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

“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 4, 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 Purchaser wishes to invest in the Company by acquiring Ordinary Shares in the Company in a private transaction with the Company
exempt from registration pursuant to Regulation S of the U.S. Securities Act of 1933, as amended (“Regulation S” and the “Securities Act,” respectively); 

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,
at the Closing (as defined below), the Purchaser hereby agrees to purchase, and the Company hereby agrees to issue, sell and deliver to the Purchaser, subject to and concurrent with the Offering, at a price per Ordinary Share equal to the Offer
Price (as defined below), that certain number (as such number is determined pursuant to Section 1.2 below) of Ordinary Shares (the “Purchased Shares”), 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
connection with the Offering (the “Final Prospectus”) divided by the number of Ordinary Shares represented by one ADS. All such sales shall be made (i) on the same terms as the ADSs being offered in the Offering and
(ii) pursuant to and in reliance upon Regulation S. 

 Section 1.2 Closing. 

(a) Closing. Subject to Section 1.3, the closing (the “Closing”) of the sale and purchase of the Ordinary 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 the Purchaser may mutually agree. The total number of the
Ordinary Shares that the Purchaser shall purchase at the Closing shall be equal to the aggregate purchase price of US$15 million (the “Purchase Price”) divided by the Offer Price; provided, however, that (i) no
fractional shares of Ordinary Shares will be issued, (ii) any fractions shall be rounded down to the nearest whole number of Ordinary Shares, and (iii) the 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 Closing are referred to herein as the “Closing Date.” 

(b) Payment and Delivery. At the Closing, the Purchaser shall pay and deliver the total consideration to the Company in
U.S. dollars by wire transfer, or by such other method mutually agreeable to the parties, of immediately available funds to such bank account designated in writing by the Company, and the Company shall deliver one or more duly executed share
certificates in original form, registered in the name of the Purchaser, together with a certified true copy of the register of members of the Company, evidencing the Ordinary Shares being issued and sold to the Purchaser. 

(c) Restrictive Legend. Each certificate representing the Purchased Shares shall be endorsed with the following legend:

DURING THE 40 DAYS FOLLOWING CLOSING OF THE PURCHASE. ANY ATTEMPT TO TRANSFER, SELL, PLEDGE OR HYPOTHECATE THIS SECURITY IN VIOLATION OF THESE RESTRICTIONS SHALL BE VOID. THE COMPANY SHALL NOT BE REQUIRED TO REGISTER THE TRANSFER OF THIS SECURITY TO
ANY PERSON UNLESS (X) SUCH TRANSFER IS MADE PURSUANT TO THE EXEMPTION FROM REGISTRATION UNDER THE ACT PROVIDED BY RULE 144 OR RULE 144A THEREUNDER, IF AVAILABLE OR (Y) THE COMPANY RECEIVES FROM THE PROPOSED TRANSFEREE A WRITTEN INSTRUMENT
IN FORM AND SUBSTANCE REASONABLY SATISFACTORY TO THE COMPANY IN WHICH SUCH TRANSFEREE MAKES THE REPRESENTATIONS AND WARRANTIES SET FORTH IN SECTION 2.2(F) OF THE SHARE PURCHASE AGREEMENT BETWEEN THE COMPANY AND PURCHASER DATED APRIL 27, 2014, AND,

any Third Party Claim by, within (30) days of receipt of the Claim Notice, notifying the Indemnified Party in writing that the Indemnifying Party elects to assume the defense of such Third Party 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

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.
