These retainer awards are granted in satisfaction of the annual retainer compensation to be earned by the director for his service on the Issuer's Board of Directors and its Committees during 2019. The number of shares of common stock subject to such retainer award is equal to the amount of cash that would have been received had the retainers all been paid in cash, divided by the average daily closing market price of the Issuer's common stock for the month of November, rounded to the nearest 100 shares.</footnote>
