without the prior written consent of the other parties, and the parties shall cooperate as to the timing and contents of any such press release or public announcement. 

Section 5.3 Cumulative Remedies. The rights and remedies provided by this Agreement are cumulative and the use of any one right or

Section 5.4 Binding Effect. This Agreement shall be binding upon and inure to the benefit of all of the parties and, to the extent
permitted by this Agreement, their successors, executors, administrators, heirs, legal representatives and assigns. 
 Section 5.5
Severability. If any term or other provision of this Agreement is invalid, illegal or incapable of being enforced by any Law or public policy, all other terms and provisions of this Agreement shall nevertheless remain in full force and effect
for so long as the economic or legal substance of the transactions contemplated by this Agreement is not affected in any manner materially adverse to any party hereto. Upon such determination that any term or other provision is invalid, illegal or
incapable of being enforced, the parties hereto shall negotiate in good faith to modify this Agreement so as to effect the original intent of the parties hereto as closely as possible in a mutually acceptable manner in order that the transactions
contemplated by this Agreement are effected as originally contemplated to the greatest extent possible. 
 Section 5.6 Entire
Agreement. This Agreement, together with the SHA, constitutes the entire agreement of the parties hereto with respect to the subject matter hereof as of the date hereof and supersedes all prior agreements and undertakings, both written and oral,
among the parties hereto with respect to the subject matter hereof. 
 Section 5.7 Governing Law. This Agreement shall be
governed by and construed in accordance with the laws of Hong Kong, without regard to the conflicts of laws rules stated therein. 

Section 5.8 Dispute Resolution. Any dispute, controversy or claim arising out of or relating to this Agreement, including, but not

“ICC”) in force at the time of commencement of the arbitration.

 (a) The arbitral tribunal shall consist of three arbitrators. The arbitrators shall be appointed
in accordance with the ICC Rules. 
 (b) The language to be used in the arbitration proceedings shall be English. 

(c) Any arbitration award shall be (i) in writing and shall contain the reasons for the decision, (ii) final and binding on the
parties hereto and (iii) enforceable in any court of competent jurisdiction, and the parties hereto agree to be bound thereby and to act accordingly. 

(d) The parties hereto expressly consent to the consolidation of arbitration proceedings commenced hereunder with arbitration proceedings
commenced pursuant to the arbitration agreements contained in the SHA. In addition, the parties hereto expressly agree that any disputes arising out of or in connection with this Agreement and the SHA concern the same transaction or series of

 (e) In the event a dispute is referred to arbitration hereunder, the parties hereto shall continue to exercise their
remaining respective rights and fulfill their remaining respective obligations under this Agreement.

with this arbitration agreement for any party to seek interim or conservatory relief from courts of competent jurisdiction before the constitution of the arbitral tribunal. 

Section 5.9 Specific Performance. The parties hereto acknowledge and agree that the parties hereto would be irreparably damaged if
any of the provisions of this Agreement are not performed in accordance with their specific terms or are otherwise breached and that any non-performance or breach of this Agreement by any party hereto could
not be adequately compensated by monetary damages alone and that the parties hereto would not have any adequate remedy at law. Accordingly, in addition to any other right or remedy to which any party hereto may be entitled, at law or in equity
(including monetary damages), such party shall be entitled to enforce any provision of this Agreement by a decree of specific performance and to temporary, preliminary and permanent injunctive relief to prevent breaches or threatened breaches of any
of the provisions of this Agreement without posting any bond or other undertaking.

provision, covenant or restriction of this Agreement is held by a court of competent jurisdiction to be invalid, void or unenforceable, the remainder of the terms, provisions, covenants and restrictions of this Agreement shall remain in full force
and effect and shall in no way be affected, impaired or invalidated so long as the economic or legal substance of the transactions contemplated hereby is not affected in any manner materially adverse to any party. Upon such a determination,
Investor, on the one hand, and Parent, on the other hand, shall negotiate in good faith to modify this Agreement so as to effect the original intent of the parties as closely as possible in an acceptable manner in order that the transactions
contemplated hereby be consummated as originally contemplated to the fullest extent possible. 
 Section 5.11 Expenses. All
costs and expenses, including fees and disbursements of counsel, financial advisors and accountants, incurred in connection with this Agreement and the transactions contemplated hereby shall be paid by the party incurring such costs and expenses.

 Section 5.12 Amendments and Waivers. 

(a) 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 or parties against whom the waiver is to be effective. 

(b) Any party to this Agreement may in accordance with subclause (a) above, (i) extend the time for the performance of any of the
obligations or other acts of the other party; or (ii) waive compliance with any of the agreements of the other party or conditions to such obligations contained herein. Notwithstanding the foregoing, no failure or delay by any 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 future exercise of any other right hereunder. The failure of any party hereto to assert any of its rights
hereunder shall not constitute a waiver of any of such rights 
 Section 5.13 Assignment. 

(a) This Agreement shall not be assigned without the express written consent of the parties hereto (which consent may be granted or withheld
in the sole discretion of any party), except Investor may assign its rights under this Agreement to (i) a Permitted Transferee to which Investor transfers any Securities in accordance with the terms and conditions of the SHA or
(ii) pursuant to Section 5.13(b). 
 (b) Investor may, by written notice to Parent, assign this Agreement without the consent of
Parent to any transferee to whom Investor transfers Acquired Shares in one or a series of related transactions within a three-month period so long as (i) such transferee is a Qualified New Investor and (ii) following such transfer, such
Qualified New Investor holds and continues to hold at least 50% of the Acquired Shares. From and after an assignment of this Agreement by Investor to a Qualified New Investor pursuant to this Section 5.13(b), except as otherwise agreed by the
Company, each Investor Director nominated or appointed by such Qualified New Investor (x) shall have experience or expertise in one or more of the following areas: Internet, social networking or microblogging, technology, finance or accounting
and (y) shall not be a shareholder, director, officer, employee or Affiliate of a Competitor or a Subsidiary of a Competitor, or of any operating company whose principal business activities are primarily in the Internet industry;
provided that any such Investor Director may beneficially own no more than 5% in a Competitor or a Subsidiary of Competitor that is publicly listed on an internationally recognized securities exchange, or of any operating company whose
principal business activities are primarily in the Internet industry and, for the avoidance of doubt, any ownership interests held by such Investor Director through a mutual fund or similar investment fund in which such Investor Director does not
direct investment decisions shall not be deemed to be beneficially owned by such Investor Director. Parent hereby agrees that, upon an assignment of this Agreement by the Investor pursuant to this Section 5.13(b), references to
“Investor” under this Agreement shall be deemed to be replaced by references to such Qualified New Investor to the extent applicable.

 Section 5.14 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, including any rights of employment for any specified period, under or by reason of this Agreement. 

Section 5.15 Construction. Each party hereto acknowledges and agrees it has had the opportunity to draft, review and edit the
language of this Agreement and that no presumption for or against any party arising out of drafting all or any part of this Agreement will be applied in any controversy, claim or dispute relating to, in connection with or involving this Agreement.
Accordingly, the parties hereto hereby waive the benefit of any rule of Law or any legal decision that would require, in cases of uncertainty, that the language of a contract should be interpreted most strongly against the party who drafted such
language. 
 Section 5.16 Counterparts;. This Agreement may be executed and delivered (including by facsimile or other means of
electronic transmission, such as by electronic mail in “pdf” form) in one or more counterparts, and by the different parties hereto in separate counterparts, each of which when executed shall be deemed to be an original, but all of which
taken together shall constitute one and the same agreement.
