As

        had received a notice from
The
        Nasdaq Stock Market Inc. ("Nasdaq") that the Registrant's securities were
        subject to potential delisting due to the fact that it was not in compliance
        with the periodic filing requirement under Nasdaq Marketplace Rule 4310(c)(14)
        as a result of the Registrant's failure to file
its
        Quarterly Report on Form 10-Q for the third quarter ended September 30, 2005
        (the "Form 10-Q")
by the
        prescribed filing date.

        Registrant filed its Form 10-Q on November 21, 2005 and, on that same date,
        received a notice from Nasdaq confirming that the Registrant is now in
        compliance with the standards set forth under Nasdaq Marketplace Rule
        4310(c)(14) for continued listing on Nasdaq based on the Registrant's filing
        of
        its Form 10-Q. As a result of the Registrant's compliance with this rule,
        Nasdaq
        further notified the Registrant that the fifth character "E" will be removed
        from its trading symbol "IMCO" at the opening of business on November 23,
