(1) An indeterminate aggregate initial offering price and number of securities of each identified class is being registered as may from time to time be offered, issued or sold at indeterminate prices. In addition, an indeterminate number of securities that may be issued upon exercise, settlement, conversion or exchange of any offered securities, or pursuant to anti-dilution adjustments, is being registered. Separate consideration may or may not be received for securities that are issuable on exercise, conversion or exchange of other securities. Any securities registered hereunder may be sold separately or as units with other securities registered hereunder.

(2) Pursuant to Rules 456(b) and 457(r) under the Securities Act of 1933, the registrant is deferring payment of the entire registration fee. Registration fees will be paid subsequently on a “pay as you go” basis.
