COMPENSATION
TARGET:           $140,000 for the 6 month period, including base salary

BONUS
GUARANTEE:        Guaranteed bonus of $8,833 per month through November 30, 1997

GROSS MARGIN:     Bonus target of $10,000. Fiscal year end bonus paid at the
rate of $5,000 if gross margin exceeds 10%, $10,000 if gross margin exceeds 15%,
or $15,000 if gross margin exceeds 20%. "Gross margin" is defined as booked
revenue arising from customers in the Territory, less all direct costs and cost
of sales inclusive of physical product delivery expense and third party
royalties. For the fiscal year ending March 31, 1998, the gross margin
definition excludes costs for Corporate and European marketing, European client
support and European finance & administration.

COMMISSION:       Target of $25,334 based on December 1997 through March 1998
revenues in the Territory of $2,840,000. This commission plan will apply
effective with the close of

<PAGE>





business in November 1977 with the first payment to occur on December 31,1997.
Commissions paid at the rate of .4% when trailing 3 months quota performance is
below 80%, .9% when trailing 3 months quota performance is between 80-120%, and
1.4% when trailing 3 months quota performance is over 120%. Commission shall be
determined on a rolling 3 month basis by using the two prior months and the
month just completed to determine the commission rate to apply to the just
completed month's revenue. For the purpose of calculating the Commission due for
the month of November, the actual Showcase Revenue of $695,000 shall also be
used as the quota for the month of September.

"Revenue" is defined as net product revenue booked after payment of sales and/or
finders fees to third parties, services revenues recognized for work performed
by Showcase personnel plus the net of any third party service revenues invoiced
by Showcase after deducting the third party charges for the services rendered in
the generation of such revenues, plus all maintenance/sup port fees recognized.

Miscellaneous: All interpretations of this plan are to be made by the Chairman
of the Company. The Company retains the right to change this plan at any time
should inaccuracies or errors be discovered that are inconsistent with the
intent of the Company to pay bonuses consistent with performance achievement.
Bonus payments may be withheld or debited in the event that Showcase is unable
to collect payment from the customer within a reasonable timeframe. Similarly,
bonus payment may be withheld or debited in the event the Executive fails to
apply sound ethical judgement and good business practice in any transaction,
including compliance with pre-authorised levels or discount and fair
representation of product attributes.
