In case of the failure of the Company to make any such payment of principal (or premium, if any) or interest, the Guarantor hereby agrees to cause any such payment to be made when and as the same shall become due and payable by acceleration, call for redemption or otherwise, as if such payment were made by the Company.
The Guarantor hereby agrees that its obligations hereunder shall be unconditional, irrespective of the validity, regularity or enforceability of such Note or the Indenture, the absence of any action to enforce the same, any waiver or consent by the Holder of such Note or by the Trustee with respect to any provisions thereof or of the Indenture, the obtaining of any judgment against the Company or any action to enforce the same or any other circumstances which might otherwise constitute a legal or equitable discharge or defense of a guarantor.
