		Re:	Sponsor Agreement



 


Ladies and Gentlemen:


 


This
letter (this “Sponsor Agreement”) is being delivered to you in connection with that certain Agreement and Plan
of Merger, dated as of the date hereof, by and among Churchill Capital Corp III, a Delaware corporation (“Acquiror”),
Polaris Investment Holdings, L.P., a Delaware limited partnership (“Holdings”), Polaris Parent Corp., a Delaware
corporation (“Parent”, and collectively with Holdings, the “Company”) and the other parties
thereto (the “Merger Agreement”) and hereby amends and restates in its entirety that certain letter, dated
February 13, 2020, from Churchill Sponsor III LLC (the “Sponsor”) and each of the undersigned individuals,
each of whom is a member of Acquiror’s board of directors and/or management team (each, an “Insider”
and collectively, the “Insiders”) to Acquiror (the “Prior Letter Agreement”). Certain capitalized
terms used herein are defined in paragraph 10 hereof. Capitalized terms used but not otherwise defined herein shall have the respective
meanings ascribed to such terms in the Merger Agreement.


 


In
order to induce the Company and Acquiror to enter into the Merger Agreement and for other good and valuable consideration, the
receipt and sufficiency of which are hereby acknowledged, Sponsor and each of the Insiders, hereby severally (and not jointly
and severally) agrees with Acquiror and, at all times prior to any valid termination of the Merger Agreement, the Company as follows:


 






     


     


    

 


1.            The
Sponsor and each Insider hereby unconditionally and irrevocably agrees: (i) that at
any duly called meeting of the stockholders of Acquiror (or any adjournment or postponement thereof), and in any action by written
consent of the stockholders of Acquiror requested by Acquiror’s board of directors or undertaken as contemplated by the
Transactions, the Sponsor and each such Insider shall, if a meeting is held, appear at the meeting, in person or by proxy, or
otherwise cause all of its, his or her shares of Capital Stock to be counted as present thereat for purposes of establishing a
quorum, and it shall vote or consent (or cause to be voted or consented), in person or by proxy, all of its, his or her shares
of Capital Stock (a) in favor of the adoption of the Merger Agreement and approval of the Transactions (and any actions required
in furtherance thereof), (b) against any action, proposal, transaction or agreement that would reasonably be expected to
result in a breach of any representation, warranty, covenant, obligation or agreement of Acquiror contained in the Merger Agreement,
(c) in favor of any other proposals set forth in Acquiror’s proxy statement to be filed by Acquiror with the SEC relating
to the Transactions (including any proxy supplements thereto, the “Proxy Statement”), (d) for any proposal
to adjourn or postpone the applicable stockholder meeting to a later date if (and only if) (1) there are not sufficient votes
for approval of the Merger Agreement and any other proposals related thereto as set forth in the Proxy Statement on the dates
on which such meetings are held or (2) the closing condition in Section 10.03(c) of the Merger Agreement has not
been satisfied, and (e) except as set forth in the Proxy Statement, against the following actions or proposals: (1) any
Business Combination Proposal or any proposal in opposition to approval of the Merger Agreement or in competition with or inconsistent
with the Merger Agreement; and (2) (A) any change in the present capitalization of Acquiror or any amendment of the
Certificate of Incorporation, except to the extent expressly contemplated by the Merger Agreement, (B) any liquidation, dissolution
or other change in Acquiror’s corporate structure or business, (C) any action, proposal, transaction or agreement that
would result in a breach in any material respect of any covenant, representation or warranty or other obligation or agreement
of the Sponsor or such Insider under this Sponsor Agreement, or (D) any other action or proposal involving Acquiror or any
of its subsidiaries that is intended, or would reasonably be expected, to prevent, impede, interfere with, delay, postpone or
adversely affect the Transactions and (ii) not to redeem, elect to redeem or tender or submit any of its shares of Common
Stock owned by it, him or her for redemption in connection with such stockholder approval or proposed Business Combination, or
in connection with any vote to amend Acquiror’s Charter (as defined below). Prior to any valid termination of the Merger
Agreement, (x) the Sponsor and each Insider shall take, or cause to be taken, all actions and to do, or cause to be done,
all things reasonably necessary under applicable Laws to consummate the Merger and the other transactions contemplated by the
Merger Agreement and on the terms and subject to the conditions set forth therein, and (y) the Sponsor and each Insider shall
be bound by and comply with Sections 9.03 (Exclusivity) and 9.05 (Confidentiality; Publicity) of the Merger Agreement (and any
relevant definitions contained in any such Sections) as if such Person were a signatory to the Merger Agreement with respect to
such provisions. If Acquiror seeks to consummate a proposed Business Combination by engaging in a tender offer, the Sponsor and
each Insider agrees that it, he or she will not sell or tender any shares of Capital Stock owned by it, him or her in connection
therewith. The obligations of the Sponsor and the Insiders specified in this paragraph 1 shall apply whether or not the Mergers,
any of the Transactions or any action described above is recommend by Acquiror’s board of directors.


 






     2


    


    

 


2.            The
Sponsor and each Insider hereby agrees that in the event that
Acquiror fails to consummate a Business Combination by February 19, 2022 (or May 19, 2022 if Acquiror has executed
a letter of intent, agreement in principle or definitive agreement for an initial business combination
before February 19, 2022), or such later period approved by Acquiror’s stockholders in accordance with Acquiror’s
amended and restated certificate of incorporation (the “Charter”), the Sponsor and each Insider shall take
all reasonable steps to cause Acquiror 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 Common Stock sold as part of the Units 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 (net of amounts
withdrawn to fund Acquiror’s working capital requirements, subject to an annual limit of $1,000,000, and/or to pay Acquiror’s
taxes (“Permitted Withdrawals”)) and less up to $100,000 of 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 liquidating distributions, if any), subject to applicable law,
and (iii) as promptly as reasonably possible following such redemption, subject to the approval of Acquiror’s remaining
stockholders and Acquiror’s board of directors, dissolve and liquidate, subject in each case to Acquiror’s obligations
under Delaware law to provide for claims of creditors and other requirements of applicable law. The Sponsor and each Insider agree
to not propose any amendment to the Charter that would modify the substance or timing of Acquiror’s obligation to redeem
100% of the Offering Shares if Acquiror does not complete a Business Combination within the required time period set forth in
the Charter or with respect to any other material provisions relating to stockholders’ rights or pre-initial business combination
activity, unless Acquiror 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 (net of Permitted Withdrawals), divided by the number of then outstanding Offering Shares.


 


The
Sponsor and each Insider acknowledges that it, he or she 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 Acquiror as a result of any liquidation of Acquiror with respect to the Founder
Shares held by it, him or her. The Sponsor and each Insider hereby further waive, with respect to any shares of Common Stock held
by it, him or her, if any, any redemption rights it, he or she 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 to approve such Business Combination
or in the context of a tender offer made by Acquiror to purchase shares of Common Stock (although the Sponsor, the Insiders and
their respective Affiliates shall be entitled to redemption and liquidation rights with respect to any Offering Shares it or they
hold if Acquiror fails to consummate a Business Combination within the time period set forth in the Charter).


 


3.            Without
limiting their obligations under paragraph 6 below or pursuant to the Investor Rights Agreement, during the period commencing
on the date hereof and ending on the earlier of (a) the valid termination of the Merger Agreement or (b) the Closing,
the Sponsor and each Insider shall not, without the prior written consent of the Company, Transfer any Units, shares of Capital
Stock, warrants (each, a “Warrant”) to purchase shares of Common Stock or any securities convertible into,
or exercisable, or exchangeable for, shares of Common Stock owned by it, him or her. In the event that (i) any shares of
Capital Stock, Warrants or other equity securities of Acquiror are issued to the Sponsor or any Insider after the date hereof
pursuant to any stock dividend, stock split, recapitalization, reclassification, combination or exchange of shares of Capital
Stock of, on or affecting the shares of Capital Stock owned by the Sponsor or any Insider or otherwise, (ii) the Sponsor
or any Insider purchases or otherwise acquires beneficial ownership of any shares of Capital Stock, Warrants or other equity securities
of Acquiror after the date hereof or (iii) the Sponsor or any Insider acquires the right to vote or share in the voting of
any shares of Capital Stock, Warrants or other equity securities of Acquiror after the date hereof (such shares of Capital Stock,
Warrants or other equity securities of Acquiror described in clauses (i), (ii) and (iii), the “New Shares”),
then such New Shares acquired or purchased by the Sponsor or any Insider shall be subject to the terms of this paragraph 3 and
paragraph 1 above to the same extent as if they constituted the Capital Stock or Warrants owned by the Sponsor or any Insider
as of the date hereof.


 






     3


    


    

 


4.            In
the event of the liquidation of the Trust Account, the Sponsor (which for purposes of clarification shall
not extend to any other shareholders, members or managers of the Sponsor or any other Insider) agrees to indemnify and hold harmless
Acquiror against any and all loss, liability, claim, 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) to which Acquiror may become subject as a result of any claim by (i) any third party
for services rendered or products sold to Acquiror or (ii) any prospective target business with which Acquiror has entered
into a letter of intent, confidentiality or other similar agreement for a Business Combination (a “Target”);
provided, however, that such indemnification of Acquiror by the Sponsor (x) shall apply only to the extent
necessary to ensure that such claims by a third party or a Target do not reduce the amount of funds in the Trust Account to below
the lesser of (i) $10.00 per Offering Share or (ii) the
actual amount per Offering Share held in the Trust Account as of the date of the liquidation of the Trust Account, if less than
$10.00 per Offering Share is then held in the Trust Account due to reductions in the value of the trust assets less Permitted
Withdrawals, (y) shall not apply to any claims by a third party (including a Target) that executed a waiver of any and all
rights to the monies held in the Trust Account (whether or not such waiver is enforceable) and (z) shall not apply to any
claims under Acquiror’s indemnity of Citigroup Global Markets Inc. (the “Representative”) against certain
liabilities, including liabilities under the Securities Act of 1933, as amended. The Sponsor shall have the right to defend against
any such claim with counsel of its choice reasonably satisfactory to Acquiror if, within 15 days following written receipt of
notice of the claim to the Sponsor, the Sponsor notifies Acquiror in writing that it shall undertake such defense. For the avoidance
of doubt, none of Acquiror’s officers or directors will indemnify Acquiror for claims by third parties, including, without
limitation, claims by vendors and prospective target businesses.


 


5.            The
Sponsor and each Insider hereby agrees and acknowledges that: (i) the
Representative, Acquiror and, prior to any valid termination of the Merger Agreement, the Company would be irreparably injured
in the event of a breach by such Sponsor or an Insider of its, his or her obligations under paragraphs 1, 2, 3, 4, 6(a), 6(b),
6(c), 6(d), 8 and 12, as applicable, of this Sponsor Agreement (with respect to the Representative, only such provisions as were
contained in the Prior 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.


 


6.             (a)           In
the event that (i) the Closing does not occur for any reason (including, without limitation, as a result of the valid
termination of the Merger Agreement), the Sponsor and each Insider agrees that it, he or she shall not Transfer any Founder
Shares (or shares of Common Stock issuable upon conversion thereof) until the earlier of (A) one year after the
completion of Acquiror’s initial Business Combination or (B) subsequent to the Business Combination, (x) if
the closing price of the Common Stock equals or exceeds $12.00 per share (as adjusted for stock splits, stock dividends,
reorganizations, recapitalizations and the like) for any 20 trading days within any 30-trading day period commencing at least
150 days after Acquiror’s initial Business Combination or (y) the date on which Acquiror completes a liquidation,
merger, capital stock exchange, reorganization or other similar transaction that results in all of Acquiror’s
stockholders having the right to exchange their shares of Common Stock for cash, securities or other property and
(ii) the Closing does occur, the Sponsor and each Insider agrees that it, he or she shall not Transfer (A) any
Founder Shares or any other Capital Stock of Acquiror owned by such Person as of the Closing Date (after giving effect to the
consummation of the Transactions) or the Private Placement Warrants identified on Annex A as “Locked-Up
Warrants”, or (B) any shares of Common Stock issued or issuable upon the exercise of such Private Placement
Warrants identified on Annex A as “Locked-Up Warrants” (clauses (A) and (B), collectively, the
 “Locked-Up Acquiror Securities”) until the eighteen month anniversary of the Closing Date (such period,
the “Founder Shares Lock-up Period”).


 






     4


    


    

 


(b)           In
the event that the Closing does not occur for any reason (including, without limitation, as a result of the valid termination
of the Merger Agreement), the Sponsor and each Insider agrees that it, he or she shall not Transfer any Private Placement Warrants
(or shares of Common Stock issued or issuable upon the exercise of the Private Placement Warrants) until 30 days after the completion
of a Business Combination (the “Private Placement Warrants Lock-up Period”, and together with the Founder Shares
Lock-up Period, the “Lock-up Periods”).


 


(c)           Notwithstanding
the provisions set forth in paragraphs 3 and 6(a) and (b), but subject to the provisions set forth in paragraph 6(d), (i) upon
the valid termination of the Merger Agreement, the following Transfers of the Founder Shares, the Private Placement Warrants and
shares of Common Stock issued or issuable upon the exercise or conversion of the Private Placement Warrants or the Founder Shares
that are held by the Sponsor, any Insider or any of their permitted transferees (that have complied with this paragraph 6(c)),
are permitted: (A) to Acquiror’s officers or directors, any affiliates or family members of any of Acquiror’s
officers or directors, any members of the Sponsor, or any affiliates of the Sponsor; (B) in the case of an individual,
transfers by gift to a member of the individual’s immediate family, to a trust, the beneficiary of which is a member of
the individual’s immediate family or an affiliate of such person, or to a charitable organization; (C) in the
case of an individual, transfers by virtue of laws of descent and distribution upon death of the individual; (D) in
the case of an individual, transfers pursuant to a qualified domestic relations order; (E) transfers by private sales
or transfers made in connection with the consummation of a Business Combination at prices no greater than the price at which the

of an initial Business Combination; (G) transfers by virtue of the laws of the State of Delaware or the Sponsor’s
limited liability company agreement upon dissolution of the Sponsor; (H) in the event of Acquiror’s completion
of a liquidation, merger, stock exchange, reorganization or other similar transaction which results in all of Acquiror’s
public stockholders having the right to exchange their shares of Common Stock for cash, securities or other property subsequent
to the completion of the initial business combination; (I) to a nominee or custodian of a person or entity to whom a
disposition or transfer would be permissible under clauses (A) through (H) above; provided, however,
that in the case of clauses (A) through (E) and (I), these permitted transferees must enter into a written agreement
with Acquiror agreeing to be bound by the transfer restrictions herein and the other restrictions contained in this Sponsor Agreement
(including provisions relating to voting, the Trust Account and liquidating distributions) and (ii) during the period commencing
on the date hereof and ending on the earlier of (x) the expiration of the Lock-up Periods and (y) the date of any valid
termination of the Merger Agreement, the following, Transfers of the Founder Shares, the Private Placement Warrants identified
on Annex A as “Locked-Up Warrants”, shares of Common Stock issued or issuable upon the exercise or conversion

that to the extent such members have obligations pursuant to this Sponsor Agreement, such members shall confirm in writing to
Acquiror and the Company that the securities so distributed to them will continue to be subject to such obligations; provided,
further, that any other permitted transferees must enter into a written agreement with Acquiror or the Company agreeing
to be bound by the transfer restrictions herein.


 






     5


    


    

 


(d)           Vesting
Provisions. The Sponsor agrees that, as of the Closing, all of (A) the Founder Shares or shares of Common Stock issued
or issuable upon the exercise or conversion of the Founder Shares as identified on Annex A as “Vesting Shares”
and (B) the Private Placement Warrants as identified on Annex A as being “Vesting Warrants,” in each case,
as of the Closing shall be unvested and shall be subject to the vesting and forfeiture provisions set forth in this paragraph
6(d). The Sponsor agrees that it shall not (and will cause its Affiliates not to) Transfer any unvested Founder Shares or shares
of Common Stock issued or issuable upon the exercise or conversion of the unvested Founder Shares or any unvested Private Placement
Warrants prior to the later of (x) the expiration of the Founder Shares Lock-up Period and (y) the date such Founder
Shares, shares of Common Stock or Private Placement Warrants become vested pursuant to this paragraph 6(d). For the avoidance
of doubt, it is acknowledged and agreed that any Founder Shares, shares of Common Stock issued or issuable upon the exercise or
conversion of the Founder Shares and Private Placement Warrants that are not identified on Annex A as being either “Vesting
Shares” or “Vesting Warrants” shall not be subject to the provisions of this paragraph 6(d).


 


(i)            Vesting
of Shares. The unvested Founder Shares or shares of Common Stock issued or issuable upon the exercise or conversion of the
unvested Founder Shares Beneficially Owned by Sponsor and identified on Annex A as “Vesting Shares” shall vest
at such time as a $12.50 Stock Price Level is achieved on or before the date that is five years after the Closing Date. Unvested
Founder Shares (or shares of Common Stock) that do not vest in accordance with this paragraph 6(d)(i) on or before the date
that is five years after the Closing Date will be forfeited immediately following the five-year anniversary of the Closing Date.


 


(ii)           Vesting
of Private Placement Warrants. The unvested Private Placement Warrants Beneficially Owned by Sponsor and identified on Annex
A as “Vesting Warrants” shall vest at such time as a $12.50 Stock Price Level is achieved on or before the date
that is five years after the Closing Date. Unvested Private Placement Warrants that do not vest in accordance with this paragraph
6(d)(ii) on or before the date that is five years after the Closing Date will be forfeited immediately following the five-year
anniversary of the Closing Date.


 






     6


    


    

 


(iii)          Acceleration
of Vesting upon an Acquiror Sale. In the event of an Acquiror Sale (as defined below) prior to the fifth anniversary of the
Closing Date (or prior to the sixth anniversary of the Closing Date for purposes of paragraph 6(d)(iii)(4)), the vesting of unvested
Founder Shares, shares of Common Stock issued or issuable upon the exercise or conversion of the unvested Founder Shares and the
unvested Private Placement Warrants shall be accelerated or the unvested Founder Shares, shares of Common Stock or Private Placement
Warrants will be forfeited, as follows:


 


(1)           With
respect to the unvested Founder Shares (or shares of Common Stock) and Private Placement Warrants that were eligible to vest pursuant
to paragraph 6(d)(i) or 6(d)(ii), as the case may be, if such Acquiror Sale occurs on or before the date that is five years
after the Closing Date, then (i) such Founder Shares (or shares of Common Stock) and Private Placement Warrants will fully
vest as of immediately prior to the closing of such Acquiror Sale only if the per share price of the Common Stock paid or implied
in such Acquiror Sale equals or exceeds $12.50, (ii) no portion of such Founder Shares (or shares of Common Stock) and Private
Placement Warrants will vest in connection with such Acquiror Sale if the per share price of the Common Stock paid or implied
in such Acquiror Sale is less than $10.00, and (iii) if the per share price of the Common Stock paid or implied in such Acquiror
Sale is equal to or greater than $10.00 and less than $12.50, the number of such Founder Shares (or shares of Common Stock) and
Private Placement Warrants that will vest in connection with such Acquiror Sale will be determined based on linear interpolation
between such share price levels (e.g., 50% of such Founder Shares (or shares of Common Stock) and Private Placement Warrants
will vest if the per share price of the Common Stock paid or implied in such Acquiror Sale is $11.25), and no remaining portion
of such Founder Shares (or shares of Common Stock) and Private Placement Warrants will vest in connection with such Acquiror Sale.


 


(2)           Unvested
Founder Shares (or shares of Common Stock) and Private Placement Warrants that do not vest in accordance with this paragraph 6(d)(iii) upon
the occurrence of an Acquiror Sale will be forfeited immediately prior to the closing of such Acquiror Sale and in accordance
with paragraph 6(d)(iv).


 


(3)           For
purposes of this paragraph 6(d)(iii), “Acquiror Sale” means (A) a purchase, sale, exchange, business combination
or other transaction (including a merger or consolidation of Acquiror with or into any other corporation or other entity) in which
the equity securities of Acquiror, its successor or the surviving entity of such business combination or other transaction are
not registered under the Securities Exchange Act or 1934, as amended (the “Exchange Act”) or listed or quoted
for trading on a national securities exchange or (B) a sale, lease, exchange or other transfer in one transaction or a series
of related transactions of all or substantially all of Acquiror’s assets to a third party that is not an Affiliate of the
Sponsor (or a group of third parties that are not Affiliates of the Sponsor). For avoidance of doubt, following a transaction
or business combination that is not an “Acquiror Sale” hereunder, including a transaction or business combination
in which the equity securities of the surviving entity of such business combination or other transaction are registered under
the Exchange Act and listed or quoted for trading on a national securities exchange, the equitable adjustment provisions of paragraph
21 shall apply, including, without limitation, to performance vesting criteria.


 






     7


    


    

 


(4)           Holders
of Founder Shares or shares of Common Stock subject to the vesting provisions of this paragraph 6(d) shall be entitled to
vote such Founder Shares or shares of Common Stock and receive dividends and other distributions with respect to such Founder
Shares or shares of Common Stock prior to vesting; provided, that dividends and other distributions with respect to Founder
Shares or shares of Common Stock that are subject to vesting pursuant to paragraph 6(d)(i) shall be set aside by Acquiror
and shall only be paid to such holders upon the vesting of such Founder Shares or shares of Common Stock issuable upon the conversion
of the Founder Shares (if at all); for the avoidance of doubt, such dividends and other distributions shall be paid only on the
portion of the unvested Founder Shares or shares of Common Stock that vest.


 


(iv)          Forfeiture.


 


(1)           Unvested
Founder Shares or shares of Common Stock that are forfeited pursuant to paragraph 6(d)(i) or 6(d)(iii) shall be transferred
by Sponsor to Acquiror, without any consideration for such Transfer, and cancelled.


 


(2)           Unvested
Private Placement Warrants that are forfeited pursuant to paragraph 6(d)(ii) or 6(d)(iii) shall be transferred by Sponsor
to Acquiror, without any consideration for such Transfer, and cancelled.


 


(v)           Stock
Price Level. For purposes of this paragraph 6(d), the applicable “Stock Price Level” will be considered
achieved only when the last reported sale price per share of Common Stock on the New York Stock Exchange, or such other securities
exchange where the Common Stock is listed or quoted, equals or exceeds the applicable threshold for any 40 trading days during
a 60 consecutive trading day period, which 60 consecutive trading day period will not commence until the first anniversary of
the Closing Date. The Stock Price Levels (and the share price levels in an Acquiror Sale in paragraph 6(d)(iii)) will be equitably
adjusted on account of any stock split, reverse stock split or similar equity restructuring transaction.


 


(vi)          Waiver
of Conversion Ratio Adjustment.


 


(1)           (A) Section 4.3(b)(i) of
the Charter provides that each share of Class B Common Stock shall automatically convert into one share of Common Stock (the
 “Initial Conversion Ratio”) at the time of the Business Combination, and (B) Section 4.3(b)(ii) of
the Charter provides that the Initial Conversion Ratio shall be adjusted (the “Adjustment”) in the event that
additional shares of Common Stock are issued in excess of the amounts offered in Acquiror’s initial public offering of securities
such that the Sponsor and the Insiders shall continue to own 25% of the issued and outstanding shares of Capital Stock after giving
effect to such issuance.


 


(2)           As
of and conditioned upon the Closing, the Sponsor and each Insider hereby irrevocably relinquishes and waives any and all rights
the Sponsor and each Insider has or will have under Section 4.3(b)(ii) of the Charter to receive shares of Common Stock
in excess of the number issuable at the Initial Conversion Ratio upon conversion the existing Class B Common Stock held by
him, her or it, as applicable, in connection with the Closing as a result of any Adjustment, and, as a result, the shares of Class B
Common Stock shall convert into shares of Common Stock (or such equivalent security) at Closing on a one-for-one basis.


 






     8


    


    

 


7.            The
Sponsor and each Insider represents and warrants that it, he or she has never been suspended or expelled
from membership in any securities or commodities exchange or association or had a securities or commodities license or registration
denied, suspended or revoked. Each Insider’s biographical information furnished to Acquiror (including any such information
included in the Prospectus) is true and accurate in all respects and does not omit any material information with respect to the
Insider’s background. The Sponsor and each Insider represents and warrants that: it, he or she is not subject to or a respondent
in any legal action for, any injunction, cease-and-desist order or order or stipulation to desist or refrain from any act or practice
relating to the offering of securities in any jurisdiction; it, he or she has never been convicted of, or pleaded guilty to, any
crime (i) involving fraud, (ii) relating to any financial transaction or handling of funds of another person, or (iii) pertaining
to any dealings in any securities and it, he or she is not currently a defendant in any such criminal proceeding.


 


8.             Except
as disclosed in the Prospectus or on Schedule 6.07 (Brokers’ Fees) of the Merger Agreement, neither the Sponsor nor any
Insider nor any affiliate of the Sponsor or any Insider, nor any director
or officer of Acquiror, shall receive from Acquiror any finder’s fee, reimbursement, consulting fee, monies in respect of
any repayment of a loan or other compensation prior to, or in connection with any services rendered in order to effectuate the
consummation of Acquiror’s initial Business Combination (regardless of the type of transaction that it is), other than the
following, none of which will be made from the proceeds held in the Trust Account prior to the completion of the initial Business
Combination and each of which shall, as of and in connection with the Closing, be paid off in full and no further liabilities
or obligations in respect thereof shall be due and owing by Acquiror or the Company or any of its Subsidiaries from and after
the Closing: repayment of a loan and advances of up to $600,000 made to Acquiror by the Sponsor to cover expenses related to the
organization of Acquiror and the Public Offering; payment to the Klein Group, LLC pursuant to that certain Engagement Letter,
dated as of July 12, 2020; payment to M. Klein Associates, Inc.
for office space and related support services for a total of $50,000 per month; reimbursement for any reasonable out-of-pocket
expenses related to identifying, investigating and consummating an initial Business Combination; and repayment of loans, if any,
and on such terms as to be determined by Acquiror from time to time, made by the Sponsor or certain of Acquiror’s officers
and directors to finance transaction costs in connection with an intended initial Business Combination, provided, that, if Acquiror
does not consummate an initial Business Combination, a portion of the working capital held outside the Trust Account may be used
by Acquiror to repay such loaned amounts so long as no proceeds from the Trust Account are used for such repayment. Up to $1,500,000
