Critical Accounting Policies. The section entitled “Management’s Discussion and Analysis of Financial Condition and Results of Operations” in the Time of Sale Prospectus and the Prospectus accurately and fairly describes (i) the accounting policies that the Company believes are the most important in the portrayal of the Company’s financial condition and results of operations and that require management’s most difficult subjective or complex judgment; (ii) the material judgments and uncertainties affecting the application of critical accounting policies and estimates; (iii) the likelihood that materially different amounts would be reported under different conditions or using different assumptions and an explanation thereof; (iv) all material trends, demands, commitments and events known to the Company, and uncertainties, and the potential effects thereof, that the Company believes would materially affect its liquidity and are reasonably likely to occur; and (v) all off-balance sheet commitments and arrangements of the Company and its Subsidiaries and Consolidated Affiliated Entities, if any. The Company’s directors and management have reviewed and agreed with the selection, application and disclosure of the Company’s critical accounting policies as described in the Registration Statement, the Time of Sale Prospectus and the Prospectus and have consulted with its independent accountants with regards to such disclosure.

Each of the Company’s independent directors meets the criteria for “independence” under the ▇▇▇▇▇▇▇▇-▇▇▇▇▇ Act, the rules and regulations of the Commission and the rules of NASDAQ. The Company and its Subsidiaries and the Consolidated Affiliated Entities maintain an effective system of “disclosure controls and procedures” (as defined in Rule 13a-15(e) of the Exchange Act) that complies with the requirements of the Exchange Act and that has been designed to ensure that information required to be disclosed by the Company in reports that it files or submits under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the Commission’s rules and forms, including controls and procedures designed to ensure that such information is accumulated and communicated to the Company’s management as appropriate to allow timely decisions regarding required disclosure.

All payments to be made by the Company to the Underwriters hereunder, if any, shall be made free and clear of and without withholding or deduction for or on account of any present or future taxes, duties or governmental charges whatsoever unless the Company is compelled by law to deduct or withhold such taxes, duties or charges. In that event, the Company shall pay such additional amounts as may be necessary in order that the net amounts received after such withholding or deduction shall equal the amounts that would have been received if no withholding or deduction had been made, except to the extent of taxes that would not have been imposed but for (i) the recipient’s being a resident of the jurisdiction imposing such taxes, having a permanent establishment therein, or having a similar connection with such jurisdiction (in each case, other than as a result of the transactions contemplated by this Agreement) or (ii) the recipient’s failure to comply with a request from the Company to provide any documentation or certification that the recipient is legally able to provide (and can do so without undue hardship) concerning the recipient’s nationality, residence, identity or connection with the applicable taxing jurisdiction, and that is required as a precondition to exemption from, or reduction in the rate of, the withholding or deduction of such taxes. In addition, all sums payable by the Company to an Underwriter hereunder shall be considered exclusive of any value added or similar taxes. Where the Company is obliged to pay value added or similar tax on any amount payable hereunder to an Underwriter, the Company shall, in addition to the sum payable hereunder, pay an amount equal to any applicable value added or similar tax.

The Company, without the prior written consent of the Representatives on behalf of the Underwriters, will not, during the period ending 90 days after the date of the Prospectus (the “Restricted Period”), (i) 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, lend, or otherwise transfer or dispose of, directly or indirectly, any Ordinary Shares or American Depositary Shares beneficially owned (as such term is used in Rule 13d-3 of the Exchange Act) or any other securities so owned convertible into or exercisable or exchangeable for Ordinary Shares or American Depositary Shares 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 or American Depositary Shares, whether any such transaction described in clause (i) or (ii) above is to be settled by delivery of Ordinary Shares, American Depositary Shares or such other securities, in cash or otherwise, (iii) file or submit any registration statement with the Commission relating to the offering of any Ordinary Shares, American Depositary Shares or any securities convertible into or exercisable or exchangeable for Ordinary Shares or American Depositary Shares, or (iv) publicly disclose the intention to do any of the foregoing.

The Company agrees to instruct its share registrar not to give effect to any share transfers directly or indirectly by any of the individuals or entities listed on Schedule V during the Restricted Period.

Each Selling Shareholder, severally and not jointly, covenants with each Underwriter as follows:

Each Selling Shareholder will deliver to each Underwriter (or its agent), prior to or at the Closing Date, a properly completed and executed Internal Revenue Service (“IRS”) Form W-9 or an IRS Form W-8, as appropriate, together with all required attachments to such form.

All payments to be made by each Selling Shareholder to the Underwriters hereunder shall be made free and clear of and without withholding or deduction for or on account of any present or future taxes, duties or governmental charges whatsoever unless such Selling Shareholder is compelled by law to deduct or withhold such taxes, duties or charges. In that event, such Selling Shareholder shall pay such additional amounts as may be necessary in order that the net amounts received after such withholding or deduction shall equal the amounts that would have been received if no withholding or deduction had been made, except to the extent of taxes that would not have been imposed but for (i) the recipient’s being a resident of the jurisdiction imposing such taxes, having a permanent establishment therein, or having a similar connection with such jurisdiction (in each case, other than as a result of the transactions contemplated by this Agreement) or (ii) the recipient’s failure to comply with a request from such Selling Shareholder to provide any documentation or certification that the recipient is legally able to provide (and can do so without undue hardship) concerning the recipient’s nationality, residence, identity or connection with the applicable taxing jurisdiction, and that is required as a precondition to exemption from, or reduction in the rate of, the withholding or deduction of such taxes. In addition, all sums payable by such Selling Shareholder to an Underwriter hereunder shall be considered exclusive of any value added or similar taxes. Where such Selling Shareholder is obliged to pay value added or similar tax on any amount payable hereunder to an Underwriter, such Selling Shareholder shall, in addition to the sum payable hereunder, pay an amount equal to any applicable value added or similar tax.

EXPENSES.

COVENANTS OF THE UNDERWRITERS. Each Underwriter, severally and not jointly, covenants with the Company not to take any action that would result in the Company being required to file with the Commission under Rule 433(d) a free writing prospectus prepared by or on behalf of such Underwriter that otherwise would not be required to be filed by the Company thereunder, but for the action of such Underwriter.

Each Selling Shareholder agrees, severally and not jointly, to indemnify and hold harmless each Underwriter, each director, officer, employee, each person, if any, who controls any Underwriter within the meaning of either Section 15 of the Securities Act or Section 20 of the Exchange Act and each affiliate of any Underwriter within the meaning of Rule 405 under the Securities Act from and against any and all losses, claims, damages and liabilities (including, without limitation, any legal or other expenses reasonably incurred in connection with defending or investigating any such action or claim) that arise out of, or are based upon, any untrue statement or alleged untrue statement of a material fact contained in the Registration Statement or any amendment thereof, any preliminary prospectus, the Time of Sale Prospectus or any amendment or supplement thereto, any issuer free writing prospectus as defined in Rule 433(h) under the Securities Act, any Company information that the Company has filed, or is required to file, pursuant to Rule 433(d) under the Securities Act, any road show, or the Prospectus or any amendment or supplement thereto, or arise out of, or are based upon, any omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, except insofar as such losses, claims, damages or liabilities are caused by any such untrue statement or omission or alleged untrue statement or omission made in reliance upon and in conformity with the Underwriter Information (as defined in Section 11(c) hereof); provided that notwithstanding the generality of the foregoing, the Selling Shareholders shall only be liable pursuant to this Section 11(b) to the extent that such losses, claims, damages and liabilities arise out of or are based upon an untrue statement or omission or alleged untrue statement or omission made in reliance upon and in conformity with information furnished in writing to the Company by such Selling Shareholder expressly for use in the Registration Statement, any preliminary prospectus, the Time of Sale Prospectus, any issuer free writing prospectus, road show or the Prospectus or any amendment or supplement thereto; provided further that the liability under this subsection of such Selling Shareholder shall be limited to an amount equal to the aggregate gross proceeds after underwriting commissions and discounts received by such Selling Shareholder from the sale of Offered ADSs sold by such Selling Shareholder hereunder.

Each Underwriter agrees, severally and not jointly, to indemnify and hold harmless the Company, the directors of the Company, the Selling Shareholders, the officers of the Company who sign the Registration Statement and each person, if any, who controls the Company or any Selling Shareholder within the meaning of either Section 15 of the Securities Act or Section 20 of the Exchange Act from and against any and all losses, claims, damages and liabilities (including, without limitation, any legal or other expenses reasonably incurred in connection with defending or investigating any such action or claim) caused by any untrue statement or alleged untrue statement of a material fact contained in the Registration Statement or any amendment thereof, any preliminary prospectus, the Time of Sale Prospectus or any amendment or supplement thereto, any issuer free writing prospectus as defined in Rule 433(h) under the Securities Act, any Company information that the Company has filed, or is required to file, pursuant to Rule 433(d) under the Securities Act, any road show or the Prospectus or any amendment or supplement thereto, or caused by any 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 under which they were made, not misleading, but only with reference to information relating to such Underwriter furnished to the Company in writing by such Underwriter through the Representatives expressly for use in the Registration Statement, any preliminary prospectus, the Time of Sale Prospectus or the Prospectus or any amendment or supplement thereto, it being understood and agreed that the only such information furnished by any Underwriter consists of the addresses of the Representatives appearing in the [seventh] paragraph under the caption “Underwriting” (the “Underwriter Information”).

In case any proceeding (including any governmental investigation) shall be instituted involving any person in respect of which indemnity may be sought pursuant to Section 9(a), 9(b) or 9(c), such person (the “indemnified party”) shall promptly notify the person against whom such indemnity may be sought (the “indemnifying party”) in writing and the indemnifying party, upon request of the indemnified party, shall retain counsel reasonably satisfactory to the indemnified party to represent the indemnified party and any others the indemnifying party may designate in such proceeding and shall pay the fees and disbursements of such counsel related to such proceeding. In any such proceeding, any indemnified party shall have the right to retain its own counsel, but the fees and expenses of such counsel shall be at the expense of such indemnified party unless (i) the indemnifying party and the indemnified party shall have mutually agreed to the retention of such counsel or (ii) the named parties to any such proceeding (including any impleaded parties) include both the indemnifying party and the indemnified party and representation of both parties by the same counsel would be inappropriate due to actual or potential differing interests between them. It is understood that the indemnifying party shall not, in respect of the legal expenses of any indemnified party in connection with any proceeding or related proceedings in the same jurisdiction, be liable for (i) the fees and expenses of more than one separate firm (in addition to any local counsel) for all Underwriters and all persons, if any, who control any Underwriter within the meaning of either Section 15 of the Securities Act or Section 20 of the Exchange Act or who are affiliates of any Underwriter within the meaning of Rule 405 under the Securities Act, (ii) the fees and expenses of more than one separate firm (in addition to any local counsel) for the Company, its directors, its officers who sign the Registration Statement and each person, if any, who controls the Company within the meaning of either such Section and (iii) the fees and expenses of more than one separate firm (in addition to any local counsel) for all Selling Shareholders and all persons, if any, who control any Selling Shareholder within the meaning of either such Section, and that all such fees and expenses shall be reimbursed as they are incurred. In the case of any such separate firm for the Underwriters and such directors, officers, employees, control persons and affiliates of any Underwriters, such firm shall be designated in writing by the Representatives. In the case of any such separate firm for the Company, and such directors, officers and control persons of the Company, such firm shall be designated in writing by the Company. In the case of any such separate firm for the Selling Shareholders and such control persons of any Selling Shareholders, such firm shall be designated in writing by the Selling Shareholders. The indemnifying party shall not be liable for any settlement of any proceeding effected without its written consent, but if settled with such consent or if there be a final judgment for the plaintiff, the indemnifying party agrees to indemnify the indemnified party from and against any loss or liability by reason of such settlement or judgment. Notwithstanding the foregoing sentence, if at any time an indemnified party shall have requested an indemnifying party to reimburse the indemnified party for fees and expenses of counsel as contemplated by the second and third sentences of this paragraph, the indemnifying party agrees that it shall be liable for any settlement of any proceeding effected without its written consent if (i) such settlement is entered into more than 30 days after receipt by such indemnifying party of the aforesaid request and (ii) such indemnifying party shall not have reimbursed the indemnified party in accordance with such request prior to the date of such settlement. No indemnifying party shall, without the prior written consent of the indemnified party, effect any settlement of any pending or threatened proceeding in respect of which any indemnified party is or could have been a party and indemnity could have been sought hereunder by such indemnified party, unless such settlement (x) includes an unconditional release of such indemnified party from all liability on claims that are the subject matter of such proceeding, and (y) does not include any statement as to, or any admission of, fault, culpability or a failure to act by or on behalf of any indemnified party.

To the extent the indemnification provided for in Section 9(a), 9(b) or 9(c), is unavailable to an indemnified party or insufficient in respect of any losses, claims, damages or liabilities referred to therein, then each indemnifying party under such paragraph, in lieu of indemnifying such indemnified party thereunder, shall contribute to the amount paid or payable by such indemnified party as a result of such losses, claims, damages or liabilities (i) in such proportion as is appropriate to reflect the relative benefits received by the indemnifying party or parties on the one hand and the indemnified party or parties on the other hand from the offering of the Offered Securities or (ii) if the allocation provided by clause 9(e)(i) above is not permitted by applicable law, in such proportion as is appropriate to reflect not only the relative benefits referred to in clause 9(e)(i) above but also the relative fault of the indemnifying party or parties on the one hand and of the indemnified party or parties on the other hand in connection with the statements or omissions that resulted in such losses, claims, damages or liabilities, as well as any other relevant equitable considerations. The relative benefits received by the Company and the Selling Shareholders on the one hand and the Underwriters on the other hand in connection with the offering of the Offered Securities shall be deemed to be in the same respective proportions as the net proceeds from the offering of the Offered Securities (before deducting expenses) received by each of the Company and the Selling Shareholders and the total underwriting discounts and commissions received by the Underwriters, in each case as set forth in the table on the cover of the Prospectus, bear to the aggregate Public Offering Price of the Offered Securities. The relative fault of the Company and the Selling Shareholders on the one hand and the Underwriters on the other hand 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 Company, the Selling Shareholders or by the Underwriters and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission. The Underwriters’ respective obligations to contribute pursuant to this Section 9 are several in proportion to the respective number of Offered ADSs they have purchased hereunder, and not joint.

The Company, the Selling Shareholders and the Underwriters agree that it would not be just or equitable if contribution pursuant to this Section 9 were determined by pro rata allocation (even if the Underwriters were treated as one entity for such purpose) or by any other method of allocation that does not take account of the equitable considerations referred to in Section 9(e). The amount paid or payable by an indemnified party as a result of the losses, claims, damages and liabilities referred to in Section 9(e) shall be deemed to include, subject to the limitations set forth above, any legal or other expenses reasonably incurred by such indemnified party in connection with investigating or defending any such action or claim. Notwithstanding the provisions of this Section 9, in no event shall an Underwriter be required to contribute any amount in excess of the amount by which the total underwriting discounts and commissions received by such Underwriter with respect to the offering of the Offered Securities exceeds the amount of any damages that such Underwriter has otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission. No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. The remedies provided for in this Section 9 are not exclusive and shall not limit any rights or remedies which may otherwise be available to any indemnified party at law or in equity.

The indemnity and contribution provisions contained in this Section 9 and the representations, warranties and other statements of the Company and the Selling Shareholders contained in this Agreement shall remain operative and in full force and effect regardless of (i) any termination of this Agreement, (ii) any investigation made by or on behalf of any Underwriter, its directors, officers or employees, any person controlling any Underwriter or any affiliate of any Underwriter, any Selling Shareholder, its officers or directors, any person controlling any Selling Shareholder, or the Company, its officers or directors or any person controlling the Company and (iii) acceptance of and payment for any of the Offered Securities.

TERMINATION. The Underwriters may terminate this Agreement by notice given by the Representatives to the Company and the Selling Shareholders, if after the execution and delivery of this Agreement and prior to the Closing Date (i) trading generally shall have been suspended or materially limited on, or by, as the case may be, any of the New York Stock Exchange, the NYSE MKT, NASDAQ, the Hong Kong Stock Exchange or other relevant exchanges, (ii) trading of any securities of the Company shall have been suspended on any exchange or in any over-the-counter market, (iii) a material disruption in securities settlement, payment or clearance services in the United States, the PRC, the Cayman Islands, Hong Kong or Singapore shall have occurred, (iv) any moratorium on commercial banking activities shall have been declared by United States Federal, ▇▇▇ ▇▇▇▇ ▇▇▇▇▇, ▇▇▇, ▇▇▇▇▇▇ ▇▇▇▇▇▇▇, ▇▇▇▇ ▇▇▇▇ or Singapore authorities or with respect to Clearstream or Euroclear systems in Europe, or (v) there shall have occurred any outbreak or escalation of hostilities, or any change in financial markets, currency exchange rates or controls or any calamity or crisis that, in the judgment of the Representatives, is material and adverse and which, singly or together with any other event specified in this clause (v), makes it, in the judgment of the Representatives, impracticable or inadvisable to proceed with the offer, sale or delivery of the Offered Securities on the terms and in the manner contemplated in the Time of Sale Prospectus or the Prospectus or to enforce contracts for the sale of the ADSs.

EFFECTIVENESS; DEFAULTING UNDERWRITERS. This Agreement shall become effective upon the execution and delivery hereof by the parties hereto.

SUBMISSION TO JURISDICTION; APPOINTMENT OF AGENT FOR SERVICE.

The Company, each of the Company’s Subsidiaries and Consolidated Affiliated Entities, the Selling Shareholders and each of the Selling Shareholder’s subsidiaries irrevocably and unconditionally waive any objection to the laying of venue of any suit or proceeding arising out of or relating to this Agreement, the Deposit Agreement, the Time of Sale Prospectus, the Prospectus, the Registration Statement, the ADS Registration Statement, the offering of the Offered Securities, or any transactions contemplated hereby in the New York Courts, and irrevocably and unconditionally waives and agrees not to plead or claim in any such court that any such suit or proceeding in any such court has been brought in an inconvenient forum. The Company and the Selling Shareholders (other than Owap Investment Pte Ltd) irrevocably appoint [Cogency Global Inc.] as its respective authorized agent in the Borough of Manhattan in The City of New York upon which process may be served in any such suit or proceeding, and agree that service of process in any manner permitted by applicable law upon such agent shall be deemed in every respect effective service of process in any manner permitted by applicable law upon the Company and the Selling Shareholders (other than Owap Investment Pte Ltd), as the case may be, in any such suit or proceeding. The Company and the Selling Shareholders (other than Owap Investment Pte Ltd) further agree to take any and all action as may be necessary to maintain such designation and appointment of such agent in full force and effect for a period of seven years from the date of this Agreement. Owap Investment Pte Ltd irrevocably appoints GIC (New York) Inc. as its respective authorized agent in the Borough of Manhattan in The City of New York upon which process may be served in any such suit or proceeding, and agrees that service of process in any manner permitted by applicable law upon such agent shall be deemed in every respect effective service of process in any manner permitted by applicable law upon Owap Investment Pte Ltd, in any such suit or proceeding. Owap Investment Pte Ltd further agrees to take any and all action as may be necessary to maintain such designation and appointment of such agent in full force and effect for a period of seven years from the date of this Agreement.

JUDGMENT CURRENCY. If for the purposes of obtaining judgment in any court it is necessary to convert a sum due hereunder into any currency other than United States dollars, the parties hereto agree, to the fullest extent permitted by law, that the rate of exchange used shall be the rate at which in accordance with normal banking procedures the Underwriters could purchase United States dollars with such other currency in The City of New York on the business day preceding that on which final judgment is given. The obligation of the Company or any Selling Shareholder pursuant to this Agreement with respect to any sum due from it to any Underwriter or any person controlling any Underwriter shall, notwithstanding any judgment in a currency other than United States dollars, not be discharged until the first business day following receipt by such Underwriter or controlling person of any sum in such other currency, and only to the extent that such Underwriter or controlling person may in accordance with normal banking procedures purchase United States dollars with such other currency. If the United States dollars so purchased are less than the sum originally due to such Underwriter or controlling person hereunder, the Company and each Selling Shareholder agrees as a separate obligation and notwithstanding any such judgment, to indemnify such Underwriter or controlling person against such loss. If the United States dollars so purchased are greater than the sum originally due to such Underwriter or controlling person hereunder, such Underwriter or controlling person agrees to pay to the Company or the relevant Selling Shareholder(s), as applicable, an amount equal to the excess of the dollars so purchased over the sum originally due to such underwriter or controlling person hereunder.

This Agreement, together with any contemporaneous written agreements and any prior written agreements (to the extent not superseded by this Agreement) that relate to the sale and purchase of the Offered Securities and the offering of the Offered Securities, represents the entire agreement between the Company and the Selling Shareholders, on the one hand, and the Underwriters, on the other, with respect to the preparation of any preliminary prospectus, the Time of Sale Prospectus, the Prospectus, the conduct of the offering, and the purchase and sale of the Offered Securities and the offering of the Offered Securities.
