Amendment to Call Option Agreement

认购期权协议修正协议

鉴于：乙方持有丙方 99.9%的股权权益。甲方与丙方签订了技术咨询与服务协议、业务合作合同等一系列控制性协议（“ 控制协议”）。

Whereas: Party B holds 99.9% of the equity interest in Party C. Party A and Party C have executed a Technical Consultation and Service Agreement, Business Cooperation Agreement and other control agreements (the “Control Agreements”).

现各方协商一致，达成如下协议：

Now therefore, upon mutual discussion and negotiation, the Parties have reached the following agreement:

Sale and Purchase of Equity Interest

Option Granted

鉴于甲方向乙方支付了人民币 1元作为对价，且乙方确认收到并认为该对价足够，乙方在此不可撤销地同意，在中国法律允许的前提下，甲方可以按照自行决定的行使步骤，并按照本协议第 1.3条所述的价格，要求乙方履行和完成中国法律要求的一切审批和登记手续，使得甲方可以随时一次或多次从乙方购买，或指定一人或多人 (“被指定人”)从乙方购买乙方所持有的丙方的全部或部分股权 (“股权购买权”)。甲方的该股权购买权为独家的。除甲方和被指定人外，任何第三人均不得享有股权购买权或其他与乙方股权有关的权利。丙方特此同意乙方向甲方授予股权购买权。本款及本协议所规定的“人”指个人、公司、合营企业、合伙、企业、信托或非公司组织。

In consideration of the payment of RMB 1 by Party A, the receipt and adequacy of which is hereby acknowledged by Party B, Party B hereby irrevocably agrees that, on the condition that it is permitted by the PRC laws, Party A has the right to require Party B to fulfill and complete all approval and registration procedures required under PRC laws for Party A to purchase, or designate one or more persons (each, a “Designee”) to purchase, Party B’s equity interests in Party C, once or at multiple times at any time in part or in whole at Party A’s sole and absolute discretion and at the price described in Section 1.3 herein (such right being the “Equity Interest Purchase Option”). Party A’s Equity Interest Purchase Option shall be exclusive. Except for Party A and the Designee(s), no other person shall be entitled to the Equity Interest Purchase Option or other rights with respect to the equity interests of Party B. Party C hereby agrees to the grant by Party B of the Equity Interest Purchase Option to Party A. The term “person” as used herein shall refer to individuals, corporations, partnerships, partners, enterprises, trusts or non- corporate organizations.

Steps for Exercise of Equity Interest Purchase Option

甲方行使其股权购买权以符合中国法律和法规的规定为前提。甲方行 使股权购买权时，应向乙方发出书面通知(“股权购买通知”)，股权购买通知应载明以下事项： (a)甲方关于行使股权购买权的决定； (b)甲方拟从乙方购买的股权份额(“被购买股权”) ；和(c)被购买股权的购买日 /转让日。

Subject to the provisions of the laws and regulations of China, Party A may exercise the Equity Interest Purchase Option by issuing a written notice to Party B (the “Equity Interest Purchase Option Notice”), specifying: (a) Party A’s decision to exercise the Equity Interest Purchase Option; (b) the portion of equity interests to be purchased from Party B (the “Optioned Interests”); and (c) the date for purchasing the Optioned Interests and/or the date for transfer of the Optioned Interests.

Equity Interest Purchase Price

被购买股权的买价（“基准买价”）应为中国法律所允许的最低价格。如果在甲方行权时中国法律要求评估股权，各方通过诚信原则另行商 定，并在评估基础上对该股权买价进行必要调整，以符合当时适用之任 何中国法律之要求（统称“股权买价”）。如果由于适用法律要求，导致甲方向乙方实际支付的股权买价非为零元，则乙方应当按照甲方的 要求，并以合法的形式将乙方取得的股权买价立即返还给甲方或被指 定人。

The purchase price of the Optioned Interests (the “Base Price”) shall be the lowest price allowed by the laws of China. If appraisal is required by the laws of China at the time when Party A exercises the Equity Interest Purchase Option, the Parties shall negotiate in good faith and based on the appraisal result make necessary adjustment to the Equity Interest Purchase Price so that it complies with any and all then applicable laws of China (collectively, the “Equity Interest Purchase Price”). If the Equity Interest Purchase Price actually paid by Party A is not nil pursuant to the requirements of applicable laws, Party B shall immediately return to Party A or its Designee the Equity Interest Purchase Price received by Party B at the instruction of Party A and in compliance with applicable laws.

Transfer of Optioned Interests

甲方每次行使股权购买权时：

For each exercise of the Equity Interest Purchase Option:

Party B shall cause Party C to promptly convene a shareholders’ meeting, at which a resolution shall be adopted approving Party B’s transfer of the Optioned Interests to Party A and/or the Designee(s);

Amendment to Call Option Agreement

认购期权协议修正协议

Party B shall obtain written statements from the other shareholders of Party C giving consent to the transfer of the equity interest to Party A and/or the Designee(s) and waiving any right of first refusal related thereto;

The relevant Parties shall execute all other necessary contracts, agreements or documents, obtain all necessary government licenses and permits and take all necessary actions to transfer valid ownership of the Optioned Interests to Party A and/or the Designee(s), unencumbered by any security interests, and cause Party A and/or the Designee(s) to become the registered owner(s) of the Optioned Interests. For the purpose of this Section and this Agreement, “security interests” shall include securities, mortgages, third party’s rights or interests, any stock options, acquisition right, right of first refusal, right to offset, ownership retention or other security arrangements, but shall be deemed to exclude any security interest created by this Agreement and Party B’s Equity Pledge Agreement. “Party B’s Equity Pledge Agreement” as used in this Section and this Agreement shall refer to the Equity Pledge Supplementary Agreement (“Party B’s Equity Pledge Agreement”) executed by and among Party A, Party B and Party C as of the date hereof, whereby Party B pledges all of its equity interests in Party C to Party A, in order to guarantee Party C’s performance of its obligations under the Control Agreements executed by and between Party C and Party A.
