 RE: Securities
Subscription Agreement 
 Ladies and Gentlemen: 

This agreement (the “Agreement”) is entered into on January 29, 2021 by and between Khosla Ventures SPAC Sponsor
II LLC, a Delaware limited liability company (the “Subscriber” or “you”), and Khosla Ventures Acquisition Co. II, 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 5,000,000 shares of Class B common stock, $0.0001 par value per share (the “Class B
Shares”) and 5,000,000 shares of Class K common stock, $0.0001 par value per share (the “Class K Shares” and with the Class B Shares, the “Shares”). 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. Each share of Class K Common Stock and Class
B Common Stock that remains issued and outstanding as of the tenth (10th) anniversary of the Company’s initial merger, capital stock exchange, asset acquisition, stock purchase, reorganization or similar business combination with one or more
businesses shall be forfeited for no consideration. 
 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. 

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.” 
 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. 

  
 5 













 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.

reasonably be necessary to carry out the intent of this Agreement.

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. 

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

 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. 

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. 

ARTICLE VII. 
 VOTING AND TENDER OF
SHARES 
 Subscriber agrees to vote the Shares in favor of an initial business combination that the Company negotiates and submits for
approval to the 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.
