|(a) | Includes annual dividend requirements of $12.6 million for the Monthly Income Preferred Securities (MIPS) per year for 2002 and prior. For 2003, only $6.3 million is included for
the period January 1  June 30. From July 1, 2003 until their redemption in 2004, MIPS dividends were included with interest on long-term debt due to the adoption of SFAS No. 150.

|(b) | In order to achieve a ratio of earnings to fixed charges and preferred and preference stock dividend requirements of one to one, Total Earnings would need to increase by
approximately $122 million.
