CHURCHILL CAPITAL CORP II



and



CONTINENTAL STOCK TRANSFER & TRUST COMPANY



WARRANT AGREEMENT


 


Dated as of October 12, 2020


 


THIS WARRANT AGREEMENT (this
 “Agreement”), dated as of June 11, 2021, is by and between Churchill Capital Corp II, a Delaware corporation (the “Company”),
and Continental Stock Transfer & Trust Company, a New York corporation, as warrant agent (the “Warrant Agent”).


 


WHEREAS, the Company and the
other parties named therein entered into that certain Agreement and Plan of Merger, dated as of October 12, 2020 (the “Merger
Agreement”), pursuant to which, inter alia, a direct, wholly owned subsidiary of the Company will be merged with and
into Albert DE Holdings Inc., a Delaware corporation (“Magnet”), with Magnet surviving as a wholly owned subsidiary
of the Company (the “Merger”), on the terms and subject to the conditions set forth therein (the Merger, together with
the other transactions contemplated by the Merger Agreement, the “Transactions”). Defined terms used and not defined
in this Agreement shall have the meaning ascribed to such terms in the Merger Agreement;


 


WHEREAS, in connection with
the consummation of the Merger, all shares of common stock of Magnet shall be converted into the right to receive 6,000,000 warrants with
the terms set forth in this Agreement (or 5,000,000 such warrants if the Subscription Agreement (as defined in the Merger Agreement) is
terminated in accordance with its terms prior to the closing of the Merger), each such warrant entitling the holders thereof to purchase
one share of Class A Common Stock of the Company, par value $0.0001 per share (the “Common Stock”) (subject to rounding
to avoid fractional warrants), at an exercise price of $11.50 per share, subject to adjustment as described herein and bearing the legend
set forth in Exhibit A hereto (the “GK Warrants”);


 


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 and exercise of the GK Warrants;


 


WHEREAS, the Company desires
to provide for the form and provisions of the GK 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 GK Warrants; and


 


WHEREAS, all acts and things
have been done and performed which are necessary to make the GK 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 GK Warrants, and the Warrant
Agent hereby accepts such appointment and agrees to perform the same in accordance with the express terms and conditions set forth in
this Agreement.


 


2.          Warrants.


 


2.1         Form of GK Warrant. Each GK Warrant shall initially be issued in registered form only. GK Warrants may be represented by
one or more physical definitive certificates or by book entry.


 


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


 


2.3         Registration.


 


2.3.1       
GK Warrant Register. The Warrant Agent shall maintain books (the “Warrant Register”), for the registration
of original issuance and the registration of transfer of the GK Warrants. Upon the initial issuance of the GK Warrants in book-entry form,
the Warrant Agent shall issue and register the GK 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.


 


The physical definitive certificates,
if issued, shall be in the form annexed hereto as Exhibit A, and shall be signed by, or bear the facsimile signature of, the Chairman
of the Board, Chief Executive Officer, Chief Financial Officer, the President or the Secretary or other principal officer of the Company.
In the event the person whose facsimile signature has been placed upon any GK Warrant shall have ceased to serve in the capacity in which
such person signed the GK Warrant before such GK 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 GK Warrant, the Company and the Warrant
Agent may deem and treat the person in whose name such GK Warrant is registered in the Warrant Register (the “Registered Holder”)
as the absolute owner of such GK Warrant and of each GK Warrant represented thereby (notwithstanding any notation of ownership or other
writing on any physical definitive 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        Fractional Warrants. The Company shall not issue fractional GK Warrants and the Company shall round down to the nearest
whole number the number of GK Warrants to be issued to such holder.


 









    2 


     


    

 


3.          Terms and Exercise of GK Warrants.


 


3.1             
GK Warrant Price. Each GK Warrant shall entitle the Registered Holder thereof, subject to the provisions of such GK 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 described in the prior sentence at which shares of Common Stock
may be purchased at the time a GK 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 GK Warrants and, provided further
that any such reduction shall be identical among all of the GK Warrants.


 


3.2             
Duration of GK Warrants. A GK Warrant may be exercised only during the period (the “Exercise Period”)
(A) commencing on the date that is thirty (30) days after the date of this Agreement, and (B) 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 of this Agreement and (y) the liquidation of the Company
in accordance with the Company’s certificate of incorporation, as amended from time to time (the “Expiration Date”);
provided, however, that the exercise of any GK 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. Each GK Warrant not exercised on or
before the Expiration Date shall become null and 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
GK 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 GK Warrants, and, provided further that any such extension shall be identical
in duration among all the GK Warrants.


 


3.3        Exercise
of GK Warrants.


 


3.3.1       
Payment. Subject to the provisions of the GK Warrant and this Agreement, a GK Warrant may be exercised by the Registered
Holder thereof at any time prior to the Expiration Date by surrendering it at the office of the Warrant Agent or at the office of its
successor as Warrant Agent, together with (i) an election to purchase form, duly executed, electing to exercise such GK Warrant; and (ii)
payment in full of the Warrant Price for each full share of Common Stock as to which the GK Warrant is exercised and any and all applicable
taxes due in connection with the exercise of the GK Warrant, the exchange of the GK 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 order of the Warrant Agent or by
wire;


 


(b)          so
long as such GK Warrant is held by Albert UK Holdings 1 Limited (the “Initial Holder”) or a Designated Transferee,
on a “cashless” basis by surrendering the GK 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 GK Warrants, multiplied by the excess of the “Fair
Market Value”, as defined in this subsection 3.3.1(b), over the Warrant Price by (y) the Fair Market Value. Solely for purposes
of this subsection 3.3.1(b), (A) the “Fair Market Value” shall mean the average closing 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 and (B) a “Designated Transferee” shall mean any limited partners, members or stockholders, to
the Initial Holder’s Affiliated investment fund or another Affiliated entity that the Initial Holder or the Initial Holder’s
Affiliates control or manage and each of their respective limited partners, members or stockholders (or an affiliate thereof); or




 


(c)          
as provided in Section 7.4 hereof.


 






    3 


     


    

 


The Warrant Agent shall forward funds received
for warrant exercises in a given month by the 5th business day of the following month by wire transfer to an account designated by the
Company.


 


3.3.2       
Issuance of Shares of Common Stock on Exercise. As soon as practicable after the exercise of any GK 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 GK 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 GK Warrant shall not have
been exercised in full, a new book-entry position or countersigned GK Warrant, as applicable, for the number of shares of Common Stock
as to which such GK 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 GK Warrant and shall have no obligation to settle such GK Warrant exercise unless
a (A) (a) registration statement under the Securities Act covering the issuance of the Common Stock underlying the GK Warrants is then
effective and (b) a prospectus relating thereto is current, subject to the Company’s satisfying its obligations under Section 7.4
or (B) an applicable exemption from registration under the Securities Act is available. No GK Warrant shall be exercisable and the Company
shall not be obligated to issue shares of Common Stock upon exercise of a GK Warrant unless the shares of Common Stock issuable upon such
GK Warrant exercise have 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 GK Warrants. In the event that the conditions in the two immediately preceding
sentences are not satisfied with respect to a GK Warrant, the holder of such GK Warrant shall not be entitled to exercise such GK Warrant
and such GK Warrant may have no value and expire worthless. Subject to Section 4.6 of this Agreement, a Registered Holder of GK
Warrants may exercise its GK Warrants only for a whole number of shares of Common Stock. In no event will the Company be required to net
cash settle the GK Warrant exercise. The Company may require holders of GK Warrants to settle the GK Warrant on a “cashless basis”
pursuant to Section 7.4.2. If, by reason of any exercise of GK Warrants on a “cashless basis,” the holder of any GK
Warrant would be entitled, upon the exercise of such GK 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.


 









    4 


     


    

 


3.3.3       
 Valid Issuance. All shares of Common Stock issued upon the proper exercise of a GK 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 GK Warrant, or book entry position representing such GK 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 GK 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 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 GK 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 GK 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 affect the exercise of the
holder’s GK Warrant, and such holder shall not have the right to exercise such GK 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 4.9% or 9.8% (or such other amount as a 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 GK 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 GK 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 GK Warrant, in determining the number of issued and
outstanding shares of Common Stock, the holder may rely on the number of issued and 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 U.S. Securities and Exchange Commission (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 Warrant Agent setting forth the number
of Common Stock issued and outstanding. For any reason at any time, upon the written request of the holder of the GK 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 GK 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 GK Warrant shall be increased in proportion to such increase in the number of outstanding shares of
Common Stock. A rights offering to holders of shares of 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 shares of 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 shares of Common Stock,
in determining the price payable for shares of 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 GK Warrants are outstanding and unexpired, shall pay a dividend or make a
distribution in cash, securities or other assets to the holders of the shares of Common Stock on account of such shares of Common
Stock (or other shares of the Company’s capital stock into which the GK Warrants are convertible), other than (a) as described
in subsection 4.1.1 above, (b) Ordinary Cash Dividends (as defined below) or (c) in connection with any 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 shares of 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 GK Warrant)
does not exceed $0.50.


 






    6 


     


    

 


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 GK Warrant shall be decreased in proportion to such
decrease in outstanding shares of Common Stock.


 


4.3             
Adjustments in Warrant Price. Whenever the number of shares of Common Stock purchasable upon the exercise of the GK Warrants
is adjusted, 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 GK 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 Section 4.1 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 into another type of entity (other than a consolidation or merger in which the Company is the continuing corporation (and is
not a subsidiary of another entity whose stockholders did not own all or substantially all of the Common Stock of the Company in
substantially the same proportions immediately before such transaction) 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 GK Warrants shall thereafter have the right to purchase and receive, upon the basis and upon the
terms and conditions specified in the GK 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 GK Warrants would have received if such holder had exercised
his, her or its GK Warrant(s) immediately prior to such event (the “Alternative Issuance”); provided, however,
that (i) if the holders of the shares of 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 GK 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 shares of 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 shares of Common Stock 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 GK 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 GK Warrant holder
had exercised the GK Warrant prior to the expiration of such tender or exchange offer, accepted such offer and all of the shares of
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 shares of 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 GK 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, if positive, of (i) the
Warrant Price in effect prior to such reduction minus (ii) (A) the Per Share Consideration (as defined below) minus (B) the
Black-Scholes Warrant Value (as defined below) (which amount determined under this clause (ii) shall not be less than zero). The
 “Black-Scholes Warrant Value” means the value of a GK 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) 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, (2) 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
(3) the assumed risk-free interest rate shall correspond to the U.S. Treasury rate for a period equal to the remaining term of the
GK Warrant. “Per Share Consideration” means (i) if the consideration paid to holders of the shares of 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 GK Warrant.


 






    8 


     


    

 


4.5             
Notices of Changes in GK Warrant. Upon every adjustment of the Warrant Price or the number of shares of Common Stock issuable
upon exercise of a GK 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 GK Warrant, setting forth in reasonable detail the method of calculation and the facts upon which such calculation
is based; provided, however, that no adjustment to the number of shares of Common Stock issuable upon exercise of a GK Warrant
shall be required until cumulative adjustments amount to 1% or more of the number of shares of Common Stock issuable upon exercise of
a GK Warrant as last adjusted; provided, further, that any such adjustments that are not made are carried forward and taken
into account in any subsequent adjustment. Notwithstanding the foregoing, all such carried forward adjustments shall be made (i) in connection
with any subsequent adjustment that (taken together with such carried forward adjustments) would result in a change of at least 1% in
the number of shares of Common Stock issuable upon exercise of a GK Warrant and (ii) on the exercise date of any GK Warrant. Upon the
occurrence of any event specified in Sections 4.1, 4.2, 4.3 or 4 4 in connection with which an adjustment
is made to the Warrant Price or the number of shares of Common Stock issuable upon exercise of a GK Warrant, the Company shall give written
notice of the occurrence of such event to each holder of a GK 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 GK Warrants. If, by reason of any adjustment made pursuant to this Section 4,
the holder of any GK Warrant would be entitled, upon the exercise of such GK 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 GK Warrant. The form of GK Warrant need not be changed because of any adjustment pursuant to this Section 4,
and GK 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 GK 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 GK Warrant that the Company may deem appropriate and that does not affect the substance thereof, and any
GK Warrant thereafter issued or countersigned, whether in exchange or substitution for an outstanding GK 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 GK Warrants in order to
(i) avoid an adverse impact on the GK 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 GK
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 GK Warrants in a manner that is consistent with
any adjustment recommended in such opinion.


 






    9 


     


    

 


5.          
Transfer and Exchange of GK Warrants.


 


5.1             
Registration of Transfer. The Warrant Agent shall register the transfer, from time to time, of any outstanding GK Warrant
upon the Warrant Register, upon surrender of such GK 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 GK Warrant representing
an equal aggregate number of GK Warrants shall be issued and the old GK Warrant shall be cancelled by the Warrant Agent. In the case of
certificated warrants, the GK 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. GK 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 GK Warrants as requested by
the Registered Holder of the GK Warrants so surrendered, representing an equal aggregate number of GK Warrants; provided, however, that
in the event that a GK Warrant surrendered for transfer bears a restrictive legend, the Warrant Agent shall not cancel such GK Warrant
and issue new GK 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 GK 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 GK Warrant.


 


5.4             
Service Charges. No service charge shall be made for any exchange or registration of transfer of GK 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 GK 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 GK Warrants duly executed on behalf of the Company for such
purpose.

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


 


7.1          No Rights as Stockholder. A GK 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.


 





7.2          Lost, Stolen, Mutilated, or Destroyed Warrants. If any GK 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 GK Warrant, include the surrender thereof), issue a new GK Warrant of like denomination, tenor and date as the GK Warrant
so lost, stolen, mutilated or destroyed, and countersigned by the Warrant Agent. Any such new GK Warrant shall constitute a substitute
contractual obligation of the Company, whether or not the allegedly lost, stolen, mutilated or destroyed GK Warrant shall be at any time
enforceable by anyone. Warrant Agent may, at its option, countersign replacement GK Warrants for mutilated certificates upon presentation
thereof without such indemnity.


 


7.3          Reservation of Shares 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 GK Warrants issued pursuant
to this Agreement.


 


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


 


7.4.1       
[Reserved].


 


7.4.2       
Cashless Exercise at Company’s Option. If the shares of Common Stock are at the time of any exercise of a GK 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) and there is no effective registration statement covering the shares issuable upon exercise
of the GK Warrants at such time, the Company may, at its option, require holders of GK Warrants who exercise GK Warrants to exercise such
GK Warrants on a “cashless basis” in accordance with Section 3(a)(9) of the Securities Act (or any successor statute) or such
other applicable 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 GK Warrants, multiplied by the excess of the “Fair Market Value” (as
defined below) over the Warrant Price by (y) the Fair Market Value. Solely for purposes of this section 7.4.2, “Fair Market Value”
shall mean the average closing price of the Common Stock for the ten (10) trading days ending on the third trading day prior to the date
that notice of exercise is sent to the Warrant Agent from the holder of such GK Warrants or its securities broker or intermediary, and
if the Company does not so elect, the Company agrees to use its best efforts to register or qualify for sale the shares of Common Stock
issuable upon exercise of the GK Warrant under the blue sky laws of the state of residence of the exercising GK 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 GK Warrants, but the Company and the
Warrant Agent shall not be obligated to pay any transfer taxes in respect of the GK 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 ninety
(90) days after it has been notified in writing of such resignation or incapacity by the Warrant Agent or by the holder of a GK Warrant
(who shall, with such notice, submit his GK Warrant for inspection by the Company), then the holder of any GK 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 authorized under applicable laws to exercise
the powers of a transfer agent 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 Company’s transfer agent for the shares of Common Stock not later than the effective
date of any such appointment.


 


8.2.3       
Merger or Consolidation of Warrant Agent. Any entity into which the Warrant Agent may be merged or with which it may be
consolidated or any entity 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

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 Chairman of the Board, Chief Executive Officer, Chief Financial Officer, the President or
the Secretary or other principal officer 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, or its representatives’, gross negligence,
willful misconduct, bad faith or material breach of this Agreement. 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, or its representatives’, gross negligence,
willful misconduct, bad faith or material breach of this Agreement.


 


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 GK 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 GK 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 GK 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 GK 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 GK Warrants.


 






    13


     


    

 


8.6

in, or to any distribution of, the Trust Account (as defined in that certain Investment Management Trust Agreement, dated as of February
13, 2020, 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.


 


9.1

Churchill Capital Corp II

Incorporated Under the Laws of the State of Delaware


 


CUSIP [●]


 


Warrant Certificate


 


This Warrant Certificate certifies that,
or registered assigns, is the registered holder of warrant(s) evidenced hereby (the “GK Warrants” and each, a “GK
Warrant”) to purchase shares of Class A common stock, $0.0001 par value per share (“Common Stock”), of Churchill
Capital Corp II, a Delaware corporation (the “Company”). Each whole GK 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 “Warrant 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 Warrant 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 whole GK 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 GK Warrant. If,
upon the exercise of GK Warrants, a holder would be entitled to receive a fractional interest in a share of Common Stock, the Company
will, upon exercise, round down to the nearest whole number of the number of shares of Common Stock to be issued to the holder. The number
of shares of Common Stock issuable upon exercise of the GK Warrants is subject to adjustment upon the occurrence of certain events as
set forth in the Warrant Agreement. The initial Warrant Price per share of Common Stock for any GK Warrant is equal to $11.50 per share.
The Warrant Price is subject to adjustment upon the occurrence of certain events as set forth in the Warrant Agreement.


 


[Form of Warrant]


 






     


     


    

 


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


 


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 by and construed
in accordance with the internal laws of the State of New York.

[Form of Warrant Certificate]


 


[Reverse]


 


The GK Warrants evidenced by this Warrant Certificate
are part of a duly authorized issue of GK 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 (or successor warrant
agent) (collectively, 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 GK 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.


 


GK Warrants may be exercised at any time during
the Exercise Period set forth in the Warrant Agreement. The holder of GK 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 Warrant Price as specified in the Warrant Agreement (or through “cashless exercise” as provided
for in the Warrant Agreement) at the designated office of the Warrant Agent. In the event that upon any exercise of GK Warrants evidenced
hereby the number of GK Warrants exercised shall be less than the total number of GK 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 GK Warrants not exercised.


 


Notwithstanding anything else in this Warrant
Certificate or the Warrant Agreement, no GK Warrant may be exercised unless at the time of exercise (A) (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 or (B) an applicable exemption from registration under the Securities Act is available, 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 GK Warrants set forth on the face hereof may, subject
to certain conditions, be adjusted. If, upon exercise of a GK 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 GK Warrant.


 


Warrant Certificates, when surrendered at the
designated 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 GK
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 GK 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 third-party charges 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 GK Warrants
nor this Warrant Certificate entitles any holder hereof to any rights of a stockholder of the Company.
