Deferral Plan for Non-Employee Directors



 Exhibit 10.2 
 Teradyne, Inc. 
 Deferral Plan for Non-Employee Directors 
 (Restated Effective January 1, 2005) 
 WHEREAS, Teradyne,
Inc. (the “Company”) has established the Teradyne, Inc. Deferral Plan for Non-Employee Directors, effective January 1, 2001, and amended as of March 1, 2003, (the “Prior Plan”) which provides each Non-Employee Director
of the Company with an election to defer receipt of his or her Compensation from the Company; and 
 WHEREAS, the Company wishes to amend and restate such
Prior Plan to comply with Section 409A with respect to Compensation deferred after December 31, 2004 and expand the elections permitted under the Prior Plan. 
 NOW, THEREFORE, the Company hereby amends and restates the Prior Plan to read in its entirety as set forth below, as so amended and restated (the “Plan”). The Plan has been operated in compliance with
Section 409A since January 1, 2005 with respect to amounts subject to Section 409A. This amendment and restatement is intended to memorialize any changes in operation of the Plan as of that date as required by Section 409A. All
other changes are effective as otherwise provided herein. 
  

	1.	Eligibility. 

 Each person who is a Non-Employee Director on
December 1, 2004 is eligible to participate in the Plan for the Plan Year beginning January 1, 2005. All other persons who are Non-Employee Directors on December 1 of any calendar year beginning in or after December 1, 2005 are
eligible to participate in the Plan Year beginning the immediately following January 1. A Non-Employee Director who is eligible to participate may become a Participant by making a deferral election with respect to Compensation payable in the
following Plan Year under Section 2. Eligibility to participate in the Plan for any Non-Employee Director automatically ends upon the termination of the individual’s status as a member of the Board of Directors. If the Non-Employee
Director becomes an Employee then any deferral election for Compensation payable in the Plan Year in which such employment commences shall remain in effect for the balance of the Plan Year but no further deferral elections may be made under the
Plan. 
  

	2.	Participation. 

 A. Each Non-Employee Director who makes an election
to defer the receipt of Compensation for any Plan Year must complete a Deferral Election Form, no later than the December 1 prior to the first day of the Plan Year with respect to which it is intended to be effective and deliver such completed
form to the Company’s HR director or other designated Company Employee. A Deferral Election Form may be modified or withdrawn by the Participant prior to December 1 preceding the Plan Year to which it relates. The last completed form
delivered to the HR director prior to or on December 1 and not withdrawn as of that date, shall be considered the Deferral Election Form for the upcoming Plan Year and shall be irrevocable after such December 1. 
  

 -1- 








 B. Each Non-Employee Director who does not timely complete and deliver a Deferral Election Form for any Plan Year shall
not defer receipt of any Compensation for such Plan Year and shall receive any and all Compensation to which he or she is entitled during such Plan Year in accordance with the Company’s customary practices. 
  

	3.	Elections. 

 The Deferral Election Form for each Plan Year Deferral
shall include the following elections: 
 A. An election to defer all the cash Compensation or, effective for Plan Years beginning January 1, 2007, all
the Shares or both that are otherwise payable to the Non-Employee Director in the next Plan Year. 
 B. An election of the manner in which the cash portion
of the Plan Year Deferral shall be allocated under the terms of Section 4(B)(1), as amended from time to time. 
 C. An election as to whether the Plan
Year Deferral is payable, on distribution, in a lump sum or, effective for Plan Years beginning on or after January 1, 2007, such number of annual installments (up to a maximum of 15) as the Non-Employee Director elects. 
  

	4.	Accounting. 

 A. The Company or its designee shall establish an
account for each Participant for recordkeeping purposes only, including sufficient subaccounts to reflect all of Participant’s elections in Section 3 for all such Participant’s Plan Year Deferrals. The account and subaccounts are
intended only for the purposes of determining the amounts to be distributed to the Participant under the Plan. Grandfathered Accounts shall be subject only to the terms of the Plan which were in effect under the Prior Plan, unless the Board elects
at any time, to make them subject to the terms of the amended and restated Plan by a resolution to that effect. 
 B. The account and subaccount shall be
adjusted as follows: 
 1. Cash deferred by any Participant will be allocated, in accordance with the Participant’s election, to either (a) a
notional account, or (b) a Deferred Stock Unit account (“DSU Account”). 
 a. Notional Account. Any amount which the Participant has
allocated to a notional account, shall be credited with earnings, quarterly, at the rate in effect at the beginning of each Plan Year on 10 year Treasury Notes. 
 b. DSU Account. Any amount which the Participant has allocated to the DSU Account will be converted into a number of Deferred Stock Units on the date the cash amounts deferred would have been paid to the Participant. The number of
Deferred Stock Units credited to the Participant’s DSU Account with respect to each cash deferral shall be determined by dividing the cash amount deferred by the Fair Market Value of the Common Stock on such date. If any cash dividends are
subsequently declared with respect to the Common Stock then the cash that would 

  

 -2- 








 
have been paid to the Participant as dividends if he or she had owned the number of whole shares of Common Stock represented by the Deferred Stock Units
shall, on the date such dividend is paid, be credited to the notional account of the Participant with respect to the Plan Year Deferral to which such Deferred Stock Units relate and shall thereafter be credited with earnings as provided in
Section 4(B)(1)(a). 
 2. Any Shares deferred by the Participant shall be separately accounted for under this Section 4(B)(2), in a subaccount of
the DSU Account. The number of Shares deferred shall also be converted into Deferred Stock Units, crediting the Participant with one Deferred Stock Unit for each Share deferred. Any Shares which are not vested at the time they are credited to the
DSU Account shall be continue to vest in accordance with the terms of the applicable agreement evidencing the award of such Shares. Any cash dividends payable with respect to the deferred Shares shall be treated as specified in
Section 4(B)(1)(b) and shall vest in accordance with the terms applicable to the Shares. 
  

	5.	Voting and Dividend Rights in Deferred Stock Units. 

 No Participant
shall be entitled to any voting rights or to receive (except as provided in Section 4(B)) any dividends with respect to any amounts or Shares treated as converted into Deferred Stock Units. 
  

	6.	Distributions. 

 A. Generally. Distributions of each Plan
Year Deferral shall be made as a lump sum, or in installments, in accordance with the terms of the Deferral Election Form the Participant has completed with respect to the Plan Year Deferral. A Participant shall become entitled to distributions
following his or her separation from service as defined in Section 409A. Such distributions shall be made or commence within 90 days after the date of the Participant’s separation from service, subject to the provisions of
Section 6(F). If distributions are to be made in installments then each annual installment shall be made within 30 days before or after the anniversary of the first installment distribution, except that if the first installment is delayed in
accordance with Section 6(F), then each successive annual installment will be made within 90 days day following the anniversary of the Participant’s separation from service. 
 B. Lump Sum. Any distributions of a Plan Year Deferral to be made in a lump sum shall consist of (i) cash, which is an amount equal to the aggregate balance in the Participant’s notional account with
respect to such Plan Year Deferral on the distribution date, and (ii) that number of shares of Common Stock equal to the aggregate number of vested Deferred Stock Units with respect to such Plan Year Deferral in the Participant’s DSU
Account on the distribution date. Any unvested Deferred Stock Units shall be forfeited upon the Participant’s termination of service as a member of the Board of Directors. The cash and the shares of Common Stock may be distributed separately
and at different times within the 90 day payment period. 
 C. Installments. Each installment distribution of any Plan Year Deferral shall consist of
(i) such amount of cash as is determined by dividing the aggregate balance in the Participant’s notional account with respect to such Plan Year Deferral on the date of such installment 

  

 -3- 








 
distribution by the total number of remaining installment distributions elected by the Participant in his or her Deferral Election Form with respect to such
Plan Year Deferral and (ii) that number of shares of Common Stock equal to the aggregate number of vested Deferred Stock Units in the Participant’s DSU Account with respect to such Plan Year Deferral on the date of such installment
distribution divided by the total number of remaining installment distributions elected by the Participant in his or her Deferral Election Form with respect to such Plan Year Deferral; provided that the number of shares of Common Stock distributed
may be rounded up or down to the nearest one share for ease of administration. 
 D. Form of Distribution. Amounts allocated to the notional account
shall be distributed in cash and amounts allocated to DSU Account shall be distributed in shares of Common Stock. Shares of Common Stock distributed under the Plan shall be issued from either the 2006 Equity and Cash Compensation Incentive Plan of
the Company (the “2006 Compensation Plan”) with respect to any Shares deferred subsequent to the adoption of the 2006 Compensation Plan by the Company’s shareholders, or the Company’s 1997 Employee Stock Option Plan with respect
to any Shares deferred prior to the adoption of the 2006 Compensation Plan by the Company’s shareholders. Distribution shall be made to the Participant, or if the Participant has died to the Participant’s Beneficiary. The Company may
distribute the value of any fractional Deferred Stock Unit in cash, based on the Fair Market Value on the date any shares of Common Stock are distributed. 
 E. Death. If the Participant dies prior to the total distribution of his or her account then the vested balance that is undistributed at the time of the Participant’s death, notwithstanding any prior election by the Participant
for installment distributions, shall be distributed to the Participant’s Beneficiary, in a lump sum, within 90 days following the Participant’s death. 
 F. Specified Employee. If at the time of separation from service the Participant is considered a specified employee as defined in Section 409A then, notwithstanding the foregoing, the distribution of his or her account shall not
be made, or commence, until six months and one day after such separation from service, but installments shall thereafter be distributed as if the initial installment had been made on the date of separation. 
 G. Special 2008 Election. Notwithstanding the foregoing terms of the Plan, in accordance with the transition provisions of IRS Notice 2007-86, the Participants
who have previously made a proper election to defer Compensation for 2005, 2006, 2007 and 2008 may designate, in such manner as the HR director determines, prior to December 31, 2008, whether such Plan Year Deferrals shall be distributed in a
lump sum or in installments, and if in installments, the number of such installments. 
  

	7.	Amendments and Termination. 

 The Board of Directors may amend or
terminate the Plan at any time, which may include, without limitation, action to prohibit any future deferral under the Plan; provided that no such action shall decrease the value of the Participant’s account with respect to Deferral Elections
made prior to such termination or amendment and such amendment or termination shall be consistent with Section 409A.
