Note 1: You are not releasing any claims that You cannot release or waive by law, including but not limited to the right to file a charge with, or participate in an investigation conducted by, any appropriate federal, state or local government agency. Further, nothing in this Agreement should be construed to prohibit You from such filings or participation. You are, however, releasing and waiving Your right, and the right of anyone claiming on Your behalf, to any monetary recovery should any government agency (such as the Equal Employment Opportunity Commission (“EEOC”), National Labor Relations Board (“NLRB”), Occupational Safety and Health Administration (“OSHA”), Securities and Exchange Commission (“SEC”) or Department of Labor (“DOL”)) pursue any claims on Your behalf. Notwithstanding this Note 1, nothing contained in this Agreement shall impede Your ability to report possible federal securities violations to the SEC and other governmental agencies (i) without the Company’s approval and (ii) without having to forfeit or forego any resulting whistleblower awards.

b.    You shall reasonably cooperate with the Company and its Affiliates in any ongoing or future investigation or litigation as requested by the Company. The Company shall reimburse You for reasonable and necessary expenses associated with Your cooperation. This requirement does not limit Your right to file a charge with, or participate in, an investigation conducted by any appropriate federal, state or local government agency (such as the EEOC, NLRB, SEC, DOL or OSHA), nor does it require You to provide anything other than truthful information in good faith to the best of Your ability.

c.    You will not disparage in any way, or make negative comments of any sort, about the Company or its Affiliates, their employees, customers, or vendors, whether orally or in writing, and whether to a third party or to an employee of the Company or its Affiliates. The Company agrees to instruct its current executive officers (as listed in the annual report on Form 10-K to be filed with the SEC on or about February 26, 2020) to not disparage You in any way or make negative comments of any sort about You. This prohibition does not limit Your right to file a charge with, or participate in, an investigation conducted by any appropriate federal, state or local government agency (such as the EEOC, NLRB, SEC, DOL or OSHA), nor does it require You to provide anything other than truthful information in good faith to the best of Your ability.

d.    You agree that You will not, on Your own behalf or on behalf of any other person, file or initiate any civil complaint or suit against the Company or its Affiliates in any forum for any claims waived or released by this Agreement.

a.    You understand that You remain bound by the Confidentiality and Assignment of Invention Agreement and Restrictive Covenant Agreement signed by You on December 11, 2017, and any other confidentiality, non-competition or non-solicitation agreements You signed during Your employment with the Company, which remain in full force and effect pursuant to their terms.
