Ladies and Gentlemen:

Canadian Solar Inc., a Canadian corporation (the “Company”), proposes to issue and sell to the Underwriters named in Schedule A hereto (each, an “Underwriter,” and together, the “Underwriters”) for whom ▇▇▇▇▇▇ ▇▇▇▇▇▇▇ & Co. Incorporated, Deutsche Bank Securities Inc. and ▇▇▇▇▇ ▇▇▇▇▇▇▇ & Co. are acting as representatives (together, the “Representatives”), an aggregate of 6,000,000 shares of common stock (the “Firm Shares”) of the Company, no par value (the “Common Shares”).

The Company also proposes to sell at the Underwriters’ option an aggregate of up to 900,000 additional Common Shares (the “Option Shares”) as set forth below. The Firm Shares and, if and to the extent such option is exercised, the Option Shares, are collectively called the “Securities.”

In consideration of the mutual agreements contained herein and of the interests of the parties in the transactions contemplated hereby, the parties hereto agree as follows:

Section 1. Representations and Warranties of the Company. The Company hereby represents, warrants and agrees with the Underwriters as follows:

(a) A shelf registration statement on Form F-3 (File No. 333-152325), as amended by post-effective amendment No. 1 thereto, which post-effective amendment includes a form of prospectus (the “Base Prospectus”), in respect of the Securities, has been prepared and filed by the Company not earlier than three years prior to the date hereof, in conformity in all material respects with the requirements of the Securities Act of 1933, as amended (the “Securities Act”) and the rules and regulations (the “Rules and Regulations”) of the Securities and Exchange Commission (the “Commission”) thereunder. Each of such registration statement and post-effective amendment No. 1 thereto has been declared effective by the Commission. The Company and the transactions contemplated by this Agreement meet the requirements and comply with the conditions for the use of Form F-3. Copies of such registration statement, including post-effective amendment No. 1 and any other amendments thereto, the Base Prospectus, as supplemented by any preliminary prospectus (including any preliminary prospectus supplement) relating to the Securities filed with the Commission pursuant to Rule 424(b) under the Securities Act, and including the documents incorporated in the Base Prospectus by reference (a “Preliminary Prospectus”), and the exhibits, financial statements and schedules to such registration statement, in each case as finally amended and revised, have heretofore been delivered by the Company to you. Such registration statement, together with any registration statement filed by the Company pursuant to Rule 462(b) under the Securities Act is herein referred to as the “Registration Statement,” which shall be deemed to include all information omitted therefrom in reliance upon Rules 430B or 430C under the Securities Act and contained in the Prospectus referred to below, and no post-effective amendment (other than post-effective amendment No. 1) to the Registration Statement has been filed as of the date of this Agreement. “Prospectus” means the form of prospectus relating to the Securities first filed with the Commission pursuant to and within the time limits described in Rule 424(b) under the Securities Act and in accordance with Section 3(a)(i) hereof. Any reference herein to the Registration Statement, any Preliminary Prospectus or to the Prospectus or to any amendment or supplement to any of the foregoing documents shall be deemed to refer to and include any documents incorporated by reference therein, and, in the case of any reference herein to the Prospectus, also shall be deemed to include any documents incorporated by reference therein, and any supplements or amendments thereto, filed with the Commission after the date of filing of the Prospectus under Rule 424(b) under the Securities Act, and prior to the termination of the offering of the Securities by the Underwriters.

(b) As of the Applicable Time (as defined below) and as of the First Closing Date or the Option Closing Date (as defined in Section 2(b) hereto, as the case may be, neither (i) the General Use Free Writing Prospectus(es) (as defined below) issued at or prior to the Applicable Time, the Statutory Prospectus (as defined below) and the information included on Schedule B hereto, all considered together (collectively, the “General Disclosure Package”), nor (ii) any individual Limited Use Free Writing Prospectus (as defined below), when considered together with the General Disclosure Package, included or will include any untrue statement of a material fact or omitted or will omit to state a material fact necessary in order to make the

statements therein, in the light of the circumstances under which they were made, not misleading provided, however, that the Company makes no representations or warranties as to information contained in or omitted from the General Disclosure Package or any Issuer Free Writing Prospectus, in reliance upon, and in conformity with, written information furnished to the Company by or on behalf of any Underwriter through the Representatives, specifically for use therein, it being understood and agreed that the only such information is that described in Section 6(f) herein. As used in this subsection and elsewhere in this Agreement:

“Applicable Time” means 9:00 p.m. (New York time) on the date of this Agreement or such other time as agreed to by the Company and the Representatives.

“Statutory Prospectus” means the Base Prospectus, as amended and supplemented immediately prior to the Applicable Time, including any document incorporated by reference therein and any prospectus supplement deemed to be a part thereof.

“Issuer Free Writing Prospectus” means any “issuer free writing prospectus,” as defined in Rule 433 under the Securities Act, relating to the Securities in the form filed or required to be filed with the Commission or, if not required to be filed, in the form retained in the Company’s records pursuant to Rule 433(g) under the Securities Act.

“General Use Free Writing Prospectus” means any Issuer Free Writing Prospectus that is identified on Schedule B to this Agreement.

“Limited Use Free Writing Prospectus” means any Issuer Free Writing Prospectus that is not a General Use Free Writing Prospectus.

(c) The Commission has not issued an order preventing or suspending the use of any Preliminary Prospectus, any Issuer Free Writing Prospectus or the Prospectus, or the effectiveness of the Registration Statement, relating to the proposed offering of the Securities, and no proceeding for that purpose or pursuant to Section 8A of the Securities Act has been instituted or, to the Company’s knowledge, threatened by the Commission. The Registration Statement contains, and the Prospectus and any amendments or supplements thereto will contain, all statements which are required to be stated therein by, and will conform to, the requirements of the Securities Act and the Rules and Regulations. The documents incorporated, or to be incorporated, by reference in the Prospectus, at the time filed with the Commission conformed or will conform, in all respects to the requirements of the Securities Exchange Act of 1934 (“Exchange Act”) or the Securities Act, as applicable, and the rules and regulations of the Commission thereunder. (i) At the time the Registration Statement initially became effective, (ii) at the time of each amendment thereto for the purposes of complying with Section 10(a)(3) of the Securities Act (whether by post-effective amendment, incorporated report or form of prospectus), (iii) at the time of the first contract of sale for the Securities and (iv) on the Closing Date, the Registration Statement and any amendment thereto do not contain, and will not contain, any untrue statement of a material fact and do not omit, and will not omit, to state a material fact required to be stated therein or necessary to make the statements therein not misleading.

(d) Each Issuer Free Writing Prospectus, as of its issue date and at all subsequent times through the completion of the public offer and sale of the Securities or until any earlier date that the Company notified or notifies the Representatives as described in the next sentence, did not, does not and will not include any information that conflicted, conflicts or will conflict with the information contained in the Registration Statement or the Prospectus, including any document incorporated by reference deemed to be a part thereof that has not been superseded or modified. If at any such time following issuance of an Issuer Free Writing Prospectus there occurred or occurs an event or development as a result of which such Issuer Free Writing Prospectus conflicted or would conflict with the information then contained in any part of the Registration Statement or as a result of which such Issuer Free Writing Prospectus, if republished immediately following such event or development, would include an untrue statement of a material fact or omitted or would omit to state a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading, (i) the Company has promptly notified or will promptly notify the Representatives and (ii) the Company has promptly amended or will promptly amend or supplement such Issuer Free Writing Prospectus to eliminate or correct such conflict, untrue statement or omission.

(e) The Company has not, directly or indirectly, distributed and will not, prior to the later of the final Closing Date or completion of the distribution of the Securities, distribute any offering material in connection with the offering and sale of the Securities other than any Preliminary Prospectus, the Prospectus and other materials, if any, permitted under the Securities Act and consistent with Section 3(b) hereof. The Company will file with the Commission all Issuer Free Writing Prospectuses in the time and manner required under Rules 163(b)(2) and 433(d) under the Securities Act.

(f) At the earliest time after the filing of the Registration Statement that the Company or another offering participant made a bona fide offer (within the meaning of Rule 164(h)(2) under the Securities Act) of the Securities and (ii) as of the date hereof (with such date being used as the determination date for purposes of this clause (ii)), the Company was not and is not an “ineligible issuer” (as defined in Rule 405 under the Securities Act, without taking into account any determination by the Commission pursuant to Rule 405 under the Securities Act that it is not necessary that the Company be considered an ineligible issuer).

(rr) Except as disclosed in the General Disclosure Package and the Prospectus, since the most recent balance sheet of the Company and its consolidated Subsidiaries reviewed or audited by Deloitte Touche Tohmatsu CPA Ltd. and the audit committee of the board of directors of the Company, there has been (i) no material weakness in the Company’s internal control over financial reporting (whether or not remediated), (ii) no significant deficiencies in the design or operation of internal controls that could adversely affect the ability of the Company and each of the Subsidiaries to record, process, summarize and report financial data, and (iii) no change in the internal controls or in other factors that could significantly affect internal controls, including any corrective actions with regard to significant deficiencies and material weaknesses.

(ss) As of the date of this Agreement, there is no failure on the part of the Company and any of the Company’s directors or officers, in their capacities as such, to comply with the provisions of the ▇▇▇▇▇▇▇▇-▇▇▇▇▇ Act of 2002 (the “▇▇▇▇▇▇▇▇-▇▇▇▇▇ Act”) and the rules and regulations of the Commission promulgated thereunder.

The Company’s board of directors and senior management have reviewed and agreed with the selection, application and disclosure of the Critical Accounting Policies and have consulted with the Company’s independent accountants with regard to such disclosure.

(uu) The Company is a “foreign private issuer” as defined in Rule 405 under the Securities Act.

(vv) The choice of the laws of the State of New York as the governing law of this Agreement is a valid choice of law under the laws of Canada and will be honored by courts in Canada, provided that such choice of law is bone fide (in the sense that it was not made with a view to avoiding the consequences of the laws of any other jurisdiction) and legal and provided that such choice of law is not contrary to public policy. The Company has the corporate power and capacity to submit, and, pursuant to Section 14 of this Agreement, has legally, validly, effectively and irrevocably submitted, to the personal jurisdiction of any court of the State of New York or the United States located in the Borough of Manhattan, The City of New York (each, a “New York Court”) and has validly and irrevocably waived any objection to the laying of venue of any suit, action or proceeding brought in any such court; and the Company has the power to designate, appoint and authorize, and pursuant to Section 14 of this Agreement has legally, validly, effectively and irrevocably designated, appointed and authorized, an authorized agent for service of process in any action arising out of or relating to this Agreement, the Registration Statement, the General Disclosure Package or the Prospectus or the offering of the Securities in any New York Court, and service of process effected on such authorized agent will

be effective to confer valid personal jurisdiction over the Company as provided in Section 14 of this Agreement.

(ww) This Agreement is in proper form to be enforceable in Canada in accordance with its terms; to ensure the legality, validity, enforceability or admissibility into evidence in Canada of this Agreement it is not necessary that this Agreement be filed or recorded with any court or other authority in Canada (other than court filings in the ordinary course of proceedings) or that any stamp or similar tax in Canada (other than nominal stamp or similar tax payable in the ordinary course of proceedings) be paid on or in respect of this Agreement or any other documents to be furnished hereunder or thereunder.

(xx) Any final judgment for a fixed or readily calculable sum of money rendered by a New York Court having jurisdiction under its own domestic laws in respect of any suit, action or proceeding against the Company based upon this Agreement and any instruments or agreements entered into for the consummation of the transactions contemplated herein that is not impeachable as void or voidable under the laws of the State of New York would be recognized and enforced against the Company without re-examination of the merits of the cause of action in respect of which the original judgment was given or re-litigation of the matters adjudicated upon or payment of any stamp, registration or similar tax or duty by the courts of Ontario (other than in the normal course of proceeding), provided that (A) such New York courts had proper jurisdiction over the parties subject to such judgment; (B) such judgment was not obtained by fraud or in a manner contrary to natural justice; (C) the enforcement of the judgment would not be contrary to public policy as such term is understood under the laws of Ontario or contrary to any order made by the Attorney General of Canada under the Foreign Extra-Territorial Measures Act (Canada); (D) no new admissible evidence relevant to the action is submitted prior to the rendering of the judgment by the courts of Canada; (E) there is due compliance with the correct procedures under the laws of Canada; (F) the enforcement of such judgment does not constitute directly or indirectly the enforcement of revenue expropriatory or penal laws; and (G) the action to enforce such judgment is commenced within the applicable limitation period under the laws of Ontario. The Company is not aware of any reason why the enforcement in Canada of such a New York Court judgment would be, as of the date hereof, contrary to public policy of Canada or contrary to the public policy, state sovereignty or security of the PRC. This Section 1(xx) is subject in its entirety to the following qualifications and exceptions: (i) an Ontario Court has discretion to stay or decline to hear an action on a New York judgment if the New York Judgment is under appeal or there is another subsisting judgment in any jurisdiction relating to the same cause of action, (ii) an Ontario court will render judgment only in Canadian dollars, and (iii) an action in an Ontario Court on a New York judgment may be affected by bankruptcy, insolvency or other similar laws affecting the enforcement of creditor’s rights generally.

listing purposes and controlled directly or indirectly by PRC companies or individuals, to obtain the approval of the CSRC prior to the listing and trading of their securities on an overseas stock exchange; the Company has received legal advice specifically with respect to the M&A Rules from its PRC counsel and the Company understands such legal advice.

(zz) Based on the advice of the Company’s PRC counsel, the Company believes the issuance and sale of the Securities, the listing and trading of the Securities on the Nasdaq Global Market or the consummation of the transactions contemplated by this Agreement is not and will not be, as of the date hereof or at the First Closing Date or at any Option Closing Date, subject to or adversely affected by the M&A Rules or any official clarifications, guidance, interpretations or implementation rules in connection with or related to the M&A Rules, including the clarification and notices issued by the CSRC on September 21, 2006 (the “M&A Rules and Related Clarifications”).

(aaa) The Company has taken all reasonable steps to comply with, and all reasonable steps to ensure compliance by all of the Company’s shareholders and option holders who are PRC residents or PRC citizens with any applicable rules and regulations of the State Administration of Foreign Exchange (the “SAFE Rules and Regulations”), including without limitation, requiring each shareholder and option holder that is, or is directly or indirectly owned or controlled by, a PRC resident or PRC citizen to complete any registration and other procedures required under applicable SAFE Rules and Regulations.

(bbb) For the purposes of this Agreement, the term “Material Contract” shall refer to any agreement or instrument that would be expected to have a material effect on the condition (financial or otherwise), results of operations, shareholders’ equity, properties, management, business or prospects of the Company or and its Subsidiaries, taken as a whole. Material Contracts shall include, but not be limited to, the agreements and instruments that were filed or incorporated by reference as exhibits to the Company’s most recent Annual Report on Form 20-F. Neither the Company nor any of the Subsidiaries has sent or received any communication regarding termination of, or intent not to renew, any of the Material Contracts (other than purchase orders and supply contracts), and no such termination or non-renewal has been threatened by the Company or any of the Subsidiaries or, to the Company’s knowledge, any other party to any Material Contract (other than purchase orders and supply contracts). No purchase orders that constitute Material Contracts have been cancelled since January 1, 2009 except as set forth on Schedule D.

(ccc) Except as disclosed in the General Disclosure Package, there are no contracts, agreements or understandings between the Company and any person that would give rise to a valid claim against the Company or any Underwriter for a brokerage commission, finder’s fee or other like payment in connection with this offering.

(ddd) Except as described in the General Disclosure Package and the Registration Statement, there are no persons with registration rights or other similar rights to have any securities registered pursuant to the Registration Statement or otherwise registered by the Company under the Securities Act.

(eee) The Securities have been approved for listing on the Nasdaq Global Market, subject only to notice of issuance, and all issued and outstanding Common Shares are duly listed on the Nasdaq Global Market.

Any certificate signed by any officer of the Company and delivered to the Representatives or counsel for the Underwriters in connection with the offering of the Securities shall be deemed a representation and warranty by the Company, as to the matters covered thereby, to the Underwriters.

Section 2. Purchase, Sale and Delivery of Securities.

(a) On the basis of the representations, warranties and agreements herein contained, but subject to the terms and conditions herein set forth, the Company agrees to issue and sell the Firm Shares to the Underwriters, and each of the Underwriters agree, severally and not jointly, to purchase from the Company, at a price of $14.97825 per share (the “Purchase Price”), the number of Firm Shares set forth opposite the name of each Underwriter in Schedule A, subject to adjustments in accordance with Section 7 hereof.

The Firm Shares will be delivered by the Company to the account of ▇▇▇▇▇▇ ▇▇▇▇▇▇▇ & Co. Incorporated, for the account of each Underwriter, against payment of the Purchase Price therefor by wire transfer of same day funds payable to the order of the Company, by causing The Depository Trust Company (“DTC”) or its designated custodian (the “Custodian”) to credit the Firm Shares to the account of ▇▇▇▇▇▇ ▇▇▇▇▇▇▇ & Co. Incorporated at DTC, at 9:00 a.m., New York City time, on October 21, 2009, or at such other time and date as the Representatives and the Company determine pursuant to Rule 15c6-1(a) under the Exchange Act, such time and date of delivery being herein referred to as the “First Closing Date.”

(b) On the basis of the representations, warranties and agreements herein contained, and subject to the terms and conditions herein set forth, the Company hereby grants to the Underwriters an option to purchase the Option Shares at the price per share as set forth in the first paragraph of this Section 2, at their election within a period of 30 days beginning with the date of this Agreement. The option granted hereunder may be exercised in whole or in part from time to time within 30 days after the effective date of this Agreement upon notice (confirmed in writing) by the Representatives to the Company setting forth the amount of Option Shares to be purchased and the date and time, as determined by the Representatives, when the Option Shares are to be delivered, such date and time being herein referred to as an “Option Closing” and “Option Closing Date” (the First Closing Date and any Option Closing Date each being herein referred to as a “Closing Date”), respectively; provided, however, that no Option Closing Date shall be earlier than the First Closing Date nor, unless waived by the Company and the Representatives, earlier than the second business day after the date on which such notice is delivered by the Representatives. Such Option Shares shall be purchased from the Company for the account of each Underwriter in the same proportion as the number of Firm Shares set forth opposite such Underwriter’s name in Schedule A hereto bears to the total number of Firm Shares (subject to adjustment by the Representatives to eliminate fractions). No Option Shares shall be sold and delivered unless the Firm Shares previously have been, or simultaneously are, sold and delivered.

The Option Shares will be delivered by the Company to the account of ▇▇▇▇▇▇ ▇▇▇▇▇▇▇ & Co. Incorporated, for the account of each Underwriter, against payment of the purchase price therefor by wire transfer of same day funds payable to the order of the Company, by causing

DTC or its Custodian to credit the Option Shares to the account of ▇▇▇▇▇▇ ▇▇▇▇▇▇▇ & Co. Incorporated at DTC, on each Option Closing Date.

The Company will use its best efforts to obtain as soon as possible the withdrawal of any such stop order, if issued.

(d) The Company shall take or cause to be taken all necessary action to qualify the Securities for sale under the securities laws of such jurisdictions as the Representatives reasonably designate and to continue such qualifications in effect so long as required for the distribution of the Securities, except that the Company shall not be required in connection therewith to (i) qualify as a foreign corporation in any jurisdiction in which it would not otherwise be required to so qualify, (ii) to execute a general consent to service of process in any jurisdiction or (iii) to subject itself to taxation in any jurisdiction in which it would not otherwise be subject.

(f) The Company will comply with the Securities Act and the Exchange Act so as to permit the completion of the distribution of the Securities as contemplated in this Agreement and the Prospectus. If during the Prospectus Delivery Period, any event shall occur as a result of which, in the judgment of the Company or in the reasonable opinion of the Underwriters, it becomes necessary to amend or supplement the Prospectus in order to make the statements therein, in the light of the circumstances existing at the time the Prospectus is delivered to a purchaser, not misleading, or, if it is necessary at any time to amend or supplement the Prospectus to comply with any law, the Company promptly will either (i) prepare and file with the Commission an appropriate amendment to the Registration Statement or supplement to the Prospectus or (ii) prepare and file with the Commission an appropriate filing under the Exchange Act which shall be incorporated by reference in the Prospectus so that the Prospectus as so amended or supplemented will not, in the light of the circumstances when it is so delivered, be misleading, or so that the Prospectus will comply with the law.

(g) If the General Disclosure Package is being used to solicit offers to buy the Securities at a time when the Prospectus is not yet available to prospective purchasers and any event shall occur as a result of which, in the judgment of the Company or the Underwriters, it becomes necessary to amend or supplement the General Disclosure Package in order to make the statements therein, in the light of the circumstances, not misleading, or to make the statements therein not conflict with the information contained in the Registration Statement then on file, or if it is necessary at any time to amend or supplement the General Disclosure Package to comply with any law, the Company promptly will either (i) prepare, file with the Commission (if

(r) The Company will indemnify and hold the Underwriters harmless against any documentary, stamp or similar issuance or transfer taxes, duties or fees and any transaction levies, including any interest and penalties, which are or may be required to be paid in connection with the creation, allotment, issuance, offer and distribution of the Securities and the execution and delivery of this Agreement; provided, however, that the Company shall not be responsible for any such taxes, duties, fees, levies or charges that arise as a result of the distribution of the Securities by the Underwriters in a manner other than that as is customary in such transactions.

(ii) Each Representative, severally and not jointly, represents and agrees that, unless it obtains the prior consent of the Company, such Representative has not made and will not make any offer relating to the Securities that would constitute an Issuer Free Writing Prospectus or that would otherwise constitute a “free writing prospectus” (as defined in Rule 405 under the Securities Act) required to be filed with the Commission under Rule 433 under the Securities Act unless the Company approves its use in writing prior to the first use; provided that the prior written consent of the Company hereto shall be deemed to have been given in respect of the Issuer Free Writing Prospectus(es) included in Schedule B hereto.

Section 4. Offering by the Underwriters. It is understood that the several Underwriters are to make a public offering of the Firm Shares as soon as the Representatives deem it advisable to do so. The Firm Shares are to be initially offered to the public at the initial public offering price set forth on the cover of the Prospectus. The Representatives may from time to time thereafter change the public offering price and other selling terms.

Section 5. Conditions of Underwriters’ Obligations. The several obligations of the Underwriters hereunder are subject to the accuracy, as of the date hereof and at each of the First Closing Date and any Option Closing Date (as if made at the applicable Closing Date), of and compliance with all representations, warranties and agreements of the Company contained herein, to the performance by the Company of its obligations hereunder and to the following additional conditions:

(a) The Registration Statement and all post-effective amendments thereto shall have become effective and the Prospectus and each Issuer Free Writing Prospectus required to be filed under the Securities Act shall have been filed as required by Rules 424(b) (without reliance on Rule 424(b)(8)), 430B, 430C or 433 under the Securities Act, as applicable, within the time period prescribed by, and in compliance with in all material respects, the rules and regulations thereunder, and any request of the Commission for additional information (to be included in the Registration Statement or otherwise) shall have been disclosed to the Representatives and the Company shall have complied with such request to their reasonable satisfaction. No stop order suspending the effectiveness of the Registration Statement, as amended from time to time, shall have been issued and no proceedings for that purpose or pursuant to Section 8A of the Securities Act shall have been taken or, to the knowledge of the Company, shall be contemplated or threatened by the Commission.

Section 6. Indemnification and Contribution.

(a) The Company agrees to indemnify and hold harmless each Underwriter, 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 against any losses, claims, damages or

liabilities to which such Underwriter may become subject, under the Securities Act or otherwise (including in settlement of any litigation if such settlement is effected with the written consent of the Company), insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon an untrue statement or alleged untrue statement of a material fact contained in the Registration Statement, any Preliminary Prospectus, any Issuer Free Writing Prospectus, the Prospectus, or any amendment or supplement thereto, or in any materials or information provided to investors by, or with the approval of, the Company in connection with the marketing of the offering of the Securities (“Marketing Materials”), including any roadshow or investor presentations made to investors by the Company (whether in person or electronically) or arise out of or are based upon the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, and will reimburse each such person for any legal or other expenses reasonably incurred by it in connection with investigating or defending against such loss, claim, damage, liability or action; provided, however, that the Company shall not be liable in any such case to the extent that any such loss, claim, damage, liability or action arises out of or is based upon an untrue statement or alleged untrue statement or omission or alleged omission made in the Registration Statement, any Preliminary Prospectus, any Issuer Free Writing Prospectus, the Prospectus, or any such amendment or supplement, or in any Marketing Materials, in reliance upon and in conformity with written information furnished to the Company by or on behalf of any Underwriter through the Representatives specifically for use therein.

(b) Each Underwriter will indemnify and hold harmless the Company against any losses, claims, damages or liabilities to which the Company may become subject, under the Securities Act or otherwise (including in settlement of any litigation, if such settlement is effected with the written consent of such Underwriter), insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon an untrue statement or alleged untrue statement of a material fact contained in the Registration Statement, any Preliminary Prospectus, any Issuer Free Writing Prospectus, the Prospectus, or any amendment or supplement thereto, or arise out of or are based upon the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, in each case to the extent, but only to the extent, that such untrue statement or alleged untrue statement or omission or alleged omission was made in the Registration Statement, any Preliminary Prospectus, any Issuer Free Writing Prospectus, the Prospectus, or any amendment or supplement thereto, in reliance upon and in conformity with written information furnished to the Company by or on behalf of such Underwriter through the Representatives, specifically for use in the preparation thereof, and will reimburse the Company for any legal or other expenses reasonably incurred by the Company in connection with investigating or defending against any such loss, claim, damage, liability or action.

(c) Promptly after receipt by an indemnified party under subsection (a) or (b) above of notice of the commencement of any action, such indemnified party shall, if a claim in respect thereof is to be made against the indemnifying party under such subsection, notify the indemnifying party in writing of the commencement thereof; but the omission so to notify the indemnifying party shall not relieve the indemnifying party from any liability that it may have to any indemnified party except to the extent such indemnifying party has been materially prejudiced by such failure. In case any such action shall be brought against any indemnified party, and it shall notify the indemnifying party of the commencement thereof, the indemnifying

party shall be entitled to participate in, and, to the extent that it shall wish, jointly with any other indemnifying party similarly notified, to assume the defense thereof, with counsel satisfactory to such indemnified party, and after notice from the indemnifying party to such indemnified party of the indemnifying party’s election so to assume the defense thereof, the indemnifying party shall not be liable to such indemnified party under such subsection for any legal or other expenses subsequently incurred by such indemnified party in connection with the defense thereof other than reasonable costs of investigation.

The indemnifying party under this Section 6 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 against any loss, claim, damage, liability or expense 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 this Section 6, 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, compromise or consent to the entry of judgment in any pending or threatened action, suit or proceeding in respect of which any indemnified party is or could have been a party and indemnity was or could have been sought hereunder by such indemnified party, unless such settlement, compromise or consent (a) includes an unconditional release of such indemnified party from all liability on claims that are the subject matter of such action, suit or proceeding and (b) does not include a statement as to or an admission of fault, culpability or a failure to act by or on behalf of any indemnified party.

(d) If the indemnification provided for in this Section 6 is unavailable or insufficient to hold harmless an indemnified party under subsection (a) or (b) 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) or (b) above, (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 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 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 proportion as the total net proceeds from the offering (before deducting expenses) received by the Company bear to the total discounts received by the Underwriters, in each case as set forth in the table on the cover page of the Prospectus or in this Agreement. The relative fault 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 the Underwriters and the parties’ relevant intent, knowledge, access to information and opportunity to correct or prevent such untrue statement or omission. The Company and the Underwriters agree that it would not be just and equitable if

contributions pursuant to this subsection (d) were to be determined by pro rata allocation or by any other method of allocation which does not take account of the equitable considerations referred to in the first sentence of this subsection (d). 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 (d) shall be deemed to include any legal or other expenses reasonably incurred by such indemnified party in connection with investigating or defending against any action or claim which is the subject of this subsection (d). Notwithstanding the provisions of this subsection (d), no Underwriter shall be required to contribute any amount in excess of the amount by which the total price at which the Securities were offered 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. The Underwriters’ obligations in this subsection (d) are several in proportion to their respective underwriting obligations and not joint. 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.

(e) The obligations of the Company under this Section 6 shall be in addition to any liability which the Company may otherwise have and shall extend, upon the same terms and conditions, to each person, if any, who controls an Underwriter within the meaning of the Securities Act; and the obligations of the Underwriters under this Section 6 shall be in addition to any liability that the Underwriters may otherwise have and shall extend, upon the same terms and conditions, to each director of the Company, to each officer of the Company and to each person, if any, who controls the Company within the meaning of the Securities Act.

(f) The Underwriters confirm and the Company acknowledges that the statements with respect to the offering of the Securities by the Underwriters set forth in the first sentence of the third paragraph concerning the terms of the offering by the Underwriters and in the ninth paragraph concerning short sales, over-allotment and stabilizing transactions by the Underwriters under the section entitled “Underwriting” in the General Disclosure Package and in the Prospectus are correct and constitute the only information concerning such Underwriters furnished in writing to the Company by or on behalf of the Underwriters through the Representatives specifically for inclusion in the Registration Statement, the General Disclosure Package or the Prospectus.

Section 7. Default of Underwriters. If any one or more Underwriters defaults in its or their obligation to purchase Securities hereunder on either the First Closing Date or, if the option to purchase the Option Shares has been exercised, any Option Closing Date and the aggregate number of Securities that such defaulting Underwriter or Underwriters agreed but failed to purchase does not exceed 10% of the total number of Securities that the Underwriters are obligated to purchase on such Closing Date, the non-defaulting Underwriter or Underwriters may make arrangements satisfactory to the Company for the purchase of such Securities by other persons, including any of the Underwriters, but if no such arrangements are made by such Closing Date, the non-defaulting Underwriter or Underwriters shall be obligated severally, in proportion to their respective commitments hereunder, to purchase the Securities that such defaulting Underwriter or Underwriters agreed but failed to purchase on such Closing Date. If any Underwriter or Underwriters so default and the aggregate number of Securities with respect to which such default occurs exceeds 10% of the total number of Securities that the Underwriters

are obligated to purchase on such Closing Date and arrangements satisfactory to the non-defaulting Underwriter or Underwriters and the Company for the purchase of such 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 or the Company, except as provided in Section 8 hereof (provided that if such default occurs with respect to Option Shares after the First Closing Date, this Agreement shall not terminate as to the Firm Shares or any Option Shares purchased prior to such termination). As used in this Agreement, the term “Underwriter” includes any person substituted for an Underwriter under this Section 7. Nothing herein will relieve a defaulting Underwriter or Underwriters from liability for its default.

Section 8. Representations and Agreements to Survive Delivery. The reimbursement, indemnification and contribution agreements contained in this Agreement and the representations, warranties and covenants in this Agreement shall remain in full force and effect regardless of (a) any termination of this Agreement, (b) any investigation made by or on behalf of the Underwriters or any controlling person thereof, or the Company or any of its officers, directors or controlling persons, and (c) delivery of, and payment for, the Securities to and by the Underwriters hereunder.

Section 9. Termination of this Agreement.

(a) The Representatives, shall have the right to terminate this Agreement by giving notice to the Company as hereinafter specified at any time at or prior to the First Closing Date, and the option referred to in Section 2(b), if exercised, may be cancelled at any time prior to any Option Closing Date, if (i) the Company shall have failed, refused or been unable, at or prior to such Closing Date, to perform any agreement on its part to be performed hereunder, (ii) any condition of the Underwriters’ obligations hereunder is not fulfilled, (iii) trading in the Company’s Common Shares shall have been suspended by the Commission or the Nasdaq Stock Market or trading in securities generally on the Nasdaq Global Market, New York Stock Exchange or the American Stock Exchange shall have been suspended, (iv) minimum or maximum prices for trading shall have been fixed, or maximum ranges for prices for securities shall have been required, on the Nasdaq Global Market, New York Stock Exchange or the American Stock Exchange, by such Exchange or by order of the Commission or any other governmental authority having jurisdiction, (v) a banking moratorium shall have been declared by federal or state or local authorities in the United States, Canada or the PRC, (vi) there shall have occurred any attack on, outbreak or escalation of hostilities or act of terrorism involving the United States, Canada or the PRC, any declaration by the United States, Canada or the PRC of a national emergency or war, any change in financial markets, any substantial change or development involving a prospective substantial change in United States or international political, financial or economic conditions, or any other calamity or crisis that, in the judgment of the Representatives, is material and adverse and makes it impractical or inadvisable to proceed with the completion of the sale of and payment for the Securities. Any such termination shall be without liability of any party to any other party except that the provisions of Section 3(j) and Section 6 hereof shall at all times be effective and shall survive such termination.

(b) If the Representatives elect to terminate this Agreement as provided in this Section 9, the Company shall be notified promptly by the Representatives by telephone, confirmed by writing.

Section 10. Default by the Company.

(a) If the Company shall fail at the First Closing Date or any Option Closing Date to sell and deliver the aggregate number of Securities which it is obligated to sell hereunder, then this Agreement shall terminate without any liability on the part of the Underwriters.

(b) No action taken pursuant to this Section 10 shall relieve the Company so defaulting from liability, if any, in respect of such default.

Section 11. Notices. Except as otherwise provided herein, all communications hereunder shall be in writing and, if to the Underwriters, shall be mailed, delivered or telecopied to the Representatives at the offices set forth under the name of each Representative on Schedule A hereto, with a copy to ▇▇▇▇▇▇▇ ▇▇▇▇▇▇▇ & ▇▇▇▇▇▇▇▇ LLP, ICBC Tower, ▇▇▇▇ ▇▇▇▇▇, ▇ ▇▇▇▇▇▇ ▇▇▇▇, ▇▇▇▇▇▇▇ ▇▇▇▇ ▇▇▇▇, ▇▇▇▇▇▇▇▇▇: ▇▇▇▇▇ ▇▇▇ (telecopy no. ▇▇▇▇ ▇▇▇▇-▇▇▇▇), if to the Company, shall be mailed, delivered or telecopied to it at ▇▇. ▇▇▇ ▇▇▇▇▇▇ ▇▇▇▇, ▇▇▇▇▇▇ ▇▇▇ ▇▇▇▇▇▇▇▇, ▇▇▇▇▇▇, ▇▇▇▇▇▇▇ ▇▇▇▇▇▇▇▇ ▇▇▇▇▇▇, People’s Republic of China, Attention: Chief Financial Officer (telecopy no. ▇▇▇ (▇▇▇) ▇▇▇▇-▇▇▇▇), with a copy to ▇▇▇▇▇▇ & ▇▇▇▇▇▇▇, 8 Connaught Place, ▇▇▇▇ ▇▇▇▇▇, ▇▇▇ ▇▇▇▇▇▇▇▇ ▇▇▇▇▇▇, ▇▇▇▇▇▇▇, ▇▇▇▇ ▇▇▇▇, ▇▇▇▇▇▇▇▇▇: ▇▇▇▇▇ ▇▇▇▇▇, Esq.

Section 12. 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 assigns and the controlling persons, officers and directors referred to in Section 6. Nothing in this Agreement is intended or shall be construed to give to any other person, firm or corporation any legal or equitable remedy or claim under or in respect of this Agreement or any provision herein contained. The term “successors and assigns” as herein used shall not include any purchaser, as such purchaser, of any of the Securities from the Underwriters.

Section 13. Absence of Fiduciary Relationship. The Company acknowledges and agrees that: (a) each Underwriter has been retained solely to act as an Underwriter in connection with the sale of the Securities and that no fiduciary, advisory or agency relationship between the Company and such Underwriter has been created in respect of any of the transactions contemplated by this Agreement, irrespective of whether such Underwriter has advised or are advising the Company on other matters; (b) the price and other terms of the Securities set forth in this Agreement were established by the Company following discussions and arms-length negotiations with the several Underwriters and the Company is capable of evaluating and understanding and understands and accepts the terms, risks and conditions of the transactions contemplated by this Agreement; (c) it has been advised that each Underwriter and its affiliates are engaged in a broad range of transactions which may involve interests that differ from those of the Company and that each Underwriter has no obligation to disclose such interest and transactions to the Company by virtue of any fiduciary, advisory or agency relationship; (d) it has been advised that each Underwriter is acting, in respect of the transactions contemplated by this Agreement, solely for the benefit of such Underwriter and not on behalf of the Company; (e) it waives to the fullest extent permitted by law, any claims it may have against each Underwriter

The Company irrevocably appoints CT Corporation System, ▇▇▇ ▇▇▇▇▇▇ ▇▇▇▇▇▇, ▇▇▇ ▇▇▇▇, ▇.▇. ▇▇▇▇▇, as its authorized agent in the Borough of Manhattan, The City of New York, New York upon which process may be served in any such suit or proceeding, and agrees that service of process upon such agent, and written notice of said service to the Company by the person serving the same to the address provided in Section 11 shall be deemed in every respect effective service of process upon the Company in any such suit or proceeding. The Company further agrees to take any and all actions 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.

Section 15. Waiver of Immunity. With respect to any suit or proceeding arising out of or relating to this Agreement or the transactions contemplated hereby or thereby, each party irrevocably waives, to the fullest extent permitted by applicable law, all immunity (whether on the basis of sovereignty or otherwise) from jurisdiction, service of process, attachment (both before and after judgment) and execution to which it might otherwise be entitled, and with respect to any such suit or proceeding, each party waives any such immunity in any court of competent jurisdiction, and will not raise or claim or cause to be pleaded any such immunity at or in respect of any such suit or proceeding, including, without limitation, any immunity pursuant to the U.S. Foreign Sovereign Immunities Act of 1976, as amended.
