The securities registered hereunder also include such indeterminate number of shares of common stock, preferred stock and amount of debt securities as may be issued upon conversion of or exchange for debt securities that provide for conversion or exchange, upon exercise of warrants or pursuant to the antidilution provisions of any such securities. In addition, pursuant to Rule 416 under the Securities Act of 1933, as amended, or the Securities Act, the shares being registered hereunder include such indeterminate number of shares of common stock and preferred stock as may be issuable with respect to the shares being registered hereunder as a result of stock splits, stock dividends or similar transactions. The proposed maximum offering price per unit and maximum aggregate offering prices per class of securities will be determined from time to time by the Registrant in connection with the issuance by the Registrant of the securities registered hereunder and is not specified as to each class of security pursuant to Instruction 2.A.iii.c. to the Calculation of Filing Fee Tables and Related Disclosure on Item 16(b) of Form S-3 under the Securities Act. Separate consideration may or may not be received for securities that are issuable on exercise, conversion or exchange of other securities. The Registrant is relying on Rules 456(b) and 457(r) under the Securities Act, to defer payment of the registration fee, other than the registration fee due in connection with $200,000,000 of shares of common stock that may be issued and sold from time to time under the prospectus supplement included in this registration statement. Any subsequent registration fees will be paid on a pay-as-you-go basis. In connection with the securities offered hereby, the Registrant will pay "pay-as-you-go registration fees" in accordance with Rule 456(b) under the Securities Act. The Registrant will calculate the registration fee applicable to an offer of securities pursuant to this registration statement based on the fee rate in effect on the date of such fee payment. </ffd:OfferingNote>
