MacDougald (collectively, the "Reporting Persons"), as amended by Amendment No. 1 thereto filed on October 25, 2001 ("Amendment No. 1"), Amendment No. 2 thereto filed on November 20, 2003 ("Amendment No. 2"), Amendment No. 3 thereto filed on September 23, 2004 ("Amendment No. 3"), Amendment No. 4 thereto filed on September 28, 2004 ("Amendment No. 4"), and Amendment No. 5 thereto filed on February 4, 2005 ("Amendment No. 5"). This Amendment No. 6, together with the Initial Schedule 13D, Amendment No. 1, Amendment No. 2, Amendment No. 3, Amendment No. 4, and Amendment No. 5 are referred to collectively as the "Schedule 13D". The information set forth in Items 1 and 4 below are being included for reference purposes, but no change has occurred with respect to such information. Unless otherwise defined herein, all capitalized terms shall have the meanings ascribed to them in the Schedule 13D. This Amendment No. 6 is being filed to correct the number of shares of the Common Stock (defined below) held by the Reporting Persons totaling the sale of shares reported in Amendment No. 5. Item 1. Security of Issuer This Amendment No. 6 relates to shares of common stock, $0.0001 par value per share ("Common Stock"), of Odyssey Marine Exploration, Inc., a Nevada corporation (the "Issuer"), whose principal executive offices are located at 3604 Swann Avenue, Tampa, Florida 33609. Item 4. Purpose of Transaction This amendment is being filed to correct the disclosures set forth in Amendment No. 5 regarding the number of shares of Common Stock held by the Reporting Person following the reported sale by MFLP of an aggregate of 1,250,000 shares of Common Stock on February 2, 2005 in open market transactions. See Item 5(a) of this Amendment No. 6. With respect to its remaining holdings of Common Stock, MFLP will continue to monitor its investment in, and ownership of, the Common Stock and may, as result thereof, determine to sell, transfer, or exchange the Common Stock with or to affiliates or third parties through private placements or market sales, acquire additional Common Stock, warrants, or options, or maintain its ownership position. Except as indicated in the Schedule 13D, the Reporting Persons have no plans or proposals which relate to or would result in: (a) the acquisition by any person of additional securities of the Issuer, or the disposition of securities of the Issuer; (b) an extraordinary corporate transaction, such as a merger, organization or liquidation, involving the Issuer or any of its subsidiaries; (c) a sale or transfer of a material amount of assets of the Issuer or any of its subsidiaries; (d) any change in the present board of directors or management of the Issuer, including any plans or proposals to change the number or term of directors or to fill any existing vacancies on the board; (e) any material change in the present capitalization or dividend policy of the Issuer; Page 5 of 7 Pages (f) any other material change in the Issuer's business or corporate structure; (g) changes in the Issuer's charter, bylaws or instruments corresponding thereto or other actions which may impede the acquisition of control of the Issuer by any person; (h) causing a class of securities of the Issuer to be delisted from a national securities exchange or to cease to be authorized to be quoted in an inter-dealer quotation system of a registered national securities association; (i) a class of equity securities of the Issuer becoming eligible for termination of registration pursuant to Section 12(g)(4) of the Act; or (j) any action similar to any of those enumerated above. Item 5. Interest in Securities of Issuer (a) As of the date of hereof, the Reporting Persons beneficially own an aggregate of 2,344,008 shares of Common Stock, which represents approximately 6.0% of the shares of Common Stock which were outstanding as of January 21, 2005 (as reported by the Issuer in its definitive proxy statement filed on January 28, 2005). Amendment No. 5 erroneously indicated that the number of such shares of Common Stock held by the Reporting Person was 2,344,008. This was a computation error which is corrected hereby. (b) For purposes of Section 13 of the Securities Act of 1933, as amended, MMI may be deemed to control MFLP, and James E. MacDougald may be deemed to control MMI and MFLP. Each of the Reporting Persons may thus be considered to beneficially own and to have sole voting and dispositive power with respect to all the Securities beneficially owned by MFLP. (c) No sales of the Common Stock by the Reporting Persons have taken place since those reported in Amendment No. 5. Item 7. Material to Be Filed as Exhibits None.
