RE: Securities Subscription Agreement 

Ladies and Gentlemen: 
 This agreement (the
“Agreement”) is entered into on September 9, 2020 by and between Supernova Partners LLC, a Delaware limited liability company (the “Subscriber” or “you”), and Supernova Partners Acquisition
Company, Inc., a Delaware corporation (the “Company”, “we” or “us”). Pursuant to the terms hereof, the Company hereby accepts the offer the Subscriber has made to purchase 11,500,000 shares of
Class B common stock, $0.0001 par value per share (the “Shares”), up to 1,500,000 of which are subject to forfeiture by you if the underwriters of the initial public offering (“IPO”) of units
(“Units”) of the Company, do not fully exercise their over-allotment option (the “Over-allotment Option”). The Company’s and the Subscriber’s agreements regarding such Shares are as follows: 

ARTICLE I. 
 PURCHASE OF SECURITIES

 Section 1.01 Purchase of Shares. For the sum of $25,000 (the “Purchase Price”), which the Company
acknowledges receiving in the form of a capital contribution, the Company hereby issues the Shares to the Subscriber, and the Subscriber hereby purchases the Shares from the Company, subject to forfeiture, on the terms and subject to the conditions
set forth in this Agreement. Concurrently with the Subscriber’s execution of this Agreement, the Company shall, at its option, deliver to the Subscriber a certificate registered in the Subscriber’s name representing the shares (the
“Original Certificate”), or effect such delivery in book-entry form. 
 ARTICLE II. 

REPRESENTATIONS, WARRANTIES AND AGREEMENTS 

Section 2.01 Subscriber’s Representations, Warranties and Agreements. To induce the Company to issue the Shares to the
Subscriber, the Subscriber hereby represents and warrants to the Company and agrees with the Company as follows: 
 (a) No Government
Recommendation or Approval. The Subscriber understands that no federal or state agency has passed upon or made any recommendation or endorsement of the offering of the Shares. 

 (b) No Conflicts. The execution, delivery and performance of this Agreement and the
consummation by the Subscriber of the transactions contemplated hereby do not violate, conflict with or constitute a default under (i) the formation and governing documents of the Subscriber, (ii) any agreement, indenture or instrument to
which the Subscriber is a party or (iii) any law, statute, rule or regulation to which the Subscriber is subject, or any agreement, order, judgment or decree to which the Subscriber is subject. 

(c) Organization and Authority. The Subscriber is a Delaware limited liability company, validly existing and in good standing under the
laws of Delaware and possesses all requisite power and authority necessary to carry out the transactions contemplated by this Agreement. Upon execution and delivery by you, this Agreement is a legal, valid and binding agreement of Subscriber,
enforceable against Subscriber in accordance with its terms, except as such enforceability may be limited by applicable bankruptcy, insolvency, fraudulent conveyance or similar laws affecting the enforcement of creditors’ rights generally and
subject to general principles of equity (regardless of whether enforcement is sought in a proceeding at law or in equity). 
 (d)
Experience, Financial Capability and Suitability. Subscriber is: (i) sophisticated in financial matters and is able to evaluate the risks and benefits of the investment in the Shares and (ii) able to bear the economic risk of its
investment in the Shares for an indefinite period of time because the Shares have not been registered under the Securities Act (as defined below) and therefore cannot be sold unless subsequently registered under the Securities Act or an exemption
from such registration is available. Subscriber is capable of evaluating the merits and risks of its investment in the Company and has the capacity to protect its own interests. Subscriber must bear the economic risk of this investment until the
Shares are sold pursuant to: (i) an effective registration statement under the Securities Act or (ii) an exemption from registration available with respect to such sale. Subscriber is able to bear the economic risks of an investment in the
Shares and to afford a complete loss of Subscriber’s investment in the Shares. 
 (e) Access to Information; Independent
Investigation. Prior to the execution of this Agreement, the Subscriber has had the opportunity to ask questions of and receive answers from representatives of the Company concerning an investment in the Company, as well as the finances,
operations, business and prospects of the Company, and the opportunity to obtain additional information to verify the accuracy of all information so obtained. In determining whether to make this investment, Subscriber has relied solely on
Subscriber’s own knowledge and understanding of the Company and its business based upon Subscriber’s own due diligence investigation and the information furnished pursuant to this paragraph. Subscriber understands that no person has been
authorized to give any information or to make any representations which were not furnished pursuant to this Article II and Subscriber has not relied on any other representations or information in making its investment
decision, whether written or oral, relating to the Company, its operations and/or its prospects. 
 (f) Regulation D Offering.
Subscriber represents that it is an “accredited investor” as such term is defined in Rule 501(a) of Regulation D under the Securities Act of 1933, as amended (the “Securities Act”), and acknowledges the sale
contemplated hereby is being made in reliance on a private placement exemption to “accredited investors” within the meaning of Section 501(a) of Regulation D under the Securities Act or similar exemptions under state law. 

  
 2 

 (g) Investment Purposes. The Subscriber is purchasing the Shares solely for
investment purposes, for the Subscriber’s own account and not for the account or benefit of any other person, and not with a view towards the distribution or dissemination thereof. The Subscriber did not decide to enter into this Agreement as a
result of any general solicitation or general advertising within the meaning of Rule 502 under the Securities Act. 
 (h)
Restrictions on Transfer; Shell Company. Subscriber understands the Shares are being offered in a transaction not involving a public offering within the meaning of the Securities Act. Subscriber understands the Shares will be “restricted
securities” within the meaning of Rule 144(a)(3) under the Securities Act, and Subscriber understands that the certificates or book-entries representing the Shares will contain a legend in respect of
such restrictions. If in the future the Subscriber decides to offer, resell, pledge or otherwise transfer the Shares, such Shares may be offered, resold, pledged or otherwise transferred only pursuant to: (i) registration under the Securities
Act, or (ii) an available exemption from registration. Subscriber agrees that if any transfer of its Shares or any interest therein is proposed to be made, as a condition precedent to any such transfer, Subscriber may be required to deliver to
the Company an opinion of counsel satisfactory to the Company. Absent registration or an exemption, the Subscriber agrees not to resell the Shares. Subscriber further acknowledges that because the Company is a shell company, Rule 144 may not be
available to the Subscriber for the resale of the Shares until one year following consummation of the initial business combination of the Company, despite technical compliance with the requirements of Rule 144 and the release or waiver of any
contractual transfer restrictions. 
 (i) No Governmental Consents. No governmental, administrative or other third party consents or
approvals are required, necessary or appropriate on the part of Subscriber in connection with the transactions contemplated by this Agreement. 

Section 2.02 Company’s Representations, Warranties and Agreements. To induce the Subscriber to purchase the Shares, the
Company hereby represents and warrants to the Subscriber and agrees with the Subscriber as follows: 
 (a) Organization and Corporate
Power. The Company is a corporation duly organized, validly existing and in good standing under the laws of the State of Delaware. The Company possesses all requisite corporate power and authority necessary to carry out the transactions
contemplated by this Agreement. 
 (b) No Conflicts. The execution, delivery and performance of this Agreement and the consummation
by the Company of the transactions contemplated hereby do not violate, conflict with or constitute a default under (i) the Certificate of Incorporation or Bylaws of the Company, (ii) any agreement, indenture or instrument to which the
Company is a party or (iii) any law, statute, rule or regulation to which the Company is subject, or any agreement, order, judgment or decree to which the Company is subject, except, with respect to clauses (ii) and (iii) above, where such
violation, conflict or default would not reasonably be expected to have a material adverse effect on the financial condition, operating results or assets of the Company. 

  
 3 

 (c) Title to Securities. Upon issuance in accordance with, and payment pursuant to,
the terms hereof, the Shares will be duly and validly issued, fully paid and nonassessable. Upon issuance in accordance with, and payment pursuant to, the terms hereof, the Subscriber will have or receive good title to the Shares, free and clear of
all liens, claims and encumbrances of any kind, other than (i) transfer restrictions hereunder and other agreements to which the Shares may be subject which have been notified to the Subscriber in writing, (ii) transfer restrictions under
federal and state securities laws, and (iii) liens, claims or encumbrances imposed due to the actions of the Subscriber. 
 (d) No
Adverse Actions. There are no actions, suits, investigations or proceedings pending, threatened against or affecting the Company which: (i) seek to restrain, enjoin, prevent the consummation of or otherwise affect the transactions
contemplated by this Agreement or (ii) question the validity or legality of any transactions or seeks to recover damages or to obtain other relief in connection with any transactions. 

ARTICLE III. 
 FORFEITURE OF SHARES

 Section 3.01 Partial or No Exercise of the Over-allotment Option. In the event the Over-allotment Option granted to the
underwriters of the IPO is not exercised in full, the Subscriber acknowledges and agrees that it (or, if applicable, it and any transferees of Shares) shall forfeit any and all rights to such number of Shares (up to an aggregate of 1,500,000 Shares
and pro rata based upon the percentage of the Over-allotment Option exercised) such that immediately following such forfeiture, the Subscriber (and all other initial stockholders prior to the IPO, if any) will own an aggregate number of Shares, not
including any shares of the Company’s Class A Common Stock, par value $0.0001 per share (the “Class A Common Stock” and, together with the Class B Common Stock, the “Common Stock”),
issuable upon exercise of any warrants or any shares of Class A Common Stock purchased by Subscriber in the IPO or in the aftermarket, equal to twenty percent (20%) of the issued and outstanding shares of Common Stock immediately
following the IPO. 
 Section 3.02 Termination of Rights as Stockholder. If any of the Shares are forfeited in accordance with
this Article III, then after such time the Subscriber (or successor in interest), shall no longer have any rights as a holder of such forfeited Shares, and the Company shall take such action as is appropriate to cancel such forfeited
Shares. 
 Section 3.03 Share Certificates. In the event an adjustment to the Original Certificates, if any, is required
pursuant to this Article III, then the Subscriber shall return such Original Certificates to the Company or its designated agent as soon as practicable upon its receipt of notice from the Company advising Subscriber of such adjustment,
following which a new certificate (the “New Certificate”), if any, shall be issued in such amount representing the adjusted number of Shares held by the Subscriber. The New Certificate, if any, shall be returned to the
Subscriber as soon as practicable. Any such adjustment for any uncertificated securities held by the Subscriber shall be made in book-entry form. 

  
 4 

 ARTICLE IV. 

WAIVER OF LIQUIDATION DISTRIBUTIONS; REDEMPTION RIGHTS 

In connection with the Shares purchased pursuant to this Agreement, the Subscriber hereby waives any and all right, title, interest or claim
of any kind in or to any distributions by the Company from the trust account which will be established for the benefit of the Company’s public stockholders and into which substantially all of the proceeds of the IPO will be deposited (the
“Trust Account”), in the event of a liquidation of the Company upon the Company’s failure to timely complete an initial business combination. For purposes of clarity, in the event the Subscriber purchases any shares of
Class A Common Stock in the IPO or in the aftermarket, any such shares so purchased shall be eligible to receive any liquidating distributions by the Company. However, in no event will the Subscriber have the right to redeem any Shares into
funds held in the Trust Account upon the successful completion of an initial business combination. 
 ARTICLE V. 

RESTRICTIONS ON TRANSFER 

Section 5.01 Securities Law Restrictions. In addition to any restrictions to be contained in that certain letter agreement
(commonly known as an “Insider Letter”) to be dated as of the closing of the IPO by and between Subscriber and the Company, Subscriber agrees not to sell, transfer, pledge, hypothecate or otherwise dispose of all or any part of the
Shares unless, prior thereto (a) a registration statement on the appropriate form under the Securities Act and applicable state securities laws with respect to the Shares proposed to be transferred shall then be effective or (b) the
Company has received an opinion from counsel reasonably satisfactory to the Company, that such registration is not required because such transaction is exempt from registration under the Securities Act and the rules promulgated by the Securities and
Exchange Commission thereunder and with all applicable state securities laws. 
 Section 5.02
Lock-up. Subscriber acknowledges that the Securities will be subject to lock-up provisions (the “Lock-up”) contained in the Insider Letter. 

Section 5.03 Restrictive Legends. Any certificates representing the Shares shall have endorsed thereon legends substantially as
follows: 
 “THE SECURITIES REPRESENTED HEREBY HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED, OR ANY STATE SECURITIES LAWS AND
NEITHER THE SECURITIES NOR ANY INTEREST THEREIN MAY BE OFFERED, SOLD, TRANSFERRED, PLEDGED OR OTHERWISE DISPOSED OF EXCEPT PURSUANT TO AN EFFECTIVE REGISTRATION STATEMENT UNDER SUCH ACT OR SUCH LAWS OR AN EXEMPTION FROM REGISTRATION UNDER SUCH ACT
AND SUCH LAWS WHICH, IN THE OPINION OF COUNSEL, IS AVAILABLE.” 
 “THE SECURITIES REPRESENTED BY THIS CERTIFICATE ARE SUBJECT TO A LOCKUP AND MAY
NOT BE OFFERED, SOLD, TRANSFERRED, PLEDGED OR OTHERWISE DISPOSED DURING THE TERM OF THE LOCKUP.” 

  
 5 

 Section 5.04 Additional Shares or Substituted Securities. In the event of the
declaration of a share dividend, the declaration of an extraordinary dividend payable in a form other than Shares, a spin-off, a share split, an adjustment in conversion ratio, a recapitalization or a similar
transaction affecting the Company’s outstanding Shares without receipt of consideration, any new, substituted or additional securities or other property which are by reason of such transaction distributed with respect to any Shares subject to
this Article V or into which such Shares thereby become convertible shall immediately be subject to this Article V and Article III. Appropriate adjustments to reflect the distribution of such securities or
property shall be made to the number and/or class of Shares subject to this Article V and Article III. 

Section 5.05 Registration Rights. Subscriber acknowledges that the Shares are being purchased pursuant to an exemption from the
registration requirements of the Securities Act and will become freely tradable only after certain conditions are met or they are registered pursuant to a registration rights agreement to be entered into with the Company in connection with the
closing of the IPO (the “Registration Rights Agreement”). 
 ARTICLE VI. 

OTHER AGREEMENTS 

Section 6.01 Further Assurances. Subscriber agrees to execute such further instruments and to take such further action as may
reasonably be necessary to carry out the intent of this Agreement.

documents which are required or contemplated by this Agreement shall be: (i) in writing and delivered personally or sent by first class registered or certified mail, overnight courier service or facsimile or electronic transmission to
the address designated in writing, (ii) by facsimile to the number most recently provided to such party or such other address or fax number as may be designated in writing by such party and (iii) by electronic mail, to the

(5) days after mailing if sent by mail. 
 Section 6.03 Entire Agreement. This Agreement, together with the Insider
Letter and the Registration Rights Agreement, each substantially in the form to be filed as an exhibit to the Registration Statement on Form S-1 associated with the Company’s IPO, embodies the entire agreement and understanding between the
Subscriber and the Company with respect to the subject matter hereof and supersedes all prior oral or written agreements and understandings relating to the subject matter hereof. No statement, representation, warranty, covenant or agreement of any
kind not expressly set forth in this Agreement shall affect, or be used to interpret, change or restrict, the express terms and provisions of this Agreement. 

Section 6.04 Modifications and Amendments. The terms and provisions of this Agreement may be modified or amended only by written
agreement executed by all parties hereto. 

  
 6 

 Section 6.05 Waivers and Consents. The terms and provisions of this Agreement
may be waived, or consent for the departure therefrom granted, only by a written document executed by the party entitled to the benefits of such terms or provisions. No such waiver or consent shall be deemed to be or shall constitute a waiver or
consent with respect to any other terms or provisions of this Agreement, whether or not similar. Each such waiver or consent shall be effective only in the specific instance and for the purpose for which it was given, and shall not constitute a
continuing waiver or consent. 
 Section 6.06 Assignment. The rights and obligations under this Agreement may not be assigned by
either party hereto without the prior written consent of the other party. 
 Section 6.07 Benefit. All statements,
representations, warranties, covenants and agreements in this Agreement shall be binding on the parties hereto and shall inure to the benefit of the respective successors and permitted assigns of each party hereto. Nothing in this Agreement shall be
construed to create any rights or obligations except among the parties hereto, and no person or entity shall be regarded as a third-party beneficiary of this Agreement. 

Section 6.08 Governing Law. This Agreement and the rights and obligations of the parties hereunder shall be construed in
accordance with and governed by the laws of New York applicable to contracts wholly performed within the borders of such state, without giving effect to the conflict of law principles thereof. 

Section 6.09 Severability. In the event that any court of competent jurisdiction shall determine that any provision, or any
portion thereof, contained in this Agreement shall be unreasonable or unenforceable in any respect, then such provision shall be deemed limited to the extent that such court deems it reasonable and enforceable, and as so limited shall remain in full
force and effect. In the event that such court shall deem any such provision, or portion thereof, wholly unenforceable, the remaining provisions of this Agreement shall nevertheless remain in full force and effect. 

Section 6.10 No Waiver of Rights, Powers and Remedies. No failure or delay by a party hereto in exercising any right, power or
remedy under this Agreement, and no course of dealing between the parties hereto, shall operate as a waiver of any such right, power or remedy of such party. No single or partial exercise of any right, power or remedy under this Agreement by a party
hereto, nor any abandonment or discontinuance of steps to enforce any such right, power or remedy, shall preclude such party from any other or further exercise thereof or the exercise of any other right, power or remedy hereunder. The election of
any remedy by a party hereto shall not constitute a waiver of the right of such party to pursue other available remedies. No notice to or demand on a party not expressly required under this Agreement shall entitle the party receiving such notice or
demand to any other or further notice or demand in similar or other circumstances or constitute a waiver of the rights of the party giving such notice or demand to any other or further action in any circumstances without such notice or demand. 

Section 6.11 Survival of Representations and Warranties. All representations and warranties made by the parties hereto in this
Agreement or in any other agreement, certificate or instrument provided for or contemplated hereby, shall survive the execution and delivery hereof and any investigations made by or on behalf of the parties. 

  
 7 

 Section 6.12 No Broker or Finder. Each of the parties hereto represents and
warrants to the other that no broker, finder or other financial consultant has acted on its behalf in connection with this Agreement or the transactions contemplated hereby in such a way as to create any liability on the other. Each of the parties
hereto agrees to indemnify and save the other harmless from any claim or demand for commission or other compensation by any broker, finder, financial consultant or similar agent claiming to have been employed by or on behalf of such party and to
bear the cost of legal expenses incurred in defending against any such claim. 
 Section 6.13 Headings and Captions. The
headings and captions of the various subdivisions of this Agreement are for convenience of reference only and shall in no way modify or affect the meaning or construction of any of the terms or provisions hereof. 

Section 6.14 Counterparts. This Agreement may be executed in one or more counterparts, all of which when taken together shall be
considered one and the same agreement and shall become effective when counterparts have been signed by each party and delivered to the other party, it being understood that both parties need not sign the same counterpart. In the event that any
signature is delivered by facsimile transmission or any other form of electronic delivery, such signature shall create a valid and binding obligation of the party executing (or on whose behalf such signature is executed) with the same force and
effect as if such signature page were an original thereof. 
 Section 6.15 Construction. The parties hereto have participated
jointly in the negotiation and drafting of this Agreement. If an ambiguity or question of intent or interpretation arises, this Agreement will be construed as if drafted jointly by the parties hereto and no presumption or burden of proof will arise
favoring or disfavoring any party hereto because of the authorship of any provision of this Agreement. The words “include,” “includes,” and “including” will be deemed to be followed by
“without limitation.” Pronouns in masculine, feminine, and neuter genders will be construed to include any other gender, and words in the singular form will be construed to include the plural and vice versa, unless the context
otherwise requires. The words “this Agreement,” “herein,” “hereof,” “hereby,” “hereunder,” and words of similar import refer to this Agreement as a whole and not to
any particular subdivision unless expressly so limited. The parties hereto intend that each representation, warranty, and covenant contained herein will have independent significance. If any party hereto has breached any representation, warranty, or
covenant contained herein in any respect, the fact that there exists another representation, warranty or covenant relating to the same subject matter (regardless of the relative levels of specificity) which such party hereto has not breached will
not detract from or mitigate the fact that such party hereto is in breach of the first representation, warranty, or covenant. 

Section 6.16 Mutual Drafting. This Agreement is the joint product of the Subscriber and the Company and each provision hereof has
been subject to the mutual consultation, negotiation and agreement of such parties and shall not be construed for or against any party hereto.

Company’s stockholders and shall not seek redemption with respect to such Shares. Additionally, the Subscriber agrees not to tender any Shares in connection with a tender offer presented to the Company’s stockholders in connection with an
initial business combination negotiated by the Company. 
 ARTICLE VIII. 

INDEMNIFICATION 
 Each party shall
indemnify the other against any loss, cost or damages (including reasonable attorney’s fees and expenses) incurred as a result of such party’s breach of any representation, warranty, covenant or agreement in this Agreement.

 Exhibit 10.8 

FORM OF FORWARD PURCHASE AGREEMENT 

This Forward Purchase Agreement (this “Agreement”) is entered into as of September 25, 2020, by and between Supernova
Partners Acquisition Company, Inc., a Delaware corporation (the “Company”) and [            ] an affiliate of
[                ], a Co-Chairman of the Company (the “Purchaser”). 

WHEREAS, the Company was incorporated for the purpose of effecting a merger, stock exchange, asset acquisition, stock purchase, reorganization
or similar business combination with one or more businesses (a “Business Combination”); 
 WHEREAS, the Company has
confidentially submitted to the U.S. Securities and Exchange Commission (the “SEC”) a draft registration statement on Form S-1 (the “Registration Statement”) for its initial
public offering (“IPO”) of units (the “Public Units”) at a price of $10.00 per Public Unit, each comprised of one share of Class A common stock of the Company, par value $0.0001 per share (the
“Class A Share(s)”), and one-third of one redeemable warrant, where each whole redeemable warrant is exercisable to purchase one Class A Share at an exercise price of
$11.50 per share (the “Warrant(s)”). Only whole Warrants are exercisable. A holder of Warrants will not be able to exercise any fraction of a Warrant. The Company shall not issue fractional Warrants other than as part of the Public
Units. If, upon the detachment of the Warrants from the Public 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; 
 WHEREAS, following the closing of the IPO (the “IPO Closing”), the Company will seek to identify and
consummate a Business Combination; and 
 WHEREAS, the parties wish to enter into this Agreement, pursuant to which immediately prior to the
closing of the Company’s initial Business Combination (the “Business Combination Closing”), the Company shall issue and sell, and the Purchaser shall purchase, on a private placement basis,
[                ] Class A Shares (the “Forward Purchase Shares”) and
[                ] Warrants (the “Forward Purchase Warrants” and together with the Forward Purchase Shares, the “Forward Purchase
Securities”) on the terms and conditions set forth herein; 
 NOW, THEREFORE, in consideration of the premises, representations,
warranties and the mutual covenants contained in this Agreement, and for other good and valuable consideration, the receipt, sufficiency and adequacy of which are hereby acknowledged, the parties hereto agree as follows: 

1.    Sale and Purchase. 

(a)    Forward Purchase Securities. 

(i)    The Company shall issue and sell to the Purchaser, and the Purchaser shall purchase from the Company, the Forward
Purchase Shares and the Forward Purchase Warrants for an aggregate purchase price of $[            ] (the “FPS Purchase Price”). 

 (ii)    Each Forward Purchase Warrant will have the same terms as each
Warrant sold as part of the Public Units in the IPO (“Public Warrants”), and will be subject to the terms and conditions of the Warrant Agreement to be entered into between the Company and Continental Stock Transfer & Trust
Company, as Warrant Agent, in connection with the IPO (the “Warrant Agreement”). Each Forward Purchase Warrant will entitle the holder thereof to purchase one Class A Share at a price of $11.50 per share, subject to adjustment
as described in the Warrant Agreement, and only whole Forward Purchase Warrants will be exercisable. The Forward Purchase Warrants will become exercisable on the later of 30 days after the Business Combination Closing and 12 months from the closing
of the IPO, and will expire five years after the Business Combination Closing or earlier upon redemption or the liquidation of the Company, as described in the Warrant Agreement. 

(iii)    The Company shall require the Purchaser to purchase the Forward Purchase Securities by delivering notice to the
Purchaser, at least five (5) Business Days before the Business Combination Closing, specifying the date of the Business Combination Closing and instructions for wiring the FPS Purchase Price. The closing of the sale of the Forward Purchase
Securities (the “FPS Closing”) shall be held on the same date and immediately prior to the Business Combination Closing (such date being referred to as the “FPS Closing Date”). At least one (1) Business Day
prior to the FPS Closing Date, the Purchaser shall deliver to the Company, to be held in escrow until the FPS Closing, the FPS Purchase Price for the Forward Purchase Securities by wire transfer of U.S. dollars in immediately available funds to the
account specified by the Company in such notice. Immediately prior to the FPS Closing on the FPS Closing Date, (A) the FPS Purchase Price shall be released from escrow automatically and without further action by the Company or the Purchaser,
and (B) upon such release, the Company shall issue the Forward Purchase Securities (individually or collectively, the “Securities”) to the Purchaser in book-entry form, free and clear of any liens or other restrictions
whatsoever (other than those arising under state or federal securities laws), registered in the name of the Purchaser (or its nominee in accordance with its delivery instructions), or to a custodian designated by the Purchaser, as applicable. In the
event the Business Combination Closing does not occur on the date scheduled for closing, the FPS Closing shall not occur and the Company shall promptly (but not later than one (1) Business Day thereafter) return the FPS Purchase Price to the
Purchaser. For the purposes of this Agreement, “Business Day” means any day, other than a Saturday or a Sunday, that is neither a legal holiday nor a day on which banking institutions are generally authorized or required by law
or regulation to close in the City of New York, New York. 
 (b)    Legend. Each register and book entry for the
Securities shall contain a notation, and each certificate (if any) evidencing the Securities shall be stamped or otherwise imprinted with a legend, in substantially the following form: 

“THE SECURITIES REPRESENTED HEREBY HAVE NOT BEEN REGISTERED UNDER THE U.S. SECURITIES ACT OF 1933, AS AMENDED, OR THE SECURITIES LAWS OF
ANY STATE OR OTHER JURISDICTION, AND MAY NOT BE TRANSFERRED IN VIOLATION OF SUCH ACT AND LAWS.” 

  
 2 

 (c)    Legend Removal. If the Securities are eligible to be sold
without restriction under, and without the Company being in compliance with the current public information requirements of, Rule 144 under the Securities Act of 1933, as amended (the “Securities Act”), then at the Purchaser’s
request, the Company will, at its sole expense, cause the Company’s transfer agent to remove the legend set forth in Section 1(b). In connection therewith, if required by the Company’s transfer agent, the Company
will promptly cause an opinion of counsel to be delivered to and maintained with its transfer agent, together with any other authorizations, certificates and directions required by the transfer agent that authorize and direct the transfer agent to
transfer such Securities without any such legend; provided, however, that the Company will not be required to deliver any such opinion, authorization or certificate or direction if it reasonably believes that removal of the legend
could reasonably be expected to result in or facilitate transfers of Securities in violation of applicable law. 

(d)    Registration Rights. The Purchaser shall have registration rights with respect to the Forward Purchase
Securities as set forth on Exhibit A hereto (the “Registration Rights”). 

2.    Representations and Warranties of the Purchaser. The Purchaser represents and warrants to the Company
as follows, as of the date hereof: 
 (a)    Organization and Power. The Purchaser is duly organized, validly
existing, and in good standing under the laws of the jurisdiction of incorporation or organization and has all requisite power and authority to carry on its business as presently conducted and as proposed to be conducted. 

(b)    Authorization. The Purchaser has full power and authority to enter into this Agreement. This Agreement, when
executed and delivered by the Purchaser, will constitute the valid and legally binding obligation of the Purchaser, enforceable in accordance with its terms, except (a) as limited by applicable bankruptcy, insolvency, reorganization,
moratorium, fraudulent conveyance and any other laws of general application affecting enforcement of creditors’ rights generally, (b) as limited by laws relating to the availability of specific performance, injunctive relief or other
equitable remedies, or (c) to the extent the indemnification provisions contained in the Registration Rights may be limited by applicable federal or state securities laws. 

(c)    Governmental Consents and Filings. No consent, approval, order or authorization of, or registration,
qualification, designation, declaration or filing with, any federal, state or local governmental authority is required on the part of the Purchaser in connection with the consummation of the transactions contemplated by this Agreement. 

(d)    Compliance with Other Instruments. The execution, delivery and performance by the Purchaser of this
Agreement and the consummation by the Purchaser of the transactions contemplated by this Agreement will not result in any violation or default (i) of any provisions of its organizational documents, (ii) of any instrument, judgment, order,
writ or decree to which it is a party or by which it is bound, (iii) under any note, indenture or mortgage to which it is a party or by which it is bound, (iv) under any lease, agreement, contract or purchase order to which it is a party
or by which it is bound or (v) of any provision of federal or state statute, 

  
 3 

 
rule or regulation applicable to the Purchaser, in each case (other than clause (i)), which would have a material adverse effect on the Purchaser or its ability to consummate the transactions
contemplated by this Agreement. 
 (e)    Purchase Entirely for Own Account. This Agreement is made with the
Purchaser in reliance upon the Purchaser’s representation to the Company, which by the Purchaser’s execution of this Agreement, the Purchaser hereby confirms, that the Forward Purchase Securities to be acquired by the Purchaser will be
acquired for investment for the Purchaser’s own account, not as a nominee or agent, and not with a view to the resale or distribution of any part thereof, and that the Purchaser has no present intention of selling, granting any participation
in, or otherwise distributing the same in violation of law. By executing this Agreement, the Purchaser further represents that the Purchaser does not presently have any contract, undertaking, agreement or arrangement with any Person to sell,
transfer or grant participations to such Person or to any third Person, with respect to any of the Forward Purchase Securities. For purposes of this Agreement, “Person” means an individual, a limited liability company, a
partnership, a joint venture, a corporation, a trust, an unincorporated organization, any other entity or any government or any department or agency thereof. 

(f)    Disclosure of Information. The Purchaser has had an opportunity to discuss the Company’s business,
management, financial affairs and the terms and conditions of the offering of the Forward Purchase Securities, as well as the terms of the Company’s proposed IPO, with the Company’s management. 

(g)    Restricted Securities. The Purchaser understands that the offer and sale of the Forward Purchase Securities
to the Purchaser has not been, and will not be, registered under the Securities Act, by reason of a specific exemption from the registration provisions of the Securities Act which depends upon, among other things, the bona fide nature of the
investment intent and the accuracy of the Purchaser’s representations as expressed herein. The Purchaser understands that the Forward Purchase Securities are “restricted securities” under applicable U.S. federal and state securities
laws and that, pursuant to these laws, the Purchaser must hold the Forward Purchase Securities indefinitely unless they are registered with the SEC and qualified by state authorities, or an exemption from such registration and qualification
requirements is available. The Purchaser acknowledges that the Company has no obligation to register or qualify the Forward Purchase Securities, or any Class A Shares into which the Forward Purchase Securities may be converted into or exercised
for, for resale, except pursuant to the Registration Rights. The Purchaser further acknowledges that if an exemption from registration or qualification is available, it may be conditioned on various requirements including, but not limited to, the
time and manner of sale, the holding period for the Forward Purchase Securities, and on requirements relating to the Company which are outside of the Purchaser’s control, and which the Company is under no obligation and may not be able to
satisfy. The Purchaser acknowledges that the Company confidentially submitted the Registration Statement for its proposed IPO to the SEC for review. The Purchaser understands that the offering of the Forward Purchase Securities is not, and is not
intended to be, part of the IPO, and that the Purchaser will not be able to rely on the protection of Section 11 of the Securities Act with respect to such Forward Purchase Securities. 

  
 4 

 (h)    No Public Market. The Purchaser understands that no public
market now exists for the Securities, and that the Company has made no assurances that a public market will ever exist for the Securities. 

(i)    High Degree of Risk. The Purchaser understands that its agreement to purchase the Securities involves a high
degree of risk which could cause the Purchaser to lose all or part of its investment. 
 (j)    Accredited
Investor. The Purchaser is an “accredited investor” as defined in Rule 501(a) of Regulation D promulgated under the Securities Act. 

(k)    No General Solicitation. Neither the Purchaser, nor any of its officers, directors, employees, agents,
stockholders or partners has either directly or indirectly, including, through a broker or finder (i) to its knowledge, engaged in any general solicitation, or (ii) published any advertisement in connection with the offer and sale of the
Forward Purchase Securities. 
 (l)    Non-Public Information. The
Purchaser acknowledges its obligations under applicable securities laws with respect to the treatment of material non-public information relating to the Company. 

(m)    Adequacy of Financing. The Purchaser has, or will have prior to the FPS Closing Date, available to it
sufficient funds to satisfy its obligations under this Agreement. 
 (n)    Affiliation of Certain FINRA Members.
The Purchaser is neither a person associated nor affiliated with J.P. Morgan Securities LLC (“JPM”), Jefferies LLC (“Jefferies”) or, to its actual knowledge, any other member of the Financial Industry Regulatory
Authority (“FINRA”) that is participating in the IPO. 
 (o)    No Other Representations and
Warranties; Non-Reliance. Except for the specific representations and warranties contained in this Section 2 and in any certificate or agreement delivered pursuant hereto, none of
the Purchaser nor any person acting on behalf of the Purchaser nor any of the Purchaser’s affiliates (the “Purchaser Parties”) has made, makes or shall be deemed to make any other express or implied representation or warranty

the fact that there exists another representation, warranty or covenant relating to the same subject matter (regardless of the relative levels of specificity) which such party hereto has not breached will not detract from or mitigate the fact that
such party hereto is in breach of the first representation, warranty, or covenant. 
 (p)    Waiver. No waiver by
any party hereto of any default, misrepresentation, or breach of warranty or covenant hereunder, whether intentional or not, may be deemed to extend to any prior or subsequent default, misrepresentation, or breach of warranty or covenant hereunder
or affect in any way any rights arising because of any prior or subsequent occurrence. 
 (q)    Confidentiality.
Except as may be required by law, regulation or applicable stock exchange listing requirements, unless and until the transactions contemplated hereby and the terms hereof are publicly announced or otherwise publicly disclosed by the Company, the
parties hereto shall keep confidential and shall not publicly disclose the existence or terms of this Agreement. 

(r)    Specific Performance. The Purchaser agrees that irreparable damage may occur in the event any provision of
this Agreement was not performed by the Purchaser in accordance with the terms hereof and that the Company shall be entitled to specific performance of the terms hereof, in addition to any other remedy at law or equity.

 Exhibit A 

Registration Rights 

1.    Within thirty (30) days after the Business Combination Closing, the Company shall use commercially
reasonable efforts (i) to file a registration statement on Form S-1, to the extent the Company is required to use such form, for a secondary offering (including any successor registration statement
covering the resale of the Registrable Securities, a “Resale Shelf”) of (x) the Class A Shares and Warrants (and underlying Class A Shares) comprising the Forward Purchase Securities, (y) any other Class A
Shares that may be acquired by the Purchaser after the date of this Agreement, including any time after the Business Combination Closing, and (z) any other equity security of the Company issued or issuable with respect to the securities
referred to in clauses (x) and (y) by way of a stock dividend or stock split or in connection with a combination of shares, recapitalization, merger, consolidation or reorganization (collectively, for so long as such securities are held by the
Purchaser or its assignees under the Agreement, each a “Holder”), the “Registrable Securities”) pursuant to Rule 415 under the Securities Act; provided, that, if Form
S-3 is available for such a registration, the Company shall register the resale of the Registrable Securities on Form S-3 as soon as such form is available and such Form
S-3 shall also be deemed to be a Resale Shelf, (ii) to cause the Resale Shelf to be declared effective under the Securities Act promptly thereafter, but in no event later than sixty (60) days after
the initial filing of the Resale Shelf, and (iii) to maintain the effectiveness of such Resale Shelf with respect to the Purchaser’s Registrable Securities until the earliest of (A) the date on which the Purchaser or its respective
assignees cease to hold Registrable Securities covered by such Resale Shelf, and (B) the date all of the Purchaser’s Registrable Securities covered by the Resale Shelf can be sold publicly without restriction or limitation (including
without volume or manner of sale restrictions) under Rule 144 under the Securities Act. 
 2.    The Holders may,
after the Resale Shelf becomes effective, deliver a written notice to the Company (the “Underwritten Offering Notice”) specifying that the sale of some or all of the Registrable Securities subject to the Resale Shelf is intended to
be conducted through a firm commitment underwritten offering (an “Underwritten Offering”); provided, however, that the Holders of Registrable Securities may not, without the Company’s prior written
consent, (i) launch an Underwritten Offering the anticipated gross proceeds of which shall be less than $10,000,000 (unless the Holders are proposing to sell all of their remaining Registrable Securities), (ii) launch more than three
Underwritten Offerings at the request of the Holders, (iii) launch more than two Underwritten Offerings within any three-hundred sixty-five (365) day-period) or (iv) launch an Underwritten
Offering within the period commencing fourteen (14) days prior to and ending two (2) days following the Company’s scheduled earnings release date for any fiscal quarter or year. In the event of an Underwritten Offering, the Holders
representing a majority-in-interest of the Registrable Securities to be included in such Underwritten Offering shall select the managing underwriter(s) for the
Underwritten Offering; provided that the choice of such managing underwriter(s) shall be subject to the consent of the Company, which is not to be unreasonably withheld, conditioned or delayed. If the underwriter(s) for any
Underwritten Offering pursuant to this paragraph 2 of this Exhibit A (each, a “Secondary Offering”) advise the Company and the Holders that, in their good faith opinion, marketing factors require a limitation on the number of
securities that may be included in such Secondary Offering, the number of securities to be so included shall be allocated as follows: (i) first, to the Holders that have requested to participate in such Secondary Offering, allocated pro
rata among such Holders on 

  
 A-1 

 
the basis of the percentage of the Registrable Securities requested to be included in such Secondary Offering by such Holders, and (ii) second, to the holders of any other securities of the
Company that have been requested to be so included. 
 3.    Upon receipt of prior written notice by any Holder
that they intend to effect a sale of Registrable Securities held by them as are then registered pursuant to the Resale Shelf, the Company shall use its reasonable best efforts to cooperate in such sale (whether or not such sale constitutes an
Underwritten Offering), including by amending or supplementing the prospectus related to such Resale Shelf as may be reasonably requested by such Holder for so long as such Holder holds Registrable Securities. 

4.    In the event the Company is prohibited by applicable rule, regulation or interpretation by the staff
(“Staff”) of the Securities and Exchange Commission (“SEC”) from registering all of the Registrable Securities on the Resale Shelf or the Staff requires that any Holder be specifically identified as an
“underwriter” in order to permit such registration statement to become effective, and such Holder does not consent in writing to being so named as an underwriter in such registration statement, the number of Registrable Securities to be
registered on the Resale Shelf will be reduced on a pro rata basis among all Holders to be so included, unless otherwise required by the Staff, so that the number of Registrable Securities to be registered is permitted by the Staff and such Holder
is not required to be named as an “underwriter”; provided, that, any Registrable Securities not registered due to this paragraph 4 shall thereafter as soon as allowed by the SEC guidance be registered to the extent the
prohibition no longer is applicable. 
 5.    If at any time the Company proposes to file a registration
statement (a “Registration Statement”) on its own behalf, or on behalf of any Persons other than the Holders who have registration rights (“Other Holders”), relating to an Underwritten Offering of shares of common
stock (a “Company Offering”), then the Company will provide the Holders with notice in writing (an “Offer Notice”) at least five (5) Business Days prior to such filing, which Offer Notice will offer to include
in the Registration Statement the Registrable Securities held by each Holder. Within three (3) Business Days after receiving the Offer Notice, each Holder may make a written request to the Company to include some or all of such Holder’s
Registrable Securities in the Registration Statement. If the underwriter(s) for any Company Offering advise the Company that, in their good faith opinion, marketing factors require a limitation on the number of securities that may be included in the
Company Offering, the number of securities to be so included shall be allocated as follows: (i) first, to the Company and the Other Holders, if any; and (ii) second, to the Holders. 

6.     In connection with any Underwritten Offering, the Company shall enter into such customary agreements and
take all such other actions in connection therewith (including those reasonably requested by Holders representing a majority-in-interest of the Registrable Securities to
be included in such Underwritten Offering) in order to facilitate the disposition of such Registrable Securities as are reasonably necessary or required, and in such connection enter into a customary underwriting agreement that provides for
customary opinions, comfort letters and officer’s certificates and other customary deliverables. 

  
 A-2 

 7.    At any time during which the Company has an effective
Resale Shelf with respect to the Purchaser’s Registrable Securities, the Purchaser may make a written request (which request shall specify the intended method of disposition thereof) (a “Shelf Takedown Request”) to the Company
to effect a sale, of all or a portion of the Purchaser’s Registrable Securities that are covered by the Resale Shelf, and the Company shall use commercially reasonable efforts to file a prospectus supplement for such purpose as soon as
reasonably practicable following receipt of a Shelf Takedown Request. 
 8.    The Company shall pay all fees and
expenses incident to the performance of or compliance with its obligation to prepare, file and maintain the Resale Shelf (including the fees of its counsel and accountants). The Company shall also pay all Registration Expenses. For purposes of this
paragraph 7, “Registration Expenses” shall mean the out-of-pocket expenses of any Secondary Offering and any Company Offering, including, without
limitation, the following: (i) all registration and filing fees (including fees with respect to filings required to be made with FINRA) and any securities exchange on which the Registrable Securities are then listed; (ii) fees and expenses
of compliance with securities or blue sky laws (including reasonable fees and disbursements of counsel for the underwriters in connection with blue sky qualifications of the Registrable Securities); (iii) printing, messenger, telephone and delivery
expenses; (iv) reasonable fees and disbursements of counsel for the Company; and (v) reasonable and documented fees and expenses of one legal counsel selected by Holders representing a majority-in-interest of the Registrable Securities participating in any such Secondary Offering or Company Offering, who will represent all the selling shareholders. 

9.    The Company may suspend the use of a prospectus included in the Resale Shelf by furnishing to each Holder a
written notice (“Suspension Notice”) stating that in the good faith judgment of the Company, it would be either (i) prohibited by the Company’s insider trading policy (as if the Holders were covered by such policy) or
(ii) materially detrimental to the Company and its stockholders for such prospectus to be used at such time. The Company’s right to suspend the use of such prospectus under clause (ii) of the preceding sentence may be exercised for a
period of not more than sixty (60) days after the date of such notice to the Holders; provided, such period may be extended for an additional thirty (30) days with the consent of a majority-in-interest of the Holders of Registrable Securities covered by the Resale Shelf, which consent shall not be unreasonably withheld; provided, further, that such right to suspend the use of a
prospectus shall be exercised by the Company not more than twice in any twelve (12) month period. A Holder of Registrable Securities shall not effect any sales of Registrable Securities pursuant to the Resale Shelf at any time after it has
received a Suspension Notice from the Company and prior to receipt of an End of Suspension Notice (as defined below). The Holders may recommence effecting sales of the Registrable Securities pursuant to the Resale Shelf following further written
notice to such effect (an “End of Suspension Notice”) from the Company to the Holders. The Company shall act in good faith to permit any suspension period contemplated by this paragraph 8 to be concluded as promptly as reasonably
practicable. 
 10.    The Holders agree that, except as required by applicable law, the Purchaser shall treat as
confidential the receipt of any Suspension Notice (provided, that, in no event shall such notice contain any material nonpublic information of the Company) hereunder and shall not disclose or use the information contained in such
Suspension Notice without the prior written 

  
 A-3 

 
consent of the Company until such time as the information contained therein is or becomes public, other than as a result of disclosure by a Holder of Registrable Securities in breach of the terms
of this Agreement. 
 11.    The Company shall indemnify and hold harmless the Holders, their respective
directors and officers, partners, members, managers, employees, agents, and representatives and each person, if any, who controls a Holder within the meaning of the Securities Act and the Exchange Act and any agent thereof (collectively,
“Indemnified Persons”), to the fullest extent permitted by applicable law, from and against any losses, claims, damages, liabilities, joint or several, costs (including reasonable costs of preparation and reasonable attorneys’
fees) and expenses, judgments, fines, penalties, interest, settlements or other amounts arising from any and all claims, demands, actions, suits or proceedings, whether civil, criminal, administrative or investigative, in which any Indemnified
Person may be involved, or is threatened to be involved, as a party or otherwise, under the Securities Act or otherwise (collectively, “Losses”), promptly as incurred, arising out of, based upon or resulting from any untrue
statement or alleged untrue statement of any material fact contained in the Resale Shelf (or any amendment or supplement thereto), the related prospectus, or any amendment or supplement thereto, or arise out of, are based upon or resulting from the
omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein, in light of the circumstances in which they were made, not misleading; provided, however, that the
Company shall not be liable in any such case or to any Indemnified Person to the extent that any such Loss arises out of, is based upon or results from an untrue statement or alleged untrue statement or omission or alleged omission or so made in
reliance upon or in conformity with information furnished by or on behalf of such Indemnified Person in writing specifically for use in the preparation of the Resale Shelf, the related prospectus, or any amendment or supplement thereto. Such
indemnity shall remain in full force and effect regardless of any investigation made by or on behalf of such Indemnified Person, and shall survive the transfer of such securities by the Holders. 

12.    The Company’s obligation under paragraph (1) of this Exhibit A is subject to each Holder’s
furnishing to the Company in writing such information as the Company reasonably requests for use in connection with the Resale Shelf, the related prospectus, or any amendment or supplement thereto. Each Holder shall indemnify the Company, its
officers, directors, managers, employees, agents and representatives, and each person who controls the Company (within the meaning of the Securities Act) against any losses, claims, damages, liabilities and expenses resulting from any untrue
statement or alleged untrue statement of material fact contained in the Resale Shelf, the related prospectus, or any amendment or supplement thereto or any omission or alleged omission of a material fact required to be stated therein or necessary to
make the statements therein not misleading, but only to the extent that such untrue statement or omission is contained in any information so furnished in writing by such Holder expressly for inclusion in such document; provided, that,
the obligation to indemnify shall be individual, not joint and several, with respect to the Holders and the Other Holders and shall be limited to the net amount of proceeds received by each Holder and each Other Holder from the sale of Registrable
Securities pursuant to the Resale Shelf. 
 13.    The Company shall cooperate with the Holders, to the extent
the Registrable Securities become freely tradable, to facilitate the timely preparation and delivery of certificates 

  
 A-4 

 
(not bearing any restrictive legend) representing the Registrable Securities to be offered pursuant to a Resale Shelf and enable such certificates to be in such denominations or amounts, as the
case may be, as the Holders may reasonably request and registered in such names as each Holder may request. 

14.    If requested by the Holders representing a majority in interest of the Registrable Securities, the Company
shall as soon as practicable, subject to any Suspension Notice, (i) incorporate in a prospectus supplement or post-effective amendment such information as each Holder reasonably requests to be included therein relating to the sale and
distribution of Registrable Securities, including, without limitation, information with respect to the number of Registrable Securities being offered or sold, the purchase price being paid therefor and any other terms of the offering of the
Registrable Securities to be sold in such offering; (ii) make all required filings of such prospectus supplement or post-effective amendment after being notified of the matters to be incorporated in such prospectus supplement or post-effective
amendment; and (iii) supplement or make amendments to any Registration Statement if reasonably requested by the Holders representing a majority in interest of the Registrable Securities. 

15.    As long as the Registrable Securities are outstanding, the Company, at all times while it shall be reporting
under the Exchange Act, covenants to file timely (or obtain extensions in respect thereof and file within the applicable grace period) all reports required to be filed by the Company after the date hereof pursuant to Sections 13(a) or 15(d) of the
Exchange Act, and to promptly furnish the Holders with true and complete copies of all such filings, unless filed through the SEC’s EDGAR system. The Company further covenants that it shall take such further action as the Holders may reasonably
request, all to the extent required from time to time, to enable the Holders to sell the Class A Shares and Warrants held by the Holders without registration under the Securities Act within the limitation of the exemptions provided by Rule 144
promulgated under the Securities Act, including providing any legal opinions. Upon the request of any Holder, the Company shall deliver to such Holder a written certification of a duly authorized officer as to whether it has complied with such
requirements. 
 16.    The rights, duties and obligations of the Purchaser under this Exhibit A may be assigned
or delegated by the Purchaser in conjunction with and to the extent of any permitted transfer or assignment of Registrable Securities by the Purchaser to any permitted transferee or assignee.
