Separation of Executive Vice President, Operations

On February 6, 2023, Inogen, Inc. (the "Company") and Bart Sanford, Executive Vice President, Operations of the Company, mutually determined that Mr. Sanford would separate from the Company on or before March 1, 2023.

In connection with Mr. Sanford's separation as Executive Vice President, Operations, Mr. Sanford and the Company entered into a transition agreement and release, whereby Mr. Sanford agreed to provide transition services to the Company in his current role until, at the latest, March 1, 2023.

The transition agreement provides that during the period Mr. Sanford provides these transition services, he will continue to receive his current base salary, receive employment benefits pursuant to the Company's benefit plans as in effect, and vest in his Company equity awards according to their terms.

The transition agreement also provides that subject to (i) Mr. Sanford's execution of the transition agreement and his timely execution of the supplemental release agreement attached to the transition agreement following the termination of his employment with the Company, (ii) both agreements going into effect and (iii) his fulfillment of all of the terms and conditions of both agreements, the Company will (a) provide for the continuation of payments of his base salary for 12 months from the effective date of his separation and (b) pay for a portion of the premium payments for COBRA coverage equal to the Company-paid portion for such benefits as of immediately before the date his employment terminates for a period of up to 18 months (or taxable monthly payments for the equivalent period in the event the Company determines that the COBRA subsidy could violate applicable law).

The summary of Mr. Sanford's transition agreement set forth above does not purport to be complete and is qualified in its entirety by reference to the full text of the transition agreement, which is attached to this Current Report on Form 8-K as Exhibit 10.1 and incorporated by reference herein.

## Exhibit 10.1

**Exhibit 10.1**

**TRANSITION AGREEMENT AND RELEASE**

This Transition Agreement and Release ("**Agreement**") is made by and between Bart Sanford ("**Employee**") and Inogen, Inc. (the "**Company**") (collectively referred to as the "**Parties**" or individually referred to as a "**Party**").

WHEREAS, Employee has been employed at-will by the Company pursuant to the terms and conditions of initial offer letter and agreements completed on his first day of employment on September 17, 2018 (the "**Employment Agreement**");

WHEREAS, Employee signed an At-Will Employment, Confidential Information, Invention Assignment, and Arbitration Agreement with the Company dated August 17, 2018 (the "**Confidentiality Agreement**");

WHEREAS, Employee previously was granted awards of some or all of stock options, restricted stock, restricted stock units, performance restricted stock, and performance stock units in each case, that are outstanding as of the date hereof (each, an "**Equity Award**") subject to the terms and conditions of the applicable Company equity plan under which the Equity Award was granted and an award agreement memorializing the Equity Award (the plan and award agreement together, the "**Stock Agreements**");

WHEREAS, the Parties have determined that Employee's employment with the Company will end no later than March 1, 2023 (Employee's actual last day of employment, whether March 1, 2023, or earlier, is referred to herein as the "**Separation Date**"); and

WHEREAS, the Parties wish to resolve any and all disputes, claims, complaints, grievances, charges, actions, petitions, and demands that the Employee may have against the Company and any of the Releasees (as defined below), including, but not limited to, any and all claims arising out of or in any way related to Employee's employment with or separation from the Company;

NOW, THEREFORE, in consideration of the mutual promises made herein, the Company and Employee hereby agree as follows:

**COVENANTS**

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;1.<u>Consideration</u>. The Parties acknowledge and agree that the following consideration exceeds, is in lieu of, and fully replaces any severance under Section 8 of the Employment Agreement:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;a.<u>Transition Opportunity.</u> In consideration of Employee's execution of this Agreement and Employee's fulfillment of all of its terms and conditions, and subject to Section 3 below, Employee will have the opportunity to continue employment with the Company on a transitional basis from the Effective Date until, at the latest, March 1, 2023 (such period, the "**Transition Period**" and such opportunity, the "**Transition Opportunity**"). During the Transition Period, Employee will provide transitional assistance to the Company, including by assisting the Company as set out below (the "**Transition Duties**"). During the Transition Period, Employee will report to Nabil Shabshab and perform his Transition Duties at the direction of Nabil Shabshab. During the Transition Period, Employee shall continue to receive Employee's base salary as in effect immediately prior to the Effective Date hereof at the rate of $380,000 per year, less all applicable withholdings (the "**Base Salary**"). If Employee's employment with the Company ends prior to the Separation Date, then the Company shall immediately terminate the Transition Period salary payments.

------

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;<u>i. Transition Duties/Employment Prior to Separation Date</u>. Prior to the Separation Date, Employee will dedicate himself to the successful transition of his duties in his position as appropriate and provide access and training to those taking on these duties in the future. Employee will demonstrate a consistently constructive approach to the work, transition activities of the team, and interactions with his colleagues. He will not disparage the organization, other Company employees or any other related external parties. He will complete work tasks as directed to cover these responsibilities. Transition activities should include, but are not limited to: <br>

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•Complete a transition plan by February 13, 2023

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•Be available on call for consultation until March 1, 2023

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;b.<u>Severance Benefits</u>. If and only if (x) Employee executes this Agreement and the Supplemental Release attached hereto as <u>Exhibit A</u>, (y) both agreements become effective and irrevocable, and (z) Employee fulfills all of the terms and conditions of this Agreement and the Supplemental Release, including, without limitation, complying with the covenants contained herein and complies with the Confidentiality Agreement, then, following the Separation Date, and subject to Section 2 below, Employee will be entitled to the following (collectively, the "**Severance Benefits**"):

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;i.<u>Continuation of Payment</u>. The Company agrees to pay the Base Salary for twelve (12) months (the "**Severance Term**") (26 pay periods at the gross amount of $14,615.38 each), less all applicable taxes and payable in accordance with the Company's regular payroll practices, it being agreed that each installment of Base Salary payable hereunder shall be deemed to be a separate payment for purposes of Section 409A of the Code;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;ii.<u>COBRA Reimbursement</u>. The Company shall pay the premium payments for COBRA coverage in an amount equal to the Company-paid portion for such benefits as of immediately prior to the Separation Date for a period of up to the first eighteen (18) full calendar months following the Separation Date, provided Employee timely elects and pays the employee's portion for continuation coverage pursuant to the Consolidated Omnibus Budget Reconciliation Act of 1985, as amended ("**COBRA**"), within the time period prescribed pursuant to COBRA. Notwithstanding the preceding, if the Company determines in its sole discretion that it cannot provide COBRA reimbursement benefits without potentially violating applicable law (including, without limitation, Section 2716 of the Public Health Service Act), the Company will instead provide the Employee a taxable payment in an amount equal to the Company-paid portion of the monthly COBRA premium to continue the Employee's group health coverage in effect on the date of termination of employment (which amount will be based on the premium for the first month of COBRA coverage), which payments will be made regardless of whether the Employee elects COBRA continuation coverage and will commence in the month following the month of the Separation Date and continue for the period of months indicated in this paragraph.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;c.<u>General</u>. Employee acknowledges that without this Agreement, Employee is otherwise not entitled to the consideration listed in this Section 1. Employee further acknowledges and agrees that Employee's separation from the Company does not entitle Employee to any severance or other post-employment benefits beyond the consideration set forth herein (including, without limitation, any such severance or post-employment benefits described in the Employment Agreement). Employee acknowledges that the Employment Agreement is fully replaced by and superseded by this Agreement, and therefore Employee waives any rights to severance or other post-employment benefits under the Employment Agreement.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;2.<u>Supplemental Release</u>. Following the Separation Date, in exchange for Employee's execution and non-revocation of a Supplemental Release Agreement in the form attached hereto as <u>Exhibit A</u> (the

------

"**Supplemental Release**"), Employee will receive the severance benefits set forth in Section 1.b above. (provided, however, that the Company may modify the Supplemental Release pursuant to or otherwise as may be required by applicable law). The Parties agree that changes to the Supplemental Release, whether material or immaterial, do not restart the running of any consideration period specified in the Supplemental Release.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;3.<u>Resignation</u>. Effective as of the Separation Date, Employee hereby resigns from all positions and offices currently held as an officer or employee, and if applicable, a director of the Company and all of its subsidiaries. Employee acknowledges that his resignation is not because of any disagreement with the Company on any matter relating to the Company's operations, policies or practices. Employee also agrees to execute any necessary documents or other forms necessary to effectuate or document his resignation as a matter of local, state, federal, or international law. Effective as of the Separation Date, Employee further understands and agrees that he will no longer serve in any positions with the Company or any subsidiary or affiliate of the Company, and hereby resigns from any and all such positions effective as of the end of the Transition Period.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;4.<u>At-Will Employment</u>. Employee acknowledges that unless terminated sooner, Employee's employment with the Company will terminate on March 1, 2023. Employee acknowledges and agrees that nothing in this Agreement is intended to alter the at-will nature of Employee's employment with the Company. Accordingly, Employee's employment with the Company may be terminated at any time, with or without Cause or for any or no reason, at Employee's option or at the option of the Company, with or without notice, whether on or before March 1, 2023.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;5.<u>Benefits; Equity Awards</u>. Employee's health insurance benefits shall cease no later than the last day of the month in which the Separation Date occurs, subject to Employee's right to continue Employee's health insurance under COBRA. Employee's participation in all benefits and incidents of employment, including, but not limited to, vesting in Equity Awards, and the accrual of bonuses and paid time off, will cease as of the Separation Date. Employee acknowledges that as of the Separation Date, (a) the then-unvested portion of the Equity Awards will cease vesting and be immediately forfeited pursuant to the Stock Agreements and (b) the then-vested, outstanding, and exercisable stock options that are Equity Awards shall remain exercisable for a limited period of time in accordance with the applicable Stock Agreements.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;6.<u>Payment of Salary and Receipt of All Benefits</u>. Employee acknowledges and represents that, other than the consideration set forth in this Agreement, the Company and its agents have paid or provided all salary, wages, bonuses, accrued vacation/paid time off, notice periods, premiums, leaves, housing allowances, relocation costs, interest, severance, outplacement costs, fees, reimbursable expenses, commissions, stock, stock options, vesting, and any and all other benefits and compensation due to Employee. Employee understands and acknowledges that, separate from this Agreement and the Supplemental Release Agreement, Employee will be paid his 2022 annual bonus from the Company in an amount determined by the Company's Board of Directors or applicable committee of the Board of Directors, and that other than such bonus payment, and the consideration set forth in section 1 of this Agreement (that is contingent on this Agreement and the Supplemental Release), Employee is not and will not be entitled to any severance payments or benefits (or any other payments, compensation, or benefits, including, without limitation, any bonus payments) from the Company.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;7.<u>Release of Claims</u>. Employee agrees that the consideration hereof represents settlement in full of all outstanding obligations owed to Employee by the Company and its current and former officers, directors, employees, agents, investors, attorneys, shareholders, administrators, affiliates, benefit plans, plan administrators, professional employer organization or co-employer, insurers, trustees, divisions, and subsidiaries, and predecessor and successor corporations and assigns (collectively, the "**Releasees**"). Employee, on Employee's own behalf and on behalf of Employee's respective heirs, family members, executors, agents, and assigns, hereby and forever releases the Releasees from, and agrees not to sue concerning, or in any manner to institute, prosecute, or pursue, any claim, complaint, charge, duty, obligation,

------

or cause of action relating to any matters of any kind, whether presently known or unknown, suspected or unsuspected, that Employee may possess against any of the Releasees arising from any omissions, acts, facts, or damages that have occurred up until and including the date Employee signs this Agreement, including, without limitation:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;a. any and all claims relating to or arising from Employee's employment relationship with the Company, the decision to terminate that relationship, and the termination of that relationship;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;b. any and all claims relating to, or arising from, Employee's right to purchase, or actual purchase of shares of stock of the Company, including, without limitation, any claims for fraud, misrepresentation, breach of fiduciary duty, breach of duty under applicable state corporate law, and securities fraud under any state or federal law;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;c. any and all claims under the law of any jurisdiction, including, but not limited to, wrongful discharge of employment; constructive discharge from employment; termination in violation of public policy; discrimination; harassment; retaliation; breach of contract, both express and implied; breach of covenant of good faith and fair dealing, both express and implied; promissory estoppel; negligent or intentional infliction of emotional distress; fraud; negligent or intentional misrepresentation; negligent or intentional interference with contract or prospective economic advantage; unfair business practices; defamation; libel; slander; negligence; personal injury; assault; battery; invasion of privacy; false imprisonment; conversion; and disability benefits;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;d. any and all claims for violation of any federal, state, or municipal statute, including, but not limited to, the following, each as may be amended, and except as prohibited by law: Title VII of the Civil Rights Act of 1964; the Civil Rights Act of 1991; the Rehabilitation Act of 1973; the Americans with Disabilities Act of 1990; the Equal Pay Act; the Fair Labor Standards Act; the Fair Credit Reporting Act; the Employee Retirement Income Security Act of 1974; the Worker Adjustment and Retraining Notification Act; the Family and Medical Leave Act; the Uniformed Services Employment and Reemployment Rights Act; the Immigration Reform and Control Act; and the National Labor Relations Act; the Texas Payday Act; the Texas Workers' Compensation Act; and Chapter 21 of the Texas Labor Code (also known as the Texas Commission on Human Rights Act);

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;e. any and all claims for violation of the federal or any state constitution;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;f. any and all claims arising out of any other laws and regulations relating to employment or employment discrimination;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;g. any claim for any loss, cost, damage, or expense arising out of any dispute over the nonwithholding or other tax treatment of any of the proceeds received by Employee as a result of this Agreement; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;h. any and all claims for attorneys' fees and costs.

Employee agrees that the release set forth in this section shall be and remain in effect in all respects as a complete general release as to the matters released. This release does not extend to any obligations incurred under this Agreement. This release does not release claims that cannot be released as a matter of law. Any and all disputed wage claims that are released herein shall be subject to binding arbitration except as required by applicable law. This release does not extend to any right Employee may have to unemployment compensation benefits or workers' compensation benefits. Further, notwithstanding any of the foregoing, nothing in this Agreement releases any rights or claims Employee may have under the Age Discrimination in Employment

------

Act, or the Older Workers Benefit Protection Act, but such claims will be released pursuant to the execution and non-revocation of the Supplemental Release.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;8.<u>Unknown Claims.</u> Employee acknowledges that he has been advised to consult with legal counsel and that he is familiar with the principle that a general release does not extend to claims that the releaser does not know or suspect to exist in his favor at the time of executing the release, which, if known by him, must have materially affected his settlement with the releasee. Employee, being aware of said principle, agrees to expressly waive any rights he may have to that effect, as well as under any other statute or common law principles of similar effect.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;9.<u>Application for Employment</u>. Employee understands and agrees that, as a condition of this Agreement, Employee shall not be entitled to any employment with the Company, and Employee hereby waives any right, or alleged right, of employment or re-employment with the Company.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;10.<u>Trade Secrets and Confidential Information/Company Property; Insider Trading Policy</u>. Employee reaffirms and agrees to observe and abide by the terms of the Confidentiality Agreement, including but not limited to the provisions therein regarding nondisclosure of the Company's trade secrets and confidential and proprietary information. Employee agrees to return, as of a date determined by the CEO, all documents and other items provided to Employee by the Company, developed or obtained by Employee in connection with Employee's employment with the Company, or otherwise belonging to the Company, including, but not limited to, all passwords to any software or other programs or data that Employee used in performing services for the Company. Employee acknowledges and agrees to comply, at all times, with the terms of the Company's insider trading policy.

Employee agrees and acknowledges that failure to abide with the covenants in the Confidentiality Agreement and this Agreement would be a basis for the Company to terminate Employee's employment with the Company prior to the anticipated Separation Date and would result in the Company not being obligated to pay or provide the severance benefits set forth in Section 1.b.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;11.<u>Breach</u>. In addition to the rights provided in the "Attorneys' Fees" section below, Employee acknowledges and agrees that any material breach of this Agreement or the Supplemental Release (unless such breach constitutes a legal action by Employee challenging or seeking a determination in good faith of the validity of the waiver under the ADEA in the Supplemental Release) or of any provision of the Confidentiality Agreement, shall entitle the Company immediately to recover and/or cease providing the consideration provided to Employee under this Agreement and to obtain damages, except as provided by law, provided, however, that the Company shall not recover One Hundred Dollars ($100.00) of the consideration already paid pursuant to Section 1.b of this Agreement, and such amount shall serve as full and complete consideration for the promises and obligations assumed by Employee under this Agreement and the Confidentiality Agreement.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;12.<u>No Admission of Liability</u>. Employee understands and acknowledges that this Agreement constitutes a compromise and settlement of any and all actual or potential disputed claims by Employee. No action taken by the Company hereto, either previously or in connection with this Agreement, shall be deemed or construed to be (a) an admission of the truth or falsity of any actual or potential claims or (b) an acknowledgment or admission by the Company of any fault or liability whatsoever to Employee or to any third party.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;13.<u>Costs</u>. The Parties shall each bear their own costs, attorneys' fees, and other fees incurred in connection with the preparation of this Agreement and the Supplemental Release.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;14.<u>Tax Consequences</u>. The Company makes no representations or warranties with respect to the tax consequences of the payments and any other consideration provided to Employee or made on Employee's

------

behalf under the terms of this Agreement or the Supplemental Release. Employee agrees and understands that Employee is responsible for payment, if any, of local, state, and/or federal taxes on the payments and any other consideration provided hereunder by the Company and any penalties or assessments thereon. Employee further agrees to indemnify and hold the Releasees harmless from any claims, demands, deficiencies, penalties, interest, assessments, executions, judgments, or recoveries by any government agency against the Company for any amounts claimed due on account of (a) Employee's failure to pay or delayed payment of, federal or state taxes, or (b) damages sustained by the Company by reason of any such claims, including attorneys' fees and costs.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;15.<u>Authority</u>. The Company represents and warrants that the undersigned has the authority to act on behalf of the Company and to bind the Company and all who may claim through it to the terms and conditions of this Agreement. Employee represents and warrants that Employee has the capacity to act on Employee's own behalf and on behalf of all who might claim through Employee to bind them to the terms and conditions of this Agreement. Each Party warrants and represents that there are no liens or claims of lien or assignments in law or equity or otherwise of or against any of the claims or causes of action released herein.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;16.<u>Protected Activity Not Prohibited</u>. Employee understands that nothing in this Agreement shall in any way limit or prohibit Employee from engaging in any Protected Activity.

Employee further understands that Protected Activity does not include the disclosure of any Company attorney-client privileged communications or attorney work product. Any language in the Confidentiality Agreement regarding Employee's right to engage in Protected Activity that conflicts with, or is contrary to, this section is superseded by this Agreement.

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.

Each payment and benefit to be paid or provided under this Agreement is intended to constitute a series of separate payments for purposes of Section 1.409A-2(b)(2) of the Treasury Regulations. The Company and Employee will work together in good faith to consider either (i) amendments to this Agreement; or (ii) revisions to this Agreement with respect to the payment of any awards, which are necessary

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;21.<u>Attorneys' Fees</u>. Except with regard to a legal action challenging or seeking a determination in good faith of the validity of the ADEA waiver in the Supplemental Release, in the event that either Party brings an action to enforce or effect its rights under this Agreement or the Supplemental Release, the prevailing Party shall be entitled to recover its costs and expenses, including the costs of mediation, arbitration, litigation, court fees, and reasonable attorneys' fees incurred in connection with such an action.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;22.<u>Entire Agreement</u>. This Agreement, together with the Supplemental Release, represents the entire agreement and understanding between the Company and Employee concerning the subject matter of this Agreement and the Supplemental Release and Employee's employment with and separation from the Company and the events leading thereto and associated therewith, and supersedes and replaces any and all prior agreements and understandings concerning the subject matter of this Agreement and the Supplemental Release and Employee's relationship with the Company (including, for example, the Employment Agreement), but with the exception of the Confidentiality Agreement and the Stock Agreements.

Employee agrees that Employee will not file any legal action asserting any such claims released herein. Employee agrees that the release set forth in this section shall be and remain in effect in all respects as a complete general release as to the matters released.
