5.CONFIDENTIAL INFORMATION
Employee agrees that he is bound by the terms of the Confidential Information policy in the Company’s Code of Conduct, which Employee signed on January 23, 2023, and which is incorporated by reference herein.
6.MUTUAL NON-DISPARAGEMENT
Pursuant to the Colorado POWR Act, Employee and the Company agree not to disparage or defame the other. Such restriction does not prohibit Employee from disclosing the underlying facts of any alleged discriminatory or unfair employment practice, including the existence and terms of a settlement agreement, to Employee’s immediate family members, religious advisor, medical or mental health provider, mental or behavioral health therapeutic support group, legal counsel, financial advisor, or tax preparer. Such restriction does not prohibit Employee from disclosing the underlying facts of any alleged discriminatory or unfair employment practice to any government agency, including the existence and terms of a settlement agreement, or in response to a subpoena without first notifying the employer. In relation to the Company, the Company will not authorize or permit any disparaging or defamatory statements about Employee to be made on behalf of the Company. However, the Company cannot be liable for unauthorized comments by non-executive and non-board member employees.
The Parties acknowledge that disclosure of the underlying facts of any alleged discriminatory or unfair employment practice, does not constitute disparagement of the Company or others involved. The Company may not seek to enforce this provision or seek damages if the Company has breached this term first and disparaged Employee in violation of this section.




6.NO ADMISSION OF LIABILITY
This Agreement is not, and shall not be construed as, an admission of any wrongdoing, liability, or violation of any law or regulation by either Party. Both Parties expressly deny any such wrongdoing or liability.
7.ENTIRE AGREEMENT; AMENDMENTS
This Agreement constitutes the entire agreement between the Parties with respect to the subject matter hereof and supersedes all prior agreements, representations, and understandings, whether written or oral, relating to the Employee's separation from employment. This Agreement may not be modified or amended except by a written instrument signed by both Parties.

8.GOVERNING LAW AND DISPUTE RESOLUTION
This Agreement shall be governed by and construed in accordance with the laws of the State of Colorado, without regard to its conflict of laws principles. Any dispute arising out of or relating to this Agreement shall be resolved in state or federal court in Colorado.

9.SEVERABILITY

If any provision of this Agreement is held to be invalid or unenforceable, such provision shall be modified to the minimum extent necessary to make it enforceable, and the remaining provisions shall remain in full force and effect.

10.KNOWING AND VOLUNTARY EXECUTION
