Dear
Russ:

On
behalf of Peregrine Systems, Inc. ("PSI") we would like to offer you the position of Senior Vice President, Strategic Initiatives reporting to John Mutch, President and Chief
Executive Officer, effective on or about August 2, 2004 ("Commencement Date"), subject to the following terms and conditions:

1.BASE SALARY.Your starting salary will be $11,041.67 per semi-monthly pay period effective with
your Commencement Date.

2.EMPLOYMENT TERM.The term of your employment under this letter agreement (the "Employment Term") will begin
on your Commencement Date and end when it is terminated in accordance with Section 6.

3.BONUS.Additionally, you will be eligible to participate in the Management Incentive Compensation Plan (MICP)
with an annual target of $50,000. This bonus is paid semi-annually, prorated from your hire date. A copy of the summary plan description is attached.

4.BENEFITS.You will be eligible to participate in PSI's employee benefit plans of general application,
including, without limitation, those plans covering medical, disability and life insurance in accordance with the rules established for individual participation in any such plan and under applicable
law. You will be eligible for paid time off ("PTO") in accordance with PSI policies in effect during the term of this letter agreement and will receive such other benefits as PSI generally provides to
its other employees of comparable position and experience.

5.OPTIONS.Subject to formal approval by the Compensation Committee of the Board of Directors, you will be
granted an option to purchase up to 65,000 shares of PSI common stock, subject to execution of this letter agreement and your executing a stock option agreement consistent with the terms and
conditions of the 2003 Equity Incentive Plan (the "Plan"). The date of grant of the Options will be the Commencement Date or date of formal approval by the Compensation Committee, whichever is later
(the "Grant Date"), and the exercise price per share of the Options will be the fair market value of PSI's common stock on the Grant Date as determined under the Plan. The right to exercise the
Options will vest 25% after the first 12 months, and in 36 equal monthly installments thereafter. Notwithstanding any provisions of the Plan or the stock option grant agreement evidencing the
Options to the contrary, if you terminate your employment with PSI for Good Reason (as defined below) or are subject to a Termination without Cause (as defined below), in each case in connection with
or within twelve (12) months after the occurrence of a Change in Control (as defined in the Plan), 100% of the portion of this Option which would otherwise be unvested as of the date of your
termination under the provisions set forth in the stock option grant agreement shall become vested as of the date of your termination.

6.TERMINATION.Peregrine Systems is an "at-will" employer, and as such the employer/employee
relationship is subject to termination by either party at any time with or without cause as follows:



---





For
purposes of this letter agreement, the term "Disability" shall mean your inability to substantially perform your job responsibilities for a period of 180 consecutive days or 180 days in the
aggregate in any 12-month period. For purposes of this letter agreement, "Cause" means (i) gross negligence or willful misconduct in the performance of your duties to PSI (other
than as a result of a Disability); (ii) repeated and continued failure to perform your duties and responsibilities as a PSI employee (including, but not limited to your compliance with any
written policy of PSI) in good faith after having a reasonable opportunity to cure such failure; (iii) commission of any act of fraud or violation of any federal or state securities laws or any
SEC rules and regulations with respect to PSI; or (iv) conviction of a felony or a crime involving moral turpitude if such felony or crime could cause material harm to the business affairs or
reputation of PSI in the reasonable determination of PSI's Board of Directors. No act or failure to act by you shall be considered "willful" if done or omitted by you in good faith with reasonable
belief that your action or omission was in the best interests of PSI. "Good Reason" shall mean (i) a significant reduction of your duties, title, position, or responsibilities relative to your
duties, title, position, or responsibilities in effect immediately prior to such reduction (including a material change in your reporting structure which shall include, but not be limited to, your no
longer reporting to the President and CEO) that is effected without your consent or agreement; (ii) a substantial reduction without good business reasons of the facilities and perquisites
available to you immediately prior to such reduction if such reduction is effected without your consent or agreement; (iii) a reduction by PSI in your Base Salary and Target Bonus in effect
immediately prior to such reduction if such reduction is effected without your consent or agreement (other than any such reduction that is effected on substantially a company-wide basis in order to
reduce PSI's operating expenses); (iv) the relocation of your primary office at PSI to a facility or location that is more than fifty (50) miles away from your primary office location
immediately prior to such relocation, if such relocation is effected without your consent or agreement.

7.SEPARATION BENEFITS.Upon termination of your employment with PSI for any reason, you will receive payment
for all salary and unpaid PTO (paid time off) accrued to the date of your termination of employment. Your benefits will be continued under PSI's then existing benefit plans and policies for
so long as provided under the terms of such plans and policies and as required by applicable law. Under certain circumstances, you will also be entitled to receive severance benefits as set forth
below, but you will not be entitled to any other compensation, award or damages with respect to your employment or termination.

8.RELEASE.You agree that the severance payments you may be entitled to upon Termination for Good Reason,
Termination without Cause or upon a Change of Control (assuming your employment is terminated in connection with or within twelve (12) months following such Change of Control) will not apply
unless you (i) have executed a general release (in a form customarily used by PSI) of all known and unknown claims that you may then have against PSI and/or persons or entities affiliated with
PSI, (ii) have agreed not to prosecute or bring any legal action or other proceeding based upon any of such claims and (iii) have agreed to provide reasonable transition assistance to
PSI (or the surviving corporation) for three (3) months following termination of employment.

9.CONFIDENTIALITY, NONSOLICITATION.In light of the fact that the confidential information that you have
acquired, and will acquire, is inextricably bound with your knowledge regarding the conduct of PSI's business activities and that therefore you would necessarily use confidential information if you
were to compete with PSI, you agree that during the Employment Term, and for a period of one (1) year thereafter, you will not provide any services, whether as an officer, director, proprietor,
employee, partner, consultant, advisor, agent, sales representative or otherwise, nor will you own beneficially securities of any entity (except that, in the case of any entity whose equity securities
are publicly-held, you may beneficially own up to 2% of the outstanding equity securities of such entity or any mutual fund holding securities of such entity) that, directly or indirectly,
competes with any of PSI's present or future (up to the date of termination) business activities. You further agree that in light of the nature of PSI's business, and the life-cycle of
product development, the one-year period provided for above shall apply in regardless of the nature or reason for your termination and that it is reasonable and necessary in order to
protect the confidential, proprietary and trade-secret information that you will acquire as a result of being Senior Vice President, Strategic Initiatives of PSI. Notwithstanding the foregoing, such
restrictions shall not preclude you from providing any services to a distinct business unit of an entity if such unit does not compete with PSI's business activities, regardless of whether any other
distinct business unit of such entity competes with PSI's business activities. You also, further and independently, agree that during your employment with PSI, and for a period of one (1) year
after termination of your employment with PSI, you will not for any reason, whether directly or indirectly: (a) solicit, recruit, take away or attempt to take away, any employee or consultant
of PSI or any of its affiliates, or induce (or attempt to induce) any employee or consultant of PSI or any of its affiliates to terminate his or its employment or services with PSI or any of PSI's
affiliates; or (b) directly or indirectly, solicit any customer of PSI or any of its affiliates or induce any customer of PSI or its affiliates to terminate its relationship with PSI or any PSI
affiliate; provided, however, that this non-solicitation provision shall not prevent you from hiring any employee or consultant of PSI or any of its affiliates that you can demonstrate
either (i) approached you independently without any prior direct or indirect solicitation or encouragement by you or on your part, or (ii) replied to a solicitation

to the general public without any direct or indirect solicitation or encouragement by you or on your part.

without reference to its conflict of laws provisions.

all purposes of this letter agreement, the term "PSI" shall include any successor to PSI's business and/or asserts which becomes bound by this letter agreement.
