 5 








 (c) Notwithstanding the foregoing, the Company shall not be obligated to
take any action to effect or complete any such registration pursuant to this Section 2.1: 
 (i) In any
particular jurisdiction in which the Company would be required to execute a general consent to service of process in effecting such registration, qualification or compliance unless the Company is already subject to service in such jurisdiction and
except as may be required by the Securities Act; 
 (ii) Following the filing of, and for one hundred eighty
(180) days immediately following the effective date of, any registration statement pertaining to securities of the Company (other than a registration of securities in a Rule 145 transaction or with respect to an employee benefit plan);

 (iii) After the Company has effected two (2) such demand registrations pursuant to this
Section 2.1; or 
 (iv) If the Initiating Holders propose to dispose of shares of Registrable Securities
that may be immediately registered on Form F-3 pursuant to a request made pursuant to Section 2.3 below. 

(d) Underwriting. In the event that the Initiating Holders intend to distribute the Registrable Securities by
means of an underwriting, the Company shall advise the Holders as part of the notice given pursuant to Section 2.1(a) hereof that the right of any Holder to registration pursuant to this Section 2.1 shall be conditioned upon such
Holder’s participation in the underwriting arrangements required by this Section 2.1, and the inclusion of such Holder’s Registrable Securities in the underwriting, to the extent requested, shall be limited to the extent provided
herein. 
 All Holders proposing to distribute their securities through such underwriting shall (together with
the Company and the other Holders distributing their securities through such underwriting) enter into an underwriting agreement in customary form with the managing underwriter selected for such underwriting by such Holders. Notwithstanding any other
provision of this Section 2.1, if the managing underwriter determines that marketing factors require a limitation of the number of shares to be underwritten, the managing underwriter may limit the Registrable Securities to be included in such
registration (i) in the case of the Company’s Initial Public Offering, to zero, and (ii) in the case of any other offering, to an amount no less than thirty percent (30%) of the Registrable Securities requested to be registered.
The Registrable Securities held by the Company’s directors, officers, employees, consultants and Ordinary Holders shall be reduced completely before any reduction is made to the Registrable Securities held by the Preferred Holders. The Company
shall so advise all Holders requesting to be included in the registration and underwriting, and the number of shares of Registrable Securities that the managing underwriter determines may be included in the registration and underwriting shall be
allocated among all the Holders requesting to be included in the registration and underwriting in proportion, as nearly as practicable, to the respective amounts of Registrable Securities held by them at the time of filing the registration
statement. 

  
 6 








 To facilitate the allocation of shares in accordance with the above
provisions, the Company or the underwriters may round the number of shares allocated to any Holder to the nearest one hundred (100) shares. If any Holder disapproves of the terms of the underwriting, such Holder may elect to withdraw therefrom
by written notice to the Company, the managing underwriter and the Initiating Holders. The Registrable Securities and/or other securities so withdrawn shall also be withdrawn from registration. 

2.2 Company Registration. 

(a) Notice of Registration. If at any time, or from time to time, the Company determines to register any of its
Registrable Securities, either for its own account or the account of a Holder, other than (i) a registration relating solely to employee benefit plans, (ii) a registration relating solely to a Rule 145 transaction, or (iii) a
registration in which the only Registrable Securities being registered are Ordinary Shares issuable upon conversion of convertible debt securities which are also being registered, the Company will: 

(i) promptly give to each Holder written notice thereof; and 

(ii) include in such registration (and any related qualifications including compliance with Blue Sky laws), and in any
underwriting involved therein, all the Registrable Securities specified in a written request or requests, made within ten (10) days after the date of such written notice from the Company, by any Holder. 

(b) Underwriting. If the registration of which the Company gives notice is for a registered public offering
involving an underwriting, the Company shall so advise the Holders as a part of the written notice given pursuant to Section 2.2(a)(i) hereof. In such event, the right of any Holder to registration pursuant to Section 2.2 hereof shall be
conditioned upon such Holder’s participation in such underwriting and the inclusion of Registrable Securities in the underwriting shall be limited to the extent provided herein. 

All Holders proposing to distribute their securities through such underwriting shall (together with the Company and the
other Holders distributing their securities through such underwriting) enter into an underwriting agreement in customary form with the managing underwriter selected for such underwriting by the Company. Notwithstanding any other provision of this
Section 2.2, if the managing underwriter determines that marketing factors require a limitation of the number of shares to be underwritten, the managing underwriter may limit the Registrable Securities to be included in such registration
(i) in the case of the Company’s Initial Public Offering, to zero, and (ii) in the case of any other offering, to an amount no less than thirty percent (30%) of the Registrable Securities requested to be registered. The
Registrable Securities held by the Company’s directors, officers, employees, consultants and Ordinary Holders shall be reduced completely before any reduction is made to the Registrable Securities held by the Preferred Holders. The Company
shall so advise all Holders requesting to be included in the registration and underwriting, and the number of shares of Registrable Securities that the managing underwriter determines may be included in the registration and underwriting shall be
allocated among all the Holders requesting to be included in the registration and underwriting in proportion, as nearly as practicable, to the respective amounts of Registrable Securities held by them at the time of filing the registration
statement. 

  
 7 








 To facilitate the allocation of shares in accordance with the above
provisions, the Company or the underwriters may round the number of shares allocated to any Holder to the nearest one hundred (100) shares. If any Holder disapproves of the terms of the underwriting, such Holder may elect to withdraw therefrom
by written notice to the Company and the managing underwriter and the Initiating Holders. The Registrable Securities and/or other securities so withdrawn shall also be withdrawn from registration. 

(c) Right to Terminate Registration. The Company shall have the right to terminate or withdraw any registration
initiated by it under this Section 2.2 prior to the effectiveness of such registration whether or not any Holder has elected to include securities in such registration. 

2.3 Registration on Form F-3. 

(a) Request for Registration. In case the Company receives from Holders a written request that the Company file a
registration statement on Form F-3 (or any successor form to Form F-3) for a public offering of shares of the Registrable Securities, and the Company is a registrant entitled to use Form F-3 to register the Registrable Securities for such an
offering, the Company shall: 
 (i) promptly give written notice to all other Holders of the proposed
registration and offer them the opportunity to participate; and 
 (ii) use its reasonable best efforts to
cause such Registrable Securities to be registered for the offering on such form as such Holder or Holders may reasonably request; in each case within thirty (30) days of the mailing of such notice by the Company in accordance with
Section 5.7 hereof. 
 If such offer is to be an underwritten offer, the underwriters must be acceptable to
both the Holders and the Company. In the event the registration is proposed to be part of a firm commitment underwritten public offering, the substantive provisions of Section 2.1(d) hereof shall be applicable to each such registration
initiated under this Section 2.3. 
 (b) Notwithstanding the foregoing, the Company shall not be obligated
to take any action pursuant to this Section 2.3: 
 (i) Following the filing of, and for one hundred
eighty (180) days immediately following the effective date of, any registration statement pertaining to securities of the Company (other than (i) a registration of securities in a Rule 145 transaction, (ii) a registration with respect
to an employee benefit plan, or (iii) a registration with respect to capital stock underlying the issuance of convertible debt), provided that (A) the Company is actively employing in good faith its reasonable best efforts to cause such
registration statement to become effective, and (B) the Registrable Securities of Holders have not been excluded (with respect to all or any portion of the Registrable Securities the Holders requested to be included in such registration)
pursuant to the provisions of Sections 2.1(d) or 2.2(b); 

  
 8 








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

(iii) If the Company, within ten (10) days of the receipt of the request of the Initiating Holders, pursuant to
this Section 2.3, gives notice of its bona fide intention to effect the filing of a registration statement with the SEC within sixty (60) days of receipt of such request (other than with respect to a registration statement relating to
(i) a Rule 145 transaction, (ii) for an employee benefit plan or (iii) an offering solely to employees or a registration with respect to capital stock underlying the issuance of convertible debt), provided, that the Company is
actively employing in good faith its reasonable best efforts to cause that registration statement to become effective within sixty (60) days of receipt of that request; provided, further, that the Holders are entitled to join such
registration. 
 2.4 Expenses of Registration. All Registration Expenses incurred in connection with
(i) two (2) registrations pursuant to Section 2.1 hereof, (ii) all registrations pursuant to Section 2.2 hereof, and (iii) all registrations pursuant to Section 2.3 hereof shall be borne by the Company.
Notwithstanding the foregoing, in the event that Holders cause the Company to begin a registration pursuant to Sections 2.1 or 2.3 hereof, and the request for such registration is subsequently withdrawn by the Holders (unless the withdrawal is based
upon material adverse information concerning the Company of which the Holders were not aware at the time of such request, in which case the Company will bear all Registration Expenses relating to such withdrawn offering), all Holders shall be deemed
to have forfeited their right to one registration under Sections 2.1 or 2.3 hereof, as the case may be, unless the Initiating Holders with respect to a registration pursuant to Section 2.1 and Holders with respect to a registration pursuant to
Section 2.3 pay for, or reimburse the Company for, the Registration Expenses incurred in connection with such withdrawn or incomplete registration. Unless otherwise stated herein, all Selling Expenses relating to securities registered on behalf
of the Holders and all other Registration Expenses shall be borne by the Holders of such securities pro rata on the basis of the number of shares so registered or proposed to be so registered. 

2.5 Registration Procedures. In the case of each registration effected by the Company pursuant to this Agreement,
the Company will keep each Holder advised in writing as to the initiation of such registration and as to the completion thereof. The Company will: 
 (a) Prepare and file with the SEC a registration statement with respect to such securities and use its reasonable best efforts to cause such registration statement to become and remain effective for at
least one hundred eighty (180) days or until the distribution described in the Registration Statement has been completed; provided, however, that (i) such one hundred eighty (180) day period shall be extended for a period of time
equal to the period the Holder refrains from selling any securities included in such registration at the request of an underwriter of Ordinary Shares (or other securities) of the Company; 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, subject to compliance with applicable SEC rules, such one hundred eighty (180) day period shall be extended, if necessary, to keep the registration
statement effective until all such Registrable Securities are sold. Notwithstanding the foregoing, the Company shall be entitled to suspend effectiveness of the registration statement for up to ninety (90) days if the Company shall furnish to
the Holder a certificate signed by the Chief Executive Officer of the Company stating that in the good faith judgment of the Board of Directors of the Company (the “Board”), it would not be in the best interests of the Company and
its shareholders for such registration statement to continue to be effective because the Company is engaged in any activity or transaction or preparations or negotiations for any activity or transaction (“Company Activity”) that the
Company has a bona fide business purpose for preserving as confidential, and the Company determines in good faith that the public disclosure requirement imposed on the Company pursuant to such registration statement would require premature
disclosure of the Company Activity; provided, however, that the Company may not invoke this right more than once in any twelve (12) month period. 

  
 9

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;

such securities; 
 (d) Furnish, at the request of any Holder requesting registration of Registrable Securities,
(i) an opinion, dated the date of such request, 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) a letter dated the date of such date, from the independent accountants of the Company, in form and substance as is customarily given by
independent accountants to underwriters in an underwritten public offering, addressed to the underwriters, if any, and to the Holders requesting registration of Registrable Securities; 

(e) Use its reasonable best efforts to register and qualify the securities covered by such registration statement under
such other securities or Blue Sky laws of such jurisdiction as shall be reasonably requested by the Holders, provided that the Company shall not be required in connection therein 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; 
 (f) In the event of any

(g) Notify each Holder 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;


  
 10 









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

(i) Provide a transfer agent and registrar for all Registrable Securities registered pursuant hereunder and a CUSIP

 2.6 Indemnification. 
 (a) The Company will indemnify each
Holder, each of its officers, directors, partners, counsel, underwriters, and each person controlling such Holder within the meaning of the Securities Act or the Exchange Act, with respect to which registration has been effected pursuant to this
Agreement, against all expenses, claims, losses, damages or liabilities (or actions in respect thereof), including any of the foregoing incurred in settlement of any litigation, commenced or threatened, arising out of or based on any untrue
statement (or alleged untrue statement) of a material fact contained in any registration statement, prospectus, offering circular or other document, or any amendment or supplement thereto, incident to any such registration, or based on any omission
(or alleged omission) to state therein a material fact required to be stated therein or necessary to make the statements therein, in light of the circumstances in which they were made, not misleading, or any violation by the Company of the
Securities Act, the Exchange Act, state securities laws or any rule or regulation promulgated under such laws applicable to the Company in connection with any such registration, and the Company will reimburse each such Holder, each of its officers,
directors, partners, counsel, underwriters, and each person controlling such Holder, for any legal and any other expenses reasonably incurred, as such expenses are incurred, in connection with investigating, preparing or defending any such claim,
loss, damage, liability or action, provided that the Company will not be liable in any such case (i) to the extent that any such claim, loss, damage, liability or expense arises out of or is based on any untrue statement or omission or alleged
untrue statement or omission, made in reliance upon and in conformity with written information furnished to the Company by an instrument duly executed by such Holder or any officer, director, partner, counsel, underwriter thereof or such controlling
person, and stated to be specifically for use therein or (ii) if the delivery of the final disclosure document, or any supplement or amendment thereto, to any party by the Holder would have cured such untrue statement, alleged untrue statement,
omission or alleged omission, and the Holder failed to deliver such circular, amendment or supplement. 
 (b)
Each Holder will, if Registrable Securities held by such Holder are included in the securities as to which such registration is being effected, severally and not jointly indemnify the Company, each of its directors and officers, other holders of the
Company’s securities covered by such registration statement, each of such other holder’s directors, officers, partners, each person controlling such holder within the meaning of the Securities Act, each person who controls the Company
within the meaning of the Securities Act, and each other such Holder, each of its officers and directors and partners and each person controlling such Holder within the meaning of the Securities Act, against all claims, losses, damages and
liabilities (or actions in respect thereof) arising out of or based on any untrue statement (or alleged untrue statement) of a material fact contained in any such registration statement, prospectus, offering circular or other document, or any
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 any violation by the Holder of the Securities Act, the Exchange Act, state securities laws
or any rule or regulation promulgated under such laws applicable to the Holder, and will reimburse the Company, such other Holders and holders, such directors, officers, partners, underwriters or controlling persons for any legal or any other
expenses reasonably incurred, as such expenses are incurred, in connection with investigating or defending any such claim, loss, damage, liability or action, but in the case of the Company, the other Holders and holders and their respective
officers, directors, partners or controlling persons, only to the extent that such untrue statement (or alleged untrue statement) or omission (or alleged omission) is made in such registration statement, prospectus, offering circular or other
document in reliance upon and in conformity with written information furnished to the Company by an instrument duly executed by such Holder, and stated to be specifically for use in such registration statement, prospectus, offering circular or other
document. Notwithstanding the foregoing, the liability of each Holder under this subsection 2.6(b) shall be limited to an amount equal to the net proceeds resulting from the shares sold by such Holder, unless such liability arises out of or is based
on the willful misconduct of such Holder. 

  
 11 









 (c) Each party entitled to indemnification under this Section 2.6 (the
“Indemnified Party”) shall give notice to the party required to provide indemnification (the “Indemnifying Party”) promptly after such Indemnified Party has actual knowledge of any claim as to which indemnity may be
sought, and shall permit the Indemnifying Party to assume the defense of any such claim or any litigation resulting therefrom, provided that counsel for the Indemnifying Party, who shall conduct the defense of such claim or litigation, shall be
approved by the Indemnified Party (whose approval shall not unreasonably be withheld), and the Indemnified Party may participate in such defense at such party’s expense, and provided further that the failure of any Indemnified Party to give
notice as provided herein shall not relieve the Indemnifying Party of its obligations under this Agreement unless the failure to give such notice is materially prejudicial to an Indemnifying Party’s ability to defend such action and provided
further, that the Indemnifying Party shall not assume the defense for matters as to which there is a conflict of interest or there are separate and different defenses. No Indemnifying Party, in the defense of any such claim or litigation, shall,
except with the consent of each Indemnified Party (whose consent shall not be unreasonably withheld), 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. 

(d) If the indemnification provided for in this Section 2.6 is held by a court of competent jurisdiction to be
unavailable to an indemnified party with respect to any loss, liability, claim, damage, or expense referred to therein, then the indemnifying party, in lieu of indemnifying such indemnified party hereunder, shall contribute to the amount paid or
payable by such indemnified party as a result of such loss, liability, claim, damage, or expense in such proportion as is appropriate to reflect the relative fault of the indemnifying party on the one hand and of the indemnified party on the other
in connection with the statements or omissions that resulted in such loss, liability, claim, damage, or expense as well as any other relevant equitable considerations. The relative fault of the indemnifying party and of the indemnified party shall
be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission to state a material fact relates to information supplied by the indemnifying party or by the indemnified party and
the parties’ relative intent, knowledge, access to information, and opportunity to correct or prevent such statement or omission. 

  
 12 









 (e) Notwithstanding the foregoing, to the extent that the provisions on
indemnification and contribution contained in the underwriting agreement entered into in connection with the underwritten public offering are in actual, direct conflict with the foregoing provisions, the provisions in the underwriting agreement
shall control. For the purposes of this Section 2.6(e), the failure of an underwriting agreement to provide indemnification to the Holder as provided in this Agreement shall not be deemed to be in conflict with the provisions of this Agreement
and the indemnification provisions of this Section 2.6 shall remain in force. 
 (f) The obligations of the
Company and Holders under this Section 2.6 shall survive the completion of any offering of Registrable Securities in a registration statement under this Section 2.6, and otherwise. 

2.7 Information by Holder. The Holder or Holders of Registrable Securities included in any registration shall
furnish to the Company such information regarding such Holder or Holders, the Registrable Securities held by them and the distribution proposed by such Holder or Holders as the Company may request in writing and as shall be required in connection
with any registration referred to in this Agreement. 
 2.8 Rule 144 Reporting. With a view to making
available 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, after completion of an initial registered public offering, the Company agrees
to use reasonable best efforts 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 that the Company becomes subject to the reporting requirements of the Securities Act or the Exchange Act; 

(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, furnish to the Holder forthwith upon request a written statement by the Company as to its compliance with the reporting requirements of said Rule 144 (at any time after ninety (90) days after
the effective date of the first registration statement filed by the Company for an offering of its securities to the general public), a copy of the most recent annual or quarterly report of the Company, and such other reports and documents of the
Company and other information in the possession of or reasonably obtainable by the Company as the Holder may reasonably request in availing itself of any rule or regulation of the SEC allowing the Holder to sell any such securities without
registration. 

  
 13 









 2.9 Assignment of Registration Rights. The rights to cause the
Company to register Registrable Securities pursuant to this Section 2 may be assigned (but only with all related obligations under this Agreement) by a Holder to a transferee or assignee of such securities that after such assignment or
transfer, holds at least 100,000 shares of Registrable Securities (subject to appropriate adjustment for share splits, share dividends, combinations or the like), provided: (a) the Company is, within a reasonable time after such transfer,
furnished with written notice of the name and address of such transferee or assignee and the securities with respect to which such registration rights are being assigned; and (b) such transferee or assignee agrees in writing to be bound by and
subject to the terms and conditions of this Agreement, including, without limitation, the provisions of Section 2.11 below. 
 2.10 Limitations on Subsequent Registration Rights. From and after the date of this Agreement, the Company shall not, without the prior written consent of the Preferred Holders holding at least a
majority of the then outstanding Registrable Securities, 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 the Registrable Securities. 

2.11 “Market Stand off” Agreement. 

(a) Each Shareholder hereby agrees that it will not, without the prior written consent of the managing underwriter,
during the period commencing on the date of the final prospectus relating to the Company’s Initial Public Offering or an subsequent firm commitment underwritten public offering (the “Lockup Start Date”) and ending on the date
specified by the Company and the managing underwriter (such period not to exceed one hundred eighty (l80) days in the case of the Initial Public Offering and not to exceed ninety (90) days in the case of any such subsequent offering)
(i) lend, offer, pledge, sell, contract to sell, sell any option or contract to purchase, purchase any option or contract to sell, grant any option, right or warrant to purchase, or otherwise transfer or dispose of, directly or indirectly, any
shares of Ordinary Shares or any securities convertible into or exercisable or exchangeable for Ordinary Shares held immediately prior to the Lockup Start Date, or (ii) enter into any swap or other arrangement that transfers to another, in
whole or in part, any of the economic consequences of ownership of the Ordinary Shares, whether any such transaction described in clause (i) or (ii) above is to be settled by delivery of Ordinary Shares or other securities, in cash or
otherwise (such period, the “Market Standoff Period”). The foregoing provisions of this Section 2.11 shall only be applicable to the Holders if all officers, directors and greater than one percent (1%) shareholders of the
Company enter into similar agreements, to the extent requested by the managing underwriter. If the Company or any underwriter releases any officer, director or holder of one percent (1%) or more of the Company’s outstanding share capital
from his or her 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 underwriters in connection with the Company’s Initial
Public Offering are intended third party beneficiaries of this Section 2.11 and shall have the right, power and authority to enforce the provisions hereof as though they were a party hereto. Each Holder further agrees to execute such agreements
as may be reasonably requested by the underwriters in the Company’s Initial Public Offering that are consistent with this Section 2.11 or that are necessary to give further effect thereto. Any discretionary waiver or termination of the
restrictions of any or all of such agreements by the Company or the underwriters shall apply to all Holders and other persons subject to such agreements pro rata based on the number of shares subject to such agreements. 

  
 14 









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

(b) Each Shareholder agrees that a legend reading substantially as follows shall be placed on all certificates
representing all Registrable Securities of each Holder (and the shares or securities of every other person subject to the restriction contained in this Section 2.11): 

THE SECURITIES REPRESENTED BY THIS CERTIFICATE ARE SUBJECT TO A LOCK-UP PERIOD OF UP TO 180 DAYS AFTER THE EFFECTIVE DATE
OF AN UNDERWRITTEN REGISTERED PUBLIC OFFERING BY THE ISSUER AS SET FORTH IN AN AGREEMENT BETWEEN THE COMPANY AND THE ORIGINAL PURCHASERS OF THESE SECURITIES, A COPY OF WHICH MAY BE OBTAINED AT THE ISSUER’S PRINCIPAL OFFICE. SUCH LOCK-UP PERIOD
IS BINDING ON TRANSFEREES OF THESE SHARES. 
 2.12 Termination of Registration Rights. The rights granted
pursuant to Sections 2.1, 2.2 and 2.3 of this Agreement shall terminate with respect to a particular Holder, whenever such Holder is eligible to sell all its shares of Registrable Securities under Rule 144 during any three (3) month period.

 3. Covenants of the Company and Certain Shareholders. 

3.1 Delivery of Financial Statements and Other Information. The Company shall deliver to each Preferred Holder:

 (a) as soon as practicable, but in any event within ninety (90) days after the end of each fiscal year
of the Company, (i) a consolidated income statement for such fiscal year, a consolidated balance sheet of the Company and statement of shareholders’ equity as of the end of such year, and a consolidated statement of cash flows for such
year, such annual financial reports to be in reasonable detail, prepared in accordance with US GAAP or IAS with US GAAP adjustments (in each case consistently applied throughout the period), and audited and certified by a “Big
Four” accounting firm and (ii) a management report that includes a comparison of financial results with the corresponding annual budget; 
 (b) as soon as practicable, but in any event within forty five (45) days after the end of each of the first three (3) quarters of each fiscal year of the Company, (i) an unaudited
consolidated income statement and consolidated statement of cash flows for such fiscal quarter prepared in accordance with US GAAP or IAS with US GAAP adjustments (in each case consistently applied throughout the period except for year-end
adjustments and except for the absence of notes) and an unaudited consolidated balance sheet as of the end of such fiscal quarter and (ii) a management report that includes a comparison of financial results with the corresponding quarterly
budget; 
 (c) as soon as practicable, but in any event at least thirty (30) days prior to the beginning of
each fiscal year, a budget for the upcoming fiscal year; 
 (d) copies of any reports filed by the Company with
any relevant securities exchange, regulatory authority or governmental authority; 
 (e) such other financial
and operating information that the Preferred Holders may reasonably request from time to time; and 

  
 15 









 (f) with respect to all information provided pursuant to subsections
(a) and (b) of this Section 3.1, an instrument executed by the Chief Executive Officer or the Chief Financial Officer of the Company certifying that all information provided therein is true, correct and not misleading and, with
respect to any financial statements, that such financial statements fairly present the financial condition of the Company as of the date specified and its results of operation for the period specified and do not included a misstatement of a material
fact or omit a material fact necessary to make the statements therein, under the circumstances in which they were made, not misleading. 
 The Company shall permit each Preferred Holder, at such Preferred Holder’s expense, to visit and inspect any Group Company’s properties, to examine its books of account and records and to
discuss any Group Company’s affairs, finances and accounts with its officers, directors, accountants, legal counsel and investment bankers, all as may be reasonably requested by the Preferred Holder and permitted under relevant PRC laws,
governmental regulations and policies; provided that the Preferred Holder has given the Company prior written notice of the proposed inspection and any such inspection is accompanied by a Company representative; and provided, further, that
each Preferred Holder shall utilize appropriate internal controls to ensure that any representative of such Preferred Holder that obtains proprietary information of the Company pursuant to this paragraph shall not disclose or discuss such
information with such Preferred Holder’s employees engaged in business operations unrelated to the investment by such Preferred Holder in the Company. 
 3.2 Preemptive Rights. Subject to the terms and conditions specified in this Section 3.2, the Company hereby grants to each Preferred Holder, a right of first refusal with respect to future
issuances by the Company of its Equity Securities. Each time the Company proposes to offer Equity Securities, the Company shall first make an offering of such Equity Securities to each Preferred Holder in accordance with the following provisions:

 (a) The Company shall deliver a notice in accordance with Section 5.7 (“Notice”) to
each of the Preferred Holders stating (i) its bona fide intention to offer such Equity Securities, (ii) the number of such Equity Securities to be offered, (iii) the price and terms upon which it proposes to offer such Equity
Securities and (iv) the proposed purchaser(s) of such Equity Securities. The Notice shall certify that the Company in good faith believes a binding agreement for the issuance is obtainable on the terms set forth in the Notice, and shall include
a copy of any written proposal, term sheet or letter of intent or other agreement relating to the proposed issuance. 
 (b) By written notification received by the Company within fifteen (15) calendar days after the giving of Notice, each Preferred Holder may elect to purchase, at the price and on the terms specified
in the Notice, up to that portion of such Equity Securities that equals the proportion that the number of Ordinary Shares (including Ordinary Shares issuable upon conversion of the Series A Preferred) held by such Preferred Holder as of the date
immediately prior to the issuance of such Equity Securities (such date being the “Measuring Date”) bears to the total number of shares of Ordinary Shares outstanding as of the Measuring Date including for this purpose any Ordinary
Shares issuable pursuant to then exercisable or convertible securities. The Company shall promptly, in writing, inform each Preferred Holder that elects to purchase all the Equity Securities available to it (a “Fully-Exercising
Investor”) of any other Preferred Holder’s failure to do likewise. During the ten (10) day period commencing after such information is given (the “Oversubscription Period”), each Fully-Exercising Investor may
elect to purchase that portion of the Equity Securities for which Preferred Holders were entitled to subscribe, but which were not subscribed for by the Preferred Holders, that is equal to the proportion that the number of Ordinary Shares (including
Ordinary Shares issuable upon conversion of Series A Preferred) held by such Fully Exercising Investor as of the Measuring Date bears to the total number of shares of Ordinary Shares of the Company outstanding as of the Measuring Date including for
this purpose any Ordinary Shares issuable pursuant to then exercisable or convertible securities. 

  
 16 









 (c) The Company may, during the ninety (90) day period following the
expiration of the Oversubscription Period, offer the remaining Equity Securities which Preferred Holders have not purchased pursuant to such rights to the proposed purchaser(s) specified in the Notice at a price not less than that, and upon terms no
more favorable to the offeree than those, specified in the Notice. If the Company has not issued and sold such Equity Securities within such ninety (90) day period, the right provided hereunder shall be deemed to be revived and such Equity
Securities shall not be offered unless first reoffered to the Preferred Holders in accordance herewith. 
 (d)
The right of first refusal in this Section 3.2 shall not be applicable to (i) the issuance or sale of up to 24,000,000 Ordinary Shares (or options therefor) (as adjusted for any share splits, share dividends and the like) to employees,
officers, directors, consultants and other service providers for the primary purpose of soliciting or retaining their services pursuant to plans or agreements approved by the Board and in accordance with Section 10(A)(6)(d) of the Amended
Memorandum; (ii) the issuance of securities pursuant to a bona fide public offering of Ordinary Shares, (iii) the issuance of securities pursuant to the conversion or exercise of convertible or exercisable securities, options, warrants or
other rights, (iv) the issuance of securities in connection with a bona fide business acquisition of or by the Company, whether by merger, consolidation, sale of assets, sale or exchange of securities or otherwise, approved in accordance with
Section 10(A)(6)(d) of the Company’s Amended and Restated Memorandum of Association (the “Amended Memorandum”), (v) Ordinary Shares issued pursuant to a share split, share dividend or similar reorganization and
(vi) securities issued or issuable to financial institutions or lessors in connection with commercial credit arrangements or similar transactions. In addition to the foregoing, the right of first refusal in this Section 3.2 shall not be
applicable with respect to any Preferred Holder in any offering of Equity Securities if (i) at the time of such offering, the Preferred Holder is not an “accredited investor,” as that term is then defined in Rule 501(a) of Regulation
D under the Securities Act, and (ii) such offering of Equity Securities is otherwise being offered only to accredited investors. 
 3.3 Board Composition. Each Shareholder hereby agrees to vote, or cause to be voted, all shares of Equity Securities now owned or hereafter acquired by such Shareholder, or over which such
Shareholder has voting control, from time to time and at all times (and attend, in person or by proxy, all meetings of shareholder called for the purpose of electing directors), and agree to take all actions (including, but not limited, to the
nomination of specified persons, the execution of written consents and the calling of a shareholder meeting for the purpose of electing such specified persons) to ensure that the size of the Board shall be set and remain at five (5) directors
and to cause and maintain the election to the Board of the following persons:

representative (the “Observer”) of China Web to attend all meetings of its Board in a nonvoting observer capacity and, in this respect, shall give the Observer copies of all non-executive session notices, minutes, consents and other
materials that it provides to its directors; provided, however, that the Observer shall agree to hold in confidence all information so provided; and, provided further, that the Company reserves the right to withhold any
information and to exclude the Observer from any executive sessions or meetings of the Board or portion thereof if, on the written advice of outside counsel to the Company, the Company in good faith believes that access to such information or
attendance at such executive session or meeting would adversely affect the attorney client privilege between the Company and its counsel and if China Web or its Observer is or is affiliated with a direct competitor of the Company; provided,
that any such exclusion shall be to the minimum extent necessary to address such attorney client privilege. 

3.5 Board Matters. Unless otherwise determined by the vote of a majority of the Directors (including at least one

(45) days from the end of each taxable year of the Company, the Company shall use its commercially reasonable best efforts to determine whether the Company or any of the other Group Companies was a PFIC in such taxable year (including whether
any exception to PFIC status may apply). If the Company determines that the Company or any of the other Group Companies was a PFIC in such taxable year (or if a government authority or any Investor informs the Company that it has so determined), it
shall provide the following information to any Investor that has timely notified the Company that such Investor (or any person or entity holding a direct or indirect interest in such Investor) is a U.S. Person: (i) all information reasonably
available to the Company as an Investor may reasonably request in writing to permit such Investor (or any U.S. Person holding a direct or indirect interest in such Investor) to accurately prepare its U.S. tax returns and comply with any other
reporting requirements, if any, arising from such Investor’s investment in the Company and relating to the Company’s or any of the other Group Companies’ classification as a PFIC, and (ii) a completed “PFIC Annual
Information Statement” in the form of Exhibit C attached hereto as required by Treasury Regulation Section 1.1295-1(g) within 90 days following the end of the Company’s taxable year. 

(c) The Company shall use its commercially reasonable best efforts to comply, and cause each of the other Group Companies
to comply, with all record-keeping, reporting, and other requirements that any Investor informs the Company are necessary to enable the Investor to comply with any applicable U.S. tax rules. The Company shall also use its commercially reasonable
best efforts to provide an Investor with any information reasonably requested by such Investor to enable the Investor to comply with any applicable U.S. tax rules. 

  
 21 









 (d) The cost incurred by the Company in providing the information that it is
required to provide, or is required to cause to be provided, and the cost incurred by the Company in taking the action, or causing the action to be taken, as described in this Section 3.10 shall be borne by the Company. 

3.10 Compliance with Memorandum and Articles. Each party to this Agreement shall take all such actions and shall
do all such things to comply with the Amended Memorandum and the Company’s Amended and Restated Articles of Association (the “Amended Articles”), including but not limited to Section 10 of the Amended Memorandum,
and each holder of Equity Securities that is a party to this Agreement shall vote at any meeting of members, such number of Equity Securities (on an as-converted basis) as may be necessary, or in lieu of any such meeting, shall give such
holder’s written consent, as the case may be, with respect to such number of Equity Securities (on an as-converted basis), to cause the Company to comply with the Amended Articles, including but not limited to Section 10 of the
Amended Memorandum. In the event that the provisions of this Agreement conflict with any provision of the Amended Memorandum or Amended Articles, the provisions of this Agreement shall prevail as between the shareholders of the Company only, who
hereby undertake to take such steps as may be necessary or desirable to amend the Amended Memorandum and Amended Articles to remove such conflict to the fullest extent permitted by applicable laws. 

3.11 D&O Insurance. The Company shall, prior to the consummation of any Initial Public Offering or Qualified
IPO, and thereafter shall maintain, directors’ and officers’ insurance on commercially reasonable and customary terms approved by the Board, including at least one (1) Series A Director, in relation to any person who is or was a
director or an officer of the Company, or who at the request of the Company is or was serving as a director or an officer of, or in any other capacity is or was acting for, another company or a partnership, joint venture, trust or other enterprise,
against any liability asserted against the Person and incurred by the Person in that capacity. The Amended Memorandum and Amended Articles shall at all times provide that the Company shall indemnify the members of the Board to the maximum extent
permitted by the law of the jurisdiction in which the Company is organized. 
 3.12 Confidentiality.

 (a) Disclosure of Terms. Each Party agrees that such Party will keep confidential and will not
disclose, divulge, or use for any purpose any confidential information obtained from any other Party or any of the representatives of such other Party pursuant to the terms of this Agreement, the Amended Articles, the Amended Memorandum and that
certain Right of First Refusal & Co-Sale Agreement entered into by and among the Parties and any other parties thereto on the date hereof (collectively, the “Confidential Information”), except in accordance with the
provisions set forth below. 
 (b) Permitted Disclosures. Notwithstanding the foregoing, the
Company and each of the Shareholders may disclose (i) the Confidential Information to its current or bona fide prospective investors, Affiliates and their respective employees, bankers, lenders, accountants, legal counsels, business partners or

similar to those set forth in this Section 3.12, (ii) such Confidential Information as is required to be disclosed pursuant to routine examination requests from Governmental Authorities with authority to regulate such Party’s
operations, in each case as such Party deems appropriate in good faith, and (iii) the Confidential Information to any Person to which disclosure is approved in writing by the Company and the Shareholders. Any Party hereto may also provide

Section 3.12(b) above, in the event that any Party is requested or becomes legally compelled (including without limitation, pursuant to any applicable tax, securities, other Laws of any jurisdiction, or any applicable stock exchange
rules or regulations) to disclose the existence of this Agreement or any Confidential Information, such party (the “Disclosing Party”) shall provide the other Parties hereto with prompt written notice of that fact and shall consult
with the other Parties hereto regarding such disclosure. At the request of any other Parties, the Disclosing Party shall, to the extent reasonably possible and with the cooperation and reasonable efforts of the other Parties, seek a protective
order, confidential treatment or other appropriate remedy. In any event, the Disclosing Party shall furnish only that portion of the information that is legally required and shall exercise reasonable efforts to obtain reliable assurance that
confidential treatment will be accorded such information. 
 (d) Other Exceptions. Notwithstanding
any other provision of this Section 3.12, the confidentiality obligations of the Parties shall not apply to: (i) information which a restricted party learns from a third party which the receiving party reasonably believes to have
the right to make the disclosure, provided the restricted party complies with any restrictions imposed by the third party; (ii) information which is rightfully in the restricted party’s possession prior to the time of disclosure by the
protected party and not acquired by the restricted party under a confidentiality obligation; or (iii) information which enters the public domain without breach of confidentiality by the restricted party. 

3.13 Termination of Certain Covenants. The covenants set forth in Sections 3.1 to 3.8 shall terminate and be of no
further force or effect upon the consummation of a Qualified IPO or, following any Liquidation Event (as such term is defined in Section 10(A)(2) of the Amended Memorandum), the date on which all monies or other assets distributable to all
holders of Series A Preferred Shares have been distributed in full in compliance with all provisions set forth in Section 10(A)(2) of the Amended Memorandum. 
 4. Drag-Along Right. 
 4.1 Drag-Along Right. In the
event that: 
 (a) the holders of more than fifty percent (50%) of the then outstanding shares of the
Series A Preferred (the “Drag-along Series A Preferred Holders”), voting together as a separate class on an as-converted to Ordinary Shares basis, vote in favor of a Sale Transaction (as defined below); and 

(b) the holders of more than fifty percent (50%) of the then outstanding shares of Ordinary Shares (the
“Drag-along Ordinary Holders,” together with the Drag-along Series A Preferred Holders, the “Drag-along Holders”), voting together as a separate class, vote in favor of a Sale Transaction; 

then each Shareholder hereby agrees with respect to all shares that it holds and any other shares over which it otherwise
exercises dispositive power:

determining the presence of a quorum at such meetings and; (y) to vote (in person, by proxy or by action by written consent, as applicable) all shares in favor of such Sale Transaction and in opposition of any and all other proposals that could
reasonably be expected to delay or impair the ability of the Company to consummate such Sale Transaction; 

  
 23 









 (ii) to refrain from exercising any dissenters’ rights or rights of
appraisal under applicable law at any time with respect to such Sale Transaction; 
 (iii) to execute and
deliver all related documentation and take such other action in support of the Sale Transaction as shall reasonably be requested by the Company; and 
 (iv) not to deposit, and to cause its affiliates not to deposit, except as provided in this Agreement, any voting securities owned by such Shareholder or affiliate in a voting trust or subject any such
voting securities to any arrangement or agreement with respect to the voting of such shares of capital stock, unless specifically requested to do so by the acquirer in connection with a Sale Transaction. 

(c) Notwithstanding Sections 4.1(a) and (b) above, in the event that Alibaba does not vote in favor of any Sale
Transaction, then Alibaba (i) shall have the right to purchase on a pro rata basis from the Drag-along Holders all (but not less than all) of the lesser of (1) the total number of Shares that the purchaser proposed to purchase in the Sale
Transaction and (2) the total number of Shares then held by the Drag-along Holders, (ii) shall have the option, in its sole discretion, to purchase on a pro rata basis from the remaining Shareholders any additional Shares that the
purchaser proposed to purchase in the Sale Transaction but that are not subject to subsection (c)(i) above; and (iii) shall have the right to purchase all or any portion of any remaining Shares, subject to the written agreement of each of the
Shareholders thereof. 
 (d) “Sale Transaction” shall mean any transaction or series of transactions
approved by the Board:

venture, joint stock company, trust or other entity (each, a “Person”) or a group of related Persons, acquires shares representing fifty percent (50%) or more of the outstanding voting power of the Company or shares
representing fifty percent (50%) or more of the outstanding voting power of the Group Companies, or 

(ii) the sale, lease, transfer or other disposition of all or substantially all of the Group Companies’ assets.

 5. Miscellaneous. 
 5.1 Jurisdiction. The registration provisions of this Agreement are drafted primarily in contemplation of an Initial Public Offering in the United States, which the parties recognize may or may not
actually occur. The parties agree as follows: 
 (a) In the event the Company completes an Initial Public
Offering in the United States in the form of American Depositary Receipts (representing American Depositary Shares), rather than Ordinary Shares, the term “Registrable Securities” and the provisions of this Agreement in respect of
Registrable Securities shall apply mutatis mutandis to such American Depositary Receipts, with appropriate adjustments, if any, to give effect to the intention of the parties in such provisions; and 

  
 24 









 (b) In the event the Company does not complete an Initial Public Offering in
the United States, but rather completes an initial public offering of Ordinary Shares, and the listing or admission for quotation of Ordinary Shares on a securities exchange or quotation system, in a jurisdiction outside the United States, the
Company shall use its reasonable best efforts to seek such authorizations, approvals or qualifications, make such filings, effectuate such registrations, and take such other actions as may be reasonably required under the applicable securities laws
and regulations of such jurisdiction and the applicable rules of such securities exchange or quotation system in order for the Holders to be able to freely sell, under such laws and regulations, all or part of their Registrable Securities from time
to time. The foregoing obligations of the Company shall be subject to the terms and conditions of Section 2, applying mutatis mutandis, with appropriate adjustments, if any, to give effect to the intention of the parties in such provisions. The
parties further agree that they will act and cooperate in good faith to give effect to the intention of the parties as provided in Section 2 hereof. 
 5.2 Successors and Assigns. Except as otherwise provided herein, the terms and conditions of this Agreement shall inure to the benefit of and be binding upon the respective successors and assigns
of the parties (including transferees of any shares of Registrable Securities). Nothing in this Agreement, express or implied, is intended to confer upon any party other than the parties hereto or their respective successors and assigns any rights,
remedies, obligations or liabilities under or by reason of this Agreement, except as expressly provided in this Agreement. 
 5.3 Additional Ordinary Holders. In the event that after the date of this Agreement, the Company issues shares of Ordinary Shares, or options to purchase Ordinary Shares, to any employee,
consultant, executive or any third party that will hold at least one percent (1%) of the issued and outstanding Ordinary Shares of the Company following such issuance, the Company shall, as a condition to such issuance, cause such employee,
consultant, executive or applicable third party to execute a counterpart signature page hereto as an Ordinary Holder, and such person shall thereby be bound by, and subject to, all the terms and provisions of this Agreement applicable to an Ordinary
Holder. 
 5.4 Governing Law and Dispute Resolution. 

(a) This Agreement shall be governed by and construed under the laws of the State of New York as applied to agreements
among New York residents entered into and to be performed entirely within New York, without regard to principles of conflict of laws thereunder. 
 (b) Each of the parties hereto irrevocably (i) agrees that any dispute or controversy arising out of, relating to, or concerning any interpretation, construction, performance or breach of this
Agreement, shall be settled by arbitration to be held in Hong Kong under the UNCITRAL Arbitration Rules in accordance with the HKIAC Procedures for the Administration of International Arbitration in force at the date of this Agreement (the
“Arbitration Rules”), (ii) waives, to the fullest extent it may effectively do so, any objection which it may now or hereafter have to the laying of venue of any such arbitration, and (iii) submits to the exclusive

Judgment may be entered on the arbitrator’s decision in any court having jurisdiction. The parties to the arbitration shall each pay an equal share of the costs and expenses of such arbitration, and each party shall separately pay for its
respective counsel fees and expenses. 

  
 25 









 (c) In the event of two or more arbitrations having been commenced under
this Agreement, the tribunal in the arbitration first filed (the “Principal Tribunal”) may in its sole discretion, upon the application of any party to the arbitrations, order that the proceedings be consolidated before the
Principal Tribunal, which will have the jurisdiction to resolve all disputes forming part of the consolidation order, if (i) there are issues of fact and/or law common to the arbitrations, (ii) the interests of justice and efficiency would
be served by such a consolidation, and (iii) no prejudice would be caused to any party in any material respect as a result of such consolidation, whether through undue delay or otherwise. Such application shall be made as soon as practicable
and the party making such application shall give notice to the other parties to the arbitrations. 
 5.5
Counterparts. This Agreement may be executed in two or more counterparts, each of which shall be deemed an original, but all of which together shall constitute one and the same instrument. 

5.6 Titles and Subtitles. The titles and subtitles used in this Agreement are used for convenience only and are
not to be considered in construing or interpreting this Agreement. 
 5.7 Notices. All notices and other

service provider. 
 5.8 Entire Agreement; Amendments and Waivers. This Agreement (including the Exhibits
hereto, if any) constitutes the full and entire understanding and agreement among the parties with regard to the subjects hereof and thereof. Any term of this Agreement may be amended and the observance of any term of this Agreement may be waived
(either generally or in a particular instance and either retroactively or prospectively) only with the written consent of the Company, holders of a majority of the Ordinary Shares voting as a single class, and holders of a majority of the Series A
Preferred voting as a single class on an as-converted basis (including, for so long as it holds at least thirty percent (30%) of the then outstanding Series A Preferred, the written consent of Alibaba). Any amendment or waiver effected in
accordance with this paragraph shall be binding upon each Shareholder, the Company, each future holder of all Ordinary Shares and Series A Preferred. 
 5.9 Severability. If one or more provisions of this Agreement are held to be unenforceable under applicable law, such provision(s) shall be excluded from this Agreement and the balance of the
Agreement shall be interpreted as if such provision(s) were so excluded and shall be enforceable in accordance with its terms. 
 5.10 Specific Performance. The parties hereto acknowledge that, in view of the transactions contemplated by this Agreement, each party would not have an adequate remedy at law for money damages in
the event that this Agreement has not been performed in accordance with its terms, and therefore agrees that the non-breaching parties shall be entitled to specific enforcement of the terms hereof in addition to any other remedy to which such
non-breaching parties may be entitled at law or in equity. 

  
 26

the terms, covenants, or conditions hereof will not be deemed a waiver of such term, covenant, or condition, nor will any waiver or relinquishment of, or failure to insist upon strict compliance with, any right, power or remedy hereunder at any one
or more times be deemed a waiver or relinquishment of such right, power or remedy at any other time or times.

use its reasonable best efforts to take or cause to be taken all action, to do or cause to be done, to execute such further instruments, and to assist and cooperate with the other parties hereto in doing, all things necessary, proper or advisable
under applicable laws or otherwise to consummate and make effective, in the most expeditious manner practicable, the transactions contemplated by this Agreement and, to the extent reasonably requested by another party, to enforce rights and
obligations pursuant hereto. 
 5.13 Attorney’s Fees. In the event that any dispute among the
parties to this Agreement should result in litigation, the prevailing party in such dispute shall be entitled to recover from the losing party all fees, costs and expenses of enforcing any right of such prevailing party under or with respect to this
