Consultant further understands that if Consultant files a lawsuit for retaliation for reporting a suspected violation of law, Consultant may disclose the Company’s trade secrets to his or her attorney and use the trade secret information in the court proceeding if any document containing the trade secret is filed under seal and Consultant does not disclose the trade secret, except pursuant to court order.

Consultant will not disclose or use any information received by the Company from third parties, except as required in connection with the Services. Consultant will not improperly use or disclose any confidential information or trade secrets of any third party or former employer to whom Consultant has an obligation of confidentiality. Consultant’s performance of all the terms of this Agreement does not breach any agreement by which he or she is legally bound, and Consultant agrees not to become a party to any such agreement.

Inventions shall include, but are not limited to, ideas, concepts, know-how, software, data and database rights. Consultant agrees to promptly disclose to the Company all Inventions and keep accurate records relating to the conception and reduction to practice of all Inventions, which records shall be the sole and exclusive property of the Company. Consultant also hereby assigns to the Company the entire right, title and interest in and to the Inventions and in and to all proprietary rights therein or based thereon including without limitation any and all copyrights, patents, mask work rights or other intellectual property rights relating to all Inventions. Without limiting the foregoing, Consultant agrees that all Inventions which are protectable by copyright and may constitute “works made for hire” pursuant to United States Copyright Act (17 U.S.C., Section 101) shall be deemed to be “works made for hire.” Consultant shall not incorporate any Prior Inventions (as defined below) into any work performed for the Company without the Company’s prior written consent; however, if Consultant does incorporate any such Prior Inventions, the Company is hereby granted a nonexclusive, royalty-free, irrevocable, perpetual, fully-paid, worldwide license (with rights to sublicense) in and to all present and future rights in the same. “Prior Inventions” means any work or inventions made by Consultant prior to the commencement of the Consultant’s engagement with the Company hereunder, which are owned in whole or in part by the Consultant.

This restriction includes any customer to which the Company sold any product, or for which the Company performed any service at any time during the one year period immediately before the date this Agreement terminated.

(b) Non-Competition. In view of Consultant’s access to the Company’s confidential or proprietary information, trade secrets and other proprietary know-how and in order to protect the same, Consultant agrees that during the Restricted Period Consultant will not, without the Company’s prior written approval, provide services (whether as an employee, consultant, proprietor, stockholder, partner, director or otherwise) to any person or entity which has or is developing products or services which compete or can reasonably be anticipated to compete, either directly or indirectly, with the products or services then offered or reasonably anticipated to be offered by the Company anywhere in which the Company is currently, or was during the immediately preceding twelve (12) month period, engaged in active business. Notwithstanding the foregoing, this engagement is not exclusive and Consultant shall be permitted to engage in other businesses which are not competitive with the Company, on Consultant’s own time, provided Consultant does not breach this Agreement (in particular Sections 6 and 8(a) hereof) and such business is conducted without the use of Company resources or facilities.

(c) Non-Disparagement. Consultant agrees not to make any disclosures, issue any statements or otherwise cause to be disclosed any information which is designed, intended or might reasonably be anticipated to disparage the Company, its officers, directors or employees, or its business, services or products.

9. REPRESENTATION AND WARRANTY AND SURVIVAL. Consultant warrants that everything delivered to the Company under this Agreement shall be original work and that all such materials will not violate any copyright, trade secret or other proprietary right of any third party. Any provision of this Agreement which by its terms imposes continuing obligations on either of the parties shall survive termination of this Agreement.

10. WAIVER. Failure to insist upon strict compliance with any of the terms, covenants or conditions hereof shall not be deemed a waiver of such terms, covenants or conditions, nor shall any waiver or relinquishment of any right or power granted hereunder at any particular time be deemed a waiver or relinquishment of such rights or power at any other time or times.

11. INDEPENDENT CONTRACTOR STATUS; TAX MATTERS.

(a) Nothing contained in this Agreement shall be deemed or construed as creating a joint venture or partnership between Consultant and the Company. Neither party is by virtue of this Agreement authorized as an agent, employee or legal representative of the other. Except as specifically set forth herein, neither party shall have the power to control the activities and operations of the other and its status at all times will continue to be that of an independent contractor. Except as provided herein, neither party shall have any power or authority to bind or commit the other. Consultant shall pay all taxes of any kind whatsoever which arise from the compensation paid to Consultant hereunder and shall indemnify and hold the Company harmless from failure to pay such taxes.

(b) This Agreement is intended to comply with the requirements of Section 409A of the Internal Revenue Code of 1986, as amended, and the Treasury Regulations and other applicable guidance thereunder (“Section 409A”). To the extent that there is any ambiguity as to whether this Agreement (or any of its provisions) contravenes one or more requirements of Section 409A, such provision shall be interpreted and applied in a matter that does not result in a Section 409A violation. Without limiting the generality of the above:

(i) The payments of the Termination Fee shall be deemed to be a series of separate payments, with each installment being treated as a separate payment. The time and form of payment of any compensation may not be deferred or accelerated to the extent it would result in an impermissible acceleration or deferral under Section 409A.

(ii) To the extent this Agreement contains payments which are subject to Section 409A (as opposed to exempt from Section 409A), the Consultant’s rights to such payments are not subject to anticipation, alienation, sale, transfer, pledge, encumbrance, attachment or garnishment and, where applicable, may only be transferred by will or the laws of descent and distribution.

(iii) If the Termination Fee becomes payable, it shall be paid or provided in full no later than December 31st of the second calendar year following the calendar year in which the Agreement was terminated unless another time period is applicable.

(iv) The Company makes no representation that this Agreement will be exempt from or compliant with Section 409A and makes no affirmative undertaking to preclude Section 409A from applying, but does reserve the right to unilaterally amend this Agreement as may be necessary or advisable to permit the Agreement to be in documentary and operational compliance with Section 409A which determination will be made in the sole discretion of the Company.

12. SEVERABILITY. The invalidity or unenforceability of any provision hereof shall in no way affect the validity or enforceability of any other provision.

13. ENTIRE AGREEMENT; MODIFICATION. The Agreement embodies the entire agreement between the Company and Consultant relating to the subject matter hereof and supersedes all prior understandings or agreements between the parties with regard to its subject matter, including the Prior Agreement. This Agreement may be changed, modified or discharged only if consented to in writing by both parties.

14. GOVERNING LAW. This Agreement shall be governed by and according to the laws of the State of Florida without regard to its conflicts of law rules.

15. BENEFIT. This Agreement shall be binding upon and shall inure to the benefit of each of the parties hereto, and to their respective heirs, representatives, successors and assigns.
