Mr. Hoge's stock options exercisable for 500 shares of common stock of the issuer within 60 days were issued as compensation for Mr. Hoge's service as a director of the issuer. Mr. Hoge acquired the 270,373 shares of common stock of the issuer using his personal funds. The 30,000 shares of common stock issuable upon the exercise of warrants held by the Brett Widney Hoge Revocable Trust dated July 7, 2014 within 60 days and the 20,000 shares of common stock issuable upon the exercise of warrants held by RGH & BRH LLC within 60 days were acquired from the issuer in a private placement, pursuant to which on March 16, 2026, the issuer sold unsecured promissory notes in an aggregate principal amount of $500,000 and common stock warrants to purchase up to an aggregate of 50,000 shares of common stock, at an exercise price of $1.75 per share to the reporting persons (the "Private Placement"). The convertible notes mature 18 months from the date of issuance (the "Maturity Date") and accrue interest at an annual rate of 10% per annum with such interest paid in kind. The convertible notes are convertible into shares of common stock (the "Conversion Shares") at the option of the purchasers. The outstanding principal balance and unpaid accrued interest of the convertible notes on or during the 60 days prior to the Maturity Date, effective on the Maturity Date, convert into Conversion Shares at the conversion price of $1.60 per share of common stock, subject to adjustments from time to time (the "Conversion Price"), with the number of Conversion Shares to be determined by dividing the outstanding principal balance and unpaid accrued interest that is being converted by the Conversion Price (rounded to the nearest whole share so that no fractional shares are issuable). In the event the issuer's common stock closes at or above $3.00 per share for 10 consecutive trading days on or before the Maturity Date, the issuer may, in its sole discretion, elect to convert in whole upon 10 calendar days' written notice to the holders, the convertible notes into Conversion Shares at the Conversion Price. Upon the occurrence of a change of control prior to the conversion or repayment of the convertible notes, the holders shall have the option, exercisable by written notice to the issuer prior to the closing of such change of control, to have the outstanding principal and unpaid accrued interest repaid in full following such closing or convert the outstanding principal balance and unpaid accrued interest into common stock at the Conversion Price. These securities were acquired in the Private Placement using working capital of the Brett Widney Hoge Revocable Trust dated July 7, 2014 and RGH & BRH LLC.
