Excluding the charge related to SFAS No. 133, this represents a 7.1% year to year increase in diluted FFO per share.

Net income before the charge related to SFAS No. 133 and gain (loss) on the sale of real estate, totaled $54.9 million or $0.59 per share diluted in the third quarter of 2001 as compared to $37.1 million or $0.53 per share diluted for the same period in 2000.
