The proposed maximum offering price per security 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 General Instruction II.D of Form S-3 under the Securities Act . The registration fee has been calculated in accordance with Rule 457(o) under the Securities Act based on the proposed maximum aggregate offering price of all securities listed.</ffd:OfferingNote>
