Indemnifiable Loss from the Group Companies before the expiration of the Grace Period, the Key Holders shall not be obligated to indemnify the Indemnified Party with respect to such amount; provided, further, that the failure of any Group Company to
pay any Indemnifiable Loss to such Indemnitees is not solely due to disapproval of such payment by the Investors or the director appointed by the Investors. 



  
 15 














	7.4	 If an Investor or other Indemnitee believes that it has a claim that may give rise to an obligation of any
Warrantor pursuant to this Section 7, it shall give prompt notice thereof to the Warrantors and the other Investors stating specifically the basis on which such claim is being made, the material facts related thereto, and
the amount of the claim asserted. Any dispute related to this Section 7 shall be resolved pursuant to Section 8.15.

shares held by the Indemnitee or its Affiliates); the maximum aggregate liability of each Key Holder for indemnification to any Indemnitee under this Section 7 shall be limited to the equity interest of such Key Holder in

(i) no oral statements made by any Investor or its representatives on or after the date of this Agreement shall create an obligation, commitment or agreement to provide or assist the Company in obtaining any financing or investment,
(ii) the Company shall not rely on any such statement by any Investor or its representatives and (iii) an obligation, commitment or agreement to provide or assist the Company in obtaining any financing or investment may only be created by
a written agreement, signed by such Investor and the Company, setting forth the terms and conditions of such financing or investment and stating that the parties intend for such writing to be a binding obligation or agreement. Each Investor shall
have the right, in its sole and absolute discretion, to refuse or decline to participate in any other financing of or investment in the Company, and shall have no obligation to assist or cooperate with the Company in obtaining any financing,
investment or other assistance.

rights, powers and remedies which such Party may have at law or in equity in the event of the breach of any of the terms of this Agreement. The exercise or partial exercise of any right, power or remedy will neither


  
 21 













 
constitute the exclusive election thereof nor the waiver of any other right, power or remedy available to such Party. Without limiting the foregoing, the Parties hereto acknowledge and agree
irreparable harm may occur for which money damages would not be an adequate remedy in the event that any of the provisions of this Agreement were not performed in accordance with their specific terms or were otherwise breached. It is accordingly
agreed that the Parties shall be entitled to injunctive relief to address breaches of this Agreement and to enforce specifically the terms and provisions of this Agreement. 
  

	8.18	 No Waiver. 



Failure to insist upon strict compliance with any of the terms, covenants, or conditions hereof will not be deemed a waiver of such term,
covenant, or condition, nor will any waiver or relinquishment of, or failure to insist upon strict compliance with, any right, power or remedy power hereunder at any one or more times be deemed a waiver or relinquishment of such right, power or
remedy at any other time or times. 
  

	8.19	 No Presumption.  



The Parties acknowledge that any applicable law that would require interpretation of any claimed ambiguities in this Agreement against the
Party that drafted it has no application and is expressly waived. If any claim is made by a Party relating to any conflict, omission or ambiguity in the provisions of this Agreement, no presumption or burden of proof or persuasion will be implied
because this Agreement was prepared by or at the request of any Party or its counsel. 
  

	8.20	 Exculpation Among Investors; Independent Nature of Investors’ Obligations and Rights



 Each Investor agrees that no Investor nor the respective controlling persons, officers, directors, partners, agents, or
employees of any Investor shall be liable to any other Investor for any action heretofore or hereafter taken or omitted to be taken by any of them in connection with the purchase of the Series C Preferred Shares. No Investor is responsible in any
way for the performance or conduct of any other Investor in connection with the transactions contemplated hereby. Nothing contained herein or in any other Transaction Document, and no action taken by any Investor pursuant hereto or thereto, shall be

contemplated hereby. 
  

	8.21	 Third Party Beneficiaries. 



Each of the Indemnitees shall be a third party beneficiary of this Agreement with the full ability to enforce
Section 7 of this Agreement as if it were a Party hereto.

There is no material claim asserted or, to the Knowledge of the Warrantors, threatened by any Person regarding the lessor’s ownership of the property demised pursuant to each Lease. Each Lease is in compliance in all material respects with
applicable Laws, including with respect to the ownership and operation of property and conduct of business as now conducted by the applicable Group Company which is a party to such Lease. Each Group Company which is party to a Lease has accepted
possession of the property demised pursuant to the Lease and is in actual possession thereof and has not sublet, assigned or hypothecated its leasehold interest. No Group Company uses any real property in the conduct of its business except insofar
as it has secured a Lease with respect thereto. The leasehold interests under the Leases held by each Group Company are adequate for the conduct of the business of such Group Company as currently conducted. To the Knowledge of the Warrantors, there
exists no pending or , threatened condemnation, confiscation, eminent domain proceeding, dispute, claim, demand or similar proceeding with respect to, or which could materially and adversely affect, the continued use and enjoyment of such leasehold
interests. To the Knowledge of the Warrantors, there are no circumstances that would entitle any Governmental Authority or other Person to take possession or otherwise restrict use, possession or occupation of any property subject to any Leases. The
use and operation of the real properties subject to the Leases by the Group Companies is in compliance with all applicable Laws in all material respects, including, without limitation, all applicable building codes, environmental, zoning,
subdivision, and land use laws. None of the Group Companies has received notice from any Governmental Authority advising it of a violation (or an alleged violation) of any such laws or regulations.

	12.2	 IP Ownership. All Company Registered IP is owned by and registered or applied for solely in the name of
a Group Company, is valid and subsisting and has not been abandoned, and all necessary registration, maintenance and renewal fees with respect thereto and currently due have been satisfied. No Group Company or any of its employees, officers or
directors has taken any actions or failed to take any actions that would cause any Company IP to be invalid, unenforceable or not subsisting. No funding or facilities of a Governmental Authority or a university, college, other educational
institution or research center was used in the development of any material Company IP. No material Company IP is the subject of any Lien, license or other Contract granting rights therein to any other Person. No Group Company is or has been a member
or promoter of, or contributor to, any industry standards bodies, patent pooling organizations or similar organizations that could require or obligate a Group Company to grant or offer to any Person any license or right to any material Company IP.
No Company IP is subject to any proceeding or outstanding Governmental Order or settlement agreement or stipulation that (a) restricts in any manner the use, transfer or licensing thereof, or the making, using, sale, or offering for sale of any
Group Company’s products or services, by any Group Company, or (b) may affect the validity, use or enforceability of such Company IP. Each Key Holder has assigned and transferred to a Group Company any and all of his/her Intellectual
Property related to the Business. No Group Company has (i) transferred or assigned any material Company IP; (ii) authorized the joint ownership of, any material Company IP; or (iii) permitted the rights of any Group Company in any
material Company IP to lapse or enter the public domain. 


  

	12.3	 Infringement, Misappropriation and Claims. No Group Company has violated, infringed or misappropriated
in any material respect any Intellectual Property of any other Person nor has any Group Company received any written notice alleging any of the foregoing. To the Knowledge of the Warrantors, no Person has violated, infringed or misappropriated any
material Company IP of any Group Company, and no Group Company has given any written notice to any other Person alleging any of the foregoing. No Person has challenged the ownership or use of any material Company IP by a Group Company. No Group
Company has agreed to indemnify any Person for any infringement, violation or misappropriation of any Intellectual Property by such Person. 


  

	12.4	 Assignments and Prior IP. All material inventions and material
know-how conceived by employees of a Group Company related to the business of such Group Company are currently owned exclusively by a Group Company. All employees, contractors, agents and consultants of a
Group Company who are or were involved in the creation of any Intellectual Property for such Group Company have executed an assignment of inventions agreement that vests in a Group Company exclusive ownership of all right, title and interest in and
to such Intellectual Property, to the extent not already provided by Law. All employee inventors of Company IP have received reasonable reward and remuneration from a Group Company for his/her service inventions or service technology achievements in
accordance with the applicable PRC Laws. To the Knowledge of the Warrantors, it will not be necessary to utilize any Intellectual Property of any such Persons made prior to their employment by a Group Company, except for those that are exclusively
owned by a Group Company, and none of such Intellectual Property has been utilized by any Group Company. To the Knowledge of the Warrantors, none of the employees, consultants or independent

of any Group Company and all suppliers, customers, distributors, and other third parties having access to any material Company IP have executed and delivered to such Group Company an agreement requiring the protection of such Company IP. To the
extent that any Company IP has been developed or created independently or jointly by an independent contractor or other third party for any Group Company, or is incorporated into any products or services of any Group Company, such Group Company has
a written agreement with such independent contractor or third party and has thereby obtained ownership of, and is the exclusive owner of all such independent contractor’s or third party’s Intellectual Property in such work, material or
invention by operation of law or valid assignment. 


  

	12.7	 No Public Software. No Public Software forms part of any product or service provided by any Group
Company or was or is used in connection with the development of any product or service provided by any Group Company or is incorporated into, in whole or in part, or has been distributed with, in whole or in part, any product or service provided by
any Group Company. No Software included in any Company IP has been or is being distributed, in whole or in part, or was used, or is being used in conjunction with any Public Software in a manner which would require that such Software be disclosed or
