Debt instrument description     The Company may sell additional notes to EEME Energy, provided that the aggregate amount does not exceed $7,500,000, and the convertible notes can only be issued for up to one year from the Initial Closing. In connection with the execution of the note purchase agreement, the Company agreed to pay 750,000 shares of the Company’s Class A common stock as an arrangement fee and 200,000 of the Company’s Class A common stock as an advisory fee, which is payable at the Initial Closing (collectively, the “Fee Shares to related party”). At issuance the Company recorded $1,425,000 in expenses for the Fee Shares to related party. This expense was recorded in general and administrative expenses in the consolidated statements of operations. EEME Energy has elected to convert an aggregate of $6,000,000 of the Convertible Promissory Note (including any interest accrued thereon) into shares of Class A common stock of New XCF. The Company has elected the fair value option for valuing this note payable to related party (the “EMEE Energy Note”).
