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 a 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 (less applicable fees, charges and expenses payable by ADS holders pursuant to the depositary agreement), without interest and net of any applicable withholding taxes.

If the Merger is completed, the Company will become a wholly owned subsidiary of Parent and Company’s ADSs would become eligible for termination of registration pursuant to Section 12(g)(4) of the Act and would be delisted from the NASDAQ Global Market.

TERMINATION FEE

3.1 If the Merger is not consummated and the Parent Termination Fee becomes payable by Parent pursuant to Section 8.06(b) of the Merger Agreement, and any party hereto is a Defaulting Party (as defined below), notwithstanding anything provided under the Limited Guaranties, (a) the Defaulting Party shall be responsible for the entire Parent Termination Fee payable by Parent under Section 8.06(b) of the Merger Agreement and shall promptly pay an amount equal to the Parent Termination Fee to Parent by wire transfer of same day fund within one (1) Business Day following the termination of the Merger Agreement pursuant to Section 8.03(a) or Section 8.03(b) thereof; (b) in the event any of the Company’s fees and expenses shall become payable by Parent in accordance with Section 8.06(d) of the Merger Agreement, the Defaulting Party shall be responsible for all such fees and expenses payable by Parent; and (c) in the event that a Non-Defaulting Party’s (or the respective Guarantor’s) liabilities under the relevant Limited Guarantee become due and payable, the Defaulting Party shall indemnify such Non-Defaulting Party (or the respective Guarantor) in full for all payments made by, and all fees and out-of-pocket expenses incurred by, such Non-Defaulting Party (or the respective Guarantor) under such Limited Guarantee (the obligations of the Defaulting Party under this Section 3.1, collectively, the “Default Obligations”). If there is more than one Defaulting Party, each Defaulting Party shall be responsible for its Pro Rata Portion of the Default Obligations. A Defaulting Party’s “Pro Rata Portion” for the purposes of this Section 3.1 is a fraction, the numerator of which is such Defaulting Party’s Contemplated Ownership Percentage and the denominator of which is the aggregated Contemplated Ownership Percentage of all Defaulting Parties.

3.2 If the Merger is not consummated and the Parent Termination Fee becomes payable by Parent pursuant to Section 8.06(b) of the Merger Agreement, but no party is a Defaulting Party, then each party who (or whose Affiliate) also executes a Limited Guarantee shall be responsible for its (or its Affiliate’s) Guaranteed Percentage (as defined in the respective Limited Guarantee) of (i) Parent Termination Fees under Section 8.06(b) and (ii) Company’s fees and expenses under Section 8.06(d) of the Merger Agreement ((i) and (ii) collectively, the “Guaranteed Obligations”) in accordance with and subject to the terms and conditions of the Limited Guarantee executed by such party.

3.3 A “Defaulting Party” is a party hereto, the failure of whom or whose Affiliate to perform its obligation under this Agreement or, to the extent it is a party, the Support Agreement or the Equity Commitment Letter, results in the failure of the Merger to consummate. A “Non-Defaulting Party” is a party hereto who is not a Defaulting Party.

3.4 The parties shall be entitled to receive any termination, break-up or other fees or amounts payable to Parent by the Company pursuant to the Merger Agreement, to be allocated ratably in proportion to their respective Contemplated Ownership Percentages, net of the costs and expenses incurred by the Consortium in connection with the Transaction, including the fees, expenses and disbursements of Consortium Advisors retained by the Consortium (but other than fees and costs of any Separate Advisors who were retained by a party in accordance with Section 4.5 unless otherwise agreed to by the parties in writing).

CERTAIN FEES AND EXPENSES

4.2 If the Merger is not consummated and no party hereto is a Defaulting Party, the parties agree that (i) each party shall bear the fees and out-of-pocket expenses payable by such party in connection with the Transactions incurred prior to the termination of this Agreement; and (ii) each party shall bear its portion (based on such party’s respective Guaranteed Percentage) of the Consortium Expenses. Notwithstanding the foregoing, (i) the fees, expenses and disbursements of any Separate Advisors engaged pursuant to Section 4.5 and the other out-of-pocket costs and expenses incurred in connection with any legal due diligence investigation conducted by CICC with respect to the Company, including any fees, expenses and disbursements payable to the Separate Advisors retained for such purposes (collectively, the “DD Expenses”), shall be borne solely by CICC, Surrich International Company Limited and CCB (Beijing) Investment Fund Management Co., Ltd., in proportion to such party’s respective Guaranteed Percentage, (ii) the fees, expenses and disbursements of any Separate Advisors engaged pursuant to Section 4.5 and the other out-of-pocket costs and expenses incurred in connection with any due diligence investigation conducted by other Investor Members with respect to the Company shall be borne solely by such Investor Members, and (iii) for the avoidance of doubt, the sharing of any Guaranteed Obligation shall be governed by Section 3.2 and not by this Section 4.2.

4.3 Upon consummation of the Merger and from time to time thereafter, Parent shall or shall cause the Surviving Company to reimburse each party hereto for, or pay on behalf of such party, as the case may be, all DD Expenses, all Consortium Expenses and all other fees and out-of-pocket expenses incurred by Consortium Members in connection with the Merger (including reasonable costs and expenses incurred in the defense, response, pursuit or settlement of any disputes, subpoena, arbitration or litigation relating to this Agreement or the Transactions), other than the fees, expenses and disbursements of any Separate Advisors engaged pursuant to Section 4.5 (unless they constitute DD Expenses).

4.4 For the purpose of this Agreement, “Consortium Expenses” means all fees and out-of-pocket expenses incurred by the Consortium in connection with the Transactions (including without limitations, (i) fees, reasonable expense and disbursements of joint advisors and/or consultants of the Consortium (the “Consortium Advisors”), but excluding any fees, expenses and disbursement of any Separate Advisors retained by parties pursuant to Section 4.5 unless and only to the extent such appointment and expenses are otherwise agreed to by the parties in advance in writing, (ii) fees and expenses incurred in connection with the Escrow

Account(s) set up by Parent and each of the Sponsors pursuant to the terms of Equity Commitment Letters and Escrow Agreement(s), including the fees charged by the Escrow Agent (each as defined in the Equity Commitment Letters), and (iii) reasonable costs and expenses incurred in the defense, response, pursuit or settlement of any disputes, subpoena, arbitration or litigation relating to this Agreement or the Transactions (in which cases, whether such fees and expenses are incurred prior to the termination of this Agreement or not)), in each case as supported by invoice with reasonable detail and as confirmed by the Founder and CICC.

4.5 For the purpose of this Section 4, the Consortium Members agree that Skadden, Arps, Slate, Meagher & Flom LLP has been retained and shall act as U.S. legal counsel to the Consortium as a Consortium Advisor, and King & Wood Mallesons has been retained and shall act as PRC legal counsel to the Consortium as a Consortium Advisor. Each party may retain other advisor(s) (the “Separate Advisors”) if such party requires separate representation in connection with specific issues arising out of the Transaction, provided that such party shall (i) provide prior notice to other Consortium Members, and (ii) subject to Sections 4.1, 4.2, 4.3 and 5 be solely responsible for the fees and expenses of such Separate Advisors.

4.6 Without prejudice to anything set forth under Sections 4.1, 4.2 and 4.3, to the extent any Investor Member becomes a Failing Investor, the participation of which in the Transactions is terminated pursuant to Section 6.2, such Investor Member shall bear its portion to Consortium Expenses, the DD Expenses and such other fees and expenses incurred prior to the termination of its participation in the Transaction. For the avoidance of doubt, a Failing Investor which is a Defaulting Party shall bear the full amount of the Consortium Expenses, the DD Expenses and make other reimbursements pursuant to Section 4.1.

4.7 The provisions under this Section 4 constitute the entire agreement, and supersede in full, all prior agreements, understanding, negotiations and statements, both written and oral, among the parties hereto or any of their Affiliates with respect to the subject matter contained herein.

For the avoidance of doubt, nothing in this Section 6.1 shall prevent the Founder or any Affiliate or Representative of any Investor Member from taking any action in his capacity as a director or officer of the Company, if he determines, in his good faith judgment upon advice by the outside legal counsel of the Company, that failure to take such action is inconsistent with his fiduciary duties under applicable Law.

For the purpose of this Section 6.1, a “Competing Proposal” shall mean a proposal, offer or invitation to the Company, a party hereto or any of their respective Affiliates (other than the Transaction), that relates to a Competing Transaction.

6.2 Notwithstanding anything to the contrary under this Section 6, in the event that the Closing Conditions (other than the ODI Approval with respect to the Failing Investor (as defined below)) are satisfied or validly waived (subject to the requirements in Section 1.1), and the Consortium Members (other than the Failing Investor) are willing to proceed with the Closing, (A) the Founder shall be allowed to solicit, encourage, facilitate or otherwise invite new investor(s) to join the Consortium for the purpose of consummating the Transactions, and (B) such other Consortium Members, together with the new investor(s) so identified by the Founder, may proceed with the Closing by first terminating the participation in the Transactions of any Investor Member (a) that has not (or whose Affiliate has not) obtained the ODI Approval for its or its Affiliate’s participation in the Transaction as of the later of (x) the date that is six months prior to the Long Stop Date (which, for the purpose of this Agreement, does not include any extension permitted under the Merger Agreement) and (y) the date when the Closing Conditions (other than the ODI Approval with respect to the Failing Investor) are satisfied or validly waived (subject to the requirements in Section 1.1), or (b) that asserts (or whose Affiliate asserts) in writing its or its Affiliate’s unwillingness to fulfill its Commitment (a “Failing Investor”), such termination right to be exercised by the Founder; provided, that such termination shall not affect the rights of the remaining Consortium Members against such Failing Investor with respect to such failure or declination to fund, which rights shall be as provided in Section 3 and Section 4 hereof; provided however in the absence of any breach of its obligations under Section 2.5 hereof, a failure of any Investor Member to obtain the ODI Approval for its or its Affiliate’s participation in the Transaction shall not in any event, in and of itself constitute a breach by such Investor Member or any of its Affiliate of any terms of this Agreement, the Support Agreement, or the Equity Commitment Letters to which such Investor Member or any of its Affiliate is a party. In the event the Founder terminates a Failing Investor’s participation in the Transactions, the amount of such Failing Investor’s Equity Commitment shall be offered to new investors in such amounts as may be determined by the Founder. Notwithstanding anything to the contrary contained herein, (i) from and after the time an Investor Member becomes a Failing Investor as defined in sub-clause (b) of this Section 6.2, or the Founder terminates the participation in the Transactions of a Failing Investor as defined in sub-clause (a) of this Section 6.2, the approval or

consent of such Failing Investor shall not be required for any purposes under this Agreement, and (ii) CICC Healthcare will in no event be deemed as a Failing Investor and the Founder may in no event terminate CICC Healthcare’s participation in the Transactions, in connection with or as a result of any failure to obtain the ODI Approval required for Tianjin Kangyue’s participation in the Transactions.

6.3 The parties shall negotiate in good faith and enter into concurrently with the Effective Time a shareholders agreement governing their respective rights and obligations in the Parent after the consummation of the Transaction, which shall contain terms that are (subject to mutually agreed changes) consistent with the terms set forth in the SHA Term Sheet, and such other corporate governance and shareholders protective terms customary for a privately-held company as mutually agreeable to each Consortium Member. In the event that the Consortium Members are unable to agree on the terms of the shareholders’ agreement, the terms set forth in the SHA Term Sheet shall govern with respect to the matters set forth therein following the Effective Time and until such time as the Consortium Members enter into a shareholders’ agreement. “SHA Term Sheet” means the term sheet with respect to the key terms of shareholder rights and corporate governance of Parent attached hereto as Exhibit 1.

6.4 Without the prior written consent of each other Consortium Member, no Consortium Member may (and such Consortium Member shall cause its Affiliates not to), directly or indirectly, acquire Beneficial Ownership of any Shares or other Equity Securities in the Company.

MISCELLANEOUS

7.1 Effectiveness; Termination. This Agreement shall become effective on the date hereof and shall terminate (except with respect to Sections 3,4, 5 and 7) upon the earlier of (i) the Effective Time of the Merger and (ii) the termination of the Merger Agreement in accordance with its terms; provided, that any liability for failure to comply with the terms of this Agreement shall survive such termination.

7.2 Amendment. Any provision of this Agreement may be amended or waived if, and only if, such amendment or waiver is in writing and signed by each party hereto.

7.3 Severability. Any term or provision of this Agreement which is invalid or unenforceable in any jurisdiction shall, as to that jurisdiction, be ineffective to the extent of such invalidity or unenforceability without rendering invalid or unenforceable the remaining terms and provisions of this Agreement in any other jurisdiction. If any provision of this Agreement is so broad as to be unenforceable, such provision shall be interpreted to be only as broad as is enforceable.

7.4 Remedies. Except as otherwise provided herein, any and all remedies herein expressly conferred upon a party will be deemed cumulative with and not exclusive of any other remedy conferred hereby, or by law or equity upon such party, and the exercise by a party of any one remedy will not preclude the exercise of any other remedy. No failure or delay on the part of any party hereto in the exercise of any right hereunder will impair such right or be construed to

be a waiver of, or acquiescence in, any breach of any representation, warranty or agreement herein, nor will any single or partial exercise of any such right preclude other or further exercise thereof or of any other right. The parties hereby acknowledge and agree that irreparable damage would occur in the event that any of the provisions of this Agreement were not performed in accordance with their specific terms or were otherwise breached, and damages alone would not be sufficient remedy for any actual or threatened breach of this Agreement and that each party shall be entitled to seek the remedy of injunction, specific performance and other legal and equitable relief for any breach of this Agreement (without posting a bond or other security) in additional to any other remedies available to it at law or in equity.

7.5 Announcement. No announcements or other public statement regarding the subject matter of this Agreement shall be issued or made by Parent, Merger Sub or any Consortium Member or any of their respective Affiliates without the prior written consent of all Consortium Members, which consent shall not be unreasonably withheld, delayed or conditioned, except to the extent that any such announcements or statements are required by applicable Law, a court of competent jurisdiction, a regulatory body or securities exchange, and then only after the form and terms of such announcements or statements have been notified to the Consortium Members and the Consortium Members have had a reasonable opportunity to comment thereon, in each case to the extent reasonably practicable. Notwithstanding the foregoing, any Consortium Member may make any Schedule 13D filings, or amendments thereto, in respect of the Company that such Consortium Member reasonably believes is required under applicable Law without the prior written consent of the other Consortium Members, provided that such Consortium Member shall coordinate with the other Consortium Members in good faith regarding the content and timing of such filings or amendments in connection with the Transactions.
