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 its
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 net income 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,
(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 stock or 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).
