&lt;p style="TEXT-INDENT: 0.5in; MARGIN: 0in 0in 0pt;"&gt;&lt;font style="FONT-FAMILY: Times New Roman; FONT-SIZE: 10pt;" size="2"&gt;On July 10, 2013 we entered into a note exchange and subscription agreement with Very Hungry and the Scott Reiman 1991 Trust, whereby they exchanged their $5.5 million unsecured, subordinated promissory notes issued on May 2, 2013 for 5.5 million shares of a newly created senior mandatorily convertible preferred stock. The preferred stock will convert into the same units issued in our June 2013 public offering at a conversion price equal to the public offering price of $0.12 per share upon shareholder approval of the conversion and of a proposed reverse stock split of up to 50-for-one, which will be voted upon at our annual meeting of stockholders expected to be held in late August 2013. Absent obtaining stockholder approval, the preferred stock will begin to accrue dividends of 20% per annum starting December 15, 2013, increasing to 25% on June 15, 2014 and again to 30% on December 31, 2014. The preferred stock limits the voting power of all common stock and preferred stock held by the preferred stock holders to 19.99% of the outstanding voting power.&lt;/font&gt;&lt;/p&gt;

&lt;p style="TEXT-INDENT: 0.5in; MARGIN: 0in 0in 0pt;"&gt;&lt;font style="FONT-FAMILY: Times New Roman; FONT-SIZE: 10pt;" size="2"&gt;In connection with restructuring the Karlsson senior debt (as described more fully below), we were required to increase Karlsson&amp;#8217;s royalty interest from 1% to 2% without increasing the aggregate amount of royalty interests payable to third parties in the aggregate. In order to achieve this result, we negotiated with Buffalo to reduce our revenue interest to Buffalo from 2% to 1%. On August&amp;#160;14, 2013 we compensated Buffalo for this revenue interest reduction by issuing Buffalo 15.0 million shares of our newly created redeemable preferred stock and five year warrants to purchase 50,264,174 shares of our common stock at $0.144 per share.&lt;/font&gt;&lt;/p&gt;
