ARTICLE II

ELIGIBILITY

A Participant who is eligible to receive a Qualified Plan Retirement Benefit, the amount of which is reduced by reason of the application of the limitations on benefits imposed by any provisions of the Code, as in effect on the date of the Participant’s Separation From Service, to the Qualified Plan shall be eligible to receive a Restoration Retirement Benefit. The Surviving Spouse of a Participant described in the preceding sentence who dies prior to commencement of payment of his Qualified Plan Retirement Benefit shall be eligible to receive a Restoration Surviving Spouse Benefit.

ARTICLE III

RESTORATION RETIREMENT BENEFIT

3.1 Amount. The Restoration Retirement Benefit payable to an eligible Participant shall be a monthly amount equal to the difference between (a) and (b) below, determined in the form of a straight life annuity over the lifetime of the Participant only, commencing on his Normal Retirement Date:

(a) the monthly amount of the Qualified Plan Retirement Benefit to which the Participant would have been entitled under the Qualified Plan if such Benefit were computed without giving effect to any limitations on benefits imposed by any provisions of the Code;

LESS

(b) the monthly amount of the Qualified Plan Retirement Benefit actually payable to the Participant under the Qualified Plan.

2

The amounts described in (a) and (b) shall be computed as of the date of Separation from Service of the Participant with the Company and all affiliates.

3.2 Form of Benefit. The Restoration Retirement Benefit payable to a Participant shall be specified by the Participant by notice given to the Company no later than thirty (30) days after the first day of the Participant’s taxable year immediately following the first year the Participant accrues a benefit under this Plan. Such election shall specify either a lump sum or a method of distribution from among the methods of distribution then available under the Qualified Plan. If no such election is made by the Participant on or before the date specified in the immediately preceding sentence, the form of benefit shall be a single life annuity payable over the Participant’s lifetime, or if married at the time benefits commence, shall be an actuarially equivalent 50% joint and survivor annuity, with the survivor annuity payable to the Participant’s spouse over the spouse’s lifetime if the Participant predeceases the spouse.

3.3 Commencement of Benefit. Unless Section 3.4 is applicable, payment of the Restoration Retirement Benefit to a Participant shall commence on the first day of the month coincident with or next following the later of the Participant’s Separation From Service with the Company or age 50. The same early commencement or late commencement factors as specified in the Qualified Plan shall be used in computing the benefit under this Plan.

3.4 Payments to a Key Employee. Notwithstanding anything elsewhere contained in the Plan, a payment shall not be paid to a Participant who is a Key Employee (as defined in Section 416(i)) of the Internal Revenue Code of 1986, as amended without regard to paragraph (5) thereof), if on the date of his Separation From Service the capital stock of the Company is publicly traded on an established securities market or otherwise, earlier than the date six months after the date of his Separation From Service with the Company (or if earlier, the date of his death). On such date any payment which was delayed due to a Participant being a “Key Employee” shall be immediately paid to the Participant along with accrued interest at the prime rate in effect on the date of the Participant’s Separation From Service as reported in The Wall Street Journal (or if no longer reported by said newspaper, then as reported in such other nationally recognized publication as selected by the Company for the period of such delay). If a person is a Key Employee at any time during the 12-month period ending on December 31 of the calendar year before his Separation From Service, he will be treated as a Key Employee for the 12-month period beginning on the following April 1.

3.5 Actuarial Equivalent. A Restoration Retirement Benefit which is payable in any form other than a straight life annuity over the lifetime of the Participant, shall be the actuarial equivalent of the Restoration Retirement Benefit set forth in Section 3.1 above as determined by the same actuarial adjustments as those specified in the Qualified Plan with respect to determination of the amount of the Qualified Plan Retirement Benefit on the date for commencement of payment hereunder. The same early commencement or late commencement factors as specified in the Qualified Plan shall be used in computing the benefit under this Plan.

ARTICLE IV

RESTORATION SURVIVING SPOUSE BENEFIT

4.1 Amount. If a Participant dies prior to commencement of payment of his Qualified Plan Retirement Benefit under circumstances in which a Qualified Plan Surviving Spouse Benefit is payable to his Surviving Spouse, then a Restoration Surviving Spouse Benefit is

3

payable to his Surviving Spouse as hereinafter provided. The monthly amount of the Restoration Surviving Spouse Benefit payable to a Surviving Spouse shall be calculated on the first day of the month coincident or following the later of the date of death of the Participant or the 50^th anniversary of the Participant’s birth and shall be equal to the difference between (a) and (b) below as of the specified calculation date:

(a) the monthly amount of the Qualified Plan Survivor Spouse Benefit to which the Surviving Spouse would have been entitled under the Qualified Plan if such Benefit were computed without giving effect to any limitations on benefits imposed by the Code;

LESS

(b) the monthly amount of the Qualified Plan Surviving Spouse Benefit actually payable to the Surviving Spouse under the Qualified Plan.

4.2 Form and Commencement of Benefit. A Restoration Surviving Spouse Benefit shall be the actuarial equivalent of the amount calculated pursuant to Sections 4.1 and 3.5 and shall be paid in a lump sum to the Surviving Spouse on the first day of the month following the later of the date of death of the Participant or the 50^th anniversary of the Participant’s birth.

5.3 Claims Procedure. The Claims Procedure is set forth in Exhibit A attached hereto.

ARTICLE VI

AMENDMENT OF TERMINATION

6.1 Amendment or Termination. The Company intends the Plan to be permanent but reserves the right to amend or terminate the Plan when, in the sole opinion of the Company, such amendment or termination is advisable. Any such amendment or termination shall be made pursuant to a resolution of the Board and shall be effective as of the date of such resolution.

6.2 Effect of Amendment or Termination.

ARTICLE VII

GENERAL PROVISIONS

7.1 Funding. The Plan at all times shall be entirely unfunded and no provision shall at any time be made with respect to segregating any assets of the Company for payment of any benefits hereunder. No Participant, Surviving Spouse or any other person shall have any interest in any particular assets of the Company by reason of the right to receive a benefit under the Plan and any such Participant, Surviving Spouse or other person shall have only the rights of a general unsecured creditor of the Company with respect to any rights under the Plan.

7.2 General Conditions. Except as otherwise expressly provided herein, all terms and conditions of the Qualified Plan applicable to a Qualified Plan Retirement Benefit or a Qualified Plan Surviving Spouse Benefit shall also be applicable to a Restoration Retirement Benefit or a Restoration Surviving Spouse Benefit payable hereunder. Any Qualified Plan Retirement Benefit or Qualified Plan Surviving Spouse Benefit, or any other benefit payable under the Qualified Plan, shall be paid solely in accordance with the terms and conditions of the Qualified Plan and nothing in this Plan shall operate or be construed in any way to modify, amend or affect the terms and provisions of the Qualified Plan.

7.3 No Guaranty of Benefits. Nothing contained in the Plan shall constitute a guaranty by the Company or any other entity or person that the assets of the Company will be sufficient to pay any benefit hereunder.

7.4 No Enlargement of Employee Rights. No Participant or Surviving Spouse shall have any right to a benefit under the Plan except in accordance with the terms of the Plan. Establishment of the Plan shall not be construed to give any Participant the right to be retained in the service of the Company.

7.5 Spendthrift Provision. No interest of any person or entity in, or right to receive a benefit under, the Plan shall be subject in any manner to sale, transfer, assignment, pledge, attachment, garnishment, or other alienation or encumbrance of any kind; nor may such interest or right to receive a benefit be taken, either voluntarily or involuntarily, for the satisfaction of the debts of, or other obligations or claims against, such person or entity, including claims for alimony, support, separate maintenance and claims in bankruptcy proceedings.

7.6 Applicable Law. The Plan shall be construed and administered under the laws of the State of Kansas.

7.7 Small Benefits. If the actuarial value of any Restoration Retirement Benefit or Restoration Surviving Spouse Benefit is less than $5,000, the Company may pay the actuarial value of such Benefit to the Participant or Surviving Spouse in a single lump sum in lieu of any further benefit payments hereunder.

7.8 Incapacity of Recipient. If any person entitled to a benefit payment under the Plan is deemed by the Company to be incapable of personally receiving and giving a valid receipt for such payment, then, unless and until claim therefor shall have been made by a duly appointed guardian or other legal representative of such person, the Company may provide for such payment or any part thereof to be made to any other person or institution then

5

contributing toward or providing for the care and maintenance of such person. Any such payment shall be a payment for the account of such person and a complete discharge of any liability of the Company and the Plan therefor.

7.9 Corporate Successors. The Plan shall not be automatically terminated by a transfer or sale of assets of the Company or by the merger or consolidation of the Company into or with any other corporation or other entity, but the Plan shall be continued after such sale, merger or consolidation only if and to the extent that the transferee, purchaser or successor entity agrees to continue the Plan. In the event that the Plan is not continued by the transferee, purchaser or successor entity, then the Plan shall terminate subject to the provisions of Section 6.2.

7.10 Unclaimed Benefit. Each Participant shall keep the Company informed of his current address and the current address of his spouse. The Company shall not be obligated to search for the whereabouts of any person. If the location of a Participant is not made known to the Company within three (3) years after the date on which payment of the Participant’s Restoration Retirement Benefit may first be made, payment may be made as though the Participant had died at the end of the three-year period. If, within one additional year after such three-year period has elapsed, or, within three years after the actual death of a Participant, the Company is unable to locate any Surviving Spouse of the Participant, then the Company shall have no further obligation to pay any benefit hereunder to such Participant or Surviving Spouse or any other person and such benefit shall be irrevocably forfeited.

7.11 Limitations on Liability. Notwithstanding any of the preceding provisions of the Plan, neither the Company nor any individual acting as an employee or agent of the Company shall be liable to any Participant, former Participant, Surviving Spouse or any other person for any claim, loss, liability or expense incurred in connection with the Plan.

7.12 Department of Labor Notice. The Company shall be responsible for filing with the Department of Labor a notice in the form attached hereto as Exhibit B, not later than 120 days after the adoption of this Plan.

7.13 Internal Revenue Code Section 409A. This Plan is intended to meet the requirements of Section 409A of the Code and all terms and provisions shall be construed in accordance with such intent. Any provision of this Plan that would cause the payment, settlement or deferral thereof to fail to satisfy Section 409A of the code may be amended by the Company, to the extent permissible, to comply with Section 409A of the Code, in accordance with regulations and other guidance issued under Section 409A of the Code.

IN WITNESS WHEREOF, the Company has caused this Plan to be executed by a duly authorized officer this 2^nd day of April, 2010.
