Exhibit 10.20 - 1998 OFFICER BONUS PLAN

The Company has adopted a 1998 Officer Bonus Plan under which all executive 
officers are awarded cash bonuses based on the Company's operating results.  
The respective bonus payments are calculated with reference to the actual 
pre-tax income (and revenue for the Senior Vice President, Worldwide Sales and 
Customer Support) results as measured against the 1998 Operating Plan presented 
and approved at the Board of Directors meeting on January 26, 1998.  The 
pre-tax income level is measured prior to any accruals reflecting the Company's 
bonus payments.  No profit bonus will be paid for achievement of 50% or less of 
the planned objective.  At 100% achievement, 100% of the profit bonus will be 
paid.  At 150% achievement, 200% of the profit bonus will be awarded.  For 
results between 50% and 100% and between 100% and 150%, the profit bonus will 
scale in a linear fashion (e.g., 50% profit bonus at 75% achievement of plan 
and 150% profit bonus at 125% of plan).

The "On-Plan" revenue commissions for the Senior Vice President, Worldwide 
Sales and Customer Support, shall be measured against the revenue (excludes 
Worldwide Service division revenue for which the Senior Vice President is not 
responsible).
