WARRANT

 

THIS
CERTIFIES THAT, for value received

 

is
the registered holder of a warrant or warrants (the “Warrant(s)”) to purchase one fully paid and non-assessable share
of Class A Common Stock, par value $0.0001 per share (“Shares”), of Forum Merger Corporation, a Delaware corporation
(the “Company”), expiring at 5:00 p.m., New York City time, on the five year anniversary (the “Expiration Date”)
of the completion by the Company of a merger, share exchange, asset acquisition, stock purchase, recapitalization, reorganization
or other similar business combination with one or more businesses or entities (a “Business Combination”). The Warrant
entitles the holder thereof to purchase from the Company, commencing on the later of (i) 30 days after the Company’s completion
of a Business Combination and (ii)                     ,
2018, such number of Shares of the Company at the price of $11.50 per share, upon surrender of this Warrant Certificate and payment
of the Warrant Price at the office or agency of the Warrant Agent, Continental Stock Transfer & Trust Company, but only subject
to the conditions set forth herein and in the Warrant Agreement between the Company and Continental Stock Transfer & Trust
Company. In no event will the Company be required to net cash settle the warrant exercise. The Warrant Agreement provides that
upon the occurrence of certain events the Warrant Price and the number of Warrant Shares purchasable hereunder, set forth on the
face hereof, may, subject to certain conditions, be adjusted. The term Warrant Price as used in this Warrant Certificate refers
to the price per Share at which Shares may be purchased at the time the Warrant is exercised.

 

No
fraction of a Share will be issued upon any exercise of a Warrant. If the holder of a Warrant would be entitled to receive a fraction
of a Share upon any exercise of a Warrant, the Company shall, upon such exercise, round up to the nearest whole number the number
of Shares to be issued to such holder.

 

Upon
any exercise of the Warrant for less than the total number of full Shares provided for herein, there shall be issued to the registered
holder hereof or the registered holder’s assignee a new Warrant Certificate covering the number of Shares for which the
Warrant has not been exercised.

 

Warrant
Certificates, when surrendered at the office or agency of the Warrant Agent by the registered holder hereof in person or by 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 and evidencing in
the aggregate a like number of Warrants.

 

Upon
due presentment for registration of transfer of the Warrant Certificate at the office or agency 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 in exchange for this Warrant Certificate, subject to the limitations provided in the Warrant Agreement, without
charge except for any applicable tax or other governmental charge.

 

The
Company and the Warrant Agent may deem and treat the registered holder as the absolute owner 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 registered holder, and for all other purposes, and neither the Company nor the Warrant Agent shall be affected by any notice
to the contrary.

 

This
Warrant does not entitle the registered holder to any of the rights of a stockholder of the Company.

 

The
Company reserves the right to call the Warrant at any time prior to its exercise, with a notice of call in writing to the holders
of record of the Warrant, giving 30 days’ notice of such call at any time after the Warrant becomes exercisable if the last
sale price of the Shares has been at least $18.00 per share on each of 20 trading days within any 30 trading day period ending
on the third business day prior to the date on which notice of such call is given, if, and only if, there is a current registration
statement in effect with respect to the Shares underlying the Warrant. The call price of the Warrants is to be $0.01 per Warrant.
Any Warrant either not exercised or tendered back to the Company by the end of the date specified in the notice of call shall
be canceled on the books of the Company and have no further value except for the $0.01 call price.
