                 2007 EXECUTIVE INCENTIVE CASH COMPENSATION PLAN
                          (measured and paid quarterly)

PARTICIPANTS: SPSS Executive Officers

OBJECTIVE:    To provide cash incentives that reward executives for the delivery
              of superior corporate performance in achieving specific measurable
              results that drive growth in stockholder value.

PAID:         As soon as practical after the close of each fiscal quarter, after
              approval by the Compensation Committee.

2007 TARGETS: Executive's Incentive Cash Target will be based on Revenue (30%) /
              EPS (70%) - with the exception of the Senior Vice President -
              Worldwide Sales whose target will be based on Revenue (70%) / EPS
              (30%). All amounts will be measured on a GAAP reported basis.

              - REVENUE: The quarterly revenue target is defined as the
                         applicable quarterly revenue target set forth in the
                         2007 Business Plan as approved by the Board of
                         Directors and as re-affirmed or adjusted each quarter
                         by the Compensation Committee of the Board.

              - EPS:     The quarterly earnings per share target is defined as
                         the applicable quarterly earning per share targets set
                         forth in the 2007 Business Plan as approved by the
                         Board of Directors and as re-affirmed or adjusted each
                         quarter by the Compensation Committee of the Board.

              The Compensation Committee may adjust the Plan targets and/or
              payment calculation, as necessary, to insure comparability or to
              recognize the positive or negative impact of any items deemed to
              be inconsistent with the originally approved Plan such as
              unanticipated organizational changes (including acquisitions and
              divestitures), one-time, unusual, prior year items or
              non-operating items impacting the GAAP reported Revenue and/or
              EPS.

CALCULATION AND PAYMENT AMOUNT:

              - REVENUE: An executive's cash incentive will be paid at 100% of
                         executive's applicable approved incentive compensation
                         for achievement of 100% of the Revenue target, plus or
                         minus 10% for each $100,000 difference from Revenue
                         target (calculated proportionally).

              - EPS:     An executive's cash incentive will be paid at 100% of
                         executive's applicable approved incentive compensation
                         for achievement of 100% of EPS target.



                         -    An executive's cash incentive will be paid at 50%
                              of executive's applicable approved incentive
                              compensation for achievement of $0.01 below EPS
                              target and no payment for achievement of EPS
                              target $0.02 or more below EPS target. (Incentive
                              payment will be calculated proportionally between
                              $0.01 and $0.02 below target).

                         -    For the achievement of EPS above target amount,
                              executive's cash incentive will be paid at 100%
                              plus an additional payment from the "Incentive
                              Pool" (as defined below) equal to the executive's
                              relative percentage share (calculated as the
                              executive's approved incentive compensation
                              divided by the sum of the approved incentive
                              compensation for all individuals participating in
                              this Executive Incentive Cash Compensation Plan)
                              times the amount of the Incentive Pool.

                         -    The "Incentive Pool" will be equal to one-third
                              the amount that net income exceeds the net income
                              equivalent to the EPS target. (Note: payments
                              relative to the Incentive Pool will not be in
                              excess of incentive pool accrual recorded.)

              -    The final calculation and approval of payment of incentives
                   to executives is at the sole discretion and approval of the
                   Compensation Committee of the Board of Directors.
