 1.8              Exculpation.  Subject to the terms of the next succeeding paragraph and notwithstanding anything to the contrary otherwise contained in this Guaranty, but without in any way releasing, impairing or otherwise affecting this Guaranty or any of the Loan Documents (including without limitation any guaranties or indemnification agreements) or those certain Environmental Indemnification Agreements to which Borrower or any Guarantor is a party, or the validity hereof or thereof, or the lien of the Mortgage or of any Guarantor Second Mortgage, it is agreed that, with respect to each Guarantor, Lender’s source of satisfaction of the Guaranteed Obligations and the other obligations of each Guarantor hereunder is limited to (a) the “Premises” of such Guarantor (as defined in the Guarantor Second Mortgage executed by such Guarantor; such “Premises” is sometimes referred to in this Section 1.8 as the “Guarantor Premises”) and proceeds thereof, and (b) rents, income, issues, proceeds and profits arising out of the Guarantor Premises of such Guarantor after an Event of Default (as that term is hereafter defined); provided, however, that nothing herein contained shall be deemed to be a release or impairment of the Guaranteed Obligations or the security therefor intended by the Guarantor Second Mortgages, or be deemed to preclude Lender from foreclosing one or more of the Guarantor Second Mortgages or from enforcing any of Lender’s rights or remedies in law or in equity thereunder, or in any way or manner affecting Lender’s rights and privileges under any of the Loan Documents or any separate guaranty or indemnification agreements guarantying the Guaranteed Obligations.

 ARTICLE III.
 DEFAULTS AND REMEDIES
  
 3.1              Event of Default.  The occurrence of any one or more of the following events shall constitute an Event of Default under the provisions of this Guaranty, and the term “Event of Default” as used in this Guaranty shall mean the occurrence of any one or more of the following events: (a) the failure of Guarantor to promptly pay or perform all or any part of the Guaranteed Obligations, (b) any representation or warranty made herein or any financial statement or other information furnished by Guarantor pursuant hereto shall prove to have been false or misleading in any material respect on the date as of which the same was made or furnished, (c) the failure of Guarantor to observe, perform and comply with any of the covenants set forth in Section 2.2 of this Guaranty, and such failure shall continue uncured for a period of ten (10) days from the date of notice thereof from the Lender to Guarantor, or (d) the commencement or filing of any proceedings by or against Guarantor or any of Guarantor’s assets or properties under the provisions of any bankruptcy, reorganization, arrangement, insolvency, receivership, liquidation or similar law for the relief of debtors, and, except with respect to any such proceedings instituted by Guarantor, are not discharged within sixty (60) days of their commencement.
  
 3.2              Rights and Remedies.  Upon the occurrence of an Event of Default under the provisions of this Guaranty, an amount equal to the total of the Guaranteed Obligations then outstanding (whether matured or unmatured and regardless of whether any portion of such Guaranteed Obligations are then due and payable by the Borrower) shall immediately and automatically be due and payable by Guarantor to Lender without further action by, or notice of any kind from, Lender unless expressly provided for herein, and the Lender may at any time and from time to time thereafter exercise any powers, rights and remedies available to the Lender under the provisions of this Guaranty, the Loan Documents and applicable laws to enforce and collect the obligations and liabilities of Guarantor hereunder, all such powers, rights and remedies being cumulative and enforceable alternatively, successively or concurrently.  Guarantor shall pay to Lender on demand the amount of any and all costs and expenses, including, without limitation, court costs and attorney’s fees and expenses, paid or incurred by or on behalf of the Lender in exercising any such powers, rights and remedies, together with interest thereon from the date due until paid in full at the Default Rate (as defined in the Note).  Each and every Event of Default hereunder shall give rise to a separate cause of action hereunder, and separate actions may be brought hereunder as each cause of action arises.  No failure or delay by the Lender in one or more instances to require strict performance by Guarantor of any of the provisions hereof or to exercise any powers, rights or remedies available to it under the provisions of this Guaranty, the Loan Documents or applicable laws shall operate as a waiver thereof or preclude Lender at any later time or times from demanding strict performance thereof or exercising any such powers, rights or remedies.  No conduct, custom or course of dealing shall be effective to waive, amend, modify or release this Guaranty.  No modification or waiver of any of the provisions of this Guaranty shall be effective unless it is in writing and signed by the Lender, and any such waiver shall be effective only in the specific instance and for the specific purpose for which it is given.
  
 3.3              Effect Of Bankruptcy Proceedings.  This Guaranty shall continue to be effective, or be automatically reinstated, as the case may be, if at any time payment, in whole or in part, of any of the Guaranteed Obligations is rescinded or must otherwise be restored or returned by Lender as a preference, fraudulent conveyance or otherwise under any bankruptcy, insolvency or similar law, all as though such payment had not been made.  If an Event of Default at any time shall have occurred and be continuing or exist and declaration of default or acceleration under or with respect to any of the Loan Documents shall at such time be prevented by reason of the pendency against Borrower of a case or proceeding under any bankruptcy or insolvency law, Guarantor agrees that, for purposes of this Guaranty and Guarantor’s obligations hereunder, such Loan Documents shall be deemed to have been declared in default or accelerated with the same effect as if such Loan Documents had been declared in default and accelerated in accordance with the terms thereof, and Guarantor shall forthwith pay the Guaranteed Obligations in full without further notice or demand.
