Odyssey Marine Exploration, Inc. is engaged in the archaeologically sensitive exploration and recovery of deep-water shipwrecks throughout the world. We employ advanced state-of-the-art technology, including side scan sonar, remotely operated vehicles, or ROVs, and other advanced technology, that enables us to locate and recover shipwrecks at depths that were previously unreachable in an economically feasible manner. Odyssey continues to build on a foundation of shipwreck research, development of political relationships and advancement of techniques for deep ocean search and recovery. Odyssey is a Nevada corporation formed on March 5, 1986.

Our vision is to become the world leader in deep-ocean shipwreck exploration, archeological excavation, education, entertainment, and marketing of shipwreck cargoes and related merchandise.

The Company manages and evaluates the operating results of the business in two primary segments: shipwreck exploration and themed attractions.

Shipwreck Exploration – This segment includes all operating activities for exploration and recovery of deep-ocean shipwrecks including the marketing, promotion and distribution of recovered artifacts, replicas, merchandise and books through various retail and wholesale sales channels. The departments included within this group include our marine operations, archaeology, conservation and research, marketing, sales and corporate administration.

Marine operations is tasked with the discovery and recovery of deep-ocean shipwrecks utilizing state-of-the-art technology, including side scan sonar, remotely operated vehicles (ROVs), and other advanced technology. They oversee ships, offshore technology, and ship and technical crews. The marine operations team has also developed proprietary procedures, software and equipment to improve the quality and speed of deep-ocean shipwreck operations.

Our archaeology, conservation and research department supports marine operations by providing target information as well as conducting historical research on artifacts recovered from shipwrecks. After recovered items are returned to shore, our conservation department stabilizes the artifacts and ultimately brings them to their final state of conservation. This department also provides the curation of company-owned artifacts.

Our marketing and sales department includes support functions for the promotion and distribution of products through both retail and wholesale channels. Our direct retail sales efforts provide an alternative distribution channel for our shipwreck products. In addition to obtaining retail pricing through direct channels, the marketing team is building a client base of customers interested in shipwreck collectibles.

Our shipwreck exploration segment continues to rely significantly on the recovered shipwreck cargoes as a primary source of raw materials. The availability of raw materials is primarily dependent on the success of finding intrinsically valuable cargoes from shipwrecks. If we are not successful in the exploration and recovery of shipwrecks, we may not have sufficient raw materials to sell (see Item 1A. Risk Factors).

Our corporate administrative department oversees all aspects of business management and reporting including compliance. The department is also responsible for public and investor relations, finance and accounting, information technology, legal and human resources.

Themed Attractions – Our themed attractions group is responsible for interactive attractions and exhibits that entertain and educate multi-generational audiences, and present Odyssey’s unique shipwreck stories and artifacts. The exhibits showcase our proprietary technologies and the excitement of deep-ocean archeological shipwreck search and recovery. On June 8, 2005, we announced that a newly formed subsidiary, Odyssey Marine Entertainment, Inc., would open an interactive shipwreck and treasure attraction in the French Quarter of New Orleans, Louisiana. Located in the Jax Brewery, Odyssey’s Shipwreck & Treasure Adventure appeals to the universal fascination with shipwrecks and sunken treasure. The attraction tells the stories behind some of the world’s most famous shipwrecks, their treasure and historical artifacts, and allows visitors to experience the adventure and excitement of deep-ocean shipwreck exploration through multiple hands-on interactive exhibits.

We held the grand opening of our first themed attraction, Odyssey’s Shipwreck & Treasure Adventure, on August 27, 2005, at the Jax Brewery complex in the French Quarter of New Orleans. The attraction was closed early on the grand opening day due to Hurricane Katrina. The Jax Brewery building in which the attraction resides remained closed until February 2006. The Odyssey attraction sustained minimal damage and we were able to safely remove all irreplaceable artifacts and valuables including coins and other high-value items. Odyssey carries $4.5 million of insurance coverage for the attraction including property and business income. A preliminary insurance claim was filed in January 2006, however, we presently cannot estimate the amount of insurance proceeds we may receive. On February 15, 2006, we re-opened Odyssey’s Shipwreck & Treasure Adventure in New Orleans. Unlike the rest of the city, the French Quarter escaped mostly intact and tourists are returning to the area. We are currently evaluating our business alternatives for our second attraction currently in development.

Note: The themed attractions segment began in 2005. Financial information for our shipwreck exploration segment for the years 2003 and 2004 can be found in the consolidated financial statements included in Item 15. of this annual report.

Since 1994, we have spent much of our time and resources conducting research in an attempt to identify shipwreck projects that meet the following criteria:

The United Nations Educational Scientific and Cultural Organization, or UNESCO, has estimated that there are up to 3,000,000 shipwrecks contained within the oceans of the world. Historical records suggest that many were lost with verifiable cargoes of intrinsically valuable material.

Odyssey is a pioneer in the use of advanced deep-ocean technology for shipwreck exploration. We are not, for the most part, inventors of the technologies required for deep ocean search and recovery. We use technologies that others, primarily the military, oil industry, and telecommunications industry, have developed at great expense.

We have learned how to apply these technologies specifically to locate shipwrecks and to conduct precise archaeological recoveries at depths of 100 to 2,000 meters and beyond. Although we tend to use “off the shelf” technology because it is cost effective, we do have several proprietary software and equipment applications that maximize the effectiveness of our search and recovery systems. Software that precisely documents the archaeological excavation and advanced sediment removal and filtration systems are two examples of our technological innovations.

Most of our projects are conducted in two phases. The search phase is usually conducted from a smaller vessel outfitted with survey equipment and an inspection ROV. The recovery phase requires a vessel equipped with a work-class ROV, sophisticated positioning systems, and certain Odyssey technology and proprietary software, which allows us to record the recovery in an archaeologically sound manner.

In 2003, we purchased the 113-foot search and survey vessel RV Odyssey and equipped it with sophisticated search and identification equipment. That ship and search team successfully concluded the SS Republic search operation with discovery of the shipwreck in August 2003. Prior to 2005, the RV Odyssey was our primary search vessel for coastal projects. This vessel operates with a minimum ship’s crew of five and a technical crew of two to four.

During 2003, we purchased a 251-foot dynamically-positioned ship named Odyssey Explorer and a 2,500 meter 200-HP work-class ROV that we nicknamed ZEUS. Coupled with a sophisticated suite of cameras, lighting and positioning equipment, as well as advanced computer monitoring and proprietary data management systems, ZEUS provides us the ability to perform extensive archaeological excavation work to depths of 2,500 meters.

The Odyssey Explorer and Zeus were mobilized in Baltimore and deployed to the SS Republic site in October 2003, where they conducted the archaeological excavation of the SS Republic shipwreck site and recovered over 51,000 gold and silver coins and approximately 14,000 other artifacts prior to being relocated to the western Mediterranean in February 2005.

We have also purchased new manipulators and integrated them with Zeus to provide the capability for recording the X, Y and Z position of each artifact as it is recovered. This resulted in a more efficient and accurate site excavation. We have also integrated a new high-definition, or HD, camera system that has added HD filmmaking to our intellectual property and media capabilities.

Substantial additions to our computer control, navigation and guidance systems have also been integrated that significantly improve our capability for conducting pre-disturbance surveys and creating photomosaics. We have also added a new flotation pack that significantly increases the payload capabilities of ZEUS, enabling us to operate multiple tooling packages simultaneously.

During early 2005, we acquired a new side-scan sonar system which we believe will allow us to map the seafloor twice as fast as previous searches. Also, we entered into a charter agreement for a search vessel which we used during 2005 search operations and expect to use for continued search in our “Atlas” project area.

In the past we have from time to time disclosed information concerning each of our existing and planned search operations. In order to protect the identities of the targets of our planned search operations, we have decided to defer disclosing specific information relating to our search targets until we have located the targeted shipwreck or shipwrecks and determined a course of action to protect our property rights.

The SS Republic was a side-wheel steamer lost in deep water in 1865 after battling a hurricane for several days. The ship, en-route from New York to New Orleans, was reportedly carrying $400,000 in specie (1865 face value) when it sank. The ship’s history includes service in both the Confederate and Union navies during the American Civil War.

We discovered the shipwreck in the summer of 2003 nearly 1,700 feet below the surface of the Atlantic Ocean approximately 100 miles off the Georgia coast. In March 2004, Odyssey was awarded title and ownership to the SS Republic shipwreck and cargo, including the hull, artifacts and the specie on board when she sank.

Odyssey completed the pre-disturbance survey work on the SS Republic shipwreck site in October 2003. Over 4,600 digital still photographs were taken over the course of 23 dives. The detailed photomosaic produced a high-resolution image of the shipwreck site and debris field. This served as a map to help the Odyssey team determine excavation priorities and can be used in later study and documentation of the SS Republic. Shortly after commencement of archaeological excavation of the site, a substantial number of gold and silver coins were revealed using Odyssey’s Sediment Removal and Filtration, or SeRF, system.

In late 2003, when it appeared that all the coins might have been located in one small area, we anticipated recovering them all within 60 days. We recovered significantly more coins than were expected because many of them were smaller denomination silver half dollar coins. The coin recovery was efficient, allowing for recovery of up to 2,000 coins or more per day, even though they were picked up one at a time. The necessity of excavating the entire shipwreck site in an attempt to locate the balance of the coins, which our research suggests should still be there, required a significantly longer timeframe for the site excavation.

The archaeological excavation and recovery was completed in February 2005. During the SS Republic excavation, more than 51,000 gold and silver coins and approximately 14,000 artifacts were recovered. Our ROV ZEUS completed 262 dives to the shipwreck site and debris field, logging almost 3,500 hours of bottom time. The coins recovered to date represent approximately 25 percent of the “$400,000 in specie” (1865 face value) that historical research indicates was on board the Republic when she sank. We have been declared the owners of the wreck and there is a federal injunction in place preventing others from disturbing the site.

Coins recovered from the SS Republic have been divided into two categories. The first category, our “numismatic collection,” consists of coins that are indistinguishable from coins that have never been underwater. These have been priced to correlate with their numismatic value. The second category includes ungraded shipwreck coins (“shipwreck effect”) that have been conserved and encased in a certified tamper-resistant holder by Numismatic Conservation Services, or NCS, and Numismatic Guaranty Corporation, or NGC.

There are no Revenue Participation Certificates or revenue sharing arrangements related to the SS Republic recovery.

In April 2005, the Odyssey Explorer performed survey and archaeological work in the western Mediterranean. We located 23 shipwreck sites, produced 14 pre-disturbance photomosaics, and completed preliminary excavations on seven sites. The archaeological work resulted in the recovery of approximately 400 artifacts plus a substantial number of trading beads currently undergoing conservation and study by Odyssey’s research department.

On May 4, 2005, we announced that search operations had begun on our 2005 shipwreck search program, code-named the “Atlas” project, with our chartered side-scan survey vessel. The “Atlas” project is the result of an extensive target development program and consists of a minimum of five target shipwrecks. It is believed to be the most extensive shipwreck search operation ever launched. Utilizing our new, advanced side-scan system allowed us to map the seafloor twice as fast as previous searches we have conducted.

The Odyssey Explorer joined the Company’s chartered side-scan survey vessel in the “Atlas” search area in June 2005 to inspect promising side-scan targets utilizing the Remotely Operated Vehicle (ROV) ZEUS. Using one ship for survey and a second ship with an ROV for inspections resulted in a more efficient search process.

The 2005 “Atlas” search operations resulted in the mapping of over 4,600 square miles of the search area. Results include the discovery of 2,421 anomalies on the sea floor using our advanced high-resolution side-scan sonar system. After post-processing data, over 1,100 of those anomalies were selected for possible further examination. Of those, 577 sites have been inspected and at least 180 are believed to be manmade or shipwreck sites. Of the shipwrecks inspected by ZEUS, several exhibit key characteristics of some of the target shipwrecks being sought as part of the “Atlas” search project, but to-date we have not positively identified any of our primary targets. We are currently analyzing high-definition video, digital photos and collected artifacts to determine the potential identity, cultural significance, and economic value of the inspected sites.

On November 7, 2005, we announced that operations on the “Atlas” search project would be suspended through the winter months due to inclement weather while the Odyssey Explorer was deployed to the western Mediterranean to begin operations on the Sussex project. We intend to complete the search of the “Atlas” area in 2006 when the weather window re-opens. For reasons of security and strategic confidentiality, we do not disclose the location of the “Atlas” project area.

The Sussex project is an expedition to locate and recover artifacts and cargo of a large colonial-period British warship, HMS Sussex, which was lost in a severe storm in 1694. Based on documentary research conducted by contract researchers and our in-house research team in libraries and historical archives in Great Britain, France and other countries, we believe that there is a high probability the ship was carrying a cargo of coins with a substantial numismatic value. Our analysis of the data was accumulated from a review of ship’s logs, court martial records, state papers, treasury books and various other letters and reports. We conducted offshore search operations on this project in 1998, 1999, 2000 and 2001. Based on the results of these search operations, we believe there is a high probability we have located the remains of HMS Sussex.

On September 27, 2002, we entered into an agreement with the Government of the United Kingdom of Great Britain and Northern Ireland, which we refer to as Her Majesty’s Government (HMG), which allows us to conduct an archaeologically sensitive exploration of the shipwreck believed to be HMS Sussex and to recover artifacts from the shipwreck site. The agreement provided for us to submit a Project Plan to HMG concerning the equipment, personnel and methodologies we intend to use in the exploration of the shipwreck, and the conservation and documentation of any artifacts and cargo that may be recovered. This Plan was submitted and was declared fit for purpose during 2004 with the exception of the staffing plan, which could not be completed until the actual start date was agreed upon and the availability of personnel could be determined. The staffing plan was approved during 2005 and we began exploration of the site during December 2005.

In December 2005, our 251’ deep-ocean archaeological platform, the Odyssey Explorer, returned to the western Mediterranean from the “Atlas” search area. The ship and crew conducted the initial phases of Odyssey’s Sussex project plan previously approved by HMG.

During January 2006, we announced we had completed archaeological and environmental survey operations believed to fulfill the requirements of Phase 1A, and a substantial portion of Phase 1B, which included gathering archaeological evidence to identify the site believed to be HMS Sussex. A report was submitted to HMG, which detailed the work completed by Odyssey to satisfy Phase 1A requirements of the Sussex project plan. The report was reviewed by the Ministry of Defence (MoD) and the Sussex Archaeological Executive committee. HMG has notified Odyssey that the work detailed in the report met or exceeded all requirements of Phase 1A of the Sussex Project plan and Odyssey is authorized to proceed to complete Phase 1B of the project. A public version of the project plan is available at www.shipwreck.net.

Odyssey’s archaeological team has also completed a report detailing results of Phase 1B accomplished during the month of January, which was submitted to HMG in early March 2006.

A subsequent nota verbal was communicated to us through the same diplomatic channels on January 26, 2006, requesting that we suspend operations until the Junta of Andalucia appoints an expert to observe operations on the site believed to be the Sussex. It was further declared that the Junta did not appoint an expert because the Junta believed that Odyssey was working without appropriate authorization and that the Project Plan presented by us did not comply with the applicable Andalucian legislation as requested by the Spanish Ministry of Foreign Affairs.

When operating in territorial waters of any country, we have always done so with the appropriate authorizations. In the case of the Sussex project, because of regional sensitivities over the issue of the territorial status of the waters, and in accordance with diplomatic requests, our agreements of cooperation were made without prejudice to any jurisdictional claims relative to the territorial status of waters. Thus, the assertion of any claim to those waters or the assertion of any rights based on such claims, is not consistent with the diplomatic discussions relative to the project.

We did, in fact, submit a Project Plan to the Spanish Government through diplomatic channels that was believed to comply with all applicable requirements. In good faith, we began operations on the Sussex after submission of the Project Plan and subsequent assurance by the Spanish Government through diplomatic channels that failure of the Junta to appoint an expert to join the operation would not be considered a failure of Odyssey to comply with the cooperative agreement pursuant to the nota verbal. In addition, assurances were provided to us through diplomatic channels during January 2006 that there would be no interference with operations relating to the Sussex.

The January 2006 nota verbal from Spain appears to be a contradiction of that position, and we trust that the inconsistency has resulted from ambiguity and possible miscommunications relative to jurisdictional issues.

During meetings held in Spain in February 2006 with the Spanish Government, the Junta de Andalucia and the Government of the United Kingdom, we agreed to resubmit an archaeological project plan pursuant to specific requirements requested by Spanish authorities to move the project forward. This plan, which would include collaboration with Spanish archaeologists, is currently being prepared and we expect to deliver it to the appropriate authorities in March 2006.

We understand the geographic and political sensitivities surrounding this project and are willing to go to great efforts to show our willingness to work in a cooperative fashion with all governments involved. Both Odyssey and HMG have been assured by the Andalucian and Spanish central government authorities that they will expeditiously examine the archaeological project when it is re-submitted in order to allow Odyssey to proceed with the operation in a collaborative manner.

As a Sovereign warship, the HMS Sussex remains the property of the Government of the United Kingdom which has not been contested by the Spanish government or other entities to our knowledge. As part of the partnering agreement signed between Odyssey and HMG in 2002, the following sharing arrangements have been agreed upon with respect to the aggregate amount of the appraised values and/or selling prices of the artifacts, net of agreed selling expenses:

In addition to the percentages specified above, we will also pay the British Government 10% of any net income we derive from intellectual property rights associated with the project.

Also, we received the exclusive worldwide right to use the name “HMS Sussex” in connection with sales and marketing of merchandise (exclusive of artifacts) related to the shipwreck, and the British Government will receive 3 percent of the gross sales of such merchandise.

Our agreement with the British Government is for a period of 20 years, and can only be terminated if:

The shipwreck that we believe is the HMS Sussex is located in the search area for a project that we have previously referred to in the past as our “Cambridge” project. We sold through private placements of Revenue Participation Certificates, or RPCs, the right to share in our future revenues derived from the Cambridge Project. As of April 30, 1999, when the offering was closed, we had sold $825,000 of the RPCs. As a group, the holders are entitled to 100 percent of the first $825,000 of gross revenue, 24.75 percent of gross revenue from $4 million

to $35 million, and 12.375 percent of gross revenue above $35 million generated by the Cambridge Project. Additionally, on May 26, 1998, we signed an agreement with a subcontractor that entitled it to receive 5 percent of the post-finance cost proceeds from any shipwrecks in a certain search area of the Mediterranean Sea. The shipwreck we believe is the HMS Sussex is located within the specified search area, and we will be responsible to share future revenues, if any, from this shipwreck with the subcontractor. The subcontractor’s rights were foreclosed upon during 2002 and the purchaser was a limited liability company which was partially owned by two of our officers and directors. In order to remove any potential conflicts of interest, these two persons sold their interests in the limited liability company during 2005.

While working towards a resolution of issues relating to the Sussex project, the Odyssey Explorer has been deployed to other shipwreck sites in the Mediterranean as part of the our ongoing operational program to explore numerous other valuable shipwrecks throughout the world. Preliminary work has been conducted, including completion of photomosaics and surveys on two shipwreck sites. Our research indicates that one of the shipwrecks (code-named Bristol) contains a cargo of gold specie. We are currently analyzing the survey data from this preliminary work and preparing a recovery plan. It is anticipated that recovery on the Bristol project will be scheduled later in 2006 after the completion of other scheduled operations, including the Sussex and Atlas projects.

The Company’s other research vessel, the US flagged RV Odyssey, remains in Gibraltar to continue support of operations in that area.

The recovery of coins and artifacts from the SS Republic required us to create a marketing plan specifically to sell these coins and artifacts. Initially, silver coins were wholesaled to coin dealers who sold them through telemarketing and television outlets. During May 2004, we began to sell gold coins through the same dealer network. These dealers provided an immediate outlet for our coins and enabled us to generate revenue during 2004. While the coins sold well, it became apparent we were missing out on the opportunity to offer them additional products, such as books, replicas and artifacts, whether through Odyssey directly or through strategic partnerships.

During the ten months ended December 31, 2004, our primary customers for the sale of gold and silver coins were 13 independent coin dealers. Of these customers, four were responsible for sales volumes constituting 64 percent of total sales. These four coin dealers were Spectrum Numismatic, Monaco Financial, Silver Towne LP, and Kevin Lipton Rare Coins. During the twelve months ended December 31, 2005, we continued to sell gold and silver coins through our independent coin dealers. However, the number of independent dealers dropped from thirteen in 2004 to six in 2005 of which two dealers represented 56 percent of total sales. These two dealers were Monaco Financial and Spectrum Numismatic. Our experience has shown that many of these independent dealers are primarily interested in the higher quality numismatic coin market. As our availability of these higher quality coins diminishes, we expect the number of independent dealers interested in our coins to be reduced.

There are no contractual arrangements with any of our customers for future sales and we cannot forecast the demand, if any, these customers will have for our coins, artifacts or merchandise. No commissions are paid to dealers; however, our marketing representative is paid a commission on sales to coin dealers.

In December 2004, we opened a direct sales department to test distribution of our products through retail sales channels where gross margins would typically be higher. Sales in 2005 were less than projected. However, we are continuing to build a database of customers which we anticipate will buy additional Odyssey products from various shipwrecks. We believe sales volumes will increase as we continue to build our client base for repeat sales, expand our book sales, access leads generated by our attraction and other activities and increase advertising expenditures in direct response print, television and radio. Based on 2005 results, we have also been investigating additional resources and strategic partnerships to service direct response inquiries and orders.

We continue to develop additional indirect sales channels to supplement our coin dealer network for non-graded gold, shipwreck-effect silver coins and for other merchandise. While significant revenue has not yet been realized from these new indirect sales channels, we are building additional distribution channels for Odyssey shipwreck products, which should begin producing revenue in 2006.

The availability of raw materials is primarily dependent on the success of finding intrinsically valuable cargoes from shipwrecks (see Item 1A. Risk Factors). We recovered over 51,000 coins (approximately 4,000 $10 and $20 gold and 47,000 silver halves) and approximately 14,000 non-coin artifacts from the SS Republic. As of December 31, 2005, we have approximately 1,200 $10 and $20 gold coins and 39,000 silver halves remaining.

Many of the shipwrecks we intend to pursue may have important historical and cultural characteristics. Every such project undertaken will be subject to stringent archaeological standards, thus adding to the body of knowledge of the people, the history and culture of the vessel’s time. We believe adherence to these principles will increase the economic value of the artifacts and intellectual property rights of each project as well as enhance the level of cooperation we receive from governments, archaeological and other interests.

In addition, many deep-ocean recovery expeditions will lend themselves to interdisciplinary scientific studies including oceanography, marine biology, environmental research, bioengineering and other fields.

Odyssey works with a number of leading international maritime lawyers and policy experts to constantly monitor international legal initiatives that might affect our projects. As a matter of policy, we begin with the assumption that some entity, whether a government, private concern or insurance company, may have some rights to shipwrecks that are slated for search and recovery operations. Based on this assumption, rigorous legal tests are applied in order to ascertain which entities might be able to create roadblocks to a successful project. In some cases, such as that of HMS Sussex, it was determined that the most prudent mechanism for moving forward was to negotiate a contract with the owner of a vessel in order to manage litigation risk.

In other cases, such as the SS Republic project, we entered into an agreement whereby we purchased the insurance company’s interest in the shipwreck and cargo, opening the way for an immediate grant of title to Odyssey by the federal court that had jurisdiction.

To the extent that we engage in shipwreck search and recovery activities in the territorial, contiguous or exclusive economic zones of countries, Odyssey intends to comply with verifiable applicable regulations and treaties. Prior to beginning operations for any project, the legal and political aspects are carefully researched to ascertain what effect these issues may have on the potential success of the operation.

These factors are taken into account in determining whether to proceed with a project as planned. Other factors, such as the UNESCO Convention for the Protection of Underwater Cultural Heritage are also taken into consideration. New political initiatives such as this Convention could restrict access to historical shipwrecks throughout the world to the extent they might require compliance with cultural resource management guidelines and regulations. Some of these will require adherence to strict archaeological practices and we intend to follow reasonable guidelines in all projects to which they are applicable. Greg Stemm, Odyssey’s co-founder, was a member of the United States delegation that negotiated the UNESCO Convention, and as such provides us with a thorough understanding of the underlying principles and ramifications of the Convention, and advance notice of other cultural resource management issues that might affect our projects.

The UNESCO Convention is not expected to impact operations in international waters, and the United States, the United Kingdom and other major maritime governments have already stated explicitly that they do not

intend to sign the Convention. Nevertheless, some countries in whose waters we may work may sign the Convention. While the UNESCO Convention states that artifacts may not be sold, it also states that this prohibition may not prevent the provision of archaeological services, and we intend to provide such services in contracts with governments. We believe the primary value of the cargoes we seek are trade goods (such as coins, bullion and gems), which are not artifacts of historical, archaeological or cultural significance and such should not be subject to the rule prohibiting sale.

We believe there will be increased interest in the protection of underwater cultural heritage throughout the oceans of the world. We are uniquely qualified to provide governments and international agencies with resources to help manage these resources while providing the public with educational, scientific, historical and entertainment initiatives that originate from our shipwreck exploration activities.

There are a number of companies who publicly identify themselves as engaged in aspects of the shipwreck business, but they do not compete directly with us as an established deep-ocean archeological shipwreck exploration company. These entities include, but are not limited to, Subsea Resources Ltd. (a UK Company), Sovereign Exploration Associates International Inc. and Admirality Holding Company. Management currently believes only Subsea has the capital and managerial resources to compete directly with Odyssey in deep-ocean projects. It is possible that some currently unknown group may locate and recover a shipwreck on our project roster; however, due to the breadth of our historical and archival research, the already completed sonar and deep-water ROV inspection efforts, and the number of shipwreck projects in various stages of development, we do not believe that competition from one or more of these entities, known or unknown, would materially impact our operating plan or alter our current business strategy.

With the exception of vessel operations and conservation activities, our general business operations do not expose us to environmental risks or hazards. We carry insurance that provides a layer of protection in the event of an environmental exposure resulting from the operation of our vessels. The cost of such coverage is minimal on an annual basis. We believe the risk associated with our conservation activities is minimal.

As of December 31, 2005, we have 74 full-time employees working from our corporate offices in Tampa, Florida and Odyssey’s Shipwreck & Treasure Adventure in New Orleans, Louisiana. Additionally, we employ approximately 20 crewmen who operate the vessels RV Odyssey and Odyssey Explorer. We also hire technical personnel as needed for marine survey and recovery on the RV Odyssey, the Odyssey Explorer and our chartered search vessel. Depending upon the particular operations they are conducting, the RV Odyssey and our chartered search vessel will utilize two to four technicians, and the Odyssey Explorer will use from 14 to 20. In addition, we hire subcontractors and consultants from time to time to perform specific services.

Odyssey’s Forms 10-K, 10-Q, 8-K and all amendments to those reports are available without charge through Odyssey’s web site on the Internet as soon as reasonably practicable after they are electronically filed with, or furnished to, the Securities and Exchange Commission. They may be accessed as follows: www.shipwreck.net (SEC Filings Link).

One should carefully consider the following factors, in addition to the other information in this Annual Report on Form 10-K, in evaluating our company and our business. Our business, operations and financial condition are subject to various risks. Some of these risks are described below, and should be carefully considered in evaluating Odyssey or any investment decision relating to our securities. This section does not describe all risks applicable to Odyssey, its industry or its business. It is intended only as a summary of the principal risks.

An investment in Odyssey is extremely speculative and of exceptionally high risk. Although we have access to a substantial amount of research and data which has been compiled regarding various projects, the quality and reliability of such research and data is uncertain. Even if we are able to plan and obtain permits for our various projects, there is a possibility that the shipwrecks may have already been salvaged or may not be found, or may not have had anything valuable on board at the time of the sinking. Even if objects of value are located and recovered, there is the possibility that the cost of recovery exceeds the value of the objects recovered or that others, including both private parties and governmental entities, will assert conflicting claims and challenge our rights to the recovered objects. Finally, even if we are successful in locating and retrieving objects from a shipwreck and establishing good title to them, there are no assurances as to the value that such objects will bring at their sale, as the market for such objects is uncertain.

The success of a shipwreck project is dependent to a substantial degree upon the research and data we have obtained. By its very nature, research and data regarding shipwrecks is imprecise, incomplete and unreliable. It is often composed of or affected by numerous assumptions, rumors, legends, historical and scientific inaccuracies and inaccurate interpretations which have become a part of such research and data over time.

The availability of raw materials is primarily dependent on the success of finding intrinsically valuable cargoes from shipwrecks. If we are not successful in the exploration and recovery of shipwrecks, we would not have sufficient raw materials to sell.

Underwater recovery operations are inherently difficult and dangerous and may be delayed or suspended by weather, sea conditions or other natural hazards. Further, such operations may be undertaken more safely during certain months of the year than others. We cannot guarantee that we, or the entities we are affiliated with, will be able to conduct search and recovery operations only during favorable periods. In addition, even though sea conditions in a particular search location may be somewhat predictable, the possibility exists that unexpected conditions may occur and adversely affect our operations. It is also possible that natural hazards may prevent or significantly delay search and recovery operations or the ability to operate our themed attractions.

Persons and entities other than Odyssey and entities we are affiliated with (both private and governmental) may claim title to the shipwrecks. Even if we are successful in locating and recovering shipwrecks, we cannot assure we will be able to establish our right to property recovered against governmental entities, prior owners, or other attempted salvors claiming an interest therein. In such an event, we could spend a great deal of money and receive no revenue for our work.

Even if valuable items can be located and recovered, it is difficult to predict the price that might be realized for such items. The value of recovered items will fluctuate with the precious metals market, which has been highly volatile in past years. In addition, the entrance on the market of a large supply of similar items from shipwrecks located and recovered by others could depress the market.

We could experience delays in the disposition or sale of recovered objects.

The methods and channels that may be used in the disposition or sale of recovered items are uncertain at present and may include several alternatives. Ready access to buyers for any artifacts or other valuable items recovered cannot be assured. Delays in the disposition of such items could adversely affect our cash flow.

Legal, political or civil issues could interfere with our recovery operations.

Legal, political or civil initiatives of countries and/or major maritime governments could restrict access to shipwrecks or interfere with our search and recovery operations.

If we locate a shipwreck and assert a valid claim to items of value, there is a risk of theft of such items at sea, both before and after their recovery, by “pirates” or poachers and while in transit to a safe destination. Such thefts may not be adequately covered by insurance.

There are a number of competing entities engaged in various aspects of the shipwreck business, and in the future other competitors may emerge. One or more of these competing entities may locate and recover a shipwreck that we intend to locate and recover. In addition, these competing entities may be better capitalized and may have greater resources to devote to their pursuit of the shipwreck.

It is possible we will not be successful in obtaining title, or permission to excavate certain wrecks. In addition, permits that are sought for the projects may never be issued, and if issued, may not be legal or honored by the entities that issued them.

Profitability of our themed attractions segment may be adversely affected by a number of factors.

As we continue to develop and open themed attractions, there are several factors which could negatively affect our profitability including site selection, attendance projections, and economic activity. While we perform extensive market research on potential site locations, our attendance projections for those locations may not materialize in sufficient numbers to assure profitability. Also, a decline in national and/or regional economic conditions could reduce attendance and spending at our themed attractions. In addition, our themed attractions will compete against other forms of entertainment available in the area, and attendance may be subject to seasonal variations.

Changes in our business strategy or restructuring of our businesses may increase our costs or otherwise affect the profitability of our businesses.

As changes in our business environment occur we may need to adjust our business strategies to meet these changes or we may otherwise find it necessary to restructure our operations or particular businesses or assets.

When these changes or events occur, we may incur costs to change our business strategy and may need to write down the value of assets. In any of these events, our costs may increase, and we may have significant charges associated with the write-down of assets.

We depend on key employees and face competition in hiring and retaining qualified employees.

Our employees are vital to our success, and our key management and other employees are difficult to replace. We currently do not have employment contracts with our key employees. Further, we do not maintain key person life insurance on any of our employees. We may not be able to retain highly qualified employees in the future which could adversely affect our business.

Our articles of incorporation authorize the issuance of up to 10,000,000 shares of preferred stock. Our board of directors has the right to establish the terms, preference, rights and restrictions of the preferred stock. Such preferred stock could be issued with terms, rights, preferences and restrictions that could discourage other persons from attempting to acquire control and thereby insulate incumbent management. In certain circumstances, the existence of corporate devices that would inhibit or discourage takeover attempts could have a negative effect on the market value of our common stock.

The Company has received no written comments regarding its periodic or current reports from the staff of the Securities and Exchange Commission that were issued 180 days or more preceding the end of its 2005 fiscal year that remain unresolved.

We maintain our offices at 5215 W. Laurel Street, Tampa, Florida 33607. We purchased the 23,500 square foot two story office building in 2004 for $3,058,770 to serve as our corporate and operations headquarters. We currently lease approximately 25 percent of the space to a tenant. In April 2005, we entered into a three-year lease for a one story 8,100 square foot commercial building in proximity to our corporate headquarters which is utilized by our conservation department. In June 2005, we entered into a Lease Agreement with Jackson Brewery Millhouse, LLC, New Orleans, Louisiana, for the space where the Company opened its first interactive shipwreck and treasure attraction. The space is located in the Jax Brewery in the French Quarter of New Orleans. The lease covers approximately 8,651 square feet, has a five year term and a monthly rent of $17,571. Among other provisions the lease grants Odyssey the right to terminate the lease after 18 months for any reason without penalty.

On or about December 14, 2004 a complaint was filed against seven defendants including the Company in the Court of Common Pleas in the Ninth Judicial Circuit, County of Charleston, in the State of South Carolina. The complaint was filed by Republic & Eagle Associates, Inc. and Sea Miners, Inc. against John Morris, Greg Stemm, John Lawrence, John Balch, Daniel Bagley, Seahawk Deep Sea Technologies, Inc. (“Seahawk”) and the Company. The plaintiff’s allegations include breach of fiduciary duty, civil conspiracy and breach of contract based primarily upon an alleged contract(s) between the plaintiffs and Seahawk dated May 16, 1995 dealing with the search for the S.S. Republic. The plaintiffs allege that their research which was provided to Seahawk led to the discovery of the S.S. Republic and they seek an unspecified amount of damages and public recognition of their contribution. On February 18, 2005, John Morris, Greg Stemm, Daniel Bagley, and the Company filed their Notice of Motion and Motion to Dismiss Defendants John Morris, Greg Stemm, Daniel Bagley and Odyssey Marine Exploration, Inc. (the “Motion”). In the Motion, the defendants allege that the complaint should be

dismissed because, among other things, the South Carolina court does not have jurisdiction over them, the action was filed in an improper venue, plaintiffs lack the capacity to maintain the action, and the action should be barred based on the Doctrine of Forum Non Conveniens. The parties continue to engage in discovery. While the South Carolina court has not yet heard nor ruled on the Motion, we expect that a hearing will be held in April 2006 concerning our motion to dismiss the case based upon a lack of jurisdiction.

Management believes the lawsuit is without merit and intends to vigorously defend the action.

ITEM 5. MARKET FOR REGISTRANT’S COMMON EQUITY, RELATED STOCKHOLDER MATTERS AND ISSUER PURCHASES OF EQUITY SECURITIES

On November 19, 2003, our stock was listed on the American Stock Exchange and is traded under the symbol “OMR.” The following table sets forth the high and low sale prices for our securities during each quarter or interim reporting period for the periods set forth in the following schedule.

The number of record holders of our $.0001 par value Common Stock at February 28, 2006 was 302. This does not include shareholders that hold their stock in accounts in street name with broker/dealers.

Holders of the Common Stock are entitled to receive such dividends as may be declared by our Board of Directors. No dividends have been declared with respect to our Common or Preferred Stock and none are anticipated in the foreseeable future.

During the three months ended December 31, 2005, we issued 1,458,700 shares of our common stock to 33 investors who exercised warrants. The Company received a total of $3,646,750 in cash from these investors. The securities were issued pursuant to the exemption provided by Section 4(2) of the Securities Act of 1933. The purchasers of these securities are accredited investors who made an informed investment decision and had access to material information regarding the Company. The certificates representing the common shares bear an appropriate legend restricting the transfer of such securities, and stop transfer instructions have been provided to our transfer agent in accordance therewith. The shares of common stock issued in the warrant exercises have been registered in a Form S-3 registration statement under the Securities Act of 1933 for resale by the holders of the shares.

The following table sets forth selected financial data, which should be read in conjunction with the Company’s financial statements and the related notes to those statements included in “Item 8. Financial Statements and Supplementary Data” and with “Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations” appearing elsewhere in this Form 10-K. The selected financial data has been derived from the Company’s audited financial statements.

The following table includes fiscal years 2001, 2002 and 2003, which represent twelve-month periods ended February, 2002, 2003 and 2004, respectively. The fiscal year ended 2004 was a ten month transition period which ended December 31, 2004. For 2005, the fiscal year was a twelve month period which ended December 31, 2005.

2003 net income includes $5,762,103 income tax benefit which resulted due to elimination of valuation allowance against the deferred tax asset

2005 net income includes $3,281,510 income tax expense which resulted due to recording a valuation allowance against the deferred tax asset. The effect of recording the valuation allowance increased the net loss by $7,791,859.

ITEM 7. MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

The following discussion and analysis is intended to provide an investor with a narrative of our financial results and an evaluation of our financial condition and results of operations. The discussion should be read in conjunction with our consolidated financial statements and notes thereto. A description of our business is discussed in Item 1. of this report which contains an overview of our business as well as the status of our ongoing project operations.

The dollar values discussed in the following tables, except as otherwise indicated, are approximations to the nearest $100,000. For more detail refer to the Financial Statements and Supplemental Data in Item 8. The tables identify years 2005, 2004 and 2003. For 2005, the fiscal year included a twelve month period which ended December 31, 2005. Fiscal year 2004 included a ten month transition period which ended December 31, 2004. Fiscal year 2003 included a twelve-month period ended February 29, 2004.

Revenues are generated primarily through the sale of gold and silver coins, but also include other artifacts and merchandise. Revenues for fiscal years 2005 and 2004 were $10.0 million and $17.6 million, respectively,

representing sales volume of approximately 2,500 gold and silver coins in 2005 and approximately 9,000 gold and silver coins in 2004. In 2005 sales were made through independent coin dealers at wholesale prices as well as through our direct retail sales telemarketing area. In 2004, sales were made only through independent coin dealers. Revenues were significantly lower in 2005 versus 2004 due to a number of factors.

We continue to sell numismatic coins to independent coin dealers. During the latter half of 2005, we experienced a decrease in numismatic gold coin revenue, relative to 2004, due to a lower availability of our highest value gold coins, a desire to maximize total revenue from coin inventory, and sales to fewer independent coin dealers. The number of independent dealers dropped from thirteen in 2004 to six in 2005 of which two dealers represented 57 percent of our total sales. Our experience has shown that many of these independent dealers are primarily interested in the higher quality numismatic coin market. As our availability of these higher quality coins diminishes, we expect the number of independent dealers interested in our coins to be reduced. In addition, the sale of silver half dollars to our existing independent coin dealer wholesale channel was significantly reduced from 2004 levels, as their main interest has been in the numismatic gold coins. We are continuing to develop additional indirect sales channels to supplement our coin dealer network for our non-graded gold, shipwreck effect silver coins and for other merchandise. While significant revenue has not yet been realized from these new indirect sales channels, we are building additional distribution for Odyssey shipwreck products, which should begin producing revenue in 2006.

We continued to develop and plan to increase retail distribution of coins and other merchandise through direct sales channels. However, during our first year of direct sales in 2005, sales volumes were lower than originally expected. While we have been developing a strong client base with a promising percentage of repeat sales, it has taken longer than expected to generate the numbers of leads and customers necessary to reach our goals. We continue to investigate alternatives to expand and improve retail distribution of our products. We believe sales volumes will increase as we continue to build our client base for repeat sales expand our book sales, access leads generated by our attraction and other activities, and increase advertising expenditures for direct response print, television and radio marketing.

Cost of sales consists of shipwreck recovery costs, grading, conservation, packaging, and shipping costs associated with artifact, merchandise and book sales. Cost of sales as a percentage of revenue for 2005 and 2004 was 11 percent and 11 percent, respectively. The major factors that contribute to cost of sales as a percentage of revenue include capitalized ship recovery costs, number of artifacts recovered, revenue per artifact sold and the cost of merchandise and books. Cost of sales as a percentage of revenue will change depending on the sales mix because of the significantly higher unit sales prices for gold than silver coins and other merchandise.

Operations and research expenses were $11.3 million in 2005, compared to $2.0 million in 2004. Of the $9.3 million increase in 2005, $4.2 million was because vessel recovery costs were not capitalized since February 2005 when our recovery vessel left the SS Republic site. Vessel recovery costs of $4.8 million were capitalized in 2004 versus $0.6 million in 2005. Additionally, $3.3 million was attributable to vessel operations which included $1.8 million for chartering a vessel to conduct search operations for the Atlas project; $.5 million related to our research and conservation efforts; and $1.0 million was attributable to start up operations of our themed attractions segment, primarily due to the opening of our Odyssey Shipwreck & Treasure Adventure in New Orleans; and $0.3 million related to write-off of our investment in developing a second themed attraction location.

Marketing, general and administrative expenses were $9.3 million in 2005 as compared to $5.1 million in 2004. We continued expansion of our corporate support functions due to execution of our business plan primarily associated with continued development of our search and recovery projects, expansion of our marketing and sales function, and expansion of our corporate support functions. Of the $4.2 million increase, $2.3 million resulted from expansion of our marketing and sales function primarily associated with development of a direct sales

effort, $0.6 million related to general and administrative expenses associated with start up of our themed attractions segment, and $1.3 million was attributable to other general and administration expenses, corporate communication, information technology, professional and audit services primarily related to the implementation of Sarbanes-Oxley.

For fiscal year 2005, we recorded a provision for income taxes of $3.3 million compared to a provision for income taxes of $3.5 million for fiscal year 2004. Net operating loss carryforwards resulted in a $2.8 million net deferred tax asset as of December 31, 2004. Due to the uncertainty surrounding the realization of deferred tax assets resulting from operating loss carryforwards, we recorded a full valuation allowance of $7.8 million against the deferred tax assets as of December 31, 2005. The effect of this non-cash adjustment was to reduce the net deferred tax asset to $0 which resulted in a reduction of net income by $7.8 million. In accordance with SFAS No. 109, “Accounting for Income Taxes,” we have evaluated whether it is more likely than not that the deferred tax assets will be realized. Based on the available evidence, we have concluded that it is more likely than not that those assets would not be realizable without the recovery of high value shipwrecks (such as the Sussex) and thus a valuation allowance has been recorded as of December 31, 2005. We anticipate that we will continue to incur net losses in 2006. Our ability to generate net income in future periods is dependent upon the success of our ability to recover and monetize high-value shipwrecks. We were optimistic that our search and recovery efforts in 2005 would have been more successful than we have reported. However, we continue to be confident that we have several potential high-value shipwreck targets which could be recovered in 2006. Our current estimates do not include monetizing any assets for shipwrecks which may be recovered in 2006 or beyond. We will continue to reassess the need for a valuation allowance during each future reporting period.

At December 31, 2005, we had cash and cash equivalents of $3.3 million, an increase of $0.2 million from the December 31, 2004 balance of $3.1 million. Working capital and the ratio of current assets to current liabilities were $7.6 million and 3.9 to 1.0, respectively at December 31, 2005, compared with $8.4 million and 4.0 to 1.0, respectively, at December 31, 2004.

Net cash used in operating activities in 2005 was $11.0 million. Cash used in operating activities for 2005 primarily reflected an operating loss of $14.9 million, offset by deferred income taxes of $2.8 million, depreciation of $1.5 million, an increase in inventory and deposits and a decrease in accounts receivable. The net cash provided in operating activities for fiscal year 2004 primarily reflected positive operating results and deferred income taxes offset by an increase in inventory and accounts receivable.

Cash flows used in investing activities were $5.5 million and $4.1 million for fiscal years 2005 and 2004, respectively. Cash used in investing activities for 2005 primarily reflected $3.7 million for capital expenditures for our themed attractions segment including our New Orleans attraction, and $1.8 million used for the capital expenditures for property, equipment and improvements. Cash used in investing activities for fiscal year 2004 primarily reflected the cash purchase of our office building and improvements, property and equipment and capital expenditures related to attraction development.

Cash flows provided by financing activities were $16.7 million and $3.1 million for fiscal years 2005 and 2004, respectively. In 2005, the cash provided by financing activities included $16.8 million for the issuance of common stock which was primarily due to the exercise of outstanding warrants and common shares issued in our private placement, offset by $0.1 million mortgage repayment. Cash provided by financing activities of $3.1 million in fiscal year 2004 included the net proceeds from the sale of marketable securities of $2.0 million and $1.0 million from the proceeds of sale of common stock.

During March 2005, we received approximately $6.4 million from the sale of 2.7 million shares of common stock which was raised as part of a private placement net of commissions. The private placement consisted of 2,700,000 units which were sold to four accredited institutional investors at a price of $2.50 per unit. Each unit consisted of one share of common stock and a warrant to purchase one share of common stock at an exercise price of $3.50 per share during the two year period following the closing of the offering.

On April 21, 2005 we entered into a $6.0 million revolving credit facility with the Mercantile Bank. The credit facility replaces our prior credit facility with The Bank of Tampa. The line of credit is secured by $4.0 million of numismatic quality gold and 10,000 silver coins recovered from the SS Republic shipwreck. We intend to use the line of credit as a means to fund ongoing operations and equipment acquisitions as the need arises. We are presently in negotiations to restructure the Mercantile Bank credit facility to reduce the line of credit from $6.0 million to $3.0 million which would allow the existing collateralized gold coins to be released for sale and replaced with additional collateral of 5,000 silver coins.

During the latter half of 2005, approximately $9.0 million was received from the exercise of outstanding warrants which had an expiration date of October 5, 2005. The warrants were primarily issued as part of previous private placements and all were exercisable at a price of $2.50 per share.

The net proceeds from the private placement offering and warrant exercise was used to acquire additional equipment and technology to expand our search and recovery capabilities, to fund search and recovery operations, to fund themed attractions development and for general business purposes.

We held the grand opening of our first themed attraction, Odyssey’s Shipwreck & Treasure Adventure, on August 27, 2005, at the Jax Brewery complex in the French Quarter of New Orleans. The attraction was closed early on the grand opening day due to Hurricane Katrina. The Jax Brewery building in which the attraction resides remained closed until February 2006. On February 15, 2006, we re-opened Odyssey’s Shipwreck & Treasure Adventure in New Orleans. Unlike the rest of the city, the French Quarter escaped mostly intact and tourists are returning to the area. We are evaluating our business alternatives for a second attraction currently in development. We have approximately $469,000 remaining on our commitment to complete the second attraction. On November 1, 2005, we forfeited $50,000 by exercising our termination right for leased property relating to a potential themed attraction location and wrote off an additional $267,000 which the company had invested in the location.

On March 13, 2006, the Company sold 2,500,000 shares of non-voting Series D Convertible Preferred Stock, par value $0.0001 per share, at $3.50 per share to two institutional accredited investors pursuant to the terms of a purchase agreement. The Series D Preferred Stock is convertible into Common Stock at a ratio of one (1) share of Common Stock for every one (1) share of Series D Preferred Stock. Proceeds of the private offering were $8,750,000.

Based upon current expectations, we believe our cash and cash equivalents, cash generated from operations, bank credit facility and proceeds from recent equity offering will satisfy our working capital requirements for at least 2006. However, we anticipate we will continue to incur net losses in 2006. Our ability to generate net income in future periods is dependent upon the success of our ability to recover and monetize high-value shipwrecks. We were optimistic our search and recovery efforts in 2005 would have been more successful than we reported. However, we remain confident that we have several potential high-value shipwreck targets which could be recovered in 2006.

As of December 31, 2005, we have inventory of approximately 1,200 gold and 39,000 silver coins. Our sales estimates for 2006 include selling all our remaining gold coins and approximately a quarter of our remaining silver coins. Our current estimates do not include monetizing any assets for shipwrecks which may be recovered in 2006. We estimate our cash requirements for operations and capital expenditures over the next twelve months will range from $18 million to $20 million. We may be required to reduce budgeted expenses if sales estimates are not attained. Our cash requirements are only estimates and may change to suit our business and operational requirements in 2006. However, we cannot guarantee that the sales of our products and other available cash sources will generate sufficient cash flow to meet our overall cash requirements. If cash flow is not sufficient to meet our business requirements, we may be required to raise additional capital through other financing activities.

Revenues for the fiscal year 2004 were $17.6 million as compared to $0.1 million in fiscal year 2003. Sales of artifacts from the SS Republic began in May 2004. Revenues for fiscal year 2004 consisted primarily of artifact sales representing approximately 9,000 gold and silver coins primarily sold to independent coin dealers. Revenues for the fiscal year 2003 consisted of search operations performed for a third party and miscellaneous merchandise sales.

Cost of sales for fiscal year 2004 of $1.9 million consisted of shipwreck recovery costs, grading, conservation and packaging, and shipping costs associated with artifact sales. Cost of sales as a percentage of revenue for 2004 was 11 percent. The major factors that contributed to cost of sales as a percentage of revenue include capitalized ship recovery costs, number of artifacts recovered, and revenue per artifact sold. Artifact sales during 2004 consisted of both gold and silver coins. Cost of sales as a percentage of revenue will change depending on the sales mix because of the significantly different unit sales prices for gold and silver coins. In 2004, we experienced a higher dollar mix of gold coins.

Operations and research expenses for fiscal year 2004 were $2.0 million as compared to $2.6 million for fiscal year 2003. Our recovery vessel was purchased in August 2003 when deployment operations began. The decrease in 2004 was primarily due to increased capitalized ship recovery costs in 2004. Ship recovery costs were capitalized beginning in November 2003 associated with the discovery of artifacts on the SS Republic and continued through 2004 as recovery operations continued. Total operations and research costs before

capitalization were $6.0 million for fiscal year 2004 compared to $4.4 million for fiscal year 2003. The increase of $1.6 million before capitalization was primarily due to recovery operations for the vessel Odyssey Explorer during the period; additional archaeological, conservation, and research expenses; and search operations by the vessel RV Odyssey.

Marketing, general and administrative expenses for fiscal year 2004 were $5.0 million as compared to $2.6 million for the fiscal year 2003. The increase of $2.4 million resulted primarily from expansion of our corporate support functions due to execution of our business plan primarily associated with the recovery of the SS Republic artifacts. Of the $2.4 million increase, $1.7 million was the result of increased general and administrative expenses consisting primarily of personnel-related, insurance, depreciation and corporate communication expenses, and $0.7 million was due to the expansion of our marketing and sales function including attraction development costs, personnel-related expenses and selling commissions for artifacts.

For fiscal year 2004, we recorded a provision for income taxes of $3.5 million compared to a benefit for income taxes of $5.8 million for fiscal year 2003. Federal and state income taxes for 2004 have been provided for at an estimated annual effective rate of 37.6 percent. Net operating loss carryforwards resulted in a $2.8 million net deferred tax asset as of December 31, 2004.

At December 31, 2004, we had cash and cash equivalents of $3.1 million, an increase of $1.7 million from the February 29, 2004 balance of $1.4 million. Working capital as of December 31, 2004 was $8.4 million as indicated by current assets exceeding current liabilities. Of the net $1.7 million increase in cash for fiscal year 2004, $3.1 million was provided from financing and $2.8 million from operating activities which was offset by $4.1 million used for investing activities.

The increase in cash provided by operating activities for fiscal year 2004 versus the fiscal year 2003, was primarily due to improvements in operating results offset, in part, by changes in working capital. Cash provided from operating activities of $2.8 million for fiscal year 2004 consisted of $5.2 million of net income and non-cash expenses of $3.9 million primarily representing deferred income taxes and depreciation. Cash used in operating activities of $6.3 million represented net changes in balance sheet accounts primarily consisting of an increase in inventory costs and accounts receivable and an increase in accrued expense liabilities.

Cash used in investing activities for fiscal year 2004, of $4.1 million consisted of $2.2 million of capital expenditures for purchases of property and equipment primarily associated with our marine operations and corporate expansion efforts, $0.6 million for development of themed attractions, and $1.3 million for the

purchase of an existing office building and tenant improvements. A $2.0 million mortgage payable was entered into to provide the balance of the funds required for the purchase of the building. Approximately 75 percent of the building is being utilized as our corporate headquarters and 25 percent is currently leased.

In 2004, cash provided by financing activities of $3.1 million included $1.5 million short term borrowing against our credit facility offset by a loan repayment of $1.4 million, sales of marketable securities of $2.0 million and proceeds from a combination of warrants and stock options exercised for the issuance of common stock of $1.0 million.

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.

Under our bylaws and certain consulting and employment agreements, we have agreed to indemnify our officers and directors for certain events arising as a result of the officer’s or director’s serving in such capacity. The term of the indemnification agreement is as long as the officer or director remains in the employment of the company. The maximum potential amount of future payments we could be required to make under these indemnification agreements is unlimited. However, our director and officer liability insurance policy limits its exposure and enables us to recover a portion of any future amounts paid. As a result of our insurance policy coverage, we believe the estimated fair value of these indemnification agreements is minimal and no liabilities are recorded for these agreements as of December 31, 2005.

The discussion and analysis of our financial position and results of operations is based upon our financial statements, which have been prepared in accordance with accounting principles generally accepted in the U.S. The preparation of these financial statements requires us to make estimates and judgments that affect our financial position and results of operations. See Note A to the Financial Statements for a description of our significant accounting policies. Critical accounting estimates are defined as those that are reflective of significant judgment and uncertainties, and potentially result in materially different results under different assumptions and conditions. We have identified the following critical accounting estimates. We have discussed the development, selection and disclosure of these policies with our audit committee.

As of December 31, 2005, we had approximately $12.0 million of property and equipment and related assets. In accounting for these long-lived assets, we make estimates about the expected useful lives of the assets, the expected residual values of the assets, and the potential for impairment based on the fair value of the assets and the cash flows they generate. Our policy is to recognize impairment losses relating to long-lived assets in accordance with Financial Accounting Standards Board No. 144, “Accounting for the Impairment or Disposal of Long-Lived Assets” based on several factors, including, but not limited to, management’s plans for future operations, recent operating results and projected cash flows. To date no such impairment has been indicated.

In accordance with SFAS No. 109, “Accounting for Income Taxes,” we have evaluated whether it is more likely than not that the deferred tax assets will be realized. Based on the available evidence, we have concluded that it is more likely than not that those assets would not be realizable and thus a valuation allowance of $7.8 million has been recorded as of December 31, 2005. Our current estimates do not include monetizing any assets for shipwrecks which may be recovered in 2006 or beyond. We will continue to reassess the need for a valuation allowance during each future reporting period.

At December 31, 2005, the Company’s contractual obligations including estimated payments due by period, are as follows:

Long term debt represents the amount due on our existing mortgage for our office building. Operating leases consist primarily of our leases on our themed attraction in New Orleans and our conservation lab in Tampa. The purchase obligations in the table relate to contractual commitments to complete our second themed attraction.

Market risk is the exposure to loss resulting from changes in interest rates, foreign currency exchange rates, commodity prices and equity prices. We do not believe we have 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 9. CHANGES IN AND DISAGREEMENTS WITH ACCOUNTANTS ON ACCOUNTING AND FINANCIAL DISCLOSURE

2.	Exhibits
	The Exhibits listed in the Exhibit Index, which appears immediately following the signature page and is incorporated herein by reference, are filed as part of this Annual Report on Form 10-K.

The Company’s management is responsible for establishing and maintaining adequate internal control over financial reporting for the Company. With the participation of the Chief Executive Officer and the Chief Financial Officer, management conducted an evaluation of the effectiveness of internal control over financial reporting based on the framework and the criteria established in Internal Control – Integrated Framework, issued by the Committee of Sponsoring Organizations of the Treadway Commission. Based on this evaluation, management has concluded that internal control over financial reporting was effective as of December 31, 2005.

The Company’s independent auditor, Ferlita, Walsh & Gonzalez, P.A., a registered public accounting firm, has issued an attestation report on management’s assessment of internal control over financial reporting, which is included herein.

We have audited the accompanying consolidated balance sheets of Odyssey Marine Exploration, Inc. and subsidiaries as of December 31, 2005 and 2004, and the related consolidated statements of income, changes in stockholders’ equity and comprehensive income and cash flows for the fiscal year ended December 31, 2005, the ten month transition period ended December 31, 2004 and fiscal year ended February 29, 2004. These consolidated financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on these consolidated financial statements based on our audits.

We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the consolidated financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the consolidated financial statements. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion.

In our opinion, the consolidated financial statements referred to above present fairly, in all material respects, the financial position of Odyssey Marine Exploration, Inc. and Subsidiaries as of December 31, 2005 and 2004, and the results of their operations and their cash flows for the fiscal year ended December 31, 2005, the ten month transition period ended December 31, 2004 and fiscal year ended February 29, 2004, in conformity with U.S. generally accepted accounting principles.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the effectiveness of the Company’s internal control over financial reporting as of December 31, 2005, based on criteria established in Internal Control – Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO), and in our report dated February 14, 2006 expressed an unqualified opinion on management’s assessment of, and the effective operation of the internal control over financial reporting.

We have audited management’s assessment, included in the accompanying Management’s Annual Report on Internal Control over Financial Reporting, that Odyssey Marine Exploration, Inc. and Subsidiaries maintained effective internal control over financial reporting of December 31, 2005, based on criteria established in Internal Control – Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). Odyssey Marine Exploration, Inc. and Subsidiaries’ management is responsible for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting. Our responsibility is to express an opinion on management’s assessment and an opinion on the effectiveness of Odyssey Marine Exploration, Inc.’s internal control over financial reporting based on our audit.

We conducted our audit in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects. Our audit included obtaining an understanding of internal control over financial reporting, evaluating management’s assessment, testing and evaluating the design and operating effectiveness of internal control, and performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion.

A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use or disposition of the company’s assets that could have a material effect on the financial statements.

Because of inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that degree of compliance with the policies or procedures may deteriorate.

In our opinion, management’s assessment that Odyssey Marine Exploration, Inc and Subsidiaries maintained effective internal control over financial reporting as of December 31, 2005, is fairly stated, in all material respects, based on criteria established in Internal Control – Integrated Framework issued by COSO. Also, in our opinion, Odyssey Marine Exploration and Subsidiaries maintained, in all material respects, effective internal control over financial reporting as of December 31, 2005, based on criteria established in Internal Control – Integrated Framework issued by COSO.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the consolidated balance sheets of Odyssey Marine Exploration and Subsidiaries as of December 31, 2005 and 2004, and the related consolidated statements of income, changes in stockholders’ equity and comprehensive income, and cash flows for the fiscal year ended December 31, 2005, the ten month transition period ended December 31, 2004 and fiscal year ended February 29, 2004, and our report dated February 14, 2006 expressed an unqualified opinion on those consolidated financial statements.

During the quarter ended March 31, 2005, warrants to purchase a total of 470,000 shares were issued to two persons associated with the placement agent as part of the commission paid in connection with a private placement of securities during the period. These warrants are exercisable at a price of $3.50 per share for a period of two years. The fair value of these warrants as computed by the Black-Scholes option pricing model was $.72 per warrant, or $336,504. Due to the high volatility of our stock, we do not believe that the Black-Scholes model provides a realistic fair value for the warrants. These warrants do not have the characteristics of traded warrants, therefore, the warrant valuation models do not necessarily provide a reliable measure of the fair value. By agreement between the parties at the time of the offering, the Company used a fair value of $.50 per warrant, or $235,000.

The ending balance in Attraction development on December 31, 2004 for our New Orleans Attraction development in the amount of $196,054 has been transferred to Property and equipment for the period ended December 31, 2005.

We previously reported $1,888,742 in Attraction development purchases for the six month period ended June 30, 2005. This amount has been moved to Purchase of property and equipment for the fiscal year ended December 31, 2005.

Odyssey Marine Exploration, Inc., is engaged in the archaeologically sensitive exploration and recovery of deep-water shipwrecks throughout the world and the operation of interactive attractions and exhibits which will entertain and educate multi-generational audiences, and present our unique shipwreck stories and artifacts. The corporate headquarters are located in Tampa, Florida.

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.

The consolidated financial statements include the accounts of the Company and its wholly owned subsidiaries, Odyssey Marine, Inc., Odyssey Marine Services, Inc., OVH, Inc., Odyssey Retriever, Inc. and Odyssey Marine Entertainment, Inc. All significant inter-company transactions and balances have been eliminated.

Shipwreck Heritage Press, LLC was created during 2005 to publish and distribute print media. The entity does not have activity and has not been capitalized, and therefore, it is not consolidated.

Certain operating expense amounts for the fiscal years ended February 29, 2004 and December 31, 2004 have been reclassified to conform to the presentation of the December 31, 2005 amounts. The reclassifications have no effect on net income for the fiscal years ended February 29, 2004 and December 31, 2004.

Management uses 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.

Advertising costs are expensed as incurred. Advertising expense for the fiscal years 2005, 2004, and 2003 was $996,000, $45,000, and $4,500, respectively.

Revenue from sales is recognized at the point of sale when legal title transfers. Legal title transfers when product is shipped or is available for shipment to customers. Bad debts are recorded as identified and no allowance for bad debts has been recorded. A return allowance is established for merchandise sales which have a right of return. Accounts receivable is stated net of any recorded allowance for returns.

Cash and cash equivalents 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.

The carrying value of cash and cash equivalents, accounts receivable, prepaid expense, investments, accounts payable, accrued expense, loan payable and mortgage payable approximate fair value. Considerable judgment is necessarily required in interpreting market data to develop the estimates of fair value, and, accordingly, the estimates are not necessarily indicative of the amounts that we could realize in a current market exchange.

Our inventory consists of artifacts recovered from the SS Republic shipwreck, related packaging material for the artifacts, and merchandise.

The SS Republic shipwreck artifacts are recorded in inventory at the costs of recovery and conservation. The recovery costs also include the fee paid to an insurer to relinquish the insurers claim to the artifacts recovered and the shipwreck. We started capitalizing costs in November 2003 after establishing the artifacts being recovered had a net realizable value exceeding the costs being capitalized. We continued to capitalize the recovery costs until the shipwreck site was completely excavated. The capitalized costs include direct costs of recovery such as vessel and related equipment operations and maintenance, crew and technical labor, fuel, provisions and supplies, port fees and depreciation. Conservation costs include fees paid to conservators for cleaning and preparing the artifacts for sale. We continually monitor the recorded aggregate costs of the artifacts in inventory to ensure these costs do not exceed the net realizable value. We use historical sales, publications or available public market data to assess market value.

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

Our policy is to recognize impairment losses relating to long-lived assets in accordance with Financial Accounting Standards Board No. 144, “Accounting for the Impairment or Disposal of Long-Lived Assets” based on several factors, including, but not limited to, management’s plans for future operations, recent operating results and projected cash flows. To date, no such impairment has been indicated.

United States Treasury bills owned by us during the year ending December, 31 2005, were deemed available-for-sale and carried at fair value. Unrealized gains and losses on these securities were excluded from earnings and reported, net of any income tax effect, as a separate component of stockholders’ equity. At December 31, 2005, we did not own any United States Treasury Bills.

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 is normally between five and ten years. Leasehold

improvements are amortized over their estimated useful lives or the lease term, if shorter. Depreciation directly related to the recovery of the SS Republic cargo has been capitalized as inventory. Depreciation expense capitalized was directly related to our vessel Odyssey Explorer and supporting equipment during the SS Republic excavation.

Basic earnings per share (EPS) is computed by dividing income available to common shareholders by the weighted-average number of common shares outstanding for the period. 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. Incurring a net loss during the period ended December 31, 2005 causes the potential common shares to have an anti-dilutive effect for the period and therefore such shares are excluded from the EPS calculation as identified in the below table. For the fiscal years ended December 31, 2004 and February 29, 2004, all other exercisable stock options and stock warrants were excluded from the computation of diluted EPS because the options exercise prices were greater than the average market price of the common shares and would have had an anti-dilutive effect if included in the computation.

At December 31, 2005 potential common shares, calculated using the treasury stock method, for the fiscal year ended December 31, 2005, the ten month transition period ended December 31, 2004 and the fiscal year ended February 29, 2004, were included in the computation of diluted EPS as follows:

Potential common shares were also excluded from the calculation of diluted earnings per share because the effect of including the potential shares in the computation would have been anti-dilutive as follows:

The following is a reconciliation of the numerators and denominators used in computing basic and diluted net income per share:

We account for stock-based compensation using the intrinsic value method in accordance with Accounting Principles Board Opinion No. 25, “Accounting for Stock Issued to Employees,” and have adopted the disclosure provisions of Statement of Financial Accounting Standards No. 148, “Accounting for Stock-Based Compensation – Transition and Disclosure, an amendment of FASB Statement No. 123.” Under APB No. 25, when the exercise price of our employee stock options equals or exceeds the market price of the underlying stock on the date of grant, no compensation expense is recognized. Accordingly, no compensation expense has been recognized in the consolidated financial statements in connection with employee stock option grants.

The following table illustrates the effect on net income and earnings per share had we applied the fair value recognition provisions of Statement of Financial Accounting Standards No. 123, “Accounting for Stock-Based Compensation,” to stock-based employee compensation.

The weighted average estimated fair value of stock options granted during the fiscal year ended December 31, 2005, the ten month transition period ended December 31, 2004 and the fiscal year ended February 29, 2004 were $2.10, $3.78 and $1.21 respectively. These amounts were 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 assumptions used in the Black-Scholes model were as follows for stock options granted in the year ended December 31, 2005, ten month period ended December 31, 2004 and year ended February 29, 2004:

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 these assumptions can materially affect the fair value of the options. Our options do not have the characteristics of traded options, therefore, the option valuation models do not necessarily provide a reliable measure of the fair value of our options.

On September 20, 2005, our Board of Directors approved the immediate vesting of unvested and “underwater” stock options to purchase 215,000 shares of common stock previously granted to employees and officers under Odyssey’s 1997 Employee Stock Option Plan with exercise prices of $5.00 per share. The exercise price of the options was not changed. The primary purpose of the accelerated vesting of these “out of the money” options was to reduce the Company’s future reportable compensation expense upon the adoption of Statement of Financial Accounting Standards (SFAS) No. 123(R), “Share Based Payment,” effective for our fiscal year beginning January 1, 2006. The valuation for the accelerated options has been included herein. By taking this approach, we expect to eliminate a charge to our income statement of approximately $680,000 during 2006 and $40,000 in 2007. As a result of the issuance of a revision of FASB SFAS No. 123, Accounting for Stock-Based Compensation , we will be required, beginning in the first quarter of 2006, to begin expensing the stock compensation related to options instead of the disclosure only requirement disclosed above.

Equity instruments issued, if any, to non-employees in exchange for goods, fees and services are accounted for under the fair value-based method of SFAS No. 123.

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 all of the deferred tax asset will not be realized. (See NOTE R)

We maintain our cash in five financial institutions. The Federal Deposit Insurance Corporation insures up to $100,000 per account. At December 31, 2005 our uninsured cash balance was approximately $2,789,000.

Cash and cash equivalents include cash on hand and United States Treasury Bills maturing in less than ninety days from the date of purchase. At December 31, 2005, we did not own any United States Treasury Bills.

Accounts receivable consists of trade accounts receivable resulting from customer sales of artifacts and merchandise. The balances at December 31, 2005 and 2004 are $1,527,913 and $2,104,914, respectively. The balance at December 31, 2005 is net of a publishing return reserve amount of $127,398.

SS Republic recovery operations continued until February 2005. Based on our estimates of the timing of future sales, $5,839,914 and $5,945,177 of artifact inventory for the fiscal years ended 2005 and 2004 were classified as non-current.

The recorded amount of the SS Republic artifacts represents the accumulated capitalized costs of recovery and conservation of these items as follows:

For the period ended December 31, 2005, prepaid expenses consist of $333,866 of prepaid insurance premiums and $234,012 of other operating prepaid costs. For the period ended December 31, 2004, prepaid expenses consist of $304,276 of prepaid insurance premiums and $108,592 of other prepaid operating costs. All prepaid expenses are amortized on a straight-line basis over the term of the underlying agreements. Deposits are held by various vendors for equipment, services, and in accordance with agreements in the normal course of business.

Attraction development balances of $1,172,475 and $569,634 for the periods ended December 31, 2005 and 2004, respectively, represent direct costs for project engineering and design costs and fabrication/construction costs for attraction exhibits in process of completion. During the current year, we transferred $2,556,827 to Property and equipment upon the opening of our New Orleans exhibit. The $1,172,475 remaining at the end of the current year relates to the in-process construction of our second exhibit. For further discussion see “Note U – Commitments and Contingencies”.

On July 23, 2004, we purchased a 23,500 square foot two story office building for $3,058,770 to serve as our corporate and operations headquarters. With tenant improvements the facility is recorded on the books at a cost of $3,470,523. We currently lease approximately 25% of the space to a tenant.

The artifact balances for both reportable years consist of artifacts conserved specifically for the company and are not for resale. Deposits include $432,500 on account with the United Kingdom’s Ministry of Defense relating to the expense deposits for the HMS Sussex as well as a $100,000 deposit to fund conservation and documentation of any artifacts recovered. These deposits are refundable from proceeds the United Kingdom would receive if the HMS Sussex is discovered and its artifacts monetized. If the HMS Sussex is not discovered, the Company is at risk for the entire amounts. Other deposits are held by various vendors for equipment, services, and in accordance with agreements in the normal course of business. Image use rights are amounts paid to utilize, for a period up to five years, copyrighted images in our themed attractions segment. The amount is net of $1,326 of amortization.

On July 23, 2004, we entered into a mortgage loan for $2,000,000 with the Bank of Tampa for the purchase of our corporate office building. The mortgage loan is due in 10 years and monthly payments are based on a 20 year amortization schedule. Interest, initially at 4.94%, will be adjustable semiannually based upon changes in the LIBOR (London Interbank Offered Rate) index. The interest rate at December 31, 2005 was 6.71%. Interest expense was $119,833 for the period ended December 31, 2005 and $41,630 for the ten months ended December 31, 2004.

Maturities of long-term debt associated with the mortgage payable are as follows:

See “Note U – Commitments and contingencies” for information pertaining to consolidated commitments.

On April 21, 2005, we entered into a $6 million revolving credit facility from the Mercantile Bank (the “Bank”). The credit facility replaces the Company’s prior credit facility with The Bank of Tampa. The credit facility has a floating interest rate equal to the “LIBOR 30-Day Index Rate” plus two hundred sixty-five basis points (2.65%), requires monthly payments of interest only and is due in full on April 21, 2008. The interest rate at December 31, 2005 was 6.94%. The Company is also required to pay the Bank an unused line fee equal to 0.25% per annum of the unused portion of the credit line, payable quarterly. The line of credit is secured by $4 million of numismatic quality gold coins and 10,000 silver coins recovered by the Company from the SS Republic shipwreck. The Company’s custodian will hold the coins used as collateral until released by the Bank.

Additionally, the Company granted a first lien position on all corporate assets, including a provision not to pledge as collateral our Company-owned vessels. The Company is required to comply with a number of covenants including maintaining a minimum stockholders’ equity of $20,000,000, which amount may be increased after the first year. At December 31, 2005, the loan balance was $11,433.

See “Note U – Commitments and contingencies” for information pertaining to consolidated commitments.

Vessel operations relates to expenditures required to operate our ships such as fuel, repair and maintenance and port fees. Other operating expenses contain general costs related to, but not limited to marketing, book distribution fees, professional services and the attraction and exhibits.

On December 9, 2002, a Georgia limited liability company acquired rights from an unrelated third party through a foreclosure sale to receive 5% of post finance cost proceeds, if any, from shipwrecks that we may recover within a predefined search area of the Mediterranean Sea. The shipwreck we believe to be HMS Sussex is located within this search area. Two of our officers and directors owned a 60% interest in the limited liability company until they sold their interests to an unrelated third party in 2005. In the event that political interference precludes the recovery efforts of the project, the officers would be required to buy back their interests.

A construction company, owned by the stepson of an officer of the company, was paid for renovation services on our corporate headquarters building amounting to $105,259 and $243,800 for the periods ended December 31, 2005 and 2004, respectively. Also, the spouse of a Company officer performed logo design services for the period ended December 31, 2005 amounting to $3,525.

We have sold through private placements of Revenue Participation Certificates (“RPCs”) the right to share in our future revenues derived from the Cambridge project which refers to the 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.

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.

As of April 30, 1999, when the offering was closed, we had sold $825,000 of a maximum of $900,000 of the Cambridge RPCs. As a group, the 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 Cambridge project.

Distributions are to be made to each certificate holder within 15 days from the end of each quarterly reporting period in which we receive any cash proceeds from, or as a result of, the Cambridge Project. The Cambridge RPC units constitute restricted securities.

In a private placement, which closed in September 2000, we sold “units” comprised 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.

When the offering was closed, in September 2000, a total of five $50,000 units consisting of one Republic RPC and 100,000 shares of Common Stock had been sold, and the cost of each unit was allocated as $37,500 for the stock and $12,500 for the RPC. Therefore, a total of $62,500 was reflected on the books as deferred income from the sale of Republic Revenue Participation Certificates.

As of December 31, 2005 we had sold, in total, $887,500 of RPCs, which are reflected on the books as Deferred RPC Income to be amortized under the units of revenue method once management can reasonably estimate potential revenue for these projects.

These RPC issues 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.

We currently have 9,300,000 shares of Preferred Stock and 510,000 shares of Series A Convertible Preferred Stock that have been authorized and none outstanding. The Preferred Stock may be issued in series from time to time with such rights, designations, preferences and limitation as our Board of Directors may determine by resolution.

On September 18, 2002, we established a series of Preferred Stock known as “Series C Convertible Preferred Stock”(“Series C Preferred Stock”), having a par value of $.0001 per share and an authorization of one (1) share. One share of Series C Convertible Preferred Stock was issued for $500,000 in cash.

On August 19, 2003 the share of Series C Convertible Preferred Stock was converted into 400,000 shares of our Common Stock and warrants to purchase 400,000 shares of our Common Stock at an exercise price of $2.50 per share.

The converted share was then restored to the status of authorized but un-issued shares of Preferred Stock of the Corporation, without designation as to series, and may thereafter be issued.

We adopted the 1997 Stock Option Plan on September 8, 1997. Under the terms of the plan, non-statutory options to purchase Common Stock are granted to employees, consultants and non-employee directors at not less than 100% of the fair market value of the shares on the date of grant or the par value thereof whichever is greater. Options currently expire no later than 5 years from the date of grant and are fully vested in two years or less. The cumulative number of shares which may be subject to options issued and outstanding pursuant to the plan is limited to 3,500,000 shares. Additional information with respect to the plan’s stock option activity is as follows:

On August 3, 2005, our Board of Directors approved and adopted our 2005 Stock Incentive Plan. This plan will be submitted to our shareholders at the Annual Meeting of Stockholders on May 5, 2005. The plan provides for the grant of incentive stock options, non-qualified stock options, restricted stock awards, restricted stock units and stock appreciation rights. We have reserved 2,500,000 of our authorized but unissued shares of common stock for issuance under the plan and not more than 500,000 of these shares may be used for restricted stock awards and restricted stock units. Any incentive option and any 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 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.

The following table summarizes information about stock options outstanding at December 31, 2005:

At December 31, 2004, we had 3,950,000 warrants outstanding. These warrants were issued to one individual in connection with loans made to us, to one consultant for services, to ten individuals in connection with the conversion of loans into common stock, and to 52 individuals who purchased units in a private placement offering.

During the fiscal year ended December 31, 2005, all of the warrants outstanding at December 31, 2004 were exercised. Proceeds of $9,869,750 were realized from the exercise of these warrants.

During March of 2005, we issued 3,170,000 warrants to six entities in a private placement offering. During the quarter ended September 30, 2005 we issued 100,000 warrants to a vendor for services relating to a marketing program. Warrants outstanding at December 31, 2005 are as follows:

During August 2003, an individual was issued 25,000 shares of restricted common stock and a warrant for the purchase of 25,000 shares of restricted common stock at $2.50 per share, in exchange for data related to the SS Republic project. The data purchased was recorded as an operating expense in the amount of $31,250.

As of December 31, 2005, we had consolidated income tax net operating loss (“NOL”) carryforwards for federal income tax purposes of approximately $30,551,000 and for state income tax purposes of approximately $25,080,000. The federal and state NOL carryforwards will expire in various years ending through the year 2025.

The components of the provision for income taxes (benefits) are attributable to continuing operations as follows:

Deferred income taxes reflect the net tax effects of the temporary differences between the carrying amounts of assets and liabilities for financial reporting purposes and the amounts used for income tax purposes. Significant components of the Company’s deferred tax assets and liabilities are as follows:

As reflected above, we have recorded a net deferred tax asset of $0 at December 31, 2005. In accordance with SFAS No. 109, “Accounting for Income Taxes,” we have evaluated whether it is more likely than not that the deferred tax assets will be realized. Based on the available evidence, we have concluded that it is more likely than not that those assets would not be realizable without the recovery of high value shipwrecks (such as the Sussex) and thus a valuation allowance has been recorded as of December 31, 2005. We anticipate that we will continue to incur net losses in 2006. Our ability to generate net income in future periods is dependent upon the success of our ability to recover and monetize high-value shipwrecks. We were optimistic that our search and recovery efforts in 2005 would have been more successful than we have reported. However, we continue to be confident that we have several potential high-value shipwreck targets which could be recovered in 2006. Our current estimates do not include monetizing any assets for shipwrecks which may be recovered in 2006 or beyond. We will continue to reassess the need for a valuation allowance during each future reporting period.

Income taxes for the twelve month period ended December 31, 2005, ten month period ended December 31, 2004 and twelve month period ended February 29, 2004 differ from the amounts computed by applying the effective income tax rate of 34.0% to income taxes as a result of the following:

During the twelve month period ended December 31, 2005 and ten month period ending December 31, 2004, we recognized certain tax benefits related to stock option plans in the amount of $453,110 and $252,836, respectively. Such benefits were recorded as an increase in the deferred tax asset and an increase in additional paid-in capital.

During the fiscal year ended December 31, 2005, we had two customers who accounted for 45.7% and 10.4% of our total sales. For the fiscal year ended December 31, 2004 we had four customers who accounted for 12.5%, 14.4%, 13.9%, and 23.0% of our total sales.

SFAS 131, Disclosures about Segments of an Enterprise and Related information, establishes standards for reporting information about operating segments. Operating segments are defined as components of an enterprise about which separate financial information is available that is evaluated regularly by the chief operating decision maker in deciding how to allocate resources and in assessing performance. Our chief operating decision maker is our Chief Executive Officer. The Company manages and evaluates the operating results of the business in two primary segments, shipwreck exploration and themed attractions. Because of the expansion of our themed attractions, we began reporting segment information for the three and nine months ended September 30, 2005.

Shipwreck Exploration – This segment includes all operating activities for exploration and recovery of deep-water shipwrecks including the marketing, promotion and distribution of recovered artifacts, related replicas, merchandise and books through various retail and wholesale sales channels.

Themed Attractions – This segment is responsible for the development and operation of interactive attractions and exhibits which will entertain and educate multi-generational audiences, and present our unique shipwreck stories and artifacts.

The accounting policies of the business segments are the same as those described in the summary of significant accounting policies included in Note A. Management evaluates the operating results of each of its

reportable segments based upon revenues and operating income (loss) before taxes. Corporate overhead supporting segments including legal, finance, human resources, information technology, real estate facilities, as well as stock based compensation is included within the shipwreck exploration segment and not allocated to themed attractions.

We have sold the rights to share in future revenues, if any, with respect to the Seattle (formerly Republic) and Cambridge projects and have recorded $887,500 as Deferred Income From Revenue Participation Certificates (See NOTE O). We are contingently liable to share the future revenue of these projects only if revenue is derived from these specific projects.

To date, the only income derived from these projects resulted in a one time revenue distribution payment of $12,986 to the holders of the Cambridge RPC’s.

Revenue from the SS Republic shipwreck or its cargo are not subject to revenue sharing.

In addition, on May 26, 1998, we signed an agreement with a subcontractor that entitled it to receive 5% of the post finance cost proceeds from any shipwrecks in a predefined search area of the Mediterranean Sea. A shipwreck we have found, which we believe to be the HMS Sussex, is located within the specified search area and we will be responsible to share future revenues, if any, from this shipwreck. On December 9, 2002, a Georgia limited liability company acquired the 5% interest from the subcontractor through a foreclosure sale. (See NOTE N)

On or about December 14, 2004 a complaint was filed against seven defendants including the Company in the Court of Common Pleas in the Ninth Judicial Circuit, County of Charleston, in the State of South Carolina. The complaint was filed by Republic & Eagle Associates, Inc. and Sea Miners, Inc. against John Morris, Greg Stemm, John Lawrence, John Balch, Daniel Bagley, Seahawk Deep Sea Technologies, Inc.(“Seahawk”) and the Company. The plaintiff’s allegations include breach of fiduciary duty, civil conspiracy and breach of contract based primarily upon an alleged contract(s) between the plaintiff’s and Seahawk dated May 16, 1995 dealing with the search for the S.S. Republic. The plaintiff’s allege that their research which was provided to Seahawk led to the discovery of the S.S. Republic and they seek an unspecified amount of damages and public recognition of their contribution. On February 18, 2005, John Morris, Greg Stemm, Daniel Bagley, and the Company filed their Notice of Motion and Motion to Dismiss Defendants John Morris, Greg Stemm, Daniel Bagley and Odyssey Marine Exploration, Inc. (the “Motion”). In the Motion, the defendants allege that the complaint should be dismissed because, among other things, the South Carolina court does not have jurisdiction over them, the

action was filed in an improper venue, plaintiffs lack the capacity to maintain the action, and the action should be barred based on the Doctrine of Forum Non Conveniens. The parties continue to engage in discovery. While the South Carolina court has not yet heard nor ruled on the Motion, we expect that a hearing will be held in April 2006 concerning our motion to dismiss the case based upon a lack of jurisdiction. Management believes the lawsuit is without merit and intends to vigorously defend the action.

The Company may be subject to a variety of claims and suits that arise from time to time in the ordinary course of business. Management currently believes that these claims and suits will not have a material adverse impact on its financial position or its results of operations.

On September 27, 2002, we entered into an agreement (the “Agreement”) with the Government of the United Kingdom of Great Britain and Northern Ireland (the “British Government”). The Agreement allows us to conduct an archaeologically sensitive exploration of the shipwreck believed to be HMS Sussex and to recover artifacts and cargoes from the wreck site.

The Agreement required us to submit a Project Plan (the “Plan”) to the British Government concerning the equipment, personnel and methodologies we intend to use in the exploration of the shipwreck, and the conservation and documentation of any artifacts and cargo that may be recovered. We submitted our Plan to the government on November 11, 2002, and received approval on May 22, 2003.

We have paid a 5,000 pounds (approximately $7,845) refundable license fee and an expense deposit of 250,000 pounds ($432,500) for the British Government’s expenses in connection with the project. The deposit is not refundable if the project is not successful. At such time as we represent to the British Government that we have recovered $3.5 million worth of cargo and/or artifacts, all funds advanced for the British Government’s expenses will be returned to us. We were also required to fund a $100,000 deposit to ensure that funds are available for the conservation and documentation of any artifacts recovered. The Agreement provides a mechanism for raising or lowering the deposit amount depending upon the quantity and condition of the artifacts that need to be conserved and documented.

The following sharing arrangements have been agreed upon with respect to the aggregate amount of the appraised values and/or selling prices of the artifacts, net of agreed selling expenses:

In addition to the percentages specified above, we will also pay the British Government 10% of any net income we derive from intellectual property rights associated with the project.

We also received the exclusive worldwide right to use the name “HMS Sussex” in connection with sales and marketing of merchandise (exclusive of artifacts) related to the wreck, and the British Government will receive 3% of the gross sales of such merchandise.

The Agreement is for a period of 20 years, and may only be terminated if the shipwreck is not the HMS Sussex or if we are in serious breach of our obligations under the Agreement.

At December 31, 2005, the Company’s future contractual obligations are as follows:

Long term debt represents amount due on our existing mortgage for our office building. Operating leases consist primarily of our leases on our themed attraction in New Orleans and our conservation lab in Tampa. The purchase obligations in the table relate to contractual commitments to complete our second themed attraction.

See “Note K – Mortgage payable” and “Note L – Loan payable” for related information.

Based upon current expectations, we believe our cash and cash equivalents, cash generated from operations, and bank credit facility, will allow us to continue as a going concern during 2006. However, we anticipate we will continue to incur net losses in 2006. Our ability to generate net income in future periods is dependent upon the success of our ability to recover and monetize high value shipwrecks. We were optimistic our search and recovery efforts in 2005 would have been more successful than we have reported. However, we continue to be confident we have several potential high-value shipwreck targets which could be recovered in 2006.

As of December 31, 2005, we have inventory of approximately 1,200 gold and 39,000 silver coins. Our sales estimates for 2006 include selling all our remaining gold coins and approximately a quarter of our remaining silver coins. Our current estimates do not include monetizing any assets for shipwrecks which may be recovered in 2006. We estimate that our cash requirements for operations and capital expenditures over the next twelve months will range from $18 million to $20 million. We may be required to reduce budgeted expenses if sales estimates are not attained. Our cash requirements are only estimates and may change to suit our business and operational requirements in 2006. However, we cannot guarantee the sales of our products and other available cash sources will generate sufficient cash flow to meet our overall cash requirements. If cash flow is not sufficient to meet our business requirements, we may be required to raise additional capital through other financing activities.

In December 2004, the Financial Accounting Standards Board (FASB) issued SFAS No. 123 (revised 2004) (SFAS No. 123R), Share-Based Payment . SFAS No. 123R will require the Corporation to expense share-based payments, including employee stock options, based on their fair value.

SFAS No. 123R permits public companies to adopt its requirements using one of two methods. The first adoption method is a “modified prospective” method in which compensation cost is recognized beginning with

the effective date (i) based on the requirements of SFAS No. 123R for all share-based payments granted after the effective date and (ii) based on the requirements of SFAS No. 123 for all awards granted to employees prior to the effective date of SFAS No. 123R that remain unvested on the effective date. The second adoption method is a “modified retrospective” method, which includes the requirements of the modified prospective method described above, but also permits entities to restate, based on the amounts previously recognized under SFAS No. 123 for purposes of pro forma disclosures, either (i) all prior periods presented or (ii) prior interim periods in the year of adoption.

The Corporation is required to adopt SFAS No. 123R effective as of January 1, 2006, and plans to utilize the modified prospective method of adoption. As permitted by SFAS No. 123, the Corporation currently accounts for share-based payments to employees under APBO No. 25 using the intrinsic value method and, as such, generally recognizes no compensation cost for employee stock options. Accordingly, we believe the adoption of SFAS No. 123R’s fair value method will not have a significant impact on the Corporation’s overall financial position. The impact of adoption of SFAS No. 123R cannot be predicted at this time because it will depend on levels of share-based payments granted in the future. However, had the Corporation adopted SFAS No. 123R in prior years, the impact of that adoption would have approximated the impact of SFAS No. 123 as described in the disclosure of pro forma net earnings and pro forma earnings per share in footnote B. SFAS No. 123R also requires the benefits of tax deductions in excess of recognized compensation cost to be reported as a financing cash flow, rather than as an operating cash flow as currently presented. This requirement will reduce net operating cash flows and increase net financing cash flows in periods after adoption.
