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

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.

(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.

(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.

15. This Letter Agreement shall be governed by and construed and enforced in accordance with the laws of the State of New York, without giving effect to conflicts of law principles that would result in the application of the substantive laws of another jurisdiction.
