 5.
Conversion. 
 (a) Automatic Conversion. If the closing of the IPO occurs prior to the Maturity Date, then upon the

the Note shall be deemed interest free during the period between the date hereof and the date of conversion. All such Investment Securities automatically converted from the Note shall be subject to a six-month lock up period at the request of the
Underwriter. 
 (b) Conversion Procedure. If this Note is to be automatically converted, written notice shall be delivered to the
Investor notifying the Investor of the conversion to be effected, specifying the Conversion Price, the principal amount of the Note to be converted, the date on which such conversion is expected to occur and calling upon the Investor to surrender to
the Company, in the manner and at the place designated, the Note. The Investor also agrees to deliver the original of this Note (or a notice to the effect that the original Note has been lost, stolen or destroyed and other evidence reasonably
satisfactory to the Company) at the closing of the IPO for cancellation; provided, however, that upon the closing of the IPO, this Note shall be deemed converted and of no further force and effect, whether or not it is delivered for
cancellation as set forth in this sentence. The Company shall, as soon as practicable thereafter, issue and deliver to the Investor a certificate or certificates for the Conversion Shares to which the Investor shall be entitled upon such conversion,
including a check payable to the Investor for any cash amounts payable as described in Section 5(c). Any conversion of this Note pursuant to Section 5(a) shall be deemed to have been made immediately prior to the closing of the IPO and on
and after such date the Persons entitled to receive the Conversion Shares issuable upon such conversion shall be treated for all purposes as the record holder of such shares. 







 (c) Fractional Shares; Interest; Effect of Conversion. No fractional shares shall be
issued upon conversion of this Note. In lieu of the Company issuing any fractional shares to the Investor upon the conversion of this Note, the Company shall pay to the Investor an amount equal to the product obtained by multiplying the Conversion
Price by the fraction of a share not issued pursuant to the previous sentence. Upon conversion of this Note in full and the payment of the amounts specified in this paragraph, Company shall be forever released from all its obligations and
liabilities under this Note and this Note shall be deemed of no further force or effect, whether or not the original of this Note has been delivered to the Company for cancellation. 

(d) Reservation of Shares Issuable Upon Conversion. The Company shall reserve and keep available out of its authorized but unissued
Investment Securities solely for the purpose of effecting the conversion of this Note such number of the Investment Securities as shall be sufficient to effect the conversion of this Note. 

6. Definitions. As used in this Note, the following capitalized terms have the following meanings: 

“Change in Control” means (a) the sale, lease or other disposition (in one or a series of related transactions) of all
or substantially all of the Company’s assets to one Person or a group of Persons acting in concert, (b) the sale, exchange or transfer, in one or a series of related transactions, of a majority of the outstanding share capital of the
Company to one Person or a group of Persons acting in concert, under circumstances in which the holders of the share capital of the Company immediately prior to such transaction beneficially own less than a majority in voting power of the
outstanding share capital of the Company or the acquiring Person immediately following such transaction, or (c) a merger, consolidation, amalgamation, recapitalization, reclassification, reorganization or similar business combination
transaction involving the Company under circumstances in which holders of the share capital of the Company immediately prior to such transaction beneficially own less than a majority in voting power of the outstanding share capital of the Company,
or the surviving or resulting corporation or acquirer, as the case may be, immediately following such transaction. 
 “Conversion
Price” shall mean a per share price equal to 80% of the Per Share IPO Price. For the avoidance of doubt, the Company and the Investor acknowledge that if and to the extent the Conversion Shares are Class B Ordinary Shares, the Conversion
Price defined hereof is based on the assumption that one Class B Ordinary Share is convertible into one share of the Listing Equity Securities; and should the conversion ratio between the Class B Ordinary Shares and the Listing Equity Securities be
different, the Company and the Investor shall proportionately adjust the Conversion Price in good faith to achieve an equitable result. 







 “Event of Default” has the meaning given in Section 3 hereof. 

“Investor” shall mean the Person specified in the introductory paragraph of this Note or any Person who shall at the time be
the registered holder of this Note.

obligations, howsoever arising, owed by the Company to the Investor of every kind and description, now existing or hereafter arising under or pursuant to the terms of this Note and the other Transaction Documents, including, all interest, fees,
charges, expenses, attorneys’ fees and costs and accountants’ fees and costs chargeable to and payable by the Company hereunder and thereunder, in each case, whether direct or indirect, absolute or contingent, due or to become due. 

“Per Share IPO Price” shall mean means the quotient obtained by dividing (a) the final initial public offering price per
ADS in the IPO by (b) the number of Listing Equity Securities each ADS represents. 
 “Purchase Agreement” shall mean
the Note Purchase Agreement dated as of October 20, 2013 (as amended, modified or supplemented), by and between the Company and the Investor. 

“Transaction Documents” shall mean this Note and the Purchase Agreement. 

Capitalized terms used but not defined in this Note have the same meaning as set forth in the Purchase Agreement. 

7. Miscellaneous. 

(a) Successors and Assigns; Transfer of this Note or Securities Issuable on Conversion Hereof.

shall be binding upon and benefit their respective successors, assigns, heirs, administrators and transferees.

 (f) Expenses; Waivers. If action is instituted to collect this Note, the Company promises to pay all costs and expenses,
including, without limitation, reasonable attorneys’ fees and costs, incurred in connection with such action. The Company hereby waives notice of default, presentment or demand for payment, protest or notice of nonpayment or dishonor and all
other notices or demands relative to this instrument. 
 (g) Governing Law. This Agreement shall be governed by and construed in
accordance with the laws of the State of New York, without giving effect to any choice or conflict of law provision or rule (whether of the State of New York or any other jurisdiction) that would cause the application of the laws of any jurisdiction
other than the State of New York.
