For purposes of calculating the dollar denominated exercise price per Common Share, the exercise price of JPY 1,300 per Common Share has been converted to U.S. Dollars at the exchange rate of JPY 156.6400= US$1.00, which was the foreign exchange rate on May 8, 2026, as reported by the U.S. Federal Reserve in its weekly release on May 11, 2026. The exercise price is the actual Japanese Yen amount regardless of the exchange rate on the date of exercise.
