_______________________________________________________________________________________________________________________

       (c)     A MIP Objective Sheet will be prepared for each Participant annually. This schedule will detail the Plan objectives that the participant will be measured against, including the relative weighting and planned value of each objective. This schedule will be submitted to the Committee or its Agent.

5.     Unfunded Arrangement. The plan shall be unfunded. The Company shall not be required to establish any special or separate fund or to make any other segregation of assets to assure any payment under the Plan, and such payments shall be pari passu with the claims of the Company's general creditors.

6.     Formula for Calculation of Awards. Subject to adjustment under Section 7, as of the end of the Award Period, the actual award for a Participant shall be calculated by multiplying the Participant's Annual Base Salary by the percentage of each factor (or portion thereof, if applicable) achieved in the schedule prepared for such Participant, as determined by reference to the actual results achieved or other method set forth for determination of accomplishment compared to the objectives set forth on the Participant's MIP Objective Sheet at the commencement of the Plan Year. The resulting amounts shall then be added to obtain the actual award payable to the Participant. A Participant may be entitled to receive up to 125% of the indicated award for a particular factor in the event that actual results for that factor are in excess of the objectives set forth in the Plan. This treatment will be indicated at the beginning of the plan year, set forth on the individual's MIP Objective Sheet and will be approved by the Committee. The cumulative award for each factor may be limited to a maximum payment per participant of fifty percent (50%) of the maximum award (inclusive of awards for over-plan achievement) if the Corporate, Group or Business Unit Operating Profit fails to meet the minimum level of Earnings per Share or Operating Profit designated by the Committee.

7.     Discretionary Awards. The amount of awards calculated pursuant to Section 6 above may be recommended for adjustment by the CEO or the Chairman of the Company to reflect any inequities in the evaluation of achievement of management objectives or to reflect any other inequities that arise from the application of the formula calculations. Such adjustment may be made with respect to the calculation of awards for one or more Participants. All such discretionary awards and related adjustments must be submitted to and approved by the Committee.

8.     Normal Payment of Awards. Subject to Section 9, payment of awards earned during any Award Period shall be made in a single cash payment on the Award Date.

9.     Effect of Termination of Employment.

       (a)     Any participant whose active employment terminates before the end of an Award Period, or prior to an Award Date, for any reason other than death, Normal Retirement, Early Retirement, Disability or transfer to a position not deemed by the Committee appropriate to include the employee as a Participant under the Plan, shall forfeit all right to any award for that Award Period; provided, however, that notwithstanding the foregoing, the Committee may authorize the payment to such Participant of such portion of the award as it deems appropriate based upon such Participant's performance and the Company, Group or Business Unit performance during that portion of the Award Period for which such Participant was actively employed and eligible.

       (b)     If a Participant's active employment terminates during an Award Period as a result of death, Normal Retirement, Early Retirement or Disability the provisions of Section 3(b) shall be applied, with the phrase "Exit" being read to mean death, Normal Retirement, Early Retirement or Disability, as the case may be.
