The March Offering caused a Triggering Event as defined in the Unterberg Warrant Agreement, and the warrants were repriced from an exercise price of $2.14 to $2.07. The Triggering Event charges of $11 thousand were recorded to Stockholders’ Equity during the first quarter of 2018. In connection with the Company’s September 2017 offering of Series B Preferred Stock (the “Series B Transaction”) to certain investors (the “Series B Stockholders”), the Company entered into a Registration Rights Agreement with investors (the “Series B Registration Rights Agreement”) under which the Company agreed to prepare and file a registration statement with the SEC within 30 days after closing of the Series B Transaction for the purpose of registering the resale of shares of common stock issuable upon conversion of the Series B Preferred Stock (the “Conversion Shares”). The Company agreed to use its reasonable best efforts to cause such resale registration statement to be declared effective by the SEC within 90 days after the closing of the Series B Transaction (120 days in the event the registration statement is reviewed by the SEC) and agreed to pay liquidated damages to the Series B Stockholders if such resale registration statement were not to become effective within the applicable time period. The Conversion Shares were included in the registration statement filed in connection with the March Offering, and such registration statement became effective on April 19, 2018, which was later than the deadline specified in the Series B Registration Rights Agreement, resulting in liquidated damage payments of $48 thousand to Series B Stockholders. Certain Series B Stockholders, including without limitation, Smith and Arno, waived their rights to receive such liquidated damage payments.
