 of $2.00 per share of any of the October 2025 Warrants exercised for cash and $2.50 per share of any Placement Agent
Warrants exercised for cash. Additionally, we will pay the expenses, other than underwriting discounts and commissions and expenses incurred
by the Selling Securityholders for brokerage, accounting, tax or legal services or any other expenses incurred by the Selling Securityholders
in disposing of the securities, associated with the sale of securities pursuant to this prospectus. Additional details regarding the securities
to which this prospectus relates and the Selling Securityholders is set forth in this prospectus in the Prospectus Summary under the heading
“Registered Direct Offering and Concurrent Private Placement” and “Description of Securities.”

We are registering the securities
for resale pursuant to the Selling Securityholders’ registration rights under certain agreements between us and the Selling Securityholders.
Our registration of the securities covered by this prospectus does not mean that the Selling Securityholders will offer or sell any of
the shares of Class A Common Stock. The Selling Securityholders may offer, sell, or distribute all or a portion of their shares of Class
A Common Stock publicly or through private transactions at prevailing market prices or at negotiated prices. We will not receive any proceeds
from the sale of shares of Class A Common Stock by the Selling Securityholders pursuant to this prospectus. We provide more information
about how the Selling Securityholders may sell the shares in the section entitled “Plan of Distribution.”

Sales of a substantial number
of shares of Class A Common Stock in the public market, including the resale of the shares of Class A Common Stock held by our stockholders
pursuant to this prospectus or pursuant to Rule 144, could occur at any time. These sales, or the perception in the market that the holders
of a large number of shares of Class A Common Stock intend to sell shares, could reduce the market price of the Class A Common Stock and
make it more difficult for you to sell your holdings at times and prices that you determine are appropriate. We expect that, because there
is a large number of shares being registered pursuant to the registration statement of which this prospectus forms a part, the Selling
Securityholders will continue to offer the securities covered thereby pursuant to this prospectus or pursuant to Rule 144 for a significant
period of time, the precise duration of which cannot be predicted. Accordingly, the adverse market and price pressures resulting from
an offering pursuant to the registration statement may continue for an extended period of time
