ARTICLE II

CORPORATE GOVERNANCE MATTERS

2.1 Election of Directors.

(a) At the Closing Date, the Company and the Shareholders shall take all necessary action to cause the Board to be comprised of eleven (11) directors. The foregoing directors shall be divided into three classes of directors, with one class elected at the annual general meeting each year.

(b) Following the Closing Date, the Shareholders shall have the right, but not the obligation, to designate, and the individuals nominated for election as Directors by or at the direction of the Board or a duly-authorized committee thereof shall include, a number of individuals such that, following the election of any Directors and taking into account any Director continuing to serve as such without the need for re-election, the number of Shareholder Designees (as defined below) serving as Directors of the Company will be equal to: (i) six (6), if the Shareholder Entities Beneficially Own, directly or indirectly, at least 50% of the total voting power of the then outstanding Ordinary Shares in issue as of the record date for such meeting; (ii) three (3), if the Shareholder Entities Beneficially Own, directly or indirectly, at least 25% (but less than 50%) of the total voting power of the then outstanding Ordinary Shares in issue as of the record date for such meeting; and (iii) one (1), if the Shareholder Entities Beneficially Own, directly or indirectly, at least 5% (but less than 25%) of the total voting power of the then outstanding Ordinary Shares in issue as of the record date for such meeting. The Shareholders shall lose all nomination rights if the Shareholder Entities Beneficially Own, directly or indirectly, less than 5% of the total voting power of the outstanding Ordinary Shares. For so long as the Directors on the Board are divided into three classes, such Shareholder Designees shall be apportioned among such classes so as to maintain the number of Shareholder Designees in each class as nearly equal as possible.

(c) If at any time the Shareholders have designated fewer than the total number of individuals that the Shareholders are then entitled to designate pursuant to Section 2.1(a) hereof, the Shareholders shall have the right, at any time and from time to time, to designate such additional individuals which they are entitled to so designate, in which case, any individuals nominated by or at the direction of the Board or any duly-authorized committee thereof for election as Directors to fill any vacancy on the Board shall include such designees, and the Company shall use its best efforts to (x) effect the election of such additional designees, whether by increasing the size of the Board or otherwise, and (y) cause the election of such additional designees to fill any such newly-created vacancies or to fill any other existing vacancies. Each such individual whom the Shareholders shall actually designate pursuant to this Section 2.1 and who is thereafter elected and qualifies to serve as a Director shall be referred to herein as a “Shareholder Designee.”

(d) In the event that a vacancy is created at any time by the death, disability, retirement, removal or resignation of any Shareholder Designee, any individual nominated by or at the direction of the Board or any duly-authorized committee thereof to fill such vacancy shall be, and the Company shall use its best efforts to cause such vacancy to be filled, as soon as possible, by a new designee of the Shareholders, and the Company shall take or cause to be taken, to the fullest extent permitted by Law, at any time and from time to time, all actions necessary to accomplish the same. The Shareholders have the right to remove any of their Shareholder Designees, and the exclusive right to fill any vacancy so created by such removal or resignation of such Shareholder Designee, with any such replacement to stand for election at the next annual general meeting.

(e) The Company shall, to the fullest extent permitted by Law, include in the slate of nominees recommended by the Board at any meeting of shareholders called for the purpose of electing directors (or consent in lieu of meeting), the persons designated pursuant to this Section 2.1 and use its best efforts to cause the election of each such designee to the Board, including nominating each such individual to be elected as a Director as provided herein, recommending such individual’s election and soliciting proxies or consents in favor thereof. In the event that any Shareholder Designee shall fail to be elected to the Board at any meeting of shareholders called for the purpose of electing directors (or consent in lieu of meeting), the Company shall use its best efforts to cause such Shareholder Designee (or a new designee of the Sponsor) to be elected to the Board, as soon as possible, and the Company shall take or cause to be taken, to the fullest extent permitted by Law, at any time and from time to time, all actions necessary to accomplish the same, including, without limitation, actions to effect an increase in the Total Number of Directors.

(f) In addition to any vote or consent of the Board or the shareholders of the Company required by applicable Law or the articles of association or other organizational document of the Company, and notwithstanding anything to the contrary in this Agreement, for so long as this Agreement is in effect, any action by the Board to increase or decrease the Total Number of Directors shall require the prior written consent of the Shareholders, delivered in accordance with Section 5.13 hereof.

(g) The Company shall use reasonable endeavors to procure that the Board authorizes, in accordance with the Company’s articles of association, any direct or indirect interest of a Shareholder Designee that conflicts, or may possibly conflict, with the interests of the Company and that arises solely in consequence of such Shareholder Designee being a director, manager, officer, employee or member of, or partner in, any of the Shareholder Entities. The provisions of this Section 2.1(g) are not intended to apply, and do not apply, to any actual or possible conflict that may arise in consequence of such Shareholder Designee being a director, officer or employee of any other entity that is an operating Subsidiary of any of the Shareholder Entities.

2.2 Committees. For so long as this Agreement is in effect, the Company shall take all reasonable actions within its control at any given time so as to cause to be appointed to any committee of the Board a number of Shareholder Designees such that the number of Shareholder Designees serving on any such committee is proportionate (rounding up to the next whole director)

to the number of directors that the Shareholders are entitled to designate to the Board under this Agreement, to the extent such directors are permitted to serve on such committees under the applicable rules and regulations of the U.S. Securities and Exchange Commission or the applicable stock exchange on which the Class A Ordinary Shares are listed. It is understood by the parties hereto that the Shareholders shall not be required to have their directors represented on any committee and any failure to exercise such right in this Section 2.2 in a prior period shall not constitute any waiver of such right in a subsequent period.

2.3 Compensation. Except to the extent the Shareholders may otherwise notify the Company, the Shareholder Designees shall be entitled to compensation consistent with the compensation received by other non-employee Directors, including any fees and equity awards, provided that (x) to the extent any Director compensation is payable in the form of equity awards, at the election of a Shareholder Designee, in lieu of any equity award, such compensation shall be paid in an amount of cash equal to the value of the equity award as of the date of the award, with any such cash subject to the same vesting terms, if any, as the equity awarded to other Directors and (y) at the election of a Shareholder Designee, any Director compensation (whether cash, equity awards and/or cash in lieu of equity as may be designated by the electing Shareholder Designee) shall be paid to a Shareholder or an Affiliate thereof specified by such Shareholder Designee rather than to such Shareholder Designee. If the Company adopts a policy that Directors own a minimum amount of equity in the Company, Shareholder Designees shall not be subject to such policy.

2.4 Advancement of Expenses. The Company shall advance expenses for each Shareholder Designee for all reasonable and documented out-of-pocket expenses incurred in connection with such designee’s participation in the meetings of the Board or any committee of the Board, including all reasonable and documented travel, lodging and meal expenses.

2.5 Indemnification Priority. The Company hereby acknowledges that, in addition to the rights provided to each Shareholder Designee or other indemnified person covered by any such indemnity insurance policy (any such Person, an “Indemnitee”) or any indemnification agreement that such Indemnitee may enter into with the Company from time to time (the “Indemnification Agreements”), the Indemnitees may have certain rights to indemnification, advancement of expenses and/or insurance provided by the Sponsor, the Shareholder Entities or one or more of their respective Affiliates (collectively, the “Fund Indemnitors”). Notwithstanding anything to the contrary in any of the Indemnification Agreements or this Agreement, the Company hereby agrees that, to the fullest extent permitted by Law, with respect to its indemnification and advancement obligations to the Indemnitees under the Indemnification Agreements, this Agreement or otherwise, the Company (i) is the indemnitor of first resort (i.e., its and its insurers’ obligations to advance expenses and to indemnify the Indemnitees are primary and any obligation of the Fund Indemnitors or their insurers to advance expenses or to provide indemnification for the same expenses or liabilities incurred by any of the Indemnitees is secondary and excess), (ii) shall be required to advance the full amount of expenses incurred by each Indemnitee and shall be liable for the full amount of all losses of each Indemnitee or on his, her or its behalf to the extent legally permitted and as required by this Agreement and the Indemnification Agreements, without regard to any rights such Indemnitees may have against the Fund Indemnitors or their insurers, and (iii) irrevocably waives and relinquishes, and releases the Fund Indemnitors and such insurers from, any and all claims against the Fund Indemnitors or such insurers for contribution, subrogation or any other recovery of any kind in respect thereof. In furtherance and not in limitation of the

foregoing, the Company agrees that in the event that any Fund Indemnitor or its insurer should advance any expenses or make any payment to any Indemnitee for matters subject to advancement or indemnification by the Company pursuant to this Agreement or otherwise, the Company shall promptly reimburse such Fund Indemnitor or insurer and that such Fund Indemnitor or insurer shall be subrogated to all of the claims or rights of such Indemnitee under the Indemnification Agreements, this Agreement or otherwise, including to the payment of expenses in an action to collect. The Company agrees that any Fund Indemnitor or insurer thereof not a party hereto shall be an express third party beneficiary of this Section 2.5, able to enforce such clause according to its terms as if it were a party hereto. Nothing contained in the Indemnification Agreements is intended to limit the scope of this Section 2.5 or the other terms set forth in this Agreement or the rights of the Fund Indemnitors or their insurers hereunder.

2.6 Other Rights of Shareholder Designees. Except as provided in Sections 2.3, 2.4 and 2.5, each Shareholder Designee serving on the Board shall be entitled to the same rights and privileges applicable to all other members of the Board generally or to which all such members of the Board are entitled. In furtherance of the foregoing, the Company shall indemnify, exculpate, and advance fees and expenses of the Shareholder Designees (including by entering into an indemnification agreement in a form substantially similar to the Company’s form director indemnification agreement) and provide the Shareholder Designees with director and officer insurance to the same extent it indemnifies, exculpates, reimburses and provides insurance for the other members of the Board pursuant to the charter, articles of association or other organizational document of the Company, applicable Law or otherwise.

(e) For so long as the VCOC Investor, directly or through one or more subsidiaries, continues to hold any Ordinary Shares (or other securities of the Company into which such Ordinary Shares may be converted or for which such Ordinary Shares may be exchanged) and upon the written request of such VCOC Investor, without limitation or prejudice of any the rights provided to the Shareholder Entities hereunder, the Company shall, with respect to each such VCOC Investor, furnish and deliver a letter covering the matters set forth in Sections 3.3(a), 3.3(b), 3.3(c) and 3.3(d) hereof in a form and substance reasonably satisfactory to such VCOC Investor.

(f) In the event a VCOC Investor is an Affiliate of a Shareholder Entity, as described in Section 3.3(a) above, such affiliated entity shall be afforded the same rights with respect to the Company and afforded to the Shareholder Entity under this Section 3.3 and shall be treated, for such purposes, as a third party beneficiary hereunder.

3.4 Confidentiality. Each Shareholder agrees that it will, and will direct its designated representatives to, keep confidential and not disclose any Confidential Information; provided, however, that such Shareholder and its designated representatives may disclose Confidential Information to the other Shareholders, to the Shareholder Designees and to (a) its and its affiliates’ attorneys, accountants, consultants, insurers, financing sources and other advisors in connection with such Shareholder’s investment in the Company, (b) any Person, including a prospective purchaser of Ordinary Shares, as long as such Person has agreed to maintain the confidentiality of such Confidential Information, (c) any of such Shareholder’s or its respective Affiliates’ partners, members, stockholders, directors, officers, employees or agents in the ordinary course of business or in connection with such Shareholder’s investment in the Company (the Persons referenced in clauses (a), (b) and (c), a Shareholder’s “designated representatives”) or (d) as the Company may otherwise consent in writing; provided, further, however, that each Shareholder agrees to be responsible for any breaches of this Section 3.4 by such Shareholder’s designated representatives.

3.5 Information Sharing. Each party hereto acknowledges and agrees that Shareholder Designees may share any information concerning the Company and its Subsidiaries received by them from or on behalf of the Company or its designated representatives with each Shareholder and its designated representatives (subject to such Shareholder’s obligation to maintain the confidentiality of Confidential Information in accordance with Section 3.4).
