     WHEREAS, SPSS also is engaged in the business of developing and
distributing software; and

     WHEREAS, DataStat desires to sell to SPSS, and SPSS desires to purchase
from DataStat, certain of DataStat's assets relating to Vstat exclusively;

     NOW, THEREFORE, in consideration of the premises, the mutual covenants and
agreements contained herein, and other good and valuable consideration, the
receipt and sufficiency of which are hereby acknowledged, and in reliance upon
the representations and warranties contained herein, the parties hereto agree as

                           TERMS OF PURCHASE AND SALE

     1.1 Purchase and Sale. Except as set forth below or in Section 1.4 and
subject to the terms and conditions of this Agreement, on the Closing Date (as
defined herein), DataStat hereby agrees to sell, convey, assign, transfer and

               VStat computer program code and related technical manuals, and
               all other Technical Documentation shall be delivered by DataStat
               to SPSS within 30 days of the Closing Date;

          (b)  with respect to VStat, all of DataStat's rights and benefits (but
               excluding, unless otherwise specifically provided herein, all

               with any person or entity respecting the ownership, license,
               acquisition, design, development, distribution, marketing, use or
               maintenance of VStat computer program code and related technical
               or user documentation (the "Contracts").

          (c)  the name "VerbaStat" and any trade names, trademarks and service
               marks related thereto (including registrations, licenses and
               applications pertaining thereto), whether registered or at common
               law, together with all goodwill associated therewith with the
               exception of the same relating to the name "DataStat";

          (d)  with respect to VStat, all of DataStat's parts lists, vendor
               lists, customer lists, catalogues, promotion lists and marketing
               data and other compilations of names and requirements, and trade
               secrets and other material information used by DataStat with
               respect to VStat; provided, however, that prior to the Closing
               Date, DataStat delivered to SPSS its lists of current and

               secrets or proprietary information related to VStat with the
               exception of all rights, including rights in patents and patent
               applications, in a data extraction method used in VStat more
               precisely described in the Belgian patent application of November
               25, 1999, n(degree)09900767 and generally referred to as the
               "Keyword Search" methodology; provided, however, that DataStat
               hereby grants to SPSS, for no additional consideration, a
               perpetual, non- exclusive license to use the source code of
               "Keyword Search" and such methodology in any way SPSS desires,
               including, without limitation, the modification or enhancement
               thereof or the inclusion or incorporation of such source code or
               methodology in any current or future products or applications of
               SPSS or its subsidiaries or affiliates. Notwithstanding anything
               herein to the contrary, SPSS has the right to transfer or assign
               such license to any third party that acquires the VStat business
               from SPSS or acquires all or substantially all of the stock of
               SPSS without the consent of DataStat, it being understood and
               agreed that such license shall be binding upon DataStat and its
               successors and assigns, and shall inure to the benefit of SPSS
               and its successors and assigns. Notwithstanding the foregoing,
               SPSS shall not sell the "Keyword Search" methodology as a
               stand-alone product without DataStat's consent.

     1.2 Time and Place of Closing. Subject to the terms and conditions of this
Agreement, the consummation of the transactions contemplated hereby (the
"Closing") shall take place at the offices of Ross & Hardies, 150 N. Michigan
Avenue, Chicago, Illinois on December 23, 1999 (the "Closing Date") or at such
other place or time as the parties may agree and, for all purposes, shall be
deemed to be effective as of the close of business on December 23, 1999.
Signatures delivered by facsimile transmission shall be deemed original.

     1.3 Purchase Price. Upon satisfaction of all of the terms and conditions
set forth in this Agreement, SPSS shall deliver the Purchase Price consisting of
ONE MILLION AND NO/100 U.S. DOLLARS (U.S.$1,000,000.00), to be paid in twelve
quarterly installments the first eleven of which shall be EIGHTY THREE THOUSAND
THREE HUNDRED THIRTY-THREE AND 33/100 U.S. DOLLARS (U.S.$83,333.33) and the
twelfth of which shall be EIGHTY THREE THOUSAND THREE HUNDRED THIRTY-THREE AND
40/100 U.S. DOLLARS (U.S.$83,333.40). SPSS shall pay an installment on the last
day of each of January, April, July and October of each calendar year following
the Closing Date (each, a "Payment Date"), until the Purchase Price is paid in
full; provided, however, that the first installment shall be paid in advance on
the Closing Date. In no event shall SPSS pay any installment later than fifteen
days after any Payment Date. SPSS shall make such payments by check payable to
"DataStat" at the DataStat address in Section 11.4 or to the order of any other
payee designated by DataStat; provided, however,

                                      - 3 -

<PAGE>   5



that payments made at DataStat's request to any payee other than DataStat shall
be deemed payment to DataStat.

     1.4 Assumption of Liabilities and Obligations. SPSS agrees that, effective
upon the Closing, it shall assume no liabilities and obligations of DataStat
related to the Assets except those accruing after the Closing Date relating to
contracts set forth in SCHEDULE 2.12 which are actually assumed by SPSS
(collectively, the "Assumed Liabilities"). SPSS shall assume only those duties
and obligations of DataStat arising or accruing thereunder after the Closing
Date and SPSS shall have no other duty or obligations. It is expressly
understood and agreed that, except for the Assumed Liabilities, SPSS shall not
be liable for any of the liabilities of DataStat or the VStat business not
constituting Assumed Liabilities (hereinafter, collectively, the "Excluded
Liabilities").

     Unless specifically stated to the contrary, this Agreement shall not
constitute an agreement or an attempted agreement to transfer, sublease or
assign any Assumed Liability or any claim or right arising thereunder or
resulting therefrom if any such attempted transfer, sublease or assignment,
without the consent of any other party thereto, would constitute a breach of
such Assumed Liability or in any way affect the rights of SPSS thereunder.
DataStat shall, between the date hereof and the Closing and, if requested by
SPSS, after the Closing, use all reasonable efforts to obtain the consent of any
such party to the transfer, sublease or assignment thereof by DataStat to SPSS
hereunder in all cases in which such consent is required for transfer, sublease
or assignment. If any such consent is not obtained, or if any attempted
assignment thereof would be ineffective or would affect the rights of DataStat
thereunder such that SPSS would not in fact receive all rights related to an
Assumed Liability, DataStat shall, with the reasonable assistance of SPSS, at
DataStat's expense, perform such Assumed Liability for the account of SPSS or
otherwise cooperate with SPSS at DataStat's expense in any arrangement necessary
or desirable to provide for SPSS the benefits under any such Assumed Liability,
including, without limitation, enforcement for the benefit of SPSS of any and
all rights of DataStat against the other party thereto arising out of the
breach, termination or cancellation of such Assumed Liability by such other
party or otherwise. With respect to those Assumed Liabilities that are license
agreements as to which licensee consent is required for DataStat to assign such
license agreements to SPSS, (i) SPSS shall and hereby does grant DataStat such
licenses as DataStat requires to be in compliance with such license agreements
and (ii) DataStat and SPSS shall enter into good faith negotiations with such
licensee for the assignment of such license agreement to SPSS.

     1.5 Liabilities Not Assumed. Pursuant to Article X, DataStat shall
indemnify, defend and hold SPSS harmless from all Excluded Liabilities and
DataStat's legal fees and other expenses incurred in connection with the
transactions contemplated hereby, and all claims, suits, actions, losses,
damages, costs and expenses (including, without limitation, reasonable
attorneys' fees) arising therefrom or from any failure by DataStat to pay or
discharge such liabilities and obligations as and when they become due.

     1.6 Taxes. SPSS shall not be responsible for, or suffer a reduction in
assets to be received by it for, any income, sales, use, value added, excise or
other taxes of any kind

                                      - 4 -

<PAGE>   6



whether arising before, after or as a result of this purchase, relating solely
to DataStat's ownership of the Assets or the consummation of the transactions
contemplated hereby; provided, however, that SPSS shall be responsible for all
U.S. federal and state taxes which are imposed on SPSS as a result of the
consummation of the transactions contemplated hereby (but not including any U.S.
federal or state taxes imposed on DataStat for activities of DataStat prior to
the Closing Date).


                                   ARTICLE II

                   REPRESENTATIONS AND WARRANTIES OF DATASTAT

     As of the date hereof and as of the Closing Date, DataStat represents and
warrants to SPSS as follows:

     2.1 Organization and Qualification. DataStat is a corporation duly
organized, validly existing and in good standing under the laws of Luxembourg
and has the corporate power and authority to enter into this Agreement, to
consummate the transactions contemplated hereby, to own or lease the Assets
which it presently owns or leases and to carry on its business as presently

and the consummation of the transactions contemplated hereby have been duly and
validly authorized and approved by all necessary action on the part of the Board
of Directors of DataStat and no other proceedings (shareholder, corporate or
otherwise) on the part of either DataStat or its shareholders are necessary to
authorize this Agreement or to consummate the transactions contemplated hereby.
This Agreement and the other agreements contemplated by this Agreement have been
duly and validly executed and delivered by DataStat, and each constitutes a
legal, valid and binding agreement of DataStat, enforceable against DataStat in
accordance with their respective terms, except as their obligations thereunder
may be limited by bankruptcy, insolvency or other similar laws affecting the
enforcement of creditors' rights in general and by general principles of equity
(regardless of whether such enforceability is considered in a proceeding in
equity or at law).

     2.3 Consents and Approvals. There is no authorization, consent, order or
approval of, or notice to or filing with, any individual or entity required to
be obtained or given in order for DataStat to consummate the transactions
contemplated hereby and fully perform its obligations hereunder.

     2.4 Absence of Conflicts. The execution, delivery and performance by
DataStat of this Agreement and the consummation by DataStat of the transactions
contemplated hereby will not, with or without the giving of notice or lapse of
time or both, (i) violate any provision of law, statute, rule or regulation to
which DataStat is subject, (ii) violate any order, judgment or

                                      - 5 -

decree applicable to DataStat, (iii) conflict with or result in a breach or
default under any term or condition of the Articles of Incorporation or By-Laws
of DataStat, or any agreement or other instrument to which DataStat is a party
or by which it is bound, or to which any of the Assets are subject, (iv) result
in the creation or imposition of any lien, pledge, claim, security interest or
encumbrance of any nature whatsoever on the Assets, (v) have a material adverse
effect upon the Assets or the Assumed Liabilities, or (vi) cause, or give any

accelerated.

     2.5 Customer List. Schedule 2.12 contains the list of key DataStat
customers and license fees associated therewith relating to the Assets as of the
Closing Date. DataStat shall provide a complete customer list to SPSS no later
than January 31, 2000.

     DataStat is not in default in respect of any term or condition of any
indebtedness or liability relating to the Assets. There are no facts in
existence and known to DataStat which might reasonably serve as the basis for
any liabilities or obligations of DataStat relating to the Assets not disclosed
in this Agreement, other than liabilities incurred or to be incurred in the
ordinary course of business.

     2.6 Absence of Undisclosed Liabilities. DataStat does not have any
liabilities or obligations relating to the Assets, whether accrued, absolute or
contingent, determined or undetermined, known or unknown, or whether due or to
become due (including, without limitation, obligations as guarantor). DataStat
knows of no basis for the assertion of any claim or liability relating to the
Assets or the business of DataStat, and is not aware of any occurrence or fact
that has or might have an adverse effect upon the Assets or DataStat's business
relating thereto.

     2.7 Absence of Certain Changes or Events. Since November 30, 1999, there
has not been (a) any material damage, destruction or casualty loss to the Assets
(whether covered by insurance or not) outside the ordinary course of business;
(b) any entry into any transaction, commitment or agreement (including, without
limitation, any borrowing) material to the Assets, or relating to the Assets and
outside the ordinary course of business of DataStat; (c) any sale, transfer or
other disposition of the Assets to any party, except for payment of obligations
incurred, and sale of products, in the ordinary course of business consistent
with past practices; (d) any amendment or termination of any material contract
or agreement relating to the Assets to which DataStat is a party or any
termination or waiver of any other rights of value relating to the Assets; (e)
any failure by DataStat to pay its accounts payable or other obligations
relating to the Assets in the ordinary course of business; (f) any pledge of any
of the Assets or any action or inaction which would subject the Assets to any
lien, security interest, mortgage, pledge, claim, charge or other encumbrance of
any kind; (g) the incurrence of any liability or obligation by DataStat related
to the Assets, except for liabilities incurred in the ordinary course of
business; (h) any actual or threatened termination or cancellation of, or
modification or change in, any business relationship with any customer or
customers of DataStat relating to the Assets or other agreement or arrangement
involving or related to the Assets; (i) any other event or condition of any
character which materially and adversely affects

                                      - 6 -

<PAGE>   8



the Assets; or (r) any agreement, whether in writing or otherwise, to take any
action described in this Section 2.7.

     2.8 Personal Property; Inventories. DataStat has good and marketable title
to, and is in possession of or has control over, all of the personal property
comprising the Assets, none of which is held under or subject to any pledge,
lien, lease, encumbrance, conditional sales contract or other security
arrangement.

     2.9 Patents, Trademarks, Etc. SCHEDULE 2.9 hereto contains an accurate and
complete description of all domestic and foreign trademark registrations,
copyright registrations and all applications therefor with respect to VStat (the
"Registered Intellectual Property"), presently owned or held by DataStat or
under which DataStat owns or holds any license, or in which DataStat owns or
holds any direct or indirect interest. To the best knowledge of DataStat, no
VStat products manufactured, distributed or sold by DataStat, nor any of
DataStat's activities, conflict with, infringe or otherwise violate any patents,
trademarks or copyrights, or any other rights, of any individual or entity.
DataStat has the sole and exclusive right to use, has the right and power to
sell, and has taken reasonable measures to maintain and protect the Intellectual
Property (as defined herein); no claims have been asserted by any individual or
entity with respect thereto or challenging or questioning the validity or
effectiveness of any license or agreement with respect thereto, and, to the best
knowledge of DataStat, there is no valid basis for any such claim. DataStat is
not using confidential information or trade secrets of any former employer of
any past or present employees engaged in DataStat's business. The items
described in SCHEDULE 2.9 and DataStat's other intellectual property relating to
VStat (including, without limitation, trademarks, service marks, logos, trade
names, assumed names, trade secrets, know-how, technology, inventions,
processes, designs and copyrights) (collectively, "Intellectual Property") are
adequate to conduct DataStat's business with respect to VStat as presently
conducted. Upon consummation of the transactions contemplated hereby, SPSS will
acquire good and marketable title to all of the Intellectual Property and the
goodwill associated therewith, subject to the restrictions listed in
Section 1.1.

     2.10 Employees. All personnel, including employees, agents, consultants and
contractors, who have contributed to or participated in the conception and
development of the Intellectual Property on behalf of DataStat have executed
appropriate instruments of assignment, which are still in full force and effect,
in favor of DataStat, as assignee, that have conveyed to DataStat full,
effective and exclusive ownership of all intellectual property thereby arising.
DataStat does not own or have any right, license or interest, whether as a
licensee, licensor or otherwise, in any copyrights, patents, applications for
copyrights or patents, trade secrets, inventions, processes and designs or in
any trademarks, service marks, trade names, or applications for them related to
VStat.

     2.11 Source Code. DataStat owns all rights, title and interest in and to
the source code for VStat and has not distributed any copies of such source code
to any third parties, and DataStat has not agreed to pay to any individual or
entity any royalty, commission or other amount

                                      - 7 -

<PAGE>   9



on account of sales of VStat. DataStat owns all rights, title and interest in
and to all localizations and translations of manuals and other technical
documentation.

     2.12 Contracts and Commitments.

         (a) Other than standard form customer contracts and verbal contracts,
entered into in the ordinary course of business, each as set forth in SCHEDULE
2.12, DataStat is not a party to any agreements, contracts, guarantees,
commitments, restrictions or instruments of any kind relating to the Assets
("Contracts"). True and correct copies of all key Contracts have been made
available to SPSS at a reasonable time prior to Closing. All of the Contracts
are valid and binding obligations of DataStat, enforceable in accordance with
their respective terms to the extent permitted by applicable law, and are in
full force and effect and DataStat is in compliance therewith. None of the
Contracts has, or may to the best of DataStat's knowledge have, a material
adverse effect on the Assets. No other party to any of the Contracts is in
default or breach thereof. DataStat has not agreed with any customer or
distributor to make any variation in any such contract which could have a
material adverse effect on the Assets.

         (b) DataStat is not in default, and there is no basis for any valid
claim of default, in any respect under any of the Contracts.

     2.13 Licenses and Royalties. DataStat is not a licensee under any license
with respect to the Assets, including, without limitation, licenses with respect
to source codes used or to be used in VStat, and does not have an obligation to
pay royalties to any third party in connection therewith, and DataStat has not
granted to any individual or entity any rights with respect to the source codes
for VStat.

     2.14 Adequacy of Documentation. The Technical Documentation includes the
source code, system documentation, statements or principles of operation, and
schematics for VStat currently maintained or licensed by DataStat, as well as
any pertinent commentary or explanation that may be necessary to render such
materials understandable and usable by a trained computer programmer familiar
with the relevant compilers, tools and platform.

     2.15 Third-Party Components in Software Programs. VStat and the Technical
Documentation contain no other programming or materials in which any third party
may claim superior, joint or common ownership, including any right or license,
and, do not contain derivative works of any programming or materials not owned
in their entirety by DataStat.

     2.16 Third-Party Interests or Marketing Rights in VStat Software Programs.
All of DataStat's standard form customer contracts constitute only end-user
agreements, each of which grants the end-user thereunder solely the
non-exclusive right and license to use VStat and related user documentation, for
internal purposes only. There are no contracts, agreements, licenses or other
commitments or arrangements in effect with respect to the development,
marketing, distribution, licensing, or promotion of VStat, the Technical
Documentation, or DataStat's

                                      - 8 -

Intellectual Property with any independent salesperson, distributor,
sublicensor, or other remarketer or sales organization.

     2.17 No Virus Warranties. DataStat represents and warrants that VStat, as
delivered to SPSS, shall be free of any passwords, keys, security devices or
trap doors, and any computer instructions (including, but not limited to,
computer instructions commonly referred to as Trojan Horses, anomalies, worms,
self-destruct mechanisms, or time/logic bombs) which are intended to interfere
with or frustrate the use of the software products, any portion thereof, or
other software or computer hardware, whether or not currently in effect with
respect to any copy of DataStat's software products.

     2.18 Purchased Software; Physical Media. The software purchased as part of
the Assets, other than that currently under development (the "Purchased
Software"), will operate in accordance with the Technical Documentation. The
Purchased Software and any licenses or other rights connected therewith, express
or implied, will not infringe any other person's intellectual property rights
and DataStat has full right and authority to sell and assign the Purchased
Software, and the rights connected therewith to SPSS. Each copy of Purchased
Software delivered by DataStat is and will be free from physical defects in the
media that tangibly embodies the copy.

     2.19 Product Warranties and Liabilities. DataStat has not given or made any
express or implied warranties to third parties with respect to any Assets
licensed or sold or services performed by it related thereto, except for the
limited warranties stated in DataStat's standard form customer contracts, in the
forms attached to SCHEDULE 2.12, with modifications that, in the aggregate,
would not have a material adverse effect on the Assets. DataStat does not have
any knowledge of any fact or of the occurrence of any event forming the basis of
any present or future claim against DataStat relating to the Assets whether or
not fully covered by insurance, for liability on account of products liability
or on account of any express or implied product warranty, except for warranty
obligations and product returns in the ordinary course of business.

     2.20 Litigation and Administrative Proceedings. There is no claim, action,
suit, proceeding or investigation in any court or before any governmental or
regulatory authority pending or threatened against or affecting DataStat
relating to the Assets or which seeks to enjoin or obtain damages in respect of
the transactions contemplated hereby. DataStat does not know or have reason to
know of any basis for any such claim, action, suit, proceeding or investigation.

     2.21 Tax Matters. None of the Assets is subject to any lien or other
encumbrance as a result of unpaid taxes and SPSS will not become liable for any
taxes as a result of this purchase, relating solely to DataStat's ownership of
the Assets or the consummation of the transaction contemplated hereunder.
Notwithstanding the foregoing, DataStat makes no representation or warranty as

certificate, list or other writing furnished to SPSS pursuant to the provisions
hereof, contains any untrue statement of a material fact or omits to state a

                              COVENANTS OF DATASTAT

     DataStat covenants as follows:

     4.1 Tax Matters. DataStat will timely pay or satisfy all liabilities
imposed on DataStat by any taxing authority under any tax statute that may be
due by DataStat as a result of the sale of the Assets hereunder. SPSS shall be
liable for any tax liability that may be imposed on SPSS solely as a result of
SPSS's acquisition of the Assets hereunder; provided, however, that DataStat
shall be liable for any taxes accruing or arising prior to the Closing Date and
relating to the Assets.

     4.2 Post-Closing Access to Information. For a period of three (3) years
after the Closing, DataStat shall not dispose of any books, records, documents
or information relating in whole or part to the Assets or otherwise to the VStat
business of DataStat without first giving notice to SPSS and permitting SPSS to
copy, without cost, those portions of such books and records which relate to the
Assets or otherwise to the VStat business as SPSS may select. During such three
(3)- year period, DataStat shall permit SPSS to examine and make copies, at
SPSS's expense, of such books, records, documents or information for any
reasonable purpose, including but not limited to any litigation commenced
against SPSS or any affiliate of SPSS or the preparation of income or other tax
returns or in connection with any administrative or regulatory proceedings or
actions.

     4.3 Right of Endorsement. Upon the Closing and thereafter, SPSS shall have
the right and authority to endorse, without recourse, the name of DataStat on
any check or any other evidence of indebtedness received by SPSS and to which it
is entitled on account of any receivable or other Asset transferred by DataStat
pursuant hereto, and DataStat shall deliver to SPSS at the Closing documents
sufficient to permit SPSS to deposit such checks or other evidences of
indebtedness in bank accounts in the name of SPSS.

     4.4 Accounts Receivable. After the Closing, DataStat shall promptly remit
to SPSS all the proceeds of any checks and other payments for accounts
receivable belonging to SPSS under this Agreement and coming into the possession
of DataStat. DataStat shall also ensure that

                                     - 12 -

<PAGE>   14



payments received by DataStat on accounts receivables can be identified as for
the account of SPSS or for the account of DataStat.

     4.5 Further Assurances. After the Closing, DataStat shall within a period
of one (1) year, at the request of SPSS and without further cost or expense to
SPSS, execute and deliver such other documents and take such other actions as
shall be reasonably necessary or appropriate to consummate fully the
transactions contemplated hereby.

     4.6 Discontinuance of Use. Upon Closing, DataStat will discontinue use of
the name "VerbaStat" and of the prefix "Verba" or any confusingly similar part
of the name except for purposes of collecting unpaid accounts receivable related
to the Assets.

     4.7 Consents. DataStat will use all reasonable efforts to obtain the
express written consent of all third parties necessary to assign any Contracts
included in the Assets. If any third party withholds consent or DataStat
receives royalties or payments on account of such Contracts after Closing,
DataStat will hold all such amounts in trust for SPSS and promptly pay same to
SPSS. DataStat will indemnify and hold SPSS harmless from and against any loss
suffered by SPSS as a result of DataStat's failure to obtain any necessary
consent to the assignment of such Contracts.

     4.8 Non-Competition; Confidentiality.

         4.8.1 DataStat understands and agrees that the business of SPSS, among
other things, concerns proprietary computer software programs and related
documentation which will include, after the acquisition contemplated by this
Agreement, the proprietary computer software programs and related documentation
constituting a portion of the Assets. DataStat understands that in the course of
its dealings with SPSS, SPSS and/or its subsidiaries or affiliates may provide
DataStat with, or access to, its software (including, without limitation, source
listings therefor), as well as confidential and/or proprietary prospect and
customer lists, data, research, specifications, memoranda, files, records,
plans, concepts, flow charts, drawings, designs, descriptions, formula tions,
trade secrets and other confidential and/or proprietary information and
property, including but not limited to, information regarding SPSS operations,
businesses, affairs, management and market structure (all of the foregoing
collectively referred to as the "Confidential Property"). Confidential Property
shall not, however, include any information which (i) was publicly known and
made generally available in the public domain prior to the time of disclosure by
the disclosing party; (ii) becomes publicly known and made generally available
after disclosure by the disclosing party to the receiving party through no
action or inaction of the receiving party; (iii) is already in the possession of
the receiving party at the time of disclosure by the disclosing party as shown
by the receiving party's files and records immediately prior to the time of
disclosures; (iv) is obtained by the receiving party from a third party without
a breach of such third party's obligations of confidentiality; (v) is
independently developed by the receiving party without use of or reference to
the disclosing party's Confidential Property, as shown by documents and other
competent evidence in the receiving party's possession; or (vi) is required by
law to be disclosed by the receiving party, provided that the

                                     - 13 -

<PAGE>   15



receiving party gives the disclosing party prompt written notice of such
requirement prior to such disclosure and assistance in obtaining an order
protecting the information from public disclosure.

         4.8.2 DataStat will regard and preserve as confidential and as trade
secrets all of the Confidential Property. Except as may be required by law, any
governmental agency or under the Securities Exchange Act of 1934, as amended
(the "Exchange Act"), DataStat will not, directly or indirectly, communicate or
divulge to, or use for the benefit of itself or any other person, firm,
association or corporation, without the prior written consent of SPSS, any
Confidential Property. The Confidential Property shall remain the sole and
exclusive property of SPSS, and upon request by SPSS for any reason whatsoever,
DataStat shall promptly return any and all Confidential Property in its
possession or control to SPSS.

         4.8.3 DataStat shall have no right, title or interest of any kind or
nature in any of the Confidential Property or any proceeds therefrom.

         4.8.4 DataStat hereby further covenants and agrees that during the Non-
Compete Period (as hereinafter defined) DataStat will not directly or indirectly
(whether through a partnership of which DataStat is a partner or through any
other individual or entity in which DataStat has any interest, legal or
equitable, or otherwise), engage in the software business being acquired by SPSS
pursuant to this Agreement (limited to software for data entry, classification
and coding of open-ended responses in the framework of the survey process (the
"VStat Business")) as in existence or under development on the Closing Date, and
directly or indirectly (whether through a partnership of which DataStat is a
partner or through any other individual or entity in which DataStat has any
interest, legal or equitable, or otherwise) solicit or otherwise be involved
with any customers or clients of SPSS or of the VStat Business existing on the
date of acquisition of the VStat Business by SPSS in any transactions which are
in competition with the VStat Business at any time during the Non-Compete
Period, or directly or indirectly (whether through a partnership of which
DataStat is a partner or through any other individual or entity in which
DataStat has any interest, legal or equitable, or otherwise), assist any person
in the development, programming, servicing, maintenance, manufacture, sale,
licensing, distribution or marketing (including, without limitation, giving away
software) of statistical software and related products in competition with
products of the VStat Business in the United States of America or any other
country in which SPSS or any of its affiliates is doing business.

     As used herein, the term "Non-Compete Period" shall mean a period of two
(2) years after the Closing Date.

         4.8.5 During the Non-Compete Period, DataStat will not employ, solicit
for employment, or advise or recommend to any other person that they employ or
solicit for employment, any employee of SPSS.

     DataStat further agrees that the limitations set forth herein (including,
without limitation, any time or territorial limitations) are reasonable and
properly required for the adequate

                                     - 14 -

<PAGE>   16



protection of the VStat Business. In the event any such territorial or time
limitation is deemed to be unreasonable by a court of competent jurisdiction,
DataStat agrees to the reduction of the territorial or time limitation to the
area or period which such court shall have deemed reasonable. It is understood
and agreed that the covenants made by DataStat herein relating to
confidentiality shall survive the expiration or termination of this Agreement,
and that the covenants made by DataStat herein relating to non-competition shall
survive the Closing of this Agreement.

     4.9 Equitable Relief. DataStat understands that a breach by it of any
provision of this Agreement may cause substantial injury to SPSS which may be
irreparable and/or in amounts difficult or impossible to ascertain, and that in
the event DataStat breaches any provision of this Agreement, SPSS shall have, in
addition to all other remedies available in the event of a breach of this
Agreement, the right to injunctive or other equitable relief. Further, DataStat
acknowledges and agrees that the restrictions and commitments set forth in this
Agreement are necessary to protect the legitimate interests of SPSS and are
reasonable in scope, area and time, and that if, despite this acknowledgment and
agreement, at the time of the enforcement of any provision of this Agreement a
court of competent jurisdiction shall hold that the period or scope of such
provision is unreasonable under the circumstances then existing, the maximum
reasonable period or scope under such circumstances shall be substituted for the
period or scope stated in such provision.

     4.10 Verbal Agreements. After Closing, DataStat shall assist SPSS in
obtaining written contracts between SPSS and those customers referenced in
Schedule 2.12 as to which verbal agreements exist.

                                    ARTICLE V

                                COVENANTS OF SPSS

     SPSS covenants as follows:

     5.1 Retention of Records. After the Closing, SPSS will retain all of
DataStat's books and records relating to the Assets which come into SPSS's
possession in accordance with SPSS's policies for retention of its own books and
records. SPSS will provide DataStat access to such books and records concerning
periods prior to the Closing in SPSS' possession upon reasonable notice, during
SPSS's regular business hours and at reasonable intervals.

     5.2 Further Assurances. After the Closing, SPSS shall from time to time, at
the request of DataStat and without further cost or expense to DataStat, execute
and deliver such other documents and take such other actions as shall be
reasonably necessary or appropriate to consummate fully the transactions
contemplated hereby.

and representatives with a need to know such Confidential Information in order
to consummate the transactions contemplated hereby) or (ii) use any Confidential
Information for any purpose other than consummating the transactions

when and to the extent it has actual knowledge of that liability, and DataStat
shall be solely responsible for the satisfaction of the liability.

     10.4 Indemnification Procedure. (a) An indemnified party under Section 10.2
of this Agreement shall give prompt written notice to DataStat (when and to the
extent that the indemnified party has actual knowledge thereof) of any
condition, event or occurrence or the commencement of any action, suit or
proceeding for which indemnification may be sought, and DataStat, through
counsel reasonably satisfactory to the indemnified party, shall assume the
defense thereof or other indemnification obligation with respect thereto;
provided, however, that any indemnified party shall be entitled to participate
in any such action, suit or proceeding with counsel of its own choice but at its
own expense; and provided, further, that any indemnified party shall be entitled
to participate in any such action, suit or proceeding with counsel of its own
choice at the expense of DataStat, if, under applicable canons of ethics, joint
representation of DataStat and SPSS presents a conflict of interest. In any
event, if DataStat fails to assume the defense within a reasonable time, the
indemnified party may assume such defense or other indemnification obligation
and the reasonable fees and expenses of its attorneys will be covered by the
indemnity provided for hereunder. No action, suit or proceeding for which
indemnification may be sought shall be

                                     - 20 -

<PAGE>   22



compromised or settled in any manner which might adversely affect the interests
of DataStat without the prior written consent of DataStat (which shall not be
unreasonably withheld); provided, however, that SPSS may settle any claim or
cause of action without DataStat's consent, but in such case DataStat shall not
be required to reimburse SPSS for its Losses. Notwithstanding anything in this
Section 10.4 to the contrary, DataStat shall not, without the prior written
consent of the indemnified party, (i) settle or compromise any action, suit or
proceeding or consent to the entry of any judgment which does not include as an
unconditional term thereof the delivery by the claimant or plaintiff to the
indemnified party of a written release from all liability in respect of such
action, suit or proceeding or (ii) settle or compromise any action, suit or
proceeding in any manner that may materially and adversely affect the
indemnified party other than as a result of money damages or other money
payments. DataStat shall pay all expenses, including attorneys' fees, that may
be incurred by any indemnified party in enforcing the indemnity provided for
hereunder.

     10.5 Indemnification by SPSS. SPSS agrees to indemnify and hold DataStat
and its affiliates and the respective officers, directors, employees, agents and
representatives of each of the foregoing harmless from and against any and all
Losses relating to (i) any and all of the Assumed Liabilities, except to the
extent that the Losses relate to a period prior to the Closing Date; (ii) any
breach of any representation or warranty of SPSS set forth in Article III hereof
or any related schedule, or set forth in any closing certificate or other
document entered into or delivered by SPSS in connection with this Agreement;
(iii) any breach of any covenant or obligation of SPSS contained in this
Agreement or in any other closing document; (iv) any fraudulent representation
or intentional misrepresentation on the part of SPSS; (v) any intentional or
fraudulent breach by SPSS, of any warranty, representation, agreement, covenant
or obligation made under this Agreement; (vi) any material misrepresentation
contained in, or material omission from, any provisions of this Agreement or
instruments furnished or to be furnished hereunder; and (vii) any liability or
obligation arising out of or related to the Assumed Liabilities after the
Closing Date or the use of the Assets after the Closing Date, unless the claim
or cause of action with respect thereto arises out of or is related to actions
or omissions of DataStat prior to the Closing Date.

     10.6 Indemnification Procedure. (a) An indemnified party under Section 10.5
of this Agreement shall give prompt written notice to SPSS (when and to the
extent that the indemnified party has actual knowledge thereof) of any
condition, event or occurrence or the commencement of any action, suit or
proceeding for which indemnification may be sought, and SPSS, through counsel
reasonably satisfactory to the indemnified party, shall assume the defense
thereof or other indemnification obligation with respect thereto; provided,
however, that any indemnified party shall be entitled to participate in any such
action, suit or proceeding with counsel of its own choice but at its own
expense. In any event, if SPSS fails to assume the defense within a reasonable
time, the indemnified party may assume such defense or other indemnification
obligation and the reasonable fees and expenses of its attorneys will be covered
by the indemnity provided for in Section 10.5. No action, suit or proceeding for
which indemnification may be sought shall be compromised or settled in any
manner which might adversely affect the interests of SPSS without the prior
written consent of SPSS (which shall not be unreasonably withheld).
Notwithstanding anything in this Section 10.6 to the contrary, SPSS shall not,
without the prior

                                     - 21 -

<PAGE>   23



written consent of the indemnified party, (i) settle or compromise any action,
suit or proceeding or consent to the entry of any judgment which does not
include as an unconditional term thereof the delivery by the claimant or
plaintiff to the indemnified party of a written release from all liability in
respect of such action, suit or proceeding or (ii) settle or compromise any
action, suit or proceeding in any manner that may materially and adversely
affect the indemnified party other than as a result of money damages or other
money payments. SPSS shall pay all expenses, including attorneys' fees, that may
be incurred by any indemnified party in enforcing the indemnity provided for in
Section 10.5.

     10.7 Offset Against Unpaid Amounts. Without limiting such other rights as
SPSS may have and subject to the survival period of the representation and
warranties contained in Section 10.1, if, prior to the time that any payment of
the Purchase Price is to be delivered, SPSS has learned of a breach of any
representation, warranty, covenant or agreement of DataStat contained in this
Agreement, SPSS in its sole discretion may by written notice deduct from the
amount of such payment otherwise owed an amount equal to the aggregate of (a)
the amount necessary to cure or make it whole for such breach or (b) the amount
of losses, damages and expenses incurred or demonstrably in prospect of being
incurred in connection with or caused by such breach.

respect to, any subsequent or other failure. Any waiver must be in writing and
duly executed by the appropriate parties.

     11.3 Expenses. Whether or not the transactions contemplated by this
Agreement shall be consummated, the parties hereto agree that all fees and
expenses incurred by DataStat, on the one hand, and SPSS, on the other, in
connection with this Agreement, and the transactions and other actions
contemplated thereby or taken in connection therewith, shall be borne by
DataStat, and by SPSS, respectively, including, without limitation, all fees of
counsel and accountants.
