Pursuant to the Plan, a Non Qualified Stock Option becomes exercisable as to 10 percent of the shares of the common stock underlying the option at the end of each three-month period following the date of grant until exercisable in full.  The reporting person's Non Qualified Stock Option award became exercisable in full on December 1, 2013. Each option granted under the Plan expires 10 years from the date the option is granted, unless terminated earlier in accordance with the Plan.</footnote>
