The Company held a Special Meeting of Stockholders (the “Special Meeting”) on November 9, 2012. Three matters were submitted to a vote of the stockholders at the Special Meeting. The proposals below are described in detail in the Company’s definitive proxy statement dated October 9, 2012. Abstentions and broker non-votes were counted for purposes of determining whether a quorum was present.

The stockholders approved all three proposals, as follows: (i) the issuance of 95.0 million shares of common stock of the Company in connection with the proposed merger of Badlands Power Fuels, LLC (formerly Badlands Energy, LLC) (“Power Fuels”), with an into a wholly-owned subsdiary of the Company; (ii) a reverse stock split of the Company’s common stock at a reverse split ratio within the range of 1-for-2 to 1-for-10, as and when determined by the Company’s Board of Directors in its sole discretion at any time prior to December 31, 2013, and if and when the reverse stock split is effected, to resuce the number of authorized shares of the Company’s common stock by the reverse split ratio determined by the Board of Directors; and (iii) the adjournment or postponement of the Special Meeting for a period of not more than 30 days, if necessary, to solicit additional proxies in the event that there are not sufficient votes to approve either of the foregoing proposals. Each of items (i) and (iii) brought before the stockholders at the Special Meeting requires the affirmative “FOR” vote of a majority of those shares present in person or represented by proxy and entitled to vote at the Special Meeting and item (ii) requires the affirmative “FOR” vote of a majority of the shares outstanding on the record date for the Special Meeting.

The results of the vote were as follows:
