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

On August 10, 2017, we entered into a Note Purchase Agreement (the "Minosa Purchase Agreement") with MINOSA. Pursuant to the Minosa Purchase Agreement, MINOSA agreed to loan Enterprises up to $3.0 million. During 2017, we borrowed $2.7 million against this facility, and Epsilon Acquisitions LLC ("Epsilon") assigned $2.0 million of its previously held debt to MINOSA. The indebtedness is evidenced by a secured convertible promissory note (the "Minosa Note") and bears interest at a rate equal to 10.0% per annum. Unless otherwise converted as described below, the entire outstanding principal balance under this Minosa Note and all accrued interest and fees are due and payable upon written demand by MINOSA; provided, that MINOSA agreed not make a demand for payment prior to the earlier of (a) an event of default (as defined in the Minosa Note) or (b) a date, which may be no earlier than December 31, 2017, that is at least 60 days subsequent to written notice that MINOSA intends to demand payment. MINOSA has not provided any notice they intend to issue a payment demand notice. We unconditionally and irrevocably guaranteed all of the obligations under the Minosa Purchase Agreement and the Minosa Note. MINOSA has the right to convert all amounts outstanding under the Minosa Note into shares of our common stock upon 75 days’ notice to us or upon a merger, consolidation, third party tender offer, or

similar transaction relating to us at the conversion price of $4.35 per share. During December 2017, MINOSA transferred this indebtedness to its parent company. On July 15, 2021, $404,633 of this indebtedness with accumulated interest of $159,082 was transferred to a director of the Company under the same terms as the original agreement, and that indebtedness continues to be convertible at a conversion price of $4.35 per share. This transaction was reviewed and approved by the independent members of the Company’s board of directors.

Upon the closing of the Minosa Purchase Agreement, along with MINOSA, and Penelope Mining LLC, an affiliate of Minosa ("Penelope"), executed and delivered a Second Amended and Restated Waiver and Consent and Amendment No. 5 to Promissory Note and Amendment No. 2 to Stock Purchase Agreement (the "Second AR Waiver"). Pursuant to the Second AR Waiver, Minosa and Penelope consented to the transactions contemplated by the Minosa Purchase Agreement and waived any breach of any representation or warranty and violation of any covenant in the Stock Purchase Agreement, dated as of March 11, 2015, as amended April 10, 2015 (the "SPA"), by and among us, Minosa, and Penelope, arising out of the Company’s execution and delivery of the Minosa Purchase Agreement and the consummation of the transactions contemplated thereby. Pursuant to the Second AR Waiver, we also waived, and agreed not to exercise our right to terminate the SPA pursuant to Section 8.1(c)(ii) thereto, both (a) until after the earlier of (i) July 1, 2018, (ii) the date that MINOSA fails, refuses, or declines to fund (or otherwise does not fund) any subsequent loan under the Minosa Purchase Agreement and (iii) demand is made for repayment of all or any part of the indebtedness outstanding under the Minosa Note, the Second AR Epsilon Note, or the Promissory Note, dated as of March 11, 2015, as amended (the "SPA Note"), in the principal amount of $14.75 million that was issued by us to MINOSA under the SPA, and (b) unless on or prior to such termination, the Notes are paid in full.

The Second AR Waiver (x) further provides that following any conversion of the indebtedness evidenced by the Minosa Note, Penelope may elect to reduce its commitment to purchase our preferred stock under the SPA by the amount of indebtedness converted by MINOSA and (y) amends the SPA Note to provide that the outstanding principal balance under the SPA Note and all accrued interest and fees are due and payable upon written demand by MINOSA; provided, that Minosa agreed not make a demand for payment prior to the earlier of (a) an event of default (as defined in the Minosa Note) or (b) a date, which may be no earlier than December 31, 2017, that is at least 60 days subsequent to written notice that Minosa intends to demand payment.

The obligations under the Minosa Note may be accelerated upon the occurrence of specified events of default including (a) our failure to pay any amount payable under the Minosa Note on the date due and payable; (b) our failure to perform or observe any term, covenant, or agreement in the Minosa Note or the related documents, subject to a five-day cure period; (c) the occurrence and expiration of all applicable grace periods, if any, of an event of default or material breach by us under any of the other loan documents; (d) the termination of the SPA; (e) commencement of certain specified dissolution, liquidation, insolvency, bankruptcy, reorganization, or similar cases or actions by or against us, in specified circumstances unless dismissed or stayed within 60 days; (f) the entry of a judgment or award against us in excess of $100,000; and (g) the occurrence of a change in control (as defined in the Minosa Note).

Pursuant to second amended and restated pledge agreements (the "Second AR Pledge Agreements") entered into by us in favor of MINOSA, we pledged and granted security interests to MINOSA in (a) the 54 million cuotas (a unit of ownership under Panamanian law) of Oceanica held by us, (b) all notes and other receivables from Oceanica and its subsidiary owed to us, and (c) all of the outstanding equity in our wholly owned subsidiary, Odyssey Marine Enterprises, Ltd.

In connection with the execution and delivery of the Minosa Purchase Agreement, Odyssey and MINOSA entered into a second amended and restated registration rights agreement (the "Second AR Registration Rights Agreement") pursuant to which Odyssey agreed to register the offer and sale of the shares (the "Conversion Shares") of our common stock issuable upon the conversion of the indebtedness evidenced by the Minosa Note. Subject to specified limitations set forth in the Second AR Registration Rights Agreement, including that we are eligible to use Form S-3, the holder of the Minosa Note can require us to register the offer and sale of the Conversion Shares if the aggregate offering price thereof (before any underwriting discounts and commissions) is not less than $3.0 million. In addition, we agreed to file a registration statement relating to the offer and sale of the Conversion Shares on a continuous basis promptly (but in no event later than 60 days after) after the conversion of the Minosa Note into the Conversion Shares and to thereafter use its reasonable best efforts to have such registration statement declared effective by the Securities and Exchange Commission.

On March 3, 2023, Odyssey, Altos Hornos de México, S.A.B. de C.V. (“AHMSA”), MINOSA and Phosphate One LLC (f/k/a Penelope Mining LLC, “Phosphate One” and together with AHMSA and MINOSA, the “AHMSA Parties”) entered into Settlement, Release and Termination Agreement (the “Termination Agreement”).

The transactions contemplated by the Termination Agreement were completed on March 6, 2023.

On March 6, 2023, Odyssey entered into a Release and Termination Agreement with a director of the Company, James S. Pignatelli, to terminate and release a portion of the MINOSA 2 Note assigned to Mr. Pignatelli in 2021, the related Note Purchase Agreement (“NPA”) and the Pledge Agreement.

On March 6, 2023, Odyssey issued a new Unsecured Convertible Promissory Note in the principal amount of $500,000 to Mr. Pignatelli that bears interest at the rate of 10.0% per annum convertible into common stock of Odyssey at a conversion price of $3.78 per share. Pursuant to the Release and Termination Agreement with Mr. Pignatelli noted above, he agreed, in exchange for the issuance of this Unsecured Convertible Promissory Note by Odyssey, to release the assigned portion of the MINOSA 2 note issued by Odyssey Marine Exploration, Inc., a wholly owned subsidiary of the Company, to Mr. Pignatelli in the principal amount of $404,634 and convertible at a conversion price of $4.35 per share, pursuant to which the outstanding aggregate obligation with accrued interest was $630,231.

On June 14, 2019, Odyssey and Exploraciones Oceánicas S. de R.L. de C.V., our Mexican subsidiary ("ExO" and, together with Odyssey, the "Claimholder"), and Poplar Falls LLC (the "Funder") entered into an International Claims Enforcement Agreement (the "Agreement"), pursuant to which the Funder agreed to provide financial assistance to the Claimholder to facilitate the prosecution and recovery of the claim by the Claimholder against the United Mexican States under Chapter Eleven of the North American Free Trade Agreement ("NAFTA") for violations of the Claimholder’s rights under NAFTA related to the development of an undersea phosphate deposit off the coast of Baja Sur, Mexico (the "Project"), on our own behalf and on behalf of ExO and United Mexican States (the "Subject Claim"). Pursuant to the Agreement, the Funder agreed to specified fees and expenses regarding the Subject Claim (the "Claims Payments") incrementally and at the Funder’s sole discretion.

Under the terms of the Agreement, the Funder agreed to make Claims Payments in an aggregate amount not to exceed $6,500,000 (the "Maximum Investment Amount"). The Maximum Investment Amount will be made available to the Claimholder in two phases, as set forth below:

Upon exhaustion of the Phase I Investment Amount, the Claimholder will have the option to request Tranche A of the Phase II Investment Amount, consisting of funding up to $3.5 million ("Tranche A Committed Amount"). Upon exhaustion of the Tranche A Committed Amount, the Claimholder will have the option to request Tranche B of the Phase II Investment Amount, consisting of funding of up to $1.5 million ("Tranche B Committed Amount"). The Claimholder must exercise its option to receive the Tranche A Committed Amount in writing, no less than thirty days before submitting a Funding Request to the Funder under Tranche A. The Claimholder must exercise its option to receive the Tranche B Committed Amount in writing within forty-five days after the exhaustion of the Tranche A Committed Amount. Pursuant to the Agreement, the Claimholder agreed that, upon exercising the Claimholder’s option to receive funds under Phase I, Tranche A of Phase II, or Tranche B of Phase II, the Funder will be the sole source of third-party funding for the specified fees and expenses of the Subject Claim under each respective phase and tranche covered by the option exercised, and the Claimholder will obtain funding for such fees and expenses, only as set forth in the Agreement. The Funder was due closing fee of $80,000 for the

Phase I Investment Amount, and $80,000 for the Phase II Investment Amount to pay third parties in connection with due diligence and other administrative and transaction costs incurred by the Funder prior to and in furtherance of execution of the Agreement.

Upon the Funder making Claims Payments to the Claimholder or its designees in an aggregate amount equal to the Maximum Investment Amount, the Funder has the option to continue funding the specified fees and expenses in relation to the Subject Claim on the same terms and conditions provided in the Agreement. The Funder must exercise its option to continue funding in writing, within thirty days after the Funder has made Claims Payments in an aggregate amount equal to the Maximum Investment Amount. If the Funder exercises its option to continue funding, the parties agreed to attempt in good faith to amend the Agreement to provide the Funder with the right to provide at the Funder’s discretion funding in excess of the Maximum Investment Amount, in an amount up to the greatest amount that may then be reasonably expected to be committed for investment in Subject Claim. If the Funder declines to exercise its option, the Claimholder may negotiate and enter into agreements with one or more third parties to provide funding, which shall be subordinate to the Funder’s rights under the Agreement.

The Agreement provides that the Claimholder may at any time without the consent of the Funder either settle or refuse to settle the Subject Claim for any amount; provided, however, that if the Claimholder settles the Subject Claim without the Funder’s consent, which consent shall not be unreasonably withheld, conditioned, or delayed, the value of the Recovery Percentage (as defined below) will be deemed to be the greater of (a) the Recovery Percentage (under Phase I or Phase II, as applicable), or (b) the total amount of all Claims Payments made in connection with such Subject Claim multiplied by three (3).

If the Claimholder ceases the Subject Claim for any reason other than (a) a full and final arbitral award against the Claimholder or (b) a full and final monetary settlement of the claims, including in particular, for a grant of an environmental permit to the Claimholder allowing it to proceed with the Project (with or without a monetary component), all Claims Payments under Phase I and, if Claimholder has exercised the corresponding option, the Tranche A Committed Amount and Tranche B Committed Amount, shall immediately convert to a senior secured liability of the Claimholder. This sum shall incur an annualized internal rate of return ("IRR") of 50.0% retroactive to the date each Funding Request was paid by the Funder (under Phase I), or, to the conversion date for the Tranche A Committed Amount and Tranche B Committed Amount of Phase II if the Claimholder has exercised the respective option (collectively, the "Conversion Amount"). Such Conversion Amount and any and all accrued IRR shall be payable in-full by the Claimholder within 24 months of the date of such conversion, after which time any outstanding Conversion Amounts, shall accrue an ("IRR") of 100.0%, retroactive to the conversion date (the "Penalty Interest Amount"). The Claimholder will execute such documents and take other actions as necessary to grant the Funder a senior security interest on and over all sums due and owing by the Claimholder in order to secure its obligation to pay the Conversion Amount to the Funder. If the Claimholder ceases the Subject Claim due to the grant of an environmental permit (with or without a monetary component), all Claims Payments under Phase 1 and, if the Claimholder has exercised the corresponding option, the Tranche A Committed Amount and Tranche B Committed Amount shall immediately convert to a senior secured liability of the Claimholder and shall incur an annualized an IRR of 50.0% on the Conversion Amount, from the conversion date. Management has estimated it is more likely than not the Subject Claim will result in the issuance of the environmental permit requiring us to record interest under Generally Accepted Accounting Principles. Reliance should not be placed on this estimate in determining the likely outcome of the Subject Claim.

If, at any time after exercising its option to receive funds under either Tranche A or Tranche B of Phase II, the Claimholder wishes to fund the Subject Claim with its own capital ("Self-Funding") (which excludes any Claims Payments made, either directly or indirectly, by any other third party), the Claimholder shall immediately pay to the Funder the Conversion Amount, provided that this requirement shall not apply if, after the Funder has made Claims Payments in an aggregate amount equal to the Maximum Investment Amount, the Funder does not exercise its option to provide Follow-On Funding.

In the event of any receipt of proceeds resulting from the Subject Claim ("Proceeds"), the Funder shall be entitled to any additional sums above the Conversion Amount to which the Funder is entitled as described below. Should the Claimholder cease the Subject Claim as described above after Self-Funding the Claim, accrued IRR and Penalty Interest shall be calculated and paid to the Funder as set forth above. The Funder’s rights to the Recovery Percentage as defined below shall survive any decision by Claimholder to utilize Self-Funding. The parties acknowledge this Agreement constitutes a sale of the right to a portion of the Proceeds (if any) arising from the Subject Claim as set forth in this Agreement. The Claimholder has relinquished its right to the portion of the proceeds, if any, that the Funder would have the right to as described below. This sale of proceeds is being accounted for under the guidance of ASC 470-10-25 Recognition (Sales of Future Revenues)

On each Distribution Date, distributions of the Proceeds shall be made to the Claimholder and the Funder in accordance with subparagraph (a) or (b) below (the "Recovery Percentage"), as applicable:

The Agreement provides that if no Proceeds are ever paid to or received by the Claimholder or its representatives and if the environmental permit is not issued, the Funder shall have no right of recourse or right of action against the Claimholder or its representatives, or any of their respective property, assets, or undertakings, except as otherwise specifically contemplated by the Agreement. If (a) Proceeds are paid to or received by the Claimholder or its representatives; (b) such Proceeds are promptly applied and/or distributed by the Claimholder or on behalf of the Claimholder in accordance with the terms of the Agreement; and (c) the amount received by the Funder as a result thereof is not sufficient to pay all of the Recovery Percentage and all of the amounts due to the Funder under the Agreement, then (provided that all of the Proceeds which the Funder will ever be entitled to have been paid to or received by the Funder), the Funder shall have no right of recourse or action against the Claimholder or its Representatives, or any of their property, assets, or undertakings, except as otherwise specifically contemplated by the Agreement. Pursuant to the Agreement, the Claimholder acknowledged the Funder’s priority right, title, and interest in any Proceeds, including against any available collateral to secure its obligations under the Agreement, which security interest shall be first in priority as against all other security interests in the Proceeds. The Claimholder also acknowledged and agreed to execute and authorize the filing of a financing statement or similar and to take such other actions in such jurisdictions as the Funder, in its sole discretion, deems necessary and appropriate to perfect such security interest. The Agreement also includes representations and warranties, covenants, conditions, termination and indemnification provisions, and other provisions customary for comparable arrangements.

During 2020, the Funder provided us with $2.0 million of the Arbitration Support Funds, and we incurred $200,000 in related fees that were treated as an additional advance. Upon each funding, the proceeds were allocated between debt and equity for the warrants based on the relative fair value of the two instruments. As a result, there was a debt discount of $1,063,811 which is being amortized over the expected remaining term of the agreement using the effective interest method which is charged to interest expense.

Although the warrants only become exercisable upon the occurrence of future events, they are considered issued for accounting purposes and were valued using a binomial lattice model. The expected volatility assumption was based on the historical volatility of our common stock. The expected life assumption was primarily based on management’s expectations of when the Warrants will become exercisable and the risk-free interest rate for the expected term of the warrant is based on the U.S. Treasury yield curve in effect at the time of measurement.

On December 12, 2020, the Claimholder and the Funder entered into a Second Amended and Restated International Claims Enforcement Agreement (the "Second Restated Agreement") relating to the Subject Claim. Under the terms of the Second Restated Agreement, the Funder has made and agreed to make Claims Payments in an aggregate amount not to exceed $20,000,000 (the "Maximum Investment Amount"). The Second Restated Agreement required the Funder to make Claims Payments in an aggregate amount no greater than $10,000,000 for the purposes of pursuing the Subject Claim to a final award ("Phase III Investment Amount"). We also incurred $200,000 in related fees which were treated as an additional advance. This Second Restated Agreement includes the same representations and warranties, covenants, conditions, termination and indemnification provisions, and other provisions as in the original agreement.

On June 14, 2021, the Claimholder and the Funder entered into a Third Amended and Restated International Claims Enforcement Agreement (the "Third Restated Agreement") relating to the Subject Claim. Under the terms of the Third Restated Agreement, the Funder agreed to make Claims Payments in an aggregate amount not to exceed $25,000,000, an increase of $5.0 million (the "Incremental Amount"). The Third Restated Agreement requires the Claimholder to request $2.5 million of the Incremental Amount (the "First $2.5 Million"). Within 15 days after exhaustion of the First $2.5 Million, the Claimholder may either (a) request the remaining $2.5 million (the "Second $2.5 Million") of the Incremental Amount or (b) notify the Funder that the Claimholder has decided to self-fund the Second $2.5 Million. We also incurred $80,000 in related fees which were treated as an additional advance. This Third Restated Agreement includes the same representations and warranties, covenants, conditions, termination and indemnification provisions, and other provisions as in the original agreement.

On March 6, 2023, the Claimholder and the Funder under the agreement entered into a Waiver and Consent Agreement, pursuant to which, among other things, the Funder consented (i) to consent to allow the Claimholder to fund certain costs and expenses arising from the Subject Claim from the Claimholder’s own capital in an aggregate amount not to exceed $5,000,000, and (ii) Odyssey paid a $1,000,000 nonrefundable waiver fee to the Funder.

For the years ended December 31, 2022, 2021 and 2020, we recorded $295,932, $241,034 and $172,849, respectively, of interest expense from the amortization of the debt discount and $146,896, $133,993 and $52,214 interest from the fee amortization, respectively. The December 31, 2022 and 2021 carrying value of the debt is $24,347,513 and $18,323,097, respectively, and is net of unamortized debt fees of $$146,897 and $293,793, respectively, as well as the net unamortized debt discount of $353,996 and $649,928, respectively, associated with the fair value of the warrant. The total face value of this obligation at December 31, 2022 and 2021 was $24,848,406 and $19,266,818, respectively.

On June 26, 2020, we executed the standard loan documents required for securing an Economic Injury Disaster Loan (the "EIDL Loan") from the United States Small Business Administration (the "SBA"). The principal amount of the EIDL Loan is $149,900, with proceeds to be used for working capital purposes. Interest on the EIDL Loan accrues at the rate of 3.75% per annum and installment payments, including principal and interest of $731, are due monthly beginning 12 months from the date of the EIDL Loan. In 2021, the SBA extended this 12 month period, setting the first payment due date in December 2022. The balance of principal and interest is payable thirty years from the date of the promissory note. In connection with the EIDL Loan, the Company executed the EIDL Loan documents, which include the SBA Secured Disaster Loan Note, dated May 16, 2020, the Loan Authorization and Agreement, dated May 16, 2020, and the Security Agreement, dated May 16, 2020, each between the SBA and the Company.

We currently owe a vendor $484,009 as an interest-bearing trade payable. This trade payable bears simple annual interest at a rate of 12%. As collateral, we granted the vendor a primary lien on certain of our equipment. The carrying value of this equipment is zero. This agreement matured in August 2018. During the period ended June 30, 2018, we sold various marine equipment to Magellan for $1.0 million and the assumption of this vendor’s trade payable and accrued interest, however, we remain as guarantor on this trade payable. Included in this equipment is the equipment noted above the vendor has a primary lien on. The vendor consented to Magellan’s assumption of this debt but did not release us from our obligations. If Magellan defaults and the vendor forecloses on this equipment currently in Magellan’s possession, we would then have a contingent liability to Magellan in the amount of $0.5 million for two of the key assets. The Company subsequently received back one of the two key assets thus reducing the contingent liability to $0.3 million.

On October 4, 2021, we and Monaco Financial, LLC and certain associated entities (collectively with Monaco, the "Monaco Parties") entered into a Termination and Settlement Agreement (the "Termination Agreement"). We were parties to various loan arrangements and other commercial contractual relationships, and the purposes of the Termination Agreement were to terminate the loan agreements and contractual relationships and to settle the outstanding obligations thereunder between us and the Monaco Parties.

Pursuant to the Termination Agreement, the loan agreements and contractual relationships were terminated, and we agreed to (a) issue 984,848 shares of our common stock (the "Settlement Shares") to Monaco and (b) pay Monaco an aggregate amount of $3.0 million (the "Settlement Cash") no later than December 1, 2021. The Settlement Shares were issued at a price equal to $6.60 per share, totaling $6.5 million, which was negotiated by the parties with reference to the recent market prices of our common stock and the other terms of the Termination Agreement. We delivered $500,000 of the Settlement Cash to Monaco upon execution and delivery of the Termination Agreement. At Monaco’s option, Monaco has the right, but not the obligation, to receive the remaining $2.5 million in shares of our common stock rather than in cash. This amount was to be settled December 1, 2021 but remained outstanding at December 1, 2021. This indebtedness does not carry an interest rate. Under the terms of the Termination Agreement, (a) the Monaco Parties agreed that approximately $14.5 million of indebtedness, which included accrued interest, owed by us to the Monaco Parties was satisfied in full and (b) certain of the Monaco Parties assigned to us all of their right, title, and interest in a portion of the proceeds from a specified shipwreck project. As a result of the termination of the loan agreements and contractual relationships, (x) our right to receive a percentage of the proceeds derived by the Monaco Parties from certain shipwreck projects was terminated, and (y) Monaco’s option to convert certain indebtedness held by it into shares of Oceanica Resources, S. de R.L. held indirectly by us was terminated. The Termination Agreement also set forth mutual releases and other customary representations, warranties, and covenants of the parties. The Company determined that the embedded conversion feature was clearly and closely related to the host contract and met the scope exception under FASB ASC 815-40. Thus, it did not require derivative liability classification under ASC 815. The Company then evaluated the conversion feature under FASB ASC 470-20,"Debt with conversion and other options" for consideration of any beneficial conversion features ("BCF"). Based on the market price of the common stock on the date of the agreement as compared to the conversion price, they determined there was a BCF of 232,175 which was recorded in additional paid-in capital. A BCF results in a debt discount which should be amortized over the stated maturity of the convertible instrument, or the earliest potential conversion date. Since the contract was convertible upon issuance, the discount was immediately accreted and charged to interest expense.

As a result of the Termination Agreement, we recognized a gain on debt settlement of approximately $5.2 million, which represented the difference between the loan principal, accrued interest and accounts payable forgiven of approximately $14.7 million and total consideration given of approximately $9.5 million.

The shares of common stock issuable under the Termination Agreement were offered and sold pursuant to a base prospectus and a prospectus supplement, both filed pursuant to Odyssey’s shelf registration statement on Form S-3(File No. 0333-227666).

On June 14, 2022, the Company paid $2,500,000 of the outstanding amounts payable under the Termination Agreement with Monaco.

On December 2, 2022, we executed an Amended and Restated Purchase and Sale Agreement ("Purchase and Sale Agreement") with the seller of certain marine equipment ("Seller"). Pursuant to the Purchase and Sale Agreement, Seller agreed to sell us the marine equipment, related tooling items and spares for $2.5 million. On or before the closing date, Odyssey paid the Seller $1.1 million for the acquisition of the assets. Pursuant to the Purchase and Sale Agreement, we paid the Seller the $1.4 million balance of the purchase price as a fully amortizing loan, bearing interest at a rate of 20% per annum, maturing on June 5, 2024 (the "Seller Note").

On November 1, 2022, we executed the Premium Finance Agreement with AFCO Credit Corporation ("AFCO"). Pursuant to the Premium Finance Agreement, AFCO agreed to finance the D&O Insurance premiums evidenced by the promissory note, bearing interest at a rate of 4.95% per annum, maturing on October 31, 2023. On December 1, 2021, we executed the Premium Finance Agreement with AFCO Credit Corporation ("AFCO"). Pursuant to the Premium Finance Agreement, AFCO agreed to finance the D&O Insurance premiums evidenced by the promissory note, bearing interest at a rate of 2% per annum, that matured on November 30, 2022.

On March 7, 2022, we entered into a Note Purchase Agreement (“Note Agreement”) with 37North SPV 11, LLC (“37N”) in which 37N agreed to loan us up to $2,000,000. These loan proceeds were received in full on March 25, 2022. Pursuant to the Note Agreement, the indebtedness was non-interest bearing and matured on June 25, 2022. Anytime from 30 days after the maturity date, 37N had the option to convert all or a portion of the outstanding amount of the indebtedness into conversion shares equal to the quotient obtained by dividing (A) 125% of the amount of the indebtedness, by (B) the lower of $5.94 and 70% of the 10-day VWAP. The aggregate maximum number of shares of Common Stock to be issued in connection with conversion of the indebtedness was not to exceed (i) 19.9% of the outstanding shares of Common Stock prior to the date of the Note Agreement, (ii) 19.9% of the combined voting power of the outstanding voting securities, or iii) exceed the applicable listing rules of the Principal Market if the stockholders did not approve the issuance of Common Stock upon conversion of the indebtedness.

Any time prior to maturity, we had the option to prepay the indebtedness at an amount of 110% of the unpaid principal. From the maturity date to 29 days after the maturity date (July 24, 2022), we were permitted to prepay all (but not less than) an amount equal to 115% of the unpaid amount of the indebtedness. Anytime, after the 30th day after the maturity date (July 25, 2022), we were permitted to prepay all (but not less than) an amount equal to 125% of the unpaid amount of the indebtedness, however, we were required to provide 37N a prepayment notice at least 10 days prior to repayment. If 37N delivered an exercise notice during this 10-day period, the Note would be converted, rather than prepaid.

If 37N delivered an exercise notice and the number of shares issuable is limited by the 19.9% limitation outlined above, then we were permitted to prepay all (but not less than all) an amount equal to 130% of the remaining unpaid amount.

On June 29, 2022, the Company paid $2,200,000 of the outstanding amounts payable under the Note Agreement with 37N. On July 6, 2022, the Company paid the remaining $100,000 of the outstanding amounts payable under the Note Agreement with 37N.

We evaluated the indebtedness and determined the shares issuable pursuant to the conversion option were determinate due to the cap on the number of issuable shares, and, as such, met the requirements for a derivative scope exception for instruments that are both indexed to an entity’s own stock and classified in stockholders’ equity. The optional and contingent prepayment options provide the right to accelerate the settlement of debt; however, the prepayment options can only be exercised by the Company. As such, they are considered clearly and closely related to the debt host instrument and bifurcation was not necessary. We early adopted ASC 2020-06, so we were not required to analyze the instrument for a beneficial conversion feature, and the instrument was recorded wholly as debt. Although the indebtedness did not bear interest, it was required to be repaid at amounts greater than the face value. According to ASC 470-10-35-2, if a debt instrument has a contractual maturity date that can be extended at the issuer’s option, at an increasing rate, the debt discounts and issuance costs must be amortized over the period in which the debt is estimated to be outstanding, even if that period extends beyond the debt’s original contractual maturity date. The difference between the proceeds received and the repayment

amount are generally amortized over the expected life of the indebtedness using the effective interest method. Management estimated the expected life to be very limited, so the entire expected repayment amount of $2.2 million, representing 110% of the indebtedness, was recorded upon issuance of the Note Agreement.

Certain default put provisions were not considered to be clearly and closely related to the debt host, but management concluded that the value of these default put provisions was de minimis.

On February 28, 2023, Odyssey issued a $300,000 11.0% Promissory Note to Galileo NCC Inc ("Galileo"). The Promissory Note was payable on April 1, 2023. On March 6, 2023, Odyssey repaid this note payable in full with proceeds from the issuance of the Note (as defined below).

On March 6, 2023, Odyssey entered into a Note and Warrant Purchase Agreement (the “Purchase Agreement”) with an institutional investor pursuant to which Odyssey issued and sold to the investor (a) a promissory note (the “Note”) in the principal amount of up to $14.0 million and (b) a warrant (the “Warrant” and, together with the Note, the “Securities”) to purchase shares of Odyssey’s common stock.

The principal amount outstanding under the Note bears interest at the rate of 11.0% per annum, and interest is payable in cash on a quarterly basis, except that, (a) at Odyssey’s option and upon notice to the holder of the Note, any quarterly interest payment may be satisfied, in lieu of paying such cash interest, by adding an equivalent amount to the principal amount of the Note (“PIK Interest”), and (b) the first quarterly interest payment due under the Note will be satisfied with PIK Interest. The Note provides Odyssey with the right, but not the obligation, upon notice to the holder of the Note to redeem (x) at any time before the first anniversary of the issuance of the Note, all or any portion of the indebtedness outstanding under the Note (together with all accrued and unpaid interest, including PIK Interest) for an amount equal to one hundred twenty percent (120%) of the outstanding principal amount so being redeemed, and (y) at any time on or after the first anniversary of the issuance of the Note, all or any portion of the indebtedness outstanding under the Note (together with all accrued and unpaid interest, including PIK Interest). Unless the Note is sooner redeemed at Odyssey’s option, all indebtedness under the Note is due and payable on September 6, 2024. Under the terms of the Purchase Agreement, Odyssey agreed to use the proceeds of the sale of the Securities to fund Odyssey’s obligations under the Termination Agreement (as defined below), to pay legal fees and costs related to Odyssey’s NAFTA arbitration against the United Mexican States, to pay fees and expenses related to the transactions contemplated by the Purchase Agreement, and for working capital and other general corporate expenditures. Odyssey’s obligations under Note are secured by a security interest in substantially all of Odyssey’s assets (subject to limited stated exclusions).

Under the terms of the Warrant, the holder has the right for a period of three years after issuance to purchase up to 3,703,704 shares of Odyssey’s common stock at an exercise price of $3.78 per share, which represents 120.0% of the official closing price of Odyssey’s common stock on the NASDAQ Capital Market immediately preceding the signing of the Purchase Agreement, upon delivery of a notice of exercise to Odyssey. Upon exercise of the Warrant, Odyssey has the option to either (a) deliver the shares of common stock issuable upon exercise or (b) pay to the holder an amount equal to the difference between (i) the aggregate exercise price payable under the notice of exercise and (ii) the product of (A) the number of shares of common stock indicated in the notice of exercise multiplied by (B) the arithmetic average of the daily volume-weighted average price of the common stock on the NASDAQ Capital Market for the five consecutive trading days ending on, and including, the trading day immediately prior to the date of the notice of exercise. The warrant provides for customary adjustments to the exercise price and the number of shares of common stock issuable upon exercise in the event of a stock split, recapitalization, reclassification, combination or exchange of shares, separation, reorganization, liquidation, or the like.

In connection with the execution and delivery of the Purchase Agreement, Odyssey entered into a registration rights agreement (the “Registration Rights Agreement”) pursuant to which Odyssey agreed to register the offer and sale of the shares (the “Exercise Shares”) of Odyssey common stock issuable upon exercise of the Warrant. Pursuant to the Registration Rights Agreement, Odyssey agreed to prepare and file with the Securities and Exchange Commission (the “SEC”) a registration statement covering the resale of the Exercise Shares and to use its reasonable best efforts to have the registration statement declared effective by the SEC as soon as practicable thereafter, subject to stated deadlines.
