	 	WARRANT	 

 

THIS CERTIFIES THAT, for value received

 

is the registered holder of a warrant or
warrants (the “Warrant(s)”) of DD3 Acquisition Corp., a British Virgin Islands company (the “Company”),
expiring at 5:00 p.m., New York City time, on the five year anniversary of the Company’s completion of an initial merger,
share exchange, asset acquisition, stock purchase, recapitalization, reorganization or other similar business combination with
one or more businesses or entities (a “Business Combination”), to purchase one fully paid and non-assessable
ordinary share, no par value (“Shares”), of the Company for each Warrant evidenced by this Warrant Certificate.
The Warrant entitles the holder thereof to purchase from the Company, commencing on the later of (a) ___________, 2019 and (b)
30 days after the Company’s completion of an initial Business Combination, such number of Shares of the Company at the Warrant
Price (as defined below), upon surrender of this Warrant Certificate and payment of the Warrant Price at the office or agency of
Continental Stock Transfer & Trust Company (the “Warrant Agent”), 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 any warrant exercise. The Warrant Agreement provides that upon the occurrence of certain
events the Warrant Price and the number of 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. The initial Warrant Price per Share is equal to $11.50
per share.

 

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 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 shareholder 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
at least 30 days’ notice of such call, at any time while the Warrant is 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 (the “30-day trading period”)
ending on the third business day prior to the date on which notice of such call is given and if, and only if, there is a current
registration statement in effect with respect to the Shares underlying the Warrants commencing five business days prior to the
30-day trading period and continuing each day thereafter until the date of redemption. 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.
