                 Reflects (i) 264,346 shares of the Issuer’s common stock, par value $0.0001 per share (“Common Stock”), held directly by Mr. Seldin, (ii) 121,411 shares of the Issuer’s Series A Preferred Stock, par value
                  $0.0001 per share (“Preferred Stock”), held directly by Mr. Seldin, assuming such shares of Preferred Stock have been converted into Common Stock at a Preferred Conversion Price (as defined below) equal to $10.00 divided by $5.00,
                  which represents the maximum number of shares issuable to holders of Preferred Stock (the “Maximum Preferred Conversion Ratio”) and (iii) 1,744,186 shares of Common Stock issuable to Mr. Seldin upon conversion of the 7% convertible
                  promissory notes due 2026 (the “Convertible Notes”) issued pursuant to that certain Note and Warrant Purchase Agreement, dated as of June 12, 2023, by and among the Issuer and the investors listed on Schedule I thereto (the “Purchase
                    Agreement”). The Preferred Stock is convertible at any time into Common Stock at a conversion rate equal to $10.00 (subject to equitable adjustment in the event of a stock split, stock consolidation, subdivision or certain other
                  events of a similar nature that increase or decrease the number of shares of Preferred Stock outstanding) divided by the lesser of (i) $11.50 and (ii) the greater of (x) 115% of the lowest volume weighted average price per share of Common
                  Stock as displayed under the heading Bloomberg VWAP (the “VWAP”) for any consecutive ninety-trading day period prior to the calculation of such VWAP and (y) $5.00, in each case subject to adjustment as set forth in the Certificate
                  of Designations of Series A Preferred Stock (the “Preferred Conversion Price”). The Convertible Notes and any accrued interest thereon are convertible at the option of the holder at any time following June 23, 2023 prior to
                  repayment of the Convertible Notes into shares of Common Stock at a conversion price of $0.688 (subject to adjustment pursuant to the terms of the Convertible Notes, the “Convertible Note Conversion Price”). Interest accrues on the
                  unpaid principal amount of the Convertible Notes at a rate equal to 7% per annum, but it is not due and payable until the maturity date.
