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

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

market funds meeting the conditions of Rule 2a-7(d) 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; while
the account funds are invested or uninvested, 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, in the case of a
Termination Letter in a form substantially similar to the attached hereto as Exhibit A, acknowledged and agreed to by the
Representative, 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) the date which is the later of (1) 18 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;


 


(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 per share 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;


 


(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 clause (y) of 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 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;


 


(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 $4,375,000.


 


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;

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.


 


(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; provided, however, that no such change, amendment or modification to Section 1(i), 2(f) or Exhibit A
may be made without the prior written consent of the Representative.


 


(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 or by electronic mail:

Re:         Trust
Account- Termination Letter


 


Ladies and Gentlemen:


 


Pursuant
to Section 1(i) of the Investment Management Trust Agreement between Parabellum Acquisition Corp. (the “Company”)
and Continental Stock Transfer & Trust Company (the “Trustee”), dated as of September 27, 2021
(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 the Target Business (the “Business Combination”)
on or about [insert date]. The Company shall notify you at least seventy-two (72) hours in advance (or such shorter time as you
may agree) 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, 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 substantially 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.

Re:          Trust
Account - Termination Letter


 


Ladies and Gentlemen:


 


Pursuant
to Section 1(i) of the Investment Management Trust Agreement between Parabellum Acquisition Corp. (the “Company”)
and Continental Stock Transfer & Trust Company (the “Trustee”), dated as of September 27, 2021
(the “Trust Agreement”), this is to advise you that the Company has been unable to effect a business combination
with a Target Business (the “Business Combination”) within the time frame specified in the Company’s
amended and restated certificate of incorporation, as described in the Company’s Prospectus relating to the Offering. 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 liquidate all of the assets in the Trust Account and to
transfer the total proceeds into a segregated account held by you on behalf of the Beneficiaries to await distribution to the Public
Stockholders. The Company has selected                (1) as the effective date for the purpose of determining when the
Public Stockholders will be entitled to receive their share of the liquidation proceeds. You agree to be the Paying Agent of record
and, in your separate capacity as Paying Agent, agree to distribute said funds directly to the Company’s Public Stockholders
in accordance with the terms of the Trust Agreement and the amended and restated certificate of incorporation of the Company. Upon
the distribution of all the funds, net of any payments necessary for reasonable unreimbursed expenses related to liquidating the
