As discussed with Ms. Kontulis, on November
12, 2019, Staff notified the Company that due to the failure of its common stock to demonstrate compliance with the minimum bid
price requirement, the common stock would be subject to delisting. On November 19, 2019, the Company requested an appeal, and is
scheduled to appear before a Nasdaq Hearings Panel (the "Panel") on December 12, 2019.
In light of the above, Staff has determined
that the Company's warrants no longer comply with Listing Rule 5560(a),1 since the underlying security, the common
stock, is subject to delisting. Accordingly, this matter serves as an additional basis for delisting the Company's securities
from The Nasdaq Stock Market.
This is formal notification that the Panel
will consider this matter in rendering a determination regarding the Company's continued listing on The Capital Market. Pursuant
to Listing Rule 5810(d), the Company should present its views with respect to this additional deficiency at its Panel hearing.
If the Company fails to address the aforementioned issue, the Panel will consider the record as presented at the hearing and will
make its determination based upon that information.
Listing Rule 5560(a) states that "For rights, warrants, and put warrants (that is, instruments that grant the holder the
right to sell to the issuing company a specified number of shares of the Company's common stock, at a specified price until a
specified period of time), the underlying security must remain listed on Nasdaq or be a Covered Security, and there must be at
least two registered and active Market Makers, one of which may be a Market Maker entering a stabilizing bid."
