2

the imposition of any lien, charge or encumbrance upon any property of Borrower pursuant to, or constitute a default (with due notice or lapse of time or both) or result in an occurrence of any event for which any holder or holders of indebtedness for money borrowed may declare the same due and payable under any indenture, agreement, order, judgment or instrument to which Borrower is a party or by which Borrower or its property may be bound or affected, and will not violate any provision of applicable law.

If this Agreement or any part hereof, or any instrument executed in connection herewith, shall be construed or shall operate to affect the lien priority of the Security Agreement or the other Loan Documents, then to the extent third persons acquiring an interest or lien upon the Premises between the time of recording of the Security Agreement or other Loan Documents and the execution of this Agreement are prejudiced thereby, this Agreement shall be void and of no further force and effect. Notwithstanding the foregoing, the parties hereto, as between themselves, shall be bound by all of the terms and conditions of this Agreement until all indebtedness owing from Borrower to Lender has been paid.

10.        No failure to exercise, and no delay in exercising, any right, power or remedy under this Agreement or under any document delivered by Borrower pursuant hereto or heretofore pursuant to the transactions contemplated hereby shall impair any right, power or remedy which Lender may have, nor shall any such delay be construed to be a waiver of any of such rights, powers or remedies, or an acquiescence in any breach or default under this Agreement or any document delivered pursuant to this Agreement or the transactions contemplated hereby, nor shall any waiver of any breach or default of Borrower be deemed a waiver of any default or breach subsequently occurring.

11.        If any one or more of the provisions contained in this Agreement is determined to be invalid, illegal or unenforceable in any respect, the validity, legality and enforceability of the remaining provisions contained herein shall not in any way be affected or impaired thereby.
