Notwithstanding any other provision of this Supplemental Indenture, the provisions of this Supplemental Indenture are expressly and solely for the benefit of the Notes.


Section 1.02 Effect of Supplemental Indenture.

ARTICLE II


EVENTS OF DEFAULT


Section 2.01 Events of Default. With respect to the Notes only, Section 5.01 of the Base Indenture shall be amended and restated in its entirety as follows:


Event of Default Defined; Acceleration of Maturity; Waiver of Default. “Event of Default”, with respect to the Notes wherever used herein, means each one of the following events which shall have occurred and be continuing (whatever the reason for such Event of Default and whether it shall be voluntary or involuntary or be effected by operation of law or pursuant to any judgment, decree or order of any court or any order, rule or regulation of any administrative or governmental body):


(a) default in the payment of any installment of interest upon any of the Notes as and when the same shall become due and payable, and continuance of such default for a period of 30 days; or


(b) default in the payment of all or any part of the principal on any of the Notes as and when the same shall become due and payable either at maturity, upon redemption, by declaration or otherwise, and the continuance of such default; or


(c) default in the performance, or breach, of any covenant or warranty of the Issuer in respect of the Notes (other than a default specified in clauses (a) or (b) above) and continuance of such default or breach for a period of 60 days after there has been given, by registered or certified mail, to the Issuer by the Trustee or to the Issuer and the Trustee by the Holders of at least 25% in principal amount of the Notes, a written notice specifying such default or breach and requiring it to be remedied and stating that such notice is a “Notice of Default” hereunder;


(d) (1) a default by the Issuer or any of its Subsidiaries in the payment of any principal at maturity of any Indebtedness (other than the Notes) aggregating more than $50,000,000 in principal amount, when due and payable after giving effect to any applicable grace period; or (2) a default by the Issuer or any of its Subsidiaries in the performance of any other term or provision of any Indebtedness (other than the Notes) aggregating more than $50,000,000 in principal amount that results in such Indebtedness becoming or being declared due and payable prior to the date on which it would otherwise become due and payable, and such acceleration shall not have been rescinded or annulled or such indebtedness shall not have been discharged within a period of 30 days after there has been given to the Issuer by the Trustee or given to the 









Issuer and the Trustee by the Holders of at least 25% in aggregate principal amount of the outstanding Notes, a written notice specifying such default or defaults; provided, however, that if the default under such Indebtedness is cured, or waived by the holders of the Indebtedness, in each case as permitted by the governing instrument, then the event of default caused by such default will be deemed likewise to be cured or waived; or


(e) a court having jurisdiction in the premises shall enter a decree or order for relief in respect of the Issuer in an involuntary case under any applicable bankruptcy, insolvency or other similar law now or hereafter in effect, or appointing a receiver, liquidator, assignee, custodian, trustee or sequestrator (or similar official) of the Issuer or for all or substantially all of its property and assets or ordering the winding up or liquidation of its affairs, and such decree or order shall remain unstayed and in effect for a period of 60 consecutive days; or 


(f) the Issuer shall commence a voluntary case under any applicable bankruptcy, insolvency or other similar law now or hereafter in effect, or consent to the entry of an order for relief in an involuntary case under any such law, or consent to the appointment of or taking possession by a receiver, liquidator, custodian, trustee or sequestrator (or similar official) of the Issuer or for any substantial part of its property and assets, or make any general assignment for the benefit of creditors.


If an Event of Default described in clauses (a), (b), (c) or (d) occurs and is continuing, then, and in each and every such case, unless the principal of all of the Notes shall have already become due and payable, either the Trustee or the Holders of not less than 25% in aggregate principal amount of the Notes then outstanding hereunder, by notice in writing to the Issuer (and also to the Trustee if given by Holders), may declare the entire principal of all of the Notes and the interest accrued thereon, if any, to be due and payable immediately, and upon any such declaration the same shall become immediately due and payable. If an Event of Default described in clauses (e) or (f) occurs and is continuing, then and in each and every such case, the entire principal of all the Notes then outstanding and interest accrued thereon, if any, shall become immediately due and payable.


The foregoing provisions, however, are subject to the condition that if, at any time after the principal of the Notes shall have been so declared due and payable, and before any judgment or decree for the payment of the moneys due shall have been obtained or entered as hereinafter provided, the Issuer shall pay or shall deposit with the Trustee a sum sufficient to pay all matured installments of interest upon all the Notes and the principal of any and all Notes which shall have become due otherwise than by acceleration (with interest upon such principal and, to the extent that payment of such interest is enforceable under applicable law, on overdue installments of interest, at the same rate as the rate of interest specified in the Notes to the date of such payment or deposit) and such amount as shall be sufficient to cover reasonable compensation of the Trustee, its agents, attorneys and counsel, and all other expenses and liabilities incurred, and all advances made, by the Trustee except as a result of negligence or bad faith, and if any and all Events of Default under the Indenture, other than the non-payment of the principal of Notes which shall have become due by acceleration, shall have been cured, waived or otherwise remedied as provided herein-then and in every such case the Holders of a majority in aggregate principal amount of all the Notes then outstanding, by written notice to the Issuer and to the Trustee, may waive all defaults with respect to all the Notes and rescind and annul such declaration and its consequences, but no such waiver or rescission and annulment shall extend to or shall affect any subsequent default or shall impair any right consequent thereon.
