Peter S. Park ("Mr. Park") is the sole member and manager of the Reporting Person.

Section 240.16a-1(a)(2), the Reporting Person's and Mr. Park's beneficial ownership is limited to their pecuniary interest, if any, in such securities. ( 3 )On December 20, 2018, the PW Funds entered into a Purchase Agreement with the Company (the "Purchase Agreement"), pursuant to which the PW Funds agreed to purchase 15,000 shares of Series A Convertible Preferred Stock, par value $0.001 per share, for an aggregate purchase price of $15,000,000 (the "Private Placement"). The closing of the Private Placement is contingent on the Company obtaining stockholder approval of (i) an amendment to the Company's Amended and Restated Certificate of Incorporation to authorize 1,000,000 shares of "blank check" preferred stock and (ii) the issuance of more than 20% of the Common Stock in the Private Placement for purposes of Nasdaq Listing Rule 5635 (the "Stockholder Approval"). ( 4 )The warrants reported on this Form 4 (the "Commitment Warrants") are only exercisable to the extent that the Company does not obtain the Stockholder Approval by April 15, 2019 (the "Exercisability Date"). ( 5 )The Commitment Warrants expire on the tenth anniversary of the Exercisability Date and will be surrendered to the Company for cancellation if the Stockholder Approval is obtained on or prior to the Exercisability Date. ( 6 )The Company issued the Commitment Warrants at no additional cost, in consideration of the PW Funds' commitments pursuant to the Purchase Agreement. ( 7 )As of December 20, 2018, PWIMF held Commitment Warrants to purchase up to 452,135 shares of Common Stock and PWPI held Commitment Warrants to purchase up to 47,865 shares of Common Stock.
