This updates our previous estimate of the expected loss as reported on Form 8-K filed August 22, 2005. ITEM 2.06 -- MATERIAL IMPAIRMENTS The disclosure in Item 8.01 below relating to the expected loss on the sale of Ontelaunee that the Company expects to recognize in the third quarter of 2005, is incorporated by reference herein. ITEM 8.01 -- OTHER EVENTS On October 7, 2005, the Company issued the press release attached hereto as Exhibit 99.1. Subsequent to issuing this press release, the Company has refined its estimated loss from the sale of Ontelaunee from approximately $129 million, as disclosed in the press release, to approximately $137.2 million. The change is primarily associated with greater operating margin recorded by Ontelaunee than previously forecasted since July 1, 2005, the effective date of the sale. Under the terms of the sales agreement, Ontelaunee's operating margin subsequent to June 30, 2005, creates a downward adjustment in the purchase price. However, the increased loss on sale is offset by the favorable impact of the increased operating margin, thus resulting in no change to net income from discontinued operations.
