Each of the Reporting Persons and certain other shareholders of the Company has agreed to roll over certain ordinary shares (including ordinary shares represented by ADS) he or it beneficially owns (the “Rollover Shares,” and the holder thereof, “Rollover Shareholders”) in connection with the Merger in accordance with the terms and conditions of the relevant rollover and support agreement entered into with Parent dated October 11, 2023 (the “Support Agreement”).

The descriptions of the Merger, the Merger Agreement, the Equity Commitment Letters and the Support Agreement set forth in Item 4 below are incorporated by reference in their entirety into this Item 3.

Item 4. Purpose of Transaction.

On August 21, 2022, Mr. Sizhen Wang submitted a non-binding proposal (the “Proposal”) to the Company’s board of directors related to the proposed acquisition of all of the ordinary shares, including ordinary shares represented by ADS, not beneficially owned by him or any of his affiliates for cash consideration equal to US$0.272 per ordinary share or US$1.36 per ADS (the “Proposed Transaction”).

On October 11, 2023, the Company entered into the Merger Agreement with Parent and Merger Sub. Pursuant to the Merger Agreement, Merger Sub will be merged with and into the Company, with the Company continuing as the surviving company and a wholly owned subsidiary of Parent. At the effective time of the Merger (the “Effective Time”), each ordinary share and each ADS issued and outstanding immediately prior to the Effective Time will be cancelled and cease to exist in exchange for the right to receive US$0.272 per ordinary share or US$1.36 per ADS (less applicable fees, charges and expenses payable by ADS holders pursuant to the depositary agreement, dated June 18, 2020, entered into by and among the Company, the Bank of New York Mellon (the “Depositary”) and all holders and beneficial owners of ADSs issued thereunder), in each case, in cash, without interest and net of any applicable withholding taxes, except for (a) the Rollover Shares, which will be cancelled without payment of any cash consideration therefor, (b) ordinary shares (including ordinary shares represented by ADSs) owned by Parent, Merger Sub or the Company or any of their subsidiaries or held in the Company’s treasury, which will be cancelled without payment of any consideration therefor, (c) ordinary shares (including ordinary shares represented by ADSs) recorded under the name of the Depositary as member in the register of members of the Company and reserved for issuance and allocation pursuant to the Company share incentive plans, which will be cancelled without payment of any consideration therefor (such ordinary shares set forth in (a), (b) and (c), the “Excluded Shares”), and (d) ordinary shares that are issued and outstanding immediately prior to the Effective Time and that are held by shareholders of the Company who shall have validly exercised and not effectively withdrawn or lost their rights to dissent from the Merger in accordance with Section 238 of the Companies Act (as amended) of the Cayman Islands (the “Dissenting Shares”), which will be cancelled at the Effective Time and will entitle the holders thereof to receive the payment of the fair value of such Dissenting Shares held by them determined in accordance with the provisions of Section 238 of the Companies Act (as amended) of the Cayman Islands.

On October 11, 2023, the Company announced a change of the ratio of its ADS to ordinary shares from one (1) ADS representing five (5) ordinary shares to one (1) ADS representing fifteen (15) ordinary shares on or about October 26, 2023. Assuming the completion of such change of ratio, the holder of ADSs (other than the Excluded Shares) shall be entitled to receive US$4.08 in cash per ADS.

Each of the Reporting Persons has also agreed to upon the terms and subject to the conditions of the Support Agreement, cancel the Rollover Shares beneficially owned by him or it and receive no cash consideration for cancellation of the Rollover Shares in accordance with the Merger Agreement in exchange for newly issued shares in Parent.
