(ii) The Committee shall determine or approve TAVA Target Bonus Percentages for each Participant and the Company's Cost of Capital for the Plan Year. (iii) The Committee shall establish the Target Improvement and the Bonus Interval for each Plan Year, which standards may each be set by the Committee for one or more Plan Years.

As of the end of each Plan Year, the following determinations shall be made: (i) The Committee shall determine the Company's EVA as of the end of the Plan Year and the resulting Actual Improvement. (ii) The Committee shall determine, or approve the determination of, the TAVA Bonus Factor for each Plan Year, consistent with the terms of the Plan. (b) Determination of TAVA Bonus. Each Participant shall be credited with a TAVA Bonus, if any, for a Plan Year according to the following: (1) The Actual Improvement in EVA for a Plan Year shall be determined by subtracting the EVA for the immediately preceding Plan Year from the EVA for the Plan Year; 4 (2) If the Actual Improvement exceeds the Target Improvement, the amount of that excess shall be the "Excess Improvement"; (3) If the Target Improvement exceeds the Actual Improvement, the amount of that excess shall be the "Shortfall"; (4) The TAVA Bonus Factor shall be determined by comparing the Excess Improvement or Shortfall to the Target Improvement and Bonus Interval, according to the following: (i) If the Actual Improvement equals the Target Improvement, the TAVA Bonus Factor shall equal one (1). (ii) If the Actual Improvement exceeds the Target Improvement, the TAVA Bonus Factor shall equal the Excess Improvement divided by the Bonus Interval, plus one (1). (iii) If the Actual Improvement is less than the Target Improvement, the TAVA Bonus Factor shall equal the Shortfall (expressed as a negative number) divided by the Bonus Interval, plus one (1). (5) The TAVA Bonus for each Participant shall equal the Participant's TAVA Target Bonus, multiplied by the TAVA Bonus Factor, with such amount being credited to the Participant's Bonus Reserve Account in accordance with Section 6 of this Plan. SECTION 6. PAYMENT OF BONUS AMOUNT. (a) Bonus Reserve Account Determination. Each Participant shall have a Bonus Reserve Account to which the TAVA Bonus shall be credited. Each Plan Year the Bonus Reserve Account shall be increased by the amount of any positive TAVA Bonus or decreased by the amount of any negative TAVA Bonus. The bonus payable to a Participant as of the end of a Plan Year, if any ("Bonus Amount"), shall be based upon the Participant's Bonus Reserve Account as of the end of each Plan Year. (b) Determination of Bonus Amount. At the end of each Plan Year, after first crediting the Participant's Bonus Reserve Account with the Participant's TAVA Bonus (which may be positive or negative), the Company shall pay each Participant a Bonus Amount equal to the sum of (i) the Participant's TAVA Bonus, if positive (but not exceeding 120% of the TAVA Target Bonus), plus (ii) one-third of the Participant's remaining Bonus Reserve Account balance as of the end of that Plan Year (after reducing for (i)); provided that the Bonus Amount may not exceed the Participant's Bonus Reserve Account. If the amount in a Participant's Bonus Reserve Account prior to determining the Bonus Amount is less than the Participant's TAVA Bonus, the entire amount of the Participant's Bonus Reserve Account shall be paid. No Bonus Amount shall be payable to a Participant unless and until the Participant has a positive balance in his or her Bonus Reserve Account as of the end of the Plan Year. The Bonus Amount shall be paid by the Company within thirty (30) days following the Committee's determination of the TAVA Bonus Factor. The Bonus Amount determined under this subsection shall not be earned by the Participant until such time as the date on which it is paid. 5 (c) Allocation of TAVA Bonus Factor. A Participant's TAVA Bonus may be based upon the TAVA Bonus Factor for the Company only, or at the discretion of the Committee, a Participant's TAVA Bonus may be based upon the TAVA Bonus Factor for a particular division, operation, or Subsidiary of the Company, or combination thereof as determined by the Committee. (d) Payment Upon Death, Retirement, Disability or Termination by the Company Other Than for Cause. In the event of a Participant's termination of employment due to death, Retirement, Disability or by the Company other than for Cause, the Participant's Bonus Reserve Account shall be credited as of the end of the Plan Year in which termination occurs (the "Termination Year"), with a TAVA Bonus determined in accordance with Section 5 of the Plan, multiplied by a fraction (the "Completion Multiple"), the numerator of which shall equal the total number of days during the Termination Year in which the Participant was employed by the Company, and the denominator of which shall be 365. Thereafter, following the payment, if any, of the Bonus Amount for the Termination Year, the full amount of the Participant's Bonus Reserve Account (if a positive balance then exists) shall be considered earned as of the termination date and shall be paid by the Company to the former Participant, or in the event of his or her death, to his or her estate or designated beneficiary, in one lump sum within the time frame set forth in subsection (b) above and the Participant shall have no rights or interests in the Plan thereafter. (e) Voluntary Termination of Employment by Participant. In the event of a Participant's voluntary termination of employment, (i) the Participant shall not earn, and Participant's Bonus Reserve Account shall not be credited with any TAVA Bonus for the Termination Year, and (ii) in the event that the prior Plan Year Bonus Amount has not yet been paid, the Participant shall not earn, and the Participant's Bonus Reserve Account shall not be credited with, any TAVA Bonus for such prior Plan Year. The full amount of the Participant's Bonus Reserve Account (if a positive balance then exists) shall be considered earned as of the termination date and shall be paid by the Company to the former Participant in one lump sum within the time frame set forth in subsection (b) above and the Participant shall have no rights or interests in the Plan thereafter. (f) Termination by the Company for Cause. In the event the Participant's employment is terminated by the Company for Cause, (i) the Participant shall not earn, and Participant's Bonus Reserve Account shall not be credited with, any TAVA Bonus for the Termination Year, and (ii) in the event that the prior Plan Year Bonus Amount has not yet been paid, the Participant shall not earn, and Participant's Bonus Reserve Account shall not be credited with, any TAVA Bonus for such prior Plan Year. The full amount of the Participant's Bonus Reserve Account (if a positive balance then exists) shall be forfeited in its entirety as of the termination date and the Participant shall have no rights or interests in the Plan thereafter. (g) Workers' Compensation. If during any Plan Year a Participant is not on payroll due to an authorized leave of absence, or leaves payroll through Workers' Compensation, the amount of his or her TAVA Bonus shall be determined in accordance with Section 5 of the Plan, multiplied by a fraction, the numerator of which shall equal the total number of days of the Plan Year a Participant is not on payroll, and the denominator of which shall equal 365. (h) Ineligibility. If an employee's participation in the Plan is terminated for reasons other than set forth in subsections (d) through (g), whether due to changes in the Participant's 6 employment status with the Company or a Subsidiary, or due to employment with an affiliate of the Company that is not a Subsidiary, (i) the amount of his or her TAVA Bonus shall be determined in accordance with subsection (d) of this Section, whereby the Termination Year shall be the Plan Year in which participation in the Plan terminates and the numerator of the Completion Multiple shall equal the total number of days during the Termination Year in which the employee was a Participant in the Plan, and (ii) the entire amount of the Bonus Reserve Account shall be paid to the former Participant on or before the 60th day following the end of the Termination Year.
