 ARTICLE II 
 ANTI-DILUTION 
 2.01 Adjustment to Conversion Price. If the Company issues Additional Shares
for a consideration per share (as determined by in accordance with Section 2.04 below) less than the Conversion Price (as defined in the Restated Articles) in effect immediately prior to such issue, then and in such event, the then-effective
Conversion Price shall be reduced concurrently with such issue, to such Conversion Price multiplied by the fraction of: 
 (i) sum of
(x) the number of Ordinary Shares outstanding immediately prior to such issue or sale of Additional Shares plus (y) the aggregate consideration received by the Company in connection with the issue or sale of Additional Shares
divided by the Conversion Price in effect immediately prior to such issue or sale; divided by 
 (ii) sum of (x) the number
of Ordinary Shares outstanding immediately prior to such issue or sale of Additional Shares plus (y) the number of Additional Shares so issued or sold 
 provided that for the purpose of this Section 2.01, the number of Ordinary Shares outstanding immediately prior to such issue or sale of Additional Shares shall be calculated to include the number of Ordinary Shares which are issued
and outstanding or owned or held, as applicable, at the date of determination plus the number of Ordinary Shares issuable pursuant to any securities, warrants, rights or Options then outstanding, convertible into or exchangeable or exercisable for
(whether or not subject to contingencies or passage of time, or both) Ordinary Shares. 
 2.02 No Adjustment to Conversion Price. No
adjustment in the Conversion Price shall be made in respect of the issuance or deemed issuance of Additional Shares if the Company receives written notice from the holders of at least 80% of the then outstanding Series A Shares agreeing that no such
adjustment shall be made as the result of the issuance or deemed issuance of such Additional Shares. 
 2.03 Deemed Issuance of
Additional Share. In the event that the Company at any time or from time to time after the Closing Date shall issue any Options or Convertible Securities or shall fix a record date for the determination of holders of any class of securities
entitled to receive any such Options or Convertible Securities, then the maximum number (as set forth in the instrument relating thereto without regard to any provisions contained therein for a subsequent adjustment of such number that would result
in an adjustment pursuant to sub-paragraph (ii) below) of Ordinary Shares issuable upon the exercise of such Options or, in the case of Convertible Securities, the conversion or exchange of such Convertible Securities, shall be deemed to be
Additional Shares issued as of the time of such issuance or, in case such a record date shall have been fixed, as of the close of business on such record date; provided that Additional Shares shall not be deemed to have been issued with respect to
the Series A Shares unless the consideration per share (determined pursuant to Section 2.04 hereof) of such Additional Shares would be less than the Conversion Price in effect on the date of and immediately prior to such issuance, or such
record date, as the case may be, and provided further that in any such case in which Additional Shares are deemed to be issued: 
 (i) no
further adjustment to the Conversion Price shall be made upon the subsequent issuance of Ordinary Shares upon the exercise of such Options or conversion or exchange of such Convertible Securities; 
  

 - 5 - 

 (ii) if such Options or Convertible Securities by their terms provide, with the passage of time or
otherwise, for any increase or decrease in the consideration payable to the Company, or increase or decrease in the number of Ordinary Shares issuable, upon the exercise, conversion or exchange thereof, the Conversion Price computed upon the
original issuance thereof (or upon the occurrence of a record date with respect thereto), and any subsequent adjustments based thereon, shall, upon any such increase or decrease becoming effective be recomputed to reflect such increase or decrease
insofar as it affects such Options or the rights of conversion or exchange under such Convertible Securities; 
 (iii) upon the expiration of
any such Options or any rights of conversion or exchange under such Convertible Securities which have not been exercised or fully exercised, the Conversion Price computed upon the original issuance thereof (or upon the occurrence of a record date
with respect thereto), and any subsequent adjustments based thereon, shall, upon such expiration, be recomputed as if: 
 (A) in the case of
Convertible Securities or Options for Ordinary Shares, the only Additional Shares issued were Ordinary Shares, if any, actually issued upon the exercise of such Options or the conversion or exchange of such Convertible Securities, and the
consideration received therefor was the consideration actually received by the Company for the issuance of all such Options or Convertible Securities, whether or not exercised or converted, plus the consideration actually received by the Company
upon such exercise, conversion or exchange, or for the issuance of all such Convertible Securities which were actually converted or exchanged, plus the additional consideration, if any, actually received by the Company upon such conversion or
exchange, and 
 (B) in the case of Options for Convertible Securities, only the Convertible Securities, if any, actually issued upon the
exercise thereof were issued at the time of issuance of such Options, and the consideration received by the Company for the Additional Shares deemed to have been then issued was the consideration actually received by the Company for the issuance of
all such Options, whether or not exercised, plus the consideration deemed to have been received by the Company upon the issuance of the Convertible Securities with respect to which such Options were actually exercised; provided that 
 (I) no readjustment pursuant to sub-paragraph (ii) or (iii) above shall have the effect of increasing the Conversion Price to an amount which
exceeds the lower of (x) the Conversion Price on the original adjustment date, or (y) the applicable Conversion Price that would have resulted from any issuance of Additional Shares between the original adjustment date and such
readjustment date; and 
  

 - 6 - 

 (II) in the case of any Options which expire by their terms not more than thirty (30) days after
the date of issuance thereof, no adjustment of the Conversion Price shall be made until the expiration or exercise of all such Options, whereupon such adjustment shall be made in the manner provided in sub-paragraph (iii) above. 
 2.04 Determination of Consideration. For purposes of Article II, the consideration received by the Company for the issuance of any Additional
Shares shall be computed as follows: 
 (i) Cash and Property. such consideration shall: 
 (A) insofar as it consists of cash, be computed at the aggregate amount of cash received by the Company excluding amounts paid or payable for accrued
interest or accrued dividends; 
 (B) insofar as it consists of property other than cash, be computed at the fair value thereof at the time
of such issuance, as determined in good faith by the Board; provided, however, that no value shall be attributed to any services performed by any employee, officer or director of the Company; and 
 (C) in the event Additional Shares are issued together with other shares or securities or other assets of the Company for consideration which covers
both, be the proportion of such consideration so received with respect to such Additional Shares, computed as provided in this sub-paragraph (i), as determined in good faith by the Board. 
 (ii) Options and Convertible Securities. The consideration per share received by the Company for Additional Shares deemed to have been issued
pursuant to Section 2.03, relating to Options and Convertible Securities, shall be determined by dividing: 
 (A) the total amount, if
any, received or receivable by the Company as consideration for the issuance of such Options or Convertible Securities, plus the minimum aggregate amount of additional consideration (as set forth in the instruments relating thereto, without regard
to any provision contained therein for a subsequent adjustment of such consideration) payable to the Company upon the exercise of such Options or the conversion or exchange of such Convertible Securities, or in the case of Options for Convertible
Securities, the exercise of such Options for Convertible Securities and the conversion or exchange of such Convertible Securities, by 
 (B)
the maximum number of Ordinary Shares (as set forth in the instruments relating thereto, without regard to any provision contained therein for a subsequent adjustment of such number) issuable upon the exercise of such Options or the conversion or
exchange of such Convertible Securities.

 ARTICLE III 
 ADJUSTMENT FOR SHARE SPLITS, COMBINATIONS AND SO FORTH 
 In the event that the outstanding Ordinary
Shares shall be subdivided (by share dividend, share split, or otherwise) into a greater number of Ordinary Shares, the Conversion Price then in effect shall, concurrently with the effectiveness of such subdivision, be proportionately decreased. In
the event the outstanding Ordinary Shares shall be combined or consolidated, by reclassification or otherwise, into a lesser number of Ordinary Shares, the Conversion Price then in effect shall, concurrently with the effectiveness of such
combination or consolidation, be proportionately increased. 
 ARTICLE IV 
 RIGHT OF CO-SALE 
 4.01 Transfer Notice. If at any time (i) Genius
or any other holder (or holders together) of at least 30% of the issued Ordinary Shares (the “Selling Shareholder”) proposes to, directly or indirectly, sell, transfer, pledge or otherwise dispose of or permit the sale, transfer,
pledge, or other disposition of its Ordinary Shares or any other securities of the Company (each disposition, a “Transfer”), in whole or in part, to one or more third parties, such Selling Shareholder shall give the Investors
written notice of the intention to make such Transfer (the “Transfer Notice”). Such Transfer Notice shall include (i) a description of the securities to be Transferred (the “Offered Shares”), (ii) the
identity of the prospective transferee(s), and (iii) the consideration and the material terms and conditions upon which the proposed Transfer is to be made. The Transfer Notice shall certify that the Selling Shareholder has received a firm
offer from the prospective transferee(s) and in good faith believes a binding agreement for the Transfer is obtainable on the terms set forth in the Transfer Notice. The Transfer Notice shall also include a copy of any written proposal, term sheet
or letter of intent or other agreement relating to the proposed Transfer. 
 4.02 Investors’ Right of Co-Sale. (i) Subject to
Section 4.03 below, each Investor may, by giving written notice to the Selling Shareholder (the “Co-Sale Notice”) within thirty (30) days after its receipt of the Transfer Notice, notify the Selling Shareholder that such
Investor wishes to sell a portion of the securities then held thereby pursuant to this Section 4.02 and the number of securities to be sold (subject to Section 4.02(ii)). Such Investor (a “Co-Sale Participant”) shall
therefore have the right to participate in the sale of Offered Shares, on the same terms and conditions as specified in the Transfer Notice. To the extent one or more Investors exercise its right of co-sale in accordance with the terms and
conditions set forth below, the number of securities that the Selling Shareholder may sell in the Transfer shall be correspondingly reduced. 
  

 - 8 -

held by such Co-Sale Participant, or issued upon conversion of Series A Shares owned by such Co-Sale Participant equal to the product obtained by multiplying (i) the Offered Shares, by (ii) a fraction, the numerator of which shall be the
number of Ordinary Shares then issued and held by such Co-Sale Participant, or issuable upon conversion of Series A Shares owned by such Co-Sale Participant and the denominator of which shall be the total number of Ordinary Shares issued and
outstanding on a fully-diluted basis, calculated immediately prior to the time of the Transfer. 
 4.03 Limitations. The provisions
of Section 4.02 shall not apply to any proposed Transfer of Ordinary Shares by any Ordinary Shareholder that is: 
 (i) for nominal
consideration to Affiliates of such Ordinary Shareholder; or 
 (ii) to TB upon TB’s enforcement of the Share Charge Agreement.

 ARTICLE V 
 PUT OPTION

 5.01 First Put Right. In the event of a breach by Genius and/or the Company of any covenant under Sections 4.02 of the Share
Purchase Agreement, the Investors shall have the right to request the Company to redeem (or request Genius to purchase) all or any part of the Purchased Shares that the Investors then hold (including the additional shares the Investors receive
pursuant to the anti-dilution provisions as provided above) at a price per share equal to (i) 100% of the Series A Issue Price then in effect (as defined in the Restated Articles) (as adjusted for share splits, share dividends,
recapitalizations or the like proportionately or adjusted pursuant to the anti-dilution mechanism as provided herein) plus (ii) all accrued but unpaid dividends (the “First Put Right”). For the avoidance of doubt, the Investors
may exercise the First Put Right once and not more than once. 
 5.02 Second Put Right. If the Audited Consolidated EBIT for the
period beginning January 1, 2007 and ending March 31, 2008 is less than US$20 million, the Investors may, by serving a written notice to the Company (or Genius), request the Company to redeem (or Genius to purchase) all or part of the
Purchased Shares the Investors then hold (including the additional shares the Investors receive pursuant to the anti-dilution provisions as provided above) (the “Second Put Shares”), at a price per share equal to (i) 150% of
the Series A Issue Price then in effect (as adjusted for share splits, share dividends, recapitalizations or the like proportionately or adjusted pursuant to the anti-dilution mechanism as provided herein) (the “Option Price Per
Share”), plus (ii) all accrued but unpaid dividends (the “Second Put Right”). 
  

 - 9 - 

 If, within one hundred and twenty (120) days after the written notice is served, the Company (or
Genius) does not have sufficient cash legally available to redeem (or purchase) all of the Second Put Shares, Genius shall charge a number of Ordinary Shares (the “Second Put Charged Shares”) to each Investor such that, for each
Investor, the aggregate fair market value of (i) the Second Put Charged Shares and (ii) the Second Put Shares remaining to be redeemed or purchased (and, only with respect to TB, also including the Existing Charged Shares, if any) is equal
to the total put price (calculated based on the Option Price Per Share) of the Second Put Shares remaining to be redeemed or purchased. 
 In
the event that Genius is required to charge the Second Put Charged Shares to the Investors as a result of the Investors’ enforcement of the Second Put Right, Genius shall execute one or more additional share charge agreements substantially
similar to the Share Charge Agreement in form and substance with respect to such Second Put Charged Shares. 
 The Company (or Genius) shall
undertake to redeem (or purchase) the Second Put Shares remaining to be redeemed or purchased within 12 months after the date of the share charge agreement entered into for the Second Put Charged Shares, failing which the Investors may foreclose
upon the Second Put Charged Shares (and, only with respect to TB, the Existing Charged Shares, if any) by taking ownership of such Ordinary Shares, and the Company and Genius shall provide all necessary assistance and take all reasonable actions to
complete and effect such transfer. Upon completion of such foreclosure, the Company and Genius shall be deemed to have fulfilled their redemption or purchase obligations in relation to such Second Put Shares remaining to be redeemed or purchased, of
which the Investors shall continue to be the owner. In the event that the Company or Genius has raised the necessary fund and redeemed or purchased the Second Put Shares remaining to be redeemed or purchased within the above 12 months period, the
Investors shall release the Second Put Charged Shares (and, only with respect to TB, the Existing Charged Shares, if any) to Genius. 
 For
the avoidance of doubt, the Investors may exercise the Second Put Right once and not more than once. 
 5.03 Third Put Right. If the
Company has not achieved a Qualified IPO within three (3) years after the Closing Date, within thirty (30) days after the third anniversary of the Closing Date, the Investors may, by serving a written notice to the Company (or Genius),
request the Company to redeem (or Genius to purchase) all or any part of the outstanding Purchased Shares the Investors then hold (including the additional shares the Investors receive pursuant to the anti-dilution provisions as provided above) (the
“Third Put Shares”) at the Option Price Per Share, plus all accrued but unpaid dividends (the “Third Put Right”), provided that the Investors have not exercised the Second Put Right. 
 If, within one hundred and twenty (120) days after the written notice is served, the Company (or Genius) does not have sufficient cash legally
available to redeem (or purchase) all the Third Put Shares, Genius shall charge a number of Ordinary Shares (the “Third Put Charged Shares”) to each Investor such that, for each Investor, the aggregate fair market value of
(i) the Third Put Charged Shares and (ii) the Third Put Shares remaining to be redeemed or purchased (and, only with respect to TB, also including the Existing Charged Shares, if any) is equal to the total put price (calculated based on
the Option Price Per Share) of the Third Put Shares remaining to be redeemed or purchased. 
  

 - 10 - 

 In the event that Genius is required to charge Third Put Charged Shares to the Investors as a result of
the Investors’ enforcement of the Third Put Right, Genius shall execute one or more additional share charge agreements substantially similar to the Share Charge Agreement in form and substance with respect to such Third Put Charged Shares.

 The Company (or Genius) shall undertake to redeem (or purchase) the Third Put Shares remaining to be redeemed or purchased within 12
months after the date of the share charge agreement entered into for the Third Put Charged Shares, failing which the Investors may foreclose upon the Third Put Charged Shares (and, only with respect to TB, the Existing Charged Shares, if any) by
taking ownership of such Ordinary Shares, and the Company and Genius shall provide all necessary assistance and take all reasonable actions to complete and effect such transfer. Upon completion of such foreclosure, the Company and Genius shall then
be deemed to have fulfilled their redemption or purchase obligations in relation to such Third Put Shares remaining to be redeemed or purchased, of which the Investors shall continue to be the owner. In the event that the Company or Genius has
raised the necessary fund and redeemed or purchased the Third Put Shares remaining to be redeemed or purchased within the above 12 months period, the Investors shall release the Third Put Charged Shares (and, only with respect to TB, the Existing
Charged Shares, if any) to Genius. 
 For the avoidance of doubt, the Investors may exercise the Third Put Right once and not more than once.

pursuant to this Section 3.03, the Company shall (i) within ten (10) Business Days of the receipt of such written request, give written notice of such request (“Request Notice”) to all other Holders and other
shareholders of the Company with piggyback registration rights, and (ii) use its commercially reasonable efforts to effect, as soon as practicable, the registration under the Securities Act of all Registrable Securities that the Initiating
Holders request to be registered, together with all Registrable Securities of any other Holders requested to be included in such registration by written notice given by such other Holders to the Company within twenty (20) days after receipt of
the Request Notice, subject only to the limitations of this Section 3.03; provided that the Company shall not be obligated to effect any such registration (x) if the Company has already effected twice, within the twelve
(12) month period preceding the date of such request, a Registration under the Securities Act pursuant to this Section 3.03 or Section 3.05 or in which the Holders had an opportunity to participate pursuant to the provisions of
Section 3.04, other than a registration from which the Registrable Securities of the Holders have been excluded (with respect to all or any portion of the Registrable Securities the Holders requested be included in such registration) pursuant

registration of securities and laws of and equivalent government authority in the applicable non-United States jurisdiction. 
 (b)
Underwriting. If the Initiating Holders intend to distribute the Registrable Securities covered by their request by means of an underwriting, then they shall so advise the Company as a part of their request made pursuant to this
Section 3.03 and the Company shall include such information in the Request Notice. In such event, the right of any other Holder to include its Registrable Securities in such registration shall be conditioned upon such other Holder’s
participation in such underwriting and the inclusion of 

  

 - 9 - 

 
such Holder’s Registrable Securities in the underwriting (unless otherwise mutually agreed by a majority in interest of the Initiating Holders and such
other Holder) to the extent provided herein. All Holders proposing to distribute their Registrable Securities through such underwriting shall enter into an underwriting agreement in customary form with the managing underwriter or underwriters
selected for such underwriting by the Company; provided, however, that if a majority in interest of the Initiating Holders have not agreed with such underwriter as to terms and conditions of such underwriting within twenty
(20) days following commencement of such negotiations, a majority in interest of the Initiating Holders may select an underwriter of their choice. Notwithstanding any other provision of this Agreement but subject to Section 3.13, if the
underwriter(s) advise(s) the Company in writing in good faith that marketing factors require a limitation of the number of securities to be underwritten, then the Company shall so advise all Holders which would otherwise be registered and
underwritten pursuant hereto, and the number of Registrable Securities that may be included in the underwriting shall be reduced as required by the underwriter(s) and allocated among the Holders on a pro rata basis according to the number of
Registrable Securities then outstanding held by each Holder requesting registration (including the Initiating Holders); provided, however, that the right of the underwriter(s) to exclude shares (including Registrable Securities) from
the registration and underwriting as described in this Section 3.04(b) shall be restricted so that (i) the number of Registrable Securities included in such registration and underwriting is not reduced to below thirty percent (30%) of
the aggregate number of Registrable Securities for which inclusion has been requested by the Initiating Holders; and (ii) all other securities that are not Registrable Securities, including, but not limited to, Ordinary Shares or all other
shares that are not Registrable Securities and are held by any other person, including, without limitation, any person who is an employee, consultant, officer or director of the Company (or any Subsidiary of the Company) shall first be excluded in
entirety from such registration and underwriting before any Registrable Securities are so excluded. If any Holder disapproves of the terms of any such underwriting, such Holder may elect to withdraw therefrom by written notice to the Company and the
underwriter(s), delivered at least ten (10) Business Days prior to the effective date of the registration statement. If, by the withdrawal of such Registrable Securities, a greater number of Registrable Securities held by other Holders may be
included in such registration (up to the limit imposed by the underwriters), the Company shall offer to all Holders who have included Registrable Securities in the registration the right to include additional Registrable Securities in the same
proportion used in determining the limitation as set forth above. Any Registrable Securities excluded or withdrawn from such underwriting shall be excluded and withdrawn from the registration. 
 (c) Maximum Number of Demand Registrations. The Company shall not be obligated to effect more than two (2) such demand registrations pursuant
to this Section 3.03. 
 (d) Deferral. Notwithstanding the foregoing, if the Company shall furnish to Holders requesting
registration pursuant to this Section 3.03 a certificate signed by the President or Chief Executive Officer of the Company stating that in the good faith judgment of the Board, it would be seriously detrimental to the Company and its
shareholders for such registration statement to be 

  

 - 10 - 

 
filed at such time, then the Company shall have the right to defer such filing for a period of not more than 120 days after receipt of the request of the
Initiating Holders; provided, however, that the Company may not utilize this right more than once in any twelve (12) month period; provided further, that the Company shall not register any of its other securities
during such 120 day period. A demand right shall not be deemed to have been exercised until such deferred registration shall have been effected. 
 (e) Registration. The Company shall not be obligated to effect any such registration, qualification or compliance pursuant to this Section 3.03 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. 
 3.04
Piggyback Registrations. 
 (a) The Company shall notify all Holders in writing at least thirty (30) days prior to filing any
registration statement under the Securities Act for purposes of effecting a public offering of securities of the Company (including, but not limited to, registration statements relating to secondary offerings of securities of the Company, but
excluding registration statements relating to any employee benefit plan, corporate reorganization, exchange offer or offering of securities solely to the Company’s existing shareholders), and shall afford each such Holder an opportunity to
include in such registration statement all or any part of the Registrable Securities then held by such Holder. Each Holder desiring to include in any such registration statement all or any part of the Registrable Securities held by it shall within
twenty (20) days after receipt of the above-described notice from the Company, so notify the Company in writing, and in such notice shall inform the Company of the number of Registrable Securities such Holder wishes to include in such
registration statement. If a Holder decides not to include all of its Registrable Securities in any registration statement thereafter filed by the Company, such Holder shall nevertheless continue to have the right to include any Registrable
Securities in any subsequent registration statement or registration statements as may be filed pursuant to Sections 3.03, 3.04, or 3.05 by the Company with respect to offerings of its securities, all upon the terms and conditions set forth herein.

 (b) Underwriting. If a registration statement under which the Company gives notice under this Section 3.04 is for an
underwritten offering, then the Company shall so advise all Holders. In such event, the right of any Holder’s Registrable Securities to be included in a registration pursuant to this Section 3.04 shall be conditioned upon such
Holder’s participation in such underwriting and the inclusion of such Holder’s Registrable Securities in the underwriting to the extent provided herein. All Holders proposing to distribute their Registrable Securities through such
underwriting shall enter into an underwriting agreement in customary form with the managing underwriter or underwriters selected for such underwriting. Notwithstanding any other provision of this Agreement but subject to Section 3.13, if the
managing underwriter(s) determine(s) in good faith that marketing factors require a limitation of the number of shares to be underwritten, then the managing underwriter(s) may exclude shares from the registration and the underwriting,

and the Registrable Securities so included shall be apportioned pro rata among the selling Holders according to the total amount of Registrable Securities
owned by each selling Holder or in such other proportions as shall mutually be agreed to by all selling Holders; provided, however, that the right of the underwriter(s) to exclude shares (including Registrable Securities) from the
registration and underwriting as described in this Section 3.04(b) shall be restricted so that all shares that are not Registrable Securities, excluding Ordinary Shares issued by the Company in such underwriting and those Ordinary Shares
requested to be sold in such underwriting pursuant to a demand registration right exercised pursuant to the Second Registration Rights Agreement, but including Ordinary Shares and all other shares that are not Registrable Securities and are held by
any other person, including, without limitation, any person who is an employee, consultant, officer or director of the Company (or any Subsidiary of the Company) shall first be excluded in entirety from such registration and underwriting before any
Registrable Securities are so excluded; provided further, that in the first registered offering for the sale of the Company’s securities to the general public such allocations shall be made first, to the Company; second, to all
Combined Holders requesting inclusion of their respective Combined Registrable Securities in such registration statement on a pro rata basis based on the number of Combined Registrable Securities held by all such selling Combined Holders at the time
of filing the Registration Statement; and third, to any other shareholders of the Company requesting inclusion of their shares in the registration. If any Holder disapproves of the terms of any such underwriting, such Holder may elect to withdraw
therefrom by written notice to the Company and the underwriter(s), delivered at least ten (10) Business Days prior to the effective date of the registration statement. If, by the withdrawal of such Registrable Securities, a greater number of
Registrable Securities held by other Holders may be included in such registration (up to the limit imposed by the underwriters) the Company shall offer to all Holders who have included Registrable Securities in the registration the right to include
additional Registrable Securities in the same proportion used in determining the limitation as set forth above. Any Registrable Securities excluded or withdrawn from such underwriting shall be excluded and withdrawn from the registration.

 (c) Not Demand Registration. Registration pursuant to this Section 3.04 shall not be deemed to be a registration as described
in either Section 3.03 or Section 3.05. There shall be no limit on the number of times the Holders may request registration of Registrable Securities under this Section 3.04. 
 (d) Company’s Right to Terminate. At any time, the Company may terminate or withdraw any Registration Statement referred to in this
Section 3.04, and without any obligation to any such Holder whether or not any Holder has elected to include Registrable Shares in such registration. The Company may suspend the effectiveness and use of any Registration Statement at any
time for an unlimited amount of time whether or not any Holder has elected to include Registrable Shares in such registration. 
 (e)
Registration Rights For Holders of Ordinary Shares. The Company may permit any other holder of Ordinary Shares to register all or a portion of the Ordinary Shares held by such holder pursuant to a registration statement filed by the Company
in 

  

 - 12 - 

 
accordance with this Section 3.04; provided that such holder executes and delivers to the Company an agreement to be bound by the restrictions
and limitations hereof related to such registration; provided further that, if the managing underwriter(s) limits the number of Registrable Securities to be included in such registration pursuant to Section 3.04(b), then all
Ordinary Shares held by such holders (except Mandra, in the event it is granted demand registration rights by the Company) shall be excluded from such registration first before any Registrable Securities held by any Holders are excluded from such
registration. 
 3.05 Form F-3 Registration. In case that the Company shall receive from Holders of at least 25% of all Registrable
Securities Then Outstanding 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 Holder or Holders,
then the Company shall: 
 (a) Notice. Promptly give written notice of the proposed registration and the Holder’s or Holders’
request therefor, and any related qualification or compliance, to all other Holders; and 
 (b) Registration. As soon as practicable,
use commercially reasonable efforts to 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 Holder’s or
Holders’ Registrable Securities as are specified in such request, together with all or such portion of the Registrable Securities of any other Holder or Holders joining in such request as are specified in a written request given within twenty
(20) days after the Company provides the notice contemplated by Section 3.05(a); provided, however, that the Company shall not be obligated to effect any such registration, qualification or compliance pursuant to this
Section 3.05: 
 (i) if Form F-3 is not available for such offering by the Holders; 
 (ii) if the Holders, together with the holders of any other securities of the Company entitled to inclusion in such registration, propose to sell
Registrable Securities and such other securities (if any) at an aggregate price to the public, net of Selling Expenses, of less than US$4,000,000; 
 (iii) if the Company shall furnish to the Holders a certificate signed by the President or Chief Executive Officer of the Company stating that in the good faith judgment of the Board of the Company, it would be materially 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 no more than once during any twelve (12) month
period for a period of not more than 120 days after receipt of the request of the Holder or Holders under this Section 3.05; provided that the Company shall not register any of its other shares during such 120 day period; 
  

 - 13 - 

 (iv) if the Company has twice, within the twelve (12) month period preceding the date of such request,
already effected a registration under the Securities Act other than registrations from which the Registrable Securities of Holders have been excluded (with respect: to all or any portion of the Registrable Securities the Holders requested be
included in such registration) pursuant to the provisions of Sections 3.03(b) and 3.04(b); or 
 (v) 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. 
 Subject to the foregoing, the Company shall file a Form F-3 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 the Holders. 
 (c) Not Demand Registration. Form F-3 registrations shall not be deemed to be demand
registrations as described in Section 3.03 above. Except as otherwise provided herein, there shall be no limit on the number of times the Holders may request registration of Registrable Securities under this Section 3.05. 
 (d) Underwriting. If a registration statement under which the Company gives notice under this Section 3.05 is for an underwritten offering,
the provisions of Section 3.03(b) shall apply to such underwritten offering. 
 3.06 Expenses. All Registration Expenses
incurred by the Holders in connection with any registration pursuant to Sections 3.03, 3.04 or 3.05 (but excluding Selling Expenses) shall be borne by the Company. Each Holder participating in a registration pursuant to Sections 3.03, 3.04 or 3.05
shall bear such Holder’s proportionate share (based on the total number of shares sold in such registration other than for the account of the Company) of all Selling Expenses and other amounts payable to underwriter(s) or brokers, in connection
with such offering by the Holders. Notwithstanding the foregoing, the Company shall not be required to pay for any expenses of any registration proceeding begun pursuant to Section 3.03 if the registration request is subsequently withdrawn at
the request of the Holders of a majority of the Registrable Securities to be registered, unless the Holders of a majority of the Registrable Securities Then Outstanding agree that such registration constitutes the use by the Holders of one (1)
demand registration pursuant to Section 3.03 (in which case such registration shall also constitute the use by all Holders of one (1) such demand registration); provided, however, that if at the time of such withdrawal, the
Holders have learned of a material adverse change in the condition, business, or prospects of the Company not known to the Holders at the time of their request for such registration and have withdrawn their request for registration with reasonable
promptness after learning of such material adverse change, then the Holders shall not be required to pay any of such expenses and such request for registration shall not constitute the use of one (1) demand registration pursuant to
Section 3.03. For the avoidance of doubt, once a Registration Statement has become effective in relation to a request for registration by a qualified number of Holders pursuant to Section 3.03, it shall constitute the use by the Holders of
one (1) demand registration counted toward the maximum number of demand registrations all Holders are entitled to under Section 3.03, regardless of whether the participating Holders have disposed of their Registrable Securities or not in
the distribution covered by such registration. 
  

 - 14 - 

 3.07 Notice of Proposed Transfer. The Holder of each certificate representing Registrable
Securities, by acceptance thereof, agrees to comply in all respects with the provisions of this Section 3.07. Each such Holder agrees not to make any disposition of all or any portion of any Registrable Securities unless and until: 

(a) There is in effect a registration statement under the Securities Act covering such proposed disposition and such disposition is made in accordance
with such registration statement; or 
 (b) (i) Such Holder shall have notified the Company of the proposed disposition and shall have
furnished the Company with a detailed statement of the circumstances surrounding the proposed disposition, and 
 (ii) If reasonably
requested by the Company, such Holder shall furnish the Company with an opinion of counsel, reasonably satisfactory to the Company that such disposition shall not require registration of such shares under the Securities Act. It is agreed, however,
that no such opinion will be required for Rule 144 or Rule 144A transactions, except in unusual circumstances. 
 3.08 Obligations of the
Company. Whenever required to effect the registration of any Registrable Securities under this Agreement, the Company shall, as expeditiously as reasonably possible: 
 (a) Registration Statement. Prepare and file with the SEC a registration statement with respect to such Registrable Securities and use its commercially reasonable efforts to cause such registration statement to
become effective, and, upon the request of the Holders of a majority of the Registrable Securities registered thereunder, keep such registration statement effective until the distribution contemplated in the registration statement has been
completed; provided, however, that in the case of any registration of Registrable Securities on Form F-3 which are intended to be offered on a continuous or delayed basis, such period shall be extended, if necessary, to keep the
registration statement effective until all such Registrable Securities are sold. 
 (b) Amendments and Supplements. 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. 
 (c) Prospectuses. Furnish to the Holders such number of copies
of a prospectus, including a preliminary prospectus, in conformity with the requirements of the Securities Act, and such other documents as the Holders may reasonably request in order to facilitate the disposition of the Registrable Securities owned
by such Holders that are included in such registration. 
  

 - 15 - 

 (d) Blue Sky. Use its 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 the Holders, 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, unless the Company is already subject to service in such jurisdiction and except as may be required
by the Securities Act. 
 (e) Underwriting. In the event of any underwritten public offering, enter into and perform its obligations
under an underwriting agreement in usual and customary form, with the managing underwriter(s) of such offering. Each Holder participating in such underwriting shall also enter into and perform its obligations under such an agreement. 
 (f) Notification. Notify each Holder of Registrable Securities covered by such registration statement at any time when a prospectus relating
thereto is required to be delivered under the Securities Act of (i) the issuance of any stop order by the SEC in respect of such registration statement, or (ii) the occurrence 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. 
 (g) Opinion and Comfort Letter. Furnish, at the request of any Holder requesting registration of
Registrable Securities, on the date that such Registrable Securities are delivered to the underwriter(s) for sale, if such securities are being sold through underwriters, or, if such securities are not being sold through underwriters, on the date
that the registration statement with respect to such securities becomes effective, (i) an opinion, dated as of such date, of the counsel representing the Company for the purposes of such registration, in form and substance as is customarily
given to underwriters in an underwritten public offering, addressed to the underwriters, if any, and to the Holders requesting registration of Registrable Securities and (ii) letters dated as of (x) the effective date of the registration
statement covering such Registrable Securities and (y) the closing date of the offering, from the independent certified public accountants of the Company, in form and substance as is customarily given by independent certified public accountants
to underwriters in an underwritten public offering, addressed to the underwriters, if any, and to the Holders requesting registration of Registrable Securities. 
 3.09 Furnish Information. It shall be a condition precedent to the obligations of the Company to take any action pursuant to Sections 3.03, 3.04 or 3.05 that the selling Holders shall furnish to the Company
such information regarding themselves, the Registrable Securities held by them and the intended method of disposition of such securities as shall be required to timely effect the Registration of their Registrable Securities. 
  

 - 16 - 

 3.10 Indemnification. In the event any Registrable Securities are included in a registration
statement under Sections 3.03, 3.04 or 3.05: 
 (a) By the Company. To the extent permitted by law, the Company will indemnify and hold
harmless each Holder, its partners, managers, shareholders, officers, directors, legal counsel, any underwriter (as defined in the Securities Act) for such Holder and each person, if any, who controls such Holder or underwriter within the meaning of
the Securities Act or the Exchange Act, against any losses, claims, damages, or liabilities (joint or several) (“Damages”) to which they may become subject under the Securities Act, the Exchange Act, or other applicable laws,
insofar as such Damages (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 United States federal or state securities law, or any rule or regulation promulgated under the Securities Act, the Exchange Act, or any United States federal or state
securities law in connection with the offering covered by such registration statement; 
 and the Company shall reimburse each such Holder, its partner,
managers, shareholders, officer, director, legal counsel, underwriter or controlling person for any legal or other expenses reasonably incurred by them, as such expenses are incurred, in connection with investigating or defending any such Damage (or
any action in respect thereof); provided, however, that the indemnity agreement contained in this subsection 3.10(a) shall not apply to amounts paid in settlement of any such Damage (or any action in respect thereof) if such settlement
is effected without the consent of the Company (which consent shall not be unreasonably withheld); provided further that the Company shall not be liable in any such case for any such Damage (or any action in respect thereof) to the
extent (and only to the extent) that it arises out of or is based upon a Violation which occurs in reliance upon and in conformity with written information furnished expressly for use in connection with such registration by such Holder, partner,
officer, director, legal counsel, underwriter or controlling person of such Holder; and provided further, that the foregoing indemnity agreement is subject to the condition that, insofar as it relates to any such untrue statement,
alleged untrue statement, omission or alleged omission made in a preliminary prospectus on file with the SEC at the time the registration statement becomes effective or in an amended prospectus filed with the SEC pursuant to Rule 424(b) (the
“Final Prospectus”), such indemnity shall not inure to the benefit of (i) any underwriter, if a copy of the Final Prospectus was not furnished to the person asserting the Damages at or prior to the time such action is required
by the Securities Act, and if the Final Prospectus would have cured the defect giving rise to the Damages or (ii) any Holder, if there is no underwriter and if a copy of the Final Prospectus was furnished to such Holder and was not subsequently
furnished by such Holder to the Person asserting the Damages at or prior to the time that such action is required by the Securities Act, if the Final Prospectus would have cured the defect giving rise to the Damages. 
  

 - 17 - 

 (b) By Selling Holders. To the extent permitted by law, each selling Holder shall, if Registrable
Securities held by such Holder are included in the securities as to which such registration qualifications or compliance is being effected, 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, any underwriter and any other Holder selling securities under such registration statement or any of such other Holder’s partners,
directors, officers, legal counsel, or any person who controls such Holder within the meaning of the Securities Act or the Exchange Act, against any Damages to which the Company or any such director, officer, legal counsel, controlling person,
underwriter or other such Holder, partner or director, officer or controlling person of such other Holder may become subject under the Securities Act, the Exchange Act or other applicable laws, insofar as such Damage (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 Holder expressly for use in connection with
such registration; and each such Holder wilt reimburse any legal or other expenses reasonably incurred by the Company or any such director, officer, controlling person, underwriter or other Holder, partner, officer, director or controlling person of
such other Holder in connection with investigating or defending any such Damage (or any action in respect thereof); provided, however, that the indemnity agreement contained in this subsection 3.10(b) shall not apply to amounts paid in
settlement of any such Damage (or any action in respect thereof) if such settlement is effected without the consent of the Holder (which consent shall not be unreasonably withheld); provided, further, that in no event shall any
indemnity under this Section 3.10(b) exceed the net proceeds received by such Holder in the registered offering out of which the applicable Violation arises; and provided, further, that the foregoing indemnity agreement is subject
to the condition that, insofar as it relates to any such untrue statement, alleged untrue statement, omission or alleged omission made in a preliminary prospectus on file with the SEC at the time the Registration Statement becomes effective or in
the Final Prospectus, such indemnity shall not inure to the benefit of (i) any underwriter, if a copy of the Final Prospectus was not furnished to the person asserting the Damages at or prior to the time such action is required by the
Securities Act, and if the Final Prospectus would have cured the defect giving rise to the Damages or (ii) any Holder, if there is no underwriter and if a copy of the Final Prospectus was furnished to such Holder and was not subsequently
furnished by such Holder to the person asserting the Damages at or prior to the time that such action is required by the Securities Act, if the Final Prospectus would have cured the defect giving rise to the Damages. 
 (c) Notice. Promptly after receipt by an indemnified party under this Section 3.10 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 3.10, 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 

  

 - 18 - 

 
indemnifying party similarly noticed, to assume the defense thereof with counsel mutually satisfactory to the parties; provided, however, that
an indemnified party shall have the right to retain its own 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 conflict of 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 shall relieve such indemnifying party of liability to the indemnified party under this Section 3.10 to the extent the indemnifying party is prejudiced as a result thereof, but the omission to so
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 3.10. 
 (d) Contribution. In order to provide for just and equitable contribution to joint liability under the Securities Act in any case in which either
(i) any indemnified party makes a claim for indemnification pursuant to this Section 3.10 but it is judicially determined (by the entry of a final judgment or decree by a court of competent jurisdiction and the expiration of time to appeal
or the denial of the last right of appeal) that such indemnification may not be enforced in such case notwithstanding the fact that this Section 3.10 provides for indemnification in such case, then the indemnifying party, in lieu of
indemnifying such indemnified party thereunder, 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 hand in connection with the statements or omissions which resulted in such loss, liability, claim, damage or expense as well as any other relevant equitable
considerations. The relevant fault of the indemnifying party and 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; provided,
however, that, in any such case: (A) no Holder will be required to contribute any amount in excess of the net proceeds to such Holder from the sale of all such Registrable Securities offered and sold by such Holder pursuant to such
registration statement (less the aggregate amount of any damages which the Holder has otherwise been required to pay in respect of such loss, claim, damage, liability or action or any substantially similar loss, claim, damage, liability or action
arising from the sale of such Registrable Securities); and (B) no person or entity guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) will be entitled to contribution from any person or
entity who was not guilty of such fraudulent misrepresentation. 
 (e) Survival; Consents to Judgments and Settlements. The
obligations of the Company and Holders under this Section 3.10 shall survive the completion of any offering of Registrable Securities in a registration statement, regardless of the expiration of any statutes of limitation or extensions of such
statutes. No indemnifying party, in the defense of any such claim or litigation, shall, except with the consent of each indemnified party, consent to entry of any judgment or enter into any settlement which does not include as an unconditional term
thereof the giving by the claimant or plaintiff to such indemnified party of a release from all liability in respect to such claim or litigation. 
  

 - 19 - 

 (f) Underwriting Agreement. Notwithstanding the foregoing, to the extent that the provisions on
indemnification contained in the underwriting agreements entered into among the selling Holders, the Company and the underwriters in connection with the underwritten public offering are in conflict with the foregoing provisions, the provisions in
the underwriting agreement shall be controlling as to the Registrable Securities included in the public offering; provided, however, that if, as a result of this Section (f), any Holder, its officers, directors, and partners and any
person controlling such Holder is held liable for an amount which exceeds the aggregate proceeds received by such Holder from the sale of Registrable Securities included in a registration, as provided in (b) above, pursuant to such underwriting
agreement (the “Excess Liability”), the Company shall reimburse such Holder for such Excess Liability. 
 3.11 Termination of
the Company’s Obligations. The Company shall have no obligations pursuant to Sections 3.03, 3.04 and 3.05 with respect to any Registrable Securities proposed to be sold by a Holder in a registration pursuant to Section 3.03, 3.04 or
3.05 if, in the reasonable opinion of counsel to the Company, all Registrable Securities may then be sold without registration pursuant to Rule 144 promulgated under the Securities Act. In any event, the rights under Sections 3.03, 3.04 and 3.05
shall terminate on the later of (i) two years after a Qualified IPO or (ii) four years after the date hereof. 
 3.12 No Superior
Registration Rights to Third Parties. Without the prior written consent of the Investors (which consent not to be unreasonably withheld), the Company shall not grant, or cause or permit to be created, for the benefit of any person or entity
registration rights superior to those granted to the Holders herein relating to any securities of the Company. 
 3.13 Lockup. Each
Holder agrees that, upon request by the underwriters managing the initial public offering of the Company’s securities, such Holder will enter into a customary lockup agreement with the underwriters under which such Holder (individually the
“Lockup Shareholder”, and collectively, the “Lockup Shareholders”) shall agree, without the prior written consent of the Company or such underwriters, not to sell or otherwise transfer or dispose of any Purchased
Shares (other than those permitted to be included in the registration and other transfers to Affiliates permitted by law) for a period of time specified by such underwriters no greater than 180 days from the effective date of the registration
statement covering such initial public offering or the pricing date of such offering as may be requested by the underwriters, provided that each of the directors, officers and other holders of Ordinary Shares of the Company signs
substantially identical lockup agreements. Notwithstanding the foregoing, (i) each Lockup Shareholder shall be released from the lockup to the extent that any other locked-up shareholders of the Company are released; and (ii) each Lockup
Shareholder may engage in private transfers of the securities to Affiliates, provided such Affiliates enter into the same lockup agreement with such underwriters or agree in writing to be bound by the lockup agreements signed between the
Lockup Shareholders and the underwriters. As used in this Agreement, “Affiliate” or “Affiliates” shall have the meaning given in Rule 405 promulgated under the Securities Act. 
  

 - 20 - 

 3.14 Rule 144 Reporting. With a view to malting available to the Holders the benefits of certain
rules and regulations of the SEC which may at any time permit the sale of the Registrable Securities to the public without registration or pursuant to a registration on Form F-3, after such time as a public market exists for the Ordinary Shares, the
Company agrees to: 
 (a) Make and keep public information available, as those terms are understood and defined in Rule 144 under the
Securities Act, at all times after the effective date of the first registration under the Securities Act filed by the Company for an offering of its securities to the general public; 
 (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 (at any
time after it has become subject to such reporting requirements); and 
 (c) So long as a Holder owns any Registrable Securities, to furnish
to such Holder forthwith upon request a written statement by the Company as to its compliance with the reporting requirements of Rule 144 (at any time after ninety (90) days after the effective date of the Company’s initial public
offering), the Securities Act and the Exchange Act (at any time after it has become subject to such reporting requirements), or its qualification as a registrant whose securities may be resold pursuant to Form F-3 (at any time after it so
qualifies). 
 3.15 Re-sale Rights. The Company shall use its best efforts to assist each Holder in the sale or disposition of its
Registrable Securities after an initial public offering, including the prompt delivery of applicable instruction letters by the Company and legal opinions from the Company’s counsels in forms reasonably satisfactory to the Holder’s
counsel. In the event the Company has depositary receipts listed or traded on any stock exchange or inter-dealer quotation system, the Company shall pay all costs and fees related to such depositary facility, including initial deposit, conversion
fees and maintenance fees for Registrable Securities held by the Holders. 
 ARTICLE IV 
 PREEMPTIVE RIGHT TO NEW SHARES 
 4.01 Preemptive Right. Subject to the terms and conditions specified in this Article IV, the Company hereby grants to the Investors a preemptive right with respect to future issues by the Company of its New Shares (as hereinafter
defined). Each time the Company proposes to offer any shares of, or securities convertible into or exchangeable or exercisable for any shares of, any class of its share capital (“New Shares”), the Company shall first make an
offering of such New Shares to the Investors in accordance with the following provisions: 
 (a) The Company shall deliver a notice to the
Investors stating (i) its bona fide intention to offer such New Shares, (ii) the number of such New Shares to be offered, and (iii) the price and terms upon which it proposes to offer such New Shares. 
  

 - 21 - 

 (b) By written notification to the Company, within twenty (20) Business Days after receipt of the
notice contemplated by Section 4.01(a), each Investor may elect to subscribe for, at the price and on the terms specified in the notice, a portion of such New Shares that equals the proportion that the number of Ordinary Shares then issued and
held by such Investor, or issuable upon conversion of Series A Shares then held by such Investor, bears to the total number of Ordinary Shares of the Company then issued and held, or issuable upon conversion of Series A Shares then held by the
Investors. 
 (c) If all New Shares that the Investors are entitled to subscribe pursuant to Section 4.01(b) are not elected to be
subscribed for as provided in Section 4.01(b) hereof, the Company may, during the ninety (90) day period following the expiration of the period provided in Section 4.01(b) hereof, offer the remaining unsubscribed portion of such New
Shares to any person or persons at a price not less than, and upon terms no more favorable to the offeree than those specified in the Notice. If the Company does not enter into an agreement for the subscription of such remaining unsubscribed portion
of the New Shares within such period, or if such agreement is not consummated within ninety (90) days of the execution thereof, the right provided hereunder shall be deemed to be revived and such portion of New Shares shall not be offered
unless first re-offered to Investors in accordance herewith. 
 (d) The preemptive rights of the Investors set forth under this
Section 4.01 shall not apply to the Company’s sale of certain floating rate secured convertible bonds due 2009 convertible into Ordinary Shares of the Company within three (3) months after the Closing. 
 4.02 New Shares. For purposes of this Article IV, “New Shares” shall not include, and therefore the preemptive rights shall not
be applicable to the issuance of, any of the following securities of the Company: 
 (a) Ordinary Shares issued or issuable upon conversion of
Series A Shares or upon the exercise or conversion of any Convertible Securities (as defined in the Restated Articles) or any options or warrants outstanding as of the date hereof; 
 (b) Not more than 50,000 Ordinary Shares (as adjusted for any share dividends, combinations, splits, recapitalization and including any such shares which
are repurchased) issuable or issued to Employees (as defined below) pursuant options issued under the Share Option Plan (as defined below) which in any event shall represent not more than 5% of the Company’s share capital on a fully diluted
basis; 
 (c) any share split, share dividend, distribution, recapitalization, reclassification or similar transaction for which proportional
adjustments are made; 
  

 - 22 - 

 (d) Ordinary Shares or other equity securities directly or indirectly convertible into or exchangeable
for Ordinary Shares issued in a bona fide acquisition, merger, consolidation, strategic alliance, license of technology or similar business combination or strategic transaction, the terms of which are approved by the Board; and 
 (e) Ordinary Shares issued in an underwritten public offering. 
 4.03 Termination of Rights. The preemptive right as provided in this Article IV shall terminate and cease to be in effect upon the closing of a Qualified IPO. 
 ARTICLE V 
 ASSIGNMENT AND AMENDMENT

 5.01 Assignment. 
 (a) Notwithstanding anything herein to the contrary, the rights of any Investor hereunder may be assigned (but only with all related obligations including those obligations intended to ensure compliance with the provisions of the Securities
Act) to any transferee or assignee of such Investor, provided, in each case, that: (i) 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 rights are being assigned; (ii) such transferee or assignee agrees in writing to be bound by and subject to all the terms and conditions of this Agreement, (iii) such transfer is permitted by and
complies with the terms of this Agreement, and (iv) such transferee or assignee is not a “Competitor” of the Company, as such term is defined in the Share Purchase Agreement. 
 (b) Legend. Each existing or replacement certificate for any shares now owned or hereafter acquired by a Holder and each certificate issued to any
person in connection with a transfer may bear the following legend (or a substantially similar legend): 
 “THE SHARES REPRESENTED BY
THIS CERTIFICATE WAVE BEEN ACQUIRED FOR INVESTMENT AND HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933. THESE SHARES MAY NOT BE SOLD OR TRANSFERRED IN THE ABSENCE OF SUCH REGISTRATION OR AN EXEMPTION THEREFROM UNDER SAID ACT. COPIES OF THE
AGREEMENTS COVERING THE PURCHASE OF THESE SHARES AND THE RIGHTS TO REGISTER THESE SHARES AND RESTRICTING THEIR TRANSFER MAY BE OBTAINED UPON WRITTEN REQUEST TO THE SECRETARY OF THE COMPANY.” 
 Each Holder agrees that the Company may instruct its transfer agent to impose transfer restrictions on the shares represented by certificates bearing the legend referred
to above to enforce the provisions of this Agreement.

 ARTICLE VI 
 BOARD OF DIRECTORS AND PROTECTIVE PROVISIONS 
 6.01 Election of Directors. 
 (a) So
long as an Investor continues to hold any Purchased Shares or Ordinary Shares issued upon conversion of the Purchased Shares (and with respect to TB, including for so long as it continues to hold any TB Ordinary Shares), each Investor shall be
entitled to designate one (1) director to be on the Board (collectively, the “Investor Directors”), and Genius shall (i) take all action necessary to elect such candidate designated by the Investors as directors, and
(ii) not increase the number of directors on the Board to be more than five (5) directors. The Investor Director designated by TB shall initially be Shujun Li and the Investor Director designated by Balderton shall initially be vacant.

 (b) The Investor Directors shall be entitled to appoint alternates to serve at any meeting of the Board or of any committee thereto, and
such alternates shall be permitted to attend all meetings of the Board or of any committee and vote on the relevant Investor Director’s behalf. 
 (c) Whenever a candidate for appointment to the Board is to be designated by a group of shareholders, if shares are held and voted by such shareholders in such proportion that no majority vote is obtained, then the
candidates with the greatest number of votes shall be deemed designated (up to the number of candidates to be selected by such group of shareholders). The candidate(s) so designated shall be the designated candidate(s) for that group of shareholders
and the shareholders agree to vote for such individuals. No director shall be removed except by the affirmative vote of the group of shareholders entitled to designate such director, and no director may be so removed if the votes cast against such
director’s removal would be sufficient (assuming that each of such group’s designated directors were being chosen) to designate such director for such group of shareholders, other than a removal for Cause (as defined below) of such
director, which removal may be effected pursuant to an ordinary resolution. “Cause” means (a) a director’s willful or continued failure to substantially perform his or her duties, (b) such director’s conviction
or under formal investigation in a criminal proceeding (other than traffic violations or other minor infractions), (c) such director’s being censured or subject to equivalent action by any internationally recognized securities exchange, or
(d) such director being subject to a bankruptcy event. 
 (d) An appointment of a director may be on terms that the director shall
automatically retire from office (unless he has sooner vacated office) at the next or a subsequent annual general meeting or upon any specified event or after any specified period; but no such term shall be implied in the absence of express
provision. 
  

 - 24 - 

 (e) There shall be no shareholding qualification for directors. 
 6.02 Board Meeting. The Board shall meet at least once per quarter. 
 6.03 Expenses. The Company shall reimburse the Investor Directors for all reasonable expenses relating to all Board activities, including,
without limitation, expenses or fees incurred in relation to attending the Board meetings or meetings of any committee. The Company shall also provide customary director insurance coverage for, and indemnification of, the Investor Directors.

 6.04 Acts Requiring Consent of Investor Directors. In addition to such other limitations as may be provided in each Group
Company’s constitutional documents, the following acts of any of the Group Companies (whether by amendment of such Group Company’s Memorandum or Articles of Association or otherwise, and whether in a single transaction or a series of
related transactions) shall require the consent of each Investor Director: 
 (a) Authorize, create, issue or sell (by reclassification or
otherwise) any shares of any class or equity interests or securities convertible into shares or other equity interests in any Group Company, except for the issuance of any securities that are specifically excluded from the definition of “New
Shares” as set forth in Section 4.02 above; 
 (b) Amend or waive any material provision of the Company’s Restated
Articles or any of the charter documents of any Group Company; 
 (c) Authorize any action that results in the redemption or repurchase of
any equity security of any Group Company; 
 (d) Sell or dispose of the whole or a substantial part of the business, goodwill or the assets
of any Group Company; 
 (e) Pass any resolution approving liquidation, dissolution or winding up or the initiation of bankruptcy proceedings
or apply for the appointment of a receiver, judicial manager or like officer in relation to any Group Company; 
 (f) Undertake any merger,
acquisition, consolidation, or reorganization of any Group Company; 
 (g) Effect a recapitalization, reclassification, split-off, or
spin-off of any Group Company; 
 (h) Engage in any business materially different from that described in the then current business plan of
any Group Company, change the name of any Group Company or cease any business undertaking of any Group Company; 
  

 - 25 - 

 (i) Engage or enter into any transaction or agreement with any Group Company’s Affiliates,
shareholders or other related parties; 
 (j) Approve or amend the Share Option Plan (as defined below); and 
 (k) Change materially the accounting methods or policies or appoint or change the auditors of any Group Company. 
 6.05 Termination. Notwithstanding any other provisions herein to the contrary, the rights granted to the Investors as provided in this Article VI
shall terminate and cease to be in effect upon the closing of a Qualified IPO. 
 ARTICLE VII 
 EMPLOYEE SHARE OPTION PLAN 
 7.01
Grant of Share Options. The Company represents and acknowledges that the Company has reserved fifty thousand (50,000) Ordinary Shares for the Company’s stock option pool and has established a bona fide employment-related share purchase
or option plan (the “Share Option Plan”) pursuant to which the Company may grant options, warrants or other rights (“Options”) to its employees, officers, directors, advisors or consultants (collectively,
“Employees” and individually, an “Employee”) to subscribe for up to fifty thousand (50,000) Ordinary Shares (subject to adjustment for any share dividends, combinations, splits, recapitalization and including
any such share which are repurchased), which in no event shall represent more than 5% of the Company’s share capital on a fully diluted basis, with each Option bearing an exercise price not less than the fair market value of an Ordinary Share
of the Company on its date of grant. For the determination of “fair market value” of the Ordinary Shares, if no agreement is reached by the Company and the Investors, the parties shall jointly appoint a “Big 4” accounting firm to
assess the fair market value of the Ordinary Shares, which assessment should be final and binding on the parties hereto. 
 7.02 Share
Option Vesting. Except as expressly otherwise approved by the Board and subject to the prior written consent of the Investors, options granted to the Employees after the Closing Date (as defined in the Share Purchase Agreement) pursuant to the
Share Option Plan shall be vested in equal annual installments during a no less than four-year vesting period, starting on the first anniversary of the employment commencement date of the relevant Employee.

schedules and exhibits attached hereto and thereto) constitute the entire agreement between the parties hereto with respect to the subject matter hereof and thereof; provided, however, that subjection to Section 8.01 above,
nothing in this Agreement or other Transaction Agreements shall be deemed to terminate or supersede the provisions of (i) that certain anti-dilution, co-sale and put option agreement and that certain share charge, both entered into by and

 8.06 Severability. If any provision of this Agreement is found to be invalid or unenforceable,
then such provision shall be construed, to the extent feasible, so as to render the provision enforceable and to provide for the consummation of the transactions contemplated hereby on substantially the same terms as originally set forth herein, and
if no feasible interpretation would save such provision, it shall be severed from the remainder of this Agreement, which shall remain in full force and effect unless the severed provision is essential to the rights or benefits intended by the
