Each component of EBITDA shall be obtained directly from the audited consolidated financial statements of the Company and its Subsidiaries for the applicable year.

(iv) “ Dividends ” means the sum of all ordinary and extraordinary dividends paid during the Performance Period with respect to the applicable share of Common Stock.

(xii) “ Total Shareholder Return ” or “ TSR ” means a fraction, the numerator of which is the Ending Price plus Dividends minus the Beginning Price, and the denominator of which is the Beginning Price.

II.     Calculation of Performance Unit Final Value

Cumulative EBITDA . The Cumulative EBITDA attainment level shall be determined as follows:

Threshold Level:    $____

Target Level:    $____

Maximum Level:    $____

Cumulative EBITDA shall be weighted eighty percent (80%) in the calculation of the Final Value and shall contribute to the Final Value as follows:

Relative TSR . The Total Shareholder Return of the Company and of the Comparison Companies shall be calculated and certified by the Committee. The percentile ranking of the Company’s Total Shareholder Return as compared to the Total Shareholder Return of each Comparison Company shall determine the Final Value for relative TSR as follows:

Threshold Level:    30 ^th Percentile

Target Level:    50 ^th Percentile

Maximum Level:    90 ^th Percentile

If, during the Performance Period, any Comparison Company is party to a merger, acquisition or disposition and such event, in the Committee’s determination, has significantly altered the Comparison Company, then the Committee may in its discretion remove the Comparison Company

from the relative TSR calculation; provided, however, that no additional company shall be substituted. Regardless of the actual Final Value determined in accordance with this Schedule I , if the Company’s Total Shareholder Return during the Performance Period is negative, the relative TSR shall not exceed the target level.

Relative TSR shall be weighted twenty percent (20%) in the calculation of the Final Value and shall contribute to the Final Value as follows:

Final Value . The aggregate value of Performance Units that shall vest as of the Scheduled Vesting Date shall be equal to the product of (i) the number of Performance Units, multiplied by (ii) the Final Value. The Final Value shall be equal to the sum of the contribution value attributed to the level achieved for each of Cumulative EBITDA and relative TSR. In no event shall the Final Value exceed $200 per Performance Unit. If the performance ranking is below threshold for both Cumulative EBITDA and relative TSR, the Final Value shall be zero. The Final Value shall be determined in accordance with the tables above for each of Cumulative EBITDA and relative TSR with interpolation between the specified levels.
