Re: Teradyne Offer of Employment

Dear Sanjay,

We are pleased to offer you the regular, full-time position of Vice President and Chief Financial Officer, reporting to myself, at our North Reading, MA headquarters. We expect your start date will be April 24, 2019 (“Start Date”).

Cash Compensation

You will be paid on a monthly basis at a rate of $41,667 per month. This represents an annualized salary of $500,000. You also will be eligible to participate in our Variable Compensation Plan at a 75% factor. The actual Variable Compensation payout will be determined after the end of the fiscal year by Teradyne’s Compensation Committee. For certain salary-dependent benefits programs such as life insurance and profit sharing, Teradyne will use your “model compensation” that equals your base salary plus your variable compensation at target, or $875,000. Your first salary review will be in January 2020. Also, we are pleased to offer you participation in Teradyne’s discretionary cash profit sharing plan, prorated based on the Start Date.

Equity Compensation

In addition to your cash compensation, you will be eligible to participate in our Executive Officer Equity Compensation Program. In connection with the commencement of your employment, Teradyne will grant you a new hire equity award in the amount of $1,400,000 as follows:

1. Restricted Stock Unit award consisting of the right to receive shares of Teradyne common stock equivalent in value to $560,000. The number of restricted stock unit shares will be determined by dividing $560,000 by the closing price of Teradyne common stock on the first trading day of the month following your Start Date (“Grant Date”). This Restricted Stock Unit award will vest in equal amounts annually over four (4) years, subject to the terms of the Company’s Restricted Stock Unit Agreement.

2. Performance-based Restricted Stock Unit awards consisting of the right to receive shares of Teradyne common stock equivalent in value to $700,000 at target. The target number of performance-based restricted stock unit shares will be determined by dividing $700,000 by the closing price of Teradyne common stock on the Grant Date. The final number of performance-based restricted stock unit shares earned will be determined by the Compensation Committee upon the completion of the performance periods of the awards (December 31 of the year prior to the three-year anniversary of the grant date). These Performance-based Restricted Stock Unit awards will vest in full on the third anniversary of the date of grant, subject to the terms of the Company’s Performance-based Restricted Stock Unit Agreement.

3. Non-qualified Stock Option award consisting of the right to purchase shares of Teradyne common stock equivalent in value to $140,000 at a strike price equal to the closing price of Teradyne common stock on the Grant Date. The number of stock options will be determined based on the fair market value of the options calculated as of the Grant Date. The stock options will vest in equal amounts annually over four (4) years and will expire seven years from the date of grant, subject to the terms of the Company’s Non-qualified Stock Option Agreement.

The equity awards set forth above are subject to approval of the Compensation Committee, will be made on the Grant Date and will be subject to the terms and conditions of the Company’s equity agreements and the terms of the 2006 Equity and Cash Compensation Incentive Plan.

Sign-on Compensation

Teradyne offers you sign-on compensation as follows:

1. A Restricted Stock Unit award consisting of the right to receive shares of Teradyne common stock equivalent in value to $1,100,000. The number of restricted stock unit shares will be determined by dividing $1,100,000 by the closing price of Teradyne common stock on the Grant Date. This Restricted Stock Unit award will vest in equal amounts annually over two (2) years, subject to the terms of the Company’s Restricted Stock Unit Agreement.

2. A one-time, sign-on cash bonus of $600,000 (“Sign-on Bonus”), subject to all required taxes and withholdings, to be paid in the amount of $300,000 one (1) month from your Start Date and $300,000 six (6) months from your Start Date. The Sign-on Bonus is an unvested wage advance upon receipt that you will earn 50% by remaining employed by Teradyne for one (1) month following your Start Date and 50% by remaining employed by Teradyne for six (6) months from your Start Date. If your employment with Teradyne terminates (voluntarily or for Cause) less than thirteen (13) full months after your Start Date, you agree to repay one hundred percent (100%) of the Sign-on Bonus.
