A.  Requests for Advances. My requests are a warranty that I am in compliance with all the Loan Documents. When required by you for a particular method of advance, my requests for an advance must specify the requested amount and the date and be accompanied with any agreements, documents, and instruments that you require for the Loan. Any payment by you of any check, share draft or other charge may, at your option, constitute an advance on the Loan to me. All advances will be made in United States dollars. I will indemnify you and hold you harmless for your reliance on any request for advances that you reasonably believe to be genuine. To the extent permitted by law, I will indemnify you and hold you harmless when the person making any request represents that I authorized this person to request an advance even when this person is unauthorized or this person’s signature is not genuine.

(2)  Advance Amount. Subject to the terms and conditions contained in this Note, advances will be made in exactly the amount I request.

(3)  Disbursement of Advances. On my fulfillment of this Note’s terms and conditions, you will disburse the advance in any manner as you and I agree.

(4)  Credit Limit. I understand that you will not ordinarily grant a request for an advance that would cause the unpaid principal of my Loan to be greater than the Principal limit. You may, at your option, grant such a request without obligating yourselves to do so in the future. I will pay any over advances in addition to my regularly scheduled payments. I will repay any over advance by repaying you in full within 10 days after the overdraft occurs.

(5)  Records. Your records will be conclusive evidence as to the amount of advances, the Loan’s unpaid principal balances and the accrued interest.

4.     INTEREST. Interest will accrue on the unpaid Principal balance of this Note at the rate of 8.250 percent (Interest Rate) until January 12, 2006, after which time it may change as described in the Variable Rate subsection.

A.  Interest After Default. If you declare a default under the terms of this Loan, including for failure to pay in full at maturity, you may increase the Interest Rate payable on the outstanding Principal balance of this Note.

B.  Maximum Interest Amount. Any amount assessed or collected as interest under the terms of this Note will be limited to the maximum lawful amount of interest allowed by state or federal law, whichever is greater.

(1)  Index. Beginning with the first Change Date, the Interest Rate will be based on the following index: the base rate on corporate loans posted by at least 75% of the nation’s 30 largest banks known as the Wall Street Journal Prime Rate.

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 January 12, 2006 and daily thereafter,

(3)  Calculation Of Change. On each Change Date you will calculate the Interest Rate, which will be the Current Index plus 1.000 percent. The result of this calculation will be rounded up 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 effective 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)  Limitations. The Interest Rate changes are subject to the following limitations:

(a)  Lifetime. The Interest Rate will never be less than 6.500 percent.

A.  Late Charge. If a payment is more than 10 days late, I will be charged 5.000 percent of the Unpaid Portion of Payment. I will pay this late charge promptly but only once for each late payment. This amount may then increase so as to always be the highest amount allowed by law under Minnesota Statutes 47.59.

6.              PAYMENT. I agree to pay this Note on demand, but if no demand is made, I agree to pay this Note in installments of accrued interest beginning February 11, 2006, and then on the 11th day of each month thereafter. I agree to pay the entire unpaid Principal and any accrued but unpaid interest on January 11, 2008.

Payments will be rounded up to the nearest $01. With the final payment I also agree to pay any additional fees or charges owing and the amount of any advances you have made to others on my behalf. Payments scheduled to be paid on the 29th, 30th or 31st day of a month that contains no such day will, instead, be made on the last day of such month.

Each payment I make on this Note will be applied first to interest that is due then to principal that is due, and finally to any charges that I owe other than principal and interest. If you and I agree to a different application of payments, we will describe our agreement on this Note. You may change how payments are applied in your sole discretion without notice to me.
