Section 7. Payment in the Event of Death. In the event that an Eligible Nonemployee Director dies prior to the receipt of all retirement benefits set forth in the Plan, the Company shall pay the present value of the remaining unpaid retirement benefits owing to the Eligible 3 Nonemployee Director under the Plan in one cash lump sum within sixty (60) calendar days following the date of death. The interest rate to be used to determine the present value of the unpaid retirement benefits shall be the six-month U.S. Treasury Bill rate in effect on the date of death. Such payment shall he made to the surviving spouse of the Eligible Nonemployee Director, if any. If there is no surviving spouse, then the payment shall be made to the representative of the estate of the Eligible Nonemployee Director. Section 8.

For purposes of this Section 8, the interest rate to be used to determine the present value of the unpaid retirement benefits shall be the six-month U.S. Treasury Bill rate in effect on 4 the date of termination of Service. Payments of retirement benefits under this Section 8 shall be made within sixty (60) calendar days following the date of termination of Service on the Board. In the event that the Committee determines that any payment, whether paid or payable or distributed or distributable pursuant to the Plan would be subject to the excise tax imposed by Section 4999 of the Internal Revenue Code of 1986, as amended, or any interest or penalty with respect to such excise tax (such excise tax together with any interest or penalties thereon are hereinafter referred to collectively as the "Excise Tax"), the Nonemployee Director subject to the Excise Tax shall be paid an additional payment (a "Gross-Up Payment") in an amount such that, after the payment by such Nonemployee Director of all taxes (together with any interest or penalties imposed with respect to such taxes), including any Excise Tax imposed upon the Gross-Up Payment, such Nonemployee Director retains an amount of the Gross-Up Payment equal to the Excise Tax imposed upon the payment of retirement benefits under the Plan. Section 9. Unfunded Plan. The Plan shall be a noncontributory, nonqualified and unfunded plan. Retirement benefit payments under the Plan shall represent an unsecured, general obligation of the Company, and shall be paid by the Company from its general operating assets. No special fund or trust shall be required to be created by the Company to fund the obligations under the Plan, nor shall any notes or securities be issued with respect to any retirement benefits under the Plan. Section 10. Certain Payments. Whenever a former Nonemployee Director who is entitled to receive a payment under the Plan is a person under legal disability or a person not adjudicated incompetent but who, by reason of illness or mental or physical disability, is, in the opinion of the Committee, unable to manage properly his or her affairs, then such payments shall 5 be paid in one of the following ways, as the Committee deems advisable: (i) to such person directly; (ii) to the legally appointed guardian or conservator of such person for his or her exclusive benefit; or (iii) in such other manner for the exclusive benefit of such person as the Committee considers advisable. Any payment made in accordance with the provisions of this Section 10 shall be a complete discharge of any liability of the Company for the making of such payment under the Plan. Section 11. Miscellaneous. (a) Neither the establishment of the Plan, nor any action taken thereunder, shall in any way obligate: (i) the Company to nominate a Nonemployee Director for reelection or to continue to retain a Nonemployee Director or (ii) a Nonemployee Director to agree to be nominated for reelection or to continue to serve on the Board. (b) Subject to the provisions of Section 3 hereof, the Plan may not be canceled by the Company upon any merger or consolidation with, or acquisition of the Company by, any other entity, but shall be binding upon and inure to the benefit of the successors and assigns of the Company, and the heirs, executors, administrators, and assigns of each Eligible Nonemployee Director. (c) The Plan shall not affect in any way the rights of any Eligible Nonemployee Director under any deferred compensation plan or agreement between such Director and the Company. (d) The Plan shall be governed by and construed according to the laws of the state of Indiana.
