ODYSSEY MARINE EXPLORATION, INC. AND SUBSIDIARIES

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS

NOTE A – BASIS OF PRESENTATION

The accompanying unaudited consolidated financial statements of Odyssey Marine Exploration, Inc. and subsidiaries (the “Company,” “Odyssey,” “us,” “we” or “our”) have been prepared in accordance with the rules and regulations of the Securities and Exchange Commission and the instructions to Form 10-Q and, therefore, do not include all information and footnotes normally included in financial statements prepared in accordance with generally accepted accounting principles. These interim consolidated financial statements should be read in conjunction with the consolidated financial statements and notes included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2013.

In the opinion of management, these financial statements reflect all adjustments, including normal recurring adjustments, necessary for a fair presentation of the financial position as of March 31, 2014, and the results of operations and cash flows for the interim periods presented. Operating results for the three-month period ended March 31, 2014, are not necessarily indicative of the results that may be expected for the full year.

NOTE B – SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

This summary of significant accounting policies of the Company is presented to assist in understanding our financial statements. The financial statements and notes are representations of the Company’s management, who are responsible for their integrity and objectivity, and have prepared them in accordance with our customary accounting practices.

Principles of Consolidation

The consolidated financial statements include the accounts of the Company and its direct and indirect wholly owned subsidiaries, Odyssey Marine Services, Inc., OVH, Inc., Odyssey Retriever, Inc., Odyssey Marine Entertainment, Inc., Odyssey Marine Enterprises, Ltd., Odyssey Marine Management, Ltd., Oceanica Marine Operations, S.R.L., and majority interests in Oceanica Resources, S.R.L. and Exploraciones Oceanicas, S. De R.L. De C.V. 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 non-controlling interest are presented within equity and net income, and are shown separately from the Company’s equity and net income attributable to the Company.

Use of Estimates

Management used estimates and assumptions in preparing these financial statements in accordance with generally accepted accounting principles. 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.

Revenue Recognition and Accounts Receivable

In accordance with Topic A.1. in SAB 13: Revenue Recognition, exhibit and expedition charter revenue is recognized ratably when realized and earned as time passes throughout the contract period as defined by the terms of the agreement. Expenses related to the exhibit and expedition charter revenue are recorded as incurred and presented under the caption “Operations and research” on our Consolidated Statements of Income.

Artifact sales and other may also consist of revenues related to the recovery of bulk silver bullion from the Gairsoppa project that exceeds the directly related operating and recovery expenses. Revenue is recognized when our contractual obligation is completed to deliver the silver bullion to the refining agent, the amount of revenue is reasonably assured based on the London Bullion Market rates and the bullion is in a format ready for sale into the market. 2014 revenue does not contain Gaisoppa project silver sales. Operating and recovery expenses incurred in connection with the Gairsoppa contract consist of vessel-related expenses (ships’ crew, provisions, port fees and charter expenses), fuel, specialized equipment and administrative expenses. These expenses are charged to the Consolidated Statements of Income as incurred and subsequently reimbursed per our contract and recorded as a benefit (credit to expense) in the period we are assured of recoupment.

Artifact sales and other is where we would recognize deferred revenue related to revenue participation rights we previously sold to investors. Upon receipt of funds payable to the investors for their revenue participation rights, revenue would be recognized based upon the percent of investor-related proceeds from the sale of silver as a percentage of total proceeds that investor could earn under the revenue participation agreement.

6

Under our agreement with the United Kingdom Government for the Gairsoppa project, any proceeds from the recovery of the government-owned silver cargo were first applied as a reimbursement to us for search and recovery expenses related to the project. Any remaining net proceeds from the silver owned by the United Kingdom Government were then split 20/80 between the government and us, respectively. In 2013 the proceeds from the silver sales were sufficient to fully reimburse our expenses and to provide net proceeds that were split between the two parties. The Gairsoppa project revenue recognized by us in 2013 resulted from our share of the net proceeds from the sale of the recovered silver bullion that belonged to the United Kingdom Government. The United Kingdom Government reimburses us for all of the expenses incurred by us to recover their silver. Accordingly, we applied the expense reimbursement credit against our search and recovery expenses in our respective years Consolidated Statement of Income under the caption “Operating Expenses: Operations and Research.”

Bad debts are recorded as identified and, from time to time, a specific reserve allowance will be established when required. A return allowance is established for sales that have a right of return. Accounts receivable is stated net of any recorded allowances.

Cash, Cash Equivalents and Restricted Cash

Cash, 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.

Inventory

Our inventory consists of artifacts recovered from the SS Gairsopa and SS Republic shipwrecks, general branded merchandise and related packaging material. Inventoried costs of recovered artifacts include the costs of recovery, conservation and administrative costs to obtain legal title to the artifacts. Administrative costs are generally legal fees or insurance settlements required in order to obtain clear title. The capitalized recovery costs include direct costs such as vessel and related equipment operations and maintenance, crew and technical labor, fuel, provisions, supplies, port fees and depreciation. Conservation costs include fees paid to conservators for cleaning and preserving the artifacts. We continually monitor the recorded aggregate costs of the artifacts in inventory to ensure these costs do not exceed the net realizable value. Historical sales, publications or available public market data are used to assess market value.

Packaging materials and merchandise are recorded at average cost. We record our inventory at the lower of cost or market.

Costs associated with the above noted items are the costs included in our costs of goods. Vessel costs associated with expedition revenue as well as exhibit costs are not included in cost of goods sold. Vessel costs include, but are not limited to, charter costs, fuel, crew and port fees. Vessel and exhibit costs are included in Operations and research in the Consolidated Statements of Operations. In the case of prior revenues associated with the Gairsoppa project, the United Kingdom owned the silver we sold into the London Bullion Market on their behalf, therefore, there was no associated cost of goods.

Long-Lived Assets

Our policy is to recognize impairment losses relating to long-lived assets in accordance with the ASC topic for Property, Plant and Equipment. Decisions are based on several factors, including, but not limited to, management’s plans for future operations, recent operating results and projected cash flows.

Comprehensive Income

Securities with a maturity greater than three months from purchase date are deemed available-for-sale and carried at fair value. Unrealized gains and losses on these securities are excluded from earnings and reported as a separate component of stockholders’ equity. At March 31, 2014, we did not own securities with a maturity greater than three months.

Property and Equipment and Depreciation

Property and equipment is stated at historical cost. Depreciation is provided using the straight-line method at rates based on the assets’ estimated useful lives, which are normally between three and ten years. Leasehold improvements are amortized over their estimated useful lives or lease term, if shorter. Major overhaul items (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 is shorter. Certain major repair items required by industry standards to ensure a vessel’s seaworthiness also qualify 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 are accounted for under the direct-expensing method and are expensed when incurred.

Earnings Per Share

Basic earnings per share (“EPS”) 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 generates income, the Company calculates basic earnings per share using the two-class method pursuant to ASC 260 Earnings Per Share. The two-class method was required effective with the issuance of the Senior Convertible Note disclosed in Note I because the note qualifies as a participating security, giving the holder the right to receive dividends should dividends be declared on common stock. Under the two-class method, earnings for the 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 converted. The Company does not use the two-class method in periods when it generates a loss as the holder of the Convertible Notes do not participate in losses.

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 if-converted method to compute potential common shares from Preferred Stock, Convertible Notes or other convertible securities. As it relates solely to the Senior Convertible Note, for diluted earnings per share, the Company uses the more dilutive of the if-converted method or two-class 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.

At March 31, 2014 and 2013, weighted average common shares outstanding year-to-date were 83,937,883 and 77,344,388, respectively. For the periods ended March 31, 2014 and 2013, 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.

The potential common shares in the following tables represent potential common shares calculated using the treasury stock method from outstanding options, stock awards and warrants that were excluded from the calculation of diluted EPS:

Income Taxes

Income taxes are accounted for using an asset and liability approach that requires the recognition of deferred tax assets and liabilities for the expected future tax consequences attributable to differences between financial statement carrying amounts of existing assets and liabilities and their respective tax bases. A valuation allowance is provided when it is more likely than not that some portion or the entire deferred tax asset will not be realized.

Stock-based Compensation

Our stock-based compensation is recorded in accordance with the guidance in the ASC topic for Stock-Based Compensation (See NOTE J).

Fair Value of Financial Instruments

Financial instruments consist of cash, evidence of ownership in an entity, and contracts that both (i) impose on one entity a contractual obligation to deliver cash or another financial instrument to a second entity, or to exchange other financial

9

instruments on potentially unfavorable terms with the second entity, and (ii) conveys to that second entity a contractual right (a) to receive cash or another financial instrument from the first entity, or (b) 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, mortgage and loans payable, and redeemable preferred stock, if any. 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. If any, we carry redeemable preferred stock at historical cost and accrete carrying values to estimated redemption values over the term of the financial instrument.

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 (See NOTE M for additional information). We generally do not use derivative financial instruments to hedge exposures to cash-flow, market or foreign-currency risks. However, in the past, we have entered into certain other financial instruments and contracts, such as the sale and issuance of redeemable preferred stock and freestanding warrants with features that are either (i) not afforded equity classification, (ii) embody risks not clearly and closely related to host contracts, or (iii) may be net-cash settled by the counterparty. As required by ASC 815 – Derivatives and Hedging, 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.

Fair Value Hierarchy

The three levels of inputs that may be used to measure fair value are as follows:

Level 1. Quoted prices in active markets for identical assets or liabilities.

Level 2. Observable inputs other than Level 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 2 inputs also include non-binding market consensus prices that can be corroborated with observable market data, as well as quoted prices that were adjusted for security-specific restrictions.

Level 3. Unobservable inputs to the valuation methodology are significant to the measurement of the fair value of assets or liabilities. Level 3 inputs also include non-binding market consensus prices or non-binding broker quotes that we were unable to corroborate with observable market data.

Redeemable Preferred Stock

If we issue redeemable preferred stock instruments (and, if ever, any other redeemable financial instrument we may enter into) they are initially evaluated for possible classification as a liability in instances where redemption is certain to occur pursuant to ASC 480 – Distinguishing Liabilities from Equity. Redeemable preferred stock classified as a liability is recorded and carried at fair value. Redeemable preferred stock that does not, in its entirety, require liability classification is evaluated for embedded features that may require bifurcation and separate classification as derivative liabilities. In all instances, the classification of the redeemable preferred stock host contract that does not require liability classification is evaluated for equity classification or mezzanine classification based upon the nature of the redemption features. Generally, mandatory redemption requirements or any feature that could require cash redemption for matters not within our control, irrespective of probability of the event occurring, requires classification outside of stockholders’ equity. Redeemable preferred stock that is recorded in the mezzanine section is accreted to its redemption value through charges to stockholders’ equity when redemption is probable using the effective interest method.

Subsequent Events

We have evaluated subsequent events for recognition or disclosure through the date this Form 10-Q is filed with the Securities and Exchange Commission.

NOTE C – RESTRICTED CASH

As required by the original mortgage loan entered into with Fifth Third Bank (the “Bank”) on July 11, 2008, $500,000 was deposited into an interest-bearing account from which principal and interest payments are made. This mortgage loan has since been extended to July 2016. As extended, the new loan calls for a restricted cash balance of $400,000 to be funded annually for principal and interest payments (see NOTE I). The balance in the restricted cash account is held as additional collateral by the Bank and is not available for operations. The balance in this account at March 31, 2014, was $361,205.

NOTE F – INVESTMENTS IN UNCONSOLIDATED ENTITIES

Neptune Minerals, Inc.

During the quarter ended December 31, 2009, we invested $500,000 for a 25% interest (five membership units) in SMM Project, LLC (“SMM”) to pursue opportunities in the exploration of deep-ocean gold and copper deposits. SMM purchased a majority interest in Bluewater Metals Pty, Ltd. (“Bluewater”), an Australian company with licenses for mineral exploration of approximately 150,000 square kilometers of ocean floor in territorial waters controlled by four different countries in the South Pacific. In April 2010, SMM was acquired by Dorado Ocean Resources, Ltd. (“DOR”) through a share exchange. At that time, DOR also acquired the remaining interest in Bluewater. We were issued 450 DOR shares in exchange for our surrendered units in SMM. We also acquired an additional 1,200 shares of DOR valued at $2,000,000 that resulted in a 41.25% ownership of DOR. Under the terms of the Share Subscription Agreement, we had the option to pay for this investment in cash, provide marine services to DOR over a three-year period commencing April 2010, or exercise our contractual right to offset against the $2,000,000 marine services accounts receivable owed to us. During 2011, we exercised our contractual right and offset these two amounts. The focus of DOR was on the exploration and monetization of gold- and copper-rich Seafloor Massive Sulfide (“SMS”) deposits.

During 2011, we were engaged by Neptune Minerals, Inc. (“NMI”) and its affiliates to perform marine services relating to deep-sea mining. The agreements provided for payments in cash and shares of Class B non-voting common stock of NMI. In 2011, we earned 2,066,600 shares of the Class B non-voting common stock from these engagements. During this same period, NMI completed a share exchange with DOR shareholders whereby each one outstanding share of DOR was exchanged for 1,000 shares of NMI Class B non-voting common stock. We received 1,650,000 shares of NMI Class B non-voting common stock for our 1,650 DOR shares pursuant to the share exchange. In connection with this share exchange, NMI executed an assignment and assumption agreement, whereby NMI assumed $8,227,675 of the outstanding debt DOR owed to us. Additionally in 2011, we executed a debt conversion agreement with NMI, whereby we converted $2,500,000 of the debt owed to us for 2,500,000 shares of NMI Class B non-voting common stock. We have a net share position in NMI of 6,184,976 Class B non-voting shares, which currently represents an approximate 29.6% ownership interest.

11

Regarding the debt conversion noted in the preceding paragraph, NMI’s shares were valued at $1.00 based on their most recent capital raise at the time when we executed the debt conversion agreement. Pursuant to that agreement, we converted $2,500,000 of the debt owed to us for 2,500,000 shares of NMI Class B non-voting common stock. All the $8,227,675 receivable was fully reserved for in 2010. Thus the $2,500,000 portion of the debt owed to us had a book basis of zero. When we received the 2,500,000 shares as settlement of this accounts receivable, we took the position that the shares received had a carryover basis of zero until we could convert the shares to cash. Accordingly, no gain or loss was recognized in our financial statements in connection with this transaction.

At March 31, 2014, our share of unrecognized DOR (NMI) losses is $19.7 million. We have not recognized the accumulated $19.7 million in our income statement because these losses exceed our investment in DOR (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. Based on the NMI and DOR transactions described above, we believe it is appropriate to allocate this loss carryforward of $19.7 million to any incremental NMI investment that may be recognized on our balance sheet in excess of zero. The aforementioned loss carryforward is based on NMI’s last unaudited financial statements as of March 31, 2014. We do not have any guaranteed obligations to NMI, nor are we otherwise committed to provide financial support. Even though we were not obligated, during the three-months ended September 30, 2013, we, along with a second creditor, loaned funds to NMI of which our share is $500,000, and this indebtedness is evidenced by a convertible note. This funding was not for the purpose of funding NMI’s prior losses but for current requirements. Per ASC 323-10-35-29: Additional Investment After Suspension of Loss Recognition, we concluded this loan does not increase our ownership nor is it to be considered in-substance stock. Based on the financial position of NMI at December 31, 2013, we reserved for this note in its entirety. This note carried an interest rate of 6% per annum and matured on April 26, 2014. The note contained a mandatory conversion clause if the note remained unpaid at maturity. The note was convertible into NMI’s Class A voting shares at $12.00 per share upon maturity. During April 2014, we modified the conversion feature with NMI whereas, during April 2014, the note was converted into 55,225 shares of Class A Preferred non-voting stock. These shares are convertible into 522,500 shares of Class A voting shares.

Chatham Rock Phosphate, Ltd.

During the period ended June 30, 2012, we performed deep-sea mining exploratory services for Chatham Rock Phosphate, Ltd. (“CRP”) valued at $1,680,000. As payment for these services, CRP issued 9,320,348 of ordinary shares to us. The shares currently represent a 6.5% equity stake in CRP. With CRP being a thinly traded stock on the New Zealand Stock Exchange and guidance per ASC 320: Debt and Equity Securities regarding readily determinable fair value, we believe it was appropriate to not recognize this amount as an asset nor as revenue during that period.

NOTE G – INCOME TAXES

For the quarter ended March 31, 2014, we generated $8.4 million of federal NOL carryforwards and $1.2 million of foreign NOL carryforwards. As of March 31, 2014, the Company had consolidated income tax net operating loss (“NOL”) carryforwards for federal tax purposes of approximately $116.9 million and net operating loss carryforwards for foreign income tax purposes of approximately $10.7 million. The federal NOL carryforwards from 1998 forward will expire in various years beginning in 2018 and ending through the year 2032.

Deferred income tax assets and liabilities are recognized for the estimated future tax consequences attributable to differences between financial statement carrying amounts of existing assets and liabilities and their respective tax bases. Deferred income tax assets and liabilities are measured using enacted tax rates expected to be recovered or settled. We have recorded a net deferred tax asset of $0 at March 31, 2014. As required by the Accounting for Income Taxes topic in the ASC, we have concluded it is more likely than not that those assets would not be realizable without the recovery and rights of ownership or salvage rights of high value shipwrecks or substantial profits from our mining operations and thus a valuation allowance has been recorded as of March 31, 2014. There was no U.S. income tax expense for the three months ended March 31, 2014 due to the generation of net operating losses which were not previously benefited in the Company’s financial statements.

The increase in the valuation allowance as of March 31, 2014 is due to the generation of $9.6 million in net operating loss carryforwards.

The change in the valuation allowance is as follows:

March 31, 2014	$	54,955,172
December 31, 2013		51,625,159
Change in valuation allowance	$	3,330,013

12

Our estimated annual effective tax rate for first quarter of 2014 is 34.39% while our effective tax rate is 0% because of the full valuation allowance. We have not recognized a material adjustment in the liability for unrecognized tax benefits and have not recorded any provisions for accrued interest and penalties related to uncertain tax positions.

The earliest tax year still subject to examination by a major taxing jurisdiction is 2010.

We are currently in the process of seeking a private letter ruling request with the Internal Revenue Service which will grant us relief to make a late election to carryback our 2008 federal NOL either three, four, or five taxable years preceding the taxable year of the applicable NOL, in lieu of the general two-year carryback period. We would carryback the NOL five years to the 2003 tax year. There would be no cash-tax benefit of the carryback as we had a taxable loss during the 2003 tax year. The benefit of making the 5 year carryback election is that the 2008 NOL will now be able to offset 100 percent of future alternative minimum taxable income instead of only offsetting 90 percent. If the Internal Revenue Service grants us relief we will reverse the prior AMT tax liability in the quarter relief is granted as we will be able to fully offset alternative minimum taxable income instead of only 90 percent.

NOTE H – COMMITMENTS AND CONTINGENCIES

Legal Proceedings

The Company may be subject to a variety of other claims and suits that arise from time to time in the ordinary course of business. We are currently not a party to any pending litigation.

Trends and Uncertainties

Our 2014 business plan requires us to generate new cash inflows during 2014 to effectively allow us to perform our planned projects. We plan to generate new cash inflows through the monetization of shipwreck cargo or our equity stakes in seabed mineral companies, financings, syndications or other partnership opportunities. One or more of the planned shipwreck or mining project monetizations, financings, syndications or partnership opportunities may not be realized which may require us to curtail our desired business plan until we generate additional cash. We can offer no assurance any of our planned projects will be successful in providing additional cash during 2014. We have experienced several years of net losses. Our capacity to generate net income in future periods is dependent upon our success in recovering and monetizing shipwrecks, monetizing our interests in mineral exploration entities, generating income from shipwreck or mineral exploration charters or generating income from other projects. In 2014, we will seek to monetize some of our stake in our mineral exploration shareholdings, recover and monetize cargo from the SS Central America, and generate cash inflows from other projects and opportunities. If cash inflow is not sufficient to meet our desired projected business plan requirements, we will be required to follow our contingency business plan which is based on curtailed expenses and requires less new cash inflows. While we have been successful in generating cash inflows and raising the necessary funds in the past, there can be no assurance that we can continue to do so in 2014.

NOTE I – MORTGAGE AND LOANS PAYABLE

The Company’s consolidated debt consisted of the following at March 31, 2014 and December 31, 2013:

	March 31, 2014		December 31, 2013
Term loan	$	4,500,000	$	5,000,000
Project loan		—		10,000,000
Face value $10,000,000, 8% Convertible Senior Note Payable		—		1,176,076
Face value $8,000,000, 9% Convertible Senior Note Payable		2,341,646		4,039,446
Mortgage payable		1,777,924		1,816,286
	$	8,619,570	$	22,031,808

Term Loan

Our current term loan, which is a result of amending its predecessor during July 2013, has a maturity date in July 2016. This facility bears floating interest at the one month LIBOR rate as reported in the Wall Street Journal plus 500 basis points. Beginning January 2014, we were required to make semi-annual payments of $500,000. Any prepayments made in full or in part were without premium or penalty. No restricted cash payments are required to be kept on deposit. This facility has substantially all the same terms that were attached to its predecessors as disclosed in previous Securities and Exchange Commissions filings.

13

This term loan is secured by approximately 25,000 numismatic coins recovered from the SS Republic shipwreck, which amount will be reduced over the term by the amount of coins sold by the Company. The coins used as collateral are held by a custodian for the security of the Bank. The carrying value of the borrowing base is not to exceed forty percent (40%) of the eligible coin inventory valued on a rolling twelve-month wholesale average value. The Company is required to comply with a number of customary covenants. The significant covenants include: maintaining insurance on the inventory; ensuring the collateral is free from encumbrances and without the consent of the Bank, the Company cannot merge or consolidate with or into any other corporation or entity nor can the Company enter into a material debt agreement with a third party without approval. We were in compliance with all covenants at March 31, 2014.

Project Term Loan

During July 2013, we entered into a $10.0 million project term loan agreement with Fifth Third Bank. The facility was to mature on July 24, 2014 but was repaid in its entirety during March 2014. This term loan bore interest at a floating rate equal to the one-month LIBOR rate plus 500 basis points. We were able to make prepayments in whole or in part without premium or penalty. An origination fee of $50,000 was paid at closing. A restricted cash deposit of $500,000 was required to cover interest payments. The term loan was secured by $10.0 million that was monetized from approximately 1.8 million ounces of silver recovered from the SS Gairsoppa. We were required to comply with a number of customary affirmative and negative covenants of which we were in compliance during the existence of this facility. The proceeds were used to fund project recovery costs.

Mortgage Payable

On July 11, 2008, we entered into a mortgage loan with Fifth Third Bank. Pursuant to the Loan Agreement, we borrowed $2,580,000. The loan bore interest at a variable rate equal to the prime rate plus three-fourths of one percent (0.75%) per annum. The loan matured on July 11, 2013, and required monthly principal payments in the amount of $10,750 plus accrued interest. This loan was secured by a restricted cash balance as well as a first mortgage on our corporate office building. This loan contained customary representations and warranties, affirmative and negative covenants, conditions, and other provisions.

During July 2013 when the above noted mortgage matured, we extended it on substantially the same terms that previously existed. The new maturity date is July 2016. The loan bears interest at a variable rate equal to the prime rate plus three-fourths of one percent (0.75%) per annum. Monthly principal payments in the amount of $10,750 plus accrued interest are required. This loan is secured by a restricted cash balance (See NOTE C) as well as a first mortgage on our corporate office building. This loan contains customary representations and warranties, affirmative and negative covenants, conditions, and other provisions. As of March 31, 2014, the loan balance outstanding was $1,216,000.

During May 2008, we entered into a mortgage loan in the principal amount of $679,000 with The Bank of Tampa to purchase our conservation lab and storage facility. This obligation has a monthly payment of $5,080 with a maturity date of May 14, 2015. Principal and interest payments are payable monthly. Interest is at a fixed annual rate of 6.45%. This debt is secured by the related mortgaged real property. As of March 31, 2014, the loan balance outstanding was $561,923.

Senior Convertible Notes

Initial Note

During November 2011, we entered into a securities purchase agreement (the “Purchase Agreement”) with one institutional investor pursuant to which we issued and sold a Senior Convertible Note in the original principal amount of $10.0 million (the “Initial Note”) and a warrant (the “Warrant”) to purchase up to 1,302,083 shares of our common stock. Subject to the satisfaction of conditions set forth in the Purchase Agreement, we had the right to require the investor to purchase an additional senior convertible note in the original principal amount of up to $5.0 million on the six-month anniversary of the initial closing date (the “Additional Note” and, collectively “Notes”). Aggregate direct finance costs amounted to $545,000 of which $45,000 related to costs of the lender and, accordingly, were included in the original issue discount on the Initial Note.

The indebtedness evidenced by the Initial Note bears interest at 8.0% percent per year (15% under default conditions, if applicable). Interest is compounded monthly and payable quarterly at the beginning of each calendar quarter. The Initial Note is amortized with equal monthly principal installments of $434,783 that commenced on July 8, 2012. Prepayment is not allowed. Further, the Notes may be converted into our common stock, at the option of the holder, at any time following issuance, with respect to the Initial Note, or at any time following six months after the date of issuance, with respect to the Additional Note. The initial conversion price of the Initial Note was $3.74, subject to adjustment on the six-month anniversary of the initial closing date as follows: The reset conversion price applicable to the Initial Note was to be adjusted to the lesser of (a) the then current conversion price and (b) the greater of (i) $1.44 and (ii) 110.0% of the market price of our common stock on the six-month anniversary of the initial closing date (as applicable, the “Conversion Price”). On May 10, 2012 (the six-month anniversary of the initial closing date), the conversion price applicable to the Initial Note was adjusted to $3.17, which represented 110.0% of the market price of Odyssey’s common stock. The conversion price is also subject to adjustment for stock splits, stock dividends,

14

recapitalizations, and similar transactions. We agreed to pay each amortization payment in shares of our common stock, if certain conditions are met; provided, that we may, at our option, elect to pay such amortization payments in cash. The conversion rate applicable to any amortization payment that we make in shares of our common stock will be the lower of (a) the Conversion Price and (b) a price equal to 85.0% of the average for a ten-day period immediately prior to the applicable amortization date of the volume-weighted average price of our shares of common stock.

The Initial Note provides for redemption upon the occurrence of an event of default. Default conditions include non-servicing of the debt and certain other credit risk related conditions. Default conditions also include certain equity indexed events including failures to file public information documents, non-conversion or insufficient share authorizations to effect conversion and failure to obtain and maintain an effective registration statement covering the underlying common shares. The remedies to the investor for events of default include acceleration of payment at 125% of the remaining face value in certain circumstances. In the event the default redemption is not paid, the investor would have the right to elect conversion of the note at an adjusted conversion price approximating 75% of quoted market prices. A change in control would also result in a redemption requirement at 125% of the face value.

The Notes extend no voting rights to the investors. However, the Notes extend participation rights in dividend payments, if any, made to the holders of the Company’s common or other class of stock, except our Series G Preferred Stock.

The holder of the Initial Note elected to apply some of the payments due on the principal balance of the Initial Note to the Additional Note described below. During the year ended December 31, 2013, we issued 3,282,934 shares of common stock as payment of $8,608,694 in outstanding principal. During the three months ended March 31, 2014, the remaining principal balance of $1,391,306 was paid in full in cash.

Under the terms of the Warrant, the holder is entitled to exercise the Warrant to purchase up to 1,302,083 shares of our common stock at an initial exercise price of $4.32 per share, during the five-year period beginning on the six-month anniversary of the initial closing date; provided, that 434,027 shares of our common stock issuable upon exercise of the Warrant could not be exercised unless the investor purchased the Additional Note. In accordance with the terms of the warrant agreement, on May 10, 2012, the exercise price applicable to the Warrant was adjusted to $3.60 which was the lesser of (a) the then current exercise price and (b) 125.0% of the market price of our common stock on the six-month anniversary of the initial closing date. The Exercise Price is also subject to adjustment for stock splits, stock dividends, recapitalizations, and similar transactions. We are generally prohibited from issuing shares of common stock upon exercise of the Warrant if such exercise would cause us to breach our obligations under the rules or regulations of the stock market on which the common stock is traded.

In connection with the financing, we entered into a registration rights agreement pursuant to which we filed a registration statement with the Securities and Exchange Commission (with the “SEC”) relating to the offer and sale by the investor of the shares of common stock issuable upon conversion of the Notes and the exercise of the Warrant. Pursuant to the agreement, we were required to file the registration statement within six months of the initial closing date and to use best efforts for the registration statement to be declared effective 90 days thereafter (or 120 days thereafter if the registration statement is subject to review by the SEC).

Additional Note

On May 10, 2012, we issued the Additional Note in the original principal amount of $8.0 million, and the number of shares of Odyssey’s common stock issuable upon exercise of the Warrant increased to 1,562,500. The Additional Note bears interest at 9.0% per year and will mature on the 30-month anniversary of the initial closing date. The Additional Note amortizes in equal monthly installments commencing on the eighth-month anniversary of the initial note and may be paid in cash or Odyssey common stock. The Additional Note may be converted into Odyssey’s common stock, at the option of the holder, at any time following six months after the date of issuance. The conversion rate applicable to any amortization payment that we make in shares of our common stock will be the lower of (a) the Conversion Price and (b) a price equal to 85.0% of the average for a ten-day period immediately prior to the applicable amortization date of the volume-weighted average price of our shares of common stock. The initial conversion price of the Additional Note is $3.74, subject to reset on the earlier of the date the registration statement registering the offer and sale of the common stock issuable under the notes and the warrants becomes effective and a prospectus contained therein shall be available for the resale by the holder of all of the registrable securities or the six-month anniversary of the additional closing date. The registration statement was declared effective on July 6, 2012, and there was no reset to the conversion price of the Additional Note.

On January 2, 2013, we entered into an agreement to amend the terms of the Additional Note. The installment payments due December 1, 2012, January 1, 2013 and February 1, 2013 were deferred until March 1, 2013 and the conversion price on the Additional Note was decreased from $3.74 to $3.17. We evaluated the amendment’s impact on the accounting for the Additional Note in accordance with ASC 470-50-40-6 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% and the reduction in the conversion price resulted in a change in the fair value of the embedded conversion option that was less than 10% of the carrying value of the

15

Additional Note immediately prior to the modification. Since the amendment did not result in a substantial modification, extinguishment accounting was not applicable. During the three months ended March 31, 2014, the $1,739,130 of the principal balance was paid in cash. The principal balance of the Additional Note at March 31, 2014 was $2,347,826 which is bifurcated on our balance sheet between derivative liabilities and mortgage and loans payable.

Accounting considerations

We have accounted for the Initial Note, Additional Note and Warrant issued for cash as a financing transaction, wherein the net proceeds that we received were allocated to the financial instruments issued. Prior to making the accounting allocation, we evaluated the Initial Note, Additional Note and the Warrant for proper classification under ASC 480 Distinguishing Liabilities from Equity (“ASC 480”) and ASC 815 Derivatives and Hedging (“ASC 815”).

ASC 815 generally requires the analysis 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 material embedded derivative features consisted of the conversion option and related conversion reset price protection, the Company’s redemption privilege, and certain redemption rights that were indexed to equity risks. The conversion option and conversion reset price protection, along with the redemption features bearing risks of equity, were not clearly and closely related to the host debt agreement and required bifurcation. Current accounting principles that are also provided in ASC 815 do not permit an issuer to account separately for individual derivative terms and features that require bifurcation and liability classification. Rather, such terms and features must be and were bundled together and fair valued as a single, compound embedded derivative.

The Warrant has a term of five and one-half years and at inception, had an initial exercise price of $4.32. The contractual exercise price is subject to adjustment for both traditional recapitalization events and was reset on the sixth month anniversary of issuance to $3.60 per share. Although the warrant did not fall within the scope of ASC 480, the warrant required derivative liability accounting because the conversion price reset protection terms are not consistent with the definition for financial instruments indexed to a company’s own stock.

Based on the previous conclusions, we allocated the cash proceeds first to the derivative components at their fair values (see NOTE M) with the residual allocated to the host debt contract, as follows:

	Allocation
Initial Note	$	4,910,862
Compound embedded derivative		2,989,537
Derivative warrants		2,054,601
	$	9,955,000

The basis that was subject to allocation included the gross proceeds of $10,000,000, less costs of the investor paid out of proceeds that amounted to $45,000. We also allocated the direct financing costs of $500,000 to the note payable and the derivative components based upon the relative fair values of these financial instruments. As a result of this allocation, $246,653 was recorded in deferred costs and $253,347 was recorded as expense.

Allocation of the cash proceeds related to the Additional Financing was as follows:

	Allocation
Additional Note	$	6,339,642
Compound embedded derivative		1,291,298
Derivative warrants		363,542
	$	7,994,482

The basis that was subject to allocation included the gross proceeds of $8,000,000, less costs of the investor paid out of proceeds that amounted to $5,518. We also allocated the direct financing costs of $400,000 to the note payable and the derivative components based upon the relative fair values of these financial instruments. As a result of this allocation, $317,201 was recorded in deferred costs and $82,799 was recorded as expense.

The financing basis allocated to the notes payable and the deferred asset arising from direct finance costs are subject to amortization with periodic charges to interest expense using the effective interest method. Amortization of these components included in interest expense during the three months ended March 31, 2014 and 2013 amounted to $271,606 and $689,333, respectively. The derivative components are subject to re-measurement to fair value at the end of each reporting period with the change reflected in income. See NOTE M for information about our derivatives.

NOTE J – STOCKHOLDERS’ EQUITY

Common Stock

In 2013, we issued 3,552,357 shares of common stock, valued at $9,279,887, representing payment for principal and interest on our Initial Note and Additional Note as described in NOTE I

During the three-month period ended March 31, 2013, we issued 2,010,500 shares of common stock to accredited investors upon exercise of their outstanding warrants.

Warrants

We have 2,087,500 warrants outstanding. 1,562,500 warrants are attached to our Senior Convertible debt discussed further in NOTES I and M. The conversion price on these warrants is $3.60 and are set to expire on November 9, 2016. The remaining 525,000 warrants remain were attached to our former Series G Preferred stock. These warrents have a conversion price of $2.44 and expired on April 13, 2014. See NOTE M for further information on these warrants.

Stock-Based Compensation

We have one active stock incentive plan, the 2005 Stock Incentive Plan. The 1997 Stock Incentive Plan expired on August 17, 2007. As of that date, options could no longer be granted from that Plan but any granted and unexercised options continued to exist until exercised or they expired. As of December 31, 2013 all outstanding options in the 1997 Stock Incentive Plan have expired. The 2005 Stock Incentive Plan provides for the grant of incentive stock options, non-qualified stock options, restricted stock awards, restricted stock units and stock appreciation rights. We initially reserved 2,500,000 of our authorized but unissued shares of common stock for issuance under the Plan, and, at the time the Plan was adopted, not more than 500,000 of these shares could be used for restricted stock awards and restricted stock units. On January 16, 2008, the Board of Directors approved amendments to the Plan to add 2,500,000 shares of common stock to the Plan, to allow any number of shares to be used for restricted stock awards, to clarify certain other provisions in the Plan and to submit the amended Plan for stockholder approval. The amended Plan was approved at the annual meeting of stockholders on May 7, 2008. On June 3, 2010, our stockholders’ approved an amendment to the 2005 Stock Incentive Plan which resulted in the addition of 3,000,000 shares of common stock to the Plan. Any incentive option and non-qualified option granted under the Plan must provide for an exercise price of not less than the fair market value of the underlying shares on the date of grant, but the exercise price of any incentive option granted to an officer, director or eligible employee owning more than 10% of our outstanding common stock must not be less than 110% of fair market value on the date of the grant.

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 three-month periods ended March 31, 2014 and 2013 was $492,775 and $688,580.

The weighted average estimated fair value of stock options granted during the three-month periods ended March 31, 2014 and 2013 was $1.28 and $1.44, respectively. The weighted average fair value of stock options granted is determined using the Black-Scholes 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. The Black-Scholes option valuation 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 or variations from these assumptions can materially affect the fair value of the options. The assumptions used in the Black-Scholes model were as follows for stock options granted during the three-month periods ended:

	March 31, 2014	March 31, 2013
Risk-free interest rate	2.11 - 2.66%	.41 - .63%
Expected volatility of common stock	63.54 - 65.03%	64.04 - 68.26%
Dividend yield	0%	0%
Expected life of options	6.1 - 8.2 years	3.0 - 4.1 years

NOTE K – DEFERRED REVENUE

Since 2009, we entered into several marine search services contracts associated with the Robert Frasier Marine, Ltd. projects. For each contract, revenue is recognized over the contractual period when services are performed as defined by the contract. The period of time a search project remains active varies but usually extends over several months and may be accelerated or extended depending upon operational factors. At March 31, 2014, we have a $1,840,404 service obligation on one service contract that will be recognized as revenue over the period of time the contractual services are provided. At December 31, 2013, we had the same service obligation of $1,840,404.

NOTE L – CONCENTRATION OF CREDIT RISK

We maintain the majority of our cash at one financial institution. At March 31, 2014, our uninsured cash balance was approximately $6.0 million.

Our term loans bear a variable interest rate based on LIBOR and our primary mortgage bears interest at a variable rate based on the prime rate. See NOTE I for further detail on these instruments. These instruments expose us to interest rate risk. On our primary mortgage, for an increase of every 100 basis points, our interest obligation increases by approximately, on average, $906 per month until maturity in July 2016. An increase of 100 basis points to the interest rate on our term loans increases our interest obligation, at most, by approximately, on average, $2,800 per month. See NOTE I. If an increase to the rates on these instruments occurs, it will have an adverse effect on our operating cash flows and financial condition but we believe it would not be material.

NOTE M – DERIVATIVE FINANCIAL INSTRUMENTS

The following tables summarize the components of our derivative liabilities and linked common shares as of March 31, 2014 and December 31, 2013 and the amounts that were reflected in our income related to our derivatives for the years then ended:

Our Series G Convertible Preferred Stock and Warrant Financing Transaction on October 11, 2010, Series G Convertible Preferred Stock and Warrant Settlement Transaction during April 2011, and Senior Convertible Note and Warrant Financing

18

Transaction on November 8, 2011 gave rise to derivative financial instruments. We entered into a Series G Convertible Preferred Stock and Warrant Financing Transaction and the Series G Convertible Preferred Stock and Warrant Settlement Transaction on October 11, 2010 and April 14, 2011, respectively. These transaction have since expired. The Series G Convertible Preferred Stock embodied certain terms and features that both possessed all of the conditions of derivative financial instruments and were not clearly and closely related to the host preferred contract in terms of economic risks and characteristics. These terms and features consist of the embedded conversion option and the related down-round anti-dilution protection provision, the Company’s redemption privilege and the holder’s redemption privilege. Each of the redemption features also embodies the redemption premium payments. Warrants issued with this transaction and the subsequent Settlement Transaction embodied down-round anti-dilution protection and, accordingly, were not afforded equity classification.

As more fully discussed in NOTE I, we entered into the Senior Convertible Note and Warrant Financing Transactions on November 8, 2011 and May 10, 2012. The Senior Convertible Notes embodied certain terms and conditions that were not clearly and closely related to the host debt agreement in terms of economic risks and characteristics. These terms and features consist of the embedded conversion options, certain redemption features and a conversion price reset feature. Warrants issued with this transaction embodied reset price protection and, accordingly, were not afforded equity classification.

Current accounting principles that are provided in ASC 815 - Derivatives and Hedging require derivative financial instruments to be classified in liabilities and carried at fair value with changes recorded in income. In addition, the standards do not permit an issuer to account separately for individual derivative terms and features embedded in hybrid financial instruments that require bifurcation and liability classification as derivative financial instruments. Rather, such terms and features must be bundled together and fair valued as a single, compound embedded derivative. We have selected the Monte Carlo Simulations valuation technique to fair value the compound embedded derivative because we believe that this technique is reflective of all significant assumption types, and ranges of assumption inputs, that market participants would likely consider in transactions involving compound embedded derivatives. Such assumptions include, among other inputs, interest risk assumptions, credit risk assumptions and redemption behaviors in addition to traditional inputs for option models such as market trading volatility and risk free rates. We have selected Binomial Lattice to fair value our warrant derivatives because we believe this technique is reflective of all significant assumption types market participants would likely consider in transactions involving freestanding warrants derivatives. The Monte Carlo Simulations technique is a level three valuation technique because it requires the development of significant internal assumptions in addition to observable market indicators.

Significant inputs and results arising from the Monte Carlo Simulations process are as follows for the compound embedded derivative that has been bifurcated from our Senior Convertible Note and classified in liabilities:

	March 31, 2014	December 31, 2013
Quoted market price on valuation date	$2.29	$2.02
Contractual conversion rate	$3.17	$3.17
Range of effective contractual conversion rates	—	—
Contractual term to maturity	0.085 Years	0.33 Years
Implied expected term to maturity	0.085 Years	0.33 Years
Market volatility:
Range of volatilities	18.2% - 38.4%	47.4% - 91.2%
Range of equivalent volatilities	27.3%	59.9% - 69.9%
Contractual interest rate	9.0%	8.0 - 9.0%
Range of equivalent market risk adjusted interest rates	9.08%	8.08% - 9.08%
Range of equivalent credit risk adjusted yields	0.64%	0.67%
Risk-free rates	0.03% - 0.05%	0.01% - 0.07%

The following table reflects the issuances of compound embedded derivatives, redemptions and changes in fair value inputs and assumptions related to the compound embedded derivatives during the three months ended March 31, 2014 and 2013.

	For the three months ended March 31,

The fair value of the compound embedded derivative is significantly influenced by our trading market price, the price volatility in trading and the interest components of the Monte Carlo Simulation technique.

On October 11, 2010, we also issued warrants to acquire 1,800,000 of our common shares in connection with the Series G Convertible Preferred Stock Financing. During April 4-8, 2011, we issued warrants to acquire 525,000 of our common shares in connection the Series G Convertible Preferred Stock and Warrant Settlement Transaction. Finally, on November 8, 2011, we issued warrants to acquire 1,302,083 of our common shares in connection with the Senior Convertible Note Financing Transaction. These warrants required liability classification as derivative financial instruments because certain down-round anti-dilution protection or price protection features included in the warrant agreements are not consistent with the concept of equity. We applied the Binomial Lattice valuation technique in estimating the fair value of the warrants because we believe that this technique is most appropriate and reflects all of the assumptions that market participants would likely consider in transactions involving the warrants, including the potential incremental value associated with the down-round anti-dilution protections.

The Binomial Lattice technique is a level three valuation technique because it requires the development of significant internal assumptions in addition to observable market indicators. All remaining warrants linked to 1,725,000 shares of common stock were exercised on October 11, 2013. Therefore, the warrants linked to 1,725,000 shares of common stock were not outstanding as of March 31, 2014 and December 31, 2013. Significant assumptions and utilized in the Binomial Lattice process are as follows for the warrants as of March 31, 2014:

	March 31, 2013
Linked common shares	1,725,000
Quoted market price on valuation date	$3.26
Contractual exercise rate	$2.4648

Of the 1,302,083 common shares accessible from the warrant issued on November 8, 2011, 434,027 of those common shares were accessible only based upon the Company’s election to require the lender to provide the additional financing. When the lender provided additional financing of $8,000,000 on May 10, 2012, the additional 434,027 of common shares became accessible. Warrants indexed to an additional 260,417 were issued in conjunction with the additional financing.

The following table reflects the issuances of derivative warrants and changes in fair value inputs and assumptions related to the derivative warrants during the three months ended March 31, 2014 and 2013.

The fair value of all warrant derivatives is significantly influenced by our trading market price, the price volatility in trading and the risk free interest components of the Binomial Lattice technique.

NOTE N – REVENUE PARTICIPATION RIGHTS

The Company’s participating revenue rights consisted of the following at March 31, 2014 and December 31, 2013:

	March 31, 2014		December 31, 2013
“Cambridge” project	$	825,000	$	825,000
“Republic” (now “Seattle”) project		62,500		62,500
Galt Resources, LLC (HMS Victory)		3,756,250		3,756,250
Total participating revenue rights	$	4,643,750	$	4,643,750

We previously sold Revenue Participation Certificates (“RPCs”) that represent the right to share in our future revenues derived from the “Cambridge” project, which is now referred to as the HMS Sussex shipwreck project. We also sold RPCs related to a project formerly called the “Republic” project which we now call the “Seattle” project. The “Seattle” project refers to a shipwreck which we have not yet located. The “Cambridge” RPC units constitute restricted securities.

Each $50,000 convertible “Cambridge” RPC entitles the holder to receive a percentage of the gross revenue received by us from the “Cambridge” project, which is defined as all cash proceeds payable to us as a result of the “Cambridge” project, less any amounts paid to the British Government or their designee(s); provided, however, that all funds received by us to finance the project are excluded from gross revenue. The “Cambridge” project holders are entitled to 100% of the first $825,000 of gross revenue, 24.75% of gross revenue from $4 - 35 million, and 12.375% of gross revenue above $35 million generated by the project.

In a private placement that closed in September 2000, we sold “units” consisting of “Republic” Revenue Participation Certificates and Common Stock. Each $50,000 “unit” entitled the holder to 1% of the gross revenue generated by the “Seattle” project (formerly referred to as the “Republic” project), and 100,000 shares of Common Stock. Gross revenue is defined as all cash proceeds payable to us as a result of the “Seattle” project, excluding funds received by us to finance the project.

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 “Cambridge” and “Republic” 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.

In February 2011, we entered into a project syndication deal with Galt Resources LLC (“Galt”) for which they invested $7,512,500 representing rights to future revenues of any one project Galt selected prior to December 31, 2011. If the project is successful and generates sufficient proceeds, Galt will recoup their investment plus three times the investment. Galt’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 Gairsoppa and HMS Victory with the residual 1% on additional net proceeds assigned to the HMS Victory 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 Victory project after they recoup their investment of $3,756,250 plus three times the investment. Galt was paid in full in the amount of $12,506,755 during the first quarter of 2013 for their remaining share of the Gairsoppa project investment. There are no future payments remaining to Galt for the Gairsoppa project nor will they receive or have they received any further distributions from the Gairsoppa project proceeds. Based on the timing of the proceeds earmarked for Galt, the relative corresponding amount of Galt’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 million).

NOTE O – SUBSEQUENT EVENTS

On May 7, 2014, we entered into a new $10.0 million credit facility with Fifth Third bank similar to the loans obtained in 2012 and 2013 for the Gairsoppa project. The bank will advance funds based upon our recovery of valuable cargo from shipwrecks over the coming 12 months. The advances will be pre-defined amounts or percentages of the value of the recovered cargo. The proceeds from our shipwreck recovery contracts or from our sales of recovered cargo will be used to repay the new

21

loan, as was done for the previous Gairsoppa loans. The interest rate on the new loan is a floating rate equal to the one month LIBOR rate plus 500 basis points. An origination fee of $50,000 was payable at closing. A restricted cash deposit of $500,000 is required to cover interest payments when the term loan is advanced.

ITEM 2. MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

The following discussion will assist in the understanding of our financial position and results of operations. The information below should be read in conjunction with the financial statements, the related notes to the financial statements and our Annual Report on Form 10-K for the year ended December 31, 2013.

In addition to historical information, this discussion contains forward-looking statements within the meaning of Section 27A of the Securities Act of 1933 regarding the Company’s expectations concerning its future operations, earnings and prospects. On the date the forward-looking statements are made, the statements represent the Company’s expectations, but the expectations concerning its future operations, earnings and prospects may change. The Company’s expectations involve risks and uncertainties (both favorable and unfavorable) and are based on many assumptions that the Company believes to be reasonable, but such assumptions may ultimately prove to be inaccurate or incomplete, in whole or in part. Accordingly, there can be no assurances that the Company’s expectations and the forward-looking statements will be correct. Please refer to the Company’s most recent Annual Report on Form 10-K for a description of risk factors that could cause actual results to differ (favorably or unfavorably) from the expectations stated in this discussion. Odyssey disclaims any obligation to update any of these forward-looking statements except as required by law.

Operational Update

Additional information regarding our announced projects may be found in our Annual Report on Form 10-K for the year ended December 31, 2013. Only projects with material status updates since those reports were filed are discussed below. We may have other projects in various stages of planning or execution that may not be disclosed for security or legal reasons until considered appropriate by management.

We may use our owned vessel, the Odyssey Explorer, or chartered vessels to conduct operations based on availability.

SS Central America Project

We have been awarded an exclusive contract to conduct an archaeological excavation and recover the remaining valuable cargo from the SS Central America shipwreck located approximately 160 miles off the coast of South Carolina. The ship, which was immortalized in the best-selling book, “Ship of Gold in the Deep Blue Sea,” sank in 1857 with one of the largest documented cargoes of gold ever lost at sea.

Odyssey was selected for the project by Ira Owen Kane, the court-appointed Receiver for Recovery Limited Partnership and Columbus Exploration, LLC. The contract has been approved by the Common Pleas Court of Franklin County, Ohio, which has jurisdiction over the Receivership involving Recovery Limited Partnership and Columbus Exploration LLC. The shipwreck, itself, is under the jurisdiction of the Virginia Court which is currently considering the status of the original arrest made by Columbus America Discovery Group, Inc. acting as the agent for Recovery Limited Partnership, and the most recent arrest initiated by Recovery Limited Partnership to assure its continued salvage rights.

Under the agreement with Recovery Limited Partnership, Odyssey will receive 80% of recovery proceeds until a fixed mobilization fee and a negotiated day rate are paid. Thereafter, Odyssey will receive 45% of the recovery proceeds.

During the transit of Odyssey’s research vessel, the Odyssey Explorer, from the United Kingdom to Charleston, South Carolina, to mobilize for the project, a two hour reconnaissance dive of the site was conducted to assess the current condition of the site. Items appearing to be gold bars were clearly visible on the surface of the site during the dive. Given the reconnaissance purpose of the dive, only five gold bars, two gold coins, a bottle, a piece of pottery, a sample of the shipwreck’s wooden structure and an element of a scientific experiment that was left at the site more than 20 years ago were recovered. The position of the recovered artifacts was documented for archaeological purposes and will be noted in the detailed site plan that is being created. Additional recovery work has been authorized by the United States District Court.

Odyssey commenced operations to conduct the pre-disturbance survey, archaeological excavation, scientific experiments and to recover the remaining gold and other artifacts from the site in April 2014.

22

HMS Victory Project

In 2008, Odyssey discovered the HMS Victory (lost 1744). Odyssey is recognized by the owner and under maritime law, as the salvor-in-possession of the wreck. After a period of joint consultation between the UK Ministry of Defense (MOD) and the UK Department for Culture, Media and Sport, and a public consultation period, the title to the HMS Victory was transferred to the Maritime Heritage Foundation in January 2012. The Foundation, a charity established to locate shipwrecks, investigate, recover and preserve artifacts to the highest archaeological standards and to promote knowledge and understanding of Britain’s maritime heritage, has now assumed responsibility for the future management of the wreck site.

The Foundation has contracted with Odyssey to provide a full range of archaeological, recovery, conservation and other services.

No fieldwork was conducted at the Victory shipwreck site in 2013, however three papers were published, including HMS Victory (Site 25C). Preliminary Results of the Non-Disturbance Shipwreck Survey, 2012 (2013). In addition, a website was created dedicated to HMS Victory (www.victory1744.org) which includes a unique virtual dive trail. Ten archaeological papers and reports about the site are also available on the website at http://www.victory1744.org/publications.html. Additional reports and information about the shipwreck site will be published on this website when approved for release by the Maritime Heritage Foundation.

A detailed project design for the archaeological excavation of the site, including a complete plan for recording, documentation, conservation, publication and public education has been submitted to the UK Ministry of Defence’s Advisory Group. As the exclusive archaeological contractor to the Maritime Heritage Foundation (the owner of the shipwreck), Odyssey is awaiting instructions from the Foundation.

Gairsoppa and Mantola Projects

In 2010, we were awarded the exclusive salvage contract for the cargo of the SS Gairsoppa by the United Kingdom Government (UKG) Department for Transport and in 2011 we were awarded a similar exclusive contract for the SS Mantola. During the period 2012-2013, we recovered 110 tons of silver from the Gairsoppa. All of the silver was monetized in 2012 and 2013 for a total amount of approximately $80 million. A small amount of gold derived from refining the silver was monetized in the first quarter of 2014. During 2012-2013, we also explored part of the Mantola shipwreck, but we were unable to locate the silver cargo during the limited search period.

Under the recovery contract, we assumed the risk and responsibility for the search, cargo recovery, documentation, and marketing of the cargo and will retain 80% of the net salved value after first recouping all our recovery expenses. The recovered cargo remains the property of the UK government until it is monetized, at which time any initial proceeds are first applied to cover the project costs incurred by us and then any remaining proceeds are split 80/20 between us and the UK government.

Pursuant to the salvage contracts, we still have exclusivity to these two shipwrecks. We believe silver still remains on board these two shipwrecks. Given current silver prices, the costs associated with the recovery work on these two shipwrecks, and our other projects underway, we have no immediate plans to work on these two shipwrecks in 2014.

Commodity Wreck Program

In addition to salvage rights on the Gairsoppa and Mantola projects, the Company has negotiated salvage contracts with ship owners that will award 90% of the net recovered cargo value to Odyssey for four separate deep-ocean shipwrecks carrying valuable commodities when they sank. There are additional valuable shipwrecks that do not require salvage agreements that can be added to the program and undertaken while Odyssey has a ship and equipment nearby. Odyssey’s research has also identified numerous other shipwrecks carrying potentially valuable commodity cargos.

Planning is underway to assemble the necessary ships and equipment for the exploration, assessment and recovery of these cargoes. Odyssey recently conducted tests of a new 6,000 meter inspection class ROV, a new 3,000 meter depth capable 7160 hull mounted multi-beam, and a 12khz 6,000 meter echo-sounder which can be utilized on these commodity projects. In addition, an advanced custom 6,000 meter depth capability search system that utilizes dual 7125 multi-beam systems has been ordered with delivery expected in second quarter of 2014 for use on commodity shipwreck search and inspection projects.

Depending on the availability of recovery ships, expert off-shore project managers, and equipment, we plan on pursuing further commodity shipwrecks in the near and medium term. Before initiating recovery efforts on any of these commodity shipwrecks, a reconnaissance trip to the sites is required in order to determine the position and condition of the ships and to define the specific equipment needed for the recovery operations.

Subsea Mineral Mining Exploration Projects

We currently own 6.2 million of Class B non-voting shares of Neptune Minerals, Inc., (“Neptune”) a company focused on discovering and commercializing high-value mineral deposits. In 2013, we extended a convertible loan of $500,000 to Neptune, which was fully reserved for at December 31, 2013. The loan matured on April 26, 2014. The note contained a mandatory conversion clause if the note remained unpaid at maturity. The note was convertible into NMI’s Class A voting shares at $12.00 per share upon maturity. During April 2014, we modified the conversion feature with NMI whereas, during April 2014, the note was converted into 5,225 shares of Class A Preferred non-voting stock. These shares are convertible into 522,500 shares of Class A voting shares. Our current ownership of Neptune is approximately 30%. Neptune holds tenement rights to numerous SMS (Seafloor Massive Sulfides) deposits in the South Pacific that commonly contain high concentrations of copper, zinc, gold, and silver.

In May 2012, we received our final cash payment of $1 million for charter services from Chatham Rock Phosphates, Ltd. We also received 9.3 million shares of Chatham Rock Phosphates Ltd. common stock for charter services valued at $1.7 million (12.2 % of Chatham shares outstanding). Chatham Rock Phosphates Ltd. currently holds a license covering over 4,000 square kilometers off the coast of New Zealand believed to have significant seabed deposits of rock phosphate and other potentially valuable minerals. Since our share acquisition, other major investors have acquired shares that have diluted our position to under 10%. In December 2013, Chatham Rock Phosphates received the governmental mining permit for their tenement area.

In February 2013, we disclosed Odyssey’s ownership interest, through Odyssey Marine Enterprises, Ltd., a wholly owned Bahamian company (“Enterprises”), in Oceanica Resources, S. de R.L., a Panamanian company (“Oceanica”). Oceanica’s subsidiary is in the business of mineral exploration and controls exclusive permits in an area which is contains a large amount of phosphate mineralized material. Phosphate is a key ingredient of fertilizers. In March of 2014, Odyssey completed a first NI 43-101 report on the deposit. Odyssey initially held 77.6 million of Oceanica’s 100.0 million outstanding shares. Subsequently, Enterprises sold and transferred to Mako Resources, LLC (“Mako”) 15.0 million shares for a purchase price of $1.00 per share, or $15 million, and granted Mako options to purchase an additional 15.0 million shares at the purchase price of $2.50 per share before December 31, 2013.

In June 2013, Mako agreed to an early exercise of a portion of these options to purchase 8 million shares at a reduced exercise price of $1.25 per share. As part of Odyssey’s strategy to maintain a control position in Oceanica, in parallel with the early exercise, Odyssey purchased one million shares of Oceanica from another Oceanica shareholder at $1.25 per share in a transaction that provides a one-year option to purchase an additional one million shares at $2.50 per share. This transaction also grants Odyssey voting rights on an additional three million shares of Oceanica held by such other Oceanica shareholder so long as there is no change in control of Odyssey.

An option to purchase an additional one million shares was exercised by Mako on December 30, 2013 for a total amount of $2.5 million. The option exercise expiration date for the remaining six million shares was extended until December 31, 2014 with the following modifications: Odyssey will retain voting rights on these six million shares for three years after they are exercised unless there is a change of control at Odyssey, in which case the voting rights will revert to Mako; the exercise price will increase by $0.08 each month beginning on February 1, 2014; the expiration date will accelerate in the event that 5% or more of Oceanica’s equity is acquired by a third party at a valuation of $500 million or more, or when permits to conduct resource recovery operations are issued by the governing jurisdiction.

Admiralty Legal Proceedings

An admiralty arrest is a legal process in which we may seek recognition from the Court of our salvor-in-possession status for a specific shipwreck, site or cargo. It is the first legal step in establishing our rights to ownership or to a salvage award. If we are able to confirm that any entity has a potential legitimate legal claim to any materials recovered from any shipwreck site, we will provide legal notice to any and all potential claimants and pursue prompt resolutions of all claims.

There are currently no pending admiralty legal proceedings to which we are a party. We have, however entered into a Services Agreement with Recovery Limited Partnership for the salvage of the SS Central America arrested in the United States District Court, Eastern District of Virginia.

Critical Accounting Policies and Changes to Accounting Policies

There have been no material changes in our critical accounting estimates since December 31, 2013, nor have we adopted any accounting policy that has or will have a material impact on our consolidated financial statements.

The explanations that follow are for the three-months ended March 31, 2014, compared to the three-months ended March 31, 2013.

Revenue

Revenue is generated through the sale of recovered cargo such as coins, bullion, artifacts and merchandise, the lease of our themed attraction exhibit and expedition charters.

Total revenue decreased by $0.2 million in 2014 as compared to 2013. The majority of revenues in the first quarter of both years resulted from licensing agreements and the sale of the gold obtained from refining the silver bullion recovered from the Gairsoppa shipwreck. The decrease in total revenue was primarily due to lower exhibit revenue and lower sales of other artifacts.

No costs of sales are associated with most of the revenues generated from Gairsoppa silver sales because under the terms of the agreement with the UK government, the silver is the property of the UK government and we receive 80%, of the proceeds from the monetization of the silver after recouping all of our project costs. We sold intact non-refined Gairsoppa silver bars and other Gairsoppa merchandise from inventory in 2014 which generated cost of sales. These intact non-refined silver bars that were sold in the first quarter of 2014 were acquired from the UK government. Cost of sales is recorded for the sale of each Republic coin.

Operating Expenses

Cost of sales consists of shipwreck recovery costs, grading, conservation, packaging, and shipping costs associated with artifact and merchandise sales. Cost of sales decreased 18% in 2014 versus 2013. Cost of sales is recorded for the sale of each Republic coin or the sale of other items owned by Odyssey. No cost of sales are associated with the revenues generated from the Gairsoppa silver sales because under the terms of the agreement with the UK government, the silver is the property of the UK government and we receive 80% of the proceeds from the monetization of the silver after recouping all of its project costs. We sold intact non-refined Gairsoppa silver bars and other Gairsoppa merchandise from inventory in 2014 which generated cost of sales. These intact non-refined silver bars that were sold in the first quarter of 2014 were acquired from the UK government.

Marketing, general and administrative expenses primarily include all costs within the following departments: Executive, Finance & Accounting, Legal, Information Technology, Human Resources, Marketing & Communications, Sales and Business Development. Marketing, general and administrative expenses were $3.0 million in 2014 as compared to $2.8 million in 2013. The increase of $0.2 million is primarily due to full quarter operations of Oceanica Resources S. de. R.L. (“Oceanica”) and its subsidiary in 2014 as compared to only a partial quarter in 2013.

Operations and research expenses primarily include all costs within Archaeology, Conservation, Exhibits, Research, and Marine operations, which include all vessel and charter operations. Operations and research expenses were $7.1 million in 2014 as compared to $5.7 million in 2013. In the first quarter of 2014, the Odyssey Explorer vessel underwent a five-year class inspection, resulting in increased repair and maintenance expense. The vessel also began repositioning to begin the Central America project. These two factors were the main contributors to a $0.8 million increase in Odyssey Explorer costs. Mineral operations in the first quarter of 2014 showed a $0.8 million increase in expenses as compared to the same period in 2013 mostly due to a full quarter of operations of Oceanica and its subsidiary in 2014. These increases were partially offset by $0.2 million reduction of the Dorado Discovery vessel expenses in the first quarter of 2014.

25

Other Income and Expense

Other income and expense generally consists of interest income on investments offset by interest expense on our bank term and other mortgage loans and convertible notes. It also includes the change in fair value of the derivatives related to our issuance of Series G convertible warrants and senior convertible notes. Total other expense decreased from $1.7 million in 2013 to $0.7 million in 2014 as a result of a drop in interest expense (lower balance of interest-bearing debt in 2014), and the change in the fair value of the derivative financial instruments (see NOTE M). Other expense in 2014 was made up of $0.2 million in expense from the change in the fair value of derivative financial instruments (($0.1) million related to the change in the stock price/volatility, $0.1 million related to the change in the probability of exercise of certain instruments and $0.2 million of other), as well as $0.5 million of expense from interest on our financial debt. Other expense in 2013 was made up primarily of $0.7 million expense from the change in the fair value of derivative financial instruments (($1.2) million related to the change in the stock price/volatility, offset by $0.5 million of other), and by $1.1 million of expenses from interest on the financial debt of the company.

Taxes and Non-Controlling Interest

We made no provision for income taxes in 2014. Although the company has significant tax loss carryforwards, the company was subjected to alternative minimum taxes of $0.2 million in 2013 related to the sale of subsidiary stock.

Starting in 2013, we became the controlling shareholder of Oceanica which was created in the first quarter of 2013. Our financial statements thus include the financial results of Oceanica. Except for intercompany transactions that are eliminated upon consolidation, Oceanica’s revenues and expenses, in their entirety, are shown in our consolidated financial statements. The share of Oceanica’s net losses corresponding to the equity of Oceanica not owned by us is subsequently shown as the “Non-Controlling Interest” in the consolidated statements of operations.

Discussion of Cash Flows

Net cash used by operating activities for the first three months of 2014 was $10.2 million. This amount primarily reflected a net loss before non-controlling interest of $10.4 million offset in part by non-cash items of $1.8 million including depreciation and amortization ($0.6 million), share-based compensation ($0.7 million), notes payable interest accretion and loan fee amortization ($0.3 million), and the change in the fair value of derivative liabilities ($0.2 million, see NOTE M). Other working capital changes (including non-current assets) resulted in a decrease in working capital of $1.6 million which primarily included a $2.1 million decrease in accrued expenses. The decrease in accrued expenses in the first quarter of 2014 resulted primarily from the payment of $1.3 million to the UK on the Gairsoppa project and the payment of other accruals made at the end of 2013. Other changes in working capital in the first quarter of 2014 included a $0.4 million increase in inventory, a $0.3 million decrease in restricted cash, a $0.9 million decrease in other assets, and a $0.4 million decrease in accounts payable.

Net cash used by operating activities for the first three months of 2013 was $16.2 million. This amount primarily reflected an operating loss of $9.7 million offset in part by non-cash items of $2.2 million including depreciation and amortization ($.5 million), share-based compensation ($.7 million), notes payable interest accretion and loan fee amortization ($.7 million), and an unfavorable change in the fair value of derivative liabilities ($.7 million increase to Net Loss, see NOTE M). These non-cash expenses were offset by a $.3 million note payable that was converted to an investment in consolidated entity (“Oceanica”). Other working capital changes (including non-current assets) also provided a decrease in working capital of $8.9 million which primarily included a $10.7 decrease in accrued expenses primarily representing the $12.5 million payment to Galt Resources LLC for the remainder due on the Gairsoppa project proceeds. Other changes included a net decrease in current assets of $1.8 million (primarily relating to the $1.5 million decrease in accounts receivable relating to silver proceeds collected from the Gairsoppa project, and a $.3 million decrease in inventory and restricted cash). These increases in net current assets were offset by net increases of current liabilities, excluding accrued expenses as noted previously, of $.2 million.

26

Cash flows used in investing activities for the first three months of 2014 were $1.6 million. The major equipment purchases in 2014 included $0.7 million for new mineral exploration equipment for the Dorado Discovery and $0.7 million for the Odyssey Explorer which included steelwork, an umbilical cable and a control system for the ROV.

Cash flows used in investing activities for the first three months of 2013 were $2.4 million. The major purchases in the first quarter 2013 included $1.8 million for new mineral exploration equipment for the Dorado Discovery (a state-of-the-art multi-beam system and traction winch). Also included for 2013 was $0.5 million for the Odyssey Explorer which included equipment replacement and a major engine overhaul which extended the useful life of the vessel asset. Another $0.1 million in investing activities for 2013 represented the purchase of other marine and corporate property and equipment.

Cash flows used for financing activities for the first three months of 2014 were $3.7 million which primarily represents repayment of debt obligations. $3.1 million of that amount was for short term notes payable. An additional $0.5 million was a payment on the term loan from Fifth Third Bank. The $10.0 million project loan was paid off using $10.0 million in restricted cash held at Fifth Third Bank. The remaining cash flows used for financing activities were mortgage payments.

Cash flows provided by financing activities for the first three months of 2013 were $19.5 million which primarily represented $15.0 million from the sale of a 15% interest in Oceanica Resources, S. de. R.L., ( “Oceanica”), a majority owned subsidiary (see General Discussion under Other Cash Flow and Equity Areas). Additional cash flow was provided from the exercise of outstanding warrants ($4.6 million) offset by repayment of debt obligations ($.2 million).

Other Cash Flow and Equity Areas

General Discussion

At March 31, 2014, we had cash and cash equivalents of $5.8 million, a decrease of $15.6 million from the December 31, 2013 balance of $21.3 million. This reduction was mainly the result of cash used in operations during the quarter as we prepared our vessel for future projects. The Odyssey Explorer was in port for its five-year inspection work and began to re-position to South Carolina to begin work on the Central America project. We also invested further in preparing the Dorado Discovery and the one-pass drill for future mineral exploration. A full quarter of Oceanica and its subsidiary expenses were included in the consolidated financial statements of 2014.

Financial debt of the company was reduced by $13.4 million in the first quarter of 2014, from a balance of $22.0 million at December 31, 2013 to a balance of $8.6 million at March 31, 2014. The $10 million project loan for the Gairsoppa project that was entered into in July 2013 and which had a maturity date of July 24, 2014, was paid off in full in March 2014. All payments required to be made in the first quarter of 2014 on the convertible senior notes were made in cash.

In March 2014, we announced the selection of Odyssey to conduct the recovery of any remaining valuable cargo on the SS Central America shipwreck.

On May 7, 2014, we entered into a new $10.0 million credit facility with Fifth Third bank similar to the loans obtained in 2012 and 2013 for the Gairsoppa project (see discussion below under “Bank Loans”).

Bank Loans

In 2013, we amended our $5 million term loan with Fifth Third Bank (the “Bank”) so that the maturity date was extended from July 11, 2013 to July 11, 2016. In January 2014 we made a required semi-annual principal payment of $500,000 reducing the outstanding balance to $4.5 million. The facility bears floating interest at the one-month LIBOR rate according to the Wall Street Journal plus 500 basis points. Any prepayments made in full or in part are without premium or penalty. No restricted cash payments will need to be kept on deposit. The term loan is still secured by approximately 25,000 numismatic coins recovered by the Company from the SS Republic shipwreck, which amount will be reduced over the term by the amount of coins sold by the Company. The coins used as collateral are held by a custodian for the security of the Bank. The borrowing base is equal to forty percent (40%) of the eligible coin inventory valued on a rolling twelve month wholesale average value. The Company is required to comply with a number of customary covenants.

On May 7, 2014, we entered into a new $10.0 million credit facility with Fifth Third bank similar to the loans obtained in 2012 and 2013 for the Gairsoppa project. The new loan is not tied to any specific shipwreck project. The bank will advance funds based upon our recovery of valuable cargo from shipwrecks over the coming 12 months. The advances will be pre-defined amounts or percentages of the value of the recovered cargo. The proceeds from our shipwreck recovery contracts or from our sales of recovered cargo will be used to repay the new loan, as was done for the previous Gairsoppa loans. The interest rate on the new loan is a floating rate equal to the one month LIBOR rate plus 500 basis points. An origination fee of $50,000 was payable at closing. A restricted cash deposit of $500,000 is required to cover interest payments when the term loan is advanced.

27

On July 11, 2008, we entered into a mortgage loan with Fifth Third Bank. Pursuant to the Loan Agreement, we borrowed $2,580,000. The loan bears interest at a variable rate equal to the prime rate plus three-fourths of one percent (0.75%) per annum. The loan had an initial maturity date of July 11, 2013, and requires monthly principal payments in the amount of $10,750 plus accrued interest. This loan is secured by a restricted cash balance as well as a first mortgage on our corporate office building. This loan contains customary representations and warranties, affirmative and negative covenants, conditions, and other provisions. In July 2013 when the above noted mortgage was scheduled to mature, we extended it on substantially the same terms that previously existed. The new maturity date is July 2016. As of March 31, 2014, the loan balance outstanding was $1.3 million.

Trends and Uncertainties

Our 2014 business plan requires us to generate new cash inflows during 2014 to effectively allow us to perform our planned projects. We plan to generate new cash inflows through the monetization of shipwreck cargo or our equity stakes in seabed mineral companies, financings, syndications or other partnership opportunities. One or more of the planned shipwreck or mining project monetizations, financings, syndications or partnership opportunities may not be realized which may require us to curtail our desired business plan until we generate additional cash. We can offer no assurance any of our planned projects will be successful in providing additional cash during 2014. We have experienced several years of net losses. Our capacity to generate net income in future periods is dependent upon our success in recovering and monetizing shipwrecks, monetizing our interests in mineral exploration entities, generating income from shipwreck or mineral exploration charters or generating income from other projects. In 2014, we will seek to monetize some of our stake in our mineral exploration shareholdings, recover and monetize cargo from the SS Central America, and generate cash inflows from other projects and opportunities. If cash inflow is not sufficient to meet our desired projected business plan requirements, we will be required to follow our contingency business plan which is based on curtailed expenses and requires less new cash inflows. While we have been successful in generating cash inflows and raising the necessary funds in the past, there can be no assurance that we can continue to do so in 2014.

New Accounting Pronouncements

As of March 31, 2014, the impact of recent accounting pronouncements on our business is not considered to be material.

Off-Balance Sheet Arrangements

We do not engage in off-balance sheet financing arrangements. In particular, we do not have any interest in so-called limited purpose entities, which include special purpose entities (SPEs) and structured finance entities.

ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

Market risk is the exposure to loss resulting from changes in interest rates, foreign currency exchange rates, commodity prices and equity prices. Our term loan and primary mortgage bear interest at variable rates and expose us to interest rate risk. Our term loan bears a variable interest rate based on LIBOR and our primary mortgage bears an interest at a variable rate based on the prime rate. See NOTE I for further detail on these instruments. Both of these instruments expose us to interest rate risk. On our primary mortgage, for an increase of every 100 basis points, our interest obligation increases, at most, by approximately $900 per month until maturity in July 2016. On our term loan, an increase of every 100 basis points to the interest rate increases our interest obligation, at most, by approximately $2,800 per month until maturity in July 2016. If an increase to the rates on these instruments occurs, it will have an adverse effect on our operating cash flows and financial condition but we believe it would not be material. We do not believe we have other material market risk exposure and have not entered into any market risk sensitive instruments to mitigate these risks or for trading or speculative purposes.

ITEM 4. CONTROLS AND PROCEDURES

We maintain a set of disclosure controls and procedures designed to ensure that information required to be disclosed in reports that we file or submit under the Securities Exchange Act of 1934 is recorded, processed, summarized and reported within the time periods specified in Securities and Exchange Commission rules and forms. As of the end of the period covered by this report, based on an evaluation carried out under the supervision and with the participation of our management, including the Chief Executive Officer (CEO) and Chief Financial Officer (CFO), of the effectiveness of our disclosure controls and procedures, the CEO and CFO have concluded that our disclosure controls and procedures are effective. There have been no significant changes in our internal controls over financial reporting during the first quarter of 2014 that have materially affected, or are reasonably likely to materially affect, our internal controls over financial reporting.

PART II. OTHER INFORMATION

ITEM 1. Legal Proceedings

The Company is not currently a party to any litigation other than the admiralty proceedings that may be described in this report. From time to time in the ordinary course of business, we may be subject to or may assert a variety of claims or lawsuits.

See the information set forth under the heading “Operational Update – Admiralty Legal Proceedings” in Part I, Item 2 of this report for disclosure regarding certain admiralty legal proceedings in which we were or are involved. Such information is hereby incorporated by reference into this Part II, Item 1.

ITEM 1A. Risk Factors

For information regarding risk factors, please refer to Item 1A in the Company’s Annual Report on Form 10-K for the year ended December 31, 2013. Investors should consider such risk factors, as well as the risk factor set forth below, prior to making an investment decision with respect to the Company’s securities.

The issuance of shares at conversion prices lower than the market price at the time of conversion and the sale of such shares could adversely affect the price of our common stock.

Some of our outstanding shares may have been acquired from time to time upon conversion of outstanding senior convertible notes at conversion prices that are lower than the market price of our common stock at the time of conversion. Odyssey has agreed to pay each amortization payment due under the notes in shares of Odyssey’s common stock, if certain conditions are met; provided, that Odyssey may, at its option, elect to pay such amortization payments in cash. The conversion rate applicable to any amortization payment in shares of Odyssey’s common stock will be the lower of (a) the then-current conversion price and (b) a price equal to 85.0% of the average of the volume-weighted average price of Odyssey’s shares of common stock for a ten-day period immediately prior to the applicable amortization date. Conversion of the notes at conversion prices that are lower than the market price at the time of conversion and the sale of the shares issued upon conversion could have an adverse effect upon the market price of our common stock.

Exhibit 10.2

NON-REVOLVING LINE OF CREDIT PROMISSORY NOTE

$10,000,000.00 Dated: May 7, 2014

Borrower’s Promise to Pay

For value received, the undersigned, ODYSSEY MARINE EXPLORATION, INC., a Nevada corporation authorized to do business in the State of Florida (the “Borrower”), promises to pay to the order of FIFTH THIRD BANK, an Ohio banking corporation (the “Lender”), the principal sum of TEN MILLION AND NO/100 DOLLARS ($10,000,000.00), together with interest on the principal balance remaining unpaid from time to time at the rates set forth below.

1. Term. The term of this Note is from the date of this Note through May 7, 2015 (the “Maturity Date”).

2. Interest.

(A) The principal sum outstanding shall bear interest at a floating rate per annum equal to 500 basis points (5.00%) above the One-Month LIBOR Rate (the “Interest Rate”). “LIBOR” shall mean a rate per annum (adjusted for the current maximum reserve rate required to be maintained by Lender) effective on any Interest Rate Determination Date, which is equal to the offered rate for deposits in U.S. dollars for a one (1) month period, which rate appears on that page of Bloomberg reporting service, or such similar service as determined by Lender, that displays Intercontinental Exchange Benchmark Administration Ltd. interest settlement rates for deposits in U.S. Dollars, as of 11:00 a.m. (London, England time) two (2) business days prior to the Interest Rate Determination Date; provided, that if no such offered rate appears on such page, the rate used for such Interest Period will be the per annum rate of interest determined by Lender to be the rate at which U.S. dollar deposits for the Interest Period are offered to Lender in the London Inter-Bank market as of 11:00 a.m. (London, England time), on the day that is two (2) business days prior to the Interest Rate Determination Date. The term “Interest Rate Determination Date” means the date this Note is closed and initially funded, and the seventeenth (17th) day of each calendar month thereafter. “Interest Period” shall mean a period of one (1) month, provided, that (x) the initial Interest Period may be less than one month, depending on the initial funding date, and (y) no Interest Period shall extend beyond the Maturity Date.

(B) In addition, notwithstanding anything herein contained to the contrary, if, prior to or during any period with respect to the LIBOR Rate, any change in law, regulation or official directive, or in the interpretation thereof, by any governmental body charged with the administration thereof, shall make it unlawful for Lender to fund or maintain its funding in eurodollars of any portion of the advance subject to the LIBOR Rate or otherwise to give effect to Lender’s obligations as contemplated hereby: (i)

Lender may, by written notice to Borrower, declare Lender’s obligations in respect of the LIBOR Rate to be terminated forthwith, and (ii) the LIBOR Rate with respect to Lender shall forthwith cease to be in effect, and interest shall from and after such date be calculated at the Prime Rate, and interest shall be paid on the first day of each calendar month. Borrower hereby agrees to reimburse and indemnify Lender from all increased costs or fees incurred by Lender subsequent to the date hereof relating to the offering of rates of interest based upon the LIBOR Rate. Borrower’s right to utilize LIBOR Rates as set forth in this Note shall be terminated automatically if Lender, by telephonic notice, shall notify Borrower that 30-day LIBOR Rates are not readily available in the London InterBank Offered Rate Market, or that, by reason of circumstances affecting such Market, adequate and reasonable methods do not exist for ascertaining the rate of interest applicable to such deposits. In such event, amounts outstanding hereunder shall bear interest at a rate equal to Lender’s Prime Rate or such other rate of interest as may be agreed to between Lender and Borrower.

(C) Notwithstanding any provision to the contrary in this Note, in no event shall the interest rate charged on this Note exceed the maximum rate of interest permitted under applicable state and/or federal usury law. Any payment of interest that would be deemed unlawful under applicable law for any reason shall be deemed received on account of, and will automatically be applied to reduce, the principal sum outstanding and any other sums (other than interest) due and payable to Lender under this Note, and the provisions hereof shall be deemed amended to provide for the highest rate of interest permitted under applicable law. All interest shall be computed on the basis of the actual number of days elapsed over a year composed of 360 days. Interest shall accrue from the first date that funds are advanced to Borrower until all sums due hereunder are paid in full.

3. Payments. Principal and interest shall be due and payable as follows:

(a) Payments of accrued interest only, shall be payable monthly commencing June 7, 2014, and continuing on the same day of each month thereafter on the principal outstanding from time to time until the loan Maturity Date, at which time the outstanding indebtedness, whether principal, accrued interest or otherwise, shall be due and payable in full. If any payment on this Note becomes due and payable on a Saturday, Sunday or legal holiday under the laws of the State of Florida, the maturity thereof shall be extended to the next succeeding business day and interest thereon shall be payable at contract rate of interest during such extension.

(b) All outstanding principal shall be due and payable in full on or before May 7, 2015.

All payments shall be made at: 201 E. Kennedy Boulevard, Suite 1800, Tampa, Florida 33602, or at such other place as may be designated in writing by the Lender.

4. Borrower’s Right to Prepay. This Note may be prepaid at any time without penalty.

5. Interest Limitation. Interest payable under this Note or any other payment which would be considered as interest or other charge for the use or loan of money shall never exceed the highest contract rate allowed by law applicable to this loan to be charged by Lender. If the interest or other charges collected or to be collected in connection with this loan exceed the permitted limits, then: (A) any such interest or loan charge shall be reduced by the amount necessary to reduce the charge to the permitted limit; and (B) any sums already collected from Borrower which exceeded permitted limits will be refunded. The Lender may choose to make this refund by reducing the principal owed under this Note or by making a direct payment to Borrower. If a refund reduces principal, the reduction will be treated as a partial prepayment.

6. Borrower’s Failure To Pay As Required.

(A) Late Charge for Overdue Payments. If the Lender has not received the full amount of any monthly payment by the end of ten (10) calendar days after it is due, Borrower will pay a late charge to the Lender equal to 5% of the overdue payment of principal and/ or interest. The payment or collection of any such late charge shall not constitute a waiver of any other right or remedy available to the Lender.

(B) Default. If Borrower fails to pay the full amount of each monthly payment by the end of the ten (10) calendar days after it is due, Borrower will be in default, and upon such default by Borrower, Lender may declare the entire principal and interest then remaining unpaid to be immediately due and payable without further notice or demand, and the entire unpaid principal balance shall bear interest at the “Default Interest Rate”. The “Default Interest Rate” shall be five percent (5%) per annum above the contract interest rate set forth above, but not exceeding 18% per annum.

(C) Acceleration. If Borrower is in default after expiration of any applicable cure periods, the Lender may require Borrower to pay immediately the full amount of principal which has not been paid and all the interest that Borrower owes on that amount without further notice.

(D) No Waiver By Lender. Even if, at a time when Borrower is in default, the Lender does not require Borrower to pay immediately in full as described above, the Lender will still have the right to do so if Borrower is in default at a later time.

(E) Payment of Lender’s Costs and Expenses. If the Lender has required Borrower to pay immediately in full as described above, the Lender will have the right to be paid back by Borrower for all of its costs and expenses in enforcing this Note to the extent not prohibited by applicable law. Those expenses include, for example, reasonable attorneys’ fees whether suit be brought or not, and including such fees and costs in any appellate, bankruptcy or post judgment proceedings.

7. Attorneys’ Fees. All parties liable for the payment of this Note agree to pay the Lender reasonable attorneys’ fees and costs, whether or not an action is brought, for the

services of counsel employed after maturity or default to collect this Note or any principal or interest due hereunder, or to protect the security, if any, or enforce the performance of any other agreement contained in this Note or in any instrument of security executed in connection with this loan, including costs and attorneys’ fees on any garnishment action, or for any appeal, or in any proceedings under the federal Bankruptcy Code or in any post-judgment proceedings.

8. Allocation of Payments. Payments shall be applied by Lender first to any late fees or other expenses of Lender hereunder, then to accrued interest and finally to principal.

9. Giving of Notice. Unless applicable law requires a different method, any notice that must be given to Borrower under this Note will be given by mailing it by first class mail or by delivering it to Borrower at 5215 West Laurel Street, Tampa, Florida 33607, or at a different address if Borrower gives the Lender prior written notice of a different address.

Any notice that must be given to the Lender under this Note will be given by mailing it by first class mail to the Lender at the address stated in Section 3 above or at a different address if Borrower is given a notice of that different address.

10. Set Off. The Borrower shall have no right of set off against the Lender under this Note or under any instruments securing this Note or executed in connection with the loan evidenced hereby. The Lender, however, shall have the right, immediately and without further action by it, to set off against this Note all money owed by the Lender in any capacity to Borrower, whether or not due.

11. Obligations of Persons Under This Note. If more than one person signs this Note, each person is fully obligated to keep all of the promises made in this Note, including the promise to pay the full amount owed. Any person who is a guarantor, surety, or endorser of this Note is obligated to do these things. Any person who takes over these obligations, including the obligations of a guarantor, surety, or endorser of this Note, is also obligated to keep all of the promises made in this Note. The Lender may enforce its rights under this Note against each person individually or against all obligators together. This means that any one of them may be required to pay all of the amounts owed under this Note. This means that any one of them may be required to pay all of the amounts owed under this Note. Notwithstanding the above, the “person” executing this Note as an officer of the Borrower, is not personally liable on this Note obligation.

12. Waivers and Consents. Borrower and any other person who has obligations under this Note waive diligence presentment, protest and demand and also notice of dishonor and non-payment of this Note.

13. This Note Secured by Security Instruments. In addition to the protections given to the Lender under this Note, a Loan Agreement and Collateral Assignment

protects the Lender from possible losses which might result if Borrower does not keep the promises made in this Note. That Loan Agreement and Collateral Assignment describes how and under what conditions Borrower may be required to make immediate payment in full or in part of the amounts owed under this Note.

14. Litigation. Any litigation between the parties brought in connection with this Note or concerning the subject matter hereof prior to closing of the Loan shall only be brought in Hillsborough County, Florida. In any such litigation, the prevailing party shall be entitled to an award of its reasonable attorneys’ fees and costs. The Borrower and any guarantors further knowingly, voluntarily and intentionally, waive any right to trial by jury in respect of any litigation arising out of, under, or in connection with this Note, or the loan.

15. Business Purpose Loan. The Borrower acknowledges that the proceeds of the loan are to be used for business or commercial purposes only, and not for personal, family or household purposes.

16. Cross-Default and Cross-Collateralization of Rate Management Agreements and Rate Management Obligations. “Rate Management Agreement” means any agreement, device or arrangement providing for payments which are related to fluctuations of interest rates, exchange rates, forward rates, or equity prices, including, but not limited to, dollar-denominated or cross-currency interest rate exchange agreements, forward currency exchange agreements, interest rate cap or collar protection agreements, forward rate currency or interest rate options, puts and warrants, and any agreement pertaining to equity derivative transactions (e.g., equity or equity index swaps, options, caps, floors, collars and forwards), including without limitation any ISDA Master Agreement between Borrower and Lender or any affiliate of Fifth Third Bancorp, and any schedules, confirmations and documents and other confirming evidence between the parties confirming transactions thereunder, all whether now existing or hereafter arising, and in each case as amended, modified or supplemented from time to time. “Rate Management Obligations” means any and all obligations of Borrower to Lender or any affiliate of Fifth Third Bancorp, whether absolute, contingent or otherwise and howsoever and whensoever (whether now or hereafter) created, arising, evidenced or acquired (including all renewals, extensions and modifications thereof and substitutions therefore), under or in connection with (i) any and all Rate Management Agreements, and (ii) any and all cancellations, buy-backs, reversals, terminations or assignments of any Rate Management Agreement, but not including those Excluded Rate Management Obligations as defined in the Loan Agreement. Borrower promises to promptly pay all Rate Management Obligations, and perform all of the covenants and obligations under the Rate Management Agreements. Any default under the Rate Management Agreements or failure to pay the Rate Management Obligations when due shall be a default under this Note. The payment and performance of this Note, the Rate Management Agreements and Rate Management Obligations are all secured by the Mortgage and other security agreements.

17. WAIVER OF JURY TRIAL. BORROWER AND LENDER HEREBY KNOWINGLY, VOLUNTARILY AND INTENTIONALLY WAIVE THE RIGHT EITHER MAY HAVE TO A TRIAL BY JURY IN RESPECT TO ANY LITIGATION BASED HEREON, OR ARISING OUT OF, UNDER OR IN CONNECTION WITH THIS NOTE AND ANY AGREEMENT CONTEMPLATED TO BE EXECUTED IN CONJUNCTION HEREWITH, OR ANY COURSE OF CONDUCT, COURSE OF DEALING, STATEMENTS (WHETHER VERBAL OR WRITTEN) OR ACTIONS OF ANY PARTY. THIS PROVISION IS A MATERIAL INDUCEMENT FOR THE LENDER TO MAKE THIS LOAN AND EXTENSIONS OF CREDIT TO BORROWER.

NOTE C – RESTRICTED CASH

As required by the original mortgage loan entered into with Fifth Third Bank (the “Bank”) on July 11, 2008, $500,000 was deposited into an interest-bearing account from which principal and interest payments are made. This mortgage loan has since been extended to July 2016. As extended, the new loan calls for a restricted cash balance of $400,000 to be funded annually for principal and interest payments (see NOTE I).

Accounting Policies [Abstract]

Summary of Significant Accounting Policies

NOTE B – SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

This summary of significant accounting policies of the Company is presented to assist in understanding our financial statements. The financial statements and notes are representations of the Company’s management, who are responsible for their integrity and objectivity, and have prepared them in accordance with our customary accounting practices.

Principles of Consolidation

The consolidated financial statements include the accounts of the Company and its direct and indirect wholly owned subsidiaries, Odyssey Marine Services, Inc., OVH, Inc., Odyssey Retriever, Inc., Odyssey Marine Entertainment, Inc., Odyssey Marine Enterprises, Ltd., Odyssey Marine Management, Ltd., Oceanica Marine Operations, S.R.L., and majority interests in Oceanica Resources, S.R.L. and Exploraciones Oceanicas, S. De R.L. De C.V. 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 non-controlling interest are presented within equity and net income, and are shown separately from the Company’s equity and net income attributable to the Company.

Use of Estimates

Management used estimates and assumptions in preparing these financial statements in accordance with generally accepted accounting principles. 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.

Revenue Recognition and Accounts Receivable

In accordance with Topic A.1. in SAB 13: Revenue Recognition, exhibit and expedition charter revenue is recognized ratably when realized and earned as time passes throughout the contract period as defined by the terms of the agreement. Expenses related to the exhibit and expedition charter revenue are recorded as incurred and presented under the caption “Operations and research” on our Consolidated Statements of Income.

Artifact sales and other may also consist of revenues related to the recovery of bulk silver bullion from the Gairsoppa project that exceeds the directly related operating and recovery expenses. Revenue is recognized when our contractual obligation is completed to deliver the silver bullion to the refining agent, the amount of revenue is reasonably assured based on the London Bullion Market rates and the bullion is in a format ready for sale into the market. 2014 revenue does not contain Gaisoppa project silver sales. Operating and recovery expenses incurred in connection with the Gairsoppa contract consist of vessel-related expenses (ships’ crew, provisions, port fees and charter expenses), fuel, specialized equipment and administrative expenses. These expenses are charged to the Consolidated Statements of Income as incurred and subsequently reimbursed per our contract and recorded as a benefit (credit to expense) in the period we are assured of recoupment.

Artifact sales and other is where we would recognize deferred revenue related to revenue participation rights we previously sold to investors. Upon receipt of funds payable to the investors for their revenue participation rights, revenue would be recognized based upon the percent of investor-related proceeds from the sale of silver as a percentage of total proceeds that investor could earn under the revenue participation agreement.

Under our agreement with the United Kingdom Government for the Gairsoppa project, any proceeds from the recovery of the government-owned silver cargo were first applied as a reimbursement to us for search and recovery expenses related to the project. Any remaining net proceeds from the silver owned by the United Kingdom Government were then split 20/80 between the government and us, respectively. In 2013 the proceeds from the silver sales were sufficient to fully reimburse our expenses and to provide net proceeds that were split between the two parties. The Gairsoppa project revenue recognized by us in 2013 resulted from our share of the net proceeds from the sale of the recovered silver bullion that belonged to the United Kingdom Government. The United Kingdom Government reimburses us for all of the expenses incurred by us to recover their silver. Accordingly, we applied the expense reimbursement credit against our search and recovery expenses in our respective years Consolidated Statement of Income under the caption “Operating Expenses: Operations and Research.”

Bad debts are recorded as identified and, from time to time, a specific reserve allowance will be established when required. A return allowance is established for sales that have a right of return. Accounts receivable is stated net of any recorded allowances.

Cash, Cash Equivalents and Restricted Cash

Cash, 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.

Inventory

Our inventory consists of artifacts recovered from the SS Gairsopa and SS Republic shipwrecks, general branded merchandise and related packaging material. Inventoried costs of recovered artifacts include the costs of recovery, conservation and administrative costs to obtain legal title to the artifacts. Administrative costs are generally legal fees or insurance settlements required in order to obtain clear title. The capitalized recovery costs include direct costs such as vessel and related equipment operations and maintenance, crew and technical labor, fuel, provisions, supplies, port fees and depreciation. Conservation costs include fees paid to conservators for cleaning and preserving the artifacts. We continually monitor the recorded aggregate costs of the artifacts in inventory to ensure these costs do not exceed the net realizable value. Historical sales, publications or available public market data are used to assess market value.

Packaging materials and merchandise are recorded at average cost. We record our inventory at the lower of cost or market.

Costs associated with the above noted items are the costs included in our costs of goods. Vessel costs associated with expedition revenue as well as exhibit costs are not included in cost of goods sold. Vessel costs include, but are not limited to, charter costs, fuel, crew and port fees. Vessel and exhibit costs are included in Operations and research in the Consolidated Statements of Operations. In the case of prior revenues associated with the Gairsoppa project, the United Kingdom owned the silver we sold into the London Bullion Market on their behalf, therefore, there was no associated cost of goods.

Long-Lived Assets

Our policy is to recognize impairment losses relating to long-lived assets in accordance with the ASC topic for Property, Plant and Equipment. Decisions are based on several factors, including, but not limited to, management’s plans for future operations, recent operating results and projected cash flows.

Comprehensive Income

Securities with a maturity greater than three months from purchase date are deemed available-for-sale and carried at fair value. Unrealized gains and losses on these securities are excluded from earnings and reported as a separate component of stockholders’ equity. At March 31, 2014, we did not own securities with a maturity greater than three months.

Property and Equipment and Depreciation

Property and equipment is stated at historical cost. Depreciation is provided using the straight-line method at rates based on the assets’ estimated useful lives, which are normally between three and ten years. Leasehold improvements are amortized over their estimated useful lives or lease term, if shorter. Major overhaul items (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 is shorter. Certain major repair items required by industry standards to ensure a vessel’s seaworthiness also qualify 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 are accounted for under the direct-expensing method and are expensed when incurred.

Earnings Per Share

Basic earnings per share (“EPS”) 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 generates income, the Company calculates basic earnings per share using the two-class method pursuant to ASC 260 Earnings Per Share. The two-class method was required effective with the issuance of the Senior Convertible Note disclosed in Note I because the note qualifies as a participating security, giving the holder the right to receive dividends should dividends be declared on common stock. Under the two-class method, earnings for the 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 converted. The Company does not use the two-class method in periods when it generates a loss as the holder of the Convertible Notes do not participate in losses.

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 if-converted method to compute potential common shares from Preferred Stock, Convertible Notes or other convertible securities. As it relates solely to the Senior Convertible Note, for diluted earnings per share, the Company uses the more dilutive of the if-converted method or two-class 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.

At March 31, 2014 and 2013, weighted average common shares outstanding year-to-date were 83,937,883 and 77,344,388, respectively. For the periods ended March 31, 2014 and 2013, 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.

The potential common shares in the following tables represent potential common shares calculated using the treasury stock method from outstanding options, stock awards and warrants that were excluded from the calculation of diluted EPS:

Income Taxes

Income taxes are accounted for using an asset and liability approach that requires the recognition of deferred tax assets and liabilities for the expected future tax consequences attributable to differences between financial statement carrying amounts of existing assets and liabilities and their respective tax bases. A valuation allowance is provided when it is more likely than not that some portion or the entire deferred tax asset will not be realized.

Stock-based Compensation

Our stock-based compensation is recorded in accordance with the guidance in the ASC topic for Stock-Based Compensation (See NOTE J).

Fair Value of Financial Instruments

Financial instruments consist of cash, evidence of ownership in an entity, and contracts that both (i) 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) conveys to that second entity a contractual right (a) to receive cash or another financial instrument from the first entity, or (b) 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, mortgage and loans payable, and redeemable preferred stock, if any. 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. If any, we carry redeemable preferred stock at historical cost and accrete carrying values to estimated redemption values over the term of the financial instrument.

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 (See NOTE M for additional information). We generally do not use derivative financial instruments to hedge exposures to cash-flow, market or foreign-currency risks. However, in the past, we have entered into certain other financial instruments and contracts, such as the sale and issuance of redeemable preferred stock and freestanding warrants with features that are either (i) not afforded equity classification, (ii) embody risks not clearly and closely related to host contracts, or (iii) may be net-cash settled by the counterparty. As required by ASC 815 – Derivatives and Hedging, 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.

Fair Value Hierarchy

The three levels of inputs that may be used to measure fair value are as follows:

Level 1. Quoted prices in active markets for identical assets or liabilities.

Level 2. Observable inputs other than Level 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 2 inputs also include non-binding market consensus prices that can be corroborated with observable market data, as well as quoted prices that were adjusted for security-specific restrictions.

Level 3. Unobservable inputs to the valuation methodology are significant to the measurement of the fair value of assets or liabilities. Level 3 inputs also include non-binding market consensus prices or non-binding broker quotes that we were unable to corroborate with observable market data.

Redeemable Preferred Stock

If we issue redeemable preferred stock instruments (and, if ever, any other redeemable financial instrument we may enter into) they are initially evaluated for possible classification as a liability in instances where redemption is certain to occur pursuant to ASC 480 – Distinguishing Liabilities from Equity. Redeemable preferred stock classified as a liability is recorded and carried at fair value. Redeemable preferred stock that does not, in its entirety, require liability classification is evaluated for embedded features that may require bifurcation and separate classification as derivative liabilities. In all instances, the classification of the redeemable preferred stock host contract that does not require liability classification is evaluated for equity classification or mezzanine classification based upon the nature of the redemption features. Generally, mandatory redemption requirements or any feature that could require cash redemption for matters not within our control, irrespective of probability of the event occurring, requires classification outside of stockholders’ equity. Redeemable preferred stock that is recorded in the mezzanine section is accreted to its redemption value through charges to stockholders’ equity when redemption is probable using the effective interest method.

Subsequent Events

We have evaluated subsequent events for recognition or disclosure through the date this Form 10-Q is filed with the Securities and Exchange Commission.

Risks And Uncertainties [Abstract]

Concentration of Credit Risk

NOTE L – CONCENTRATION OF CREDIT RISK

We maintain the majority of our cash at one financial institution. At March 31, 2014, our uninsured cash balance was approximately $6.0 million.

Our term loans bear a variable interest rate based on LIBOR and our primary mortgage bears interest at a variable rate based on the prime rate. See NOTE I for further detail on these instruments. These instruments expose us to interest rate risk. On our primary mortgage, for an increase of every 100 basis points, our interest obligation increases by approximately, on average, $906 per month until maturity in July 2016. An increase of 100 basis points to the interest rate on our term loans increases our interest obligation, at most, by approximately, on average, $2,800 per month. See NOTE I. If an increase to the rates on these instruments occurs, it will have an adverse effect on our operating cash flows and financial condition but we believe it would not be material.

Our Series G Convertible Preferred Stock and Warrant Financing Transaction on October 11, 2010, Series G Convertible Preferred Stock and Warrant Settlement Transaction during April 2011, and Senior Convertible Note and Warrant Financing Transaction on November 8, 2011 gave rise to derivative financial instruments. We entered into a Series G Convertible Preferred Stock and Warrant Financing Transaction and the Series G Convertible Preferred Stock and Warrant Settlement Transaction on October 11, 2010 and April 14, 2011, respectively. These transaction have since expired. The Series G Convertible Preferred Stock embodied certain terms and features that both possessed all of the conditions of derivative financial instruments and were not clearly and closely related to the host preferred contract in terms of economic risks and characteristics. These terms and features consist of the embedded conversion option and the related down-round anti-dilution protection provision, the Company’s redemption privilege and the holder’s redemption privilege. Each of the redemption features also embodies the redemption premium payments. Warrants issued with this transaction and the subsequent Settlement Transaction embodied down-round anti-dilution protection and, accordingly, were not afforded equity classification.

As more fully discussed in NOTE I, we entered into the Senior Convertible Note and Warrant Financing Transactions on November 8, 2011 and May 10, 2012. The Senior Convertible Notes embodied certain terms and conditions that were not clearly and closely related to the host debt agreement in terms of economic risks and characteristics. These terms and features consist of the embedded conversion options, certain redemption features and a conversion price reset feature. Warrants issued with this transaction embodied reset price protection and, accordingly, were not afforded equity classification.

Current accounting principles that are provided in ASC 815 - Derivatives and Hedging require derivative financial instruments to be classified in liabilities and carried at fair value with changes recorded in income. In addition, the standards do not permit an issuer to account separately for individual derivative terms and features embedded in hybrid financial instruments that require bifurcation and liability classification as derivative financial instruments. Rather, such terms and features must be bundled together and fair valued as a single, compound embedded derivative. We have selected the Monte Carlo Simulations valuation technique to fair value the compound embedded derivative because we believe that this technique is reflective of all significant assumption types, and ranges of assumption inputs, that market participants would likely consider in transactions involving compound embedded derivatives. Such assumptions include, among other inputs, interest risk assumptions, credit risk assumptions and redemption behaviors in addition to traditional inputs for option models such as market trading volatility and risk free rates. We have selected Binomial Lattice to fair value our warrant derivatives because we believe this technique is reflective of all significant assumption types market participants would likely consider in transactions involving freestanding warrants derivatives. The Monte Carlo Simulations technique is a level three valuation technique because it requires the development of significant internal assumptions in addition to observable market indicators.

Significant inputs and results arising from the Monte Carlo Simulations process are as follows for the compound embedded derivative that has been bifurcated from our Senior Convertible Note and classified in liabilities:

	March 31, 2014	December 31, 2013
Quoted market price on valuation date	$2.29	$2.02
Contractual conversion rate	$3.17	$3.17

The following table reflects the issuances of compound embedded derivatives, redemptions and changes in fair value inputs and assumptions related to the compound embedded derivatives during the three months ended March 31, 2014 and 2013.

Balances at March 31	$	—		$	1,732,257

The fair value of the compound embedded derivative is significantly influenced by our trading market price, the price volatility in trading and the interest components of the Monte Carlo Simulation technique.

On October 11, 2010, we also issued warrants to acquire 1,800,000 of our common shares in connection with the Series G Convertible Preferred Stock Financing. During April 4-8, 2011, we issued warrants to acquire 525,000 of our common shares in connection the Series G Convertible Preferred Stock and Warrant Settlement Transaction. Finally, on November 8, 2011, we issued warrants to acquire 1,302,083 of our common shares in connection with the Senior Convertible Note Financing Transaction. These warrants required liability classification as derivative financial instruments because certain down-round anti-dilution protection or price protection features included in the warrant agreements are not consistent with the concept of equity. We applied the Binomial Lattice valuation technique in estimating the fair value of the warrants because we believe that this technique is most appropriate and reflects all of the assumptions that market participants would likely consider in transactions involving the warrants, including the potential incremental value associated with the down-round anti-dilution protections.

The Binomial Lattice technique is a level three valuation technique because it requires the development of significant internal assumptions in addition to observable market indicators. All remaining warrants linked to 1,725,000 shares of common stock were exercised on October 11, 2013. Therefore, the warrants linked to 1,725,000 shares of common stock were not outstanding as of March 31, 2014 and December 31, 2013. Significant assumptions and utilized in the Binomial Lattice process are as follows for the warrants as of March 31, 2014:

Of the 1,302,083 common shares accessible from the warrant issued on November 8, 2011, 434,027 of those common shares were accessible only based upon the Company’s election to require the lender to provide the additional financing. When the lender provided additional financing of $8,000,000 on May 10, 2012, the additional 434,027 of common shares became accessible. Warrants indexed to an additional 260,417 were issued in conjunction with the additional financing.

Income Taxes

NOTE G – INCOME TAXES

For the quarter ended March 31, 2014, we generated $8.4 million of federal NOL carryforwards and $1.2 million of foreign NOL carryforwards. As of March 31, 2014, the Company had consolidated income tax net operating loss (“NOL”) carryforwards for federal tax purposes of approximately $116.9 million and net operating loss carryforwards for foreign income tax purposes of approximately $10.7 million. The federal NOL carryforwards from 1998 forward will expire in various years beginning in 2018 and ending through the year 2032.

Deferred income tax assets and liabilities are recognized for the estimated future tax consequences attributable to differences between financial statement carrying amounts of existing assets and liabilities and their respective tax bases. Deferred income tax assets and liabilities are measured using enacted tax rates expected to be recovered or settled. We have recorded a net deferred tax asset of $0 at March 31, 2014. As required by the Accounting for Income Taxes topic in the ASC, we have concluded it is more likely than not that those assets would not be realizable without the recovery and rights of ownership or salvage rights of high value shipwrecks or substantial profits from our mining operations and thus a valuation allowance has been recorded as of March 31, 2014. There was no U.S. income tax expense for the three months ended March 31, 2014 due to the generation of net operating losses which were not previously benefited in the Company’s financial statements.

The increase in the valuation allowance as of March 31, 2014 is due to the generation of $9.6 million in net operating loss carryforwards.

The change in the valuation allowance is as follows:

March 31, 2014	$	54,955,172
December 31, 2013		51,625,159
Change in valuation allowance	$	3,330,013

Our estimated annual effective tax rate for first quarter of 2014 is 34.39% while our effective tax rate is 0% because of the full valuation allowance. We have not recognized a material adjustment in the liability for unrecognized tax benefits and have not recorded any provisions for accrued interest and penalties related to uncertain tax positions.

The earliest tax year still subject to examination by a major taxing jurisdiction is 2010.

We are currently in the process of seeking a private letter ruling request with the Internal Revenue Service which will grant us relief to make a late election to carryback our 2008 federal NOL either three, four, or five taxable years preceding the taxable year of the applicable NOL, in lieu of the general two-year carryback period. We would carryback the NOL five years to the 2003 tax year. There would be no cash-tax benefit of the carryback as we had a taxable loss during the 2003 tax year. The benefit of making the 5 year carryback election is that the 2008 NOL will now be able to offset 100 percent of future alternative minimum taxable income instead of only offsetting 90 percent. If the Internal Revenue Service grants us relief we will reverse the prior AMT tax liability in the quarter relief is granted as we will be able to fully offset alternative minimum taxable income instead of only 90 percent.

Investments in Unconsolidated Entities

NOTE F – INVESTMENTS IN UNCONSOLIDATED ENTITIES

Neptune Minerals, Inc.

During the quarter ended December 31, 2009, we invested $500,000 for a 25% interest (five membership units) in SMM Project, LLC (“SMM”) to pursue opportunities in the exploration of deep-ocean gold and copper deposits. SMM purchased a majority interest in Bluewater Metals Pty, Ltd. (“Bluewater”), an Australian company with licenses for mineral exploration of approximately 150,000 square kilometers of ocean floor in territorial waters controlled by four different countries in the South Pacific. In April 2010, SMM was acquired by Dorado Ocean Resources, Ltd. (“DOR”) through a share exchange. At that time, DOR also acquired the remaining interest in Bluewater. We were issued 450 DOR shares in exchange for our surrendered units in SMM. We also acquired an additional 1,200 shares of DOR valued at $2,000,000 that resulted in a 41.25% ownership of DOR. Under the terms of the Share Subscription Agreement, we had the option to pay for this investment in cash, provide marine services to DOR over a three-year period commencing April 2010, or exercise our contractual right to offset against the $2,000,000 marine services accounts receivable owed to us. During 2011, we exercised our contractual right and offset these two amounts. The focus of DOR was on the exploration and monetization of gold- and copper-rich Seafloor Massive Sulfide (“SMS”) deposits.

During 2011, we were engaged by Neptune Minerals, Inc. (“NMI”) and its affiliates to perform marine services relating to deep-sea mining. The agreements provided for payments in cash and shares of Class B non-voting common stock of NMI. In 2011, we earned 2,066,600 shares of the Class B non-voting common stock from these engagements. During this same period, NMI completed a share exchange with DOR shareholders whereby each one outstanding share of DOR was exchanged for 1,000 shares of NMI Class B non-voting common stock. We received 1,650,000 shares of NMI Class B non-voting common stock for our 1,650 DOR shares pursuant to the share exchange. In connection with this share exchange, NMI executed an assignment and assumption agreement, whereby NMI assumed $8,227,675 of the outstanding debt DOR owed to us. Additionally in 2011, we executed a debt conversion agreement with NMI, whereby we converted $2,500,000 of the debt owed to us for 2,500,000 shares of NMI Class B non-voting common stock. We have a net share position in NMI of 6,184,976 Class B non-voting shares, which currently represents an approximate 29.6% ownership interest.

Regarding the debt conversion noted in the preceding paragraph, NMI’s shares were valued at $1.00 based on their most recent capital raise at the time when we executed the debt conversion agreement. Pursuant to that agreement, we converted $2,500,000 of the debt owed to us for 2,500,000 shares of NMI Class B non-voting common stock. All the $8,227,675 receivable was fully reserved for in 2010. Thus the $2,500,000 portion of the debt owed to us had a book basis of zero. When we received the 2,500,000 shares as settlement of this accounts receivable, we took the position that the shares received had a carryover basis of zero until we could convert the shares to cash. Accordingly, no gain or loss was recognized in our financial statements in connection with this transaction.

At March 31, 2014, our share of unrecognized DOR (NMI) losses is $19.7 million. We have not recognized the accumulated $19.7 million in our income statement because these losses exceed our investment in DOR (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. Based on the NMI and DOR transactions described above, we believe it is appropriate to allocate this loss carryforward of $19.7 million to any incremental NMI investment that may be recognized on our balance sheet in excess of zero. The aforementioned loss carryforward is based on NMI’s last unaudited financial statements as of March 31, 2014. We do not have any guaranteed obligations to NMI, nor are we otherwise committed to provide financial support. Even though we were not obligated, during the three-months ended September 30, 2013, we, along with a second creditor, loaned funds to NMI of which our share is $500,000, and this indebtedness is evidenced by a convertible note. This funding was not for the purpose of funding NMI’s prior losses but for current requirements. Per ASC 323-10-35-29: Additional Investment After Suspension of Loss Recognition, we concluded this loan does not increase our ownership nor is it to be considered in-substance stock. Based on the financial position of NMI at December 31, 2013, we reserved for this note in its entirety. This note carried an interest rate of 6% per annum and matured on April 26, 2014. The note contained a mandatory conversion clause if the note remained unpaid at maturity. The note was convertible into NMI’s Class A voting shares at $12.00 per share upon maturity. During April 2014, we modified the conversion feature with NMI whereas, during April 2014, the note was converted into 55,225 shares of Class A Preferred non-voting stock. These shares are convertible into 522,500 shares of Class A voting shares.

Chatham Rock Phosphate, Ltd.

During the period ended June 30, 2012, we performed deep-sea mining exploratory services for Chatham Rock Phosphate, Ltd. (“CRP”) valued at $1,680,000. As payment for these services, CRP issued 9,320,348 of ordinary shares to us. The shares currently represent a 6.5% equity stake in CRP. With CRP being a thinly traded stock on the New Zealand Stock Exchange and guidance per ASC 320: Debt and Equity Securities regarding readily determinable fair value, we believe it was appropriate to not recognize this amount as an asset nor as revenue during that period.

Revenue Participation Rights

NOTE N – REVENUE PARTICIPATION RIGHTS

The Company’s participating revenue rights consisted of the following at March 31, 2014 and December 31, 2013:

	March 31, 2014		December 31, 2013
“Cambridge” project	$	825,000	$	825,000
“Republic” (now “Seattle”) project		62,500		62,500
Galt Resources, LLC (HMS Victory)		3,756,250		3,756,250
Total participating revenue rights	$	4,643,750	$	4,643,750

We previously sold Revenue Participation Certificates (“RPCs”) that represent the right to share in our future revenues derived from the “Cambridge” project, which is now referred to as the HMS Sussex shipwreck project. We also sold RPCs related to a project formerly called the “Republic” project which we now call the “Seattle” project. The “Seattle” project refers to a shipwreck which we have not yet located. The “Cambridge” RPC units constitute restricted securities.

Each $50,000 convertible “Cambridge” RPC entitles the holder to receive a percentage of the gross revenue received by us from the “Cambridge” project, which is defined as all cash proceeds payable to us as a result of the “Cambridge” project, less any amounts paid to the British Government or their designee(s); provided, however, that all funds received by us to finance the project are excluded from gross revenue. The “Cambridge” project holders are entitled to 100% of the first $825,000 of gross revenue, 24.75% of gross revenue from $4 – 35 million, and 12.375% of gross revenue above $35 million generated by the project.

In a private placement that closed in September 2000, we sold “units” consisting of “Republic” Revenue Participation Certificates and Common Stock. Each $50,000 “unit” entitled the holder to 1% of the gross revenue generated by the “Seattle” project (formerly referred to as the “Republic” project), and 100,000 shares of Common Stock. Gross revenue is defined as all cash proceeds payable to us as a result of the “Seattle” project, excluding funds received by us to finance the project.

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 “Cambridge” and “Republic” 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.

In February 2011, we entered into a project syndication deal with Galt Resources LLC (“Galt”) for which they invested $7,512,500 representing rights to future revenues of any one project Galt selected prior to December 31, 2011. If the project is successful and generates sufficient proceeds, Galt will recoup their investment plus three times the investment. Galt’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 Gairsoppa and HMS Victory with the residual 1% on additional net proceeds assigned to the HMS Victory 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 Victory project after they recoup their investment of $3,756,250 plus three times the investment. Galt was paid in full in the amount of $12,506,755 during the first quarter of 2013 for their remaining share of the Gairsoppa project investment. There are no future payments remaining to Galt for the Gairsoppa project nor will they receive or have they received any further distributions from the Gairsoppa project proceeds. Based on the timing of the proceeds earmarked for Galt, the relative corresponding amount of Galt’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 million).

Equity [Abstract]

Stockholders' Equity

NOTE J – STOCKHOLDERS’ EQUITY

Common Stock

In 2013, we issued 3,552,357 shares of common stock, valued at $9,279,887, representing payment for principal and interest on our Initial Note and Additional Note as described in NOTE I

During the three-month period ended March 31, 2013, we issued 2,010,500 shares of common stock to accredited investors upon exercise of their outstanding warrants.

Warrants

We have 2,087,500 warrants outstanding. 1,562,500 warrants are attached to our Senior Convertible debt discussed further in NOTES I and M. The conversion price on these warrants is $3.60 and are set to expire on November 9, 2016. The remaining 525,000 warrants remain were attached to our former Series G Preferred stock. These warrents have a conversion price of $2.44 and expired on April 13, 2014. See NOTE M for further information on these warrants.

Stock-Based Compensation

We have one active stock incentive plan, the 2005 Stock Incentive Plan. The 1997 Stock Incentive Plan expired on August 17, 2007. As of that date, options could no longer be granted from that Plan but any granted and unexercised options continued to exist until exercised or they expired. As of December 31, 2013 all outstanding options in the 1997 Stock Incentive Plan have expired. The 2005 Stock Incentive Plan provides for the grant of incentive stock options, non-qualified stock options, restricted stock awards, restricted stock units and stock appreciation rights. We initially reserved 2,500,000 of our authorized but unissued shares of common stock for issuance under the Plan, and, at the time the Plan was adopted, not more than 500,000 of these shares could be used for restricted stock awards and restricted stock units. On January 16, 2008, the Board of Directors approved amendments to the Plan to add 2,500,000 shares of common stock to the Plan, to allow any number of shares to be used for restricted stock awards, to clarify certain other provisions in the Plan and to submit the amended Plan for stockholder approval. The amended Plan was approved at the annual meeting of stockholders on May 7, 2008. On June 3, 2010, our stockholders’ approved an amendment to the 2005 Stock Incentive Plan which resulted in the addition of 3,000,000 shares of common stock to the Plan. Any incentive option and non-qualified option granted under the Plan must provide for an exercise price of not less than the fair market value of the underlying shares on the date of grant, but the exercise price of any incentive option granted to an officer, director or eligible employee owning more than 10% of our outstanding common stock must not be less than 110% of fair market value on the date of the grant.

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 three-month periods ended March 31, 2014 and 2013 was $492,775 and $688,580.

The weighted average estimated fair value of stock options granted during the three-month periods ended March 31, 2014 and 2013 was $1.28 and $1.44, respectively. The weighted average fair value of stock options granted is determined using the Black-Scholes 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. The Black-Scholes option valuation 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 or variations from these assumptions can materially affect the fair value of the options. The assumptions used in the Black-Scholes model were as follows for stock options granted during the three-month periods ended:

	March 31, 2014	March 31, 2013
Risk-free interest rate	2.11 - 2.66%	.41 - .63%
Expected volatility of common stock	63.54 - 65.03%	64.04 - 68.26%
Dividend yield	0%	0%
Expected life of options	6.1 - 8.2 years	3.0 - 4.1 years

NOTE H – COMMITMENTS AND CONTINGENCIES

Legal Proceedings

The Company may be subject to a variety of other claims and suits that arise from time to time in the ordinary course of business. We are currently not a party to any pending litigation.

Trends and Uncertainties

Our 2014 business plan requires us to generate new cash inflows during 2014 to effectively allow us to perform our planned projects. We plan to generate new cash inflows through the monetization of shipwreck cargo or our equity stakes in seabed mineral companies, financings, syndications or other partnership opportunities. One or more of the planned shipwreck or mining project monetizations, financings, syndications or partnership opportunities may not be realized which may require us to curtail our desired business plan until we generate additional cash. We can offer no assurance any of our planned projects will be successful in providing additional cash during 2014. We have experienced several years of net losses. Our capacity to generate net income in future periods is dependent upon our success in recovering and monetizing shipwrecks, monetizing our interests in mineral exploration entities, generating income from shipwreck or mineral exploration charters or generating income from other projects. In 2014, we will seek to monetize some of our stake in our mineral exploration shareholdings, recover and monetize cargo from the SSCentral America, and generate cash inflows from other projects and opportunities. If cash inflow is not sufficient to meet our desired projected business plan requirements, we will be required to follow our contingency business plan which is based on curtailed expenses and requires less new cash inflows. While we have been successful in generating cash inflows and raising the necessary funds in the past, there can be no assurance that we can continue to do so in 2014.

Mortgage and Loans Payable

NOTE I – MORTGAGE AND LOANS PAYABLE

The Company’s consolidated debt consisted of the following at March 31, 2014 and December 31, 2013:

	March 31, 2014		December 31, 2013
Term loan	$	4,500,000	$	5,000,000

Mortgage payable		1,777,924		1,816,286
	$	8,619,570	$	22,031,808

Term Loan

Our current term loan, which is a result of amending its predecessor during July 2013, has a maturity date in July 2016. This facility bears floating interest at the one month LIBOR rate as reported in the Wall Street Journal plus 500 basis points. Beginning January 2014, we were required to make semi-annual payments of $500,000. Any prepayments made in full or in part were without premium or penalty. No restricted cash payments are required to be kept on deposit. This facility has substantially all the same terms that were attached to its predecessors as disclosed in previous Securities and Exchange Commissions filings.

This term loan is secured by approximately 25,000 numismatic coins recovered from the SS Republic shipwreck, which amount will be reduced over the term by the amount of coins sold by the Company. The coins used as collateral are held by a custodian for the security of the Bank. The carrying value of the borrowing base is not to exceed forty percent (40%) of the eligible coin inventory valued on a rolling twelve-month wholesale average value. The Company is required to comply with a number of customary covenants. The significant covenants include: maintaining insurance on the inventory; ensuring the collateral is free from encumbrances and without the consent of the Bank, the Company cannot merge or consolidate with or into any other corporation or entity nor can the Company enter into a material debt agreement with a third party without approval. We were in compliance with all covenants at March 31, 2014.

Project Term Loan

During July 2013, we entered into a $10.0 million project term loan agreement with Fifth Third Bank. The facility was to mature on July 24, 2014 but was repaid in its entirety during March 2014. This term loan bore interest at a floating rate equal to the one-month LIBOR rate plus 500 basis points. We were able to make prepayments in whole or in part without premium or penalty. An origination fee of $50,000 was paid at closing. A restricted cash deposit of $500,000 was required to cover interest payments. The term loan was secured by $10.0 million that was monetized from approximately 1.8 million ounces of silver recovered from the SS Gairsoppa. We were required to comply with a number of customary affirmative and negative covenants of which we were in compliance during the existence of this facility. The proceeds were used to fund project recovery costs.

Mortgage Payable

On July 11, 2008, we entered into a mortgage loan with Fifth Third Bank. Pursuant to the Loan Agreement, we borrowed $2,580,000. The loan bore interest at a variable rate equal to the prime rate plus three-fourths of one percent (0.75%) per annum. The loan matured on July 11, 2013, and required monthly principal payments in the amount of $10,750 plus accrued interest. This loan was secured by a restricted cash balance as well as a first mortgage on our corporate office building. This loan contained customary representations and warranties, affirmative and negative covenants, conditions, and other provisions.

During July 2013 when the above noted mortgage matured, we extended it on substantially the same terms that previously existed. The new maturity date is July 2016. The loan bears interest at a variable rate equal to the prime rate plus three-fourths of one percent (0.75%) per annum. Monthly principal payments in the amount of $10,750 plus accrued interest are required. This loan is secured by a restricted cash balance (See NOTE C) as well as a first mortgage on our corporate office building. This loan contains customary representations and warranties, affirmative and negative covenants, conditions, and other provisions. As of March 31, 2014, the loan balance outstanding was $1,216,000.

During May 2008, we entered into a mortgage loan in the principal amount of $679,000 with The Bank of Tampa to purchase our conservation lab and storage facility. This obligation has a monthly payment of $5,080 with a maturity date of May 14, 2015. Principal and interest payments are payable monthly. Interest is at a fixed annual rate of 6.45%. This debt is secured by the related mortgaged real property. As of March 31, 2014, the loan balance outstanding was $561,923.

Senior Convertible Notes

Initial Note

During November 2011, we entered into a securities purchase agreement (the “Purchase Agreement”) with one institutional investor pursuant to which we issued and sold a Senior Convertible Note in the original principal amount of $10.0 million (the “Initial Note”) and a warrant (the “Warrant”) to purchase up to 1,302,083 shares of our common stock. Subject to the satisfaction of conditions set forth in the Purchase Agreement, we had the right to require the investor to purchase an additional senior convertible note in the original principal amount of up to $5.0 million on the six-month anniversary of the initial closing date (the “Additional Note” and, collectively “Notes”). Aggregate direct finance costs amounted to $545,000 of which $45,000 related to costs of the lender and, accordingly, were included in the original issue discount on the Initial Note.

The indebtedness evidenced by the Initial Note bears interest at 8.0% percent per year (15% under default conditions, if applicable). Interest is compounded monthly and payable quarterly at the beginning of each calendar quarter. The Initial Note is amortized with equal monthly principal installments of $434,783 that commenced on July 8, 2012. Prepayment is not allowed. Further, the Notes may be converted into our common stock, at the option of the holder, at any time following issuance, with respect to the Initial Note, or at any time following six months after the date of issuance, with respect to the Additional Note. The initial conversion price of the Initial Note was $3.74, subject to adjustment on the six-month anniversary of the initial closing date as follows: The reset conversion price applicable to the Initial Note was to be adjusted to the lesser of (a) the then current conversion price and (b) the greater of (i) $1.44 and (ii) 110.0% of the market price of our common stock on the six-month anniversary of the initial closing date (as applicable, the “Conversion Price”). On May 10, 2012 (the six-month anniversary of the initial closing date), the conversion price applicable to the Initial Note was adjusted to $3.17, which represented 110.0% of the market price of Odyssey’s common stock. The conversion price is also subject to adjustment for stock splits, stock dividends, recapitalizations, and similar transactions. We agreed to pay each amortization payment in shares of our common stock, if certain conditions are met; provided, that we may, at our option, elect to pay such amortization payments in cash. The conversion rate applicable to any amortization payment that we make in shares of our common stock will be the lower of (a) the Conversion Price and (b) a price equal to 85.0% of the average for a ten-day period immediately prior to the applicable amortization date of the volume-weighted average price of our shares of common stock.

The Initial Note provides for redemption upon the occurrence of an event of default. Default conditions include non-servicing of the debt and certain other credit risk related conditions. Default conditions also include certain equity indexed events including failures to file public information documents, non-conversion or insufficient share authorizations to effect conversion and failure to obtain and maintain an effective registration statement covering the underlying common shares. The remedies to the investor for events of default include acceleration of payment at 125% of the remaining face value in certain circumstances. In the event the default redemption is not paid, the investor would have the right to elect conversion of the note at an adjusted conversion price approximating 75% of quoted market prices. A change in control would also result in a redemption requirement at 125% of the face value.

The Notes extend no voting rights to the investors. However, the Notes extend participation rights in dividend payments, if any, made to the holders of the Company’s common or other class of stock, except our Series G Preferred Stock.

The holder of the Initial Note elected to apply some of the payments due on the principal balance of the Initial Note to the Additional Note described below. During the year ended December 31, 2013, we issued 3,282,934 shares of common stock as payment of $8,608,694 in outstanding principal. During the three months ended March 31, 2014, the remaining principal balance of $1,391,306 was paid in full in cash.

Under the terms of the Warrant, the holder is entitled to exercise the Warrant to purchase up to 1,302,083 shares of our common stock at an initial exercise price of $4.32 per share, during the five-year period beginning on the six-month anniversary of the initial closing date; provided, that 434,027 shares of our common stock issuable upon exercise of the Warrant could not be exercised unless the investor purchased the Additional Note. In accordance with the terms of the warrant agreement, on May 10, 2012, the exercise price applicable to the Warrant was adjusted to $3.60 which was the lesser of (a) the then current exercise price and (b) 125.0% of the market price of our common stock on the six-month anniversary of the initial closing date. The Exercise Price is also subject to adjustment for stock splits, stock dividends, recapitalizations, and similar transactions. We are generally prohibited from issuing shares of common stock upon exercise of the Warrant if such exercise would cause us to breach our obligations under the rules or regulations of the stock market on which the common stock is traded.

In connection with the financing, we entered into a registration rights agreement pursuant to which we filed a registration statement with the Securities and Exchange Commission (with the “SEC”) relating to the offer and sale by the investor of the shares of common stock issuable upon conversion of the Notes and the exercise of the Warrant. Pursuant to the agreement, we were required to file the registration statement within six months of the initial closing date and to use best efforts for the registration statement to be declared effective 90 days thereafter (or 120 days thereafter if the registration statement is subject to review by the SEC).

Additional Note

On May 10, 2012, we issued the Additional Note in the original principal amount of $8.0 million, and the number of shares of Odyssey’s common stock issuable upon exercise of the Warrant increased to 1,562,500. The Additional Note bears interest at 9.0% per year and will mature on the 30-month anniversary of the initial closing date. The Additional Note amortizes in equal monthly installments commencing on the eighth-month anniversary of the initial note and may be paid in cash or Odyssey common stock. The Additional Note may be converted into Odyssey’s common stock, at the option of the holder, at any time following six months after the date of issuance. The conversion rate applicable to any amortization payment that we make in shares of our common stock will be the lower of (a) the Conversion Price and (b) a price equal to 85.0% of the average for a ten-day period immediately prior to the applicable amortization date of the volume-weighted average price of our shares of common stock. The initial conversion price of the Additional Note is $3.74, subject to reset on the earlier of the date the registration statement registering the offer and sale of the common stock issuable under the notes and the warrants becomes effective and a prospectus contained therein shall be available for the resale by the holder of all of the registrable securities or the six-month anniversary of the additional closing date. The registration statement was declared effective on July 6, 2012, and there was no reset to the conversion price of the Additional Note.

On January 2, 2013, we entered into an agreement to amend the terms of the Additional Note. The installment payments due December 1, 2012, January 1, 2013 and February 1, 2013 were deferred until March 1, 2013 and the conversion price on the Additional Note was decreased from $3.74 to $3.17. We evaluated the amendment’s impact on the accounting for the Additional Note in accordance with ASC 470-50-40-6 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% and the reduction in the conversion price resulted in a change in the fair value of the embedded conversion option that was less than 10% of the carrying value of the Additional Note immediately prior to the modification. Since the amendment did not result in a substantial modification, extinguishment accounting was not applicable. During the three months ended March 31, 2014, the $1,739,130 of the principal balance was paid in cash. The principal balance of the Additional Note at March 31, 2014 was $2,347,826 which is bifurcated on our balance sheet between derivative liabilities and mortgage and loans payable.

Accounting considerations

We have accounted for the Initial Note, Additional Note and Warrant issued for cash as a financing transaction, wherein the net proceeds that we received were allocated to the financial instruments issued. Prior to making the accounting allocation, we evaluated the Initial Note, Additional Note and the Warrant for proper classification under ASC 480 Distinguishing Liabilities from Equity (“ASC 480”) and ASC 815 Derivatives and Hedging (“ASC 815”).

ASC 815 generally requires the analysis 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 material embedded derivative features consisted of the conversion option and related conversion reset price protection, the Company’s redemption privilege, and certain redemption rights that were indexed to equity risks. The conversion option and conversion reset price protection, along with the redemption features bearing risks of equity, were not clearly and closely related to the host debt agreement and required bifurcation. Current accounting principles that are also provided in ASC 815 do not permit an issuer to account separately for individual derivative terms and features that require bifurcation and liability classification. Rather, such terms and features must be and were bundled together and fair valued as a single, compound embedded derivative.

The Warrant has a term of five and one-half years and at inception, had an initial exercise price of $4.32. The contractual exercise price is subject to adjustment for both traditional recapitalization events and was reset on the sixth month anniversary of issuance to $3.60 per share. Although the warrant did not fall within the scope of ASC 480, the warrant required derivative liability accounting because the conversion price reset protection terms are not consistent with the definition for financial instruments indexed to a company’s own stock.

Based on the previous conclusions, we allocated the cash proceeds first to the derivative components at their fair values (see NOTE M) with the residual allocated to the host debt contract, as follows:

	Allocation
Initial Note	$	4,910,862
Compound embedded derivative		2,989,537
Derivative warrants		2,054,601
	$	9,955,000

The basis that was subject to allocation included the gross proceeds of $10,000,000, less costs of the investor paid out of proceeds that amounted to $45,000. We also allocated the direct financing costs of $500,000 to the note payable and the derivative components based upon the relative fair values of these financial instruments. As a result of this allocation, $246,653 was recorded in deferred costs and $253,347 was recorded as expense.

Allocation of the cash proceeds related to the Additional Financing was as follows:

	Allocation
Additional Note	$	6,339,642
Compound embedded derivative		1,291,298
Derivative warrants		363,542
	$	7,994,482

The basis that was subject to allocation included the gross proceeds of $8,000,000, less costs of the investor paid out of proceeds that amounted to $5,518. We also allocated the direct financing costs of $400,000 to the note payable and the derivative components based upon the relative fair values of these financial instruments. As a result of this allocation, $317,201 was recorded in deferred costs and $82,799 was recorded as expense.

The financing basis allocated to the notes payable and the deferred asset arising from direct finance costs are subject to amortization with periodic charges to interest expense using the effective interest method. Amortization of these components included in interest expense during the three months ended March 31, 2014 and 2013 amounted to $271,606 and $689,333, respectively. The derivative components are subject to re-measurement to fair value at the end of each reporting period with the change reflected in income. See NOTE M for information about our derivatives.

Deferred Revenue

NOTE K – DEFERRED REVENUE

Since 2009, we entered into several marine search services contracts associated with the Robert Frasier Marine, Ltd. projects. For each contract, revenue is recognized over the contractual period when services are performed as defined by the contract. The period of time a search project remains active varies but usually extends over several months and may be accelerated or extended depending upon operational factors. At March 31, 2014, we have a $1,840,404 service obligation on one service contract that will be recognized as revenue over the period of time the contractual services are provided. At December 31, 2013, we had the same service obligation of $1,840,404.

Accounting Policies [Abstract]

Principles of Consolidation

Principles of Consolidation

The consolidated financial statements include the accounts of the Company and its direct and indirect wholly owned subsidiaries, Odyssey Marine Services, Inc., OVH, Inc., Odyssey Retriever, Inc., Odyssey Marine Entertainment, Inc., Odyssey Marine Enterprises, Ltd., Odyssey Marine Management, Ltd., Oceanica Marine Operations, S.R.L., and majority interests in Oceanica Resources, S.R.L. and Exploraciones Oceanicas, S. De R.L. De C.V. 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 non-controlling interest are presented within equity and net income, and are shown separately from the Company’s equity and net income attributable to the Company.

Use of Estimates

Use of Estimates

Management used estimates and assumptions in preparing these financial statements in accordance with generally accepted accounting principles. 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.

Revenue Recognition and Accounts Receivable

Revenue Recognition and Accounts Receivable

In accordance with Topic A.1. in SAB 13: Revenue Recognition, exhibit and expedition charter revenue is recognized ratably when realized and earned as time passes throughout the contract period as defined by the terms of the agreement. Expenses related to the exhibit and expedition charter revenue are recorded as incurred and presented under the caption “Operations and research” on our Consolidated Statements of Income.

Artifact sales and other may also consist of revenues related to the recovery of bulk silver bullion from the Gairsoppa project that exceeds the directly related operating and recovery expenses. Revenue is recognized when our contractual obligation is completed to deliver the silver bullion to the refining agent, the amount of revenue is reasonably assured based on the London Bullion Market rates and the bullion is in a format ready for sale into the market. 2014 revenue does not contain Gaisoppa project silver sales. Operating and recovery expenses incurred in connection with the Gairsoppa contract consist of vessel-related expenses (ships’ crew, provisions, port fees and charter expenses), fuel, specialized equipment and administrative expenses. These expenses are charged to the Consolidated Statements of Income as incurred and subsequently reimbursed per our contract and recorded as a benefit (credit to expense) in the period we are assured of recoupment.

Artifact sales and other is where we would recognize deferred revenue related to revenue participation rights we previously sold to investors. Upon receipt of funds payable to the investors for their revenue participation rights, revenue would be recognized based upon the percent of investor-related proceeds from the sale of silver as a percentage of total proceeds that investor could earn under the revenue participation agreement.

Under our agreement with the United Kingdom Government for the Gairsoppa project, any proceeds from the recovery of the government-owned silver cargo were first applied as a reimbursement to us for search and recovery expenses related to the project. Any remaining net proceeds from the silver owned by the United Kingdom Government were then split 20/80 between the government and us, respectively. In 2013 the proceeds from the silver sales were sufficient to fully reimburse our expenses and to provide net proceeds that were split between the two parties. The Gairsoppa project revenue recognized by us in 2013 resulted from our share of the net proceeds from the sale of the recovered silver bullion that belonged to the United Kingdom Government. The United Kingdom Government reimburses us for all of the expenses incurred by us to recover their silver. Accordingly, we applied the expense reimbursement credit against our search and recovery expenses in our respective years Consolidated Statement of Income under the caption “Operating Expenses: Operations and Research.”

Bad debts are recorded as identified and, from time to time, a specific reserve allowance will be established when required. A return allowance is established for sales that have a right of return. Accounts receivable is stated net of any recorded allowances.

Cash, Cash Equivalents and Restricted Cash

Cash, Cash Equivalents and Restricted Cash

Cash, 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.

Inventory

Inventory

Our inventory consists of artifacts recovered from the SS Gairsopa and SS Republic shipwrecks, general branded merchandise and related packaging material. Inventoried costs of recovered artifacts include the costs of recovery, conservation and administrative costs to obtain legal title to the artifacts. Administrative costs are generally legal fees or insurance settlements required in order to obtain clear title. The capitalized recovery costs include direct costs such as vessel and related equipment operations and maintenance, crew and technical labor, fuel, provisions, supplies, port fees and depreciation. Conservation costs include fees paid to conservators for cleaning and preserving the artifacts. We continually monitor the recorded aggregate costs of the artifacts in inventory to ensure these costs do not exceed the net realizable value. Historical sales, publications or available public market data are used to assess market value.

Packaging materials and merchandise are recorded at average cost. We record our inventory at the lower of cost or market.

Costs associated with the above noted items are the costs included in our costs of goods. Vessel costs associated with expedition revenue as well as exhibit costs are not included in cost of goods sold. Vessel costs include, but are not limited to, charter costs, fuel, crew and port fees. Vessel and exhibit costs are included in Operations and research in the Consolidated Statements of Operations. In the case of prior revenues associated with the Gairsoppa project, the United Kingdom owned the silver we sold into the London Bullion Market on their behalf, therefore, there was no associated cost of goods.

Long-Lived Assets

Long-Lived Assets

Our policy is to recognize impairment losses relating to long-lived assets in accordance with the ASC topic for Property, Plant and Equipment. Decisions are based on several factors, including, but not limited to, management’s plans for future operations, recent operating results and projected cash flows.

Comprehensive Income

Comprehensive Income

Securities with a maturity greater than three months from purchase date are deemed available-for-sale and carried at fair value. Unrealized gains and losses on these securities are excluded from earnings and reported as a separate component of stockholders’ equity. At March 31, 2014, we did not own securities with a maturity greater than three months.

Property and Equipment and Depreciation

Property and Equipment and Depreciation

Property and equipment is stated at historical cost. Depreciation is provided using the straight-line method at rates based on the assets’ estimated useful lives, which are normally between three and ten years. Leasehold improvements are amortized over their estimated useful lives or lease term, if shorter. Major overhaul items (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 is shorter. Certain major repair items required by industry standards to ensure a vessel’s seaworthiness also qualify 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 are accounted for under the direct-expensing method and are expensed when incurred.

Earnings Per Share

Earnings Per Share

Basic earnings per share (“EPS”) 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 generates income, the Company calculates basic earnings per share using the two-class method pursuant to ASC 260 Earnings Per Share. The two-class method was required effective with the issuance of the Senior Convertible Note disclosed in Note I because the note qualifies as a participating security, giving the holder the right to receive dividends should dividends be declared on common stock. Under the two-class method, earnings for the 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 converted. The Company does not use the two-class method in periods when it generates a loss as the holder of the Convertible Notes do not participate in losses.

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 if-converted method to compute potential common shares from Preferred Stock, Convertible Notes or other convertible securities. As it relates solely to the Senior Convertible Note, for diluted earnings per share, the Company uses the more dilutive of the if-converted method or two-class 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.

At March 31, 2014 and 2013, weighted average common shares outstanding year-to-date were 83,937,883 and 77,344,388, respectively. For the periods ended March 31, 2014 and 2013, 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.

The potential common shares in the following tables represent potential common shares calculated using the treasury stock method from outstanding options, stock awards and warrants that were excluded from the calculation of diluted EPS:

	Three Months Ended
	March 31, 2014		March 31, 2013

Potential common shares from out-of-the-money options and warrants were also excluded from the computation of diluted EPS because calculation of the associated potential common shares has an anti-dilutive effect on EPS. The following table lists options and warrants that were excluded from diluted EPS:

Income Taxes

Income Taxes

Income taxes are accounted for using an asset and liability approach that requires the recognition of deferred tax assets and liabilities for the expected future tax consequences attributable to differences between financial statement carrying amounts of existing assets and liabilities and their respective tax bases. A valuation allowance is provided when it is more likely than not that some portion or the entire deferred tax asset will not be realized.

Stock-based Compensation

Stock-based Compensation

Our stock-based compensation is recorded in accordance with the guidance in the ASC topic for Stock-Based Compensation (See NOTE J).

Fair Value of Financial Instruments

Fair Value of Financial Instruments

Financial instruments consist of cash, evidence of ownership in an entity, and contracts that both (i) 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) conveys to that second entity a contractual right (a) to receive cash or another financial instrument from the first entity, or (b) 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, mortgage and loans payable, and redeemable preferred stock, if any. 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. If any, we carry redeemable preferred stock at historical cost and accrete carrying values to estimated redemption values over the term of the financial instrument.

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 (See NOTE M for additional information). We generally do not use derivative financial instruments to hedge exposures to cash-flow, market or foreign-currency risks. However, in the past, we have entered into certain other financial instruments and contracts, such as the sale and issuance of redeemable preferred stock and freestanding warrants with features that are either (i) not afforded equity classification, (ii) embody risks not clearly and closely related to host contracts, or (iii) may be net-cash settled by the counterparty. As required by ASC 815 – Derivatives and Hedging, 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.

Fair Value Hierarchy

The three levels of inputs that may be used to measure fair value are as follows:

Level 1. Quoted prices in active markets for identical assets or liabilities.

Level 2. Observable inputs other than Level 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 2 inputs also include non-binding market consensus prices that can be corroborated with observable market data, as well as quoted prices that were adjusted for security-specific restrictions.

Level 3. Unobservable inputs to the valuation methodology are significant to the measurement of the fair value of assets or liabilities. Level 3 inputs also include non-binding market consensus prices or non-binding broker quotes that we were unable to corroborate with observable market data.

Redeemable Preferred Stock

Redeemable Preferred Stock

If we issue redeemable preferred stock instruments (and, if ever, any other redeemable financial instrument we may enter into) they are initially evaluated for possible classification as a liability in instances where redemption is certain to occur pursuant to ASC 480 – Distinguishing Liabilities from Equity. Redeemable preferred stock classified as a liability is recorded and carried at fair value. Redeemable preferred stock that does not, in its entirety, require liability classification is evaluated for embedded features that may require bifurcation and separate classification as derivative liabilities. In all instances, the classification of the redeemable preferred stock host contract that does not require liability classification is evaluated for equity classification or mezzanine classification based upon the nature of the redemption features. Generally, mandatory redemption requirements or any feature that could require cash redemption for matters not within our control, irrespective of probability of the event occurring, requires classification outside of stockholders’ equity. Redeemable preferred stock that is recorded in the mezzanine section is accreted to its redemption value through charges to stockholders’ equity when redemption is probable using the effective interest method.

Subsequent Events

Subsequent Events

We have evaluated subsequent events for recognition or disclosure through the date this Form 10-Q is filed with the Securities and Exchange Commission.

Investments Debt and Equity Securities Policy

With CRP being a thinly traded stock on the New Zealand Stock Exchange and guidance per ASC 320: Debt and Equity Securities regarding readily determinable fair value, we believe it was appropriate to not recognize this amount as an asset nor as revenue during that period.

NOTE O – SUBSEQUENT EVENTS

On May 7, 2014, we entered into a new $10.0 million credit facility with Fifth Third bank similar to the loans obtained in 2012 and 2013 for the Gairsoppa project. The bank will advance funds based upon our recovery of valuable cargo from shipwrecks over the coming 12 months. The advances will be pre-defined amounts or percentages of the value of the recovered cargo. The proceeds from our shipwreck recovery contracts or from our sales of recovered cargo will be used to repay the new loan, as was done for the previous Gairsoppa loans. The interest rate on the new loan is a floating rate equal to the one month LIBOR rate plus 500 basis points. An origination fee of $50,000 was payable at closing. A restricted cash deposit of $500,000 is required to cover interest payments when the term loan is advanced.
