Schedule 1

Target Bonus

	Percentage that Actual EBITDA for a fiscal year represents of Budgeted EBITDA for such fiscal year
	90	%	100	%	110	%
Percentage of Base Salary payable as a Bonus	20	%	80	%	120	%

The Bonus payable to the Executive hereunder for each fiscal year is to be interpolated for Actual EBITDA between 90% and 100% or between 100% and 110% of Budgeted EBITDA.

For example, if Actual EBITDA represents 95% of Budgeted EBITDA, a Bonus of 50% of the Executive’s Base Salary would be payable, calculated as follows:

(1)The increase of Actual EBITDA over the 90% of Budgeted EBITDA benchmark, which in this case equals 5%, is divided by the difference between (a) 100% and (b) 90% (the two applicable Budgeted EBITDA benchmarks), yielding 50%;

(2)This amount (50%) is then multiplied by the difference between (x) 80% (the Bonus at 100% of Budgeted EBITDA) and (y) 20% (the Bonus at 90% of Budgeted EBITDA), which equals 30% of the Executive’s Base Salary as the Target Bonus. This incremental 30% is added to the 20% Base Salary Target Bonus at 90% of Budgeted EBITDA for a total Target Bonus equal to 50% of Base Salary.

On the other hand, if Actual EBITDA represents 105% of Budgeted EBITDA, then a Bonus of 100% of the Executive’s Base Salary would be payable, calculated as follows:

(1)The increase of Actual EBITDA over the 100% of Budgeted EBITDA benchmark, which in this case equals 5%, is divided by the difference between (a) 110% and (b) 100% (the two applicable Budgeted EBITDA benchmarks), yielding 50%;

(2)This amount (50%) is then multiplied by the difference between (x) 120% (the Target Bonus at 110% of Budgeted EBITDA) and (y) 80% (the Target Bonus at 100% of Budgeted EBITDA), resulting in a 20% incremental increase in the Target Bonus, which when added to the 80% of Base Salary payable when Actual EBITDA equals 100% of Budgeted EBITDA Benchmark, yields an aggregate bonus equal to 100% of the Executive’s Base Salary.
