its business as proposed, would violate any Proprietary Assets of any other person or entity, nor, to the best knowledge of the Group Companies and the Seller Parties, is there any reasonable basis therefor. To the best knowledge of each Group
Company and each Seller Party, none of the Seller Parties nor any of the current or former officers, employees or consultants of any Group Company (at the time of their employment or engagement by a Group Company) has been or is obligated under any
contract (including licenses, covenants or commitments of any nature) or other agreement, or subject to any judgment, decree or order of any court or administrative agency, that would interfere with the use of his, her or its best efforts to promote
the interests of such Group Company or that would conflict with the business of such Group Company as proposed to be conducted or that would prevent such officers, employees or consultants from assigning to such Group Company inventions conceived or
reduced to practice in connection with services rendered to such Group Company. Neither the execution nor delivery of any of the Agreements, nor the carrying on of the business of any Group Company by its employees, nor the conduct of the business
of any Group Company as proposed, will, to the best knowledge of each Group Company and Seller Party, conflict with or result in a breach of the 

  

 6 

 
terms, conditions or provisions of, or constitute a default under, any contract, covenant or instrument under which any of such employees is now obligated.

outside the scope of their employment by the relevant Group Company. No government funding, facilities of any educational institution or research center, or funding from third parties has been used in the development of any Proprietary Assets of any
Group Company.

specified periods, or otherwise, (iv) not in the ordinary course of business, (v) transferring or licensing any Proprietary Assets to or from any Group Company (other than licenses granted in the ordinary course of business or licenses
from commercially readily available “off the shelf” computer software) or (vi) an agreement the termination of which would be reasonably likely to have a Material Adverse Effect. 
 3.10. Litigation. There is no action, suit, proceeding, claim, arbitration or investigation (“Action”) pending (or, to the best
knowledge of each Group Company and Seller Party, currently threatened in writing) against any of the Group Companies, any Group Company’s activities, properties or assets or, to the best of each Group Company’s and Seller Party’s
knowledge, against any officer, director or employee of each Group Company in connection with such officer’s, director’s or employee’s relationship with, or actions taken on behalf of any Group Company, or otherwise. To the best
knowledge of each Group Company and Seller Party, there is no factual or legal basis for any such Action that is likely to result, individually or in the aggregate, in any material adverse change in the business, properties, assets, financial
condition, affairs or prospects of any Group Company. By way of example, but not by way of limitation, there are no Actions pending against any of the Group Companies or, to the best knowledge of each Group Company and Seller Party, threatened

Documents or any Group Company Contract, or, to the best knowledge of each Group Company and Seller Party, a violation of any statutes, laws, regulations or orders, or an event which results in the creation of any material lien, charge or
encumbrance upon any asset of any Group Company.

 Re: Management Rights 
 Gentlemen: 
 This letter will confirm our agreement that
pursuant to and effective as of your purchase of 350,000 Series A Preferred Shares of Thinkplus Investments Limited (the “Company”), DCM IV, L.P. and DCM Affiliates Fund IV, L.P. (collectively, the “Investor”) shall be entitled
to the following contractual management rights, in addition to any rights to non-public financial information, inspection rights and other rights specifically provided to all investors in the current financing: 
 1. The Company shall provide to you at your written request, within 30 days of the end of each calendar year, a list of all holders of equity interests
and rights to acquire equity interests in the Company as of the end of such year, and the type and amount of such securities held by each such holder. 
 2. The Investor shall be entitled to consult with and advise management of the Company on significant business issues, including management’s proposed annual operating plans, and management will meet with you
regularly during each year at the Company’s facilities at mutually agreeable times for such consultation and advice and to review progress in achieving said plans. 
 3. The Investor may examine the books and records of the Company and inspect its facilities and may request information at reasonable times and intervals concerning the general status of the Company’s financial
condition and operations, provided that access to highly confidential proprietary information and facilities need not be provided. 
 4. If
the Investor is not represented on the Company’s Board of Directors, the Company shall give a representative of the Investor copies of all notices, minutes, consents and other material that the Company provides to its directors, except that the
representative may be excluded from access to any material or meeting or portion thereof if the Company believes, upon advice of counsel, that such exclusion is reasonably necessary to preserve the attorney-client privilege, to protect highly
confidential proprietary information or for other similar reasons. Upon reasonable notice and at a scheduled meeting of the Board or such other time, if any, as the Board may determine in its sole discretion, such representative may address the
Board of Directors with respect to the Investor’s concerns regarding significant business issues facing the Company. 

 The Investor agrees, and any representative of the Investor will agree, to hold in confidence and trust
and not use or disclose any confidential information provided to or learned by it in connection with its rights under this letter. 
 The
rights described herein shall terminate and be of no further force or effect upon (a) the consummation of the sale of the Company’s securities pursuant to a registration statement filed by the Company under the Securities Act of 1933, as
amended, in connection with a firm-commitment underwritten offering of its securities to the public or (b) the consummation of a merger or consolidation of the Company that is effected (i) for independent business reasons unrelated to
extinguishing such rights and (ii) for purposes other than (A) the reincorporation of the Company in a different state or (B) the formation of a holding company that will be owned exclusively by the Company’s stockholders and
will hold all of the outstanding shares of capital stock of the Company’s successor. The confidentiality provisions hereof will survive any such termination.

 PFIC Annual Information Statement 
  

					
	(1)	 	          
	  	 This questionnaire applies to the taxable year of [Company] “Company” beginning on January 1, 20    ,
and ending on
 December 31, 20    .

  

					
	(2) 	 	          
	  	PLEASE CHECK HERE IF 75% OR MORE OF THE
COMPANY’S GROSS INCOME CONSTITUTES PASSIVE INCOME. 

 Passive income: For purposes of this test, passive income includes: 
  

	 	•	 	 Dividends, interests, royalties, rents and annuities, excluding, however, rents and royalties which are received from an unrelated party in connection with
the active conduct of a trade or business. 

  

	 	•	 	 Net gains from the sale or exchange of property— 

  

	 	•	 	 which gives rise to dividends, interest, rents or annuities (excluding, however, property used in the conduct of a banking, finance or similar business, or
in the conduct of an insurance business); 

  

	 	•	 	 which is an interest in a trust, partnership, or REMIC; or 

  

	 	•	 	 which does not give rise to income. 

  

	 	•	 	 Net gains from transactions in commodities. 

  

	 	•	 	 Net foreign currency gains. 

  

	 	•	 	 Any income equivalent to interest. 

 Look-through rule: if the Company owns, directly or indirectly, 25% of the stock by value of another corporation, the Company must take into account its proportionate share of the income received by such other corporation.

  

					
	(3) 	 	          
	  	PLEASE CHECK HERE IF THE AVERAGE FAIR MARKET VALUE
DURING THE TAXABLE YEAR OF PASSIVE ASSETS HELD BY THE COMPANY EQUALS
50% OR MORE OF THE AVERAGE FAIR MARKET VALUE OF ALL OF THE
COMPANY’S ASSETS.

 Note: This test is applied on a gross basis; no liabilities are taken into account.

 Passive Assets: For purposes of this test, “passive assets” are those assets which generate (or are reasonably expected to
generate) passive income (as defined above). Assets which generate partly passive and partly non-passive income are considered passive assets to the extent of the relative proportion of passive income (compared to non-passive income) generated in a
particular taxable year by such assets. Please note the following: 
  

	 	•	 	 A trade or service receivable is non-passive if it results from sales or services provided in the ordinary course of business. 

  

	 	•	 	 Intangible assets that produce identifiable items of income, such as patents or licenses, are characterized in terms of the type of income produced.

	 	•	 	 Goodwill and going concern value must be identified to a specific income producing activity and are characterized in accordance with the nature of that activity.

  

	 	•	 	 Cash and other assets easily convertible into cash are passive assets, even when used as working capital. 

  

	 	•	 	 Stock and securities (including tax-exempt securities) are passive assets, unless held by a dealer as inventory. 

 Average value: For purposes of this test, “average fair market value” equals the average quarterly fair market value of the assets for
the relevant taxable year. 
 Look-through rule: if the Company owns, directly or indirectly, 25% of the stock by value of another
corporation, the Company must take into account its proportionate share of the passive assets of such other corporation. 
  

					
	(4) 	 	          
	  	PLEASE CHECK HERE IF (A) MORE THAN 50% OF THE
COMPANY’S STOCK (BY VOTING POWER OR BY VALUE) IS OWNED BY
FIVE OR FEWER U.S. PERSONS OR ENTITIES AND (B) THE AVERAGE AGGREGATE
ADJUSTED TAX BASES (AS DETERMINED UNDER U.S. TAX PRINCIPLES) DURING THE TAXABLE
YEAR OF THE PASSIVE ASSETS HELD BY THE COMPANY EQUALS 50% OR MORE
OF THE AVERAGE AGGREGATE ADJUSTED TAX BASES OF ALL OF THE
COMPANY’S ASSETS.

 Average value: For purposes of this test, “average aggregate adjusted tax bases”
equals the average quarterly aggregate adjusted tax bases of the assets for the relevant taxable year. 
 Look-through rule: if the
Company owns, directly or indirectly, 25% of the stock by value of another corporation, the Company must take into account its proportionate share of the passive assets of such other corporation 
  

					
	(5) 	 	          
	  	[INVESTOR] HAS THE FOLLOWING PRO-RATA SHARE OF THE
ORDINARY EARNINGS AND NET CAPITAL GAIN OF THE COMPANY AS DETERMINED
UNDER U.S. INCOME TAX PRINCIPLES FOR THE TAXABLE YEAR OF THE
COMPANY:
			
		 		  	Ordinary Earnings:                      (as determined under U.S. income tax
principles)
			
		 		  	Net Capital Gain:                      (as determined under U.S income tax principles)

			
		 		  	Pro Rata Share: For purposes of the foregoing, the shareholder’s pro rata share equals the amount that would have been distributed with respect to the shareholder’s stock if, on
each day during the taxable year of the Company, the Company had distributed to each shareholder its pro rata share of that day’s ratable share (determined by allocating to each day of the year, an equal amount of the Company’s aggregate
ordinary earnings and aggregate net capital gain for such year) of the Company’s ordinary earnings and net capital gain for such year. Determination of a shareholder’s pro rata share will require reference to the Company’s charter,
certificate of incorporation, articles of association or other comparable governing document.

					
	(6) 	 		  	The amount of cash and fair market value of other property distributed or deemed distributed by Company to [Investor] during the taxable year specified in paragraph 1. is as
follows:

 Cash:
                     
 Fair
Market Value of Property:                      
  

					
	(7) 	 		  	Company will permit [Investor] to inspect and copy Company’s permanent books of account, records, and such other documents as may be maintained by Company that are necessary to establish
that PFIC ordinary earnings and net capital gain, as provided in Section 1293(e) of the U.S. Internal Revenue Code of 1986, as amended (or any successor provision thereto), are computed in accordance with U.S. income tax
principles.

 The foregoing representations are true and accurate as of the date hereof. If in any respect
such representations shall cease to be true and accurate, the undersigned shall give immediate notice of such fact to [Investor].
