Pursuant to a Securities Purchase Agreement , dated as of December 11, 2023, between the Issuer, Bios COF Fund and the other purchasers signatory thereto (the “Securities Purchase Agreement”), Bios COF Fund purchased from the Issuer in a private placement (the “Private Placement”) 574,241 units at a price of $1.22 per unit, each unit consisting of (i) one pre-funded warrant to purchase one share of Common Stock (the “Pre-Funded Warrants”), (ii) one Series A warrant to purchase one share of Common Stock (the “Series A Ordinary Warrants”) and (iii) one Series B warrant to purchase one share of Common Stock (the “Series B Ordinary Warrants” and together, the “Bios COF Warrants”).

The summary of the Securities Purchase Agreement contained herein is qualified in its entirety by reference to the full text of such agreement, a copy of which is filed as an exhibit hereto.

Warrants

Each Pre-Funded Warrant to be issued in the Private Placement will have an exercise price of $0.0001 per share, will be exercisable immediately and will be exercisable until the Pre-Funded Warrant is exercised in full. In lieu of making the cash payment otherwise contemplated to be made to the Issuer upon exercise of a Pre-Funded Warrant in payment of the aggregate exercise price, the holder may elect instead to receive upon such exercise (either in whole or in part) the net number of shares of Common Stock determined according to a formula set forth in the Pre-Funded Warrants.

The Series A Ordinary Warrants will be exercisable immediately and will expire 18 months from the date of issuance. The Issuer has the option to cause the Series A Ordinary Warrants to be exercised at a strike price of $1.25 per share upon the Issuer’s public announcement of INB-100 clinical data for the ten currently enrolled patients, should they remain alive and evaluable, covering a period of at least 11 months, along with certain stock price and trading volume requirements.

B-22

The Series B Ordinary Warrants will be exercisable immediately and will expire five years from the date of issuance. The Series B Ordinary Warrants allow the Company to redeem such warrants at a price of $0.01 per Series B Ordinary Warrant upon the Issuer’s public announcement of its INB-100 data for all enrolled patients covering a period of at least 22 months, along with certain stock price and trading volume requirements. Holders of Series B Ordinary Warrants may choose to exercise such warrants at a purchase price of $1.50 per share prior to such redemption.

The summary of the warrants contained herein is qualified in its entirety by reference to the full text of the Forms of Warrants, a copy of each of which is filed as an exhibit hereto.

Registration Rights Agreement

Also on December 11, 2023, Bios COF Fund entered into a registration rights agreement (the “Registration Rights Agreement”) with the Issuer and the other investors party thereto, pursuant to which the Issuer agreed to register for resale under the Securities Act of 1933, as amended, the Shares underlying the Bios COF Warrants.
