ARTICLE 1

OFFICES

1.1     Registered Office . The registered office of the corporation shall be set forth in the certificate of incorporation of the corporation.

1.2     Other Offices . The corporation may also have offices at such other places, either within or without the State of Delaware, as the Board of Directors (the “Board”) may from time to time designate or the business of the corporation may require.

ARTICLE 2

MEETING OF STOCKHOLDERS

2.1     Place of Meeting . Meetings of stockholders may be held at such place, either within or without of the State of Delaware, as may be designated by or in the manner provided in these bylaws, or, if not so designated, at the registered office of the corporation or the principal executive offices of the corporation.

2.2     Annual Meeting . Annual meetings of stockholders shall be held each year at such date and time as shall be designated from time to time by the Board or the Chief Executive Officer and stated in the notice of the meeting. At each such annual meeting of stockholders, starting with the 2019 annual meeting of stockholders, each director to be elected by stockholders shall be elected by the vote of the majority of the votes cast at any meeting for the election of directors at which a quorum is present to hold office until the third succeeding annual meeting of stockholders after their election. The stockholders shall also transact such other business as may properly be brought before the meeting. For purposes of this bylaw regarding election of directors, a majority of votes cast shall mean that the number of shares voted “for” a director’s election exceeds 50% of the number of votes cast with respect to that director’s election. Votes cast shall include votes “against” a director’s election and shall exclude abstentions with respect to that director’s election. Notwithstanding the foregoing, in the event of a contested election of directors, directors shall be elected by the vote of a plurality of the votes cast at any meeting for the election of directors at which a quorum is present. For purposes of this bylaw regarding election of directors, a contested election shall mean any election of directors in which the number of candidates for election as directors exceeds the number of directors to be elected. If directors are to be elected by a plurality of the votes cast, stockholders shall not be permitted to vote against a nominee.

To be properly brought before the annual meeting, business must be (a) specified in the notice of meeting (or any supplement thereto) given by or at the direction of the Board or the

Chief Executive Officer, (b) otherwise properly brought before the meeting by or at the direction of the Board or the Chief Executive Officer, or (c) otherwise properly brought before the meeting by a stockholder of record. A motion related to business proposed to be brought before any stockholders’ meeting may be made by any stockholder entitled to vote if the business proposed is otherwise proper to be brought before the meeting. However, any such stockholder may propose business to be brought before a meeting only if such stockholder has given timely notice to the Secretary of the corporation in proper written form of the stockholder’s intent to propose such business. To be timely, the stockholder’s notice must be delivered by a nationally recognized courier service or mailed by first class United States mail, postage or delivery charges prepaid, and received at the principal executive offices of the corporation addressed to the attention of the Secretary of the corporation not earlier than ninety (90) days nor more than one hundred twenty (120) days in advance of the date the corporation’s proxy statement was released to the stockholders in connection with the previous year’s annual meeting of stockholders; provided, however, that in the event that no annual meeting was held in the previous year or the date of the annual meeting has been changed by more than thirty (30) days from the date contemplated at the time of the previous year’s proxy statement, notice by the stockholder must be received by the Secretary of the corporation not later than the close of business on the later of (x) the ninetieth (90th) day prior to such annual meeting and (y) the seventh (7th) day following the day on which public announcement of the date of such meeting is first made. For the purposes of these bylaws, “public announcement” shall mean disclosure in a press release reported by the Dow Jones News Service, Associated Press or a comparable national news service or in a document publicly filed by the corporation with the Securities and Exchange Commission. In no event shall the public announcement of an adjournment or postponement of an annual meeting commence a new time period (or extend any time period) for the giving of stockholder’s notice as described above. A stockholder’s notice to the Secretary shall set forth as to each matter the stockholder proposes to bring before the annual meeting (i) a brief description of the business desired to be brought before the annual 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), and the reasons for conducting such business at the annual meeting, (ii) the name and record address of the stockholder proposing such business and the beneficial owner, if any, on whose behalf the proposal is made, (iii) the class, series and number of shares of the corporation that are owned beneficially and of record by the stockholder and such beneficial owner, (iv) any material interest of the stockholder in such business, and (v) any other information that is required to be provided by the stockholder pursuant to Section 14 of the Securities Exchange Act of 1934 and the rules and regulations promulgated thereunder (collectively, the “1934 Act”) in such stockholder’s capacity as a proponent of a stockholder proposal.

Notwithstanding anything in these bylaws to the contrary, no business shall be conducted at the annual meeting except in accordance with the procedures set forth in this Section 2.2; provided, however, that nothing in this Section 2.2 shall be deemed to preclude discussion by any stockholder of any business properly brought before the annual meeting.

The Chairman of the Board (or such other person presiding at the meeting in accordance with these bylaws) shall, if the facts warrant, determine and declare to the meeting that business was not properly brought before the meeting in accordance with the provisions of this Section, and if he or she should so determine, he or she shall so declare to the meeting and any such business not properly brought before the meeting shall not be transacted.

2.3     Special Meetings . Special meetings of the stockholders may be called for any purpose or purposes, unless otherwise prescribed by statute or by the certificate of incorporation, by the Secretary only at the request of the Chairman of the Board, the Chief Executive Officer or by a resolution duly adopted by the affirmative vote of a majority of the Board. Such request shall state the purpose or purposes of the proposed meeting. Business transacted at any special meeting shall be limited to matters relating to the purpose or purposes stated in the notice of meeting.

2.4     Notice of Meetings . Except as otherwise provided by law, written notice of each meeting of stockholders, annual or special, stating the place, if any, date and time of the meeting, the means of remote communications, if any, by which stockholders and proxy holders may be deemed to be present in person and vote at such meeting, and, in the case of a special meeting, the purpose or purposes for which such special meeting is called, shall be given to each stockholder entitled to vote at such meeting not less than ten (10) nor more than sixty (60) days before the date of the meeting.

When a meeting is adjourned to another place, date or time, 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, if any, date, time and means of remote communications, if any, of the adjourned meeting shall be given in conformity herewith. At any adjourned meeting, any business may be transacted that might have been transacted at the original meeting.

2.5     List of Stockholders . The officer in charge of the stock ledger of the corporation or the transfer agent shall prepare and make, at least ten (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, for a period of at least ten days prior to the meeting, (i) on a reasonably accessible electronic network, provided that the information required to gain access to such list is provided with the notice of the meeting, or (ii) during ordinary business hours, at the principal place of business of the corporation. If the meeting is to be held at a place, then the list shall also 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 gain access to such list shall be provided with the notice of the meeting.

2.6     Organization and Conduct of Business . The Chairman of the Board or, in his or her absence, the Chief Executive Officer or President 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

3

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 of the meeting 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.

2.7     Quorum . Except where otherwise provided by law or the certificate of incorporation of the corporation or these bylaws, 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.

2.8     Adjournments . Any meeting of stockholders may be adjourned from time to time to any other time and to any other place at which a meeting of stockholders may be held under these bylaws, which time and place shall be announced at the meeting, by a majority of the stockholders present in person or represented by proxy at the meeting and entitled to vote, though less than a quorum, or, if no stockholder is present or represented by proxy, by any officer entitled to preside at or to act as secretary of such meeting, without notice other than announcement at the meeting, until a quorum shall be present or represented. At such adjourned meeting at which a quorum shall be present or represented, any business may be transacted which might have been transacted at the original meeting. If the adjournment is for more than thirty days, or if after the adjournment a new record date is fixed for the adjourned meeting, a notice of the adjourned meeting shall be given to each stockholder of record entitled to vote at the meeting.

2.9     Voting Rights . Unless otherwise provided in the certificate of incorporation of the corporation, each stockholder shall at every meeting of the stockholders be entitled to one vote for each share of the capital stock having voting power held by such stockholder.

2.10     Majority Vote . When a quorum is present at any meeting, the vote of the holders of a majority of the stock having voting power present in person or represented by proxy shall decide any question brought before such meeting, unless the question is one upon which by express provision of the statutes or of the certificate of incorporation of the corporation or of these bylaws, a different vote is required in which case such express provision shall govern and control the decision of such question.

2.11     Record Date for Stockholder Notice and Voting . For purposes of determining the stockholders entitled to notice of, or to vote at, any meeting of stockholders or any adjournment thereof, or entitled to receive payment of any dividend or other distribution or allotment of any rights, or entitled to exercise any right in respect of any change, conversion or exchange of stock or for the purpose of any other lawful action, the Board may fix, in advance, a record date, which shall not be more than sixty (60) days nor fewer than ten (10) days before the date of any such meeting nor more than sixty (60) days before any other action to which the record date relates. A determination of stockholders of record entitled to notice of or to vote at a meeting of stockholders shall apply to any adjournment of the meeting; provided, however, that the Board

4

may fix a new record date for the adjourned meeting. If the Board does not so fix a record date, the record date for determining stockholders entitled to notice of or to vote at a meeting of stockholders shall be at the close of business on the business day next preceding the day on which notice is given or, if notice is waived, at the close of business on the business day next preceding the day on which the meeting is held. The record date for determining stockholders for any other purpose shall be at the close of business on the day on which the Board adopts the resolution relating to such purpose.

2.12     Proxies . Each stockholder entitled to vote at a meeting of stockholders, or to express consent or dissent to corporate action in writing without a meeting, may authorize another person or persons to act for such stockholder by proxy, but no such proxy shall be voted or acted upon after three years from its date, unless the proxy provides for a longer period. All proxies must be filed with the Secretary of the corporation at the beginning of each meeting in order to be counted in any vote at the meeting. Subject to the limitation set forth in the last clause of the first sentence of this Section 2.12, a duly executed proxy that does not state that it is irrevocable shall continue in full force and effect unless (i) 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, or attendance at the meeting and voting in person by, the person executing the proxy, or (ii) 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.

2.13     Inspectors of Election . The corporation shall, in advance of any meeting of stockholders, appoint one or more inspectors of election to act at the meeting and make a written report thereof. The corporation may designate one or more persons to act as alternate inspectors to replace any inspector who fails to act. If no inspector or alternate is able to act at a meeting of stockholders, the person presiding at the meeting shall appoint one or more inspectors to act at the meeting. Each inspector, before entering upon the discharge of his or her duties, shall take and sign an oath faithfully to execute the duties of inspector with strict impartiality and according to the best of his or her ability.

2.14     Action Without a Meeting . No action required or permitted to be taken at any annual or special meeting of the stockholders of the corporation may be taken without a meeting and the power of the stockholders to consent in writing, without a meeting, to the taking of any action is specifically denied.

DIRECTORS

3.1     Number, Election, Tenure and Qualifications . The number of directors that shall constitute the entire Board initially shall be five (5); provided, however, that the number of directors that shall constitute the entire Board shall be fixed from time to time by resolution adopted by a majority of the entire Board.

The directors shall be elected at the annual meetings of the stockholders, except as otherwise provided in Section 3.2, and each director elected shall hold office until such director’s successor is elected and qualified, unless sooner displaced.

To be timely, a stockholder’s notice shall be delivered by a nationally recognized courier service or mailed by first class United States mail, postage or delivery charges prepaid, and received at the principal executive offices of the corporation addressed to the attention of the Secretary of the corporation not earlier than ninety (90) days nor more than one hundred twenty (120) days in advance of the date the corporation’s proxy statement was released to the stockholders in connection with the previous year’s annual meeting of stockholders; provided, however, that in the event that no annual meeting was held in the previous year or the date of the annual meeting has been changed by more than thirty (30) days from the date contemplated at the time of the previous year’s proxy statement, notice by the stockholder must be received by the Secretary of the corporation not later than the close of business on the later of (x) the ninetieth (90th) day prior to such annual meeting and (y) the seventh (7th) day following the day on which public announcement of the date of such meeting is first made. Such stockholder’s notice to the Secretary shall set forth (a) as to each person whom the stockholder proposes to nominate for election or reelection as a director, (i) the name, age, business address and residence address of the person, (ii) the principal occupation or employment of the person, (iii) the class, series and number of shares of capital stock of the corporation that are owned beneficially by the person, (iv) a statement as to the person’s citizenship, (v) and a written statement of the person that such person, if elected, intends to tender, promptly following such person’s election or reelection, an irrevocable resignation effective upon such person’s failure to receive the required vote for reelection at the next meeting at which such person would face reelection and upon acceptance of such resignation by the Board, and (vi) any other information relating to the person that is required to be disclosed in solicitations for proxies for election of directors pursuant to Section 14 of the 1934 Act, and (b) as to the stockholder giving the notice, (i) the name and record address of the stockholder and (ii) the class, series and number of shares of capital stock of the corporation that are owned beneficially by the stockholder. The corporation may require any 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 director of the corporation. No person shall be eligible for election as a director of the corporation unless nominated in accordance with the procedures set forth herein.

In connection with any annual meeting of the stockholders (or, if and as applicable, any special meeting of the stockholders), the Chairman of the Board (or such other person presiding at such meeting in accordance with these bylaws) shall, if the facts warrant, determine and declare to the meeting that a nomination was not made in accordance with the foregoing procedure, and if he or she should so determine, he or she shall so declare to the meeting and the defective nomination shall be disregarded.

Sole power to fill vacancies and newly created directorships resulting from any increase in the authorized number of directors shall be vested in the Board as provided in the certificate of incorporation of the corporation, and each director so chosen shall hold office until the next annual election at which the term of the class to which they have been elected expires and until such director’s successor is duly elected and qualified or until such director’s earlier resignation, removal from office, death or incapacity. If there are no directors in office, then an election of directors may be held in the manner provided by statute. In the event of a vacancy in the Board, the remaining directors, except as otherwise provided by law or these bylaws, may exercise the powers of the full board until the vacancy is filled.

3.3     Resignation and Removal . Any director may resign at any time upon written notice to the corporation at its principal place of business or to the Chief Executive Officer or the Secretary. Such resignation shall be effective upon receipt of such notice unless the notice specifies such resignation to be effective at some other time or upon the happening of some other event. Any director or the entire Board may be removed, but only for cause, by the holders of a majority of the shares then entitled to vote at an election of directors, unless otherwise specified by law or the certificate of incorporation of the corporation.

3.4     Composition . The corporation shall use commercially reasonable efforts to ensure that a majority of the members of the Board qualify as “independent directors” (each an “Independent Director”) under the then current rules and regulations of the United States Securities and Exchange Commission and the primary stock exchange, stock market or quotation system on which the corporation’s stock is then listed or quoted, as applicable.

3.5     Powers . The business of the corporation shall be managed by or under the direction of the Board, which may exercise all such powers of the corporation and do all such lawful acts and things as are not by statute or by the certificate of incorporation of the corporation or by these bylaws directed or required to be exercised or done by the stockholders.

3.6     Chairman of the Board . If the Board appoints a Chairman of the Board, such Chairman shall, when present, preside at all meetings of the stockholders and the Board.

3.10     Special Meetings . Special meetings of the Board may be called by the Chairman of the Board, the Chief Executive Officer, the President or the Secretary, or on the written request of two or more directors, or by one director in the event that there is only one director in office. Notice of the time and place, if any, of special meetings shall be delivered personally or by telephone to each director, or sent by first-class mail or commercial delivery service, facsimile transmission, or by electronic mail or other electronic means, charges prepaid, sent to such director’s business or home address as they appear upon the records of the corporation. In case such notice is mailed, it shall be deposited in the United States mail at least four (4) days prior to the time of holding of the meeting. In case such notice is delivered personally or by telephone or by commercial delivery service, facsimile transmission, or electronic mail or other electronic means, it shall be so delivered at least twenty-four (24) hours prior to the time of the holding of the meeting. A notice or waiver of notice of a meeting of the Board need not specify the purposes of the meeting.

3.11     Quorum, Action at Meeting, Adjournments . At all meetings of the Board, a majority of directors then in office, but in no event less than one-third (1/3) of the entire Board, shall constitute a quorum for the transaction of business and the act of a majority of the directors present at any meeting at which there is a quorum shall be the act of the Board, except as may be otherwise specifically provided by law or by the certificate of incorporation of the corporation. For purposes of this Section 3.11, the term “entire Board” shall mean the number of directors last fixed by directors in accordance with these bylaws; provided, however, that if fewer than all the number of directors so fixed have been elected (by the stockholders or the Board), the “entire Board” shall mean the greatest number of directors so elected to hold office at any one time pursuant to such authorization. If a quorum shall not be present at any meeting of the board of directors, a majority of the directors present thereat may adjourn the meeting from time to time, without notice other than announcement at the meeting, until a quorum shall be present.

3.12     Action Without Meeting . Unless otherwise restricted by the certificate of incorporation of the corporation or these bylaws, any action required or permitted to be taken at any meeting of the Board or of any committee thereof may be taken without a meeting, if all members of the Board or committee, as the case may be, consent thereto in writing or by electronic transmission, and the writing or writings or electronic transmission or transmissions are filed with the minutes of proceedings of the Board or committee.

3.13     Telephone Meetings . Unless otherwise restricted by the certificate of incorporation of the corporation or these bylaws, any member of the Board or any committee thereof may participate in a meeting of the Board or of any committee, as the case may be, by means of conference telephone or by any form of communications equipment by means of which all persons participating in the meeting can hear each other, and such participation in a meeting shall constitute presence in person at the meeting.

3.14     Committees . The Board may, by resolution passed by a majority of the whole Board, designate one or more committees, each committee to consist of one or more of the directors of the corporation. The Board may designate one or more directors as alternate

8

members of any committee, who may replace any absent or disqualified member at any meeting of the committee. In the absence or disqualification of a member of a committee, the member or members present at any meeting and not disqualified from voting, whether or not the member or members present constitute a quorum, may unanimously appoint another member of the Board to act at the meeting in the place of any such absent or disqualified member. Any such committee, to the extent provided in the resolution of the Board, shall have and may exercise all the powers and authority of the Board in the management of the business and affairs of the corporation, and may authorize the seal of the corporation to be affixed to all papers which may require it; but no such committee shall have the power or authority in reference to (i) approving or adopting, or recommending to the stockholders, any action or matter expressly required by the DGCL to be submitted to stockholders for approval or (ii) adopting, amending or repealing any of these bylaws. Such committee or committees shall have such name or names as may be determined from time to time by resolution adopted by the Board. Each committee shall keep regular minutes of its meetings and make such reports to the Board as the Board may request. Except as the Board may otherwise determine, any committee may make rules for the conduct of its business, but unless otherwise provided by the directors or in such rules, its business shall be conducted as nearly as possible in the same manner as is provided in these bylaws for the conduct of its business by the Board.

3.15     Fees and Compensation of Directors . Unless otherwise restricted by the certificate of incorporation of the corporation or these bylaws, the Board shall have the authority to fix the compensation of directors. The directors may be paid their expenses, if any, of attendance at each meeting of the Board and may be paid a fixed sum for attendance at each meeting of the Board or a stated salary as director. No such payment shall preclude any director from serving the corporation in any other capacity and receiving compensation therefor. Members of special or standing committees may be allowed like compensation for attending committee meetings.

ARTICLE 6

INDEMNIFICATION AND INSURANCE

6.1     Indemnification .

(a)    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 (hereinafter a “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 any predecessor) or is or was serving at the request of the corporation (or any predecessor) as a director, officer, employee or agent of another corporation or of a partnership, joint venture, trust, employee benefit plan sponsored or maintained by the corporation, or other enterprise (or any predecessor of any of such entities), 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 General Corporation Law of the State of Delaware, as the same exists or may hereafter be amended (but, in the case of any such

12

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 expense, liability and loss (including attorneys’ 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 except as provided in Section 6.1(c), the corporation shall indemnify any such person seeking indemnification in connection with a proceeding (or part thereof) initiated by such person only if such proceeding (or part thereof) was authorized by the Board. The right to indemnification conferred in this Section 6.1 shall be a contract right.

(b)    To obtain indemnification under this Section 6.1, a claimant shall submit to the corporation a written request, including therein or therewith such documentation and information as is reasonably available to the claimant and is reasonably necessary to determine whether and to what extent the claimant is entitled to indemnification. Upon written request by a claimant for indemnification pursuant to the preceding sentence, a determination, if required by applicable law, with respect to the claimant’s entitlement thereto shall be made as follows: (i) if requested by the claimant, by Independent Counsel (as hereinafter defined), or (ii) if no request is made by the claimant for a determination by Independent Counsel, (A) by the Board by a majority vote of the Disinterested Directors (as hereinafter defined), even though less than a quorum, or (B) by a committee of Disinterested Directors designated by majority vote of the Disinterested Directors, even though less than a quorum, or (C) if there are no Disinterested Directors or the Disinterested Directors so direct, by Independent Counsel in a written opinion to the Board, a copy of which shall be delivered to the claimant, or (D) if a quorum of Disinterested Directors so directs, by the stockholders of the corporation. In the event the determination of entitlement to indemnification is to be made by Independent Counsel at the request of the claimant, the Independent Counsel shall be selected by the Board unless there shall have occurred within two years prior to the date of the commencement of the proceeding for which indemnification is claimed a Change of Control (as hereinafter defined), in which case Independent Counsel shall be selected by the claimant unless the claimant shall request that such selection be made by the Board. If it is so determined that the claimant is entitled to indemnification, payment to the claimant shall be made within ten (10) days after such determination.

(c)    If a claim for the indemnification under this Section 6.1 is not paid in full by the corporation within thirty (30) days after a written claim pursuant to Section 6.1(b) has been received by the corporation, the claimant may at 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. It shall be a defense to any such action (other than an action brought to enforce a claim for expenses incurred in defending any proceeding in advance of its final disposition where the required undertaking, if any is required, has been tendered to the corporation) that the claimant has not met the standard of conduct that makes it permissible under the General Corporation Law of the State of Delaware for the corporation to indemnify the claimant for the amount claimed, but the burden of proving such defense shall be on the corporation. Neither the failure of the corporation (including its board of directors, Independent Counsel or stockholders) to have made a determination prior to the commencement of such action that indemnification of the claimant is proper in the circumstances because he or she has met the applicable standard of conduct set forth in the

13

General Corporation Law of the State of Delaware, nor an actual determination by the corporation (including its board of directors, Independent Counsel or stockholders) that the claimant has not met such applicable standard of conduct, shall be a defense to the action or create a presumption that the claimant has not met the applicable standard of conduct.

(d)    If a determination shall have been made pursuant to this Section 6.1 that the claimant is entitled to indemnification, the corporation shall be bound by such determination in any judicial proceeding commenced pursuant to Section 6.1(c). The corporation shall be precluded from asserting in any judicial proceeding commenced pursuant to the Section 6.1(c) that the procedures and presumptions of this Article 6 are not valid, binding and enforceable and shall stipulate in such proceeding that the corporation is bound by all the provisions of this Article 6.

6.2     Advance Payment . The right to indemnification under this Article 6 shall include the right to be paid by the corporation the expenses incurred in defending any such proceeding in advance of its final disposition, such advances to be paid by the corporation within twenty (20) days after the receipt by the corporation of a statement or statements from the claimant requesting such advance or advances from time to time; provided, however, that if the General Corporation Law of the State of Delaware requires, the payment of such expenses incurred by a director or officer in his or her 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 a 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 shall ultimately be determined that such director or officer is not entitled to be indemnified under Section 6.1 or otherwise.

Notwithstanding the foregoing, unless otherwise determined pursuant to Section 6.3, no advance shall be made by the corporation to an officer of the corporation (except by reason of the fact that such officer is or was a director of the corporation, in which event this paragraph shall not apply) in any action, suit or proceeding, whether civil, criminal, administrative or investigative, if a determination is reasonably and promptly made (i) by the Board by a majority vote of the Disinterested Directors, even though less than a quorum, or (B) by a committee of Disinterested Directors designated by majority vote of the Disinterested Directors, even though less than a quorum, or (C) if there are no Disinterested Directors or the Disinterested Directors so direct, by Independent Counsel in a written opinion to the Board, a copy of which shall be delivered to the claimant, that the facts known to the decision-making party at the time such determination is made demonstrate clearly and convincingly that such person acted in bad faith or in a manner that such person did not believe to be in or not opposed to the best interests of the corporation.

6.3     Non-Exclusivity and Survival of Rights; Amendments . The right to indemnification and the payment of expenses incurred in defending a proceeding in advance of its final disposition conferred in this Article 6 shall not be deemed exclusive of any other right which any person may have or hereafter acquire under any statute, provision of the certificate of incorporation of the corporation, bylaws, agreement, vote of stockholders or Disinterested Directors or otherwise, both as to action in such person’s official capacity and as to action in

14

another capacity while holding such office, and shall continue as to a person who has ceased to be a director, officer, employee or agent of the corporation and shall inure to the benefit of the heirs, executors and administrators of such a person. Any repeal or modification of the provisions of this Article 6 shall not in any way diminish or adversely affect the rights of any director, officer, employee or agent of the corporation hereunder in respect of any occurrence or matter arising prior to any such repeal or modification.

6.4     Insurance . The corporation may purchase and maintain insurance on behalf of any person who is or was a director, officer, employee or agent of the corporation, or is or was serving at the request of the corporation as a director, officer, employee or agent of another corporation, partnership, joint venture, trust, employee benefit plan or other enterprise against any expense, liability or loss asserted against such person and incurred by such person in any such capacity, or arising out of such person’s status as such, whether or not the corporation would have the power to indemnify such person against such liability under the provisions of the General Corporation Law of State of Delaware.

6.5     Severability . If any word, clause, provision or provisions of this Article 6 shall be held to be invalid, illegal or unenforceable for any reason whatsoever: (i) the validity, legality and enforceability of the remaining provisions of this Article 6 (including, without limitation, each portion of any section or paragraph of this Article 6 containing any such provision held to be invalid, illegal or unenforceable, that is not itself held to be invalid, illegal or unenforceable) shall not in any way be affected or impaired thereby; and (ii) to the fullest extent possible, the provisions of this Article 6 (including, without limitation, each such portion of any section or paragraph of this Article 6 containing any such provision held to be invalid, illegal or unenforceable) shall be construed so as to give effect to the intent manifested by the provision held invalid, illegal or unenforceable.

Upon receipt of proper transfer instructions from the registered owner of uncertificated share, such uncertificated shares shall be canceled and issuance of new equivalent uncertificated shares or certificated shares shall be made to the person entitled thereto and the transaction shall be recorded upon the books of the corporation.

(a)    the material facts as to such director’s or officer’s relationship or interest and as to the contract or transaction are disclosed or are known to the Board or the committee, and the Board or committee in good faith authorizes the contract or transaction by the affirmative votes of a majority of the disinterested directors, even though the disinterested directors be less than a quorum; or
