CAUTIONARY STATEMENT FOR PURPOSES OF THE PRIVATE SECURITIES LITIGATION REFORM
ACT OF 1995 AND OTHER FEDERAL SECURITIES LAWS

     We are including the following discussion to inform our existing and
potential security holders generally of some of the risks and uncertainties
that can affect us and to take advantage of the "safe harbor" protection for
forward-looking statements afforded under federal securities laws. From time
to time, our management or persons acting on our behalf make forward-looking
statements to inform existing and potential security holders about us. 
Statements that are not historical in nature, particularly those that utilize
terminology such as "may," "will," "should," "likely," "expects,"
"anticipates," "estimates," "believes" or "plans," or comparable terminology,
are forward-looking statements based on current expectations and assumptions,
and entail various risks and uncertainties that could cause actual results to
differ materially from those expressed in such forward-looking statements.

                               COMPANY SUMMARY

     Odyssey Marine Exploration, Inc. ("Odyssey," "we" or "us") 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.

     Our corporate offices are located at 5215 West Laurel Street, Tampa,
Florida 33607.  Our telephone number is (813) 876-1776.

                                  RISK FACTORS

     Investing in the shares is very risky.  You should be able to bear a
complete loss of your investment.  In deciding whether to purchase the shares,
you should carefully consider the following factors, among others, as well as
information contained in this prospectus, our most recent annual report on
Form 10-KSB and quarterly reports on Form 10-QSB and the other documents
incorporated by reference into this Prospectus:

     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

                                     4
 
data which has been compiled regarding various projects, the quality and
reliability of such research and data is unknown.  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 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 can be no assurance as to the value
that such objects will bring at their sale, as the market for such objects is
very uncertain.

     The research and data we use may not be reliable.

     The success of a shipwreck project will be 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.

     Recovery efforts 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.

     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
you that 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.

     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 recent 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 for these items.




                                     5





     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.

     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 that we will not be successful in obtaining title to, 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.

     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.

                                USE OF PROCEEDS

     Odyssey will not receive any proceeds from the sale of the common stock
by the selling shareholders.

     To the extent that any of the warrants held by the selling shareholders
are exercised, up to approximately $11,095,000 may be received by Odyssey. 
Any net proceeds received from the exercise of the warrants will be used for
general corporate purposes.

                    RECENT MATERIAL CHANGES IN OUR BUSINESS

     There have been no material changes in our business since December 31,
2004, that have not been reported in our Reports on Form 10-QSB or Form 8-K.

                             PLAN OF DISTRIBUTION

     The selling shareholders and their successors, including their
transferees, pledgees or donees of their successors, may sell the common stock
directly to purchasers or through underwriters, broker-dealers or agents, who
may receive compensation in the form of discounts, concessions or commissions
from the selling holders or the purchasers.  These discounts, concessions or
commissions as to any particular underwriter, broker-dealer or agent may be in
excess of those customary in the types of transactions involved.

     The common stock may be sold in one or more transactions at fixed prices,
at prevailing market prices at the time of sale, at prices related to the
prevailing market prices, at varying prices determined at the time of sale, or
at negotiated prices.  These sales may be effected in transactions, which may
involve crosses or block transactions:

     - on any national securities exchange on which the common stock 
       may be listed, or U.S. inter-dealer system of a registered national
       securities association on which the common stock may be listed or
       quoted at the time of sale;

     - in the over-the-counter market;

     - in transactions otherwise than on these exchanges or systems or
       in the over-the-counter market; or

     - through the writing of options, whether the options are listed on
       an options exchange or otherwise.

     In connection with the sale of the common stock or otherwise, the selling
shareholders may enter into hedging transactions with broker-dealers or other
financial institutions, which may in turn engage in short sales of the common
stock in the course of hedging the positions they assume. 


                                     8



     The aggregate proceeds to the selling shareholders from the sale of the
common stock offered by them will be the purchase price of the common stock
less discounts and commissions, if any.  Each of the selling shareholders
reserves the right to accept and, together with their agents from time to
time, to reject, in whole or in part, any proposed purchase of common stock to
be made directly or through agents.  We will not receive any of the proceeds
from this offering.

     In order to comply with the securities laws of some states, if
applicable, the common stock may be sold in these jurisdictions only through
registered or licensed brokers or dealers.  In addition, in some states the 
common stock may not be sold unless they have been registered or qualified for
sale or an exemption from registration or qualification requirements is
available and is complied with.

     The selling shareholders and any underwriters, broker-dealers or agents
that participate in the sale of the common stock may be "underwriters" within
the meaning of Section 2(11) of the Securities Act.  Any discounts,
commissions, concessions or profit they earn on any resale of the shares may
be underwriting discounts and commissions under the Securities Act.  Selling
shareholders who are "underwriters" within the meaning of Section 2(11) of the
Securities Act will be subject to the prospectus delivery requirements of the
Securities Act.  The selling shareholders have acknowledged that they
understand their obligations to comply with the provisions of the Exchange Act
and the rules thereunder relating to stock manipulation, particularly
Regulation M.

     In addition, any securities covered by this prospectus that qualify for
sale pursuant to Rule 144 of the Securities Act may be sold under Rule 144
rather than pursuant to this prospectus.  A selling shareholder may not sell
any common stock described in this prospectus and may not transfer, devise or
gift these securities by other means not described in this prospectus.

     To the extent required, the specific common stock to be sold, the names
of the selling shareholders, the respective purchase prices and public
offering prices, the names of any agent, dealer or underwriter, and any
applicable commissions or discounts with respect to a particular offer will be
set forth in an accompanying prospectus supplement to, if appropriate, a
post-effective amendment to the registration statement of which this
prospectus is a part.

     The registration statement of which this prospectus is a part is being
filed pursuant to registration rights that we have provided to the selling
shareholders under applicable federal and state securities laws under specific
circumstances and at specific times.  We will pay all of the expenses incurred
in connection with the registration of the common stock.

                            DESCRIPTION OF SECURITIES

     Odyssey has 109,810,000 authorized shares of stock, consisting of
100,000,000 shares of common stock, having a par value of $.0001 per share,
and 9,810,000 shares of preferred stock, having a par value of $.0001 per
share.





                                     9





COMMON STOCK

     As of March 16, 2005, there were 41,308,099 shares of common stock
outstanding.  All such outstanding shares of common stock are fully paid and
non-assessable.  Each share of common stock has an equal and ratable right to
receive dividends when declared by the Board of Directors of Odyssey out of
assets legally available for that purpose and subject to the dividend
obligations of Odyssey to holders of any preferred stock then outstanding.

     In the event of a liquidation, dissolution or winding up of Odyssey, the
holders of common stock are entitled to share equally and ratably in the
assets available for distribution after payment of all liabilities, and
subject to any prior rights of any holders of preferred stock outstanding at
that time.

     The holders of common stock have no preemptive, subscription, conversion
or redemption rights, and are not subject to further calls or assessments of
Odyssey.  Each share of common stock is entitled to one vote in the election
of directors and on all other matters submitted to a vote of stockholders. 
Cumulative voting in the election of directors is not permitted.

PREFERRED STOCK

     Preferred stock may be issued from time to time in one or more series,
and the board of directors, without further approval of the stockholders, is
authorized to fix the dividend rates and terms, conversion rights, voting
rights, redemption rights and terms, liquidation preferences and any other
rights, preferences, privileges and restrictions applicable to each series of
preferred stock.  The purpose of authorizing the board of directors to
determine such rights, preferences, privileges and restrictions is to
eliminate delays associated with a stockholder vote on specific issuances. 
The issuance of preferred stock, while providing flexibility in connection
with possible acquisitions and other corporate purposes, could, among other
things, adversely affect the voting power of the holders of common stock and,
under some circumstances, make it more difficult for a third party to gain
control of Odyssey.  There are currently no shares of preferred stock
outstanding.

WARRANTS

     This Prospectus covers the resale of common stock issuable upon the
exercise of certain warrants.  Of the warrants, 2,700,000 were included in the
units which were sold to four institutional investors in a private placement
that was completed on March 10, 2005.  In addition, a total of 470,000
warrants were issued to two assignees of the placement agent for the private
offering as part of the commission for the offering.  The warrants give the
holders the right to purchase common stock at an exercise price of $3.50 per
share during the two year period expiring on March 9, 2007.


                                LEGAL MATTERS

     The legality of the shares offered hereby are being passed upon for
Odyssey by Krys Boyle, P.C., 600 17th Street, Suite 2700 South, Denver,

beneficially owns 311,784 shares of Odyssey's common stock.

ITEM 15. INDEMNIFICATION OF OFFICERS AND DIRECTORS.

     The only statute, charter provision, bylaw, contract, or other
arrangement under which any controlling person, director or officer of Odyssey
is insured or indemnified in any manner against any liability which he may
incur in his capacity as such, is as follows:

     (a)  Subsection (1) of Section 78.751 of the Nevada Corporation Law
empowers a corporation to "indemnify any person who is a party or is
threatened to be made a party to any threatened, pending or completed action,
suit or proceeding, whether civil, criminal, administrative or investigative,
except an action by or in the right of the corporation, by reason of the fact
that he is or was a director, officer, employee or agent of the corporation,
or is or was serving at the request of the corporation as a director, officer,
employee or agent of another corporation, partnership, joint venture, trust or
other enterprise, against expenses, including attorneys' fees, judgments,
fines and amounts paid in settlement actually and reasonably incurred by him
in connection with the action, suit or proceeding if he acted in good faith
and in a manner which he reasonably believed to be in or not opposed to the
best interests of the corporation, and, with respect to any criminal action or
proceeding, had no reasonable cause to believe his conduct was unlawful.  The
termination of any action, suit or proceeding by judgment, order, settlement,
conviction, or upon a plea of nolo contendere or its equivalent, does not, of
itself, create a presumption that the person did not act in good faith and in
a manner which he reasonably believed to be in or not opposed to the best
interests of the corporation, and that, with respect to any criminal action or
proceeding, he had reasonable cause to believe that his conduct was unlawful."

     Subsection (2) of Section 78.751 empowers a corporation to "indemnify any
person who was or is a party or is threatened to be made a party to any
threatened, pending or completed action or suit by or in the right of the
corporation to procure a judgment in its favor by reason of the fact that he
is or was a director, officer, employee or agent of the corporation, or is or
was serving at the request of the corporation as a director, officer, employee
or agent of another corporation, partnership, joint venture, trust or other
enterprise against expenses, including amounts paid in settlement and
attorneys' fees actually and reasonably incurred by him in connection with the
defense or settlement of the action or suit if he acted in good faith and in a
manner which he reasonably believed to be in or not opposed to the best
interests of the corporation.  Indemnification may not be made for any claim,
issue or matter as to which such a person has been adjudged by a court of



                                     II-1



competent jurisdiction, after exhaustion of all appeals therefrom, to be
liable to the corporation or for amounts paid in settlement to the
corporation, unless and only to the extent that the court in which the action
or suit was brought or other court of competent jurisdiction determines upon
application that in view of all the circumstances of the case, the person is
fairly and reasonably entitled to indemnify for such expenses as the court
deems proper."

     Subsection 78.751(3) further provides that "to the extent that a
director, officer, employee or agent of a corporation has been successful on
the merits or otherwise in defense of any action, suit or proceeding referred
to in subsections 1 and 2, or in defense of any claim, issue or matter herein,
he must be indemnified by the corporation against expenses, including
attorneys' fees, actually and reasonably incurred by him in connection with
the defense."

     (b)  Article VII of Odyssey's Articles of Incorporation provides that
Odyssey is authorized to indemnify directors, officers, employees and agents
to the full extent allowed for under the Nevada Business Corporation Act.

     (c)  Article XI of the Articles of Incorporation of Odyssey provides that
no director, officer or stockholder of Odyssey shall be personally liable for
damages for breach of fiduciary duty as a director or officer; provided, that
this provision shall not eliminate liability of a director or officer for acts
or omissions involving intentional misconduct, fraud or a knowing violation of
law or payments or distributions in violation of Nevada law.

ITEM 17.  UNDERTAKINGS.

     The undersigned registrant hereby undertakes: 

     (1)  To file, during any period in which offers or sales are being made,
a post-effective amendment to this registration statement: 

          (i)   To include any prospectus required by Section 10(a)(3) of the
1933 Act; 

          (ii)  To reflect in the prospectus any facts or events arising after
the effective date of the registration statement (or the most recent
post-effective amendment thereof) which, individually or in the aggregate,
represent a fundamental change in the information set forth in the
registration statement. Notwithstanding the foregoing, any increase or
decrease in volume of securities offered (if the total dollar value of
securities offered would not exceed that which was registered) and any
deviation from the low or high end of the estimated maximum offering range may
be reflected in the form of prospectus filed with the Commission pursuant to
Rule 424(b) ([Section] 230.424(b) of this chapter) if, in the aggregate, the
changes in volume and price represent no more than a 20% change in the maximum
aggregate offering price set forth in the "Calculation of Registration Fee"
table in the effective registration statement.

          (iii) To include any material information with respect to the plan
of distribution not previously disclosed in the registration statement or any
material change to such information in the registration statement;  

Provided, however, that paragraphs (l)(i) and (l)(ii) do not apply if the
registration statement is on Form S-3 or Form S-8, and the information
required to be included in a post-effective amendment by those paragraphs is
contained in periodic reports filed by Odyssey pursuant to Section 13 or
Section 15(d) of the 1934 Act that are incorporated by reference in the
registration statement. 

     (2)  That, for the purpose of determining any liability under the 1933
Act, each such post-effective amendment shall be deemed to be a new
registration statement relating to the securities offered therein, and the
offering of such securities at that time shall be deemed to be the initial
bona fide offering thereof. 

     (3)  To remove from registration by means of a post-effective amendment
any of the securities being registered which remain unsold at the termination
of the offering.

     The undersigned registrant hereby undertakes that, for purposes of
determining any liability under the Securities Act of 1933, each filing of the
registrant's annual report pursuant to section 13(a) or section 15(d) of the
Securities Exchange Act of 1934(and, where applicable, each filing of an
employee benefits plan annual report pursuant to section 15(d) of the
Securities Exchange Act of 1934) that is incorporated by reference in this
Registration Statement shall be deemed to be a new registration statement
relating to the securities offered herein, and the offering of such securities
at that time shall be deemed to be the initial bona fide offering thereof.

     Insofar as indemnification for liabilities arising under the 1933 Act may
be permitted to directors, officers and controlling persons of Odyssey



                                     II-3


pursuant to the foregoing provisions, or otherwise, Odyssey has been advised
that in the opinion of the Commission such indemnification is against public
policy as expressed in the 1933 Act and is, therefore, unenforceable. In the
event that a claim for indemnification against such liabilities (other than
the payment by Odyssey of expenses incurred or paid by a director, officer or
controlling person of Odyssey in the successful defense of any action, suit or
proceeding) is asserted by such director, officer or controlling person in
connection with the securities being registered, Odyssey will, unless in the
opinion of its counsel the matter has been settled by controlling precedent,
submit to a court of appropriate jurisdiction the question whether such
indemnification by it is against public policy as expressed in the 1933 Act
and will be governed by the final adjudication of such issue.
