WARRANT


 


THIS WARRANT CERTIFIES THAT, for value
received                                         ,
or registered agents, is the registered holder of a Warrant or Warrants expiring on a date which is five (5) years from the closing
date (the “Warrant”) of the Company’s initial public offering (the “Offering”), to purchase one fully paid and non-assessable share (the “Warrant Shares”), of common stock, par value $0.001 per share (the
“Common Stock”), of M I ACQUISITIONS, INC., a Delaware corporation (the “Company”), for each Warrant evidenced
by this Warrant Certificate. This Warrant Certificate is subject to and shall be interpreted under the terms and conditions of
the Warrant Agreement (as defined below).


 


The Warrant entitles
the holder thereof to purchase from the Company, from time to time, in whole or in part, commencing on the later to occur of (i)
30 days following the completion of the Company’s initial business combination and (ii) twelve (12) months following the
closing of the Public Offering, such number of Warrant Shares at the price of $12.00 per share (the “Warrant Price”),
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”), such payment to be made subject to the conditions set forth herein and in
the Warrant Agreement, dated [            ], 2016, between the Company
and the Warrant Agent (the “Warrant Agreement”). In no event shall the registered holder(s) of this Warrant be entitled
to receive a net-cash settlement in lieu of physical settlement in Warrant Shares of the Company. 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 be adjusted, subject to certain conditions. The term Warrant Price as used in this Warrant Certificate
refers to the price per Warrant Share at which Warrant Shares may be purchased at the time the Warrant is exercised.


 


This Warrant will
expire on the date first referenced above if it is not exercised prior to such date by the registered holder pursuant to the terms
of the Warrant Agreement or if it is not redeemed by the Company prior to such date.


 


No fraction of
a Share will be issued upon any exercise of a Warrant. If, upon exercise of a Warrant, a holder would be entitled to receive a
fractional interest in a Share, the Company will, upon exercise, issue or cause to be issued only the largest whole number of Warrant
Shares issuable on such exercise (and such fraction of a Share will be disregarded).


 


Upon any exercise
of the Warrant for less than the total number of full Warrant Shares provided for herein, there shall be issued to the registered
holder(s) hereof or its assignee(s) a new Warrant Certificate covering the number of Warrant 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(s) 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(s)
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(s) 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 registered holder(s), 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(s) to any of the rights of a stockholder of the Company.


 


After the Warrant
becomes exercisable and prior to its expiration date, the Company reserves the right to call the Warrant at any time, with a notice
of call in writing to the holder(s) of record of the Warrant, giving 30 days’ notice of such call if the last reported sale
price of the Warrant Shares has been equal to or greater than $16.00 per share of the Warrant Price for any 20 trading days within
a 30 consecutive trading day period ending on the third business day prior to the date on which notice of such call is given, provided
that (i) a registration statement under the Act with respect to the shares of Common Stock issuable upon exercise must be effective
and a current prospectus must be available for use by the registered holders hereof or (ii) the Warrants may be exercised on cashless
basis as set forth in the Warrant Agreement and such cashless exercise is exempt from registration under the Securities Act of
1933, as amended. The call price is $0.01 per Warrant Share.


 


If the foregoing
conditions are satisfied and the Company calls the Warrant for redemption, each holder will then be entitled to exercise his, her
or its Warrant prior to the date scheduled for redemption; provided that the Company may require the Registered Holder who desires
to exercise the Warrant, to elect cashless exercise as set forth in the Warrant Agreement, and such Registered Holder must exercise
the Warrants on a cashless basis if the Company so requires. 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.
