In addition, if the Company is traded on a recognized national exchange, including the NYSE American LLC or NASDAQ while Mr. Wolf is employed by the Company and the market capitalization of the Company is in excess of $500 million for at least fifteen (15) consecutive trading days, then Mr. Wolf will be entitled to receive an additional stock option equal to 2% of the then outstanding shares of Common Stock, with an exercise price equal to the then current market price as determined in good faith by the Board of Directors of the Company.
