Re:       Side Letter Concerning Warrant Agreement

Ladies and Gentlemen:

This letter agreement (“Agreement”) serves as written confirmation of the
agreement between Union Acquisition Corp., a Cayman Islands exempted company
(including successors and assigns pursuant to Section 9.1 of the Warrant
Agreement, the “Company”), and the undersigned with respect to certain changes
to the terms and conditions of the Private Warrants as set forth in that certain
warrant agreement dated as of February 27, 2018 (the “Warrant Agreement”), by
and between the Company and Continental Stock Transfer & Trust Company, a New
York corporation. Capitalized terms used but not otherwise defined herein shall
have the meanings given to such terms in the Warrant Agreement.

The parties hereto agree that:

1.      

The Private Warrants held by the undersigned and/or their Permitted Transferees
may be redeemed, at the option of the Company, at any time during the Exercise
Period (so long as there is a current registration statement in effect with
respect to the Ordinary Shares underlying the Warrants pursuant to Section 7.4
of the Warrant Agreement), at the office of the Warrant Agent, upon the notice
provided pursuant to Section 6.2 of the Warrant Agreement, at the price of $0.01
per Warrant (“Redemption Price”), provided that the last sales price of the
Ordinary Shares has been at least $18.00 per share (subject to adjustment in
accordance with Section 4 of the Warrant Agreement), on each of twenty (20)
trading days within any thirty (30) trading day period ending on the third
business day prior to the date on which notice of redemption is given;
  

2.

The Private Warrants held by the undersigned and/or their Permitted Transferees
may be exercised on a “cashless basis” in accordance with Section 3.3.1(c) of
the Warrant Agreement) at any time after notice of redemption shall have been
given by the Company pursuant to Section 6.2 of the Warrant Agreement and prior
to the Redemption Date. In the event the Company determines to require all
holders of Warrants to exercise their Warrants on a “cashless basis” pursuant to
Section 3.3.1(b) of the Warrant Agreement, the notice of redemption will contain
the information necessary to calculate the number of Ordinary Shares to be
received upon exercise of the Warrants, including the “Fair Market Value” in
such case. On and after the Redemption Date, the Record Holder of the Private
Warrants shall have no further rights with respect to the Private Warrants
except to receive the Redemption Price upon surrender of the Private Warrants;
and
  

3.

In case the Private Warrants are transferred to a Permitted Transferee, it shall
be a condition to such transfer (the “Transfer Condition”) that such Permitted
Transferee executes and delivers to the Company a joinder agreement to this
Agreement in the form attached hereto as Exhibit A, by which such Permitted
Transferee shall by bound by the terms and conditions of this Agreement. For the
avoidance of doubt, any transfer of the Private Warrants to any Permitted
Transferee without meeting the Transfer Condition shall be null and void.

This Agreement constitutes the entire understanding of the parties hereto
relating to the subject matter hereof and supersedes all prior agreements,
understandings, arrangements, promises and commitments, whether written or oral,
express or implied, relating to the subject matter hereof.

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