The five-year treasury rate will be determined by the calculation agent on the third business day immediately preceding the applicable reset date. If the five-year treasury rate for any reset date cannot be determined pursuant to the methods described in the two bullet points above, the dividend rate for such reset period will be the same as the dividend rate determined for the dividend period immediately preceding the applicable reset date.
