final disposition of such Proceeding upon receipt of an undertaking by such officer or key employee seeking indemnification to repay such payment if such officer or key employee shall be adjudicated or determined not to be entitled to indemnification under this Article VIII.

     Section 8.8 Effect of Amendment. Any amendment, repeal or modification of any provision of this Article VIII by the stockholders or the directors of the Corporation shall not adversely affect any right or protection of a director or officer of the Corporation existing at the time of such amendment, repeal or modification.

     Section 8.9 Savings Clause. If this Article or any portion hereof shall be invalidated on any ground by any court of competent jurisdiction, then the Corporation shall nevertheless indemnify each director, officer, employee and agent of the Corporation as to costs, charges and expenses (including attorneys’ fees), judgments, fines and amounts paid in settlement with respect to any action, suit or proceeding, whether civil, criminal, administrative or investigative, including an action by or in the right of the Corporation, to the full extent permitted by any applicable portion of this Article that shall not have been invalidated and to the full extent permitted by applicable law.

ARTICLE IX
AMENDMENTS

     These Bylaws may be amended or repealed, and new Bylaws may be adopted, by the affirmative vote of a majority of the outstanding voting power of all of the then outstanding shares of the capital stock of the Corporation entitled to vote generally in the election of directors, voting together as a single class, or by vote of at least a majority of the number of directors of the Corporation then authorized, in the manner prescribed by the laws of the State of Delaware.
