NOTE J – RELATED PARTY TRANSACTIONS

On December 9, 2002, a Georgia limited liability company acquired rights from an unrelated third party through a foreclosure sale to receive 5% of post-finance cost proceeds, if any, from shipwrecks that we may recover within a predefined search area of the Mediterranean Sea. The shipwreck we believe to be HMS Sussex is located within this search area. Two of our officers and directors at the time owned a 58% interest in the limited liability company until they sold their interests to an unrelated third party in 2005. If, at any time, Odyssey is forced to cancel or abandon the project due to political interference, the former officers may be required to buy back their interests.

Based on the economic substance of our business transactions with Monaco Financial, LLC, we consider Monaco to be an affiliated company, thus a related party. We do not own any financial interest in Monaco. We had accounts receivable with Monaco and related affiliates at December 31, 2018 of $612,498 and at December 31, 2017 of $183,453. We had general operating payables with Monaco at December 31, 2018 of $233,855 and at December 31, 2017 of $200,801. See NOTE H for further debt arrangements between the entities.
