Transition Plan and Release Agreement between the Registrant and Richard Campione, dated as of January 8, 2018

Between the date of this letter through the Termination Date, you will continue to be paid your current annualized base salary of $400,000. You will continue to participate in Splunk’s equity plans in which you are currently participating, and the equity awards you previously received will continue to vest in accordance with the terms of the applicable equity plan. You will also continue to participate in Splunk’s fiscal year 2018 annual executive bonus plan (the “FY 2018 Bonus Plan”) and benefit plans in which you are currently participating;

You acknowledge that the amounts stated in paragraph (1) above comprise all salary, bonus, compensation and benefits that will be payable or provided to you as a result of your continued employment with Splunk, and you are not eligible to receive any compensation or benefits under any other Company plan or program. All amounts will be paid in accordance with Splunk’s standard practices, and less deductions and withholdings;

You will remain an “at will” employee, which means that either you or Splunk may terminate your employment at any time, with or without cause and with or without reason. You must comply with all applicable Splunk policies and practices (including, but not limited to, the Code of Business Conduct and Ethics and Insider Trading Policy), and the terms of the attached Release Agreement both prior to and after your Termination Date, as applicable;

Prior to the Termination Date you will, as requested, remain available in person, by phone and electronic means and provide reasonable and timely assistance to answer questions and transition your duties and responsibilities; and

Both prior to and after the Termination Date, you agree that at the Company’s request, you will provide reasonable assistance to the Company or any associated company in any threatened or actual litigation, arbitration, investigation or regulatory proceeding concerning it or them where you have knowledge of any facts or other matters which the Company or any associated company reasonably considers is relevant to such legal proceedings (including but not limited to giving statements, affidavits, testimony, meeting with legal and other professional advisers, attending interviews, hearings and giving evidence). The Company will, to the extent permitted by law and applicable court rules, reimburse you for reasonable out-of-pocket expenses you incur in extending such cooperation, in accordance with the Company’s Travel and Expense Policy.

A lump sum payment equal to six (6) months of your then-current base salary in the amount of $200,000;

A lump sum payment equal to the unpaid portion of your bonus under the FY 2018 Bonus Plan based on actual achievement of the applicable performance metrics for fiscal 2018, which will paid to you at the same time as bonuses under the FY 2018 Bonus Plan are paid to the Company’s other senior executive officers participating in the FY 2018 Bonus Plan, but in no event later than April 15, 2018. You acknowledge that your annual target bonus for fiscal 2018 is $280,000 and you previously received a mid-year bonus of $140,000 under the FY 2018 Bonus Plan.

Your coverage under the Splunk group health plans is scheduled to end on January 31, 2018. However, you will have the opportunity to continue the benefits under the Splunk group health plans under the Consolidated Omnibus Budget Reconciliation Act of 1985 (“COBRA”) to the same extent previously provided, for six (6) months, through July 31, 2018, or until you become eligible for group health insurance benefits from another employer or entity, whichever occurs first. You understand that you must inform Splunk if you receive group health coverage from another employer or entity before July 31, 2018, and that you may not increase the number of designated dependents, if any, during this time unless you do so at your own expense. The period of such Splunk-paid COBRA coverage shall be considered part of your COBRA coverage entitlement period, and may, for tax purposes, be considered income to you. This benefit will only be provided to the extent allowable by law. If such payment of COBRA premiums would result in a Splunk excise tax, then no such premiums will be paid, and if doing so would not cause imposition of an excise tax you will be paid a single lump sum of $12,000. You have been advised by Splunk to consult with Discovery Benefits or an advisor of your choice regarding COBRA continuation coverage or other coverage options through the Health Insurance Marketplace, Medicaid or other group health plan coverage options (such as a spouse’s plan) through what is called a “special enrollment” period. Splunk does not guarantee or imply that a “special enrollment” period or an “open enrollment” period will be available to you on, or shortly after July 31, 2018;

Acceleration of vesting as to six (6) months of shares subject to all Splunk equity awards which have been granted to you (the “Equity Awards”). With respect to the Splunk performance stock units that were granted to you during fiscal 2018 (the “PSU”), the PSU shall be treated pursuant to the terms of the PSU agreement, such that (a) the number of shares that will become earned and eligible to vest under the PSU agreement and the vesting provisions in the previous sentence will be calculated based on actual performance during fiscal 2018 as determined by the compensation committee of the Company’s board of directors following the completion of the Company’s annual financial statement audit for fiscal 2018, which is expected to occur in late March 2018 (such date, the “Determination Date”) and (b) the “Vesting Commencement Date” for such earned PSU shares will be March 10, 2018. For the avoidance of doubt, any shares subject to Equity Awards (including the PSU) that (x) otherwise are scheduled to vest after July 31, 2018 shall not vest and shall be cancelled on the Termination Date and (y) with respect to the PSU, are not earned as determined by the Committee shall be cancelled on the Determination Date. For a summary of the vested and forfeited shares subject to Equity Awards, please see Schedule 1;

Outplacement services for up to six (6) months following your Termination Date will be provided by an outplacement services firm selected by Splunk. Splunk will pay the outplacement services firm directly;

If, prior to the Termination Date, you are terminated for Cause (as that term is defined in your Offer Letter dated October 12, 2016) (the “Employment Letter”), you will forfeit your right to receive the Severance Benefits; and

Effective as of your Termination Date, your Employment Letter shall terminate, however paragraphs 5 (Confidentiality); 6 (At-Will Employment); 8 (Section 409A Matters); 9 (Definitions); 11 (Policies); and 12 (Arbitration) shall continue in full force and effect, except as specifically modified by the Release Agreement.

Release of All Claims. On behalf of my heirs, spouse and assigns, I hereby completely release and forever discharge Splunk, its past and present parent companies, subsidiaries, affiliates, related entities, and each of their past and present agents, officers, directors, shareholders, employees, attorneys, insurers, successors and assigns (collectively referred to as the “Company”) from any and all claims, of any and every kind, nature and character, known or unknown, foreseen or unforeseen, based on any act or omission occurring prior to the date of this Release Agreement, to the fullest extent allowed by law, including but not limited to any claims arising out of my offer of employment, my employment, my compensation, or termination of my employment with Splunk. The matters released include, but are not limited to, any claims under federal, state or local laws, including claims arising under the Age Discrimination in Employment Act of 1967 (“ADEA”) as amended by the Older Workers’ Benefit Protection Act (“OWBPA”), and any common law tort, contract or statutory claims, and any claims for attorneys’ fees and costs. This Release Agreement does not release claims that cannot be released as a matter of law, including, but not necessarily limited to, any Protected Activity (as defined below), nor any indemnification rights available under any indemnification agreement I signed with the Company that is in effect immediately prior to my Termination Date, Company Bylaws, or under applicable law (collectively, the “Indemnification Rights”). Nothing in this Release Agreement shall be construed to prohibit me from filing a charge with a federal, state or local agency or participating in any investigation or proceeding conducted by a government agency. Notwithstanding the foregoing, to the maximum extent permitted by law, I agree to waive my right to recover monetary damages from the Company in any charge, complaint, or lawsuit filed by me or by anyone else on my behalf for any released claims. Further, claims challenging the validity of this Release Agreement under the ADEA as amended by the OWBPA are not released.

Waiver of Unknown Claims. I understand and agree that this Release Agreement extinguishes all claims, whether known or unknown, foreseen or unforeseen. I expressly waive any rights or benefits under Section 1542 of the California Civil Code, or any equivalent statute. California Civil Code Section 1542 provides as follows:

Enforcement of This Release Agreement. I also understand and agree that if any suit, affirmative defense, or counterclaim is brought to enforce the provisions of this Release Agreement, with the exception of a claim brought by me as to the validity of this Release Agreement under the ADEA as amended by the OWBPA, the prevailing party shall be entitled to its costs, expenses, and attorneys’ fees as well as any and all other remedies specifically authorized under the law.

Representation Concerning Filing of Legal Actions; Covenant Not to Sue. I represent that, as of the date of this Release Agreement, I have not filed any lawsuits, charges, complaints, petitions, claims or other accusatory pleadings against the Company in any court or with any governmental agency. To the maximum extent permitted by applicable law, I agree not to pursue any action nor seek damages or any other remedies for any released claims. I agree to execute any and all documents necessary to request dismissal or withdrawal, or to opt-out of such claims, with prejudice.

No Disparagement. Subject to Section 7 below, I agree not to make any voluntary statements, written or oral, or cause or encourage others to make any such statements that defame, disparage or criticize the personal and/or business reputations, practices or conduct of the Company or its employees. This Section 5 shall not apply to communications with government agencies.

Return of Splunk Property. By signing this Release Agreement, I represent and warrant that I have returned to Splunk on the date of the Transition Letter, all Splunk materials, documents containing confidential, proprietary or trade secret information (regardless of the media or forum on which they are kept) including all copies and excerpts of the same, and property and equipment, including but not limited to laptop computers and other devices, corporate credit cards, building keys or access

Protected Activity Not Prohibited. I understand that nothing in this Agreement shall in any way limit or prohibit me from engaging in any Protected Activity. For purposes of this Agreement, “Protected Activity” shall mean filing a charge, complaint, or report with, or otherwise communicating, cooperating, or participating in any investigation or proceeding that may be conducted by, any federal, state or local government agency or commission, including the Securities and Exchange Commission, the Equal Employment Opportunity Commission, the Occupational Safety and Health Administration, and the National Labor Relations Board (“Government Agencies”). I understand that in connection with such Protected Activity, I am permitted to disclose documents or other information as permitted by law, and without giving notice to, or receiving authorization from, Splunk. Notwithstanding the foregoing, I agree to take all reasonable precautions to prevent any unauthorized use or disclosure of any information that may constitute Company confidential information under the Employee Invention Assignment and Confidentiality Agreement, attached hereto in Attachment 2, which remains in full force and effect, to any parties other than the Government Agencies. I further understand that “Protected Activity” does not include the disclosure of any Company attorney-client privileged communications. Any language in the Employee Invention Assignment and Confidentiality Agreement regarding my right to engage in Protected Activity that conflicts with, or is contrary to, this paragraph is superseded by this Agreement. In addition, pursuant to the Defend Trade Secrets Act of 2016, I am notified that an individual will not be held criminally or civilly liable under any federal or state trade secret law for the disclosure of a trade secret that (i) is made in confidence to a federal, state, or local government official (directly or indirectly) or to an attorney solely for the purpose of reporting or investigating a suspected violation of law, or (ii) is made in a complaint or other document filed in a lawsuit or other proceeding, if (and only if) such filing is made under seal. In addition, an individual who files a lawsuit for retaliation by an employer for reporting a suspected violation of law may disclose the trade secret to the individual’s attorney and use the trade secret information in the court proceeding, if the individual files any document containing the trade secret under seal and does not disclose the trade secret, except pursuant to court order.

Miscellaneous. I acknowledge that during my employment I obtained confidential, proprietary and trade secret information, including information relating to Splunk’s products, plans, designs, employees, agents, consultants and other valuable confidential information. I agree not to use or disclose any such confidential information unless required by subpoena or court order, and I will first give Splunk written notice of such subpoena or court order with reasonable advance notice to permit Splunk to oppose such subpoena or court order if it chooses to do so.

Confidentiality. I agree that I will not disclose voluntarily or allow anyone else to disclose either the existence, reason for or contents of this Release Agreement without Splunk’s prior written consent, unless required to do so by law. Notwithstanding this provision, I am authorized to disclose this Release Agreement to my spouse, attorneys and tax advisors on a “need to know” basis, on the condition that they agree to hold the terms of the Release Agreement, including the settlement payments, in strictest confidence. I am further authorized to make appropriate disclosures as required by law, provided that I notify Splunk in writing of such legal obligations to disclose at least five (5) business days in advance of disclosure.

Severability. In the event any provision of this Release Agreement shall be found unenforceable by an arbitrator or a court of competent jurisdiction, the provision shall be deemed modified to the extent necessary to allow enforceability of the provision as so limited, it being intended that Splunk shall receive the benefits contemplated herein to the fullest extent permitted by law. If a deemed modification is not satisfactory in the judgment of such arbitrator or court, the unenforceable provision shall be deemed deleted, and the validity and enforceability of the remaining provisions shall not be affected thereby.

Entire Agreement. This Release Agreement constitutes the entire agreement between myself and Splunk with respect to any matters referred to in the Release Agreement. The Release Agreement supersedes any and all other agreements between myself and Splunk, except for the Transition Letter, the Employee Invention Assignment and Confidentiality Agreement, the agreements and plan governing the Equity Awards (as defined in the Transition Letter), and the Indemnification Rights.
