The execution, delivery and performance by each Debtor of this Agreement and the filings contemplated therein have been duly authorized by all necessary action on the part of such Debtor and no further action is required by such Debtor. This Agreement has been duly executed by each Debtor. This Agreement constitutes the legal, valid and binding obligation of each Debtor, enforceable against each Debtor in accordance with its terms except as such enforceability may be limited by applicable bankruptcy, insolvency, reorganization and similar laws of general application relating to or affecting the rights and remedies of creditors and by general principles of equity.

If no Event of Default (as defined in the Note) exists and if the proceeds arising out of any claim or series of related claims do not exceed $100,000, loss payments in each instance will be applied by the applicable Debtor to the repair and/or replacement of property with respect to which the loss was incurred to the extent reasonably feasible, and any loss payments or the balance thereof remaining, to the extent not so applied, shall be payable to the applicable Debtor, provided, however, that payments received by any Debtor after an Event of Default occurs and is continuing or in excess of $100,000 for any occurrence or series of related occurrences shall be paid to the Secured Party and, if received by such Debtor, shall be held in trust for the Secured Party and immediately paid over to the Secured Party unless otherwise directed in writing by the Secured Party.
