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.

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. (c) Pursuant to Rule 416 under the Securities Act of 1933, as amended, or the Securities Act, the common shares of beneficial interest being registered hereunder include such indeterminate number of common shares of beneficial interest as may be issuable with respect to the shares being registered hereunder as a result of share splits, share dividends or similar transactions.
