However, Employee is not required to provide the Company with such notice as set forth in Paragraph 6 or if the court order, judicial process, or regulatory authority prohibits Employee from doing so.

Employee understands that nothing in this Agreement shall in any way limit or prohibit Employee from engaging for a lawful purpose in any Protected Activity. For purposes of this Agreement, “Protected Activity” shall mean filing a charge or complaint, or otherwise communicating, cooperating, or participating with, any federal, state, local, or other governmental agency, including the Securities and Exchange Commission, the Equal Employment Opportunity Commission, and the National Labor Relations Board.

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 (a) 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 (b) 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.

Employee agrees to provide reasonable written notice to the Company in the event that a person or entity not a party hereto attempts to compel from Employee the production of this Agreement or the contents thereof, so that the Company may contest such disclosure at its discretion. Notwithstanding anything in this Agreement, this confidentiality provision and those in Paragraph 9 below do not prevent Employee from providing information in response to valid and enforceable subpoenas or otherwise required by law or regulation, from providing information necessary for preparation and filing of any income tax return, or from using this Agreement to enforce its terms.

This Agreement is governed by the laws of the State of Washington.
