Subsequent event On April 23, 2012, the Company entered into a Note and Warrant Purchase Agreement (the "Purchase Agreement") with certain investors (each an "Investor," and, collectively, the "Investors"). Under the terms of the Purchase Agreement, the Company received loans in the aggregate amount of $1,000,000 from the Investors in exchange for the Company's issuance to each of the Investors an unsecured convertible promissory note equal to the principal amount of such Investor's loan to the Company (each a "Note," and, collectively, the "Notes"). The Notes bear interest at the rate of 10% per annum, and have a maturity date of April 22, 2013. The Notes automatically convert into securities sold in the Company's next equity financing. In connection with the issuance of the Notes to the Investors, the Company also issued to the Investors warrants to purchase an aggregate of 5,000,000 shares of the Company's Common Stock at an exercise price of $0.05 per share. The warrants are exercisable for a period of three years. The Company may use any funds received from the Investors to make payments on the Company's existing indebtedness and accrued interest on that indebtedness, for working capital and general corporate purposes, in each case in the ordinary course of business, and to pay fees and expenses in connection with the Company's entry into the Purchase Agreement.
