Amended & Restated Advisor Agreement James Snabe C3.ai, Inc. Confidential 1 AMENDED & RESTATED ADVISOR AGREEMENT This Amended & Restated Advisor Agreement (this “Restated Agreement”), effective as of September ___, 2020 ("Effective Date"), by and between James Snabe (“Snabe”) and C3.ai, Inc. (the “Company”) amends and restates, in its entirety, that Advisor Agreement between Snabe and the Company dated September 25, 2018 (the “Original Agreement”), which shall, upon execution of this Restated Agreement by both parties, terminate and be of no further force and effect. Snabe and the Company hereby agree as follows: 1. Services and Consideration. During the term of this Restated Agreement, Snabe will serve as a special advisor to the Company’s Chief Executive Officer and provide advice and counsel as may be requested from time to time, including by rendering the following services: attendance and participation at all regularly scheduled meetings of the Company’s Board of Directors (the “Board of Directors”), providing strategic and growth advice to the Chief Executive Officer and the executive team, providing customer and strategic relationship assistance, and otherwise consult and work with and advise Company from time to time on matters relating to Company's actual or potential business, technology and products (the “Services”). Snabe will report directly to the Company’s Chief Executive Officer in the course of performing his duties. In the event that Snabe is appointed to the Board of Directors, this Advisor agreement will terminate. As consideration in full for the Services, subject to the approval of the Board of Directors, Snabe will be granted an option to purchase 3,250,000 shares of Class B Common Stock of the Company (the “New Grant”). Once approved by the Board of Directors, the New Grant will be governed by the terms and conditions of the grant agreement between Snabe and the Company (the “Option Agreement”) and the C3.ai, Inc. 2012 Equity Incentive Plan (the “Plan”). Provided that Snabe either (a) continues to provide the Services to the Company under this Revised Agreement or (b) is appointed as a member of the Board of Directors, and provided that Snabe attends the regularly scheduled meeting of the Board of Directors during each fiscal quarter, starting in the quarter commencing November 1, 2020, then 1/20th of the New Grant will vest on the last day of each such fiscal quarter until the New Grant is either (x) fully vested or (y) Snabe’s Services are terminated under this Revised Agreement or, if appointed to the Board of Directors, Snabe subsequently leaves the Board of Directors. If Snabe fails to attend any regularly scheduled meeting of the Board of Directors, then vesting of the New Grant shall not occur for the fiscal quarter of such meeting and will be suspended (any such shares being referred to, collectively, as the “Suspended Shares”). Any Suspended Shares shall vest in a subsequent fiscal quarter, provided that Snabe satisfies the requirements for such vesting in such fiscal quarter (i.e., continuous service and attendance at the meeting of the Board of Directors), provided that no more than 1/20th of the New Grant may vest in any fiscal quarter. 2. Vesting of Original Option Grant. Notwithstanding the amendment and restatement of the Original Agreement by virtue of this Restated Agreement, and the resultant termination of the Original Agreement, if Snabe continues to provide Services under this Restated Agreement or is appointed a member of the Board of Directors, it shall constitute continuous active service to the Company for the purposes of determining vesting of the option for 250,000 shares of Class B Common Stock of the Company provided under the Original Agreement (the “Original Grant”).
