It is accordingly agreed that the parties shall be entitled to injunction to prevent breaches of this Agreement and to enforce specifically the terms and provisions of this Agreement.

SECTION 8.03 Calculation of Losses.

Each of the Seller Parties agrees that in assessing the amount of damages for a breach of representations and warranties, covenants and agreements under this Agreement, there shall be taken into account that: (i) in calculating the loss or damage that the Investors may suffer as a result of any claim made by the Investors under this Agreement, any payment made by the Company to reimburse the Investors for their losses will in itself diminish the value of the Investors’ investment in the Company and, accordingly, such payment should be taken into account in calculating the Investors’ loss or damage; and (ii) the Investors shall be entitled to be compensated for, but not limited to, the decrease in value (including loss of bargain) of all Series A Preferred Shares or Ordinary Shares arising from conversion thereof held by the Investors as a result of any inaccuracy or breach of representations and warranties, covenants and agreements or breach of any other provision of this Agreement.

SECTION 8.04 Limitation of Liabilities.

Notwithstanding anything to the contrary herein, absent fraud, intentional misrepresentation and willful misconduct:

(a) the maximum aggregate monetary liability of the Seller Parties to the Indemnified Parties for any indemnification under this Agreement and the other Transaction Documents shall not exceed the Purchase Price actually paid by such Investors.

(b) if the losses suffered by the Indemnified Parties are, individually or in the aggregate less than US$50,000 (or its equivalent in other currencies), the Seller Parties shall not be required to indemnify the Indemnified Parties for such losses.

(c) in any event the Founders’ indemnification obligation under this Agreement and the other Transaction Documents is secondary to the Group Companies.

(d) the Founders may, in their sole discretion, elect to satisfy the entirety of their obligation under this Agreement and the other Transaction Documents by transferring the Ordinary Shares in whole or in part held by the BVI Companies to the Indemnified Parties at no cost, which shall be the exclusive remedy of the Indemnified Parties upon such election by the Founders. For the avoidance of doubt, the indemnification obligations of the other Seller Parties shall be unaffected by this Section 8.04(d). In computing the number of Ordinary Shares to be transferred hereunder, the value of the Ordinary Shares held by the BVI Companies shall be the fair value thereof at the time of the indemnification claim, as determined by the Board in good faith.

SECTION 8.05 Governing Law.

This Agreement shall be governed by and construed exclusively in accordance with the laws of the Hong Kong SAR without regard to principles of conflicts of law thereunder.

SECTION 8.06 Survival.

Except for Section 3.16, the representations and warranties made herein shall survive two years after the Closing. The covenants and agreements made herein shall survive any investigation made by any party hereto and the Closing.

SECTION 8.07 Successors and Assigns.

Except as otherwise expressly provided herein, the provisions hereof shall inure to the benefit of, and be binding upon, the successors, assigns, heirs, executors and administrators of the parties hereto whose rights or obligations hereunder are affected by such provisions. Notwithstanding anything contrary in this Agreement, this Agreement and the rights and obligations herein may be assigned or transferred by each Investor to (A) its partners or former partners in accordance with partnership interests, (B) a wholly-owned subsidiary or a parent corporation that owns all of the capital stock of such Investor, (C) its members or former members in accordance with their interest in the limited liability company, or (D) any of its Affiliates; provided that in each case the transferee will agree by executing a Deed of Adherence in the form attached hereto as Exhibit D to be subject to the terms of this Agreement to the same extent as if it were an original Investor hereunder. For purposes of this Section 8.07, “Affiliate” shall mean, in respect of a Person, any other Person that, directly or indirectly, through one or more intermediaries, Controls, is Controlled by, or is under common Control with, such Person, and (a) in the case of a natural Person, shall include, without limitation, such Person’s spouse, parents, children, siblings, mother-in-law and father-in-law and brothers and sisters-in-law, (b) in the case of any Investor, shall include any Person who holds shares as a nominee for such Investor, and (c) in respect of any Investor, shall also include (i) any shareholder of such Investor, (ii) any entity or individual which has a direct and indirect interest in such Investor (including, if applicable, any general partner or limited partner) or any fund manager thereof; (iii) any Person that directly or indirectly Controls, is Controlled by, under common

Control with, or is managed by such Investor, its shareholder, the general partner or the fund manager of such Investor or its shareholder, (iv) the relatives of any individual referred to in (ii) above, and (v) any trust Controlled by or held for the benefit of such individuals. “Person” shall mean any individual, corporation, partnership, limited partnership, proprietorship, association, limited liability company, firm, trust, estate or other enterprise or entity. “Control” shall mean the power or authority, whether exercised or not, to direct the business, management and policies of a Person, directly or indirectly, whether through the ownership of voting securities, by contract or otherwise; provided, that such power or authority shall conclusively be presumed to exist upon possession of beneficial ownership or power to direct the vote of more than fifty percent (50%) of the votes entitled to be cast at a meeting of the members or shareholders of such Person or power to control the composition of a majority of the board of directors of such Person. The terms “Controlled” and “Controlling” have meanings correlative to the foregoing. For the avoidance of doubt, no Investor shall be deemed to be an Affiliate of the Company. Notwithstanding the foregoing, the parties acknowledge and agree that (a) “GGV Capital” is commonly used to describe a variety of entities (collectively, the “GGV Entities”) that are affiliated by ownership or operational relationship and engaged in a broad range of activities related to investing and securities trading and (b) notwithstanding any other provision of this Agreement to the contrary, this Agreement shall not be binding on, or restrict the activities of, any (i) GGV Entity outside of the GGV China Sector Group or (ii) entity primarily engaged in investment and trading in the secondary securities market. For purposes of the foregoing, the “GGV China Sector Group” means all GGV Entities (whether currently existing or formed in the future) that are principally focused on companies located in, or with connections to, the PRC.

In such event, the parties shall use best 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.
