WHEREAS, pursuant to that certain Restructuring Agreement, dated as of March 3, 1993 (the “Restructuring Agreement”) between Holding and KIA IV, KIA IV agreed to acquire from Holding, and Holding agreed to issue to KIA IV, $55,000,000 in aggregate principal amount of Series A Variable Rate Senior Notes (the “Series A Notes”) and certain warrants for the purchase of shares of common stock of Holding;

WHEREAS, pursuant to that certain Indenture, dated as of May 22, 2002 (the “Indenture”) between the Company and The Bank of New York, and as set forth in that certain Offering Circular of the Company, dated May 17, 2002 (the “Offering”), the Company issued $250,000,000 in aggregate principal amount of its 9¾% Senior Secured Notes due 2012 (the “Senior Secured Notes”);

WHEREAS, the net proceeds of the Offering were used, among other things, to pay a dividend to Holding in the amount of $25,000,000 to enable Holding to (x) pay principal and accrued interest on Holding’s indebtedness to KIA IV (the “Holding Notes”) and/or (y) to redeem or repurchase capital stock of Holding, subject to the terms of the Restructuring Agreement.

WHEREAS, the Holding Notes provide that Holding shall apply all Excess Cash Flow to the payment of interest due under the outstanding Holding Notes if and to the extent that on any Interest Payment Date (as defined in the Holding Notes) the aggregate interest payments due under the Holding Notes then outstanding exceeds the Excess Cash Flow of Holding for the preceding six-month period, or in lieu thereof to issue an additional note (a “Secondary Note”) in an aggregate principal amount equal to the amount of such excess interest;

WHEREAS, the $25,000,000 dividend paid to Holding in connection with the Offering constitutes Excess Cash Flow of Holding; and

WHEREAS, as of June 30, 2002, Holding and KIA IV entered into a Third Amendment to the Restructuring Agreement extending the due date for any Excess Cash Flow payment in order to allow Holding to explore strategic alternatives for itself and to retain the $25,000,000 dividend and any earnings thereon until October 1, 2002.

WHEREAS, Holding and KIA IV have agreed to further extend the due date for any Excess Cash Flow payment to January 1, 2003.
