E.               Variable Rate.   The Interest Rate may change during the term of this transaction.

(1)     Index. Beginning with the first Change Date, the Interest Rate will be based on the following index: the weakly average yield on United States Treasury securities adjusted to a constant maturity of three years.

The Current Index is the most recent Index figure available on each Change Date. You do not guaranty by selecting this index, or the margin, that the Interest Rate on this Note will be the same rate you charge on any other loans or class of loans you make to me or other borrowers. If this Index is no longer available, you will substitute a similar Index. You will give me notice of your choice.

(2)     Change Date. Each date on which the Interest Rate may change is called a Change Date. The Interest Rate may change June 30, 2009 and every 3 months thereafter.

(3)     Calculation Of Change. On each Change Date you will calculate the Interest Rate, which will be the Current Index plus 8.000 percent. The result of this calculation will be rounded to the nearest .001 percent. Subject to any limitations, this will be the interest Rate until the next Change Date. The new Interest Rate will become affective on each Change Date. The Interest Rate and other charges on this Note will never exceed the highest rate or charge allowed by law for this Note.

(4)     Effect Of Variable Rate. A change in the Interest Rate will have the following effect on the payments: The amount of scheduled payments and the amount of the final payment will change.

4.                REMEDIAL CHARGES.   In addition to interest or other finance charges, I agree that I will pay these additional fees based on my method and pattern of payment.  Additional remedial charges may be described elsewhere in this Note.

A.            Late Charge.   If a payment is more than 10 days late, I will be charged 6.000 percent of the Amount of Payment.  I will pay this late charge promptly but only once for each late payment.

5.                GOVERNING AGREEMENT.   This Note is further governed by the Commercial Loan Agreement executed between you and me as a part of this Loan, as modified, amended or supplemented.  The Commercial Loan Agreement states the terms and conditions of this Note, including the terms and conditions under which the maturity of this Note may be accelerated.  When I sign this Note, I represent to you that I have reviewed and am in compliance with t
