Term Loan, description		The Company with a "Tranche A" term loan facility of $800 ("Subordinated Loan Facility") of which $600 was advanced to the Company on April 8, 2020 and the balance of which is anticipated to be advanced to the Company within several days after such date. Interest will accrue on the Subordinated Loan Facility at the rate of 12% per annum, compounded and payable monthly, in-kind, by the automatic increase of the principal amount of the loan on each monthly interest payment date, by the amount of the accrued interest payable at that time ("PIK Interest"); provided, however, that at the option of the Company, it may pay interest in cash on any interest payment date, in lieu of PIK Interest. The Subordinated Lenders participating in the Tranche A term loan facility have the option of converting the principal balance of the loan held by each of them, in whole (unless otherwise agreed by the Company), into shares of the Company's common stock at a conversion price equal to the volume weighted average price of the Common Stock as reported by the NYSE American, during the five trading days preceding April 8, 2020 (the "Tranche A Conversion Price"). The conversion right is subject to stockholder approval as required by the rules of the NYSE American, and is expected to be obtained on June 11, 2020 at the Company's annual meeting of stockholders.	The Company entered into a certain Consent and Amendment to Loan Agreement and Loan Documents with Midcap (the "MidCap First Amendment"), which amended the MidCap Facility to, among other things, remove the existing $400 availability block, subject to the same being re-imposed at the rate of approximately $7 per month commencing June 1, 2020. The operative provisions relating to the removal of the availability block under the MidCap First Amendment became effective on April 8, 2020, following the consummation by the Company of the transactions contemplated by the Subordinated Loan Facility (defined below).
