Change of Control Severance Agreement dated July 20, 2022 by and between Shai Shahar and FormFactor, Inc

This Change of Control Severance Agreement (the “Agreement”) is made and entered into effective as of July 20, 2022 (the “Effective Date”), by and between the undersigned employee (the “Employee”) and FormFactor, Inc., a Delaware corporation (the “Company”).

A.    The Company considers it essential to the best interests of its shareholders to foster the continuous employment of key management personnel.

B.    The Board of Directors of the Company (the “Board”) recognizes that, as is the case with many publicly held corporations, the possibility of a Change in Control (as defined below) exists and that such possibility, and the uncertainty and questions which it may raise among management, could result in the departure or distraction of management personnel to the detriment of the Company and its shareholders.

C.    The Board has determined that appropriate steps should be taken to reinforce and encourage the continued attention and dedication of members of the Company’s management, including the Employee, to their assigned duties without distraction in light of the possibility of a Change in Control.

NOW THEREFORE, in consideration of the premises and the mutual covenants herein contained, the Company and the Employee hereby agree as follows.

4.Change of Control and Severance Benefits; Non-solicitation.

(a)Involuntary Termination Following Change of Control.

(iv)Forfeiture upon Breach of Covenants.

(a)Other Termination in Connection with a Change of Control. If the Employee’s employment with the Company terminates other than as a result of an Involuntary Termination at any time within twelve (12) months after a Change of Control, then the Employee shall not be entitled to receive the Severance Benefits, but may be eligible for those benefits (if any) as may then be established under the Company’s or a successor company’s then existing severance and benefits plans and policies.

(b)Termination Apart from a Change of Control. If the Employee’s employment with the Company terminates for any or no reason other than within twelve (12) months following a Change of Control, then the Employee shall not be entitled to receive the Severance Benefits, but may be eligible for those benefits (if any) as may then be established under the Company’s then existing severance and benefits plans and policies at the time of such termination.

5.Limitation on Benefits.

(b)Notwithstanding anything contained in this Agreement to the contrary, to the extent that the payments and benefits provided under this Agreement and benefits provided to, or for the benefit of, the Employee under any other employer plan or agreement (such payments or benefits are collectively referred to as the “Benefits”) would constitute “excess parachute payments” (as such term is defined under Section 280G of the Code or any successor provisions, and the regulations promulgated thereunder) that would be subject to the excise tax (the “Excise Tax”) imposed under Section 4999 of the Internal Revenue Code of 1986, as amended (the “Code”), the Benefits shall be reduced (but not below zero) if and to the extent that a reduction in the Benefits would result in Employee retaining a larger amount, on an after-tax basis (taking into account federal, state and local income taxes and the Excise Tax), than if Employee received all of the Benefits (such reduced amount is hereinafter referred to as the “Limited Benefit Amount”). The Company shall reduce or eliminate the Benefits, by first reducing or eliminating those payments or benefits which are not payable in cash and then by reducing or eliminating cash payments, in each case in reverse order beginning with payments or benefits which are to be paid the farthest in time from the “Determination” (as hereinafter defined). Any such reduction shall be made in a manner consistent with the requirements of Section 409A of the Code.

(c)A determination as to whether the Benefits shall be reduced to the Limited Benefit Amount pursuant to this Agreement and the amount of such Limited Benefit Amount

shall be made by the Company’s independent public accountants or another certified public accounting firm or valuation firm designated by the Company (the “Accounting Firm”) at the Company’s expense. The Accounting Firm shall provide its determination (the “Determination”), together with detailed supporting calculations and documentation to the Company and Employee within thirty (30) days of the date of termination of Employee’s employment.

6.Successors.

For all purposes under this Agreement, the term “Company” shall include any successor to the Company’s business and/or assets.

(g)Employee’s Successors. Without the written consent of the Company, Employee shall not assign or transfer this Agreement or any right or obligation under this Agreement to any other person or entity. Notwithstanding the foregoing, the terms of this Agreement and all rights of Employee hereunder shall inure to the benefit of, and be enforceable by, Employee’s personal or legal representatives, executors, administrators, successors, heirs, distributees, devisees and legatees.

EMPLOYEE UNDERSTANDS THAT SUBMITTING ANY CLAIMS ARISING OUT OF, RELATING TO, OR IN CONNECTION WITH THIS AGREEMENT, OR THE INTERPRETATION, VALIDITY, CONSTRUCTION, PERFORMANCE, BREACH OR TERMINATION THEREOF TO BINDING ARBITRATION, CONSTITUTES A WAIVER OF EMPLOYEE’S RIGHT TO A JURY TRIAL AND RELATES TO THE RESOLUTION OF ALL DISPUTES RELATING TO ALL ASPECTS OF THE EMPLOYER/EMPLOYEE RELATIONSHIP, INCLUDING BUT NOT LIMITED TO, THE FOLLOWING CLAIMS:

(f)Section 409A. It is intended, and this Agreement will be so construed, that any amounts payable under this Agreement shall either be exempt from or comply with the provisions of Section 409A of the Code and the treasury regulations relating thereto so as not to subject the Employee to the payment of interest and/or any tax penalty that may be imposed under Section 409A of the Code. The Company may take any action (including with retroactive effect) that it determines necessary or appropriate to exempt any payment under this Agreement from the application of Section 409A of the Code or to cause any payment to comply with the requirements of Section 409A of the Code. Employee acknowledges and agrees that the Company has made no representation to Employee as to the tax treatment of the compensation and benefits provided pursuant to this Agreement and that Employee is solely responsible for all taxes due with respect to such compensation and benefits. In addition, to the extent (i) any payments to which Employee becomes entitled under this Agreement in connection with Employee’s termination of employment with the Company constitutes deferred compensation subject to Section 409A of the Code and (ii) Employee is deemed at the time of such termination of employment to be a “specified” employee under Section 409A of the Code, then to the extent required to avoid adverse tax treatment under Section 409A of the Code to Employee, such payment or payments shall not be made or commence until the date which is more than six (6) months after the Employee’s Separation from Service or, if earlier, the date of death of the Employee. If the condition of providing a Release by the Employee could cause the payment of any amount or provision of any Benefit subject to such release to be paid or provided in either of two taxable years of the Employee, then to the extent required to avoid adverse tax treatment to Employee under Section 409A of the Code, such amount or benefit shall be paid or provided in the later such taxable year, as necessary to comply with Section 409A of the Code. Neither the Company nor any of its affiliates shall be liable to Employee for any tax, penalty or interest imposed under or with respect to Section 409A of the Code or for reporting in good faith any payment made under this Agreement as an amount includible in gross income under Section 409A of the Code. Neither the Company nor any of its affiliates are hereby providing Employee with any tax advice with respect to Section 409A of the Code or otherwise and are not hereby making any guarantees or other assurances of any kind to Employee with respect to the tax consequences or treatment of any amounts paid or payable under this Agreement.

(g)No Duty to Mitigate. The Employee shall not be required to mitigate the amount of any payment contemplated by this Agreement, nor shall any such payment be reduced by any earnings that the Employee may receive from any other source.

(h)Waiver. No provision of this Agreement may be modified, waived or discharged unless the modification, waiver or discharge is agreed to in writing and signed by the Employee and by an authorized officer of the Company other than the Employee. No waiver by either party of any breach of, or of compliance with, any condition or provision of this Agreement by the other party shall be considered a waiver of any other condition or provision or of the same condition or provision at another time.

(i)Integration. This Agreement represents the entire agreement and understanding between the parties as to the subject matter herein and supersedes all prior or contemporaneous agreements, whether written or oral.

(j)Choice of Law. The validity, interpretation, construction and performance of this Agreement shall be governed by the internal substantive laws, but not the conflicts of law rules, of the State of California.

(k)Severability. The invalidity or unenforceability of any provision or provisions of this Agreement shall not affect the validity or enforceability of any other provision hereof, which shall remain in full force and effect.

(l)Withholding Taxes. All payments made pursuant to this Agreement shall be subject to applicable withholding or other tax obligations of the Company and the Company may withhold from any payments due to employee under this Agreement or otherwise any tax withholding required by applicable law.

(m)Counterparts. This Agreement may be executed in counterparts, each of which shall be deemed an original, but all of which together will constitute one and the same instrument.
