Explanation of Responses:
(1)  On April 7, 2020, upon the consummation of a private placement of the Issuer, Pillar Partners Foundation, L.P. ("Pillar Foundation"), acquired, in the Private Placement, 3,039,514 shares of common stock (the "Pillar Foundation Shares") as well as warrants to purchase 3,039,514 shares of common stock of the Issuer (the "Pillar Foundation Warrants"). Each Pillar Foundation Share and the associated Pillar Foundation Warrant had a combined purchase price of $1.645, which combined purchase price included $0.125 for each share of common stock underlying each Pillar Foundation Warrant. The exercise price of each Pillar Foundation Warrant is $2.28 per share, subject to adjustment pursuant to the terms of the Pillar Foundation Warrants and the Pillar Foundation Warrants expire 3 years from their issuance date.
(2)  The Pillar Foundation Warrants became exercisable on May 12, 2020 following receipt of shareholder approval for the sufficient increase in the Issuer's authorized shares of common stock to cover the exercise of the Pillar Foundation Warrants. The Pillar Foundation Warrants are exercisable, to the extent that after giving effect to such exercise the holders thereof and their affiliates would beneficially own, for purposes of Rule 13d-3 under the Securities Act of 1934, as amended, no more than 19.99% of the outstanding shares of Common Stock of the Issuer.

Youssef El Zein and Abude Umari are directors of Pillar GP. Each of Pillar GP, Mr. El Zein and Mr. Umari disclaims Section 16 beneficial ownership of the securities beneficially owned by the Pillar Funds and this report shall not be deemed an admission that any of Pillar GP, Mr. El Zein or Mr. Umari is the Section 16 beneficial owner of any such securities, except to the extent of its or his pecuniary interest therein, if any, by virtue of its or his ownership interest in the Pillar Funds or Pillar GP, as applicable.
