Section 3.02 Issuance Notice    (a) In the event the Company proposes to undertake an issuance of Additional
Securities, it shall give each of the holders of the Ordinary Shares (except the Award Shares) and the Preferred Shares (a “Participation Right Holder”) a written notice (an “Issuance Notice”) of such intention,

Notice shall contain the material terms and conditions of the proposed transfer, including without limitation a description of the Shares (the “Transfer Shares”) that such Transferor proposes to transfer, and the identity of the

Transferor and the Company indicating the number of shares such Eligible Holder wishes to purchase within thirty (30) calendar days after delivery of the Proposed Transfer Notice (“ROFR Exercise Period”).

Holder”) shall have the right to participate (on a pro-rata basis as among the Co-sale Eligible Holders and the Selling Shareholder) in the sale of such Offered Shares at the same price and subject to the same terms and conditions proposed
by a bona fide prospective purchaser. If the prospective purchaser refuses to purchase Equity Securities subject to the Right of Co-Sale from the Co-Sale Eligible Holders, no Selling Shareholder may sell any Offered Shares to such prospective
purchaser unless and until, simultaneously with such sale, such prospective purchaser purchases all Equity Securities subject to the Right of Co-Sale from the Co-Sale Eligible Holders. 

(c) To exercise its Right of Co-Sale, a Co-Sale Eligible Holder must give the Selling Shareholder a written notice to that effect within

 Section 7.08 Amendments and Waivers 

Any term of this Agreement may be amended, terminated or waived only with the written consent of the Parties. Any amendment or waiver effected
in accordance with this Section 7.08 shall be binding upon the Parties, and each transferee, successor and/or assignee of the Parties. 

Section 7.09 Severability 

The invalidity or unenforceability of any provision hereof shall in no way affect the validity or enforceability of any other provision. 

Section 7.10 Delays or Omissions 

No delay or omission to exercise any right, power or remedy accruing to any party under this Agreement, upon any breach or default of any other
party under this Agreement, shall impair any such right, power or remedy of such non-breaching or non-defaulting party nor shall it be construed to be a waiver of any such breach or default, or an acquiescence therein, or of or in any similar breach
or default thereafter occurring; nor shall any waiver of any single breach or default be deemed a waiver of any other breach or default theretofore or thereafter occurring. Any waiver, permit, consent or approval of any kind or character on the part
of any party of any breach or default under this Agreement, or any waiver on the part of any party of any provisions or conditions of this Agreement, must be in writing and shall be effective only to the extent specifically set forth in such
writing. All remedies, either under this Agreement or by law or otherwise afforded to any party, shall be cumulative and not alternative. 

Section 7.11 Entire Agreement 

This Agreement (including the schedules and exhibits hereto) and any other agreements, instruments or documents entered into in connection with
this Agreement constitute the full and entire understanding and agreement between the Parties with respect to the subject matter hereof, and any other written or oral agreement relating to the subject matter hereof existing between the Parties are
expressly cancelled. 
 Section 7.12 Dispute Resolution 

(a) Any dispute, controversy or claim arising out of or relating to this Agreement, or the interpretation, breach, termination or validity
hereof, shall first be subject to resolution through consultation of the Parties to such dispute, controversy or claim. Such consultation shall begin within seven (7) days after one Party hereto has delivered to the other Parties involved a
written request for such consultation. If within thirty (30) days following the commencement of such consultation the dispute cannot be resolved, the dispute shall be submitted to arbitration upon the request of any Party with notice to the
other Parties. 
 (b) The arbitration shall be conducted in Hong Kong under the auspices of the Hong Kong International Arbitration Centre
(the “HKIAC”). There shall be three (3) arbitrators. The complainant and the respondent to such dispute shall each select one arbitrator within thirty (30) days after giving or receiving the demand for arbitration. Such
arbitrators shall be freely selected, and the Parties shall not be limited in their selection to any prescribed list. The Chairman of the HKIAC shall select the third arbitrator, who shall be qualified to practice Law in Hong Kong. If either Party
to the arbitration does not appoint an arbitrator who has consented to participate within thirty (30) days after selection of the first arbitrator, the relevant appointment shall be made by the Chairman of the HKIAC. 

  
 24 








 (c) The arbitration proceedings shall be conducted in English. The arbitration tribunal shall
apply the Arbitration Rules of the HKIAC in effect at the time of the arbitration. However, if such rules are in conflict with the provisions of this Section 7.12, including the provisions concerning the appointment of arbitrators, the
provisions of this Section 7.12 shall prevail. 
 (d) The arbitrators shall decide any dispute submitted by the Parties to the
arbitration strictly in accordance with the substantive law of Hong Kong and shall not apply any other substantive law. 
 (e) Each Party
hereto shall cooperate with any party to the dispute in making full disclosure of and providing complete access to all information and documents requested by such Party in connection with such arbitration proceedings, subject only to any
confidentiality obligations binding on the Party receiving the request. 
 (f) The award of the arbitration tribunal shall be final and
binding upon the disputing parties, and any Party to the dispute may apply to a court of competent jurisdiction for enforcement of such award. 

(g) Any Party to the dispute shall be entitled to seek preliminary injunctive relief, if possible, from any court of competent jurisdiction
pending the constitution of the arbitral tribunal. 
 Section 7.13 Cumulative Rights    Each and all of the
various rights, powers and remedies of a Party will be considered to be cumulative with and in addition to any other rights, powers and remedies which such Party may have at law or in equity in the event of the breach of any of the terms of this
Agreement. The exercise or partial exercise of any right, power or remedy will neither constitute the exclusive election thereof nor the waiver of any other right, power or remedy available to such Party. 

Section 7.14 Further Assurance 

Each of the Parties hereto undertakes with each of the other Parties that it shall do, or shall procure to be done, all such acts and things
and shall execute, or shall procure to be executed, all such documents as may be necessary or appropriate to implement the provisions of this Agreement or otherwise to give full legal force and effect thereof. 

Section 7.15 Remedies. 

The Parties hereto, in addition to being entitled to exercise all rights granted by law, including recovery of damages, will be entitled to
specific performance of their rights under this Agreement. Each of the Parties agrees that monetary damages would not be adequate compensation for any loss incurred by reason of a breach by it of the provisions of this Agreement and hereby agrees to
waive the defense in any action for specific performance that a remedy at law would be adequate. In addition, the rights of the Parties set forth in this Agreement shall be in addition to, and not in lieu of, any other rights that the Parties may
have in any capacity or otherwise. 
 Section 7.16 Conflict with the Restated Memorandum and Articles. 

In the event of any conflict or inconsistency between the provisions of this Agreement and the provisions of the Restated Memorandum and
Articles or other constitutional documents of the Company, the terms of this Agreement shall prevail as between the shareholders of the Company only. The Parties shall, notwithstanding the conflict or inconsistency, act so as to effect the intent of
this Agreement to the greatest extent possible under the circumstances and shall promptly amend the conflicting constitutional documents to conform to this Agreement to the greatest extent possible.
