1.1 Amendment. Section 1.4(a) of the Share Exchange Agreement is hereby amended and restated in its entirety to read as follows:

(a) After the Closing, subject to the terms and conditions set forth herein, the Sellers shall have the contingent right to receive additional consideration from Purchaser based on the performance of Purchaser and its Subsidiaries, including the Company, for the fiscal year ended December 31, 2019 (the “2019 Earnout Year”) and the fiscal year ended December 31, 2020 (the “2020 Earnout Year” and each such fiscal year, an “Earnout Year” and such two-year fiscal period, the “Earnout Period”) if the requirements as set forth in this Section 1.4 are met. In the event that the Purchaser Adjusted Net Income for the 2019 Earnout Year is equal to or greater than One Hundred and Eighty Million Renminbi (RMB180,000,000) (the “2019 Earnout Target”), then, subject to the terms and conditions of this Agreement, the Sellers shall be entitled to receive from the Purchaser, as additional consideration for the purchase of the Purchased Shares, an additional Five Million (5,000,000) Purchaser Ordinary Shares (subject to equitable adjustment for share splits, share dividends, combinations, recapitalizations and the like after the Closing, including to account for any equity securities into which such shares are exchanged or converted) (the “2019 Earnout Shares”). In the event that the Purchaser Adjusted Net Income for the 2020 Earnout Year is equal to or greater than One Hundred and Eighty-Two Million Renminbi (RMB182,000,000) (the “2020 Earnout Target” and together with the 2019 Earnout Target, the “Earnout Targets”), then, subject to the terms and conditions of this Agreement, the Sellers shall be entitled to receive from the Purchaser, as additional consideration for the purchase of the Purchased Shares, an additional Five Million (5,000,000) Purchaser Ordinary Shares (subject to equitable adjustment for share splits, share dividends, combinations, recapitalizations and the like after the Closing, including to account for any equity securities into which such shares are exchanged or converted) (the “2020 Earnout Shares”, and collectively with the 2019 Earnout Shares, the “Earnout Shares”)). In the event that an Earnout Target is not met for any Earnout Year, the Sellers shall not be entitled to receive any Earnout Shares for such Earnout Year; provided, that in the event that the aggregate Purchaser Adjusted Net Income for both Earnout Years combined is at least Three Hundred and Sixty-Two Million Renminbi (RMB362,000,000) (the “Aggregate Earnout Target”), the Sellers shall be entitled to receive any Earnout Shares that they otherwise did not receive (the “Alternative Earnout”). For the avoidance of doubt, any determination of the Purchaser Adjusted Net Income that is not otherwise in Renminbi will be expressed in Renminbi by converting the applicable currency to Renminbi using the applicable exchange rate as of the last day of the applicable Earnout Year.”
