Convertible Promissory Note

On August 15, 2022, the Company entered into a Securities Purchase Agreement (the “August Purchase Agreement”), by and between the Company and an institutional investor (the “Investor”), pursuant to which the Company agreed to issue to the Investor a senior secured convertible note in the principal amount of $3,600,000 (the “Convertible Note”) and a warrant (the “August Warrant”) to purchase up to 20,970 shares of the Company’s common stock, at an exercise price of $99.70 per share (the “Exercise Price”), in consideration for $3,000,000. Pursuant to the August Purchase Agreement, upon the closing of the private placement, pursuant to which Maxim Group LLC (“Maxim”) acted as the placement agent (the “Private Placement”), the Company received gross proceeds of $3,000,000. After the deduction of banker fees, commitment fees and other expenses associated with the transaction, the Company received net proceeds of $2,483,000. The Company used the net proceeds primarily for working capital and general corporate purposes.

The Convertible Note matures on August 15, 2024, does not bear interest and ranks senior to the Company’s existing and future indebtedness and is secured to the extent and as provided in the Security Agreements. The Convertible Note is convertible in whole or in part at the option of the Convertible Note Investor into shares of Common stock (the “Conversion Shares”) at the Conversion Price (as defined below) at any time following the date of issuance of the Convertible Note. The Convertible Note defines “Conversion Price” as equal to the lesser of (a) 90% of the average of the five lowest daily VWAPs (as defined in the Convertible Note) during the previous twenty trading days prior to delivery to the Company of the Convertible Note Investor’s applicable notice of conversion (the “Conversion Notice”) and(b) $92.60 (the “Base Conversion Price”). The Base Conversion Price is subject to full ratchet antidilution protection, subject to a floor conversion price of $0.50 per share (the “Floor Price”).

The obligations and performance of the Company under the Convertible Note and the August Purchase Agreement are secured by: (a) a senior lien granted pursuant to security agreements between the Convertible Note Investor and the Company, on (a) all of the assets of the Company (b) a senior lien granted pursuant to trademark security agreements between the Convertible Note Investor and the Company; (c) a senior lien granted pursuant to a patent security agreement between the Convertible Note Investor and the Company on all of the patent assets of the Company; and (d) a pledge of certain securities pursuant to a pledge agreement between the Convertible Note Investor, the Company (such agreements listed in (a)-(d) above, collectively, the “Security Agreements”). The payment and performance obligations of the Company under the Convertible Note and the August Purchase Agreement are guaranteed pursuant to a guaranty by the Company in favor of the Convertible Note Investor.

In connection with the Private Placement, the Company issued warrants to the Convertible Note Investor and Maxim to purchase common shares of 20,970 and 1,944, respectively (see Note 5 – Fair Value Measurements). The sum of the fair value of the warrants, the original issue discount for interest, issuance costs and the derivative liability for the embedded conversion feature for the August 2022 Notes were recorded as debt discounts totaling $2,509,000 to be amortized to interest expense over the respective term using the effective interest method. During the year ended December 31, 2023, the Company recognized $737,000 of interest expense from the amortization of debt discounts and repayment of the convertible note payable in April 2023.

In connection with the Private Placement, the Company entered into a placement agency agreement with Maxim (the “Placement Agency Agreement”), and agreed to issue to Maxim, a warrant to purchase up to an aggregate of 1,944 shares of Common Stock (the “Maxim Warrant”) at an exercise price of $99.70 per share, which is exercisable at any time on or after the six-month anniversary of the closing date of the Private Placement and will expire on the fifth (5^th) anniversary of its date of issuance.

Effective August 24, 2022, the Company and the Investor agreed to amend Section 3.1(b) of the Convertible Note to provide that the Conversion Price could not be lower than the Floor Price until stockholder approval has been obtained, after which stockholder approval the Floor Price may be reduced to no lower than $0.25, subject to adjustment pursuant to the terms of the August 2022 Note. The changes were effected by cancellation of the Convertible Note and the issuance of a replacement senior secured convertible note (the “New Convertible Note”) to the Investor. The New Convertible Note contains identical terms as the Convertible Note, except for the amendment to the Section 3.1(b).

On November 21, 2022, the Company and Maxim entered into an agreement to amend the Maxim Warrant (the “Maxim Warrant Amendment”). Specifically, the Maxim Warrant Amendment sets forth certain circumstances in which the lock up restrictions to which the Maxim Warrant is subject would not apply. The Maxim Warrant Amendment also clarifies certain limitations with respect to demand registration rights and provides that Maxim’s piggy-back registration rights expire on the fifth (5th) anniversary of the Maxim Warrant’s date of issuance.

The New Convertible Note contains several embedded conversion features. The Company concluded that those conversion features require bifurcation from the New Convertible Note and subsequent accounting in the same manner as a freestanding derivative. The Company recognized a derivative liability of $286,000 upon execution of the note agreement and such amount was included in the $2,509,000 of debt discounts noted above. Subsequent changes in the fair value of these conversion features are measured at each reporting period and recognized in the consolidated statement of operations.

On November 28, 2022, the Company entered into a waiver of rights (the “Waiver”) with the Convertible Note Investor, pursuant to which the Convertible Note Investor agreed to waive certain prohibitions under the August Purchase Agreement with respect to the offering of units in December 2022 in exchange for the issuance by the Company, on the closing date of such offering, of an additional number of Series A Warrants and an additional number of Series B Warrants equal to the quotient obtained by dividing $750,000 by the public offering price for the units sold in the offering (such Warrants, the “Waiver Warrants”).

In connection with the public offering the Company consummated on December 1, 2022 (the “December 2022 Offering”), the Company issued 53,572 Series A Warrants and 53,572 Series B Warrants to the Convertible Note Investor (See Note 6). The Company’s obligation to issue shares of common stock underlying the Waiver Warrants is expressly conditioned upon stockholder approval of all of the transactions contemplated by the August Purchase Agreement. At a Special Meeting of Stockholders held on January 24, 2023, the Company received stockholder approval of the transactions contemplated by the August Purchase Agreement. Additionally, as a result of the December 2022 Offering, the Base Conversion Price was adjusted to the Floor Price.

On February 1, 2023, the holder of the Convertible Note converted approximately $708,000, a portion of the outstanding principal amount into 67,500 shares of the Company’s common stock.

On April 11, 2023, the Company paid $1,656,744 to the holder of the Convertible Note which repaid the entirety of the outstanding balance and included the unpaid principal, interest through the payoff date, and a pre-payment premium of $276,000 which was recorded as a component of loss on debt extinguishment.
