<FN> On June 30, 1997, the Company's subsidiary, Mid-States Development, Inc.
acquired Chassis Liner Corporation (Chassis Liner). The acquisition has been
accounted for as a pooling of interests. Accordingly the Company's 1996 interim
and year end, and 1997 first quarter financial statements have been restated to
include Chassis Liner. The summary financial information included in this
exhibit reflect those restatements. The Company has not provided restated
financial information prior to 1996 because the impact of Chassis Liner on
those periods was determined to be immaterial and of insignificant value to
warrant restatement.
