The addresses and emails provided by the Parties shall be deemed as the delivery addresses for the resolution of disputes hereunder. The delivery addresses so confirmed shall be applicable to all stages of dispute resolution including arbitration, first instance, second instance, retrial and enforcement etc.

7.2 Governing Law

The execution, validity, interpretation, implementation of this Agreement and settlement of disputes in respect of this Agreement shall be governed by and construed in accordance with the laws of the PRC.

7.3 Dispute Resolution

In the event any dispute arises from the interpretation or implementation of this Agreement and any matter relating hereto, the Parties shall first endeavor to resolve such dispute through amicable negotiation. If no settlement can be reached through negotiation within thirty (30) days after one Party hereto has delivered to the other Parties involved a written request for such negotiation, any Party may submit such dispute to the China International Economic and Trade Arbitration Commission (CIETAC) for arbitration in Hangzhou under its then effective rules. The award of the arbitration tribunal shall be final and binding upon the Parties and shall not be subject to appeal. The arbitration fees shall be borne by the losing Party, unless otherwise determined by the arbitration award. When any dispute occurs and at the time of arbitration of any dispute, except for the matters under dispute, the Parties shall continue to exercise other rights and perform other obligations under this Agreement respectively.

7.4 Confidentiality

None of the Parties shall, or shall cause its affiliates, shareholders, directors, senior officers, employees, representatives or agents not to, directly or indirectly disclose the existence of this Agreement or any information related to the Equity Transfer and the Capital Increase (including any information obtained by such Party as a result of its participation in the negotiation and execution of this Agreement), except that (a) the prior written consent of the non-disclosing Party has been obtained, or (b) such information is required to be disclosed pursuant to applicable laws, and then only to the extent necessary to comply with such applicable laws or any rules or policies of any stock exchange, provided that the disclosing Party shall, within a reasonable time prior to the disclosure or submission of relevant information, seek opinions on such disclosure or submission from the other Party and, if required by the other Party, seek confidential treatment for the information disclosed or submitted to the extent possible.

- 28 -

7.5 Severability

The obligations hereunder shall be deemed as separate obligations and can be enforced separately. If certain obligation or obligations under this Agreement become unenforceable, the enforceability of the other obligations shall not be affected. The unenforceability of this Agreement against any Party shall not affect the enforceability of this Agreement between the other Parties. If any one or more provisions of this Agreement are determined to be invalid, illegal or unenforceable in any respect in accordance with any applicable laws, or are required to be modified by any governmental authority, the validity, legality and enforceability of the remaining provisions shall not be affected or compromised in any respect. The Parties shall negotiate in good faith and endeavor to replace such invalid, illegal or unenforceable provisions with valid provisions, the economic effect of which comes as close as possible to that of such invalid, illegal or unenforceable provisions.

7.6 Integrity

This Agreement (including other Series C Transaction Documents and any other documents referred to herein or contemplated thereby) shall constitute the entire agreement among the Parties with respect to the subject matter hereof and shall supersede any other prior agreements or intentions among the Parties with respect to the same subject matter. From the effective date of this Agreement to the completion of the next round of financing, there shall be no stipulations between the Parties to this Agreement and the Company and/or the Management Team with respect to shareholders’ special rights in any other form, otherwise such arrangement of shareholders’ special rights shall be deemed null and void. For the avoidance of doubt, each of the Series A Investment Agreement, Series B Investment Agreement and Series C Investment Agreement shall survive the parties thereto.

Subject to the PRC Laws and other provisions of this Agreement, the Investor shall have the right to transfer its rights and obligations hereunder to its Affiliates without the prior consent of the other Parties and the Company. The Investor shall have the right to transfer its rights and obligations hereunder, together with the sale or transfer of its equity interest (if any), to any third party, provided, however, that such transfer shall be subject to the Right of First Refusal of the other Investors as set forth in Article 3.2 hereof. Notwithstanding any other provisions of this Agreement, after the completion of its capital contribution obligation, the Investor shall transfer to its Affiliates the rights and obligations still enjoyed or assumed by it hereunder, together with the sale or transfer of its equity interest (if any), without being subject to any right of consent, Right of First Refusal, Right of Co-sale or similar rights of the other Shareholders. Except for the foregoing, no Party shall transfer its rights or obligations under this Agreement without the prior written consent of each of the other Parties; any transfer without such consent shall be deemed null and void.

This Agreement is written in the language of Chinese in forty-five (45) originals. Each Party shall hold one (1) original, and the remaining originals shall be filed by the Company. Each original shall have the same legal validity.

- 29 -

7.9 Precedence

If separate agreements (including but not limited to investment agreements, and the Articles of Association amended from time to time or amendments to the Articles of Association) are required to be executed in connection with the Equity Transfer and the Capital Increase in order to request the Governmental Authorities to take certain specific actions, this Agreement shall prevail over such agreements in full, and such agreements may only be used for requesting the Governmental Authorities to take such specific actions but not for establishing or evidencing the rights and obligations of the parties with respect to the matters provided for by such agreements. If there is any conflict between this Agreement and the Articles of Association, the Parties agree that this Agreement shall prevail to the extent permitted by laws.
