<PAGE>

a prior Software release. Updates shall not include any releases or future
products, which Hyperion licenses separately.

2.    SPSS PORTING AND DISTRIBUTION RIGHTS

(a) PORT DEVELOPMENT. Hyperion shall make available to SPSS new releases of the
Software for the purpose of port development no later than the earliest date on
which Hyperion makes such new releases available to its beta test customers. New
releases of the Software are considered Technical Information and are subject to
the confidentiality provisions contained in Section 9(d). SPSS shall use its

are compatible with such new releases of the Software in a timely manner, so
that the new version of the ShowCase AS/400 Port is available for general
release no later than 180 days after the date of general release by Hyperion of
the new release of the Software. Upon Hyperion's written approval, which shall
not be unreasonably withheld, SPSS (i) may miss a particular release of the
Software or (ii) may not be required to port a feature of the Software.

(b) GRANT OF LICENSE TO DISTRIBUTE SOFTWARE ON AS/400 PLATFORM. Subject to the
terms and conditions of this Agreement, Hyperion grants to SPSS a non-exclusive,
non-transferable, non-sublicensable, license to use Technical Information, but
only as part of, and for the sole purpose of, permitting SPSS to port the
Software to the IBM AS/400 platform or any direct successor platform. Hyperion
also grants to SPSS a worldwide license to distribute, market and sublicense
through Resellers and directly to End Users executable versions of the ShowCase
AS/400 Port in the Territory. The End User shall execute a software license
agreement no less restrictive than, and at least as protective of, Hyperion's
rights and the then-current copy and use restrictions for such Software (the
current version is attached) contained in Hyperion's Software License and
Services Agreement attached to this Agreement as Exhibit B.

(c) CLOSING RESPONSIBILITIES. SPSS will be responsible for closing sales without
substantial field sales support from Hyperion.

(d) DEVELOPMENT/DEMONSTRATION COPIES. SPSS shall have the right to use copies of
the ShowCase AS/400 Port internally and to provide copies to its Resellers at no
charge and subject to no royalty payment, provided that such copies are used by
and on such Resellers' computer equipment solely for the following purposes: (i)
internal development and training of Resellers' employees solely for purposes of
distributing, marketing and supporting the ShowCase AS/400 Port; (ii) marketing
and demonstration of the ShowCase AS/400 Port to prospects; and (iii) providing
implementation services and training for the ShowCase AS/400 Port to End Users.
Under no conditions may such Resellers use copies of the ShowCase AS/400 Port to
run the internal operations of Reseller or for the benefit of any third party,
nor shall such copies be provided to any third party.

(e) TRADEMARK LICENSE. Subject to the terms and conditions of this Agreement,
Hyperion hereby grants to SPSS a non-exclusive, non-transferable license to use
its trademarks (the "Trademarks"), but only in the Territory and in connection
with its marketing and distribution of the Software and any derivative works
thereof expressly authorized under this Agreement. Every copy of the ShowCase
AS/400 Port shall clearly and prominently display "Essbase(R)" or the
appropriate Trademark and shall attribute authorship of the Technical
Information to Hyperion. SPSS shall use "Essbase(R)" or the appropriate
Trademark as part of the primary product name in a manner as least as prominent
as the trademark(s) of SPSS and such Trademarks shall not follow words such as
"of" or "for" or "powered by" (e.g., "ShowCase Widget for Essbase(R)" would not
be permissible). SPSS shall (1) upon Hyperion's request from time to time,
supply to Hyperion fully documented sample copies of the ShowCase AS/400 Port
(in both source code and object code form) and any advertising and marketing
materials, for Hyperion's review and approval, which shall not be unreasonably
withheld; (2) modify the ShowCase AS/400 Port and any such advertising and
marketing materials as may be reasonably requested by Hyperion to give full
attribution to Hyperion, ensuring that the Hyperion corporate and product names

Hyperion's Trademarks shall be consistent with the Hyperion Trademark Policy set
forth in the Hyperion partner portal at http://www.hyperion.com.

(f) MINIMUM ANNUAL QUOTA. SPSS shall endeavor to achieve the minimum annual
quotas during each annual period specified in Exhibit A. These quotas consist of
Sublicense Fees and End User Support Fees actually paid by SPSS to Hyperion.
SPSS failure to meet such minimum shall not be considered a breach of this
Agreement or a cause for termination.

(g) END USER SUPPORT FEES. SPSS shall provide First, Second and Third Level
Support to End Users and SPSS shall pay Hyperion the End User Support Fees set
forth in Exhibit A.

(h) HYPERION REPUTATION AND GOODWILL. SPSS shall not knowingly make false or

("Business Plan") outlining SPSS's go-to-market plan within thirty (30) days of
the Effective Date of this Agreement.

3.    HYPERION DISTRIBUTION RIGHTS

(a) GRANT OF LICENSE TO DISTRIBUTE SHOWCASE AS/400 PORT. Hyperion shall have the
right to distribute and sublicense the ShowCase AS/400 Port directly and through
its distributors, resellers and other partners. Hyperion may not without SPSS'
prior written approval distribute and sublicense the ShowCase AS/400 Port to any
of SPSS' Named Accounts set forth on Exhibit E as modified in writing by SPSS
from time to time upon written notice to Hyperion. The End User shall execute a
software license agreement containing terms no less restrictive than those
contained in the Software License Agreement attached to this Agreement as
Exhibit B. Hyperion shall submit written orders to SPSS and SPSS shall fulfill
such orders by promptly delivering and providing Hyperion with evidence of
delivery to the End User (in no event later than the last business day local
time) of the calendar quarter in which the order is submitted.

(b) TRADEMARK LICENSE. Subject to the terms and conditions of this Agreement,
SPSS hereby grants to Hyperion a non-exclusive, non-transferable license to use
the name "ShowCase" (the "Trademark"), but only in connection with its marketing
and distribution of the ShowCase AS/400 Port and in accordance to SPSS' written
trademark polices, a copy of which is attached hereto as Exhibit G. Every copy
of the ShowCase AS/400 Port shall clearly and prominently display the Trademark.

4. TERM AND TERMINATION

(a) TERM. This Agreement shall become effective on the Effective Date and shall
remain in effect for an initial term of [*] years ("Initial Term") and shall
automatically renew for subsequent one-year terms ("Renewal Term") unless sooner
terminated as provided below.

(b) TERMINATION FOR CAUSE. If either party breaches this Agreement, the
non-defaulting party may give written notice to the defaulting party of the

<PAGE>

(d) REMEDIES. Termination of this Agreement shall not limit or restrict any of
the remedies otherwise available to the parties hereunder or at law.

(e) EFFECTS OF TERMINATION. Upon termination of this Agreement for any reason,
all rights and licenses granted to SPSS under this Agreement shall terminate and
revert to Hyperion, except that sublicenses of the ShowCase AS/400 Port- granted
by SPSS to End Users in accordance with this Agreement as of the date of
termination will remain in effect in accordance with their terms and conditions.
Upon termination of this Agreement for any reason, SPSS shall (i) immediately
return to Hyperion all Hyperion Confidential Information including the Technical
Information, catalogues and literature in its possession, custody or control in
whichever form held (including all copies or embodiments thereof); (ii) cease
using any trademarks, service marks and other designations of Hyperion; (iii)
cease issuing new sublicenses of the ShowCase AS/400 Port; (iv) no longer
identify or hold itself out as a distributor of the ShowCase AS/400 Port or the
Software; and (v) without additional consideration, assign, convey and transfer
to Hyperion all right, title and interest in and to the ShowCase AS/400 Port.
Notwithstanding the foregoing and provided that the Agreement was not terminated
for violations of Hyperion's intellectual property rights, SPSS may, at its
discretion, retain a limited use license to use the ShowCase AS/400 Port and
related Documentation solely as required to fulfill its contractual duties to
support End Users for the remaining duration of the annual term of End User
Support agreements existing as of termination of this Agreement, provided that
SPSS has paid Hyperion the applicable End User Support Fees. Prior to the end of
the then-annual term of such End User Support agreements, SPSS may if it chooses
to, at its sole discretion, inform the End User to contact Hyperion to contract
directly with Hyperion for such software license and maintenance for the
ShowCase AS/400 Port. In addition to the foregoing, upon termination of this
Agreement, Hyperion may contact End Users using the End User information
provided by SPSS to Hyperion pursuant to Section 5(b) and Section 8 below and
arrange for such End Users to terminate their software license and maintenance
agreements with SPSS as of the end of the then-annual term and to contract
directly with Hyperion for such software license and maintenance for the
ShowCase AS/400 Port.

5.    FEES AND PAYMENT

(a) SUBLICENSE FEES PAYMENT TO HYPERION. For each sublicense of the ShowCase
AS/400 Port granted by SPSS, SPSS shall report and pay to Hyperion the
applicable Sublicense Fees stated in Exhibit A payable in accordance with
Section 5(b) below. Unless otherwise expressly stated in Exhibit A, the
applicable Sublicense Fees will be Hyperion's then-current local list price for
such Software in effect in the Territory, less the applicable discount specified
in Exhibit A for the type of sublicense granted. In the event discount levels
are changed, such changes will apply prospectively only and not retroactively.
Any prepaid Sublicense Fees paid by SPSS will be credited only against future
Sublicense Fees. Hyperion shall have the right to change its price lists at any
time, provided that any such change shall be effective under this Agreement upon
a minimum of sixty (60) days' written notice to SPSS.

(b) REPORTING OF SUBLICENSE FEES AND END USER SUPPORT FEES. Within thirty (30)
days following the end of each calendar month, SPSS shall provide to Hyperion a
written report detailing the information set forth in Exhibit C for all
sublicenses of the ShowCase AS/400 Port delivered and first year End User
Support sold to End Users by SPSS in the just completed month. Within thirty
(30) days following the end of each calendar quarter, SPSS shall provide to
Hyperion a written report detailing the information set forth in Exhibit C for
all anniversaries of all sublicenses sold (except for those sublicenses for
which the End User notifies SPSS that annual maintenance will not be renewed)
under this Agreement and the previous License Agreement between the parties
hereto dated April 1, 1998 as amended that occurred in the just completed
quarter. Such report shall include any credits for incorrectly reported
maintenance renewals on the prior quarter's report.

(c) HYPERION ROYALTY PAYMENT TO SPSS. Hyperion shall pay SPSS a royalty for each
copy of the ShowCase AS/400 Port distributed by Hyperion or its resellers. Such
royalty shall be equal to [*]

confidential information has been separately filed with the Securities and
Exchange Commission.

                                                                    Page 5 of 14
<PAGE>

percent ([*]%) of SPSS's then-current local list price. The parties agree to
negotiate in good faith regarding discounts for large transactions. SPSS agrees
to provide Hyperion with sixty (60) days' prior written notice of any change in
its list price. Hyperion agrees to pay and report any license sale under this
Section 5(c) within thirty (30) days of the quarter in which the license sale
occurs.

(d) HYPERION eLICENSING REQUIREMENT. During the term of this Agreement, SPSS
acknowledges and agrees to support and incorporate Hyperion's eLicensing
strategy that will require the ShowCase AS/400 Port to incorporate technology
that can enforce software licensing restrictions substantially similar to the
technology that Hyperion incorporates in the Software. For avoidance of doubt,
if Hyperion subsequently incorporates technology in the Software that can
enforce software licensing restrictions at the component level (i.e., beyond the
server level), SPSS shall promptly, provided that the parties may mutually agree
on an extended period because of any technical or practical issues, support and
incorporate such technology in the ShowCase AS/400 Port or other technology
developed or licensed by SPSS that can enforce software licensing restrictions
at the component level. Failure by SPSS to promptly, provided that the parties
may mutually agree on an extended period because of any technical or practical
issues, incorporate such additional technology into the ShowCase AS/400 Port
shall be deemed a material breach.

(e) MAINTENANCE OF BOOKS AND RECORDS. SPSS shall maintain accurate books and
records relating to the performance of its obligations under this Agreement for
at least three (3) years after expiration or termination of this Agreement.

(f) TERMS OF PAYMENT. All fees due under this Agreement are payable and due
within thirty (30) days of date of invoice. Late payments will bear interest at
the rate of one and one-half percent (1.5%) per month (or the maximum rate
allowed by law, whichever is lower). In addition, the payor will pay all charges
reasonably incurred in the purchase and/or shipment of Software, including
transportation charges, insurance premiums, taxes (except taxes based on
seller's net income), duties and other government assessments, except to the
extent expressly prohibited by law. Payor's obligation to pay the other party
shall not be affected by its ability to collect payment from its customers. All
fees charged by a party and payable by the other party do not include taxes. The
parties agree that all taxes shall be paid in accordance with Section 9 (j)
below.

(g) AUDIT. Hyperion may at any time, upon five (5) business days' written notice
and not more than once in each twelve month period, examine SPSS's books and
records related to the amounts due to Hyperion. Such examination may be done by
a certified public accounting firm, at Hyperion's expense, provided, however,
that if any such audit uncovers one or more underpayments in excess of five
percent (5%) of the total amount determined by the audit to be payable to
Hyperion for the audited period, SPSS shall immediately reimburse Hyperion for
the full costs of such audit and the amount of underpayment uncovered during the
course of the audit.

6.    MAINTENANCE SUPPORT

(a) SUPPORT FOR SPSS'S END USERS. SPSS shall provide First Level Support, Second
Level Support and Third Level Support to those customers who have purchased
licenses for the ShowCase AS/400 Port from SPSS or its Resellers. Hyperion will
provide secondary support in accordance with Exhibit H directly to SPSS (and not
to its Resellers or End Users) with respect to all such sales. Hyperion will
also provide Software Upgrades to SPSS. For such support, SPSS shall pay
Hyperion the End User Support Fees as set forth in Exhibit A.

(b) SUPPORT FOR SHOWCASE AS/400 PORT SALES BY HYPERION. Hyperion or its partner
can collect or cause to be collected and promptly pay to SPSS an annual
maintenance fee equal to 15 percent of the then-current SPSS local list price
for the ShowCase AS/400 Port when Hyperion originally licenses the ShowCase
AS/400 Port. The End User shall contract directly with SPSS for Support of the
ShowCase

Exchange Commission.

                                                                    Page 6 of 14
<PAGE>

AS/400 Port, and then SPSS will provide First, Second and Third Level
support directly to such End Users. After the first year of maintenance for a
customer, SPSS will handle all renewals and will extend its maintenance contract
to the customers at SPSS's then current rates.

7.    MARKETING ACTIVITIES

(a) PUBLICITY. Unless a party is required by law or due to an SEC requirement in
such party's reasonable judgment, neither party will issue any public
announcement nor publish any materials that reference or discuss the other party
or its products without the prior written consent of the other party. Each party
grants the other party the right to use the other party's name and logo for
marketing purposes.

(b) JOINT MARKETING. During the Term of this Agreement, SPSS and Hyperion may
mutually agree from time to time to engage in joint marketing activities which
promote their products including seminars, press announcements, trade shows,
user groups or other events.

8.    ESCROW OF SHOWCASE AS/400 PORT AND CURRENT END USER LIST. Promptly after
the release of each version of the ShowCase AS/400 Port, SPSS will put into
escrow the ShowCase AS/400 Port and all proprietary software, instructions and
notes necessary to recreate the development environment. Promptly after the
Effective Date of this Agreement, SPSS will put into escrow its current list of
End Users. Upon the termination of this Agreement, Hyperion shall be entitled to
have access to and use the source code form of the ShowCase AS/400 Port for the
purposes set forth in this Agreement and Hyperion shall be entitled to have
access to and use the list of End Users. The fees for this escrow arrangement
shall be paid by Hyperion and shall not exceed $650 per year.

9.    GENERAL TERMS AND CONDITIONS

(a)   OWNERSHIP OF SOFTWARE. Hyperion retains all right, title and interest
in the Software and in any ideas, know-how, programs, processes, designs,
inventions, works, trade secrets, and other information, which may be developed
by Hyperion in the course of providing any technical services, including any
enhancements or modifications made to the Software (collectively, "Hyperion
Materials"), and all patents, copyrights, trade secrets, and other proprietary
rights in or related to the Hyperion Materials, whether or not specifically
recognized or perfected under the laws of the country where the Hyperion
Materials are located. SPSS will not remove, alter or destroy any form of
copyright notice, proprietary markings or confidential legends placed upon or
contained within the Hyperion Materials. Further, SPSS will reproduce Hyperion's
copyright and other proprietary rights notices on any copies of the Hyperion
Materials it uses, including archival and backup copies.

modules to the ShowCase AS/400 Port, which have been or are developed by or for
SPSS without use of any source code of the ShowCase AS/400 Port.

(c)   RESTRICTIONS. SPSS shall not translate, disassemble, reverse engineer,
decompile or otherwise attempt to reconstruct or discover any source code or
underlying ideas or algorithms of, or embodied in, the Software. SPSS shall not
cause or permit unauthorized copying, reproduction or disclosure of any portion
of the Software, or any instructions, manuals, or other Documentation, or the
delivery or distribution of any part of either the Software or the
Documentation, to any third person or entity, for any purpose whatsoever,
including, but not limited to, transmission, uploading, downloading, leasing, or
operating the Software as a timeshare or service bureau without the prior
written consent of Hyperion.

(d)   CONFIDENTIAL INFORMATION.

      (i) "CONFIDENTIAL INFORMATION" means all information related to the
business of the disclosing party that may be obtained by the receiving party
from any source as a result of this Agreement, provided that if written, the
information is clearly identified as proprietary or confidential, and if oral,
shall

                                                                    Page 7 of 14
<PAGE>

be followed by a written summary of such oral communication within a reasonable
number of days of the date of disclosure. Confidential Information includes (but
is not limited to) source code, algorithms, concepts, pricing information,
business methods, business and technical plans, research and test results,
including the results of any performance or benchmark tests or evaluation of the
Software, or a potential acquirer of SPSS or the SPSS ShowCase AS/400 Port
business, or the fact that SPSS may be acquired or is looking to divest the SPSS
ShowCase AS/400 Port business, which shall be deemed Confidential Information
without being marked.

      (ii) WHAT IS NOT "CONFIDENTIAL INFORMATION". Confidential Information does
not include information that the receiving party can demonstrate through written
documentation (i) is or becomes publicly available through no act or omission of
the receiving party; (ii) the disclosing party discloses to a third party
without restriction on further disclosure; (iii) is rightfully disclosed to the
receiving party by a third party without restriction on disclosure; (iv) is
independently developed by the receiving party without access to the disclosing

third party any Confidential Information belonging to the other party without
the other party's prior written consent. Each party agrees that it will not use
the Confidential Information of the other party except as authorized in the
Agreement. Each party further agrees that it will maintain the confidentiality
of all Confidential Information of the other party and prevent the unauthorized
disclosure or use of any Confidential Information by its clients, customers,
employees, subcontractors or representatives. In no event shall any party use
less care to maintain the Confidential Information of the other party than it
uses to maintain the confidentiality of its own similar non-public information.
Each party further agrees to notify the other in writing of any misuse or
misappropriation of the other party's Confidential Information that may come to
its attention.

(e)   INDEMNIFICATION BY HYPERION.

      (i) PROVIDED BY HYPERION. Hyperion shall defend and hold SPSS harmless
from any claim by a third party that the Software infringes any patent, trade
secret or copyright of that third party in any jurisdiction in which SPSS is
licensed by Hyperion to use or distribute the Software, provided (i) Hyperion is
promptly notified in writing of the claim; (ii) Hyperion has sole control of the
defense and any negotiations for its settlement; and (iii) SPSS provides
Hyperion, at Hyperion's expense, with all reasonable assistance, information,
and authority necessary to perform the above.

      (ii) LIMITATIONS. This indemnity obligation shall not apply with respect
to a claim which arises (1) from the use of a superseded or modified release of
the Software, if the claim would have been avoided by the use of the current or
unmodified release (the parties agree that the porting of the Software by SPSS
under the terms of this Agreement is not considered a modification; (2) from the

informed of and provided modifications that would avoid the alleged
infringement.

      (iii) OPTIONS FOR REMEDY. Should the Software become, or in Hyperion's
opinion be likely to become, the subject of any such claim of infringement, then
the SPSS will permit Hyperion, at Hyperion's option and expense, either: (1) to
procure for SPSS the right to continue using the Software; (2) replace or modify
the Software so that its use becomes non-infringing without loosing substantial
functionality; or (3) refund the fees paid by SPSS to Hyperion for the allegedly
infringing Software, provided that the amount of fees subject to refund shall be
amortized on a straight line monthly basis over a five (5) year period.
