Amendment Description	The purpose of this Amendment No. 1 (this “Amendment”) on Form 10-Q/A is to amend and restate in their entirety the following items of our Quarterly Report on Form 10-Q for the period ended September 30, 2012 as originally filed with the Securities and Exchange Commission (the “SEC”) on November 14, 2012 (the “Original Form 10-Q”): (i) Item 1 of Part I “Financial Information”, (ii) Item 2 of Part I, “Management’s Discussion and Analysis of Financial Condition and Results of Operations”, and we have also updated the signature page and our financial statements formatted in Extensible Business Reporting Language (“XBRL”) in Exhibits 101. No other sections were affected, but for the convenience of the reader, this report on Form 10-Q/A restates in its entirety, as amended, our Original Form 10-Q. This report on Form 10-Q/A is presented as of the filing date of the Original Form 10-Q and does not reflect events occurring after that date, or modify or update disclosures in any way other than as required to reflect the restatement described below. We have determined that our previously reported results for the period ended September 30, 2012 erroneously included the cash consideration which represents the fair value of certain puttable warrant on the issuance date in additional paid in capital (“APIC”) rather than a derivative warrant liability. Additionally, the warrant liability was not recorded at fair value as of September 30, 2012, with changes in such fair value being recorded through other income (expenses) on our Unaudited Consolidated Statement of Operations. The Unaudited Consolidated Balance Sheets as of September 30, 2012 included in this Form 10-Q/A have been restated to remove the $2 million in cash consideration from APIC and reported a derivative warrant liability of $1.2 million. The Unaudited Consolidated Statements of Operations for the three months and nine months ended September 30, 2012 included in this Form 10-Q/A have been restated to include a loss of $63 thousand and a gain of $0.8 million, respectively, which represents the effect of change in the fair value of the derivative warrant liability. Certain adjustments have been made in the Unaudited Consolidated Statement of Stockholders’ Equity and Unaudited Consolidated Statements of Cash Flows to correspond to the income statement and balance sheet adjustments as described in Note 1 of the Notes to the Unaudited Consolidated Financial Statements included in this filing. In addition, we have made necessary conforming changes in “Management’s Discussion and Analysis of Financial Condition and Results of Operations” resulting from the correction of this error.
