INVESTMENT
MANAGEMENT TRUST AGREEMENT


 


This
Investment Management Trust Agreement (this “Agreement”) is made effective as of March 14, 2019, by
and between Trine Acquisition Corp., a Delaware corporation (the “Company”), and Continental Stock Transfer
& Trust Company, a New York corporation (the “Trustee”).


 


WHEREAS,
the Company’s registration statements on Form S-1, File Nos. 333-229853 and 333-230295 (collectively, the “Registration Statement”)
and prospectus (the “Prospectus”) for the initial public offering of the Company’s units (the
“Units”), each of which consists of one share of the Company’s Class A common stock, par value
$0.0001 per share (the “Common Stock”), and one half of one redeemable warrant, each whole warrant entitling
the holder thereof to purchase one share of Common Stock (such initial public offering hereinafter referred to as the “Offering”),
has been declared effective as of the date hereof by the U.S. Securities and Exchange Commission; and


 


WHEREAS,
the Company has entered into an Underwriting Agreement (the “Underwriting Agreement”)
with BTIG, LLC and Cantor Fitzgerald & Co. as representatives (the “Representatives”) of the several
underwriters (the “Underwriters”) named therein; and


 


WHEREAS,
as described in the Prospectus, $261,000,000 of the gross proceeds of the Offering and sale of the Private Placement Warrants
(as defined in the Underwriting Agreement) (or $300,150,000, if the Underwriters’ over-allotment option is exercised in
full) will be delivered to the Trustee to be deposited and held in a segregated trust account located at all times in the United
States (the “Trust Account”) for the benefit of the Company and the holders of the
Common Stock included in the Units issued in the Offering as hereinafter provided (the amount to be delivered to the Trustee (and
any interest subsequently earned thereon) is referred to herein as the “Property,” the stockholders
for whose benefit the Trustee shall hold the Property will be referred to as the “Public Stockholders,”
and the Public Stockholders and the Company will be referred to together as the “Beneficiaries”);


 


WHEREAS,
pursuant to the Underwriting Agreement, a portion of the Property equal to $9,135,000 , or $10,505,250 if the Underwriters’
over-allotment option is exercised in full, is attributable to deferred underwriting discounts and commissions that will be payable
by the Company to the Underwriters 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;


 






    1


     


    

 


(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 Section 1(i) of the Agreement. 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 $9,135,000.


 


3.

(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;


 






    4


     


    

 


(h)
Provide any assurance that any Business Combination entered into by the Company or any other action taken by the Company is as
contemplated by 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 or similar private courier service, by certified mail (return receipt requested), by hand delivery

	 	Re:	Trust
    Account No.      Termination Letter


 


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 March 14, 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.

and Gentlemen:


 


Pursuant
to Section 1(i) of the Investment Management Trust Agreement between Trine Acquisition Corp. (the “Company”)
