Borrower Obligation and will forthwith make full payment of any amount due with respect thereto at its sole cost and expense.

(b) The Guarantor hereby waives any right, whether legal or equitable, statutory or non-statutory, to require the Lender to proceed against or take any action against or pursue any remedy with respect to the Borrower or any other Person or make presentment or demand for performance or give any notice of nonperformance before the Lender may enforce its rights hereunder against the Guarantor in its capacity as Guarantor.

(c) The obligations of the Guarantor to the extent set forth hereunder shall remain in full force and effect until the Borrower Obligations shall have been performed in full. If at any time any performance by any Person of any Borrower Obligation is rescinded or must be otherwise restored or returned, whether upon the insolvency, bankruptcy or reorganization of the Borrower or otherwise, the Guarantor’s obligations hereunder with respect to such Borrower Obligation shall be reinstated at that time as though that Borrower Obligation had become due and had not been performed.
