Registration fees will be paid subsequently on a "pay-as-you-go" basis in one or more offerings to be made hereunder. 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.</ffd:OfferingNote>
