Advisor Agreement between Sumo Logic, Inc. and Sydney Carey

This Advisor Agreement (the “Agreement”) is entered into by and between Sumo Logic, Inc. (the “Company”), and Sydney Carey (the “Advisor”) effective as of August 3, 2021 (the “Effective Date”), the day after your employment with the Company as its Chief Financial Officer will terminate. The Company desires to retain Advisor as an independent contractor to perform certain advisory services for the Company, and Advisor is willing to perform such services, on terms set forth more fully below. In consideration of the mutual promises contained herein, and other good and valuable consideration, the parties agree as follows:

(a)Services. The Advisor will serve as an advisor to the Company and advise the Company’s Chief Executive Officer (“CEO”) and/or Board of Directors (the “Board”) at reasonable times, in matters related to the Company’s business, to assist in the transition of your duties and responsibilities as Chief Financial Officer of the Company (the “Services”). The Services may be provided by Advisor, and consultation may be sought by the Company, over the telephone, at the Company’s offices, or another reasonable location or through written correspondence.

(b)Compensation. As full consideration for the Services provided by Advisor under this Agreement, notwithstanding anything to the contrary contained in Advisor’s outstanding equity incentive awards covering shares of Company common stock (the “Equity Awards”), vesting will continue through and including October 31, 2021, subject to Advisor continuing to provide Services through any applicable vesting date. Advisor agrees that the vesting of any Equity Awards will cease after October 31, 2021 regardless of whether Advisor continues to provide Services and any unvested Equity Awards will terminate and be cancelled effective November 1, 2021, assuming Advisor hadn’t ceased providing Services prior to that date. Advisor’s outstanding Equity Awards that are stock options will continue to be governed by the option agreements memorializing such awards will otherwise remain in effect during the Term (as defined below), including that any post-termination exercise period will not commence until Services under this Agreement cease.

(c)Release Agreement. Advisor will execute the release agreement attached hereto as Exhibit A (the “Release”) on the same date as this Agreement. As consideration for executing and not revoking the Release, Advisor will receive a lump sum payment equal to the bonus that Advisor would have otherwise been paid to Advisor under the Company’s Executive Incentive Compensation Plan for the fiscal quarter ended July 31, 2021, as determined by the Compensation and Talent Committee of the Board, as if she had continued to be employed as the Company’s Chief Financial Officer through such date. Advisor agrees and acknowledges that she would not otherwise be entitled to earn or otherwise be paid the bonus absent executing and not revoking the Release.

2.CONFIDENTIALITY; NON-SOLICITATION

(a)Definition. “Confidential Information” means any Company proprietary information, technical data, trade secrets or know-how, including, but not limited to, research, product plans, products, services, customers, customer lists, databases, markets, software, developments, inventions, processes, formulas, technology, designs, drawings, engineering, hardware configuration information, marketing, finances or other business information disclosed by the Company either directly or indirectly in writing, orally or by drawings or inspection of equipment.

(b)Non-Use and Non-Disclosure. Advisor will not, during or subsequent to the term of this Agreement, use the Company’s Confidential Information for any purpose whatsoever other than the performance of the Services on behalf of the Company or disclose the Company’s Confidential Information to any third party. It is understood that said Confidential Information shall remain the sole property of the Company. Advisor further agrees to take all reasonable precautions to prevent any unauthorized disclosure of such Confidential Information including, but not limited to, having each employee of Advisor, if any, with access to any Confidential Information, execute a nondisclosure agreement containing provisions in the Company’s favor identical to Sections 2, 3 and 4 of this Agreement. Confidential Information does not include information which (i) is known to Advisor at the time of disclosure to Advisor by the Company as evidenced by written records of Advisor, (ii) has become publicly known and made generally available through no wrongful act of Advisor, or (iii) has been rightfully received by Advisor from a third party who is authorized to make such disclosure. Notwithstanding the foregoing, the Advisor may disclose any Confidential Information that is required to be disclosed by law, government regulation or court order.

(c)Other Entity’s Confidential Information. Advisor agrees that Advisor will not, during the term of this Agreement, improperly use or disclose any proprietary information or trade secrets of any other person or entity with which Advisor has an agreement or duty to keep in confidence information acquired by Advisor, if any, and that Advisor will not bring onto the premises of the Company any unpublished document or proprietary information belonging to such person or entity unless consented to in writing by such person or entity.

(d)Third Party Confidential Information. Advisor recognizes that the Company has received and in the future will receive from third parties their confidential or proprietary information subject to a duty on the Company’s part to maintain the confidentiality of such information and to use it only for certain limited purposes. Advisor agrees that Advisor owes the Company and such third parties, during the term of this Agreement and thereafter, a duty to hold all such confidential or proprietary information in confidence and not to disclose it to any person, firm or corporation or to use it except as necessary in carrying out the Services for the Company consistent with the Company’s agreement with such third party.

(e)Return of Materials. Upon the termination of this Agreement, or upon Company’s earlier request, Advisor will deliver to the Company all of the Company’s property or Confidential Information that Advisor may have in Advisor’s possession or control.

(a)Assignment. Advisor agrees that all copyrightable material, notes, records, drawings, designs, inventions, improvements, developments, discoveries and trade secrets (collectively, “Inventions”) conceived, made or discovered by Advisor, solely or in collaboration with others, during the period of this Agreement which relate to the business of the Company that Advisor may be directed to undertake, investigate or experiment with, such investigation or experimentation in the line of business of Company in performing the Services hereunder, are the sole property of the Company.

(b)Further Assurances. Advisor agrees to assist Company, or its designee, at the Company’s expense, in every proper way to secure the Company’s rights in the Inventions and any copyrights, patents, mask work rights or other intellectual property rights relating thereto in any and all countries, including the disclosure to the Company of all pertinent information and data with respect thereto, the execution of all applications, specifications, oaths, assignments and all other instruments which the Company shall deem necessary in order to apply for and obtain such rights and in order to assign and convey

to the Company, its successors, assigns and nominees the sole and exclusive right, title and interest in and to such Inventions, and any copyrights, patents, mask work rights or other intellectual property rights relating thereto. Advisor further agrees that Advisor’s obligation to execute or cause to be executed, when it is in Advisor’s power to do so, any such instrument or papers shall continue after the termination of this Agreement.

Advisor agrees that if in the course of performing the Services, Advisor incorporates into any Invention developed hereunder any invention, improvement, development, concept, discovery or other proprietary information owned by Advisor or in which Advisor has an interest, Advisor shall inform Company in writing before incorporating such invention, improvement, development, concept, discovery or other proprietary information into any Invention. Advisor shall not incorporate any invention, improvement, development, concept, discovery or other proprietary information owned by any third party into any Invention without Company’s prior written permission.

(d)Attorney-in-Fact. Advisor agrees that if the Company is unable because of Advisor’s unavailability, dissolution, mental or physical incapacity, or for any other reason, to secure Advisor’s signature to apply for or to pursue any application for any United States or foreign patents or mask work or copyright registrations covering the Inventions assigned to the Company above, then Advisor hereby irrevocably designates and appoints the Company and its duly authorized officers and agents as Advisor’s agent and attorney-in-fact, to act for and in Advisor’s behalf and stead to execute and file any such applications and to do all other lawfully permitted acts to further the prosecution and issuance of patents, copyright and mask work registrations thereon with the same legal force and effect as if executed by Advisor.

Advisor certifies that Advisor has no outstanding agreement or obligation that is in conflict with any of the provisions of this Agreement, or that would preclude Advisor from complying with the provisions hereof.

(a)Term. This Agreement will commence on the Effective Date and will continue until December 31, 2021 (the “Term”).

(b)Termination. The Company may terminate this Agreement by providing Advisor with fourteen (14) days prior written notice.

Notices shall be deemed effectively given (i) upon delivery when delivered personally or via e-mail; (ii) one day after sending when sent by private express mail service (such as Federal Express); or (iii) four days after sending when sent by United States mail, postage prepaid, registered or certified mail, return receipt requested. The Company agrees that it will not exercise its right to terminate pursuant to this subsection before October 15, 2021 to permit all scheduled vesting of Advisor’s outstanding equity incentive awards prior to that date.

It is the express intention of the parties that Advisor is an independent contractor. Nothing in this Agreement shall in any way be construed to constitute Advisor as an agent, employee or representative of the Company, but Advisor shall perform the Services hereunder as an independent contractor. The Advisor shall not enter into any agreements nor incur any obligations on behalf of the Company. Advisor agrees to furnish (or reimburse the Company for) all tools and materials necessary to accomplish this contract, and shall incur all expenses associated with performance, except as expressly agreed upon by the Company.

Neither this Agreement nor any right hereunder or interest herein may be assigned or transferred by Advisor without the express written consent of the Company.

Advisor agrees that for a period of eighteen (18) months following the Term of this Agreement, Advisor will not encourage or solicit any employee or consultant of the Company to leave Company for any reason.

The invalidity or unenforceability of any provision of this Agreement, or any terms thereof, shall not affect the validity of this Agreement as a whole, which shall at all times remain in full force and effect.
