	6.14	 Performance Commitment. 



 

	 	(a)	 Each of the Parties hereby acknowledges, confirms and agrees that, the
pre-money valuation of the Company on a fully-diluted and as-converted basis (the “Pre-Money Valuation”) applied
for the subscription of the Series B Preferred Shares contemplated hereunder at the Closing, which is RMB1,600,000,000 in equivalent US Dollars (the “Initial Pre-Money Valuation”), is based on
the following performance projections of the Group Companies: (i) the audited sales revenue of the Group Companies’ primary business on a consolidated basis of the fiscal year of 2017 of the Company (commencing from January 1, 2017
till December 31, 2017) prepared in accordance with the PRC GAAP and audited and certified by an accounting firm acceptable to the Investor (the “Qualified Auditor”, and such audited sales revenue, the “Sales Revenue of
2017”) would be no less than RMB160,000,000 (the “Qualified Sales Revenue”), and (ii) the net loss of the Group Companies on a consolidated basis of the fiscal year of 2017 of the Company (commencing from
January 1, 2017 till December 31, 2017) prepared in accordance with the PRC GAAP and audited and certified by the Qualified Auditor (the “Net Loss of 2017”) would be no more than RMB50,000,000 (the “Qualified Net
Loss”). The Warrantors shall cause the Qualified Auditor to provide the Sales Revenue of 2017 and the Net Loss of 2017 in reasonable details to the Investor no later than March 31, 2018. For the avoidance of doubt, any reasonable fees,
costs and expenses incurred by the Company in connection with the transactions as contemplated under any employee share incentive plan of the Company (including but not limited to the Option Plan) shall not be calculated as the Net Loss of 2017.



  

	 	(b)	 If the Sales Revenue of 2017 is less than the Qualified Sales Revenue (such Sales Revenue of 2017, the
“Non-Qualified Sales Revenue”), the Pre-Money Valuation shall be immediately adjusted to according to the following formula: 



the adjusted Pre-Money Valuation = ten (10) times of the
Non-Qualified Sales Revenue. 
 For the purpose of this Section 6.14, the
decrease from the Initial Pre-Money Valuation to the above adjusted Pre-Money Valuation, the “Sales Revenue Adjustment”. 

 

	 	(c)	 If the Net Loss of 2017 is more than the Qualified Net Loss (such Net Loss of 2017, the “Non-Qualified Net Loss”, and the difference between the Non-Qualified Net Loss and the Qualified Net Loss, the “Net Loss Difference”), the holders of
at least fifty percent (50%) of the then issued and outstanding Series B Preferred Shares (including Sequoia and LYFE as long as they hold any Series B Preferred Share) is entitled to request the Pre-Money
Valuation to be immediately adjusted according to the following formula by serving a written notice upon the Company: 



the adjusted Pre-Money Valuation = the Initial Pre-Money
Valuation – 10 × the Net Loss Difference. 

  
 11 













 For the purpose of this Section 6.14, the decrease from the
Initial Pre-Money Valuation to the above adjusted Pre-Money Valuation, the “Net Loss Adjustment”. 

 

	 	(d)	 For avoidance of doubt, the Sales Revenue Adjustment and the Net Loss Adjustment set forth in
Section 6.14(b) and Section 6.14(c) above are cumulative with each other, and not in lieu thereof. Therefore, in the event of occurrence of the Sales Revenue Adjustment and/or the Net Loss
Adjustment, the Pre-Money Valuation shall be immediately adjusted according to the following formula: 



the adjusted Pre-Money Valuation (the “Adjusted
Pre-Money Valuation”) = the Initial Pre-Money Valuation – the Sales Revenue Adjustment (if any) – the Net Loss Adjustment (if any). 

 

	 	(e)	 In the event of occurrence of the Sales Revenue Adjustment and/or the Net Loss Adjustment, the Investor is
entitled to request the Company to issue additional new Series B Preferred Shares at nil consideration such that after the new issuance the total number of Series B Preferred Shares held by the Investor is adjusted according to the following
formula: 


 total number of Series B Preferred Shares held by the Investor immediately after the adjustment = total number
of Series B Preferred Shares held by the Investor immediately prior to the adjustment × the Pre-Money Valuation / the Adjusted Pre-Money Valuation, 

and further, the Series B Preferred Issue Price with respect to the Investor as defined in the Amended M&A shall also be adjusted and
amended according to the following formula: 
 Series B Preferred Issue Price immediately after such adjustment = Series B Preferred Issue
Price (as defined in the Amended M&A) / the Pre-Money Valuation × the Adjusted Pre-Money Valuation. 

 

	 	(f)	 If (i) the Sales Revenue of 2017 is no less than RMB190,000,000, and (ii) the ratio of the Net Loss
of 2017 to the Sales Revenue of 2017 is no more than the ratio of the Qualified Net Loss to the Qualified Sales Revenue, each of the Parties hereby agrees that, additional Ordinary Shares shall be reserved for issuance under the Option Plan and
additional Ordinary Shares shall be issued to the Holding Entity at nil consideration, which results that (i) the shareholding percentage of the total Ordinary Shares reserved for issuance under the Option Plan in the Company on a fully-diluted
and as-converted basis shall be increased by 0.5% immediately after the foregoing reservation and issuance; (ii) the shareholding percentage of the Holding Entity then in the Company on a fully-diluted
and as-converted basis shall remain the same as that immediately prior to the foregoing reservation and issuance, and (iii) the shareholding percentage of the Preferred Shareholders (other than the
Holding Entity) then in the Company on a fully-diluted and as-converted basis shall be diluted on a pro rata basis as a result of the foregoing reservation and issuance.

investigation, defense and resolution of any Breach paid, suffered, sustained or incurred by the Indemnitees (each, an “Indemnifiable Loss”), resulting from, or arising out of, or due to, any Breach. 

  
 13 














	7.2	 Notwithstanding the foregoing, the Warrantors shall, jointly and severally, indemnify and keep indemnified the
Indemnitees and hold them harmless against any and all Indemnifiable Losses resulting from, or arising out of, or due to, any claim for tax which has been made or may hereafter be made against the Domestic Companies and any other Group Company
wholly or partly in respect of or in consequence of any event occurring or any income, profits or gains earned, accrued or received by the Domestic Companies and any Group Company on or before the Closing and any reasonable costs, fees or expenses
incurred and other liabilities which the Domestic Companies and any Group Company may properly incur in connection with the investigation, assessment or the contesting of any claim, the settlement of any claim for tax, any legal proceedings in which
the Domestic Companies claims in respect of the claim for tax and in which an arbitration award or judgment is given for the Domestic Companies or Group Company and the enforcement of any such arbitration award or judgment, provided, however,
that the Key Holders shall be under no liability in respect of taxation: 


  

	 	(a)	 that is promptly cured without recourse to cash or other assets of any Group Company; 



 

	 	(b)	 to the extent that provision, reserve or allowance has been made for such tax in the audited consolidated
Financial Statements of the Company; 


  

	 	(c)	 if it has arisen in and relates to the ordinary course of business of the Domestic Companies since the
Statement Date; 


  

	 	(d)	 to the extent that the liability arises as a result only of a provision or reserve in respect of the liability
made in the Financial Statements being insufficient by reason of any increase in rates of tax announced after the Closing with retrospective effect; or 


  

	 	(e)	 to the extent that the liability arises as a result of legislation which comes into force after the Closing and
which is retrospective in effect. 


 The survival period for any indemnity obligation relating to claims for tax matters
arising under this Section 7.2 shall be the applicable statute of limitations for tax claims. 
  

	7.3	 Subject to the second paragraph of Section 7.1, in the event that an Indemnitee
suffers an Indemnifiable Loss as provided in Section 7.1 or Section7.2 and the Group Companies are either unwilling or unable to fulfill their obligations under Section 7.1 or
Section 7.2 to indemnify the Indemnitees for the full amount of such Indemnifiable Loss within sixty (60) days of receipt of written notice thereof from the Investor (the “Grace Period”), then the Key
Holders, shall indemnify the Indemnitees such that the Indemnitees shall receive the full amount of such Indemnifiable Loss, provided that, to the extent such Indemnitees have recovered any 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 Investor or the director appointed by the Investor. 



  
 14 














	7.4	 If the 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 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. 


  

	7.5	 Notwithstanding any other provision of this Agreement or the other Transaction Documents, the maximum aggregate
liability of the Group Companies for indemnification to any Indemnitee under this Section 7 shall be limited to the aggregate Purchase Price paid by the Indemnitee or its Affiliates plus all dividends accrued and unpaid with respect to such
shares held by the Indemnitee or its Affiliates) (the “Group Indemnification Cap”); 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 the Group Companies (the “Holder Indemnification Cap”).

such party (the “Disclosing Party”) shall provide the other parties with prompt written notice of that fact and shall consult with the other parties regarding such disclosure. At the request of another party, the Disclosing Party
shall, to the extent reasonably possible and with the cooperation and reasonable efforts of the other parties, seek a protective order, confidential treatment or other appropriate remedy. In any event, the Disclosing Party shall furnish only that
portion of the information that is legally required and shall exercise reasonable efforts to obtain reliable assurance that confidential treatment will be accorded such information. 



 

	 	(d)	 Other Exceptions. Notwithstanding any other provision of this Section 8.2, the
confidentiality obligations of the Parties shall not apply to: (i) information which a restricted Party learns from a third party having the right to make the disclosure, provided the restricted Party complies with any restrictions imposed by
the third party; (ii) information which is rightfully in the restricted Party’s possession prior to the time of disclosure by the protected Party and not acquired by the restricted Party under a confidentiality obligation; or
(iii) information which enters the public domain without breach of confidentiality by the restricted Party.

party under this Agreement, shall impair any such right, power or remedy of such non-breaching or non-defaulting party nor shall it be construed to be a waiver of any
such breach or default, or an acquiescence therein, or of or in any similar breach or default thereafter occurring; nor 

  
 18 













 
shall any waiver of any single breach or default be deemed a waiver of any other breach or default theretofore or thereafter occurring. Any waiver, permit, consent or approval of any kind or
character on the part of any party of any breach or default under this Agreement, or any waiver on the part of any party of any provisions or conditions of this Agreement, must be in writing and shall be effective only to the extent specifically set
forth in such writing. All remedies, either under this Agreement or by law or otherwise afforded to any party, shall be cumulative and not alternative. 
  

	8.14	 Entire Agreement. 



This Agreement (including the Schedules and Exhibits hereto) and the other Transaction Documents constitute the full and entire understanding
and agreement between the parties with respect to the subject matter hereof, and any other written or oral agreement relating to the subject matter hereof existing between the parties are expressly canceled. 

 

	8.15	 Dispute Resolution. 



 

	 	(a)	 Any dispute, controversy or claim arising out of or relating to this Agreement, or the interpretation, breach,
termination or validity hereof, shall first be subject to resolution through consultation of the parties to such dispute, controversy or claim. Such consultation shall begin within seven (7) days after one Party hereto has delivered to the
other Parties involved a written request for such consultation. If within thirty (30) days following the commencement of such consultation the dispute cannot be resolved, the dispute shall be submitted to arbitration upon the request of any
Party with notice to the other Parties. 


  

	 	(b)	 The arbitration shall be conducted in Hong Kong under the auspices of the Hong Kong International Arbitration
Centre (the “HKIAC”). There shall be three arbitrators. The complainant and the respondent to such dispute shall each select one arbitrator within thirty (30) days after giving or receiving the demand for arbitration. Such
arbitrators shall be freely selected, and the Parties shall not be limited in their selection to any prescribed list. The Chairman of the HKIAC shall select the third arbitrator. If either party to the arbitration does not appoint an arbitrator who
has consented to participate within thirty (30) days after selection of the first arbitrator, the relevant appointment shall be made by the Chairman of the HKIAC. 



 

	 	(c)	 The arbitration proceedings shall be conducted in English. The arbitration tribunal shall apply the Arbitration
Rules of the HKIAC in effect at the time of the arbitration. However, if such rules are in conflict with the provisions of this Section 8.15, including the provisions concerning the appointment of arbitrators, the
provisions of this Section 8.15 shall prevail. 


  

	 	(d)	 The arbitrators shall decide any dispute submitted by the parties to the arbitration strictly in accordance
with the substantive Law of Hong Kong and shall not apply any other substantive law. 



  
 19 














	 	(e)	 Each Party hereto shall cooperate with any party to the dispute in making full disclosure of and providing
complete access to all information and documents requested by such party in connection with such arbitration proceedings, subject only to any confidentiality obligations binding on the Party receiving the request. 



 

	 	(f)	 The award of the arbitration tribunal shall be final and binding upon the disputing parties, and any party to
the dispute may apply to a court of competent jurisdiction for enforcement of such award. 


  

	 	(g)	 Any party to the dispute shall be entitled to seek preliminary injunctive relief, if possible, from any court
of competent jurisdiction pending the constitution of the arbitral tribunal. 


  

	8.16	 No Commitment for Additional Financing. 



The Company acknowledges and agrees that no Investor has made any representation, undertaking, commitment or agreement to provide or assist the
Company in obtaining any financing, investment or other assistance, other than the purchase of the Series B Preferred Shares as set forth herein and subject to the conditions set forth herein. In addition, the Company acknowledges and agrees that
(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 the 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. The 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. 
  

	8.17	 Rights Cumulative. 



Each and all of the various rights, powers and remedies of a Party will be considered to be cumulative with and in addition to any other
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 constitute the exclusive election
thereof nor the waiver of any other right, power or remedy available to such Party. 
  

	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. 

  
 20 














	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	 [Reserved]. 


  

	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.  
  

	8.22	 Termination of Agreement. 



 

	 	(a)	 This Agreement may be terminated before the Closing as follows: 



 

	 	(1)	 by mutual written consent of the Company and the Investor as evidenced in writing signed by each of the Company
and the Investor; 


  

	 	(2)	 by the Investor in the event of any material breach or violation of any representation or warranty, covenant or
agreement contained herein or in any of the other Transaction Documents by any Warrantor; 


  

	 	(3)	 by the Investor if any event, circumstance or change shall have occurred that, individually or in the aggregate
with one or more other events, circumstances or changes, have had or reasonably could be expected to have a Material Adverse Effect on the Group Companies; or 



 

	 	(4)	 by the Investor or the Company if the Closing shall not have occurred on or before June 30th, 2017. 


  

	 	(b)	 Effect of Termination. The date of termination of this Agreement pursuant to
Section 8.22(a) hereof shall be referred to as “Termination Date”. In the event of termination by the Company and/or the Investor pursuant to Section 8.22(a) hereof, written notice
thereof shall forthwith be given to the other Party and this Agreement shall terminate, and the purchase of the Series B Preferred Shares hereunder shall be abandoned and rescinded, without further action by the Parties hereto. Each of the Parties
shall be relieved of their duties and obligations arising under this Agreement after the date of such termination and such termination shall be without liability to the Warrantors or the Investor; provided that no such termination shall
relieve any party hereto from liability for any breach of this Agreement. The provisions of this Section 8.22, Section 7, Section 8.2,
Section 8.4, Section 8.9, and Section 8.15, hereof shall survive any termination of this Agreement.

Company Owned IP. No Company Owned 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 Owned IP. Each Key Holder has assigned and transferred to a Group Company any and

to such Intellectual Property, to the extent not already provided by Law. All employee inventors of Company Owned 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

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
