	 	“11.	DRAG ALONG RIGHTS 

(a) Subject to the written approval from (i) Holder(s) of not less than 51% of all outstanding Series A Preferred Shares, 51% of all
outstanding Series B Preferred Shares and 51% of all outstanding Series C Preferred Shares, each voting as a separate class , in the event of the Company receiving a bona fide offer to purchase all or substantially all of the assets of the Group or

Company or the party to such Drag Along Transaction. Costs incurred by or on behalf of such Investor for its sole benefit will not be considered costs of the transaction hereunder. 

In addition, any amendments to or waivers of the drag-along provisions must require each Investor’s consent.

“Waiver. The Company acknowledges that each Preferred Shareholder will likely have, from time to time, information that may be
of interest to the Company or any of its subsidiaries (“Information”) regarding a wide variety of matters including, by way of example only, (1) an Preferred Shareholder’s technologies, plans and services, and plans and
strategies relating thereto, (2) current and future investments the Preferred Shareholder has made, may make, may consider or may become aware of with respect to other companies and other technologies, products and services, including, without
limitation, technologies, products and services that may be competitive with those of the Company or its subsidiaries, and (3) developments with respect to the technologies, products and services, and plans and strategies relating thereto, of
other companies, including, without limitation, companies that may be competitive with the Company or any of its subsidiaries. The Company recognizes that a portion of such Information may be of interest to the Company or any of its subsidiaries.
Such Information may or may not be known by the Preferred Directors or the Observers. The Company, as a material part of the consideration for entering into the Series C Preferred Shares Subscription Agreement and this Agreement, agrees that neither
the Observer nor the Preferred Directors shall have any duty to disclose any Information to the Company or its subsidiaries, or permit the Company or any of its subsidiaries to participate in any projects or investments based on any Information, or
to otherwise take advantage of any opportunity that may be of interest to the Company or any of its subsidiaries if it were aware of such Information, and hereby waives, to the extent permitted by law, any claim based on the corporate opportunity
doctrine or otherwise that could limit the Investor’s ability to pursue opportunities based on such Information or that would require any Preferred Shareholder, any Preferred Director or any Observer to disclose any such Information to the
Company or any of its subsidiaries or offer any opportunity relating thereto to the Company or any of its subsidiaries. The Existing Shareholders, the Founders and the Company hereby irrevocably agree that the Preferred Directors and Observers are
nominees of the Preferred Shareholder who appoints him and that the Preferred Directors and Observers shall be entitled to, and the Preferred Shareholder who nominates him can require him to, report all matters concerning the Company and its
Subsidiaries, including but not limited to, matters discussed at any meeting of the Board, and that the Preferred Directors and Observers may take advice and obtain instructions from his/her nominating Preferred Shareholder; provided that nothing
herein shall relieve the nominating Preferred Shareholder of its confidentiality obligations herein and in the Series C Preferred Shares Subscription Agreement.” 

	 	1.7	A new Section 20(p) shall be added to the Shareholders’ Agreement to be read in its entirety as follows: 

“20 (p) Conflict with Articles. 
 In the event of any conflict or inconsistency between the provisions of this Agreement and the provisions of the Articles or other constitutional documents, the terms of this Agreement shall prevail as
between the shareholders of the Company only. The Preferred Shareholders and the holders of the Common Stock of the Company shall, notwithstanding the conflict or inconsistency, act so as to effect the intent of this Agreement to the greatest extent
possible under the circumstances and shall promptly amend the conflicting constitutional documents to conform to this Agreement to the greatest extent possible.” 
  

	 	1.8	The following exhibit to the Shareholders’ Agreement shall be deleted in their entirety and substituted by the exhibits as attached hereto:

 Exhibit B - List of Preferred Shareholders 

Exhibit C - Shareholdings as of the date of this Agreement 

 

	2.	The amendments contained in this Amendment No. 1 to SHA shall take effect from the Effective Date. Save as expressly amended pursuant to this Amendment No. 1
to SHA, all terms and conditions of the Shareholders Agreement shall remain unchanged and shall continue in full force and effect. 

  

	3.	The following provisions in the Agreement, namely, “Notice” (Section 21(d)) “Counterparts” (Section 21(m)) and “Governing Law” (Section
21(k)) shall apply, mutatis mutandis, to this Amendment No. 1 to SHA.

	2.	REGISTRATION RIGHTS 

  

	 	2.1	Demand Registration Rights 

  

	 	(a)	Subject to the limitations set forth in this Section 2.1, if the Company receives a written request from a Preferred Shareholder (the “Demand
Investor”) specifying the approximate number of Registrable Securities requested to be registered and the anticipated per share price range for such offering, requesting the Company file a registration statement under the Securities Act
covering the registration of all or a portion of Registrable Securities then outstanding with an aggregate public offering price of at least US$2,000,000, then the Company shall, as soon as practicable, and in any event within 90 days of receipt of
such request, file such registration and permit or facilitate the sale and distribution of all or such portion of the Registrable Securities as are specified in such request. All registrations requested pursuant to this Section 2.1 are
referred to herein as “Demand Registrations.” Within ten (10) days after receipt of any such request, the Company shall give written notice of such requested registration to all other holders of Registrable Securities and shall
include as part of such Demand Registration all Registrable Securities with respect to which the Company has received written requests for inclusion therein within fourteen (14) days after the receipt of the Company’s notice.

  

	 	(b)	The Company shall use commercially reasonable efforts to cause such registration statement to be declared effective by the SEC as soon as practicable.

  

	 	(c)	If the Demand Investor intends to distribute the Registrable Securities covered by their request by means of an underwriting, they shall so advise the Company as a part
of their request made pursuant to this Section 2.1. The underwriter shall be selected by the Demand Investor and shall be reasonably acceptable to the Company. In such event, the right of a Preferred Shareholder to include securities in
such registration pursuant to Section 2.1(a) shall be conditioned upon such Preferred Shareholder’s participation in such underwriting and the inclusion of its Registrable Securities in the underwriting to the extent provided herein
and the Demand Investor (together with the Company and other Holders proposing to distribute securities through such underwriting (if any)) enter into an underwriting agreement in customary form with the underwriter(s) selected for such underwriting
by the Demand Investor. 

  
 5 

	 	(d)	If a Demand Registration is an underwritten offering and the managing underwriters advise the Company in writing that in their opinion the number of Registrable
Securities requested to be included in such offering exceeds the number of Registrable Securities which can be sold therein without adversely affecting the marketability of the offering and within a price range acceptable to the holders of not less
than two-thirds (2/3) of the Registrable Securities initially requesting registration, the Company shall include in such registration the number of Registrable Securities requested to be included which in the opinion of such underwriters can be
sold without adversely affecting the marketability of the offering, pro rata among the respective holders thereof on the basis of the amount of the Registrable Securities owned by each such holder; provided that any Registrable Securities issued or
issuable upon conversion of the Preferred Shares shall be included, pro rata as amongst the holders thereof, in priority to any other Registrable Securities. Any Registrable Securities excluded or withdrawn from such underwriting shall be withdrawn
from the registration. 

  

	 	(e)	The Company shall not be obligated to effect, or to take any action to effect, any registration pursuant to this Section 2.1 demanded by a Demand Investor:

  

	 	(i)	prior to the earlier of (A) December 31, 2014, or (B) one hundred eighty (180) days following the effective date of the registration statement filed
in connection with the Company’s Qualified IPO; 

  

	 	(ii)	in any particular jurisdiction in which the Company would be required to execute a general consent to service of process in effecting such registration, unless the
Company is already subject to service in such jurisdiction and except as may be required by the Securities Act; 

  

	 	(iii)	after the Company has effected three (3) registrations pursuant to this Section 2.1 demanded by the same Demand Investor, and such registrations have
been declared or ordered effective; 

  

	 	(iv)	during the period starting with the date sixty (60) days prior to the Company’s good faith estimate of the date of the filing of, and ending on a date one
hundred eighty (180) days following the effective date of, a Company-initiated registration, provided that the Company is actively employing in good faith commercially reasonable efforts to cause such registration statement to become effective;

  

	 	(v)	if the Demand Investor proposes to dispose of Registrable Securities that may be registered as soon as practicable on Form F-3 pursuant to Section 2.3
hereof; or 

  
 6 

	 	(vi)	if the Company shall furnish to the Demand Investor a certificate signed by the Company’s Chief Executive Officer or Chairman of the Board stating that in the good
faith judgment of the Board of Directors of the Company, it would be seriously detrimental to the Company and its shareholders for such registration statement to be filed at such time, in which event the Company shall have the right to defer taking
action with respect to such filing for a period of not more than ninety (90) days after receipt of the request of the Demand Investor; provided, however, that such right to delay a request shall be exercised by the Company not
more than once in any twelve (12) month period in relation to the same Demand Investor; provided, further, that the Company shall not register any securities for the account of itself or any other shareholder during such ninety
(90) day period, other than a registration relating to (i) the sale of securities to officers, directors and employees of, or consultants to, any Group Company pursuant to share grants, option plans, purchase plans or other employee share
incentive programs or arrangements, (ii) a reclassification of securities, corporate reorganization or other transaction under Rule 145 of the Securities Act (or such applicable securities laws in the relevant jurisdiction), (iii) a
registration on any form that does not include substantially the same information as would be required to be included in a registration statement covering the sale of the Registrable Securities, or (iv) a registration in which the only Ordinary
Shares being registered are Ordinary Shares issuable upon conversion of debt securities that are also being registered (an “Exempt Registration”). 

 

	 	2.2	Piggyback Registration Rights 

  

	 	(a)	If (without any obligation to do so) the Company proposes to register (including for this purpose a registration effected by the Company for shareholders other than the
Preferred Shareholders) any of its shares or other securities under the Securities Act or such applicable securities laws in the relevant jurisdiction in connection with the public offering of such securities (other than an Exempt Registration), the
Company shall (i) promptly give the Preferred Shareholders written notice of such registration, and (ii) use commercially reasonable efforts to cause to be included in such registration, subject to the provisions of
Section 2.2(c), all of such Registrable Securities as are specified in a written request or requests made by any Preferred Shareholder received by the Company within fifteen (15) days after such written notice from the Company is
mailed. Such written request for inclusion may specify all or part of such Preferred Shareholder’s Registrable Securities. 

  

	 	(b)	The Company shall have the right to terminate or withdraw any registration initiated by it under this Section 2.2 prior to the effectiveness of such
registration whether or not any Preferred Shareholder has elected to include securities in such registration. The expenses of such withdrawn registration shall be borne by the Company. 

 

	 	(c)	Underwriting. 

  
 7 

	 	(i)	If the registration of which the Company gives notice is for a registered public offering involving an underwriting, the Company shall so advise the Preferred
Shareholders as part of the written notice given pursuant to Section 2.2(a) above. In such event, the right of a Preferred Shareholder to include securities in such registration pursuant to this Section 2.2 shall be
conditioned upon such Preferred Shareholder’s participation in such underwriting and the inclusion of its Registrable Securities in the underwriting to the extent provided herein and such Preferred Shareholder (together with the Company and
other Holders proposing to distribute securities through such underwriting (if any)) enter into an underwriting agreement in customary form with the underwriter(s) selected for such underwriting by the Company. 

 

	 	(ii)	Notwithstanding any other provision of this Section 2.2, if the underwriter in good faith determines that marketing factors require a limitation of the
number of shares to be underwritten, then the number of Registrable Securities that may be included in the registration and underwriting on behalf of the Company and the Holders shall be allocated in the following priority: 

 

	 	a)	first, to the Company; 

  

	 	b)	second, to the Preferred Shareholders in priority to all other shareholders of the Company but pro rata among themselves on the basis of the respective number of shares
of their Registrable Securities which they had requested to be included in such registration and underwriting; provided, however, that if such registration is the Company’s Qualified IPO, the underwriter may, upon a reasonable,
good faith determination, exclude all of the Preferred Shareholders’ Registrable Securities from such registration; provided, however, that the number of shares of Registrable Securities to be included in such underwriting and
registration shall not be reduced unless all other securities are first entirely excluded from the underwriting and registration including, without limitation, all shares that are not Registrable Securities and are held by any other person,
including, without limitation, any person who is an employee, officer or director of the Company or any subsidiary of the Company; provided, further, that if such registration is other than the Company’s Qualified IPO, the
underwriter may, upon a reasonable, good faith determination, limit the number of shares of the Preferred Shareholders’ Registrable Securities to be included in such registration to not less than twenty-five percent (25%) of the total
number of securities to be included in such registration and underwriting (with all other securities, other than securities being offered by the Company, having been first excluded from such registration); 

  
 8 

	 	c)	third, among all other holders of the Company’s securities having piggyback registration rights (pro rata among such holders on the basis of the respective amounts
of securities which such holders had requested to be included in such registration at the time of filing the registration statement). 

 To facilitate the allocation of shares in accordance with the above provisions, the Company or the underwriter(s) may round the number of shares allocated to any Holder to the nearest one hundred
(100) shares. 
 If any Preferred Shareholder after having inclusion in such registration as provided above does not agree
to the terms of any such underwriting, including signing a customary underwriting agreement on the same terms as the other Holders, such Preferred Shareholder shall be excluded therefrom by written notice from the Company or the underwriter. The
Registrable Securities or other securities so excluded shall also be withdrawn from such underwriting. Any Registrable Securities or other securities excluded or withdrawn from such underwriting shall be withdrawn from such registration. If shares
are so withdrawn from the registration and if the number of shares of Registrable Securities to be included in such registration was previously reduced as a result of marketing factors pursuant to this Section 2.2(c), the Company shall
then offer to all persons who have retained the right to include securities in the registration the right to include additional securities in the registration in an aggregate amount equal to the number of shares so withdrawn, with such shares to be
allocated among the persons requesting additional inclusion, in the manner set forth above. 
  

	 	2.3	Form F-3 Registration 

 In the event that the Company shall receive from a Preferred Shareholder a written request or requests that the Company effect a registration on Form F-3 and any related qualification or compliance with
respect to all or a part of the Registrable Securities owned by such Preferred Shareholder, the Company shall: 
  

	 	(a)	promptly give written notice of any related qualification or compliance, to such Preferred Shareholder; and 

 

	 	(b)	as soon as practicable, effect such registration and all such qualifications and compliances as may be so requested and as would permit or facilitate the sale and
distribution of all or such portion of such Preferred Shareholder’s Registrable Securities as are specified in such request, provided, however, that the Company shall not be obligated to effect any such registration, qualification
or compliance, pursuant to this Section 2.3: 

  

	 	(i)	if Form F-3 is not available for such offering; 

  
 9 

	 	(ii)	if such Preferred Shareholder, together with the holders of any other securities of the Company entitled to inclusion in such registration, proposes to sell Registrable
Securities and such other securities (if any) at an aggregate price to the public (net of any underwriters’ discounts or commissions) of less than US $1,000,000; 

 

	 	(iii)	if the Company shall furnish to such Preferred Shareholder a certificate signed by the Chief Executive Officer or Chairman of the Board of the Company stating that in
the good faith judgment of the Board of Directors of the Company, it would be seriously detrimental to the Company and its shareholders for such Form F-3 registration to be effected at such time, in which event the Company shall have the right to
defer the filing of the Form F-3 registration statement for a period of not more than ninety (90) days after receipt of the request of such Preferred Shareholder under this Section 2.3; provided, however, that the
Company shall not utilize this right more than once in any twelve (12) month period in relation to the same Preferred Shareholder; provided, further, that the Company shall not register any securities for the account of itself or
any other shareholder during such ninety (90) day period other than an Exempt Registration; or 

  

	 	(iv)	in any particular jurisdiction in which the Company would be required to qualify to do business or to execute a general consent to service of process in effecting such
registration, qualification or compliance. 

  

	 	(c)	Subject to the foregoing, the Company shall file a registration statement covering the Registrable Securities and other securities so requested to be registered as soon
as practicable after receipt of the request or requests of such Preferred Shareholder. Registrations effected pursuant to this Section 2.3 shall not be counted as requests for registration effected pursuant to Section 2.1. If
the registration is for an underwritten offering, the provisions of Section 2.1(c) and (d) shall apply. 

  

	 	2.4	Obligations of the Company 

  

	 	(a)	Whenever required by an Preferred Shareholder under this Section 2 to effect the registration of any Registrable Securities, the Company shall, as
expeditiously as reasonably possible: 

  

	 	(i)	prepare and file with the SEC a registration statement with respect to such Registrable Securities and use commercially reasonable efforts to cause such registration
statement to become effective (provided that before filing a registration statement or prospectus or any amendments or supplements thereto, the Company shall furnish to the counsel selected by the holders of not less than two-thirds (2/3) of
the Registrable Securities covered by such registration statement (if any) copies of all such documents proposed to be filed for review and comment by such counsel), and, upon the request of any Preferred Shareholder participating in such
registration, keep such registration statement effective for a period of up to one hundred twenty (120) days or, if earlier, until the distribution contemplated in the Registration Statement has been completed; provided, however, that
such 120-day period shall be extended for a period of time equal to the period such Preferred Shareholder refrains from selling any securities included in such registration at the request of an underwriter. 

  
 10 

	 	(ii)	prepare and file with the SEC such amendments and supplements to such registration statement and the prospectus used in connection with such registration statement as
may be necessary to comply with the provisions of the Securities Act with respect to the disposition of all securities covered by such registration statement (provided that before filing such amendments and supplements to such registration statement
and the prospectus, the Company shall furnish to the counsel selected by the holders of not less than two-thirds (2/3) of the Registrable Securities covered by such registration statement (if any) copies of all such documents proposed to be
filed for the review and comment by such counsel); 

  

	 	(iii)	furnish to each of the Preferred Shareholders participating in such registration such numbers of copies of a prospectus, including a preliminary prospectus, in
conformity with the requirements of the Securities Act, and such other documents as they may reasonably request in order to facilitate the disposition of Registrable Securities owned by them; 

 

	 	(iv)	use commercially reasonable efforts to register and qualify the securities covered by such registration statement under such other securities or Blue Sky laws of such
jurisdictions as shall be reasonably requested by such Preferred Shareholder, provided that the Company shall not be required in connection therewith or as a condition thereto to qualify to do business or to file a general consent to service
of process in any such states or jurisdictions; 

  

	 	(v)	in the event of any underwritten public offering, enter into and perform its obligations under an underwriting agreement, in customary form, with the managing
underwriter of such offering; provided, however, that such Preferred Shareholder shall also enter into and perform its obligations under such agreement; 

  
 11 

	 	(vi)	notify each of the Preferred Shareholders participating in such registration at any time when a prospectus relating thereto is required to be delivered under the
Securities Act or the happening of any event as a result of which the prospectus included in such registration statement, as then in effect, includes an untrue statement of a material fact or omits to state a material fact required to be stated
therein or necessary to make the statements therein not misleading in the light of the circumstances then existing; 

  

	 	(vii)	cause all such Registrable Securities registered pursuant hereunder to be listed on each securities exchange on which similar securities issued by the Company are then
listed; 

  

	 	(viii)	provide a transfer agent and registrar for all Registrable Securities registered pursuant hereunder and a CUSIP number for all such Registrable Securities, in each case
not later than the effective date of such registration; 

  

	 	(ix)	in an underwritten offering only, furnish a copy to each of the Preferred Shareholders participating in such registration, of (i) the opinion of the counsel
representing the Company delivered to the underwriters, and (ii) the “comfort” letter from the independent certified public accountants of the Company in customary form and covering such matters of the type customarily covered by
comfort letters delivered to the underwriters, but only in such instances where (i) and (ii) are actually delivered to the underwriters; 

  

	 	(x)	make available for inspection by any Preferred Shareholder participating in such registration, any underwriter participating in any disposition pursuant to such
registration statement, and any attorney, accountant or other agent retained by any such seller or underwriter, all financial and other records, pertinent corporate documents and properties of the Company reasonably requested in connection with the
registration statement, and cause the Company’s officers, directors, employees and independent accountants to supply all information reasonably requested by any such seller, underwriter, attorney, accountant or agent in connection with such
registration statement, to the extent permitted by applicable law and regulation; 

  

	 	(xi)	otherwise use commercially reasonable efforts to comply with all applicable rules and regulations of the SEC; 

  
 12 

	 	(xii)	if any such registration or comparable statement refers to any holder by name or otherwise as the holder of any securities of the Company and if such holder is or might
be deemed to be an underwriter or a controlling person of the Company, such holder shall have the right to require (a) the insertion therein of language, in form and substance satisfactory to such holder and presented to the Company in writing,
to the effect that the holding by such holder of such securities is not to be construed as a recommendation by such holder of the investment quality of the Company’s securities covered thereby and that such holding does not imply that such
holder shall assist in meeting any future financial requirements of the Company, or (b) in the event that such reference to such holder by name or otherwise is not required by the Securities Act or any similar Federal statute then in force, the
deletion of the reference to such holder; provided, that, with respect to this Section 2.4(a)(xii) such holder shall furnish to the Company an opinion of counsel to such effect, which opinion and counsel shall be reasonably
satisfactory to the Company; 

  

	 	(xiii)	in the event of the issuance of any stop order suspending the effectiveness of a registration statement, or of any order suspending or preventing the use of any related
prospectus or suspending the qualification of any Ordinary Shares included in such registration statement for sale in any jurisdiction, the Company shall use commercially reasonable efforts promptly to obtain the withdrawal of such order;

  

	 	(xiv)	use best efforts to cause such Registrable Securities covered by such registration statement to be registered with or approved by such other governmental agencies or
authorities as may be necessary to enable the sellers thereof to consummate the disposition of such Registrable Securities; and 

  

	 	(xv)	use best efforts to take all such other actions as the holders of not less than two-thirds (2/3) of the Registrable Securities being sold or the underwriters, if
any, reasonably request in order to expedite or facilitate the disposition of such Registrable Securities (including effecting a share split or a combination of shares). 

 

	 	2.5	Information From Preferred Shareholder 

 It shall be a condition precedent to the obligations of the Company to take any action pursuant to this Section 2 with respect to the Registrable Securities that the relevant Preferred
Shareholder shall in a timely manner furnish to the Company such information regarding itself, the Registrable Securities held by it, and the intended method of disposition of such securities as shall be required to effect the registration of such
Preferred Shareholder’s Registrable Securities. 
  

	 	2.6	Expenses of Registration 

 All expenses other than underwriting discounts and commissions incurred in connection with registrations, filings or qualifications pursuant to Sections 2.1, 2.2 and 2.3, including (without
limitation) all registration, filing and qualification fees, printers’ and accounting fees, fees and disbursements of counsel for the Company and the reasonable fees and disbursements of one counsel for each Preferred Shareholder, shall be
borne by the Company. 

  
 13 

	 	2.7	Indemnification 

In the event any Registrable Securities are included in a registration statement under this Section 2: 

 

	 	(a)	To the fullest extent permitted by law, the Company will indemnify and hold harmless the relevant Preferred Shareholder, each of its partners or officers, directors and
shareholders, legal counsel and accountants, underwriter (as defined in the Securities Act) and each person, if any, who controls such Preferred Shareholder or underwriter within the meaning of the Securities Act or the Exchange Act, against any
losses, claims, damages or liabilities (joint or several) to which they may become subject under the Securities Act, the Exchange Act or any state securities laws, insofar as such losses, claims, damages, or liabilities (or actions in respect
thereof) arise out of or are based upon any of the following statements, omissions or violations (collectively a “Violation”): (i) any untrue statement or alleged untrue statement of a material fact contained in such
registration statement, including any preliminary prospectus or final prospectus contained therein or any amendments or supplements thereto, (ii) the omission or alleged omission to state therein a material fact required to be stated therein,
or necessary to make the statements therein not misleading, or (iii) any violation or alleged violation by the Company of the Securities Act, the Exchange Act, any state securities laws or any rule or regulation promulgated under the Securities
Act, the Exchange Act or any applicable securities laws; and the Company will reimburse such Preferred Shareholder, underwriter or controlling person for any legal or other expenses reasonably incurred by them in connection with investigating or
defending any such loss, claim, damage, liability or action; provided, however, that the indemnity agreement contained in this Section 2.7(a) shall not apply to amounts paid in settlement of any such loss, claim, damage,
liability or action if such settlement is effected without the consent of the Company (which consent shall not be unreasonably withheld), nor shall the Company be liable in any such case for any such loss, claim, damage, liability or action to the
extent that it arises out of or is based upon a Violation that occurs in reliance upon and in conformity with written information furnished for use in connection with such registration by such Preferred Shareholder, underwriter or controlling
person; provided, further, however, that the foregoing indemnity agreement with respect to any preliminary prospectus shall not inure to the benefit of such Preferred Shareholder or underwriter, or any person controlling such Preferred
Shareholder or underwriter, from whom the person asserting any such losses, claims, damages or liabilities purchased shares in the offering, if a copy of the prospectus (as then amended or supplemented if the Company shall have furnished any
amendments or supplements thereto) was not sent or given by or on behalf of such Preferred Shareholder or underwriter to such person, if required by law so to have been delivered, at or prior to the written confirmation of the sale of the shares to
such person, and if the prospectus (as so amended or supplemented) would have cured the defect giving rise to such loss, claim, damage or liability. 

  
 14 

	 	(b)	To the extent permitted by law, the relevant Preferred Shareholder will indemnify and hold harmless the Company, each of its directors, each of its officers who has
signed the registration statement, each person, if any, who controls the Company within the meaning of the Securities Act, legal counsel and accountants for the Company, any underwriter, any other Holder selling securities in such registration
statement and any controlling person of any such underwriter or other Holder, against any losses, claims, damages or liabilities to which any of the foregoing persons may become subject, under the Securities Act, the Exchange Act or any state
securities laws, insofar as such losses, claims, damages or liabilities (or actions in respect thereto) arise out of or are based upon any Violation, in each case to the extent (and only to the extent) that such Violation occurs in reliance upon and
in conformity with written information furnished by such Preferred Shareholder for use in connection with such registration; and such Preferred Shareholder will reimburse any person intended to be indemnified pursuant to this
Section 2.7(b) for any legal or other expenses reasonably incurred by such person in connection with investigating or defending any such loss, claim, damage, liability or action; provided, however, that the indemnity
agreement contained in this Section 2.7(b) shall not apply to amounts paid in settlement of any such loss, claim, damage, liability or action if such settlement is effected without the consent of such Preferred Shareholder (which consent
shall not be unreasonably withheld), provided that the relevant Preferred Shareholder’s obligation to indemnify contained in this Section 2.7(b) shall be individual, not joint and several and in no event shall any indemnity under
this Section 2.7(b) exceed the net proceeds from the offering received by such Preferred Shareholder. 

  

	 	(c)	Promptly after receipt by an indemnified party under this Section 2.7 of notice of the commencement of any action (including any governmental action), such
indemnified party will, if a claim in respect thereof is to be made against any indemnifying party under this Section 2.7, deliver to the indemnifying party a written notice of the commencement thereof and the indemnifying party shall
have the right to participate in, and, to the extent the indemnifying party so desires, jointly with any other indemnifying party similarly noticed, to assume the defense thereof with counsel mutually satisfactory to the parties; provided,
however, that an indemnified party (together with all other indemnified parties which may be represented without conflict by one counsel) shall have the right to retain one separate counsel, with the fees and expenses to be paid by the
indemnifying party, if representation of such indemnified party by the counsel retained by the indemnifying party would be inappropriate due to actual or potential differing interests between such indemnified party and any other party represented by
such counsel in such proceeding. The failure to deliver written notice to the indemnifying party within a reasonable time of the commencement of any such action, if prejudicial to its ability to defend such action, shall relieve such indemnifying
party of any liability to the indemnified party under this Section 2.7, but the omission so to deliver written notice to the indemnifying party will not relieve it of any liability that it may have to any indemnified party otherwise than
under this Section 2.7. 

  
 15 

	 	(d)	The indemnification provided for under this Agreement shall remain in full force and effect regardless of any investigation made by or on behalf of the indemnified
party or any officer, director or controlling person of such indemnified party and shall survive the transfer of securities. The Company also agrees to make such provisions, as are reasonably requested by any indemnified party, for contribution to
such party in the event the Company’s indemnification is unavailable for any reason. 

  

	 	(e)	If the indemnification provided for in this Section 2.7 is held by a court of competent jurisdiction to be unavailable to an indemnified party with respect to any
loss, liability, claim, damage or expense referred to herein, then the indemnifying party, in lieu of indemnifying such indemnified party hereunder, shall contribute to the amount paid or payable by such indemnified party as a result of such loss,
liability, claim, damage or expense in such proportion as is appropriate to reflect the relative fault of the indemnifying party on the one hand and of the indemnified party on the other in connection with the statements or omissions that resulted
in such loss, liability, claim, damage or expense, as well as any other relevant equitable considerations. The relative fault of the indemnifying party and of the indemnified party shall be determined by reference to, among other things, whether the
untrue or alleged untrue statement of a material fact or the omission to state a material fact relates to information supplied by the indemnifying party or by the indemnified party and the parties’ relative intent, knowledge, access to
information, and opportunity to correct or prevent such statement or omission. 

  

	 	(f)	Notwithstanding the foregoing, to the extent that the provisions on indemnification and contribution contained in the underwriting agreement entered into in connection
with the underwritten public offering are in conflict with the foregoing provisions, the provisions in the underwriting agreement shall control. 

  

	 	(g)	The obligations of the Company and the relevant Preferred Shareholder under this Section 2.7 shall survive the completion of any offering of Registrable
Securities in a registration statement under this Section 2, and otherwise. 

  
 16 

	 	2.8	Reports Under the Exchange Act 

 With a view to making available to the Preferred Shareholders the benefits of Rule 144 and any other rule or regulation of the SEC that may at any time permit the Preferred Shareholders to sell securities
of the Company to the public without registration or pursuant to a registration on Form F-3, the Company agrees to: 
  

	 	(a)	make and keep current public information available, as those terms are understood and defined in Rule 144(c), at all times after ninety (90) days after the
effective date of a Qualified IPO; 

  

	 	(b)	file with the SEC in a timely manner all reports and other documents required of the Company under the Securities Act and the Exchange Act; and

  

	 	(c)	furnish to each Preferred Shareholder, so long as such Preferred Shareholder owns any Registrable Securities, forthwith upon request (i) a written statement by the
Company that it has complied with the reporting requirements of Rule 144 (at any time after ninety (90) days after the effective date of the first registration statement filed by the Company), the Securities Act and the Exchange Act (at any
time after it has become subject to such reporting requirements), or that it qualifies as a registrant whose securities may be resold pursuant to Form F-3 (at any time after it so qualifies), (ii) a copy of the most recent annual or quarterly
report of the Company and such other reports and documents so filed by the Company, and (iii) such other information as may be reasonably requested in availing such Preferred Shareholder of any rule or regulation of the SEC that permits the
selling of any such securities without registration or pursuant to such form. 

  

	 	2.9	Assignment of Registration Rights 

 The rights to cause the Company to register Registrable Securities pursuant to this Section 2 may be assigned (but only with all related obligations) by a Preferred Shareholder to a transferee
or assignee of such securities; provided that (a) the Company is, within a reasonable time after such transfer, furnished with written notice of the name and address of such transferee or assignee and the securities with respect to which
such registration rights are being transferred or assigned; (b) such transferee or assignee agrees in writing to be bound by and subject to the terms and conditions of this Agreement, including without limitation the provisions of
Section 2.11 below; and (c) such assignment shall be effective only if immediately following such transfer or assignment the further disposition of such securities by the transferee or assignee is restricted under the Securities
Act. 
  

	 	2.10	Limitations on Subsequent Registration Rights 

  

	 	(a)	From and after the date of this Agreement, the Company shall not, without the prior written consent of holders of not less than 51% of the outstanding Preferred Shares,
enter into any agreement with any holder or prospective holder of any securities of the Company that would give such holder or prospective holder any registration rights, the terms of which are more favorable than, or on parity with, the
registration rights granted to the Preferred Shareholder hereunder. 

  
 17 

	 	2.11	“Market Stand-Off” Agreement 

 If requested by the Company and an underwriter of the Company, the Preferred Shareholders shall not sell or otherwise transfer or dispose of any securities of the Company held by the Preferred
Shareholders other than those included in the registration immediately prior to and during the one hundred eighty (180) day period following the effective date of a registration statement of the Company filed under the Securities Act in
connection with the Company’s Qualified IPO (and in the case of a secondary public offering, immediately prior to and during the ninety (90) day period following the effective date of a registration statement). The obligations described in
this Section 2.11 shall not apply to a registration relating solely to employee benefit plans on Form S-8 or similar forms that may be promulgated in the future, or a registration relating solely to a transaction of Form F-4 or similar
forms that may be promulgated in the future. The Preferred Shareholders agree to execute a market standoff agreement with said underwriters in customary form consistent with the provisions of this Section 2.11, provided that the
Founders, the existing holders of the Ordinary Shares, and all officers or directors and greater than five percent (5%) shareholders of the Company enter into similar agreements. The underwriters in connection with the Company’s initial
and secondary public offering are intended third party beneficiaries of this Section 2.11 and shall have the right, power and authority to enforce the provisions hereof as though they were a party hereto. 

In order to enforce the foregoing covenant, the Company may impose stop-transfer instructions with respect to the Registrable Securities
of the Preferred Shareholders (and the shares or securities of every other person subject to the foregoing restriction) until the end of such period. 
  

	 	2.12	Termination of Registration Rights 

 The right of a Preferred Shareholder to include Registrable Securities in any registration pursuant to Section 2.1, 2.2 or 2.3 shall terminate upon the first to occur of:
(i) when the shares of Registrable Securities beneficially owned or subject to Rule 144 aggregation by such Preferred Shareholder may be sold under Rule 144 or Regulation S during any 90-day period; or (ii) five (5) years
following the date of the Company’s Qualified IPO. 
  

	3.	MISCELLANEOUS 

  

	 	3.1	Successors and Assigns 

 Except as otherwise provided herein, the terms and conditions of this Agreement shall inure to the benefit of and be binding upon the respective successors and assigns of the parties (including

liabilities under or by reason of this Agreement, except as expressly provided in this Agreement.

execute a joinder to this Agreement in the form of Exhibit B hereto. Upon delivery of any such joinder to other parties hereof, notice of which is hereby waived by the parties hereto, each such Additional Preferred Shareholder shall be as
fully a party hereto as if such Additional Preferred Shareholder were an original signatory hereof.

	 	(b)	If to the Company, one copy should be sent to its principal address or facsimile number and addressed to the attention of the President, or at such other address or
facsimile number as the Company shall have furnished to such Preferred Shareholder. 

 Each such notice or other

with the applicable postal services, addressed and mailed as aforesaid or, if sent by facsimile, on the next business day after the date of confirmation of facsimile transfer or, if sent by courier or overnight delivery, three (3) days after

	 	3.8	Entire Agreement: Amendments and Waivers 

 This Agreement (including the Exhibits hereto, if any) constitutes the full and entire understanding and agreement between the parties with regard to the subjects hereof and thereof and supersedes all
prior agreements and understandings with respect to the subject matter hereof. 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 Preferred Shareholders. 
  

	 	3.9	Severability 

 If

	 	3.10	Delays or Omissions 

Except as expressly provided herein, no delay or omission to exercise any right, power or remedy accruing to any party to this Agreement
upon any breach or default of any other party under this Agreement shall impair any such right, power or remedy of such non-defaulting party, nor shall it be construed to be a waiver of any such breach or default, or any 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
of 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 to this Agreement, shall be cumulative and not alternative. 

  
 20 

	 	3.11	Further Instrument and Actions 

 The parties hereto agree to execute such further instruments and to take such further action (including the exercise of all voting rights and other power of control available to them in relation to the
Company and its Subsidiaries) as may reasonably be necessary to carry out the intent of this Agreement. 
  

	 	3.12	Memorandum and Articles of Association 

 In the event of any conflict or inconsistency between the memorandum and articles of association of the Company and this Agreement, the provisions of the memorandum and articles of association of the
Company shall prevail. 
  

	 	3.13	Newco 

 In the
event of a new Listing Vehicle being formed and in which the Preferred Shareholders hold any share or securities, the parties hereto shall procure that the new Listing Vehicle and the Preferred Shareholders shall enter into a new registration rights
agreement in substantially the same terms and conditions as this Agreement to govern the registration rights of the Preferred Shareholders in respect of such shares or securities in the new Listing Vehicle. 

 

	 	3.14	Prior Agreement 

This Agreement shall supersede the Prior Agreement and all other prior agreements regarding the subject matter hereof, which shall cease
to have any force and effect as from the date hereof save for any antecedent breach prior to date hereof.
