between

 

NEBULA ACQUISITION CORPORATION

 

and

 

AMERICAN STOCK TRANSFER & TRUST
COMPANY, LLC

 

THIS WARRANT AGREEMENT (this “Agreement”),
dated as of ______, 2017, is by and between Nebula Acquisition Corporation, a Delaware corporation (the “Company”),
and American Stock Transfer & Trust Company, LLC, a New York limited liability trust company, as warrant agent (the “Warrant
Agent”, also referred to herein as the “Transfer Agent”).

 

WHEREAS, on ______, 2017, the Company entered
into that certain Private Placement Warrants Purchase Agreement with Nebula Holdings, LLC, a Delaware limited liability company
(the “Sponsor”), pursuant to which the Sponsor agreed to purchase an aggregate of 4,666,667 warrants
(or up to 5,166,667 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 $1.50 per Private Placement Warrant; and

 

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, but are not obligated to, loan the Company funds as the Company may
require, 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-third of one Public Warrant (as defined below) (the “Units”)
and, in connection therewith, has determined to issue and deliver up to 9,583,334 warrants (including up to 1,250,000 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 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-_______ (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.

 

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 Deutsche Bank Securities Inc. and Goldman Sachs & Co. LLC, as representatives 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	 

     

    

 

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-third 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.

 

2.6
Private Placement Warrants.

 

2.6.1
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; 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 any affiliates of the Sponsor;

 

(b)
in the case of an individual, 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, by virtue of laws of descent and distribution upon death of the individual;

 

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

 

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

 

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

 

(g)  
by virtue of the laws of the state of Delaware or the Sponsor’s limited liability company agreement upon dissolution of the
Sponsor; or

 

(i)     
in the event of the Company’s liquidation, merger, capital stock exchange, reorganization 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 (g), these transferees (the “Permitted Transferees”) must enter into a written agreement
agreeing to be bound by the transfer restrictions in this Agreement.

 

    	 	3	 

     

    

 

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”), or (ii) the date that is twelve (12) months
from the date of the closing of the Offering, and terminating at 5:00 p.m., New York City time on the earlier to occur of: (x) the
date that is five (5) years after the date on which the Company completes its Business Combination, (y) the liquidation
of the Company in accordance with the Company’s amended and restated certificate of incorporation, as amended from time to
time, if the Company fails to complete a Business Combination, or (z) other than with respect to the Private Placement Warrants
then held by the Sponsor or its Permitted Transferees, the 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) (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 outstanding Warrant (other than a Private Placement Warrant 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 shares of Common Stock, as follows:

 

(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 6.3, 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;

 

    	 	4	 

     

    

 

(c)  
with respect to any Private Placement Warrant, so long as such Private Placement Warrant is held by the Sponsor or its Permitted
Transferees, 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 Private Placement 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 from registration or qualification 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. 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.

 

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.

 

    	 	5	 

     

    

 

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 and any of its affiliates
or any other person subject to aggregation with such person for purposes of the “beneficial ownership” test under Section
13 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), or any “group” (within the
meaning of Section 13 of the Exchange Act) of which such person is or may be deemed to be a part, would beneficially own (within
the meaning of Section 13 of the Exchange Act) (or to the extent that for any reason the equivalent calculation under Section 16
of the Exchange Act and the rules and regulations thereunder would result in a higher ownership percentage, such higher percentage
would be) in excess of 4.8% or 9.8% (as specified by the holder) (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 or any such other person or group 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 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.

 

    	 	6	 

     

    

 

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 amend the Company’s amended and restated certificate
of incorporation to modify the substance or timing of the Company’s obligation to redeem 100% of the shares of Common Stock
included in the Units sold in the Offering if the Company does not complete the Business Combination within the time period set
forth in the Company’s amended and restated certificate if incorporation, or, (e) in connection with the redemption
of the shares of Common Stock included in the Units sold in the Offering upon the failure of the Company to complete its initial
Business Combination and any subsequent distribution of its assets upon its liquidation (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 $0.50 (being 5% 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 (x) 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 (y) the denominator of which shall be the number of shares of Common Stock so purchasable immediately thereafter.

 

    	 	7	 

     

    

 

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 entity or conversion of the Company as another entity (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.

 

    	 	8	 

     

    

 

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.

 

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.

 

    	 	9	 

     

    

 

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, 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; provided, however, that under no circumstances shall the Warrants be adjusted
pursuant to this Section 4.8 as a result of any issuance of securities in connection with a Business Combination. 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, in the case of certificated warrants, 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.
In the case of certificated warrants, 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
Fractional Warrants. The Warrant Agent shall not be required to effect any registration of transfer or exchange which shall
result in the issuance of a warrant certificate or book-entry position for a fraction of a warrant, except as part of the Units.

 

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. Subject to Section 6.4 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 6.2 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 Business 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 6.2 below) or the Company has elected to require the exercise of the Warrants on a “cashless
basis” pursuant to subsection 3.3.1; provided, however, that if and when the Public Warrants become redeemable by
the Company, the Company may not exercise such redemption right if the issuance of shares of Common Stock upon exercise of the
Public Warrants is not exempt from registration or qualification under applicable state blue sky laws or the Company is unable
to effect such registration or qualification.

 

    	 	10	 

     

    

 

6.2
Date Fixed for, and Notice of, Redemption. In the event that the Company elects to redeem all of the Warrants, the Company
shall fix a date for the redemption (the “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.

 

6.3
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 6.2 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.

 

6.4
Exclusion of Private Placement Warrants. The Company agrees that the redemption rights provided in this Section 6
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 6.3. 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.

 

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 a stockholder in respect of the meetings of stockholders or the election of
directors of the Company or any other matter.

 

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.

 

    	 	11	 

     

    

 

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 reasonable 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 reasonable 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
rule) 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.

 

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 rule), 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 rule) as described in subsection 7.4.1 and (ii) in the event the Company so elects,
the Company shall 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. If the Company does not elect at the time of exercise to require a holder of Public Warrants who exercises Public
Warrants to exercise such Public Warrants on a “cashless basis,” it agrees to use its best efforts to register or qualify
for sale the Common Stock issuable upon exercise of the Public Warrant under the blue sky laws of the state of residence in those
states in which the Public Warrants were initially offered by the Company 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.

 

    	 	12	 

     

    

 

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.

 

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.

 

    	 	13	 

     

    

 

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.

9.3
Applicable Law. The validity, interpretation, and performance of this Agreement and of the Warrants shall be governed in
all respects by the laws of the State of New York, without giving effect to conflicts of law principles that would result in the
application of the substantive laws of another jurisdiction. The Company hereby agrees that any action, proceeding or claim against
it arising out of or relating in any way to this Agreement shall be brought and enforced in the courts of the State of New York
or the United States District Court for the Southern District of New York, and irrevocably submits to such jurisdiction, which
jurisdiction shall be exclusive. The Company hereby waives any objection to such exclusive jurisdiction and that such courts represent
an inconvenient forum.

 

9.4
Persons Having Rights under this Agreement. Nothing in this Agreement shall be construed to confer upon, or give to, any
person or corporation other than the parties hereto and the Registered Holders of the Warrants any right, remedy, or claim under
or by reason of this Agreement or of any covenant, condition, stipulation, promise, or agreement hereof. All covenants, conditions,

including any amendment to increase the Warrant Price or shorten the Exercise Period and any amendment to the terms of only the

Period pursuant to Sections 3.1 and 3.2, respectively, without the consent of the Registered Holders.

 

9.9
Severability. This Agreement shall be deemed severable, and the invalidity or unenforceability of any term or provision

NEBULA ACQUISITION CORPORATION

CUSIP 629076 118

 

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 Nebula
Acquisition Corporation, 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 in lawful money (or through “cashless exercise”
as provided for in the Warrant Agreement) of the United States of America 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. The number of shares of Common Stock issuable upon exercise of the
Warrants is subject to adjustment upon the occurrence of certain events set forth in the Warrant Agreement.

 

The initial Exercise Price per share of
Common Stock for any Warrant is equal to $11.50 per share.  The Exercise Price is subject to adjustment upon the occurrence
of certain events 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 is hereby made to the further
provisions of this Warrant Certificate set forth on the reverse hereof and such further provisions shall for all purposes have
the same effect as though fully set forth at this place.

 

This Warrant Certificate shall not be valid
unless countersigned by the Warrant Agent, as such term is used in the Warrant Agreement.

 

This Warrant Certificate shall be governed

[Form of Warrant Certificate]

 

[Reverse]

 

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           ,
2018 (the “Warrant Agreement”), duly executed and delivered by the Company to American Stock Transfer &
Trust Company, LLC, a New York limited liability trust company, 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) 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.

new Warrant Certificate representing the remaining balance of such shares of Common Stock be registered in the name of                ,

Warrant Certificate be delivered to                ,

In the event that the Warrant has been called
for redemption by the Company pursuant to Section 6 of the Warrant Agreement and the Company has required cashless
exercise pursuant to Section 6.3 of the Warrant Agreement, the number of shares of Common Stock that this Warrant is
exercisable for shall be determined in accordance with subsection 3.3.1(b) and Section 6.3 of the Warrant
Agreement.

 

In the event that the Warrant is a Private
Placement Warrant that is to be exercised on a “cashless” basis pursuant to subsection 3.3.1(c) of the
Warrant Agreement, the number of shares of Common Stock that this Warrant is exercisable for shall be determined in accordance
with subsection 3.3.1(c) of the Warrant Agreement.

 

In the event that the Warrant is to be exercised
on a “cashless” basis pursuant to Section 7.4 of the Warrant Agreement, the number of shares of Common
Stock that this Warrant is exercisable for shall be determined in accordance with Section 7.4 of the Warrant Agreement.

 

In the event that the Warrant may be exercised,
to the extent allowed by the Warrant Agreement, through cashless exercise (i) the number of shares of Common Stock that this
Warrant is exercisable for would be determined in accordance with the relevant section of the Warrant Agreement which allows for
such cashless exercise and (ii) the holder hereof shall complete the following: The undersigned hereby irrevocably elects
to exercise the right, represented by this Warrant Certificate, through the cashless exercise provisions of the Warrant Agreement,
to receive shares of Common Stock. If said number of shares is less than all of the shares of Common Stock purchasable hereunder
(after giving effect to the cashless exercise), the undersigned requests that a new Warrant Certificate representing the remaining
balance of such shares of Common Stock be registered in the name of                ,
whose address is                    and that such
Warrant Certificate be delivered to                ,
whose address is                .

real or personal, or any part of the proceeds arising from any sale of any such property, from attachment, levy or sale under
execution, or providing for any stay of execution, exemption from civil process, or extension of time for payment; and Maker agrees
that any real estate that may be levied upon pursuant to a judgment obtained by virtue hereof or any writ of execution issued
hereon, may be sold upon any such writ in whole or in part in any order desired by Payee.

 

8. Unconditional
Liability. Maker hereby waives all notices in connection with the delivery, acceptance, performance, default, or enforcement

party, and shall not be affected in any manner by any indulgence, extension of time, renewal, waiver or modification granted or
consented to by Payee, and consents to any and all extensions of time, renewals, waivers, or modifications that may be granted
by Payee with respect to the payment or other provisions of this Note, and agrees that additional makers, endorsers, guarantors,
