Exhibit 10.2 Form 8-K Viking Systems, Inc. File No. 000-49636 VIKING SYSTEMS, INC. STOCK OPTION AGREEMENT This Agreement is entered into this 18th day of December 2003, by and between Viking Systems, Inc., a Nevada corporation ("Corporation") and Donald E. Tucker (" Tucker"). Recitals Tucker has provided funds to the Corporation to be used to pay professional fees related to various corporate filings and to pay for other corporate expenses. In exchange for such funds, the Corporation issued Tucker 3,200,000 shares of its common stock at a price of $.02 per share. The Corporation intends to acquire certain assets from Vista Medical Technologies, Inc., pursuant to an Asset Purchase Agreement. The purchase price for such assets includes a cash portion of up to $400,000 and the issuance of approximately 3,100,000 shares of the Corporation's common stock. The Corporation has requested that Tucker purchase additional shares of the Corporations capital stock in the amount of $400,000 to provide the Corporation with the funds necessary to make such cash payment. Tucker has agreed to make such additional investment in the Corporation on the same terms and conditions as his initial purchase of 3,200,000 shares of the Corporation's common stock. The Corporation does not have sufficient shares of common stock authorized for issuance to Tucker to fund the $400,000 requirement of the acquisition of assets. Accordingly, the Corporation has offered to issue Tucker 5,000,000 shares of its preferred stock in lieu of common stock. The Corporation has designated a Series A Preferred Stock which is convertible into common stock on a basis of one share of Series A Preferred Stock convertible into four shares of common stock. The Corporation has agreed to grant Tucker an option to purchase 5,000,000 shares of the Corporation's Series A Preferred Stock on the terms and conditions set forth herein. NOW THEREFORE, it is agreed as follows: Agreement 1. Grant of Option. Subject to the terms and conditions of this Agreement, the Corporation hereby grants to Tucker the option ("Option") to purchase from the Corporation up to an aggregate of 5,000,000 shares of the Corporation's Series A Preferred Stock ("Option Shares"), from time to time, at a price of $.08 per Share ("Exercise Price"). The Option is fully vested and is now exercisable in part or in full. 2. Exercise of Option. The Option granted herein expires on March 31, 2004 and must be exercised, if at all, on or before March 31, 2004. This Option may be exercised in whole or in part by delivery to the Corporation, from time to time, of a written notice signed by Tucker, specifying the number of Option Shares that Tucker then desires to purchase, together with cash, certified check, or bank draft payable to the order of the Corporation for an amount equal to the Exercise Price of such Shares. 3. Shares to be Fully Paid. The Corporation covenants and agrees that all Option Shares, will, upon issuance and, if applicable, payment of the applicable Exercise Price, be duly authorized, validly issued, fully paid and nonassessable, and free of all liens and encumbrances, except for restrictions on transfer provided for herein or under applicable federal and state securities laws. 4. Adjustments. The Exercise Price and the number of shares purchasable hereunder are subject to adjustment from time to time as follows: 4.1 Merger, Sale of Assets, etc. If at any time while this Option, or any portion hereof, is outstanding and unexpired there shall be (i) a reorganization (other than a combination, reclassification, exchange or subdivision of shares otherwise provided for herein), (ii) a merger or consolidation of the Corporation with or into another corporation in which the Corporation is not the surviving entity, or a reverse triangular merger in which the Corporation is the surviving entity but the shares of the Corporation's capital stock outstanding immediately prior to the merger are converted by virtue of the merger into other property, whether in the form of securities, cash, or otherwise, or (iii) a sale or transfer of the Corporation's properties and assets as, or substantially as, an entirety to any other person, then, as a part of such reorganization, merger, consolidation, sale or transfer, lawful provision shall be made so that the holder of this Option shall thereafter be entitled to receive upon exercise of this Option, during the period specified herein and upon payment of the Exercise Price then in effect, the number of shares of stock or other securities or property of the successor corporation resulting from such reorganization, merger, consolidation, sale or transfer that such holder would have been entitled to receive in such reorganization, consolidation, merger, sale or transfer if this Option had been exercised immediately before such reorganization, merger, consolidation, sale or transfer. 4.2 Reclassifications, etc. If the Corporation, at any time while this Option, or any portion hereof, remains outstanding and unexpired by reclassification of securities or otherwise, shall change any of the securities as to which purchase rights under this Option exist into the same or a different number of securities of any other class or classes, this Option shall thereafter represent the right to acquire such number and kind of securities as would have been issuable as the result of such change with respect to the securities that were subject to the purchase rights 2 under this Option immediately prior to such reclassification or other change and the Exercise Price therefor shall be appropriately adjusted. 4.3 Split, Subdivision or Combination of Shares. If the Corporation at any time while this Option, or any portion hereof, remains outstanding and unexpired shall split, subdivide or combine the securities as to which purchase rights under this Option exist, into a different number of securities of the same class, the Exercise Price for such securities shall be proportionately decreased in the case of a split or subdivision or proportionately increased in the case of a combination. 5.
