Check the appropriate box below if the Form 8-K filing is intended to simultaneously satisfy the filing obligation of the registrant under any of the following provisions (see General Instruction A.2):

Securities registered pursuant to Section 12(b) of the Act:

Indicate by check mark whether the registrant is an emerging growth company as defined in Rule 405 of the Securities Act of 1933 (17 CFR §230.405) or Rule 12b-2 of the Securities Exchange Act of 1934 (17 CFR §240.12b-2).

Emerging growth company ¨

If an emerging growth company, indicate by check mark if the registrant has elected not to use the extended transition period for complying with any new or revised financial accounting standards provided pursuant to Section 13(a) of the Exchange Act. ¨

On April 27, 2020, the Company made two short-term, secured bridge notes (the “Notes”) evidencing an aggregate of $350,000 of loans made to the Company by two parties: Cheval Holdings, Ltd., an affiliate of Black Horse Capital, L.P., the Company’s controlling stockholder, lent $100,000; and Nomis Bay LTD., the Company’s second largest shareholder, lent $250,000. The proceeds from the Notes will be used for working capital and general corporate purposes.

The Notes rank on par with the similar short-term, secured bridge notes made by the Company in June 2019, and possess other terms and conditions substantially consistent with those notes. The Notes bear interest at a rate of 7.0% per annum and will mature on December 31, 2020. The Notes may become due and payable at such earlier time as the Company raises more than $10,000,000 in a bona fide financing transaction or upon a change in control. The Notes also are secured by a lien of substantially all of the Company’s assets.

Upon an event of default, which events include, but are not limited to, (1) the Company failing to timely pay any monetary obligation under the Notes; (2) the Company failing to pay its debts generally as they become due and (3) the Company commencing any proceeding relating to the Company under any bankruptcy reorganization, arrangement, insolvency, readjustment of debt, dissolution or liquidation or similar laws of any jurisdiction now or hereafter in effect, the interest payable on the Notes increases to 10.0% per annum. Further, upon certain events of default, all payments and obligations due and owed under the Notes shall immediately become due and payable without demand and without notice to the Company.
