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

days. 
 6.    Remedies. 

(a)    Upon the occurrence of an Event of Default specified in Section 5(a) hereof, Payee may, by written notice to

virtue of any present or future laws exempting any property, real or personal, or any part of the proceeds arising from 

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

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

	 	RE:	 Securities Subscription Agreement 

Ladies and Gentlemen: 
 This agreement (the
“Agreement”) is entered into on December 22, 2020 by and between Supernova Partners II LLC, a Cayman Islands limited liability company (the “Subscriber” or “you”), and Supernova Partners Acquisition
Company II, Ltd., a Cayman Islands exempted company (the “Company”). Pursuant to the terms hereof, the Company hereby accepts the offer the Subscriber has made to subscribe for and purchase 5,750,000 Class B ordinary shares
$0.0001 par value per share (the “Shares”), up to 750,000 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: 

 

	1.	 SUBSCRIPTION AND PURCHASE OF SECURITIES. 

1.1    Subscription and 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 subscribes for and purchases the Shares from the Company, 750,000 of which are 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 effect such delivery in book-entry form. All references in this Agreement to
shares of the Company being forfeited shall take effect as surrenders for no consideration of such shares as a matter of Cayman Islands law. 

1.2    Surrender of Class B Ordinary Share. Upon the issue of the Shares, the Subscriber hereby
surrenders to the Company for no consideration the one Class B ordinary share held by the Subscriber following the incorporation of the Company. 
  

	2.	 REPRESENTATIONS, WARRANTIES AND AGREEMENTS. 

2.1    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: 

2.1.1    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. 

2.1.2    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 limited liability company agreement 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. 
 2.1.3    Formation, Registration and
Authority. The Subscriber is a Cayman Islands limited liability company, validly existing and in good standing under the laws of the Cayman Islands 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 will be 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). 
 2.1.4    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 of 1933, as amended (the “Securities Act”) 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. 
 2.1.5    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 Section 2 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. 
 2.1.6    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, 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. 

2.1.7    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 in violation of the registration requirements of the Securities Act. 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 of Regulation D under the Securities Act. 

  
 2 

 2.1.8    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. 

2.1.9    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. 

2.2     Company’s Representations, Warranties and Agreements. To induce the Subscriber to subscribe for and
purchase the Shares, the Company hereby represents and warrants to the Subscriber and agrees with the Subscriber as follows: 

2.2.1    Incorporation and Corporate Power. The Company is a Cayman Islands exempted company and is
qualified to do business in every jurisdiction in which the failure to so qualify would reasonably be expected to have a material adverse effect on the financial condition, operating results or assets of the Company. The Company possesses all
requisite power and authority necessary to carry out the transactions contemplated by this Agreement. 

2.2.2    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 memorandum and articles of association 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 clause (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. 

2.2.3    Title to Securities. Upon issuance in accordance with, and payment pursuant to, the terms
hereof and the memorandum and articles of association of the Company, and registration in the Company’s register of members, the Shares will be duly and validly issued, fully paid and nonassessable. Upon issuance in accordance with, and payment
pursuant to, the terms hereof, and registration in the Company’s register of members, 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 (a) transfer
restrictions hereunder and other agreements to which the Shares may be subject, (b) transfer restrictions under federal and state securities laws, and (c) liens, claims or encumbrances imposed due to the actions of the Subscriber. 

2.2.4    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. 

  
 3 

	3.	 FORFEITURE OF SHARES. 

3.1    Partial or No Exercise of the Over-allotment Option. In the event the Over-allotment Option granted to the
representative(s) of the underwriters of the Company’s 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 750,000 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 shareholders prior to the IPO, if any) will
own an aggregate number of Shares (not including (i) Class A ordinary shares of the Company, $0.0001 par value per share (the “Class A Shares” and, together with the Shares, “Ordinary
Shares”), issuable upon exercise of any warrants or (ii) any securities purchased by Subscriber in the Company’s IPO or in the aftermarket) equal to 20% of the issued and outstanding Ordinary Shares immediately following the IPO.

 3.2    Termination of Rights as Shareholder. If any of the Shares are forfeited in accordance with this
Section 3, then after such time the Subscriber (or successor in interest), shall no longer have any rights as a holder of such Shares, and the Company shall take such action as is appropriate to cancel such Shares. 

 

	4.	 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 shareholders 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 securities in the
IPO or in the aftermarket, any Class A 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 Ordinary Shares into funds held in the
Trust Account upon the successful completion of an initial business combination. 
  

	5.	 RESTRICTIONS ON TRANSFER. 

5.1    Securities Law Restriction. 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. 

5.2    Lock-up. Subscriber acknowledges that the Shares will be subject to lock-up provisions (the “Lock-up”) contained in the Insider Letter. 

  
 4 

 5.3    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 UNITED STATES 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 LOCKUP PROVISIONS AND MAY NOT BE OFFERED, SOLD, TRANSFERRED, PLEDGED OR
OTHERWISE DISPOSED DURING THE TERM OF THE LOCKUP.” 
 5.4    Additional Shares or Substituted Securities. In
the event of the declaration of a share capitalization, the declaration of an extraordinary dividend payable in a form other than Shares, a spin-off, a share
sub-division, an adjustment in conversion ratio, a recapitalization or a similar transaction affecting the Company’s outstanding Ordinary 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 Section 5 or into which such Shares thereby become convertible shall immediately be subject to this
Section 5 and Section 3. 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 Section 5 and Section 3. 

5.5    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 prior to the
closing of the IPO (the “Registration Rights Agreement”). 
  

	6.	 OTHER AGREEMENTS. 

6.1    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. 
 6.2    Notices. All notices, statements
or other 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 electronic mail
address most recently provided to such party or such other electronic mail address as may be designated in writing by such party. Any notice or other communication so transmitted shall be deemed to have been given on the day of delivery, if
delivered personally, on the business day following receipt of written confirmation, if sent by facsimile or electronic transmission, one (1) business day after delivery to an overnight courier service or five (5) days after mailing if
sent by mail. 
 6.3    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-l 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 

  
 5 

 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. 

6.4    Modifications and Amendments. The terms and provisions of this Agreement may be modified or amended only by
written agreement executed by all parties hereto. 
 6.5    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. 
 6.6    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. 

6.7    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. 
 6.8    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 the State of New York applicable to contracts wholly performed within the borders of such state, without giving
effect to the conflict of law principles thereof. 
 6.9    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. 
 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. 
 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. 

  
 6 

 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. 
 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. 

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. 
 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
