The Statement relates to a tender offer by Whitcomb Acquisition Corp., a

in cash, less any required withholding taxes and without interest thereon, upon
the terms and subject to the conditions set forth in the related offer to
purchase dated January 27, 2003 (the "Offer to Purchase"), and in the related
