WARRANT TO PURCHASE SHARES OF COMMON STOCK

This Warrant is issued to Riviera Investment Partners LLC or its assigns (the “Holder”) by DoorDash, Inc., a Delaware corporation (the “Company”).

1. Purchase of Shares.

(a) Number of Shares. Subject to the terms and conditions set forth herein, the Holder is entitled, upon surrender of this Warrant at the principal office of the Company (or at such other place as the Company shall notify the Holder in writing), to purchase from the Company up to 21,066 fully paid and nonassessable shares of the Company’s Common Stock, par value $0.00001 per share (the “Common Stock”).

(b) Exercise Price. The exercise price for the shares of Common Stock issuable pursuant to this Section 1 (the “Shares”) shall be $7.46 per share (the “Exercise Price”). The Shares and the Exercise Price shall be subject to adjustment pursuant to Section 7 hereof.

2. Exercise Period. This Warrant shall be exercisable, in whole or in part, during the term commencing on December 22, 2015 and ending at 5:00 p.m. Pacific time on October 17, 2025 (the “Exercise Period”); provided, however, that this Warrant shall no longer be exercisable and become null and void upon (a) the consummation of the Company’s sale of its Common Stock or other securities in the Company’s first underwritten public offering pursuant to an effective registration statement under the Securities Act of 1933, as amended (other than a registration statement relating either to sale of securities to employees of the Company pursuant to its stock option, stock purchase or similar plan or a SEC Rule 145 transaction) (an “Initial Public Offering”) and (b) the consummation of a Liquidation Event, as such term is defined in the Company’s current Restated Certificate of Incorporation on file with the Secretary of State of the State of Delaware. For purposes of this Warrant, any of the transactions described in subsection (b) shall be referred to herein as a “Corporate Transaction”. In the event of an Initial Public Offering or Corporate Transaction, the Company shall notify the Holder at least ten (10) days prior to the consummation of such Initial Public Offering or Corporate Transaction.

3. Method of Exercise.

(a) While this Warrant remains outstanding and exercisable in accordance with Section 2 above, the Holder may exercise, in whole or in part, the purchase rights evidenced hereby. Such exercise shall be effected by:

(i) the surrender of the Warrant, together with a duly executed copy of the Notice of Exercise attached hereto, to the Secretary of the Company at its principal office (or at such other place as the Company shall notify the Holder in writing); and

(ii) the payment to the Company of an amount equal to the aggregate Exercise Price for the number of Shares being purchased.

(b) Each exercise of this Warrant shall be deemed to have been effected immediately prior to the close of business on the day on which this Warrant is surrendered to the Company as provided in Section 3(a) above. At such time, the person or persons in whose name or names any certificate for the Shares shall be issuable upon such exercise as provided in Section 3(c) below shall be deemed to have become the holder or holders of record of the Shares represented by such certificate.

(c) As soon as practicable after the exercise of this Warrant in whole or in part the Company at its expense will cause to be issued in the name of, and delivered to, the Holder, or as such Holder (upon payment by such Holder of any applicable transfer taxes) may direct:

(i) a certificate or certificates for the number of Shares to which such Holder shall be entitled, and

(ii) in case such exercise is in part only, a new warrant or warrants (dated the date hereof) of like tenor, calling in the aggregate on the face or faces thereof for the number of Shares equal to the number of such Shares described in this Warrant minus the number of such Shares purchased by the Holder upon all exercises made in accordance with Section 3(a) above or Section 4 below.

4. Net Exercise. In lieu of exercising this Warrant for cash, the Holder may elect to receive shares equal to the value of this Warrant (or the portion thereof being exercised) by surrender of this Warrant at the principal office of the Company together with notice of such election (a “Net Exercise”). A Holder who Net Exercises shall have the rights described in Sections 3(b) and 3(c) hereof, and the Company shall issue to such Holder a number of Shares computed using the following formula:

Where

For purposes of this Section 4, the fair market value of a Share shall mean the average of the closing prices of the Shares (or equivalent shares of Common Stock underlying this Warrant) quoted on any exchange or electronic securities market on which the Shares (or equivalent shares of Common Stock underlying the Warrant) are listed, as published in The Wall Street Journal for the thirty (30) trading days prior to the date of determination of fair market value (or such shorter period of time during which such Shares were traded on such exchange). In the event that this Warrant is exercised pursuant to this Section 4 in connection with the Initial Public Offering, the fair market value per Share shall be the per share offering price to the public of the Initial Public Offering. If the Shares are not traded on an exchange or an electronic securities market, the fair market value shall be the price per Share that the Company could obtain from a willing buyer for Shares sold by the Company from authorized but unissued Shares, as such prices shall be determined in good faith by the Company’s Board of Directors.

5. Representations and Warranties of the Holder. In connection with the transactions provided for herein, the Holder hereby represents and warrants to the Company that:

(a) Authorization. Holder represents that it has full power and authority to enter into this Warrant. This Warrant constitutes the Holder’s valid and legally binding obligation, enforceable in accordance with its terms, except as may be limited by (i) applicable bankruptcy, insolvency, reorganization, or similar laws relating to or affecting the enforcement of creditors’ rights and (ii) laws relating to the availability of specific performance, injunctive relief or other equitable remedies.

(b) Purchase Entirely for Own Account. The Holder acknowledges that this Warrant is entered into by the Holder in reliance upon such Holder’s representation to the Company that the Warrant and the Shares (collectively, the “Securities”) will be acquired for investment for the Holder’s own account, not as a nominee or agent, and not with a view to the resale or distribution of any part thereof, and that the Holder has no present intention of selling, granting any participation in or otherwise distributing the same. By acknowledging this Warrant, the Holder further represents that the Holder does not 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 the Securities.

(c) Disclosure of Information. The Holder acknowledges that it has received all the information it considers necessary or appropriate for deciding whether to acquire the Securities. The Holder further represents that it has had an opportunity to ask questions and receive answers from the Company regarding the terms and conditions of the offering of the Securities.

(d) Investment Experience. The Holder is an investor in securities of companies in the development stage and acknowledges that it is able to fend for itself, can bear the economic risk of its investment, and has such knowledge and experience in financial or business matters that it is capable of evaluating the merits and risks of the investment in the Securities. If other than an individual, the Holder also represents it has not been organized solely for the purpose of acquiring the Securities.

(e) Accredited Investor. The Holder is an “accredited investor” within the meaning of Rule 501 of Regulation D, as presently in effect, as promulgated by the Securities and Exchange Commission (the “SEC”) under the Act.

(f) Restricted Securities. The Holder understands that the Securities are characterized as “restricted securities” under the federal securities laws inasmuch as they are being acquired from the Company in a transaction not involving a public offering and that under such laws and applicable regulations such securities may be resold without registration under the Act, only in certain limited circumstances. In this connection, the Holder represents that it is familiar with Rule 144, as presently in effect, as promulgated by the SEC under the Act (“Rule 144”), and understands the resale limitations imposed thereby and by the Act.

(g) Further Limitations on Disposition. Without in any way limiting the representations set forth above, the Holder further agrees not to make any disposition of all or any portion of the Securities unless and until the transferee has agreed in writing for the benefit of the Company to be bound by the terms of this Warrant, including, without limitation, this Section 5, Section 20, and:

(i) there is then in effect a registration statement under the Act covering such proposed disposition and such disposition is made in accordance with such registration statement; or

(ii) the Holder shall have notified the Company of the proposed disposition and shall have furnished the Company with a detailed statement of the circumstances surrounding the proposed disposition, and if reasonably requested by the Company, the Holder shall have furnished the Company with an opinion of counsel, reasonably satisfactory to the Company, that such disposition will not require registration of such shares under the Act. It is agreed that the Company will not require opinions of counsel for transactions made pursuant to Rule 144 except in extraordinary circumstances.

(h) Legends. It is understood that the Securities may bear the following legend:

“THESE SECURITIES HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED. THEY MAY NOT BE SOLD, OFFERED FOR SALE, PLEDGED, HYPOTHECATED, OR OTHERWISE TRANSFERRED EXCEPT PURSUANT TO AN EFFECTIVE REGISTRATION STATEMENT UNDER THE SECURITIES ACT OF 1933, AS AMENDED, OR AN OPINION OF COUNSEL SATISFACTORY TO THE COMPANY THAT REGISTRATION IS NOT REQUIRED UNDER SUCH ACT OR UNLESS SOLD PURSUANT TO RULE 144 UNDER SUCH ACT.”

6. State Commissioners of Corporations. THE SALE OF THE SECURITIES WHICH ARE THE SUBJECT OF THIS WARRANT HAS NOT BEEN QUALIFIED WITH THE COMMISSIONER OF CORPORATIONS OF THE STATE OF CALIFORNIA AND THE ISSUANCE OF SUCH SECURITIES OR THE PAYMENT OR RECEIPT OF ANY PART OF THE CONSIDERATION FOR SUCH SECURITIES PRIOR TO SUCH QUALIFICATION IS UNLAWFUL, UNLESS THE SALE OF SECURITIES IS EXEMPT FROM QUALIFICATION BY SECTION 25100, 25102 OR 25105 OF THE CALIFORNIA CORPORATIONS CODE. THE RIGHTS OF ALL PARTIES TO THIS WARRANT ARE EXPRESSLY CONDITIONED UPON SUCH QUALIFICATION BEING OBTAINED, UNLESS THE SALE IS SO EXEMPT.

7. Adjustment of Exercise Price and Number of Shares. The number and kind of Shares purchasable upon exercise of this Warrant and the Exercise Price shall be subject to adjustment from time to time as follows:

(a) Subdivisions, Combinations and Other Issuances. If the Company shall at any time after the issuance but prior to the expiration of this Warrant subdivide its Common Stock, by split-up or otherwise, or combine its Common Stock, or issue additional shares of its Preferred Stock or Common Stock as a dividend with respect to any shares of its Common Stock, the number of Shares issuable on the exercise of this Warrant shall forthwith be proportionately increased in the case of a subdivision or stock dividend, or proportionately decreased in the case of a combination. Appropriate adjustments shall also be made to the Exercise Price payable per share, but the aggregate Exercise Price payable for the total number of Shares purchasable under this Warrant (as adjusted) shall remain the same. Any adjustment under this Section 7(a) shall become effective at the close of business on the date the subdivision or combination becomes effective, or as of the record date of such dividend, or in the event that no record date is fixed, upon the making of such dividend.

(b) Reclassification, Reorganization and Consolidation. In case of any reclassification, capital reorganization or change in the capital stock of the Company (other than as a result of a subdivision, combination or stock dividend provided for in Section 7(a) above), then, as a condition of such reclassification, reorganization or change, lawful provision shall be made, and duly executed documents evidencing the same from the Company or its successor shall be delivered to the Holder, so that the Holder shall have the right at any time prior to the expiration of this Warrant to purchase, at a total price equal to that payable upon the exercise of this Warrant, the kind and amount of shares of stock and other securities or property receivable in connection with such reclassification, reorganization or change by a holder of the same number and type of securities as were purchasable as Shares by the Holder immediately prior to such reclassification, reorganization or change. In any such case appropriate provisions shall be made with respect to the rights and interest of the Holder so that the provisions hereof shall thereafter be applicable with respect to any shares of stock or other securities or property deliverable upon exercise hereof, and appropriate adjustments shall be made to the Exercise Price per Share payable hereunder, provided the aggregate Exercise Price shall remain the same.

(c) Notice of Adjustment. When any adjustment is required to be made in the number or kind of shares purchasable upon exercise of the Warrant, or in the Exercise Price, the Company shall promptly notify the Holder of such event and of the number of Shares or other securities or property thereafter purchasable upon exercise of this Warrant.

8. No Fractional Shares or Scrip. No fractional shares or scrip representing fractional shares shall be issued upon the exercise of this Warrant, but in lieu of such fractional shares the Company shall make a cash payment therefor on the basis of the Exercise Price then in effect.

9. No Stockholder Rights. Prior to exercise of this Warrant, the Holder shall not be entitled to any rights of a stockholder with respect to the Shares, including (without limitation) the right to vote such Shares, receive dividends or other distributions thereon, exercise preemptive rights or be notified of stockholder meetings, and, except as otherwise provided in this Warrant, such Holder shall not be entitled to any stockholder notice or other communication concerning the business or affairs of the Company.

10. Right of First Refusal.

(a) Right of First Refusal. In the event that the Holder proposes to sell, pledge or otherwise transfer to a third party any Shares, or any interest in the Shares, the Company shall have the right of first refusal with respect to all (and not less than all) of such Shares (the “Right of First Refusal”). If the Holder desires to transfer the Shares, the Holder shall give a written transfer notice to the Company describing fully the proposed transfer, including the number of Shares proposed to be transferred, the proposed transfer price, the name and address of the proposed transferee and proof satisfactory to the Company that the proposed sale or transfer will not violate any applicable federal, State or foreign securities laws. The transfer notice shall be signed both by the Holder and by the proposed transferee and must constitute a binding commitment of both parties to the transfer of the Shares. The Company shall have the right to purchase all, and not less than all, of the Shares on the terms of the proposal described in the transfer notice (subject, however, to any change in such terms permitted under Subsection (b) below) by delivery of a notice of exercise of the Right of First Refusal within 30 days after the date when the transfer notice was received by the Company.

(b) Transfer of Shares. If the Company fails to exercise its Right of First Refusal within 30 days after receiving the transfer notice, the Holder may, not later than 90 days after the Company received the transfer notice, conclude a transfer of the Shares subject to the transfer notice on the terms and conditions described in the transfer notice, provided that any such sale is made in compliance with applicable federal, State and foreign securities laws and not in violation of any other contractual restrictions to which the Holder is bound. Any proposed transfer on terms and conditions different from those described in the transfer notice, as well as any subsequent proposed transfer by the Holder, shall again be subject to the Right of First Refusal and shall require compliance with the procedure described in Subsection (a) above. If the Company exercises its Right of First Refusal, the parties shall consummate the sale of the Shares on the terms set forth in the transfer notice within 60 days after the Company received the transfer notice (or within such longer period as may have been specified in the transfer notice); provided, however, that in the event the transfer notice provided that payment for the Shares was to be made in a form other than cash or cash equivalents paid at the time of transfer, the Company shall have the option of paying for the Shares with cash or cash equivalents equal to the present value of the consideration described in the transfer notice.

(c) Additional or Exchanged Securities and Property. In the event of a merger or consolidation of the Company with or into another entity, any other corporate reorganization, a stock split, the declaration of a stock dividend, the declaration of an extraordinary dividend payable in a form other than stock, a spin-off, an adjustment in conversion ratio, a recapitalization or a similar transaction affecting the Company’s outstanding securities, any securities or other property (including cash or cash equivalents) that are by reason of such transaction exchanged for, or distributed with respect to, any Shares subject to this Section 10 shall immediately be subject to the Right of First Refusal. Appropriate adjustments to reflect the exchange or distribution of such securities or property shall be made to the number and/or class of the Shares subject to this Section 10.

(d) Termination of Right of First Refusal. Any other provision of this Section 10 notwithstanding, in the event that the Common Stock is readily tradable on an established securities market when the Holder desires to transfer Shares, the Company shall have no Right of First Refusal, and the Holder shall have no obligation to comply with the procedures prescribed by Subsections (a) and (b) above.

(e) Applicability After Transfer. If the Holder transfers any Shares after the Company has failed to exercise the Right of First Refusal, then this Agreement shall apply to the transferee to the same extent as to the Holder.

(f) Assignment of Right of First Refusal. The Board of Directors may freely assign the Company’s Right of First Refusal, in whole or in part. Any person who accepts an assignment of the Right of First Refusal from the Company shall assume all of the Company’s rights and obligations under this Section 10.

11. Governing Law. This Warrant shall be governed by and construed under the laws of the State of California as applied to agreements among California residents, made and to be performed entirely within the State of California.

12. Successors and Assigns. The terms and provisions of this Warrant shall inure to the benefit of, and be binding upon, the Company and the holders hereof and their respective successors and assigns.

13. Counterparts. This Warrant may be executed in two or more counterparts, each of which shall be deemed an original, but all of which together shall constitute one and the same instrument.

14. Titles and Subtitles. The titles and subtitles used in this Warrant are used for convenience only and are not to be considered in construing or interpreting this Warrant.

15. Notices. All notices and other communications given or made pursuant hereto shall be in writing and shall be deemed effectively given: (a) upon personal delivery to the party to be notified, (b) when sent by confirmed electronic mail or facsimile if sent during normal business hours of the recipient, and if not so confirmed, then on the next business day, (c) five (5) days after having been sent by registered or certified mail, return receipt requested, postage prepaid, or (d) one (1) day after deposit with a nationally recognized overnight courier, specifying next day delivery, with written verification of receipt.

16. Finder’s Fee. Each party represents that it neither is or will be obligated for any finder’s fee or commission in connection with this transaction. The Holder agrees to indemnify and to hold harmless the Company from any liability for any commission or compensation in the nature of a finder’s fee (and the costs and expenses of defending against such liability or asserted liability) for which the Holder or any of its officers, partners, employees or representatives is responsible.

This Warrant and any other documents delivered pursuant hereto constitute the full and entire understanding and agreement between the parties with regard to the subjects hereof and thereof.

19. Severability. If any provision of this Warrant is held to be unenforceable under applicable law, such provision shall be excluded from this Warrant and the balance of the Warrant shall be interpreted as if such provision were so excluded and shall be enforceable in accordance with its terms.

20. “Market Stand-Off” Agreement. The Holder hereby agrees that it will not, without the prior written consent of the managing underwriter, during the period commencing on the date of the final prospectus relating to the Company’s Initial Public Offering and ending on the date specified by the Company and the managing underwriter (such period not to exceed one hundred eighty (180) days) (i) lend, offer, pledge, sell, contract to sell, sell any option or contract to purchase, purchase any option or contract to sell, grant any option, right or warrant to purchase, or otherwise transfer or dispose of, directly or indirectly, any shares of the Company’s capital stock acquired through the exercise of this Warrant, or (ii) enter into any swap or other arrangement that transfers to another, in whole or in part, any of the economic consequences of ownership of the

Company’s capital stock acquired through the exercise of this Warrant, whether any such transaction described in clause (i) or (ii) above is to be settled by delivery of securities, in cash or otherwise. The underwriters in connection with the Company’s Initial Public Offering are intended third party beneficiaries of this Section and shall have the right, power and authority to enforce the provisions hereof as though they were a party hereto. Holder further agrees to execute such agreements as may be reasonably requested by the underwriters in the Company’s Initial Public Offering that are consistent with this Section 20 or that are necessary to give further effect thereto.

In order to enforce the foregoing covenant, the Company may impose stop-transfer instructions with respect to shares of the Company’s capital stock acquired through the exercise of this Warrant (and the shares or securities of every other person subject to the foregoing restriction) until the end of such period. Notwithstanding the foregoing, if (i) during the last seventeen (17) days of the one hundred eighty (180)-day restricted period, the Company issues an earnings release or material news or a material event relating to the Company occurs; or (ii) prior to the expiration of the one hundred eighty (180)-day restricted period, the Company announces that it will release earnings results during the sixteen (16)-day period beginning on the last day of the one hundred eighty (180)-day period, the restrictions imposed by this Section 20 shall continue to apply until the expiration of the eighteen (18)-day period beginning on the issuance of the earnings release or the occurrence of the material news or material event.

The Holder agrees that a legend reading substantially as follows shall be placed on all certificates representing all Shares of the Holder (and the shares or securities of every other person subject to the restriction contained in this Section 20):

THE SECURITIES REPRESENTED BY THIS CERTIFICATE ARE SUBJECT TO A LOCK-UP PERIOD AFTER THE EFFECTIVE DATE OF THE ISSUER’S REGISTRATION STATEMENT FILED UNDER THE ACT, AS AMENDED, AS SET FORTH IN AN AGREEMENT BETWEEN THE COMPANY AND THE ORIGINAL HOLDER OF THESE SECURITIES, A COPY OF WHICH MAY BE OBTAINED AT THE ISSUER’S PRINCIPAL OFFICE. SUCH LOCK-UP PERIOD IS BINDING ON TRANSFEREES OF THESE SHARES.

IN WITNESS WHEREOF, the parties have executed this Warrant as of the date first written above.
