(1)      For 1997, we had total fixed charges of $10,011 and total fixed charges
         and preferred stock dividends of $10,879 compared to earnings of $618.
         This resulted in a shortfall of earnings over fixed charges of $9,393,
         and a shortfall of earnings over combined fixed charges and preferred
         stock dividends of $10,261. During 1997, the Company recorded a
         non-cash, unusual charge of $19,220 related to the termination of the
         management contract. Excluding the effects of this unusual charge, the
         ratio of earnings to fixed charges and the ratio of earnings to
         combined fixed charges and preferred stock dividends would have been
         1.98x and 1.82x, respectively for 1997.

(2)      For 1998, we had total combined fixed charges and preferred stock
         dividends of $24,284 compared to earnings of $23,099. This resulted in
         a shortfall of earnings over combined fixed charges and preferred stock
         dividends of $1,185. During 1998, the Company recorded a non-cash,
         unusual charge of $12,047 related to 495,509 OP units accrued according
         to the 1997 termination of the management contract. Excluding the
         effects of this unusual charge, the ratio of earnings to fixed charges
         and the ratio of earnings to combined fixed charges and preferred stock
         dividends would have been 2.05x and 1.45x, respectively for 1998.
