[1] On April 18, 2010, we entered into a securities purchase agreement with purchasers named therein to raise in the aggregate of approximately $3 million in a private placement of common stock and warrants pursuant to Section 4(2) of the Securities Act of 1933, as amended, and/or Regulation D promulgated thereunder. Upon closing of the transaction, we entered into a registration rights agreement with the buyers and issued to the buyers an aggregate of 571,429 shares of common stock at a per share price of $5.25, and warrants to acquire additional shares of common stock of up to fifty (50%) percent of the common shares acquired by each respective buyer at an exercise price of $6.00 per share.

[2] Gains for the period ended December 31, 2012 related to the revaluation of equity based liabilities. The gains related to the warrant liability portion were calculated from the date of the warrant issuance (April 18, 2010) through December 31, 2012. These gains and losses are reflected in our consolidated statements of operations as a component of other income (expense).
