Accordingly, pursuant to the undertaking contained in the Registration Statements to remove from registration, by means of a post-effective amendment, any of the securities being registered which remain unsold at the termination of the offering, the Company is filing these Post-Effective Amendments to the Registration Statements to deregister all such securities of the Company registered under the Registration Statements that remain unsold as of the effective time of the Transaction, if any.
