2.    VALUABLE CONSIDERATION

2.1    Severance Package. Employer agrees to provide Employee with the following payments and benefits (“Severance Package”). Employee acknowledges and agrees that the Severance Package constitutes adequate legal consideration for the promises and representations made by her in the Agreement. Receipt of the Severance Package is contingent upon the following conditions: (i) Employee must continue to abide by the covenants regarding confidentiality, non-solicitation and non-disparagement described in Section 11 of the Retention Agreement, and (ii) application of the Recoupment Policy described in Section 6 of the Retention Agreement, the Golden Parachute Payments provision described in Section 7 of the Retention Agreement, and the provisions regarding compliance with Section 409A of the Internal Revenue Code described in Section 13 of the Retention Agreement. Subject to the foregoing, Employer will pay the Severance Payment on the sixtieth (60th) day after the Separation Date.

2.1.1.    Severance Payment. Employer agrees to pay Employee a total of $1,334,048, computed in accordance with Section 3(a) of the Retention Agreement, less all appropriate federal and state income and employment taxes (“Severance Payment”).

3.    GENERAL RELEASE AND WAIVER

3.1    In consideration of Employer’s promises made within this Agreement, Employee unconditionally, irrevocably and absolutely waives, releases and discharges Employer, and any parent and subsidiary corporations, divisions and affiliated corporations, partnerships or other affiliated entities of Employer, past and present, as well as the past and present employees, officers, directors, agents, successors and assigns of Employer (collectively, “Released Parties”), from all claims related in any way to the transactions or occurrences between them to date, to the fullest extent permitted by law, including, but not limited to, Employee’s employment with Employer, the termination of Employee’s employment with Employer, and all other losses, liabilities, claims, charges, demands and causes of action, known or unknown, suspected or unsuspected, arising directly or indirectly out of or in any way connected with Employee’s employment with Employer. This release is intended to have the broadest possible application and includes, but is not limited to, any tort, contract, common law, constitutional or other statutory claims, including, but not limited to claims involving intellectual property or innovations that Employee may have worked on or come up with during the period in which she was being compensated by any of the Released Parties, alleged violations of the Illinois Human Rights Act, the Illinois Minimum Wage Law, the Illinois Wage Payment and Collection Act, the Illinois One Day Rest in Seven Act, the Illinois Victims' Economic Security and Safety Act, the Illinois Personnel Record Review Act, the Illinois Worker Adjustment and Retraining Notification Act, the Illinois Right to Privacy in the Workplace Act, the Illinois Workers' Compensation Act and any other statute set forth in Chapter 820 or any other chapter of the Illinois Compiled Statutes that pertains or relates to, or otherwise touches upon, the employment relationship between Employer and Employee, Title VII of the Civil Rights Act of 1964, the Americans with Disabilities Act, the Age Discrimination in Employment Act, and all claims for attorneys’ fees, costs and expenses. Employee expressly waives Employee’s right to recovery of any type, including damages, in any administrative or court action, whether state or federal, and whether brought by Employee or on Employee’s behalf, related in any way to the matters released herein. However, this general release is not intended to bar any claims that, by statute, may not be waived, such as claims for any challenge to the validity of Employee’s release of claims under the Age Discrimination in Employment Act, as set forth in this Agreement. Further, nothing in this Section 3.1 shall release any of the Released Parties’ obligations, covenants, and agreements under this Agreement or Employee’s rights under applicable law, the Company’s Bylaws, any Company officer indemnity agreement to which Employee is a party or the Company’s director and officer liability policy to seek indemnity for acts committed, or omissions, within the course and scope of Employee’s employment duties.

3.2    Employee acknowledges that Employee may discover facts or law different from, or in addition to, the facts or law that Employee knows or believes to be true with respect to the claims released in this Agreement and agrees, nonetheless, that this Agreement and the release contained in it shall be and remain effective in all respects notwithstanding such different or additional facts or the discovery of them.

3.3    Employee declares and represents that Employee intends this Agreement to be complete and not subject to any claim of mistake, and that the release herein expresses a full and complete release and Employee intends the release herein to be final and complete.

3.4    Employee represents that, as of the date of this Agreement, she has not filed any lawsuits, charges, complaints, petitions, claims or other accusatory pleadings against Employer or any of the other Released Parties in any court or with any governmental agency.

3.5    Employee acknowledges and agrees that the general release and waiver clause in this Agreement is an essential and material term of the Agreement, and that without such clause, no agreement would have been reached by the Parties.

4.    ACKNOWLEDGEMENTS BY EMPLOYEE

4.1    Employee acknowledges that she is subject to, and will continue to abide by, all surviving provisions of the Retention Agreement, including, without limitation, the covenants regarding confidentiality, non-solicitation and non-disparagement set forth in Section 11 of the Retention Agreement (the “Covenants”), all of which are incorporated herein by reference as if set forth herein in their entirety.

5.    NON-DISPARAGEMENT. Employee confirms and agrees that she will not make any oral or written statements to any third party about any of the Released Parties that are either intended or reasonably likely either to disparage any of the Released Parties. Employee acknowledges and agrees that the non-disparagement clause in this Agreement is an essential and material term of the Agreement, and that without such clause, no agreement would have been reached by the Parties. Additionally, if Employee is compelled by the legal process to provide statements, information, or testimony regarding her employment with any of the Released Parties, she will do so in a truthful manner, and doing so is not a breach of the terms of this Agreement.

The Severance Package shall become due and payable in accordance with Section 2 above after the Effective Date.

6.3    Preserved Rights of Employee. This Agreement does not waive or release any rights or claims that Employee may have under the Age Discrimination in Employment Act that arise after the execution of this Agreement. In addition, this Agreement does not prohibit Employee from challenging the validity of this Agreement’s waiver and release of claims under the Age Discrimination in Employment Act.

7.    CONFIDENTIALITY/RETURN OF COMPANY PROPERTY

7.1    Employee represents and warrants that as of the Separation Date, she will have returned all property belonging to Employer. Such property includes, but is not limited to, keys, passwords, access cards, credit or phone cards, any computer hardware or software, any products relating to Employer or its competition, any design work, product engineering, test results, customer information, pricing and cost information, financial data or information, any vendor samples or information, management materials, including all correspondence, manuals, letters, notes, notebooks, data report programs, plan proposals, and other confidential, proprietary and/or trade secret information, regardless of whether the information is in written, printed, electronic, or other form and regardless of whether it was written or compiled by Employee or other persons, as well as any and all other property that comprises property owned by Employer. Employee agrees that she will not retain any originals or copies of any Employer property, whether prepared or created by Employee or otherwise coming into Employee’s possession or control in the course of her employment with Employer. Employee agrees to keep the terms of the Agreement confidential between her and Employer, except that she may tell her immediate family and attorney or accountant, if any, as needed, but in no event should she discuss the Agreement or its terms with any current or prospective employee of Employer. Notwithstanding the foregoing, Employee understands that pursuant to the Defend Trade Secrets Act of 2016, Employee shall 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 (i) in confidence to a federal, state, or local government official, either directly or indirectly, or to

an attorney; and (ii) 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 such filing is made under seal. In addition, nothing in this Agreement shall be interpreted or applied to prohibit Employee from making any good faith report to any governmental agency or other governmental entity concerning any acts or omissions that Employee may believe to constitute a possible violation of federal or state law or making other disclosures that are protected under the whistleblower provisions of applicable federal or state law or regulation. Further, this Agreement does not limit Employee’s ability to communicate with any government agency or otherwise participate in any investigation or proceeding that may be conducted by any government agency, including providing documents or other information, without notice to Employer. If Employee files any charge or complaint with a government agency and if the government agency pursues any claim on Employee’s behalf, or if any third party pursues any claim on Employee’s behalf, Employee waives any right to monetary or other individualized relief (either individually or as part of any collective or class action); provided that nothing in this Agreement limits any right Employee may have to receive a whistleblower award or bounty for information provided to the Securities and Exchange Commission.
