This letter agreement (this “Agreement”) will set forth the terms of your “at-will” employment relationship
with Everbridge, Inc., and/or any present or future parent, subsidiary or affiliate thereof (collectively, the “Company”). This Agreement hereby supersedes any and all previous agreements relating to your employment relationship
with the Company. The terms of your position with the Company are as set forth below and will be effective only upon, and subject to, the signing of this Agreement and any other agreements or documentation required hereunder, by you and the
Company. 
 1. Employment. 

(a) Title and Duties. Subject to the terms and conditions of this Agreement, the Company will employ you and you will be employed by
the Company, on an “at-will” basis, as its Chief Executive Officer, or in such additional or different position or positions as the Board of Directors of the Company (the “Board”) may determine in its sole discretion,
reporting to the Board. You shall do and perform all services, acts or things necessary or advisable to manage and conduct the business of the Company and which are normally associated with the position of Chief Executive Officer, and as further
described in Schedule 1 attached hereto. 
 (b) Full Time Best Efforts. For so long as you are employed hereunder, you
will devote substantially all of your business time and energies to the business and affairs of the Company, and shall at all times faithfully, industriously and to the best of your ability experience and talent, perform all of your duties and
responsibilities hereunder. In furtherance of, and not in limitation of the foregoing, during the term of this Agreement you further agree that you shall not, with the exception of the · company or companies that are identified on
Schedule 2 attached hereto, if any, and subject to the provisions thereof render commercial or professional services of any nature, including as a founder, advisor, to any person or organization, whether or not for compensation,
without the prior approval of the Board, in its sole discretion; provided, however, that nothing contained in this Section l(b) will be deemed to prevent or limit (i) your right to manage your personal investments on your own personal time, or
(ii) your ability to serve as a member of the board of directors of up to four (4) companies that are not competitive with the business, products or services at any time offered, developed or marketed by the Company and/or its
subsidiaries. As set forth above, your employment with the Company is “at-will,” and, accordingly, either you or the Company may terminate your employment at any time, with or without cause, for any reason or no reason. 

(c) Location. Unless the parties hereto otherwise agree in writing, during the term of this Agreement, you shall perform the services
required to be performed pursuant to this Agreement at the Company’s Massachusetts offices, currently located in Waltham, Massachusetts; provided, however, that the Company may from time to time require you to travel temporarily to other
locations in connection with the Company’s business. 

 2. Compensation. During the term of your employment with the Company, the Company will pay
you the following compensation: 
 (a) Base Salary. As of the effective date of this Agreement, which shall be the date set
forth on the signature page hereof following the signature of the individual executing this Agreement on behalf of the Company (the “Effective Date”), you will be paid an annual salary as set forth on Schedule A
attached hereto, as may be increased from time to time as part of the Company’s normal salary review process (the “Base Salary”). The Base Salary shall be prorated for any partial year of employment on the basis of a 365-day
year. Your Base Salary will be subject to standard payroll deductions and withholdings, and payable in accordance with the Company’s standard payroll practice as it exists from time to time. 

(b) Expenses. During the term of your employment, the Company shall reimburse you for all reasonable and documented expenses incurred
by you in the performance of your duties under this Agreement in accordance with Company policy. 
 (c) Annual Performance Bonus. You
will be eligible to earn an annual performance bonus at the conclusion of each year of employment with the Company (the “Annual Bonus”). The amount, award and timing of the payment of the Annual Bonus shall be set forth in a Company
Management Incentive Plan, established each year by the Board, in its discretion. The Company’s Management Incentive Plan for fiscal year 2012 is set forth on Schedule A attached hereto. Company Management Incentive Plans, if any, for
subsequent years, shall be provided to you by the Board. 
 (d) Employee Benefits. As an employee of the Company, you will be
eligible to participate in such Company-sponsored benefits and programs as are made generally available by the Board to other employees of the Company. In addition, you will be entitled to paid vacation in accordance with the Company’s vacation
policy as established by the Board and as in effect from time to time. The Company reserves the right to change or eliminate any benefit plans at any time, upon notice to you. 

3. Separation Benefits. You shall be entitled to receive separation benefits upon termination of employment only as set forth in this
Section 3; provided, however, that in the event you are entitled to any severance pay under a Company-sponsored severance pay plan, any such severance pay to which you are entitled under such severance pay plan shall reduce the amount of
severance pay to which you are entitled pursuant to this Section 3. In all cases, upon termination of employment you will receive payment for all salary, earned bonus (if any) and unused vacation accrued as of the date of your termination of
employment, and your benefits will be continued under the Company’s then existing benefit plans and policies in accordance with such plans and policies in effect on the date of termination and in accordance with applicable law. In furtherance
of, and not in limitation of the foregoing, but without duplication, during the period wherein which you shall be receiving Separation Payments in accordance with the provisions of Section 3(d) hereof (the “Severance Period”),
then the Company shall, at its election, either (i) continue to pay for your health benefits under the Company’s sponsored health care program in which you were enrolled and eligible to receive benefits prior to your

 
termination of employment, or (ii) pay for your health coverage under the Consolidated Omnibus Budget Reconciliation Act (“COBRA”), in each case, for the Severance Period,
when such premiums are due and owing. 
 (a) Voluntary Resignation. If you voluntarily elect to terminate your employment with the
Company (other than under the circumstances described in Section 3(c) or 3(d) below), you shall not be entitled to any separation benefits. 

(b) Termination for Cause. If the Company or its successor terminates your employment for Cause (as defined below), then you shall not
be entitled to receive any separation benefits. 
 (c) Termination for Death or Disability. If your employment with the Company is
terminated by reason of death or Disability, then, as a severance benefit, the Company shall continue to pay one-twelfth (1/12th) of your Base Salary for a period of six (6) months, in
accordance with the Company’s normal payroll schedule and policy in effect from time to time. For purposes of this section, “Disability” shall mean: your inability to perform your duties under this Agreement because you have
become permanently disabled within the meaning of any policy of disability income insurance covering employees of the Company then in force. In the event the Company has no policy of disability income insurance covering employees of the Company in
force when you become disabled, the term “Disability” shall mean your inability to perform your duties under this Agreement by reason of any incapacity, physical or mental, which the Board, based upon medical advice or an opinion
provided by a licensed physician acceptable to the Board, determines to have incapacitated you from satisfactorily performing all of your usual services for the Company for a period of at least ninety (90) days during any twelve (12) month
period (whether or not consecutive) and is expected to continue to incapacitate you thereafter, not including any time during which you were on medical leave required by federal or state law. Based upon such medical advice or opinion, the
determination of the Board shall be final and binding and the date such determination is made shall be the date of such Disability for purposes of this Agreement. 

(d) Involuntary Termination; Termination for Good Reason. Subject to the provisions of Section 6 hereof, if either (i) your
employment is terminated by the Company other than for Cause, or (ii) you voluntarily terminate your employment with the Company for Good Reason (as defined below), in either case, then, as a severance benefit, the Company shall continue to pay
you an amount equal to one-twelfth (1/12th) of your Base Salary for twelve (12) months. Payment of amounts set forth in this Section 3(d) shall be paid to you monthly, in accordance
with the Company’s normal payroll schedule and policy in effect from time to time. 
 (e) Certain Definitions. For purposes of
this Agreement, the following terms shall have the following meanings: 
 (i) “Cause” shall mean any
of the following: (i) acts of moral turpitude, fraud or dishonesty that involve the assets of the Company, its customers, suppliers or affiliates; (ii) the conviction of, or a pleading of guilty or nolo contendere to, a felony other
than involving a traffic related infraction; (iii) use of narcotics, liquor or illicit drugs in a manner that has had a detrimental effect on the performance of your duties; (iv) willfully and repeatedly neglecting your duties to the
Company; (v) engaging in any conduct which, after an investigation by a neutral third party, is determined to be discriminatory or harassing toward other Company employees; or (vi) engaging in any conduct which breaches a material
provision of this Agreement or the Inventions Agreement (as defined below). 

 (A) Cause shall only exist where the Company has provided you with written notice of the alleged
problem or violation of this Agreement or the Inventions Agreement, and you shall have failed to cure such condition to the reasonable satisfaction of the Company within ten (10) business days. In making any determination that Cause exists, the
Board shall act fairly and in good faith and shall give you an opportunity to appear and be heard at a meeting of the Board or any committee thereof and present evidence on your behalf. For any termination pursuant to (e)(i)(i) or (e)(i)(vi) of
Section 3, the Company must have reasonable, specific evidence to establish that such conduct has occurred or “Cause” shall not exist. For the avoidance of doubt, and notwithstanding anything herein contained to the contrary, in the
event that (x) any of the conditions specified in Section (e)(i)(i) through (e)(i)(vi) of Section 3 shall have occurred, and (y) the Company has reasonable evidence to establish that such conduct has occurred, and (z) the
occurrence of any such event shall not be capable of cure, then the Company shall not be required to provide you any notice and a cure period in respect thereof. 

(ii) “Change in Control” shall mean (x) the sale, lease, assignment, transfer, conveyance or disposal of all or
substantially all of the assets of the Company, (y) the exclusive license of all or substantially all of the material intellectual property rights of the Company, or (z) the acquisition of the Company by means of consolidation, corporate
reorganization, merger or other transaction or series of related transactions in which stockholders of the Company immediately prior to such transaction(s) do not own at least a majority of the outstanding voting securities of the successor entity
(in each case, other than in connection with a financing transaction primarily for the purposes of raising working capital, or a reincorporation of the Company into another jurisdiction). 

(iii) “Good Reason” shall mean (A) your demotion to a position with the Company or any successor thereto that
does not include the same level of responsibilities without your consent, (B) a material breach by the Company of its contractual obligations to you that continues for ten (10) business days after your written notice to the Company,
(C) a material reduction in your Base Salary of more than ten percent (10%) or a material reduction in your benefits, without your written consent, other than a reduction in salary or benefits with respect to similarly situated employees
of the Company generally, or (D) the relocation, without your written consent, of your principal workplace to a geographic location that is more than fifty (50) miles from the Company’s place of business in Waltham, Massachusetts.

 (iv) “Taxes” shall mean all Federal and state taxes. 

4. Restricted Stock. As soon as practicable following the Effective Date, you shall be issued Seven Million, Seven Hundred Seventy
Thousand, Three Hundred Sixty One (7,770,361) shares of common stock of the Company (the “Shares”), as more fully set forth in the Restricted Stock Award Agreement attached hereto as Schedule A-1 and incorporated
herein by this reference (the “Award Agreement”); provided, however, that the issuance of such Shares shall be subject to, and conditioned upon your execution thereof and delivery to the Company as therein contemplated. In
the event that, within twelve (12) months following the grant to you of the Shares, the Company shall consummate a transaction constituting a Change in Control, then the Company shall pay to you an amount equal to the difference between
(i) the amount of the federal and state taxes (“Taxes”) that you will actually have to pay, in respect of the net proceeds received by you at the closing of the transaction constituting a Change in Control (the
“Proceeds”) for such · hares, and (ii) the amount of 

 
the Taxes that you would otherwise have actually had to pay in connection with the receipt of the Proceeds (such amount, the “Tax Differential Payment”), had you owned such
Shares for at least twelve (12) months prior to the consummation of such transaction constituting a Change in Control. In addition thereto, the Company shall pay to you the actual amount of the Taxes you will have to pay as a result of your
receipt of the Tax Differential Payment (the “Gross Up Payment” and together with the Tax Differential Payment the “Additional Payment”). With respect to the Additional Payment, (x) the determination of such
amounts hall be determined by the Company in its good faith judgment in consultation with its independent auditors, which such determination shall be final and binding on you· and (y) payment of such Additional Payment shall be made, at
the election of the Company, either concurrently with, or a soon as practicable following, the Change in Control but in no event later than ninety (90) days following the date of such Change in Control. 

5. Mitigation. You shall not be required to mitigate the amount of any payment or benefits provided for in this Agreement by seeking
other employment or otherwise. Further, the amount of any payment or benefits provided for in this Agreement shall not be reduced by any compensation earned by you as a result of employment by another employer, by retirement benefits, by offset
against any amount claimed to be owed by you to the Company or otherwise. 
 6. Conditions to Receipt of Severance or other Benefits
Pursuant to this Agreement. 
 (a) Release of Claims Agreement. Notwithstanding anything herein contained to the contrary, the
receipt of any severance or other benefits pursuant to Section 3(d) of this Agreement (the “Separation Payments”) is subject to your signing and not revoking a separation agreement and release of claims, based on the
Company’s standard form release, of any and all claims you may have against the Company and its officers, employees, directors, parents and affiliates, in substantially the form attached hereto on
Schedule A-2 (the “Release”), which must become effective and irrevocable no later than the sixtieth (60th) day following the termination of employment (the
“Release Deadline”). If the Release does not become effective and irrevocable by the Release Deadline, you will forfeit any rights to Separation Payments or benefits under this Agreement. No Separation Payments and benefits under
this Agreement will be paid or provided until the Release becomes effective and irrevocable, and any such Separation Payments and benefits otherwise payable between the date of your termination of employment and the date the Release becomes
effective and irrevocable will be paid on the date the Release becomes effective and irrevocable. 
 (b) Continued Compliance with
Agreements. Your receipt of any Separation Payments or other benefits pursuant to this Agreement will be subject to, and contingent upon, your not being in breach of this Agreement, the Inventions Agreement as of the date of your termination,
and your continued compliance following the date of your termination with the terms of this Agreement, the Inventions Agreement and Release, notwithstanding anything herein contained to the contrary. 

(c) Section 409A. 

(i) Notwithstanding anything to the contrary in this Agreement, no severance pay or benefits to be paid or provided to you, if any, pursuant
to this Agreement that, when considered together with any other severance payments or separation benefits, are considered deferred compensation under Internal Revenue Code Section 409A (together, the “Deferred Payments”) will
be payable until you have a “separation from service” within the meaning of Section 409A (“Section 409A”) of the Internal Revenue Code of 1986, as amended (the “Code”). Similarly, no severance

 
payable to you, if any, pursuant to this Agreement that otherwise would be exempt from Section 409A pursuant to Treasury Regulation Section 1.409A 1(b)(9) will be payable until you have
a “separation from service” within the meaning of Section 409A. 
 (ii) Any severance payments or benefits under this
Agreement that would be considered Deferred Payments will be paid on, or, in the case of installments, will not commence until, the sixtieth (60th) day following your separation from service, or, if later, such time as required by
Section 6(c)(iii). Except as required by Section 6(c)(iii), any installment payments that would have been made to you during the sixty (60) day period immediately following your separation from service but for the preceding sentence
will be paid to you on the sixtieth (60th) day following your separation from service and the remaining payments will be made as provided in this Agreement. 

(iii) Further, if you are a “specified employee” within the meaning of Section 409A at the time of your separation from
service (other than due to death), any Deferred Payments that otherwise are payable within the first six (6) months following your separation from service will become payable on the first payroll date that occurs on or after the date six
(6) months and one (1) day following the date of your separation from service. All subsequent Deferred Payments, if any, will be payable in accordance with the payment schedule applicable to each payment or benefit. Notwithstanding
anything herein to the contrary, in the event of your death following your separation from service but prior to the six (6) month anniversary of your separation from service (or any later delay date), then any payments delayed in accordance
with this Section 6(c)(iii) will be payable in a lump sum as soon as administratively practicable after the date of your death and all other Deferred Payments will be payable in accordance with the payment schedule applicable to each payment or
benefit. Each payment and benefit payable under the Agreement is intended to constitute a separate payment for purposes of Section 1.409A-2(b)(2) of the Treasury Regulations. 

(iv) Any amount paid under this Agreement that satisfies the requirements of the “short-term deferral” rule set forth in
Section 1.409A-1(b)(4) of the Treasury Regulations will not constitute Deferred Payments for purposes of clause (i) above. Any amount paid under this Agreement that qualifies as a payment made as a result of an involuntary separation from
service pursuant to Section 1.409A-1(b)(9)(iii) of the Treasury Regulations that does not exceed the Section 409A Limit (as defined below) will not constitute Deferred Payments for purposes of clause (i) above. 

(v) The foregoing provisions are intended to comply with, or be exempt from, the requirements of Section 409A so that none of the
severance payments and benefits to be provided under this Agreement will be subject to the additional tax imposed under Section 409A, and any ambiguities herein will be interpreted to so comply or be exempt. You and the Company agree to work
together in good faith to consider amendments to this Agreement and to take such reasonable actions which are necessary, appropriate or desirable to avoid imposition of any additional tax or income recognition prior to actual payment to you under
Section 409A. In no event will the Company reimburse you for any taxes that may be imposed on you as result of Section 409A. 
 7.
Confidential and Proprietary Information. 
 (a) Proprietary Information and Inventions Agreement. As a condition to the
execution and effectiveness of this Agreement, you agree to execute concurrently herewith, and to abide by, the Company’s Proprietary Information and Inventions Agreement, attached hereto as Schedule B (the “Inventions
Agreement”). In furtherance, and not in limitation of the provisions thereof, you agree, during the term hereof and thereafter, that you shall take all steps reasonably 

 
necessary to hold the Company’s proprietary information in trust and confidence, will not use proprietary information in any manner or for any purpose not expressly set forth in this
Agreement, and will not (other than in the performance of the services to the Company as herein contemplated), disclose any such proprietary information to any third party without first obtaining the Company’s express written consent on a
case-by-case basis. 
 (b) Third Party Information. You understand that the Company has received, and will in the future receive,
from third parties confidential or proprietary information (“Third Party Information”) subject to a duty on the Company’s part to maintain the confidentiality of such information and use it only for certain limited purposes.
You agree to hold Third Party Information in confidence and not to disclose to anyone (other than the Company’s personnel who need to know such information in connection with their work for the Company) or to use, except in connection with the
performance of your services to the Company, Third Party Information unless expressly authorized in writing by an officer of the Company. 

8. Arbitration of Disputes; Voluntary Nature of Agreement. 

(a) Arbitration. Except as provided for any action arising out of any violation of the Inventions Agreement or any excluded claims and
remedies under state law, you and the Company both agree that any disputes of any kind whatsoever arising out of or relating to the termination of your employment with the Company, including any breach of this Agreement, shall be subject to final
and binding arbitration, in any forum and form agreed upon by the parties or, in the absence of such an agreement, under the auspices of the American Arbitration Association (“AAA”) in Boston, Massachusetts in accordance with the
Employment Dispute Resolution Rules of the AAA, including, but not limited to, the rules and procedures applicable to the selection of arbitrators. Judgment upon the award rendered by the arbitrator may be entered in any court having jurisdiction
thereof. This Section 8 shall be specifically enforceable. Notwithstanding the foregoing, this Section 8 shall not preclude either party from pursuing a court action for the sole purpose of obtaining a temporary restraining order or a
preliminary injunction in circumstances in which such relief is appropriate; provided that any other relief shall be pursued through an arbitration proceeding pursuant to this Section 8. You further understand that this Agreement to arbitrate
also applies to any disputes that the Company may have with you relating to or arising from, the termination of your employment with the Company, except for any action arising out of the Inventions Agreement. 

(b) Voluntary Nature of Agreement. You acknowledge and agree that you are executing this Agreement voluntarily and without any duress
or undue influence by the Company or anyone else. You further acknowledge and agree that you have carefully read this Agreement and have asked any questions needed for you to understand the terms, consequences, and binding effect of this Agreement
and fully understand it, including that you are waiving your right to a jury trial. Finally, you acknowledge that you have been advised by the Company to seek the advice of an attorney of your choice before signing this Agreement and
you agree that you have been provided such an opportunity. 
 9. General. 

(a) Entire Agreement, Amendment and Waiver. This Agreement, together with the other agreements specifically referred to herein,
embodies the entire agreement and understanding between the parties hereto with respect to the subject matter hereof and supersedes all prior oral or written agreements and understandings relating to the subject matter hereof. The terms and
provisions of this Agreement may be modified or amended only by written agreement executed by the parties 

 
hereto. The terms and provisions of this Agreement may be waived, or consent for the departure therefrom granted, only by written document executed by the party entitled to the benefits of such
terms or provisions. Each such waiver or consent will be effective only in the specific instance and for the purpose for which it was given, and will not constitute a continuing waiver or consent. 

(b) Notices. Any notice, request, instruction or other document required or permitted hereunder shall be in writing and shall be deemed
effectively given: (a) upon personal delivery to the party to be notified; (b) three (3) days after having been sent by registered or certified mail, return receipt requested, postage prepaid; or (c) one (1) business day
after deposit with a nationally recognized overnight courier, specifying next day delivery, with written verification of receipt. All communications shall be sent to the party to be notified at the following address of such party or at such other

contrary herein contained, any party may petition a court for injunctive relief where either party alleges or claims a violation of this Agreement or the Inventions Agreement or any other agreement regarding trade secrets, confidential information
or nonsolicitation. In the event either party seeks injunctive relief, the prevailing party shall be entitled to recover reasonable costs and attorneys fees. 

(d) Assignment. The Company may assign its rights and obligations hereunder to any person or entity that succeeds to all or
substantially all of the Company’s business or that aspect of the Company’s business in which you are principally involved. You may not assign your rights and obligations under this Agreement without the prior written consent of the

and other taxes.

invalidity or illegality of any provision of this Agreement shall not render any 

 
other provision of this Agreement unenforceable, invalid or illegal. Such arbitrator or court shall have the authority to modify or replace the invalid or unenforceable term or provision with a
valid and enforceable term or provision which most accurately represents the parties’ intention with respect to the invalid or unenforceable term or provision. If moreover, any one or more of the provisions contained in this Agreement will for
any reason be held to be excessively broad as to duration, geographic scope, activity or subject, it will be construed by limiting and reducing it, so as to be enforceable to the extent compatible with the applicable law as it will then appear.

Agreement) of the Company. 
 (j) Survival. The provisions of Sections 1(d), 3, 6, 7, 8 and 9, and the provisions of the Inventions
Agreement, shall survive termination of this Agreement.

policies. 
 (l) Confirmation of Employment Status. Prior to your first day of employment with the Company, and as a condition to
such employment, you shall provide the Company with documentation of your eligibility to work in the United States, as required by the Immigration and Reform and Control Act of 1986.

Kenneth S. Goldman 
  

	 	Re:	Terms of Employment  

 Dear Kenneth: 

This letter agreement (this “Agreement”) will set forth the terms of your “at-will” employment relationship with
Everbridge, Inc., and/or any present or future parent, subsidiary or affiliate thereof (collectively, the “Company”). This Agreement hereby supersedes any and all previous agreements relating to your employment relationship with the
Company. The terms of your position with the Company are as set forth below and will be effective only upon, and subject to, the signing of this Agreement and any other agreements or documentation required hereunder, by you and the Company. 

1. Employment. 
 (a)
Title and Duties. Subject to the terms and conditions of this Agreement, the Company will employ you, and you will be employed by the Company, on an “at-will” basis, as its Senior Vice President and Chief Financial Officer, or in
such additional or different position or positions as the Board of Directors of the Company (the “Board”) may determine in its sole discretion, reporting to Jaime Ellertson, Chief Executive Officer. You shall do and perform all
services, acts or things necessary or advisable to manage and conduct the business of the Company and which are normally associated with the position of Senior Vice President and Chief Financial Officer, and as further described in Schedule 1
attached hereto. 
 (b) Full Time Best Efforts. For so long as you are employed hereunder, you will devote substantially all of your
business time and energies to the business and affairs of the Company, and shall at all times faithfully, industriously and to the best of your ability, experience and talent, perform all of your duties and responsibilities hereunder. In furtherance
of, and not in limitation of the foregoing, during the term of this Agreement, you further agree that you shall not, with the exception of the company or companies that are identified on Schedule 2 attached hereto, if any, and subject to the
provisions thereof, render commercial or professional services of any nature, including as a founder, advisor, or a member of a board of directors, to any person or organization, whether or not for compensation, without the prior approval of the
Chief Executive Officer in his sole discretion; provided, however, that nothing contained in this Section 1(b) will be deemed to prevent or limit your right to manage your personal investments on your own personal time. As set forth above, your
employment with the Company is “at-will,” and, accordingly, either you or the Company may terminate your employment at any time, with or without cause, for any reason or no reason. 

  
 1

accelerate; (i) for the number of shares equal to the number of months of full-time employment as of the date of a change of control divided by forty eight (i.e., number of months of employment divided by 48), as well as, (ii) the
additional amount of 50% of all of your unvested (as of the date of a Change of Control after the acceleration granted in (i) above) options shall vest in full subject to the company’s standard Change of Control language for its senior

 2 

 
(i) and (ii) above as part of the Change of Control or does not offer equivalently valued new options and incentives to you, then 100% of your remaining unvested share options will vest in
full immediately prior to consumption of the Change of Control. 
 (e) Employee Benefits. As an employee of the Company, you will be
eligible to participate in such Company-sponsored benefits and programs as are made generally available by the Board to other employees of the Company. In addition, you will be entitled to annually accrue four (4) weeks of Paid Time Off
(vacation/sick time) in accordance with the Company’s vacation policy as established by the Board and as in effect from time to time. The Company reserves the right to change or eliminate any benefit plans at any time, upon notice to you. 

3. Separation Benefits. You shall be entitled to receive separation benefits upon termination of employment only as set forth in this
Section 3; provided, however, that in the event you are entitled to any severance pay under a Company-sponsored severance pay plan, any such severance pay to which you are entitled under such severance pay plan shall reduce the amount of
severance pay to which you are entitled pursuant to this Section 3. In all cases, upon termination of employment you will receive payment for all salary, earned bonus (if any) and unused vacation accrued as of the date of your termination of
employment, and your benefits will be continued under the Company’s then existing benefit plans and policies in accordance with such plans and policies in effect on the date of termination and in accordance with applicable law. In furtherance
of, and not in limitation of the foregoing, but without duplication, during the period wherein which you shall be receiving Separation Payments in accordance with the provisions of Section 3(d) hereof (the “Severance Period”),
then the Company shall, at its election, either (i) continue to pay for your health benefits under the Company’s sponsored health care program in which you were enrolled and eligible to receive benefits prior to your termination of
employment, or (ii) pay for your health coverage under the Consolidated Omnibus Budget Reconciliation Act (“COBRA”), in each case, for the Severance Period, when such premiums are due and owing.

described in Section 3(c) or 3(d) below), you shall not be entitled to any separation benefits. 
 (b) Termination for Cause. If
the Company or its successor terminates your employment for Cause (as defined below), then you shall not be entitled to receive any separation benefits.

severance benefit, the Company shall continue to pay one-twelfth (1/12th) of your Base Salary for a period of three (3) months, in accordance with the Company’s normal payroll
schedule and policy in effect from time to time. For purposes of this section, “Disability” shall mean your inability to perform your duties under this Agreement because you have become permanently disabled within the meaning of any
policy of disability income insurance covering employees of the Company then in force. In the event the Company has no policy of disability income insurance covering employees of the Company in force when you become disabled, the term
“Disability” shall mean your inability to perform your duties under this Agreement by reason of any incapacity, physical or mental, which the Board, based upon medical advice or an opinion provided by a licensed physician acceptable
to the Board, 

  
 3 

 
determines to have incapacitated you from satisfactorily performing all of your usual services for the Company for a period of at least ninety (90) days during any twelve (12) month
period (whether or not consecutive) and is expected to continue to incapacitate you thereafter, not including any time during which you were on medical leave required by federal or state law. Based upon such medical advice or opinion, the
determination of the Board shall be final and binding and the date such determination is made shall be the date of such Disability for purposes of this Agreement. 

(d) Involuntary Termination; Termination for Good Reason. Subject to the provisions of Section 5 hereof, if either (i) your
employment is terminated by the Company other than for Cause, or (ii) you voluntarily terminate your employment with the Company for Good Reason (as defined below), in either case, then, as a severance benefit, the Company shall continue to pay
you an amount equal to one-twelfth (1/12th) of your Base Salary for without duplication, the following time period: (A) three (3) months, if and to the extent that your employment is terminated within twelve (12) months following
the Effective Date; or (B) six (6) months, if and to the extent that your employment is terminated more than twelve (12) months following the Effective Date. Payment of amounts set forth in this Section 3(d) shall be paid to you
monthly, in accordance with the Company’s normal payroll schedule and policy in effect from time to time. 
 (e) Certain
Definitions. For purposes of this Agreement, the following terms shall have the following meanings: 
 (i) “Cause”
shall mean any of the following: (i) acts of moral turpitude, fraud or dishonesty that involve the assets of the Company, its customers, suppliers or affiliates; (ii) the conviction of, or a pleading of guilty or nolo contendere to,

provided you with written notice of the alleged problem or violation of this Agreement or the Inventions Agreement, and you shall have failed to cure such condition to the reasonable satisfaction of the Company within ten (10) business days. In
making any determination that Cause exists, the Board shall act fairly and in good faith and shall give you an opportunity to appear and be heard at a meeting of the Board or any committee thereof and present evidence on your behalf. For any
termination pursuant to (e)(i)(i) or (e)(i)(vi) of Section 3, the Company must have reasonable, specific evidence to establish that such conduct has occurred or “Cause” shall not exist. For the avoidance of doubt, and
notwithstanding anything herein contained to the contrary, in the event that (x) any of the conditions specified in Section (e)(i)(i) through (e)(i)(vi) of Section 3 shall have occurred, and (y) the Company has reasonable evidence to
establish that such conduct has occurred, and (z) the occurrence of any such event shall not be capable of cure, then the Company shall not be required to provide you any notice and a cure period in respect thereof. 

(ii) “Change in Control” shall mean (x) the sale, lease, assignment, transfer, conveyance or disposal of all or
substantially all of the assets of the Company, (y) the 

  
 4 

 
exclusive license of all or substantially all of the material intellectual property rights of the Company, or (z) the acquisition of the Company by means of consolidation, corporate
reorganization, merger or other transaction or series of related transactions in which stockholders of the Company immediately prior to such transaction(s) do not own at least a majority of the outstanding voting securities of the successor entity
(in each case, other than in connection with a financing transaction primarily for the purposes of raising working capital, or a reincorporation of the Company into another jurisdiction). 

(iii) “Good Reason” shall mean (A) your demotion to a position with the Company or any successor thereto that does not
include the same level of responsibilities without your consent, (B) a material breach by the Company of its contractual obligations to you that continues for ten (10) business days after your written notice to the Company, (C) a

Company generally, or (D) the relocation, without your written consent, of your principal workplace to a geographic location that is more than fifty (50) miles from the Company’s place of business in Burlington, Massachusetts. 

4. Mitigation. You shall not be required to mitigate the amount of any payment or benefits provided for in this Agreement by seeking
other employment or otherwise. Further, the amount of any payment or benefits provided for in this Agreement shall not be reduced by any compensation earned by you as a result of employment by another employer, by retirement benefits, by offset
against any amount claimed to be owed by you to the Company or otherwise. 
 5. Conditions to Receipt of Severance or other Benefits
Pursuant to this Agreement. 
 (a) Release of Claims Agreement. Notwithstanding anything herein contained to the contrary, the
receipt of any severance or other benefits pursuant to Section 3(d) of this Agreement (the “Separation Payments”) is subject to your signing and not revoking a separation agreement and release of claims, based on the
Company’s standard form release, of any and all claims you may have against the Company and its officers, employees, directors, parents and affiliates, in substantially the form attached hereto on Schedule A-1 (the
“Release”), which must become effective and irrevocable no later than the sixtieth (60th) day following the termination of employment (the “Release
Deadline”). If the Release does not become effective and irrevocable by the Release Deadline, you will forfeit any rights to Separation Payments or benefits under this Agreement. No Separation Payments and benefits under this Agreement will
be paid or provided until the Release becomes effective and irrevocable, and any such Separation Payments and benefits otherwise payable between the date of your termination of employment and the date the Release becomes effective and irrevocable
will be paid on the date the Release becomes effective and irrevocable. 
 (b) Continued Compliance with Agreements. Your receipt of
any Separation Payments or other benefits pursuant to this Agreement will be subject to, and contingent upon, your not being in breach of this Agreement, the Inventions Agreement as of the date of your termination, and your continued compliance
following the date of your termination with the terms of this Agreement, the Inventions Agreement and Release, notwithstanding anything herein contained to the contrary. 

  
 5 

 (c) Section 409A. 

(i) Notwithstanding anything to the contrary in this Agreement, no severance pay or benefits to be paid or provided to you, if any, pursuant
to this Agreement that, when considered together with any other severance payments or separation benefits, are considered deferred compensation under Internal Revenue Code Section 409A (together, the “Deferred Payments”) will
be payable until you have a “separation from service” within the meaning of Section 409A (“Section 409A”) of the Internal Revenue Code of 1986, as amended (the “Code”). Similarly, no severance payable
to you, if any, pursuant to this Agreement that otherwise would be exempt from Section 409A pursuant to Treasury Regulation Section 1.409A 1(b)(9) will be payable until you have a “separation from service” within the meaning of
Section 409A. 
 (ii) Any severance payments or benefits under this Agreement that would be considered Deferred Payments will be paid
on, or, in the case of installments, will not commence until, the sixtieth (60th) day following your separation from service, or, if later, such time as required by Section 5(c)(iii). Except as required by Section 5(c)(iii), any
installment payments that would have been made to you during the sixty (60) day period immediately following your separation from service but for the preceding sentence will be paid to you on the sixtieth (60th) day following your
separation from service and the remaining payments will be made as provided in this Agreement. 
 (iii) Further, if you are a
“specified employee” within the meaning of Section 409A at the time of your separation from service (other than due to death), any Deferred Payments that otherwise are payable within the first six (6) months following your
separation from service will become payable on the first payroll date that occurs on or after the date six (6) months and one (1) day following the date of your separation from service. All subsequent Deferred Payments, if any, will be
payable in accordance with the payment schedule applicable to each payment or benefit. Notwithstanding anything herein to the contrary, in the event of your death following your separation from service but prior to the six (6) month anniversary
of your separation from service (or any later delay date), then any payments delayed in accordance with this Section 5(c)(iii) will be payable in a lump sum as soon as administratively practicable after the date of your death and all other
Deferred Payments will be payable in accordance with the payment schedule applicable to each payment or benefit. Each payment and benefit payable under the Agreement is intended to constitute a separate payment for purposes of
Section 1.409A-2(b)(2) of the Treasury Regulations. 
 (iv) Any amount paid under this Agreement that satisfies the requirements of
the “short-term deferral” rule set forth in Section 1.409A-1(b)(4) of the Treasury Regulations will not constitute Deferred Payments for purposes of clause (i) above. Any amount paid under this Agreement that qualifies as a
payment made as a result of an involuntary separation from service pursuant to Section 1.409A-1(b)(9)(iii) of the Treasury Regulations that does not exceed the Section 409A Limit (as defined below) will not constitute Deferred Payments for
purposes of clause (i) above. 
 (v) The foregoing provisions are intended to comply with, or be exempt from, the requirements of
Section 409A so that none of the severance payments and benefits to be provided under this Agreement will be subject to the additional tax imposed under Section 409A, 

  
 6 

 
and any ambiguities herein will be interpreted to so comply or be exempt. You and the Company agree to work together in good faith to consider amendments to this Agreement and to take such
reasonable actions which are necessary, appropriate or desirable to avoid imposition of any additional tax or income recognition prior to actual payment to you under Section 409A. In no event will the Company reimburse you for any taxes that
may be imposed on you as result of Section 409A. 
 6. Confidential and Proprietary Information. 

(a) Confidential Information and Inventions Agreement. As a condition to the execution and effectiveness of this Agreement, you agree
to execute concurrently herewith, and to abide by, the Company’s Confidential Information and Inventions Agreement, attached hereto as Schedule B (the “Inventions Agreement”). In furtherance, and not in limitation
of the provisions thereof, you agree, during the term hereof and thereafter, that you shall take all steps reasonably necessary to hold the Company’s proprietary information in trust and confidence, will not use proprietary information in any
manner or for any purpose not expressly set forth in this Agreement, and will not (other than in the performance of the services to the Company as herein contemplated), disclose any such proprietary information to any third party without first
obtaining the Company’s express written consent on a case-by-case basis. 
 (b) Third Party Information. You understand that the
Company has received, and will in the future receive, from third parties confidential or proprietary information (“Third Party Information”) subject to a duty on the Company’s part to maintain the confidentiality of such
information and use it only for certain limited purposes. You agree to hold Third Party Information in confidence and not to disclose to anyone (other than the Company’s personnel who need to know such information in connection with their work
for the Company) or to use, except in connection with the performance of your services to the Company, Third Party Information unless expressly authorized in writing by an officer of the Company. 

7. Arbitration. 
 (a)
Agreement to Arbitrate. Except as provided for any action arising out of any violation of the Inventions Agreement or as set forth in Section 7(b) below addressing excluded claims and remedies, you and the Company both agree that any
disputes of any kind whatsoever arising out of or relating to the termination of your employment with the Company, “including any breach of this Agreement, shall be subject to final and binding arbitration. 

(b) Excluded Claims, Relief and Enforcement. You understand that this Agreement does not prohibit you from pursuing an administrative
claim with a local, state, or federal administrative body such as the Department of Fair Employment and Housing, the Equal Employment Opportunity Commission, the National Labor Relations Board, or the Workers’ Compensation Board, or the
Employment Development Department for unemployment benefits. This Agreement does not preclude the Company from pursuing court action regarding any claims arising out of any breach of the Inventions Agreement or other claims not otherwise resulting
from, or arising out of, the termination of your employment with the Company. Nothing in this Agreement prohibits either party from seeking injunctive or declaratory relief from a court of competent jurisdiction. Either the Company or you may bring
an action in court to compel 

  
 7 

 
arbitration under this Agreement and to enforce an arbitration award. Otherwise, with the exception of claims set forth in this Section 7(b) or arising out of the Inventions Agreement,
neither party shall initiate or prosecute any lawsuit or claim in anyway related to any arbitrable claim, including without limitation any claims as to the making, existence, validity, or enforceability of the agreement to arbitrate. 

(c) Procedure. Employee agrees that any arbitration will be administered by Judicial Arbitration & Mediation Services, Inc.
(“JAMS”), pursuant to its employment arbitration rules and procedures (the “JAMS Rules”), a copy of which is attached as Schedule C to this Agreement and which are available at
www.jamsadr.com/rules-employment-arbitration. A neutral and impartial arbitrator shall have the power to decide any motions brought by any party to the arbitration, including motions for summary judgment and/or adjudication, motions to dismiss and
demurrers, and motions related to discovery, prior to any arbitration hearing. You also agree that the arbitrator shall have the power to award any remedies available under applicable law. In the event that either party to this Agreement rejects a
written offer to compromise from the other party, and fails to obtain a more favorable judgment or award, the arbitrator may award attorneys’ fees and costs to the party that made the offer to compromise in an amount that the arbitrator deems
appropriate, taking into consideration the attorneys’ fees and costs (including expert fees) actually incurred and reasonably necessary to defend or prosecute the action. The arbitrator will not have the authority to disregard or refuse to
enforce any lawful Company policy, and the arbitrator shall not order or require the Company to adopt a policy not otherwise required by law. You understand that the Company will pay the costs and fees of the arbitration that you initiate, but only
those fees over and above the costs you would have incurred had you filed a complaint in a court of law. You agree that the arbitrator shall prepare a written decision containing the essential findings and conclusions on which the award is based.
You agree that any arbitration under this Agreement shall be conducted in Los Angeles, California. 
 (d) Exclusive and Final Remedy.
Except as provided by the rules and this Agreement, arbitration shall be the sole, exclusive and final remedy for any dispute between you and the Company. Accordingly, except as provided for by the rules and this Agreement, neither you nor the
Company will be permitted to pursue court action regarding claims that are subject to arbitration. Nothing in this Agreement or in this provision is intended to waive the provisional relief remedies available under the rules. 

(e) Prohibition of Group Actions. Claims must be brought in your individual capacity, not as a representative or class member in any
purported class or representative proceeding. The arbitrator shall not consolidate claims of different employees into one proceeding, nor shall the arbitrator have the power to hear arbitration as a class action. In addition to waiving your right to
participate in class action arbitration, you also waive your right to bring claims pursuant to the Private Attorney General Act of 2004 (“PAGA”), codified in California Labor Code § 2698, et seq. or in a Private Attorney
General capacity. 
 (f) Voluntary Nature of Agreement. You acknowledge and agree that you are executing this Agreement voluntarily
and without any duress or undue influence by the Company or anyone else. You further acknowledge and agree that you have carefully read this Agreement and have asked any questions needed for you to understand the terms, consequences, and binding
effect of this Agreement and fully understand it, including that you are waiving your right to a 

  
 8 

 
jury trial. Finally, you acknowledge that you have been advised by the Company to seek the advice of an attorney of your choice before signing this Agreement and you agree that you
have been provided such an opportunity. 
 8. General.
