The Executive shall also be provided with information regarding the Consolidated Omnibus Budget Reconciliation Act of 1985, as amended (“COBRA”) under separate cover.

(f)The parties acknowledge and agree that all notice obligations under Section 4(a) of the Employment Agreement have been satisfied. The Executive and the Company each acknowledge and agree that the ending of the Executive’s employment is a termination by him other than for Good Reason for purposes of the Employment Agreement outside of a Change in Control Period. The Executive acknowledges and agrees that the hiring of the New CFO did not and shall not constitute “Good Reason” for purposes of the Executive’s Employment Agreement. The Executive further acknowledges and agrees that the payments and benefits set forth in this Agreement are the exclusive payments and benefits to be provided to the Executive in connection with the ending of his employment, and that he is not entitled to any other severance pay, benefits or equity rights, including without limitation pursuant to the Employment Agreement or any severance plan, or program or arrangement.

Subject to satisfying the Conditions (as defined below), with respect to the Company’s annual cash incentive compensation plan for the fiscal year ended March 31, 2023 (“FY23 STI Plan”), the Executive will remain eligible to receive a cash bonus under the FY23 STI Plan based upon actual performance for FY 2023 as determined in accordance with the FY23 STI Plan, despite not being employed by the Company on the measurement confirmation and payout date as otherwise required by the FY23 STI Plan, prorated based on the Termination Date. Any such prorated bonus earned under the FY23 STI Plan shall be paid at the same time as bonuses under

Subject to satisfying the Conditions, the Executive’s time-based equity awards that would have vested if the Executive had remained employed by the Company through February 15, 2023 shall be accelerated and become immediately vested on the later of (i) the Termination Date and (ii) the Effective Date of this Agreement. The remainder of the Executive’s equity awards that are not vested through the Termination Date, shall not be accelerated and shall cease vesting on the Termination Date, provided that the Executive’s unvested equity awards shall be held in abeyance until the earlier of (i) the date that is three (3) months after the Termination Date, at which time they will terminate or be forfeited and (ii) the occurrence of the first event constituting the consummation of a Change in Control, at which time they will accelerate and 100% of the then-unvested shares shall become fully vested immediately prior to such Change in Control.

To receive Prorated STI Bonus and the Limited Acceleration, as defined above, the Executive must satisfy each of the following “Conditions”: (i) enter into and comply with this Agreement, including but not limited to the Continuing Obligations (as defined below); (ii) not be terminated by the Company for Cause (as defined in the Employment Agreement and subject to any provisions for cure contained therein); and (iii) not resign before December 31, 2022 without the prior written consent of the Company’s CEO.

In consideration for, among other terms, the opportunity to remain employed by the Company through the Executive’s elected resignation date of December 31, 2022 and to receive the Prorated STI Bonus and Limited Acceleration (the “Transition Benefits”), Executive, except as provided below, irrevocably and unconditionally releases and forever discharges the Company, Parent, all of their respective affiliated and related entities, each of the foregoing’s respective predecessors, successors and assigns, employee benefit plans and the fiduciaries of such plans, and the current and former officers, directors, shareholders, employees, attorneys, accountants, fiduciaries and agents of each of the foregoing in their official and personal capacities (collectively referred to as the “Releasees”) generally from all claims, demands, debts, damages and liabilities of every name and nature, known or unknown, that, as of the date when the Executive signs this Agreement, he has, ever had, now claims to have or ever claimed to have had against any or all of the Releasees (“Claims”). Except as provided below, this release includes, without limitation, the complete waiver and release of all Claims: arising in connection with or under the Employment Agreement, the Prior Agreement or any other agreement between the Executive and any of the Releasees; of breach of express or implied contract; of wrongful termination of employment, whether in contract or tort; of intentional, reckless or negligent infliction of emotional distress; of breach of any express or implied covenant of employment, including the covenant of good faith and fair dealing; of interference with contractual or advantageous relations, whether prospective or existing; of deceit or misrepresentation; of discrimination or retaliation under federal, state or local law, including, without limitation, Title VII of the Civil Rights Act of 1964, the Americans with Disabilities Act, the Age Discrimination in Employment Act or the Massachusetts Fair Employment Practices Act, each as amended; under any federal, state, local or foreign statute, rule, ordinance or regulation; of promissory estoppel or detrimental reliance; of violation of public policy; for wages, bonuses, incentive compensation, vacation pay or any other compensation or benefits, whether under the Massachusetts Wage Act, or otherwise; for fraud, slander, libel, defamation, disparagement,

personal injury, negligence, compensatory or punitive damages, or any other Claim for damages or injury of any kind whatsoever; and for monetary recovery, injunctive relief, attorneys’ fees, experts’ fees, medical fees or expenses, costs and disbursements. The Executive understands that, except as provided below, this general release of Claims includes, without limitation, any and all Claims related to the Executive’s employment by the Company (including without limitation, any Claims against the Company or Parent in respect of any stock-based awards of any kind) and the termination of his employment, and all Claims as a stockholder or option holder arising up to and through the date that the Executive signs this Agreement. The Executive represents that he has not assigned to any third party and has not filed with any agency or court any Claim released by this Agreement. Notwithstanding anything to the contrary contained in this Agreement, this general release does not include or extend to and will not preclude: (a) any rights or claims that may arise out of acts or events that occur after the date on which the Executive signs this Agreement; (b) Claims that cannot be released as a matter of law; (c) the Executive’s rights or obligations under this Agreement and any claims for breach of the provisions of this Agreement, or to enforce this Agreement; (d) the Executive’s rights, if any, to indemnification by the Company pursuant to the Company’s By-Laws (as amended) and other organizational documents, the Indemnification Agreement date August 1, 2019, and applicable law, and coverage, if any, under applicable directors’ and officers’ insurance policies; (e) any claims or rights the Executive may have to any vested benefits or rights under any employee benefit, welfare or retirement pension plans; (f) non-termination related claims under the Employee Retirement Income Security Act (29 U.S.C. § 1001 et seq.), as amended; (g) any rights and/or claims the Executive may have under the Consolidated Omnibus Budget Reconciliation Act of 1985 (“COBRA”); and (h) any rights the Executive may have to exercise vested stock options.

(b)Return of Property. The Executive shall, on or before Termination Date (or an earlier date if requested by the Company), immediately return to the Company all Company property, including, without limitation, his Company laptop, computer equipment, software, keys and access cards, credit cards, files and any documents (including computerized data and any copies made of any computerized data or software) containing information concerning the Company, its business or its business relationships (“Company Property”), without deleting or altering any Company or customer information. After returning all Company Property, the Executive commits to deleting and finally purging any duplicates of files or documents that may contain Company or customer information from any non-Company computer or other device that remains the Executive’s property after the Termination Date. The obligations contained in this Section 7(b) are supplemental to, and not in lieu of, any return of property obligations the Executive has pursuant to the Restrictive Covenants Agreement.

(c)Cooperation. During and after the Executive’s employment, the Executive shall cooperate fully with the Company in (i) the defense or prosecution of any claims or actions now in existence or which may be brought in the future against or on behalf of the Company which relate to events or occurrences that transpired while the Executive was employed by the Company, and (ii) the investigation, whether internal or external, of any matters about which the Company believes the Executive may have knowledge or information. The Executive’s full cooperation in connection with such claims, actions or investigations shall include, but not be limited to, being available to meet with counsel to answer questions or to prepare for discovery or trial and to act as a witness on behalf of the Company at mutually convenient times. During

and after the Executive’s employment, the Executive also shall cooperate fully with the Company in connection with any investigation or review of any federal, state or local regulatory authority as any such investigation or review relates to events or occurrences that transpired while the Executive was employed by the Company. The Company shall reimburse the Executive for any reasonable out-of-pocket expenses incurred in connection with the Executive’s performance of obligations pursuant to this Section 7(c).

(d)Noncompetition. In order to protect the Company’s proprietary information and goodwill, and in connection with the Executive’s separation from employment with the Company, the Executive agrees that until December 31, 2023 (the “Restricted Period”), the Executive shall not, anywhere in the world, commence employment with or render services, directly or indirectly, in any capacity, to any Competing Organization. “Competing Organization” means any vendor in the application performance monitoring and observability markets, including, without limitation, Datadog Inc., New Relic Inc., AppDynamics, Splunk Inc. and Elastic NV. The Executive acknowledges that this covenant is necessary because the Company’s legitimate business interests cannot be adequately protected solely by the other covenants in this Agreement. This Section 7(d) supersedes any other noncompetition obligations that the Executive has to the Company, Parent or their affiliates, including, without limitation, under the Restrictive Covenants Agreement. In the event of any conflict between this Section 7(d) and any other such restrictive covenant, this Section 7(d) shall govern.

(e)Non-Disparagement. Subject to Section 10 of this Agreement, the Executive agrees not to take any action or make any statements (whether written, oral, through social or electronic media or otherwise) that are disparaging about or adverse to the business interests of the Company, Parent or any of the Releasees. The Executive further agrees not to take any actions or conduct himself in any way that would reasonably be expected to affect adversely the reputation or goodwill of the Company or any of the Releasees.

8.Continuing Obligations; Injunctive Relief. The Executive acknowledges that the Transition Benefits are conditioned on his full compliance with Section 7 of this Agreement and the Restrictive Covenants Agreement (collectively, the “Continuing Obligations”). In the event that the Executive fails to comply with any of the Continuing Obligations, then in addition to any other legal or equitable remedies it may have for such breach, the Company shall have the right to end the Transition Benefits. Such termination in the event of a breach by the Executive shall not affect the general release in Section 6 of this Agreement or the Executive’s obligation to comply with the Continuing Obligations. Further, the Executive agrees that any breach of the Continuing Obligations is likely to cause the Company substantial and irrevocable damage and therefore, in the event of such breach, the Company, in addition to such other remedies which may be available, will be entitled to specific performance and other injunctive relief, without the posting of a bond. If the Executive violates the Continuing Obligations, in addition to all other remedies available to the Company at law, in equity and under contract, the Executive agrees that the Executive is obligated to pay all the Company’s costs of enforcement of this Agreement, including reasonable attorneys’ fees and expenses.

9.Advice of Counsel. This Agreement is a legally binding document and the Executive’s signature will commit the Executive to its terms. The Company advises the Executive to consult with an attorney prior to signing this Agreement. The Executive acknowledges that he has carefully read and fully understands all of the provisions of this Agreement and that he is knowingly and voluntarily entering into this Agreement. In signing this Agreement, the Executive is not relying upon any promises or representations made by anyone at or on behalf of the Company.

with any federal agency or any state or local governmental agency or commission (together, a “Government Agency”); or (iii) ability to communicate with any Government Agency or otherwise participate in any investigation or proceeding that may be conducted by any Government Agency. If the Executive files any charge or complaint with any Government Agency and if the Government Agency pursues any claim on the Executive’s behalf, or if any other third party pursues any claim on the Executive’s behalf, the Executive waives any right to monetary or other individualized relief (either individually or as part of any collective or class action); provided that nothing in this Agreement limits any right the Executive may have to receive a whistleblower award or bounty for information provided to the Securities and Exchange Commission.

11.Time for Consideration; Effective Date. The Executive acknowledges that he has been given the opportunity to consider this Agreement for 21 days before executing it (the “Consideration Period”). To accept this Agreement, the Executive must return a signed, unmodified original or PDF copy of this Agreement so that it is received by the undersigned at or before the expiration of the Consideration Period. If the Executive signs this Agreement before the end of the Consideration Period, the Executive acknowledges that such decision was entirely voluntary and that the Executive had the opportunity to consider this Agreement for the entire Consideration Period. For the period of seven (7) business days from the date when the Executive signs this Agreement, the Executive has the right to revoke this Agreement by written notice to the undersigned, provided that such notice is delivered so that it is received at or before the expiration of the seven (7) business day revocation period. This Agreement shall not become effective or enforceable during the revocation period. This Agreement shall become effective on the first business day following the expiration of the revocation period (the “Effective Date”). Notwithstanding the foregoing, the Company may withdraw the offer of this Agreement or may void this Agreement before the Effective Date if the Executive breaches any provision contained in this Agreement (including any provision of the Restrictive Covenants Agreement).

12.Enforceability. If any portion or provision of this Agreement (including, without limitation, any portion or provision of any section of this Agreement) shall to any extent be declared illegal or unenforceable by a court of competent jurisdiction, then the remainder of this Agreement, or the application of such portion or provision in circumstances other than those as to which it is so declared illegal or unenforceable, shall not be affected thereby, and each portion and provision of this Agreement shall be valid and enforceable to the fullest extent permitted by law.

13.Entire Agreement. This Agreement, together with the Restrictive Covenants Agreement, constitutes the entire agreement between the parties concerning the subject matter of this Agreement, and supersedes and replaces any and all prior agreements and understandings between the parties concerning the subject matter hereof, including, without limitation, the Employment Agreement, provided that the Equity Documents (subject to the terms of this Agreement) and the Indemnification Agreement shall continue to be in full force and effect.

14.Waiver; Amendment. No waiver of any provision of this Agreement, including the Continuing Obligations, shall be effective unless made in writing and signed by the waiving party. The failure of either party to require the performance of any term or obligation of this Agreement or the Continuing Obligations, or the waiver by either party of any breach of this Agreement or the Continuing Obligations shall not prevent any subsequent enforcement of such term or obligation or be deemed a waiver of any subsequent breach. This Agreement may not be modified or amended except in a writing signed by both the Executive and a duly authorized officer of the Company.

16.Section 409A. To the extent that any payment or benefit described in this Agreement constitutes “non-qualified deferred compensation” under Section 409A of the Internal Revenue Code of 1986, as amended (the “Code”), and to the extent that such payment or benefit is payable upon the Executive’s termination of employment, then such payments or benefits shall be payable only upon the Executive’s “separation from service.” The determination of whether and when a separation from service has occurred shall be made in accordance with the presumptions set forth in Treasury Regulation Section 1.409A-l(h). The parties intend that this Agreement will be administered in accordance with Section 409A of the Code. To the extent that any provision of this Agreement is ambiguous as to its compliance with Section 409A of the Code, the provision shall be read in such a manner so that all payments hereunder comply with Section 409A of the Code. Each payment pursuant to this Agreement is intended to constitute a separate payment for purposes of Treasury Regulation Section 1.409A-2(b)(2). The parties agree that this Agreement may be amended, as reasonably requested by either party, and as may be necessary to fully comply with Section 409A of the Code and all related rules and regulations in order to preserve the payments and benefits provided hereunder without additional cost to either party. The Company makes no representation or warranty and shall have no liability to the Executive or any other person if any provisions of this Agreement are determined to constitute deferred compensation subject to Section 409A of the Code but do not satisfy an exemption from, or the conditions of, such Section.

21.Assignment; Successors and Assigns. Neither the Executive nor the Company may make any assignment of this Agreement or any interest in it, by operation of law or otherwise, without the prior written consent of the other; provided, however, that the Company may assign its rights and obligations under this Agreement (including the Restrictive Covenants Agreement) without the Executive’s consent to any affiliate or to any person or entity with whom the Company shall hereafter effect a reorganization or consolidation, into which the Company merges or to whom it transfers all or substantially all of its properties or assets. This Agreement shall inure to the

benefit of and be binding upon the Executive and the Company, and each of the Executive’s and the Company’s respective successors, executors, administrators, heirs and permitted assigns. In the event of the Executive’s death after the Executive’s termination of employment but prior to the completion by the Company of all payments due to the Executive under this Agreement, the Company shall continue such payments to the Executive’s beneficiary designated in writing to the Company prior to the Executive’s death (or to the Executive’s estate, if the Executive fails to make such designation).

22.Counterparts. This Agreement may be executed in any number of counterparts, each of which when so executed and delivered shall be taken to be an original; but such counterparts shall together constitute one and the same document. Delivery of an executed counterpart's signature page of this Agreement, by facsimile, electronic mail in portable document format (.pdf), or by any other electronic means intended to preserve the original graphic and pictorial appearance of a document, has the same effect as delivery of an executed original of this Agreement.
