 AGREEMENT 

1. Sale and Purchase. 
 (a) Forward
Purchase Shares. 
 (i) The Company shall issue and sell to the Purchaser, and the Purchaser shall purchase from the Company, that number
of Class A Shares (the “Forward Purchase Shares”), up to a maximum of 1,000,000 Class A Shares (the “Maximum Shares”), in the respective percentage set forth opposite such Purchaser’s name in the

	 Khosla Ventures SPAC Sponsor II LLC
	  	 	100	% 

 (ii) The number of Forward Purchase Shares to be issued and sold by the Company and purchased by the Purchaser
hereunder shall equal that number which, after payment of the aggregate Forward Purchase Price by the Purchaser, will result in gross proceeds to the Company in an aggregate amount equal to the amount of funds necessary for the Company to consummate
the initial Business Combination and pay related fees and expenses, less amounts available to the Company from the Trust Account (after payment of the deferred underwriting discount and after giving effect to any redemptions of Public Shares) and
any other financing source obtained by the Company for such purpose at or prior to the consummation of the initial Business Combination, plus any additional amounts mutually agreed by the Company and the Purchaser that may be retained by the
post-Business Combination company for working capital or other purposes, but in no event shall the number of Forward Purchase Shares purchased hereunder exceed the Maximum Shares. 

(iii) Each Forward Purchase Share will have the same terms as each Private Placement Share. The Forward Purchase Shares will be non- redeemable so long as they are held by the Purchaser or its Permitted Transferees (as defined below). If the Forward Purchase Shares are held by Persons (as defined below) other than the Purchaser or its
Permitted Transferees, the Forward Purchase Shares will have the same terms as the Public Shares. 
 (iv) The Company shall require the
Purchaser to purchase the Forward Purchase Shares by delivering notice to the Purchaser, at least five (5) Business Days before the Business Combination Closing, specifying the number of Forward Purchase Shares the Purchaser is required to
purchase, the date of the Business Combination Closing, the aggregate Forward Purchase Price and instructions for wiring the Forward Purchase Price. The closing of the sale of Forward Purchase Shares (the “Forward Closing”) shall be
held on the same date and immediately prior to the Business Combination Closing (such date being referred to as the “Forward Closing Date”). At least one (1) Business Day prior to the Forward Closing Date, the Purchaser shall
deliver to the Company, to be held in escrow until the Forward Closing, the Aggregate Forward Purchase Price for the Forward Purchase Shares 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 Forward Closing on the Forward Closing Date, (A) the Forward Purchase Price shall be released from escrow 

  
 2 

 
automatically and without further action by the Company or the Purchaser, and (B) upon such release, the Company shall issue the Forward Purchase Shares 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 Forward Closing shall not occur and the Company shall promptly (but not later than one (1) Business
Day thereafter) return the Forward Purchase Price to the Purchaser. For 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) Legends.
Each book entry for the Forward Purchase Shares shall contain a notation, and each certificate (if any) evidencing the Forward Purchase Shares shall be stamped or otherwise imprinted with a legend, in substantially the following form: 

“THE SECURITIES REPRESENTED HEREBY HAVE NOT BEEN REGISTERED UNDER THE 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. THE SALE, PLEDGE, HYPOTHECATION, OR TRANSFER OF THE SECURITIES REPRESENTED HEREBY ARE SUBJECT TO THE TERMS AND CONDITIONS OF A CERTAIN FORWARD PURCHASE
AGREEMENT BY AND AMONG THE HOLDER AND THE COMPANY. COPIES OF SUCH AGREEMENT MAY BE OBTAINED UPON WRITTEN REQUEST TO THE SECRETARY OF THE COMPANY.” 

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 its formation 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 against the Purchaser in accordance with its terms, except (i) as limited by applicable bankruptcy, insolvency, reorganization, moratorium,
fraudulent conveyance and any other laws of general application affecting enforcement of creditors’ rights generally, (ii) as limited by laws relating to the availability of specific performance, injunctive relief or other equitable
remedies, or (iii) to the extent the indemnification provisions contained in the Registration Rights (as defined below) 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 their 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, 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 Shares 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 in violation of any state or federal securities laws, 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 Shares. 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 Shares, 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 Shares to the Purchaser has not
been, and will not be, registered under the Securities Act of 1933, as amended (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 Shares 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 Shares 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 Shares for resale, except as provided herein (the “Registration Rights”). The
Purchaser further acknowledges that if an exemption from registration 

  
 4 

 
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 Shares, 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 filed the Registration Statement for its
proposed IPO. The Purchaser understands that the offering of the Forward Purchase Shares 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.

 (h) No Public Market. The Purchaser understands that no public market now exists for the Forward Purchase Shares, and that the
Company has made no assurances that a public market will ever exist for the Forward Purchase Shares. 
 (i) High Degree of Risk. The
Purchaser understands that its agreement to purchase the Forward Purchase Shares 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) engaged in any general solicitation, or (ii) published any advertisement in connection with the offer and sale of the Forward Purchase
Shares. 
 (l) Residence. The Purchaser’s principal place of business is the office or offices located at the address of the
Purchaser set forth on the signature page hereof. 
 (m) Adequacy of Financing. At the time of the Forward Closing, the Purchaser will
have available to it sufficient funds to satisfy its obligations under this Agreement. 
 (n) Affiliation of Certain FINRA Members.
The Purchaser is neither associated nor affiliated with Goldman Sachs & Co. LLC (“Goldman Sachs”), Citigroup Global Markets Inc. (“Citi”) 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, neither 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 with respect to the Purchaser
and this offering, and the Purchaser Parties disclaim any such representation or warranty. Except for the specific representations and warranties expressly made by the Company in Section 3 of this Agreement and in any certificate or agreement

 4. Registration Rights; Transfer 

(a) Registration. The Company agrees that it will use its commercially reasonable efforts to file with the SEC (at the Company’s
sole cost and expense), within thirty (30) calendar days after the Business Combination Closing, a registration statement (the “Forward Registration Statement”) registering the resale of the Forward Purchase Shares
(collectively, the “Registrable Securities”), and the Company shall use its commercially reasonable efforts to have the Forward Registration Statement declared effective as soon as practicable after the filing thereof; provided,
however, that the Company’s obligations to include the Registrable Securities in the Forward Registration Statement are contingent upon the Purchaser furnishing in writing to the Company such information regarding the Purchaser, the securities
of the Company held by the Purchaser and the intended method of disposition of the Registrable Securities as shall be reasonably requested by the Company to effect the registration of the Registrable Securities, and shall execute such documents in
connection with such registration as the Company may reasonably request that are customary of a selling stockholder in similar situations. 

(b) Indemnification. 
 (i)
The Company shall, notwithstanding any termination of this Agreement, indemnify, defend and hold harmless the Purchaser (to the extent a seller under the Forward Registration Statement), the officers, directors, agents, partners, members, managers,
stockholders, affiliates, employees and investment advisers of the Purchaser, each person who controls the Purchaser (within the meaning of Section 15 of the Securities Act or Section 20 of the Securities Exchange Act of 1934, as amended
(the “Exchange Act”)), and the officers, directors, partners, members, managers, stockholders, agents, affiliates, employees and investment advisers of each such controlling person, to the fullest extent permitted by applicable law,
from and against any and all losses, claims, damages, liabilities, costs (including, without limitation, reasonable costs of preparation and investigation and reasonable attorneys’ fees) and expenses (collectively, “Losses”),
as incurred, that arise out of or are based upon (A) any untrue or alleged untrue statement of a material fact contained in the Forward Registration Statement, any prospectus included in the Forward Registration Statement or any form of
prospectus or in any amendment or supplement thereto or in any preliminary prospectus, or arising out of or relating to any omission or alleged omission to state a material fact required to be stated therein or necessary to make the statements
therein (in the case of any prospectus or form of prospectus or supplement thereto, in light of the circumstances under which they were made) not misleading, or (B) any violation or alleged violation by the Company of the Securities Act, the
Exchange Act or any state securities law or any rule or regulation thereunder, in connection with the performance of its obligations under this Section 4, except to the extent, but only to the extent that such untrue statements, alleged untrue
statements, omissions or alleged omissions are based solely upon information regarding the Purchaser furnished in writing to the Company by the Purchaser expressly for use therein. The Company shall notify the Purchaser promptly of the institution,
threat or assertion of any proceeding arising from or in connection with the transactions contemplated by this Section 4 of which the Company is aware. Such indemnity shall remain in full force and effect regardless of any investigation made by
or on behalf of an indemnified party and shall survive the transfer of the Registrable Securities by the Company. 
 (ii) The Purchaser
shall, severally and not jointly with any other selling stockholder named in the Forward Registration Statement, indemnify and hold harmless the Company, its directors, officers, agents and employees, each person who controls the Company (within the
meaning of Section 15 of the Securities Act and Section 20 of the Exchange Act), and the directors, officers, agents or employees of such controlling persons, to the fullest extent 

  
 8 

 
permitted by applicable law, from and against all Losses, as incurred, arising out of or that are based upon any untrue or alleged untrue statement of a material fact contained in the Forward
Registration Statement, any prospectus included in the Forward Registration Statement, or any form of prospectus, or in any amendment or supplement thereto or in any preliminary prospectus, or arising out of or relating to any omission or alleged
omission of a material fact required to be stated therein or necessary to make the statements therein (in the case of any prospectus, or any form of prospectus or supplement thereto, in light of the circumstances under which they were made) not
misleading to the extent, but only to the extent that such untrue statements or omissions are based solely upon information regarding the Purchaser furnished in writing to the Company by the Purchaser expressly for use therein. In no event shall the
liability of the Purchaser be greater in amount than the dollar amount of the net proceeds received by the Purchaser upon the sale of the Registrable Securities giving rise to such indemnification obligation. 

(c) Transfer. This Agreement and all of the Purchaser’s rights and obligations hereunder (including the Purchaser’s obligation
to purchase the Forward Purchase Shares) may be transferred or assigned, at any time and from time to time, in whole or in part, to one or more third parties (each such transferee, a “Transferee”). Upon any such assignment: 

(i) the applicable Transferee shall execute a signature page to this Agreement, substantially in the form of the Purchaser’s signature
page hereto (the “Joinder Agreement”), which shall reflect the number of Forward Purchase Shares and Forward Purchase Warrants to be purchased by such Transferee (the “Transferee Securities”), and, upon such
execution, such Transferee shall have all the same rights and obligations of the Purchaser hereunder with respect to the Transferee Securities, and references herein to the “Purchaser” shall be deemed to refer to and include any
such Transferee with respect to such Transferee and to its Transferee Securities; provided, that any representations, warranties, covenants and agreements of the Purchaser and any such Transferee shall be several and not joint and shall be made as
to the Purchaser or any such Transferee, as applicable, as to itself only; and 
 (ii) upon a Transferee’s execution and delivery of a
Joinder Agreement, the number of Forward Purchase Shares to be purchased by the Purchaser hereunder shall be reduced by the total number of Forward Purchase Shares to be purchased by the applicable Transferee pursuant to the applicable Joinder
Agreement, which reduction shall be evidenced by the Purchaser and the Company amending Schedule A to this Agreement to reflect each transfer and updating the “Number of Forward Purchase Shares” and “Aggregate Purchase Price for
Forward Purchase Shares” on the Purchaser’s signature page hereto to reflect such reduced number of Forward Purchase Shares, and the Purchaser shall be fully and unconditionally released from its obligation to purchase such Transferee
Securities hereunder. For the avoidance of doubt, this Agreement need not be amended and restated in its entirety, but only Schedule A and the Purchaser’s signature page hereto need be so amended and updated and executed by each of the
Purchaser and the Company upon the occurrence of any such transfer of Transferee Securities.

Transfer (as defined below) any Forward Purchase Shares until the earlier of (i) one year after the Business Combination Closing or (ii) the date following the Business Combination Closing on which the Company completes a liquidation,
merger, capital stock exchange, reorganization or other similar transaction that results in all of the Company’s stockholders having the right to exchange their common stock for cash, securities or other property. Notwithstanding the foregoing,
if, subsequent to the initial Business Combination, the last sale price of the Class A Shares equals or exceeds $12.00 per share (as adjusted for stock splits, stock dividends, reorganizations, recapitalizations and the like) for any 20 trading

of any of the Company’s officers or directors, any members of the Purchaser, or any affiliates of the Purchaser; (B) in the case of an individual, by gift to a member of the individual’s immediate family, to a trust, the beneficiary
of which is a member of individual’s immediate family or an affiliate of such person, or to a charitable organization; (C) in the case of an individual, by virtue of laws of descent and distribution upon death of the individual;

distribution to limited partners, members or stockholders of the Purchaser; (I) to the Purchaser’s affiliates, to any investment fund or other entity controlled or managed by the Purchaser or any of their affiliates, or to any investment

(M) pursuant to an order of a court or regulatory agency; provided, however, that in the case of clauses (A) through (E) and (H) through (L), these Permitted Transferees must enter into a written agreement agreeing to be bound by
these transfer restrictions. For purposes of this Section, “Transfer” shall mean the (x) sale or assignment of, offer to sell, contract or agreement to sell, hypothecation, pledge, grant of any option to purchase or otherwise
dispose of or agreement to dispose of, directly or indirectly, or establishment or increase of a put equivalent position or liquidation with respect to or decrease of a call equivalent position (within the meaning of Section 16 of the Exchange
Act, and the rules and regulations of the SEC promulgated thereunder) with respect to, any of the Forward Purchase Shares (excluding any pledges in the ordinary course of business for bona fide financing purposes or as part of prime brokerage
arrangements), (y) entry into any swap or other arrangement that transfers to another, in whole or in part, any of the economic consequences of ownership of any of the Forward Purchase Shares, whether any such transaction is to be settled by

 (b) Trust Account. 

(i) The Purchaser hereby acknowledges that it is aware that the Company will establish the Trust Account for the benefit of its public
stockholders upon the IPO Closing. The Purchaser, for itself and its affiliates, hereby agrees that it has no right, title, interest or claim of any kind in or to any monies held in the Trust Account, or any other asset of the Company as a result of
any liquidation of the Company, except for redemption and liquidation rights, if any, the Purchaser may have in respect of any Public Shares held by it. 

(ii) The Purchaser hereby agrees that it shall have no right of set-off or any right, title, interest

initial Business Combination within 24 months from the IPO Closing (or such later date as has been approved by an amendment to the Charter) or in the context of a tender offer made by the Company to purchase Class A Shares, it being understood
that the Purchaser shall be entitled to redemption and liquidation rights with respect to any Public Shares held by it.

on the Purchaser or its ability to consummate the transactions contemplated by this Agreement;

satisfied and complied in all material respects with the covenants, agreements and conditions required by this Agreement to be performed, satisfied or complied with by the Purchaser at or prior to the Forward Closing; and

the Purchaser or the Company and their respective directors, officers, employees, partners, managers, members, or stockholders and all rights and obligations of each party shall cease; provided, however, that nothing contained in this Section 8
shall relieve either party from liabilities or damages arising out of any fraud or willful breach by such party of any of its representations, warranties, covenants or agreements contained in this Agreement.

may assign either this Agreement or any of its rights, interests, or obligations hereunder without the prior written approval of the other party. 

(g) Counterparts. This Agreement may be executed in two or more counterparts, each of which will be deemed an original but all of which
together will constitute one and the same instrument. 
 (h) Headings. The section headings contained in this Agreement are inserted
for convenience only and will not affect in any way the meaning or interpretation of this Agreement. 
 (i) Governing Law. This
Agreement, the entire relationship of the parties hereto, and any litigation between the parties (whether grounded in contract, tort, statute, law or equity) shall be governed by, construed in accordance with, and interpreted pursuant to the laws of
the State of New York, without giving effect to its choice of laws principles. 
 (j) Jurisdiction. The parties (i) hereby
irrevocably and unconditionally submit to the jurisdiction of the state courts of New York and to the jurisdiction of the United States District Court for the Southern District of New York for the purpose of any suit, action or other proceeding
arising out of or based upon this Agreement, (ii) agree not to commence any suit, action or other proceeding arising out of or based upon this Agreement except in state courts of New York or the United States District Court for the Southern

(m) Severability. The provisions of this Agreement will be deemed severable and the invalidity or unenforceability of any provision will

to be enforceable in accordance with its terms, the parties hereto agree that the governmental authority, arbitrator, or mediator making such determination will have the power to modify the provision in a manner consistent with its objectives such
that it is enforceable, and/or to delete specific words or phrases, and in its reduced form, such provision will then be enforceable and will be enforced. 

  
 15 

 (n) Expenses. Each of the Company and the Purchaser will bear its own costs and

counsel and accountants. The Company shall be responsible for the fees of its transfer agent; stamp taxes and all The Depository Trust Company fees associated with the issuance of the Forward Purchase Shares. 

(o) 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. Any reference to any federal, state, local, or foreign law will be deemed also to refer to law as amended and all rules and regulations promulgated thereunder, unless the context requires otherwise. 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. 

(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) 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 10.5 

March 23, 2021 
 Khosla Ventures Acquisition Co. II 

2128 Sand Hill Road 
 Menlo Park, California 94025 

 

	Re:	 Initial Public Offering 

Ladies and Gentlemen: 
 This letter agreement
(this “Letter Agreement”) is being delivered to you in accordance with the underwriting agreement (the “Underwriting Agreement”) entered into by and between Khosla Ventures Acquisition Co. II, a
Delaware corporation (the “Company”), and Citigroup Global Markets Inc. and Goldman Sachs & Co. LLC, as representatives (the “Representatives”) of the several underwriters named in
Schedule I thereto (the “Underwriters”), relating to an underwritten initial public offering (the “IPO”) of the Company’s shares (the “Shares”) of Class A common
stock, par value $0.0001 per share (the “Class A Common Stock”). Certain capitalized terms used herein are defined in paragraph 14 hereof. 

In order to induce the Company and the Underwriters to enter into the Underwriting Agreement and to proceed with the IPO, and in recognition
of the benefit that such IPO will confer upon the undersigned as a stockholder of the Company, and for other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, each of the undersigned (each, an
“Insider,” and collectively, the “Insiders”), hereby agrees, severally but not jointly, with the Company as follows: 

1. If the Company solicits approval of its stockholders of a Business Combination, then in connection with such proposed Business Combination,
such Insider will (i) vote all shares of Capital Stock beneficially owned by such Insider, whether acquired before, in or after the IPO, in favor of such Business Combination and (ii) not redeem any shares of Class A Common Stock
owned by such Insider in connection with such stockholder approval (although the Insiders and their respective affiliates shall be entitled to redemption and liquidation rights with respect to any Offering Shares such Insiders hold if the Company
fails to consummate a Business Combination within the time period set forth in the Certificate of Incorporation (as defined below)). If the Company seeks to consummate a proposed Business Combination by engaging in a tender offer, such Insider
agrees that such Insider will not sell or tender any shares of Class A Common Stock owned by such Insider in connection therewith. 
 2.
In the event that the Company fails to consummate a Business Combination within the time period set forth in the Company’s amended and restated certificate of incorporation, as the same may be amended from time to time (the
“Certificate of Incorporation”), such Insider will, as promptly as possible, (i) cause the Trust Account to be liquidated and the aggregate amount then held on deposit in the Trust Account, including interest earned on
the funds held in the Trust Account not previously released to pay taxes and less up to $100,000 of interest to pay dissolution expenses, distributed to the holders of Offering Shares and (ii) cause the Company to liquidate as soon as
reasonably practicable. 

 3. Such Insider hereby agrees to not propose, or vote in favor of, an amendment to the
Certificate of Incorporation prior to the consummation of a Business Combination to modify the substance or timing of the Company’s obligation to allow redemption in connection with the Company’s initial Business Combination or to redeem
100% of the Offering Shares if the Company does not complete a Business Combination within the time period set forth in the Certificate of Incorporation or with respect to any other provision relating to stockholders’ rights or pre-initial Business Combination activity unless the Company provides Public Stockholders with the opportunity to redeem their Offering Shares at a per share price, payable in cash, equal to the aggregate amount
then on deposit in the Trust Account, including interest earned on the funds held in the Trust Account (net of taxes payable and less up to $100,000 of interest to pay dissolution expenses), divided by the number of then-outstanding Offering
Shares, upon such approval of any such amendment in accordance with such Section 9.7 thereof. 
 4. Such Insider hereby waives,
with respect to any shares of Class A Common Stock held by such Insider, if any, any redemption rights such Insider may have in connection with a stockholder vote to approve an amendment to the Certificate of Incorporation to (i) modify
the substance or timing of the Company’s obligation to allow redemption in connection with the Company’s initial Business Combination or to redeem 100% of the Offering Shares if the Company has not consummated a Business Combination within
the time period set forth in the Certificate of Incorporation or (ii) with respect to any other provisions relating to stockholders’ rights or pre-initial Business Combination activity (although the
Insiders and their respective affiliates shall be entitled to redemption and liquidation rights with respect to any Offering Shares such Insiders hold if the Company fails to consummate a Business Combination within the time period set forth in the
Certificate of Incorporation). 
 5. Such Insider hereby waives any and all right, title, interest or claim of any kind in or to any
distribution of the Trust Account and any remaining net assets of the Company as a result of such liquidation with respect to the Founder Shares owned by such Insider and hereby waives any such right, title, interest or claim such Insider may have
in the future as a result of, or arising out of, any contracts or agreements with the Company and will not seek recourse against the Trust Account for any reason whatsoever. 

6. In the event of the liquidation of the Trust Account, Khosla Ventures SPAC Sponsor II LLC (the “Sponsor” (but not,
for purposes of clarification, any other stockholders, members or managers of the Sponsor, or any of the other Insiders)) agrees, jointly and severally, to indemnify and hold harmless the Company for any debts and obligations to prospective target
businesses with which the Company has entered into a written letter of intent, confidentiality or other similar agreement or business combination agreement or third parties that are owed money by the Company (other than the Company’s
independent registered public accounting firm) for services rendered or contracted for or products sold to the Company, but only to the extent necessary to ensure that such debt or obligation does not reduce the amount of funds in the Trust Account
to below (i) $10.00 per Offering Share or (ii) such lesser amount per Offering Share held in the Trust Account as of the date of the liquidation of the Trust Account due to reductions in the value of the trust assets, in each case, net of the
amount of interest earned on the property in the Trust Account which may be withdrawn to pay the Company’s taxes; provided that such indemnity shall not apply (i) if such prospective target business or third party has executed a
valid and enforceable agreement waiving any right, title, interest or claim of any kind they may have in or 

  
 2 

 
to any monies held in the Trust Account or (ii) as to any claims under the Company’s obligation to indemnify the Underwriters against certain liabilities, including liabilities under
the Securities Act of 1933, as amended (the “Securities Act”). In the event that any such executed waiver is deemed to be unenforceable against such third party, the Sponsor shall not be responsible to the extent of any
liability for such third party claims. The Sponsor shall have the right to defend against any such claim with counsel of its choice reasonably satisfactory to the Company if, within 15 days following written receipt of notice of the claim to the
Sponsor, the Sponsor notify the Company in writing that they shall undertake such defense. Such Insider acknowledges and agrees that there will be no distribution from the Trust Account with respect to any warrants, all rights of which will
terminate on the Company’s liquidation. 
 7. Except as disclosed in, or expressly contemplated by, the Registration Statement, neither
such Insider nor any affiliate of such Insider shall receive from the Company any finder’s fee, reimbursement, consulting fee, monies in respect of any repayment of a loan or other compensation prior to, or in connection with any services
rendered in order to effectuate the consummation of the Company’s initial Business Combination (regardless of the type of transaction that it is). Notwithstanding the foregoing, the undersigned and any affiliate of the undersigned shall be
entitled to reimbursement from the Company for their out-of-pocket expenses incurred in connection with identifying, investigating and consummating a Business
Combination. 
 8.          (a) Such Insider will not, without the prior written consent of
the Representatives pursuant to the Underwriting Agreement, offer, sell, contract to sell, pledge, hedge or otherwise dispose of (or enter into any transaction which is designed to, or might reasonably be expected to, result in the disposition
(whether by actual disposition or effective economic disposition due to cash settlement or otherwise) by such Insider or any affiliate of such Insider or any person in privity with such Insider or any affiliate of such Insider), directly or
indirectly, including the filing (or participation in the filing) of a registration statement with the Securities and Exchange Commission (the “Commission”) in respect of, or establish or increase a put equivalent position or
liquidate or decrease a call equivalent position within the meaning of Section 16 of the Securities Exchange Act of 1934, as amended, and the rules and regulations of the Commission promulgated thereunder (the “Exchange
Act”) with respect to, any Shares, shares of Class A Common Stock, Founder Shares, or any securities convertible into, or exercisable or exchangeable for shares of Class A Common Stock, or publicly announce an intention to
effect any such transaction (“Transfer”), for a period of 180 days after the date of the Underwriting Agreement; provided, however, the foregoing shall not apply to the forfeiture of any Founder Shares pursuant to
their terms or any Transfer of Founder Shares to current or future independent directors of the Company (as long as such current or future independent director is subject to the terms of this Letter Agreement with respect to such Founder Shares at
the time of such Transfer, and as long as, to the extent any reporting obligation under Section 16 of the Exchange Act is triggered as a result of such Transfer, any related Section 16 filing includes a practical explanation of the
Transfer). The provisions of this paragraph will not apply if the release or waiver is effected solely to permit a Transfer not for consideration and the transferee has agreed in writing to be bound by the same terms described in this Letter
Agreement to the extent and for the duration that such terms remain in effect at the time of the Transfer. 

  
 3 

 (b) Such Insider agrees that until the Company consummates a Business Combination, such
Insider’s Private Placement Shares will be subject to the transfer restrictions described in the private placement shares purchase agreement relating to such Insider’s Private Placement Shares. 

(c) Such Insider agrees that such Insider shall not Transfer any Class B Founder Shares (or shares of Class A Common Stock issuable
upon conversion thereof) until the earlier to occur of (a) one year after the completion of the initial Business Combination and (b) upon completion of the initial Business Combination, (x) if the last reported sale price of
Class A Common Stock equals or exceeds $12.00 per share (as adjusted for stock splits, stock capitalizations, reorganizations, recapitalizations and the like) for any 20 trading days within any 30-trading
day period commencing at least 150 days after the initial Business Combination or (y) the date on which the Company completes a liquidation, merger, capital stock exchange, reorganization or other similar transaction after the initial Business
Combination that results in all of the Company’s stockholders having the right to exchange their Class A common stock for cash, securities or other property (the “Class B Founder Shares Lock-up Period”). 
 (d) Such Insider agrees that such Insider shall not Transfer any
Class K Founder Shares for any reason, other than to specified permitted transferees or subsequent to the initial Business Combination in connection with a liquidation, merger, capital stock exchange, reorganization or other similar transaction
that results in all of the Company’s stockholders having the right to exchange their shares of Class A Common Stock for cash, securities or other property transfer (the “Class K Founder Shares Lock-up Period”), provided that any shares of Class A Common Stock issued upon conversion of any shares of Class K Founder Shares will not be subject to such restrictions. 

(e) The foregoing restrictions are not applicable to Transfers of the Founder Shares and shares of Class A Common Stock issued or issuable
upon the conversion of the Founder Shares and that are held by any Insider or any of their permitted transferees (that have complied with this paragraph), are permitted (a) to the Company’s officers or directors, any affiliates or family
members of any of the Company’s officers or directors, any members or partners of the Sponsor or its affiliates, any affiliates of the Sponsor, or any employees of such affiliates; (b) in the case of an individual, by gift to a member of
one of the individual’s immediate family or to a trust, the beneficiary of which is a member of the individual’s immediate family, an affiliate of such person or to a charitable organization; (c) in the case of an individual, by
virtue of laws of descent and distribution upon death of the individual; (d) in the case of an individual, pursuant to a qualified domestic relations order; (e) by private sales or transfers made in connection with the completion of a
Business Combination at prices no greater than the price at which the founder shares, private placement shares or Class A Common Stock, as applicable, were originally purchased; (f) by virtue of the limited partnership agreements or other
applicable organizational documents of the Sponsor upon dissolution of our sponsor; (g) as distributions to limited partners or members of our sponsor; (h) by virtue of the laws of the State of Delaware or of the Sponsor’s
organizational documents upon liquidation or dissolution of our sponsor; (i) to the company for no value for cancellation in connection with the completion of our initial Business Combination; (j) in the event of the Company’s
liquidation prior to the completion of the initial Business Combination; or (k) in the event of the Company’s completion of a liquidation, merger, capital stock exchange, reorganization or other similar transaction which results in all of
the Company’s stockholders having the right to exchange their Class A Common Stock for cash, securities or other property subsequent to the Company’s completion of the initial Business Combination; provided, however, that in the case
of clauses (a) through (h), or with the prior written consent of the company, these permitted transferees must enter into a written agreement agreeing to be bound by these transfer restrictions and the other restrictions contained in this
Agreement. 

  
 4 

 (f) After the IPO, to the extent the Sponsor contributes additional capital to fund the
working capital of the Company, such Insider (other than the Sponsor) will fund a pro rata amount based on such Insider’s ownership of Private Placement Shares. 

9. In order to minimize potential conflicts of interest that may arise from multiple corporate affiliations, such Insider hereby agrees that
until the earlier of the Company’s initial Business Combination and liquidation, the undersigned shall present to the Company for its consideration, prior to presentation to any other entity, any target business that has a fair market value of
at least 80% of the assets held in the Trust Account (excluding deferred underwriting commissions and taxes payable on the income accrued on the Trust Account), subject to any pre-existing fiduciary or
contractual obligations such Insider might have. 
 10. Such Insider’s biographical information previously furnished to the Company and
the Representatives (including any such information included in the Registration Statement) is true and accurate in all respects, does not omit any material information with respect to such Insider’s background and contains all of the
