*On October 4, 2023, the Issuer closed an offering of 15,010,810 shares of Common Stock with accompanying common warrants to purchase up to 9,294,022 shares of Common Stock (or pre-funded warrants to purchase up to 9,294,022 shares of Common Stock in lieu thereof) (the “Tranche 1 Warrants”) and accompanying common warrants to purchase up to 11,265,086 shares of Common Stock (or pre-funded warrants to purchase up to 11,265,086 shares of Common Stock in lieu thereof) (the “Tranche 2 Warrants”). In lieu of shares of Common Stock, the Issuer offered pre-funded warrants to purchase up to 3,577,240 shares of Common Stock (the “Pre-Funded Warrants”) with accompanying Tranche 1 Warrants and accompanying Tranche 2 Warrants. As a result of the offering and certain ownership limitations described below, the Firm’s beneficial ownership in the Issuer is currently limited to 9.99%.

 

The Tranche 1 Warrants are exercisable from the date of issuance and expire 60 days after the later of (i) the date on which the Issuer first publicly discloses, whether by press release or Form 8-K filing, the top-line data for its PALISADE-3 study and (ii) the date on which the Issuer first publicly discloses, whether by press release or Form 8-K filing, the top-line data for its PALISADE-4 study. The Tranche 1 Warrants contain an exercise limitation prohibiting Commodore Master from exercising the Tranche 1 Warrants until such time as the holder, together with certain related parties, would not beneficially own after any such exercise more than 9.99% of the then issued and outstanding Common Stock. Due to this blocker, the Tranche 1 Warrants owned by Commodore Master are not fully exercisable at this time. The blocker percentage may be increased up to 19.99% or decreased by Commodore Master upon 61 days’ notice to the Issuer.
