(i) up to three designees (or if the size of the Board is increased, a majority (i.e. more than 50%) of the Total Number of Directors, rounded upward to the nearest whole number), so long as the Shareholders’ and their Affiliates’ Aggregate Voting Power of Shares (as determined on a Common Equivalents basis) continues to be at least 25% of the total voting power of all Shares (as determined on a Common Equivalents basis),

4

(ii) up to two designees (or if the size of the Board is increased, 25% of the Total Number of Directors, rounded upward to the nearest whole number), so long as the Shareholders’ and their Affiliates’ Aggregate Voting Power of Shares (as determined on a Common Equivalents basis) continues to be at least 10% of the total voting power of all Shares (as determined on a Common Equivalents basis), and

(iii) up to one designee (or if the size of the Board is increased, 10% of the Total Number of Directors, rounded upward to the nearest whole number), so long as the Shareholders’ and their Affiliates’ Aggregate Voting Power of Shares (as determined on a Common Equivalents basis) is (x) less than 10% of the total voting power of all Shares and (y) at least 5% of the total voting power of all Shares, each as determined on a Common Equivalents basis.

In the event that the Shareholders have nominated less than the total number of designees the Shareholders are entitled to nominate pursuant to this Section 2.01(b), the Shareholders shall have the right, at any time, to nominate such additional designees to which they are entitled, in which case the Shareholders and the Company shall take, or cause to be taken, all Necessary Action to (A) increase the size of the Board as required to enable the Shareholders to so nominate such additional designees and (B) appoint such additional designees nominated by the Shareholders to such newly created directorships. Each specified Shareholder designee shall be referred to hereinafter as a “Shareholder Designee.”

(c) In accordance with the Articles of Association, from and after the date on which the Shareholders (and/or their respective Affiliates) no longer constitute a group that beneficially owns more than fifty percent of the outstanding voting power of the Company (the “Classifying Date”), the Company shall cause the Directors to be, and the Directors shall be, divided into three classes designated Class I, Class II and Class III. Each class of Directors shall consist, as nearly as possible, of one third of the total number of Directors constituting the entire Board. The Board is hereby authorized to assign members of the Board in office at the Classifying Date to such classes. Each Director shall serve for a term ending on the date of the third annual general meeting of shareholders next following the annual general meeting of shareholders at which such Director was elected, provided that Directors initially designated as Class I Directors (“Class I Directors”) shall serve for a term ending on the date of the first annual general meeting of shareholders following the Classifying Date, Directors initially designated as Class II Directors (“Class II Directors”) shall serve for a term ending on the second annual general meeting of shareholders following the Classifying Date, and Directors initially designated as Class III Directors (“Class III Directors”) shall serve for a term ending on the date of the third annual general meeting of shareholders following the Classifying Date. The Shareholder Designees shall be allocated to the longest duration classes, unless otherwise determined by the Shareholders.

(d) The Company agrees, to the fullest extent permitted by applicable law (including with respect to any applicable fiduciary duties under Cayman Islands law), to take all Necessary Action to effectuate the above by; (A) including the persons designated pursuant to this Section 2.01 in the slate of nominees recommended by the

5

Board for election at any meeting of stockholders called for the purpose of electing Directors, (B) nominating and recommending each such individual to be elected as a Director as provided herein, (C) soliciting proxies or consents in favor thereof, and (D) without limiting the foregoing, otherwise using its reasonable best efforts to cause such nominees to be elected to the Board, including providing at least as high a level of support for the election of such nominees as it provides to any other individual standing for election as a Director.

(e) At any time the number of Directors that the Shareholders are entitled to designate pursuant to this Section 2.01 is less than the number of Shareholder Directors on the Board, the Shareholders shall cause the required number of Directors to resign from the Board or not stand for reelection on or prior to the Company’s next general meeting of shareholders at which Directors of the Company are to be elected, and any vacancies resulting from such resignation shall be filled by the Board in accordance with the Governing Documents, the rules of the U.S. Securities Exchange Commission (the “SEC”) and the rules of the Exchange then in effect.

(f) For the avoidance of doubt, the rights granted to the Shareholders to designate members of the Board are additive to, and not intended to limit in any way, the rights that the Shareholders or any of their respective Affiliates may have to nominate, elect or remove directors under the Governing Documents or Cayman Islands law.

Section 2.02. Removal. So long as a Shareholder is entitled to designate one or more nominees pursuant to Section 2.01 such Shareholder shall have the right to remove any such director (with or without cause), from time to time and at any time, from the Board, exercisable upon written notice to the Company, and the Company shall take all Necessary Action to cause such removal.

Section 2.03. Vacancies. In the event that a vacancy is created on the Board at any time by the death, disability, resignation or removal (whether by the Shareholders or otherwise in accordance with the Governing Documents, as either may be amended or restated from time to time) of a Shareholder Director, the Shareholders entitled to appoint such Shareholder Director shall be entitled to designate an individual to fill the vacancy so long as the total number of persons that will serve on the Board as designees of such Shareholders immediately following the filling of such vacancy will not exceed the total number of persons such Shareholder is entitled to designate pursuant to Section 2.01 on the date of such replacement designation. The Company and the Shareholders shall take all Necessary Action to cause such replacement designee to become a member of the Board.

Subject to the provisions of this Agreement, the Board may nominate additional Directors to the Board, or fill any vacancy on the Board, pursuant to the terms of the Governing Documents.

Section 2.04. Board Expenses. The Company shall pay all reasonable out-of-pocket expenses incurred by each director in connection with attending regular and special meetings of the Board and any committee thereof, and any such meetings of the board of directors of any Subsidiary of the Company and any committee thereof.
