Common Stock and Warrant Issuances

During the nine months ended July 31, 2014, investors elected to convert the total outstanding $38.0 million in aggregate principal of the 8.0% Senior Unsecured Convertible Notes. As a result of these conversions, the Company issued 24,516,141 shares of common stock related to the conversions, 5,514,272 shares to settle the make-whole obligation and 250,611 shares for accrued interest.

On July 30, 2014, the Company entered into a Securities Purchase Agreement with NRG and issued 14,644,352 shares of common stock to NRG at a per share price of $2.39 for a total purchase price of $35.0 million. The per share price was equal to the per share closing NASDAQ market price on July 29, 2014. In conjunction with the sale of common stock to NRG, the Company also issued a warrant to NRG. Pursuant to the Warrant Agreement, NRG has the right to purchase up to 2.0 million shares of the Company's common stock at an exercise price of $3.35 per share. The Warrant has a term of three years from the Closing Date. The warrants qualified for permanent equity accounting treatment.

On January 23, 2014, the Company completed a public offering of 25.3 million shares of common stock, including 3.3 million shares sold pursuant to the full exercise of an over-allotment option granted to the underwriters. All shares were offered by the Company at a price of $1.25 per share. Total net proceeds to the Company were approximately $29.5 million.

The Company may sell common stock on the open market from time to time. The proceeds of these sales may be used to pay obligations related to the Company's outstanding Series I and Series B preferred shares and the 8.0% Senior Unsecured Convertible Notes or for general corporate purposes. During the nine months ended July 31, 2014, the Company sold 16,472,300 shares of the Company's common stock at prevailing market prices through periodic trades on the open market and raised approximately $34.7 million, net of fees.

On September 4, 2013, the Company entered into a co-marketing agreement with 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.
