The Company and the Selling Shareholders (to the extent indicated in Schedule B hereto) severally and not jointly agree to sell to the Underwriters the number of Optional Securities specified in such notice (in the event the number of Optional Securities specified in such notice is less than the total number of Optional Securities set forth in Schedule B hereto, the number of Optional Securities to be sold by the Company and the Selling Shareholders hereunder shall be reduced proportionally based on the number of Optional Securities the Company and each such Selling Shareholder has agreed to sell as set forth in Schedule B hereto), and the Underwriters agree, severally and not jointly, to purchase such Optional Securities.

No Optional Securities shall be sold or delivered unless the Firm Securities previously have been, or simultaneously are, sold and delivered.

Each time for the delivery of and payment for the Optional Securities, being herein referred to as an “Optional Closing Date”, which may be the First Closing Date (the First Closing Date and each Optional Closing Date, if any, being sometimes referred to as a “Closing Date”), shall be determined by the Representatives but shall be no later than five full business days after written notice of election to purchase Optional Securities is given. The Company and each of the Selling Shareholders (to the extent indicated in Schedule B hereto) will deliver the Optional Securities being purchased on each Optional Closing Date to or as instructed by the Representatives for the accounts of the several Underwriters in a form reasonably acceptable to the Representatives against payment at the Purchase Price per ADS in Federal (same day) funds by wire transfer to an account at a bank acceptable to the Representatives drawn to the order of the Company (for itself and as Custodian for the Selling Shareholders).

applicable law, forthwith to prepare, file with the Commission and furnish, at its own expense, to the Underwriters and to the dealers (whose names and addresses the Representatives will furnish to the Company) to which Offered Securities may have been sold by the Representatives on behalf of the Underwriters and to any other dealers upon reasonable request, either amendments or supplements to the Final Prospectus so that the statements in the Final Prospectus as so amended or supplemented will not, in the light of the circumstances when the Final Prospectus (or in lieu thereof the notice referred to in Rule 173(a) of the Act) is delivered to a purchaser, be misleading or so that the Final Prospectus, as amended or supplemented, will comply with applicable law.

All payments to be made by the Company hereunder to an Underwriter shall be made 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; provided, however, that no such additional amounts shall be paid by the Company in respect of taxes, duties or charges imposed on (i) an Underwriter (or amounts payable to such Underwriter) solely by reason of a present or former connection between such Underwriter and the applicable jurisdiction imposing such taxes, duties or charges (other than a connection arising as a result of entering into this Agreement or receiving any payments hereunder) or (ii) an Underwriter (or amounts payable to such Underwriter) as a result of any failure by such Underwriter to provide any form or certificate that such Underwriter is legally able to provide but only to the extent that, if such form or certificate had been provided, it would have reduced or eliminated such taxes, duties or charges.

(u) The Company will not (i) facilitate any shareholder’s sale or other transfer of Ordinary Shares or ADSs, or conversion of Ordinary Shares to ADSs, during the Lock-Up Period or (ii) release the Depositary from the restrictions set forth in, or otherwise amend, terminate or fail to enforce, the Depositary Letter (as defined elsewhere in this Agreement), in each case (i) and (ii), without the prior written consent of either Citigroup Global Markets Inc. or Credit Suisse Securities (USA) LLC acting on behalf of the Representatives during the Lock-Up Period; and

(f) Such Selling Shareholder (other than International Finance Corporation) agrees to pay or cause to be paid all documentary, stamp, issuance, transfer or similar taxes, if any, on the transfer and sale to the Underwriters of the Offered Shares and ADSs being sold by such Selling Shareholder. In addition, such Selling Shareholder agrees to pay or cause to be paid withholding tax, business tax, value-added tax, sales tax, applicable surcharges and all other taxes imposed on such Selling Shareholder as a result of such transfer and sale under applicable law, provided, however, that in the case of International Finance Corporation only, no tax shall be withheld out of the proceeds of any sale by the undersigned to the Underwriters unless such withholding is made based on a formal directive specific to the payment of taxes by the undersigned issued by a competent governmental authority, which directive the undersigned has taken commercially reasonable efforts to challenge but failed to have annulled. All payments to be made by such Selling Shareholder hereunder to an Underwriter shall be made 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; provided, however, that no such additional amounts shall be paid by such Selling Shareholder in respect of taxes, duties or charges imposed on (i) an Underwriter (or amounts payable to such Underwriter) solely by reason of a present or former connection between such Underwriter and the applicable jurisdiction imposing such taxes, duties or charges (other than a connection arising as a result of entering into this Agreement or receiving any payments hereunder) or (ii) an Underwriter (or amounts payable to such Underwriter) as a result of any failure by such Underwriter to

(h) Such Selling Shareholder agrees not to use any of the proceeds received by it from the sale of the Offered Shares and ADSs pursuant to this Agreement or lend, contribute or otherwise make available such proceeds to any subsidiary, joint venture partner or other Person in any manner that is not in compliance with applicable laws, rules and regulations of any governmental agency having jurisdiction over such Selling Shareholder including, if applicable, the requirement for PRC residents or citizens to repatriate the net proceeds received by such Selling Shareholder into the PRC under the applicable regulation of the Ministry of Commerce and the State Administration of Foreign Exchange of the PRC.

(i) Such Selling Shareholder agrees to pay or cause to be paid any underwriting discount and commissions payable in connection with the Offered Securities sold by such Selling Shareholder and any and all costs and expenses charged by the Depositary in connection with the conversion of the Offered Shares sold by such Selling Shareholder into ADSs.

6. Free Writing Prospectuses. The Company and the Selling Shareholders represent and agree that, unless they obtain the prior consent of the Representatives, and each Underwriter represents and agrees that, unless it obtains the prior consent of the Company and the Representatives, it has not made and will not make any offer relating to the Offered Securities that would constitute an Issuer Free Writing Prospectus, or that would otherwise constitute a “free writing prospectus,” as defined in Rule 405, required to be filed with the Commission. Any such free writing prospectus consented to by the Company and the Representatives is hereinafter referred to as a “Permitted Free Writing Prospectus.” The Company and the Selling Shareholders represent that they have treated and agree that they will treat each Permitted Free Writing Prospectus as an “issuer free writing prospectus,” as defined in Rule 433, and have complied and will comply with the requirements of Rules 164 and 433 applicable to any Permitted Free Writing Prospectus, including timely Commission filing where required, legending and record keeping.

(d) Promptly after receipt by an indemnified party under this Section of notice of the commencement of any action, such indemnified party will, if a claim in respect thereof is to be made against an indemnifying party under subsection (a), (b) or (c) above, notify the indemnifying party of the commencement thereof; but the failure to notify the indemnifying party shall not relieve it from any liability that it may have under subsection (a), (b) or (c) above 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 party shall not relieve it from any liability that it may have to an indemnified party otherwise than under subsection (a), (b), or (c) above. In case any such action is brought against any indemnified party and it notifies an indemnifying party of the commencement thereof, the indemnifying party will be entitled to participate therein and, to the extent that it may wish, jointly with any other indemnifying party similarly notified, to assume the defense

thereof, with counsel satisfactory to such indemnified party (who shall not, except with the consent of the indemnified party, be counsel to the indemnifying party), and after notice from the indemnifying party to such indemnified party of its election so to assume the defense thereof, the indemnifying party will not be liable to such indemnified party under this Section for any legal or other expenses subsequently incurred by such indemnified party in connection with the defense thereof other than reasonable costs of investigation. 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 in writing 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 conflict of 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 and their respective directors, officers, employees and agents, (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 their respective directors, officers, employees and agents 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 their respective directors, officers, employees and agents, 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 control persons and affiliates of any Underwriters and their respective directors, officers, employees and agents, 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 and their respective directors, officers, employees and agents, 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 and their respective directors, officers, employees and agents, such firm shall be designated in writing by the persons named as attorneys-in-fact, with respect to the Selling Shareholders under the Powers of Attorney. 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. No indemnifying party shall, without the prior written consent of the indemnified party, effect any settlement of any pending or threatened action 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 (i) includes an unconditional release of such indemnified party from all liability on any claims that are the subject matter of such action and (ii) does not include a statement as to, or an admission of, fault, culpability or a failure to act by or on behalf of an indemnified party.

(e) If the indemnification provided for in this Section is unavailable or insufficient to hold harmless an indemnified party under subsection (a), (b) or (c) above, then each indemnifying party shall contribute to the amount paid or payable by such indemnified party as a result of the losses, claims, damages or liabilities referred to in subsection (a), (b) or (c) above (i) in such proportion as is appropriate to reflect the relative benefits received by the Company and the Selling Shareholders on the one hand and the Underwriters on the other from the offering of the Offered Securities or (ii) if the allocation provided by clause (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 (i) above but also the relative fault of the Company and the Selling Shareholders on the one hand and the Underwriters on the other in connection with the statements or omissions which 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 in connection with the offering of the Offered Securities shall be deemed to be in the same proportion as the total net proceeds from the offering (before deducting expenses) received by the Company and the Selling Shareholders bear to the total underwriting discounts and commissions received by the Underwriters. 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 the Underwriters and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such untrue statement or omission. The amount paid by an indemnified party as a result of the losses, claims, damages or liabilities referred to in the first sentence of this subsection (e) shall be deemed to include any legal or other expenses reasonably incurred by such indemnified party in connection with investigating or defending any action or claim which is the subject of this subsection (e). Notwithstanding the provisions of this subsection (e), no Underwriter shall be required to contribute any amount in excess of the underwriting discounts and commissions applicable to the Offered Securities purchased by such Underwriter. No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. The Underwriters’ obligations in this subsection (e) to contribute are several in proportion to their respective underwriting obligations and not joint. Each Selling Shareholder’s obligations in this subsection (e) to contribute are several and not joint with the other Selling Shareholders or the Company, and each Selling Shareholder shall not be required to contribute any amount in excess of (together with any amounts payable otherwise under this Section 8) the product of (x) the number of ADSs sold by such Selling Shareholder to the Underwriters hereunder and (y) the Purchase Price as set out in this Agreement, less underwriting discounts and commissions. The Company, the Selling Shareholders and the Underwriters agree that it would not be just and equitable if contribution pursuant to this subsection (e) 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 which does not take account of the equitable considerations referred to in this subsection (e).

9. Termination. The Underwriters may terminate this Agreement by notice given by the Representatives to the Company, 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 Exchange, the American Stock Exchange or the NASDAQ Global Market, (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 Cayman Islands or the PRC shall have occurred, (iv) any moratorium on commercial banking activities shall have been declared by United States Federal, New York State, Cayman Islands or the PRC authorities 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 to proceed with the offer, sale or delivery of the Offered Securities on the terms and in the manner contemplated in the Registration Statement, the General Disclosure Package or the Final ▇▇▇▇▇▇▇▇▇▇.

▇▇

▇▇. Default of Underwriters or One or More Selling Shareholders.

(a) If any Underwriter or Underwriters default in their obligations to purchase Offered Securities hereunder on either the First or any Optional Closing Date and the aggregate number of Offered Securities that such defaulting Underwriter or Underwriters agreed but failed to purchase does not exceed 10% of the total number of Offered Securities that the Underwriters are obligated to purchase on such Closing Date, the Representatives may make arrangements satisfactory to the Company for the purchase of such Offered Securities by other persons, including any of the Underwriters, but if no such arrangements are made by such Closing Date, the non-defaulting Underwriters shall be obligated severally, in proportion to their respective commitments hereunder, to purchase the Offered Securities that such defaulting Underwriters agreed but failed to purchase on such Closing Date. If any Underwriter or Underwriters so default and the aggregate number of Offered Securities with respect to which such default or defaults occur exceeds 10% of the total number of Offered Securities that the Underwriters are obligated to purchase on such Closing Date and arrangements satisfactory to the Representatives and the Company for the purchase of such Offered Securities by other persons are not made within 36 hours after such default, this Agreement will terminate without liability on the part of any non-defaulting Underwriter, the Company or the Selling Shareholders, except as provided in Section 11 (provided that if such default occurs with respect to Optional Securities after the First Closing Date, this Agreement will not terminate as to the Firm Securities or any Optional Securities purchased prior to such termination). As used in this Agreement, the term “Underwriter” includes any person substituted for an Underwriter under this Section. Nothing herein will relieve a defaulting Underwriter from liability for its default.

(b) If a Selling Shareholder fails at a Closing Date to sell and deliver the number of Offered Securities which such Selling Shareholder is obligated to sell hereunder, and the remaining Selling Shareholders do not exercise the right hereby granted to increase, pro rata or otherwise, the number of Offered Securities to be sold by them hereunder to the total number to be sold by all Selling Shareholders as set forth in Schedule B hereto, then the Underwriters may, at option of the Representatives, by notice from the Representatives to the Company and the non-defaulting Selling Shareholders, either (i) terminate this Agreement without any liability on the fault of any non-defaulting party except that the provisions of Sections 2, 8, 11, 16, 17, 19 shall remain in full force and effect or (ii) elect to purchase the Offered Securities which the non-defaulting Selling Shareholders have agreed to sell hereunder. No action taken pursuant to this Section 10(b) shall relieve any Selling Shareholder so defaulting from liability, if any, in respect of such default. In the event of a default by any Selling Shareholder as referred to in this Section 10(b), each of the Representatives and the non-defaulting Selling Shareholders shall have the right to postpone such Closing Date for a period not exceeding seven days in order to effect any required change in the Registration Statement, the General Disclosure Package or the Final Prospectus or in any other documents or arrangements.

11. Survival of Certain Representations and Obligations. The respective indemnities, agreements, representations, warranties and other statements of the Company or its officers, of the Selling Shareholders and of the several Underwriters set forth in or made pursuant to this Agreement will remain in full force and effect, regardless of any investigation, or statement as to the results thereof, made by or on behalf of any Underwriter, the Company, any Selling Shareholder or any of their respective representatives, officers or directors or any controlling person, and will survive delivery of and payment for the Offered Securities. If the purchase of the Offered Securities by the Underwriters is not consummated for any reason other than solely because of the termination of this Agreement pursuant to Section 10 hereof, the Company will reimburse the Underwriters for all out-of-pocket expenses (including fees and disbursements of counsel) reasonably incurred by them in connection with the offering of the Offered Securities, and the respective obligations of the Company, the Selling Shareholders and the Underwriters pursuant to Section 8 hereof shall remain in effect. In addition, if any Offered Securities have been purchased hereunder, the representations and warranties in Section 2 and all obligations under Section 5 shall also remain in effect.
