that during the Term of this Agreement and for two (2) years after the Executive’s Date of Termination resulting from the Executive’s resignation, retirement or a termination by the Company for Cause, the Executive will not directly
or indirectly engage in any of the Restricted Activities. 
 4. Termination Benefits and Covenants: 

4.1 For the Executive: In consideration of, and as condition to, the performance by the Executive of the
covenants, undertakings and other agreements set forth in Section 4.3 below, and for so long as the Executive performs such obligations, the Company shall provide the Termination Benefits described in subsections (a)-(f) below to the Executive
if his employment with the Company is terminated by the Company for any reason other than for death, Disability, or Cause, provided that such termination by the Company does not trigger or entitle the Executive to any payments or benefits under the
Amended and Restated Executive Officer Amended and Restated Change in Control Agreement dated contemporaneously herewith (the “Change in Control Agreement”). If the Executive’s employment with the Company is terminated within
twenty-four (24) months following a Change in Control or within three (3) months prior to an actual Change in Control, then the terms and conditions of the Change in Control Agreement shall govern such employment termination and the
Executive shall not be entitled to the payments and benefits described below. Subject to Section 4.1(b)(i) of this Agreement but notwithstanding any other provision of this Agreement to the contrary, payment or provision of the Executive’s
Termination Benefits that are subject to Section 409A of the Code shall commence on the 60th day following the Date of Termination provided the Executive has complied with the requirements of Section 4.3 of this Agreement and the release of claims has become irrevocable under applicable law
no later than on the 60th day following his Date of
Termination. All Termination Benefits shall be forfeited as of the 60th day following the Executive’s Date of Termination if the Executive has not provided the Company with a valid, irrevocable release of claims as of such 60th day. 

(a) Continued Payments: Unless otherwise required under Section 4.1(b) below, the Company
shall pay monthly to the Executive an amount equal to
1/12th of his current annual Model Compensation as of the
Date of Termination 

  
 4 








 
for a period of twenty-four (24) months from the Date of Termination (the “Severance Period”). Except as otherwise expressly provided herein, under no circumstances shall the
Executive receive more than a total of twenty-four (24) months of payments under this Agreement. All such continued payments shall be in accord with the Company’s customary pay practices. 

(b) Deferred Compensation/Section 409A. 

(i) Notwithstanding any other provision of this Agreement, if the Executive is a “specified employee” at
the time of Executive’s “separation from service,” as defined in Section 409A of the Code, all payments, benefits, or removal of restrictions on the transfer of equity under this Agreement with respect to Executive’s
separation from service that constitute compensation deferred under a nonqualified deferred compensation plan as defined in Section 409A of the Code to which such specified employee would otherwise be entitled during the first six months
following the date of separation from service shall be made on the first day of the seventh month after the date of separation from service (or, if earlier, the date of death of the Executive). 

(ii) For purposes of this Agreement, each amount to be paid or benefit to be provided shall be construed as a separate
identified payment for purposes of Section 409A, and any payments that are due within the “short term deferral period” as defined in Section 409A or payments that are made under separation pay plans as described in Treasury
Regulation Section 1.409A-1(b)(ii), (iii) or (iv), shall not be treated as deferred compensation unless applicable law requires otherwise. Neither the Company nor the Executive shall have the right to accelerate or defer the delivery of
any payments or benefits under this Agreement except to the extent specifically permitted or required by Section 409A. 
 (iii) This Agreement is intended to comply with the provisions of Section 409A and the Agreement shall, to the extent practicable, be construed in accordance therewith. Terms defined in the Agreement
shall have the meanings given such terms under Section 409A if and to the extent required to comply with Section 409A. In any event, the Company makes no representations or warranty and shall have no liability to Executive or any other
person if any provisions of or payments under this Agreement are determined to constitute deferred compensation subject to Code Section 409A but not to satisfy the conditions of that section. 

(c) Benefits: During the Severance Period, the Company shall arrange or provide for continued health, dental and
vision insurance plan coverage for the Executive at the same levels of coverage in existence prior to the Date of Termination subject to the Company and Executive each contributing to the applicable insurance premium payments on the same basis and
in the same proportions as in existence at the Date of Termination. If the Executive is not eligible for continued health, dental and vision insurance plan coverage for any 

  
 5 








 
portion of the Severance Period, the Company shall provide or reimburse the Executive for comparable individual insurance and, if such provision or reimbursement constitutes taxable income to the
Executive, such additional amount as is necessary to place the Executive in substantially the same after tax position as he was while an employee of the Company with respect to such insurance plan coverages. All other benefits, including but not
limited to flex/vacation time accrual, short and long term disability insurance, life insurance, contributions (including company matches) into savings plan and savings plan plus, profit sharing payments and participation in the employee stock
purchase plan shall cease as of the Date of Termination. 
 To the extent that amounts paid by the Company to
provide benefits under this paragraph (c), are deemed to be deferred compensation subject to Section 409A, then such payments shall be made monthly and to the extent any such benefits are reimbursements of expenses incurred by the Executive
then the expenses eligible for reimbursement in one taxable year may not effect the expenses eligible for reimbursement in another taxable year; such reimbursement must be made on or before the last day of the year following the year in which the
expenses are incurred; and the right to reimbursement is not subject to liquidation or exchange for another benefit. 
 (d) Equity Awards: All unvested Equity Awards held by the Executive as of the date of the Executive’s termination by the Company shall continue to vest during the Severance Period as if the
Executive’s employment had not been terminated. Except as modified in this Section 1(d), the terms of the applicable equity Plan(s) and Equity Award Agreements (including any successor plans and agreements) under which the Equity Awards
were granted to the Executive shall continue to govern all of the Executive’s Equity Awards. 
 (e) Taxes
and Withholdings: All payments made by the Company to the Executive under this Agreement shall be net of any applicable taxes (whether local, state, federal, provincial or otherwise) or other required or voluntary withholdings or deductions.

 (f) Notwithstanding anything to the contrary herein, in the event the Executive dies after (i) his
employment with the Company has been terminated for any reason other than Death, Disability and Cause and (ii) his right to the Termination Benefits stated in Section 4.1 has attached, the Company agrees that the Executive’s estate,
conservator or designated beneficiary(ies), as the case may be, shall be entitled to the remainder of the Executive’s Termination Benefits described in Section 4.1. 

  
 6 








 4.2 Notwithstanding the preceding Section 4.1 and in consideration of, and as condition
to, the Executive providing to the Company the covenants and agreements set forth in Section 4.3 below, the Company agrees that if the Executive’s employment with the Company is terminated by the Company for Disability, the Company shall,
unless otherwise required under Section 4.1(b) above: 
 (a) provide the monthly payments described in
Section 4.1(a) above, as reduced pursuant to 4.2(b) below, to the Executive for each month during the two (2) year period following his termination during which the Executive does not receive or is no longer eligible to receive any Company
disability insurance benefits under the applicable insurance policy or program(s), other than as a result of Executive’s intentional malfeasance or death; and 

(b) under this Section 4.2, reduce each monthly payment described in Section 4.1(a) above to the Executive by
any compensation received by the Executive from other employment, consulting or the rendition of services outside the Restricted Activities. 

The Executive agrees to use his best efforts to obtain and maintain any benefits from any disability policy or program under which he is an insured party
or participant. 
 4.3 Executive’s Covenants: In consideration of, and as a condition to, the Company providing to
the Executive the Termination Benefits set forth in Sections 4.1 and 4.2, the Executive covenants and agrees: 

(a) that during the Term of this Agreement and for two (2) years after the Executive’s Date of Termination
resulting from a termination by the Company for any reason other than for Death or Disability and so long as such termination does not trigger or entitle the Executive to any payments or benefits under the Change in Control Agreement, the Executive
will not directly or indirectly engage in any of the Restricted Activities. 
 (b) to sign a valid, binding,
irrevocable general release of any claims he has or may have against the Company, including its subsidiaries, in connection with or relating to his employment by and/or termination from employment with the Company in the form attached hereto as
Attachment A, within twenty-one (21) days of his Date of Termination resulting from a termination by the Company. Notwithstanding the foregoing, the Company agrees and hereby acknowledges that the Release contained in Attachment A
is not intended to and does not (i) apply to any claims the Executive may bring to enforce the terms of this Agreement, the Change in Control Agreement, or any outstanding Equity Award Agreement and applicable equity Plan; (ii) release the
Company of any obligation it may have pursuant to a written agreement, the Company’s articles or organization or bylaws or as mandated by statute to indemnify the Executive as an officer or director of the Company; and (iii) release the
Company of any obligation to provide and/or pay benefits to the Executive or the Executive’s estate, conservator or designated beneficiary (ies) under and in accordance with the terms of any applicable Company benefit plan and/or program.

relating in any way to Executive’s positions, duties and responsibilities while at the Company or to any matters which the Executive handled, participated in or had knowledge of while employed by the Company., 

(e) not to make any false or disparaging or derogatory statements or remarks to any person or entity about the
Company’s (including its subsidiaries’) business affairs, financial condition, or about any Company or subsidiary directors, officers, employees, stockholders and agents. 

4.4 Return of Property: Within sixty (60) days of the Executive’s termination of employment, for any reason, or his

for business expenses incurred prior to the Date of Termination. 
 4.5 No Termination Benefits: Except as expressly

Control Agreement. 
 5. Termination Notice: Any termination of the Executive’s employment by the Company (other
than by reason of Death) shall (a) be in writing; (b) indicate the basis for termination (such as with or without Cause, Disability, etc...) and with respect to a termination for Cause indicate the basis for termination in reasonable
detail and (c) be delivered to the Executive in accordance with Section 17 below.

 9. No Obligation of Employment. Nothing in this Agreement shall be construed as an express or implied contract of employment between the Executive and the Company (or its subsidiaries, affiliate or
divisions) or as a commitment on the part of the Company to retain Executive in any capacity for any period of time. Executive understands that the employment relationship between the Executive and the Company will be “at will” and the
Executive understands that the Company may terminate Executive with or without “Cause” at any time (including prior to a Change in Control) or for any or no reason. Following any Change in Control, the Company may also terminate Executive

irreparably harmed, and (d) the award of monetary damages will not adequately protect the Company, its subsidiaries and affiliates in the event of a breach hereof by the Executive. As a result, the Executive agrees and consents that if he
violates any of the provisions of this Agreement, the Company shall, without any bond or other security, being required and without the necessity of proving monetary damages, be entitled to temporary and/or permanent injunctive relief to be issued
by a court of competent jurisdiction restraining the Executive from committing or continuing any violation of this Agreement or any other appropriate decree of specific performance. Such remedies shall not be exclusive and shall be in addition to
any other remedy the Company may have whether at law or in equity. 
 11. Dispute Resolution: Except for the equitable
relief provisions set forth in Section 10, the Executive and the Company agree that any dispute, controversy or claim arising between the parties relating to this Agreement, otherwise relating in any way to Executive’s employment with
and/or termination from the Company, or relating to 

  
 9 








 
Executive’s relationship as a director or in any other capacity for the Company (whether such dispute arises under any federal, state or local statute or regulation, or at common law), shall
be resolved by final and binding arbitration before a single arbitrator. The arbitrator shall be selected in accordance with the Employment Dispute Resolution Rules of the American Arbitration Association (“AAA”) pertaining at the time the
dispute arises. The parties agree that such arbitration shall take place at the offices of the AAA in Boston, Massachusetts. In such arbitration proceedings, the arbitrator shall have the discretion, to be exercised in accordance with applicable
law, to allocate among the parties the arbitrator’s fees, tribunal and other administrative and litigation costs and, to the prevailing party, reasonable attorneys’ fees. The award of the arbitrator may be confirmed before and entered as a
judgment of any court having jurisdiction of the parties. 
 12. Governing Law. This Agreement shall be governed by and
construed in accordance with the internal laws of the Commonwealth of Massachusetts and this Agreement shall be deemed to be performable in Massachusetts. 
 13. Severability. In case any one or more of the provisions contained in this Agreement for any reason shall be held to be invalid, illegal or unenforceable in any respect, such invalidity,
illegality or unenforceability shall not affect any other provision of this Agreement and this Agreement shall be construed to the maximum extent permitted by law. 
 14. Waivers and Modifications. This Agreement may be modified, and the rights, remedies and obligations contained in any provision hereof may be waived, only in accordance with this
Section 14. No waiver by either party of any breach by the other or any provision hereof shall be deemed to be a waiver of any later or other breach thereof or as a waiver of any other provision of this Agreement. This Agreement may not be
waived, changed, discharged or terminated orally or by any course of dealing between the parties, but only by an instrument in writing signed by the party against whom any waiver, change, discharge or termination is sought. 

15. Assignment. Executive may not assign any of his rights or delegate any of his duties or obligations under this Agreement. The
rights and obligations of the Company under this Agreement shall inure to the benefit of, and shall be binding upon, the successors and assigns of the Company. 
 16. Entire Agreement. This Agreement constitutes the entire understanding of the parties relating to the subject matter hereof and supersedes and cancels all agreements, written or oral, made prior
to the date hereof between Executive and the Company relating to the subject matter hereof including the Agreement Regarding Termination Benefits entered into between Teradyne, Inc. and the Executive dated September 3, 2004 ; provided, however,
