Inc., a Delaware corporation (the “Company”), at a purchase price per share of [            ] Dollars and [          ] cents ($[           ]) (the “Warrant
Price”), [________________(________)] shares of its Common Stock, par value $0.0001 per share (the “Common Stock”).
The number of shares purchasable upon exercise of the Common Stock Purchase Warrants (the “Warrants”) and the Warrant Price

prior to 5:00 p.m., New York time, on the third anniversary of the original issue date hereof (the “Expiration Date”) shall
thereafter be void.

 

Subject
to restriction specified in the Warrant Agreement, Warrants may be exercised in whole or in part on or after the date hereof by presentation
of this Warrant Certificate with the Exercise Notice on the reverse side hereof duly executed, and simultaneous payment of the Warrant
Price (or as otherwise set forth in Section 6.4 of the Warrant Agreement) at the principal office of the Company (or if a warrant agent
is appointed, at the principal office of the warrant agent). Payment of the Warrant Price shall be made by bank wire transfer to the
account of the Company
or by bank cashier’s check as provided in Section 3.1 of the Warrant Agreement. As provided in the Warrant Agreement, the Warrant
Price and the number or kind of shares which may be purchased upon the exercise of the Warrant evidenced by this Warrant Certificate
are, upon the happening of certain events, subject to modification and adjustment.

 

    	 

     

    

 

This
Warrant Certificate is issued under and in accordance with a Warrant Agreement dated as of February 14, 2022 (the “Warrant Agreement”),
and is subject to the terms and provisions contained in the Warrant Agreement, to all of which the Holder of this Warrant Certificate
by acceptance of this Warrant Certificate consents. A copy of the Warrant Agreement may be obtained by the Holder hereof upon written
request to the Company.

 

Upon
any partial exercise of the Warrant evidenced by this Warrant Certificate, there shall be issued to the Holder hereof a new Warrant Certificate
in respect of the shares of Common Stock as to which the Warrant evidenced by this Warrant Certificate shall not have been exercised
to the extent provided in the Warrant Agreement. This Warrant Certificate may be exchanged at the office of the Company (or the warrant
agent, if appointed) by surrender of this Warrant Certificate properly endorsed either separately or in combination with one or more
other Warrant Certificates for one or more new Warrant Certificates evidencing the right of the Holder thereof to purchase the aggregate
number of shares as were purchasable on exercise of the Warrants evidenced by the Warrant Certificate or Certificates exchanged. No fractional
shares will be issued upon the exercise of any Warrant, but the Company will pay the cash value thereof determined as provided in the
Warrant Agreement. This Warrant Certificate is transferable at the office of the Company (or the warrant agent, if appointed) in the
manner and subject to the limitations set forth in the Warrant Agreement.

 

The
Holder hereof may be treated by the Company, the warrant agent (if appointed), and all other persons dealing with this Warrant Certificate
as the absolute owner hereof for any purpose and as the person entitled to exercise the rights represented hereby, or to the transfer
hereof on the books of the Company, any notice to the contrary notwithstanding, and until such transfer on such books, the Company (and
the warrant agent, if appointed) may treat the Holder hereof as the owner for all purposes.

 

Neither
the Warrant nor this Warrant Certificate entitles any Holder to any of the rights of a stockholder of the Company.
