WARRANT

 

THIS CERTIFIES THAT, for value received  

 

is the registered holder of a warrant
or warrants (the “Warrant”), expiring at 5:00 p.m., New York City time, on the five year anniversary of the completion
by DT Asia Investments Limited, a British Virgin Islands company (the “Company”), of an initial merger, share exchange,
asset acquisition, share purchase, recapitalization, reorganization, contractual arrangements, or other similar business combination
with one or more businesses or entities (a “Business Combination”), to purchase one half (1/2) of 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) __________ __, 2015 [one year
from the date of the final prospectus] and (b) the Company’s completion of a Business Combination, such whole number of Shares
of the Company at the price of $12.00 per whole 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 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.

 

No fraction
of a Share will be issued upon any exercise of a Warrant.  A warrantholder may exercise its warrants only for a whole
number of shares.  This means that only an even number of warrants may be exercised at any given time by a warrantholder.

 

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.

 

    	1

    	 

    

 

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 for each day of the
30-day trading period and continuing each day thereafter until the date of redemption.  The call price of the Warrants
is to be $.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 $.01 call price.
