that the Trust Account will earn no interest while account funds are uninvested awaiting the Company’s instructions hereunder;
while account funds are invested or uninvested, the Trustee may earn bank credits or other consideration;


 






    	 



    	 



    

 


(d) Collect
and receive, when due, all principal, 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 or in connection with the preparation or completion

(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 the 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 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 (which interest
shall be net of taxes payable, and 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) 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 Charter 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 (which interest shall be net of taxes payable, and 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; provided, however, that the Trustee has no obligation to monitor or question the Company’s position that
an allocation has been made for taxes payable;


 


(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, including any franchise tax obligations, 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,
as applicable; 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 and a written statement from the principal financial
officer of the Company setting forth the actual amount payable (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

Stock the amount required to pay for redeemed shares of Common Stock from Public Stockholders in connection with a stockholder

in connection with a Business Combination or to redeem 100% of the shares of Common Stock included in the Units sold in the Offering
if the Company does not complete a Business Combination within the time period set forth in the Company’s Charter or (ii)
with respect to any other provision relating to stockholders’ rights or pre-initial Business Combination activity. 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 Sections 1(i), 1(j) or 1(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 the disbursements are made to the Company pursuant to Section 1(i) solely in
connection with the completion of a 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 and thereafter on the anniversary of the Effective
Date. 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 (which inspector of elections may be the Trustee) 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) Instruct

provide in any Instruction Letter (as defined in Exhibit A) delivered in connection with a Termination Letter in the form of Exhibit
A that the Deferred Discount be 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.

(e) Assume
that the authority of any person designated by the Company to give instructions hereunder shall not be continuing unless provided

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

 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,

(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

(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) and Section 4;
or


 


(c) If
the Offering is not consummated within ten (10) business days of the date of this Agreement, in which case any funds received by
the Trustee from the Company or any sponsor, as applicable, shall be returned promptly following the receipt by the Trustee of
written instructions from the Company.


 


 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.

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

    	5



    	 



    

 


(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
(i) 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,

of the Company voting together as a single class, have voted in favor of such change, amendment or modification, or (ii) the Company’s
stockholders of record as of the record date who hold sixty-five percent (65%) or more of all then outstanding shares of the Common
Stock of the Company voting together as a single class, have delivered to the Trustee a signed writing approving such change, amendment
or modification. No such amendment will affect any Public Stockholder who has otherwise indicated his, her or its election to redeem
his, her or its shares of Common Stock in connection with a stockholder vote sought to amend this Agreement, including a corresponding
change to the Charter. Except for any liability arising out of the Trustee’s gross negligence, fraud or willful misconduct,

Re: Trust Account
- Termination Letter


 


Dear
Mr. Wolf and Ms. Gonzalez:


 


 Pursuant
to Section 1(i) of the Investment Management Trust Agreement between Bannix Acquisition Corp. (the “Company”)
and Continental Stock Transfer & Trust Company (the “Trustee”), dated as of _________, 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, neither the Company nor the Representative will
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 the Deferred Discount 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


 


 Dear
Mr. Wolf and Ms. Gonzalez:


 


Pursuant
to Section 1(i) of the Investment Management Trust Agreement between Bannix Acquisition Corp.
(the “Company”) and Continental Stock Transfer & Trust Company (the “Trustee”),
dated as of _________, 2021 (the “Trust Agreement”), this is to advise you that the Company did not
effect a business combination with a Target Business (the “Business Combination”) within the time frame
specified in the Company’s Charter, 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
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 [_________, 20__]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
