Such exclusion is contingent upon certain conditions, including the consummation of the Transaction on or before April 1, 2004. Due to pending regulatory approvals, the Issuer has requested that the Current Holders extend such date until April 30, 2004.

Such amendment is referred to herein as the “Amendment”.
