	1.1	 Option Granted 

Party B hereby severally, but not jointly agrees to grant Party A an irrevocable and exclusive right to purchase the equity interests in Party
C that held by Party B, once or at multiple times at any time in part or in whole and at the price set forth in Article 1.3 hereof in accordance with the procedure promulgated by Party A in Party A’s sole and absolute discretion to the extent
