The offering was upsized from $6.0 Million. The offering consists of 28,000,000 Common Units or Pre-funded Units, each consisting of one share of common stock (“Common Share”) or Pre-Funded Warrant, one half of a Class B-1 Warrant to purchase one Common Share at an exercise price of $0.375 per share (or 150% of the price of each Common Unit sold in the offering) or pursuant to an alternative cashless exercise option, which warrant will expire on the five-year anniversary of the original issuance date (the "Class B-1 Warrants") and one Class B-2 Warrant to purchase one Common Share at an exercise price of $0.425 per share (or 170% of the price of each Common Unit sold in the offering) which warrant will expire on the five-year anniversary of the original issuance date (the "Class B-2 Warrants" and together with the Class B-1 Warrants, the "Warrants").

The Pre-Funded Warrants will be immediately exercisable and may be exercised at any time until all of the Pre-Funded Warrants are exercised in full.
