 1.2 Request for Registration. 
 (a) Subject to the conditions of this Section 1.2, if the Company shall receive at any time after six (6) months after the effective date of the Initial Offering, a written request from a Tiger Holder or
Tiger Holders or a UCI Holder or UCI Holders of twenty percent (20%) or more of the Registrable Securities then outstanding (the “Initiating Holders”) that the Company file a registration statement under the Act covering the
registration of Registrable Securities with an anticipated aggregate proceeds of at least US$5,000,000, then the Company shall, within twenty (20) days of the receipt thereof, give written notice of such request to all Holders, and subject to
the limitations of this Section 1.2, use all commercially reasonable efforts to effect, as soon as practicable, the registration under the Act of all Registrable Securities that the Holders request to be registered in a written request received
by the Company within twenty (20) days of the mailing of the Company’s notice pursuant to this Section 1.2(a). 
 (b) If the Initiating Holders intend to distribute the Registrable Securities covered by their request by means of an underwriting, they shall so advise the Company as a part of their request made pursuant to this Section 1.2 and the
Company shall include such information in the written notice referred to in Section 1.2(a). In such event the right of any Holder to include its Registrable Securities in such registration shall be conditioned upon such Holder’s
participation in such underwriting and the inclusion of such Holder’s Registrable Securities in the underwriting (unless otherwise mutually agreed by a majority in interest of the Initiating Holders and such Holder) to the extent provided
herein. All Holders proposing to distribute their securities through such underwriting shall enter into an underwriting agreement in customary form with the underwriter or underwriters selected for such underwriting by a majority in interest of the
Initiating Holders (which underwriter or underwriters shall be reasonably acceptable to the Company). Notwithstanding any other provision of this Section 1.2, if the underwriter advises the Company that marketing factors require a limitation on
the number of securities underwritten (including Registrable Securities), then the Company shall so advise all Holders of Registrable Securities that would otherwise be underwritten pursuant hereto, and the number of shares that may be included in
the underwriting shall be allocated to the Holders of such Registrable Securities pro rata based on the number of Registrable Securities held by all such Holders (including the Initiating Holders). In no event shall any Registrable Securities be
excluded from such underwriting unless all other securities are first excluded. Any Registrable Securities excluded or withdrawn from such underwriting shall be withdrawn from the registration. 
  

 59 








 (c) Notwithstanding the foregoing, the Company shall not be required to effect a
registration pursuant to this Section 1.2: 
 (i) in the case of a registration requested by a Tiger Holder, after the
Company has effected two (2) registrations pursuant to this Section 1.2 at the request of Tiger Holders, and such registrations have been declared or ordered effective (and have not been subject to a “stop order” or otherwise
withdrawn); or 
 (ii) in the case of a registration requested by a UCI Holder, after the Company has effected one
(1) registration pursuant to this Section 1.2 at the request of UCI Holders, and such registration has been declared or ordered effective (and has not been subject to a “stop order” or otherwise withdrawn); or 
 (iii) during the period starting with the date sixty (60) days prior to the Company’s good faith estimate of the date of the
filing of and ending on a date one hundred eighty (180) days following the effective date of a Company initiated registration subject to Section 1.3 below, provided that the Company is actively employing in good faith all commercially
reasonable efforts to cause such registration statement to become effective; or 
 (iv) if the Initiating Holders propose to
dispose of Registrable Securities that may be registered on Form F-3 pursuant to Section 1.4 hereof; or 
 (v) if the
Company shall furnish to Holders requesting a registration statement pursuant to this Section 1.2 a certificate signed by the Company’s Chief Executive Officer or Chairman of the Board stating that in the good faith judgment of the Board
of Directors, it would be seriously detrimental to the Company and its shareholders for such registration statement to be effected at such time, in which event the Company shall have the right to defer such filing for a period of not more than
ninety (90) days after receipt of the request of the Initiating Holders, provided that such right shall be exercised by the Company not more than once in any twelve-month period and provided further that the Company shall not register any
securities for the account of itself or any other shareholder during such ninety day period (other than a registration relating solely to the sale of securities of participants in a Company share plan, a registration relating to a corporate
reorganization or transaction under Rule 145 of the Act, a registration on any form that does not include substantially the same information as would be required to be included in a registration statement covering the sale of the Registrable
Securities, or a registration in which the only Ordinary Shares being registered is Ordinary Shares issuable upon conversion of debt securities that are also being registered). 
 1.3 Company Registration. 
 (a) If (but without any obligation to do so) the Company proposes to register (including for this purpose a registration effected by the Company for shareholders other than the Holders) any of its shares or other
securities under the Act in connection with the public offering of such securities (other than a registration relating solely to the sale of securities of participants in a Company share plan, a registration relating to a corporate reorganization or
transaction under Rule 145 of the Act, a registration on any form that does not include substantially the same information as would be required to be included in a registration statement covering the sale of the Registrable Securities, or a
registration in 

  

 60 








 
which the only Ordinary Shares being registered are Ordinary Shares issuable upon conversion of debt securities that are also being registered), the Company
shall, at such time, promptly give each Holder written notice of such registration. Upon the written request of each Holder given within twenty (20) days after mailing of such notice by the Company in accordance with Section 5.8, the
Company shall, subject to the provisions of Section 1.3(c), use all commercially reasonable efforts to cause to be registered under the Act all of the Registrable Securities that each such Holder requests to be registered. 
 (b) Right to Terminate Registration. The Company shall have the right to terminate or withdraw any registration initiated by it
under this Section 1.3 prior to the effectiveness of such registration whether or not any Holder has elected to include securities in such registration. The expenses of such withdrawn registration shall be borne by the Company in accordance
with Section 1.7 hereof. 
 (c) Underwriting Requirements. In connection with any offering involving an
underwriting of the Company’s shares, the Company shall not be required under this Section 1.3 to include any of the Holders’ securities in such underwriting unless they accept the terms of the underwriting as agreed upon between the
Company and the underwriters selected by the Company (or by other persons entitled to select the underwriters) and enter into an underwriting agreement in customary form with such underwriters, and then only in such quantity as the underwriters
determine in their sole reasonable discretion will not jeopardize the success of the offering by the Company. If the total amount of securities, including Registrable Securities, requested by shareholders to be included in such offering exceeds the
amount of securities sold other than by the Company that the underwriters determine in their sole reasonable discretion is compatible with the success of the offering, then the Company shall be required to include in the offering only that number of
such securities, including Registrable Securities, that the underwriters determine in their sole discretion will not jeopardize the success of the offering. In no event shall any Registrable Securities be excluded from such offering unless all other
shareholders’ securities are first excluded. In the event that the underwriters determine that less than all of the Registrable Securities requested to be registered can be included in such offering, then the Registrable Securities that are
included in such offering shall be apportioned pro rata among the selling Holders based on the number of Registrable Securities held by all selling Holders or in such other proportions as shall mutually be agreed to by all such selling Holders.
Notwithstanding the foregoing, in no event shall (i) the amount of securities of the selling Holders included in the offering be reduced below thirty percent (30%) of the total amount of securities included in such offering, unless such
offering is the Qualified Public Offering, in which case the selling Holders may be excluded if the underwriters make the determination described above and no other shareholder’s securities are included in such offering or (ii) any
securities held by an Ordinary Shareholder be included in such offering if any Registrable Securities held by any Holder (and that such Holder has requested to be registered) are excluded from such offering. For purposes of the preceding sentence
concerning apportionment, for any selling shareholder that is a Holder of Registrable Securities and that is a venture capital fund, partnership or corporation, the affiliated venture capital funds, partners, retired partners, members, retired
members and shareholders of such Holder, or the estates and family members of any such partners and retired partners and any trusts for the benefit of any of the foregoing persons shall be deemed to be a single “selling Holder,” and any
pro rata reduction with respect to such “selling Holder” shall be based upon the aggregate amount of Registrable Securities owned by all such related entities and individuals. 
  

 61 








 1.4 Form F-3 Registration. In case the Company shall receive from the Holders of
at least twenty percent (20%) of the Registrable Securities (for purposes of this Section 1.4, the “Initiating Holders”) a written request or requests that the Company effect a registration on Form F-3 and any related
qualification or compliance with respect to all or a part of the Registrable Securities owned by such Holder or Holders, the Company shall: 
 (a) promptly give written notice of the proposed registration, and any related qualification or compliance, to all other Holders; and 
 (b) use all commercially reasonable efforts to effect, as soon as practicable, such registration and all such qualifications and
compliances as may be so requested and as would permit or facilitate the sale and distribution of all or such portion of such Holders’ Registrable Securities as are specified in such request, together with all or such portion of the Registrable
Securities of any other Holders joining in such request as are specified in a written request given within fifteen (15) days after receipt of such written notice from the Company, provided, however, that the Company shall not be obligated to
effect any such registration, qualification or compliance, pursuant to this section 1.4: 
 (i) if Form F-3 is not available
for such offering by the Holders; 
 (ii) if the Holders, together with the holders of any other securities of the Company
entitled to inclusion in such registration, propose to sell Registrable Securities and such other securities (if any) at an aggregate price to the public (net of any underwriters’ discounts or commissions) of less than US$1,000,000; 

(iii) if the Company shall furnish to Holders requesting a registration statement pursuant to this Section 1.4 a certificate
signed by the Company’s Chief Executive Officer or Chairman of the Board stating that in the good faith judgment of the Board of Directors, it would be seriously detrimental to the Company and its shareholders for such registration statement to
be effected at such time, in which event the Company shall have the right to defer such filing for a period of not more than ninety (90) days after receipt of the request of the Initiating Holders, provided that such right shall be exercised by
the Company not more than once in any twelve-month period and provided further that the Company shall not register any securities for the account of itself or any other shareholder during such ninety (90) day period (other than a registration
relating solely to the sale of securities of participants in a Company shares plan, a registration relating to a corporate reorganization or transaction under Rule 145 of the Act, a registration on any form that does not include substantially the
same information as would be required to be included in a registration statement covering the sale of the Registrable Securities, or a registration in which the only Ordinary Shares being registered are Ordinary Shares issuable upon conversion of
debt securities that are also being registered); or 
 (iv) if the Company has, within the twelve (12) month period
preceding the date of such request, already effected two registrations on Form F-3 for the Holders pursuant to this Section 1.4. 
 (c) If the Initiating Holders intend to distribute the Registrable Securities covered by their request by means of an underwriting, they shall so advise the Company as a part of their request made pursuant to this
Section 1.4 and the Company shall include such information in the written notice referred to in Section 1.4(a). The provisions of Section 1.2(b) shall be applicable to such request (with the substitution of Section 1.4 for
references to Section 1.2). 
  

 62 








 (d) Subject to the foregoing, the Company shall file a registration statement covering
the Registrable Securities and other securities so requested to be registered as soon as practicable after receipt of the request or requests of the Initiating Holders. Registrations effected pursuant to this Section 1.4 shall not be counted as
requests for registration effected pursuant to Sections 1.2. 
 1.5 Obligations of the Company. Whenever required under
this Section 1 to effect the registration of any Registrable Securities, the Company shall, as expeditiously as reasonably possible: 
 (a) prepare and file with the SEC a registration statement with respect to such Registrable Securities and use all commercially reasonable efforts to cause such registration statement to become effective, and, upon
the request of the Holders of a majority of the Registrable Securities registered thereunder, keep such registration statement effective for a period of up to one hundred twenty (120) days or, if earlier, until the distribution contemplated in
the Registration Statement has been completed; 
 (b) prepare and file with the SEC such amendments and supplements to such
registration statement and the prospectus used in connection with such registration statement as may be necessary to comply with the provisions of the Act with respect to the disposition of all securities covered by such registration statement;

 (c) furnish to the Holders such number of copies of a prospectus, including a preliminary prospectus, in conformity with
the requirements of the Act, and such other documents as they may reasonably request in order to facilitate the disposition of Registrable Securities owned by them; 
 (d) use all commercially reasonable efforts to register and qualify the securities covered by such registration statement under such other
securities or Blue Sky laws of such jurisdictions as shall be reasonably requested by the Holders, provided that the Company shall not be required in connection therewith or as a condition thereto to qualify to do business or to file a general
consent to service of process in any such states or jurisdictions; 
 (e) in the event of any underwritten public offering,
enter into and perform its obligations under an underwriting agreement, in usual and customary form, with the managing underwriter of such offering; 
 (f) notify each Holder of Registrable Securities covered by such registration statement at any time when a prospectus relating thereto is required to be delivered under the Act 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; 
 (g) cause all such Registrable Securities registered
pursuant to this Section 1 to be listed on a national exchange or trading system and on each securities exchange and trading system on which similar securities issued by the Company are then listed; and 
  

 63 








 (h) provide a transfer agent and registrar for all Registrable Securities registered
pursuant to this Agreement and a CUSIP number for all such Registrable Securities, in each case not later than the effective date of such registration. 
 Notwithstanding the provisions of this Section 1, the Company shall be entitled to postpone or suspend, for a reasonable period of time (provided that such right shall be exercised by the Company not more than
once in any twelve (12) month period) the filing, effectiveness or use of, or trading under, any registration statement if the Company shall determine that any such filing or the sale of any securities pursuant to such registration statement
would, in the good faith judgment of the Board of Directors: 
 (i) materially impede, delay or interfere with any material
pending or proposed financing, acquisition, corporate reorganization or other similar transaction involving the Company for which the Board of Directors has authorized negotiations; 
 (ii) materially adversely impair the consummation of any pending or proposed material offering or sale of any class of securities by the
Company; or 
 (iii) require disclosure of material nonpublic information that, if disclosed at such time, would be
materially harmful to the interests of the Company and its shareholders; provided, however, that during any such period all executive officers and directors of the Company are also prohibited from selling securities of the Company (or
any security of any of the Company’s subsidiaries or affiliates). 
 In the event of the suspension of effectiveness of any registration
statement pursuant to this Section 1.5, the applicable time period during which such registration statement is to remain effective shall be extended by that number of days equal to the number of days during which the effectiveness of such
registration statement was suspended. 
 1.6 Information from Holder. It shall be a condition precedent to the
obligations of the Company to take any action pursuant to this Section 1 with respect to the Registrable Securities of any selling Holder that such Holder shall furnish to the Company such information regarding itself, the Registrable
Securities held by it, and the intended method of disposition of such securities as shall be reasonably required to effect the registration of such Holder’s Registrable Securities. 
 1.7 Expenses of Registration. All expenses other than underwriting discounts and commissions incurred in connection with
registrations, filings or qualifications pursuant to Sections 1.2, 1.3 and 1.4, including (without limitation) all registration, filing and qualification fees, printers’ and accounting fees, fees and disbursements of counsel for the Company and
the reasonable fees and disbursements of one counsel for the selling Holders, shall be borne by the Company. Notwithstanding the foregoing, the Company shall not be required to pay for any expenses of any registration proceeding begun pursuant to
Section 1.2 or Section 1.4 if the registration request is subsequently withdrawn at the request of the Holders of eighty percent (80%) of the Registrable Securities to be registered (in which case all participating Holders shall bear
such expenses pro rata based upon the number of 

  

 64 








 
Registrable Securities that were to be included in the withdrawn registration), unless, in the case of a registration requested under Section 1.2, the
Initiating Holders agree to forfeit their right to one demand registration pursuant to Section 1.2 and provided, however, that if at the time of such withdrawal, the Holders have learned of a material adverse change in the
condition, business or prospects of the Company from that known to the Holders at the time of their request and have withdrawn the request with reasonable promptness following disclosure by the Company of such material adverse change, then the
Holders shall not be required to pay any of such expenses and shall retain their rights pursuant to Sections 1.2 and 1.4. 
 1.8 Delay of Registration. No Holder shall have any right to obtain or seek an injunction restraining or otherwise delaying any such registration as the result of any controversy that might arise with respect to the interpretation or
implementation of this Section 1. 
 1.9 Indemnification. In the event any Registrable Securities are included in
a registration statement under this Section 1: 
 (a) To the extent permitted by law, the Company will indemnify and hold
harmless each Holder, the partners, members, officers, directors and shareholders of each Holder, legal counsel and accountants for each Holder, any underwriter (as defined in the Act) for such Holder and each person, if any, who controls such
Holder or underwriter within the meaning of the Act or the 1934 Act, against any losses, claims, damages or liabilities (joint or several) to which they may become subject under the Act, the 1934 Act, any state securities laws or any rule or
regulation promulgated under the Act, insofar as such losses, claims, damages, or liabilities (or actions in respect thereof) arise out of or are based upon any of the following statements, omissions or violations (collectively a
“Violation”): (i) any untrue statement or alleged untrue statement of a material fact contained in such registration statement, including any preliminary prospectus or final prospectus contained therein or any amendments or
supplements thereto, (ii) the omission or alleged omission to state in such registration statement a material fact required to be stated therein, or necessary to make the statements therein not misleading or (iii) any violation or alleged
violation by the Company of the Act, the 1934 Act, any state securities laws or any rule or regulation promulgated under the Act, the 1934 Act or any state securities laws, and the Company will reimburse each such Holder, underwriter, controlling
person or other aforementioned person for any legal or other expenses reasonably incurred by them in connection with investigating or defending any such loss, claim, damage, liability or action as such expenses are incurred; provided, however, that
the indemnity agreement contained in this subsection l.9(a) shall not apply to amounts paid in settlement of any such loss, claim, damage, liability or action if such settlement is effected without the consent of the Company (which consent shall not
be unreasonably withheld), nor shall the Company be liable in any such case for any such loss, claim, damage, liability or action to the extent that it arises out of or is based upon a Violation 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, controlling person or other aforementioned person; provided further, however, that the foregoing indemnity agreement with respect
to any preliminary prospectus shall not inure to the benefit of any Holder or underwriter or other aforementioned person, or any person controlling such Holder or underwriter, from whom the person asserting any such losses, claims, damages or
liabilities purchased shares in the offering, if a copy of the most current prospectus was not sent or given by or on behalf of such Holder or underwriter or 
  

 65 








 
other aforementioned person to such person, if required by law to have been so delivered, at or prior to the written confirmation of the sale of the shares
to such person, and if the prospectus (as so amended or supplemented) would have cured the defect giving rise to such loss, claim, damage or liability. 
 (b) To the extent permitted by law, each selling Holder will indemnify and hold harmless the Company, each of its directors, each of its officers who has signed the registration statement, each person, if any, who
controls the Company within the meaning of the Act, legal counsel and accountants for the Company, any underwriter, any other Holder selling securities in such registration statement and any controlling person of any such underwriter or other
Holder, against any losses, claims, damages or liabilities (joint or several) to which any of the foregoing persons may become subject, under the Act, the 1934 Act, any state securities laws or any rule or regulation promulgated under the Act, the
1934 Act or any state securities laws, insofar as such losses, claims, damages or liabilities (or actions in respect thereto) arise out of or are based upon any Violation, in each case to the extent (and only to the extent) that such Violation
occurs in reliance upon and in conformity with written information furnished by such Holder expressly for use in connection with such registration; and each such Holder will reimburse any person intended to be indemnified pursuant to this subsection
l.9(b) for any legal or other expenses reasonably incurred by such person in connection with investigating or defending any such loss, claim, damage, liability or action as such expenses are incurred; provided, however, that the indemnity agreement
contained in this subsection l.9(b) shall not apply to amounts paid in settlement of any such loss, claim, damage, liability or action if such settlement is effected without the consent of the Holder (which consent shall not be unreasonably
withheld), and provided that in no event shall any indemnity under this subsection l.9(b) exceed the net proceeds from the offering received by such Holder. 
 (c) Promptly after receipt by an indemnified party under this Section 1.9 of notice of the commencement of any action (including any
governmental action), such indemnified party will, if a claim in respect thereof is to be made against any indemnifying party under this Section 1.9, deliver to the indemnifying party a written notice of the commencement thereof and the
indemnifying party shall have the right to participate in and, to the extent the indemnifying party so desires, jointly with any other indemnifying party similarly noticed, to assume the defense thereof with counsel mutually satisfactory to the
parties; provided, however, that an indemnified party (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 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 liability to the indemnified party under this Section 1.9, but the omission to so deliver written notice to the indemnifying party will not relieve it of any liability that it may have to any indemnified party otherwise
than under this Section 1.9. 
 (d) If the indemnification provided for in this Section 1.9 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, 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 

  

 66 








 
expense in such proportion as is appropriate to reflect the relative fault of the indemnifying party on the one hand and 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; provided, however, that no contribution by any Holder, when combined with
any amounts paid by such Holder pursuant to Section 1.9(b), shall exceed the net proceeds from the offering received by such Holder. The relative fault of the indemnifying party and the indemnified party shall be determined by reference to,
among other things, whether the untrue or alleged untrue statement of a material fact or the omission or alleged 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. 
 (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 conflict with the
foregoing provisions, the provisions in the underwriting agreement shall control. 
 (f) The obligations of the Company and
Holders under this Section 1.9 shall survive the completion of any offering of Registrable Securities in a registration statement under this Section 1 and otherwise. 
 1.10 Reports Under the 1934 Act. With a view to making available to the Holders the benefits of Rule 144 and any other rule or
regulation of the SEC that may at any time permit a Holder to sell securities of the Company to the public without registration or pursuant to a registration on Form F-3, the Company agrees to: 
 (a) make and keep public information available, as those terms are understood and defined in Rule 144, at all times after the effective
date of the Initial Offering; 
 (b) file with the SEC in a timely manner all reports and other documents required of the
Company under the Act and the 1934 Act; and 
 (c) furnish to any Holder, so long as the Holder owns any Registrable
Securities, forthwith upon request (i) a written statement by the Company that it has complied with the reporting requirements of Rule 144 (at any time after ninety (90) days after the effective date of the first registration statement
filed by the Company), the Act and the 1934 Act (at any time after it has become subject to such reporting requirements), or that it qualifies as a registrant whose securities may be resold pursuant to Form F-3 (at any time after it so qualifies),
(ii) a copy of the most recent annual or quarterly report of the Company and such other reports and documents so filed by the Company, and (iii) such other information as may be reasonably requested to avail any Holder of any rule or
regulation of the SEC that permits the selling of any such securities without registration or pursuant to such form. 
 1.11
Assignment of Registration Rights. The rights to cause the Company to register Registrable Securities pursuant to this Section 1 may be assigned (but only with all related obligations) by a Holder to a transferee or assignee of such
securities that is permitted under this Agreement 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 

  

 67 








 
assignee and the securities with respect to which such registration rights are being assigned; (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 1.13 below; and (c) such assignment shall be effective only if immediately following such transfer the further
disposition of such securities by the transferee or assignee is restricted under the Act. 
 1.12 Limitations on Subsequent
Registration Rights. From and after the date of this Agreement, the Company shall not, without the prior written consent of the Holders of eighty percent (80%) of the Registrable Securities, enter into any agreement with any holder or
prospective holder of any securities of the Company that would allow such holder or prospective holder (a) to include any of such securities in any registration filed under Section 1.2, Section 1.3 or Section 1.4 hereof, 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 or (b) to demand registration of their securities. 
 1.13 “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 Initial Offering and ending on the date specified by the Company and the managing underwriter (such period not to exceed one hundred eighty (l80) days)
(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
Ordinary Shares or any securities convertible into or exercisable or exchangeable for Ordinary Shares (whether such shares or any such securities are then owned by the Shareholder or are thereafter acquired), 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. The foregoing provisions of this Section 1.13 shall apply only to the Initial Offering of equity securities, shall not apply to the sale of any shares to an underwriter pursuant to an
underwriting agreement, and shall only be applicable to the Shareholders if all officers, directors and greater than one percent (1%) shareholders of the Company enter into similar agreements. The underwriters in connection with the Initial
Offering are intended third party beneficiaries of this Section 1.13 and shall have the right, power and authority to enforce the provisions hereof as though they were a party hereto. Each Shareholder further agrees to execute such agreements
as may be reasonably requested by the underwriters in the Initial Offering that are consistent with this Section 1.13 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 Shareholders subject to such agreements pro rata based on the number of shares subject to such agreements. 
 1.14 Termination of Registration Rights. No Holder shall be entitled to exercise any right provided for in this Section 1
(i) after five (5) years following the consummation of the Qualified Public Offering or (ii) as to any Holder, such earlier time after the Qualified Public Offering at which such Holder (A) can sell all shares held by it in
compliance with Rule 144(k) or (B) holds one percent (1%) or less of the Company’s 

  

 68 








 
outstanding Ordinary Shares and all Registrable Securities held by such Holder (together with any affiliate of the Holder with whom such Holder must
aggregate its sales under Rule 144) can be sold in any three-month period without registration in compliance with Rule 144. 
 2.
Covenants of the Company. 
 2.1 Delivery of Financial Statements. The Company shall, upon request, deliver to
each Shareholder (or transferee of the Shareholder provided the transfer of securities to such transferee is permitted under this Agreement) that holds at least 1.8% of all the Ordinary Shares Equivalents in issue and outstanding or each Noteholder
(together with its affiliates) holding Notes with an aggregate principal amount of not less than US$5,000,000 (a “Major Investor”), with respect to itself and its subsidiaries on a consolidated basis: 
 (a) as soon as practicable, but in any event within ninety (90) days after the end of each fiscal year of the Company, consolidated
financial statements, including an income statement for such fiscal year, a balance sheet and statement of shareholders’ equity as of the end of such year, and a statement of cash flows for such year, such year end financial reports to be in
reasonable detail, prepared in accordance with generally accepted accounting principles (“GAAP”), and audited and certified by independent public accountants of recognized standing in the PRC and internationally selected by the
Company; 
 (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, an unaudited consolidated income statement, statement of cash flows for such fiscal quarter and an unaudited balance sheet as of the end of such fiscal quarter; 
 (c) within thirty (30) days of the end of each month, an unaudited consolidated income statement and statement of cash flows and

as prepared, any other budgets or revised budgets prepared by the Company; 
 (e) with respect to the financial statements
called for in subsections (b) and (c) of this Section 2.1, an instrument executed by the Chief Financial Officer or President of the Company certifying that such financials were prepared in accordance with GAAP consistently applied
with prior practice for earlier periods (with the exception of footnotes that may be required by GAAP) and fairly present the financial condition of the Company and its results of operation for the period specified, subject to year end audit
adjustment; and 
 (f) such other information relating to the financial condition, business or corporate affairs of the
Company as the Investors may from time to time reasonably request (including, but not limited to, a capitalization table provided annually), provided, however, that the Company shall not be obligated under this subsection (f) or any other
subsection of Section 2.1 to provide information that it deems in good faith to be a trade secret or similar confidential information. 
  

 69 








 2.2 Inspection. The Company shall permit each Major Investor, at such Major
Investor’s expense, to visit and inspect the Company’s and any of its subsidiaries’ properties, to examine their books of account and records and to discuss the Company’s and any of its subsidiaries’ affairs, finances and
accounts with its officers, all at such reasonable times as may be requested by the Major Investors; provided, however, that the Company shall not be obligated pursuant to this Section 2.2 to provide access to any information that it reasonably
considers to be a trade secret or similar confidential information. 
 2.3 Right of First Offer. Subject to the terms
and conditions specified in this Section 2.3, the Company hereby grants to each Shareholder a right of first offer with respect to future sales by the Company of its Shares (as hereinafter defined). For purposes of this Section 2.3, the
term “Shareholder” includes any partners, members and affiliates of a Shareholder. A Shareholder shall be entitled to apportion the right of first offer hereby granted it among itself and its partners, members and affiliates in such
proportions as it deems appropriate, provided, however, that such partner, member or affiliate of that Shareholder who is not a party to this Agreement shall not be allotted or issued any Shares unless and until it has delivered to the Company a
duly executed Deed of Adherence. For purposes of this Section 2.3, “affiliates” means any person that (i) Tiger or UCI (as the case may be) controls or manages, directly or indirectly, whether by possessing the power to direct or
cause the direction of the management policies of such an affiliate, through the ownership of voting securities, by contract, credit arrangement or proxy, as trustee, executor, agent or otherwise, (ii) is under common control with Tiger or UCI
(as the case may be) or (iii) controls, directly or indirectly, Tiger or UCI (as the case may be). 
 Each time the Company proposes to
offer any shares of, or securities convertible into or exchangeable or exercisable for any shares of, any class of the Company’s shares (“Shares”), the Company shall first make an offering of such Shares to each Shareholder in
accordance with the following provisions: 
 (a) The Company shall deliver a notice in accordance with Section 5.5
(“Notice”) to the Shareholders stating (i) its bona fide intention to offer such Shares, (ii) the number of such Shares to be offered and (iii) the price and terms upon which it proposes to offer such Shares.

 (b) By written notification received by the Company within twenty-five (25) calendar days after receipt of the Notice,
each Shareholder may elect to purchase or obtain, at the price and on the terms specified in the Notice, up to that portion of such Shares that equals the proportion that the number of Ordinary Shares Equivalents held by such Shareholder (assuming
full conversion and exercise of all convertible and exercisable securities then outstanding) bears to the total number of Ordinary Shares Equivalents then outstanding (assuming full conversion and exercise of all convertible and exercisable
securities then outstanding). The Company shall promptly, in writing, inform each Shareholder that elects to purchase all the shares available to it (a “Fully Exercising Shareholder”) of any other Shareholder’s failure to do
likewise. During the ten (10) day period commencing after such information is given, each Fully Exercising Shareholder may elect to purchase that portion of the Shares for which Shareholders were entitled to subscribe but which were not
subscribed for by the Shareholders that is equal to the proportion that the number of Ordinary Shares Equivalents held by such Fully Exercising Shareholder (assuming full conversion and exercise of all convertible and exercisable securities then
outstanding) bears to the total number of Ordinary Shares Equivalents then outstanding (assuming full conversion and exercise of all convertible and exercisable securities then outstanding). 
  

 70 








 (c) If all Shares that Shareholders are entitled to obtain pursuant to subsection 2.3(b)
are not elected to be obtained as provided in subsection 2.3(b) hereof, the Company may, during the ninety (90) day period following the expiration of the period provided in subsection 2.3(b) hereof, offer the remaining unsubscribed portion of
such Shares to any person or persons at a price not less than that, and upon terms no more favorable to the offeree than those, specified in the Notice, provided, however, that no Shares shall be allotted or issued to such offeree unless and until
such offeree has delivered to the Company a duly executed Deed of Adherence as a condition precedent to any such offer. If the Company does not enter into an agreement for the sale of the Shares within such period, or if such agreement is not
consummated within sixty (60) days of the execution thereof, the right provided hereunder shall be deemed to be revived and such Shares shall not be offered unless first reoffered to the Shareholders in accordance herewith. 
 (d) The right of first offer in this Section 2.3 shall not be applicable to (i) Ordinary Shares issued pursuant to a share split
or similar reorganization; (ii) Ordinary Shares issued or issuable upon conversion of a Note; (iii) securities issued in connection with a bona fide business acquisition by the Company; (iv) securities issued or issuable pursuant to
strategic transactions entered into for primarily non-equity financing purposes; (v) securities issued or issuable pursuant to equipment lease financings or bank credit arrangements entered into for primarily non-equity financing purposes; or
(vi) any securities offered in a Qualified Public Offering. 
 2.4 Actions Requiring Investors Consent. The
Company shall not, without the prior written approval of the Holders of a majority of the then outstanding Registrable Securities, amend, waive or otherwise modify any provision of a service agreement or non-competition agreement with a Key
Management Person (as defined in the Subscription Agreement). 
 3. Restrictions on Transfer of Equity Securities. 
 3.1 Definitions. 
 (a) Delivery. For purposes of this Section 3, the term “Delivery” shall have the meaning set forth in Section 5.8 below. 
 (b) Equity Securities. For purposes of this Section 3, the term “Equity Securities” shall mean any securities now or
hereafter owned or held by a Holder (or a transferee in accordance with Section 3.5 herein) having voting rights in the election of the Board of Directors, or any securities evidencing an ownership interest in the Company, or any securities
convertible into or exercisable for any of the foregoing including, without limitation, the Notes. 
 (c) Holders. For
purposes of this Section 3, the term “Holders” shall mean the Investors and the Ordinary Shareholders or persons who have acquired shares from the Investors or the Ordinary Shareholders or their transferees or assignees in accordance
with the provisions of this Agreement. 
  

 71 








 (d) Majority Ordinary Shareholders. For purposes of this Section 3, the terms
“Majority Ordinary Shareholders” shall mean Mr. Yu Jianqiu, Mr. Chen Zihong and Mr. Chen Gonghao and a “Majority Ordinary Shareholder” shall mean any of them. 
 (e) Parties. For purposes of this Agreement, the term “Parties” shall mean the Company, the Investors and the Ordinary
Shareholders. 
 (f) Transfer. For purposes of this Section 3, the term “Transfer” shall include any
sale, assignment, encumbrance, hypothecation, pledge, conveyance in trust, gift, transfer by bequest, devise or descent, or other transfer or disposition of any kind, including, but not limited to, transfers pursuant to divorce or legal separation,
transfers to receivers, levying creditors, trustees or receivers in bankruptcy proceedings or general assignees for the benefit of creditors, whether voluntary, involuntarily or by operation of law, directly or indirectly, of any of the Equity
Securities. 
 3.2 Rights of Refusal. 
 (a) Transfer Notice. If at any time a Holder proposes to Transfer Equity Securities (a “Selling Holder”), then the
Selling Holder shall promptly give the Company and each other Holder (a “Remaining Holder”) written notice of the Selling Holder’s intention to make the Transfer (the “Transfer Notice”). The Transfer Notice
shall include (i) a description of the Equity Securities to be transferred (“Offered Shares”), (ii) the name(s) and address(es) of the prospective transferee(s), (iii) the consideration and (iv) the material
terms and conditions upon which the proposed Transfer is to be made. The Transfer Notice shall certify that the Selling Holder has received a firm offer from the prospective transferee(s) and in good faith believes a binding agreement for the
Transfer is obtainable on the terms set forth in the Transfer Notice. The Transfer Notice shall also include a copy of any written proposal, term sheet or letter of intent or other agreement relating to the proposed Transfer. In the event that the
transfer is being made pursuant to the provisions of Section 3.5, the Transfer Notice shall state under which specific subsection the Transfer is being made. 
 (b) Company’s Right of First Refusal. The Company shall have an option for a period of ten (10) days from Delivery of the
Transfer Notice to elect to purchase the Offered Shares at the same price and subject to the same material terms and conditions as described in the Transfer Notice. The Company may exercise such purchase option and purchase all or any portion of the
Offered Shares by notifying the Selling Holder in writing before expiration of such ten (10) day period as to the number of such shares that it wishes to purchase. If the Company gives the Selling Holder notice that it desires to purchase such
shares, then payment for the Offered Shares shall be by check or wire transfer, against delivery of the Offered Shares to be purchased at a place agreed upon between the parties and at the time of the scheduled closing therefor, which shall be no
later than forty-five (45) days after Delivery to the Company of the Transfer Notice, unless the Transfer Notice contemplated a later closing with the prospective third party transferee(s) or unless the value of the purchase price has not yet
been established pursuant to Section 3.2(e). If the Company fails to purchase any or all of the Offered Shares by exercising the option granted in this Section 3.2(b) within the period provided, the remaining Offered Shares shall be
subject to the options granted to the Remaining Holders pursuant to subsection 3.2(d). 
  

 72 








 (c) Additional Transfer Notice. Subject to the Company’s option set forth in
Section 3.2(b), if at any time the Selling Holder proposes a Transfer, then, within five (5) days after the Company has declined to purchase all, or a portion, of the Offered Shares or the Company’s option to so purchase the Offered
Shares has expired, the Selling Holder shall give each Remaining Holder an “Additional Transfer Notice” that shall include all of the information and certifications required in a Transfer Notice and shall additionally identify the
Offered Shares that the Company has declined to purchase (the “Remaining Shares”) and briefly describe the Remaining Holders’ rights of first refusal and co-sale rights with respect to the proposed Transfer. 
 (d) Remaining Holders’ Right of First Refusal. (i) Each Remaining Holder shall have an option for a period of fifteen
(15) days from the Delivery of the Additional Transfer Notice from the Selling Holder set forth in Section 3.2(c) to elect to purchase its respective pro rata share of the Remaining Shares at the same price and subject to the same material
terms and conditions as described in the Additional Transfer Notice. Each Remaining Holder may exercise such purchase option and purchase all or any portion of his, her or its pro rata share of the Remaining Shares (a “Participating
Holder” for the purposes of Section 3.2 (d) and 3.2 (e)), by notifying the Selling Holder and the Company in writing, before expiration of the fifteen (15) day period as to the number of such shares that he, she or it wishes
to purchase (the “Participating Holder Notice”). Each Remaining Holder’s pro rata share of the Remaining Shares shall be a fraction of the Remaining Shares, the numerator of which shall be the number of Ordinary Shares
Equivalents (as defined in Section 1.1) owned by such Remaining Holder on the date of the Transfer Notice and denominator of which shall be the total number of Ordinary Shares Equivalents (as defined in Section 1.1) held by all Remaining
Holders on the date of the Transfer Notice. 
 (ii) In the event any Remaining Holder elects not to purchase its pro rata
share of the Remaining Shares available pursuant to its option under subsection 3.2(d)(i) within the time period set forth therein, then the Selling Holder shall promptly give written notice (the “Overallotment Notice”) to each
Participating Holder that has elected to purchase all of its pro rata share of the Remaining Shares (each a “Fully Participating Holder”), which notice shall set forth the number of Remaining Shares not purchased by the other Remaining
Holders, and shall offer the Participating Holders the right to acquire the unsubscribed shares. Each Participating Holder shall have five (5) days after Delivery of the Overallotment Notice to deliver a written notice to the Selling Holder
(the “Participating Holders Overallotment Notice”) of its election to purchase its pro rata share of the unsubscribed shares on the same terms and conditions as set forth in the Additional Transfer Notice and indicating the maximum number
of the unsubscribed shares that it will purchase in the event that any other Fully Participating Holder elects not to purchase its pro rata share of the unsubscribed shares. For purposes of this Section 3.2(d)(ii), the numerator shall be the
same as that used in Section 3.2(d)(i) above and the denominator shall be the total number of Ordinary Shares Equivalents (as defined in Section 1.1) owned by all Participating Holders on the date of the Transfer Notice. Each Participating
Holder shall be entitled to apportion Remaining Shares to be purchased among its partners and affiliates (including in the case of a venture capital fund other venture capital funds affiliated with such fund), provided that such Participating Holder
notifies the Selling Holder of such allocation. 
 (e) Payment. (i) The Participating Holders shall effect the
purchase of the Remaining Shares with payment by check or wire transfer, against delivery of the Remaining Shares to be purchased at a place agreed upon between the parties and at the time of the scheduled closing therefor, which shall be no later
than forty-five (45) days after Delivery to the Company of the Transfer Notice, unless the Transfer Notice contemplated a later closing with the prospective third party transferee(s) or unless the value of the purchase price has not yet been
established pursuant to Section 3.2(e). 
  

 73 








 (ii) Should the purchase price specified in the Transfer Notice or Additional Transfer
Notice be payable in property other than cash or evidences of indebtedness, the Company (and the Participating Holders) shall have the right to pay the purchase price in the form of cash equal in amount to the fair market value of such property. If
the Selling Holder and the Company (or the Participating Holders) cannot agree on such cash value within ten (10) days after Delivery to the Company of the Transfer Notice (or the Delivery of the Additional Transfer Notice to the Remaining
Holders), the valuation shall be made by an appraiser of recognized standing selected by the Selling Holder and the Company (or the Participating Holders) or, if they cannot agree on an appraiser within twenty (20) days after Delivery to the
Company of the Transfer Notice (or the Delivery of the Additional Transfer Notice to the Holders), each shall select an appraiser of recognized standing and those appraisers shall designate a third appraiser of recognized standing, whose appraisal
shall be determinative of such value. The cost of such appraisal shall be shared equally by the Selling Holder and the Company (and the Participating Holders), with half of the cost borne by the Company and the Participating Holders pro rata by
each, based on the number of shares such parties have expressed an interest in purchasing pursuant to this Section 3.2. If the time for the closing of the Company’s purchase or the Participating Holders’ purchase has expired but the
determination of the value of the purchase price offered by the prospective transferee(s) has not been finalized, then such closing shall be held on or prior to the fifth business day after such valuation shall have been made pursuant to this
subsection. 
 3.3 Right of Co-Sale. 
 (a) In the case of a transfer by any of the Majority Ordinary Shareholders (the “Selling Ordinary Shareholder”), to the
extent the Company and the Remaining Holders do not exercise their respective rights of refusal as to all of the Offered Shares pursuant to Section 3.2, then each Holder other than the Selling Ordinary Shareholder (a “Co-Sale Holder”
for purposes of this Section 3.3) that notifies the Selling Ordinary Shareholder in writing within twenty (20) days after Delivery of the Additional Transfer Notice referred to in Section 3.2(c), shall have the right to participate in
such sale of Equity Securities on the same terms and conditions as specified in the Transfer Notice. Such Co-Sale Holder’s notice to the Selling Ordinary Shareholder shall indicate the number of shares of the Company that the Co-Sale Holder
wishes to sell under his, her or its right to participate. To the extent one or more of the Holders exercise such right of participation in accordance with the terms and conditions set forth below, the number of shares of Equity Securities that the
Selling Ordinary Shareholder may sell in the Transfer shall be correspondingly reduced. 
 (b) Each Co-Sale Holder may sell
all or any part of that number of shares of the Company equal to the product obtained by multiplying (i) the aggregate number of shares of Equity Securities covered by the Transfer Notice that have not been subscribed for pursuant to
Section 3.2 by (ii) a fraction, the numerator of which is the number of Ordinary Shares (including Ordinary Shares issuable upon conversion of the Note) owned by the Co-Sale Holder on the date of the Transfer Notice and the denominator of
which is the total number of Ordinary Shares (including Ordinary Shares issuable upon conversion of the Note) owned by the Selling Ordinary Shareholder and all of the Co-Sale Holders on the date of the Transfer Notice. 
  

 74 








 (c) Each Co-Sale Holder shall effect its participation in the sale by promptly delivering
to the Selling Ordinary Shareholder for transfer to the prospective purchaser one or more certificates, properly endorsed for transfer, which represent: 
 (i) the number of Ordinary Shares that such Co-Sale Holder elects to sell; or 
 (ii) that
number of Equity Securities that are at such time convertible into the number of Ordinary Shares that such Co-Sale Holder elects to sell; provided, however, that if the prospective third-party purchaser objects to the delivery of Equity Securities
in lieu of Ordinary Shares, such Co-Sale Holder shall convert such Equity Securities into Ordinary Shares and deliver Ordinary Shares as provided in this Section 3.3. The Company agrees to make any such conversion concurrent with the actual
transfer of such shares to the purchaser and contingent on such transfer. 
 (d) The share certificate or certificates that
the Co-Sale Holder delivers to the Selling Ordinary Shareholder pursuant to Section 3.3(c) shall be transferred to the prospective purchaser in consummation of the sale of the Equity Securities pursuant to the terms and conditions specified in
the Transfer Notice, and the Selling Ordinary Shareholder shall concurrently therewith remit to such Co-Sale Holder that portion of the sale proceeds to which such Co-Sale Holder is entitled by reason of its participation in such sale. To the extent
that any prospective purchaser or purchasers prohibits such assignment or otherwise refuses to purchase shares or other securities from a Co-Sale Holder exercising its rights of co-sale hereunder, the Selling Ordinary Shareholder shall not sell to
such prospective purchaser or purchasers any Equity Securities unless and until, simultaneously with such sale, the Selling Ordinary Shareholder shall purchase such shares or other securities from such Co-Sale Holder for the same consideration and
on the same terms and conditions as the proposed transfer described in the Transfer Notice. 
 3.4 Non-Exercise of
Rights. To the extent that the Company and the Remaining Holders have not exercised their rights to purchase the Offered Shares or the Remaining Shares within the time periods specified in Section 3.2 and, with respect to transfers by a
Majority Ordinary Shareholder, the Co-Sale Holders have not exercised their rights to participate in the sale of the Remaining Shares within the time periods specified in Section 3.3, the Selling Holder shall have a period of thirty
(30) days from the expiration of such rights in which to sell the Offered Shares or the Remaining Shares, as the case may be, upon terms and conditions (including the purchase price) no more favorable than those specified in the Transfer
Notice, to the third-party transferee(s) identified in the Transfer Notice. The third party transferee(s) shall acquire the Offered Shares and the Remaining Shares free and clear of subsequent rights of first refusal and co-sale rights under this
Agreement, provided, however, that no Selling Holder may sell or transfer its Equity Securities under Section 3.2 unless and until such transferee(s) have delivered to the Company a duly executed Deed of Adherence (as defined in
Section 1.1) as a condition precedent to any such Transfer. In the event the Selling Holder does not consummate the sale or disposition of the Offered Shares and Remaining Shares within the thirty (30) day period from the expiration of
these rights, the Company’s first refusal rights, the Remaining Holders’ first refusal rights and, with respect to transfers by Majority Ordinary Shareholders, the Co-Sale Holder’s co-sale rights shall continue to be applicable to any
subsequent disposition of the Offered Shares or the Remaining Shares by the Selling Holder until such right lapses in accordance with the terms of this Agreement. Furthermore, the exercise or non exercise of the rights of the 

  

 75 








 
Company, the Holders and the Co-Sale Holders under this Section 3 to purchase Equity Securities from the Selling Holder or participate in sales of
Equity Securities by the Selling Ordinary Shareholder shall not adversely affect their rights to make subsequent purchases from the Selling Holder of Equity Securities or subsequently participate in sales of Equity Securities by the Selling Ordinary
Shareholder. 
 3.5 Limitations to Rights of Refusal and Co-Sale. Notwithstanding the provisions of Sections 3.2 and
3.3 of this Agreement, the first refusal rights of the Company, the first refusal rights of the Remaining Holders and the co-sale rights of the Co-Sale Holders shall not apply to: 
 (a) the Transfer of Equity Securities to any spouse or member of Holder’s immediate family, or to a custodian, trustee (including a
trustee of a voting trust), executor, or other fiduciary for the account of the Holder’s spouse or members of the Holder’s immediate family, or to a trust for the Holder’s own self, or a charitable remainder trust;

Transfer. Such transferred Equity Securities shall remain “Equity Securities” hereunder, and such pledgee, transferee or donee shall be treated as the “Holder” for purposes of this Agreement.

shall not be recognized by the Company. 
 (b) In the event that a Majority Ordinary Shareholder should sell any Equity

shall have the put option provided below under subsection (c), and all the Majority Ordinary Shareholders shall be bound by the applicable provisions of such option. 
 (c) In the event of a Prohibited Transfer, each Co-Sale Holder shall have the right to sell to the Majority Ordinary Shareholders the type
and number of shares of Equity Securities equal to the number of shares each Co-Sale Holder would have been entitled to transfer to the third-party transferee(s) under Section 3.3 hereof had the Prohibited Transfer been effected pursuant to and
in compliance with the terms hereof. Such sale shall be made on the following terms and conditions:

share at which the shares are to be sold to the Majority Ordinary Shareholders shall be equal to the price per share paid by the third-party transferee(s) to the Majority Ordinary Shareholders in the Prohibited Transfer. The Majority Ordinary

3.6(c)(i), in cash or by other means acceptable to the Holder.
