(b)

Vesting and Lapse of Restrictions. Subject to the terms of this Agreement, the PSUs covered by this Award shall vest and all Restrictions thereon shall lapse in accordance with the schedule set forth in the Notice of Award, provided in each case that Participant remains continuously as an employee of Company or a Subsidiary from the Award Date through the particular scheduled vesting date therefor (except only as may otherwise be expressly set forth in (i) any employment, severance or change in control agreement of the Company or a Subsidiary with Participant, or (ii) Section 3(g) below related to the Retirement or death of the Participant). For purposes of this Agreement, “Restrictions” shall mean the exposure to forfeiture set forth in this Award.

(c)

Acceleration of Vesting. Notwithstanding any other provision of this Award, with regard to any performance-based Award, in the event of a Change in Control event, the performance conditions will be deemed to have been achieved at the target level and the Participant will be deemed to have earned the target number of PSUs that were subject to the Award.

(d)

Tax Withholding; Issuance of Uncertificated Shares for Participants Domiciled Outside the U.S. For Participants domiciled outside of the United States, the provisions set forth herein related to U.S. federal and/or state tax withholding do not apply. Shares shall be delivered to such Participant or his or her legal representative at the time the vesting requirements as provided in this Award shall have been satisfied. Participants domiciled outside the U.S. are advised to consult with a local tax advisor regarding the tax ramifications of the Award in their country of residence and assure compliance with such tax obligations.

(e)

Tax Withholding for Participants Domiciled in U.S. Withholding Requirements. By accepting this Award, Participant agrees to make appropriate arrangements with the Company for the satisfaction, as of the applicable withholding date, of all applicable federal, state and local tax withholding requirements, including in connection with the vesting and settlement of this Award. No Shares will be issued until satisfaction of such applicable tax withholding has been received by the Company. Prior to the delivery of any Shares pursuant to this Award, the Company will have the power and the right to deduct or withhold an amount sufficient to satisfy federal, state, local, foreign or other taxes (including the Participant’s FICA obligation) required to be withheld with respect to the vesting or settlement of this Award.

(f)

Withholding Arrangements. The Company, pursuant to such procedures as it will specify from time to time, will permit Participant to satisfy such tax withholding obligation, in each case as of the applicable tax withholding date, by (without limitation and in such combinations as the Participant may elect):

(i) paying cash or by personal check, certified check or bank check or wire transfer of immediately available funds; or

(ii) electing to have the Company withhold otherwise deliverable Shares having a Fair Market Value equal to the minimum statutory amount required to be withheld.

The Fair Market Value of the Shares to be withheld or delivered will be determined as of the date that the taxes are required to be withheld. Participant may elect to make prior arrangements with the Stock Service to sell Shares as of the vesting date and apply the appropriate amount of the proceeds thereof to the applicable tax withholding amount and remit any balance of the proceeds to Participant, provided that if Participant elects to have any Shares sold by the Stock Service or otherwise, any such proposed sale of Shares shall be in compliance with and satisfy all requirements and conditions under the Onto Innovation Inc. Insider Trading Compliance Program.

(g)

Retirement; Death.

(a)

Subject to the terms of this Agreement, in the event of the Retirement of the Participant, the PSUs shall vest based on the actual performance results for performance-based Awards. For clarity, in the event of the Participant’s Retirement, there will be no acceleration of an Award’s vesting schedule or forfeiture of unvested Awards.

(b)

Subject to the terms of this Agreement, in the event of the death of the Participant while employed by Company, unvested PSUs shall become immediately vested in accordance with the following calculation:

•

The target number of PSUs multiplied by the number of days worked since the grant date divided by the total number of days in the full vesting term.

In the event of Retirement or death, any PSUs under this Award that do not vest under this Section 3(g) will be forfeited.

Company Share Issuance Prerequisites. Company shall not be required to issue or deliver any Shares prior to the fulfillment of all of the following conditions:

(a)

the admission of the Shares to listing on all stock exchanges on which such Common Stock is then listed;

(d)

the lapse of any such reasonable period of time following the date the Restrictions lapse as the Company may from time to time establish for reasons of administrative convenience.

Performance Stock Units Not Transferable.

Rights as Stockholder. Until Participant has satisfied all requirements for vesting and the satisfaction of all conditions set forth in this Agreement and Shares have been issued to Participant, Participant shall not be deemed to be a shareholder or to have any of the rights of a shareholder with respect to any such Shares.

Not a Contract of Employment. Nothing in this Agreement or in the Plan shall confer upon Participant any right to continue to serve as an employee or other Service Provider of Company or any of its Subsidiaries.

13.

Section 409A.

(a)

This Award is intended to constitute a “short-term deferral” for purposes of Section 409A of the Internal Revenue Code of 1986, as amended (“Code”) and the rules and regulations promulgated thereunder and is intended to comply with the requirements of Section 409A of the Code so as not to be subject to taxes, interest or penalties under Section 409A of the Code. This Agreement shall be interpreted and administered to give effect to such intention and understanding.

(b)

Notwithstanding anything in this Agreement to the contrary, any payment or issuance of Shares to be made to the Participant under this Award in connection with Participant’s separation from service shall not be made until the date six months and one day after the date of the Participant’s separation from service to the extent necessary to comply with Section 409A(a)(B)(i) of the Code and applicable Treasury regulations thereunder, after giving effect to the extent applicable to the short-term deferral exemption under Treasury Regulation §1.409A-1(b)(4) and the severance pay exemption under Treasury Regulation §1.409A-1(b)(9)(iii). Following any such six-month and one-day delay, all such delayed payments will be paid in a single lump sum on the date six months and one day after the Participant’s separation from service. For the purposes of this Agreement, “separation of service” means a separation from service as defined in Section 409A of the Code determined using the default provisions set forth in Treasury Regulation §1.409A-1(h) or any successor regulation thereto. Each and every payment or issuance of Shares made pursuant to this Award shall be deemed a separate payment or issuance and not a series of payments or issuances.

(c)

If any provision of this Award would, in the reasonable, good faith judgment of the Committee, result or likely result in the imposition on the Participant, beneficiary or any other person claiming by or through the Participant, of any additional tax, accelerated taxation, interest or penalties under Section 409A of the Code, the Committee may, in its sole discretion, modify the terms of this Award or take any other such action, without the consent of the Participant or any spouse, beneficiary or any other person claiming by or through the Participant, in the manner that the Committee may reasonably and in good faith determine to be necessary or advisable to avoid the imposition of such additional tax, accelerated taxation, interest or penalties or otherwise comply with Sections 409A of the Code. However, nothing in this Agreement is intended to or shall create any obligation or liability on the part of the Company or the Committee or its members to modify the Agreement, the Award or any PSUs or other rights granted hereunder nor guarantee that the Participant will not be subject to additional taxes, accelerated taxation, interest or penalties under Section 409A of the Code.
