The Board shall have the full power to amend or terminate the Plan at any time prior to the occurrence of a Change in Control, as further described in Article VII herein. V. ELIGIBILITY AND PARTICIPATION SECTION 5.1. PARTICIPATION. Upon approval by the Board, Designated Officers shall automatically become Participants under the Plan. Retired individuals who have a vested accrued benefit under the Plan will also be considered to be Participants. SECTION 5.2. NO EMPLOYMENT GUARANTEE.

INDIVIDUAL ACCOUNTS AND THE RABBI TRUST SECTION 7.1. ESTABLISHMENT OF A RABBI TRUST. After the Effective Date, the Company shall be authorized, but shall not be required, to establish a revocable Rabbi Trust for the benefit of the Participants, both active and retired. Any such Rabbi Trust shall have an independent trustee, selected by the Company, and, it shall contain restrictions on the Company's ability to amend or terminate any of the terms thereof after the Rabbi Trust shall become irrevocable as provided in Section 7.2. All assets held in the Rabbi Trust (while revocable or irrevocable) shall at all times be specifically subject to the claims of the Company's general creditors in the event of bankruptcy or insolvency; such terms shall be specifically defined within the provisions of the Rabbi Trust, along with a required procedure for notifying the Trustee of any such bankruptcy or insolvency. 8 SECTION 7.2. CAUSING THE TRUST TO BECOME IRREVOCABLE. The instrument establishing any such Rabbi Trust shall provide that the Rabbi Trust shall be revocable until the occurrence of either of the following: (i) A Change in Control; or (ii) A majority vote by the Incumbent Board to make the Rabbi Trust irrevocable. SECTION 7.3. PAYMENT OF BENEFITS FROM THE TRUST. The Company shall be primarily obligated to pay all benefits of Participants under the Plan, whether the Rabbi Trust is revocable or irrevocable at the time. In the event the Company fails to fulfill any such obligation hereunder in a timely manner, the Trustee shall be empowered, under the terms of the Rabbi Trust, to either cash in any related life insurance policies or to borrow against the policies, to the extent necessary to pay past due benefits directly from the Trust. VIII. BENEFICIARY DESIGNATION SECTION 8.1. DESIGNATION OF BENEFICIARY. Each Participant shall be entitled to designate one or more beneficiaries by filing a signed, written notice of such designation with the Committee, in a form as the Committee may prescribe. A Participant may revoke or modify a beneficiary designation at any time by filing a new beneficiary designation form with the Committee. SECTION 8.2. PAYMENT TO A PARTICIPANT'S ESTATE. A Participant's beneficiary designation shall be deemed automatically revoked in the event all designated beneficiaries predecease such Participant or, if the sole beneficiary is such Participant's Spouse, in the event of dissolution of marriage. In such event, or in the event a Participant does not designate a beneficiary, the benefits under Sections 6.5(a) and 6.5(d) shall be paid to such Participant's estate. IX. MISCELLANEOUS SECTION 9.1. UNFUNDED PLAN. This Plan is intended to be an unfunded plan maintained primarily to provide benefits to a "select group of management or highly compensated employees" within the meaning of Sections 201, 301, and 401 of ERISA and, therefore, is further intended to be exempt from the provisions of Parts 2, 3, and 4 of Title I of ERISA. Accordingly, the Committee may terminate the Plan for any or all Participants in order to achieve and maintain this intended result, provided that previously accrued benefits hereunder shall not be reduced or otherwise adversely affected without the written consent of all affected Participants. SECTION 9.2. WITHHOLDING. The Company shall have the right to require Participants to remit to the Company an amount sufficient to satisfy Federal, state, and local tax withholding requirements, or to deduct from any or all payments made pursuant to the Plan amounts 9 sufficient to satisfy such tax withholding requirements. In the event any FICA, FUTA, Social Security, Medicare or any similar taxes become due on benefits (or the value of such benefits) accrued under this Plan at any time prior to the actual payment of benefits under this Plan, the Company shall be authorized to withhold from the regular salary of such Participant the amount of any such tax payable by the Participant. Withholding shall take place during the same calendar year in which the taxes on such benefits become due, or at such time as may be required by Internal Revenue Service regulations. SECTION 9.3. COSTS OF THE PLAN. All costs of implementing and administering the Plan shall be borne by the Company. SECTION 9.4. NONTRANSFERABILITY. Neither the Participants nor any designated beneficiary shall have the right to sell, assign, transfer, or otherwise convey the right to receive any payment hereunder; nor shall any such payment be subject to attachment, garnishment, levy, pledge, bankruptcy, or any other manner or kind of execution in connection with any claim against the Participants or any designated beneficiary thereof. SECTION 9.5. SUCCESSORS. All obligations of the Company under the Plan shall be binding upon and inure to the benefit of any successor to the Company, whether the existence of such successor is the direct or indirect result of a merger, consolidation, or reorganization involving the Company or the purchase or other acquisition of all or substantially all of the business and/or assets of the Company. SECTION 9.6. ADDRESS OF PARTICIPANT OR BENEFICIARY. Each Participant shall keep the Company apprised of his or her current address and that of any designated beneficiary during his or her participation in the Plan. Upon the death of a Participant, any beneficiaries entitled to receive benefit payment under the Plan shall keep the Company apprised of their current address until the entire amount to be distributed has been paid. SECTION 9.7. APPLICABLE LAW. To the extent not preempted by Federal law, the Plan shall be governed by and construed in accordance with the laws of the state of Iowa. 10
