discovers, validates and develops high value seafloor resources in an environmentally responsible manner, providing access to critical resources that can transform societies and economies for generations to come. </P>
<P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:9%; font-size:10pt; font-family:Times New Roman">The company has a diversified mineral portfolio that includes projects controlled by us and other projects in which we are a minority owner
and service provider. In addition, our team is continually working to add new projects to the portfolio by identifying potential new assets through a proprietary Global Prospectivity Program leading to the acquisition of appropriate rights. </P>
<P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:9%; font-size:10pt; font-family:Times New Roman">Our development focus is&nbsp;on projects that can meet stringent standards for environmental responsibility and sustainability while
unlocking benefits for the host country. Environmental protection remains at the forefront of the strategic and tactical decision-making processes in all our work.</P>
<P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:9%; font-size:10pt; font-family:Times New Roman">Each project in the portfolio is advanced along a defined development path, decreasing risk and increasing value along the way. These steps
may include, but are not limited to, verification and quantification of the mineral asset, collection of baseline environmental data essential for environmental permitting, environmental impact studies and reports, design and verification of
extraction systems and definition and verification of commercial programs. Odyssey may elect to sell equity in individual projects to fund continued advancement of the project. </P>
<P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:9%; font-size:10pt; font-family:Times New Roman">For nearly 30 years, we have been deploying cutting-edge ocean technology and processes at depths up to 6,000 meters, under the direction of
some of the industry&#146;s most skilled and successful ocean exploration professionals, scientists, and environmental specialists. </P> <P STYLE="margin-top:18pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman"><B>Importance of
Seabed Mineral Exploration </B></P> <P STYLE="margin-top:6pt; margin-bottom:0pt; text-indent:9%; font-size:10pt; font-family:Times New Roman">There is growing global demand for critical mineral resources to power the green economy, feed the
world&#146;s growing population and provide vital infrastructure.&nbsp;Land based deposits of cobalt, manganese, rare earth minerals, phosphorite, gold, silver, copper and zinc&nbsp;are being depleted.</P>
<P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:9%; font-size:10pt; font-family:Times New Roman">As the worldwide population continues to grow, it is necessary to explore additional and alternative sources of these much-needed materials.
</P> <P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:9%; font-size:10pt; font-family:Times New Roman">Subsea mineral deposits can provide these critical resources with less social and environmental impact. We have the expertise and
technology to find and access these deposits and to prepare the project for extraction in an economically feasible and environmentally sensitive way. </P>

fields within the area are adjacent to the terrestrial Ladolam Gold Mine and are believed to have originated from the same volcanogenic source. The resource lies <FONT STYLE="white-space:nowrap">500-2,000</FONT> meters deep in the Papua New Guinea
Exclusive Economic Zone off the coast of Lihir Island, adjacent the location of one of the world&#146;s largest know terrestrial gold deposits. </P>

evaluating options to mine deep-ocean mineralized materials. As our mineral exploration business plan includes partnering with others in the industry, we view these entities as potential partners rather than pure competitors. As mineral rights are
generally granted on an exclusive basis for a specific area or tenement, once licenses are granted, we do not anticipate any competitive intrusion on those areas. It is possible that one of these companies or some currently unknown group may secure
licenses on an area desired by us or one of our partners; but since exploration work does not start until licenses are secured, we do not believe that competition from one or more of these entities, known or unknown, would materially affect our
operating plan or alter our current business strategy. For offshore mineral exploration, there are providers of vessels and equipment that could be competitors or partners for certain projects. These companies generally service the oil, gas and
telecom industries with survey capabilities. We view these companies as potential strategic partners or services providers for our projects. </P> <P STYLE="margin-top:18pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman"><B>Cost of

evaluating Odyssey or any investment decision relating to our securities. This section is intended only as a summary of the principal risks. If any of the following risks actually occur, our business, financial condition, or operating results could
suffer. If this occurs, the trading price of our common stock could decline, and you could lose all or part of the money you paid to buy our common stock. </I></P>

<P STYLE="margin-top:6pt; margin-bottom:0pt; text-indent:9%; font-size:10pt; font-family:Times New Roman">An investment in Odyssey is extremely speculative and of exceptionally high risk. With respect to mineral exploration projects, there are
uncertainties with respect to the quality and quantity of the material and their economic feasibility, the price we can obtain for the sale of the deposit or the ore extracted from the deposit, the granting of the necessary permits to operate,
environmental safety, technology for extraction and processing, distribution of the eventual ore product, and funding of necessary equipment and facilities. In projects where Odyssey takes a minority ownership position in the company holding the
mining rights, there may be uncertainty as to that company&#146;s ability to move the project forward. </P> <P STYLE="margin-top:18pt; margin-bottom:0pt; margin-left:9%; font-size:10pt; font-family:Times New Roman"><B><I>The research and data we use

contracting party have obtained. By its very nature, research and data regarding mineral deposits can be imprecise, incomplete, outdated, and unreliable. For mineral exploration, data is collected based on a sampling technique and available data may
not be representative of the entire ore body or tenement area. Prior to conducting <FONT STYLE="white-space:nowrap">off-shore</FONT> exploration, we typically conduct <FONT STYLE="white-space:nowrap">on-shore</FONT> research. There is no guarantee
that the models and research conducted onshore will be representative of actual results on the seafloor. Offshore exploration typically requires significant expenditures, with no guarantee that the results will be useful or financially rewarding.

sampling or extractions operations during favorable periods. In addition, even though sea conditions in a particular search location may be somewhat predictable, the possibility exists that unexpected conditions may occur that adversely affect our
operations. It is also possible that natural hazards may prevent or significantly delay operations. Seabed mineral extraction work may be subject to interruptions resulting from storms that adversely affect the extraction operations or the ports of

of a contracting party, we may be subjected to unexpected delays, requests, and outcomes as it works with local governments to define and obtain the necessary permits and to assert its claims over assets on the seafloor bottom. Our vessel,
equipment, personnel and or cargo could be seized or detained by government authorities. We may have to work with different units of a government, and there may be a change of government representatives over time. This may result in unexpected

</I></B></P> <P STYLE="margin-top:6pt; margin-bottom:0pt; text-indent:9%; font-size:10pt; font-family:Times New Roman">We have invested in marine mineral companies that to date are still in the exploration phase and have not begun to earn revenue
from operations. We may or may not have control or input on the future development of these businesses. There can be no assurance that these companies will achieve profitability or otherwise be successful in capitalizing on the mineralized materials
they intend to exploit. </P> <P STYLE="margin-top:18pt; margin-bottom:0pt; margin-left:9%; font-size:10pt; font-family:Times New Roman"><B><I>We may be subject to short selling strategies. </I></B></P>
<P STYLE="margin-top:6pt; margin-bottom:0pt; text-indent:9%; font-size:10pt; font-family:Times New Roman">Short sellers of our stock may be manipulative and may attempt to drive down the market price of our common stock. Short selling is the
practice of selling securities that the seller does not own but rather has, supposedly, borrowed from a third party with the intention of buying identical securities back at a later date to return to the lender. The short seller hopes to profit from
a decline in the value of the securities between the sale of the borrowed securities and the purchase of the replacement shares, as the short seller expects to pay less in that purchase than it received in the sale. As it is therefore in the short
seller&#146;s best interests for the price of the stock to decline, many short sellers (sometime known as &#147;disclosed shorts&#148;) publish, or arrange for the publication of, negative opinions regarding the relevant issuer and its business
prospects to create negative market momentum and generate profits for themselves after selling a stock short. Although traditionally these disclosed shorts were limited in their ability to access mainstream business media or to otherwise create
negative market rumors, the rise of the Internet and technological advancements regarding document creation, videotaping and publication by weblog (&#147;blogging&#148;) have allowed many disclosed shorts to publicly attack a company&#146;s
credibility, strategy and veracity by means of <FONT STYLE="white-space:nowrap">so-called</FONT> &#147;research reports&#148; that mimic the type of investment analysis performed by large Wall Street firms and independent research analysts. These
short attacks have, in the past, led to selling of shares in the market, on occasion in large scale and broad base. Issuers who have limited trading volumes and are susceptible to higher volatility levels than
<FONT STYLE="white-space:nowrap">large-cap</FONT> stocks, can be particularly vulnerable to such short seller attacks. These short seller publications are not regulated by any governmental, self-regulatory organization or other official authority in
the U.S., are not subject to certification requirements imposed by the Securities and Exchange Commission and, accordingly, the opinions they express may be based on distortions or omissions of actual facts or, in some cases, fabrications of facts.
In light of the limited risks involved in publishing such information, and the enormous profit that can be made from running just one successful short attack, unless the short sellers become subject to significant penalties, it is more likely than
not that disclosed short sellers will continue to issue such reports. </P> <P STYLE="margin-top:18pt; margin-bottom:0pt; margin-left:9%; font-size:10pt; font-family:Times New Roman"><B><I>Some of our equipment or assets could be seized or we may be

our loan agreements. Some suppliers have the ability to seize some of our assets if we do not make timely payments for the services, supplies, or equipment that they have provided to us. If we were unable to make payments on these obligations, the
lender or supplier may seize the asset or force the sale of the asset. The loss of such assets could adversely affect our operations. The sale of the asset may be done in a manner and under circumstances that do not provide the highest cash value
for the sale of the asset. </P> <P STYLE="margin-top:18pt; margin-bottom:0pt; margin-left:9%; font-size:10pt; font-family:Times New Roman"><B><I>We could be delisted from the NASDAQ Capital Market. </I></B></P>

price for our common stock must remain at or above $1.00 per share to comply with NASDAQ&#146;s minimum bid requirement for continued listing. If the closing bid price for our common stock is less than $1.00 per share for 30 consecutive business
days, NASDAQ may send us a notice stating we will be provided a period of 180 days to regain compliance with the minimum bid requirement or else NASDAQ may make a determination to delist our common stock. Another requirement for continued listing on

compliance with the above-mentioned and other NASDAQ continued listing requirements may lead to the delisting of the company from the NASDAQ Capital Market. Delisting from the NASDAQ Capital Market could make trading our common stock more difficult
for investors, potentially leading to declines in our share price and liquidity. If our common stock is delisted by NASDAQ, our common stock may be eligible to trade on an
<FONT STYLE="white-space:nowrap"><FONT STYLE="white-space:nowrap">over-the-counter</FONT></FONT> quotation system, where an investor may find it more difficult to sell our stock or obtain accurate quotations as to the market value of our common

obtain War Risk coverage for a project at a specific date and location, such insurance may be unavailable at other times and locations. Although we may be able to insure our marine assets for certain risks such as certain possible loss or damage

our customers and related parties. Total revenue decreased by $1.0&nbsp;million in 2020 as compared to 2019. The $1.0&nbsp;million decrease is comprised of a $1.4&nbsp;million reduction resulting from the long-term project we were engaged on since
2018 having reached its life expectancy during this period offset in part by an increase of $0.4&nbsp;million increase in marine exploration services. </P>
<P STYLE="margin-top:18pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman"><B>Cost and Expenses </B></P> <P STYLE="margin-top:6pt; margin-bottom:0pt; text-indent:9%; font-size:10pt; font-family:Times New Roman">Marketing, general and
administrative expenses primarily include all costs within the following departments: Executive, Finance&nbsp;&amp; Accounting, Legal, Information Technology, Human Resources, Marketing&nbsp;&amp; Communications, Sales and Business Development.
Marketing, general and administrative expense decreased $1.7&nbsp;million to $3.6&nbsp;million in 2020 compared to $5.5&nbsp;million in 2019. The key items contributing to this $1.7&nbsp;million decrease was
<FONT STYLE="white-space:nowrap">a&nbsp;non-cash&nbsp;decrease</FONT> of share-based compensation of $0.2&nbsp;million and a net reduction of $1.2 in employee incentives and employee and director related compensation. The $1.2&nbsp;million reduction
was primarily due to the reduction of the discretionary incentive reserve resulting from management&#146;s decision to not pay discretionary incentives until appropriate. We also had a $0.4&nbsp;million reduction in professional corporate services
which includes a reduction of approximately $0.3&nbsp;million in maritime legal services associated with the HMS<I>&nbsp;Victory</I>&nbsp;as well as fees related to legal and in our annual audit function. These decreases were offset in part by a
$0.1&nbsp;million increase split between governmental fees and our corporate liability insurance. </P>

from 2019 to 2020 primarily as a result of the following items: (i)&nbsp;a $4.3&nbsp;million increase in financed professional fees, legal fees, and other expenses directly associated with our NAFTA litigation pursuit, (ii)&nbsp;a $1.3&nbsp;million
decrease in marine services operating technical labor costs, (iii)&nbsp;a $0.4&nbsp;million increase in our concession permit fees for our Mexican subsidiary and (iv)&nbsp;a $0.4&nbsp;million decrease in our general operational overhead which

$3.3&nbsp;million. This variance was primarily attributable to an increase in interest expense of $3.5&nbsp;million primarily from our litigation financing agreement (NOTE H), a reduction in debt discount accretion in the amount of
$1.0&nbsp;million, a $0.4&nbsp;million incremental expense due to the fair value accounting of our hybrid debt instrument (NOTE H), the prior year included an expense of $0.9&nbsp;million related to the fair value accounting for a warrant inducement
related to debt refinancing, a $0.5&nbsp;million current year expense related to debt extinguishment accounting related to a loan extension, and $0.8&nbsp;million of other income in 2019 attributable to the extinguishment of deferred revenue that
was caused by the 2019 cancelation of the HMS<I>&nbsp;Sussex</I>&nbsp;contract. </P> <P STYLE="margin-top:18pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman"><B>Income Taxes and

corresponding to the equity of Oceanica not owned by us is subsequently shown as the <FONT STYLE="white-space:nowrap">&#147;Non-Controlling</FONT> Interest&#148; in the consolidated statements of operations. The
<FONT STYLE="white-space:nowrap">non-controlling</FONT> interest adjustment for 2020 was $6.3&nbsp;million as compared to $5.1&nbsp;million for 2019. The administrative support has been ongoing in support of the legal process in obtaining the
environmental application for our Mexican subsidiary. This increase was mainly attributable to the compounding debt interest on our Mexican subsidiary&#146;s balance sheet. </P>

our NAFTA litigation financing and funds received from the 37 North agreement (NOTE H). We also participated and received funds from the Small Business Administration (SBA) programs for the Payroll Protection Program (PPP) and the Emergency Injury
Disaster Loan (EIDL) (NOTE H). These debt proceeds of $3.6&nbsp;million were offset by $0.2&nbsp;million of repayments of financed obligations. In August 2020 we sold 2.5&nbsp;million of our common shares
<FONT STYLE="white-space:nowrap">for&nbsp;net-proceeds&nbsp;of</FONT> $11.3&nbsp;million (see NOTE L). During December 2020, we sold $800,000 of new equity in one of our controlled subsidiaries to an existing shareholder of that subsidiary. </P>

payable to SMOM by $0.5 and received $0.8&nbsp;million toward our last promissory note. We also received a net advance of $1.0&nbsp;million from Monaco in January 2018 which was eventually converted to a promissory note. This cash inflow was
partially offset by repayment of debt obligations of $0.2&nbsp;million. During the fourth quarter of 2018, we issued new equity in an equity offering netting the Company $4.6&nbsp;million. </P>

from 37North, the NAFTA litigation financing and the SBA&#146;s programs for the PPP and EIDL as well as the August 2020 capital raise of $11.3&nbsp;million noted below. The $9.3&nbsp;million of cash used from operations was partially offset <FONT

2018, notwithstanding that the Superior Court of the Federal Court of Administrative Justice (TFJA) in Mexico nullified SEMARNAT&#146;s initial denial, we continue to support the efforts of our subsidiaries and partners to work through the
administrative, legal and political process necessary to have the decision reviewed and overturned in the court of the TFJA. On January&nbsp;4, 2019, we initiated the process to submit a claim against Mexico to arbitration under the investment
protection chapter of the North American Free Trade Agreement (NAFTA). On September&nbsp;4, 2020, we filed our First Memorial with the Tribunal. The First Memorial is the filing that fully lays out our case, witnesses and evidence for the Tribunal.
We continue to work diligently and in good faith with Mexico&#146;s current administration to achieve an equitable resolution of this dispute, but we are prepared to proceed with the full NAFTA arbitration process if necessary, see ITEM 1. BUSINESS
OVERVIEW for further detail. </P>

general and administrative expenses decreased $0.2&nbsp;million from $5.7&nbsp;million in 2018 to $5.5&nbsp;million in 2019. This net decrease of $0.2&nbsp;million was primarily due to (i)&nbsp;a net decrease of $0.8&nbsp;million in personnel
expenses attributable to regular, incentive and share-based compensation, (ii)&nbsp;an increase of $0.9&nbsp;million of director compensation at the corporate and subsidiary level (the corporate directors did not receive any cash compensation in
2018), (iii) a $0.1&nbsp;million decrease in corporate legal support and professional services and (iv)&nbsp;a $0.2&nbsp;million allocated reduction of corporate overhead support. </P>

$4.2&nbsp;million was primarily due to (i)&nbsp;a $3.7&nbsp;million increase in legal related support of our NAFTA arbitration with the government of Mexico to assure the fair treatment of our foreign investment, see ITEM 1: BUSINESS for more
information, (ii)&nbsp;reductions of $0.1&nbsp;million and $0.3&nbsp;million in operational support services and depreciation, respectively, and (iii)&nbsp;a $0.9&nbsp;million gain on sale of marine equipment that occurred in 2018, but not in 2019.

income and expense was $5.2 and $3.0&nbsp;million in net expenses for 2019 and 2018, respectively, resulting in a net expense increase of $2.1&nbsp;million. This variance was primarily attributable to an increase in interest expense of
$0.8&nbsp;million from the beneficial conversion feature tied to a promissory note, a warrant inducement of $0.9&nbsp;million, a debt extinguishment loss of $0.3&nbsp;million from a debt modification, new 2019 interest of $0.6&nbsp;million, a fair
valuation loss of $0.3&nbsp;million on new debt assumed during the three months ended December&nbsp;31, 2019, and an increase of other income of $0.8&nbsp;million, which related to the reclassification of our Revenue Participation Rights for our

<P STYLE="margin-top:6pt; margin-bottom:0pt; text-indent:9%; font-size:10pt; font-family:Times New Roman">Net cash used by operating activities in 2019 was $5.4&nbsp;million, an increase of $1.0&nbsp;million compared to the same period in 2018. Net
cash used by operating activities reflected a net loss before <FONT STYLE="white-space:nowrap">non-controlling</FONT> interest of $(15.5) million offset in part by <FONT STYLE="white-space:nowrap">non-cash</FONT> items of $1.7&nbsp;million, which
primarily included depreciation and amortization of $0.1&nbsp;million, note payable interest accretion of $0.8&nbsp;million, equity based compensation of $0.8&nbsp;million and deferred income amortization of $(0.8) million as well as a noncash use
of $(0.7) million for an investment in an unconsolidated entity, loss on debt extinguishment of $0.3&nbsp;million, a loss of $0.3&nbsp;million on the debt fair value option and a $0.9&nbsp;million loss due to a debt modification inducement. Other
operating activities resulted in an increase in working capital of $8.4&nbsp;million. Changes to accrued expenses, accounts receivable, accounts payable and other assets in 2019 comprised the $8.4&nbsp;million. </P>
<P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:9%; font-size:10pt; font-family:Times New Roman">Cash flows used by investing activities for 2019 were $0.01&nbsp;million compared to $1.0&nbsp;million provided by for in 2018. The same
period during 2018 includes a payment of $1.0&nbsp;million from Magellan for the purchase of certain marine assets. </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:9%; font-size:10pt; font-family:Times New Roman">Cash flows provided
by financing activities for 2019 were $2.9&nbsp;million, which represented $2.8&nbsp;million of funds received from our NAFTA litigation financing, and $0.5&nbsp;million debt financing offset by $0.3&nbsp;million of repayments of financed
obligations. For the same period in 2018, we borrowed the final tranche of $0.4&nbsp;million from MINOSA, increased our note payable to SMOM by $0.5 and received $0.8&nbsp;million toward our last promissory note. We also received a net advance of
$1.0&nbsp;million from Monaco in January 2018 which was eventually converted to a promissory note. This cash inflow was partially offset by repayment of debt obligations of $0.2&nbsp;million. During the fourth quarter of 2018, we issued new equity
in an equity offering netting the Company $4.6&nbsp;million. </P> <P STYLE="margin-top:18pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman"><B>General Discussion 2019 </B></P>
<P STYLE="margin-top:6pt; margin-bottom:0pt; text-indent:9%; font-size:10pt; font-family:Times New Roman">At December&nbsp;31, 2019, we had cash and cash equivalents of $0.2&nbsp;million, a decrease of $2.6&nbsp;million from the December&nbsp;31,
2018 balance of $2.8&nbsp;million. This decrease was mainly attributable to the $5.4&nbsp;million used for operations offset in part by $3.3&nbsp;million of financing attributable to the $2.8&nbsp;million received for the NAFTA arbitration
litigation and $0.5&nbsp;million received from new indebtedness. </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:9%; font-size:10pt; font-family:Times New Roman">Financial debt of the company, excluding the derivative or beneficial
conversion feature components of such debt, increased by $3.5&nbsp;million in 2019, from a balance of $30.4&nbsp;million at December&nbsp;31, 2018 to a balance of $33.9&nbsp;million at December&nbsp;31, 2019. This increase was due to the NAFTA
litigation financing of $3.0&nbsp;million and the first tranche of the 37North funding of $0.5&nbsp;million, both of which are discussed above in the Discussion of Cash Flows (see NOTE H). </P>
<P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:9%; font-size:10pt; font-family:Times New Roman">Since SEMARNAT initially declined to approve the environmental permit application of our Mexican subsidiary in April 2016 and again in October
2018, notwithstanding that the Superior Court of the Federal Court of Administrative Justice in Mexico nullified SEMARNAT&#146;s initial denial, we continue to support the efforts of our subsidiaries and partners to work through the administrative,
legal and political process necessary to have the decision reviewed and overturned. </P>

contractual provisions that would limit the useful life of the asset. The exploration license is not dependent on another asset or group of assets that could potentially limit the useful life of the exploration license. In the future, the
recoverability of the license will be tested whenever circumstances indicate that its carrying amount may not be recoverable per the guidance of ASU 360, &#147;<I>Subsequent Measurement&#148;.</I> </P>

<P STYLE="margin-top:6pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman">We have audited the accompanying consolidated balance sheets of Odyssey Marine Exploration, Inc and Subsidiaries (the Company) as of December&nbsp;31, 2020 and

notes (collectively referred to as the consolidated financial statements). In our opinion, the consolidated financial statements present fairly, in all material respects, the financial position of the Company as of December&nbsp;31, 2020 and 2019,
and the results of its operations and its cash flows for each of the years in the <FONT STYLE="white-space:nowrap">two-year</FONT> periods ended December&nbsp;31, 2020, and 2019, in conformity with accounting principles generally accepted in the

<P STYLE="margin-top:6pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman">The accompanying consolidated financial statements have been prepared assuming that the Company will continue as a going concern. As discussed in Note O to the
consolidated financial statements, the Company has incurred significant losses and they may be unsuccessful in raising the necessary capital to fund operations and capital expenditures. These conditions raise substantial doubt about the
Company&#146;s ability to continue as a going concern. Management&#146;s plans regarding those matters are also described in Note O. The consolidated financial statements do not include any adjustments that might result from the outcome of this
uncertainty. </P> <P STYLE="margin-top:18pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman"><B>Basis for Opinion </B></P> <P STYLE="margin-top:6pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman">These consolidated
financial statements are the responsibility of the Company&#146;s management. Our responsibility is to express an opinion on the Company&#146;s consolidated financial statements based on our audits. We are a public accounting firm registered with
the Public Company Accounting Oversight Board (United States) (PCAOB) and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and
Exchange Commission and the PCAOB. </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman">We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and
perform the audits to obtain reasonable assurance about whether the consolidated financial statements are free of material misstatement, whether due to error or fraud. The Company is not required to have, nor were we engaged to perform, an audit of
its internal control over financial reporting. As part of our audits, we are required to obtain an understanding of internal control over financial reporting, but not for the purpose of expressing an opinion on the effectiveness of the
Company&#146;s internal control over financial reporting. Accordingly, we express no such opinion. </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman">Our audits included performing procedures to assess
the risks of material misstatement of the consolidated financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts
and disclosures in the consolidated financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the consolidated financial
statements. We believe that our audits provide a reasonable basis for our opinion. </P>

<P STYLE="margin-top:6pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman">As discussed in Notes A, and F to the consolidated financial statements, the Company recorded an indefinite life intangible exploration license for
approximately $1.8&nbsp;million on the consolidated balance sheets at December&nbsp;31, 2020 and 2019. The Company has determined that the exploration license has an indefinite useful life. This determination is reviewed annually by management, as
well as an annual review for impairment. We identified the assessment of the useful life and potential impairment of the exploration license as a critical audit matter due to the assessment involving judgment in determining whether the rights to the
license have an indefinite life, and judgment in determining if any triggering events have occurred that would cause the exploration license to be impaired. </P>

in Derivative Liabilities Fair Value&#148; of approximately $733,000 and $323,000 for the years ended December&nbsp;31, 2020 and 2019. During the year ended December&nbsp;31, 2020, convertible debt associated with the derivative liability converted
into common stock, and the Company recorded approximately $2.2&nbsp;million in the consolidated statements of changes in stockholders&#146; equity (deficit) under the caption &#147;common stock issued for conversion and settlement of convertible
debt and accounts payable&#148; upon the extinguishment of the derivative liability. The Company utilized a Monte Carlo model to value the derivative liability, which estimates the fair value of the liability based upon certain assumptions utilizing
a probability weighted analysis, and considers the present value of cash flows using a credit risk adjusted rate or discount factor. Other inputs into the model include, volatility, closing stock prices at various valuation points, and conversion
prices as determined by the applicable agreements. We identified the fair value of the derivative liability as a critical audit matter, as the assumptions utilized in the model to value the derivative liability required judgement, and the model is
inherently complex. Additionally, the accounting for derivative liabilities is complex. </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman">The primary procedures we performed to address this critical

<P STYLE="margin-top:6pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman">As discussed in Note H to the consolidated financial statements, the Company had certain convertible promissory notes that were issued with detachable
warrants. The carrying value of the notes is included in &#147;loans payable&#148; on the consolidated balance sheet at December&nbsp;31, 2020 and 2019. During the 2019 and 2020, the Company modified these convertible promissory notes, which
included an extension of the maturity date and a reduction of the conversion price, in addition, the Company issued common stock warrants as an inducement to extend the maturity date of the notes. As a result of these modifications, for the year
ended December&nbsp;31, 2020 and 2019, the Company recorded in the consolidated statements of income a &#147;loss on debt extinguishment&#148; of approximately $777,000 and $290,000 and recorded in the consolidated statements of changes in
stockholders&#146; equity (deficit) under the caption &#147;debt modification&#148; the fair value of the warrants issued. The Company performed a present value cash flow analysis prior to the modification, and immediately after the modification to
determine if the amendments resulted in a substantial modification. The Company utilized a Black-Scholes model utilizing various assumptions at the modification date to value the common stock warrants. We identified the modification of the
convertible promissory notes as a critical audit matter. The accounting for the extinguishment is complex, and requires review of present value analysis to determine the necessity to apply extinguishment accounting. Significant audit effort was
required to understand the nature of the multiple amendments to the promissory note agreements, as well as amendments to the warrants associated with the notes. </P>

generally accepted in the United States of America. </P> <P STYLE="margin-top:18pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman"><B>Consideration of the Company&#146;s Ability to Continue as a Going Concern </B></P>
<P STYLE="margin-top:6pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman">The accompanying consolidated financial statements have been prepared assuming that the Company will continue as a going concern. As discussed in Note O to the
consolidated financial statements, the Company has incurred significant losses and they may be unsuccessful in raising the necessary capital to fund operations and capital expenditures. These conditions raise substantial doubt about the
Company&#146;s ability to continue as a going concern. Management&#146;s plans regarding those matters are also described in Note O. The consolidated financial statements do not include any adjustments that might result from the outcome of this
uncertainty. </P> <P STYLE="margin-top:18pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman"><B>Basis for Opinion </B></P> <P STYLE="margin-top:6pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman">These consolidated
financial statements are the responsibility of the Company&#146;s management. Our responsibility is to express an opinion on the Company&#146;s consolidated financial statements based on our audit. We are a public accounting firm registered with the
Public Company Accounting Oversight Board (United States) (PCAOB) and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and
Exchange Commission and the PCAOB. </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman">We conducted our audit in accordance with the standards of the PCAOB. Those standards require that we plan and perform
the audit to obtain reasonable assurance about whether the consolidated financial statements are free of material misstatement, whether due to error or fraud. The Company is not required to have, nor were we engaged to perform, an audit of its
internal control over financial reporting. As part of our audit, we are required to obtain an understanding of internal control over financial reporting, but not for the purpose of expressing an opinion on the effectiveness of the Company&#146;s
internal control over financial reporting. Accordingly, we express no such opinion. </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman">Our audit included performing procedures to assess the risks of
material misstatement of the consolidated financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures
in the consolidated financial statements. Our audit also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the consolidated financial statements. We
believe that our audit provides a reasonable basis for our opinion. </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman">FERLITA, WALSH, GONZALEZ&nbsp;&amp; RODRIGUEZ, P.A. </P>

<FONT STYLE="white-space:nowrap">No.&nbsp;2020-06,</FONT> Debt-Debt with Conversion and Other Options (Subtopic <FONT STYLE="white-space:nowrap">470-20)</FONT> and Derivatives and Hedging-Contracts in Entity&#146;s Own Equity (Subtopic <FONT
STYLE="white-space:nowrap">815-40).</FONT> The amendments in this Update are effective for public business entities that meet the definition of a Securities and Exchange Commission (SEC) filer, excluding entities eligible to be smaller reporting
companies as defined by the SEC, for fiscal years beginning after December&nbsp;15, 2021, including interim periods within those fiscal years. For all other entities, the amendments are effective for fiscal years beginning after December&nbsp;15,
2023, including interim periods within those fiscal years. Early adoption is permitted, but no earlier than fiscal years beginning after December&nbsp;15, 2020, including interim periods within those fiscal years. The Board specified that an entity
should adopt the guidance as of the beginning of its annual fiscal year. </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:9%; font-size:10pt; font-family:Times New Roman">The amendments in the above Update affect entities that issue
convertible instruments and/or contracts in an entity&#146;s own equity. For convertible instruments, the instruments primarily affected are those issued with beneficial conversion features or cash conversion features because the accounting models
for those specific features are removed. However, all entities that issue convertible instruments are affected by the amendments to the disclosure requirements in this Update. For contracts in an entity&#146;s own equity, the contracts primarily
affected are freestanding instruments and embedded features that are accounted for as derivatives under the current guidance because of failure to meet the settlement conditions of the derivatives scope exception related to certain requirements of
the settlement assessment. The Board simplified the settlement assessment by removing the requirements (1)&nbsp;to consider whether the contract would be settled in registered shares, (2)&nbsp;to consider whether collateral is required to be posted,
and (3)&nbsp;to assess shareholder rights. Those amendments also affect the assessment of whether an embedded conversion feature in a convertible instrument qualifies for the derivatives scope exception. Additionally, the amendments in this Update
affect the diluted EPS calculation for instruments that may be settled in cash or shares and for convertible instruments. The Company has not elected early adoption of this ASU. </P>
<P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:9%; font-size:10pt; font-family:Times New Roman">On October 31, 2018, the SEC adopted a final rule (&#147;New Final Rule&#148;) that will replace SEC&nbsp;Industry&nbsp;Guide&nbsp;7&nbsp;with

therefore, the adoption of this standard did not have a material impact on the Company&#146;s financial statements. </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:9%; font-size:10pt; font-family:Times New Roman">Revenue is recognized
when a customer obtains control of promised goods or services, in an amount that reflects the consideration which the Company expects to receive in exchange for those goods or services. To determine revenue recognition for arrangements that the
Company determines are within the scope of ASC Topic 606, the Company performs the following five steps: (i)&nbsp;identify the contract(s) with a customer; (ii)&nbsp;identify the performance obligations in the contract; (iii)&nbsp;determine the
transaction price; (iv)&nbsp;allocate the transaction price to the performance obligations in the contract; and (v)&nbsp;recognize revenue when (or as) the Company satisfies a performance obligation. The Company only applies the five-step model to
contracts when it is probable that the Company will collect the consideration it is entitled to in exchange for the goods or services it transfers to the customer. At contract inception, once the contract is determined to be within the scope of ASC
Topic 606, the Company assesses the goods or services promised within each contract and determines those that are performance obligations and assesses whether each promised good or service is distinct. The Company then recognizes as revenue the
amount of the transaction price that is allocated to the respective performance obligation when (or as) the performance obligation is satisfied. Sales, value add, and other taxes collected on behalf of third parties are excluded from revenue. </P>
<P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:9%; font-size:10pt; font-family:Times New Roman">The Company currently generates revenues from four customers with contracts. There are two sources of revenue, marine services, and other
services. The contracts for both services provide research, scientific services, marine operations planning, management execution, and project management. These services are billed generally on a monthly basis and recognized as revenue as the
services are performed. Revenue is recognized at a point in time as services are provided, as the customers simultaneously receive and consume the benefits provided by the Company each month. The Company generally does not receive any upfront
consideration for these services, and there is no variable consideration for the services.&nbsp;Costs associated with both services include all direct consulting labor, and minimal supplies, and is charged to operations as a component of Operations
and Research. </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:9%; font-size:10pt; font-family:Times New Roman">Accounts receivable are based on amounts billed to customers. Generally accepted accounting principles state an estimate is
to be made for an allowance for doubtful accounts. We have determined no allowance is currently necessary. If we were to have a recorded allowance, the accounts receivable would be stated net of the recorded allowance. </P>

Decisions are based on several factors, including, but not limited to, management&#146;s plans for future operations, recent operating results and projected cash flows. Impairment losses are included in depreciation at the time of impairment. We did
not have any impairments in 2020, 2019 or 2018. </P> <P STYLE="margin-top:18pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman"><B>Property and Equipment and Depreciation </B></P>

assets&#146; estimated useful lives which are normally between three and thirty years. Leasehold improvements are amortized over their estimated useful lives or lease term, if shorter. Items that may require major overhauls (such as engines or
generators) that enhance or extend the useful life of vessel related assets qualify to be capitalized and depreciated over the useful life or remaining life of that asset, whichever was shorter. Certain major repair items required by industry
standards to ensure a vessel&#146;s seaworthiness also qualified to be capitalized and depreciated over the period of time until the next scheduled planned major maintenance for that item. All other repairs and maintenance were accounted for under
the direct-expensing method and are expensed when incurred. </P> <P STYLE="margin-top:18pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman"><B>Earnings Per Share </B></P>
<P STYLE="margin-top:6pt; margin-bottom:0pt; text-indent:9%; font-size:10pt; font-family:Times New Roman">Basic earnings per share (&#147;EPS&#148;) is computed by dividing income available to common stockholders by the weighted-average number of
common shares outstanding for the period. In periods when the Company has income, the Company would calculate basic earnings per share using the <FONT STYLE="white-space:nowrap">two-class</FONT> method, if required, pursuant to ASC 260 <I>Earnings
Per Share.</I> The <FONT STYLE="white-space:nowrap">two-class</FONT> method was required effective with the issuance of certain senior convertible notes in the past because these notes qualified as a participating security, giving the holder the
right to receive dividends should dividends be declared on common stock. Under the <FONT STYLE="white-space:nowrap">two-class</FONT> method, earnings for a period are allocated on a pro rata basis to the common stockholders and to the holders of
convertible notes based on the weighted average number of common shares outstanding and number of shares that could be issued upon conversion. The Company does not use the <FONT STYLE="white-space:nowrap">two-class</FONT> method in periods when it
generates a loss because the holder of the convertible notes does not participate in losses. Currently, we do not have any outstanding convertible notes that qualify as a participating security. </P>
<P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:9%; font-size:10pt; font-family:Times New Roman">Diluted EPS reflects the potential dilution that would occur if dilutive securities and other contracts to issue common stock were exercised
or converted into common stock or resulted in the issuance of common stock that then shared in our earnings. We use the treasury stock method to compute potential common shares from stock options and warrants and the
<FONT STYLE="white-space:nowrap">if-converted</FONT> method to compute potential common shares from preferred stock, convertible notes or other convertible securities. For diluted earnings per share, the Company uses the more dilutive of the <FONT
STYLE="white-space:nowrap">if-converted</FONT> method or <FONT STYLE="white-space:nowrap">two-class</FONT> method. When a net loss occurs, potential common shares have an anti-dilutive effect on earnings per share and such shares are excluded from

<P STYLE="margin-top:6pt; margin-bottom:0pt; text-indent:9%; font-size:10pt; font-family:Times New Roman">Financial instruments consist of cash, evidence of ownership in an entity, and contracts that both (i)&nbsp;impose on one entity a contractual
obligation to deliver cash or another financial instrument to a second entity, or to exchange other financial instruments on potentially unfavorable terms with the second entity, and (ii)&nbsp;conveys to that second entity a contractual right
(a)&nbsp;to receive cash or another financial instrument from the first entity, or (b)&nbsp;to exchange other financial instruments on potentially favorable terms with the first entity. Accordingly, our financial instruments consist of cash and cash
equivalents, accounts receivable, accounts payable, accrued liabilities, derivative financial instruments and mortgage and loans payable. We carry cash and cash equivalents, accounts payable and accrued liabilities, and mortgage and loans payable at
the approximate fair market value, and, accordingly, these estimates are not necessarily indicative of the amounts that we could realize in a current market exchange. We carry derivative financial instruments at fair value as is required under
current accounting standards. </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:9%; font-size:10pt; font-family:Times New Roman">Derivative financial instruments consist of financial instruments or other contracts that contain a
notional amount and one or more underlying variables (e.g., interest rate, security price or other variable), require no initial net investment and permit net settlement. Derivative financial instruments may be free-standing or embedded in other
financial instruments. Further, derivative financial instruments are initially, and subsequently, measured at fair value and recorded as liabilities or, in rare instances, assets. We generally do not use derivative financial instruments to hedge
exposures to cash-flow, market or foreign-currency risks. However, we have entered into certain other financial instruments and contracts with features that are either (i)&nbsp;not afforded equity classification, (ii)&nbsp;embody risks not clearly
and closely related to host contracts, or (iii)&nbsp;may be <FONT STYLE="white-space:nowrap">net-cash</FONT> settled by the counterparty. As required by ASC 815 &#150; <I>Derivatives and Hedging</I>, these instruments are required to be carried as
derivative liabilities, at fair value, in our financial statements with changes in fair value reflected in our income. </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:9%; font-size:10pt; font-family:Times New Roman">We adopted ASC
Topic 820 for certain financial instruments measured as fair value on a recurring basis. ASC Topic 820 defines fair value, established a framework for measuring fair value in accordance with accounting principles generally accepted in the United
States and expands disclosures about fair value measurements. Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date.
ASC Topic 820 established a three-tier fair value hierarchy which prioritizes the inputs used in measuring fair value. </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:9%; font-size:10pt; font-family:Times New Roman">The hierarchy

Bismarck did not meet the definition of a business so the transaction represented an acquisition of assets rather than a business combination. Asset acquisitions do not give rise to goodwill. Rather, the sum of the fair value of the consideration
given, together with transaction costs is allocated to the individual assets acquired and liabilities assumed based on their relative fair values which were more clearly evident and, thus, more reliably measurable at the date of acquisition under
ASC <FONT STYLE="white-space:nowrap"><FONT STYLE="white-space:nowrap"><FONT STYLE="white-space:nowrap">805-50-30-2</FONT></FONT></FONT> <I>Initial Measurement</I>. In the future, the recoverability will be tested whenever events or changes in

two years. Per ASC <FONT STYLE="white-space:nowrap"><FONT STYLE="white-space:nowrap"><FONT STYLE="white-space:nowrap">350-30-35-3,</FONT></FONT></FONT> management has deemed the rights to this license to have an indefinite life. Determining if the
rights to the license has an indefinite or finite life required us to consider the nature of the renewal process and any additional economic factors, if any, required when renewing this license. We currently expect to use and renew the related
license indefinitely, and we do not believe there are currently any legal, regulatory, or contractual provisions that are expected to limit the useful life of the related exploration license or indicate that the useful life is other than indefinite.
The exploration license is also not dependent on, or specifically associated with, another asset or group of assets that would limit the useful life of the intangible asset or indicate that the useful life is other than indefinite. Management&#146;s
assumptions regarding our ability to successfully renew or extend the exploration license are based on Bismarck&#146;s historical experience. Bismarck was established in 2006, and they have historically renewed and extended the exploration license
without a lapse in their ability to use the license. The license has also never been revoked. We will not incur significant maintenance costs related to the license. There is an annual fee due of approximately $14,000 to maintain the license. This
amount is much less than the carrying amount of the license and the cost is not expected to prohibit continued renewals of the license in the future. Based on all the factors considered above, management believes it is appropriate to assign
indefinite useful life to the acquisition of the rights for the exploration license. </P>

convertible into an aggregate of 261,200 shares of Class&nbsp;B <FONT STYLE="white-space:nowrap">non-voting</FONT> common stock. Our holdings now constitute an approximate 14% ownership in NMI. At December&nbsp;31, 2020, our estimated share of
unrecognized NMI equity-method losses is approximately $21.3&nbsp;million. We have not recognized the accumulated $21.3&nbsp;million in our income statement because these losses exceeded our investment in NMI. Our investment has a carrying value of
zero as a result of the recognition of our share of prior losses incurred by NMI under the equity method of accounting. We believe it is appropriate to allocate this loss carryforward of $21.3&nbsp;million to any incremental NMI investment that may
be recognized on our balance sheet in excess of zero since the losses occurred when they were an equity-method investment. The aforementioned loss carryforward is based on NMI&#146;s last unaudited financial statements as of December&nbsp;31, 2016.
We do not believe losses NMI may have incurred subsequent to the December&nbsp;31, 2016 audit to be material. We do not have any financial obligations to NMI, and we are not committed to provide financial support to NMI. </P>

Limited (&#147;CRPL&#148;). In exchange for our 9,320,348 shares of CRP we received 141,884 shares of CPRL, which represents equity ownership of, at most, approximately 1% of the surviving entity. Since CRP was a thinly traded stock and pursuant to
guidance per ASC 320: <I>Debt and Equity Securities</I> regarding readily determinable fair value, we believe it was appropriate to not recognize this amount as an asset nor as revenue during that period. We continue to carry the value of our
investment in CPRL at zero in our consolidated financial statements. </P> <P STYLE="margin-top:18pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman"><B><I>CIC, LLC </I></B></P>
<P STYLE="margin-top:6pt; margin-bottom:0pt; text-indent:9%; font-size:10pt; font-family:Times New Roman">In 2018, we began providing services to CIC LLC, a company controlled by Greg Stemm, the past Chairman of the Board for Odyssey (See NOTE J for
related parties). This company is pursuing deep water mining permits in foreign waters. Due to the initial structure of the company, we determined this venture to be a VIE consistent with ASU 2015-2. We have determined that we are not the primary
beneficiary of the VIE and, therefore, we have not consolidated this entity. Additionally, we also will record the investment under the cost method as we have determined we do not exercise significant influence over the entity. We will assess our
investment for impairment annually and, if a loss in value is deemed other than temporary, an impairment charge will be recorded. At December&nbsp;31, 2020, the accumulated investment in the entity is $2,370,794, which is classified as an investment
in unconsolidated entity in our consolidated balance sheets. The original agreements relating to the equity investment were executed in January 2019. The original agreement was replaced in August of 2020 with a new agreement effective August&nbsp;1,
2020. </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:9%; font-size:10pt; font-family:Times New Roman">We account for the investments we make in certain legal entities in which equity investors do not have (1)&nbsp;sufficient equity
at risk for the legal entity to finance its activities without additional subordinated financial support, or (2)&nbsp;as a group, the holders of the equity investment at risk do not have either the power, through voting or similar rights, to direct
the activities of the legal entity that most significantly impact the entity&#146;s economic performance, or (3)&nbsp;the obligation to absorb the expected losses of the legal entity or the right to receive expected residual returns of the legal
entity. These legal entities are referred to as &#147;variable interest entities&#148; or &#147;VIEs.&#148; </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:9%; font-size:10pt; font-family:Times New Roman">We would consolidate the

the VIE&#146;s economic performance and the obligation to absorb the losses of, or right to receive benefits from, the VIE that could be potentially significant to the VIE. On a quarterly basis, we reassess whether we have a controlling financial

<P STYLE="margin-top:6pt; margin-bottom:0pt; text-indent:9%; font-size:10pt; font-family:Times New Roman">On August&nbsp;14, 2014, we entered into a Loan Agreement with Monaco Financial, LLC (&#147;Monaco&#148;), a strategic marketing partner,
pursuant to which Monaco agreed to lend us up to $10.0&nbsp;million. The loan was issued in three tranches: (i) $5.0&nbsp;million (the &#147;First Tranche&#148;) was advanced upon execution of the Loan Agreement; (ii) $2.5&nbsp;million (the
&#147;Second Tranche&#148;) was advanced on October&nbsp;1, 2014; and (iii) $2.5&nbsp;million (the &#147;Third Tranche&#148;) was advanced on December&nbsp;1, 2014. The Notes bear interest at a rate equal to 11% per annum. The Notes also contain an
option whereby Monaco can purchase shares of Oceanica held by Odyssey (the &#147;Share Purchase Option&#148;) at a purchase price that is the lower of (a) $3.15 per share or (b)&nbsp;the price per share of a contemplated equity offering of Oceanica
which totals $1.0&nbsp;million or more in the aggregate. The share purchase option was not clearly and closely related to the host debt agreement and required bifurcation. </P>
<P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:9%; font-size:10pt; font-family:Times New Roman">On December&nbsp;10, 2015, these promissory notes were amended as part of the asset acquisition agreement with Monaco (See NOTE R in our Form <FONT
STYLE="white-space:nowrap">10-K</FONT> filed with the Securities and Exchange Commission for the period ended December&nbsp;31, 2017 for further information). The amendment included the following material changes: (i) $2.2&nbsp;million of the
indebtedness represented by the Notes was extinguished, (ii) $5.0&nbsp;million of the indebtedness represented by the Notes ceased to bear interest and is only repayable under certain circumstances from certain sources of cash, and (iii)&nbsp;the
maturity date on the Notes was extended to December&nbsp;31, 2017. During March 2016, the maturity date was further extended to April&nbsp;1, 2018 and the exercise price of the Share Purchase Option was
<FONT STYLE="white-space:nowrap">re-priced</FONT> to $1.00 per share. This indebtedness has matured, but Monaco has not demanded payment because we are in negotiations with Monaco. As of the maturity date, the interest rate was adjusted to the
default rate of 18% per annum. See &#147;Loan Modification (March 2016)&#148; below. For the twelve months ended December&nbsp;31, 2020 and 2019, interest expense in the amount of $574,680 and $573,110, respectively, was recorded. The outstanding
interest-bearing balance of these Notes is $2.8&nbsp;million at December&nbsp;31, 2020 and 2019. </P>

<P STYLE="margin-top:6pt; margin-bottom:0pt; text-indent:9%; font-size:10pt; font-family:Times New Roman">In March 2016, Monaco agreed to lend us an additional $1,825,000. These loan proceeds were received in full during the first quarter of 2016.
The indebtedness bears interest at 10.0% percent per year. All principal and any unpaid interest was payable on April&nbsp;15, 2018. This indebtedness has matured, but Monaco has not demanded payment because we are in negotiations with Monaco. As of
the maturity date, the interest rate was adjusted to the default rate of 18% per annum. The current outstanding balance as of December&nbsp;31, 2020 and 2019 was $1,175,000. The indebtedness is convertible at any time until the maturity date into
shares of Oceanica held by us at a conversion price of $1.00 per share. Pursuant to this loan and as security for the indebtedness, Monaco was granted a second priority security interest in <FONT STYLE="white-space:nowrap">(a)&nbsp;one-half</FONT>
of the indebtedness evidenced by the Amended and Restated Consolidated Note and Guaranty, dated September&nbsp;25, 2015 (the &#147;ExO Note&#148;), in the original principal amount of $18.0&nbsp;million, issued by Exploraciones Oceanicas S. de R.L.
de C.V. to Oceanica Marine Operations, S.R.L. (&#147;OMO&#148;), and all rights associated therewith (the &#147;OMO Collateral&#148;); and (b)&nbsp;all technology and assets in our possession or control used for offshore exploration, including an
ROV system, <FONT STYLE="white-space:nowrap">deep-tow</FONT> search systems, winches, multi-beam sonar, and other equipment. The carrying net book value of this equipment is less than $0.1&nbsp;million. We unconditionally and irrevocably guaranteed
all obligations of ours and our subsidiaries to Monaco under this loan agreement. As further consideration for the loan, Monaco was granted an option (the &#147;Option&#148;) to purchase the OMO Collateral. The Option is exercisable at any time
before the earlier of (a)&nbsp;the date that is 30 days after the loan is paid in full or (b)&nbsp;the maturity date of the ExO Note, for aggregate consideration of $9.3&nbsp;million, $1.8&nbsp;million of which would be paid at the closing of the
exercise of the Option, with the balance paid in ten monthly installments of $750,000. During 2017, we sold a marine vessel to a related party of Monaco for $650,000.&nbsp;The consideration for this vessel was applied against our loan balance to
Monaco in the amount of $650,000. </P> <P STYLE="margin-top:18pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman"><B><I>Accounting considerations </I></B></P>
<P STYLE="margin-top:6pt; margin-bottom:0pt; text-indent:9%; font-size:10pt; font-family:Times New Roman">ASC 815 generally requires the analysis of embedded terms and features that have characteristics of derivatives to be evaluated for bifurcation
and separate accounting in instances where their economic risks and characteristics are not clearly and closely related to the risks of the host contract. The option to purchase the OMO Collateral is an embedded feature that is not clearly and
closely related to the host debt agreement and thus requires bifurcation. Because the option is out of the money, it has no material fair value as of the inception date or currently. The debt agreement did not contain any additional embedded terms
or features that have characteristics of derivatives. However, we were required to consider whether the hybrid contract embodied a beneficial conversion feature (&#147;BCF&#148;). The calculation of the effective conversion amount did result in a
BCF because the effective conversion price was less than the market price on the date of issuance, therefore a BCF of $456,250 was recorded. This BCF has been fully amortized as of March&nbsp;31, 2018. A total of $252,940 has been previously charged

<P STYLE="margin-top:6pt; margin-bottom:0pt; text-indent:9%; font-size:10pt; font-family:Times New Roman">In connection with the Acquisition Agreement entered into with Monaco on December&nbsp;10, 2015, Monaco agreed to modify certain terms of the
loans as partial consideration for the purchase of assets. For the First Tranche ($5,000,000 advanced on August&nbsp;14, 2014), Monaco agreed to cease interest as of December&nbsp;10, 2015 and reduce the loan balance by (i)&nbsp;the cash or other
value received from the SS <I>Central America</I> shipwreck project (&#147;SSCA&#148;) or (ii)&nbsp;if the proceeds received from the SSCA project were insufficient to pay off the loan balance by December&nbsp;31, 2017, then Monaco could seek
repayment of the remaining outstanding balance on the loan by withholding Odyssey&#146;s 21.25% &#147;additional consideration&#148; in new shipwreck projects performed for Monaco in the future. For the Second Tranche ($2,500,000 advanced on
October&nbsp;1, 2014), Monaco agreed to reduce the principal amount by $2,200,000 leaving a new principal balance of $300,000 and extension of maturity to December&nbsp;31, 2017. For the Third Tranche ($2,500,000 advanced on December&nbsp;1, 2014),
Monaco agreed to the extension of maturity to December&nbsp;31, 2017. </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:9%; font-size:10pt; font-family:Times New Roman">On December&nbsp;10, 2015, the Monaco call option related to the

combined total indebtedness of Monaco&#146;s Note 1 and Note 2, Monaco can convert this debt into 3,174,603 shares of Oceanica at a fixed conversion price of $1.00 per share, or $3,174,603. Any remaining debt in excess of $3,174,603 is not
convertible. Additionally, the modification eliminated Monaco&#146;s option (&#147;share purchase option&#148;) to purchase 3,174,603 shares of Oceanica stock at a price of $3.15 per share. The modification was analyzed under ASC 480
<I>Distinguishing Liabilities from Equity</I> (&#147;ASC 480&#148;) to determine if extinguishment accounting was applicable. Under ASC </P>

MINOSA </B></P> <P STYLE="margin-top:6pt; margin-bottom:0pt; text-indent:9%; font-size:10pt; font-family:Times New Roman">On March&nbsp;11, 2015, in connection with a Stock Purchase Agreement, Minera del Norte, S.A. de C.V. (&#147;MINOSA&#148;)
agreed to lend us up to $14.75&nbsp;million. The entire $14.75&nbsp;million was loaned in five advances from March&nbsp;11 through June&nbsp;30, 2015. The outstanding indebtedness bears interest at 8.0% percent per annum. The Promissory Note was
amended on April&nbsp;10, 2015 and on October&nbsp;1, 2015 so that, unless otherwise converted as provided in the Note, the adjusted principal balance shall be due and payable in full upon written demand by MINOSA; provided that MINOSA agreed that
it shall not demand payment of the adjusted principal balance earlier than the first to occur of: (i)&nbsp;30 days after the date on which (x)&nbsp;SEMARNAT makes a determination with respect to the current application for the Manifestacion de
Impacto Ambiental relating to phosphate deposit project, which determination is other than an approval or (y)&nbsp;Odyssey Marine Enterprises or any of its affiliates withdraws such application without MINOSA&#146;s prior written consent;
(ii)&nbsp;termination by Odyssey of the Stock Purchase Agreement, dated March&nbsp;11, 2015 (the &#147;Purchase Agreement&#148;), among Odyssey, MINOSA, and Penelope Mining, LLC (the &#147;Investor&#148;); (iii)&nbsp;the occurrence of an event of
default under the Promissory Note; (iv)&nbsp;December 31, 2015; or (v)&nbsp;if and only if the Investor shall have terminated the Purchase Agreement pursuant to Section&nbsp;8.1(d)(iii) thereof, March&nbsp;30, 2016. This indebtedness is classified
as short-term debt. In connection with the loans, we granted MINOSA an option to purchase our 54% interest in Oceanica for $40.0&nbsp;million (the &#147;Oceanica Call Option&#148;). On March&nbsp;11, 2016, the Oceanica Call has expired. Completion
of the transaction requires amending the Company&#146;s articles of incorporation to (a)&nbsp;effect a reverse stock split, which was implemented on February&nbsp;19, 2016, (b)&nbsp;adjusting the Company&#146;s authorized capitalization, which was
also implemented on February&nbsp;19, 2016, and (c)&nbsp;establishing a classified board of directors (collectively, the &#147;Amendments&#148;). The Amendments have been or will be set forth in certificates of amendment to the Company&#146;s
articles of incorporation filed or to be filed with the Nevada Secretary of State. As collateral for the loan, we granted MINOSA a security interest in the Company&#146;s 54% interest in Oceanica. The outstanding principal balance of this debt was
$14.75&nbsp;million at December&nbsp;31, 2020 and 2019, respectively. The maturity date of this indebtedness has been amended and matured on March&nbsp;18, 2017. Per Note 6 MINOSA 2 below, the Minosa Purchase Agreement amended the due date of this
note to a due date which may be no earlier than December&nbsp;31, 2017, that is at least 60 days subsequent to written notice that Minosa intends to demand payment. See Note 6 &#150; MINOSA 2 for further qualifications. During December 2017, MINOSA
transferred this debt to its parent company. For the twelve months ended December&nbsp;31, 2020 and 2019, interest in the amount of $1,183,230 and $1,180,000, respectively, was recorded. </P>

instruments issued. Prior to making the accounting allocation, we evaluated for proper classification under ASC 480 <I>Distinguishing Liabilities from Equity</I> (&#147;ASC 480&#148;), ASC 815 <I>Derivatives and Hedging</I> (&#147;ASC 815&#148;) and

that have characteristics of derivatives. The Oceanica Call Option is considered a freestanding financial instrument because it is both (i)&nbsp;legally detachable and (ii)&nbsp;separately exercisable. The Oceanica Call Option did not fall under the
guidance of ASC 480. Additionally, it did not meet the definition of a derivative under ASC 815 because the option has a fixed value of $40.0&nbsp;million and does not contain an underlying variable which is indicative of a derivative. This
instrument is considered an option contract for a sale of an asset. The guidance applied in this case is ASC <FONT STYLE="white-space:nowrap">360-20,</FONT> which provides that in situations when a party lends funds to a seller and is given an
option to buy the property at a certain date in the future, the loan shall be recorded at its present value using market interest rates and any excess of the proceeds over that amount credited to an option deposit account. If the option is
exercised, the deposit shall be included as part of the sales proceeds; if not exercised, it shall be credited to income in the period in which the option lapses. </P>

(&#147;Epsilon&#148;). Pursuant to the Purchase Agreement, Epsilon loaned us $3.0&nbsp;million in two installments of $1.5&nbsp;million on March&nbsp;31, 2016 and April&nbsp;30, 2016. The indebtedness bears interest at a rate of 10% per annum and
was due on March&nbsp;18, 2017. We were also responsible for $50,000 of the lender&#146;s out of pocket costs. This amount is included in the loan balance. In pledge agreements related to the loans, we granted security interests to Epsilon in

notice to us or upon a merger, consolidation, third party tender offer, or similar transaction relating to us at the conversion price of $5.00 per share, which represents the <FONT STYLE="white-space:nowrap">five-day</FONT> volume-weighted average
price of Odyssey&#146;s common stock for the five trading day period ending on March&nbsp;17, 2016. On January&nbsp;25, 2017, Epsilon provided notice to us that it would convert the initial $3.0&nbsp;million plus accrued interest per the Restated

outstanding tranche (other than the first $3.0&nbsp;million already advanced) under this Restated Note in excess of 1,388,769 shares of common stock.&nbsp;The additional tranches were issued as follows: (a) $1,000,000 (&#147;Tranche 3&#148;) was

January 2020 this Loan Agreement was amended by increasing the interest rate to 18%. On April&nbsp;20, 2018, the loan was amended, and the principal amount of the Loan was increased to $3,500,000. The loan balance at December&nbsp;31, 2020 and 2019

subsidiary of ours. The conversion value of $1.0&nbsp;million equates to 10% of the equity interest in Aldama. If the holder elects to acquire the entire 50% of the equity interest, the Holder has to pay the deficiency in cash. As additional

to the number of Conversion Shares previously issued upon conversion of any of the Notes sold pursuant to the Purchase Agreement, would represent in excess of 19.9% of the number of shares of Common Stock outstanding as of December&nbsp;6, 2019. Due
to a reference to the effective date of the amendment in the definition of the maturity date, the maturity date of the Note was inadvertently revised from June&nbsp;6, 2020 to November&nbsp;6, 2020. Thus, on December&nbsp;8, 2020 the Company amended
the Notes to adjust the maturity date back to the original date of June&nbsp;6, 2020 and to extend the option to convert to December&nbsp;31, 2020. The modifications were evaluated under FASB ASC Topic <FONT STYLE="white-space:nowrap"><FONT

accordance with ASC Topic 815, Derivatives and Hedging, and determined that they contain certain embedded derivatives whose economic risks and characteristics were not clearly and closely related to the risks of the host contract. The material
embedded derivative features consisted of the embedded conversion option and contingent redemption provisions. We elected to initially and subsequently measure the Notes in their entirety at fair value, with changes in fair value recognized in
earnings. FASB <FONT STYLE="white-space:nowrap"><FONT STYLE="white-space:nowrap">ASC&nbsp;825-10-25&nbsp;allows</FONT></FONT> us to elect the fair value option for recording financial instruments when they are initially recognized or if there is an

<P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:9%; font-size:10pt; font-family:Times New Roman">Because the Notes are carried in their entirety at fair value, the value of the compound embedded conversion feature is embodied in that fair
value. The Company estimates the fair value of the hybrid instrument based on a probability weighted analysis which considers the present value of the cash flows using a credit risk adjusted rate enhanced by the redemption feature and the value of
the conversion option valued using a Monte Carlo model. This method was considered by management to be the most appropriate method of encompassing the credit risk and exercise behavior that a market participant would consider when valuing the hybrid
financial instrument. </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:9%; font-size:10pt; font-family:Times New Roman">Inputs used to value the hybrid instrument during the year ended December&nbsp;31, 2020 included, (i)&nbsp;present

receive 50% of project proceeds until this amount is recouped. Thereafter, they will share in additional net proceeds of the project at the rate of 1% for every million invested. Subsequent to the original syndication deal, we reached an agreement
permitting Galt to bifurcate their selection between two projects, the SS <I>Gairsoppa</I> and HMS <I>Victory</I> with the residual 1% on additional net proceeds assigned to the HMS <I>Victory</I> project only. The bifurcation resulted in $3,756,250
being allocated to each of the two projects. Therefore, Galt will receive 7.5125% of net proceeds from the HMS <I>Victory</I> project after they recoup their investment of $3,756,250 plus three times the investment. Galt has been paid in full for
their share of the <I>Gairsoppa </I>project investment. There are no future payments remaining due to Galt for the <I>Gairsoppa</I> project. Based on the timing of the proceeds earmarked for Galt, the relative corresponding amount of Galt&#146;s
revenue participation right of $3,756,250 was amortized into revenue in 2012 based upon the percent of Galt-related proceeds from the sale of silver as a percentage of total proceeds that Galt earned under the revenue participation agreement ($15.0

distribution on its common stock in shares of common stock, subdivides its outstanding common stock into a greater number of shares, or combines its outstanding common stock into a smaller number of shares, or if there is a reorganization, or a
merger or consolidation of Odyssey with or into any other entity which results in a conversion, exchange, or cancellation of the common stock, or a sale of all or substantially all of Odyssey&#146;s assets, then the conversion rights described above
will be adjusted appropriately so that each holder of Series AA Preferred will receive the securities or other consideration the holder would have received if the holder&#146;s Series AA Preferred had been converted before the happening of the
event. The conversion price in effect from time to time is also subject to downward adjustment if we issue or sell shares of common stock for a purchase price less than the conversion price or if we issue or sell shares convertible into or

stated above the issuance of the Series AA Convertible Preferred Stock is based on certain contingencies. No accounting treatment determination is required until these contingencies are met and the Series AA Convertible Preferred Stock has been

<P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">ASC 480 generally requires liability classification for financial instruments that are certain to be redeemed, represent obligations to
purchase shares of stock or represent obligations to issue a variable number of common shares. We concluded that the Series AA Preferred was not within the scope of ASC 480 because none of the three conditions for liability classification was
present. </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">ASC 815 generally requires the analysis of embedded terms and features that have characteristics of derivatives to be evaluated
for bifurcation and separate accounting in instances where their economic risks and characteristics are not clearly and closely related to the risks of the host contract. However, in order to perform this analysis, we were first required to evaluate
the economic risks and characteristics of the Series AA Convertible Preferred Stock in its entirety as being either akin to equity or akin to debt. Our evaluation concluded that the Series AA Convertible Preferred Stock was more akin to an
equity-like contract largely due to the fact that most of its features were participatory in nature. As a result, we concluded that the embedded conversion feature is clearly and closely related to the host equity contract and will not require
bifurcation and liability classification. </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">The option to purchase the Series <FONT STYLE="white-space:nowrap">AA-2</FONT> Convertible

equity instruments cannot be granted but this plan will continue in effect until all outstanding awards have been exercised in full or are no longer exercisable and all equity instruments have vested or been forfeited. </P>
<P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:9%; font-size:10pt; font-family:Times New Roman">On June&nbsp;9, 2015, our stockholders approved our 2015 Stock Incentive Plan (the &#147;Plan&#148;) that was adopted by our Board of
Directors (the &#147;Board&#148;) on January&nbsp;2, 2015, which is the effective date. The plan expires on the tenth anniversary of the effective date. The Plan provides for the grant of incentive stock options,
<FONT STYLE="white-space:nowrap">non-qualified</FONT> stock options, restricted stock awards, restricted stock units and stock appreciation rights. This plan was initially capitalized with 450,000 shares that may be granted. The Plan is intended to
comply with Section&nbsp;162(m) of the Internal Revenue Code, which stipulates that the maximum aggregate number of Shares with respect to one or more Awards that may be granted to any one person during any calendar year shall be 83,333, and the
maximum aggregate amount of cash that may be paid in cash to any person during any calendar year with respect to one or more Awards payable in cash shall be $2,000,000. The original maximum number of shares that were to be used for Incentive Stock
Options (&#147;ISO&#148;) under the Plan was 450,000. During our June 2016 stockholders meeting, the stockholders approved the addition of 200,000 incremental shares to the Plan. With respect to each grant of an ISO to a participant who is not a ten
percent stockholder, the exercise price shall not be less than the fair market value of a share on the date the ISO is granted. With respect to each grant of an ISO to a participant who is a ten percent stockholder, the exercise price shall not be
less than one hundred ten percent (110%) of the fair market value of a share on the date the ISO is granted. If an award is a <FONT STYLE="white-space:nowrap">non-qualified</FONT> stock option (&#147;NQSO&#148;), the exercise price for each share
shall be no less than (1)&nbsp;the minimum price required by applicable state law, or (2)&nbsp;the fair market value of a share on the date the NQSO is granted, whichever price is greatest. Any award intended to meet the performance based exception
must be granted with an exercise price not less than the fair market value of a share determined as of the date of such grant. </P>

Plan (the &#147;2019 Plan&#148;), which was approved by our stockholders on June&nbsp;3, 2019. The 2019 Plan expires on June&nbsp;3, 2029. The 2019 Plan provides for the grant of incentive stock options,
<FONT STYLE="white-space:nowrap">non-qualified</FONT> stock options, restricted stock awards, restricted stock units and stock appreciation rights. The 2019 Plan is capitalized with 800,000 shares that may be granted. No awards were made from the
Plan prior to the effective date. The 2019 Plan includes the following features: no &#147;evergreen&#148; share reserve, prohibits liberal share recycling, no repricing permitted without stockholder approval, no stock option reload features, no
transfers of awards for value and dividends and dividends equivalent shall accrue and be paid only if and to the extent the common stock underlying the award become vested or payable. </P>
<P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:9%; font-size:10pt; font-family:Times New Roman">Share-based compensation expense recognized during the period is based on the value of the portion of share-based payment awards that is
ultimately expected to vest. As share-based compensation expense recognized in the statement of operations is based on awards ultimately expected to vest, it can be reduced for estimated forfeitures. The ASC topic Stock Compensation requires
forfeitures to be estimated at the time of grant and revised, if necessary, in subsequent periods if actual forfeitures differ from those estimates. The share-based compensation charged against income for the periods ended December&nbsp;31, 2020,
2019 and 2018 was $420,648, $756,596 and $415,615, respectively. The 2019 amount includes $675,000 of equity-based compensation issued from a subsidiary for director fees. </P>
<P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:9%; font-size:10pt; font-family:Times New Roman">We did not grant stock options to employees or outside directors in 2020, 2019 or 2018. If options were granted, their values would be
determined using the Black-Scholes-Merton option-pricing model, which values options based on the stock price at the grant date, the expected life of the option, the estimated volatility of the stock, the expected dividend payments, and the
risk-free interest rate over the life of the option. </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:9%; font-size:10pt; font-family:Times New Roman">The Black-Scholes-Merton option pricing model was developed for estimating the fair
value of traded options that have no vesting restrictions and are fully transferable. Because option valuation models require the use of subjective assumptions, changes in these assumptions can materially affect the fair value of the options. Our
options do not have the characteristics of traded options; therefore, the option valuation models do not necessarily provide a reliable measure of the fair value of our options. </P>

<P STYLE="margin-top:6pt; margin-bottom:0pt; text-indent:9%; font-size:10pt; font-family:Times New Roman">On August&nbsp;4, 2017, the Company&#146;s board of directors (the &#147;Board&#148;) adopted the Odyssey Marine Exploration, Inc. Key Employee
Cuota Appreciation Rights (the &#147;Key Employee Plan&#148;) and the Odyssey Marine Exploration, Inc. Nonemployee Director Cuota Appreciation Rights (the &#147;Director Plan&#148; and, together with the Key Employee Plan, the &#147;Cuota
Plans&#148;). The Cuota Plans provide for the award of cuota appreciation rights (&#147;CARs&#148;) to eligible participants. A &#147;cuota&#148; is a unit of equity interest under Panamanian law, and the value of the CARs will be determined based
upon the appreciation, if any, in the value of the cuotas of Oceanica Resources, S. de R.L., a Panamanian sociedad de responsabilidad limitada (&#147;Oceanica&#148;), after the award of such CARs. The Company indirectly holds a majority stake in
Oceanica. </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:9%; font-size:10pt; font-family:Times New Roman">The Board authorized the award of up to 750,000 CARs under the Key Employee Plan and the award of up to 600,000 CARs under the
Director Plan. The terms of any CARs awarded under the Cuota Plans will be set forth in an award agreement between the Company and each participant, and the award agreement will set forth a vesting schedule for the CARs. In general, unvested CARs
will be forfeited upon a participant&#146;s separation of service from the Company, and all vested and unvested CARs will be forfeited upon a participant&#146;s separation of service from the Company for &#147;cause&#148; (as defined in the Cuota
Plans). </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:9%; font-size:10pt; font-family:Times New Roman">Each participant in the Cuota Plans will be entitled to be paid the value of such participant&#146;s CARs upon the occurrence of
a &#147;payment event.&#148; As used in the Cuota Plans, payment events consist of a change in control of the Company or the date specified in the applicable award agreement and, in the case of the Key Employee Plan, a separation of service without
cause and the participant&#146;s continuous employment with the Company until the date specified in the applicable award agreement. The value of CARs liability will be based upon the difference between the basis in the cuotas of Oceanica on the date
of the award of the CARs, which is $3.00, and the fair value of the cuotas on the date used for the payment event, in each case as determined by the Board in accordance with the provisions of the Cuota Plans. The fair value of the cuota as of
August&nbsp;31, 2019 was $1.00. There is no active market for Oceanica&#146;s securities, and there was no activity that would have materially changed the valuation at December&nbsp;31, 2020. </P>

to meet our desired projected business plan requirements, we would be required to follow a contingency business plan which is based on curtailed expenses and fewer cash requirements. On
August&nbsp;21, 2020, we sold an aggregate of 2,553,314 shares of our common stock and warrants to purchase up to 1,901,989 shares of our common stock. The net proceeds received from this sale, after offering expenses of $0.3&nbsp;million, of which
$0.2&nbsp;million was withheld to cover fees, were $11.3&nbsp;million (See NOTE L). These proceeds, coupled with the anticipated cash inflows, were expected to provide operating funds through early 2022. </P>
<P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:9%; font-size:10pt; font-family:Times New Roman">On March&nbsp;11, 2015, we entered into a Stock Purchase Agreement with Minera del Norte S.A. de c.v. (&#147;MINOSA&#148;) and Penelope Mining

years in convertible preferred stock of Odyssey. The equity financing is subject to the satisfaction of certain conditions, including the approval of our stockholders which occurred on June&nbsp;9, 2015, and MINOSA and Penelope are currently under
no obligation to make the preferred share equity investments. </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:9%; font-size:10pt; font-family:Times New Roman">Our consolidated <FONT STYLE="white-space:nowrap">non-restricted</FONT>
cash balance at December&nbsp;31, 2020 was $6.2&nbsp;million. We have a working capital deficit at December&nbsp;31, 2020 of $47.0&nbsp;million. Our largest loan of $14.75&nbsp;million from MINOSA had a due date of December&nbsp;31, 2017 which is
now linked to other stipulations, see NOTE H for further detail. The majority of our remaining assets have been pledged to MINOSA, and its affiliates, and to Monaco Financial LLC, leaving us with few opportunities to raise additional funds from our
balance sheet. The total consolidated book value of our assets was approximately $11.8&nbsp;million at December&nbsp;31, 2020, which includes cash of $6.2&nbsp;million, and the fair market value of these assets may differ from their net carrying
book value. Even though we executed the above noted financing arrangement with Penelope, Penelope must purchase the shares for us to be able to complete the equity component of the transaction. The Penelope equity transaction is heavily dependent on
the outcome of our subsidiary&#146;s application approval process for an environmental permit (EIA) to commercially develop a mineralized phosphate deposit off the coast of Mexico. The factors noted above raise doubt about our ability to continue as
a going concern. These consolidated financial statements do not include any adjustments to the amounts and classification of assets and liabilities that may be necessary should we be unable to continue as a going concern. </P>

provides for annual increases of base rent of 3% until the expiration date. Pursuant to ASC 842, an operating lease right of usage (ROU) asset and liability were recognized in the amount of $590,612 at inception of the lease based on the present
value of lease payments over the remaining lease term. The ROU asset represents the Company&#146;s right to use the underlying office space asset for the lease term, and the lease liability represents the Company&#146;s obligation to make lease
payments arising from the lease. Since the implicit rate of interest in the arrangement was not readily determinable, we utilized our incremental borrowing rate of 10% in determining the present value of lease payments. The operating lease ROU asset

collateral, they were granted a primary lien on certain items of our marine equipment. The carrying value of this equipment is zero. This agreement matured in August of 2018. During the three-months ended June&nbsp;30, 2018, we sold various marine
equipment to Magellan for $1.0&nbsp;million and the assumption of this vendor&#146;s trade payable and accrued interest, however, we remain as guarantor on this trade payable. We recorded a gain of approximately $0.9&nbsp;million from the cash
proceeds alone. Included in this equipment is the equipment noted above the vendor has a primary lien on. The vendor has consented to Magellan&#146;s assumption of this debt but did not release us from our obligations. If Magellan defaults and the
vendor forecloses on this equipment currently in possession of Magellan, we then have a contingent liability to Magellan in the amount of $0.5&nbsp;million for two of the key assets. </P>

(&amp;#8220;Oceanica&amp;#8221;) to two attorneys for their future services. This equity would only be issuable upon the Mexican&amp;#8217;s government approval and issuance of the Environmental Impact Assessment (&amp;#8220;EIA&amp;#8221;) for our Mexican subsidiary. All possible grants of new equity shares were approved by the Administrators of Oceanica. We also owe consultants contingent success fees of up to $700,000 upon the approval and issuance of the EIA. The EIA has not been approved as of the date of this report. &lt;/div&gt;&lt;/div&gt;&lt;div style="font-family: times new roman; font-size: 10pt; margin-top: 18pt; margin-bottom: 0pt;"&gt;&lt;div style="font-family: &amp;quot;times new roman&amp;quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;"&gt;&lt;div style="font-weight:bold;display:inline;"&gt;Going Concern Consideration &lt;/div&gt;&lt;/div&gt;&lt;/div&gt;&lt;div style="text-indent: 9%; font-family: times new roman; font-size: 10pt; margin-top: 6pt; margin-bottom: 0pt;"&gt;&lt;div style="font-family: &amp;quot;times new roman&amp;quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;"&gt;We have experienced several years of net losses and may continue to do so. Our ability to generate net income or positive cash flows for the following twelve months is dependent upon financings, our success in developing and monetizing our interests in mineral exploration entities, generating income from exploration charters, collecting on amounts owed to us, and completing the MINOSA/Penelope equity financing transaction approved by our stockholders on June&amp;#160;9, 2015. &lt;/div&gt;&lt;/div&gt;&lt;div style="text-indent: 9%; font-family: times new roman; font-size: 10pt; margin-top: 12pt; margin-bottom: 0pt;"&gt;&lt;div style="font-family: &amp;quot;times new roman&amp;quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;"&gt;Our 2020 business plan required us to generate new cash inflows to effectively allow us to perform our planned projects. We continually plan to generate new cash inflows through the monetization of our receivables and equity stakes in seabed mineral companies, financings, syndications or other partnership opportunities. If cash inflow ever becomes insufficient to meet our desired projected business plan requirements, we would be required to follow a contingency business plan which is based on curtailed expenses and fewer cash requirements. On August&amp;#160;21, 2020, we sold an aggregate of 2,553,314 shares of our common stock and warrants to purchase up to 1,901,989 shares of our common stock. The net proceeds received from this sale, after offering expenses of $0.3&amp;#160;million, of which $0.2&amp;#160;million was withheld to cover fees, were $11.3&amp;#160;million (See NOTE L). These proceeds, coupled with the anticipated cash inflows, were expected to provide operating funds through early 2022. &lt;/div&gt;&lt;/div&gt;&lt;div style="text-indent: 9%; font-family: times new roman; font-size: 10pt; margin-top: 12pt; margin-bottom: 0pt;"&gt;&lt;div style="font-family: &amp;quot;times new roman&amp;quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;"&gt;On March&amp;#160;11, 2015, we entered into a Stock Purchase Agreement with Minera del Norte S.A. de c.v. (&amp;#8220;MINOSA&amp;#8221;) and Penelope Mining LLC (&amp;#8220;Penelope&amp;#8221;), an affiliate of MINOSA, pursuant to which (a)&amp;#160;MINOSA agreed to extend short-term, debt financing to Odyssey of up to $14.75&amp;#160;million, and (b)&amp;#160;Penelope agreed to invest up to $101&amp;#160;million over three years in convertible preferred stock of Odyssey. The equity financing is subject to the satisfaction of certain conditions, including the approval of our stockholders which occurred on June&amp;#160;9, 2015, and MINOSA and Penelope are currently under no obligation to make the preferred share equity investments. &lt;/div&gt;&lt;/div&gt;&lt;div style="text-indent: 9%; font-family: times new roman; font-size: 10pt; margin-top: 12pt; margin-bottom: 0pt;"&gt;Our consolidated &lt;div style="white-space: nowrap; letter-spacing: 0px; top: 0px;;display:inline;"&gt;non-restricted&lt;/div&gt; cash balance at December&amp;#160;31, 2020 was $6.2&amp;#160;million. We have a working capital deficit at December&amp;#160;31, 2020 of $47.0&amp;#160;million. Our largest loan of $14.75&amp;#160;million from MINOSA had a due date of December&amp;#160;31, 2017 which is now linked to other stipulations, see NOTE H for further detail. The majority of our remaining assets have been pledged to MINOSA, and its affiliates, and to Monaco Financial LLC, leaving us with few opportunities to raise additional funds from our balance sheet. The total consolidated book value of our assets was approximately $11.8&amp;#160;million at December&amp;#160;31, 2020, which includes cash of $6.2&amp;#160;million, and the fair market value of these assets may differ from their net carrying book value. Even though we executed the above noted financing arrangement with Penelope, Penelope must purchase the shares for us to be able to complete the equity component of the transaction. The Penelope equity transaction is heavily dependent on the outcome of our subsidiary&amp;#8217;s application approval process for an environmental permit (EIA) to commercially develop a mineralized phosphate deposit off the coast of Mexico. The factors noted above raise doubt about our ability to continue as a going concern. These consolidated financial statements do not include any adjustments to the amounts and classification of assets and liabilities that may be necessary should we be unable to continue as a going concern. &lt;/div&gt;&lt;div style="font-family: times new roman; font-size: 10pt; margin-top: 18pt; margin-bottom: 0pt;"&gt;&lt;div style="font-family: &amp;quot;times new roman&amp;quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;"&gt;&lt;div style="font-weight:bold;display:inline;"&gt;Lease commitment &lt;/div&gt;&lt;/div&gt;&lt;/div&gt;&lt;div style="text-indent: 9%; font-family: times new roman; font-size: 10pt; margin-top: 6pt; margin-bottom: 0pt;"&gt;In August 2019, we entered into an operating lease for our corporate office space under a &lt;div style="white-space: nowrap; letter-spacing: 0px; top: 0px;;display:inline;"&gt;non-cancellable&lt;/div&gt; lease through August 2024 with monthly payments ranging from $11,789 to $13,269, not including sales tax. The lease provides for annual increases of base rent of 3% until the expiration date. Pursuant to ASC 842, an operating lease right of usage (ROU) asset and liability were recognized in the amount of $590,612 at inception of the lease based on the present value of lease payments over the remaining lease term. The ROU asset represents the Company&amp;#8217;s right to use the underlying office space asset for the lease term, and the lease liability represents the Company&amp;#8217;s obligation to make lease payments arising from the lease. Since the implicit rate of interest in the arrangement was not readily determinable, we utilized our incremental borrowing rate of 10% in determining the present value of lease payments. The operating lease ROU asset includes any lease payments made and excludes lease incentives. &lt;/div&gt;&lt;div style="text-indent: 9%; font-family: times new roman; font-size: 10pt; margin-top: 12pt;

font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;"&gt;Professional fees are mainly attributable to legal fees and other professional services in support of operations. Compensation and incentives at December&amp;#160;31, 2020 includes $0.8&amp;#160;million accrued incentive awards for the company employees at December&amp;#160;31, 2019 and prior and $0.3&amp;#160;million additional for 2020. The Board of Directors will only approve incentives to be paid when and if there is sufficient excess cash above and beyond normal operating requirements. Other operating at December&amp;#160;31, 2020 contains general expense items resulting from general operations. The primary expense in Other operating $0.9&amp;#160;million is for accrued exploration permits. Accrued interest is due to several lenders per debt agreements described in NOTE H. During the quarter ended September&amp;#160;30, 2019, we received an earnest money deposit of $450,000 from a company controlled by Greg Stemm, our past Chairman of the Board (see NOTE J for further information). The earnest money deposit relates to a draft agreement related to potential sale of a stake of our equity in CIC. This transaction has not yet been consummated. Accrued insurance obligations for the years ended December&amp;#160;31, 2020 and 2019 primarily consisted of directors and officers insurance obligations. &lt;/div&gt;&lt;/div&gt;&lt;table border="0" style="width:100%; table-layout:fixed;" cellspacing="0" cellpadding="0"&gt;&lt;tr&gt;&lt;td&gt;&lt;/td&gt;&lt;/tr&gt;&lt;/table&gt;</us-gaap:AccountsPayableAndAccruedLiabilitiesDisclosureTextBlock>

We are providing these services pursuant to a Master Services Agreement that provides for&amp;#160;back office services in exchange for a recurring monthly fee as well as other mineral related services on a cost-plus profit basis and will be compensated for these services with a combination of cash and equity in CIC. For the 2020 year to date, we invoiced CIC a total of $848,588, which was for back office technical and support services.&amp;#160;We have the option to accept equity in payment of the amounts due from CIC. See NOTE C for related accounts receivable at December&amp;#160;31, 2020 and NOTE G for our investment in an unconsolidated entity. &lt;/div&gt;&lt;div style="text-indent: 9%; font-family: times new roman; font-size: 10pt; margin-top: 12pt; margin-bottom: 0pt;"&gt;&lt;div style="font-family: &amp;quot;times new roman&amp;quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;"&gt;During the quarter ended September&amp;#160;30, 2019, we received an earnest money deposit of $450,000 from a company controlled by Greg Stemm, our past Chairman of the Board. The earnest money deposit relates to a draft agreement related to potential sell of a stake of our equity in CIC. As of this report date, this transaction has not been consummated. The deposit is included in accrued expenses (NOTE I) in our statement of consolidated balance sheets. &lt;/div&gt;&lt;/div&gt;&lt;div style="text-indent: 9%; font-family: times new roman; font-size: 10pt; margin-top: 12pt; margin-bottom: 0pt;"&gt;During September 2019, we entered into an arrangement with a company controlled by one of our directors relating to its possible participation in a pending financing arrangement. Upon entering the arrangement, we received an earnest deposit of $150,000. If the company&amp;#8217;s participation was not required, the arrangement called for the return of the $150,000 deposit plus a &lt;div style="white-space: nowrap; letter-spacing: 0px; top: 0px;;display:inline;"&gt;&lt;div style="white-space: nowrap; letter-spacing: 0px; top: 0px;;display:inline;"&gt;10%&amp;#160;break-up-fee.&lt;/div&gt;&lt;/div&gt; The company&amp;#8217;s participation was not required. $145,000 remained payable to the director at December&amp;#160;31, 2019 and is included in accounts payable and other in our statement of consolidated balance sheets.

font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;"&gt;In a private placement that closed in September 2000, we sold &amp;#8220;units&amp;#8221; consisting of &amp;#8220;&lt;div style="font-style:italic;display:inline;;font-style:italic;display:inline;"&gt;Republic&amp;#8221;&lt;/div&gt; Revenue Participation Certificates and Common Stock. Each $50,000 &amp;#8220;unit&amp;#8221; entitled the holder to 1% of the gross revenue generated by the now named &amp;#8220;&lt;div style="font-style:italic;display:inline;;font-style:italic;display:inline;"&gt;Seattle&lt;/div&gt;&amp;#8221; project (formerly referred to as the &amp;#8220;&lt;div style="font-style:italic;display:inline;;font-style:italic;display:inline;"&gt;Republic&lt;/div&gt;&amp;#8221; project), and 100,000 shares of Common Stock. Gross revenue is defined as all cash proceeds payable to us as a result of the &amp;#8220;&lt;div style="font-style:italic;display:inline;;font-style:italic;display:inline;"&gt;Seattle&lt;/div&gt;&amp;#8221; project, excluding funds received by us to finance the project. &lt;/div&gt;&lt;/div&gt;&lt;div style="text-indent: 9%; font-family: times new roman; font-size: 10pt; margin-top: 12pt; margin-bottom: 0pt;"&gt;&lt;div style="font-family: &amp;quot;times new roman&amp;quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;"&gt;The participating rights balance will be amortized under the units of revenue method once management can reasonably estimate potential revenue for each of these projects. The RPCs for the above projects do not have a termination date; therefore, these liabilities will be carried on the books until revenue is recognized from these projects or we permanently abandon either project. &lt;/div&gt;&lt;/div&gt;&lt;div style="font-family: times new roman; font-size: 10pt; margin-top: 18pt; margin-bottom: 0pt;"&gt;&lt;div style="font-family: &amp;quot;times new roman&amp;quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;"&gt;&lt;div style="font-weight:bold;display:inline;"&gt;Galt Resources, LLC &lt;/div&gt;&lt;/div&gt;&lt;/div&gt;&lt;div style="text-indent: 9%; font-family: times new roman; font-size: 10pt; margin-top: 6pt; margin-bottom: 0pt;"&gt;&lt;div style="font-family: &amp;quot;times new roman&amp;quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;"&gt;In February 2011, we entered into a project syndication deal with Galt Resources LLC (&amp;#8220;Galt&amp;#8221;) for which they invested $7,512,500 representing rights to future revenues of any one project Galt selected prior to December&amp;#160;31, 2011. If the project is successful and generates sufficient proceeds, Galt will recoup their investment plus three times the investment. Galt&amp;#8217;s investment return will be paid out of project proceeds. Galt will receive 50% of project proceeds until this amount is recouped. Thereafter, they will share in additional net proceeds of the project at the rate of 1% for every million invested. Subsequent to the original syndication deal, we reached an agreement permitting Galt to bifurcate their selection between two projects, the SS &lt;div style="font-style:italic;display:inline;;font-style:italic;display:inline;"&gt;Gairsoppa&lt;/div&gt; and HMS &lt;div style="font-style:italic;display:inline;;font-style:italic;display:inline;"&gt;Victory&lt;/div&gt; with the residual 1% on additional net proceeds assigned to the HMS &lt;div style="font-style:italic;display:inline;;font-style:italic;display:inline;"&gt;Victory&lt;/div&gt; project only. The bifurcation resulted in $3,756,250 being allocated to each of the two projects. Therefore, Galt will receive 7.5125% of net proceeds from the HMS &lt;div style="font-style:italic;display:inline;;font-style:italic;display:inline;"&gt;Victory&lt;/div&gt; project after they recoup their investment of $3,756,250 plus three times the investment. Galt has been paid in full for their share of the &lt;div style="font-style:italic;display:inline;;font-style:italic;display:inline;"&gt;Gairsoppa &lt;/div&gt;project investment. There are no future payments remaining due to Galt for the &lt;div style="font-style:italic;display:inline;;font-style:italic;display:inline;"&gt;Gairsoppa&lt;/div&gt; project. Based on the timing of the proceeds earmarked for Galt, the relative corresponding amount of Galt&amp;#8217;s revenue participation right of $3,756,250 was amortized into revenue in 2012 based upon the percent of Galt-related proceeds from the sale of silver as a percentage of total proceeds that Galt earned under the revenue participation agreement ($15.0 million). There is no expiration date on the Galt deal for the HMS &lt;div style="font-style:italic;display:inline;;font-style:italic;display:inline;"&gt;Victory&lt;/div&gt; project. If the archaeological excavation of the shipwreck is performed and insufficient proceeds are obtained, then the deferred income balance will be recognized as other income. If the archaeological excavation of the shipwreck is performed and sufficient proceeds are obtained, then the deferred income balance will be recognized as revenue. &lt;/div&gt;&lt;/div&gt;&lt;table border="0" style="width:100%; table-layout:fixed;" cellspacing="0" cellpadding="0"&gt;&lt;tr&gt;&lt;td&gt;&lt;/td&gt;&lt;/tr&gt;&lt;/table&gt;</us-gaap:RevenueFromContractWithCustomerTextBlock>

The financial statements and notes are representations of the Company&amp;#8217;s management who are responsible for their integrity and objectivity and have prepared them in accordance with our customary accounting practices. &lt;/div&gt;&lt;/div&gt;&lt;div style="font-family: times new roman; font-size: 10pt; margin-top: 18pt; margin-bottom: 0pt;"&gt;&lt;div style="font-family: &amp;quot;times new roman&amp;quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;"&gt;&lt;div style="font-weight:bold;display:inline;"&gt;Recent Accounting Pronouncements &lt;/div&gt;&lt;/div&gt;&lt;/div&gt;&lt;div style="font-family: times new roman; font-size: 10pt; margin-top: 6pt; margin-bottom: 0pt;"&gt;&lt;div style="font-family: &amp;quot;times new roman&amp;quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;"&gt;&lt;div style="font-weight:bold;display:inline;"&gt;&lt;div style="font-style:italic;display:inline;;font-style:italic;display:inline;"&gt;Accounting standards not yet applied &lt;/div&gt;&lt;/div&gt;&lt;/div&gt;&lt;/div&gt;&lt;div style="text-indent: 9%; font-family: times new roman; font-size: 10pt; margin-top: 6pt; margin-bottom: 0pt;"&gt;In August 2020, the FASB issued Accounting Standards Update (ASU) &lt;div style="white-space: nowrap; letter-spacing: 0px; top: 0px;;display:inline;"&gt;No.&amp;#160;2020-06,&lt;/div&gt; Debt-Debt with Conversion and Other Options (Subtopic &lt;div style="white-space: nowrap; letter-spacing: 0px; top: 0px;;display:inline;"&gt;470-20)&lt;/div&gt; and Derivatives and Hedging-Contracts in Entity&amp;#8217;s Own Equity (Subtopic &lt;div style="white-space: nowrap; letter-spacing: 0px; top: 0px;;display:inline;"&gt;815-40).&lt;/div&gt; The amendments in this Update are effective for public business entities that meet the definition of a Securities and Exchange Commission (SEC) filer, excluding entities eligible to be smaller reporting companies as defined by the SEC, for fiscal years beginning after December&amp;#160;15, 2021, including interim periods within those fiscal years. For all other entities, the amendments are effective for fiscal years beginning after December&amp;#160;15, 2023, including interim periods within those fiscal years. Early adoption is permitted, but no earlier than fiscal years beginning after December&amp;#160;15, 2020, including interim periods within those fiscal years. The Board specified that an entity should adopt the guidance as of the beginning of its annual fiscal year. &lt;/div&gt;&lt;div style="text-indent: 9%; font-family: times new roman; font-size: 10pt; margin-top: 12pt; margin-bottom: 0pt;"&gt;&lt;div style="font-family: &amp;quot;times new roman&amp;quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;"&gt;The amendments in the above Update affect entities that issue convertible instruments and/or contracts in an entity&amp;#8217;s own equity. For convertible instruments, the instruments primarily affected are those issued with beneficial conversion features or cash conversion features because the accounting models for those specific features are removed. However, all entities that issue convertible instruments are affected by the amendments to the disclosure requirements in this Update. For contracts in an entity&amp;#8217;s own equity, the contracts primarily affected are freestanding instruments and embedded features that are accounted for as derivatives under the current guidance because of failure to meet the settlement conditions of the derivatives scope exception related to certain requirements of the settlement assessment. The Board simplified the settlement assessment by removing the requirements (1)&amp;#160;to consider whether the contract would be settled in registered shares, (2)&amp;#160;to consider whether collateral is required to be posted, and (3)&amp;#160;to assess shareholder rights. Those amendments also affect the assessment of whether an embedded conversion feature in a convertible instrument qualifies for the derivatives scope exception. Additionally, the amendments in this Update affect the diluted EPS calculation for instruments that may be settled in cash or shares and for convertible instruments. The Company has not elected early adoption of this ASU. &lt;/div&gt;&lt;/div&gt;&lt;div style="text-indent: 9%; font-family: times new roman; font-size: 10pt; margin-top: 12pt; margin-bottom: 0pt;"&gt;On October 31, 2018, the SEC adopted a final rule (&amp;#8220;New Final Rule&amp;#8221;) that will replace SEC&amp;#160;Industry&amp;#160;Guide&amp;#160;7&amp;#160;with new disclosure requirements that are more closely aligned with current industry and global regulatory practices and standards, including NI &lt;div style="white-space: nowrap; letter-spacing: 0px; top: 0px;;display:inline;"&gt;43-101.&lt;/div&gt; Companies must comply with the New Final Rule for the company&amp;#8217;s first fiscal year beginning on or after January&amp;#160;1, 2021. While early voluntary compliance with the New Final Rule is permitted, we have not elected early adoption of this New Final Rule at this time. &lt;/div&gt;&lt;div style="text-indent: 9%; font-family: times new roman; font-size: 10pt; margin-top: 12pt; margin-bottom: 0pt;"&gt;&lt;div style="font-family: &amp;quot;times new roman&amp;quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;"&gt;Other recent accounting pronouncements issued by the FASB, the AICPA and the SEC did not or are not believed by management to have a material effect, if any, on the Company&amp;#8217;s financial statements. &lt;/div&gt;&lt;/div&gt;&lt;div style="font-family: times new roman; font-size: 10pt; margin-top: 18pt; margin-bottom: 0pt;"&gt;&lt;div style="font-family: &amp;quot;times new roman&amp;quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;"&gt;&lt;div style="font-weight:bold;display:inline;"&gt;Principles of Consolidation &lt;/div&gt;&lt;/div&gt;&lt;/div&gt;&lt;div style="text-indent: 9%; font-family: times new roman; font-size: 10pt; margin-top: 6pt; margin-bottom: 0pt;"&gt;The consolidated financial statements include the accounts of the Company and its direct and indirect wholly owned subsidiaries, both domestic and international. Equity investments in which we exercise significant influence but do not control and of which we are not the primary beneficiary are accounted for using the equity method. All significant inter-company and intra-company transactions and balances have been eliminated. The results of operations attributable to the &lt;div style="white-space: nowrap; letter-spacing: 0px; top: 0px;;display:inline;"&gt;non-controlling&lt;/div&gt; interest are presented within equity and net income and are shown separately from the Company&amp;#8217;s equity and net income attributable to the Company. Some of the existing inter-company balances, which are eliminated upon consolidation, include features allowing the liability to be converted into equity of a subsidiary, which if exercised, could increase the direct or indirect interest of the Company in the &lt;div style="white-space: nowrap; letter-spacing: 0px; top: 0px;;display:inline;"&gt;non-wholly&lt;/div&gt; owned subsidiaries. &lt;/div&gt;&lt;div style="font-family: times new roman; font-size: 10pt; margin-top: 18pt; margin-bottom: 0pt;"&gt;&lt;div style="font-family: &amp;quot;times new roman&amp;quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;"&gt;&lt;div style="font-weight:bold;display:inline;"&gt;Use of Estimates &lt;/div&gt;&lt;/div&gt;&lt;/div&gt;&lt;div style="text-indent: 9%; font-family: times new roman; font-size: 10pt; margin-top: 6pt; margin-bottom: 0pt;"&gt;&lt;div style="font-family: &amp;quot;times new roman&amp;quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;"&gt;Management uses estimates and assumptions in preparing these consolidated financial statements in accordance with U.S. GAAP. Those estimates and assumptions affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities, and the reported revenues and expenses. Actual results could vary from the estimates that were used. &lt;/div&gt;&lt;/div&gt;&lt;div style="font-family: times new roman; font-size: 10pt; margin-top: 18pt; margin-bottom: 0pt;"&gt;&lt;div style="font-family: &amp;quot;times new roman&amp;quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;"&gt;&lt;div style="font-weight:bold;display:inline;"&gt;Revenue Recognition and Accounts Receivable &lt;/div&gt;&lt;/div&gt;&lt;/div&gt;&lt;div style="text-indent: 9%; font-family: times new roman; font-size: 10pt; margin-top: 6pt; margin-bottom: 0pt;"&gt;As of January&amp;#160;1, 2019, the Company adopted the Financial Accounting Standards Board (FASB) Accounting Standards Update &lt;div style="white-space: nowrap; letter-spacing: 0px; top: 0px;;display:inline;"&gt;No.&amp;#160;2014-09,&lt;/div&gt; Revenue from Contracts with Customers (Topic 606), as modified (ASU &lt;div style="white-space: nowrap; letter-spacing: 0px; top: 0px;;display:inline;"&gt;No.&amp;#160;2014-09),&lt;/div&gt; using the modified retrospective method. This method requires that any financial statement impact from adoption be recognized as a cumulative adjustment to retained earnings as of the date of adoption. The adoption of this ASU did not change the timing of the Company&amp;#8217;s revenue recognition for any contracts and, therefore, the adoption of this standard did not have a material impact on the Company&amp;#8217;s financial statements. &lt;/div&gt;&lt;div style="text-indent: 9%; font-family: times new roman; font-size: 10pt; margin-top: 12pt; margin-bottom: 0pt;"&gt;&lt;div style="font-family: &amp;quot;times new roman&amp;quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;"&gt;Revenue is recognized when a customer obtains control of promised goods or services, in an amount that reflects the consideration which the Company expects to receive in exchange for those goods or services. To determine revenue recognition for arrangements that the Company determines are within the scope of ASC Topic 606, the Company performs the following five steps: (i)&amp;#160;identify the contract(s) with a customer; (ii)&amp;#160;identify the performance obligations in the contract; (iii)&amp;#160;determine the transaction price; (iv)&amp;#160;allocate the transaction price to the performance obligations in the contract; and (v)&amp;#160;recognize revenue when (or as) the Company satisfies a performance obligation. The Company only applies the five-step model to contracts when it is probable that the Company will collect the consideration it is entitled to in exchange for the goods or services it transfers to the customer. At contract inception, once the contract is determined to be within the scope of ASC Topic 606, the Company assesses the goods or services promised within each contract and determines those that are performance obligations and assesses whether each promised good or service is distinct. The Company then recognizes as revenue the amount of the transaction price that is allocated to the respective performance obligation when (or as) the performance obligation is satisfied. Sales, value add, and other taxes collected on behalf of third parties are excluded from revenue. &lt;/div&gt;&lt;/div&gt;&lt;div style="text-indent: 9%; font-family: times new roman; font-size: 10pt; margin-top: 12pt; margin-bottom: 0pt;"&gt;&lt;div style="font-family: &amp;quot;times new roman&amp;quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;"&gt;The Company currently generates revenues from four customers with contracts. There are two sources of revenue, marine services, and other services. The contracts for both services provide research, scientific services, marine operations planning, management execution, and project management. These services are billed generally on a monthly basis and recognized as revenue as the services are performed. Revenue is recognized at a point in time as services are provided, as the customers simultaneously receive and consume the benefits provided by the Company each month. The Company generally does not receive any upfront consideration for these services, and there is no variable consideration for the services.&amp;#160;Costs associated with both services include all direct consulting labor, and minimal supplies, and is charged to operations as a component of Operations and Research. &lt;/div&gt;&lt;/div&gt;&lt;div style="text-indent: 9%; font-family: times new roman; font-size: 10pt; margin-top: 12pt; margin-bottom: 0pt;"&gt;&lt;div style="font-family: &amp;quot;times new roman&amp;quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;"&gt;Accounts receivable are based on amounts billed to customers. Generally accepted accounting principles state an estimate is to be made for an allowance for doubtful accounts. We have determined no allowance is currently necessary. If we were to have a recorded allowance, the accounts receivable would be stated net of the recorded allowance. &lt;/div&gt;&lt;/div&gt;&lt;div style="font-family: times new roman; font-size: 10pt; margin-top: 18pt; margin-bottom: 0pt;"&gt;&lt;div style="font-family: &amp;quot;times new roman&amp;quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;"&gt;&lt;div style="font-weight:bold;display:inline;"&gt;Cash and Cash Equivalents &lt;/div&gt;&lt;/div&gt;&lt;/div&gt;&lt;div style="text-indent: 9%; font-family: times new roman; font-size: 10pt; margin-top: 6pt; margin-bottom: 0pt;"&gt;&lt;div style="font-family: &amp;quot;times new roman&amp;quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;"&gt;Cash and cash equivalents and restricted cash include cash on hand and cash in banks. We also consider all highly liquid investments with a maturity of three months or less when purchased to be cash equivalents, of which we do not have any. &lt;/div&gt;&lt;/div&gt;&lt;div style="font-family: times new roman; font-size: 10pt; margin-top: 18pt; margin-bottom: 0pt;"&gt;&lt;div style="font-family: &amp;quot;times new roman&amp;quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;"&gt;&lt;div style="font-weight:bold;display:inline;"&gt;Exploration License &lt;/div&gt;&lt;/div&gt;&lt;/div&gt;&lt;div style="text-indent: 9%; font-family: times new roman; font-size: 10pt; margin-top: 6pt; margin-bottom: 0pt;"&gt;&lt;div style="font-family: &amp;quot;times new roman&amp;quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;"&gt;The Company follows the guidance pursuant to ASU 350, &amp;#8220;&lt;div style="font-style:italic;display:inline;;font-style:italic;display:inline;"&gt;Intangibles-Goodwill and Other&lt;/div&gt;&amp;#8221; in accounting for its Exploration License. Management determined the rights to use the license to have an indefinite life. This assessment is based on the historical success of renewing the license since 2006, and the fact that management believes there are no legal, regulatory, or contractual provisions that would limit the useful life of the asset. The exploration license is not dependent on another asset or group of assets that could potentially limit the useful life of the exploration license. In the future, the recoverability of the license will be tested whenever circumstances indicate that its carrying amount may not recoverable per the guidance of the Accounting Standards Codification (&amp;#8220;ASC&amp;#8221;) for topic 360 for Property, Plant and Equipment&lt;div style="font-style:italic;display:inline;;font-style:italic;display:inline;"&gt;.&lt;/div&gt; &lt;/div&gt;&lt;/div&gt;&lt;div style="font-family: times new roman; font-size: 10pt; margin-top: 18pt; margin-bottom: 0pt;"&gt;&lt;div style="font-family: &amp;quot;times new roman&amp;quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;"&gt;&lt;div style="font-weight:bold;display:inline;"&gt;Long-Lived Assets &lt;/div&gt;&lt;/div&gt;&lt;/div&gt;&lt;div style="text-indent: 9%; font-family: times new roman; font-size: 10pt; margin-top: 6pt; margin-bottom: 0pt;"&gt;&lt;div style="font-family: &amp;quot;times new roman&amp;quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;"&gt;Our policy is to recognize impairment losses relating to long-lived assets in accordance with the ASC 360 Property, Plant and Equipment. Decisions are based on several factors, including, but not limited to, management&amp;#8217;s plans for future operations, recent operating results and projected cash flows. Impairment losses are included in depreciation at the time of impairment. We did not have any impairments in 2020, 2019 or 2018. &lt;/div&gt;&lt;/div&gt;&lt;div style="font-family: times new roman; font-size: 10pt; margin-top: 18pt; margin-bottom: 0pt;"&gt;&lt;div style="font-family: &amp;quot;times new roman&amp;quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;"&gt;&lt;div style="font-weight:bold;display:inline;"&gt;Property and Equipment and Depreciation &lt;/div&gt;&lt;/div&gt;&lt;/div&gt;&lt;div style="text-indent: 9%; font-family: times new roman; font-size: 10pt; margin-top: 6pt; margin-bottom: 0pt;"&gt;&lt;div style="font-family: &amp;quot;times new roman&amp;quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;"&gt;Property and equipment is stated at historical cost. Depreciation is calculated using the straight-line method at rates based on the assets&amp;#8217; estimated useful lives which are normally between three and thirty years. Leasehold improvements are amortized over their estimated useful lives or lease term, if shorter. Items that may require major overhauls (such as engines or generators) that enhance or extend the useful life of vessel related assets qualify to be capitalized and depreciated over the useful life or remaining life of that asset, whichever was shorter. Certain major repair items required by industry standards to ensure a vessel&amp;#8217;s seaworthiness also qualified to be capitalized and depreciated over the period of time until the next scheduled planned major maintenance for that item. All other repairs and maintenance were accounted for under the direct-expensing method and are expensed when incurred. &lt;/div&gt;&lt;/div&gt;&lt;div style="font-family: times new roman; font-size: 10pt; margin-top: 18pt; margin-bottom: 0pt;"&gt;&lt;div style="font-family: &amp;quot;times new roman&amp;quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;"&gt;&lt;div style="font-weight:bold;display:inline;"&gt;Earnings Per Share &lt;/div&gt;&lt;/div&gt;&lt;/div&gt;&lt;div style="text-indent: 9%; font-family: times new roman; font-size: 10pt; margin-top: 6pt; margin-bottom: 0pt;"&gt;Basic earnings per share (&amp;#8220;EPS&amp;#8221;) is computed by dividing income available to common stockholders by the weighted-average number of common shares outstanding for the period. In periods when the Company has income, the Company would calculate basic earnings per share using the &lt;div style="white-space: nowrap; letter-spacing: 0px; top: 0px;;display:inline;"&gt;two-class&lt;/div&gt; method, if required, pursuant to ASC 260 &lt;div style="font-style:italic;display:inline;;font-style:italic;display:inline;"&gt;Earnings Per Share.&lt;/div&gt; The &lt;div style="white-space: nowrap; letter-spacing: 0px; top: 0px;;display:inline;"&gt;two-class&lt;/div&gt; method was required effective with the issuance of certain senior convertible notes in the past because these notes qualified as a participating security, giving the holder the right to receive dividends should dividends be declared on common stock. Under the &lt;div style="white-space: nowrap; letter-spacing: 0px; top: 0px;;display:inline;"&gt;two-class&lt;/div&gt; method, earnings for a period are allocated on a pro rata basis to the common stockholders and to the holders of convertible notes based on the weighted average number of common shares outstanding and number of shares that could be issued upon conversion. The Company does not use the &lt;div style="white-space: nowrap; letter-spacing: 0px; top: 0px;;display:inline;"&gt;two-class&lt;/div&gt; method in periods when it generates a loss because the holder of the convertible notes does not participate in losses. Currently, we do not have any outstanding convertible notes that qualify as a participating security. &lt;/div&gt;&lt;div style="text-indent: 9%; font-family: times new roman; font-size: 10pt; margin-top: 12pt; margin-bottom: 0pt;"&gt;Diluted EPS reflects the potential dilution that would occur if dilutive securities and other contracts to issue common stock were exercised or converted into common stock or resulted in the issuance of common stock that then shared in our earnings. We use the treasury stock method to compute potential common shares from stock options and warrants and the &lt;div style="white-space: nowrap; letter-spacing: 0px; top: 0px;;display:inline;"&gt;if-converted&lt;/div&gt; method to compute potential common shares from preferred stock, convertible notes or other convertible securities. For diluted earnings per share, the Company uses the more dilutive of the &lt;div style="white-space: nowrap; letter-spacing: 0px; top: 0px;;display:inline;"&gt;if-converted&lt;/div&gt; method or &lt;div style="white-space: nowrap; letter-spacing: 0px; top: 0px;;display:inline;"&gt;two-class&lt;/div&gt; method. When a net loss occurs, potential common shares have an anti-dilutive effect on earnings per share and such shares are excluded from the diluted EPS calculation. &lt;/div&gt;&lt;div style="text-indent: 9%; font-family: times new roman; font-size: 10pt; margin-top: 12pt; margin-bottom: 0pt;"&gt;&lt;div style="font-family: &amp;quot;times new roman&amp;quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;"&gt;At December&amp;#160;31, 2020, 2019 and 2018 the weighted average common shares outstanding were 10,538,114, 9,346,213 and 8,583,795, respectively. For the periods ending December&amp;#160;31, 2020, 2019 and 2018 in which net losses occurred, all potential common shares were excluded from Diluted EPS because the effect of including such shares would be anti-dilutive. &lt;/div&gt;&lt;/div&gt;&lt;div style="text-indent: 9%; font-family: times new roman; font-size: 10pt; margin-top: 12pt; margin-bottom: 0pt;"&gt;&lt;div style="font-family: &amp;quot;times new roman&amp;quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;"&gt;The potential common shares, in the table following, represent potential common shares calculated using the treasury stock method from outstanding options and warrants that were excluded from the calculation of Diluted EPS: &lt;/div&gt;&lt;/div&gt;&lt;div style="font-size: 12pt;

Accordingly, our financial instruments consist of cash and cash equivalents, accounts receivable, accounts payable, accrued liabilities, derivative financial instruments and mortgage and loans payable. We carry cash and cash equivalents, accounts payable and accrued liabilities, and mortgage and loans payable at the approximate fair market value, and, accordingly, these estimates are not necessarily indicative of the amounts that we could realize in a current market exchange. We carry derivative financial instruments at fair value as is required under current accounting standards. &lt;/div&gt;&lt;/div&gt;&lt;div style="text-indent: 9%; font-family: times new roman; font-size: 10pt; margin-top: 12pt; margin-bottom: 0pt;"&gt;Derivative financial instruments consist of financial instruments or other contracts that contain a notional amount and one or more underlying variables (e.g., interest rate, security price or other variable), require no initial net investment and permit net settlement. Derivative financial instruments may be free-standing or embedded in other financial instruments. Further, derivative financial instruments are initially, and subsequently, measured at fair value and recorded as liabilities or, in rare instances, assets. We generally do not use derivative financial instruments to hedge exposures to cash-flow, market or foreign-currency risks. However, we have entered into certain other financial instruments and contracts with features that are either (i)&amp;#160;not afforded equity classification, (ii)&amp;#160;embody risks not clearly and closely related to host contracts, or (iii)&amp;#160;may be &lt;div style="white-space: nowrap; letter-spacing: 0px; top: 0px;;display:inline;"&gt;net-cash&lt;/div&gt; settled by the counterparty. As required by ASC 815 &amp;#8211; &lt;div style="font-style:italic;display:inline;;font-style:italic;display:inline;"&gt;Derivatives and Hedging&lt;/div&gt;, these instruments are required to be carried as derivative liabilities, at fair value, in our financial statements with changes in fair value reflected in our income. &lt;/div&gt;&lt;div style="text-indent: 9%; font-family: times new roman; font-size: 10pt; margin-top: 12pt; margin-bottom: 0pt;"&gt;&lt;div style="font-family: &amp;quot;times new roman&amp;quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;"&gt;We adopted ASC Topic 820 for certain financial instruments measured as fair value on a recurring basis. ASC Topic 820 defines fair value, established a framework for measuring fair value in accordance with accounting principles generally accepted in the United States and expands disclosures about fair value measurements. Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. ASC Topic 820 established a three-tier fair value hierarchy which prioritizes the inputs used in measuring fair value. &lt;/div&gt;&lt;/div&gt;&lt;div style="text-indent: 9%; font-family: times new roman; font-size: 10pt; margin-top: 12pt; margin-bottom: 0pt;"&gt;&lt;div style="font-family: &amp;quot;times new roman&amp;quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;"&gt;The hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (level 1 measurements) and the lowest priority to unobservable inputs (level 3 measurements). These tiers include: &lt;/div&gt;&lt;/div&gt;&lt;div style="font-family: times new roman; font-size: 10pt; margin-top: 18pt; margin-bottom: 0pt;"&gt;&lt;div style="font-family: &amp;quot;times new roman&amp;quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;"&gt;&lt;div style="font-style:italic;display:inline;;font-style:italic;display:inline;"&gt;Fair Value Hierarchy &lt;/div&gt;&lt;/div&gt;&lt;/div&gt;&lt;div style="text-indent: 9%; font-family: times new roman; font-size: 10pt; margin-top: 6pt; margin-bottom: 0pt;"&gt;&lt;div style="font-family: &amp;quot;times new roman&amp;quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;"&gt;The three levels of inputs that may be used to measure fair value are as follows: &lt;/div&gt;&lt;/div&gt;&lt;div style="text-indent: 9%; font-family: times new roman; font-size: 10pt; margin-top: 12pt; margin-bottom: 0pt;"&gt;&lt;div style="font-family: &amp;quot;times new roman&amp;quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;"&gt;&lt;div style="font-style:italic;display:inline;;font-style:italic;display:inline;"&gt;Level&lt;/div&gt;&lt;div style="font-style:italic;display:inline;;font-style:italic;display:inline;"&gt;&amp;#160;1.&lt;/div&gt;&lt;div style="font-style:italic;display:inline;;font-style:italic;display:inline;"&gt;&amp;#160;&lt;/div&gt;Quoted prices in active markets for identical assets or liabilities. &lt;/div&gt;&lt;/div&gt;&lt;div style="text-indent: 9%; font-family: times new roman; font-size: 10pt; margin-top: 12pt; margin-bottom: 0pt;"&gt;&lt;div style="font-style:italic;display:inline;;font-style:italic;display:inline;"&gt;Level&lt;/div&gt;&lt;div style="font-style:italic;display:inline;;font-style:italic;display:inline;"&gt;&amp;#160;2.&lt;/div&gt;&lt;div style="font-style:italic;display:inline;;font-style:italic;display:inline;"&gt;&amp;#160;&lt;/div&gt;Observable inputs other than Level&amp;#160;1 prices, such as quoted prices for similar assets or liabilities, quoted prices in markets with insufficient volume or infrequent transactions (less active markets), or model-derived valuations in which all significant inputs are observable or can be derived principally from or corroborated with observable market data for substantially the full term of the assets or liabilities. Level&amp;#160;2 inputs also include &lt;div style="white-space: nowrap; letter-spacing: 0px; top: 0px;;display:inline;"&gt;non-binding&lt;/div&gt; market consensus prices that can be corroborated with observable market data, as well as quoted prices that were adjusted for security-specific restrictions. &lt;/div&gt;&lt;div style="text-indent: 9%; font-family: times new roman; font-size: 10pt; margin-top: 12pt; margin-bottom: 0pt;"&gt;&lt;div style="font-style:italic;display:inline;;font-style:italic;display:inline;"&gt;Level&lt;/div&gt;&lt;div style="font-style:italic;display:inline;;font-style:italic;display:inline;"&gt;&amp;#160;3.&lt;/div&gt;&lt;div style="font-style:italic;display:inline;;font-style:italic;display:inline;"&gt;&amp;#160;&lt;/div&gt;Unobservable inputs to the valuation methodology are significant to the measurement of the fair value of assets or liabilities. Level&amp;#160;3 inputs also include &lt;div style="white-space: nowrap; letter-spacing: 0px; top: 0px;;display:inline;"&gt;non-binding&lt;/div&gt; market consensus prices or &lt;div style="white-space: nowrap; letter-spacing: 0px; top: 0px;;display:inline;"&gt;non-binding&lt;/div&gt; broker quotes that we were unable to corroborate with observable market data. &lt;/div&gt;&lt;div style="font-family: times new roman; font-size: 10pt; margin-top: 12pt; margin-bottom: 0pt;"&gt;&lt;div style="font-family: &amp;quot;times new roman&amp;quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;"&gt;We measure certain financial instruments at fair value on a recurring basis.

(NMI) &lt;/div&gt;&lt;/div&gt;&lt;/div&gt;&lt;/div&gt;&lt;div style="text-indent: 9%; font-family: times new roman; font-size: 10pt; margin-top: 6pt; margin-bottom: 0pt;"&gt;Our current investment in NMI consists of 3,092,488 Class&amp;#160;B Common &lt;div style="white-space: nowrap; letter-spacing: 0px; top: 0px;;display:inline;"&gt;non-voting&lt;/div&gt; shares and 2,612 Series A Preferred &lt;div style="white-space: nowrap; letter-spacing: 0px; top: 0px;;display:inline;"&gt;non-voting&lt;/div&gt; shares. These preferred shares are convertible into an aggregate of 261,200 shares of Class&amp;#160;B &lt;div style="white-space: nowrap; letter-spacing: 0px; top: 0px;;display:inline;"&gt;non-voting&lt;/div&gt; common stock. Our holdings now constitute an approximate 14% ownership in NMI. At December&amp;#160;31, 2020, our estimated share of unrecognized NMI equity-method losses is approximately $21.3&amp;#160;million. We have not recognized the accumulated $21.3&amp;#160;million in our income statement because these losses exceeded our investment in NMI. Our investment has a carrying value of zero as a result of the recognition of our share of prior losses incurred by NMI under the equity method of accounting. We believe it is appropriate to allocate this loss carryforward of $21.3&amp;#160;million to any incremental NMI investment that may be recognized on our balance sheet in excess of zero since the losses occurred when they were an equity-method investment. The aforementioned loss carryforward is based on NMI&amp;#8217;s last unaudited financial statements as of December&amp;#160;31, 2016. We do not believe losses NMI may have incurred subsequent to the December&amp;#160;31, 2016 audit to be material. We do not have any financial obligations to NMI, and we are not committed to provide financial support to NMI. &lt;/div&gt;&lt;div style="text-indent: 9%; font-family: times new roman; font-size: 10pt; margin-top: 12pt; margin-bottom: 0pt;"&gt;&lt;div style="font-family: &amp;quot;times new roman&amp;quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;"&gt;Although we are a shareholder of NMI, we have no representation on the board of directors or in management of NMI and do not hold any Class&amp;#160;A voting shares. We are not involved in the management of NMI nor do we participate in their policy-making. Accordingly, we are not the primary beneficiary of NMI. As of December&amp;#160;31, 2020, the net carrying value of our investment in NMI was zero in our consolidated financial statements. &lt;/div&gt;&lt;/div&gt;&lt;div style="font-family: times new roman; font-size: 10pt; margin-top: 18pt; margin-bottom: 0pt;"&gt;&lt;div style="font-family: &amp;quot;times new roman&amp;quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;"&gt;&lt;div style="font-weight:bold;display:inline;"&gt;&lt;div style="font-style:italic;display:inline;;font-style:italic;display:inline;"&gt;Chatham Rock Phosphate, Limited. &lt;/div&gt;&lt;/div&gt;&lt;/div&gt;&lt;/div&gt;&lt;div style="text-indent: 9%; font-family: times new roman; font-size: 10pt; margin-top: 6pt; margin-bottom: 0pt;"&gt;During 2012, we performed &lt;div style="white-space: nowrap; letter-spacing: 0px; top: 0px;;display:inline;"&gt;deep-sea&lt;/div&gt; mining exploratory services for Chatham Rock Phosphate, Ltd. (&amp;#8220;CRP&amp;#8221;) valued at $1,680,000. As payment for these services, CRP issued 9,320,348 ordinary shares to us. During March 2017, Antipodes Gold Limited completed the acquisition of CRP. The surviving entity is now named Chatham Rock Phosphate Limited (&amp;#8220;CRPL&amp;#8221;). In exchange for our 9,320,348 shares of CRP we received 141,884 shares of CPRL, which represents equity ownership of, at most, approximately 1% of the surviving entity. Since CRP was a thinly traded stock and pursuant to guidance per ASC 320: &lt;div style="font-style:italic;display:inline;;font-style:italic;display:inline;"&gt;Debt and Equity Securities&lt;/div&gt; regarding readily determinable fair value, we believe it was appropriate to not recognize this amount as an asset nor as revenue during that period. We continue to carry the value of our investment in CPRL at zero in our consolidated financial statements. &lt;/div&gt;&lt;div style="font-family: times new roman; font-size: 10pt; margin-top: 18pt; margin-bottom: 0pt;"&gt;&lt;div style="font-family: &amp;quot;times new roman&amp;quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;"&gt;&lt;div style="font-weight:bold;display:inline;"&gt;&lt;div style="font-style:italic;display:inline;;font-style:italic;display:inline;"&gt;CIC, LLC &lt;/div&gt;&lt;/div&gt;&lt;/div&gt;&lt;/div&gt;&lt;div style="text-indent: 9%; font-family: times new roman; font-size: 10pt; margin-top: 6pt; margin-bottom: 0pt;"&gt;&lt;div style="font-family: &amp;quot;times new roman&amp;quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;"&gt;In 2018, we began providing services to CIC LLC, a company controlled by Greg Stemm, the past Chairman of the Board for Odyssey (See NOTE J for related parties). This company is pursuing deep water mining permits in foreign waters. Due to the initial structure of the company, we determined this venture to be a VIE consistent with ASU 2015-2. We have determined that we are not the primary beneficiary of the VIE and, therefore, we have not consolidated this entity. Additionally, we also will record the investment under the cost method as we have determined we do not exercise significant influence over the entity. We will assess our investment for impairment annually and, if a loss in value is deemed other than temporary, an impairment charge will be recorded. At December&amp;#160;31, 2020, the accumulated investment in the entity is $2,370,794, which is classified as an investment in unconsolidated entity in our consolidated balance sheets. The original agreements relating to the equity investment were executed in January 2019. The original agreement was replaced in August of 2020 with a new agreement effective August&amp;#160;1, 2020. &lt;/div&gt;&lt;/div&gt;&lt;div style="text-indent: 9%; font-family: times new roman; font-size: 10pt; margin-top: 12pt; margin-bottom: 0pt;"&gt;&lt;div style="font-family: &amp;quot;times new roman&amp;quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;"&gt;We account for the investments we make in certain legal entities in which equity investors do not have (1)&amp;#160;sufficient equity at risk for the legal entity to finance its activities without additional subordinated financial support, or (2)&amp;#160;as a group, the holders of the equity investment at risk do not have either the power, through voting or similar rights, to direct the activities of the legal entity that most significantly impact the entity&amp;#8217;s economic performance, or (3)&amp;#160;the obligation to absorb the expected losses of the legal entity or the right to receive expected residual returns of the legal entity. These legal entities are referred to as &amp;#8220;variable interest entities&amp;#8221; or &amp;#8220;VIEs.&amp;#8221; &lt;/div&gt;&lt;/div&gt;&lt;div style="text-indent: 9%; font-family: times new roman; font-size: 10pt; margin-top: 12pt; margin-bottom: 0pt;"&gt;&lt;div style="font-family: &amp;quot;times new roman&amp;quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;"&gt;We would consolidate the results of any such entity in which we determined we had a controlling financial interest. We would have a &amp;#8220;controlling financial interest&amp;#8221; in such an entity if we had both the power to direct the activities that most significantly affect the VIE&amp;#8217;s economic performance and the obligation to absorb the losses of, or right to receive benefits from, the VIE that could be potentially significant to the VIE. On a quarterly basis, we reassess whether we have a controlling financial interest in any investments we have in these legal entities. &lt;/div&gt;&lt;/div&gt;&lt;div style="font-size: 1px; margin-top: 12px; margin-bottom: 0px;"&gt;&lt;div style="font-size: 1px; letter-spacing: 0px; top: 0px;;display:inline;"&gt;&amp;#160;&lt;/div&gt;&lt;/div&gt;&lt;div style="text-indent: 9%; font-family: times new roman; font-size: 10pt; margin-top: 0pt; margin-bottom: 0pt;"&gt;&lt;div style="font-family: &amp;quot;times new roman&amp;quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;"&gt;We determine whether any of the entities in which we have made investments is a VIE at the start of each new venture and if a reconsideration event has occurred. At such times, we also consider whether we must consolidate a VIE and/or disclose information about our involvement in a VIE. A reporting entity must consolidate a VIE if that reporting entity has a variable interest (or combination of variable interests) that will absorb a majority of the VIE&amp;#8217;s expected losses, receive a majority of the VIE&amp;#8217;s expected residual returns, or both. A reporting entity must consider the rights and obligations conveyed by its variable interests and the relationship of its variable interests with variable interests held by other parties to determine whether its variable interests will absorb a majority of a VIE&amp;#8217;s expected losses, receive a majority of the VIE&amp;#8217;s expected residual returns, or both. The reporting entity that consolidates a VIE is called the primary beneficiary of that VIE. &lt;/div&gt;&lt;/div&gt;&lt;table border="0" style="width:100%; table-layout:fixed;" cellspacing="0" cellpadding="0"&gt;&lt;tr&gt;&lt;td&gt;&lt;/td&gt;&lt;/tr&gt;&lt;/table&gt;</us-gaap:EquityMethodInvestmentsDisclosureTextBlock>

For all other entities, the amendments are effective for fiscal years beginning after December&amp;#160;15, 2023, including interim periods within those fiscal years. Early adoption is permitted, but no earlier than fiscal years beginning after December&amp;#160;15, 2020, including interim periods within those fiscal years. The Board specified that an entity should adopt the guidance as of the beginning of its annual fiscal year. &lt;/div&gt;&lt;div style="text-indent: 9%; font-family: times new roman; font-size: 10pt; margin-top: 12pt; margin-bottom: 0pt;"&gt;&lt;div style="font-family: &amp;quot;times new roman&amp;quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;"&gt;The amendments in the above Update affect entities that issue convertible instruments and/or contracts in an entity&amp;#8217;s own equity. For convertible instruments, the instruments primarily affected are those issued with beneficial conversion features or cash conversion features because the accounting models for those specific features are removed. However, all entities that issue convertible instruments are affected by the amendments to the disclosure requirements in this Update. For contracts in an entity&amp;#8217;s own equity, the contracts primarily affected are freestanding instruments and embedded features that are accounted for as derivatives under the current guidance because of failure to meet the settlement conditions of the derivatives scope exception related to certain requirements of the settlement assessment. The Board simplified the settlement assessment by removing the requirements (1)&amp;#160;to consider whether the contract would be settled in registered shares, (2)&amp;#160;to consider whether collateral is required to be posted, and (3)&amp;#160;to assess shareholder rights. Those amendments also affect the assessment of whether an embedded conversion feature in a convertible instrument qualifies for the derivatives scope exception. Additionally, the amendments in this Update affect the diluted EPS calculation for instruments that may be settled in cash or shares and for convertible instruments. The Company has not elected early adoption of this ASU. &lt;/div&gt;&lt;/div&gt;&lt;div style="text-indent: 9%; font-family: times new roman; font-size: 10pt; margin-top: 12pt; margin-bottom: 0pt;"&gt;On October 31, 2018, the SEC adopted a final rule (&amp;#8220;New Final Rule&amp;#8221;) that will replace SEC&amp;#160;Industry&amp;#160;Guide&amp;#160;7&amp;#160;with new disclosure requirements that are more closely aligned with current industry and global regulatory practices and standards, including NI &lt;div style="white-space: nowrap; letter-spacing: 0px; top: 0px;;display:inline;"&gt;43-101.&lt;/div&gt; Companies must comply with the New Final Rule for the company&amp;#8217;s first fiscal year beginning on or after January&amp;#160;1, 2021. While early voluntary compliance with the New Final Rule is permitted, we have not elected early adoption of this New Final Rule at this time. &lt;/div&gt;&lt;div style="text-indent: 9%; font-family: times new roman; font-size: 10pt; margin-top: 12pt; margin-bottom: 0pt;"&gt;&lt;div style="font-family: &amp;quot;times new roman&amp;quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;"&gt;Other recent accounting pronouncements issued by the FASB, the AICPA and the SEC did not or are not believed by management to have a material effect, if any, on the Company&amp;#8217;s financial statements. &lt;/div&gt;&lt;/div&gt;&lt;table border="0" style="width:100%; table-layout:fixed;" cellspacing="0" cellpadding="0"&gt;&lt;tr&gt;&lt;td&gt;&lt;/td&gt;&lt;/tr&gt;&lt;/table&gt;</us-gaap:NewAccountingPronouncementsPolicyPolicyTextBlock>

This method requires that any financial statement impact from adoption be recognized as a cumulative adjustment to retained earnings as of the date of adoption. The adoption of this ASU did not change the timing of the Company&amp;#8217;s revenue recognition for any contracts and, therefore, the adoption of this standard did not have a material impact on the Company&amp;#8217;s financial statements. &lt;/div&gt;&lt;div style="text-indent: 9%; font-family: times new roman; font-size: 10pt; margin-top: 12pt; margin-bottom: 0pt;"&gt;&lt;div style="font-family: &amp;quot;times new roman&amp;quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;"&gt;Revenue is recognized when a customer obtains control of promised goods or services, in an amount that reflects the consideration which the Company expects to receive in exchange for those goods or services. To determine revenue recognition for arrangements that the Company determines are within the scope of ASC Topic 606, the Company performs the following five steps: (i)&amp;#160;identify the contract(s) with a customer; (ii)&amp;#160;identify the performance obligations in the contract; (iii)&amp;#160;determine the transaction price; (iv)&amp;#160;allocate the transaction price to the performance obligations in the contract; and (v)&amp;#160;recognize revenue when (or as) the Company satisfies a performance obligation. The Company only applies the five-step model to contracts when it is probable that the Company will collect the consideration it is entitled to in exchange for the goods or services it transfers to the customer. At contract inception, once the contract is determined to be within the scope of ASC Topic 606, the Company assesses the goods or services promised within each contract and determines those that are performance obligations and assesses whether each promised good or service is distinct. The Company then recognizes as revenue the amount of the transaction price that is allocated to the respective performance obligation when (or as) the performance obligation is satisfied. Sales, value add, and other taxes collected on behalf of third parties are excluded from revenue. &lt;/div&gt;&lt;/div&gt;&lt;div style="text-indent: 9%; font-family: times new roman; font-size: 10pt; margin-top: 12pt; margin-bottom: 0pt;"&gt;&lt;div style="font-family: &amp;quot;times new roman&amp;quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;"&gt;The Company currently generates revenues from four customers with contracts. There are two sources of revenue, marine services, and other services. The contracts for both services provide research, scientific services, marine operations planning, management execution, and project management. These services are billed generally on a monthly basis and recognized as revenue as the services are performed. Revenue is recognized at a point in time as services are provided, as the customers simultaneously receive and consume the benefits provided by the Company each month. The Company generally does not receive any upfront consideration for these services, and there is no variable consideration for the services.&amp;#160;Costs associated with both services include all direct consulting labor, and minimal supplies, and is charged to operations as a component of Operations and Research. &lt;/div&gt;&lt;/div&gt;&lt;div style="text-indent: 9%; font-family: times new roman; font-size: 10pt; margin-top: 12pt; margin-bottom: 0pt;"&gt;&lt;div style="font-family: &amp;quot;times new roman&amp;quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;"&gt;Accounts receivable are based on amounts billed to customers. Generally accepted accounting principles state an estimate is to be made for an allowance for doubtful accounts. We have determined no allowance is currently necessary. If we were to have a recorded allowance, the accounts receivable would be stated net of the recorded allowance. &lt;/div&gt;&lt;/div&gt;&lt;table border="0" style="width:100%; table-layout:fixed;" cellspacing="0" cellpadding="0"&gt;&lt;tr&gt;&lt;td&gt;&lt;/td&gt;&lt;/tr&gt;&lt;/table&gt;</us-gaap:RevenueRecognitionPolicyTextBlock>

Management determined the rights to use the license to have an indefinite life. This assessment is based on the historical success of renewing the license since 2006, and the fact that management believes there are no legal, regulatory, or contractual provisions that would limit the useful life of the asset. The exploration license is not dependent on another asset or group of assets that could potentially limit the useful life of the exploration license. In the future, the recoverability of the license will be tested whenever circumstances indicate that its carrying amount may not recoverable per the guidance of the Accounting Standards Codification (&amp;#8220;ASC&amp;#8221;) for topic 360 for Property, Plant and Equipment&lt;div style="font-style:italic;display:inline;;font-style:italic;display:inline;"&gt;.&lt;/div&gt; &lt;/div&gt;&lt;/div&gt;&lt;table border="0" style="width:100%; table-layout:fixed;" cellspacing="0" cellpadding="0"&gt;&lt;tr&gt;&lt;td&gt;&lt;/td&gt;&lt;/tr&gt;&lt;/table&gt;</omex:ExplorationLicensesPolicyTextBlock>

Depreciation is calculated using the straight-line method at rates based on the assets&amp;#8217; estimated useful lives which are normally between three and thirty years. Leasehold improvements are amortized over their estimated useful lives or lease term, if shorter. Items that may require major overhauls (such as engines or generators) that enhance or extend the useful life of vessel related assets qualify to be capitalized and depreciated over the useful life or remaining life of that asset, whichever was shorter. Certain major repair items required by industry standards to ensure a vessel&amp;#8217;s seaworthiness also qualified to be capitalized and depreciated over the period of time until the next scheduled planned major maintenance for that item. All other repairs and maintenance were accounted for under the direct-expensing method and are expensed when incurred. &lt;/div&gt;&lt;/div&gt;&lt;table border="0" style="width:100%; table-layout:fixed;" cellspacing="0" cellpadding="0"&gt;&lt;tr&gt;&lt;td&gt;&lt;/td&gt;&lt;/tr&gt;&lt;/table&gt;</us-gaap:PropertyPlantAndEquipmentPolicyTextBlock>
<us-gaap:EarningsPerSharePolicyTextBlock id="Factid_19149734" contextRef="P01_01_2020To12_31_2020">&lt;div style="font-family: times new roman; font-size: 10pt; margin-top: 18pt; margin-bottom: 0pt;"&gt;&lt;div style="font-family: &amp;quot;times new roman&amp;quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;"&gt;&lt;div style="font-weight:bold;display:inline;"&gt;Earnings Per Share &lt;/div&gt;&lt;/div&gt;&lt;/div&gt;&lt;div style="text-indent: 9%; font-family: times new roman; font-size: 10pt; margin-top: 6pt; margin-bottom: 0pt;"&gt;Basic earnings per share (&amp;#8220;EPS&amp;#8221;) is computed by dividing income available to common stockholders by the weighted-average number of common shares outstanding for the period. In periods when the Company has income, the Company would calculate basic earnings per share using the &lt;div style="white-space: nowrap; letter-spacing: 0px; top: 0px;;display:inline;"&gt;two-class&lt;/div&gt; method, if required, pursuant to ASC 260 &lt;div style="font-style:italic;display:inline;;font-style:italic;display:inline;"&gt;Earnings Per Share.&lt;/div&gt; The &lt;div style="white-space: nowrap; letter-spacing: 0px; top: 0px;;display:inline;"&gt;two-class&lt;/div&gt; method was required effective with the issuance of certain senior convertible notes in the past because these notes qualified as a participating security, giving the holder the right to receive dividends should dividends be declared on common stock. Under the &lt;div style="white-space: nowrap; letter-spacing: 0px; top: 0px;;display:inline;"&gt;two-class&lt;/div&gt; method, earnings for a period are allocated on a pro rata basis to the common stockholders and to the holders of convertible notes based on the weighted average number of common shares outstanding and number of shares that could be issued upon conversion. The Company does not use the &lt;div style="white-space: nowrap; letter-spacing: 0px; top: 0px;;display:inline;"&gt;two-class&lt;/div&gt; method in periods when it generates a loss because the holder of the convertible notes does not participate in losses. Currently, we do not have any outstanding convertible notes that qualify as a participating security. &lt;/div&gt;&lt;div style="text-indent: 9%; font-family: times new roman; font-size: 10pt; margin-top: 12pt; margin-bottom: 0pt;"&gt;Diluted EPS reflects the potential dilution that would occur if dilutive securities and other contracts to issue common stock were exercised or converted into common stock or resulted in the issuance of common stock that then shared in our earnings. We use the treasury stock method to compute potential common shares from stock options and warrants and the &lt;div style="white-space: nowrap; letter-spacing: 0px; top: 0px;;display:inline;"&gt;if-converted&lt;/div&gt; method to compute potential common shares from preferred stock, convertible notes or other convertible securities. For diluted earnings per share, the Company uses the more dilutive of the &lt;div style="white-space: nowrap; letter-spacing: 0px; top: 0px;;display:inline;"&gt;if-converted&lt;/div&gt; method or &lt;div style="white-space: nowrap; letter-spacing: 0px; top: 0px;;display:inline;"&gt;two-class&lt;/div&gt; method. When a net loss occurs, potential common shares have an anti-dilutive effect on earnings per share and such shares are excluded from the diluted EPS calculation. &lt;/div&gt;&lt;div style="text-indent: 9%; font-family: times new roman; font-size: 10pt; margin-top: 12pt; margin-bottom: 0pt;"&gt;&lt;div style="font-family: &amp;quot;times new roman&amp;quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;"&gt;At December&amp;#160;31, 2020, 2019 and 2018 the weighted average common shares outstanding were 10,538,114, 9,346,213 and 8,583,795, respectively. For the periods ending December&amp;#160;31, 2020, 2019 and 2018 in which net losses occurred, all potential common shares were excluded from Diluted EPS because the effect of including such shares would be anti-dilutive. &lt;/div&gt;&lt;/div&gt;&lt;div style="text-indent: 9%;

Further, derivative financial instruments are initially, and subsequently, measured at fair value and recorded as liabilities or, in rare instances, assets. We generally do not use derivative financial instruments to hedge exposures to cash-flow, market or foreign-currency risks. However, we have entered into certain other financial instruments and contracts with features that are either (i)&amp;#160;not afforded equity classification, (ii)&amp;#160;embody risks not clearly and closely related to host contracts, or (iii)&amp;#160;may be &lt;div style="white-space: nowrap; letter-spacing: 0px; top: 0px;;display:inline;"&gt;net-cash&lt;/div&gt; settled by the counterparty. As required by ASC 815 &amp;#8211; &lt;div style="font-style:italic;display:inline;;font-style:italic;display:inline;"&gt;Derivatives and Hedging&lt;/div&gt;, these instruments are required to be carried as derivative liabilities, at fair value, in our financial statements with changes in fair value reflected in our income. &lt;/div&gt;&lt;div style="text-indent: 9%; font-family: times new roman; font-size: 10pt; margin-top: 12pt; margin-bottom: 0pt;"&gt;&lt;div style="font-family: &amp;quot;times new roman&amp;quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;"&gt;We adopted ASC Topic 820 for certain financial instruments measured as fair value on a recurring basis. ASC Topic 820 defines fair value, established a framework for measuring fair value in accordance with accounting principles generally accepted in the United States and expands disclosures about fair value measurements. Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. ASC Topic 820 established a three-tier fair value hierarchy which prioritizes the inputs used in measuring fair value. &lt;/div&gt;&lt;/div&gt;&lt;div style="text-indent: 9%; font-family: times new roman; font-size: 10pt; margin-top: 12pt; margin-bottom: 0pt;"&gt;&lt;div style="font-family: &amp;quot;times new roman&amp;quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;"&gt;The hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (level 1 measurements) and the lowest priority to unobservable inputs (level 3 measurements). These tiers include: &lt;/div&gt;&lt;/div&gt;&lt;div style="font-family: times new roman; font-size: 10pt; margin-top: 18pt; margin-bottom: 0pt;"&gt;&lt;div style="font-family: &amp;quot;times new roman&amp;quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;"&gt;&lt;div style="font-style:italic;display:inline;;font-style:italic;display:inline;"&gt;Fair Value Hierarchy &lt;/div&gt;&lt;/div&gt;&lt;/div&gt;&lt;div style="text-indent: 9%; font-family: times new roman; font-size: 10pt; margin-top: 6pt; margin-bottom: 0pt;"&gt;&lt;div style="font-family: &amp;quot;times new roman&amp;quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;"&gt;The three levels of inputs that may be used to measure fair value are as follows: &lt;/div&gt;&lt;/div&gt;&lt;div style="text-indent: 9%; font-family: times new roman; font-size: 10pt; margin-top: 12pt; margin-bottom: 0pt;"&gt;&lt;div style="font-family: &amp;quot;times new roman&amp;quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;"&gt;&lt;div style="font-style:italic;display:inline;;font-style:italic;display:inline;"&gt;Level&lt;/div&gt;&lt;div style="font-style:italic;display:inline;;font-style:italic;display:inline;"&gt;&amp;#160;1.&lt;/div&gt;&lt;div style="font-style:italic;display:inline;;font-style:italic;display:inline;"&gt;&amp;#160;&lt;/div&gt;Quoted prices in active markets for identical assets or liabilities. &lt;/div&gt;&lt;/div&gt;&lt;div style="text-indent: 9%; font-family: times new roman; font-size: 10pt; margin-top: 12pt; margin-bottom: 0pt;"&gt;&lt;div style="font-style:italic;display:inline;;font-style:italic;display:inline;"&gt;Level&lt;/div&gt;&lt;div style="font-style:italic;display:inline;;font-style:italic;display:inline;"&gt;&amp;#160;2.&lt;/div&gt;&lt;div style="font-style:italic;display:inline;;font-style:italic;display:inline;"&gt;&amp;#160;&lt;/div&gt;Observable inputs other than Level&amp;#160;1 prices, such as quoted prices for similar assets or liabilities, quoted prices in markets with insufficient volume or infrequent transactions (less active markets), or model-derived valuations in which all significant inputs are observable or can be derived principally from or corroborated with observable market data for substantially the full term of the assets or liabilities. Level&amp;#160;2 inputs also include &lt;div style="white-space: nowrap; letter-spacing: 0px; top: 0px;;display:inline;"&gt;non-binding&lt;/div&gt; market consensus prices that can be corroborated with observable market data, as well as quoted prices that were adjusted for security-specific restrictions. &lt;/div&gt;&lt;div style="text-indent: 9%; font-family: times new roman; font-size: 10pt; margin-top: 12pt; margin-bottom: 0pt;"&gt;&lt;div style="font-style:italic;display:inline;;font-style:italic;display:inline;"&gt;Level&lt;/div&gt;&lt;div style="font-style:italic;display:inline;;font-style:italic;display:inline;"&gt;&amp;#160;3.&lt;/div&gt;&lt;div style="font-style:italic;display:inline;;font-style:italic;display:inline;"&gt;&amp;#160;&lt;/div&gt;Unobservable inputs to the valuation methodology are significant to the measurement of the fair value of assets or liabilities.

font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;"&gt;On August&amp;#160;14, 2014, we entered into a Loan Agreement with Monaco Financial, LLC (&amp;#8220;Monaco&amp;#8221;), a strategic marketing partner, pursuant to which Monaco agreed to lend us up to $10.0&amp;#160;million. The loan was issued in three tranches: (i) $5.0&amp;#160;million (the &amp;#8220;First Tranche&amp;#8221;) was advanced upon execution of the Loan Agreement; (ii) $2.5&amp;#160;million (the &amp;#8220;Second Tranche&amp;#8221;) was advanced on October&amp;#160;1, 2014; and (iii) $2.5&amp;#160;million (the &amp;#8220;Third Tranche&amp;#8221;) was advanced on December&amp;#160;1, 2014. The Notes bear interest at a rate equal to 11% per annum. The Notes also contain an option whereby Monaco can purchase shares of Oceanica held by Odyssey (the &amp;#8220;Share Purchase Option&amp;#8221;) at a purchase price that is the lower of (a) $3.15 per share or (b)&amp;#160;the price per share of a contemplated equity offering of Oceanica which totals $1.0&amp;#160;million or more in the aggregate. The share purchase option was not clearly and closely related to the host debt agreement and required bifurcation. &lt;/div&gt;&lt;/div&gt;&lt;div style="text-indent: 9%; font-family: times new roman; font-size: 10pt; margin-top: 12pt; margin-bottom: 0pt;"&gt;On December&amp;#160;10, 2015, these promissory notes were amended as part of the asset acquisition agreement with Monaco (See NOTE R in our Form &lt;div style="white-space: nowrap; letter-spacing: 0px; top: 0px;;display:inline;"&gt;10-K&lt;/div&gt; filed with the Securities and Exchange Commission for the period ended December&amp;#160;31, 2017 for further information). The amendment included the following material changes: (i) $2.2&amp;#160;million of the indebtedness represented by the Notes was extinguished, (ii) $5.0&amp;#160;million of the indebtedness represented by the Notes ceased to bear interest and is only repayable under certain circumstances from certain sources of cash, and (iii)&amp;#160;the maturity date on the Notes was extended to December&amp;#160;31, 2017. During March 2016, the maturity date was further extended to April&amp;#160;1, 2018 and the exercise price of the Share Purchase Option was &lt;div style="white-space: nowrap; letter-spacing: 0px; top: 0px;;display:inline;"&gt;re-priced&lt;/div&gt; to $1.00 per share. This indebtedness has matured, but Monaco has not demanded payment because we are in negotiations with Monaco. As of the maturity date, the interest rate was adjusted to the default rate of 18% per annum. See &amp;#8220;Loan Modification (March 2016)&amp;#8221; below. For the twelve months ended December&amp;#160;31, 2020 and 2019, interest expense in the amount of $574,680 and $573,110, respectively, was recorded. The outstanding interest-bearing balance of these Notes is $2.8&amp;#160;million at December&amp;#160;31, 2020 and 2019. &lt;/div&gt;&lt;div style="font-family: &amp;quot;times new roman&amp;quot;; font-size: 10pt; margin-top: 18pt; margin-bottom: 0pt; line-height: 12pt;"&gt;&lt;div style="font-family: &amp;quot;times new roman&amp;quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;"&gt;&lt;div style="font-weight:bold;display:inline;"&gt;Note 2 &amp;#8211; Monaco 2016 &lt;/div&gt;&lt;/div&gt;&lt;/div&gt;&lt;div style="text-indent: 9%; font-family: times new roman; font-size: 10pt; margin-top: 6pt; margin-bottom: 0pt;"&gt;In March 2016, Monaco agreed to lend us an additional $1,825,000. These loan proceeds were received in full during the first quarter of 2016. The indebtedness bears interest at 10.0% percent per year. All principal and any unpaid interest was payable on April&amp;#160;15, 2018. This indebtedness has matured, but Monaco has not demanded payment because we are in negotiations with Monaco. As of the maturity date, the interest rate was adjusted to the default rate of 18% per annum. The current outstanding balance as of December&amp;#160;31, 2020 and 2019 was $1,175,000. The indebtedness is convertible at any time until the maturity date into shares of Oceanica held by us at a conversion price of $1.00 per share. Pursuant to this loan and as security for the indebtedness, Monaco was granted a second priority security interest in &lt;div style="white-space: nowrap; letter-spacing: 0px; top: 0px;;display:inline;"&gt;(a)&amp;#160;one-half&lt;/div&gt; of the indebtedness evidenced by the Amended and Restated Consolidated Note and Guaranty, dated September&amp;#160;25, 2015 (the &amp;#8220;ExO Note&amp;#8221;), in the original principal amount of $18.0&amp;#160;million, issued by Exploraciones Oceanicas S. de R.L. de C.V. to Oceanica Marine Operations, S.R.L. (&amp;#8220;OMO&amp;#8221;), and all rights associated therewith (the &amp;#8220;OMO Collateral&amp;#8221;); and (b)&amp;#160;all technology and assets in our possession or control used for offshore exploration, including an ROV system, &lt;div style="white-space: nowrap; letter-spacing: 0px; top: 0px;;display:inline;"&gt;deep-tow&lt;/div&gt; search systems, winches, multi-beam sonar, and other equipment. The carrying net book value of this equipment is less than $0.1&amp;#160;million. We unconditionally and irrevocably guaranteed all obligations of ours and our subsidiaries to Monaco under this loan agreement. As further consideration for the loan, Monaco was granted an option (the &amp;#8220;Option&amp;#8221;) to purchase the OMO Collateral. The Option is exercisable at any time before the earlier of (a)&amp;#160;the date that is 30 days after the loan is paid in full or (b)&amp;#160;the maturity date of the ExO Note, for aggregate consideration of $9.3&amp;#160;million, $1.8&amp;#160;million of which would be paid at the closing of the exercise of the Option, with the balance paid in ten monthly installments of $750,000. During 2017, we sold a marine vessel to a related party of Monaco for $650,000.&amp;#160;The consideration for this vessel was applied against our loan balance to Monaco in the amount of $650,000. &lt;/div&gt;&lt;div style="font-family: times new roman; font-size: 10pt; margin-top: 18pt; margin-bottom: 0pt;"&gt;&lt;div style="font-family: &amp;quot;times new roman&amp;quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;"&gt;&lt;div style="font-weight:bold;display:inline;"&gt;&lt;div style="font-style:italic;display:inline;;font-style:italic;display:inline;"&gt;Accounting considerations &lt;/div&gt;&lt;/div&gt;&lt;/div&gt;&lt;/div&gt;&lt;div style="text-indent: 9%; font-family: times new roman; font-size: 10pt; margin-top: 6pt; margin-bottom: 0pt;"&gt;&lt;div style="font-family: &amp;quot;times new roman&amp;quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;"&gt;ASC 815 generally requires the analysis of embedded terms and features that have characteristics of derivatives to be evaluated for bifurcation and separate accounting in instances where their economic risks and characteristics are not clearly and closely related to the risks of the host contract. The option to purchase the OMO Collateral is an embedded feature that is not clearly and closely related to the host debt agreement and thus requires bifurcation. Because the option is out of the money, it has no material fair value as of the inception date or currently. The debt agreement did not contain any additional embedded terms or features that have characteristics of derivatives. However, we were required to consider whether the hybrid contract embodied a beneficial conversion feature (&amp;#8220;BCF&amp;#8221;). The calculation of the effective conversion amount did result in a BCF because the effective conversion price was less than the market price on the date of issuance, therefore a BCF of $456,250 was recorded. This BCF has been fully amortized as of March&amp;#160;31, 2018. A total of $252,940 has been previously charged to interest expense related to the discount. For the twelve months ended December&amp;#160;31, 2020 and 2019, interest in the amount of $268,350 and $267,617, respectively, was recorded. &lt;/div&gt;&lt;/div&gt;&lt;div style="text-indent: 9%; font-family: times new roman; font-size: 10pt; margin-top: 18pt; margin-bottom: 0pt;"&gt;&lt;div style="font-family: &amp;quot;times new roman&amp;quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;"&gt;&lt;div style="font-weight:bold;display:inline;"&gt;&lt;div style="font-style:italic;display:inline;;font-style:italic;display:inline;"&gt;Loan modification (December 2015) &lt;/div&gt;&lt;/div&gt;&lt;/div&gt;&lt;/div&gt;&lt;div style="text-indent: 9%; font-family: times new roman; font-size: 10pt; margin-top: 6pt; margin-bottom: 0pt;"&gt;&lt;div style="font-family: &amp;quot;times new roman&amp;quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;"&gt;In connection with the Acquisition Agreement entered into with Monaco on December&amp;#160;10, 2015, Monaco agreed to modify certain terms of the loans as partial consideration for the purchase of assets. For the First Tranche ($5,000,000 advanced on August&amp;#160;14, 2014), Monaco agreed to cease interest as of December&amp;#160;10, 2015 and reduce the loan balance by (i)&amp;#160;the cash or other value received from the SS &lt;div style="font-style:italic;display:inline;;font-style:italic;display:inline;"&gt;Central America&lt;/div&gt; shipwreck project (&amp;#8220;SSCA&amp;#8221;) or (ii)&amp;#160;if the proceeds received from the SSCA project were insufficient to pay off the loan balance by December&amp;#160;31, 2017, then Monaco could seek repayment of the remaining outstanding balance on the loan by withholding Odyssey&amp;#8217;s 21.25% &amp;#8220;additional consideration&amp;#8221; in new shipwreck projects performed for Monaco in the future. For the Second Tranche ($2,500,000 advanced on October&amp;#160;1, 2014), Monaco agreed to reduce the principal amount by $2,200,000 leaving a new principal balance of $300,000 and extension of maturity to December&amp;#160;31, 2017. For the Third Tranche ($2,500,000 advanced on December&amp;#160;1, 2014), Monaco agreed to the extension of maturity to December&amp;#160;31, 2017. &lt;/div&gt;&lt;/div&gt;&lt;div style="text-indent: 9%; font-family: times new roman; font-size: 10pt; margin-top: 12pt; margin-bottom: 0pt;"&gt;&lt;div style="font-family: &amp;quot;times new roman&amp;quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;"&gt;On December&amp;#160;10, 2015, the Monaco call option related to the Oceanica shares held by us was extended until December&amp;#160;31, 2017. &lt;/div&gt;&lt;/div&gt;&lt;div style="text-indent: 9%; font-family: times new roman; font-size: 10pt; margin-top: 18pt; margin-bottom: 0pt;"&gt;&lt;div style="font-family: &amp;quot;times new roman&amp;quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;"&gt;&lt;div style="font-weight:bold;display:inline;"&gt;&lt;div style="font-style:italic;display:inline;;font-style:italic;display:inline;"&gt;Loan modification (March 2016) &lt;/div&gt;&lt;/div&gt;&lt;/div&gt;&lt;/div&gt;&lt;div style="text-indent: 9%; font-family: times new roman; font-size: 10pt; margin-top: 6pt; margin-bottom: 0pt;"&gt;In connection with the $1.825&amp;#160;million loan agreement with Monaco in March 2016, the existing $2.8&amp;#160;million notes were modified. Of the combined total indebtedness of Monaco&amp;#8217;s Note 1 and Note 2, Monaco can convert this debt into 3,174,603 shares of Oceanica at a fixed conversion price of $1.00 per share, or $3,174,603. Any remaining debt in excess of $3,174,603 is not convertible. Additionally, the modification eliminated Monaco&amp;#8217;s option (&amp;#8220;share purchase option&amp;#8221;) to purchase 3,174,603 shares of Oceanica stock at a price of $3.15 per share. The modification was analyzed under ASC 480 &lt;div style="font-style:italic;display:inline;;font-style:italic;display:inline;"&gt;Distinguishing Liabilities from Equity&lt;/div&gt; (&amp;#8220;ASC 480&amp;#8221;) to determine if extinguishment accounting was applicable. Under ASC &lt;div style="white-space: nowrap; letter-spacing: 0px; top: 0px;;display:inline;"&gt;&lt;div style="white-space: nowrap; letter-spacing: 0px; top: 0px;;display:inline;"&gt;&lt;div style="white-space: nowrap; letter-spacing: 0px; top: 0px;;display:inline;"&gt;470-50-40-10&lt;/div&gt;&lt;/div&gt;&lt;/div&gt; a modification or an exchange that adds or eliminates a substantive conversion option as of the conversion date is always considered substantial and requires extinguishment accounting. Since this modification added a substantive conversion option, extinguishment accounting is applicable. In accordance with the extinguishment accounting guidance (a)&amp;#160;the share purchase option was first marked to its &lt;div style="white-space: nowrap; letter-spacing: 0px; top: 0px;;display:inline;"&gt;pre-modification&lt;/div&gt; fair value, (b)&amp;#160;the new debt was recorded at fair value and (c)&amp;#160;the old debt and share purchased option was removed. The difference between the fair value of the new debt and the sum of the &lt;div style="white-space: nowrap; letter-spacing: 0px; top: 0px;;display:inline;"&gt;pre-modification&lt;/div&gt; carrying amount of the old debt and the share purchase option&amp;#8217;s fair value represented a gain on extinguishment. ASC &lt;div style="white-space: nowrap; letter-spacing: 0px; top: 0px;;display:inline;"&gt;&lt;div style="white-space: nowrap; letter-spacing: 0px; top: 0px;;display:inline;"&gt;&lt;div style="white-space: nowrap; letter-spacing: 0px; top: 0px;;display:inline;"&gt;470-50-40-2&lt;/div&gt;&lt;/div&gt;&lt;/div&gt; indicates that debt restructuring with a related party may be in essence a capital transaction and as a result the gain of $1.2&amp;#160;million was recognized in additional paid in capital upon extinguishment. &lt;/div&gt;&lt;table border="0" style="width:100%; table-layout:fixed;" cellspacing="0" cellpadding="0"&gt;&lt;tr&gt;&lt;td&gt;&lt;/td&gt;&lt;/tr&gt;&lt;/table&gt;&lt;div style="font-family: times new roman; font-size: 10pt; margin-top: 18pt; margin-bottom: 0pt;"&gt;&lt;div style="font-family: &amp;quot;times new roman&amp;quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;"&gt;&lt;div style="font-weight:bold;display:inline;"&gt;Note 3 &amp;#8211; MINOSA &lt;/div&gt;&lt;/div&gt;&lt;/div&gt;&lt;div style="text-indent: 9%; font-family: times new roman; font-size: 10pt; margin-top: 6pt; margin-bottom: 0pt;"&gt;&lt;div style="font-family: &amp;quot;times new roman&amp;quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;"&gt;On March&amp;#160;11, 2015, in connection with a Stock Purchase Agreement, Minera del Norte, S.A. de C.V. (&amp;#8220;MINOSA&amp;#8221;) agreed to lend us up to $14.75&amp;#160;million. The entire $14.75&amp;#160;million was loaned in five advances from March&amp;#160;11 through June&amp;#160;30, 2015. The outstanding indebtedness bears interest at 8.0% percent per annum. The Promissory Note was amended on April&amp;#160;10, 2015 and on October&amp;#160;1, 2015 so that, unless otherwise converted as provided in the Note, the adjusted principal balance shall be due and payable in full upon written demand by MINOSA; provided that MINOSA agreed that it shall not demand payment of the adjusted principal balance earlier than the first to occur of: (i)&amp;#160;30 days after the date on which (x)&amp;#160;SEMARNAT makes a determination with respect to the current application for the Manifestacion de Impacto Ambiental relating to phosphate deposit project, which determination is other than an approval or (y)&amp;#160;Odyssey Marine Enterprises or any of its affiliates withdraws such application without MINOSA&amp;#8217;s prior written consent; (ii)&amp;#160;termination by Odyssey of the Stock Purchase Agreement, dated March&amp;#160;11, 2015 (the &amp;#8220;Purchase Agreement&amp;#8221;), among Odyssey, MINOSA, and Penelope Mining, LLC (the &amp;#8220;Investor&amp;#8221;); (iii)&amp;#160;the occurrence of an event of default under the Promissory Note; (iv)&amp;#160;December 31, 2015; or (v)&amp;#160;if and only if the Investor shall have terminated the Purchase Agreement pursuant to Section&amp;#160;8.1(d)(iii) thereof, March&amp;#160;30, 2016. This indebtedness is classified as short-term debt. In connection with the loans, we granted MINOSA an option to purchase our 54% interest in Oceanica for $40.0&amp;#160;million (the &amp;#8220;Oceanica Call Option&amp;#8221;). On March&amp;#160;11, 2016, the Oceanica Call has expired. Completion of the transaction requires amending the Company&amp;#8217;s articles of incorporation to (a)&amp;#160;effect a reverse stock split, which was implemented on February&amp;#160;19, 2016, (b)&amp;#160;adjusting the Company&amp;#8217;s authorized capitalization, which was also implemented on February&amp;#160;19, 2016, and (c)&amp;#160;establishing a classified board of directors (collectively, the &amp;#8220;Amendments&amp;#8221;). The Amendments have been or will be set forth in certificates of amendment to the Company&amp;#8217;s articles of incorporation filed or to be filed with the Nevada Secretary of State. As collateral for the loan, we granted MINOSA a security interest in the Company&amp;#8217;s 54% interest in Oceanica. The outstanding principal balance of this debt was $14.75&amp;#160;million at December&amp;#160;31, 2020 and 2019, respectively. The maturity date of this indebtedness has been amended and matured on March&amp;#160;18, 2017. Per Note 6 MINOSA 2 below, the Minosa Purchase Agreement amended the due date of this note to a due date which may be no earlier than December&amp;#160;31, 2017, that is at least 60 days subsequent to written notice that Minosa intends to demand payment. See Note 6 &amp;#8211; MINOSA 2 for further qualifications. During December 2017, MINOSA transferred this debt to its parent company. For the twelve months ended December&amp;#160;31, 2020 and 2019, interest in the amount of $1,183,230 and $1,180,000, respectively, was recorded. &lt;/div&gt;&lt;/div&gt;&lt;div style="text-indent: 9%; font-family: times new roman; font-size: 10pt; margin-top: 18pt; margin-bottom: 0pt;"&gt;&lt;div style="font-family: &amp;quot;times new roman&amp;quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;"&gt;&lt;div style="font-weight:bold;display:inline;"&gt;&lt;div style="font-style:italic;display:inline;;font-style:italic;display:inline;"&gt;Accounting considerations &lt;/div&gt;&lt;/div&gt;&lt;/div&gt;&lt;/div&gt;&lt;div style="text-indent: 9%; font-family: times new roman; font-size: 10pt; margin-top: 6pt; margin-bottom: 0pt;"&gt;&lt;div style="font-family: &amp;quot;times new roman&amp;quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;"&gt;We have accounted for this transaction as a financing transaction, wherein the net proceeds received were allocated to the financial instruments issued. Prior to making the accounting allocation, we evaluated for proper classification under ASC 480 &lt;div style="font-style:italic;display:inline;;font-style:italic;display:inline;"&gt;Distinguishing Liabilities from Equity&lt;/div&gt; (&amp;#8220;ASC 480&amp;#8221;), ASC 815 &lt;div style="font-style:italic;display:inline;;font-style:italic;display:inline;"&gt;Derivatives and Hedging&lt;/div&gt; (&amp;#8220;ASC 815&amp;#8221;) and ASC 320 &lt;div style="font-style:italic;display:inline;;font-style:italic;display:inline;"&gt;Property, Plant and Equipment&lt;/div&gt; (&amp;#8220;ASC 320&amp;#8221;). &lt;/div&gt;&lt;/div&gt;&lt;div style="text-indent: 9%; font-family: times new roman; font-size: 10pt; margin-top: 12pt; margin-bottom: 0pt;"&gt;This debt agreement did not contain any embedded terms or features that have characteristics of derivatives. The Oceanica Call Option is considered a freestanding financial instrument because it is both (i)&amp;#160;legally detachable and (ii)&amp;#160;separately exercisable. The Oceanica Call Option did not fall under the guidance of ASC 480. Additionally, it did not meet the definition of a derivative under ASC 815 because the option has a fixed value of $40.0&amp;#160;million and does not contain an underlying variable which is indicative of a derivative. This instrument is considered an option contract for a sale of an asset. The guidance applied in this case is ASC &lt;div style="white-space: nowrap; letter-spacing: 0px; top: 0px;;display:inline;"&gt;360-20,&lt;/div&gt; which provides that in situations when a party lends funds to a seller and is given an option to buy the property at a certain date in the future, the loan shall be recorded at its present value using market interest rates and any excess of the proceeds over that amount credited to an option deposit account. If the option is exercised, the deposit shall be included as part of the sales proceeds; if not exercised, it shall be credited to income in the period in which the option lapses. &lt;/div&gt;&lt;div  style="font-size: 13.28px; margin-top: 0pt; margin-bottom: 17pt; line-height: 12pt;;-webkit-margin-before: 0em;-webkit-margin-after: 0em;;font-weight: normal;"&gt;&amp;#160;&lt;/div&gt;&lt;div style="text-indent: 9%; font-family: times new roman;

Pursuant to the Purchase Agreement, Epsilon loaned us $3.0&amp;#160;million in two installments of $1.5&amp;#160;million on March&amp;#160;31, 2016 and April&amp;#160;30, 2016. The indebtedness bears interest at a rate of 10% per annum and was due on March&amp;#160;18, 2017. We were also responsible for $50,000 of the lender&amp;#8217;s out of pocket costs. This amount is included in the loan balance. In pledge agreements related to the loans, we granted security interests to Epsilon in (a)&amp;#160;the 54&amp;#160;million cuotas (a unit of ownership under Panamanian law) of Oceanica Resources S. de R.L. (&amp;#8220;Oceanica&amp;#8221;) held by our wholly owned subsidiary, Odyssey Marine Enterprises, Ltd. (&amp;#8220;OME&amp;#8221;), (b)&amp;#160;all notes and other receivables from Oceanica and its subsidiary owed to the Odyssey Pledgors, and (c)&amp;#160;all of the outstanding equity in OME. Epsilon has the right to convert the outstanding indebtedness into shares of our common stock upon 75 days&amp;#8217; notice to us or upon a merger, consolidation, third party tender offer, or similar transaction relating to us at the conversion price of $5.00 per share, which represents the &lt;div style="white-space: nowrap; letter-spacing: 0px; top: 0px;;display:inline;"&gt;five-day&lt;/div&gt; volume-weighted average price of Odyssey&amp;#8217;s common stock for the five trading day period ending on March&amp;#160;17, 2016. On January&amp;#160;25, 2017, Epsilon provided notice to us that it would convert the initial $3.0&amp;#160;million plus accrued interest per the Restated Note Purchase Agreement at $5.00 per share in accordance with the terms of the agreement. The conversion and issuance of new shares was effective April&amp;#160;10, 2017 and included accrued interest of $302,274 for a total 670,455 shares. Upon the occurrence and during the continuance of an event of default, the conversion price was to be reduced to $2.50 per share. Following any conversion of the indebtedness, Penelope Mining LLC (an affiliate of Epsilon) (&amp;#8220;Penelope&amp;#8221;), may elect to reduce its commitment to purchase preferred stock of Odyssey under the Stock Purchase Agreement, dated as of March&amp;#160;11, 2015 (as amended, the &amp;#8220;Stock Purchase Agreement&amp;#8221;), among Odyssey, Penelope, and Minera del Norte, S.A. de C.V. (&amp;#8220;MINOSA&amp;#8221;) by the amount of indebtedness converted. &lt;/div&gt;&lt;div style="text-indent: 9%; font-family: times new roman; font-size: 10pt; margin-top: 12pt; margin-bottom: 0pt;"&gt;Pursuant to the Purchase Agreement (a)&amp;#160;we agreed to waive our rights to terminate the Stock Purchase Agreement in accordance with the terms thereof until December&amp;#160;31, 2016, and (b)&amp;#160;MINOSA agreed to extend, until March&amp;#160;18, 2017, the maturity date of the $14.75&amp;#160;million loan extended by MINOSA to OME pursuant to the Stock Purchase Agreement. The indebtedness may be accelerated upon the occurrence of specified events of default including (a)&amp;#160;OME&amp;#8217;s failure to pay any amount payable on the date due and payable; (b)&amp;#160;OME or we fail to perform or observe any term, covenant, or agreement in the Purchase Agreement or the related documents, subject to a &lt;div style="white-space: nowrap; letter-spacing: 0px; top: 0px;;display:inline;"&gt;five-day&lt;/div&gt; cure period;&amp;#160;(c)&amp;#160;an event of default or material breach by OME, us or any of our affiliates under any of the other loan documents shall have occurred and all grace periods, if any, applicable thereto shall have expired; (d)&amp;#160;the Stock Purchase Agreement shall have been terminated; (e)&amp;#160;specified dissolution, liquidation, insolvency, bankruptcy, reorganization, or similar cases or actions are commenced by or against OME or any of its subsidiaries, in specified circumstances unless dismissed or stayed within 60 days; (f)&amp;#160;the entry of judgment or award against OME or any of its subsidiaries in excess or $100,000; and (g)&amp;#160;a change in control (as defined in the Purchase Agreement) occurs. &lt;/div&gt;&lt;div style="text-indent: 9%; font-family: times new roman; font-size: 10pt; margin-top: 12pt; margin-bottom: 0pt;"&gt;&lt;div style="font-family: &amp;quot;times new roman&amp;quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;"&gt;In connection with the execution and delivery of the Purchase Agreement, we and Epsilon entered into a registration rights agreement pursuant to which we agreed to register new shares of our common stock with a formal registration statement with the Securities and Exchange Commission upon the conversion of the indebtedness. &lt;/div&gt;&lt;/div&gt;&lt;div style="text-indent: 9%; font-family: times new roman; font-size: 10pt; margin-top: 18pt; margin-bottom: 0pt;"&gt;&lt;div style="font-family: &amp;quot;times new roman&amp;quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;"&gt;&lt;div style="font-weight:bold;display:inline;"&gt;&lt;div style="font-style:italic;display:inline;;font-style:italic;display:inline;"&gt;Accounting considerations &lt;/div&gt;&lt;/div&gt;&lt;/div&gt;&lt;/div&gt;&lt;div style="text-indent: 9%; font-family: times new roman; font-size: 10pt; margin-top: 6pt; margin-bottom: 0pt;"&gt;&lt;div style="font-family: &amp;quot;times new roman&amp;quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;"&gt;We have accounted for this transaction as a financing transaction, wherein the net proceeds received were allocated to the financial instruments issued.

However, we were required to consider whether the hybrid contract embodied a beneficial conversion feature (&amp;#8220;BCF&amp;#8221;). The calculation of the effective conversion amount did result in a BCF because the effective conversion price was less than the Company&amp;#8217;s stock price on the date of issuance, therefore a BCF of $96,000 was recorded. The BCF represents a debt discount which was amortized over the life of the loan. &lt;/div&gt;&lt;/div&gt;&lt;div style="text-indent: 9%; font-family: times new roman; font-size: 10pt; margin-top: 18pt; margin-bottom: 0pt;"&gt;&lt;div style="font-family: &amp;quot;times new roman&amp;quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;"&gt;&lt;div style="font-weight:bold;display:inline;"&gt;&lt;div style="font-style:italic;display:inline;;font-style:italic;display:inline;"&gt;Loan modification (October 1, 2016) &lt;/div&gt;&lt;/div&gt;&lt;/div&gt;&lt;/div&gt;&lt;div style="text-indent: 9%; font-family: times new roman; font-size: 10pt; margin-top: 6pt; margin-bottom: 0pt;"&gt;On October&amp;#160;1, 2016 Odyssey Marine Enterprises, Ltd. (&amp;#8220;OME&amp;#8221;), entered into an Amended and Restated Note Purchase Agreement (the &amp;#8220;Restated Note Purchase Agreement&amp;#8221;) with Epsilon Acquisitions LLC (&amp;#8220;Epsilon&amp;#8221;). In connection with the existing $3.0&amp;#160;million loan agreement, Epsilon agreed to lend an additional $3.0&amp;#160;million evidenced by secured convertible promissory notes. The convertible promissory notes bear an interest rate of 10.0% per annum and are due and payable on March&amp;#160;18, 2017. Epsilon has the right to convert all amounts outstanding under the Restated Note into shares of our common stock upon 75 days&amp;#8217; notice to OME or upon a merger, consolidation, third party tender offer, or similar transaction relating to us at the applicable conversion price, which is (a)&amp;#160;$5.00 per share with respect to the $3.0&amp;#160;million already advanced under the Restated Note and (b)&amp;#160;with respect to additional advances under the Restated Note, the &lt;div style="white-space: nowrap; letter-spacing: 0px; top: 0px;;display:inline;"&gt;five-day&lt;/div&gt; volume-weighted average price of our common stock for the five trading day period ending on the trading day immediately prior to the date on which OME submits a borrowing notice for such advance. Notwithstanding anything herein to the contrary, we shall not issue any of our common stock upon conversion of any outstanding tranche (other than the first $3.0&amp;#160;million already advanced) under this Restated Note in excess of 1,388,769 shares of common stock.&amp;#160;The additional tranches were issued as follows: (a) $1,000,000 (&amp;#8220;Tranche 3&amp;#8221;) was issued on October&amp;#160;16, 2016 with a conversion price of $3.52 per share; (b) $1,000,000 (&amp;#8220;Tranche 4&amp;#8221;) was issued on November&amp;#160;15, 2016 with a conversion price of $4.19 per share; and (c) $1,000,000 (&amp;#8220;Tranche 5&amp;#8221;) was issued on December&amp;#160;15, 2016 with a conversion price of $4.13 per share. During 2017, Epsilon assigned Tranche 4 and 5 totaling $2,000,000 of this debt to MINOSA under the same terms as the original debt. See Note &amp;#8211; MINOSA 2 below for further detail. &lt;/div&gt;&lt;div style="text-indent: 9%; font-family: times new roman; font-size: 10pt; margin-top: 12pt; margin-bottom: 0pt;"&gt;As an inducement for the issuance of the additional $3.0&amp;#160;million of promissory notes, we also delivered to Epsilon a common stock purchase warrant (the &amp;#8220;Warrant&amp;#8221;) pursuant to which Epsilon has the right to purchase up to 120,000 shares of our common stock at an exercise price of $3.52 per share, which exercise price represents the &lt;div style="white-space: nowrap; letter-spacing: 0px; top: 0px;;display:inline;"&gt;five-day&lt;/div&gt; volume-weighted average price of our common stock for the five trading day period ending on the trading day immediately prior to the day on which the Warrant was issued. Epsilon may exercise the Warrant in whole or in part at any time during the period ending October&amp;#160;1, 2021. The Warrant includes a cashless exercise feature and provides that, if Epsilon is in default of its obligations to fund any advance pursuant to and in accordance with the Restated Note Purchase Agreement, then, thereafter, the maximum aggregate number of shares of common stock that may be purchased under the Warrant shall be the number determined by multiplying 120,000 by a fraction, (a)&amp;#160;the numerator of which is the aggregate principal amount of advances that have been extended to the OME by Epsilon pursuant to the Restated Note Purchase Agreement on or after the date of the Warrant and prior to the date of such failure and (b)&amp;#160;the denominator of which is $3.0&amp;#160;million. During November 2020, Epsilon opted to exercise this warrant using the cashless exercise feature. This exercise resulted in the issuance of 56,228 of our common shares and the forfeiture of the right to acquire the remaining 63,772 common shares. &lt;/div&gt;&lt;div style="text-indent: 9%; font-family: times new roman; font-size: 10pt; margin-top: 18pt; margin-bottom: 0pt;"&gt;&lt;div style="font-family: &amp;quot;times new roman&amp;quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;"&gt;&lt;div style="font-weight:bold;display:inline;"&gt;&lt;div style="font-style:italic;display:inline;;font-style:italic;display:inline;"&gt;Accounting considerations for additional tranches &lt;/div&gt;&lt;/div&gt;&lt;/div&gt;&lt;/div&gt;&lt;div style="text-indent: 9%; font-family: times new roman; font-size: 10pt; margin-top: 6pt; margin-bottom: 0pt;"&gt;&lt;div style="font-family: &amp;quot;times new roman&amp;quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;"&gt;We evaluated for proper classification under ASC 480 &lt;div style="font-style:italic;display:inline;;font-style:italic;display:inline;"&gt;Distinguishing Liabilities from Equity&lt;/div&gt; (&amp;#8220;ASC 480&amp;#8221;), ASC 815 &lt;div style="font-style:italic;display:inline;;font-style:italic;display:inline;"&gt;Derivatives and Hedging&lt;/div&gt; (&amp;#8220;ASC 815&amp;#8221;) and ASC 320 &lt;div style="font-style:italic;display:inline;;font-style:italic;display:inline;"&gt;Property, Plant and Equipment&lt;/div&gt; (&amp;#8220;ASC 320&amp;#8221;). This debt agreement did not contain any embedded terms or features that have characteristics of derivatives. Additionally, the warrant agreement did not contain any terms or features that would preclude equity classification. We were required to consider whether the hybrid contract embodied a beneficial conversion feature (&amp;#8220;BCF&amp;#8221;).

For the twelve months ended December&amp;#160;31, 2020 and 2019, interest in the amount of $90,136 and $100,272, respectively, was recorded. &lt;/div&gt;&lt;/div&gt;&lt;div style="font-size: 1px; margin-top: 18px; margin-bottom: 0px;"&gt;&lt;div style="font-size: 1px; letter-spacing: 0px; top: 0px;;display:inline;"&gt;&amp;#160;&lt;/div&gt;&lt;/div&gt;&lt;div style="text-indent: 9%; font-family: times new roman; font-size: 10pt; margin-top: 0pt; margin-bottom: 0pt;"&gt;&lt;div style="font-family: &amp;quot;times new roman&amp;quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;"&gt;&lt;div style="font-weight:bold;display:inline;"&gt;&lt;div style="font-style:italic;display:inline;;font-style:italic;display:inline;"&gt;Term Extension (March 21, 2017) &lt;/div&gt;&lt;/div&gt;&lt;/div&gt;&lt;/div&gt;&lt;div style="text-indent: 9%; font-family: times new roman; font-size: 10pt; margin-top: 6pt; margin-bottom: 0pt;"&gt;&lt;div style="font-family: &amp;quot;times new roman&amp;quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;"&gt;On March&amp;#160;21, 2017 we entered into an amendment to the Restated Note Purchase Agreement with Epsilon. In connection with the existing $6.0&amp;#160;million of indebtedness, the adjusted principal balance is due and payable in full upon the earlier of (i)&amp;#160;written demand by Epsilon or (ii)&amp;#160;such time as Odyssey or the guarantor pays any other indebtedness for borrowed money prior to its stated maturity date. As such the Company amortized the notes up to their face value of $6,050,000 and they are classified as short-term. However, since Epsilon converted the first $3.0&amp;#160;million into 670,455 of our common shares and assigned $2.0&amp;#160;million to MINOSA, the current principal indebtedness at December&amp;#160;31, 2020 and 2019 is $1.0&amp;#160;million. &lt;/div&gt;&lt;/div&gt;&lt;div style="font-family: times new roman; font-size: 10pt; margin-top: 18pt; margin-bottom: 0pt;"&gt;&lt;div style="font-family: &amp;quot;times new roman&amp;quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;"&gt;&lt;div style="font-weight:bold;display:inline;"&gt;Note 5 &amp;#8211; SMOM &lt;/div&gt;&lt;/div&gt;&lt;/div&gt;&lt;div style="text-indent: 9%; font-family: times new roman; font-size: 10pt; margin-top: 6pt; margin-bottom: 0pt;"&gt;&lt;div style="font-family: &amp;quot;times new roman&amp;quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;"&gt;On May&amp;#160;3, 2017, we entered into a Loan and Security Agreement (&amp;#8220;Loan Agreement&amp;#8221;) with SMOM. Pursuant to the Loan Agreement, SMOM agreed to loan us up to $3.0&amp;#160;million as evidenced by a convertible promissory note. As a commitment fee, we assigned the remaining 50% of our Neptune Minerals, LLC receivable to SMOM. This receivable had zero carrying value on our balance sheet and due to the age and collectability was deemed to have no fair value. The indebtedness bears interest at a rate of 10% per annum and matures on the second anniversary of this Loan Agreement which is May&amp;#160;3, 2019. During January 2020 this Loan Agreement was amended by increasing the interest rate to 18%. On April&amp;#160;20, 2018, the loan was amended, and the principal amount of the Loan was increased to $3,500,000. The loan balance at December&amp;#160;31, 2020 and 2019 is $3.5&amp;#160;million. The holder has the option to convert up to $2.0&amp;#160;million of any unpaid principal and interest into up to 50% of the equity interest held by Odyssey in Aldama Mining Company, S.de R.L. de C.V. which is a wholly owned subsidiary of ours. The conversion value of $1.0&amp;#160;million equates to 10% of the equity interest in Aldama. If the holder elects to acquire the entire 50% of the 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&amp;#160;million for each 10% of equity interests) during the period that is the later of (i)&amp;#160;one year after the maturity date and (ii)&amp;#160;one year after the loan is repaid in full, the expiration date. The lender may also choose to extend the expiration date annually by paying $500,000 for each year extended. For the twelve months ended December&amp;#160;31, 2020 and 2019, interest in the amount of $350,958 and $349,999, respectively, was recorded. &lt;/div&gt;&lt;/div&gt;&lt;div style="text-indent: 9%; font-family: times new roman; font-size: 10pt; margin-top: 18pt; margin-bottom: 0pt;"&gt;&lt;div style="font-family: &amp;quot;times new roman&amp;quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;"&gt;&lt;div style="font-weight:bold;display:inline;"&gt;&lt;div style="font-style:italic;display:inline;;font-style:italic;display:inline;"&gt;Accounting considerations &lt;/div&gt;&lt;/div&gt;&lt;/div&gt;&lt;/div&gt;&lt;div style="text-indent: 9%; font-family: times new roman; font-size: 10pt; margin-top: 6pt; margin-bottom: 0pt;"&gt;&lt;div style="font-family: &amp;quot;times new roman&amp;quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;"&gt;We have accounted for this transaction as a financing transaction, wherein the net proceeds received were allocated to the financial instruments issued. Prior to making the accounting allocation, we evaluated for proper classification under ASC 480 &lt;div style="font-style:italic;display:inline;;font-style:italic;display:inline;"&gt;Distinguishing Liabilities from Equity&lt;/div&gt; (&amp;#8220;ASC 480&amp;#8221;), ASC 815 &lt;div style="font-style:italic;display:inline;;font-style:italic;display:inline;"&gt;Derivatives and Hedging&lt;/div&gt; (&amp;#8220;ASC 815&amp;#8221;) and ASC 320 &lt;div style="font-style:italic;display:inline;;font-style:italic;display:inline;"&gt;Property, Plant and Equipment&lt;/div&gt; (&amp;#8220;ASC 320&amp;#8221;). &lt;/div&gt;&lt;/div&gt;&lt;div style="text-indent: 9%; font-family: times new roman; font-size: 10pt; margin-top: 12pt; margin-bottom: 0pt;"&gt;&lt;div style="font-family: &amp;quot;times new roman&amp;quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;"&gt;This debt agreement did not contain any embedded terms or features that have characteristics of derivatives. However, we were required to consider whether the hybrid contract embodied a beneficial conversion feature (&amp;#8220;BCF&amp;#8221;). The calculation of the effective conversion amount did not result in a BCF because the effective conversion price was equal to the Company&amp;#8217;s stock price on the date of issuance. &lt;/div&gt;&lt;/div&gt;&lt;div style="font-family: times new roman; font-size: 10pt; margin-top: 18pt; margin-bottom: 0pt;"&gt;&lt;div style="font-family: &amp;quot;times new roman&amp;quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;"&gt;&lt;div style="font-weight:bold;display:inline;"&gt;Note 6 &amp;#8211; MINOSA 2 &lt;/div&gt;&lt;/div&gt;&lt;/div&gt;&lt;div style="text-indent: 9%; font-family: times new roman; font-size: 10pt; margin-top: 6pt; margin-bottom: 0pt;"&gt;&lt;div style="font-family: &amp;quot;times new roman&amp;quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;"&gt;On August&amp;#160;10, 2017, we entered into a Note Purchase Agreement (the &amp;#8220;Minosa Purchase Agreement&amp;#8221;) with MINOSA. Pursuant to the Minosa Purchase Agreement, MINOSA agreed to loan Enterprises up to $3.0&amp;#160;million. During 2017, we borrowed $2.7&amp;#160;million against this facility and Epsilon assigned $2.0&amp;#160;million of its debt to MINOSA. At December&amp;#160;31, 2020 and 2019, the outstanding principal balance, including the Epsilon assignment, is $5.05&amp;#160;million. The indebtedness is evidenced by a secured convertible promissory note (the &amp;#8220;Minosa Note&amp;#8221;) and bears interest at a rate equal to 10.0%&amp;#160;per annum. Unless otherwise converted as described below, the entire outstanding principal balance under this Minosa Note and all accrued interest and fees are due and payable upon written demand by MINOSA; provided, that MINOSA agreed not make a demand for payment prior to the earlier of (a)&amp;#160;an event of default (as defined in the Minosa Note) or (b)&amp;#160;a date, which may be no earlier than December&amp;#160;31, 2017, that is at least 60 days subsequent to written notice that MINOSA intends to demand payment. MINOSA has not provided any notice they intend to issue a payment demand notice. We unconditionally and irrevocably guaranteed all of the obligations under the Minosa Purchase Agreement and the Minosa Note. MINOSA has the right to convert all amounts outstanding under the Minosa Note into shares of our common stock upon 75 days&amp;#8217; notice to us or upon a merger, consolidation, third party tender offer, or similar transaction relating to us at the conversion price of&amp;#160;$4.41 per share. During December 2017, MINOSA transferred this debt to its parent company. &lt;/div&gt;&lt;/div&gt;&lt;div style="font-size: 1px; margin-top: 12px; margin-bottom: 0px;"&gt;&lt;div style="font-size: 1px; letter-spacing: 0px; top: 0px;;display:inline;"&gt;&amp;#160;&lt;/div&gt;&lt;/div&gt;&lt;div style="text-indent: 9%; font-family: times new roman; font-size: 10pt; margin-top: 0pt; margin-bottom: 0pt;"&gt;&lt;div style="font-family: &amp;quot;times new roman&amp;quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;"&gt;This debt agreement did not contain any embedded terms or features that have characteristics of derivatives. However, we were required to consider whether the hybrid contract embodied a beneficial conversion feature (&amp;#8220;BCF&amp;#8221;). The calculation of the effective conversion amount did result in a BCF because the effective conversion price was less than the Company&amp;#8217;s stock price on the date of issuance, therefore a BCF of $62,925 was recorded. As of December&amp;#160;31, 2017, all of the BCF has been accreted to the income statement. The BCF represented a debt discount that was amortized over the life of the loan. For the twelve months ended December&amp;#160;31, 2020 and 2019, interest in the amount of $506,381 and $504,998, respectively, was recorded. &lt;/div&gt;&lt;/div&gt;&lt;div style="text-indent: 9%; font-family: times new roman; font-size: 10pt; margin-top: 12pt; margin-bottom: 0pt;"&gt;&lt;div style="font-family: &amp;quot;times new roman&amp;quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;"&gt;As previously reported, Epsilon loaned us an aggregate of $6.0&amp;#160;million pursuant to an amended and restated convertible promissory Minosa Note, dated as of March&amp;#160;18, 2016, as further amended and restated on October&amp;#160;1, 2016 (the &amp;#8220;Epsilon Note&amp;#8221;). Since then, Epsilon has assigned $2.0&amp;#160;million of the indebtedness under the Epsilon Note to MINOSA. Along with Epsilon, we entered into a second amended and restated convertible promissory note (the &amp;#8220;Second AR Epsilon Note&amp;#8221;), which further amends and restates the Epsilon Note. The stated principal amount of the Second AR Epsilon Note is $1.0&amp;#160;million (which reflects the outstanding principal balance remaining after giving effect to Epsilon&amp;#8217;s (x)&amp;#160;previous assignment of $2.0&amp;#160;million of the indebtedness under the Epsilon Note to MINOSA and (y)&amp;#160;conversion of $3.0&amp;#160;million of the indebtedness under the Epsilon Note into shares of our common stock). The Second AR Epsilon Note further provides that the outstanding principal balance under the Second AR Epsilon Note and all accrued interest and fees are due and payable upon written demand by Epsilon; provided, that Epsilon agreed not make a demand for payment prior to the earlier of (a)&amp;#160;an event of default (as defined in the Second AR Epsilon Note) or (b)&amp;#160;a date, which may be no earlier than December&amp;#160;31, 2017, that is at least 60 days subsequent to written notice that MINOSA intends to demand payment. &lt;/div&gt;&lt;/div&gt;&lt;div style="text-indent: 9%; font-family: times new roman; font-size: 10pt; margin-top: 12pt; margin-bottom: 0pt;"&gt;&lt;div style="font-family: &amp;quot;times new roman&amp;quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;"&gt;Upon the closing of the Minosa Purchase Agreement, along with MINOSA, and Penelope Mining LLC, an affiliate of Minosa (&amp;#8220;Penelope&amp;#8221;), executed and delivered a Second Amended and Restated Waiver and Consent and Amendment No.&amp;#160;5 to Promissory Note and Amendment No.&amp;#160;2 to Stock Purchase Agreement (the &amp;#8220;Second&amp;#160;AR Waiver&amp;#8221;). Pursuant to the Second&amp;#160;AR Waiver, Minosa and Penelope consented to the transactions contemplated by the Minosa Purchase Agreement and waived any breach of any representation or warranty and violation of any covenant in the Stock Purchase Agreement, dated as of March&amp;#160;11, 2015, as amended April&amp;#160;10, 2015 (the &amp;#8220;SPA&amp;#8221;), by and among us, Minosa, and Penelope, arising out of the Company&amp;#8217;s execution and delivery of the Minosa Purchase Agreement and the consummation of the transactions contemplated thereby. Pursuant to the Second&amp;#160;AR Waiver, we also waived, and agreed not to exercise our right to terminate the SPA pursuant to Section&amp;#160;8.1(c)(ii) thereto, both (a)&amp;#160;until after the earlier of (i)&amp;#160;July&amp;#160;1, 2018, (ii)&amp;#160;the date that MINOSA fails, refuses, or declines to fund (or otherwise does not fund) any subsequent loan under the Minosa Purchase Agreement and (iii)&amp;#160;demand is made for repayment of all or any part of the indebtedness outstanding under the Minosa Note, the Second AR Epsilon Note, or the Promissory Note, dated as of March&amp;#160;11, 2015, as amended (the &amp;#8220;SPA Note&amp;#8221;), in the principal amount of $14.75&amp;#160;million that was issued by us to MINOSA under the SPA, and&amp;#160;(b) unless on or prior to such termination, the Notes are paid in full. &lt;/div&gt;&lt;/div&gt;&lt;div style="text-indent: 9%; font-family: times new roman; font-size: 10pt; margin-top: 12pt; margin-bottom: 0pt;"&gt;&lt;div style="font-family: &amp;quot;times new roman&amp;quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;"&gt;The Second&amp;#160;AR Waiver (x)&amp;#160;further provides that following any conversion of the indebtedness evidenced by the Minosa Note, Penelope may elect to reduce its commitment to purchase our preferred stock under the SPA by the amount of indebtedness converted by MINOSA and (y)&amp;#160;amends the SPA Note to provide that the outstanding principal balance under the SPA Note and all accrued interest and fees are due and payable upon written demand by MINOSA; provided, that Minosa agreed not make a demand for payment prior to the earlier of (a)&amp;#160;an event of default (as defined in the Minosa Note) or (b)&amp;#160;a date, which may be no earlier than December&amp;#160;31, 2017, that is at least 60 days subsequent to written notice that Minosa intends to demand payment. &lt;/div&gt;&lt;/div&gt;&lt;div style="text-indent: 9%; font-family: times new roman; font-size: 10pt; margin-top: 12pt; margin-bottom: 0pt;"&gt;The obligations under the Minosa Note may be accelerated upon the occurrence of specified events of default including (a)&amp;#160;our failure to pay any amount payable under the Minosa Note on the date due and payable; (b)&amp;#160;our failure to perform or observe any term, covenant, or agreement in the Minosa Note or the related documents, subject to a &lt;div style="white-space: nowrap; letter-spacing: 0px; top: 0px;;display:inline;"&gt;five-day&lt;/div&gt; cure period;&amp;#160;(c)&amp;#160;the occurrence and expiration of all applicable grace periods, if any, of an event of default or material breach by us under any of the other loan documents; (d)&amp;#160;the termination of the SPA; (e)&amp;#160;commencement of certain specified dissolution, liquidation, insolvency, bankruptcy, reorganization, or similar cases or actions by or against us, in specified circumstances unless dismissed or stayed within 60 days; (f)&amp;#160;the entry of a judgment or award against us in excess of $100,000; and (g)&amp;#160;the occurrence of a change in control (as defined in the Minosa Note). &lt;/div&gt;&lt;div style="text-indent: 9%; font-family: times new roman; font-size: 10pt; margin-top: 12pt; margin-bottom: 0pt;"&gt;&lt;div style="font-family: &amp;quot;times new roman&amp;quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;"&gt;Pursuant to second amended and restated pledge agreements (the &amp;#8220;Second AR Pledge Agreements&amp;#8221;) entered into by us in favor of MINOSA, we pledged and granted security interests to MINOSA in (a)&amp;#160;the 54&amp;#160;million cuotas (a unit of ownership under Panamanian law) of Oceanica held by us, (b)&amp;#160;all notes and other receivables from Oceanica and its subsidiary owed to us, and (c)&amp;#160;all of the outstanding equity in our wholly owned subsidiary, Odyssey Marine Enterprises, Ltd. &lt;/div&gt;&lt;div style="font-size: 1px; letter-spacing: 0px; top: 0px;;display:inline;"&gt;&amp;#160;&lt;/div&gt;&lt;/div&gt;&lt;div style="text-indent: 9%; font-family: &amp;quot;times new roman&amp;quot;; font-size: 10pt; margin-top: 12pt; margin-bottom: 0pt; line-height: 12pt;"&gt;In connection with the execution and delivery of the Minosa Purchase Agreement, Odyssey and MINOSA entered into a second amended and restated registration rights agreement (the &amp;#8220;Second AR Registration Rights Agreement&amp;#8221;) pursuant to which Odyssey agreed to register the offer and sale of the shares (the &amp;#8220;Conversion Shares&amp;#8221;) of our common stock issuable upon the conversion of the indebtedness evidenced by the Minosa Note. Subject to specified limitations set forth in the Second AR Registration Rights Agreement, including that we are eligible to use Form &lt;div style="white-space: nowrap; letter-spacing: 0px; top: 0px;;display:inline;"&gt;S-3,&lt;/div&gt; the holder of the Minosa Note can require us to register the offer and sale of the Conversion Shares if the aggregate offering price thereof (before any underwriting discounts and commissions) is not less than $3.0&amp;#160;million. In addition, we agreed to file a registration statement relating to the offer and sale of the Conversion Shares on a continuous basis promptly (but in no event later than 60 days after) after the conversion of the Minosa Note into the Conversion Shares and to thereafter use its reasonable best efforts to have such registration statement declared effective by the Securities and Exchange Commission. &lt;/div&gt;&lt;div&gt;&amp;#160;&lt;/div&gt;&lt;div style="font-family: &amp;quot;times new roman&amp;quot;; font-size: 10pt; margin-top: 12pt; margin-bottom: 0pt; line-height: 12pt;"&gt;&lt;div style="font-family: &amp;quot;times new roman&amp;quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;"&gt;&lt;div style="font-weight:bold;display:inline;"&gt;Note 7 &amp;#8211; Monaco 2018 &lt;/div&gt;&lt;/div&gt;&lt;/div&gt;&lt;div style="text-indent: 9%; font-family: times new roman; font-size: 10pt; margin-top: 6pt; margin-bottom: 0pt;"&gt;&lt;div style="font-family: &amp;quot;times new roman&amp;quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;"&gt;During the period ended March&amp;#160;31, 2018, Monaco advanced us $1.0&amp;#160;million that was applied to a loan agreement that was executed on April&amp;#160;20, 2018. Monaco also agreed to treat $99,366 of back rent owed by us to Monaco as part of this loan resulting in an aggregate principal amount of $1,099,367 at December&amp;#160;31, 2020 and 2019. The indebtedness bears interest at 10.0% percent per year. During January 2020 this loan agreement was amended by increasing the interest rate to 18%. All principal and any unpaid interest is to be payable on the first anniversary of this agreement, April&amp;#160;20, 2019. This debt is secured by cash proceeds, if any, from our future shipwreck projects we have contracted with Magellan. As additional consideration, their share purchase option expiration date, as discussed in Note 1 &amp;#8211; Monaco 2014 and Note 2 &amp;#8211; Monaco 2016 above, has been extended from 30 days to seven months after the note becomes paid in full. For the twelve months ended December&amp;#160;31, 2020 and 2019, interest in the amount of $138,333 and $123,466, respectively, was recorded. &lt;/div&gt;&lt;/div&gt;&lt;div style="font-family: times new roman; font-size: 10pt; margin-top: 18pt; margin-bottom: 0pt;"&gt;&lt;div style="font-family: &amp;quot;times new roman&amp;quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;"&gt;&lt;div style="font-weight:bold;display:inline;"&gt;Note 8 &amp;#8211; Promissory note &lt;/div&gt;&lt;/div&gt;&lt;/div&gt;&lt;div style="text-indent: 9%; font-family: times new roman; font-size: 10pt; margin-top: 6pt; margin-bottom: 0pt;"&gt;&lt;div style="font-family: &amp;quot;times new roman&amp;quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;"&gt;On July&amp;#160;12, 2018, we entered into a Note and Warrant Purchase Agreement (the &amp;#8220;Purchase Agreement&amp;#8221;) with two individuals (the &amp;#8220;Lenders&amp;#8221;), one of whom holds in excess of 5.0% of our outstanding common stock. Pursuant to the Purchase Agreement, the Lenders agreed to lend an aggregate of $1,050,000 to us, which was advanced in three tranches on July&amp;#160;12, 2018, $500,000, August&amp;#160;17, 2018, $300,000 and October&amp;#160;4, 2018, $250,000. The indebtedness is evidenced by secured convertible promissory notes (the &amp;#8220;Notes&amp;#8221;) and bears interest at a rate equal to 8.0% per annum. Unless otherwise converted as described below, the entire outstanding principal balance under the Notes and all accrued interest and fees are due and payable on July&amp;#160;12, 2019. &lt;/div&gt;&lt;/div&gt;&lt;div style="text-indent: 9%; font-family: times new roman; font-size: 10pt; margin-top: 12pt; margin-bottom: 0pt;"&gt;&lt;div style="font-family: &amp;quot;times new roman&amp;quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;"&gt;At any time after to the first to occur of (a)&amp;#160;a sale by us of additional Notes or (b)&amp;#160;September 12, 2018, the Lenders have the right to convert all amounts outstanding under the Notes into either (x)&amp;#160;shares of our common stock at the conversion rate of $8.00 per share, (y)&amp;#160;$500,000 of the indebtedness owed by Exploraciones Oceanicas S. de R.

Prior to making the accounting allocation, we evaluated the transaction for proper classification under ASC 480 Distinguishing Liabilities from Equity (&amp;#8220;ASC 480&amp;#8221;), ASC 815 Derivatives and Hedging (&amp;#8220;ASC 815&amp;#8221;). &lt;/div&gt;&lt;div style="font-size: 1px; letter-spacing: 0px; top: 0px;;display:inline;"&gt;&amp;#160;&lt;/div&gt;&lt;/div&gt;&lt;div style="text-indent: 9%; font-family: &amp;quot;times new roman&amp;quot;; font-size: 10pt; margin-top: 12pt; margin-bottom: 0pt; line-height: 12pt;"&gt;&lt;div style="font-family: &amp;quot;times new roman&amp;quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;"&gt;We determined that the debt achieved conventional convertible status and that the equity conversion option was in the money at inception which required the calculation of a beneficial conversion feature (&amp;#8220;BCF&amp;#8221;). The fair value of the warrants and BCF component exceeded the amount of proceeds, therefore, they were limited to the cash proceeds of $1,050,000 at December&amp;#160;31, 2018. As a result, there was no value allocated to the debt at inception. The debt was being accreted to face value over its term using the effective interest method. The face value of this debt was $1.05&amp;#160;million at December&amp;#160;31, 2020 and 2019. For the twelve months ended December&amp;#160;31, 2020 and 2019, interest in the amount of $97,652 and $89,911, respectively, was recorded. &lt;/div&gt;&lt;/div&gt;&lt;div style="text-indent: 9%; font-family: times new roman; font-size: 10pt; margin-top: 18pt; margin-bottom: 0pt;"&gt;&lt;div style="font-family: &amp;quot;times new roman&amp;quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;"&gt;&lt;div style="font-weight:bold;display:inline;"&gt;&lt;div style="font-style:italic;display:inline;;font-style:italic;display:inline;"&gt;Term Extension (July 8, 2019) &lt;/div&gt;&lt;/div&gt;&lt;/div&gt;&lt;/div&gt;&lt;div style="text-indent: 4%; font-family: times new roman; font-size: 10pt; margin-top: 6pt; margin-bottom: 0pt;"&gt;&lt;div style="font-family: &amp;quot;times new roman&amp;quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;"&gt;On July&amp;#160;8, 2019, Odyssey and the Lenders entered into a Second Amendment to Note and Warrant Purchase Agreement and Note and Warrant Modification Agreement (the &amp;#8220;Second Amendment&amp;#8221;) pursuant to which certain terms and provisions of the Notes and Warrants were amended or otherwise modified.

margin-bottom: 0pt;"&gt;We evaluated the amendment&amp;#8217;s impact on the accounting for the Note in accordance with ASC &lt;div style="white-space: nowrap; letter-spacing: 0px; top: 0px;;display:inline;"&gt;&lt;div style="white-space: nowrap; letter-spacing: 0px; top: 0px;;display:inline;"&gt;&lt;div style="white-space: nowrap; letter-spacing: 0px; top: 0px;;display:inline;"&gt;470-50-40-6&lt;/div&gt;&lt;/div&gt;&lt;/div&gt; through 12 to determine whether extinguishment accounting was appropriate. The modification had a cash flow effect on a present value basis of less than 10%. However, the reduction in the conversion price resulted in a change in the fair value of the embedded conversion option that was more than 10% of the carrying value of the Note immediately prior to the modification. Because the amendment resulted in a substantial modification, extinguishment accounting was required, and we recorded a loss on the extinguishment of debt of $290,024. The extinguishment accounting resulted in a fair value reacquisition price of this debt of $1,340,024. The premium of $290,024 was being amortized over the remaining life of the debt. The warrant modification was treated as an inducement to extend the debt therefore the fair value of the warrants of $868,878 was a period expense and charged to interest expense with an offset to equity. &lt;/div&gt;&lt;div style="text-indent: 9%; font-family: times new roman; font-size: 10pt; margin-top: 18pt; margin-bottom: 0pt;"&gt;&lt;div style="font-family: &amp;quot;times new roman&amp;quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;"&gt;&lt;div style="font-weight:bold;display:inline;"&gt;&lt;div style="font-style:italic;display:inline;;font-style:italic;display:inline;"&gt;Term Extension (August 14, 2020) &lt;/div&gt;&lt;/div&gt;&lt;/div&gt;&lt;/div&gt;&lt;div style="text-indent: 9%; font-family: times new roman; font-size: 10pt; margin-top: 6pt; margin-bottom: 0pt;"&gt;&lt;div style="font-family: &amp;quot;times new roman&amp;quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;"&gt;On August&amp;#160;14, 2020, we entered into a Third Amendment to Note and Warrant Purchase Agreement and Note and Warrant Modification Agreement (the &amp;#8220;Third Amendment&amp;#8221;) with the Lenders. Certain terms and provisions of the Notes were modified, and we issued a new warrant to purchase common stock to each of the Lenders as consideration for them entering into the Third Amendment. The warrants have an exercise price of $4.67 and are exercisable any time until August&amp;#160;14, 2023.

As amended by the Third Amendment, the Notes are convertible into an aggregate of 263,993 shares of our common stock, and the new Warrants are exercisable to purchase an aggregate of 131,996 shares of our common stock for $4.67 per share. &lt;/div&gt;&lt;/div&gt;&lt;div style="text-indent: 9%; font-family: times new roman; font-size: 10pt; margin-top: 12pt; margin-bottom: 0pt;"&gt;The modification of the Notes and the issuance of the warrants, were evaluated under ASC &lt;div style="white-space: nowrap; letter-spacing: 0px; top: 0px;;display:inline;"&gt;&lt;div style="white-space: nowrap; letter-spacing: 0px; top: 0px;;display:inline;"&gt;470-50-40,&lt;/div&gt;&lt;/div&gt; &amp;#8220;Debt Modification and Extinguishments.&amp;#8221; By applying the guidance, the Notes were determined to be substantially different and the transaction qualified for extinguishment accounting. As a result, we recorded a loss on extinguishment of approximately $777,500, which included the fair value of the warrants given as consideration for the modification. The premium of $358,497 is being amortized over the remaining life of the debt.

Upon exhaustion of the Tranche&amp;#160;A Committed Amount, the Claimholder will have the option to request Tranche&amp;#160;B of the Phase&amp;#160;II Investment Amount, consisting of funding of up to $1.5&amp;#160;million (&amp;#8220;Tranche&amp;#160;B Committed Amount&amp;#8221;). The Claimholder must exercise its option to receive the Tranche&amp;#160;A Committed Amount in writing, no less than thirty days before submitting a Funding Request to the Funder under Tranche&amp;#160;A. The Claimholder must exercise its option to receive the Tranche&amp;#160;B Committed Amount in writing within forty-five days after the exhaustion of the Tranche&amp;#160;A Committed Amount. Pursuant to the Agreement, the Claimholder agreed that, upon exercising the Claimholder&amp;#8217;s option to receive funds under Phase&amp;#160;I, Tranche&amp;#160;A of Phase&amp;#160;II, or Tranche&amp;#160;B of Phase&amp;#160;II, the Funder will be the sole source of third-party funding for the specified fees and expenses of the Subject Claim under each respective phase and tranche covered by the option exercised, and the Claimholder will obtain funding for such fees and expenses only as set forth in the Agreement. The Funder was due closing fee of $80,000 for the Phase&amp;#160;I Investment Amount, and $80,000 for the Phase&amp;#160;II Investment Amount to pay third parties in connection with due diligence and other administrative and transaction costs incurred by the Funder prior to and in furtherance of execution of the Agreement. &lt;/div&gt;&lt;/div&gt;&lt;div style="text-indent: 9%; font-family: times new roman; font-size: 10pt; margin-top: 12pt; margin-bottom: 0pt;"&gt;&lt;div style="font-family: &amp;quot;times new roman&amp;quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;"&gt;Upon the Funder making Claims Payments to the Claimholder or its designees in an aggregate amount equal to the Maximum Investment Amount, the Funder has the option to continue funding the specified fees and expenses in relation to the Subject Claim on the same terms and conditions provided in the Agreement. The Funder must exercise its option to continue funding in writing, within thirty days after the Funder has made Claims Payments in an aggregate amount equal to the Maximum Investment Amount. If the Funder exercises its option to continue funding, the parties agreed to attempt in good faith to amend the Agreement to provide the Funder with the right to provide at the Funder&amp;#8217;s discretion funding in excess of the Maximum Investment Amount, in an amount up to the greatest amount that may then be reasonably expected to be committed for investment in Subject Claim. If the Funder declines to exercise its option, the Claimholder may negotiate and enter into agreements with one or more third parties to provide funding, which shall be subordinate to the Funder&amp;#8217;s rights under the Agreement. &lt;/div&gt;&lt;/div&gt;&lt;div style="text-indent: 9%; font-family: times new roman; font-size: 10pt; margin-top: 12pt; margin-bottom: 0pt;"&gt;&lt;div style="font-family: &amp;quot;times new roman&amp;quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;"&gt;The Agreement provides that the Claimholder may at any time without the consent of the Funder either settle or refuse to settle the Subject Claim for any amount; provided, however, that if the Claimholder settles the Subject Claim without the Funder&amp;#8217;s consent, which consent shall not be unreasonably withheld, conditioned, or delayed, the value of the Recovery Percentage (as defined below) will be deemed to be the greater of (a)&amp;#160;the Recovery Percentage (under Phase&amp;#160;I or Phase&amp;#160;II, as applicable), or (b)&amp;#160;the total amount of all Claims Payments made in connection with such Subject Claim multiplied by three (3). &lt;/div&gt;&lt;div style="font-size: 1px; letter-spacing: 0px; top: 0px;;display:inline;"&gt;&amp;#160;&lt;/div&gt;&lt;/div&gt;&lt;div style="text-indent: 9%; font-family: &amp;quot;times new roman&amp;quot;; font-size: 10pt; margin-top: 12pt; margin-bottom: 0pt; line-height: 12pt;"&gt;If the Claimholder ceases the Subject Claim for any reason other than (a)&amp;#160;a full and final arbitral award against the Claimholder or (b)&amp;#160;a full and final monetary settlement of the claims, including in particular, for a grant of an environmental permit to the Claimholder allowing it to proceed with the Project (with or without a monetary component), all Claims Payments under Phase&amp;#160;I and, if Claimholder has exercised the corresponding option, the Tranche&amp;#160;A Committed Amount and Tranche&amp;#160;B Committed Amount, shall immediately convert to a senior secured liability of the Claimholder. This sum shall incur an annualized internal rate of return (IRR) of 50.0% retroactive to the date each Funding Request was paid by the Funder (under Phase&amp;#160;I), or, to the conversion date for the Tranche&amp;#160;A Committed Amount and Tranche&amp;#160;B Committed Amount of Phase&amp;#160;II if the Claimholder has exercised the respective option (collectively, the &amp;#8220;Conversion Amount&amp;#8221;). Such Conversion Amount and any and all accrued IRR shall be &lt;div style="white-space: nowrap; letter-spacing: 0px; top: 0px;;display:inline;"&gt;payable&amp;#160;in-full&amp;#160;by&lt;/div&gt; the Claimholder within 24 months of the date of such conversion, after which time any outstanding Conversion Amounts, shall accrue an (IRR) of 100.0%, retroactive to the conversion date (the &amp;#8220;Penalty Interest Amount&amp;#8221;). The Claimholder will execute such documents and take other actions as necessary to grant the Funder a senior security interest on and over all sums due and owing by the Claimholder in order to secure its obligation to pay the Conversion Amount to the Funder. If the Claimholder ceases the Subject Claim due to the grant of an environmental permit (with or without a monetary component), all Claims Payments under Phase 1 and, if the Claimholder has exercised the corresponding option, the Tranche A Committed Amount and Tranche B Committed Amount shall immediately convert to a senior secured liability of the Claimholder and shall incur an annualized an IRR of 50.0% on the Conversion Amount, from the conversion date. Management has estimated it is more likely than not the Subject Claim will result in the issuance of the environmental permit requiring us to record interest under Generally Accepted Accounting Principles. Reliance should not be placed on this estimate in determining the likely outcome of the Subject Claim. &lt;/div&gt;&lt;div style="text-indent: 9%; font-family: times new roman; font-size: 10pt; margin-top: 12pt; margin-bottom: 0pt;"&gt;If, at any time after exercising its option to receive funds under either Tranche&amp;#160;A or Tranche&amp;#160;B of Phase&amp;#160;II, the Claimholder wishes to fund the Subject Claim with its own capital (&amp;#8220;Self-Funding&amp;#8221;) (which excludes any Claims Payments made, either directly or indirectly, by any other third party), the Claimholder shall immediately pay to the Funder the Conversion Amount, provided that this requirement shall not apply if, after the Funder has made Claims Payments in an aggregate amount equal to the Maximum Investment Amount, the Funder does not exercise its option to provide &lt;div style="white-space: nowrap; letter-spacing: 0px; top: 0px;;display:inline;"&gt;Follow-On&amp;#160;Funding.&lt;/div&gt; &lt;/div&gt;&lt;div style="text-indent: 9%; font-family: times new roman; font-size: 10pt; margin-top: 12pt; margin-bottom: 0pt;"&gt;In the event of any receipt of proceeds resulting from the Subject Claim&amp;#160;(&amp;#8220;Proceeds&amp;#8221;), the Funder shall be entitled to any additional sums above the Conversion Amount to which the Funder is entitled as described below. Should the Claimholder cease the Subject Claim as described above after Self-Funding the Claim, accrued IRR and Penalty Interest shall be calculated and paid to the Funder as set forth above. The Funder&amp;#8217;s rights to the Recovery Percentage as defined below shall survive any decision by Claimholder to utilize Self-Funding. The parties acknowledge this Agreement constitutes a sale of the right to a portion of the Proceeds (if any) arising from the Subject Claim as set forth in this Agreement. The Claimholder has relinquished its right to the portion of the proceeds, if any, that the Funder would have the right to as described below.

If (a)&amp;#160;Proceeds are paid to or received by the Claimholder or its representatives; (b)&amp;#160;such Proceeds are promptly applied and/or distributed by the Claimholder or on behalf of the Claimholder in accordance with the terms of the Agreement; and (c)&amp;#160;the amount received by the Funder as a result thereof is not sufficient to pay all of the Recovery Percentage and all of the amounts due to the Funder under the Agreement, then (provided that all of the Proceeds which the Funder will ever be entitled to have been paid to or received by the Funder), the Funder shall have no right of recourse or action against the Claimholder or its Representatives, or any of their property, assets, or undertakings, except as otherwise specifically contemplated by the Agreement. Pursuant to the Agreement, the Claimholder acknowledged the Funder&amp;#8217;s priority right, title, and interest in any Proceeds, including against any available collateral to secure its obligations under the Agreement, which security interest shall be first in priority as against all other security interests in the Proceeds. The Claimholder also acknowledged and agreed to execute and authorize the filing of a financing statement or similar and to take such other actions in such jurisdictions as the Funder, in its sole discretion, deems necessary and appropriate to perfect such security interest. The Agreement also includes representations and warranties, covenants, conditions, termination and indemnification provisions, and other provisions customary for comparable arrangements. &lt;/div&gt;&lt;/div&gt;&lt;div style="text-indent: 9%; font-family: times new roman; font-size: 10pt; margin-top: 18pt; margin-bottom: 0pt;"&gt;&lt;div style="font-family: &amp;quot;times new roman&amp;quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;"&gt;&lt;div style="font-weight:bold;display:inline;"&gt;&lt;div style="font-style:italic;display:inline;;font-style:italic;display:inline;"&gt;Amendment and Restatement (January 31, 2020) &lt;/div&gt;&lt;/div&gt;&lt;/div&gt;&lt;/div&gt;&lt;div style="text-indent: 9%; font-family: times new roman; font-size: 10pt; margin-top: 6pt; margin-bottom: 0pt;"&gt;&lt;div style="font-family: &amp;quot;times new roman&amp;quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;"&gt;On January&amp;#160;31, 2020, the Claimholder and the Funder entered into an Amended and Restated International Claims Enforcement Agreement (the &amp;#8220;Restated Agreement&amp;#8221;).

Upon each funding, the proceeds were allocated between debt and equity for the warrants based on the relative fair value of the two instruments. As a result, there was a debt discount of $1,063,811 which is being amortized over the expected remaining term of the agreement using the effective interest method which is charged to interest expense. &lt;/div&gt;&lt;br/&gt;&lt;/div&gt;&lt;div style="text-indent: 9%; font-family: &amp;quot;times new roman&amp;quot;; font-size: 10pt; margin-top: 12pt; margin-bottom: 0pt; line-height: 12pt;"&gt;&lt;div style="font-family: &amp;quot;times new roman&amp;quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;"&gt;Although the warrants only become exercisable upon the occurrence of future events, they are considered issued for accounting purposes and were valued using a binomial lattice model. The expected volatility assumption was based on the historical volatility of our common stock. The expected life assumption was primarily based on management&amp;#8217;s expectations of when the Warrants will become exercisable and the risk-free interest rate for the expected term of the warrant is based on the U.S. Treasury yield curve in effect at the time of measurement. &lt;/div&gt;&lt;/div&gt;&lt;div style="text-indent: 9%; font-family: times new roman; font-size: 10pt; margin-top: 18pt; margin-bottom: 0pt;"&gt;&lt;div style="font-family: &amp;quot;times new roman&amp;quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;"&gt;&lt;div style="font-weight:bold;display:inline;"&gt;&lt;div style="font-style:italic;display:inline;;font-style:italic;display:inline;"&gt;Second Amendment and Restatement (December 12, 2020) &lt;/div&gt;&lt;/div&gt;&lt;/div&gt;&lt;/div&gt;&lt;div style="text-indent: 9%; font-family: times new roman; font-size: 10pt; margin-top: 6pt; margin-bottom: 0pt;"&gt;&lt;div style="font-family: &amp;quot;times new roman&amp;quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;"&gt;On December&amp;#160;12, 2020, the Claimholder and the Funder entered into a Second Amended and Restated International Claims Enforcement Agreement (the &amp;#8220;Second Restated Agreement&amp;#8221;) relating to the Subject Claim. Under the terms of the Second Restated Agreement, the Funder has made and agreed to make Claims Payments in an aggregate amount not to exceed $20,000,000 (the &amp;#8220;Maximum Investment Amount&amp;#8221;). The Second Restated Agreement requires the Funder to make Claims Payments in an aggregate amount no greater than $10,000,000 for the purposes of pursuing the Subject Claim to a final award (&amp;#8220;Phase&amp;#160;III Investment Amount&amp;#8221;). We also incurred $200,000 in related fees which were treated as an additional advance. This Second Restated Agreement includes the same representations and warranties, covenants, conditions, termination and indemnification provisions, and other provisions as in the original agreement. &lt;/div&gt;&lt;/div&gt;&lt;div style="text-indent: 9%; font-family: times new roman; font-size: 10pt; margin-top: 12pt; margin-bottom: 0pt;"&gt;&lt;div style="font-family: &amp;quot;times new roman&amp;quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;"&gt;For the twelve months ended December&amp;#160;31, 2020 and 2019, interest expense in the amount of $3,668,242 and $369,505, respectively, was recorded. For the twelve months ended December&amp;#160;31, 2020, we recorded $172,849 of interest expense from the amortization of the debt discount and $52,214 interest from the fee amortization. The December&amp;#160;31, 2020 carrying value of the note is $10,968,729 and is net of unamortized debt fees of $347,786 as well as the net unamortized debt discount of $890,962 associated with the fair value of the warrants. The total face value of this obligation at December&amp;#160;31, 2020 and 2019 was $12,207,477 and $2,957,097, respectively. &lt;/div&gt;&lt;/div&gt;&lt;div style="font-family: times new roman; font-size: 10pt; margin-top: 18pt; margin-bottom: 0pt;"&gt;&lt;div style="font-family: &amp;quot;times new roman&amp;quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;"&gt;&lt;div style="font-weight:bold;display:inline;"&gt;Note 10 &amp;#8211; 37North &lt;/div&gt;&lt;/div&gt;&lt;/div&gt;&lt;div style="text-indent: 9%; font-family: times new roman; font-size: 10pt; margin-top: 6pt; margin-bottom: 0pt;"&gt;&lt;div style="font-family: &amp;quot;times new roman&amp;quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;"&gt;On December&amp;#160;6, 2019, we entered into a Note Purchase Agreement (the &amp;#8220;Purchase Agreement&amp;#8221;) with 37North Capital SPV 11, LLC (the &amp;#8220;Investor&amp;#8221;) pursuant to which the Investor agreed to lend, in one or more transactions (each, a &amp;#8220;Loan&amp;#8221;), up to an aggregate of $2.0&amp;#160;million to us, subject to the terms and conditions of the Purchase Agreement. On December&amp;#160;10, 2019, the Investor made a Loan to us in the amount of $539,000 pursuant to the Purchase Agreement. An additional Loan of $490,000 was made in the first quarter of 2020. Each Loan is evidenced by a separate convertible promissory note (each, a &amp;#8220;Note&amp;#8221;). Unless otherwise converted as described below, the entire outstanding amount of all Loans was originally due and payable on June&amp;#160;6, 2020. As described in additional detail below, the maturity date was subsequently extended to November&amp;#160;6, 2020, and on December&amp;#160;8, 2020, the Company waived the maturity date extension causing the maturity date to revert back to June&amp;#160;6, 2020 (the &amp;#8220;Maturity Date&amp;#8221;). &lt;/div&gt;&lt;/div&gt;&lt;div style="text-indent: 9%; font-family: times new roman; font-size: 10pt; margin-top: 12pt; margin-bottom: 0pt;"&gt;At any time and from time to time until the three-month anniversary of the Maturity Date, all or any portion of the outstanding amount of each Note may, at the Investor&amp;#8217;s election, be converted into shares of our common stock, par value $0.0001 per share (&amp;#8220;Conversion Shares&amp;#8221;). The number of Conversion Shares to be issued upon any conversion shall be equal to the quotient obtained by dividing the Applicable Conversion Amount (as defined below)&amp;#160;by the Applicable Conversion Rate (as defined below). As defined in the Purchase Agreement, the &amp;#8220;Applicable Conversion Amount&amp;#8221; means, on the date of determination and with respect to each Note, (a)&amp;#160;for the period beginning on the date of issuance and ending on the day immediately preceding the Maturity Date, an amount equal to 100.0% of the amount of the Loan evidenced by such Note then outstanding; (b)&amp;#160;on the Maturity Date, 136.0% of the amount of the Loan evidenced by such Note then outstanding (such amount, the &amp;#8220;Enhanced Conversion Amount&amp;#8221;); (c)&amp;#160;for the period beginning on the day immediately following the Maturity Date and for a period of three months thereafter (such three-month period, the &amp;#8220;Accrual Period&amp;#8221;), an amount equal to (i)&amp;#160;the Enhanced Conversion Amount then outstanding plus (ii)&amp;#160;an additional amount equal to 3.0% per month (prorated for any period of less than a full month) accrued on the amount described in clause (i); and (d)&amp;#160;on any date after the Accrual Period, the amount then outstanding after giving effect to the accrual described in clause (c)&amp;#160;during the Accrual Period (it being understood that no additional amount shall accrue after the expiration of the Accrual Period); and &amp;#8220;Applicable Conversion Rate&amp;#8221; means (x)&amp;#160;with respect to any conversion on or prior to the Maturity Date, $5.00, and (y)&amp;#160;with respect to any conversion after the Maturity Date, the lower of (i) $5.00 and (ii) 80.0% of &lt;div style="white-space: nowrap; letter-spacing: 0px; top: 0px;;display:inline;"&gt;the&amp;#160;ten-day&amp;#160;volume-weighted&lt;/div&gt; average price of Odyssey&amp;#8217;s common stock. Notwithstanding anything in the Purchase Agreement to the contrary, we are prohibited from issuing any Conversion Shares, to the extent such shares, after giving effect to such issuance after conversion and when added to the number of Conversion Shares previously issued upon conversion of any of the Notes sold pursuant to the Purchase Agreement, would represent in excess of 19.9% of (A)&amp;#160;the number of shares of our common stock outstanding immediately after giving effect to such issuances or (B)&amp;#160;the total voting power of our securities outstanding immediately after giving effect to such issuances that are entitled to vote on a matter being voted on by holders of our common stock. &lt;div style="font-size: 1px; letter-spacing: 0px; top: 0px;;display:inline;"&gt;&amp;#160;&lt;/div&gt;&lt;/div&gt;&lt;div style="text-indent: 9%; font-family: &amp;quot;times new roman&amp;quot;; font-size: 10pt; margin-top: 12pt; margin-bottom: 0pt; line-height: 12pt;"&gt;On May&amp;#160;6, 2020, Odyssey and the Investor agreed to amend the Purchase Agreement to additionally provide that, notwithstanding anything in the Purchase Agreement to the contrary, Odyssey is prohibited from issuing any Conversion Shares, to the extent such shares, after giving effect to such issuance after conversion and when added to the number of Conversion Shares previously issued upon conversion of any of the Notes sold pursuant to the Purchase Agreement, would represent in excess of 19.9% of the number of shares of Common Stock outstanding as of December&amp;#160;6, 2019. Due to a reference to the effective date of the amendment in the definition of the maturity date, the maturity date of the Note was inadvertently revised from June&amp;#160;6, 2020 to November&amp;#160;6, 2020. Thus, on December&amp;#160;8, 2020 the Company amended the Notes to adjust the maturity date back to the original date of June&amp;#160;6, 2020 and to extend the option to convert to December&amp;#160;31, 2020. The modifications were evaluated under FASB ASC Topic &lt;div style="white-space: nowrap; letter-spacing: 0px; top: 0px;;display:inline;"&gt;&lt;div style="white-space: nowrap; letter-spacing: 0px; top: 0px;;display:inline;"&gt;470-50-40,&lt;/div&gt;&lt;/div&gt; &amp;#8220;Debt Modification and Extinguishments&amp;#8221; but the instruments were determined not to be substantially different and extinguishment accounting did not apply. &lt;/div&gt;&lt;div style="text-indent: 9%; font-family: times new roman; font-size: 10pt; margin-top: 12pt; margin-bottom: 0pt;"&gt;&lt;div style="font-family: &amp;quot;times new roman&amp;quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;"&gt;During the year ended December&amp;#160;31, 2020, the Investor converted the entire loan balance into 329,498 shares of our common stock at conversion rates ranging from $3.71 to $5.00 per share. &lt;/div&gt;&lt;/div&gt;&lt;div style="text-indent: 9%; font-family: times new roman; font-size: 10pt; margin-top: 12pt; margin-bottom: 0pt;"&gt;&lt;div style="font-family: &amp;quot;times new roman&amp;quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;"&gt;If, at any time prior to the Maturity Date, (a)&amp;#160;we receive cash proceeds (the &amp;#8220;Shipwreck Proceeds&amp;#8221;) arising out of our salvage agreement relating to cargo recovered from a specified shipwreck, and (ii)&amp;#160;the amount of the Shipwreck Proceeds equals at least 155.0% of the then-unpaid amount of all Loans, then we must repay in full the indebtedness outstanding under all the Notes by delivery of an amount equal to 155.0% of the then-unpaid amount of all Loans. In addition, at any time prior to the Maturity Date, we may repay all (but not less than all) of the then-unpaid amount of all Loans by delivery of an amount equal to 155.0% of the then-unpaid amount of all Loans; provided, that we must provide the Investor at least ten days&amp;#8217; notice of our intention to repay the indebtedness. &lt;/div&gt;&lt;/div&gt;&lt;div style="text-indent: 9%; font-family: times new roman; font-size: 10pt; margin-top: 12pt; margin-bottom: 0pt;"&gt;&lt;div style="font-family: &amp;quot;times new roman&amp;quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;"&gt;The Purchase Agreement and the Notes issued by Odyssey on December&amp;#160;10, 2019 and January&amp;#160;29, 2020, include representations and warranties and other covenants, conditions, and other provisions customary for comparable transactions. &lt;/div&gt;&lt;/div&gt;&lt;div style="text-indent: 9%; font-family: times new roman; font-size: 10pt; margin-top: 12pt; margin-bottom: 0pt;"&gt;We evaluated the Notes in accordance with ASC Topic 815, Derivatives and Hedging, and determined that they contain certain embedded derivatives whose economic risks and characteristics were not clearly and closely related to the risks of the host contract. The material embedded derivative features consisted of the embedded conversion option and contingent redemption provisions. We elected to initially and subsequently measure the Notes in their entirety at fair value, with changes in fair value recognized in earnings. FASB &lt;div style="white-space: nowrap; letter-spacing: 0px; top: 0px;;display:inline;"&gt;&lt;div style="white-space: nowrap; letter-spacing: 0px; top: 0px;;display:inline;"&gt;ASC&amp;#160;825-10-25&amp;#160;allows&lt;/div&gt;&lt;/div&gt; us to elect the fair value option for recording financial instruments when they are initially recognized or if there is an event that &lt;div style="white-space: nowrap; letter-spacing: 0px; top: 0px;;display:inline;"&gt;requires&amp;#160;re-measurement&amp;#160;of&lt;/div&gt; the instruments at fair value, such as a significant modification of the debt. &lt;/div&gt;&lt;div style="text-indent: 9%; font-family: times new roman; font-size: 10pt; margin-top: 12pt; margin-bottom: 0pt;"&gt;&lt;div style="font-family: &amp;quot;times new roman&amp;quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;"&gt;Because the Notes are carried in their entirety at fair value, the value of the compound embedded conversion feature is embodied in that fair value. The Company estimates the fair value of the hybrid instrument based on a probability weighted analysis which considers the present value of the cash flows using a credit risk adjusted rate enhanced by the redemption feature and the value of the conversion option valued using a Monte Carlo model. This method was considered by management to be the most appropriate method of encompassing the credit risk and exercise behavior that a market participant would consider when valuing the hybrid financial instrument. &lt;/div&gt;&lt;/div&gt;&lt;div style="text-indent: 9%; font-family: times new roman; font-size: 10pt; margin-top: 12pt; margin-bottom: 0pt;"&gt;Inputs used to value the hybrid instrument during the year ended December&amp;#160;31, 2020 included, (i)&amp;#160;present value of future cash flows using a credit risk adjusted rate ranging from &lt;div style="white-space: nowrap; letter-spacing: 0px; top: 0px;;display:inline;"&gt;18%-24%&lt;/div&gt; due solely to changes in benchmark interest rates, (ii)&amp;#160;remaining term to maturity, (iii)&amp;#160;volatility ranging from &lt;div style="white-space: nowrap; letter-spacing: 0px; top: 0px;;display:inline;"&gt;35%-87%,&lt;/div&gt; (iv) closing stock price on the valuation date, and (v)&amp;#160;the conversion price based on the lesser of $5.00 or 80% of the &lt;div style="white-space: nowrap; letter-spacing: 0px; top: 0px;;display:inline;"&gt;10-day&lt;/div&gt; VWAP. Material changes due to instrument-specific credit risk are recorded in Other Comprehensive Income with all other changes in value being recorded in net income.&lt;/div&gt;&lt;div style="text-indent: 9%; font-family: times new roman; font-size: 10pt; margin-top: 12pt; margin-bottom: 0pt;"&gt;&lt;div style="font-family: &amp;quot;times new roman&amp;quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;"&gt;The fair value of the hybrid instrument was $861,484 as of December&amp;#160;31, 2019. During the year ended December&amp;#160;31, 2020, we received additional proceeds of $490,000, recorded a change in the fair value of the hybrid instrument of $732,958 and fully converted the Notes into 329,498 shares of our Common Stock. &lt;/div&gt;&lt;/div&gt;&lt;div style="font-family: times new roman; font-size: 10pt; margin-top: 18pt; margin-bottom: 0pt;"&gt;&lt;div style="font-family: &amp;quot;times new roman&amp;quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;"&gt;&lt;div style="font-weight:bold;display:inline;"&gt;Note 11 &amp;#8211; Payroll protection program &lt;/div&gt;&lt;/div&gt;&lt;/div&gt;&lt;div style="text-indent: 9%; font-family: times new roman; font-size: 10pt; margin-top: 6pt; margin-bottom: 0pt;"&gt;&lt;div style="font-family: &amp;quot;times new roman&amp;quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;"&gt;We applied to Fifth Third Bancorp (&amp;#8220;Fifth Third&amp;#8221;) under the Small Business Administration (the &amp;#8220;SBA&amp;#8221;) Paycheck Protection Program of the Coronavirus Aid, Relief and Economic Security Act of 2020 (the &amp;#8220;CARES Act&amp;#8221;) for a loan of $370,400 (the &amp;#8220;Loan&amp;#8221;), and the Loan was made on April&amp;#160;16, 2020. The proceeds of the Loan were used to cover payroll costs, rent and utilities in accordance with the relevant terms and conditions of the CARES Act. &lt;/div&gt;&lt;div style="font-size: 1px; letter-spacing: 0px; top: 0px;;display:inline;"&gt;&amp;#160;&lt;/div&gt;&lt;/div&gt;&lt;div style="text-indent: 9%; font-family: &amp;quot;times new roman&amp;quot;; font-size: 10pt; margin-top: 12pt; margin-bottom: 0pt; line-height: 12pt;"&gt;The Loan, which is evidenced by promissory note issued by us (the &amp;#8220;Promissory Note&amp;#8221;), has &lt;div style="white-space: nowrap; letter-spacing: 0px; top: 0px;;display:inline;"&gt;a&amp;#160;two-year&amp;#160;term,&lt;/div&gt; matures on April&amp;#160;16, 2022, and bears interest at a rate of 0.98% per annum. Monthly principal and interest payments, less the amount of any potential forgiveness (discussed below), will commence seven months from the month this Note is dated. We did not provide any collateral or guarantees for the Loan, nor did we pay any facility charge to obtain the Loan. The Promissory Note provides for customary events of default, including, among others, those relating to failure to make payment, bankruptcy, breaches of representations and material adverse effects. Odyssey may prepay the principal of the Loan at any time without incurring any prepayment charges. For the twelve months ended December&amp;#160;31, 2020 and 2019, we recorded interest expense in the amount of $936 and $0, respectively. &lt;/div&gt;&lt;div style="text-indent: 9%; font-family: times new roman; font-size: 10pt; margin-top: 12pt; margin-bottom: 0pt;"&gt;The Loan may be forgiven partially or fully if the Loan proceeds are used for covered payroll costs, rent and utilities, provided that such amounts are incurred during the eight-week period that commenced on April&amp;#160;16, 2020, and at least 75% of any forgiven amount has been used for covered payroll costs. During June 2020, the 75% requirement was reduced to 60% and the eight-week period was amended to a &lt;div style="white-space: nowrap; letter-spacing: 0px; top: 0px;;display:inline;"&gt;24-week&lt;/div&gt; period. Any forgiveness of the Loan will be subject to approval by the SBA and Fifth Third and will require us to apply for such treatment in the future. &lt;/div&gt;&lt;div style="font-family: times new roman; font-size: 10pt; margin-top: 18pt; margin-bottom: 0pt;"&gt;&lt;div style="font-family: &amp;quot;times new roman&amp;quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;"&gt;&lt;div style="font-weight:bold;display:inline;"&gt;Note 12 &amp;#8211; Emergency Injury Disaster Loan &lt;/div&gt;&lt;/div&gt;&lt;/div&gt;&lt;div style="text-indent: 9%; font-family: times new roman; font-size: 10pt; margin-top: 6pt; margin-bottom: 0pt;"&gt;&lt;div style="font-family: &amp;quot;times new roman&amp;quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;"&gt;On June&amp;#160;26, 2020, we executed the standard loan documents required for securing an Economic Injury Disaster Loan (the &amp;#8220;EIDL Loan&amp;#8221;) from the United States Small Business Administration (the &amp;#8220;SBA&amp;#8221;). The principal amount of the EIDL Loan is $149,900, with proceeds to be used for working capital purposes. Interest on the&amp;#160;EIDL Loan accrues at the rate of 3.75% per annum and installment payments, including principal and interest of $731, are due monthly beginning twelve months from the date of the&amp;#160;EIDL Loan. The balance of principal and interest is payable thirty years from the date of the promissory note. In connection with the&amp;#160;EIDL Loan, the Company executed the&amp;#160;EIDL Loan documents, which include the SBA Secured Disaster Loan Note, dated May&amp;#160;16, 2020, the Loan Authorization and Agreement, dated May&amp;#160;16, 2020, and the Security Agreement, dated May&amp;#160;16, 2020, each between the SBA and the Company. &lt;/div&gt;&lt;/div&gt;&lt;div style="font-family: times new roman; font-size: 10pt; margin-top: 18pt; margin-bottom: 0pt;"&gt;&lt;div style="font-family: &amp;quot;times new roman&amp;quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;"&gt;&lt;div style="font-weight:bold;display:inline;"&gt;Long-Term Obligation Maturities: &lt;/div&gt;&lt;/div&gt;&lt;/div&gt;&lt;div style="text-indent: 9%; font-family: times new roman; font-size: 10pt; margin-top: 6pt; margin-bottom: 0pt;"&gt;&lt;div style="font-family: &amp;quot;times new roman&amp;quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;"&gt;We have two obligations that span greater than twelve months.

Monaco also agreed to treat $99,366 of back rent owed by us to Monaco as part of this loan resulting in an aggregate principal amount of $1,099,367 at December 31, 2020 and 2019. The indebtedness bears interest at 10.0% percent per year. During January 2020 this loan agreement was amended by increasing the interest rate to 18%. All principal and any unpaid interest is to be payable on the first anniversary of this agreement, April 20, 2019. This debt is secured by cash proceeds, if any, from our future shipwreck projects we have contracted with Magellan. As additional consideration, their share purchase option expiration date, as discussed in Note 1 &amp;#8211; Monaco 2014 and Note 2 &amp;#8211; Monaco 2016 above, has been extended from 30 days to seven months after the note becomes paid in full. For the twelve months ended December 31, 2020 and 2019, interest in the amount of $138,333 and $123,466, respectively, was recorded.</us-gaap:DebtInstrumentDescription>

If Odyssey pays a dividend or makes a distribution on its common stock in shares of common stock, subdivides its outstanding common stock into a greater number of shares, or combines its outstanding common stock into a smaller number of shares, or if there is a reorganization, or a merger or consolidation of Odyssey with or into any other entity which results in a conversion, exchange, or cancellation of the common stock, or a sale of all or substantially all of Odyssey&amp;#8217;s assets, then the conversion rights described above will be adjusted appropriately so that each holder of Series AA Preferred will receive the securities or other consideration the holder would have received if the holder&amp;#8217;s Series AA Preferred had been converted before the happening of the event. The conversion price in effect from time to time is also subject to downward adjustment if we issue or sell shares of common stock for a purchase price less than the conversion price or if we issue or sell shares convertible into or exercisable for shares of common stock with a conversion price or exercise price less than the conversion price for the Series AA Preferred.&lt;/div&gt;&lt;/div&gt;&lt;div style="color: rgb(0, 0, 0); font-family: 'times new roman'; font-style: normal; font-variant-ligatures: normal; font-variant-caps: normal; font-weight: 400; letter-spacing: normal; orphans: 2; text-align: start; text-indent: 0px; text-transform: none; white-space: normal; widows: 2; word-spacing: 0px; -webkit-text-stroke-width: 0px; text-decoration-thickness: initial; text-decoration-style: initial; text-decoration-color: initial; margin-top: 18pt; margin-bottom: 0pt; font-size: 10pt;"&gt;&lt;div style="font-family: &amp;quot;times new roman&amp;quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;"&gt;&lt;div style="font-weight:bold;display:inline;"&gt;&lt;div style="font-style:italic;display:inline;;font-style:italic;display:inline;"&gt;Accounting considerations&lt;/div&gt;&lt;/div&gt;&lt;/div&gt;&lt;/div&gt;&lt;div style="color: rgb(0, 0, 0); font-family: 'times new roman'; font-style: normal; font-variant-ligatures: normal; font-variant-caps: normal; font-weight: 400; letter-spacing: normal; orphans: 2; text-align: start; text-transform: none; white-space: normal; widows: 2; word-spacing: 0px; -webkit-text-stroke-width: 0px; text-decoration-thickness: initial; text-decoration-style: initial; text-decoration-color: initial; margin-top: 6pt; margin-bottom: 0pt; text-indent: 4%; font-size: 10pt;"&gt;&lt;div style="font-family: &amp;quot;times new roman&amp;quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;"&gt;As stated above the issuance of the Series AA Convertible Preferred Stock is based on certain contingencies. No accounting treatment determination is required until these contingencies are met and the Series AA Convertible Preferred Stock has been issued. However, we have analyzed the instrument to determine the proper accounting treatment that will be necessary once the instruments have been issued.&lt;/div&gt;&lt;/div&gt;&lt;div style="color: rgb(0, 0, 0); font-family: 'times new roman'; font-style: normal; font-variant-ligatures: normal; font-variant-caps: normal; font-weight: 400; letter-spacing: normal; orphans: 2; text-align: start; text-transform: none; white-space: normal; widows: 2; word-spacing: 0px; -webkit-text-stroke-width: 0px; text-decoration-thickness: initial; text-decoration-style: initial; text-decoration-color: initial; margin-top: 12pt; margin-bottom: 0pt; text-indent: 4%; font-size: 10pt;"&gt;&lt;div style="font-family: &amp;quot;times new roman&amp;quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;"&gt;ASC 480 generally requires liability classification for financial instruments that are certain to be redeemed, represent obligations to purchase shares of stock or represent obligations to issue a variable number of common shares. We concluded that the Series AA Preferred was not within the scope of ASC 480 because none of the three conditions for liability classification was present.&lt;/div&gt;&lt;/div&gt;&lt;div style="color: rgb(0, 0, 0); font-family: 'times new roman'; font-style: normal; font-variant-ligatures: normal; font-variant-caps: normal; font-weight: 400; letter-spacing: normal; orphans: 2; text-align: start; text-transform: none; white-space: normal; widows: 2; word-spacing: 0px; -webkit-text-stroke-width: 0px; text-decoration-thickness: initial; text-decoration-style: initial; text-decoration-color: initial; margin-top: 12pt; margin-bottom: 0pt; text-indent: 4%; font-size: 10pt;"&gt;&lt;div style="font-family: &amp;quot;times new roman&amp;quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;"&gt;ASC 815 generally requires the analysis of embedded terms and features that have characteristics of derivatives to be evaluated for bifurcation and separate accounting in instances where their economic risks and characteristics are not clearly and closely related to the risks of the host contract. However, in order to perform this analysis, we were first required to evaluate the economic risks and characteristics of the Series AA Convertible Preferred Stock in its entirety as being either akin to equity or akin to debt. Our evaluation concluded that the Series AA Convertible Preferred Stock was more akin to an equity-like contract largely due to the fact that most of its features were participatory in nature. As a result, we concluded that the embedded conversion feature is clearly and closely related to the host equity contract and will not require bifurcation and liability classification.&lt;/div&gt;&lt;/div&gt;&lt;div style="color: rgb(0, 0, 0); font-family: 'times new roman'; font-style: normal; font-variant-ligatures: normal; font-variant-caps: normal; font-weight: 400; letter-spacing: normal; orphans: 2; text-align: start; text-transform: none; white-space: normal; widows: 2; word-spacing: 0px; -webkit-text-stroke-width: 0px; text-decoration-thickness: initial; text-decoration-style: initial; text-decoration-color: initial; margin-top: 12pt; margin-bottom: 0pt; text-indent: 4%; font-size: 10pt;"&gt;The option to purchase the Series&lt;div style="letter-spacing: 0px; top: 0px;;display:inline;"&gt;&amp;#160;&lt;/div&gt;&lt;div style="white-space: nowrap; letter-spacing: 0px; top: 0px;;display:inline;"&gt;AA-2&lt;/div&gt;&lt;div style="letter-spacing: 0px; top: 0px;;display:inline;"&gt;&amp;#160;&lt;/div&gt;Convertible Preferred Stock was analyzed as a freestanding financial instrument and has terms and features of derivative financial instruments. However, in analyzing this instrument under applicable guidance it was determined that it is both (i)&amp;#160;indexed to the Company&amp;#8217;s stock and (ii)&amp;#160;meet the conditions for equity classification.&lt;/div&gt;&lt;div style="color: rgb(0, 0, 0); font-family: 'times new roman'; font-style: normal; font-variant-ligatures: normal; font-variant-caps: normal; font-weight: 400; letter-spacing: normal; orphans: 2; text-align: start; text-indent: 0px; text-transform: none; white-space: normal; widows: 2; word-spacing: 0px; -webkit-text-stroke-width: 0px; text-decoration-thickness: initial; text-decoration-style: initial; text-decoration-color: initial; margin-top: 18pt; margin-bottom: 0pt; font-size: 10pt;"&gt;&lt;div style="font-family: &amp;quot;times new roman&amp;quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;"&gt;&lt;div style="font-weight:bold;display:inline;"&gt;Stock-Based Compensation&lt;/div&gt;&lt;/div&gt;&lt;/div&gt;&lt;div style="color: rgb(0, 0, 0); font-family: 'times new roman'; font-style: normal; font-variant-ligatures: normal; font-variant-caps: normal; font-weight: 400; letter-spacing: normal; orphans: 2; text-align: start; text-transform: none; white-space: normal; widows: 2; word-spacing: 0px; -webkit-text-stroke-width: 0px; text-decoration-thickness: initial; text-decoration-style: initial; text-decoration-color: initial; margin-top: 6pt; margin-bottom: 0pt; text-indent: 9%; font-size: 10pt;"&gt;&lt;div style="font-family: &amp;quot;times new roman&amp;quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;"&gt;We have three stock incentive plans. The first is the 2005 Stock Incentive Plan that expired in August 2015. After the expiration of this plan, equity instruments cannot be granted but this plan will continue in effect until all outstanding awards have been exercised in full or are no longer exercisable and all equity instruments have vested or been forfeited.&lt;/div&gt;&lt;/div&gt;&lt;div style="color: rgb(0, 0, 0); font-family: 'times new roman'; font-style: normal; font-variant-ligatures: normal; font-variant-caps: normal; font-weight: 400; letter-spacing: normal; orphans: 2; text-align: start; text-transform: none; white-space: normal; widows: 2; word-spacing: 0px; -webkit-text-stroke-width: 0px; text-decoration-thickness: initial; text-decoration-style: initial; text-decoration-color: initial; margin-top: 12pt; margin-bottom: 0pt; text-indent: 9%; font-size: 10pt;"&gt;On June&amp;#160;9, 2015, our stockholders approved our 2015 Stock Incentive Plan (the &amp;#8220;Plan&amp;#8221;) that was adopted by our Board of Directors (the &amp;#8220;Board&amp;#8221;) on January&amp;#160;2, 2015, which is the effective date. The plan expires on the tenth anniversary of the effective date. The Plan provides for the grant of incentive stock options,&lt;div style="letter-spacing: 0px; top: 0px;;display:inline;"&gt;&amp;#160;&lt;/div&gt;&lt;div style="white-space: nowrap; letter-spacing: 0px; top: 0px;;display:inline;"&gt;non-qualified&lt;/div&gt;&lt;div style="letter-spacing: 0px; top: 0px;;display:inline;"&gt;&amp;#160;&lt;/div&gt;stock options, restricted stock awards, restricted stock units and stock appreciation rights. This plan was initially capitalized with 450,000 shares that may be granted. The Plan is intended to comply with Section&amp;#160;162(m) of the Internal Revenue Code, which stipulates that the maximum aggregate number of Shares with respect to one or more Awards that may be granted to any one person during any calendar year shall be 83,333, and the maximum aggregate amount of cash that may be paid in cash to any person during any calendar year with respect to one or more Awards payable in cash shall be $2,000,000. The original maximum number of shares that were to be used for Incentive Stock Options (&amp;#8220;ISO&amp;#8221;) under the Plan was 450,000. During our June 2016 stockholders meeting, the stockholders approved the addition of 200,000 incremental shares to the Plan. With respect to each grant of an ISO to a participant who is not a ten percent stockholder, the exercise price shall not be less than the fair market value of a share on the date the ISO is granted. With respect to each grant of an ISO to a participant who is a ten percent stockholder, the exercise price shall not be less than one hundred ten percent (110%) of the fair market value of a share on the date the ISO is granted. If an award is a&lt;div style="letter-spacing: 0px; top: 0px;;display:inline;"&gt;&amp;#160;&lt;/div&gt;&lt;div style="white-space: nowrap; letter-spacing: 0px; top: 0px;;display:inline;"&gt;non-qualified&lt;/div&gt;&lt;div style="letter-spacing: 0px; top: 0px;;display:inline;"&gt;&amp;#160;&lt;/div&gt;stock option (&amp;#8220;NQSO&amp;#8221;), the exercise price for each share shall be no less than (1)&amp;#160;the minimum price required by applicable state law, or (2)&amp;#160;the fair market value of a share on the date the NQSO is granted, whichever price is greatest. Any award intended to meet the performance based exception must be granted with an exercise price not less than the fair market value of a share determined as of the date of such grant.&lt;/div&gt;&lt;div style="color: rgb(0, 0, 0); font-family: 'times new roman'; font-style: normal; font-variant-ligatures: normal; font-variant-caps: normal; font-weight: 400; letter-spacing: normal; orphans: 2; text-align: start; text-transform: none; white-space: normal; widows: 2; word-spacing: 0px; -webkit-text-stroke-width: 0px; text-decoration-thickness: initial; text-decoration-style: initial; text-decoration-color: initial; margin-top: 0pt; margin-bottom: 0pt; text-indent: 9%; font-size: 10pt;"&gt;&amp;#160;&lt;/div&gt;&lt;div style="color: rgb(0, 0, 0); font-family: 'times new roman'; font-style: normal; font-variant-ligatures: normal; font-variant-caps: normal; font-weight: 400; letter-spacing: normal; orphans: 2; text-align: start; text-transform: none; white-space: normal; widows: 2; word-spacing: 0px; -webkit-text-stroke-width: 0px; text-decoration-thickness: initial; text-decoration-style: initial; text-decoration-color: initial; margin-top: 0pt; margin-bottom: 0pt; text-indent: 9%; font-size: 10pt;"&gt;On March&amp;#160;26, 2019, our Board of Directors adopted and approved the 2019 Stock Incentive Plan (the &amp;#8220;2019 Plan&amp;#8221;), which was approved by our stockholders on June&amp;#160;3, 2019. The 2019 Plan expires on June&amp;#160;3, 2029. The 2019 Plan provides for the grant of incentive stock options,&lt;div style="letter-spacing: 0px; top: 0px;;display:inline;"&gt;&amp;#160;&lt;/div&gt;&lt;div style="white-space: nowrap; letter-spacing: 0px; top: 0px;;display:inline;"&gt;non-qualified&lt;/div&gt;&lt;div style="letter-spacing: 0px; top: 0px;;display:inline;"&gt;&amp;#160;&lt;/div&gt;stock options, restricted stock awards, restricted stock units and stock appreciation rights. The 2019 Plan is capitalized with 800,000 shares that may be granted. No awards were made from the Plan prior to the effective date. The 2019 Plan includes the following features: no &amp;#8220;evergreen&amp;#8221; share reserve, prohibits liberal share recycling, no repricing permitted without stockholder approval, no stock option reload features, no transfers of awards for value and dividends and dividends equivalent shall accrue and be paid only if and to the extent the common stock underlying the award become vested or payable.&lt;/div&gt;&lt;div style="color: rgb(0, 0, 0); font-family: 'times new roman'; font-style: normal; font-variant-ligatures: normal; font-variant-caps: normal; font-weight: 400; letter-spacing: normal; orphans: 2; text-align: start; text-transform: none; white-space: normal; widows: 2; word-spacing: 0px; -webkit-text-stroke-width: 0px; text-decoration-thickness: initial; text-decoration-style: initial; text-decoration-color: initial; margin-top: 12pt; margin-bottom: 0pt; text-indent: 9%; font-size: 10pt;"&gt;&lt;div style="font-family: &amp;quot;times new roman&amp;quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;"&gt;Share-based compensation expense recognized during the period is based on the value of the portion of share-based payment awards that is ultimately expected to vest. As share-based compensation expense recognized in the statement of operations is based on awards ultimately expected to vest, it can be reduced for estimated forfeitures. The ASC topic Stock Compensation requires forfeitures to be estimated at the time of grant and revised, if necessary, in subsequent periods if actual forfeitures differ from those estimates. The share-based compensation charged against income for the periods ended December&amp;#160;31, 2020, 2019 and 2018 was $420,648, $756,596 and $415,615, respectively. The 2019 amount includes $675,000 of equity-based compensation issued from a subsidiary for director fees.&lt;/div&gt;&lt;/div&gt;&lt;div style="color: rgb(0, 0, 0); font-family: 'times new roman'; font-style: normal; font-variant-ligatures: normal; font-variant-caps: normal; font-weight: 400; letter-spacing: normal; orphans: 2; text-align: start; text-transform: none; white-space: normal; widows: 2; word-spacing: 0px; -webkit-text-stroke-width: 0px; text-decoration-thickness: initial; text-decoration-style: initial; text-decoration-color: initial; margin-top: 12pt; margin-bottom: 0pt; text-indent: 9%; font-size: 10pt;"&gt;&lt;div style="font-family: &amp;quot;times new roman&amp;quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;"&gt;We did not grant stock options to employees or outside directors in 2020, 2019 or 2018. If options were granted, their values would be determined using the Black-Scholes-Merton option-pricing model, which values options based on the stock price at the grant date, the expected life of the option, the estimated volatility of the stock, the expected dividend payments, and the risk-free interest rate over the life of the option.&lt;/div&gt;&lt;/div&gt;&lt;div style="color: rgb(0, 0, 0); font-family: 'times new roman'; font-style: normal; font-variant-ligatures: normal; font-variant-caps: normal; font-weight: 400; letter-spacing: normal; orphans: 2; text-align: start; text-transform: none; white-space: normal; widows: 2; word-spacing: 0px; -webkit-text-stroke-width: 0px; text-decoration-thickness: initial; text-decoration-style: initial; text-decoration-color: initial; margin-top: 12pt; margin-bottom: 0pt; text-indent: 9%; font-size: 10pt;"&gt;&lt;div style="font-family: &amp;quot;times new roman&amp;quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;"&gt;The Black-Scholes-Merton option pricing model was developed for estimating the fair value of traded options that have no vesting restrictions and are fully transferable. Because option valuation models require the use of subjective assumptions, changes in these assumptions can materially affect the fair value of the options.

A &amp;#8220;cuota&amp;#8221; is a unit of equity interest under Panamanian law, and the value of the CARs will be determined based upon the appreciation, if any, in the value of the cuotas of Oceanica Resources, S. de R.L., a Panamanian sociedad de responsabilidad limitada (&amp;#8220;Oceanica&amp;#8221;), after the award of such CARs. The Company indirectly holds a majority stake in Oceanica.&lt;/div&gt;&lt;/div&gt;&lt;div style="color: rgb(0, 0, 0); font-family: 'times new roman'; font-style: normal; font-variant-ligatures: normal; font-variant-caps: normal; font-weight: 400; letter-spacing: normal; orphans: 2; text-align: start; text-transform: none; white-space: normal; widows: 2; word-spacing: 0px; -webkit-text-stroke-width: 0px; text-decoration-thickness: initial; text-decoration-style: initial; text-decoration-color: initial; margin-top: 12pt; margin-bottom: 0pt; text-indent: 9%; font-size: 10pt;"&gt;&lt;div style="font-family: &amp;quot;times new roman&amp;quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;"&gt;The Board authorized the award of up to 750,000 CARs under the Key Employee Plan and the award of up to 600,000 CARs under the Director Plan. The terms of any CARs awarded under the Cuota Plans will be set forth in an award agreement between the Company and each participant, and the award agreement will set forth a vesting schedule for the CARs. In general, unvested CARs will be forfeited upon a participant&amp;#8217;s separation of service from the Company, and all vested and unvested CARs will be forfeited upon a participant&amp;#8217;s separation of service from the Company for &amp;#8220;cause&amp;#8221; (as defined in the Cuota Plans).&lt;/div&gt;&lt;/div&gt;&lt;div style="color: rgb(0, 0, 0); font-family: 'times new roman'; font-style: normal; font-variant-ligatures: normal; font-variant-caps: normal; font-weight: 400; letter-spacing: normal; orphans: 2; text-align: start; text-transform: none; white-space: normal; widows: 2; word-spacing: 0px; -webkit-text-stroke-width: 0px; text-decoration-thickness: initial; text-decoration-style: initial; text-decoration-color: initial; margin-top: 12pt; margin-bottom: 0pt; text-indent: 9%; font-size: 10pt;"&gt;&lt;div style="font-family: &amp;quot;times new roman&amp;quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;"&gt;Each participant in the Cuota Plans will be entitled to be paid the value of such participant&amp;#8217;s CARs upon the occurrence of a &amp;#8220;payment event.&amp;#8221; As used in the Cuota Plans, payment events consist of a change in control of the Company or the date specified in the applicable award agreement and, in the case of the Key Employee Plan, a separation of service without cause and the participant&amp;#8217;s continuous employment with the Company until the date specified in the applicable award agreement. The value of CARs liability will be based upon the difference between the basis in the cuotas of Oceanica on the date of the award of the CARs, which is $3.00, and the fair value of the cuotas on the date used for the payment event, in each case as determined by the Board in accordance with the provisions of the Cuota Plans. The fair value of the cuota as of August&amp;#160;31, 2019 was $1.00.

We evaluated the transaction under ASU &lt;div style="white-space: nowrap; letter-spacing: 0px; top: 0px;;display:inline;"&gt;2017-01&lt;/div&gt; Business Combinations (Topic 805) and determined that Bismarck did not meet the definition of a business so the transaction represented an acquisition of assets rather than a business combination. Asset acquisitions do not give rise to goodwill. Rather, the sum of the fair value of the consideration given, together with transaction costs is allocated to the individual assets acquired and liabilities assumed based on their relative fair values which were more clearly evident and, thus, more reliably measurable at the date of acquisition under ASC &lt;div style="white-space: nowrap; letter-spacing: 0px; top: 0px;;display:inline;"&gt;&lt;div style="white-space: nowrap; letter-spacing: 0px; top: 0px;;display:inline;"&gt;&lt;div style="white-space: nowrap; letter-spacing: 0px; top: 0px;;display:inline;"&gt;805-50-30-2&lt;/div&gt;&lt;/div&gt;&lt;/div&gt; &lt;div style="font-style:italic;display:inline;;font-style:italic;display:inline;"&gt;Initial Measurement&lt;/div&gt;.

Per ASC &lt;div style="white-space: nowrap; letter-spacing: 0px; top: 0px;;display:inline;"&gt;&lt;div style="white-space: nowrap; letter-spacing: 0px; top: 0px;;display:inline;"&gt;&lt;div style="white-space: nowrap; letter-spacing: 0px; top: 0px;;display:inline;"&gt;350-30-35-3,&lt;/div&gt;&lt;/div&gt;&lt;/div&gt; management has deemed the rights to this license to have an indefinite life. Determining if the rights to the license has an indefinite or finite life required us to consider the nature of the renewal process and any additional economic factors, if any, required when renewing this license. We currently expect to use and renew the related license indefinitely, and we do not believe there are currently any legal, regulatory, or contractual provisions that are expected to limit the useful life of the related exploration license or indicate that the useful life is other than indefinite. The exploration license is also not dependent on, or specifically associated with, another asset or group of assets that would limit the useful life of the intangible asset or indicate that the useful life is other than indefinite. Management&amp;#8217;s assumptions regarding our ability to successfully renew or extend the exploration license are based on Bismarck&amp;#8217;s historical experience. Bismarck was established in 2006, and they have historically renewed and extended the exploration license without a lapse in their ability to use the license. The license has also never been revoked. We will not incur significant maintenance costs related to the license. There is an annual fee due of approximately $14,000 to maintain the license. This amount is much less than the carrying amount of the license and the cost is not expected to prohibit continued renewals of the license in the future. Based on all the factors considered above, management believes it is appropriate to assign indefinite useful life to the acquisition of the rights for the exploration license. &lt;/div&gt;&lt;table border="0" style="width:100%; table-layout:fixed;" cellspacing="0" cellpadding="0"&gt;&lt;tr&gt;&lt;td&gt;&lt;/td&gt;&lt;/tr&gt;&lt;/table&gt;</omex:ExplorationLicenseTextBlock>

The financial statements and notes are representations of the Company&#8217;s management who are responsible for their integrity and objectivity and have prepared them in accordance with our customary accounting practices. </div></div><div style="font-family: times new roman; font-size: 10pt; margin-top: 18pt; margin-bottom: 0pt;"><div style="font-family: &quot;times new roman&quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;"><div style="font-weight:bold;display:inline;">Recent Accounting Pronouncements </div></div></div><div style="font-family: times new roman; font-size: 10pt; margin-top: 6pt; margin-bottom: 0pt;"><div style="font-family: &quot;times new roman&quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;"><div style="font-weight:bold;display:inline;"><div style="font-style:italic;display:inline;;font-style:italic;display:inline;">Accounting standards not yet applied </div></div></div></div><div style="text-indent: 9%; font-family: times new roman; font-size: 10pt; margin-top: 6pt; margin-bottom: 0pt;">In August 2020, the FASB issued Accounting Standards Update (ASU) <div style="white-space: nowrap; letter-spacing: 0px; top: 0px;;display:inline;">No.&#160;2020-06,</div> Debt-Debt with Conversion and Other Options (Subtopic <div style="white-space: nowrap; letter-spacing: 0px; top: 0px;;display:inline;">470-20)</div> and Derivatives and Hedging-Contracts in Entity&#8217;s Own Equity (Subtopic <div style="white-space: nowrap; letter-spacing: 0px; top: 0px;;display:inline;">815-40).</div> The amendments in this Update are effective for public business entities that meet the definition of a Securities and Exchange Commission (SEC) filer, excluding entities eligible to be smaller reporting companies as defined by the SEC, for fiscal years beginning after December&#160;15, 2021, including interim periods within those fiscal years. For all other entities, the amendments are effective for fiscal years beginning after December&#160;15, 2023, including interim periods within those fiscal years. Early adoption is permitted, but no earlier than fiscal years beginning after December&#160;15, 2020, including interim periods within those fiscal years. The Board specified that an entity should adopt the guidance as of the beginning of its annual fiscal year. </div><div style="text-indent: 9%; font-family: times new roman; font-size: 10pt; margin-top: 12pt; margin-bottom: 0pt;"><div style="font-family: &quot;times new roman&quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;">The amendments in the above Update affect entities that issue convertible instruments and/or contracts in an entity&#8217;s own equity. For convertible instruments, the instruments primarily affected are those issued with beneficial conversion features or cash conversion features because the accounting models for those specific features are removed. However, all entities that issue convertible instruments are affected by the amendments to the disclosure requirements in this Update. For contracts in an entity&#8217;s own equity, the contracts primarily affected are freestanding instruments and embedded features that are accounted for as derivatives under the current guidance because of failure to meet the settlement conditions of the derivatives scope exception related to certain requirements of the settlement assessment. The Board simplified the settlement assessment by removing the requirements (1)&#160;to consider whether the contract would be settled in registered shares, (2)&#160;to consider whether collateral is required to be posted, and (3)&#160;to assess shareholder rights. Those amendments also affect the assessment of whether an embedded conversion feature in a convertible instrument qualifies for the derivatives scope exception. Additionally, the amendments in this Update affect the diluted EPS calculation for instruments that may be settled in cash or shares and for convertible instruments. The Company has not elected early adoption of this ASU. </div></div><div style="text-indent: 9%; font-family: times new roman; font-size: 10pt; margin-top: 12pt; margin-bottom: 0pt;">On October 31, 2018, the SEC adopted a final rule (&#8220;New Final Rule&#8221;) that will replace SEC&#160;Industry&#160;Guide&#160;7&#160;with new disclosure requirements that are more closely aligned with current industry and global regulatory practices and standards, including NI <div style="white-space: nowrap; letter-spacing: 0px; top: 0px;;display:inline;">43-101.</div> Companies must comply with the New Final Rule for the company&#8217;s first fiscal year beginning on or after January&#160;1, 2021. While early voluntary compliance with the New Final Rule is permitted, we have not elected early adoption of this New Final Rule at this time. </div><div style="text-indent: 9%; font-family: times new roman; font-size: 10pt; margin-top: 12pt; margin-bottom: 0pt;"><div style="font-family: &quot;times new roman&quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;">Other recent accounting pronouncements issued by the FASB, the AICPA and the SEC did not or are not believed by management to have a material effect, if any, on the Company&#8217;s financial statements. </div></div><div style="font-family: times new roman; font-size: 10pt; margin-top: 18pt; margin-bottom: 0pt;"><div style="font-family: &quot;times new roman&quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;"><div style="font-weight:bold;display:inline;">Principles of Consolidation </div></div></div><div style="text-indent: 9%; font-family: times new roman; font-size: 10pt; margin-top: 6pt; margin-bottom: 0pt;">The consolidated financial statements include the accounts of the Company and its direct and indirect wholly owned subsidiaries, both domestic and international. Equity investments in which we exercise significant influence but do not control and of which we are not the primary beneficiary are accounted for using the equity method. All significant inter-company and intra-company transactions and balances have been eliminated. The results of operations attributable to the <div style="white-space: nowrap; letter-spacing: 0px; top: 0px;;display:inline;">non-controlling</div> interest are presented within equity and net income and are shown separately from the Company&#8217;s equity and net income attributable to the Company. Some of the existing inter-company balances, which are eliminated upon consolidation, include features allowing the liability to be converted into equity of a subsidiary, which if exercised, could increase the direct or indirect interest of the Company in the <div style="white-space: nowrap; letter-spacing: 0px; top: 0px;;display:inline;">non-wholly</div> owned subsidiaries. </div><div style="font-family: times new roman; font-size: 10pt; margin-top: 18pt; margin-bottom: 0pt;"><div style="font-family: &quot;times new roman&quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;"><div style="font-weight:bold;display:inline;">Use of Estimates </div></div></div><div style="text-indent: 9%; font-family: times new roman; font-size: 10pt; margin-top: 6pt; margin-bottom: 0pt;"><div style="font-family: &quot;times new roman&quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;">Management uses estimates and assumptions in preparing these consolidated financial statements in accordance with U.S. GAAP. Those estimates and assumptions affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities, and the reported revenues and expenses. Actual results could vary from the estimates that were used. </div></div><div style="font-family: times new roman; font-size: 10pt; margin-top: 18pt; margin-bottom: 0pt;"><div style="font-family: &quot;times new roman&quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;"><div style="font-weight:bold;display:inline;">Revenue Recognition and Accounts Receivable </div></div></div><div style="text-indent: 9%; font-family: times new roman; font-size: 10pt; margin-top: 6pt; margin-bottom: 0pt;">As of January&#160;1, 2019, the Company adopted the Financial Accounting Standards Board (FASB) Accounting Standards Update <div style="white-space: nowrap; letter-spacing: 0px; top: 0px;;display:inline;">No.&#160;2014-09,</div> Revenue from Contracts with Customers (Topic 606), as modified (ASU <div style="white-space: nowrap; letter-spacing: 0px; top: 0px;;display:inline;">No.&#160;2014-09),</div> using the modified retrospective method. This method requires that any financial statement impact from adoption be recognized as a cumulative adjustment to retained earnings as of the date of adoption. The adoption of this ASU did not change the timing of the Company&#8217;s revenue recognition for any contracts and, therefore, the adoption of this standard did not have a material impact on the Company&#8217;s financial statements. </div><div style="text-indent: 9%; font-family: times new roman; font-size: 10pt; margin-top: 12pt; margin-bottom: 0pt;"><div style="font-family: &quot;times new roman&quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;">Revenue is recognized when a customer obtains control of promised goods or services, in an amount that reflects the consideration which the Company expects to receive in exchange for those goods or services. To determine revenue recognition for arrangements that the Company determines are within the scope of ASC Topic 606, the Company performs the following five steps: (i)&#160;identify the contract(s) with a customer; (ii)&#160;identify the performance obligations in the contract; (iii)&#160;determine the transaction price; (iv)&#160;allocate the transaction price to the performance obligations in the contract; and (v)&#160;recognize revenue when (or as) the Company satisfies a performance obligation. The Company only applies the five-step model to contracts when it is probable that the Company will collect the consideration it is entitled to in exchange for the goods or services it transfers to the customer. At contract inception, once the contract is determined to be within the scope of ASC Topic 606, the Company assesses the goods or services promised within each contract and determines those that are performance obligations and assesses whether each promised good or service is distinct. The Company then recognizes as revenue the amount of the transaction price that is allocated to the respective performance obligation when (or as) the performance obligation is satisfied. Sales, value add, and other taxes collected on behalf of third parties are excluded from revenue. </div></div><div style="text-indent: 9%; font-family: times new roman; font-size: 10pt; margin-top: 12pt; margin-bottom: 0pt;"><div style="font-family: &quot;times new roman&quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;">The Company currently generates revenues from four customers with contracts. There are two sources of revenue, marine services, and other services. The contracts for both services provide research, scientific services, marine operations planning, management execution, and project management. These services are billed generally on a monthly basis and recognized as revenue as the services are performed. Revenue is recognized at a point in time as services are provided, as the customers simultaneously receive and consume the benefits provided by the Company each month. The Company generally does not receive any upfront consideration for these services, and there is no variable consideration for the services.&#160;Costs associated with both services include all direct consulting labor, and minimal supplies, and is charged to operations as a component of Operations and Research. </div></div><div style="text-indent: 9%; font-family: times new roman; font-size: 10pt; margin-top: 12pt; margin-bottom: 0pt;"><div style="font-family: &quot;times new roman&quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;">Accounts receivable are based on amounts billed to customers. Generally accepted accounting principles state an estimate is to be made for an allowance for doubtful accounts. We have determined no allowance is currently necessary. If we were to have a recorded allowance, the accounts receivable would be stated net of the recorded allowance. </div></div><div style="font-family: times new roman; font-size: 10pt; margin-top: 18pt; margin-bottom: 0pt;"><div style="font-family: &quot;times new roman&quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;"><div style="font-weight:bold;display:inline;">Cash and Cash Equivalents </div></div></div><div style="text-indent: 9%; font-family: times new roman; font-size: 10pt; margin-top: 6pt; margin-bottom: 0pt;"><div style="font-family: &quot;times new roman&quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;">Cash and cash equivalents and restricted cash include cash on hand and cash in banks. We also consider all highly liquid investments with a maturity of three months or less when purchased to be cash equivalents, of which we do not have any. </div></div><div style="font-family: times new roman; font-size: 10pt; margin-top: 18pt; margin-bottom: 0pt;"><div style="font-family: &quot;times new roman&quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;"><div style="font-weight:bold;display:inline;">Exploration License </div></div></div><div style="text-indent: 9%; font-family: times new roman; font-size: 10pt; margin-top: 6pt; margin-bottom: 0pt;"><div style="font-family: &quot;times new roman&quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;">The Company follows the guidance pursuant to ASU 350, &#8220;<div style="font-style:italic;display:inline;;font-style:italic;display:inline;">Intangibles-Goodwill and Other</div>&#8221; in accounting for its Exploration License. Management determined the rights to use the license to have an indefinite life. This assessment is based on the historical success of renewing the license since 2006, and the fact that management believes there are no legal, regulatory, or contractual provisions that would limit the useful life of the asset. The exploration license is not dependent on another asset or group of assets that could potentially limit the useful life of the exploration license. In the future, the recoverability of the license will be tested whenever circumstances indicate that its carrying amount may not recoverable per the guidance of the Accounting Standards Codification (&#8220;ASC&#8221;) for topic 360 for Property, Plant and Equipment<div style="font-style:italic;display:inline;;font-style:italic;display:inline;">.</div> </div></div><div style="font-family: times new roman; font-size: 10pt; margin-top: 18pt; margin-bottom: 0pt;"><div style="font-family: &quot;times new roman&quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;"><div style="font-weight:bold;display:inline;">Long-Lived Assets </div></div></div><div style="text-indent: 9%; font-family: times new roman; font-size: 10pt; margin-top: 6pt; margin-bottom: 0pt;"><div style="font-family: &quot;times new roman&quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;">Our policy is to recognize impairment losses relating to long-lived assets in accordance with the ASC 360 Property, Plant and Equipment. Decisions are based on several factors, including, but not limited to, management&#8217;s plans for future operations, recent operating results and projected cash flows. Impairment losses are included in depreciation at the time of impairment. We did not have any impairments in 2020, 2019 or 2018. </div></div><div style="font-family: times new roman; font-size: 10pt; margin-top: 18pt; margin-bottom: 0pt;"><div style="font-family: &quot;times new roman&quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;"><div style="font-weight:bold;display:inline;">Property and Equipment and Depreciation </div></div></div><div style="text-indent: 9%; font-family: times new roman; font-size: 10pt; margin-top: 6pt; margin-bottom: 0pt;"><div style="font-family: &quot;times new roman&quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;">Property and equipment is stated at historical cost. Depreciation is calculated using the straight-line method at rates based on the assets&#8217; estimated useful lives which are normally between three and thirty years. Leasehold improvements are amortized over their estimated useful lives or lease term, if shorter. Items that may require major overhauls (such as engines or generators) that enhance or extend the useful life of vessel related assets qualify to be capitalized and depreciated over the useful life or remaining life of that asset, whichever was shorter. Certain major repair items required by industry standards to ensure a vessel&#8217;s seaworthiness also qualified to be capitalized and depreciated over the period of time until the next scheduled planned major maintenance for that item. All other repairs and maintenance were accounted for under the direct-expensing method and are expensed when incurred. </div></div><div style="font-family: times new roman; font-size: 10pt; margin-top: 18pt; margin-bottom: 0pt;"><div style="font-family: &quot;times new roman&quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;"><div style="font-weight:bold;display:inline;">Earnings Per Share </div></div></div><div style="text-indent: 9%; font-family: times new roman; font-size: 10pt; margin-top: 6pt; margin-bottom: 0pt;">Basic earnings per share (&#8220;EPS&#8221;) is computed by dividing income available to common stockholders by the weighted-average number of common shares outstanding for the period. In periods when the Company has income, the Company would calculate basic earnings per share using the <div style="white-space: nowrap; letter-spacing: 0px; top: 0px;;display:inline;">two-class</div> method, if required, pursuant to ASC 260 <div style="font-style:italic;display:inline;;font-style:italic;display:inline;">Earnings Per Share.</div> The <div style="white-space: nowrap; letter-spacing: 0px; top: 0px;;display:inline;">two-class</div> method was required effective with the issuance of certain senior convertible notes in the past because these notes qualified as a participating security, giving the holder the right to receive dividends should dividends be declared on common stock. Under the <div style="white-space: nowrap; letter-spacing: 0px; top: 0px;;display:inline;">two-class</div> method, earnings for a period are allocated on a pro rata basis to the common stockholders and to the holders of convertible notes based on the weighted average number of common shares outstanding and number of shares that could be issued upon conversion. The Company does not use the <div style="white-space: nowrap; letter-spacing: 0px; top: 0px;;display:inline;">two-class</div> method in periods when it generates a loss because the holder of the convertible notes does not participate in losses. Currently, we do not have any outstanding convertible notes that qualify as a participating security. </div><div style="text-indent: 9%; font-family: times new roman; font-size: 10pt; margin-top: 12pt; margin-bottom: 0pt;">Diluted EPS reflects the potential dilution that would occur if dilutive securities and other contracts to issue common stock were exercised or converted into common stock or resulted in the issuance of common stock that then shared in our earnings. We use the treasury stock method to compute potential common shares from stock options and warrants and the <div style="white-space: nowrap; letter-spacing: 0px; top: 0px;;display:inline;">if-converted</div> method to compute potential common shares from preferred stock, convertible notes or other convertible securities. For diluted earnings per share, the Company uses the more dilutive of the <div style="white-space: nowrap; letter-spacing: 0px; top: 0px;;display:inline;">if-converted</div> method or <div style="white-space: nowrap; letter-spacing: 0px; top: 0px;;display:inline;">two-class</div> method. When a net loss occurs, potential common shares have an anti-dilutive effect on earnings per share and such shares are excluded from the diluted EPS calculation. </div><div style="text-indent: 9%; font-family: times new roman; font-size: 10pt; margin-top: 12pt; margin-bottom: 0pt;"><div style="font-family: &quot;times new roman&quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;">At December&#160;31, 2020, 2019 and 2018 the weighted average common shares outstanding were 10,538,114, 9,346,213 and 8,583,795, respectively. For the periods ending December&#160;31, 2020, 2019 and 2018 in which net losses occurred, all potential common shares were excluded from Diluted EPS because the effect of including such shares would be anti-dilutive. </div></div><div style="text-indent: 9%;

Accordingly, our financial instruments consist of cash and cash equivalents, accounts receivable, accounts payable, accrued liabilities, derivative financial instruments and mortgage and loans payable. We carry cash and cash equivalents, accounts payable and accrued liabilities, and mortgage and loans payable at the approximate fair market value, and, accordingly, these estimates are not necessarily indicative of the amounts that we could realize in a current market exchange. We carry derivative financial instruments at fair value as is required under current accounting standards. </div></div><div style="text-indent: 9%; font-family: times new roman; font-size: 10pt; margin-top: 12pt; margin-bottom: 0pt;">Derivative financial instruments consist of financial instruments or other contracts that contain a notional amount and one or more underlying variables (e.g., interest rate, security price or other variable), require no initial net investment and permit net settlement. Derivative financial instruments may be free-standing or embedded in other financial instruments. Further, derivative financial instruments are initially, and subsequently, measured at fair value and recorded as liabilities or, in rare instances, assets. We generally do not use derivative financial instruments to hedge exposures to cash-flow, market or foreign-currency risks. However, we have entered into certain other financial instruments and contracts with features that are either (i)&#160;not afforded equity classification, (ii)&#160;embody risks not clearly and closely related to host contracts, or (iii)&#160;may be <div style="white-space: nowrap; letter-spacing: 0px; top: 0px;;display:inline;">net-cash</div> settled by the counterparty.

ASC Topic 820 defines fair value, established a framework for measuring fair value in accordance with accounting principles generally accepted in the United States and expands disclosures about fair value measurements. Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. ASC Topic 820 established a three-tier fair value hierarchy which prioritizes the inputs used in measuring fair value. </div></div><div style="text-indent: 9%; font-family: times new roman; font-size: 10pt; margin-top: 12pt; margin-bottom: 0pt;"><div style="font-family: &quot;times new roman&quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;">The hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (level 1 measurements) and the lowest priority to unobservable inputs (level 3 measurements).

We evaluated the transaction under ASU <div style="white-space: nowrap; letter-spacing: 0px; top: 0px;;display:inline;">2017-01</div> Business Combinations (Topic 805) and determined that Bismarck did not meet the definition of a business so the transaction represented an acquisition of assets rather than a business combination. Asset acquisitions do not give rise to goodwill. Rather, the sum of the fair value of the consideration given, together with transaction costs is allocated to the individual assets acquired and liabilities assumed based on their relative fair values which were more clearly evident and, thus, more reliably measurable at the date of acquisition under ASC <div style="white-space: nowrap; letter-spacing: 0px; top: 0px;;display:inline;"><div style="white-space: nowrap; letter-spacing: 0px; top: 0px;;display:inline;"><div style="white-space: nowrap; letter-spacing: 0px; top: 0px;;display:inline;">805-50-30-2</div></div></div> <div style="font-style:italic;display:inline;;font-style:italic;display:inline;">Initial Measurement</div>.

font-family: times new roman; font-size: 10pt; margin-top: 12pt; margin-bottom: 0pt;">Included in this acquisition are the rights to Bismarck&#8217;s exploration license, which is renewable every two years. Per ASC <div style="white-space: nowrap; letter-spacing: 0px; top: 0px;;display:inline;"><div style="white-space: nowrap; letter-spacing: 0px; top: 0px;;display:inline;"><div style="white-space: nowrap; letter-spacing: 0px; top: 0px;;display:inline;">350-30-35-3,</div></div></div> management has deemed the rights to this license to have an indefinite life. Determining if the rights to the license has an indefinite or finite life required us to consider the nature of the renewal process and any additional economic factors, if any, required when renewing this license. We currently expect to use and renew the related license indefinitely, and we do not believe there are currently any legal, regulatory, or contractual provisions that are expected to limit the useful life of the related exploration license or indicate that the useful life is other than indefinite. The exploration license is also not dependent on, or specifically associated with, another asset or group of assets that would limit the useful life of the intangible asset or indicate that the useful life is other than indefinite. Management&#8217;s assumptions regarding our ability to successfully renew or extend the exploration license are based on Bismarck&#8217;s historical experience. Bismarck was established in 2006, and they have historically renewed and extended the exploration license without a lapse in their ability to use the license. The license has also never been revoked. We will not incur significant maintenance costs related to the license. There is an annual fee due of approximately $14,000 to maintain the license. This amount is much less than the carrying amount of the license and the cost is not expected to prohibit continued renewals of the license in the future. Based on all the factors considered above, management believes it is appropriate to assign indefinite useful life to the acquisition of the rights for the exploration license. </div><table border="0" style="width:100%; table-layout:fixed;" cellspacing="0" cellpadding="0"><tr><td></td></tr></table><span></span>

These preferred shares are convertible into an aggregate of 261,200 shares of Class&#160;B <div style="white-space: nowrap; letter-spacing: 0px; top: 0px;;display:inline;">non-voting</div> common stock. Our holdings now constitute an approximate 14% ownership in NMI. At December&#160;31, 2020, our estimated share of unrecognized NMI equity-method losses is approximately $21.3&#160;million. We have not recognized the accumulated $21.3&#160;million in our income statement because these losses exceeded our investment in NMI. Our investment has a carrying value of zero as a result of the recognition of our share of prior losses incurred by NMI under the equity method of accounting. We believe it is appropriate to allocate this loss carryforward of $21.3&#160;million to any incremental NMI investment that may be recognized on our balance sheet in excess of zero since the losses occurred when they were an equity-method investment. The aforementioned loss carryforward is based on NMI&#8217;s last unaudited financial statements as of December&#160;31, 2016. We do not believe losses NMI may have incurred subsequent to the December&#160;31, 2016 audit to be material. We do not have any financial obligations to NMI, and we are not committed to provide financial support to NMI. </div><div style="text-indent: 9%; font-family: times new roman; font-size: 10pt; margin-top: 12pt; margin-bottom: 0pt;"><div style="font-family: &quot;times new roman&quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;">Although we are a shareholder of NMI, we have no representation on the board of directors or in management of NMI and do not hold any Class&#160;A voting shares. We are not involved in the management of NMI nor do we participate in their policy-making. Accordingly, we are not the primary beneficiary of NMI. As of December&#160;31, 2020, the net carrying value of our investment in NMI was zero in our consolidated financial statements. </div></div><div style="font-family: times new roman; font-size: 10pt; margin-top: 18pt; margin-bottom: 0pt;"><div style="font-family: &quot;times new roman&quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;"><div style="font-weight:bold;display:inline;"><div style="font-style:italic;display:inline;;font-style:italic;display:inline;">Chatham Rock Phosphate, Limited. </div></div></div></div><div style="text-indent: 9%; font-family: times new roman; font-size: 10pt; margin-top: 6pt; margin-bottom: 0pt;">During 2012, we performed <div style="white-space: nowrap; letter-spacing: 0px; top: 0px;;display:inline;">deep-sea</div> mining exploratory services for Chatham Rock Phosphate, Ltd. (&#8220;CRP&#8221;) valued at $1,680,000. As payment for these services, CRP issued 9,320,348 ordinary shares to us. During March 2017, Antipodes Gold Limited completed the acquisition of CRP. The surviving entity is now named Chatham Rock Phosphate Limited (&#8220;CRPL&#8221;). In exchange for our 9,320,348 shares of CRP we received 141,884 shares of CPRL, which represents equity ownership of, at most, approximately 1% of the surviving entity. Since CRP was a thinly traded stock and pursuant to guidance per ASC 320: <div style="font-style:italic;display:inline;;font-style:italic;display:inline;">Debt and Equity Securities</div> regarding readily determinable fair value, we believe it was appropriate to not recognize this amount as an asset nor as revenue during that period. We continue to carry the value of our investment in CPRL at zero in our consolidated financial statements. </div><div style="font-family: times new roman; font-size: 10pt; margin-top: 18pt; margin-bottom: 0pt;"><div style="font-family: &quot;times new roman&quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;"><div style="font-weight:bold;display:inline;"><div style="font-style:italic;display:inline;;font-style:italic;display:inline;">CIC, LLC </div></div></div></div><div style="text-indent: 9%; font-family: times new roman; font-size: 10pt; margin-top: 6pt; margin-bottom: 0pt;"><div style="font-family: &quot;times new roman&quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;">In 2018, we began providing services to CIC LLC, a company controlled by Greg Stemm, the past Chairman of the Board for Odyssey (See NOTE J for related parties). This company is pursuing deep water mining permits in foreign waters. Due to the initial structure of the company, we determined this venture to be a VIE consistent with ASU 2015-2. We have determined that we are not the primary beneficiary of the VIE and, therefore, we have not consolidated this entity. Additionally, we also will record the investment under the cost method as we have determined we do not exercise significant influence over the entity. We will assess our investment for impairment annually and, if a loss in value is deemed other than temporary, an impairment charge will be recorded. At December&#160;31, 2020, the accumulated investment in the entity is $2,370,794, which is classified as an investment in unconsolidated entity in our consolidated balance sheets. The original agreements relating to the equity investment were executed in January 2019. The original agreement was replaced in August of 2020 with a new agreement effective August&#160;1, 2020. </div></div><div style="text-indent: 9%; font-family: times new roman; font-size: 10pt; margin-top: 12pt; margin-bottom: 0pt;"><div style="font-family: &quot;times new roman&quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;">We account for the investments we make in certain legal entities in which equity investors do not have (1)&#160;sufficient equity at risk for the legal entity to finance its activities without additional subordinated financial support, or (2)&#160;as a group, the holders of the equity investment at risk do not have either the power, through voting or similar rights, to direct the activities of the legal entity that most significantly impact the entity&#8217;s economic performance, or (3)&#160;the obligation to absorb the expected losses of the legal entity or the right to receive expected residual returns of the legal entity. These legal entities are referred to as &#8220;variable interest entities&#8221; or &#8220;VIEs.&#8221; </div></div><div style="text-indent: 9%; font-family: times new roman; font-size: 10pt; margin-top: 12pt; margin-bottom: 0pt;"><div style="font-family: &quot;times new roman&quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;">We would consolidate the results of any such entity in which we determined we had a controlling financial interest. We would have a &#8220;controlling financial interest&#8221; in such an entity if we had both the power to direct the activities that most significantly affect the VIE&#8217;s economic performance and the obligation to absorb the losses of, or right to receive benefits from, the VIE that could be potentially significant to the VIE. On a quarterly basis, we reassess whether we have a controlling financial interest in any investments we have in these legal entities. </div></div><div style="font-size: 1px; margin-top: 12px; margin-bottom: 0px;"><div style="font-size: 1px; letter-spacing: 0px; top: 0px;;display:inline;">&#160;</div></div><div style="text-indent: 9%; font-family: times new roman; font-size: 10pt; margin-top: 0pt; margin-bottom: 0pt;"><div style="font-family: &quot;times new roman&quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;">We determine whether any of the entities in which we have made investments is a VIE at the start of each new venture and if a reconsideration event has occurred. At such times, we also consider whether we must consolidate a VIE and/or disclose information about our involvement in a VIE. A reporting entity must consolidate a VIE if that reporting entity has a variable interest (or combination of variable interests) that will absorb a majority of the VIE&#8217;s expected losses, receive a majority of the VIE&#8217;s expected residual returns, or both. A reporting entity must consider the rights and obligations conveyed by its variable interests and the relationship of its variable interests with variable interests held by other parties to determine whether its variable interests will absorb a majority of a VIE&#8217;s expected losses, receive a majority of the VIE&#8217;s expected residual returns, or both. The reporting entity that consolidates a VIE is called the primary beneficiary of that VIE. </div></div><table border="0" style="width:100%; table-layout:fixed;" cellspacing="0" cellpadding="0"><tr><td></td></tr></table><span></span>

The loan was issued in three tranches: (i) $5.0&#160;million (the &#8220;First Tranche&#8221;) was advanced upon execution of the Loan Agreement; (ii) $2.5&#160;million (the &#8220;Second Tranche&#8221;) was advanced on October&#160;1, 2014; and (iii) $2.5&#160;million (the &#8220;Third Tranche&#8221;) was advanced on December&#160;1, 2014. The Notes bear interest at a rate equal to 11% per annum. The Notes also contain an option whereby Monaco can purchase shares of Oceanica held by Odyssey (the &#8220;Share Purchase Option&#8221;) at a purchase price that is the lower of (a) $3.15 per share or (b)&#160;the price per share of a contemplated equity offering of Oceanica which totals $1.0&#160;million or more in the aggregate. The share purchase option was not clearly and closely related to the host debt agreement and required bifurcation. </div></div><div style="text-indent: 9%; font-family: times new roman; font-size: 10pt; margin-top: 12pt; margin-bottom: 0pt;">On December&#160;10, 2015, these promissory notes were amended as part of the asset acquisition agreement with Monaco (See NOTE R in our Form <div style="white-space: nowrap; letter-spacing: 0px; top: 0px;;display:inline;">10-K</div> filed with the Securities and Exchange Commission for the period ended December&#160;31, 2017 for further information). The amendment included the following material changes: (i) $2.2&#160;million of the indebtedness represented by the Notes was extinguished, (ii) $5.0&#160;million of the indebtedness represented by the Notes ceased to bear interest and is only repayable under certain circumstances from certain sources of cash, and (iii)&#160;the maturity date on the Notes was extended to December&#160;31, 2017. During March 2016, the maturity date was further extended to April&#160;1, 2018 and the exercise price of the Share Purchase Option was <div style="white-space: nowrap; letter-spacing: 0px; top: 0px;;display:inline;">re-priced</div> to $1.00 per share. This indebtedness has matured, but Monaco has not demanded payment because we are in negotiations with Monaco. As of the maturity date, the interest rate was adjusted to the default rate of 18% per annum. See &#8220;Loan Modification (March 2016)&#8221; below. For the twelve months ended December&#160;31, 2020 and 2019, interest expense in the amount of $574,680 and $573,110, respectively, was recorded. The outstanding interest-bearing balance of these Notes is $2.8&#160;million at December&#160;31, 2020 and 2019. </div><div style="font-family: &quot;times new roman&quot;; font-size: 10pt; margin-top: 18pt; margin-bottom: 0pt; line-height: 12pt;"><div style="font-family: &quot;times new roman&quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;"><div style="font-weight:bold;display:inline;">Note 2 &#8211; Monaco 2016 </div></div></div><div style="text-indent: 9%; font-family: times new roman; font-size: 10pt; margin-top: 6pt; margin-bottom: 0pt;">In March 2016, Monaco agreed to lend us an additional $1,825,000. These loan proceeds were received in full during the first quarter of 2016. The indebtedness bears interest at 10.0% percent per year. All principal and any unpaid interest was payable on April&#160;15, 2018. This indebtedness has matured, but Monaco has not demanded payment because we are in negotiations with Monaco. As of the maturity date, the interest rate was adjusted to the default rate of 18% per annum. The current outstanding balance as of December&#160;31, 2020 and 2019 was $1,175,000. The indebtedness is convertible at any time until the maturity date into shares of Oceanica held by us at a conversion price of $1.00 per share. Pursuant to this loan and as security for the indebtedness, Monaco was granted a second priority security interest in <div style="white-space: nowrap; letter-spacing: 0px; top: 0px;;display:inline;">(a)&#160;one-half</div> of the indebtedness evidenced by the Amended and Restated Consolidated Note and Guaranty, dated September&#160;25, 2015 (the &#8220;ExO Note&#8221;), in the original principal amount of $18.0&#160;million, issued by Exploraciones Oceanicas S. de R.L. de C.V. to Oceanica Marine Operations, S.R.L. (&#8220;OMO&#8221;), and all rights associated therewith (the &#8220;OMO Collateral&#8221;); and (b)&#160;all technology and assets in our possession or control used for offshore exploration, including an ROV system, <div style="white-space: nowrap; letter-spacing: 0px; top: 0px;;display:inline;">deep-tow</div> search systems, winches, multi-beam sonar, and other equipment. The carrying net book value of this equipment is less than $0.1&#160;million. We unconditionally and irrevocably guaranteed all obligations of ours and our subsidiaries to Monaco under this loan agreement. As further consideration for the loan, Monaco was granted an option (the &#8220;Option&#8221;) to purchase the OMO Collateral. The Option is exercisable at any time before the earlier of (a)&#160;the date that is 30 days after the loan is paid in full or (b)&#160;the maturity date of the ExO Note, for aggregate consideration of $9.3&#160;million, $1.8&#160;million of which would be paid at the closing of the exercise of the Option, with the balance paid in ten monthly installments of $750,000. During 2017, we sold a marine vessel to a related party of Monaco for $650,000.&#160;The consideration for this vessel was applied against our loan balance to Monaco in the amount of $650,000. </div><div style="font-family: times new roman; font-size: 10pt; margin-top: 18pt; margin-bottom: 0pt;"><div style="font-family: &quot;times new roman&quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;"><div style="font-weight:bold;display:inline;"><div style="font-style:italic;display:inline;;font-style:italic;display:inline;">Accounting considerations </div></div></div></div><div style="text-indent: 9%; font-family: times new roman; font-size: 10pt; margin-top: 6pt; margin-bottom: 0pt;"><div style="font-family: &quot;times new roman&quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;">ASC 815 generally requires the analysis of embedded terms and features that have characteristics of derivatives to be evaluated for bifurcation and separate accounting in instances where their economic risks and characteristics are not clearly and closely related to the risks of the host contract. The option to purchase the OMO Collateral is an embedded feature that is not clearly and closely related to the host debt agreement and thus requires bifurcation. Because the option is out of the money, it has no material fair value as of the inception date or currently. The debt agreement did not contain any additional embedded terms or features that have characteristics of derivatives. However, we were required to consider whether the hybrid contract embodied a beneficial conversion feature (&#8220;BCF&#8221;). The calculation of the effective conversion amount did result in a BCF because the effective conversion price was less than the market price on the date of issuance, therefore a BCF of $456,250 was recorded. This BCF has been fully amortized as of March&#160;31, 2018. A total of $252,940 has been previously charged to interest expense related to the discount. For the twelve months ended December&#160;31, 2020 and 2019, interest in the amount of $268,350 and $267,617, respectively, was recorded. </div></div><div style="text-indent: 9%; font-family: times new roman; font-size: 10pt; margin-top: 18pt; margin-bottom: 0pt;"><div style="font-family: &quot;times new roman&quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;"><div style="font-weight:bold;display:inline;"><div style="font-style:italic;display:inline;;font-style:italic;display:inline;">Loan modification (December 2015) </div></div></div></div><div style="text-indent: 9%; font-family: times new roman; font-size: 10pt; margin-top: 6pt; margin-bottom: 0pt;"><div style="font-family: &quot;times new roman&quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;">In connection with the Acquisition Agreement entered into with Monaco on December&#160;10, 2015, Monaco agreed to modify certain terms of the loans as partial consideration for the purchase of assets. For the First Tranche ($5,000,000 advanced on August&#160;14, 2014), Monaco agreed to cease interest as of December&#160;10, 2015 and reduce the loan balance by (i)&#160;the cash or other value received from the SS <div style="font-style:italic;display:inline;;font-style:italic;display:inline;">Central America</div> shipwreck project (&#8220;SSCA&#8221;) or (ii)&#160;if the proceeds received from the SSCA project were insufficient to pay off the loan balance by December&#160;31, 2017, then Monaco could seek repayment of the remaining outstanding balance on the loan by withholding Odyssey&#8217;s 21.25% &#8220;additional consideration&#8221; in new shipwreck projects performed for Monaco in the future. For the Second Tranche ($2,500,000 advanced on October&#160;1, 2014), Monaco agreed to reduce the principal amount by $2,200,000 leaving a new principal balance of $300,000 and extension of maturity to December&#160;31, 2017. For the Third Tranche ($2,500,000 advanced on December&#160;1, 2014), Monaco agreed to the extension of maturity to December&#160;31, 2017. </div></div><div style="text-indent: 9%; font-family: times new roman; font-size: 10pt; margin-top: 12pt; margin-bottom: 0pt;"><div style="font-family: &quot;times new roman&quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;">On December&#160;10, 2015, the Monaco call option related to the Oceanica shares held by us was extended until December&#160;31, 2017. </div></div><div style="text-indent: 9%; font-family: times new roman; font-size: 10pt; margin-top: 18pt; margin-bottom: 0pt;"><div style="font-family: &quot;times new roman&quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;"><div style="font-weight:bold;display:inline;"><div style="font-style:italic;display:inline;;font-style:italic;display:inline;">Loan modification (March 2016) </div></div></div></div><div style="text-indent: 9%; font-family: times new roman; font-size: 10pt; margin-top: 6pt; margin-bottom: 0pt;">In connection with the $1.825&#160;million loan agreement with Monaco in March 2016, the existing $2.8&#160;million notes were modified. Of the combined total indebtedness of Monaco&#8217;s Note 1 and Note 2, Monaco can convert this debt into 3,174,603 shares of Oceanica at a fixed conversion price of $1.00 per share, or $3,174,603. Any remaining debt in excess of $3,174,603 is not convertible. Additionally, the modification eliminated Monaco&#8217;s option (&#8220;share purchase option&#8221;) to purchase 3,174,603 shares of Oceanica stock at a price of $3.15 per share. The modification was analyzed under ASC 480 <div style="font-style:italic;display:inline;;font-style:italic;display:inline;">Distinguishing Liabilities from Equity</div> (&#8220;ASC 480&#8221;) to determine if extinguishment accounting was applicable.

(&#8220;MINOSA&#8221;) agreed to lend us up to $14.75&#160;million. The entire $14.75&#160;million was loaned in five advances from March&#160;11 through June&#160;30, 2015. The outstanding indebtedness bears interest at 8.0% percent per annum. The Promissory Note was amended on April&#160;10, 2015 and on October&#160;1, 2015 so that, unless otherwise converted as provided in the Note, the adjusted principal balance shall be due and payable in full upon written demand by MINOSA; provided that MINOSA agreed that it shall not demand payment of the adjusted principal balance earlier than the first to occur of: (i)&#160;30 days after the date on which (x)&#160;SEMARNAT makes a determination with respect to the current application for the Manifestacion de Impacto Ambiental relating to phosphate deposit project, which determination is other than an approval or (y)&#160;Odyssey Marine Enterprises or any of its affiliates withdraws such application without MINOSA&#8217;s prior written consent; (ii)&#160;termination by Odyssey of the Stock Purchase Agreement, dated March&#160;11, 2015 (the &#8220;Purchase Agreement&#8221;), among Odyssey, MINOSA, and Penelope Mining, LLC (the &#8220;Investor&#8221;); (iii)&#160;the occurrence of an event of default under the Promissory Note; (iv)&#160;December 31, 2015; or (v)&#160;if and only if the Investor shall have terminated the Purchase Agreement pursuant to Section&#160;8.1(d)(iii) thereof, March&#160;30, 2016. This indebtedness is classified as short-term debt. In connection with the loans, we granted MINOSA an option to purchase our 54% interest in Oceanica for $40.0&#160;million (the &#8220;Oceanica Call Option&#8221;). On March&#160;11, 2016, the Oceanica Call has expired. Completion of the transaction requires amending the Company&#8217;s articles of incorporation to (a)&#160;effect a reverse stock split, which was implemented on February&#160;19, 2016, (b)&#160;adjusting the Company&#8217;s authorized capitalization, which was also implemented on February&#160;19, 2016, and (c)&#160;establishing a classified board of directors (collectively, the &#8220;Amendments&#8221;). The Amendments have been or will be set forth in certificates of amendment to the Company&#8217;s articles of incorporation filed or to be filed with the Nevada Secretary of State. As collateral for the loan, we granted MINOSA a security interest in the Company&#8217;s 54% interest in Oceanica. The outstanding principal balance of this debt was $14.75&#160;million at December&#160;31, 2020 and 2019, respectively. The maturity date of this indebtedness has been amended and matured on March&#160;18, 2017. Per Note 6 MINOSA 2 below, the Minosa Purchase Agreement amended the due date of this note to a due date which may be no earlier than December&#160;31, 2017, that is at least 60 days subsequent to written notice that Minosa intends to demand payment. See Note 6 &#8211; MINOSA 2 for further qualifications. During December 2017, MINOSA transferred this debt to its parent company.

The Oceanica Call Option is considered a freestanding financial instrument because it is both (i)&#160;legally detachable and (ii)&#160;separately exercisable. The Oceanica Call Option did not fall under the guidance of ASC 480. Additionally, it did not meet the definition of a derivative under ASC 815 because the option has a fixed value of $40.0&#160;million and does not contain an underlying variable which is indicative of a derivative. This instrument is considered an option contract for a sale of an asset. The guidance applied in this case is ASC <div style="white-space: nowrap; letter-spacing: 0px; top: 0px;;display:inline;">360-20,</div> which provides that in situations when a party lends funds to a seller and is given an option to buy the property at a certain date in the future, the loan shall be recorded at its present value using market interest rates and any excess of the proceeds over that amount credited to an option deposit account. If the option is exercised, the deposit shall be included as part of the sales proceeds; if not exercised, it shall be credited to income in the period in which the option lapses. </div><div  style="font-size: 13.28px;

In pledge agreements related to the loans, we granted security interests to Epsilon in (a)&#160;the 54&#160;million cuotas (a unit of ownership under Panamanian law) of Oceanica Resources S. de R.L. (&#8220;Oceanica&#8221;) held by our wholly owned subsidiary, Odyssey Marine Enterprises, Ltd. (&#8220;OME&#8221;), (b)&#160;all notes and other receivables from Oceanica and its subsidiary owed to the Odyssey Pledgors, and (c)&#160;all of the outstanding equity in OME. Epsilon has the right to convert the outstanding indebtedness into shares of our common stock upon 75 days&#8217; notice to us or upon a merger, consolidation, third party tender offer, or similar transaction relating to us at the conversion price of $5.00 per share, which represents the <div style="white-space: nowrap; letter-spacing: 0px; top: 0px;;display:inline;">five-day</div> volume-weighted average price of Odyssey&#8217;s common stock for the five trading day period ending on March&#160;17, 2016. On January&#160;25, 2017, Epsilon provided notice to us that it would convert the initial $3.0&#160;million plus accrued interest per the Restated Note Purchase Agreement at $5.00 per share in accordance with the terms of the agreement. The conversion and issuance of new shares was effective April&#160;10, 2017 and included accrued interest of $302,274 for a total 670,455 shares. Upon the occurrence and during the continuance of an event of default, the conversion price was to be reduced to $2.50 per share. Following any conversion of the indebtedness, Penelope Mining LLC (an affiliate of Epsilon) (&#8220;Penelope&#8221;), may elect to reduce its commitment to purchase preferred stock of Odyssey under the Stock Purchase Agreement, dated as of March&#160;11, 2015 (as amended, the &#8220;Stock Purchase Agreement&#8221;), among Odyssey, Penelope, and Minera del Norte, S.A. de C.V.

However, we were required to consider whether the hybrid contract embodied a beneficial conversion feature (&#8220;BCF&#8221;). The calculation of the effective conversion amount did result in a BCF because the effective conversion price was less than the Company&#8217;s stock price on the date of issuance, therefore a BCF of $96,000 was recorded. The BCF represents a debt discount which was amortized over the life of the loan. </div></div><div style="text-indent: 9%; font-family: times new roman; font-size: 10pt; margin-top: 18pt; margin-bottom: 0pt;"><div style="font-family: &quot;times new roman&quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;"><div style="font-weight:bold;display:inline;"><div style="font-style:italic;display:inline;;font-style:italic;display:inline;">Loan modification (October 1, 2016) </div></div></div></div><div style="text-indent: 9%; font-family: times new roman; font-size: 10pt; margin-top: 6pt; margin-bottom: 0pt;">On October&#160;1, 2016 Odyssey Marine Enterprises, Ltd. (&#8220;OME&#8221;), entered into an Amended and Restated Note Purchase Agreement (the &#8220;Restated Note Purchase Agreement&#8221;) with Epsilon Acquisitions LLC (&#8220;Epsilon&#8221;). In connection with the existing $3.0&#160;million loan agreement, Epsilon agreed to lend an additional $3.0&#160;million evidenced by secured convertible promissory notes. The convertible promissory notes bear an interest rate of 10.0% per annum and are due and payable on March&#160;18, 2017. Epsilon has the right to convert all amounts outstanding under the Restated Note into shares of our common stock upon 75 days&#8217; notice to OME or upon a merger, consolidation, third party tender offer, or similar transaction relating to us at the applicable conversion price, which is (a)&#160;$5.00 per share with respect to the $3.0&#160;million already advanced under the Restated Note and (b)&#160;with respect to additional advances under the Restated Note, the <div style="white-space: nowrap; letter-spacing: 0px; top: 0px;;display:inline;">five-day</div> volume-weighted average price of our common stock for the five trading day period ending on the trading day immediately prior to the date on which OME submits a borrowing notice for such advance. Notwithstanding anything herein to the contrary, we shall not issue any of our common stock upon conversion of any outstanding tranche (other than the first $3.0&#160;million already advanced) under this Restated Note in excess of 1,388,769 shares of common stock.&#160;The additional tranches were issued as follows: (a) $1,000,000 (&#8220;Tranche 3&#8221;) was issued on October&#160;16, 2016 with a conversion price of $3.52 per share; (b) $1,000,000 (&#8220;Tranche 4&#8221;) was issued on November&#160;15, 2016 with a conversion price of $4.19 per share; and (c) $1,000,000 (&#8220;Tranche 5&#8221;) was issued on December&#160;15, 2016 with a conversion price of $4.13 per share. During 2017, Epsilon assigned Tranche 4 and 5 totaling $2,000,000 of this debt to MINOSA under the same terms as the original debt. See Note &#8211; MINOSA 2 below for further detail. </div><div style="text-indent: 9%; font-family: times new roman; font-size: 10pt; margin-top: 12pt; margin-bottom: 0pt;">As an inducement for the issuance of the additional $3.0&#160;million of promissory notes, we also delivered to Epsilon a common stock purchase warrant (the &#8220;Warrant&#8221;) pursuant to which Epsilon has the right to purchase up to 120,000 shares of our common stock at an exercise price of $3.52 per share, which exercise price represents the <div style="white-space: nowrap; letter-spacing: 0px; top: 0px;;display:inline;">five-day</div> volume-weighted average price of our common stock for the five trading day period ending on the trading day immediately prior to the day on which the Warrant was issued. Epsilon may exercise the Warrant in whole or in part at any time during the period ending October&#160;1, 2021. The Warrant includes a cashless exercise feature and provides that, if Epsilon is in default of its obligations to fund any advance pursuant to and in accordance with the Restated Note Purchase Agreement, then, thereafter, the maximum aggregate number of shares of common stock that may be purchased under the Warrant shall be the number determined by multiplying 120,000 by a fraction, (a)&#160;the numerator of which is the aggregate principal amount of advances that have been extended to the OME by Epsilon pursuant to the Restated Note Purchase Agreement on or after the date of the Warrant and prior to the date of such failure and (b)&#160;the denominator of which is $3.0&#160;million. During November 2020, Epsilon opted to exercise this warrant using the cashless exercise feature. This exercise resulted in the issuance of 56,228 of our common shares and the forfeiture of the right to acquire the remaining 63,772 common shares. </div><div style="text-indent: 9%; font-family: times new roman; font-size: 10pt; margin-top: 18pt; margin-bottom: 0pt;"><div style="font-family: &quot;times new roman&quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;"><div style="font-weight:bold;display:inline;"><div style="font-style:italic;display:inline;;font-style:italic;display:inline;">Accounting considerations for additional tranches </div></div></div></div><div style="text-indent: 9%; font-family: times new roman; font-size: 10pt; margin-top: 6pt; margin-bottom: 0pt;"><div style="font-family: &quot;times new roman&quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;">We evaluated for proper classification under ASC 480 <div style="font-style:italic;display:inline;;font-style:italic;display:inline;">Distinguishing Liabilities from Equity</div> (&#8220;ASC 480&#8221;), ASC 815 <div style="font-style:italic;display:inline;;font-style:italic;display:inline;">Derivatives and Hedging</div> (&#8220;ASC 815&#8221;) and ASC 320 <div style="font-style:italic;display:inline;;font-style:italic;display:inline;">Property, Plant and Equipment</div> (&#8220;ASC 320&#8221;).

For the twelve months ended December&#160;31, 2020 and 2019, interest in the amount of $90,136 and $100,272, respectively, was recorded. </div></div><div style="font-size: 1px; margin-top: 18px; margin-bottom: 0px;"><div style="font-size: 1px; letter-spacing: 0px; top: 0px;;display:inline;">&#160;</div></div><div style="text-indent: 9%; font-family: times new roman; font-size: 10pt; margin-top: 0pt; margin-bottom: 0pt;"><div style="font-family: &quot;times new roman&quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;"><div style="font-weight:bold;display:inline;"><div style="font-style:italic;display:inline;;font-style:italic;display:inline;">Term Extension (March 21, 2017) </div></div></div></div><div style="text-indent: 9%; font-family: times new roman; font-size: 10pt; margin-top: 6pt; margin-bottom: 0pt;"><div style="font-family: &quot;times new roman&quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;">On March&#160;21, 2017 we entered into an amendment to the Restated Note Purchase Agreement with Epsilon. In connection with the existing $6.0&#160;million of indebtedness, the adjusted principal balance is due and payable in full upon the earlier of (i)&#160;written demand by Epsilon or (ii)&#160;such time as Odyssey or the guarantor pays any other indebtedness for borrowed money prior to its stated maturity date. As such the Company amortized the notes up to their face value of $6,050,000 and they are classified as short-term. However, since Epsilon converted the first $3.0&#160;million into 670,455 of our common shares and assigned $2.0&#160;million to MINOSA, the current principal indebtedness at December&#160;31, 2020 and 2019 is $1.0&#160;million. </div></div><div style="font-family: times new roman; font-size: 10pt; margin-top: 18pt; margin-bottom: 0pt;"><div style="font-family: &quot;times new roman&quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;"><div style="font-weight:bold;display:inline;">Note 5 &#8211; SMOM </div></div></div><div style="text-indent: 9%; font-family: times new roman; font-size: 10pt; margin-top: 6pt; margin-bottom: 0pt;"><div style="font-family: &quot;times new roman&quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;">On May&#160;3, 2017, we entered into a Loan and Security Agreement (&#8220;Loan Agreement&#8221;) with SMOM. Pursuant to the Loan Agreement, SMOM agreed to loan us up to $3.0&#160;million as evidenced by a convertible promissory note. As a commitment fee, we assigned the remaining 50% of our Neptune Minerals, LLC receivable to SMOM. This receivable had zero carrying value on our balance sheet and due to the age and collectability was deemed to have no fair value. The indebtedness bears interest at a rate of 10% per annum and matures on the second anniversary of this Loan Agreement which is May&#160;3, 2019. During January 2020 this Loan Agreement was amended by increasing the interest rate to 18%. On April&#160;20, 2018, the loan was amended, and the principal amount of the Loan was increased to $3,500,000. The loan balance at December&#160;31, 2020 and 2019 is $3.5&#160;million. The holder has the option to convert up to $2.0&#160;million of any unpaid principal and interest into up to 50% of the equity interest held by Odyssey in Aldama Mining Company, S.de R.L. de C.V. which is a wholly owned subsidiary of ours. The conversion value of $1.0&#160;million equates to 10% of the equity interest in Aldama. If the holder elects to acquire the entire 50% of the 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&#160;million for each 10% of equity interests) during the period that is the later of (i)&#160;one year after the maturity date and (ii)&#160;one year after the loan is repaid in full, the expiration date. The lender may also choose to extend the expiration date annually by paying $500,000 for each year extended. For the twelve months ended December&#160;31, 2020 and 2019, interest in the amount of $350,958 and $349,999, respectively, was recorded. </div></div><div style="text-indent: 9%; font-family: times new roman; font-size: 10pt; margin-top: 18pt; margin-bottom: 0pt;"><div style="font-family: &quot;times new roman&quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;"><div style="font-weight:bold;display:inline;"><div style="font-style:italic;display:inline;;font-style:italic;display:inline;">Accounting considerations </div></div></div></div><div style="text-indent: 9%; font-family: times new roman; font-size: 10pt; margin-top: 6pt; margin-bottom: 0pt;"><div style="font-family: &quot;times new roman&quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;">We have accounted for this transaction as a financing transaction, wherein the net proceeds received were allocated to the financial instruments issued.

Pursuant to the Minosa Purchase Agreement, MINOSA agreed to loan Enterprises up to $3.0&#160;million. During 2017, we borrowed $2.7&#160;million against this facility and Epsilon assigned $2.0&#160;million of its debt to MINOSA. At December&#160;31, 2020 and 2019, the outstanding principal balance, including the Epsilon assignment, is $5.05&#160;million. The indebtedness is evidenced by a secured convertible promissory note (the &#8220;Minosa Note&#8221;) and bears interest at a rate equal to 10.0%&#160;per annum. Unless otherwise converted as described below, the entire outstanding principal balance under this Minosa Note and all accrued interest and fees are due and payable upon written demand by MINOSA; provided, that MINOSA agreed not make a demand for payment prior to the earlier of (a)&#160;an event of default (as defined in the Minosa Note) or (b)&#160;a date, which may be no earlier than December&#160;31, 2017, that is at least 60 days subsequent to written notice that MINOSA intends to demand payment. MINOSA has not provided any notice they intend to issue a payment demand notice. We unconditionally and irrevocably guaranteed all of the obligations under the Minosa Purchase Agreement and the Minosa Note. MINOSA has the right to convert all amounts outstanding under the Minosa Note into shares of our common stock upon 75 days&#8217; notice to us or upon a merger, consolidation, third party tender offer, or similar transaction relating to us at the conversion price of&#160;$4.41 per share.

As of December&#160;31, 2017, all of the BCF has been accreted to the income statement. The BCF represented a debt discount that was amortized over the life of the loan.

Since then, Epsilon has assigned $2.0&#160;million of the indebtedness under the Epsilon Note to MINOSA. Along with Epsilon, we entered into a second amended and restated convertible promissory note (the &#8220;Second AR Epsilon Note&#8221;), which further amends and restates the Epsilon Note. The stated principal amount of the Second AR Epsilon Note is $1.0&#160;million (which reflects the outstanding principal balance remaining after giving effect to Epsilon&#8217;s (x)&#160;previous assignment of $2.0&#160;million of the indebtedness under the Epsilon Note to MINOSA and (y)&#160;conversion of $3.0&#160;million of the indebtedness under the Epsilon Note into shares of our common stock).

However, the reduction in the conversion price resulted in a change in the fair value of the embedded conversion option that was more than 10% of the carrying value of the Note immediately prior to the modification. Because the amendment resulted in a substantial modification, extinguishment accounting was required, and we recorded a loss on the extinguishment of debt of $290,024. The extinguishment accounting resulted in a fair value reacquisition price of this debt of $1,340,024. The premium of $290,024 was being amortized over the remaining life of the debt.

Unless otherwise converted as described below, the entire outstanding amount of all Loans was originally due and payable on June&#160;6, 2020. As described in additional detail below, the maturity date was subsequently extended to November&#160;6, 2020, and on December&#160;8, 2020, the Company waived the maturity date extension causing the maturity date to revert back to June&#160;6, 2020 (the &#8220;Maturity Date&#8221;). </div></div><div style="text-indent: 9%; font-family: times new roman; font-size: 10pt; margin-top: 12pt; margin-bottom: 0pt;">At any time and from time to time until the three-month anniversary of the Maturity Date, all or any portion of the outstanding amount of each Note may, at the Investor&#8217;s election, be converted into shares of our common stock, par value $0.0001 per share (&#8220;Conversion Shares&#8221;). The number of Conversion Shares to be issued upon any conversion shall be equal to the quotient obtained by dividing the Applicable Conversion Amount (as defined below)&#160;by the Applicable Conversion Rate (as defined below). As defined in the Purchase Agreement, the &#8220;Applicable Conversion Amount&#8221; means, on the date of determination and with respect to each Note, (a)&#160;for the period beginning on the date of issuance and ending on the day immediately preceding the Maturity Date, an amount equal to 100.0% of the amount of the Loan evidenced by such Note then outstanding; (b)&#160;on the Maturity Date, 136.0% of the amount of the Loan evidenced by such Note then outstanding (such amount, the &#8220;Enhanced Conversion Amount&#8221;); (c)&#160;for the period beginning on the day immediately following the Maturity Date and for a period of three months thereafter (such three-month period, the &#8220;Accrual Period&#8221;), an amount equal to (i)&#160;the Enhanced Conversion Amount then outstanding plus (ii)&#160;an additional amount equal to 3.0% per month (prorated for any period of less than a full month) accrued on the amount described in clause (i); and (d)&#160;on any date after the Accrual Period, the amount then outstanding after giving effect to the accrual described in clause (c)&#160;during the Accrual Period (it being understood that no additional amount shall accrue after the expiration of the Accrual Period); and &#8220;Applicable Conversion Rate&#8221; means (x)&#160;with respect to any conversion on or prior to the Maturity Date, $5.00, and (y)&#160;with respect to any conversion after the Maturity Date, the lower of (i) $5.00 and (ii) 80.0% of <div style="white-space: nowrap; letter-spacing: 0px; top: 0px;;display:inline;">the&#160;ten-day&#160;volume-weighted</div> average price of Odyssey&#8217;s common stock. Notwithstanding anything in the Purchase Agreement to the contrary, we are prohibited from issuing any Conversion Shares, to the extent such shares, after giving effect to such issuance after conversion and when added to the number of Conversion Shares previously issued upon conversion of any of the Notes sold pursuant to the Purchase Agreement, would represent in excess of 19.9% of (A)&#160;the number of shares of our common stock outstanding immediately after giving effect to such issuances or (B)&#160;the total voting power of our securities outstanding immediately after giving effect to such issuances that are entitled to vote on a matter being voted on by holders of our common stock. <div style="font-size: 1px; letter-spacing: 0px; top: 0px;;display:inline;">&#160;</div></div><div style="text-indent: 9%; font-family: &quot;times new roman&quot;; font-size: 10pt; margin-top: 12pt; margin-bottom: 0pt; line-height: 12pt;">On May&#160;6, 2020, Odyssey and the Investor agreed to amend the Purchase Agreement to additionally provide that, notwithstanding anything in the Purchase Agreement to the contrary, Odyssey is prohibited from issuing any Conversion Shares, to the extent such shares, after giving effect to such issuance after conversion and when added to the number of Conversion Shares previously issued upon conversion of any of the Notes sold pursuant to the Purchase Agreement, would represent in excess of 19.9% of the number of shares of Common Stock outstanding as of December&#160;6, 2019. Due to a reference to the effective date of the amendment in the definition of the maturity date, the maturity date of the Note was inadvertently revised from June&#160;6, 2020 to November&#160;6, 2020. Thus, on December&#160;8, 2020 the Company amended the Notes to adjust the maturity date back to the original date of June&#160;6, 2020 and to extend the option to convert to December&#160;31, 2020. The modifications were evaluated under FASB ASC Topic <div style="white-space: nowrap; letter-spacing: 0px; top: 0px;;display:inline;"><div style="white-space: nowrap; letter-spacing: 0px; top: 0px;;display:inline;">470-50-40,</div></div> &#8220;Debt Modification and Extinguishments&#8221; but the instruments were determined not to be substantially different and extinguishment accounting did not apply. </div><div style="text-indent: 9%; font-family: times new roman; font-size: 10pt; margin-top: 12pt; margin-bottom: 0pt;"><div style="font-family: &quot;times new roman&quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;">During the year ended December&#160;31, 2020, the Investor converted the entire loan balance into 329,498 shares of our common stock at conversion rates ranging from $3.71 to $5.00 per share. </div></div><div style="text-indent: 9%; font-family: times new roman; font-size: 10pt; margin-top: 12pt; margin-bottom: 0pt;"><div style="font-family: &quot;times new roman&quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;">If, at any time prior to the Maturity Date, (a)&#160;we receive cash proceeds (the &#8220;Shipwreck Proceeds&#8221;) arising out of our salvage agreement relating to cargo recovered from a specified shipwreck, and (ii)&#160;the amount of the Shipwreck Proceeds equals at least 155.0% of the then-unpaid amount of all Loans, then we must repay in full the indebtedness outstanding under all the Notes by delivery of an amount equal to 155.0% of the then-unpaid amount of all Loans. In addition, at any time prior to the Maturity Date, we may repay all (but not less than all) of the then-unpaid amount of all Loans by delivery of an amount equal to 155.0% of the then-unpaid amount of all Loans; provided, that we must provide the Investor at least ten days&#8217; notice of our intention to repay the indebtedness. </div></div><div style="text-indent: 9%; font-family: times new roman; font-size: 10pt; margin-top: 12pt; margin-bottom: 0pt;"><div style="font-family: &quot;times new roman&quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;">The Purchase Agreement and the Notes issued by Odyssey on December&#160;10, 2019 and January&#160;29, 2020, include representations and warranties and other covenants, conditions, and other provisions customary for comparable transactions. </div></div><div style="text-indent: 9%; font-family: times new roman; font-size: 10pt; margin-top: 12pt; margin-bottom: 0pt;">We evaluated the Notes in accordance with ASC Topic 815, Derivatives and Hedging, and determined that they contain certain embedded derivatives whose economic risks and characteristics were not clearly and closely related to the risks of the host contract. The material embedded derivative features consisted of the embedded conversion option and contingent redemption provisions. We elected to initially and subsequently measure the Notes in their entirety at fair value, with changes in fair value recognized in earnings. FASB <div style="white-space: nowrap; letter-spacing: 0px; top: 0px;;display:inline;"><div style="white-space: nowrap; letter-spacing: 0px; top: 0px;;display:inline;">ASC&#160;825-10-25&#160;allows</div></div> us to elect the fair value option for recording financial instruments when they are initially recognized or if there is an event that <div style="white-space: nowrap; letter-spacing: 0px; top: 0px;;display:inline;">requires&#160;re-measurement&#160;of</div> the instruments at fair value, such as a significant modification of the debt. </div><div style="text-indent: 9%; font-family: times new roman; font-size: 10pt; margin-top: 12pt; margin-bottom: 0pt;"><div style="font-family: &quot;times new roman&quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;">Because the Notes are carried in their entirety at fair value, the value of the compound embedded conversion feature is embodied in that fair value. The Company estimates the fair value of the hybrid instrument based on a probability weighted analysis which considers the present value of the cash flows using a credit risk adjusted rate enhanced by the redemption feature and the value of the conversion option valued using a Monte Carlo model. This method was considered by management to be the most appropriate method of encompassing the credit risk and exercise behavior that a market participant would consider when valuing the hybrid financial instrument. </div></div><div style="text-indent: 9%; font-family: times new roman; font-size: 10pt; margin-top: 12pt; margin-bottom: 0pt;">Inputs used to value the hybrid instrument during the year ended December&#160;31, 2020 included, (i)&#160;present value of future cash flows using a credit risk adjusted rate ranging from <div style="white-space: nowrap; letter-spacing: 0px; top: 0px;;display:inline;">18%-24%</div> due solely to changes in benchmark interest rates, (ii)&#160;remaining term to maturity, (iii)&#160;volatility ranging from <div style="white-space: nowrap; letter-spacing: 0px; top: 0px;;display:inline;">35%-87%,</div> (iv) closing stock price on the valuation date, and (v)&#160;the conversion price based on the lesser of $5.00 or 80% of the <div style="white-space: nowrap; letter-spacing: 0px; top: 0px;;display:inline;">10-day</div> VWAP.

During the year ended December&#160;31, 2020, we received additional proceeds of $490,000, recorded a change in the fair value of the hybrid instrument of $732,958 and fully converted the Notes into 329,498 shares of our Common Stock. </div></div><div style="font-family: times new roman; font-size: 10pt; margin-top: 18pt; margin-bottom: 0pt;"><div style="font-family: &quot;times new roman&quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;"><div style="font-weight:bold;display:inline;">Note 11 &#8211; Payroll protection program </div></div></div><div style="text-indent: 9%; font-family: times new roman; font-size: 10pt; margin-top: 6pt; margin-bottom: 0pt;"><div style="font-family: &quot;times new roman&quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;">We applied to Fifth Third Bancorp (&#8220;Fifth Third&#8221;) under the Small Business Administration (the &#8220;SBA&#8221;) Paycheck Protection Program of the Coronavirus Aid, Relief and Economic Security Act of 2020 (the &#8220;CARES Act&#8221;) for a loan of $370,400 (the &#8220;Loan&#8221;), and the Loan was made on April&#160;16, 2020.

Monthly principal and interest payments, less the amount of any potential forgiveness (discussed below), will commence seven months from the month this Note is dated. We did not provide any collateral or guarantees for the Loan, nor did we pay any facility charge to obtain the Loan. The Promissory Note provides for customary events of default, including, among others, those relating to failure to make payment, bankruptcy, breaches of representations and material adverse effects. Odyssey may prepay the principal of the Loan at any time without incurring any prepayment charges. For the twelve months ended December&#160;31, 2020 and 2019, we recorded interest expense in the amount of $936 and $0, respectively. </div><div style="text-indent: 9%; font-family: times new roman; font-size: 10pt; margin-top: 12pt; margin-bottom: 0pt;">The Loan may be forgiven partially or fully if the Loan proceeds are used for covered payroll costs, rent and utilities, provided that such amounts are incurred during the eight-week period that commenced on April&#160;16, 2020, and at least 75% of any forgiven amount has been used for covered payroll costs. During June 2020, the 75% requirement was reduced to 60% and the eight-week period was amended to a <div style="white-space: nowrap; letter-spacing: 0px; top: 0px;;display:inline;">24-week</div> period.

The principal amount of the EIDL Loan is $149,900, with proceeds to be used for working capital purposes. Interest on the&#160;EIDL Loan accrues at the rate of 3.75% per annum and installment payments, including principal and interest of $731, are due monthly beginning twelve months from the date of the&#160;EIDL Loan.

Compensation and incentives at December&#160;31, 2020 includes $0.8&#160;million accrued incentive awards for the company employees at December&#160;31, 2019 and prior and $0.3&#160;million additional for 2020. The Board of Directors will only approve incentives to be paid when and if there is sufficient excess cash above and beyond normal operating requirements. Other operating at December&#160;31, 2020 contains general expense items resulting from general operations. The primary expense in Other operating $0.9&#160;million is for accrued exploration permits. Accrued interest is due to several lenders per debt agreements described in NOTE H. During the quarter ended September&#160;30, 2019, we received an earnest money deposit of $450,000 from a company controlled by Greg Stemm, our past Chairman of the Board (see NOTE J for further information). The earnest money deposit relates to a draft agreement related to potential sale of a stake of our equity in CIC. This transaction has not yet been consummated. Accrued insurance obligations for the years ended December&#160;31, 2020 and 2019 primarily consisted of directors and officers insurance obligations. </div></div><table border="0" style="width:100%; table-layout:fixed;" cellspacing="0" cellpadding="0"><tr><td></td></tr></table><span></span>

Each $50,000 &#8220;unit&#8221; entitled the holder to 1% of the gross revenue generated by the now named &#8220;<div style="font-style:italic;display:inline;;font-style:italic;display:inline;">Seattle</div>&#8221; project (formerly referred to as the &#8220;<div style="font-style:italic;display:inline;;font-style:italic;display:inline;">Republic</div>&#8221; project), and 100,000 shares of Common Stock. Gross revenue is defined as all cash proceeds payable to us as a result of the &#8220;<div style="font-style:italic;display:inline;;font-style:italic;display:inline;">Seattle</div>&#8221; project, excluding funds received by us to finance the project. </div></div><div style="text-indent: 9%; font-family: times new roman; font-size: 10pt; margin-top: 12pt; margin-bottom: 0pt;"><div style="font-family: &quot;times new roman&quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;">The participating rights balance will be amortized under the units of revenue method once management can reasonably estimate potential revenue for each of these projects.

If the project is successful and generates sufficient proceeds, Galt will recoup their investment plus three times the investment. Galt&#8217;s investment return will be paid out of project proceeds. Galt will receive 50% of project proceeds until this amount is recouped. Thereafter, they will share in additional net proceeds of the project at the rate of 1% for every million invested. Subsequent to the original syndication deal, we reached an agreement permitting Galt to bifurcate their selection between two projects, the SS <div style="font-style:italic;display:inline;;font-style:italic;display:inline;">Gairsoppa</div> and HMS <div style="font-style:italic;display:inline;;font-style:italic;display:inline;">Victory</div> with the residual 1% on additional net proceeds assigned to the HMS <div style="font-style:italic;display:inline;;font-style:italic;display:inline;">Victory</div> project only. The bifurcation resulted in $3,756,250 being allocated to each of the two projects. Therefore, Galt will receive 7.5125% of net proceeds from the HMS <div style="font-style:italic;display:inline;;font-style:italic;display:inline;">Victory</div> project after they recoup their investment of $3,756,250 plus three times the investment. Galt has been paid in full for their share of the <div style="font-style:italic;display:inline;;font-style:italic;display:inline;">Gairsoppa </div>project investment. There are no future payments remaining due to Galt for the <div style="font-style:italic;display:inline;;font-style:italic;display:inline;">Gairsoppa</div> project. Based on the timing of the proceeds earmarked for Galt, the relative corresponding amount of Galt&#8217;s revenue participation right of $3,756,250 was amortized into revenue in 2012 based upon the percent of Galt-related proceeds from the sale of silver as a percentage of total proceeds that Galt earned under the revenue participation agreement ($15.0 million). There is no expiration date on the Galt deal for the HMS <div style="font-style:italic;display:inline;;font-style:italic;display:inline;">Victory</div> project. If the archaeological excavation of the shipwreck is performed and insufficient proceeds are obtained, then the deferred income balance will be recognized as other income. If the archaeological excavation of the shipwreck is performed and sufficient proceeds are obtained, then the deferred income balance will be recognized as revenue. </div></div><table border="0" style="width:100%; table-layout:fixed;" cellspacing="0" cellpadding="0"><tr><td></td></tr></table><span></span>

The conversion price in effect from time to time is also subject to downward adjustment if we issue or sell shares of common stock for a purchase price less than the conversion price or if we issue or sell shares convertible into or exercisable for shares of common stock with a conversion price or exercise price less than the conversion price for the Series AA Preferred.</div></div><div style="color: rgb(0, 0, 0); font-family: 'times new roman'; font-style: normal; font-variant-ligatures: normal; font-variant-caps: normal; font-weight: 400; letter-spacing: normal; orphans: 2; text-align: start; text-indent: 0px; text-transform: none; white-space: normal; widows: 2; word-spacing: 0px; -webkit-text-stroke-width: 0px; text-decoration-thickness: initial; text-decoration-style: initial; text-decoration-color: initial; margin-top: 18pt; margin-bottom: 0pt; font-size: 10pt;"><div style="font-family: &quot;times new roman&quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;"><div style="font-weight:bold;display:inline;"><div style="font-style:italic;display:inline;;font-style:italic;display:inline;">Accounting considerations</div></div></div></div><div style="color: rgb(0, 0, 0); font-family: 'times new roman'; font-style: normal; font-variant-ligatures: normal; font-variant-caps: normal; font-weight: 400; letter-spacing: normal; orphans: 2; text-align: start; text-transform: none; white-space: normal; widows: 2; word-spacing: 0px; -webkit-text-stroke-width: 0px; text-decoration-thickness: initial; text-decoration-style: initial; text-decoration-color: initial; margin-top: 6pt; margin-bottom: 0pt; text-indent: 4%; font-size: 10pt;"><div style="font-family: &quot;times new roman&quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;">As stated above the issuance of the Series AA Convertible Preferred Stock is based on certain contingencies.

However, in order to perform this analysis, we were first required to evaluate the economic risks and characteristics of the Series AA Convertible Preferred Stock in its entirety as being either akin to equity or akin to debt. Our evaluation concluded that the Series AA Convertible Preferred Stock was more akin to an equity-like contract largely due to the fact that most of its features were participatory in nature. As a result, we concluded that the embedded conversion feature is clearly and closely related to the host equity contract and will not require bifurcation and liability classification.</div></div><div style="color: rgb(0, 0, 0); font-family: 'times new roman'; font-style: normal; font-variant-ligatures: normal; font-variant-caps: normal; font-weight: 400; letter-spacing: normal; orphans: 2; text-align: start; text-transform: none; white-space: normal; widows: 2; word-spacing: 0px; -webkit-text-stroke-width: 0px; text-decoration-thickness: initial; text-decoration-style: initial; text-decoration-color: initial; margin-top: 12pt; margin-bottom: 0pt; text-indent: 4%; font-size: 10pt;">The option to purchase the Series<div style="letter-spacing: 0px; top: 0px;;display:inline;">&#160;</div><div style="white-space: nowrap; letter-spacing: 0px; top: 0px;;display:inline;">AA-2</div><div style="letter-spacing: 0px; top: 0px;;display:inline;">&#160;</div>Convertible Preferred Stock was analyzed as a freestanding financial instrument and has terms and features of derivative financial instruments.

The plan expires on the tenth anniversary of the effective date. The Plan provides for the grant of incentive stock options,<div style="letter-spacing: 0px; top: 0px;;display:inline;">&#160;</div><div style="white-space: nowrap; letter-spacing: 0px; top: 0px;;display:inline;">non-qualified</div><div style="letter-spacing: 0px; top: 0px;;display:inline;">&#160;</div>stock options, restricted stock awards, restricted stock units and stock appreciation rights. This plan was initially capitalized with 450,000 shares that may be granted. The Plan is intended to comply with Section&#160;162(m) of the Internal Revenue Code, which stipulates that the maximum aggregate number of Shares with respect to one or more Awards that may be granted to any one person during any calendar year shall be 83,333, and the maximum aggregate amount of cash that may be paid in cash to any person during any calendar year with respect to one or more Awards payable in cash shall be $2,000,000. The original maximum number of shares that were to be used for Incentive Stock Options (&#8220;ISO&#8221;) under the Plan was 450,000. During our June 2016 stockholders meeting, the stockholders approved the addition of 200,000 incremental shares to the Plan. With respect to each grant of an ISO to a participant who is not a ten percent stockholder, the exercise price shall not be less than the fair market value of a share on the date the ISO is granted. With respect to each grant of an ISO to a participant who is a ten percent stockholder, the exercise price shall not be less than one hundred ten percent (110%) of the fair market value of a share on the date the ISO is granted. If an award is a<div style="letter-spacing: 0px; top: 0px;;display:inline;">&#160;</div><div style="white-space: nowrap; letter-spacing: 0px; top: 0px;;display:inline;">non-qualified</div><div style="letter-spacing: 0px; top: 0px;;display:inline;">&#160;</div>stock option (&#8220;NQSO&#8221;), the exercise price for each share shall be no less than (1)&#160;the minimum price required by applicable state law, or (2)&#160;the fair market value of a share on the date the NQSO is granted, whichever price is greatest. Any award intended to meet the performance based exception must be granted with an exercise price not less than the fair market value of a share determined as of the date of such grant.</div><div style="color: rgb(0, 0, 0); font-family: 'times new roman'; font-style: normal; font-variant-ligatures: normal; font-variant-caps: normal; font-weight: 400; letter-spacing: normal; orphans: 2; text-align: start; text-transform: none; white-space: normal; widows: 2; word-spacing: 0px; -webkit-text-stroke-width: 0px; text-decoration-thickness: initial; text-decoration-style: initial; text-decoration-color: initial; margin-top: 0pt; margin-bottom: 0pt; text-indent: 9%; font-size: 10pt;">&#160;</div><div style="color: rgb(0, 0, 0); font-family: 'times new roman'; font-style: normal; font-variant-ligatures: normal; font-variant-caps: normal; font-weight: 400; letter-spacing: normal; orphans: 2; text-align: start; text-transform: none; white-space: normal; widows: 2; word-spacing: 0px; -webkit-text-stroke-width: 0px; text-decoration-thickness: initial; text-decoration-style: initial; text-decoration-color: initial; margin-top: 0pt; margin-bottom: 0pt; text-indent: 9%; font-size: 10pt;">On March&#160;26, 2019, our Board of Directors adopted and approved the 2019 Stock Incentive Plan (the &#8220;2019 Plan&#8221;), which was approved by our stockholders on June&#160;3, 2019. The 2019 Plan expires on June&#160;3, 2029. The 2019 Plan provides for the grant of incentive stock options,<div style="letter-spacing: 0px; top: 0px;;display:inline;">&#160;</div><div style="white-space: nowrap; letter-spacing: 0px; top: 0px;;display:inline;">non-qualified</div><div style="letter-spacing: 0px; top: 0px;;display:inline;">&#160;</div>stock options, restricted stock awards, restricted stock units and stock appreciation rights. The 2019 Plan is capitalized with 800,000 shares that may be granted. No awards were made from the Plan prior to the effective date. The 2019 Plan includes the following features: no &#8220;evergreen&#8221; share reserve, prohibits liberal share recycling, no repricing permitted without stockholder approval, no stock option reload features, no transfers of awards for value and dividends and dividends equivalent shall accrue and be paid only if and to the extent the common stock underlying the award become vested or payable.</div><div style="color: rgb(0, 0, 0); font-family: 'times new roman'; font-style: normal; font-variant-ligatures: normal; font-variant-caps: normal; font-weight: 400; letter-spacing: normal; orphans: 2; text-align: start; text-transform: none; white-space: normal; widows: 2; word-spacing: 0px; -webkit-text-stroke-width: 0px; text-decoration-thickness: initial; text-decoration-style: initial; text-decoration-color: initial; margin-top: 12pt; margin-bottom: 0pt; text-indent: 9%; font-size: 10pt;"><div style="font-family: &quot;times new roman&quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;">Share-based compensation expense recognized during the period is based on the value of the portion of share-based payment awards that is ultimately expected to vest. As share-based compensation expense recognized in the statement of operations is based on awards ultimately expected to vest, it can be reduced for estimated forfeitures. The ASC topic Stock Compensation requires forfeitures to be estimated at the time of grant and revised, if necessary, in subsequent periods if actual forfeitures differ from those estimates. The share-based compensation charged against income for the periods ended December&#160;31, 2020, 2019 and 2018 was $420,648, $756,596 and $415,615, respectively. The 2019 amount includes $675,000 of equity-based compensation issued from a subsidiary for director fees.</div></div><div style="color: rgb(0, 0, 0); font-family: 'times new roman'; font-style: normal; font-variant-ligatures: normal; font-variant-caps: normal; font-weight: 400; letter-spacing: normal; orphans: 2; text-align: start; text-transform: none; white-space: normal; widows: 2; word-spacing: 0px; -webkit-text-stroke-width: 0px; text-decoration-thickness: initial; text-decoration-style: initial; text-decoration-color: initial; margin-top: 12pt; margin-bottom: 0pt; text-indent: 9%; font-size: 10pt;"><div style="font-family: &quot;times new roman&quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;">We did not grant stock options to employees or outside directors in 2020, 2019 or 2018. If options were granted, their values would be determined using the Black-Scholes-Merton option-pricing model, which values options based on the stock price at the grant date, the expected life of the option, the estimated volatility of the stock, the expected dividend payments, and the risk-free interest rate over the life of the option.</div></div><div style="color: rgb(0, 0, 0); font-family: 'times new roman'; font-style: normal; font-variant-ligatures: normal; font-variant-caps: normal; font-weight: 400; letter-spacing: normal; orphans: 2; text-align: start; text-transform: none; white-space: normal; widows: 2; word-spacing: 0px; -webkit-text-stroke-width: 0px; text-decoration-thickness: initial; text-decoration-style: initial; text-decoration-color: initial; margin-top: 12pt; margin-bottom: 0pt; text-indent: 9%; font-size: 10pt;"><div style="font-family: &quot;times new roman&quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;">The Black-Scholes-Merton option pricing model was developed for estimating the fair value of traded options that have no vesting restrictions and are fully transferable. Because option valuation models require the use of subjective assumptions, changes in these assumptions can materially affect the fair value of the options. Our options do not have the characteristics of traded options; therefore, the option valuation models do not necessarily provide a reliable measure of the fair value of our options.</div></div><div style="color: rgb(0, 0, 0);

Key Employee Cuota Appreciation Rights (the &#8220;Key Employee Plan&#8221;) and the Odyssey Marine Exploration, Inc. Nonemployee Director Cuota Appreciation Rights (the &#8220;Director Plan&#8221; and, together with the Key Employee Plan, the &#8220;Cuota Plans&#8221;). The Cuota Plans provide for the award of cuota appreciation rights (&#8220;CARs&#8221;) to eligible participants. A &#8220;cuota&#8221; is a unit of equity interest under Panamanian law, and the value of the CARs will be determined based upon the appreciation, if any, in the value of the cuotas of Oceanica Resources, S. de R.L., a Panamanian sociedad de responsabilidad limitada (&#8220;Oceanica&#8221;), after the award of such CARs. The Company indirectly holds a majority stake in Oceanica.</div></div><div style="color: rgb(0, 0, 0); font-family: 'times new roman'; font-style: normal; font-variant-ligatures: normal; font-variant-caps: normal; font-weight: 400; letter-spacing: normal; orphans: 2; text-align: start; text-transform: none; white-space: normal; widows: 2; word-spacing: 0px; -webkit-text-stroke-width: 0px; text-decoration-thickness: initial; text-decoration-style: initial; text-decoration-color: initial; margin-top: 12pt; margin-bottom: 0pt; text-indent: 9%; font-size: 10pt;"><div style="font-family: &quot;times new roman&quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;">The Board authorized the award of up to 750,000 CARs under the Key Employee Plan and the award of up to 600,000 CARs under the Director Plan. The terms of any CARs awarded under the Cuota Plans will be set forth in an award agreement between the Company and each participant, and the award agreement will set forth a vesting schedule for the CARs. In general, unvested CARs will be forfeited upon a participant&#8217;s separation of service from the Company, and all vested and unvested CARs will be forfeited upon a participant&#8217;s separation of service from the Company for &#8220;cause&#8221; (as defined in the Cuota Plans).</div></div><div style="color: rgb(0, 0, 0); font-family: 'times new roman'; font-style: normal; font-variant-ligatures: normal; font-variant-caps: normal; font-weight: 400; letter-spacing: normal; orphans: 2; text-align: start; text-transform: none; white-space: normal; widows: 2; word-spacing: 0px; -webkit-text-stroke-width: 0px; text-decoration-thickness: initial; text-decoration-style: initial; text-decoration-color: initial; margin-top: 12pt; margin-bottom: 0pt; text-indent: 9%; font-size: 10pt;"><div style="font-family: &quot;times new roman&quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;">Each participant in the Cuota Plans will be entitled to be paid the value of such participant&#8217;s CARs upon the occurrence of a &#8220;payment event.&#8221; As used in the Cuota Plans, payment events consist of a change in control of the Company or the date specified in the applicable award agreement and, in the case of the Key Employee Plan, a separation of service without cause and the participant&#8217;s continuous employment with the Company until the date specified in the applicable award agreement. The value of CARs liability will be based upon the difference between the basis in the cuotas of Oceanica on the date of the award of the CARs, which is $3.00, and the fair value of the cuotas on the date used for the payment event, in each case as determined by the Board in accordance with the provisions of the Cuota Plans. The fair value of the cuota as of August&#160;31, 2019 was $1.00. There is no active market for Oceanica&#8217;s securities, and there was no activity that would have materially changed the valuation at December&#160;31, 2020.</div></div><div style="color: rgb(0, 0, 0);

As required by the Accounting for Income Taxes topic in the ASC, we have evaluated whether it is more likely than not that the deferred tax assets will be realized. Based on the available evidence, we have concluded that it is more likely than not that those assets would not be realized without the recovery and rights of ownership or salvage rights of high-value shipwrecks or other forms of taxable income, thus a valuation allowance has been recorded as of December&#160;31, 2020. </div></div><div style="text-indent: 9%;

This equity would only be issuable upon the Mexican&#8217;s government approval and issuance of the Environmental Impact Assessment (&#8220;EIA&#8221;) for our Mexican subsidiary. All possible grants of new equity shares were approved by the Administrators of Oceanica. We also owe consultants contingent success fees of up to $700,000 upon the approval and issuance of the EIA.

Our ability to generate net income or positive cash flows for the following twelve months is dependent upon financings, our success in developing and monetizing our interests in mineral exploration entities, generating income from exploration charters, collecting on amounts owed to us, and completing the MINOSA/Penelope equity financing transaction approved by our stockholders on June&#160;9, 2015. </div></div><div style="text-indent: 9%; font-family: times new roman; font-size: 10pt; margin-top: 12pt; margin-bottom: 0pt;"><div style="font-family: &quot;times new roman&quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;">Our 2020 business plan required us to generate new cash inflows to effectively allow us to perform our planned projects. We continually plan to generate new cash inflows through the monetization of our receivables and equity stakes in seabed mineral companies, financings, syndications or other partnership opportunities. If cash inflow ever becomes insufficient to meet our desired projected business plan requirements, we would be required to follow a contingency business plan which is based on curtailed expenses and fewer cash requirements. On August&#160;21, 2020, we sold an aggregate of 2,553,314 shares of our common stock and warrants to purchase up to 1,901,989 shares of our common stock. The net proceeds received from this sale, after offering expenses of $0.3&#160;million, of which $0.2&#160;million was withheld to cover fees, were $11.3&#160;million (See NOTE L). These proceeds, coupled with the anticipated cash inflows, were expected to provide operating funds through early 2022. </div></div><div style="text-indent: 9%; font-family: times new roman; font-size: 10pt; margin-top: 12pt; margin-bottom: 0pt;"><div style="font-family: &quot;times new roman&quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;">On March&#160;11, 2015, we entered into a Stock Purchase Agreement with Minera del Norte S.A. de c.v. (&#8220;MINOSA&#8221;) and Penelope Mining LLC (&#8220;Penelope&#8221;), an affiliate of MINOSA, pursuant to which (a)&#160;MINOSA agreed to extend short-term, debt financing to Odyssey of up to $14.75&#160;million, and (b)&#160;Penelope agreed to invest up to $101&#160;million over three years in convertible preferred stock of Odyssey. The equity financing is subject to the satisfaction of certain conditions, including the approval of our stockholders which occurred on June&#160;9, 2015, and MINOSA and Penelope are currently under no obligation to make the preferred share equity investments. </div></div><div style="text-indent: 9%; font-family: times new roman; font-size: 10pt; margin-top: 12pt; margin-bottom: 0pt;">Our consolidated <div style="white-space: nowrap; letter-spacing: 0px; top: 0px;;display:inline;">non-restricted</div> cash balance at December&#160;31, 2020 was $6.2&#160;million. We have a working capital deficit at December&#160;31, 2020 of $47.0&#160;million. Our largest loan of $14.75&#160;million from MINOSA had a due date of December&#160;31, 2017 which is now linked to other stipulations, see NOTE H for further detail. The majority of our remaining assets have been pledged to MINOSA, and its affiliates, and to Monaco Financial LLC, leaving us with few opportunities to raise additional funds from our balance sheet. The total consolidated book value of our assets was approximately $11.8&#160;million at December&#160;31, 2020, which includes cash of $6.2&#160;million, and the fair market value of these assets may differ from their net carrying book value. Even though we executed the above noted financing arrangement with Penelope, Penelope must purchase the shares for us to be able to complete the equity component of the transaction. The Penelope equity transaction is heavily dependent on the outcome of our subsidiary&#8217;s application approval process for an environmental permit (EIA) to commercially develop a mineralized phosphate deposit off the coast of Mexico. The factors noted above raise doubt about our ability to continue as a going concern. These consolidated financial statements do not include any adjustments to the amounts and classification of assets and liabilities that may be necessary should we be unable to continue as a going concern. </div><div style="font-family: times new roman; font-size: 10pt; margin-top: 18pt; margin-bottom: 0pt;"><div style="font-family: &quot;times new roman&quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;"><div style="font-weight:bold;display:inline;">Lease commitment </div></div></div><div style="text-indent: 9%; font-family: times new roman; font-size: 10pt; margin-top: 6pt; margin-bottom: 0pt;">In August 2019, we entered into an operating lease for our corporate office space under a <div style="white-space: nowrap; letter-spacing: 0px; top: 0px;;display:inline;">non-cancellable</div> lease through August 2024 with monthly payments ranging from $11,789 to $13,269, not including sales tax. The lease provides for annual increases of base rent of 3% until the expiration date. Pursuant to ASC 842, an operating lease right of usage (ROU) asset and liability were recognized in the amount of $590,612 at inception of the lease based on the present value of lease payments over the remaining lease term. The ROU asset represents the Company&#8217;s right to use the underlying office space asset for the lease term, and the lease liability represents the Company&#8217;s obligation to make lease payments arising from the lease. Since the implicit rate of interest in the arrangement was not readily determinable, we utilized our incremental borrowing rate of 10% in determining the present value of lease payments. The operating lease ROU asset includes any lease payments made and excludes lease incentives. </div><div style="text-indent: 9%; font-family: times new roman; font-size: 10pt; margin-top: 12pt; margin-bottom: 0pt;"><div style="font-family: &quot;times new roman&quot;;

This trade payable bears a simple annual interest rate of 12%. As collateral, they were granted a primary lien on certain items of our marine equipment. The carrying value of this equipment is zero. This agreement matured in August of 2018. During the three-months ended June&#160;30, 2018, we sold various marine equipment to Magellan for $1.0&#160;million and the assumption of this vendor&#8217;s trade payable and accrued interest, however, we remain as guarantor on this trade payable. We recorded a gain of approximately $0.9&#160;million from the cash proceeds alone. Included in this equipment is the equipment noted above the vendor has a primary lien on. The vendor has consented to Magellan&#8217;s assumption of this debt but did not release us from our obligations. If Magellan defaults and the vendor forecloses on this equipment currently in possession of Magellan, we then have a contingent liability to Magellan in the amount of $0.5&#160;million for two of the key assets<br/>. </div></div><table border="0" style="width:100%; table-layout:fixed;" cellspacing="0" cellpadding="0"><tr><td></td></tr></table><span></span>

For all other entities, the amendments are effective for fiscal years beginning after December&#160;15, 2023, including interim periods within those fiscal years. Early adoption is permitted, but no earlier than fiscal years beginning after December&#160;15, 2020, including interim periods within those fiscal years. The Board specified that an entity should adopt the guidance as of the beginning of its annual fiscal year. </div><div style="text-indent: 9%; font-family: times new roman; font-size: 10pt; margin-top: 12pt; margin-bottom: 0pt;"><div style="font-family: &quot;times new roman&quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;">The amendments in the above Update affect entities that issue convertible instruments and/or contracts in an entity&#8217;s own equity. For convertible instruments, the instruments primarily affected are those issued with beneficial conversion features or cash conversion features because the accounting models for those specific features are removed. However, all entities that issue convertible instruments are affected by the amendments to the disclosure requirements in this Update. For contracts in an entity&#8217;s own equity, the contracts primarily affected are freestanding instruments and embedded features that are accounted for as derivatives under the current guidance because of failure to meet the settlement conditions of the derivatives scope exception related to certain requirements of the settlement assessment. The Board simplified the settlement assessment by removing the requirements (1)&#160;to consider whether the contract would be settled in registered shares, (2)&#160;to consider whether collateral is required to be posted, and (3)&#160;to assess shareholder rights. Those amendments also affect the assessment of whether an embedded conversion feature in a convertible instrument qualifies for the derivatives scope exception. Additionally, the amendments in this Update affect the diluted EPS calculation for instruments that may be settled in cash or shares and for convertible instruments.

This method requires that any financial statement impact from adoption be recognized as a cumulative adjustment to retained earnings as of the date of adoption. The adoption of this ASU did not change the timing of the Company&#8217;s revenue recognition for any contracts and, therefore, the adoption of this standard did not have a material impact on the Company&#8217;s financial statements. </div><div style="text-indent: 9%; font-family: times new roman; font-size: 10pt; margin-top: 12pt; margin-bottom: 0pt;"><div style="font-family: &quot;times new roman&quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;">Revenue is recognized when a customer obtains control of promised goods or services, in an amount that reflects the consideration which the Company expects to receive in exchange for those goods or services. To determine revenue recognition for arrangements that the Company determines are within the scope of ASC Topic 606, the Company performs the following five steps: (i)&#160;identify the contract(s) with a customer; (ii)&#160;identify the performance obligations in the contract; (iii)&#160;determine the transaction price; (iv)&#160;allocate the transaction price to the performance obligations in the contract; and (v)&#160;recognize revenue when (or as) the Company satisfies a performance obligation. The Company only applies the five-step model to contracts when it is probable that the Company will collect the consideration it is entitled to in exchange for the goods or services it transfers to the customer. At contract inception, once the contract is determined to be within the scope of ASC Topic 606, the Company assesses the goods or services promised within each contract and determines those that are performance obligations and assesses whether each promised good or service is distinct. The Company then recognizes as revenue the amount of the transaction price that is allocated to the respective performance obligation when (or as) the performance obligation is satisfied. Sales, value add, and other taxes collected on behalf of third parties are excluded from revenue. </div></div><div style="text-indent: 9%; font-family: times new roman; font-size: 10pt; margin-top: 12pt; margin-bottom: 0pt;"><div style="font-family: &quot;times new roman&quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;">The Company currently generates revenues from four customers with contracts. There are two sources of revenue, marine services, and other services. The contracts for both services provide research, scientific services, marine operations planning, management execution, and project management. These services are billed generally on a monthly basis and recognized as revenue as the services are performed. Revenue is recognized at a point in time as services are provided, as the customers simultaneously receive and consume the benefits provided by the Company each month. The Company generally does not receive any upfront consideration for these services, and there is no variable consideration for the services.&#160;Costs associated with both services include all direct consulting labor, and minimal supplies, and is charged to operations as a component of Operations and Research. </div></div><div style="text-indent: 9%; font-family: times new roman; font-size: 10pt; margin-top: 12pt; margin-bottom: 0pt;"><div style="font-family: &quot;times new roman&quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;">Accounts receivable are based on amounts billed to customers. Generally accepted accounting principles state an estimate is to be made for an allowance for doubtful accounts. We have determined no allowance is currently necessary.

Decisions are based on several factors, including, but not limited to, management&#8217;s plans for future operations, recent operating results and projected cash flows. Impairment losses are included in depreciation at the time of impairment.

Depreciation is calculated using the straight-line method at rates based on the assets&#8217; estimated useful lives which are normally between three and thirty years. Leasehold improvements are amortized over their estimated useful lives or lease term, if shorter. Items that may require major overhauls (such as engines or generators) that enhance or extend the useful life of vessel related assets qualify to be capitalized and depreciated over the useful life or remaining life of that asset, whichever was shorter. Certain major repair items required by industry standards to ensure a vessel&#8217;s seaworthiness also qualified to be capitalized and depreciated over the period of time until the next scheduled planned major maintenance for that item. All other repairs and maintenance were accounted for under the direct-expensing method and are expensed when incurred. </div></div><table border="0" style="width:100%; table-layout:fixed;" cellspacing="0" cellpadding="0"><tr><td></td></tr></table><span></span>

<td class="text"><div style="font-family: times new roman; font-size: 10pt; margin-top: 18pt; margin-bottom: 0pt;"><div style="font-family: &quot;times new roman&quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;"><div style="font-weight:bold;display:inline;">Earnings Per Share </div></div></div><div style="text-indent: 9%; font-family: times new roman; font-size: 10pt; margin-top: 6pt; margin-bottom: 0pt;">Basic earnings per share (&#8220;EPS&#8221;) is computed by dividing income available to common stockholders by the weighted-average number of common shares outstanding for the period. In periods when the Company has income, the Company would calculate basic earnings per share using the <div style="white-space: nowrap; letter-spacing: 0px; top: 0px;;display:inline;">two-class</div> method, if required, pursuant to ASC 260 <div style="font-style:italic;display:inline;;font-style:italic;display:inline;">Earnings Per Share.</div> The <div style="white-space: nowrap; letter-spacing: 0px; top: 0px;;display:inline;">two-class</div> method was required effective with the issuance of certain senior convertible notes in the past because these notes qualified as a participating security, giving the holder the right to receive dividends should dividends be declared on common stock. Under the <div style="white-space: nowrap; letter-spacing: 0px; top: 0px;;display:inline;">two-class</div> method, earnings for a period are allocated on a pro rata basis to the common stockholders and to the holders of convertible notes based on the weighted average number of common shares outstanding and number of shares that could be issued upon conversion. The Company does not use the <div style="white-space: nowrap; letter-spacing: 0px; top: 0px;;display:inline;">two-class</div> method in periods when it generates a loss because the holder of the convertible notes does not participate in losses. Currently, we do not have any outstanding convertible notes that qualify as a participating security. </div><div style="text-indent: 9%; font-family: times new roman; font-size: 10pt; margin-top: 12pt; margin-bottom: 0pt;">Diluted EPS reflects the potential dilution that would occur if dilutive securities and other contracts to issue common stock were exercised or converted into common stock or resulted in the issuance of common stock that then shared in our earnings. We use the treasury stock method to compute potential common shares from stock options and warrants and the <div style="white-space: nowrap; letter-spacing: 0px; top: 0px;;display:inline;">if-converted</div> method to compute potential common shares from preferred stock, convertible notes or other convertible securities. For diluted earnings per share, the Company uses the more dilutive of the <div style="white-space: nowrap; letter-spacing: 0px; top: 0px;;display:inline;">if-converted</div> method or <div style="white-space: nowrap; letter-spacing: 0px; top: 0px;;display:inline;">two-class</div> method. When a net loss occurs, potential common shares have an anti-dilutive effect on earnings per share and such shares are excluded from the diluted EPS calculation. </div><div style="text-indent: 9%; font-family: times new roman; font-size: 10pt; margin-top: 12pt; margin-bottom: 0pt;"><div style="font-family: &quot;times new roman&quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;">At December&#160;31, 2020, 2019 and 2018 the weighted average common shares outstanding were 10,538,114, 9,346,213 and 8,583,795, respectively. For the periods ending December&#160;31, 2020, 2019 and 2018 in which net losses occurred, all potential common shares were excluded from Diluted EPS because the effect of including such shares would be anti-dilutive. </div></div><div style="text-indent: 9%;

Further, derivative financial instruments are initially, and subsequently, measured at fair value and recorded as liabilities or, in rare instances, assets. We generally do not use derivative financial instruments to hedge exposures to cash-flow, market or foreign-currency risks. However, we have entered into certain other financial instruments and contracts with features that are either (i)&#160;not afforded equity classification, (ii)&#160;embody risks not clearly and closely related to host contracts, or (iii)&#160;may be <div style="white-space: nowrap; letter-spacing: 0px; top: 0px;;display:inline;">net-cash</div> settled by the counterparty. As required by ASC 815 &#8211; <div style="font-style:italic;display:inline;;font-style:italic;display:inline;">Derivatives and Hedging</div>, these instruments are required to be carried as derivative liabilities, at fair value, in our financial statements with changes in fair value reflected in our income. </div><div style="text-indent: 9%; font-family: times new roman; font-size: 10pt; margin-top: 12pt; margin-bottom: 0pt;"><div style="font-family: &quot;times new roman&quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;">We adopted ASC Topic 820 for certain financial instruments measured as fair value on a recurring basis. ASC Topic 820 defines fair value, established a framework for measuring fair value in accordance with accounting principles generally accepted in the United States and expands disclosures about fair value measurements. Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. ASC Topic 820 established a three-tier fair value hierarchy which prioritizes the inputs used in measuring fair value. </div></div><div style="text-indent: 9%; font-family: times new roman; font-size: 10pt; margin-top: 12pt; margin-bottom: 0pt;"><div style="font-family: &quot;times new roman&quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;">The hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (level 1 measurements) and the lowest priority to unobservable inputs (level 3 measurements).

Warrants and rights outstanding are derivative securities that give the holder the right to purchase securities (usually equity) from the issuer at a specific price within a certain time frame. Warrants are often included in a new debt issue to entice investors by a higher return potential. The main difference between warrants and call options is that warrants are issued and guaranteed by the company, whereas options are exchange instruments and are not issued by the company. Also, the lifetime of a warrant is often measured in years, while the lifetime of a typical option is measured in months. Disclose the title of issue of securities called for by warrants and rights outstanding, the aggregate amount of securities called for by warrants and rights outstanding, the date from which the warrants or rights are exercisable, and the price at which the warrant or right is exercisable.</p></div>

<td class="text">During the period ended March 31, 2018, Monaco advanced us $1.0 million that was applied to a loan agreement that was executed on April 20, 2018. Monaco also agreed to treat $99,366 of back rent owed by us to Monaco as part of this loan resulting in an aggregate principal amount of $1,099,367 at December 31, 2020 and 2019. The indebtedness bears interest at 10.0% percent per year. During January 2020 this loan agreement was amended by increasing the interest rate to 18%. All principal and any unpaid interest is to be payable on the first anniversary of this agreement, April 20, 2019. This debt is secured by cash proceeds, if any, from our future shipwreck projects we have contracted with Magellan. As additional consideration, their share purchase option expiration date, as discussed in Note 1 &#8211; Monaco 2014 and Note 2 &#8211; Monaco 2016 above, has been extended from 30 days to seven months after the note becomes paid in full.
