 2.        Term of
Agreement. This Agreement, and all rights and obligations of the parties hereunder, shall take effect upon the Effective Date and shall expire first to occur of (a) if neither a termination of the Executive’s employment with the
Company described in Section 4.1(a) below nor a Change in Control has occurred during the Term (as defined below), the expiration of the Term, (b) if a termination of the Executive Employment with the Company described in
Section 4.1(a) below occurs during the Term or within twenty-four (24) months following a Change in Control, the fulfillment by the Company of all of its obligations under Sections 4 and 5.2 and 5.3 or (c) if a Change in Control

(24) months following the Change in Control Date, the fulfillment by the Company of all of its obligations under Sections 4 and 5.2 and 5.3. “Term” shall mean the period commencing as of the Effective Date and continuing in
effect through March 23, 2019. 
 3.        Employment Status; Termination of
Employment. 
 3.1      Not an Employment Contract. The Executive acknowledges that this Agreement
does not constitute a contract of employment or impose on the Company any obligation to retain the Executive as an employee and that this Agreement does not prevent the Executive from terminating employment at any time. If the Executive’s
employment with the Company terminates for any reason and subsequently a Change in Control shall occur, the Executive shall not be entitled to any benefits hereunder except as otherwise provided pursuant to Section 1.5 and Section 4.1.

 3.2      Termination of Employment. 

(a)      If the Change in Control Date occurs during the Term, any termination of the Executive’s
employment by the Company or by the Executive within twenty-four (24) months following the Change in Control Date (other than due to the death of the Executive) shall be communicated by a written notice to the other party hereto (the
“Notice of Termination”), given in accordance with Section 7. Following the Change in Control Date, any Notice of Termination shall: (i) indicate the specific termination provision (if any) of this Agreement relied upon by
the party giving such notice, (ii) to the extent applicable, set forth in reasonable detail the facts and circumstances claimed to provide a basis for termination of the 

  
 -4- 













 
Executive’s employment under the provision so indicated and (iii) specify the Date of Termination. Following the Change in Control Date, the Date of Termination shall be the close of
business on the date specified in the Notice of Termination (which date may not be less than 15 days or more than 120 days after the date of delivery of such Notice of Termination), in the case of a termination other than one due to the
Executive’s death, or the date of the Executive’s death, as the case may be. In the event the Company fails to satisfy the requirements of Section 3.2(a) regarding a Notice of Termination, following the Change in Control Date, the
purported termination of the Executive’s employment pursuant to such Notice of Termination shall not be effective for purposes of this Agreement. 

(b)    The failure by the Executive or the Company to set forth in the Notice of Termination any fact or circumstance
which contributes to a showing of Good Reason or Cause shall not waive any right of the Executive or the Company, respectively, hereunder or preclude the Executive or the Company, respectively, from asserting any such fact or circumstance in
enforcing the Executive’s or the Company’s rights hereunder; provided, however, that any fact or circumstance which contributes to a showing of Good Reason must be asserted within 90 days of its first occurring and the Company shall have
at least 30 days in which to cure such fact or circumstance consistent with the terms of Section 1.6 above. 

(c)    Following the Change in Control Date, any Notice of Termination for Cause given by the Company must be given
within 90 days of the occurrence of the event(s) or circumstance(s) which constitute(s) Cause. Prior to any Notice of Termination for Cause being given (and prior to any termination for Cause being effective) after the Change in Control Date, the
Executive shall be entitled to a hearing before the Board at which he may, at his election, be represented by counsel and at which he shall have a reasonable opportunity to be heard. Such hearing shall be held on not less than 15 days prior written
notice to the Executive stating the Board’s intention to terminate the Executive for Cause and stating in detail the particular event(s) or circumstance(s) which the Board believes constitutes Cause for termination. 

(d)    Any Notice of Termination for Good Reason given by the Executive, whether prior to or following the Change in
Control Date, must be given consistent with Section 1.6 above. 
 4.        Benefits to
Executive upon Termination. 
 4.1      Termination of Employment without Cause or for Good Reason
prior to Change in Control. If, during the Term and prior to the occurrence of a Change in Control, the Executive’s employment with the Company is terminated by the Company (other than for Cause, Disability or death) or by the Executive for
Good Reason, then: 
 (a)    on the Date of Termination, the Company shall pay to the Executive, in a lump sum in cash,
the sum of (i) the Executive’s base salary earned but unpaid as of the Date of Termination, (ii) the product of (A) the annual bonus paid or payable (including any bonus or portion thereof which has been earned but deferred) to
the Executive for the most recently completed fiscal year and (B) a fraction, the numerator of which is the number of days in the current fiscal year through the Date of Termination, and the denominator of which is 365 and (iii) the amount
of any compensation previously deferred by the Executive (together with 

  
 -5- 













 
any accrued interest or earnings thereon), provided that such payment of deferred compensation is consistent with any elections the Executive may have made with respect thereto and any accrued
vacation pay, in each case to the extent not previously paid (the sum of the amounts described in clauses (i), (ii) and (iii) shall be hereinafter referred to as the “Accrued Obligations”); 

(b)      provided that Executive executes the release consistent with Section 4.7 below, the Company
shall; 
 (i)        pay to the Executive, in nine (9) monthly installments beginning in the
first payroll period following the Release Effective Date (as defined in Section 4.7), the amount equal to (i) 0.75 multiplied by (ii) the sum of (A) the Executive’s highest annual base salary during the three-year period prior
to the Date of Termination and (B) the Executive’s highest annual bonus during the three-year period prior to the Date of Termination; and 

(ii)       for a period of nine (9) months following the Release Effective Date, to the extent
permitted by applicable non-discrimination rules, continue to provide group health insurance coverage to the Executive and the Executive’s family at least equal to those which would have been provided to
them if the Executive employment had not been terminated, in accordance with the applicable plan in effect on the Measurement Date or, if more favorable to the Executive and his family, in effect generally at any time thereafter with respect to
other similarly-situated executives of the Company and its affiliated companies, pursuant to the federal COBRA law; provided, however, that if the Executive becomes reemployed with another employer and is eligible to receive group
health insurance from such employer on terms at least as favorable to the Executive and his family as those being provided by the Company, then the Company shall no longer be required to provide such coverage to the Executive and his family. 

4.2      Termination of Employment without Cause or for Good Reason following Change in Control. If the
Executive’s employment with the Company is terminated by the Company (other than for Cause, Disability or death) or by the Executive for Good Reason during the Term and within twenty-four (24) months following the Change in Control Date,
then: 
 (a)      the Company shall pay to the Executive the Accrued Obligations, which shall be paid in one
lump sum in cash on the Date of Termination; 
 (b)      provided the Executive executes the release
consistent with Section 4.7 below, the Company shall: 
 (i)        pay the amount equal to
the sum of (A) the Executive’s highest annual base salary during the three-year period prior to the Date of Termination and (B) the Executive’s highest annual bonus during the three-year period prior to the Date of Termination,
which shall be paid in one lump sum within 10 days after the Release Effective Date; provided that if the Date of Termination precedes the closing of the Change in Control, then the foregoing amount shall be paid in accordance with the terms of
Section 4.1(b)(i) until the closing date of the Change in Control and thereafter shall be paid out in accordance with this Section 4.1(b)(i); 

  
 -6- 













 (ii)       for twelve (12) months following the
Release Effective Date, to the extent permitted by applicable non-discrimination rules, continue to provide group health insurance coverage to the Executive and the Executive’s family at least equal to
those which would have been provided to them if the Executive’s employment had not been terminated, in accordance with the applicable plan in effect on the Measurement Date or, if more favorable to the Executive and his family, in effect
generally at any time thereafter with respect to other similarly-situated executives of the Company and its affiliated companies, pursuant to the federal COBRA law; provided, however, that if the Executive becomes reemployed with
another employer and is eligible to receive group health insurance from such employer on terms at least as favorable to the Executive and his family as those being provided by the Company, then the Company shall no longer be required to provide such
coverage to The Executive and his family; and 
 (iii)      (A) each outstanding option to purchase shares of
Common Stock of the Company held by the Executive shall become immediately exercisable in full and shares of Common Stock of the Company received upon exercise of any options will no longer be subject to a right of repurchase by the Company,
(B) each outstanding restricted stock award held by the Executive shall be deemed to be fully vested and will no longer be subject to a right of repurchase by the Company and (C) each outstanding award of shares of Common Stock of the
Company, or other award that is valued in whole or in part reference to, or is otherwise based on, shares of Common Stock of the Company or other property, including without limitation, restricted stock units, held by the Executive shall become
immediately exercisable in full, deemed to be fully vested and no longer be subject to a right of repurchase by the Company, as the case may be. 

4.3      Resignation without Good Reason following Change in Control; Termination for Death or
Disability. If the Executive voluntarily terminates his employment with the Company within 24 months following the Change in Control Date, excluding a termination for Good Reason, or if the Executive’s employment with the Company is
terminated by reason of the Executive’s death or Disability, then the Company shall pay the Executive (or his estate, if applicable) the Accrued Obligations in a lump sum in cash on the first regular payroll after the Date of Termination. 

4.4      Termination for Cause; Resignation without Good Reason prior to Change in Control. If the
Company terminates the Executive’s employment with the Company for Cause or if the Executive voluntarily terminates his employment with the Company without Good Reason, then the Company shall pay the Executive, in a lump sum in cash on the Date
of Termination, the sum of (a) the Executive’s base salary earned through the Date of Termination and (b) the amount of any compensation previously deferred by the Executive, provided that such payment of deferred compensation is
consistent with any elections the Executive may have made with respect thereto, in each case to the extent not previously paid. 

4.5      Taxes. 

(a)      Notwithstanding any other provision of this Agreement, except as set forth in Section 4.5(b), in
the event that the Company undergoes a “Change in Ownership or Control” (as defined below), the Company shall not be obligated to provide to the Executive a 

  
 -7- 













 
portion of any “Contingent Compensation Payments” (as defined below) that the Executive would otherwise be entitled to receive to the extent necessary to eliminate any “excess
parachute payments” (as defined in Section 280G(b)(l) of the Internal Revenue Code of 1986, as amended (the “Code”)) for the Executive. For purposes of this Section 4.5, the Contingent Compensation Payments so
eliminated shall be referred to as the “Eliminated Payments” and the aggregate amount (determined in accordance with Treasury Regulation Section 1.280G-1,
Q/A-30 or any successor provision) of the Contingent Compensation Payments so eliminated shall be referred to as the “Eliminated Amount.” 

(b)      Notwithstanding the provisions of Section 4.5(a), no such reduction in Contingent Compensation
Payments shall be made if (i) the Eliminated Amount (computed without regard to this sentence) exceeds (ii) the aggregate present value (determined in accordance with Treasury Regulation
Section 1.280G-1, Q/A-31 and Q/A-32 or any successor provisions) of the amount of any additional taxes that would be
incurred by the Executive if the Eliminated Payments (determined without regard to this sentence) were paid to him (including, state and federal income taxes on the Eliminated Payments, the excise tax imposed by Section 4999 of the Code payable
with respect to all of the Contingent Compensation Payments in excess of the Executive’s “base amount” (as defined in Section 280G(b)(3) of the Code), and any withholding taxes). The override of such reduction in Contingent
Compensation Payments pursuant to this Section 4.5(b) shall be referred to as a “Section 4.5(b) Override.” For purpose of this paragraph, if any federal or state income taxes would be attributable to the
receipt of any Eliminated Payment, the amount of such taxes shall be computed by multiplying the amount of the Eliminated Payment by the maximum combined federal and state income tax rate provided bylaw. 

(c)      For purposes of this Section 4.5, the following terms shall have the following respective
meanings: 
 (i)        “Change in Ownership or Control” shall mean a change in
the ownership or effective control of the Company or in the ownership of a substantial portion of the assets of the Company determined in accordance with Section 280G(b)(2) of the Code. 

(ii)       “Contingent Compensation Payment” shall mean any payment (or benefit) in the
nature of compensation that is made or made available (under this Agreement or otherwise) to a “disqualified individual” (as defined in Section 280G(c) of the Code) and that is contingent (within the meaning of
Section 280G(b)(2)(A)(i) of the Code) on a Change in Ownership or Control of the Company. 

(d)      Any payments or other benefits otherwise due to the Executive following a Change in Ownership or
Control that could reasonably be characterized (as determined by the Company) as Contingent Compensation Payments (the “Potential Payments”) shall not be made until the dates provided for in this Section 4.5(d). Within 30 days
after each date on which the Executive first becomes entitled to receive (whether or not then due) a Contingent Compensation Payment relating to such Change in Ownership or Control, the Company shall determine and notify the Executive (with
reasonable detail regarding the basis for its determinations) (i) which Potential Payments constitute Contingent Compensation Payments, (ii) the Eliminated Amount and (iii) whether the Section 4.5(b) Override is applicable.
Within 30 

  
 -8- 













 
days after delivery of such notice to the Executive, the Executive shall deliver a response to the Company (the “Executive Response”) stating either (A) that he agrees with
the Company’s determination pursuant to the preceding sentence or (B) that he disagrees with such determination, in which case he shall set forth (i) which Potential Payments should be characterized as Contingent Compensation
Payments, (ii) the Eliminated Amount, and (iii) whether the Section 4.5(b) Override is applicable. In the event that the Executive fails to deliver an Executive Response on or before the required date, the Company’s initial
determination shall be final. If the Executive states in the Executive Response that he agrees with the Company’s determination, the Company shall make the Potential Payments to the Executive within threat business days following delivery to
the Company of the Executive Response (except for any Potential Payments which are not due to be made until after such date, which Potential Payments shall be made on the date on which they are due). If the Executive states in the Executive Response
that he disagrees with the Company’s determination, then, for a period of 60 days following delivery of the Executive Response, the Executive and the Company shall use good faith efforts to resolve such dispute. If such dispute is not resolved
within such 60-day period, such dispute shall be settled exclusively by arbitration in Boston, Massachusetts, in accordance with the rules of the American Arbitration Association then in effect. Judgment may
be entered on the arbitrator’s award in any court having jurisdiction. The Company shall, within three business days following delivery to the Company of the Executive Response, make to the Executive those Potential Payments as to which there
is no dispute between the Company and the Executive regarding whether they should be made (except for any such Potential Payments which are not due to be made until after such date, which Potential Payments shall be made on the date on which they
are due). The balance of the Potential Payments shall be made within three business days following the resolution of such dispute. Subject to the limitations contained in Sections 4.5(a) and (b) hereof, the amount of any payments to be made to
the Executive following the resolution of such dispute shall be increased by amount of the accrued interest thereon computed at the prime rate announced from time to time by Bank of America or its successor, compounded monthly from the date that
such payments originally were due. 
 (e)      The Contingent Compensation Payments to be treated as
Eliminated Payments shall be determined by the Company by determining the “Contingent Compensation Payment Ratio” (as defined below) for each Contingent Compensation Payment and then reducing the Contingent Compensation Payments in order
beginning with the Contingent Compensation Payment with the highest Contingent Compensation Payment Ratio. For Contingent Compensation Payments with the same Contingent Compensation Payment Ratio, such Contingent Compensation Payment shall be
reduced based on the time of payment of such Contingent Compensation Payments with amounts having later payment dates being reduced first. For Contingent Compensation Payments with the same Contingent Compensation Payment Ratio and the same time of
payment, such Contingent Compensation Payments shall be reduced on a pro rata basis (but not below zero) prior to reducing Contingent Compensation Payment with a lower Contingent Compensation Payment Ratio. The term “Contingent Compensation
Payment Ratio” shall mean a fraction the numerator of which is the value of the applicable Contingent Compensation Payment that must be taken into account by the Executive for purposes of Section 4999(a) of the Code, and the
denominator of which is the actual amount to be received by the Executive in respect of the applicable Contingent Compensation Payment. For example, in the case of an equity grant that is treated as contingent on the Change in Ownership or Control
because the time at which the payment is made or the payment vests is 

  
 -9- 













 
accelerated, the denominator shall be determined by reference to the fair market value of the equity at the acceleration date, and not in accordance with the methodology for determining the value
of accelerated payments set forth in Treasury Regulation Section 1.280G-lQ/A-24(b) or (c)). 

(f)      The provisions of this Section 4.5 are intended to apply to any and all payments or benefits
available to the Executive under this Agreement or any other agreement or plan of the Company under which the Executive receives Contingent Compensation Payments. 

4.6      Distributions; Section 409A of the Code. 

(a)      Subject to the provisions in this Section 4.6, any severance payments or benefits under this
Agreement shall begin only upon the date of the Executive’s “separation from service” (determined as set forth below) which occurs on or after the Executive’s Date of Termination. It is intended that each installment of the
payments and benefits provided under this Section 4 shall be treated as a separate “payment” for purposes of Section 409A of the Code and the guidance issued thereunder (“Section 409A”).
Neither the Company nor the Executive shall have the right to accelerate or defer the delivery of any such payments or benefits except to the extent specifically permitted or required by Section 409A. 

(b)      If, as of the date of the “separation from service” of the Executive from the Company, the
Executive is not a “specified employee” (each within the meaning of Section 409A), then each installment of the severance payments and benefits shall be made on the dates and terms set forth in this Section 4. 

(c)      If, as of the date of the Executive’s “separation from service” from the Company, the
Executive is a “specified employee” (each, for purposes of this Agreement, within the meaning of Section 409A), then: 

(i)        Each installment of the severance payments and benefits due under this Section 4
that, in accordance with the dates and terms set forth herein, will in all circumstances, regardless of when the separation from service occurs, be paid within the short-term deferral period (as defined under Section 409A) shall be treated as a
short-term deferral within the meaning of Treasury Regulation Section 1.409A-1(b)(4) to the maximum extent permissible under Section 409A and such payments and benefits shall be paid or provided on
the dates and terms set forth in this Agreement; and 
 (ii)       Each installment of the severance
payments and benefits due under this Section 4 that is not described in Section 4.6(c)(i) above and that would, absent this subsection, be paid within the six-month period following the
Executive’s “separation from service” from the Company shall not be paid until the date that is six months and one day after such separation from service (or, if earlier, the death of the Executive), with any such installments that
are required to be delayed being accumulated during the six-month period and paid in a lump sum on the date that is six months and one day following the Executive’s separation from service and any
subsequent installments, if any, being paid in accordance with the dates and terms set forth herein; provided, however, that the preceding provisions of this 

  
 -10- 













 
sentence shall not apply to any installment of severance payments and benefits if and to the maximum extent that such installment is deemed to be paid under a separation pay plan that does not
provide for a deferral of compensation by reason of the application of Treasury Regulation 1.409A-l(b)(9)(iii) (relating to separation pay upon an involuntary separation from service). Any installments that
qualify for the exception under Treasury Regulation Section 1.409A-1(b)(9)(iii) must be paid no later than the last day of the second taxable year of the Executive following the taxable year of the
Executive in which the separation from service occurs. 
 (d)      The determination of whether and when the
Executive’s separation from service from the Company has occurred shall be made and in a manner consistent with and based on the presumptions set forth in, Treasury Regulation Section 1.409A-l(h).
Solely for purposes of this Section 4.6, “Company” shall include all persons with whom the Company would be considered a single employer under Section 414 and 414(c) of the Code. 

(e)      All reimbursements and in-kind benefits provided under this
Agreement shall be made or provided in accordance with the requirements of Sections 409A to the extent that such reimbursements or in-kind benefits are subject to Section 409A, including, where
applicable, the requirements that (i) any reimbursement is for expenses incurred during the Executive’s lifetime (or during a shorter period of time specified in this Agreement), (ii) the amount of expenses eligible for reimbursement
during a calendar year may not affect the expenses eligible for reimbursement in any other calendar year, (iii) the reimbursement of an eligible expense will be made on or before the last day of the calendar year following the year in which the
expense is incurred and (iv) the right to reimbursement is not subject to set off or liquidation or exchange for any other benefit. 

(f)      Notwithstanding anything herein to the contrary, neither the Company, the Board nor its or their
designees or agents shall have any liability to the Executive or to any other person if the payments and benefits provided hereunder that are intended to be exempt from or compliant with Section 409A are not so exempt or compliant. 

4.7      Release; Sole Remedy. The Company’s obligation to make the severance payments and provide
the severance benefits to the Executive under this Agreement are conditioned upon (i) the execution by the Executive of a release of claims (in a form provided by the Company within fourteen (14) days following the end of Executive’s
employment)(the “Release”) within 60 days following the Date of Termination, and (ii) the Executive’s compliance with any employment, consulting, advisory, nondisclosure, non-competition or
other similar agreement between the Executive and the Company, provided that the Executive shall be deemed to have been in compliance with the provisions of such agreement if, within ten (10) days of written notice thereof, such noncompliance
is cured, unless the Board determines in good faith that noncompliance is not curable, and (b) constitute the sole remedy of the Executive in the event of a termination of the Executive’s employment for any reason. The date on which the
Release becomes effective shall be the “Release Effective Date.” Notwithstanding the foregoing, if the 60th day following the date of termination occurs in the calendar year
following the calendar year of the termination, then the Release Effective Date shall be no earlier than January 1 of such subsequent calendar year.

 4.8      Mitigation. The Executive shall not be
required to mitigate the amount of any payment or benefits provided for in this Section 4 by seeking other employment or otherwise. Further, except as provided in Section 4.5, the amount of any payment or benefits provided for in this
Section 4 shall not be reduced by any compensation earned by the Executive as a result of employment by another employer, by retirement benefits, by offset against any amount claimed to be owed by the Executive to the Company or otherwise. 

5.        Disputes. 

5.1      Settlement of Disputes; Arbitration. All claims by the Executive for benefits under this
Agreement shall be directed to and determined by the Board and shall be in writing. Any denial by the Board of a claim for benefits under this Agreement shall be delivered to the Executive in writing and shall set forth the specific reasons for the
denial and the specific provisions of this Agreement relied upon. The Board shall afford a reasonable opportunity to the Executive for a review of the decision denying a claim. Any further dispute or controversy arising under or in connection with
this Agreement shall be settled exclusively by binding arbitration in Boston, Massachusetts, in accordance with the Employment Arbitration rules of the American Arbitration Association then in effect. Judgment may be entered on the arbitrator’s
award in any court having jurisdiction. 
 5.2      Expenses. If the Change in Control Date occurs
during the Term, the Company agrees to pay as incurred, to the full extent permitted by law, all legal, accounting and other fees and expenses which the Executive may reasonably incur after the Change in Control Date as a result of any claim or
contest (regardless of the outcome thereof) by the Company, the Executive or others regarding the validity or enforceability of, or liability under, any provision of this Agreement or any guarantee of performance thereof (including as a result of
any contest by the Executive regarding the amount of any payment or benefits pursuant to this Agreement), plus in each case interest on any delayed payment at the applicable Federal rate provided for in Section 7872(f)(2)(A) of the Code. 

5.3      Compensation During a Dispute. If the Change in Control Date occurs during the Term and the
Executive’s employment with the Company terminates within twenty-four (24) months following the Change in Control Date, and the right of the Executive to receive benefits under Section 4 (or the amount or nature of the benefits to
which he is entitled to receive) axe the subject of a bona fide dispute between the Company and the Executive, the Company shall continue (a) to pay to the Executive his base salary in effect as of the Measurement Date and (b) to provide
benefits to the Executive and the Executive’s family at least equal to those which would have been provided to them, if the Executive’s employment had not been terminated, in accordance with the applicable benefit plans in effect on the
Measurement Date, until such dispute is resolved either by mutual written agreement of the parties or by an arbitrator’s award pursuant to Section 5.1. Following the resolution of such dispute, the sum of the payments made to the Executive
under clause (a) of this Section 5.3 shall be deducted from any cash payment which the Executive is entitled to receive pursuant to Section 4; and if such sum exceeds the amount of the cash payment which the Executive is entitled to
receive pursuant to Section 4, the excess of such sum over the amount of such payment shall be repaid (without interest) by the Executive to the Company within 60 days of the resolution of such dispute.

 6.        Successors. 

6.1      Successor to Company. The Company shall require any successor (whether direct or indirect, by
purchase, merger, consolidation or otherwise) to all or substantially all of the business or assets of the Company expressly to assume and agree to perform this Agreement to the same extent that the Company would be required to perform it if no such
succession had taken place. Failure of the Company to obtain an assumption of this Agreement at or prior to the effectiveness of any succession shall be a breach of this Agreement and shall constitute Good Reason if the Executive elects to terminate
employment, except that for purposes of implementing the foregoing, the date on which any such succession becomes effective shall be deemed the Date of Termination. As used in this Agreement, “Company” shall mean the Company as defined
above and any successor to its business or assets as aforesaid which assumes and agrees to perform this Agreement, by operation of law or otherwise. 

6.2    Successor to Executive. This Agreement shall inure to the benefit of and be enforceable by the
Executive’s personal or legal representatives, executors, administrators, successors, heirs, distributees, devisees and legatees. If the Executive should die while any amount would still be payable to the Executive or his family hereunder if
the Executive had continued to five, all such amounts, unless otherwise provided herein, shall be paid in accordance with the terms of this Agreement to the executors, personal representatives or administrators of the Executive’s estate. 

7.        Notice. All notices, instructions and other communications given hereunder or in
connection herewith shall be in writing. Any such notice, instruction or communication shall be sent either (i) by registered or certified mail, return receipt requested, postage prepaid, or (ii) prepaid via a reputable nationwide
overnight courier service, in each case addressed to the Company, at 200 Minuteman Road, Andover, Massachusetts 01810, Attn: Chief Executive Officer, and to the Executive at the Executive’s last residential address on file at the Company (or to
such other address as either the Company or the Executive may have furnished to the other in writing in accordance herewith). Any such notice, instruction or communication shall be deemed to have been delivered five business days after it is sent by
registered or certified mail, return receipt requested, postage prepaid, or one business day after it is sent via a reputable nationwide overnight courier service. Either party may give any notice, instruction or other communication hereunder using
any other means, but no such notice, instruction or other communication shall be deemed to have been duly delivered unless and until it actually is received by the party for whom it is intended. 

8.        Miscellaneous. 

8.1    Employment by Subsidiary. For purposes of this Agreement, the Executive’s employment with the Company
shall not be deemed to have terminated solely as a result of the Executive continuing to be employed by a wholly-owned subsidiary of the Company. 

8.2    Severability. The invalidity or unenforceability of any provision of this Agreement shall not affect the
validity or enforceability of any other provision of this Agreement, which shall remain in full force and effect.

 8.3      Injunctive Relief. The Company and the
Executive agree that any breach of this Agreement by the Company is likely to cause the Executive substantial and irrevocable damage and therefore, in the event of any such breach, in addition to such other remedies which may be available, the
Executive shall have the right to specific performance and injunctive relief. 
 8.4      Governing
Law. The validity, interpretation, construction and performance of this Agreement shall be governed by the internal laws of the Commonwealth of Massachusetts, without regard to conflicts of law principles. 

8.5      Waivers. No waiver by the Executive at any time of any breach of, or compliance with, any
provision of this Agreement to be performed by the Company shall be deemed a waiver of that or any other provision at any subsequent time.

be an original but both of which together shall constitute one and the same instrument. 
 8.7      Tax
Withholding. Any payments provided for hereunder shall be paid net of any applicable tax withholding required under federal, state or local law. 

8.8      Entire Agreement. This Agreement sets forth the entire agreement of the parties hereto in
respect of the subject matter contained herein and supersedes all prior agreements, promises, covenants, arrangements, communications, representations or warranties, whether oral or written, by any officer, employee or representative of any party
hereto in respect of the subject matter contained herein; and any prior agreement of the parties hereto in respect of the subject matter contained herein is hereby terminated and cancelled. 

8.9      Amendments. This Agreement may be amended or modified only by a written instrument executed by
both the Company and the Executive.
