Fraud or Misconduct – If the Company determines that you have engaged in fraudulent or willful misconduct, including violations of Company policies or applicable laws, or if your actions have caused significant financial or reputational harm to the Company, any incentive- based compensation that was granted or paid to you may be subject to recovery, forfeiture, or reimbursement.

The Company reserves the right to modify this clawback clause to ensure compliance with applicable laws and regulations.

Other Employment – You agree that during the period of your employment by Shimmick or its parent, subsidiary or other affiliated companies, you will not, without the Company's express written consent, engage in any employment or business activity, which is competitive with, or would otherwise conflict with, your employment by Shimmick or its parent or affiliated companies.

Confidentiality Obligation to Third Parties – You represent that your performance of your duties as an employee of Shimmick or its parent, subsidiary or other affiliated companies does not and will not breach any agreement or responsibility that you currently have to keep in confidence information acquired by you in trust prior to your employment by Shimmick or its parent, subsidiary or other affiliated companies. You will not disclose confidential or inside information that you possess or may obtain from your former employer such as source selection information, contractor bid or proposal information.

Other Post-Employment Obligations – In the event you leave the employ of Shimmick or its parent, subsidiary or other affiliated companies, you shall notify your new employer of your confidentiality and non- solicitation obligations under this Agreement and hereby consent to Company also providing such notification to any prospective employer.

Arbitration of Disputes – You and the Company knowingly agree to use a system of alternative dispute resolution that involves binding arbitration to resolve all disputes that may arise out of the employment context. Because of the mutual benefits (such as reduced expense and increased efficiency) which private binding arbitration can provide both you and the Company, both the Company and you agree that any claim, dispute, and/or controversy that either you or the Company (or its owners, directors, officers, managers, employees, agents, and parties affiliated with its employee benefit and health plans) may have against the other which would otherwise require or allow resort to any court or other governmental dispute resolution forum arising from, related to, or having any relationship or connection whatsoever with you seeking employment with, employment by, or other association with the Company, whether based on tort, contract, statutory, or equitable law, or otherwise, (with the sole exception of claims arising under the National Labor Relations Act which are brought before the National Labor Relations Board, claims for medical and disability benefits under the California Workers’ Compensation Act, and Employment Development Department claims) shall be submitted to and determined exclusively by binding arbitration under the Federal Arbitration Act, in conformity with the procedures of the California Arbitration Act (Cal. Code Civ. Proc. sec. 1280 et seq., including section 1283.05 and all of the Act’s other mandatory and permissive rights to discovery). Additionally, nothing herein shall prevent you from filing and pursuing administrative proceedings only before the California Department of Fair Employment and Housing, or the

U.S. Equal Opportunity Commission. Any dispute regarding the validity, scope or enforceability of this agreement, or concerning the arbitrability of a particular claim, shall be resolved by a court, not by the arbitrator.

At the beginning of any arbitration process under this agreement, you and the Company will need to select an arbitrator by mutual agreement. In addition to requirements imposed by law, any arbitrator herein shall be a retired California Superior Court Judge and shall be subject to disqualification on the same grounds as would apply to a judge of such court. To the extent applicable in civil actions in California courts, the following shall apply and be observed: all rules of pleading (including the right of demurrer), all rules of evidence, all rights to resolution of the dispute by means of motions for summary judgment, judgment on the pleadings, and judgment under Code of Civil Procedure section 631.8. Resolution of the dispute shall be based solely upon the law governing the claims and defenses pleaded, and the arbitrator may not invoke any basis (including but not limited to, notions of “just cause”) other than such controlling law. The arbitrator

shall have the immunity of a judicial officer from civil liability when acting in the capacity of an arbitrator, which immunity supplements any other existing immunity. Likewise, all communications during or in connection with the arbitration proceedings are privileged in accordance with Cal. Civil Code section 47(b). As reasonably required to allow full use and benefit of this agreement's modifications to the Act’s procedures, the arbitrator shall extend the times set by the Act for the giving of notices and setting of hearings. Awards shall include the arbitrator's written reasoned opinion.

Should any term or provision, or portion thereof, be declared void or unenforceable it shall be severed, and the remainder of this agreement shall be enforceable. The Company will pay the arbitrator’s fees and other costs relating to the arbitration forum and you and the Company will be responsible for their own costs and for their own attorneys’ fees should they choose to be represented by counsel, unless the arbitrator shifts one party’s costs and attorneys’ fees to the other party in accordance with applicable law.

YOU AND THE COMPANY UNDERSTAND BY AGREEING TO THIS BINDING ARBITRATION PROVISION, BOTH YOU AND THE COMPANY GIVE UP THEIR RIGHTS TO TRIAL BY JURY OF ANY CLAIM YOU OR COMPANY MAY HAVE AGAINST EACH OTHER ARISING OUT OF THE EMPLOYMENT RELATIONSHIP.

Governing Law – This Agreement shall be construed and enforced pursuant to the laws of the state of employment. Should any provision of this Agreement be declared illegal or unenforceable by any court of competent jurisdiction and cannot be modified to be enforceable, such provision shall become null and void, leaving the remainder of this Agreement in full force and effect.

Offer of Employment – The Offer Letter and this Addendum represent Shimmick’s complete offer of employment. Any other discussions that you may have had with anyone at Shimmick or any authorized agent of Shimmick are not part of the offer of employment unless they are described in this letter. If this letter does not correctly reflect your understanding of the terms of employment, please notify Shimmick as soon as possible.

At-Will Employment - Nothing in these terms and conditions is intended to change the at-will nature of your employment with Shimmick. At-will employment means that you or the company can terminate the employment relationship at any time with or without cause or notice.

I have read, understand, agree and accept the terms and conditions of the Offer Letter and this Addendum.
