<PAGE>

            Earnings and EPS are calculated after giving effect to any bonus
            that is paid or proposed to be paid under this Plan.

      3.9   Revenue means total revenues as reported in the consolidated
            quarterly financial statements of the Company.

4.    ELIGIBILITY AND PARTICIPATION

      Executives eligible for bonuses under the Plan shall be those individuals
      specified in Appendix I.

5.    BONUS MECHANISM

      5.1   The amount of on-target bonus that is paid will be determined as
            follows:

            (a)   Each participant is eligible to earn forty (40%) percent of
                  the on-target bonus based on the achievement of quarterly
                  goals and sixty (60%) percent based on the achievement of
                  annual goals. The quarterly and annual Revenue and EPS goals
                  are stated in Appendix II.

            (b)   The percentage of the on-target bonus described in Appendix I
                  earned by each Participant on achievement of the amounts
                  stated in Appendix II in respect of each Plan Quarter is:

                  (i)      Q1      5% based on Revenue, 5% based on Earnings
                  (ii)     Q2      5% based on Revenue, 5% based on Earnings
                  (iii)    Q3      5% based on Revenue, 5% based on Earnings
                  (iv)     Q4      5% based on Revenue, 5% based on Earnings

                                   40% in total

            In the event that the achievement for Revenue in any quarter is less
            than the amount stated in Appendix II for that quarter, but is equal
            to or greater than 97.5% of such amount, then a partial bonus shall
            be paid to each Participant. The partial bonus shall be equal to the
            actual amount of Revenue achieved for the quarter divided by the
            amount of the Revenue goal for the quarter as stated in Appendix II
            times the on-target bonus the participant would otherwise have
            earned for the Revenue component (i.e. 5% of total on-target bonus).
            Achievement for Earnings must be at 100% to be eligible for payout
            on that component. No incremental bonus is payable to any
            participant for achievement above 100% in any quarter.

            (c)   The percentage of the on-target bonus described in Appendix I
                  earned by each Participant on achievement of the amounts
                  stated in Appendix II in respect of year end performance is:

                        (i)   24% based on revenue
                        (ii)  36% based on earnings
                              60% in total

            As stated in Appendix II, there is a minimum, target and maximum
            achievement level for payout based on annual performance, for both
            the Revenue and the Earnings component, subject to the following:

                        (i)   No annual bonus payments will be made for either
                              component if the minimum Earnings number is not
                              achieved (for fiscal 2006 this is .57); and

<PAGE>

                        (ii)  Actual payment for performance between minimum,
                              target and maximum achievement will be prorated
                              accordingly.

6.    PAYMENT OF BONUSES

      Funded bonus will be payable not later than sixty days after the end of
      the period in which the bonus was earned provided that the results for the
      period have been issued to the public.

7.    TERMINATION OF EMPLOYMENT

      If a Participant's employment by the Company is terminated, the
      participant's entitlement to payment under this Plan shall be as
      determined under the terms of the Company's Severance Pay Plan, as amended
      to and in effect as of the date of termination.

8.    BENEFICIARY DESIGNATIONS

      8.1   If a Participant's employment with the Company is terminated by his
            death or if he dies after termination of his employment but prior to
            the distribution to him of all amounts payable to him under the
            Plan, any amounts otherwise payable to him hereunder shall be
            distributed to his designated beneficiary or beneficiaries. For the
            purposes of this plan a Participant's beneficiary will be the
            beneficiary designated under Company provided life insurance
            coverage. However, a Participant may from time to time revoke or
            change any beneficiary designation on file with the Company.

            If there is no effective beneficiary designation on file with the
            Company at the time of a Participant's death, distribution of
            amounts otherwise payable to the deceased Participant under this
            Plan shall be made to the Participant's estate. If a beneficiary
            designated by the Participant to receive his benefits shall survive
            the Participant but die before receiving all distributions
            hereunder, the balance thereof shall be paid to such deceased
            beneficiary's estate, unless the deceased beneficiary designation
            provides otherwise.

      8.2   The Company shall deduct from the distributions to be made to a
            Participant or his designated beneficiary or beneficiaries under
            this Plan any federal, state or local withholding or other taxes or
            charges which the Company is from time to time required to deduct
            under applicable law and all amounts distributable under this Plan
            are stated herein before any such deductions. The Company may rely
            on a written opinion from its legal counsel regarding any questions
            which may arise in connection with any such deductions.

9.    RIGHTS, PRIVILEGES AND DUTIES OF PARTICIPATION

      9.1   No participant or other person shall have any interest in any fund
            or in any specific asset or assets of the Company and its
            Subsidiaries by reason of being a Participant under this Plan nor
            any right to receive any distributions under the Plan except as and
            to the extent expressly provided in the Plan.

      9.2   The Company shall have the right, but shall be under no obligation,
            to segregate cash to fund bonuses payable under the Plan. However,
            any such segregated amounts shall at all times remain Company
            assets, subject to the claims of its creditors.

      9.3   Each Participant shall be entitled to receive a current copy of the
            Plan upon his designation as a Participant if a written request for
            a copy of the Plan is provided to the Chief Executive Officer or the
            Chairman of the Board. Thereafter, as long as he remains a
            Participant, he shall be entitled to receive copies of any
            amendments to the Plan within sixty (60) days after their adoption.

<PAGE>

      9.4   The designation of any employee as a Participant under this Plan
            shall not be construed as conferring upon such employee any right to
            remain in the employ of the Company and each such Participant shall
            remain an employee at will. The right of the Company to discipline
            or discharge an employee shall not be affected in any manner by
            reason of such employee's designation as a Participant under this
            Plan.

      9.5   To the extent permitted by law, the right of any Participant or any
            beneficiary to receive any payment hereunder shall not be subject to
            alienation, transfer, sale, assignment, pledge, attachment,
            garnishment or encumbrance of any kind. Any attempt to alienate,
            transfer, sell, assign, pledge or otherwise encumber any such
            payment whether presently or thereafter payable, shall be void. Any
            payment due hereunder shall not in any manner be subject to any
            debts or liabilities of any Participant or his beneficiary.
