WHEREAS, prior to the effectiveness of the Registration Statement (as defined below) and as further described therein, Sinda Cayman will de-register in the Cayman Islands and register by way of continuation in the State of Delaware by filing a Certificate of Domestication to incorporate in the State of Delaware (the “Redomiciliation”) as Sinda Ltd., a Delaware corporation (“Sinda Delaware”), and references in this Agreement to the “Company” shall be to (i) Sinda Cayman, prior to the consummation of the Redomiciliation and (ii) Sinda Delaware, following consummation of the Redomiciliation;

WHEREAS, the Company has filed a registration statement on Form S-1 (File No. 333-296567) (together with any pre-effective or post-effective amendments thereto, the “Registration Statement”) with the Securities and Exchange Commission (“SEC”), in connection with the Company’s initial public offering (“IPO”) of shares of Common Stock pursuant to an underwriting agreement (the form of which is included as Exhibit A hereto, the “Underwriting Agreement”) to be entered into by the Company and certain underwriters party thereto (the “Underwriters”);

WHEREAS, the IPO will include a public offering and a private placement;

WHEREAS, concurrently with the completion of the IPO, as part of such private placement, the Company desires to issue and sell to the Investor, and the Investor desires to purchase from the Company in an offering exempt from the registration requirements of the Securities Act of 1933, as amended (the “Securities Act”) and in reliance on Section 4(a)(2) thereof, upon the terms and conditions set forth in this Agreement, such number of Shares (as defined below) of the Company’s Common Stock as provided in Section 1 of this Agreement; and

NOW, THEREFORE, in consideration of the foregoing and the mutual covenants, agreements and warranties herein contained, the parties hereby agree as follows:

1. Purchase and Sale of Stock.

1.1 Sale and Issuance of Common Stock.

(a) Subject to the terms and conditions of this Agreement, the Investor agrees to purchase from the Company, and the Company agrees to sell and issue to the Investor, a number of shares (collectively, the “Shares”) of Common Stock at a price per share equal to the per share public offering price set forth on the cover page of the final prospectus relating to the IPO (the “IPO Price”), rounded down and adjusted to the nearest whole share, such that after giving effect to the IPO (including any exercise of the underwriters’ over-allotment option thereunder), the Investor would beneficially own 5.0% of the Company’s outstanding common stock, provided that if the aggregate purchase price for such number of Shares would exceed US$110 million, such number of Shares to be purchased pursuant to this Agreement shall be reduced to the maximum number of Shares that could be purchased at the IPO Price for no more than an aggregate purchase price of US$110 million.

(b) All references to numbers of shares and prices per share in this Agreement shall be appropriately adjusted to reflect any stock dividend, stock split, reverse stock split, combination or other recapitalization or reclassification of shares by the Company (including the Redomiciliation) occurring after the date of this Agreement and prior to the determination of the IPO Price.

1.2 Closing. The purchase and sale of the Shares shall take place remotely via the exchange of documents and signature pages on the first business day immediately following the 30th calendar day following the pricing date of the IPO (which time and place are designated as the “Closing”), subject to the satisfaction or waiver of all the conditions set forth in Sections 4 and 5 hereof. At the Closing, the Investor shall make payment of the purchase price for the Shares by wire transfer in immediately available funds to the account specified by the Company against delivery to the Investor of the Shares registered in the name of the Investor or its nominee, which Shares shall be uncertificated shares.

2.13 Removal of Restrictive Legends. Following the expiration of the Lock-Up Period, in the event that the Shares are eligible to be transferred without restriction (including the requirement that the Company shall have timely filed any required current public information pursuant to Rule 144(c)) in accordance with Rule 144 under the Securities Act (“Rule 144”), the Company shall (x) instruct the Company’s transfer agent to issue new uncertificated (book-entry) instruments representing the Shares, which shall not contain such portion of the above legend that is no longer applicable, (y) take all actions with the Company’s transfer agent reasonably requested by the Investor to permit such un-legended Shares to be deposited into the account specified by the Investor to the Company in writing, including an opinion of counsel of the Company, and (z) instruct the Company’s transfer agent to cause such Shares to be assigned the same CUSIP as the shares of Common Stock that are then traded on the principal stock exchange on which the shares of Common Stock are then listed; provided that, the Investor shall deliver all documentation requested by the Company’s transfer agent in connection with the removal of legends.

If it authorizes or effects any split, reclassification or similar action in respect of its capital stock (including but not limited to the split and/or reclassification described in the Prospectus), such split, reclassification or other action shall be structured and effected in a manner that does not change or restart Investor’s holding period for all or any portion of the Shares for purposes of Rule 144 or any federal, state or foreign tax law.

Each such notice or other communication shall for all purposes of this Agreement be treated as effective or having been given (i) if delivered by hand, messenger or courier service, when delivered (or if sent via a nationally-recognized overnight courier service, freight prepaid, specifying next-business-day delivery, one (1) business day after deposit with the courier), (ii) if sent via mail, at the earlier of its receipt or five (5) days after the same has been deposited in a regularly-maintained receptacle for the deposit of the United States mail, addressed and mailed as aforesaid, or (iii) if sent via electronic mail, when directed to the relevant electronic mail address, if sent during normal business hours of the recipient, or if not sent during normal business hours of the recipient, then on the recipient’s next business day. In the event of any conflict between the Company’s books and records and this Agreement or any notice delivered hereunder, the Company’s books and records will control absent fraud or error.

7.8 Brokers or Finders. The Company shall indemnify and hold harmless the Investor from any liability for any commission or compensation in the nature of a brokerage or finder’s fee or agent’s commission (and the costs and expenses of defending against such liability or asserted liability) for which the Investor or any of its constituent partners, members, officers, directors, employees or representatives is responsible to the extent such liability is attributable to any inaccuracy or breach of the representations and warranties contained in Section 2.7, and the Investor agrees to indemnify and hold harmless the Company from any liability for any commission or compensation in the nature of a brokerage or finder’s fee or agent’s commission (and the costs and expenses of defending against such liability or asserted liability) for which the Company or any of its constituent partners, members, officers, directors, employees or representatives is responsible to the extent such liability is attributable to any inaccuracy or breach of the representations and warranties contained in Section 3.7.

7.9 Amendments and Waivers. Any term of this Agreement may be amended and the observance of any term of this Agreement may be waived (either generally or in a particular instance and either retroactively or prospectively), only with the written consent of the Company and the Investor.

7.10 Severability. If any provision of this Agreement becomes or is declared by a court of competent jurisdiction to be illegal, unenforceable or void, portions of such provision, or such provision in its entirety, to the extent necessary, shall be severed from this Agreement, and such court will replace such illegal, void or unenforceable provision of this Agreement with a valid and enforceable provision that will achieve, to the extent possible, the same economic, business and other purposes of the illegal, void or unenforceable provision. The balance of this Agreement shall be enforceable in accordance with its terms.

7.11 Entire Agreement. This Agreement and the documents referred to herein constitute the entire agreement between the parties. No party shall be liable or bound to any other party in any manner with regard to the subjects hereof or thereof by any warranties, representations or covenants except as specifically set forth herein or therein.

7.12 Specific Performance. The parties to this Agreement hereby acknowledge and agree that the Company would be irreparably injured by a breach of this Agreement by the Investor, and the Investor would be irreparably injured by a breach of this Agreement by the Company, and that money damages are an inadequate remedy for an actual or threatened breach of this Agreement because of the difficulty of ascertaining the amount of damage that will be suffered by the aggrieved party in the event that this agreement is breached. Therefore, each of the parties to this Agreement agree to the granting of specific performance of this Agreement and injunctive or other equitable relief in favor of the aggrieved party as a remedy for any such breach, without proof of actual damages, and the parties to this Agreement further waive any requirement for the securing or posting of any bond in connection with any such remedy. Such remedy shall not be deemed to be the exclusive remedy for breach of this Agreement, but shall be in addition to all other remedies available at law or in equity to the aggrieved party. If any term, provision, covenant or restriction of this Agreement is held by a court of competent jurisdiction to be invalid, void or unenforceable, the remainder of the terms, provisions, covenants and restrictions of this Agreement shall remain in full force and effect and shall in no way be affected, impaired or invalidated.
