On September 20, 2005, the Board of Directors of Odyssey Marine Exploration, Inc. ("Odyssey" or the "Company") approved the immediate vesting of unvested and "underwater" stock options to purchase 212,500 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. Included in the options that were vested are options to purchase 50,000 shares held by Davis D. Howe, the Company's Chief Operating Officer and options to purchase 25,000 shares held by Michael J. Holmes, the Company's Chief Financial Officer. The exercise price of the options was not changed. The primary purpose of the accelerated vesting of these "out of the money" options is 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 Company's Board of Directors believes that this action is in the best interest of the Company and its shareholders. SIGNATURES Pursuant to the requirements of the Securities Exchange Act of 1934, the Registrant has duly caused this Report to be signed on its behalf by the undersigned, hereunto duly authorized. ODYSSEY MARINE EXPLORATION, INC. Dated: September 26, 2005 By: /s/ Michael J. Holmes Michael J. Holmes, Chief Financial Officer
