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

trusts or non-corporate organizations. 

  
 1 

	 	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”).

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

Designee (whichever is applicable), in accordance with the provisions of this Agreement and the Equity Interest Purchase Option Notice regarding the Optioned Interests;
