On October 15, 2015, the board of directors of Ensor Materials Corporation approved a stock option plan for
key executives. On January 1, 2016, 20 million stock options were granted, exercisable for 20 million shares of
Ensor’s $1 par common stock. The options are exercisable between January 1, 2019, and December 31, 2021,
at 80% of the quoted market price on January 1, 2016, which was $15. The fair value of the 20 million options,
estimated by an appropriate option pricing model, is $6 per option.
Two million options were forfeited when an executive resigned in 2017. All other options were exercised on
July 12, 2020, when the stock’s price jumped unexpectedly to $19 per share.
