Ladies and Gentlemen:

NetQin Mobile Inc., an exempted company incorporated with limited liability under the laws of the Cayman Islands (the “Company”), proposes to issue and sell to the several Underwriters listed in Schedule 1 hereto (the “Underwriters”), for whom you are acting as representative (the “Representative”), an aggregate of 7,142,858 American depositary shares (each, an “ADS,” and collectively, the “Underwritten ADSs”), representing 35,714,290 Class A common shares, par value US$0.0001 per share, of the Company (the “Common Shares”). In addition, the Company proposes to issue and sell, at the option of the Underwriters, up to an additional 1,071,428 ADSs, representing 5,357,140 additional Shares, (the “Option ADSs”). The ADSs and the Option ADSs are herein referred to as the “Offered ADSs”. The Common Shares represented by the ADSs are herein referred to as the “Underwritten Shares,” the Common Shares represented by the Option ADSs are herein referred to as the “Option Shares” and the Underwritten Shares and the Option Shares are herein referred to as the “Shares.”

The Company hereby acknowledges that, as part of the proposed offering of the Offered ADSs, it has requested Xxxxx Xxxxxxx & Co., and Xxxxx Xxxxxxx & Co. has agreed, to administer a directed share program (the “Directed Share Program”) under which up to 571,429 ADSs, or approximately 8% of the ADSs to be purchased by the Underwriters (the “Reserved ADSs”), shall be reserved for purchase at the initial public offering price by the Company’s directors, officers, employees, consultants, associates and other persons having a relationship with the Company as designated by the Company (the “Directed Share Participants”) as part of the distribution of the Offered ADSs by the Underwriters, subject to the terms of this Underwriting Agreement, the applicable rules, regulations and interpretations of the Financial Industry Regulatory Authority (“FINRA”) and all other applicable laws, rules and regulations. The number of ADSs available

for sale to the general public will be reduced to the extent that Directed Share Participants purchase Reserved ADSs. The Underwriters may offer any Reserved ADSs not purchased by Directed Share Participants to the general public on the same basis as the other Offered ADSs being sold hereunder. The Company has supplied Xxxxx Xxxxxxx & Co. with the names, addresses and telephone numbers of the individuals or other entities which the Company has designated to be participants in the Directed Share Program. It is understood that any number of those so designated to participate in the Directed Share Program may decline to do so.

The Offered ADSs are to be issued pursuant to a deposit agreement (the “Deposit Agreement”), to be dated as of the Closing Date (defined below), or a date prior to the Closing Date, among the Company, Deutsche Bank Trust Company Americas, as depositary (the “Depositary”), and owners and beneficial owners from time to time of the ADSs. Each Offered ADS will initially represent the right to receive five Class A Common Shares deposited pursuant to the Deposit Agreement.

The Company hereby confirms their agreement with the several Underwriters concerning the purchase and sale of the Offered ADSs, as follows:

1. Registration Statement. The Company has prepared and filed with the Securities and Exchange Commission (the “Commission”) under the Securities Act of 1933, as amended, and the rules and regulations of the Commission thereunder (collectively, the “Securities Act”), a registration statement on Form F-1 (File No. 333-172839), including a prospectus, relating to the Shares. Such registration statement, as amended at the time it became effective, including the information, if any, deemed pursuant to Rule 430A or 430C under the Securities Act to be part of the registration statement at the time of its effectiveness (“Rule 430 Information”), is referred to herein as the “Registration Statement”; and as used herein, the term “Preliminary Prospectus” means each prospectus included in such registration statement (and any amendments thereto) before effectiveness, any prospectus filed with the Commission pursuant to Rule 424(a) under the Securities Act and the prospectus included in the Registration Statement at the time of its effectiveness that omits Rule 430 Information, and the term “Prospectus” means the prospectus in the form first used (or made available upon request of purchasers pursuant to Rule 173 under the Securities Act) with the public offering price, other Rule 430 information and other final terms of the Shares offered and otherwise satisfies Section 10(a) of the Act. If the Company has filed an abbreviated registration statement pursuant to Rule 462(b) under the Securities Act (the “Rule 462 Registration Statement”), then any reference herein to the term “Registration Statement” shall be deemed to include such Rule 462 Registration Statement. Capitalized terms used but not defined herein shall have the meanings given to such terms in the Registration Statement and the Prospectus.

At or prior to the Applicable Time (as defined below), the Company had prepared the following information (collectively with the pricing information set forth on Annex B, the “Pricing Disclosure Package”): a Preliminary Prospectus dated April 15, 2011 (“Statutory Prospectus”) and each “free-writing prospectus” (as defined pursuant to Rule 405 under the Securities Act) listed on Annex B hereto.

In addition, the Company agrees to issue and sell the Option ADSs to the several Underwriters as provided in this Agreement, and the Underwriters, on the basis of the representations, warranties and agreements set forth herein and subject to the conditions set forth herein, shall have the option to purchase, severally and not jointly, from the Company the Option ADSs at the Purchase Price less an amount per ADS equal to any dividends or distributions declared by the Company and payable on the Underwritten ADSs but not payable on the Option ADSs. If any Option ADSs are to be purchased, the number of Option ADSs to be purchased by each Underwriter shall be the number of Option ADSs which bears the same ratio to the aggregate number of Option ADSs being purchased as the number of Underwritten ADSs set forth opposite the name of such Underwriter in Schedule 1 hereto (or such number increased as set forth in Section 11 hereof) bears to the aggregate number of Underwritten ADSs being purchased from the Company by the several Underwriters, subject, however, to such adjustments to eliminate any fractional ADSs as the Representative in their sole discretion shall make. Any such election to purchase Option ADSs shall be made in proportion to the maximum number of Option ADSs to be sold by the Company as set forth in Schedule 2 hereto.

The Underwriters may exercise the option to purchase Option ADSs at any time in whole, or from time to time in part, on or before the thirtieth day following the date of the Prospectus, by written notice from the Representative to the Company. Such notice shall set forth the aggregate number of Option ADSs as to which the option is being exercised and the date and time when the Option ADSs are to be delivered and the Option ADSs paid for, which may be the same date and time as the Closing Date (as hereinafter defined) but shall not be earlier than the Closing Date or later than the tenth full business day (as hereinafter defined) after the date of such notice (unless such time and date are postponed in accordance with the provisions of Section 11 hereof). Any such notice shall be given at least two business days prior to the date and time of delivery specified therein.

(b) The Company understands that the Underwriters intend to make a public offering of the Offered ADSs as soon after the effectiveness of the Registration Statement and this Agreement as in the judgment of the Representative is advisable, and initially to offer the Offered ADSs on the terms set forth in the Prospectus.

(d) The Company acknowledges and agrees that the Underwriters are acting solely in the capacity of an arm’s length contractual counterparty to the Company with respect to the offering of the Offered ADSs contemplated hereby (including in connection with determining the terms of the offering) and not as a financial advisor or a fiduciary to, or an agent of, the Company or any other person.

(d) Notice and Procedures. If any suit, action, proceeding (including any governmental or regulatory investigation), claim or demand shall be brought or asserted against any person in respect of which indemnification may be sought pursuant to the preceding paragraphs of this Section 8, such person (the “Indemnified Person”) shall promptly notify the person against whom such indemnification may be sought (the “Indemnifying Person”) in writing; provided that the failure to notify the Indemnifying Person shall not relieve it from any liability that it may have under the preceding paragraphs of this Section 8 except to the extent that it has been materially prejudiced (through the forfeiture of substantive rights or defenses) by such failure; and provided further that the failure to notify the Indemnifying Person shall not relieve it from any liability that it may have to an Indemnified Person otherwise than under the preceding paragraphs of this Section 8. If any such proceeding shall be brought or asserted against an Indemnified Person and it shall have notified the Indemnifying Person thereof, the Indemnifying Person shall retain counsel reasonably satisfactory to the Indemnified Person (who shall not, without the consent of the Indemnified Person, be counsel to the Indemnifying Person) to represent the Indemnified Person in such proceeding and shall pay the fees and expenses of such counsel related to such proceeding, as incurred. In any such proceeding, any Indemnified Person 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 Person unless (i) the Indemnifying Person and the Indemnified Person shall have mutually agreed to the contrary; (ii) the Indemnifying Person has failed within a reasonable time to retain counsel reasonably satisfactory to the Indemnified Person; (iii) the Indemnified Person shall have reasonably concluded that there may be legal defenses available to it that are different from or in addition to those available to the Indemnifying Person; or (iv) the named parties in any such proceeding (including any impleaded parties) include both the Indemnifying Person and the Indemnified Person and representation of both parties by the same counsel would be inappropriate due to actual or potential differing interest between them. It is understood and agreed that the Indemnifying Person shall not, in connection with any proceeding or related proceedings in the same jurisdiction, be liable for the fees and expenses of more than one separate firm (in addition to any local counsel) for all Indemnified Persons, and that all such fees and expenses shall be paid or reimbursed as they are incurred. Any such separate firm for any Underwriter, its affiliates, directors and officers and any control persons of such Underwriter shall be designated in writing by the Representative, any such separate firm for the Company, its directors, its officers who signed the Registration Statement and any control persons of the Company shall be designated in writing by the Company. The Indemnifying Person 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 Person agrees to indemnify each Indemnified Person from and against any loss or liability by reason of such settlement or judgment. Notwithstanding the foregoing sentence, if at any time an Indemnified Person shall have requested that an Indemnifying Person reimburse the Indemnified Person for fees and expenses of counsel as contemplated by this paragraph, the Indemnifying Person 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 the Indemnifying Person of such request and (ii) the Indemnifying Person shall not have reimbursed the Indemnified Person in accordance with such request prior to the date of such settlement. No Indemnifying Person shall, without the written consent of the Indemnified Person, effect any settlement of any pending or threatened proceeding

in respect of which any Indemnified Person is or could have been a party and indemnification could have been sought hereunder by such Indemnified Person, unless such settlement (x) includes an unconditional release of such Indemnified Person, in form and substance reasonably satisfactory to such Indemnified Person, 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 Person.

(e) Contribution. If the indemnification provided for in paragraphs (a), (b), (c) and (d) above is unavailable to an Indemnified Person or insufficient in respect of any losses, claims, damages or liabilities referred to therein, then each Indemnifying Person under such paragraph, in lieu of indemnifying such Indemnified Person thereunder, shall contribute to the amount paid or payable by such Indemnified Person 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 Company, on the one hand, and the Underwriters on the other, from the offering of the Offered ADSs or (ii) if the allocation provided by clause (i) is not permitted by applicable law, in such proportion as is appropriate to reflect not only the relative benefits referred to in clause (i) but also the relative fault of the Company, on the one hand, and the Underwriters on the other 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, on the one hand, and the Underwriters on the other, shall be deemed to be in the same respective proportions as the net proceeds (before deducting expenses) received by the Company from the sale of the Offered ADSs and the total underwriting discounts and commissions received by the Underwriters in connection therewith, in each case as set forth in the table on the cover of the Prospectus, bear to the aggregate offering price of the Offered ADSs. The relative fault of the Company, on the one hand, and the Underwriters on the other, 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 or by the Underwriters and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission.

(f) Limitation on Liability. The Company and the Underwriters agree that it would not be just and equitable if contribution pursuant to this Section 8 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 paragraph (e) above. The amount paid or payable by an Indemnified Person as a result of the losses, claims, damages and liabilities referred to in paragraph (e) above shall be deemed to include, subject to the limitations set forth above, any legal or other expenses incurred by such Indemnified Person in connection with any such action or claim. Notwithstanding the provisions of this Section 8, 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 ADSs 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 Underwriters’ obligations to contribute pursuant to this Section 8 are several in proportion to their respective purchase obligations hereunder and not joint.

(g) Non-Exclusive Remedies. The remedies provided for in this Section 8 are not exclusive and shall not limit any rights or remedies which may otherwise be available to any Indemnified Person at law or in equity.

9. Effectiveness of Agreement. This Agreement shall become effective upon the execution and delivery hereof by the parties hereto.

10. Termination. This Agreement may be terminated in the absolute discretion of the Representative, by notice to the Company, the Founders, if after the execution and delivery of this Agreement and prior to the Closing Date or, in the case of the Option ADSs, prior to the Additional Closing Date (i) trading generally shall have been suspended or materially limited on or by any of the NYSE, the American Stock Exchange, The Nasdaq Stock Market, the Chicago Board Options Exchange, the Chicago Mercantile Exchange or the Chicago Board of Trade, or the Stock Exchange of Hong Kong a.k.a. the SEHK; (ii) trading of any securities issued or guaranteed by the Company shall have been suspended on any exchange or in any over-the-counter market; (iii) a general moratorium on commercial banking activities shall have been declared by federal, New York State or PRC authorities; or (iv) there shall have occurred any outbreak or escalation of hostilities or any change in financial markets or any calamity or crisis, either within or outside the United States and the PRC, that, in the judgment of the Representative, is material and adverse and makes it impracticable or inadvisable to proceed with the offering, sale or delivery of the Shares or Offered ADSs on the Closing Date or the Additional Closing Date, as the case may be, on the terms and in the manner contemplated by this Agreement, the Pricing Disclosure Package and the Prospectus.

11. Defaulting Underwriter.

(a) If, on the Closing Date or the Additional Closing Date, as the case may be, any Underwriter defaults on its obligation to purchase the ADSs that it has agreed to purchase hereunder on such date, the non-defaulting Underwriters may in their discretion arrange for the purchase of such ADSs by other persons satisfactory to the Company on the terms contained in this Agreement. If, within 36 hours after any such default by any Underwriter, the non-defaulting Underwriters do not arrange for the purchase of such ADSs, then the Company shall be entitled to a further period of 36 hours within which to procure other persons satisfactory to the non-defaulting Underwriters to purchase such ADSs on such terms. If other persons become obligated or agree to purchase the ADSs of a defaulting Underwriter, either the non-defaulting Underwriters or the Company may postpone the Closing Date or the Additional Closing Date, as the case may be, for up to five full business days in order to effect any changes that in the opinion of counsel for the Company or counsel for the Underwriters may be necessary in the Registration Statement and the Prospectus or in any other document or arrangement, and the Company agrees to promptly prepare any amendment or supplement to the Registration Statement and the Prospectus that effects any such changes. As used in this Agreement, the term “Underwriter” includes, for all purposes of this Agreement unless the context otherwise requires, any person not listed in Schedule 1 hereto that, pursuant to this Section 11, purchases ADSs that a defaulting Underwriter agreed but failed to purchase.

(b) If, after giving effect to any arrangements for the purchase of the ADSs of a defaulting Underwriter or Underwriters by the non-defaulting Underwriters, the Company as provided

in paragraph (a) above, the aggregate number of ADSs that remain unpurchased on the Closing Date or the Additional Closing Date, as the case may be, does not exceed one-eleventh of the aggregate number of ADSs to be purchased on such date, then the Company shall have the right to require each non-defaulting Underwriter to purchase the number of ADSs that such Underwriter agreed to purchase hereunder on such date plus such Underwriter’s pro rata share (based on the number of ADSs that such Underwriter agreed to purchase on such date) of the ADSs of such defaulting Underwriter or Underwriters for which such arrangements have not been made.

(c) If, after giving effect to any arrangements for the purchase of the ADSs of a defaulting Underwriter or Underwriters by the non-defaulting Underwriters, the Company as provided in paragraph (a) above, the aggregate number of ADSs that remain unpurchased on the Closing Date or the Additional Closing Date, as the case may be, exceeds one-eleventh of the aggregate amount of ADSs to be purchased on such date, or if the Company shall not exercise the right described in paragraph (b) above, then this Agreement or, with respect to any Additional Closing Date, the obligation of the Underwriters to purchase ADSs on the Additional Closing Date, shall terminate without liability on the part of the non-defaulting Underwriters. Any termination of this Agreement pursuant to this Section 11 shall be without liability on the part of the Company, except that the Company will continue to be liable for the payment of expenses as set forth in Section 12 hereof and except that the provisions of Section 8 hereof shall not terminate and shall remain in effect.

(d) Nothing contained herein shall relieve a defaulting Underwriter of any liability it may have to the Company or any non-defaulting Underwriter for damages caused by its default.

12. Payment of Expenses.

(a) Whether or not the transactions contemplated by this Agreement are consummated or this Agreement is terminated, the Company will pay or cause to be paid all costs and expenses incident to the performance of its obligations hereunder, including without limitation, (i) the costs incident to the authorization, issuance, sale, preparation and delivery of the ADSs and any taxes payable in that connection; (ii) the costs incident to the preparation, printing and filing under the Securities Act of the Registration Statement, the Preliminary Prospectus, any Issuer Free Writing Prospectus, the Pricing Disclosure Package and the Prospectus (including all exhibits, amendments and supplements thereto) and the distribution thereof; (iii) the costs of reproducing and distributing each of the Transaction Documents; (iv) the fees and expenses of the Company’s counsel and independent accountants; (v) the fees and expenses incurred in connection with the registration or qualification and determination of eligibility for investment of the ADSs under the state or foreign securities or blue sky laws of such jurisdictions as the Representative may designate and the preparation, printing and distribution of a Blue Sky Memorandum (including the related fees and expenses of counsel for the Underwriters) for no more than $25,000; (vi) the cost of preparing stock certificates; (vii) the costs and charges of any transfer agent and any registrar; (viii) all expenses and application fees incurred in connection with any filing with, and clearance of the offering by, FINRA; and (ix) all expenses incurred by the Company in connection with any “road show” presentation to potential investors; (x) all expenses and application fees related to the listing of the ADSs on the NYSE.

(b) If (i) this Agreement is terminated pursuant to Section 10, (ii) the Company for any reason fail to tender the ADSs for delivery to the Underwriters or (iii) the Underwriters decline to purchase the ADSs for any reason permitted under this Agreement, the Company agree to reimburse the Underwriters for all out-of-pocket costs and expenses (including the fees and expenses of their counsel) reasonably incurred by the Underwriters in connection with this Agreement and the offering contemplated hereby.

13. Persons Entitled to Benefit of Agreement. This Agreement shall inure to the benefit of and be binding upon the parties hereto and their respective successors and the officers and directors and any controlling persons referred to in Section 8 hereof. Nothing in this Agreement is intended or shall be construed to give any other person any legal or equitable right, remedy or claim under or in respect of this Agreement or any provision contained herein. No purchaser of ADSs from any Underwriter shall be deemed to be a successor merely by reason of such purchase.

14. Survival. The respective indemnities, rights of contribution, representations, warranties and agreements of the Company, the Founders and the Underwriters contained in this Agreement or made by or on behalf of the Company, the Founders or the Underwriters pursuant to this Agreement or any certificate delivered pursuant hereto shall survive the delivery of and payment for the ADSs and shall remain in full force and effect, regardless of any termination of this Agreement or any investigation made by or on behalf of the Company, the Founders or the Underwriters.

15. Certain Defined Terms. For purposes of this Agreement, (a) except where otherwise expressly provided, the term “affiliate” has the meaning set forth in Rule 405 under the Securities Act; (b) the term “business day” means any day other than a day on which banks are permitted or required to be closed in New York City; and (c) the term “subsidiary” has the meaning set forth in Rule 405 under the Securities Act.

16. Submission to Jurisdiction; Appointment of Agent for Service.

(a) Each of the Company, the Founders irrevocably submits to the non-exclusive jurisdiction of any New York State or United States Federal court sitting in The City of New York over any suit, action or proceeding arising out of or relating to this Agreement, the Pricing Disclosure Package, the Prospectus, the Registration Statement, the ADS Registration Statement or the offering of the ADSs. Each of the Company, the Founders irrevocably waives, to the fullest extent permitted by law, any objection which it may now or hereafter have to the laying of venue of any such suit, action or proceeding brought in such a court and any claim that any such suit, action or proceeding brought in such a court has been brought in an inconvenient forum. To the extent that any of the Company, the Founders has or hereafter may acquire any immunity (on the grounds of sovereignty or otherwise) from the jurisdiction of any court or from any legal process with respect to itself or its property, each of the Company, such Founder, as applicable, irrevocably waives, to the fullest extent permitted by law, such immunity in respect of any such suit, action or proceeding.

(b) Each of the Company and the Founders hereby irrevocably appoints Law Debenture as their respective agents for service of process in any suit, action or proceeding described in

the preceding paragraph and agrees that service of process in any such suit, action or proceeding may be made upon it at the office of such agent. Each of the Company, the Founders waives, to the fullest extent permitted by law, any other requirements of or objections to personal jurisdiction with respect thereto. Each of the Company, the Founders represents and warrants that such agent has agreed to act as its agent for service of process, and each of the Company, the Founders agrees to take any and all action, including the filing of any and all documents and instruments, that may be necessary to continue such appointment in full force and effect.

17. 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 each of the Company, the Founders 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, each of the Company, the Founders 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, such Founder, 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.

Re: NetQin Mobile Inc. — Public Offering

Ladies and Gentlemen:

The undersigned understands that you, as Representative of the several Underwriters, propose to enter into an Underwriting Agreement (the “Underwriting Agreement”) with NetQin Mobile Inc., an exempted company limited by shares incorporated under the laws of the Cayman Islands (the “Company”), providing for the public offering (the “Public Offering”) by the several Underwriters named in Schedule 1 to the Underwriting Agreement (the “Underwriters”), of American Depositary Shares (“ADSs”) representing common shares, par value US$0.0001 per share, of the Company (the “Common Shares”). Capitalized terms used herein and not otherwise defined shall have the meanings set forth in the Underwriting Agreement.

In consideration of the Underwriters’ agreement to purchase and make the Public Offering of the ADSs, and for other good and valuable consideration receipt of which is hereby acknowledged, the undersigned hereby agrees that, without the prior written consent of the Representative on behalf of the Underwriters, the undersigned will not, during the period ending 180 days after the date of the prospectus relating to the Public Offering (the “Prospectus”), (1) offer, pledge, announce the intention to sell, 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 Common Shares, ADSs or any securities convertible into or exercisable or exchangeable for Common Shares or ADSs (including without limitation, Common Shares which may be deemed to be beneficially owned by the undersigned in accordance with the rules and regulations of the United States Securities and Exchange Commission and securities which may be issued upon exercise of a stock option or warrant)

or (2) enter into any swap or other agreement that transfers, in whole or in part, any of the economic consequences of ownership of the Common Shares or ADSs, whether any such transaction described in clause (1) or (2) above is to be settled by delivery of Common Shares or ADSs or such other securities, in cash or otherwise, in each case other than (A) the ADSs and the Common Shares represented thereby to be sold by the undersigned pursuant to the Underwriting Agreement, if any, (B) transfers of Common Shares as a bona fide gift or gifts, or through will or intestacy, or to an immediate family member or trust or entity beneficially owned and controlled by the undersigned, and (C) distributions of Class A Common Shares to members or stockholders of the undersigned or a transfer of Common Shares or ADSs to a partner, member or an “affiliate” of the undersigned, as such term is defined under the Securities Act of 1933, as amended; provided that in the case of any transfer or distribution pursuant to clause (B) or (C), each donee or distributee shall execute and deliver to the Representative a lock-up letter in the form of this paragraph; and provided, further, that in the case of any transfer or distribution pursuant to clause (B) or (C), no filing by any party (donor, donee, transferor or transferee) under the Securities Exchange Act of 1934, as amended, or other public announcement shall be required or shall be made voluntarily in connection with such transfer or distribution (other than a filing on a Schedule 13D or 13G to the extent required by law). In addition, the undersigned agrees that, without the prior written consent of the Representative on behalf of the Underwriters, it will not, during the period ending 180 days after the date of the Prospectus, make any demand for or exercise any right with respect to, the registration of any Common Shares or ADSs or any security convertible into or exercisable or exchangeable for Common Shares or ADSs. Notwithstanding the foregoing, if (1) during the last 17 days of the 180-day restricted period, the Company issues an earnings release or announces material news or a material event relating to the Company occurs; or (2) prior to the expiration of the 180-day restricted period, the Company announces that it will release earnings results during the 16-day period beginning on the last day of the 180-day period, the restrictions imposed by this agreement shall continue to apply until the expiration of the 18-day period beginning on the issuance of the earnings release or the announcement of the material news or the occurrence of the material event.

In furtherance of the foregoing, the Company, the Depositary and any duly appointed transfer agent for the registration or transfer of the securities described herein are hereby authorized to decline to make any transfer of securities if such transfer would constitute a violation or breach of this agreement.

The undersigned hereby represents and warrants that the undersigned has full power and authority to enter into this agreement. All authority herein conferred or agreed to be conferred and any obligations of the undersigned shall be binding upon the successors, assigns, heirs or personal representatives of the undersigned.

The undersigned understands that, if the Underwriting Agreement does not become effective, or if the Underwriting Agreement (other than the provisions thereof which survive termination) shall terminate or be terminated prior to payment for and delivery of the ADSs to be sold thereunder, the undersigned shall be released from all obligations under this agreement. The undersigned understands that the Underwriters are entering into the Underwriting Agreement and proceeding with the Public Offering in reliance upon this agreement.

-2-

This agreement shall be governed by and construed in accordance with the laws of the State of New York, without regard to the conflict of laws principles thereof.
