(2)	Party B agrees to hereby grant Party A and Party A agrees to accept an option to purchase the equity interest in Party C held by Party B in whole or in part.

NOW, THEREFORE, the Parties agree as follows upon negotiation:

Article 1 Purchase and Sale of Equity Interest

1.1Option Granted

The Existing Shareholders hereby irrevocably grant 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 the Existing Shareholders in one transaction or a series of transactions at any time in part or in whole at Party A’s sole and absolute discretion to the extent permitted by the PRC laws and at the price described in Article1.3 herein (“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 the Existing Shareholders. Party C hereby agrees to the grant by the Existing Shareholders of the Equity Interest Purchase Option to Party A. The Existing Shareholders hereby waive their respective right of first refusal with respect to the equity interests in Party C under Party C’s Articles of Association and the PRC laws, and hereby irrevocably agree to transfer the equity interests in Party C to Party A and/or the Designee(s). The term “person” as used in this paragraph and this Agreement shall refer to an individual, corporation, partnership, partner, enterprise, trust, or non-corporate organization.

1.2Steps for Exercise

Party A shall exercise its Equity Interest Purchase Option subject to the PRC laws and regulations. When Party A exercises the Equity Interest Purchase Option, a written notice shall be issued to the

Existing Shareholders (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 portion of equity interests to be purchased by Party A or the Designee from the Existing Shareholders (the “Optioned Interests”); and (c) the date for purchasing the Optioned Interests or the date for the transfer of the Optioned Interests. Upon receipt of the Equity Interest Purchase Option Notice, the Existing Shareholders shall transfer all the Optioned Interests to Party A and/or the Designee as set forth in Article 1.4 hereof.

1.3 Purchase Price of Equity Interest

The total price of Party A’s exercise of the Equity Interest Purchase Option to purchase all the Optioned Interests held by Party B in Party C shall be the then paid-in capital of the Optioned Interests or the lowest price permitted by the PRC laws, whichever lower; and in case that Party A exercises the Equity Interest Purchase Option to purchase part of the Optioned Interests held by Party B in Party C, the purchase price shall be calculated pro rata. If the PRC laws require valuation of the equity interest at the time of Party A’s exercise, the Parties shall negotiate separately in good faith and make necessary adjustments to such purchase price on the basis of valuation to comply with the then applicable PRC laws (collectively referred to as the “Equity Interest Purchase Price”). Party B shall, within ten (10) days after receiving the Equity Interest Purchase Price and legally paying/withholding the relevant taxes (if any) in full, give the balance thereof gratuitously to Party A or the person designated by Party A.

1.4.4The Existing Shareholders shall, within thirty (30) days after the receipt of the Equity Interest Purchase Option Notice, sign all other requisite contracts, agreements or documents with relevant parties, obtain all requisite governmental approvals and consents, and take all necessary actions, to transfer the valid ownership of the Optioned Interests to Party A and/or the Designee(s) free of any security interest and cause Party A and/or the Designee(s) to become the registered owner of the Optioned Interests. For the purpose of this paragraph and this Agreement, “security interest” shall include security, pledge, third party’s right or interest, any stock option, acquisition right, right of first refusal, right to offset, retention of title, or other security arrangements, but shall, for the sake of clarity, exclude any security interest created by this Agreement, the Equity Interest Pledge Agreement of the Existing Shareholders, and the Power of Attorney of the Existing Shareholders. “Equity Interest Pledge Agreement of the Existing Shareholders” as used in this Agreement shall refer to the Equity Interest Pledge Agreement executed by and among Party A, Party B and Party C on the date hereof and any modifications, amendments, or restatements thereto. “Power of Attorney of the Existing Shareholders” as used in this Agreement shall refer to the Power of Attorney executed by Party B on the date hereof and granted to Party A and any modifications, amendments, or restatements thereto.
