sufficiency of which are hereby acknowledged, the parties agree as follows:

1.       Term. Turner shall be employed by the Company commencing on the above
         date hereof and terminating two years from such date, unless sooner
         terminated in accordance with the terms of this agreement (such period
         referred to as the Term). There will be two consecutive optional one
         year terms. Each optional year will need the approval of the Company

         of Summit Brokerage Services, Inc.

2.       Positions. During the Term, Turner shall serve as the President and
         Chief Operating Officer of Summit Brokerage Services, Inc. and shall
         perform such duties as shall be delegated to him by the Chief
         Executive Officer and the Board of Directors of that company. Turner
         will be responsible for all day to day operations of the securities
         broker-dealer, all insurance activities inclusive of any separate
         corporate agencies and registered investment advisors. Any
         interference with Turner in carrying out such duties by any other
         employee or officer or Board member or combination thereof who/
         which knowingly may cause Turner or the Company to in any way to
         violate any securities, insurance or investment advisory regulations,
         rules or laws shall be a breach of this contract and shall cause
         immediate payment of any and all compensation and stock options to
         Turner. After such payment, Turner shall render a written resignation
         resigning all positions with any and all affiliated companies of
         Summit Brokerage Services, Inc. or its successors.

3.       Compensation. Turnover shall receive an initial annual salary of
         $100,000 of which $1,667 per month shall be deferred until the last

         will be made to Turner for $11,669; 15,000 shares of company stock
         for year one and 15,000 shares of

         stock for year two. This salary will be increased in the second year
         by five percent (5%) and each year thereafter for each additional
         year. Turner shall receive prerequisites as may be directed by the
         Board of Directors but shall be no less than three weeks vacation in
         year one and four weeks vacation in year two (any vacation time
         remaining at the end of each year shall be paid to Turner at 1 1/2
         times its value) health and life insurance coverage for Turner and his
         spouse and a $200/month car allowance.

         the company will pay all such relocation expenses inclusive of any
         realtor's fees in the sale of Turner's current residence plus all
         closing costs on the purchase of a new residence. Additionally all
         interim housing expenses between such relocation and the location in a
         new residence.

5.       Stock Options. On the date hereof the Company grants to Turner 100,000
         options (50,000 options each year of the term). Each year of

         options exercisable for shares of the Company's common stock. The
         exercise price for all options shall be $2.50. Exercise of the options
         may be done on a cashless basis through the company or through any
         securities broker dealer.

6.       Vesting of Options. The above options shall vest as granted. Should a
         change of control of the Company take place during the term, all
         options will automatically be 100% vested and thereby exercisable. The
         expiration date of each option shall be one year after the end of the
         Term or after Turner's last year of employment with the firm.

7.       Change of Control. In the event Turner is terminated in connection

         position is terminated or changed.

8.       Benefit Plans. Turner shall be entitled to participate in the
