                  i.       In addition to the requirements set forth above, in
                           order to comply with the Irish requirements, you must

                           any necessary Irish export licenses.

10.      PAYMENTS AND BILLING. We will bill you for fees as specified in the
         price lists attached to the Statements of Work or, when applicable, our
         proposal to you and payment is due at payment terms of Net 45 days.

         a.       Fees specified in the Statement of Work or our proposal do not
                  include transportation charges (unless otherwise stated in the
                  applicable price list) or any taxes, duties or other charges
                  imposed by any governmental authority that may be due. You
                  will be responsible for payment of any such transportation
                  charges, taxes, duties or other charges. Prior to any
                  Products, Optional Publications or other materials being
                  distributed to an end user, you will provide us with an
                  appropriate resale certificate, and instruct us not to charge
                  sales tax since you will charge any sales tax due on your
                  transaction with your end user customer.

         b.       Below are the parameters under which prices can change for
                  each Statement of Work implemented during the term of this
                  Agreement:

                  i.       Prices quoted in the initial Statement of Work,
                           except Publications, will be frozen for 12 months
                           from signing the initial Statement of Work.

                  ii.      Any change in Media volumes after implementation of a
                           Statement of Work, will be priced from the applicable
                           price list or our proposal to you, if volumes
                           warrant.

                  iii.     After the initial 12-month period that this Agreement
                           is in effect, we may increase prices in a Statement
                           of Work, other than Publications which are covered in
                           Section 7.d) below. However, except as provided
                           below, prices initially applicable to any Statement
                           of Work, other than Publications, will not increase
                           during the second 12-month period that this Agreement
                           is in effect by more than the actual increase of the
                           Manufacturing Index found within the Employment Cost
                           Indexes and Levels, as published by the U.S.
                           Department of Labor during that period. As an
                           exception to this increase limit, we may increase
                           prices in a Statement of Work to reflect labor cost
                           increases imposed on us by federal or state law or
                           regulation. Any such price increase will become
                           effective on the same date that the mandated labor
                           cost increase first affects us.

11.      PUBLICATIONS.

         a.       Pricing for Publications is based on original Publication
                  specifications provided by you. However,

                  iii.     prices may be adjusted any time there are changes in
                           Publication specifications.

         b.       The foregoing price parameters assume manufacturing and
                  distribution work to be done in the United States.

12.      LICENSE. You grant to us a no-charge, royalty-free, non-transferable,
         non-exclusive license to reproduce and distribute copies of your
         Programs, Publications and other materials to the extent necessary for

                           AND FITNESS FOR A PARTICULAR PURPOSE.

14.      INDEMNIFICATION. You will indemnify, defend, and hold us harmless
         against any claims, losses, and expenses, including attorney fees and
         other costs of litigation, based on or arising out of any third party
         claim that any Product, Optional Publication or other material
         infringes any third party intellectual property rights or for any
         breach by your of your warranties in this Agreement.

         a.       BANTA will indemnify, defend, and hold you harmless against
                  any claims, losses, and expenses, including attorney fees and
                  other costs of litigation, based on or arising out of any
                  third party claim that Banta has introduced any routine,
                  device, code or instructions (including any code or
                  instructions provided by third parties) or other undisclosed
                  feature, including, without limitation, a time bomb, virus,
                  software lock, drop-dead device, malicious logic, worm, Trojan
                  horse, bug, error, defect or trap door, that is capable of
                  accessing, modifying, deleting, damaging, disabling,
                  deactivating, interfering with, or otherwise harming the
                  software program.

         b.       These indemnities are conditioned upon prompt written notice
                  to you of the claim or proceeding subject to indemnification;
                  cooperation by us at your expense in the defense and
                  settlement of any such claim; and mutual consent to settlement
                  or resolution of any such claim, which consent shall not
                  unreasonably be withheld.

15.      INFORMATION. Terms for exchange of confidential information will be
         handled according to the Confidential Non-Disclosure Agreement which
         you and we will sign at the same time as this Agreement is signed.

         a.       For all information which does not meet the definition of
                  "Confidential Information" under the Confidential
                  Non-Disclosure Agreement, no obligation of confidentiality of
                  any kind is assumed by, or shall be implied against, either
                  party with respect thereto regardless of whether the
                  non-confidential information is received in the Programs,
                  Publications or some other form and whenever received from the
                  other party under this Agreement or in activities related
                  hereto. Either party shall be free to use or disclose any
                  information concepts, ideas, know-how, or techniques contained
                  in non-confidential information received under this Agreement,
                  subject only to valid copyrights and patents owned or licensed
                  by the party providing such information.

16.      TERMS AND TERMINATION. Unless otherwise terminated as provided herein,
         this Agreement shall be in effect from the date first written above and
         shall remain in force for three (3) years. This Agreement shall
         automatically renew thereafter for successive periods of one (1) year
         each unless either of us give notice of its intent to terminate this
         Agreement not less than one hundred eighty (180) days prior to the
         expiration of the initial term or any renewal term. Not less than sixty
         (60) days prior to the end of the initial term or the renewal term then
         in effect, we will propose to you the pricing to be applicable to each
         Statement of Work during the next renewal term. Unless you object to
         our proposed pricing within ten (10) days after receipt, the proposed
         pricing will become effective as of the beginning of the next renewal
         term. If you do object within the ten (10) day period, we will
         negotiate


<PAGE>
         mutually acceptable pricing with you, but if prices have not been
         agreed to by the date on which notice of termination must be given, we
         will either agree to terminate the Agreement or continue the Agreement
         on a day-to-day basis while price negotiations continue.

17.      TERMINATION.

         a.       TERMINATION FOR CONVENIENCE. You may terminate this Agreement
                  for convenience or for any other reason upon 180 days' prior
                  written notice to us. We may terminate this Agreement for
                  convenience or for any other reason upon 180 days' prior
                  written notice to you. If we terminate this Agreement for any
                  reason other than as specified in Section 12.b), then during
                  the 180-day notice period we will assist you in finding a new
                  vendor and will make every reasonable effort to make the
                  transition from us to your new vendor a smooth one.

         b.       TERMINATION FOR CAUSE. Either party may terminate this
                  Agreement by written notice if the other materially breaches
                  its obligations under this Agreement. Such a termination
                  notice must specifically identify the breach (or breaches)
                  upon which it is based and will become effective 180 days
                  after the notice is received by the other party, unless the
                  breach(es) is (are) corrected during the 180 days.

         c.       TERMINATION OF STATEMENTS OF WORK AND PURCHASE ORDERS. You may
                  terminate a Statement of Work on 180 days' written notice to
                  us or an individual purchase order on 30 days' written notice
                  to us. We may terminate a Statement of Work on 180 days'
                  written notice to you or an individual purchase order on 30
                  days' written notice to you if you do not meet your
                  obligations. Upon termination, we will stop our work in an
                  orderly manner as soon as practical.

18.      SURVIVAL.

         a.       Neither termination or expiration of this Agreement, any
                  Statement of Work or any purchase order shall have any effect
                  upon the respective rights and liabilities of the parties in
                  connection with any work we previously performed or that were
                  in process on the date termination became effective. In
                  particular, you agree to pay us for all services we provide,
                  all costs incurred, in connection with services or Products,
                  Optional Publications or other materials we provide, and any
                  Products, Optional Publications or other materials we deliver
                  through the termination of the Agreement, Statement of Work,
                  or purchase order, as the case may be. Payment includes any
                  charges we incur in terminating subcontracts or orders for raw
                  materials.

         b.       Any terms or this Agreement which by their nature extend
                  beyond its termination, including the provisions of Sections
                  9, 10, 11, and 13, will remain in effect until fulfilled, and
                  apply to respective successors and assignees.

19.      GENERAL.

         a.       FREEDOM OF ACTION. Nothing in this Agreement shall prohibit or
                  strict either party from independently developing, acquiring,
                  and marketing products, services, and other materials which
                  are competitive with the products, services, or materials of
                  the other party.

         b.       LIMITATIONS. We shall have no liability to you:

                  i.       For any third party actions which violate your
                           intellectual property rights, or
<PAGE>

                  ii.      For non-payment of license fees or service charges by
                           others.

         c.       Notwithstanding anything herein to the contrary, in no event
                  shall either party be liable to the other for any indirect,
                  incidental, special, punitive, or consequential damages,
                  including lost profits, regardless of the form of the action,
                  whether in contract or tort (including negligence), provided
                  however that Banta agrees to pay SPSS for any incidental,
                  consequential, special or other indirect damages sustained by
                  SPSS during the period from January 3, 2006 to the expiration
                  or termination of this agreement, including any applicable
                  renewal terms, as a result of Banta's or its subcontractor's
                  breach of Section 13.c.ii of this Agreement up to a limit of
                  $1,000,000 in aggregate during such period. No action,
                  regardless of form, arising out of this Agreement may be
                  brought by either party more than two years after the cause of
                  action has accrued.

         d.       CHOICE OF LAW. This Agreement will be governed by the
                  substantive laws of the State of Illinois.

         e.       ENTIRE AGREEMENT. This Agreement, together with any Statements
                  of Work entered into by the parties from time to time during
                  the term hereof, and purchase orders issued to us hereunder,
                  all of which are incorporated into this Agreement by this
                  reference, are the complete agreement regarding these
                  transactions, and replace any prior oral or written
                  communication between us. If there is a conflict between terms
                  in this Agreement and those in a Statement of Work, the terms
                  in the Statement of Work shall prevail over the terms of this
                  Agreement; provided, however, that all shipments of Products,
                  Optional Publications or other materials shall be subject to
                  Section 6 unless we agree to the contrary in a written
                  document which specifically states that Section 6 does not
                  apply to a particular shipment described therein and which is
                  signed by our authorized representative.

         f.       SEVERABILITY. If any provision of this Agreement is held to be
                  illegal, unenforceable, or in conflict with any law of any
                  governmental entity with jurisdiction over this Agreement, the
                  other portions shall remain valid and enforceable.

         g.       AMENDMENTS IN WRITING. No amendment, modification or waiver of
                  any provision of this Agreement shall be effective unless it
                  is in a writing executed by authorized representatives of both
                  parties. No failure or delay by either party in exercising any
                  right, power or remedy will operate as a waiver of any such
                  right, power or remedy.

         h.       NOTICE. Any notices required or permitted under this Agreement
                  shall be made by fax, email, express overnight courier
                  service, charges paid by shipper, or certified or registered
                  mail, postage prepaid and return receipt requested, provided
                  that the same is addressed to the party to be notified at the
                  following address (or such other address, or to the attention
                  of such other person, as may be hereinafter designated in
                  writing by the party to be notified):

                  to fulfill its obligations under this Agreement, if such
                  failure is caused by flood, extreme weather, fire, or other
                  natural calamity, acts of governmental agency, or similar
                  causes beyond the control of such party.
