Employee to the fullest extent permitted by The Companies Act of the
Commonwealth of the Bahamas, as amended from time to time, for all amounts

and attorney's fees) incurred or paid by the Employee in connection with any
action, suit, investigation or proceeding arising out of or relating to the
performance by the Employee of services for, or the acting by the Employee as a

unreasonable terms.

7. Stock Options: The Employer hereby grants to the Employee options (the "Stock
Options") to purchase 2,500,000 shares of the common stock of the Employer (the
"Options Shares") exercisable over a six-year period regardless of whether the
Employee is working for, or employed by the Employer. Said Stock Options shall
be assignable and transferrable without any limitations whatsoever. The Employer
and Employee hereby agree that as of the date of this Agreement, all 2,500,000
shares shall be and are hereby declared to be vested and immediately
exercisable. The exercise price (the "Option Price") for the Option Shares shall
be Two Dollars and Twenty-Five ($2.25) cents (U.S. Funds) per share, which
Option Price is the closing price of the Employer's common stock as of the date
of this Agreement, and is the fair market value of the Option Shares. Stock
Options are cumulative. The Stock Options shall be exercisable from time to time
in whole or in part without affecting the remainder of the Stock Options during
the term of the exercisability and any renewal or extension thereof and for six
years from the date of this Agreement.

7.1 Exercise of Stock Options: Stock Options may be exercised by written notice
directed to the Employer or such other person as may be designated by the
Employer accompanied by a check payable to the Employer in payment of the option
price for the option shares. The Employer shall make immediate delivery of the
purchased option shares, fully paid and nonassessable, registered in the name of
the Employer subject to a restrictive legend set forth on the purchased Option
Shares certificate as follows:

The shares of stock represented by this Certificate have not been registered
under the Securities Act of 1993, as amended ("Act"), or the securities laws of
any other jurisdiction and may not be sold, transferred, pledged, hypothecated
or otherwise disposed of in any manner unless they are registered under such Act
and the securities laws of any applicable jurisdictions or unless pursuant to an
exemption therefrom.

7.2 Reclassification, Consolidation or Merger: If and to the extent that the
number of issued and outstanding shares of common stock of the Employer shall be
increased or reduced by a change of par value, split-up, reclassification,
distribution of a dividend payable in stock, issuance of convertible
debentures, warrants or similar transactions, the number of shares subject to 
the Stock Options and the Option Price per share shall be proportionately
adjusted to protect the Employee from dilution. If the Employer is reorganized
or consolidated or merged with another corporation, the Employee shall be
entitled to receive options covering shares of such reorganized, consolidated,
or merged company in the same proportion, at an equivalent price, and subject
to the same conditions. For purposes of the preceding sentence, the excess of
the aggregate fair market value of the shares subject to the option immediately
after the reorganization, consolidation or merger over the aggregate option
price of such shares shall not be more than the excess of the aggregate fair
market value of all shares subject to the Stock Options immediately before such
reorganization, consolidation or merger over the aggregate option price of such
shares, and the new option or assumption of the old Stock Options shall not
give Employee additional benefits which he did not have 




                                      3
<PAGE>   4

under the old Stock Options, or deprive him of benefits which he had under the
old Stock Options. If there is a purchase of stock of the Employer by a party
who is not an affiliate of the Employer that causes a change in control of the
Employer (as defined hereinafter), the Employer or purchasing entity shall
purchase the Options Shares which have not been registered on the same basis as
all other shares.

8. Death During Employment: If Employee dies during the Term of this Agreement,
the Employer will pay to the Employee's surviving spouse the Base Salary which
would otherwise be payable to the Employee for a period of not less than six
months after the date in which Employee's death occurred. Furthermore, the
Employee's surviving spouse or the Employee's estate, if otherwise provided,
shall obtain all rights in vested stock options plus the right to exercise the
stock options on 100% of the non-vested stock options, together with the sales
rights of such stocks and/or stock options that have been granted to the
Employee hereunder.

9. Disability: If Employee suffers from a disability as hereinafter defined, his
employment hereunder may, after notice is hereinafter provided, at the option of
the Employer, be deemed terminated. In such event, the Employer will pay the
Employee the Base Salary, Bonus, and all fringe benefits otherwise payable to
him for a period of one year after the date upon which the Board deems the
Employee to be disabled hereunder (the "Disability Wage"). The Employer shall
have the right, however, to set off against the amount of the Disability Wage
payable to the Employee all amounts which may be received by Employee during
such one-year period pursuant any disability insurance which the Employee may
have. The Employer shall have no further wage obligations to the Employee or his
estate except as otherwise provided in this Agreement. For this purpose, the
terms "disability" and "disabled" are defined as Employee's inability for a
period of 180 days in a 360 day period to perform his duties under this
Agreement. If there is a dispute as to the existence of the Employee's
disability, then said dispute shall be submitted to binding arbitration as
provided hereafter.

including but not limited to, marijuana, cocaine, heroin, and all other illegal
