Notwithstanding the foregoing, Employee recognizes that, in connection with the provision of information to any governmental entity, Employee must inform such governmental entity that the information Employee is providing is confidential. Despite the foregoing, Employee is not permitted to reveal to any third party, including any governmental entity, information Employee came to learn during Employee’s service to the Company that is protected from disclosure by any applicable privilege, including but not limited to the attorney-client privilege or attorney work product doctrine. The Company does not waive any applicable privileges or the right to continue to protect its privileged attorney- client information, attorney work product, and other privileged information. In addition, Employee agrees to waive Employee’s right to recover monetary damages in connection with any charge, complaint or lawsuit pertaining to the Released Matters filed by Employee or anyone else on Employee’s behalf (whether involving a governmental entity or not); provided that Employee is not agreeing to waive, and this Release shall not be read as requiring Employee to waive, any right Employee may have to receive an award for information provided to any governmental entity.

Company will reimburse Employee for reasonable out-of-pocket expenses Employee incurs in extending such cooperation, so long as Employee provides advance written notice of Employee’s request for reimbursement and provides satisfactory documentation of the expenses. Nothing in this section is intended to, and shall not, restrict or limit Employee from exercising Employee’s protected rights in Section 3 hereof or restrict or limit Employee from providing information in response to a subpoena, other legal process or valid governmental inquiry.

Nothing in this section is intended to, and shall not, restrict or limit Employee from exercising Employee’s protected rights under Section 3 hereof or restrict or limit Employee from providing information in response to a subpoena, other legal process or to a governmental or regulatory body or in the event of litigation between Employee and the Company or its affiliates, or prohibit Employee from making statements or engaging in any other activities or conduct protected by the National Labor Relations Act.
