Exhibit 10.4 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 Daniel F. Crowley, a Director of the Corporation (" Crowley"). Recitals In consideration for Crowley agreeing to serve as a director of the Corporation, the Company has agreed to grant Crowley an option to purchase shares of the Corporation's common stock. The purpose of granting this option to Crowley is to promote the success of the Corporation and to advance the interests of the Corporation by providing an additional means, through the grant of this stock option, to motivate, retain and reward Crowley with an incentive for high levels of individual performance and improved financial performance of the Corporation. The Board of Directors of the Corporation has granted the option provided for herein in accordance with Rule 16b-3(d)(1) promulgated under the Securities Exchange Act of 1934, as amended (the "Act"). The grant of the option provided for herein, and the exercise of such options, shall be exempt from Section 16(b) of the Act; 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 Crowley, the option ("Option") to purchase from the Corporation up to an aggregate of 200,000 shares of the Corporation's common stock ("Option Shares"), from time to time, at a price of $.02 per Share ("Exercise Price"). The Option is fully vested and is now exercisable in part or in full. 2. NSO. The Option granted hereunder shall be deemed to be a Non-Statutory Stock Option (NSO). 3. Exercise of Option. The Option granted herein expires on December 31, 2008 and must be exercised, if at all, on or before December 31, 2008. 3.1. Manner of Exercise. 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 Crowley, specifying the number of Option Shares that Crowley then desires to purchase, together with: (i) cash, certified check, or bank draft payable to the order of the Corporation or (ii) other form of payment acceptable to the Corporation's Board of Directors, for an amount equal to the Exercise Price of such Shares. Crowley may pay all or a portion of the Exercise Price, and/or the tax withholding liability with respect to the exercise of the Option either by surrendering shares of stock already owned by Crowley or by withholding Option Shares, provided that the Board determines that the fair market value of such surrendered stock or withheld Option Shares is equal to the corresponding portion of such Exercise Price and/or tax withholding liability, as the case may be, to be paid for therewith. 3.2. Certificates. Promptly after any exercise in whole or in part of the Option by Crowley, the Corporation shall deliver to Crowley a certificate or certificates for the number of Option Shares with respect to which the Option was so exercised, registered in Crowley's name. 4. Restriction on Transferability. This Option is not transferable by Crowley otherwise than by testamentary will or the laws of descent and distribution and, during Crowley's lifetime, may be exercised only by Crowley or Crowley's guardian or legal representative. Except as permitted by the preceding sentence, neither this Option nor any of the rights and privileges conferred thereby shall be transferred, assigned, pledged, or hypothecated in any way (whether by operation of law or otherwise), and no such option, right, or privilege shall be subject to execution, attachment, or similar process. Upon any attempt to transfer this Option, or of any right or privilege conferred thereby, contrary to the provisions hereof, or upon the levy of any attachment or similar process upon such option, right, or privilege, this Option and any such rights and privileges shall immediately become null and void. 5. Exercise in Event of Death or Disability. Whenever the word "Crowley" is used in any provision of this Agreement under circumstances when the provision should logically be construed to apply to Crowley's guardian, legal representative, executor, administrator, or the person or persons to whom the Option may be transferred by testamentary will or by the laws of descent and distribution, the word "Crowley" shall be deemed to include such person or persons. 6. No Rights As Shareholder Prior To Exercise. Crowley shall not, by virtue hereof, be entitled to any rights of a shareholder in the Corporation, either at law or equity. The rights of Crowley are limited to those expressed in this Option and are not enforceable against the Corporation except to the extent set forth herein. 7. Registration of Option Shares. The Option Shares have not been registered with the Securities and Exchange Commission. The Company shall use its best efforts to register the Options Shares on Form S-8 with the Securities and Exchange Commission as soon as practical. 2 8. Anti-Dilution Provisions. The number and kind of Shares purchasable upon the exercise of this Option and the exercise price shall be subject to adjustment from time to time as follows: 8.1. In case the Corporation shall (i) pay a dividend or make a distribution on the outstanding Shares payable in Shares, (ii) subdivide the outstanding Shares into a greater number of Shares, (iii) combine the outstanding Shares into a lesser number of Shares, or (iv) issue by reclassification of the Shares any Shares of the Corporation, Crowley shall thereafter be entitled, upon exercise, to receive the number and kind of shares which, if this Option had been exercised immediately prior to the happening of such event, Crowley would have owned upon such exercise and been entitled to receive upon such dividend, distribution, subdivision, combination, or reclassification. 8.2. In case the Corporation shall consolidate or merge into or with another corporation, or in case the Corporation shall sell or convey to any other person or persons all or substantially all the property of the Corporation, Crowley shall thereafter be entitled, upon exercise, to receive the kind and amount of shares, other securities, cash, and property receivable upon such consolidation, merger, sale, or conveyance by a holder of the number of Shares which might have been purchased upon exercise of this Option immediately prior to such consolidation, merger, sale, or conveyance, and shall have no other conversion rights. In any such event, effective provision shall be made, in the certificate or articles of incorporation of the resulting or surviving corporation, in any contracts of sale and conveyance, or otherwise so that, so far as appropriate and as nearly as reasonably may be, the provisions set forth herein for the protection of the rights of Crowley shall thereafter be made applicable. 8.3. Whenever the number of Shares purchasable upon exercise of this Option is adjusted pursuant to this Section, the exercise price per Share shall be adjusted simultaneously by multiplying that exercise price per Share in effect immediately prior to such adjustment by a fraction, of which the numerator shall be the number of Shares purchasable upon exercise of this Option immediately prior to such adjustment, and of which the denominator shall be the number of Shares so purchasable immediately after such adjustment, so that the aggregate exercise price of this Option remains the same. 8.4. The existence of the Option shall not affect in any way the right or power of the Corporation or its shareholders to make or authorize any adjustments, recapitalization, reorganization, or other changes in the Corporation's capital structure or its business, or any merger or consolidation of the Corporation, or any issue of bonds, debentures, preferred shares with rights greater than or affecting the Shares, or the dissolution or liquidation of the Corporation, or any sale or transfer of all or any part of its assets or business, or any other corporate act or proceeding, whether of a similar character or otherwise. 3 9. Termination of Status as Director. If Crowley's services as a director of the Corporation shall terminate by reason of death or disability, or if he is not reelected or reappointed to the Board of Directors, the Option granted hereby shall remain exercisable for six months after the date of such termination but not later than December 31, 2008. If Crowley shall resign from the Board of Directors, this option shall immediately terminate and no longer be exercisable. 10. Notices.
