The explanation as disclosed in our Form 10-Q is correctly disclosed as follows:  In February 2011, the Company issued three (3) shares of non-convertible Series A preferred stock valued at $329,000 per share, or $987,000 in aggregate, for voting purposes only, to the three (3) members of the management team at one share each. The issued and outstanding shares of the Series A preferred stock are not convertible to common stock and have voting rights equal to eighty percent (80%) of the total issued and outstanding shares of the Company's common stock.  This Form 10-Q/A should be read in conjunction with the original Form 10-Q, which continues to speak as of the date of the Form 10-Q. Except as specifically noted above, this Form 10-Q/A does not modify or update disclosures in the original Form 10-Q. Accordingly, this Form 10-Q/A does not reflect events occurring after the filing of the Form 10-Q or modify or update any related or other disclosures.   ITEM 6. EXHIBITS
