three accredited investors, two of whom were current members of the Board of Directors of the Company (collectively the &ldquo;Investors&rdquo;),
pursuant to which the Company issued and sold unsecured convertible promissory notes (the &ldquo;Notes&rdquo;) to the Investors
in the aggregate principal amount of $350,000. The Company may issue additional Notes in the future, up to an aggregate of $2,500,000

Notes are due on November 6, 2023 (the &ldquo;Maturity Date&rdquo;) and accrue simple interest at an annual rate of 6% on the
aggregate unconverted and outstanding principal amount, payable annually, beginning October 31, 2020. The Company will pay (a
&ldquo;PIK Payment&rdquo;) the interest due by adding such interest (including interest at the Default Rate, as defined below,
if any) to the then-outstanding principal amount of the Notes on each interest payment date and on the Maturity Date. Each PIK
Payment will be preceded by written notice from the Company to the Note holder setting forth in reasonable detail the amount of
such PIK Payment and the principal amount of the Note following such PIK Payment. The Notes will bear interest at the rate of
12% per year (the &ldquo;Default Rate&rdquo;) following a default.</FONT></P>

days (whether or not consecutive) during any 30 consecutive trading day period ending on, and including, the trading day immediately
