The Funds and JAFCO shall be referred to collectively as the "INVESTORS" and individually as an "INVESTOR". WHEREAS: (A) Canadian Solar Inc. (the "COMPANY") is a corporation continued under the laws of Canada. Particulars of the Company are set out in Schedule 1. (B) The Company, the Founder, the Investors and other parties entered into (i) a subscription agreement on 16 November 2005 in relation to the issue of Convertible Notes to the Investors and (ii) four supplemental agreements relating thereto dated 28 February 2006, 29 March 2006, 9 June 2006 and the date of today respectively (collectively, the "SUBSCRIPTION AGREEMENTS"). The same parties also entered into an investment agreement relating to the Company on 30 November 2005 (the "INVESTMENT AGREEMENT"). (C) Pursuant to the Subscription Agreements, the Company issued to the Funds Convertible Notes of an aggregate principal amount of US$7,750,000 and to JAFCO Convertible Notes of an aggregate principal amount of US$4,000,000. All the Convertible Notes are outstanding as at the date hereof. (D) Each of the parties hereto acknowledges that each Investor was requested by the Company and the Founder to convert all its outstanding Convertible Notes into Common Shares, or any other Shares issued or issuable in respect thereof upon any stock split, subdivision, reorganisation or the like, or issued or issuable as stock dividend in respect of such Common Shares (the "CONVERSION SHARES") as an Optional Conversion (the "CONVERSION"). As a condition to the Conversion and in consideration of each Investor agreeing to conduct the Conversion, the Founder shall grant an option to each Investor to require the Founder to purchase all of the Conversion Shares from the relevant Investor or its Affiliate on the terms and conditions set out in this Agreement. 1 (E) It is contemplated by the parties and the Company that the Common Shares (including the Conversion Shares) will undergo a share split immediately following the Conversion, and accordingly the price for the option set out herein will be adjusted. NOW, THEREFORE, in consideration of the foregoing recitals, the mutual promises hereinafter set forth, and other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, THE PARTIES HEREBY AGREE AS FOLLOWS: 1. INTERPRETATION 1.1 In this Agreement, capitalized terms shall have the meanings as set out in the Subscription Agreements, unless otherwise defined. 1.2 In this Agreement: (A) the headings are inserted for convenience only and shall not affect the construction and interpretation of this Agreement; (B) unless the context requires otherwise, words incorporating the singular shall include the plural and vice versa and words importing a gender shall include every gender; (C) references herein to Clauses, Recitals and Schedules are to clauses and recitals of and schedules to this Agreement; and (D) all Recitals and Schedules form part of this Agreement and shall have the same force and effect as if expressly set out in the body of this Agreement and any reference to this Agreement shall include such Recitals and Schedules. 2. PUT OPTION 2.1 In consideration of each Investor agreeing to conduct the Conversion, the Founder hereby grants to each of the Investors severally an option (the "PUT OPTION") to require the Founder to purchase all of the Conversion Shares held by each Investor or its Affiliate (the "TRANSFER") at the option price ("OPTION PRICE") calculated in accordance with the following provisions: Option Price = US$5.770563156 per Conversion Share, on the basis that (i) a total of 5,668,421 Common Shares are currently in issue before the Conversion; (ii) the maximum number of Common Shares that may be issued pursuant to the ESOP shall be 1,000,000; (iii) an aggregate of 2,036,195.824 Common Shares are expected to be issued to all Investors upon the full conversion of all Convertible Notes of an aggregate principal amount of US$11,750,000. 2.2 In the event the Common Shares shall be increased by share split, subdivision, or other similar transaction into a greater number of Common Shares, the Option Price then in effect shall, concurrently with the effectiveness of such event, be decreased 2 in proportion to the percentage increase in the outstanding number of Common Shares. In the event the outstanding Common Shares shall be decreased by a reverse share split, combination, consolidation, or other similar transaction into a smaller number of Common Shares, the Option Price then in effect shall, concurrently with the effectiveness of such event, be increased in proportion to the percentage decrease in the outstanding number of Common Shares. For the avoidance of doubt, where the Common Shares shall undergo a share split immediately following the Conversion on a 1 for 1.168130772 basis and where the maximum number of Common Shares that may be issued pursuant to the ESOP shall remain 1,000,000 notwithstanding the share split: Option Price = US$4.94 per Conversion Share, on the basis that the aggregate shareholding of all Investors in the Company following the share split shall be 23.79%. 2.3 Subject to Clause 2.4 below, the Put Option may be exercisable from time to time in whole or in part. 2.4 The Put Option is exercisable by each of the Investors, by serving a written option notice (the "OPTION NOTICE") on the Founder in accordance with Clause 7 and (A) at any time from 31 March 2007 (inclusive) to 10 April 2007 (inclusive) in the event that the Company has not completed a Qualified IPO on or before 31 March 2007; or (B) at any time after the occurrence and during the continuance of an Event of Default upon written demand from any of the Investors, which demand may be served by the Investors at any time following the date on which such Event of Default becomes known to such Investor. 2.4 The Option Notice shall, concurrently with delivery to the Founder, be delivered to the other Investor(s). Upon receipt of the Option Notice, the other Investor(s) may also elect to exercise the Put Option by delivering a separate option notice ("SECOND OPTION NOTICE") to the Founder (copying all other Investors) within ten (10) days of the receipt of the Option Notice. 2.5 For the purpose of Clause 2.4(B) above, the Founder hereby undertakes with each of the Investors that upon him becoming aware of the occurrence of any Event of Default, he will promptly give written notice thereof to each of the Investors. 2.6 Any Option Notice served by any Investor pursuant to Clause 2 shall contain a statement to the effect that such Investor wishes to exercise the Put Option and shall set out in as much details as reasonably possible particulars of the event which forms the basis for the exercise of the Put Option, the number of Conversion Shares to be transferred by such Investor or its Affiliate pursuant to the said notice, the Option Price and the place where the Transfer of the Conversion Shares shall take place. 3 2.7 The completion of the Transfer of the Conversion Shares upon exercise of the Put Option by an Investor pursuant to Clauses 2.4 and/or 2.5 shall take place as soon as possible after the Investor or its Affiliate has provided the Founder with a certificate under section 116 of the Income Tax Act (Canada) as referred to in Clause 2.9, whereupon the Founder shall deliver to such Investor or its Affiliate payment of the Option Price in respect of the total number of the Conversion Shares stated in the Option Notice, or in the Second Option Notice, as the case may be. Upon receipt of the payment aforesaid, such Investor or its Affiliate shall deliver to the Founder or its nominee the relevant shares certificate(s) in respect of the said Conversion Shares and duly executed instrument of transfer. At such completion, the Investor or its Affiliate shall represent and warrant that the Conversion Shares subject to the Put Option are free and clear of all Encumbrances and Liens (other than those imposed by this Agreement, the Investment Agreement, the Registration Rights Agreement and the Articles of Incorporation and By-Laws) and that the Investor or its Affiliate has full authority to transfer such shares to the Founder or his nominee. 2.8 Provided that each Investor or its Affiliate provides the Founder with a certificate under section 116 of the Income Tax Act (Canada) with the appropriate certificate limit, the Option Price payable to any Investor or its Affiliate shall be paid to such Investor or its relevant Affiliate, by way of banker's draft or cashier's order, in United States dollars in full without any deduction or withholding for or on account of any present or future taxes, levies, imposes, duties or other charges, fees, withholdings, restrictions or conditions, and without set-off, counterclaim or any deduction whatsoever. 2.9 Where applicable, the Founder shall procure the approval of the Company's board of directors on each Transfer of the Conversion Shares. 2.10 Subject to the provisions of Clause 2.4, the parties hereto agree that there shall be no limit to the timing and numbers of Option Notices. 2.11 The right of each Investor to exercise the Put Option shall be independent of the decision of the other Investor. For avoidance of doubt, one Investor may require the Founder to complete a Transfer even if the other Investor does not so require. 2.12 The Founder agrees to bear all taxes and stamp duty, if any, payable on each Transfer. 2.13 The parties hereto acknowledge that any Transfer (a) shall be free from the transfer restrictions imposed on the Investors in the Investment Agreement but (b) shall not otherwise affect or prejudice the rights of any Investor under the Investment Agreement, the Subscription Agreements, the corresponding certificates of the Convertible Notes, the Registration Rights Agreement and the Articles of Incorporation and By-Laws. 3.
