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:

1. 股权买卖

Sale and Purchase of Equity Interest

1.1            授予权利

Option Granted

乙方在此不可撤销地、无条件地授予甲方一项专有权（“股权购买权”），允许甲方在中国法律允许的前提下，按照甲方自行决定的行使步骤，并按照本协议第1.3条所述的价格，随时一次或多次从乙方购买或指定一人或多人（“被指定人”）从乙方购买其届时所持有的丙方的全部或部分股权。除甲方和被指定人外，任何其他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。

Party B hereby irrevocably and unconditionally grants Party A an irrevocable and exclusive right to purchase, or designate one or more persons (each, a “Designee”) to purchase the equity interests in Party C then held by Party B once or at multiple times at any time in part or in whole at Party A’s sole and absolute discretion to the extent permitted by Chinese laws and at the price described in Section 1.3 herein (such right being the “Equity Interest Purchase Option”). 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.

2

1.2           行使步骤

Steps for Exercise of the 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，及被指定人的名称（若有）；(b)甲方或被指定人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, and the name of the Designee(s) if any; (b) the portion of equity interests to be purchased by Party A or the Designee from Party B (the “Optioned Interests”); and (c) the date for purchasing the Optioned Interests or the date for the transfer of the Optioned Interests.

1.3           股权买价

Equity Interest Purchase Price

Optioned Interests 被购买股权

甲方行使股权购买权购买乙方持有的全部被购买股权的总价应为10元（或以甲方（或被指定人）与乙方另行签订的股权转让合同中所列的为准，前提是该价格不违反中国法律法规的规定且被甲方认可）（“基准买价”）；甲方行使股权购买权购买乙方在丙方持有的部分被购买股权时，股权买价按照比例计算。如果在甲方行使股权购买权时，中国法律对被购买股权的转让价格有任何强制性规定，导致法律允许的最低价格高于基准买价，则转让价格应以中国法律所允许的该最低价格为准（统称“股权买价”），在此种情况下，乙方应以中国法律允许的方式将其获得的所有高出基准买价部分的金额及时赠予甲方或甲方指定的任何人。

The total price for the purchase by Party A of all Optioned Interests held by Party B upon exercise of the Equity Interest Purchase Option by Party A shall be RMB 10 (or the price as set forth in the equity transfer agreement to be executed between Party A (or the Designee) and Party B separately, provided that such price does not violate PRC laws and regulations and is acceptable to Party A) (the “Base Price”); if Party A exercises the Equity Interest Purchase Option to purchase part of the Optioned Interests held by Party B in Party C, then the purchase price shall be calculated on a pro rata basis. If at the time when Party A exercises the Equity Interest Purchase Option, the PRC laws impose mandatory requirements on the purchase price of such Optioned Interests, such that the minimum price permitted under PRC law exceeds the Base Price, then the purchase price shall be such minimum price permitted by PRC law (collectively, the “Equity Interest Purchase Price”), in which case the Party B shall promptly donate all of the amount exceeding the Base Price received by it to Party A or any other person designated by Party A in the manner permitted by the applicable PRC laws.

Any Party may waive the terms and conditions of this Agreement, provided that such a waiver must be provided in writing and shall require the signatures of the Parties. No waiver by any Party in certain circumstances with respect to a breach by other Parties shall operate as a waiver by such a Party with respect to any similar breach in other circumstances.
