(ii) filings required by applicable state or federal securities laws, (iii) the filings required in accordance with the BCA and Warrant Agreement, (iv) those required by Nasdaq, including with respect to obtaining stockholder approval, and
(v) the failure of which to obtain would not reasonably be expected to have, individually or in the aggregate, a Material Adverse Effect or have a material adverse effect on the Issuer’s ability to consummate the transactions contemplated

 g. The authorized capital stock of the Issuer consists of (i) 1,000,000
shares of preferred stock, par value $0.0001 per share (“Preferred Stock”), (ii) 250,000,000 Class A Shares and (iii) 20,000,000 shares of Class B common stock, par value $0.0001 per share (“Class B

h. The Issuer has not received any written communication from a governmental entity alleging that the Issuer is not in
compliance with or is in default or violation of any applicable law, except where such non-compliance, default or violation would not, individually or in the aggregate, reasonably be expected to have a
Material Adverse Effect. 
 i. The issued and outstanding Class A Shares are registered pursuant to Section 12(b)
of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), and are listed on Nasdaq. There is no suit, action, proceeding or investigation pending or, to the Issuer’s knowledge, threatened against the Issuer by
Nasdaq or the Commission with respect to any intention by such entity to deregister the Class A Shares or prohibit or terminate the listing of the Class A Shares on Nasdaq. The Issuer has taken no action that is designed to terminate the
registration of the Class a Shares under the Exchange Act. 
 j. Assuming the accuracy of Ardour’s representations
and warranties set forth in Section 4, no registration under the Securities Act is required for the offer and sale of the Securities by the Issuer to Ardour in the manner contemplated by this Subscription Agreement. 

k. Neither the Issuer nor any person acting on its behalf has engaged or will engage in any form of general solicitation or
general advertising (within the meaning of Regulation D of the Securities Act) in connection with any offer or sale of the Securities.

of each form, report, statement, schedule, prospectus, proxy, registration statement and other document, if any, filed by the Issuer with the Commission since its initial registration of the Class A Shares (the “SEC
Documents”), which SEC Documents, as of their respective filing dates, complied in all material respects with the applicable requirements of the Exchange Act and the applicable rules and regulations of the Commission promulgated thereunder.
None of the SEC Documents filed under the Exchange Act (except to the extent that information contained in any SEC Document has been superseded by a later timely filed SEC Document) contained, when filed, any untrue statement of a material fact or
omitted to state a material fact required to be stated therein or necessary to make the statements therein not misleading, in the case of any SEC Document that is a registration statement, or included,

 
when filed, any untrue statement of a material fact or omitted to state a material fact necessary to make the statements therein, in the light of the circumstances under which they were made, not
misleading, in the case of all other SEC Documents; provided, that, with respect to the proxy statement to be filed by the Issuer with respect to the Transaction or any of its affiliates included in any SEC Document or filed as an exhibit thereto,
the representation and warranty in this sentence is made to the Issuer’s knowledge. The Issuer has timely filed each report, statement, schedule, prospectus and registration statement that the Issuer was required to file with the Commission
since its inception. There are no material outstanding or unresolved comments in comment letters from the Staff of the Commission with respect to any of the SEC Documents. 

m. There is no (i) proceeding pending, or, to the Issuer’s knowledge, threatened against the Issuer, or

contemplated herein, will not conflict with or result in a breach or violation of any of the terms or provisions of, or constitute a default under, or result in the creation or imposition of any lien, charge or encumbrance upon any of the property
or assets of it pursuant to the terms of (i) any indenture, mortgage, deed of trust, loan agreement, lease, license or other agreement or instrument to which it is a party or is bound or to which any of the property or assets of it is subject,
which would reasonably be expected to have a material adverse effect on the business, properties, financial condition, stockholders’ equity or results of operations of it, taken as a whole (a “Ardour Material Adverse Effect”),

and its professional advisor(s), if any, have had the full opportunity to ask such questions, receive such answers and obtain such information as it and such undersigned’s professional advisor(s), if any, have deemed necessary to make an

risk of a total loss of Ardour’s investment in the Issuer. It acknowledges specifically that a possibility of total loss exists. 

k. It understands and agrees that no federal or state agency has passed upon or endorsed the merits of the offering of the
Securities or made any findings or determination as to the fairness of this investment.

obligations of the parties hereto shall terminate without any further liability on the part of any party in respect thereof, upon the earliest to occur of (a) such date and time the BCA is validly terminated in accordance with its terms,
(b) upon the mutual written agreement of each of the parties hereto to terminate this Subscription Agreement, and (c) at the election of Ardour, on or after the date that is 180 days after the date hereof (the “End Date”)

9. Trust Account Waiver. Ardour and the Financial Advisor each acknowledge that the Issuer is a blank check company with the powers and
privileges to effect a merger, asset acquisition, reorganization or similar business combination involving the Issuer and businesses or assets. Ardour and the Financial Advisor each further acknowledge that, as described in the Issuer’s
prospectus relating to its initial public offering dated October 19, 2020 (the “Prospectus”), available at www.sec.gov, substantially all of the Issuer’s assets consist of the cash proceeds of the Issuer’s initial
public offering and private placements of its securities, and substantially all of those proceeds have been deposited in a trust account (the “Trust Account”) for the benefit of the Issuer, its public stockholders and the
underwriters of the Issuer’s initial public offering. The cash in the Trust Account may be disbursed only for the purposes set forth in the Prospectus, except with respect to interest earned on the funds held in the Trust Account that may be
released to the Issuer to pay its tax obligations, if any. For and in consideration of the Issuer entering into this Subscription Agreement, the receipt and sufficiency of which are hereby acknowledged, Ardour and the Financial Advisor each, on
behalf of itself and its representatives, hereby irrevocably waives all right, title and interest, or claim of any kind they have or may have in the future arising out of this Subscription Agreement, in or to any monies held in the Trust Account,
and agrees not to seek recourse against the Trust Account as a result of, or arising out of, this Subscription Agreement; provided, however, that nothing in this Section 9 shall be deemed to limit Ardour or the Financial Advisor’s
right, title, interest or claim to the Trust Account by virtue of Ardour or the Financial Advisor’s record or beneficial ownership of securities of the Issuer acquired by any means other than pursuant to this Subscription Agreement, including
but not limited to any redemption right with respect to such securities of the Issuer.

Advisor may not transfer or assign all or a portion of its rights under this Subscription Agreement other than to a fund or account managed by the same investment manager as Ardour and the Financial Advisor, without the prior consent of the Issuer;
provided that such transferee or assignee agrees in writing to be bound by and subject to the terms and conditions of this Subscription Agreement, makes the representations and warranties in Section 7 and completes Schedule A hereto. In the
event of such a transfer or assignment, Ardour and the Financial Advisor shall update Schedule B to provide the information required therein 

d. Ardour and the Financial Advisor hereby acknowledges and agrees that the Issuer may incur indebtedness pursuant to loans

further acknowledges and agrees that up to $1,500,000 of such Loans may be convertible into warrants at a price of $1.00 per warrant at the option of the lender and that any such conversion shall not constitute a breach or violation of any of the
terms or provisions of, or constitute a default under, this Subscription Agreement. 
 e. All the agreements, representations
and warranties made by each party hereto in this Subscription Agreement shall survive the Closing. For the avoidance of doubt, if for any reason the Closing does not occur immediately following the consummation of the Transaction, all
representations, warranties, covenants and agreements of the parties hereto shall survive the consummation of the Transaction and remain in full force and effect.

 ANNEX A 
  

Final Form 
 WARRANT
AGREEMENT 
 by and between 

DECARBONIZATION PLUS ACQUISITION CORPORATION, 

and 
 CONTINENTAL STOCK
TRANSFER & TRUST COMPANY 
 THIS WARRANT AGREEMENT (this “Agreement”), dated as of [_______], 2021, is by
and between Decarbonization Plus Acquisition Corporation, a Delaware corporation (the “Company”), and Continental Stock Transfer & Trust Company, a New York corporation, as warrant agent (the “Warrant
Agent”, also referred to herein as the “Transfer Agent”). 
 WHEREAS, on February 8, 2021, the
Company entered into that certain Business Combination Agreement and Plan of Reorganization (the “BCA”), by and among the Company, DCRB Merger Sub Inc., a Delaware corporation (“Merger Sub”) and Hyzon
Motors Inc. (“Hyzon”), pursuant to which, among other things, Merger Sub will merge with and into the Hyzon, with Hyzon surviving the merger as a wholly owned subsidiary of the Company; 

WHEREAS, concurrent with the signing of the BCA, the Company entered into a Subscription Agreement with ACP Mgmt Corp., a Delaware corporation
(“Ardour”), Ardour Capital Investments LLC, a Delaware limited liability company (the “Financial Advisor”) and Hyzon (the “Subscription Agreement”), pursuant to which the
Company agreed to issue the Warrants (as defined therein). 
 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; 

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. 
 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 No Fractional Warrants. The Company shall not issue fractional Warrants. 

2.5 Rights Under Other Documents. The Warrants will be issued pursuant to the Subscription Agreement, and the Registered Holder is
entitled to the rights and benefits set forth in such agreement (as such agreement may be amended, modified or restated in accordance with their terms). 

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 $2.20 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 

  
 -2- 

 
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; and provided, further, that, in the
event that the Company lowers the “Warrant Price” of any of the Public Warrants, the Warrant Price shall be lowered on an equivalent basis. For purposes hereof, “Public Warrants” means, collectively, the redeemable warrants
originally issued by the Company as part of the units in the Company’s initial public offering, the warrants issued in a private placement simultaneously with the closing of such initial public offering and any other warrants issued by the
Company prior to, substantially contemporaneously with, or otherwise in connection with, the Closing (as defined in the BCA). 
 3.2
Duration of Warrants. A Warrant may be exercised only during the period (the “Exercise Period”) commencing on the date that is thirty (30) days after the Closing , and terminating at 5:00 p.m., New York City time
on the earlier to occur of: (w) the date that is five (5) years after the Closing, (x) the liquidation of the Company, (y) the Redemption Date (as defined below) as provided in Section 6.3 hereof, or
(z) the Alternative Redemption Date (as defined below) as provided in Section 6.2 hereof (the “Expiration Date”). Except with respect to the right to receive the Redemption Price (as defined below) or the
Alternative Redemption Price, in the event of a redemption as set forth in Section 6 hereof (and subject to the terms and conditions thereof), each Warrant 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; and provided, further, that, in the event that the Company extends the duration of any of the Public Warrants, the duration of the Warrants shall be extended on an equivalent basis. 

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 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; 

  
 -3- 

 (b) in the event that the Warrants are to be exercised upon a “cashless basis,”
pursuant to the terms hereof, 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
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), the “Fair Market Value” shall
mean the 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; or 
 (c) as provided in Section 6.2 hereof with respect to a
Make-Whole Exercise. 
 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 certificate 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 and is surrendered to the Company, a countersigned Warrant for the number of
shares of Common Stock as to which such Warrant shall not have been exercised. In no event will the Company be required to net cash settle the Warrant exercise. The Company may require holders of the Warrants to settle Warrant exercises 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. Notwithstanding the foregoing or anything else to the contrary contained
herein, the Registered Holder shall not be required to surrender any Warrant to the Company until the Registered Holder has purchased all of the shares available thereunder and such Warrant has been exercised in full, in which case the Registered
Holder shall surrender such Warrant to the Company for cancellation within three (3) trading days following the date the final subscription form is delivered to the Company. Execution and delivery of a subscription form with respect to a
partial exercise shall have the same effect as cancellation of the original Warrant and issuance of a new Warrant evidencing the right to purchase the remaining number of shares of Common Stock. 

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 Exercise/Issuance. The
“date of exercise” of any Warrant shall be defined as the date that the subscription form, as set forth in the Warrant, completed and executed, is sent by facsimile or electronic mail to the Company, provided that payment of the Warrant
Price, if applicable, is satisfied as soon as practicable thereafter but no later than two (2) trading days after the date of exercise. In the event that the Warrant Price (if applicable) set forth in the subscription form is not paid to the
Company by the deadline therefor, as set forth in the preceding sentence, the date of exercise shall be such date as such Warrant Price is received by the Company. Each person in whose name any certificate for shares of Common Stock is to be issued
shall for all purposes be deemed to have become the holder of record of such shares of Common Stock on the date of exercise of the Warrant, irrespective of the date of delivery of such certificate, except that, if the date of such exercise is a date
when the share transfer books of the Company 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 are open. 

  
 -4- 

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

  
 -5- 

 4. Adjustments. 

4.1 Stock Dividends. 

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

4.1.2 Extraordinary Dividends. If the Company, at any time while the Warrants are outstanding and unexpired, shall pay a dividend or
make a distribution in cash, securities or other assets to the holders of the Common Stock on account of such shares of Common Stock (or other shares of the Company’s capital stock into which the Warrants are convertible), other than
(a) as described in subsection 4.1.1 above, or (b) Ordinary Cash Dividends (as defined below) (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 Company’s initial public 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. 

  
 -6- 

 4.3 Adjustments in Exercise and Redemption Trigger Prices. 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. 
 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 subsection 4.1.1 or subsection 4.1.2 or
Section 4.2 hereof or that solely affects the par value of such shares of Common Stock), or in the case of any merger or consolidation of the Company with or into another corporation (other than a consolidation or merger in
which the Company is the continuing corporation and that does not result in any reclassification or reorganization of the outstanding shares of Common Stock), or in the case of any sale or conveyance to another corporation or entity of the assets or
other property of the Company as an entirety or substantially as an entirety in connection with which the Company is dissolved, the holders of the Warrants shall thereafter have the right to purchase and receive, upon the basis and upon the terms
and conditions specified in the Warrants and in lieu of the shares of Common Stock of the Company immediately theretofore purchasable and receivable upon the exercise of the rights represented thereby, the kind and amount of shares of stock or other
securities or property (including cash) receivable upon such reclassification, reorganization, merger or consolidation, or upon a dissolution following any such sale or transfer, that the holder of the Warrants would have received if such holder had
exercised his, her or its Warrant(s) immediately prior to such event (the “Alternative Issuance” ); provided, however, that (i) if the holders of the Common Stock were entitled to exercise a right of
election as to the kind or amount of securities, cash or other assets receivable upon such consolidation or merger, then the kind and amount of securities, cash or other assets constituting the Alternative Issuance for which each Warrant shall
become exercisable shall be deemed to be the weighted average of the kind and amount received per share by the holders of the Common Stock in such consolidation or merger that affirmatively make such election, and (ii) if a tender, exchange or
redemption offer shall have been made to and accepted by the holders of the Common Stock 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 

  
 -7- 

 
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. 

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. 

  
 -8- 

 4.7 Form of Warrant. The form of Warrant need not be changed because of any
adjustment pursuant to this Section 4, and Warrants issued after such adjustment may state the same Warrant Price and the same number of shares of Common Stock as is stated in the Warrants initially issued pursuant to this
Agreement; provided, however, that the Company may at any time in its sole discretion make any change in the form of Warrant that the Company may deem appropriate and that does not affect the substance thereof, and any Warrant thereafter issued or
countersigned, whether in exchange or substitution for an outstanding Warrant or otherwise, may be in the form as so changed. 
 4.8
Other Events. In case any event shall occur affecting the Company as to which none of the provisions of the preceding subsections of this Section 4 are strictly applicable, but which would require an adjustment to
the terms of the Warrants in order to (i) avoid an adverse impact on the Warrants and (ii) effectuate the intent and purpose of this Section 4 (including, without limitation, any event which requires an adjustment
to the terms of the Public Warrants), 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 avoid such adverse impact and/or to effectuate the intent and purpose of this Section 4 and, if they determine that an adjustment is necessary,
the terms of such adjustment (which shall be equivalent to any adjustment to the Public Warrants). The Company shall adjust the terms of the Warrants in a manner that is consistent with any adjustment recommended in such opinion. 

5. Transfer and Exchange of Warrants. 

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

5.2 Procedure for Surrender of Warrants. Warrants may be surrendered to the Warrant Agent, together with a written request for exchange
or transfer, and thereupon the Warrant Agent shall issue in exchange therefor one or more new Warrants as requested by the Registered Holder of the Warrants so surrendered, representing an equal aggregate number of Warrants; provided, however, that
in the event that a Warrant surrendered for transfer bears a restrictive legend, the Warrant Agent shall not cancel such Warrant and issue new Warrants in exchange thereof until the Warrant Agent has received an opinion of counsel for the Company
stating that such transfer may be made and indicating whether the new Warrants must also bear a restrictive legend. 
 5.3 Transfers of
Fractions of Warrants. The Warrant Agent shall not be required to effect any registration of transfer or exchange of Warrants which would require the issuance of a warrant certificate or book-entry position for a fraction of a warrant. 

  
 -9- 

 5.4 Service Charges. No service charge shall be made for any exchange or registration
of transfer of Warrants. 
 5.5 Accredited Investors. The Warrants may only be transferred to (i) an “accredited
investor” (as defined in Rule 501(a)(1), (a)(2), (a)(3), (a)(7) or (a)(8) under the Securities Act) or (ii) a “qualified institutional buyer” (as defined in Rule 144A(a) under the Securities Act). 

5.6 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. 
 6. Redemption. 

6.1 Redemption of Warrants for Cash When the Price Per Share of Common Stock Equals or Exceeds $18.00. Not less than all of the
outstanding Warrants may be redeemed, at the option of the Company, at any time while they are exercisable and prior to their expiration, at the office of the Warrant Agent, upon notice to the Registered Holders of the Warrants, as described in
Section 6.3 below, at a Redemption Price of $0.01 per Warrant, 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 (i) the Company is contemporaneously taking, or has taken, the same action in respect of all the Public Warrants, and (ii) there is an effective registration statement covering the resale by the
Registered Holder of all of the shares of Common Stock issuable upon exercise of the Warrants, and a current prospectus relating thereto, available throughout the 30-day Redemption Period (as defined in
Section 6.3 below). 
 6.2 Redemption of Warrants When the Price Per Share of Common Stock Equals or Exceeds
$10.00. Not less than all of the outstanding Warrants may be redeemed, at the option of the Company, at any time while they are exercisable and prior to their expiration, at the office of the Warrant Agent, upon notice to the Registered Holders
of the Warrants, as described in Section 6.3 below, at a Redemption Price of $0.10 per Warrant, provided that the last sale price of the Common Stock equals or exceeds $10.00 per share (subject to adjustment in compliance
with Section 4 hereof), on the trading day prior to the date on which notice of the redemption is given . During the 30-day Redemption Period (as defined in Section 6.3 below) in
connection with a redemption pursuant to this Section 6.2, Registered Holders of the Warrants may elect to exercise their Warrants on a “cashless basis” pursuant to subsection 3.3.1 and receive a number of
shares of Common Stock determined by reference to the table set forth in Section 6.2 of the Warrant Agreement, dated October 19, 2020, by and between the Company and the Warrant Agent (the “Table”), as
equitably adjusted to reflect the Exercise Price of the Warrants as compared to the exercise price of the Public Warrants, based on the Redemption Date (as defined below) and the “Redemption Fair Market Value” (as such term is defined in
this Section 6.2) (a “Make-Whole Exercise”). Solely for purposes of this Section 6.2, the “Redemption Fair Market Value” shall mean the average reported last sale
price of the Common Stock for the ten trading days immediately following the date on which notice of redemption pursuant to this Section 6.2 

  
 -10- 

 
is sent to the Registered Holders. In connection with any redemption pursuant to this Section 6.2, the Company shall provide the Registered Holders with the Redemption
Fair Market Value no later than one Business Day after the ten trading day period described in the definition of “Redemption Fair Market Value” above ends. 

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

The stock prices set forth in the column headings of the Table shall be adjusted as of any date on which the number of shares issuable upon
exercise of a Warrant is adjusted pursuant to Section 4. The adjusted stock prices in the column headings shall equal the stock prices immediately prior to such adjustment, multiplied by a fraction, the numerator of which
is the number of shares deliverable upon exercise of a Warrant immediately prior to such adjustment and the denominator of which is the number of shares deliverable upon exercise of a Warrant as so adjusted. The number of shares in the Table shall
be adjusted in the same manner and at the same time as the number of shares issuable upon exercise of a Warrant. 
 In no event shall the
Warrants be exercisable in connection with a Make-Whole Exercise for more than 0.361 shares of Common Stock per whole warrant (as equitably adjusted to reflect the Exercise Price of the Warrants as compared to the exercise price of the Public
Warrants and subject to further adjustment). 
 6.3 Date Fixed for, and Notice of, Redemption; Redemption Price. In the event that
the Company elects to redeem the Warrants pursuant to Sections 6.1 or 6.2 hereof, 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. As
used in this Agreement, “Redemption Price” shall mean the price per Warrant at which any Warrants are redeemed pursuant to Sections 6.1 or 6.2 hereof. 

6.4 Exercise After Notice of Redemption. The Warrants may be exercised for cash (or, if in connection with a redemption pursuant to
Section 6.2 hereof, on a “cashless basis” in accordance with such section) at any time after notice of redemption shall have been given by the Company pursuant to Section 6.3 hereof and
prior to the Redemption Date. On and after the Redemption Date, the Registered Holder of the Warrants shall have no further rights hereunder except to receive, upon surrender of the Warrants, the Redemption Price, or to receive any shares of Common
Stock issuable in respect of any exercises of the Warrants effected prior to the Redemption Date, as applicable.

 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 stockholders 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. 

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

7.4.1 Registration of the Common Stock. The Company agrees that as soon as practicable, but in no event later than fifteen
(15) Business Days after the closing of its initial Business Combination, it shall use its best efforts to file with the Commission a registration statement for the registration, under the Securities Act, of the resale of the shares of Common
Stock issuable upon exercise of the Warrants. The Company shall use its best efforts to cause the same to become effective and to maintain the effectiveness of such registration statement, and a current prospectus relating thereto, until the
expiration of the Warrants in accordance with the provisions of this Agreement. 
 7.4.2 Cashless Exercise at Company’s Option.
If the Common Stock is at the time of any exercise of a Warrant not listed on a national securities exchange such that it satisfies the definition of a “covered security” under Section 18(b)(1) of the Securities Act (or any successor
statute), the Company may, at its option, (i) require holders of Warrants who exercise Warrants to exercise such Warrants on a “cashless basis” in accordance with Section 3(a)(9) of the Securities Act (or any successor statute)
as described in subsection 3.3.1(b) and (ii) in the event the Company so elects, the Company shall (x) not be required to file or maintain in effect a registration statement for the registration, under the Securities Act, of the
Common Stock issuable upon exercise of the Warrants, notwithstanding anything in this Agreement to the contrary, and (y) use its best efforts to register or qualify the Common Stock issuable upon exercise of the Warrant under the blue sky laws
of the state of residence of the exercising Warrant holder to the extent an exemption is not available. 
 8. Concerning the Warrant Agent and Other
Matters. 
 8.1 Payment of Taxes. The Company shall from time to time promptly pay all taxes and charges that may be imposed upon
the Company or the Warrant Agent in respect of the issuance or delivery of shares of Common Stock upon the exercise of the Warrants, but the Company shall not be obligated to pay any transfer taxes in respect of the Warrants or such shares of Common
Stock.

 8.2 Resignation, Consolidation, or Merger of Warrant Agent. 

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

 -13- 

 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. 

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

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

 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 [•], [•]
2021 (the “Warrant Agreement”), duly executed and delivered by the Company to Continental Stock Transfer & Trust Company, a New York corporation, as warrant agent (the “ Warrant Agent”), which
Warrant Agreement is hereby incorporated by reference in and made a part of this instrument and is hereby referred to for a description of the rights, limitation of rights, obligations, duties and immunities thereunder of the Warrant Agent, the
Company and the holders (the words “holders” or “holder” meaning the Registered Holders or Registered Holder) 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. 

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.

Maker and shall remain unpaid under this Note on the Maturity Date (as defined below) in lawful money of the United States of America, on the terms and conditions described below. All payments on this Note shall be made by wire transfer of
immediately available funds or as otherwise determined by the Maker to such account as the Payee may from time to time designate by written notice in accordance with the provisions of this Note. 

1. Principal. The entire unpaid principal balance of this Note shall be payable on the earlier of: (i) June 30, 2021,
and (ii) the date on which Maker consummates an initial public offering of its securities (such earlier date, the “Maturity Date”). The principal balance may be prepaid at any time by Maker, at its election and without penalty.
Under no circumstances shall any individual, including but not limited to any officer, director, employee or shareholder of the Maker, be obligated personally for any obligations or liabilities of the Maker hereunder. 

2. Drawdown Requests. Maker and Payee agree that Maker may request, from time to time, up to Three Hundred Thousand Dollars
($300,000) in drawdowns under this Note to be used for costs and expenses related to Maker’s formation and the proposed initial public offering of its securities (the “IPO”). Principal of this Note may be drawn down from time

3. Interest. No interest shall accrue on the unpaid principal balance of this Note. 

4. Application of Payments. All payments shall be applied first to payment in full of any costs incurred in the collection of any
sum due under this Note, including (without limitation) reasonable attorney’s fees, then to the payment in full of any late charges and finally to the reduction of the unpaid principal balance of this Note. 

5. Events of Default. The following shall constitute an event of default (“Event of Default”):

official) of Maker or for any substantial part of its property, or the making by it of any assignment for the benefit of creditors, or the failure of Maker generally to pay its debts as such debts become due, or the taking of corporate action by
Maker in furtherance of any of the foregoing. 

 (c) Involuntary Bankruptcy, Etc. The entry of a decree or order for relief by a court
having jurisdiction in the premises in respect of Maker in an involuntary case under any applicable bankruptcy, insolvency or other similar law, or appointing a receiver, liquidator, assignee, custodian, trustee, sequestrator (or similar official)

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, on 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 of the payment of this Note, and agrees that its liability shall be unconditional, without regard to the liability of any other 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
