                               STOCK OPTION PLAN
 
     It is currently the Company's policy that all full time key employees be
considered annually for the possible grant of stock options, depending upon
employee performance. The criteria for the awards are experience, uniqueness of
contribution to the Company and level of performance shown during the year.
Stock options are intended to improve loyalty to the Company and help make each
employee aware of the importance of the business success of the Company.
 
     As of December 31, 1997, the Company has 161,100 options to purchase shares
of the Company's Common Stock outstanding under the 1996 Plan (as defined
below). During 1997, the Company also granted to its Vice President, Mr. Arik
Shavit, warrants to purchase up to 217,473 shares of its Common Stock, which
warrants vest over a four year period. See 'Summary Compensation Table' and
'Employment/Consulting Contracts.' A summary of the established stock option
plan is as follows:
 
     The Company's Incentive & Non-Qualified Stock Option Plan, adopted in 1996,
(the '1996 Plan') provides for the grant to qualified employees (including
officers and directors) of the Company of options to purchase shares of Common
Stock. A total of 450,000 shares of Common Stock have been reserved for issuance
upon exercise of stock options granted under the 1996 Plan. The 1996 Plan is
administered by the Board of Directors or a committee of the Board of Directors
whose members are not entitled to receive options under the Plan (excluding
options granted exclusively for directors fees). The Board or the Board
committee has complete discretion to select the optionee and to establish the
terms and conditions of each option, subject to the provisions of the Plan.
Options granted under the Plan may or may not be 'incentive stock options' as
defined in Section 422 of the Internal Revenue Code ('Incentive Options')
depending upon the terms established by the Board at the time of grant, but the
exercise price of options granted may not be less than 100% of the fair market
value of the
 
                                       4

<PAGE>

Common Stock as of the date of grant (110% of the fair market value if the grant
is an Incentive Option to an employee who owns more than 10% of the outstanding
Common Stock). Options may not be exercised more than 10 years after the grant
(five years if the grant is an Incentive Option to any employee who owns more
than 10% of the outstanding Common Stock). Options granted under the Plan are
not transferable and may be exercised only by the respective grantees during
their lifetimes or by their heirs, executors or administrators in the event of
death. Under the 1996 Plan, shares subject to canceled or terminated options are
reserved for subsequently granted options. The number of options outstanding and
the exercise price thereof are subject to adjustment in the case of certain
transactions such as mergers, recapitalizations, stock splits or stock
dividends.
 
     As of the date of this Prospectus, the Company has granted options for an
aggregate of 161,100 shares of Common Stock.
