Separate consideration may or may not be received for securities that are issuable upon settlement, exercise, conversion or exchange of other securities or that are issued in units.

The registrant is relying on Rule 456(b) and Rule 457(r) under the Securities Act of 1933, as amended, to defer payment of all of the registration fee. In connection with the securities offered hereby, the registrant will pay "pay-as-you-go registration fees" in accordance with Rule 456(b). The registrant will calculate the registration fee applicable to an offer of securities pursuant to this registration statement based on the fee payment rate in effect on the date of such fee payment.
