In consideration of the mutual covenants contained herein, and for other good and valuable consideration, the Borrower and the Bank agree as follows:

o    Temporary increase in Maximum Loan Amount.  If checked here, notwithstanding the maximum principal amount that may be borrowed from time to time under the Agreement and Note, the maximum principal amount that may be borrowed thereunder shall increase from $                                   to $                                   effective                                    through                                    annually.  On                                    through                                    annually, the maximum principal amount that may be borrowed thereunder shall revert to $                                   and any loans outstanding in excess of that amount will be immediately due and payable without further demand by the Bank.

o    Change in Multiple Advance Termination Date.  If checked here, all references in the Agreement and in the Note to the termination date for multiple advances are hereby deled and replaced with “                                  ”.

o    Change in Payment Fee.  If checked here, subject to applicable law, if any payment is not made on or before its due date, the Bank may collect a delinquency charge of                                    % of the unpaid amount.  Collection of the late payment fee shall not be deemed to be a waiver of the Bank’s right to declare a default hereunder.

o    Change in Closing Fee.  If checked here and subject to applicable law, the Borrower will pay the Bank a closing fee of $                             (apart from any prior closing fee) contemporaneously with the execution of this Amendment.  This fee is in addition to all other fees, expenses and other amounts hereunder.

o    Change in Paid-In-Full Period.  If checked here, all revolving loans under the Agreement and the Note must be paid in full for a period of at least                                    consecutive days during each fiscal year.  Any previous Paid-In-Full provision is hereby replaced with this provision.

Defult Interest Rate.  Notwithstanding any provision of this Note to the contrary, upon any default or at any time during the continuation thereof (including failure to pay upon maturity), the Bank may, at its option and subject to applicable law, increase the interest rate on this Note to a rate of 5% per annum plus the interest rate otherwise payable hereunder.  Notwithstanding the foregoing and subject to applicable law; upon the occurrence of a default by the Borrower or any guarantor involving bankruptcy, insolvency, receivership proceedings or an assignment for the benefit of creditors, the interest rate on this Note shall automatically increase to a rate of 5% per annum plus the rate otherwise payable hereunder.

Effectiveness of Prior Documents.  Except as specifically amended hereby, the Agreement, the Note and the other Loan Documents, shall remain in full force and effect in accordance with their respective terms.  All warranties and representations contained in the Agreement and the other Loan Documents are hereby reconfirmed as of the date hereof.  All collateral previously provided to secure the Agreement and/or Note continues as security, and all guaranties guaranteeing obligations under the Loan Documents remain in full force and effect.  This is an amendment, not a novation.

Preconditions to Effectiveness.  This Amendment shall only become effective upon execution by the Borrower and the Bank, and approval by any other third party required by the Bank.

No Waiver of Defaults; Warranties.  This Amendment shall not be construed as or be deemed to be a waiver by the Bank of existing defaults by the Borrower, whether known or undiscovered.  All agreements, representations and warranties made herein shall survive the execution of this Amendment.

Counterparts.  This Amendment may be signed in an number of counterparts, each of which shall be considered an original, but when taken together shall constitute one document.
