Adjusted EBITDA is defined as EBITDA as stated in the Company’s 2011, 2012 and 2013 consolidated audited financial statements, subject to the following adjustments:

· Gain or loss on the sale of an asset, investment or securities

3. Performance Calculation. At the end of the Performance Period the performance measure will be calculated to determine achievement against goal, and the final number of Units may be adjusted according to the following schedule:

Cumulative three-year Adjusted EBITDA Achievement Against Goal		Percentage of Units Awarded
80	%	0	%
100	%	100	%
120	%	200	%

Interpolation will be used to determine the final number of Units, should results fall in between the achievement levels outlined above. Fractional Units will not be issued. If interpolation results in fractional Units, number of Units actually awarded to Participant will be rounded up or down to the nearest whole number.

4. Vesting.

(a) Vesting Date. All Units not previously forfeited in accordance with the provisions of subsection (b), below, will vest on March 1, 2014, and will be converted to shares of common stock at a ratio of one Unit for one share of common stock.
