WHEREAS, on June 29, 2011 and August 29, 2011, Seller sold 100,000 and 466,813 shares of China Wood Inc., publicly listed in the United States with the ticker symbol “CNWD” (collectively, the China Wood Shares”), and received from Buyer, common shares of Buyer;

WHEREAS, the parties now desire that Seller should guarantee that the per share 45-day volume weighted average price (“VWAP”) of the China Wood Shares will be equal to or less than US$4.00 per share;

NOW THEREFORE, for good and valuable consideration, the adequacy and receipt of which is hereby acknowledged, Buyer and Seller hereby agree as follows:

I. PRICE GUARANTY

1.01    Guaranty. Seller absolutely, unconditionally and irrevocably guarantees that the 45-day

VWAP of the China Wood Shares will not be equal to or less than US$4.50 per share.

1.02.   Repurchase Obligation. If the 45-day VWAP of the China Wood Shares is ever equal to or less than US$4.00 per share, Seller agrees to repurchase the China Wood Shares by tendering a number of shares of common stock of the Buyer back to Buyer in the following amount: 566,813 multiplied by

$4.00 divided by the 45-day VWAP of a share of Buyer’s common stock. Both parties expressly agree that (1) Seller should never have to transfer more shares of Buyer’s common stock to Buyer than Seller received as consideration for Buyer’s purchase of the China Wood Shares, and (2) notwithstanding the foregoing provisions in this paragraph, Seller shall never be obligated to transfer more than 14,481,420 shares of common stock of the Buyer back to Buyer. As an example, and not in limitation, if the 45-day VWAP of the China Wood Shares equals US$3.75 per share, and Buyer’s 45-day VWAP of its common stock is $5.00 per share, Seller shall transfer 453,450.4 shares of Buyer’s common stock back to Buyer.
