In case of the failure of the Issuer promptly to make any such payment of principal (and premium, if any, on) or interest, the New Guarantor hereby agrees to make any such payment to be made promptly when and as the same shall become due and payable, whether at the Stated Maturity or by declaration of acceleration, call for redemption or otherwise, and as if such payment were made by the Issuer.

(b) The New Guarantor hereby agrees that its obligations hereunder shall be as if it were principal debtor and not merely surety, and shall be absolute and unconditional, joint and several, irrespective of, and shall be unaffected by any failure to enforce the provisions of such Security or the Indenture, or any waiver, modification or indulgence granted to the Issuer with respect thereto, by the Holder of such Security or the Trustee for the Securities of such series or any other circumstance which may otherwise constitute a legal or equitable discharge of a surety or guarantor; provided, however, that, notwithstanding the foregoing, no such waiver, modification or indulgence shall, without the consent of the New Guarantor, increase the principal amount of such Security, or increase the interest rate thereon, or increase any premium payable upon redemption thereof, or alter the Stated Maturity thereof, or increase the principal amount of any Original Issue Discount Security that would be due and payable upon a declaration of acceleration or the maturity thereof pursuant to Article Five of the Indenture. The New Guarantor hereby waives diligence, presentment, demand of payment, filing of claims with a court in the event of merger or bankruptcy of the Issuer, any right to require a proceeding first against the Issuer, protest or notice with respect to such Security or the indebtedness evidenced thereby or with respect to any sinking fund or analogous payment required under such Security and all demands whatsoever, and covenants that the Additional Guarantee of the New Guarantor will not be discharged except by payment in full of the principal of (and premium, if any, on) and interest on such Security or as otherwise set forth in the Indenture; provided, that if any Holder or the Trustee is required by any court or otherwise to return to the Issuer, the New Guarantor or any custodian, trustee, liquidator or other similar official acting in relation to either the Issuer or the New Guarantor any amount paid either to the Trustee or such Holder, the Additional Guarantee of the New Guarantor, to the extent theretofore discharged, shall be reinstated in full force and effect.

(c) The New Guarantor shall be subrogated to all rights of the Holder of such Security and the Trustee for the Securities of such series against the Issuer in respect of any amounts paid to such Holder by the New Guarantor pursuant to the provisions of its Additional Guarantee; provided, however, that the New Guarantor shall not be entitled to enforce or to receive any payments arising out of or based upon such right of subrogation until the principal of (and premium, if any, on) and interest on all Securities of the same series issued under the Indenture shall have been paid in full.

The delivery of any Securities by the Trustee, after the authentication thereof hereunder, shall constitute due delivery of the Additional Guarantee of the New Guarantor set forth in this Sixth Supplemental Indenture on behalf of the New Guarantor.

Section 205. This Article Not to Prevent Events of Default.

The failure to make a payment on account of principal of (and premium, if any, on) or interest on the Securities by reason of any provision of this Article Two of this Sixth Supplemental Indenture will not be construed as preventing the occurrence of an Event of Default.
