                         DEREGISTRATION OF SECURITIES

     A Registration Statement on Form S-3 (Registration Nos. 333-48552 and
333-48552-01) was originally filed with the U.S. Securities and Exchange
Commission (the "Commission") on October 25, 2000 by the Registrants (the
"Registration Statement"). The total principal amount of securities registered
by the Registrants under the Registration Statement was $300,000,000, of which
$150,000,000 remain unsold. On December 20, 2001, BancWest Corporation merged
with a subsidiary of BNP Paribas, as a result of which BancWest Corporation
became a wholly owned subsidiary of BNP Paribas. The offering of the
securities by the Registrants has subsequently been terminated.

     Pursuant to the undertaking of the Registrants contained in the section
in Part II of the Registration Statement entitled "Undertakings", the
Registrants hereby request that the unsold Capital Securities, Guarantees, and
Junior Subordinated Debentures be removed from registration by means of this
Post-Effective Amendment No. 1.

     The Registrants intend to carry forward any excess registration fees they
paid in connection with the Registration Statement to be used in future
registrations pursuant to Rule 457(p) under the Securities Act.
