Debt Instrument, Debt Default, Description of Notice of Default		The non-payments constituted an event of default under the Indenture governing the Debentures. The trustee, by notice to the Company, or the holders of 25% of the principal amount of the Debentures outstanding, by notice to the Company and the trustee, may declare the outstanding principal plus interest due and payable immediately. During the continuation of any event which, with notice or lapse of time or both, would constitute a default under any agreement under which Senior Indebtedness is issued, if the effect of such default is to cause or permit the holder of Senior Indebtedness to become due prior to its stated maturity, no payment (including any required sinking fund payments) of principal, premium or interest shall be made on the Debentures unless and until such default shall have been remedied, if written notice of such default has been given to the trustee by the Company or the holder of Senior Indebtedness.
