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 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

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. 



  
 18

with the substantive Law of Hong Kong and shall not apply any other substantive law. 


  

	 	(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 A+ 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 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. 
  

	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. 

  
 19 














	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.  



Each Investor acknowledges that it is not relying upon any person, firm or corporation, other than the Company and its officers and directors,
in making its investment or decision to invest in the Company. 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 A+ Preferred Shares. 
  

	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.

	 	(3)	 by the Investors 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 



  
 20 














	 	(4)	 by any Investor, severally but not jointly, or the Company if the Closing shall not have occurred on or before
September 30, 2015. For avoidance of doubt, if the Agreement is terminated by an Investor according to this Section 8.22 (a) (4), the Agreement shall remain valid and enforceable between the Company and any other
Investors who have not elected to terminate this Agreement. 


  

	 	(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 Investors 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 A+ 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 Investors; 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.

shall not use the name or brand of SEQUOIA or its Affiliate, claim itself as a partner of SEQUOIA or its Affiliate, make any similar representations. Without the written approval of SEQUOIA, the Group Companies, their shareholders (excluding

	11.	 Title; Properties. 



 

	11.1	 Title; Personal Property. Each Group Company has good and valid title to all of its respective
assets, whether tangible or intangible (including those reflected in the Financial Information, together with all assets acquired thereby since the incorporation of 



  
 7 














	 	
the Company, but excluding those that have been disposed of since the incorporation of the Company), in each case free and clear of all Liens, other than Permitted Liens. The foregoing assets
collectively represent in all material respects all assets (including all rights and properties) necessary for the conduct of the business of each Group Company as presently conducted. Except for leased or licensed assets, no Person other than a
Group Company owns any interest in any such assets. All leases of real or personal property to which a Group Company is a party are fully effective and afford the Group Company valid leasehold possession of the real or personal property that is the
subject of the lease. All machinery, vehicles, equipment and other tangible personal property owned or leased by a Group Company are (a) in good condition and repair in all material respects (reasonable wear and tear excepted) and (b) not

any Consent required from the owner of the property demised pursuant to the Lease if the lessor is not such owner. 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. 


  

	12.	 Intellectual Property. 



 

	12.1	 Company IP. Each Group Company owns or otherwise has sufficient rights (including but not limited to the

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 Owned 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 Owned IP. No material Company Owned 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 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
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

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




  
 9 














	 	
interest in 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 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 contractors, currently or previously employed or otherwise engaged by any Group Company, (a) is in violation of any current or prior confidentiality, non-competition or non-solicitation obligations to such Group Company or to any other Persons, including former employers, or (b) is obligated under any Contract, or subject to any Governmental Order, that would interfere with
the use of his or her best efforts to promote the interests of the Group Companies or that would conflict with the business of such Group Company as presently conducted.

accurate list of the Licenses. The Group Companies have paid all license and royalty fees required to be paid under the Licenses. 


  

	12.6	 Protection of IP. Each Group Company has taken reasonable and appropriate steps to protect, maintain and
safeguard material Company IP and made all applicable filings, registrations and payments of fees in connection with the foregoing. Without limiting the foregoing, all current and former officers, employees, consultants and independent contractors
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 Owned 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
