ARTICLE II

Eligibility and Participation

Participation in the Plan is limited to those individuals who have been designated as Participants by the Committee.  An individual will become covered by the Plan effective as of the date specified by the Committee.

ARTICLE III

Awards

3.1          Annual Determination of Awards.  Annually, the Committee will notify a Participant of the terms and conditions of an Award.  In making these determinations, the Committee may consider factors such as the nature of the services rendered by the Participant, his or her current and potential contributions to the Company’s success, the Participant’s Base Salary, and such other factors it considers relevant.

3

3.2          Communication of Awards.  The Committee will deliver a Notice of Award to each Participant receiving an Award for a calendar year within 30 days of the date the Committee approves the Award.

3.3          Components of Calculation.  The Committee, in its sole discretion, will establish the following business criteria for Awards:

(a)                                  The performance measures which comprise the WAP; and

(b)                                 The relative weight accorded each performance measure.

3.4                               Earning of Awards.  An Award will be treated as earned (a) provided the Participant is employed on the last day of the calendar year, and (b) to the extent the WAP for such calendar year equals or exceeds the following percentages:

*For WAP levels between the 25th and 75th percentiles, the payout percentage will be interpolated.  If a Participant incurs a Termination of Service for any reason prior to the time an Award has been earned, he or she will not earn any portion of an Award.

3.5          Time and Form of Payment of Earned Awards.  Except as set forth below, earned Awards will be paid in two installments provided the Participant is employed on the date of payment.  The first installment will be an amount equal to two-thirds of the earned Award and will be paid in cash within 30 days after the Committee calculates the WAP in the April following the end of the calendar year.  The second installment will be an amount equal to one-third of the earned Award and will be paid in cash on the first anniversary of the initial payment.  Notwithstanding the foregoing, if a Participant’s employment is terminated due to death, Disability or Retirement, after an Award has been earned but before it has been paid, the Participant, or his or her estate, will receive a lump sum payment of the earned Award within 45 days of the date of his death, Disability or Retirement.

3.6          Clawback of Awards.  In the event the Company is required to prepare an accounting restatement due to the Company’s material noncompliance with any financial reporting requirement under securities laws, and the amount paid to a Participant under an earned Award was calculated using the erroneous data, and the accounting restatement occurred within three years from the date of payment of the improperly calculated earned Award, then the Participant shall be required to repay the Company the excess amount which should not have been paid to the Participant under the accounting restatement.

4

3.7          Withholding of Taxes.  Each Participant will be solely responsible for, and the Company will withhold from any amounts payable under the Plan, all applicable federal, state, city and local income taxes and the Participant’s share of applicable employment taxes.

ARTICLE IV

Miscellaneous

4.1          Amendment or Termination.  The Committee may, at any time, alter, amend, modify, suspend or terminate the Plan, but may not, without the consent of a Participant to whom an Award has been made, make any alteration which would adversely affect an Award previously granted under the Plan except as provided in Section 3.6.  The Committee may also amend the Plan without a Participant’s consent if it is determined to be necessary to comply with applicable law or to preserve the intended tax or accounting treatment of the Plan.

4.2          Employment Rights.  The Plan does not constitute a contract of employment, and participation in the Plan will not give a Participant the right to be rehired or retained in the employ of the Company or any Subsidiary, nor will participation in the Plan give any Participant any right or claim to any benefit under the Plan, unless such right or claim exists under the terms of the Plan.

4.3          Evidence.  Evidence required of anyone under the Plan may be by certificate, affidavit, document or other information which the person relying thereon considers pertinent and reliable, and signed, made or presented by the proper party or parties.

4.4          Gender and Number.  Where the context permits, words in the masculine gender will include the feminine gender, the plural will include the singular and the singular will include the plural.

4.5          Action by the Board or Committee.  Any action required of or permitted by the Board or Committee under this Plan will be by resolution of the Board, the Committee or by a person or persons authorized by resolution of the Board or Committee.

4.6          Controlling Laws.  Except to the extent superseded by laws of the United States, the laws of Indiana will be controlling in all matters relating to the Plan.  The Plan and all Awards are intended to comply with the applicable provision of Code Section 409A and will be construed by the Board or Committee, as the case may be, in a manner which complies with the applicable provisions of Code Section 409A.  To the extent there is any conflict between a provision of the Plan or a Notice of Award and a provision of Code Section 409A, the applicable provision of Code Section 409A will control.

4.7          Mistake of Fact.  Any mistake of fact or misstatement of fact will be corrected when it becomes known and proper adjustment made by reason thereof.

4.8          Severability.  In the event any provision of the Plan is held to be illegal or invalid for any reason, such illegality or invalidity will not affect the remaining parts of the Plan, and the Plan will be construed and endorsed as if such illegal or invalid provision had never been contained in the Plan.

5

4.9          Effect of Headings.  The descriptive headings of the Articles and Sections of the Plan are inserted for convenience of reference and identification only and do not constitute a part of the Plan for purposes of interpretation.

4.10        Nontransferability.  No Award or Award payment will be transferable, except by the Participant’s will or the applicable laws of descent and distribution.  During the Participant’s lifetime, his Award will be payable only to the Participant or his guardian or attorney-in-fact.  The payment and any rights and privileges pertaining thereto may not be transferred, assigned, pledged or hypothecated by him in any way, whether by operation of law or otherwise and will not be subject to execution, attachment or similar process.

4.11        No Liability.  No member of the Board or the Committee or any officer or Participant of the Company or Subsidiary will be personally liable for any action, omission or determination made in good faith in connection with the Plan.  The Company will indemnify and hold harmless the members of the Committee, the Board and the officers and Participants of the Company and its Subsidiaries, and each of them, from and against any and all loss which results from liability to which any of them may be subjected by reason of any act or conduct (except willful misconduct or gross negligence) in their official capacities in connection with the administration of the Plan, including all expenses reasonably incurred in their defense, in case the Company fails to provide such defense.  By participating in the Plan, each Participant agrees to release and hold harmless each of the Company, the Subsidiaries (and their respective directors, officers and employees), the Board and the Committee, from and against any tax or other liability, including without limitation, interest and penalties, incurred by the Participant in connection with his participation in the Plan.

4.12        Funding.  All amounts payable under the Plan will be paid by the Company from its general assets.  The Company is not required to segregate on its books or otherwise establish any funding procedure for any amount to be used for the payment of benefits under the Plan.  The Company may, however, in its sole discretion, set funds aside in investments to meet its anticipated obligations under the Plan.  Any such action or set-aside amount may not be deemed to create a trust of any kind between the Company and any Participant or beneficiary or to constitute the funding of any Plan benefits.  Consequently, any person entitled to a payment under the Plan will have no rights against the assets of the Company greater than the rights of any other unsecured creditor of the Company.
