The Original Statement is hereby amended and restated as follows.

Item 4. Purpose of Transaction

Item 4 is amended and restated as follows:

The Common Shares held by Mr. Beaty were acquired for investment purposes only. Mr. Beaty does not have any current intention of acquiring or disposing ownership of, or control or direction over, any additional Common Shares. Depending on market conditions and other relevant factors, Mr. Beaty may, in the future, increase or decrease his beneficial ownership of, or control or direction over, Common Shares through market transactions, private agreements or otherwise.

Item 5. Interest in Securities of the Issuer

Item 5 is amended and restated as follows:

(a) As of the date hereof, Mr. Beaty beneficially owns the aggregate number and percentage of outstanding Common Shares set forth below:

Reporting Person	Aggregate Number of Shares Beneficially Owned	Percentage of Outstanding Common Shares

Ross J. Beaty	13,335,500	9.96%

The percentage of outstanding Common Shares in the table above is based on 133,933,469 Common Shares outstanding as of October 19, 2010, and is calculated pursuant to Rule 13d-3 under the U.S. Securities Exchange Act of 1934, as amended.
