IV.162(m) AWARDS.

A.Discretion to Make 162(m) Awards.  The Committee shall have the discretion to designate any Award granted to a Covered Employee as "performance-based compensation" pursuant to section 162(m) of the Code (a "162(m) Award").  The Committee has complete discretion concerning whether a particular Award should be qualified as a 162(m) Award, and in any Fiscal Year a Covered Employee may receive both 162(m) Awards and Awards that are not 162(m) Awards.  Each 162(m) Award shall be subject to the additional provisions set forth below.

B.Performance Criteria for 162(m) Awards.  The performance criteria for any 162(m) Award shall consist of objective tests based on one or more of the following: earnings per share; adjusted earnings per share; sales; earnings; cash flow; profitability; customer satisfaction; investor relations; revenues; financial return ratios; market performance; shareholder return and/or value; operating profits (including earnings before income taxes, depreciation and amortization); net profits; earnings per share growth; profit returns and margins; stock price; working capital; business trends; production cost; project milestones; plant and equipment performance; safety performance; environmental performance; gross margin; operating margin; net margin; expense margins; EBIT margin; EBIT growth; EBITDA margin; EBITDA growth; adjusted EBITDA; NOPAT margin; net assets; working capital; asset turnover; working capital turnover; accounts receivable turnover; accounts payable turnover; inventory turnover; inventory days outstanding; accounts receivable days outstanding; accounts payable days outstanding; debt to equity; debt to capital; current ratio; return on equity; return on assets; return on net assets; return on invested capital; return on gross assets; return on tangible assets; cash flow return on investment; cash value added; price to earnings ratio; market to book ratio; market to capital ratio; cost of capital; cost of debt; cost of equity; market risk premium; stock price appreciation; total shareholder return; economic value added; economic profit; sales growth percentage; EPS growth percentage; cash flow growth year over year; return on total capital, or any combination of the foregoing.  Performance criteria may be measured solely on a corporate, subsidiary, business unit or individual basis, or a combination thereof; may be measured in absolute levels or relative to another company or companies, a peer group, an index or indices or Company performance in a previous period; and may be measured annually or over a longer period of time.

C.Establishment of Performance Goals for 162(m) Awards.  The performance goals for each 162(m) Award and the amount payable if those goals are met shall be established in writing for each specified period of performance by the Committee no later than 90 days after the commencement of the period of service to which the performance goals relate and while the outcome of whether or not those goals will be achieved is substantially uncertain. However, in no event will such goals be established after 25% of the period of service to which the goals relate has elapsed.

D.Limitations on 162(m) Awards.  In any Fiscal Year, no Covered Employee may receive aggregate distributions of more than $2,500,000 from 162(m) Awards.

V.DETERMINATION OF MINIMUM PAYMENT AMOUNTS.

Prior to the end of each Fiscal Year, the Committee, after consultation with the Plan Administrator and on behalf of the Board of Directors and the management of each Subsidiary, shall determine the minimum aggregate amount of Payments to be made by the Company and each Subsidiary pursuant to the Awards granted under the Plan for that Fiscal Year, other than Payments to be made pursuant to 162(m) Awards which will be determined only after the end of the fiscal year.

VI.DETERMINATION OF PAYMENTS.

A.Payments shall be based upon the degree to which the actual performance of the Company and/or Subsidiary exceeds, satisfies or fails to satisfy the predetermined performance criteria established by the Company for that Award.  As soon as practicable after the end of each Fiscal Year, the Committee shall determine the Payment to each Participant based on attainment of the performance criteria for the Participant's Awards for such Fiscal Year.  The Chief Executive Officer shall submit to the Committee a proposed Performance Compensation Payment summary for each Subsidiary and the Company which shall include (i) the actual performance of the Subsidiary and the Company during the Fiscal Year compared to the respective performance criteria previously established for the Subsidiary and the Company Participants for such Fiscal Year, and (ii) the resulting proposed Payments; provided, that the Committee may, following such submission, consider the further recommendations of the Chief Executive Officer.  Final determination of the amount of each Participant's Performance Compensation Payment (if any) as well as the total Payments under the Plan for each Fiscal Year shall be the responsibility of the Committee.

B.The recommended Performance Compensation Payment to a Participant may be denied, or adjusted upward or downward by the Committee as in the Committee's discretion is prudent and advisable based upon its assessment of the Participant's performance and the Company's or Subsidiary's performance, as applicable, during the Fiscal Year; provided that under no circumstances may the Committee use discretion to increase the amount payable to a Participant under a 162(m) Award; and provided further that the total of all Performance Compensation Payments for the Fiscal Year other than Payments under 162(m) Awards shall be no less than the minimum determined by the Committee in accordance with Section V.

VII.MANNER OF AND TIME FOR PAYMENTS.

Once the Payments have been approved by the Committee pursuant to Section VI, the Plan Administrator shall take the necessary actions to notify each Participant of the amount of his or her Performance Compensation Payment.  Performance Compensation Payments will be made through payroll not later than 2½ months following the end of each Fiscal Year.  The Company shall withhold from each Payment all taxes required to be withheld by any federal, state or local government and any other applicable deductions authorized by the Participant.

VIII.DESIGNATION OF BENEFICIARY.

Each Participant shall have the right to designate a beneficiary, and to change such beneficiary from time to time, by filing a request in writing with the Plan Administrator.  If a Participant dies after the end of the Fiscal Year but prior to receiving the Payment due for such Fiscal Year, the Payment will be paid to the Participant's designated beneficiary at the time such amount would have been paid to the Participant, subject to Section VII.  In the event the Participant has not designated a beneficiary, or in the event a beneficiary predeceases the Participant, the amount otherwise payable to such beneficiary shall be paid to the person in, or divided equally among the persons in, the first of the following classes of successive preference beneficiaries in which there shall be any person surviving such Participant:

(1) The Participant's spouse;

(2) The Participant's children; or

(3) The Participant's executors or administrators;

provided that any amount payable to a minor may instead be paid to such adult or adults as, in the sole opinion of the Plan Administrator, are primarily responsible for the custody and support of such minor.

IX.ADMINISTRATION OF THE PLAN.

The Committee has the sole responsibility for overall administration and control of the Plan, including the selection of Participants, the amounts of Awards, the selection and approval of performance criteria, the determination of the minimum total Payments under the Plan for each Fiscal Year, the satisfaction of performance criteria, and the final determination of Payments to each Participant.  The Plan Administrator shall be responsible for implementing the actions required under the Plan.

X.VESTING.

A Participant must be in the employ of the Company or a Subsidiary on the date a Performance Compensation Payment of an Award is made pursuant to Section VII in order to be eligible for Payment pursuant to the Award.  Notwithstanding the foregoing, however, in the event that, either before or after the end of the Fiscal Year, a Participant's employment is terminated by reason of the Participant's death or disability, by the Company without cause, or by the Participant due to retirement on or after the age of 60, the Committee shall have the sole discretion as to whether the Participant shall be entitled to any Payment, and if so, the amount of such Payment, and any such amount shall be paid at the time determined pursuant to Section VII.

XI.AMENDMENT OR TERMINATION.

The Committee may amend or terminate the Plan at any time, but no amendment may impair any of the rights or obligations under any Award theretofore granted to a Participant under the Plan without such Participant's consent; provided, however, that notwithstanding the foregoing the Committee may amend the Plan or any Awards in such manner as it deems necessary to comply with the requirements of any applicable law, rule or regulation.

XII.MISCELLANEOUS.

A.All Payments under the Plan shall be made from the general assets of the Company or Subsidiary, as the case may be.  To the extent any person acquires a right to receive a Payment under the Plan, such right shall be no greater than that of an unsecured general creditor of the Company or Subsidiary.

B.Nothing contained in the Plan and no action taken pursuant thereto shall create or be construed to create a trust of any kind, or a fiduciary relationship between the Company or a Subsidiary and any other person.

C.Except as provided in Section XIII, no amount payable under the Plan shall be subject in any manner to anticipation, alienation, sale, transfer, assignment, pledge, encumbrance or charge, either voluntary or involuntary, and any attempt to so alienate, anticipate, sell, transfer, assign, pledge, encumber or charge the same shall be null and void.  No such amount shall be liable for or subject to the debts, contracts, liabilities, engagements, or torts of any person to whom such benefits or funds are or may be payable.

D.Nothing contained in the Plan is intended or shall be construed to confer upon any Participant the right to continue in the employ of the Company or a Subsidiary or to limit the right of a Participant's employer to discharge the Participant at any time, with or without cause.

E.The Plan shall be construed and administered in accordance with the laws of the State of Missouri, without regard to the principles of conflicts of law which might otherwise apply.

XIII.COVENANTS.
