FORM
OF WARRANT AGREEMENT

 

between

 

YELLOWSTONE
ACQUISITION COMPANY

 

and

 

CONTINENTAL
STOCK TRANSFER & TRUST COMPANY

 

Dated
as of [●], 2020

 

THIS
WARRANT AGREEMENT (this “Agreement”), dated as of [●], 2020, is by and between Yellowstone Acquisition Company,
a Delaware corporation (the “Company”), and Continental Stock Transfer & Trust Company, a New York limited purpose
trust company, as warrant agent (the “Warrant Agent”, also referred to herein as the “Transfer Agent”).

 

WHEREAS,
on [●], 2020, the Company entered into that certain Private Placement Warrants Purchase Agreement with BOC Yellowstone LLC,
a Delaware limited liability company (the “Sponsor”), pursuant to which the Sponsor will purchase an aggregate of
6,000,000 warrants (or 6,600,000 warrants if the Over-allotment Option (as defined below) in connection with the Offering (as
defined below) is exercised in full) simultaneously with the closing of the Offering (and the closing of the Over-allotment Option,
if applicable) bearing the legend set forth in Exhibit B hereto (the “Private Placement Warrants”) at
a purchase price of $1.00

 

WHEREAS,
in order to finance the Company’s transaction costs in connection with an intended initial Business Combination (as defined
below), the Sponsor or an affiliate of the Sponsor or certain of the Company’s officers and directors may loan to the Company
funds, of which up to $1,500,000 of such loans may be convertible into up to an additional 1,000,000 Private Placement Warrants
at a price of $1.50 per warrant; and

 

WHEREAS,
the Company is engaged in an initial public offering (the “Offering”) of units of the Company’s equity securities,
each such unit comprised of one share of Common Stock (as defined below) and one-half of one Public Warrant (as defined below)
(the “Units”) and, in connection therewith, has determined to issue and deliver up to 8,625,000 warrants (including
up to 1,125,000 warrants subject to the Over-allotment Option) to public investors in the Offering (the “Public Warrants”
and, together with the Private Placement Warrants, the “Warrants”).  Each whole Warrant entitles the holder
thereof to purchase one whole share of Class A common stock of the Company, par value $0.0001 per share (“Common Stock”),
for $11.50 per share, subject to adjustment as described herein; and

 

WHEREAS,
the Company has filed with the Securities and Exchange Commission (the “Commission”) a registration statement on Form
S-1 (File No. 333-249035) (the “Registration Statement”) and prospectus (the “Prospectus”), for the
registration, under the Securities Act of 1933, as amended (the “Securities Act”), of the Units, the Public Warrants
and the Common Stock included in the Units; and

 

     

     

    

 

WHEREAS,
the Company desires the Warrant Agent to act on behalf of the Company, and the Warrant Agent is willing to so act, in connection
with the issuance, registration, transfer, exchange, redemption and exercise of the Warrants; and

 

WHEREAS,
the Company desires to provide for the form and provisions of the Warrants, the terms upon which they shall be issued and exercised,
and the respective rights, limitation of rights, and immunities of the Company, the Warrant Agent, and the holders of the Warrants;
and

 

WHEREAS,
all acts and things have been done and performed which are necessary to make the Warrants, when executed on behalf of the Company
and countersigned by or on behalf of the Warrant Agent, as provided herein, the valid, binding and legal obligations of the Company,
and to authorize the execution and delivery of this Agreement.

 

NOW,
THEREFORE, in consideration of the mutual agreements herein contained, the parties hereto agree as follows:

 

1.
Appointment of Warrant Agent.  The Company hereby appoints the Warrant Agent to act as agent for the Company
for the Warrants, and the Warrant Agent hereby accepts such appointment and agrees to perform the same in accordance with the
terms and conditions set forth in this Agreement.

 

2.
Warrants.

 

2.1.
Form of Warrant.  Each Warrant shall be issued in registered form only.

 

2.2.
Effect of Countersignature.  If a physical certificate is issued, unless and until countersigned by the Warrant
Agent pursuant to this Agreement, a Warrant shall be invalid and of no effect and may not be exercised by the holder thereof.

 

2.3.
Registration.

 

2.3.1.
Warrant Register.  The Warrant Agent shall maintain books (the “Warrant Register”), for the registration
of original issuance and the registration of transfer of the Warrants.  Upon the initial issuance of the Warrants, the
Warrant Agent shall issue and register the Warrants in the names of the respective holders thereof in such denominations and otherwise
in accordance with instructions delivered to the Warrant Agent by the Company.  Ownership of beneficial interests in
the Public Warrants shall be shown on, and the transfer of such ownership shall be effected through, records maintained by institutions
that have accounts with the Depository Trust Company (the “Depositary”) (such institution, with respect to a Warrant
in its account, a “Participant”).  If the Depositary subsequently ceases to make its book-entry settlement
system available for the Public Warrants, the Company may instruct the Warrant Agent regarding making other arrangements for book-entry
settlement.  In the event that the Public Warrants are not eligible for, or it is no longer necessary to have the Public
Warrants available in, book-entry form, the Warrant Agent shall provide written instructions to the Depositary to deliver to the
Warrant Agent for cancellation each book-entry Public Warrant, and the Company shall instruct the Warrant Agent to deliver to
the Depositary definitive certificates in physical form evidencing such Warrants which shall be in the form annexed hereto as
Exhibit A.

 

    	 	2	 

     

    

 

Physical
certificates, if issued, shall be signed by, or bear the facsimile signature of, the Chairman of the Board, Chief Executive Officer,
Chief Financial Officer, Secretary or other principal officer of the Company.  In the event the person whose facsimile
signature has been placed upon any Warrant shall have ceased to serve in the capacity in which such person signed the Warrant
before such Warrant is issued, it may be issued with the same effect as if he or she had not ceased to be such at the date of
issuance.

 

2.3.2.
Registered Holder.  Prior to due presentment for registration of transfer of any Warrant, the Company and the
Warrant Agent may deem and treat the person in whose name such Warrant is registered in the Warrant Register (the “Registered
Holder”) as the absolute owner of such Warrant and of each Warrant represented thereby (notwithstanding any notation of
ownership or other writing on any physical certificate made by anyone other than the Company or the Warrant Agent), for the purpose
of any exercise thereof, and for all other purposes, and neither the Company nor the Warrant Agent shall be affected by any notice
to the contrary.

 

2.4.
Detachability of Warrants.  The Common Stock and Public Warrants comprising the Units shall begin separate trading
on the 52nd day following the date of the Prospectus or, if such 52nd day is not on a day, other than a Saturday, Sunday or federal
holiday, on which banks in New York City are generally open for normal business (a “Business Day”), then on the immediately
succeeding Business Day following such date, or earlier (the “Detachment Date”) with the consent of Wells Fargo Securities,
LLC, as representative of the several underwriters, but in no event shall the Common Stock and the Public Warrants comprising
the Units be separately traded until (A) the Company has filed a current report on Form 8-K with the Commission containing an
audited balance sheet reflecting the receipt by the Company of the gross proceeds of the Offering, including the proceeds received
by the Company from the exercise by the underwriters of their right to purchase additional Units in the Offering (the “Over-allotment
Option”), if the Over-allotment Option is exercised prior to the filing of the Form 8-K, and (B) the Company issues a press
release and files with the Commission a current report on Form 8-K announcing when such separate trading shall begin.

 

2.5.
No Fractional Warrants Other Than as Part of Units.  The Company shall not issue fractional Warrants other than
as part of Units, each of which is comprised of one share of Common Stock and one-half of one Public Warrant.  If, upon
the detachment of Public Warrants from Units or otherwise, a holder of Warrants would be entitled to receive a fractional Warrant,
the Company shall round down to the nearest whole number the number of Warrants to be issued to such holder.

 

    	 	3	 

     

    

 

2.6.
Private Placement Warrants; Forward Purchase Warrants.

 

2.6.1.
Private Placement Warrants.  The Private Placement Warrants shall be identical to the Public Warrants, except
that so long as they are held by the Sponsor or any of its Permitted Transferees (as defined below) the Private Placement Warrants:
(i) may be exercised for cash or on a cashless basis, pursuant to subsection 3.3.1(c) hereof, (ii) may not be transferred,
assigned or sold until thirty (30) days after the completion by the Company of an initial Business Combination (as defined below),
and (iii) shall not be redeemable by the Company for cash pursuant to Section 6.1 hereof; provided, however, that in the
case of (ii), the Private Placement Warrants and any shares of Common Stock held by the Sponsor or any of its Permitted Transferees
and issued upon exercise of the Private Placement Warrants may be transferred by the holders thereof:

 

(a)
to the Company’s officers or directors, any affiliates or family members of any of the Company’s officers or directors,
any member(s) of the Sponsor or their affiliates, or any affiliates of the Sponsor;

 

(b)
in the case of an individual, by gift to members of the individual’s immediate family or to a trust, the beneficiary of
which is a member of one 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 such person;

 

(d)
in the case of an individual, pursuant to a qualified domestic relations order;

 

(e)
by virtue of the laws of the state of Delaware or the Sponsor’s operating agreement upon dissolution of the Sponsor;

 

(f)
by private sales or transfers made in connection with the consummation of the Company’s initial Business Combination at
prices no greater than the price at which the Private Placement Warrants were originally purchased;

 

(g)
in the event of the Company’s liquidation prior to the completion of the Company’s initial Business Combination; or

 

(h)
in the event of the Company’s completion of a liquidation, merger, stock exchange or other similar transaction which results
in all of the Company’s stockholders having the right to exchange their shares of Common Stock for cash, securities or other
property subsequent to the completion of the Company’s initial Business Combination;

 

provided,
however, that, in the case of clauses (a) through (h), these transferees (the “Permitted Transferees”) must enter
into a written agreement with the Company agreeing to be bound by the transfer restrictions in this Agreement.

 

    	 	4	 

     

    

 

3.
Terms and Exercise of Warrants.

 

3.1.
Warrant Price.  Each Warrant shall, when countersigned by the Warrant Agent, entitle the Registered Holder thereof,
subject to the provisions of such Warrant and of this Agreement, to purchase from the Company the number of shares of Common Stock
stated therein, at the price of $11.50 per share, subject to the adjustments provided in Section 4 hereof and in the last
sentence of this Section 3.1.  The term “Warrant Price” as used in this Agreement shall mean the price
per share at which shares of Common Stock may be purchased at the time a Warrant is exercised.  The Company in its sole
discretion may lower the Warrant Price at any time prior to the Expiration Date (as defined below) for a period of not less than
twenty (20) Business Days, provided, that the Company shall provide at least twenty (20) days prior written notice of such reduction
to Registered Holders of the Warrants and, provided further that any such reduction shall be identical among all of the Warrants.

 

3.2.
Duration of Warrants.  A Warrant may be exercised only during the period (the “Exercise Period”)
commencing on the later of: (i) the date that is thirty (30) days after the first date on which the Company completes a merger,
capital stock exchange, asset acquisition, stock purchase, reorganization or similar business combination, involving the Company
and one or more businesses (a “Business Combination”) and (ii) the date that is twelve (12) months from the date of
the closing of the Offering, and, in either case, terminating at 5:00 p.m., New York City time on the earlier to occur of: (w)
the date that is five (5) years after the date on which the Company completes its initial Business Combination, (x) the liquidation
of the Company, (y) other than with respect to the Private Placement Warrants held by the Sponsor, the Redemption Date (as defined
below) as provided in Section 6.3 hereof, or (z) the Alternative Redemption Date (as defined below) as provided in Section 6.2
hereof (the “Expiration Date”); provided, however, that the exercise of any Warrant shall be subject to the satisfaction
of any applicable conditions, as set forth in subsection 3.3.2 below with respect to an effective registration statement.  Except
with respect to the right to receive the Redemption Price (as defined below) or the Alternative Redemption Price (as defined below)
(other than with respect to a Private Placement Warrant then held by the Sponsor or its Permitted Transferees) in the event of
a redemption (as set forth in Section 6 hereof), each Warrant (other than a Private Placement Warrant then held by the Sponsor
or its Permitted Transferees in the event of a redemption) not exercised on or before the Expiration Date shall become void, and
all rights thereunder and all rights in respect thereof under this Agreement shall cease at 5:00 p.m.  New York City
time on the Expiration Date.  The Company in its sole discretion may extend the duration of the Warrants by delaying
the Expiration Date; provided, that the Company shall provide at least twenty (20) days prior written notice of any such extension
to Registered Holders of the Warrants and, provided further that any such extension shall be identical in duration among all the
Warrants.

 

3.3.
Exercise of Warrants.

 

3.3.1.
Payment.  Subject to the provisions of the Warrant and this Agreement, a Warrant, when countersigned by the Warrant
Agent, may be exercised by the Registered Holder thereof by surrendering it, at the office of the Warrant Agent, or at the office
of its successor as Warrant Agent, in the Borough of Manhattan, City and State of New York, with the subscription form, as set
forth in the Warrant, duly executed, and by paying in full the Warrant Price for each full share of Common Stock as to which the
Warrant is exercised and any and all applicable taxes due in connection with the exercise of the Warrant, the exchange of the
Warrant for the shares of Common Stock and the issuance of such Common Stock, as follows:

 

    	 	5	 

     

    

 

(a)
in lawful money of the United States, in good certified check or good bank draft payable to the Warrant Agent;

 

(b)
in the event of a redemption pursuant to Section 6 hereof in which the Company’s board of directors (the “Board”)
has elected to require all holders of the Warrants to exercise such Warrants on a “cashless basis,” by surrendering
the Warrants for that number of shares of Common Stock equal to the quotient obtained by dividing (x) the product of the number
of shares of Common Stock underlying the Warrants, multiplied by the difference between the Warrant Price and the “Fair
Market Value”, as defined in this subsection 3.3.1(b) by (y) the Fair Market Value.  Solely for purposes
of this subsection 3.3.1(b) and Section 6.4, the “Fair Market Value” shall mean the average reported last
sale price of the Common Stock for the ten (10) trading days ending on the third trading day prior to the date on which the notice
of redemption is sent to the holders of the Warrants, pursuant to Section 6 hereof;

 

(c)
with respect to any Private Placement Warrant, so long as such Private Placement Warrant is held by the Sponsor or a Permitted
Transferee, by surrendering the Warrants for that number of shares of Common Stock equal to the quotient obtained by dividing
(x) the product of the number of shares of Common Stock underlying the Warrants, multiplied by the difference between the Warrant
Price and the “Fair Market Value”, as defined in this subsection 3.3.1(c), by (y) the Fair Market Value.  Solely
for purposes of this subsection 3.3.1(c), the “Fair Market Value” shall mean the average reported last sale price
of the Common Stock for the ten (10) trading days ending on the third trading day prior to the date on which notice of exercise
of the Warrant is sent to the Warrant Agent; or

 

(d)
as provided in Section 7.4 hereof.

 

3.3.2.
Issuance of Shares of Common Stock on Exercise.  As soon as practicable after the exercise of any Warrant and
the clearance of the funds in payment of the Warrant Price (if payment is pursuant to subsection 3.3.1(a)), the Company shall
issue to the Registered Holder of such Warrant a book-entry position or certificate, as applicable, for the number of full shares
of Common Stock to which he, she or it is entitled, registered in such name or names as may be directed by him, her or it, and
if such Warrant shall not have been exercised in full, a new book-entry position or countersigned Warrant, as applicable, for
the number of shares of Common Stock as to which such Warrant shall not have been exercised.  Notwithstanding the foregoing,
the Company shall not be obligated to deliver any shares of Common Stock pursuant to the exercise of a Warrant and shall have
no obligation to settle such Warrant exercise unless a registration statement under the Securities Act with respect to the shares
of Common Stock underlying the Public Warrants is then effective and a prospectus relating thereto is current, subject to the
Company’s satisfying its obligations under Section 7.4.  No Warrant shall be exercisable and the Company
shall not be obligated to issue shares of Common Stock upon exercise of a Warrant unless the Common Stock issuable upon such Warrant
exercise has been registered, qualified or deemed to be exempt under the securities laws of the state of residence of the Registered
Holder of the Warrants.  In the event that the conditions in the two immediately preceding sentences are not satisfied
with respect to a Warrant, the holder of such Warrant shall not be entitled to exercise such Warrant and such Warrant may have
no value and expire worthless, in which case the purchaser of a Unit containing such Public Warrants shall have paid the full
purchase price for the Unit solely for the shares of Common Stock underlying such Unit.  In no event will the Company
be required to net cash settle the Warrant exercise.  The Company may require holders of Public Warrants to settle the
Warrant on a “cashless basis” pursuant to Section 7.4.  If, by reason of any exercise of warrants on
a “cashless basis”, the holder of any Warrant would be entitled, upon the exercise of such Warrant, to receive a fractional
interest in a share of Common Stock, the Company shall round down to the nearest whole number the number of shares of Common Stock
to be issued to such holder.

 

    	 	6	 

     

    

 

3.3.3.
Valid Issuance.  All shares of Common Stock issued upon the proper exercise of a Warrant in conformity with this
Agreement shall be validly issued, fully paid and non-assessable.

 

3.3.4.
Date of Issuance.  Each person in whose name any book-entry position or certificate, as applicable, for shares
of Common Stock is issued shall for all purposes be deemed to have become the holder of record of such shares of Common Stock
on the date on which the Warrant, or book-entry position representing such Warrant, was surrendered and payment of the Warrant
Price was made, irrespective of the date of delivery of such certificate in the case of a certificated Warrant, except that, if
the date of such surrender and payment is a date when the share transfer books of the Company or book-entry system of the Warrant
Agent are closed, such person shall be deemed to have become the holder of such shares of Common Stock at the close of business
on the next succeeding date on which the share transfer books or book-entry system are open.

 

3.3.5.
Maximum Percentage.  A holder of a Warrant may notify the Company in writing in the event it elects to be subject
to the provisions contained in this subsection 3.3.5; however, no holder of a Warrant shall be subject to this subsection 3.3.5
unless he, she or it makes such election.  If the election is made by a holder, the Warrant Agent shall not effect the
exercise of the holder’s Warrant, and such holder shall not have the right to exercise such Warrant, to the extent that
after giving effect to such exercise, such person (together with such person’s affiliates), to the Warrant Agent’s
actual knowledge, would beneficially own in excess of 9.8% or such other amount as the holder may specify (the “Maximum
Percentage”) of the shares of Common Stock outstanding immediately after giving effect to such exercise.  For
purposes of the foregoing sentence, the aggregate number of shares of Common Stock beneficially owned by such person and its affiliates
shall include the number of shares of Common Stock issuable upon exercise of the Warrant with respect to which the determination
of such sentence is being made, but shall exclude shares of Common Stock that would be issuable upon (x) exercise of the remaining,
unexercised portion of the Warrant beneficially owned by such person and its affiliates and (y) exercise or conversion of the
unexercised or unconverted portion of any other securities of the Company beneficially owned by such person and its affiliates
(including, without limitation, any convertible notes or convertible preferred stock or warrants) subject to a limitation on conversion
or exercise analogous to the limitation contained herein.  Except as set forth in the preceding sentence, for purposes
of this paragraph, beneficial ownership shall be calculated in accordance with Section 13(d) of the Securities Exchange Act
of 1934, as amended (the “Exchange Act”).  For purposes of the Warrant, in determining the number of outstanding
shares of Common Stock, the holder may rely on the number of outstanding shares of Common Stock as reflected in (1) the Company’s
most recent annual report on Form 10-K, quarterly report on Form 10-Q, current report on Form 8-K or other public filing with
the Commission as the case may be, (2) a more recent public announcement by the Company or (3) any other notice by the Company
or the Transfer Agent setting forth the number of shares of Common Stock outstanding.  For any reason at any time, upon
the written request of the holder of the Warrant, the Company shall, within two (2) Business Days, confirm orally and in writing
to such holder the number of shares of Common Stock then outstanding.  In any case, the number of outstanding shares
of Common Stock shall be determined after giving effect to the conversion or exercise of equity securities of the Company by the
holder and its affiliates since the date as of which such number of outstanding shares of Common Stock was reported.  By
written notice to the Company, the holder of a Warrant may from time to time increase or decrease the Maximum Percentage applicable
to such holder to any other percentage specified in such notice; provided, however, that any such increase shall not be effective
until the sixty-first (61st) day after such notice is delivered to the Company.

4.
Adjustments.

 

4.1.
Stock Dividends.

 

4.1.1.
Split-Ups.  If after the date hereof, and subject to the provisions of Section 4.6 below, the number of
outstanding shares of Common Stock is increased by a stock dividend payable in shares of Common Stock, or by a split-up of shares
of Common Stock or other similar event, then, on the effective date of such stock dividend, split-up or similar event, the number
of shares of Common Stock issuable on exercise of each Warrant shall be increased in proportion to such increase in the outstanding
shares of Common Stock. A rights offering to holders of the Common Stock entitling holders to purchase shares of Common Stock
at a price less than the “Fair Market Value” (as defined below) shall be deemed a stock dividend of a number of shares
of Common Stock equal to the product of (i) the number of shares of Common Stock actually sold in such rights offering (or issuable
under any other equity securities sold in such rights offering that are convertible into or exercisable for the Common Stock)
multiplied by (ii) one (1) minus the quotient of (x) the price per share of Common Stock paid in such rights offering divided
by (y) the Fair Market Value.  For purposes of this subsection 4.1.1, (i) if the rights offering is for securities
convertible into or exercisable for Common Stock, in determining the price payable for Common Stock, there shall be taken into
account any consideration received for such rights, as well as any additional amount payable upon exercise or conversion and (ii)
“Fair Market Value” means the volume weighted average price of the Common Stock as reported during the ten (10) trading
day period ending on the trading day prior to the first date on which the shares of Common Stock trade on the applicable exchange
or in the applicable market, regular way, without the right to receive such rights.

 

4.1.2.
Extraordinary Dividends.  If the Company, at any time while the Warrants are outstanding and unexpired, shall
pay a dividend or make a distribution in cash, securities or other assets to the holders of the Common Stock on account of such
shares of Common Stock (or other shares of the Company’s capital stock into which the Warrants are convertible), other than
(a) as described in subsection 4.1.1 above, (b) Ordinary Cash Dividends (as defined below), (c) to satisfy the redemption
rights of the holders of the Common Stock in connection with a proposed initial Business Combination, (d) to satisfy the redemption
rights of the holders of Common Stock in connection with a stockholder vote to approve 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 Common Stock if the Company does not complete the Company’s initial Business Combination within the time period
set forth in the Company’s amended and restated certificate of incorporation, or (e) in connection with the redemption of
the Common Stock upon the Company’s failure to complete the Company’s initial Business Combination (any such non-excluded
event being referred to herein as an “Extraordinary Dividend”), then the Warrant Price shall be decreased, effective
immediately after the effective date of such Extraordinary Dividend, by the amount of cash and/or the fair market value (as determined
by the Board, in good faith) of any securities or other assets paid on each share of Common Stock in respect of such Extraordinary
Dividend.  For purposes of this subsection 4.1.2, “Ordinary Cash Dividends” means any cash dividend
or cash distribution which, when combined on a per share basis, with the per share amounts of all other cash dividends and cash
distributions paid on the Common Stock during the 365-day period ending on the date of declaration of such dividend or distribution
(as adjusted to appropriately reflect any of the events referred to in other subsections of this Section 4 and excluding
cash dividends or cash distributions that resulted in an adjustment to the Warrant Price or to the number of shares of Common
Stock issuable on exercise of each Warrant) does not exceed $0.10 (being 1% of the offering price of the Units in the Offering).

4.2.
Aggregation of Shares.  If after the date hereof, and subject to the provisions of Section 4.6 hereof, the
number of outstanding shares of Common Stock is decreased by a consolidation, combination, reverse stock split or reclassification
of shares of Common Stock or other similar event, then, on the effective date of such consolidation, combination, reverse stock
split, reclassification or similar event, the number of shares of Common Stock issuable on exercise of each Warrant shall be decreased
in proportion to such decrease in outstanding shares of Common Stock.

 

4.3.
Adjustments in Exercise Price.  Whenever the number of shares of Common Stock purchasable upon the exercise of
the Warrants is adjusted, as provided in subsection 4.1.1 or Section 4.2 above, the Warrant Price shall be adjusted
(to the nearest cent) by multiplying such Warrant Price immediately prior to such adjustment by a fraction (a) the numerator of
which shall be the number of shares of Common Stock purchasable upon the exercise of the Warrants immediately prior to such adjustment,
and (b) the denominator of which shall be the number of shares of Common Stock so purchasable immediately thereafter.  If,
(x) in connection with the closing of the initial Business Combination, the Company issues additional shares of Common Stock or
securities of the Company which are convertible into, or exchangeable or exercisable for, equity securities of the Company, including
any securities issued by the Company which are pledged to secure any obligation of any holder to purchase equity securities of
the Company, at an issue price or effective issue price of less than $9.20 per share of Common Stock, with such issue price or
effective issue price to be determined in good faith by the Board (and in the case of any such issuance to the Sponsor or its
affiliates, without taking into account any shares of common stock of the Company issued prior to the Offering and held by the
Sponsor or such affiliates, as applicable, prior to such issuance) (the “Newly Issued Price”) and (y) the volume-weighted
average trading price of shares of Common Stock during the twenty (20) trading day period starting on the trading day prior to
the day on which the Company consummates its initial Business Combination (such price, the “Market Value”) is below
$9.20 per share, the Warrant Price shall be adjusted (to the nearest cent) to be equal to 115% of the higher of the Market Value
and the Newly Issued Price, and the $10.00 and $18.00 per share redemption trigger prices described in Section 6.2 and Section
6.1, respectively, will be adjusted (to the nearest cent) to be equal to 100% and 180%, respectively, of the higher of the Market
Value and the Newly Issued Price.

 

    	 	9	 

     

    

 

4.4.
Replacement of Securities upon Reorganization, etc. In case of any reclassification or reorganization of the outstanding
shares of Common Stock (other than a change under subsections 4.1.1 or 4.1.2 or Section 4.2 hereof or that solely affects
the par value of such shares of Common Stock), or in the case of any merger or consolidation of the Company with or into another
corporation (other than a consolidation or merger in which the Company is the continuing corporation and that does not result
in any reclassification or reorganization of the outstanding shares of Common Stock), or in the case of any sale or conveyance
to another corporation or entity of the assets or other property of the Company as an entirety or substantially as an entirety
in connection with which the Company is dissolved, the holders of the Warrants shall thereafter have the right to purchase and
receive, upon the basis and upon the terms and conditions specified in the Warrants and in lieu of the shares of Common Stock
of the Company immediately theretofore purchasable and receivable upon the exercise of the rights represented thereby, the kind
and amount of shares of stock or other securities or property (including cash) receivable upon such reclassification, reorganization,
merger or consolidation, or upon a dissolution following any such sale or transfer, that the holder of the Warrants would have
received if such holder had exercised his, her or its Warrant(s) immediately prior to such event (the “Alternative Issuance”);
provided, however, that (i) if the holders of the Common Stock were entitled to exercise a right of election as to the kind or
amount of securities, cash or other assets receivable upon such consolidation or merger, then the kind and amount of securities,
cash or other assets constituting the Alternative Issuance for which each Warrant shall become exercisable shall be deemed to
be the weighted average of the kind and amount received per share by the holders of the Common Stock in such consolidation or
merger that affirmatively make such election, and (ii) if a tender, exchange or redemption offer shall have been made to and accepted
by the holders of the Common Stock (other than a tender, exchange or redemption offer made by the Company in connection with redemption
rights held by stockholders of the Company as provided for in the Company’s amended and restated certificate of incorporation
or as a result of the repurchase of shares of Common Stock by the Company if a proposed initial Business Combination is presented
to the stockholders of the Company for approval) under circumstances in which, upon completion of such tender or exchange offer,
the maker thereof, together with members of any group (within the meaning of Rule 13d-5(b)(1) under the Exchange Act (or any successor
rule)) of which such maker is a part, and together with any affiliate or associate of such maker (within the meaning of Rule 12b-2
under the Exchange Act (or any successor rule)) and any members of any such group of which any such affiliate or associate is
a part, own beneficially (within the meaning of Rule 13d-3 under the Exchange Act (or any successor rule)) more than 50% of the
outstanding shares of Common Stock, the holder of a Warrant shall be entitled to receive as the Alternative Issuance, the highest
amount of cash, securities or other property to which such holder would actually have been entitled as a stockholder if such Warrant
holder had exercised the Warrant prior to the expiration of such tender or exchange offer, accepted such offer and all of the
Common Stock held by such holder had been purchased pursuant to such tender or exchange offer, subject to adjustments (from and
after the consummation of such tender or exchange offer) as nearly equivalent as possible to the adjustments provided for in this
Section 4; provided, further, that if less than 70% of the consideration receivable by the holders of the Common Stock in
the applicable event is payable in the form of common stock in the successor entity that is listed for trading on a national securities
exchange or is quoted in an established over-the-counter market, or is to be so listed for trading or quoted immediately following
such event, and if the Registered Holder properly exercises the Warrant within thirty (30) days following the public disclosure
of the consummation of such applicable event by the Company pursuant to a Current Report on Form 8-K filed with the Commission,
the Warrant Price shall be reduced by an amount (in dollars) equal to the difference of (i) the Warrant Price in effect prior
to such reduction minus (ii) (A) the Per Share Consideration (as defined below) (but in no event less than zero) minus (B) the
Black-Scholes Warrant Value (as defined below).  The “Black-Scholes Warrant Value” means the value of a
Warrant immediately prior to the consummation of the applicable event based on the Black-Scholes Warrant Model for a Capped American
Call on Bloomberg Financial Markets (“Bloomberg”).  For purposes of calculating such amount, (1) Section 6
of this Agreement shall be taken into account, (2) the price of each share of Common Stock shall be the volume weighted average
price of the Common Stock as reported during the ten (10) trading day period ending on the trading day prior to the effective
date of the applicable event, (3) the assumed volatility shall be the 90 day volatility obtained from the HVT function on Bloomberg
determined as of the trading day immediately prior to the day of the announcement of the applicable event, and (4) the assumed
risk-free interest rate shall correspond to the U.S. Treasury rate for a period equal to the remaining term of the Warrant. “Per
Share Consideration” means (i) if the consideration paid to holders of the Common Stock consists exclusively of cash, the
amount of such cash per share of Common Stock, and (ii) in all other cases, the volume weighted average price of the Common Stock
as reported during the ten (10) trading day period ending on the trading day prior to the effective date of the applicable event.  If
any reclassification or reorganization also results in a change in shares of Common Stock covered by subsection 4.1.1, then
such adjustment shall be made pursuant to subsection 4.1.1 or Sections 4.2, 4.3 and this Section 4.4.  The
provisions of this Section 4.4 shall similarly apply to successive reclassifications, reorganizations, mergers or consolidations,
sales or other transfers.  In no event will the Warrant Price be reduced to less than the par value per share issuable
upon exercise of the Warrant.

 

    	 	10	 

     

    

 

4.5.
Notices of Changes in Warrant.  Upon every adjustment of the Warrant Price or the number of shares of Common
Stock issuable upon exercise of a Warrant, the Company shall give written notice thereof to the Warrant Agent, which notice shall
state the Warrant Price resulting from such adjustment and the increase or decrease, if any, in the number of shares of Common
Stock purchasable at such price upon the exercise of a Warrant, setting forth in reasonable detail the method of calculation and
the facts upon which such calculation is based.  Upon the occurrence of any event specified in Sections 4.1, 4.2,
4.3 or 4.4, the Company shall give written notice of the occurrence of such event to each holder of a Warrant, at the last address
set forth for such holder in the Warrant Register, of the record date or the effective date of the event.  Failure to
give such notice, or any defect therein, shall not affect the legality or validity of such event.

 

4.6.
No Fractional Shares.  Notwithstanding any provision contained in this Agreement to the contrary, the Company
shall not issue fractional shares of Common Stock upon the exercise of Warrants.  If, by reason of any adjustment made
pursuant to this Section 4, the holder of any Warrant would be entitled, upon the exercise of such Warrant, to receive a
fractional interest in a share, the Company shall, upon such exercise, round down to the nearest whole number the number of shares
of Common Stock to be issued to such holder.

 

    	 	11	 

     

    

 

4.7.
Form of Warrant.  The form of Warrant need not be changed because of any adjustment pursuant to this Section 4,
and Warrants issued after such adjustment may state the same Warrant Price and the same number of shares of Common Stock as is
stated in the Warrants initially issued pursuant to this Agreement; provided, however, that the Company may at any time in its
sole discretion make any change in the form of Warrant that the Company may deem appropriate and that does not affect the substance
thereof, and any Warrant thereafter issued or countersigned, whether in exchange or substitution for an outstanding Warrant or
otherwise, may be in the form as so changed.

 

4.8.
Other Events.  In case any event shall occur affecting the Company as to which none of the provisions of the
preceding subsections of this Section 4 are strictly applicable, but which would require an adjustment to the terms
of the Warrants in order to (i) avoid an adverse impact on the Warrants and (ii) effectuate the intent and purpose of this Section 4,
then, in each such case, the Company shall appoint a firm of independent public accountants or investment banking or other appraisal
firm of recognized national standing, which shall give its opinion as to whether or not any adjustment to the rights represented
by the Warrants is necessary to effectuate the intent and purpose of this Section 4 and, if they determine that an adjustment
is necessary, the terms of such adjustment.  The Company shall adjust the terms of the Warrants in a manner that is
consistent with any adjustment recommended in such opinion.

 

5.
Transfer and Exchange of Warrants.

 

5.1.
Registration of Transfer.  The Warrant Agent shall register the transfer, from time to time, of any outstanding
Warrant upon the Warrant Register, upon surrender of such Warrant for transfer, properly endorsed with signatures properly guaranteed
and accompanied by appropriate instructions for transfer.  Upon any such transfer, a new Warrant representing an equal
aggregate number of Warrants shall be issued and the old Warrant shall be cancelled by the Warrant Agent.  The Warrants
so cancelled shall be delivered by the Warrant Agent to the Company from time to time upon request.

 

5.2.
Procedure for Surrender of Warrants.  Warrants may be surrendered to the Warrant Agent, together with a written
request for exchange or transfer, and thereupon the Warrant Agent shall issue in exchange therefor one or more new Warrants as
requested by the Registered Holder of the Warrants so surrendered, representing an equal aggregate number of Warrants; provided,
however, that in the event that a Warrant surrendered for transfer bears a restrictive legend (as in the case of the Private Placement
Warrants), the Warrant Agent shall not cancel such Warrant and issue new Warrants in exchange thereof until the Warrant Agent
has received an opinion of counsel for the Company stating that such transfer may be made and indicating whether the new Warrants
must also bear a restrictive legend.

 

5.3.
Transfers of Fractions of Warrants.  The Warrant Agent shall not be required to effect any registration of transfer
or exchange of Warrants which would require the issuance of a warrant certificate or book-entry position for a fraction of a warrant,
except as part of the Units.

 

    	 	12	 

     

    

 

5.4.
Service Charges.  No service charge shall be made for any exchange or registration of transfer of Warrants.

 

5.5.
Warrant Execution and Countersignature.  The Warrant Agent is hereby authorized to countersign and to deliver,
in accordance with the terms of this Agreement, the Warrants required to be issued pursuant to the provisions of this Section 5,
and the Company, whenever required by the Warrant Agent, shall supply the Warrant Agent with Warrants duly executed on behalf
of the Company for such purpose.

 

5.6.
Transfer of Warrants.  Prior to the Detachment Date, the Public Warrants may be transferred or exchanged only
together with the Unit in which such Warrant is included, and only for the purpose of effecting, or in conjunction with, a transfer
or exchange of such Unit.  Furthermore, each transfer of a Unit on the register relating to such Units shall operate
also to transfer the Warrants included in such Unit.  Notwithstanding the foregoing, the provisions of this Section 5.6
shall have no effect on any transfer of Warrants on and after the Detachment Date.

 

6.
Redemption.

 

6.1.
Redemption of Warrants for Cash.  Subject to Section 6.5 hereof, not less than all of the outstanding Warrants
may be redeemed, at the option of the Company, at any time while they are exercisable and prior to their expiration, at the office
of the Warrant Agent, upon notice to the Registered Holders of the Warrants, as described in Section 6.3 below, at the price
of $0.01 per Warrant (the “Redemption Price”), provided that the last sales price of the Common Stock reported has
been at least $18.00 per share (subject to adjustment in compliance with Section 4 hereof), on each of twenty (20) trading
days within the thirty (30) trading-day period ending on the third trading day prior to the date on which notice of the redemption
is given and provided that there is an effective registration statement covering the shares of Common Stock issuable upon exercise
of the Warrants, and a current prospectus relating thereto, available throughout the 30-day Redemption Period (as defined in Section 6.3
below) or the Company has elected to require the exercise of the Warrants on a “cashless basis” pursuant to subsection 3.3.1.

 

6.2.
Redemption of Warrants for Common Stock.  Subject to Section 6.5 hereof, not less than all of the outstanding
Warrants may be redeemed, at the option of the Company, commencing ninety (90) days after they are first exercisable and prior
to their expiration, at the office of the Warrant Agent, upon notice to the Registered Holders of the Warrants, as described in Section 6.3 below,
at a price equal to a number of shares of Common Stock determined by reference to the table below, based on the redemption date
(calculated for purposes of the table as the period to expiration of the Warrants) and the “Fair Market Value” (as
such term is defined in subsection 3.3.1(b) (the “Alternative Redemption Price”), provided that the
last sales price of the Common Stock reported has been at least $10.00 per share (subject to adjustment in compliance with Section 4
hereof), on the trading day prior to the date on which notice of the redemption is given and provided that there is
an effective registration statement covering the shares of Common Stock issuable upon exercise of the Warrants, and a current
prospectus relating thereto, available throughout the 30-day Redemption Period (as defined in Section 6.3 below)
or the Company has elected to require the exercise of warrants on a “cashless basis” pursuant to subsection 3.3.1.

If
the exact Fair Market Value and Redemption Date (as defined below) are between two values in the table above or the Redemption
Date is between two redemption dates in the table above, the number of shares of Common Stock to be issued for each Warrant redeemed
will be determined by a straight-line interpolation between the number of shares set forth for the higher and lower Fair Market
Values and the earlier and later redemption dates, as applicable, based on a 365-day year.

 

The
stock prices set forth in the column headings of the table above shall be adjusted as of any date on which the number of shares
issuable upon exercise of a Warrant is adjusted pursuant to Section 4.  The adjusted stock prices in the column
headings shall equal the stock prices immediately prior to such adjustment, multiplied by a fraction, the numerator of which is
the number of shares deliverable upon exercise of a Warrant immediately prior to such adjustment and the denominator of which
is the number of shares deliverable upon exercise of a Warrant as so adjusted.  The number of shares in the table above
shall be adjusted in the same manner and at the same time as the number of shares issuable upon exercise of a Warrant.

 

    	 	14	 

     

    

 

6.3.
Date Fixed for, and Notice of, Redemption.  In the event that the Company elects to redeem all of the Warrants
pursuant to Section 6.1, the Company shall fix a date for the redemption (the “Redemption Date”).  In
the event that the Company elects to redeem all of the Warrants pursuant to Section 6.2, the Company shall fix a date for
redemption (the “Alternative Redemption Date”).  Notice of redemption shall be mailed by first class mail,
postage prepaid, by the Company not less than thirty (30) days prior to the Redemption Date (the “30-day Redemption Period”)
to the Registered Holders of the Warrants to be redeemed at their last addresses as they shall appear on the registration books.  Any
notice mailed in the manner herein provided shall be conclusively presumed to have been duly given whether or not the Registered
Holder received such notice.

 

6.4.
Exercise After Notice of Redemption.  The Warrants may be exercised, for cash (or on a “cashless basis”
in accordance with subsection 3.3.1(b) of this Agreement) at any time after notice of redemption shall have been given by
the Company pursuant to Section 6.3 hereof and prior to the Redemption Date.  In the event that the Company determines
to require all holders of Warrants to exercise their Warrants on a “cashless basis” pursuant to subsection 3.3.1,
the notice of redemption shall contain the information necessary to calculate the number of shares of Common Stock to be received
upon exercise of the Warrants, including the “Fair Market Value” (as such term is defined in subsection 3.3.1(b)
hereof) in such case.  On and after the Redemption Date, the record holder of the Warrants shall have no further rights
except to receive, upon surrender of the Warrants, the Redemption Price or the Alternative Redemption Price, as applicable.

 

6.5.
Effect of Private Placement Warrants and Forward Purchase Warrants.

 

6.5.1.
The Company agrees that the redemption rights provided in Section 6.1 shall not apply to the Private Placement Warrants if
at the time of the redemption such Private Placement Warrants continue to be held by the Sponsor or its Permitted Transferees.  However,
once such Private Placement Warrants are transferred (other than to Permitted Transferees under Section 2.6), the Company
may redeem the Private Placement Warrants, provided that the criteria for redemption are met, including the opportunity of the
holder of such Private Placement Warrants to exercise the Private Placement Warrants prior to redemption pursuant to Section 6.4.  Private
Placement Warrants that are transferred to persons other than Permitted Transferees shall upon such transfer cease to be Private
Placement Warrants and shall become Public Warrants under this Agreement.

 

6.5.2.
The Company agrees that the provisions of Section 6.2 shall apply to the Private Placement Warrants pari passu with the Public
Warrants.

 

7.
Other Provisions Relating to Rights of Holders of Warrants.

 

7.1.
No Rights as Stockholder.  A Warrant does not entitle the Registered Holder thereof to any of the rights of a
stockholder of the Company, including, without limitation, the right to receive dividends, or other distributions, exercise any
preemptive rights to vote or to consent or to receive notice as stockholders in respect of the meetings of stockholders or the
election of directors of the Company or any other matter.

 

    	 	15	 

     

    

 

7.2.
Lost, Stolen, Mutilated, or Destroyed Warrants.  If any Warrant is lost, stolen, mutilated, or destroyed, the
Company and the Warrant Agent may on such terms as to indemnity or otherwise as they may in their discretion impose (which shall,
in the case of a mutilated Warrant, include the surrender thereof), issue a new Warrant of like denomination, tenor, and date
as the Warrant so lost, stolen, mutilated, or destroyed.  Any such new Warrant shall constitute a substitute contractual
obligation of the Company, whether or not the allegedly lost, stolen, mutilated, or destroyed Warrant shall be at any time enforceable
by anyone.

 

7.3.
Reservation of Common Stock.  The Company shall at all times reserve and keep available a number of its authorized
but unissued shares of Common Stock that shall be sufficient to permit the exercise in full of all outstanding Warrants issued
pursuant to this Agreement.

 

7.4.
Registration of Common Stock; Cashless Exercise at Company’s Option.

 

7.4.1.
Registration of the Common Stock.  The Company agrees that as soon as practicable, but in no event later than
fifteen (15) Business Days after the closing of its initial Business Combination, it shall use its best efforts to file with the
Commission a registration statement for the registration, under the Securities Act, of the shares of Common Stock issuable upon
exercise of the Warrants.  The Company shall use its best efforts to cause the same to become effective and to maintain
the effectiveness of such registration statement, and a current prospectus relating thereto, until the expiration of the Warrants
in accordance with the provisions of this Agreement.  If any such registration statement has not been declared effective
by the 60th Business Day following the closing of the Business Combination, holders of the Warrants shall have the right, during
the period beginning on the 61st Business Day after the closing of the Business Combination and ending upon such registration
statement being declared effective by the Commission, and during any other period when the Company shall fail to have maintained
an effective registration statement covering the shares of Common Stock issuable upon exercise of the Warrants, to exercise such
Warrants on a “cashless basis,” by exchanging the Warrants (in accordance with Section 3(a)(9) of the Securities
Act (or any successor statute) or another exemption) for that number of shares of Common Stock equal to the quotient obtained
by dividing (x) the product of the number of shares of Common Stock underlying the Warrants, multiplied by the difference between
the Warrant Price and the “Fair Market Value” (as defined below) by (y) the Fair Market Value.  Solely for
purposes of this subsection 7.4.1, “Fair Market Value” shall mean the volume weighted average price of the Common
Stock as reported during the ten (10) trading day period ending on the trading day prior to the date that notice of exercise is
received by the Warrant Agent from the holder of such Warrants or its securities broker or intermediary.  The date that
notice of cashless exercise is received by the Warrant Agent shall be conclusively determined by the Warrant Agent. In connection
with the “cashless exercise” of a Public Warrant, the Company shall, upon request, provide the Warrant Agent with
an opinion of counsel for the Company (which shall be an outside law firm with securities law experience) stating that (i) the
exercise of the Warrants on a cashless basis in accordance with this subsection 7.4.1 is not required to be registered under
the Securities Act and (ii) the shares of Common Stock issued upon such exercise shall be freely tradable under United States
federal securities laws by anyone who is not an affiliate (as such term is defined in Rule 144 under the Securities Act (or any
successor rule)) of the Company and, accordingly, shall not be required to bear a restrictive legend.  Except as provided
in subsection 7.4.2, for the avoidance of any doubt, unless and until all of the Warrants have been exercised, the Company
shall continue to be obligated to comply with its registration obligations under the first three sentences of this subsection 7.4.1.

 

    	 	16	 

     

    

 

7.4.2.
Cashless Exercise at Company’s Option.  If the Common Stock is at the time of any exercise of a Warrant
not listed on a national securities exchange such that it satisfies the definition of a “covered security” under Section 18(b)(1)
of the Securities Act (or any successor statute), the Company may, at its option, (i) require holders of Public Warrants who exercise
Public Warrants to exercise such Public Warrants on a “cashless basis” in accordance with Section 3(a)(9) of
the Securities Act (or any successor statute) as described in subsection 7.4.1 and (ii) in the event the Company so elects,
the Company shall (x) not be required to file or maintain in effect a registration statement for the registration, under the Securities
Act, of the Common Stock issuable upon exercise of the Warrants, notwithstanding anything in this Agreement to the contrary and
(y) use its best efforts to register or qualify the Common Stock issuable upon exercise of the Public Warrant under the blue sky
laws of the state of residence of the exercising Public Warrant holder to the extent an exemption is not available.

 

8.
Concerning the Warrant Agent and Other Matters.

 

8.1.
Payment of Taxes.  The Company shall from time to time promptly pay all taxes and charges that may be imposed
upon the Company or the Warrant Agent in respect of the issuance or delivery of shares of Common Stock upon the exercise of the
Warrants, but the Company shall not be obligated to pay any transfer taxes in respect of the Warrants or such shares of Common
Stock.

 

8.2.
Resignation, Consolidation, or Merger of Warrant Agent.

 

8.2.1.
Appointment of Successor Warrant Agent.  The Warrant Agent, or any successor to it hereafter appointed, may resign its
duties and be discharged from all further duties and liabilities hereunder after giving sixty (60) days’ notice in writing
to the Company.  If the office of the Warrant Agent becomes vacant by resignation or incapacity to act or otherwise,
the Company shall appoint in writing a successor Warrant Agent in place of the Warrant Agent.  If the Company shall
fail to make such appointment within a period of thirty (30) days after it has been notified in writing of such resignation or
incapacity by the Warrant Agent or by the holder of a Warrant (who shall, with such notice, submit his, her or its Warrant for
inspection by the Company), then the holder of any Warrant may apply to the Supreme Court of the State of New York for the County
of New York for the appointment of a successor Warrant Agent at the Company’s cost.  Any successor Warrant Agent,
whether appointed by the Company or by such court, shall be a corporation organized and existing under the laws of the State of
New York, in good standing and having its principal office in the Borough of Manhattan, City and State of New York, and authorized
under such laws to exercise corporate trust powers and subject to supervision or examination by federal or state authority.  After
appointment, any successor Warrant Agent shall be vested with all the authority, powers, rights, immunities, duties, and obligations
of its predecessor Warrant Agent with like effect as if originally named as Warrant Agent hereunder, without any further act or
deed; but if for any reason it becomes necessary or appropriate, the predecessor Warrant Agent shall execute and deliver, at the
expense of the Company, an instrument transferring to such successor Warrant Agent all the authority, powers, and rights of such
predecessor Warrant Agent hereunder; and upon request of any successor Warrant Agent the Company shall make, execute, acknowledge,
and deliver any and all instruments in writing for more fully and effectually vesting in and confirming to such successor Warrant
Agent all such authority, powers, rights, immunities, duties, and obligations.

 

    	 	17	 

     

    

 

8.2.2.
Notice of Successor Warrant Agent.  In the event a successor Warrant Agent shall be appointed, the Company shall give
notice thereof to the predecessor Warrant Agent and the Transfer Agent for the Common Stock not later than the effective date
of any such appointment.

 

8.2.3.
Merger or Consolidation of Warrant Agent.  Any corporation into which the Warrant Agent may be merged or with which
it may be consolidated or any corporation resulting from any merger or consolidation to which the Warrant Agent shall be a party
shall be the successor Warrant Agent under this Agreement without any further act.

 

8.3.
Fees and Expenses of Warrant Agent.

 

8.3.1.
Remuneration.  The Company agrees to pay the Warrant Agent reasonable remuneration for its services as such Warrant
Agent hereunder and shall, pursuant to its obligations under this Agreement, reimburse the Warrant Agent upon demand for all expenditures
that the Warrant Agent may reasonably incur in the execution of its duties hereunder.

 

8.3.2.
Further Assurances.  The Company agrees to perform, execute, acknowledge, and deliver or cause to be performed,
executed, acknowledged, and delivered all such further and other acts, instruments, and assurances as may reasonably be required
by the Warrant Agent for the carrying out or performing of the provisions of this Agreement.

 

8.4.
Liability of Warrant Agent.

 

8.4.1.
Reliance on Company Statement.  Whenever in the performance of its duties under this Agreement, the Warrant Agent
shall deem it necessary or desirable that any fact or matter be proved or established by the Company prior to taking or suffering
any action hereunder, such fact or matter (unless other evidence in respect thereof be herein specifically prescribed) may be
deemed to be conclusively proved and established by a statement signed by the Chief Executive Officer, Chief Financial Officer,
Secretary or Chairman of the Board of the Company and delivered to the Warrant Agent.  The Warrant Agent may rely upon
such statement for any action taken or suffered in good faith by it pursuant to the provisions of this Agreement.

 

8.4.2.
Indemnity.  The Warrant Agent shall be liable hereunder only for its own gross negligence, willful misconduct
or bad faith.  The Company agrees to indemnify the Warrant Agent and save it harmless against any and all liabilities,
including judgments, costs and reasonable counsel fees, for anything done or omitted by the Warrant Agent in the execution of
this Agreement, except as a result of the Warrant Agent’s gross negligence, willful misconduct or bad faith.

 

    	 	18	 

     

    

 

8.4.3.
Exclusions.  The Warrant Agent shall have no responsibility with respect to the validity of this Agreement or
with respect to the validity or execution of any Warrant (except its countersignature thereof).  The Warrant Agent shall
not be responsible for any breach by the Company of any covenant or condition contained in this Agreement or in any Warrant.  The
Warrant Agent shall not be responsible to make any adjustments required under the provisions of Section 4 hereof or responsible
for the manner, method, or amount of any such adjustment or the ascertaining of the existence of facts that would require any
such adjustment; nor shall it by any act hereunder be deemed to make any representation or warranty as to the authorization or
reservation of any shares of Common Stock to be issued pursuant to this Agreement or any Warrant or as to whether any shares of
Common Stock shall, when issued, be valid and fully paid and non-assessable.

 

8.5.
Acceptance of Agency.  The Warrant Agent hereby accepts the agency established by this Agreement and agrees to
perform the same upon the terms and conditions herein set forth and among other things, shall account promptly to the Company
with respect to Warrants exercised and concurrently account for, and pay to the Company, all monies received by the Warrant Agent
for the purchase of shares of Common Stock through the exercise of the Warrants.

 

8.6.
Waiver.  The Warrant Agent has no right of set-off or any other right, title, interest or claim of any kind (“Claim”)
in, or to any distribution of, the Trust Account (as defined in that certain Investment Management Trust Agreement, dated as of
the date hereof, by and between the Company and the Warrant Agent as trustee thereunder) and hereby agrees not to seek recourse,
reimbursement, payment or satisfaction for any Claim against the Trust Account for any reason whatsoever.  The Warrant
Agent hereby waives any and all Claims against the Trust Account and any and all rights to seek access to the Trust Account.

 

9.
Miscellaneous Provisions.

Agent shall bind and inure to the benefit of their respective successors and assigns.

proceeding or claim against it arising out of or relating in any way to this Agreement shall be brought and enforced in the courts

Warrant
Certificate

 

This
Warrant Certificate certifies that, or registered assigns, is the registered holder of warrant(s) evidenced hereby (the
“Warrants” and each, a “Warrant”) to purchase shares of Class A common stock,
$0.0001 par value per share (“Common Stock”), of Yellowstone Acquisition Company, a Delaware corporation
(the “Company”).  Each Warrant entitles the holder, upon exercise during the period set forth
in the Warrant Agreement referred to below, to receive from the Company that number of fully paid and non-assessable shares of
Common Stock as set forth below, at the exercise price (the “Exercise Price”) as determined pursuant
to the Warrant Agreement, payable by certified or official bank check payable to the Company (or through “cashless
exercise” as provided for in the Warrant Agreement) upon surrender of this Warrant Certificate and payment of the
Exercise Price at the office or agency of the Warrant Agent referred to below, subject to the conditions set forth herein and
in the Warrant Agreement.  Defined terms used in this Warrant Certificate but not defined herein shall have the meanings
given to them in the Warrant Agreement.

 

Each
Warrant is initially exercisable for one fully paid and non-assessable share of Common Stock.   No fractional shares
will be issued upon exercise of any Warrant. If, upon exercise of the Warrants, a holder would be entitled to receive a fractional
interest in a share Common Stock, the Company will, upon exercise, round down to the nearest whole number the number of shares
of Common Stock to be issued to the warrant holder. The number of shares of Common Stock issuable upon exercise of the Warrants
is subject to adjustment upon the occurrence of certain events as set forth in the Warrant Agreement.

 

The
initial Exercise Price is equal to $11.50 per share of Common Stock.  The Exercise Price is subject to adjustment upon
the occurrence of certain events as set forth in the Warrant Agreement.

 

Subject
to the conditions set forth in the Warrant Agreement, the Warrants may be exercised only during the Exercise Period and to the
extent not exercised by the end of such Exercise Period, such Warrants shall become void.

Reference

shall for all purposes have the same effect as though fully set forth at this place.

The
Warrants evidenced by this Warrant Certificate are part of a duly authorized issue of Warrants entitling the holder on exercise
to receive shares of Common Stock and are issued or to be issued pursuant to a Warrant Agreement, dated as of [●], 2020
(the “Warrant Agreement”), duly executed and delivered by the Company to Continental Stock Transfer
& Trust Company, a New York corporation, as warrant agent (the “Warrant Agent”), which Warrant Agreement
is hereby incorporated by reference in and made a part of this instrument and is hereby referred to for a description of the rights,
limitation of rights, obligations, duties and immunities thereunder of the Warrant Agent, the Company and the holders (the words
“holders” or “holder” meaning the Registered Holders or Registered Holder,
respectively) of the Warrants. A copy of the Warrant Agreement may be obtained by the holder hereof upon written request to the
Company.  Defined terms used in this Warrant Certificate but not defined herein shall have the meanings given to them
in the Warrant Agreement.

 

Warrants
may be exercised at any time during the Exercise Period set forth in the Warrant Agreement.  The holder of Warrants
evidenced by this Warrant Certificate may exercise them by surrendering this Warrant Certificate, with the form of election to
purchase set forth hereon properly completed and executed, together with payment of the Exercise Price as specified in the Warrant
Agreement (or through “cashless exercise” as provided for in the Warrant Agreement) at the principal
corporate trust office of the Warrant Agent.  In the event that upon any exercise of Warrants evidenced hereby the number
of Warrants exercised shall be less than the total number of Warrants evidenced hereby, there shall be issued to the holder hereof
or his, her or its assignee, a new Warrant Certificate evidencing the number of Warrants not exercised.

 

Notwithstanding
anything else in this Warrant Certificate or the Warrant Agreement, no Warrant may be exercised unless at the time of exercise
(i) a registration statement covering the shares of Common Stock to be issued upon exercise is effective under the Securities
Act and (ii) a prospectus thereunder relating to the shares of Common Stock is current, except through “cashless exercise”
as provided for in the Warrant Agreement.

 

The
Warrant Agreement provides that upon the occurrence of certain events the number of shares of Common Stock issuable upon exercise
of the Warrants set forth on the face hereof may, subject to certain conditions, be adjusted.  If, upon exercise of
a Warrant, the holder thereof would be entitled to receive a fractional interest in a share of Common Stock, the Company shall,
upon exercise, round down to the nearest whole number of shares of Common Stock to be issued to the holder of the Warrant.

 

Warrant
Certificates, when surrendered at the principal corporate trust office of the Warrant Agent by the Registered Holder thereof in
person or by legal representative or attorney duly authorized in writing, may be exchanged, in the manner and subject to the limitations
provided in the Warrant Agreement, but without payment of any service charge, for another Warrant Certificate or Warrant Certificates
of like tenor evidencing in the aggregate a like number of Warrants.

 

Upon
due presentation for registration of transfer of this Warrant Certificate at the office of the Warrant Agent, a new Warrant Certificate
or Warrant Certificates of like tenor and evidencing in the aggregate a like number of Warrants shall be issued to the transferee(s)
in exchange for this Warrant Certificate, subject to the limitations provided in the Warrant Agreement, without charge except
for any tax or other governmental charge imposed in connection therewith.

 

The
Company and the Warrant Agent may deem and treat the Registered Holder(s) hereof as the absolute owner(s) of this Warrant Certificate
(notwithstanding any notation of ownership or other writing hereon made by anyone), for the purpose of any exercise hereof, of
any distribution to the holder(s) hereof, and for all other purposes, and neither the Company nor the Warrant Agent shall be affected
by any notice to the contrary.  Neither the Warrants nor this Warrant Certificate entitles any holder hereof to any
rights of a stockholder of the Company.

Agreement, through cashless exercise (i) the number of shares of Common Stock that this Warrant is exercisable for would be determined
