written notice to you at any time without cause upon 30 days written notice to you. The Company may terminate this Agreement for Cause (as hereinafter defined) at any time upon written notice to you. Cause as used in this Agreement means
that you, (i) after reasonable notice and warning, have failed to perform your assigned duties as defined in this Agreement, with such failure to be determined by the Board of Directors, (ii) have materially breached any of the terms or
conditions of this Agreement and have failed to correct such breach within five days following written notice from the Company of such breach, or (iii) have been charged with a felony or any intentionally fraudulent act that materially damages,

unless regulated otherwise by the mandatory law of the State of California. You also agree and warrant that you will not use or incorporate third party proprietary materials into Inventions,
disclose third party proprietary information to the Company or knowingly engage in any activities or use any facilities in the course of providing services under this Agreement that could result in claims of ownership to any Inventions being made by
any third party.

9. Arbitration. In the event of any dispute under this Agreement, such dispute shall be
resolved by binding arbitration with JAMS/ENDISPUTE in Los Angeles, California. The arbitrator shall be a retired judge with at least five years of experience on the bench. This provision shall not be interpreted so as to require arbitration of
claims that the state and/or Federal Courts of California have ruled may not be the subjects of compelled arbitration in employment matters, nor shall it be interpreted so as to restrict any remedy, right of appeal or discovery device available to
either party in a manner that violates the rulings of the state and/or Federal Courts of California with respect to employment-related arbitration. This provision shall not be interpreted so as to preclude the making of reports to governmental
offices, or to preclude either party from seeking injunctive or provisional relief in a court of appropriate jurisdiction under such circumstances as may merit such relief.

10. Confidentiality. While this Agreement is in effect and for a period of seven years thereafter, you shall hold and keep secret and confidential all trade secrets (within the
meaning of California law) and shall use such information only in the course of performing your duties hereunder; provided, however, that with respect to trade secrets, you shall hold and keep secret and confidential such trade secrets for so long
as they remain trade secrets under California law. You shall maintain in trust all such trade secrets as the Companys property, including, but not limited to, all documents concerning the Companys business, including your work papers,
telephone directories, customer information and notes, and any and all copies thereof in your possession or under your control. Upon the expiration or earlier termination of your employment with the Company, or upon request by the Company, you shall
deliver to the Company all such documents belonging to the Company, including any and all copies in your possession or under your control.
