Ladies and Gentlemen:


 


Maxpro Capital Acquisition Corp.
(the “Company”), a blank check company formed for the purpose of acquiring one or more businesses or entities (a “Business
Combination”), intends to register its securities under the Securities Act of 1933, as amended (“Securities Act”), in
connection with its initial public offering (“IPO”), pursuant to a registration statement on Form S-1 (“Registration
Statement”).


 


The undersigned hereby commits
that it will purchase 420,275 units of the Company (“Private Units”), each Private Unit consisting of one share of Class A
common stock of the Company, par value $0.0001 per share (the “Class A Common Stock”), and one warrant (the “Warrants”),
with each whole warrant entitling its holder to purchase one (1) share of Class A Common Stock, for a purchase price of $4,202,750
(the “Private Unit Purchase Price”).


 


The undersigned hereby agrees
that it will purchase an additional amount of units of the Company (“Over-Allotment Units”), up to a maximum of 43,875 Over-Allotment
Units, or a maximum purchase price of $438,750 (“Over-Allotment Unit Purchase Price”, together with the Private Unit Purchase
Price, the “Purchase Price”), in the event EF Hutton, division of Benchmark Investments, LLC (“EF Hutton”)
exercises its over-allotment option, such that the amount held in the trust account (as described in the Registration Statement) does
not fall below $10.15 per share for each share of Class A Common Stock sold in the IPO.


 


At least twenty-four (24) hours
prior to the effective date of the Registration Statement, the undersigned will cause the Private Unit Purchase Price to be delivered
to Nelson Mullins Riley & Scarborough LLP (“Nelson Mullins”), counsel for the Company, by wire transfer as set forth
in the instructions attached as Exhibit A to hold in a non-interest bearing account until the Company consummates the IPO.


 


The consummation of the purchase
and issuance of the Private Units shall occur simultaneously with the consummation of the IPO and the consummation of the purchase and
issuance of the Over-Allotment Units shall occur simultaneously with the closing of any exercise of the over-allotment option related
to the IPO. Simultaneously with the consummation of the IPO, Nelson Mullins shall deposit the Private Unit Purchase Price, without interest
or deduction, into the trust fund (“Trust Fund”) established by the Company for the benefit of the Company’s public
shareholders as described in the Registration Statement. If the Company does not complete the IPO within ten (10) days from the date
of this letter, the Private Unit Purchase Price (without interest or deduction) will be returned to the undersigned.


 


Each of the Company, and the
undersigned acknowledges and agrees that Nelson Mullins is serving hereunder solely as a convenience to the parties to facilitate the
purchase of the Private Units and Nelson Mullins’s sole obligation under this letter agreement is to act with respect to holding
and disbursing the Private Unit Purchase Price as described above. Nelson Mullins shall not be liable to the Company, EF Hutton or the
undersigned or any other person or entity in respect of any act or failure to act hereunder or otherwise in connection with performing
its services hereunder unless Nelson Mullins has acted in a manner constituting gross negligence or willful misconduct. The Company and
the undersigned shall indemnify Nelson Mullins against any claim made against it (including reasonable attorney’s fees) by reason
of it acting or failing to act in connection with this letter agreement except as a result of its gross negligence or willful misconduct.
Nelson Mullins may rely and shall be protected in acting or refraining from acting upon any written notice, instruction or request furnished
to it hereunder and believed by it to be genuine and to have been signed or presented by the proper party or parties.


 






     


     


    

 


The Private Units and Over-Allotment
Units will be identical to the units to be sold by the Company in the IPO. Additionally, the undersigned agrees:


 


	 	·	to vote the shares of Class A Common Stock included in the Private Units and Over-Allotment Units in favor of any proposed Business Combination;


 


	 	·	not to propose, or vote in favor of, an amendment to the Company’s Amended and Restated Certificate of Incorporation that would affect the substance or timing of the Company’s obligation to redeem 100% of the Company’s shares of Class A Common Stock sold in the IPO if the Company does not complete an initial Business Combination within 12 months from the closing of the IPO (or up to 18 months from the closing of the IPO if the Company extends the period of time to consummate an initial Business Combination as described in more detail in the prospectus included in the Registration Statement), unless the Company provides the holders of shares of Class A Common Stock sold in the IPO with the opportunity to redeem their shares of Class A Common Stock upon approval of any such amendment at a per-share price, payable in cash, equal to the aggregate amount of the Trust Fund, including interest earned on Trust Fund and not previously released to the Company to pay the Company’s franchise and income taxes, divided by the number of then outstanding shares of Class A Common Stock sold in the IPO;


 


	 	·	not to convert any shares of Class A Common Stock included in the Private Units and Over-Allotment Units into the right to receive cash from the Trust Fund in connection with a shareholder vote to approve either a Business Combination or an amendment to the provisions of the Company’s Amended and Restated Certificate of Incorporation, and not to tender the Private Units and Over-Allotment Units in connection with a tender offer conducted prior to the closing of a Business Combination;


 


	 	·	the undersigned will not participate in any liquidation distribution with respect to the Private Units and Over-Allotment Units (but will participate in liquidation distributions with respect to any units or shares of Class A Common Stock purchased by the undersigned in the IPO or in the open market) if the Company fails to consummate a Business Combination;


 


	 	·	that the Private Units, Over-Allotment Units and underlying securities will not be transferable until after the consummation of a Business Combination except (i) to the Company’s pre-IPO shareholders, or to the Company’s officers, directors, advisors and employees, (ii) transfers to the undersigned’s affiliates or its members upon its liquidation, (iii) to relatives and trusts for estate planning purposes, (iv) by virtue of the laws of descent and distribution upon death, (v) pursuant to a qualified domestic relations order, (vi) by private sales made in connection with the consummation of a Business Combination at prices no greater than the price at which the Private Units were originally purchased or (vii) to the Company for cancellation in connection with the consummation of a Business Combination, in each case (except for clause vii) where the transferee agrees to the terms of the transfer restrictions; and


 


	 	·	the Private Units and Over-Allotment Units will include any additional terms or restrictions as is customary in other similarly structured blank check company offerings or as may be reasonably required by the underwriters in the IPO in order to consummate the IPO, each of which will be set forth in the Registration Statement.


 






     


     


    

 


The undersigned acknowledges and agrees that the
purchaser of the Private Units and Over-Allotment Units will execute agreements in form and substance typical for transactions of this

The undersigned hereby represents
and warrants that:


 


	 	(a)	it has been advised that the Private Units and Over-Allotment Units have not been registered under the Securities Act;

the entire agreement between the undersigned and the Company with respect to the purchase of the Private Units and Over-Allotment Units,
and supersedes all prior and contemporaneous understandings, agreements, representations and warranties, both written and oral, with respect
to the same.
