precautions to prevent any unauthorized use or disclosure of any information that may constitute Company confidential information (as defined in the Confidentiality Agreement or any other agreement between you and the Company or any parent, subsidiary or other affiliate of the Company relating to the protection of confidential information) in a manner not protected by applicable law (each, a “Confidential Information Agreement”) to any parties other than the Governmental Entities. You further understand that Protected Activity does not include disclosure of any Company attorney-client privileged communications or attorney work product. Any language in the Confidentiality Agreement or any Confidential Information Agreement that conflicts with, or is contrary to, this paragraph is superseded by this Agreement. You understand and acknowledge that pursuant to the Defend Trade Secrets Act of 2016 (a) 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 is made (i) in confidence to a Federal, state, or local government official or to an attorney solely for the purpose of reporting or investigating a suspected violation of law, or (ii) in a complaint or other document filed in a lawsuit or other proceeding, if such filing is made under seal and (b) 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 attorney of the individual 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.

Miscellaneous. This Agreement, together with the Confidentiality Agreement, your CIC Agreement dated on or about the date hereof, and 2021 Equity Incentive Plan and award agreements governing the equity awards granted to you by the Company, constitute the entire agreement between you and the Company regarding the material terms and conditions of your employment, and they supersede and replace all prior representations or agreements between you and the Company. This Agreement will be governed by the laws of the State of North Carolina but without regard to the conflicts of law provision. This Agreement may be modified only by a written agreement signed by a duly authorized officer of the Company (other than yourself) and you.
