ITEM 2.02 RESULTS OF OPERATIONS AND FINANCIAL CONDITION

     On Friday, February 10, 2006, the Registrant filed schedules reporting 2005
sales by quarter excluding Efen and 2005 income by quarter reflecting Efen as a
discontinued operation in accordance with FAS144 ("Accounting for the Impairment
or Disposal of Long-Lived Assets"). The sales schedule and income statement
amounts for the fourth quarter and year to date are unchanged from those
contained in the press release dated February 8, 2006. The sales for the first
three quarters of 2005 have been revised from the sales reported in previously
filed Form l0-Qs for the related periods to exclude sales from Efen (a
discontinued operation). The income statements for the first three quarters have
been revised to reflect Efen as a discontinued operation. The impact of treating
Efen as a discontinued operation is shown primarily by the line item entitled
"Discontinued operations (net of tax)". The third quarter income statement has
also been revised to reflect Ireland severance costs attributable to the third
quarter as discussed in the press release dated February 8, 2006. These
schedules are part of this Form and attached as Exhibit 99.1.
