Warrants issued, description											the Company issued a warrant (the “Antara Warrant 2020”) to Antara Capital to purchase 3,650,000 shares (the “Antara Warrant Shares 2020”) of the Company’s common stock at an exercise price of $2.50 per share, subject to adjustment for certain distributions, stock splits, and issuances of common stock, as an incentive. The issuance of this warrant results in an additional debt discount that is amortized to interest expense over the term of the debt using the effective interest method. The Antara Warrant 2020 is exercisable for ten years from the date of issuance. If the fair market value of the Antara Warrant Shares 2020 is greater than $2.50 at the end of the exercise period, then the Antara Warrant 2020 will be deemed to be exercised automatically and immediately prior to the end of the exercise period. Pursuant to the Antara Warrant 2020, the Company granted Antara Capital preemptive rights to purchase its pro rata share, determined based on the number of shares held by Antara Capital or into which warrants held by Antara Capital (including the Antara Warrant 2020) are exercisable, of capital stock issued by the Company after the issuance date of the Antara Warrant 2020, subject to certain excepted issuances.
