WARRANT

 

THIS
WARRANT CERTIFIES THAT, for value received , or registered agents, is the registered holder of a Warrant or Warrants (the “Warrant”),
expiring on a date which is five (5) years from the completion of the Company’s initial business combination, to purchase
one half of one fully paid and non-assessable ordinary share (the “Warrant Shares”), par value US$0.0001 per share
(the “Ordinary Shares”), of TKK SYMPHONY ACQUISITION CORPORATION , a Cayman Islands exempted company (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) the completion of the Company's initial business combination and (ii) twelve (12) months following the closing
of the Company’s initial public offering, such number of Warrant Shares at the price of US$5.75 per half 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 [●], 2018, 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. Only whole Ordinary Shares may be issued upon exercise of this Warrant.

 

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 shareholder 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 US$18.00 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 Ordinary Shares 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 United States Securities Act of 1933, as amended. The call price is US$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.

 

This
Warrant shall be governed and construed in accordance with the internal laws of the State of New York, without regard to conflicts
of laws principles thereof.
