	 	(2)	each of the parties set forth in Exhibit A hereto (each, a “Purchaser”, and collectively, the “Purchasers”). The Purchasers on the one hand, and the Company on the other hand,
are sometimes herein referred to each as a “Party,” and collectively as the “Parties.” 

W I T N E S S E T H: 

WHEREAS, the Company has filed a registration statement on Form F-1 on April 2, 2014 (as may be amended from time to time, the
“Registration Statement”) with the United States Securities and Exchange Commission (the “SEC”) in connection with the initial public offering (the “Offering”) by the Company of American Depositary
Shares (“ADS”) representing Class A ordinary shares (“Ordinary Shares”) of the Company as specified in the Registration Statement; and 

WHEREAS, the Purchasers wish to invest in the Company by acquiring Ordinary Shares in the Company in a transaction exempt from registration
pursuant to Regulation S (“Regulation S”) of the U.S. Securities Act of 1933, as amended (the “Securities Act”); 
 NOW,
THEREFORE, in consideration of the foregoing recitals and the mutual promises hereinafter set forth, the Parties hereto agree as follows: 

ARTICLE I 
 PURCHASE AND
SALE 
 Section 1.1 Issuance, Sale and Purchase of Ordinary Shares. Upon the terms and subject to the conditions of
this Agreement, each Purchaser hereby severally but not jointly agrees to purchase, and the Company hereby agrees to issue, sell and deliver to each Purchaser, at the Closing (as defined below), the number of Ordinary Shares determined pursuant to
Section 1.2 with respect to such Purchaser (collectively, the “Purchased Shares”) at a price per Ordinary Share equal to the Offer Price (as defined below), free and clear of all liens or encumbrances (except for restrictions
arising under the Securities Act or created by virtue of this Agreement or the Lock-up Agreement (as defined below)). The “Offer Price” means the price per ADS set forth on the cover of the Company’s final prospectus in

Shares pursuant to Section 1.1 shall take place concurrently with the closing of the Offering at the same offices for the closing of the Offering or at such other place as the Company and any Purchaser may mutually agree with respect to such
Purchaser’s Purchased Shares. Two business days prior to the Closings, the Company shall issue a notice to each Purchaser specifying the aggregate consideration to be paid by such Purchaser for the Ordinary Shares being purchased (such
Purchaser’s “Purchase Price”), which shall in no case be greater than the maximum purchase price set forth opposite such Purchaser’s name in Exhibit A hereto. The total number of the Ordinary Shares that each
Purchaser shall purchase as Purchased Shares at the Closing shall be equal to the quotient of the Purchaser’s Purchase Price divided by the Offer Price; provided, however, that (i) no fractional shares of Ordinary Shares will
be issued as Purchased Shares, (ii) any fractions shall be rounded down to the nearest whole number of Ordinary Shares, and (iii) each Purchaser’s Purchase Price will be reduced by the value of any such fractional share (as calculated
on the basis of the Offer Price). The date and time of the Closings are referred to herein as the “Closing Date.” For the avoidance of doubt and notwithstanding anything to the contrary herein, the Closings of each Purchaser of its
respective Purchased Shares shall not be conditional on each other, and the relevant parties shall be obligated to consummate each such Closing with respect to a Purchaser to the extent all applicable terms and conditions hereunder have been
satisfied with respect thereto. 
 (b) Payment and Delivery. At the Closings, each Purchaser shall severally but not jointly pay and

the Company, and the Company shall deliver one or more duly executed share certificates in original form, registered in the name of such Purchaser, together with a certified true copy of the register of the members of the Company, evidencing the
Purchased Shares being issued and sold to such Purchaser.

Section 4.2 Third Party Claims. 

(a) If any third party shall notify any Indemnified Party in writing with respect to any matter involving a claim by such third party (a

Claim, and upon delivery of such notice by the Indemnifying Party, the Indemnifying Party shall have the right to fully control and settle the proceeding, provided, that, any such settlement or compromise shall be permitted hereunder only with the
written consent of the Indemnified Party. 
 (c) If requested by the Indemnifying Party, the Indemnified Party shall, at the sole cost and
expense of the Indemnifying Party, cooperate with the Indemnifying Party and its counsel in contesting any Third Party Claim which the Indemnifying Party elects to contest, including the making of any related counterclaim against the person
asserting the Third Party Claim or any cross complaint against any person. The Indemnified Party shall have the right to receive copies of all pleadings, notices and communications with respect to any Third Party Claim, other than any privileged
communications between the Indemnifying Party and its counsel, and shall be entitled, at its sole cost and expense, to retain separate co-counsel and participate in, but not control, any defense or settlement of any Third Party Claim assumed by the
Indemnifying Party pursuant to Section 4.2(b). 
 (d) In the event of a Third Party Claim for which the Indemnifying Party
elects not to assume the defense or fails to make such an election within the 30 days of the Claim Notice, the Indemnified Party may, at its option, defend, settle, compromise or pay such action or claim at the expense of the Indemnifying Party;
provided, that, any such settlement or compromise shall be permitted hereunder only with the written consent of the Indemnifying Party, which consent shall not be unreasonably withheld or delayed. 

Section 4.3 Other Claims. In the event any Indemnified Party should have a claim against the Indemnifying Party hereunder
which does not involve a Third Party Claim, the Indemnified Party shall promptly transmit to the Indemnifying Party a written notice (the “Indemnity Notice”) describing in reasonable detail the nature of the claim, the Indemnified
Party’s best estimate of the amount of Losses attributable to such claim and the basis of the Indemnified Party’s request for indemnification under this Agreement. If the Indemnifying Party does not notify the Indemnified Party within
thirty (30) days from its receipt of the Indemnity Notice that the Indemnifying Party disputes such claim, the Indemnifying Party shall be deemed to have accepted and agreed with such claim. 

Section 4.4 Cap. Notwithstanding the foregoing, the Indemnifying Party shall have no liability (for indemnification or
otherwise) with respect to any Losses in excess of the applicable Purchase Price.

	2.	Registration Rights. 

 2.1 Piggyback Registrations. 

 

	 	(a)	The Company shall notify each Investor in writing at least thirty (30) days prior to filing any Registration Statement under the Securities Act for purposes of effecting a public offering of securities of the
Company (including Registration Statements relating to secondary offerings of securities of the Company, but excluding Registration Statements filed in connection with the IPO, under Section 2.2 of this Agreement or relating to any employee
benefit plan or a corporate reorganization), and shall afford each Investor an opportunity to include in such Registration Statement all or any part of the Registrable Securities then held by such Investor to the extent provided herein. If an
Investor desires to include in any such Registration Statement all or any part of the Registrable Securities held by it, it shall within twenty (20) days after receipt of the above-described notice from the Company so notify the Company in
writing and in such notice shall inform the Company of the number of Registrable Securities such Investor wishes to include in such Registration Statement. If such Investor decides not to include all of its Registrable Securities in any Registration
Statement thereafter filed by the Company, such Investor shall nevertheless continue to have the right to include any Registrable Securities in any subsequent Registration Statement or Registration Statements as may be filed by the Company with
respect to offerings of its securities, all upon the terms and conditions set forth herein. 

  

	 	(b)	Underwriting. If a Registration Statement under which the Company gives notice under this Section 2.1 is for an underwritten offering, then the Company shall so advise each Investor. In such event, the right
of any of an Investor’s Registrable Securities to be included in a Registration pursuant to this Section 2.1 shall be conditioned upon such Investor’s participation in such underwriting and the inclusion of such Investor’s
Registrable Securities in the underwriting to the extent provided herein. If an Investor proposes to distribute its Registrable Securities through such underwriting it shall enter into an underwriting agreement in customary form with the managing
underwriter or underwriters selected for such underwriting. If the managing underwriter(s) determine(s) in good faith that marketing factors require a limitation of the number of Ordinary Shares to be underwritten, then the managing underwriter(s)
may exclude any or all Ordinary Shares held by the Investors from the Registration and the underwriting. If an Investor disapproves of the terms of any such underwriting, such Investor may elect to withdraw therefrom by written notice to the Company
and the underwriter(s), delivered at least ten (10) Business Days prior to the effective date of the Registration Statement. Any Registrable Securities excluded or withdrawn from such underwriting shall be excluded and withdrawn from the
Registration. 

  

	 	(c)	No Limit on Number of Piggyback Registrations. There shall be no limit on the number of times the Investors may request Registration of Registrable Securities under this Section 2.1. 

  
 3 

 2.2 Form F-3 Registration. 

 

	 	(a)	In case the Company shall receive from an Investor 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 any part of the
Registrable Securities owned by such Investor, then the Company shall promptly give written notice of the proposed Registration and such Investor’s request therefor, and any related qualification or compliance, to all other Holders; and,
subject to the provisions of this Sections 2.2(b) and (c), as soon as practicable but in no later than forty-five (45) days after receipt of the request of such Investor, effect such Registration and all such qualifications and compliances as
may be so requested and as would permit or facilitate the sale and distribution of such Registrable Securities of such Investor 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. 

  

	 	(b)	Notwithstanding anything to the contrary provided above, the Company shall not be obligated to effect any such Registration, qualification or compliance pursuant to this Section 2.2: 

 

	 	(1)	if Form F-3 is not available for such offering by the Holders; 

  

	 	(2)	if such 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 (before payment of any underwriters’ discounts or commissions) of less than US$20,000,000; 

  

	 	(3)	if the Company shall furnish to the Investor requesting such Registration a certificate signed by the Chairman of the Board of Directors of the Company stating that in the good faith judgment of the Board of Directors
of the Company, it would be materially detrimental to the Company and its shareholders for such Form F-3 Registration to be effected at such time, in which event the Company shall have the right to defer the filing of the Form F-3 Registration
Statement no more than once during any twelve (12) month period for a period of not more than ninety (90) days after receipt of the request of the Investor requesting Registration under this Section 2.2, provided that the Company
shall not register any of its other securities during such ninety (90) day period; 

  
 4 

	 	(4)	in any particular jurisdiction in which the Company would be required to qualify to do business or to execute a general consent to service of process in effecting such Registration, qualification or compliance unless
the Company is already qualified to do business or subject to service of process in that jurisdiction and except as may be required by the Securities Act; or 

  

	 	(5)	if the Company has, within the twelve (12)-month period preceding the date of such request, already effected two (2) Registrations on Form F-3 for any Investors pursuant to this Section 2.2 excluding any
Registrations from which Registrable Securities have been excluded despite an Investor’s request that they be included. 

  

	 	(c)	Underwriter’s Discretion. If the managing underwriter(s) determine(s) in good faith that marketing factors require a limitation of the number of Ordinary Shares to be underwritten, then the managing
underwriter(s) may exclude any or all Ordinary Shares held by the Investors from the Registration and the underwriting. If an Investor disapproves of the terms of any such underwriting, such Investor may elect to withdraw therefrom by written notice
to the Company and the underwriter(s), delivered at least ten (10) Business Days prior to the effective date of the Registration Statement. Any Registrable Securities excluded or withdrawn from such underwriting shall be excluded and withdrawn
from the Registration. 

  

	 	(d)	No Limit on Number of Form F-3 Registrations. There shall be no limit on the number of times the Investors may request Registration of Registrable Securities under this Section 2.2. 

2.3 Expenses. All expenses that are applicable to the sale of Registrable Securities pursuant to this Agreement and incurred in
connection with Registrations, filings or qualifications pursuant to this Agreement, including all Registration, filing and qualification fees, printers’ and accounting fees, fees and disbursements of counsel for the Company, and one counsel
for all holders of registration rights relating to any securities of the Company (up to a maximum of US$100,000), shall be borne by the Company; provided that (i) each Investor and Holder shall bear its own underwriting discounts and
commissions applicable to the sale of its Registrable Securities in such Registration and (ii) if one or more Investors or Holders engages its or their own counsel, such Investors or Holders shall bear the legal fees for any other counsel
engaged in connection with such Registration. The Company shall not, however, be required to pay for any expenses of any Registration proceeding begun pursuant to this Agreement if the Registration request is subsequently withdrawn at the request of
a majority-in-interest of the holders requesting such Registration (in which case all participating holders shall bear such expenses pro rata based upon the number of Registrable Securities that were to be thereby Registered in the withdrawn
Registration). 

  
 5 

 2.4 Obligations of the Company. Whenever required to effect the Registration of any
Registrable Securities under this Agreement the Company shall, as expeditiously as reasonably possible: 
  

	 	(a)	Registration Statement. Prepare and file with the SEC a Registration Statement with respect to such Registrable Securities and use its best efforts to cause such Registration Statement to become effective
provided, however, that (x) before filing a Registration Statement or prospectus or any amendments or supplements thereto, the Company shall provide counsel for holders of registration rights relating to securities of the Company with an
adequate and appropriate opportunity to review and comment on such Registration Statement and each prospectus included therein (and each amendment or supplement thereto) to be filled with the SEC, subject to such documents being under the
Company’s control, and (y) the Company shall notify the counsel and each seller of Registrable Securities of any stop order issued or threatened by the SEC and take all action required to prevent the entry of such stop order or to remove
it if entered. 

  

	 	(b)	Amendments and Supplements. Prepare and file with the SEC such amendments and supplements to such Registration Statement and the prospectus used in connection with such Registration Statement to keep such
Registration Statement effective for up to the shorter of one hundred twenty (120) days or until the distribution contemplated in the Registration Statement has been completed, provided that if an Investor has requested that a Registration on
Form F-3 be for an offering on a continuous basis pursuant to Rule 415 under the Securities Act, then the Company shall keep such Registration Statement effective until the shorter of (i) one hundred and eighty (180) days or
(ii) until such time as all Registrable Securities covered by such Registration Statement have been sold, and the Company shall comply with the provisions of the Securities Act with respect to the disposition of all securities covered by such
Registration Statement during such period in accordance with the intended methods of disposition by the sellers thereof set forth in such Registration Statement. 

  

	 	(c)	Prospectuses. Furnish to each Holder such numbers of copies of a prospectus, including a preliminary prospectus, in conformity with the requirements of the Securities Act, and such other documents as it may
reasonably request in order to facilitate the disposition of Registrable Securities owned by it. 

  
 6 

	 	(d)	Blue Sky. Use its best efforts to register and qualify the securities covered by such Registration Statement under such other securities or “blue sky” laws of such jurisdictions as shall be reasonably
requested by a Holder, provided that the Company shall not be required in connection therewith or as a condition thereto to qualify to do business or to file a general consent to service of process in any such states or jurisdictions unless the
Company is already subject to service of process in such jurisdiction and except as may be required by the Securities Act. 

  

	 	(e)	Underwriting. In the event of any underwritten public offering, enter into and perform its obligations under an underwriting agreement, in usual and customary form, with the managing underwriter of such offering.
The Holders participating in such underwriting shall also enter into and perform its obligations under such an agreement with respect to its securities included in such underwriting; provided that (i) no Holder will be required to make any
representations or warranties to or agreements with the Company or the underwriters other than representations, warranties or agreements specifically regarding such Holder, its rights, title and interest in the Registrable Securities and its
intended method of distribution and (ii) no Holder will be required to provide an indemnity in such underwriting agreement that is broader than the provisions in Section 2.6(b) of this Agreement. 

 

	 	(f)	Notification. Notify the Holders of Registrable Securities covered by such Registration Statement at any time when a prospectus relating thereto is required to be delivered under the Securities Act of 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 statement therein not misleading in the light of the circumstances then existing and the Company shall promptly prepare a supplement or amendment to such prospectus (and, if necessary, a post-effective amendment to the Registration
Statement) and furnish to the seller of Registrable Securities a reasonable number of copies of such supplement to or an amendment of such prospectus as may be necessary so that, after delivery to the purchasers of such Registrable Securities, such
prospectus shall 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, in light of the circumstances under which they were made, not
misleading. 

  

	 	(g)	Exchange Listing. Cause all such Registrable Securities registered pursuant hereunder to be listed on each securities exchange on which similar securities issued by the Company are then listed. 

 

	 	(h)	Transfer Agent and CUSIP. Provide a transfer agent and registrar for all Registrable Securities registered pursuant hereunder and a CUSIP number for all such Registrable Securities, in each case not later than
the effective date of such Registration. 

  
 7 

	 	(i)	SEC Compliance; Earnings Statements. Comply with all applicable rules and regulations of the SEC, and make available to its security holders, as soon as reasonably practicable but no later than fifteen
(15) months after the effective date of the Registration Statement, an earnings statement covering a period of twelve (12) months beginning after the effective date of the Registration Statement, in a manner which satisfies the provisions
of Section 11(a) of the Securities Act and Rule 158 thereunder. 

  

	 	(j)	To use its commercially reasonable efforts to furnish, at the request of the Holder requesting registration of Registrable Securities pursuant to this Agreement, on the date that such Registrable Securities, are
delivered to the underwriters for sale in connection with a registration pursuant to this Agreement, if such securities are being sold through underwriters, or, if such securities are not being sold through underwriters, on the date that the
registration statement with respect to such securities becomes effective, a copy of (i) an opinion, dated such date, of the counsel representing the Company for the purposes of such registration, in form and substance as is customarily given to
underwriters in an underwritten public offering, addressed to the underwriters, if any and (ii) a letter dated such date, from the independent certified public accountants of the Company, in form and substance as is customarily given by
independent certified public accountants to underwriters in an underwritten public offering, addressed to the underwriters. 

  

	 	(k)	Make available at reasonable times for inspection by any managing underwriter participating in any disposition of such Registrable Securities pursuant to a registration statement, the counsel selected by any managing
underwriter (each, an “Inspector” and collectively, the “Inspectors”), all financial and other records, pertinent corporate documents and properties of the Company and its subsidiaries (collectively, the
“Records”) as shall be reasonably necessary to enable them to exercise their due diligence responsibility, and cause the Company’s and its subsidiaries’ officers, directors and employees, and the independent public
accountants of the Company, to supply at reasonable times all information reasonably requested by any such Inspector in connection with such registration statement. No Records shall be disclosed by the Inspectors (and the Inspectors shall confirm
their agreement in writing in advance to the Company if the Company shall so request) unless (x) the disclosure of such Records is necessary, in the Company’s judgment, to avoid or correct a misstatement or omission in the registration
statement, (y) the release of such Records is ordered pursuant to a subpoena or other order from a court of competent jurisdiction after exhaustion of all appeals therefrom or (z) the information in such Records was known to the Inspectors
on a non-confidential basis prior to its disclosure by the Company or has been made generally available to the public. The Seller of Registrable Securities agrees that it shall, upon learning that disclosure of such Records is sought in a court of
competent jurisdiction, give notice to the Company and allow the Company, at the Company’s expense, to undertake appropriate action to prevent disclosure of the Records deemed confidential. 

  
 8 

 2.5 Furnish Information. It shall be a condition precedent to the obligations of the
Company to take any action pursuant to this Section 2 that the Investors shall furnish to the Company such information regarding themselves, the Registrable Securities held by them and the intended method of disposition of such securities as
shall be required to timely effect the Registration of its Registrable Securities. 
 2.6 Indemnification. In the event any
Registrable Securities are included in a Registration Statement under this Section 2: 
  

	 	(a)	Indemnification by the Company. To the extent permitted by law, the Company shall indemnify and hold harmless each Investor, each Holder, and each of their respective partners, officers, directors, employees,
advisors, agents, any underwriter (as defined in the Securities Act) for such Investor or Holder, and each Person, if any, who controls such Investor, Holder or underwriter within the meaning of the Securities Act or the Exchange Act, against all
losses, claims, damages and liabilities (joint or several; or actions, proceedings or settlements in respect thereof) to which such Investor, Holder, partner, officer, director, employee, advisor, agent, underwriter or controlling Person may become
subject under laws which are applicable to the Company and relate to action or inaction required of the Company in connection with any Registration, qualification or compliance, insofar as such losses, claims, damages or liabilities (or actions,
proceedings or settlements in respect thereof) arise out of or are based upon any of the following statements, omissions or violations (collectively a “Violation”): 

 

	 	(1)	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; 

  

	 	(2)	the omission or alleged omission to state therein a material fact required to be stated therein, or necessary to make the statements therein, in light of the circumstances in which they are made, not misleading; or

  

	 	(3)	any violation or alleged violation by the Company of the Applicable Securities Law, or any rule or regulation promulgated under the Applicable Securities Law; 

and the Company shall reimburse such Investor, Holder, partner, officer, director, employee, advisor, agent, underwriter and controlling
Person for any legal or other expenses reasonably incurred by them, as such expenses are incurred, in connection with investigating or defending any such loss, claim, damage, liability, action or proceeding; provided, however, that the
indemnity agreement contained in this Section 2.6(a) shall not apply to amounts paid in settlement of any such loss, claim, damage, liability, action or proceeding 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, action or proceeding to the extent that it arises out of or is based upon (A) a Violation which occurs in
reliance upon and in conformity with written information furnished expressly for use in connection with such Registration by an Investor, a Holder or any of their respective partners, officers, directors, employees, advisors, agents, underwriters or
controlling Persons or (B) delivery of a prospectus by a Holder who has received notice from the Company that the Registration Statement relating thereto contains an untrue statement of a material fact or an omission of a material fact. 

  
 9 

	 	(b)	Indemnification by the Investors. To the extent permitted by law, each Investor and Holder shall, if Registrable Securities held by such Investor or Holder are included in the securities as to which such
Registration, qualifications or compliance is being effected, indemnify and hold harmless the Company, each of its employees, advisors, agents and directors, each of its officers who has signed the Registration Statement, each Person, if any, who
controls the Company within the meaning of the Securities Act and any underwriter, against any losses, claims, damages or liabilities (joint or several; or actions, proceedings or settlements in respect thereof) to which the Company or any such
director, officer, legal counsel, controlling Person underwriter may become subject under the Securities Act, the Exchange Act or other United States federal or state law, insofar as such losses, claims, damages or liabilities (or actions,
proceedings or settlements in respect thereof) arise out of or are based upon any of the following statements, omissions or Violation, in each case to the extent (and only to the extent) that such statement, omission or Violation occurs in sole
reliance upon and in conformity with written information furnished by such Investor, such Holder, or their respective partners, officers, directors, employees, advisors, agents, underwriters or controlling Persons expressly for use in connection
with such Registration: 

  

	 	(1)	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; or 

  

	 	(2)	omission or alleged omission to state therein a material fact required to be stated therein, or necessary to make the statements therein, in light of the circumstances in which they are made, not misleading,

 and such Investor or Holder shall reimburse any legal or other expenses reasonably incurred by the Company or any such
employee, advisor, agent, director, officer, controlling Person or underwriter in connection with investigating or defending any such loss, claim, damage, liability, action or proceeding; provided, however, that the indemnity agreement contained in
this Section 2.6(b) shall not apply to amounts paid in settlement of any such loss, claim, damage, liability, action or proceeding if such settlement is effected without the consent of such Investor or Holder, which consent shall not be
unreasonably withheld; and provided, further, that except for liability for willful fraud or misrepresentation, in no event shall any indemnity under this Section 2.6(b) exceed the net proceeds received by such Investor or Holder in such
Registration. For the avoidance of doubt, the obligations of the Purchasers under this Section 2.6(b) are several but not joint. 

  
 10 

	 	(c)	Notice. Promptly after receipt by an indemnified party of notice of the commencement of any action (including any governmental action), such indemnified party shall, if a claim in respect thereof is to be made
against any indemnifying party, deliver to the indemnifying party a written notice of the commencement thereof and the indemnifying party shall have the right to participate in, and, to the extent the indemnifying party so desires, jointly with any
other indemnifying party similarly noticed, to assume the defense thereof with counsel mutually satisfactory to the parties; provided, however, that an indemnified party shall have the right to retain its own counsel, with the fees and
expenses to be paid by the indemnifying party, as incurred, if representation of such indemnified party by the counsel retained by the indemnifying party would be inappropriate due to actual or potential conflict of interests between such
indemnified party and any other party represented by such counsel in such proceeding. 

  

	 	(d)	Survival; Consents to Judgments and Settlements. The obligations of the Company and Holders under this Section 2.6 shall survive the completion of any offering of Registrable Securities in a
Registration Statement under this Section 2. No indemnifying party, in the defense of any such claim or litigation, shall, except with the consent of each indemnified party, consent to entry of any judgment or enter into any settlement which
does not include as an unconditional term thereof the giving by the claimant or plaintiff to such indemnified party of are lease from all liability in respect to such claim or litigation. 

2.7 Rule 144 Reporting. With a view to making available to the Investors the benefits of certain rules and regulations of the SEC which
may at any time permit the sale of the Registrable Securities to the public without Registration or pursuant to a Registration on Form F-3, after such time as a public market exists for the Ordinary Shares, the Company agrees to: 

 

	 	(a)	Make and keep public information available, as those terms are understood and defined in Rule 144 under the Securities Act, at all times after the effective date of the first Registration under the Securities Act filed
by the Company for an offering of its securities to the general public; 

  
 11 

	 	(b)	File with the SEC in a timely manner all reports and other documents required of the Company under the Securities Act and the Exchange Act (at any time after it has become subject to such reporting requirements); and

  

	 	(c)	So long as an Investor owns any Registrable Securities, (x) to furnish to such Investor forthwith upon request (i) a written statement by the Company as to its compliance with the reporting requirements of
Rule 144 (at any time after ninety (90) days after the effective date of the Company’s initial public offering), the Securities Act and the Exchange Act (at any time after it has become subject to such reporting requirements), or its
qualification as a registrant whose securities may be resold pursuant to Form F-3 (at any time after it so qualifies), (ii) a copy of the most recent annual or quarterly report of the Company and (iii) such other reports and documents of
the Company as such Investor may reasonably request in availing itself of any rule or regulation of the SEC that permits the selling of any such securities without Registration or pursuant to Form F-3; and (y) to procure the removal of the
legend on the restricted securities of the Company held by such Investor in connection with the resale by such Investor of such securities under Rule 144. 

2.8 Termination. The Company shall have no obligations to register any Registrable Securities proposed to be sold by any Investor or
Holder after the earlier of (a) seven (7) years following the closing of the IPO and (b) such time as pursuant to Rule 144 or another similar exemption under the Securities Act such Investor or Holder is able to sell all of its
Registrable Securities without Registration. In connection with the foregoing, if any Registrable Securities become eligible for sale pursuant to Rule 144(d) or no longer constitute “restricted securities” (as defined under Rule 144(a)),
the Company shall, upon the request of an Investor or Holder, promptly remove (or authorize the transfer agent to remove) the restrictive legend set forth in Section 1.2(c) of the Subscription Agreement from the certificates for such share
securities.
