The entirety of the Second Fee will continue to be applied to the Unsold Shares. In accordance with Rule 415(a)(6), the offering of the Unsold Shares registered under the Second Registration Statement will be terminated as of the date of effectiveness of this Registration Statement.Pursuant to Rule 416(a) under the Securities Act, this Registration Statement also covers any additional securities that may be offered or issued hereunder as a result of stock splits, stock dividends or similar transactions.</ffd:OfferingNote>
