	 	B.	Exhibit A (DEFINITIONS) of the Agreement is hereby such that the definition of “Revolving Maturity Date” is hereby deleted and replaced in its entirety with the following:


  
 “‘Revolving Maturity
Date’ means January 1, 2007.” 
  

	IV.	Legal Effect. 

  

	 	A.	The Agreement is hereby amended wherever necessary to reflect the changes described above. Borrower agrees that it has no defenses against the obligations to pay any amounts under
the Indebtedness. 

  

	 	B.	Borrower understands and agrees that in modifying the existing Indebtedness, Bank is relying upon Borrower’s representations, warranties, and agreements, as set forth in the
Agreement. Except as expressly modified pursuant to this Amendment, the terms of the Agreement remain unchanged, and in full force and effect. Bank’s agreement to modifications to the existing Indebtedness pursuant to this Amendment in no way
shall obligate Bank to make any future modifications to the Indebtedness. Nothing in this Amendment shall constitute a satisfaction of the Indebtedness. It is the intention of Bank and Borrower to retain as liable parties, all makers and endorsers
of Agreement, unless the party is expressly released by Bank in writing. No maker, endorser, or guarantor will be released by virtue of this Amendment. The terms of this paragraph apply not only to this Amendment, but also to all subsequent loan
modification requests. 

  

	 	C.	This Amendment may be executed in two or more counterparts, each of which shall be deemed an original, but all of which together shall constitute one instrument. This is an
integrated Amendment and supersedes all prior negotiations and agreements regarding the subject matter hereof. All modifications hereto must be in writing and signed by the parties. 

  

	V.	Conditions Precedent. Except as specifically set forth in this Amendment, all of the terms and conditions of the Agreement remain in full force and effect. The
effectiveness of this Agreement is conditioned upon receipt by Bank of this Amendment, and any other documents which Bank may require to carry out the terms hereof, including but not limited to the following: 

  

	 	A.	This Amendment, duly executed by Borrower; 

  

	 	B.	Payment of all legal fees associated with this Amendment; and 

  

	 	D.	Such other documents, and completion of such other matters, as Bank may reasonably deem necessary or appropriate.
