&lt;/table&gt;
&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 0pt"&gt;&amp;#160;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 0pt"&gt;The company has
restated it's 2012 and 2011 financial statements to correct an error in the recording of the carrying value of it's investment
in China Wood, Inc. (&amp;#34;China Wood&amp;#34;) (See Note 4).&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 0.5in"&gt;&amp;#160;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;The Company initially recorded the China Wood Shares at its fair value of $5,065,838 at the date of the transaction, based
on Viking Nevis&amp;#146;s Guaranty and Repurchase Agreement (See Note 4). Viking Nevis, on April 11, 2012, guaranteed that the
price per share of the China Wood Shares that it had previously sold to the Company in consideration of the Company issuing
Viking Nevis 14,481,420 shares of Company common stock, would not be less than $4.50 per share and agreed to repurchase the
China Wood Shares by tendering shares of common stock of Buyer owned by Viking Nevis to the Company if the 45-day volume weighted
average price (&amp;#147;VWAP&amp;#148;) of the China Wood Shares was equal to or less than US$4.00 per share. Accordingly, the
Company valued the China Wood Shares at $4.00/share and an impairment loss of $2,798,586 was recognized in the Company&amp;#146;s
previously issued consolidated financial statements for the year ended December 31, 2011.&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 0.5in"&gt;&amp;#160;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;During the three month period ended June 30, 2013, the Company re-visited the accounting treatment for the above transactions,
and determined that the exchange of China Wood shares was a nonmonetary transaction and, therefore, should be accounted under
ASC 845, "Nonmonetary Transactions." The Company further determined that the exchange of shares had no commercial substance
due to the fact that the Company&amp;#146;s future cash flows were not expected to significantly change as a result of the exchange
of shares. Therefore, the Company has now recorded the value of the China Wood Shares at their carrying value on the transaction
date, and the excess of the fair value of purchase consideration over the assets purchased was charged to additional paid
in capital. On December 31, 2011, the China Wood shares were fully impaired and charged to the income statements.&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&amp;#160;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;The Company
has amended its Annual Report on Form 10-K for the year ending December 31, 2012 to restate its financial statements for the
years ended December 31, 2011 and 2012, and will be amending its Form 10-Q for the periods ended September 30, 2011, March
31, 2012, June 30, 2012 and September 30, 2012, as well as its Annual Report on Form 10-K for the year ending December 31,
2011, to give effect to the restatement.&lt;/p&gt;
