6. Confidentiality. The Executive
promises that she will receive, develop and hold Confidential Information (as defined below) in strict confidence and will not use or disclose Confidential Information, or make copies of any documents containing Confidential Information, except in
furtherance of the Business of the Company, unless the Chief Executive Officer provides prior written consent. The Executive further agrees to use reasonable efforts to safeguard the Confidential Information and protect it from disclosure, misuse,
loss or theft. The foregoing



4



---

promises of confidentiality shall not apply if and to the extent that the Executive is ordered by a court or other governmental agency to disclose
Confidential Information, provided the Executive has given the Company prompt written notice of the order or subpoena and provides all reasonable cooperation necessary to limit such disclosure and to protect the confidentiality of any Confidential
Information so disclosed. Confidential Information means all nonpublic information (whether or not specifically labeled or identified as confidential), that has been or is disclosed to, developed or learned by the Executive as a result
of employment with the Company and that relates to the business, finances, products, services, customers, research or development of the Company or third parties with whom the Company does business or from whom the Company receives information. The
definition of Confidential Information includes, but is not limited to, the following: access codes, security devices and naming conventions used in software and hardware systems; databases of information; other proprietary software; proprietary
specifications for hardware and software platforms, the identity and transactions with customers, clients and suppliers; marketing product and service plans, objectives and strategies; tactical objectives, approaches, and competitive advantages;
internal financial information; specialized marketing programs related to products and services offered or under development by the Company (or any parent or affiliate of the Company); data and reports related to marketing programs; proprietary
systems and operations manuals; proprietary training manuals; proprietary technical and scientific know-how, data and strategies; the Companys information gathering processes and compilations of information; and information disclosed to the
Company by its business partners, licensees, customers and clients in reliance on promises that its confidentiality will be preserved.

7.
Non-Solicitation.

(a) The Executive recognizes that the Company incurs significant expense in training employees to provide
services in accordance with the Companys Business and that the Company will disclose Confidential Information to each such employee. The Executive promises that, during the Agreement Term and for a period of 18 months after expiration of the
Agreement Term, the Executive will not, without the prior written consent of the Company, knowingly hire, directly or indirectly, any person then employed by the Company, or knowingly solicit, directly or indirectly, such a person either to
terminate or diminish employment with the Company, or to work for any other person or entity, whether or not a competitor, and the Executive shall not approach any such employee for any such purpose or authorize or knowingly cooperate with the
taking of any such actions by any other individual or entity.

(b) The Executive also acknowledges that the Company incurs significant
expense in developing business partners, licensees, customers and clients. The Executive promises that, during the Agreement Term and for a period of 18 months after the Agreement Term ends, the Executive will not, without the prior written consent
of the Company, knowingly directly or indirectly, solicit any customer, business partner, licensee or client of the Company to terminate or diminish its business relationship with the Company or to purchase any product or service that is or may be
used as a substitute for any product or service of the Company, and the Executive shall not knowingly approach any such customer, supplier, lessor or lessee for such purpose or authorize or knowingly cooperate with the taking of any such actions by
any other individual or entity.

8. Restrictions Reasonable. Executive agrees that the restrictions set forth in sections 5
(Non-Competition), 6 (Confidentiality), and 7 (Non-Solicitation) are reasonable, proper and necessitated by the legitimate business interests of the Company, and do not constitute an unlawful or unreasonable restraint upon Executives ability
to earn a living. Executive acknowledges that it may be impossible to assess the monetary damages occurred by Executives violation of sections 6, 7 or 8 of this Agreement, that violations of those sections will be material breaches of this
Agreement and will cause irreparable injury to the Company. Accordingly, Executive agrees that Company will be entitled, in addition to all other rights and remedies which may be available, to an injunction in joining and restraining Executive and
any other involved party from committing a violation of this Agreement, and Executive consents to the issuance and entry of such injunction. In addition, Company will be entitled to such damages as it can demonstrate that it sustained by reason of
the violation of this Agreement by the Executive and/or others. The parties agree that in the event of any litigation to enforce or interpret this Agreement, the prevailing party will be entitled to recover all costs, including reasonable
attorneys fees, from the non-prevailing party. In the event Company enforces this section through a Court Order, Executive agrees that the restriction on Executive following termination of employment set forth in this Agreement shall remain in
effect for a period of one year from the date of the final Court Order enforcing this Agreement.

9. Return of Materials. Upon the
Executives Date of Termination, or at any time upon the Companys request, the Executive (or if deceased, the Executives personal representative) shall promptly deliver to the Company without retaining copies, all tangible things
that are or contain Confidential Information. The Executive or such personal representative shall also promptly deliver to the Company all computer print-outs, books, software manuals and directions, floppy disks and other such media for storing
software and information, work papers, files, customer lists, supplier lists, employee lists, telephone and/or address books, Rolodex or equivalent cards, memoranda, appointment books, calendars, employee manuals, sales aides, keys and other
tangible things provided to the Executive by the Company, or authored in whole or in part by the Executive within the scope of her employment by the Company, even if they do not contain Confidential Information; provided that the Executive
shall not be required to deliver personal files and personal information unrelated to the Companys business. At the time of such deliveries, the Executive shall disclose to the Company any passwords or other knowledge required to access and
use any of the foregoing. The Executive acknowledges that she does not have, and will not acquire, any ownership rights in such materials and things.

10. Nonalienation. The interests of the Executive under this Agreement are not subject in any manner to anticipation, alienation, sale, transfer, assignment, pledge, encumbrance, attachment, or garnishment by
the Executives creditors or beneficiaries.

11. Successors. This Agreement shall be binding upon, and inure to the benefit of,
the Company and its successors and assigns and upon any person acquiring, whether by merger, consolidation, purchase of assets or otherwise, all or substantially all of the Companys assets and business.

12. Notices. Notices and all other communications provided for in this Agreement shall be in writing and shall be delivered personally or sent by
