Permitted Encumbrances.

     (c)This First  Amendment  constitutes  the valid and binding  obligation of
Borrower and the Guarantors  enforceable in accordance with its terms, except as
(i) the  enforceability  thereof  may be limited by  bankruptcy,  insolvency  or
similar laws affecting creditor's rights generally, and (ii) the availability of
