Company; (b) the Separation Consideration represents full and complete payment and satisfaction of any and all payments or benefits to which Employee is or may become entitled to under the Offer Letter, the Severance Policy, or any other agreement or arrangement with or plan or policy of the Company (collectively, the “Company Arrangements”); (c) except as otherwise provided in this Agreement, Employee is not entitled to receive compensation, fringe benefits, separation benefits or any other employee benefits of any kind from the Company on or after the Separation Date; (d) Employee has reported all workplace injuries; (e) Employee has had the opportunity to provide the Company with written notice of any concerns regarding suspected ethical and compliance issues on the part of the Company or any other Releasee; (f) Employee does not have a pending claim against the Company or any Releasee, including, but not limited to, for sexual assault; sexual harassment; or unlawful workplace harassment or discrimination, failure to prevent an act of workplace harassment or discrimination, or an act of retaliation against a person for reporting or opposing harassment or discrimination; or any other pending claims that are released under this Agreement, whether or not filed in a court or government agency proceeding, in an alternative dispute resolution forum, or through the Company’s internal complaint process.

4.Expense Reimbursements.

11.Tax Consequences. The Company makes no representations with respect to the tax consequences of the payments and any other consideration provided to Employee or made on Employee’s behalf under the terms of this Agreement. Employee agrees and understands that Employee is responsible for payment, if any, of local, state, and/or federal taxes on the payments and any other consideration provided hereunder by the Company and any penalties or assessments thereon. Employee further agrees to indemnify and hold the Releasees harmless from any claims, demands, deficiencies, penalties, interest, assessments, executions, judgments, or recoveries by any government agency against the Company for any amounts claimed due on account of (a) Employee’s failure to pay or delayed payment of federal or state taxes, or (b) damages sustained by the Company by reason of any such claims, including attorneys’ fees and costs.

12.Protected Rights. Employee understands that nothing in this Agreement shall in any way limit or prohibit Employee from engaging in any Protected Activity. Protected Activity includes: (i) filing and/or pursuing a charge, complaint, or report with, or otherwise communicating, cooperating, or participating in any investigation or proceeding that may be conducted by any federal, state or local government agency or commission, including the Securities and Exchange Commission, the Equal Employment Opportunity Commission, the Occupational Safety and Health Administration, and the National Labor Relations Board (“Government Agencies”); and/or (ii) discussing or disclosing information about unlawful acts in the workplace, such as harassment or discrimination or any other conduct that Employee has reason to believe is unlawful. Notwithstanding the foregoing, Employee agrees to take all reasonable precautions to prevent any unauthorized use or disclosure of any Company trade secrets, proprietary information, or confidential information that does not involve unlawful acts in the workplace or the activity otherwise protected herein. Employee further understands that Protected Activity does not include the disclosure of any Company attorney-client privileged communications or attorney work product. In addition, pursuant to the Defend Trade Secrets Act of 2016, Employee is notified that an individual will not be held criminally or civilly liable under any federal or state trade secret law for the disclosure of a trade secret that (i) is made in confidence to a federal, state, or local government official (directly or indirectly) or to an attorney solely for the purpose of reporting or investigating a suspected violation of law, or (ii) is made in a complaint or other

document filed in a lawsuit or other proceeding, if (and only if) such filing is made under seal. In addition, an individual who files a lawsuit for retaliation by an employer for reporting a suspected violation of law may disclose the trade secret to the individual’s attorney and use the trade secret information in the court proceeding, if the individual files any document containing the trade secret under seal and does not disclose the trade secret, except pursuant to court order. Finally, nothing in this Agreement constitutes a waiver of any rights Employee may have under the Sarbanes-Oxley Act or Section 7 of the National Labor Relations Act (“NLRA”). For purposes of clarity, nothing in this Agreement shall be interpreted to impair or limit Employee’s participation in any legally protected activities, such as (i) forming, joining, or supporting labor unions, (ii) bargaining collectively through representatives of employees’ choosing, (iii) discussing wages, benefits, or terms and conditions of employment, and (iv) discussing, or raising complaints about, working conditions for the purpose of mutual aid or protection of Employee or the Company’s other current or former employees, to the extent such activities are protected by Section 7 of the NLRA.

13.Section 409A. The Company intends that all payments and benefits provided under this Agreement or otherwise are exempt from, or comply with, the requirements of Section 409A of the Code and any guidance promulgated thereunder (collectively, “Section 409A”) so that none of the payments or benefits will be subject to the additional tax imposed under Section 409A, and any ambiguities herein will be interpreted in accordance with this intent. No payment or benefits to be paid to Employee, if any, under this Agreement or otherwise, when considered together with any other severance payments or separation benefits that are considered deferred compensation under Section 409A (together, the “Deferred Payments”) will be paid or otherwise provided until Employee has a “separation from service” within the meaning of Section 409A. If, at the time of the Employee’s termination of employment, Employee is a “specified employee” within the meaning of Section 409A, then the payment of the Deferred Payments will be delayed to the extent necessary to avoid the imposition of the additional tax imposed under Section 409A, which generally means that the Employee will receive payment on the first payroll date that occurs on or after the date that is 6 months and 1 day following his or her termination of employment. Each payment, installment, and benefit payable under this Agreement is a separate payment for purposes of U.S. Treasury Regulation Section 1.409A-2(b)(2). In no event will the Company or any subsidiary of the Company reimburse any Employee for any taxes that may be imposed on him or her, including as a result of Section 409A.

This Agreement fully releases and extinguishes all of Employee’s rights and the Company’s obligations to provide any payments or benefits under any other Company Arrangements. This Agreement is entered into without reliance on any promise or representation, written or oral, other than those expressly contained herein, and supersedes

any other such promises, warranties, or representations. This Agreement may not be modified or amended except in a writing signed by Employee and a duly authorized representative of the Company. The Parties agrees that should any part of this Agreement, except the release of claims, be found to be void or unenforceable by a court or arbitrator, that determination will not affect the remainder of this Agreement, and a court or arbitrator shall have the power to interpret and reform any void or unenforceable provision so as to comply with legal requirements and the intent of the Parties.

16.Breach. Employee acknowledges and agrees that any material breach of this Agreement or the CIPCAA, shall entitle the Company to cease providing any of the consideration and benefits provided to Employee under this Agreement and to recover damages for such breach.
