		1	Option

 

		1.1	Grant of option

 

Party B hereby irrevocably grants
Party A an exclusive option without any additional conditions. According to the option, Party A shall have the right, in accordance
with the exercise steps determined by Party A at its own discretion as permitted by PRC law, at any time to purchase or designate
one or more persons (“Designated Person(s)”) to purchase all or part of Party C’s equity interests held by Party

in Sub-clause 1.3 hereof. Any third parties other than Party A and/or Designated Person(s) shall not have the Exclusive Option.
The term “person” stipulated in this Agreement shall include individuals, corporations, joint ventures, partnerships,
enterprises, trusts or unincorporated organizations.

Annex I hereto, specifying the equity interests to be purchased from Party B (“Purchased Equity Interests”) or the
total amount of assets to be purchased from Party C and the purchase method.

 

Within seven (7) business days
after receipt of the Purchase Notice by Party B, Party B shall enter into an equity interest transfer contract with Party A and/or
Designated Person(s) according to the requirements of the Purchase Notice, or Party C shall enter into an asset transfer contract

PRC at that time require an assessment of the purchased equity interests or assets or impose other restrictive provisions on the
price of the equity interests or assets, the purchase price of the Purchased Equity Interests (“Equity Interest Purchase
Price”) or the purchase price of the purchased assets (“Asset Purchase Price”) shall be subject to the nominal
or symbolic price; if the laws and regulations of the PRC applicable to the exercise of the Exclusive Option by Party A do not

price (“Original Investment Price”) paid by Party B for the Purchased Equity Interests, and the Asset Purchase Price
shall be equal to the book value of the assets.

 

		1.3.2	If the laws and regulations of the PRC applicable to the exercise of the Exclusive Option by Party
A require an assessment of the purchased equity interests or assets or impose other restrictive provisions on the price of the
equity interests or assets, Party A and Party B agree that the purchase price shall be the minimum price permitted by the applicable
law. If the minimum price permitted by the applicable law is higher than the Original Investment Price of the Purchased Equity
