The Securities Purchase Agreement

On the Closing Date, SMC Co-Investment, SMC Reserve II, SMC Reserve II Offshore and SMC EP (collectively, the “SMC Purchasers’) along with certain other investors entered into a Securities Purchase Agreement with GreenMan whereby the SMC Purchasers acquired units comprised of one share of 10% Convertible Preferred Stock of GreenMan (“Preferred Stock”) and a warrant (“Warrant”) to purchase 25,000 shares of Common Stock of GreenMan at an initial exercise price of $0.50 per share (the “Units”), from GreenMan in exchange for the purchase price amounts set forth in Item 3 above (the “Securities Purchase Agreement’). On the Closing Date, the Spring Mountain Reporting Persons acquired, in the aggregate, 349 shares of Preferred Stock, which are immediately convertible into 8,725,000 shares of Common Stock, and Warrants exercisable for a total of 8,725,000 shares of Common Stock, for an aggregate purchase price of $3,490,000. The Warrants are exercisable for a five year period commencing on October 30, 2012.

Pursuant to the Certificate of Designation filed with the Secretary of State of the State of Delaware, setting forth the rights, preferences and privileges of the Preferred Stock (the “Certificate of Designation”), GreenMan shall pay a quarterly dividend at a rate of 10% per annum payable in cash or in shares of Common Stock at GreenMan’s option to the holders of the Preferred Stock.

As of March 31, 2013, the size of the Board shall be reduced to six directors and the holders of Common Stock voting as a separate class shall be entitled to elect three directors to the Board.
