 Exhibit 4.4 

FORM OF WARRANT AGREEMENT 

between 
 SUPERNOVA
PARTNERS ACQUISITION COMPANY, INC. 
 and 

CONTINENTAL STOCK TRANSFER & TRUST COMPANY 

THIS WARRANT AGREEMENT (this “Agreement”), dated as
of                , 2020, is by and between Supernova Acquisition Partners Company, Inc., a Delaware corporation (the “Company”), and Continental Stock
Transfer & Trust Company, a New York corporation, as warrant agent (in such capacity, the “Warrant Agent”). 

WHEREAS, the Company has entered into that certain Private Placement Warrants Purchase Agreement with Supernova Partners LLC, a Delaware
limited liability company (the “Sponsor”), pursuant to which the Sponsor agreed to purchase an aggregate of 5,333,333 warrants (or 5,933,333 warrants in the aggregate if the Over-allotment Option (as defined below) in connection
with the Company’s Offering (as defined below) is exercised in full) simultaneously with the closing of the Offering (and the closing of the Over-allotment Option, if applicable) bearing the legend set forth in
Exhibit B hereto (the “Private Placement Warrants”) at a purchase price of $1.50 per Private Placement Warrant; and 

WHEREAS, on September 25, 2020 the Company entered into Forward Purchase Agreements (the “Forward Purchase Agreements”)
with certain purchasers, pursuant to which such purchasers will be issued warrants (the “Forward Purchase Warrants”) in a private placement transaction to occur at or prior to the time of the Company’s initial Business
Combination (as defined below); and 
 WHEREAS, in order to finance the Company’s transaction costs in connection with an intended
initial Business Combination, the Sponsor or an affiliate of the Sponsor or certain of the Company’s officers and directors may, but are not obligated to, loan the Company funds as the Company may require, of which up to $1,500,000 of such
loans may be convertible into up to an additional 1,000,000 Private Placement Warrants at a price of $1.50 per warrant (the “Working Capital Warrants”); and 

WHEREAS, the Company is engaged in an initial public offering (the “Offering”) of units of the Company’s equity
securities, each such unit comprised of one share of Common Stock (as defined below) and one-third of one Public Warrant (as defined below) (the “Units”) and, in connection therewith, has determined to issue and deliver 10,000,000
redeemable warrants (or up to 11,500,000 redeemable warrants to the extent the Over-allotment Option is exercised) to public investors in the Offering (the “Public Warrants” and, collectively with the Working Capital Warrants, the
Private Placement Warrants and the Forward Purchase Warrants, the “Warrants”). Each whole Warrant entitles the holder thereof to purchase one share of Class A common stock of the Company, par value $0.0001 per share
(“Common Stock”), for $11.50 per whole share, subject to adjustment as described herein. Only whole Warrants are exercisable. A holder of the Warrants will not be able to exercise any fraction of a Warrant; and 












 WHEREAS, the Company has filed with the Securities and Exchange Commission (the
“Commission”) a registration statement on Form S-1, File No. 333-249053 (the “Registration Statement”), and prospectus (the
“Prospectus”), for the registration, under the Securities Act of 1933, as amended (the “Securities Act”), of the Units and the Public Warrants and the shares of Common Stock included in the Units; and 

WHEREAS, the Company desires the Warrant Agent to act on behalf of the Company, and the Warrant Agent is willing to so act, in connection with
the issuance, registration, transfer, exchange, redemption and exercise of the Warrants; and 
 WHEREAS, the Company desires to provide for
the form and provisions of the Warrants, the terms upon which they shall be issued and exercised, and the respective rights, limitation of rights, and immunities of the Company, the Warrant Agent, and the holders of the Warrants; and 

WHEREAS, all acts and things have been done and performed which are necessary to make the Warrants, when executed on behalf of the Company and
countersigned by or on behalf of the Warrant Agent (if a physical certificate is issued), 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 initially 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 certificate 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. All of the Public Warrants shall initially be issued in book-entry form through the facilities of The Depository Trust Company (the
“Depositary”) and registered in the name of Cede & Co., a nominee of the Depositary. Ownership of beneficial interests in the Public Warrants shall be shown on, and the transfer of such ownership shall be effected through,
records maintained by institutions that have accounts with the Depositary (each such institution, with respect to a Warrant in its account, a “Participant”). 

  
 2 













 If the Depositary subsequently ceases to make its book-entry settlement system available for
the Public Warrants, the Company may instruct the Warrant Agent regarding making other arrangements for book-entry settlement. In the event that the Public Warrants are not eligible for, or it is no longer necessary to have the Public Warrants
available in, book-entry form, the Warrant Agent shall deliver to the Depositary (i) written instructions to deliver to the Warrant Agent for cancellation each book-entry Public Warrant and (ii) definitive certificates in physical form
evidencing such Warrants (“Definitive Warrant Certificates”), which shall be in the form annexed hereto as Exhibit A. 

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

2.3.2 Registered Holder. Prior to due presentment for registration of transfer of any Warrant, the Company and the Warrant Agent may
deem and treat the person in whose name such Warrant is registered in the Warrant Register (the “Registered Holder”) as the absolute owner of such Warrant and of each Warrant represented thereby (notwithstanding any notation of
ownership or other writing on any physical certificate made by anyone other than the Company or the Warrant Agent), for the purpose of any exercise thereof, and for all other purposes, and neither the Company nor the Warrant Agent shall be affected
by any notice to the contrary. 
 2.4 Detachability of Warrants. The shares of Common Stock and Public Warrants comprising the Units
shall begin separate trading on the 52nd day following the date of the Prospectus or, if such 52nd day is not on a day, other than a Saturday, Sunday or federal holiday, on which banks in New York City are generally open for normal business (a
“Business Day”), then on the immediately succeeding Business Day following such date, or earlier (the “Detachment Date”) with the consent of J.P. Morgan Securities LLC and Jefferies LLC, as representatives of the
several underwriters, but in no event shall the shares of Common Stock and the Public Warrants comprising the Units be separately traded until (A) the Company has filed a Current Report on Form 8-K with
the Commission containing an audited balance sheet reflecting the receipt by the Company of the gross proceeds of the Offering, including the proceeds then received by the Company from the exercise by the underwriters of their right to purchase
additional Units in the Offering (the “Over-allotment Option”), if the Over-allotment Option is exercised prior to the filing of the Form 8-K, and (B) the Company issues a press release
and files with the Commission a Current Report on Form 8-K announcing when such separate trading shall begin. 

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

  
 3 













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

(b) in the case of an individual, by gift to a member of the individual’s immediate family or to a trust, the beneficiary of which is a
member of the individual’s immediate family or an affiliate of such person, or to a charitable organization; 
 (c) in the case of an
individual, by virtue of laws of descent and distribution upon death of the individual; 
 (d) in the case of an individual, pursuant to a
qualified domestic relations order; 
 (e) by private sales or transfers made in connection with the consummation of the Company’s
initial Business Combination at prices no greater than the price at which the applicable Warrants were originally purchased; 
 (f) in the
event of the Company’s liquidation prior to the completion of its initial Business Combination; 
 (g) by virtue of the laws of the
State of Delaware or the Sponsor’s limited liability company agreement, as amended, upon dissolution of the Sponsor; or 
 (h) in the
event of the Company’s completion of a liquidation, merger, stock exchange, reorganization or other similar transaction which results in all of the Company’s stockholders having the right to exchange their shares of Common Stock for cash,
securities or other property subsequent to the completion of the Company’s initial Business Combination; 
 provided, however, that in
the case of clauses (a) through (g), these permitted transferees (the “Permitted Transferees”) must enter into a written agreement agreeing to be bound by these transfer restrictions and the other restrictions contained in the
letter agreement (defined in the Prospectus) between Company and its initial stockholders.

 2.7 Working Capital Warrants. Each of the Working Capital Warrants shall be identical
to the Private Placement Warrants. Except as expressly provided herein or the context otherwise requires, the Working Capital Warrants shall be treated as Private Placement warrants under this Agreement. 

2.8 Forward Purchase Warrants. Each of the Forward Purchase Warrants shall be identical to the Public Warrants. Except as expressly
provided herein or the context otherwise requires, the Forward Purchase Warrants shall be treated as Public Warrants under this Agreement. 
 3. Terms and
Exercise of Warrants. 
 3.1 Warrant Price. Each Warrant shall, when countersigned by the Warrant Agent (if a physical certificate
is issued), entitle the Registered Holder thereof, subject to the provisions of such Warrant and of this Agreement, to purchase from the Company the number of shares of Common Stock stated therein, at the price of $11.50 per share, subject to the
adjustments provided in Section 4 hereof and in the last sentence of this Section 3.1. The term “Warrant Price” as used in this Agreement shall mean the price per share (including
in cash or by payment of Warrants pursuant to a “cashless exercise,” to the extent permitted hereunder) described in the prior sentence at which shares of Common Stock may be purchased at the time a Warrant is exercised. The Company in its
sole discretion may lower the Warrant Price at any time prior to the Expiration Date (as defined below) for a period of not less than twenty (20) Business Days, provided, that the Company shall provide at least twenty (20) days
prior written notice of such reduction to Registered Holders of the Warrants and, provided further that any such reduction shall be identical among all of the Warrants. 

3.2 Duration of Warrants. A Warrant may be exercised only during the period (the “Exercise Period”) commencing on the
later of: (i) the date that is thirty (30) days after the first date on which the Company completes a merger, capital stock exchange, asset acquisition, stock purchase, reorganization or similar business combination, involving the Company
and one or more businesses (a “Business Combination”) and (ii) the date that is twelve (12) months from the date of the closing of the Offering, and terminating at the earliest to occur of: (x) 5:00 p.m., New York City
time on the date that is five (5) years after the date on which the Company completes its initial Business Combination, (y) the liquidation of the Company, if the Company fails to complete a Business Combination, and (z) other than
with respect to the Private Placement Warrants and Working Capital Warrants then held by the Sponsor or any of its Permitted Transferees, with respect to a redemption pursuant to Section 6.1 hereof, at 5:00 p.m., New York
City time on the Redemption Date (as defined below) as provided in Section 6.3 hereof (the “Expiration Date”); provided, however, that the exercise of any Warrant shall be subject to the
satisfaction of any applicable conditions, as set forth in subsection 3.3.2 below with respect to an effective registration statement or a valid exemption therefrom being available. Except with respect to the right to
receive the Redemption Price (as defined below) (other than with respect to a Private Placement Warrant or a Working Capital Warrant held by the Sponsor or any of its Permitted Transferees in connection with a redemption pursuant to
Section 6.1 

  
 5 













 
hereof) in the event of a redemption (as set forth in Section 6 hereof), each Warrant (other than a Private Placement Warrant or a Working Capital Warrant held by the
Sponsor or its Permitted Transferees, in the event of a redemption pursuant to Section 6.1 hereof) 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 Warrants by delaying the Expiration Date; provided that the Company
shall provide at least twenty (20) days prior written notice of any such extension to Registered Holders of the Warrants and, provided further that any such extension shall be identical in duration among all the Warrants. 

3.3 Exercise of Warrants. 

3.3.1 Payment. Subject to the provisions of the Warrant and this Agreement, a Warrant may be exercised by the Registered Holder thereof
by delivering to the Warrant Agent at its Compliance Department (i) the Definitive Warrant Certificate evidencing the Warrants to be exercised, or, in the case of a Warrant represented by a book-entry, the Warrants to be exercised (the
“Book-Entry Warrants”) on the records of the Depositary to an account of the Warrant Agent at the Depositary designated for such purposes in writing by the Warrant Agent to the Depositary from time to time, (ii) an election to
purchase (“Election to Purchase”) any shares of Common Stock pursuant to the exercise of a Warrant, properly completed and executed by the Registered Holder on the reverse of the Definitive Warrant Certificate or, in the case of a
Book-Entry Warrant, properly delivered by the Participant in accordance with the Depositary’s procedures, and (iii) payment in full of 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 wire payable to the order of the Warrant Agent; 

(b) in the event of a redemption pursuant to Section 6.1 hereof in which the Company’s board of directors (the
“Board”) has elected to require all holders of the Warrants to exercise such Warrants on a “cashless basis,” by surrendering the Warrants for that number of shares of Common Stock equal to the lesser of (A) 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 and (B) 0.361 shares of Common Stock. Solely for purposes of this subsection 3.3.1(b), Section 6.2 and Section 6.4, the
“Fair Market Value” shall mean the volume-weighted average price of the shares of Common Stock for the ten (10) trading days ending on the third trading day prior to the date on which the notice of redemption is sent to the holders of
the Warrants, pursuant to Section 6 hereof; 
 (c) with respect to any Private Placement Warrant or Working
Capital Warrant, so long as such Private Placement Warrant or Working Capital Warrant is held by the Sponsor or a Permitted Transferee, by surrendering the Warrants for that number of shares of Common Stock equal to the lesser of (A) 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 

  
 6 













 
“Fair Market Value,” as defined in this subsection 3.3.1(c), over the Warrant Price by (y) the Fair Market Value and (B) 0.361 shares of Common Stock.
Solely for purposes of this subsection 3.3.1(c), the “Fair Market Value” shall mean the volume-weighted average price of the shares of Common Stock for the ten (10) trading days ending on the third trading
day prior to the date on which notice of exercise of the Private Placement Warrant or Working Capital Warrant, as the case may be, is sent to the Warrant Agent; 

(d) as provided in Section 6.2 with respect to a Make-Whole Exercise; or 

(e) as provided in Section 7.4 hereof. 

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

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

  
 7 













 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 such 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 (A) 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,
(B) a more recent public announcement by the Company or (C) any other notice by the Company or the Company’s transfer agent setting forth the number of shares of Common Stock outstanding. For any reason at any time, upon the written
request of the holder of the Warrant, the Company shall, within two (2) Business Days, confirm orally and in writing to such holder the number of shares of Common Stock then outstanding. In any case, the number of outstanding shares of Common
Stock shall be determined after giving effect to the conversion or exercise of equity securities of the Company by the holder and its affiliates since the date as of which such number of outstanding shares of Common Stock was reported. By written
notice to the Company, the holder of a Warrant may from time to time increase or decrease the Maximum Percentage applicable to such holder to any other percentage specified in such notice; provided, however, that any such increase
shall not be effective until the sixty-first (61st) day after such notice is delivered to the Company.

 4. Adjustments. 

4.1 Stock Dividends. 

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

4.1.2 Extraordinary Dividends. If the Company, at any time while the Warrants are outstanding and unexpired, shall pay a dividend or
make a distribution in cash, securities or other assets to the holders of the Common Stock on account of such shares of Common Stock (or other shares of the Company’s capital stock into which the Warrants are convertible), other than
(A) as described in subsection 4.1.1 above, (B) Ordinary Cash Dividends (as defined below), (C) to satisfy the redemption rights of the holders of the Common Stock in connection with a proposed initial Business
Combination, (D) to satisfy the redemption rights of the holders of Common Stock in connection with a stockholder vote to amend the Company’s amended and restated certificate of incorporation to modify the substance or timing of the
Company’s obligation to allow redemption in connection with the Company’s initial Business Combination or to redeem 100% of Common Stock if the Company does not complete the Business Combination within 24 months from the closing of the
Offering or any extended time that the Company has to consummate a Business Combination beyond 24 months as a result of a stockholder vote to amend the Company’s amended and restated certificate of incorporation or with respect to any other
provision relating to the rights of holders of Common Stock or pre-initial Business Combination activity, or (E) in connection with the redemption of all of the Company’s public shares upon the
failure of the Company to complete its initial Business Combination and any subsequent distribution of its assets upon its liquidation (any such non-excluded event being referred to herein as an
“Extraordinary Dividend”), then the Warrant Price shall be decreased, effective immediately after the effective date of such Extraordinary Dividend, by the amount of cash and/or the fair market value (as determined by the Board, in
good faith) of any securities or other assets paid on each share of Common Stock in respect of such Extraordinary Dividend. For purposes of this subsection 4.1.2, “Ordinary Cash Dividends” means any cash
dividend or cash distribution which, when combined on a per share basis, with the per share amounts of all other cash dividends and cash distributions paid on the Common Stock during the 365-day period ending
on the date of declaration of such dividend or distribution (as adjusted to appropriately reflect any of the events referred to in other subsections of this Section 4 and excluding cash dividends or cash distributions
that resulted in an adjustment to the Warrant Price or to the number of shares of Common Stock issuable on exercise of each Warrant) to the extent it does not exceed $0.50. 

  
 9 













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

4.3.1 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. 
 4.3.2 If (i) the Company issues additional shares of Common Stock or securities convertible into or
exercisable or exchangeable for shares of Common Stock for capital raising purposes in connection with the closing of its initial Business Combination (other than securities issued pursuant to the Forward Purchase Agreements) at an issue price or
effective issue price of less than $9.20 per share of Common Stock, with such issue price or effective issue price to be determined in good faith by the Board (and in the case of any such issuance to the Sponsor or its affiliates, without taking
into account any founder shares held by the Sponsor or such affiliates, as applicable, prior to such issuance) (the “New Issuance Price”), (ii) aggregate gross proceeds from such issuances represent more than 60% of the total equity
proceeds, and interest thereon, available for the funding of the initial Business Combination on the date of the consummation of the initial Business Combination (net of redemptions), and (iii) the volume-weighted average trading price of the
Common Stock during the 10-trading day period starting on the trading day after the closing of the initial Business Combination (such price, the “Market Value”) is below $9.20 per share, then
the Warrant Price shall be adjusted (to the nearest cent) to be equal to 115% of the higher of the Market Value and the New Issuance Price, and the $10.00 and $18.00 per share redemption trigger prices described in Section 6.2 and
Section 6.1, respectively, will be adjusted (to the nearest cent) to 100% and 180%, respectively, of the higher of the Market Value and the New Issuance Price. 

4.4 Replacement of Securities upon Reorganization, etc. In case of any reclassification or reorganization of the outstanding shares of
Common Stock (other than a change under subsections 4.1.1 or 4.1.2 or Section 4.2 hereof or that solely affects the par value of such shares of Common Stock), or in the case of any merger or consolidation
of the Company with or into another corporation (other than a consolidation or merger in which the Company is the continuing corporation and that does not result in any reclassification or reorganization of the outstanding shares of Common Stock),
or in the case of any sale or conveyance to another 

  
 10 













 
corporation or entity of the assets or other property of the Company as an entirety or substantially as an entirety in connection with which the Company is dissolved, the holders of the Warrants
shall thereafter have the right to purchase and receive, upon the basis and upon the terms and conditions specified in the Warrants and in lieu of the shares of Common Stock of the Company immediately theretofore purchasable and receivable upon the
exercise of the rights represented thereby, the kind and amount of shares of stock or other securities or property (including cash) receivable upon such reclassification, reorganization, merger or consolidation, or upon a dissolution following any
such sale or transfer, that the holder of the Warrants would have received if such holder had exercised his, her or its Warrant(s) immediately prior to such event (the “Alternative Issuance” ); provided, however, that
(i) if the holders of the Common Stock were entitled to exercise a right of election as to the kind or amount of securities, cash or other assets receivable upon such consolidation or merger, then the kind and amount of securities, cash or
other assets constituting the Alternative Issuance for which each Warrant shall become exercisable shall be deemed to be the weighted average of the kind and amount received per share by the holders of the Common Stock in such consolidation or
merger that affirmatively make such election, and (ii) if a tender, exchange or redemption offer shall have been made to and accepted by the holders of the Common Stock (other than a tender, exchange or redemption offer made by the Company in
connection with redemption rights held by stockholders of the Company as provided for in the Company’s amended and restated certificate of incorporation or as a result of the repurchase of shares of Common Stock by the Company if a proposed
initial Business Combination is presented to the stockholders of the Company for approval) under circumstances in which, upon completion of such tender or exchange offer, the maker thereof, together with members of any group (within the meaning of
Rule 13d-5(b)(1) under the Exchange Act (or any successor rule)) of which such maker is a part, and together with any affiliate or associate of such maker (within the meaning of Rule 12b-2 under the Exchange Act (or any successor rule)) and any members of any such group of which any such affiliate or associate is a part, own beneficially (within the meaning of Rule
13d-3 under the Exchange Act (or any successor rule)) more than 50% of the outstanding shares of Common Stock, the holder of a Warrant shall be entitled to receive as the Alternative Issuance, the highest
amount of cash, securities or other property to which such holder would actually have been entitled as a stockholder if such Warrant holder had exercised the Warrant prior to the expiration of such tender or exchange offer, accepted such offer and
all of the Common Stock held by such holder had been purchased pursuant to such tender or exchange offer, subject to adjustments (from and after the consummation of such tender or exchange offer) as nearly equivalent as possible to the adjustments
provided for in this Section 4; provided, further, that if less than 70% of the consideration receivable by the holders of Common Stock in the applicable event is payable in the form of common equity in the
successor entity that is listed for trading on a national securities exchange or is quoted in an established over-the-counter market, or is to be so listed for trading
or quoted immediately following such event, and if the Registered Holder properly exercises the Warrant within thirty (30) days following the public disclosure of the consummation of such applicable event by the Company pursuant to a Current
Report on Form 8-K filed with the Commission, the Warrant Price shall be reduced by an amount (in dollars) equal to the difference of (i) the Warrant Price in effect prior to such reduction minus
(ii) (A) the Per Share Consideration (as defined below) (but in no event less than zero) minus (B) the Black-Scholes Warrant Value (as defined below). The “Black-Scholes Warrant Value” means the value of a Warrant
immediately prior to the consummation of the applicable event based on the 

  
 11 













 
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 shares of 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 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 shares of 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. 

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. 

  
 12 













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

4.9 No Adjustment. For the avoidance of doubt, no adjustment shall be made to the terms of the Warrants solely as a result of an
adjustment to the conversion ratio of the Class B common stock of the Company (the “Class B Common Stock”) into Common Stock or the conversion of the Class B Common Stock into Common Stock, in each case,
pursuant to the Company’s amended and restated certificate of incorporation, as amended from time to time. 
 5. Transfer and Exchange of
Warrants. 
 5.1 Registration of Transfer. The Warrant Agent shall register the transfer, from time to time, of any outstanding
Warrant upon the Warrant Register, upon surrender of such Warrant for transfer, in the case of certificated Warrants, properly endorsed with signatures properly guaranteed and accompanied by appropriate instructions for transfer. Upon any such
transfer, a new Warrant representing an equal aggregate number of Warrants shall be issued and the old Warrant shall be cancelled by the Warrant Agent. The Warrants so cancelled shall be delivered by the Warrant Agent to the Company from time to
time upon request. 
 5.2 Procedure for Surrender of Warrants. Warrants may be surrendered to the Warrant Agent, together with a
written request for exchange or transfer, and thereupon the Warrant Agent shall issue in exchange therefor one or more new Warrants as requested by the Registered Holder of the Warrants so surrendered, representing an equal aggregate number of
Warrants; provided, however, that in the event that a Warrant surrendered for transfer bears a restrictive legend (as in the case of the Private Placement Warrants and Working Capital Warrants), the Warrant Agent shall not cancel such
Warrant and issue new Warrants in exchange thereof until the Warrant Agent has received an opinion of counsel for the Company stating that such transfer may be made and indicating whether the new Warrants must also bear a restrictive legend. 

5.3 Fractional Warrants. The Warrant Agent shall not be required to effect any registration of transfer or exchange of Warrants which
would result in the issuance of a warrant certificate or book-entry position for a fraction of a warrant, except as part of the Units. 
 5.4
Service Charges. No service charge shall be made for any exchange or registration of transfer of Warrants. 
 5.5 Warrant Execution
and Countersignature. The Warrant Agent is hereby authorized to countersign and to deliver, in accordance with the terms of this Agreement, the Warrants required to be issued pursuant to the provisions of this
Section 5, and the Company, whenever required by the Warrant Agent, shall supply the Warrant Agent with Warrants duly executed on behalf of the Company for such purpose. 

  
 13 













 5.6 Transfer of Warrants. Prior to the Detachment Date, the Public Warrants may be
transferred or exchanged only together with the Unit in which such Warrant is included, and only for the purpose of effecting, or in conjunction with, a transfer or exchange of such Unit. Furthermore, each transfer of a Unit on the register relating
to such Units shall operate also to transfer the Warrants included in such Unit. Notwithstanding the foregoing, the provisions of this Section 5.6 shall have no effect on any transfer of Warrants on and after the Detachment
Date. 
 6. Redemption. 
 6.1
Redemption of Warrants When the Price per Share of Class A Common Stock Equals or Exceeds $18.00. Subject to Section 6.5 hereof, not less than all of the outstanding Warrants may be redeemed, at
the option of the Company, at any time while they are exercisable and prior to their expiration, at the office of the Warrant Agent, upon notice to the Registered Holders of the Warrants, as described in Section 6.3 below,
at the price (the “Redemption Price”) of $0.01 per Warrant, provided that the last reported sales price of the Common Stock reported has been at least $18.00 per share (subject to adjustment in compliance with
Section 4 hereof), on each of twenty (20) trading days within the thirty (30) trading-day period ending on the third trading day prior to the date on which notice of the
redemption is given and provided that there is an effective registration statement covering the shares of Common Stock issuable upon exercise of the Warrants, and a current prospectus relating thereto, available throughout the 30-day Redemption Period (as defined in Section 6.3 below) or the Company has elected to require the exercise of the Warrants on a “cashless basis” pursuant to
subsection 3.3.1. 
 6.2 Redemption of Warrants When the Price per Share of Class A Common
Stock Equals or Exceeds $10.00. Subject to Section 6.5 hereof, not less than all of the outstanding Warrants may be redeemed, at the option of the Company, 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 reported sales price of
the Common Stock reported has been at least $10.00 per share (subject to adjustment in compliance with Section 4 hereof), on the trading day prior to the date on which notice of the redemption is given, the Private
Placement Warrants are also concurrently called for redemption on the same terms as the outstanding Public Warrants and there is an effective registration statement covering the 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). During the 30-day Redemption
Period 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 below, based on the Redemption Date (calculated for purposes of the table as the period to expiration of the Warrants) and
the “Fair Market Value” (as such term is defined in subsection 3.3.1(b)) (a “Make-Whole Exercise”).

 The exact Fair Market Value and the Redemption Date may not be set forth in the table above, in which case, if
the Fair Market Value is 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 will be determined by
a straight-line interpolation between the number of shares set forth for the higher and lower Fair Market Values and the earlier and later redemption dates, as applicable, based on a 365 or 366-day year, as
applicable. 
 The stock prices set forth in the column headings of the table above shall be adjusted as of any date on which the number of
shares issuable upon exercise of a Warrant is adjusted pursuant to Section 4.1 or Section 4.2. In such an event, the number of shares in the table above shall be adjusted by multiplying such share
amounts by a fraction, the numerator of which is the number of shares deliverable upon exercise of a Warrant immediately prior to such adjustment and the denominator of which is the number of shares deliverable upon exercise of a Warrant as so
adjusted. The number of shares in the table above shall be adjusted in the same manner and at the same time as the number of shares issuable upon exercise of a Warrant. If the Warrant Price is adjusted (i) pursuant to Section 4.3.2, the
adjusted share prices set forth in the column headings of the table above shall be multiplied by a fraction, the numerator of which is the higher of the Market Value and the New Issuance Price and the denominator of which is $10.00 and (ii) in
the case of an adjustment pursuant to Section 4.1.2, the adjusted share prices set forth in the column headings of the table above shall equal the unadjusted share price less the decrease in the Warrant Price of a Warrant
pursuant to such exercise price adjustment. In no event will the number of shares issued in connection with a Make-Whole Exercise exceed 0.361 shares of Common Stock per Warrant (subject to adjustment). 

  
 15 













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

6.4 Exercise After Notice of Redemption. The Warrants may be exercised for cash (or, if in connection with a redemption pursuant to
Section 6.2 of this Agreement, on a “cashless basis” in accordance with such Section 6.2 of this Agreement) at any time after notice of redemption shall have been given by the Company pursuant to
Section 6.3 hereof and prior to the Redemption Date. In the event that the Company determines to require all holders of Warrants to exercise their Warrants on a “cashless basis” pursuant to
subsection 3.3.1, the notice of redemption shall contain the information necessary to calculate the number of shares of Common Stock to be received upon exercise of the Warrants, including the “Fair Market Value”
(as such term is defined in subsection 3.3.1(b) hereof) in such case. On and after the Redemption Date the record holder of the Warrants shall have no further rights except to receive, upon surrender of the Warrants, the
Redemption Price. 
 6.5 Exclusion of Private Placement Warrants. 

6.5.1 The Company agrees that the redemption rights provided in Section 6.1 hereof shall apply to neither the Private
Placement Warrants nor the Working Capital Warrants if at the time of the redemption such Private Placement Warrants or Working Capital Warrants continue to be held by the Sponsor or its Permitted Transferees. However, once such Private Placement
Warrants or Working Capital Warrants are transferred (other than to Permitted Transferees in accordance with Section 2.6), the Company may redeem such Private Placement Warrants or Working Capital Warrants pursuant to
Section 6.1 hereof, provided that the criteria for redemption are met, including the opportunity of the holder of such Private Placement Warrants or Working Capital Warrants to exercise such Private Placement Warrants or
Working Capital Warrants prior to redemption pursuant to Section 6.4. Private Placement Warrants and Working Capital Warrants that are transferred to persons other than Permitted Transferees shall upon such transfer cease
to be Private Placement Warrant or Working Capital Warrants, respectively, and shall become Public Warrants under this Agreement. 
 6.5.2
The Company agrees that the provisions of Section 6.2 shall apply to the Private Placement Warrants and the Working Capital Warrants parri passu with the Public Warrants. The Company agrees that the provisions
of Section 6.1 and Section 6.2 shall apply to the Forward Purchase Warrants parri passu with the Public Warrants. 

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

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

  
 16 













 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 twenty
(20) Business Days after the closing of its initial Business Combination, it shall use its commercially reasonable efforts to file with the Commission a registration statement under the Securities Act covering the issuance of the shares of
Common Stock issuable upon exercise of the Warrants. The Company shall use its commercially reasonable 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 redemption or expiration of the Warrants in accordance with the provisions of this Agreement. If any such registration statement has not been declared effective by the 60th Business Day following the closing of the Business
Combination, holders of the Warrants shall have the right, during the period beginning on the 61st Business Day after the closing of the Business Combination and ending upon such registration statement being declared effective by the Commission, and
during any other period when the Company shall fail to have maintained an effective registration statement covering the shares of Common Stock issuable upon exercise of the Warrants, to exercise such Warrants on a “cashless basis,” by
exchanging the Warrants (in accordance with Section 3(a)(9) of the Securities Act (or any successor rule) or another exemption) for that number of shares of Common Stock equal to the lesser of (A) 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 below) over the Warrant Price by (y) the Fair Market Value and (B) 0.361 shares of
Common Stock. Solely for purposes of this subsection 7.4.1, “Fair Market Value” shall mean the volume weighted average price of the Common Stock as reported during the ten (10) trading day period ending on
the trading day prior to the date that notice of exercise is received by the Warrant Agent from the holder of such Warrants or its securities broker or intermediary. The date that notice of cashless exercise is received by the Warrant Agent shall be
conclusively determined by the Warrant Agent. In connection with the “cashless exercise” of a Public Warrant, the Company shall, upon request, provide the Warrant Agent with an opinion of counsel for the Company (which shall be an outside
law firm with securities law experience) stating that (i) the exercise of the Warrants on a cashless basis in accordance with this subsection 7.4.1 is not required to be registered under the


  
 17 













 
Securities Act and (ii) the shares of Common Stock issued upon such exercise shall be freely tradable under United States federal securities laws by anyone who is not an affiliate (as such
term is defined in Rule 144 under the Securities Act (or any successor rule)) of the Company and, accordingly, shall not be required to bear a restrictive legend. Except as provided in subsection 7.4.2, for the avoidance of
any doubt, unless and until all of the Warrants have been exercised or redeemed, the Company shall continue to be obligated to comply with its registration obligations under the first three sentences of this
subsection 7.4.1. 
 7.4.2 Cashless Exercise at Company’s Option. If the Common Stock is at the time of
any exercise of a Warrant not listed on a national securities exchange such that it satisfies the definition of a “covered security” under Section 18(b)(1) of the Securities Act (or any successor rule), the Company may, at its option,
(i) require holders of Public Warrants who exercise Public Warrants to exercise such Public Warrants on a “cashless basis” in accordance with Section 3(a)(9) of the Securities Act (or any successor rule) as described in
subsection 7.4.1 and (ii) in the event the Company so elects, the Company shall (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 commercially reasonable efforts to register or qualify the Common Stock issuable upon exercise of the Public
Warrant under the blue sky laws of the state of residence of the exercising Public Warrant holder to the extent an exemption is not available. 
 8.
Concerning the Warrant Agent and Other Matters. 
 8.1 Payment of Taxes. The Company shall from time to time promptly pay all
taxes and charges that may be imposed upon the Company or the Warrant Agent in respect of the issuance or delivery of shares of Common Stock upon the exercise of the Warrants, but the Company shall not be obligated to pay any transfer taxes in
respect of the Warrants or such shares of Common Stock. 
 8.2 Resignation, Consolidation, or Merger of Warrant Agent. 

8.2.1 Appointment of Successor Warrant Agent. The Warrant Agent, or any successor to it hereafter appointed, may resign its duties and
be discharged from all further duties and liabilities hereunder after giving sixty (60) days’ notice in writing to the Company. If the office of the Warrant Agent becomes vacant by resignation or incapacity to act or otherwise, the Company
shall appoint in writing a successor Warrant Agent in place of the Warrant Agent. If the Company shall fail to make such appointment within a period of thirty (30) days after it has been notified in writing of such resignation or incapacity by
the Warrant Agent or by the holder of a Warrant (who shall, with such notice, submit his 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 

  
 18 













 
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 Common Stock not later than the effective
date of any such appointment. 
 8.2.3 Merger or Consolidation of Warrant Agent. Any corporation into which the Warrant Agent may be
merged or with which it may be consolidated or any corporation resulting from any merger or consolidation to which the Warrant Agent shall be a party shall be the successor Warrant Agent under this Agreement without any further act. 

8.3 Fees and Expenses of Warrant Agent. 

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

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

8.4 Liability of Warrant Agent. 

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

  
 19 













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

8.5 Acceptance of Agency. The Warrant Agent hereby accepts the agency established by this Agreement and agrees to perform the same upon
the terms and conditions herein set forth and among other things, shall account promptly to the Company with respect to Warrants exercised and concurrently account for, and pay to the Company, all monies received by the Warrant Agent for the
purchase of shares of Common Stock through the exercise of the Warrants. 
 8.6 Waiver. The Warrant Agent has no right of set-off or any other right, title, interest or claim of any kind (“Claim”) in, or to any distribution of, the Trust Account (as defined in that certain Investment Management Trust Agreement, dated
as of the date hereof, by and between the Company and Continental Stock Transfer & Trust Company, 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.

 THIS WARRANT

IN THE WARRANT AGREEMENT DESCRIBED BELOW 

SUPERNOVA PARTNERS ACQUISITION COMPANY, INC. 

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 “Warrants” and each, a “Warrant”) to purchase shares of Class A common stock, $0.0001 par value per share (“Common Stock”), of Supernova Partners Acquisition
Company, Inc., a Delaware corporation (the “Company”). Each Warrant entitles the holder, upon exercise during the period set forth in the Warrant Agreement referred to below, to receive from the Company that number of fully paid and
non-assessable shares of Common Stock as set forth below, at the exercise price (the “Exercise Price”) as determined pursuant to the Warrant Agreement, payable in lawful money (or through
“cashless exercise” as provided for in the Warrant Agreement) of the United States of America upon surrender of this Warrant Certificate and payment of the Exercise Price at the office or agency of the Warrant Agent referred to
below, subject to the conditions set forth herein and in the Warrant Agreement. Defined terms used in this Warrant Certificate but not defined herein shall have the meanings given to them in the Warrant Agreement. 

Each whole Warrant is initially exercisable for one fully paid and non-assessable share of Common
Stock. The number of shares of Common Stock issuable upon exercise of the Warrants is subject to adjustment upon the occurrence of certain events set forth in the Warrant Agreement. 

The initial Exercise Price per share of Common Stock for any Warrant is equal to $11.50 per share. If, upon the exercise of 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 the number of shares of Common Stock to be issued to the Warrant holder. The Exercise Price is
subject to adjustment upon the occurrence of certain events set forth in the Warrant Agreement. 

  
 A-1 













 Subject to the conditions set forth in the Warrant Agreement, the Warrants may be exercised
only during the Exercise Period and to the extent not exercised by the end of such Exercise Period, such Warrants shall become null and void. The 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, without regard to conflicts of laws principles thereof.

 Form of Warrant Certificate 

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

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

Notwithstanding anything else in this Warrant Certificate or the Warrant Agreement, no Warrant may be exercised unless at the time of exercise
(i) a registration statement covering the shares of Common Stock to be issued upon exercise is effective under the Securities Act and (ii) a prospectus thereunder relating to the shares of Common Stock is current, except through
“cashless exercise” as provided for in the Warrant Agreement. 
 The Warrant Agreement provides that upon the occurrence of
certain events the number of shares of Common Stock issuable upon exercise of the Warrants set forth on the face hereof may, subject to certain conditions, be adjusted. If, upon exercise of a Warrant, the holder thereof would be entitled to receive
a fractional interest in a share of Common Stock, the Company shall, upon exercise, round down to the nearest whole number of shares of Common Stock to be issued to the holder of the Warrant. 

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

  
 A-3 













 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.

is                        and that such shares of Common Stock be delivered to whose address is. If said number of shares of

In the event that the Warrant has been called for redemption by the Company pursuant to Section 6.2 of the Warrant
Agreement and a holder thereof elects to exercise its Warrant pursuant to a Make-Whole Exercise, the number of shares of Common Stock that this Warrant is exercisable for shall be determined in accordance with Section 6.2
of the Warrant Agreement. 
 In the event that the Warrant is a Private Placement Warrant that is to be exercised on a “cashless”
basis pursuant to subsection 3.3.1(c) of the Warrant Agreement, the number of shares of Common Stock that this Warrant is exercisable for shall be determined in accordance with subsection 3.3.1(c)
of the Warrant Agreement. 
 In the event that the Warrant is to be exercised on a “cashless” basis pursuant to
Section 7.4 of the Warrant Agreement, the number of shares of Common Stock that this Warrant is exercisable for shall be determined in accordance with Section 7.4 of the Warrant Agreement. 

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