          6.          USA Patriot Act Notification. IMPORTANT INFORMATION ABOUT PROCEDURES FOR OPENING A NEW ACCOUNT. To help the government fight the funding of terrorism and money laundering activities, Federal law requires all financial institutions to obtain, verify, and record information that identifies each person or entity that opens an account, including any deposit account, treasury management account, loan, other extension of credit, or other financial services product. What this means for Borrower: When Borrower opens an account, if Borrower is an individual, Lender will ask for Borrower’s name, taxpayer identification number, residential address, date of birth, and other information that will allow Lender to identify Borrower, and, if Borrower is not an individual, Lender will ask for Borrower’s name, taxpayer identification number,
business address, and other information that will allow Lender to identify Borrower. Lender may also ask, if Borrower is an individual, to see Borrower’s driver’s license or other identifying documents, and, if Borrower is not an individual, to see Borrower’s legal organizational documents or other identifying documents.









          7.          No Change. Except as expressly amended hereby, the Credit Agreement, and all instruments, documents and agreements executed and/or delivered by Borrower to Bank in connection therewith, shall remain in full force and effect and unchanged.


          8.           Costs, Expenses and Fees. Borrower agrees to pay all costs, expenses and fees incurred by Bank or otherwise in connection herewith, including, without limitation, all reasonable attorney fees, costs and expenses of Riggs, Abney, Neal, Turpen, Orbison & Lewis.


          9.            Multiple Counterparts. This Amendment may be executed in multiple counterparts.


          IN WITNESS WHEREOF, the parties hereto have caused this Agreement to be executed by their respective officers thereunto duly authorized, as of the date first above written.
