and in the manner or manners as described in Addendum A, a copy of which is attached hereto and incorporated herein by this reference.
| | -- |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
| |    | 
| | b. |  | All moneys payable hereunder shall be in U.S. funds and drawn on U.S. banks.                                                                                                                                                                                                                                                                                          
| |    | 
| | c. |  | For all special services, not within the scope of this Consulting Agreement, Client shall pay to Consultant such fee(s) as, and when, the parties shall determine in advance of performance of said special services,
provided Client has agreed to said special services.

Consultant shall provide said services as an independent contractor, and not as an employee or of any Client
affiliated with Client. Consultant has no authority to bind Client or any affiliate of Client to any legal action, contract, agreement, or purchase, and such action cannot be construed to be made in good faith or with the acceptance of Client;

amendments are mutually agreed upon by and between the parties hereto and that said modifications or amendments are made in writing and signed by both parties.

16.   Severability

If any provision of this Consulting Agreement shall be held to be contrary to law, invalid or unenforceable for any reason, the remaining provisions shall continue to be valid and enforceable. If a court finds that
any provision of this Consulting Agreement is contrary to law, invalid or unenforceable, and that by limiting such provision it would become valid and enforceable, then such provision shall be deemed to be written, construed, and enforced as so
limited.

17.   Termination of Agreement

This Consulting Agreement may not be terminated by either party prior to the expiration of the term provided
in paragraph 4 above except as follows:

| | a. |  | Upon the bankruptcy or liquidation of the other party; whether voluntary or involuntary;

| |    | 
| | d. |  | Upon the six month anniversary date of this Consulting Agreement provided that no less than 30 days prior written notice of such termination is given after a minimum of three months; and/or
| |    | 
| | e. |  | As provided for in paragraph 19 below.

Agreement, or breach thereof, to binding Commercial Arbitration Rules of the American Arbitration Association of the state of incorporation of the client. Judgment upon the award rendered by the arbitrator(s) shall be final and binding on the
parties and may be entered by either party in any court or forum, state or federal, having jurisdiction. If legal action is taken to enforce this Agreement, the prevailing party shall be entitled to recover reasonable attorney fees, interest, if
applicable, plus arbitration cost for the expense of collection or defense of the action.

19.   Non-waiver

The failure of either party, at any time,
to require any such performance by any other party shall not be construed as a waiver of such right to require such performance, and shall in no way affect such partys right to require such performance and shall in no way affect such
partys right subsequently to require full performance hereunder.

20.   Early Termination

In the event Client fails or refuses to cooperate with
Consultant, or fails or refuses to make timely payment of the compensation set forth above, Consultant shall have the right to terminate any further performance under this Consulting Agreement. In such event, and upon notification thereof, all
compensation shall become immediately due and payable and/or deliverable, and Consultant shall be entitled to receive and retain the same as liquidated damages and not as a penalty, in lieu of all other remedies the parties hereby acknowledge and
agree that it would be too difficult currently to determine the exact extent of Consultants damages, but that the receipt and retention of such compensation is a reasonable present estimate of such damage.

21.   Limitation of Consultant Liability

In the event Consultant fails to perform its work or services hereunder, its entire liability to Client shall not exceed the lessor of; (a)
the amount of cash compensation Consultant has received from Client under paragraph 10 above or (b) the amount of cash, stock and other compensation Consultant has received from Client under Addendum A. In no event shall Consultant be liable to
Client for any indirect, special or consequential damages, nor for any claim against Client by any person or entity arising from or in any way related to this Consulting Agreement.
