(1) the principal of, premium, if any, and interest, if any, on the Notes will be promptly paid in full when due, whether at maturity, by acceleration, redemption or otherwise, and interest on the overdue principal of, premium on, if any, irrespective of the validity and enforceability of the Indenture, the Notes or the obligations of the Company under the Indenture or the Notes, and interest, if any, on, the Notes, if lawful, and all other obligations of the Company to the Holders or the Trustee under the Indenture or the Notes will be promptly paid in full or performed, all in accordance with the terms under the Indenture or the Notes; and
(2) in case of any extension of time of payment or renewal of any Notes or any of such other obligations, that same will be promptly paid in full when due or performed in accordance with the terms of the extension or renewal, whether at Stated Maturity, by acceleration or otherwise.
Failing payment when due of any amount so guaranteed or any performance so guaranteed for whatever reason, the Guarantor will be obligated to pay the same immediately. The Guarantor agrees that this is a guarantee of payment and not a guarantee of collection.
(b) The Guarantor hereby agrees that its obligations under the Indenture and the Notes are full and unconditional, irrespective of the validity, regularity or enforceability of the Indenture or the Notes, the absence of any action to enforce the same, any waiver or consent by any Holder of the Notes with respect to any provisions of the Indenture or the Notes, the recovery of any judgment against the Company, any action to enforce the same or any other circumstance which might otherwise constitute a legal or equitable discharge or defense of the Guarantor. The Guarantor hereby waives diligence, presentment, demand of payment, filing of claims with a court in the event of insolvency or bankruptcy of the Company, any right to require a proceeding first against the Company, protest, notice and all demands whatsoever and covenants that this Note Guarantee will not be discharged except by complete performance of the obligations contained in the Indenture and the Notes.
(c) If any Holder or the Trustee is required by any court or otherwise to return to the Company, the Guarantor or any custodian, trustee, liquidator or other similar official acting in relation to either the Company or the Guarantor, any amount paid by either to the Trustee or such Holder, this Note Guarantee, to the extent theretofore discharged, will be reinstated in full force and effect.
(d) The Guarantor agrees that it will not be entitled to any right of subrogation in relation to the Holders in respect of any obligations guaranteed hereby until payment in full of all obligations guaranteed hereby. The Guarantor further agrees that, as between the Guarantor, on the one hand, and the Holders and the Trustee, on the other hand, (1) the maturity of the obligations guaranteed hereby may be accelerated as provided in Article VII for the purposes of this Note Guarantee, notwithstanding any stay, injunction or other prohibition preventing such
