RECITALS

WHEREAS, Executive was employed by the Company as its Chief Executive Officer;

WHEREAS, Executive signed an Executive Employment Agreement effective as of April 3, 2017, as amended on August 12, 2021 (together, the “Employment Agreement”);

WHEREAS, Executive signed an At-Will Employment, Confidential Information, Invention Assignment, and Arbitration Agreement with the Company (the “Confidentiality Agreement”);

WHEREAS, Executive’s employment with the Company is being terminated effective September 19, 2022 (the “Separation Date”); and

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

COVENANTS

1. Consideration. Subject to Executive’s execution and non-revocation of this Agreement, and Executive’s continued compliance with the terms of this Agreement and the Confidentiality Agreement:

a. Severance Payment. The Company agrees to pay Executive a total of Seven Hundred and Eight Thousand Seven Hundred and Fifty Dollars ($708,750), at the rate of Forty Seven Thousand Two Hundred and Fifty Dollars ($47,250) per month, less applicable withholdings, for fifteen (15) months from the Separation Date, in accordance with the Company’s regular payroll practices, with the first payment paid on the first regular payroll date following the Effective Date and to include any amounts that that otherwise would have been paid between the Separation Date and the first payment date.

b. Health Care Coverage Payment. The Company agrees to pay Executive a total of Forty Five Thousand Nine Hundred Sixty-Two Dollars and Seventy Cents ($45,962.70), at the rate of Three Thousand Sixty-Four Dollars and Eighteen Cents ($3,064.18) per month, less applicable withholdings, for fifteen (15) months from the Separation Date, in accordance with the Company’s regular payroll practices, with the first payment paid on the first regular payroll date following the Effective Date and to include any amounts that that otherwise would have been paid between the Separation Date and the first payment date. In addition, the Company agrees to reimburse the Executive for the amounts he pays to continue his other Company provided health and welfare benefits (vision, dental, and life insurance) under applicable law (COBRA) for fifteen (15) months, provided Executive timely elects and pays for continued coverage pursuant to COBRA, with such reimbursement to be made within thirty (30) days of submission of proof of payment, but only if proof of payment is submitted within thirty (30) days of Executive paying the applicable premium.

c. Bonus. The Company agrees to pay Executive a pro-rated Target Bonus (as defined in the Employment Agreement) for the 2022 fiscal year, where the proration is based on the number of days between the start of the 2022 fiscal year and September 30, 2022. Payment pursuant to this Section 1.c will be subject to the Company’s Board of Directors (the “Board”) (or an authorized committee of the Board) determining, in good faith, that any applicable performance objectives have been achieved and, if earned, paid to Executive on the same day that 2022 annual bonuses are paid to continuing Company employees, but in no event will any such annual bonus be paid after the later of (i) the fifteenth (15th) day of the third (3rd) month following the close of the Company’s fiscal year in which such bonus is earned or (ii) March 15 following the calendar year in which such bonus is earned.

d. Post-Termination Exercise Period.

i. Extension of Exercise Period. The Company agrees that, effective as of the Effective Date, the equity awards set forth on Exhibit A (the “Options”) will each be amended to provide that Executive has the right to exercise the vested portion of each Option until the earlier of (x) two (2) years following the date that he is no longer a Service Provider to the Company (as defined in the applicable equity incentive plan), or (y) the expiration of the term of such Option, subject in each case to earlier termination in accordance with the terms of the applicable equity incentive plan (the “Options Amendment”).

ii. Tax Implications. Executive acknowledges and agrees that the Options Amendment is a “modification” of the Options resulting in the deemed re-grant of the Options for purposes of the rules governing Incentive Stock Options under Section 422 of the Code. As a result, the Options otherwise characterized as Incentive Stock Options have converted into Nonstatutory Stock Options for tax purposes as of the Effective Date. Upon the exercise of any of the Options, Executive will be treated as having received compensation income from the Company (taxable at ordinary income tax rates) equal to the excess, if any, of the aggregate fair market value of the exercised shares on the date of exercise over their aggregate exercise price. In that case, in addition to the payment of the aggregate exercise price, Executive’s exercise of any Options is conditioned on payment to the Company of applicable federal, state and other withholding obligations incurred upon exercise. Executive acknowledges and agrees that Executive remains solely responsible for all employee-related withholdings associated with the exercise of the unexercised Options. The Company has advised the Executive to consult with Executive’s own tax advisor regarding the tax status of the Options and the tax consequences to the Executive of Executive’s exercise of the Options and disposition of any shares acquired upon such exercise.

e. Reimbursement of Costs and Fees. The Company shall reimburse Executive for reasonable costs and attorney’s fees in connection with the preparation of this Agreement not to exceed $15,000 in the aggregate.

f. Acknowledgement. Executive acknowledges that without this Agreement, Executive is otherwise not entitled to the consideration listed in this Section 1.

2. Termination. Executive’s employment with the Company is being terminated as of the Separation Date. Executive agrees to promptly execute any instruments, forms or other documents evidencing the termination of his employment as a matter of state, federal, or foreign law.

3. Board Position. The Parties agree that Executive shall continue to be a member of the Board following the Separation Date until the expiration of the term for which he was elected and any subsequent term for which he is nominated and elected to the Board, or until Executive’s earlier death, resignation or removal, and shall continue to vest in any outstanding equity awards from the Company pursuant to the terms and

conditions of any applicable equity agreements between Executive and the Company. Furthermore, in the event Executive otherwise would incur a termination of Continuous Service (as defined in the Company’s Amended 2011 Equity Incentive Plan) or cease to be a Service Provider (as defined in the Company’s 2021 Equity Incentive Plan) prior to the vesting of all of the Stock Options set forth on Exhibit A due to the Executive’s removal from the Board for any reason other than his voluntary resignation, his death, or for Cause, the Company shall appoint Executive to its Scientific Advisory Board so that Executive shall not have a termination of Continuous Service and shall continue as a Service Provider for purposes of continued vesting of the Stock Options, with Executive remaining in Continuous Service as a Service Provider pursuant to his services as a member of the Scientific Advisory Board though the date on which the Stock Options have vested in full or his earlier voluntary resignation from the Scientific Advisory Board, death or removal from the Scientific Advisory Board for Cause. For purposes of this Agreement, “Cause” shall mean: (i) an act of dishonesty made by Executive in connection with Executive’s responsibilities as a member of the Board or the Scientific Advisory Board; (ii) Executive’s conviction of, or plea of nolo contendere to, a felony or any crime involving fraud, embezzlement or any other act of moral turpitude; (iii) Executive’s gross misconduct; (iv) Executive’s unauthorized use or disclosure of any proprietary information or trade secrets of the Company or any other party to whom Executive owes an obligation of nondisclosure as a result of Executive’s relationship with the Company; (v) Executive’s willful breach of any obligations under any written agreement or covenant with the Company; or (vi) Executive’s continued failure to perform Executive’s Board or Scientific Advisory Board duties after Executive has received a written demand of performance from the Company with specifically sets forth the factual basis for the Company’s belief that Executive has not substantially performed Executive’s duties and has failed to cure such non-performance to the Company’s satisfaction within 10 business days after receiving such notice.

4. Payment of Salary and Receipt of All Benefits. Executive’s participation in all benefits and incidents of employment, including, but not limited to, the accrual of bonuses, vacation, and paid time off, will cease as of the Separation Date. Other than (i) the base salary otherwise payable to Executive for employment on and after September 1, 2022, (ii) Executive’s wellness (gym) benefit reimbursement for September, and (iii) payment for Executive’s accrued, but unused, vacation/paid-time off, (all of the foregoing amounts to be paid in the ordinary course), Executive acknowledges and represents that the Company has paid or provided all salary, wages, bonuses, premiums, leaves, housing allowances, relocation costs, interest, severance, outplacement costs, fees, reimbursable expenses, commissions, and any and all other benefits and compensation due to Executive as of the signature date below.

5. Release of Claims. Executive agrees that the foregoing consideration represents settlement in full of all outstanding obligations owed to Executive 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, subsidiaries, predecessor and successor corporations, and assigns (collectively, the “Releasees”). Executive, on Executive’s own behalf and on behalf of Executive’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, demand, or cause of action relating to any matters of any kind, whether presently known or unknown, suspected or unsuspected, that Executive may possess against any of the Releasees arising from any omissions, acts, facts, or damages that have occurred up until and including the date Executive signs this Agreement, including, without limitation:

This release does not waive any rights available to Executive under the Indemnification Agreement signed between the Parties on February 24, 2021 (the “Indemnification Agreement”). This release does not release claims Executive may have in connection with his status as a stockholder. Any and all disputed wage claims that are released herein shall be subject to binding arbitration in accordance with this Agreement, except as required by applicable law. This release does not extend to any right Executive may have to unemployment compensation benefits.

6. Acknowledgment of Waiver of Claims under ADEA. Executive acknowledges that Executive is waiving and releasing any rights Executive may have under the Age Discrimination in Employment Act of 1967 (“ADEA”), and that this waiver and release is knowing and voluntary. Executive agrees that this waiver and release does not apply to any rights or claims that may arise under the ADEA after the date Executive signs this Agreement. Executive acknowledges that the consideration given for this waiver and release is in addition to anything of value to which Executive was already entitled. Executive further acknowledges that Executive has been advised by this writing that: (a) Executive should consult with an attorney prior to executing this Agreement; (b) Executive has twenty-one (21) days within which to consider this Agreement; (c) Executive has seven (7) days following Executive’s execution of this Agreement to revoke this Agreement; (d) this Agreement

shall not be effective until after the revocation period has expired; and (e) nothing in this Agreement prevents or precludes Executive from challenging or seeking a determination in good faith of the validity of this waiver under the ADEA, nor does it impose any condition precedent, penalties, or costs for doing so, unless specifically authorized by federal law. In the event Executive signs this Agreement and returns it to the Company in less than the 21-day period identified above, Executive hereby acknowledges that Executive has knowingly and voluntarily chosen to waive the time period allotted for considering this Agreement. Executive acknowledges and understands that revocation must be accomplished by a written notification to the person executing this Agreement on the Company’s behalf that is received prior to the Effective Date. The Parties agree that changes, whether material or immaterial, do not restart the running of the 21-day period.

7. California Civil Code Section 1542. Executive acknowledges that Executive has been advised to consult with legal counsel and is familiar with the provisions of California Civil Code Section 1542, a statute that otherwise prohibits the release of unknown claims, which provides as follows:

A GENERAL RELEASE DOES NOT EXTEND TO CLAIMS THAT THE CREDITOR OR RELEASING PARTY DOES NOT KNOW OR SUSPECT TO EXIST IN HIS OR HER FAVOR AT THE TIME OF EXECUTING THE RELEASE AND THAT, IF KNOWN BY HIM OR HER, WOULD HAVE MATERIALLY AFFECTED HIS OR HER SETTLEMENT WITH THE DEBTOR OR RELEASED PARTY.

Executive, being aware of said code section, agrees to expressly waive any rights Executive may have thereunder, as well as under any other statute or common law principles of similar effect.

8. No Pending or Future Lawsuits. Executive represents that Executive has no lawsuits, claims, or actions pending in Executive’s name, or on behalf of any other person or entity, against the Company or any of the other Releasees. Executive also represents that Executive does not currently intend to bring any claims on Executive’s own behalf or on behalf of any other person or entity against the Company or any of the other Releasees.

9. Application for Employment. Executive understands and agrees that, as a condition of this Agreement, Executive shall not be entitled to any employment with the Company, and Executive hereby waives any right, or alleged right, of employment or re-employment with the Company.

10. Trade Secrets and Confidential Information/Company Property. Executive agrees at all times hereafter to hold in the strictest confidence, and not to use or disclose to any person or entity, any Confidential Information of the Company. Executive understands that “Confidential Information” means any Company or associated third party proprietary information, technical data, trade secrets or know-how, including, but not limited to, research, product plans, products, services, customer lists and customers (including, but not limited to, customers of the Company on whom Executive has called or with whom Executive became acquainted during the term of Executive’s employment), markets, software, developments, inventions, processes, formulas, technology, designs, drawings, engineering, hardware configuration information, marketing, finances, or other business information disclosed to Executive by the Company either directly or indirectly, in writing, orally, or by drawings or observation of parts or equipment. Executive further understands that Confidential Information does not include any of the foregoing items that have become publicly known and made generally available through no wrongful act of Executive’s or of others who were under confidentiality obligations as to the item or items involved or improvements or new versions thereof. Executive hereby grants consent to notification by the Company to any new employer about Executive’s obligations under this section. Executive represents that Executive has not to date misused or disclosed Confidential Information to any unauthorized party. Executive acknowledges that the Company will not enforce the post-employment non-solicitation restrictions in the Confidentiality Agreement; provided, however, that Executive remains bound by all other continuing

Executive’s signature below constitutes Executive’s certification under penalty of perjury that Executive has returned all documents and other items provided to Executive by the Company, developed or obtained by Executive in connection with Executive’s employment with the Company, or otherwise belonging to the Company, except as stated herein. Specifically, Executive may retain a copy of the Employee Handbook and personnel documents specifically relating to Executive. In addition, during the period in which Executive continues to serve as a member of the Board or is otherwise a Company service provider, subject to his continuing obligations under the Confidentiality Agreement (as amended herein) and this Agreement, applicable Company security and cybersecurity policies as may be amended or adopted from time to time, and other applicable legal obligations, Executive will: (i) have access to, and may continue using, his Company-provided email account, (ii) retain his Company-issued desktop computer and have continued access to the Company’s Active Directory Controlled Network accessible folder, and (iii) retain his Company-issued phone and phone number.

11. Invention Assignment.

a. Inventions Defined. “Inventions” means inventions, original works of authorship, developments, concepts, improvements, designs, discoveries, ideas, know-how, trademarks, and trade secrets, whether or not patentable or registrable under copyright or similar laws, that Executive solely or jointly authored, conceived, developed, or reduced to practice.

b. Assignment of Inventions and Works Made for Hire. Executive hereby assigns to Company, or its designee, all of Executive’s right, title, and interest (including all related intellectual property rights) in all Inventions that Executive created during the period of time Executive was in the employ of the Company (including during off-duty hours) (“Company Inventions”). In addition, Executive acknowledges that all original works of authorship that were made by Executive (solely or jointly with others) within the scope of and during the period of Executive’s employment with Company and that are protectable by copyright are “works made for hire,” as that term is defined in the United States Copyright Act, and in accordance, the Company is considered the author of these works.

c. Exception to Assignments. EXECUTIVE ACKNOWLEDGES AND UNDERSTANDS THAT THE PROVISIONS OF THIS AGREEMENT REQUIRING ASSIGNMENT OF INVENTIONS TO COMPANY DO NOT APPLY TO ANY INVENTION THAT QUALIFIES FULLY UNDER THE PROVISIONS OF CALIFORNIA LABOR CODE SECTION 2870. California Labor Code section 2870 provides: “(a) Any provision in an employment agreement which provides that an employee shall assign, or offer to assign, any of his or her rights in an invention to his or her employer shall not apply to an invention that the employee developed entirely on his or her own time without using the employer’s equipment, supplies, facilities, or trade secret information except for those inventions that either: (1) Relate at the time of conception or reduction to practice of the invention to the employer’s business, or actual or demonstrably anticipated research or development of the employer; or (2) Result from any work performed by the employee for the employer. (b) To the extent a provision in an employment agreement purports to require an employee to assign an invention otherwise excluded from being required to be assigned under subdivision (a), the provision is against the public policy of this state and is unenforceable.”

d. Outside Inventions. Executive acknowledges that Executive has not incorporated any inventions, discoveries, ideas, original works of authorship, developments, improvements, trade secrets and other proprietary information or intellectual property rights owned by any third party into any Company Invention without the Company’s prior written permission. Executive acknowledges that Executive has informed the Company, in writing, before incorporating any inventions, discoveries, ideas, original works of authorship, developments, improvements, trade secrets and other proprietary information or intellectual property

rights owned by Executive or in which Executive has an interest prior to, or separate from, Executive’s employment with the Company, including, without limitation, any such inventions that are subject to California Labor Code Section 2870 (“Outside Inventions”) into any Company Invention or otherwise utilizing any Outside Invention in the course of Executive’s employment with the Company; and the Company is hereby granted a nonexclusive, royalty-free, perpetual, irrevocable, transferable worldwide license (with the right to grant and authorize sublicenses) to make, have made, use, import, offer for sale, sell, reproduce, distribute, modify, adapt, prepare derivative works of, display, perform, and otherwise exploit any such incorporated or utilized Outside Inventions, without restriction, including, without limitation, as part of, or in connection with, such Invention, and to practice any method related thereto.

e. Moral Rights. Any assignment to the Company of Company Inventions includes all rights of attribution, paternity, integrity, modification, disclosure and withdrawal, and any other rights throughout the world that may be known as or referred to as “moral rights,” “artist’s rights,” or the like (collectively, “Moral Rights”). If Moral Rights cannot be assigned under applicable law, Executive hereby waives and agrees not to enforce any and all Moral Rights, including any limitation on subsequent modification, to the extent permitted under applicable law.

f. Further Assurances. Executive will assist the Company, or its designee, at Company’s expense, in every proper way to secure and protect the Company’s rights in Company Inventions and any related copyrights, patents, mask work rights, or other intellectual property rights in any and all countries. Executive will disclose to Company all pertinent information and data. Executive will execute all applications, specifications, oaths, assignments, and all other instruments that Company deems necessary in order to apply for and obtain these rights and in order to deliver, assign, and convey to Company, its successors, assigns, and nominees the sole and exclusive rights, title, and interest in and to Company Inventions, and any related copyrights, patents, mask work rights, or other intellectual property rights. Executive will testify in a suit or other proceeding relating to such Company Inventions and any rights relating thereto.

12. No Cooperation. Subject to the Protected Activity Not Prohibited section, Executive agrees that Executive will not knowingly encourage, counsel, or assist any attorneys or their clients in the presentation or prosecution of any disputes, differences, grievances, claims, charges, or complaints by any third party against any of the Releasees, unless under a subpoena or other court order to do so or upon written request from an administrative agency or the legislature or as related directly to the ADEA waiver in this Agreement Executive agrees both to immediately notify the Company upon receipt of any such subpoena or court order or written request from an administrative agency or the legislature, and to furnish, within three (3) business days of its receipt, a copy of such subpoena or other court order or written request from an administrative agency or the legislature. If approached by anyone for counsel or assistance in the presentation or prosecution of any disputes, differences, grievances, claims, charges, or complaints against any of the Releasees, Executive shall state no more than that Executive cannot provide counsel or assistance.

13. Protected Activity Not Prohibited. Executive understands that nothing in this Agreement shall in any way limit or prohibit Executive from engaging in any Protected Activity. Protected Activity includes: (i) filing and/or pursuing a charge, complaint, or report with, or otherwise communicating, cooperating, or participating in any investigation or proceeding that may be conducted by any federal, state or local government agency or commission, including the Securities and Exchange Commission, the Equal Employment Opportunity Commission, the Occupational Safety and Health Administration, and the National Labor Relations Board (“Government Agencies”); and/or (ii) discussing or disclosing information about unlawful acts in the workplace, such as harassment or discrimination or any other conduct that Executive has reason to believe is unlawful. Executive understands that in connection with such Protected Activity, Executive is permitted to disclose documents or other information as permitted by law, without giving notice to, or receiving authorization from, the Company. Notwithstanding the foregoing, Executive agrees to take all reasonable

precautions to prevent any unauthorized use or disclosure of any Company trade secrets, proprietary information, or confidential information that does not involve unlawful acts in the workplace or the activity otherwise protected herein. Executive 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 Executive’s right to engage in Protected Activity that conflicts with, or is contrary to, this section is superseded by this Agreement. In addition, pursuant to the Defend Trade Secrets Act of 2016, Executive 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 (i) 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 (ii) 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.

14. Mutual Nondisparagement. Subject to the Protected Activity Not Prohibited section, Executive agrees to refrain from any disparagement, defamation, libel, or slander of any of the Releasees, and agrees to refrain from any tortious interference with the contracts and relationships of any of the Releasees. Similarly, the Company agrees to refrain from any disparagement, defamation, libel or slander of Executive. Executive understands that the Company’s obligations under this paragraph extend only to the Company’s current executive officers and members of its Board of Directors and only for so long as each officer or member is an employee or director of the Company. Executive shall direct any inquiries by potential future employers to the Company’s human resources department.

15. Breach. In addition to the rights provided in the “Attorneys’ Fees” section below, Executive acknowledges and agrees that any material breach of this Agreement, unless such breach constitutes a legal action by Executive challenging or seeking a determination in good faith of the validity of the waiver herein under the ADEA, or of any provision of the Confidentiality Agreement (as amended herein) shall entitle the Company immediately to recover and/or cease providing the consideration provided to Executive under this Agreement and to obtain damages, except as provided by law.

16. No Admission of Liability. Executive understands and acknowledges that with respect to all claims released herein, this Agreement constitutes a compromise and settlement of any and all actual or potential disputed claims by Executive unless such claims were explicitly not released by the release in this Agreement. 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 Executive or to any third party.

17. ARBITRATION. EXCEPT AS PROHIBITED BY LAW, THE PARTIES AGREE THAT ANY AND ALL DISPUTES ARISING OUT OF THE TERMS OF THIS AGREEMENT, THEIR INTERPRETATION, EXECUTIVE’S EMPLOYMENT WITH THE COMPANY OR THE TERMS THEREOF, OR ANY OF THE MATTERS HEREIN RELEASED, SHALL BE SUBJECT TO ARBITRATION UNDER THE FEDERAL ARBITRATION ACT (THE “FAA”) AND THAT THE FAA SHALL GOVERN AND APPLY TO THIS ARBITRATION AGREEMENT WITH FULL FORCE AND EFFECT; HOWEVER, WITHOUT LIMITING ANY PROVISIONS OF THE FAA, A MOTION OR PETITION OR ACTION TO COMPEL ARBITRATION MAY ALSO BE BROUGHT IN STATE COURT UNDER THE PROCEDURAL PROVISIONS OF SUCH STATE’S LAWS RELATING TO MOTIONS OR PETITIONS OR ACTIONS TO COMPEL ARBITRATION. EXECUTIVE AGREES THAT, TO THE FULLEST EXTENT PERMITTED BY

LAW, EXECUTIVE MAY BRING ANY SUCH ARBITRATION PROCEEDING ONLY IN EXECUTIVE’S INDIVIDUAL CAPACITY. ANY ARBITRATION WILL OCCUR IN SAN DIEGO COUNTY, BEFORE JAMS, PURSUANT TO ITS EMPLOYMENT ARBITRATION RULES & PROCEDURES (“JAMS RULES”), EXCEPT AS EXPRESSLY PROVIDED IN THIS SECTION. THE PARTIES AGREE THAT THE ARBITRATOR SHALL HAVE THE POWER TO DECIDE ANY MOTIONS BROUGHT BY ANY PARTY TO THE ARBITRATION, INCLUDING MOTIONS FOR SUMMARY JUDGMENT AND/OR ADJUDICATION, AND MOTIONS TO DISMISS AND DEMURRERS, APPLYING THE STANDARDS SET FORTH UNDER THE CALIFORNIA CODE OF CIVIL PROCEDURE. THE PARTIES AGREE THAT THE ARBITRATOR SHALL ISSUE A WRITTEN DECISION ON THE MERITS. THE PARTIES ALSO AGREE THAT THE ARBITRATOR SHALL HAVE THE POWER TO AWARD ANY REMEDIES AVAILABLE UNDER APPLICABLE LAW, AND THAT THE ARBITRATOR MAY AWARD ATTORNEYS’ FEES AND COSTS TO THE PREVAILING PARTY, WHERE PERMITTED BY APPLICABLE LAW. THE ARBITRATOR MAY GRANT INJUNCTIONS AND OTHER RELIEF IN SUCH DISPUTES. THE DECISION OF THE ARBITRATOR SHALL BE FINAL, CONCLUSIVE, AND BINDING ON THE PARTIES TO THE ARBITRATION. THE PARTIES AGREE THAT THE PREVAILING PARTY IN ANY ARBITRATION SHALL BE ENTITLED TO INJUNCTIVE RELIEF IN ANY COURT OF COMPETENT JURISDICTION TO ENFORCE THE ARBITRATION AWARD. THE PARTIES TO THE ARBITRATION SHALL EACH PAY AN EQUAL SHARE OF THE COSTS AND EXPENSES OF SUCH ARBITRATION, AND EACH PARTY SHALL SEPARATELY PAY FOR ITS RESPECTIVE COUNSEL FEES AND EXPENSES; PROVIDED, HOWEVER, THAT THE ARBITRATOR MAY AWARD ATTORNEYS’ FEES AND COSTS TO THE PREVAILING PARTY, EXCEPT AS PROHIBITED BY LAW. THE PARTIES HEREBY AGREE TO WAIVE THEIR RIGHT TO HAVE ANY DISPUTE BETWEEN THEM RESOLVED IN A COURT OF LAW BY A JUDGE OR JURY. NOTWITHSTANDING THE FOREGOING, THIS SECTION WILL NOT PREVENT EITHER PARTY FROM SEEKING INJUNCTIVE RELIEF (OR ANY OTHER PROVISIONAL REMEDY) FROM ANY COURT HAVING JURISDICTION OVER THE PARTIES AND THE SUBJECT MATTER OF THEIR DISPUTE RELATING TO THIS AGREEMENT AND THE AGREEMENTS INCORPORATED HEREIN BY REFERENCE. SHOULD ANY PART OF THE ARBITRATION AGREEMENT CONTAINED IN THIS SECTION CONFLICT WITH ANY OTHER ARBITRATION AGREEMENT BETWEEN THE PARTIES, INCLUDING, BUT NOT LIMITED TO THE ARBITRATION SECTION OF THE CONFIDENTIALITY AGREEMENT, THE PARTIES AGREE THAT THIS ARBITRATION AGREEMENT IN THIS SECTION SHALL GOVERN.

18. Tax Consequences. The Company makes no representations or warranties with respect to the tax consequences of the payments and any other consideration provided to Executive or made on Executive’s behalf under the terms of this Agreement. The Parties agree and acknowledge that the payments made pursuant to section 1 of this Agreement are not related to sexual harassment or sexual abuse and not intended to fall within the scope of 26 U.S.C. Section 162(q). The Company shall withhold on the payments to be made hereunder in accordance with applicable law.

19. Section 409A. It is intended that this Agreement comply with, or be exempt from, Code Section 409A and the final regulations and official guidance thereunder (“Section 409A”) and any ambiguities herein will be interpreted to so comply and/or be exempt from Section 409A. 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 Executive 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 or appropriate to avoid imposition of any additional tax or income recognition prior to the actual payment to Executive under Section 409A. In no event will the Releasees reimburse Executive for any taxes that may be imposed on Executive as a result of Section 409A. The parties acknowledge and agree that the termination of Executive’s employment constitutes a “separation from service” under Section 409A of the Code. Notwithstanding anything to the contrary in this Agreement, if Executive is a

“specified employee” within the meaning of Section 409A at the time of Executive’s termination of employment (other than due to death), and if necessary to avoid the imputation of additional tax, whether in the form of excise taxes or otherwise, pursuant to Section 409A, then all amounts payable hereunder that are considered deferred compensation under Section 409A (“Deferred Compensation Separation Benefits”) that are payable within the first six (6) months following Executive’s separation from service, will become payable on the first payroll date that occurs on or after the date six (6) months and one (1) day following the date of Executive’s separation from service. Notwithstanding anything herein to the contrary, if Executive dies following Executive’s separation from service, but prior to the six (6) month anniversary of the separation from service, then any payments delayed in accordance with this paragraph will be payable in a lump sum as soon as administratively practicable after the date of Executive’s death and all other Deferred Compensation Separation Benefits will be payable in accordance with the payment schedule applicable to each payment or benefit.

20. Authority. 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. Executive represents and warrants that Executive has the capacity to act on Executive’s own behalf and on behalf of all who might claim through Executive 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.

21. Severability.
