upon and concurrently with the consummation of the Business Combination (as defined below) (the “Deferred Discount”);
and


 


WHEREAS, the Company and the Trustee desire
to enter into this Agreement to set forth the terms and conditions pursuant to which the Trustee shall hold the Property.


 


NOW THEREFORE, IT IS AGREED:


 


1. Agreements and Covenants of Trustee.
The Trustee hereby agrees and covenants to:


 


(a) Hold the Property in trust for the
Beneficiaries in accordance with the terms of this Agreement in the Trust Account established by the Trustee in the United States
at J.P. Morgan Chase Bank, N.A. and at a brokerage institution selected by the Trustee that is reasonably satisfactory to the Company;


 


(b) Manage, supervise and administer the
Trust Account subject to the terms and conditions set forth herein;


 


(c) In a timely manner, upon the written
instruction of the Company, invest and reinvest the Property solely in United States government securities within the meaning of
Section 2(a)(16) of the Investment Company Act of 1940, as amended, having a maturity of 180 days or less, or in money market funds
meeting the conditions of paragraphs (d)(1), (d)(2), (d)(3) and (d)(4) of Rule 2a-7 promulgated under the Investment Company Act
of 1940, as amended (or any successor rule), which invest only in direct U.S. government treasury obligations, as determined by
the Company; it being understood that the Trust Account will earn no interest while account funds are uninvested awaiting the Company’s
instructions hereunder and the Trustee may earn bank credits or other consideration;


 






     


     


    

 


(d) Collect and receive, when due, all
interest or other income arising from the Property, which shall become part of the “Property,” as such
term is used herein;


 


(e) Promptly notify the Company and the
Representative of all communications received by the Trustee with respect to any Property requiring action by the Company;


 


(f) Supply any necessary information or
documents as may be requested by the Company (or its authorized agents) in connection with the Company’s preparation of the
tax returns relating to assets held in the Trust Account;


 


(g) Participate in any plan or proceeding
for protecting or enforcing any right or interest arising from the Property if, as and when instructed by the Company to do so;


 


(h) Render to the Company monthly written
statements of the activities of, and amounts in, the Trust Account reflecting all receipts and disbursements of the Trust Account;


 


(i) Commence liquidation of the Trust
Account only after and promptly after (x) receipt of, and only in accordance with, the terms of a letter from the Company (“Termination Letter”)
in a form substantially similar to that attached hereto as either Exhibit A or Exhibit B, as applicable, signed on
behalf of the Company by its Chief Executive Officer, Chief Financial Officer, President, Executive Vice President, Vice President,
Secretary or Chairman of the board of directors of the Company (the “Board”) or other authorized officer
of the Company, and complete the liquidation of the Trust Account and distribute the Property in the Trust Account, including interest
not previously released to the Company to pay its taxes (less up to $100,000 of interest that may be released to the Company to
pay dissolution expenses), only as directed in the Termination Letter and the other documents referred to therein, or (y) upon
the date which is, the later of (1) 24 months after the closing of the Offering and (2) such later date as may be approved by the
Company’s stockholders in accordance with the Company’s amended and restated certificate of incorporation if a Termination
Letter has not been received by the Trustee prior to such date, in which case the Trust Account shall be liquidated in accordance
with the procedures set forth in the Termination Letter attached as Exhibit B and the Property in the Trust Account, including
interest not previously released to the Company to pay its taxes (less up to $100,000 of interest that may be released to the Company
to pay dissolution expenses) shall be distributed to the Public Stockholders of record as of such date; and provided, however,
that in the event the Trustee receives a Termination Letter in a form substantially similar to Exhibit B hereto, or if the
Trustee begins to liquidate the Property because it has received no such Termination Letter by the date specified in clause (y)
of this Section 1(i), the Trustee shall keep the Trust Account open until twelve (12) months following the date the Property has
been distributed to the Public Stockholders.


 


(j) Upon written request from the Company,
which may be given from time to time in a form substantially similar to that attached hereto as Exhibit C, withdraw from
the Trust Account and distribute to the Company the amount of interest earned on the Property requested by the Company to cover
any tax obligation owed by the Company as a result of assets of the Company or interest or other income earned on the Property,
which amount shall be delivered directly to the Company by electronic funds transfer or other method of prompt payment, and the
Company shall forward such payment to the relevant taxing authority; provided, however, that to the extent there
is not sufficient cash in the Trust Account to pay such tax obligation, the Trustee shall liquidate such assets held in the Trust
Account as shall be designated by the Company in writing to make such distribution, so long as there is no reduction in the principal
amount initially deposited in the Trust Account; provided, further, that if the tax to be paid is a franchise tax,
the written request by the Company to make such distribution shall be accompanied by a copy of the franchise tax bill from the
State of Delaware for the Company (it being acknowledged and agreed that any such amount in excess of interest income earned on
the Property shall not be payable from the Trust Account). The written request of the Company referenced above shall constitute
presumptive evidence that the Company is entitled to said funds, and the Trustee shall have no responsibility to look beyond said
request;


 






    2


     


    

 


(k) Upon written request from the Company,
which may be given from time to time in a form substantially similar to that attached hereto as Exhibit D, the Trustee shall
distribute on behalf of the Company the amount requested by the Company to be used to redeem shares of Common Stock from Public
Stockholders properly submitted in connection with a stockholder vote to approve an amendment to the Company’s amended and
restated certificate of incorporation to modify the substance or timing of the ability of Public Stockholders to seek redemption
in connection with an initial Business Combination or the Company’s obligation to redeem 100% of its public shares of Common
Stock if the Company has not consummated an initial Business Combination within such time as is described in the Company’s
amended and restated certificate of incorporation. The written request of the Company referenced above shall constitute presumptive
evidence that the Company is entitled to distribute said funds, and the Trustee shall have no responsibility to look beyond said
request; and


 


(l) Not make any withdrawals or distributions
from the Trust Account other than pursuant to Section 1(i), (j) or (k) above.


 


2. Agreements and Covenants of the Company.
The Company hereby agrees and covenants to:


 


(a) Give all instructions to the Trustee
hereunder in writing, signed by the Company’s Chairman of the Board, Chief Executive Officer, Chief Financial Officer, President,
Executive Vice President, Vice President or Secretary. In addition, except with respect to its duties under Sections 1(i),
1(j) and 1(k) hereof, the Trustee shall be entitled to rely on, and shall be protected in relying on, any verbal
or telephonic advice or instruction which it, in good faith and with reasonable care, believes to be given by any one of the persons
authorized above to give written instructions, provided that the Company shall promptly confirm such instructions in writing;


 


(b) Subject to Section 4 hereof,
hold the Trustee harmless and indemnify the Trustee from and against any and all expenses, including reasonable counsel fees and
disbursements, or losses suffered by the Trustee in connection with any action taken by it hereunder and in connection with any
action, suit or other proceeding brought against the Trustee involving any claim, or in connection with any claim or demand, which
in any way arises out of or relates to this Agreement, the services of the Trustee hereunder, or the Property or any interest earned
on the Property, except for expenses and losses resulting from the Trustee’s gross negligence, fraud or willful misconduct.
Promptly after the receipt by the Trustee of notice of demand or claim or the commencement of any action, suit or proceeding, pursuant
to which the Trustee intends to seek indemnification under this Section 2(b), it shall notify the Company in writing of
such claim (hereinafter referred to as the “Indemnified Claim”). The Trustee shall
have the right to conduct and manage the defense against such Indemnified Claim; provided that the Trustee shall obtain
the consent of the Company with respect to the selection of counsel, which consent shall not be unreasonably withheld. The Trustee
may not agree to settle any Indemnified Claim without the prior written consent of the Company, which such consent shall not be
unreasonably withheld. The Company may participate in such action with its own counsel;


 


(c) Pay the Trustee the fees set forth
on Schedule A hereto, including an initial acceptance fee, annual administration fee, and transaction processing fee which
fees shall be subject to modification by the parties from time to time. It is expressly understood that the Property shall not
be used to pay such fees unless and until the closing of the Business Combination (defined below). The Company shall pay the Trustee
the initial acceptance fee and the first annual administration fee at the consummation of the Offering. The Trustee shall refund
to the Company the annual administration fee (on a pro rata basis) with respect to any period after the liquidation of the Trust
Account. The Company shall not be responsible for any other fees or charges of the Trustee except as set forth in this Section
2(c), Schedule A and as may be provided in Section 2(b) hereof;


 


(d) In connection with any vote of the
Company’s stockholders regarding a merger, capital stock exchange, asset acquisition, stock purchase, reorganization or similar
business combination involving the Company and one or more businesses (the “Business Combination”),
provide to the Trustee an affidavit or certificate of the inspector of elections for the stockholder meeting verifying the vote
of such stockholders regarding such Business Combination;


 


(e) Provide the Representative with a
copy of any Termination Letter(s) and/or any other correspondence that is sent to the Trustee with respect to any proposed withdrawal
from the Trust Account promptly after it issues the same;


 






    3


     


    

 


(f) Unless otherwise agreed between the
Company and the Representative, ensure that any Instruction Letter (as defined in Exhibit A) delivered in connection with a Termination
Letter in the form of Exhibit A expressly provides that the Deferred Discount is paid directly to the account or accounts directed
by the Representative on behalf of the Underwriters prior to any transfer of the funds held in the Trust Account to the Company
or any other person;


 


(g) Instruct the Trustee to make only
those distributions that are permitted under this Agreement, and refrain from instructing the Trustee to make any distributions
that are not permitted under this Agreement; and


 


(h) Within four (4) business days after
the Underwriters exercise the over-allotment option (or any unexercised portion thereof) or such over-allotment expires, provide
the Trustee with a notice in writing of the total amount of the Deferred Discount, which shall in no event be less than $8,750,000.


 


3. Limitations of Liability. The
Trustee shall have no responsibility or liability to:


 


(a) Imply obligations, perform duties,
inquire or otherwise be subject to the provisions of any agreement or document other than this Agreement and that which is expressly
set forth herein;


 


(b) Take any action with respect to the
Property, other than as directed in Section 1 hereof, and the Trustee shall have no liability to any third party except
for liability arising out of the Trustee’s gross negligence, fraud or willful misconduct;


 


(c) Institute any proceeding for the collection
of any principal and income arising from, or institute, appear in or defend any proceeding of any kind with respect to, any of
the Property unless and until it shall have received instructions from the Company given as provided herein to do so and the Company
shall have advanced or guaranteed to it funds sufficient to pay any expenses incident thereto;


 


(d) Refund any depreciation in principal
of any Property;


 


(e) Assume that the authority of any person
designated by the Company to give instructions hereunder shall not be continuing unless provided otherwise in such designation,
or unless the Company shall have delivered a written revocation of such authority to the Trustee;


 


(f) The other parties hereto or to anyone
else for any action taken or omitted by it, or any action suffered by it to be taken or omitted, in good faith and in the Trustee’s
best judgment, except for the Trustee’s gross negligence, fraud or willful misconduct. The Trustee may rely conclusively
and shall be protected in acting upon any order, notice, demand, certificate, opinion or advice of counsel (including counsel chosen
by the Trustee, which counsel may be the Company’s counsel), statement, instrument, report or other paper or document (not
only as to its due execution and the validity and effectiveness of its provisions, but also as to the truth and acceptability of
any information therein contained) which the Trustee believes, in good faith and with reasonable care, to be genuine and to be
signed or presented by the proper person or persons. The Trustee shall not be bound by any notice or demand, or any waiver, modification,
termination or rescission of this Agreement or any of the terms hereof, unless evidenced by a written instrument delivered to the
Trustee, signed by the proper party or parties and, if the duties or rights of the Trustee are affected, unless it shall give its
prior written consent thereto;


 


(g) Verify the accuracy of the information
contained in the Registration Statement;

(i) File information returns with respect
to the Trust Account with any local, state or federal taxing authority or provide periodic written statements to the Company documenting
the taxes payable by the Company, if any, relating to any interest income earned on the Property;


 


(j) Prepare, execute and file tax reports,
income or other tax returns and pay any taxes with respect to any income generated by, and activities relating to, the Trust Account,
regardless of whether such tax is payable by the Trust Account or the Company, including, but not limited to, franchise and income
tax obligations, except pursuant to Section 1(j) hereof; or


 


(k) Verify calculations, qualify or otherwise
approve the Company’s written requests for distributions pursuant to Sections 1(i), 1(j) or 1(k) hereof.


 


4. Trust Account Waiver. The Trustee
has no right of set-off or any right, title, interest or claim of any kind (“Claim”) to, or to any monies
in, the Trust Account, and hereby irrevocably waives any Claim to, or to any monies in, the Trust Account that it may have now
or in the future. In the event the Trustee has any Claim against the Company under this Agreement, including, without limitation,
under Section 2(b) or Section 2(c) hereof, the Trustee shall pursue such Claim solely against the Company and its
assets outside the Trust Account and not against the Property or any monies in the Trust Account.


 


5. Termination. This Agreement shall
terminate as follows:


 


(a) If the Trustee gives written notice
to the Company that it desires to resign under this Agreement, the Company shall use its reasonable efforts to locate a successor
trustee, pending which the Trustee shall continue to act in accordance with this Agreement. At such time that the Company notifies
the Trustee that a successor trustee has been appointed and has agreed to become subject to the terms of this Agreement, the Trustee
shall transfer the management of the Trust Account to the successor trustee, including but not limited to the transfer of copies
of the reports and statements relating to the Trust Account, whereupon this Agreement shall terminate; provided, however,
that in the event that the Company does not locate a successor trustee within ninety (90) days of receipt of the resignation notice
from the Trustee, the Trustee may submit an application to have the Property deposited with any court in the State of New York
or with the United States District Court for the Southern District of New York and upon such deposit, the Trustee shall be immune
from any liability whatsoever; or


 


(b) At such time that the Trustee has
completed the liquidation of the Trust Account and its obligations in accordance with the provisions of Section 1(i) hereof
(which section may not be amended under any circumstances) and distributed the Property in accordance with the provisions of the
Termination Letter, this Agreement shall terminate except with respect to Section 2(b).


 


6. Miscellaneous.


 


(a) The Company and the Trustee each acknowledge
that the Trustee will follow the security procedures set forth below with respect to funds transferred from the Trust Account.
The Company and the Trustee will each restrict access to confidential information relating to such security procedures to authorized
persons. Each party must notify the other party immediately if it has reason to believe unauthorized persons may have obtained
access to such confidential information, or of any change in its authorized personnel. In executing funds transfers, the Trustee
shall rely upon all information supplied to it by the Company, including, account names, account numbers, and all other identifying
information relating to a Beneficiary, Beneficiary’s bank or intermediary bank. Except for any liability arising out of the
Trustee’s gross negligence, fraud or willful misconduct, the Trustee shall not be liable for any loss, liability or expense
resulting from any error in the information or transmission of the funds.


 






    5


     


    

 


(b) This Agreement shall be governed by
and construed and enforced in accordance with the laws of the State of New York, without giving effect to conflicts of law principles
that would result in the application of the substantive laws of another jurisdiction. This Agreement may be executed in several
original or facsimile counterparts, each one of which shall constitute an original, and together shall constitute but one instrument.


 


(c) This Agreement contains the entire
agreement and understanding of the parties hereto with respect to the subject matter hereof. This Agreement or any provision hereof
may only be changed, amended or modified (other than to correct a typographical error) by a writing signed by each of the parties
hereto.


 


(d) This Agreement or any provision hereof
may only be changed, amended or modified pursuant to Section 6(c) hereof with the Consent of the Stockholders. For purposes
of this Section 6(d), the “Consent of the Stockholders”
means receipt by the Trustee of a certificate from the inspector of elections of the stockholder meeting certifying that the Company’s
stockholders of record as of a record date established in accordance with Section 213(a) of the Delaware General Corporation Law,
as amended (“DGCL”) (or any successor rule), who hold sixty-five percent (65%) or more of all then outstanding
shares of the Common Stock and Class B common stock, par value $0.0001 per share, of the Company voting together as a single class,
have voted in favor of such change, amendment or modification. No such amendment will affect any Public Stockholder who has otherwise
indicated his election to redeem his shares of Common Stock in connection with a stockholder vote sought to amend this Agreement
to modify the substance or timing of the Company’s obligation to redeem 100% of the Common Stock if the Company does not
complete its initial Business Combination within the time frame specified in the Company’s amended and restated certificate
of incorporation. Except for any liability arising out of the Trustee’s gross negligence, fraud or willful misconduct, the
Trustee may rely conclusively on the certification from the inspector or elections referenced above and shall be relieved of all
liability to any party for executing the proposed amendment in reliance thereon.


 


(e) The parties hereto consent to the
jurisdiction and venue of any state or federal court located in the City of New York, State of New York, for purposes of resolving
any disputes hereunder. AS TO ANY CLAIM, CROSS-CLAIM OR COUNTERCLAIM IN ANY WAY RELATING TO THIS AGREEMENT, EACH PARTY WAIVES THE
RIGHT TO TRIAL BY JURY.


 


(f) Any notice, consent or request to
be given in connection with any of the terms or provisions of this Agreement shall be in writing and shall be sent by express mail

Ladies and Gentlemen:


 


Pursuant to Section 1(i) of the Investment
Management Trust Agreement between Trine Acquisition Corp. (the “Company”) and Continental Stock Transfer
& Trust Company (the “Trustee”), dated as of [        ], 2019 (the “Trust Agreement”),
this is to advise you that the Company has entered into an agreement with              (the
“Target Business”) to consummate a business combination with Target Business (the “Business Combination”)
on or about [insert date]. The Company shall notify you at least forty-eight (48) hours in advance of the actual date of the consummation
of the Business Combination (the “Consummation Date”). Capitalized terms used but
not defined herein shall have the meanings set forth in the Trust Agreement.


 


In accordance with the terms of the Trust
Agreement, we hereby authorize you to commence to liquidate all of the assets of the Trust Account on [insert date], and to transfer
the proceeds to a segregated account held by you on behalf of the Beneficiaries to the effect that, on the Consummation Date, all
of the funds held in the Trust Account will be immediately available for transfer to the account or accounts that the Company shall
direct on the Consummation Date (including as directed to it by the Representative on behalf of the Underwriters (with respect
to the Deferred Discount)). It is acknowledged and agreed that while the funds are on deposit in the trust operating account at
J.P. Morgan Chase Bank, N.A. awaiting distribution, the Company will not earn any interest or dividends.


 


On the Consummation Date (i) counsel for
the Company shall deliver to you written notification that the Business Combination has been consummated, or will be consummated
concurrently with your transfer of funds to the accounts as directed by the Company (the “Notification”)
and (ii) the Company shall deliver to you (a) a certificate of the Chief Executive Officer, which verifies that the Business Combination
has been approved by a vote of the Company’s stockholders, if a vote is held and (b) a joint written instruction signed by
the Company and the Representative with respect to the transfer of the funds held in the Trust Account, including payment of amounts
owed to public stockholders who have properly exercised their redemption rights and payment of the Deferred Discount to the Representative
from the Trust Account (the “Instruction Letter”). You are hereby directed and authorized to transfer
the funds held in the Trust Account immediately upon your receipt of the Notification and the Instruction Letter, in accordance
with the terms of the Instruction Letter. In the event that certain deposits held in the Trust Account may not be liquidated by
the Consummation Date without penalty, you will notify the Company in writing of the same and the Company shall direct you as to
whether such funds should remain in the Trust Account and be distributed after the Consummation Date to the Company. Upon the distribution
of all the funds, net of any payments necessary for reasonable unreimbursed expenses related to liquidating the Trust Account,
your obligations under the Trust Agreement shall be terminated.


 


In the event that the Business Combination
is not consummated on the Consummation Date described in the notice thereof and we have not notified you on or before the original
Consummation Date of a new Consummation Date, then upon receipt by the Trustee of written instructions from the Company, the funds
held in the Trust Account shall be reinvested as provided in Section 1(c) of the Trust Agreement on the business day immediately
following the Consummation Date as set forth in such notice as soon thereafter as possible.

, 20     and to transfer the total proceeds into a segregated account held by you on behalf of the Beneficiaries
