(b) In addition to the limitation set forth in subsection (a) of this Section 2.4, the Company will not, and will not permit any Subsidiary to, incur any Indebtedness if the ratio of Consolidated Income Available for Debt Service to the Annual Debt Service Charge for the four consecutive fiscal quarters most recently ended prior to the date on which such additional Indebtedness is to be incurred shall have been less than 1.5:1, on a pro forma basis after giving effect thereto and to the application of the proceeds therefrom, and calculated on the assumption that (i) such Indebtedness and any other Indebtedness incurred by the Company and its Subsidiaries since the first day of such four-quarter period and the application of the proceeds therefrom, including to refinance other Indebtedness, had occurred at the beginning of such period; (ii) the repayment or retirement of any other Indebtedness by the Company and its Subsidiaries since the first day of such four-quarter period had been repaid or retired at the beginning of such period (except that, in making such computation, the amount of Indebtedness under any revolving credit facility shall be computed based upon the average daily balance of such Indebtedness during such period); (iii) in the case of Acquired Indebtedness or Indebtedness incurred in connection with any acquisition since the first day of such four-quarter period, the related acquisition had occurred as of the first day of such period with the appropriate adjustments with respect to such acquisition being included in such pro forma calculation and (iv) in the case of any acquisition or disposition by the Company or its Subsidiaries of any asset or group of assets since the first day of such four-quarter period, whether by merger, stock purchase or sale, or asset purchase or sale, such acquisition or disposition or any related repayment of Indebtedness had occurred as of the first day of such period with the appropriate adjustments with respect to such acquisition or disposition being included in such pro forma calculation.

(c) In addition to the limitations set forth in subsections (a) and (b) of this Section 2.4, the Company will not, and will not permit any Subsidiary to, incur any Indebtedness secured by any Encumbrance upon any of the property of the Company or any Subsidiary if, immediately after giving effect to the incurrence of such additional Indebtedness and the application of the proceeds thereof, the aggregate principal amount of all outstanding Indebtedness of the Company and its Subsidiaries (determined on a consolidated basis in accordance with GAAP) which is secured by any Encumbrance on property of the Company or any Subsidiary is greater than 40% of the sum of (without duplication) (i) the Total Assets of the Company and its Subsidiaries as of the end of the calendar quarter covered in the Company’s Annual Report on Form 10-K or Quarterly Report on Form 10-Q, as the case may be, most

9

recently filed with the Commission (or, if such filing is not permitted under the Exchange Act, with the Trustee) prior to the incurrence of such additional Indebtedness and (ii) the purchase price of any real estate assets or mortgages receivable acquired, and the amount of any securities offering proceeds received (to the extent that such proceeds were not used to acquire real estate assets or mortgages receivable or used to reduce Indebtedness), by the Company or any Subsidiary since the end of such calendar quarter, including those proceeds obtained in connection with the incurrence of such additional Indebtedness.

(d) The Company and its Subsidiaries may not at any time own Total Unencumbered Assets equal to less than 150% of the aggregate outstanding principal amount of the Unsecured Indebtedness of the Company and its Subsidiaries on a consolidated basis.

(e) For purposes of this Section 2.4, Indebtedness shall be deemed to be “incurred” by the Company or a Subsidiary whenever the Company or such Subsidiary shall create, assume, guarantee or otherwise become liable in respect thereof.

If the 3.000% Notes are only partially redeemed by the Company, the Trustee shall select which 3.000% Notes are to be redeemed by lot or in a manner it deems fair and appropriate in accordance with the terms of the Indenture.
