          AGREEMENT made as of the 25th day of August, 1998, by and between
Cyber Mark International Corp., a Delaware corporation ("Company"), and Joseph
Byck ("Employee").

          WHEREAS, the Company and Employee have entered into an Employment
Agreement of even date herewith pursuant to which Employee will be employed by
the Company ("Employment Agreement");

          WHEREAS, on August 25, 1998 ("Grant Date"), the Board of Directors of
the Company ("Board") authorized the grant to the Employee of an option
("Option") to purchase an aggregate of 400,000 shares of the authorized but
unissued Common Stock of the Company ("Common Stock"), conditioned upon the
Employee's acceptance thereof upon the terms and conditions set forth in this
Agreement; and

          WHEREAS, the Employee desires to acquire the Option on the terms and
conditions set forth in this Agreement;

          IT IS AGREED:

          1. Grant of Stock Option. The Company hereby grants the Employee the
Option to purchase all or any part of an aggregate of 400,000 shares of Common
Stock ("Option Shares") on the terms and conditions set forth herein.

          2. Non-Incentive Stock Option. The Option represented hereby is not
intended to be an Option which qualifies as an "Incentive Stock Option" under
Section 422 of the Internal Revenue Code of 1986, as amended.

          3. Exercise Price. The exercise price of the Option is as set forth in
paragraph 4 hereof, subject to adjustment as hereinafter provided.

          4. Exercisability. This Option is exercisable as follows: (i)
commencing December 31, 1998 and ending December 31, 2001, this Option may be
exercised for up to 200,000 shares of Common Stock at US$.50 per shares; (ii)
commencing December 31, 1999 and ending December 31, 2002, this Option may be
exercised for up to 100,000 additional shares of Common Stock at US$1.00 per
share; and (iii) commencing December 31, 2000 and ending December 31, 2003, this
Option may be exercised for up to 100,000 additional shares of Common Stock at
US$1.25 per share. The period during which a portion of the Option is
exercisable is referred to as the Exercise Period.

          5. Effect of Termination of Employment. The termination of the
employment of Employee will have no effect on the exercisability of a portion of
this Option once it becomes exercisable. If Employee's employment is terminated
before a portion of this Option is exercisable, that portion of the Option will
terminate and be of no further effect.

          6. Withholding Tax. Not later than the date as of which an amount
first becomes includible in the gross income of the Employee for Federal income
tax purposes with respect to the Option, the Employee shall notify the Company
of the amount and, to the extent required, pay to the Company, or make
arrangements satisfactory to the Company regarding the payment of, any Federal,
state, local and other taxes of any kind required by law to be withheld or paid
with respect to such amount. The obligations of the Company under this Agreement
shall be conditional upon such pay ment or arrangements with the Company and the
Company shall, to the extent permitted by law, have the right to deduct any such
taxes from any payment of any kind otherwise due to the Employee from the
Company.

          7. Adjustments. In the event of any stock dividend, forward stock
split, reverse stock split, or other recapitalization of the Company which
affects the number of outstanding shares of Common Stock, the Company shall
proportionally adjust the number and kind of Option Shares and the exercise
price of the Option in order to prevent the dilution or enlargement of the
Employee's proportionate interest in the Company and Employee's rights hereunder


                                        2


<PAGE>


immediately prior to the stock dividend, stock split, reverse stock split or
recapitalization, provided that the number of Option Shares shall always be a
whole number.

          8. Method of Exercise.

             8.1.     Notice to the Company.  The Option shall be exercised in
whole or in part by written notice in substantially the form attached hereto as
Exhibit A directed to the Company at its principal place of business accompanied
by full payment as hereinafter provided of the exercise price for the number of
Option Shares specified in the notice.

             8.2.     Delivery of Option Shares.  The Company shall deliver a
certificate for the Option Shares to the Employee as soon as practicable after
payment therefor.

             8.3.     Payment of Purchase Price.

                      8.3.1.  Payment.  The Employee shall make payments by wire
transfer, certified or bank check or personal check, in each case payable to the
order of the Company; the Company shall not be required to deliver certificates
for Option Shares until the Company has confirmed the receipt of good and
available funds in payment of the purchase price thereof.

                      8.3.2.  Payment of Withholding Tax.  Any required
withholding tax shall be paid in cash in accordance with Sections 8.3.1.

          9. Nonassignability. The Option shall not be assignable or
transferable except by will or by the laws of descent and distribution in the
event of the death of the Employee. No transfer of the Option by the Employee by
will or by the laws of descent and distribution shall be effective to bind the
Company unless the Company shall have been furnished with written notice thereof
and a copy of the will and such other evidence as the Company may deem necessary
to establish the validity of the transfer and the acceptance by the transferee
or transferees of the terms and conditions of the Option.

         exemption may require a holding period of not less than one year after

                                        4


<PAGE>


          or may possess such information or can acquire it without unreasonable
          effort or expense necessary to verify the accuracy of the information
          obtained pursuant to this clause;

               (d)  he is aware that the Company shall place stop transfer
          orders with its transfer agent against the transfer of the Option
          Shares in the absence of registration under the 1933 Act or an
          exemption therefrom as provided herein; and

               (e)  The certificates evidencing the Option Shares may bear the
         following legends:

         "The shares represented by this certificate have been
         acquired for investment and have not been registered
         under the Securities Act of 1933. The shares may not
         be sold or transferred in the absence of such
         registration or an exemption therefrom under said
         Act."

         "The shares represented by this certificate have been

         with the Company, and may not be trans ferred,
         pledged or disposed of except in accordance with the
         terms and conditions thereof."

          12. Restriction on Transfer of Stock Option Agreement and Option
Shares. Anything in this Agreement to the contrary notwithstanding and in
addition to the provisions of Section 11 of this Agreement, the Employee hereby
agrees that he shall not sell, transfer by any means or otherwise dispose of the
Option Shares acquired by him without registration under the 1933 Act, or in the
event that they are not so registered, unless (i) an exemption from the 1933 Act
registration requirements is available thereunder, and (ii) the Employee has
furnished the Company with notice of such proposed transfer and the Company's
legal counsel, in its reasonable opinion, shall deem such proposed transfer to
be so exempt.

          13. Registration Right. The Company shall promptly (time not being of
the essence) file a Registration Statement on Form S-8 (or successor form) to
register the Option Shares for issuance to Employee at such time as is permitted



                                        5

agreement between the parties with respect to the subject matter hereof. This
Agreement may not be amended except by writing executed by the party to be
