	 	Re:	Initial Public Offering


 


Ladies and Gentlemen:


 


This letter agreement is being
delivered to you in accordance with the Underwriting Agreement (the “Underwriting Agreement”) entered into by
and between Plutonian Acquisition Corp., a Delaware corporation (the “Company”), and EF Hutton, division of
Benchmark Investments, LLC, as Representative (the “Representative”) of the several underwriters named on Schedule
A thereto (the “Underwriters”), relating to an underwritten initial public offering (the “IPO”)
of the Company’s units (the “Units”), each comprised of one share of common stock of the Company, $0.0001
par value (the “Common Stock”), one warrant, where each warrant entitles the holder to purchase one share of
Common Stock at a price of $11.50 per share (the “Warrants”), and one right to receive one-sixth (1/6) of one
share of Common Stock (the “Rights”). Certain capitalized terms used herein are defined in paragraph 15 hereof.


 


In order to induce the Company
and the Underwriters to enter into the Underwriting Agreement and to proceed with the IPO, and in recognition of the benefit that such
IPO will confer upon the undersigned Insider as a stockholder of the Company, and for other good and valuable consideration, the receipt
and sufficiency of which are hereby acknowledged, the undersigned Insider hereby agrees with the Company as follows:


 


1. If the Company solicits approval
of its stockholders of a Business Combination, the undersigned Insider will vote all shares of Common Stock beneficially owned by him,
her or it, whether acquired before, in or after the IPO, in favor of such Business Combination.


 


2. The undersigned hereby agrees
that in the event that the Company fails to consummate a Business Combination within nine (9) months, the time period by which the Company
must consummate a Business Combination may be extended by up to nine (9) months. For such extension, Plutonian Investments LLC (and/or
its affiliates or designees) is required to deposit into the Trust Fund for each additional one-month period, an aggregate of $165,000,
or up to $189,750 if the Underwriters' over-allotment option was exercised in full (in either case, $0.033 per IPO Share per month) on
or prior to the date of the applicable deadline. Such extension payments would be made in the form of non-interest bearing loans to the
Company (the “Extension Loans”), which are due and payable on the consummation of the initial Business Combination
out of the proceeds of the Trust Fund released to the Company, or at the option of Plutonian Investments LLC, all or a portion of all
of the total loan amount may be converted into Units at a price of $10.00 per Unit, which Units will be identical to the Private Units.
If the Company does not complete a Business Combination, the Extension Loans will be repaid out of funds not held in the trust account,
and only to the extent available.


 


3. (a) Unless the Company’s
stockholders are previously given the option to redeem their shares in connection with amending applicable documents to extend the time
that the Company has to complete a Business Combination, if the Company fails to consummate a Business Combination within 9 months from
the closing of the IPO (or, in the event that the Company extended the period of time to consummate a business combination up to 18 months
from the closing of the IPO, as specified in the Company’s amended and restated certificate of incorporation), then the undersigned
Insider shall take all reasonable steps to (i) cause the Trust Fund to be liquidated and distributed to the holders of the IPO Shares
and (ii) cause the Company to liquidate as soon as reasonably practicable.


 






     


    


    

 


(b) The undersigned Insider
hereby waives any and all right, title, interest or claim of any kind in or to any distribution of the Trust Fund and any remaining net
assets of the Company as a result of such liquidation with respect to his, her or its Insider Shares (“Claim”)
and hereby waives any Claim the undersigned Insider may have in the future as a result of, or arising out of, any contracts or agreements
with the Company and will not seek recourse against the Trust Fund for any reason whatsoever.


  


4. During the period ending
180 days after the effective date of the Underwriting Agreement, the undersigned Insider hereby agrees he, she or it shall not, without
the prior written consent of the Representative, (i) sell, offer to sell, contract or agree to sell, hypothecate, pledge, grant any option
to purchase or otherwise dispose of or agree to dispose of, directly or indirectly, or establish or increase a put equivalent position
or liquidate or decrease a call equivalent position within the meaning of Section 16 of the Securities Exchange Act of 1934, as amended
(the “Exchange Act”), and the rules and regulations of the U.S. Securities and Exchange Commission (the “SEC”)
promulgated thereunder, with respect to any Units, shares of Common Stock, Warrants, Rights or any securities convertible into, or exercisable,
or exchangeable for, shares of Common Stock owned by it, him or her, (ii) enter into any swap or other arrangement that transfers to another,
in whole or in part, any of the economic consequences of ownership of any Units, shares of Common Stock, Warrants, Rights or any securities
convertible into, or exercisable, or exchangeable for, shares of Common Stock owned by it, him or her, whether any such transaction is
to be settled by delivery of such securities, in cash or otherwise, or (iii) publicly announce any intention to effect any transaction
specified in clause (i) or (ii). The undersigned Insider acknowledges and agrees that, prior to the effective date of any release or waiver
of the restrictions set forth in this paragraph 4, the Company shall announce the impending release or waiver by press release through
a major news service at least two business days before the effective date of the release or waiver. Any release or waiver granted shall
only be effective two business days after the publication date of such press release. The provisions of this paragraph will not apply
if (i) the release or waiver is effected solely to permit a transfer of securities that is not for consideration and (ii) the transferee
has agreed in writing to be bound by the same terms described in this letter agreement to the extent and for the duration that such terms
remain in effect at the time of the transfer.


 


5. The undersigned Insider will
escrow all of his, her or its Insider Shares pursuant to the terms of a Stock Escrow Agreement, which the Company will enter into with
the undersigned Insider and an escrow agent acceptable to the Company.


 


6. In order to minimize potential
conflicts of interest which may arise from multiple affiliations, the undersigned Insider agrees to present to the Company for its consideration,
prior to presentation to any other person or entity, any suitable opportunity to acquire a target business, until the earlier of the consummation
by the Company of a Business Combination or the liquidation of the Company, subject to any pre-existing fiduciary and contractual obligations
the undersigned Insider might have.


 


7. The undersigned Insider acknowledges
and agrees that prior to entering into a Business Combination with a target business that is affiliated with any Insiders or their affiliates,
including any company that is a portfolio company of, or otherwise affiliated with, or has received financial investment from, an entity
with which any Insider or its affiliates is affiliated, such transaction must be approved by a majority of the Company’s disinterested
independent directors and the Company must obtain an opinion from an independent investment banking firm (or another independent firm
that commonly renders valuation opinions for the type of target business that the Company is seeking to acquire) that such Business Combination
is fair to the Company’s unaffiliated stockholders from a financial point of view.


 


8. Neither the undersigned Insider,
any member of the family of the undersigned Insider, nor any affiliate of the undersigned Insider will be entitled to receive and will
not accept any compensation or other cash payment prior to, or for services rendered in connection with, the consummation of the Business
Combination; provided that the Company shall be allowed to repay working capital loans (the “Working Capital Loans”)
made by the undersigned Insider to the Company in cash upon consummation of the Business Combination. Notwithstanding the foregoing, the
undersigned Insider and any affiliate of the undersigned Insider shall be entitled to reimbursement from the Company for their out-of-pocket
expenses incurred in connection with identifying, investigating and consummating a Business Combination.

	 	Re:	Initial Public Offering


 


Ladies and Gentlemen:


 


This letter agreement is being
delivered to you in accordance with the Underwriting Agreement (the “Underwriting Agreement”) entered into by
and between Plutonian Acquisition Corp., a Delaware corporation (the “Company”), and EF Hutton, division of
Benchmark Investments, LLC, as Representative (the “Representative”) of the several underwriters named on Schedule
A thereto (the “Underwriters”), relating to an underwritten initial public offering (the “IPO”)
of the Company’s units (the “Units”), each comprised of one share of common stock of the Company, $0.0001
par value (the “Common Stock”), one warrant, where each warrant entitles the holder to purchase one share of
Common Stock at a price of $11.50 per share (the “Warrants”), and one right to receive one-sixth (1/6) of one
share of Common Stock (the “Rights”). Certain capitalized terms used herein are defined in paragraph 15 hereof.


 


In order to induce the Company
and the Underwriters to enter into the Underwriting Agreement and to proceed with the IPO, and in recognition of the benefit that such
IPO will confer upon the undersigned Insider as a stockholder of the Company, and for other good and valuable consideration, the receipt
and sufficiency of which are hereby acknowledged, the undersigned Insider hereby agrees with the Company as follows:


 


1. If the Company solicits approval
of its stockholders of a Business Combination, the undersigned Insider will vote all shares of Common Stock beneficially owned by him,
her or it, whether acquired before, in or after the IPO, in favor of such Business Combination.


 


2. The undersigned hereby agrees
that in the event that the Company fails to consummate a Business Combination within nine (9) months, the time period by which the Company
must consummate a Business Combination may be extended by up to nine (9) months. For such extension, Plutonian Investments LLC (and/or
its affiliates or designees) is required to deposit into the Trust Fund for each additional one-month period, an aggregate of $165,000,
or up to $189,750 if the Underwriters' over-allotment option was exercised in full (in either case, $0.033 per IPO Share per month) on
or prior to the date of the applicable deadline. Such extension payments would be made in the form of non-interest bearing loans to the
Company (the “Extension Loans”), which are due and payable on the consummation of the initial Business Combination
out of the proceeds of the Trust Fund released to the Company, or at the option of Plutonian Investments LLC, all or a portion of all
of the total loan amount may be converted into Units at a price of $10.00 per Unit, which Units will be identical to the Private Units.
If the Company does not complete a Business Combination, the Extension Loans will be repaid out of funds not held in the trust account,
and only to the extent available.


 


3. (a) Unless the Company’s
stockholders are previously given the option to redeem their shares in connection with amending applicable documents to extend the time
that the Company has to complete a Business Combination, if the Company fails to consummate a Business Combination within 9 months from
the closing of the IPO (or, in the event that the Company extended the period of time to consummate a business combination up to 18 months
from the closing of the IPO, as specified in the Company’s amended and restated certificate of incorporation), then the undersigned
Insider shall take all reasonable steps to (i) cause the Trust Fund to be liquidated and distributed to the holders of the IPO Shares
and (ii) cause the Company to liquidate as soon as reasonably practicable.


 






     


    


    

 


(b) The undersigned Insider
hereby waives any and all right, title, interest or claim of any kind in or to any distribution of the Trust Fund and any remaining net
assets of the Company as a result of such liquidation with respect to his, her or its Insider Shares (“Claim”)
and hereby waives any Claim the undersigned Insider may have in the future as a result of, or arising out of, any contracts or agreements
with the Company and will not seek recourse against the Trust Fund for any reason whatsoever.


  


4. During the period ending
180 days after the effective date of the Underwriting Agreement, the undersigned Insider hereby agrees he, she or it shall not, without
the prior written consent of the Representative, (i) sell, offer to sell, contract or agree to sell, hypothecate, pledge, grant any option
to purchase or otherwise dispose of or agree to dispose of, directly or indirectly, or establish or increase a put equivalent position
or liquidate or decrease a call equivalent position within the meaning of Section 16 of the Securities Exchange Act of 1934, as amended
(the “Exchange Act”), and the rules and regulations of the U.S. Securities and Exchange Commission (the “SEC”)
promulgated thereunder, with respect to any Units, shares of Common Stock, Warrants, Rights or any securities convertible into, or exercisable,
or exchangeable for, shares of Common Stock owned by it, him or her, (ii) enter into any swap or other arrangement that transfers to another,
in whole or in part, any of the economic consequences of ownership of any Units, shares of Common Stock, Warrants, Rights or any securities
convertible into, or exercisable, or exchangeable for, shares of Common Stock owned by it, him or her, whether any such transaction is
to be settled by delivery of such securities, in cash or otherwise, or (iii) publicly announce any intention to effect any transaction
specified in clause (i) or (ii). The undersigned Insider acknowledges and agrees that, prior to the effective date of any release or waiver
of the restrictions set forth in this paragraph 4, the Company shall announce the impending release or waiver by press release through
a major news service at least two business days before the effective date of the release or waiver. Any release or waiver granted shall
only be effective two business days after the publication date of such press release. The provisions of this paragraph will not apply
if (i) the release or waiver is effected solely to permit a transfer of securities that is not for consideration and (ii) the transferee
has agreed in writing to be bound by the same terms described in this letter agreement to the extent and for the duration that such terms
remain in effect at the time of the transfer.


 


5. The undersigned Insider will
escrow all of his, her or its Insider Shares pursuant to the terms of a Stock Escrow Agreement, which the Company will enter into with
the undersigned Insider and an escrow agent acceptable to the Company.


 


6. In order to minimize potential
conflicts of interest which may arise from multiple affiliations, the undersigned Insider agrees to present to the Company for its consideration,
prior to presentation to any other person or entity, any suitable opportunity to acquire a target business, until the earlier of the consummation
by the Company of a Business Combination or the liquidation of the Company, subject to any pre-existing fiduciary and contractual obligations
the undersigned Insider might have.


 


7. The undersigned Insider acknowledges
and agrees that prior to entering into a Business Combination with a target business that is affiliated with any Insiders or their affiliates,
including any company that is a portfolio company of, or otherwise affiliated with, or has received financial investment from, an entity
with which any Insider or its affiliates is affiliated, such transaction must be approved by a majority of the Company’s disinterested
independent directors and the Company must obtain an opinion from an independent investment banking firm (or another independent firm
that commonly renders valuation opinions for the type of target business that the Company is seeking to acquire) that such Business Combination
is fair to the Company’s unaffiliated stockholders from a financial point of view.


 


8. Neither the undersigned Insider,
any member of the family of the undersigned Insider, nor any affiliate of the undersigned Insider will be entitled to receive and will
not accept any compensation or other cash payment prior to, or for services rendered in connection with, the consummation of the Business
Combination; provided that the Company shall be allowed to repay working capital loans (the “Working Capital Loans”)
made by the undersigned Insider to the Company in cash upon consummation of the Business Combination. Notwithstanding the foregoing, the
undersigned Insider and any affiliate of the undersigned Insider shall be entitled to reimbursement from the Company for their out-of-pocket
expenses incurred in connection with identifying, investigating and consummating a Business Combination.

9. Neither the undersigned Insider,
any member of the family of the undersigned Insider, nor any affiliate of the undersigned Insider will be entitled to receive or accept
a finder’s fee or any other compensation in the event the undersigned Insider, any member of the family of the undersigned Insider
or any affiliate of the undersigned Insider originates a Business Combination.

agrees to be a director of the Company until the earlier of the consummation by the Company of a Business Combination or the liquidation
of the Company. The undersigned Insider’s biographical information previously furnished to the Company and the Representative is

	 	Re:	Initial Public Offering


 


Ladies and Gentlemen:


 


This letter agreement is being
delivered to you in accordance with the Underwriting Agreement (the “Underwriting Agreement”) entered into by
and between Plutonian Acquisition Corp., a Delaware corporation (the “Company”), and EF Hutton, division of
Benchmark Investments, LLC, as Representative (the “Representative”) of the several underwriters named on Schedule
A thereto (the “Underwriters”), relating to an underwritten initial public offering (the “IPO”)
of the Company’s units (the “Units”), each comprised of one share of common stock of the Company, $0.0001
par value (the “Common Stock”), one warrant, where each warrant entitles the holder to purchase one share of
Common Stock at a price of $11.50 per share (the “Warrants”), and one right to receive one-sixth (1/6) of one
share of Common Stock (the “Rights”). Certain capitalized terms used herein are defined in paragraph 15 hereof.


 


In order to induce the Company
and the Underwriters to enter into the Underwriting Agreement and to proceed with the IPO, and in recognition of the benefit that such
IPO will confer upon the undersigned Insider as a stockholder of the Company, and for other good and valuable consideration, the receipt
and sufficiency of which are hereby acknowledged, the undersigned Insider hereby agrees with the Company as follows:


 


1. If the Company solicits approval
of its stockholders of a Business Combination, the undersigned Insider will vote all shares of Common Stock beneficially owned by him,
her or it, whether acquired before, in or after the IPO, in favor of such Business Combination.


 


2. The undersigned hereby agrees
that in the event that the Company fails to consummate a Business Combination within nine (9) months, the time period by which the Company
must consummate a Business Combination may be extended by up to nine (9) months. For such extension, Plutonian Investments LLC (and/or
its affiliates or designees) is required to deposit into the Trust Fund for each additional one-month period, an aggregate of $165,000,
or up to $189,750 if the Underwriters' over-allotment option was exercised in full (in either case, $0.033 per IPO Share per month) on
or prior to the date of the applicable deadline. Such extension payments would be made in the form of non-interest bearing loans to the
Company (the “Extension Loans”), which are due and payable on the consummation of the initial Business Combination
out of the proceeds of the Trust Fund released to the Company, or at the option of Plutonian Investments LLC, all or a portion of all
of the total loan amount may be converted into Units at a price of $10.00 per Unit, which Units will be identical to the Private Units.
If the Company does not complete a Business Combination, the Extension Loans will be repaid out of funds not held in the trust account,
and only to the extent available.


 


3. (a) Unless the Company’s
stockholders are previously given the option to redeem their shares in connection with amending applicable documents to extend the time
that the Company has to complete a Business Combination, if the Company fails to consummate a Business Combination within 9 months from
the closing of the IPO (or, in the event that the Company extended the period of time to consummate a business combination up to 18 months
from the closing of the IPO, as specified in the Company’s amended and restated certificate of incorporation), then the undersigned
Insider shall take all reasonable steps to (i) cause the Trust Fund to be liquidated and distributed to the holders of the IPO Shares
and (ii) cause the Company to liquidate as soon as reasonably practicable.


 






     


    


    

 


(b) The undersigned Insider
hereby waives any and all right, title, interest or claim of any kind in or to any distribution of the Trust Fund and any remaining net
assets of the Company as a result of such liquidation with respect to his, her or its Insider Shares (“Claim”)
and hereby waives any Claim the undersigned Insider may have in the future as a result of, or arising out of, any contracts or agreements
with the Company and will not seek recourse against the Trust Fund for any reason whatsoever.


  


4. During the period ending
180 days after the effective date of the Underwriting Agreement, the undersigned Insider hereby agrees he, she or it shall not, without
the prior written consent of the Representative, (i) sell, offer to sell, contract or agree to sell, hypothecate, pledge, grant any option
to purchase or otherwise dispose of or agree to dispose of, directly or indirectly, or establish or increase a put equivalent position
or liquidate or decrease a call equivalent position within the meaning of Section 16 of the Securities Exchange Act of 1934, as amended
(the “Exchange Act”), and the rules and regulations of the U.S. Securities and Exchange Commission (the “SEC”)
promulgated thereunder, with respect to any Units, shares of Common Stock, Warrants, Rights or any securities convertible into, or exercisable,
or exchangeable for, shares of Common Stock owned by it, him or her, (ii) enter into any swap or other arrangement that transfers to another,
in whole or in part, any of the economic consequences of ownership of any Units, shares of Common Stock, Warrants, Rights or any securities
convertible into, or exercisable, or exchangeable for, shares of Common Stock owned by it, him or her, whether any such transaction is
to be settled by delivery of such securities, in cash or otherwise, or (iii) publicly announce any intention to effect any transaction
specified in clause (i) or (ii). The undersigned Insider acknowledges and agrees that, prior to the effective date of any release or waiver
of the restrictions set forth in this paragraph 4, the Company shall announce the impending release or waiver by press release through
a major news service at least two business days before the effective date of the release or waiver. Any release or waiver granted shall
only be effective two business days after the publication date of such press release. The provisions of this paragraph will not apply
if (i) the release or waiver is effected solely to permit a transfer of securities that is not for consideration and (ii) the transferee
has agreed in writing to be bound by the same terms described in this letter agreement to the extent and for the duration that such terms
remain in effect at the time of the transfer.


 


5. The undersigned Insider will
escrow all of his, her or its Insider Shares pursuant to the terms of a Stock Escrow Agreement, which the Company will enter into with
the undersigned Insider and an escrow agent acceptable to the Company.


 


6. In order to minimize potential
conflicts of interest which may arise from multiple affiliations, the undersigned Insider agrees to present to the Company for its consideration,
prior to presentation to any other person or entity, any suitable opportunity to acquire a target business, until the earlier of the consummation
by the Company of a Business Combination or the liquidation of the Company, subject to any pre-existing fiduciary and contractual obligations
the undersigned Insider might have.


 


7. The undersigned Insider acknowledges
and agrees that prior to entering into a Business Combination with a target business that is affiliated with any Insiders or their affiliates,
including any company that is a portfolio company of, or otherwise affiliated with, or has received financial investment from, an entity
with which any Insider or its affiliates is affiliated, such transaction must be approved by a majority of the Company’s disinterested
independent directors and the Company must obtain an opinion from an independent investment banking firm (or another independent firm
that commonly renders valuation opinions for the type of target business that the Company is seeking to acquire) that such Business Combination
is fair to the Company’s unaffiliated stockholders from a financial point of view.


 


8. Neither the undersigned Insider,
any member of the family of the undersigned Insider, nor any affiliate of the undersigned Insider will be entitled to receive and will
not accept any compensation or other cash payment prior to, or for services rendered in connection with, the consummation of the Business
Combination; provided that the Company shall be allowed to repay working capital loans (the “Working Capital Loans”)
made by the undersigned Insider to the Company in cash upon consummation of the Business Combination. Notwithstanding the foregoing, the
undersigned Insider and any affiliate of the undersigned Insider shall be entitled to reimbursement from the Company for their out-of-pocket
expenses incurred in connection with identifying, investigating and consummating a Business Combination.

9. Neither the undersigned Insider,
any member of the family of the undersigned Insider, nor any affiliate of the undersigned Insider will be entitled to receive or accept
a finder’s fee or any other compensation in the event the undersigned Insider, any member of the family of the undersigned Insider
or any affiliate of the undersigned Insider originates a Business Combination.


 


10. The undersigned Insider
agrees to be a director/officer of the Company until the earlier of the consummation by the Company of a Business Combination or the liquidation
of the Company. The undersigned Insider’s biographical information previously furnished to the Company and the Representative is

the closing of the IPO (or, in the event that the Company extended the period of time to consummate a business combination up to 18 months
from the closing of the IPO, as specified in the Company’s amended and restated certificate of incorporation), then the undersigned
Insider shall take all reasonable steps to (i) cause the Trust Fund to be liquidated and distributed to the holders of the IPO Shares

with the Company and will not seek recourse against the Trust Fund for any reason whatsoever.


  


4. During the period ending

promulgated thereunder, with respect to any Units, shares of Common Stock, Warrants, Rights or any securities convertible into, or exercisable,
or exchangeable for, shares of Common Stock owned by it, him or her, (ii) enter into any swap or other arrangement that transfers to another,
in whole or in part, any of the economic consequences of ownership of any Units, shares of Common Stock, Warrants, Rights or any securities

specified in clause (i) or (ii). The undersigned Insider acknowledges and agrees that, prior to the effective date of any release or waiver
of the restrictions set forth in this paragraph 4, the Company shall announce the impending release or waiver by press release through
a major news service at least two business days before the effective date of the release or waiver. Any release or waiver granted shall

remain in effect at the time of the transfer.

by the Company of a Business Combination or the liquidation of the Company, subject to any pre-existing fiduciary and contractual obligations
the undersigned Insider might have.


 


7. The undersigned Insider acknowledges
and agrees that prior to entering into a Business Combination with a target business that is affiliated with any Insiders or their affiliates,
including any company that is a portfolio company of, or otherwise affiliated with, or has received financial investment from, an entity

independent directors and the Company must obtain an opinion from an independent investment banking firm (or another independent firm
that commonly renders valuation opinions for the type of target business that the Company is seeking to acquire) that such Business Combination
is fair to the Company’s unaffiliated stockholders from a financial point of view.


 


8. Neither the undersigned Insider,
any member of the family of the undersigned Insider, nor any affiliate of the undersigned Insider will be entitled to receive and will
not accept any compensation or other cash payment prior to, or for services rendered in connection with, the consummation of the Business

	 	Re:	Initial Public Offering


 


Ladies and Gentlemen:


 


This letter agreement is being
delivered to you in accordance with the Underwriting Agreement (the “Underwriting Agreement”) entered into by
and between Plutonian Acquisition Corp., a Delaware corporation (the “Company”), and EF Hutton, division of
Benchmark Investments, LLC, as Representative (the “Representative”) of the several underwriters named on Schedule
A thereto (the “Underwriters”), relating to an underwritten initial public offering (the “IPO”)
of the Company’s units (the “Units”), each comprised of one share of common stock of the Company, $0.0001
par value (the “Common Stock”), one warrant, where each warrant entitles the holder to purchase one share of
Common Stock at a price of $11.50 per share (the “Warrants”), and one right to receive one-sixth (1/6) of one
share of Common Stock (the “Rights”). Certain capitalized terms used herein are defined in paragraph 17 hereof.


 


In order to induce the Company
and the Underwriters to enter into the Underwriting Agreement and to proceed with the IPO, and in recognition of the benefit that such
IPO will confer upon the undersigned Insider as a stockholder of the Company, and for other good and valuable consideration, the receipt
and sufficiency of which are hereby acknowledged, the undersigned Insider hereby agrees with the Company as follows:


 


1. If the Company solicits approval
of its stockholders of a Business Combination, the undersigned Insider will vote all shares of Common Stock beneficially owned by him,
her or it, whether acquired before, in or after the IPO, in favor of such Business Combination.


 


2. The undersigned hereby agrees
that in the event that the Company fails to consummate a Business Combination within nine (9) months, the time period by which the Company
must consummate a Business Combination may be extended by up to nine (9) months. For such extension, Plutonian Investments LLC (and/or
its affiliates or designees) is required to deposit into the Trust Fund for each additional one-month period, an aggregate of $165,000,
or up to $189,750 if the Underwriters' over-allotment option was exercised in full (in either case, $0.033 per IPO Share per month) on
or prior to the date of the applicable deadline. Such extension payments would be made in the form of non-interest bearing loans to the
Company (the “Extension Loans”), which are due and payable on the consummation of the initial Business Combination
out of the proceeds of the Trust Fund released to the Company, or at the option of Plutonian Investments LLC, all or a portion of all
of the total loan amount may be converted into Units at a price of $10.00 per Unit, which Units will be identical to the Private Units.
If the Company does not complete a Business Combination, the Extension Loans will be repaid out of funds not held in the trust account,
and only to the extent available.


 


3. (a) Unless the Company’s
stockholders are previously given the option to redeem their shares in connection with amending applicable documents to extend the time
that the Company has to complete a Business Combination, if the Company fails to consummate a Business Combination within 9 months from
the closing of the IPO (or, in the event that the Company extended the period of time to consummate a business combination up to 18 months
from the closing of the IPO, as specified in the Company’s amended and restated certificate of incorporation), then the undersigned
Insider shall take all reasonable steps to (i) cause the Trust Fund to be liquidated and distributed to the holders of the IPO Shares
and (ii) cause the Company to liquidate as soon as reasonably practicable.


 






     


    


    

 


(b) The undersigned Insider
hereby waives any and all right, title, interest or claim of any kind in or to any distribution of the Trust Fund and any remaining net
assets of the Company as a result of such liquidation with respect to his, her or its Insider Shares and any shares underlying the Private
Units (“Claim”) and hereby waives any Claim the undersigned Insider may have in the future as a result of, or
arising out of, any contracts or agreements with the Company and will not seek recourse against the Trust Fund for any reason whatsoever.
The undersigned Insider acknowledges and agrees that there will be no distribution from the Trust Fund with respect to any shares of Common
Stock, Warrants or Rights underlying the Private Units, all of which will terminate on the Company’s liquidation.


 


3. In the event of the liquidation
of the Trust Fund, the undersigned Insider agrees to indemnify and hold harmless the Company against any and all loss, liability, claims,
damage and expense whatsoever (including, but not limited to, any and all legal or other expenses reasonably incurred in investigating,
preparing or defending against any litigation, whether pending or threatened, or any claim whatsoever) which the Company may become subject
as a result of any claim by any target business or vendor or other person who is owed money by the Company for services rendered or products
sold or contracted for, but only to the extent necessary to ensure that such loss, liability, claim, damage or expense does not reduce
the amount of funds in the Trust Fund; provided that such indemnity shall not apply if such target business, vendor or
other person has executed an agreement waiving any claims against the Trust Fund.


 


4. In the event that the Company
does not consummate a Business Combination and must liquidate and its remaining net assets are insufficient to complete such liquidation,
the undersigned Insider agrees to advance such funds necessary to complete such liquidation and agrees not to seek recourse for such expenses.


 


5. (a) During the period ending
180 days after the effective date of the Underwriting Agreement, the undersigned Insider hereby agrees he, she or it shall not, without
the prior written consent of the Representative, (i) sell, offer to sell, contract or agree to sell, hypothecate, pledge, grant any option
to purchase or otherwise dispose of or agree to dispose of, directly or indirectly, or establish or increase a put equivalent position
or liquidate or decrease a call equivalent position within the meaning of Section 16 of the Securities Exchange Act of 1934, as amended
(the “Exchange Act”), and the rules and regulations of the U.S. Securities and Exchange Commission (the “SEC”)
promulgated thereunder, with respect to any Units, shares of Common Stock, Warrants, Rights or any securities convertible into, or exercisable,
or exchangeable for, shares of Common Stock owned by it, him or her, (ii) enter into any swap or other arrangement that transfers to another,
in whole or in part, any of the economic consequences of ownership of any Units, shares of Common Stock, Warrants, Rights or any securities
convertible into, or exercisable, or exchangeable for, shares of Common Stock owned by it, him or her, whether any such transaction is
to be settled by delivery of such securities, in cash or otherwise, or (iii) publicly announce any intention to effect any transaction
specified in clause (i) or (ii). The undersigned Insider acknowledges and agrees that, prior to the effective date of any release or waiver
of the restrictions set forth in this paragraph 5, the Company shall announce the impending release or waiver by press release through
a major news service at least two business days before the effective date of the release or waiver. Any release or waiver granted shall
only be effective two business days after the publication date of such press release. The provisions of this paragraph will not apply
if (i) the release or waiver is effected solely to permit a transfer of securities that is not for consideration and (ii) the transferee
has agreed in writing to be bound by the same terms described in this letter agreement to the extent and for the duration that such terms
remain in effect at the time of the transfer.


 


(b) The undersigned Insider
hereby agrees that none of the Private Units or any shares of Common Stock, Warrants or Rights underlying the Private Units may be sold,
assigned or transferred (except to the Permitted Transferees) until after the consummation of the initial Business Combination. The “Permitted
Transferees” include: (i) transfers among the Insiders, to our officers, directors, advisors and employees, (ii) transfers
to an insider’s affiliates or its members upon its liquidation, (iii) transfers to relatives and trusts for estate planning purposes,
(iv) transfers by virtue of the laws of descent and distribution upon death, (v) transfers pursuant to a qualified domestic relations
order, (vi) private sales made at prices no greater than the price at which the securities were originally purchased or (vii) transfers
to us for cancellation in connection with the consummation of an initial business combination, in each case (except for clause (vii))
where the transferee agrees to the same transfer restrictions, as well as the other applicable restrictions and agreements of the holders
of the insider shares.

7. The undersigned Insider agrees
that until the Company consummates a Business Combination, the undersigned Insider’s Private Units will be subject to the transfer
restrictions described in the Subscription Agreement relating to the undersigned Insider’s Private Units.


 


8. In order to minimize potential
conflicts of interest which may arise from multiple affiliations, the undersigned Insider agrees to present to the Company for its consideration,
prior to presentation to any other person or entity, any suitable opportunity to acquire a target business, until the earlier of the consummation
by the Company of a Business Combination or the liquidation of the Company, subject to any pre-existing fiduciary and contractual obligations
the undersigned Insider might have.


 


9. The undersigned Insider acknowledges
and agrees that prior to entering into a Business Combination with a target business that is affiliated with any Insiders or their affiliates,
including any company that is a portfolio company of, or otherwise affiliated with, or has received financial investment from, an entity
with which any Insider or its affiliates is affiliated, such transaction must be approved by a majority of the Company’s disinterested
independent directors and the Company must obtain an opinion from an independent investment banking firm (or another independent firm
that commonly renders valuation opinions for the type of target business that the Company is seeking to acquire) that such Business Combination
is fair to the Company’s unaffiliated stockholders from a financial point of view.


 


10. Neither the undersigned
Insider, any member of the family of the undersigned Insider, nor any affiliate of the undersigned Insider will be entitled to receive
and will not accept any compensation or other cash payment prior to, or for services rendered in connection with, the consummation of
the Business Combination; provided that the Company shall be allowed to repay working capital loans (the “Working

the foregoing, the undersigned Insider and any affiliate of the undersigned Insider shall be entitled to reimbursement from the Company
for their out-of-pocket expenses incurred in connection with identifying, investigating and consummating a Business Combination.


 


11. Neither the undersigned
Insider, any member of the family of the undersigned Insider, nor any affiliate of the undersigned Insider will be entitled to receive
