As a result of the Merger, the Registrant has terminated all offerings of its securities pursuant to the Registration Statements.  The Registrant hereby removes from registration, by means of this Post-Effective Amendment, any and all of the securities registered under the Registration Statements that remained unsold as of the Effective Time.
