Consideration

Subject to the terms and conditions set forth in the Merger Agreement, in consideration of the Merger, membership interests in Car Tech (the “Car Tech Units”) will be converted into the right to receive for each Car Tech Unit owned a number of shares of AltEnergy’s common stock (the “Parent Common Stock”) obtained by dividing (i) a fraction equal to (a) the quotient of (x) the Aggregate Merger Consideration divided by (y) ten dollars ($10.00), by (ii) the number of Car Tech Units that are issued and outstanding immediately prior to the effective time of the Merger.

“Aggregate Merger Consideration” means (I) $80,000,000 minus the amount of any shortfall in AltEnergy’s obligation to source at least $50,000,000 in proceeds from a private placement to be consummated immediately prior to the Merger, and an additional (II) $40,000,000 (the “Earn Out Consideration”).

Pursuant to the Lock-up Agreements, the Lock-up Holders will agree, among other things, that the Restricted Securities (as defined in the Lock-up Agreements), held following consummation of the Merger shall be subject to a lock-up restriction that will terminate with respect to (i) 50% of such shares on the 12 month anniversary of the closing date, (ii) 25% of such shares on the 18 month anniversary of the closing date, and (iii) 25% of such shares on the 24 month anniversary of the closing date.

Under the terms of the Lock-up Agreement, upon completion of the Merger, 4,000,000 shares of Parent Common Stock to be held by the Sponsor (the “Sponsor Earn Out Shares”) and 4,000,000 of the Restricted Securities designated as Earn Out Shares under the Merger Agreement to be held by holders of Car Tech Units (the “Company Member Earn Out Shares”; and together with the Sponsor Earn Out Shares, the “Earn Out Shares”) will be subject to additional transfer restrictions, release and forfeiture terms. A block of fifty percent (50%) of the Earn Out Shares (2,000,000 shares of Parent Common Stock held by each of Sponsor and 2,000,000 shares of Parent Common Stock held by holders of Car Tech Units) (the “Block A Earn Out Shares,” of which 1,850,000 held by each are designated as Block A-1 Earn Out Shares and the balance are designated as Block A-2 Earn Out Shares) may not be transferred unless and until either (i) the closing price of shares of Parent Common Stock on the principal securities exchange or securities market on which the Parent Common Stock is then traded equals or exceeds $14.00 per share for any 20 trading days within any consecutive 30-trading day period during the Earn Out Period (as defined below) or (ii) immediately prior to the consummation of a Block A Change of Control (as defined below) during the Earn Out Period (each of clauses (i) and (ii), a “Block A Triggering Event”).
