during the period set forth in the Warrant Agreement referred to below, to receive from the Company that number of fully paid and

the same effect as though fully set forth at this place.

The Warrants evidenced by this Warrant Certificate
are part of a duly authorized issue of Warrants entitling the holder on exercise to receive                
shares of Common Stock and are issued or to be issued pursuant to a Warrant Agreement dated as of           ,
2019 (the “Warrant Agreement”), duly executed and delivered by the Company to American Stock Transfer &
Trust Company, LLC, a New York limited liability trust company, as warrant agent (the “Warrant Agent”),
which Warrant Agreement is hereby incorporated by reference in and made a part of this instrument and is hereby referred to for
a description of the rights, limitation of rights, obligations, duties and immunities thereunder of the Warrant Agent, the Company
and the holders (the words “holders” or “holder” meaning the Registered Holders
or Registered Holder) of the Warrants.  A copy of the Warrant Agreement may be obtained by the holder hereof upon written
request to the Company.  Defined terms used in this Warrant Certificate but not defined herein shall have the meanings given
to them in the Warrant Agreement.

 

Warrants may be exercised at any time during
the Exercise Period set forth in the Warrant Agreement.  The holder of Warrants evidenced by this Warrant Certificate may
exercise them by surrendering this Warrant Certificate, with the form of election to purchase set forth hereon properly completed
and executed, together with payment of the Exercise Price as specified in the Warrant Agreement (or through “cashless exercise”
as provided for in the Warrant Agreement) at the principal corporate trust office of the Warrant Agent.  In the event that
upon any exercise of Warrants evidenced hereby the number of Warrants exercised shall be less than the total number of Warrants
evidenced hereby, there shall be issued to the holder hereof or his, her or its assignee, a new Warrant Certificate evidencing
the number of Warrants not exercised.

 

Notwithstanding anything else in this Warrant
Certificate or the Warrant Agreement, no Warrant may be exercised unless at the time of exercise (i) a registration statement
covering the shares of Common Stock to be issued upon exercise is effective under the Securities Act and (ii) a prospectus
thereunder relating to the shares of Common Stock is current, except through “cashless exercise” as provided for in
the Warrant Agreement.

 

The Warrant Agreement provides that upon
the occurrence of certain events the number of shares of Common Stock issuable upon exercise of the Warrants set forth on the face
hereof may, subject to certain conditions, be adjusted.  If, upon exercise of a Warrant, the holder thereof would be entitled
to receive a fractional interest in a share of Common Stock, the Company shall, upon exercise, round down to the nearest whole
number of shares of Common Stock to be issued to the holder of the Warrant.

 

Warrant Certificates, when surrendered at
the principal corporate trust office of the Warrant Agent by the Registered Holder thereof in person or by legal representative
or attorney duly authorized in writing, may be exchanged, in the manner and subject to the limitations provided in the Warrant
Agreement, but without payment of any service charge, for another Warrant Certificate or Warrant Certificates of like tenor evidencing
in the aggregate a like number of Warrants.

 

Upon due presentation for registration of
transfer of this Warrant Certificate at the office of the Warrant Agent a new Warrant Certificate or Warrant Certificates of like
tenor and evidencing in the aggregate a like number of Warrants shall be issued to the transferee(s) in exchange for this
Warrant Certificate, subject to the limitations provided in the Warrant Agreement, without charge except for any tax or other governmental
charge imposed in connection therewith.

 

The Company and the Warrant Agent may deem
and treat the Registered Holder(s) hereof as the absolute owner(s) of this Warrant Certificate (notwithstanding any notation
of ownership or other writing hereon made by anyone), for the purpose of any exercise hereof, of any distribution to the holder(s) hereof,
and for all other purposes, and neither the Company nor the Warrant Agent shall be affected by any notice to the contrary. 
Neither the Warrants nor this Warrant Certificate entitles any holder hereof to any rights of a stockholder of the Company.

In the event that the Warrant is a Private
Placement Warrant that is to be exercised on a “cashless” basis pursuant to  Section 3.03(a)(iii) of the Warrant
Agreement, the number of shares of Common Stock that this Warrant is exercisable for shall be determined in accordance with Section 3.03(a)(iii) of the Warrant Agreement.

exercised on a “cashless” basis pursuant to Section 7.04 of the Warrant Agreement, the number of shares of Common
Stock that this Warrant is exercisable for shall be determined in accordance with Section 7.04 of the Warrant Agreement.

Warrant is exercisable for would be determined in accordance with the relevant section of the Warrant Agreement which allows for
such cashless exercise and (ii) the holder hereof shall complete the following: The undersigned hereby irrevocably elects

Warrant Certificate be delivered to                ,
