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 

  

 - 9 - 








 
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 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. 
  

 - 10 - 








 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

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 by Mandra in such underwriting pursuant to its demand registration right (if any), 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. 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 

  

 - 11 - 








 
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.

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 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

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; 
 (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. 
  

 - 13 - 








 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. 
 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. 
  

 - 14 - 








 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. 
 (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. 
  

 - 15 - 








 (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. 
 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; 
  

 - 16 - 








 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. 
 (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 will 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, 

  

 - 17 - 








 
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 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 

  

 - 18 - 








 
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. 
 (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. 
  

 - 19 - 








 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. 
 3.14 Rule 144
Reporting. With a view to making 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). 
  

 - 20 - 








 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. 
 (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 4.0l(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 4.0l(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. 
  

 - 21 - 








 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; 
 (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. 
  

 - 22 - 








 (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 HAVE 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. 
 5.02 Amendment of Rights. Any term
of this Agreement may be amended only with the written consent of the parties hereof. Any amendment or waiver effected in accordance with this Section 5.02 shall be binding upon all parties hereto and their respective assigns. 
 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 

  

 - 23 - 








 
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. 
 (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

 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.
