                FY05 EXECUTIVE ANNUAL INCENTIVE COMPENSATION PLAN

JOB CATEGORY:              PRESIDENT AND CHIEF OPERATING OFFICER, GRADE 22

Purpose:                   Provide critical focus on specific, measurable goals
                           and to provide incentive compensation upon their
                           attainment.

Bonus Target:              The target incentive for this executive position is
                           80% of the annual base salary. Annual base salary
                           will be reviewed and established at the beginning of
                           each fiscal year. Bonuses will be paid based on
                           actual annual base salary earnings from time of
                           eligibility in the Executive Incentive Plan through
                           March 31, 2005.

Bonus Payments:            The incentive will be paid once annually. Payment
                           will be made within six weeks of the financial close
                           of the fiscal year. Any payments made under this plan
                           are at the sole discretion of the Board of Directors.

Components:                Two metrics will be used to determine the annual
                           bonus payment:

<TABLE>
<CAPTION>
METRIC                               WEIGHTING
------                               ---------
<S>                                  <C>
Corporate Revenue                       50%
Corporate Earnings per Share            50%
</TABLE>

Achievement Schedule:      Each metric has a minimum performance threshold that
                           must be exceeded before that portion of the metric
                           will be paid. Payment for corporate results is
                           uncapped.

Pro-ration:                The Annual Incentive Plan calculation will be based
                           on all eligible base salary earnings for the year,
                           and will be pro-rated based on the number of weeks of
                           participation.

Eligibility:               The Plan participant must be a regular, full-time
                           employee at the end of the fiscal year in order to
                           participate. If the company grants an interim payment
                           for any reason, the participant must be a regular,
                           full-time employee at the end of that performance
                           period in order to receive such payment. A plan
                           participant who leaves before the end of the fiscal
                           year will not receive the end of the fiscal year
                           payment under the Plan or any pro-ration thereof.

Exchange Rates:            The Corporate Performance metrics will not be
                           adjusted for any fluctuating currency exchange rates.
                           Actual growth numbers will be used.

Acquisition:               In the event of an acquisition or purchase of
                           products or technology, the Revenue Growth and
                           Earnings per Share numbers will be adjusted to
                           reflect the change and are to be approved by the
                           Compensation Committee of the Board of Directors.

Plan Provisions:           This plan supersedes any previous incentive or bonus
                           plan that may have been in existence. Those plans are
                           null and void with the issuance of this plan for
                           FY05.

                           Participating in the plan for FY05 does not guarantee
                           participation in future incentive plans. Plan
                           structures and participation will be determined on a
                           year to year basis and are guidelines only.

                           The Board of Directors reserves the right to alter or
                           cancel any or all such Plans for any reason at any
                           time.

                           The Board of Directors, acting on behalf of the
                           shareholders in their best interests, reserves the
                           right to exercise their own judgment with regard to
                           company performance in light of uncontrollable events
                           including, but not limited to, currency fluctuations,
                           business goal modification, and management changes.
