These shares were granted pursuant to a restricted stock unit award that vests 100% upon the earlier of the one-year anniversary of the grant date or the day prior to the company's next regular meeting of shareholders following the grant date. These shares (rounded down to the nearest whole share) represent the equity portion of the annual retainer fee in the amount of $180,000.00, with the number of restricted stock units determined by dividing the dollar amount of the fee by $22.98, the average of the high ($23.40) and low ($22.56) price of the Issuer's common stock on the date of the grant. Additional units accrue as and when dividends are paid on the Issuer's common stock.↩ 1
