April, 2005, by and between ODYSSEY MARINE EXPLORATION, INC., a Nevada corporation, whose address is 5215 West Laurel Street, Tampa, Florida 33607 (“Borrower”), and MERCANTILE BANK, whose address is 2307 West Kennedy
Boulevard, Tampa, FL 33609 (“Lender”). 
 W I T N E S S E T H: 
 WHEREAS, Borrower desires to borrow money for business purposes, and Borrower has requested a line of credit from Lender, and Lender is willing to loan
certain sums to Borrower from time to time on the terms set forth herein; and 
 WHEREAS, certain capitalized terms used in this Agreement
are defined in Section 10 hereof; 
 NOW, THEREFORE, it is agreed as follows: 
 1. Revolving Credit Loan. 
 (a) Revolving Credit Commitment. Subject to the terms and conditions hereof, Lender agrees to make Advances to Borrower from time to time during the Commitment Period in an aggregate principal amount at any one time
outstanding not to exceed SIX MILLION AND 00/100 DOLLARS ($6,000,000.00) (the “Commitment”). As long as no Event of Default has occurred hereunder and no Default has occurred that, with the passage of time, the giving of notice, or both,
shall constitute an Event of Default hereunder, Borrower shall be entitled to borrow, repay or prepay and reborrow, by delivering to Lender a Draw Request in the form of Exhibit “A” attached hereto (“Draw Request”). 

(b) Revolving Credit Note. The Revolving Credit Loan shall be evidenced by a promissory note of Borrower payable to the order of Lender
substantially in the form of Exhibit “B” attached hereto (“Revolving Credit Note”). 
 (c) Interest. The
Revolving Credit Loan shall accrue interest as provided in the Revolving Credit Note. 
 (d) Borrower’s Loan Account.
Lender shall enter in its records of this Revolving Credit Loan all Advances under the Revolving Credit Loan and all payments made by or on behalf of Borrower on account thereof. Any payments shall be credited first to payment of any late charges,
fees or expenses, if any, then to accrued and unpaid interest and the balance, if any, (“Credit”) to principal. Lender shall provide Borrower a monthly accounting of transactions under the Revolving Credit Loan. Each such accounting shall
be deemed final, binding and conclusive upon Borrower in all respects as to all matters as reflected therein, unless Borrower, within thirty (30) days after the date the accounting is rendered, notifies Lender in writing of any objections,
describing the basis for such objections with specificity. In such event, only those items expressly objected to in the notice shall be deemed disputed by Borrower. 

 (e) Revolving Credit Commitment Period. The Commitment Period shall terminate on April
    , 2008 (the “Termination Date”) unless Borrower shall earlier terminate the Commitment. Lender shall review its Commitment hereunder annually, with the first review to occur on or about the first anniversary
hereof. 
 (f) Termination or Reduction of Commitment. Borrower shall have the right, upon not less than five (5) Business
Days’ written notice to Lender, to terminate or reduce the Commitment at any time, provided that any notice of termination shall be accompanied by payment in full of the Revolving Credit Loan and the Advances outstanding thereunder and provided
that any notice of reduction shall be accompanied by payment in full of the Revolving Credit Loan balance that exceeds the reduced Commitment. 
 (g) Unused Line Fee. Borrower hereby agrees to pay Lender an unused line fee at a rate equal to one-fourth of one percent (0.25%) per annum calculated upon the amount by which $6,000,000.00 exceeds the average daily principal
balance of the outstanding Advances during the immediately preceding calendar quarter (or part thereof) while this Agreement is in effect and for so long thereafter as any of the Advances are outstanding, which fee shall be payable quarterly in
arrears. 
 (h) Mandatory Payments. In the event that Lender shall notify Borrower that the current Revolving Credit Loan
balance exceeds the Commitment, Borrower shall immediately repay the Revolving Credit Loan by the amount of such excess. 
 (i)
Permissive Prepayments. Borrower may, at any time and from time to time, pay or prepay the Revolving Credit Loan, in whole or in part, without payment of any premium or penalty. 
 (j) Use of Proceeds. The proceeds of the Revolving Credit Loan shall be used by Borrower for working capital requirements. 
 2. Security. As security for the Loan, Borrower shall at Closing execute and deliver to Lender the Security Agreement, granting to Lender a
lien and security interest on, in and to all of the assets described on Exhibit “D” which is attached hereto and made a part hereof, now owned or hereafter acquired, and the proceeds and products thereof (“Collateral”) free of
all claims, liens and encumbrances except for claims, liens and encumbrances, if any, listed on Exhibit “D,” except for liens and encumbrances in favor of Lender, and except for Permitted Liens (as defined below). Borrower authorizes the
filing by Lender, in form and substance satisfactory to Lender, of UCC-1 financing statements describing the Collateral and determined by the Lender to be desirable to perfect the liens and security interests referred to in this paragraph.

 As further security for the Loan, Borrower hereby assigns and grants to Lender a security interest in and to all property of Borrower
which is or may hereafter be in Lender’s possession (by deposit, assignment, purchase or otherwise) in any capacity including but not limited to all monies owed or to be owed by Lender to Borrower, deposits (whether or not Lender has possession
of any certificate of deposit or other indicia of ownership), and stocks, bonds or other securities held in any securities trading account, custodial account or otherwise; and with respect to all such property, Lender shall have the same rights as
it has to any Collateral.

authorized officer on Lender’s behalf, and then only to the extent recited therein. A waiver, release or modification with reference to any one event shall not be construed as continuing or constituting a course of dealing, nor shall it be
