SECTION 4 AWARD GRANTS AND PAYOUT DETERMINATION ------------------------------------- 4.1 Award Grants. The Committee in its sole discretion may grant Awards to eligible Participants on an annual basis. It is intended that Performance Periods will overlap. However, Awards do not necessarily have to be granted on an annual basis. Awards will be earned by Participants during the Performance Period if and to the extent the Performance Goals are met. 4.2 Establishment of Performance Goals, Weightings, and Performance Payout Formulas. In advance of each Performance Period, the Committee shall establish the appropriate Performance Goals, Weightings, and Performance Payout Formulas for purposes of the Plan. Performance Goals, Weightings, and Performance Payout Formulas may vary by Participant in the Plan and Performance Period. The degree to which Awards are earned by achievement of one Performance Goal shall have no direct effect on the determination of Awards earned by achievement of other Performance Goals. To establish the Performance Goals, Weightings, and Performance Payout Formulas for each Performance Period, the Committee will use any information it considers relevant regarding the likely performance of the Company. The Performance Goals, Weightings, and Performance Payout Formulas will be communicated to Participants as soon as practicable following their determination by the Committee. If during a Performance Period the Committee determines a change in the Company's business, operations, corporate or capital structure, the manner in which it conducts business or any other change to be extraordinary and material and determines that, as a result of such change, the established Performance Goals, Weightings, and Performance Payout Formulas are no longer appropriate, the Committee may make modifications as it deems appropriate and equitable in the Committee's sole and absolute discretion. 4.3 Assignment of Target Incentive Awards. For each Performance Period, the Committee shall determine and assign the Target Incentive Award for each Participant. Such determination shall be based on the assessed impact the Participant's position exerts on overall Company results. 4.4 Determination of Payouts. Payouts may vary above and below the Target Incentive Awards as determined in Section 4.2 preceding, dependent upon the achievement of the established Performance Goals, in accordance with the Weightings and Performance Payout Formulas prescribed by the Committee. The Payouts on behalf of a non-officer or a Participant below the level of Senior Vice President must be approved by the Committee. Payment of the Payout on behalf of the Chief Executive Officer and any other Participant who is a Senior Officer of the Company will be approved by the Board. The Committee's determination of the Payouts shall be final, binding, and conclusive. 4.5 Limitation on Amounts Available for Payouts. The aggregate amount available each Plan Year for Payouts shall be limited to 3% of annual net income of the Company. The Committee may, at its discretion, set any limit on the aggregate dollar amount available for Payouts during any Performance Period. To the extent Payouts need to be limited in a Performance Period, Awards will be reduced on a prorated basis. SECTION 5 PAYOUT ------ 5.1 Payout. A Participant's Payout shall be paid to the Plan Agent on behalf the Participant no later than 90 days after publication of the Company's audited financial statements reflecting the last fiscal year of the Performance Period (the "Payout Date") and, subject to Sections 5.3 and 5.5, shall be applied by the Plan Agent to the purchase of Stock in accordance with Section 7.3. 5.2 Payment on Death, Layoff, Disability, and Retirement. Prorated payments that are made pursuant to Section 3.2 shall be paid to the Plan Agent on behalf of the Participant, or in the event of death, on behalf of the Participant's Beneficiary, as soon as practicable after termination of employment. The payments to be prorated shall be restricted to those payable for the performance cycle ending with the calendar year in which the employee terminates employment. Prorated payments, subject to Section 5.5, shall be applied by the Plan Agent to the purchase of Stock in accordance with Section 7.3. 5.3 Deferral of Payouts. Notwithstanding any provisions of the Plan to the contrary, Payouts may be deferred at the election of the Participant in accordance with the applicable provisions of the Company's Deferred Compensation Plan. In the event of such election, all aspects of Payouts shall be governed by the applicable provisions of the Company's Deferred Compensation Plan. 5.4 Payment Upon Change in Control. In the event of a Change in Control of the Company, each Award theretofore granted will be paid by the Company in cash directly to the Participants in a prorated amount based on performance to date as designated by the Committee in its sole and absolute discretion. Payments shall be made within 60 days of the Change in Control of the Company. 5.5 Maximum Number of Shares: Stockholder Approval. The aggregate number of shares of Stock purchased by the Plan Agent on behalf of Participants who are officers (within the meaning of Section 16(b) of the Securities Exchange Act of 1934, as amended) ("Officers") shall not exceed 1,500,000. In the event that prior to the first Payout Date under the Plan the Plan has not been approved by the stockholders of the Company, or the Plan Agent has purchased the maximum number of shares of Stock available under the Plan, all Payouts for Participants who are Officers shall be paid in the form of cash paid directly to the Participant or Participant's Beneficiary. SECTION 6 DESIGNATION OF BENEFICIARIES ---------------------------- A Participant may designate a Beneficiary or Beneficiaries who in the event of the Participant's death are to receive the Stock that otherwise would have been delivered to the Participant. All designations shall be in writing and shall be effective only if and when delivered to the Committee during the lifetime of the Participant. A Participant may, from time to time during his lifetime, change his Beneficiary or Beneficiaries by a written instrument delivered to the Committee. If a Participant designates a Beneficiary without providing in the designation that the Beneficiary must be living at the time of each Payout, the designation shall vest in the Beneficiary all of the Payouts whether payable before or after the Beneficiary's death, and any Payouts remaining upon the Beneficiary's death shall be made to the Beneficiary's estate. In the event a Participant shall not designate a Beneficiary or Beneficiaries as aforesaid, or if for any reason such designation shall be ineffective, in whole or in part, the Stock that otherwise would have been delivered to such Participant shall be paid to the Participant's beneficiary as designated by the Participant in the Company's group life insurance program. In the event the Participant's beneficiary as designated in the Company's group life insurance program is ineffective, in whole or in part, the Stock shall be delivered to the Participant's estate and in such event the term "Beneficiary" shall include his estate.

The Plan Agent shall submit all shares purchased pursuant to the Plan to a transfer agent (the "Transfer Agent") for the Stock, and arrange to have new certificates issued in the names of the Participants entitled thereto.
