(b) If, after receiving a Demand Notice, the Company furnishes to the Initiating Holder a certificate signed by a director of the Company
stating that, in the good faith judgment of the board of directors of the Company, it would be materially interfere with a bona fide business, acquisition or divestiture or financing transaction of the Company or is reasonably likely to require

Registration Statement to be in the form of a firm commitment underwritten offering and the managing underwriters for such offering shall be internationally reputable investment banking firms selected by the Holder who has delivered the Underwriting
Election and reasonably acceptable to the Company.

	3.	PIGGYBACK REGISTRATIONS. 

 3.1 Registration of the Company’s
Securities. Subject to Section 3.3 hereof, if the Company proposes to Register for its own account any of its Securities, or for the account of any holder of Securities any of such holder’s Securities, in connection with
the public offering of such Securities (including in respect of a Registration under Section 2.1 or a “takedown” of a Shelf Registration Statement under Section 2.3), the Company shall promptly give each Holder
written notice of such Registration and, upon the written request of any Holder given within fifteen (15) days after delivery of such notice, the Company shall use its reasonable best efforts to include in such Registration any Registrable
Securities thereby requested by such Holder. If a Holder decides not to include all or any of its or its Affiliates’ Registrable Securities in such Registration 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 upon the terms and conditions set forth herein. 

3.2 Right to Terminate Registration. The Company shall have the right to terminate or withdraw any Registration that was initiated by it under
Section 3.1 prior to the effectiveness of such Registration, whether or not any Holder has elected to participate therein. The expenses of such withdrawn Registration shall be borne by the Company in accordance with
Section 4.3. 
 3.3 Underwriting Requirements. 

(a) In connection with any offering involving an underwriting of the Company’s Securities, the Company shall not be required to Register
the Registrable Securities of a Holder under this Section 3 unless such Holder’s Registrable Securities are included in the underwriting and such Holder enters into an underwriting agreement in customary form with the underwriters
and setting forth such terms for the underwriting. In the event the underwriters advise the Holders seeking Registration of Registrable Securities pursuant to this Section 3 in writing that market factors (including the aggregate number
of Registrable Securities requested to be Registered, the general condition of the market, and the status of the Persons proposing to sell securities pursuant to the Registration) require a limitation of the number of Securities to be underwritten,
the underwriters may exclude some or all Registrable Securities from the Registration and underwriting, and the number of Securities and Registrable Securities that may be included in the Registration and the underwriting shall be allocated in the
following order of priority: first, to the Company if such Registration has been initiated by the Company or to the Holder and its Affiliates who delivered the Underwriting Election if such underwriting is being undertaken pursuant to
Section 2.4, and second, to each Holder requesting inclusion of its Registrable Securities in such Registration Statement on a pro rata basis based on the respective amounts of Securities which such Holders would otherwise
be entitled to include in the Registration; provided that the right of the underwriters to exclude Securities and Registrable Securities from the Registration and underwriting as described above shall be restricted so that all other
Securities that are not (i) Registrable Securities or (ii) if such Registration has been initiated by the Company, the Securities to be Registered by the Company for its own account, shall first be excluded from such Registration and
underwriting before any Registrable Securities of the Holders are so excluded; provided, further, unless such underwriting is being undertaking pursuant to Section 2.4, the number of the Registrable Securities held by Holders that
are included in an underwriting must not be reduced below thirty percent (30%) of the total number of Registrable Securities requested by Holders to be included in the Registration. 

  
 5 








 (b) If any Holder disapproves of the terms of any underwriting, such Holder may elect to withdraw
therefrom by written notice to the Company and the underwriters delivered at least ten (10) days prior to the effective date of the Registration Statement. Any Registrable Securities excluded or withdrawn from the underwriting shall be
withdrawn from the Registration. 
 3.4 Exempt Registration. The Company shall have no obligation to Register any Registrable Securities under
this Section 3 in connection with an Exempt Registration. 
 3.5 Not a Demand Registration. Registration pursuant to this
Section 3 shall not be deemed to be a Registration as described in Section 2.1 hereof. There shall be no limit on the number of times the Holders may participate in Registration of Registrable Securities under this
Section 3. 
  

	4.	PROCEDURES. 

 4.1 Registration Procedures and Obligations. Whenever required under
this Agreement to effect the Registration of any Registrable Securities held by the Holders, the Company shall, as expeditiously as possible: 

(a) prepare and file with the Commission a Registration Statement with respect to those Registrable Securities and use its reasonable best
efforts to cause that Registration Statement to become effective, and, keep the Registration Statement effective and current for such period of time as is necessary to permit the sale of the Registrable Securities thereunder; provided,
however, that before filing such Registration Statement or any amendments thereto, the Company will furnish to the counsel selected by the Holders copies of all such documents proposed to be filed; 

(b) prepare and file with the Commission amendments and supplements to that Registration Statement and the prospectus or prospectus supplement
used in connection with the Registration Statement as may be necessary to comply with the provisions of U.S. Securities Law with respect to the disposition of all securities covered by the Registration Statement;

reasonably requested by the Holders or underwriters; provided that the Company shall not be required to qualify to do business or file a general consent to service of process in any such jurisdictions; and provided, further, that in
the event any jurisdiction in which the securities shall be qualified imposes a non-waivable requirement that expenses incurred in connection with the qualification of the securities be borne by the selling shareholders, those expenses shall be
payable by such selling shareholders on a pro rata basis; 

  
 6 








 (e) in the event of any underwritten public offering, enter into and perform its obligations
under an underwriting agreement in customary form (including indemnification provisions and procedures customary in underwritten offerings) and take all such other actions reasonably requested by the underwriters to expedite or facilitate the
underwritten disposition of such Registrable Securities (including making its officers and management team available for investor road shows, sales events, marketing activities and other meetings) and in connection therewith in any underwritten
offering, (i) make such representations and warranties to the underwriters and the Holders with respect to the business of the Company and its subsidiaries, and the Registration Statement, prospectus and documents incorporated or deemed to be

opinions requested in underwritten offerings, (iii) use its reasonable best efforts to obtain “comfort” letters from the independent certified public accountants of the Company (and, if necessary, any other independent certified
public accountants of any business acquired by the Company for which financial statements or financial data are included in the Registration Statement) who have certified the financial statements included in the Registration Statement, addressed to
the underwriters, such letters to be in customary form and covering matters of the type customarily covered in “comfort” letters and (iv) deliver such documents and certificates as may be reasonably requested by the Holders of the
Registrable Securities being sold in connection therewith, their counsel and the underwriters to evidence the continued validity of the representations and warranties made pursuant to clause (i) above and to evidence compliance with any
customary conditions contained in the underwriting agreement or other agreement entered into by the Company; 
 (f) promptly notify each
Holder: (i) when the Registration Statement, the prospectus or any prospectus supplement related thereto or post-effective amendment to the Registration Statement has been filed, and, with respect to the Registration Statement or any
post-effective amendment thereto, when the same has become effective; (ii) of any request by the Commission for amendments or supplements to the Registration Statement or the prospectus used in connection with the Registration Statement or any
additional information; (iii) of the issuance by the Commission of any stop order suspending the effectiveness of the Registration Statement or the initiation of any proceedings by any Person for that purpose; and (iv) of the receipt by
the Company of any written notification with respect to the suspension of the qualification of any Registrable Securities for sale in any jurisdiction or the initiation or overt threat of any proceeding for such purpose; 

(g) notify each Holder, at any time when a prospectus relating thereto is required to be delivered under U.S. Securities Laws, of 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 and promptly prepare a post-effective amendment to such Registration Statement or a supplement to the related prospectus and file any other required document, and
prepare and furnish to the Holders and underwriters a reasonable number of copies of a supplement to or an amendment of such prospectus as may be necessary, so that, as thereafter delivered to the Holders and any underwriters, the prospectus will
not contain an untrue statement of a material fact or omit to state any material fact required to be stated therein or necessary to make the statements therein not misleading in the light of the circumstances then existing; 

  
 7 








 (h) use its reasonable best efforts to prevent the issuance or obtain the withdrawal of any order
suspending the effectiveness of any Registration Statement at the earliest practicable time; 
 (i) if any such Registration Statement refers
to any Holder by name or otherwise as the holder of any securities of the Company, and if such Holder is advised by counsel that it is or may be deemed to be a control person in relation to, or an Affiliate of, the Company, then such Holder shall
have the right to require (i) the insertion therein of language, in form and substance satisfactory to such Holder, to the effect that the holding by such Holder is not to be construed as a recommendation by such Holder of the investment
quality of the Company’s securities covered thereby and that such holding does not imply that such Holder will assist in meeting any future financial requirements of the Company, or (ii) in the event that such reference to such Holder by
name or otherwise is not, based on the advice of the counsels to the Company, such Holder and if applicable, the underwriters, required by the Securities Act or any similar federal statute then in force, the deletion of the reference to such Holder;

 (j) if requested by any Holder of Registrable Securities being registered and/or sold in connection therewith, or the underwriters,

filings of such prospectus supplement or such amendment as soon as practicable after the Company’s receipt of such request;

Registrable Securities, in each case not later than the effective date of the Registration;

Holders, any underwriters participating in any disposition pursuant to a Registration Statement and any attorneys or accountants or other agents retained by any such underwriters or selected by the Holders, all financial and other records, pertinent
corporate documents, and properties of the Company, and cause the Company’s officers, directors, employees, and independent accountants to supply all information reasonably requested by any such Holder, underwriters, attorneys, accountants, or
agents, in each case, as necessary or advisable to verify the accuracy of the information in such Registration Statement and to conduct appropriate due diligence in connection therewith; 

(m) use its reasonable best efforts to cause the transfer agent to remove restrictive legends on certificates representing the securities
covered by such Registration Statement, as appropriate and settle any offering or sale of Registrable Securities, including with respect to the transfer of physical stock certificates into book-entry form in accordance with any procedures reasonably
requested by the Holders or underwriters; 

  
 8 








 (n) cooperate with the Holders and the underwriters to facilitate the timely delivery of

officers, directors, partners, members, managers, shareholders, accountants, attorneys, agents and employees of each such controlling person, each underwriter, if any, and each Person who controls (within the meaning of Section 15 of the

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 (each 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
in the Registration Statement, including any preliminary prospectus or final prospectus contained therein or any amendments or supplements thereto, 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 U.S. Securities Laws, or any rule or regulation promulgated under U.S. Securities Laws. The Company will reimburse any Person intended to be indemnified pursuant to this
Section 5.1 for any legal or other expenses reasonably incurred by them in connection with investigating or defending any such loss, claim, damage, liability or action. 

(b) The indemnity agreement contained in this Section 5.1 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 or delayed), nor shall the Company be liable for any such loss, claim, damage, liability or action to the
extent that it arises out of or is based upon a Violation that occurs in reliance upon and in conformity with written information furnished expressly for use in connection with such Registration by any such Holder, underwriter or controlling Person.

 (c) The foregoing indemnity of the Company is subject to the condition that, insofar as they relate to any defect in a preliminary
prospectus but such defect has been eliminated or remedied in the amended prospectus on file with the Commission at the time the applicable Registration becomes effective (the “Final Prospectus”), such indemnity shall not inure to
the benefit of any Person if a copy of the Final Prospectus was timely furnished to the Holder or underwriter and was not furnished to the Person asserting the loss, liability, claims or damages at or prior to the time such action is required by the
Securities Act. 
 5.2 Holder Indemnity. 

(a) To the extent permitted by applicable Law, each Holder that has included Registrable Securities in a Registration will, severally and not
jointly, indemnify and hold harmless the Company, each Person who controls the Company (within the meaning of Section 15 of the Securities Act and Section 20 of the Exchange Act) and each their respective officers, directors, partners,
members, managers, shareholders, accountants, attorneys, agents and employees from and against all losses, claims, costs, damages or liabilities (whether joint or several) to which any of the foregoing Persons may become subject, under U.S.
Securities Laws or otherwise, insofar as such losses, claims, damages or liabilities (or actions in respect thereto) arise out of or are based on any untrue statement (or alleged untrue statement) of a material fact contained in any such
Registration Statement, including any preliminary prospectus or final prospectus contained therein or any amendments or supplements thereto, 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, and will reimburse any Person intended to be indemnified pursuant to this Section 5.2 for any legal or any other expenses reasonably incurred by them in connection with
investigating or defending any such claim, loss, damage, liability or action, in each case to the extent, but only to the extent, that such untrue statement (or alleged untrue statement) or omission (or alleged omission) is made in such Registration
Statement, including any preliminary prospectus or final prospectus contained therein or any amendments or supplements thereto, in reliance upon and in conformity with written information furnished to the Company and signed by such Holder and
intended to be specifically for use therein. 

  
 10 








 (b) The indemnity contained in this Section 5.2 shall not apply to amounts paid in
settlement of any such loss, claim, damage, liability or action if such settlement is effected without the consent of such Holder (which consent shall not be unreasonably withheld), and in no event shall the aggregate indemnity under this
Section 5.2 (including any reimbursement of any expenses) exceed the net proceeds (less underwriting discounts and selling commissions) from the offering received by such Holder. A Holder will not be required to enter into any agreement
or undertaking in connection with any Registration providing for any indemnification or contribution on the part of such Holder greater than the Holder’s obligations under this Section 5.2. 

5.3 Notice of Indemnification Claim. Promptly after receipt by an indemnified party under Section 5.1 or Section 5.2 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 Section 5.1 or Section 5.2, 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 notified, to
assume the defense thereof with counsel reasonably satisfactory to the indemnifying party. An indemnified party (together with all other indemnified parties that may be represented without conflict by one counsel) shall have the right to retain one
separate counsel, with the reasonably incurred fees and expenses to be paid by the indemnifying party, if representation of such indemnified party by the counsel retained by the indemnifying party would be inappropriate due to actual or potential
differing interests between such indemnified party and any other party represented by such counsel in such proceeding. The failure to deliver written notice to the indemnifying party within a reasonable time of the commencement of any such action,
if prejudicial to its ability to defend such action, shall relieve such indemnifying party of any liability to the indemnified party under this Section 5, but the omission to deliver written notice to the indemnifying party will not relieve
it of any liability that it may have to any indemnified party otherwise than under this Section 5. 
 5.4 Contribution. If any indemnification
provided for in Section 5.1 or Section 5.2 is held by a court of competent jurisdiction to be unavailable to an indemnified party with respect to any loss, liability, claim, damage or expense referred to herein, 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 hand, 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. The parties hereto agree that it would not be just and equitable if contribution pursuant to this Section 5.4 were determined by pro rata allocation or by any other method of allocation that does not take account of the
equitable considerations referred to in the immediately preceding paragraph. Notwithstanding the provisions of this Section 5.4, an indemnifying party that is a Holder shall not be required to contribute any amount in excess of the
amount that such indemnifying party has otherwise been, or would otherwise be, required to pay pursuant to Section 5.2 by reason of such untrue or alleged untrue statement or omission or alleged omission.

Holders, enter into any agreement with any holder or prospective holder of any Securities that would (i) grant such holder or prospective holder any registration rights more favorable to such holder or prospective holder than those rights
granted pursuant to this Agreement, (ii) allow such holder or prospective holder to demand Registration of their securities, unless under the terms of such agreement, such holder or prospective holder may demand such Securities in any such
Registration only to the extent that the demand of such securities will not reduce the amount of the Registrable Securities of the Holders that are demanded or (iii) allow such holder or prospective holder to include such securities in any
Registration filed under Section 2.3, Section 2.4 or Section 3, unless under the terms of such agreement such holder or prospective holder may include such Securities in any such Registration only to the extent that
the inclusion of such securities will not reduce the amount of the Registrable Securities of the Holders that are included.

other reports filed by the Company with the Commission or any other relevant securities exchange, regulatory authority or government agency and copies of annual reports to shareholders or other materials delivered to any holders of Securities of the
Company, provided that the obligations under this Section 6.4 shall be deemed to be satisfied to the extent such reports and other materials have been filed in a public database maintained by the Commission, or such other relevant

 14 








 7.4 Public Announcements. Except as required by Law or by the requirements of any securities exchange on
which the securities of a party are listed, no party to this Agreement shall make, or cause to be made, any press release or public announcement in respect of this Agreement or otherwise communicate with any news media without the prior written
consent of the other party hereto, and the parties shall cooperate as to the timing and contents of any such press release or public announcement. 
 7.5
Cumulative Remedies. The rights and remedies provided by this Agreement are cumulative and the use of any one right or remedy by any party shall not preclude or waive its right to use any or all other remedies. The said rights and remedies are
given in addition to any other rights the parties may have by law, statute, ordinance or otherwise. 
 7.6 Binding Effect. This Agreement shall be
binding upon and inure to the benefit of all of the parties and, to the extent permitted by this Agreement, their successors, executors, administrators, heirs, legal representatives and assigns. 

7.7 Severability. If any term or other provision of this Agreement is invalid, illegal or incapable of being enforced by any Law or public policy, all
other terms and provisions of this Agreement shall nevertheless remain in full force and effect for so long as the economic or legal substance of the transactions contemplated by this Agreement is not affected in any manner materially adverse to any
party hereto. Upon such determination that any term or other provision is invalid, illegal or incapable of being enforced, the parties hereto shall negotiate in good faith to modify this Agreement so as to effect the original intent of the parties
hereto as closely as possible in a mutually acceptable manner in order that the transactions contemplated by this Agreement are consummated as originally contemplated to the greatest extent possible. 

7.8 Entire Agreement. This Agreement, together with the Shareholders’ Agreement, constitutes the entire agreement of the parties hereto with
respect to the subject matter hereof as of the date hereof and supersedes all prior agreements and undertakings, both written and oral, among the parties hereto with respect to the subject matter hereof. 

7.9 Governing Law. This Agreement shall be governed by and construed in accordance with the laws of Hong Kong, without regard to the conflicts of laws
rules stated therein. 
 7.10 Dispute Resolution. Any dispute, controversy or claim arising out of or relating to this Agreement, including, but not
limited to, any question regarding the breach, termination or invalidity thereof shall be finally resolved by arbitration in Hong Kong in accordance with the rules (the “ICC Rules”) of the International Chamber of Commerce (the
“ICC”) in force at the time of commencement of the arbitration. 

  
 15 








 (a) The arbitral tribunal shall consist of three arbitrators. The arbitrators shall be appointed
in accordance with the ICC Rules. 
 (b) The language to be used in the arbitration proceedings shall be English. 

(c) Any arbitration award shall be (i) in writing and shall contain the reasons for the decision, (ii) final and binding on the
parties hereto and (iii) enforceable in any court of competent jurisdiction, and the parties hereto agree to be bound thereby and to act accordingly. 

(d) The parties hereto expressly consent to the consolidation of arbitration proceedings commenced hereunder with arbitration proceedings
commenced pursuant to the arbitration agreements contained in the Shareholders’ Agreement. In addition, the parties hereto expressly agree that any disputes arising out of or in connection with this Agreement and the Shareholders’
Agreement concern the same transaction or series of transactions. 
 (e) In the event a dispute is referred to arbitration hereunder, the
parties hereto shall continue to exercise their remaining respective rights and fulfill their remaining respective obligations under this Agreement. 

(f) It shall not be incompatible with this arbitration agreement for any party to seek interim or conservatory relief from courts of competent
jurisdiction before the constitution of the arbitral tribunal. 
 7.11 Specific Performance. The parties hereto acknowledge and agree that the parties
hereto would be irreparably damaged if any of the provisions of this Agreement are not performed in accordance with their specific terms or are otherwise breached and that any non-performance or breach of this Agreement by any party hereto could not
be adequately compensated by monetary damages alone and that the parties hereto would not have any adequate remedy at law. Accordingly, in addition to any other right or remedy to which any party hereto may be entitled, at law or in equity
(including monetary damages), such party shall be entitled to enforce any provision of this Agreement by a decree of specific performance and to temporary, preliminary and permanent injunctive relief to prevent breaches or threatened breaches of any
of the provisions of this Agreement without posting any bond or other undertaking. 
 7.12 Severability. If any term, provision, covenant or
restriction of this Agreement is held by a court of competent jurisdiction to be invalid, void or unenforceable, the remainder of the terms, provisions, covenants and restrictions of this Agreement shall remain in full force and effect and shall in
no way be affected, impaired or invalidated so long as the economic or legal substance of the transactions contemplated hereby is not affected in any manner materially adverse to any party. Upon such a determination, the parties shall negotiate in
good faith to modify this Agreement so as to effect the original intent of the parties as closely as possible in an acceptable manner in order that the transactions contemplated hereby be consummated as originally contemplated to the fullest extent
possible. 

  
 16 








 7.13 Expenses. Except to the extent provided otherwise herein, all costs and expenses, including fees and
disbursements of counsel, financial advisors and accountants, incurred in connection with this Agreement and the transactions contemplated hereby shall be paid by the party incurring such costs and expenses. 

7.14 Amendments and Waivers. 
 (a) Any
provision of this Agreement may be amended or waived if, and only if, such amendment or waiver is in writing and signed, in the case of an amendment, by the parties hereto or, in the case of a waiver, by the party or parties against whom the waiver
is to be effective. 
 (b) Any party to this Agreement may in accordance with subclause (a) above, (i) extend the time for the
performance of any of the obligations or other acts of the other party; or (ii) waive compliance with any of the agreements of the other party or conditions to such obligations contained herein. Notwithstanding the foregoing, no failure or
delay by any party hereto in exercising any right hereunder shall operate as a waiver thereof nor shall any single or partial exercise thereof preclude any other or future exercise of any other right hereunder. The failure of any party hereto to
assert any of its rights hereunder shall not constitute a waiver of any of such rights. 
 7.15 No Third Party Beneficiaries. This Agreement shall be
binding upon and inure solely to the benefit of, and be enforceable by, only the parties hereto and their respective successors and permitted assigns and nothing herein, express or implied, is intended to or shall confer upon any other Person (other
than an indemnified party solely with respect to Section 5) any right, benefit or remedy of any nature whatsoever, including any rights of employment for any specified period, under or by reason of this Agreement. 

7.16 Construction. Each party hereto acknowledges and agrees it has had the opportunity to draft, review and edit the language of this Agreement and
that no presumption for or against any party arising out of drafting all or any part of this Agreement will be applied in any controversy, claim or dispute relating to, in connection with or involving this Agreement. Accordingly, the parties hereto
hereby waive the benefit of any rule of Law or any legal decision that would require, in cases of uncertainty, that the language of a contract should be interpreted most strongly against the party who drafted such language. 

7.17 Counterparts. This Agreement may be executed and delivered (including by facsimile or other means of electronic transmission, such as by electronic
mail in “pdf” form) in one or more counterparts, and by the different parties hereto in separate counterparts, each of which when executed shall be deemed to be an original, but all of which taken together shall constitute one and the same
agreement.
