This assumes a spread over LIBOR of 3.5% (the spread can range from 3.25% to 4.0% depending on leverage levels) and assumes LIBOR of 1.5% (the facility requires a minimum LIBOR rate, or floor, of 1.5%). - There are no borrowings assumed in 2010 under the $250 million secured revolving line of credit. Accordingly, interest expense above includes costs associated with the 0.5% unused fee applied to the entire $250 million amount during 2010. Three Months Ended Actual Estimated
