The Applicable Rate will be 6 1/2% per annum (the "Initial Rate") from the date of original issuance of the Preferred Securities to but excluding the Reset Date, and the Term Rate from the Reset Date and thereafter. The Term Rate will be the rate established by the Remarketing Agent to be effective on the Reset Date. The Applicable Rate will be increased by 0.50% per annum during the continuation of a Registration Default. Dividends in arrears for more than one quarter will bear interest thereon compounded quarterly at the Applicable Rate (to the extent permitted by applicable law). The term "Dividends" as used herein includes such quarterly Dividends, and additional Dividends on quarterly Dividends not paid on the applicable Dividend Date, as applicable. A Dividend is payable only to the extent that payments are made in respect of the Preferred Securities, to the extent the Company has funds available therefor, and when and as declared by the Board of Directors of the Company. The amount of Dividends payable for any period will be computed for any full quarterly Dividend period on the basis of a 360-day year of twelve 30-day months, and for any period shorter than a full quarterly Dividend period for which Dividends are computed, Dividends will be computed on the basis of the actual number of days elapsed per 30-day month.

The fifteenth day of the month immediately preceding each Dividend Date is the record date for determining which holders of Preferred Securities shall be paid the Dividends, if any, payable on such Dividend Date. If the Reset Date is prior to the record date for the immediately following Dividend Date, then Dividends, if any, accrued from and after the Reset Date to but excluding the immediately following Dividend Date shall be paid on such Dividend Date to the person in whose name each Preferred Security is registered on the relevant record date.
