have (i) the right to inspect facilities, records and books of the Group Companies at any time during regular working hours upon reasonable prior notice to the Company, (ii) the right to discuss the business, operations and conditions of
the Group Companies with their respective directors, officers, employees, accountants, legal counsel, financial advisors, and investment bankers, and (iii) the right to dispatch auditing personnel of its own or hire independent auditors to

auditor shall bear the cost of such auditor. Notwithstanding the foregoing, the Company or any of the Group Companies shall not be obligated pursuant to this Section 1.1(b) to provide access to (x) any information that
it reasonably and in good faith considers to be a trade secret and the disclosure of which would adversely affect the interest of the Group Companies, (y) any confidential information unless covered by an enforceable confidentiality agreement,
in form reasonably acceptable to the Company, or (z) any information the disclosure of which would adversely affect the attorney-client privilege between the Company and its counsel.

all reasonable out-of-pocket expenses incurred in connection with attending any meetings of the Board and any committee thereof. Notwithstanding the foregoing, if a
majority of the Series A Directors or the Series B Director is not present at such adjourned meeting, no resolution may be adopted at such adjourned meeting with respect to the matters set forth in Section 7.22(A) or

Section 2.3; provided 

  
 7 













 
that the Company shall not be obligated to effect any such registration if the Company has, within the six (6) month period preceding the date of such request, already effected a
registration under the Securities Act pursuant to this Section 2.3 or Section 2.5 or in which the Holders had an opportunity to participate pursuant to the provisions of
Section 2.4, 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

counted as “effected” for purposes of this Section 2.3(a) until such time as the applicable registration statement has been declared effective by the SEC, unless the Initiating Holders (as defined below) withdraw
their request for such registration, elect not to pay the registration expenses therefor, and forfeit their right to one demand registration statement pursuant to Section 2.6, in which case such withdrawn registration
statement shall be counted as “effected” for purposes of this Section 2.3(a). For purposes of this Agreement, reference to registration of securities under the Securities Act and the Exchange Act shall be deemed
to mean the equivalent registration in a jurisdiction other than the United States as designated by such Holders, it being understood and agreed that in each such case all references in this Agreement to the Securities Act, the Exchange Act and
rules, forms of registration statements and registration of securities thereunder, U.S. law and the SEC, shall be deemed to refer, to the equivalent statutes, rules, forms of registration statements, registration of securities and laws of and
equivalent government authority in the applicable non-U.S. jurisdiction. 
 (b) Underwriting.
If the Holders initiating the registration request under this Section 2.3 (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 2.3 and the Company shall include such information in the Request Notice. In such event, the right of any Holder to include its
Registrable Securities in such registration shall be conditioned upon such Holder’s participation in such underwriting and the inclusion of such Holder’s Registrable Securities in the underwriting (unless otherwise mutually agreed by a
majority in interest of the Initiating Holders and such Holder) to the extent provided herein. All Holders proposing to distribute their 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 Holders of a majority of the Registrable Securities being registered and reasonably acceptable to the Company. Notwithstanding any other provision of this
Section 2.3, if the underwriter(s) advise(s) the Company in writing that marketing factors require a limitation of the number of securities to be underwritten, then the Company shall so advise all Holders of Registrable
Securities 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 of
Registrable Securities 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 number of shares
of Registrable Securities to be included in such underwriting and registration shall not be reduced unless all other securities are first entirely excluded from the underwriting and registration including, without limitation, all shares that are not
Registrable Securities and are held by any other person, including, without limitation, any person who is an employee, officer or director of the Company or any Subsidiary of the Company; provided further, that at least twenty-five
percent (25%) of Registrable Securities requested by the Holders to be included in such underwriting and registration shall be so included. 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. Any Registrable Securities excluded or withdrawn from such underwriting shall be
excluded and withdrawn from the registration.

 2.4 Piggyback Registrations. 

(a) The Company shall notify all Holders of Registrable Securities 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 or a corporate reorganization), 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 by the
Company with respect to offerings of its securities, all upon the terms and conditions set forth herein. No Holder of Registrable Securities shall be granted piggyback registration rights superior to those of the Holders of the Preferred Shares
without the consent in writing of the Holders of at least fifty percent (50%) of the Registrable Securities. 
 (b) Underwriting. If a
registration statement under which the Company gives notice under this Section 2.4 is for an underwritten offering, then the Company shall so advise the Holders of Registrable Securities. In such event, the right of any
such Holder’s Registrable Securities to be included in a registration pursuant to this Section 2.4 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 2.13, 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 number of shares that may be included in the registration and the underwriting
shall be allocated, first, to the Company, second, to each of the Holders requesting inclusion of their Registrable Securities in such registration statement on a pro rata basis based on the total number of shares of Registrable
Securities then held by each such Holder, and third, to holders of other securities of the Company; provided, however, that the right of the underwriter(s) to exclude shares (including Registrable Securities) from the
registration and underwriting as described above shall be restricted so that (i) the number of Registrable Securities included in any such registration is not reduced below twenty percent (20%) of the aggregate number of shares of Registrable
Securities for which inclusion has been requested; and (ii) all shares that are not Registrable Securities and are held by any other person, including, without limitation, any person who is an employee, officer or director of the Company (or
any subsidiary of the 

  
 9 













 
Company) shall first be excluded 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. 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 2.4 shall not be deemed to be a demand registration as described in Section 2.3 above. There shall be no limit on the number of times the Holders may request registration
of Registrable Securities under this Section 2.4. 
 2.5 Form F-3.
If at any time when it is eligible to use a Form F-3 registration statement the Company shall receive from the Holders of at least thirty percent (30%) of the 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 will: 
 (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 of Registrable Securities; and 
 (b)
Registration. As soon as practicable, effect such registration and all such qualifications and compliances as may be so requested and as would permit or facilitate the sale and distribution of all or such portion of such Holders 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 2.5(a); provided, however, that the Company shall not be obligated to effect any such registration, qualification or compliance
pursuant to this Section 2.5: 
 (i) 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 of less than US$5,000,000; 

(ii) 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, 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 sixty (60) days after receipt of the request
of the Holder or Holders under this Section 2.5; provided that the Company shall not register any of its other shares during such sixty (60) day period; A registration right under this
Section 2.5 shall not be deemed to have been exercised until such deferred registration shall have been effected; 

(iii) if the Company has, within the twelve (12) month period preceding the date of such request, already effected one
(1) registration on Form F-3; 

  
 10 













 (iv) if the Company has, within the twelve (12) month period preceding the date of
such request, already effected two (2) registrations under the Securities Act other than a registration 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 2.3(b) and 2.4(a); 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 2.3 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 2.5. 

2.6 Expenses. All Registration Expenses incurred in connection with any registration pursuant to Sections 2.3, 2.4 or
2.5 (but excluding Selling Expenses) shall be borne by the Company. Each Holder participating in a registration pursuant to Sections 2.3, 2.4 or 2.5 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 or 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 2.3 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 2.3; provided further, 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 registration shall not constitute the use of a demand registration pursuant to Section 2.3. 

2.7 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 best 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 for a period of up to ninety (90) days or, in the case of Registrable Securities registered under Form F-3 in accordance with Rule 415 under the Securities Act or a
successor rule, until the distribution contemplated in the registration statement has been completed; provided, however, that (i) such ninety (90) day period shall be extended for a period of time equal to the period any
Holder refrains from selling any securities included in such registration at the request of the underwriter(s), and (ii) 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 ninety (90) day period shall be extended, if necessary, to keep the registration statement effective until all such Registrable Securities are sold. 

  
 11 













 (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 they may reasonably request in order to facilitate the disposition of the Registrable Securities owned by them that are included in such
registration. 
 (d) Blue Sky. Use its best 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 happening of any event as a result of which the prospectus
included in such registration statement, as then in effect, includes an untrue statement of a material fact or omits to state a material fact required to be stated therein or necessary to make the statements therein not misleading in the light of
the circumstances then existing. 
 (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 and reasonably satisfactory to a majority in interest of the Holders requesting registration, 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 and reasonably satisfactory to a majority in interest of the Holders requesting registration,
addressed to the underwriters, if any, and to the Holders requesting registration of Registrable Securities. 

  
 12 













 2.8 Furnish Information. It shall be a condition precedent to the obligations of the
Company to take any action pursuant to Sections 2.3, 2.4 or 2.5 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. 
 2.9
Indemnification. In the event any Registrable Securities are included in a registration statement under Sections 2.3, 2.4 or 2.5: 

(a) By the Company. To the extent permitted by law and the Restated Articles, the Company will indemnify and hold harmless each Holder,
its partners, 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) to which they may become subject under the Securities Act, the Exchange Act, or other United States federal or state law, insofar as such losses, claims, damages, or liabilities
(or actions in respect thereof) arise out of or are based upon any of the following statements, omissions or violations (collectively a “Violation”): 

(i) any untrue statement or alleged untrue statement of a material fact contained in such registration statement, including any preliminary
prospectus or final prospectus contained therein or any amendments or supplements thereto; 
 (ii) the omission or alleged omission to state
therein a material fact required to be stated therein, or necessary to make the statements therein not misleading; or 
 (iii) any violation
or alleged violation by the Company of the Securities Act, the Exchange Act, any 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 will reimburse each such Holder, its partner,
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 loss, claim, damage, liability or
action; provided, however, that the indemnity agreement contained in this subsection 2.9(a) shall not apply to amounts paid in settlement of any such loss, claim, damage, liability or action if such settlement is effected without the
consent of the Company (which consent shall not be unreasonably withheld), nor shall the Company be liable in any such case for any such loss, claim, damage, liability or action to the extent that it arises out of or is based upon a Violation 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. 

  
 13 













 (b) By Selling Holders. To the extent permitted by law, each selling Holder will, if
Registrable Securities held by 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 losses, claims, damages or liabilities (joint or several) 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 United States
federal or state law, insofar as such losses, claims, damages or liabilities (or actions in respect thereto) arise out of or are based upon any Violation, in each case to the extent (and only to the extent) that such Violation occurs in reliance
upon and in conformity with written information furnished by such 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 loss, claim, damage, liability or action; provided,
however, that the indemnity agreement contained in this subsection 2.9(b) shall not apply to amounts paid in settlement of any such loss, claim, damage, liability or action if such settlement is effected without the consent of the Holder,
which consent shall not be unreasonably withheld; and provided, further, that in no event shall any indemnity under this Section 2.9(b) together with any amount contributed pursuant to
Section 2.9(d) below exceed the net proceeds (net of any Selling Expenses paid by such Holder) received by such Holder in the registered offering out of which the applicable Violation arises, except in the case of willful
misconduct or fraud by such Holder. 
 (c) Notice. Promptly after receipt by an indemnified party under this
Section 2.9 of notice of the commencement of any action (including any governmental action), such indemnified party will, if a claim in respect thereof is to be made against any indemnifying party under this
Section 2.9, 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 2.9 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 2.9. 
 (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 2.9 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 2.9 provides for indemnification in such case, or (ii) contribution under the Securities Act may be required on the part of
any indemnified party in circumstances for which indemnification is provided under 

  
 14 













 
this Section 2.9; then, and in each such case, the indemnified party and the indemnifying party will contribute to the aggregate losses, claims, damages or liabilities
to which they may be subject (after contribution from others) in such proportion so that a Holder (together with its related persons) is responsible for the portion represented by the percentage that the public offering price of its Registrable
Securities offered by and sold under the registration statement bears to the public offering price of all securities offered by and sold under such registration statement, and the Company and other selling Holders are responsible for the remaining
portion. The relative fault of the indemnifying party and of the indemnified party shall be determined by a court of law 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; 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 2.9 shall survive until the fifth (5th) anniversary of 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. 

2.10 No Registration Rights to Third Parties. Without the prior written consent of the holders of at least sixty percent (60%) of the
Registrable Securities then outstanding, the Company covenants and agrees that it shall not grant, or cause or permit to be created, for the benefit of any person or entity any registration rights of any kind (whether similar to the demand,
“piggyback” or Form F-3 registration rights described in this Section 2, or otherwise) relating to any securities of the Company which are senior to, or on a parity with,
those granted to the Holders of Registrable Securities. 
 2.11 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 

  
 15 













 (c) So long as a Holder owns any Registrable Securities, to furnish to such Holder forthwith
upon request (i) 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), (ii) a copy of the most recent annual or quarterly report of the Company, and (iii) such other reports and documents of the Company as a Holder may reasonably request in availing itself of any rule or regulation of
the SEC that permits the selling of any such securities without registration or pursuant to Form F-3. 

2.12 Market Stand-Off. Each Party agrees that, so long as it holds any voting securities of the
Company, upon request by the Company or the underwriters managing the initial public offering of the Company’s securities, it will not sell or otherwise transfer or dispose of any securities of the Company held immediately before the
effective date of the registration statement for such offering (other than those permitted to be included in the registration and other transfers to Affiliates permitted by law) without the prior written consent of the Company or such underwriters,
as the case may be, for a period of time specified by the representative of the underwriters not to exceed 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. The Company shall use commercially reasonable efforts to take all steps to shorten such lock-up period. The foregoing provision of this
Section 2.12 shall not apply to the sale of any securities of the Company to an underwriter pursuant to any underwriting agreement, and shall only be applicable to the Holders if all shareholders owning more than five
percent (5%) of the Company’s outstanding Ordinary Shares (on an as-converted basis) are subject to the same restrictions, and if the Company or any underwriter releases any other shareholder from his,
her or its sale restrictions so undertaken, then each Holder shall be notified prior to such release and shall itself be simultaneously released to the same proportional extent. The Company shall require all future acquirers of the Company’s
securities to execute prior to a Qualified Initial Public Offering a market stand-off agreement containing substantially similar provisions as those contained in this Section 2.12.

 2.13 Termination. The registration rights in this Section 2 shall terminate upon the earliest to occur of
(i) the closing of a Deemed Liquidation Event; (ii) such time as Rule 144 or another similar exemption under the Securities Act or other applicable securities laws is available for the sale of all of such Holder’s shares without
registration; or (iii) the third (3rd) anniversary of a firm-commitment underwritten initial public offering by the Company of its Ordinary Shares or a reverse merger of the Company with a
listed company, on a reputable securities exchange in the United States, Hong Kong or PRC (excluding the National Equities Exchange And Quotations of the PRC), or any other jurisdiction, including without limitations, the New York Stock Exchange or
the Nasdaq Global Market in the United States and the Main Board of the Hong Kong Stock Exchange (each, a “Recognized Exchange”), with a per share price of at least US$[***] (subject to adjustments for share dividends, splits,
combinations, recapitalization and similar events) and net proceeds to the Company of at least US$[***] (the “Qualified Initial Public Offering”).

 3. RIGHT OF PARTICIPATION. 

3.1 General. Each holder of Preferred Shares, including each holder of Preferred Shares to which rights under this
Section 3 have been duly assigned in accordance with Section 5 (hereinafter referred to as a “Participation Rights Holder”), shall have the preemptive right to purchase such
Participation Rights Holder’s Pro Rata Share (as defined below), of all (or any part) of any New Securities (as defined in Section 3.3) that the Company may from time to time issue after the date of this Agreement (the
“Right of Participation”). A Participation Rights Holder shall be entitled to apportion the Right of Participation hereby granted to it in such proportions as it deems appropriate, among (i) itself and (ii) its Affiliates;
provided that each such Affiliate (x) is not a Competitor, and (y) agrees to enter into this Agreement. 
 3.2 Pro Rata
Share. A Participation Rights Holder’s “Pro Rata Share” for purposes of the Right of Participation is the ratio of (a) the number of Ordinary Shares (calculated on a fully-diluted and
as-converted basis) held by such Participation Rights Holder, to (b) the total number of Ordinary Shares of the Company then outstanding (calculated on a fully-diluted and
as-converted basis) held by all the Participation Rights Holders immediately prior to the issuance of the New Securities giving rise to the Right of Participation. 

3.3 New Securities. “New Securities” shall mean any Preferred Shares, Ordinary Shares,
Non-voting Ordinary Shares or other voting shares of the Company and rights, options or warrants to purchase such Preferred Shares, Ordinary Shares, Non-voting Ordinary
Shares and securities of any type whatsoever that are, or may become, convertible or exchangeable into such Preferred Shares, Ordinary Shares, Non-voting Ordinary Shares or other voting shares,
provided, however, that the term “New Securities” shall not include the Exempted Securities (as defined in the Restated Articles). 

3.4 Procedures. 
 (a) First
Participation Notice. In the event that the Company proposes to undertake an issuance of New Securities (in a single transaction or a series of related transactions), it shall give to each Participation Rights Holder written notice of its
intention to issue New Securities (the “First Participation Notice”), describing the amount and type of New Securities, the price and the general terms upon which the Company proposes to issue such New Securities. Each Participation
Rights Holder shall have twenty (20) Business Days from the date of receipt of any such First Participation Notice (the “First Participation Period”) to agree in writing to purchase such Participation Rights Holder’s Pro
Rata Share of such New Securities for the price and upon the terms and conditions specified in the First Participation Notice by giving written notice to the Company and stating therein the quantity of New Securities to be purchased (not to exceed
such Participation Rights Holder’s Pro Rata Share). If any Participation Rights Holder fails to so agree in writing within such twenty (20) Business Days period to purchase such Participation Rights Holder’s full Pro Rata Share of an
offering of New Securities, then such Participation Rights Holder shall forfeit the right hereunder to purchase that part of its Pro Rata Share of such New Securities that it did not agree to purchase. 

(b) Second Participation Notice; Oversubscription. If any Participating Rights Holder fails or declines to exercise its Right of
Participation in accordance with subsection (a) above, the Company shall promptly give notice (the “Second Participation Notice”) to other Participating Rights Holders who exercised their Right of Participation (the
“Right Participants”) in accordance with subsection (a) above. Each Right Participant shall have ten (10) Business Days from the date of receipt of the Second Participation Notice (the “Second Participation
Period”) to notify the Company of its desire to purchase more than its Pro Rata Share of the New Securities, stating the number of the additional New Securities it proposes to buy (the “Additional Number”). If, as a result
thereof, such oversubscription exceeds the total number of the remaining New Securities available for purchase, each 

  
 17 













 
oversubscribing Right Participant will be cut back by the Company with respect to its oversubscription to that number of remaining New Securities equal to the lesser of (x) the Additional
Number and (y) the product obtained by multiplying (i) the number of the remaining New Securities available for subscription by (ii) a fraction, the numerator of which is the number of Ordinary Shares (calculated on a fully-diluted
and as-converted basis) held by such oversubscribing Right Participant and the denominator of which is the total number of Ordinary Shares (calculated on a fully-diluted and
as-converted basis) held by all the oversubscribing Right Participants immediately prior to the issuance of the New Securities giving rise to the Right of Participation. 

(c) Each Right Participant who exercises its Right of Participation hereunder by delivering aforesaid notice shall be obligated to buy such
number of New Securities in accordance with the terms of Section 3.4 and the Company shall so notify the Right Participants within ten (10) Business Days following the date of the Second Participation Notice. The
transaction in connection with the New Securities shall be consummated within forty-five (45) days after the expiration of the Second Participation Period. 

3.5 Failure to Exercise. Upon the expiration of the Second Participation Period, the Company shall have ninety days (90) days
thereafter to sell the New Securities described in the First Participation Notice (with respect to the remaining New Securities) at the same or higher price and upon non-price terms not materially more
favorable to the purchasers thereof than specified in the First Participation Notice, provided that the prospective purchaser of such New Securities shall comply with this Agreement and the Restated Articles, as maybe amended from time to time. In
the event that the Company has not issued and sold such New Securities within such ninety days (90) day period, then the Company shall not thereafter issue or sell any New Securities without again first offering such New Securities to the
Participation Rights Holders pursuant to this Section 3. 
 3.6 Termination. The provisions set forth under
this Section 3 shall terminate upon the earliest to occur of (i) the consummation of the Qualified Initial Public Offering, (ii) the consummation of an IPO in a Recognized Exchange duly approved by the Board where
all Preferred Shares are converted into Ordinary Shares, or where such provisions are required to be terminated by applicable laws or stock exchange requirements; or (iii) the closing of a Deemed Liquidation Event. 

4. TRANSFER RESTRICTIONS. 
 4.1 Certain
Definitions. For purposes of this Section 4, “Ordinary Shares” means (i) the Company’s outstanding Ordinary Shares (other than those issued upon conversion of any Preferred Shares), (ii) the
Company’s outstanding Non-voting Ordinary Shares, and (iii) the Ordinary Shares and the Non-voting Ordinary Shares issuable upon exercise of outstanding
options or warrants; “Preferred Shareholder” means the holder of Series A Preferred Shares and/or holder of Series B Preferred Shares of the Company; “Ordinary Shareholder” means a holder of any Ordinary Share of
the Company; and “Shareholder” means a Preferred Shareholder or an Ordinary Shareholder. 
 4.2 Right of First
Refusal. Subject to Section 4.4 and Section 4.5 of this Agreement, if any Ordinary Shareholder proposes to directly or indirectly (including through a holding entity, special purpose vehicle,
or by any similar methods) sell, assign, pledge, hypothecate, transfer, exchange or otherwise encumber or dispose of in any way or otherwise grant any interest or right (“Transfer”) with respect to all or any part of any interest in
any Ordinary 

  
 18 













 
Shares held by it to any third party (each, a “Selling Shareholder”), then such Selling Shareholder shall promptly give written notice (the “Transfer Notice”) to
the Company and each Preferred Shareholder (the “Non-Selling Shareholders”) prior to such Transfer. The Transfer Notice shall describe in reasonable detail the proposed Transfer including,
without limitation, the number of Ordinary Shares to be Transferred (the “Offered Shares”), the nature of such Transfer, the consideration to be paid, and the name and address of each prospective purchaser or transferee. The Company
and the Non-Selling Shareholders may exercise their right of first refusal with respect to the Offered Shares as follows: 

(a) Option of the Company. 

(i) The Company shall have a first option for a period of fifteen (15) Business Days from receipt of the Transfer Notice (the
“Company’s First Refusal Period”) to elect to purchase the Offered Shares at the same price and subject to the same terms and conditions as described in the Transfer Notice (the “Company’s Right of First
Refusal”). The Company may exercise the Company’s Right of First Refusal and purchase all or any portion of the Offered Shares by notifying the Selling Shareholder in writing (the “Company’s First Refusal Notice”)
before expiration of Company’s First Refusal Period as to the number of shares that it wishes to purchase. 
 (ii) In the event that
the Company has declined to exercise its rights to purchase all, or a portion of, the Offered Shares or fails to deliver the Company’s First Refusal Notice within the Company’s First Refusal Period, then the Selling Shareholder shall,
within three (3) days after the expiration of the Company’s First Refusal Period, give each Non-Selling Shareholders a “Secondary Transfer Notice” which shall identify the Offered
Shares with respect to which the Company has declined to purchase or failed to exercise its right of first refusal (the “Remaining Shares”). 

(b) Option of the Preferred Shareholders. 

(i) Each Non-Selling Shareholder shall have an option for a period of twenty (20) Business Days
from receipt of the Secondary Transfer Notice (the “Preferred Shareholders’ First Refusal Period”) to elect to purchase the Remaining Shares at the same price and subject to the same terms and conditions as
described in the Transfer Notice (the “Preferred Shareholders’ Right of First Refusal”). Each Non-Selling Shareholder may exercise the Preferred Shareholders’ Right of
First Refusal and purchase all or any portion of the Remaining Shares by notifying the Selling Shareholder, the Company and each other Non-Selling Shareholder in writing (the “Preferred
Shareholders’ First Refusal Notice”) before expiration of Preferred Shareholders’ First Refusal Period as to the number of shares that it wishes to purchase. The Preferred Shareholders’ First Refusal Notice
shall set forth the number of Remaining Shares that such Non-Selling Shareholder wishes to purchase, which amount shall not exceed the First Refusal Allotment (as defined below) of such Non-Selling Shareholder. 
 (ii) In the event any Non-Selling
Shareholder elects not to purchase its First Refusal Allotment of the Remaining Shares available under Section 4.2(a)(i) within the Preferred Shareholders’ First Refusal Period, then the Selling Shareholder shall
promptly give written notice (the “Preferred Shareholders’ Overallotment Notice”) to each Non-Selling Shareholder that has elected to purchase all of its First Refusal Allotment of the
Remaining Shares (each a “Fully Participating Preferred Shareholder”), which notice shall set forth the number of Remaining Shares not purchased by the other Non-Selling Shareholders


  
 19 













 
(“Preferred Shareholders’ Overallotment Shares”), and shall offer the Fully Participating Preferred Shareholders the right to acquire its First Refusal Allotment of the
Preferred Shareholders’ Overallotment Shares. Each Fully Participating Preferred Shareholder shall have five (5) Business Days after receipt of the Preferred Shareholders’ Overallotment Notice (the “Preferred
Shareholders’ Overallotment Period”) to deliver a written notice to the Selling Shareholder (the “Participating Preferred Shareholders’ Overallotment Notice”) of its election to purchase its First Refusal
Allotment of the Preferred Shareholders’ Overallotment Shares on the same terms and conditions as set forth in the Transfer Notice, which such Participating Preferred Shareholders’ Overallotment Notice shall also indicate the maximum
number of the Preferred Shareholders’ Overallotment Shares that such Fully Participating Preferred Shareholder will purchase in the event that any other Fully Participating Preferred Shareholder elects not to purchase its First Refusal
Allotment of the Preferred Shareholders’ Overallotment Shares. 
 (c) First Refusal Allotment. Each Non-Selling Shareholder shall have the right to purchase that number of the Remaining Shares or Preferred Shareholders’ Overallotment Shares, as the case may be (the “First Refusal Allotment”),
equivalent to the product obtained by multiplying the aggregate number of the Remaining Shares or Preferred Shareholders’ Overallotment Shares, as the case may be, by a fraction, the numerator of which is the number of Ordinary Shares (on an as-converted basis) held by such Non-Selling Shareholder at the time of the transaction and the denominator of which is the total number of Ordinary Shares (on an as-converted basis) owned by all Non-Selling Shareholders at the time of the transaction who have the right of first refusal to purchase the applicable shares and have elected
to participate in such right of first refusal purchase. A Non-Selling Shareholder shall not have a right to purchase any of the Remaining Shares or Preferred Shareholders’ Overallotment Shares, as
applicable, unless it exercises its right of first refusal within the Preferred Shareholders First Refusal Period or the Preferred Shareholders’ Overallotment Period, as applicable, to purchase up to all of its First Refusal Allotment of the
Remaining Shares or Preferred Shareholders’ Overallotment Shares, as applicable. 
 (d) Purchase Price and Payment. The purchase
price for the Offered Shares to be purchased by the Company and/or the Non-Selling Shareholders exercising their right of first refusal will be the price set forth in the Transfer Notice, but will be payable
as set forth below. If the purchase price in the Transfer Notice includes consideration other than cash, the cash equivalent value of the non-cash consideration will be as previously determined by the Board in
good faith (including affirmative votes of the Series B Director and a majority of the Series A Directors) or by a third party appraisal institution engaged by the Board, which determination will be binding upon the Company, the Selling Shareholder
and the Non-Selling Shareholders, absent fraud or error. The transaction shall be closed within forty-five (45) Business Days following the date of the Transfer Notice and the payment of the purchase
price shall be made by wire transfer or check as directed by the Selling Shareholder. 
 (e) Expiration Notice. Within five
(5) days after the expiration of the Preferred Shareholders’ Overallotment Period, the Company will give written notice (the “First Refusal Expiration Notice”) to the Selling Shareholder and the Non-Selling Shareholders specifying either (i) that all of the Offered Shares were subscribed by the Company and/or the Non-Selling Shareholders exercising their rights
of first refusal, or (ii) that the Company and/or the Non-Selling Shareholders have not subscribed for all of the Offered Shares in which case the First Refusal Expiration Notice will specify the Co-Sale Pro Rata Portion (as defined below) of the remaining Offered Shares for the purpose of the co-sale right of the holders of the Preferred Shares described in

 (f) Rights of a Selling Shareholder. If the Company and/or any Non-Selling Shareholder exercises its right of first refusal to purchase the Offered Shares, then, upon the date the notice of such exercise is given by the Company and/or such
Non-Selling Shareholder, the Selling Shareholder will have no further rights as a holder of such Offered Shares except the right to receive payment for such Offered Shares from the Company and/or such Non-Selling Shareholder in accordance with the terms of this Agreement, and the Selling Shareholder will forthwith cause all certificate(s) evidencing such Offered Shares to be surrendered to the Company for
cancellation and deliver to the Company a duly executed share transfer in respect of the Offered Shares to be transferred to the Company and/or such Non-Selling Shareholder, and the Company shall update its
register of members accordingly. 
 4.3 Preferred Shareholder’s Co-Sale
Right. In the event that the Company and the Non-Selling Shareholders have not exercised their right of first refusal with respect to all of the Offered Shares, then the remaining Offered Shares not
subscribed for under the right of first refusal pursuant to Section 4.2 above shall be subject to co-sale rights under this Section 4.3 and each Non-Selling Shareholder who has not exercised any of its right of first refusal with respect to the Offered Shares shall have the right, exercisable upon written notice to the Selling Shareholder, the Company and
each other Non-Selling Shareholder (the “Co-Sale Notice”) within twenty (20) Business Days after receipt of First Refusal Expiration Notice (the
“Co-Sale Right Period”), to participate in such sale of the Offered Shares on the same terms and conditions as set forth in the Transfer Notice. The
Co-Sale Notice shall set forth the number of Ordinary Shares (on as-converted basis) that such participating Non-Selling
Shareholder wishes to include in such sale or transfer, which amount shall not exceed the Co-Sale Pro Rata Portion (as defined below) of such Non-Selling Shareholder. To
the extent one or more of the Non-Selling Shareholder exercise such co-sale right in accordance with the terms and conditions set forth below, the number of Ordinary
Shares that such Selling Shareholder may sell in the transaction shall be correspondingly reduced. The co-sale right of each Non-Selling Shareholder shall be subject to
the following terms and conditions: 
 (a) Co-Sale Pro Rata Portion. Each Non-Selling Shareholder may sell all or any part of that number of Ordinary Shares held by it that is equal to the product obtained by multiplying (x) the aggregate number of the Offered Shares subject to the co-sale right hereunder by (y) a fraction, the numerator of which is the number of Ordinary Shares (on an as-converted basis) owned by such
Non-Selling Shareholder at the time of the sale or transfer and the denominator of which is the combined number of Ordinary Shares (on an as-converted basis) at the time
owned by all Non-Selling Shareholders who elect to exercise their co-sale rights (if any Non-Selling Shareholder does not elect
to exercise the co-sale right to the full extent then its Ordinary Shares (on as-converted basis) for calculation in the denominator shall be proportionately reduced)
and the Selling Shareholder (“Co-Sale Pro Rata Portion”). 
 (b) Transferred
Shares. Each participating Non-Selling Shareholder shall effect its participation in the sale by promptly delivering to the Selling Shareholder for transfer to the prospective purchaser one or more
certificates, in addition to a duly executed instrument of transfer which represent: 
 (i) the number of Ordinary Shares which such Non-Selling Shareholder elects to sell; 

  
 21 













 (ii) that number of Preferred Shares which is at such time convertible into the number of
Ordinary Shares that such Non-Selling Shareholder elects to sell; provided in such case that, if the prospective purchaser objects to the delivery of Preferred Shares in lieu of Ordinary Shares, such Non-Selling Shareholder shall convert such Preferred Shares into Ordinary Shares and deliver Ordinary Shares as provided in subsection 4.3(b)(i) above. The Company agrees to make any such conversion
concurrent with the actual transfer of such shares to the purchaser; or 
 (iii) a combination of the above. 

(c) Payment to Preferred Shareholder. The share certificate or certificates that the participating
Non-Selling Shareholder delivers to the Selling Shareholder pursuant to Section 4.3(b) shall be surrendered to the Company for cancellation and the register of members of the Company
shall be updated in consummation of the sale of the Offered Shares pursuant to the terms and conditions specified in the Transfer Notice, and the Selling Shareholder shall concurrently therewith remit to such
Non-Selling Shareholder that portion of the sale proceeds to which such Non-Selling Shareholder is entitled by reason of its participation in such sale. To the extent
that any prospective purchaser or purchasers prohibits such assignment or otherwise refuses to purchase any shares or other securities from a Non-Selling Shareholder exercising its co-sale right hereunder, the Selling Shareholder shall not sell to such prospective purchaser or purchasers any Ordinary Shares unless and until, simultaneously with such sale, the Selling Shareholder shall purchase
such shares or other securities from such Non-Selling Shareholder. 
 (d) Right to Transfer.
To the extent the Non-Selling Shareholders do not elect to participate in the sale of the Offered Shares subject to the Transfer Notice, the Selling Shareholder may, not later than ninety (90) Business
Days following delivery to the Company and each of the Non-Selling Shareholders of the Transfer Notice, conclude a transfer of the remaining Offered Shares covered by the Transfer Notice and not elected to be
purchased by the Company and/or the Non-Selling Shareholders, which in each case shall be on substantially the same terms and conditions as those described in the Transfer Notice. In the event the Selling
Shareholder does not consummate the sale of such Offered Shares within ninety (90) Business Days in accordance with this Section 4.3(d), the rights of the Company and the
Non-Selling Shareholders under Sections 4.2 and 4.3 shall be re-invoked and shall be applicable to each subsequent disposition of such Offered Shares by
the Selling Shareholder until such rights lapse in accordance with the terms of this Agreement. The Selling Shareholders shall cause any prospective purchaser of such shares to comply with this Agreement and Restated Articles, as maybe amended from
time to time. Any proposed transfer on terms and conditions which are materially different from those described in the Transfer Notice, as well as any subsequent proposed transfer of any Ordinary Shares by the Selling Shareholder, shall again be
subject to the right of first refusal of the Company and the Non-Selling Shareholders and the co-sale right of the Non-Selling
Shareholder and shall require compliance by the Selling Shareholder with the procedures described in Sections 4.2 and 4.3 of this Agreement. 

4.4 Permitted Transfers. Notwithstanding anything to the contrary contained herein, the right of first refusal and co-sale rights of the Company and/or the Preferred Shareholder as set forth in Section 4.2 and Section 4.3 above and the transfer restrictions set forth in
Section 4.5 below shall not apply to (a) any sale or Transfer of Ordinary Shares to the Company pursuant to a repurchase right or right of first refusal held by the Company in the event of a termination (either
voluntary or involuntary) of employment or consulting relationship; and (b) any Transfer by an Ordinary Shareholder of Ordinary Shares held by such

their satisfaction and that any such Permitted Transferee agrees in writing to be bound by this Agreement in place of the relevant transferor; provided, further, that such transferor shall remain liable for any breach by such Permitted
Transferee of any provision hereunder.

(b) No Shareholder may directly or indirectly Transfer any Shares to any Competitor. 

(c) Any attempt by a Party to sell or transfer any share of the Company in violation of this Section 4 shall be void
and the Company hereby agrees it will not effect such a transfer nor will it treat any alleged transferee as the holder of such shares without the requisite written consent. 

4.6 Restriction on Indirect Transfers. The Parties agree that the transfer restrictions set out in this
Section 4 shall not be circumvented or otherwise avoided by the holding of any Equity Securities of the Company indirectly through a company or other entity that can itself be sold in order to dispose of an interest in the
Equity Securities of the Company free of such restrictions. Any transaction or Transfer directly or indirectly of shares of a shareholder of the Company or of any company (or other entity) having Control (as defined in
Section 12.6 below) over such shareholder of the Company shall be treated as a transfer of the Equity Securities of the Company held by that Shareholder, and the provisions of this Agreement that apply in respect of the
transfer of Equity Securities of the Company shall apply to such transfer.

9. COVENANTS; UNDERTAKINGS 
 9.1
Controlled Foreign Corporation. Each year, based on and in reliance of the information provided by the shareholders of the Company (the “Shareholders”) within a reasonable time after being requested, the Company shall make
due inquiry with its tax advisors regarding whether the Company or any of its Subsidiaries is treated as a “Controlled Foreign Corporation” (“CFC”) as defined in the United States Internal Revenue Code of 1986 (the
“Code”), whether any portion of the Company’s or any of its Subsidiaries’ income is (a) “Subpart F Income” (as defined in Section 952 of the Code) (“Subpart F Income”) or (b) “global
intangible low-taxed income” (as defined in Section 951A(b) of the Code) (“GILTI”) and each Shareholder’s share, if any, of such Subpart F Income and/or GILTI (regardless of
whether a Shareholder is a “United States Shareholder” or not). Upon written request of any Investor who is a United States Shareholder (or whose direct or indirect owners are United States Shareholders) with respect to the Company or any
Group Company within the meaning of Section 951(b) of the Code, the Company will (i) use best efforts to provide in writing such information as is in its possession and reasonably available concerning its Shareholders and Affiliates to
assist such Investor in determining whether the Company or any Group Company is a CFC and (ii) provide such Investor with reasonable access to such information as is in the Company’s or Group Company’s possession and reasonably
available as may be required by such Investor (A) to determine the Company’s (or Group Company’s) status as a CFC, (B) to determine whether such Investor is required to report its pro rata portion of the Company’s (or


  
 32 













 
Group Company’s) “Subpart F income” (as defined in Section 952 of the Code) on its United States federal income tax return, or (C) to allow such Investor to
otherwise comply with applicable United States federal income tax laws (including with respect to the making of any determinations under Section 951A of the Code); provided that the Company may require such Investor to enter into a
confidentiality agreement in customary form. 
 9.2 Passive Foreign Investment Company.
The Company shall use commercially reasonable efforts to avoid being a “passive foreign investment company” within the meaning of Section 1297 of the Code (“PFIC”) for the current and any future taxable year.
The Company shall make due inquiry with its tax advisors on at least an annual basis regarding its status as a PFIC, and if the Company is informed by its tax advisors that it has become a PFIC, or that it is likely that the Company will be
classified as a PFIC for any taxable year, the Company shall promptly notify each Investor of such status or risk, as the case may be, in each case no later than forty-five (45) days following the end of the Company’s taxable
year. The Company shall provide its Investors with annual financial information in the form to the reasonable satisfaction of such Investor as soon as reasonably practicable following the end of each taxable year of such Investor (but in no

reasonably available, as may be required for purposes of filing U.S. federal income tax returns in connection with a qualified electing fund election or other tax filing in respect of the Company’s status of a PFIC. In the event that it is
determined by the Company’s or such Investor’s tax advisors that the control documents in place between one or more of the Company’s wholly owned Subsidiaries and/or the Company, on the one hand, and any of the Group Companies
organized in the PRC that is not a wholly foreign owned enterprise, on the other hand, do not allow the Company to look through the Group Companies to their assets and income for purposes of the PFIC rules and regulations under the Code, the
Company shall use its best efforts to take such actions as are reasonably necessary or advisable, including the amendment of such control documents, to qualify for such look-through treatment of the Group Companies under the PFIC rules and
regulations under the Code. 
 9.3 U.S. Federal Income Tax. The Company is currently classified as a corporation (and not as a
partnership) for U.S. federal income tax purposes and shall not take any action (including the making of any election) inconsistent with the Company’s or any of its Subsidiaries’ classification for U.S. federal income tax purposes as a
corporation without the prior written consent of the Majority Preferred Shareholders. 
 9.4 Subsidiary Covenants. The Company shall
at any time institute and shall keep in place arrangements satisfactory to the Board such that the Company (i) will control the operations of any Group Company and (ii) will be permitted to properly consolidate the financial results for

officers, employees, agents and other persons acting on its behalf or purporting to act on its behalf to, comply with the US Foreign Corrupt Practices Act, as amended, in all material respects. 

9.5 Additional Covenants. The Company shall take all necessary actions to maintain its Subsidiaries, as is necessary to conduct the
Company’s business as conducted or as proposed to be conducted. The Company shall, and shall use its best efforts to cause each Group Company to, comply in all material respects with all applicable Laws, rules, and regulations on a continuing
basis. All material aspects of such formation, maintenance and compliance of each Group Company shall be subject to the review, approval and oversight by the Board.

Ascendis nor its Controlled Affiliates shall be deemed to have engaged in any Competing Business as a result of any activities performed under such agreements: (a) [***] and (b) [***]. In the event that any entity, in which Ascendis owns directly or
indirectly [***] percent ([***]%) or more of the issued share capital and/or Ascendis is not merely a passive investor, becomes [***] in the Competing Business, Ascendis shall decrease its holding in such entity to less than [***] percent ([***]%)
immediately and in any event within [***] ([***]) months after the time when Ascendis comes to own directly or indirectly [***] percent ([***]%) or more of the issued share capital of such entity engaged in the Competing Business [***]. The

its pro rata ownership of the Company (on an as-converted basis), and if any Investor elects not to exercise its right of first 

  
 34 













 
refusal with respect to such shares, it shall have the right to sell its pro rata shares together with the transferring grantee pursuant to Section 4.3 above. In
