WHEREAS, the Board and the stockholders of the Company have approved and adopted a Fourth Amended and Restated Certificate of Incorporation of the Company, as may be amended, modified or restated from time to time (the “Restated Certificate of Incorporation”), which, among other things provides for two classes of Common Stock of the Company, Class A Common Stock, par value $0.0001 per share (“Class A Common Stock”), entitling holders to one vote per share, and Class B Common Stock, par value $0.0001 per share (“Class B Common Stock”), (i) initially entitling holders to 1 vote per share, and (ii) upon the Public Offering Date (as defined in the Restated Certificate of Incorporation), entitling holders to 10 votes per share.

WHEREAS, the Founder holds awards of stock options that (after giving effect to the Dual-Class Structure) are exercisable for shares of Class A Common Stock as set forth in Exhibit A (each, a “Founder Equity Award” and collectively, the “Founder Equity Awards”), and each Founder Equity Award has been granted under the Company’s 2019 Stock Option Plan, as amended (the “Plan”), and is memorialized in an equity award agreement (collectively for all Outstanding Awards, the “Equity Documents”).

WHEREAS, in connection with the implementation of the Dual-Class Structure, the Board has approved the grant to the Founder of the right to require the Company to exchange Put Eligible Shares (as defined blow) for shares of Class B Common Stock, subject to the terms and conditions set forth in this Agreement.

NOW, THEREFORE, in consideration of the foregoing recitals and the mutual promises, representations and covenants set forth herein, and for other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged and accepted, the parties hereto agree as follows:

ARTICLE I.

PUT RIGHT AND EXCHANGE AND ISSUANCE OF CLASS B COMMON STOCK

1.1 Grant of Put Right. Subject to the terms and provisions of this Agreement, the Company hereby irrevocably grants to each Founder the right (the “Put Right”) to require the Company to exchange any shares of Class A Common Stock that such Founder acquires following the date hereof as a result of the exercise, issuance and/or settlement of the Founder Equity Awards (the “Put Eligible Shares”) for either, at such Founder’s election, (a) an equivalent number of shares of Class B Common Stock or (b) if the fair market value of the Class B Common Stock is greater than the fair market value of the Class A Common Stock, measured on the applicable Exchange Date (as defined below) (which shall be determined by a majority of the disinterested members of the Board), a number of shares of Class B Common Stock having equivalent value as the Put Eligible Shares, subject to the terms and conditions set forth in this Agreement (an “Exchange”). Each Founder shall be entitled to exercise the Put Right any number of times and the Put Right shall be exercisable for any or all of the outstanding Put Eligible Shares at the time such Founder issues a Put Right Notice (as defined below).

1.2 Exercise of Put Right.

(a) The Put Right will be exercisable by the Founder by submitting a completed and fully executed notice in the form attached hereto as Exhibit B (a “Put Right Notice” and the Put Eligible Shares subject to a Put Right Notice, the “Put Exercised Shares”) to the Company on or prior to the applicable Expiration Time (as defined below).

(b) Failure to deliver a Put Right Notice prior to the Expiration Time will constitute an irrevocable waiver of the Put Right with respect to the applicable Put Eligible Shares.

(c) The Founder will have no Put Right pursuant to this Agreement with respect to any share of Class A Common Stock that is acquired by the Founderfollowing the date hereof, other than shares of Class A Common Stock that the Founder acquire as a result of the exercise, issuance and/or settlement of the Founder Equity Awards.

1.3 Exchange Conditions. As conditions precedent to the effectiveness of an Exchange pursuant to a Put Right Notice (collectively, the “Exchange Conditions”):

(a) a majority of the disinterested members of the Board shall have determined whether, as of the applicable Exchange Date (as defined below), there will be any difference between the fair market values of the Class A Common Stock and Class B Common Stock;

(b) the Company shall have determined the amount of wages or other income, if any, that shall be recognized by the Founder for U.S. federal and state income tax purposes on account of such exercise of the Put Right and the related Exchange;

(c) the Founder and the Company shall have made any required filings of the notification and report form for certain mergers and acquisitions under the Hart-Scott-Rodino Antitrust Improvements Act of 1976 (the “HSR Act”), and any applicable waiting periods shall have expired; and

(d) the number of shares of Class B Common Stock authorized and available for issuance under the Restated Certificate of Incorporation shall be equal to or greater than the applicable number of Exchange Shares (as defined below).

1.4 Exchange of Shares. With respect to each Put Right Notice, on the tenth business day (as defined below), or such later date as agreed to by the Founder and the Company (as applicable, the “Exchange Date”), after both (a) the Company’s receipt of such Put Right Notice, properly executed by the Founder, and (b) the satisfaction of the Exchange Conditions, the Company will complete the Exchange by issuing to the Founder the applicable number of shares of Class B Common Stock to be issued as a result of the Exchange pursuant to Section 1.1 (the “Exchange Shares”), out of shares authorized and available for issuance under the Restated Certificate of Incorporation, in exchange for the applicable Put Exercised Shares. Upon the effectiveness of such Exchange, the Company will deliver to the Founder an electronic stock certificate via the Shareworks platform or book entry via the Company’s transfer agent to evidence that the Exchange Shares have been duly issued to the Founder in exchange for the Put Exercised Shares. For purposes of this Agreement, “business day” means a weekday on which banks are open for general banking business in New York, New York.

1.5 Tax Withholding. Prior to each Exchange Date, if the Company has determined that any wages or other income shall be recognized by the Founder for U.S. federal and state income tax purposes on account of the applicable Exchange, the Founder must pay or make provisions satisfactory to the Company for the payment of the foreign, federal, state and local income tax, social insurance, payroll tax,

fringe benefits tax, payment on account withholding and other tax-related items related to such Exchange and legally applicable to the Founder, including, as applicable, obligations of the Company to withhold any of the foregoing (all the foregoing tax-related items, “Tax-Related Items”). The Company may withhold or account for Tax-Related Items by considering applicable minimum statutory withholding rates or other applicable statutory rates with respect to the Founder, including maximum applicable rates.

1.6 Rights to Put Exercised Shares Following the Exchange. Following each Exchange, the Founder will no longer have any rights as a holder of the Put Exercised Shares that were the subject of such Exchange (other than the right to receive the Exchange Shares in accordance with this Agreement). Such Put Exercised Shares will be deemed to have been cancelled by the Company in accordance with the applicable provisions hereof and shall not be retained in treasury, whether or not the certificate(s) therefor have been delivered to the Company. The Put Exercised Shares will not become available for grant and issuance in connection with other Awards (as defined in the Plan) under the Plan.

1.7 Termination of Put Right. The Put Right will terminate as follows (as applicable, the “Expiration Time”):

(a) With respect to Put Exercised Shares, upon completion of the applicable Exchange;

(b) With respect to any shares of Class A Common Stock subject to a Founder Equity Award that have not become Put Eligible Shares, the Expiration Time will be when such shares are forfeited pursuant to the applicable Equity Documents; and

(i) when the Founder sells, transfers or otherwise disposes of such Put Eligible Shares; and

To:	CoreWeave, Inc.

Attn: Chief Executive Officer

The undersigned (the “Founder”) hereby irrevocably elects to exercise the Put Right pursuant to the Equity Exchange Right Agreement dated as of September 30, 2024 (the “Agreement”), by and between CoreWeave, Inc. (the “Company”) and the Founder, to require the Company to exchange the Put Eligible Shares listed on the signature page hereto for either, at the Founder’s election (as set forth on the signature page hereto), (a) an equivalent number of shares of Class B Common Stock or (b) if the fair market value of the Class B Common Stock is greater than the fair market value of the Class A Common Stock, measured on the applicable Exchange Date (which shall be determined by a majority of the disinterested members of the Board), a number of shares of Class B Common Stock having equivalent value as the Put Eligible Shares, subject to the terms of this notice (this “Notice”) and the Agreement (the “Exchange”). Capitalized terms not otherwise defined in this Notice will have the meaning ascribed to them in the Agreement.

By executing this Notice, the Founder hereby represents and warrants to the Company as follows:

1. Acknowledgements. The Founder acknowledges and affirms that the representations and warranties set forth in Article II of the Agreement as of the date of this Notice are true and correct, and agrees to the covenants set forth in Sections 4.1 through 4.5 of the Agreement to the extent applicable as of the date hereof.

2. Legends. It is understood that any certificate or book entry position representing the Exchange Shares and any securities issued in respect thereof or exchange therefor, will bear legends in substantially the following form (in addition to any legend required under applicable state securities laws or agreements to which the Founder is a party):

“THE SECURITIES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED, OR UNDER THE SECURITIES LAWS OF CERTAIN STATES. NO TRANSFER MAY BE EFFECTED WITHOUT AN EFFECTIVE REGISTRATION STATEMENT RELATED THERETO OR AN OPINION OF COUNSEL THAT SUCH REGISTRATION IS NOT REQUIRED UNDER THE SECURITIES ACT OF 1933, AS AMENDED.”

3. Restricted Securities; Rule 144. Except as otherwise permitted by applicable law, the Founder understands that the Exchange Shares issued to the Founder in the Exchange pursuant to this Notice will be characterized as “restricted securities” under the Securities Act of 1933, as amended (the “Act”), because such shares are being acquired from the Company in a transaction not involving a public offering and in exchange for shares acquired from the Company in a transaction not involving a public offering, and that under the Act and the rules and regulations promulgated thereunder the Exchange Shares may be resold without registration under the Act only in certain limited circumstances, and subject to the restrictions under the Restated Certificate of Incorporation. The Founder understands and hereby acknowledges that the Exchange Shares must be held indefinitely unless subsequently registered under the Act or an exemption from such registration is otherwise available. The Founder is aware of the provisions of Rule 144 promulgated under the Act, which permit limited resales of shares purchased in a transaction not involving a public offering, subject to the satisfaction of certain conditions.

4. Tax Matters. The Founder has reviewed with his own tax advisors the federal, state, local and foreign tax consequences of the Put Right and the Exchange, the Founder Equity Awards and the potential acquisition of shares of Class A Common Stock thereunder, the potential exchange of such shares for shares of Class B Common Stock, and the transactions contemplated by this Agreement. The Founder is relying solely on such advisors and not on any statements or representations of the Company or any of its agents in connection with the transactions contemplated hereby, except for the representations and warranties of the Company expressly set forth in Article III of the Agreement.

5. Tax Withholding. The Founder acknowledges, affirms and agrees that, prior to the Exchange Date for the Exchange pursuant to this Notice, if the Company determines that any wages or other income shall be recognized by the Founder for U.S. federal and state income tax purposes on account of the Exchange, the Founder shall pay or make provisions satisfactory to the Company for the payment of the applicable Tax-Related Items.
