Re: CFO Appointment


 


Ladies and Gentlemen:


 


This letter (this
 “Letter Agreement”) , dated as of the date hereof and effective as of March 30, 2022, is being delivered
to you in connection with your appointment as Chief Financial Officer of Health Assurance Acquisition Corp., a Delaware corporation
(the “Company”). Reference is made to the Company’s initial public offering (the “Public
Offering”), of 57,500,000 of the Company’s SAILSM securities (including up to 7,500,000
SAILSM securities granted to the underwriter in the Public Offering that may be purchased to cover over-allotments, if
any) (the “SAILSM securities”), each comprised of one share of the Company’s Class A
common stock, par value $0.0001 per share (the “Class A Common Stock”), and one-fourth of one redeemable
warrant. Each whole Warrant (each, a “Warrant”) entitles the holder thereof to purchase one share of Class
A Common Stock at a price of $11.50 per share, subject to adjustment. The SAILSM securities were sold in the Public
Offering pursuant to a registration statement on Form S-1 and a prospectus (the “Prospectus”)
included therein, filed by the Company with the Securities and Exchange Commission (the “Commission”).
Certain capitalized terms used herein are defined in paragraph 9 hereof.


 


For good and valuable consideration, the receipt
and sufficiency of which are hereby acknowledged, the undersigned (the “Insider”), hereby agrees with the Company
as follows:


 


1.                 
The Insider agrees that if the Company seeks stockholder approval of a proposed Business Combination, then in connection with such
proposed Business Combination, it, he shall (i) vote any shares of capital stock owned by him in favor of any proposed Business
Combination and (ii) not redeem any shares of Class A Common Stock owned by him in connection with such stockholder approval. If
the Company seeks to consummate a proposed Business Combination by engaging in a tender offer, the Insider agrees that he will not sell
or tender any shares of Class A Common Stock owned by him in connection therewith.


 


2.                  The
Insider hereby agrees that in the event that the Company fails to consummate a Business Combination within 24 months from the
closing of the Public Offering, or such later period approved by the Company’s stockholders in accordance with the
Company’s amended and restated certificate of incorporation, the Insider shall take all reasonable steps to 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, subject to lawfully available funds therefor, redeem 100% of the Class A Common Stock sold as part
of the SAILSM securities in the Public Offering (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 funds held in
the Trust Account and not previously released to the Company to pay franchise and income taxes (less up to $100,000 of such net
interest to pay dissolution expenses), divided by the number of then outstanding Offering Shares, which redemption will completely
extinguish all Public Stockholders’ rights as stockholders (including the right to receive further liquidation distributions,
if any), subject to applicable law, 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 each case to the Company’s obligations under Delaware law to provide for claims of creditors and other requirements of
applicable law. The Insider agrees to not propose any 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 Offering Shares if
the Company does not complete a Business Combination within 24 months from the closing of the Public Offering or with respect to any
other provisions relating to the rights of holders of our Class A Common Stock, unless the Company provides its public stockholders
with the opportunity to redeem their Offering Shares upon approval of any such amendment 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 funds held in the Trust Account
and not previously released to the Company to pay its franchise and income taxes, divided by the number of then outstanding Offering
Shares.


 






     


     


    

 


The Insider acknowledges that he has no right,
title, interest or claim of any kind in or to any monies held in the Trust Account or any other asset of the Company as a result of any
liquidation of the Company with respect to the Alignment Shares held by it. The Insider hereby
further waives, with respect to any shares of Class A Common Stock held by him, if any, any redemption rights he may have in connection
with the consummation of a Business Combination, including, without limitation, any such rights available in the context of a stockholder
vote (i) to approve such Business Combination or in the context of a tender offer made by the Company to purchase shares of Class A Common
Stock (although the Insider and his affiliates shall be entitled to redemption and liquidation rights with respect to any shares of Class
A Common Stock it or they hold if the Company fails to consummate a Business Combination within 24 months from the date of the closing
of the Public Offering) or (ii) to approve an amendment to the Company’s amended and restated certificate of incorporation to modify
the substance or timing of its obligation to redeem 100% of our public shares if we have not consummated a Business Combination within
24 months (or 27 months, if applicable) from the closing of the initial public offering or with respect to any other material provisions
relating to stockholders’ rights or pre- Business Combination activity.


 


3.                 
The undersigned acknowledges and agrees that prior to entering into a definitive agreement for a Business Combination with a target
company that is affiliated with the undersigned, HAAC Sponsor, LLC, a Delaware limited liability company (the “Sponsor”),
Health Assurance Economy Foundation (the “Foundation”), any director or any other officers 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, which is a member of the Financial Industry Regulatory Authority,
or an independent accounting firm that such Business Combination is fair to the Company’s unaffiliated stockholders from a financial
point of view.


 


4.                  (a)           In
order to minimize potential conflicts of interest that may arise from multiple corporate affiliations, the Insider hereby agrees
that until the earliest of the Company’s initial Business Combination or liquidation, the Insider shall present to the Company
for its consideration, prior to presentation to any other entity, any target candidate that has a fair market value of at least 80%
of the net assets held in the Trust Account (excluding the amount of deferred underwriting discounts held in trust and taxes payable
on the interest earned on the trust account), subject to any existing or future fiduciary or contractual obligations the undersigned
might have.

(b)           The
Insider hereby agrees and acknowledges that: (i) the Company would be irreparably injured in the event of a breach by such Sponsor,
the Foundation or an Insider of his obligations under paragraphs 1, 2, 3, 4(a), 5(a), 5(b) and 7, as applicable, of this Letter Agreement
(ii) monetary damages may not be an adequate remedy for such breach and (iii) the non-breaching party shall be entitled to injunctive
relief, in addition to any other remedy that such party may have in law or in equity, in the event of such breach.


 


5.               
(a)           The Insider agrees that he shall not Transfer any Alignment Shares (or shares
of Class A Common Stock issuable upon conversion thereof) until the earlier of (x) 180 days after the completion of the Company’s
initial Business Combination or (y) the date on which the Company completes a liquidation, merger, capital stock exchange, reorganization
or other similar transaction that results in all of the Company’s stockholders having the right to exchange their shares of Class
A Common Stock for cash, securities or other property (the “Alignment Shares Lock-up Period”).


 


(b)         
The Insider agrees that he shall not Transfer any Private Placement Warrants (and any shares of Class A Common Stock issued upon
conversion or exercise thereof), until 30 days after the completion of the Company’s initial Business Combination (the “Private
Placement Lock-up Period”, and together with the Performance Shares Lock-up Period and the Alignment
Shares Lock-Up Period the “Lock-up Periods”).


 


(c)          Notwithstanding
the provisions set forth in paragraphs 5(a) and (b), Transfers of the Alignment Shares
and Private Placement Warrants (and shares of Class A Common Stock issued or issuable upon the exercise or conversion of the Private
Placement Warrants and the Alignment Shares and that are held by the Insider or any of
his permitted transferees (that have complied with this paragraph 5(c)), are permitted (a) to the Company’s officers or
directors, any affiliates or family members of any of the Company’s officers or directors, any member of the Initial
Stockholders, any affiliates or family members of any member of the Initial Stockholders, any members or partners of the
Company’s initial, or their affiliates, any affiliates of the Initial Stockholders, or any employees of such affiliates;
(b) in the case of an individual, by gift to a member of one of the individual’s immediate family or to a trust, the
beneficiary of which is a member of the individual’s immediate family, an affiliate of such person or to a charitable
organization; (c) in the case of an individual, by virtue of laws of descent and distribution upon death of the individual;
(d) in the case of an individual, pursuant to a qualified domestic relations order; (e) by private sales or transfers made
in connection with the consummation of an initial Business Combination at prices no greater than the price at which the private
placement warrants or shares of Class A common stock, as applicable, were originally purchased; (f) by virtue of the
Initial Stockholders’ organizational documents upon liquidation or dissolution of the Initial Stockholders; (g) to the

(h) in the event of the Company’s liquidation prior to the completion of the Company’s initial Business

Class A common stock for cash, securities or other property subsequent to the Company’s completion of the an initial
Business Combination; provided, however, that in the case of clauses (a) through (e) these permitted transferees must enter
