2.	Party B agrees to grant Party A an exclusive option right pursuant to this Agreement, and Party A agrees to accept such exclusive option right upon exercise of which to purchase all or part of the equity interests held by Party B in Party C.

In this regard, the Parties have reached the following agreement upon mutual discussion and negotiation:

1.	Sale and Purchase of Equity Interest

1.1

Option Granted

Party B hereby irrevocably 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 one or more times at any time in part or in whole at Party A’s sole and absolute discretion at the price described in Section 1.3 herein to the extent permitted by PRC laws (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. Each of Party B hereby waives its respective preemptive right regarding Party C’s equity under Party C’s articles of association and PRC laws, and hereby irrevocably agrees to transfer Party C’s equity to Party A and/or the Designee. The term “person” as used herein shall refer to individuals, corporations, partnerships, partners, enterprises, trusts or non-corporate organizations.

1.2

Steps for Exercise of the Equity Interest Purchase Option

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 or the Designee(s)’ decision to exercise the Equity Interest Purchase Option; (b) the respective 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. If Party A and/or other foreign-invested or foreign entities designated by Party A are permitted to directly hold part or all of Party C’s equity interests and engage in foreign investment restriction/prohibition business through Party C under the laws and regulations of PRC, Party A shall issue the Equity Interest Purchase Option Notice as soon as practicable. The proportion of Party C’s equity interests that the Designee(s) purchase(s) from Party B shall not be less than the maximum limit of Party C’s equity interests permitted under PRC laws to be held by Party A and/or other foreign-invested or foreign entities designated by Party A.

1.3

Equity Interest Purchase Price

The total price for the purchase by Party A of all equity interest held by Party B upon exercise of the Equity Interest Purchase Option by Party A shall equal to the amount of registered capital contributed by Party B in Party C for such Optioned Interests (or such price may be as set forth in the equity share transfer contract 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, if required by Party A); 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 is higher than the aforementioned price, then the purchase price shall be such minimum price permitted by PRC law (collectively, the “Equity Interest Purchase Price”).

1.4

Transfer of Optioned Interests

For each exercise of the Equity Interest Purchase Option:

1.4.1

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);

1.4.2

Party B shall obtain written statements from the other shareholders of Party C giving consent to the transfer of the Optioned Interests by Party B to Party A and/or the Designee(s) and waiving any right of first refusal with respect thereto;

1.4.3

Party B shall execute an share transfer contract with respect to each transfer with Party A and/or each Designee (whichever is applicable), in accordance with the provisions of this Agreement and the Equity Interest Purchase Option Notice regarding the Optioned Interests;

1.4.4

Related Parties shall execute all other necessary contracts, agreements or documents with relevant parties, obtain all necessary government approvals and permits, and conduct all necessary actions, so as 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, Party B’s Equity Interest Pledge Agreement and Party B’s Power of Attorney. “Party B’s Equity Interest Pledge Agreement” as used in this Agreement shall refer to the Interest Pledge Agreement executed by and among Party A, Party B and Party C on the date hereof and any modification, amendment and restatement thereto.; “Party B’s Power of Attorney” as used in this Agreement shall refer to the Power of Attorney executed by Party B on the date hereof granting Party A with a power of attorney and any modification, amendment and restatement thereto.

Party C hereby grants Party A an irrevocable and exclusive right to purchase, or Designee(s) to purchase the any part of or all of the assets of Party C at Party A’s sole and absolute discretion to the extent permitted by PRC laws and at the price permitted by PRC laws. Under such circumstances, Party A or the Designee(s) and Party C shall otherwise execute an asset transfer contract to agree on the terms and conditions of such asset transfer. “Assets” under this contract refer to assets directly or indirectly owned or controlled by the company from time to time and related to the company’s business operations, including current assets, capital equity for outbound investment, fixed assets, and intangible assets (including but not limited to patent and non-patented technology), deferred assets, the available benefits under all contracts entered into, and any other benefits that should be obtained by the company, including assets directly or indirectly owned or controlled by the company’s branches and offices from time to time.
