DROBNY, JR., ("Drobny"), having an address for notices at 2457 Summerwood Drive, Gulfport, MS 39507, who agree as follows: 1. Hiring. The Company hereby hires Drobny as, and Drobny hereby agrees to act as Vice President of Application Development. The Company and Drobny intend to enter into an employer-employee relationship, subject to the terms of this Agreement, based upon Drobny's ability to design and build integrated information and communication systems in the marine industry and other related technical skills and further upon Drobny's ability to expand and develop the Company's ability to offer its customers integrated marine information systems. 2. Duties. Drobny shall faithfully and diligently perform the duties described on attached Exhibit A and the following described duties on a full-time basis: (a) Devoting Drobny's entire productive time, ability and attention to the business of the Company; and (b) Performing such other duties as the Chief Executive Officer and President of the Company (the "CEO"), shall from time to time specify that are consistent with the duties normally performed by an employee in Drobny's position. 3. Base Compensation. 3.1. Drobny's total compensation ("Base Compensation") under this Agreement, prorated for any partial year, shall be $150,000.00 per year commencing on the Effective Date and ending on the second anniversary of the Effective Date (the "First Half"), and $180,000.00 per year commencing on the expiration of the First Half and continuing until the fourth anniversary of the term of this Agreement (the "Second Half"). The Base Compensation shall be payable biweekly in arrears from the Effective Date, in accordance with and at the same times as the Company's ordinary payroll procedures. 3.2. During the First Half, Drobny may, at his election, receive up to $30,000.00 per year of Base Compensation in the form of shares of the Company's common stock (the "Stock"). During the Second Half, Drobny may, at his election, receive up to $60,000.00 per year of Base Compensation in the form of Stock. Drobny may exercise such option, with respect to any particular semi-annual period (defined as January 1-June 30 and July 1-December 31), by written notice to the Company on or before 5 days before the beginning of such semi-annual period (such exercise, an "Election"). Such notice will specify that portion of his Base Compensation for the upcoming semi-annual period that Drobny elects to receive in the form of Stock. The value of Stock for purposes of this Paragraph shall be determined as follows: (i) If the Stock is not at the time listed or admitted to trading on any stock exchange but is traded in the over-the-counter market, the fair market value shall be the average mean between the highest bid and lowest asked prices (or, if such information is available, the closing selling prices) of one share of the Stock in the over-the-counter market, as such prices are reported by the National Association of Securities Dealers through its NASDAQ system or any successor system, on the first three trading days of the semi-annual period to which the Election relates. If there are no reported bid and asked prices (or closing selling prices) for the Stock on any of the dates in question, then the average mean between the highest bid price and lowest asked prices (or the closing selling price) on the last three preceding dates for which such quotations exist shall be determinative of fair market value. (ii) If the Stock is at the time listed or admitted to trading on any stock exchange, then the fair market value shall be the average closing selling price of one share of Stock on the first three trading days of the semi-annual period to which the Election relates, on the stock exchange determined by the Company, in its reasonable discretion, to be the primary market for the Stock, as such price is officially quoted in the composite tape of transactions on such exchange. If there is no reported sale of Stock on such exchange on the dates in question, then the fair market value shall be the average closing selling prices on the exchange on the last three preceding dates for which such quotations exist. 4. Benefits. Drobny shall be entitled to the following benefits during the term of this Agreement: 4.1. Vacation benefits generally available to other executives of the Company of comparable seniority and rank, accrued over the course of each year in accordance with the Company's policy. 4.2. Reimbursement for reasonable expenses incurred in the proper performance of Drobny's duties under this Agreement and in accordance and consistent with the Company's policy. 4.3. Inclusion in the Company's medical plan for the Company's other employees. 4.4. All benefits generally available to other employees of the Company, including without limitation profit sharing benefits generally made available to other employees of Drobny's rank and seniority. 4.5. Reasonable moving expenses in the event the Company requires Drobny to relocate his residence outside Gulfport, Mississippi. 5. Term. The term of this Agreement shall be four (4) years, commencing on the Effective Date and ending on the fourth anniversary of the Effective Date, unless terminated earlier in accordance with the terms hereof. 6. Termination. At any time that Good Cause (as defined below) exists or has arisen, the Company may, at its election, terminate this Agreement upon 3 days written notice. In the event of such Good Cause termination, Drobny may, at his election, appeal such termination to the Board of Directors of the Company, whose determination shall be final and binding. For purposes of this Agreement, "Good Cause" shall mean the existence or occurrence of any of the following: 6.1. Any neglect or breach of duty by Drobny, or any failure by Drobny to perform, to the reasonable satisfaction of the CEO, such duties as may be delegated to Drobny by the Company from time to time. 6.2. If Drobny is convicted of a felony or files for any protection under the federal bankruptcy laws (or any such proceeding is filed against Drobny and is not dismissed within 90 days of such filing). 6.3. If Drobny commits theft, larceny, embezzlement, fraud, any acts of dishonesty, illegality, moral turpitude or gross mismanagement, as determined in good faith by the CEO, whose determination shall be final and binding. 6.4. If Drobny breaches any obligation set forth in Paragraphs 8, 9, 10 or 11 or materially and repeatedly breaches any other provision of this Agreement. 6.5. If Drobny breaches any term of that certain Asset Purchase Agreement dated November 17, 1997 among MED Associates, Inc., Drobny, Pamela M. Drobny, and the Company. 6.6. The death of Drobny. 6.7. If Drobny becomes materially disabled to such an extent that Drobny is precluded from performing the duties set forth in this Agreement for a period of three (3) months or more within any twelve (12) month period. Disability shall not be proper grounds for termination in the event that such disability arises from injuries received by Drobny while traveling in the scope of his employment. 6.8. If Drobny fails to adhere to any Company policy or any future policy of Company. 7. Representations and Warranties. Drobny hereby represents and warrants that as of the date of execution of this Agreement: (i) this Agreement will not cause or require Drobny to breach any obligation to, or agreement or confidence with, any other person; (ii) except as disclosed in writing by Drobny to the Company prior to the execution of this Agreement, Drobny is not representing, or otherwise affiliated in any capacity with, any other lines of products, manufacturers, vendors or customers of the Company; and (iii) Drobny has not been induced to enter into this Agreement by any promise or representation other than as expressly set forth in this Agreement.

All Proprietary Information developed, created, invented, devised, conceived or discovered by Drobny that are subject to copyright protection are explicitly considered by Drobny and the Company to be works made for hire to the extent permitted by law. Drobny hereby assigns to the Company all of Drobny's right, title and interest in and to the Proprietary Information. Drobny hereby forever fully releases and discharges the Company, any Affiliates of the Company and their respective officers, directors and employees, from and against any and all claims, demands, damages, liabilities, costs and expenses of Drobny arising out of, or relating to, any Proprietary Information. Drobny shall execute any documents and take any action the Company may deem necessary or appropriate to effectuate the provisions of this Agreement, including without limitation assisting the Company in obtaining and/or maintaining patents, copyrights or similar rights to any Proprietary Information assigned to the Company, if the Company, in its sole discretion, requests such assistance.

Drobny acknowledges that the grant of the foregoing power of attorney is coupled with an interest and shall survive the death or disability of Drobny. Drobny shall promptly disclose to the Company, in confidence (a) all Proprietary Information that Drobny creates during the term of this Agreement, and (b) all patent applications filed by Drobny within one year after termination of this Agreement. Any application for a patent, copyright registration or similar right filed by Drobny within one year after termination of this Agreement shall be presumed to relate to Proprietary Information created by Drobny during the term of this Agreement, unless Drobny can prove otherwise. Nothing contained in this Agreement shall be construed to preclude the Company from exercising all of its rights and privileges as sole and exclusive owner of all of the Proprietary Information owned by or assigned to the Company under this Agreement. The Company, in exercising such rights and privileges with respect to any particular item of Proprietary Information, may decide not to file any patent application or any copyright registration on such Proprietary Information, may decide to maintain such Proprietary Information as secret and confidential, or may decide to abandon such Proprietary Information or dedicate it to the public. Drobny shall have no authority to exercise any rights or privileges with respect to the Proprietary Information owned by or assigned to the Company under this Agreement. This Agreement does not apply to any Proprietary Information that qualifies fully under the provisions of California Labor Code Section 2870 or any similar or successor statute. 10. Competition. Drobny acknowledges that this Agreement is being entered in connection with the purchase by the Company of substantially all of the assets of a corporation with respect to which Drobny and his spouse are the sole shareholders. To the extent permitted by applicable law, during the period of time set forth in Paragraph 10.5 below: 10.1. Drobny shall not, directly or indirectly, engage or invest in, own, manage, operate, finance, control, or participate in the ownership, management, operation, or control of, be employed by, associated with, or in any manner connected with, or render services or advice to, any business whose products or activities compete in whole or in part with the products or business of the Company within the world. 10.2. Drobny shall not undertake any employment or activity competitive with the Company's business, including without limitation the inducement or solicitation of the Company's customers, if the duties or work of, in connection with or related to such competitive employment or activity would or might cause Drobny to reveal or use any Confidential Material or Proprietary Information. The restriction set forth in this Paragraph 10.2 shall not be limited to a particular geographical area. 10.3. Drobny shall not, directly or indirectly, either for himself or any other person, (A) induce or attempt to induce any employee of the Company or any Affiliate (as defined below) to leave the employ of such company, (B) in any way interfere with the relationship between the Company or any Affiliate and any employee of such company, (C) employ, or otherwise engage as an employee, independent contractor, or otherwise, any employee of the Company or any Affiliate, or (D) induce or attempt to induce any customer, supplier, licensee, or business relation of the Company or any Affiliate to cease doing business with such company, or in any way interfere with the relationship between any customer, supplier, licensee, or business relation of such company. 10.4. Drobny shall not, directly or indirectly, either for himself or any other person, solicit the business of any person known to Drobny to be a customer of the Company or any Affiliate, whether or not Drobny had business or personal contact with such person, unless Drobny's solicitation of such person is done in connection with a business that is not competitive with that of the Company or any Affiliate. 10.5. The duration of the covenants set forth in this Paragraph 10 shall be the entire term of Drobny's employment with the Company plus a period of two years after the termination of such employment. Drobny agrees that this covenant is reasonable with respect to its duration, geographical area, and scope. Notwithstanding such restriction, Drobny may purchase or otherwise acquire up to (but not more than) three percent (3%) of any class of securities of any enterprise (but without otherwise participating in the activities of such enterprise) if such securities are listed on any national or regional securities exchange or have been registered under Section 12(g) of the Securities Exchange Act of 1934. In the event of a breach by Drobny of any covenant set forth in this Paragraph 10, the term of such covenant will be extended by the period of the duration of such breach, provided, however, that such extension shall be limited to two years. In addition to the Company's right to damages and any other rights it may have, to obtain injunctive or other equitable relief to restrain any breach or threatened breach or otherwise to specifically enforce the provisions of this Paragraph, Drobny agrees that money damages alone would be inadequate to compensate the Company and would be an inadequate remedy for such breach. If a court of competent jurisdiction holds that the obligations of Drobny pursuant to this Paragraph 10 are unenforceable due to the duration, geographical area or scope of this covenant, then such duration, geographical area or scope of this covenant shall be reduced to the least degree necessary to render this covenant enforceable. For purposes of this Agreement, "Affiliate" shall mean any partner, employee, director, shareholder, officer of Company or any person or entity controlled by, controlling, or under common control with, directly or indirectly, the Company. Drobny shall be released from his obligations under this Paragraph 10 upon the occurrence of either of the following events: (a) the material breach by the Company under this Agreement adjudicated as such by a court of competent jurisdiction, or (b) Jon Gilbert and Michael Silverman's termination of their involvement with the Company. 11. Business Opportunities. During the term of this Agreement, if Drobny (or any agent, employee, officer or independent contractor of or retained by Drobny) becomes aware of, or develops, creates, invests, devises, conceives or discovers, any project, investment, venture, business or other opportunity (any of the preceding, an "Opportunity") that is similar to, competitive with, related to or in the same field as the Company or any Affiliate, or any project, investment, venture, or business of the Company or any Affiliate, then Drobny shall so notify the Company immediately in writing of such Opportunity and shall use Drobny's good-faith efforts to cause the Company to have the opportunity to invest in, participate in or otherwise become affiliated with such Opportunity. 12. Survival. The representations, warranties and covenants of Drobny in this Agreement shall survive any termination of this Agreement. 13. Governing Law.
