after September 30, 2010 or (ii) any other covenants or provisions thereof. Nothing contained

this Amendment, Borrowers represent and warrant as follows:




	 	(a)	 	No Event of Default (as such term is defined in Section 8 of the Agreement) or event or

Agreement as amended by this Amendment.







	 	(b)	 	Capitalized terms used and not otherwise defined herein will have the meanings
set forth in the Agreement.

Bank under or with respect to the Loans, the Agreement, or any other agreement or
instrument guaranteeing, securing or otherwise relating to the Loans.







	 	(d)	 	This Amendment shall be considered an integral part of the Agreement, and all
references to the Agreement in the Agreement itself or any document referring thereto
shall, on and after the date of execution of this Amendment, be deemed to be references
