Re: Initial Public Offering

Gentlemen: 

This letter is being delivered to you in accordance with the Underwriting Agreement (the “Underwriting Agreement”) entered into by and between Proficient Alpha Acquisition Corp., a Nevada corporation (the “Company”), and I-Bankers Securities, Inc., as representative (the “Representative”) of the several Underwriters named in Schedule I 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 the Company’s common stock, par value $0.001 per share (the “Common Stock”), one warrant exercisable for one share of Common Stock (each, a “Warrant”) and one right to receive one-tenth of one share of Common Stock (each, a “Right”). Certain capitalized terms used herein are defined in paragraph 12 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, and for other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the undersigned hereby agrees with the Company as follows: 

	1.	If the Company solicits approval of its stockholders of a Business Combination, each of the undersigned will vote all shares of Common Stock and Founder’s Common Stock beneficially owned by it, whether acquired before, in or after the IPO, in favor of such Business Combination.
	2.	In the event that the Company fails to consummate a Business Combination within the time period set forth in the Company’s Articles of Incorporation, as the same may be amended from time to time, each of the undersigned will, as promptly as possible, cause the Company to (i) cease all operations except for the purpose of winding up, (ii) as promptly as reasonably possible, but not more than 10 business days thereafter, redeem the Common Stock sold as part of the Units in the IPO (the “Offering Shares”), at a per-share price, payable in cash, equal to the aggregate amount then on deposit in the Trust Account, including interest earned on the Trust Account net of interest that may be used by the Company to pay its taxes payable and for dissolution expenses, divided by the number of then outstanding public shares, which redemption will completely extinguish public stockholders’ rights as stockholders (including the right to receive further liquidation distributions, if any), and (iii) as promptly as reasonably possible following such redemption, subject to the approval of the Company’s remaining stockholders and the Company’s board of directors, dissolve and liquidate, subject in the cases of clauses (ii) and (iii) to the Company’s obligations under Nevada law to provide for claims of creditors and other requirements of applicable law. The undersigned hereby waives any and all right, title, interest or claim of any kind the undersigned may have in the future in or to any distribution of the Trust Account and any remaining net assets of the Company as a result of, or arising out of, any contracts or agreements with the Company and will not seek recourse against the Trust Account for any reason whatsoever.
	3.	Each of the undersigned acknowledges and agrees that prior to entering into a Business Combination with a target business that is affiliated with any Insiders of the Company or their affiliates, 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 entity that commonly renders valuation opinions on the type of target business the Company is seeking to acquire, that such Business Combination is fair to the Company’s unaffiliated stockholders from a financial point of view.
