Your salary and other compensation will be subject to applicable deductions and withholdings. Bonus: You will be eligible to receive an annual target bonus of 60% of your Base Salary based upon the achievement of performance goals established separately (“Bonus”). The actual Bonus is discretionary and will be subject to the Company’s assessment of your performance, as well as business conditions at the Company. The Company also may make adjustments to the targeted amount of your Bonus, and the Bonus may be subject to approval by and adjustments at the discretion of the Board, a delegee of the Board, or the Company and subject to the terms of any applicable bonus plan separately delivered to you. Employees with a Start Date on or before September 30th are eligible for a prorated Bonus for the performance year in which they started, as determined by the Board and subject to the terms of any applicable bonus plan that will be separately delivered to you.

half of the Sign-on Bonus upon completing one year of employment with the Company after the Start Date, and you will earn the remaining half of the Sign-on Bonus on a pro rata monthly basis until you have completed two years of employment with the Company after the Start Date. In the event that your employment is terminated for Cause or you resign without Good Reason (as those terms are defined in the Company’s Change in Control Acceleration Plan (the “Acceleration Plan”)) within two years of the Start Date, you will be required to repay the unearned portion of the Sign-on Bonus to the Company. RSU Award: You will be eligible to participate in the Company’s equity incentive program, subject to approval by the Company’s Board of Directors (“Board”). We will recommend to the Board, or a delegate of the Board, that you be granted Restricted Stock Units (“RSUs”) for shares of the Company’s Common Stock representing a targeted current value of $3,000,000. The actual number of shares recommended to the Board will be based on the greater of the average closing market price of the Company’s common stock over the 30 trading day period preceding your Start Date or a floor price determined on a quarterly basis (the “Floor Price”). Your RSUs will vest over a four-year vesting schedule, subject to your continuous service to the Company through each vesting date. The terms and conditions associated with any RSUs granted to you, including vesting and other conditions, will be governed by the Company’s 2014 Stock Option and Incentive Plan (the “Plan”) and any associated restricted stock unit award agreement that you may be required to enter with the Company. Option Award:  In addition to RSUs, we believe that options provide an effective way to tie equity incentive compensation to stock price. We will recommend to the Board, or a delegate of the Board, that you be granted an option (“Option”) to purchase shares of the Company’s Common Stock representing a value of $3,000,000 (the “Option Value”). In determining the number of shares underlying the Option, our goal is to approximate the financial value of the Option over time. We do so by doubling the Option Value and then dividing the result by the greater of the average closing market price of the Company’s common stock over the 30 trading day period preceding your Start Date or the Floor Price. The exercise price per share of the Option will be the closing price of the Common Stock as listed on the New York Stock Exchange on the effective date of grant of the Option, as approved by the Board, or a delegate of the Board. Your Option will vest over a four-year vesting schedule, subject to your continuous service to the Company through each vesting date. The terms and conditions associated with any Option granted to you, including vesting and other conditions, will be governed by the Plan and any associated stock option agreement that you may be required to enter with the Company. Acceleration of the Vesting of Equity: You will be eligible to participate in the Company’s Acceleration Plan. The Acceleration Plan provides for the acceleration of the vesting of a participant’s RSUs and stock options in the event that the participant’s provision of services to the Company is terminated under certain circumstances following a change in control of the Company, subject to the terms and conditions set forth in the Acceleration Plan. The full text of the Acceleration Plan is available for your review. Benefits: You will be eligible to participate in the employee benefits and insurance programs generally made available to employees at your level, including health, dental, life and disability insurance, subject to the terms and conditions of those plans and programs, which may be modified from time to time. Details of these benefits programs, including mandatory employee contributions, DocuSign Envelope ID: 3672B045-B7C0-46B7-BD1C-4EBFC42E65B5

EXHIBIT A   ZENDESK, INC.  Employee Confidentiality and Invention Assignment Agreement    I hereby agree to the following terms regarding my employment with Zendesk, Inc. (including any parent, subsidiary or affiliate,                                      “ ​Zendesk ​”). I enter this Agreement in consideration of my salary, wages and benefits paid to me, and my continuing employment, by                                          Zendesk, with the understanding that Zendesk only agrees to employ me (or continue employing me) subject to this Agreement.      1. Proprietary Information ​. I agree that all Proprietary              Information, whether or not in writing, that I develop, learn or                      obtain in connection with my employment and which Zendesk                  has not released to the general public, is and will be the                        exclusive property of Zendesk. For purposes of this                Agreement, “ ​Proprietary Information ​” shall mean all information              relating to a person or entity’s business, technology, customers,                  prospective customers, suppliers, prospective suppliers,          business relationships or financial affairs, including, without              limitation, (a) ​corporate information ​, including plans, strategies,              methods, policies, resolutions, negotiations or litigation; (b)              marketing information ​, including strategies, methods, customer            identities, or other information about customers, prospect              identities or other information about prospects, or market                analyses or projections; (c) ​financial information ​, including cost                and performance data, debt arrangements, equity structure,              investors and holdings, purchasing and sales data and price                  lists; (d) ​personal and/or confidential information, ​including              personally identifiable information, trade secrets and other              confidential information; (e) ​operational and technological            information ​, including plans, specifications, manuals, forms,            templates, software, designs, methods, procedures, formulas,            discoveries, inventions, improvements, concepts and ideas; (f)              personnel information ​, including personnel lists, reporting or              organizational structure, resumes, personnel data,          compensation structure, performance evaluations and          termination arrangements or documents; and (g) any              information received in confidence by Zendesk from customers,                suppliers or other third parties.  2. Recognition of Zendesk’s Rights; My Obligations ​. I              will not, at any time during or after my employment, without                      Zendesk’s prior written consent, disclose any Proprietary              Information to anyone outside of Zendesk, or use or permit to                      be used any Proprietary Information for any purpose other than                    the performance of my duties as an employee of Zendesk. I will                        cooperate with Zendesk and use my best efforts to prevent the                      unauthorized disclosure of any Proprietary Information. I will                deliver to Zendesk all copies of Proprietary Information in my                    possession or control upon the earlier of a request by Zendesk                      or termination of my employment. Without limiting the                foregoing in any way, I will not (at any time during or after my                            employment), directly or indirectly, use any Proprietary              Information to call upon, solicit, divert or take away any                    customers, prospective customers, suppliers, prospective          suppliers or business of Zendesk for any purpose (other than                    for the benefit of Zendesk during my employment).  3. Security Commitment ​. ​I understand that Zendesk is              committed to a rigorous data security program. I agree to (a) if                        requested by Zendesk, undergo relevant background checks as                part of my hiring process; (b) review and comply with Zendesk’s                      security policies; (c) complete Zendesk’s security awareness              training as required by Zendesk; (d) not disclose any Proprietary                    Information via systems or channels not approved by Zendesk;                  (d) notify Zendesk immediately upon becoming aware that a                  device containing Proprietary Information is lost, stolen or                otherwise compromised; (e) notify Zendesk immediately upon            finding any system or process that could violate Zendesk’s                  security policies; and (f) otherwise comply with Zendesk’s                security program during my employment and thereafter.   4. Compliance With Zendesk Policies ​. ​I agree to act                legally and ethically in the conduct of my duties as an employee                        of Zendesk, and to abide by all applicable laws and regulations,                      as well as the provisions of the Zendesk policies, procedures,                    standards, directives, and rules as may be adopted or modified                    by Zendesk (collectively, “ ​Policies​”) from time to time. I agree to                      review such Policies regularly and, as requested by Zendesk, to                    certify as to my understanding and compliance with such                  Policies. I agree to complete all required training in a timely                      manner. I agree to timely and properly report possible or actual                      illegal and unethical behavior to Zendesk when I become aware                    of it. I further agree to fully cooperate in investigations                    undertaken by Zendesk.  5. Publicity​. ​I agree that my name, voice, picture, and                  likeness may be used in Zendesk's advertising, training aids,                  and other materials without payment of separate compensation                to me. I will not issue or release any articles, advertising,                      publicity, or other matter relating to Zendesk, or provide any                    information regarding Zendesk to any other person intending to                  do so, without Zendesk's prior written consent.  6. Rights of Others ​. I understand that Zendesk is now                  and may hereafter be subject to non-disclosure or                confidentiality agreements with third persons which require              Zendesk to protect or refrain from use of Proprietary                  Information. I agree to be bound by all relevant terms of such                        agreements in the event I have access to such Proprietary                    Information.  7. Commitment to Zendesk; Conflict of Interest​. While              an employee of Zendesk, I will devote my full-time efforts to                      Zendesk’s business and I will not engage in any other business                      activity that conflicts with my duties to Zendesk. I will advise                      Zendesk at such time as any activity of either Zendesk or                      another business presents me with a conflict of interest or the                      appearance of a conflict of interest as an employee of Zendesk.                      I will take whatever reasonable action is requested of me by                      Zendesk to resolve any conflict or appearance of conflict which                    it, in good faith, finds to exist.   8. Developments ​. I will make full and prompt disclosure                to Zendesk of all inventions, discoveries, designs, designations,                developments, methods, modifications, improvements,        processes, algorithms, databases, computer programs,          formulae, techniques, trade secrets, graphics or images, and                audio or visual works and other works of authorship (collectively                    “ ​Developments ​”), whether or not patentable or copyrightable,              that are created, made, conceived or reduced to practice by me                      (alone or jointly with others) or under my direction in the course                        of my employment. Subject to the limitations below, I                  acknowledge that all work performed by me is on a “work for                        hire” basis, and I hereby do assign and transfer and, to the                        DocuSign Envelope ID: 3672B045-B7C0-46B7-BD1C-4EBFC42E65B5

extent any such assignment cannot be made at present, will                    assign and transfer, to Zendesk and its successors and assigns                    all my right, title and interest in all Developments that (a) relate                        to the business or research and development of Zendesk; (b)                    result from tasks assigned to me by, or work otherwise                    performed for, Zendesk; or (c) result from the use of Proprietary                      Information, premises or personal property (whether tangible or                intangible) owned, leased or contracted for by Zendesk                (“ ​Company-Related Developments ​”), and all related patents,            patent applications, trademarks and trademark applications,            copyrights and copyright applications, trade secret rights and                other intellectual property and proprietary rights in all countries                  and territories worldwide and under any applicable international                convention (“ ​Intellectual Property Rights ​”). I also hereby waive                all claims to any moral rights or other special rights which I may                          have or accrue in any Company-Related Developments.    To preclude any possible uncertainty, I have set forth                  on ​Attachment 1 attached hereto a complete list of                  Developments that I have, alone or jointly with others,                  conceived, developed or reduced to practice prior to the                  commencement of my employment with Zendesk that I wish to                    have excluded from the scope of this Agreement (“​Prior                  Inventions ​”). I have also listed on ​Attachment 1 all patents and                      patent applications in which I am named as an inventor, other                      than those which have been assigned to Zendesk (“ ​Other                  Patent Rights ​”). If no such disclosure is attached, I represent                    that there are no Prior Inventions or Other Patent Rights. If, in                        the course of my employment with Zendesk, I incorporate a                    Prior Invention into a Zendesk product, process or machine or                    other work done for Zendesk, I hereby grant to Zendesk a                      nonexclusive, royalty-free, paid-up, irrevocable, worldwide          license (with the full right to sublicense) to make, have made,                      modify, use, reproduce, sell, offer for sale, publicly display and                    perform, import and otherwise fully exercise and exploit such                  Prior Invention. Notwithstanding the foregoing, I will not                incorporate, or permit to be incorporated, Prior Inventions in                  any Company-Related Development without Zendesk’s prior            written consent. I will not incorporate into any Zendesk product                    or otherwise deliver to Zendesk any open source software                  except as allowed pursuant to Zendesk’s open source software                  policy, which is available on Zendesk’s intranet.  Subject to the requirements of applicable state law, if                  any, I understand that Company-Related Developments will not                include, and the provisions of this Agreement requiring                assignment thereof to Zendesk ​do not apply to, any invention                    which qualifies fully for exclusion under the provisions of                  applicable state law, if any, attached hereto as ​Attachment 2 ​.                    However, I will also promptly disclose to Zendesk any such                    Developments for the purpose of determining whether they                qualify for such exclusion.    9. Documents and Other Materials ​. I will keep and                maintain adequate and current records of all Proprietary                Information and Company-Related Developments developed by            me during my employment, which records will be available to                    and remain the sole property of Zendesk at all times. All files,                        letters, notes, memoranda, reports, records, data, sketches,              drawings, notebooks, layouts, charts, quotations and proposals,              specification sheets, program listings, blueprints, models,            prototypes, or other written, photographic or other tangible                material containing Proprietary Information, whether created by              me or others, which come into my custody or possession, are                      the exclusive property of Zendesk to be used by me only in the                          performance of my duties for Zendesk. Any property situated                  on Zendesk’s premises and owned by Zendesk, including                without limitation computers, disks and other storage media                (and whether or not password-protected), filing cabinets or                other work areas, is subject to inspection by Zendesk at any                      time with or without notice. In the event of the termination of                        my employment for any reason, I will deliver to Zendesk all files,                        letters, notes, memoranda, reports, records, data, sketches,              drawings, notebooks, layouts, charts, quotations and proposals,              specification sheets, program listings, blueprints, models,            prototypes, or other written, photographic or other tangible                material containing Proprietary Information, and other materials              of any nature pertaining to the Proprietary Information of                  Zendesk and to my work, and will not take or keep in my                          possession any of the foregoing or any copies.    10. Enforcement of Intellectual Property Rights ​. I will              cooperate fully with Zendesk, both during and after my                  employment with Zendesk, with respect to the procurement,                maintenance and enforcement of Intellectual Property Rights in                Company-Related Developments. I will sign, both during and                after the term of this Agreement, all papers, including without                    limitation copyright applications, patent applications,          declarations, oaths, assignments of priority rights, and powers                of attorney, which Zendesk may deem necessary or desirable in                    order to protect its rights and interests in any Company-Related                    Development. If Zendesk is unable, after reasonable effort, to                  secure my signature on any such papers, I hereby irrevocably                    designate and appoint each officer of Zendesk as my agent and                      attorney-in-fact to execute any such papers on my behalf, and                    to take any and all actions as Zendesk may deem necessary or                        desirable in order to protect its rights and interests in any                      Company-Related Development.  11. Non-Solicitation ​. During and for a period of twelve                (12) months following the end of my employment (the                  “Restricted Period”), I will not, directly or indirectly, in any                    manner, solicit, entice or attempt to persuade any other                  employee or consultant of Zendesk to leave the services of                    Zendesk for any reason. I acknowledge and agree that if I                      violate any of the provisions of this ​Section 11 ​, the running of the                          Restricted Period will be extended by the time during which I                      engage in such violation(s).  12. Prior Agreements ​. I hereby represent that, except as I                  have fully disclosed previously in writing to Zendesk, I am not                      bound by the terms of any agreement with any previous                    employer or other party to refrain from competing, directly or                    indirectly, with the business of such previous employer or any                    other party. I further represent that my performance of all the                      terms of this Agreement as an employee of Zendesk does not                      and will not breach any agreement to keep in confidence                    proprietary information, knowledge or data acquired by me in                  confidence or in trust prior to my employment with Zendesk. I                      will not disclose to Zendesk or induce Zendesk to use any                      confidential or proprietary information or material belonging to                any previous employer or others.   13. Remedies Upon Breach​. I understand that the                restrictions contained in this Agreement are necessary for the                  protection of the business and goodwill of Zendesk and I                    consider them to be reasonable for such purpose. Any breach                    of this Agreement is likely to cause Zendesk substantial and                    irrevocable damage and therefore, in the event of such breach,                    Zendesk, in addition to such other remedies which may be                    available, will be entitled to specific performance and other                  injunctive relief, and without the posting of any bond.  2 DocuSign Envelope ID: 3672B045-B7C0-46B7-BD1C-4EBFC42E65B5

14. Publications and Public Statements ​. I will obtain              Zendesk’s written approval before publishing or submitting for                publication any material that incorporates or otherwise              discloses any Proprietary Information.  15. No Employment Obligation ​. I understand that this              Agreement does not create an obligation on Zendesk or any                    other person to continue my employment. I acknowledge that,                  unless otherwise agreed in a formal written employment                agreement signed on behalf of Zendesk by an authorized                  officer, my employment with Zendesk is at will and therefore                    may be terminated by Zendesk or me at any time with or                        without cause and for any reason.  16. Survival and Assignment by Zendesk ​. I understand              that my obligations under this Agreement will continue in                  accordance with its express terms regardless of any changes in                    my title, position, duties, salary, compensation or benefits or                  other terms and conditions of employment. I further understand                  that my obligations under this Agreement will continue                following the termination of my employment regardless of the                  manner of such termination and will be binding upon my heirs,                      executors and administrators. Zendesk will have the right to                  assign this Agreement to its affiliates, successors and assigns. I                    expressly consent to be bound by the provisions of this                    Agreement for the benefit of Zendesk or any parent, subsidiary                    or affiliate to whose employ I may be transferred without the                      necessity that this Agreement be resigned at the time of such                      transfer.  17. Exit Interview ​. If and when I depart from Zendesk, I                    may be required to and agree to attend an exit interview and                        sign an “Employee Exit Acknowledgement” to reaffirm my                acceptance and acknowledgement of the obligations set forth                in this Agreement.    18. Disclosure to Future Employers ​. I hereby grant              Zendesk the right to provide this Agreement in whole or in part                        to any future employer, partner, or co-venturer of mine to advise                      them of my obligations under this Agreement.  19. Severability ​. In case any provisions (or portions              thereof) contained in this Agreement shall, for any reason, be                    held invalid, illegal or unenforceable in any respect, such                  invalidity, illegality or unenforceability shall not affect the other                  provisions of this Agreement, and this Agreement shall be                  construed as if such invalid, illegal or unenforceable provision                  had never been contained herein. If, moreover, any one or                    more of the provisions contained in this Agreement shall for any                      reason be held to be excessively broad as to duration,                    geographical scope, activity or subject, it shall be construed by                    limiting and reducing it, so as to be enforceable to the extent                        compatible with the applicable law as it shall then appear.  20. Interpretation ​. This Agreement will be deemed to be                made and entered into in the State of California, and will in all                          respects be interpreted, enforced and governed under the laws                  of the State of California. I hereby agree to consent to personal                        jurisdiction of the state and federal courts situated within the                    greater San Francisco area, California for purposes of enforcing                  this Agreement, and waive any objection that I might have to                      personal jurisdiction or venue in those courts.  21. Protected Disclosures ​. ​I understand that nothing            contained in this Agreement limits my ability to communicate                  with any United States federal, state or local governmental                  agency or commission, including to provide documents or other                  information, without notice to Zendesk. I also understand that                  nothing in this Agreement limits my ability to share                  compensation information concerning myself or others, except              that this does not permit me to disclose compensation                  information concerning others that I obtain because my job                  responsibilities require or allow access to such information.  22. Defend Trade Secrets Act of 2016​. ​I understand that                  pursuant to the federal Defend Trade Secrets Act of 2016, I                      shall not be held criminally or civilly liable under any United                      States federal or state trade secret law for the disclosure of a                        trade secret that (a) is made (i) in confidence to a United States                          federal, state, or local government official, either directly or                  indirectly, or to an attorney; and (ii) solely for the purpose of                        reporting or investigating a suspected violation of law; or (b) is                      made in a complaint or other document filed in a lawsuit or                        other proceeding, if such filing is made under seal.      I UNDERSTAND THAT THIS AGREEMENT AFFECTS IMPORTANT RIGHTS.  BY SIGNING BELOW, I CERTIFY THAT I HAVE READ IT  CAREFULLY AND AM SATISFIED THAT I UNDERSTAND IT COMPLETELY.  IN WITNESS WHEREOF, ​ ​the undersigned has executed this agreement as a sealed instrument as of the date set forth below.    Signed: ___________________________________________      Name: ___________________________________________      Date: ___________________________________________        3 DocuSign Envelope ID: 3672B045-B7C0-46B7-BD1C-4EBFC42E65B5 11/23/2021 Andrea Nieto

If the FAA is found not to apply, then this Arbitration Agreement is enforceable under the laws of the state in which I am or was employed at the time I received this Arbitration Agreement. However, both parties agree that there will be no right to bring any dispute covered by this Arbitration Agreement as a class or collective action, as specified in Paragraphs 1 and 2 below. 1. Claims Covered by this Arbitration Agreement . To the maximum extent allowed by law, the Company and I mutually consent to the resolution by binding arbitration of all claims or causes of action that the Company may have against me or that I may have against the Company or the Company’s current and former owners, partners, members, officers, directors, employees, representatives and agents, all subsidiary and affiliated entities, all benefit plans, the benefit plans’ sponsors, fiduciaries, administrators, affiliates, and all successors and assigns of any of them (“Arbitrable Disputes”). Arbitrable Disputes shall include any and all disputes not specifically exempted from arbitration herein, including, but not limited to: any alleged violations of federal, state, or local constitutions, statutes, laws, ordinances, regulations or common law; any claims of wrongful termination, unlawful disparate treatment or disparate impact, or retaliation; any claims for breach of any contractor covenant of good faith and fair dealing; tort claims; and any claims arising under the Fair Labor Standards Act and similar state and local statutes. Nothing in this Arbitration Agreement alters any obligation or prerequisite to exhaust administrative remedies before asserting a claim in arbitration. 2. Claims Not Covered . Specifically excluded from this Arbitration Agreement are: (i) claims that are not arbitrable by law, which include claims for workers’ compensation and unemployment compensation benefits, and any claims which are expressly excluded from binding arbitration by controlling law or public policy; (ii) claims under California's Labor Code Private Attorney General Act, Labor Code §§ 2698 et seq. ("PAGA"), to the extent the operative law at the time a PAGA claim is made precludes a pre-dispute waiver of the right to bring such claims on a representative basis (if the operative law changes during the pendency of a PAGA claim, and pre-dispute waivers of the right to bring PAGA claims on a representative basis become enforceable, then the parties intend and agree that PAGA claims would become covered claims under this Agreement); and (iii) any claims for unlawful harassment based on a protected DocuSign Envelope ID: 3672B045-B7C0-46B7-BD1C-4EBFC42E65B5

Page 1 of 5 category under Title VII of the Civil Rights Act of 1964, the Americans with Disabilities Act, the Age Discrimination in Employment Act (as amended by the Older Workers Benefits Protection Act), the California Fair Employment and Housing Act, and any other federal, state, or local statute similarly prohibiting harassment based on enumerated protected categories or classifications; provided , however , that claims under such statutes are only excluded from the agreement to arbitrate to the extent they allege harassment – as distinct from disparate treatment, wrongful termination, and/or disparate impact (“Excluded Claims”). To the extent that the parties’ dispute involves Arbitrable Disputes and Excluded Claims, the parties agree to bifurcate and stay the Excluded Claims pending the resolution of the arbitration proceedings. Either party may apply to a court of competent jurisdiction for temporary or preliminary injunctive relief in connection with an Arbitrable Dispute, but only upon the ground that the award to which that party may be entitled may be rendered ineffectual without such relief. I understand that this Arbitration Agreement does not prohibit me from filing or maintaining an administrative charge or complaint with a local, state, or federal administrative body that is authorized to enforce or administer laws related to employment, including but not limited to the Equal Employment Opportunity Commission, Department of Labor, or the National Labor Relations Board. I understand that this Agreement does, however, preclude me from pursuing any court action regarding any such claim, except as permitted by law. This Arbitration Agreement does not restrict my rights to engage in concerted activities under Section 7 of the National Labor Relations Act. I understand that I will not be retaliated against, disciplined or threatened with discipline as a result of exercising my rights under Section 7 of the National Labor Relations Act by the filing of or participation in a class or collective action in any forum. 3. Class Action Waiver . Except for Excluded Claims, the Company and I expressly intend and agree that: (a) class action and representative action procedures are hereby waived and shall not be asserted, nor will they apply, in any arbitration pursuant to this Agreement; (b) neither party will assert class action or representative action claims against the other in arbitration or otherwise, and (c) the arbitrator is not empowered to consolidate claims of different individuals into one proceeding, or to hear an arbitration as a class arbitration (“Class Action Waiver”). To the extent a court or the arbitrator determines that this Class Action Waiver is invalid, for any reason, it shall not be severable from this Agreement and the class or collective claims will be considered Excluded Claims that must be litigated in a civil court of competent jurisdiction. Notwithstanding any other clause contained in this Arbitration Agreement, any claim that all or part of the Class Action Waiver is invalid, unenforceable void or voidable may be determined only by a court of competent jurisdiction and not by an arbitrator. The Class Action Waiver shall be severable when a dispute is filed as an individual action and severance is necessary to ensure that the individual action proceeds in arbitration. 4. Waiver of Right to Court or Jury Trial . I understand that, by signing this Arbitration Agreement, both the Company and I are giving up any right we may have to a trial by jury and are giving up rights of appeal following the rendering of a decision except as applicable law provides for judicial review of arbitration decisions.

Page 2 of 5 5. Arbitration Procedures . The Company and I agree that, except as provided in the Arbitration Agreement, any arbitration shall be in accordance with and under the auspices and rules of JAMS, Inc. (“JAMS”) for the resolution of employment disputes, pursuant to its employment arbitration rules & procedures. The JAMS Employment Arbitration Rules and Procedures (the “JAMS Rules”) are available at Under no circumstances shall the JAMS Class Action Procedures apply to any arbitration held pursuant to this Arbitration Agreement. Notwithstanding anything in the JAMS Rules, the arbitrator will not have the authority to determine whether this arbitration provision or any portion of it is enforceable, revocable or valid, the arbitrability of disputes, or whether claims may be arbitrated on a class, collective, or representative basis. The arbitrator shall apply the substantive state or federal law (and the law of remedies, if applicable) as applicable to the claim(s) asserted. The arbitrator shall provide the Parties with a written decision explaining his or her findings and conclusions. The Arbitrator's decision shall be final and binding upon the Parties. The parties shall be entitled to conduct discovery to the full extent authorized by governing law. The parties agree that the arbitrator shall have the power to decide any motions brought by any party to the arbitration, including motions for summary judgment and/or adjudication, discovery motions, motions to dismiss, and demurrers prior to any arbitration hearing. The Company and I agree that any arbitration under this Arbitration Agreement shall be conducted in San Francisco County or the site of the closest JAMS office to my place of employment. The arbitrator’s decision regarding the claims shall be final and binding upon the parties, and shall be enforceable in any court having jurisdiction thereof. I agree that the arbitrator shall have the power to award any remedies available under applicable law, and that the arbitrator shall award attorneys’ fees and costs to the prevailing party, except as prohibited by law. 6. Arbitration Fees and Costs . I agree that each party shall be responsible for paying such party’s own attorneys’ fees and costs. To the extent I bring a claim against the Company, the Company shall pay for the costs of arbitration, including any administrative or hearing fees charged by the arbitrator or JAMS, except that I shall pay any filing fees associated with any arbitration that I initiate, but only so much of the filing fees as I would have instead paid had I filed a complaint in a court of law. To the extent any of the foregoing cost-splitting provisions are found not to comply with such then-applicable law, the arbitrator shall reform this Arbitration Agreement such that it is enforceable and consistent with then-applicable decisional or statutory law. 7. Modification/Entire Agreement . This Arbitration Agreement to arbitrate shall survive the termination of my employment. It can only be revoked or modified by a writing signed by the parties that specifically states an intent to revoke or modify this Arbitration Agreement. This is the complete agreement of the parties on the subject of arbitration of disputes (except for any arbitration agreement in connection with any pension or benefit plan). This Arbitration Agreement supersedes any prior or contemporaneous oral or written understanding on the subject. No party is relying on any representations, oral or written, on the subject of the effect, enforceability, or meaning of this Arbitration Agreement, except as specifically set forth in this Arbitration Agreement. If any provision of this Arbitration Agreement is found to be DocuSign Envelope ID: 3672B045-B7C0-46B7-BD1C-4EBFC42E65B5

Page 3 of 5 unenforceable, in whole or in part, such finding shall not affect the validity of the remainder of this Arbitration Agreement and this Arbitration Agreement shall be reformed to the greatest extent possible to ensure that the resolution of all conflicts between the parties are resolved by neutral, binding arbitration. 8. Violation of this Agreement . Should any party to this Arbitration Agreement pursue any arbitrable dispute by any method other than arbitration, the responding party shall recover from the initiating party all damages, costs, expenses and attorneys’ fees incurred as a result of such action. 9. Not an Employment Agreement . This Arbitration Agreement is not and shall not be construed to create any contract of employment, express or implied. Nor does this Arbitration Agreement alter the at-will status of any employment. [Signatures to follow on the next page.] DocuSign Envelope ID: 3672B045-B7C0-46B7-BD1C-4EBFC42E65B5
