package are detailed in Part Two, and the dollar limitations on the overall

reduction in level of management to which he reports; also if the employee was a

Termination for Cause.

          Option means any outstanding option you hold under the Plan at the
time of the Change in Control or upon your subsequent Involuntary Termination.
Your Options will be divided into two (2) separate categories as follows:

               Acquisition-Accelerated Options: any outstanding Option (or
               -------------------------------
     installment thereof) which automatically accelerates, pursuant to the
     acceleration provisions of the agreement evidencing that Option, upon a
     Change in Control.

               Severance-Accelerated Options: any outstanding Option (or

Accelerated Option or any Severance-Accelerated Option, the portion of that
Option deemed to be a
<PAGE>

                                                                          Page 4

parachute payment under Code Section 280G and the Treasury Regulations issued
thereunder. The portion of such Option which is categorized as an Option
Parachute Payment will be calculated in accordance with the valuation provisions
established under Code Section 280G and the applicable Treasury Regulations and
will include an appropriate dollar adjustment to reflect the lapse of your
obligation to remain in the Company's employ as a condition to the vesting of
the accelerated installment. In no event, however, will the Option Parachute
Payment attributable to any Acquisition-Accelerated Option or Severance-
Accelerated Option (or accelerated installment) exceed the spread (the excess of
the Fair Market Value of the accelerated option shares over the option exercise
price payable for those shares) existing at the time of acceleration.

          Other Parachute Payment means any payment in the nature of
compensation (other than the benefits to which you become entitled under Part
Two of this letter agreement) which are made to you in connection with the
Change in Control and which accordingly qualify as parachute payments within the
meaning of Code Section 280G(b)(2) and the Treasury Regulations issued
thereunder.  Your Other Parachute Payment will include (without limitation) the
Present Value, measured as of the Change in Control, of the aggregate Option
Parachute Payment attributable to your Acquisition-Accelerated Options (if any).

          Parachute Payment means any payment or benefit provided you under Part
Two of this letter agreement (other than the Option Parachute Payment
attributable to your Severance-Accelerated Options) which is deemed to
constitute a parachute payment within the meaning of Code Section 280G(b)(2) and
the Treasury Regulations issued thereunder.

          Plan means (i) the Company's 1999 Stock Incentive Plan, as amended or
restated from time to time, (ii) the Company's 2000 Supplemental Stock Option
Plan and (iii) any successor stock incentive plan subsequently implemented by
the Company.

          Present Value means the value, determined as of the date of the Change
in Control, of any payment in the nature of compensation to which you become
entitled in connection with the Change in Control or your subsequent Involuntary
Termination, including (without limitation) the Option Parachute Payment
attributable to your Severance-Acceleration Options, the additional benefits to
which you become entitled under Part Two of this letter agreement and the Option
Parachute Payment attributable to your Acquisition-Accelerated Options.  The
Present Value of each such payment will be determined in accordance with the
provisions of Code Section 280G(d)(4), utilizing a discount rate equal to one
hundred twenty percent (120%) of the applicable Federal rate in effect at the
time of such determination, compounded semi-annually to the effective date of
the Change in Control.

          Target Bonus means the target bonus (as a percentage of base salary)
in effect for you under the Company's annual cash incentive bonus program
immediately prior to the

Change in Control or (if greater) the target bonus in effect for you at the time
of your Involuntary Termination.
<PAGE>

                                                                          Page 6

          Termination for Cause means the Company's termination of your
employment for any of the following reasons: (i) your commission of any act of
fraud, embezzlement or dishonesty, (ii) your unauthorized use or disclosure of
any confidential information or trade secrets of the Company, (iii) any
intentional misconduct by you which has a materially adverse effect upon the
Company's business or reputation, (iv) your continued failure to perform the
major duties, functions and responsibilities of your position after written
notice from the Company identifying the deficiencies in your performance and a
reasonable cure period of not less than thirty (30) days or (v) a material
breach of your fiduciary duties as an officer of the Company.

                     PART TWO -- CHANGE IN CONTROL BENEFITS

          Should your employment with the Company terminate by reason of an
Involuntary Termination within twelve (12) months after a Change in Control,
then you will become entitled to receive the severance benefits provided under
this Part Two, provided you execute and deliver to the Company, at the time of
such Involuntary Termination, a General Release in substantially the form of
attached Exhibit A.  However, your benefits under this Part Two will in all
events be subject to the benefit limitations of Part Three and the restrictive
covenants of Part Four of this letter agreement and will be in lieu of all other
severance benefits to which you might otherwise be entitled upon such
termination of your employment.

          1.  Accelerated Vesting.
              --------------------

          Each outstanding Option which you hold at the time of your Involuntary
Termination, to the extent not otherwise exercisable for all the shares of
Common Stock subject to that Option, will immediately vest and become
exercisable for all those option shares and may be exercised for any or all of
those shares as fully vested shares.  Each such accelerated Option granted prior
to the date of this letter agreement will remain exercisable until the earlier
                                                                       -------
of (i) the expiration of the option term or (ii) the end of the three (3)-month
period following the date of your Involuntary Termination, and each such
accelerated Option granted after the date of this letter agreement will remain
exercisable until the earlier of (x) the expiration of the option term or (y)
                      -------
the end of the twelve (12)-month period following the date of your Involuntary
Termination.  Any Options not exercised prior to the expiration of the
applicable post-service exercise period will lapse and cease to remain
exercisable.

          2.  Severance Payment.
              ------------------

          You will receive severance payments from the Company for a period of
three (3) years following your Involuntary Termination in an aggregate amount
equal to three (3) times the sum of your annual rate of Base Salary and Target
Bonus.  The salary continuation/target bonus payments shall be paid to you in
equal installments over the three (3) year period following your
<PAGE>

                                                                          Page 7

Involuntary Termination in accordance with the Company's normal payroll
practices and subject to all applicable withholding taxes.  The payments will
immediately terminate in the event you fail to abide by the restrictive
covenants set forth in Part Four of this letter agreement.

          3.  Health Care Coverage.
              ---------------------

          The Company will, at its expense, provide you and your eligible
dependents with continued health care coverage under the Company's
medical/dental plan until the earlier of (i) the expiration of the eighteen
                              -------
(18)-month period measured from the first day of the first month following the
effective date of your Involuntary Termination or (ii) the first date that you
are covered under another employer's health benefit program which provides
substantially the same level of benefits without exclusion for pre-existing
medical conditions.  Such Health Care Coverage will be in lieu of any other
continued health care coverage to which you or your dependents would otherwise
be entitled at your own cost under Code Section 4980B by reason of your
termination of employment.

                      PART THREE -- LIMITATION ON BENEFITS

          1.  Benefit Limit.
              --------------

          The aggregate Present Value (measured as of the Change in Control) of
the benefits to which you become entitled under Part Two at the time of your
Involuntary Termination, namely, the salary continuation/target bonus payments,
the Option Parachute Payment attributable to your Severance-Accelerated Options
and your Health-Care Coverage, will in no event exceed in amount the greater of
                                                                     -------
the following dollar amounts (the "Benefit Limit"):

               (a) 2.99 times your Average Compensation, less the Present Value
     (measured as of the Change in Control) of all Other Parachute Payments to
     which you are entitled, or

               (b) the amount which yields you the greatest after-tax amount of
     benefits under Part Two of this letter agreement after taking into account
     any excise tax imposed under Code Section 4999 on the payments and benefits
     which are provided you under Part Two or which constitute Other Parachute
     Payments.

          The Option Parachute Payment attributable to the accelerated vesting
of your Acquisition-Accelerated Options at the time of the Change in Control
shall also be subject to the Benefit Limit.
<PAGE>

                                                                          Page 8

          For purposes of applying the Benefit Limit to your benefits under Part
Two, the value of your non-competition covenant under Part Four of this letter
agreement shall be determined through independent appraisal by a nationally-
recognized independent accounting firm acceptable to both you and the Company
and obtained solely at the Company's cost,  and a portion of your Part Two
benefits shall, to the extent of such appraised value, be specifically allocated
as reasonable compensation for your non-competition covenant.

          2.  Resolution Procedure.
              ---------------------

          In the event there is any disagreement between you and the Company as
to whether one or more payments to which you become entitled in connection with
either the Change in Control or your subsequent Involuntary Termination
constitute Parachute Payments, Option Parachute Payments or Other Parachute
Payments or as to the determination of the Present Value of any of those
payments, such dispute will be resolved as follows:

              (i)    In the event temporary, proposed or final Treasury
          Regulations in effect at the time under Code Section 280G (or
          applicable judicial decisions) specifically address the status of any
          such payment or the method of valuation therefor, the characterization
          afforded to such payment by the Regulations (or such decisions) will,
          together with the applicable valuation methodology, be controlling.

              (ii)   In the event Treasury Regulations (or applicable judicial
          decisions) do not address the status of any payment in dispute, the
          matter will be submitted for resolution to independent tax counsel
          mutually acceptable to you and the Company ("Independent Counsel").
          The resolution reached by Independent Counsel will be final and
          controlling; provided, however, that if in the judgment of Independent
                       --------
          Counsel the status of the payment in dispute can be resolved through
          the obtainment of a private letter ruling from the Internal Revenue
          Service, a formal and proper request for such ruling will be prepared
          and submitted by Independent Counsel, and the determination made by
          the Internal Revenue Service in the issued ruling will be controlling.
          All expenses incurred in connection with the retention of Independent
          Counsel and (if applicable) the preparation and submission of the
          ruling request will be shared equally by you and the Company.

              (iii)  In the event Treasury Regulations (or applicable judicial
          decisions) do not address the appropriate valuation methodology for
          any payment in dispute, the Present Value thereof will, at the
          Independent
<PAGE>

                                                                          Page 9

          Counsel's election, be determined through an independent third-party
          appraisal, and the expenses incurred in obtaining such appraisal will
          be shared equally by you and the Company.

          3.  Status of Benefits.
              -------------------

          A.  No benefits shall be provided you under Part Two of this letter
agreement (including the accelerated vesting of your outstanding Options, the
salary continuation/target bonus payments and the Company-paid Health Care
Coverage) until the Present Value of the Option Parachute Payment attributable
to both your Severance-Accelerated Options and your Acquisition-Accelerated
Options has been determined and the status of any payments in dispute under
Paragraph 5 above has been resolved in accordance therewith.  The post-service
exercise period in effect for your Options shall be stayed and shall not run
until the resolution process hereunder is completed.

          B.  Once the requisite determinations under Paragraph 5 have been
made, then to the extent the aggregate Present Value, measured as of the Change
in Control, of (i) the Option Parachute Payment attributable to your Severance-
Accelerated Options (or installments thereof) plus (ii) the Parachute Payment
attributable to your other benefit entitlements under Part Two of this letter
agreement would, when added to the Present Value of all your Other Parachute
Payments (including the Option Parachute Payment attributable to your
Acquisition-Accelerated Options), exceed the Benefit Limit, first your salary
continuation/target bonus payments will be reduced and then the period of your
Company-paid Health Care Coverage will be shortened,  to the extent necessary to
assure that such Benefit Limit is not exceeded.   To the extent such Benefit
Limit is still exceeded following such reductions, then the number of shares for
which your Options are to vest on an accelerated basis pursuant to Part Two
(based on the amount of the Option Parachute Payment attributable to each
Option) shall be reduced to the extent necessary to eliminate such excess.

                 PART FOUR -- SPECIAL RESTRICTIVE COVENANTS

          1.  Cessation of Benefits.
              ----------------------

          Your entitlement to your salary continuation/target bonus payments and
Company-paid Health Care Coverage under this letter agreement will immediately
cease, should  you:

              (a) render, anywhere in the United States, any services or
     provide any advice or assistance to any Competing Business, whether as an
     employee, consultant, partner, principal, agent, representative, equity
     holder or in any other capacity, without the express prior written consent
     of the Company.
<PAGE>

                                                                         Page 10

     However, nothing in Part Four, subpart 1(a) will limit your making any
     passive investment representing an interest of less than two percent (2%)
     of an outstanding class of publicly-traded securities of any corporation or
     other enterprise;

              (b) solicit customers, clients, suppliers, agents or other
     persons or entities under contract or otherwise associated or doing
     business with the Company and/or its controlled affiliates to reduce or
     alter any such association or business with the Company and/or its
     controlled affiliates on behalf of any Competing Business; and/or

              (c) solicit any employee or contractor of the Company and/or its
     controlled affiliates to (i) alter or reduce such relationship with the
     Company, and/or (ii) accept employment, or enter into any consulting
     arrangement, with any person other than Company and/or its controlled
     affiliates.

          A Competing Business shall mean the ten companies designated by the
Company on the list attached hereto as Exhibit B.  The Company may revise
Exhibit B at any time by adding names to, or subtracting names from, such list;
provided, however, that the Company must comply with the following requirements
--------
in making any changes to Exhibit B:  1) absent your express written consent, any
such change to Exhibit B must be made at least ninety days before termination of
your employment for any reason; 2) any change must be made in writing and either
personally delivered to you or sent to your last known address by certified mail
return receipt requested; and 3) the Company can never include more than ten
company names on Exhibit B.  (Thus, if Exhibit B contains ten company names and
the Company adds one or more company names to Exhibit B, then it must delete a
like number.  If the Company publishes a version of Exhibit B with more than ten
names, then such list will not be binding and the last version of Exhibit B with
ten Company names will be binding.);

              (a) provided, however, that such restriction will not apply to
                  --------
     any passive investment representing an interest of less than two percent
     (2%) of an outstanding class of publicly-traded securities of any
     corporation or other enterprise; The Board may amend the list of
     competitive entities once per year to update the list to include
     enterprises which are engaged in substantial business activities directly
     competitive with or similar to those in which the Company is engaged at the
     time of your Involuntary Termination or to which the Company has, prior to
     your Involuntary Termination, devoted substantial resources in connection
     with the proposed expansion of its then current business operations.

              (b) encourage or solicit any of the Company's employees to leave
     the Company's employ for any reason or interfere in any other manner with
<PAGE>

                                                                         Page 11

     employment relationships at the time existing between the Company and its
     employees; or

              (c) induce any of the Company's clients, customers, suppliers,
     vendors, distributors, licensors or licensees to terminate their existing
     business relationships with the Company or interfere in any other manner
     with any existing business relationship between the Company and any client,
     customer, supplier, vendor, distributor, licensor, licensee  or other third
     party.

                           PART FIVE -- MISCELLANEOUS

          1.  Amendment and Termination.
              --------------------------

          This letter agreement may only be amended by written instrument signed

remain in effect through December 31, 2001 or any earlier termination of your
employment with the Company.  Provided you continue in the Company's employ,
this letter agreement shall automatically be renewed for successive one (1)-year
terms, beginning January 1, 2002, unless the Company provides you with written

occurs, this letter agreement may not be terminated at any time prior to the
expiration of the twelve (12)-month period following the effective date of that
Change of Control, and no subsequent termination of this letter agreement shall
adversely affect your right to receive any benefits to which you may have
previously become entitled hereunder in connection with your Involuntary
Termination following that Change in Control.

                                                                         Page 12

          2.  Termination for Cause.
              ----------------------

          Should your employment cease by reason of a Termination for Cause or
should you voluntarily resign under circumstances which would otherwise
constitute grounds for a Termination for Cause, then the Company will only be
required to pay you (i) any unpaid compensation earned for services previously
rendered through the date of such termination and (ii) any accrued but unpaid
vacation benefits or sick days, and no benefits will be payable to you under
Part Two of this letter agreement.

          3.  Death.
              ------

          Should you die before receipt of one or more salary
continuation/target bonus payments to which you become entitled under this
letter agreement, then those payments will be made to the executors or
administrators of your estate.  Should you die before you exercise all your
outstanding Options as accelerated hereunder, then such Options may be
exercised, within twelve (12) months after your death, by the executors or
administrators of your estate or by persons to whom the Options are transferred
pursuant to your will or in accordance with the laws of inheritance.  In no
event, however, may any such Option be exercised after the specified expiration
date of the option term.

          4.  Indemnification.
              ----------------

          The indemnification provisions for Officers and Directors under the
Company By-Laws will (to the maximum extent permitted by law) be extended to
you, during the period following your Involuntary Termination, with respect to
any and all matters, events or transactions occurring or effected during your
period of employment with the Company.

          5.  Miscellaneous.
              --------------

          This letter agreement will be binding upon the Company, its successors
and assigns (including, without limitation, the surviving entity in any Change
in Control) and is to be construed and interpreted under the laws of the State
of California.  This letter agreement supersedes all prior agreements between
you and the Company relating to the subject of severance benefits payable upon a
change in control or ownership of the Company, and you will not be entitled to
any other severance benefits upon such a termination other than those that are
provided in this letter agreement.  If any provision of this letter agreement as
applied to you or the Company or to any circumstance should be adjudged by a
court of competent jurisdiction to be void or unenforceable for any reason, the
invalidity of that provision will in no way affect (to the maximum extent
permissible by law) the application of such provision under circumstances
different from those adjudicated by the court, the application of any other
provision of this letter
<PAGE>

                                                                         Page 13

agreement, or the enforceability or invalidity of this letter agreement as a
whole.  Should any provision of this letter agreement become or be deemed
invalid, illegal or unenforceable in any jurisdiction by reason of the scope,
extent or duration of its coverage, then such provision will be deemed amended
to the extent necessary to conform to applicable law so as to be valid and
enforceable or, if such provision cannot be so amended without materially
altering the intention of the parties, then such provision will be stricken and
the remainder of this letter agreement will continue in full force and effect.

          6.  General Creditor Status.
              ------------------------

          All cash payments to which you become entitled hereunder will be paid,
when due, from the general assets of the Company, and no trust fund, escrow
arrangement or other segregated account will be established as a funding vehicle
for such payment.  Accordingly, your right (or the right of the personal
representatives or beneficiaries of your estate) to receive such cash payments
hereunder will at all times be that of a general creditor of the Company and
will have no priority over the claims of other general creditors.

          7.  At Will Employment.
              -------------------

          Nothing in this letter agreement is intended to provide you with any
right to continue in the employ of the Company (or any subsidiary) for any
period of specific duration or interfere with or otherwise restrict in any way
your rights or the rights of the Company (or any subsidiary), which rights are
hereby expressly reserved by each, to terminate your employment at any time and
for any reason.

          Please indicate your agreement with the foregoing terms and conditions
of your change in control severance package by signing the Acceptance section of
the enclosed copy of this letter and returning it to the Company.

                                         Very truly yours,

                                         PORTAL SOFTWARE, INC.

                                   ACCEPTANCE

          I hereby agree to all the terms and provisions of the foregoing letter
agreement governing the special benefits to which I may become entitled in the
event my employment should terminate under certain prescribed circumstances
following a substantial change in control or ownership of the Company.

                                GENERAL RELEASE
                                ---------------
<PAGE>

                          RELEASE AND WAIVER OF CLAIMS
                          ----------------------------

          In consideration of the severance payments and other benefits to which
I have become entitled, pursuant to that certain letter agreement between Portal
Software, Inc., a Delaware corporation (the "Company"), and myself dated
___________, 2000 (the "Severance Agreement"), in connection with the
termination of my employment on this date, I, _______________________,   hereby
furnish the Company with the following release and waiver ("Release and
Waiver").

          I hereby release and forever discharge the Company, its officers,
directors, agents, employees, stockholders, successors, assigns and affiliates
from any and all claims, liabilities, demands, causes of action, costs,
expenses, attorney fees, damages, indemnities and obligations of every kind and
nature, in law, equity or otherwise, known and unknown, suspected and
unsuspected, disclosed and undisclosed, arising from or relating to my
employment with the Company and the termination of that employment, including
(without limitation) claims of wrongful discharge, emotional distress,
defamation, fraud, breach of contract, breach of the covenant of good faith and
fair dealing, discrimination claims based on sex, age, race, national origin,
disability or any other basis under Title VII of the Civil Rights Act of 1964,
as amended, the California Fair Employment and Housing Act, the Federal Age
Discrimination in Employment Act of 1967, as amended ("ADEA"),  the Americans
with Disability Act,  contract claims, tort claims, and wage or benefit claims,
including but not limited to, claims for salary, bonuses, commissions, stock
grants, stock options, vacation pay, fringe benefits, severance pay or any other
form of compensation (other than the payments and benefits to which I am
entitled under the Severance Agreement).

          In releasing claims unknown to me at present, I am waiving all rights
and benefits under Section 1542 of the California Civil Code, and any law or
legal principle of similar effect in any jurisdiction:  "A general release does
not extend to claims which the creditor does not know or suspect to exist in his
favor at the time of executing the release, which if known by him must have
materially affected his settlement with the debtor."

          This Release and Waiver does not pertain to any claims which may
subsequently arise in connection with the Company's default in any of its
payment obligations under the Severance Agreement.

          I acknowledge that, among other rights subject to his Release and
Waiver, I am hereby waiving and releasing any rights I may have under ADEA, that
this release and waiver is knowing and voluntary, and that the consideration
given for this release and waiver is in addition to anything of value to which I
was already entitled as an executive of the Company.  I further acknowledge that
I have been advised, as required by the Older Workers Benefit Protection Act,
that:  (a) the release and waiver granted herein does not relate to claims which
may arise after this release and waiver is executed; (b) I have the right to
consult with an attorney prior to executing this release and waiver (although I
may choose voluntarily not to do so); and if I am

over 40 years old upon execution of this (c) I have twenty-one (21) days from
the date of termination of my employment with the Company in which to consider
this release and waiver (although I may choose voluntarily to execute this
release and waiver earlier); (d) I have seven (7) days following the execution
of this release and waiver to revoke my consent to this release and waiver; and
(e) this release and waiver shall not be effective until the seven (7)-day
revocation period has expired.

confidentiality provisions of this Agreement. Licensee will not transport,
export, or re-export of the Licensed Software, in whole or in part in violation
of the import or export control laws or regulations of the United States or any
other applicable country.

5  LICENSE AND SUPPORT SERVICES FEES
Licensee will pay Portal the license, services and Support Services fees as set
forth on Schedule A and in each applicable Order.

6  PAYMENTS AND TAXES
6.1  Invoices for amounts due under this Agreement shall be due and payable on
the date set forth in Schedule A or relevant Order(s). If no date is stated,
payment shall be due thirty (30) calendar days from Licensee's receipt of
invoice.

6.2  All payments due under this Agreement shall be made in U.S. dollars. In
addition to any remedies Portal may have hereunder or at law, any payments more
than thirty (30) days overdue will bear a late payment fee of 1.5% per month
commencing from the payment due date. If the foregoing would not be enforceable
under applicable law, then the applicable late payment fee shall be an amount
equal to the maximum rate allowed by law, accruing from the payment due date.

6.3  Portal may suspend or terminate Support Services for non-payment continuing
for more than fifteen (15) calendar days after Licensee's receipt of a written
notice from Portal informing of the failure to pay when due. Portal shall have
no liability for damages sustained by Licensee resulting from such termination
or suspension of Support Services pursuant to this Section 6.3.

6.4  The amounts set forth in this Agreement and all Orders hereunder are
exclusive of all taxes (including without limitation, value added taxes and
withholding taxes), tariffs, duties and the like. If Portal is required to pay
any sales, use, value-added, withholding or other tax, tariff, duty, etc.,
(other than taxes on Portal's net income) on the licenses or services provided
pursuant to this Agreement or pertaining to Licensee's use of the Licensed
Software, then such taxes shall be billed to and paid by Licensee.

7  SUPPORT SERVICES
Provided Licensee has paid the applicable Support Services fees, Portal,
directly or through or its authorized agent, shall provide Licensee with
technical support services in accordance with the Support Services plan
purchased by Licensee as set forth on Schedule A. Portal reserves the right to
modify its Support Services plans any time. Portal will notify Licensee in
writing of any material modifications to Portal's Support Services plans.
Licensee shall designate one primary technical support liaison and one backup
technical support liaison who will be permitted to contact Portal during
applicable technical support services hours. Portal will support each Major
Release of the Licensed Software for at least eighteen (18) months from its
initial  commercial release ("Support Term"). Portal shall have no obligation to
support (i) Licensed Software which has been damaged due to Licensee's
negligence, abuse, or misapplication, (ii) Licensed Software which has been
modified or altered in a manner not expressly authorized by Portal, (iii)
problems caused by use of the Licensed Software other than in accordance with
the Documentation, or (iv) Licensed Software installed in an operating
environment or hardware platform other than that for which it has been designed
as set forth in the applicable Documentation. Licensee will reasonably cooperate
with Portal in the resolution of support issues and, upon Portal's request and
during normal business hours, shall provide Portal with remote access to the
equipment on which the Licensed Software is installed and/or operating. Portal
will abide by Licensee's security policies and procedures and will only use such
remote access to provide Support Services for the Licensed Software. Licensee
understands that failure to provide Portal with such remote access may result in
delayed resolution of Support Services issues. If Licensee fails to provide
Portal with the above described remote access, Portal shall have no liability
for damages arising from delays which could reasonably have been avoided had
Licensee provided Portal with above-described dial-in access. Unless cancelled
by Licensee at least sixty (60) days prior to the termination of the then
current annual Support Services term, Support Services for supported products
will automatically renew at the same support level (if available) unless
terminated by Licensee or Portal as permitted under this Agreement.

8  CONSULTING SERVICES
Subject to payment of the applicable fees, Portal will provide Licensee with the
Support Services, training services and technical account management ("TAM")
services set forth on Schedule A. Additionally, Portal may from time to time
provide Licensed Software implementation or other professional consulting
services agreed to by both parties ("Consulting Services"). Prior to the
scheduling of such Consulting Services, Licensee and Portal will enter into a
Professional Services Agreement separate from this Agreement. Unless otherwise
agreed in writing, all Consulting Services will be billed on a time and
materials basis. Consulting Services are bid separately from the Licensed
Software licenses, and Licensee may acquire either Licensed Software licenses or
Consulting Services without acquiring the other.

9  RESTRICTED RELEASES
If Licensee is selected for participation and elects to participate in a
Restricted Release program, Licensee agrees (i) Portal shall have no obligation
to correct errors in or deliver updates to the Restricted Release, (ii) Portal
shall have no obligation to support the Restricted Release, (iii) Licensee will
provide Portal with appropriate test data for the Restricted Release if
necessary to resolve problems in the Restricted Release encountered by Licensee
and will promptly report to Portal any error discovered in the Restricted
Release, (iv) the Restricted Release is experimental, may contain problems and
errors and is being provided to Licensee on an "AS-IS" basis with no warranty of
any kind, express or implied, (v) neither party will be responsible to the other
for any losses, claims or damages of whatever nature, arising out of or in
connection with the performance or nonperformance of the Restricted Release,
(vi) Licensee will not use the Restricted Release in production applications
without the prior written approval of Portal, and (vii) Licensee will stop using
and return or destroy any Restricted Release promptly upon Portal's request.

10  TERMINATION
Portal may terminate a license to a Licensed Software product if Licensee fails
to pay the license fee therefor within fifteen (15) calendar days after written
notice from Portal that payment is past due. Either party may terminate this
Agreement if the other party breaches a material term of this Agreement and
fails to cure such breach within sixty (60) calendar days after receipt of
written notice describing the breach in reasonable detail. Upon termination of
this Agreement, all licenses granted hereunder shall immediately terminate,
Licensee shall immediately cease using the Licensed Software and Documentation
and Licensee shall certify in writing to Portal that all copies (in any form or
media) have been destroyed or returned to Portal. Termination shall not relieve
Licensee from paying all amounts accrued under this Agreement prior to
termination and shall not limit either party from pursuing any other available
remedies. Sections 4, 5,

                                                                    Page 2 of 10
<PAGE>

6, 10, 11, 13, 14, 15.1, 17, 18 and 19 shall survive termination or expiration
of this Agreement.

11  INFRINGEMENT INDEMNITY
Portal at its own expense shall (i) defend or at its option settle, any claim or
suit against Licensee on the basis of infringement of any trademark, copyright,
trade secret or United States patent ("Intellectual Property Rights") by the
Licensed Software or permitted use thereof, and (ii) pay any final judgment
entered against Licensee on such issue or any settlement thereof, provided (a)
Portal has sole control of the defense and/or settlement, (b) Licensee notifies
Portal promptly in writing of each such claim or suit and gives Portal all
information known to Licensee relating thereto, and (c) Licensee cooperates with
Portal in the settlement and/or defense. (Licensee shall be reimbursed for all
reasonable out-of-pocket expenses incurred in providing any cooperation
requested by Portal.) If all or any portion of the Licensed Software is, or in
the opinion of Portal may become, the subject for any claim or suit for
infringement of any Intellectual Property Rights, Portal may, and in the event
of any adjudication that the Licensed Software or any part thereof does infringe
or if the permitted use of the Licensed Software or any part thereof is
enjoined, Portal shall, at its expense do one of the following things: (1)
procure for Licensee the right to use the Licensed Software or the affected part
thereof; (2) replace the Licensed Software or affected part with other suitable
programs; (3) modify the Licensed Software or affected part to make it non-

remedies under this Agreement must be in writing to be effective.  Failure,

such party's rights under this Agreement and will not in any way affect the
validity of the whole or any part of this Agreement or prejudice such party's
right to take subsequent action.

19.3  If any term, condition or provision in this Agreement is found to be
invalid, unlawful or unenforceable to any extent, the parties shall endeavor in
good faith to agree to such amendments that will preserve, as far as possible,
the intentions expressed in this Agreement. If the parties fail to agree on such
an amendment, such invalid term, condition or provision will be severed from the
remaining terms, conditions and provisions, which will continue to be valid and
enforceable to the fullest extent permitted by law.

19.4  This Agreement (including the Schedules and any addenda hereto signed by
both parties) contains the entire agreement of the parties with respect to the
subject matter of this Agreement and supersedes all previous communications,
representations, understandings and agreements, either oral or written, between
the parties with respect to said subject matter. No employee, agent,
representative or affiliate of Portal has authority to bind Portal to any oral
representations or warranty concerning the Licensed Software. Any written
representation or warranty not expressly contained in this Agreement is
unenforceable.

19.5  No terms, provisions or conditions of any purchase order, acknowledgement
or other business form that Licensee may use in connection with the acquisition

or obligations of the parties under, or otherwise modify, this Agreement,
regardless of any failure of Portal to object to such terms, provisions, or
conditions.

19.6  The parties agree to reasonably cooperate in joint marketing  and public
relations activities including without limitation the issuance of a joint press

without Licensee's consent)  with a senior-level spokesperson within Licensee's
organization involved with the implementation of the Portal solution. Portal may
write and publish a high-level success story profile based on the interview and
discussing the reasons supporting Licensee's choice of the Portal solution and
the benefits realized by Licensee. Licensee shall have final approval over the
final content of such literature prior to initial distribution by Portal. Except
as provided in this Agreement, neither party will engage in joint public
relations activities without the prior written consent of the other party, which
consent shall not be unreasonably withheld, conditioned or delayed.

request, participate in at least four (4) telephone reference inquiries per year
and at least one (1) onsite visit per year provided that Portal shall give
Licensee reasonable advance notice of not less than (i) 48 hours in the case of
a telephone reference visit and (ii) 7 days in the case of an onsite visit.
Further, Portal shall be permitted to identify Licensee as a customer so long as
such use does not imply endorsement.

will be deemed to be an original and such counterparts together will constitute
one and the same Agreement.

19.9  Portal is an independent contractor; nothing in this Agreement shall be
construed to create a partnership, joint venture or agency relationship between
the parties.

19.11  In the event that this Agreement or the licenses granted hereunder should
ever become subject to US bankruptcy proceedings, all rights and licenses
granted under or pursuant to this Agreement by Portal to Licensee are, and shall
otherwise be deemed to be, licenses of rights to "intellectual property" as
defined in Section 365(n) of the Bankruptcy Code (11 U.S.C. Section 101 et.
seq.).  The parties agree that Licensee, as a licensee of such rights, shall
retain and may fully exercise all of the rights and election under Section
365(n) of the Bankruptcy Code.  The parties further agree that, in the event
that any proceeding shall be instituted by or against Portal seeking to
adjudicate it  bankrupt, or insolvent, or seeking liquidation, winding up,
reorganization, insolvency or reorganization, or relief of debtors, or seeking
an entry of an order of relief, or the appointment of a receiver, trustee or
other similar official for it or any substantial part of its property or it
shall take any action to authorize any of the foregoing actions,  Licensee shall
have the right to retain and enforce its rights under this Agreement as provided
under Section 365(n) of the Bankruptcy Code, including but not limited to, the
right to continue to use the Licensed Software in accordance with the terms and
conditions of this Agreement.

19.12  This Agreement will be interpreted and construed pursuant to the laws of
the State of California and the United States without regard to conflict of laws
provisions thereof, and without regard to the United Nations Convention on the
International Sale of Goods. Any legal action or proceeding relating to this
Agreement shall be instituted in a state or federal court in Santa Clara County,

agree that venue is proper in, these courts in any such action or proceeding.

19.13  The prevailing party in any action to enforce this Agreement will be
entitled to recover its reasonable attorney's fees and costs in connection with
such action.

19.14   The provisions of this Agreement allocate the risks between Portal and
Licensee. Licensee's pricing reflects this allocation of risk and the limitation
of liability specified in this Agreement.

19.15  The parties have requested that this Agreement and all documents
contemplated hereby be drawn up in English.
