(1) Not specified as to each class of securities to be registered, pursuant to General Instruction II.E. of Form S-3. An indeterminate aggregate initial offering price or number of the securities of each identified class is being registered as may from time to time be offered at indeterminate prices. Separate consideration may or may not be received for securities that are issuable on exercise, conversion or exchange of other securities, including under any anti-dilution provisions, or that are issued in units or represented by depositary shares. Securities registered hereunder may be sold separately or in any combination with other securities registered hereunder.

(2) Exclusive of accrued interest, distributions and dividends, if any.

(3) In reliance on Rules 456(b) and 457(r) under the Securities Act of 1933, as amended, the Registrant is deferring payment of the registration fee.

(4) Each depositary share will be issued under a deposit agreement and will be evidenced by a depositary receipt. In the event the Registrant elects to offer to the public fractional interests in preferred shares of beneficial interest registered hereunder, depositary receipts will be distributed to those persons purchasing such fractional interests, and preferred shares of beneficial interest will be issued to the depositary under the deposit agreement. No separate consideration will be received for the depositary shares.
