ITEM 1. BUSINESS

Overview

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.

Business Segments

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.

Project Criteria

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 shipwreck must be in deep water, thereby minimizing the possibility that it has been broken up and covered by shifting sands or the target of previous recovery efforts.
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | The research must indicate that the shipwreck was carrying enough intrinsically valuable cargo to pay for the high cost associated with deep-ocean archaeological recovery, and to
provide an attractive return for our investors and stockholders.
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | The research must provide good navigational information concerning the sinking location in order to minimize the search area and provide a reasonable expectation that the wreck can
be found.
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | The issues relating to ownership of the shipwreck and its cargo must be resolved or reasonably predictable prior to beginning any recovery in order to minimize the potential for
litigation.
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

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.

Technology

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.

Equipment

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.

##### Table of Contents

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 SSRepublicshipwreck 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 ofZEUS, 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.

Active Operational Projects

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.

SS Republic Project

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.

##### Table of Contents

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.

Western Mediterranean Project

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.

Atlas Search Project

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.

HMS Sussex Project

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.

##### Table of Contents

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:



|                            |  |                   |  |        
|--------------------------- |  | ----------------- |  | -------
|Range                       |  | BritishGovernment |  | Odyssey
|$0 - $45 million            |  | 20%               |  | 80%    
|$45 million to $500 million |  | 50%               |  | 50%    
|Above $500 million          |  | 60%               |  | 40%    

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 is not HMS Sussex;
| | - |  | --------------------------------



| |  |  | we are in serious breach of our obligations under our agreement with the British Government.
| | - |  | --------------------------------------------------------------------------------------------

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

##### Table of Contents

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.

Other Projects

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.

Sales and Marketing

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.

##### Table of Contents

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.

Archaeology and Science

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.

Legal and Political Issues

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

##### Table of Contents

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.

Competition

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.

Cost of Environmental Compliance

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.

ITEM 1A. RISK FACTORS

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.

Our business involves a high degree of risk.

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 research and
data we use may not be reliable.

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.

Availability of raw materials may be limited.

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.

Operations may be affected by natural hazards.

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.

We may be unable to establish our rights to any objects we recover.

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.

##### Table of Contents

The market for any objects we recover is uncertain.

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.

Objects we recover could be stolen from us.

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.

We face competition from others.

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.

We may be unable to get permission to conduct salvage
operations.

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.

##### Table of Contents

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 generic
preferred stock.

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.

ITEM 1B. UNRESOLVED STAFF COMMENTS

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.

ITEM 2. PROPERTIES

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.

ITEM 3. LEGAL PROCEEDINGS

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

##### Table of Contents

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 4. SUBMISSION OF MATTERS TO A VOTE OF SECURITIES HOLDERS

None.

Revenue

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 and Expenses

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.

Income Taxes

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.

General Discussion

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.

##### Table of Contents

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.

Revenue

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 Republicbegan
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.

Costs and Expenses

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 SSRepublic 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 SSRepublic 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.

Income Taxes

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.

Source and Use of Funds

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

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

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.

Critical Accounting Estimates

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.

Long-lived Assets

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.

Realizability of Deferred Tax Assets

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.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

The Board of Directors

Odyssey Marine Exploration, Inc. and Subsidiaries

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.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM ON

INTERNAL CONTROL OVER FINANCIAL REPORTING

The Board of Directors

Odyssey Marine Exploration, Inc.
and Subsidiaries

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
Frameworkissued 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 inInternal Control  Integrated Frameworkissued by COSO.

Summary of Significant Non-Cash Transactions

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. AND SUBSIDIARIES

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS

NOTE A  ORGANIZATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Organization

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.

Summary of Significant Accounting Policies

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

Principles of Consolidation

The consolidated
financial statements include the accounts of the Company and its 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.

Reclassifications

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.

Use of Estimates

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

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 Recognition and Accounts Receivable

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.

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS(Continued)



Cash and Cash Equivalents

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.

Fair Value of Financial Instruments

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.

Inventory

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.

Long-Lived Assets

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.

Comprehensive Income

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 and Depreciation

Property and equipment is stated at historical cost. Depreciation is provided using the straight-line method at rates based on the assets estimated
useful lives which 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.

Earnings Per Share

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:



|                                                        |  |      |           |      |   |

Stock-Based Compensation

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.

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS(Continued)



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:



|                                    |  |         |   |  |         |   |  |           |  
|----------------------------------- |  | ------- | - |  | ------- | - |  | --------- | -
|                                    |  | 2005    |   |  | 2004    |   |  | 2003      |  
|Risk-free interest rate             |  | 4.3     | % |  | 3.6     | % |  | 3.0       | %
|Expected volatility of common stock |  | 62.4    | % |  | 469     | % |  | 496       | %
|Dividend Yield                      |  | 0       | % |  | 0       | % |  | 0         | %
|Expected life of options            |  | 5 years |   |  | 5 years |   |  | 4-5 years |  

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

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)

NOTE B  CONCENTRATION OF CREDIT RISK

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.

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:

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.

NOTE K  MORTGAGE PAYABLE

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:

NOTE L  LOAN PAYABLE

Revolving Credit Facility

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.

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.

NOTE N  RELATED PARTY TRANSACTIONS

On
December 9, 2002, a Georgia limited liability company acquired rights from an unrelated third party through a foreclosure sale to receive 5% of post finance cost proceeds, if any, from shipwrecks that we may recover within a predefined search
area of the Mediterranean Sea. The shipwreck we believe to be HMS Sussex is located within this search area. Two of our officers and directors 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.

NOTE O  SALE OF REVENUE PARTICIPATION CERTIFICATES

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.

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS(Continued)



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.

NOTE P  PREFERRED STOCK

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.

Series C Preferred Stock

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.

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:

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.

The
change in the valuation allowance is as follow:

capital.

NOTE S  MAJOR CUSTOMERS

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.

NOTE T  SEGMENT REPORTING

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

NOTE U  COMMITMENTS AND CONTINGENCIES

Rights to Future Revenues, If Any

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)

Legal Proceedings

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.

Partnering Agreement

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:

|Above $500 million          |  | 60                 | % |  | 40      | %

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.

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.

Trends and Uncertainties

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.

NOTE V  RECENTLY ISSUED ACCOUNTING STANDARDS

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



53

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS(Continued)



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.

NOTE W  SUBSEQUENT EVENT (UNAUDITED)

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.
