                                                               EXECUTION VERSION

                                ESCROW AGREEMENT


         THIS ESCROW AGREEMENT ("Escrow Agreement"), dated as of November __,
2002, is entered into by and among BMC Software, Inc., a Delaware corporation
(the "Purchaser"), Peregrine Systems, Inc., a Delaware corporation (the
"Stockholder"), and JPMorgan Chase Bank, a New York State bank with an office in
Houston, Texas, as escrow agent ("Escrow Agent"). Defined terms used but not
otherwise defined herein shall have the meanings set forth in the Acquisition
Agreement (the "Acquisition Agreement") dated as of September 20, 2002, among
the Purchaser, the Stockholder and Peregrine Remedy, Inc., a Delaware
corporation (the "Company").

         WHEREAS, the parties to the Acquisition Agreement have agreed to
establish an escrow fund, consisting of a portion of the Cash Purchase Price,
from which any amount payable to the Purchaser pursuant to Section 2.4 or
Article VIII of the Acquisition Agreement may be satisfied; and

         WHEREAS, the Escrow Agent has agreed to act as the agent and custodian
for the Escrow Funds (defined below) for the benefit of the parties to the
Acquisition Agreement.

         NOW, THEREFORE, in consideration of the foregoing and of the mutual
agreements, provisions and covenants contained in this Escrow Agreement and the
Acquisition Agreement, the parties hereby agree as follows:

                                    ARTICLE 1
                             ESTABLISHMENT OF ESCROW

         (a) The Purchaser and the Stockholder each hereby appoint the Escrow
Agent to act as agent and custodian for the Escrow Funds for their respective
benefit pursuant to the terms of this Escrow Agreement, and the Escrow Agent
hereby accepts such appointment pursuant to such terms.

         (b) Pursuant to the terms of Section 2.3(c) of the Acquisition
Agreement, the Purchaser will cause to be delivered to, and directly deposited
with, the Escrow Agent $10,000,000 in cash. Such deposit, with all interest and
other earnings accumulated thereon, less any distributions made pursuant to this
Escrow Agreement shall be referred to herein as the "Escrow Funds."

         (c) Except as otherwise expressly provided herein, the Escrow Funds
shall be held exclusively for the benefit of the Stockholder, and the
Stockholder shall have full and exclusive equitable title and entitlement to the
Escrow Funds.

         (d) The Escrow Funds shall be retained, managed and disbursed by the
Escrow Agent subject to the terms and conditions of this Escrow Agreement.




                                    ARTICLE 2
                         INVESTMENT OF THE ESCROW FUNDS

         (a)  The Escrow Agent shall invest and reinvest the Escrow Funds in the
JPMorgan Prime #830 Money Market Fund, unless otherwise instructed in writing by
the Purchaser and the Stockholder. Such written instructions, if any, referred
to in the foregoing sentence shall specify the type and identity of the
investments to be purchased and/or sold and shall also include the name of the
broker-dealer, if any, which the Purchaser and the Stockholder direct the Escrow
Agent to use in respect of such investment, any particular settlement procedures
required, if any (which settlement procedures shall be consistent with industry
standards and practices), and such other information as the Escrow Agent may
require. The Escrow Agent shall not be liable for failure to invest or reinvest
funds absent sufficient written direction. Unless the Escrow Agent is otherwise
directed in such written instructions, the Escrow Agent may use a broker-dealer
of its own selection, including a broker-dealer owned by or affiliated with the
Escrow Agent or any of its affiliates. The Escrow Agent or any of its affiliates
may receive compensation with respect to any investment directed hereunder. It
is expressly agreed and understood by the parties hereto that the Escrow Agent
shall not in any way whatsoever be liable for losses on any investments,
including, but not limited to, losses from market risks due to premature
liquidation or resulting from other actions taken pursuant to this Escrow
Agreement.

         (b)  Receipt, investment and reinvestment of the Escrow Funds shall be
confirmed by the Escrow Agent as soon as practicable by account statement, and
any discrepancies in any such account statement shall be noted by the Purchaser
and the Stockholder to the Escrow Agent within 30 calendar days after receipt
thereof. Failure to inform the Escrow Agent in writing of any discrepancies in
any such account statement within said 30-day period shall conclusively be
deemed confirmation of such account statement in its entirety. For purposes of
this paragraph, each account statement shall be deemed to have been received by
the party to whom directed on the earlier to occur of (i) actual receipt thereof
and (ii) three "Business Days" (hereinafter defined) after the deposit thereof
in the United States Mail, postage prepaid. The term "Business Day" shall mean
any day of the year, excluding Saturday, Sunday and any other day on which
national banks are required or authorized to close in Houston, Texas.

                                    ARTICLE 3
                          DISBURSEMENT OF ESCROW FUNDS

         The Escrow Agent is hereby authorized and directed to make
disbursements of the Escrow Funds pursuant to any of the following:

         (a)  If the Purchaser believes that it is entitled pursuant to Section
2.4 or Article VIII of the Acquisition Agreement to payment of any amount from
the Stockholder or the Company (a "Claim"), the Purchaser may at any time and
from time to time prior to 5:00 p.m. Houston time on the first anniversary of
the Closing Date (the "Expiration Date") deliver a written notice of such Claim
("Notice of Claim") to the Escrow Agent with a copy to the Stockholder stating
the amount of such Claim, briefly describing the basis for the Claim and stating
the date that the Stockholder is deemed to have received notice of such Claim
from the Purchaser pursuant to the Acquisition Agreement (the "Claim Notice
Date"). If the Escrow Agent receives a Notice of Claim from the Purchaser prior
to the Expiration Date, unless prior to 5:00 p.m. Houston time on

                                       2


the 20th day following the Claim Notice Date (the "Claim Notice Period") the
Escrow Agent receives from the Stockholder a written notice of objection (the
"Notice of Objection") to all or any part of such Claim, which Notice of
Objection shall: (i) attach a copy of such Notice of Claim, (ii) state that, in
the good faith opinion of the Stockholder, the Claim described in the Notice of
Claim is invalid (either in whole or in part, and if the Stockholder objects in
part shall specify, including the dollar amount, that portion of the related
Claim that the Stockholder does not dispute) under the terms of either Section
2.4 or Article VIII of the Acquisition Agreement, (iii) give the reasons for the
alleged invalidity, and (iv) state that, based on such alleged invalidity, the
Stockholder objects to the payment of all or such portion of the Escrow Funds to
the Purchaser, the Escrow Agent shall, after expiration of the Claim Notice
Period and upon receipt of written instructions signed by the Purchaser, release
to the Purchaser a cash amount from the Escrow Fund equal to the lesser of (i)
the amount so claimed in such Notice of Claim and (ii) the remaining amount of
the Escrow Funds.

         (b)  If, within the Claim Notice Period, the Escrow Agent receives a
Notice of Objection from the Stockholder as aforesaid, the Escrow Agent shall:

              (i) upon receipt of written instructions signed by the Purchaser,
         release to the Purchaser a cash amount from the Escrow Fund equal to
         the lesser of (x) such portion (if any) of the amount claimed in the
         Notice of Claim as is not disputed by the Stockholder in the Notice of
         Objection and (y) the remaining amount of the Escrow Funds; and

              (ii) hold the disputed amount of such Claim to be distributed or
         otherwise dealt with in accordance with the terms of this Escrow
         Agreement, including as provided in paragraphs (c), (d) and (e) below.

         (c)  Upon receipt of written instructions signed by both the Purchaser
and the Stockholder and otherwise in form and substance satisfactory to the
Escrow Agent, in accordance with such instructions.

         (d)  Upon receipt of written instructions signed by the Purchaser and
certifying that such Claim is made pursuant to Section 2.4 of the Acquisition
Agreement and accompanied by a certificate of the CPA Firm (as defined in the
Acquisition Agreement) setting forth the CPA Firm's calculation of the Net Asset
Amount (as defined in the Acquisition Agreement) and its calculation of the
amount due the Purchaser.

         (e)  Upon receipt of written instructions signed by the Purchaser and
accompanied by a final and non-appealable order, decree or judgment of a court
of competent jurisdiction in the United States of America in a proceeding to
which the Purchaser, on the one hand, and the Stockholder, on the other hand,
are parties directing such payment to the Purchaser.

         (f)  All expenses of the Escrow Agent shall be charged to the Escrow
Funds pursuant to Article 10 below.

         (g)  As expressly permitted by this Escrow Agreement and upon written
notice to the Purchaser and the Stockholder.

                                       3


                                    ARTICLE 4
                           DISPOSITION OF ESCROW FUNDS

         (a)  The Escrow Funds or any remaining portion thereof held hereunder
shall be released by the Escrow Agent to the Stockholder within five Business
Days after the Expiration Date (the "Distribution Date"); provided, however,
that, if a Notice of Claim shall have been delivered to the Escrow Agent prior
to the Expiration Date and the Claim set forth in such Notice of Claim is
pending and unresolved on the Distribution Date, only the amount of the Escrow
Funds in excess of that required to satisfy such Claim, as set forth in the
Notice of Claim, and any expenses of the Escrow Agent as permitted in Article 10
shall be released to the Stockholder. At such later time as all Claims have been
finally resolved and the amount of all such Claims has been paid to the
Purchaser, the balance of the Escrow Funds then held hereunder, if any, shall be
disbursed to the Stockholder.

         (b)  The Escrow Funds established by this Escrow Agreement shall
continue in effect until release of the entire Escrow Funds pursuant to the
provisions hereof.

                                    ARTICLE 5
                     PROVISIONS RELATING TO THE ESCROW AGENT

         (a)  The Escrow Agent agrees to hold the Escrow Funds under the terms
and conditions of this Escrow Agreement and to perform the acts and duties
imposed upon it hereby. If at any time in the performance of its duties
hereunder it is necessary for the Escrow Agent to receive, accept or act upon
any notice or writing purported to have been executed or issued by or on behalf
of the Purchaser or the Stockholder, it shall not be necessary for the Escrow
Agent to ascertain whether or not the person or persons who have executed,
signed or otherwise issued or authenticated said writing are authorized so to
execute, sign or otherwise issue or authenticate said writing, or that they are
the same persons named therein or otherwise to pass upon any requirements of
such instruments that may be essential for their validity.

         (b)  Notwithstanding anything herein to the contrary, the Escrow Agent
may act upon any written instructions given jointly by the Purchaser and the
Stockholder.

         (c)  The Escrow Agent shall not be personally liable for any act taken
or omitted by it hereunder if taken or omitted by it in good faith and in the
exercise of its own best judgment.

         (d)  The Escrow Agent may resign as such following the giving of 30
days' prior written notice to the Purchaser and the Stockholder. Similarly, the
Escrow Agent may be removed and replaced following the giving of 30 days' prior
written notice to the Escrow Agent by the Purchaser and the Stockholder. In
either event, the duties of the Escrow Agent shall terminate 30 days after the
date of such notice (or at such earlier date as may be mutually agreeable),
except for its obligations to hold and deliver the Escrow Funds to the successor
Escrow Agent; and the Escrow Agent shall then deliver the balance of the Escrow
Funds then in its possession to such a successor Escrow Agent as shall be
appointed by the Purchaser and the Stockholder as evidenced by a written notice
filed with the Escrow Agent. If the Purchaser and the Stockholder are unable to
agree upon a successor Escrow Agent by the effective date of such resignation or
removal, the then acting Escrow Agent may petition any court of competent

                                       4



jurisdiction for the appointment of a successor Escrow Agent or other
appropriate relief; and any such resulting appointment shall be binding upon all
of the parties hereto. Upon acknowledgment by any successor Escrow Agent of the
receipt of the then remaining balance of the Escrow Funds, the then acting
Escrow Agent shall be fully released and relieved of all duties,
responsibilities and obligations under this Escrow Agreement.


         (e)  The Escrow Agent shall be under no duty to institute or defend any
arbitration or legal proceeding with respect to the Escrow Funds or under this
Escrow Agreement and none of the costs or expenses of any such proceeding shall
be borne by the Escrow Agent. The costs and expenses of any such proceeding
shall be borne as decided by the arbitrators or court and shall be paid out of
the Escrow Funds or by the Purchaser, as the case may be.

                                    ARTICLE 6
                                SECURITY INTEREST

         The Stockholder hereby grants to the Purchaser a first priority
security interest in all of the Stockholder's and each of its Subsidiaries'
rights, title to and interest in the Escrow Funds held under this Escrow
Agreement for the purpose of securing, or partially securing, each and all of
its obligations to the Purchaser pursuant to Section 2.4 and Article VIII of the
Acquisition Agreement regardless of whether such obligations are required by the
Acquisition Agreement to be satisfied under this Escrow Agreement. The
Stockholder agrees to execute and deliver any such further instruments as the
Purchaser or the Escrow Agent may request from time to time evidencing such
security interest. The security interest granted pursuant to this Article 6
shall automatically terminate, with no further action necessary on the part of
the Purchaser, with respect to the portions of the Escrow Funds distributed
pursuant to this Escrow Agreement. The Purchaser agrees to execute and deliver
any such further instruments as the Stockholder or the Escrow Agent may request
from time to time evidencing termination such security interest in accordance
with the preceding sentence.

                                    ARTICLE 7

         Stockholder and Purchaser shall provide Escrow Agent with its taxpayer
identification number documented by an appropriate Form W-8 or Form W-9 upon
execution of this Escrow Agreement. Failure so to provide such forms may prevent
or delay disbursements from the Escrow Funds and may also result in the
assessment of a penalty and Escrow Agent's being required to withhold tax on any
interest or other income earned on the Escrow Funds. Any payments of income
shall be subject to applicable withholding regulations then in force in the
United States or any other jurisdiction, as applicable. The Stockholder shall be
deemed to be the owner of the Escrow Funds for federal, state and local income
tax purposes unless and until such funds are paid to the Purchaser.

         If any term or other provision of this Escrow Agreement is invalid,
illegal or incapable of being enforced by any rule of Law or public policy, all
other conditions and provisions of this Escrow Agreement shall nevertheless
remain in full force and effect so long as the economic or legal substance of
the transactions contemplated hereby is not affected in any manner materially
adverse to any party. Upon such determination that any term or other provision
is invalid, illegal or incapable of being enforced, the parties hereto shall
negotiate in good faith to modify this Escrow Agreement so as to effect the
original intent of the parties as closely as possible in an acceptable manner to
the end that transactions contemplated hereby are fulfilled to the extent
possible.

                                   ARTICLE 18
                                ENTIRE AGREEMENT

         This Escrow Agreement constitutes the entire agreement of the parties
hereto, and supercedes all prior agreements and undertakings, both written and
oral, among the parties or between any of them, with respect to the subject
matter hereof.

         Purchaser and Stockholder hereby jointly and severally agree to
indemnify and defend the Escrow Agent, its officers, directors, partners,
employees and agents (each herein called an "Indemnified Party") against, and
hold each Indemnified Party harmless from, any and all losses, liabilities and
expenses, including, but not limited to, fees and expenses of in house or
outside counsel, court costs, costs, damages and claims, costs of investigation,
litigation and arbitration, tax liability (other than for income taxes on fees
earned hereunder) and loss on investments suffered or incurred by any
Indemnified Party in connection with or arising from or out of (i) the
execution, delivery or performance of this Escrow Agreement or (ii) the
compliance or attempted compliance by any Indemnified Party with any instruction
or direction upon which the Escrow Agent is authorized to rely under this Escrow
Agreement, except to the extent that any such loss, liability or expense may
result from the willful misconduct or gross negligence of such Indemnified
Party. IT

IS THE EXPRESS INTENT OF EACH OF PURCHASER AND STOCKHOLDER TO INDEMNIFY EACH OF
THE INDEMNIFIED PARTIES FOR, AND HOLD THEM HARMLESS AGAINST, THEIR OWN NEGLIGENT
ACTS OR OMISSIONS (BUT NOT THEIR GROSS NEGLIGENCE OR WILLFUL MISCONDUCT).

                                   ARTICLE 20
                                 FUNDS TRANSFER

         In the event funds transfer instructions are given (other than in
writing at the time of execution of the Escrow Agreement), whether in writing,
by telefax, or otherwise, the Escrow Agent is authorized to seek confirmation of
such instructions by telephone call-back to the person or persons designated on
Exhibit B hereto, and the Escrow Agent may rely upon the confirmations of anyone
purporting to be the person or persons so designated. If the Escrow Agent is
unable to contact any of the authorized representatives identified in Exhibit B,
the Escrow Agent is hereby authorized to seek confirmation of such instructions
by telephone call-back to any one or more of the executive officers of the
Stockholder or the Purchaser ("Executive Officers"), which shall include the
titles of Vice President, as the Escrow Agent may select. Such "Executive
Officer" shall deliver to the Escrow Agent a fully executed Incumbency
Certificate, and the Escrow Agent may rely upon the confirmation of anyone
purporting to be any such officer. The persons and telephone numbers for
call-backs may be changed only in writing actually received and acknowledged by
the Escrow Agent. The parties to this Escrow Agreement acknowledge that such
security procedure is commercially reasonable.

         It is understood that the Escrow Agent and the beneficiary's bank in
any funds transfer may rely solely upon any account numbers or similar
identifying number provided by either of the other parties hereto to identify
(i) the beneficiary, (ii) the beneficiary's bank, or (iii) an intermediary bank.
The Escrow Agent may apply any of the Escrow Funds for any payment order it
executes using any such identifying number, even where its use may result in a
person other than the beneficiary being paid, or the transfer of funds to a bank
other than the beneficiary's bank or an intermediary bank so designated.

         The Escrow Agent's duties and responsibilities in connection with this
Escrow Agreement shall be purely ministerial and shall be limited to those
expressly set forth in this Escrow Agreement. The Escrow Agent is not a
principal, participant or beneficiary in any transaction underlying this Escrow
Agreement and shall have no duty to inquire beyond the terms and provisions
hereof. The Escrow Agent shall have no responsibility or obligation of any kind
in connection with this Escrow Agreement or the Escrow Funds and shall not be
required to deliver the Escrow Funds or any part thereof or take any action with
respect to any matters that might arise in connection therewith, other than to
receive, hold, invest, reinvest and deliver the Escrow Funds as herein provided.
Without limiting the generality of the foregoing, it is hereby expressly agreed
and stipulated by the parties hereto that the Escrow Agent shall not be required
to exercise any discretion hereunder and shall have no investment or management
responsibility and, accordingly, shall have no duty to, or liability for its
failure to, provide investment recommendations or investment advice to the
Purchaser, the Stockholder or either of them. The

any mistake of law or fact, or for anything it may do or refrain from doing in
connection herewith, except for, subject to Article 19 above, its own willful
misconduct or gross negligence. It is the intention of the parties hereto that
the Escrow Agent shall never be required to use, advance or risk its own funds
or otherwise incur financial liability in the performance of any of its duties
or the exercise of any of its rights and powers hereunder.

                                   ARTICLE 22

         EACH PARTY HEREBY WAIVES ALL RIGHT TO TRIAL BY JURY IN ANY ACTION,

ARISING OUT OF OR RELATING TO THIS ESCROW AGREEMENT OR THE ACTION OF THE ESCROW
AGENT, STOCKHOLDER OR PURCHASER IN THE NEGOTIATION, ADMINISTRATION, PERFORMANCE
AND ENFORCEMENT OF THIS ESCROW AGREEMENT. EACH PARTY CERTIFIES AND ACKNOWLEDGES
THAT (I) NO REPRESENTATIVE, AGENT OR ATTORNEY OF ANY OTHER PARTY HAS
REPRESENTED, EXPRESSLY OR OTHERWISE, THAT SUCH OTHER PARTY WOULD NOT, IN THE
EVENT OF LITIGATION, SEEK TO ENFORCE THE FOREGOING WAIVER; (II) SUCH PARTY
UNDERSTANDS AND HAS CONSIDERED THE IMPLICATIONS OF THE FOREGOING WAIVER; (III)
SUCH PARTY MAKES THE FOREGOING WAIVER VOLUNTARILY AND (IV) SUCH PARTY HAS BEEN
INDUCED TO ENTER INTO THIS AGREEMENT BY, AMONG OTHER THINGS, THE MUTUAL WAIVER

                                   ARTICLE 23
                              RULES OF CONSTRUCTION

         The parties hereto agree that they have been represented by counsel
during the negotiation and execution of this Escrow Agreement and, therefore,
waive the application of any law regulation, holding or rule of construction
providing that ambiguities in an agreement or other document will be construed
against the party drafting such agreement or document.
