Trine Acquisition
Corp., a Delaware corporation and blank check company (the “Maker”), promises to pay to the order of Trine Sponsor
LLC or its registered assigns or successors in interest (the “Payee”), or order, the principal sum of up to
Three Hundred Thousand Dollars ($300,000) in lawful money of the United States of America, on the terms and conditions described
below. All payments on this Note shall be made by check or wire transfer of immediately available funds or as otherwise determined
by the Maker to such account as the Payee may from time to time designate by written notice in accordance with the provisions of
this Note.


 


1. Principal. The principal
balance of this Note shall be payable by the Maker on the earlier of: (i) June 30, 2019 or (ii) the date on which Maker consummates
an initial public offering of its securities. The principal balance may be prepaid at any time. Under no circumstances shall any
individual, including but not limited to any officer, director, employee or shareholder of the Maker, be obligated personally for
any obligations or liabilities of the Maker hereunder.


 


2. Interest. No interest shall
accrue on the unpaid principal balance of this Note.


 


3. Drawdown Requests. Maker
and Payee agree that Maker may request up to Three Hundred Thousand Dollars ($300,000) for costs reasonably related to Maker’s
initial public offering of its securities. The principal of this Note may be drawn down from time to time prior to the earlier
of: (i) June 30, 2019 or (ii) the date on which Maker consummates an initial public offering of its securities, upon written request
from Maker to Payee (each, a “Drawdown Request”). Each Drawdown Request must state the amount to be drawn down,
and must not be an amount less than Ten Thousand Dollars ($10,000) unless agreed upon by Maker and Payee. Payee shall fund each
Drawdown Request no later than five (5) business days after receipt of a Drawdown Request; provided, however, that the maximum
amount of drawdowns collectively under this Note is Three Hundred Thousand Dollars ($300,000). Once an amount is drawn down under
this Note, it shall not be available for future Drawdown Requests even if prepaid. No fees, payments or other amounts shall be
due to Payee in connection with, or as a result of, any Drawdown Request by Maker. Notwithstanding the foregoing, all payments
shall be applied first to payment in full of any costs incurred in the collection of any sum due under this Note, including (without
limitation) reasonable attorneys’ fees, and then to the reduction of the unpaid principal balance of this Note.


 


4. Application of Payments.
All payments shall be applied first to payment in full of any costs incurred in the collection of any sum due under this Note,
including (without limitation) reasonable attorney’s fees, then to the payment in full of any late charges and finally to
the reduction of the unpaid principal balance of this Note.


 


5. Events of Default. The following
shall constitute an event of default (“Event of Default”):

to Make Required Payments. Failure by Maker to pay the principal amount due pursuant to this Note within five (5) business
days of the date specified above.

the making by it of any assignment for the benefit of creditors, or the failure of Maker generally to pay its debts as such debts
become due, or the taking of corporate action by Maker in furtherance of any of the foregoing.


 






     

     


    

 


(c) Involuntary

of 60 consecutive days.


 


6. Remedies.


 


(a) Upon the occurrence
of an Event of Default specified in Section 5(a) hereof, Payee may, by written notice to Maker, declare this Note to be due immediately

protest with regard to the Note, all errors, defects and imperfections in any proceedings instituted by Payee under the terms of
this Note, and all benefits that might accrue to Maker by virtue of any present or future laws exempting any property, real or
personal, or any part of the proceeds arising from any sale of any such property, from attachment, levy or sale under execution,
or providing for any stay of execution, exemption from civil process, or extension of time for payment; and Maker agrees that any
real estate that may be levied upon pursuant to a judgment obtained by virtue hereof or any writ of execution issued hereon, may
be sold upon any such writ in whole or in part in any order desired by Payee.


 


8. Unconditional Liability.
Maker hereby waives all notices in connection with the delivery, acceptance, performance, default, or enforcement of the payment
of this Note, and agrees that its liability shall be unconditional, without regard to the liability of any other party, and shall
not be affected in any manner by any indulgence, extension of time, renewal, waiver or modification granted or consented to by
Payee, and consents to any and all extensions of time, renewals, waivers, or modifications that may be granted by Payee with respect

11. Severability. Any provision
contained in this Note which is prohibited or unenforceable in any jurisdiction shall, as to such jurisdiction, be ineffective
to the extent of such prohibition or unenforceability without invalidating the remaining provisions hereof, and any such prohibition
or unenforceability in any jurisdiction shall not invalidate or render unenforceable such provision in any other jurisdiction.


 


12. Trust Waiver. Notwithstanding
anything herein to the contrary, the Payee hereby waives any and all right, title, interest or claim of any kind (“Claim”)
in or to any distribution of or from the trust account to be established in which the proceeds of the initial public offering (the

as described in greater detail in the registration statement and prospectus to be filed with the Securities and Exchange Commission
in connection with the IPO, and hereby agrees not to seek recourse, reimbursement, payment or satisfaction for any Claim against
