[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).

- Definition This element represents the portion of the balance sheet assertion valued at fair value by the entity whether such amount is presented as a separate caption or as a parenthetical disclosure. Additionally, this element may be used in connection with the fair value disclosures required in the footnote disclosures to the financial statements. The element may be used in both the balance sheet and disclosure in the same submission. This item includes currency on hand as well as demand deposits with banks or financial institutions. It also includes other kinds of accounts that have the general characteristics of demand deposits in that the Company may deposit additional funds at any time and also effectively may withdraw funds at any time without prior notice or penalty. Cash equivalents, excluding items classified as marketable securities, include short-term, highly liquid investments that are both readily convertible to known amounts of cash, and so near their maturity that they present minimal risk of changes in value because of changes in interest rates. Generally, only investments with original maturities of three months or less qualify under that definition. Original maturity means original maturity to the entity holding the investment. For example, both a three-month US Treasury bill and a three-year Treasury note purchased three months from maturity qualify as cash equivalents. However, a Treasury note purchased three years ago does not become a cash equivalent when its remaining maturity is three months. + References Reference 1: http://www.xbrl.org/2003/role/presentationRef -Publisher FASB -Name Statement of Financial Accounting Standard (FAS) -Number 95 -Paragraph 8 -Footnote 2 -LegacyDoc This reference is SUPERSEDED by the Accounting Standards Codification effective for interim and annual periods ending after September 15, 2009.
