Section 2.4. Grant of Irrevocable Proxy; Appointment of Proxy.

(a) Each Founder and the Investor further agrees not to take any other actions as a stockholder of the Company or in any other capacity intended to or reasonably likely to, directly or indirectly, circumvent, avoid or nullify the voting arrangements required by this Article II.

(b) Each Founder hereby irrevocably appoints the Investor and any designee thereof as its proxy and attorney-in-fact (with full power of substitution), to vote or cause to be voted (including by proxy, if applicable) such Founder’s Founder Shares (i) in accordance with Section 2.1 above, and (ii) subject to and commencing upon the Closing, in accordance with Section 2.3(a)(iii) above, in each case at any annual or special meeting of the shareholders of the Company, however called, including any adjournment or postponement thereof, at which any of the matters described in Section 2.1 or Section 2.3(a)(iii) above is to be considered. Each Founder represents that all proxies, powers of attorney, instructions or other requests given by such Founder prior to the execution of this Agreement in respect of the voting of such Founder’s Founder Shares, if any, are not irrevocable and each Founder hereby revokes any and all previous proxies, powers of attorney, instructions or other requests with respect to such Founder’s Founder Shares. Each Founder shall take such further action or execute such other instruments as may be necessary to effectuate the intent of this proxy.

(c) Each Founder affirms that the irrevocable proxy set forth in this Section 2.4 is given in connection with the execution of the Share Purchase Agreement, and that such irrevocable proxy is given to secure the performance of the duties of such Founder under this

Agreement. Each Founder further affirms that the irrevocable proxy is coupled with an interest and, except as set forth in this Section 2.4, is intended to be irrevocable; provided, that such proxy shall be automatically terminated in respect of the matters described in Section 2.1 at the Expiration Time.

The parties hereto agree that the foregoing is a voting agreement.

Section 2.5. Restrictions on Transfers. Each Founder hereby agrees that, from the date hereof until the Expiration Time, such Founder shall not, and shall cause its Affiliates not to, directly or indirectly, (a) Transfer any Founder Shares if such Transfer (x) has, or would reasonably be expected to have, the effect of reducing or limiting such Founder’s economic interest in such Founder Shares or (y) grants a third party the right to vote or direct the voting of such Founder Shares, (b) deposit any Founder Shares into a voting trust or enter into a voting agreement or arrangement or grant any proxy or power of attorney with respect thereto that is inconsistent with this Agreement, (c) convert or exchange, or take any action which would result in the conversion or exchange of, any Founder Shares, (d) knowingly take any action that would make any representation or warranty of such Founder set forth in this Agreement untrue or incorrect or have the effect of preventing, disabling, or delaying such Founder from performing any of its obligations under this Agreement, or (e) agree (whether or not in writing) to take any of the actions referred to in the foregoing clauses (a), (b), (c) or (d).

ARTICLE III

RIGHT OF FIRST REFUSAL

Section 3.1. Transfer Notice. Subject to Section 3.3, if at any time upon and after the Closing (a) any of the Founders (the “Selling Shareholder”) proposes to Transfer any Securities of the Company held by such Selling Shareholder, in whole or in part, to one or more Third Parties; or (b) any Securities held directly or indirectly by the Selling Shareholder are Transferred involuntarily pursuant to divorce, legal separation, bankruptcy or other proceedings, death or any other involuntary Transfer (collectively, “Involuntary Transfers”), then such Selling Shareholder (or its, his or her executor) shall first comply with the provisions of Section 3.2. Notwithstanding the foregoing, a Transfer resulting from the death of a Founder shall not be deemed to be an Involuntary Transfer if the transferee, upon request of any party hereto or receiving a Purchase Notice, executes the written agreement contemplated in the proviso at the end of Section 3.3, in which case such transferee shall be deemed to be a Permitted Transferee.

Section 3.2. Right of First Refusal.

(a) Prior to making or accepting an offer to Transfer any of its Securities to any third party, a Selling Shareholder (or its, his or her executor) shall give the Investor a written notice of its intention to make such Transfer (the “Transfer Notice”), which shall include (i) a description (including the class and the total number) of Securities to be Transferred (the “Offered Shares”); (ii) the identity of the prospective transferee(s); and (iii) the proposed offer price per Offered Shares (the “Offer Price”) and the material terms and conditions upon which the proposed Transfer is to be made. The Transfer Notice shall certify that the Transferor has received a firm offer from the prospective bona fide transferee(s) or otherwise believes in good faith that a

binding agreement for the Transfer is obtainable on the terms set forth in the Transfer Notice. The Transfer Notice shall also include a copy of any written proposal, term sheet or letter of intent or other agreement relating to the proposed Transfer. The Selling Shareholder and the Investor shall thereafter comply with the following provisions of Section 3.2.

(b) The Investor shall be granted the right of first refusal by the terms of the Transfer Notice, which the Investor can exercise upon giving written notice to the Selling Shareholder (the “Purchase Notice”) within thirty (30) days after its receipt of the Transfer Notice. The Purchase Notice shall specify the maximum number of Offered Shares which the Investor desires to purchase. The Investor will have the right to purchase all of the Offered Shares, on the same terms and conditions as set forth in the Transfer Notice, subject to Section 3.2(d) and (e).

(c) In the event that the Transfer in question is an Involuntary Transfer, the price per share shall be the greater of the original purchase price paid by the Selling Shareholder for such Offered Shares (appropriately adjusted for share splits, share dividends, combinations and the like) and the fair market value of such Offered Shares, which, if the Common Stock is at the relevant time listed on an established U.S. national or non-U.S. securities exchange or reported through or an established over-the-counter trading system, shall be determined with reference to the price per share of Common Stock based on the trailing average VWAP over the preceding ten (10) consecutive Trading Days prior to the effective date of the Involuntary Transfer.

(d) In the event the consideration for the Offered Shares specified in a Transfer Notice is payable in property other than cash and the Selling Shareholder and the Investor cannot agree on the cash value of such property within ten (10) days after the Investor’s receipt of the Transfer Notice, the value of such property shall be determined by an appraiser of recognized standing selected jointly by the Selling Shareholder on one hand and the Investor on the other hand. If they cannot agree on an appraiser within twenty (20) days after receipt of the Transfer Notice by the Investor, within a further five (5)-day period, the Selling Shareholder on one hand and the Investor on the other hand shall each select an appraiser of recognized standing and the two appraisers shall designate a third appraiser of recognized standing to determine the value of such property. The value of such property shall be determined by the appraiser selected pursuant to this Section within one month from its appointment, and such determination shall be final and binding on the Selling Shareholder and the Investor. The cost of such appraisal shall be shared equally by the Selling Shareholder on one hand and the Investor on the other hand. If the thirty (30) day period as specified in Section 3.2(b) has expired but for the determination of the value of the consideration for the Offered Shares offered by the Selling Shareholder, then such thirty (30) day period shall be extended to the fifth (5th) Business Day after such valuation shall have been determined to be final and binding pursuant to this Section.

(e) Notwithstanding anything to the contrary in this Section 3.2, in the event that a Investor elects to purchase any Offered Shares pursuant to its right of first refusal hereunder and the Common Stock is at the relevant time listed on an established U.S. national or non-U.S. securities exchange or reported through or an established over-the-counter trading system, the Offer Price payable by the Investor shall be the lower of (i) the Offer Price as set forth in the Transfer Notice, subject to Section 3.2(d), and (ii) the trailing average VWAP over the preceding ten (10) consecutive Trading Days immediately prior to the delivery of the Purchase Notice by the Investor to the Selling Shareholder in respect of such Offered Shares.

(f) To the extent that the Investor has not exercised their rights to purchase the Offered Shares subject to the Transfer Notice, the Selling Shareholder shall have a period of sixty (60) days from the expiration of such rights in which to sell any remaining Offered Shares, upon terms and conditions (including, without limitation, the purchase price) no more favorable to the purchaser than those specified in the Transfer Notice, to the third party transferee(s) identified in the Transfer Notice and the Offered Shares that are sold shall not be subject to the terms and provisions of this Agreement and all proxies granted hereunder shall terminate but solely with respect to the Offered Shares that have been sold. In the event a Selling Shareholder does not consummate the sale or disposition of the Offered Shares within the sixty (60) day period from the expiration of these rights, the Investor’ right of first refusal shall continue to be applicable to any subsequent disposition of any Common Stock by any Selling Shareholder. Furthermore, the exercise or non-exercise by the Investor to purchase Offered Shares by the Selling Shareholder shall not adversely affect the Investor’s rights to make subsequent purchases from any Selling Shareholder. Any proposed Transfer on terms and conditions significantly different than those described in the Transfer Notice, as well as any subsequent proposed Transfer of any of the Offered Shares by a Selling Shareholder shall again be subject to the right of first refusal of the Investor as provided under this Section 3.2 and shall require compliance by the relevant Selling Shareholder with the procedures described in this Agreement.

Section 3.3. Exempt Transfers. Subject to this Section 3.3, none of the restrictions and/or requirements contained in Section 3.1 and Section 3.2 with respect to Transfers of Securities shall apply to any:

(a) Transfer of the Securities, directly or indirectly, by the Founder to the Founder’s ancestors, descendants, immediate family members, or spouse or to trusts for the benefit of such persons or parties or to the entities in which the Founder and/or his ancestors, descendants, immediate family members, or spouse holds 100% of the equity or beneficial interests;

(b) Transfer of Securities by a Founder for estate planning purposes to a limited partnership, trust, association or other entity that is wholly-owned or controlled by such Founder;

(e) bona fide sale of Securities by a Founder or the Investor to a Third Party of less than 3% of the Securities held by such Founder or the Investor, as applicable, during any three month period;

provided, that each Permitted Transferee shall, as a condition to the effectiveness of any such Permitted Transfer, furnish the parties hereto with a written agreement to be bound by and comply with this Agreement, including, without limitation, all provisions of ARTICLE II and ARTICLE III, as if such transferee(s) were the transferor hereunder, as well as the terms of the agreement pursuant to which such Offered Shares were issued; provided, further, that the transferor shall remain liable for any breach by such Permitted Transferee of any provision hereunder.

ARTICLE IV

REPRESENTATIONS AND WARRANTIES

Section 4.1. Representations and Warranties of the Founders. Except as set forth on Schedule A, each of the Founders, on a several and not joint and several basis, represents and warrants to the Investor as follows:

(a) Ownership. Such Founder (i) is as of the date hereof the beneficial owner of, and has good and valid title to, its Owned Shares as set forth in Schedule A, and, immediately prior to the Closing, will be the beneficial owner of, and will have good and valid title to, its Securities, in each case free and clear of Liens other than as created by this Agreement, and (ii) has as of the date hereof with respect to all of its Owned Shares as set forth in Schedule A and will have immediately prior to the Closing with respect to all of its Founder Shares sole or shared (together with Affiliates controlled by such Founder) voting power, power of disposition, and power to demand dissenter’s rights, with no limitations, qualifications, or restrictions on such rights, subject to applicable United States federal securities Laws and the terms of this Agreement; (iii) except pursuant hereto, there are no options, warrants or other rights, agreements, arrangements or commitments of any character to which such Founder is a party relating to the pledge, disposition or voting of any of its Founder Shares and its Founder Shares are not subject to any voting trust agreement or other contract to which such Founder is a party restricting or otherwise relating to the voting or Transfer of such Founder Shares other than this Agreement; (iv) as of the date hereof and as of the Closing Date, other than its Owned Shares, such Founder does not own, beneficially or of record, or have the right to acquire, any shares of Common Stock or other securities of the Company, or any direct or indirect interest in any such securities (including by way of derivative securities); and (v) such Founder has not appointed or granted any proxy or power of attorney that is still in effect with respect to any of its Owned Shares, except as contemplated by this Agreement;

(b) Non-Contravention; No Conflicts. Except for the applicable requirements of the Securities Exchange Act of 1934, no filing or notice by the Founders with or to any Governmental Authority, and no authorization, consent, permit or approval from any Governmental Authority or any other Person is necessary for the execution and delivery of this Agreement or the performance obligations herein. The execution and delivery of this Agreement does not, and the performance of such Founder’s obligations under this Agreement and the consummation of the transactions contemplated by this Agreement, will not (1) conflict with, or result in any violation or breach of, or default (with or without notice or lapse of time, or both) under, or give rise to a right of, or result in, termination, cancellation or acceleration of any obligation or loss of any material benefit under, or to increased, additional, accelerated or guaranteed rights or entitlements of any Person under, or result in the creation of any Liens upon its assets or properties under, any provision of (A) any contract, agreement or other instrument to which any of the Founders is party or by which any of his assets or properties is bound, (B) any judgment, order, injunction, decree or Law applicable to the Founders or their assets or properties or (2) require any consent of, registration, declaration or filing with, notice to or permit from any Governmental Authority. For purposes of clarity it is acknowledged that a

Founder is not making any representation or warranty regarding any contract, agreement or other instrument to which the Company or any other person (other than such Founder) is a party or by which any of a person’s assets are bound or any judgement, order, injunction, decree or Law applicable to the Company or any other person (other than such Founder).

(c) No Action. As of the date of this Agreement, there are no proceedings, claims, actions, suits or governmental or regulatory investigations pending or, to the knowledge of the Founders threatened against the Founders that could reasonably be expected to impair the ability of the Founders to timely perform in all material respects their obligations hereunder or to consummate the transactions contemplated hereby on a timely basis.

Section 4.2. Representations and Warranties of the Investor. The Investor represents and warrants to the Founders as follows:

(a) Capacity; Authorization; Validity of Agreement; Necessary Action. The Investor is duly organized or formed, validly existing and in good standing under the Laws of the jurisdiction in which the Investor is organized or formed (in the case of good standing, to the extent the concept is recognized by such jurisdiction). The Investor has the legal capacity and authority (including corporate, limited partnership, trust or other organizational power, as applicable) to execute and deliver this Agreement and perform the Investor’s obligations hereunder and to consummate the transactions contemplated by this Agreement. This Agreement has been duly executed and delivered by the Investor and constitutes a legal, valid and binding agreement of the Investor enforceable against the Investor in accordance with its terms, subject to bankruptcy, insolvency, fraudulent transfer, reorganization, moratorium and similar Laws of general applicability relating to or affecting creditors’ rights and to general equity principles.

(b) Non-Contravention; No Conflicts. Except for the applicable requirements of the Securities Exchange Act of 1934, no filing or notice by the Investor with or to any Governmental Authority, and no authorization, consent, permit or approval from any Governmental Authority or any other Person is necessary for the execution and delivery of this Agreement by the Investor or the performance by the Investor of the Investor’s obligations herein. The execution and delivery of this Agreement by the Investor does not, and the performance by the Investor of its obligations under this Agreement and the consummation by the Investor of the transactions contemplated by this Agreement, will not (1) conflict with, or result in any violation or breach of, or default (with or without notice or lapse of time, or both) under, or give rise to a right of, or result in, termination, cancellation or acceleration of any obligation or loss of any material benefit under, or to increased, additional, accelerated or guaranteed rights or entitlements of any Person under, or result in the creation of any Liens upon its assets or properties under, any provision of (A) any contract, agreement or other instrument to which the Investor is party or by which any of its assets or properties is bound, (B) any charter or organizational documents of the Investor or (C) any judgment, order, injunction, decree or Law applicable to the Investor or its assets or properties or (2) require any consent of, registration, declaration or filing with, notice to or permit from any Governmental Authority.

(c) No Action. As of the date of this Agreement, there are no proceedings, claims, actions, suits or governmental or regulatory investigations pending or, to the knowledge of the Investor, threatened against the Investor that could reasonably be expected to impair the ability of the Investor to timely perform in all material respects its obligations hereunder or to consummate the transactions contemplated hereby on a timely basis.

(d) Ownership. As of the date hereof and as of the Closing, other than pursuant to the Share Purchase Agreement and the transactions contemplated thereunder, the Investor and its Affiliates do not own, beneficially or of record, or have the right to acquire, any shares of Common Stock or other Securities of the Company, or any direct or indirect interest in any such Securities (including by way of derivative securities).

A party may change or supplement the addresses given above, or designate additional addresses, for purposes of this Section 5.3 by giving the other party written notice of the new address in the manner set forth above.

Section 5.4. Governing Law. This Agreement shall be governed by, and construed in accordance with, the Laws of the State of New York, without regard to principles of conflict of Laws thereunder other than New York General Obligations Law Section 5-1401.

Section 5.5. Dispute Resolution.

(a) Any and all disputes which cannot be settled amicably, including any ancillary claims of any party, arising out of, relating to or in connection with the validity, negotiation,

execution, interpretation, performance or non-performance of this Agreement (including the validity, scope and enforceability of this arbitration provision) shall be referred to and finally resolved by arbitration under the Rules of Arbitration of the London Court of International Arbitration (“LCIA Rules”) by one or more arbitrators appointed in accordance with the LCIA Rules (the “Arbitral Tribunal”);

(b) The arbitration shall be conducted by a sole arbitrator unless either party objects, in which case the arbitration shall be conducted by a panel of three arbitrators. Where the arbitration is to be conducted by a sole arbitrator, the parties shall attempt to agree upon the selection of the sole arbitrator. If they cannot reach agreement within 30 days from the commencement of the arbitration, the sole arbitrator shall be appointed by the Court of the LCIA (the “LCIA Court”) in accordance with the LCIA Rules. Where the arbitration is to be conducted by a panel of three arbitrators, each party shall nominate one arbitrator and the two party-nominated arbitrators shall then select the chairman of the Arbitral Tribunal. If the two party-nominated arbitrators are unable to do so within 30 days after the commencement of the arbitration or any mutually agreed extension thereof, the chairman shall be selected by the LCIA Court in accordance with the LCIA Rules;

(d) The language of the arbitration shall be English;

(e) Each arbitrator shall be licensed to practice law in New York;

(f) Each party shall have the right to apply to any court of competent jurisdiction and/or to the Arbitral Tribunal for an order or award of interim, provisional or conservatory measures in order to maintain the status quo or to protect its rights or property pending arbitration pursuant to this Agreement or for the purpose of compelling a party to arbitrate and seeking temporary or preliminary relief in aid of an arbitration hereunder, and any such application shall not be deemed incompatible with, or a waiver of, the parties’ agreement to arbitrate;

(g) The Arbitral Tribunal shall have power to take whatever interim measures it deems necessary, including injunctive relief, specific performance and other equitable relief, including in accordance with the provisions set forth in Section 5.12 of this Agreement;

(h) The award rendered by the Arbitral Tribunal shall be final and binding between the parties and not subject to appeal or other recourse; and

(i) Recognition and enforcement of any award rendered by the Arbitral Tribunal may be sought in any court of competent jurisdiction.

Section 5.6. Severability. If any provision of this Agreement is found to be invalid or unenforceable, then such provision shall be construed, to the extent feasible, so as to render the provision enforceable and to provide for the consummation of the transactions contemplated hereby on substantially the same terms as originally set forth herein, and if no feasible interpretation would save such provision, it shall be severed from the remainder of this Agreement, which shall remain in full force and effect unless the severed provision is essential to

the rights or benefits intended by the parties. In such event, the parties shall use commercially reasonable efforts to negotiate, in good faith, a substitute, valid and enforceable provision or agreement, which most nearly effects the parties’ intent in entering into this Agreement.

Section 5.7. No Third Party Beneficiaries. This Agreement shall be binding upon and inure solely to the benefit of, and be enforceable by, only the parties hereto and their respective successors and permitted assigns and nothing herein, express or implied, is intended to or shall confer upon any other Person any right, benefit or remedy of any nature whatsoever, under or by reason of this Agreement.

Section 5.8. Successors and Assigns. The provisions of this Agreement shall inure to the benefit of, and shall be binding upon, the successors and permitted assigns of the parties hereto. Except as otherwise provided herein, neither this Agreement nor any of the rights, interests, or obligations hereunder shall be assigned by any party hereto (whether by operation of Law or otherwise) without the prior written consent of the Investor, on the one hand, and the Founders, on the other hand.

Section 5.9. Construction. Each of the parties has participated in the drafting and negotiation of this Agreement. If an ambiguity or question of intent or interpretation arises, this Agreement must be construed as if it is drafted by all the parties and no presumption or burden of proof shall arise favoring or disfavoring any party by virtue of authorship of any of the provisions of this Agreement.

Section 5.10. Counterparts. This Agreement may be executed in one or more counterparts, each of which shall be deemed to constitute an original, but all of which together shall constitute one and the same document. Signatures to this Agreement transmitted by facsimile transmission, by electronic mail in “portable document format” (“.pdf”) form, or by any other electronic means intended to preserve the original graphic and pictorial appearance of a document will have the same effect as physical delivery of the paper document bearing the original signature.

Section 5.11. Calculation of Investor Shares. In calculating the Investor’s ownership of Common Stock at any given time and from time to time for purposes of determining the availability of any Investor rights under this Agreement, all Securities held or acquired by the Investor and/or its Affiliates shall be aggregated together and any Securities other than Common Stock which are ultimately convertible or exercisable into, or exchangeable for, Common Stock rights will be deemed to have been convertible or exercisable into Common Stock (regardless of whether at such time conversion or exercise is permissible under the terms of such Security).

Section 5.12. Specific Performance. Except as otherwise expressly provided herein, any and all remedies provided herein will be deemed cumulative with and not exclusive of any other remedy conferred hereby, or by law or equity upon such party, and the exercise by a party of any one remedy will not preclude the exercise of any other remedy. The parties hereto agree that irreparable damage would occur in the event that any of the provisions of this Agreement were not performed by the parties hereto in accordance with their specific terms or were otherwise breached. It is accordingly agreed that the Investor, on the one hand, and each of the Founders, on the other hand, shall be entitled to seek an injunction or injunctions, specific performance and

other equitable remedies to prevent breaches of this Agreement by the other (as applicable) and to seek to enforce specifically the terms and provisions of this Agreement and to thereafter cause the transactions contemplated by this Agreement to be consummated on the terms and subject to the conditions thereto set forth in this Agreement. The foregoing rights are in addition to and without limitation of any other remedy to which the parties may be entitled at law or in equity. The parties further agree not to assert that a remedy of specific performance is unenforceable, invalid, contrary to law or inequitable for any reason, nor to assert that a remedy of monetary damages would provide an adequate remedy. Each of the parties hereto hereby waives (i) any defenses in any action for specific performance, including the defense that a remedy at law would be adequate and (ii) any requirement under any Law to post a bond or other security as a prerequisite to obtaining equitable relief.

Section 5.13. Amendment; Waiver. Any provision of this Agreement may be amended, modified or supplemented only by a written instrument duly executed by all the parties hereto. The observance of any provision in this Agreement may be waived (either generally or in a particular instance and either retroactively or prospectively), only by the written consent of the party against whom such waiver is to be effective. Any amendment or waiver effected in accordance with this Section 5.13 shall be binding upon the Investor, the Founders and their respective assigns. It is agreed that no delay or omission to exercise any right, power or remedy accruing to any party, upon any breach, default or noncompliance by another party under this Agreement, shall impair any such right, power or remedy, nor shall it be construed to be a waiver of any such breach, default or noncompliance, or any acquiescence therein, or of or in any similar breach, default or noncompliance thereafter occurring.

Section 5.14. Expenses. Except as expressly provided herein, each party will bear its own costs and expenses incurred by it or on its behalf in connection with the Transaction Documents and the transactions contemplated thereby.

Section 5.15. Additional Securities. Each of the Founders and Investor covenants and agrees to promptly (and in any event within 48 hours) notify the other parties of any new Securities of the Company with respect to which beneficial ownership is acquired by such party or their respective Affiliates, including, without limitation, by purchase, as a result of a share dividend, share split, recapitalization, combination, reclassification, exchange or change of such shares, or upon exercise or conversion of any securities of the Company, if any, after the date hereof. Any such Securities shall automatically become subject to the terms of this Agreement and Schedule A hereto shall be deemed amended accordingly.

Section 5.16. Disclosure. Unless required by Law, any stock exchange rules, or upon request of any Governmental Authority or stock exchange, each of the Parties shall not, and shall cause their respective Affiliates not to, make any press release, public announcement or other public communication that criticizes or disparages this Agreement or the Share Purchase Agreement or the transactions contemplated hereby or thereby, without the prior written consent of the other parties. Each party (a) consents to and authorizes the publication and disclosure by any party of the other parties’ identity and ownership of the Securities and the existence and terms of this Agreement (including, for the avoidance of doubt, the disclosure of this Agreement) and any other information, in each case, that a party reasonably determines in its good faith judgment is required to be disclosed by Law or any stock exchange rules in any press release,

any other disclosure document in connection with the Share Purchase Agreement or this Agreement and any filings with or notices to any Governmental Authority or stock exchange in connection with the Share Purchase Agreement or this Agreement (or the transactions contemplated thereby or hereby) and (b) agrees promptly to give to any party any information they may reasonably request for the preparation of any such documents.
