On April 20, 2018, Odyssey Marine Exploration, Inc. (“Odyssey”) and Monaco Financial, LLC (“Monaco”) entered into a Loan and Security Agreement and First Amendment to Loan Agreement (the “Monaco Loan Agreement”). Pursuant to the Monaco Loan Agreement, Monaco loaned Odyssey $1.0 million and agreed to treat $99,367 of back rent owed by Odyssey to Monaco as a loan from Monaco to Odyssey, resulting in an aggregate principal amount of $1,099,367. The indebtedness is evidenced by a Promissory Note (the “Monaco Note”) and bears interest at a rate equal to 10.0% per annum. The entire outstanding principal amount outstanding under the Monaco Note and all accrued interest thereon are due and payable on April 20, 2019. As security for Odyssey’s obligations under the Monaco Note, Odyssey granted to Monaco a security interest in Odyssey’s right to receive a percentage of the net proceeds from certain shipwreck recovery projects. Pursuant to the Monaco Loan Agreement, Odyssey and Monaco also agreed to extend a notice period under a Loan Agreement entered into by Odyssey and Monaco in August 2014.

Also on April 20, 2018, Odyssey, Aldama Mining Company, S. de R.L. de C.V., an indirect, wholly owned subsidiary of Odyssey (“Aldama”), and SMOM Limited (“SMOM”) entered into an Amended and Restated Loan and Security Agreement (the “Amended SMOM Loan Agreement”), which amended and restated the Loan and Security Agreement that the parties entered into in May 2017. Pursuant to the SLA, SMOM agreed to increase, from $3.0 million to $3.5 million, the amount that may be borrowed by Odyssey thereunder. The indebtedness is evidenced by an Amended and Restated Convertible Promissory Note (the “Amended SMOM Note”) and bears interest at a rate equal to 10.0% per annum. The entire outstanding principal amount outstanding under the Amended SMOM Note and all accrued interest thereon are due and payable on May 3, 2019. As security for Odyssey’s obligations under the Amended SMOM Note, Odyssey granted to Monaco a security interest in (a) 50% of the equity interest held by Odyssey in Aldama and (b) Odyssey’s contractual right to receive right to receive a percentage of the net proceeds from certain shipwreck recovery projects. The holder of the Amended SMOM Note has the option to convert any unpaid principal and interest into up to 50% of the equity interest held by Odyssey in Aldama. The conversion value of $1.0 million equates to 10% of the equity interest in Aldama. If the holder elects to acquire the entire 50.0% of the equity interest, but the amount of principal and interest accumulated to be converted is insufficient to acquire the entire 50% equity interest, the holder has to pay the deficiency in cash. As additional consideration for the loan, the holder has the right to purchase from Odyssey all or a portion of the equity collateral (up to the 50% of the equity interest of Aldama) for the option consideration ($1.0 million for each 10% of equity interests) during the period that is the later of (i) one year after the maturity date and (ii) one year after the loan is repaid in full. The holder may also choose to extend the expiration date annually by paying $500,000 for each year extended.

The foregoing descriptions of the Monaco Loan Agreement, the Monaco Note, the Amended SMOM Loan Agreement, and the Amended SMOM Note are summaries and do not purport to be complete descriptions of all of the terms of such documents and are qualified in their entirety by reference to such documents, which are attached hereto as Exhibits 10.1, 10.2, 10.3, and 10.4, respectively.
