PURCHASE AND SALE

Section 1.1 Option . Subject to the terms and conditions of this Agreement, and in reliance upon the representations and warranties set forth herein, the Company hereby grants the Option Holder an option (the “ Option ”) to purchase from the Company a number of Common Shares (the “ Purchase Shares ”) determined by dividing the total purchase price of US$20,000,007 (the “ Purchase Price ”) by the Option Exercise Price (as defined below) per share, which Option is exercisable by the Option Holder at any time on or prior to the date that is six (6) months after the date hereof (the “ Option Deadline ”). The Option will be deemed exercised upon the payment of the Purchase Price to the Company by the Option Holder. For the avoidance of doubt, the Option shall expire automatically if the Option Holder fails to exercise the Option on or prior to the Option Deadline. If the Option Holder exercises the Option, the Company shall issue, sell and deliver to the Option Holder, free and clear of any pledge, mortgage, security interest, encumbrance, lien, charge, assessment, claim or restriction of any kind or nature other than those imposed by the Articles of Incorporation and Bylaws of the Company, and the Option Holder agrees to purchase from the Company, on the Closing Date (as defined below), the Purchase Shares. The Company is not obligated to complete the sale and purchase of any Purchase Shares unless the Option is exercised by the Option Holder in full and the sale and purchase of all the Purchase Shares is completed. The number of Purchase Shares subject to the Option and the Purchase Price shall be subject to adjustment for any stock split, reverse stock split, stock dividend, recapitalization or similar event with respect to the Common Shares. The “ Option Exercise Price ” per share shall mean the price per Common Share paid by Yes Yield or its Affiliate to the Company in connection with its first tranche investment in the Company, but which shall in any event be no more than US$2.70.
