Section 7.4 Specific Performance. Each party acknowledges and agrees that monetary damages would not be an adequate remedy in the event that any covenant or agreement in this Agreement is not performed in accordance with its terms, and therefore agrees that in the event of any breach by a party hereto of any of its, his or her respective covenants or agreements set forth in this Agreement, the non-breaching parties shall each be entitled to specific performance of the terms hereof, including an injunction or injunctions to prevent breaches of this Agreement by any party, in addition to any other remedy at law or equity. Each party waives (i) any defenses in any action for an injunction or other appropriate form of specific performance or equitable relief, 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 an injunction or other appropriate form of specific performance or equitable relief. All rights, powers, and remedies provided under this Agreement or otherwise available in respect hereof at law or in equity shall be cumulative and not alternative, and the exercise or beginning of the exercise of any thereof by a party shall not preclude the simultaneous or later exercise of any other such right, power or remedy by a party.

Section 7.5 Amendments; Waivers. At any time prior to the Expiration Time, any provision of this Agreement may be amended or waived if, and only if, such amendment or waiver is in writing and signed, in the case of an amendment, by the parties hereto, or in the case of a waiver, by the party against whom the waiver is to be effective. Notwithstanding the foregoing, no failure or delay by a party hereto in exercising any right hereunder shall operate as a waiver thereof nor shall any single or partial exercise thereof preclude any other or further exercise of any other right hereunder.

Section 7.6 Governing Law. This Agreement shall be governed by, and construed in accordance with, the Laws of the State of New York, without giving effect to any choice of Law or conflict of Law rules or provisions that would cause the application of the Laws of any jurisdiction other than the State of New York.

Section 7.7 Dispute Resolution.

(a) Any disputes, actions and proceedings against any party or arising out of or in any way relating to this Agreement shall be submitted to the Hong Kong International Arbitration Centre (“HKIAC”) and resolved in accordance with the arbitration rules of HKIAC in force at the relevant time and as may be amended by this Section 7.7 (the “Rules”). The place of arbitration shall be Hong Kong. The official language of the arbitration shall be English and the arbitration tribunal shall consist of three arbitrators (each, an “Arbitrator”). The claimant(s), irrespective of number, shall nominate jointly one Arbitrator; the respondent(s), irrespective of number, shall nominate jointly one Arbitrator; and a third Arbitrator will be nominated jointly by the first two Arbitrators and shall serve as chairman of the arbitration tribunal. In the event the claimant(s) or respondent(s) or the first two Arbitrators shall fail to nominate or agree the joint nomination of an Arbitrator or the third Arbitrator within the time limits specified by the Rules, such Arbitrator shall be appointed promptly by the HKIAC. The arbitration tribunal shall have no authority to award punitive or other punitive-type damages. The award of the arbitration tribunal shall be final and binding upon the disputing parties. Any party to an award may apply to any court of competent jurisdiction for enforcement of such award and, for purposes of the enforcement of such award, the parties irrevocably and unconditionally submit to the jurisdiction of any court of competent jurisdiction and waive any defenses to such enforcement based on lack of personal jurisdiction or inconvenient forum.

(b) Notwithstanding the foregoing, the parties hereby consent to and agree that in addition to any recourse to arbitration as set out in this Section 7.7, any party may, to the extent permitted under the Laws of the jurisdiction where application is made, seek an interim injunction from a court or other authority with competent jurisdiction and, notwithstanding that this Agreement is governed by the Laws of the State of New York, a court or authority hearing an application for injunctive relief may apply the procedural Law of the jurisdiction where the court or other authority is located in determining whether to grant the interim injunction. For the avoidance of doubt, this Section 7.7(b) is only applicable to the seeking of interim injunctions and does not restrict the application of Section 7.7(a) in any way.

Section 7.8 No Third Party Beneficiaries. There are no third party beneficiaries of this Agreement and nothing in this Agreement, express or implied, is intended to confer on any person other than the parties hereto (and their respective successors, heirs and permitted assigns), any rights, remedies, obligations or liabilities, except as specifically set forth in this Agreement; provided, that the Company is an express third-party beneficiary of the obligations of the Rollover Shareholder pursuant to Section 2.2 and Article III of this Agreement and shall be entitled to specific performance of the terms thereof, including an injunction or injunctions to prevent breaches of this Agreement by the parties thereto, in addition to any other remedy at law or equity.

Section 7.9 Assignment; Binding Effect. Neither this Agreement nor any of the rights, interests or obligations hereunder shall be assigned by any of the parties hereto (whether by operation of Law or otherwise) without the prior written consent of the other parties. Subject to the preceding sentence, this Agreement shall be binding upon and shall inure to the benefit of the parties hereto and their respective successors and permitted assigns.

Section 7.10 No Presumption Against Drafting Party. Each of the parties to this Agreement acknowledges that it has been represented by independent counsel in connection with this Agreement and the transactions contemplated by this Agreement. Accordingly, any rule of Law or any legal decision that would require interpretation of any claimed ambiguities in this Agreement against the drafting party has no application and is expressly waived.

Section 7.11 Further Assurances. The Rollover Shareholder hereby covenants that, from time to time, it will do, execute, acknowledge and deliver, or cause to be done, executed, acknowledged and delivered, such further acts, conveyances, transfers, assignments, powers of attorney and assurances necessary to convey, transfer to and vest in Merger Sub, and to put Merger Sub in possession of, all of the Rollover Shares in accordance with the terms of this Agreement.

Section 7.12 Counterparts. This Agreement may be executed in two or more consecutive counterparts (including by facsimile or email pdf format), each of which shall be an original, with the same effect as if the signatures thereto and hereto were upon the same instrument, and shall become effective when one or more counterparts have been signed by each of the parties and delivered (by telecopy, email pdf format or otherwise) to the other parties.

Section 7.13 Confidentiality. This Agreement shall be treated as confidential and may not be used, circulated, quoted or otherwise referred to in any document, except with the prior written consent of the parties hereto; provided, that each party hereto may, without such written consent, disclose the existence and content of this Agreement to its officers, directors, employees, partners, members, investors, financing sources, advisors (including financial and legal advisors) and any representatives of the foregoing and to the extent required by Law, the applicable rules of any national securities exchange or in connection with any SEC filings relating to the transactions contemplated hereby or by the Merger Agreement.

Section 7.14 Interpretation. When a reference is made in this Agreement to a Section or Article such reference shall be to a Section or Article of this Agreement unless otherwise indicated. The headings contained in this Agreement are for convenience of reference purposes only and shall not affect in any way the meaning or interpretation of this Agreement.
