Accordingly, the Company is filing these Post-Effective Amendments to the Registration Statements pursuant to Rule 478 under the Securities Act of 1933, as amended, to hereby terminate the effectiveness of the Registration Statements, and in accordance with the undertakings made by the Company in the Registration Statements to remove from registration, by means of these Post-Effective Amendments, any of the securities that had been registered but remain unsold at the termination of the offering, the Company hereby removes from registration all such securities, if any. Each Registration Statement is hereby amended, as appropriate, to reflect the deregistration of all such securities.
