The Company may sell common stock on the open market from time to time.

During the six months ended April 30, 2014, the Company sold 4,387,600 shares of the Company's common stock at prevailing market prices through periodic trades on the open market and raised approximately $7.7 million, net of fees.

Warrant Issuance

On September 4, 2013, the Company entered into a co-marketing agreement with NRG Energy ("NRG") for the marketing and sales of the Company's power plants. The terms of the agreement included the issuance of warrants to NRG that permit NRG to purchase up to 5.0 million shares of the Company's common stock at predetermined prices based on attaining minimum sales goals. The first tranche of 1.25 million warrants expired unvested on March 1, 2014. There are two tranches remaining of warrants with varying strike prices, varying minimum levels of qualifying orders, and different vesting and expiration dates. The weighted average strike price for the remaining 3.75 million warrants is $2.08. The qualifying order vesting dates range from December 2014 through September 2015 and the expiration dates range from December 2017 through August 2018. Any costs associated with the warrants will be recorded as a reduction of potential future revenue recorded under the arrangement. No warrants were vested and no expense was recorded as of April 30, 2014.
