EXHIBIT 12.1

                COMPUTATION OF RATIO OF EARNINGS TO FIXED CHARGES
   AND RATIO OF EARNINGS TO COMBINED FIXED CHARGES AND PREFERRED DISTRIBUTIONS

         The ratio of earnings to fixed charges for the Company (including
subsidiaries and majority-owned partnerships) presents the relationship of the
Company's earnings to its fixed charges. "Earnings" as used in the computation,
is based on the Company's earnings attributable to OP Units from operations
(which includes a charge to income for depreciation and amortization expense)
plus fixed charges. "Fixed charges" is comprised of (i) interest charges,
whether expensed or capitalized, and (ii) amortization of loan costs and
discounts or premiums relating to indebtedness of the Company and its
subsidiaries and majority-owned partnerships, excluding in all cases items which
would be or are eliminated in consolidation, and (iii) preferred OP Unit
distributions.

         The Company's ratio of earnings to combined fixed charges presents the
relationship of the Company's earnings (as defined above) to fixed charges (as
defined above).
