Dear Mr. Jones:

This letter (the “Agreement”) constitutes the agreement between, EF Hutton, division of Benchmark Investments, LLC (“EF Hutton” or the “Placement Agent”) and Odyssey Marine Exploration, Inc., a company incorporated under the laws of the State of Nevada (the “Company”), pursuant to which the Placement Agent shall serve as the exclusive placement agent for the Company, on a “reasonable best efforts” basis, in connection with the proposed placement (the “Placement”) of shares (the “Shares” or the “Securities”) of thecommon stock, par value $0.0001 per share (“Common Stock”), of the Company. The terms of the Placement and the Securities shall be mutually agreed upon by the Company and the purchasers (each, a “Purchaser” and collectively, the “Purchasers”) and nothing herein constitutes that the Placement Agent would have the power or authority to bind the Company or any Purchaser or an obligation for the Company to issue any Securities or complete the Placement. This Agreement and the documents executed and delivered by the Company and the Purchasers in connection with the Placement, including but not limited to the Purchase Agreement (as defined below), shall be collectively referred to herein as the “Transaction Documents.” The date of the closing of the Placement shall be referred to herein as the “Closing Date.” The Company expressly acknowledges and agrees that the obligations of the Placement Agent hereunder are on a reasonable best efforts basis only and that the execution of this Agreement does not constitute a commitment by the Placement Agent to purchase the Securities and does not ensure the successful placement of the Securities or any portion thereof or the success of the Placement Agent with respect to securing any other financing on behalf of the Company. Following the prior written consent of the Company, the Placement Agent may retain other brokers or dealers to act as sub-Agent or selected-dealers on its behalf in connection with the Placement. The sale of the Securities to any Purchaser will be evidenced by a securities purchase agreement (the “Purchase Agreement”) between the Company and such Purchaser in a form mutually agreed upon by the Company and the Placement Agent. Capitalized terms that are not otherwise defined herein have the meanings given to such terms in the Purchase Agreement. Prior to the signing of any Purchase Agreement, executive officers of the Company will be available upon reasonable notice and during normal business hours to answer inquiries from prospective Purchasers. The Placement Agent acknowledges that it has not provided a copy of the Purchase Agreement, or a draft thereof, to the Company and, accordingly, the Company cannot know with any reasonable degree of certainty the definition of any term not defined herein (an “Undefined Term”). In light of the foregoing, the Company shall not be liable to the Placement Agent for (x) the inaccuracy of any representation or warranty set forth or incorporated by reference herein or (y) the breach or violation of any covenant or agreement set forth or incorporated by reference herein, in each case to the extent that the accuracy of such representation or warranty or the satisfaction or fulfillment of such covenant or agreement is dependent, in whole or in part, upon the actual definition, as set forth in the Purchase Agreement, of such Undefined Term.

SECTION 1. REPRESENTATIONS AND WARRANTIES OF THE COMPANY. Each of the representations and warranties (together with any related disclosure schedules thereto) and covenants made by the Company to the Purchasers in the Purchase Agreement in connection with the Placement is hereby incorporated herein by reference into this Agreement (as though fully restated herein) and is, as of the date of the Purchase Agreement and as of the Closing Date, hereby made to, and in favor of, the Placement Agent.

PERSONAL AND CONFIDENTIAL

EXHIBIT A

INDEMNIFICATION PROVISIONS

January 6^th, 2021

In connection with the engagement of EF Hutton, division of Benchmark Investments, LLC (“EF Hutton” or the “Placement Agent”) by Odyssey Marine Exploration, Inc. (the “Company”) pursuant to a placement agency agreement dated as of the date hereof, by and among the Company and the Placement Agent, as it may be amended from time to time in writing (the “Agreement”), the Company hereby agrees as follows:

1. To the extent permitted by law, the Company will indemnify the Placement Agent and its respective affiliates, directors, officers, employees and controlling persons (within the meaning of Section 15 of the Securities Act of 1933, as amended, or Section 20 of the Securities Exchange Act of 1934) against all losses, claims, damages, expenses and liabilities, as the same are incurred (including the reasonable fees and expenses of counsel), relating to or arising out of its activities hereunder or pursuant to the Agreement, except, with regard to the Placement Agent, to the extent that any losses, claims, damages, expenses or liabilities (or actions in respect thereof) are found in a final judgment (not subject to appeal) by a court of law to have resulted primarily and directly from such Placement Agent’s willful misconduct or gross negligence in performing the services described herein, as the case may be.

2. Promptly after receipt by the Placement Agent of notice of any claim or the commencement of any action or proceeding with respect to which the Placement Agent is entitled to indemnity hereunder, the Placement Agent will notify the Company in writing of such claim or of the commencement of such action or proceeding, and the Company will assume the defense of such action or proceeding and will employ counsel reasonably satisfactory to the Placement Agent and will pay the fees and expenses of such counsel. Notwithstanding the preceding sentence, the Placement Agent will be entitled to employ counsel separate from counsel for the Company and from any other party in such action if counsel for the Placement Agent reasonably determines that it would be inappropriate under the applicable rules of professional responsibility for the same counsel to represent both the Company and the Placement Agent. In such event, the reasonable fees and disbursements of no more than one such separate counsel will be paid by the Company. The Company will have the exclusive right to settle the claim or proceeding provided that the Company will not settle any such claim, action or proceeding without the prior written consent of the Placement Agent, which will not be unreasonably withheld, conditioned, or delayed.

3. The Company agrees to notify the Placement Agent promptly of the assertion against it or any other person of any claim or the commencement of any action or proceeding relating to the Placement and known to the Company.

4. If for any reason the foregoing indemnity is unavailable to the Placement Agent or insufficient to hold the Placement Agent harmless, then the Company shall contribute to the amount paid or payable by the Placement Agent as a result of such losses, claims, damages or liabilities in such proportion as is appropriate to reflect not only the relative benefits received by the Company on the one hand, and the Placement Agent on the other, but also the relative fault of the Company on the one hand and the Placement Agent on the other that resulted in such losses, claims, damages or liabilities, as well as any relevant equitable considerations. The amounts paid or payable by a party in respect of losses, claims, damages and liabilities referred to above shall be deemed to include any legal or other fees and expenses incurred in defending any litigation, proceeding or other action or claim. Notwithstanding the provisions hereof, the Placement Agent’s share of the liability hereunder shall not be in excess of the amount of fees actually received, or to be received, by the Placement Agent under the Agreement (excluding any amounts received as reimbursement of expenses incurred by the Placement Agent).

5. These Indemnification Provisions shall remain in full force and effect whether or not the Placement is completed and shall survive the termination of the Agreement, and shall be in addition to any liability that the Company might otherwise have to any indemnified party under the Agreement or otherwise.
