 Exhibit 10.9 

TERADYNE, INC. 
 2006
EQUITY AND CASH COMPENSATION INCENTIVE PLAN 
 (as amended through November 15, 2016) 

1. Purpose and Eligibility. 
 The purpose
of this 2006 Equity and Cash Compensation Incentive Plan (the “Plan”) of Teradyne, Inc. is to provide equity ownership and compensation opportunities in the Company (each an “Award”) to employees, officers,
directors, consultants and advisors of the Company and its Subsidiaries, all of whom are eligible to receive Awards under the Plan. Any person to whom an Award has been granted under the Plan is called a “Participant.” Additional
definitions are contained in Section 14(a). 
 2. Administration. 

a. Administration by Committee of Independent Members of the Board of Directors. The Plan will be administered by a
committee (the “Committee”) composed solely of members of the Board of Directors of the Company that are “independent,” as defined pursuant to Rule 10A-3(b)(1) of the Securities
Exchange Act of 1934, as amended, and as proscribed under Rule 303A.02 of the New York Stock Exchange (“NYSE”) Listed Company Manual, or any amendment, supplement or modification thereto; provided, however, that, except with
respect to Awards granted to non-employee directors which shall be granted and administered by the Committee, at any time and on any one or more occasions the Board may itself exercise any of the powers and
responsibilities assigned the Committee under the Plan and when so acting shall have the benefit of all of the provisions of the Plan pertaining to the Committee’s exercise of its authorities hereunder. The Committee, in its sole discretion,
shall have the authority to grant Awards, to adopt, amend and repeal rules relating to the Plan, to interpret and correct the provisions of the Plan and any Award, and, subject to the limitations of the Plan, to modify and amend any Award. All
decisions by the Committee shall be final and binding on all interested persons. Neither the Company nor any member of the Committee shall be liable for any action or determination relating to the Plan. 

b. Delegation to Executive Officers. To the extent permitted by applicable law, the Committee may delegate to one or more
executive officers of the Company the power to grant Awards and exercise such other powers under the Plan as the Committee may determine; provided, however, that the Committee shall fix the maximum number of Awards to be granted and the
maximum number of shares issuable to any one Participant pursuant to Awards granted by such executive officer or officers. The Committee may, by a resolution adopted by the Committee, authorize one or more executive officers of the Company to do one
or both of the following: (i) designate employees of the Company or of any of its subsidiaries to be recipients of Awards and (ii) determine the number, type and terms of such Awards to be received by such employees, subject to the
limitations of the Plan; provided, however, that, in each case, the resolution so authorizing such officer or officers shall specify the maximum number and type of Awards such officer or officers may so award. The Committee may not authorize
an officer to designate himself or herself as a recipient of any such Awards or to grant Awards to other executive officers of the Company. 
 3. Stock
Available for Awards. 
 a. Number of Shares. Subject to adjustment under Section 3(c), the aggregate number of
shares (the “Authorized Shares”) of the Company’s common stock, $0.125 par value per share (the “Common Stock”), that may be issued pursuant to the Plan shall be 32,000,000 shares of Common Stock. If any Award
expires, is terminated, surrendered, forfeited, expires unexercised, is settled in cash in lieu of Common Stock or is exchanged for other Awards, in whole or in part, the unissued Common Stock covered by such Award shall again be available for the
grant of Awards under the Plan. Shares of Common Stock delivered to the Company by a Participant to (i) purchase shares upon the exercise of an Award, or (ii) satisfy statutory tax withholding obligations with respect to any Award shall
not be added back to the number of shares available for the future grant of Awards under the Plan. All shares of Common Stock covered by an SAR shall be counted against the number of shares available for the grant of Awards under the Plan; provided,
however, that SARs that may be settled only in cash shall not be so counted. Shares of Common Stock repurchased by the Company on the open market using the proceeds from the exercise of an Award shall not increase the number of shares available for
future grants of Awards. Shares issued under the Plan may consist in whole or in part of authorized but unissued shares. Notwithstanding anything to the contrary in this Plan, the foregoing limitations shall be subject to adjustment under Section
3(c), but only to the extent that such adjustment will not affect the status of any Award intended to qualify as “performance-based compensation” under Section 162(m) of the Code. 

  
 1 

 b. Per-Participant Limit. Subject to
adjustment under Section 3(c), no Participant may be granted stock-based Awards during any one fiscal year to purchase more than 2,000,000 shares of Common Stock. 

c. Adjustment to Common Stock. In the event of any stock split, stock dividend, extraordinary cash dividend,
recapitalization, reorganization, merger, consolidation, combination, exchange of shares, liquidation, spin-off, split-up, or other similar change in capitalization or
event, (i) the number and class of securities available for Awards under the Plan and the per-Participant share limit, (ii) the number and class of securities, vesting schedule and exercise price per
share subject to each outstanding stock-based Award, (iii) the repurchase price per security subject to repurchase, and (iv) the terms of each other outstanding stock-based Award shall be adjusted by the Company (or substituted Awards may
be made) to the extent the Committee shall determine, in good faith, that such an adjustment (or substitution) is appropriate. If Section 11(f)(i) applies for any event, this Section 3(c) shall not be applicable. 

d. Fractional Shares. No fractional shares shall be issued under the Plan and the Participant shall, at the
Committee’s discretion, receive either cash in lieu of such fractional shares or a full share for each fractional share. 
 4. Stock Options.

 a. General. The Committee may grant options to purchase Common Stock (each, an “Option”) and
determine the terms and conditions of each Option, including, but not limited to (i) the number of shares subject to such Option or a formula for determining such, (ii) subject to Section 4(e) hereof, the exercise price of the Options and
the means of payment for the shares, (iii) the Performance Criteria (as defined in Section 11(d)), if any, and level of achievement of such Performance Criteria that shall determine the number of shares or Options granted, issued, retainable
and/or vested, (iv) the terms and conditions of the grant, issuance and/or forfeiture of the shares or Options, and (v) such further terms and conditions as may be determined from time to time by the Committee, in each case not
inconsistent with this Plan. 
 b. Incentive Stock Options. An Option that the Committee intends to be an
“incentive stock option” as defined in Section 422 of the Code (an “Incentive Stock Option”) shall be granted only to employees of the Company and shall be subject to and shall be construed consistently with the
requirements of Section 422 of the Code. The Committee and the Company shall have no liability if an Option or any part thereof that is intended to be an Incentive Stock Option does not qualify as such. 

c. Nonstatutory Stock Options. An Option or any part thereof that does not qualify as an Incentive Stock Option is
referred to herein as a “Nonstatutory Stock Option.” 
 d. Dollar Limitation. For so long as the Code
shall so provide, Options granted to any employee under the Plan (and any other plans of the Company) which are intended to constitute Incentive Stock Options shall not constitute Incentive Stock Options to the extent that such Options, in the
aggregate, become exercisable for the first time in any one calendar year for shares of Common Stock with an aggregate Fair Market Value (as defined in Section 14 and determined as of the respective date or dates of grant) of more than $100,000
(or such other limit as may be provided by the Code). To the extent that any such Incentive Stock Options exceed the $100,000 limitation (or such other limit as may be provided by the Code), such Options shall be Nonstatutory Stock Options. 

e. Exercise Price. The Committee shall establish the exercise price (or determine the method by which the exercise price
shall be established) at the time each Option is granted and specify the exercise price in the applicable Option agreement, provided, that the exercise price per share specified in the agreement relating to each Option granted under the Plan
shall not be less than the Fair Market Value per share of Common Stock on the date of such grant. In the case of an Incentive Stock Option to be granted to an employee owning stock possessing more than ten percent (10%) of the total combined voting
power of all classes of stock of the Company, the price per share specified in the agreement relating to such Incentive Stock Option shall not be less than one hundred ten percent (110%) of the Fair Market Value per share of Common Stock on the date
of grant (or such other limit as may be provided by the Code). For purposes of determining stock ownership under this subsection, the rules of Section 424(d) of the Code shall apply. Subject to Section 3(c), an Option may not be amended subsequent
to its issuance to reduce the price at which it is exercisable unless such amendment is approved by the Company’s shareholders. 

f. Duration of Options. Each Option shall be exercisable at such times and subject to such terms, conditions and
expiration as the Committee may specify in the applicable Option agreement; provided, that no Option shall be exercisable for a period of time greater than ten (10) years from the date of grant of such Option; provided, further,
that Incentive Stock Options granted to an employee owning stock possessing more than ten percent (10%) of the total combined voting power of all classes of stock of the Company shall be exercisable for a maximum of five (5) years from the date
of grant of such Option (or such other limit as may be provided by the Code). For purposes of determining stock ownership under this subsection, the rules of Section 424(d) of the Code shall apply. 

  
 2 

 g. Vesting of Options. At the time of the grant of an Option, the Committee
shall establish a vesting date or vesting dates with respect to the shares of Common Stock covered by such Options; provided that all Options, subject to and except as provided in Sections 11(f), 11(j), 11(l) and 13, shall have a minimum
vesting period of no less than one (1) year. The Committee may establish vesting dates based upon the passage of time and/or the satisfaction of Performance Criteria or other conditions as deemed appropriate by the Committee. 

h. Exercise of Option. Options may be exercised only by delivery to the Company at its principal office address or to
such transfer agent as the Company shall designate of a written notice of exercise specifying the number of shares as to which such Option is being exercised, signed by the proper person, or by notification of the Company-designated third party
commercial provider (the “Third Party Commercial Provider”), in accordance with the procedures approved by the Company and to which the holder of the Option shall have ongoing access by means of accessing such person’s account
maintained with the Third Party Commercial Provider, together with payment in full as specified in Section 4(i) for the number of shares for which the Option is exercised. 

i. Payment Upon Exercise. Common Stock purchased upon the exercise of an Option shall be paid for by one or any
combination of the following forms of payment: 
 (i) in United States dollars in cash or by check payable to order of the
Company or by fund transfer from the Option holder’s account maintained with the Third Party Commercial Provider; 

(ii) at the discretion of the Committee, through delivery of shares of Common Stock having a Fair Market Value equal as of the
date of the exercise to the cash exercise price of the Option, provided, that such shares were not acquired by the Participant in the prior six months; 

(iii) at the discretion of the Committee and consistent with applicable law, through the delivery of an assignment to the
Company of a sufficient amount of the proceeds from the sale of the Common Stock acquired upon exercise of the Option and an authorization to the Third Party Commercial Provider to pay that amount to the Company, which sale shall be at the
Participant’s direction at the time of exercise; or 
 (iv) at the discretion of the Committee, by any combination of
(i), (ii), or (iii) above. 
 If the Committee exercises its discretion to permit payment of the exercise price of an Incentive Stock
Option by means of the methods set forth in clauses (ii), (iii) or (iv) of the preceding sentence, such discretion shall be exercised in writing in the instrument evidencing the Award of the Incentive Stock Option. 

j. Notice to Company of Disqualifying Disposition. By accepting an Incentive Stock Option granted under the Plan, each optionee
agrees to notify the Company in writing immediately after such optionee makes a disqualifying disposition of any stock acquired pursuant to the exercise of the Incentive Stock Options. A “disqualifying disposition” is generally any
disposition occurring on or before the later of (a) the date two years following the date the Incentive Stock Option was granted or (b) the date one year following the date the Incentive Stock Option was exercised. 

k. Issuances of Securities. Except as provided in Section 3(c) or as otherwise expressly provided herein, no issuance by the
Company of shares of stock of any class, or securities convertible into shares of stock of any class, shall affect, and no adjustment by reason thereof shall be made with respect to, the number or price of shares subject to Options. No adjustments
shall be made for dividends paid in cash or in property other than securities of the Company. A Participant that is the holder of an Option shall not be entitled to receive dividends or dividend equivalents declared and payable prior to exercise of
the Option. 
 5. Stock Appreciation Rights 

a. General. A Stock Appreciation Right (a “SAR”) is an Award entitling the holder, upon exercise, to
receive an amount in cash or Common Stock, or a combination thereof (such form to be determined by the Committee), determined solely by reference to appreciation, from and after the date of grant, in the Fair Market Value of a share of Common Stock.
The date as of which such appreciation or other measure is determined shall be the exercise date of the SAR Award. 
 b.
Grants. SARs may be granted in tandem with, or independently of, Options granted under the Plan. 
 (1)
Tandem Awards. When SARs are expressly granted in tandem with Options: (i) the SARs will be exercisable only at such time or times, and to the extent, that the related Option is exercisable, and will be exercisable in
accordance with the procedure required for exercise of the related Option; (ii) the SARs will terminate and no longer be 

  
 3 

 
exercisable upon the termination or exercise of the related Option, except that a SAR granted with respect to less than the full number of shares covered by an Option will not be terminated until
and only to the extent that the number of shares as to which the related Option has been exercised or has terminated exceeds the number of shares not covered by the SAR; (iii) the Option will terminate and no longer be exercisable upon the
exercise of the related SAR; and (iv) the SAR will be transferable only with the related Option. 
 (2)
Independent Stock Appreciation Rights. A SAR not expressly granted in tandem with an Option will become exercisable at such time or times, and on such conditions, as the Committee may specify in the SAR Award. 

c. Terms and Conditions. The Committee shall determine all terms and conditions of a SAR Award, including, but not limited to
(i) the number of shares subject to such SAR Award or a formula for determining such, (ii) the Performance Criteria, if any, and level of achievement of such Performance Criteria that shall determine the number of shares granted, issued,
retainable and/or vested or the amount of cash payable, (iii) the terms and conditions on the grant, issuance and/or forfeiture of the shares, and (iv) such further terms and conditions as may be determined from time to time by the
Committee, in each case not inconsistent with this Plan. Subject to Section 3(c), a SAR may not be amended subsequent to its issuance to reduce the price used to determine the measurement price upon exercise unless such amendment is approved by the
Company’s shareholders. A Participant that is the holder of a SAR Award shall not be entitled to receive dividends or dividend equivalents. The Amendment of all SAR Awards shall be subject to Section 11(n). 

d. Vesting of SAR Awards. At the time of the grant of a SAR Award, the Committee shall establish a vesting date or vesting dates
with respect to such SAR Award, provided that all SAR Awards, subject to and except as provided in Sections 11(f), 11(j), 11(l) and 13, shall have a minimum vesting period of no less than one (1) year; and, provided, further, that SARs
awarded in tandem with Options shall be subject to the same vesting date or vesting dates established by the Committee pursuant to Section 4(g) for such related Options and shall be exercisable only to the extent that such related Option shall then
be exercisable. The Committee may establish vesting dates based upon the passage of time and/or the satisfaction of Performance Criteria or other conditions as deemed appropriate by the Committee. 

6. Restricted Stock. 
 a.
Grants. The Committee may grant Awards entitling recipients to acquire shares of Common Stock, subject to (i) delivery to the Company by the Participant of cash, a check or other sufficient legal consideration in an amount at
least equal to the par value of the shares purchased, (ii) the right of the Company to repurchase or reacquire all or part of such shares at their issue price or other stated or formula price from the Participant in the event that conditions
specified by the Committee in the applicable Award are not satisfied prior to the end of the applicable restriction period or periods established by the Committee for such Award (each, a “Restricted Stock Award”), and
(iii) Section 6(b). 
 b. Terms and Conditions. A Participant that is the holder of a Restricted Stock Award,
whether vested or unvested, shall be entitled to enjoy all shareholder rights with respect to the shares of Common Stock underlying such Restricted Stock Award, including the right to vote such shares. Subject to Section 6(c), the Committee shall
determine all terms and conditions of any such Restricted Stock Award, including, but not limited to (i) the number of shares subject to such Restricted Stock Award or a formula for determining such, (ii) the purchase price of the shares,
if any, and the means of payment for the shares, (iii) the Performance Criteria, if any, and level of achievement of such Performance Criteria that shall determine the number of shares granted, issued, retainable and/or vested, (iv) the
terms and conditions on the grant, issuance and/or forfeiture of the shares, and (v) such further terms and conditions as may be determined from time to time by the Committee, in each case not inconsistent with this Plan. At the
Committee’s election, shares of Common Stock issued in respect of a Restricted Stock Award may be (i) held in book entry form subject to the Company’s instructions until any restrictions relating to the Restricted Stock Award lapses,
or (ii) evidenced by a stock certificate that may bear a legend indicating that the ownership of the shares of Common Stock represented by such certificate is subject to the restrictions, terms and conditions of this Plan and the Restricted
Stock Award. Any stock certificates issued in respect of a Restricted Stock Award shall be registered in the name of the Participant. All certificates registered in the name of the Participant shall, unless otherwise determined by the Committee, be
deposited by the Participant, together with a stock power endorsed in blank, with the Company (or its designee). After the expiration of the applicable restriction periods, the Company (or such designee) shall deliver the certificates no longer
subject to such restrictions to the Participant or, if the Participant has died, to the beneficiary designated by the Participant, in a manner determined by the Committee, to receive amounts due or exercise rights of the Participant in the event of
the Participant’s death (the “Designated Beneficiary”). In the absence of an effective designation by a Participant, Designated Beneficiary shall mean the Participant’s estate. 

c. Vesting of Restricted Stock. At the time of the grant of a Restricted Stock Award, the Committee shall establish a
vesting date or vesting dates with respect to the shares of Common Stock covered by such Restricted Stock Award, which vesting 

  
 4 

 
dates may be based upon the passage of time and/or the satisfaction of Performance Criteria or other conditions as deemed appropriate by the Committee; provided, that all Restricted Stock
Awards, subject to and except as provided in Sections 11(f), 11(j), 11(l) and 13, shall have a minimum vesting period of no less than one (1) year. 

7. Restricted Stock Unit. 
 a.
Grants. The Committee may grant Awards entitling recipients to acquire shares of Common Stock in the future, with the future delivery of the Common Stock subject to a risk of forfeiture or other restrictions that will lapse upon
the satisfaction of one or more specified conditions (each, a “Restricted Stock Unit”). 
 b. Terms and
Conditions. Subject to Section 7(c), the Committee shall determine all terms and conditions of any such Restricted Stock Unit, including, but not limited to (i) the number of shares subject to such Restricted Stock Unit or a formula
for determining such, (ii) the purchase price of the shares, if any, and the means of payment for the shares, (iii) the Performance Criteria, if any, and level of achievement of such Performance Criteria that shall determine the number of
shares granted, issued, retainable and/or vested, (iv) the terms and conditions on the grant, issuance and/or forfeiture of the shares, and (v) such further terms and conditions as may be determined from time to time by the Committee, in
each case not inconsistent with this Plan. A Participant that is the holder of a Restricted Stock Unit Award shall not be entitled to shareholder rights with respect to the Restricted Stock Units, including the right to vote such shares represented
by the a Restricted Stock Unit or to receive dividends. Any dividend equivalents awarded with respect to a Restricted Stock Unit shall be subject to the same restrictions on transferability and forfeiture as the Restricted Stock Units with respect
to which the dividend equivalent is paid. A Restricted Stock Unit may be settled in cash or Common Stock, as determined by the Committee, with the amount of the cash payment based on the Fair Market Value of the shares of Common Stock at the time of
vesting. Any such settlements may be subject to such conditions, restrictions and contingencies as the Committee shall establish. 
 c.
Vesting of Restricted Stock Unit. At the time of the grant of a Restricted Stock Unit, the Committee shall establish a vesting date or vesting dates with respect to the shares of Common Stock covered by such Restricted Stock Unit,
which vesting dates may be based upon the passage of time and/or the satisfaction of Performance Criteria or other conditions as deemed appropriate by the Committee; provided, that all Awards of Restricted Stock Units, subject to and except
as provided in Sections 11(f), 11(j), 11(l) and 13, shall have a minimum vesting period of no less than one (1) year. 
 8. Phantom Stock. 

a. General. The Committee may grant Awards entitling recipients to receive, in cash or shares, the Fair Market Value of
shares of Common Stock (“Phantom Stock”) upon the satisfaction of one or more specified conditions. 
 b. Terms
and Conditions. Subject to Section 8(c), the Committee shall determine the terms and conditions of a Phantom Stock Award, including, but not limited to (i) the number of shares subject to or represented by such Phantom Stock Award or
a formula for determining such, (ii) the purchase price of the shares, if any, and the means of payment for the shares, (iii) the Performance Criteria, if any, and level of achievement of such Performance Criteria that shall determine the
number of shares granted, issued, retainable and/or vested or the amount of cash payable, (iv) the terms and conditions on the grant, issuance and/or forfeiture of the shares or Phantom Stock Award, and (v) such further terms and
conditions as may be determined from time to time by the Committee, in each case not inconsistent with this Plan. A Participant may not vote the shares represented by a Phantom Stock Award. Any settlements of Phantom Stock Awards may be subject to
such conditions, restrictions and contingencies as the Committee shall establish. 
 c. Vesting of Phantom Stock. At
the time of the grant of a Phantom Stock Award, the Committee shall establish a vesting date or vesting dates with respect to such Phantom Stock Award; provided that all Phantom Stock Awards, subject to and except as provided in Sections 11(f),
11(j), 11(l) and 13, shall have a minimum vesting period of no less than one (1) year. The Committee may establish vesting dates based upon the passage of time and/or the satisfaction of Performance Criteria or other conditions as deemed
appropriate by the Committee. 
 9. Other Stock-Based Awards. 

The Committee shall have the right to grant other Awards based upon the Common Stock and having such terms and conditions as the Committee may
determine, including, without limitation, the grant of shares based upon certain conditions and/or Performance Criteria, the grant of securities convertible into Common Stock and the grant of stock units. The Committee shall determine the terms and
conditions of any such Awards, including, but not limited to (i) the number of shares subject to such Award or a formula for determining such, (ii) the purchase price of the shares, if any, and the means of payment for the shares,
(iii) the 

  
 5 

 
Performance Criteria, if any, and level of achievement of such Performance Criteria that shall determine the number of shares granted, issued, retainable and/or vested, (iv) the terms and
conditions on the grant, issuance and/or forfeiture of the shares or Award, and (v) such further terms and conditions as may be determined from time to time by the Committee, in each case not inconsistent with this Plan. At the time of the
grant of an Award under this Section 9, the Committee shall establish a vesting date or vesting dates with respect to such Award, which vesting date may be based upon the passage of time and/or the satisfaction of Performance Criteria or other
conditions as deemed appropriate by the Committee; provided, that all Full Value Awards, subject to and except provided in Sections 11(f), 11(j), 11(l) and 13,granted under this Section 9 shall have a minimum vesting period of no less
than one (1) year. 
 10. Cash Awards. 

a. Grants. The Committee may grant cash awards (each, a “Cash Award”), either alone, in addition to, or
in tandem with other Awards granted under the Plan. 
 b. Terms and Conditions. The Committee shall determine the terms
and conditions of any such Cash Award. From time to time, the Committee shall establish administrative rules and procedures governing the administration of Cash Awards. 

c. Variable Compensation Awards. A Cash Award that the Committee intends to be a “Variable Compensation
Award” subject to Section 162(m) of the Code, provides a variable compensation payment each year to the Company’s executive officers and certain eligible senior employees each year based on certain Performance Criteria that may
include, among other criteria, overall corporate and/or individual business group’s or division’s performance during the prior fiscal year, as determined by the Committee. Variable Compensation Awards are calculated based on a percentage
of the Participant’s base annual salary (“Variable Compensation Factor”) and start at 5% for new Participants. Variable Compensation Factors are reviewed annually and typically do not exceed 100%. A newly hired executive
officer or employee, who is approved for eligibility for Variable Compensation Awards, will be eligible to receive a Variable Compensation Award for their first year of employment, pro-rated from the date of
hire. The Committee may rely upon the recommendation of the Company’s senior management in granting Variable Compensation Awards to eligible Participants who do not constitute executive officers of the Company, including as to the amount and
terms of any such Awards and the satisfaction of Performance Criteria. No Participant may be granted Variable Compensation Awards that would result in a payment of more than $3 million during any one fiscal year. 

11. General Provisions Applicable to Awards. 

a. Transferability of Awards. Except as the Committee may otherwise determine or provide in an Award, Awards shall not be
sold, assigned, transferred, pledged or otherwise encumbered by the person to whom they are granted, either voluntarily or by operation of law, except by will or the laws of descent and distribution, and, during the life of the Participant, shall be
exercisable only by the Participant, provided, however, that Nonstatutory Stock Options may be transferred to a grantor-retained annuity trust or a similar estate-planning vehicle in which the trust is bound by all provisions of the Option
which are applicable to the Participant. References to a Participant, to the extent relevant in the context, shall include references to authorized transferees of such an Option. 

b. Documentation. Each Award granted under the Plan, with the exception of Cash Awards, shall be evidenced by a written
Award agreement in such form as the Committee shall from time to time approve. Award agreements shall comply with the terms and conditions of the Plan and may contain such other provisions not inconsistent with the terms and conditions of the Plan
as the Committee shall deem advisable. In the case of an Incentive Stock Option, the Award agreement shall contain, or refer to, such provisions relating to exercise and other matters as are required of “incentive stock options” under the
Code. Award agreements may be evidenced by an electronic transmission (including an e-mail or reference to a website or other URL) sent to the Participant through the Company’s normal process for
communicating electronically with its employees. As a condition to receiving an Award, the Committee may require the Participant to affirmatively accept the Award and agree to the terms and conditions set forth in the Award agreement by physically
and/or electronically executing the Award agreement or by otherwise physically and/or electronically acknowledging such acceptance and agreement. With or without such affirmative acceptance, however, the Committee may prescribe conditions (including
the exercise or attempted exercise of any benefit conferred by the Award) under which the proposed Participant may be deemed to have accepted the Award and agreed to the terms and conditions set forth in the Award agreement. 

c. Committee Discretion. The terms of each type of Award need not be identical, and the Committee need not treat
Participants uniformly. 
 d. Performance Criteria. For purposes of this Plan, the term “Performance
Criteria” shall mean any one or more of the following performance criteria, applied to either the Company as a whole or to a division, business unit or Subsidiary, and measured either annually or cumulatively over a period of years, on an
absolute basis or relative to a pre-established target, to previous years’ results or to a designated comparison group, in each case as specified by the Committee in the Award: cash flow; earnings per

  
 6 

 
share; earnings before interest, taxes and amortization; return on equity; total shareholder return; share price performance; return on capital; return on assets or net assets; revenue; orders;
product gross margins, including by customer; income or net income; operating income or net operating income; operating profit or net operating profit; income from operations less restructuring and other, net, amortization of acquired intangible
assets, acquisition and divestiture related charges or credits, pension actuarial gains and losses, and other non-recurring gains and charges; operating margin or profit margin; return on operating revenue;
return on invested capital; market segment share; customer wins or design ins; product release schedules; new product innovation; product cost reduction; brand recognition/acceptance; product ship targets; process improvement results; verification
of business strategy and/or business plan; improvement of strategic position; adaptation to changes in the marketplace or environment; or customer satisfaction. If the Award so provides, the Committee may appropriately evaluate achievement against
Performance Criteria to take into account any of the following events that occurs during a performance period: asset write-downs; litigation or claim judgments or settlements; the effect of changes in tax law; accounting principles or other such
laws or provisions affecting reported results; accruals for reorganization and restructuring programs and any extraordinary non-recurring charges or other events. The Committee may prescribe the foregoing
criteria either individually or in combination. The Committee’s determination of the achievement of any Performance Criteria shall be conclusive. At the time of the grant of any Full Value Award subject to this Section 11(d), the Committee
shall establish a vesting date or vesting dates with respect to the shares of Common Stock covered by such Awards; provided that all Full Value Awards subject to this Section 11(d), subject to and except as provided in Sections 11(f), 11(j),
11(l) and 13, shall have a minimum vesting period of no less than one (1) year. 
 e. Termination of Status.
Except as otherwise specified herein, the Committee shall determine the effect on an Award of the disability, death, retirement, authorized leave of absence or other change in the employment or other status of a Participant and the extent to
which, and the period during which, the Participant, or the Participant’s legal representative, conservator, guardian or Designated Beneficiary, may exercise rights under the Award under such circumstances, subject to applicable law and the
provisions of the Code. 
 f. Acquisition or Liquidation of the Company. 

(i) Consequences of an Acquisition. If the Company is to be consolidated with or acquired by another
entity in a merger or other reorganization in which the holders of the outstanding voting stock of the Company immediately preceding the consummation of such event shall, immediately following such event, hold, as a group, less than a majority of
the voting securities of the surviving or successor entity, or in the event of a sale of all or substantially all of the Company’s assets or otherwise (each, an “Acquisition”), the Committee or the board of directors of any
entity assuming the obligations of the Company hereunder (the “Successor Committee”), shall, as to outstanding Awards, either (A) make appropriate provision for the continuation of such Awards by substituting on an equitable
basis for the shares then subject to such Awards either (1) the consideration payable with respect to the outstanding shares of Common Stock in connection with the Acquisition, (2) shares of stock of the surviving or successor corporation
or (3) such other securities as the Committee or the Successor Committee deems appropriate, the Fair Market Value of which shall not materially exceed the Fair Market Value of the shares of Common Stock subject to such Awards immediately
preceding the Acquisition; or (B) upon written notice to the Participants, provide that all Awards must be exercised, to the extent then exercisable or to be exercisable as a result of the Acquisition, within a specified number of days of the
date of such notice, at the end of which period the Awards shall terminate; or (C) terminate all Awards in exchange for a cash payment equal to the excess, if any, of the Fair Market Value of the shares subject to such Awards (to the extent
then exercisable or to be exercisable as a result of the Acquisition) over the exercise price thereof, if any; or (D) in the case of Awards that may be settled in whole or in part in cash, provide for equitable treatment of such Awards. 

(ii) Substitution of Awards Upon Certain Events. In connection with a merger or consolidation of an entity
with the Company or the acquisition by the Company of property or stock of an entity, the Committee may grant Awards under the Plan in substitution for stock and stock-based awards issued by such entity or an affiliate thereof. The substitute Awards
shall be granted on such terms and conditions as the Committee considers appropriate in the circumstances. 
 (iii)
Liquidation or Dissolution. In the event of the proposed liquidation or dissolution of the Company, each Award, except for Cash Awards already earned, to the extent not then exercised or vested, will terminate immediately prior to
the consummation of such proposed action or at such other time and subject to such other conditions as shall be determined by the Committee. 

g. Withholding. Each Participant shall pay to the Company, or make provisions satisfactory to the Company for payment, of
any taxes required by law to be withheld in connection with Awards to such Participant no later than the date of the event creating the tax withholding obligation. Participants may elect to satisfy such tax withholding obligations by authorizing the
Company to withhold shares of Common Stock from the Award creating the tax obligation, valued at their Fair Market Value. If the 

  
 7 

 
withholding of shares for legal or accounting reasons is problematic and a Participant does not otherwise satisfy such tax withholding obligations, the Company may, to the extent permitted by
law, deduct any such tax obligations from any payment of any kind otherwise due to a Participant. 
 h. Amendment of
Awards. The Committee may amend, modify or terminate any outstanding Award including, but not limited to, substituting therefor another Award of the same or a different type, changing the date of exercise or realization, the vesting
provisions (subject to the minimum vesting requirements set forth herein), Performance Criteria, or level of achievement of Performance Criteria, and converting an Incentive Stock Option to a Nonstatutory Stock Option; provided that, except
as otherwise provided in Section 11(f)(i), the Participant’s consent to such action shall be required unless the Committee determines that the action, taking into account any related action, would not materially and adversely affect the
Participant; provided, further, that subject to Section 3(c), an Option may not be amended subsequent to its issuance either to reduce the price at which such previously issued Option is exercisable or to extend the period of time for which
such previously-issued Option shall be exercisable beyond ten (10) years unless such amendment is approved by the Company’s shareholders. Furthermore, no Option shall be canceled and replaced with Options having a lower exercise price
unless such cancellation and exchange is approved by the Company’s shareholders. The Amendment of all Awards shall be subject to Section 11(n). 

i. Conditions on Delivery of Stock. The Company will not be obligated to deliver any shares of Common Stock pursuant to
the Plan or to remove restrictions from shares previously delivered under the Plan until (i) all conditions of the Award have been met or removed to the satisfaction of the Company, (ii) in the opinion of the Company’s counsel, all
other legal matters in connection with the issuance and delivery of such shares have been satisfied, including any applicable securities laws and any applicable stock exchange or stock market rules and regulations, (iii) the Participant has
executed and delivered to the Company such representations or agreements as the Company may consider appropriate to satisfy the requirements of any applicable laws, rules or regulations, and (iv) the Participant has paid to the Company, or made
provisions satisfactory to the Company for payment of, any taxes required by law to be withheld in connection with the Award. 
 j.
Acceleration. The Committee may at any time provide (i) that Awards that may be settled in whole or in part in cash may become immediately exercisable in full or in part, and (ii) in connection with the disability or
death of a Participant or in connection with an event contemplated by Section 11(f)(i), that any Award shall become exercisable in full or in part or shall be free of some or all restrictions or the risk of forfeiture. The Committee may take the
actions contemplated by the preceding sentence despite the fact that such actions may (x) cause the application of Sections 280G and 4999 of the Code if an event contemplated by Section 11(f)(i) occurs, or (y) disqualify all or part of an
Option as an Incentive Stock Option. In the event of the acceleration of the exercisability of one or more outstanding Options, including pursuant to Section 11(f)(i), the Committee may provide, as a condition of accelerated exercisability of any or
all such Options, that the Common Stock or other substituted consideration, including cash, as to which exercisability has been accelerated shall be restricted and subject to forfeiture back to the Company at the election of the Company at the cost
thereof upon termination of employment or other relationship, with the timing and other terms of the vesting of such restricted Common Stock or other consideration being not less favorable to the Participant than the timing and other terms of the
superseded vesting schedule of the related Option. 
 k. Reserved. 

l. Exception to Minimum Vesting Periods and Acceleration Limitations. The Committee may grant or accelerate the vesting
of Awards with respect to up to 5% of the maximum, aggregate shares of Common Stock authorized for issuance hereunder in a manner that does not comply with the minimum vesting periods set forth in Sections 4(g), 5(d), 6(c), 7(c), 8(c), 9, 11(d) and
13 or that is not otherwise permitted under the vesting acceleration limitations in Section 11(j). 
 m. Compliance with Section
409A. Any other provision of the Plan or any Award to the contrary notwithstanding, the Plan and every Award hereunder shall be construed, administered and enforced as necessary to comply with applicable requirements of Section 409A of the Code
and the Treasury and IRS rulings and regulations issued thereunder, so that no Participant shall (without such Participant’s express written consent) incur any of the additional tax or interest liabilities of Section 409A(a)(B) of the Code with
respect to any Award. The Plan and each Award are hereby modified and limited as necessary to comply with applicable requirements of Section 409A. 

n. Compliance with Limitations on Repricing. Unless such action is approved by the Company’s shareholders, the Company may
not, except as provided for under Section 3(c)(i) amend any outstanding Option or SAR granted under the Plan to provide an exercise or measurement price per share that is lower than the then-current exercise or measurement price per share of such
outstanding Option or SAR; (ii)cancel any outstanding option or stock appreciation right (whether or not granted under the Plan) and grant in substitution new Awards under the Plan (other than Awards granted pursuant to Section 11(f)(ii)); (iii)
cancel in exchange for a cash payment any outstanding Option or SAR with an exercise or measurement price per share above the then-current Fair Market Value; or (iv) take any action under the Plan that constitutes a “repricing” of an
Award with the meaning of the rules of the New York Stock Exchange, or other exchange on which the Company’s Common Stock is traded.

 12. Foreign Jurisdictions. 

To the extent that the Committee determines that the material terms set by the Committee or imposed by the Plan preclude the achievement of the
material purposes of the Plan in jurisdictions outside the United States, the Committee will have the authority and discretion to modify those terms and provide for such other terms and conditions as the Committee determines to be necessary,
appropriate or desirable to accommodate differences in local law, policy or custom or to facilitate administration of the Plan. The Committee may adopt or approve sub-plans, appendices or supplements to, or
amendments, restatements or alternative versions of, the Plan as it may consider necessary, appropriate or desirable for such purpose, without thereby affecting the terms of the Plan as in effect for any other purpose. The special terms and any
appendices, supplements, amendments, restatements or alternative versions, however, shall not include any provisions that are inconsistent with the terms of the Plan as then in effect, unless the Plan could have been amended to eliminate such
inconsistency without further approval by the shareholders. The Committee shall also have the authority and discretion to delegate the foregoing powers to appropriate officers of the Company. 

13. Grant of Awards to Non-Employee Directors. 

Each person who is a member of the Board of Directors and who is not an employee of the Company (each, a “Non-Employee Director”) shall be automatically granted Awards having a Fair Market Value or exercisable for shares having a Fair Market Value, as the case may be, on the day of such grant as follows: 

a. on the date such Non-Employee Director is first elected or appointed to the Board of
Directors (other than pursuant to an election at an annual meeting of shareholders, in which case, paragraph b and only paragraph b below shall apply) equal to the value of the Automatic Annual Grant, as prorated daily to reflect the period between
the directors date of election or appointment and the date of the next Automatic Annual Grant; and 
 b. on the date in each year
which is the earlier of (i) the date that the annual meeting of shareholders is held and (ii) the last Thursday in May, equal to a dollar amount approved by the Board of Directors not to exceed $200,000 (“Automatic Annual
Grant”). 
 Awards granted under this Section 13 may be any of the following: Restricted Stock Units, Restricted Stock,
Nonstatutory Stock Options, SARs, or cash, or a combination of the foregoing. Awards granted under the Plan shall be in addition to the annual Board and Committee cash retainers paid by the Company to the
Non-Employee Directors. The type of Awards granted under this Section 13 shall be determined, in each instance, at the Committee’s discretion (subject to the foregoing limitations). The number of
shares, if any, covered by Awards granted under this Section 13 shall be subject to adjustment in accordance with the provisions of Section 3(c) of this Plan. Subject to and except as provided in Sections 11(f), 11(j) and 11(l), an Award of
Restricted Stock, Restricted Stock Units, Options or SARS granted pursuant to this Section 13 shall have a minimum vesting period that extends until the earlier of one year from the grant of the Award or the date the next annual meeting of
shareholders is held following the grant of the Award, and shall expire on the date which is ten (10) years after the date of grant of such Award. Cash Awards granted pursuant to this Section 13 may, at the Committee’s discretion, be
immediately exercisable or paid in their entirety on the date of grant. 
 14. Miscellaneous. 

a. Definitions. 

(i) “Company” for purposes of eligibility under the Plan, shall include Teradyne, Inc. and any present or
future subsidiary corporations of Teradyne, Inc., as defined in Section 424(f) of the Code (a “Subsidiary”), and any present or future parent corporation of Teradyne, Inc., as defined in Section 424(e) of the Code. For purposes of
Awards other than Incentive Stock Options, the term “Company” shall include any other entity in which the Company has a direct or indirect significant interest, as determined by the Committee in its sole discretion. 

(ii) “Code” means the Internal Revenue Code of 1986, as amended, and any regulations promulgated thereunder.

 (iii) “Employee” for purposes of eligibility under the Plan shall include a person to whom an offer of

 9 

 (iv) “Fair Market Value” of the Company’s Common Stock on
any date means (i) the closing price (on that date) of the Common Stock on the principal national securities exchange on which the Common Stock is traded, if the Common Stock is then traded on a national securities exchange; or (ii) the
average of the closing bid and asked prices last quoted (on that date) by an established quotation service for over-the-counter securities, if the Common Stock is not
then traded on a national securities exchange; or (iii) if the Common Stock is not publicly traded, the fair market value of the Common Stock as determined by the Committee after taking into consideration all factors which it deems appropriate,
including, without limitation, recent sale and offer prices of the Common Stock in private transactions negotiated at arm’s length; provided, that, in all events the Fair Market Value shall represent the Committee’s good faith
determination of the fair market value of the Common Stock. The Committee’s determination shall be conclusive as to the Fair Market Value of the Common Stock. 

(v) “Full Value Awards” means Restricted Stock, Restricted Stock Units and Awards other than (a) Options
or (b) SARs or (c) Cash Awards or (d) other stock-based Awards for which the Participant pays the intrinsic value (whether directly or by forgoing a right to receive a cash payment from the Company). 

b. Legal Consideration for Issuance of Shares. Unless otherwise determined by the Committee, in the case of Awards of Restricted
Stock, Restricted Stock Units, or Awards that are settled in whole or in part with shares of Common Stock, to the extent such Awards do not otherwise require the payment by the Participant of cash consideration that exceeds the par value of the
shares of Common Stock received in connection therewith, the services rendered or to be rendered by the Participant shall satisfy the legal requirement of payment of par value for such shares of Common Stock. 

c. No Right To Employment or Other Status. No person shall have any claim or right to be granted an Award, and the grant of an
Award shall not be construed as giving a Participant the right to continued employment or any other relationship with the Company. The Company expressly reserves the right at any time to dismiss or otherwise terminate its relationship with a
Participant free from any liability or claim under the Plan. 
 d. No Rights As Shareholder. Subject to the provisions of the
applicable Award, no Participant or Designated Beneficiary shall have any rights as a shareholder with respect to any shares of Common Stock to be distributed with respect to an Award until becoming the record holder thereof. 

e. Effective Date and Term of Plan. The Plan shall become effective on the date on which it is approved by the shareholders of
the Company (the “Effective Date”). No Awards shall be granted under the Plan after May 12, 2025, but Awards previously granted may extend beyond that date. 

f. Amendment of Plan. The Committee may amend this Plan at any time, provided that any material amendment to the Plan will not
be effective unless approved by the Company’s shareholders. For this purpose, a material amendment is any amendment that would (i) other than pursuant to Section 3(c), materially increase either the aggregate number of shares of Common
Stock available for issuance under the Plan; or the maximum number of shares of Common Stock issuable in one fiscal year to a Participant; (ii) expand or limit the class of persons eligible to receive Awards or otherwise participate in the
Plan; (iii) subject to Section 3(c), reduce the price at which a previously-issued Option is exercisable or extend the period of time for which a previously-issued Option shall be exercisable beyond ten (10) years; (iv) subject to Section
11(f) and Section 11(j), amend the minimum vesting provisions of Full Value Awards; or (v) require shareholder approval pursuant to the requirements of the NYSE and/or any other exchange on which the Company is then listed or pursuant to
applicable law. 
 g. Governing Law. The provisions of the Plan and all Awards made hereunder shall be governed by and
interpreted in accordance with the laws of The Commonwealth of Massachusetts, exclusive of reference to rules and principles of conflicts of law.

PERFORMANCE-BASED RESTRICTED STOCK UNIT TERMS FOR U.S. RECIPIENTS 

1. Award Grant, Vesting and Transfer 

(a) Award Grant. Teradyne, Inc. hereby grants to the recipient an award (this “Award”) of
performance-based restricted stock units (the “RSUs”) under the Teradyne, Inc. 2006 Equity and Cash Compensation Incentive Plan (the “Plan”). The RSUs represent the right of the recipient to receive that number of
shares of Teradyne common stock set forth in the Notice of Performance-Based Restricted Stock Unit Grant and Terms (the “Notice of Grant”) attached hereto upon satisfaction of the terms set forth in this Agreement. This Award is
governed by and subject to the terms of the Plan, the Notice of Grant and this Agreement. 
 Capitalized terms used but not otherwise
defined herein will have the meaning set forth in the Notice of Grant or the Plan. In the event of any inconsistencies or differences between the Plan and these terms, the Plan shall prevail. The terms governing this Award are intended to
comply with all applicable laws and regulations. 
 (b) Vesting of Award. None of this grant will be vested on the
Effective Date. The number of Actual Performance-Based Shares that will be allowed to vest is uncertain at the time of the grant but is expected to be determined near the three-year anniversary of the grant, based on the determination by the
Committee or Teradyne’s Board of Directors of the Performance Percentage. The “Performance Percentage” is a percentage ranging from 0-200% determined using Performance Criteria approved by the
Committee or Teradyne’s Board of Directors for the grant. The Performance Percentage shall be multiplied against the Target Performance-Based Shares granted to derive the number of Actual Performance-Based Shares. Except as provided in
(c) below, this Award shall vest with respect to 100% of the Actual Performance-Based Shares on the later of the third anniversary of the Effective Date or the date the Board determines the number of Actual Performance-Based Shares. The portion
of the grant that is not allowed to vest will be forfeited. Subject to the terms of the Plan, the Committee shall have the right to accelerate the date that any installment of this Award becomes vested, including, but not limited to, events such as
disability, death or upon the acquisition of control of Teradyne by another entity. 
 (c) This Award will not vest further after
termination of employment or other business relationship except in limited certain circumstances. This Award will not vest after the recipient’s employment or other business relationship with Teradyne or its Subsidiaries ends,
regardless of the reason, provided, however, that if the recipient’s employment or other business relationship with Teradyne or one of its Subsidiaries ends prior to the determination of the Performance Percentage on account of
(1) permanent disability or death or (2) retirement or termination, other than for cause, after attaining both at least age sixty, and at least ten years of service, then (a) one-hundred percent
of the Actual Performance-Based Shares under any Award granted at least 365 calendar days prior to the permanent disability, death, retirement or termination without cause shall vest on the date the Performance Percentage is determined by the
Committee or the Board of Directors and (b) a pro-rated portion of the Actual Performance-Based Shares under any Award granted within 365 calendar days of the permanent disability, death, retirement or
termination without cause based on the number of days of employment or other business relationship during the 365 calendar day period from the grant date shall vest on the date the Performance Percentage is determined by the Committee or the Board
of Directors. 
 Employment or another business relationship shall be considered as continuing uninterrupted during any bona fide leave of
absence (such as those attributable to illness or military obligations) provided that the period of such leave does not exceed 90 days or, in the case of an employee, if longer, any period during which the employee’s right to reemployment is
guaranteed by statute. A bona fide leave of absence with the written approval of the Committee shall not be considered an interruption of employment or other business relationship, provided that such written approval contractually obligates Teradyne
or a Subsidiary to continue the employment or other business relationship of the recipient after the approved period of absence. 

(d) No rights as stockholder; Issuance. The recipient shall not have any rights as a stockholder in, to or with respect to any
shares which may be covered by this Award (including but not limited to the right to vote or to receive dividends) until this Award is settled by issuance of shares to the recipient. All shares issued in respect of this Award will be transferred or
issued to the recipient (or his or her estate, in the event of his or her death) as soon as is practicable after the date the Actual Performance-Based Shares vest but, in any event, within 2 1/2 months following the calendar year in which the Actual Performance-Based Shares become vested (or any earlier date, after vesting, as
required to avoid characterization as non-qualified deferred compensation under Section 409A of the Code). Teradyne will not be required to transfer or issue any shares upon vesting of the Actual
Performance-Based Shares until arrangements 

  
 2 

 
satisfactory to it have been made by the recipient to address any Tax-Related Items (as defined in Section 4 below) which might arise by reason of the
vesting of the Actual Performance-Based Shares and/or transfer or issuance of shares. 
 (e) This Award may not be assigned or
transferred. Other than as provided in Section 11(a) of the Plan, this Award is not assignable or transferable (except by will or the laws of descent and distribution). 

2. Capital Changes and Business Succession. Section 3(c) of the Plan contains provisions for adjusting (or
substituting) the number and class of securities, vesting schedule, and other terms of outstanding stock-based awards granted under the Plan if a recapitalization, stock split, merger, or other specified event occurs, and the Committee determines
that an adjustment (or substitution) is appropriate. In that event, the recipient of this Award will be notified of the adjustment (or substitution), if any, to this Award. 

3. Employment or Business Relationship. Granting this Award does not imply any right of continued employment or
business relationship with Teradyne or its Subsidiaries, and does not affect the right of the recipient, Teradyne or its Subsidiaries to terminate the recipient’s employment or a business relationship at any time. 

4. Tax Obligations. 

(a) Responsibility for Taxes. The recipient acknowledges that, regardless of any action taken by Teradyne or, if
different, the recipient’s employer (the “Employer”), the ultimate liability for all income tax, social insurance, payroll tax, fringe benefits tax, payment on account or other
tax-related items related to the recipient’s participation in the Plan and legally applicable to the recipient (“Tax-Related Items”), is and
remains the recipient’s responsibility and may exceed the amount actually withheld by Teradyne or the Employer. The recipient further acknowledges that Teradyne and/or the Employer (1) make no representations or undertakings regarding the
treatment of any Tax-Related Items in connection with any aspect of this Award, including, but not limited to, the grant, vesting or settlement of the RSUs, the subsequent sale of shares acquired pursuant to
such settlement and the receipt of any dividends or other distributions, and (2) do not commit to and are under no obligation to structure the terms of the grant or any aspect of this Award to reduce or eliminate the recipient’s liability
for Tax-Related Items or achieve any particular tax result. Further, if the recipient is subject to Tax-Related Items in more than one jurisdiction between the Effective
Date and the date of any relevant taxable or tax withholding event, as applicable, the recipient acknowledges that Teradyne and/or the Employer (or former employer, as applicable) may be required to withhold or account for Tax-Related Items in more than one jurisdiction. 
 (b) Tax Withholding. Prior to any
relevant taxable or tax withholding event, as applicable, the recipient agrees to make adequate arrangements satisfactory to Teradyne and/or the Employer to satisfy all Tax-Related Items. The recipient
authorizes Teradyne or its respective agents to satisfy the obligations with regard to all Tax-Related Items by withholding in shares to be issued upon settlement of the RSUs; provided, however, that the total
Tax-Related Items withholding where shares are being used to satisfy such tax obligations cannot exceed Teradyne’s minimum statutory withholding obligations. If the obligation for Tax-Related Items is satisfied by withholding in shares, for tax purposes, the recipient is deemed to have been issued the full number of shares subject to the vested RSUs, notwithstanding that a number of the
shares are held back solely for the purpose of paying the Tax-Related Items. In the event that such withholding in shares is problematic under applicable tax or securities law or has materially adverse
accounting consequences, by the recipient’s acceptance of this Award, the recipient authorizes and directs Teradyne and any brokerage firm determined acceptable to Teradyne to sell on the recipient’s behalf a whole number of shares from
those shares issuable to the recipient as Teradyne determines to be appropriate to generate cash proceeds sufficient to satisfy the obligation for Tax-Related Items. If withholding is performed from
proceeds from the sale of shares acquired upon vesting of the RSUs, Teradyne shall withhold for Tax-Related Items at minimum applicable rates. Alternatively, Teradyne, in its sole discretion and pursuant
to such procedures as it may specify from time to time, may permit or require the recipient to satisfy his or her obligations for Tax-Related Items, in whole or in part (without limitation) by delivery of
cash or check to Teradyne or the Employer, or Teradyne or the Employer may withhold from the recipient’s wages or other compensation. 

5. Compliance with Laws. Shares to be issued under this Award are currently registered under the United States Securities Act of
1933, as amended. If such registration is not in effect at the time of vesting, the recipient will be required to represent to Teradyne that he or she is acquiring such shares as an investment and not with a view to the sale of those shares.
Notwithstanding any other provision of the Plan or the Agreement, unless there is an available exemption from any registration, qualification or other legal requirement applicable to the shares of common stock, Teradyne shall not be required to
deliver any shares of common stock issuable upon settlement of the RSUs prior to the completion of any registration or qualification of the shares under any local, state, federal or foreign securities or exchange control law or under rulings or
regulations of the United States Securities and Exchange Commission (“SEC”) 

  
 3 

 
or of any other governmental regulatory body, or prior to obtaining any approval or other clearance from any local, state, federal or foreign governmental agency, which registration,
qualification or approval Teradyne shall, in its absolute discretion, deem necessary or advisable. The recipient understands that Teradyne is under no obligation to register or qualify the shares with the SEC or any state or foreign securities
commission or to seek approval or clearance from any governmental authority for the issuance or sale of the shares. Further, the recipient agrees that Teradyne shall have unilateral authority to amend the Plan and the Agreement without
the recipient’s consent to the extent necessary to comply with securities or other laws applicable to issuance of shares. 
 6.
Code Section 409A. This Award is intended to be exempt from the application of Section 409A of the Code, and any ambiguities herein will be interpreted to so comply. Teradyne reserves the right, to the extent Teradyne deems
necessary or advisable in its sole discretion, to amend or modify the terms of this Award (or the Plan) or adopt other policies and procedures (including amendments, policies and procedures with retroactive effect), or take other actions, including
any amendments or actions that would result in a reduction to the benefit payable under this Award, in each case, without the consent of the recipient of the Award, as may be necessary to ensure that all vesting or settlement provided under this
Award are made in a manner that complies with Section 409A of the Code or to mitigate any additional tax, interest and/or penalties or other adverse tax consequences that may apply under Section 409A of the Code if compliance is not practical;
provided, however, that nothing in this Section 6 creates an obligation on the part of Teradyne to modify the terms of this Award or the Plan. In that light, Teradyne makes no representation that the terms of this Award will comply with
Section 409A of the Code or that the settlement under Award will not be subject to taxes, interest and penalties or other adverse tax consequences under Section 409A of the Code. In no event whatsoever shall Teradyne or any of its affiliates be
liable to the recipient of this Award or any other party for any additional tax, interest, penalties or other liability that may be imposed on the recipient of this Award by Section 409A of the Code or for any action taken by Teradyne with respect
thereto. 
 7. Governing Law and Venue. The Award and the provisions of this Agreement are governed by, and subject to, the
laws of the Commonwealth of Massachusetts, without regard to the conflict of law provisions, as provided in the Plan. For purposes of litigating any dispute that arises under this Award or this Agreement, the parties hereby submit to and
consent to the jurisdiction of the Commonwealth of Massachusetts, agree that such litigation shall be conducted in the courts of Middlesex County, or the federal courts for the United States for the District of Massachusetts,
where this grant is made and/or to be performed. 
 8. Electronic Delivery and Acceptance. Teradyne may, in its sole
discretion, decide to deliver any documents related to current or future participation in the Plan by electronic means. The recipient hereby consents to receive such documents by electronic delivery and agrees to participate in the Plan through
an on-line or electronic system established and maintained by Teradyne or a third party designated by Teradyne. 

9. Severability. The provisions of this Agreement are severable and if any one or more provisions are determined to
be illegal or otherwise unenforceable, in whole or in part, the remaining provisions shall nevertheless be binding and enforceable. 

10. Imposition of Other Requirements. Teradyne reserves the right to impose other requirements on the recipient’s
participation in the Plan, on the RSUs and on any shares of common stock acquired under the Plan, to the extent Teradyne determines it is necessary or advisable for legal or administrative reasons, and to require the recipient to sign any additional
agreements or undertakings that may be necessary to accomplish the foregoing. 
 11. Waiver. The recipient acknowledges that a
waiver by Teradyne of breach of any provision of this Agreement shall not operate or be construed as a waiver of any other provision of this Agreement, or of any subsequent breach by the recipient or any other recipient. 

12. No Advice Regarding Grant. Teradyne is not providing any tax, legal or financial advice, nor is Teradyne making
any recommendations regarding the recipient’s participation in the Plan, or the recipient’s acquisition or sale of the underlying shares of common stock. The recipient is hereby advised to consult with his or her own personal tax, legal
and financial advisors regarding his or her participation in the Plan before taking any action related to the Plan.
