To remain eligible for trading on the OTCQB marketplace, the Company must: "Have proprietary priced quotations published by a Market Maker in OTC Link with a minimum closing bid price of $0.01 per share on at least one of the prior thirty consecutive calendar days. In the event that the minimum closing bid price for the Company’s common stock falls below $0.01 per share, a grace period of 180 calendar days to regain compliance shall begin, during which the minimum closing bid price for the Company’s common stockmust be $0.01 or greater for ten consecutive trading days"
