Dear

I
am pleased to confirm that the Company has selected you as a Participant in the Peregrine Systems, Inc. Retention Bonus Plan (the "Plan"). The Plan is designed to aid in the
retention of the Company's most crucial employees in the event of a Change of Control of the Company by providing for the award of retention bonuses.

General terms

Your Retention Bonus Amount under the Plan is $250,000. This is the amount you are eligible to receive under the Plan so long as you remain employed with the
Company through the six-month anniversary of the consummation of a Change in Control of the Company or
if your employment is terminated in connection with, in anticipation of or following a Change of Control under certain circumstances as described in this Notice of Participation and the Plan.

The
basic terms of your participation in the Plan are set forth in this Notice of Participation, but other important terms and conditions are described in the Plan. We encourage you to
carefully review the Plan, a copy of which is included with this Notice. Capitalized words in this Notice of Participation which are not defined herein are defined in the Plan. In the event of any
conflict between the provisions of this Notice of Participation and the provisions of the Plan, the terms of the Plan shall control. This letter constitutes the Notice of Participation called for in
the Plan.

Payment Terms

In accordance with Section 4(a)(i) of the Plan, except as set forth below, your Retention Bonus Amount shall be payable (a) fifty percent
(50%) upon the consummation of a Change of Control, and (b) fifty percent (50%) upon the date that is six months after the consummation of a Change of Control. If any scheduled payment date is
not a business day, the applicable payment shall be made on the first business day following the applicable payment date.
