 [Form of Warrant Certificate] 

[Reverse] 
 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            , 2018 (the “Warrant Agreement”), duly executed and delivered by the Company to
Continental Stock Transfer & Trust Company, a New York corporation, 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 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 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. 

  
 3 








 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.

to                whose address is                    . If said

of                    , whose address

 In the event
the Warrant has been called for redemption by the Company pursuant to Section 6 of the Warrant Agreement and the Company has required cashless exercise pursuant to Section 6.3 of the Warrant
Agreement, the number of shares of Common Stock this Warrant is exercisable for shall be determined in accordance with subsection 3.3.1(b) and Section 6.3 of the Warrant Agreement. 

In the event the Warrant is a Private Placement Warrant or an Forward Purchase Warrant to be exercised on a “cashless” basis
pursuant to subsection 3.3.1(c) of the Warrant Agreement, the number of shares of Common Stock this Warrant is exercisable for shall be determined in accordance with subsection 3.3.1(c) of the Warrant Agreement. 

In the event the Warrant is to be exercised on a “cashless” basis pursuant to Section 7.4 of the Warrant
Agreement, the number of shares of Common Stock this Warrant is exercisable for shall be determined in accordance with Section 7.4 of the Warrant Agreement. 

In the event the Warrant may be exercised, to the extent allowed by the Warrant Agreement, through cashless exercise (i) the number of
shares of Common Stock this 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 to exercise the right, represented by this Warrant Certificate, through the cashless exercise provisions of the Warrant Agreement, to receive shares of Common Stock. If said number of shares is less than all of
the shares of Common Stock purchasable hereunder (after giving effect to the cashless exercise), the undersigned requests a new Warrant Certificate representing the remaining balance of such shares of Common Stock be registered in the name
of                    , whose address
is                    and such Warrant Certificate be delivered
to                    , whose address
is                    .
